ABSTRACT. The paper deals with the problem of future biology teachers' vocational preparation process and shaping in them of those capacities that contribute to the conservation and enhancement of our planet's biodiversity as a reflection of the leading sustainable development goals of society. Such personality traits are viewed through the prism of forming the future biology teachers' professional and terminological competence. Professional and terminological competence has been defined as the formed ability of specialists to competently and expediently use vocational terms in their professional activity. The main aspects and categories that characterize the professional and terminological competence of future biology teachers, including terminology, nomenclature, term, nomen and term element, have been explained. The criteria and stages of shaping the future biology teachers' professional and terminological competence during the vocational training process have been fixed. Methodical support for shaping students' professional and terminological competence has been substantiated. Methods, techniques, technologies, guiding principles and forms of staged work on the forming of an active terminological dictionary of future biology teachers have been described and specified. The content of the distant special course "Latin. Botanical Terminology" which provides training for future teachers, based on knowledge of Latin, to perceive the professional subjects and to understand of international scientific terminology, has been presented. It is concluded that the proper level of formation of the future biology teachers' professional and terminological competence will eventually ensure the qualitative preparation of students for life in a sustainable development era.

ABSTRACT. Research goals: the idea of the study is that the value potential of the subject is a fundamental element of the knowledge system as part of the realization of the idea of sustainable development in education. The purpose of the study is to study the state of the issue of the formation of value ideas in students by means of the subject “Biology”. The basis of the study used the classification of value categories proposed by Milton Rokeach (1979). Object of research: value ideas of students. Subject of research: factors in the formation of value representations of students by means of the subject "Biology". Research methods: analysis of scientific publications on the methodology for assessing the value ideas of the individual, qualitative and quantitative methods of psychological and pedagogical research. Results of the research: we gave definitions to the concepts of “value potential of a subject” and “value potential of basic science”. We found that in the main school, the content of the subject “Biology” is primarily aimed at forming ideas about terminal values - “life”, “health”, “nature”; in high school - about terminal values - “life”, “health”, as well as instrumental values - “perseverance”. The value ideas of a biology teacher are one of the key factors in the formation of students' value ideas. In the structure of value representations of biology teachers, the three leaders are orientations towards terminal values. We have put forward the assumption that there is a dissonance between the value ideas of respondents and the values that the school biology course is aimed at forming an idea about.

ABSTRACT. Aspects of learning styles modelled on R. Felder and B. Soloman are discussed in detail. The results of the study of the educational advantages of students of KryvyiRih State Pedagogical University of the speciality "014 Secondary education (Chemistry)" are presented. It is shown that the majority of students in the group are those who study visually, sensitively, actively and consistently. According to studied features of the student's groups didactic material on the theme "Ecological Chemistry of the Lithosphere" of the content module "Ecological Chemistry of Environmental Objects" was elaborated and its role and place in the structure of the educational process determined. Forms of work that involve the use of different cognitive functions are described and therefore contribute to their balanced development. It allows a person to be flexible in the unrestrained development of technological progress, to be open to different ways of obtaining information and perceiving it without resistance and stress.

ABSTRACT. The studies were performed at the Petrovsky waste rock dump, Central part of the Kryvyi Rih iron district (Dnipropetrovsk region, Ukraine). The macronutrients (K, Ca, Mg, P, S) and heavy metals (Fe, Mn, Zn, Cu, Pb, Cd) content in the leaves of the three tree species (Ash-leaved maple, Silver Birch. and Black locust.) that were collected on devastated lands was studied. It is established that the growth and development of trees on the Petrovsky dump is carried out with a clear shortage of nutrients (especially K and P) and an excess of metals (especially Fe, Mn and Zn). It is revealed that Ash-leaved maple and Black locust are more resistant to the geochemical conditions of devastated lands. In this regard, these species of trees can be recommended for the creation of artificial tree plantations on devastated

ABSTRACT. Sorption-colorimetric and naked eye determination of germanium as ion associates of GeMo12O40 4- with triphenylmethane dyes. The sorption of the ionic associates (IA) of 12-molybdogermanat with astrafloxin (AF) on filter paper was studied. The colored scales for naked eye detection and dependence of chromaticity coordinates from the germanium (IV) concentration were obtained. The methods were applied to the determination of germanium (IV) in coked coal, iron ore, and in waters in the concentration range from 4• 10-8 to 1• 10-6 mol•l-1.

ABSTRACT. The critical analysis of known technologies for soil restoration, contaminated by heavy metals and radionuclides remains relevant Object of work: to systematize (taking into account the possible consequences to biosphere) the known technologies for ecological restoration of soils contaminated by heavy metals and radionuclides one possible methodology for solving any soil problem should be recognized only as a healing technology. For soils contaminated by heavy metals and radionuclides healing patterns is ordered conceptually into the following levels: mission, strategy, technology. The mission of healthy soil should be aimed at maintaining the chemical elements content within the optimum interval. The strategy of healthy soil involves the regulation of individual elements content in the soil. Ex-situ a soil healing technologies is implemented outside the original pollution site. In-situ, a soil healing technologies is carried out directly on the original pollution site. Excavation of the contaminated soil layer is the first stage for ex-situ soil restoration. In the future it will be possible: 1) storage of contaminated soil at special landfills, 2) treatment of contaminated soil at a special reactor. All technologies for in-situ healthy of heavy metals contaminated soils can be ordered as: 1) localization, 2) deconcentration, 3) inactivation, 4) extraction.

