A digital outcrop model (DOM) of the Permo-Triassic limestone of Gunung Keriang, Kedah, was constructed for structural analysis and karst study. Structural analysis of beddings and fractures within the DOM revealed that the limestone beds are characterized by gently inclined planes with NE ̶ SW and NW ̶ SE strikes, forming an upright N ̶ S trending synclinal fold, and being cross-cut by four steeply-dipping fracture sets (NE ̶ SW, NW ̶ SE, N ̶ S, and E ̶ W). The synthesis of these fracture sets indicates that the NW ̶ SE and NE ̶ SW fractures form a conjugate pattern suggestive of E ̶ W shortening, which aligns with the observed N ̶ S fold. Karst development, including elongated sinkholes and cave paths oriented in the NE ̶ SW direction, correlates with the fracture patterns, highlighting the NE ̶SW fracture network significant role in karst formation. The integrated data supports the hypothesis that these fracture patterns are major factors in the dissolution and development of karst features in the region.

Development model of small businesses in single-industry towns of the Russian Federation
Authors:   Samara State University of Economics, Dmitrieva Elena O.
Published: October 2024

Introduction. State program documents aimed to develop mono-profile municipalities recognize small businesses to be the most important source of economic modernization. In this context, there is a need to determine the functioning features of small businesses and to clarify the areas of state support for the entrepreneurial initiatives in implementing various strategies for the development of single-industry towns. Aims. The aim is to investigate the relationship between institutional, economic processes and the conditions for the implementation of small business, formed by the measures of state support for single-industry towns and small businesses, and the development of proposals aimed to develop entrepreneurial initiatives in single-profile municipalities. Methods are theoretical research, statistical and system analysis, expert evaluation and modeling. Results. The paper contains intermediate theoretical and practical results obtained by the author in studying the features of state policy and measures to modernize single-industry towns in the conditions of economic recovery. Based on the systematization of the investigated strategic decisions aimed at diversification, demonopolization and clusterization of the economy of mono-profile municipal entities, it is determined that the strategies for their integrated development can be implemented through the mechanisms for creating territories for outpacing socio-economic development, innovative and industrial clusters, and tourist and recreational zones. Strategic decisions in the development of single-industry towns, to a large extent, determine the tasks, the nature of interaction with the city-forming enterprise and the specialization of small business.Conclusion. It is alleged that the implementation of state measures for the comprehensive modernization of mono-profile municipal entities and support of small businesses in various spheres and industries result in a certain interconnection of institutional and economic processes and conditions in single-industry cities. The models for the development of small business are defined, which may be in demand when implementing the development strategy for single-industry towns. The main areas of small business development in single-industry towns are proposed as follows: systematic support of the entrepreneurial initiatives and the multiplication of human capital, increasing the availability of credit resources and the development of PPPs for the socio-economic development of regions, and the creation (expansion) of markets
Educational process in women’s secondary schools (based on materials from Perm Province of the second half of the 19th – early 20th centuries)

Published: October 2024

The article examines the behavior of students in female secondary educational institutions of Perm Province, most of which were female gymnasiums and junior high schools. The aim of the article is to analyze the problems of the educational process in open all-estates schools, which replaced women’s institutions and were supposed to correct their shortcomings. The study used the methods of retrospective chronological analysis, generalization and interpretation of archival documents. Historical sources associated with the study include, first of all, the office documents of educational institutions, which make it possible to study the reasons why educational work had a significant place in the activities of these educational institutions conceived primarily as educational institutions. Some previously unexplored aspects of the attitude of school girls and teachers to school discipline are investigated. The measures that gave positive results are shown: the introduction of the position of a supervisor, out-of-school supervision, the opening of school dormitories. The lack of communication between the family and the school, which was supposed to form the basis of these schools, and the negative impact of the environment on the morality and academic performance of students made female gymnasiums take over the educational work upon themselves. The depressing state of discipline in the early years was also caused by a sharp increase in the number of students of different social backgrounds and the prevalence of teachers with a low cultural level. However, by the end of the 19th century, educational authorities noted an improvement in student behavior. New challenges for female schools arose for female gymnasiums at the beginning of the 20th century. The critical attitude of some pedagogical currents towards secondary school, supported by society and the press, and the spread of revolutionary ideas led to a deterioration in discipline. This was clearly manifested in some female gymnasiums in the period 1905–1907. The involvement of some of the female students in the protest movement was facilitated by revolutionary-minded teachers. To remedy the situation, the Ministry of Public Education again demanded to strengthen control over the students’ leisure. Until 1917, the situation with behavior in female gymnasiums gradually stabilized (not counting the increased incidence of suicide among female students), and cooperation with parents was outlined. The negative trends that began in 1905 were exacerbated in the last year of the existence of women’s schools. However, as before, they were provoked by radical students. It is concluded that, despite the impossibility of solving some problems and intruding politics in school life, in general, the measures taken by women’s schools yielded positive results.

