Visual Analysis and Geometric Modeling of Metal Foams
89-92Views:190The development of an efficient procedure for 3D modelling and finite element simulation of metal foams
is one of the greatest challenges to engineer researchers nowadays. Creating 3D CAD model is alone a demanding
engineering task due to its extremely complex geometry, and the proper finite element analysis process is still in the
center of the research. The aim of this project is to analyze the related literature and to adapt the results may be
considered. -
The Effect of Player Transfers on Football Companies Valuation
Views:433Transfer seasons are one of the most highlighted periods in world of football. The market of player rights forces the greatest european clubs with their enormous budgets to compete with each other in order to aquire the most talented and most succesful players. It is not uncommon to sign players for tens of millions of euros, to this extent these expenditures are seriously affecting clubs bottom line. However, despite the expenditure nature of player transfers the value of these clubs increase, based on the best known measurer for companies valuation: the stock exchange. In my research the effect of player transfers ont he valuation of football corporations are presented through market value development of stock market listed clubs namely Juventus and BVB Dortmund. Based on my results if the examined clubs were signing players according to a player transfer policy considered as succesful the value of examined clubs had increased through stock market price independently of player transfer balance. Moreover the effect of coronavirus could had been noticed, since both clubs valuation decreased heavily in the 2020 summer transfer window probably due to the revenue loss caused by the pandemic.

Influence of MTP on Surface Roughness and Geometric Accuracy of Machined Surface at WEDM
91-97Views:256Electrical discharge machining technology is one of the most precise machining methods. Therefore, even the smallest deviation of micro and macro geometry generally has a significant impact on the overall quality of products produced by this progressive technology. The quality of the machined surface after Wire Electrical Discharge Machining (WEDM) is influenced by a large number of factors, most of which are influenced by the Main Technological Parameters (MTP). The aim of the paper was to describe the results of experimental research aimed at assessing the impact of MTP for WEDM on the quality of machined surface in terms of geometric accuracy and roughness parameters Ra and Rz. The samples were made of high alloyed ledeburitic chromium-molybdenum-vanadium steel designated EN X155CrVMo12-1 on a Sodick AQ535 electroerosion machine. The tool used was a standard compact brass wire 0.25 mm with the designation Elecut Brass CuZn37.

Why do not people attend football matches in Hungary?
11-22Views:457Both international and domestic research on passive sport consumption focuses on the motivations of fans. However in Hungary, unlike the examples of North America and Western Europe, we have to look for answers to the question of why people do not go to football matches. In order to find an answer to this question, we conducted an online survey with a number of items of 347 people. For the latter a scale measuring absence from sport consumption was used and the reliability of the scales was tested by Cronbach's alpha calculation. After our principal component analysis, we developed 5 internal and 5 external factors, on which we conduct hypothesis test along demographic and sports consumption variables. Based on our results, we have established that, contrary to public opinion, the low number of spectators in Hungarian football matches is not only and primarily due to unsucces and the low quality of matches. Our respondents are mostly kept away from stadiums by football-related government measures, as well as by preferring to participate in other recreational program opportunities.

Examination of road sections in Debrecen by noise mapping
287-295Views:184During the research, noise level calculations were performed for 13 numbered roads in and around Debrecen and a noise map analysis was conducted on the roads’ environment. The first examined year was 1995, the last was 2017. In the time interval, annual status was determined based on average daily traffic data. In addition to the road noise values calculated for each section, a noise map was prepared for each survey year. For the evaluation of the results a difference map of the highlighted periods was prepared. Typically, noise level increase from road sources was identified between 1995 and 2017 in a significant part of the studied area (southern and eastern parts of Debrecen and around the newly built roads). Stagnant noise level was diagnosed near the downtown of Debrecen and around the main road No. 4, furthermore in some places noise reduction was caused by the development of the road network (between Debrecen-Józsa and Hajdúböszörmény, between Debrecen and Látókép around road No, 33, and along roads No. 4808 and No. 4814) .

Material Stock and Flow Analysis within the Agricultural Building Sector Based on Local Database
297-320Views:241The purpose of the paper is to analyze on micro level the stream of building materials needed for raising cattle. The scope of the produced material flow chart will cover the inflow and storage of the materials. The overall objective of material flow analysis is to contribute to the data inventory development process which is needed to use these construction materials as secondary raw materials in the future. The assessment is based on a concrete new development in a Hungarian region being carried out nowadays as a development and modernization of an existing cattle raising farm. Driven by the concern of resource depletion, further research on higher level, based on larger database will be needed to verify the estimated national level results for the magnitude of growth of anthropogenic stocks.