ABSTRACT. Environmental monitoring was conducted of facilities for storage and disposal of banned and unsuitable pesticides. Pesticide content in the soil, water, and products of agriculture in the Zhytomyr region of Ukraine was examined, and the accumulation of organochlorine pesticides by freshwater bivalve mollusks was assessed. Storage facilities of the Zhytomyr region contain nearly 392.18 t of pesticides in 137 warehouses, of which 11 meet the requirements, 36 are tolerable, and 94 are in poor condition. In 2018−2019, pesticide content (dichlorodiphenyltrichloroethane (DDT), heptachlor, dichlorodiphenyldichloroethylene (DDE), dichlorodiphenyldichloroethane (DDD), hexachlorocyclohexane (HCH)) was studied in soil and sediments in the Zhytomyr region. The content ranged from 0.0007 to 0.07 mg/kg, which is lower than MPC (0.1 mg/kg). The content of HCH, DDT, DDE, DDD, and heptachlor was at 0.0007−0.01 mg/dm3 levels in water bodies of the Zhytomyr region in 2018–2019, also lower than MPC. In some samples of soil, water and vegetables, the recorded levels of DDT and organophosphate pesticides Dragon, Dorpan, and Dursban exceeded MPC in 1.5–3.0 times. Traces of organochlorine pesticide Aldrin were found in soft tissues of bivalve mollusks and in the sediments of water bodies they inhabit. Recommendations are proposed to lower the pesticide content in the environment.

ABSTRACT. The article is focused on the successful implementation of the global goals of restoring water objects in the context of sustainable development that is impossible without solving the regional problems of local watercourses and reservoirs reviving. It is emphasized that awareness of riparian spaces role as ecological corridors and importance of the healthy functioning of the river network through the revitalisation of even minor watercourses leads to growth attention to this problem in an increasing number of countries. On the example of the Slepiotka River in Katowice and Inhulets River in Kriviy Righ the aspects, on which attention of revitalisation are accented in European countries and in Ukraine, are presented. In European countries, the basis for the approach to river revitalisation is their functioning as integral ecosystems. In Ukraine, nowadays, the main focus of river restoration is on cleaning them from silt sediment. In this article the approaches to decision of river revitalisation questions are presented. The main of them are: enhancing the ecological functionality of the watercourse as an ecosystem; providing flood protection; increasing the residential, cultural and recreational value; securing permanently sustainable use of watercourses and their river valleys.

ABSTRACT. Control of the trace element content in tap water is particularly important for large industrial regions. The estimation of Cd, Pb, Cu, As, Ni, Zn, Mn, Hg, Se and Co concentration in the tap water of Kryvyi Rih city (Karachuny Reservoir) was accomplished using electrochemical methods, the most popular methods for determining the content of trace elements in natural objects and tap water. A simple and rapid method to determine trace elements in the Kryvyi Rih city tap water by inversion-voltammetry has been used. The concentration of trace elements was measured by voltammetricanalyzer AVA-2 device that implements the method of inversion voltammetry on a solid rotating electrode made of carbon material. The monitoring of the trace element content in the water of the Karachuny reservoir was carried out on a monthly basis between September 2018 and August 2019. The article presents the obtained voltamperograms of some trace elements, describes content of the trace element in tap water during the year (12 data for each trace element) and analyzes the compliance of drinking water in the city of Kryvyi Rih to the standards and normative indicators of drinking water quality.

ABSTRACT. Sustainable development is a wide area of scientific discourse based on the interdisciplinary approach that integrates research in the natural, technical and social sciences. It is a multidimensional concept that reveals complex interactions between society, economy and environment. This work highlights problems of sustainable development of old industrial regions with the dominance of the mining industry. The latter creates a high human burden on the environment and leads to ecological and social problems. One of the most important tasks of ensuring the long-term environmental sustainability of the Dnipropetrovsk region in Ukraine is utilization of highly mineralized mine water of Kryvbas. From the standpoint of sustainable development, mine water should be considered as a hydro-mineral resource of many valuable components including bromine. In this work we justify the creation of bromine production from mine water of Kryvbas. Potential profitability of the production is largely based on innovative technical and technological solutions. We examine the market and many aspects of the pilot project, including its technological, investment and economic specifics. We highlight the relevance of this project and suggest a possibility for its implementation within the regional strategy framework.

ABSTRACT. The inherently law capacity of the classically used carbon-based anode is one of the major drawbacks hindering the wide application of lithium ion batteries (LIBs) in electric vehicles. Carbon replacement with materials possessing high theoretical capacity, such as germanium (Ge) represents one of the approaches used for ensuring wider LIBs' implementation. The main disadvantage of the Ge use is its huge volume change during the lithiation / delithiation, causing Ge-based electrode pulverization, deterioration of the electrochemical properties and resulting in electrode relatively short life. Usage of Ge based nanomaterials is regarded as powerful tool for overcoming the mentioned drawbacks. This paper reviews and discusses the very recent progress in the preparation and studying the Ge nanoparticles (NPs), Ge nanoalloys and Ge-based nanocomposites as attempts for preparation of advanced anodes for LIBs.

