SPORT MANAGEMENT PROBLEMS IN POST INDUSTRIAL REGIONS ON EXAMPLE OF CITIES IN SILESIA PROVINCE
Contemporary sport is a social and economic phenomenon. These two areas require special analysis in the process of managing the development of sport by city administrations. The restructuring of the region's economy and the closure of heavy industry companies are changing the methods of financing sports. The main aim of the article is to indicate the key problems of sport management by the city governments in the time of socio-economic changes in Poland for last years, on the example of the one of the most industrialized regions in Europe – Silesia province. To achieve this aim, the methods of analyzing the literature of the subject, reports on sport market and strategic documents of selected city administrations were used. The study focuses on cities where for many years sport was financed from the budgets of the largest companies (heavy industry companies). The author is aware of the limitations associated with this research and inference resulting from a small research sample and the dynamics of changes in the economy but the process of economic changes in the region is still strongly influencing on sport market. The involvement of public funds both from the city and the central administration seems necessary. Especially with regard to the maintenance of the existing sports infrastructure. Money for sports clubs requires clear access criteria and transparency in decision-making processes. It is important to strategically plan the development of sport. The development ought to be understood not only as a numerical / quantitative growth, but also a qualitative one. The described and analyzed factors influencing the development of the sport market, including in particular the management dilemmas during economic changes in Europe, can be used by local governments to effectively support sport development market. The article has been based on analyzing many former and still existing strategic documents which are referring to sport management in the region. Author and also has referred to the concept of the development of the sport market in the time of industrial changes in Silesia province.
INVESTIGATION OF THE LUSITANIAN SLUG (ARION LUSITANICUS MABILLE) DAMAGE
The Lusitanian slugs (Arion lusitanicus Mabille) is one of the species of invasive animals originated from Spain and Portugal, Lusitania region in particular. The slugs were first detected in 2008 in Kaunas, Lithuania. The spread of this species is rapidly increasing, which creates unfavourable conditions for growing plants in gardens, orchards, and other areas. The study was carried out in the orchard of Vytautas Magnus University Botanical Garden by controlling their damage by applying mulch of buckwheat husks. The aim of the research was to identify the effectiveness of buckwheat husks as a natural plant waste in protecting garden plants from damage caused by the Lusitanian slugs. In 2021, the study was carried out in the training garden, the collection department of VMU Botanical Garden. The benefits of mulching lettuce with buckwheat husks to protect them from invasive slug damage have been analysed. The lettuce examined were grown in 1.2 m width beds, where the gaps between vegetable beds were surrounded by a well-maintained lawn. There were four replicates of the study, when the area of 1 m2 was investigated. At the investigated sites, plants were mulched with a dry, loose, and clean buckwheat husk layer of 5 cm thickness. The damage caused by the Lusitanian slugs was recorded by measuring damage on plant leaves and converting the damage into the percentage expression. The phytofixation method was used. Damage was assessed on a five-point scale, where 0 points - plants undamaged, 1 point - damaged up to 15%, 2 points - damaged from 15 to 30 per cent 3 points - damaged from 30 to 50 per cent, 4 points - damaged from 50 to 75 per cent, 5 points - damaged (destroyed) from 75 to 100 per cent of leaves of the investigated plants. The results of the research showed that the use of special partitions made from buckwheat husks and mulching of vegetables can control the damage of invasive slugs. Minor damage was found in vegetables mulched with buckwheat husks: damage from 1 to 2 points. In the control site, where the plants were not mulched with buckwheat husks, the damage was 3 points. Having assessed the damage, it can be stated that the activity of Lusitanian slugs was affected by less favourable environmental conditions: sunny days, high ambient air temperature, limited level of precipitation and a wellmaintained environment, as there were no shady places and high grasslands or other common shelters for slugs.
