THE EUROPEAN COUNCIL AND THE COUNCIL OF THE EU - PAST, PRESENT AND FUTURE

David Ramiro Troitino

Abstract
The European Council and the Council of the European Union are two of the main institutions of the European Union. The first holds the political powers of the organization, being fundamental in its development and deeper integration as all the Treaties need its approval. The second, the Council of the European Union is the main actor in the European Union, as its role inside the organization is the most influential. Both organizations represent the member states, and traditionally have been a stronghold of the intergovernmental side of the EU. Currently both still play a crucial role in the organization, but they are losing ground to other institutions based on federalism or neofunctionalism, like the European Parliament or the European Commission. The future of the Council will mark the future of the Union, and hence it is primordial to reform the institutions to face the new challenges of the XXI century.

MULTICRITERIA DECISION SUPPORT-APPROACH AND APPLICATION IN THE FIELD OF MATERIALS SCIENCE

Nikolay Tontchev, Zoran Čekerevac

Abstract
The research will focus on creating opportunities for prediction of mechanical properties as a function of the chemical composition and the heat treatment parameters taking into account the appropriate boundary conditions. The solutions for predicting properties as a function of the composition and the processing parameters are defined for specific customer requirements. This is accomplished by numerical procedures that determine the optimal composition for a number of criteria with established advantages for the significance of the results. The accuracy of the solution is determined by the reliability of the used experimental data. The actuality of the research of predicting the properties of materials is determined by the fact that the established models are based on computer simulation for building contemporary design tools. The practical results are applicable and they can be used for: a) the design of more efficient compositions in terms of the expensive alloying elements while maintaining the basic properties above a given threshold, b) evaluation of the technological cost of equally applicable technological variants of varying degrees of doping steel, c) determination of a rational representative of a certain class of materials best suited to the requirements previously set (most often controlled properties) among the rest of the class.

INTELLECTUAL MIGRATION AS AN ISSUE OF CONTEMPORARY EDUCATION IN UKRAINE

Oksana Abreu Bastos, Vladyslav Koshulko

Abstract
This article discusses the causes and consequences of intellectual migration, brain drain, or the migration of Ukrainian scientists and educators from Ukraine. Causes for brain drain are: lack of reforms in education and science; low public spending on science and education; no conditions for work; the artificial obstacles for obtaining foreign grants and scholarships; no material and housing conditions; no moral or psychological freedom; no decent wages. Consequences of brain drain are: lack of reforms in the state; the significant lag in education, science, and in socio-economic and cultural areas; isolation from worldwide innovation and progress; political and socio-economic crisis; loss the status of the scientific country. Also this paper examines the dynamic of the reduction in the number of scientists from 1990-2012. The conclusions of the study are assumptions about the negative consequences of the current situation in the Ukrainian education and science system for Ukraine's future. We are sure that only real and consistent reforms of science and education can protect the Ukrainian system of education and science from irreversible processes. The country needs real reforms that could accumulate the human capital of Ukrainian scientists and educators through the creation of reasonable living and working conditions for them inside the country, not abroad. Otherwise, Ukraine could lose its status as a scientific state.

