12.A1.2. Some problems of improvement of Criminal Code of Georgia. /Sh. Phaphiashvili/. Metsniereba da Tskhovreba. – 2013. – N1(7). – pp. 312-319. – geo.; abs.: geo., eng.

The paper deals with some problems of improvement of the Criminal Code of Georgia and some viewpoints of the author in this direction, particularly: 1. The impor­tan­ce of considering slander and insult as a crime in criminal law and respective changes in the Criminal Code. 2. According to the author, existence of life and long term imprisonment as a type of punishment is ineffective. That is why it is expedient not only to prohibit the summary punishment, but it is also necessary to substitute a long-term imprisonment with a short-term one. 3. It is recommended that except for a calculated murder committed in aggravated circumstances, the punishment for all other types shall not exceed 10 years of imprisonment. As for the calculated murder committed in aggravated circumstances, the punishment here should not exceed 15 years. According to the author, unlimited widening of the concept of bribery and the bribe is considered to be wrong. The bribe cannot be an intangible asset. As for bribery, it is a bilateral crime and is considered completed from the moment of giving/taking a bribe and thus interpretation of Articles 338 and 339 of the Criminal Code under which bribery is considered completed from the moment of offering or promising any unlawful benefit is erroneous. Ref. 9.

12.A1.4. Liability for damage emanating from a construction with increased danger. /R. Tsintsadze/. Metsniereba da Tskhovreba. – 2013. – N1(7). – pp. 324-330. – geo.; abs.: geo., eng.

The article deals with the tortuous liability for the damage caused by increased danger emanating from a construction. Such sources of increased danger, based on their properties, are electric installations, energy-storage and energy-supply facilities, machine tools, mechanisms, inflammable and explosive substances, poisonous substances and poisons, devices associated with the use of atomic energy, building sites, vehicles, and many other things that are beyond the human control and represent an increased danger to those around. The liability for damage resulting from a source of increased danger is characterized by rather significant peculiarities. Here the liability ensues not only on the basis of a deliberate or careless guilty attitude of the delinquent, but also without the fault, being an exception to the general rule of culpable liability. Provisions of Articles 997, 999, 1000 and 1005 of the Civil Code of Georgia are analyzed and corresponding viewpoints expressed in the paper. Ref. 1.

12.A1.5. International and economic relations of Ge­orgia and their legal regulation. /V. Abakelia/. Me­ts­ni­ereba da Tskhovreba. – 2013. – N1(7). – pp. 331-334. – geo.; abs.: geo., eng.

The article deals with economic links, relations with various countries of the world and legal regulation of close relations with them. As a determinant of the mentioned it is considered that the international finance law should be separated from the finance law, as one of the fields of law, and be formed as a separate field. As a result, Georgia, given all the legal aspects, will be able to get closer to the world and minimize thus all the drawbacks mentioned above. Ref. 6.

12.A1.6. Globalization and legal problems of the Ge­orgian industrial production. /T. Kiladze, T. Ru­kha­d­ze/. Metsniereba da Tskhovreba. – 2013. – N1(7). – pp. 334-336. – geo.; abs.: geo., eng.

The paper deals with the aspiration of Georgia to participation in the global economy, the role and importance of transnational companies in the global economy, the problems faced by Georgia, the solution of which will help to reach the set goal and export its products to global markets. Also discussed is the current state of the Georgian industry, the principal problems of its legislative support, such as: defective tax administration, the unhealthy competitive environment, and nonexistence of antimonopoly rules. Ref. 3.

12.A1.7. Administrative appeal and peculiarities of its filing. /D. Khobelia/. Metsniereba da Tskhovreba. – 2013. – N1(7). – pp. 337-339. – geo.; abs.: geo., eng.

The possibility of filing an appeal in courts is a universal right of citizens guaranteed by Article 42 of the Constitution of Georgia. Any interference with the exercise and/or violation of this right is unacceptable. The prejudicial appeal procedure is exactly what interferes with exercise of this right. Therefore, the prejudicial procedure should be abolished so that every person could directly apply to the court for protection of own rights. Ref. 6.

12.A1.8. Issues of criminal liability of the principal and accomplice. /E. Gventsadze/. Metsniereba da Tskhovreba. – 2013. – N1(7). – pp. 340-345. – geo.; abs.: geo., eng.

Limited complicity is considered to be incompatible with to the Georgian criminal law. First of all, according to the legislative wording, “Criminal complicity means intentional participation of two or more individuals in the commission of an aforethought crime”. (Article 23 of the Criminal Code of Georgia). The law directly mentions the commission of a crime rather than wrongdoing. Based on the above, if a person has committed a wrong act and his guilt has not been established, the person may not be held criminally liable. This runs counter to the principle of criminal liability. Thus, since there is no crime without guilt, there could be no complicity in it. Ref. 10.

12.A1.9. Importance of causal connection in the theory and practice of the criminal law. /J. Gabelia/. Metsniereba da Tskhovreba. – 2013. – N1(7). – pp. 346-351. – geo.; abs.: geo., eng.

The article deals with the current issues of the criminal law such as causal connection between action and result. Theories of causal connection and its problems of realization in judicial practice are shortly discussed. Importance of determination of causal connection is grounded in investigation and judicial practice, while giving a correct qualification to the action. Ref. 11.

12.A1.10. Legal nature of leasing. /K. Bzishvili/. Metsniereba da Tskhovreba. – 2013. – N1(7). – pp. 352-357. – geo.; abs.: geo., eng.

Despite the changes made, the restoration of a number of articles of the former wording is considered to be expedient. Such are, for example, the norm on lease agreement (Article 577), other leasing rules (Article 580). In general, the chapter concerning leasing in the Code lacks a reference to the consistency of the Criminal Code provisions. Ref. 8.

12.A1.11. Private life in the context of the conflict of values. /M. Bichia/. Metsniereba da Tskhovreba. – 2013. – N1(7). – pp. 358-361. – geo.; abs.: geo., eng.

As outlined in the study, the solution of a conflict of values needs a careful approach. At the same time, freedoms should not exceedn definite limits, for if freedom violates other right, it will lead to a wrongdoing rather than to a conflict of interests. Thus, all the specific cases should be throughly analyzed when there is a conflict of interests, because all cases are indivi­dual. Accordingly, the way of solving the conflict of interests can vary in different cases. It is also worth noting that sometimes it is more relevant to protect personal life than public interest. Although, weighing of values and protecting the principle of proportionality can be considered as common criteria in solving the conflict. Ref. 10.

12.A1.12. The Law of credit rating agencies as an independent branch of law and its subject - credit ratings. /N. Jibuti/. Metsniereba da Tskhovreba. – 2013. – N1(7). – pp. 362-375. – geo.; abs.: geo., eng.

The paper emphasizes that even though there exists enough factors for rapid creation of law of credit rating agencies, as the independent branch of law, it is only on its early stage of development. Relationships related to the credit rating market have gained such an importance all over the world that the creation of legal framework for them became unavoidable. Historically, the need of legal regulation has shown itself at several points during the time of different financial and economic crises, but its importance was especially demonstrated after the 2008 global financial crisis. So, the several attempts began for forming the subject of law of credit rating agencies for defining different credit categories, etc. The paper discusses the rationale of rating, different rating categories and argues that the subject of credit rating law is management of rating resources, of technologies for processing the ratings, of their provision, supply, transactions and consume. The credit rating law is mainly borne in the sphere of relationships in financial, banking, informational law and then it develops its own subject of regulation. Ref. 27.

One of the most important institutions of legal process – the constitutional guarantee for protecting human rights – the principle of presumption of innocence is discussed in this paper. Existing assumptions about the presumption of innocence are analyzed, a number of principle resistances and defaults connected to it in literature and normative acts are noted, and the legal nature of the principle is clarified.

This paper deals with the novelties introduced in the Georgian criminal procedure law, specifically the changes related to the roles of the prosecutor and the defendant, in particular, their right to access the evidence on equal basis. In contrast with the prosecutor, a lawyer is currently not authorised to carry out all investigative activities; however, the defendant may retain certain part of the evidence for the later stage of litigation, whereas the prosecutor has to release it right from the very beginning. Furthermore, the defendant could be granted a right to carry out any investigation activity. To sum up, the introduction of the current Criminal Procedure Code has bought forth tratther positive changes in the Georgian legislation. Ref. 7.

12.A1.15. Subrogation in insurance law. /I. Nozadze/. Metsniereba da Tskhovreba. – 2013. – N1(7). – pp. 381-385. – geo.; abs.: geo., eng.

The article deals with the essence of the principle of subrogation presented in Article 832 (in the insurance section) of the Criminal Code of Georgia and is used actively in the regulations of insurance relations. Its features are presented in comparison with other similar regulations. The correct use of this norm was so problematic issue in judicial practice that the Supreme Court made a significant clarification over this issue. The aim of this article is to present the essence of the principle of subrogation and the drawbacks in Article 832. Ref. 5.

12.A1.16. For precise understanding of the concept, essence and meaning of indirect evidence. /Sh. Pa­pi­a­shvili/. Metsniereba da Tskhovreba. – 2013. – N2(8). – pp. 76-81. – geo.; abs.: geo., eng.

The article deals with the place of circumstantial or indi­rect evidence in the system of a cycle of evidences; its theoretical and practical significance is substantiated. The author does not share the viewpoint of those processionists, who neglect a possibility of practical usage of indirect evidence; contrary to this, the essence and significance of indirect testimony in respect of discovering the main fact of the case of investigation and its fast and full exposure are discussed against the background of investigational-judicial practice. The defi­ni­tion of the concept of indirec efvidence, as well as the ways and means of obtaining indirect evidence are convincingly established. Ref. 1.

In this publication the author makes a comparison of federal and unitary systems after the example of a territorial organization in the USA and France. According to the views presented in this article, modern federal and unitary systems have many features in common because the developed self-government and, generally, the distribution of powers on a vertical based on the subsidiary principle ensures modification of the centralized unitary system and its similarity with the federal system in legal terms. According to the author, the modern democratic process gradually deprives the territorial organization of the state of the political basis and places it within legal frameworks defined by democratic parameters.

12.A2.4. Social-economic equality. /V. Khizanishvili/. Ekonomisti (Economist). – 2012. –N1. – pp. 37- 40. – geo.; abs.: eng.

Equality is one of the most important concepts of social philosophy. Social equality means equal access of people to social liberties, rights and prosperity. Equality, as an economic category, can be divided into three parts: 1. Equality of prosperity; 2. Equality of opportunities; 3. Equ­ality of resources. The tendency of the modern world is characterized by growing social-economic inequality, which is characterized by a deficit of social public resources – money, power, education and prestige with unequal distribution among the different social classes of people, which shows a distinct differentiation towards the social stratification.

It is significant to use social marketing strategy for improving health care, ensuring an environmental improvement and increasing people’s well-being in the country. The concept of social marketing, despite its topicality, is not popular yet at Georgian academic and public levels. Only a small number of commercial organizations is engaged in social projects and benefit from them by building up a positive corporative image and loyalty of consumers. Social marketing is an important instrument to settle the interests’ conflict of business and society. Ref. 10.

Information systems have to be designed to meet the way in which managers tend to work. Research sugge­sts that a manager continually addresses a large variety of tasks and is able to spend relatively brief periods on each of these. Given the nature of the work, managers tend to rely upon information that is timely and verbal (because this can be assimilated quickly), even if this is likely to be less accurate then more formal and complex information systems. Managers play at least three separate roles: interpersonal, informational and decisional. MIS, in electronic form or otherwise, can support these roles in varying degrees. MIS has less to contribute in the case of a manager's informational role than for the other two. Three levels of decision making can be distinguished from one another: strategic, control (or tactical) and operational. Again, MIS has to support each level. Strategic decisions are characteristically one-off situations. Strategic decisions have implications for cha­nging the structure of an organisation and therefore the MIS must provide information which is pre­cise and accurate. Control decisions deal with broad policy issues and operational decisions concern the management of the organisation's marketing mix. To conclude we can say, that multinational marketing infor­mation systems are intended to support management de­­cision-making internationally. Hence, therefore MMIS is more complex phenomenon then MIS, because it has to bring several MIS of different countries in coordination. Fig. 2, Ref. 7.

The study is performed with the use of the Generations and Gender Survey (GGS) database. The findings of the study allow to conclude that restrictions of the collective model are valid for describing female labor supply in Georgia and that the sharing rule is an important predictor of female labor supply.

Introduction of program budgeting in Georgia is a constituent part of the ongoing reform of the government finance management As the other countries’ experience has shown, the program budgeting is a rather progressive system, which, in contrast to previous ones, implies the outlining of annual budget assignments in line with program budgeting, serving implementation of a specific priority; has a probable implementation period; has the implementing body and where the expected outcomes and their assessment indicators are determined in advance. The said approach facilitates an increase in the efficiency and effectiveness of Government expenditure which, in turn, is the most important priority and objective of the government finance reform.

The government finance and budget management strengthening was and remains the main priority for the Government of Georgia. From 2004, there have been accomplished significant changes to improve the government financial system and in compliance with international standards. These reforms with improved economy have significantly supported stability of the government finance system. A transition from one-year to multi-year state budget planning has been accomplished. In 2006, the mid-term expenditure framework (MTEF) principles, serving as the basis for drafting the Basic Data and Directions (BDD) document were developed. In 2008, a transition to GFSM-2001 classification was carried out. In 2010, a new Tax Code of Georgia was adopted and introduced, which has made the budget process more perfect and concise. 2011 was very important for the government finance reform. A methodology of program budgeting was elaborated and introduced. For the first time, the budget was drafted according to the program budgeting principles. The changes concerning the government audit service, internal finance monitoring, and government procurement in light of the government finance structure management reform were also important. In addition, the management system was improved; the State Treasury electronic service, electronic systems of budget preparation and planning were introduced. The Government of Georgia continues active work to introduce innovative approaches to further improvement of the budget process, transparent and efficient management of the country’s finance, because the efficient financial management of governmental funds will ensure long-term economic stability and fiscal sustainability of the country.

After the collapse of the Soviet Union, economic relations between Georgia and Russia have developed in a contradictory manner and appear even more complicated at present. The paper explores the post-Soviet economic relations between Georgia and Russia. During the two decades of post-Soviet development a lot of unresolved problems has been accumulated between Georgia and Russia. Despite the extremely strained political relations, and breaking off of diplomatic relations, economic activities between the two countries have never stopped. Positive results of the Georgian-Russian negotiations about Russia’s accession to the WTO create the real possibilities to improve the relations between these two countries. Ref. 28.

12.A3.24. The individual behavior and its foundations. /T. Arnania-Kepuladze/. Ekonomisti (Economist). – 2012. – N1. – pp. 22-26. – geo.; abs.: eng.

The article discusses the features of individual behavior foundations. The contemporary literature defines predominantly genetic-biological aptitude of human behavior and environmental-based factors of behavior, including physical, psychological, social factors, etc. The author distinguishes the special factors and temporal factors of environment. The special factors are understood as politic-economic-culture-based differences between societies, organizations, etc. The temporal factors are divided into two parts: first, the individuals’ forming environment is explained as development/movement from past to the present or as a process of individuals’ upbringing and socialization and, second, the situational environment or present time specific for every moment and the effected individuals’ decision-making and behavior. Based on such perceptions, the author introduces an individual behavior model, where the individual behavior is considered as interdependence of four basic elements: individual’s nature-based aptitude, special factors, past period, or individuals’ formation/sociali­za­tion process, and the situational environment existing at each given moment and the effected person’s possibilities to realize own goals and, therefore, the individuals’ decision-making and behavior.

Researches in the psychology of leadership show that the best manager should also be a leader. The problem of having a competent and responsible leader is most urgent and complex in the world of business. Traditional models of leadership fail to cope with new economic and political problems. Modern and innovative intellectuals are in great demand under conditions of globalization. The successful leader is judged not by what and how he does, but by how he manages to make others do it. Leadership is very important at any level in large, medium and small enterprises and is thus the main ingredient of the effective management. Ref. 5.

The article deals with the improvement of tax planning – one of the most important functions of the financial management of a corporation. The foreign experience of a tax system organization (UK, France, Italy and Germany) is discussed. In almost all western countries liberalization of the basic income tax and corporate income tax system appears to be the main direction of this system’s reform; in particular, tendencies for reducing income tax have been identified in most EU Member States lately. Today, the tax planning issues lack a uniform, consistent and science-based approach. According to the level of management differentiated are types of the state, corporate and individual tax planning. The tax planning process’ algorithm cannot be considered as full and unambiguously consistent activities, the strict compliance with which will inevitably lead to a reduction of the taxable amount; however, their complete disregard may also cause a significant growth of the taxable amount of the company’s (firm’s) tax base. Consequently, given the corporate tax planning practices, the perfection of the main planning principles and the process characteristics, tax optimization methods and "tax pressure" may make it possible to further improve the tax planning aimed at improving the corporate financial situation of corporations.

The important issues of interest gain control, the handling of which would significantly increase the taxable base, are discussed. A study of taxes shows that the tax administration forms greatly influence the rates of development of a country. It should be noted that the correct tax policy has an important role in the stable development of the country. The improvement of tax administration is one of the typical problems in Georgia. Given this, it is important that scientists and economists participated in the process of the formation of this issue. The methods of administration where the interests of both the State and the taxpayer will be maximally taken into account should be developed. Ref. 6.

In March 2001, Michael Porter wrote an article in the Harvard Business Review on the challenge the Internet presented to strategy making, and to the models he had developed to help explain strategic decisions and achieve competitive advantage. A decade later, it se­ems useful to review his arguments, understand the implications of the Internet for today’s strategy-makers and, in particular, consider the impact of the Internet on small business. This impact is examined based on the Coase article The Problem of Social cost published in 1960 on theoretical postulates of free market regulatory capabilities and zero social transactions and well defined property rights, which are subject of different failures in real life situation. Finally, the article (which is presented in two parts) concludes with some thoughts on the significance of e-business in modern business – to be examined for the first time in Georgia.

For the purpose of attraction of foreign investments and implementation of investment projects in Georgia it is necessary to create a good investment climate. The investment attractiveness is a generalized parameter and the investment activity is a parameter resulting from it that determines an actual development of the investment activities. The investment attractiveness in return depends on two system parameters: investment potential and investment risks of the country. These two parameters in particular are to determine the investment attractiveness of the social and economic system. As regards the investment climate of the country, subject to the aforementioned, in 2011, the relations existing between Georgian and Russia were specified as the risk factor assigned to Georgia by Moods Investors Service. In particular these strained relations along with several other ones hinder Georgia in the attraction of additional investments. As regards the investors, they manage to invest funds to our country, notwithstanding the current situation. Due to a high risk on such investments, they demand a high risk premium as compared to investments implemented in developed economies. In particular, our country aimed at development should obtain investments from our neighbor countries, such as Turkey, Azerbaijan, Ukraine, and Russia. At the same time, it is necessary to continue relations with the internationally recognized and well-known financial organizations and other donor countries, with which the country has already established certain relations.

Globalization is considered as a process of world economic, political and cultural integration and unification. The process of globalization is characterized as a unity of certain factors, the important one of which is to ensure membership in international organizations, such as WTO, Euro-Atlantic Alliance, European Union, etc. There is a positive and negative assumption of the globalization process in the society. Globalization does not have to be considered as an unambiguous evaluation – either positive or negative. It covers both. The process of globalization gives the opportunity to increase production, salaries and raise the standard of living for improving the conditions of all the participants. The negative aspects associated with are not a sufficient ground to reject the process. This is an objective inevitability and every subject of the international community has to become accustomed to it. Ref. 13.

Competitiveness of Georgia is mainly based on the use of comparative national advantages and mechanisms of price competition. An analysis of the competitive potential revealed that despite the current unattractive state, the country has a number of competitive advantages. First of all, Georgia has a favourable geopolitical location and can serve as an important transport corridor; second, the availability of relatively cheap and skilled labour force is important for developing the human capital and high technology use prospects.

Economic globalization is an inevitable process and Georgia, despite its poorly developing economy, has to promote this process. Geopolitical location of the country is convenient for regional globalization. The shortest way, which connects Europe with Asia, passes through the territory of Georgia. For the purpose to increase the transit competitiveness of transport, Georgia should improve transport infrastructure and take necessary organizational measures. These include: the State support of the transport field to attract cargos; constant coordination with Central Asian countries and regulation of tariffs; reduction of rates for loading and unloading works to compete with the ports of Russia and Turkey.

Corruption is known to adversely affect national economies in all circumstances. In addition, as the research by well-known scientists shows, these regularities are not working in all the cases. In the countries, where inefficient system of management dominates, the corrup­tion may replace the rule of law and give stimulus to the economy. As a result, in a short-term period, corruption may render a positive impact on economic growth of the country. Ref. 12.

Research of gender aspects in business and economy in general is given more and more attention among various directions of economic thought. As already noted, studying of gender aspects of economy was observed in the 60-70s of the last century. The methodology of research of gender problems in economic science is so diverse that it sometimes leads to rather inconsistent conclusions. Nevertheless, the role of this research for the development of a new scientific direction – “gender economy” is important.

The sale of commodities is affected by many factors: correct arrangement of goods in the trading hall; their appropriate packaging; an organized and helpful assistant; convincing the customer that the goods bought by him will certainly be useful for him. A good selling agent has to possess definite technical skills: a distinguished selling agent should be the partner of the company’s marketing service where he is employed. A selling strategy should be orientated on customers and their influence. The better we know the customers, the easier we realize the selling strategy; a successful selling strategy does not mean working out far-reaching plans or any sly methods at all; it means to understand the customer’s mood, to know the risk factors affecting the customer’s hesitation in making a decision. The experience shows that there are always ways of increasing the efficiency of current selling, for which it is not necessary to raise the investments in large quantity. That is why it is better to manage and solve the problems that interfere with the sale of commodities by the rational and efficient use of the available resources. Ref. 3.

