Wounded Collective Identity in Europe: Trauma, Religiosity, Modernization and Visions of the Future Based on Empirical Studies of Thirty-Eight European Countries
Publication Name: Religion and Society in Central and Eastern Europe
Publication Date: 2025-12-30
Volume: 18
Issue: 1
Page Range: 3-23
Description:
Máté-Tóth (2015, 2022) uses the concept of woundedness and the theory of wounded collective identity to describe the collective self-understanding of the Central and Eastern European region. An international study by the Századvég Foundation in 2022, based on 38,000 respondents (1,000 per country), provided an opportunity to test the theory on a European sample. This study sought to answer the question of the prevalence of a wounded collective identity in Hungary and other European countries, and whether the theory has any region-specific relevance. The results show that regional in-betweenness can be considered to be a determining factor for wounded collective identity.

CLUSTERING ANALYSIS OF PATCHOULI PLANTATIONS FOR SUSTAINABLE PATCHOULI OIL SUPPLY CHAIN USING K-MEANS ALGORITHM
Publication Name: Journal of Applied Engineering and Technological Science
Publication Date: 2025-12-29
Volume: 7
Issue: 1
Page Range: 337-355
Description:
Growing demand for patchouli oil has undoubtedly become an opportunity for the patchouli industry, particularly in Aceh, which supplies about 80% of Indonesia’s patchouli oil in the global supply chain system. However, the opportunity is often misguided by farmers and even the government, which implements various programs related to patchouli cultivation without identifying the potential land that is suitable to be used for it. The condition indicated that not every land is suitable for patchouli cultivation. Thus, it is necessary to cluster the distribution of existing patchouli plantations. The clustering aims to identify the existing patchouli plantations that have the potential for replication. This study uses the K-Means method that combines variables (the planting land, the harvesting land, and total production) to provide information on the plantation’s potential scale in each region. The clustering measurement pointed out that the plantation in South Aceh Regency has the most potential land for sustainable cultivation, followed by several other areas included in Cluster 2 and Cluster 3. The study’s result is essential in contributing significantly to optimizing patchouli cultivation management sustainability to fulfill Aceh Province’s role as the best quality patchouli oil supplier.

A Spherical Fuzzy ELECTRE III-Based Framework for Evaluating Flood Risk Management Strategies in Vulnerable Watersheds
Publication Name: Boletim Da Sociedade Paranaense De Matematica
Publication Date: 2025-12-29
Volume: 44
Issue: Unknown
Page Range: 1-14
Description:
Flooding is one of the most widespread and damaging natural hazards worldwide, causing significant economic losses, environmental degradation, and risks to human life, particularly in vulnerable watersheds. The multi-criteria decision-making dilemma of managing flood risks in prone watersheds is associated with conflicting economic, social, and environmental objectives. To assess and rank the flood risk management options, this research suggests a single model that should be developed using a mix of the fuzzy analytic hierarchy process and ELECTRE III approaches. The fuzzy analytic hierarchy process is used to capture the uncertainty and subjectivity of the pairwise comparison of decision-makers. Alternative management strategies are ranked using the ELECTRE III technique. The suggested approach is applied to an empirically vulnerable watershed, demonstrating its viability. The suggested fuzzy framework aids decision-makers in selecting the best course of action even before a flood occurs. Watershed managers can use the findings as a scientifically validated tool for resource allocation in flood risk reduction, as they provide a clear and sound hierarchy of strategies that include both structural and non-structural measures.