WINNING TEAM CREATION IN CRISIS CONDITION: CASE STUDY OF PROFESSIONAL BASKETBALL CLUB

Mario Bogdanović

Editor’s note:
Team sport success is defined by combination of factors: psychophysical state of the players (cognitive, emotional-motivational and corporal), social factors (team cohesion, interpersonal relationships on the relations: management staff-coaching, staff-players, the players between themselves, sometimes the relationships with the public) as situational factors (elements of competitive situation). All of this mentioned factors can decide between victory and defeat in the competitive situation. Management of sport team is especially important in crisis situations (acute result crisis), and for its resolving it is extremely important to diagnose the causes, accept the facts, communicate the problem and in resolving the problem involve all the club members, this means the adaptation of Action Research methodology. So in every efficient management consulting it is needed to determine key problems (by gathering and analysing the broader spectrum of information, identify the causes of the problems and define and conduct the therapy). With such a procedure can be crated the model for resolving the crisis situations in the sports clubs. So this paper present a model for resolving crisis situations in sports teams on the example of one professional basketball club in Croatia. The crisis was solved by crisis identification by variety of measuring instruments and procedure and then followed elimination of its causes. The problems of management staff (N=3), coaching staff (N=2) and players (N=25, seven seniors and eighteen juniors/cadets) were first identified, and then corrective activities were undertaken to overcome the crisis. After the acute phase of the crisis was terminated, the club management was consulted in terms of human resources management (recruitment, selection, evaluation of performance and potential, promotion to player positions, motivation and rewarding with an individualised approach to each player) and then some structural interventions were suggested (both in the senior team and the supporting junior/cadet team). This work resulted in the presented model (procedure) for solving not only acute crisis but also structural problems in the sport teams.

ENSURING OF INFORMATION PROCESSES’ RELIABILITY AND SECURITY IN CRITICAL APPLICATION DATA PROCESSING SYSTEMS

Valery Lahno

Abstract
The system approach to solving problems of information security, proposed in this work provides for the integration of mathematical models of the processing and protection of information. This model connects invulnerability and flexibility for each of three aspects of security (confidentiality, availability and integrity) of information based on structural unification of these contradictions. The method of modeling the security policy (SP) to provide a highly reliable information processing (HRIP) has been developed. This method differs by using a new problem-based graph-theoretic unit of standard model of the protected automated system for connection flexibility the discretionary model with the principled security of models of the final states of the SP. The mathematical models of synthesis of policy safe interaction of information processes, allowing SP to consider separately the various structural components of network with the ability to its further interlinkages have been developed. Using the new mathematical models of flexible reliability, availability, confidentiality and integrity of information processed, allowing mathematically describe the mechanisms to ensure the availability and confidentiality of the information and take into account the quantitative requirements for data integrity.

THE BASIS OF MAKING THE STRATEGIC ALLIANCE BETWEEN COMPETITORS

Anna V. Kozachenko, Liliya Y. Shulzhenko

Abstract
The strategic alliances between competitors are principally known, but are researched insufficiently. There are no answers for such questions: if the competition emerges in the strategic alliance? If it emerges, how such alliance exists. There are answers for given questions in the article. Such answers are based on the results of experience analysis for known in the world business strategic alliances with partners, which are competitors. The answers are the following. It is shown, that the successful interaction between partners in strategic alliance of researched type is possible in the case of avoiding of direct competition. Competition in the strategic alliance between its participants emerges in the situation while they are the real competitors because of intersection of their interests on the same market. The successfulness of such alliance depends on fact, if the alliance participants are the real competitors or they are pseudo-competitors. If the competitor is real, there is no sense to make the alliance with him or it is necessary to be very careful. The basis of such alliance successfulness is the balance of partners’ interaction. Such balance describes the situation when, at first, achieving the goals of partners’ interaction is strategically important, at second, the volumes of interaction are the same for both partners. The pseudo-competitors are the economical agents, which make the production with the same purpose, but for different customers. Despite the production sameness the partners’ interests about the production promotion on the market do not intersect (implicit, but significant differences in customers’ needs and demands, that emerge because of natural (prices) or artificial (agreement about the market sectioning) way).There are high chances for the win of every participant in the strategic alliance with the pseudo-competitor. Such win is presented as the effect from partnership. The mutually beneficial co-work is possible between pseudo-competitors in alliance. Such co-work is the consequence of coincidence the alliance participants interests. The effect of partnership is presented as the win of every participant in competitive struggle with real competitors because of having the advantages from the participation in the alliance.

