Oxidative stress and aging are known to alter the copy number (CN) of satellite III repeat (1q12) (SatIII(1q)) and telomeric repeat (TR) in the DNA of human cells. The extreme conditions of Antarctica could potentially affect the CN of these repeats in human blood cells, which may be associated with inhibition of the antioxidant system and activation of apoptosis. In this work, we analyzed the CN of ribosomal DNA (rDNA), SatIII(1q), and TR repeats in the leukocytes of 11 male members of the expedition to Vostok station in 2019–2020. To observe dynamic changes in the number of repeating elements of the genome and the degree of their oxidation, six blood samples were taken: before arrival in Antarctica, after 27, 85, 160, 270, and 315 days of wintering. To analyze adaptive changes, the expression levels of the BAX, BCL2, NOX4, NRF2, SOD1, and HIF1 genes were measured. We detected a decrease in SatIII(1q) CN and an increase in TR CN against the background of a stable rDNA CN in human blood cells during wintering. These changes, along with a decrease in the 8-oxodG in DNA, are associated with an increase in the activity of the NOX4 gene, a decrease in the activity of the NRF2 gene, and an increase in the expression of the proapoptotic protein BAX. Thus, wintering in Antarctica stimulates an adaptive response in the human body, which includes increased elimination from the bloodstream of “ballast” cells with a high level of DNA oxidation, a high SatIII(1q) content, and a low TR content. An increase in ROS levels due to chronic activation of the NOX4 gene along with the blocked NRF2 gene may play a significant role in the development of the response.
Changes in the Inter-Korean Policy of the DPRK and the ROK and Prospects for the Development of the Situation on the Peninsula
Authors: Asmolov K. V
Published: October 2024

At the December plenum of the Central Committee of the WPC in 2023 and the January session of the National Assembly of the DPRK in 2024. North Korea has radically changed inter-Korean policy, abandoning the course of "unification of the country." The authorities have disbanded relevant structures and intend to "completely remove from the national history of our Republic the very concept of "unification", "reconciliation" and "compatriots". According to Kim Jong-un, the DPRK and the Republic of Korea have finally become "hostile states" for each other, their relations are no longer determined by belonging to the same people, so the peaceful unification of the Korean peninsula is no longer considered possible. This course testifies to the recognition by the country's leadership of objective reality and does not lead to an increase in the probability of an inter-Korean conflict initiated by Pyongyang. This change of course was largely the result of the processes in the south of the peninsula, where the government of Yoon Seok-Yeol, on the contrary, strengthens the rhetoric of "achieving peace through force". The author considers President Yoon's speech on March 1, 2024, formally dedicated to the 105th anniversary of the March 1, 1919 movement to be a sign of the new course. This speech can be considered as a program of a new inter-Korean policy aimed at eliminating the DPRK by the international community. The changed relations between Seoul and Pyongyang should be perceived as a consequence of changes in the world order and the global security architecture, as the concepts that do not meet the new reality are revised or canceled. At the same time, Russia may be satisfied with the presence of a cold war on the peninsula, if it does not turn into a hot one, as well as with the further rapprochement between Moscow and Pyongyang, united by a common threat.
Integration of Gentry and Merchants in Singapore’s Chinese Community and Their Realist Policies (1877–1941)
Authors: Chen Yao , Yu Danhong
Published: October 2024

In colonial times Chinese merchants in Singapore aspired to the status of gentry, played the role of gentry in society, and performed social functions of gentry. At the same time, some gentry became involved in trade to gain, maintain and expand their power and prestige. We call the phenomenon the integration of gentry and merchants. In the traditional research paradigm scholars have analyzed the phenomenon in terms of national, political, and cultural identity. It is true that Chinese merchant leaders in Singapore of that time considered themselves patriots of China and were devoted to China at heart. But this article reinterprets some aspects of the Chinese diaspora in Singapore. The authors outline three major sources of power: personal business networks, the Chinese government and consulate, the colonial government. To gain power, merchants used five main strategies: expanding cultural nexus of power, interlocking officership, leading political or cultural movement, political loyalty, family legacy and marriage alliances. There were four main organizational models: dialect group association, chamber of Commerce across dialect groups, British-Chinese association, and modern political organizations. Their activities are divided into four types: philanthropic business, political movements, social reform, comprehensive activities. The integration of gentry and merchants and their realist policies reflected social needs, traditional Chinese values and psychological needs. It was the essence of their economic, social and cultural activities to acquire, maintain and expand their wealth, power and prestige.
Gabon: The 2023 Coup in the Context of Postcolonial History
Authors: Vasiliev Alexey M.
Published: October 2024

