ЗАКОНОДАВЧІ ТА НОРМАТИВНІ МЕТОДИ ОЦІНЮВАННЯ ЕКОЛОГІЇ В УКРАЇНІ

Sustainable development is quite popular scientific concept in a recent time, which formed the basis of the Ukrainian regional development strategic planning and regulation of urban development activities. However, the meth-odological basis for assessing the sustainability of the territorial development is still not developed and formalized enough. Methods for assessing the sustainability of territorial systems development in the economic, environmental and social spheres are still uncertain.Therefore, selected purpose of the study is an analysis of the existing methods of environmental assessment of the territorial development set forth in the legislative and regulatory documents, with further determination of the their suitability for conducting an assessment of the territorial development based on the sustainable development concept, which will form the scientific novelty of this study. To achieve this goal, the legislative and regulatory framework analysis was carried out in the field of territorial development, the main regulatory documents were identified. Subsequently, the definition of ecological assessment and its purpose for each of these basic documents was analyzed, environmental assessment methods and their application suitability for the environmental assessment of the territorial development based of the sustainable development concept were considered. It is concluded, that the environmental assessment methods proposed in these documents have numerous signifi-cant shortcomings when used for ecological assessment of the territorial development sustainability. There is no any formalized methodology for determining the sustainability of the relevant systems development in considered legisla-tive and regulatory documents. There is also an intersection of proposed environmental assessment methods with social and economic assessments. The optimality justifies of the adopted project decisions set issuing exclusively from the environmental and sanitary legislation requirements is incorrect in terms of sustainable development. The conclusion based on the obtained results was made about the need to improve the environmental assessment methods in their abil-ity of sustainable development concept implementation. The assessment of the current territorial state in the economic, social and environmental spheres must be carried out separately from each other while regional development strategies forms on the basis of sustainable development. It will pro-vide further assess of each sphere development balance and form a strategy direction for additional needed measures.Carrying environmental assessment, the strategy analysis for compliance with legislative and regulatory con-straints is insufficient in terms of the sustainable development concept. The assessment of environmental impacts should be carried out both for negative aspects and for positive, where the last are not normalized. Conclusions based on the negative environmental impacts absence are insufficient to consider strategies for developing such territories, as national parks or nature reserves. Therefore, the existing indicators system of environmental pollution levels by human activity as a basis for ecological assessment needs to be finalized, since it does not allow measuring the positive effects of some nature-recovery projects on the environment. Finally, it is necessary to formalize in legislative and regulatory documents the methods for the integrated sustainabil-ity assessment as a basis for consideration of alternative concepts for the territorial development. Formation and implementa-tion of appropriate methods can be selected as a direction for further research by the author on the chosen topic.Сталий розвиток є популярною останнім часом науковою концепцією, яку вітчизняними законодавчими актами закладено в основу стратегічного планування розвитку регіонів України та регулювання містобудівної діяльності. Але методологічна основа оцінки сталості розвитку територій досі розроблена та формалізована недостатньо. Майже не визначеними залишаються методи оцінки сталості розвитку територіальних систем в економічній, екологічній та соціальній сферах. Тому метою дослідження обрано аналіз відомих методів екологічної оцінки розвитку територій, викладених у законодавчих та нормативних документах, з подальшим визначенням придатності їх використання для проведення оцінки проектів розвитку територій на базі концепції сталого розвитку, що і становитиме наукову новизну цього дослідження. Для досягнення цієї мети було виконано аналіз законодавчої та нормативної бази в галузі територіально-го розвитку, виявлено основні регулюючі документи. Далі за кожним з цих основних документів було розглянуто наведене в ньому поняття екологічної оцінки та її призначення, визначені методи проведення екологічної оцінки, а також проаналізовано придатність до застосування викладених підходів та методик для здійснення екологічної оцінки розвитку територій на засадах концепції сталого розвитку. Отримано висновок, що запропоновані в розглянутих документах методи екологічної оцінки при їх використанні для екологічної оцінки сталості розвитку територій, матимуть численні суттєві недоліки. Жоден з розглянутих законодавчих та нормативних документів не наводить конкретної методики визначення сталості розвитку відповідної системи, в запропонованих методах екологічна оцінка пересікається із соціальною та економічною оцінками, наводяться некоректні з точки зору сталого розвитку обґрунтування оптимальності прийнятого комплексу проектних рішень виходячи виключно з вимог екологічного та санітарного законодавства. Отримані результати наводяться на висновок про необхідність вдосконалення методів екологічної оцінки в сфері розвитку територій з точки зору імплементації положень концепції сталого розвитку. При формуванні регіональних стратегій розвитку на засадах сталого розвитку, оцінка сучасного стану території в економічній, соціальній та екологічній сферах повинна здійснюватися окремо одна від одної для того, щоб мати можливість далі оцінити збалансованість розвитку за кожною сферою та сформувати відповідну стратегію у напрямі, який потребує додаткових заходів. При проведенні екологічної оцінки, аналіз стратегій лише на відповідність законодавчим та нормативним обмеженням є недостатнім з точки зору концепції сталого розвитку. Оцінка екологічних впливів повинна здійснюватися як для негативних аспектів, так і для позитивних, що не нормуються. Висновки щодо відсутності негативного впливу на довкілля є недостатніми для розгляду стратегій розвитку таких територій, як наприклад, національні парки або заповідники. Тому існуюча система показників рівнів забруднення довкілля діяльністю людини як основа екологічної оцінки потребує доопрацювання, адже не дає змоги виміряти позитивні впливи деяких природовідновлювальних проектів на довкілля. Нарешті, в законодавчих та нормативних документах потрібно формалізувати конкретні методи комплексної оцінки сталості розвитку як базу для розгляду альтернативних концепцій розвитку територій. Формування та впровадження відповідних методів і може бути обрано як напрямок подальших досліджень автора за обраною тематикою