ABSTRACT. Generating electrical energy from landfill gas (LFG) is a challenge due to its low conversion efficiency. This study investigated the potential of solid oxide fuel cells (SOFC) to produce electricity from LFG generated in pilot scale anaerobic municipal solid waste bioreactors. During the initial experiments, power generation was achieved in the SOFC with direct feeding of the LFG. Different feed flow rates (10 - 25 mL/min) and varying temperature conditions (700 - 800 °C) were also investigated to define the optimal conditions. Experiments were carried out at different feed rates and the successful results obtained from 10 mL/min and 20 mL/min feed speeds. It was also observed that the maximal power values were between 0.10 - 0.11 Watt/cm2 for all experiments. This study showed that SOFCs can provide significantly higher energy efficiencies than steam engines for LFG conversion into electrical energy.

Finally, conclusions are drawn about the potential of gallium and indium nanoparticles and nanocomposites and the further studies needed to achieve the implementation of these materials in the real life.

ABSTRACT. Oil pollution is a severing global environmental problem causing a number of adverse negative impacts on human health air ecosystem and eventually the natural income that is why soil, water, air pollution with petroleum hydrocarbons have become the focus of increasing public and research concern petroleum hydrocarbon contaminants in the air environment are caused by human activities when harmful or excessive quantities of substances are introduced into Earth's atmosphere. Sources of air pollution include gases such as carbon monoxide, sulfur dioxide, hydrogen sulfide, methane, the aliphatic and polycyclic aromatic hydrocarbons (PAH’s) fractions of petroleum are readily evolved to air during refinery and choosing the wrong storage tanks also leak to the soil change the chemical composition of spilled toxicity and biological impacts of the oil and add great difficulties to the identification of the residual spilled oil in the impacted environment and economic cost of air pollution in illness, health care costs, lost productivity so coordination between humans to conserves natural resources for future generation.

ABSTRACT. To date, the country's business climate characterizes the state of economic development and the results of its effectiveness. One of the key indicators that determine the business climate is the business confidence index (BCI). The paper proposes an approach to modeling the business climate of the country, which is based on the principles of information transparency, and makes it possible to assess the development trends of the studied indicator. The proposed approach is based on the taxonomy method, which allows one to identify the measure of influence of each factor included in the model and exclude the influence of the subjective assessment of the researcher. This approach has been tested on the example of Ukraine. The quarterly values of socio-economic indicators for the past twelve years (2008-2019) were taken as input data. Based on the correlation analysis, from the generated array of incoming data, only those indicators were selected that have a significant relationship with the business confidence index. It has been established that the GDP annual growth rate and retail sales have the greatest impact on the business confidence index. A forecast has been built for the trend of changes in the business confidence index (forecast accuracy of 87.55%), which proves the similarity of development trends in the country's business climate. The results obtained make it possible to analyze the cyclical development of the country's economy with high accuracy and reliability.

ABSTRACT. Currently realizing the new active role of the region as a sustainable development entity is a strategic direction for regional policy's development. Assessing the sustainable development of regions is an important part of such a policy and facilitates the timely identification of internal and external threats, the development of the necessary stabilization measures to prevent their negative impact, and the formation of strategies aimed at the sustainable functioning of regional systems. The economic system is an important subsystem of the region. The article proposes an approach to assess the level of regions economic development in the context of ensuring its sustainable development. It is based on comprehensive assessment technology. The sustainable economic development composite index is calculated by a weighted additive convolution of partial indicators. A feature of the proposed approach is the simultaneous use of both metric and non-metric indicators. The metric component is used to calculate the composite index values . Weight coefficients are calculated by the principal component method using the factor loadings of the first principal component. The non-metric part of the initial data is used to refine these weights. The article describes the algorithm for calculating a composite index. The practical testing of the proposed approach is presented for the case Ukraine's regions. The results lead to the conclusion about significant problems in ensuring sustainable development of the regional economy. Outcomes obtained are very helpful for the public administration bodies to develop and revise the appropriate policy for solving the sustainable development problems in each region.

ABSTRACT. Social efficiency of research (SER) conducted by higher educational establishments (HEEs) contributes a lot to improving the educational process, the quality of training of specialists, and the teaching skills of scientific and pedagogical staff. A holistic approach in the system of assessment of the efficiency of HEEs’ research, which is interpreted by the authors of the article, makes it possible for HEEs to completely adapt to market requirements, to make adequate managerial decisions and obtain relevant results. The system and structural approach was used in the study, which led to functional and effective application of theoretical provisions, scientific principles and conceptual positions for developing the author's version of forming HEEs’ holistic approach based model of SER. For the assessment of SER, a holistic approach based theoretical and analytical model has been suggested, which integrates 4 subsystems: target, provision, regulatory, management subsystem, which can be assessed by parameters, indicators and criteria of social efficiency of research results (SERR). The authors have suggested a system of criteria of SERR. On the basis of the elaborated system of criteria assessment of SERR of HEEs, the authors have constructed a structural and logical scheme of SERR assessment, which shows that on each stage of SERR development by means of comparison of the market needs and opportunities of HEEs and rational distribution of endowment funds it is possible to achieve maximization of the SERR generalized criterion value. A formal description of the main components of the constructed theoretical-analytical model of the SER has been made by means of using the economic and mathematical model and the dependence of its components has been analyzed.