The global geopolitical transformations of modern times are deforming the world order that emerged in the post-war period. These transformations marked the beginning of the end of French dominance in West and Central Africa. There is a rapid degradation and collapse of the military-political system “Fransafrique”. Over the past 3 years, armed coups have occurred in Mali, Guinea, Sudan, Burkina Faso, Niger and Gabon. The violent change of power in all these states had much in common, but there were also significant differences in what was happening in these countries. The article examines the features of the 2023 military coup in the Gabonese Republic and its distinctions from coups in other states in this region. In particular, the Elyse Palace’s loyal attitude towards the initiators of the putsch is noted, and the reasons for this unexpected tolerance are revealed. This also explains the quite benevolent attitude of the putschists towards the presence of French troops on the territory of Gabon. All the coups that have happened in recent years have little in common: the impoverishment of the broad masses, galloping inflation and unemployment. Everywhere there was massive support for the rebel military from civil society.
Modern Perception of Water Scarcity Issue in African Countries
Authors: Berezhnov Andrei I.
Published: October 2024

The article analyzes how water scarcity on the African continent is perceived by the United Nations, Russia, and African countries. Water is an important part of the UN Sustainable Development Agenda. The international decade for action on Water for Sustainable Development was declared from 2018 to 2028. The author studies the United Nations’ vision of the water issue by using 2 indicators that often appear in reports of this international organization and its subordinate structures, namely access to water supply services and the level of water stress. These parameters are compared with the results of public opinion polls conducted by the African research center “Afrobarometer” and search query statistics in Google Trends. In order to identify Russian society’s ideas on the water issue in Africa, literary works, as well as publications of the TASS news agency were analyzed.
Economic and Political Aspects of Egypt’s Accession to BRICS
Authors: Ufimtsev Andrey A.
Published: October 2024

The article focuses on the reasons why the Egyptian leadership decided to join BRICS in January 2024. The analysis of the Egyptian leadership’s public rhetoric has shown that the key motives for joining the organization are usually related to the economy: Egyptian politicians most often talk about expanding cooperation with the organization’s member countries, dedollarization and the New Development Bank. This is due to the fact that Egypt is facing serious economic problems, which relate to budget deficit, high inflation, trade deficit and devaluation of the national currency. BRICS cannot solve these Egyptian problems and is not a “silver bullet” but the benefits of joining, associated with economic cooperation and the New Development Bank, far outweigh the costs, which are limited to a small risk of deteriorating relations with the United States. BRICS does not impose rigid obligations on its members, which makes the organization attractive to countries with different political systems, allowing them to maintain balance in international relations with different actors thereof (such as the United States, China, Russia, India, European Union countries etc.)
The Port and Logistics Dimension of the UAE’s Strategy in Africa
Authors: Shelkovnikov Andrei I.
Published: October 2024

The Russian Federation, expanding cooperation with the countries of the “world majority”, pays special attention to cooperation with Africa. Moscow has held two summits and adopted specific action plans for the development of relations with the states of the continent. However, further progress rests on limitations and difficulties of a financial and economic nature, problems of access to the markets of African countries, including our grain products. It is important to study and take into account the proven experience of third countries in these matters. In this regard, a special place is occupied by the study of approaches followed by the UAE, which has a well-developed and proven strategy for promoting its interests in Africa based on the accelerated development of port and logistics infrastructure, assistance to international and intercontinental trade. The article contains an analysis of the UAE’s strategy towards Africa, with an emphasis on its port and logistics dimension. Special attention is paid to the study of the experience of the Emirati port operators. The UAE’s activity in certain sub-regions of Africa is considered; the existing problems and components of the success of specific projects are noted. The question is raised about the possible combining the efforts of the two countries: the UAE - in the field of port and logistics facilities, the Russian Federation - in the field of their physical protection.
African Episodes on Russian and Bengali Literary Scenes
Authors: Sarkar Archan
Published: October 2024

