Authors: Hermawan Indra
Published: December 2024

This study investigates the relationship between social commerce constructs, customer trust, and purchase intentions, focusing on the context of beauty products on TikTok. Through a quantitative approach utilizing a survey method, data were collected from moeslem women of Generation Z in Medan City. The research findings indicate a non-significant direct relationship between social commerce constructs and customer trust, suggesting minimal influence of these constructs on trust. Similarly, the direct impact of social commerce constructs on purchase intentions was found to be non-significant. However, a significant positive relationship was observed between customer trust and purchase intentions, highlighting the pivotal role of trust in driving purchase decisions. The study emphasizes the importance of fostering customer trust to enhance purchase likelihood in social commerce environments. While direct effects of social commerce constructs on trust and purchase intentions may be limited, efforts to build and maintain customer trust are crucial for boosting purchase intentions effectively. Further research and model refinement are recommended to explore additional factors influencing these dynamics.

Authors: Alsabbah Aya Mohammed , Alsabbah Mohammed Ali , Radaideh Mahmoud Ahmed , Saleh Shafeeka Mohmed , Mehanna Rawan Ahmed
Published: December 2024

Introduction: Osteopetrosis is a clinical syndrome characterized by impairment in the production or function of osteoclasts, leading to bone condensation. Symptoms and their onset depend on the disease’s hereditary pattern.
Case Report: We report a 6-month-old female with dysmorphic features, failure to thrive, lymphadenopathy, hepatosplenomegaly, anemia, and thrombocytopenia. Born term by emergency lower cesarean section due to fetal distress, she was admitted into the neonatal intensive care unit (NICU) for 22 days. Complete blood count (CBC) showed hemoglobin (Hb) 13.6 g/dL, white blood cell (WBC) 14.3 × 10⁹/L, platelet 30 × 10⁹/L, manual 35 x 10⁹/L. At the age of 6 weeks, she was seen in a hematology clinic for thrombocytopenia where she was admitted for bone marrow aspiration. The sample was inadequate, and no megakaryocytes were seen. A skeletal survey was done, it showed evidence of diffuse osteosclerosis overlying the bones, mainly long bones of the upper and lower limbs as well as the metacarpals, metatarsals, and phalangeal bones of both hands and feet. Congenital osteopetrosis was suspected, thus parents opted for second medical advice in Germany where a molecular genetic test confirmed the diagnosis.
Discussion: The patient presented with a wide range of symptoms, the diagnosis of osteopetrosis depends on skeletal radiology and is confirmed by the genetic test. Currently, hematopoietic stem cell transplantation (HSCT) is the only therapeutic intervention available causing it to be the sole opportunity for recovery; however, it cannot be used in all types of osteopetrosis.
Conclusion: The approach to such cases must be comprehensive and must be done by a multidisciplinary team to address and manage the existing symptoms and complications.
«Fruit of Hope»: Recruitment of Kyiv Academy Students to the Hospital Schools in the Mid-18th Century Russian Empire
Authors: Pasichnyk Kateryna
Published: December 2024

The article examines the choice of medical career as a way of social mobility by students of the Kyiv Academy, focusing on the first recruitment campaigns to hospital schools in Saint Petersburg and Moscow in the mid-eighteenth century. Researchers have long noted that students from the Hetmanate and Sloboda Ukraine were a valuable source for imperial domestic physicians. Lesser is known about possible motivations of the volunteers to study medicine in view of their social background. The article argues that a medical career was an active choice for social advancement made not only by clergy students, but Cossacks and commoners as well. Among those who wished to pursue a medical career were also towners. It was rarely attractive to representatives of the Cossack elite at the time under consideration. The article illustrates the process of educational integration of many students from the lower social ranks on their way to becoming participants in imperial project. First, the article examines how this trajectory of social advancement was shaped by the recruitment policy of the imperial medical administration, both declared and implemented. Then, it discusses the students’ travels to the capitals in light of the challenges they faced and the decisions they made on their way to join the medical ranks. The final part examines the social background of the students and their academic performance to understand what the choice of medical profession meant for different social groups and how inclusive this path of social mobility was.
«Nothing can be done without informing and authorizing the Delegate»: Zygmunt Zagórowski, an official of the Ministry of Confessions and Public Education, and the Studim of Orthodox Theology at the University of Warsaw in 1929–1939
Authors: Starodub Andriy
Published: December 2024

