Authors:   Odesa National University of Economics, Kravets Daria
Published: November 2023

The article analyzes profitability indicators and the financial condition of food industry enterprises. The assessment of the most influential coefficients characterizing the state, dynamics and efficiency of the use of financial assets was carried out. The influence of the management of financial assets on the overall efficiency of the enterprise, which are the most liquid part of the company's resources, is determined. Recommendations were developed to prevent possible economic problems of the enterprise, in particular, it was suggested that the top management personnel implement prompt and timely response to changes in the external and internal environment of the enterprise. The food industry is one of the most important and promising for the further development of industries in Ukraine, the effective activity of which can not only significantly increase the country's budget, but also create internal food security and ensure social aspects: jobs and stability of staff income, production of quality food products by enterprises state control over its safety and quality, which will lead to a decrease in the volume of deliveries of low-quality foreign products to the country and strengthening of domestic producers in the domestic market, will create conditions for healthy competition in the industry in which the sale of own food products is possible under the condition of production of the best possible, natural, original and tasty product, will increase the socio-economic aspects of the state and development of the state. In order to analyze the influence of indicators of the efficiency of the use of financial assets on the profitability of assets, it is proposed to use empirical-inductive systems, which are an important methodology in scientific research. One of the elements of such a system is the DuPont model. To identify the influence of financial assets on the level of profitability of assets, the improvement of the DuPont model is proposed, namely, it is disaggregated by introducing two factors: the specific weight of financial assets in the total amount of assets of the enterprise and the efficiency of their use. The effectiveness of the management of the company's activities is a multifactorial system that includes the analysis of all components and resources. Such analysis combines empirical data and inductive thinking to formulate general patterns and hypotheses. Therefore, one of the main tasks of improving the efficiency of enterprises is the need for rational management of financial assets.

Authors:   Classical Private University, Atamanchuk Yurii
Published: November 2023

The value of information in modern society is difficult to overestimate. In the period of the war with russia on the territory of Ukraine, the informatization of society is very fast, and in the field of education, the flow of a wide variety of information has increased, the means and methods of its transmission, processing and storage are being improved. Due to the development of processes of informatization of the education system of Ukraine, educators are involved in a whole system of information relations, and their activities without obtaining and using relevant information are practically impossible. Information provision of education, as the professional activity of a teacher, is an urgent need and is becoming more and more relevant. Education reform is impossible without improving the procedure for its completion, as well as information support. The rapid expansion of the scientific space of the Internet contributed to the growing popularity and importance of scientific Internet publications. Observations have shown that most scientists search for information on the Internet by keywords. This method uses too many sources, most of which do not meet the needs of the teacher. Placing electronic versions of scientific publications, textbooks, manuals, dissertations, and encyclopedic materials on the Internet created opportunities for wide use of these resources in educational activities. The analysis of the topics of publications in scientific-metric databases allows us to identify the fastest-growing industries, the distant prospects of technological breakthroughs, which are very relevant in this difficult time for Ukraine. Improving the teacher’s ability to use information and communication tools in the work should take place in a specially organized activity, in which each of the components should find development: personal, scientific-theoretical, practical.

Authors:   Lesya Ukrainka Volyn National University, Ierko Iryna
Published: November 2023

The concept of tourism industry and the competitive potential of tourism industry subjects are analyzed. The conducted research made it possible to combine the opinions of scientists into three approaches: infrastructural, consumer and socio-economic. The infrastructural approach is interpreted as a set of various infrastructural objects that provide service and provide quality tourist services to tourists. The consumer approach is aimed at consumption of tourist products and maximum satisfaction of consumer needs in quality tourist services. The socio-economic approach considers the tourism industry from the standpoint of obtaining economic and social effects from the provision of tourist services and a positive impact on the development of the national economy. It was established that the main features of the concept of "tourist industry" are: the presence of infrastructural tourist facilities, the consumer value of the tourist product/service; synergistic effect (socio-economic effect) in the process of providing/producing a tourist service/product. As a result of the research, three approaches to the content of the concept of "competitive potential of the tourism industry subjects" were distinguished, namely: potential ability (the ability of a tourist destination to produce a quality tourist product/service, to effectively use available recreational and other resources to ensure the competitiveness of the subject of the tourist industry), competitive advantages (current trends in the development of the tourism industry should be analyzed from the standpoint of existing competitive advantages, as well as forecast future scenarios of its development taking into account potential threats and dangers regarding the formation of such advantages in the field of tourism industry), tourist attractiveness (the presence of favorable natural resources and natural conditions, a favorable ecological situation, historical, cultural and architectural monuments, developed tourist infrastructure, which collectively attract tourists). The overview of concepts allows us to single out the criteria for the competitive potential of tourism industry entities: competitive advantages and sustainable and safe development of the tourism industry.

