Authors: Sosin Anton I. , Kozhevnikov Oleg V. , Gribova Inna V. , Kralina Svetlana E.
Published: October 2024

Background: Evans calcaneal osteotomy is one of the recognized surgical techniques for the treatment of flat-valgus foot deformity in children over 12 years of age, which allows simultaneous multiplanar correction. Preoperative planning of the formed diastasis parameters to reduce the number of cases of hypo- and hypercorrection remains an urgent issue.
AIM: To evaluate the results of Evans calcaneal osteotomy using the developed method of preoperative planning and fixation with the individual H-shaped reconstructive plate.
MATERIALS AND METHODS: This study included 64 children aged 12–17 years with symptomatic planovalgus deformity, who were divided into two groups: in the main group, preoperative planning was used according to the developed method; in the control group for intraoperative control of correction was used only fluoroscopy and visual assessment. To study the effectiveness of the developed method, we used dynamic assessment of radiometric parameters and AOFAS questionnaire results before and after surgery. We also took into account the changes in the Foot Posture Index 6 and the Chippaux-Smirak and Stasheli podometric indices.
RESULTS: In comparison with the control group, the main group showed a reduction in the swelling period after surgery, as well as the timing of the onset of full limb support, and a significant decrease in the incomplete correction. Similar dynamics was observed when studying the groups according to the Foot Posture Index 6 scale and podometric indices.
CONCLUSION: The use of the developed method of preoperative planning during the Evans operation has shown its effectiveness for the treatment of flexible flatfoot deformity of the feet in adolescence.
Innovative Social Groups in the Institutional Changes of the Russian Countryside
Authors:   Institute of Sociology of FCTAS RAS, Mukhanova Maria N.
Published: October 2024

The article considers the formation of innovative social groups in the social structure of the Russian countryside, broadcasting the managerial style of thinking and lifestyle of an active subject of agricultural labor. The current model of the agricultural market was formed under the powerful institutional pressure of market reforms. These objective social processes transformed the mentality of rural residents, gave rise to various labor practices, including employment in the informal sector, from which innovative market models of behavior in the agricultural labor market emerged. Using the example of farms and rural entrepreneurs, innovative layers in the labor market are shown, the criteria for which are an increase in agricultural land, production growth using new technologies and digital equipment, access to export markets. The information base consists of data from large-scale panel studies of Rosstat 2011–2022 and the All-Russian agricultural censuses of 2006, 2016, 2021. Institutional changes in the agricultural labor market have been identified, within the framework of which innovative groups are being formed. The development of innovative technologies used in agriculture requires the involvement of highly qualified labor. However, there is an acute shortage of personnel in the agricultural labor market. The wages of a significant segment of jobs in the rural market do not ensure economic stability. The survival strategy remains the main factor in the socio-economic behavior of rural residents, which determines the employment of most of them in non-agricultural sectors in the agricultural labor market. The crisis of agricultural organizations and the arrival of high-tech capitalist forms of production in agriculture cause the migration of the rural population to cities. Despite significant government support for agriculture, there is a shortage of engineering specialties and skilled workers. All these processes hinder the emergence and development of new innovative groups in rural areas. The foreign experience of the functioning of an institutionalized system of information networks and consulting for farmers and small businesses in agriculture is also presented.
Taming the vertical growth of mandible in a growing patient with skeletal open bite: A case report
Authors: Jain Shubhangi , Kumar Puneet , Mehra Prachi , Saraswat Prachi , Paul Pranjal Pratim Kashyap
Published: October 2024

