The study emphasises the widespread use of a global risk-based approach for assessing the environmental risks posed by such enterprises to both the environment and public health. This approach involves predicting potential future environmental consequences under different scenarios, with the choice of a specific method dependent on the particular conditions, objectives, and available resources.The analysis of these assessment methods reveals the prevalence of an integrated approach, which comprehensively evaluates multiple aspects of an industrial enterprise’s environmental impact. Moreover, the research underscores the importance of adopting modern technologies and strategies to enhance water supply and wastewater management efficiency for environmental preservation.The assessment of the ‘Kharkiv Coke Plant’ indicates minimal impact on land inundation issues, with little effect on groundwater quality. However, the excessive consumption of freshwater remains a significant concern, necessitating improved efficiency in the operation of the plant’s wastewater recycling systems. To evaluate the enterprise’s influence on surface waters, notably the Lopan and Udy rivers, the paper calculates the volume and flow of wastewater originating from the facility’s premises.Additionally, environmental impact assessment is conducted using key environmental indicators, including the alarm index, hazard index, and priority index. In light of the identified environmental challenges at the investigated industrial facility, including wastewater discharge into the municipal sewerage system, high water consumption, and phenol emissions from the quenching tower, the paper proposes a solution. This solution entails enhancing the plant’s water recycling infrastructure through the implementation of a closed-loop water recycling system and improving the efficiency of the biochemical plant. This approach aims to mitigate the environmental impact of the enterprise while promoting sustainable water management practices. Keywords: environmental problems, water resources, degree of pollution, enterprises.","PeriodicalId":121805,"journal":{"name":"Municipal economy of cities","volume":"104 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139186872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vertical cable tunnels in NPPs are used for laying cable lines, wires, safety system lines, connecting the equipment room, and the containment of the nuclear power plant block. The paper analyses research methods and selects options that will be effectively used to determine the temperature regime in the vertical cable tunnel of NPPs with known aerodynamic, technical, and geometric parameters and fire loads. The algorithm for conducting full-scale tests in the vertical cable tunnel of an NPP is described. Based on the research, the maximum temperature in the combustion zone is reached on the fourth minute of the full-scale tests in the vertical cable tunnels of nuclear power plants. By obtaining temperature graphs in the vertical cable tunnel of the NPP, it can be observed that the highest temperature is in plane D (800–900 °C), and it depends on the location of the control point. Thermal energy propagates more intensively in the direction opposite to the filling of the space, which is opposite to the exit of combustion products and ventilation openings. The temperature in plane C is in the range of 500–800 °C. Thermal energy propagates most intensively towards the filling to the exit of combustion products. This temperature significantly deviates from the standard temperature regime, which differs greatly from the full-scale experimental study of fires in the vertical cable tunnels of nuclear power plants. It can be concluded that the standard temperature regime of a fire is not adequate for testing the fire resistance of the structural elements of vertical cable tunnels in nuclear power plants. An important conclusion of these studies is the possibility of determining the fire resistance of building structures of vertical cable tunnels of NPPs with the selection of the most severe temperature regime, according to the conducted field test. It means that research results can be used in practice in designing and evaluating the safety of such objects.

It cannot function normally when active hostilities are taking place in the country. Therefore, the problem of determining the factors of the socioeconomic development of the state and its economic security now comes to the fore. Among them, the digitalisation of the country plays an important role. Considering the relevance of the recovery of the Ukrainian economy, which suffered a decline due to the war, it is considered appropriate to carry out a comprehensive analysis of the digitisation state of the country by modern methods. The paper is devoted to the problem of interdependence estimation of the digitisation and socioeconomic development indices of the country. The article aims to improve the complex of mathematical models for assessment and analysis of the digitisation state of the country, which will be supplemented with a model of interdependence indicators of digitisation and socioeconomic development of the state. Implementing the model will allow for determining digitalisation development directions, estimating the socioeconomic development level of the state, as well as ensuring its economic security. In the process of research, the following tasks were set to be solved: to select and form a base of indicators necessary for modelling; to develop a model; to investigate the canonical correlation between socioeconomic and digital development indicators by the canonical analysis methods; to investigate the dispersion of canonical variables observations and to find out the most significant areas of digitalisation improvement. As a result of the study, the highest correlation was evaluated between the network readiness index and the socioeconomic progress index (coefficient 0.98). The socioeconomic progress index is also related to the e-government development index (0.92) and the information and communication technology development index (0.90). Thus, the analysis performed in the paper of the correlation between the sets of digitalisation and the socioeconomic development indexes allows us to conclude the presence of a high level of their significant influence and the importance of forming a system of measures to ensure the proper level of the digital development of the country in these directions.

It is proposed to use the expert method of scenarios to assess terrorist threats to strategic objects. Ensuring the national security of Ukraine is a multifaceted problem, which includes military and political, economic and informational security, protection of the state border, and civil defence. Solving these component tasks is impossible without taking into account the possible terrorist impact on the strategic objects of the state, which include critical infrastructure enterprises, key transport communications, and military facilities. The description of any emergency requires a clear definition of the type of catastrophic event that caused it. Terrorist threats at protected strategic objects are possible socially dangerous consequences of malicious actions, i.e., terrorist acts that lead to stopping or limiting the functioning of these objects. The scenario method involves the creation of scenario development technologies that provide a higher probability of developing an effective solution. Scenarios are a set of equally compelling stories, each describing one of the potentially possible options for the future. Intrusion scenarios used in physical protection systems of protected objects consist of two parts. The first one provides a set of variants of terrorist threats, that is, expected actions of intruders against the protected object. The second is an action plan (reaction to the actions of intruders) of the physical protection system to neutralise terrorists. The process of improving the technology of developing scenarios of terrorist threats will provide a higher probability of developing an effective solution to ensure the security of strategic objects and counter terrorist threats, when possible, and a higher probability of reducing expected losses to a minimum in situations where losses are unavoidable.

