Page Range: 75-86

Description:

Population migration is one of the natural phenomena that occurs in society regardless of the form of social and economic system, and is considered within the framework and at the intersection of various sciences. However, military migration has its unique features and a distinct landscape of its processes, occurrences, and ongoing developments. The subject of this research is the complex of problems related to military migration in Ukraine, as well as its impact on the socio-economic development of territorial communities. The article aims to map both visible situations and latent processes in the territorial communities of Ukraine caused by military migration during the Russo-Ukrainian War. It is demonstrated that the consequences of military migration have both positive and negative aspects, thereby becoming a source of conflict and contributing to a decline in living standards within territorial communities. The need to combine the efforts of government bodies, civil society, and stakeholders in a comprehensive study of the consequences of military migration on communities is emphasized to develop effective models and strategies to overcome negative patterns. The fundamental issues surrounding military migration are reexamined to incorporate some of the significant new field data that has surfaced recently and to outline the policy implications of the results.

Daniel Rohacs Anita Boros Agnes Wanjiku Wangai

Publication Name: Sustainability Switzerland

Publication Date: 2020-05-01

Volume: 12

Issue: 9

Page Range: Unknown

Description:

Generally, the development process of the railway transport system is determined by the market pull effects initiated by the economy and society and the market push effects induced by technological progress. The policymakers can provide a balance between these two effects; this results in more effective, safer, and greener future railway systems. In developing countries, the railway systems lag compared to the developed economies. Therefore, the supporting management tools and legal supports for policymakers and strategic management play significant roles in the development of future sustainable transport systems. This paper deals with such required tools and the potential legal framework that support the development of sustainable railway systems in developing countries. The major novelty and advantages of the introduced methodology is the harmonised interaction between society, economic demands, technological development, and regulation. The proposed tools are applied to the Kenya rail system development.

Ferenc Bakó Marcell Kupi

Publication Name: Decision Making Applications in Management and Engineering

Publication Date: 2024-04-01

Volume: 7

Issue: 1

Page Range: 270-289

Description:

Today, tourism and digitalisation are very much intertwined. The phenomenon of tourism in the digital space - digital tourism - emerged with the birth of the internet and has grown in intensity over the years. The evolution of digitalisation has brought about a paradigm shift that has not only led consumers to adopt information and communication technologies, but has also greatly transformed consumer behaviour, preferences and motivations. Indeed, the development of technology has disrupted the traditional booking trends of tourists, their attitudes towards tourism and the social groups of tourists by providing dynamic online communication channels. Digital tourism users - digital tourists - are increasingly aware of the information and communication technologies, services and tools available to them, and are able to shape the market offer tailored to their needs through their actions and the data they provide. One of the most effective means of doing this is to share feedback and opinions online. In our research, I provide secondary information to support the importance of feedback and opinions, clarify its role in digital tourism, and then investigate the phenomenon of electronic-world-of-mouth through a questionnaire survey and decision tree analysis, and highlight the insights and implications of eWOM for digital tourists' behaviour in the online space based on opinions.

Gábor Csaba Soóki-Tóth Majid Movahedi Rad Muayad Habashneh Somfai Attila Majid Movahedi Rad

Publication Name: Compdyn Proceedings

Publication Date: 2025-01-01

Volume: Unknown

Issue: Unknown

Page Range: 3401-3412

Description:

This study introduces an elasto-plastic topology optimization approach tailored for structural systems subjected to cyclic loading. By incorporating material nonlinearity, the method provides a robust framework for designing structures that withstand repetitive loading efficiently, avoiding excessive material use. This optimization approach integrates the effects of cyclic loading to enhance structural resilience while minimizing mean compliance. The proposed method is particularly applicable for optimizing structural components in steel frameworks where material efficiency and load-bearing capacity are critical. By emphasizing the elasto-plastic behavior of materials, this study aims to offer a practical tool for engineers seeking resilient structural designs that balance strength and sustainability. Potential applications extend to structural elements in earthquake-resistant buildings, where managing material use is essential for both environmental and economic impact.

Description:

To preserve resources for future generations and promote rural development, supporting ecotourism is essential. This paper provides guidelines for developing ecotourism, highlighting its role in environmental conservation. While mass tourism benefits rural communities, it can cause significant environmental harm. Therefore, this research promotes ecotourism as a sustainable alternative. In rural areas, ecotourism supports development by responsibly using natural resources. The study focuses on the potential of rural settlements in the Semberija region of Bosnia and Herzegovina, assessing their capacity for ecotourism to aid local development. A decision model was developed, considering four main criteria - natural, infrastructure, socio-cultural, and economic - and their sub-criteria. This model evaluates six rural communities’ ecotourism potential. To determine the importance of each criterion, a fuzzy weighting method with the Bonferroni mean operator was used, revealing economic factors as the most influential. The fuzzy ranking method then ranked the settlements, with Amajlije identified as having the highest ecotourism potential. The findings suggest that promoting ecotourism in Amajlije and similar communities can support sustainable rural development, balancing environmental preservation with economic growth.

