Purpose: The study of exogenic and endogenic factors influencing the state and development trends as for Ukrainian foreign trade in metallurgical products. Methodology: Analysis and synthesis methods were used to study the complex influence of internal and external factors on the development of Ukrainian metallurgical product export. To identify the volumes, structure and specific features of post-crisis renovation of economic dynamics of demand for metallurgical product in regional markets, the following methods were used: statistics, logical and historical methods; system generalization method allowed us to define the key issues in the development of foreign trade of metallurgical products. Findings: It was established that in connection with destructive influence of the recession in the countries consuming metal product there a significant drop in external demand for metallurgical product by domestic enterprises, introduction of a range of limitations in the market of Customs Union member-states, including the Russian Federation has been observed. Among the internal factors of metallurgical product export destabilization in mid- and short-terms, the following can be pointed out: destruction of production base of metallurgy and related branches caused by military operations in the East of Ukraine; high level of uncertainty concerning heavy industry, depreciation of national currency, financial instability, the threat of blocking the access to Mariupol and Berdiansk ports in the Azov Sea for the needs of both domestic economy and foreign trade. Prospects of product diversification, including increased volumes of supplies to the markets of EU member-states, one can see in the introduction of autonomous preferences for the Ukrainian exporters by the EU, with their further prolongation in case of full ratification of the Association Agreement between Ukraine and the EU. Originality: The key trends of metallurgical product foreign trade in Ukraine were further developed; the relevance of domestic export development to the global trends under recessive demand was grounded; systematization of determinants influencing the foreign trade of metallurgical product was improved by dividing them into internal and external. Practical value: Identification of key factors hindering the foreign trade of metallurgical product allows determining the potential of maintaining metallurgy as a budget-forming branch of the Ukrainian economy and a large source of currency returns. Systematization of risks allows us to optimize regulatory measures of support for this branch, and to determine the possibilities of state sectoral and institutional instruments for furthermodernization and increase in international competitiveness.

The infiuence of molecular rotation on the volume dependence of thermal conductivity in liquid nitrogen was evaluated. A modified method of reduced coordinates has been used to calculate components of the isochoric heat capacity of liquid nitrogen. A difierence in the behavior of temperature dependences of the Bridgman coeficient at pre-crystallization temperatures in liquid Ar, CH4 and N2 is explained by the infiuence of rotational motion of molecules © 2015, Ivan Franko National University of Lviv.

Thermal conductivity of solid cyclopentane C5H10 has been measured at isochoric conditions in the plastic phases I and II for samples of different densities. Isochoric thermal conductivity is nearly constant in phase II and increases with temperature in phase I. Such behaviour is attributed to weakening of the translational orientational coupling which, in turn, leads to a decrease of phonon scattering on rotational excitations. The experimental data are described in terms of a modified Debye model of thermal conductivity with allowance for heat transfer by both low-frequency phonons and diffusive modes. © 2014 Versita Warsaw and Springer-Verlag Wien.

Purpose. To investigate the genesis of the network economy concept and theories of transnational corporations development on the basis of different methodological approach; to define theoretical base of analysis of network structures and peculiarities of their forming under globalization conditions; to reveal the main trends of the world retail trade development using the international organizations research. Methodology. The method of analysis and synthesis was used in order to investigate the actual approach to analysis of network structures and the essence of transnationalization of business in the field of international trade. A method of combination of logical and historical was used for the analysis of organizational forms of network business. A method of system generalization allowed us to define the key trends of the world retail market development. Findings. It was defined, that the network economy was formed in the process of settling of the global and informational economy. The network economy is related not only to the development of information technologies, but also to the network business forms. Network structures are widespread among transnational corporations in the field of international trade, especially in its retail sector. The world retail trade can be described by an increased interest from international operators and in the nearest years it will remain one of the most perspective trends for investing. Value and practical implementation. The article will be of interest to researches of transnational corporations in the field of international trade, especially in its retail sector and also to those, who study the reasons of expansion of these companies into the international markets and investigate the forms of network structures' organization in current conditions.

Introduction. Being in the regulatory field of WTO and implementing the Deep and Comprehensive Free Trade Agreement with the EU, Ukraine defines foreign trade in agricultural products among the priorities of national economic development, which is fully justified due to the existing potential, and the possibility of its realization. In this context, the problem of adequate business and informational environment creating to ensure free access to foreign markets and stable trade flows of competitive products is actualized. Purpose of the article: comprehensive analysis of measures regulating foreign trade in agriculture, evaluation of state support for agriculture effectiveness in some countries of the world and suggesting directions of Ukraine's regulatory policy improving in this area. Results. Modern regulatory policy in the sphere of foreign trade in agri-food products is defined as a set of actions of the governments aimed to create preconditions for the effective implementation of business activities taking into account the factors that influence flexibility, legality, equality, transparency and balance between the interests of the state and society. It should effectively combine the task of the agrarian sector development at the national scale with the requirements of international institutions, major trends of international trade, the current state and prospects for changes in the world's food market expected conditions. Regulatory policy should include measures to ensure food security and protect the domestic market, promote export and improve its structure, as well as support domestic agricultural producers. Comparative analysis of tariff and non-tariff measures of agricultural foreign trade regulation in the US, EU, Russia and Ukraine has shown significantly higher rates of duty for agricultural products compared to non-agricultural products. Significantly lower levels of tariff protection for agri-food products in Ukraine compared to many trade partners were identified. Extensive use of non-tariff measures by developed countries under conditions of their limited use by Ukraine is taking place. Bearing in mind the issue of limited funding opportunities of Ukraine, the aforementioned fact complicates implementation of policies aimed to improve competitiveness of the national economy within the framework of full membership in the WTO. Analyzing the impact of the state support on agriculture by OECD methodology in the US, EU, Russia and Ukraine, it was concluded that Ukrainian agricultural support policy is characterized by the lack of stability and ineffective implementation of budget support programs. Export stimulation and improvement of Ukrainian products' quality and competitiveness in foreign markets can be realized through measures of foreign trade regulatory policy targeted to facilitation of access to foreign markets and improvement of producer's support, which, inter alia, includes informational, financial, institutional support and the internal market protection measures. Conclusion. The generalization of the world experience in the regulatory policy's formation and implementation followed by evaluation of its state support for agriculture, allowed developing strategic directions of Ukraine's regulatory foreign trade policy in agriculture improving, which are combined with the international treaties and national regulatory institutions and based on access to foreign markets improving, financial, institutional and informational support, protection of the agricultural domestic market, export stimulation and optimization of its sectoral and regional structure. Implementation of the proposed measures will improve regulatory policy in foreign trade and quality competitiveness of domestic agricultural products in the world markets. © Institute of Society Transformation, 2015.

Considering the world demographic situation, especially the role of nutritional factors in the pathological aging process, geronto-dietetics has become an independent branch of science. However, food assortments for elderly people are currently insufficient in diversity and amount. Geronto-dietetics production is based on increase in useful substances to the level consistent with physiological consumption rates of the elderly (15-50% of daily requirement). The study of senescence discovers the symptoms of aging which reveal age-related changes in functional systems. For over 100 years the scientists have known about the connection between aging and the state of thyroid gland. The physicians diagnose elderly hypothyreosis at 99%. To prevent hypothyreosis in the elderly one should improve iodine and selenium deficit by increasing food share containing fruit and vegetable sources of selenium and antioxidant vitamins.