The present work studies images of Africa as they appear in fictions and poems. For this purpose, literature in Russian as well as Indian, Bengali in particular, have been considered. The literary works that have been studied here, from one hand, reflect the images of African lands, air, seas and forests which do exist since the primitive era of their creation and, on the other, enliven the scenes of happenings that had taken place on this continent during the modern times. It analyses the details of these images in the works of Russian and Bengali poets and writers, reveals that the place of Africa in literatures of the said two languages was largely influenced by the geographical and historical realities of this eastern continent. It also brings to light that the geographical and historical details are not mere descriptions here. They often happen to be decorative mediums to reach artistic goals. The very disclosures made on the basis of African episodes have been elaborated in the given work in different literary genres and trends.
Asiavaltuus oikeudenkäynnissä : este pääsylleoikeuksiin vai suojaoikeutta hakevalle?
Authors: Koulu Risto
Published: October 2024

Asiavaltuus (vanhalta nimeltään asialegitimaatio) on prosessioikeuden peruskäsitteitä. Asiavaltuus antaa oikeutta hakevalle asianosaisen aseman: hän pystyy viemään asiansa tuomioistuimen käsiteltäväksi ja saa siihen ratkaisun. Ellei hänellä ole asiavaltuutta, hänen kanteensa jätetään tutkimatta. Lisäksi hänen katsotaan hävinneen asiassa. Vaikka asiavaltuus on oikeutta hakevalle tärkeä, prosessilaeissa siitä ei ole yleisiä säännöksiä. Monien soveltamistilanteiden varalta on sen sijaan lukuisia erityissäännöksiä, jotka kuitenkaan eivät tuo selvyyttä tulkintaan. Asiavaltuus sisältää tästä syystä rakenteellisen ristiriidan. Yhtäältä tuomioistuimen pitäisi pystyä heti oikeudenkäynnin alussa sanomaan, onko kantajalla asiavaltuus. Toisaalta monissa tilanteissa asiavaltuus on tosiseikoiltaan tai oikeudelliselta perusteeltaan niin epäselvä, että asiaa on käsiteltävä pitkälle, jotta asiavaltuudesta kyetään päättämään. Tämä taas johtaa tunnettuun paradoksiin: asia tutkitaan, jotta nähdään, tuleeko se tutkia. Paradoksiin on haettu ratkaisuja, mutta ne joko eivät toimi tai ovat tehokkaita vain osa-alueilla. Tässä kirjassa analysoidaan asiavaltuuden käsitettä, asiavaltuuden tavoitteita, asiavaltuuden määräytymisen perusteita sekä asiavaltuuden käsittelyä oikeudenkäynnissä. Huomiota kiinnitetään muutostrendiin: asiavaltuus näyttää, muiden asiaan liittyvien prosessinedellytysten tapaan, hitaasti murenevan.

Aim: this study aims to assess the alterations in the START vascular stiffness index and identify potential risk factors influencing these changes in patients with coronary artery disease (CAD) one year following coronary artery bypass grafting (CABG). Patients and Methods: the study included patients with CAD who underwent CABG at the Research Institute of Complex Problems of Cardiovascular Diseases in Kemerovo. Preoperative measurement of peripheral artery stiffness was performed using the VaSera VS-1000 sphygmograph (Fukuda Denshi, Japan). The cardio-ankle vascular index (CAVI) and the novel domestic haSTART arterial stiffness index were determined using brachial-ankle pulse wave velocity (baPWV). These measurements were repeated one-year post-CABG, and the changes were analyzed. The final cohort consisted of 197 patients, divided into two groups: group I included patients with a reduction in the haSTART index (n=107), while group II comprised those with an increase (n=90). Results: the mean patient age was 59.4±8.3 years. Group II had a higher percentage of male patients (82.2% vs. 68.2%, p=0.024). Psychological distress predisposition was observed in 32.7% of group I and 52.2% of group II (p=0.006). Calcium channel blocker use was noted in 26.2% of group I versus 12.2% in group II (p=0.013). Group I also had a higher overall number of consultations during the follow-up period (p=0.013). Significant increases in baPWV and CAVI were found in group II (p<0.001). Factors associated with an increased haSTART index at one-year post-surgery included age (r=0.407, p<0.001), diabetes mellitus (r=0.181, p=0.048), multifocal atherosclerosis (r=0.145, p=0.04), heart failure (r>0.217, p=0.009), a higher CABG risk according to EuroSCORE (r≤0.30, p<0.001), and a predisposition to psychological distress (r=0.171, p=0.02). Conclusion: time-domain measurement of vascular stiffness via the haSTART index is valuable for assessing treatment efficacy and provides crucial prognostic information for patients with CAD in clinical settings.