Published: October 2024

. The article discusses the problem of implementing one of the priority tasks in the learning process at a higher educational institution – the formation of health-preserving competence in students using individualized methods for assessing health status. Particular attention is paid to one of the advanced methods for diagnosing the health status of the subjects – bioimpedance analysis of body composition. The aim of this study is to develop personalized health programs for students, based on the results of bioimpedance analysis of body composition, and experimental substantiation of the effectiveness of the health program. In order to test the effectiveness of a personalized health program, we conducted a bioimpedance analysis of the body composition of 40 first-year physical education students using the InBody 270 hardware complex. The study was conducted at Sevastopol State University in the 2022–2023 academic year. As a result of performing the analysis at the beginning of the experiment, results were obtained that required adjustment of the students’ anthropometric indicators through the development of personalized health programs. A personalized health program, which lasts one month, includes aerobic, strength and wellness blocks, and consists of the following structural elements: (1) setting the main training goal in accordance with the indicators of bioimpedance analysis of the body; (2) determination of an additional individual request to eliminate deformations of the musculoskeletal system and inclusion in the program of additional sets of exercises that affect the health of students; (3) calculation of daily calorie intake, as well as proteins, fats and carbohydrates in accordance with bioimpedance analysis indicators, training goals and individual additional request; (4) variable blocks of focus of training sessions – aerobic block (aerobics and step aerobics, cardio training, interval training and high-intensity training complexes using the Tabata method), strength block (sets of exercises aimed at strengthening the muscles of the trunk using additional weights or with one’s own weight), and a wellness block aimed at increasing the elasticity of muscles and fascia, joint mobility, as well as relieving psycho-emotional stress. The content of training programs is based on the priority goal and additional individual request. In the study, the authors conclude that personalized health programs have a positive effect on increasing the skeletal muscle mass, reducing and maintaining fat mass, and also effectively influence the proportional development of the body through individual training sessions.

Authors:   Mogilev State A. Kuleshov University, Kucherova Anzhelika V.
Published: October 2024

The article substantiates the need to develop a technology for managing the physical training system of cross-country skiers. The goals and content of the procedural components of the ski racer’s physical training system are presented. The procedures for managing, constructing and interacting the components of the physical training system and the essence of this process in the sports training of cross-country skiers are described. Based on a logical and methodological analysis of the periodization of ski racers’ sports training and training process planning, the author’s vision of the technology for managing the physical training system of ski racers is presented. The technology is presented as a certain order of procedures for the interaction of methods and techniques for managing the regulations of training influences on ski racers, during which the athlete’s optimal readiness to realize their physical and psychological potential in training and competitive activities is formed. The technology includes a set of management procedures: diagnostics, forecasting, implementation, correction, organization, which allow regulating the procedural components of the physical training system. The article characterizes all control procedures stated in the technology. The diagnostic procedure includes the implementation of the cognitive-control component of the system. The essence of this component is to identify the athlete’s physical readiness to master the content of physical training. Physical readiness is determined by the dependence of factors that inform about the ability of body systems to perform specific motor activities. The forecasting procedure includes the implementation of the model and forecast component of the system. Forecasting is related to management because it provides reasonable assumptions that the coach uses to make management decisions. The implementation procedure includes the development and implementation of the software and management component of the system. The purpose of the procedure is to develop the content of physical training and its implementation in the form of modular-block programming in the microcycle, mesocycle, and macrocycle. The author presents the modular-block programming of physical training as a comprehensive algorithm for the work of a coach, athlete and doctor to manage, develop and improve the athlete’s educational and training activities. The main variables of the algorithm are the parameters of the loads performed by the athlete in modules and blocks. The correction procedure includes the development and implementation of the synergetic component of the system. The purpose of the procedure is to analyze and synthesize training and competitive results. The organization procedure includes the development and implementation of the organizational and management component of the system. The purpose of the procedure is to organize forms of the training process taking into account external factors.
The phenomenon of the "Moscow Olympiad miracle": Good or evil for domestic education?
Authors:   MGIMO University, Kasatkin Pyotr I. , Gulov Artyom P. ,   MGIMO University
Published: October 2024