The Studium of Orthodox Theology at the University of Warsaw (1925–1939), where graduates of the Kyiv Theological Academy also taught, was one of the unique cultural and educational phenomena of interwar Poland. Its history has already been the subject of a number of special studies by Polish, Ukrainian, and Belarusian authors. Most of them, directly or indirectly, emphasize the complexity and intricacy of church-state relations in the II Rzecz Pospolita. There was an obvious desire on the part of the government to control all forms of the Orthodox Church's «life» as much as possible. The functioning of an Orthodox theological faculty in the capital's university is one illustrative example of the implementation of this policy. The Ministry of Confessions and Public Education comprehensively supervised the process of training Orthodox theologians. Its main goal was not concealed - to guarantee the formation of specialists from among the representatives of national minorities who were undoubtedly loyal to the Polish state. And ideally, their complete «polonization».The article provides an overview of the activities of Zygmunt Zagórowski, an official of the ministry, a delegate of the minister of confessions recognition to the affairs of the Studium boarding school for students. During 1929–1939, he was the main «state controller» of the Orthodox faculty and tried to implement a number of «educational» measures. confidently «competing» for influence over the educational institution with its head, the Warsaw Metropolitan Dionizy (Valedynsky). The delegate's work reports and correspondence with the ministry contain a huge amount of information about the daily life of students and lecturers at the Studium, the existence of contradictions between them on national grounds, and their reaction to «civilizing» efforts and measures for «patriotic» education. It can be stated that, despite the official's intentions, rather modest results have been achieved in these areas (given the scale of the efforts made).
Diarium of Bishop Maximilian Ryllo
Authors: Shmanko Taras , Nowak Alicja
Published: December 2024

The proposed article publishes a small fragment from the six-volume Diarium of the Uniate hierarch Maximilian Ryllo (c. 1715–1793). The text was transcribed from a preserved Latin manuscript and translated into Ukrainian. In the introductory note to the publication of the document, brief information is provided about the life and activities of the author, who was initially a Basilian monk and later became the Bishop of Chełm and Przemyśl, within the socio-religious context of the second half of the 18th century.Thanks to the preserved Diarium, we learn many interesting factual details that the author carefully collected, recorded, and supplemented with his own commentary. He also documented copies of various letters from his extensive epistolary legacy. For the first time, we can trace in considerable detail the process of formation of a young Uniate priest, beginning immediately after his return from studies in Rome and his gradual ascent along the winding steps of his ecclesiastical career, which he had to navigate while performing extraordinary tasks.From Ryllo’s Diarium, we discover numerous previously unknown aspects of the activities of the Basilian Order as a whole, as well as personal characteristics of many monks residing in the monasteries of the vast Kyiv Uniate Metropolitanate. Particularly valuable are the details concerning Uniate bishops and metropolitans, with most of whom Ryllo closely collaborated or corresponded on important matters. The document occasionally mentions contacts between Uniate clergy and Roman Catholic bishops or monastic orders. Interestingly, these references usually do not concern any polemics, misunderstandings, or conflicts, as might be expected. On the contrary, some of them attest to examples of cooperation and even friendly relations.By introducing the texts of Maximilian Ryllo’s Diarium into more active academic circulation, the authors of the publication aim to encourage scholars to study the activities of this bishop, as well as to more actively turn to personal diaries of clergy as extraordinarily rich sources for the history of the Church.

Authors: Kumari Neelam , Malik Dharmpal
Published: December 2024

Background: Chickpea is the largest produced food legume in South Asia and the third largest produced food legume globally. It has been well recognized as a valuable source of protein in India where majority of the population is vegetarian. In spite of biggest producer of pulses in Asian Continent, India additionally imports a large quantity of pulses per year to satisfy the growing domestic demand. The current study aimed to study the growth in production and its possible causes to narrow down wide gap between demand and supply of pulses in India. Methods: The investigation was relied mainly on the secondary data i.e. time series data on area, production and productivity of chickpea in major states and at all India level. The chickpea growing states were selected contributing at least 80 percent of share with respect to area during 2020-21. The paper examined time series data pertaining to the period 1970-71 to 2020-21. The analytical tools like compound growth rate and Cuddy-Della Valle Index were used. Result: In all the major chickpea producing states area, production and productivity exhibited positive growth rate. But the main reason for increase in chickpea production was expansion in area as compared to productivity in recent years due to highest increase in MSP in recent years. At all India level, all the particulars exhibited positive growth. In Madhya Pradesh productivity of chickpea had shown higher instability than area while all the other states and India as a whole exhibited higher instability in area.

