The Role of the Civil Sector in Contribution to Social Well-Being and in Shaping Active Citizenship

Adrienn Reisinger Márta Nárai

Publication Name: Springer Proceedings in Business and Economics

Publication Date: 2019-01-01

Volume: Unknown

Issue: Unknown

Page Range: 101-118

Description:

Nowadays social and economic issues can have unfavourable consequences; social problems both at the global and local level are outstanding and it is essential to find solutions because of the efficient functioning of the economy and the society. Also, state and for-profit actors can take part in solving these problems, but there are lots of services which can be provided only by civil organizations. The first part of the paper presents the concept of civil organizations and current issues of them in Hungary. After that, it describes the way of their contribution to the active citizenship and to social well-being based on theoretical and empirical background. We made a questionnaire research in 2013 among civil organizations at the regional level in Hungary; we would like to show the main results of it. This paper presents a review of the main participatory forms of the organizations through which they can contribute to the improvement of the services and to the expanding of the supply. An important message of the paper is that civil organizations cannot operate without active citizens, our study will also show the methods how civil organizations can contribute to the active citizenship and what kind of elements and barriers have this process. This paper can add to the literature of the civil organizations and can be useful both for policy makers, researchers and citizens.

Numerical determination of orthotropic material properties of textile composite layers and their validation by measurement

Béla M. Csizmadia Gergely Bojtár János Égert

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2017-01-01

Volume: 14

Issue: 2

Page Range: 47-67

Description:

The knowledge of orthotropic material properties of composite layers is very important for mechanical design of machine structures from composite material. This information cannot be found in related professional literature therefore it is necessary to determine by measurement, by basic experiments of mechanics of materials. The paper presents a new 3D finite element layer model-cell based on the meso-structure of a textile composite layer, with which one shall be able to determine the material constants of an orthotropic layer. The applicability of the numerical layer model-cell and the accuracy of the numerical results are confirmed by experimental results. The numerically determined material properties of the layers are used at mechanical modeling and computation of complex, layered composite structures.

Enhancing Seismic Performance: A Comprehensive Study on Masonry and Reinforced Concrete Structures Considering Soil Properties and Environmental Impact Assessment

O. Kegyes-Brassai Nurullah Bektaş Benjamin Labar

Publication Name: Advances in Civil Engineering

Publication Date: 2024-01-01

Volume: 2024

Issue: Unknown

Page Range: Unknown

Description:

Approximately 20,000 people are killed annually on average by building and infrastructure collapses and failures caused by seismic activities. In earlier times, seismic design codes and specifications set minimal requirements for life safety performance levels. Earthquakes can be thought of as recurring events in seismically active areas, with severity states ranging from serviceability to ultimate levels. Buildings designed in accordance with site-specific response spectra, which take into account soil properties based on ground motion amplification data, are better at withstanding such forces and serving their design purposes. This study aims to investigate the site response of reinforced and masonry buildings, considering the effect of soil properties based on the amplification of ground motion data, and to compare the life cycle assessment of the buildings under consideration based on the design and the site-specific response spectrum. In terms of soil properties and site-specific response spectra, STRATA is used to determine the site-specific response for the considered locations for a return period of 475 years for 100 realizations based on the randomization of site properties. For structural analysis, AxisVM software, which is a compatible finite element analysis, is used for building design and analysis, generating comparative results based on the design- and site-specific spectra. To determine and identify potential failures in the model, response spectra were applied to understand the difference in horizontal deflection in two different instances (for elastic design- and site-specific spectra). After building design and analysis is performed, a life cycle analysis in terms of environmental impact assesments using OpenLCA and IdematLightLCA is done. This is done to ascertain the additional expenses in terms of ecocosts and carbon footprints on some failed elements in the structure which are required to make the buildings more resilient when the site-specific response spectrum is applied and to compare the potential economic losses that may occur based on ecological costs. The study presents a comprehensive investigation into the seismic response of masonry and reinforced concrete buildings in Győr, Hungary, incorporating advanced geophysical techniques like multichannel surface wave (MASW) and structural analysis software, AxisVM. Additionally, tailored retrofitting strategies are explored to enhance structural resilience in seismic-prone regions. Significant ground amplifications in soil properties across different profiles are revealed, emphasizing the effectiveness of these strategies in reducing structural deflection and improving resilience. Highlights of the results are observed where the site-specific response spectra are higher than the EC8 design response spectrum. Furthermore, the research underscores the substantial environmental impact, considering both ecocosts and CO2 emissions associated with retrofitting measures, highlighting the importance of sustainable structural interventions in mitigating seismic risks.

Description:

The subject of this research is digital technologies, increasingly applied in the key processes of labour market organisation and the implementation and formalisation of employment relationships. The article provides an analysis of the use of information technologies in the labour sector, forming the basis for researching new forms of employment. The relevance of this study is driven by the need to adapt to the modern digital labour market, dictated by global innovative changes and the application of digital and information technologies, which require normative legal regulation of new forms of employment relationships. These evolving paradigms are poised to shape the future labour market, which is increasingly predicated on electronic formats and the rapid development of new employment constructs, encompassing self-employment, remote work, and freelancing modalities. The scholarly novelty of this study resides in the systematic categorisation and analysis of the principal trends reflecting shifts in the dynamics between employers and employees, influenced by pivotal information technologies in the modern labour market.

Traffic Sign Detection Related to Weather Variations

Csaba Koren Ziyad N. Aldoski

Publication Name: Lecture Notes in Networks and Systems

Publication Date: 2026-01-01

Volume: 1768 LNNS

Issue: Unknown

Page Range: 190-196

Description:

Environmental variability poses a significant challenge to the reliability of vision-based perception systems in autonomous vehicles (AVs), particularly in the context of traffic sign detection. This study evaluates the performance of the YOLOv8 deep learning model under clear, rainy, and snowy conditions. Real-world video data captured in clear weather was augmented using simulation techniques to replicate realistic rain and snow effects, including precipitation, motion blur, lens distortion, and reduced visibility. Detection performance was assessed using detection rate, sharpness, mean saturation, and intensity. Results show a marked decline in accuracy under adverse conditions, with snow causing further issues like occlusion, reduced contrast, and altered reflectivity. Additionally, detection resilience varied among sign classes; high-contrast signs with distinct geometric shapes were detected more reliably than those with fine details or low color contrast. These findings highlight the critical need for robust perception algorithms and the advancement of AV vision systems capable of maintaining accuracy across challenging environmental conditions.

Opportunities of VR for Teaching History

Attila Pongracz Balint Lampert Csaba Sándor Horváth

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2024-01-01

Volume: 21

Issue: 3

Page Range: 143-162

Description:

The present study examines the opportunities of VR in the context of humanities and arts and – within their frameworks – in that, of history. Its novelty clearly lies in the fact that in this fields’ cyberspace is not used either by public or by higher education. The inclusion of info-communication tools for history teaching, does not really follow the current trajectory of development. Educators usually work according to methods that have become the most common and familiar. This research clearly revealed that students, who regularly use the VR space, in a History course of teacher training, consider it experiential, user-friendly, simple, problem-oriented and thus, easier to visualize historical facts. The regular and widespread use of VR software could greatly and easily help to progress the historical curriculum space.
