Examining the Virtues of Organisational Citizenship Behaviour (OCB) at an SME
41-52Views:317Nowadays, especially in the Eastern region of Hungary, small businesses face an increasing challenge in attracting and retaining a well-qualified workforce that is able to accept and commit to the goals of SMEs. This is due to the promising career prospects offered by foreign-owned large companies locating here. However, if SME employees possess the virtues of organisational citizenship behaviour (OCB), they will develop a stronger commitment to the organisation. The aim of our research was to explore the extent to which the five OCB virtues; sportsmanship, conscientiousness, altruism, politeness and civic virtue are present in a small construction company in Hajdú-Bihar county. Our survey was carried out using a questionnaire method, which was analysed as a function of length of service, education and age. The main findings are that there is a strong correlation between the presence of OCB characteristics and age and length of time spent with the firm.

Analysis of labor consumption in Hungary in the last 5 years
127-137Views:252The main idea of my research was the statement of the President of the Hungarian Fruit and Vegetable Interprofessional Organization and Product Council (Ferenc Apáti), according to which the main obstacle to the future development of horticulture and the development plans of horticultural enterprises is capital shortfall factors). The employment of seasonal workers in the production of grapes and fruit and in horticultural farms is of the greatest importance. As a result, in my research, I examined the use of labor by those working in agriculture over the past 5 years. I reviewed how the coronavirus has affected the time spent by seasonal workers at work in the recent past. Since there are a lot of work phases in agriculture where there is a temporary use of labor, I considered it important to get around this topic better. As seasonal agricultural workers are often able to reach their agricultural jobs through travel and border crossings, government regulations (travel restrictions, border closures) have made it more difficult for these people to access jobs.

Analysis of Thermal Degradation in the Annealing Process of Colored Parts Built by Extrusion-Based 3D Printing
124-133Views:474With the ever-increasing request of light materials, poly lactic (acid) PLA, have got much in consideration. Low-cost PLA materials have risen its use. Those possess some benefits but nevertheless insufficient mechanical strength. The printed PLA objects have a stumbling block for practical applications. Thus, annealing is an interested alternative to make 3D printed objects strong. This thermal treatment can significantly develop investigational studies and offer technical data. Hence the purpose of this paper is study and discuss how to increase the flexural strength through annealing process. Geometry distortions and color degradation will be analyzed. Differential Scanning Calorimetry, Taguchi Method (TM) and variance (ANOVA) were applied as part of the design experiments and analysis. Twenty-seven printed specimens were tested and factors as temperature, time and color were selected.

Outlook of Precision Farming in Hungary
133-147Views:1516For agriculture, precision farming means the future by increasing incomes and reducing environmental loads at the same time Precision management produces a surplus in yield, revenue, result, but not immediately. The additional income potential is expected to increase by 20% to 50%. Farms mostly introduce precision farming in order to relieve workers. However, many farmers are afraid of the use of new technologies, but the use of information technology in agriculture will be unavoidable. Technology is fundamentally expensive, not even widespread, and farmers use only a few technology elements. Moreover, following the precautionary principle technology used in farming covers only a part of their agricultural land. So farms need to learn to produce more precisely than before in a knowledge-based manner.

Cybersecurity Challenges in Agricultural Digitalization: A Systematic Review with Python-Based Analysis
33-47Views:284The intersection of agriculture and cybersecurity has become a prominent research focus in recent years, driven by the rapid adoption of IoT (Internet of Things) and precision farming technologies. These technological innovations have revolutionized agricultural processes, enhancing efficiency and sustainability while introducing significant security risks. This study conducts a systematic literature review (SLR) to address key cybersecurity issues in agriculture, with a particular emphasis on IoT vulnerabilities and threats. Using Python-based text analysis techniques, the research automated the analysis of abstracts and full texts, enabling rapid filtering and thematic categorization of relevant studies. From an initial pool of 1,039 publications, 40 relevant studies were identified based on rigorous screening criteria. The thematic analysis revealed that 44.9% of the publications focus on IoT device vulnerabilities, 32.7% on agricultural cybersecurity challenges, and 22.4% on the security issues of Agriculture 4.0 and precision farming. Methodological analysis indicated that machine learning, simulation models, and case studies dominate the research landscape, while surveys and experimental studies appear less frequently. The findings highlight the critical importance of developing robust cybersecurity strategies and technologies in the agricultural sector, particularly to mitigate the risks posed by IoT devices.