The system of Olympiads and creative competitions that has developed in Russia permeates the educational activities of all subjects of the federation, while its core is the All-Russian Olympiad of schoolchildren, held under the patronage of the Ministry of Education of the Russian Federation. At various regional sites, local centers of additional education are created; large sums are invested in modern equipment for schools with Olympiad classes; special educational programs are created at the school–university junction. The Olympiad movement attracts scientific and methodological resources to prepare for creative competitions throughout the country in Russia, while a pronounced rivalry in the ranking of leading regions in the struggle for primacy does not arise due to the unprecedented success of Moscow’s schoolchildren. The statistics of the results of the last decade clearly show the leading role of Moscow Oblast in the Olympiad ranking – both in absolute quantitative indicators and in the stability of performances in many subjects, the capital’s schoolchildren show successful dynamics, which causes the problem of research – comparing the educational achievements of various regions in the field of training for intellectual competitions. However, the leadership of this region gives rise to certain negative consequences for the entire domestic education, and the aim of the study is to reveal such aspects of preparation for intellectual competitions in Moscow. In the study, we rely on the principles of systemic and active approaches, based on the cultural theory of the content of education as the main theoretical framework. The research methods used are both theoretical (analysis of scientific literature on the topic, content analysis of the statistical data set of the Ministry of Education, induction, deduction, categorization) and empirical (interviewing, conversation, survey). As a result of the study, the risks of popularizing the Olympiad movement were identified, among which the growing tendency to change the region of residence and teach schoolchildren in order to access highquality Olympiad training should be highlighted. Our survey of high school students shows readiness for “Olympiad tourism” for the sake of affiliation with more successful teams. We have proposed certain measures that will turn the tide of “leakage” of talented schoolchildren to Moscow’s educational institutions, which in general will be able to favorably affect the development of the Olympiad movement in the country.

The problem of effective and conscious use of modern educational technologies by university teachers as a means of improving the quality of education, the formation of different groups of skills (hard skills, soft skills, self skills) is posed. Based on the problematic analysis of the reports of the heads of departments of one of the universities on the use of technology by teachers, the following effects are highlighted: the “effect of false recognition” of specific technologies, the effect of “professional distrust” of educational and developmental capabilities of technologies, the effect of a contradiction between the subject content and the teacher’s choice between a special teaching method or an educational technology. The problematic points in the organization of joint educational activities at the university due to these effects are highlighted: distortion of the technological chain, the use of technology only at the final stages of studying the topic, the weak influence of the developing capabilities of technology on students, a low level of teaching culture and methodological activity. The inability of a teacher to choose, analyze and reconstruct educational technologies for their professional and personal tasks is, according to the authors, a manifestation of the anthropological deficit of education, which is characterized by the “exclusion” of a person from their education. Educational technology is interpreted as a didactically culturally designed way of organizing joint educational activities, which allows the teacher to achieve subject, meta-subject and personal learning outcomes. It is concluded that it is the teacher that must come to the need to use it: technologies imposed from above consolidate the “educational alienation” of a person from their educational reality and do not allow them to influence their own educational and professional activities.
Artificial intelligence: Ignore or regulate?

Published: October 2024

The technological revolutionary achievements of the modern world inevitably pose a number of issues to humanity that require legal reflection. The most breakthrough achievements of the last few years are artificial intelligence systems. These systems are very successfully integrated into many spheres of life of the world community. To date, many countries have no systematic legal norms regulating the scope of artificial intelligence. The aim of this work is to formulate specific proposals for the legislative regulation of the field of artificial intelligence. To reach this aim, the authors analyzed legislative acts and law enforcement practice in the Russian Federation and in other modern technologically developed countries. Special attention was paid to determining the possibility of considering artificial intelligence as a subject of law. As part of the work, the authors also examined the doctrinal points of view of both the domestic and foreign scientific community. Based on the results of a comprehensive study, the authors propose to consider the possibility of attributing limited legal personality to some artificial intelligence systems: not all artificial intelligence systems should be given certain rights and responsibilities, but only those that have signs of strong artificial intelligence. In this regard, the authors propose to classify all artificial intelligence systems depending on how significant legal facts and legal consequences they are able to generate. It is advisable to structure the list of “advanced” artificial intelligence systems into one group – “strong intelligent systems”. The list of less developed artificial intelligence systems should be included in another group – “weak intelligent systems”. It is advisable classify artificial intelligence systems not on the principle of a generalized enumeration of their functionality, but on the principle of their specific literal enumeration. A specific list of “strong intelligent systems” will be formed and approved by the Government of the Russian Federation. Further, in connection with the proposed classification, comes the idea of attributing legal personality to “strong intelligent systems”. By analogy with the institution of legal entities, it is possible to provide a procedure for delegating certain rights and obligations to strong artificial intelligence, thereby bringing out a new subject in certain legal relations. Thus, the results of the study can outline certain boundaries of the work of artificial intelligence, contributing to the creation of specific constituent documents or protocols of functioning.

