EXAMINING THE DEMAND RELATIONSHIPS OF BETWEEN RELIGIOUS TOURISM AND EXAMPLE OF URBAN ATTRACTIONS IN THE GYŐR-PANNONHALMA TOURIST AREA

Anne Marie Lebrun Kevser Çinar Csaba Kőmíves Ferenc Darabos

Publication Name: Geojournal of Tourism and Geosites

Publication Date: 2024-01-01

Volume: 57

Issue: Unknown

Page Range: 2114-2122

Description:

This study examines the sacred places of Győr-Moson-Sopron County (Western Hungary), focusing on people's attitudes towards them. Pannonhalma is part of the world heritage, the Győr Cathedral, and the five church festivals (Roman Catholic, Jewish, Reformed, Lutheran, Greek Oriental) held in the city are important places of worship. The aim of the study was to analyse the scope of religious tourism in the World Heritage Site and to examine the demographics of the demand for urban religious centres. Primary research was conducted with a quantitative (questionnaire) survey between 10th September 2023 and 30th October 2023. The sample of 666 persons is not representative, respondents were chosen with arbitrary sampling. Data were processed using the SPSS 23 statistical program package which contains cross-table analysis, in addition to the descriptive statistical analyses. The most important finding of the study is that travel propensity is determined by the importance and familiarity of urban landmarks, and significance can be found here. Respondents' age, educational attainment and gender also show significant differences in terms of the attractiveness of visiting attractions (distance from their residence). The research investigated the demand for Roman Catholic, Jewish, Reformed, Evangelical and Greek Orthodox religious attractions in Győr and the Pannonhalma Benedictine Abbey, a World Heritage Site, according to local specificity. There is significant evidence of a regional pull effect of the World Heritage status of the built heritage site. The city churches and their associated events are most popular with the elderly, women and those with higher education.

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2024-01-01

Volume: 21

Issue: 6

Page Range: 303-322

Description:

This paper presents an up-and-running control system, using IoT hardware, for multiple decentralized mechanical ventilation with heat recovery (dMVHR) units to enhance the overall performance of heat exchangers and the air quality of a real-life environment. The implemented control and monitoring system is able to measure the thermal efficiency of the complete ventilation system under real working conditions. Fan speed is automated based on the measured CO2eq levels in the bedrooms of the building, however, manual control is also possible. Temperature, relative humidity and CO2eq levels can be monitored live on the user’s smart device, while data can be exported through Google cloud system. Data values can be stored and accessed any time by legit users. The thermal efficiency of the individual units and the whole ventilation system was investigated and experimentally verified under real-life conditions, using the implemented centralized control and monitoring system.

A Novel Gradient-Weighted Voting Approach for Classical and Fuzzy Circular Hough Transforms and Their Application in Medical Image Analysis—Case Study: Colonoscopy

Raneem Ismail Szilvia Nagy

Publication Name: Applied Sciences Switzerland

Publication Date: 2023-08-01

Volume: 13

Issue: 16

Page Range: Unknown

Description:

Featured Application: The circular fuzzy Hough transform with gradient-weighted voting can be used for finding the contours of circle-like shapes, such as colorectal polyps on colonoscopy images, as well as other cases that require a given relative gradient edge around the circle-like objects. Classical circular Hough transform was proven to be effective for some types of colorectal polyps. However, the polyps are very rarely perfectly circular, so some tolerance is needed, that can be ensured by applying fuzzy Hough transform instead of the classical one. In addition, the edge detection method, which is used as a preprocessing step of the Hough transforms, was changed from the generally used Canny method to Prewitt that detects fewer edge points outside of the polyp contours and also a smaller number of points to be transformed based on statistical data from three colonoscopy databases. According to the statistical study we performed, in the colonoscopy images the polyp contours usually belong to gradient domain of neither too large, nor too small gradients, though they can also have stronger or weaker segments. In order to prioritize the gradient domain typical for the polyps, a relative gradient-based thresholding as well as a gradient-weighted voting was introduced in this paper. For evaluating the improvement of the shape deviation tolerance of the classical and fuzzy Hough transforms, the maximum radial displacement and the average radius were used to characterize the roundness of the objects to be detected. The gradient thresholding proved to decrease the calculation time to less than 50% of the full Hough transforms, and the number of the resulting circles outside the polyp’s environment also decreased, especially for low resolution images.

Shifting Employment: Labor Challenges in Czechia, Hungary and Slovakia Beyond the Pandemic

József Poór Szonja Jenei Szilvia Módosné Szalai Zdeněk Caha Allen Engle

Publication Name: Administrative Sciences

Publication Date: 2026-05-01

Volume: 16

Issue: 5

Page Range: Unknown

Description:

