    In the globalized and accelerated world of our time, challenges can only be met by companies that possess the necessary information and are able to convert it rapidly into organizational knowledge. Annual accounting statements are an important source of information within business relations among companies. 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. Decision-making based on inadequate knowledge further increases economic risks that are already high. 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 information-technology services (Hungarian NACE No. 62) 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.

    Contribution of the sports sector to GDP in the EU Member States is close to 5%, while in Hungary it is approximately 1-1.5%. This ratio is likely to increase, for which various subsidies of corporate tax provide a good basis. The information mentioned above confirms that the economic analysis of companies engaged in sports activities is an interesting and necessary field of research. 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. The sports activity companies are analysed using various packages of the R statistical system. By means of text mining, we analyse the extent to which the notes on the accounts provide the necessary information that would be indispensable for the proper interpretation of the balance sheet and the profit and loss account.

    The aircrafts are responsible for emitting several types of pollutants, especially the pollutants in the form of NOX, CO2, CO, UHC, SOX and Particulate Matter PM (smoke/soot). The impact of aviation emissions on the global is well known, where these emissions modify the chemical and microphysical properties of the atmosphere resulting in changes of earth’s climate system, which can ultimate in critical changes in our planet fragile ecosystem, also the pollutants produced by aircraft engines cause many health problems. This is why the International Civil Aviation Organisation (ICAO) is seriously seeking to control the emission levels by issuing new standards during the successive meetings of the Committee on Aviation Environmental Protection CAEP (CAEP/01 in 1986, CAEP/2, CAEP/4, CAEP/6, CAEP/8, etc). The new regulations include more stringent standards aimed to reduce emission levels, this led to increased interest in low emission technologies. In this paper, a comprehensive review of low emissions combustion technologies for modern aero gas turbines is represented. The current low emission technologies include the high Technologies Readiness Level (TRL) including RQL, TAPS, DAC and LDI. Also, there are advanced technologies at lower TRL including LPP, ASC and VGC.

    The spread of the gameable personal computers and game consoles resulted in the diversification of the video game genre, and from the 7th generation of the gaming consoles, the experience support of the games became largely enhanced. These games are now consumable owing to their resolution, the content, the plots are so fascinating so that they tie the gamer to the seat. Gamers seek experiences in the games. Still, such a special genre called roguelike was established, which is characterized by the constant termination of this world of experience in such a way that the gamer, as a results of the high level of difficulty, is obliged to start the game again and again. These new genre games are now leading titles of the new generation consoles, such as Demon’s Souls or the Returnal, gaining huge role in the introduction and sale of the new gaming console PS5. This study aims to reveal specifications of this genre, moreover, aims to describe through empirical research how gamers relate to it, and whether features of these games contribute to the devotion to them or lead to the disappointment from this world of experience.

    When we discuss the topic of civic organizations, especially sports profile civic organizations we need to note and comment that issue how these organizational forms are able and capable to accept subsidies. The related data of the Central Statistical Office (KSH) highlight the phenomenon that incomes of the classic civic organizations are mainly composed of state or private source donations. Although there is a really and pretty predictable subsidy system in the field of civic sphere currently, from one hand the distribution of the single subsidy forms considerably vary, on the other hand it result in the considerable amount of available financial resources. The fact whether subsidy forms and subsidy incomes have relationship with the addition alvariables of the organizational operation, such as subsidies provided, employment relationship, and expenditures may acquire special attention at the management of organizational operation together with the planned strategic interventions in the field of the civic sphere.

    In 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.

    Over the last decade, the public has been paying increasing attention to reducing greenhouse gas and acid rain emissions and reducing particulate matter, which is extremely harmful to health and the environment. To improve air quality, the European Commission has achieved a range of measures to reduce air pollutant emissions in the transport, heat and electricity, industrial and agricultural sectors. In Hungary, the amount of gas and solid air pollutants from solid fuel combustion used by the public during the heating season represents a significant percentage of the total amount present in the atmosphere. In 2016, taking into the total emission, the 29% of CO2 emissions; 85% of CO emissions; 75% of the particulate matter emissions and 21% of the NOx emissions were derived from households. It follows that the improvement of air quality can also be achieved by controlling the emissions of solid fuel combustion plants. During our research we aimed to optimize the operation of a newly purchased TOTYA S18 boiler and a pilot pellet boiler. Operating the boilers in the correct mode minimizes air pollutant emissions, and the greater part of the heat generated is actually turns to heating the home, as with poor settings, a lot of heat leaves through the chimney. The data obtained during the tests can also be used to determine whether the boilers comply with the emission values set out in Commission Regulation (EU) 2015/1185.