Aim: to study the activity of pro-inflammatory cytokine interleukin 6 (IL-6) and determine its significance as a marker of emerging cardiometabolic risks in adolescent male patients with obesity, taking into account clinical and biochemical manifestations of metabolic syndrome (MS). Patients and Methods: 96 adolescent male patients aged 16–18 years with obesity of class 1–3 were examined. IL-6 levels, serum lipidogram,basal and glucose-stimulated concentrations of insulin during a standard oral glucose tolerance test were determined in all patients. Results and Discussion: in patients with obesity, the IL-6 content was higher than in healthy adolescents (p=0.03) in the absence of a significant association with BMI. Besides, the IL-6 content increased in individuals with high insulin resistance (HOMA-IR index >5.0) versus the patients whose index value was lower (p=0.04). The IL-6 count in adolescents with blood triglycerides >1.7 mmol/l was higher than in patients with normal concentrations (p=0.023). Adding that, a significant increase in IL-6 content was shown in adolescents with hypertension (p=0.04). MS with three or more signs in accordance with the International Diabetes Federation (IDF) criteria was diagnosed in more than half of the surveyed adolescents with obesity. IL-6 levels were significantly elevated in patients with MS signs, especially in those with its complete form. An increase in IL-6 production in adolescents with obesity correlated with the stages of dyslipidemia, induced hyperinsulinemia and hypertension, which allows to use this indicator as a marker of emerging MS.

The Vertex-Edge Locating Roman Domination of Some Graphs
Authors: Akwu Abolape Deborah , Agbaji Comfort
Published: October 2024

In this paper, we introduce the concept of vertex-edge locating Roman dominating functions in graphs. A vertex-edge locating Roman dominating (\({ve} - {LRD}\)) function of a graph \(G = {(V,E)}\) is a function \(f:{{V{(G)}}\rightarrow{\{ 0,1,2\}}}\) such that the following conditions are satisfied: (i) for every adjacent vertices \(u,v\) with \({f{(u)}} = 0\) or \({f{(v)}} = 0\), there exists a vertex \(w\) at distance \(1\) or \(2\) from \(u\) or \(v\) with \({f{(w)}} = 2\), (ii) for every edge \({uv} \in E\), \({max{\lbrack{f{(u)}},{f{(v)}}\rbrack}} \neq 0\) and (iii) any pair of distinct vertices \(u,v\) with \({f{(u)}} = {f{(v)}} = 0\) does not have a common neighbour \(w\) with \({f{(w)}} = 2\) . The weight of \(ve\)-LRD function is the sum of its function values over all the vertices. The vertex-edge locating Roman domination number of \(G\) denoted by \(\gamma_{{ve} - {LR}}^{P}{(G)}\) is the minimum weight of a \(ve\)-LRD function in \(G\). We proved that the vertex-edge locating Roman domination problem is NP complete for bipartite graphs. Also, we present the upper and lower bonds of \(ve\)-LRD function for trees. Lastly, we give the upper bounds of \(ve\)-LRD function for some connected graphs.

Published: October 2024

Over recent years, the issue of sustainability has become a popular term in the research arena and policies. It appears that one of the best strategies to ensure sustainability of NGOs is through effective corporate governance. This exploratory study was conducted to identify the role played by corporate governance mechanisms in the sustainability of elderly care centres operated by Malaysian NGOs. This study adopted a semi-structured interview technique to achieve a better and more in-depth understanding. Ten (10) elderly care centres operated by NGOs in Kuala Lumpur and Selangor; Malaysia participated in this study. The findings indicated that corporate governance practices played a significant role in improving the sustainability of Malaysian elderly care centres run by NGOs and it was critical for these organisations to assess the corporate governance practices they employ in the management of their day-to-day operations to achieve better performance. This study can provide guidance to regulators in enhancing their regulatory framework so that it is more in line with the systems adopted by NGOs in other more developed countries. This study also recommended that boards of NGOs adopt corporate governance best practices to enhance the sustainability of their organisations.

