Survey of population knowledge on the technical characteristics and physiological effects of light pollution in two settlements
155-161Views:180One of the newest environmental challenges in our industrialized world is light pollution. It means that we emit more light than necessary, and this is often done at wavelengths that are both disturbing and even harmful to human health. The Dark Sky Parks, where over a large area there are no artificial light sources that burden the environment. One of these parks is located in BAZ County, near Répáshuta, and is under continuous development. Our study reports on a questionnaire survey conducted in Répáshuta, which is informed about light pollution, and in Cserépváralja settlements close to it, but without direct knowledge of the problem. The population of both villages is around 400. With a direct on-site survey, we asked 21-21 questions to 30-30 person and received answers in all cases, of course, taking full account of the anonymity of the respondents. Recruitment took place in March and April 2019.

Strategic Role of HR in Hungary and Slovakia, Based on the International Cranet Research (2015-2016)
478-489Views:328Western-European management trends have been spread including modern approaches to human resource management over the past decades in the countries of Central and Eastern Europe. The point of the new HR conception is the strategic partner role, which is underpinned by the appreciation of human resources. There was a rapid change in the management methods of the organizations due to the socio-economic changes in the examined countries. However, in many places the personnel departments were simply renamed, and their HR staff are still concentrating on their traditional activities. These activities are important and should be fulfilled today as well, but to play an influential role in the design and maintenance of organizational competitiveness HR should have a new, strategic attitude. The study examines HR's strategic role based on the empirical international Cranet research in Hungary and in Slovakia.

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.

„Return to the Countryside” – a Qualitative Approach of Students’ Opinions About Rural Life
204-216Views:238Nowadays, the research of rural areas’ specific features is one of the most interesting part of sociology. Within these studies the rural areas ability for survival and to retain forms an important basis. A pillar of these, that the youth from rural areas become sufficiently motivated to stay at or to return to their homeland and be able to redound development. We were looking for answers, that how university students, who participated in our current research are thinking about the hungarian countryside, in their opinion what are it’s advantages and disadvantages and it’s possible potentials. In addition, we examined those factors, which are contributing to that respondents who are studying in large cities want to stay there, but at the same time we wanted to explore the opposite factors, those that make tudents to return to the countryside. Last, but not least we investigated a very interesting topic, the relations between the respondents and the rural elite.

Extreme Sports Consumption Implications from a Re-search
135-145Views:802Nowadays, 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).

Wearable technology usage among students of the University of Debrecen
33-47Views:150The lack of physical activity and the growing prevalence of a sedentary lifestyle are urgent public health problem worldwide. The problem is also typical of the young population, especially university students, who spend most of the day in a sitting position. Technological development is one of the catalysts for the rise of a sedentary lifestyle, nevertheless, thanks to this, many devices have appeared on the market that can be used to encourage physical activity. The widespread of wearable activity tracker devices – wristwatches, wristbands – among the population shows a constantly increasing trend, with a parallel increase in the amount of data collected about ourselves (step count, calories burned, heart rate). The main goal of the present study derives from the recognition of the gap in this field in the domestic sports science literature therefore our focus is on modern information technology tools in the dimension of physical activity. The aim of this study is to assess the attitudes of the university student population towards activity-tracking devices. We conducted a cross-sectional online quantitative survey (questionnaire) among DE GTK students. 340 people filled out the questionnaire correctly. In addition to descriptive statistics, parametric and non-parametric tests (Pearson's chi-square test, Fisher's exact test, t-test, Mann-Whitney test) were used to examine the relationships. The results of the statistical tests were considered significant if p<0.05. We performed the distribution of the variables using the Kolgomorov-Smirnov test. The majority of respondents (55%) have already tried some kind of wearable device that measures physical activity. Every third student (34%) are currently using their device. Those who have not tried these devices so far indicated the price as the primary deterrent. 32% of the students plan to invest in such a device in the future. 39% of device users use an activity tracker bracelet, while 61% use or used a smartwatch. In terms of sex, we did not find any differences in asset ownership. The primary goal of the students (66.8%) was to track their physical activity. The most frequently used function was tracking the number of steps, indicated by 81% of the respondents, followed by heart rate measurement (67%). Most of them (69%) set some kind of goal regarding their number of steps. According to every third student, they moved more as a result of the device and managed to maintain the increased level of physical activity. 44% of the students claimed that their physical activity did not change despite using the device. Students tend to disagree with the positive statements related to the devices in connection with a healthy lifestyle. Although the present study suggests that wearable devices have an impact on students and they track their measured data, it is questionable whether the devices themselves are enough of an incentive for students to develop a healthier lifestyle.