ABSTRACT. It is stated that Ukraine's further economic growth should be directed by Government's Sustainable Development Strategy, the key idea of which is harmonization of three interconnected components - economic growth, environmental protection and social protection for all members of a society. The threats of waste accumulation to the sustainable development of the country were emphasized. It has been proven that the most successful way to deal with the problem of the waste is to recycle it. The feasibility of introducing an eco-project for the municipal solid waste recycling is substantiated. The complex mathematical model of profit forecast is developed. It shows the tariffs influence on profitability of eco-project on construction of the plant for municipal solid waste recycling according to inertial and innovative scenarios of economic development in Poltava region, Ukraine. Emphasis is placed on the shortcomings and gaps of the existing tariff policy on solid waste management services. There is a lack of incentives for the development of business recycling under the existing tariff policy. A single tariff should be combined uniting the services cost for the removal, sorting, processing and disposal of the waste. It is proposed to establish a single tariff without dividing by consumer categories.

It presents the calculation of the expediency of the innovation project implementation by a technopark.

ABSTRACT. There are determined directions of interrelation of enterprises’ development and economic security. The authors indicate that the main difference between definitions of an enterprise’s competitiveness and those of economic security implies that the former are mostly focused on comparing an enterprise’s development with that of its competitors, while in definitions of economic security, an enterprise’s development is considered separately from other economic entities. Economic security is defined as development, a development condition or an ability to develop. Interrelations of economic sustainability and economic security of an enterprise are considered and systematized. It is proven that essential elements of enterprises’ sustainable development include innovative activity, production provision, export of science-intensive products and development of high technology services, this providing for efficient levels of enterprises’ economic security and competitiveness. Under conditions of uncertainty, there are some basic functions of an enterprise aimed at enhancing its competitiveness and economic security including the following: achieving the optimal level of an enterprise’s resulting indicators and efficient ‘income-risk’ ratio, innovative activity, ensuring the quality of an enterprise’s intellectual capital, environmental safety and meeting required social standards.

ABSTRACT. Globalization is viewed not only as the objective, but also as the subjective process, the current version of which requires adjustments since it is characterized by the increasing inequalities and instability causing conflicts worldwide, pushing regional groups towards confrontations. Globalization is to be directed for achieving the equitable levels of development across the globe for which it is suggested to establish the situational governing board as the common platform for collaboration between the regional blocs for global economy regulation. The notions of the regional state and the global/planetary state are introduced. The interdependence of regionalization and globalization is thoroughly analysed, which results is the explanation of the logic behind the process of the multipolar world formation as opposed to the unipolar one. The main points are illustrated by the facts from the EU integration history and the calculated indicators of the major thirteen regional integration groupings covering Europe, Asia, North and South America, Africa, and two transregional organizations - Regional Comprehensive Economic Partnership and Transatlantic Trade and Investment Partnership. The contribution to the study of regionalism as the boosting phenomenon shaping the development of the world allowed to conclude that regionalization is critical for the sustainable furture of the world.

ABSTRACT. Many studies are devoted to the peculiarities of building the information society in the modern world and the problems of uneven development of information and communication technologies in developed and developing countries. This paper examines the influence of the information and communication technologies development on the social and political activities of modern society. The correlation and regression analysis has been used to identify the relationship between the Information and Communication Technology Development Index (ICT), the Human Development Index (HDI) and the Democracy Index (DI). The results demonstrate that there is a close link between the countries’ socio-political attractiveness and the level of their information and communication development. However, it is not equal for different countries, which are grouped by the level of ICT, HDI and DI. Besides, the country’s information and communication technologies level has a significant effect on the social and political development.

ABSTRACT. Under the conditions of EU association, one of the important for Georgia is to create such tax policy that shall be agreeable and settled with the economic systems of developed countries. The efficiency of the tax system depends on the optimal tax policy, according to which highly available and modern standard-oriented business environment is created. In 2017, the Parliament of Georgia passed the reform of profit tax that is aimed to free the business entities from profit tax during the reinvestment process. All the above mentioned maintains the topicality of ongoing reforms in Georgia. The goal of the research is to identify the impact of the new tax system on the Gross Domestic Product, the stream of investments, stimulation of business, and the period, after which the results of the reform will be favorable for the economic. There are various researches and scientific publications on the given issue. According to the study, the reform will produce a long-term macroeconomic effect that will mainly aim to favor small and middle scale businesses. Liberal tax approaches are advancing Georgia's investment attractiveness, reflecting an increase of investments. This work is based on Estonian experience presented in statistics and international studies. The information processed by experts and researchers helps us to evaluate the impact of this reform on Georgia.

ABSTRACT. Human capital is a key factor in the success of any enterprise. Since human capital, like other types of capital, is prone to exposure to various types of risk and an important task of any enterprise is to assess the level of human capital. This paper proposes the author's approach to the formation of the structural components of human capital. Its structure included three sets of indicators that characterize educational, intellectual and physical capital. Also, a methodological approach is proposed to evaluate the human capital level of machine-building enterprises, which consists of three interrelated stages. The methodological approach is based on a point evaluation of the indicators included in the human capital structure based on the questionnaire (polling) of the personnel of the analyzed machine-building enterprises. The assessment of the level of human capital was carried out separately for two groups of workers. It is established that the total value of the integral index of human capital corresponds to the average level for all examined enterprises and ranges from 0,463 to 0,585. It has been found that the personnel at the machine-building enterprises have a great potential for development and a high propensity for change. The advantage of human capital assessment on the basis of its structural components is the ability to determine the optimal need for human resources and forecast the cost of supporting and developing human capital.

