Large Cities Of Ukraine Research Articles

Шляхи оптимізації кількості індивідуального транспорту в обмежених можливостях вулично-дорожньої мережі

An analysis of scientific research was conducted in the direction of reducing the negative impact of the use of individual vehicles on the street and road network of cities. In order to solve the problem of transport oversaturation of public transportation systems, the foreign experience of limiting the use of individual vehicles on the street and road network of cities was analyzed. The main directions of restrictions on the use of individual vehicles on the street and road network of cities have been established, including restrictions on the operation of individual vehicles depending on the number of passengers in the cabin, the digital configuration of the state license plate, and the presence of vehicle certification. Methods of limiting the operation of individual vehicles in the busy part of the city were also considered. These measures are aimed at reducing the intensity of traffic in cities and increasing the filling factor of the vehicle interior. Considering that a large share of individual vehicles used in Ukraine belongs to Euro-2 and Euro-4 environmental standards, their use significantly worsens the environmental situation in large cities. Approaches aimed at increasing the use of public transport and other alternative modes of transport for transporting passengers in cities are summarized, which reduces the load on the street and road network and improves the environmental situation. To solve the described problems, it is necessary to use a comprehensive approach, in particular, to apply measures of both a regulatory and an informational nature, primarily to popularize the use of public transport. The proposed measures to solve the described transport problems will improve the comfort of transport connections for all road users and the environmental situation, especially in large cities of Ukraine.

ГРОМАДСЬКИЙ ТРАНСПОРТ: ОРГАНІЗАЦІЙНО-ЕКОНОМІЧНІ І СОЦІАЛЬНІ ЗАСАДИ ФУНКЦІОНУВАННЯ

The article shows that the integral function of public transport is to promote social justice, accessibility of transport services for the general population and environmental sustainability. The public transport system has been proven to be efficient and competitive by helping to reduce congestion, pollution and social isolation, as well as ensuring accessibility to transport services and mobility for all city residents. Strategies for overcoming the shortcomings of the fixed infrastructure of public transport in terms of smart planning, implementation of flexible management systems, constant renewal and modernization are justified. It has been proven that the following will contribute to improving the mobility of city residents and reducing the problem of disconnection between different transport subsystems: integrated payment through the introduction of a single ticket system or cashless payment technologies; development of transplant nodes; facilitating movement between different public transport systems; integrated planning of urban development by taking into account the interaction of different types of transport. Ways to improve the pricing mechanism for public transport services based on the introduction of social justice approaches to their pricing and tariff differentiation are proposed. The importance of ensuring the effectiveness of the use of subsidies to support public transport in terms of its accessibility as a socio-economic type of activity for city residents has been proven. It is shown that the development of supporting subsystems of public transport management in large cities of Ukraine will be facilitated by the implementation of measures to ensure its availability, efficiency and sustainability. Public feedback has been proven to be an important component of effective urban public transport management and helps create a more efficient, accessible and convenient transport system for all city residents. It is also shown that the creation of a single public transport management body in the city will ensure a holistic approach to planning routes, transport schedules and tariffs, which will contribute to a more efficient and convenient service for city residents.

Study of time indicators of public transport operation depending on the season of the year