Authors: Sahu Chowa Ram , Basak Satyananda
Published: December 2024

Background: In recent times, Machine Learning approaches have gained significant traction in modelling non-linearity features in the field of time series forecasting. In the present investigation, the nonstationary, nonlinearity and non-normality features of the jute price series at the three different commodity markets are dealt using the Machine Learning models. Methods: An attempt has been made to explore efficient Machine Learning (ML) techniques e.g., Time-Delay Neural Network (TDNN) and Support Vector Regression (SVR) for modelling weekly jute prices in different markets of the Coochbehar district (West Bengal). The nonlinearity pattern of the price series is tested by the Brock-Dechert-Scheinkman (BDS) test. Result: The results of present study show that nonlinearity is present in the jute price series. Accordingly, the TDNN and SVR models have been applied for modelling and forecasting the nonlinearity of the jute prices. Finally, the TDNN(1:1s:1l), TDNN(10:1s:1l) and TDNN (2:1s:1l) models are outperformed SVR models in the Coochbehar, Baxirhat and Tufanganj markets, respectively in terms of minimum RMSE (157.61, 176.32 and 136.03), MAE (94.11, 95.67 and 90.45) and MAPE (1.51, 1.54 and 1.41) criteria. Hence, the TDNN model is regarded as the best optimal model for forecasting the jute prices in the Coochbehar district.

The “Global Art Project” as a Reflection of the Interaction of Sociology of Art and Empirical Аesthetics
Authors: Popov Evgeniy
Published: December 2024

The competition and consensus of sociology and empirical aesthetics are conditional concepts. They demonstrate the possibilities of exploring art through a common interest in art. At first sociologists and aestheticians were not ready to apply their scientific potential to a common cause in the study of art. Their ideas were close to the philosophy of art (I. Taine), but the angles of studying art and the prevalent ways of reflection differed. There is competition between them when it comes to their choice of research practices. Sociologists have focused on various aspects of the transfer of symbolic patterns between generations and social communities. Within the framework of empirical aesthetics, emphasis was placed on the formation of aesthetic experience. At the same time, aestheticians considered art as a phenomenon influencing the formation of said experience. In addition, they paid attention to the transmission of such experiences between individual subjects. Initially there were no opportunities to combine the efforts of researchers. The article found that sociologists and aestheticians were approaching a consensus. The meaning of consensus is to “pivot” art towards a person. The article assesses the similarities and discrepancies in the views and approaches of sociologists and aestheticians. Their main task is to identify the institutional characteristics of art. At the stage of coming to a consensus, a general research trend has emerged, called the “global art project”. As revealed, the proposed “project” was aimed at deploying art for the individual.
Intergenerational Transmission of Parental Involvement Practices in Children’s Development
Authors: Dorofeeva Zlata , Kozyreva Polina
Published: December 2024

Using data from the 30th wave of the “The Russia Longitudinal Monitoring Survey — Higher School of Economics (RLMS–HSE)”, the process of intergenerational transmission of parental involvement practices is analyzed by comparing data on current practices involving children with those of parents’ retrospective experiences. The analysis showed that mothers in both generations are more involved in interaction with children than fathers, and the most significant channels for the transmission of parental practices are mother-to-daughter and father-to-son, while the retrospective frequency of father’s involvement is also important for the “father-son” pair. The study reveals factors influencing the transmission process: higher education, urban residence, and having your firstborn at a later age reduce its level, probably due to broader life experience utilized in parenting. It is shown that mothers consistently engage in practices such as attending parent-teacher meetings and taking their children to the doctor, while these practices are less common for fathers and may be influenced by personal experiences and external factors. The practice of taking vacations with a child and physical activity are the most dependent on retrospective experience for both parents, while the reading experience gained from their own father is also important for men. The overall level of parental involvement has been found to be positively correlated with similar practices among other relatives, indicating the involvement of grandmothers in the lives of previous generations. In general, the overall level of engagement of modern parents is consistent with a similar retrospective indicator.
Assessing the Validity of Self-Reported Data on Smartphone Usage: Comparing Subjective and Objective Data
Authors: Saponova Anastasia
Published: December 2024