ABSTRACT. The role of human capital in the innovative development of the Ukrainian economy, which is formed through investment in the human being, is investigated. It is determined that an indispensable condition for sustainable development of the country is the implementation of the strategy of increasing the quality of human capital, which is actively involved in innovation processes and serves as a key resource for improving the competitiveness of the national economy. Emphasis is placed on the role of the educational component of the person, introduction of the model "education during life" using modern technologies that will promote the development of creativity, creativity and professionalism of the individual. It has been researched that the implementation of innovation policy depends on the effectiveness of the state regulatory policy, on the basis of which regulatory acts are adopted. The tools of innovative development of human capital are considered. A methodological approach to determining the level of innovative development of human capital is proposed and the value of the integral index of innovative development of human capital is calculated. The innovative-investment model of human capital development in the conditions of globalization is developed and the directions are defined. To overcome the problems of inefficient development of human capital and to improve its quality, a set of measures will be proposed that will contribute to the innovative development of the economy, creation of competitive advantages of the country. Scientific novelty is to deepen theoretical provisions and to develop scientific and practical recommendations for improving the quality of human capital and its innovative development in the context of accelerating globalization processes.

ABSTRACT. Determined that achievement of certain economic security level set by management for the current time point is a necessary but insufficient condition of further development of the enterprise. When the mentioned condition is fulfilled, the degree of its personnel’s innovation activity should also be considered. The article presents further development of the methods of assessing the level of the dependent part of economic security of the enterprise's stakeholders, including the personnel, which, unlike others available, is based on estimation of outstanding expenditures. Innovation activity of the personnel is determined to depend on their attitudes to innovations. The article presents a developed economic and statistic toolkit of assessing the personnel’s probable attitudes to implementation of innovations considering the degree of recognizing the necessity of innovations and awareness of the enterprise’s activities in terms of innovations. The level of probable (expected) attitudes to innovations is taken as a basis for a combined classification of particular personnel categories. The article suggests a matrix approach to determining the type of enterprise development based on comparison of the level of economic security for the current time point and the personnel’s innovation activity.

ABSTRACT. The problem of anthropogenic impact is becoming more acute every year. The basis of entrepreneurship is to maximize profits and increase profitability ratios. However, when calculating economic indicators, changes in the natural potential and the impact of any activity on the environment are not analyzed. In developed countries, more and more emphasis is focused on socially and environmentally conscious entrepreneurship, however, business is still predominant in the world, where the result of activity is an increase in financial resources due to environmental degradation. At the same time, there is an improvement in the situation with financing environmental protection activity. An increase of the population’s consciousness is of a point– like nature, while the ecosystem continues to degrade. It is proved that the negative externalities that were described in the model by Pigou, Leontyev– Ford and others must be taken into account. The necessity of taking waste minimization and negative impact on the environment as a target function is justified. It is proposed to solve this problem systematically and to take into account the effect of the accumulation of negative implications of the impact on the ecosystem.

ABSTRACT. Abstract. The purpose of the study is to develop an economic-mathematical model of the socio-economic system, which takes into account its logistical structure and ecological viability. This allows for optimal budget planning for the new project. The methodology of the study is based on the method of J. Forster, who proposed to consider the logistics system of any enterprise as a system of reservoirs linked by material, financial and information flows. The main result of the study is as follows. The methodology is designed and developed a mathematical program that allows estimating the relative value of fixed assets of production and the number of costs for creating a retail network with the impact of the environmental components. It is shown that this ratio is determined by the value of all key parameters of the enterprise logistics system. This result was obtained through careful modeling of structural changes in the logistics system of the enterprise. All basic communications (flows) between the elements of the logistics system were also considered. Calculations were conducted for the system of the equations which have been written down in shape with discrete-time. At the same time modeling was carried out so that there were no "not physical" phenomena (such as overflow of warehouses, etc.). As a result of calculations, optimum values for all basic characteristics of the new project have been specified. The most actual has separately been considered for practice as a case of optimum planning of storage facilities. The practical importance of research consists that scientific representations about interrelation of the capacity of the enterprise with key parameters of the logistic system can form a basis for more effective planning and management budgetary and production processes at the enterprise, namely: it is more reasonable to plan scales of production and expenses on logistics creation.

ABSTRACT. The stady of corporate sustainability is becoming more relevant in the world economy, thus the connection between global economic processes and political, environmental and society problems was revealed by authors. Given research is devoted to the analysis of the processes of sustainability of Ukrainian and foreign companies. The results of studies of scientific works and interviews with different countries businessmen showed that the sustainable development of the same company should be considered in several directions, namely, in economic, social and environmental. Supporting new institutional concept research that focuses on the sector problems of company's stability, we have compared theories of corporate sustainability and corporate social responsibility and highlighted the economic dimension as a basis of company's sustainable development. As a result of our research in economic direction of corporate sustainability the Methodology of evaluation of company's sustainability potential was proposed. The suggested Methodology can ensure corporate sustainability for the strategic period. Proposed Methodology assesses the strategic potential of company's success, its competitive status and capacity potential, and transform capabilities into competitive advantages. The implementation of the Methodology of evaluation of company's sustainability potential, according to authors view point, can be proposed as the basis of strategic management in forecasting and planning processes in industrial companies.