Mobility problems in large cities of Ukraine and Eastern Europe are complicated by the fact that the increase of private transport volume significantly exceeds street and road network`s capacity. This is most noticeable during peak periods in terms of daylight hours and throughout the year. From the point of sustainable mobility view, this negative phenomenon significantly affects urban public transport, which does not have separate dedicated traffic lines. This article analyzes the issue regarding the deterioration of the transport situation in large cities. The reason for this is the increase in traffic on main streets during the day peaks, as well as the presence of seasonal traffic factors. If the issue of the occurrence and traffic jams duration and the increase in the correspondence time of private transport is sufficiently studied, then the problems of changing the schedules of public transport and taking into account the increase in the trip duration depending on the time of year need to be clarified. The routes of public transport, which do not have a separate infrastructure and move in the general flow together with private cars, were chosen for the study. According to the results of remote monitoring of public transport, a change in the trip duration and time lost due to the boarding and disembarking of passengers on similar trolleybus routes in different seasons was established. Based on the obtained data, a matrix of trip duration unevenness coefficients for public transport routes was formed, and a measure of the seasonality effect on these indicators was established. The obtained results make it possible to quantitatively determine the influence of the season and time of the day on the change in the trip duration, which can be applied in further studies using simulation tools and for practical use in drawing up seasonal traffic schedules. The results of the research complement the currently relevant scientific works, which concern the problems of seasonal mobility, as well as the influence of the social infrastructure objects functioning (schools, kindergartens, and other educational institutions) of cities on the peak load of the street and road network, which extends the duration of traffic not only for private but also public transport.

INCREASING THE ENERGY EFFICIENCY OF ELECTRIC DRIVES OF SUBWAY CARS

The article proposes the use of a frequency-controlled drive for regulating asynchronous electric motors used on subway cars. The proposed solution creates all the grounds for increasing the energy efficiency of electric cars and, in general, the entire metro. Taking into account that the subway is one of the most used types of urban transport in large cities of Ukraine and at the same time consumes a significant part of electricity, therefore, in the conditions of rising prices for energy resources, these issues become the most urgent. It is shown that the methods of regulation of subway engines are not covered widely enough in scientific research, but the methods of increasing the energy efficiency of drives generally accepted in industrial spheres are a developed direction. This reveals the possibilities of integrating the developed methods for application on subway cars. The use of a frequency converter, which changes the frequency of rotation of the motor rotor by changing the frequency and amplitude of the supply voltage using vector and scalar control, is a generally accepted method of motor regulation. There are a number of conflicting findings in research regarding the use of scalar or vector control, with some favoring the induction vector control system. However, a clear regulation is not required to regulate the operation of metro engines. Therefore, the article considers scalar control, which has not lost its importance due to the ease of implementation and adjustment and is used in various areas of industry and transport. The parameters of the STDa 280-4B-UK type STDa 280-4B-UK traction asynchronous traction motor with a capacity of 180 kW, manufactured by the EMIT Cantoni Motors company, which are installed on subway cars of the 81-7036/7037 series, were used for the study. The parameters of the T-substitution scheme of the asynchronous electric drive and the numerical values of the vectors of the asynchronous motor were calculated. To analyze the operation of an asynchronous motor, the article uses the mechanical characteristic of the dependence of the motor torque on slippage at certain frequency values. It has been established that an asynchronous motor can operate stably only in a limited slip range, when the moment reaches its maximum value and the motor stops, as it has a load limit. The main reason for this is the increase in the influence of the active resistance of the stator winding when the supply voltage frequency decreases. The solution to this problem is the introduction of IR-compensation into the control system of the electric drive, which provides positive feedback on the stator current acting in the voltage channel. To demonstrate the effect of IR compensation, a comparison of mechanical characteristics was made before and after its introduction into the control system. Therefore, it was proved that the application of IR compensation is a promising direction of work, as the value of the electromagnetic moment increases significantly in the case of a low control frequency. Keywords: energy efficiency, asynchronous electric motor, subway, electric drive, scalar control, IR compensation.

