ABSTRACT
The pandemic and subsequent changes in various spheres of human activity have also transformed consumer behavior, particularly in the cryptocurrency market. The article is aimed at identifying the priority directions of transformations taking place in the cryp-tocurrency market in the conditions of the Covid-19 pandemic under the influence of certain groups of factors. System and network approaches to understanding the cryp-tocurrency market have been identified. The cryptocurrency market is considered from a functional and institutional point of view. From a functional point of view, the crypto-currency market is a set of economic relations in cyberspace regarding cryptocurrency mining, initial coin offering (ICO) and circulation of cryptocurrencies based on the laws of supply and demand. From an institutional point of view, the cryptocurrency market is a set of participants in virtual currency schemes who carry out cryptocurrency trans-actions. The following signs of cryptocurrency market segmentation are justified such as those depending on the market capitalization of the cryptocurrency;on the nature of the crypto asset's movement;on operations carried out on the market;on the region;on consumers of services. Factors that influence the functioning of the cryptocurrency market are systematized according to the following groups: macroeconomic, price, en-vironmental, geographic, market, behavioral and technological. The influence of gold, oil prices, the daily number of Covid-19 cases and deaths from Covid-19, the MSCI ACWI global stock index, the iShares MSCI All Country Asia ex Japan ETF, the Wilshire 5000 Total Market Index on the Bitcoin exchange rate is revealed. The trends in the crypto-currency market development in the post-war period are justified, namely the growth of investors' interest in cryptocurrencies against the background of the initial coin offer-ing collapse;growth of payments in cryptocurrencies;strengthening the regulatory landscape on a global and national scale;integration of the cryptocurrency market with traditional finance;attracting non-typical participants to the cryptocurrency business;expansion of participants in the infrastructure of the cryptocurrency market due to the rapid cryptocurrency market development, in particular, due to the production of equip-ment for its operation.
ABSTRACT
This paper examines construction technologies in the context of digitalization in the VUCA world, a dynamically changing stressful world that requires a quick response and adequate processing of impressive volumes of information. The restrictions introduced throughout the country in connection with the COVID-19 pandemic are shown, paralyzing the activities of many construction companies and organizations operating in the commercial real estate market. The technologies and models of adaptive management used in the event of problematic, crisis situations have been investigated in modern practice. The use of the technology of the enterprise's potential has been investigated, which makes it possible to develop a model for the development of adaptive management of the construction complex.

ABSTRACT
The article emphasizes the need for the application of Internet technologies in medical schools during the COVID-19 pandemic. The purpose of the article is to highlight the methodology and results of experimental work aimed at the verification of the effectiveness of using of Internet technologies in medical schools. The article is devoted to the questions of organizing online -learning for of medical students and verifying the efficiency of the suggested approach. The results of a survey of would-be doctors and junior medical staff are described. The research was conducted at Vinnytsia national medical university and medical colleges of Vinnytsia region in 2017-2020 years. The educational process in the distance mode encompassed distant classes of using educational blog Blogger, mental maps Mindomo and application LearningApps. At the primary stage of researching an insufficient level of professional knowledge and practical skills of medical students was determined. There were identified shortcomings in the process of professional training of future medical staff in the study of professional disciplines the traditional training and limited use of ICT in the educational process of medical schools. The empirical basis at the formative stage of the study included 247 students and 70 teachers of professional disciplines at Vinnytsia national medical university and medical colleges of Vinnytsia region. At the formative stage of the experiment students of the control group studied according to traditional methods, and their teachers of professional disciplines used traditional teaching technologies. Students of the experimental group studied according to innovative methods, and their teachers used Internet technologies. It was specified that future medical staff of the experimental group received better results, than the students of the control group and they have a higher level of professional knowledge. It has been found out that the use of Internet technologies in the research significantly improves quality and effectiveness of such training, brings the students closer to real clinical scenarios, enables them to enhance their practical skills clearly and qualitatively. The effectiveness the use of blogs, mental maps, and online exercises LearningApps in teaching professional disciplines to future medical staff was checked by conducting comprehensive assessment.The statistical verification also confirmed the effectiveness of the implementation of these modern technologies. The prospects for further research predetermined by the necessity to use the gained experience in organizing isolated distance medical learning at the studying of natural, socio-economic, and humanitarian disciplines in the difficult conditions of the war in Ukraine.
ABSTRACT
The aim of this study was to determine the hematological profile and specific immunity of laying hens with the addition of oil extracts of lycopene or astaxanthin to the diet. The study used High Line W36 chickens that were vaccinated against Newcastle disease, infectious bronchitis, avian rhinotracheitis and egg drop syndrome. It was found that the addition of lycopene (20 mg/kg) and astaxanthin (10 mg/kg) for 30 days did not affect the hematological profile of laying hens. Increasing the content of lycopene to 40 and 60 mg/kg or astaxanthin to 20 or 30 mg/kg of feed for 30 days reduced the number of leukocytes and hemoglobin in the blood compared to the control, which received an equivalent amount of refined sunflower oil in the diet. Lycopene and astaxanthin supplements, regardless of dose and duration of administration, did not affect the titer of antibodies to Newcastle disease, infectious bronchitis, avian rhinotracheitis, and egg drop syndrome in serum of vaccinated laying hens. The obtained data can be used to justify the optimal dose and term of feeding of lycopene or astaxanthin supplements in the development of a model of carotenoid enrichment of chicken egg yolks.
ABSTRACT
The article presents screening of Facebook and Instagram news pages for the degree of media literacy of modern recipients in the perception and further dissemination of information about COVID-19. We state that in most cases modern recipients do not check the information obtained from media sources (as confirmation, we present the results of an electronic survey). Nowadays most respondents do not pay attention to the information provided and are ready to repost the material on their social media pages. The data obtained confirm this thesis: 45.8 % partially 23.7 % fully do not check the information from media sources, therefore, almost two thirds of respondents trust the facts presented in media. We associate low media literacy with the rapid globalization of modern media, due to which the flow of information is uncontrolled, especially in Internet communication. Another reason for low media literacy is the "skill" of journalists to mislead recipients through bright headlines. It is proved that a bright headline, compositionally organized as an interrogative or exclamatory sentence, has a greater impact than a narrative construction. According to our survey, headlines with lexical manipulative resources are the most popular (44 %), while headlines with phonetic manipulative means are less affected by the recipient. Most of the interviewed recipients are still ready to check the factuality of the information in a media text (we emphasize that we have deliberately selected fake news). Some recipients (22 %) pay attention to fake news because of a bright headline (or trusting a verified media resource) and are ready to repost the news without verification. Due to the resonance of the news related to COVID-19 journalists have used not only objective but also fake news as a tool to influence the recipient. The questionnaire clearly indicates that media literacy of modern recipients is influenced by the political orientation of a media source, as well as the recklessness of recipients to verify the facts and trust any information obtained from official sources and interpreted in media.