Relationship with the banking sector is essential for any business, both in terms of service and crediting. For a small business bank loans are vital, its development is impossible without capital. Social and economic benef­its of small business to a large extent depend on the sta­­bility of banks. The improvement of the issues of em­p­loyment and the reduction of unemployment in Georgia are directly dependent on the expansion and support of small business by issuing cheap bank loans. Ref. 4.

Many companies producing consumer goods are managing their business like transnational corporations in order to adapt their production to the requirements of local markets. Today, many large and widely known companies are trying to globalize the management structure and for that abolish artificial geographical barriers. Such a global type of organizations has been coined “without borders”. The aim of such organizations is to ensure the maximum globalization of business on the basis of a geocentric approach. The global transformation process of one of the companies during a definite period is considered. Generally, such process is implemented in three stages: passive stage, first active measures, and permanent international activity. Each further stage requires more global investments and correspondingly is connected with increased risk. Ref. 8.

The manager has regular contact with senior management, hired employees, colleagues, customers, partners and with others. How professional he does it depends on the efficiency of his work, how he is doing business etc. Specialists in any field of their activities should be dependent on the knowledge of human values ​​and requirements, so that they can guess the human resources and the desire to meet them. All these are carried out both during the moral-psychological and business contacts. Of course, knowledge of psychology helps us in providing motivation of behavior and influences on the behaviors of individuals; it is necessary to organize the work in such a way that it does not cause any stress in human resources.

One of the priority directions of economic reforms in Georgia is to work out and realize an investment policy that ensures high pace of economical development and raises economical effectiveness. Today, an approach towards foreign investment and its role has not been realized yet on the governmental and political level. The governmental policy principles, as well as active mechanisms of government policy regulations have not been sufficiently worked out. In order to raise investment inflow in Georgia, a united government policy aimed at creating the favorable climate and improvement of the country’s investment attractiveness should be worked out and consistently implemented.

Any bank product is associated with certain risks, an analysis and assessment of which will definitely help the customers to make rational decisions, especially in the case of deposits and/or loans. The currency risk belongs to this category. The presented study has shown that only a few commercial banks offer the tools for foreign exchange risk management to their customers in Georgia. In particular: JSC TBC Bank, JSC Bank Republic, JSC VTB Bank Georgia and JSC Bank of Georgia. Respectively, the number of the actual consumers is rather small. During the research two main reasons were outlined – the information vacuum concerning the main point and management (hedging) of currency risks and the cost of hedging. Ref. 9.

Deflation (negative inflation), if it lasts for a long time, has a negative impact on economic development in general. In the short term, it significantly reduces business activity in a country. In Georgia, as a result of the deflation processes commenced in the second half of 2011 in Georgia, the volume of consumption and consumer price index has dramatically fallen. Formed in 2012, the negative inflation may have a negative impact on business activity, such as the slowing down of business activity as a consequence of the fall in the price level, lower incomes, worsening financial statements and complicated access to credits.

The paper discusses the rationale and the limitations of the disclosure tool for achieving effective investor protection and addresses the problem of defining the notion of “EU retail investor”. It considers the findings of the behavioural economics about the limited cognitive capabilities of investors, who find it difficult to process the supplied information. It is argued that the disclosure cannot be seen as a potent tool for the retail investor protection unless it is supported by a complementary measure, such as financial literacy. Moreover, the recent reforms, which still refer to the dubious notion of “average retail investor’’ and are concentrated on reducing the size and the complexity of the disclosure document, while still striving to empowering investors with the information, will not be successful unless the issue of investor education and the fragmented EU retail markets is addressed appropriately. The paper is sceptical whether the current reality of obvious differences between retail markets, investment patterns, behaviour, tradition etc. in EU Member States gives the strong basis for success of standardized rules, which are the main goal of EU regulators. It seems more reasonable first to address the problem of fragmentation of market and develop comparable level of investor competence in different EU member states, before starting to achieve standardization in the EU securities disclosure.

The theory of “big waves” by the Russian scientist D. Kondratieff that is closely related to the evolutionary theory of innovations by J. Schumpeter is considered. Within the given view are offered some conclusions: global financial and economic crises are a product of the post-modernist transition period, which economic maintenance is expressed in transformation of industrial economy to the post-industrial. The major reason of financial and economic crises is fast and uncontrolled distribution of financial innovations, which destroy the equilibrium of financial markets. Ref. 6.

Georgia creates a new system on the basis of the already implemented or implementable reforms that intentionally or unintentionally are influenced by the globalization process which accompanies the given stage of development. The transition phase is characterized of innovation problems that require immediate response from the government and the conduct of the appropriate reforms that are aimed at the growth of various economic indicators. First of all, it must necessarily involve farms so that the village would regain its function which has been lost lately. In particular, it is necessary to develop the rural – agricultural infrastructure, to employ the rural population, to increase the domestic and export production, and to stir up innovation-related activities in order to cope with all these problems.

Globalization is the main trend of the development of the world economy. The most important determinant factors of the economic globalization are the creation of a single system of the world economy, which is associated with the epoch of capitalism development. On the way to the economic globalization the great role is played by transition from the closed national economic system to the open economy and the process of deepening the economic integration between countries. Two basic models have been outlined in the process of economic globalization: the neoliberal model – market-based mechanisms of the economic development and second model, which means economic development and management through targeted social and economic programs. The key roles in the globalization process play Transnational Corporations (TNC) together with a group developed countries and international financial-economic organizations. TNCs have huge industrial, scientific and market potentials; they create the world GDP and control the major part of the international trade and investment. In the future, the role of TNCs will be increased in the economic development and globalization together with the development of the transnationalization process. Ref. 7.

Negative shocks for the financial system are considered: depreciation of Georgian lari, decrease in the speed growth of real gross domestic product, increase of interest rate and decrease of confidence in the financial system being evidenced by drain of deposits. An analysis of different shocks shows that the main risk for the system is depreciation of the currency rate caused by high level of dollarization. The stress test is aimed at intends at complementing the measurement of risks under abnormal market conditions with the estimation of potential economic losses of the bank in order to establish the bank sensitivity to variations of risk factors and identify the factors most affecting the bank portfolio.

Agricultural insurance is very important for developing the sector. It comprises insurance of harvest, cattle, forests, aquacultures and green-houses. The aim of agricultural insurance is to protect farmers and stabilize their revenues. Risks of production, natural resources, finances and marketing are very important for agriculture. The production risk-related dangers are: unfavourable climate, parasites or diseases and fires. The risks of natural resources include: unfavourable soil conditions, deterioration and lack of water. The following can be insured: annual harvest, harvest of many years, greenhouse harvest and forests. These crops can be insured against individual and many risks. The agricultural insurance products include insurance of costs of production and crop capacity. The article also reviews how to implement agricultural insurance, its main functions, liabilities of the insurer and policy-holder. Ref. 2.

An economic analysis method implies a dialectical approach to the study of economic processes, their origin and development. The major task of analysis is all-round assessment of a business plan as well as of all kinds of plans and programs. The method also implies the use of all the rules and means which enable to study and evaluate the economic activity. An economic analysis considers all economic events in the development process in intercommunication.

The world still faces the acute economic crisis. A precondition of such a crisis was a rapid increase of prices of real estates in the USA and a large amount of mortgages, unsecured and high risk credits issued under variable interest rate. Mortgage crisis initiated in the USA resulted in a dramatic impact on the banks at first; it spread through the real estate market, occupied any and all sectors by the safety mechanism and developed throughout the world. As a result of these processes, the economy of America went into recession; consequently, all banks were closed one after another. It should be emphasized that the most significant obstacle of recession are the people themselves: the sense of pessimism emerging in the society changes its economic behavior, individuals become more prudent, reduce the risks and investments.

The study shows that the import of poultry meat exceeds the export 25 times, whereas the export-import ration makes sometimes 1:56. The studies show that in order to balance the eggs and poultry meat export-import ratio, poultry farms should be built in Georgia. Ref. 6.

The objective of the current paper is to explore the impact of services inputs on export performance of manufacturing firms in transition economies. The results of the study provide a new understanding of the consequences of trade liberalization in services sector. In particular, positive impact of services sector efficiency on export performance of manufacturers is revealed. Thus, advancing liberalization reforms in telecommunications, electric power, railway transport, road transport, and water distribution sectors as well as in banking sector will stimulate expansion of export activities of manufacturers. Along with services impact, we find that firm specific characteristics such as introduction of new products, investments in research and development, employment of advanced technologies, and employee skills are key drivers of export performance in manufacturing sector in transition economies. Firm’s size and foreign investments do matter as well. The results of the study have several policy implications. The first insight is that an efficient service sector infrastructure represents a strategic and underexploited resource of export enhancement that can be influenced by policy makers. To stimulate export performance of manufacturing industries policy makers must emphasize further reforms and liberalization of their services sectors. These reforms must be focused on providing adequate access to services for downstream industries and thus on reducing their costs of doing business. Moreover, government should create favorable conditions for attracting foreign direct investments and encourage investments in innovation, research and development, employment of advanced technologies. A final policy point is that reducing trade related costs through trade and customs procedures facilitation would also increase exports. Tab. 1, Ref. 18.

Based on an analysis of a modified version of the standard Keynesian Model of a product market, it is shown that a change in the average tax rate has a complex effect on aggregate demand. Depending on the marginal propensity of households to consume and the marginal propensity for government purchases, an increase in the average tax rate may lead to either a decrease or an increase in aggregate demand. In this case, since the parameter of marginal propensities to purchase is easily regulated, by selecting its appropriate value the government can purposefully use a tax increase to stimulate or to reduce aggregate demand.

The recent world economic crisis had a huge impact on Georgia’s social and economic framework. The sole possibility to avoid the negative influence of global deteriorating economic tendencies is to base economic and, first of all, industrial development of the country on national natural resources and commodities. However, extensive use of Georgia’s mineral commodities is slowed down due to lack of possibility to capitalize them at early stages of exploration. The present article proposes a new economic method, which allows computing the Net Present Value of an eventual mining enterprise at the early stage of exploration. In turn, such analysis provides indicators not only for assessment of the volume of possible venture investment in exploration but also for immediate capitalization of eventual commodities on international commodity markets.

The reliable and quality provision of natural gas is vital for society and therefore requires the state regulation. One of the main components of the regulation is the fixing of tariffs and an improvement of the existent methodology. It is shown that many of the parameters of natural gas sector are of an indefinite nature, which requires the development of novel approaches for their processing. The using of fuzzy sets is suggested as one of the ways to improve the determination and regulation of natural gas tariffs. In our opinion, this will allow the fixing of tariffs more adequate. In the present paper, the main tasks for the implementation of a new approach for foxing natural gas tariffs are considered. Ref. 6.

12.A3.87. The modern concept of business engineering. /A. Sichinava, Z. Chkhaidze, Sh. Veshapidze, D. Sekhniashvili, N. Chikviladze/.

The concept of business engineering has gradually evolved from reengineering – a method of business reorganization and transformation of existing business processes. Its concept has been developed: a system of establishing business as an engineering science and means for designing and managing business processes on the innovative basis. A determining factor is approach, when business processes are the main object of management in an establishment and processing and projecting approach. In terms of processing approach organization is a set of processes (while in case of functional approach – a set of functions) and thus management of an establishment implies management of processes. Every process has its goal. Achievement of desirable results depends on their effectiveness. Every process has its sub-level goals. After achievement of sub-level goals higher level goals are being reached and finally the company’s goals. By managing processes and their constant update high effectiveness of a firm’s activity is achieved. Business engineering is related to many sciences. This interconnection (opportunity to resolve tasks and achieve goals on the basis of knowledge accumulated in variety of fields) indicates that it is an interdisciplinary phenomenon. Its division into separate directions was defined by the fact that at the modern stage in order to achieve high results it is necessary to ensure tight interconnection between "exact" sciences and natural sciences, engineering, humanity, economic, and legal disciplines: mathematics, physics, chemistry, engineering, construction, economics and business, marketing, management, jurisprudence, mo­dern financial, information and communication, legal polytechnic, socio-cultural and cross-cultural fields, psy­chology, sociology, global technologies of mega econo­mics and many others.

The issue of historical destiny of modern capitalism and the paradigm of liberal economy is being actively discussed for about 10 years in certain circles of political elite, in the books of scientists and publications of publicists, in the newspapers and scientific magazines. It is supposed in the present paper that “modern capitalism has exhausted itself and does not fit the modern world standards”; Obviously, it is difficult to predict in what kind of system will the world live in the future, but scientists think that it could be more humanistic social-economic system – the Western type socialism and in the distant future it will be replaced by a non-party system – harmonious society. In January 2012 at the World Economic Forum in Davos, Switzerland, was said that the modern system of market economy turned out to be both unfair and unstable, and in addition it became unacceptable.

In this work a decision support technology to minimize risks while choosing among competitive investment projects is proposed. The technology combines two fuzzy-statistical methods, providing two stages of investment projects’ evaluation. At the first stage preliminary selection of projects with small risks is made on the basis of the A. Kaufman’s Theory of Expertons. The second stage makes more precise decisions using the new possibile aggregation of OWA operator – AsPOWA. This instrument is applied to a relatively small number of projects, selected during first stage, to compare and sort out high-quality projects. For the latter, the recommendations to provide credits are made. The article provides calculation examples that explain the work of the offered technology. Tab. 4, Ref. 6.

In this work a new generalization of the OWA operator (introduced by R.R. Yager) is presented. Our focus is directed on the construction of the aggregation OWA operator – AsFPOWA in the possible uncertainty environment. For the illustration of the applicability of the new aggregation operator – AsFPOWA an example of the fuzzy decision making problem regarding political management is considered, where we study a country that is planning its fiscal policy for the next year. Several variants of the new aggregation operator are used for the comparing of decision making results. Tab. 5, Ref. 5.

The theoretical prerequisites for existence of natural mo­nopolies, their origin, privileges and destination are presented. The introduction of the governmental control in the sphere of anti-competitive policy in Armenia star­ted actually from naught, for in the past the manage­ment of economy had been carried in an administrative-directive way which impeded free economic competi­ti­on. The experience shows that achievements in the eco­nomic reforms (especially in the transition econo­mies) greatly depend on the state structure, which balances the monopolistic processes and regulates competitive relationships. A complex of measures di­rected at the restriction of the activity of monopolies, prevention of monopolistic agreement, also at the crea­tion of a competitive environment should be worked out in the sphere.

Risk reduction means a possibility of reducing the loss or probability of occurrence of unwanted conditions. Despite the probabilistic nature, the risk needs manage­ment, and in many cases it can really be successful. Risk management requires: (i) creation of a work prog­ram and methodology; (ii) risk assessment and analy­sis; (iii) setting measures for risk reduction or elimination; establishment of risk management units; risk pre­duction. Risk management (which is used in the management process to prevent reduction of income) is based on: risk avoidance, risk to take, risk insurance, risk transfer to the third person, and various methods of reducing losses. The most popular and effective methods of protection against risks include: insurance, reser­vation or self-insurance, diversification and limitation.

The marketing theory is developing in parallel to the general direction of economic sciences. Due to this it has a narrow usage. For this reason L. McConnell and C. Brew called it as a science about “making money”. Since this theory has no methodological basis, it cannot generalize its subject of study. As a result, the economic is unable to give a necessary evaluation to the marketing tendencies, which make systematic changes in modern economy and, in general, public structures – which reaches the bottom of the relations of a producer and a costumer. If this drawback is overcome, it will enable us not only to enrich general economic disciplines with necessary generalizations but to make these disciplines more interesting both for economic and non economic students. It is clear that an approach to teach the common theoretical issues concerning marketing – their connection with the practice – should vary according to faculties. Ref. 3.

In the paper it is proved that the educational reforms carried out in the last years in Georgia have failed to provide improvements of quality of teaching system and scientific researches. The SWOT analysis of the new concept of reform of education and science manifests its strengths and weaknesses. It is stated that Georgia is still not able to provide appropriate intellectual and financial resources to introduce the Tenure System and Harnack’s principle; moreover, the strategy to copy them mechanically in Georgia can seriously endanger the process of development of this field. Finally, it is concluded that the concept of the reform of education and science should be mainly based on the European model together with rich experience accumulated in the country, native customs and traditions, financial opportunities and other specific circumstances and peculiarities.

There is a view on inevitability of uniting science, education and scientific-technological progress (STP) in knowledge-base economy (but there also is one remark: further development of STP in Georgia is now impossible due to the lack of necessary funds). Since the 21st century science has partly united with education in the post-soviet Georgia. In 1995-2005, the number of scientific workers declined dramatically. As the revealing of potential in this field has become increasingly difficult and fewer funds are assigned by the state, we are facing a massive brain-drain. Other problems to mention are the closure of many educational institutions, low salaries, etc. Georgian entrepreneurs have no funds for financing scientific researches. The formation of a self-organizing economic system for science and education is seen as a way out from this impasse. Ref. 6.

Globalization means unification, getting together. It has no borders and to a certain extent means to regulate life in a new manner. The process of globalization goes very quickly in the educational system of Georgia. Whatever attractive it may be, the blind and exact copying of it is inadmissible. We are not against the introduction of novelties in the system of education, but they should be based on the national ground, our centuries-old culture; national originality should be preserved in the Georgian school and not be endangered.

Reflexion is a deep recollection of a student’s activities, including the past actions. The finding of the ways for organizing a learning process, solving the problems, analyzing the results and determining the future tasks depend on it. Out of the factors affecting the quality of reflexion mention should be made of the heterogeneity of their forms which are related to age, individual and other characteristics. Also, in the process of reflexion, the method of psychological approach has to be pointed out. Therefore, reflexion is the period of emotional and mental condition, which helps her/him to realize the way and content of the whole process. A student accepts its results and can manage to set up even more difficult future tasks. Ref. 4.

In the teaching process of a foreign language the important role is given to communication skills development and the target language learner’s active involvement in the learning process. A method of working on the project creates alternative conditions for further strengthening the linguistic competence. The learner’s interests are fully taken into consideration in the project. Within the cooperation he/she himself acts as the author of the idea, plans and manages every step. The project method is the way to get knowledge creatively, starting on initiative and in a limited time, and ending with the presentation of the product. During the whole process, its participants realize the linguistic potential in a new intercultural-communicative situation. Ref. 3.

Teaching belongs to the group of professions whose object is a person. Its primary goal is human relationship. Teachers aim at forming and transforming of individuals. They strive to direct their intellectual, emotional and physical development, affect their inner world. If a teacher does not have an adequate relationship with the people he/she supervises, it means that the most important part is missing from their work. On the other hand professions of this type always require special knowledge and skills in certain fields. Teachers, as well as school administrators must have a clear idea about the activities of pupils whose process of development they are responsible for. Thus, pedagogical profession requires two types of preparation – in the field of human studies and knowledge of specialist. Ref. 6.

Out of the problems of theoretical pedagogy, Uznadze was most interested in the issue of interrelation of pedagogy and psychology. The reason for this is obvious, since first of all Uznadze is a psychologist and every form of human activities, including teaching and learning, he considers from the psychological standpoint. He believes that scientific pedagogy can be based only on the knowledge of the child’s psychology. The point, according to which the pedagogy, both theoretical and practical, must be constructed on the psychological knowledge, as a red line follows his scientific work (works with pedagogical and pedagogical-psychological content) devoted to educational problems. It seems clear that at the different stages of the author’s general psychological concept evolution, the various aspects of links between pedagogy and psychology were very topical. At the same time, the argumentation for substantiation of the stated point was undergoing changes and strengthening as well, but the author’s main credo on crucial importance of psychological knowledge of educational work remained invariable at all stages.

Willpower plays a great role in a person’s self-education. According to the academician Dimitri Uznadze “the whole human personality is built on that”. The learner should show his willpower, first of all in his basic activity – studying. For some students this is more troublesome than doing physical activities. That's why willpower should be generated in learners from the early age which is the stable base of teaching and studying. First of all learner may aim to follow a day schedule than in case of turning it into a habit he should pass on generating more difficult features. While doing this, person should overcome indolence and self distrustfulness which becomes stimulus for a new determined behaviour. Ref. 6.

The article deals with the problem of teaching listening skills/strategies to learners. Listening strategies cannot be learned in a day or in a week. It should be included in everyday lessons. Teachers should see to it that students can activate listening strategies which they previously learned during a lesson, and scaffold their understanding of new listening strategy use. Students should have reflection on their listening strategy use during or after the lesson. So, effective and ideal language instructors should help the learners to be introduced with native speaking, to be respondent to that both cognitively and orally. This can be conducted in different modes such as group discussion, classroom discussion, reflection journal, and interview. Ref. 4.

 An automated system is designed for daily paid parking and temporary parking fixing the time of arrival, duration of parking and giving bills when leaving the camp. It is known that in the United States and in many European countries they use different methods, systems and equipment to control parking. Frequently they use special counters for payment. Our system is completely consistent with the charge parking and compatible to all the requirements and restrictions set by the dwelling of automated securities. The new automated system may be used in airports, railway stations, supermarkets, restaurants, stadiums, or other public places in different areas. The expected results of the use of the automated systems are: accurate paid parkings’ accounting, control and management of the parking systems. The owners of motor vehicles (drivers) will get service with improved protection of their vehicles provided by our system. Fig. 2, Ref. 3.

Nowadays, the internet service is widely used in many cities of Georgia. Consumers have higher demands. Service centers have to buy the growing capacities to satisfy the demands of customers, which is connected with additional expenses. As a result, the cost of service is higher for the customer. Competition stimulates the provider not to increase fees. Therefore, a strategy of effective repair and re-equipment of networks, which do not require additional costs, is needed. Given the above, a technique for evaluating engineering strategies for improving networks is to be developed. The issue of network management without expanding the network is of urgency. In this case providers should manage the network by means of data communication on the basis of internal algorithms. Therefore, the actual problem is to develop a technique of effective network design and solve the actual network problems by its means. Fig. 3, Ref. 6.