Специфіка господарських відносин у теплоенергетиці України

The main directions of Ukraine’s development in the medium term are the recovery and development of the country after the russian armed aggression, as well as the reform of the mechanisms for managing and regulating the economy in general and the thermal power industry in particular in accordance with the criteria set for accession to the EU. The aim of the study is to identify and generalize the specific features of economic relations in the thermal power industry of Ukraine. The article proposes a classification of factors that can be used to characterize the heat supply system of a particular settlement; the Ukrainian legislation regulating relations in the field of heat supply is studied; the prerequisites for reforming the heat supply sector in the direction of creating regional thermal energy markets are determined. The features of the organization of heat supply in the regions and settlements of Ukraine by types of energy carriers and the structure of thermal energy production are studied (steam or hot-water boilers, combined heat and power district heating, thermal power plants, nuclear power plants). The structure of thermal energy production in some large cities of Ukraine is analyzed. It is determined that an important feature of activity in the field of thermal supply is the centralization of capacities. An analysis of thermal supply systems in large cities of Ukraine has been carried out and it has been proved that the simultaneous use of both large generating capacities and small autonomous boiler houses is typical. Based on the study of existing projects of new buildings from the Database of Energy Certificates of the State Agency on Energy Efficiency and Energy Saving of Ukraine, it is proved that in recent years, in the design and construction of new residential buildings, there has been a tendency to abandon district heating. The features and priority of the use of various heating schemes in residential new buildings of the country are determined. The ownership structure of economic entities in the sphere of district heating of communal energy in Ukraine is analyzed. The number of unprofitable and profitable enterprises of thermal power engineering is studied in the context of forms of ownership. The features of economic relations in the thermal power industry of Ukraine are generalized, which generally characterize the specifics of the organization and functioning of this sphere and constitute the basis for its further reform and post-war development

ENVIRONMENTAL ASSESSMENT OF THE ROAD TRANSPORT IMPACT ON THE ENVIRONMENT

Environmental impact assessment of road transport is a serious problem that needs an immediate solution. Intensive development of road transport is associated with an increase in anthropogenic load on the environment in the form of exhaust gases containing more than 200 pollutants, waste generation, pollution of water bodies and soils. This problem concerns not only the environmental assessment of the state of cities and settlements, but also the assessment of the state of intercity roads, roads passing through natural areas and protected areas. This problem is especially acute in industrially saturated centers and large cities of Ukraine. In this regard, the issues of improving methods for assessing the impact of vehicles on the environment are being actualized in order to find reserves for reducing the ecological and economic damage to the biosphere. Environmental impact assessments carried out in accordance with state legislation are components of the environmental assessment system. The paper shows that when assessing the environmental impact of road transport, the full life cycle of a motor vehicle should be taken into account. Therefore, the work conducted a study of the life cycle of a car from mining to utilization of a motor vehicle and assessed its impact on the environment. Evaluation of production processes and products for the full life cycle of a car is very difficult, as it is associated with the collection of information about many production processes taking place, including outside the enterprise. It should be noted that the information obtained when assessing a vehicle for the full life cycle allows us to invent ways to improve the design of the car and technological processes of its production, as well as reduce the negative impact on the environment. Therefore, the work identified the main parameters and factors influencing the environment of road transport. Possible mathematical models of the impact of road transport on the environment, in particular on the hydrosphere, are considered.

Mapping of enviromental pollution of air in Lviv

The condition and composition of air in Lviv are influenced by two main factors: the introduction of pollutants into the atmosphere through various sources and harmful physical effects on it. The latter includes radiation, sound vibrations, noise, and so on. These and other factors disrupt the optimal conditions of the air, which negatively affects human health and the condition and development of animals and plants. The main sources of pollutants in the air of Lviv are as follows: dust — vehicles, woodworking and building materials industry; sulfur dioxide — industrial enterprises, carbon monoxide — vehicles, thermal power plants; nitrogen dioxide — heat power companies; formaldehyde — motor transport, woodworking industry. Today, emissions from mobile sources are the biggest air pollutants in the city. The chemical composition of emissions from mobile sources of pollution is characterized by the predominance of carbon monoxide (up to 74 %), nitrogen compounds, and hydrocarbons (12 % and 11 %, respectively). Today the state of atmospheric air in large cities of Ukraine and, in particular, in the city of Lviv is at an unsatisfactory level. The main problems in this area are the progressive nature of the negative impact on the ecological state of the environment and human health. As there is currently no interactive cartographic material that can visualize the problem of environmental pollution, the main purpose of this work was to create an interactive web map of the quality of life of the population of Lviv in terms of air pollution. To achieve this goal, we collected and systematized geospatial statistical cartographic materials on the ecological conditions of the air in Lviv. The necessary software for the development of an interactive map of air pollution has been selected, and its possibilities have been studied. An algorithm for loading geospatial data into the created web resource has been developed. A template of applications for creating web maps of air pollution in Lviv was selected according to the indicators of 2020, which were measured at 30 crossroads of the city. Thus, two interactive web maps of air pollution in Lviv were developed in the environment «Google My Maps» and «ArcGIS Online».

