The purpose of the article is to reconstruct the state of the communal economy of the city of Vinnytsia in the historical period of the 20s of the 20th century, in particular, the formation of such components as housing, electricity supply, water supply, sewage, transport, and the organization of urban space. The research methodology is based on the principles of historicism, scientificity, objectivity and systematicity, as well as the application of general scientific (analysis, synthesis, generalization) and special-historical (problematic-chronological, specific-research, historical-comparative, critical) methods. The scientific novelty of the work lies in the fact that, based on the analysis of available documentary and empirical material, the study of a wide range of scientific works, the authors made a comprehensive analysis of the situation of the communal economy of Vinnytsia during the period of the formation of Soviet power, taking into account the specifics of the Podilsk region. Conclusions. In the period of the 1920s, the communal economy throughout Ukraine was in a state of crisis and needed almost complete reconstruction. This was explained not only by the consequences of the revolutionary events of 1917-1921 and the civil war, but also by the Bolshevik policy of "war communism". The problems of improving housing and living conditions for the population were particularly acute in Podillia and, in particular, in Vinnytsia, due to its border location and the conduct of hostilities in the region. The gradual improvement of the city's communal economy began with the introduction of a new economic policy. The main task of the government was to restore the housing stock, economic facilities, city communications and infrastructure. Thanks to the steps towards decommunization, reforms of the management structures of the communal economy, the formation of local budgets, certain positive developments took place in its development: the solution to the "housing crisis" began, favorable conditions for the normal economic operation of buildings began to be created, the reconstruction of electric companies and city transport was carried out, and the communal infrastructure was improved , which contributed to the improvement of the life of the population and the well-being of the city. However, despite these positive trends, there were a number of problems faced by city dwellers - lack of housing, unsanitary conditions of residential premises, incomplete operation of electricity and water supply, insufficient number of communal baths, deficiencies in the organization of fire protection. A number of problems of the improvement of the city originate from the 20s of the 20th century. and is not fully resolved even in modern conditions.

The purpose of the article is an attempt to analyze the results of the activities of domestic researchers of the history of Soviet everyday life (historians, ethnologists, cultural scientists, anthropologists, sociologists, art critics), which were presented at seven all-Ukrainian scientific and theoretical seminars of the series «Everyday Life: Visions and Meanings», held at Vinnytsia State Pedagogical University M. Kotsyubynskyi during 2015-2023. The research methodology is based on a combination of general scientific, special-historical and interdisciplinary methods and tools of socio-cultural analysis. The scientific novelty of the work lies in the fact that it attempts a primary (self) analysis and generalization of the local experience of the problematization of the Soviet past through the lens of everyday life. Conclusion. The initiative of the scientists of the Center for the Study of Everyday History of the Faculty of Vinnytsia Pedagogical University was launched in the context of the beginning of Russian aggression as a response to the request for an in-depth historical-anthropological and socio-cultural study of the (un)completed Soviet past through the visions and meanings of the life world of an ordinary Soviet person. Researchers of leading scientific institutions and higher educational institutions of Ukraine actively responded to the proposal of a scientific and theoretical dialogue between specialists. Some summaries of the journey can be expressed in several theses. First, the choice of topics for each subsequent seminar was not arbitrary. It is determined, on the one hand, by specific public requests and the professional readiness of researchers, and on the other hand, it arose from the specific interdisciplinary work of each previous seminar. Secondly, in Ukraine as  result, a stable core of qualified researchers of the Soviet past from various scientific fields has formed, to which new generations of researchers are interested. Systematic scientific dialogues contributed to the expansion of the subject field of Soviet everyday life, deepened and improved the methodology of its study, significantly for the development of an adequate understanding and interpretation of the Soviet past.