Skeletal open bite poses a significant challenge due to its association with downward and backward mandibular rotation and vertical maxillary overgrowth. Early intervention is critical, especially in patients with a hyperdivergent skeletal phenotype, as facial growth patterns are established early in development. This case report details the treatment of a 9-year-old male with a severe anterior open bite of 6 mm, vertical growth pattern, and class I skeletal relationship. Initial treatment included high-pull headgear with an intraoral transpalatal arch and tongue cribs to control the molar eruption and tongue posture. Over nine months, this approach reduced the open bite by restricting maxillary molar movement and promoting mandibular autorotation. In the second phase of treatment, temporary anchorage devices (TADs) were placed in the parasagittal region along with a transpalatal arch to achieve active molar intrusion and improve incisor exposure. The combination of orthopedic appliances and TADs successfully eliminated the open bite and corrected overjet, while improving incisor alignment, facial profile, and smile esthetics. Cephalometric analysis revealed a reduction in the mandibular plane angle, lower anterior facial height, and improved incisor extrusion. This case highlights the efficacy of early skeletal open bite correction using non-surgical methods, with TADs providing effective molar intrusion and stable long-term results. The integration of headgear and skeletal anchorage offers an effective treatment modality for young patients with severe open bites, potentially eliminating the need for more invasive surgical procedures in the future.

El presente ensayo explora los mapas afectivos o archivos emocionales de comunidades racializadas en España, en concreto, de la afrodiáspora caribeña en Madrid. Cuestiona cómo se prescribe gubernamentalmente el duelo migrante sin contar con la herida colonial, el trauma racial y las geopolíticas de las emociones, y ahonda en el racismo estructural cotidiano. Partiendo de la teoría decolonial y el feminismo negro, así como de las prácticas narrativas en sanación creadas por colectivos migrantes, se realizó una investigación cualitativa, en el período 2023-2024, en la que se realizaron 25 entrevistas en profundidad y dos talleres grupales con la participación de 15 personas activistas antirracistas. Tras una introducción desde una narrativa autobiográfica en la conversación antirracista, se señalan aspectos claves de la noción duelo migrante, asociándola con la herida colonial. Posteriormente, se enfatizan algunas características de la memoria como geografías del desamparo. Por último, apelo a la noción de imaginación, en modo de ensoñaciones o fantasías colectivas que activan la esperanza de traspasar las fronteras del racismo europeo. El artículo crea puentes entre la salud comunitaria, la perspectiva intercultural y el antirracismo.

Foreign historiography on the position of women in Anglo-Saxon society of the 7th – 11th centuries
Authors:   Voronezh State Medical University named after N. N. Burdenko, Boldyreva Irina I.
Published: October 2024

The article focuses on foreign historiography devoted to the place and role of women in Anglo-Saxonsociety of the 7th – 11thcenturies. Based on a review of the main academic publications, three successive periods are identified: the end of the 19th – 1st half of the 20th cc. – the beginning of the study of early medieval English women as subjects of history; 1950–1980s – the beginning of systematic research in this area; the turn of the 1980–1990s to our days – a significant increase in the number of publications due to the wide use of gender methodology. While in the second period medievalists demonstrated the importance of women in Anglo-Saxon society, historians of subsequent generations sought to emphasize their suppression. It is shown that despite the extensive number of special works, in modern medieval studies there is no holistic understanding of the position of women in early medieval England.
Optical Image Processing using Eulerian Amplification
Authors: Wood Dominic , Sufan Umer , Villamil Cesar , Wood Dr Richard
Published: October 2024

