Simulation of BLDC Motor Drive Systems for Electric Vehicles Using Matlab Simulink
48-52Views:570The defining scientific developments of our time would not have been possible without the use of simulations. The aim of the research is to create a simulation of a BLDC motor. When creating a simulation, great emphasis must be placed on defining the purpose of the simulation. This basically determines the structure and complexity of the model. The model discussed here was created so that an optimization task could be defined more precisely by inserting it as a sub-model into a vehicle dynamics model. Scalability was another aspect, that is, to be able to increase the accuracy of the model with measured data in the future, as well as to be able to validate it. During the research, a BLDC motor efficiency map generation program was created, as well as an environment for testing the generated data. The created system gives researchers the opportunity to use a shape-correct efficiency model when simulating a BLDC motor even without measured data. This makes it possible to discover real relationships between model parameters when performing optimization.

Long Container Dwell Time at Seaport Terminals: An Investigation Study from a Consignee Perspective
Views:841Many companies are concerned about the problem of increasing average dwell time for their import containers at the port of the final destination and therefore incurring additional shipping costs in form of demurrage charges for the port administration and detention charges for the shipping line. Previous studies have addressed this topic by analyzing terminal operations and evaluated its effects on port productivity and competitiveness; however few studies have explicitly explored long container dwell time causes from a consignee perspective. This research aims to identify the causes of long dwell time for the import containers at port storage yards for one of the leading FMCG companies in Jordan. To that end, the data of import containers whose stay at the terminal exceeded the free storage days in the period between 2019 and 2020 were collected by referring to the set of shipping documents and reviewing the correspondences between the consignee and other parties in the supply chain. Based on the timelines that have been analyzed for each case of delay to the collection of shipping documents in consideration with the payment terms, as well as the clearance and delivery timelines, ten causes for the long container dwell time have been identified and classified into three main categories according to the types of flow in the supply chain; five causes related to information flow, two causes related to cash flow, and three causes related to physical flow. The impact of these causes has been evaluated using the demurrage and detention charges as a measure indicator and the findings of this research have also revealed that the causes related to cash flow have a greater impact than the other types of causes.

Labour Economics - From the Technological Development Perspective
98-108Views:267The 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.

Improvement of High Strength Automotive Steels Wettability Properties Using CO2 Laser Surface Treatment
422-427Views:294As a result of stricter environmental and safety standards, vehicle manufacturers have to reduce the weight of the vehicles, because 10% weight loss cause 8-10% reduction of fuel consumption. To reduce car’s weight and increase safety, vehicle manufacturers use high-strength steels. Further weight reduction can be achieved by using corresponding bonding technology (soldering, sticking) and optimizing these technologies can increase the strength of the joints. According to literature research, the improvement of interface properties has a large effect on bonding technologies. In order to improve interface properties, we can use multiple surface treatments. In our research we investigate the effects of CO2 laser surface treatment on high strength steels, because CO2 lasers are often used in the vehicle industry. In order to detect the effect of surface treatment, we investigate the wettability of the treated and untreated steels. In our research we measure the surface tension of treated and untreated steels. Our main goal is to improve wettability properties thus the bonding technology. In our research we used DP 600 high strength steel sheet with the thickness of 1 mm. We cut the steel sheet to 25mm wide and 55mm long workpieces. Before the surface treatment, the workpieces had to be cleaned and degreased using methanol. We searched for parameters that do not cause any visible changes on the surfaces. Among the parameters of the treatment we were able to change the output power of the laser. We used contact angle measurement to examine the wettability.

