The existence of international agreements of social security rights regulate the transfer, from one state to another contracting state, of health and social security rights. Although they have existed for many years, the application of the so called, the convention on social security, and the rights derived therefrom, have not yet sufficiently taken root in the work of medical institutions, they represent ignorant and ignore their application. Some medical institutions have greater experience in obtaining benefits from service provision by contracts, but they also have reserves and unused potentials. The provision of services to foreign insurance consumer can be equated with the export of health services, which is given in a domestic institution. The benefits of providing services under international agreements also have a foreign insured person in need of the service, a health institution that receives a new consumer, and health insurance, which can indirectly and sometimes even cheaper, cover the insured event. The aim of this paper is to point out the need for an active approach to the provision of services to foreign policyholders, as well as to implement the contract in the most efficient way possible, and to achieve benefits for the institution and for the service user.

This article discusses the properties of concrete composite materials based on their contexture. Systematic and interactive approaches are required in order to achieve optimal material properties in the preparation of composite materials. In order to predict the physical and mechanical properties of each component of the composite material but also as a whole, its optimization, not only the mechanical but also the material properties under different working conditions, requires a combination of different methods and technologies. The advantage of each composite is its specific properties that cannot be achieved by any component of the composite material alone. The strength of the materials based on polymer concrete mixtures can be compared to the strength properties of metals. On the other hand, this material has elastic properties which give the material a high degree of flexibility. When compared to conventional materials, the value of polymer composites is assessed not only in terms of excellent mechanical properties but also in terms of their low weight and cost. The aim of the paper is to describe the advantages and disadvantages of composites based on polymer concrete mixtures.

The paper examines the current state and the possibilities of using contemporary approaches and tools in HelpDesk systems development with the aim to examine its disadvantages. Disadvantages are accurately analyzed and the paper gives clear guidance how to eliminate them. It has been noticed that current design and development approaches have their own advantages and disadvantages. The application of the unified approach that combines the best individual characteristics of the existing approaches enables development of an automated HelpDesk system that is capable of expanding its own expertise. By combining unified aspect approach with the zero tolerance model driven approach, a new innovative approach to the development of a wide range of expert systems is obtained. This innovative approach is characterized by the highest possible degree of modularity. The application of the aforementioned approaches has also enabled expansion and improvement of the existing expert systems used for servicing numerous companies operating in various fields of business.

Political and economic aspects of every country are interconnected and conditioned by each other. The distribution of national sovereignty in all its aspects depends on their balance, short-term goals and long-term visions. Joining the processes of European integration for a country such as Great Britain was a challenge in direct contrast with a strong sense of national identity. Economic development in the single market in the Old Continent attracted the United Kingdom to join the European Communities in 1973 and thus partially sacrifice its national identity for the benefit of economic growth. However, the feeling of uniqueness and orientation toward the Anglo-Saxon tradition in a political and cultural sense caused the constantly lingering Euroscepticism. Global recession and the need for strengthening mutual solidarity in the European market will intensify the reconsideration whether joining the Union was the right decision. Internal political relations, on their own part, contributed to strengthening the campaign against the membership. A referendum was held in 2016 and the British decided that they still wanted to go their own way. From the point of view of economic welfare, this does not seem to be a rational decision. It is evident that after more than four decades a balance between political and economic goals is regained, this time in favor of national identity, although at this moment, a bystander does not see the political justifiability of such decision. A part of British society appears not to see it as well, so the exit process is slow and unpredictable, and the signs of reconsidering the exit decision are also appearing. The only thing that we can claim, with certainty, at this moment (November, 2019) is that nothing is certain. According to the European Court of Justice, The UK can withdraw their decision about leaving the EU at any moment. Such decision should be the topic of deeper strategic analyses, and not short-term political goals. If we were to analyze the foreign policy relations of the Kingdom through history, we will conclude that such an important decision was not made only on the basis of domestic policy dissatisfaction, but that there are some strategic reasons behind it. It is important to know that if the withdrawal from the EU was really to happen, if it will be with or no deal. Economic facts argue for reaching a deal, because while sovereignty and national identity are important, the economic strength determines a political position on the international scene. However, from a purely economic point of view, the best solution is that there is no withdrawal from the UK at all. The ultimate political and economic effects for both sides will depend on the final recomposition of geopolitical and economic relations which are in progress.
