Utilizing Machine Learning to Examine the Spatiotemporal Changes in Africa’s Partial Atmospheric Layer Thickness
Authors: Ibebuchi Chibuike Chiedozie , Abu Itohan-Osa , Nyamekye Clement , Agyapong Emmanuel , Boamah Linda
Published: December 2023

As a crucial aspect of the climate system, changes in Africa’s atmospheric layer thickness, i.e., the vertical distance spanning a specific layer of the Earth’s atmosphere, could impact its weather, air quality, and ecosystem. This study did not only examine the trends but also applied a deep autoencoder artificial neural network to detect years with significant anomalies in the thickness of Africa’s atmosphere over a given homogeneous region (derived with the rotated principal component analysis) and examine the fingerprint of global warming on the thickness changes. The broader implication of this study is to further categorize regions in Africa that have experienced significant changes in their climate system. The study reveals an upward trend in thickness between 1000 and 850 hPa across substantial parts of Africa since 1950. Notably, the spatial breadth of this rise peaks during the boreal summer. Correlation analysis, further supported by the deep autoencoder neural network, suggests the fingerprint of global warming signals on the increasing vertical extent of Africa’s atmosphere and is more pronounced (since the 2000s) in the south-central regions of Africa (specifically the Congo Basin). Additionally, the thickness over the Sahel and Sahara Desert sees no significant increase during the austral summer, resulting from the counteracting effect of the positive North Atlantic Oscillation, which prompts colder conditions over the northern parts of Africa. As the atmospheric layer thickness impacts the temperature and moisture distribution of the layer, our study contributes to its historical assessment for a sustainable ecosystem.
Disruptions in the COVID-19 Pandemic in the Supply Chains of the Automotive Industry as Crucial for the Polish Economy
Authors: Rokicki Tomasz , Bórawski Piotr , Bełdycka-Bórawska Aneta
Published: December 2023

The purpose of this article is to identify disruptions occurring in the supply chain of automotive enterprises operating in Poland during the COVID-19 pandemic and ways to counteract them, taking into account the type of business conducted. The specific objectives are to identify and characterise the types of enterprises operating in automotive supply chains, to identify changes during the pandemic in automotive enterprises, depending on the type of activity, and to show disruptions in automotive supply chains and ways to counteract these disadvantages depending on the type of activity. Automotive enterprises operating in Poland were selected for the study purposefully. A random selection method was used to select 500 automotive companies for the study. The data sources were surveys conducted in June 2023 among 500 enterprises in the form of a direct telephone interview. The Pearson χ2 test of independence was used to check the existing relationships between the type of business activity and the results and responses obtained in the surveys. Automotive companies experienced supply chain disruptions, regardless of the type of business. Most often, these were caused by lockdowns and official closures, low stocks of materials and products, and problems with employees. The type of business conducted was not a factor determining the type of disruptions in the supply chain. All types of enterprises reported similar problems in the supply chain, such as longer order processing times, increased transport, storage, and labour costs, and decreased on-time delivery. Disruptions were most often short-lived, up to 1 year. Car producers indicated that disruptions were longer and even longer lasting compared to sales, maintenance, and repairs. Companies countered disruptions by using mostly operational measures, which were short-lived. Only a small percentage of operators made strategic decisions and countered disruptions over a longer period. The scale of these actions was greater among manufacturers than among dealers and car service companies. The theoretical contribution to science was the identification of disruptions and ways of responding to them in supply chains in the automotive industry, depending on the main types of activities conducted. A practical contribution may be the presentation of enterprises’ reactions to the uncertainty and the recommendation that enterprises have ready scenarios for responding to occurring disruptions.
Advances in Numerical Data Visualization of Flow around a Square Cylinder
Authors: Aguirre-López Mario A. , Hueyotl-Zahuantitla Filiberto , Martínez-Vázquez Pedro
Published: December 2023