Published: March 2024

The purpose of the article is to study the organization and activities of professional associations of Lviv architects and sculptors, known in the sources as "factory(fabryky)-workshops", during the construction and sculptural decoration of sacred and secular buildings in Lviv and outside its borders in the 1730-s – 1760-s. The methodology of the research is based on the principle of objectivity and historicism, a systematic approach to the study of historical-artistic and socio-economic phenomena in their development and interrelationships. The use of methods of analysis and synthesis, problem-thematic, descriptive and historical-chronological approach made it possible to optimally solve the research task. The scientific novelty of the research involves the description of the activity and internal organization of the factory-workshops of Lviv architects and sculptors during the construction and sculptural decoration of objects of a secular and sacred nature, the importance of the factory-workshops of Lviv artists in obtaining profitable orders, as well as in confrontation with the city corporation. Conclusions. In the professional activity of Lviv architects and sculptors, a significant role was played by the process of organizing the most qualified workers around them into professional associations, which are known in the sources as "factory-workshops". Thanks to them, artists got the opportunity to control most of the orders when creating objects of a secular and sacred nature in the city and beyond. This, in turn, caused a confrontation with the city corporation. Free craftsmen managed to win a number of victories over the corporation on a legal basis thanks to the support of influential patrons, magnate families, representatives of the higher clergy, as well as royal privileges that exempted artists from the claims of the corporation and city authorities.

Published: March 2024

The purpose of the article is to characterize the process of formation and the first steps of the Peasant Land Bank (Selianskyi pozemelnyi bank), to identify and analyze various projects of the organization of a state institution for long-term crediting of the peasantry, which preceded the emergence of the Peasant Land Bank in 1882. Research methodology is based on the fundamental principles of historical research: historicism, systematicity, objectivity in the selection of facts and documents. Scientific novelty of the article lies in the analysis of projects for the formation of the Peasant Land Bank in the Russian Empire in the context of agrarian reforms of the late 19th and early 20th centuries. Organizational and legal aspects and principles of functioning of this bank, its role in the implementation of the government's agrarian policy are studied. The author examines the influence of credit activity of the Peasant Land Bank on the development of agriculture and formation of a class of wealthy peasants in the context of the modernization of agriculture. Conclusions. The establishment of the Peasant Bank, to a certain extent, can be considered as an important step in the direction of public opinion at that time. The concession, which over time was tried to be significantly reduced, was the establishment of numerous restrictions, which indicated the limited effectiveness of the bank's activities. These restrictions included a five million annual transaction limit, a small maximum loan size per person, and the ability to participate in transactions only by voluntary agreement between the seller and the buyer. It was also assumed the need for significant additional payments when purchasing, which were unaffordable for poorer peasants. These restrictions significantly limited the positive influence of the bank. It was noted that the main goal of the bank was realized in a residual way, in particular, due to political reasons and commercial principles that were the basis of its activity. In addition, crediting conditions were considered absurd, as they provided for the same interest rates as in commercial banks. A prospective promise was a change in the focus of the bank's activity to credit support for peasants who intended to farm on the acquired lands, in particular by providing “ameliorative” credit.

The article analyzes the role of Pavlo Skoropadskyi's government in 1918 in the strategic and artistic issue of the development of art, as part of the state-building process in the Ukrainian State of that time, based on archival sources and the scientific work of modern scientists. The research methodology is based on the fundamental principles of historical research: historicism, systematicity, scientificity, objectivity in the selection of facts and documents. The scientific novelty of the article lies in the fact that, for the first time, with the help of archival sources, specific steps in the activities of the Cabinet of Ministers in 1918 regarding the support and development of art, namely theater and cinematography, as one of the components of culture, were revealed, thanks to both financial support and the awareness of representatives of the government of Pavlo Skoropadsky of the national-patriotic orientation regarding the importance of the development of national art as part of the state-building process. Conclusions. In the conditions of the exhausting First World War and the economic devastation in the state, the government of Pavlo Skoropadskyi attached great importance to the development of art, in particular theater and cinematography. The government considered the sphere of theater not only as an important form of cultural expression, but also as one of the directions of state-building in the development of the national interests of the Ukrainian State, in order to ensure the spread of the Ukrainian language and culture among the population of that time. Cinematography in 1918 was at an early stage of development. However, even then the government understood its potential and recognized the importance of cinema not only as an innovative invention, but as a means of mass information and state propaganda to influence the population. At the state level, mechanisms were developed to support the cinematographic industry and the Ukrainian theater of that time, which were constantly financed by Pavlo Skoropadskyi's Council of Ministers, as evidenced by archival documents. The Cabinet of Ministers of that time was well aware that in order to build a full-fledged state, support in the field of national culture is necessary, and that this is one of the elements of the socio-cultural values ​​of a person, which contributes to the formation of the unity of the nation and lays the foundation of an educated and tolerant society in the future.