THE PROBLEM OF EVALUATION OF INDIVIDUAL PERSISTENT ORGANIC POLLUTANTS EMISSIONS FROM ROAD TRANSPORT (ILLUSTRATED BY THE CASE OF ODESSA INDUSTRIAL-AND-URBAN AGGLOMERATION)

One of the main environmental polluters, especially in large cities of Ukraine, is road transport. In particular, road transport is one of the main sources of persistent organic pollutants in the environment. Therefore, monitoring of air pollution by road transport is one of the most relevant questions in Ukraine, especially considering its intentions to join the European Union. Analysis of the regulatory and legislative frameworks of Ukraine shows that, unfortunately, today, there are no regulatory documents that motivate to reduce the load of mobile sources, including road transport, on the environment. Moreover, even though the only methodology for calculating pollutant emissions from mobile sources expired in 2015, no new methodology has been developed yet. This paper calculates the masses of pollutants formed during the combustion of gasoline and diesel fuel, and proves the necessity to take into consideration persistent organic pollutants when assessing the toxicity of exhaust fumes, considering their cumulative effect and half-life. The calculation was performed according to European and national (Ukrainian) methodologies, which are supplemented by the calculation of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) formation. Using the relative hazard factor, the relative masses of these substances are calculated, the obtained masses of all components of the exhaust fumes are ranked, the contribution of each component to the toxicity of emissions is revealed. Using emission factors, the specific emissions of these persistent organic pollutants during the combustion of diesel fuel, gasoline, liquefied and compressed gases are calculated. By the results, the types of organic fuels with the highest priority for use by mobile sources are identified.

WAYS OF ACTUALIZATION OF NATIONAL PERCEPTION OBJECTS OF ARCHITECTURE

Problem statement. Today in Ukraine the mechanisms of public influence on decision-making regarding the development of urban ensembles and cities in general continue to be formed. At the same time, the level of education of ordinary citizens in current trends in architecture, design and urban planning remains quite low. This affects the general semantic state of the architectural content of cities and results in a literal repetition of the visual forms of the XIX century in modern buildings, especially in the central (historical) parts of Ukrainian cities. According to the hypothesis of this research, the solution to this problem is in the creation of a system of free basic architectural education at several different levels. Purpose of the article. The main purpose of this work is to determine ways to update the perception of architectural objects by residents of Ukrainian cities. The objectives of the study are the analysis of publicly available methods of obtaining basic architectural and urban education and their classification, the definition of rational means to increase the general level of awareness in the field of architecture and urban planning. Conclusion. Due to the extraordinary breadth and heterogeneity of the population of large cities of Ukraine, achieving a global departure from inauthentic and irrelevant architectural and urban principles and update the national perception of architectural objects and architecture in general is possible only through introducing a set of actions aimed at a specific target audience (TA). In this study, in order to simplify, only four basic TAs are identified, but in further developments they need to be detailed more to achieve a better actual result. In the general context, the most important will be TA1 (students) − an audience that can begin to receive basic architectural knowledge, sufficient enough to understand the main trends in architecture and urban planning.