Nowadays smartphones are the main source of access to online platforms and services and the key driver of internet proliferation both in Russia and abroad. Expanding the functionality of smartphones and registering statistics on their usage creates a new and important source of digital data on user behavior for researchers. However obtaining this type of data requires the development of new methodological approaches and solving a number of technological, legal and ethical issues. A significant step in this process is a comparative assessment of survey data based on retrospective self-reports that are traditionally used for researching online user activity with objective data on behavior based on digital traces of online activity. This article presents the results of an experiment on cross-validation of self-reported data on smartphone usage and digital behavioral data (N = 80). The data for the experiment were collected within the methodological approach referred to as “data donation”, which means that the respondents share with the researchers the data that their mobile devices have already collected. The results of the experiment show a moderate positive correlation between retrospective self-report data and digital behavioral data on mobile phone usage. There is no statistically significant time window effect for estimating the volume of smartphone usage over a short (day) and longer period (current week). It indicates a comparative stable validity of self-reporting and, consequently, its reliability-reproducibility within a week. Thus, when there is no possibility to collect and integrate digital behavioral data into the study, the use of retrospective self-reports may be warranted.
Financial Literacy Volunteers: Individual Choice in new Institutional Conditions
Authors: Moiseeva Darya
Published: December 2024

The functioning of social institutions is the basis of social life. The creation of new institutions can take place through the development of formal requirements and classifications at the level of old institutions. The focus of the study the results of which are presented in this paper is examining the process of appropriating newly created rules and classifications at the level of individuals during the development of a new institution. The methodological framework chosen was M. Douglas’s theory of cognitive institutions, which allowed us to identify the stages of creating a new institution by correlating three definitions of the concept of ‘institution’: a large-scale industrial process, a legitimized social group and a convention. The empirical object was the project ‘Volunteers of Financial Education’ and its participants. The functioning of the project is considered in the broad context of work on improving financial literacy among the population. The detailed characteristic of the institutional design of this project is given, classifications created within its framework are analyzed, the process of origin of the new institution is shown. The study of volunteers’ inclusion in the process of improving financial literacy among the population allowed us to identify five options of individual choice: inclusion through the development of classifications; through the adoption of classifications; through solving the problems of local communities and non-adoption of classifications; inclusion mediated by involvement in other volunteer activities, without the adoption of classifications; participation in volunteer activities on the basis of personal motives without the adoption of classifications. The description of the three levels of the process of institutionalization of new classification grids allowed us to obtain a comprehensive characteristic of the system of improving financial literacy in Russia.
Peculiarities of motivations of IT specialists in crisis conditions
Authors: Lebedeva Olga , Podlesnaia Mariia
Published: December 2024

The article analyzes the data of a qualitative research conducted by the authors at the time of the “testing situation”, i.e. the beginning of the SWO and the subsequent anti-Russian restrictions, among IT specialists and technopreneurs who faced a choice: to stay in Russia or to move to another country after their employer (or with their business). As a theoretical basis of the study we used the grad theory of L.Boltanski and L.Teveno, which made it possible to identify appropriate reactions to the resulting “situation-test”, with reasoned criticism and justification, with perceptions of fairness, as well as to identify the main motives contributing to the move or, on the contrary, leading to the refusal of it. The article attempts to identify the relationship between the reaction to the “situation-test” and the action (relocation or refusal of it) that the respondents eventually took. The authors collected 52 research materials, of which 42 were in-depth interviews with IT specialists relocated (22) and those who remained in Russia (20), and another 10 were interviews, statements, posts, and speeches of leading technopreneurs living and working both in Russia and those who moved abroad due to the SWO. As a result of the analysis of the collected data, the authors made the following conclusions: a group of IT specialists, homogeneous by a number of characteristics, is clustered by the type of reactions to the “situation-test”, depending on which the corresponding choice is formed: relocation or refusal of it. This reveals a connection; moreover, depending on the spectrum of reactions, more unambiguous or, on the contrary, blurred in terms of group behavior, choices and actions are observed.
Cinema as a Subject of Sociological Reflection: Analysis of Scientific Publications
Authors: Levchenko Natalya , Rogovaia Anastasiia
Published: December 2024