The purpose of the article is to analyze the activities of the national organizations of Kharkiv region in the struggle for independent Ukraine both against the USSR and against Germany during the Second World War and to clarify their role in preventing the export of the Ukrainian Ostarbaiters to Germany. The research methodology is based on the use of the historiographical analysis method, the historical-systemic and problem-chronological method, the method of critical analysis. The scientific novelty of the research consists in the fact that for the first time the systematization and analysis of materials dedicated to the activities of the nationalist movement in the Kharkiv region was carried out in order to determine the role of national organizations in helping ostarbaiters. Conclusions. A special role in the development of the nationalist movement in the Kharkiv region during the World War ІІ belongs to the Derivative groups of the Organization of Ukrainian Nationalists. Kharkiv residents revived the activities of "Prosvita" and organized the "Kharkov Civic Committee". Their main task was the restoration of the independence of the Ukrainian state and the recognition of its legitimacy by the Soviet and German authorities. In Kharkiv, in order to achieve a similar goal, representatives of nationalist organizations tried to occupy positions in German authorities, especially in particular Kharkiv residents. Among the large number of lands captured by Germany, it was Ukraine that became the source of replenishing the labor force for the benefit of the Third Reich. Nationalist organizations contributed to preventing the deportation of the population of Kharkiv region to work in Germany. The activities in this direction of V. Dolenka and M. Gorban, who tried to solve it through their influence on the members of the "Kharkov Public Committee" and "Prosvita", who worked in the bodies of the occupying German authorities, should be highlighted.

The purpose of the research is to analyze the measures of the Soviet authorities to overcome child homelessness and neglect, the functioning of orphanages on the example of the Zhytomyr region in the period from the mid-1950s to the first half of the 1960s. The methodological basis of the research is built on the analysis and synthesis, historical-statistical, and historical-comparative methods as well as the use of the principles of scientificity, objectivity and historicism in the analysis of the Soviet authorities’ policy of overcoming those negative phenomena among minors. The scientific novelty of the work is presented by a comprehensive study of the state policy on overcoming child homelessness and neglect in the Zhytomyr region of the Ukrainian SSR during the mentioned period with using new archival sources. Conclusions. Homelessness and neglect of the minors were urgent problems in the period from the mid-1950s to the first half of the 1960s both in the Zhytomyr region and Ukraine as a whole. They were gradually resolved, the authorities took appropriate measures. From the side of the relevant executive authorities, there was often a formal approach to solving the problems of child homelessness and neglect. It should be noted that this problem was organically connected with the command-administrative and bureaucratic system of the Soviet government, for which reporting and certain indicators were important but the practical solution of the children's problems was delayed. The relevant authorities’ inspections of the ways the orphanages worked revealed the financial shortcomings, problems in material support and educating which had a negative impact on the pupils in those institutions. A serious problem is proved to be the absence or lack of the parents’ attention to the upbringing of their children at that time. Moreover, the enterprises and institutions, that were supposed to contribute to the cultural and educational development of their workers’ and employees’ children, did not do that.  The issues of organizing leisure time for the minors by the children and school institutions was relevant, as the problem of neglect and committing the crime by the uncontrolled minors depended directly on those solutions. The methodical assistance in working with children provided by regional libraries to village ones was insufficient and very often it was not actually carried out. Cultural centers and village clubs did not conduct educating work to children. Prospects for further research relate to the problems of neglect and juvenile delinquency in the Zhytomyr region in the 1980s.
Образ людини і світу в сучасній музиці: антропологічні виміри творчості українських композиторів у соціокультурному континуумі

