The analysis of the biotic component in determining of the quality of surface water is becoming increasingly important. The aim of the work was to assess the ecological quality of the river ecosystems from the influence of wastewater discharges of the Grodno, Stolbtsy and Vileyka cities on the Neman and Viliya rivers based on the macrozoobenthos community.The rare and protected species of hydrobionts from number of European countries live in the studied rivers. Among them are mollusks, coleoptera, caddis flies, and crustaceans. The stoneflies – highest priority indicator group of hydrobionts is missing in the Neman river. Mayflies and caddis flies are also poorly represented (2nd and 3rd indicator groups). The all three main indicator groups of aquatic organisms are presented in the Viliya river. The biotic indices are determined and the class of water purity of the studied rivers was calculated. In accordance with the EU Water Framework Directive, the cleanliness class has good and high value. It is concluded that the negative impact of wastewater from the cities of Grodno, Stolbtsy and Vileyka is of very local importance and weakly affects the biota and ecological quality of the water of the Neman and Viliya rivers.

In determining the quality of surface waters and, first of all, rivers, along with physical and chemical pollution, the analysis of the hydrobiological component of river ecosystems is becoming increasingly important. The aim of the work was to assess the ecological quality of the river ecosystems from the impact of wastewater discharge from the cities of Vitebsk, Polotsk and Novopolotsk on the Western Dvina River based on the macrozoobenthos community. The studied river sections are inhabited by rare for Belarus and protected in Europe species of aquatic organisms. A relatively high abundance (from 30 to 80 %) of the group of rheophilic species Plecoptera, Ephemeroptera, and Trichoptera was noted, which represent the three highest priority indicator groups of aquatic organisms. Biotic indices and the water purity class of the r. Western Dvina were determined. In accordance with the EU Water Framework Directive, the water purity class at the studied stations has a good and high value. It is concluded that the negative impact of wastewater from the cities of Vitebsk, Polotsk and Novopolotsk has a very local significance and weakly affects the biota and the ecological quality of the water of the Western Dvina River already at a distance of 18 km. below the discharge of water from the treatment facilities of the Novopolotsk refinery.

Recently, with the rapid increase of urban population and industrial agglomeration, the price of construction land has increased, and construction land has become increasingly scarce. Therefore, how to improve the construction land use quality (CLUQ) becomes more and more important. The purpose of the study is to evaluate CLUQ in China’s major cities and to analyze the dominant obstacle factors for quality improvement in order to provide policy advice for construction land management. This study adapts the data from 2014 to 2016 and constructs the evaluation framework of CLUQ involving economic quality, social quality, and ecological quality of construction land to evaluate and analyze CLUQ with the synthetic evaluation model, coupling evaluation model, and obstacle diagnosis model (ECO model). This study shows that the synthetic CLUQ of 23 cities out of 36 major cities in China shows a general increasing state. The economic quality of 26 cities out of 36 major cities in China has increased, while the social and ecological quality of 20 out of 36 major cities in China has decreased. In terms of spatial characteristics, the synthetic quality in the east and southwest of China is relatively high; in terms of spatial trend, the synthetic quality in longitude increases from west to east, and it shows an inverted U-shaped state in latitude. Moreover, economic development is the main obstacle factor for the improvement of CLUQ in Hohhot, Lanzhou, Urumqi, and Changchun. Social development results in the CLUQ lagging in Beijing, Guiyang, Shanghai, Xining, and Chongqing. Ecological development has a negative impact in that of Harbin, Qingdao, and Wuhan. Furthermore. The improvement of CLUQ lies in the coupling and coordinated development of economic, social, and ecological quality. For those with a low coupling degree, the targeted suggestions are given for different types based on city’s quadrant distribution.

Abstract This research has the aim of establishing the amount of land that the Conservation Area National System (SINAC) needs to buy and specifying its use inside the Golfo Dulce Forest Reserve in order to maintain the good quality of the rivers. The study was done inside Rincon sub-basin in the Osa Peninsula, a land dedicated to primary and secondary forest (Melina tree plantations), mangrove forest, urbanism, chaparral, pasture for grazing livestock and crop cultivation, mainly rice and African palm; uses that may change in time affecting the actual water quality (WQ) in rivers and the bay. Changes in land uses modify the WQ and it can be predicted using WQ models based on environmental variables through the evaluation of different scenarios. It was found through modeling that pasture or chaparral land use has no negative impact on WQ; all the contrary happens with increments in crop cultivation or human population. At the present, the coastal area, adjacent to the reserve, has low agricultural activity but that could increase over time, affecting the WQ. Therefore, SINAC should continue with its acquisition land activity to counteract the negative environmental effect of agricultural activity to preserve the actual good quality of the rivers.

The impact of the last global economic crisis (2008) on the European economy put a strain on higher education (HE), yet it also pushed the sector towards intensive reforms and improvements. This paper focuses on the “Strategy for the Development of Higher Education in the Republic of Bulgaria 2014-2020”. With a case study methodology, we explore the strategic endeavours of the Bulgarian government to comply with the European directions and to secure sustainable growth for the HE sector. Our research question is ‘How capable is the Bulgarian HE Strategy to overcome the economic and systemic restraints of Bulgarian higher education?’. Because the development of strategies for HE within the EU is highly contextual, a single qualitative case study was chosen as the research approach. HE institutions are not ivory towers, but subjects to a variety of external and internal forces. Within the EU, this is obviated by the fact that Universities obtain their funds from institutions such as governments, students and their families, donors, as well as EU-level programmes. Therefore, to explore how these pressures interact to affect strategic action on national level, the case method is well suited as it enabled us to study the phenomena thoroughly and deeply. The paper suggests the actions proposed within the Strategy have the potential to overcome the delay, the regional isolation and the negative impact of the economic crisis on the country. Nevertheless, the key elements on which the success or failure of this Strategy hinges are the control mechanisms and the approach to implementation. Shortcomings in these two aspects of strategic actions in HE seem to mark the difference between gaining long-term benefits and merely saving face in front of international institutions.

