    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.

    The innovation environment has changed a lot in the recent years, companies and their enterprises concentrating on product- and process innovation have undergone a lot of changes. According to GUPTA et al. (1986) product innovation is a multidisciplinary process. Although, all functional interfaces are important in the product development process, the research and development – marketing interface is one of the most difficult one. In the last two decades the incredibly fast penetration of the internet has more and more effects on the consumer attitudes. It encourages market researchers to apply such methods by which they could get as close as to the consumers to know their attitudes without taking them out of their natural habitat. In this study our aim is to concentrate on the first phase of the product innovation, which is the exploration of insights and attitudes. In this phase we can use the classical, conventional market research techniques if we want to get primary data, such as focus group interviews, questionnaires, in-depth interviews, but there are new methods as well. One of such novel methods is netnography. The biggest advantage of this research method is that the researcher can observe the consumer groups’ state of mind and decision-making mechanisms through publicly available communication sources in their natural environment. In this study it will be analysed how the directions of netnographic researches have changed by the dynamic changes of the internet. Besides, online participants’ attitudes towards healthconscious nutrition are analysed in practice. As a result of this study, special groups could be identified, which can provide a new perspective for the companies operating in this field beside the classical segmentation techniques. These groups can be the ones which draw up latent market requirements, and thus, helping the companies’ innovation processes.

    The aim of this study is to present a thermal analysis of a permanent magnet synchronous machine based on finite element method. The developed model can be used to predict temperature distribution inside the studied motor during the rated operation. Electromagnetic computation is carried out with the aid of two 2D finite-element (FE) simulations on the cross-section of the PM motor. To analyse the process of heat transfer in an electrical machine, empirical correlations are used to describe the convective heat transfer from the different surfaces of the PM motor. The heat transfer coefficient is determined using dimensionless numbers and Nusselt number. After the loss calculation, the temperatures of the machine are calculated by using 3D finite element method. The results obtained by the model are compared with experimental results from testing the prototype electric motor.

    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.