Recent advancements in digital photography, particularly through mobile phone cameras, microscopes, and satellite imaging, have made high-resolution image capture increasingly accessible. However, these captured images often contain subtle changes in color resolution and density that are challenging to observe with the naked eye. This study explores the application of Eulerian amplification as a method to detect and enhance such small-amplitude variations, making them visible for improved analysis. Unlike traditional approaches, Eulerian methods are particularly effective for processing smooth structures and high-quality printed materials where minor amplifications in color can reveal significant grading details.
Using a pixel-by-pixel Eulerian path analysis, this method allows for a detailed comparison of color intensity values on a fine 8-bit scale, which ranges from 0 to 255. Through this analysis, color distribution patterns are visualized across the spatial structure of the image, which is particularly beneficial for identifying specific variations in quality in printed materials, such as highly graded cards. To manage large image structures, spatial decomposition using a multi-level Gaussian pyramid technique is employed. By applying temporal filtering within select frequency bands (0.4–4 Hz) at a coarse pyramid level, the algorithm effectively pools spatial data, enabling the detection of color density shifts that may indicate image defects.
The amplified image data is further processed using a classifier neural network, which provides high sensitivity and specificity in detecting edge defects, image centering issues, scuffs, and breakages. The system demonstrates promising results in identifying true positives while maintaining low false-negative rates, thus confirming the reliability of deep machine learning algorithms in high-sensitivity defect detection. This paper presents the significance of Eulerian amplification in optical image processing, offering a robust tool for precise, automated defect detection across a variety of high-resolution image types.
Inclusive Education and Social Inequality: An Anthropological Study of Social Mobility and Access to Education
Authors: Damyanov Kaloyan
Published: October 2024

This research investigates the multifaceted relationship between inclusive education and social inequality, focusing on the potential of inclusive educational practices in Europe, with a specific case study in Bulgaria, to promote social mobility for marginalized populations. Grounded in an anthropological framework, the study seeks to understand how structural and cultural barriers impede access to equitable education for marginalized groups, with particular attention to Roma students, one of the most disadvantaged communities in Europe. By examining the educational landscape in Bulgaria, this research delves into the lived experiences of educators, psychologists, and occupational therapists working to implement inclusive education within a system often fraught with discrimination, limited resources, and institutional challenges.
The qualitative research, conducted in Sofia from February to April 2024, draws on interviews, participant observation, and focus groups to capture the nuanced challenges and successes of those involved in delivering inclusive education. Findings reveal that despite national policies aimed at promoting inclusion, significant barriers persist, particularly for Roma students, who continue to face segregation, prejudice, and limited educational opportunities. Educators frequently report difficulties in accommodating the diverse needs of students within under-resourced schools, while psychological and cultural biases further hinder effective inclusion.
Moreover, the study identifies a critical gap between policy and practice, where inclusive education policies are often poorly implemented due to a lack of cultural competence and institutional support. This gap has direct implications for the social mobility of marginalized students, as education remains a key determinant of their future opportunities. The findings underscore the urgent need for culturally responsive teaching strategies and support systems that are tailored to the unique socio-economic and cultural contexts of marginalized communities. These strategies must go beyond superficial inclusion to actively dismantle the entrenched inequalities that exist within educational institutions.
This study emphasizes the pivotal role of inclusive education in addressing social inequality and promoting social mobility. However, it also highlights the significant work that remains to be done to ensure that inclusive education is truly accessible and effective for all, particularly for marginalized groups like the Roma. By proposing a series of culturally sensitive and contextually informed recommendations, the research advocates for a more holistic approach to inclusive education that can better support the academic and social advancement of marginalized students, ultimately fostering greater equity in educational outcomes and social mobility.

La mirada se ha convertido en objeto de usufructo en el contexto de un capitalismo contemporáneo con la capacidad de convertir a los usuarios digitales en productores del contenido que enriquece a los grandes corporativos posmediales. Una especie de plusvalía escópica que hoy tiene la potencialidad, con el metaverso, de capturar el cuerpo. El nodo articulador de este sistema se produce en lo que llamo estructura tecnológica de recursividad negativa de la imagen de sí, que radica en el uso de las redes y los sistemas para encarar el dolor psíquico que las propias redes y los sistemas producen. Esta espiral negativa es la forma principal de captura del sujeto, potenciada en el horizonte del metaverso como captura radical del cuerpo propio.