Application of Team Coaching Tools for University Education – Case Study
445-456Views:497In 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.

An Analysis of the Leisure Preference System of Students with Disabilities in the Light of a Study
98-115Views:706With the increase in the number of disabled people and people with disabilities, research on the target group of people with disabilities has gained momentum in recent decades. Research is very diverse, looking at the labor market situation of people with disabilities, their leisure-time habits, or the factors that support and inhibit their sport.
In our questionnaire research, the leisure and sporting habits of children with disabilities aged 8-18 are described and analyzed (N = 639). Data were processed with spss software, where basic statistics and contextual analysis were performed. The results confirm that passive activities (TV, listening to music) dominate the leisure activities of children with disabilities. Sports consumption (active and passive) was more prevalent among male respondents and less prominent among girls. In the motivation of sports, besides improving the state of health, entertainment and company appeared.

Examination of the Informative Part of the Notes to the Financial Statement Amongst Hungarian Companies Engaged in Sports Activities
108-116Views:203Currently, the role of sports has intensified and changed; by now, it has become a separate area of interest from an originally civil, exercise-based, private leisure activity. In the case of sports-related economic research, both macro- and microeconomic research can be mentioned. Its economic significance, its contribution to employment, national economic income, and consumer spending is involved in macro-level research, while the examination of the functioning of sports services and organizations, and the characteristics of demand and supply are micro-level research activities. One of the reasons for the development of sports activities was the increase in their economic significance, which created a need for their economic analysis. The necessary information can only be obtained from the two fundamental parts of the annual statements (balance sheet and profit and loss account) if the notes on the account contains the information that contribute to the more comprehensive interpretation of the other parts of the annual statement. In our research, we examine whether the notes on the accounts of companies include the information, which could help obtain necessary financial knowledge concerning the partner companies. For the analyses, we used the notes on the accounts of companies, which have sports activity (Hungarian NACE No. 931) as their main line of business. By means of text mining, we analyse the extent to which the notes on the accounts are in conformity with the Accounting Act.

Study of the University Electronic Games E-sports League and Its E-sports Players
52-61Views:153E-sports are competitive video games coordinated by different leagues and organisations. E-sports players belong to teams or different managements, which are sponsored by various economic companies and establishment. In the beginning, only offline and then online competitions were organised, and nowadays an offline final takes place in sports halls at the end of an online qualification round. The primary objective of the present research is to study the e-athletes participating in the University Electronic Games (UEG) e-sports competition. In addition to the e-sports players, I consider it important to examine the tournament itself, how the players interviewed rate it and what motivated them to participate again. I conducted an online questionnaire survey among the participants of the three seasons of the UEG online tournament organised by the University of Debrecen. UEG is the largest university e-sport tournament in Hungary in terms of its number of participants, which is why it was selected for the study. The participants in the study are motivated to compete in order to achieve success and enjoy competing to win, for them e-sports is a self-fulfilment. They keep up to date with national e-sports news and competitions through social media and the university mailing system. In general, the participants rate the UEG e-sports championship highly. The organisers need to improve the organisation of the tournament and their preparedness to run a tournament of this size. Their strengths are their helpfulness and their accurate and precise information about the tournament.

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.

Opportunities to the urban air quality of characterization by the cost-effective electrochemical sensors
1-16Views:100The quality of urban is more and more affected by the accelerating urbanization. The efficiency of improving air quality can be increased by providing local information on each pollutant source. The aim of our activity is providing real-time high-spatial reasultion data about air quality of the Hungarian capital city, Budapest. In this paper, results of testing and calibration of different low-cost electrochemical sensors and localization of them are represented. The first selected sensor is suitable for detecting carbon dioxide (CO2), alcohols, benzene (C6H6), nitrogen oxides (NOx) and ammonia (NH3). The RingAir initiative also aims to involve the urban population in active environmental monitoring activities, therefore in the future we are planning to implement a more detailed and continuously updated monitoring system with the participation of a Budapest bicycle courier service and some of the city's population.