In this work, we present a grid study oriented to capture 3D flow simulations around smooth and wrinkled cylinders that could have practical applications in various engineering areas. The study considers three Reynolds numbers, namely, a benchmark Re =2.14×104 and two orders of magnitude above and below it. The main contributions of the paper relate to the optimization of the computational mesh for the spanwise direction of the wind flow that results from the computational-mathematical framework employed, in addition to a novel visualization technique that unfolds features in the recording data that could otherwise be hidden when using traditional plots. We compare our benchmark results with those reported by other authors to conclude that the intermediate resolution grids employed with the widest spanwise provide acceptable results. Furthermore, the new visualization technique offers significant advantages compared to traditional pressure maps, regarding clarity for observing and interpreting local flow disturbances, making variations with Re clearer, and by enabling the detection of asymmetries.
Epidemiology and Diagnostics of Cacao Swollen Shoot Disease in Ghana: Past Research Achievements and Knowledge Gaps to Guide Future Research
Authors: Ameyaw George A. , Domfeh Owusu , Gyamera Ebenezer
Published: December 2023

Cacao swollen shoot disease (CSSD) caused by complexes of cacao swollen shoot badnaviruses (family Caulimoviridae, genus Badnavirus) remains highly prevalent and devastating in West Africa. The disease continues to impact substantially on cacao yield loss, cacao tree mortality, and decline in foreign exchange income from cacao bean sales. Currently, the disease is estimated to have a prevalence rate of over 30% in Ghana, as assessed in the ongoing third country-wide surveillance program. Although achievements from past research interventions have greatly elucidated the etiology, biology, epidemiology, diagnostics, and management of the disease, there are some outstanding knowledge gaps. The role of these information gaps and their effect on CSSD epidemiology and prevalence remain unanswered. This paper summarizes existing scientific knowledge from past research achievements that have provided elucidation on CSSD epidemiology, management options, and guided future research. The discussion highlights the need for multidisciplinary research with modern tools and institutional collaborators to holistically bring clarity on knowledge gaps on pathogen biology, virus–host-–vector interactions, role of environmental and soil nutrient effects on CSSD severity, evolution pattern, role of alternative hosts on virus species diversity, vector population dynamics, and their overall impact on CSSD prevalence and integrated management in cacao plantations.

Published: December 2023

Porcine epidemic diarrhea virus (PEDV) is characterized by diarrhea, vomiting, dehydration, and high mortality rates in neonatal piglets. Two distinct genogroups, S-INDEL (G1a, G1b) and non-S INDEL (G2a, G2b, and G2c), circulate worldwide and are characterized by varying degrees of virulence. Here, we compared the early pathogenesis of a PEDV S-INDEL strain obtained from intestine homogenate (CALAF-HOMOG) or adapted to cell culture by 22 passages (CALAF-ADAP) and a virulent non-S INDEL strain (PEDV-USA) in newborn piglets. After orogastric inoculation of PEDV strains, body weight, temperature and clinical signs were monitored for 48 hpi. Pathological studies were performed at 48 hpi and RNA extracts from jejunal content (at 48 hpi) and rectal swabs (at 0 and 48 hpi) were tested for the presence of PEDV RNA as well as sequenced and compared to the inoculum. Piglets inoculated with PEDV-USA and CALAF-HOMOG isolates showed more severe weight loss, diarrhea, villi fusion and atrophy compared to CALAF-ADAP inoculated piglets. The viral load of rectal swabs was higher in the PEDV-USA inoculated group, followed by CALAF-HOMOG and CALAF-ADAP isolates. Similarly, viral RNA load in jejunal content was comparable among PEDV-USA and CALAF-HOMOG inoculated piglets and higher than that of CALAF-ADAP ones. The comparison of three full PEDV sequences of the inocula with the corresponding ones of pigs after 48 hpi yielded a nucleotide identity >99.9%. This study highlights variations in virulence among S-INDEL and non-S INDEL strains and between S-INDEL isolates obtained from homogenate and cell culture.