Published: October 2024

Purpose: determine the causes of defects in rails in areas of circulation of trains of increased weight and length through modeling the operation of rails in curved sections of the railway track using digital twins. Methods: t study the influence of various factors on rail wear in curved sections of the track, software systems were used ased on the numerical solution of differential equations for the movement of rolling stock and the operation of the railway track under the train. To determine the stresses in the rails in order to predict the development of contact-fatigue defects, dynamic calculations using the finite element method were used. Results: it was revealed that in order to reduce rail wear in a curved section of the track in sections with predominantly freight traffic, the elevation of the outer rail must be calculated based on the actually realized speeds of freight trains. It has been established that at the moment the influence of the amount of rail inclination on rail wear has not been sufficiently studied. As an analysis of the position of the rails at various inclines has shown, for the curve under consideration it is most advisable to use a 1/30 inclination within the limits of a circular curve and with a 1/20 to 1/30 inclination within the transition curve. To reduce the likelihood of contact-fatigue defects occurring in such areas, it is necessary to provide for the implementation of measures to lubricate the side working edge of the outer rail thread and the rolling surface of the inner rail thread within the entire curve. Practical importance: the research results indicate the need to revise the approach to calculating the elevation of the outer rails in curves with heavy freight train traffic. The possibility of extending the service life of rails by revising the system for planning and implementing work on lubricating and grinding rails in curves in areas where trains of increased mass and length operate

Authors: Shehtman Evgeniy , Chernyaeva Viktoriya , Chupyrin Aleksandr , Naumov Andrey
Published: October 2024

Purpose: consider the problem of interaction between turnouts and adjacent sections of a seamless railway track. Methods: statistical data analysis. Results: an analysis of the results of domestic and foreign studies has been carried out, which show that in such areas there is a jump with subsequent extrusion of material of less rigidity and an increase in the slope of the elastic unevenness, i. e., an undesirable phenomenon occurs — a shock wave. The impact force depends on the mass of the rolling stock and the speed of movement, the geometric evenness of the rail track and the chosen approaches to designing the transition zone as a whole. Jump and mainly occurs due to compression and pushing out of structural layers and materials of lower rigidity in the under-rail area. The impact force depends on the mass of the rolling stock and the speed of movement, the geometric evenness of the rail track and the chosen approaches to designing the transition zone as a whole. Jump and mainly occurs due to compression and pushing out of structural layers and materials of lower rigidity in the under-rail area. Shock waves caused by uneven rigidity of sections have negative consequences (the appearance of deviations in level, subsidence, distortions, increased intensity of rail wear, the appearance of rail defects), which increase the cost of maintenance of the railway track. An analysis of the accumulation of residual deformations has been carried out, which shows the systematic formation of geometric irregularities in adjacent areas in the turnout area. Practical importance: from the point of view of the design of the transition zone, the expected advantage will be the differentiation of structural materials and elements and their influence on achieving the optimal gradation of railway track rigidity in the vertical and horizontal (transverse, longitudinal directions), selection of the optimal ratio of the mechanical properties of individual elements of the superstructure structure. It should also be noted that it is necessary to conduct an additional feasibility study of the feasibility of constructing transition sections in the area where the track and switches meet, taking into account the operational features of individual railway lines.
Selection of the function of dependence of the probability of occurrence of residual deformations on loads when determining the optimal elevations of the outer rail in a curved section of the track
Authors: Bel'tyukov Vladimir , Andreev Andrey
Published: October 2024

Purpose: the outer rail elevation in a curved section of railroad track according to the 2021 Guide for Determining the Elevation of the Outer Rail is determined by taking into account unmitigated accelerations, radii (permissible and admissible). Taking these indicators into account allows to determine the best values of outer rail elevations in terms of operational characteristics. But these elevations cannot be called optimal in terms of the amount of work performed during the current maintenance of the track in curves. To determine the optimal elevation, labor costs should be considered throughout the life cycle of the curved section. Since the occurrence of costs is mainly influenced by residual deformations during the life cycle, it was decided to consider the probability of residual deformations during the life cycle. Methods: the choice of the function of dependence of the probability of occurrence of residual deformations on loads was made on the basis o probability theory and regression analysis. The least squares method was used as a method of regression analysis. On its basis, functions with the greatest convergence relative to the function obtained using probability theory were selected. Results: the study found that dynamic loads generated during rolling stock movement on railway tracks follow a normal distribution function according to probability theory. Since certain dynamic loads during operation lead to residual deformations, the probability of such deformations can also be described using a normal distribution function. The resulting function for predicting the probability of residual deformations based on load factors was identified. Practical significance: the research findings can be used to determine the optimal elevation of the outer rail that minimizes labor costs during railway track operation
Write, Talk and Feel Good : Evaluation einer peergeführten Schreibgruppenintervention für Promovierende zur Verbesserung der psychischen Gesundheit
Authors:   , Nickel Sophie Charlott
Published: October 2024

