Документ Agroecological Assessment of Urboecosystems' Soils (Based on the Example of the City of Khmelnytskyi, Ukraine)(Świnoujście-Varna, 2018) Mironova, Nataliia; Biletska, Halyna; Rybak, Victor; Iefremova, Olha; Shevchuk, Nataliia; Shevchenko, Sergey; Artamonov, BorisW artykule jest oceniony stan gruntów w średnim wg liczby mieszkańców miejskim ekosystemie na przykładzie miasta Chmielnicki (Ukraina) na podstawie wskaźników agrochemicznych (kwasowość, wilgotność, zawartość próchnicy, elementy odżywcze, wapń, magnez, siarka), a także na podstawie zawartości ołowiu oraz stopnia zasolenia. Wyznaczono, ze dla średnich miejskich ekosystemów charakterystyczne są gleby o reakcji słabo zasadowej lub zasadowej, niskim zabezpieczeniu wody, słabą koncentracją mineralnego i wodorozpuszczalnego azotu oraz względnie wysokiej zawartości próchnicy. Grunty miejskie mieszczą wielką ilość fosforu, potasu oraz wapnia, w mniejszym stopniu – magnez. Zasolenie gruntów jak i występowanie ołowiu jest charakterystyczne dla terenów położonych przy drogach, nie przekracza to jednak dopuszczalnych ilościДокумент Evaluation of Educational and Methodical Support in Natural Science Training of Future Ecologists(2018) Diachuk, Andrii; Biletska, Halyna; Mateyuk, Olesya; Mironova, NataliiaThe article has been dedicated to the actual problem – an increase of efficiency of natural science training of future ecologists as a result of improvement the teaching and methodological materials. The aim of the study consists in evaluating quality of educational and methodological support of natural science training of future ecologists and to prove appropriateness of the outlined requirements for selecting the content of natural science training. For analytical evaluation the method of expert evaluations (surveys) was used. The work programs and e-courses of natural sciences in Modular object-oriented dynamic learning environment have been examined. To the evaluation teachers of natural sciences from the universities of Ukraine have been involved who have been training ecologists. To determine their competence and processing the survey results, the methods of mathematical statistics have been used. It has been determined that the overall level of quality of the work programs of natural sciences on a five point scale is 4,39, e-courses – 4,35. It has been found that the most significant indicators in the evaluation of the work programs are: the availability of the educational material in the content of the discipline that demonstrates the importance of natural sciences in the professional ecological activities; appropriateness of the discipline of educational professional program of preparation of bachelor specialty “Ecology”; modular structured educational material. During the evaluation of electronic courses the greatest importance have the following indicators: completeness and quality of diagnostic tools; electronic course content; the quality of informational teaching methodological materials. Since the indicators of the quality of educational and methodological materials have been selected on the basis of the set out in the study requirements for the content of natural science training of future ecologists, the importance of weight coefficients confirm the feasibility of the theoretical statements defined in the study about the selection of the content and structure of teaching material.Документ Parametric Assessment of Macrophytes Ecological Niches in Solving Problems of Sand Quarry Lakes Phytomelioration(Journal of Human, Earth and Future, 2022) Mironova, Nataliia; Mateyuk, Olesya; Biletska, Halyna; Shevchenko, Sergii; Kazimirova, Liudmila; Artamonov, Boris; Kravchuk, Vasyl; Bloshchynskyi, IhorTechnogenic reservoirs, i.e., sand quarry lakes, appear when sand is extracted under the water column by dredgers or as a result of flooding of quarries. Studies of such reservoirs in the territory of Small Polissia (Ukraine) have shown that the devastated shoreline is like a neo-ecotope formed in the ecotone zone between the water environment of such reservoirs and natural areas upon completion of their operation. Changes in the ecotope within this zone lead to the formation of ecological niches with a set of new specific factors characteristic of aquatic and near-shore vegetation. It has been determined that the fundamental niche of macrophytes in the littoral area of sand quarry lakes in the conditions of Small Polissia is determined by the following parameters: illumination 2500-90000 lux; depth 0–5 m; and trophicity (humus content) – 0-5 %. The realized niches differ for plants of different ecological groups and make up about 50 % for helophytes, about 20 % for pleistophytes, and about 70 % for hydatophytes of the fundamental niche of aquatic vegetation. The volume of space in which the niches of all types of macrophytes in the technogenic lakes of Small Polissia overlay is 10%. The maximum overlay of niches is characteristic of areas covering a combination of factors in terms of illumination (in summer) 15000-90000 lux and depths of 1.3–2.8 m, which creates conditions for the formation of three-tiered phytocoenoses. The niche of submerged plants is the largest, which indicates their highly competitive potential, which is limited mainly by the illumination parameter. Under such conditions, the rapid development of submerged vegetation in the future may lead to the accumulation of its biomass and bogginess, which will limit the use of sand quarry lakes for recreational and other types of nature management. Phytomeliorative tree planting around sand quarry lakes is proposed to regulate illumination as a parameter of the ecological niche of submerged plants.Документ Сучасні загрози та регулювання мікробіологічної безпеки харчових продуктів(Хмельницький національний університет, 2025) Матеюк, Олеся; Єфремова, Ольга; Міронова, Наталія; Matеyuk, Olesya; Yefremova, Olha; Mironova, NataliiaУ статті розглянуто актуальні проблеми мікробіологічної безпеки харчових продуктів в умовах глобалізації, зміни клімату та технологічного прогресу. Визначено основні групи мікробіологічних патогенів, фактори, що сприяють їх поширенню, та сучасні тенденції у регулюванні харчової безпеки на міжнародному та національному рівнях. Проаналізовано нормативно-правову базу регулювання критеріїв мікробіологічної безпеки харчових продуктів в Україні, включаючи норми щодо наявності умовно-патогенних та патогенних мікроорганізмів, збудників паразитарних захворювань та гранично допустимі концентрації мікотоксинів. Визначено необхідність вдосконалення систем контролю та регулювання для забезпечення безпеки харчових продуктів.
