Sports Civic Organizations-Conceptualization Issues and Trials
127-135Views:154Lately published statistics of the Hungarian Central Statistical Office reveal such a phenomenon that in some years (between 2011 and 2015), that the number of sport related classic civic organizations has increased in the narrowing non-profit sphere. Inside, the role of sport has been intensified primarily among the sports associations, and not among the foundations. Considering the Central Statistical Office methodology, the questions arises and serves an issue that how can we conceptualize a sport civic organization. Regarding the same topic, we may face diverse databases, and it also seems that different conceptualization approaches exist, we do not have uniform regulation, and current data also raise further questions. Through a “from general to specific approach” we aim to reveal that in what way a civic organization can be considered to be a sports related civic organizations and also try to highlight the consequences of this plural approach.

Research of Healthy Behavior at Faculty of Economic Sciences' sport sciences' students at the University of Debrecen
165-180Views:486Nowadays the healthy lifestyle is getting more and more attention, thanks to emerging health trends. The review of the literature summarizes the latest results of research on two aspects of healthy behavior. In our primary research, we measured the sporting and dietry habits of sport sciences’ students at University of Debrecen. In the case of sporting habits, we asked the students about the frequency and motivation of sports. In the other hand we asked them about their dietary habits about the frequency and amount of vegetable, fruit and fluid consumption. After the evaluation of survey we can say that the 70% of respondents are satisfied with their physical condition. We can tell about the frequency of vegetable and fruit consumption is that the 15-20% of students eat vegetables and / or fruits daily. However, it can be said about the fluid intake of students that seventysix percent of them are consuming fluid daily.

Quality Development of a New Type Pharmaceutical Formulation
112-127Views:230The aims of companies to understand internal and external customer demands in order to improve their existing products and develop new ones. Product development aims at understanding customer demands that may influence the production of the product to be manufactured. As a first step in the process, the customer voice method was used to define demands with measurable parameters. A questionnaire survey was used to prioritise them, which were then compared and ranked using a preference matrix. Within the QFD method, technical parameters influencing the satisfaction of customer demands were determined. A correlation matrix was established and the relationship between the technical parameters was investigated. A competition analysis of technical parameters and customer demands was carried out. From the absolute and relative weights, it is easy to establish the order of the technical parameters, so that the most important parameter in terms of meeting the defined customer demands is the determination of the ratio of raw materials, and important parameters are chemical stability, pharmaceutical formulation and particle size.

The Relationship Between Sports Civic Organizations and Human Resources
146-154Views:225Every spring the Hungarian Central Statistical Office records through its ELEKTRA database system the human and economic related operation data of the past year of civic organizations. This data source is usually considered as a standard at the evaluation of the domestic civic sphere. Still, the available handout titled “Most important features of the non-profit sector”, applying mainly descriptive statistics only provides a brief picture of specifications of the sector. Parallel with it, its background database is available yearly, which provides a unique possibility for a researcher to perform secondary analysis aiming to reveal deeper relationship. The objective of our study is purely to reveal a minor part of this considerable field, the relationship between subsidies and human resources mainly due to the fact, that human resource in this sector is composed of employees and volunteers, and it is questionable whether subsidies have an impact on employment. Results revealed that there is a relationship between human resources and subsidies, where mainly private nature subsidies have a strong impact equally on voluntariness and work related employment

Sport Consumption, Fan Engagement, Sport Statistics – Post-specific Passing Characteristics in Football
Views:657Digitalization 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.