Promovierende weisen im Vergleich zu ähnlichen Bevölkerungsgruppen eine schlechtere psychische Gesundheit (mental health, MH) in Form von höherem Depressions-, Ängstlichkeits- und Stresserleben auf. Dabei spielt die oft erlebte Isolation im akademischen Alltag eine zentrale Rolle. Das peergeführte Schreibgruppenprogramm für Promovierende Write, Talk and Feel Good (WTFG) wurde zur Verringerung dieser MH-Probleme entwickelt. Eine Kontrollgruppenstudie hat das Pilotprojekt quantitativ evaluiert. Dazu wurden zu drei Messzeitpunkten die MH (Maße: WHO-5, PWI-A & GHQ-12) und die akademische Schreibfähigkeit (Maß: SSAW) der Promovierenden erfasst. Das Analysedesign war gemischt längs- und querschnittlich mit einer Gesamtstichprobe von n = 128; davon n = 49 Interventionsgruppe (IG), 76 Kontrollgruppe (KG), 3 unsicher; Geschlecht: n = 80 weiblich, n = 46 männlich, n = 2 keine Angabe; Alter: M = 30.11, SD = 3.59. Als Vorbedingung für die Wahl der weiteren Analysemethoden wurde zunächst die Faktorenstruktur der MH mittels exploratorischer und konfirmatorischer Faktorenanalyse untersucht. Die erwartete Zwei-Faktoren-Struktur (Hypothese 2) wurde nicht bestätigt, sondern jedes MH-Maß bildete eigene, stark miteinander korrelierte Faktoren. Mit zwei Messwiederholungs-MANCOVAs wurden die Haupthypothesen überprüft, ob die positiven Differenzen der MH (H 1.1) und der akademischen Schreibfähigkeit (H 1.3) von t0 zu t1 bei der IG größer waren als bei der KG und dieser Effekt bei der MH auch noch zu t2 (H 1.2) zu beobachten ist. Die Hypothesen wurden nicht bestätigt. Lineare Regressionen haben jedoch einen Zusammenhang zwischen PWI-A und SSAW und post-hoc auch zwischen allen MH-Maßen und SSAW gefunden und damit die Nebenhypothese NH 1.4 bestätigt. Schließlich haben t-Tests gezeigt, dass die IG zu t0 hohe Erwartungen an die WTFG-Gruppen hatte (Forschungsfrage F 3.1) und diese zu t1 als erfüllt betrachtet werden konnten (F 3.2). Zudem wies die IG zu t1 eine sehr hohe Zufriedenheit mit der Intervention auf (F 3.3) und bestätigte zu t2 diese Einschätzung (F 3.4). Die Ergebnisse der Forschungsfragen sprechen für eine Fortführung des WTFG-Angebots, auch wenn empirisch kein Einfluss auf die MH beobachtet werden konnte. Der erwartete Zusammenhang zwischen MH und akademischer Schreibfähigkeit wurde jedoch bestätigt. Und obwohl MH nicht zwei-, sondern dreifaktoriell vorlag, untermauert dieser Befund die Bedeutsamkeit einer mehrdimensionalen Sicht auf MH.

