    Digitalization and the explosive development of technology have led to significant changes in football. Due to the increasing amount of data available through various sensors and other data collections, we can observe the rise of data-centric, analytical and statistically oriented thinking in football, which is also of interest to fans. Digitalisation is also closely linked to sports consumption, which is why we have seen significant changes in this area in recent years. The pandemic has further amplified the speed of digital transformation in the sports industry. One of the most important contents for sports organizations and their fans is the in-depth sports statistics and analysis that enhances the consumer experience. In our study, we examined the most common performance indicator in football, passing. Our goal was to examine the position-specific pass characteristics in detail, therefore we also examined different pass properties in our research. As a model for our analysis, I chose the premier league, which has the highest UEFA coefficient. The three rounds (rounds 30-32) of the championship season 2019/2020 have been recorded and analyzed in terms of passes. there was a significant difference between the average number of passes per game between defensive and offensive players (t=7,988, p<0.05). There is also a gradual decrease in the number of passes attempted per match and the accuracy of the pass in the examination of the middle positions when examining the positions in the depth of the pitch. For both pass accuracy and average pass count, the decreasing ranking corresponds to the position of positions on the pitch (order: 1, central defender 2, defensive midfielder 3, inside midfielder 4, attacking midfielder 5, striker). In the value indicator of the position for passes, offensive positions performed more effectively than defensive positions. The extreme positions also stand out among the attacking positions, where in the case of the position value per pass number, 23.3% of the total test was completed and 14% of the amount of the established position value indicators was provided by these posts. Overall, our study points to post-specific pass characteristics and, knowing this, we can state that the comparison of players' passing performance is relevant if the players are in the same or related positions.

    Based on the OCAI model, our study analyses and compares two things (1) the corporate culture of the University of Debrecen Faculty of Engineering as it is perceived by its engineering management students; and (2) the culture they think would be ideal. According to the respondents the existing culture is closer to the clan type and further from the market type compared to the average. Their ideal culture is closer to the clan, adhocracy and further from the market (compared to the average). The perceived current and the ideal culture are significantly different only in the adhocracy type. From the 20 items of the OCAI questionnaire 7 were significantly different from the average in the case of the perceived culture and 13 in the case of the ideal culture. Differences between ideal and present cultures are statistically supported only in the following dimensions: dominant characteristics (clan is currently stronger, adhocracy is weaker), corporate leadership (market is currently stronger), strategic emphasis (hierarchy is currently stronger).

    To achieve the strategic objectives of the management of a company, has to monitor and coordinate continuously the tasks of the employees, they have to do to reach the targets. In this action, sometimes the management of the company has to make corrections in the work and motivations of the employees. This article presents a case study carried out on a medium-sized companies working on the light industry field. It presents a new motivation system for the employees to increase up those products, for those who are at the bottom of the producing rankings of the company, moreover to develop their performance to reach the average level. Here has to be mentioned that, the employees at the bottom of the performance rankings producing under the average levelobligates totally the same amount of circulating and standing capita of the company, lead to the intervention of the management. The norm based requirements within the framework of the production system were completed to provide the more efficient working of the employees, besides strengthen their skills and their loyalties to their colleagues. As a result of the innovation of the performance management the product of the employees standing at he bottom of the rankings increased up considerably. It has manifested formerly in the decrease of the pointing error fixed to the personal monthly norm, moreover it showed the catching up of the employees standing at the bottom of the ranking to the middle. The case that the employees at the bottom get closer to the others in the middle of the ranking helped to contribute to achieve the strategic objectives of the management through reducing the average cost of the producing, since increasing the budget of the producing activities.

    In this study, we have dealt with the calculation methods of the eigenfrequencies associated with the bending vibrations of rectangular-shaped beams clamped at both ends. Said eigenfrequencies were determined analytically in the single-degree of freedom model of the beam and the case of the three-dimensional solid and three-dimensional rod models by finite element modal vibration analysis. We presented the calculation method of the characteristics of the analytical model and then calculated the eigenfrequency for a concrete example. We have described the concept of modal characteristics, and in the following, we have determined its natural frequency based on the solid-beam and rod models of the former beam. We calculated and compared the solutions belonging to the models recorded in different ways in 11 additional cases of the presented methods.