Повікові відмінності у тривалості життя й смертності населення великих міст України

The aim of this paper is to identify the age-specifi c characteristics of the mortality in the large cities of Ukraine and their contributions to the changes in life expectancy in these cities. The article presents the results of a comparative analysis of the dynamics of life expectancy from 2002 through 2019 in six cities: Kyiv, Kharkiv, Odesa, Dnipro, and Donetsk. It is shown that most of the large cities have generally experienced higher life expectancy than other urban settlements in Ukraine, but there is a signifi cant variation in the levels and changes in life expectancy across cities. Overall, the study established the vanguard position of Lviv and Kyiv in terms of life expectancy, although these cities, as well as Kharkiv, showed a slower increase in life expectancy in 2002-2019. In contrast, Dnipro and Odesa, as well as Donetsk (up to 2014) having lower life expectancy and wider diff erences by sex demonstrated the pronounced improvement in life expectancy during that period. In recent years, there has been a trend towards narrowing the gap between cities, and this convergence is occurring more rapidly among men than among women. In 2002, the gap between cities with the highest and lowest life expectancy was 5.4 years for males and 2.6 years for females while in 2019 it was reduced to 2 years for men and 1.6 years for women. We made a decomposition of diff erences in life expectancy at birth between the cities in 2002 and 2019 to assess the age-specifi c mortality contributions into disparities between urban areas. The results have revealed that across almost all cities these diff erences are mainly driven by excess mortality in working ages. Also, we found that excess mortality in the middle working ages and under 1 year of age appeared to be the important factors of lower life expectancy in Donetsk compared to Lviv and Kyiv. Odesa and Dnipro are lagging behind by survival rate not only in the older but also in young working age groups, and Kharkiv has slightly higher mortality among older people (in comparison to Lviv and Kyiv). Th e conclusion is made that the main gradient of diff erences in life expectancy between the large cities has been determined mainly by deaths in working ages, i.e. mostly driven by health-related behavior and lifestyle. Nevertheless, a gradual shift in urban life expectancy diff erences is now taking place towards mortality in older age groups, i.e. more determined by the eff ectiveness of treatment of chronic diseases. Th e issue of data quality is also considered. In particular, the confi dence interval of the probability of dying in the fi rst year of life in the six selected cities is estimated to determine the accuracy of these indicators.

Ретроспективний порівняльний аналіз фізичного розвитку дітей середнього шкільного віку

Objective: We determined the morphological indicators of 12-year-old schoolchildren in Lviv, established the differences between the anthropometric parameters of the children's population from other large cities of Ukraine, and assessed the trends in physical development changes over a long period. Materials and methods: According to the conventional methods of anthropometry, we examined 348 12-year-old schoolchildren (including 172 boys and 176 girls) studying at Lviv city general education institutions. Results: Gender peculiarities of morpho-functional development of 12-year-old schoolchildren in the large cities of Ukraine were revealed. They reflect the active endocrine remodeling of children, which is primarily inherent in the performance of girls. The values of individual anthropometric parameters, both among boys and girls, were determined to be significantly higher (p <0.05) than the National criteria (2013). At the same time, the height of Kyiv schoolgirls is smaller (p <0.05) against the national norms. During the analyzed period, pronounced accelerative processes were observed in the development of the 12-year-old children’s population in Kharkiv and Odessa, which indicates a certain dependence of the processes of growth and formation of the organism on the climatic and geographical conditions of habitat and the level of industrial development of the territory. The average statistical parameters of the basic indicators of physical development of Lviv schoolchildren are lower than the similar parameters of 12-year-old children in Poland. Conclusions: The obtained results of the study confirm our previous assumptions about the necessity to work out the regional standards for anthropometric indicators of middle age schoolchildren at the regional level and recommend to use them in the assessment of children's health by family doctors and pediatricians. In the future, it is planned to expand the list of major cities in Ukraine selected for our study, and increase the number of sample groups of 12-year-old schoolchildren, which will increase the level of statistical reliability of the results.