It is impossible to imagine the modern economically de­veloped society without stock-exchange activity. In ad­dition, today it is necessary to use information systems and technologies for efficient activity of stock markets. In this connection it should be noted that computeri­za­tion of stock markets must be provided in two directi­ons: usage of computer and network technologies and provision of information support. The given article des­cribed types of moder stock markets, there are discu­ssed stock, commodity and currency exchanges, their functions and tasks. Also in the given article there are presented main steps of stock markets activity. It is mentioned that proceeding from the steps of stock market activity an information system must consist of certain modules. This modules during their functioning must satisfy certain demands. In the article there are characterized subsystems of stock exchange informa­tion system: applications and reports forming subsys­tem, trade subsystem, payments-clearing and deposi­tory subsystems, information and Administrative-control subsystems. There are given their functions, tasks, con­nections with other subsystems and demands, which must be taken into account while designing these sub­systems. There are given main principles that sho­uld be followed during the procees of designing exch­ange information systems. Tab. 1, Fig. 1. Ref. 5.

Optimal methods to create a universal software package are an important scientific technical objective. In multidimensional optimization tasks a one-dimensional optimization method is used to select the step. We consider interesting to research effectiveness of the methods of gold section and the segment division into three equal parts to study an experimental error. We carried out study of the efficiency criterion and observed time indicators for searching the extremum. The experiment showed that the best use of the bidding step is to choose the method of division into three equal parts, which is much more efficient in case of experimental errors. It is also important for the effectiveness of the extremum point of the interval boundaries of the location. Ref. 2.

12.A5.16. Fuzzy expressions in knowledge represen­tation. /M. Kiknadze, A. Kobiashvili, M. Maghra­dze/. Basic Paradigms in Science and Technology Development for the 21st Century. Trans., Int. Sci. Conference. Tbilisi. 19-21 Jun. – 2012. – v.II. – pp. 306-309. – eng.; abs.: geo., eng.

One of the guidelines of fuzzy logics theory development lies in rep­re­sentation and handling of conceptual information. It is needed two stages for handling fuzzy data: To capture statements which contain fuzzy linguistic information; to prepare inference of new facts on the basis of preconditions and current state of the system. Both two stages take place in expert systems. The fundamental metho­do­logical problem is to select the correct control mode for handling uncer­ta­inty used in really existed expert systems. There are many approaches to research an in­ference which characterizes the human cognition and decisi­on-making. The concept of fuzzy systems is discussed as an alternative way for language information maintenance. One of the principal reasons of logging in application of methods of fuzzy sets is man-machine symbiosis. Any expert system must be able to explain deducible results, i.e. it should not only solve the assigned task about contents of knowledge but also inform the user about the behavior of its reasoning. Interaction between the system and user must be efficient to the maxi­mum. The question formulated for inference and issued from what is con­tai­n­ed in the data base, must be sufficient, and as completely correspond to human way of thinking with linguistic categories and not with exact nu­me­ri­cal values as possible. In the expert system assigned for aims of technical diagnosis, different versions of production rules are used. In the process of control production rules may have various interpreta­tions because of probability. They are formed due to representation of ope­rator's knowledge about given object domain. All the production rules are stored in knowledge base and are used to set up the hypothesis when the parts of pre-conditions are known. To output the hypothesis by means of proving process, a general and most frequently applied modus ponens is used. The scheme of infe­rence where uncertainty was connected with production rules is offered in which fuzzy expressions of hypothesis are calculated in according with a fuzzy equation. Ref. 5.

In spite of the fact that now the majority of documents exist in electronic form, the task of creation of completely electronic document management still represents serious problem. The task of moving of information from paper to electronic form is actual not only in systems of electronic document managements. For solution of this task it is necessary to create recognition systems for printed and handwritten texts. If recognition of the printed text is well studied task in the world and is successfully decided for many different types of a font, the task of recognition of handwritten texts still remains unresolved. Its final decision needs some more years. Unfortunately, for Georgian printed texts the problem of recognition is not decided yet, there are also so many difficulties for the handwritten texts. In this article are considered problems of preliminary computer processing and recognition of Georgian printed and handwritten texts. Fig. 5, Ref. 5.

Cyber-security is the concern of every country. Recent events have demonstrated once again that this is a particular challenge to Georgia. Georgia appeared not ready for cyber attacks on its information space performed in August 2008; Generally speaking, the identification and classification of threats and the study of their causes are not only topical, but, in our opinion, they are essential in the process of elaboration of protective measures and designing of protective devices and systems for information space security. At present there are various approaches to the assessment of threats. Different authors use different criteria for classification of threats, such as a type, a degree of malicious intent, a location and/or a cause of threat occurrence etc. By their origin the threats may be casual and intentional whereas the conditions of threat occurrence may be divided into two groups: objective and subjective. The sources of threats may be: People; Engineering facilities; Software, algorithms, models; Information proce­ssing technologies and the environment. The goal of realization of information security of some entity (a country, a region, an industry, a department etc.) by the system approach is the formation of the system providing the information security. For construction, it is essential: to define special requirements for protection of the given entity; to take into consideration national and international laws in this field; to draw on the available practical experience in creating such systems. The general, technical and organizational requirements, which are the components of information security policy, must be defined. Structural subdivisions responsible for realization of the information security system should be appointed from the outset, and the limits of their responsibilities should be defined. Appropriate algorithmic, program and technical methods and facilities should be used and implemented. The management system must be used in functioning of the information security system. Efficient monitoring of operation of the implemented system must be performed, and, if necessary, appropriate alternations and corrections should be made. From the above reasoning it is clear that the process of realization of the information security system is continuous and that it cyclically reverts to the first event after each alternation and correction. It should be emphasized that the country must have the national doctrine of country’s information security, which will make up the unity of legal-methodical documentation of the information security system together with National and International Standards, and methodical instructions and recommendations.

Machine translation from any language into Georgian requires composition of a word by indicating its unchanged part and morphological categories. Besides this, for distance studying of Georgian language and making assistant computer means for teaching the morphology of Georgian language to secondary school pupils, it is necessary, using unchanged part of given word, to obtain by the computer all grammatically right word-forms. For solving all these problems, we have developed the software, by which it is possible to solve mentioned problems. Besides this, for solving such problems of artificial intelligence, which requires composing of Georgian word-form by using the information defining this word-form, there can be used the software developed by us.

Automation of business management processes requ­ires creation of a distributed, multilevel system. For the design of the systems, similar to this configuration the unified modelling language (UML technology) and different CASE of means developed on its basis are used. For the system configuration modelling which should reflect both functional, and non-functional (technical) requirements, this technology uses the expansion chart. Nevertheless the entire process of design depends on the expert. Thus neither the designer nor we can determine how good result we have obtained. As far as the implementation of business – requirements is connected with a parallelism, and this process is described by the activity chart, transforming this chart in to columns of a network of Petri, gives a chance to model dynamic processes in a computer network. On the basis of analysis of these models the configuration of customer-server architecture corresponding to these requirements is under consideration. Ref. 3.

Hybrid intelligent systems are the object of studies. They integrate the advantages of autonomous approaches for solving complex practical problems. In recent years, traditional methods of artificial intelligence, such as expert systems, fuzzy systems, artificial neural networks, genetic algorithms, etc. are increasingly combined in hybrid intelligent systems. Hybrid intelligent systems can take advantage of traditional means of artificial intelligence, overcoming some of their shortcomings, and can solve problems unsolvable by individual methods of artificial intelligence.

Four specialized software packages for solving problems in managerial activities have been chosen. Each software package, besides general purpose, has its own functional goals and the list of practical examples. By means of the used approach software packages supplement each other and create a uniform complex for the decision of managerial problems. There is a functional interrelation between software packages. Output parameters of one of them can be used as input parameters for other ones. They have provided possibility of grouping problems of different complexity for different level of learners, including the fourth and fifth level of training, as well as bachelor and post-graduate students.

Information management, having appeared as a part of the theory of management, has quickly gained quite independent value and is considered as a perspective scientific trend in the information era. The information management concept comprises the following approa­ches: economic, considering questions of attraction of new documentary information, proceeding from reasons of utility and financial expenses; analytical, based on the analysis of needs of users in information and communications; organizational, considering information tech­nologies in their influence on organizational aspects; Information management in the organization carries out strategic, operative and administrative tasks. The main task of information management is informa­tion support with the use of modern information technologies (OLAP, OLTP, DWH, ORP, BI) primary activity of the organization. From this point of view it is necessary to see a problem of information management in integrating the individual information elements of system created by staff (documents, affairs, technologies) on the basis of the uniting program of search by the most important component of structure of information management.

We have studied a class of combinatorial models that are semantically close to a known One-Dimensional Bin Packing task. All models have a large number of practical applications in different fields. A general description of the class consists in dividing the initial set of weight into a number of disjoint subsets with the given properties, which are defined by using the model restrictions. Primary attention has been given to the estimation of quality of approximate solutions as a measure of closeness to the optimum solutions. With that purpose, we built the bounds of objective function, which the approximate solutions are compared with. To find the bounds, we use two blocks: a block to reduce the initial size of tasks and a block to build the estimation corridor of reasonable solutions. The first block removes the dominant groups of weights (the dominant pairs, triplets, quarters and so on) from the initial data. The second block estimates the existence of reasonable solutions for a given number of subsets. These blocks are closely interlinked. The results of the first block are used in the second block and vice versa. Our algorithms for finding the bounds can be used in practice for large-size tasks (the number of different weight may be 50,000 and more). Ref. 10.

12.A5.26. IPV6 protocol deployment and migration strategies for isp networks. / I. Kartvelishvili, O. Kar­tvelishvili/. Basic Paradigms in Science and Technology Development for the 21st Century. Trans., Int. Sci. Conference. Tbilisi. 19-21 Jun. – 2012. – v.I. – pp. 125-134. – geo.; abs.: geo., eng.

The present paper is aimed to provide some kind of roadmap to IPv6 migration process, which may become a real problem for ISP technical staff. As there are quite lots of options for IPv6 migration with their respective advantages and disadvantages, it may be quite difficult to plan the correct roadmap, which may suit the specific network requirements. This document provides some in-depth information regarding different techniques that may be used on intermediate stages of IPv6 deployment, their possible combinations, investigates how the migration process for ISP is organized and also provides several advises and guidelines about the migration stages based on author’s experience. At any rate the migration to IPv6 is subject to heavy preliminary testing in order to find the method(s), vendor and platforms the most suitable for each certain case. By design IPv6 protocol is not very complex, but the fact that it cannot be deployed overnight makes the main problem. It is obvious that there will be a time period when IPv4 and IPv6 will have to coexist and this is the point where the most complexity comes. Fig. 10, Ref. 9.

The article deals with the veiwpoints of Ilia II, the Catho­licos-Patriarch of All Georgia, about the varieties of the spiritual or national values of small nations that are of vital importance for the world. Georgia is important for the world not only with its strategic viewpoints but first of all with its spiritual and material values. The article also deals with Catholicos-Patriarch’s viewpoints being of world importance about the formation of common system of values to save the world that will act as a function of its moral axis. Also the dialogue between culture and religion should be achieved in the way that all nations would maintain its religion and to form and implement the common values for everyone. The for­mation of the state thought, reasonable solution of socioeconomic problems of society, formation of the Ge­orgian state based on modern technology and achievements, development of agriculture, small amd medium-sized businesses, even complete usage of scientific or economic achievements of Soviet Union, expansion of Georgian business sector, Creation of wealthy middle class, improvement of small and medi­um-sized business, production of ecologically pure products are considered as one of the most important value in the globalization period by Catholicos-Patriarch of All Georgia. The article also deals with the viewpoints of Catholicos-Patriarch of All Georgia about the man as the most importance value, and he considers that there are „three greatest holi­nesses: God, motherland and human“. And according to Catholicos-Patriarch of All Georgia, the most impor­tant condition is law, serving the truth and fairness. Ref. 4.

The opinions on the press expressed by Ilia Chavchavadze are still topical today, especially when analyzing global and national problem. Unfortunately, modern media lack this very important attitude. The incompetence of journalists still remains an unresolved problem, and in most cases, professional irresponsibility. This is what Ilia Chavchavadze was opposed to. Involvement of mass media in developing the democratic government requires much more objectiveness and higher qualification from journalists. The standards which were adopted by Ilia Chavchavadze and many other representatives of Georgian publicism are still valuable today. In the paper presented by us those opinions of Ilia Chavchavadze which should be considered in modern journalism are gathered and discussed.

In the article the role of social mood having a great value in contemporary social-economical processes is discussed. This is proved by a lot of experimental materials of researches done by Dimitry Uznadze in experimental and social psychology. The conclusion drawn by this research is as follows: formation and upbringing of a person as a psycho-social creature is made in the “humanized” environment on the basis of social mood due to which a man creates social and economical values and changes the existence. The article deals with the fact that non-market relations – moral, cultural – which exert an influence over the present processes not less than buy-sell relations are of vital importance for effective functioning of social-economic processes.

Paper deals with a novel paradigm of fundamental thinking – Systemosophy. The already existent systems approach of general systemology, based on materialistic viewpoints, describes the universe discretely, only one-sided projective, from its own viewpoints, whereas at the dawn of the twenty first century the modern science is lot more developed. The way to the unification of science, religion and philosophy lies in the radically new concept introduced into the scientific canon by quantum physics, because they are based on old traditional thinking and they have need for quantum renewals. So the transition from systemology to more modern consciousness is the main requirement of this time. Systemosophy as new systems of paradigm could present the universal approach, based on quantum philosophy, scientific and esoteric knowledge, to find true sense and function of human existence.

For this system, magnetic ordering is not characterized despite the fact that it shows the maximum  susceptibility  at  low temperature. The  analysis showed that at low temperature the magnetic spin-glass state is characterized of this system. It is shown that at the manganese concentration x=25% the spin-spin correlation peaks, which is caused by an increase in the density of the state of substitution of cobalt for manganese. Because of negative Mn-Mn exchange, they failed to stabilize the magnetic ordering in this system. The spin-glass state of this type, in which there are no stable magnetic moments in the paramagnetic phase, is classified among new-type “zonal” spin-glass states. Fig. 5, Ref. 5.

In the present paper the lattice of cosets is constructed for Hall’s power group G over the ring W. This lattice is called the affine or coset lattice of G. Since in the lattice only the elements of G cover Æ, the isomorphism defines the bijection . Among all possible isomorphisms ¦ we shall select in the sequel those for which. Such isomorphisms are called the affine isomorphisms. We prove the following theorem: Let be an affine isomorphism between the w-power groups G and G1 over the fields W and W1, respectively, if G is nilpotent of class 2 then¦ is either a semi-linear isomorphism or a semi-linear anti-isomorphism with respect to the isomorphism σ :W ®W1. The given example shows that the theorem is false for the class of nilpotency ≤ 3. Ref. 9.

The problem of soliton stability in the chiral sigma model is investigated. After the brief introductory relations the relevant expression for the Hamiltonian appropriate to the quantization of rotational and vibrational modes as well as the pion mass term is presented. Corresponding equation of motion is exhibited, from which the effective potential is extracted. The existence of minimum of this potential is established and the energy of the ground state is found. It is shown that stability may be achieved only after the breaking of chiral symmetry by pion mass term. The profile function is constructed which guarantees the stability. Mass spectra of nucleon and its resonances are derived. This is analogous to WKB quantization formula.

where expressions for entering here parameters are given in the main text, Eqs. (15). Unfortunately the profile functions applied do not satisfy to the equation of motion, therefore their status is unclear. Nevertheless the existence of minimum is a remarkable property for this problem and it underlines the importance of quantum consideration. Therefore it is interesting to calculate appropriate profile function. In this purpose the calculation scheme is proposed for the profile function in the Skyrme anzatz, which then may be applied to delta – nucleon transition problem. The most profound task is a reconstruction of the profile function from the integral relations. For the present only henomenological consideration shows that by choosing of appropriate test profile functions rather good description of nucleon resonance masses may be achieved. Ref. 6.

We consider the simplest theoretical model of scalar fields in one spatial dimension with an internal symmetry. We apply the Schrödinger picture to describe the quantum properties of localized solutions. The use of the method of collective coordinates allows to develop a perturbation theory, which exactly describes the symmetry properties of the theory. As an example, we consider the theory of three scalar fields with a broken SU(2) symmetry, for which we derive the dependence of the energy spectrum on a quantum number corresponding to a charge symmetry. The energy of quantum bound states is the classical energy plus the energy of quantum excitations. The result does not depend on the specific form of the interaction potential. Ref. 14.

12.B1.9. Azimuthal correlations between protons in the backward and forward hemispheres in nucleus-nucleus collisions at a momentum of 4.2 GeV/c per nucleon. /L. Chkhaidze, T. Jobava, L. Kharkhelauri/. Bulletin of Georgian National Academy of Sciences. 2012. – V.6. N3. pp.43-48. eng.; abs.: eng., geo.

Multiparticle azimuth correlations between protons have been investigated in (d, He)C,CC, (d,He)Ta and CTa collisions at a momentum of 4.2 GeV/c and “back-to-back” correlations have been observed. Essentially, correlation function C(Δφ) for and reaches maximum at Δφ =protons from these collisions increases with 1800 (the angle between the vector sums of the forward and backward emitted protons). The asymmetry coefficient | ξ | decreases and the strength of correlation ς increases with increase of the projectile and target mass numbers. The dependence of the mean of the square transverse momentum in the reaction plane <Px2> on Δφ shows similar behaviour for all observed interactions. The data stem from the propane bubble chamber (PBC-500) system utilized at JINR. The quark gluon string and the ultrarelativistic quantum molecular dynamics models satisfactorily describe the experimental results. Fig. 4, Tab. 1, Ref. 22.

Rostomashvili, Z. Saralid­ze/. Bulletin of Georgian National Academy of Sciences. 2012. – V.6. N3. pp.49-54. eng.; abs.: eng., geo.

The nuclear research reactor IRT-M belonged to the Institute of Physics and operated during the 1960-1988 period. All nuclear fuel (both fresh and spent) was sent out of Georgia after the reactor was shut down. The reactor decommission activity was conducted at different stages. Special activity plans were developed considering safety and security requirements, international experience and local circumstances. The developed decommissioning strategy was based on the idea on possible establishment of a new low power nuclear facility in the tank of the decommissioned reactor. At the first stage the reactor core together with some comparably high active waste was covered with special concrete. A special underwater concreting technology was developed for this purpose. Theoretical assessment of radiation was conducted before the activity. The results of theoretical assessment were in good correlation with data obtained at radiation monitoring during the concreting activity. During the second and third stages the reactor system inside and outside of the reactor building was dismantled. Lacking the capability to conduct full scale radioactive waste treatment, a special technology of waste packaging is developed to meet the safety requirements. The creation of a radioactive waste treatment facility was defined as a next stage of the activity. Ref. 5.

Statistical analysis was conducted (data of 1906-2009) on the change of near-surface air temperature field for various geographical regions of Georgia. The analysis was fulfilled by the dynamical norm method. Data of 89 points existing in 1906-1995 and 28 points in 1996-2009 were used. Restoration of missing observation data with given accuracy and reduction of the data series to the same period of time were carried out by the method of expansion of the random function in natural orthogonal components in multidimensional space. Natural variability of temperature anomalies, linear and nonlinear trends of the variability, density of space-time change probability are shown. Regional parameters corresponding to two periods of time are compared with each other. Schematic map of change of near-surface air temperature field on the territory of Georgia in 1906-2009 is given. Facts of fall of temperature on the territory of Western Georgia and significant warming in Eastern Georgia in 1906-1995 have been proved. The data of 1906-2009 on warming in all regions under study have also been proved; tendency of the increase of the global warming intensity over the last 10-15 years within the temperature range 0.2-0.5oC/100yr is shown. Maximal rate of temperature growth observed on the territory of Kvemo Kartli is defined. Results indicate increase of intensity of global warming on the whole territory of Georgia for last 10-15 years. Fig. 3, Ref. 10.

The analysis of some major tropical cyclones (TC) has been performed in the framework of the so-called model of equilibrium translation (MET) in order to eliminate the contradiction between the available field data and thermodynamic theory of maximum potential intensity (MPI). According to the MET, TC is an open dissipative system internally aimed at intensification. When this inner focus comes into a certain harmony with large-scale environmental wind, TC becomes particularly effective in the conversion of oceanic heat into kinetic energy of cyclonic motion and rapidly intensifies (alignment effect). Dimensionless Shekriladze number, incorporating integral thermal and dynamical parameters of the system ocean-cyclone-atmosphere (SOCA) acquires the role of a predictor of the character of TC development, including rapid intensification. The MET reveals negative feedback between hurricane heat potential (HHP) and TC translation speed during the alignment effect, leading to a constant mean sea surface temperature (SST) under acting TC, regardless of the initial HPP. In such circumstances, the constancy of real maximum intensities of TCs recorded in field observations at HHPs, exceeding 50 kJ×cm-2, is in agreement with the thermodynamic theory. In addition, the approximate analysis of the field data specified in the regular forecast advisories shows linkage of the alignment effect to the critical value of Shekriladze number around 35. However, this important outcome needs further confirmation by analysis of more detailed field data. Fig. 5, Tab. 1, Ref. 12.

The paper announces the boundedness criteria of majorants for b-order  Cesáro and Abel-Poisson means in weighted grand Lebesgue spaces  . It is claimed that in these spaces the mean continuity property fails to hold. The fractional order moduli of smoothness are introduced in a subspace of where the set of smooth functions is dense. Using these characteristics, direct and inverse inequalities of the constructive theory of functions are obtained. The rate of approximation by b-order Cesáro means is estimated for a function from the above-mentioned subspace. In weighted grand Lebesgue spaces, an analog of the well-known Bernstein inequality is established for the derivatives of trigonometric polynomials. Ref. 11.

Motivated by the famous Maxwell conjecture on the number of equilibria of point charges, we discuss the electrostatic potential of point charges placed at the vertices of polygonal linkage. In particular, we establish that electrostatic potential is a Morse function on the moduli space of a generic polygonal linkage, which yields estimates for the number of its equilibria. For quadrilateral linkage, we present a number of results on the structure of electrostatic equilibria and, as a by-product, prove that its shape is completely controllable by changing the charge at just one vertex.