A methodology project was developed, and experimental studies were conducted on the evacuation of a mixed flow of people with the presence of persons of different mobility groups to determine the parameters of their movement, including the density of the human flow, the time of following, the delay time at the door, and the average speed of the participants of the experiment, with the subsequent calculation of the evacuation time. The methodology provides for the simulation of various options for evacuating people during a fire in a separate part of the building. The article considers options for possible formations of human flows during evacuation when multiple M3 and M4 mobility groups are present, each with different percentage distributions. The obtained data were entered into the empirical database sorted into variational series based on increasing density. For each interval, the mathematical expectation was calculated, representing the arithmetic mean value for normal data distribution. The indicated results will make it possible to create empirical tabular data on the movement parameters of mixed evacuation flows. This data allows for the establishment of the dependence between the movement speed of the evacuation participants and the flow density. Addressing this scientific problem will facilitate the derivation of the dependence of the average value of the speed of the free movement of the flow of people (V0) and the density of the flow (D0), after reaching which an increase in density leads to a decrease in speed, on the quantitative composition of participants in the movement of mobility groups M1, M3, M4 and the coefficient of adaptation of the human flow to changes in its density during movement with different percentages of participants of mobility groups M1, M3, and M4.

Understanding the factors that influence this process is important for sustainable urban planning and development. This study aims to analyse and study the formation of factors influencing the development of agglomeration associations in the system of territorial planning, in particular by researching world experience and analysing relevant literature. The object of the study is the process of development of agglomeration associations, and the subject of the study is the factors that influence this process in the territorial planning system. The methods of literary analysis, statistical data analysis, and comparative analysis were used in this study. The literary analysis made it possible to collect and analyse domestic and foreign sources related to the problem of the development of agglomeration associations. The analysis of statistical data provided an opportunity to confirm and emphasise certain trends in the development of agglomerations. The comparative analysis made it possible to identify differences and common features of the development of agglomerations in different countries. In the course of the study, scientific sources on agglomeration growth and territorial planning were carefully analysed and systematised. A comparative analysis of agglomeration growth in France, Germany, Japan, China, India, and Brazil was conducted, which made it possible to identify common trends and differences. Based on the conducted research, it was established that the development of agglomeration associations is a complex process with various consequences. For the practical implementation of the research results, it is recommended to develop individual approaches to territorial planning and urban development, taking into account the specific factors of each country.

Addressing this issue entails finding a delicate balance between the needs of urban planning and the requirements for safeguarding various aspects of urban development. The article aims to study the manifestations of the influence of urban planning factors on the use of underground real estate. Urban planning restrictions constitute an essential component of any developed city, as they contribute to a structured and functional environment for residents and businesses. However, these restrictions can significantly affect the use of underground real estate. In this article, we consider what important aspects urban planning policy encompasses and how it influences underground space utilisation. The paper analyses different approaches to investigating the problems related to underground real estate usage and categorises the various types of urban planning restrictions that bear on such utilisation. Effective urban development requires an integrated approach and discussion of urban planning constraints that consider the interests of all parties: development, environment, and cultural heritage. Maintaining the right balance between the growth and preservation of values is becoming a crucial objective for urban planning and regulatory frameworks. Consequently, the impact of urban planning restrictions on the use of underground real estate requires careful monitoring and regulation within the framework of sustainable urban development. Solving this problem requires scientific research, effective interaction of all stakeholders, and the development of urban planning policies that account for various aspects of urban development and underground real estate. Based on our research findings, we provide a comprehensive overview of the possibilities of optimising the location of underground real estate objects, taking into account current urban planning trends. We also assess the prospects for utilising underground space in the modern structure of settlements.

In this context, it is crucial to highlight the importance of applying appropriate methods to assess the factors influencing the level of real estate use at the regional level, with a particular emphasis on expert and analytical methods. Spatial, functional, investment, and environmental factors affecting the use of real estate are evaluated based on these methods. As a result of the research, the methods and models for real estate use processes at the regional level are proposed. It made it possible to form a mathematical basis and identify the appropriate tools for developing a method of assessing the level of real estate use and creating a quantitative basis for developing measures to improve the efficiency of its use at the regional level. By employing the expert evaluation method, an analysis of real estate utilisation indicators at the regional level is conducted. This analysis enables the formation of a concrete quantitative basis for further developing an appropriate evaluation method. It is noticeable that this approach made it possible to identify and evaluate the current situation and also to create the basis for forecasting future indicators of real estate use. In addition, mathematical modelling is used for detailed data analysis and determination of relationships between various factors affecting the use of real estate. It allowed us to understand which factors have the most significant influence on the efficiency of real estate use and the order of their interaction. As a result of the study, scientifically based recommendations on increasing the efficiency of real estate use were developed.