Environmental Index and Environmental City Resilience Index calculation for Four Settlements in Szabolcs-Szatmár-Bereg County and Four in Győr-Moson-Sopron County
17-29Views:230Globalization and urbanization pose a number of challenges for different settlements. Stakeholders seek to cure global problems through sustainable projects. Since the Brundtland Commission's definition of sustainable development in 1987, the approach to sustainability has permeated all dimensions of the economy, including the environmental dimension. In Hungary, IBM conducted a study (Lados - Horváthné Barsi, 2011), in which the search for green, sustainable solutions defined in the definition of a livable city plays a key role. The characteristics of sustainable cities, that they are resilient to disasters, return to equilibrium after a shock has occurred (Seeliger, Turok, 2013). Resilience can also be mentioned as one of the pillars of sustainability. In a UN-Habitat statement, resilience refers to the ability of any urban system to withstand and recover from multiple shocks and to maintain the continuity of its services (OECD, 2018). In my study, I would like to present the results of the environmental index and the Environmental Urban Resilience Index (EURI) of the four largest cities selected on the basis of the population in the easternmost and westernmost counties of the country.

The Impact of Electrical Vehicles on Sustainability: Jordan as a Case Study
393-403Views:323The Global concern is moving toward making a revolution in favor of exploitation of renewable energy in order to improve environment conditions, limit emissions and minimizes consumption of non-renewable resources within the planet. In this context, it is necessary to focus on the transport sector as it contributes of at least 30% of the total primary energy consumption. Therefore, a set of rules must be developed to maintain economic, environmental and social sustainability to address the problems so as not to increase their severity and these cannot be done unless there are joint measures and regulations from governments, companies, manufacturers and users. Unfortunately, the Jordanian transport system mostly depend on the individual transport which supported by cars, and that because of the weak role played by the public transport sector, especially at the capital, Amman. Buying hybrid cars (internal combustion engine + electric motor) and Electrical Vehicles (EV), in the past few years in Jordan is increasing, which is compatible with the global trend to use Electrical Vehicles (EV) instead of Internal Combustion Engine vehicles (ICE) powered by fossil fuels, this issue will have a direct and indirect impact on gas stations companies, also it will have direct impact on labor sector and the current car industry since electric charging stations as well as EV manufacturing is not labor intensive. The main purpose of the study is to show how much it is necessary now to start theoretical assumptions through studying the expected annual increase in passenger cars and its impact on sustainability and predicting the future fuel consumption and emissions and compare them with the base situation.

Determination of the Differential Equations of a Dynamical System using Dual Description
41-48Views:148The paper deals with the description of a mathematical model of a mechanical system using the so-called energy-based approach. The model is created using both generalized displacements and generalized momenta. The latter prescription method is less common in practice, due to its complexity. The two ways are presented through the same example mechanical problem, and a control task is also solved with the help of a PID block.

Classification of Nanomaterial’s Risky Properties on the Aspect of Human Safety
34-45Views:283Due to their unique properties the application of nanomaterials continuously extends thus these appear for several industries. The industrial application of nanomaterials became significant during the last decades. As a result of the intensive development, our knowledge about the exact influence of nanomaterials for living bodies and human health is characterised by deficiency for both short and long time. Nanomaterials able to be entered to the living organism through several ways then invade to the circulatory system and the lymphatic system, reach the organs and can induce various kind of damages and serious diseases as a result of their different appearance, physical and chemical properties. Legislation in Hungary and in the European Union seems to be incomplete. There is no document which summarizes and details the risky factors and parameters in case of a risk assessment. Our aim was to develop a criterion system considering the risks related to the use and contact of nanomaterials based on their physical, chemical and biological properties, which criterion system could provide basic principle for a risk assessment thereby make the industrial processes safer both for the employees and those who are in the vicinity.