This review article is based on the question of the importance of the sociology of cinema as a separate direction in sociological science. In this regard, the article analyses publications devoted to cinema in leading sociological journals from 1976 to the present. The purpose of the study is to identify the sociological interpretation of the transformation of Russian cinema in retrospect, as well as the main trends in the development of Russian sociology of cinema. During the analysis, scientific publications were systematised by year and research areas, which made it possible to more clearly define the current problems of film studies. Starting from the Soviet period, the film industry was considered by sociologists from the point of view of the interaction "cinema-spectator", as a means of propaganda, representation and solving practical problems. The studies were carried out within the framework of the analysis of film distribution statistics, as well as based on the motives and factors of film selection by viewers. It was recorded that the main emphasis of the authors was on quantitative studies, mainly concerning the topics of cinema attendance, their repertoire and audience demand. Some of the works were based on a comparative analysis with foreign studies, noting the lack of interdisciplinary research in the domestic sociology of cinema. At the same time, both in the Soviet period and later, there were practically no works devoted to regional cinema, including ethnic cinema, the history of which began in the first half of the 20th century.
Currently, scientists note that despite the revival of federal cinema, it still does not meet the needs of society, does not become the kind of art that would shape the national culture. There is a lack of theoretical and methodological analysis of sociological research, especially with the use of qualitative methods, on the importance of cinema for Russian society. Further study of the issues of preserving and understanding cinema as an art seems relevant. It is also necessary to look for answers to the questions of what functions it currently carries and / or should carry, what are the alternatives for sociological research in the context of the development of regional cinema. Disclosing the importance of research in the field of film studies will allow us to put forward new problematic and subject fields of the sociology of cinema in the context of current challenges.
The use of man-made waste in strengthening the soils of highways
Authors: Slobodchikova Nadezhda , Klyuev Sergey , Plyuta Kseniya , Klyuev Aleksandr
Published: December 2024

Purpose: analysis of the possibility of using man-made waste to strengthen and stabilize the soils of road surfaces and the roadbed. The use of man-made waste in soil compositions reinforced with inorganic binders makes it possible to reduce the cost of construction and dispose of man-made waste. Objective: to review the available literature for a comprehensive understanding of the possibility of using man-made waste to strengthen and stabilize the soil. Results: the article discusses the ways of using various types of man-made waste to strengthen soils. The ash and slag wastes of the CHP are the most studied. Agricultural wastes such as coffee husk ash, bagasse ash, and cellulose are also of interest. At the same time, the available research has been carried out in rather narrow areas, there is not enough research in the field of assessing the durability of materials under the influence of various factors (moisture-drying, freezing-thawing, dynamic load from vehicles, accumulation of plastic deformations, etc.), there is not enough research in the field of assessing the impact of materials on the environment. Many studies have noted that some types of waste, such as rice husk ash, blast furnace slag and fly ash, need additional research in terms of increasing strength. Practical significance: this review can help in the creation of methods for strengthening and stabilizing soils that would be effective and durable while minimizing the impact of man-made waste on the environment. Additional research is needed to expand the scope of man-made waste in road construction, depending on the type of soil, the structural layer of the highway and the climatic conditions of the construction area.
Selection of loading schemes for assessing the fatigue resistance of frame elements of flat cars
Authors: Cyganskaya Lyudmila , Smirnov Anatoliy , Beyn Dmitriy
Published: December 2024

Purpose: traffic safety is a priority goal for the railway industry. The existing problem of cracks periodically detected during operation in the structures of flat cars requires new approaches to the theoretical and practical assessment of the fatigue resistance and crack resistance of their structures. The problem of crack formation under low temperature conditions is of particular relevance. Methods: an experimental method has been developed for determining the spectrum of vertical loading of platform cars for transporting containers and the spectrum of longitudinal loads for cars operating in areas with low temperatures has been substantiated; a method for assessing crack resistance based on stress extrema determined experimentally has been proposed. The method is based on the principles of fracture mechanics, which take into account the influence of negative temperatures. Results: based on the stress extremes in the design of extendedlength platform cars, determined on the basis of the proposed method, it was established that it is possible to use one well-founded scheme that maximally loads all zones of the car as a test scheme for experimental assessment of fatigue resistance indicators under vertical and longitudinal loads. Using the proposed method, it is possible to determine the size of an acceptable crack-like defect based on the conditions of the initial crack growth. Stress intensity factors obtained on the basis of experimentally determined stress extrema showed that in the design of flatcars of increased length for transporting containers, crack growth is possible at subzero temperatures, which is not consistent with the methodology for assessing fatigue strength of the GOST 33211-2014 standard. Practical significance: the proposed method for assessing the spectrum of vertical loading of flatcars of increased length for the transportation of containers allows, from a variety of options for car loading schemes, to select one scheme for testing, which maximally loads all its potentially dangerous zones. Some research results were used to develop a standard test method for fatigue resistance of extended-length flat cars.