Entrepreneurial Climate – Management of Women's Entrepreneurship
69-74Views:238Entrepreneurship, which people can have without formal economic education, is a tendency acquired through upbringing in the family, competition in school, implies risk and constant self-affirmation through the acquisition of profits and losses, so that it represents the sum of successes and failures, victory and defeat. In the last thirty years, female entrepreneurship has been developing more and more, especially in less developed countries, the reason for such growth is primarily reflected in the promotion of equality between men and women, the right to education, and the development of democracy. Female entrepreneurship is a significant factor in economic development, so the national economy becomes richer. The subject of this research are the entrepreneurial climate in the Balkans compared to the world in terms of female entrepreneurship, what is the role of the family in starting a small business, as well as its survival and growth. In the study the results of previous research in this area. The research method is based on a comparative analysis of studies dealing with this problem from the territory of Balkans. It can be concluded that in the Balkans, female entrepreneurship is still in its infancy, it is about a very small percentage of female entrepreneurs, although according to research, it is evident that there has been no major progress in the last 15 years. Recommendation In the countries of the Balkans, there is a good entrepreneurial climate for the development of female entrepreneurship, especially because women can work from home, and in the future it is necessary to go in this direction.

Applying New Innovative Market Research Methods in the Innovation Process of New Products
56-69Views:374The innovation environment has changed a lot in the recent years, companies and their enterprises concentrating on product- and process innovation have undergone a lot of changes. According to GUPTA et al. (1986) product innovation is a multidisciplinary process. Although, all functional interfaces are important in the product development process, the research and development – marketing interface is one of the most difficult one. In the last two decades the incredibly fast penetration of the internet has more and more effects on the consumer attitudes. It encourages market researchers to apply such methods by which they could get as close as to the consumers to know their attitudes without taking them out of their natural habitat. In this study our aim is to concentrate on the first phase of the product innovation, which is the exploration of insights and attitudes. In this phase we can use the classical, conventional market research techniques if we want to get primary data, such as focus group interviews, questionnaires, in-depth interviews, but there are new methods as well. One of such novel methods is netnography. The biggest advantage of this research method is that the researcher can observe the consumer groups’ state of mind and decision-making mechanisms through publicly available communication sources in their natural environment. In this study it will be analysed how the directions of netnographic researches have changed by the dynamic changes of the internet. Besides, online participants’ attitudes towards healthconscious nutrition are analysed in practice. As a result of this study, special groups could be identified, which can provide a new perspective for the companies operating in this field beside the classical segmentation techniques. These groups can be the ones which draw up latent market requirements, and thus, helping the companies’ innovation processes.

Examining the employees and sectors of the economy according to the digital competence in the EU memeber states
344-357Views:415In this study, the challenges of digital development and its sectoral effects were examined between 2015 and 2017 in the EU Member States, based on data of OECD, Eurostat, and the World Bank. The connection between the countries' digital development and sector dominance was analyzed. I found - in line with international research - that in countries that belong to the developed group, the high value-added service sector is dominant. The statistics of developing countries’ supported the assumption, that industry is the engine of the economy. The analysis of the underdeveloped countries revealed that agriculture and industry are the most important sectors compared to other countries. Measuring the demand of developed countries for ICT professionals, I examined the relationship of individuals with different digital competencies to one kind of self-education. In line with international research, my database showed that digitally unskilled people are the least likely to take advantage of online courses. As a continuation of the research, it would be worthwhile to carry out this study in other economic areas as well. Especially in areas where salaries for high-digital occupations do not differ significantly between countries in the region.

Investigation of Parental Roles in Relation to Youth Football
105-114Views:381My research is based on the fact that, thanks to the development of sports and the capital flowing into the sector, youth sports are no longer just a useful way of spending free time for children and a mean for educating them for a healthy lifestyle, but also an opportunity to lay the foundation for an adult sports career and, with it, secure future existence. In order for the training to be effective and productive, one of the many components is the existence of parental support. Youth competitive sports pose many challenges for a family and influence their lives from several aspects. In my research, I examined how youth sports affects parents in terms of certain demographic variables, what changes it generates in their family life, and I also paid attention to what expectations the family has about sports. The basis of the study is an online questionnaire survey, which was filled out by more than 700 parents of youth football associations. My research revealed that, in accordance with the previous literature related to the topic, their children's sports have a significant impact on the lives of the parents and they set different expectations regarding it, which are also influenced by various social and demographic factors.

