Walker Empowering Women in Meridian
Authors: Parajuli Raju
Published: March 2023

With the picture of personal struggle to overcome the patriarchal society, Alice Walker has concentrated on the empowerment of female values for the establishment and preservation of social and individual female identity in Meridian. Portrayed as a poor, uneducated, and a black girl, Meridian faces social and culturally harsh treatment and black males have behaved her as a toy resulting in double patriarchy. Her attachment with the Civil Rights Movement has brought a transformation and realization within her, which has ultimately enabled her to exist and revolt against male hegemony. Following the feminism as its theoretical tool, this research examines on how a neglected, uneducated poor black girl Meridian transfers herself into an independent woman having her own identity with representative character of an empowered woman. This article tries to examine how Walker has empowered females in the novel, Meridian.
Public Expenditure on Transportation Infrastructure and Growth: Evidence from Nepal
Authors: Khanal Santosh , Karki Krishna Bahadur , Chhetri Santosh
Published: March 2023

The speedy growth in public investment in various sectors was assumed after decades of conflict and an unstable political situation. With the declaration of the Federal Republic, Nepal is going to embark on accelerated economic growth. This has somewhat caused concerns among policymakers of its implication for economic growth. And the government investment in transportation infrastructure is one of the core strategies, called the ‘infrastructure of infrastructures’. The main aim of this study is, therefore, to explain the relationship between economic growth and public expenditure in the transportation sector in Nepal. Primarily, this study has focused on the distinction of expenditures in the five-year development plans in three systems (Panchayat, Democratic, and Republic). This study used time series data collected between 1975 and 2016. The statistical and econometric tools have been used for the study. The result shows that the trend of government investment on public expenditure has increased in the Republic system. This study reveals that the variables are stationary on the first difference. The obtained regression model is satisfactory by diagnostic tests (errors are normally distributed, no serial correlation and homoscedastic). The data explain the positive and significant influence of Transportation Capital Expenditure on Gross Domestic Product, and, hence, it is contributing to economic growth. Furthermore, the results show short-run unidirectional causation from Transportation Capital Expenditure to Gross Domestic Product.

Rola metafory w mediacji – konceptualizacje teorii sprawiedliwości naprawczej
Authors: Leder Wojciech
Published: March 2023

Niniejsze opracowanie ma być szkicem, próbą nowego spojrzenia na filozofię karania przez pryzmat metafor sprawiedliwości naprawczej. Metafora kognitywna – poprzez mechanizm kategoryzacji i tworzenia odesłań między abstrakcyjnymi pojęciami i konkretnym doświadczeniem – pozwala spojrzeć na założenia różnych teorii sprawiedliwości jako na sposoby rozumowania, a nie tylko zbiory twierdzeń. Do najważniejszych metafor sprawiedliwości należy zaliczyć „sprawiedliwość jako równość”, a także odpowiedniki metafor moralności George’a Lakoffa: „surowego ojca” i „opiekuńczego rodzica”, które częściowo korespondują z koncepcjami odpowiednio – sprawiedliwości retrybutywnej i naprawczej. W końcu same mediacje są miejscem, w którym poprzez świadomie stosowane tzw. metafory transformatywne mediator oddziałuje na rozumowanie stron, wpływając na ich wizję konfliktu.
Resistance to leaf rust in cultivars and wheat lines of Paraguay
Authors: Scholz Ruth , Pereyra Silvia , Silva Paula , Germán Silvia
Published: March 2023

Leaf rust (LR) of bread wheat (Triticum aestvium L.), caused by the fungus Puccinia triticina Eriks, is one of the most important diseases in Paraguay, the Southern Cone and worldwide. The economic importance of the disease is clear considering that two or more fungicide applications are necessary to control it in susceptible cultivars. The best strategy for the management of this disease is through genetic resistance. This research was conducted in Uruguay aiming to postulate the LR resistance genes present in 102 lines and wheat cultivars from Paraguay, and to study their field resistance. The presence of 18 major resistance genes expressed at the seedling stage (Lr1, Lr2, Lr3a, Lr3bg, Lr3ka, Lr9, Lr10, Lr11, Lr16, Lr17, Lr23, Lr24, Lr26, Lr27+Lr31, Lr28, Lr30, Lr42) was postulated based on the reaction to different races of the pathogen. The adult plant resistance gene Lr34 was confirmed in 26% of the materials, based on the molecular marker csLV34. This study also allowed differentiating materials with field resistance that can be explained by the seedling resistance and those with adult plant resistance. Knowledge of the resistance genes present in the germplasm of breeding programs is of paramount importance to establish strategies in order to achieve effective and long-lasting resistance based mainly on the combination of race-non-specific minor genes.
Igniting an Intersectional Shift in Public Policy Research (and Training)
Authors: Tedds Lindsay M.
Published: March 2023