Floorball position and passive sports consumption in the light of a study
142-157Views:331Research and studies done on floorbal is usually associated with medical studies, however the research and analisys of other fields peakd little interest.Thus, the aim of the study was to present the situation of floorball in Hungary and to examine the opinion of passive sports consumers about the sport. Within this we deal with the competition system of our country and the organizational structure of the federation. In our primary research, from a viewer perspective, we were interviewed as passive consumers in a questionnaire survey about their relationship to floorball. In the questionnaire we discussed whether they had ever met this sport and whether they had seen it or what attracted them to the match. We also tested their willingness to pay. The results were compared with the opinion of one of the domestic leaders of the sport, which in many cases agreed with the results. The questionnaire was completed by 153 people, more than 95% of whom had heard of the sport and most had the opportunity to become familiar with floorball at primary school. 65% of those surveyed have already seen a live floorball match that they have mostly played with friends / acquaintances. This young sport can become more and more popular among young people, not only as a complementary sport.

Opinions of Higher Education Students about Internships and Working while Studying
286-297Views:515The importance of working while studying in higher education has a globally growing tendency, and Hungary is not an exception. The demand for the opportunities of student employment has been recognized not only by the students but also by the policy makers of higher education, leading to the introduction of solutions like the obligatory internship semesters or the dual training programs. The current study contributes to the better understanding of this field through the analysis of a database from a questionnaire survey conducted among bachelor students from seven majors of the University of Debrecen during the Fall semester in 2015 (N = 589). The main findings suggest that the students mostly consider the internships as an investment into their future career while the short term compensation and the personal interests have a lower importance for them. About 75% of the students would be willing to work not more than 20 hours a week, and most of them would look for ‘official’ studentwork. For working, they would sacrifice the time connected to the following activity-areas (relative to the other activities in the list, and in descending order): time for leisure (this is the most likely to be sacrificed), for sport, for friends, for family, and for learning (this is the less likely to be traded in for working hours). Willingness to work (measured in daily working hours) seems to be connected to the following factors: major, year of study, how important the activity areas are considered compared to working (learning, family, friends, sports, leisure), and the importance of finding a personally interesting internship.

Labour Economics - From the Technological Development Perspective
98-108Views:197The impact of technological advancements on the labor market and innovation processes is a critically important research area. The aim of this study is to examine the emergence and frequency of technological innovations in scientific publications, with a particular focus on the Journal of Labour Economics from 2000 to 2020. The research employs content analysis methods, searching for eight different terms and expressions related to technological development (e.g., technology, artificial intelligence, machine learning) across 1405 articles. The study also analyzes the number of occurrences and annual publication trends of these terms. A total of 9469 instances were identified, indicating that in 64,7% of the cases, at least one technological term appeared. An analysis of annual trends reveals an increase in the usage of certain keywords (technology, artificial intelligence, and machine learning). In a smaller subset of articles, only 1%, technological terms were mentioned at least 50 times. The results suggest that although the topic of technological development plays a significant role in labor market research, the frequency of its appearance and the depth of analysis vary considerably. The increase in the appearance of technological terms is predominantly observed in the fields of artificial intelligence and machine learning. These findings are specific to a single journal, indicating the need for further research involving other labor market journals to ensure representativeness.

Changes in the Financial Condition of Families in Hungary between 2000 and 2019
712-722Views:395The financial condition of families living on wages is function of many factors. It is determined, among other things, by the development of wages, social benefits, tax rates and the amount of allowances that can be granted. The part of the tax system that affects the largest segment of individuals changes every year, and even during the year, reducing predictability. In recent years, discussions over the taxes have shown that the rate of personal income tax cannot be evaluated separately from the social security contribution rate. Gross average earnings - on the grounds of raising the minimum wage and the guaranteed minimum wage - have more than four-times in nearly 20 years. However the rate of growth is higher in the average net earnings due to changes in the tax system. Compulsory determined wages increased to almost six-times over the years under investigated. But in 20 years, how much has the income situation of an average family living on a salary become more favourable or more unfavourable? In our study we are looking for an answer to how the increase in the minimum wage and the changes in the law how to have affected the livelihood.