The employment and labor market landscape has undergone significant transformations globally, including the three Central European countries examined in this study. Over the past decades, organizations in this region have transitioned from a state of full employment to labor shortages, raising the question: What factors have driven these changes? Our study aims to present a theoretical framework highlighting key macro-level factors, such as demographic trends, economic development, labor market dynamics, the impact of the COVID-19 pandemic, and the role of robotization and artificial intelligence. Based on two empirical studies conducted in 2019 and 2022 among Czech, Hungarian, and Slovak organizations, we analyzed the extent and causes of labor shortages, as well as the labor market effects of robotization. Using descriptive and non-parametric statistical methods, including frequency analysis and Mann–Whitney U tests, the study examined key trends and compared the two periods to identify significant shifts. The analytical approach of this study primarily aims to compare perceptions across occupational groups and between the two survey waves (2019 and 2022). Because most variables were measured on ordinal Likert-type scales and the datasets represent independent cross-sectional samples rather than a panel dataset, non-parametric methods were considered the most appropriate. More advanced causal modeling techniques, such as regression or factor analysis, were not applied because the objective of the research was exploratory and comparative rather than to establish causal relationships between variables. The findings reveal significant shifts in the perceived causes of labor shortages across occupational groups in the surveyed Central European organizations. In particular, increasing labor shortages were observed in specific job categories, alongside changes in the relative importance of the underlying drivers of labor shortages. While adopting robotization and artificial intelligence has been positively received, demographic decline and emigration remain critical challenges. The study provides practical insights for policymakers and corporate leaders regarding labor market challenges, workforce planning, and the potential role of robotization and artificial intelligence in addressing labor shortages. Although the research is based on a non-representative sample, it offers valuable insights into the Central European region’s employment and labor market trends. Future research could examine whether, in hard-to-fill positions, robotization and AI primarily provide indirect support by augmenting and reallocating human work, or whether they may serve as direct substitutes.

Linking Internal CSR and External CSR to Sustainable Competitive Advantage via Green Ambidextrous Innovation: A Newer Perspective on Greenwashing Corporate Strategies

Laura Broccardo Sonali Singh Pragya Gupta Yicheng Zhang Attila Kurucz

Publication Name: Corporate Social Responsibility and Environmental Management

Publication Date: 2026-05-01

Volume: 33

Issue: 3

Page Range: 3125-3144

Description:

Integrating corporate social responsibility (CSR) with a firm's strategies may not only improve the trust of various stakeholders but also enhance innovative behavior. This further positions the firm for a competitive advantage, confirming good performance in a socially responsible business environment. Most past studies have focused on external stakeholders. However, this study examines the role of both internal and external stakeholders' perceptions of CSR as pivotal drivers of sustainable competitive advantage (SCA) in the contemporary business landscape. It further examines how organizations frequently engage in greenwashing, making misleading claims about their environmental and sustainability initiatives. The study further incorporates the mediating mechanism of green ambidextrous innovation (GAI) that affects the relationship between CSR perceptions (internal and external) and SCA. Grounded in the theoretical underpinnings of upper echelons theory (UET) and resource orchestration theory (ROT), the analysis was conducted using data from 330 respondents, employing the PLS-SEM technique. The findings reveal that perceived greenwashing has a negative impact on external CSR, but it does not affect internal CSR perceptions. The study also observed that GAI partially mediates the relationship between internal CSR, external CSR, and SCA. The study makes crucial theoretical and practical contributions that help firms to build strong relationships with stakeholders, drive innovation to accelerate sustainable efforts, and achieve a strategic competitive advantage that avoids perceived greenwashing.

Evaluation of steel hardenability by JM®-test

D. Iljkic N. Tomasic G. E. Totten B. Smoljan Imre Felde Tamás Réti

Publication Name: Materials Science Forum

Publication Date: 2007-01-01

Volume: 537-538

Issue: Unknown

Page Range: 607-614

Description:

The modified Jominy-test was designed for prediction of hardenability of high-hardenability tool steels and possibility of application of modified Jominy-test in computer simulation of quenching of high-hardenability tool steels has been investigated. Because of high hardenability there are limits in application of original Jominy-specimen in simulation of quenching of steels. The performance of investigated modified Jominy-test in simulation of quenching of high-hardenability tool steels was estimated by comparison of cooling curves of modified Jominy-specimen (JM®-specimen) and cylindrical specimen. The influence of dimension of JM®-specimen on cooling curves has been investigated. The time of cooling, t8/5 relevant for results of quenching was predicted. Modified Jominy-test can be applied in simulation of quenching of steel with higher hardenability rather than original Jominy-test.

At the Borderline of Public and Private Law: The Restitution of Cultural Property Held in Public Collections in Hungary

Vanda Vadász Viktória Verebélyi

Publication Name: Santander Art and Culture Law Review

Publication Date: 2024-01-01

Volume: 2024

Issue: 2

Page Range: 181-208

Description:

During the Second World War, and thereafter until the end of the communist regime in 1989, a massive amount of private-ly owned works of art came into the possession of the Hungarian state. The ownership of the property thus collected was only par-tially clarified after the war. After the fall of communism, national-ized cultural property was subject to restitution laws, but restitution typically meant partial compensation. The aim of this article is to highlight the shortcomings that still characterize the restitution of cultural property held in public collections in Hungary. After summa-rizing the historical-legal situation pertaining to restitution measures in Central and Eastern Europe, we provide a comprehensive overview of the Hungarian legal environment in terms of restitution. The focus is on the restitution rules adopted in the 2010s that were intended to settle the possession of cultural property held in public collections. The roots of constitutional issues related to the regulation arise from and are reflected in the intermingling of private law and public law characteristics and guarantees. In the presentation of civil law disputes concerning the ownership rights of property held in public collections, we outline the characteristics of the Hungarian regula-tory framework regarding protected cultural property and the issues arising from their application. Finally, we provide an overview of the European Court of Human Rights’ jurisprudence on the protection of property rights and an assessment of Hungarian regulations before the Court. We claim that the lack of predictability and certainty of the latter authority’s proceedings may lead to human rights issues.
