To achieve the stated aim, the authors applied a comprehensive approach, which included an in-depth study of recent injury trends, identification of the main causal factors, and a thorough examination of the risks affecting working conditions and leading to injuries. The research methodology included a variety of tools, such as a deep analysis of statistical data on injuries in the context of an industrial enterprise, a review of internal documentation, and an evaluation of risk factors. The study results provided a detailed picture of the changing trajectory of injuries among industrial workers, which is closely related to their length of service and experience at the enterprise. Based on this understanding, we derived a specific risk assessment formula that synthesised the relationship between injuries and length of service. In addition, a thorough analysis of the structure of injuries during different shifts revealed a pronounced tendency for accidents to occur in the evening and at night, partly due to the psychological and physiological stress experienced by employees during these periods and the impact of microclimatic working conditions. To enhance the effectiveness of the risk assessment methodology, we proposed to integrate a comfort factor coefficient that shows the microclimatic factors’ impact on occupational safety and injury rates. These efforts have resulted in an improved risk assessment formula that can provide a more accurate prognosis of injury incidents and help optimise occupational health and safety protocols for employees at industrial enterprises. In addition, using statistical data, the study determined the cause-effect relation between risks to industrial workers, shown through the visual representation of an Ishikawa diagram, thus providing a further perspective for risk assessment in the enterprise.\u0000Keywords: injuries, risks, injury analysis, mining and processing plant, industry.","PeriodicalId":121805,"journal":{"name":"Municipal economy of cities","volume":"56 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140735767","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}

This issue is quite relevant in our time. As a solution, there has been a proposal to use geographic information systems (GIS) and a unified geodatabase to provide local governments, municipal organisations, and citizens access to reliable information about the urban area. This information has to be systematised, structured, and stored for efficient use. Experts suggest utilising a geodatabase as a primary tool for managing massive amounts of spatial information to solve these issues. The analysis shows that this is the direction that most European and American cities have chosen. As a result of the study, the authors propose the geodatabase structure for local-level urban planning documentation. It defines a set of objects, attributes, relations, and topology rules used to represent urban planning documentation in electronic form (in the form of a city GIS). Such an approach will allow for reliably storing all the diverse information necessary for the city’s life, analysing this information, and making the right management decisions. In this study, the authors analysed existing geographic information systems of some large cities. We defined weaknesses and strengths and found out based on which software products these city GIS were developed. Then, we proposed the main structural elements (layers) of the unified geospatial database of the city GIS that would ensure the solution of all issues related to the existence of a modern city. The authors prove that the combination of a clear structure of the geodatabase, convenience, and data relevance can determine the success of city GIS, making it a core tool for ensuring harmonious development and improving the quality of life in the city. Only such an approach will facilitate the creation of a technologically advanced urban environment that will meet the modern requirements and needs of citizens.\u0000Keywords: geoinformation technologies, geoinformation system, database, protection of historical heritage, urban planning.","PeriodicalId":121805,"journal":{"name":"Municipal economy of cities","volume":"5 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140738259","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}

Impedance is a complex parameter that characterises the interaction of the electric current with milk. The authors have developed a methodology based on the specified method to assess the quality of dairy products and have created a hardware and software complex that makes it possible to analyse the quality of dairy products. The research, conducted using the developed hardware and software complex, revealed several regularities characterising different types of milk. These regularities demonstrate the relationship between the impedance signal and the milk fat index. Analysis of the obtained data allowed us to identify differences in impedance between samples with varying fat content and origin from different manufacturers. The developed experimental setup prototype enabled the following research stages: checking the change in voltage during the passage of an alternating electric current through milk. This work used the AFS Sensor DAQ data acquisition system, designed for sensor control projects and which runs with NI LabVIEW software, for data output. The authors tested the installation while investigating the impedance of dairy products with different fat content and from multiple manufacturers. During the experiment, we measured the impedance and capacitance of the samples, and the obtained data became available on a PC for further analysis. The aim was to study the electrical properties of dairy products and their dependence on the composition and manufacturer. The obtained results represent valuable information for dairy product production and quality control. It is possible to use them to optimise production processes, ensure stable product quality, and improve consumer characteristics of dairy products. The obtained data contribute to a deeper understanding of the relationship between the impedance signal and the composition of dairy products, which can lead to the development of new methods of analysis and evaluation of the quality of food products. In addition, these studies have implications for food science and nutrition.\u0000Keywords: dairy products, milk quality, impedancemetry, electrical measurements, hardware and software complex.","PeriodicalId":121805,"journal":{"name":"Municipal economy of cities","volume":"27 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140738909","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}