Study of the structure behavior under microtremors to assess its real operating condition or to ascertain its dynamic characteristics is a widespread method in the world. It is distinguished for its cheapness, mobility, though it has also certain limitations. It is that transition process from microtremor to real is not univocal and relies on certain assumptions. Therefore, when we use this approach in practice, we are offered different algorithms and technologies of material processing obtained as the result of the experimental observation of the structure under microtremor, which creates probability of structure operational condition, particularly, its earthquake resis­ta­nce distinctive assessment. Mathematical model and algorithm constructed on its basis, which univocally ascertains how to process displacements recorded under mic­rotremors that to speak substantially about structure behavior when real seismic wave passes its foundation are suggested in the present article.

Among actual problems of the spin dynamics of superfluid 3He the anomalously fast (catastrophic) decay of coherently spin-precession mode is under active investigation. Experimentally this low-temperature phenomenon is observed in 3He-B. One of the possible mechanisms of the fast relaxation of the phase-coherent spin precession was attributed to the parametric instability realized in the background of a non-Leggett spin-orbital configuration of the Cooper condensate. An analogous process of the decay of coherent spin precession can be realized in 3He-A. The quantum description of this event is considered in some detail. Ref. 19.

The ground-state magnetic phase diagram of a two-leg spin ladder with trimerized modulated rung exchange is studied using the continuum-limit bosonization approach. In the limit where the rung exchange is dominant, the model is mapped onto the effective quantum sine-Gordon model with topological term. Six quantum phase transitions at different critical magnetic fields are identified. We have shown that the magnetization curve of the system exhibits two plateaus at magnetization equal to the 1/3 and 2/3 of the saturation value. The width of the plateaus is proportional to the excitation gap at given magnetization and scales as  , where  is the amplitude of rung exchange modulation and the critical exponent is obtained as V= 1.13 in the case of a ladder with antiferromagnetic legs and V= 1.50 in the case of ladder with ferromagnetic legs.

The results of an experimental study of the process of convective heat transfer in the vessel with stirrer for smooth and rough ring-shaped pipes are presented. In the experiments, were used as coolants distilled water and transformer oil. Experimentally were found three regimes of the influence of artificial roughness on the convective heat transfer: 1) regime, where roughness has no influence on heat transfer; 2) regime of partial influence of roughness on heat transfer; 3) fully developed roughness effect regime. It was established that creation of two-dimensional artificial roughness on the heated surface causes the essential (~90%) intensification of convective heat transfer in case of fully developed roughness effect regime. The similitude equation for calculating convective heat transfer coefficient, which generalizes well experimental data both for the smooth and the rough surfaces is proposed. Fig. 2, Ref. 8.

The paper studies the application of torsion centre for the open profile thin – walled bar wrap. They in turn cause emergence of secondary tangents of stresses. At constrained torsions in such cores maximum secondary tangents of stresses arise exactly there where they are limited and the external torque entirely comes on these stresses. As the expected dangerous condition comes in these sections from big secondary tangents of stresses calculations must be carried out in a plastic stage with stresses. Calculation is carried out by a method of variable elastic parameters. Fig. 4, Ref. 3.

To solve fundamental and applied problems especially at the junction of several sciences, such as molecular biophysics, bio-nano-physics, medical physics, etc., a complex approach is needed [1, 2]. E.g. for solving the problems connected with bio-nano-photonics and medical optics there appear some problems connected not only with the processes of photo-induction taking place in bio-molecules and cells but to the dark processes in live cells at photo-chemo- and photo-thermo-therapy. The approach to such problems often needs not only spectroscopic methods of investigation but also application of hydro-dynamic methods (viscosimetry, electrophoresis, chromatography, etc.). The goal of the presented contribution is the demonstration of possibility of multifunctional compact precision mobile system which does not need substantial financial and energy charges (most of the study can be carried out using a car battery). The main priority of the system is that the solution of a lot of complex bio- and medical problems can be achieved by exclusively optical methods. The universal optical system created in Andronikashvili Institute of Physics at Ivane Javakhishvili Tbilisi State University is able to conduct the following researches in real time: spectra-photometric, spectra -fluorimetric, multi-angular light scattering and radiation temperature measuring. The system also allows to conduct photo-irradiation in visible light spectra, including semi-conductor laser irradiation (λ=457nm); VHF and microwave irradiation; simultaneous spectroscopic measurements of both photo and VHF irradiation at various temperatures. We should point out that the optical system is possible to conduct multi-element glow discharge atomic emission spectral analysis using VHF ICP reduced pressure. Fig. 7, Ref. 8.

The work studies a solution of problems of optimum control systems by means of E. Neter's theorem, which establishes a connection between symmetry and preservation laws. The problem of controlling the spacecraft movement for keeping it in the vicinity of the libration point is described. Two problems of optimum control: variation tasks and the principle of a maximum of Pontriagin are considered. Using E. Neter’s theorem, mathematical equations linking the functions of optimum control and the laws of presentation are suggested. the problems of control with consideration of the restrictions expanding to both the functions of control and the phase coordinates are considered. We consider the relation between Pontriagin maximum principle and Lax’s method. The method allows us to resent Hamilton equation in the form of Lax equation. Lax’s method enables us to relate the conservation laws of Korteweg-de Vries equation with optimal control. Ref. 8.

The article is devoted to the determination of moments of inertia reduced to the initial links as well as definition of forces acting on the links of five bar mechanism with two degrees of freedom. The solution of the said problem is based on the usage of homogenous coordinates where a set of couplers of curves is obtained. Due to the equations of trajectories, the angles of rotation of actuators mounted into two input links’ rotating joints placed on the support of the mechanism are obtained. Here, in the given transaction, the calculations of the forces and torques acting on five link mechanical systems with two degrees of freedom are based on previous investigations, where had been derived the equations for the determination of equations for calculating values of speed and accelerating the links of the mechanism. It is necessary to note that the calculations of the values of force factors given here are different from the known methods, which are distinguished with simplicity and high performance as well as extremely useful for programming controllable actuators implemented in the joints of the linkage.

The article covers a hydraulic unit frequency regulator utilizing ballast resistors. In the regulation process, two control contours participate simultaneously – discrete and continuous. In the discrete control contour the commutation of ballast resistors is implemented according to the power load per user. Continuous control contour is managed by frequency errors and its first derivative. In the frequency control, there are used two second-order active band-pass filters. The first filter is assembled on the resonant frequency 40 Hz; and the second one – on the frequency of 60 Hz. The structure and characteristics of these filters are selected so that when ¦0 = 50 Hz, D¦= 0. The scheme has quite high sensitivity to frequency fluctuation: 0.5 volts on 1 Hz deviation. In the discrete control scheme there is also provided one additional “movable” ballast, which significantly improves the dynamics of regulation. In the continuous control contour, the ballast resistor contains the resistors, similar to the weight coefficient, which is controlled by reverse counter (integrator). In the regulation scheme there is provided launching and stopping of the hydro aggregate. Fig. 4, Ref. 4.

12.B1.31. Pumping effect of growing bubble: to over­come decades of neglect and silencing. /I. She­k­ri­ladze, G. Gigineishvili, J. Rusishvili, E. Machavariani, D. Shekriladze, L. Ezugbaia/. Basic paradigms in science and technology development for the 21st Century. Trans., Int. Sci. Conference. Tbilisi. 19-21 Jun. – 2012. – v.I. – pp. 248-257. – eng.; abs.: eng., geo.

The paper describes the controversial story of discovery and longstanding neglect and silencing of the physical phenomenon which plays key role in boiling heat transfer and hydrodynamics, as well as the ways to overcome existing abnormal situation. The case concerns so-called pumping effect of growing bubble (PEGB) that was forecasted in 1966. The PEGB has served as a basis for the new physical model (the model of “the theatre of director” (MTD)) which describes developed boiling heat transfer of all classes of liquids and defined the main line of boiling heat transfer enhancement. In addition, the PEGB can play a potentially important role of in the boiling crisis and hydrodynamics in some important boiling systems (microgravity, channel flows, liquid metals). The problem of PEGB-generated high-frequ­ency cyclic thermal stresses in heating surfaces, important in terms of reliability of nuclear power plants, also has been identified. At the same time, despite the interest in the initial stage of the research (the first article on the PEGB was translated and published by the NASA in 1967) and further comprehensive international publications, these boiling heat transfer fundamentals have been fully ignored for nearly half a century. The perennial criticism of I.G. Shekriladze and coworkers in leading journals and international conferences has never met objections. Despite de-facto recognition of superiority of the above fundamentals ​​by some recognized authorities, heat transfer community still avoids all possible forms of debates on the problem. Strong, but unplanned accidental manifestations of the PEGB in experimental studies almost always are misinterpreted and the effect and its potentially important consequences still remain poorly studied. Among the latter it is of particular importance a specific type of thermal fatigue associated with the PEGB-generated high-frequency cyclic thermal stresses in the heating surface. Lack of knowledge of these thermal stresses prevents complete theoretical determination of the operational resource of boiling water reactor (BWR) (including those at Chernobyl and Fukushima). In the paper, the first stage of solution of this problem is outlined through experimental investigation of PEGB during boiling of water in the wide range of saturation pressure in the experimental assembles of different geometry, including the conditions characteristic for boiling in BWR. Theoretical assessment of thermal stresses and thermal fatigue related to the experimentally studied temperature pulsations should be performed as well. Fig. 7, Ref. 31.

The present work deals with refining and regeneration of used motor oils for its reapplication with the same purpose. Initially the mixture of the used motor oils was treated by physical and chemical methods. Then the treated mass was distilled several times under vacuum, successively, at various conditions at 40, 10 and 1 mm mercury column residual pressures. Additives, in the following amounts: OLOA – 4594 CA” – 12%, “OLOA – 19803” – 0,3% and “PPARATONE – 8900” – 0,8%,were added to the obtained regenerated oil, in the preliminarily defined optimal conditions. As a result, on the basis of the regenerated oil the commodity motor oil was obtained. Modern instrumental methods were used to determine characteristics of the used regenerated commodity motor oil, including durability at metal tear and wear at axial charge, limits of welding and forging were defined. Welding was fixed at 299 kg, while forging – at 315 kg loading. Simultaneously, we prepared petroleum commodity motor oil on the basis of basic oil obtained from petroleum. Characteristics of the used regenerated commodity motor oil were compared to the very petroleum commodity motor oils with additive. Commodity motor oil produced from petroleum is characterized by lower welding and forging limit indices: welding limit was fixed at 282 kg, while forging limit was fixed at 297 kg loading. In the process of investigation the regime and technological scheme of cleaning and regeneration of the used motor oils were developed. Tab. 8, Ref. 5.

In this research, the problem of expression is studied using equations of continuity of deformation of the body based on the concept of dependence between the relative strains and stresses. In the classical theory of elasticity the gene­ralized Hooke's law is applied which does not fully take into account the correspondence between the stresses and strains not complied with the boundary conditions. These discrepancies are reflected in the magnitude of the shear modulus. In this paper we use the full voltage, the new value of the shear modulus and is a new form of the equation of deformation.

Two developed iterative algorithms for solving high-dimensional linear prog­ramming problems are proposed: the first one is based on the gravitation centers method, and the second one is realized on the basis of the constant step gradient method. Though the developed iterative algorithms are approximate, it is rather worth-while in most cases to apply them, when solving high-dimensional linear problems, as they are characterized by positive properties, such as simplicity of the algorithm and the program, high-speed performance and besides, the most important is the fact, that the appropriate software is free of such an unpleasant, specific for simplex method event as a “loop”.

We study mobile communication of networks, the AD-HOC networks, has attracted significant attention due to its challenging research problems. Ad-hoc networks are complex distributed systems that consist of a wireless mobile or static node that can freely and dynamically self-organize. We have shown the behavior of the relay buffer of the two-hop relay routing in mobile ad hoc networks by developing a queuing model. The parameters of the queuing model depend on the node mobility pattern. The main finding is that the expected relay buffer size depends on the expectation and the variance of the nodes contact time. Such analysis is done for the one dimensional random walk over a circle. Fig. 3, Ref. 5.

Usually, at the time of the biometric recognition are used either a verification method or an identification method. The article proposes a comparative analysis of their rate (throughput), reliability and ergonomics. The following conclusion is made: the identification method is characterized by high conductivity and ergonomics and the verification method is characterized by high reliability. There is offered an approach, when the verification and identification methods are concurrently used in the system, enabling to preserve these three parameters at the acceptable level. Discussed is an adaptive algorithm, when the system itself transfers from the identification method to the verification method and vice versa to increase reliability. Fig. 3, Ref. 5.

Tbilisi. 19-21 Jun. – 2012. – v.II. – pp. 266-276. – eng.; abs.: geo., eng.

Different long-term acoustic memory and magnetoacoustic effects were observed in magnetostrictive materials at their inductive excitation by radiofrequency (RF) and magnetic pulses using pulsed NMR and magnetic video-pulse excitation techniques. Along it the stimulated domain-acoustic echo, possessing a long-term acoustic memory was inductively excited by three RF pulses in magnetite and magnetoelectric ferrite-piezoelectric layered composites using pulsed NMR technique with inductive and electric recording of DAE signals. In this work we present also the results of comparative study of different magnetoacoustic responses on excitation by a series of RF and magnetic pulses using pulsed NMR and magnetic video-pulse excitation techniques in some magnetostrictive and magnetoelectric materials, in particular, magnetite, magnetoelectric ferrite-piezoelectric layered composites and magnetic bioceramic composite materials interesting for practical applications in biomedicine. In particular, the magnetic video-pulse excitation technique provides a comparatively simple method for wide-band characterization of these materials. Fig.11, Ref. 17.

Technology of preparing of praseodymium diantimonide crystalline thin films was developed on dif­ferent substrates (silicon, polycrystalline pyroceramic, sapphire) by vacuum-thermal evaporation from independent sources of components. There is shown, that the temperature of the evaporator of antimony influences coloring of the prepared films (golden, black, dark blue). The assumption is that coloring of films depends on valence of ion praseodymium in it. By the technique of full grinding the relative mechanical strength of the films has been studied. It has been shown that the mechanical strength under various conditions depends on the substrate material; in particular, it is increased successively according to the substrate material, monocrystalline silicon, polycrystalline pyroceramic, sapphire.

The 20th century is characterized by amazing intensity of physics development. It is difficult to consider physics as a whole from semantic viewpoint. A lot of theories have appeared to explain various problems. However the idea about final solution of the creation of universe became real. Gradually it became obvious, that every paradigm brings new problems, because new revolutionary theory functions as a new organ of sense. These new problems will exist at the radically different depth level. The article briefly shows the problems facing basic theories and concepts of modern physics. One might say that physics is at the deadlock. The only reliable way, to solve physics problems is experiment. That’s why that Large Hadron Collider gives us special hopes. Experiments which are held on Collider will solve problems like existence of Higgs particle, missing dark energy, etc. Most important is that these experiments will answer the question: is physics developing in the right direction, or all its steps indicate our ignorance by Socrates’ interpretation.

Using high-performance liquid chromatography were qualitatively and quantitatively identified high fatty acids contained in grape seed oil and compare its biological activity as 1.0% and 2.5% food-additive an fatty acids composition contained in lipids of mice livers. Investigation were carried out on 90 inbred mice, 5.0 g weight. Using high-performance liquid chromatography methods, grape seed oil was found to contain linoleic (65.0%), linolenic (1.5%), oleic (17.0%), palmitic (8.0%), stearic (4.4%) and arachidonic (0.6%) acids. After 15 days fatty acids are carried out from mouse liver and individually identified. The paper shows that 1.0% and 2.5% grape seed oil food-additives have a different biological activity. The investigation demonstrated that after 15 days the grape seed oil played a significant part in lipid metabolism of biologically necessary components.

Introduction and propagation of plants are considered to be one of the most important problems in plant biology. Successful introduction of plants depends on the conservation of the reproduction ability of plants in the new environmental conditions. During acclimatization of plants inner biological processes transform with respect to the new environmental conditions, such as soil and climate. Introduction and adaptation of plants is a complex and long process. Knowledge of the native habitat of plants, their transfer to a new area and propagation is not enough for introduction of alien species. It is necessary to conduct multi-year observation to determine the degree of habitation of some introduced specimens. In the present work the factors conditioning successful introduction of new species at the Ajara seaside are studied, prediction of the adaptation of alien plants under changed environmental conditions is made and the general mechanisms of introduction are determined. In the humid subtropical zone of Ajara a fairly large group of aliens is distinguished for fast growth, high productivity and aesthetic value. They reveal a fairly high potential which is one of the significant factors of successful introduction. Tab. 2, Ref. 5.

CeH2+c-type ordering hydrides are considered. Different ingredients of the total heat capacity C(T) of these ordering interstitial alloys are calculated and the summary result is compared with the corresponding experimental data. Metal-hydrogen interstitial alloys (M-H compounds) are considered usually as consisting of thermodynamically sufficiently independent following main subsystems: the lattice of metal atoms, the set of interstitial light atoms located in tetrahedral interstitial positions (tetra-positions) and octahedral interstitial positions (octa-positions), and the system of conduction electrons. It has to be taken into account that in superstoichiometric rare-earth dihydrides the subsystem of additional light atoms distributed on the set of octa-positions reveals a tendency to form ordered spatial configurations, which is associated with corresponding changes of the internal energy of light atoms. Generally, in rare-earth hydrides we have to consider as well the subsystem of local magnetic moments associated with metal ions, but in the hydrogen-rich cerium hydride magnetic interactions in the lattice we assume to be negligibly small. In such conditions the measured heat capacity C(T) of the given M-H compound consists of the following main components: a) heat capacity caused by acoustic waves in the metal lattice, b) heat capacity caused by local vibrations of light interstitial atoms in tetra- and octa-interstitial positions (characterized by different local frequencies), c) heat capacity related to the ordering processes in the subsystem of octa-hydrogen atoms, and d) heat capacity induced by conduction electrons. Basing on the standard mathematic expressions for the heat capacity ingredients mentioned above and using the set of energy constants defined in our previous article, an excellent coincidence between the calculated and measured C(T) dependencies is obtained in a wide temperature range.

12.B2.4. Dynamic mechanical properties of boron-doped monocrystalline germanium. /G. Chubinidze, I. Kurashvili, G. Bokuchava, Z. Chachkhiani, G. Dar­savelidze/. Bulletin of Georgian National Academy of Sciences. 2012. V.6. –N2. pp. 89-93. eng.; abs.: eng., geo.

Microstructure, electrophysical properties and characteristics of dynamical shear modulus and microplastic deformation of boron-doped monocrystalline germanium were investigated. Bulk crystals of germanium were obtained by Czochralski method in [111] crystallographic direction. Boron concentration in monocrystals was changed in the 5·1016-5·1019cm-3 interval. Dislocation density determined by estimation of the quantity of etching pits was changed from 103 to 5·104cm-2. It has been established that an increase of boron concentration in monocrystalline germanium causes a decrease of current carriers mobility and an increase of the absolute value of shear modulus in comparison with undoped specimens. After high temperature annealing tendency to increasing of current carrier mobility, dynamical shear modulus and elastic limit was revealed. By investigations of internal friction and dynamical shear modulus amplitude dependences of boron-doped monocrystalline germanium the following results were received. The values of elastic limit, dynamical shear modulus and critical strain amplitude of Ge:B monocrystals were determined. It has been established that weakly boron-doped monocrystalline germanium is characterized by high elastic limit, critical strain amplitude and shear modulus. This is due to structure strengthening, caused by an increase of dislocation blocking by boron atoms. In the case of high concentration of boron simultaneously with the strengthening process, “softening” process has taken place. It is determined by fulfillment of broken electron bonds near to dislocation cores that has caused decrease of activation energy of dislocation motion. On the basis of changes of interaction nature of dislocations and boron atoms mechanisms of strengthening and softening processes of structure under the influence of boron were analyzed.

Short-stemmed super dwarf wheat “Gorda” is obtained via treating seeds of the French-bred winter variety “Ducat” (released for distribution in Georgia) by 0.01% solution of chemical mutagene NMU – nitrosome­thylurea. “Gorda” is a mutant form of winter wheat. The plant is bunch forming with reduced numbers and lengths of internodes and its maximal height is 26-27 cm. The leaves are broad and erect. The stems are short, firm and they hardly bend. The spikes are awnless, short (4-5 cm), flat and dense, in which grown underdeveloped florets are densely arranged on the spike rachis. The glumes of the spikelet are convex. “Gorda” is a late variety for as many as 10-12 days as compared to the regular local check varieties. It is susceptible to leaf rust and powdery mildew. Grain is shriveled and therefore the mass of its thousand kernels does not exceed 30 g. Grain raw gluten content is about 27-28%. “Gorda” represents breeding material of new inheriting property, which can be used as initial material for developing shortstemmed varieties with 2-3 height reducing genes.

Based on the numerous cases of poisoning the population caused by excessive use of nitrate fertilizers and various chemicals, scientists decided to draw attention to the seriousness of the problem and inform the society about the importance of implementing vermitechnology to get ecologically pure and safe bio products. The vermitechnology and vermiculture is at least a century old but it is now being revived worldwide with diverse ecological objectives such as waste management, soil detoxification and regeneration and sustainable agriculture. Earthworms act in the soil as aerators, grinders, crushers, chemical degraders and biological stimulators. Earthworms secrete enzymes, proteases, lipases, amylases, celluloses and chitins in their digestive tract that make rapid biochemical transformations of cells and protein-containing compounds into such organic compounds, which restore and enrich soils. Earthworms dramatically alter soil structure, water movement, nutrient dynamics, and plant growth. They are not essential to all healthy soil systems, but their presence is usually an indicator of a healthy system. Earthworms perform several beneficial functions. All this will make it possible to start a continuous production of bio humus in «conscious" peasants’ farms and its intensive usage Furthermore, the high-efficiency natural organic fertilizer obtained with earthworms’ help is a warranty of a good harvest and provides ecologically pure product.