  • How Does Public Debt Change when the Next Crisis Comes - and It Will Come!/the Expected Evolution of Greece's State Debt in the Next Crisis Period/

    It has recently been announced that Greece may withdraw from the Euro-Zone permanent rescue fund's aid program because it has successfully met the conditions imposed on it. Creditors and credit qualifiers also agreed that the Greek economy was on a good growth path. That is why there is a chance that by 2030 the current sovereign gross debt of 182.7 per cent of GDP will fall to 123.3 per cent. The author finds this statement unfoundedly optimistic. He argues that the Greek debt ratio – despite the current optimum economic fundamentals – does not seem to be sustainable. He sees greater probability that in the near future it will again be necessary to release some of the Greek debt. Debt reduction will also mean a new orderly state bankruptcy. The study seeks to highlight how vulnerable and risked the sustainability of current Greek debt financing. Using a macroeconomic model, it shows and justifies how the Greek sovereign debt changes in the case of a crisis that is only half the extent of the previous subprime crisis. If this happens, by 2023, the state debt will rise to more than double the national product, and by 2030 only to the present, otherwise critical, level. It follows that the high risk of financing Greek state debt remains unchanged.

    Challenges of the 21st century require answers from higher education as well. In Europe, most of the entrepreneurship programmes on the higher education institutions are less than ten years old. Whilst business studies may battle for academic legitimacy, it has a clear advantage when it comes to graduate employability. The aim of this paper is to give answer to the following questions: why entrepreneurship education is important, what are the methods which are already used and what are the results of them. The answers to the questions are based on literature reviews, a case study and in-depth interviews with alumni carried out at the University of Debrecen, where since 2010 Team Academy Debrecen, a new education model from Finland is implemented. Tiimiakatemia education is an innovative Finnish model founded in 1993 by Johannes Partanen that develops team entrepreneurs. Based on the results some of the important elements of entrepreneurship teachability are: learning by doing, passion, learning in teams, coaching and mentoring.

  • Testing the Sametest-effect in a BSc-level Business Communication Course Examination

    Using secondary data, we empirically examine two biasing effects that may arise in the written evaluation of large groups of students. Suppose the students take the examination in consecutive groups, and we wish to avoid the distortion caused by tests of different difficulty. In that case, we can decide to use the same examination questions. However, the danger of the "same test effect" arises, according to which the group writing later can perform better if it receives information from the examinees in the previous round. Using the same examination tests cannot be recommended if that effect is significant. Another related potential phenomenon is the "revealed sameness effect". Accordingly, if the examinees are aware of the repetition of the questions, it significantly increases the scores of the following group. We tested these phenomena using the data of a three-round written examination. A previously published analysis of a larger sample found that the "same test effect" can be expected if the students decide in which round they take the examination. Since it was possible to freely register for the examination rounds for the assessment analyzed in this study, we assume that the "same test effect" will be significant. Based on the literature, we also expected that the "revealed sameness effect" would occur in the third round. The performed linear regression analysis (N=77) only found some weak evidence for the 'revealed sameness effect' but not for the 'same test effect'.

    Diagnostics of batteries using advanced methods have gained remarkable roles in the past few years. This study focuses on the type of measurements, tests and methods to reveal and classify them. During manufacturing and operation several faults could emerge in batteries including non-optimal operation conditions, operators without experience, and finally, random changes in batteries under physical and nonphysical conditions. Improper handling of batteries and battery cells man cause operation failures or, in the worst case, accidents. To reveal these problems several methods are applied in industry and in scientific laboratories. For a comprehensive analysis of battery management, artificial intelligence and Industry 4.0 methods can be used very effectively. Big Data analysis in its standard form is not a new achievement, but other mathematical tools could be applied to control monitoring such as Fuzzy Logic or Support Vector Machine (SVM). They are efficient tools to analyse the deviation of batteries condition because it can detect sudden changes, parameter deviations and anomalies, and the user’s behaviour and habits. This article gives a description about the most important battery testing methods and the connection between Big Data and Operation Management with Artificial Intelligent (AI) methods.

    In market economies, the subject of scientific research is the extent to which the state can contribute to the sustainability of development. However, the question is to know where the boundaries of the market and the role of the state lie. The study briefly introduces different views of the state's economic role and how states have changed the proportion of their entrepreneurial assets. Among these, it highlights privatization, which is one of the significant segments of today's economic policy practice at both micro and macroeconomic levels. It then describes Brazil's economic circumstances that led to the formulation of a proper size privatization program. Finally, the socio-economic factors that, according to the author, make the realization of Brazilian privatization plans uncertain presented.

    Our study analyses the connection between perceived and ideal organizational cultures and academic results. A modified, self-managed OCAI questionnaire was used to measure perceived and ideal organizational cultures among engineering management students of the University of Debrecen Faculty of Engineering (N = 114). Our results reveal weak positive linear correlations between academic performance and perceived or ideal level of clan culture. In case of other culture types we did not find any consistent relationship. Based on our results students who consider clan culture ideal can expect better results than those who prefer other types. Among students who visit at least 61% of the classes those who reported fitting (or better fitting) perceived and ideal cultures tend to perform better in their studies.