MONTE CARLO SIMULATION IN INTRALOGISTICS

Branko Davidović, Duško Letić, Aleksandar Jovanović

Abstract
One of the tasks of the intralogistics services is to help the development of the production process timely, i.e. to provide the continuity of production. This requires, among other things, the harmonization of production rhytms and the transporting-manipulative equipments' work cycles. In them, the process of transport runs and is organized so the material is delivered to work positions two to four hours before the processing starts, and taken away two to eight hours after the processing has been finished. This analysis has multiple aims. First, we should determine which number of transporting equipments would minimize the total costs. Further, when making this decision, we don't want to experiment in reality but on the model, in advance, before engaging ourselves in investments, i.e. before the transport has been realised and the technology and the organization of the working system engaged. In that respect, our aim is to shape and analyze more and less expensive variants of the solution with relatively short realization deadlines. Finally, we need a procedure which will be accessible and useful to the project engineers of the technological and transporting processes in intralogistics.

POSSIBLE APPROACH TO PROTECTION OF CRITICAL INFRASTRUCTURE ELEMENT IN TRANSPORT SECTOR

Dagmar Vidrikova, Kamil Boc, Katarina Škatuliakova

Abstract
Transportation infrastructure belongs between the most important economic elements of every government. It provides exchange of goods and services, participating by considerable degree on generation of GDP. Every disruption of transportation infrastructure causes financial losses. It paralyses the economy on local, regional or national and transnational level. Road bridges belong to the important elements of transportation infrastructure. Those belonging to highway network or European road network are of especially significant importance. Every damage or disruption of such element results in partial distortion of goods exchange system (truck transport), which damages the economic interests and relations on individual levels of government administration. Possible solution for prevention of, particularly, deliberate attacks on these elements, is their protection. This article contains the proposal of possible approach to protection of road bridge as an element of critical transportation. The approach featured in it is applied to model referential object (protected object) and therefore the data which are used in the proposal have only the illustrational character.

RELATIONSHIP MARKETING AS AN EFFECTIVE STRATEGY GUIDELINES AND A GUARANTEE OF SUCCESS IN THE BUSINESS OF A MODERN COMPANY

Ratimir Jovićević, Vladimir Ivanović

Abstract
Starting from the limited management and marketing mix as a dominant previous practice, the emergence of relationship marketing presents distinctive paradigm of marketing evolution, moving towards development of integrated relationship management, with more or less well-known customers. Relationship marketing actually comprises all the marketing activities that are directed towards the establishment, development and maintenance of successful relations of trade. Indeed, traditional concept of marketing (4P + 3P) is becoming less efficient with new conditions of global economy and new competition conditions of cross-linked economy and markets. Therefore, the new concept of relationship marketing between companies, their customers and other stakeholders that are important for the overall marketing efficiency was born. That is a new approach not only to marketing, but also to management generally. Relationship marketing can be considered as an effective strategy leading company in the new millennium. There are two key innovations. The first one only touches the new approach to management and marketing, while the second one significantly goes into the detail about the organizational innovation and new structure of company, which is now not limited only to the marketing function, but affects all the other functions in the company. Relationship marketing presents the activity of harmonization of business strategies, organizational structure and company culture, information about clients and information technologies, with the objective of continuous satisfaction of client’s needs and achievement of business benefits and profits. The new marketing concept is concentrated on understanding of customers in all aspects. Here marketing focus moves from classical instruments and business orientation to customer orientation, value and service dimension, with strong backbone in long term customer relationships. The cycle of the marketing value of products and customers is reflected in the fact that the product value drops over time, while the customer value grows over time.

THE ROLE OF THE STATE IN THE RENEWABLE ENERGY MARKET DEVELOPMENT IN UKRAINE

Olexandra Bulana

Abstract
Renewable energy development is one of the possible solutions to avoid dangerous climate changes and energy dependence. That is why many countries introduce a variety of incentives to attract investments in this sector. The aim of this article is to analyze impact of the Ukrainian state policy on the national renewable energy market. We questioned whether Ukrainians governmental interventions into this market have been successful. We also outline the influence of such incentives on the volume of investments, renewable energy capacity building, as well as on the competition at the market. The research has shown that Ukrainian government has implemented a number of tax and tariff incentives, which gave an impulse for rapid development of the sector. On the other hand, the rules for obtaining subsidies currently contain some risks for competition in the renewable energy sector. We came to the conclusion that despite some significant technical and administrative barriers, governmental incentives for renewable energy represent a rare case of successful subsidies in Ukraine.