Published: December 2023

Staphylococcus aureus is a pathogenic bacteria that is often found to have resistance to antibiotics. Jukut pendul (Kyllinga nemoralis) extract is known to have antibacterial compounds such as flavonoids, tannins, saponins, and steroids. The purpose of this study was to determine the inhibitory ability of jukut pendul ethanol extract against Staphylococcus aureus bacteria. This research used the Kirby-Bauer disc diffusion method with five treatments within five repetitions. Data analysis was carried out using One Way Anova variance analysis. The variation in extract concentration tested was 5, 10, 20, and 40% with 96% ethanol as the control group and Ciprofloxacin as the work control. The results showed that extract concentrations of 5, 10, 20, and 40% were able to inhibit Staphylococcus aureus bacteria with an average inhibitory zone of 9,36; 10,85; 11,64; and 12.15 mm, respectively. The inhibitory zone formed indicates that jukut pendul ethanol extract has moderate to strong inhibitory ability in inhibiting the growth of Staphylococcus aureus bacteria.

As mudanças no ambiente social e as novas tecnologias da comunicação e da informação: uma proposta de análise a partir dos pressupostos da teoria crítica
Authors: Rogeri Raquia Rabelo , De Sousa Daniela Rodrigues , Costa Angelina Carlos , De Freitas Fátima Almeida
Published: December 2023

A Comunicação apresenta a relação entre a Educação e as Novas Tecnologias da Comunicação e Informação (NTCI) analisada a partir de pressupostos da Teoria Crítica. O estudo parte do seguinte questionamento: que contribuições a Teoria Crítica oferece para a análise da relação entre a Educação e as mudanças do ambiente social, das quais participam as NTCI? Objetiva refletir sobre a personal media, que altera as relações comunicacionais, tornando-as pluridirecionais e dinâmicas.  Analisa se elas concorrem para emancipação dos sujeitos, por meio da democratização da informação e das possibilidades de construção do conhecimento, ou para a sua alienação, (de)formando-o segundo os interesses capitalistas hegemônicos. Trata-se de um estudo bibliográfico. Para tratar da relação entre Educação e NTCI, utilizam-se os autores: Machado (1996), Rocco (1998), Lévy (1999), Orofino (2005), Kenski (2007), Médola e Teixeira (2008), Fantin e Rivoltella (2010), Belloni (2011), entre outros. As considerações sobre Teoria Crítica são pautadas nas obras de Adorno e Horkheimer (1978, 1985) e Adorno (1995). Os resultados apontam para a necessidade de assumir a não neutralidade dos meios de comunicação e informação e de desmascarar as ideologias. Compreende-se que a tecnologia não é exterior ao homem, reconhece-se a necessidade de discutir as relações complexas que se estabelecem entre eles. A crítica auto-reflexiva da educação e da sociedade deve ser assumida como princípio e se constitui essência da democracia. Não é uma crítica pessimista, aponta para a possibilidade de recusar o que é imposto e agir sobre o mundo. É necessário buscar a tensão entre o evidente e o real. Desvendar o impacto social das NTCI e suas implicações – políticas, éticas, econômicas, pedagógicas – pode ampliar as possibilidades da atuação dos sujeitos, permitir a superação dos discursos, os ufanistas e os pessimistas, e possibilitar que as NTCI sejam parte de uma nova e necessária cultura escolar.
Invisibility of Game Localizers and the Status of Localization in Slovakia
Authors: Koscelníková Mária
Published: December 2023

The standard industry practice in publishing or audiovisual translation should be mentioning the translators for their work in the credits. When it comes to technical texts, for example manuals or localized texts such as websites, translators or localizers are hardly ever mentioned, especially when translation agencies provide the entire process of translation or localization. Digital games usually do contain credits listing all people working on a digital game, but such lists tend to leave out translators or localizers. The paper aims to investigate the issue of crediting digital game translators or localizers in Slovak digital games and show different crediting practices. We inspect credits in digital games made by Slovak developers and show different crediting practices in the industry. We examine the use of credits in Slovak digital games and rationalize the situation by looking at the localization of digital games, localization training at Slovak universities, and language support for Slovak digital games. The paper contains reviews of 69 selected computer and mobile device games published by 34 studios or developers.