ABSTRACT. Ensuring economically sustainable development in difficult political and economic conditions is one of the priority tasks for Ukraine. It is possible to support the country's economic growth through effective international cooperation, including by paying special attention to the processes of regional integration on the basis of trade and economic ties between integration associations. In this connection, Ukraine is forced to reorient the vector of foreign economic cooperation, in particular, the integration formations of the European Union. The aim of the article is to study the development of the processes of regional integration of Ukraine to ensure sustainable economic development, as well as determine the priority direction of its regional integration. The place, role and directions of economic integration in international relations and world politics are examined; the role of Ukraine in the processes of economic integration at the present stage of development is analyzed. Based on the analysis of the current state and development features of the EU and Ukraine, the prospects for the activation of its participation in integration processes, namely entry into the European Union, are substantiated. By analysis, the domestic market of Ukraine, the general state of development and its place in the world market are investigated. As a result, the features and barriers of Ukraine’s European integration and ways to address them were identified, as well as an attempt was made to identify the main areas of cooperation and ways to improve economic relations between Ukraine and the European Union.

ABSTRACT. The necessity of using accounting and auditing system is substantiated in the article, its main advantages are also defined. A model of accounting and audit support has been developed in the article, suitable for usage by forestry enterprises. In the system of rational forest management, accounting and auditing support of its management is of paramount importance, because it allows to monitor, document and verify for reliability all parties of financial and economic activities of forest users. In developing a system of accounting and audit of rational forest management, we are based on the fundamental categories of the classical scientific process, so its main elements are the object, subject, methods and subjects of research in the context of the relationship between the two components – accounting (by types) and economic and environmental audit of forest resources. Conducting an environmental audit in the forestry sector is complicated by the complexity of the audit object and the contradictory and multi-level relationships between its main elements. Internal audit is one of the few available and at the same time undervalued resources, the proper use of which can improve the efficiency of the enterprise and contribute to the orderliness of the management of economic processes.

ABSTRACT. Today’s realities dictate to Ukrainian companies a management philosophy that requires them not only to maintain their position in the market, but also to increase the efficiency of their operations and development in the context of favorable and unfavorable changes in the market environment, which necessitates significant amounts of financial resources. In the face of global competition and the increased turbulence of the external environment, securitization is one of the alternative tools to attract additional financing as well as to minimize risks by which financial markets can support sustainable finance in the transition to a green economy. The article deals with the essence of securitization as one of the major financial innovations of our time. It is established that this financial mechanism allows to diversify sources of financing, to effectively manage the structure of the balance sheet of the enterprise, as well as to significantly increase the level of liquidity of its assets. It also describes the main types of securitization and their impact on the structure of balance sheet indicators. The practical relevance of the study is that the authors’ highlighted areas of change in financial performance make it possible to make an smart decision on the use of a particular securitization mechanism, considering the purpose of its implementation and the capabilities of its initiators, including in the transition to a green economy. It is suggested for the successful implementation of the concept of a “green” economy aimed at achieving sustainable development goals in Ukraine, using such financial instrument as sustainable securitization through the use of the collateralized loan obligation mechanism.

ABSTRACT. The article proposes two methods for evaluating the financial efficiency of a business model of industrial enterprises. In order to evaluate the financial efficiency of the business model of an industrial enterprise, a system of single indicators for assessing the financial condition of the enterprise by such components as financial stability, liquidity and solvency, business activity and profitability was formed. Fishburne's rule weights the major components of an integral measure of the financial performance of an enterprise's business model. In addition, an integral measure of the financial performance of the business model is modeled using the fuzzy set method and taxonomic analysis, which will help to evaluate the financial performance level of the business model more objectively

ABSTRACT. In article the content of "climate risk" as risk is specified, the emergence of which is caused by human activity, which leads to pollution, resulting from industrial activity and other sources that greenhouse gases (carbon dioxide) which are capable to absorb a range of infrared radiation generate and, as a result, predetermine warming of the global atmosphere that brings to change of structure of the world atmosphere and adds natural climate instability during the certain periods of time. Due to results of the research, the theoretical generalization and author's solutions of a scientific task are offered, which appear in the development of scientific and methodical approaches and justification of practical recommendations about modernization of activity of insurance companies and reinsurers in the conditions of risks, generated by global climate changes.

ABSTRACT. The article considers the theoretical essence of the lean production concept. It has been proved that its essence lies in identifying and reducing costs of processes, and sometimes eliminating business processes that do not create added value but consume large amount of resources. The main constituent elements, tools and principles of lean concept implementation have been outlined. The possibility of implementation of lean logistics in the activity of agricultural enterprises has been considered. It has been defined that combination of lean logistics and “green logistics” is a rational way to increase both economic and ecological efficiency. The VSM tool have been offered for implementation of the lean concept. VSM maps provide a visual representation of step-by-step scenario to achieve the strategic goals of the company, representing material and information flows required to deliver a product to the final consumer.