Sportcivil szervezetek – számok a támogatások növekedése mögött
126-134Views:170A KSH adatgyűjtési tevékenységének köszönhetően a nonprofit szervezetekre vonatkozó átfogó adatok mind adatbázis, mind tájékoztató formájában elérhetőek. A gazdasági adatok között feltűnik az az évről-évre hasonló nagyságú, domináns támogatási részesedés. Különös tekintettel a klasszikus civil szervezetekre ez egyértelműen jelzi azt, hogy a szféra támogatáskitett és támogatásfüggő. Ezek a szervezetek ugyanis kimondottan alkalmasak támogatások fogadására. Tanulmányunkban szeretnénk másodelemzés révén rávilágítani arra, hogy a sporttal foglalkozó civil szervezetek/sportcivil szervezetek száma milyen összefüggésben van a támogatásokkal, különös tekintettel két specifikus támogatási formára, a NEA-ra és a TAO-ra vonatkozóan. Az eredmények arra utalnak, hogy van összefüggés a támogatások összegének növekedése és a sportcivil szervezetek számbeli növekedése között, és ez kifejezetten igaz az egyik legrégebbi és legújabb támogatási forma esetében is.

Climate-Neutral Energy Production - Prospects in Hungary in 2024
53-60Views:79In order to protect our planet's climate, it is important to reduce humanity's carbon dioxide emissions significantly. The energy sector is one of the most polluting industries, but the rapid spread of renewable energy sources over the past 20 years can significantly contribute to the reduction of carbon dioxide emissions. The study examined which energy sources are used to produce electricity in Hungary, and how the proportion of renewable energy has developed in recent years compared to more polluting energy production methods. There is a strong negative exponential relationship between the share of renewable energy and the carbon dioxide emissions of the energy sector, based on which the carbon dioxide emissions of the energy sector can be significantly reduced by increasing the share of renewable energy. A forecast was made for the renewable share based on past data and the revised state of the National Energy and Climate Plan in 2023, and a linear forecast was made for the energy sector's emissions. There is a strong exponential relationship between the data series. Both models examined in the study had strong explanatory power, but neither model supports the possibility of climate-neutral energy production by 2030.

Evaluation Opportunities tor Recreational Sport Services – Adapted to Higher Education Environment
150-164Views:236In our study, we analyse various researches dealing with quality aspects of sport services, and different quality models related to the interpretation of quality. The results which were obtained in the framework of primary research activity present the opinions of students from five different research universities. Sport services’ operation and sustainability are determined by market regulations, as parts of the service industry. Considering that the university leisure sports services take place in a competitive environment, the universities often have to compete with external sports service providers for achieving confidence of the young generations. For the qualitative tests, we used the QSport-14 measurement scale, which is generally applied by sports centres. This scale investigates the sports services according to three different aspects: (1) instructors, (2) infrastructural facilities and equipment and (3) offered sport programs. We have adapted the measurement scale to the university environment because of the differences and special characteristics of external sports service providers and university sports services. In addition, we analysed the factors influencing recreational sports, and we also examined that what changes would be needed in order to improve the quality of recreational sport activities in higher education.

Sport Civic Society – Approaches and Facts
158-166Views:249After the change of regime in Hungary in 1989, the domestic civic sphere started to improve, and after numerous change in the legal regulation, currently the Act on Civic Organizations (Act 174/2011.) rules the operation of the sector before all, supplemented by additional legal background. The vital component of the new regulation is possibility of the appearance of the novel organizational form, the civic society, which is quite odd even considering the past and even on international level. The database enabling the statistical overview of the domestic nonprofits publish the end of 2019 provides no information on the data and operational features for this organizational form, which provides a thorough reason for the researcher to be interested in the topic and the organizations. Through the possible secondary data, a primary database of a lately done sports civic organization related research includes such basic data (even its sample height is small), which may be considered as a starting point at the examination of the specifications of the sports related civic societies.

Floorball position and passive sports consumption in the light of a study
142-157Views:235Research 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.

Maintenance Strategies and Life Cycle Costs of Renewable Energy Systems
106-116Views:141Life cycle costs are important factors in decisions on renewable energy investments. Since maintenance costs generally constitute a high portion of the life cycle costs, the maintenance strategy applied in a project can affect the bottom line significantly. The effective maintenance tools used in the production industry (e.g., diagnostics, condition monitoring, data management, integrated information systems, machine learning, and automated decision making) can be involved in planning and maintenance of renewable energy systems to gain the benefits of these approaches. In this paper the effects of maintenance strategies on life cycle costs are investigated and the benefits of up-to-date condition monitoring techniques are presented through case studies.