Published: December 2023

This research paper aims to provide a picture of women’s participation in various positions in the field of digital games in Slovakia, such as creators of game content, women involved in eSports, the gaming industry, casual gamers as well as women working in the field of digital game education. Based on theoretical knowledge and qualitative in-depth interviews with seven women working in various positions in the gaming industry, the women’s positive and negative work experiences, and the problems and obstacles linked to their gender were identified. The research is specifically focused on the situation of women in the gaming industry in Slovakia. The results show that female gamers and streamers face negative behaviour from their fellow players and viewers which may result in an array of negative consequences. Findings also indicate that the low representation of women in some areas of the gaming industry is a consequence of prevailing gender roles in society. Furthermore, women’s participation in eSports and competitive gaming is limited due to toxic meritocracy, prevailing masculinity and sexism.

Roles of mobile applications in removing barriers to individual recycling: Case of Türkiye
Authors: Dursun İnci , Tümer Kabadayı Ebru , Yürüyen Hediye
Published: December 2023

Recycling literature lists barriers that deter individuals from engaging in recycling behavior. These barriers comprise cost-related barriers such as the behavior being challenging, personal barriers such as lack of knowledge or laziness, social barriers such as lack of support from family, believing that others do not recycle, and structural barriers such as hard-to-access recycling bins or lack of incentives. Removing or alleviating these barriers is critical for increasing source separation and recycling rates. In addition to other measures taken, mobile applications (recycling apps) developed to support recycling may also have a significant potential for removing certain barriers. This study aims to evaluate the functions of recycling apps used in Türkiye and highlight their potential to support the behavior through removing the barriers. For this purpose, content analysis of recycling apps was performed. Following the PRISMA protocol, 19 applications were identified and reviewed in detail. The findings revealed ten distinct functions provided by apps. The role of each function in removing specific barriers is evaluated. It was found that recycling apps have huge potential to promote individual recycling by alleviating critical barriers when apps are widely used and their functions consistently meet user expectations. Problems related to some neglected barriers and low usage rates are discussed, and implications of findings are provided.
FEATURES OF MENOPAUSE MANAGEMENT AS AN AGING PREVENTION (review article)
Authors: DUBOSSARSKA Z. M. , DUBOSSARSKA Yu. A.
Published: December 2023

Menopause is a physiological transition period in a woman’s life from the reproductive phase with regular ovulatory cycles and corresponding cyclic changes in the reproductive system to the postmenopausal state. The modern concept of female reproductive aging is to recognize the leading role of depletion of the ovarian follicular apparatus. Climacteric syndrome (CS) is the earliest and most common complication of the menopausal period. Most of the pathological manifestations that occur during peri- and postmenopausal periods are associated with an estrogen deficiency state and are subject to correction by hormone replacement therapy (HRT). In addition, in postmenopause the frequency of many diseases that reflect the biological aging of the body increases. Therefore, in order to develop optimal HRT regimens and understand the role of a rational lifestyle in the correction of these manifestations, it is necessary to consider the evolution of views on the menopause in general and HRT in particular. Until now, there has been no consensus regarding the tactics of a differentiated approach when prescribing HRT, taking into account existing systemic disorders in women with a history of “diseases of civilization.” Individualization of HRT in patients with a history of impaired reproductive function should be determined not only by the clinical variability of the manifestations of CS, but also taking into account the presence of extragenital pathology, which requires the implementation of our proposed diagnostic algorithm and the basis for the development of such a HRT strategy.
Neuroprotective mechanisms of physical activity