Tout au long des années 2010, l’une des principales préoccupations en ce qui concerne les politiques publiques et les débats sur celles-ci était la compréhension des sources d’inégalité, de même que le rôle du gouvernement dans la lutte contre l’inégalité des revenus. Bien que des progrès aient été réalisés, d’importantes lacunes subsistent en matière d’inégalité – lacunes qui vont bien au-delà de l’inégalité des revenus et que la pandémie de COVID-19 a mises en évidence. L’expérience de la pandémie nous rappelle que les individus qui forment la société vivent des expériences distinctes et que l’attention à l’inégalité et à la diversité doit s’intégrer étroitement à des cadres stratégiques actualisés. Après la COVID-19, alors que les gouvernements s’engagent à ce que la relance soit équitable et dans le contexte d’un désir généralisé pour une société plus juste, une approche inclusive de l’analyse des politiques est nécessaire afin de remédier aux défaillances de longue date de l’économie et de la société. Les cadres stratégiques actualisés doivent être plus représentatifs des expériences et des luttes des populations marginalisées et sous-représentées, et leur accorder plus d’attention. L’intersectionnalité est un outil analytique ancré dans le paradigme de la justice sociale qui met au jour les liens entre les notions d’identité et les systèmes de pouvoir à travers lesquels elles se déploient. L’intersectionnalité tient compte de la façon dont nos identités se forment : à l’intersection de divers construits sociaux, tels que la race, la capacité, la classe et le genre, et dans des contextes et des structures de pouvoir plus vastes, comme le marché du travail et les institutions gouvernementales. L’intégration complète de l’intersectionnalité à l’analyse des politiques permettrait de mettre en place une structure d’analyse des politiques qui ferait avancer les programmes politiques centrés sur la diversité, l’inclusion et l’équité.

Published: March 2023

This research paper examines the usage of combining the meta-heuristic approaches for solving critical real-world optimization problems due to the hard and soft constraints. For the last few decades, developing an optimal solution for these problems were considered as a difficult task, and manual timetabling required an excessive amount of effort and time to deliver the quality results. This paper's objective is to address several approaches and develop a generic solution for solving a wide range of timetabling and scheduling problems. Many techniques and benchmark instances have been reviewed and presented to find a feasible solution in the literature section. This paper also investigates the performance based on the combination of meta-heuristic approaches to solve the problem and introduce the algorithm to allocate time slots to several resources according to their constraints satisfaction and violations. However, this algorithm may consider as a comprehensive benchmark instance and significant improvement for future researchers. Furthermore, the computational and experimental results of the algorithm determine the feasibility, effectiveness, robustness, and optimality of the proposed approach.

The article analyzes the content and features of the study of the educational discipline "Pedagogy of creativity", the purpose of which is the formation of students' theoretical knowledge, practical abilities, skills and competencies that ensure the formation of a creative personality, the development and self-development of creative abilities in the process of education and training, the creation of psychological and pedagogical conditions for the manifestation of the individual's creativity in socially useful and individually significant types of life activities. The objectives of the discipline are revealed, which consists in students' assimilation of key points and problems of modern pedagogy of creativity, learning of laws and regularities of pedagogy of creativity as a field of pedagogical knowledge about the creative development of the individual, acquiring the ability to diagnose creativity, analyze the results obtained, and create conditions for the creative self-development of the teacher's personality. The content of two sections of the educational discipline is specified: "General foundations of creativity pedagogy" and "Formation and development of creative personality".
Attention is focused on the fact that the pedagogy of creativity is not only a humanitarian discipline, but also a personal one. Therefore, when forming the content and methods of its study, it is important to move away from established stereotypes and templates, declarativeness, excessive schematism and descriptiveness. Their priority should not be the content of as much information as possible, but the opportunity to motivate, develop pedagogical abilities, intelligence and experience of creative activity, which is a leading component of education. The peculiarity of the discipline is the filling of the topics defined by the program with vital content, orientation towards its qualitative characteristics, content that would excite, encourage reflection, introspection. Therefore, educational classes in this discipline are not only a form of organization of education, but also a way of helping the students in their personal and professional development.