ABSTRACT. The work is devoted to a comparative analysis complexity of traditional stock market indices and social responsible indices in the example Dow Jones Sustainability Indices and Dow Jones Industrial Average. As measures of complexity, the entropies of various recurrence indicators are chosen - the entropy of the diagonal lines of the recurrence diagram, recurrence probability density entropy and recurrence entropy. It is shown that these measures make it possible to establish that the socially responsive Dow Jones index is more complex. A comprehensive assessment of complexity reveals the nature of the effectiveness of social responsible indices and opens up new opportunities for investor risk management.

ABSTRACT. The article is devoted to solving the problem of evaluation and selection of investment projects aimed at the development of territorial communities, taking into account the concept of sustainable development. The problem of choosing from possible alternative solutions is not easy for decision makers and requires qualified justification. This is especially important in the context of decentralization reform, advancement of Ukraine towards openness of society, increase of transparency requirements of the authorities and their results. Decision making on the basis of the concept of sustainable development determines the evaluation of investment projects in terms of their effectiveness in solving problems of social, economic and environmental nature, finding a balance between these components. The peculiarity of the assessments is not so much quantitative as qualitative, which makes it expedient to use the apparatus of fuzzy logic. The fuzzy model of evaluation of investment project aimed at development of territorial community is constructed and substantiated in the work. The model is based on quantitative and qualitative assessments of the social, economic and environmental components of the concept and enables a "soft" - qualitative assessment of the investment project under consideration. Modeling results are based on the method of deciding on the choice of investment projects for the development of territorial communities. The proposed model and method are implemented using the Fuzzy Logic Toolbox application, used to substantiate decisions for the territorial community of Zaporizhzhia region, and can be used in the development of decision support systems for quantitative decision-making, variant calculations.

ABSTRACT. Constantly increasing the level of competition requires manufacturers of goods and services to individualize their products. Considering this factor, the brand takes on a new level of perception, a level of the strategic asset of the company, which allows evaluating the value of the company. With the pursuit of competitiveness and modernity, domestic companies have only in the last few years begun to view the brand as an integral part of their business, capable of generating additional profits at the expense of increased consumer loyalty. However, there are currently no standard methods for evaluating brand value, and there are some disadvantages to applying them. The article deals with modern research methods of the Interbrand and V-RATIO brand. It is revealed that the results of the calculations by different methods differ depending on the set goal: long-term or short-term costs. 19 brand evaluation criteria are considered. We propose our conceptual model of brand value estimation based on a closed system of factor analysis and modeling. The impact of the criteria on the choice of alternatives for choosing brand value strategies is suggested to be found by the Saati hierarchy analysis method. To enhance the adaptive properties of the selected criteria, it is proposed to use the mechanism of alternative strategies for increasing brand value by incorporating the Kohonen neural network process algorithm. The structure of hierarchies of influence of defined criteria on the brand development scenarios was constructed. Calculations were made by the method of analysis of hierarchies in the author's developed system, and it was found that having the resources to increase only one criterion of brand development would be the best development of leadership or internationality of the company. Based on the calculations neural network in the MATLAB, it was found that enterprise, which was researched, needed to pay attention to advertising costs or to increase brand value.

ABSTRACT. The paper focuses on monitoring and modelling of the cryptocurrency market. The application of the chosen research methods is based on the analysis of existing methods and tools of economic and mathematical modelling of time series research on the example of the cryptocurrency market. It is proved that the use of individual methods is not relevant, as they do not give an adequate assessment of the specified market, so a comprehensive approach is the most acceptable. Therefore, monitoring and modelling of some cryptocurrency pairs with different capitalization degree were implemented by fractal and recurrent methods of the financial markets. The daily values of currency pairs for the period from September 2015 to November 2019 were chosen as information basis for monitoring and modelling. The use of R/S modelling method make it possible to conclude the persistence of time series of the selected cryptocurrencies indicating that the market trends are clearly defined, the currency pair of XRP/USD has the highest level of trend resistance. To compare the obtained results, the comprehensive approach is offered using recurrent diagrams that help to determine the cryptocurrency stability. The results of modelling by the recurrent method show that the most stable cryptocurrencies are the ones with the highest capitalization, namely Bitcoin and Ripple.

ABSTRACT. The article deals with the experience of implementing ICT into language teaching and learning. Informatization and application of innovations in education has resulted in emergence of e-learning. While Moodle is one of the most popular Learning Management Systems (LMS) and it enables and facilitates the shift to the student-centered education, the article highlights its implementation and adjustment to the specific nature of teaching and learning languages for specific purposes at Kryvyi Rih National University. The article touches upon reasons for applying Moodle to language teaching/learning and its advantages as a complement to the traditional face-to-face, or classroom, mode, thus combining them into what is referred to as blended learning. Both the teachers and learners interviewed demonstrated positive attitudes to using the platform in their practices. Besides, the article touches upon Moodle-based opportunities of managing the content and monitoring students’ activities both in general and by individual courses. As Moodle is a web-based distance education platform not initially developed for language learning, the article invites discussion on advantages and disadvantages of its application to teaching/learning foreign languages and finding out which factors may allow language teachers and learners to boost its use and reach the set goals.