Published: December 2023

It is known that the adaptive capabilities of the brain are not unlimited and deteriorate over time. It is a proven fact that aging is one of the main risk factors for the occurrence of neurodegenerative disorders, mainly due to poorer immune protection and recovery of the body. Therefore, scientists have recently been paying attention to the search for additional methods of management of neurodegenerative pathologies for their more effective prevention. Among the identified methods, special attention is paid to physical activity, the results of which investigation indicate a powerful neuroprotective effect, however, the mechanisms of this phenomenon have not yet been conclusively proven. Therefore, in this systematic review, the main neuroprotective mechanisms of exercise were described and demonstrated using the methods of analysis and systematization of literature sources from PubMed, Web of Science, Elsevier, and Google Scholar databases. As a result of the study, it was established that a significant protective effect on the nervous system is achieved thanks to neuroendocrine regulation due to the influence on the hypothalamic-pituitary-adrenal axis. Another factor is the development of stress due to physical exertion, although the mechanisms of this phenomenon are still a subject of debate among scientists. However, it was proved that the consequence of such influence is the optimization of the work of neurotransmitters, in particular, in the locus coeruleus, as well as the activation of the antioxidant system, which allows to disrupt the number of free radicals in the brain structures. Relatively new is the role of moderate-intensity exercise in increasing the expression of neurotrophins – key factors of neuroplasticity, in particular BDNF, IGF-1, NGF and VEGF, which expands the possibilities of potential effects on the brain and its neuroprotective properties. The obtained results allow the use of physical activity as an additional therapy in the treatment and prevention of neurodegenerative pathologies, however, further practical research is needed to find a specific algorithm and schedule of classes with high application efficiency.

Sobre la teoría de objetos geométricos
Authors:   , Salvioli Sarah E.
Published: December 2023

El concepto de objeto geométrico ha estado bajo la atención de los matemáticos desde los comienzos de este siglo. Muchos fueron los intentos realizados para clarificar y desarrollar el tema hasta la aparición en 1936-37 de los resultados publicados por J.A. Shouten, J.Maantjes y A. Wundheiler. A partir de entonces la mayoría de las publicaciones estuvieron dedicadas al estudio de situaciones particulares o a la clasificación de los objetos geométricos. Recién en 1952, con la tesis de A. Nijenhuis, apareció un tratamiento completo de la teoría. En este trabajo el problema se encara desde un punto de vista que podríamos llamar clásico o numérico: un objeto en un punto P de una variedad M es una correspondencia que asigna a cada sistema coordenado definido en P un conjunto de N números llamados componentes. El énfasis está puesto en el hecho de que si el objeto es un objeto geométrico las transformaciones de sus componentes son representaciones del grupoide de elementos de transformaciones de la variedad M. Nuevos intentos de formular la teoría de objetos geométricos fueron hechos por Maantjes-Laman(1953) y Kuiper-Yano(1955). En ambos casos un campo de objetos geométricos es una sección de un fibrado que goza de especiales propiedades, pero en la primera de las publicaciones el espacio del objeto y el grupo de transformaciones que opera sobre él son los elementos de mayor importancia. Nosotros presentemos aquí un tratamiento funtorial de la teoría de objetos geométricos inspirada en el fibrado natural de A. Nijenhuis (1953).

Published: December 2023

The article contains the results of statistical processing of geochemical data for rocks of the Porokhovskoe tungsten deposit (South Urals) obtained during systematic geological exploration. Statistical samplings were formed for various types of host rocks: andesites and their tuffs, shales, metasomatites (including sericite-quartz, epidote and chlorite-bearing) and skarns. It is established that all rocks of the Porokhovskoe deposit are characterized by increased contents of W and Mo and, to a lesser extent, Be, Cu, Li, and Zn and by stable groups of correlated elements, both associated with greisenization process and those inherited from the

protolith. No zoning is revealed in the distribution of elements in relation to the Yugo-Konevsky leucogranitic pluton, which is considered the ore-generating for the deposit. No correlation between W and Mo was identifed in all types of host rocks. A number of statistical methods is proposed for the identifcation of promising areas with unclear W-Mo mineralization in rocks.

