Objetivo: Analisar a satisfação de pessoas idosas com o atendimento na Atenção Primária à Saúde em uma cidade de médio porte do Brasil. Método: Estudo transversal, com amostragem probabilística de 162 pessoas idosas, em Campina Grande, Brasil, no ano de 2017. Os dados foram coletados com instrumento contendo variáveis sociodemográficas, de acesso e utilização de serviços de saúde e de satisfação com o atendimento, aplicado de forma presencial na residência dos participantes. Realizaram-se análises univariada e múltipla, por meio de Regressão de Poisson, com auxílio do Software Stata® ,considerando um intervalo de confiança de 95% e significância estatística quando p < 0,05. Resultados: A taxa de satisfação da pessoa idosa com o atendimento naAtenção Primária à Saúde foi de 70% (IC: 63% – 77%). A estimativa ajustada foi 64% maior quando o usuário obteve consulta com um profissional de saúde na última vez que procurou atendimento (aRP = 1,64 [comparado com quem não obteve]; IC: 1,11 – 2,43; p = 0,013) e 21% maior quando recebeu visita domiciliar de um profissional de saúde nos últimos 30 dias (aRP = 1,21 [comparado com quem não recebeu]; IC: 1,02 – 1,45; p = 0,029). Entretanto, foi 36% menor quando os participantes relataram espera em fila superior a duas horas no último atendimento (aRP = 0,64 [comparado com espera de até duas horas]; IC95: 0,43 – 0,96; p = 0,030). Conclusão: A satisfação de pessoas idosas com o atendimento na Atenção Primária à Saúde é consistente com achados disponíveis e está associada a aspectos de acesso e utilização dos serviços, como a obtenção de atendimento diante de uma necessidade manifesta, o recebimento de visitas domiciliares e o tempo de espera em fila para ser atendido.

The “Heretics” Hermeneutics: Bosnia and Balkan Bogomils in the Mirror of Modern Hungarian Literature As Potential(Borrowed?) Theaters of Multidimensional Orientalism
Authors: Ivanyi Marton
Published: February 2025

In Hungary, situated in Central-Eastern Europe, the historical and cultural investigation of its relationship with the Balkans holds particular relevance due to the country’s unique and shifting historical position. Hungary has experienced distinct phases in its history: as a medieval middle power, later as a territory under Austrian rule, and subsequently as a state-forming entity within the Austro-Hungarian Monarchy. This progression has shaped Hungary’s perception of its neighbors and its role within European ideological currents, particularly those influenced by Orientalist discourses. The portrayal of the Bosnian (primarily identified – and subject to historical debate – as "Bogomils")in Hungarian historical literature is a compelling case in point. While not explicitly tied to imperial expansionist ambitions, such representations reflect European tendencies of “Othering,” where the “heretics” – often dismissed as heretics, tribal, or primitive – were situated in opposition to Western or Catholic norms. This dynamic was further complicated by Hungary’s intermediary status between Western Europe and the Balkans, creating a cultural and epistemological space that was neither fully “Orientalized” nor wholly part of the Western Occident. Hungary’s historical entanglement with the Balkans, therefore, offers a nuanced vantage point from which to examine Orientalist tendencies. These explorations are further elevated by the ideological debates surrounding the continuity between the medieval Bogomils and the later Bosnian Muslim population. The widely challenged notion that the Bogomils would have been "predecessors" of Bosnian Muslims adds another layer of ideological tension, particularly within critiques of Islam, which often bear a degree of ideological saturation. At first glance, Hungary’s portrayals of the Bosnian Christians cannot be isolated from broader European perceptions of Islam, where the historical Crusades, medieval animosities, and Enlightenment-era Orientalist narratives intersect. However, the Hungarian corpus itself rarely engages with the Bogomils as proto-Muslims, a narrative more prevalent in earlier Western and later Balkan discourses. Instead, Hungarian representations tend to emphasize the "sect"’s heretical nature, aligning more closely with medieval historiographical traditions than with ideological critiques of Islam. In this context, Hungary’s role as both a subject and an actor in these historical frameworks underscores the relevance of analyzing its cultural and literary portrayals of the Balkans and the Bosnia’s legacy. This dual position allows for critical insight into the hierarchical nature of Orientalism while also accounting for Hungary’s unique historical trajectory and its layered relationship with both “East” and “West.”
The Political Movement for the Republic of Kosovo – July 2, 1990
Authors: Krasniqi Agon
Published: February 2025