Influence of global climate change on air pollution in urbanized areas and spread of COVID-19 morbidity

The purpose of this paper is to confirm for the conditions of Ukraine the hypothesis of a number of foreign authors on the relationship between the presence of air pollution by aerosol particles in urban areas and the number of patients with COVID-19. On the example of the main large cities of Ukraine the analysis between temperature factors, dust pollution of the atmospheric phenomena and processes of distribution of morbidity of the population on COVID-19 is made. The linear dependences in the logical coordinates between nature are obtained due to the confirmation of the cases of morbidity and the index of aerosol pollution of the atmospheric air of urban areas by solid private particles PM2.5 (AQIPM2.5). The correlation coefficients of the obtained dependences are in the range of 0.65–0.91. These data suggest the possibility of unification of data for the country for different climatic zones to assess and predict the incidence of population depending on air pollution in urban areas and climatic conditions, and may be promising in the future to find ways to reduce the impact of aerosols in the air on the human body and the purpose of finer cleaning in production processes and air exchange technologies in modern buildings and structures. According to the authors, there is a need for further research on the impact of humidity and the impact of the percentage distribution of natural and anthropogenic aerosols in the air of urban areas. Such studies will further make more accurate predictions about the impact of air pollution on human health in the context of global climate change.

Evaluation of the quality of medical care in cases of death from acute blood loss (according to data of forensic-medical examinations)

The peculiarities and specificity of the medical field complicate not only the assessment of quality and timeliness of medical care, but also the correctness of the choice of the method of treatment and diagnosis of the disease. The number of forensic medical examinations in «medical cases» has the tendency to increase, and experts in this case face difficulties with forensic medical assessment of medical care provision. Forensic medical analysis of the medical care provision to patients who died of acute blood loss, based on examinations of different forensic medical bureaus of Ukraine has been analyzed. The aforementioned examinations related to the corpses of people who died as a result of acute blood loss, including shock (150 from the total number of 6129 medical examinations were selected). This cause of a death was chosen as one of the leading causes of death in trauma (including a combination with shock). When evaluating gross medical care defects that were found during the examinations that influenced the result, 40.0% (60) – in the form of improper provision (action) were noted in 10 cases (the case of incorrect diagnosis made by the doctors due to underestimation of examination data), defects in the form of non-provision of medical care (inactivity) – in 83.3% (15 cases). In the statistical analysis of defects in the provision of medical care, the majority of cases were connected with delayed provision of medical care – 41,7%. Defects in cases of blood loss were under the following conditions: a) lack of instrumental research, medical treatment and surgery, b) lack of medical treatment and surgery by indications (each of 3,3%). When considering the reasons that led to defects in cases of blood loss, the isolated underestimation of the examination data was in 16,7% (25), a combination of reasons: a) underestimation of the examination data together with the underestimation of additional research data – 16,7% (25); b) underestimation of the examination data together with the negligent attitude to the patient who had a sloppy appearance – 6,7%. The unprofessional nature of the medical staff was in 16,7% of acute blood loss. When providing medical care in cases of death from acute blood loss, defects in the provision of medical care are made by experienced medical professionals in city hospitals (especially large cities of Ukraine), where there are adequate conditions for the provision of medical care, more qualified specialists of different profiles, and there are protocols for providing medical care in acute blood loss.