Authors:   JSC “Research and Production Association “Bazalt” of the State Corporation “Rostec”, Ozeryakov Sergey V.
Published: October 2024

The problem of boosting the efficiency of extinguishing forest and man-made fires with the use of aviation technology can be solved by implementing into practice of new technical solutions based on explosive dispersion method. Fireextinguishing compound explosive dispersion generates an aerosol cloud which suppresses conflagration zones over vast areas. With the aim of expanding capabilities and enhancing fire-fighting efficiency, a 500kg aerial fire-fighting device ASP-500 was developed by JSC “RPA “Bazalt” as part of initiative development project “Aerosol”. The product is intended for extinguishing and localizing forest fires, as well as for suppressing fire zones during man-made accidents and disasters. ASP-500 is capable of being used from fixed-wing aircraft, helicopters, unmanned aerial vehicles (UAVs). It is expedient to use ASP-500 in conjunction with traditional fire-fighting water release systems, thus ensuring improved performance and economic efficiency indicators. ASP500 application could be an efficient addition to the existing system of forests protection and conservation valid in the Russian Federation, especially in remote or hard-to-reach areas.

Ovarian Hilum Tissue Digestion and Magnetic-Activated Cell Sorting (MACS) of CD31+ Endothelial Cell Isolation v1
Authors: Pant Shravya , McDowell Hannah , M Laronda Monica
Published: October 2024

The ovarian hilum serves as a conduit of nerves, lymphatic vessels and blood vessels for the ovary.1 Digestion of cryopreserved human hilar tissue allows for further primary cell isolation, subsequent experiments and downstream analysis. For example, magnetic-activated cell sorting (MACS) can be performed on cells harvested from digested hilar tissue to isolate desired cell types with cell surface markers. This protocol describes hilar tissue digestion and subsequent MACS isolation for primary endothelial cells using anti-CD31-conjugated magnetic beads.2 Isolated cells and the negative population can then be used in primary cell culture and further downstream analyses. Hilar tissue was obtained from pediatric and adolescent patients undergoing ovarian tissue cryopreservation (OTC) at Ann & Robert H. Lurie Children’s Hospital of Chicago who consented to donate tissue for research under approved IRBs. The hilum is surgically removed from the ovary, processed into 2mm x 5mm pieces and cryopreserved using the previously published slow freezing method: dx.doi.org/10.17504/protocols.io.5jyl8jzr6g2w/v1. Immunofluorescence staining of MACS-isolated cells with Ulex europaeus agglutinin I vascular dye, which binds to endothelial cell glycoconjugates, verified the presence of CD31-expressing cells within our positive fraction when compared to CD31-negative cells collected in the MACS flowthrough. Other interstitial stromal cells were also present in the culture as indicated by positive HMGB1 staining.

An affordable solution for investigating zebra finch intracranial EEG signals v2
Authors: Yekani Milad , Abolghasemi Mohammad-Mahdi , Bahramani Amirreza
Published: October 2024

The Zebra finch is a well-studied animal model for investigating the neural mechanisms of speech-vocal learning, and electrophysiology is the primary technique for understanding the song system. Most of the studies on zebra finches have focused on intracerebral recordings. However, these methods are only affordable for a limited number of laboratories. Different open-source hardware for acquiring electroencephalograph (EEG) signals has recently been developed. It is unclear whether these solutions are suitable for zebra finch studies, as they have not yet been evaluated. Electrocorticography signals can provide a preliminary guide for more in-depth inquiries and aid in understanding the global behavior of the bird’s brain, as opposed to the more common localized approach. We provided a detailed protocol for acquiring intracranial electroencephalography (iEEG) data from zebra finches with an open-source device. We implemented stainless steel electrodes on the brain's surface and recorded the brain signals from two recording sites above two auditory-responsive nuclei. To validate our method, we ran two different experiments. In the first experiment, we recorded neural activity under various concentrations of isoflurane and extracted the suppression duration to measure anesthesia depth. In the second experiment, we head-fixed the birds, and under light anesthesia, we presented them with different auditory stimuli to evaluate event-related potential (ERP). Results showed a significant increase in the suppression duration by increasing the anesthesia depth, and it was evident the ERP response to auditory stimuli was different. These findings indicate that we can successfully collect iEEG signals from anesthetized zebra finches using our methodology. These findings pave the way for future studies to use iEEG to investigate bird cognition more affordably.