Published: October 2024

Objetivo: O jiu-jítsu, arte marcial de origem japonesa, possui forte identidade com o povo brasileiro que a difundiu internacionalmente, sendo praticado amplamente, atraindo pessoas de todas as idades. No entanto, a prática competitiva entre crianças e adolescentes levanta preocupações sobre especialização precoce e segurança. Metodologia: Este estudo qualitativo e exploratório-descritivo analisou o modelo de competição infantil e juvenil no jiu-jítsu, usando dados da Confederação Brasileira de Jiu-Jítsu. Resultados e Discussão: Descobriu-se que crianças a partir de quatro anos competem em modelos similares aos adultos, com poucas adaptações pedagógicas. Apesar de uma ligeira redução no tempo de luta, poucas restrições técnicas são impostas para proteger a integridade física dos jovens atletas, permitindo projeções, finalizações e estrangulamentos. Conclusão: A pesquisa conclui que a organização desportiva do jiu-jítsu para jovens não está alinhada com as propostas de preparação desportiva de longo prazo. Faltam regras específicas e diretrizes científicas que promovam o desenvolvimento gradual e seguro das habilidades físicas, técnicas e táticas, minimizando os riscos de lesões.

The Prediction And Prevention Of Spınal Anaesthesıa-Induced Hypotensıon With Perfusion İndex And The Effect Of Crystalloid
Authors: Şen Erman , Ekemen Serdar
Published: October 2024

Hypotension is a dangerous and common problem for patients under spinal anesthesia. Spinal anesthesia-induced hypotension(SIH) is often arisen from heart rate decrease and venous blood pooling under the spinal block level because of sympathetic blockage. Prediction and prevention of hypotension will be beneficial for the patients' health under spinal blockage. For prediction, many parameters like perfusion index(PI) have been using. This study aims to research the correlation between the patients' hemodynamic parameters, perfusion indices before spinal block and SIH, and the effectiveness of crystalloid preload before spinal block to the usage of ephedrine. Records from 101 patients between 18-100 years age, who underwent surgery with spinal anesthesia were studied. We enroll patients demografical characteristics, ASA-score, sensory-blockage level, opereation period, the patients' position for spinal block, local anethesic form-dosage, blockage level, patients' hemodynamic and PI parameters in the surgery, hypotension time, efedrin first usage time and dosage from records. These results analyzed with t-test, Pearson-Chi-Square, Wilcoxon-signed-rank and Mann-Whitney-U test. SIH were seen in 25,7% of patients. The incidence of hypotension increases with age and block level. Any corelation between SIH and PI degrees before spinal block was not found, but MAP degrees before spinal block were significantly different in hypotension group. 10ml/kg cristaloid-preload was used 37,6% of patients. SIH was not prevented by cristaloid-preload and cristaloid-preload didn’t affect efedrine dosage-timing. Cristaloid-preload changed significantly patients heart rate and PI. In this study, we found that PI was not predictive factor for the development of SIH. Besides cristaloid-preload don’t avoid development of SIH.

Third-Person Effect theory (TPE) postulates that audiences deny the media's direct impact on themselves but perceive the same media as having a larger impact on others. This study examines TPE and its relationship with Islamic religiosity in shaping perceptions of moral and non-moral issues on social networking sites (SNS) among students at the International Islamic University Malaysia (IIUM). Another objective of this study is to determine how students perceive the effect of moral and non-moral issues in SNS on themselves compared to others. This study employed a quantitative design, with 357 students from the IIUM serving as respondents. The findings indicate that participants perceive moral issues as affecting others more than themselves, which is consistent with TPE. However, non-moral issues are perceived as influencing both the self and others. The results also indicate that Islamic religiosity positively affects the perceived impact of moral issues on others and non-moral issues on oneself in SNS. The data were analyzed using SPSS, with paired t-tests comparing self versus others' perceptions of moral and non-moral issues on SNS. The findings confirm that students perceive moral issues as having a greater impact on others than on themselves, aligning with TPE. Conversely, non-moral issues are perceived as influencing both the self and others, demonstrating SPE. The study also reveals that Islamic religiosity positively influences the perceived effect of moral issues on others and non-moral issues on oneself in SNS.