The article reveals the organizational and pedagogical foundations of the professional growth of a primary school teacher in the process of his professional activity. Attention is focused on the versatility of the profession of a primary school teacher, which causes high requirements for his professional qualifications. The teacher, in order to maintain a high level of professionalism, needs to constantly improve himself, to grow professionally. It is emphasized that the high level of academic achievements of the future teacher while studying at an educational institution is not always the guarantor of his success in professional activities. The educational and professional qualifications of a pedagogical worker are not identical, which requires further work on themselves.
It is noted that professional growth throughout life consists of three main stages: formal education; the beginning of professional activity as the entry of an employee into the profession; continuous professional development. The creative professional activity of the teacher is activated in the process of certification, internship, certification. The directions of professional growth of primary school teachers are determined. The role of the centers of professional development of pedagogical workers, their tasks, functions, features of activities to create an educational environment is shown. Examples of activation of educational institutions in the direction of professional development of pedagogical workers are given: introduction of a pedagogical-centric model of advanced training due to the practice-oriented component of its implementation at the Institute of Postgraduate Borys Grinchenko Kyiv University; functioning of the educational hub of the Vinnytsia Mykhailo Kotsiubynskyi State Pedagogical University «NotBox».
A wide range of forms of methodological work that can be used in the activities of professional development centers, in general in continuous pedagogical education in order to activate the creative potential of a practicing teacher who seeks self-improvement, is shown.
Laudable Relations
Authors: Kilby Patrick
Published: March 2023

Non-governmental organisations (NGOs), being values-based organisations pose a particular set of issues for academic researchers when working with them. NGOs often engage with universities to provide academic credibility to evaluate the effectiveness of their fieldwork. At the same time, they are nervous about two things: that the evaluation will shatter their belief, they are doing good work, rather than the outcome will always be lauded by some, loathed by others. The second fear is that the NGO being held accountable to donors for activities which are long term and slow in showing sustainable change. This article will draw on the literature as well as my own experiences to explore these issues. My key finding is that the farther away (geographically) from the work an NGO is, the greater in the self-belief of their work. The closer to the local communities NGOs are, they tend to have a tempered view of their work. The article will conclude with some reflections on how a more fruitful dialogue can occur between the two.

Mathematical model of running-in of tribosystems under conditions of boundary lubrication. Part 1. Development of a mathematical model
Authors: Voitov A.V.
Published: March 2023

The paper further developed the methodological approach in obtaining mathematical models that describe the running-in of tribosystems under boundary lubrication conditions.The structural and parametric identification of the tribosystem as an object of simulation of running-in under conditions of extreme lubrication was carried out. It has been established that the processes of running-in of tribosystems are described by a second-order differential equation and, unlike the known ones, take into account the limit of loss of stability (robustness reserve) of tribosystems. It is shown that the nature of tribosystems running-in conditions of extreme lubrication depends on the gain coefficients and time constants, which are included in the right-hand side of the differential equation. It is shown that the processes of running-in of tribosystems depend on the type of the magnitude of the input influence on the tribosystem, the first and second derivatives. The input influence is represented as a product of coefficients and a time constant К0·К2·Т3. This allows us to state that the processes of the tribosystem running-in will effectively take place when the input action (load and sliding speed), will change in time and have fluctuations with positive and negative acceleration of these values from the set (program) value. This requirement corresponds to the running-in program "at the border of seizing".The left part of the equation is the response of the tribosystem to the input signal. Tribosystem time constants Т2 and Т3  have the dimension of time and characterize the inertia of the processes occurring in the tribosystem during running-in. Increasing the time constants makes the process less sensitive to changes in the input signal, the warm-up process increases in time, and the tribosystem becomes insensitive to small changes in load and sliding speed. Conversely, the reduction of time constants makes the tribosystem sensitive to any external changes

Published: March 2023

In this work, a multicriteria optimization of the technology for applying discrete coatings by electrospark alloying in the restoration of bronze parts is carried out. As criteria for optimizing the process of electrospark alloying, tribotechnical characteristics were chosen – the wear intensity and friction coefficient of the coating. As adjustable parameters, those design, technological and operational factors that have the greatest influence on the value of optimization criteria are used: coating material; lubricant; operating current; amplitude of electrode oscillations; sliding speed; specific load. As a result of experimental studies, experimental dependences of wear intensity and friction coefficient for various coating materials, sliding speeds and lubrication conditions were obtained. The use of multicriteria optimization of the electrospark alloying technology made it possible to obtain various alternative coating options and technological parameters of their application for various operating conditions. Of the studied coatings, the most effective is a two-layer coating with the first layer SP-2 and an outer layer of the base material bronze BrAZhMts 10-3-1.5, which is explained by the formation of wear-resistant areas based on Mn and Ni. Multiparametric optimization of the electrospark alloying technology made it possible to reveal a combination of structural and technological factors that ensure the formation of discrete coatings with high operational properties in the restoration of bronze parts.