Based on the principles of historical and systemic approaches and methods of hermeneutical and philosophical anthropological analysis, the author of the article aims to identify the peculiarities of the content of the world model and the model of a human in Ukrainian music of the last third of the twentieth and twenty-first centuries in comparison with Western European music and to characterize the composer's vision of the world order in the time of open Russian aggression in Ukraine. The research methodology is based on systemic and historical approaches that allow us to consider a single musical text as a subsystem of a higher-order system, taking into account its socio-cultural context. The scientific novelty of the study is to identify the specifics of the artistic outlook of Ukrainian artists of the last third of the twentieth and twenty-first centuries, which is the result of studying their work in the anthropological dimension. Conclusions. The anthropological essence of the music of contemporary Ukrainian composers lies in a certain non-contradictory polarity, when an ironic and fragmentary worldview is organically combined with religious search; awareness of chaos and apocalyptic culture – with an attempt to find support in religion in its various variants. That is why the hero in contemporary music has a dual essence: he is both a marginalized person and at the same time a person with a strong spiritual foundation. This polarity is caused by the crisis mentality of the modern post-totalitarian society.  The specificity of the content of Ukrainian wartime music is that in the first year of the war, composers sought to directly embody the reaction to the atrocities they saw, which manifested itself in the increased expressiveness of the expression, and in 2023 we can already observe attempts to philosophically comprehend the topic of the confrontation between good and evil, the formation of a systemic view of the world in times of war, in which there is a place for different feelings and different areas of private life.
Modeling surface structure of tribotechnical materials
Authors: Drach I. , Dykha M. , Babak O. , Kovtun O.
Published: March 2024

Modern tribology makes it possible to correctly calculate, diagnose, predict and select appropriate materials for friction pairs, to determine the optimal mode of operation of the tribo-joint. The main parameter for solving friction problems and other problems of tribology is the topography of the surface. The main purpose of the models in these tasks is to display the tribological properties of engineering surfaces. In the framework of the classical approach, the topography of the surface is studied on the basis of its images from the point of view of functional and statistical characteristics: the evaluation of the functional characteristics is based on the maximum roughness along the height and the average roughness along the center line, and the statistical characteristics are estimated using the power spectrum or the autocorrelation function. However, these characteristics are not only surface properties. They depend on the resolution of the device for measuring the surface geometry and the length of the scan. However, the degree of complexity of a surface shape can be represented by a parameter called the fractal dimension: a higher degree of complexity has a larger value of this parameter. Fractal dimensionality is a characteristic of surface relief and makes it possible to explain tribological phenomena without the influence of resolution. This article provides an overview of mathematical approaches to the description of the relief of engineering surfaces, in particular statistical, stochastic and topological modeling, their limitations, advantages and disadvantages. The implementation of the principles of the theory of fractal structures is discussed, which makes it possible to introduce the degree of imbalance of the tribological system into the analysis of structure formation in the surface and near-surface layers of materials and to describe the development of friction and wear processes. This is the basis for controlling the structure of the surface layers of materials with given properties. The concept of fractals, used for the quantitative description of the dissipative structure of the tribojunction zone, makes it possible to establish a connection between its fractal dimension and mechanical properties, as well as critical states of deformation of metals and alloys. The course of research and stages of fractal modeling, the classification of methods of fractal analysis of the structure of engineering contact surfaces are considered. A critical analysis of modern models based on the energy-spectral density function, which are quite similar to fractal models, is presented. Readers are expected to gain an overview of research developments in existing modeling methods and directions for future research in the field of tribology

Published: March 2024

The technologies of continuous strengthening of technological surfaces have practically exhausted their capabilities, which calls for the creation of fundamentally new approaches. The application of the principles of discrete-oriented strengthening of tribosystems has wide prospects for improving existing methods of strengthening due to the selection of modes and control of the geometric structure of the surface layer. The essence of the discrete-oriented strengthening method is the application of combined electromechanical processing and electrocontact cementation of cylindrical surfaces. The purpose of the work is to determine the parameters of discrete processing of cylindrical steel parts that are optimal according to the surface hardness criterion. Using the Statistica program, a factorial experiment was implemented according to the Box-Behnken plan, and the results of dispersion and regression analysis of the influence of processing parameters on microhardness were obtained. It was established that the following optimal parameters of DOZ processing are necessary to achieve the maximum values of microhardness (5950 MPa): current strength-500A, force-350 N, contact time-0.3 s.