This study investigated the role of Islamic education teachers in mitigating the negative impacts of TikTok on teenagers in Lampung, Indonesia. This study aimed to assess the extent of TikTok usage among teenagers, identify the associated negative effects, and analyze the strategies employed by Islamic religious education teachers to address these issues. This field study employed a qualitative case study approach, with a sample consisting of 455 adolescents (both male and female) aged 12 to 18 years, and 35 Islamic education teachers who actively participated in the intervention. Data collection was conducted in three stages: observation, interviews, and document analysis. Questionnaires and instruments were designed, and data obtained from Islamic education teachers were analyzed using the Miles and Huberman theoretical framework. The findings revealed that TikTok has a significant negative impact on adolescents, manifesting in various detrimental outcomes. Islamic religious education teachers have already implemented numerous roles and solutions to combat these issues, highlighting the necessity of a comprehensive and serious approach to address this problem. This study underscores the importance of empowering adolescents to resist the risks associated with the unwise and morally harmful use of TikTok, thus protecting their ethical development and well-being.
Traditions of Jayawijaya Muslim Society: Some Perspectives from Islam and Customs
Authors: Ismail Rudihartono , Asso Hasan Abdul Rahman
Published: October 2024

This article explores the compromises made between local customs (adat) and Islamic religious practices in the daily lives of Muslim communities in Jayawijaya, Indonesia. Adat and Islam are two influential elements that profoundly shape societal norms, and their interaction often leads to a dynamic negotiation of values and practices. When Islamic teachings are introduced into a community with deeply rooted traditions, there is often tension between the demands of religion and established cultural customs. This phenomenon is not unique to Jayawijaya. Similarly, when Islam was first revealed in Arab society, it encountered established traditions and customs that had been passed on for generations. In Jayawijaya, local customs are deeply embedded in the lives of Muslims, including initiation ceremonies, marriages, funerals, and other sacred rituals. A significant aspect of these rituals is the communal pig feast, which traditionally occurs in the silimo (courtyard) of homes. Recognizing the need to harmonize these practices with Islamic teachings, the author endeavors to standardize these rituals by replacing pigs with animals that are halal (permissible) for consumption and aligning ceremonies with Islamic law. This study sheds light on the intricate balance between preserving cultural heritage and adhering to religious obligations, thereby providing a framework for similar contexts in which religion and tradition intersect.
Using Logs to Mitigate Process Variability and Dependence on Practitioners in Traditional Business Process Automation Software
Authors: Menezes Thiago Medeiros de , Salgado Ana Carolina
Published: October 2024

Context: Business Process Automation (BPA) is adopted by organizations to improve efficiency, reduce costs, and increase overall business performance. Traditional Business Process Automation (TBPA) is one of the three approaches employed to develop a BPA. TBPA entails developing BPA in a programming language for integrating the relevant applications in the digital ecosystem to execute a given process. Process variability and practitioner unavailability encumber the requirements specification for TBPA software. Objective: This work proposes a log-based approach for TBPA software to make software more adaptable to process changes and reduce reliance on practitioners, by providing a higher alignment among business process requirements and software architecture, and employing process mining to semi-automatically discover the business process during requirements elicitation. Method: The research conducted a case study in a technology institute to assess the approach and report its results in practice. Results: The results revealed significant improvements in adaptability to business process changes and decreased the time spent with practitioners, and, efficiency in development. The approach also presented limitations, including human intervention to accurately obtain the business process, complexity to trace the process into the architecture, data privacy concerns, and risk of network traffic overload. Conclusion: This research demonstrated the effectiveness of traceability between process requirements and software architecture, as well as the use of logs and process mining. These methods made TBPA software enhanced the software adaptability to changes and minimized the reliance on practitioners during requirements elicitation respectively.