Published: March 2023

The article is dedicated to the establishment of peculiarities of tire wear of garbage trucks during the transportation of solid waste. Using the planning of the first-order experiment with the first-order interaction effects using the Box-Wilson method, adequate dependencies of wear of garbage truck tires on the front and rear axles due to the transported mass of municipal solid waste and the mileage of the garbage truck were determined. It was established that, according to the Student’s criterion, among the investigated factors of influence, the wear of garbage truck tires on both the front and rear axles is most affected by the transported mass of municipal solid waste, and the least – by the mileage of the garbage truck. The response surfaces of the objective functions – tire wear of the garbage truck on the front and rear axles and their two-dimensional sections in the planes of the impact parameters are shown, which allow to visually illustrate the indicated dependences of the objective function data on individual impact parameters. The dependencies of the number of routes of the garbage truck to the maximum allowable tire wear on the front and rear axles were obtained. The response surfaces of the target functions – the number of routes of the garbage truck to the maximum permissible wear of the tires on the front and rear axles and its two-dimensional sections in the planes of the influence parameters, which allow to visually illustrate the specified dependencies, are obtained. The expediency of conducting further research on the influence of speed, unevenness of the road surface, weather conditions and other factors on the wear of garbage truck tires has been revealed.

Authors: Ismagilov Kamil'
Published: March 2023

Abstract. The purpose of the study is to establish the features of the formation of soybean grain harvest in the territory of the Republic of Bashkortostan. Methods. Analysis of statistical information on soybean cultivation and agro-climatic resources in the territory of the Republic of Bashkortostan, field experience and field observations. The heat supply of soybeans was estimated by the sum of active temperatures, moisture availability – by the amount of precipitation, relative humidity and hydrothermal coefficient (GTK) during the soybean vegetation period (June-August). The sum of active temperatures, the amount of precipitation and the hydrothermal coefficient in the years of the study were calculated using statistical data from the Federal State Statistics Service. The variability of the features was estimated by the coefficient of variation. The nature and degree of interconnection of the features was determined by correlation-regression analysis using the Excel computer program. Results. The features of the process of formation of soybean yield in the territory of the Republic of Bashkortostan have been established. Morphometric indicators of soybean plants SIBNIIK 315 on the territory of the Republic of Bashkortostan have a smaller value than the passport parameters of this variety. The main limiting growth and development of plants, soybean yield in the Republic of Bashkortostan are moisture (correlation coefficient 0.866) and heat (correlation coefficient 0.592). The fertility of the soil in most of the territory of the republic is high enough for the growth and development of plants and does not limit the formation of the soybean crop. It is established that the dependence of soybean yield on the amount of precipitation, the sum of active temperatures and SCC has the form of a single-vertex curve. On the territory of the Republic of Bashkortostan in heat-supplying years, it is possible to compensate for the lack of moisture for the formation of a soybean crop by watering crops.

Abstract. An unsatisfactory microclimate in poultry premises contributes to damage in the form of a decrease in the average daily gain of broilers by 10 %. Purpose of research is to study the effect of relative humidity at the same temperature regime on the immunity and productivity of broilers of the Ross-308. Research methods. The experiment was carried out on broiler chickens of the cross Ross-308 up to 35 days of age. In group II, period 0–1 days of growing broilers, the relative humidity indicators were less than the lower limit of the norm by 10 %, in periods 5–7, 11–16, 20–22 and 26–35 days, the relative humidity indicators were less than the lower limit of the norm by 5 %. In group I, all indicators were recommended as recommended. The bactericidal activity of blood serum was determined by the method of I. M. Karput, lysozyme activity was determined by the nephelometric method according to V. G. Dorofeychuk. Results. As a result of the study, it was found that a decrease in the change in relative air humidity had a negative effect on immunity: the bactericidal and lysozyme activity of blood serum decreased. So, on the 21st day, the indicator of bactericidal activity of blood serum of broiler chickens in group II was lower by 14.2 % (P ≤ 0.05) compared to group I. At 3 weeks of age, the lysozyme activity of the blood serum of chickens of group II was lower by 14.3 % (P ≤ 0.05) compared to the control group. The productivity of birds also decreased to 13.70 % in relation to the control. Scientific novelty. For the first time, we have shown that a decrease in the indicators of relative air humidity at the content of Ross-308 cross broilers during the period of 0–1 days of cultivation by 10 % relative to the lower limit of the norm, during the periods of 5–7, 11–16, 20–22 and 26–35 days – by 5 %, subject to the recommended temperature parameters, has a negative effect on immunity.