The paper uses the principles of the system approach to establish the relationship between wear of individual surfaces on the example of a gear drive of the GP type pump. The hierarchical structure of the part is considered, its individual functional parts are classified as subsystems, and the working surfaces are classified as system elements. A systematic approach to the study of part wear condition included, in addition to identifying the relationships between the wear of individual elements of the part, the creation of a mathematical statistical model of the worn part as a whole, as a system. The main types of wear of the gear working surfaces were determined. The laws of wear distribution of gear working surfaces and their main numerical characteristics were found. The established relationship between the wear of individual gear elements has become the basis for the system quality of the technical system "gear drive of the GP pump" in relation to the wear of its elements. A mathematical statistical wear model was obtained in the form of linear regression equations system of gear elements wear dependence on their outer diameter wear. This makes it possible, using the principles of a systematic approach based on the data of a single defect – gear wear along the outer diameter, to create a complete statistical image of the worn part, i.e., to determine the wear of other elements of the drive gear. The results obtained allow us to reasonably approach the issue of choosing a method for restoring parts and forming routes for the technological process of restoring a part.

Wear and tear limits the possibilities and shortens the operational life of modern technical systems. Therefore, the importance and necessity of consideration of issues aimed at reducing frictional forces and increasing wear resistance cannot be doubted. The paper summarizes the theoretical and applied results of triboresistance studies of detonation coatings of the Nb-Zr-V-Si-C-MgC2 system under conditions of constant loading in the field of sliding velocities. It has been established that the ratio of the quality of the components that make up the surface modified structures changes. It is noted that at the initial test speeds the presence of lower metal carbides that are part of the coating dominates, with an increase in speed under the current load due to solid-phase and diffusion processes, higher ones are formed in the graphite matrix carbides with enhanced thermodynamic properties.

The article elucidates the essence of the mechanisms of electronic and phonon friction in the coupling of samples (parts) using the methods of solid state physics.

It is shown that in the triboconjugation of samples made of metallic materials, the flow of fluctuation-electromagnetic and electron-phonon processes should be distinguished. Fluctuation-electromagnetic interactions have long-range effects, and electron-phonon interactions have short-range effects. Based on Lifshitz's fluctuation-electromagnetic theory, the force of friction in moving couplings of metal samples is substantiated, taking into account the frequency ratio in the atomic absorption spectrum and the plasma frequency. A formula for estimating the friction force was obtained, taking into account the dielectric function and the Clausius-Mossotti formula.

The electronic friction force was estimated using the "jelly" model and the generation of electron-hole pairs in the quantum perturbation theory of solid-state physics.

The mechanism of electronic friction was discovered based on the phenomenological theory of braking losses of slow ions in solids. The scheme of the model of the electronic friction mechanism is close to the Persson model, which connects the braking force with the electron scattering process. A refined formula for estimating the electronic friction force is proposed.

The strength of phonon friction is justified on the basis of structural effects that can be induced by the mechanism of breaking adhesive bonds, and perturbation theory. A formula was obtained for estimating the force of phonon friction, taking into account the frequency of phonons, the inverse decay time and the function of the two-dimensional Fourier image of the force of interaction between the atoms of the conjugated surface of the triboelement.

Cases of static and dynamic phonon friction are considered.

Electronic and phonon frictional forces are considered at the nanolevel. The Debye low-temperature approximation and refinement of the expressions for estimating the electronic and phonon friction forces are given, taking into account the type of interatomic potential

Benedict XVI distinguishes between munus and potestas as useful concepts in understanding the authority of the diocesan bishop. While the concept of potestas goes back to the Roman law of jurisdiction, the munus terminology is relatively new, since it stems from the theology of Dietrich von Hildebrand, who distinguished between munus sanctificandi, munus docendi and munus regendi. As highlighted by Pope Benedict XVI, thanks to the orders of the episcopate, the bishop shares in the munus, which is not equal to potestas; therefore only the diocesan bishop, who persists not only in communio but also in communio hierarchica with the Catholic Church, enjoys legislative power, which he exercises directly; however, his sacred power of the sacraments can be exercised through sacred ministers, and in the case of the executive power also through the lay faithful, by virtue of missio canonica. The bishop implements that by administering Mass intentions and offerings donated in the diocese.
