Analysis of Social Media Activities - Through the Examination of Handball Clubs Competing at Different Levels
39-53Views:666In Hungary, handball enjoys special attention and support, this is true not only for our country, but also for Europe, and the sport is gaining more and more space worldwide. One of the biggest innovations of the last two decades is certainly social media, which has reformed the basic strategies related to information transfer and traditional marketing activities. The processes of content production on these platforms have radically changed, which every sports club should pay attention to, as they can gain significant advantages in terms of economics, marketing and community building if they are able to communicate well. Three sports clubs competing at different levels were compared during a qualitative study in terms of their social media marketing strategy activities, namely PICK Szeged, Balatonfüredi KSE – BFKA Balatonfüred and DEAC handball team. The basic concept of this research model was built on how the online marketing communication activities of club teams fighting for different professional goals at different levels differ from each other, as well as what are the development opportunities and aspects that can be used as effectively as possible on social media platforms. The handball club teams agreed on several research questions, but a significant difference could also be discovered in one area, in which the professionals responsible for social media disagreed or represented a different point of view. Looking at my results, it can be concluded that behind a successful online marketing strategy there is always serious preparation and planning work, as well as the diversification of content production on different platforms, because the consumer communities of the platforms are also different from each other.

Temporal Changes of Pyrite Oxidation Rate in Bolivian Sulphidic Mining Wastes
194-202Views:255Since the 70's, when huge sulphidic open pits were developed, the acidic rock drainage (ARD) become the leader problem of the sulphidic mining industry. Although the recycling is an essential technology, it cannot cover the demand alone, thus mining activity needs to continue. Acidity in mine drainage commonly requires most of the attention, but the main problem is the caused elevated level of metal mobility and leaching, which are generated by the increased rates of sulphide weathering under acidic conditions. The Itos mine is a polymetallic vein deposit in Bolivia, had been mined for silver and tin until 1990, leaving behind much and huge tailings and mine waste heaps, where quite often the pyrite content exceeds 10 %. Serious ARD effects take place in the mine waste heaps. These processes can be well characterized with the pH 1 or 2 of the seepage water, which forms serious alteration in the waste itself and the neighbouring rocks. In three consecutive years, the pyrite oxidation rate was investigated on the same 7 samples by humidity cell test. 5-6 months pauses were left between the humidity cell test periods, which mimics the alternation of wet and dry periods, typical for the place. The results give much more information, than the oxidation rate in the individual test periods, showing the changes by time. This applied method gave good result to characterize the behaviour of the waste in long-term. The column test was complemented with mineralogical analyses, such as electron probe micro analysis. The mineralogical and column test analyses show, that the changes of the pyrite oxidation rate split the samples into three different groups, one where the oxidation rate decreases, second where it increases with time and the third where oxidation rate is maximal and stays stable for several years.

CSR Reporting Practices of Hungarian Banks
70-81Views:352The disclosure of information on the exercise of corporate social responsibility (CSR) is the tool most frequently used by companies to promote understanding of the social and environmental performance of an organisation and to improve relationships with stakeholders. For most of the world’s largest companies, reporting on non-financial information appears to be a continuing trend, so it is essential to present the new corporate reporting trends of the 21st century. The disclosure of socially responsible information will be analysed, with a focus on the application of the Global Reporting Initiative guidelines related to CSR. Global Reporting Initiative (GRI) is the best-known framework for voluntary reporting of environmental and social performance by business worldwide. The main objective of the paper is to explore the corporate voluntary disclosure practices of the listed and non-listed banks in Hungary. The extent of voluntary disclosure has significantly improved for decades worldwide, but the situation is not that obvious regarding the Hungarian financial sector. This paper aims to describe the status of disclosure practices of corporate sustainability in the annual reports, sustainability reports or CSR reports of the banking industry in Hungary. Also, increased corporate visibility and financial risk increase stakeholder demand for transparency on the social impact of financial institutions and their CSR practices. Finally, the analysis and subsequent comparison of available CSR reports of banks will be presented.

Modeling the Thermal Behavior of Permanent Magnet Synchronous Motors
466-477Views:319The 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.