Abstract. The purpose of the scientific research is to identify patterns between the development of spice exports in Russia and on the world market. To achieve the goal, the following tasks have been set: 1) to consider the trends in the development of the world structure of exports and imports of spices; 2) identify clusters in the regions of Russia in terms of production and trade indicators and determine the influence of the most significant factors on the dynamics of Russian exports of spices; 3) explore the impact of Russia's export performance on the dynamics of the global spice market. Methods. Economic-statistical, analytical, tabular and graphical methods were used. Correlation-regression analysis was used to identify patterns between the world market and Russian exports of spices. Results. This study identified trends in the development of the global market for flavor products, including an increase in demand for spices by 41 % over the past 5 years. The place of Russia for the analyzed period in the export deliveries of coriander in physical terms was determined. To identify the clusters, the indicator of export localization was used, on the basis of which the regions with export specialization in the supply of coriander to foreign markets were identified. These regions include the Stavropol Territory, whose agricultural producers grow coriander of 99 % purity, that is, fulfilling the criteria of the international standard. The results of the correlation-regression analysis showed that there are patterns associated with the influence of Russian exports of spices on the dynamics of the global market for flavoring products. The article presents obstacles to the development of the spice market on a global scale and measures that contribute to the expansion of the export potential in Russia. The novelty of the results lies in the identification of clusters among Russian regions in the production of coriander and their orientation to the world market, as well as the identification of patterns in the development of spice exports in Russia, including the Stavropol Territory, and the world market, taking into account existing problems.

Published: March 2023

Abstract. The purpose of the article is to develop a modular universal program for the development of agriculture in the region, taking into account global trends in the development of agriculture, demographic processes, achievements in the field of science, the need to provide food to the population. The authors analyzed the global situation of the development of the agro-industrial complex and agriculture, took into account the peculiarities of production and subsequent export of agricultural products in a particular region. Methods. The program-target method was chosen as the main one, which was later disclosed from the standpoint of measures and performance indicators that can be used to guide the formation of the program. The authors relied on the research of foreign and domestic scientists, world centers for research on agriculture and nutrition, statistical data, reviews and analytical reports of authorities and universities. The scientific novelty lies not only in the justification of specific methods of implementing state policy in the field of agriculture, but also takes into account import substitution programs, the development of robotics, the need for a clear definition of quantitative performance indicators. The proposed program has been developed taking into account the binding to specific territories and implementation tools, that is, the fact of the need for zoning has been taken into account. Results. A universal modular program is presented, which can be used in the practice of strategic planning of the region, taking into account the specifics of the development of the agro-industrial complex, existing infrastructure and investment projects. The industrial region (Sverdlovsk region) was chosen as the research site for the article. The authors limit themselves to pointing out measures and performance indicators, without touching on financial issues due to market instability. Also, the issue of developing mechanisms for subsidizing and co-financing was not considered, since they are already, as a rule, established in the practice of the regions and fixed at the level of legislation.

Authors: Bak Gerda , Kovács Tibor , Őszi Arnold
Published: March 2023

A technológiai fejlődés és a biztonság iránti igény növekedésének következtében egyre több helyen találkozhatunk a biometrikus azonosítás különböző módjaival; jelen van az okostelefonokban, illetve számos vállalkozás is alkalmazza, felismerve annak előnyeit. Jelen tanulmány azt hivatott felmérni, hogy a felhasználók körében a biometrikus azonosításról milyen vélemények alakultak ki, illetve miként vélekednek ezekről a módszerekről. A kutatás jelentősége abban rejlik, hogy 2006-ban és 2014-ben az Óbudai Egyetem keretein belül már lezajlott két hasonló céllal megfogalmazott kutatás, amelyet a jelen kutatás során igyekeztünk folytatni, valamint továbbvinni. Az első rész a felmérés azon részét hivatott bemutatni, amely a megkérdezettek biometrikus azonosítási rendszerek ismertségével és használatával foglalkozik. Az eredmények alapján elmondható, hogy a biometrikus azonosítás kapcsán a felhasználók ismeretei bővítésre szorulnak, mivel még mindig sokan csak használják ezeket a technológiákat a hozzá tartozó tudásanyag és tudatosság nélkül.