Comparative Analysis of Equestrian Facilities in the North Great Plain Region
79-93Views:543Equestrian services appear in recreation, sports and tourism as well. The favorable natural and cultural values of Hungary and the image of the equestrian nation based on the traditions of the horse provide a favorable background for the development of supply elements. The lowland character and horse culture of the Northern Great Plain region, and the continuous development of horseback riding services here, reinforces the equestrian supply element in the field of sport and leisure. Our in - depth interviews were conducted among service providers with a “horseshoe rating” (N = 11) operating in the Northern Great Plain Region. The results show that all service providers consider and plan the development of equine, infrastructure and human resources, although the source of its financing is different (from state, other successful businesses, realized business results of equestrian enterprises). Equestrian service providers with no horseshoe rating have identified the improvement of quality, the 3, 4, and 5 horseshoe qualified service providers for the expansion of the complex program offering and product diversification.

Introduction to Design and Analysis of Torsional Vibration Dampers in Vehicle Industry
310-324Views:449The crankshaft of today’s internal combustion engines with high performance output are exposed to harmful torsional oscillations originated from the unbalanced gas and inertial forces. To avoid the fatigue damage of engine components, caused by the undesired vibrations, torsional vibration dampers can be applied. Viscodampers are one type of the torsional vibration dampers, which operational fluid is silicone oil. For cost-effective R&D activities and production, finite element and finite volume numerical discretization methods based calculation techniques must be involved into the engineering work supported by the modern computer technology. The aim of this paper is to provide an insight into the multidisciplinary design and development process of visco-dampers in vehicle industry applications. Four different examples as structural, fatigue, CFD analyses and structural optimization have been introduced in the present work. It turned out from the static structural and fatigue analyses, that the investigated damper has safety factor over the limit for both static structural and fatigue analyses, so it is suitable for the given load conditions. In the structural optimization process 34.36% mass reduction has been achieved. According to the coupled fluid dynamic and heat transfer simulations a rather stagnating air zone evolved between the engine and the damper during the operation, which can cause efficiency reduction of cooling fins mounted onto the housing. In light of the numerical results, the suitable damper position has been determined for the highest heat transfer.

Transportation System of Major Cities in the Middle East
50-53Views:197The quality of transportation has a great effect on the quality of our everyday life and the future of our planet. In contrary to Europe, transportation culture of the big cities in the Middle East region has grown fully different way. These Middle Eastern cities tend to have a different historical, traditional and structural background compared to other cities all around the world. One of these big cities is in the focus of our paper: Rijad, with 6 million inhabitants is the archetypal car dominated city of the Arabic world. We also elaborated a comparison to 4 other cities: Dubai as a city similar to Rijad, Amsterdam as a city with a modern green attitude, Budapest as a metropolitan city in Hungary and last but not least Debrecen which is a Hungarian city with moderate population. As a lesson learnt, we try to give some possibilities and outlooks for Rijad, in order to improve the structure of transportation.

The Factors of Digitality and Sustainable Competitiveness in the Domestic Context
217-226Views:277The recovery of international relations and the development of technology are in correlation with the increasing globalization tendencies. These processes increase the interdependence of countries, but also the competition between them. The factors of competition are constantly changing and being revalued. As a result new elements appear in addition to the traditional elements, and there are assimetries between existing components. The economic performance of a country increasingly depends on the knowledge and technology, its economic success on the use of knowledge. The purpose of the study is to present and analyze the proxies that define and shape the role of Hungary by IMD Competitiveness Research Center and by the complex indicators developed by Korea-based SolAbility. It also draws attention to all the factors that will significantly effect our country's economy in the future.