The purpose of writing this paper is to provide new information on the political situation in Kosovo during the year 1990, with a particular focus on the political movement in Kosovo for the Republic of Kosovo. The analysis of the July 2nd event holds significant importance for Albanian historiography, marking the first major step by Albanians of Kosovo in opposing the March 1989 constitution, which had revoked Kosovo's autonomy a status initially achieved through the 1974 constitution. As a result, Kosovo was reclassified as a subject under the Serbian Republic. My study's focus on the July 2nd event aims to examine archival sources and interpret them using an analytical method, to offer a perspective on one of Kosovo’s most pivotal events in the 1990s. The objectives of the paper will focus on the political situation in Kosovo following the abolition of Kosovo's autonomy, which influenced the political developments in Kosovo during 1990. The focus will then shift to the constitutional declaration of July 2nd, the delegates, the developments during the declaration of the republic, the decisions made during the session, as well as the developments after the July 2nd event and the international reactions. This work relies heavily on archival resources from the State Agency of Kosovo Archives (ASHAK), the Municipal Archive of Kaçanik, the "Sadik Tafarshiku" Library, and the "Rilindja", "Bujku", "Bota Sot" newspapers. In addressing this topic, my focus has been on uncovering archival sources and interpreting them. Based on this approach, I will present various archival documents, including the minutes from July 2, 1990—a historical event symbolizing the declaration of Kosovo’s republic within the framework of the Socialist Federal Republic of Yugoslavia (SFRY). This act demonstrates Kosovo’s reaction against the 1989 constitution, which revoked its autonomy, indicating Kosovo’s position as equal to the other republics within the SFRY. This reaction was marked in the hall of the Kosovo Assembly on July 2, 1990, with the participation of 114 delegates; by July 3, the final delegate was also present, bringing the total to 115 delegates who signed the declaration for Kosovo to become the seventh republic of Yugoslavia. The reason for the delay of the 115th delegate refers to extraordinary events and difficult conditions for attending the session. Thus, with the 115 signatures of the delegates of the Kosovo Assembly, Kosovo was declared a Republic of Yugoslavia, which was a success of the political movement, a success that surpassed even the declaration of autonomy in 1974.Through the use of archival sources and their scientific interpretation, we will draw key conclusions regarding the topic, helping to understand the role and significance of the July 2nd event in Kosovo’s history.
The Balkans Politics, History and Society
Authors: Abdula Sevba
Published: February 2025

The world is clearly facing significant crises. Issues such as global security, cli- mate, trade, democratisation, law, epidemics, failed states, terrorism,are likely to negatively affect humanity and civilisation. In other words, it is obvious that we are on the eve of a period that will narrow welfare and development. His- torically the Balkans have been affected and shaped according to the materi- al and spiritual prosperity periods of humanity throughout history. It does not seem possible to separate the major crises in the region from world politics, his- tory, and transformation. It is evident that the great expectations and positive atmosphere created by the millennium have led to a partial expansion, coope- ration and progress in institutional culture in the Balkans in the last quarter of a century. Since the long 19th and 20th century produced a period of divergence in the Balkan countries, peoples or the region as a whole, convergence with the current world culture and institutions will take time. It is clear that research and knowledge production on the history, sociology, economy and politics of the re- gion will increase the momentum of this convergence and make a great contri- bution to the future of the region in this sense.
The study of Balkan history generally includes the region’s rich and complex history, its ethnic and religious diversity, in order to understand the complexity created by the nation-state building processes of the last two centuries and the dissolution of empires. In the last 20 years, these nationalist and state-centred studies have been joined by a growing body of research on culture, women, micro-history, migrations, biographies, social groups and economic structures. What the region needs is the institutionalisation of a rich research culture and the construction of a society that will open the door to all forms of production and surplus value.

Published: February 2025

This article aims to analyze the reduction of the age of criminal responsibility, a highly controversial topic given the increasing crime rates involving adolescents, alongside a growing prison population that exceeds incarceration capacity. The precarious living conditions in overcrowded and unsanitary penal institutions reinforce the argument that it is the State's duty to implement public policies to prevent issues such as school dropout, which often leads minors into the world of crime. Research was conducted in books by various authors and articles published online, presenting arguments both in favor of and against lowering the age of criminal responsibility and its implications.