Using nano-tubular boron in nano-technology has an advantage over that of nano-tubular carbon because of possibility to control the chirality mainly determining physical properties of the nano-tubular material. There are available a number of technological applications for all-boron nano-tubes – metallic wiring in nano-electronics, protection against neutron irradiation and accompanying gamma-irradiation, etc. The analytic geometric model previously developed for boron nano-tubes with perfectly 6-co-ordinated chemical bonds ere extended to degenerate forms with reduced numbers of bonds between neighboring boron atoms. Based on this model, geometric parameters of some ultra-small-diameter nano-tubes are estimated. Degenerated forms of all-boron nano-tubes together can form ultra-nano-scale fibers, in which lacking bonds are restored.

Using Auger electron spectroscopy we have studied chemical compositions of GaAs(001) surfaces subjected to wet chemical treatment in hydrazine-sulfide solutions. It was found that the treatment produces a surfa­ce nitridation and forms continuous GaN films of monolayer thickness on the both surfaces. Due to high stability of the Ga-N bonds the nitride films are thermally and chemically stable and can be used for surface passiva­tion. The chemical nitridation of GaAs(001) substrates produces a marked improvement of ideality factors of Au/GaAs Schottky structures and decreases strongly a spread of their I-V characteristics.

On the basis of litho-facies analysis of Mesozoic deposits that accumulated during the development of orogenies (phases of folding), the processes of sedimentation accompanying these phases of folding as well as some paleogeographic and structural changes have been considered. Each phase of folding was accompanied mainly by synorogenic regressive formations. They were a direct consequence and criterion of manifestation of the tectonic movements. The most important among the manifested orogenies in the considered territory in the Mesozoic was the Chegem orogeny. It formed the main morphostructural units and mostly predetermined the character and appearance of present-day structure of the region. With due regard to the age of regressive deposits and geochronological data the first attempt to determine the duration of each orogeny was made. As to the Cenozoic orogenies, they will be discussed in a separate article of the same journal. Fig. 2, Ref. 35.

 For the purpose of regional prognosis of sudden outburst of sandstones and gas, the authors have analyzed ten factors: genetic types of sandstones, coal mark, depth from the surface, porosity of sandstones, quality of filling in of pores with gas, border of durability of sandstones pressing and stretching, elasticity module, methane content and gas pressure. Comparison of the appropriate rank indicators makes it clear that there exists a danger of sudden outburst of sandstones and gas field deep horizons. There has been made a preliminary conclusion that siltstone represents a danger of sudden throwing of gas and rock along with the sandstones. Tab. 3, Ref. 16.

The analysis of mining-and-geological and mining conditions of a mine working at the Chiatura Manganese Deposit shows that the methods of determination of parameters of conditions in regard to the manganese mines do not promote the fullest utilization of their reserves. Proceeding from the structure of the manganese series and from the presence of the clear borders between the ore interlayers and the dead rock, it is necessary and enough to determine the minimal industrial content of the useful component in the manganese ores for contouring of balance reserves. The practice of determination of the dimension of minimal thickness of the non-conditional interlayer of the dead rock in the contour of the whole stratum of the deposit without taking into account of the parameters of mining and the content of the useful component in the balance resources might result in either unprofitable development or unjustified waste of manganese ores. In process of development of the manganese stratum the minimal content of useful component in the balance reserves varies from 12 to 14% and from 14 to 16% on the slopes. Fig. 2, Tab. 2, Ref. 2.

The question of influence of worked out fields on ecosystem of Shaori reservoirs is considered. Deep cracks with width of 10-15 cm, landslides, situated on Earth surface building’s deformation within the range Nakerala and it is elopes are fixed, in general throated to ecosystems of Shaori reservoir. Therefore it is expedient and necessary to study the influence of worked out fields on the ecosystems of environment. The results carried out by VNIMI investigations are considered also. These results are ineffective for Tkibuli-Shaori deposit’s conditions. It follows that it is necessary and appropriate to carry out investigations of strained-deformation condition of rocks above the developed fields of Tkibuli-Shaori deposit. Fig. 1, Ref. 3.

In the article the most well-known methods of tunneling have been described: the so-called New Austrian Method (NATM) and the Observational method, as well as their application and differences. The NATM method uses all the means and methods of construction of underground structures, but it is mainly characterized by the widespread use of the control and measuring apparatus and monitoring. The normative documents and the literature provide some very important comments and recommendations, non-observance of which negates the effectiveness of use of control measurements. The Observational method of tunnel construction can contain some components of NATM, but the instrumental control and monitoring are not used or are of little importance. Some criteria that characterize this method are given. Ref. 6.

The expert results of the hydraulic calculation for the Baku-Tbilisi-Erzurum gas pipeline on Tbilisi territory are discussed in the assay. Expert calculations are done according to the demands of the former Soviet Union (now Russian Federation) and USA engineer-mechanists normative documents. According to the calculations, it is proved that today maximum actual capacity of gas pipeline for transported natural gas is very low and non-rational (K=0,172), which is completely economically unjustified. It is possible to increase the volume of transported natural gas, according to the pipeline diameter and pressure developed by the existing compressor and pressure lowering stations, which stipulates significant improvement of the entire system and technical-economical performance.

The work discusses the main results and the simplest modern methods of searching the stableness of stone material, as well as characteristics of elasticity of stone materials, which are determined by peculiarities of their composition. The majority of tests are done in the terms of one-axis pressing, as today the indexes of pressing tests determine the characteristics of stableness of the stone materials. As a result of the test, it is established that when examining the stableness of the stone material, the form and size of the samples are important. The absolute sizes of the samples significantly influence the stableness index. It is established that stableness is increased with increasing the sizes of the samples. Fig. 6, Tab. 1, Ref. 12.

The distributed anticipatory restratification concept (DARC) points the way to prevent severe convective storm. DARC provides artificial discharge instability energy of moist unstable lower atmosphere by convective clouds proactively forced in the area to be protected. The paper discusses some problems associated with the implementation of distributed proactive forcing (DPF) (the previous scheme of DARC). It is shown that the so-called meteotron, previously developed as a technical means to increase rainfall in arid areas, can be much more effective through the realization of DARC in a moist unstable lower atmosphere close to the development of severe convective storm. As follows from the simplified analysis, the required trust of the meteotron and its single run time strongly depend on the distance up to the bottom of capping inversion, the other conditions being equal. This puts to the fore the implementation of the schemes with location of meteotrons on mountain tops and in the marine environment. On this basis the new scheme of imported proactive forcing (IPF) is proposed. The potential applications of IPF for preventing hailstorms in the Alazani Valley (with location of the meteotrons on the mountain tops) and excessive rains in Ajara (with location of the meteotrons in the marine environment) are considered. The potential of DARC to prevent the development of severe tornadoes is outlined. The evaluation is made showing that the main conclusion of simplified analysis of the strong dependence of the main operating parameters on the distance up to the capping inversion will remain in force after a thorough analysis of the problem as well.

Development of atomic power engineering with nuclear fuel cycle brings forward the requirement of the condition control of the spent nuclear fuel (SNF). First of all, these are burnup, isotope structure of nuclear materials and fission products, data on the condition of shells of fuel elements, etc. It should be noted that detailed analysis of the specified parameters is important at all stages of the nuclear fuel life cycle at the nuclear power plant and in general at plant independently of the reactor type. Various aspects of increasing the safety of nuclear plants working on thermal neutrons are discussed. A new method based on application of Cherenkov effect and optical fiber for measurement of the nuclear radiation power, identification of the spent fuel assemblies and determination of the burning factor of the nuclear fuel is considered. Knowledge of burnup depth and isotope structure is necessary for elaboration of recycling strategy or burial of radioactive wastes. It is also important to reliably identify the spent fuel assemblies (SFA) to exclude the possibility of leak of the SNF, which may be used for manufacturing weapons of mass destruction.

This study relates to research, which will give us an opportunity to use solar energy photoelectric transformers more effectively. In particular, the research was carried out on the energy emitted by the photo element when it is effected by solar energy. If we use this energy for useful work (to heat the water), one can say that photo element effected by solar energy emits simultaneously two types of energy - electric and thermal. This means that useful coefficient is calculated by total work made by these two types of energy. The study was made on 1 cm2 area Ga-As photo element, cooled by water. The Research showed that optimal value of electric and heat energy emitted by it was at 450C temperature. In this case the efficiency increased by 47%. Tab. 2, Fig. 1, Ref. 2.

Forests have multipurpose social, environmental and economic functions (including climate formation, water regulation, soil protection, sanitary and hygienic, resort and recreation functions, etc.). Non-proper regulation of forests can lead the country to an environmental disaster. One of the major reasons for non-rational and illegal cutting of the firewood resources in Georgia is primitive consumption of firewood that is caused by low efficiency of the woodstoves which are able to use 30-40% of energy potential of the firewood. Even in case of increase of energy efficiency (efficiency factor) from 40% to 60% each family can save approximately 3,5 m3 firewood annually that makes 1,6 mln m3 in the country. Wide scale implementation of energy efficient wood stoves in the regions of Georgia has to be preceded by elaboration of a methodology for defining their energy efficiency   and  thermal   calculations,  solution of major calculation formulas, stating physical essence of the parameters of firewood and characteristic parameters of household woodstoves and correction factor, conduction of analysis of results of calculations, etc. All these require effort and time. That is why creation of computer calculation model, working out algorithms and their development and implementation by means of Excel table processor and programming language Visual Basic for Applications, will give chance for speeding up the calcula­tions and improvement of accuracy of the received results.

The main assumption of the paper is that the quantity of the so-called velocity pulsations at any fixed point in the turbulent environment is an integer-valued random process with independent increments (the Poisson Process), that can be broken down into two Poisson processes. The trajectories of the “insignificant” pulsa­tions are described by the stochastic integral from the Wiener process, while the stochastic integral from the significant” pulsations corresponding Poisson process produces a new process with independent increments. By the stochastic integral from this process we receive the value of the velocity at a given point of the trajectory at a fixed time. That enables us to write the equation of the trajectory. Ref. 7.

Recognition using neural network for determining the number of neurons for each pattern which provides error-free recognition of training set is discussed. It is known that the number of neurons in the layers of the modern neural networks used for recognition is determined on the basis of experiments, without theoretical justification, according to the heuristic considerations. In the presented paper a procedure for determining the number of neurons in the layers based on clustering is proposed. In addition, formal neuron’s recognizing function – "scalar product" as similarity measure for clustering is used. It provides a high level of clustering and recognition identity. On the first stage the number of neurons is determined for only one pattern. At the next stage the correction of the number of neurons takes place taking into consideration other system descriptions (templates). Fig. 1, Ref. 3.

The results of investigation carried out in the sphere of receiving of boron-free and fluorine-free primers of enamel are presented. For receiving of fluorine-free enamel the complex raw materials were used: glass breakage (GB) and magnesium-poor carbonate ore (CO). In order to state their quantity in boron-free and fluorine-free primers GB-CO-N2O were studied in the region of glass formation in pseudo three-dimensional system. It is stated that in the mentioned system there are three sections of glass formation: in the first section glasses in 273-1273K interval maintain X-ray amorphism; in the second – the tendency of irization film formation at low temperatures is observed; and at further increase of temperature the tendency to surface crystallization becomes evident. Glasses of the third section are distinguished with high tendency to crystallization. The compositions of the first section were chosen as basis ones. On the basis of information sources and investigations of a number of authors the modification of basic boron-free and fluorine-free primers was performed by introduction of titanium oxide, lithium oxide and common salt. As a result boron-free and fluorine-free primer was obtained with quite good adhesion to steel surface and satisfying the requirements to the properties of coatings. The properties of the product obtained at boron-free and fluorine-free primer boiling and as a result of its boiling are considered and the question of primer nature used at modification and boron-free and fluorine-free primers adhesion with steel is considered.

Traditional technology of rolling includes casting of primary billet of large cross-section and then producing thin sheets by hot rolling. Method of direct rolling, in contrast with the traditional technology, allows obtain thin sheets (0.6-6 mm) by combining processes of continuous casting of liquid metal and rolling. The method of direct rolling is fairly simple. Liquid metal is passed through a pair of rotating rolls, which are located in horizontal plane at a certain distance from each other equipped with cooling system. By varying rotation velocity of rolls it is possible to regulate metal solidification front which is necessary to establish required conditions for hot rolling process. In the present paper mechanism of billet formation in the combined crystallizer is considered in detail. Method of theoretical determination of the main technological characteristics of direct rolling for both ferrous and nonferrous metals is conducted. Interrelation of these parameters with construction and energy-power characteristics of the casting-rolling mill is defined. On the basis of the investigation results a pilot casting-rolling mill was designed and fabricated in metal. Fig. 5, Tab. 1, Ref. 6.

Orthoclase gabbro of the Dzirula crystalline massif incorporates the rocks of different genetic groups: protolith of the gabbroic intrusion, hybrid rock – orthoclase gabbro and leucocratic quartz-feldspar bearing formation. The rocks of all three genetic groups are dated by the U-Pb LA-ICPMS zircon age method. The apparent age of zircon in the protolith of gabbroic intrusive and in hybrid orthoclase gabbro, respectively wt.mean 221±1.9 and 221.9±2.2Ma, records the time of crystallization of the intrusive and the apparent age of zircons (wt.mean 323±2.9Ma) from leucocratic quartz-K-feld­spar formations, as well as the inherited Late Variscan age (323±9, 329±8.3, 332±10 and 335±11Ma) of zircons of hybrid orthoclase gabbro corresponds to the age of formation of Late Variscan granitoids widespread in the Dzirula crystalline massif.

The limits of the Kura bay and of the adjoining tectonic high zones and depressions were inherited from the Middle Miocene and continued to exist. They had an important role in controlling the distribution of the sedimentary facies. The poorness in marine faunas of the Early Sarmatian deposits, together with the character of thickness and facies, suggest that these sediments formed in a big brackish basin. Towards the north and south from this basin, great mountain ranges of sublatitudinal direction existed. At the beginning of the Middle Sarmatian there were no important changes in the palaeogeographical and geotectonical situation. The basin expanded slightly towards the north, which is reflected by transgressive deposits of the Middle Sarmatian age on the northern Kakheti range (Chailuri, Manavi, Burdiani). The relatively homogeneous facies allows to suppose that the palaeogeographical and sedimentary conditions did not change for a long time. The orogenic movements, which began at the end of the Middle Sarmatian, reached their maximum in the Late Sarmatian (the Attic orogenic phase) and on the whole territory of Eastern Georgia a continental regime was established. Extension and depth of water bodies were significantly reduced: in the late Sarmatian the sea on the territory of Eastern Georgia was divided into isolated or semi-isolated comparatively small basins – lakes, lagoons.

The process of mechanical drilling of hard rocks is connected with substantial economical expenses connected with high duration of drilling and as the result intense wear of bores. In order to minimize the bores wear the set of mechanical drilling is equipped with plasma torch having a special indirect action design. The said plasma torch provides heating of drilling rocks up to high tempe­­rature and then momentary cooling. This process causes the appearance of thermal impact, which as the result cracks and destructs the processed rocks, which promotes the increase of the resource of mechanical bo­­re operation. Plasma torch construction provides stable ignition of the arc at any depth and operation resource of thermo-loaded units during the whole process of drilling. Fig. 1, Tab. 1, Ref. 3.

Joining of a basic or additional electrode to the engine spark plug is an important technical task. In this article, it is suggested to resolve this problem by resistance surface-to-surface welding. To achieve the uniform tem­pe­rature distribution in the welding zone between the case and the electrode, we must have equal cross-sections of the parts to be welded. For this purpose, we should make two longitudinal cuts 2.5 mm wide in the case, which the additional electrode will be welded to. Based on the heat balance relation of welding, the equation for calculation of the values of welding current strength and density were derived. The numerical values calculated by these equations are in good agreement with those obtained experimentally. Ref. 3.

The heat resultant from fuel burning in operating cylinders does not convert into useful work completely. Significant part of this heat is lost as exhaust gases and cooling water, and because of incomplete fuel burning. The heat carried away by exhaust gases and cooling water can be used usefully. The exhaust gases can transfer heat to any heat carrier (water, vapor, air, etc.) via a cogeneration device. The possibility of designing of the cogeneration device on the base of low-capacity diesel A-41 (37.5 KW) is discussed. It is justified that this device will be capable of producing the average heat duty of 12.6 KW, which is sufficient for heating of the area of 800 m2. Ref. 5.

Agricultural sector is the traditional and essential one for any country’s economy. There are convenient natural-economical conditions for agricultural development in Georgia. In 2006-2009 the decrease of its share in GDP Gross Domestic Product was from 11.2% to 8.3%, and its real produce decreased at 5%. The strategy of economical growth of Georgia should be based on the abilities of the agricultural food-stuff sector in short and long-term periods. According to the comparative preference the country can become competitive in food-stuff producing sphere which may cause the effective usage of national resources, obtain the shares throughout home and international markets and increase the welfare of population.

12.C9.15. Phenolic compounds of wines from Georgian autochthonous grapes, Rkatsiteli and Saperavi, prepared by Georgian (Kakhetian) technology. /A. Shalashvili, D. Ugrekhelidze, T. Mitaishvili, I. Targa­madze, N. Zambakhidze/. Bulletin of Georgian National Academy of Sciences. 2012. – V.6. N3. pp.99-103. eng.; abs.: eng., geo.

The qualitative composition and the quantitative content of phenolic compounds of wines from the Georgian autochthonous grapes, white Rkatsiteli and red Saperavi, prepared by Kakhetian technology are studied. According to the obtained data, in white wine Rkatsiteli the content of catechines is the following: (+)-catechine (32.6 mg/l), (-)-epicatechine (58.6 mg/l), (-)-gallocatechine (43.7 mg/l), and in red wine Saperavi: (+)- catechine (115.4 mg/l), (-)-epicatechine (29.5 mg/l), (-)-gallocatechine (174.4 mg/l), respectively. It is shown that a significant difference in the contents of catechines is observed between white and red wines. Red wine Saperavi contains 3.4 times and 4 times more (+)-catechine and (-)-gallocatechine, and 2 times less (-)-epicatechine than the white wine Rkatsiteli. Out of flavonols kaempferol (13.2 mg/l), quercetin (11.2 mg/l) and rutin (2.6 mg/l) were found in red wine Saperavi, while in white wine Rkatsiteli those compounds are absent. The white wine Rkatsiteli does not contain resveratrol, while in red wine Saperavi its amount is equal to 1.47 mg/l. Out of hydroxybenzoic acids the protocatechuic acid and gallic acid were not found in white wine Rkatsiteli, while in red wine Saperavi their amount is equal to 14.5 mg/l and 21.8 mg/l. Of hydroxycinnamic acids, in red wine Saperavi caffeic acid in the amount of 7.4 mg/l, and o-coumaric acid and syringic acid as traces were found. These acids were not found in the white wine Rkatsiteli. Thus, in qualitative composition and quantitative contents of phenolic compounds the red wine Saperavi considerably surpasses the white wine Rkatsiteli. Tab. 1, Ref. 9.

12.C9.16. The problems of designing titrimetric measurement systems for the analysis of agricultu­ral products and foods. /T. Dzagania, K. Kakheladze, K. Makhashvili, V. Padiurashvili, S.

The nation’s healthcare is one the basic responsibilities of the State. To ensure it, a complex of measures should be taken. Ecological monitoring of agricultural products and foods is an essential part of this complex. There are available various programs for controlling the quality of raw materials and food, and there is wide experience of using engineering facilities for this purpose. For instance, in the 70-ies of the XX century, the GEM/FOOD program was realized in Europe. This program was part of measures aimed at providing food safety. Its objective was collection of information, its transmission and storage for creating the relevant European database. Most of today’s food safety control systems are based on the concept of Hazard Analysis and Critical Control Points (HACCP), which assures food safety control from harvest to consumption. In January 2010 the Law of Food Safety came into force in Georgia. The law stipulates that the foods that are produced in the country, imported into or exported from it should be subjected to continuous quality control. According to the report of the International Finance Corporation of the World Bank, 90% of the companies involved in production, import or export of foods in our country need help (methodical, technical, organizational, etc.) for complying with International Standards. It is obvious that it is impossible to resolve the problems associated with food safety without measuring/controlling the characteristic parameters of foods. For this purpose it is essential not only to have automatic measuring and controlling instruments and devices, but also to rise to a higher level – to create an analytical computer system. It is noteworthy that, when elaborating the concept of automated control systems, the economical efficiency and the ecological safely should be in harmony. Fig. 2, Ref. 7.

The article presents information about the state of agricultural complex on the Kolkheti lowland drained lands. A unilateral specialization in the production of subtropical crops has failed to ensure harmonious development of agricultural. Taking into account the global demand for wheat and the corresponding growth of prices, also in order to provide population with staple food products, it is recommended to change the structure of agricultural lands in the central part of lowland. An increase in lands under wheat and food crops at the expense of perennials requires the use of drainage techniques for one year plants taking into account heavy soils in this part of Kolkheti. The methods to handle the above-mentioned problem are given. Ref. 3.

There has been ascertained the vegetation period of the Alazani River according to individual months, quarters, maximum and minimal water discharge, extremes, alteration and other statistical qualities. By using their dynamics through years the trends and tendencies of the changes have been identified. The figures are of scientific value and can be used in designing and economic organizations for calculating water resources. Due to the warming trend, water evaporation will increase and the river flow will decrease, which will ultimately lead to the lack of water supply in irrigation period in summer. For the aim of mitigation of negative consequences of drought, a set of measures is recommended so as to slow down turning the territory into a desert, increase agricultural produce and improve economic well-being of the population.