An Analysis of the Leisure Preference System of Students with Disabilities in the Light of a Study
98-115Views:840With the increase in the number of disabled people and people with disabilities, research on the target group of people with disabilities has gained momentum in recent decades. Research is very diverse, looking at the labor market situation of people with disabilities, their leisure-time habits, or the factors that support and inhibit their sport.
In our questionnaire research, the leisure and sporting habits of children with disabilities aged 8-18 are described and analyzed (N = 639). Data were processed with spss software, where basic statistics and contextual analysis were performed. The results confirm that passive activities (TV, listening to music) dominate the leisure activities of children with disabilities. Sports consumption (active and passive) was more prevalent among male respondents and less prominent among girls. In the motivation of sports, besides improving the state of health, entertainment and company appeared.

Strategic Role of Environmental Factors in the Operation of a Manufacturing Company: A Synthesis of Three Analytical Models
56-74Views:271Nowadays, the operations of companies are influenced by increasingly complex internal and external factors, the systematic examination of which is essential for conscious strategy-making. The relevance of this study lies in the context of global economic instability, rapid technological advancement, and intensifying market competition, all of which present new challenges for organizations. The aim of the research is to demonstrate how the analysis of environmental factors can support strategic decision-making, with particular emphasis on a specific company case. The analysis was based on three established methods—PESTEL analysis, Porter’s Five Forces model, and the SWOT framework—which together enabled an integrated examination of macro- and micro-environmental factors as well as internal resources. The results highlighted several key strengths of the company, such as professional expertise, international presence, and the quality of customer relationships, while also identifying several areas in need of improvement, particularly in terms of pricing strategy, digital information accessibility, and internal communication. The novelty of the study lies in the combined application of the three analytical tools, which revealed interrelated insights and served as the basis for well-founded recommendations aimed at enhancing strategic flexibility and strengthening competitiveness.

Markmyprofessor: the More the Better?
232-243Views:1302Student evaluation of faculty members is a current topic both internationally and in Hungary, partly due to the massification and partly due to the marketization of higher education. One of the evaluation methods is the internet-based voluntary rating which was started by ratemyprofessors.com in the U.S.A. and whose Hungarian counterpart is markmyprofessor.com. Research studies on the U.S. website – among many other critics – established that reliability of this evaluation method highly depends on the frequency of ratings: if an individual tutor is evaluated by more students, then the standard deviation of the ratings is smaller. The previous conclusion about the U.S. website is tested in our study based on Hungarian data. Our main result is that many of the experiences about markmyprofessor.com echo the previous findings about ratemyprofessors.com. Beside this in the Hungarian sample the higher response rate is associated with lower average ratings.

The Role of Renewable Energy Sources in Energy Production and Use
678-688Views:396The role of renewable energies in energy management is growing both in the European Union and in Hungary. The use of renewable energy sources is already quite large (transport, heating, lighting, etc.) and it is advisable to deal with these energy sources in the year 2020. The use of energy from renewable sources can reduce greenhouse gas emissions and reduce dependency on the continuously problematic oil and gas market. A review of energy data over the last 10 years shows that renewable energy sources are playing an increasingly important role in the European Union. I support this finding by the fact that the share of energy from renewable sources in gross energy consumption has almost doubled in the last few years.

Optimizing the combustion processes of a small scale solid fuel-fired boiler
358-369Views:238Over the last decade, the public has been paying increasing attention to reducing greenhouse gas and acid rain emissions and reducing particulate matter, which is extremely harmful to health and the environment. To improve air quality, the European Commission has achieved a range of measures to reduce air pollutant emissions in the transport, heat and electricity, industrial and agricultural sectors. In Hungary, the amount of gas and solid air pollutants from solid fuel combustion used by the public during the heating season represents a significant percentage of the total amount present in the atmosphere. In 2016, taking into the total emission, the 29% of CO2 emissions; 85% of CO emissions; 75% of the particulate matter emissions and 21% of the NOx emissions were derived from households. It follows that the improvement of air quality can also be achieved by controlling the emissions of solid fuel combustion plants. During our research we aimed to optimize the operation of a newly purchased TOTYA S18 boiler and a pilot pellet boiler. Operating the boilers in the correct mode minimizes air pollutant emissions, and the greater part of the heat generated is actually turns to heating the home, as with poor settings, a lot of heat leaves through the chimney. The data obtained during the tests can also be used to determine whether the boilers comply with the emission values set out in Commission Regulation (EU) 2015/1185.