The API Model of Strategic and Tactical Marketing Thinking for Management Education
Authors: Martinović Maja
Published: October 2024

This paper addresses the need to improve marketing education for managers, particularly those from non-economic fields. Research indicates that effectively transferring marketing knowledge involves translating theory into practice, connecting with research, addressing diverse participant needs - relevance, and employing innovative working methods. The study was conducted on a sample of 142 MBA program participants from various non-economic backgrounds, who were presented with and explained the API (analysis, planning, implementation) model of strategic marketing thinking and tactical actions. The results show that visual presentation is a good method for displaying the connections in the model and can even change the perception of marketing. It is important to consider the participants’ prior knowledge of marketing since they show differences in the perceived clarity and usefulness of the model. After being introduced to the model, there are statistically significant differences in the changed perception of its clarity and usefulness among different groups based on their level of prior marketing knowledge. The findings suggest that the API model aids in comprehending environmental complexities and developing effective strategies and tactics, benefiting participants, employers, educators, and society overall.

Published: October 2024

This research aims to investigate the influence of Electronic Customer Relationship Management (e-CRM), hedonic browsing, and utilitarian browsing on e-satisfaction and e-loyalty in online shopping in Indonesia. To investigate the associations between these variables, Structural Equation Modeling (SEM) analysis was performed using a quantitative study methodology and survey data from 962 respondents. The findings show a strong correlation between utilitarian browsing and e-satisfaction and e-loyalty, hedonic browsing and e-satisfaction, and e-satisfaction and e-loyalty. Nevertheless, there was no statistically significant correlation discovered between e-CRM and e-loyalty or e-satisfaction. The results highlight the significance of giving equal weight to hedonic and utilitarian elements of the virtual buying encounter in order to augment client contentment and allegiance. Furthermore, even though the findings did not conclusively confirm the efficacy of e-CRM techniques in affecting customer outcomes, managers ought to be aware of their potential influence on cultivating enduring customer connections.
The Moderating Roles of Environmental Awareness and Product Knowledge on the Impact of Marketing Mix Elements on Purchase Intention
Authors: Tripopsakul Suchart
Published: October 2024

The purpose of this study is to examine the moderating effects of environmental awareness (EA) and product knowledge (PK) on the relationship between marketing mix elements and the purchase intention of electric vehicles (EVs) in Thailand. Based on a quantitative research design, 253 samples of Thai respondents aged 20 and above were collected via an online questionnaire as a research tool. Structural Equation Modeling (SEM) analysis was used to analyze the proposed hypotheses. The results indicate that all four marketing mix elements, which are product attributes, pricing strategy, distribution channels (place), and promotional activities, significantly influence the purchase intention of electric vehicles. Product attributes (b = 0.523) have the strongest impact on purchase intention, followed by pricing strategy (b = 0.501), distribution channels (place) (b = 0.477), and promotional activities (b = 0.334) respectively. The results of moderation analysis reveal that environmental awareness significantly moderates the effect of product attributes (b = 0.412) and pricing strategy (b = 0.305) on purchase intention but is not found in the relationships of distribution channels (place) and promotional activities toward purchase intention. Additionally, consumer product knowledge of EVs was found to significantly and negatively moderate only the influence of promotional activities (b = -0.343) on purchase intention. In other words, potential consumers who possess higher EV knowledge seem to be less influenced by promotional activities in their decision to buy EVs. These findings highlight the importance of integrating environmental concerns and EV product knowledge into the firm’s marketing strategies to boost EV adoption in emerging countries. The implications and recommendations will be discussed in the paper.

Published: October 2024

This study explores factors influencing entrepreneurial development among women microentrepreneurs in Malaysia. Using self-administered questionnaires distributed to 50 participants, the research examined four key factors: family support, business prospects, sociocultural factors, and government support, with entrepreneurial development as the dependent variable and perception of success as a mediator. The data was analyzed using SmartPLS software. Results indicated that most variables had reliable Cronbach Alpha values, though issues with discriminant validity were found. The structural model showed substantial explanatory power, and most path coefficients indicated positive relationships, except for the link between government support and entrepreneurial development. However, only one hypothesis was accepted, revealing that socio-cultural factors significantly influence entrepreneurial development through the perception of success. The study suggests that future research should focus on specific sectors within microenterprises and include a larger sample size for a broader understanding of women’s economic contributions. This research provides valuable insights for policymakers aiming to enhance support for women microentrepreneurs in Malaysia.