    Equestrian services appear in recreation, sports and tourism as well. The favorable natural and cultural values of Hungary and the image of the equestrian nation based on the traditions of the horse provide a favorable background for the development of supply elements. The lowland character and horse culture of the Northern Great Plain region, and the continuous development of horseback riding services here, reinforces the equestrian supply element in the field of sport and leisure. Our in - depth interviews were conducted among service providers with a “horseshoe rating” (N = 11) operating in the Northern Great Plain Region. The results show that all service providers consider and plan the development of equine, infrastructure and human resources, although the source of its financing is different (from state, other successful businesses, realized business results of equestrian enterprises). Equestrian service providers with no horseshoe rating have identified the improvement of quality, the 3, 4, and 5 horseshoe qualified service providers for the expansion of the complex program offering and product diversification.

    Based on the model of the Deloitte Football Money League we recreated the „Hungarian Football Money League”, which gathers and analyses the most economically powerful Hungarian football enterprises. The model gave us an oppurtunity to analyse and compare the industry to the international level. With the hungarian professional football-enterprises we assume, the most economically powerful teams play in the NB. I. (National Championship). Because of this reason we only analysed NB 1. club teams. From the 12 participating team we selected only those 9 who stayed in the League for three consecutive years. The implications from this study is that the hungarian club teams stays well below the international level, altought top level enterprises' joint economical impact is indeed significant in the hungarian sportsector.

    As 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.

    My 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.

    Faster 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.

    Strong links between universities, and companies can play crucial role in promoting taking into practice of ideas that drive the knowledge society, and in raising competitiveness and living standards. In academic terms of IP management, all activities aimed at sharing knowledge generated in research institutions as a knowledge transfer including scientific publishing, conference presentations, collaborative research with external partners, and contract-based clustering activities, such as licensing and spin-offs. In a narrower sense, the IP management means technology transfer is aimed at placing a given technology on the market, and includes any process by which the recovery partner becomes able to produce new products or services. IP with traditional university mission, values, and activities primarily focusing an active university role in entrepreneurship and contracts with private sector for IP commercialization. This paper gives a comprehensive overview about IP management in universities of the European Higher Education System including the following aspects: partnerships (licensing, industry collaborators); IP invention (disclosures, patenting); proof of concept research bridging the gap between lab discoveries and market application (highly innovative R&D to solve practical problems and commercialization research aiming patented technologies towards business exploitations) and commercialization (start-up incubators and strengthening the entrepreneurial attitudes and competencies). The methodology based on secondary research analysing EU, OECD, on-line literature sources and relevant, up-to date statistical data as well. The conclusions and recommendations based on this „desk research” work reflects the authors.

    Control, az a managerial function cannot be considered as one of the most frequently preferred examinational topics, and it is also valid for the matter of civic organization. Nevertheless, we must not forget about the increasing number and intensive non-profit sphere after the change of the regime, where the civic sphere inside has become determinant. In 2017, 15,2% of the 61 151 nonprofit organizations had a sport profile, and this ratio is higher, 16,2% regarding the 53 613 classic civic organizations (including only associations and foundations).  The specialty of these organizations is the strong relationship with subsidies, and it seems that it has turned into subsidy dependence by now (2/3 of the incomes are subsidies), as a conclusion from the data of the Hungarian Statistical Office. This topic may also become sensible in a way, when an organization cannot account the received subsidies or cannot meet expectations of the judicial expectations, which all raises managerial control related concerns. It also highlights the relationship between civic organizations and control. In this study, we aim to cover some relevant specifications of the topic through the control, as a managerial function, and based on the results we may conclude that a higher ratio of organizations cannot really perform by the expectations.

    The 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.