Published: December 2023

As part of the synthesis of new matrix materials for vitrifcation of highly active radioactive wastes, the crystalline phases formed during rapid cooling from melts of the Na2O–Rb2O–SrO(Ba)–B2O3– SiO2–Al2O3–ZrO2 system with a high Rb and Zr content (up to 10 mol. %) are found and studied. The presence of numerous Zr and Rb-bearing crystals in samples is established by electron microscopy, X-ray diffraction and Raman spectroscopy; their morphology, chemical composition and spectral characteristics are studied. It is concluded that these crystalline phases form due to the excessive content of individual components of the melt and their formation is responsible for the undesirable fnal local heterogeneity and crystallization of matrix materials.

Published: December 2023

Bone tissue is a physiogenic organomineral aggregate consisting of organic (collagen, fats, sugars) and mineral (hydroxlyapatite) components. Osteoporosis is one of the most common bone diseases leading to disruption of bone tissue mineralization processes. To study the dynamics of changes in

hydroxylapatite during osteoporosis, an experiment was conducted on laboratory animals with the simulation of systemic osteoporosis using ovariectomy (the surgical removal of an ovary or ovaries). The chemical composition of the mineral component of bone tissue was studied using electron microprobe analysis with further statistical processing of the results. The osteoporosis of bone tissue results in an increase in the content of isomorphic Mg, Al, and K in hydroxylapatite. A signifcant role of Al in the development of the disease was established using multivariate statistics methods. The X-ray diffraction revealed the increase in the unit cell parameters of hydroxylapatite with the osteoporosis progression. The results of IR spectroscopy showed the presence of a carbonate group in hydroxylapatite, the content of which decreases with disease.

Introduction. The article analyses the current state and transformation of the mechanism of theft of mobile communication devices. The main ways of committing thefts are studied, as well as the techniques and methods used in this process. The relevance of the research is determined both by the high number of committed thefts of mobile communication devices and by certain aspects of legal regulation of the documentation process in their investigation.

Methods. In the research various methods were used, including the universal scientific method of historical materialism; general scientific methods of cognition (comparison, ascent from abstract to concrete, analysis, synthesis, induction, deduction, generalisation, classification, abstraction), private scientific methods (formal-legal, comparative-legal, method of interpretation of legal norms, dogmatic), interdisciplinary method of formalisation.

Results. The author analysed the most typical investigative situations in the investigation of mobile communication devices thefts and concluded that the process of documenting such crimes is related to their investigation being aimed at collecting, recording and analysing evidence related to the crime in order to identify the responsible parties and ensure the identification of the perpetrators of mobile communication device thefts. Certain difficulties are associated with the fact that documenting the theft of mobile communication devices is a complex integrated multi-stage task that requires careful attention and co-operation between all participants in the criminal justice process involved in the investigation of a particular criminal case.

Authors: Mozhaykina Viktoria
Published: December 2023

Introduction. The defining role for the penal enforcement legislation of the Russian Federation is played by the principles that make it possible to establish the vector of the main directions of penitentiary policy and to subordinate the social relations arising in this area to uniform principles. Despite its high doctrinal and practical significance, the system of principles established in Article 8 of the Criminal Punishment Code of the Russian Federation, does not agree with modern legislative innovations and trends in the practice of execution of criminal penalties. The above dictates the need to revise and optimize the principles which are specific to this field.

Methods. The article is based on a set of general scientific and private scientific research methods, among which the most widely used dialectical, logical, statistical, comparative legal formal legal methods.

Results. Based on the study of modern trends in the development of legislation and practice of the execution of criminal penalties, the author comes to the conclusion that it is necessary to supplement the list of principles of penal enforcement legislation with the principle of resocialization.
Secrecy as an intersectoral socio-legal phenomenon
Authors: Tambovtsev Andrei
Published: December 2023

Introduction. At all times, secrecy has been associated exclusively with secrecy and criminal (political) investigation as the forefather of operational investigative activities. At the end of the XX – beginning of the XXI centuries, there appeared hypotheses about the attitude of secrecy not only to conspiracy and operational investigative activities, but also to other branches of law and areas of social life.