Changes in the financing of domestic research and development
153-161Views:178Nowadays, the fourth industrial revolution is taking place at an incredible speed, with innovation at its heart. Of this, R & D funding is of paramount importance, which is directly or indirectly one of the most important tools for increasing corporate competitiveness. The study examines trends in domestic R & D expenditures over the past one and a half decades. It focuses on the extent to which the financial crisis has affected the amount of funding resources and their structure. From an international comparison, Hungary and the European Union spend much less on research and development than those in the global competition. The impact of the crisis is reflected in the decline in the growth dynamics of R & D expenditures, but it has not been solved solely as a result of the crisis. Changes in the domestic structure of expenditures in recent years are encouraging and are in sync with the change in attitude that is considered desirable in R & D funding. If we examine the domestic statistical data more thoroughly, we can no longer be very satisfied. However, from trends in data from recent years, it becomes apparent that neither Hungary nor the European Union will achieve the 1.8 and 3.0 per cent of GDP R & D spending by 2020.

Evaluation of a Trainee Program’s Selection and Induction
502-511Views:603The research based on the trainee program of a large Hungarian company. The company recommends the program to entrants or those who have 1-1,5 years of work experience. The main objective is the evaluation of the effectiveness of the program through some of the HR functions. This study contains the process of the selection and the evaluation of getting into the program. What makes the program special, is the appearance of the technical mentor. According to the hypothesis, the mentor’s assistance reduces the uncertainty when the trainee inducted into the organization. The occasions of the beginner education, the conversations and feedbacks during the induction adds more efficiency to the success of the program. The searched data in literature features HR functions and mentoring. To learn about the program, a case study was made beforehand, and then the questionnaire was edited for the trainees at the company. In the course of the research, an interview was done with the technical mentor. The interview was based on the questionnaire. In point of the results, recommendations were defined connected to the assumed shortages of the program, also to increase the efficiency of the selection and induction. In conclusion, the maintenance of the trainee program is equally beneficial for the trainees and for the company as well.

Servant, Ethical and Authentic Comparative Analysis of Leadership Styles in the Light of the Challenges of the BANI World
43-52Views:90In 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.

Business Students’ Attitude to Social Responsibility
1-10Views:277The companies’ most important goal is the satisfaction of consumers’ needs and the profitmaking. But nowadays the companies have to deal with the activity of corporate social responsibility, too. Therefore it can be interesting to research about the next questions: can ethics be taught? Do we have to teach ethics in the schools and especially in the business schools? What are the students’ attitudes toward the social responsibility? Are students sensitive and open-minded connection with this issues? The aims of the study were to examine responsible management attitudes among business students at the University of Debrecen (Faculty of Economics and Business). We draw their CSR pyramid (based on Carroll model) and present their opinion in reference to business education’s role in social issues.

The Relationship Between Renewable Energy Consumption, Net Energy Import, Greenhouse Gas Emission and Human Cap
58-71Views:169The measures to improve energy efficiency and increase of renewable energy production and consumption should be encouraged in the interest of sustainable development. Many factors can influence the use of renewable energy such as the level of economic development of an economy, nationals’ and the main economic actors’ environmental awareness, energy import dependency, ratio of the urban population, and government subsidization intensity among the others. The main purpose of this study is to examine the relationship between the share of renewable energy in the total energy consumption and net energy import as a percentage of energy use less production, greenhouse gas emission per capita and human capital using by OECD countries data from 1990 to 2014. The results indicate that there is a negative relationship between net energy import and renewable energy consumption, and also negative relationship can be shown between the amount of greenhouse gas emission per capita and renewable energy consumption. However, we identified a positive relationship between human capital and renewable energy consumption for energy importer countries above a certain level of human capital.

Markmyprofessor: the More the Better?
232-243Views:1240Student 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.