Global Inversion of Pressure Dependent Acoustic Velocity Data Based on a New Rock Physical Model
47-55Views:155In this paper with the further development of our previously published single exponential model, the new multiple exponential model describing the pressure dependence of acoustic longitudinal wave velocity is presented. Since with increasing pressure in the rock several relaxation mechanisms at the same time can cause the increasing propagation velocity, the new model can handle two or more physical mechanisms (e.g. the closure of pore volume or microcracks or friction on grain boundaries etc.). The previously applied linearized inversion procedure can trap in a local minimum, so during laboratory measured longitudinal velocity-pressure data processing a global optimization method was used to find the absolute minimum. Using the developed model equation as response equation in a Simulated Annealing algorithm the petrophysical parameters of the model can be determined. Inversion results proved that the calculated data using the new model and algorithm matched more accurate with measured data on a rock sample.

On Institutional Services from Foreign Students’ Perspective – What Makes a Higher Educational Institution Multicultural?
343-363Views:154Higher education is of the utmost importance in terms of the competitiveness of every nation, including the Hungarian economy, therefore it is considered determinant for the future to survey student mobility of foreign students pursuing their studies in Hungary. Demographic decline that is characteristic to Hungary, already makes its influence felt in higher education, therefore internationalisation of institutions is of essential importance in terms of their operation and sustainability. Currently, it cannot remain unmentioned that it is a question of vital importance for domestic higher education institutions – and this process might only be further strengthened in the future – how they are able to compensate declining domestic demand by making their workshops attractive to foreign students and researchers.

The Investigation Of Heat-Resistant PLA Produced By Additive Manufacturing Technology
24-29Views:189In recent years, additive manufacturing technologies have been increasingly used in both custom and small-series production. In such cases, the component must remain functional under realistic conditions.. This means that there must also has a load‑bearing capacity. In many cases, materials are already suitable for strength. However, in many cases (machine parts, outdoor use) the models need to operate reliably at higher temperatures. This seems to be solved by the most widespread additive manufacturing technology (FDM), with a new heat-resistant material, HT PLA. In many cases, the use of cooling is essential during manufacture, especially for parts with high overhangs where hardening of the material is required as soon as possible to achieve the correct surface quality. In this paper, we investigated the effect of cooling applied during manufacturing on the mechanical strength

Laboratory Testing of Rediffusion of Contaminants Using DKS-Permeameter
41-48Views:145Decades long hydrocarbon contaminations effecting heterogenous groundwater systems is a common problem both in Hungary and worldwide. Only the treatment of aquifer layers is possible with remediation technologies, so the contaminations remained in the aquitards are released back to the treated porous layer after the treatment due to the changes in concentration-gradient. This process is the so-called back-diffusion: as a result, the previously removed contaminations appear in the remediated layer again. In order to get better understanding of the rediffusion process and the influencing parameters series of measurements were carried out at the University of Miskolc Faculty of Earth Science and Engineering using a special laboratory device called DKS-permeameter. With the help of some small modifications it can be used for the modeling of backdiffusion. Artificially contaminated soil samples were built in the DKS-permeameter from which contaminanant release occured due to back-diffusion. The concentration values were determined with spectrophotometric measurements.

Experimental Study of Connections with Hardwood Studs
26-34Views:140Attitude change is needed in design of timber structures. Truss girder made of timber elements wi th small cross sections can be used on large spans. Constructing structures with the use of these prefabricated trusses reduces the need of in-site work, and makes the use of ti mber structures economic. Rods of truss can be connected with the use of hardwood stud. On this way all steel components can be eliminated from the truss, so it can be used in aggressive environment as well. Dowel type connection, with hard wood stud is the subject of the present research. Hardwood studs were investigated individually and also as the part of separated connections of the truss girder.