Authors: Znaenok Vyacheslav
Published: December 2024

Purpose: to develop a method of current supply that ensures its uniform distribution over parallel branches of the arm of a rectifier-inverter converter based on IGBT without using equalizing devices for AC electric locomotives with a collector traction drive. Methods: a physical model of a four-transistor rectifierinverter converter arm connected through a controlled power key to a power source was built, on which an analysis of the current distribution was carried out for various methods of its supply to parallel branches. Results: diagrams of current distribution along parallel branches of the arm with different methods of current supply were obtained and analyzed, the influence of the topology of the arm power buses on the circuit parameters was studied. A method of current supply to the arm of the rectifier-inverter converter was developed, providing a spread of currents along the branches of no more than 5%. Practical significance: the results can be used in the construction of rectifier-inverter converter based on IGBT for the “Ermak” series electric locomotives, which will increase the throughput and carrying capacity of the traction sections of the Eastern Polygon.

Authors: Osipov Dmitry , Buynosov Aleksandr , Kud'yarov Ivan
Published: December 2024

Purpose: in case of emergency and emergency situations along the route, the speed of decision-making by the locomotive crew is a critically important parameter in ensuring the safety of railway transport. The main problem is that in some cases, such as the breakage of the brake line of a freight train due to self-disconnection, young drivers incorrectly interpret the readings of the breakage alarm. Together with some other features of the operation of pneumatic devices for train brakes, it takes a considerable time before making the right decisions. As a result, collisions of rolling stock units may occur. Results: this article presents the results of experimental studies of the operation of truck train brakes in the event of a violation of the integrity of the brake line. The features of the operation of the brake line break alarm and the equalizing part of the crane of the driver of the service No. 394/395 when feeding a leak as a result of a brake line break are considered. Practical significance: as a result of experimental studies of the operation of the braking system of freight trains in case of a brake line breakage, graphs of the dependence of compressed air pressure on time in key elements of the braking system of freight trains were obtained. A graph of the dependence of the pressure in the brake cylinders on the length of the train in the wagons is also obtained.

Authors: Mel'nik Yana , Fedorov Andrey
Published: December 2024

The purpose: to find a rational way to build an underwater tunnel in the dense urban development conditions, with the channel width of about 200 m, in unrelated silty soils, that will ensure the minimum depth of the tunnel without additional and expensive measures to strengthen the surrounding soil massive. The article considers the construction of road intersections at different levels, the construction of which has recently increased significantly due to the increase in the volume of highway construction as part of the urban transport network expansion. Methods: the article analyzes the existing methods of constructing urban underwater tunnels in weak soils, and reveals that none of them is rational under these conditions. A promising section of the Pregol River in Kaliningrad was chosen as the site of the study, the construction of a tunnel in this section will ensure not only an increase in the capacity of the highway, but also the passage of cargo flows. Practical significance: a technology has been developed for the phased construction of the subsurface part of underwater tunnels by pushing sections under the bottom of a watercourse without preliminary excavation, which has no analogues in the national tunneling industry.

Published: December 2024

Purpose: the purpose of this paper is to develop software that is able to visualise the operation of an IP telephone network under cyberattacks using the mathematical model proposed in the research paper. The software should provide an in-depth analysis of the impact of attacks on network performance, as well as provide results in an easy to interpret graphical form. Methods: mathematical analysis and counting analysis methods were used to achieve the objectives. The basic mathematical models include equations to calculate impact distribution, restoration time and other network parameters. The programme applies numerical integration and differentiation to calculate the service time distribution. The distribution models include exponential, impulse and gamma distributions. Poisson, Weibull and Pareto distributions were used as distribution functions for random data flow parameters. Results: the software is able to simulate different cyberattack scenarios and their impact on key network metrics, analysing characteristics such as delivery time, packet loss probability and network resilience. The results of the analysis show how different types of impacts and recovery parameters affect network performance, allowing the operator to evaluate the effectiveness of different protection and damage techniques. Practical innovativeness: the results obtained in the course of technological modelling can be used to improve the stability and reliability of telecommunication systems, especially those operating on Supertel equipment. The software provides operators with a tool to analyse network conditions, develop preventive measures and optimise post-impact recovery strategies. It can also be integrated into a decision support system and used to identify cases of unauthorised access.