A problem of the river flow control can be viewed both from the point of the queuing theory and the theory of storage optimal control. The flow of service (river flow) is a random process. The accumulation and consumption should aim to achieve the desired economical effect. The problem is dynamic; the scheduling horizon (one year) is divided into stages. At the different stages the river flow, consumption and accumulated water are discrete quantities and they are measured in the same units. The flows are independent random variables and, on the bases of rich statistical data, empirical distributions (histograms or tables) can be elaborated for them. Stage-wise volume of water in the reservoir is also random and depends on the flow and the consumption as well. As the flows are independent it represents the Markov chain, which is well determined by means of the matrix of transition probabilities. At each stage the intensity of consumption uniquely defines the transition matrix. By means of the matrix mathematical expectations of income and of losses are determined at each stage. The problem is as follows: to choose the sequence of consumptions (loads) with respect to the stages to maximize the summary profit or to minimize the summary losses. Finally, mathematical model is posed in the frames of Markov decision process and can be easily implemented. Tab. 1, Ref. 6.

Forecasting hydro-chemical regime of Khudoni water reservoir is important for its efficient functioning. Changes in the hydro-chemical regime of the water reservoir depend on many different factors, such as temperature, sources of feeding, physical and geo­gra­phical peculiarities of the basin, its economic use, etc. We used a segment-stratification method to forecast the water quality in Khudoni water reservoir. This model is based on a simple geometric repre­sentation of a sys­tem. The whole volume of the water reservoir is divided into segments, which on their turn are divided into horizontal strata. The water-dissolved oxygen, bio­che­mi­cal consumption of oxygen, nitrate nitrogen, nitrite nitrogen, ammonium nitrogen, phosphate, as well as principal ions and quantitative properties of minera­lization of each stratum are calculated by using the relevant mathematical model. The calculation gained by the above-mentioned method gives a maximally effi­cient picture of forecasting as close to the real picture as possible. Fig. 1, Tab. 7, Ref. 5.

Equations of the analytical function of deformation (con­nection stress-strain) under external impact of cyclic force according to the loading-unloading program of the elastic-plastic environment are obtained. At each cycle of loading-unloading, a loop hysteresis is obtained, the area of which expresses the amount of permanently consumed (dissipation) plastic energy. It is proved that the value of the dissipation energy in repeated cycles is monotonely decreasing, which means the growth of elastic properties of pack environment, and the decline of plastic nature. Presents analytical functions unloa­ding and loading the defor­ma­tion curves, which gives the possibility to determine the area of hysteresis ellipses, which expresses the number of plastic energy at each cycle. Having equations of loa­ding and unloa­ding curves are determined by the values of the coeffi­cients of acquisitions for each full cycle upload-load. For each cycle of the absorption coefficient is the ratio of sales dissipation energy to the sunk cost of total energy consumption. It is proved that depends on the number of cycles: i.e., decreases with increasing – as this pro­cess more and more linearized. The greater the degree of non-linearity up the process, the more is linearization curves of deformation with the increase in cycles of loa­ding and unloading. This is explained by the fact that the more internal friction, the more active the dissipation of the non-linear component of the energy and the growth of the relations of elastic component to the plastic.

In portholes passing under natural geotechnical conditions, theoretical models of definition of seepage indicators are applied in the isotope water-permeable environment that limits their application area. Since the seepage factor is a permanent and active component in formation of the water balance of local agricultural (agro) systems, it serves as a basis for determining the irrigation rate. Based on the seepage features, the questions connected with the movement of water in porous systems of soil represent a function of many interoperating factors. Hence, on the basis of the offered model, the calculation dependences of seepage velocity, seepage factor, water conductivity and porosity for real soils are obtained. Fig. 1, Ref. 5.

In soils, presented by the dispersed-hydraulic porous system, the migrated water gets specific qualities; therefore, definition of characteristics of water seepage in soils becomes complicated. Soils, which represent the multi-component environment, consist of different micro- and macro-particles and the water migrating in these particles gets different qualities. Based on the above, on the basis of the proposed model the range of change and optimum values of the active and passive porosity have been defined. Taking into consideration water seepage, dependences of seepage velocity, initial gradient and irrigation mode are received. Fig. 3, Ref. 4.

After independence of Georgia, as a result of the measures taken in the field of trade liberalization, country has significantly expanded its foreign trade relations and joined the World Trade Organization. Under conditions of foreign trade turnover growth, the country’s import increases more rapidly, exceeding now by 3 times and more the export value. Systematic growth of the negative trade balance is directly linked to the country’s external debt increase. The government should take active and effective measures to increase the production quality, its environmental safety and competitiveness which will create the proper conditions for the successful diversification of Georgian products on the world markets.

Recently the following basic tendencies have been observed in the development of foreign trade of Georgia: Intensive expansion of foreign trade and steady rise of the turnover of goods. In the total turnover the import seems to increase in comparison with the export, due to which the index of negative trade balance is increasing annually. The export of the country is mostly carried out through the expenses of raw and frozen products, as for the import the energy resources, agricultural and its industrial processing products prevail in the market. Replace of it will be easy at the expense of expansion of local industry. To overcome the negative tendencies in country’s foreign trade it is necessary to carry out the incentive activities of export at the expense of forming and pursuing a replacement policy of import.

According to current researches, one of the important factors for improvement of motor cars efficiency during cargo transportation in Georgia is the provision of adaptation of motor vehicles’ traction and speed properties to driving conditions. One of the efficient methods for achieving this task is the selection of motor engine power according to the driving conditions to stipulate high values of average speed of movement and profitability with minimal expenses of fuel and other material supplies. It is established that characteristic integral parameter of assessment of motor vehicles’ traction and speed properties and of their adaptation to operation conditions in real driving conditions in transportation flows is the power-to-weight ratio of motor vehicles. It characterizes the level of motor vehicle supply with energy. Cars with low power-to-weight ratio are moving with low speed at the raising roads on the low steps of transmission under high load conditions (modes), and due to this fact the fuel consumption on the road increases; at the same time transportation flows traffic is hampered and traffic safety is lowered. In case of use of motor cars with high power-to-weight ratio all mentioned parameters improve. Proceeding from abovementioned under given road conditions those value of power-to-weight ratio should be considered as the rational value of motor vehicles’ power-to-weight ratio, which will ensure the complete implementation of motor vehicles’ operational properties and at the same time will provide maximum specific performance of cargo transportation with minimal material expenses. According to mentio­ned above, from the viewpoint of cargo transportation efficiency in Georgia and by taking into account the peculiarities of operating conditions in Georgia the elaboration of methods for determination of rational power-to-weight ratio of freight transport and of creation of corresponding motor vehicles fleet is at present the topical scientific problem.

ABO blood groups antigens have biological and clinical significance. The ABO blood groups antigens has been associated with many diseases, though the explanation between ABO blood groups and disease is still unclear. The aim of this study is to investigate the presence of a possible association between benign tumors of the ute­sus with blood ABO, RhD, Kell and MN groups in women in reproductive periods. In diseased population (60 subject) was investigated for Erythrocyte phenotypic gro­­ups antigens. Immunoserological methods have be­en used to identify the antigens. The obtained results were statistically processed. High frequencies of A (43,3±3,2%), D(91,6±3,5%) and Kell (+) (26.66±5.7%) antigens were found in diseased of benign tumors of uterus comparison with donor. The researches shows, that is increased risk of disease development in carriers of these phenotypes. In summary, according our resear­ch we’ve thought, that blood groups may be a marker for bening tomors of the uterus. Based on these data, these could be used as prognostic factor for bening tomors of the uterus. The study of Erythrocyte group antigens in diseased we may to identify“ high risk” individuals, that help to find ways, which help to control of disease.

Non-convulsive status epilepticus (NCSE) is relatively rare, but recognized condition observed in non-epileptic comatose patients. In coma state NCSE may be precipitated by stroke, severe electrolyte disturbance, acute intoxication, infection, traumatic brain injury and etc. All these critical disorders can cause coma themselves and without clinical EEG investigation it is impossible to attribute impaired consciousness to NCSE, while the condition can be responsive to anticonvulsant medication. The proper and rapid diagnosis of NCSE is challenging, because it can severely impact the patient and often is a treatable and completely reversible state. Case reports describe the state of three comatose patients affected by severe neurological disorders, who were diagnosed as NCSE after EEG investigation. Nor of these patients were noted to have the epileptic seizures and convulsions. The patients were treated with different anticonvulsive medications (Finlepsin, Levetiracetam, Depakin) and fully recovered from coma state. Frequently, physicians could not suspect presence of NCSE in patients with impaired consciousness because of sufficiently complicated underlying illness. Apparently, clinical EEG investigation is useful to be performed in all comatose patients.

Over the past few decades the search for predisposed biological markers has become the course of most priority in scientific psychiatry. Research goal was to reveal the association of alpha-dephenzine concentration in peripheral blood with the disease existence and its progre­ssing in patients with schizophrenia. In-patients diagnosed with schizophrenia have been investigated (av. age – 45.33±1.86), among them 26 males (av. age – 39.41±1.86) and 13 females (av. age – 45.04±2.44). 27 patients with acute form of schizoph­renia (av.age – 44.88±2.42), 12 patients with a chronic form (av. age – 46.33±2.75). 15 healthy volunteers have been investigated as well, 5 males and 10 females among them. The study of alpha-dephe­n­zine concentration by the immunoenzyme method has been implied in the investigation. Research studies reve­aled statistically valid increased concentration of alpha-de­phenzine in patients diagnosed with schizophrenia co­mparing with healthy volunteers. The difference was so evident that qualitative difference would rather be considered than quantitative one. Relying on the results of studies we can estimate alpha-dephenzines as possible biomarkers of schizoph­renia.

The aim of the research is to reveal the cases of Lewis System Antigens Phenotype in West Georgia and setting the connection between antigens expressiveness and IHD. Therefore, we have phenotypically tested 393 people (236 healthy donors; average age 42±7,5 and 157 patients ill with ischemic heart diseases; average age 62,5±7,5). In accordance with the findings, the number of Lewis -antigens among healthy population is 46,6% (110 ±4,8; p<0.05) with Lea-b+ phenotype; 30,9% – with Lea-b- phenotype(73±2,9; p<0.03); 19% – with Lea+b- phenotype-(47±1,7; p<0.03) Only 2,6% cases of phenotype Lea+b+ (6±0,2; p<0.02),were revealed among healthy population. As for the patients with ischemic heart diseases we got the following results: 41% cases of Lea-b- phenotype (65±3,9; p<0.05); 32,8% – Lea-b+ (51±3,2; p<0.03); 21,1% – Lea+b- – phenotype 33±2,9; p<0.03) and 5,6% – Lea+b+ phenotype (8±1,2; p<0.02). On the whole, in the West Georgia the most frequent phenotype is Lea-b+ among healthy population and Lea-b- phenotype among people with ischemic heart diseases. Research was carried out in a control group according to Lewis antigen phenotype. People were separated in two groups; I group -healthy people with Lea-b- phenotype and II group – healthy people with Lea-b+ and Lea+b- phenotypes. On the basis of the research we concluded that people in the first group (with Lea-b- phenotype) had a high BMI, arterial hypertension and lower indexes of high density lipoprotein and triglyceride than the people in the second group(with Lea-b+ and Lea+b- phenotypes. These kinds of changes (characterised to the people with Lea-b- phenotype) are associated with a high risk of ischemic diseases and atherosclerosis. To sum up, people with Lea-b- phenotype have a high risk of ischemic heart disease. In accordance with the findings, Lewis phenotype research can be carried out to detect HID and other diseases as well (hypertension, ischemic insult and insulin-dependent diabetes mellitus).

12.C13.9. Cholinergic stimulation of adrenal medulla is essential for the granulicytopoietic response to lithium. /M. Gedevanishvili, N. Mushkiashvili, N. Gogi­tidze/. Georgian Medical News. – 2012. – N6(207). – pp. 43-46. – ång.; abs.: geo., eng.

Granulocytopoietic response to lithium carbonate (Li+) in rat was eliminated completely by N-cholinergic blocking agent, and independently by alpha-1-adrenergic antagonist. A link between these two contradictory events is explained by release of acetylcholine from the cholinergic preganglionic nerve endings in adrenal medulla triggered by Li+, and subsequent discharge of catecholamines (CA) from medullar chromaffin cells, which on their part activate adrenergic receptors of alpha-1 class on hematopoietic progenitor cells. Respectively, granulocytopoietic response to Li+ is blocked by cholinergic N-blocking agent at the level of adrenal medulla, and by the alpha-adrenergic blocking agent at the level of the hematopoietic cells proper. The stimulatory action of Li+ on granulocytopoietic cells is indirect, while is mediated by CA release from adrenal chromaffine cells. At the initial stages of leukocyte restitution in the acute myelotoxic leucopenia relative increase in “large” lymphocyte fraction (Lge) preceding the increment in granulocyte counts is evident. In this fraction of lymphocytes peripheral blood progenitor cells (PBPC) are expected.

In the presented work antitumor effects of thermo- and phagelysates of Ps. aeruginosa and E. coli on Ehrlich carcinoma growth in mice have been studied. The treatment efficacy was evaluated according to the dynamic changes in volume of cancer tissue, cancer growth inhibition percent and calculations using Semi-empirical mathematical model describing cancer volume variations in relation to time passed after carcinoma inoculation. It was shown that at the early stage of cancer growth all tested bacterial preparations significantly inhibit cancer growth. Antitumor treatment effects were better expressed in animal studies using bacterial pagelysates in comparison to that of thermolysates. Comparative analysis of anticancer treatment efficacy of Ps. aeruginosa and E. coli phagelysates have shown that E. coli phagelysates reveal stronger and more prolonged anticancer treatment properties than phagelysates of Ps. aeruginosa.

At the present stage of infectionist practice in the treatment of acute intestinal infections caused by opportunistic microorganisms, colloidal silver is used with a particle size of 25 nm as an alternative to conventional causal therapy. In 32 rats, distributed in 4 groups of 8 animals each (intact; healthy, got colloidal silver; with a modeled acute intestinal infection in the basic treatment and with the addition of colloidal silver), histological examination was performed of small and large intestine of rats. Oral administration of colloidal silver at a dose of 0.02 mg/day to intact rats did not lead to changes in morphometric parameters compared to the norm, and during early convalescence in rats with acute intestinal infections were observed destructive and compensatory changes in the intestine, which depended on the treatment regimen. With the introduction of colloidal silver decreased activity of the inflammatory process and the severity of morphological changes in tissues of small and large intestine, indicating that the positive effect of study drug compared with baseline therapy.

Correlation between menopause metabolic syndrome and non-alcoholic fatty liver disease (NAFLD) is reviewed. NAFLD refers to a wide spectrum of liver disease ranging from simple fatty liver (steatosis), to nonalcoholic steatohepatitis, to cirrhosis. The causes and pathogenetic factors of the disease are still under investigation. The risk of development of NAFLD during menopause is twice higher in comparison with fertile age and abdominal obesity and insulin resistance is more apparent. This feature is associated with deficit of estrogens during menopause, as risk of development of NAFLD is diminished with substitutive hormonotherapy. The obesity, particularly in the period of menopause, is discussed as additive, independent risk factor of metabolic syndrome and of diseases of hepatobiliare and cardiovascular systems.

In a review article peculiarities of cardiovascular disease among women are considered. The analysis of published data showed that cardiovascular disease (CVD) is common in women. Gender-specific risk factors include oral contraceptives and menopause. Clinical manifestations, major causes of various forms of cardiovascular disease in women are revealed. It was found that women most often than men have coronary micro vascular disease – X Syndrome, which affects the tiny coronary arteries. Coronary micro-vascular dysfunction is prevalent in women with chest pain. There is a greater prevalence of no coronary causes of chest pain in the female population, and chest pain is frequently accompanied by abdominal pain, dyspnea, nausea, fatigue, and greater functional disability. Women tend to suffer from more single vessel and two-vessel disease as opposed to the three-vessel disease seen more often in men. It is concluded that specific research is required to identify risk factors of cardiovascular disease in women in Georgia.

12.C13.17. The role of neuroendocrine mediators in regulatory activity of T-cells. /A. Gokhelashvili, G. Lomsadze, M. Yenukidze, M. Machavariani, N. Goge­ba­shvili, T. Sanikidze/. Georgian Medical News. – 2012. – N7-8(208-209). – pp. 41-46. – rus.; abs.: geo., eng.

The aim of the study was to establish the role of some neuroendocrine mediators (agonists and antagonists of β-adrenergic receptors, progesterone) in regulating T-cells activity. Studies conducted on the culture of leukemiatransformed T-cells (Jurkat cells) (DSMZ-Deutshe Sammulung von Mikroorganismen und Zellkulturen (Germany)). Jurkat Cells (4x105 cells/ml) stimulated with 50 µg/ml fitogemaglutinin A (PHA) at 370Ñ for 5 minutes and then incubated for 24 hours alone, or together with β- adrenergic receptors agonist izopretonolom (at dose of 10-5 M, 10-6 M), an antagonist, propranolol (dose of 10-5 M, 10-6 M) and progesterone (dose 0,07 µl, 0,7 µl) added to the incubation medium. The viability of Jurkat cells was determined by MTT test. It was shown that β-adre­noretseptors agonist, izoprotenol didn’t affect the activity of mitochondrial dehydrogenases in intact and contributed to their low activation (12%) in the mitogen-activated Jurkat cells. β-adre­nergic receptors antagonist, propranolol, promotes a sig­nificant reduction in activity of mitochondrial dehydrogenases, and hence the viability of both intact (40-60%) and mitogenstimulated Jurkat cells (20-40%). Viability of intact Jurkat cells didn’t change, and dose-de­pendently increased in PHA-stimulated Jurkat cells during progesterone exposure. It was concluded that viability of the T-cells and hence their functional activity is lar­gely sensitive to the influence of the β-adrenoceptor antagonists and progesterone. These data should be considered in the clinical application of appropriate drugs.

In view of the reversibility of steatosis and steatohepatitis, their early diagnosis is one of the most significant problems of modern medicine. The aim of the study was the establishment futures of the pathogenesis of NAFLD in postmenopausal women. The study was condu­c­ted on postmenopausal women (n=5), with metabolic syndrome and rate of ALT in the blood at least 4 times greater than its normal maximal value. Patients had to fulfill the following inclusion criteria: at least 12 month of amenorrhea. Verification of the diagnosis of NAFLD was based on abdominal ultrosonografic examination. In addition to collecting history, study of blood lipid profile and ALT, AST, estrogen content in patients enrolled in the study free nitric oxide content in the blood and liver bioptants was determined by Electron Paramagnetic Resonance (EPR) method. The study protocol approved by the Ethics Committee of the Tbilisi State Medical University. Patients by written form confirmed their agreement to participate in the study. In patients with NAFLD levels of total cholesterol, LDL-cholesterol and triglycerides were generally increased in the blood serum, direct correlation revealed between level of NO EPR signal intensity in liver bioptat and triglycerides content in blood (r=0,96; p=0,009). It was concluded that estrogen-dependent factors, such as impaired lipid metabolism and increase expression of iNOS induce accumulation of triglycerides and free fatty acids in the liver, generation excess amounts of NO, which in oxidative stress reveal their cytotoxity and promote progression of NAFLD in postmenopausal women.

Among the factors contributing to the gallstones formation an important role belongs to the inflammation. The goal of our research – determination alterations of the redox balance and cytokines (IL-1α, IL-6, IL-8, TNF-α) content in the blood postmenopausal women with gallstone disease. 58 menopausal women with gallstone disease, who had been admitted to the LTD ”1-st Clinic” (Tbilisi, Georgia) during 2009-2011 were studied. Gallstone disease was proved by ultrasonography method. The control group consisted of 25 menopause aged women without gallstone disease. The Local Ethics Committee approved the protocol, and informed consent was obtained from all participants or their surrogates. Patients was conducted for blood redox status (EPR signals of superoxide (O2-) and lipoperoxide (LOO.) radicals) and citokins (IL-1α, IL-6, IL-8, TNF-α) content. It was revealed increase production of oxygen and lipoperoxide free radicals, macrophage inflammatory cytokines (IL-6, IL-1α, TNF-α) in blood of menopausal women with gallstone disease. It was concluded that macrophages play a dominant role in the inflammatory and oxidative response during gallbladder stones disease in postmenopausal women.

The aim of the study was to establish alteration of nitric oxide (NO) metabolism in placenta and its role in pathogenesis of physiological and complicated with preeclampsia (PE) pregnancy. Fifty women with preeclampsia and 30 control pregnant women were studied. The control group was selected from healthy pregnant women; the pre-eclamptic group consisted of women who were normotensive before pregnancy and during the first 20 weeks of gestation, and developed hypertension associated with new onset proteinuria. NO content in placenta was studied by Electron paramagnetic Resonance (EPR) method. During pregnancy com­pli­cated with PE intensity of EPR signal of adrenodoxin FeS-centres reduced (by 60%), of cytochrome Ð-450 increased by 60% – compared to the same parametres during physiological pregnancy; intensive EPR signal of spin-trapped Lipoperoxide (LOO.) was also detected; in the EPR spectrum of placenta a significant reduction of free nitric oxide content and intensive signals of of nitric oxide complexes with hemic and nonhemic iron were detected. These complexes indicate on the nitrosilation of mitochondrial electron transport proteins with following alterations of their activity and disorders of energo- and steroidogenesis processes in placenta during PE. Alterations of placental nitrosilated complexes during PE suggests that NO plays an important role in the regulation its functions.