CIRCULAR ECONOMY – THE OVERVIEW OF GOOD PRACTICE IN EUROPE
The concept of a circular economy is a challenge, but at the same time a great opportunity for economic and social development. Actions taken at the national level are necessary due to the depletion of natural resources, and more importantly, changes in the environment that have a negative impact on human life and health. New business models, corresponding to the assumptions of the circular economy concept, result in the creation of new opportunities for enterprises. It is important to promote experiences and good practices in the development of the circular economy at the national level. The aim of the article is to review good practices and experiences of selected countries in the field of circular economy, along with an indication of available sources of funding. The desk research is part of the implementation of Intellectual Output 1 and 2 of the EnMind Erasmus+ Cooperation for innovation and the exchange of good practices project. The project consists in the development of a Toolkit addressed to youth workers that will allow them to support and help young people who want to start a social entrepreneurship. The presented good practices have been selected from the circular economy database in practice, and the presented case studies represent entities with a uniform scale and scope of activity.
FREQUENCY OF MICROSCOPIC FUNGI IN THE UPPER LAYER SOIL OF CONIFEROUS TREE STANDS
The present study was designed to examine the frequency and prevalence of microscopic fungi in the top layer of mineral soil of native Pinus sylvestris L., Picea abies (L.) H. Karst. and alien Thuja occidentalis L. and Larix sibirica Lebed tree stands. Studies on fungi frequency were conducted in January, March, May, July, August and November of 2020, the prevalence of fungi genera – in March of 2021. Biochemical composition (N, Corg, Ca, lignin) of investigated tree litter was also rated. By the carbon and nitrogen (C:N) and lignin and nitrogen (Lig:N) ratios, the slowest decompositions were of the T. occidentalis litter and the fastest one – of P. abies litter. Most abundant microscopic fungi were found in early spring (March) and late autumn (November) and the least one – at the end of summer (August). The biggest average frequency of microscopic fungi was in the soil of T. occidentalis and the least one – in P. sylvestris stands. The higher lignin content and Lig:N ratio in litter positively influenced the number of microscopic fungi in upper layer of mineral soil. The largest part (80 – 39%) of fungi in all investigated stands soil consisted of Penicillium Link, Geomyces Traaen and Mucor P. Micheli ex L. genera. The composition of fungi genus differed most from other stands in T. occidentalis soil. The greatest diversity of fungal genera was found in P. sylvestris stand soil.
IMPACT OF E-TECHNOLOGY ON DESTINATION BRAND AWARENESS
Brand awareness is the strength of the brand’s presence in the mind of the target audience and is an integral part of the ConsumerBased Brand Equity (CBBE) model. In combination with the Brand Image, Quality, and Loyalty, Brand Awareness contributes to the overall destination competitiveness. For addressing the intent, from the Travel & Tourism Competitiveness Index (TTCI) of the World Economic Forum are selected pillars that evaluate online and digital performance of the destination and is assessed their relationship with the destination brand awareness. According to the conducted analysis is determined that e-technology, such as “Internet use for business-to-consumer transactions” is the major pillar from applicable TTCI sub-indexes which establishes destination brand awareness; therefore improving performance of this sub-index will have positive effect on the performance of the brand awareness. It has been also determined that Georgia as a tourism destination performs significantly poorly in this pillar compared to direct regional competitors. In addition, findings indicate that Croatia is the strongest performer in the region and therefore is appropriate for Georgian tourism stakeholders to closer assess models and systems used by the Croatian tourism sector.

CONSUMER CHOICE FOR LOCAL FOOD: EXAMPLE OF LATVIA AND LITHUANIA
Currently, there are two opposing processes in the market development. On one hand, globalisation brings new choices; border is not a barrier anymore to obtain a desired good or service. On the other hand, the society increasingly starts to recognize the importance of sustainable development and, consequently, importance of the process opposite to the globalisation – localisation. This is particularly the case in the food industry, where people start to pay more attention to the origin of products. The purpose of this article is to explore the consumers’ choice of the local products on the example of Latvia and Lithuania. In 2017, the authors conducted a survey in Latvia discovering that the origin of food is important to the people, and the local food increasingly becomes important for the consumers. Similar pilot study has been launched in Lithuania to compare the attitudes and preferences of the citizens of two neighbouring countries in favour of the locally produced food. The survey method, logical-constructive method, monographic and graphical methods are used in this research. As a result, it has been concluded that similar tendencies are observed in the two geographical areas of study – the consumers prefer the products of the local domestic producers. However, there are also some discrepancies, mainly due to the different levels of territorial development.