Assessment of the Working Ability of Persons with Disabilities and Reduced Work Capacity
36-52Views:846Employment of persons with disabilities and reduced work capacity falls significantly behind that of non-disabled persons both in our country and the European Union. According to research findings, the low employment rate is partly due to discriminatory attitudes towards the group of employees concerned. In the labour market integration, apart from the attitudes of the employers, the approach of the employees working for the institute has also got a significant role, as they are the ones who as colleagues work together with persons with disabilities and reduced work capacity day by day.
The research findings presented in this study focus on the research question whether the 747 employees who participated in the questionnaire survey make a distinction between persons with disabilities and persons with reduced work capacity on the grounds of their ability to work. If so, what kind of differences are noticeable and what factors have a positive impact on their approach? What is characteristic of the employees with higher level of inclusive attitudes?

Investigation of Zeta Potential of Water Based Nanomagnetite-Bentonite Dispersions
54-66Views:307The stability of different type nanomaterials play an important role among recent scientific and industrial
challenges, including the examination of the effect of polymers, surfactants and their mixture on surface and electric surface properties and aggregation extent of dispersed particles, which are of utmost importance. Bentonite and its composite with different nanomaterials are frequently used for instance in environmental protection for wastewater treatment, since due to their great specific surface area they have excellent sorption properties. There are several publications in the literature for the application of bentonite in drilling muds. By using them the fluid loss can be decreased during the drilling process, the filtration of the fluid can be increased, it also improves the rheological properties and the formation damage can also be mitigated. During research the investigation and the analysis of the zeta-potential of nanoparticles and their composites at different pH and salt content can be an interesting topic. During our experiments the electric surface properties of nanomagnetite synthetized in laboratory (NM), cation
exchanged bentonite from Mád (Be) and the composite particles of these particles were investigated. Hybrid particles of different compositions (9:1, 7:3, 1:1, 3:7, 1:9) were analyzed at different potassium chloride concentrations (0.1 – 0.0001 M). The surface adsorption on the surface, i.e. the change in the surface charge can be traced well by analyzing the obtained zeta-potential values. The behavior of such systems was observed in the full pH interval, thus, valuable data were obtained regarding the colloidal stability. As for the stability, different requirements may emerge in practice, there are application fields where the colloidally stable system is advantageous, on the other hand, in some cases, ceasing the stabile system is the goal. Our investigations are of high importance in terms of stability and its characterization. -
Dual Focus of Supply Chain Resilience and Sustainability: A Size-based Comparison between SMEs and Large Organizational Approaches
1-15Views:319The research investigates how organizational size influences the implementation of supply chain resilience and sustainability practices. While resilience and sustainability are increasingly recognized as interrelated priorities, existing literature often overlooks how firm size conditions strategic behaviour, particularly the distinct constraints faced by small and medium-sized enterprises (SMEs). To address this gap, the study employs a two-phase, mixed-methods approach. First, a structured literature review identifying the current state of academic research on the field. Second, a global survey of 252 supply chain professionals captures quantitative data across SMEs and large organizations. Statistical analysis tests three hypotheses regarding core aspects of driving resilience and sustainability outcomes. Findings show that large firms tend to formalize strategies more thoroughly, especially in risk detection and sustainability goal setting. However, SMEs demonstrate comparable resilience through informal, agile approaches and supplier collaboration. Overall, strategic effectiveness does not vary by firm size, but implementation pathways do. This study contributes original empirical evidence to the limited comparative literature on organizational size in supply chain strategy. By introducing size as a moderating variable, the research advances theoretical models and highlights the need for differentiated tools, policies, and partnerships. The findings aim to hold practical value for managers, and support businesses seeking to design scalable, inclusive approaches that enhance resilience and sustainability across the entire supply chain spectrum.

