Item Cyclical Behavior and Connection between Recovered and Sick COVID-19 Patients Worldwide(Science and Engineering Research Support Society, 2020) Bludova, Tetiana; Блудова, Тетяна Володимирівна; Блудова, Татьяна Владимировна; Savchuk, Nataliia; Савчук, Наталія Володимирівна; Савчук, Наталия Владимировна; Skliar, Nadiia; Usherenko, Svitlana; Ушеренко, Світлана Василівна; Ушеренко, Светлана Васильевна; Verba, Pavlo; Верба, ПавлоThe article presents an approximation of the dynamic parabola of the ratio of serious and critical cases to the total number of patients with COVID-19 in the world with short-term prognosis. The purpose of the article is to study the statistical material and to search for patterns and relationships of indicators, which will help us understand the global trend of fight against the COVID-19. Gradual reduction of the number of critical cases is proven due to the development of new methods and implementation of strategies to defeat COVID-19 worldwide. The analysis clearly shows structure and correlation between the number of recovered patients and total COVID-19 patients in relative terms to the number of all infected by COVID-19 in the world, and this relationship is shown to be close and inverted. The cyclical nature of the behavior of such interconnections is proved, which testifies both to the natural and objective regularity. The proposed study results will help medics and government in all countries to better cope with the problem and prepare in advance for the outbreak of disease.Item Modelling the economic security of regional external trade flows(Baltic International Centre for Economic Policy Studies, 2017) Bludova, Tetiana; Блудова, Тетяна Володимирівна; Блудова, Татьяна Владимировна; Savchuk, Nataliia; Савчук, Наталія Володимирівна; Савчук, Наталия ВладимировнаSubject of research: assessment and management of economic security of regional foreign trade flows of regions of Ukraine. Methodology: during the research, statistical analysis and analytical analysis (in the study of the main aspects of the formation of foreign trade flows of the region) are used. Mathematical modelling in economics (when creating a model of the two-dimensional normal distribution of regional foreign trade streams) and methods of analysis for risk assessment, conditioned by the formalization of the uncertainty of the operation of regional foreign trade operations are also used. The purpose of scientific research: mathematical modelling in economics in the management of economic security of export-import flows of regions of Ukraine; analysis of the structure of regional foreign trade flows in Ukraine and their respective risks; creation of the field of economic security of foreign trade flows of the region. The conclusion of the research: the study of limits and quantitative analysis of the risk of regional foreign trade flows in some regions of Ukraine is reduced to the creation of the area of crossing the main splicing ellipses of two-dimensional normal laws of export-import flows of these regions. After that, it will be possible to make a comparative assessment of the competitiveness and economic security of the regions. The purpose of the article is to develop an economic-mathematical model of quantitative risk analysis and to find appropriate boundaries of foreign trade flows of the region, which allows setting the thresholds of regional exportimport operations for optimal management of the process of foreign trade flows of the region. The foreign trade flows of Ivano-Frankivsk, Mykolaiv, and Kherson regions of Ukraine based on a two-dimensional normal distribution are modelled. Areas of threshold values of indicators of foreign trade flows of regions from the point of view of economic risk are defined, which, in contrast to existing one-dimensional approaches, takes into account elements of the interconnection of foreign trade flows of the region. The methodical conditions for constructing split ellipses of foreign trade flows of the region for comparative estimation of the risk of competitiveness and economic security of the regions are developed. This will make possible to conduct a systematic analysis of the region’s economic development and to take measures both at the local level and at the state level in order to neutralize a number of threats to its economic security.Item Study of functional dependence of Ukraine budget deficit on Tax and other revenues(Forschungsinstitut der IWVWW, 2014) Savchuk, Nataliia; Савчук, Наталія Володимирівна; Савчук, Наталия Владимировна; Bludova, Tetiana; Блудова, Тетяна Володимирівна; Блудова, Татьяна Владимировна