ABSTRACT. Ukraine, as a state striving to join on the parity basis the international community of developed and democratic countries, and first of all the developed countries of Western Europe, lacks some important prerequisites for achieving this goal. Besides several economic and political factors making obstacles for the desired achievement, of no lesser importance are the humanitarian factors, such as the monolingualism and monoculturalism of a substantial part of the Ukrainian population. They preclude unimpeded mutual understanding and mutual acceptance, as well as free unimpeded contacts, between many Ukrainian citizens and their European counterparts. In this aspect, the solution for Ukraine can be found in sustained foreign language (primarily English) lingua-cultural education of the broadest strata of Ukrainian population that could open for the people a way out in what concerns their ability to communicate freely and fluently all through the Western European space sharing with the people living there not only the language of international communication but also the cultural approaches, beliefs, and values underlying the everyday social intercourse. The article discusses the ways of developing such sustained (life-long) English lingua-cultural education for the young generation of new Ukraine. It analyzes the section of that education to be implemented at Ukrainian non-linguistic tertiary schools with the aim of designing its efficient model. That model is considered to be based on four most important foundations when teaching English as a foreign language: the principled pragmatism, or well-grounded eclecticism, in language teaching; the constructivist language learning; the foreign language immersion, and the integrated ‘language-and-culture’ teaching and learning focusing on communication culture. Interpretation of all these notions is given with a conclusion made concerning the rational approach to sustained English lingua-cultural education in the Ukrainian conditions.

ABSTRACT. The article presents a comparative analysis of the level of somatic health of students aged 17 to 22 with different levels of physical activity at Melitopol State Pedagogical University. According to the results of the evaluation of the general weekly motor activity, the time spent by the students for active physical exercises is insufficient. They belong to the group of people with low levels of physical activity. Express assessment of determination of somatic health level of students age 17 to 22 by the method of G.L. Apanasenko showed a significant percentage of students whose health level is below the average and low: 52.5% boys and 51.6% girls. A fairly wide range of individual somatic health fluctuations has been driven by health status, physical development, and functional levels of the cardiovascular and respiratory systems. Unsatisfactory status of somatic health indicators requires the development of new programs that will provide both wellness and professionally applied orientation of the process of physical education in higher educational institutions. Due to the increase in the amount of educational information, as a basis of future professional success of the modern student, there is a problem of involving students in independent motor activity, organization and carrying out of physical, sports and mass events. The analysis of these studies clearly indicates the need for constant monitoring of the indicators of physical development and somatic health of students throughout the study period. In order to objectively evaluate somatic health and to track it in dynamics, the students themselves proposed the ICT Health Portfolio developed by the authors. The implementation of such monitoring technology and information program provides an automated assessment of the functionality of the human body, and is accurate, informative and physiologically sound.

ABSTRACT. This paper examines the issues related to the implementation of an educational process based on modern information technologies use. The main purpose of it is to achieve a significant level of individualization of the educational process, taking into account the individual characteristics and capabilities of each participant of the process. The implementation of the approach became possible at using elements of the theory of artificial neural networks in the educational process. Based on the network, it is possible to build a model of the educational process; it will significantly increase the control of the teacher on the educational process. Moreover, this network can adapt to a specific education task, the individual characteristics of the student and teacher. The mathematical model of the educational process using modern information technologies and neural networks is constructed. Their use is based on the developed criteria of successful execution of various stages of the educational process. Such criteria are designed for both the student and the teacher. The characteristic of participant’s activity of the educational process is considered in the work. A numerical interpretation of this concept is proposed

ABSTRACT. The purpose of the Research Article, the materials of which are outlined in this article, is to uncover current trends in the development of environmental monitoring and the tracking of anthropogenic environmental impacts. To achieve this goal, it is proposed to use geoinformation systems to perform environmental monitoring and control, using appropriate software. For this purpose ArcGis software was used which allows monitoring the state of the atmosphere, its pollution and other deviations from the norm. The research was conducted exemplified by nine districts of Kharkiv. As a result of computer geospatial analysis, models and maps of urban pollution have been developed. In general, the intellectual analysis of geostatic models of emission distribution in the city allowed identifying and classifying zones of high concentrations of pollution and comparing them with air quality data. Methods of geostatistics transformed the data from a discrete to a continuous form of representation. Further studies in this area may be related to the improvement of geostatistical data analysis and pollution distribution prediction methods. As an example, mathematical formulas were presented to determine the atmospheric pollution index and the true or predicted pollution index, which can be determined on the basis of the data obtained and represented by elements of the ArcGis software package in a discrete and continuous form.

ABSTRACT. Geographical education in the post-Soviet countries after independence is oriented to the Western model of teaching disciplines. What positive and negative results have been obtained to date are discussed in this article. In the last four years, the educational process in schools has been focused on an updated program. As a result, an interesting question arises: how do we teach students? And this question, what subject we are studying, is moved to the background. The mass transfer of school subjects to a new model of education led to disintegration. In this article, the authors try to analyze the state of geographical education in Kazakhstan, to characterize the process of studying geographical disciplines from the seventh to the eleventh grade. As the authors of the updated textbook, we found many inconsistencies and issues that need to be addressed immediately. There is a model of geographical education, using the material of the updated program to preserve the traditions accumulated over the years of geographical education and upbringing.