Extreme Sports Consumption Implications from a Re-search
135-145Views:984Nowadays, more and more research focuses on recreational sports consumption, its motivational background, the determination of target group characteristics. Extreme sports are becoming more and more prominent in leisure sports and are increasingly represented in competitive sports. In our research, we are dealing with Extreme Sports Consumption, Questionnaires were collected in the form of a Google Survey, an online questionnaire survey, which was divided into groups of people who focused on individuals with a variety of social media and targeted extreme sport interests. Data was processed using IBM SPSS software, basic statistics and correlation analysis. Our results were also graphically illustrated. After data deletion, we processed 167 questionnaires. The results show that men prefer extreme sports. Our study shows that in Hungary, the most popular recreational extreme sports are cross cycling, rock climbing, mountain bike, paintball and skateboarding. Among young people with higher incomes, there is a significantly higher proportion of extreme sports consumption. Because expensive sport thus assumes higher discrepancies in income and higher spending propensity, which is confirmed by our research. The brand selection of sports equipment for young adults with extreme sports is not characterized by extreme sports-specific brands, but by classic market-leading sports brands (Nike, Adidas).

A Best-worst Scaling Usage in Marketing Research
140-151Views:270Best-worst scaling (BWS) is a method of data collection and / or a theory of how respondents give the first and worst rankings in a list. In my article, I look at what best-worst scaling (BWS) is, what areas it is used to, and what the method itself is. I then turn to the BWS method, within which I examine its element: the BWS object case (case 1), the BWS profile case (case 2), and the BWS multi-profile case (case 3). I will detail the use of BWS in marketing research, and then compare the Likert-scaling method and BWS. I summarize my conclusions at the end of my article.

Challenges of the Quality- and Change Management in the Context of Upcoming Social-Industrial Changes (5.0) – Conclusion of a Survey
138-150Views:363The upcoming industrial-social revolution, which may be called the 5.0, is emphasizing the coordination of the value-creating work of technology (machine) and man. This approach wishes to move towards sustainability, which deserves a significant role in nowadays through the world empathizing the negative effects of the wolrd. During my research I was looking for the answer that how the extended industry 4.0 and its tone be in Hungary via supply chain of the automotive industry. During my research I was looking for the answer that how the extended industry 4.0 be in Hungary and its tune through supply chain of the automotive industry. I also have examined that which changes are justified regarding management systems in interest of efficiency and emphasizing the human capital by leaders interviewed. As a part of qualitative research in-depth expert interviews were interpreted with help of content analysis based on the methodology of grounded theory. The results demonstrate the need to review and change existing processes in order to ensure that the potential of human capital is not lost and that technological development, even more so, is at the service of human resources in order to achieve its efficiency and effectiveness. Among the possible tools we can find the re-structurizing changes of post tracking processes of the audits in management systems providing quality. Furthermore, the practical implementation of multifactorial statistical process control in the evaluation of processed data, which may be one of the essences of industrial (IoT) data.

Analysing the Possible Connection Between Dark Triad Personality Traits and Ethical Attitudes of University Students
57-67Views:493In our paper we examined the possible connection between the Dark Triad personality traits and ethical attitudes among university students. The analysis of both topics has become the focus of interest in the past decades. Researchers consider the impact of many factors in the background of ethical attitudes and behavior. Among other things, personality is also a potential factor. The Dark Triad personality means the coexistence of the socially undesirable narcissism, Machiavellianism and psychopathy. Such people are characterized by self-love, aggression, the lack of guilt or conscience, so they are less likely to have ethical attitudes. In our research, this connection was examined by a questionnaire survey conducted among first year students of University of Debrecen Faculty of Natural Sciences and Technology and Faculty of Economics and Business. Respondents completed the validated Dirty Dozen questionnaire which was developed to measure Dark Triad personality and a questionnaire adapted from Lozier's research in which respondents were asked to evaluate school situations whether they are ethical or unethical and to what extent they are unethical. In our research, we were looking for significant relationships between the strength of the Dark Triad characteristics and the ethical judgment of situations. We also analyzed the differences between men and women and students of the two faculties.