Published: March 2023

In this article, the authors present a data-driven architecture-based malware exploit analysis as the next part of the Penetration Testing article series. The analysis contributes greatly to investigating malicious attacks, which are becoming increasingly sophisticated in cyberspace, thus posing a significant threat to the information and communication networks of state and non-state actors. To achieve their research objectives, the authors use analytical evaluation methods to define the principles, modular elements and procedures of the data-driven architecture to be applied, where decisions are made based on the available data. On this basis, they have presented an analytical process that can help the public and defence sectors to analyse this type of attack, thus facilitating recovery processes.
Északi-sarki béke vagy háború?
Authors: Molnár Dóra , Szalkai Patrik
Published: March 2023

Az Északi-sark térsége napjaink nemzetközi érdekütközéseinek egyik fontos régiójává kezd válni, ezért egyre több biztonságpolitikai kérdés merül fel vele kapcsolatban. A tanulmány az arktiszi államok speciális, az északi-sarki viszonyokat taglaló stratégiai dokumentumainak összehasonlító és elemző vizsgálata segítségével két fő kérdésre keresi és találja meg az igenlő választ. A hivatalos állami dokumentumok alapján igazolható egyrészt az, hogy az Arktisz egy önállóan értelmezendő és kezelendő régió, amelyre nem, vagy csak minimális mértékben hatnak más régiók konfliktusai. Másrészt az is egyértelmű, hogy Oroszország az arktiszi régióban sokkal inkább az együttműködés jeleit mutatja, sem mint agresszív szándékai volnának. Ez a békésnek mondható arktiszi légkör a nemzetközi szervezetek támogató tevékenysége nélkül természetesen nehezen lenne elképzelhető, az államok feletti szinttel azonban jelen tanulmány nem foglalkozik.
3D nyomtatott lyukasztó töltetek hatásvizsgálata
Authors: Ember István
Published: March 2023

A kumulatív töltetek alkalmazása sok esetben kifejezetten fontos lehet a robbantástechnikában. Ezek az alkalmazási területek egyaránt lehetnek civil, ipari vagy katonai vonatkozásúak. A 3D nyomtatás jelentősége minden tekintetben kiemelkedő, alkalmazása komoly előnyöket hordozhat. A vizsgálat megmutatja, hogy ezek a töltetek hatékonyak lehetnek alacsony sűrűségű béléstestekkel is. A félgömb és kúp alkatelemek esetében egyértelműen meghatározható, hogy melyik képes hatékonyabban átütni a céltárgyakat a vizsgált paraméterek mellett. A több méretben felrobbantott kumulatív töltetek penetrációs képessége tekintetében leszögezhető, hogy ilyen vastagságú céltárgyakat kisebb töltet is képes lehet átütni. Ez további vizsgálatokat igényel.

Legal regulation of the activities of the reviewing police personnel commissions of the USSR in the 20-s of the XX century
Authors: Vasyliev S. V.
Published: March 2023

The scientific study is devoted to the peculiarities of the activities of the reviewing police personnel commissions of the USSR in the 20s of the 20th century. The normative legal acts of the Ukrainian SSR, which established the grounds for the dismissal of police officers, were studied. The legislative and by-laws of the Ukrainian SSR, which regulated the procedure for the creation and operation of commissions for reviewing the personnel of the Ukrainian SSR police in the 20s of the XX century, have been studied. Archival materials reflecting the results of the activities of such commissions have also been studied. New archival documents, which were contained in the Central State Archive of higher authorities and administration, State Archives of Kharkiv and Dnipropetrovsk regions, have been introduced into scientific circulation.

It has been established that the procedure and grounds for dismissal from service in the Soviet police were regulated by the Rules of Service in the Police and Criminal Investigation of the USSR and the Standard Collective Agreement of Soviet Administrative Employees. The legal basis for the activity of commissions for reviewing the personnel of the police was the departmental by-laws of the Main Directorate of the Soviet Workers' and Peasants' Police of the NKVD of the USSR. The specifics of reviewing the personnel of the police in each province depended on the number of employees and the meticulousness of the local police leadership.

It has been found that the normative legal acts that regulated the procedure and conditions of activity of commissions for reviewing the personnel of the police established special, exclusive grounds for the dismissal and bringing to the legal responsibility of police officers.

It has been concluded that the activity of the commissions for reviewing the personnel of the police contradicted the legislative and by-laws in force at the time, which regulated the service and labour relations of the police officers.