Published: February 2025

Lead is often referred to as lead or plumbum. Lead (Pb) is a heavy metal that can cause poisoning until it can accumulate in the human body. The process of entering Pb into the body can go through several pathways, namely through food and drink, air and penetration or penetration of the membranes or layers of the skin. Hair is one of the bioindicators of heavy metal pollution because in the hair there is a sulfhydryl group that can bind lead. This research aims to determine the lead metal content in the hair of the Mr X public transportation driver on the Medan Amplas - Medan Helvetia route in 2024. A wet destruction method validation test has been carried out for the determination of lead (Pb) levels in the hair. Wet destruction using HNO3 and HCl. The analysis of the lead content of the destruction was carried out with an Atomic Absorption Spectrophotometer (SSA). The research results show that the highest Pb Lead level in hair is 24,000 ppm with a service life of 27 years, and the lowest Pb Lead level in hair is 0,400 ppm with a working period of 3 years.

Published: February 2025

The study focused on the purpose of finding out about caesarean section delivery is the last alternative to save the mother and fetus when normal delivery is not possible. The increase in caesarean sections worldwide has become a major public health problem, so there needs to be supervision to reduce the number of caesarean sections that are considered unnecessary, one of which is through the classification. The existence of health insurance for the Indonesian people, including BPJS which covers the cost of caesarean operations, allows for an increase in the incidence of caesarean sections. The purpose of the study was to analyze the financing status of the BPJS based National Health Insurance (JKN) program for caesarean section deliveries. This study used quantitative research with a cross sectional, the research sample was mothers who gave birth by caesarean section who used the BPJS National Health Insurance (JKN). This study discusses reporting for one year in 2023, participants who used BPJS national health insurance for caesarean section deliveries were 1117 participants. With the income of BPJS caesarean section services with hospital rates in UHC (Universal Health Care) 2019, will be implemented, while BPJS health according to Indonesia Law number 24 of 2011 is appointed by the government as a health insurance management agency. Data results show that the incidence of caesarean section using National Health Insurance (JKN) is still very high in hospitals. The management of hospitals needs to calculate service costs using unit costs so as not to experience a deficit and anticipate future management.

The Relationship Between Gastroesophageal Reflux Disease (Gerd) and Sleep Quality in Medical Faculty Students of Indonesian Muslim University Class of 2021. Gastroesophageal Reflux Disease (GERD) is a chronic gastrointestinal disorder characterized by the regurgitation of stomach contents into the esophagus, causing symptoms such as heartburn, regurgitation, sore throat, and cough. GERD can worsen sleep quality, contributing to sleep disorders. This study aims to examine the association between GERD and sleep quality among medical students at Indonesian Muslim University Class of 2021. This study emploved a descriptive analytics desing with a cross-sectional approach, and the sample was selected through total sampling. The chi-square test was applied to analyze the association between GERD and sleep quality with a significance level of p < 0.05. Among 274 respondents, 45 (16.4%) had GERD, while 229 (83.6%) did not. Additionally, 42 (15.3%) had good sleep quality, whereas 232 (84.7%) had poor sleep quality. Statistical analysis showed a p-value = 0.027, indicating a significant association between GERD and sleep quality (p < 0.05). The findings suggest that students with GERD are at a higher risk of experiencing poor sleep quality. These results highlight the need for preventive measures and interventions to improve sleep quality in students suffering from GERD.

Published: February 2025

The purpose of the article was to investigate seven case-studies of wrong implementations of gamification in companies. Examples included: Microsoft Ribbon Hero, Volkswagen Fun Theory, Google News Badges, Nike + Challenges, Foursquare’s Project, Yahoo Answers Points and DevHub Coding Website. We analyzed the reasons of their failure and tried to generalize the findings to create a comprehensive matrix of mistakes that one should avoid while introducing gamification into the project. The article fills the gap in literature concerning failures in gamification. There are very few publications discussing this issue and we believe that added new observations into this research matter. The research method employed in the paper was based on critical analysis of gamification projects and finding mistakes in the implementation process. As a conclusion, we found out that the main problems of failed gamifications included: improper design of the game mechanics, ignoring different types of player personalities, and finally, insufficient alignment of the content with real-world goals of players. The conclusion of the paper is that different people enter the game for different reasons, but every player has a specific goal, and this goal must be achieved by the gamified project.
Stability or change? The long-term construction of ECEC rationales on the governmental and parliamentary levels in Finland
Authors: Lundkvist Marina , Nygård Mikael
Published: February 2025

In recent years, Finnish legislation on Early Childhood Education and Care (ECEC) has been reformed several times as a way of increasing quality and enhancing children’s learning and wellbeing. However, little research has been conducted on what this means in terms of ECEC rationales on a national level and how such rationales have developed over time. Therefore, the aim of this article is to analyse the political construction of ECEC rationales over time by conducting qualitative content analyses of government bills and minutiae from parliamentary debates relating to three recent reforms (in 2015, 2018 and 2021). We argue that although the discourse on ECEC rationales is mainly characterised by stability, there are also elements of change. Rationales relating to equality, lifelong learning and children’s rights have remained more or less unchanged, while rationales relating to quality ECEC and parental involvement in ECEC have received a more prominent position since 2018.