Authors: Proshin Fedor
Published: December 2024

Purpose: to develop a simulation model of local time scale synchronization at telecommunication network node by using precision time protocol (PTP) assuming that packets are transmitting through optical transport network (OTN). To form a sequence of stages for periodical local clock correction taking into account the local clock drift. To get probabilistic-temporal parameters of this process for evaluating the achievable accuracy. To formulate suggestions for improving the accuracy in view of received parameters and by using more effective mechanisms of synchronization signal transmitting. Methods: comparison of current and perspective mechanisms of synchronization signal transmitting through OTN layer tha can be founded in standards, analyzing of technical documentation and experimental data for generating initial data using in model, simulation modeling with the point of view multi-agent method. Results: the simulation model of local time scale synchronization with the periodical drift correction is developed. The probabilistic-temporal parameters of synchronization message transmitting are received and elements that influence achievable accuracy are obtained. A number of recommendations for its improving is formulated. Practical importance: the simulation results can be implemented for designing transport networks based on OTN and for upgrading current transport networks in a way of implementing OTN with the point of view to provide network synchronization for each attached network and to work correctly with the synchronization information. Also received probabilistic-temporal parameters can be used for modeling at network layer taking into account more complex OTN topologies.

Introduction: Tuberculosis (TB) is an infectious disease with a significant global impact, without treatment, the death rate from TB disease is high (about 50%) Aims: The study conducted in Bhubaneswar aimed to assess tuberculosis disease burden, health-seeking behaviour, and to find the gap of non-compliance in the medicine. Methods: A cross-sectional survey was conducted among TB patients in UPHCs Sahid Nagar and IRC Village of Bhubaneswar, Odisha. All new adult smear positive PTB patients diagnosed and treated in any of the government health facilities within these block PHC areas between 1 July to 31 September 2023, were identified, traced and interviewed using a pre-tested, semi-structured, coded interview. Results: On drug compliance, it was found that patients in the age group above 50 were compliant with treatment 86.2% by taking medicine regularly then their comparison age groups. Education beyond high school positively impacted compliance (100%), as did dependency status (88.9%). Alcohol addiction was prevalent among 47% of male patients and 11.4% of females, while smoking rates were 33.3% among males and 4.5% among females. Dependents consumed less alcohol (17.5%) than employed (55.8%), and younger patients smoked more (36.4%) than older age groups (31.7%). Non-educated patients smoked more (32.5%) than educated counterparts. Self-employed individuals smoked more (75%) than employed (37.2%). Chi square test highlighted that employment correlated with higher alcohol consumption (55.8%), impacting drug compliance negatively. Conclusion: Elderly patients, females, and those educated beyond high school exhibited better treatment completion rates. The study recommends targeted educational interventions to enhance TB treatment.
BİLGİ SOSYOLOJİSİ IŞIĞINDA LACAN'DA ÖZNE

Bilginin anlamlandırılması ve doğru bilginin mümkünlüğü sorusu her dönem pek çok filozof tarafından farklı şekillerde ele alınmıştır. Bilginin ele alınışındaki bu süreç bilen öznenin de bilgi nesnesine ulaşma yolculuğunda dönem dönem farklılaşmasına yol açmıştır. Kültürün ve dogmaların etkisindeki birey Aydınlanma ile birlikte Kartezyen özneye dönüşmüş ardından ise deneyimleyen özneden konuşan özneye doğru evrilmiştir. Postmodern çağda ise öznenin reddi söz konusu olmuştur. Lacan psikanalizinde diğer portmodern düşünürlerden ayrılarak özneyi kuramında kullanmakta, özneyi reddetmemektedir. Lacanyen özne Kartezyen özneden oldukça farklıdır. Bu çalışma bilgi sosyolojisi ışığında Lacanyen özne ele alınarak yapılarak, litertürdeki bu alandaki eksiklik giderilmeye çalışılacaktır. Lacanyen öznenin Kartezyen Özneden farklılıklarına odaklanılarak, Lacan’ın özne ile ilgili diğer kavramları açıklanarak Lacanyen özne kavramı irdelenecektir.