Comparative Analysis of Electric Vehicle Energy Consumption in Urban and Highway Environments Using CAN-Based Data Collection
Publication Name: Engineering Perspective
Publication Date: 2025-12-28
Volume: 5
Issue: 1 Special Issue
Page Range: 8-13
Description:
This study presents a comparative analysis of the energy consumption characteristics of Volkswagen Golf equipped with an electric powertrain in urban and interurban (highway) driving environments. The primary objective of the research is to determine which traffic context offers more favorable operating conditions in terms of energy efficiency for this vehicle category. Special emphasis is placed on the role of regenerative braking, particularly in urban traffic characterized by frequent acceleration and deceleration cycles, which may significantly influence the vehicle’s specific energy consumption through energy recovery mechanisms. The measurement data were recorded under real-world traffic conditions along two representative routes: a highway section between Zalaegerszeg and Keszthely, and the urban road network within Zalaegerszeg. During data collection, vehicle parameters extracted from the CAN network—including brake pressure, speed, accelerator pedal position, drivetrain power, battery voltage and current, state of charge, as well as longitudinal and lateral acceleration—were recorded using a custom program developed in Simulink and a Kvaser CAN logger device. The goal of the analysis is to compare the energy efficiency indicators of the two driving profiles and to draw conclusions, based on the recorded data, about the real-world efficiency of electric vehicle operation in urban settings. The findings may contribute to the optimization of operational strategies for electric vehicles and serve as a foundation for future large-scale investigations.

Sustainable Battery Recycling in the Age of Electromobility
Publication Name: Engineering Perspective
Publication Date: 2025-12-28
Volume: 5
Issue: Special Issue
Page Range: 18-27
Description:
The rapid spread of electric vehicles offers numerous opportunities to reduce greenhouse gas emissions, but also creates new and complex challenges for the automotive industry, particularly in terms of battery life cycle management. Electric cars are currently powered mostly by lithium-ion batteries, which rely on critical raw materials such as lithium, cobalt, nickel, and manganese. These resources are limited, and their extraction often involves energy-intensive and polluting mining processes that can have a serious impact on soil, water resources, and local communities. As demand for electric vehicles grows worldwide, so does the pressure on the sustainability of raw material supplies. The efficient recycling of batteries plays a key role in solving these problems. Recycling not only reduces the demand for primary raw materials, but also reduces waste and contributes to lowering the environmental footprint of electromobility. The study provides a comprehensive overview of the methods currently used to recycle electric vehicle batteries. The most common technologies include pyrometallurgical processes, which recover metals through high-temperature smelting, hydrometallurgical methods, which use chemical solutions to extract valuable materials, and direct recycling, which aims to reuse individual battery components directly. Each solution has its own advantages and limitations in terms of efficiency, cost, environmental safety, and industrial scalability. The study also pays special attention to new, innovative approaches. Automated dismantling technologies, for example, can make dismantling processes safer and faster, while reducing risks to human health. Finally, the regulatory environment and industry practices also play a key role in ensuring the long-term sustainability of battery recycling and the supply chain. The aim of the study is to contribute to the development of a circular automotive industry and to support the spread of sustainable battery management from both a technological and industrial perspective.

Testing the Real Capacity of the Battery
Publication Name: Engineering Perspective
Publication Date: 2025-12-28
Volume: 5
Issue: 1 Special Issue
Page Range: 1-7
Description:
As electric motoring becomes more and more widespread, it is important to develop appropriate diagnostic measurements, especially for the increased electrical system. The most important part of the electrical system is the high voltage lithium-ion battery. Monitoring battery condition is essential to avoid failures and extend battery life, as these batteries degrade over time depending on the number of cycles, operating temperature, and charging habits. The project presented the contactless diagnostics of a Volkswagen e-Golf lithium-ion battery and analyze its capacity degradation through data acquisition via the Controller Area Network (CAN). The developed method allows to analyze the battery status and performance without disruption, which contributes to a more sustainable and economical vehicle usage. The measurement procedures include the analysis of the values of the state of health (SOH) and state of charge (SOC) indicators. The results will also provide insights into the optimization of the use of diagnostic tools and future battery maintenance options. To validate the method, two measurement scenarios were conducted: one on a chassis dynamometer and another under real-world driving conditions. The findings confirmed that contactless data acquisition can effectively detect cell imbalances and early degradation signs. The approach outlined in this study supports the implementation of efficient, scalable diagnostic solutions in both research and industrial settings.