Authors:   State Biotechnological University, Kukhtin Yurii
Published: November 2023

The article is devoted to the study of the ecological state of land in Ukraine and the Kharkiv region, as well as the issue of land resource management in the OTG for the purpose of land protection. Research methods: analysis and synthesis, graphic (when studying the state of land resources, organic production), system-analytical, inductive (for summarizing research results, forming conclusions and recommendations). The main problems of the ecological condition of land resources in Ukraine and in the Kharkiv region were identified and investigated. It was established that the level of fertility of the region is sufficient for agricultural production, but there are a number of negative factors: mining of a large part of the territory, soil degradation, exogenous geological processes. A significant negative impact of military operations and minefields on the state of the environment and, in particular, on land resources in the occupied part of the Kharkiv region was revealed. It may take decades to eliminate the adverse factors caused by war. The development of the production of organic products in Ukraine was analyzed. The dynamics of the export of organic products from Ukraine to the EU countries was studied, as well as the volume of sales on the domestic market was analyzed. On the basis of the conducted research, it is proposed to stimulate organic production in UTC for the development of the region and filling of the local budget. The management of land resources from the point of view of environmental problems in the context of decentralization of power was studied using the example of the Zmiiv urban territorial community. The plan of environmental measures of the governing body of the Zmiiv city territorial community was studied. A number of preventive measures are proposed for further improvement of the ecological condition of land resources. One way to improve the environmental situation in the Kharkiv region is to involve representatives of local businesses and volunteers in environmental and environmental protection measures. The organization of such events should be carried out by the governing body of the united territorial community.

Viewpoints and Perspectives of Batak Migrants on Dalihan Na Tolu: The Exposition Revition
Authors: Iskandarsyah Siregar
Published: November 2023

The philosophy of life of the Batak tribe, namely Dalihan Na Tolu, is believed to be able to maintain order in the social life of the Batak community and family. Dalihan Na Tolu determines the form of greeting, position and attitude that applies in traditional ceremonies and daily life. Amid the rapid current flow of globalization, there are fears that the local wisdom of traditional culture, including the philosophy of life that has been believed for a long time, will erode, especially among families living in metropolitan cities whose infiltration or infiltration. The mixing of cultures is very dynamic and robust. This research was conducted to reveal how the Batak community in the metropolitan city perceives the values of Dalihan Na Tolu. The study shows that among the Batak settlers in Jakarta, the value of Dalihan Na Tolu is still highly understood, accepted, and appreciated, even though the breadth of knowledge and depth of meaning is different. Some factors that influence these differences include sub-ethnic origin, profession, the intensity of the Batak community association, and position in the family. The study's results also concluded that the childhood environment had a significant effect on the internalization of cultural values.

Authors: Коptovets O , Shyrin L , Yavorska O , Herasymenko A
Published: November 2023

Purpose.The task of researching modes of established frictional oscillations of the braking mechanism is to find a solution to the initial dynamic problem with friction that satisfies the periodicity conditions. At the same time, the period of motion of the dynamic system is not known in advance. This dynamic system is described by a non-linear dissipative non-autonomous system of differential equations. The methods. The developed technique of spectral analysis of the braking mechanism's oscillations is based on the assumption that its movements are periodic. If deterministic chaos occurs in the analyzed dynamic system, then the autocorrelation function of the time series of movements must have a finite carrier, that is, vanish outside a finite time interval. Findings. In the paper, the method of computational experiment is used to identify and study the characteristics of oscillatory processes in brake mechanisms. At the first stage of the computational experiment, a numerical solution of the considered dynamic problem with friction is carried out using a computational algorithm. As a result, the time series of block movements are calculated. At the second stage of the computational experiment, the obtained time series are studied. The originality. The paper uses phase diagrams in the "displacement-velocity" variables to analyze the process of establishing the oscillations of the brake mechanism and visual detection of attractors. When studying the dependence of amplitudes of displacements, velocities and accelerations of the dynamic system under consideration on changes in its parameters, the method of continuation by parameter was used with a stepwise change in the parameters of the system. Practical implementation. The developed mathematical model of vibrations of the braking mechanism and the computational algorithm for its numerical study are implemented in the form of a computer program for personal computers in the FORTRAN algorithmic language. Almost all available commercial compilers can be used to compile the program, including Compaq Visual Fortran 6.6 and Intel Visual Fortran 10, as well as non-commercial compilers distributed under the GNU license.

Published: November 2023

Purpose. Establishment of dependences for stress-strain state parameters in a rubber-cable rope with cables of different tensile rigidity and cable breakage. Research methodology. Construction and development of an algorithm for solving a model of a stress-strain state of a rubber-cable rope with ropes of different tensile rigidity and breakage of one cable by using the methods of mechanics of layered composite materials with soft and hard layers. Findings. Analytical expressions are constructed, which allow determining the main stress-strain state indicators in a rope with an odd number of cables, while the middle cable is damaged, and tensile rigidity of the middle cable is half the tensile rigidity of the other cables. Analytical dependencies are established for determining the extreme angles of rubber shear between the cables, what allows determining the most dangerous tension states of a rope with a damaged cable, which has a different rigidity from the other cables. The level of reliability of the developed algorithm for solving the model of a stress-strain state of a rubber-cable rope with cables of different rigidity is confirmed by determining the maximum tensile forces of a rope made of three cables, in which the middle cable has a tensile rigidity half that of the other two. The force distribution coefficients between cables adjacent to the damaged one are equal to 1.25 per unit load on each cable, which corresponds to the only possible case of force distribution between parallel elements under the presented conditions. Scientific novelty. The character of influence of different rigidity and damage of the reinforcing cables on the main parameters of stress-strain state in a rubber-cable rope are established. Practical significance. An algorithm for determining the stress-strain state indicators of a rubber-cable rope, which has an odd number of reinforcing cables, its middle cable is damaged, and the tensile rigidity of the middle cable is different (lower) than the rigidity of the other cables, is developed. This makes it possible to increase the operational safety of rubber-cable ropes in hoisting and transporting machines, in particular when operating at significant lifting heights, and also contributes to justifying the use of a rope design as a stay rope in capital structures.

