Hungarian experiences of the transition from traditional work to telework1

Laszlo Vasa P. Karácsony Yuriy Bilan Katalin Lipták

Publication Name: Transformations in Business and Economics

Publication Date: 2021-01-01

Volume: 20

Issue: 3

Page Range: 168-182

Description:

The global outbreak of the COVID-19 epidemic has radically transformed people’s daily lives since the spring of 2020. In addition to the direct health consequences of the virus, the epidemic has had a significant impact on the functioning of society, people’s lifestyles and has also had a fundamental impact on the world of work. The year 2020 marked a breakthrough in the spread of telework and “home office” work in Hungary, as this form of work was one of the necessary tools in the fight against the COVID-19 epidemic in order to reduce the number of personal contacts. Both employers and the masses of employees were able to experience the pros and cons of this. This period can be therefore considered as the main challenge of teleworking and working from home, which is undoubtedly caused by the COVID-19 epidemic. The research aims to answer the question of the impact of telework on the daily lives of Hungarian workers. In international comparison, the proportion of teleworkers in Hungary was low before the pandemic. As a result, a great many have experienced a drastic transition from traditional work to teleworking. The given questionnaire survey also confirmed that a significant proportion of employees had difficulties with teleworking at the beginning of the transition. These difficulties were mainly due to the fact that they were not technically prepared and that their daily routine, which they had become accustomed to in their traditional work, had been changed.

Lifestyle changes during Covid-19 period in Hungary–feedback of university students

Gyöngyvér Lacza Miklós Bánhidi

Publication Name: World Leisure Journal

Publication Date: 2020-10-01

Volume: 62

Issue: 4

Page Range: 325-330

Description:

Our study aimed to investigate the immediate impact of coronavirus on lifestyle changes among Hungarian students from leisure studies living in western part of Hungary. The study comprised an analysis of written reports by the trials focusing on the main lifestyle elements, such as biological needs, social duties and leisure. The respondents stated that the biggest change with them was to take hygienic requirements more seriously (47%), or paying more attention to have organized meals (25.5%). Despite our expectations, for 75.2% of the trials, it was important to study more, but also every third student (31.4%) had to do more physical work to earn money for their studies. Students wrote about suffering from the lack of entertainment businesses due to the lockdown. Instead of going out, they found it very important to do more sports (mainly workout 67.2%) and use virtual entertainment such as watching videos (47.4%) and reading books (44.5%).

A new approach to military logistical reconnaissance of railway infrastructure

Zsolt Lévai Gyula Szajkó

Publication Name: Journal of Defense Modeling and Simulation

Publication Date: 2025-01-01

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

A key factor in successful military operations is proper reconnaissance of the theater of operations, which includes mapping transport infrastructures to ensure the accurate location of materials, troops, and supplies. The aim of this research is to facilitate the success of logistical reconnaissance using unmanned aerial vehicles to be able to get more accurate information of the state of transport infrastructure. Rail transportation is well suited to carry out this experiment. As a result of an empirical research, an extended visual checklist is defined, which can be used as a basis for investigating the parameters of the elements of the railway infrastructure, including operation possibilities. The elements of the list have been examined by drones and their effectiveness has also been verified. The three-dimensional (3D) model could be created based on the drone-records, provides information on the condition of the tracks and their surroundings. The drawn conclusions will be used to define general requirements for the use of unmanned aerial vehicles for logistical reconnaissance. The application of the presented methodology can significantly improve the effectiveness of military logistical reconnaissance.

Leadership Readiness in Higher Education: A SILDM-Based Competency Diagnosis

Lívia Ablonczy-Mihályka Petra Kecskés Ildikó Némethová Eva Stradiotová

Publication Name: European Journal of Interdisciplinary Studies

Publication Date: 2025-01-01

Volume: 17

Issue: 2

Page Range: 44-60

Description:

This paper examines the self-perceived leadership readiness of first-year bachelor’s students enrolled in economics and business programmes, utilising the Korn Ferry Leadership Architect™ as a diagnostic tool within the broader conceptual framework of the Synced Integrated Leadership Development Model (SILDM). SILDM is a theoretically informed synthesis of established leadership and intercultural frameworks, designed to reflect the multifaceted nature of contemporary leadership. It integrates behavioural, ethical, relational, and cultural dimensions into a unified developmental perspective, addressing a key limitation in leadership education: the tendency to apply models in isolation without accounting for their interdependent dynamics. To operationalise this framework, a survey instrument based on 29 selected Korn Ferry competencies was administered to a sample of 1,307 first-year students, enabling structured self-assessment across four leadership domains: Thought, Results, People, and Self. The findings revealed higher levels of confidence in cognitive and task-oriented domains (Thought and Results), and notable developmental gaps in ethical self-regulation and interpersonal influence (Self and People). The paper proposes six pedagogically grounded interventions designed to foster more integrated, ethically grounded, and culturally responsive leadership development during the early stages of students’ academic and professional formation.

Investigation of the impact of a solar panel system installed on an heavy-duty truck trailer on fuel consumption at the ZalaZONE test track

András Háry Gergő Sütheö Letícia Pekk Richárd Peszleg

Publication Name: Advances in Science and Technology Research Journal

Publication Date: 2025-01-01

Volume: 19

Issue: 4

Page Range: 304-310

Description:

This study evaluates the impact of a solar panel system installed on a heavy-duty truck (HDV) trailer on fuel consumption, tested at the ZalaZONE track. Two vehicles were assessed – diesel-powered and an liquefied natural gas (LNG) powered truck, with the latter equipped with solar panels. Over five days, the solar system powered cabin electronics, reducing idle time and fuel use. While fuel and carbon dioxide (CO₂) savings were observed, performance was limited by battery charge and sunlight exposure. The results show potential for up to 10% fuel savings, demonstrating the system’s feasibility for reducing emissions in long-haul transport, though further optimization is needed.