The goal of our study was to determine nitric oxide (NO)-dependent mechanisms of skin aging in post- and premenopausal women. 23 women (age 40-50 year) were investigated. Women were divided into 2 groups: I group – reproductive age women (10 patients); II group – menopause age women (13 patients). Patients were included in the menopausal group when they fulfill the following criteria: at least 12 month of amenorrhea. All patients are subjected to a standard diagnostic protocol. In each group we investigated estradiole, lipids and free NO content. Skin of postmenopausal women as a rule was pale, grayish, in some cases revealed pigmentation; skin around the eyes less flexible, wrinkled. Moderate hypercholesterolemia and reduced levels of nitric oxide and estradiole in the blood of studed postmenopausal women (in comparison reproductive aged women) was revealed. Decrease free NO content in blood may be due to the decrease of NO synthesis, as well as the oxidative degradation of NO in the oxidative stress conditions. In article the mechanism of dependence of NO-vasodilatative system activity on the level of hypercholesterolemia and estrogen content in blood are discussed. It was concluded that in menopausal women insufficiency of estrogen’s content is the main factor, which stipulates insufficiency of NO-dependent vasodilatative mechanism, and disorder of subcutaneous vasodilatation in aged (postmenopausal) women which contributes to violations of the oxidative processes in the skin and its rapid aging.

Several factors are contributing to menopausal hypertension; the role of estrogens in pathogenesis of hypertension in menopausal women have not completely established. The aim of the present investigation was to study some aspects of the role of estrogens in the pathogenesis of hypertension during menopause. 93 women with hypertension, who are referred to the Central Clinic of Tbilisi State Medical University (Georgia) during 2009-2011 were investigated. Women were divided into 2 groups: 1 – reproductive age group (43 patients); 2 – menopause age group (50 patients). In each group we investigated estradiole, oxygen (O2-), lipid (LOO.) reactive species, NO and endotheline content and antioxidant enzymes (SOD, catalase, GR) activity. The results of study reveal increased of superoxide – and lipoperoxide – radicals, as well as of endothelin ñontent in blood of menopausal women, while concentration of free nitric oxide decreased; at the same time activity of catalase increased (by 50%), GR reduced significantly (by 38%) and SOD’s activity didn’t change in comparision to reproductive aged group. Negative correlation between the HbNO and estradiole content in blood of reproductive aged women was established (r=-0,60, p=0.03); no dependence between these two parameters in menopausal aged women was revealed (r=-0, 29, p=0,12). It was concluded, that in women of reproductive age probability and risk of hypertension grows in the presence of additional risk factors, such as oxidative stress and/or fluctuations in estrogen’s level towards insufficiency, which leads to reduction of nitric oxide content due to its oxidative transformation in peroxinitrite, or enhanced inclusion in HbNO complexes, whereas development of hypertension in postmenopausal women may develop by different mechanisms, might including inflammation.

12.C13.24. Pheochromocytoma and pregnancy: complications and solutions (case report). /N. Pirtskhalava/. Georgian Medical News. – 2012. – N7-8(208-209). – pp. 76-82. – ång.; abs.: geo., eng.

Hypertension is the most common medical complication of pregnancy. Pheochromocytoma in pregnancy is rare, and if unrecognized, can cause serious perinatal morbidity and mortality. A patient with paroxysmal hypertension, postpartum intraabdominal bleeding, and a recognized pheochromocytoma is described. A 36-yr-old previously practical healthy woman (gravida 4, para 3) presented to our tertiary care centre at at 26 weeks four days gestation with a history of labile blood pressure and severe hypertension. A two week prior to admission she began having episodes of severe headache, sweating, nausea and dizziness. On an obstetric visit she was noted to be severely hypertensive with a blood pressure of 220/120 mmHg. Ultrasound imaging demonstrated a 11,6 cm x 9,2 cm right adrenal mass, biochemical investigations confirmed the diagnosis of pheochromocytoma. The patient was invasively monitored in the intensive care unit and treated with alpha-blockers and doxazosin. A multidisciplinary conference was organized involving endocrinology, anesthesiology, general surgery and obstetrics to determine the most appropriate management of the patient. Childbirth was performed by elective Cesarean Section with simultaneous laparatomic right-sided adrenalectomy. Postoperative period was complicated with intraabdominal bleeding consequently treated during relaparatomy. The primary goals in the management of pheochromocytoma in pregnancy are early diagnosis, usage of alpha-blockers, and avoidance of a hypertensive crises during delivery and definitive surgical treatment. Timing of surgical resection will depend on the gestational age at which diagnosis is made. Cesarean section is the preferred mode of delivery when the tumor is still present. Complications such is bleeding from adrenalectomy site should be considered. This case illustrates that with antenatal diagnosis, advanced methods of tumor localization, adequate preoperative adrenergic blockade and team planning, pheochromocytoma in pregnancy can be treated successfully even in complicated cases.

12.C13.25. Adolescent health care in Italy: a mini-re­view. /V. De Sanctis, G. Filati, B. Fiscina, A. Marsciani, G. Piacentini, G. Timoncini, L. Reggiani, A. Zucchini/. Geo­rgian Medical News. – 2012. – N9(210). – pp. 8-12. – ång.; abs.: geo., eng.

The purpose of this mini-review is to present the National Health System and services available for adolescents in Italy, and to review the most relevant data on morbidity and mortality in Italian teens. Adolescent medicine in Italy is not a separate specialty, but there are some distinct services for adolescents in pediatric departments or gynecologic wards, mostly in large cities where university hospitals or hospital of national relevance are located. Primary health care in Italy is provided mainly by general practitioners (GPs) and pediatricians, and on-call physicians (Guardia Medica) for after-hours medical care and services. The number of centres providing care for adolescents in Italy is 4097 (50% of these are in the North of Italy, 20% in the Central regions and 20% in the South and Islands). The population of Italy on January 1st 2011 was approximately 60,477,881 and the number of adolescents, aged 10 to 19 years, was 6,214,000. The most frequent causes of death in adolescents are motor vehicle accidents – more than half of which are related to drug or alcohol use – followed by cancer and suicide. In primary care, adolescents present with a large number of issues, particularly upper respiratory infections, musculoskeletal problems, pain syndromes, obesity, eating disorders, dermatological issues, mood and somatoform disorders, school and mental health problems, and chronic fatigue, many of which require a coordinated, multidisciplinary management approach. The estimated population with a chronic illness is 8%. There are no specific protocols for the transition to adult medicine physicians for patients with chronic diseases or special health needs. In order to improve the quality and quantity of education in adolescent health for pediatricians and GPs, the Study Group of Emilia and Romagna Region for Adolescent Health Care (SGA-ER) is going to organize, beginning in 2012, a two year educational intervention course in adolescent health.

Sexuality and sexual function are important to persons with disabilities just as they are to their able-bodied counterparts, but knowledge about sexual and reproductive health (SRH) among persons with disabilities is frequently inadequate. Adolescents and young adults with physical disabilities are less active socially, and have difficulties in developing intimate relationships. Thus, despite greater needs for SRH education and service delivery than persons without disabilities, dedicated services regarding sexuality and physical disabilities are scantly reported. Together with a literature survey on sexuality and disability in adolescents, a unique comprehensive SRH service for young people with physical disabilities is described in this review. Despite being interdisciplinary, the utilization of the service was limited due to difficulties in transportation to the clinic and in finding escort for aid in accessibility to public transportation. Health authorities should provide the resources for the development of accessible comprehensive multidisciplinary SRH services dedicated to young people with disabilities, and thus fulfill the United Nations General Assembly declaration on the rights of persons with disabilities.

12.C13.27. Effects of growth hormone on heart structure and function in adolescence. /M. Toumba, V. Neocleous, C. Shammas, A. Jossif, N. Skordis/. Georgian Medical News. – 2012. – N9(210). – pp. 33-39. – ång.; abs.: geo., eng.

Until recently, growth hormone (GH) and insulin-like growth factor 1 (IGF-1) were considered to control only linear growth. Apart from growth effect, GH has additional important physiological functions in the human body influencing several metabolic processes, body composition, muscle strength, and bone mineral density. In adolescence, where the majority of these physiological functions reach a zenith, GH plays a crucial role. The ability of GH to trigger cardiac muscle growth by direct and indirect effects plays a pivotal role in the physiology of the heart. Patients with childhood or adulthood onset of GH deficiency are exposed to increased risk for cardiovascular morbidity. GH treatment may have beneficial effect on the cardiovascular system in GH deficient adolescents. On the other hand discontinuation of GH treatment in these patients may result in the accumulation of relevant cardiovascular risk factors such as increase in body and abdominal fat and LDL and total cholesterol concentrations. No potential adverse cardiac effects of GH therapy have been so far demonstrated in short stature patients with normal GH secretion. Nevertheless, no evidence of heart hypertrophy or cardiomypathy has been documented in adolescents with GH excess has been reported in adults. Nonetheless, normalization of GH and IGF-1 levels in such patients is essential in order to arrest cardiovascular disease later in life.

12.C13.28. Genetic defects in the CYP21A2 gene in heterozygous girls with premature adrenarche and adolescent females with hyperandrogenemia. /V. Neocleous, C. Shammas, AP. Phedonos, E. Karaoli, A. Kyriakou, M. Toumba, LA. Phylactou, N. Skordis/. Geor­gian Medical News. – 2012. – N9(210). – pp. 40-47. – ång.; abs.: geo., eng.

Congenital adrenal hyperplasia (CAH) is a common autosomal recessive disorder primarily caused by mutants in the CYP21A2 gene. Heterozygosity for CYP21A2 mutations in females increases their risk of clinically manifesting hyperandrogenism and the present study was designed to seek evidence on the prevalence and consequences of heterozygous CYP21A2 mutations in children with premature adrenarche and adolescents with hyperandrogenemia. The hormonal response to ACTH was evaluated in 17 girls with clinical signs of premature adrenarche and 17 adolescent females with hyperandrogenemia, along with direct DNA sequencing and MLPA analysis for mutations in the CYP21A2 gene. The suspicion of heterozygote state was based on the median plasma 17-OHP before and 60 minutes after ACTH stimulation. All 34 patients were identified as carriers of CYP21A2 mutations. The most frequent mutations among this cohort of carriers were the mild p.V281L (52.9%), followed by p.Q318stop (20.6%), p.V304M (8.9%), p.P482S (5.9%), p.P453S (5.9%), large deletion/conversion exons 1-4 (2.9%) and large deletion/conversion exons 6-8 (2.9%). Higher values of stimulated 17-OHP levels were found in the carriers of the p.V281L mutation compared with carriers of other mutations (mean=21.9 nmol/L vs 17.0 nmol/L). This finding supports the already identified notion that carriers of the mild p.V281L are at higher risk for hyperandrogenism than carriers of severe mutations. In conclusion: a. Females with premature adrenarche and hyperandrogenemia are likely to bear heterozygous CYP21A2 mutations, therefore systematic evaluation of 17-OHP values in combination with the molecular testing of CYP21A2 gene is beneficial, b. carriers of the mild p.V281L, are at higher risk of androgen excess compared to carriers of other types of mutations.

12.C13.29. Continuous glucose monitoring, oral glu­cose tolerance, and insulin – glucose parame­ters in adolescents with simple obesity. /A. El Awwa, A. Soliman, M. Al-Ali, M. Yassin, V. De Sanctis/. Georgian Medical News. – 2012. – N9(210). – pp. 47-53. – ång.; abs.: geo., eng.

In obese adolescents pancreatic beta-cells may not be able to cope with insulin resistance leading to hyperglycemia and type2 diabetes (T2DM). To assess oral glucose tolerance, 72-h continuous blood glucose concentrations (CGM) and calculate homeostatic model assessment (HOMA), and the quantitative insulin sensitivity check index (QUICKI) in 13 adolescents with simple obesity (BMI SDS=4±1.06). OGTT performed in 13 obese adolescents (13.47±3 years) revealed 3 cases (23%) with impaired fasting glucose (IFG: fasting glucose >5.6 mmol/L), 4 cases (30%) with impaired glucose tolerance (IGT: 2h blood glucose >7.8 <11.1 mmol/L), and none with diabetes. Using the continuous glucose monitoring system ( CGMS), IFG was detected in 4 cases, the maximum serum blood glucose (BG : 2h or more after meal) was >7.8 and <11.1 mmol/L (IGT) in 9 children (69%) and >11.1 mmol/L (diabetes) in one case (7.6%). Five cases had a minimum BG recorded of <2.7 mmol/L (hypoglycemia). No glycemic abnormality was detected using HbA1C (5.7±0.3%). 11/13 patients had HOMA values >2.6 and QUICKI values <0.35 denoting insulin resistance. Beta cell mass percent (B %)=200±94.8% and insulin sensitivity values (IS)= 50.4±45.5% denoted insulin resistance with hyper-insulinaemia and preserved beta cell mass. In obese adolescents, CGMS is superior to OGTT and HbA1C in detecting glycemic abnormalities, which appears to be secondary to insulin resistance.

Aim of the research: Evaluate ECG parameters and detect changes in capillaroscopy parameters in children and adolescents with Diabetes mellitus type 1 (DMT1). ECG and capillaroscopy were performed in 32 children and adolescents (6-15 years old, 17 boys,15 girls) with DMT1. Disease duration – less than 2 years -13, 2-4 years – 10, 5-10 years – 9 cases. The patients were divided into two groups: I group – 12 patients with no complications of DMT1 (in all them duration of disease was less than 2 years), II group – 20 patients with diagnosed cardiac complications of DMT1 (diabetic cardiomyopathy, angiopathy). Additionally 6 of them had diabetic encephalopathy, 4 – diabetic encephalopathy and peripheral neuropathy, 4 – nephropathy and retinal antipathy. Level of glycosides hemoglobin was 8-11%, level of glucose 4 to 15 mmole/L. Control group included 20 healthy children of the same age. In group I ECG is less informative. Hypertrophies of left ventricle and atrium and disorders of repolarization were mainly found in group II. In 62.5% of cases rhythm and conduction disorders were revealed, which were more often in group II. Capillaroscopy changes (pale and cyanotic background, decreasing of the number of capillaries in sight, dilated and contracted diameter, pathological shape and order of capillaries, slow blood flow) were seen both in I and II groups with more prevalence and intensity in the latter one. In children and adolescents with Diabetes mellitus type 1 ECG and capillaroscopy should be performed on the regular basis in order to reveal early changes and start the appropriate treatment in time.

12.C13.31. Clinical, biochemical and radiological manifestations of severe vitamin d deficiency in adolescents versus children: response to therapy. /A. Soliman, V. De Sanctis, A. Adel, A. El Awwa, S. Bedair/. Georgian Medical News. – 2012. – N9(210). – pp. 58-64. – ång.; abs.: geo., eng.

Objectives: to compare clinical, biochemical and radiological manifestations of severe vitamin D deficiency (VDD – serum 25 OH – vitamin D level <10 ng/ml) in adolescents and children and to investigate the effects of an intramuscular injection (IM) of vitamin D3 megadose. Design: in this prospective study 36 adolescents and 45 children with severe VDD were studied. An IM dose (10,000 IU/kg, max 600,000 IU) of cholecalciferol was injected and parameters of calcium homeostasis were measured at intervals of 3 months. Results: at presentation, infants and young children (age 1.9±0.5 years) with severe VDD had enlarged wrist joints (42/45), cranial bossing (39/45), wide anterior fontanel (27/45), Harrison’s sulcus (11/45), chest rosaries (27/45), bow legs (29/45), delayed teething (40/45), delayed motor milestones (36/45), short stature (length/height SDS <-2)(12/45), craniotabes (4/45) and hypocalcemic tetany (11/45). The most frequent biochemical abnormality was high alkaline phosphatase (ALP) (45/45), followed by low phosphate (PO4) (36/45) and low calcium (Ca) (8/45). Adolescents with severe VDD presented with pain in weight bearing joints, back, thighs, knees, and calves (30/36) difficulty walking and/or climbing stairs and/or running (8/36), muscle cramps and/or facial twitches and/or carpopedal spasms (2/36) and genu valgum (2/36). Biochemical serum abnormalities included high ALP (31/36), low phosphate (10/36) and low Ca (4/36). Variable radiological manifestations due to VDD were detected in all children (45/45) and in some of adolescents (19/35). Two different radiological patterns have been recognized in adolescents. Three months after injecting a mega dose of cholecalciferol all biochemical abnormalities were corrected with significant improvement of symptoms related to VDD had been reported in all children (45/45) and in the majority (33/36) of adolescents with VDD. 3-6 months after the injection, complete healing of the radiological evidence of VDD was achieved in all rachitic children and the majority of adolescents (16/19). Conclusion: it appears that adolescents adapt better to severe VDD compared to infants, with less severe clinical, biochemical and radiological manifestations. An IM mega dose of cholecalciferol is effective therapy for treatment of VDD in children and adolescents for 3 months but not for 6 months.

12.C13.32. Papillary thyroid microcarcinoma in thalassaemia: an emerging concern for physicians. /V. De Sanctis, S. Campisi, B. Fiscina, A. Soliman/. Georgian Medical News. – 2012. – N9(210). – pp. 71-76. – ång.; abs.: geo., eng.

The occurrence of malignancies in thalassaemic patients is an emerging concern for physicians. In the last five years, in a single Thalassaemia Unit following 195 thalassaemic patients, eleven cases of carcinoma were diagnosed: 4 cases of liver, 1 of lung, 1 of adrenal gland and 5 cases of papillary thyroid carcinoma (patient mean age 42.6 years).Therefore, we decided to perform a thyroid ultrasonography (US) in addition to the periodic (6-12 months) assessment of FT4 and TSH in all adult patients with thalassaemia followed at the Thalassaemia Unit of Siracusa and at the Outpatient Clinic of Quisisana Hospital of Ferrara. Thyroid nodules were found in 8.6% of 58 examined thalassaemia major or intermedia patients. To exclude thyroid malignancy, fine needle biopsy (FNAC) under US guidance was performed. A diagnosis of incidental papillary thyroid microcarcinoma (PTMC) was made in 3 female patients with iron overload. According to the World Health Organization, PTMC is defined as papillary thyroid carcinoma measuring < or = 10 mm in the greatest dimension. Two patients were HCV positive. All underwent a total or subtotal thyroidectomy with histological confirmation of the FNAC cytology diagnosis. In conclusion, it seems that patients with thalassaemia have a substantial risk for malignancies. Further studies are needed in these patients to clarify the possible link between cellular iron content, hepatitis C virus infection and cancer development. A thyroid ultrasonography is recommended for all adult thalassaemic patients in addition to the annual FT4 and TSH assessment.

12.C13.33. Some effects of mustard oil and cinnamaldehyde on spinal neuronal responses to cutaneous stimuli in male rats. /M. Tsagareli, A. Merrill, N. Tsiklauri, M. I. Carstens, I. Nozadze, G. Ghurtskaia, E. Abzianidze, E. Carstens/. Bulletin of Georgian National Academy of Sciences. 2012. – V.6. N3. pp.104-116. eng.; abs.: eng., geo.

Transient receptor potential (TRP) channels are being ardently pursued as targets for pain therapies. They play an important role in transducing thermal, mechanical and chemical stimuli for somatic sensation. Several TRP channels exhibit sensitivity to increases or decreases in temperature as well as chemical ligands that elicit similar thermal or painful sensations; these include mustard oil, cinnamaldehyde from cinnamon, menthol from mint, gingerol, camphor, capsaicin from chili peppers, eugenol from cloves, and others. Mustard oil [allyl isothiocyanate (AITC)] and cinnamaldehyde (CA), agonists of the ion channel TRPA1 expressed in sensory neurons, elicit a burning sensation and heat hyperalgesia. In this work, we tested whether these phenomena are reflected in the responses of lumbar spinal wide-dynamic range (WDR) neurons recorded in anesthetized male rats. Responses to electrical and graded mechanical and noxious thermal stimulation were tested before and after cutaneous application of AITC or CA. Repetitive application of AITC initially increased the firing rate of 52% of units followed by rapid desensitization that persisted when AITC was reapplied 30 min later. Responses to noxious thermal, but not mechanical, stimuli were significantly enhanced irrespective of whether the neuron was directly activated by AITC. These findings indicate that AITC produced central inhibition and peripheral sensitization of heat nociceptors. CA did not directly excite WDR neurons, and significantly enhanced responses to noxious heat while not affecting responses to skin cooling or mechanical stimulation, indicating a peripheral sensitization of heat nociceptors. Overall, the presented data with our behavioral results support the idea that thermo-sensitive TRPA1 channel represents a promising target for the development of analgesic drugs in relief of pain.

12.C13.34. The maximum heart rate as a parameter of sport-age functioning. /G. Zubitashvili/. Bulletin of Georgian National Academy of Sciences. 2012. – V.6. N3. pp.117-120. eng.; abs.: eng., geo.

The maximum heart rate is the variable that is very important in determining the training quality as well as to avoiding unnecessary loading on the body. In spite of the known fact that heart rate depends on age, gender, sportive qualification, type of sport, load intensity and other environmental factors – it is still unknown exactly how much its value is affected by the factor of training. Aforementioned determined the research aim: to study the maximum heart rate value dependence on the age and training level on an example of different ages of judokas(8-20 year). The maximum heart rate was measured by palpation during one minute. In order to achieve a maximum heart rate value in judokas developed fast durability test (fast throws) was used by the author, lasting for 100 seconds. Quantitative heart rate data received after completing the test were depicted as minimum, average and maximum values (p<0.05). The study compared the data of untrained persons and judokas (20-22 years of age). It was found that on the one hand training factor somewhat increases this index and the difference makes 7.1 beats per minute. On the other hand, it is proved that the maximum heart rate is affected by the age factor, and therefore this index from 8 to 20-years of age decreases annually on average by1.2 beats (from 212 to 196). The obtained results show that on the example of the heart rate the functional development for judokas extends well beyond the general biological characteristic regulations and makes standards specific for it.

12.C13.35. Helicobacter pylori urease activity and spread of Candida spp in patients with gastric cancer. /Sh. Khetsuriani, Z. Khetsuriani, T. Muralidhasan, K. Chandran/. Bulletin of Georgian National Academy of Sciences. 2012. – V.6. N3. pp.121-124. eng.; abs.: eng., geo.

