Currently, there is an insufficient number of studies on the low-level taxonomic diversity of orchids. This situation leads to the threat of implementation of measures to protect various species at multiple levels and may lead to their extinction. This is exactly the reason for the relevance of the present study. The goal of the study is to reveal the structural features of three populations of the orchid family based on indicators of density, ecological allocation, vitality, seed productivity, and the like. The leading approach to the study was the examination and comparison of various parameters of samples. The subjects of the study were individuals of three isolated populations of the Cephalanthera damasonium species. The study revealed a high level of vitality of one of the populations, due to the largest number. In addition, it was found that the age structure of the population forms the dynamics of development, and the highest seed productivity depends on the number and density of individuals. A common feature for all three studied populations is growth on the cinereous podzolized soils. At the same time, the content of calcium and other trace elements, CaCO3 and organic matter in the upper soil layers is substantially different. The content of such metals as nickel (Ni), lead (Pb), copper (Cu), cadmium (Cd) in the soils of the three localities of the studied populations is approximately the same, and the content of magnesium (Mg), manganese (Mn) and zinc (Zn) fluctuates.

The banking system plays an important role in the development and functioning of the country’s economy. The purpose of the study was to investigate and summarise the content of the banking system, considering its elements, functions, and potential for economic growth. During the research the following methods were used: theoretical generalisation, system approach, abstract-logical, and logical-analytical. The study examines the statements of scientists on the definition of the banking system from the standpoint of its legal basis and content. The composition of the elements of the banking system is considered in view of the objectively existing integration processes. It was emphasised that it is appropriate to consider the aspect of globalisation when generalising the essential, as well as the criterial features of the banking system. A study on the institutional and institutional-economic approaches to the functioning and development of the banking system. It was determined that the banking system is a sphere of procurement of a number of financial services and through its functioning and development effective levers of regulation are acquired. The study noted the features of the banking system must include the parameters of liquidity and financial stability, sufficient capitalisation, profitability, protection from internal and external risks and threats, financial and economic security, adaptability to the global, and macroeconomic environment. It is advisable to consider such structural features as the ratio of internal and external banking capital, the ability to develop in accordance with modern requirements in terms of information technology progress, information society, and digitalisation of business communications in generalising the essential features of the banking system. Further clarification of the criteria of the banking system will make provision for their identification at the level of each of its elements. The functions of the banking system were identified and generalised. The composition of the applied approaches to the essence of the banking system were expanded and supplemented with structural, security, and strategic ones. The integration of existing and new views on the concept, structure, functions, and role of the banking system in the economy allowed to develop an original position on the content of the concept of the banking system. Structural changes in the country’s economy have a significant impact on the functioning of the banking system. This, in turn, requires the identification of priority areas for structural reform of both the economy as a whole and the banking system, which, in fact, will be the subject of further research.

Modernization of the Ukrainian economy under the influence of global post-industrial trends mainstreams the priority of development of science-intensive, high-tech, innovative activities. Modernization creates the preconditions for strengthening competitive positions in the national and global markets. In modern conditions, the issue of assessing the competitiveness of catering companies is relevant. High competitiveness of the enterprise is the main condition of its activity and development. The purpose of the study is to assess the competitiveness of catering companies in the market of catering services in Ukraine. The study proposes methodological approaches to assessing the competitiveness of catering companies. Methodological approaches include continuity of monitoring, determination of parameters, indicators and criteria, selection of optimal evaluation methods. In the process of research the following methods were used: sociological survey, simple ranking, integrated assessment and factor method, system approach method. It was established that methodical approaches to assessing the competitiveness of catering companies include justification and development of a system of socioeconomic indicators and criteria (product quality, quality of service, quality and organizational staff, efficiency, efficiency of personnel management, price). Methodological approaches include a set of indicators that form an integrated indicator of competitiveness. This indicator allows to consider objective differences in the dynamics of enterprises, the conditions of use of available resources in the process of forecasting and development of enterprises. A comprehensive diagnosis was carried out based on an integrated indicator of the competitiveness of restaurants on special orders (catering), during which it was determined that its level has a significant differentiation according to the indicators of the studied enterprises, which are due to both external and internal factors, which allows the development of strategic priorities and specific measures to develop the image of the enterprise and increase its competitiveness

The COVID-19 pandemic has caused problems in all sectors of the world economy. There is no doubt that the pandemic will have far-reaching negative consequences for the world economy, including Ukraine. It is established that in January-September 2020, exports of Ukrainian goods decreased by almost 6%, imports – by 19%. Exports maintained large harvests of grain and oilseeds. Monitoring of changes in trade policy in the context of the spread of COVID-19 allowed to identify groups of countries that have introduced restrictive measures in trade policy: in 24 countries no export-import restrictions were introduced, in 19 countries indirect measures were implemented to protect the economy. To offset the negative effects on business, governments are developing aid packages to support it. These are mainly the following instruments: loans at reduced rates, the grace period for the payment of tax liabilities, cash grants. It was established that only some developing countries impose temporary foreign trade restrictions to avoid shortages in the domestic market. Most countries use other economic incentives to mitigate the effects of a pandemic. Ukraine is implementing economic measures and temporary trade restrictions to counter the pandemic. In particular, the Government of Ukraine introduced temporary restrictions on exports with the establishment of a zero quota for alcohol, buckwheat and anti-epidemic goods. The alcohol export ban not only did not worsen the situation on Ukraine's foreign markets, but also marked almost triple their extension. The embargo on buckwheat and grain exports from Ukraine has tripled imports. Despite the embargo on exports of anti-epidemic goods, trade did not stop, but even increased significantly for some commodity subheadings. The results of the study allowed to identify measures to mitigate the effects of the pandemic in trade and economic cooperation of Ukraine on the international arena

An analysis of the results of modern studies on the importance of clinical and pathomorphological factors as predictors of feline mammary tumours is presented. The urgency of the problem of predicting the development of cancer in this species is conditioned by the possibility of their use as biological models in human medicine, high level of incidence, significant share in the distribution of malignant types of tumours, and controversial issues of etiology and pathogenesis. Despite significant developments in the study of causal relationships with regard to mammary neoplasms, the use of different methodological approaches to assess the quantitative and qualitative characteristics of tumours, often in combination with insufficient sampling in groups does not allow to objectively assess the degree of malignancy and invasive potential both in a particular animal and in a group of patients, and therefore – to predict their behaviour. Generalization of available information on the peculiarities of the clinical course and pathomorphological changes in mammary tumours is necessary for further formation of a unified register of neoplasms in cats, which will be the basis for better understanding of the mechanisms of carcinogenesis, identification of promising biological targets, development and clinical implementation of pathogenetically based effective protocols for the treatment and prevention of cancer in cats. The lack of a unified approach to the verification of neoplasions makes it difficult, and in some cases impossible, to use cancer such predictors as histologic type, tumour size, clinical stage, angio- and lymphoinvasion, patient life expectancy and recurrence-free period as independent predictive factors. A large amount of clinical material has been accumulated, mainly presented in a descriptive form, without correlation with other causative factors. Along with the indicated predictors of carcinogenesis, in recent years, the role of cyclooxygenase-2 expression in the mechanisms of development and progression of feline mammary tumors has been actively studied, the influence on which allows obtaining a complex (multidirectional) therapeutic effect. Prospects for further research are the unification of clinical and pathomorphological diagnostic criteria and the establishment of a database of cats with cancer.