Digitalization Process by Agricultural Companies, or the Results of a Questionnaire Survey
625-636Views:397The term “information society” first appeared in Japanese social science in the early 1960s (Z. Karvalics, 2007). The interpretation of the concept has undergone significant changes over the past decades, showing that dynamically developing societies, which are undergoing constant changes due to the rapid development of information, information management and the dynamism of the digital world. The close relationship and connection between information and information technology has become a fundamental factor in the societies of today, the organizations life, which generates inevitable, sometimes serious debates and profound changes. Economic operators must necessarily be resilient to technological change. We should think of the time of the Industrial Revolution, when modern weaving machines flooded the factories. Otherwise, a resilient organization will not survive in an evolving and ever-changing dynamic economic environment. Of course, this is true of agriculture as well, just as it is for other sectors of the national economy. On the one hand, my assumption on the basis of which my questionnaire was compiled was that enterprise management systems are increasingly used by enterprises in agriculture due to the diversification of activities. At the same time, I assumed that the size of a business could influence the use of information technology (hereinafter IT), so I hoped that my research would provide reliable data on this as well.

Digital Twin and Shadow in Smart Pork Fetteners
515-520Views:456This paper introduces our ongoing research in the field of smart livestock farming. The base idea in this research is to take some industry based concepts, and adapt them into agriculture. In Industry we live the fourth industrial revolution, which is not a technical, but an organization revolution. So in this concept there are two key ideas, which are digital twin, and digital shadow. This article is about creating digital twin and digital shadow of a modern pig fattener. These models are based on the literature, and are identified on the data shared in these. However, these models can’t be used on real systems before identifying them on the actual circumstances. At this stage of research only digital twin of the product was created, and only some aspects of it. This however can simulate an average porkers feed consumption, weight growth and calculate the weight on certain stages of breeding. Further development is ongoing and our target is to make a fully functional model of a pig fattener.

The Middle East perspective of Corporate Social Responsibility
282-291Views:494Corporate social responsibility (CSR) in the Middle East is gaining more importance than in the past. Although it still remains more about philanthropy and charity, it moves towards a more strategic approach which includes formalizing ways of giving, as a set of non-random actions, and focuses more on addressing social ills and environment, economic challenges, that are hindering development. However, the business in the region has not yet taken the step to fully integrate the CSR into their core business operations. The most common challenges that facing the CSR implementation are the lack of government requirements and incentives, spreading awareness, building CSR partnership model, going beyond the marketing and PR campaigns, and full integration of CSR into the business strategy. In this paper, we aim to introduce the current state of the CSR in the Middle East and its perspectives, besides reviewing its evaluation stages, motivations, and current challenges. Moreover, we aim to examine CSR common practices through examples from the financial sector. The research method applied in this research is based on secondary data sources and we have used desk research to illustrate most important points and findings on the topic.

Floorball position and passive sports consumption in the light of a study
142-157Views:374Research 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.

Analysis of labor consumption in Hungary in the last 5 years
127-137Views:290The 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.

The Appearance of Dark Triad Among University Students
579-588Views:431In recent decades, the examination of the so called “Dark Triad” – narcissism Machiavellianism and psychopathy – occupies a prominent place in personality research. These socially undesirable characteristics, which, to some extent are present in everybody, can play an important role in the workplace. Dark Triad members are those, according to the literature who are strong in all three features. In my paper I will present the results of a study I conducted among the students of University of Debrecen Faculty of Economics and Business. I analyse the Dark Triad characteristics of students with the help of a validated measure the Dirty Dozen. In my research I try to find answer to what extent these personality traits appear in the examined sample? Is there any difference depending on the background variables (age, sex, educational programme ...)? Are my results consistent with those described in international research?

Study on Learning Motivation of Master's Students in Management and Leadership at the University of Debrecen
69-79Views:280The aim of our study is to present the topic of adult learning. To do this, we first define the definitions and importance of learning in a person’s life. We then turn to the historical background and evolution of adult learning. The motivation of adult learning as a function of different motivational theories is presented. In the second half of the study, an initial research focusing on the motivation of adult learning is presented. The subjects of our research are young adults who are pursuing their master's degree in management and organization at the Faculty of Economics of the University of Debrecen. We want answers to the extent to which different factors motivate young adults in studying. With the results, we want to give an idea of how the learning motivation of the students can be characterized by both lecturers and human resource professionals working in the private sector. We intend to expand the research to a larger sample in the future.