Authors: Silva Flaviane de Lima Pereira , Coutinho Diogenes José Gusmão
Published: February 2025

O HIV, ou vírus da imunodeficiência humana, é responsável pela AIDS e ataca o sistema imunológico, especialmente os linfócitos T CD4+. Em 2018, foi introduzida a PrEP (profilaxia pré-exposição), uma combinação de medicamentos (tenofovir e entricitabina) que bloqueia a infecção pelo HIV, sendo eficaz para pessoas em alto risco, como homens que fazem sexo com homens, pessoas trans e profissionais do sexo. A PrEP é disponibilizada gratuitamente pelo SUS, mas a prescrição por profissionais de saúde é limitada devido à falta de conhecimento e prática. Este estudo visa avaliar o conhecimento desses profissionais sobre a recomendação da PrEP, destacando a importância da adesão e da comunicação eficaz para a prevenção do HIV. A pesquisa foi realizada com médicos, enfermeiros e farmacêuticos do estado de Sergipe, no mês de setembro e outubro de 2024. OBJETIVO: Avaliar o conhecimento dos profissionais de saúde sobre o uso da PrEP no estado de Sergipe. MÉTODOS: A pesquisa foi realizada através de um instrumento de coleta de dados constituído por uma série de perguntas, que devem ser respondidas online e sem a presença do entrevistador. Esse questionário foi aplicado através do Formulário Google, uma ferramenta digital que permite alcançar o máximo de participantes do Estado de Sergipe. RESULTADOS: No total de 54 profissionais que responderam a pesquisa 96,3% já ouviram falar sobre a PrEP, porém 61,1% responderam que não tem conhecimento suficiente para prescrever a prevenção e 81,1% responderam que precisam de treinamento para realizar a prescrição.  CONCLUSÃO:  De acordo com as respostas dos participantes, muitos profissionais sabem o que é a PrEP, mas não se sentem preparados para indicar a prevenção para os usuários por falta de conhecimento das drogas utilizadas e treinamentos para a sua utilização correta dos fármacos e suas possíveis reações adversas.
Evaluation of Ozone and its Precursors using the Multi-Scale Infrastructure for Chemistry and Aerosols Version 0 (MUSICAv0) during the Michigan-Ontario Ozone Source Experiment (MOOSE)

Abstract. Surface ozone (O3) in Southeast Michigan (SEMI) often exceeds U.S. National Ambient Air Quality Standards, posing risks to human health and agroecosystems. SEMI, a relatively small region in the state of Michigan, contains most of the state’s anthropogenic emission sources and more than half of the state’s population, and is also prone to long-range and transboundary pollutant transport. Here, we explore the distribution of O3 and its precursors, such as nitrogen oxides (NOx) and volatile organic compounds, over SEMI during the summer of 2021 using the chemistry-climate model, MUSICAv0 (Multi-Scale Infrastructure for Chemistry and Aerosols, Version 0). Using the regional refinement capabilities of MUSICAv0, we created a custom grid over the state of Michigan of 1/16° (~7 km) to better understand the local-scale impacts of chemical and dynamic complexity in SEMI and compared it with a grid with 1/8° (~14 km) resolution over the contiguous United States. Model simulations are evaluated using a comprehensive suite of observations from Phase I of the Michigan-Ontario Ozone Source Experiment (MOOSE) field campaign. MUSICAv0 with higher horizontal grid resolution showed excellent skill in capturing peak O3 concentrations, but showed larger variation in the simulation of O3 precursors (e.g., NOx, HCHO, isoprene). In addition, we implemented a diurnal cycle for anthropogenic nitric oxide (NO) emissions, which is generally not included in global models. As a result, modeled nighttime O3 was improved because of lower NOx concentrations during the night. This work shows that when conceptualizing models in urban regions, it is important to consider a combination of high horizontal resolution and the diurnal cycle of emissions, as they can have important implications for the simulation of secondary air pollutants.
Quantifying controls on rapid and delayed runoff response in double-peak hydrographs using Ensemble Rainfall-Runoff Analysis (ERRA)
Authors: Gao Huibin , Pfister Laurent , Kirchner James W.
Published: February 2025