    In this study we examined the digital competences by the EU Member States between 2015 and 2017 based on data of OECD and EuroStat. We wanted to know, are there any relationship between the unemployment and the level of digital competences. We realised that, in these countries where the percentage of individuals with basic digital skills is higher, there the harmonized unemployment rate is lower, than in those states where the individuals have above-average digital skills. In the case of lower educated states (where the citizens do not have a general digital knowledge), the unemployment rate is higher. We researched the openness of companies towards individuals with different levels of digital knowledge. In these countries, where the more educated people live there provide the comapnies more chance to take part further trainings, than in the less educated countires. We found a moderately strong negative correlation between the group of individuals who have low overall digital skills and in-work trainings. It means, if a country has individuals with a few digital competences, there the organisations will not offer trainings them. According to the available data we could divide the EU Member States in three clusters. These groups are underdeveloped, developing, developed countries. The biggest difference is between these groups in the quantity of skilled people, however the distribution of individuals in the developed group also shows interesting features. We realised in these countries the so-called „reverse competence pyramid”. It means, as the level of skill grows, the number of individuals, who own it, grows as well. As a continuation of the research, it would be worth examining the countries regionally, so it would be clear where are, the "digital kingdoms" can be found. On the one hand this could help the state in the allocation of digital education, on the other hand, it would also improve the position of companies. They could create regional centers in less developed countries, thus outsourcing expensive high added value work.

    The main target of companies is to earn money and achieve profit. In order to fulfil these needs, companies have to reduce their costs. Cost reduction is often associated with bad quality products, but it could be done in a different way. Sometimes it is enough to examine only their own processes and then benefit from the process optimization, process improvement or process scheduling. In this article a case study is presented, in which the differences in a production scheduling are evaluated with the application of Monte-Carlo simulation and descriptive statistics. At the end of the paper the most efficient material sequence is selected at the manufacturing company by using weighted sum model

    Continuous learning is part of everyday life. It may be formal, non-formal or informal nature. The formal learning that takes place at school, is the basis of expertise. Why someone sitting to school? There can be given many answers to this question. The motivation for learning develops due to both internal and external factors. And even age groups and training as equally different. With regard to adult learning motivation was examining several surveys. The study is a summary of the test results. There was three target group: high school seniors, correspondence master's students and participants accredited training. The surveys set out to discover Why learn the various forms of training. The questions in each test were different but comparable. For participants accredited training habitual motivation is crucial. Their joy and pride of the family is less important to them. , Correspondence master's students were considered the most important things income, learning, and knowledge. Although the perception of other age groups, both the habitual and the actual motivation appears in every group. While high school students based on the results we can say that the more motivation to achieve a goal, such as employment, income acquire. so prominent the habitual motivation. In their case it emphasized that a distinction was made between friendship and relationship network. Namely, the friendships are not identified with the mere knowledge that may be necessary in order to achieve future goals.

    Nowadays, in the world's energy production structure, fossil fuels dominate and at the same time cause a number of environmental problems. Comparing the use of conventional fossil fuels with geothermal energy, this kind of energy production is extremely beneficial, as there are no pollutants and a renewable energy source. Moreover, if we want to compare geothermal energy with other renewable energy sources (such as wind energy, solar energy, etc.), much of the benefits can also be attributed to geothermal energy becouse it is a stable energy source and the area requirement is low. Due to these extremely favorable properties, the study of the applicability of geothermal energy is gaining ground in renewable energy sources. In addition, it is well known that there are approximately 20 to 30 million abandoned oil wells in the world, plus sealed wells for other purposes, and the final number may be much larger. In the case of abandoned oil wells, the escaping residual oil may be a problem, which can lead to significant environmental problems. Taking these factors into account, research on the recyclability of abandoned wells for geothermal purposes becomes a target for more and more research topics around the world. It is interesting to note that a significant part of the publications are concerned with examining the technological potential of energy utilization, studying heat transport processes, and generating general, energetic or economical evaluations. A publication of a kind that would have evaluated the safety of recyclable abandoned wells in publishing databases was limited. It is therefore an important question that the abandoned wells, from the point of view of human security and environmental protection. How can they be reactive, how can the new technological elements be built up and how much human security factors of the newly created system are affected by the existing elements?

    Workplace mobbing (psychological harassment) can be a great challenge for the management of any organization. Although the phenomenon has been discovered for quite some time, there is still no unequivocal definition, and therefore preventive and managerial actions are rudimentary. It is clear that mobbing affects not only on the individual employee, but the whole organization. The reduction of commitment of people working in this environment (and not only those directly affected by it) may have a detrimental effect on the performance of the organization. I will present a legal case study to highlight some of the general and procedural shortcomings of mobbing at the workplace.