Investigating the Effect of Gear Ratio in the Case of Joint Multi-Objective Optimization of Electric Motor and Gearbox

György Istenes József Polák

Publication Name: Energies

Publication Date: 2024-03-01

Volume: 17

Issue: 5

Page Range: Unknown

Description:

In this paper, a software framework is presented through an application that is able to jointly optimize an electric motor and a gearbox for the design of a drive system for electric vehicles. The framework employs a global optimization method and uses both analytical and finite element method (FEM) models to evaluate the objective functions. The optimization process is supported by a statistical surrogate model, which allows a large reduction of runtime. An earlier version of this framework was only suitable for electric motor optimization. In the application presented in a previous paper, the motor of a belt-driven electric drive system was optimized. In this paper, the optimization of the same drive system is shown, but now with a combined optimization of a gear drive and motor. The objective functions of optimization are minimizing the total loss energy and the weight of the drive system. The optimization results are compared with previous results to demonstrate the further potential of joint optimization.

Publication Name: Geojournal of Tourism and Geosites

Publication Date: 2025-01-01

Volume: 60

Issue: Unknown

Page Range: 1348-1361

Description:

Despite Kazakhstan’s unique natural and climatic features, rich recreational potential, and developed sanatorium infrastructure, the country has not yet become a competitive international tourist destination. In particular, the Akmola region, which has notable natural assets, remains underdeveloped in terms of tourism, and its potential is not effectively utilized to attract foreign tourists. This study aims to analyze the current state of tourism in the Akmola region, identify key problems, and propose possible solutions to enhance its development. To assess public perception, a 14-item questionnaire was created based on relevant literature and distributed via social networks. Survey questions were offered in the form of docs.google.com to facilitate distribution. A total of 503 respondents participated in the survey. Results show that Burabai National Park was recognized by 43.1% of respondents as having high tourism potential, followed by Kokshetau National Park (28.2%) and Buiratau (16.5%). At the same time, as for the attractiveness of tourist and recreational facilities in Akmola region, 57.1% of respondents answered that they are unique in nature, and 26.2% believe that ecotourism has great opportunities. Because the unique nature of Akmola region is a diverse landscape that includes: mountains, lakes, rivers, forests and steppes. However, 71% of respondents expressed dissatisfaction with the level of hotel development in the region, and over 50% emphasized the need to improve tourism infrastructure. The findings highlight the necessity of integrated development of the region’s tourist and recreational resources. In particular, it is necessary to repair the main roads, ensure the renewal of public transport and tourist routes. This allows us to provide accommodation in accordance with international standards, provide quality services at an affordable price and attract significant investment. Strengthening these aspects will not only improve the attractiveness of the region to global tourists but also contribute to the socio-economic well-being of the local population and foster the sustainable development of the Akmola region. Ultimately, the proposed strategies for the development of the tourism industry in Akmola region should be aimed at the effective use of local resources and increasing the competitiveness of the region, improving the socio-cultural level of the region by increasing the flow of tourists.

Description:

Random vibration analysis is a mathematical tool that offers great advantages in predicting the mechanical response of structural systems subjected to external dynamic loads whose nature is intrinsically stochastic, as in cases of sea waves, wind pressure, and vibrations due to road asperity. Using random vibration analysis is possible, when the input is properly modeled as a stochastic process, to derive pieces of information about the structural response with a high quality (if compared with other tools), especially in terms of reliability prevision. Moreover, the random vibration approach is quite complex in cases of non-linearity cases, as well as for non-stationary inputs, as in cases of seismic events. For non-stationary inputs, the assessment of second-order spectral moments requires resolving the Lyapunov matrix differential equation. In this research, a numerical procedure is proposed, providing an expression of response in the state-space that, to our best knowledge, has not yet been presented in the literature, by using a formal justification in accordance with earthquake input modeled as a modulated white noise with evolutive parameters. The computational efforts are reduced by considering the symmetry feature of the covariance matrix. The adopted approach is applied to analyze a multi-story building, aiming to determine the reliability related to the maximum inter-story displacement surpassing a specified acceptable threshold. The building is presumed to experience seismic input characterized by a non-stationary process in both amplitude and frequency, utilizing a general Kanai–Tajimi earthquake input stationary model. The adopted case study is modeled in the form of a multi-degree-of-freedom plane shear frame system.

Volume: Unknown

Issue: Unknown

Page Range: 269-300

Description:

In the framework of ecologically sustainable development, this research paper explores the crucial relationship between financial literacy and the use of green energy. The study looks into how institutional and individual financial knowledge affects choices about energy-efficient technology, sustainable financial products, and investments in renewable energy. This paper highlights important gaps in green energy financial literacy that impede the shift to sustainable energy systems by thoroughly analyzing the body of existing literature, actual data, and theoretical frameworks. The study uses a mixed-methods approach, combining qualitative interviews with policymakers and industry professionals with quantitative surveys of 2,500 respondents from a range of demographic categories. Important findings show that although 78% of respondents are generally aware of the advantages of green energy, only 32% of them are sufficiently knowledgeable about green investments, tax breaks, financing options, and long-term cost-benefit evaluations.