In regard with the physical and chemical properties of heat-accumulating materials, commonly used in SAHS, the capacity of heat accumulator is used to cover the thermal loss of a building at night. On the basis of the data obtained, the solar air heating system (SAHS) with an air solar collector and a thermal battery has been developed.
The development of the meetings industry is related to development of business tourism to cities. There is an increasing number of meeting venues and multifunctional arenas along with events and visitors. It is related to the growth of global and economic, political, socio-cultural changes and new technologies. The benefits of the meetings industry are result from the attractiveness of business tourism as a city product and a form of city promotion. The changes taking place in the meetings market encourage local government of cities, that are not capitals (so called "second tier cities”), to more actively apply for the organisation of large international events. The city administration that wants to develop business tourism in their area, has to take into account many conditions in their destination (city) management. The key external and internal factors affecting the development of business tourism second tier cities have been identified in the article. The methods of literature analysis of the subject, passive observation of events and data from previous publications have been applied for the research.
ISOLATION OF CHITIN-GLUCAN COMPLEX FROM ASPERGILLUS NIGER BIOMASS, A BY-PRODUCT OF CITRIC ACID PRODUCTION
The excretion of radionuclides, toxic substances, pathogenic microorganisms from the human body contributes to the preservation of health and the duration of life. In the world, there are various natural biopolymers, in particular, biopolymer of the 21st century, chitin and its derivatives, which have a significant effect on the body. The daily recommended intake of chitin ranges from 3 to 7 g. In the food industry, chitosan (a chitin derivative) is used as a stabilizer, preservative, clarifier, emulsifier, and structurant. In medicine, based on chitosan, apyrogenic surgical threads and sutures are made. The sorption ability of chitin is used to purify water and localize leaks of radioactive substances. Scientific developments are under way to improve the technologies for the isolation of chitin and its derivatives from chitin-containing raw materials of various origins as well as expand the scope of application of these biopolymers. On the production scale of the Republic of Belarus, the isolation of the chitin-glucan complex from a by-product of citric acid production does not require significant raw material costs, and at the same time solves the problems associated with the processing of the by-product. The extraction of the chitin-glucan complex was carried out according to two developed technologies: having pretreated chitin-containing raw material with a solution of hydrochloric acid and an ozone-air mixture. The organoleptic evaluation and physicochemical analysis of the samples were carried out as well as the comparative evaluation with imported samples of chitosan. It has been established that the chitin-glucan complex has some advantages in terms of flavor characteristics as compared to imported analogues: anonymized odor and neutral taste, which makes it possible to use it not only as an independent food product, but also as a functional ingredient in other foods that do not alter taste of the main product. For the first time in the Republic of Belarus, a study of the morphological structure, chemical composition and X-ray diffraction analysis of the chitin-glucan complex were conducted. It has been established that the chitin-glucan complex has a porous structure and an amorphous-crystalline structure.
FACTORS AFFECTING THE EFFICIENCY OF WORK OF THE HORIZONTAL EARTH-AIR HEAT EXCHANGER IN GEOTHERMAL VENTILATION SYSTEM
To save energy in mechanical ventilation systems, it is advisable to use earth-air heat exchangers. They are intended for the transfer of low-potential soil heat to the air entering the ventilation system. The efficiency of heat exchange between soil and air depends on many factors. Moreover, some factors significantly affect the heat transfer process, and some can be neglected. This article identifies all factors that affect the performance of a horizontal earthair heat exchanger. It is determined which factors depend on the location of soil heat exchangers, and, accordingly, are permanent for the concret the terrain. There are factors that can vary depending on the task of designing the object. The basic parameters are determined, the change of which will allow to increase the heat exchange between soil and air in the heat exchanger, in particular, the speed of air movement and the diameter of the pipe of the heat exchanger. In addition, the intensification of heat transfer is carried out by the turbulence of air flow in the soil heat exchanger.