This article is devoted to the study of the image of Executive authorities in modern Russia. The relevance of the chosen topic of the scientific article is emphasized for the present time, when society and the state are developing methods of countering the coronavirus pandemic – not only in the medical, but, no less important, in the socio-psychological aspect. In this perspective, the consolidating potential of a positive image of government bodies and civil servants is noted. Attention is focused on the terminological apparatus of the problem. Based on the analysis of relevant scientific works, the article provides the author's definition of the image of public authorities. The author notes the peculiarity of the image of Executive authorities, which consists in the presence of two inextricably linked equivalent components – the image of the authority and the image of a civil servant. Image formation of government bodies is considered as a multi-factor interaction of three main subjects: government bodies, the population, and the mass media. The main method of implementation is still the mass communication media, which provide a permanent presence of Executive authorities in the information and communication space. It is noted that the basis for the formation of a positive image of the Executive authority and bureaucracy is their effective functioning. At the same time, the perception of citizens, their attitude to the activities of Executive authorities, the level of trust in them is considered as the main indicator of the modality of the image. Based on the analysis of data from sociological studies, the conclusion about a positive trend in the perception of public authorities and officials by Russians is substantiated. However, there is a negative impact on their image of the lack of these changes and, in General, a low level of openness of public authorities.

Political security is very often considered through the prism of individual states. In the scholar literature in-depth analyses of this kind of security are rarely encountered in the context of international entities that these countries integrate. The purpose of this article is to draw attention to key aspects of political security in the European Union (EU) Member States. The EU as a supranational organisation, gathering Member States first, ensures the stability of the EU as a whole, and secondly, it ensures that Member States respect common values and principles. Additionally, the EU institutions focus on ensuring the proper functioning of the Eurozone (also called officially “euro area” in EU regulations). Actions that may have a negative impact on the level of the EU’s political security include the boycott of establishing new institutions conducive to the peaceful coexistence and development of states. These threats seem to have a significant impact on the situation in the EU in the face of the proposed (and not accepted by Member States not belonging to the Eurogroup) Eurozone reforms concerning, inter alia, appointment of the Minister of Economy and Finance and the creation of a new institution - the European Monetary Fund.

The author proves that the successful stability of independent Slovenia contributed to a number of factors, existing since its being incorporated in the SFRY. The factor, uniting the state has become the common goal – the aspiration to join the EU. The process of the European integration contributed to the modernization of a number of spheres, in particular social, cultural and economic ones. The global financial and economic crisis has revealed the turmoil in the economy of the state and its leadership was forced to gradually reduce a significant part of social privileges for the population. This caused the tension in the society and reduced the level of the national unity, having a negative impact on people’s wellbeing. However, since 2014, the Prime Minister M. Cherar has been trying to restore people’s trust in the state. The situation is getting better; indicators of trust in government are increasing, which also points to state capacity and political regime stability in Slovenia.

Инфекции мочевых путей - наиболее распространённая группа заболеваний в практике врача уролога. Один из представителей является хронический рецидивирующий бактериальный цистит. Данное заболевание встречается во всех возрастных категориях и затрагивает все сферы жизни пациентов. Симптомы, возникающие при обострении хронического бактериального цистита, оказывают негативное влияние на качество жизни, что может приводить к нарушению психоэмоционального состояния больных. Отдельную группу высокого риска в отношении ИНМП составляют пациенты с нарушением углеводного обмена, у которых риск развития различных инфекций выше, чем у людей без подобных нарушений. К факторам, повышающим риск развития ИНМП у больных с нарушением углеводного обмена, относят возраст, компенсацию и наличие хронических осложнений, в первую очередь нефропатии и цистопатии. Человеческий организм функционирует циклически в соответствии с определенными индивидуальными ритмами. Любое хроническое заболевание приводит к рассогласованию процессов, протекающих в различных системах организма, вызывая развитие десинхроноза. Наличие у человека более 1 хронического заболевания утяжеляет течение болезни и приводит к снижению восстановительных способностей организма и сокращению его адаптационного потенциала Urinary tract Infections are the most common group of diseases in the practice of a urologist. One of the representatives is chronic recurrent bacterial cystitis. This disease occurs in all age categories and affects all areas of life of patients. Symptoms that occur with the exacerbation of chronic bacterial cystitis have a negative impact on the quality of life, which can lead to a violation of the psychoemotional state of patients. A separate high-risk group for INMP is patients with impaired carbohydrate metabolism, who have a higher risk of developing various infections than people without such disorders. Factors that increase the risk of developing INMP in patients with impaired carbohydrate metabolism include age, compensation, and the presence of chronic complications, primarily nephropathy and cystopathy. The human body functions cyclically in accordance with certain individual rhythms. Any chronic disease leads to misalignment of the processes occurring in various body systems, causing the development of DS, the Presence of more than 1 chronic disease complicates the course of disease and leads to a decrease in regenerative abilities of the organism and reduce its adaptive capacity
