Документ Conceptual aspects of energy generation market development on the principles of sustainability(2024) Dykha, M.; Dykha, V.; Zyma, V.The article offers a conceptual vision of the development of the energy market based on the principles of sustainability, which should be characterized by safety, environmental friendliness, adaptability and stability, efficiency (including economic) and accessibility (including social), transparency. The importance of ensuring the adaptability of the development of the energy system due to uneven energy consumption throughout the day and throughout the year, stability, safety of energy generation, and transparency is substantiated, which will be facilitated, among other things, by the synchronization of the energy system of Ukraine with the energy system of continental Europe. The expediency of increasing the use of ecologically neutral sources of electricity, which is important for ensuring sustainable development, is substantiated . The possibilities and features of the development of energy generation from renewable sources are characterized, which include: solar, wind, hydrogen generation , the use of biogas, obtaining energy from household waste, as well as hydrogen and nuclear generation. Despite the ecological neutrality of solar and wind power plants, the need for disposal and processing of individual components at the end of their service life is described, the need to work out such issues in advance, which corresponds to the principles of sustainability. The adaptability of the operation of hydropower plants and their different productivity depending on the methods of using water energy are noted. The types of hydrogen production and the features of hydrogen generation are described, as well as the feasibility of developing biogas energy generation, which will contribute to the "smart" disposal of waste and the rational use of such resources. The dangers associated with nuclear power plants are summarized, the leveling of which will contribute to the safety and stability of their operation. Attention is also paid to types of energy generation that are not environmentally friendly (thermal power plants), which generate electricity by burning fuel (coal, gas). Their share in the energy-generating balance is decreasing, but today they still provide the necessary adaptability in the energy market. To ensure stable, adaptive, efficient operation of the energy market of Ukraine, it is important to ensure the diversification of generation; to maximally realize the potential for the use of renewable energy sources, to generate ecologically clean energy.Документ Foreign economic cooperation of Ukraine and Poland: status and prospects(Хмельницький національний університет, 2024) Dykha, M.; Dykha, V.; Konieczny, G.Документ Foreign trade activity of Ukraine and Egypt(Хмельницький національний університет, 2025) Dykha, M.; Dykha, V.; Elnashar, E. A.The article examines the state and trends of Ukraine's foreign trade activity. The authors analyzed the volumes of Ukraine's exports and imports, the balance of Ukraine's foreign trade balance. The full-scale invasion of the Russian Federation into Ukraine led to a significant decrease in Ukraine's foreign trade turnover. Ukraine's exports decreased from 68,07 million USD in 2021 to 36,18 million USD in 2023. Imports decreased from 72,84 million USD in 2021 to 55,3 million USD in 2022. In 2023, import volumes increased to 63,57 million USD. During 2021-2023, Ukraine's foreign trade balance deteriorated (from -4,77 million USD to -27,39 million USD). The geographical structure of Ukraine's foreign trade was studied. The share of Ukraine's exports and imports with the countries of Europe, Asia, Africa, America, Australia and Oceania has been determined. The volumes of Ukraine's foreign trade turnover with African countries are not significant, however, among African countries, Egypt is Ukraine's leading foreign trade partner. The commodity structure of Ukraine's exports and imports as a whole has been analyzed, as well as the volumes of foreign trade turnover between Ukraine and Egypt. The groups of goods that predominate in Ukraine's exports and the groups of goods that enter Ukraine have been determined. It is noted that Ukraine and Egypt have great prospects for the development of cooperation. Ukraine seeks to build friendly strategic relations with the countries of the African continent, based on mutual respect for basic values and international principles. Egypt is interested in economic cooperation with Ukraine in innovative areas, such as IT, supply of railcar products, transport engineering, etc. Egypt is a popular destination for Ukrainian tourists. The resumption of air flights from Ukrainian cities will contribute to the intensification of tourist relations. Prospects for the development of foreign trade cooperation, scientific and technical, and cultural interaction between Ukraine and Egypt will be the subject of further research.Документ Ринок праці: еволюційно-ретроспективний аспект наукових поглядів та сучасний контекст(Хмельницький національний університет, 2019) Диха, М.В.; Диха, В.В.; Dykha, M.; Dykha, V.У статті узагальнено наукові погляди щодо визначення ринку праці в ретроспективі та на сучасному етапі.