The scientific and legal community discussed the problem more and more often within their community. The relevance of this study is due to the conflict of modern scientific views of the legal community on the sociolegal phenomenon of secrecy and the polemic of its attribution only and exclusively to the field of operational investigative activities. Having analyzed modern law enforcement practice and current legislation in various spheres of life, the author puts forward and substantiates the thesis about the interdisciplinary nature of the institute of secrecy.

Methods. Methodology: the study used general scientific dialectical, comparative legal, formal logical methods and the method of content analysis. The study made it possible to identify facts and evidence of the existence and functioning of the institution of secrecy in social spheres unrelated to the ORDO and law enforcement in general.

Results. Based on the results of his own research and the results of numerous previous scientific studies of other lawyers, the author comes to the conclusion that the socio-legal phenomenon of secrecy is objectively characteristic of many spheres of society’s activities in addition to its purely operational-investigative and law enforcement activity, which proves its interdisciplinary nature.
The language and style of criminal procedure documents of the criminal prosecution bodies of the BSSR of the mid-twentieth century

Published: December 2023

Introduction. Studying the history of criminal procedure institutions allows to fully comprehend their essence, as well as to comprehend the logic of the legislator who formulated a certain rule of law in one form or another. In this regard, the analysis of archival criminal cases is of particular scientific interest, the study of which contributes to the objective study of the documentation of the pre-trial criminal procedural activity of the criminal prosecution bodies of the Byelorussian Soviet Socialist Republic (BSSR) of the mid-twentieth century and its further evolution.

The purpose of this article is to study the documentation of the pre-trial criminal procedural activities of the criminal prosecution bodies of the BSSR of the mid-twentieth century.

Methods. The methodological basis of the research is a combination of general scientific (dialectical, deduction, induction, analysis, synthesis, etc.) and private-scientific methods (legal-technical, comparativelegal, empirical, etc.).

Results. In the course of the study, the conclusion was formulated that the pre-trial proceedings of the BSSR in the middle of the mid-twentieth century were to some extent influenced by pre-revolutionary legislation and law enforcement practice, which was reflected both in the provisions of the Criminal Procedure Code of the BSSR and in the activities of the Soviet criminal prosecution bodies. On the other hand, the systematic deviations of investigators and interrogators from the archaic requirements of the Soviet criminal procedure law subsequently led to the transformation of such actions into the norms of the law of the Criminal Procedure Code of the BSSR of 1961 and the Criminal Procedure Code of the Republic of Belarus.

In addition, attention is drawn to the preservation of the rules of registration of certain procedural documents (known at least since the beginning of the twentieth century) in the modern activities of the Belarusian criminal prosecution bodies. In the process of writing the article, the procedure for conducting face-to-face interrogation and the presentation for identification at the stage of development of the criminal process, when they such have not yet been considered by the legislator as investigative actions, is considered.

Methods. The basic techniques and methods comprise the questionnaire “Assessment of professional maladaptation” (O. N. Rodina), the questionnaire “Determination of integral forms of aggressive communication” (V. V. Boyko), The Maslach Burnout Inventory (MBI) adapted by N. E. Vodopyanova, the questionnaire “Professional deformation of correctional officers” (E. M. Danilina). An additional survey included “Test of meaning-life orientations” (MLO) (D.A. Leontiev).

Results. The research revealed the significant components of the model of professional burnout of a correctional system officer. They include external locus of control, emotional shifts, work experience as a penal system officer, tendency to auto aggression, ability to become violent, decrease in activity, enjoying aggressive behaviour and ability to reflect aggression. The study found that the external locus of control is correlated with a high and moderate level of professional burnout. Beside the external locus of control, the main personal characteristics influencing the development of professional burnout of pretrial detention centre officers are emotional shifts with positive correlation with psycho-emotional exhaustion. According to the data, the factors of professional burnout of pretrial detention centre officers are personal features related to the emotions and volition of a person.