Abstract. Double-peak hydrographs are widely observed in diverse hydrological settings, but their implications for our understanding of runoff generation remain unclear. Previous studies of double-peak hydrographs in the extensively instrumented Weierbach catchment have linked he first peak to event water and the second, delayed and broader peak to pre-event water. Here we use Ensemble Rainfall-Runoff Analysis (ERRA) to quantify how precipitation intensity and antecedent wetness influence groundwater recharge and double-peak runoff generation at the Weierbach catchment (Luxembourg). The spiky first peak can be attributed to a rapid response directly linking precipitation to streamflow via near-surface flowpaths. Relative to this first peak, the second peak is delayed (peaking ~1.5 days after rain falls), lower (~1/3 the height of the first peak), and broader (declining to nearly zero in ~10 days), and can be attributed to a groundwater-mediated pathway that links precipitation, groundwater recharge, and streamflow. The sum of these two runoff responses quantitatively approximates the whole-catchment runoff response. Under wet conditions, the first peak increases nonlinearly (particularly above precipitation intensity of 2 mm h-1) and the second peak becomes higher, narrower, and earlier with increasing precipitation intensity. Under dry conditions, the first peak increases nonlinearly with precipitation intensity (particularly above 4 mm h-1), and groundwater recharge also responds to precipitation, but no clear second peak occurs regardless of precipitation intensity. The lack of a second peak under dry conditions plausibly arises from groundwater loss to evapotranspiration and from limited connectivity between groundwater and the stream, rather than from a lack of groundwater recharge. Almost no runoff response occurs at precipitation intensities below ~0.8 mm h‑1 under wet conditions and ~1.5 mm h‑1 under dry conditions. After a precipitation-related threshold that initiates the first peak and a catchment wetness threshold that initiates the second peak, higher precipitation intensities amplify the first peak nonlinearly and trigger a larger and quicker second peak.

Abstract. To enhance the vibration isolation functionality of the seat suspension system, particularly in the context of magnetorheological (MR) seat dampers, a pioneering semi-active controller integrating an adaptive neuro-fuzzy inference system (ANFIS) and active disturbance rejection control (ADRC) was devised. Firstly, the Bouc–Wen model was employed to establish the dynamic model of the damper based on experimental data, thereby ensuring an accurate description of the actual physical behaviours. Subsequently, the ANFIS technology was employed to develop an inverse model, which detailed the structural design and training process of the inverse model. This resulted in the achievement of precise prediction and control of the damper behaviour. Ultimately, the ANFIS inverse model was integrated with the designed ADRC controller to create an innovative control scheme for the seat suspension system of a two-degrees-of-freedom dynamic model, and a simulation analysis was conducted. The simulation results demonstrate that the root-mean-square (rms) value of the vertical vibration acceleration of the ADRC-controlled suspension system decreased by 68.9 % and 34.4 % in comparison to proportional–integral–derivative (PID) control and passive control, respectively. The rms value of the dynamic disturbance of the ADRC-controlled suspension system decreased by 50.0 % and 28.6 % compared to PID control and passive control, respectively. This verifies the performance of the proposed controller, particularly in the precise control of damping force, demonstrating outstanding effectiveness.
Le Bu sous domination allemande : un essai de bilan démo-économique
Authors: Ngayimpenda Evariste
Published: February 2025

This chapter attempts a demographic and economic assessment of the short period of German colonisation of Burundi (1896–1916), with particular emphasis on Burundi's involvement in the World War I. The chapter shows that military expeditions were accompanied by numerous cattle raids and the burning of huts and fields, both to weaken resistance and to provide a material and logistical base for the colonial administration and missionaries. Likewise, the capture of prisoners provided free and permanent workforce for both types of authority. Stripping the rebel chiefs of their material and territorial base undermined their authority, while the transfer of a share of the booty served to reward the collaborating chiefs. Finally, the consolidation of colonial and missionary power became a source of impoverishment for the population, as the number of beneficiaries of benefits in kind and in workforce multiplied. This situation was exacerbated from mid-1914 to 1917–18, with Ruanda-Urundi serving as a battleground between German forces and a Belgian-British coalition that drove the Germans out of their East African possessions.