DETERMINATION OF BODY COMPOSITION BY BIO-IMPEDANCE ANALYSIS IN YOUNG STUDENTS
Using experimental data for adults (a total number of adults examined -236 out of which 74 male and 162 female students at Yanka Kupala State University of Grodno, Belarus) comparisons between the fatty mass body determined by a bio-impedance analysis method, and the body mass index (Quetelet's index) calculated on the basis of anthropometrical measurements have been carried out. A statistical calculation of the experimental data has been applied. At a stage of the specification pair exponential regression has been selected. Its parameters were estimated by method of the least squares. The statistical importance of the equation was verified using the determination coefficient and Fischer’s criterion. The correlation coefficient based on the experimental data between the fatty mass body and Quetelet's index is b =0.042. The analysis showed that deviations when calculating the same object using the coefficients as provided in literature can reach 30%. For group of male students the parameters determined by anthropometrical and electric characteristics of the person have been analysed. The analysis revealed that relative fatty mass characterizes norm of a body state more precisely in comparison to the body mass index.
ECONOMIC MISSIONS AS AN INSTRUMENT TO SUPPORT BUSINESS TOURISM OF ENTERPRISES IN 2014-2020

Lietuvos Respublikos Seimas ir Vyriausybė, įgyvendindami Europos Parlamento ir Tarybos direktyvos 2013/34/ES nuostatas, priėmė atitinkamus pakeitimus įstatymuose ir norminiuose aktuose. Šių pakeitimų rezultatas – nuo 2016 metų pradžios Lietuvos Respublikoje veikiančios verslo įmonės, vedančios savo apskaitą pagal Verslo apskaitos standartus (VAS), privalo sudaryti ir teikti metinę finansinę atskaitomybę naujos formos finansinėse ataskaitose. Vienas populiariausių verslo įmonių finansų valdyme naudojamų būdų yra finansinė analizė, kurios atlikimas dažniausiai pradedamas nuo informacijos finansinėse ataskaitose analizės. Todėl galima teigti, kad finansinių ataskaitų formų, kaip pradinio informacinio šaltinio verslo įmonių finansinei analizei, pakeitimas gali turėti įtaką tiek analizės, tiek verslo valdymo rezultatams. Straipsnyje tiriami pokyčiai verslo įmonių finansinių ataskaitų sudėtyje, nagrinėjami nauji finansinių ataskaitų rinkiniai, atskleidžiami šių rinkinių analizės ypatumai bei jų įtaka finansinės analizės atlikimui ir rezultatams. Apibendrindamas praktinę analitinę veiklą, autorius pateikia siūlymus, kaip sistemiškai spręsti įmonių finansinės analizės informacinio aprūpinimo klausimus, dirbant su naujos formos finansinėmis ataskaitomis.

AUTOTRANSPORTO KELIAMO TRIUKŠMO KAUNO KOLEGIJOS TERITORIJOJE SKLAIDOS MODELIAVIMAS IR ANALIZĖ
Gerėjant ekonomikai vis daugiau šeimos ūkių gali sau leisti įsigyti automobilį ar netgi kelis. Didėjant automobilių skaičiui, kartu didėja ir jų keliamo triukšmo lygis. Atlikus daugybę mokslinių studijų nustatyta, jog autotransporto keliamas triukšmas yra pavojingas žmonių sveikatai. Pagal galiojančias normas triukšmas gyvenamųjų teritorijų zonoje dienos metu neturi viršyti 65 dBA. Kauno kolegijos miestelis įsikūręs prie vienos judriausių miesto gatvių – Pramonės prospekto. Čia fiksuojami didžiuliai transporto srautai. Tyrimas atliktas 2016 metų balandžio mėnesį. Buvo fiksuotas pro Kolegijos miestelį pravažiuojančių transporto priemonių skaičius. Su ArcGIS programinės įrangos moduliu MapNoise, naudojant statistines funkcijas IDW, Spline ir Kriging, atlikta transporto keliamo triukšmo analizė. Jos rezultatai parodė, kad iš Pramonės pr. pusės pagal dienos lygio vidurkius triukšmo lygis svyruoja tarp 55 - 65 dBA. Nustatyta, jog triukšmą reikšmingai mažina šalia Kolegijos augantys medžiai ir krūmai, nes be jų triukšmo lygis padidėtų dar apie 5 dBA.