Nowadays, more than 50% of the world population are infected with Helicobacter pylori. It is a well-known fact that this microorganism is of a great danger for people in 20-30% cases. It is also known that the index of infection, caused by H. pylori, depends on geographic areas, ethnics and race, factors of habits, sex, age and social environment. It is especially common in economically under-privileged countries. This infection is mainly spread in the kind of gastroduodenal diseases: chronic gastritis, peptic ulcer disease, MALT-lymphoma, gastric cancer. According to certain literature the mentioned bacterium causes diseases of other visceral organs of humans. The aim of our research was to study H. pylori urease activity, spread and coexistence of Candida spp and H. pylori in patients with gastric cancer. 24 patients with gastric cancer (GC) were involved in the study (National Cancer Center, Tbilisi). Identification of strains H. pylori, Candida spp and other gram-negative rods and gram-positive cocci were performed by established methods, on the basis of morphological, tinctorial, cultural and biochemical properties. Ages of patients ranged from 50-73 years with a male:female ratio of 1:3. Gc was more frequent in antrum (58.33±10.07%). Microorganisms were isolated both in monocultures and in associations. There were 19 H. pylori+ patients (35.84±9.78%). Candida spp were isolated in 30.18±9.35% cases. Other organisms were in a small amount (gramnegative rods, gram-positive cocci.). Correlation of H. pylori and Candida spp was higher in comparison with other species. The highest urease activity of H. pylori was revealed within 24h (42.10±10.07%). Fig. 1, Tab. 2, Ref. 11.

12.C13.36. Action of certain pyrrole derivatives on brain cortex during hemorrhagic shock in cats. /Gr. Sulaberidze, M. Ghvaladze, E. Chkonia, T. Gegeshidze, T. Buachidze, M. Chkhaidze/. Bulletin of Georgian National Academy of Sciences. 2012. – V.6. N3. pp.125-130. eng.; abs.: eng., geo.

During hemorrhagic shock (HS), in which the destructive process develops, the brain cortex sharply reacts to hypoxia. The pyrrole derivative PV-88 is characterized by Ca2+ slow L channel blocking effect. Subsequently, it protects the brain cortex cells from overloading by Ca2+ ions. Possibly, it also affects T channels due to the cerebral-protective effect of this class of preparations. The experiments were carried out on male cats. In total three series of experiments were conducted with 5 animals in each: one series in conditions of HS, the second series at the 80th minute of HS against the background of verapamil action, and the third series as a result of PV-88 effect. Modeling of the hemorrhagic shock development was maintained up to 40 mm Hg the mean arterial pressure (MAP), gradually decreasing during 1 hour (HS60). The blood exfusion at 40 ml/kg was done against the background of artificial ventilation, which made 130-150 ml/min. The arterial blood pH was maintained at 7.35-7.45, and PO2 – 90 mm Hg and more. The cat’s body temperature stability varied between 37.8°C and 38.2°C. In the right femoral artery MAP was measured invasively, and from the left one the blood exfusion was done. Verapamil at the dose of 0.25 mg/kg and PV-88 at the dose of 3.0 mg/kg dissolved in normal saline, the volume of which did not exceed 1/20 of the exfused blood, were administered into the cat’s right femoral vein. The animal’s death was caused by putting it asleep at the 80th minute from the start of blood exfusion. We took the left frontal lobe (Lobus frontalis) of the brain cortex for examination by the electron microscope. Our research shows that PV-88, which is an acidic nitrate, 1-3(diethylamide propyl-3(n-fluorophenyl-3-oxopropen)pyrrol, is characterized by a more marked protecting ability to astrocytes and neurocytes, than preparation verapamil.

In this work different data sets of the blood pressure and heart rate characteristics of persons from different blood pressure categories have been investigated. In particular, the systolic, diastolic and heart rate time series obtained from 24h ambulatory monitoring were recorded. These data have been collected from 160 persons (91 men and 69 women) residents of Tbilisi. The age of patients for the present investigation was in the range of 30–70 years. Blood pressure and heart rate variability data in these patients have been recorded in the standard calm sitting conditions. Together with these, recorded during the investigation data sets, additionally we have carried out analysis of calculated data sets. Namely time series, such as the pulse pressure and the mean arterial pressure data sets have been analyzed. Patients have been grouped into four different blood pressure categories according to the guidelines of the European Society of Hypertension and the European Society of Cardiology. Statistical features of these data sets, both measured and calculated, for patients from different blood pressure categories were calculated and compared. Standard statistical test was used and coefficients of variation of heart rate and blood pressure time series were calculated. It was shown that there is clear correlation between statistical properties of the analyzed characteristics and level of blood pressure in different categories. Normal and high normal blood pressure categories of patients from different blood pressure categories reveal a clear difference in terms of the statistical features of blood pressure and heart rate characteristics.

12.C13.38. Brain structural-hemodynamic changes in patients with potential cardiac source of embolism. /F. Todua, D. Gachechiladze/. Bulletin of Georgian National Academy of Sciences. 2012 . V.6, N2. pp. 145-152. eng.; abs.: eng., geo.

The aim of our study was to evaluate the brain structural and haemodinamic changes in patients with potential source of cardiogenic embolism. In the period of 2002-2007 116 patients with carotid system severe and chronic dyscirculation were investigated. Patients age varied between 42-76 years. The patients were divided into 2 groups. Group I – 56 patients (mean age 62±7.3 yr) with potential source of cardiogenic embolism (PCSE) (atrial fibrillation, endocarditis, aortic or mitral valve calcinosis, postinfarct aneurism). Source of embolism was defined by corresponding diagnostic tools: ECG, 24 h, Holter monitoring, echocardiography. Patients with extra-intracranial artery haemodynamically or embologenous pathology were excluded from group I. Group II: 60 patients (mean age 61±8.4 yr) with lack of PCSE and with evidence of carotid artery atherosclerotic disease (CAD). All patients underwent routine neurologic examination, functional status study by Rankin scale, brain computed (CT) or magnetic resonance tomography (MRI), extra-intracranial artery Color Doppler, MDCT or MR-angiography. Examination revealed prevalence of symptomatic cerebral ischemia in group I. In comparison, in group II cases of chronic cerebral dyscirculation was noted. By CT and MRT images of infarction were divided into 5 subtypes: total, cortical/subcortical, deep, small cortical, lacunar infarctions. In the PCSE group in 39 (69%) cases the presence of infarctions was noted. From them in 24 cases total or cortical/subcortical infarctions were present. In the CAD group non-focal changes (diffuse, atrophy changes) prevailed 31 (52%). In the CAD group in 49 (82%) cases atherostenotic stenosis of the internal carotid artery (ICA) was revealed. Patients had a higher frequency of moderate stenosis of the symptomatic internal carotid artery (ICA) side 28 (58%) and lower frequency of severe stenosis 5 (8%) and occlusion 3 (5%). Potential embologenous atherosclerotic plaques were defined in 28 (47%) cases. By TCd-embolodetecting cerebral emboli was defined in 13 (72%) of 18 PCSE patients and 11 (65%) of 17 CAD patients. Transcranial Doppler examination revealed flow decrease in middle cerebral (MCA), and anterior cerebral arteries (ACA) in PCSE patients. In cases of large infarction flow velocity at the MCA was 32.6± 4.8cm/s. In comparison, in the CAD group flow parameters in the anterior circulation arteries were at normal levels. Only in the cases of ICA severe stenosis or occlusion flow decrease in the ipsilateral MCA and ACA was noted. Our data show that PCSE has a tendency to have a larger infarction, combined superficial and deep territorial, bilateral involvement, high recurrence rate. Cardioembolic stroke is associated with a worse outcome than other stroke subtypes. In patients with carotid artery atherosclerotic changes the main reason of brain infarction may be atherothromboembolism from nonstable carotid atherosclerotic plaque. The diagnosis of cardiogenic or large artery stroke relies on detection of potential emboligenic sources in the absence of other etiology of equal or greater plausibility. Early application of modern neuroimaging techniques raises the diagnostic accuracy in the evaluation of patients at risk for cerebrovascular cardisease. In patients with a potential source of cardiogenic embolism careful complex examination of the cardiac status and extra-intracranial blood flow conditions is quite important.

Using different methods of statistical data analysis we investigated blood pressure and heart rate variability characteristics of 160 persons in the age range from 30 to 70 years. By their systolic blood pressure values, participants of this research were grouped in optimal, normal, high normal and first grade hypertension blood pressure categories according to guidelines for Management of Hypertension. Data sets of measured as well as calculated characteristics such as systolic and diastolic pressures, pulse pressure, the mean arterial pressure and heart rate of participants were analyzed. By this analysis we aimed to investigate relation between the level of blood pressure and statistical and distributional features of mentioned characteristics in different classification categories. The most important task was to compare variability features of arterial pressure and heart rate characteristics in persons falling into normal and high normal hypertension categories. This was caused by the fact that grouping of patients in these close groups do not ensure that variability features of their blood pressure and heart rate characteristics will necessarily differ. Results of our analysis convince, that there is clear reference between variability features of analyzed characteristics (systolic, diastolic, pulse pressure, the mean arterial pressure and heart rate) and the level of blood pressure in different categories. Moreover, despite of closeness of threshold values of the blood pressure, established by guidelines for normal and high normal categories of a hypertension, the analyzed features of patients from these categories were found significantly different by their statistical and distributional features.

12.C13.41. Application of electrohydraulic method for high dispersive synthesis of magnetic nanofluid for medical purposes. /V. Mikelashvili, J. Markhulia, Sh. Kekutia, R. Tatarashvili/. Basic paradigms in science and technology development for the 21st Century. Trans., Int. Sci. Conference. Tbilisi. 19-21 Jun. – 2012. – v.I. – pp. 350-355. – geo.; abs.: geo., eng.

Several problems must be solved for the synthesis of magnetic nanofluid of medical application which represents colloidal disspersion with particle volume concentration of 25%. First of all it is necessary to gain magnetic particles with size less than 8-15 nanometers and to cover the particles of dispersive phase by the stabilizing molecules, which must prevent the agglomeration of particles and at the same time provide formation of steady colloid system of one-domain magnetic particles. Although today existing dispersive methods such as ultrasonication or centrifugation partially ensure averege quality of deisspersity, the problem to decrease formation size (20-80 nm) is still actual. The electrohydraulic method for better dispersity, stabilization and homogenous size distribution of Fe3O4 nanofluid, synthesized by chemical method, is proposed in contrast to centrifugation and ultrasonication methods. The essence of this method consists in discharging by special pulse electrical current into covered or open vessel constituting magnetic fluid into two discharging rods resulting high hydraulic pressure around discharging zone accomplished by mechanical breaking. Resonant processes and strong infra and ultra oscillations additionally dispergate and dismiss large materials, breaks through the sorption and chemical conjugates in the fluid. Fig. 3, Ref. 15.

Homeopathic (H) medicine is nanopharmacology. How do homeopathic nanoparticles act on the human organism? For this pharmacological effects of H and allopathic belladonna (BL) and barberry (BR) are considered in this work. These effects are manifested by double phase action of remedies. At present it’s generally acknowledged pharmacological principle and is known with title “The law of Arndt-Shulz”. The alkaloid of BL – Atropin provokes the blockade of parasymphathic nerves with therapeutic dose, but H BL, by contrast, has M-cholinomymetic action. That’s why middle dilutions of H BL (C12-C30) cures such symptoms, which manifest as side effects, while using middle doses of its alkaloid – Atropin. The minimal micro doses or high potentials of H BL are effective for cure of those spheres, which are damaged by Atropin’s maximally high doses. Analogously, the higher is HBR delusion, the wider it manifests it’s double phase action. Double effect exists also between substances toxic and microdoses. For example, Arsen, Mercurius dulcis and other remedies are used in homeophathy for cure, which are poisons in ordinary doses. Thus, double phase action of remedies explains densel connection between allopathic remedies and homeopathic nanoparticles, which proves, that homeopathy and allopathy are two interadditional medicines. Homeopathy may be defined as one of the therapeutic directions, which acts on nanoparticle levels. Ref. 8.

The success indicator in competition is the specific index of an organization which ensures its privileged position over competitors on the market. It is not difficult to guess success indicator in industry. It is comparatively difficult to establish the sources on which their privileges are based. There are many sources to achieve competitive preference in industry. Though, the most important is personnel motivation, as other sources of achievement of preference lose significance if personnel are not properly motivated. Modern management discusses motivation as a manager’s ability to manage team in such a manner that each of them do what is necessary and when it is necessary. Motivation is conditioned by many rather than individual factors. Ref. 6.

Communication (from Latin "communis", meaning to share) is the exchange of thoughts, messages, or information, as by speech, visuals, signals, writing, or behavior. Communication requires that the communicating parties share an area of communicative commonality. The communication process is complete once the receiver has understood the message of the sender. Communication is the key factor in the success of any organization. When it comes to effective communication, there are certain barriers that every organization faces. People often feel that communication is as easy and simple as it sounds. No doubt, but what makes it complex, difficult and frustrating are the barriers that come in its way. Sometimes communicating bad news is as "simple" as having to admit that you made a mistake. Being accountable, direct, and prepared with a plan to move forward, all apply to admitting mistakes. It is also important to add on a "lessons learned" to your thought process and your discussion. How did the mistake happen, what are you doing to ensure it does not happen again? Holding on to information because you are afraid to come forward is not the answer. You will earn respect by owning your error and asking for help when you need it. If you are an effective communicator all the time, people will feel you have respect for them by your constant connection. This respect will make them more willing to listen to what you have to say and understand why you have to say it. Effective communication can be achieved only when the words used are brought to a common level of understanding for both parties. Ref. 11.

Basic Paradigms in Science and Technology Development for the 21st Century. Trans., Int. Sci. Conference. Tbilisi. 19-21 Jun. – 2012. – v.I. – pp. 3-11. – geo.; abs.: geo., eng.

The work gives the assessment of the possible cumulative impact of the three water reservoirs located in the River Enguri gorge on the environmental micro-climate. The spatial scales and intensity of the impact of Jvari, Khudon and Nenskra water reservoirs on the air temperature and humidity are identified by using the analytical solution of a two-dimensional stationary mathematical model of turbulent heat exchange and moisture circulation on the background of the horizontal wind given in the surface atmosphere. Assessment of the cumulative effect of the water reservoirs on the environment is made by super-positioning of the analytical solutions gained for each of the water reservoirs, i.e. the values of the impact effects of the three water reservoirs are summed up at every point of space. The possible cumulative impact of the series of water reservoirs on the regimes of wind and atmospheric precipitations is also assessed. The gained results suggest that any significant change in tempe­rature or humidity may occur only in up to 5 km from the water reservoir coastline, in the wind direction. The impact of the series of the water reservoirs on the atmospheric precipitations and wind values is insignifi­cant. Thus, no significant changes in the climate of the region are expected as a result of the cumulative impact of the series of the water reservoirs. Tab. 3, Fig. 3, Ref. 9.

Tbilisi. 19-21 Jun. – 2012. – v.I. – pp. 12-16. – geo.; abs.: geo., eng.

The seismic and hydro meteorological risks of the possible damage to the designed Nenskra hydroelectric power plant dam are considered. The dam stability criterion is obtained, and its analysis is used to show the insignificant role of hydro meteorological processes (strong rain, flashflood, flood) as compared to the seis­mic risk. The fault line running in the given region may have impact on the dam stability. It is characteri­zed by earthquakes with the magnitude of M=5; 2,5and 10% probability for a 50-year-long period. By admitting the total disintegration of the dam, the peak discharges of the originated flashflood wave are calculated on the fault site and along the river transit areas. For instance, the wave discharge at KHUDONHESI (Khudon hydro­elec­tric power plant) dam may reach the value of 7x104m3/sec. The time taken by the flashflood to cover the distance from the Nenskra dam to Khudon dam is approximately 1 hr. The work states that such a scenario of events may have an extremely negative impact on the beds of the Nenskra and Enguri rivers and settled areas near them, and Khudon hydroelectric power plant dam and water reser­voir will be under the hazard of damage.

The natural resources of Georgia and other Caucasian countries are their main natural wealth. At the same time industrial and domestic wastes are a heavy burden for the nature of these counties that utterly aggravates the environmental situation and threatens several regions of Georgia and other Caucasian countries. Today the problem of disposal and utilization of industrial and domestic wastes is very urgent, and demands enormous expenses from the budget of the countries. Thus it is necessary to develop and apply industrial methods of utilization of wastes, which need low investments, have high profitability, are environmental safe and will contribute seriously to the economical progress of the regions and of the countries as a whole. Achieving sustainable deve­lopment is one of the most important problems of modern Society. Sustainable Development must balance the needs of society, the economy, and the enviroment(the so called “triangle” of SD). Therefore, it is important to be able to influence all kinds of the factors that determine the level of sustainable development. Environmental and economic impacts of the implementation of microwave pretreatment in industrial utilization of hazardous waste by means of microwave enhanced halogen-ammonium roasting/ leaching of manganese-bearing waste and processing of inert polymeric wastes using utilization with circulating catalysts in Georgia and other South-Caucasian countries were estimated. Our study showed the possible advan­tages of the developed methods involved : low costs of environmentally friendly methods; high economic effici­ency; high effectivity of decontamination and remediation.

Sustainable development is a response to the global environmental crisis, fearful development of industry and huge population growth – all of this ultimately leads to the depletion of natural resources and cause irreparable damage to a valuable ecosystem. Sustaina­bility is applicable in many areas of design, including an interior design. Sustainable interior design creates ecologically sustainable and healthy inner space. While minimizing negative impact on the environment green designers create a physiologically and psycho­logi­cally healthy living space. There are some basic factors which must be taken into account: the presence in the interior of fresh air, environmentally friendly materials and daylight. Sustainable interior design harmonizes relations between human and nature and is a nece­ssa­ry factor in maintaining environmental sustainability. Fig. 2, Ref. 5.

The results of a literature review show that the socially constructed gender-specific vulnerability of females lead to the relatively higher female disaster mortality rates compared to men; the disaster impact differ across economic class, ethnicity, gender and other factors; natural disasters exacerbate previously existing patterns of discrimination that render females more vulnerable to the fatal impact of disasters. The adverse impact of disasters on females relative to men vanishes with rising socio-economic status of women. However, more inter-disciplinary research is needed to fully understand the interplay between mortality and gender in the presence of natural disasters. More research is needed to fully understand why and how disaster strength interacts with female mortality.

120 long-living women have been studied in Ajara for the purpose of revealing bio-gerontological factors associated with longevity. On the basis of special ge­ron­to­logical questionnaire survey and the genealo­gical research it has been revealed that the absolute majority of the long-livers was in happy and long marriage, most of them had stable partners and were in happy and long marriage. There are early as well as late marriages among the long-livers. However, the women who marri­ed at the age of reproductive puberty (from 18 to 30 years of age) considerably prevail among them. It seems that having many children is not directly associ­ated with longevity. The correlation between late child­birth (over 40 years of age) and longevity was also shown. At the same time, the women having had their last delivery over 40 are distinguished by stronger health and high rate of longevity.

Medium size and polydispersion index, zeta-potential and particle distribution of hematite and magnetite micro- and nanopowders have been studied. The analysis proved that average size of particles is 740.9 nm for magnetite and 30-100 nm for hematite. Alter­native current power supply source has been created for hyperthermia. Proceeding from the task conditions U type MnZn magnetic conductors with cut out 10.0 and 8.0 mm wide gaps where glass tubes with magnetite and hematite suspensions are installed have been chosen. The series of experiments in conditions of different field stress and frequencies proved that for effective therapy of magnetic hyperthermia a compa­ratively powerful device with frequency up to 10 MHz is necessary in order to enable activation of Neel and Brawn mechanisms to achieve temperature 43-450C. On the next stage based on test material, for the first time in Georgia hyperthermia antitumor monotherapeu­tic effect and adjuvant action in tumor polychemio­therapeutic treatment was presented with the help of device “Lezi” designed by us. The experiments proved that in all three animals (white mice of three months) tumor growth cessation was observed and animals developed intratumor necrosis. Disease ulcerization was visually observed after 7 and 10 sessions which point the positive result of tests. Fig. 8, Tab. 2, Ref. 42.

The main tool of the analysis of efficiency of investment projects is discounting of the related cash flows, while main criterion of efficiency of the project the size of the net present value of these streams (NPV). Thus, as a defining factor of such analysis the rate of discounting (capitalization) of the project, representing the rate of discount corrected taking into account risk is conside­red. Considerable indicator of efficiency of investment projects is the internal rate of return (IRR) of the pro­fitability calculated connected with the solution of the equation of high degree. In work the method of its cal­culation on the basis of known computer system Matlab is offered and possibilities of practical appli­cation of this method are shown. Fig. 3, Ref. 3.

The paper represents business engineering as a method for building modern business that requires joint efforts of different professionals. It also requires adequ­ate changes in training personnel in order to set their activity as a common object to achieve in the process of learning. A process method of management is determi­ned as a single approach oriented on final product, in which separated processes with their sub-goals are subject to the final goal. We would like to underline that marketing and business-engineering disciplines inter­cross each other, and that marketing development provided origin of business-engineering. Ref. 2.

The prospects for the transition to hydrogen technology are discussed; it is shown that ecologically clean products must be correctly used in power engineering. It is noted that energy transfer losses by using electro energetic system are much more than when natural gas and hydrogen systems. Are shown is the advantage of flexibility at changes in the gas network in comparison with the electric network. Hydrogen accumulation is identified with the power accumulation and presence of water reservoirs. Fig. 1, Tab. 1, Ref. 4.

The air transportation in the world initially became the very first consumer of advantages of "e-commerce” and, now, “online” sale of air tickets makes the greatest share of all sales of the products made online. Howe­ver, sale of air tickets through the Internet has both positive aspects, allowing airline to receive additional incomes and to reduce expenses, and negative aspects – problems of the control and mana­gement of incomes of sales of the aviation product. For high-grade use of advantages of the Internet, airline should use such levers as computerized revenue management system and electronic distribution system that will allow to get big profit and benefit from the use of new high techno­logies and to avoid potential risks. Besides, applying programs of electronic commerce in the organizations of logistics processes, air carriers can essentially redu­ce as time of unproductive idle time of air courts for the earth, and to avoid financial losses.