The main objective of the work is to study the influence of the porous layer on the intensity of heat transfer during flow boiling in mini- and microchannels with localized heating from the wall side (heater size 3x3 mm2) with a channel width and length an order of magnitude larger. The following problems were solved to achieve these goals. A technology was created for forming various porous coatings on a heater based on Nickel powder with a characteristic grain size of about 60-100 μm. As a result, three different thin (150 μm scale) porous coatings were obtained: Nickel (100% Ni) and two bimetallic coatings containing copper or zinc powders (80% Ni + 20% Cu, 50% Ni + 50% Zn). Systematic studies of heat transfer during boiling with non-uniform heating in mini- and microchannels with a height of 0.55 to 2.0 mm with subcooling water were carried out. The experiments were carried out with intensive heating from the wall side, up to 1.6 kW/cm2. There are established facts that are important results. The values of heat transfer coefficients and critical heat flux on porous surfaces are significantly (up to 3 times) higher than for a smooth surface. The values of critical heat flux reached 1.2 kW/cm2, and the values of heat transfer coefficient reached 100 kW/(m2 K). The significance of the obtained results is that the features of localized heating are underestimated but are important in modern multi-chip electronic systems and promising power plants. This will allow achieving the required scale of heat exchange parameter values when developing highly efficient heat exchange systems for modern microelectronics and power engineering.

The paper is devoted to the problem of purification of gaseous fuels used in thermal power plants. It is not uncommon for stations to use gaseous waste from petrochemical enterprises as an ad-ditive to the main fuel as part of a resource-saving policy. However, natural gas and gaseous waste need to be pre-cleaned of sulfur compounds to reduce the operating load on equipment and reduce the negative impact on the environment. The purpose of this article is to develop and justify the choice of a sorption material with a high sulfur content and physical characteristics that meet the requirements of GOST. This goal is achieved through the implementation of the following tasks: analysis and selec-tion of components of sorption materials based on TPP water treatment sludge, activation of waste from the plant's water treatment plant, preparation of complex compounds with different percentages of the main active substances, determination of the synergistic effect between the components of the composition. The most important results are the determination of the balance between an effective combination of components in a composition that provides a high sulfur content; the definition of a list of metal oxides that can increase the absorption capacity of sulfur compounds; the development of an adsorbent with a high sulfur content and acceptable physical characteristics. The significance of the results obtained lies in the fact that the proposed desulfurization method is not only economically fea-sible, but also environmentally beneficial due to the reuse of station waste. The conducted research has made it possible to expand knowledge in the field of purification of gaseous fuels from sulfur com-pounds and identify effective adsorbent components that increase sulfur capacity.

The article discusses methods for calculating the moisture discharge voltage of insulators under various operating conditions (pollution, humidity, etc.) to identify patterns of environmental influence on operational characteristics, as well as to improve the reliability and safety of power grids. The main aim of the study is to compare two approaches to calculating the moisture discharge characteristics of insulators: the classical method based on the Tepler formula and an alternative approach that utilizes generalized parameters. These parameters can be easily obtained from the technical characteristics of insulators or design standards for automated calculations. To achieve this goal, the authors addressed several important tasks. First, a comprehensive analysis of the behavior of electrical discharges on the surface of insulators under various operating conditions, including standard and adverse environments, was conducted. Second, an automated tool was developed to quickly and accurately determine the values of moisture discharge voltage. Third, the proposed method was experimentally validated using the LK 70-110 insulator. The tests revealed a discharge voltage of 549 kV and an electric field intensity of 2.1 kV/cm, confirming the accuracy of the calculation method. The key findings of the study highlight the importance of considering factors such as the properties of insulator surfaces and the degree of contamination, especially in underground substations where humidity and pollution exhibit specific characteristics. The proposed approach proved effective both in standard and challenging operating conditions. The significance of the results lies in the creation of a tool that simplifies the calculation of moisture discharge characteristics of insulators.

The system was tested in MATLAB/Simulink to evaluate its performance. The most important results are the achievement of high voltage conversion efficiency of 97.42%, a minimized settling time of 0.1 seconds, and rapid convergence speed, which collectively demonstrate the system's ability to provide reliable and efficient operation for EV propulsion. The significance of obtained results is the potential to revolutionize EV motor drive systems by offering an innovative, highly efficient, and scalable solution. This system not only enhances energy utilization and motor performance but also supports the widespread adoption of sustainable EV technology.
