Srem, as traditional farming, orchard and wine-growing region, faces the problem of shortage of water needed for agriculture. During the seventies of the last century brook valleys in the southern part of Fruska Gora loess plateau were intended to be dammed. Thus, artificial lakes could have been formed. It took long period of time to put these projects into practice and numerous projects have not started yet. After the dams had been built and lakes filled with water, planners faced hydro-geological problems at many locations. Nevertheless, these accumulations fulfill their primary function, i.e. they ensure water for irrigation and protect agricultural land from floods. There is a hydroaccumulation system, Calma lakes, near the village of Calma. Its primary function was to ensure water supplies for agriculture, but eventually it got new significance which can be noticed in fish raising and sport fishing development.

Abstract This paper describes the results of experimental investigation of the sample of the hydrogen-air gas generator unit with the expected average power of 65 kW. In total 5 test runs were made. Two tests showed that the mass flow and outlet gas temperature was in an agreement with the designed parameters. Additional attention should be paid to the cooling system design for the combustion chamber. In future such a gas generator in couple with the suitable gas turbine unit could be a part of the renewable energy accumulation system e.g. of hydrogen-air energy storage.

The article is devoted to actual issues of public finance – old-age income support and social security in the twenty-first century. For this reason, government has tried to guarantee old-age’s pension eligibility. In our country pension system is presented with three-level pension system, which join mandatory and voluntary components – solidary system (first level), compulsory accumulation system (not exist now) and private pension system. According to Ukrainian’s pension model, basic and minimum pensions are funded by solidary system or PAYG (“Pay-As-You-Go”) system. As the results, maintains of sufficient financial resources of Pension fund’s budget is very important for financial stability of pension system. The authors show the relationship between sufficient financial support for the elderly in Ukraine and the financial capacity of the solidarity pension system. It was found that in order to form a financially stability pension system, it is necessary to ensure a sufficient amount of own pension fund revenues and avoiding deficit of the Pension Fund’s budget. So, the main indicators of current PAYG system in Ukraine include the public pension expenditures and deficit of the Pension Fund. The article presents dynamics of revenues to the Pension Fund of Ukraine and structure of own pension fund revenues and allocations from the government budged. According to author’s research, the main source of revenue collection of the Pension fund’s budget in Ukraine is the budget’s transfers. О. Чеберяко, В. Бикова ISSN 2078-5860 ФОРМУВАННЯ РИНКОВОЇ ЕКОНОМІКИ В УКРАЇНІ. 2019. Вип. 41 480 The budget expenditures in the structure of income of the pension fund are also analyzed. The total amount of the government budget expenditures that are directed to financing the pension fund are about twenty percent. In our opinion, the key reasons of the “lack of own income” are the shadowing of the economy, the macroeconomic situation, the low minimum wage, the existence of a limit on the maximum amount of wages, which accrues percent of social contribution. As a conclusion, the authors suggest measures for solving the issue of “lack of own income” of the Pension Fund of Ukraine – rising the retirement age, labor market’s reforming, increasing insurance fees and implement compulsory accumulation system. The analytical materials and conclusions can be useful for following researches of finding solutions for achieving the financial stable Pay-You-Go system. Key words: pension system, The Pension fund, social insurance payments, deficit of The Pension fund, government budget.