Perceived Barriers to Youth Entrepreneurship in Pakistan and Hungary
382-391Views:248Entrepreneurship brings enormous benefits. It generates employment and helps in social and economic development. Ventures created through the youth entrepreneurship have enormous benefits. They generate employment, reduce poverty and unequitable distribution of wealth. These ventures do also help in social, economic and technological development. However, the youth faces several barriers to entrepreneurship. This study explores the personal & psychological, family related, institutional & regulatory, cultural & social, financial and market & knowledge barriers faced by the youth of Hungary and Pakistan. Qualitative research methodology was applied. Interviews at micro and meso levels were conducted from the young entrepreneurs and university professors of Pakistan and Hungary. Results indicate that Pakistan and Hungary have almost similar levels of Personal & Psychological barriers, however, the fear of failure is higher in Hungary than in Pakistan. Family related, cultural & social and market & knowledge barriers are higher in Pakistan for the youth entrepreneurship than Hungary. Institutional & regulatory and financial barriers are at medium levels in Pakistan. For Hungary, these are at low levels. The study has important implications for researchers, academicians, policy makers and for the young aspiring entrepreneurs.

Application of Team Coaching Tools for University Education – Case Study
445-456Views:630In 2010 the innovative Finnish higher education system (Tiimiakatemia – Team Academy) was launched at University of Debrecen Faculty of Economics and Business, which was also awarded by OECD and has been run at JAMK University of Applied Sciences in Jyvaskyla since 1993. In this system, we create team entrepreneurs who have to work together in teams. In this research the authors would like to look at how we can use the team coaching tools as a part of this model in our team entrepreneur education system to build high performing teams. Tuckman named five stages of team formation: forming, storming, norming, performing and adjourning. A new team cannot be expected to perform as an excellent team when it first comes together. It takes time forming a team, and they often go through recognizable stages as they change from being a collection of strangers to a united group with common goals. You have to understand it at first, than you can help your team become effective more quickly. Authors of this study work as team coaches in Team Academy Debrecen. In the last 6 years we have worked with several teams and experienced how group dynamics present at the teams and change through the learning process. We have faced with great storming period at different teams and managed to build high performing entrepreneur teams as well. Our experiences are introduced as case studies, after analysing, consequences will be concluded. As in the EFQM model we can find that to survive in the global competitive markets companies need the best teams for the best results.

The Relationship Among Ethics and Conflict Management in Hungarian Metal and Machinery Supply Chains
1-18Views:181It seems that ethics has become an important issue because more and more firms accept ethical codex and make them public as well. On contrary all of us know some stories when unethical behaviour resulted tragedy. Nowadays in business life ethics and responsibility appear as necessary value from the aspect of success. More papers state that ethical behaviour offers various benefits in business relationships. Our paper seeks these positives in empirical way by interviewing members and experts of Hungarian metal and machinery supply chains but we take into consideration the network effects as well. Our survey investigates how fair behaviour can prevent or decrease conflicts in business. The results of our qualitative research show that fair behaviour brings certain benefits but the economic reality and the direction of money flow are dominant. We have met various forms of conflict management and found that respondents want to maintain even very problematic business ties as well.

Servant, Ethical and Authentic Comparative Analysis of Leadership Styles in the Light of the Challenges of the BANI World
43-52Views:290In a globalised and accelerated economy, managers are under increasing pressure to reconcile organisational goals that are independent from human being with the reality of human relationships. The human being, as a being with intellect and senses striving towards happiness, is the focus of positive leadership styles and is their major concern in the field of management theory. In this article, three such positive styles, authentic, servant and ethical leadership principles and their operating conditions are compared using international literature. The literature time span of about two decades shows that the evolution of the ethical leadership literature has slowed down, while the authentic and servant leadership literature has continued to evolve and is still evolving today. The comparative table that appears in this study highlights both commonalities and distinctions, in that, in addition to high moral and ethical standards, the authentic style focuses primarily on the person of the leader, the ethical leader on the ethical standards of the organisation, while the servant leader focuses on the development of the well-being of the subordinate, the other person, even through self-sacrifice. We intend to use the results of this research to investigate measures of positive styles, preparing the scientific ground for future primary empirical field studies.

The Role of Employee Participation and Resistance in the Success of Change Management
22-30Views:615Successful change in the lives of organizations has played a particularly important role in the recent turbulently changing decades, and leadership-follower relationships need to be addressed in order to maintain performance. Participation should be ensured for members of the organization and emerging resistance should be addressed. The subject of my research was to examine whether the assessment of the success of change is influenced by the provision of opportunities for employees to make suggestions and their opposition to change. By performing chi-square tests, I came to the conclusion that if the opinion of the worker is heard, they are more likely to judge the change to be successful, however, the manager is not affected by the involvement of the employees in this. However, there is a correlation between employees' resentment to change and the success of change, both from the employee and managerial side, change is more unsuccessful if resentment develops. Based on the results, both factors are important. It is worth drawing the attention of managers to the need to ensure participation, as failure to do so can lead to dissatisfaction among employees, which can also have a negative impact on the success of the organization.

