The article describes the acme-cultural approach as a modern paradigm for improving the training of physical education and sports specialists. In the context of highlighting the general provisions, the potential of the acme-cultural approach is emphasized as an important factor in the formation of behavioural aspects of a professional, his professionally relevant qualities,, the definition of a specialist as a subject of culture, its main actor, which overall ensures an increase in the level of social success of the future specialist, his competitiveness on the labour market, personal expression, self-development, and self-realization. According to the authors, the acme-cultural approach allows for the solving of a problem of a uniform space of humanitarian and naturalistic and scientific forms of culture in physical and sports education thanks to the understanding of the subject-object dualism that is inherent to them within the meaning of the phenomenon of professional culture.

W artykule opisano podejście kulturowo-kulturowe jako nowoczesny paradygmat doskonalenia treningu specjalistów kultury fizycznej i sportu. W kontekście uwypuklenia zapisów ogólnych podkreśla się potencjał podejścia acme-kulturowego jako ważnego czynnika w kształtowaniu behawioralnych aspektów profesjonalisty, jego cech istotnych zawodowo, definicji specjalisty jako podmiotu kultury, jego główny aktor, który w kompleksie zapewnia wzrost poziomu sukcesu społecznego przyszłego specjalisty, jego konkurencyjność na rynku pracy, ekspresję osobistą, samorozwój, samorealizację. Wyraża się opinię, że podejście kulturowo-kulturowe pozwala na rozwiązanie problemu jednolitej przestrzeni humanitarnych i przyrodniczo-naukowych form kultury w kulturze fizycznej i wychowaniu sportowym, dzięki znajomości tkwiącego w nich dualizmu podmiotowo-przedmiotowego w rozumieniu zjawiska kultury zawodowej.

Commercial flame-retardant additives based on Sb2O3 were evaluated. It was found that they have an acceptor, thermostabilizing and flame-retardant effect on PVC linoleum. Based on IR spectroscopy, DTA analysis, diffraction, and X-ray fluorescence analysis, it was found that one of the samples contains 100% Sb2O3, while the others contain microcrystalline CaCO3 (50-95%) and other compounds, e.g., organochlorines and hydrocarbons. The flame-retardant mechanism of PVC linoleum consists in the synergistic action of Sb2O3 and CaСО3 by binding gaseous hydrogen chloride formed during the combustion and thermal decomposition of PVC.

Zbadano handlowe dodatki uniepalniające na bazie Sb2O3. Wykazują one działanie akceptorowe, termostabilizujące i uniepalniające na linoleum z PVC. Na podstawie spektroskopii IR, analizy DTA, dyfrakcji oraz analizy fluorescencji rentgenowskiej stwierdzono, że jedna z próbek zawiera 100% Sb2O3, natomiast pozostałe zawierają mikrokrystaliczny CaCO3 (50-95%) oraz inne związki np. chloroorganiczne i węglowodory. Mechanizm uniepalniania linoleum z PVC polega na synergicznym działaniu Sb2O3 i CaСО3 poprzez wiązanie gazowego chlorowodoru powstającego podczas spalania i rozkładu termicznego PVC.

The paper examines the impact of protective equipment used during the COVID-19 pandemic on the environment. The impact of protective face masks on the aquatic environment was analyzed in more detailed way. The amount of protective face masks penetrated into the environment as a result of the COVID-19 pandemic and their role in the increase of plastic and microplastic things in the environment was noted. The aim of the work was to study the migration of a number of metals from disposable protective masks into the aquatic environment in the short term. Using the method of atomic absorption spectroscopy, the value of Cu, Pb, Mn, Zn, Fe in the investigated model systems containing protective disposable face masks was obtained by varying the pH of the aqueous medium. It was found that for manganese, lead and iron there is a permanent (Mn) or temporary (Pb, Fe) excess of these metals in the aquatic environment according to national and European standards. The probable possibility of sorption effects and the need for further research in this direction were noted.

Ukraine is an aviation state that has a full cycle of development and serial production of aircraft, commercial operation of civil aviation, training and retraining of professionals for the industry. The level of development of air transport determines not only the country's image, but also the sustainable development of its national economy. The article presents a structural analysis of the trends in the development of world aviation transport, as well as the economic development of aviation transport in Ukraine and its infrastructure. The authors pay special attention to the study of the factors of the seasonality of air transportation and their influence on the results of the operational activities of air transport in Ukraine.

The analysis of anthropogenic factors influencing the state of natural water is carried out in the work. The need for a detailed study of the impact of urban areas on river water quality is noted. The study of the state of one of the main rivers of Poltava region in the area of about 100 km during the winter-spring period on the parameter of mineralization. The influence of individual settlements on the water status of the Vorskla River is considered. There was a gradual increase in river water pollution in the studied area and an increase in mineralization from 660 to 820 mg/l (February) and from 500 to 580 mg/l (April) (Sr = 2%). It was found that the greatest anthropogenic impact on the state of the Vorskla River is in the area of Poltava - Novi Sanzhary. The influence of surface runoff on changes in surface and groundwater quality of Poltava region is shown.
