The article discusses the best practices of hotel chains which consider ecological changes introduced into the technological processes of hotel enterprises, as well as the practices of eco-certification. The authors highlight some benefits, including economic ones, from the introduction of waste reduction and recycling programs in hotels. Green activities in the post-coronavirus period, due to growing demand for more environmentally friendly services, is seen as the one of primary importance. The article shares the analytical results of the Russian experience in hotel resource saving management. Waste disposal programs should be implemented in a comprehensive manner though environmental initiatives of hotel enterprises can be challenged by the absence of processing enterprises in the regions. It is concluded that green trends of accommodation facilities in the Russian and Kaliningrad hospitality sectors are not dynamic enough, which requires further enhancement of the regulatory and legal framework in the hospitality industry, including the introduction of eco-technologies.","PeriodicalId":345025,"journal":{"name":"Vestnik of Immanuel Kant Baltic Federal University Series Natural and Medical Sciences","volume":"191 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127592866","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attracting federal and extrabudgetary funds could be seen as an effective tool in the context of a local budget deficit. To date, improving the quality of urban spaces has been possible due to participation in the all-Russian competition for the best projects for creating a comfortable urban environment, which has been held since 2018. Having accumulated competencies in working on competitive project applications, and participating in numerous cross-border cooperation programs, Kaliningrad group actively and very effectively join in this competition, which has already changed the quality of the urban environment. Many small towns of the Kaliningrad region are on the list of federal leaders among the places with the most comfortable urban environment. This circumstance directly improves the possibilities of such cities in attracting investors, maintaining high-quality labor resources and the possibility of expanding their own regional socio-economic specialization.","PeriodicalId":345025,"journal":{"name":"Vestnik of Immanuel Kant Baltic Federal University Series Natural and Medical Sciences","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134552905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this article is to assess the degree of influence of agricultural development on the rural settlement process (the case of the southeastern part of the Kaliningrad region). The study examines the main economic and ekistical indicators of territory development including the indicators of the share of the rural population in the total regional population and individual districts and the indicators of the increase/decrease in the rural population.

It results in primary and secondary periodic dependence of the tendency to glass formation of substances of different nature. Presumably, the glass formation in alloys is promoted by structural-configurational equilibria, which are formed in vitrifying melts at the glass melting temperature between clusters of different degrees of polymerization, which are formed due to the fact that the electronic configurations of atoms in different chemically bonded states are close in terms of energy and correspond to both low — and high-molecular states of molecular groups in melts. The author proposes the parameters of glass formation, which are determined quantitatively, characterizing the ability of the atoms of the chemical elements that make up the melt to form a glassy network. The dependence of these parameters on the charge of the nucleus of the elements proves the primary and secondary periodicity of the tendency to glass formation in the case of sulfide, selenide, telluride, oxide and halide systems. The electronic configuration model turned out to be applicable to diamond-like and metallic systems. On the basis of the proposed theoretical concepts and data on the regions of glass formation of binary and ternary systems, a periodic system of glass formation of substances is proposed, i. e. the ability of simple substances and their alloys to form massive non-equilibrium non-crystalline objects.","PeriodicalId":345025,"journal":{"name":"Vestnik of Immanuel Kant Baltic Federal University Series Natural and Medical Sciences","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127949505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the study is to identify geographical features in the distribution of inbound tourist flows in the Benelux countries, using various approaches to data aggregation and visualization. The study is based on the national tourism statistics of the Benelux countries. Five leading countries in terms of the volume of inbound tourist flow in this region are considered: France, Germany, the United Kingdom, the Netherlands and Belgium. Four different indicators were used to analyze the distribution of inbound tourist flow: the total number of arrivals of foreign and domestic tourists in the region, inbound tourist flow diversity index, the share of arrivals from a particular country in the total volume of inbound tourist flow, and the degree of attendance calculated on the basis of the share of the country’s tourist the total tourist flow of the country. The regions that are the main centers of tourism (capital, seaside, border) and geographic factors that affect the degree of attendance of the region by tourists from different countries are identified: the language of the region, distance from the border, the capital factor and, in some cases, the presence of direct flights. The use of two different approaches to assessing the inbound tourist flow, carried out for the first time, made it possible to determine their advantages and disadvantages for further use.","PeriodicalId":345025,"journal":{"name":"Vestnik of Immanuel Kant Baltic Federal University Series Natural and Medical Sciences","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125495288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When assessing the existing and prospective healthcare infrastructure, it is advisable to take these points into account while developing an effective, evidence-based healthcare policy.