Environmental effects, population genetic parameters, breeding value, phenotypic and genetic trend for age at first calving of limousin cows

Szabolcs Bene Eszter Szabó Márton Szűcs Judit Márton Ferenc Szabó Péter J. Polgár

Publication Name: Journal of Central European Agriculture

Publication Date: 2021-01-01

Volume: 22

Issue: 2

Page Range: 240-249

Description:

Some environmental effects, population genetic parameters, breeding value of Limousin breeding bulls, also phenotypic and genetic trends in the age at first calving (AFC) of cows between 1992 and 2013 were estimated. Data were served by the Limousin and Blonde d’Aquitaine Breeders Association, in Hungary. The study was extended to three herds and 1157 cows. GLM method was used for the study of different effects, the BLUP animal model for estimation of population genetic parameters and breeding values (BV), and one-way linear regression analysis for trend calculations. The overall mean value of the AFC was estimated to be 34.7±0.4 months. The contribution of the evaluated factors to the phenotype was as follows: herd 73.51%, birth year of cow 13.02%, sire 6.74%, birth season of cow 1.62%. The heritability of AFC proved to be low (h2 = 0.08±0.07 and h2 = 0.01±0.04). There were relatively small differences in the estimated BV of the studied sires for the AFC. Based on the phenotypic trend calculation, the AFC of cows decreased by an average of 0.33 months per year, however no significant change was found in the genetic trend during the study period.

Method of Assessing Cognitive Workload for Budapest Tram Drivers to Enhance Urban Traffic Safety †

Viktor Nagy Márton Nagy Attila Ferenc Bagosi

Publication Name: Engineering Proceedings

Publication Date: 2025-01-01

Volume: 113

Issue: 1

Page Range: Unknown

Description:

This study aims to enhance safety within the Budapest tram network by developing methods to assess and manage tram drivers’ cognitive workload. While defensive driving reduces accident risk, it becomes less effective when drivers are mentally overloaded. There is currently no reliable method to objectively measure this workload, which this research aims to develop. Trams frequently interact with unpredictable road users, increasing the likelihood of sudden braking and related injuries. Using accident data, high-risk locations were identified, and cognitive workload was assessed via eye-tracking (blinks and fixations) in a tram simulator. Participants drove two predefined routes and responded to unexpected events as they would in real traffic. Results reveal a correlation between blink/fixation frequency and cognitive load, enabling the identification of mentally demanding locations. These insights support targeted interventions to reduce driver workload and enhance operational safety.

The regional and geographical aspects of food security: A spatial analysis in the case of Azerbaijan, Hungary, Austria, Singapore and Georgia

Laszlo Vasa Lóránt Dávid Imre Varga Ragif Huseynov

Publication Name: Geographia Technica

Publication Date: 2020-10-01

Volume: 15

Issue: 2

Page Range: 161-170

Description:

Achieving food security is crucial, and a primary development goal world-wide. However, there is a difficulty in finding reliable data on the topic, which raised a problem for policymakers and researchers as well. Therefore, the present study aimed to fill in this gap by examining the dynamics of regional food security. The main research objective was to identify the determinants of food security in Azerbaijan, Singapore, Austria, Georgia and Hungary. Furthermore, a specific objective was to investigate the short- and long-term impacts of both endogenous and exogenous shocks on the food security of the selected countries. The study collected large scale panel dataset between 1992 and 2019. The empirical model suggested that food import, foreign direct investment, inflation, annual per capita income and Human Development Index had a positive, while the flow of food export had an adverse impact on the food security status of the selected countries. The study recommended to the governments of selected countries and to developmental organisations to achieve national food security through indigenous agricultural interventions along with supporting domestic growers by investing in agricultural education, skill development and infrastructure programs.

Colour afterimages: Computing and measuring virtual colour perception provided by two display types

Lorinc Garai András Horváth

Publication Name: 11th IEEE International Conference on Cognitive Infocommunications Coginfocom 2020 Proceedings

Publication Date: 2020-09-23

Volume: Unknown

Issue: Unknown

Page Range: 109-114

Description:

Afterimages are common and frequent perceptual phenomena of everyday life. When looking into a bright light source compared to environment and suddenly turning the eyes away from it, the illusionary image of the light source remains in perception, for a while. A subordinate to afterimages defined in our research is virtual colour perception that, according to our interpretation is an unusual and intense temporary colour perception provoked by quick colour change in the incident light. Modelling virtual colour perception can be useful in the field of visual design, for example in dynamic advertising. A computational kinetic model established for simulating and quantifying virtual colour perception was developed in our previous work and was validated with preliminary tests involving 20 observers. Validation test results were contestable due to the high variance (about 50 RSD%) of duration and intensity of afterimage results at each incident light colour change. Thus, in our current work, validation on one-observer tests was performed to minimize the variance of results. Further, these validation tests were run on two liquid crystal display (LCD) types: a nowadays frequently present In-Plane Switching (IPS) display providing vivid colours, and an older LCD-TN (twisted nematic) display.