INTELLIGENT HIGH-SPEED PASSENGER ELECTRIC TRANSPORT (ISET-150) FOR LARGE CITIES OF UKRAINE

The high-speed passenger transport development is one of the most important tasks for the successful functioning of any large or largest city transport system. The modern society of the biggest cities-megalopolises needs a constant increase in the volume of transport communications. This requires an increase in costs to improve the infrastructure of the transport network, turning it into a flexible, highly manageable logistics system. However, this significantly increases the risk of investment, if one does not take into account the patterns of development of the transport network, the distribution of load on its sections. Ignoring these patterns leads to frequent traffic jams (transport congestion), overloading, an increase in the accident rate, and a complete dependence on the cost of oil products. Lack of developed infrastructure for road transport and low-speed public transport significantly hampers economic development. Therefore, a radical increase in public investment in stimulating the urban economy would necessarily include modernization of transport infrastructure. All infrastructural activities should be carried out on the territory of the country – thereby creating new jobs and strengthening the industry. Well-chosen infrastructure projects that provide conditions for economic development for decades and for many generations represent the best use of public debt capital.
 For creation in large cities of Ukraine, especially with difficult climatic and geological conditions, with difficult climatic and geological conditions, as well as with a poorly developed highway system, a new overhead electric high-speed passenger, economy and environmentally friendly, transport, with cabins, is proposed.
 To organize the safe movement of controlled crews with passengers, the theory of saturated traffic flows was used, which describes the movement of crews in a stream as a continuous change in the states of acceleration, uniform movement and braking, i.e. synchronized three phases «start-go-stop» in one control algorithm.

Recreation and Urban Tourism: A Common Problem and the Prospect for Solving

One of the main rapidly developing directions of tourism both in the world and in Ukraine in particular is urban tourism. As centuries ago, so nowadays, the cities are the goal of many travels, and the territorial recreational systems based on them are the most developed ones, which is explained by the high concentration of tourism resources in a conventionally limited space. Despite all this, in the sphere of urban tourism in terms of a territorial recreational system there is an uneven provision of recreational demand for communication with nature due to the insufficient number of natural recreational objects. As a solution to the common problem for recreation and urban tourism, it is proposed to implement a number of measures consistently both at the State level and at the level of local authorities or local self-government bodies, namely: to create conditions under which private and communal enterprises would be interested in the creation and development of natural recreational formations in the form of parks, gardens, squares, embankments. The program for the development of natural recreational spaces in cities – i.e., tourism centers – envisages that private and communal enterprises that will create these natural recreational spaces will carry out reconstructions of the already existing formations and will have the opportunity to engage in such natural recreational formations with commercial activities related to the organization of the provision of recreational services. In addition, it is important to strengthen the State supervision over compliance with the State sanitary rules for planning and development of settlements, because, in terms of landscaping, large cities of Ukraine have long failed to meet the requirements. At this, one considers appropriate to involve scientific and educational institutions related to tourism and recreation in the design of these natural recreational formations, which will allow to implement tourism in the city on not only practical, but also on scientific basis. It is believed that in case of materialization of the proposed program, the city will receive additional centers of attraction for tourists, which, in turn, will have positive consequences for the further development of cities as centers of tourism and recreation.

РИНОК КОНСАЛТИНГУ В УКРАЇНІ ТА ПЕРСПЕКТИВИ ЙОГО РОЗВИТКУ В РОЗРІЗІ ЦИФРОВОЇ ЕКОНОМІКИ

The article examines the relevance of consulting and its services in Ukraine, taking into account the crisis phenomena on a global scale and the complexity of doing business in Ukraine. The basic concepts and participants of consulting interaction in the process of rendering consulting services are determined. To identify the features of the current state and development opportunities of the consulting market in Ukraine, statistical and economic research methods used. The assessment of the degree of maturity of the consulting market in Ukraine, according to the results of which this market defined as immature. The activity of companies in this market as such, which accompanied by unstable processes of organization and functioning, has been determined. The uneven development of the structure of consulting services is largely due to the presence of institutional problems, the underdevelopment of the markets for certain types of consulting and the concentration of consulting companies in large cities of Ukraine. Market development can be associated with the requirements of digitalization: the development of new types of consulting services, new methods and techniques of market influence, the use of new information and communication technologies, internationalization and globalization of business. To implement these areas, it is advisable to form a professional consulting institute, which will provide the rules of the game for all participants in the consulting interaction. It recommended to position consulting at the legislative level as an important element of the innovation infrastructure of the National Innovation System of Ukraine. In these circumstances, the consulting activities will carried out within the framework of the presented types of consulting in accordance with the recommendations of the European Federation of Associations of Economic and Management Consultants. This will ensure the network interaction of all participants in innovative activities on the principles of public-private partnership, and will contribute to the development of enterprises in Ukraine.