Analysis of Following Distance Measurement and Compliance in Road Traffic
Publication Name: Engineering Perspective
Publication Date: 2025-12-28
Volume: 5
Issue: Special Issue
Page Range: 14-17
Description:
The study examines the observance of safe following distances under real traffic conditions. Maintaining an appropriate following distance plays a key role in accident prevention, as it gives drivers sufficient time to perceive hazards and react appropriately. To record empirical data, a rear radar sensor was installed on the test vehicle, which continuously measured the distance and speed of the vehicle behind. This method allowed for a detailed analysis of how the following distance changes as a function of speed. The collected data was compared with the minimum safety requirements based on reaction time and braking performance described in the literature. The comparison shows the extent to which actual driver behavior deviates from the recommended safety standards. Although modern vehicles are increasingly equipped with driver assistance systems, such as automatic emergency braking, the vast majority of vehicles in Hungary are not yet equipped with such systems. As a result, road safety depends largely on individual driver decisions and compliance with the rules. The results highlight the potential accident risks arising from inadequate following distances, especially in everyday traffic situations where drivers often underestimate the distance required for a safe stop. The measurement result show that most drivers following distance is shorter than the average stopping distance. The research contributes to a deeper understanding of domestic driving habits and provides a basis for the development of road safety campaigns, driver training programs, and possible regulatory measures. Overall, the results emphasize the importance of maintaining a safe following distance as a simple, cost-effective, and efficient means of improving road safety.

Cultural Fault Lines and Development Trajectories in East-Central Europe
Publication Name: Engineering Perspective
Publication Date: 2025-12-28
Volume: 5
Issue: Special Issue
Page Range: 37-44
Description:
This paper explores the divergent developmental trajectories of East-Central European countries by examining the cultural fault lines between Western (European) and Orthodox (Slavic/Russian) civilizations. The study assesses how these civilizational backgrounds have influenced economic performance, governance structures, social trust, labor market dynamics, and institutional development since the fall of communism. The analysis uses a comparative cross-country design based on secondary data from international sources. Countries are classified according to the cultural models of Huntington, De Blij & Muller, and Fellmann et al. A set of macroeconomic and societal indicators—including GDP per capita, Global Innovation Index rankings, labor force characteristics, and trust levels—is examined to identify patterns of divergence and convergence across cultural blocs. The results show that Western-aligned countries generally perform better economically and exhibit higher levels of social trust and institutional stability. At the same time, the relationship between culture and development is not deterministic. Several Orthodox countries demonstrate notable progress, indicating that integration dynamics, policy choices, and governance quality also play significant roles. The research offers an interdisciplinary perspective that connects cultural theory with observable economic and political outcomes. It contributes to a deeper understanding of how historical-cultural legacies shape developmental potential in East-Central Europe and provides insights for regional policy design, institutional reform, and future growth strategies.

Main aspects of epigenetics of gestational and female genital tumors
Publication Name: Orvosi Hetilap
Publication Date: 2025-12-28
Volume: 166
Issue: 52
Page Range: 2043-2054
Description:
The genotype of our cells is almost the same for all cells in our body, but due to epigenetic effects, their phenotype can show significant differences. Epigenetics is a relatively new field of molecular biology that deals with the changes affecting the heritable phenotype, gene expression and gene activity in addition to the given genotype. The gene expression of immune and tumor cells is regulated by epigenetic processes. These processes can enhance the immune system evasion mechanisms of various tumor cells, while the results of other processes can actually help the immune system function. Our paper explores the epigenetic aspects of gynecological tumors through a thorough review of the Hungarian and international literature, with particular attention to the tumor processes of the cervix, uterus, ovary and breast. It also affects gestational tumors. It discusses the epigenetics of endometriosis, which does not belong to the group of classic tumor diseases, but in terms of its pathomechanism shows many similarities with other tumors. Finally, the paper discusses new findings in epigenetic medicine and therapy. Orv Hetil. 2025; 166(52): 2043–2054.