Surfaces roughness effects on the transmission of Gaussian beams by anisotropic parallel plates

Influence of the plate surfaces roughness in precise ellipsometry experiments is studied. The realistic case of a Gaussian laser beam crossing a uniaxial platelet is considered. Expression for the transmittance is determined using the first order perturbation theory. In this frame, it is shown that interference takes place between the specular transmitted beam and the scattered field. This effect is due to the angular distribution of the Gaussian beam and is of first order in the roughness over wavelength ratio. As an application, a numerical simulation of the effects of quartz roughness surfaces at normal incidence is provided. The interference term is found to be strongly connected to the random nature of the surface roughness.Comment: 18 pages, Journal of Physics D: Applied Physics, volume 36, issue 21, pages 2697 - 270

Art technologies in the development of students’ emotional intelligence

The article presents an overview of domestic research devoted to the development of students’ emotional intelligence by means of art technologies. The relevance of the problem of developing emotional intelligence in modern students is determined by the objectives of higher education. Despite the serious experience gained in Russia in the use of art in teaching and personal education, the active penetration of art technologies into the education system began to occur relatively recently, which explains the time frame of the review study – 2019–2021. The analysis was performed in December 2021 using the national bibliographic database of scientific citation. The research was conducted using such combinations of keywords as “emotional intelligence”, “development of emotional intelligence of students”, “art therapy”, “pedagogical art therapy”, “art technology”, “art therapy at the university” in Russian for the period of 2019–2021. Out of 902 publications devoted to art therapy, the problem of using art technologies in higher education, the development of emotional intelligence through art technologies, the authors selected 49 publications. The analysis of the selected publications showed that the problem of the development of emotional intelligence arouses increased interest among researchers. However, the development of emotional intelligence in students is not a priority. In the system of professional education, the topic of emotional intelligence is not given enough attention, which is unacceptable and does not meet the requirements for the level of training of modern specialists. In recent studies, the possibilities of using art technologies in the development of students’ emotional intelligence have not been sufficiently disclosed. There is a need for further development of a program for the development of students’ emotional intelligence, presentation and description of art therapy techniques and techniques, their place and role in the development of emotional intelligence. Undoubtedly, building up the evidence base and substantiating methods for verifying the effectiveness of various art technologies will be a promising direction

Optimization of Agriculture Land Use Development Basing on Natural-resource Potential (On the Example of the Stavropol Territory)

Natural resources potential of the territory and natural-historical mechanism of its development are pacing factors in agriculture differentiation and AIC-development. Key branches in the Stavropol Territory are crop production, sheep breeding and meat and milk cattle breeding. To meet the market demands “equating” differentiation of agricultural enterprises is implemented. Thus, in Stavropol Territory crop lands have been increased for crops required in the market that disbalanced the crop rotation, disturbed agro technologies and resulted in reduction in yields and grain quality. In the Territory 70 % of tillage is in risky agriculture. About 65 % of crop production (wheat, barley and others) are in draughty areas where out of 141 years (1861–2002) 41 % draughty, which determine high natural-climatic dependence of grain economy [1]. Annual and areal variability of grain production is also determined by topsoil heterogeneity and variety of relief. At present production of the basic market crop – winter wheat, which takes 75 % of acreage for cereals and leguminous crops, the productivity of the cultivated crop is 22.4–39.5 centner/hectare. It results in top soil changes such as compaction, fertilizer impoverishment and organic matter content (organic matter deficit is 400–700 kg/ha). Intensification of agrarian production results in quicker erosion processes, soil properties decline and lower fertility. The total area of eroded lands in the Territory is 1792000 ha [2]. That is why it is important to develop a new model of the economic use of Stavropol Territory. The main methods of study are analysis of the current status and organization of the agricultural zones of the Territory. The data were preceded with the software Statistica

The impact of genetic polymorphisms in glutamate-cysteine ligase, a key enzyme of glutathione biosynthesis, on Ischemic stroke risk and brain infarct size

The purpose of this pilot study was to explore whether polymorphisms in genes encoding the catalytic (GCLC) and modifier (GCLM) subunits of glutamate-cysteine ligase, a rate-limiting enzyme in glutathione synthesis, play a role in the development of ischemic stroke (IS) and the extent of brain damag

Singlet exciton fission in solution.

Singlet exciton fission, the spin-conserving process that produces two triplet excited states from one photoexcited singlet state, is a means to circumvent the Shockley-Queisser limit in single-junction solar cells. Although the process through which singlet fission occurs is not well characterized, some local order is thought to be necessary for intermolecular coupling. Here, we report a triplet yield of 200% and triplet formation rates approaching the diffusion limit in solutions of bis(triisopropylsilylethynyl (TIPS)) pentacene. We observe a transient bound excimer intermediate, formed by the collision of one photoexcited and one ground-state TIPS-pentacene molecule. The intermediate breaks up when the two triplets separate to each TIPS-pentacene molecule. This efficient system is a model for future singlet-fission materials and for disordered device components that produce cascades of excited states from sunlight.B.J.W. was supported by a Herchel Smith Research Fellowship.

Genetic variation at the catalytic subunit of glutamate cysteine ligase contributes to the susceptibility to sporadic colorectal cancer: a pilot study

Glutathione is a tripeptide detoxifying a variety of exogenous and endogenous free radicals and carcinogens, and a deficiency of glutathione is associated with an increased host susceptibility to oxidative stress, a pathological condition implicated in the development and progression of cancer. The catalytic subunit of glutamate-cysteine ligase (GCLC) is an enzyme responsible for the initial and rate-limiting step of glutathione biosynthesi