The Evaluation of the Employment of Migrants by Employees
102-114Views:265The exploration of specifications of the employee groups endangered in the labour market, and their social
and labour market integration have always been a challenging task for the professionals. As a result of the
domestically also appeared migrant wave, the actuality of the topic has even more increased. In this study -
prepared in the framework of the research program „Human resource management challenges of the reception and labour market integration of the migrants” - we aimed to reveal the attitudes of employees about the labour market integration of the migrants. We have defined an objective to explore whether they are afraid of losing their current jobs, what factors influence the employment of the migrants and what kind of positive and negative effects they take on the society and economy. Based on the results of the survey we have found that employees are not afraid of migrants taking their jobs, still they are quite uncertain whether they would employ or work with a migrant person. Regarding the effect on the society and economy an unambiguous negative attitude was experienced. -
Employment Challenges in the Second Wave of the COVID-19 Virus from a Corporate Perspective
152-163Views:756The changed market conditions caused by the Covid-19 virus forced companies to rethink their strategy and structure and to optimize their processes. The aim of my research is to shed light on the changes in the second wave of the coronavirus epidemic that have had a significant impact on the operation of businesses and presented them with significant challenges. For the study, I used the results of a previous questionnaire survey (Pirohov-Tóth 2020; Pirohov-Tóth, Kiss 2021), which were supplemented with a literature analysis and statistical data from the database of the Central Statistical Office. Furthermore, compared to the first wave of the virus, I examined how job productivity changed in the second wave of the virus. Finally, corporate crisis management options have been presented in my analysis, the practical application of which can contribute to re-emerging from the crisis. It can be stated that the acceleration of digitization and the widespread expansion of advanced technological tools and methods can be considered as one of the biggest positives of the viral situation, which can also mean survival for companies in this pandemic situation.

3X3 Basketball Tournaments in Debrecen
231-250Views:371Faster attacks, spin speed, increased adrenaline levels, vehement play. This is all about the 3X3 basketball. In Debrecen, the first 3X3 basketball matches were held in 2015, most of them did not even think that the sport would be popular in Hungary as well. Practically, from the start of the first minute, the games were played with great success. Following the successful settlement, the International Basketball Association immediately offered a 3-year contract to Debrecen. The purpose of our research was to examine the 3X3 basketball tournaments in Debrecen, which was analyzed using a questionnaire and an in-depth interview. 69% of the respondents participated in the 2016 and 2017 events, but only 37% attended the 3X3 basketball tournaments that were held for the first time in 2015. It can be stated that this trend is growing and the event is gaining popularity nationwide. Sponsors and sponsors covered every issue of the event so the event was free of charge over the years. 72% of fillers, however, are willing to spend money on a possible entry fee. In terms of revenue growth, the introduction of admission fees is unlikely to reduce interest. Up to 1200 seats have been filled up for the event every year. Therefore, it is not surprising that a lot of people would like to enjoy a higher auditorium with more space. The introduction of 4-point boundaries (3 points) for 3X3 matches would be a great opportunity to try the "little brother" of basketball in the 4-point so that it can be introduced in traditional basketball. Hungary became the pioneer of the sport due to the results of the Hungarian national team and the successful organization of sporting events.

Investigation of SCOR Model in Connection with Performance and Warehouses
227-239Views:264Business leaders can use several strategic tools to improve the organization, depending on what they consider to be important. The Supply Chain Operational Reference Model (SCOR) is one of these. Its importance is to link business processes, performance metrics, best practices, and technology together and to create a unified structure. It promotes communication between the stakeholders of the supply chain and improves supply chain management and the efficiency of the related supply chain improvement activities. The aim of this study is to find out how the SCOR model appears in the international literature related to warehousing and performance. What methods and tools do authors use to investigate their research questions and hypotheses? Description statistics and category selection were used to present the results of the study. The number of SCOR model researches related to warehouse performance measurments are very rare, it is rather used to describe different processes. In the future, it would be worthwhile to extend the SCOR model analyzes to further fields, especially to warehouse performance measurements.

Comparison of R&D innovation indicators of the visegrád group
162-172Views:171Innovation is a crucial strategic issue not only for businesses to maintain and improve competitiveness, but also has paramount role at a macroeconomic level how a national economy is able to contribute to the national division of labour. Innovation and research and development are particular and even more crucial in post-socialist countries which are trying to catch up with Western Europe in an economic point of view. We compared countries in the Visegrád Group in the study regarding their innovation indexes, R&D indicators and corporate innovations. These indicate that countries in the Visegrád Group are lagging behind the European Union. The Czech Republic ranks the first place in almost each aspect among the countries in the Visegrád Group. As for time series indicators, there is a steadily improving tendency in R&D. Regarding measuring innovation and R&D, it can be concluded that perfect method and scorecard are not available, indexes based on varying methods may generate different results and decision taking only one index into consideration cannot be made in business practice. In my opinion, R&D indicators are dominant to a large extent in comprehensive innovation indexes that might be misleading in the assessment of innovation (particularly in corporate innovation).