Published: November 2023

Purpose. Increasing the efficiency of the building's energy system by taking into account the interrelationship of energy sources, thermal protection, indicators of thermal comfort and microclimate parameters of the premises. Taking into account the changes in the requirements of the European Union for indoor temperature and modern economic challenges, the main goal is to develop a system for automatic control of thermal comfort in a given temperature range with minimization of energy costs. Today, there are already many installed heating and cooling air systems. Based on this, the development of a universal device for maintaining thermal comfort in the room is promising. The methods. To conduct an analysis of the developed approaches to increase the efficiency of the energy system of the building in terms of thermal comfort, to determine the features and possibilities of the energy analysis of heat and taking into account the limitations of human thermal comfort. Findings. The proposed structure of the thermal comfort regulator will make it possible to develop a universal regulator that can be used in heating and air cooling systems, or in combined systems. Improving the quality of indoor temperature control can be achieved by directly managing thermal comfort based on the predicted average PMV score and the predicted percentage of dissatisfied PDD. The originality. Typical approaches to managing indoor comfort based on temperature do not take into account radiation, humidity, air speed, clothing and user load, which leads to both the creation of uncomfortable conditions and excessive use of energy resources. For the first time, in accordance with DSTU B EN ISO 7730:2011, the structure of the thermal comfort control system was proposed, its input and output parameters and ways of obtaining non-measurable parameters were defined. The control system based on the predicted average PMV score and the predicted percentage of dissatisfied PDD determines the level of thermal comfort in the room and reduces the number of dissatisfied users. Management based on the predicted average PMV score ensures a reduction in the use of energy resources while maintaining the minimum acceptable thermal comfort indicators. Practical implementation. The resulting structure can be used in the development of new thermal comfort control systems. Taking into account the presence of a large number of already existing heating and air cooling systems, it is proposed to use thermal comfort regulators to improve the quality of their functioning. The proposed approach through the use of the thermal comfort model will make it possible to determine the heating needs under different comfort conditions, reduce the energy consumption of the building without harming human health, and assess the possibility of increasing energy efficiency by changing the comfort conditions, thermal protection parameters and the microclimate of the premises.

Purpose. The energy characteristics of asynchronous electric drives in steady-state operation are functions of three variables: the angular speed rotation of the rotor, the module of the vector flux coupling of the rotor and the moment load. The moment of load is an external disturbing influence, effective methods of its measurement are not available. Therefore, the purpose of this paper is to mathematically describe the observer of the state variables of the active power channel and the load moment on the shaft of an asynchronous electric drive with vector control. Methodology. To achieve the purpose of the work, the method of synthesis modal observers is applied using the field-oriented model of the asynchronous machine with the decomposition of its equations and taking into account the nonlinearities of cross-connections between the control channels. Results. As part of the relay-vector control system, a modal observer of the load moment is synthesized, the information from the output of which can be used to build algorithms for extreme control of an asynchronous electric drive. The asymptotic stability is proved by the method of mathematical modeling and is sufficient the accuracy of the observer of the load moment at different distributions of the roots its characteristic equation. Scientific novelty. Thepaper solves the actual scientific problem of establishing the regularities of the structural-algorithmic synthesis and tuning of the modal observer of the moment of load on the shaft of an asynchronous electric drive. Identification of the moment load on the shaft of an electric machine will allow to improve the quality indicators of extreme control systems of asynchronous electric drives. Practical significance. The obtained equations of the observer determine the load moment identification algorithm, the information about which can be used in two-channel vector control systems for asynchronous electric drives to build an external extreme control circuit, which improves the energy performance of the asynchronous machine. First of all, we are talking about minimizing the loss of active power or the consumption of reactive power an asynchronous machine when the load moment on its shaft changes.

Although human rights in general and the right to a healthy life are very important in Turkey, as in the whole world, they can sometimes be violated due to economic, cultural, bureaucratic or legal reasons. The main problem of this research is that the use of advanced technology in health leads to grievances in some cases as well as the benefits it provides. In this study, it is aimed to reveal the effects of perceiving the data collected in health from time to time as a risk. Qualitative data collected by making oral history on the basis of narrative revealed that individuals stay away from health services because of the concern that their privacy decreases as digitalization in health increases. In order to reduce the risk of risking the health of especially disadvantaged groups, some suggestions have been made based on interdisciplinary studies, especially providing anonymity in online health services.