In the 21st century, armed conflicts and wars are increasingly being waged in the "Gray zone", that is, outside the boundaries of international law, both in physical space and in other dimensions – informational, cybernetic, cultural, cognitive – mainly by hybrid methods with involvement of irregular formations (private military companies, rebels, terrorists, etc.). As a result, today's interstate confrontation is becoming more and more complex, covering various spheres of national security, characterized by a wide range of negative consequences for the population of the state. The priority tasks of the law enforcement, special, intelligence and other state bodies of the security and defence sector of Ukraine in accordance with their competence are defined as active and effective countering intelligence and subversive activities, special information operations and cyber-attacks, enemy propaganda, countering external threats to the national security of Ukraine, promoting implementation of national interests, etc. Sustainable development of the state requires timely a quantitative and qualitative assessment of negative development trends (threats) in order to prevent crisis situations in ensuring the national security of the state. The proposed method allows for the development of conceptual approaches to the justification of appropriate anti-crisis strategies and programs, as well as recommendations for evaluating the effectiveness of the elimination (neutralization) of negative trends in the development of the geopolitical and military-political situation (threats) in conditions of limited resources. The basis of the method is the justification of the critical values of the risks of the implementation of destructive factors in certain areas of national security, based on a comparison of which with the assessed current risks, anti-crisis measures are developed: strategies, programs and recommendations for each area of national security in relation to each negative trend identified in the process of monitoring the security environment. The method provides the organization of: systematic monitoring of the effectiveness of anti-crisis management with the definition of criteria for making decisions on the order of anti-crisis measures carrying out.

Published: October 2024

This paper offers a comprehensive examination of single-file experiments within the field of pedestrian dynamics, providing a thorough review from both theoretical and analytical perspectives. It begins by tracing the historical context of single-file movement studies in pedestrian dynamics. Then, the significance of understanding the fundamental relationships among density, speed, and flow in pedestrian dynamics through the lens of simple single-file systems is explored in depth. Furthermore, we investigate various traffic systems involving human or non-human entities such as ants, mice, bicycles, and cars, and provide insights. We explore the types of experimental setups, data collection methods, and influential factors that affect pedestrian movement. We also define and explain the common concepts concerning single-file movement, particularly in experimental research. Finally, we present a Python tool named ``SingleFileMovementAnalysis'' designed for analyzing single-file experimental data, specifically head trajectories. This tool provides a cohesive approach to preparing and calculating movement metrics like speed, density, and headway. The article aims to stimulate further research and underscore the areas where future researchers can contribute to advancing and enhancing single-file studies.

As pesquisas qualitativas, mesmo amplamente utilizada ao redor do mundo, são alvos de questionamentos acerca da validade e confiabilidade dos resultados obtidos. Ao convergir para os detalhes, cabe ao pesquisador apresentar de forma clara, precisa e minuciosa aquilo que foi realizado. No campo de estudos qualitativo, em especial na Educação Matemática, o Design Experiment (DE) tem se destacado. Assim, o presente texto tem como objetivo apresentar o Design Experiment como metodologia da pesquisa qualitativa e exemplificar com uma pesquisa empreendida pelos autores. O DE é um método de pesquisa qualitativa intervencionista, o qual possibilita ao pesquisador a realização de redesigns, ou seja, mudanças no percurso metodológico enquanto a pesquisa está em desenvolvimento. A partir dos resultados da pesquisa exemplificada, foram evidenciados os redesigns realizados, apresentando os detalhes das modificações com as devidas justificativas. Em conclusão, se pode afirmar que metodologia qualitativa de DE, aplicada seguindo rigorosamente as fases que a compõem leva a resultados válidos e confiáveis.

AbstractQualitative research, despite being widely used around the world, is the subject of questions about the validity and reliability of the results obtained. When converging on the details, it is up to the researcher to present in a clear, precise, and detailed way what was done. In the field of qualitative studies, especially in Mathematics Education, the Design Experiment (DE) has stood out. Thus, the present text aims to present the Design Experiment as a qualitative research methodology undertaken by the authors. The DE is an interventionist qualitative research method, in which it allows the researcher to carry out redesigns, or research, changes in the methodological path. From your research results, carrying out, demonstrating the research details, and consistently giving your results as justifications and methodologies, will ensure that the applied reliability and the reliable methodology of your results are demonstrably reliable. presented by the researcher.