The final report of the World Fire Statistics Centre in 2023 shows that an average of 3.7 million fires occurred annually between 1993 and 2021. The fire resistance of building structures has paramount importance and influence on the development and spread of fires in buildings and structures, which needs consideration at the design stage. Particular attention should be paid to metal structures when used in construction since their fire resistance limit is about 15 minutes, depending on the profile and cross-section of the structure, and this, in turn, limits their use in buildings and structures where the fire resistance class of structures is REI 15. A way to increase the fire resistance class of a steel building structure is its fire protection implemented using dedicated means that protect the steel structure from the effects of high fire temperatures.\u0000The study aims to develop a methodology and determine the heating time of prototypes of steel plates with a fire-retardant coating based on polysiloxane and oxides of aluminium, titanium, and chromium to a critical temperature depending on the coating thickness (0.3, 0.45, 0.6, 0.8 mm) and the thickness of the steel plate (0.3, 0.5, 0.8 cm). To determine the fire protection capacity of the developed fireproof coating, we used the method regulated by clause 7.4 of DSTU-N-P B V.1.1-29:2010 ‘Fireproof treatment of building structures. General requirements and control methods’.\u0000The authors have developed a methodology for conducting experimental studies of the effectiveness of fire protection coatings using an installation for determining the fire protection capacity (effectiveness) of fire protection coatings, the principle of which is to heat the interior of the installation chamber using electric heating elements. The heating time of the prototypes of steel plates with the developed fire protection coating to the critical temperature was determined, depending on the coating thickness and the thickness of the steel plate. We found that the extreme temperature in a steel plate with a thickness of 0.3 cm is reached at 23, 34, and 46 minutes with a coating thickness of 0.3, 0.45, and 0.6 mm, respectively. Experimental studies of steel plates with thicknesses of 0.5 and 0.8 cm have shown that with an increase in plate thickness at the same values of the thickness of the fire protection coating, the time to reach the extreme temperature increases by about 1 minute. At a coating thickness of 0.8 mm, for steel plates with thicknesses of 0.3 and 0.8 cm, the temperature on the unheated surface of the prototype did not reach the extreme value.Given the results obtained, it will be relevant to solve the inverse problem of thermal conductivity to determine the thermal and physical characteristics of the coating based on numerical data from experimental studies.\u0000Keywords: research methodology, standard temperature regime, fire protection c","PeriodicalId":121805,"journal":{"name":"Municipal economy of cities","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140739727","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}

The authors present methods for determining the compressive strength of masonry in existing structures, taking into account reliability theory. We also consider practical solutions for calculating the design strength of masonry, which may help to assess the safety of massive brick walls and pillars that act as core structural elements of existing buildings. Thus, walls and pillars operating in compression are vital elements of stone buildings and require special attention when analysing and assessing their strength. They carry enormous loads and are critical to the stability of the entire structure. There are cases when it may be hard to obtain safe samples for testing masonry mechanical performance, making the analysis of existing masonry structures difficult. However, building codes and methods provide specific methods for determining the strength of existing structures based on reliability theory. These methods assume uniformity of masonry with regularly spaced brick layers. Although such assumptions may simplify the analysis, they can still provide sufficiently accurate results for making decisions about the safety and reliability of the building. It is essential to consider all possible factors and limitations when using these methods to ensure a reliable assessment of the condition of masonry structures.\u0000Stone materials are among the most traditional in various areas of construction production. Buildings with brick load-bearing walls represent the lion’s share of the existing housing development in Ukraine. Ensuring its high-quality operation and the safety of residents during the life cycle of such buildings are priority areas. However, changes occurring in the external environment and the state of regulatory support for construction production require a periodic return to the issues of assessing the load-bearing capacity of both previously erected building structures and those under design. Thus, lately, the territories with previously unusual force impacts on building structures, such as horizontal displacements of the base of the building, have significantly expanded. The reasons for this include seismic activity in certain regions of the country and the results of anthropogenic factors, particularly the areas with unstable soils. We should note that many buildings and structures are subject to external influence due to military operations on a large territory of Ukraine. So, in the event of a hit by warheads or the action of a blast wave, they generate new, non-typical, but dangerous effects on the load-bearing structures of the entire building.\u0000Keywords: reliability theory, reliability assessment, structural safety, stone structures, masonry strength.","PeriodicalId":121805,"journal":{"name":"Municipal economy of cities","volume":"102 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140736030","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}

The mathematical model consists of a system of four analytical dependencies. The first analytical dependence describes determining the area of groundwater intake from the groundwater level, considering the presence of artificial coatings, infiltration, evaporation, and transpiration, as well as the effect of evapotranspiration. The second dependence determines the area of influence of the missile and artillery danger from the type of weapon, the explosive charge, calibre (diameter), and territorial conditions, the key indicators of the content of which in the territory of the critical infrastructure object, which suffered damage, are further determined by expert calculation using natural samples of soils and groundwater. The third dependence determines the impact of harmful (polluting) substances on groundwater in the territory of the critical infrastructure object, which suffered damage, depending on the process of groundwater movement in the area of the emergency, taking into account the hydraulic pressure and water yield coefficient; the process of distribution of chemically dangerous substances in groundwater, taking into account the coefficient of hydrodynamic dispersion and the velocity of groundwater; convective diffusion of chemically hazardous substances, taking into account the kinetics of sorption. The fourth dependency allows us to choose an efficient concept for the organisation of groundwater monitoring on the territory of a critical infrastructure object that suffered damage based on the variation of formalised parameters for solving individual problems. The initial conditions of the mathematical model are related to the presence of chemically dangerous compounds in groundwater at the maximum permissible concentration level.

The object of research in this article is the street and road network of Lviv region, as it is necessary to take into account the regional aspects of traffic and their differences in the country’s regions, given the density of streets and roads, climatic and hydrometeorological conditions, as well as the typology of roads. One of the scientific problems that the study’s results can partially solve is to identify time patterns and dynamics of changes in the number of road accidents in the Lviv region and compare the results with the targets set out in strategic documents in the field of road safety in Ukraine. The article analyses the data on the number of road traffic accidents in the region from 2019 to 2023. At the same time, it carries out the statistical distribution of traffic accidents by the causes of their occurrence. We also account for the time aspect – a breakdown by time of day and days of the week, including the general trend over the past years. We established that the dynamics of the number and severity of road accidents for the period under consideration is negative; however, the patterns of their occurrence persist, which explains the positive statistical result obtained due to quantitative but not qualitative factors affecting traffic safety. The results obtained are of more value from an engineering and scientific point of view, particularly in comparison with traffic accident statistics disseminated on information resources or social media.
