Currently, ecological management systems are an important prerequisite for successful functioning and competitiveness of accommodation facilities. 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.

Given the issue of balanced socio-economic development of the entire territory of the Kaliningrad region, an important task is to improve the quality of life in small towns in the region, as they serve as supporting elements for the regional settlement frame. 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.

Rural territories of the Kaliningrad Region are affected by polarization processes, which can characterize all regions of Russia. But at the same time, due to the small size of the region, they have their own features. In particular, they have a higher level of transport connectivity and a more developed infrastructure, compared with an average rural territory of Russia. 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. The author differentiates between the municipalities of the region according to specific weight of the rural population. In conclusion, the article defines the polarization processes occurring on the whole territory of the region and its south-eastern part and affecting the dynamics of the rural population settlement in the studied micro district.

The article proposes the periodic system of glass formation which is based on the model of glass formation where the possibility of forming glasses based on simple substances and similar alloys is associated with the features of the electronic configurations of atoms, such as stable electronic configurations s0, s2, p0, p3, p6, d0, d5, d10, f 0, f 7 and f 14. 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.

The tourism geography currently uses a variety of approaches to analyze tourist flows. 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.

The paper studies the data of a comprehensive environmental survey of land plots in several streets (i. e. Basseynaya, Lieutenant Katina and Sportivnaya) of the city of Kaliningrad for their compliance with the requirements for a specially protected natural area of local importance. It is shown that the territory of the indicated forest park zone meets the main criteria for designating a specially protected natural area of local importance. Given the urban environment, the territory has a high level of biological diversity, including regionally rare species; within the boundaries of the study area there are unique natural complexes and objects. This is a promising territory to carry out scientific research, environmental educational activities, ecological touristic activities, and regulated recreation.

Being in close proximity to the local community and its needs, a modern rural library in the Russian space is designed to be not only a center for users to access information, but also a place of education, cultural and intellectual activities, adaptation of residents to rapidly changing political, socio-economic, and psychological conditions. The rural library should act as an institution of socialization through developing a system of traditional values and preserving local culture, positioning itself as an open platform and involving residents in an active social and business life. In the article, the author considers the socio-economic development of the Slavsk municipal district based on the array of statistical and analytical data of the Slavsk library network, which is a valuable information resource. It is concluded that the library in rural areas is actively developing the principles of communication, education, memorialization, and information that are familiar to us, as well as newer ones — consolidation, education, adaptation, and the acquisition of integrity by the community.

The authors study the modern composition of the macrophyte flora of the Kaliningrad Bay (The Russian part of the Vistula Lagoon), which includes 116 species: 96 species of vascular plants and 20 species of macroalgae. Only 39 species of macrophytes were found in 2021, i. e., 19 species of higher plants and 20 species of macroalgae. Depending on the abiotic factors in the four hydrological regions of the lagoon, the floristic diversity and distribution of macrophytes has its own characteristics. The maximum species diversity (29 species), as well as the biomass of macrophytes, are characteristic of the eastern region, characterized by minimal salinity values and a high level of nutrients.

Apart from biomedical and organizational issues, the emergence of the new coronavirus COVID-19 (SARS-CoV-2) pandemic, set large-scale tasks for creating and improving mathematical and information technologies that operate spatial data in statistical analysis and forecasting. The regional level is seen as a suitable choice for spatial analysis of COVID-19 morbidity and mortality due to the availability of statistics, as well as data on geographical patterns, characteristics of the distribution space (population density, concentration in one city, density of the transport network, distance to the focus of the disease, etc.). The case of the Pskov region shows that the regional healthcare system experiences a significant shortage of personnel and a noticeable lack of resources. 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. The article shows that graph-based models are more likely to be efficient for adequate modeling at the interregional and regional level, while the geographical distribution of patients should be taken into account for the analysis of processes in individual settlements.

In recent decades, interest in halophyte plants has increased due to their high content of biologically active substances with powerful antioxidant, antimicrobial, anti-inflammatory and antitumor properties and promising for the prevention of various diseases. Several species of halophytes grow on the territory of the Kaliningrad region, among which the rare species Spergularia marina (L.) Griseb. is of particular interest, the biological activity and content of secondary metabolites of which have not been studied sufficiently. The purpose of this study was to obtain callus cultures, to study the content of some groups of phenolic compounds and the antioxidant activity of extracts. The study carried out the selection of growth regulators and concentrations that induce callus formation. 19 nutrient media were selected for the induction of S. marina callus cultures. The conducted phytochemical analysis showed a significant content of phenolic compounds and hydroxycinnamic acids, as well as a high level of antioxidant activity of extracts of callus cultures. Out of 19 callus cultures, cultures obtained on Murashige and Skoog nutrient media containing the following combinations of growth regulators are promising for obtaining target secondary metabolites: 0.25 mg/l TDZ and 1 mg/l 2,4-D; 0.1 mg/l TDZ and 1.5 mg/l 2,4-D; 0.25 mg/l TDZ and 0.25 mg/l IBA; 0.5 mg/l TDZ and 0.25 mg/l IBA; 0.25 mg/l KinN and 0.5 mg/l 2,4-D.