Malignant hyperthermia (MH) is a rare, potentially fatal genetic disorder characterized by an unexplained elevation of expired carbon dioxide despite increased minute ventilation, muscle rigidity, and rhabdomyolysis, hyperthermia, tachycardia, acidosis, and hyperkalemia. It can be triggered by many pharmacological agents such as potent inhalation agents (halothane/ isoflurane/ sevoflurane/ desflurane), the depolarizing muscle relaxant (succinylcholine), and extreme physiological conditions such as vigorous exercise and working excessively in a hot and dry environment. Prompt and early recognition of the condition and rapid initiation of treatment measures are necessary to salvage the patient. Since MH is commonly encountered in the operating room or early postoperative period, anesthetists and surgeons need to keep themselves updated regarding the same. This review article aims to summarize our understanding of MH's pathophysiology, current diagnostics, management, and treatment strategies, along with a brief review of literature of published cases in Indian Subcontinent.

The problem of heat conduction in nonlinear media reduces to solving boundary value problems for nonlinear heat conduction equations, where the coefficients of the equation or the function of the power of heat sources depend on temperature according to some law. Among the numerical methods for solving problems for nonlinear equations of mathematical physics, one can distinguish finite difference methods, finite element methods, variational and projection methods, as well as iterative methods. Among the latter group, the two-sided approximation method is particularly attractive due to its ability to provide a convenient estimate for the error of the approximate solution and to prove the existence of a solution to the original problem. The theory of linear partially ordered spaces was developed by L. V. Kantorovich in the second half of the 1930s. Further development of this theory is associated with the works of M. A. Krasnosel’skii, H. Amann, V. I. Opojtsev, N. S. Kurpel, B. A. Shuvar, A. I. Kolosov etc. The aim of this article is to develop a two-sided approximation method based on the use of Green's functions for solving the first boundary value problem for a one-dimensional nonlinear heat conduction equation and to investigate its performance when solving test problems. To achieve this goal, the unknown function was replaced, and the boundary value problem was reduced to a Hammerstein integral equation, which was considered as a nonlinear operator equation in a partially ordered Banach space. Conditions for the existence of a unique positive solution to the problem and conditions for two-sided convergence of successive approximations to it were obtained. The developed method was implemented in software and tested on solving test problems. The results of the computational experiment are illustrated with graphical and tabular information

Integral nonlinear models are used to create mathematical models of the human oculo-motor system (OMS). These models take into account both inertial and nonlinear properties of the objects under study. To obtain empirical data for model construction, experimental studies are conducted with OMS using «input-output» data. Visual stimuli are used as test signals, displayed on a computer monitor at various distances from the starting position, which formally corresponds to the action of step signals with varying amplitudes on the object of study. In this process, the responses of the OMS are recorded using innovative eye-tracking technology. Mathematical models in the form of Volterra series and polynomials are employed for computer modeling of the OMS. The aim of this research is to analyze the accuracy of OMS identification as multidimensional transient functions based on eye-tracking data, examining the dependency of computation errors for models of different orders on the amplitudes and quantities of the test signals used. The subject of the study includes various methods for identifying OMS, algorithms, and Python-based software tools for computing the dynamic characteristics of OMS using eye-tracking technology. The research explores identification methods: compensation, approximation, and least squares methods. The accuracy of the linear, quadratic, and cubic OMS models is evaluated. The most accurate models, constructed from real experimental data, are found to be quadratic or cubic OMS models obtained using the least squares method with three test signals.

The efficiency of real-time systems makes them applicable in various fields by utilizing protocols for data transmission. Well-known transport layer protocols include Transmission Control Protocol (TCP) and User Datagram Protocol (UDP), which facilitate such transmission. However, there are challenges in using these protocols [1] in real-time systems where data rapidly changes during application execution. Exclusively using one of these protocols adversely affects the stable operation of the application and increases the risk of data obsolescence. The objective of this work is to develop and model a data transmission subsystem for real-time systems that utilizes the Reliable UDP (RUDP) protocol [2] for data synchronization. Implementing the RUDP network protocol in the subsystem addresses network issues such as delay, packet loss, and duplication in the most optimal way during real-time data synchronization between sensors and the server, reducing the load on bandwidth. The tasks of the developed subsystem, consisting of a server and a client, include: reading user-specified system data, reliable message transmission between the server and the client using sockets for RUDP protocol operation, ensuring the most optimal message delivery in case of packet loss, subsystem operation modeling compared to well-known UDP and TCP protocols. The simulation results reveal that the maximum time spent by the subsystem is 2.03 seconds for the RUDP protocol and 6.22 seconds for the TCP protocol. Therefore, RUDP is recommended for data transmission in the future. In the event of message loss, retransmission occurs exponentially, calculated using the proposed formula. If the initial transmission occurs immediately, subsequent times exponentially increase but remain collectively less than the transmission time for the TCP protocol.