ВЕБ-КАРТОГРАФУВАННЯ ЯКОСТІ ЖИТТЯ НАСЕЛЕННЯ М. ЛЬВІВ ЗА ПОКАЗНИКОМ ЕКОЛОГІЧНОГО ЗАБРУДНЕННЯ АТМОСФЕРНОГО ПОВІТРЯ

The condition and composition of atmospheric air are influenced by two main factors: the introduction of pollutants into the atmosphere through various sources and harmful physical effects on it. The latter includes radiation, sound vibrations, noise, and so on. These and other factors disrupt the optimal state of the air, which negatively affects human health, the condition and development of animals and plants. The main sources of pollutants in the air of Lviv are: dust – vehicles, woodworking and building materials industry; sulfur dioxide – industrial enterprises, carbon monoxide – vehicles, thermal power plants; nitrogen dioxide – heat power companies; formaldehyde – motor transport, woodworking industry. Today, emissions from mobile sources are the biggest air pollutants in the city. The chemical composition of emissions from mobile sources of pollution is characterized by the predominance of carbon monoxide (up to 74%), nitrogen compounds and hydrocarbons (12% and 11%, respectively). Today the state of atmospheric air in large cities of Ukraine and, in particular, in the city of Lviv is at an unsatisfactory level. The main problems in this area are the progressive nature of the negative impact on the ecological state of the environment and human health. As there is currently no interactive cartographic material that can visualize the problem of environmental pollution, the main purpose of this work was to create an interactive web map of the quality of life of the population of Lviv in terms of air pollution. To achieve this goal, we collected and systematized geospatial statistical cartographic materials on the ecological state of the air in Lviv. The necessary software for the development of an interactive map of air pollution has been identified and its possibilities have been studied. An algorithm for loading geospatial data into the created web resource has been developed. A template of applications for creating web maps of air pollution in Lviv was selected according to the indicators of the I and II quarters of 2020, which were measured at 30 intersections of the city. Thus, two interactive web maps of air pollution in Lviv were developed in the environment "Google My Maps" and "ArcGIS Online".

RESEARCH OF THE MARKET OF MINI APARTMENT

The purpose of the article is to investigate the development of a new segment of the real estate market in urban development projects. The definition of a mini apartment - the gostinka. The analysis of the world market of mini-apartments is carried out. There are questions of living of different social groups in society in mini-apartments. A classification of mini-apartments has been developed. Factors significantly affect the cost of a mini-apartment. Conclusions are made about the future market of mini-apartments in the city economy The development of the market of mini-apartments can be considered as a new social phenomenon. Many social groups have access to the purchase of a mini-apartment. The residential real estate market is in a difficult stage now. The economic crisis has had a strong impact on stakeholders. The market of mini-apartments in Ukraine is a new and currently unexplored social phenomenon. The market of mini-apartments is of great importance for urban development and has high uncertainty in further development. Therefore, the development of the market of mini-apartments poses many problems for urban development in the future Today in Ukraine in the real estate market of Kharkiv increased activity in such a segment of real estate as mini-apartments. The results of the research show that the cost range of 1 sq.m. for such objects is very large and ranges from 300 to 1000 US dollars. Which is 2 times lower than the average market prices for typical apartments. Let's analyze the primary and secondary markets of mini-apartments. The houses in which the mini-apartments are located can be characterized. Mini-apartments in reconstructed houses are of great interest to stakeholders. Here they are much lower than their cost. Mini-apartments are now actively bought by the following social groups and categories of people. Mini-apartments in reconstructed houses are of great interest to stakeholders. Here they are much lower than their cost. The classification of mini-apartments was carried out according to the parameters that significantly affect the prices in the studied segment.