Analysing the Possible Connection Between Dark Triad Personality Traits and Ethical Attitudes of University Students
57-67Views:556In our paper we examined the possible connection between the Dark Triad personality traits and ethical attitudes among university students. The analysis of both topics has become the focus of interest in the past decades. Researchers consider the impact of many factors in the background of ethical attitudes and behavior. Among other things, personality is also a potential factor. The Dark Triad personality means the coexistence of the socially undesirable narcissism, Machiavellianism and psychopathy. Such people are characterized by self-love, aggression, the lack of guilt or conscience, so they are less likely to have ethical attitudes. In our research, this connection was examined by a questionnaire survey conducted among first year students of University of Debrecen Faculty of Natural Sciences and Technology and Faculty of Economics and Business. Respondents completed the validated Dirty Dozen questionnaire which was developed to measure Dark Triad personality and a questionnaire adapted from Lozier's research in which respondents were asked to evaluate school situations whether they are ethical or unethical and to what extent they are unethical. In our research, we were looking for significant relationships between the strength of the Dark Triad characteristics and the ethical judgment of situations. We also analyzed the differences between men and women and students of the two faculties.

Sectoral Analysis of Hungarian Professional Football Clubs - Hungarian Football Money League 2014-2016
284-296Views:1002Based 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.

Future Power Plant Portfolio Analysis from the Point of View of Minimum Cost and Emission Optimization
61-77Views:402The article examines the expected composition of the power plant portfolio in Hungary by 2030. The indicators considered are the life-cycle unit costs (LCOE) and the life-cycle specific carbon dioxide emissions (LCA(CO2)) of the power plant types. The minimum of these two indicators, as objective functions, is determined by a linear programming method for the power plant portfolio. The results show that the LCOE minimum for the power plant portfolios in 2030 is worse in absolute terms and better in specific terms than in 2021. In both absolute and specific terms, the LCA(CO2) minimum is more favourable in 2021. These results are met under the thirty and twenty-five percent electricity import scenarios. With twenty percent imports, the absolute values are worse and the specific values are better for both indicators. On the other hand, the results of the calculations for 2030 fall short of the 2030 Agenda of the Institute for a Green Transition. This is due to the delay in commissioning a new nuclear power plant and the transformation of industry with increasing electricity demand. For the portfolios under review, a minimum of thirty percent of domestic generation from renewable sources is met. This contributes significantly to the European Union's ambition for the sector to be net greenhouse gas-free by 2050.

Labor Market Effects of Organizational Health Promotion
99-107Views:578Nowadays, we can observe an increasing trend in the spread of non-communicable diseases. It is important to highlight the social factors that negatively affect health. Determinants includes income, education and the research-relevant working and living conditions. From a labor market perspective, unemployment and poor working conditions are a significant responsibility for the deterioration of mental and physical health. Health is also affected by employment conditions. Extended working hours have been shown to be harmful to health. Poor health has generates poorer work performance, a higher rate of sick leave, and higher health care costs. My primary goals in my research was to explore the labor market impacts of workplace health promotion and guidelines for corporate health promotion. Within health promotion, physical activity has played a prominent role. I’ve been used secondary data collection during my research. I have been performed a traditional literature analysis based on domestic and international studies. My results are suggest that the workplace health promotion has more positive labor market effects than increasing productivity and reducing absenteeism and health care costs. It is important to mention that health promotion could bring benefits to both employers and employees. Regarding corporate guidelines, there is no new approach directive other than the older literature sources. thus, it may be worthwhile to develop a new and different corporate process for effective workplace health promotion.

Survey of the Application Fields and Modeling Methods of Automotive Vehicle Dynamics Models
196-209Views:522In this paper, a review is presented on automotive vehicle dynamics modeling. Applied vehicle dynamics models from various application fields are analyzed and classified in the first section. Vehicle dynamics models may be simplified because of different reasons: several control/estimation/analysis methods are suitable only for simplified models (e.g. using control-oriented models), or because of the computational cost. Detailed/truth models of vehicle dynamics represent another field of vehicle dynamics modeling, these models play an important role in the virtual prototyping of vehicles. In the second section, the main modeling considerations of vehicle dynamics are presented in longitudinal, lateral and vertical directions. Various physical effects must be considered in the case of vehicle dynamics modeling, a lot of these effects are significant only in a specific direction of the vehicle body, which is the main potential of model simplification. The section presents vehicle modeling considerations in all of the three translational directions of the vehicle body.

A Case Study on Human Resource Management Practice of a Sport Organization
410-425Views:1197Human resource with the adequate ability and skills is of decisive importance in all organizations, irrespective of the field of activity in which they operate. It is no different with the life of sports organizations. The human resource management of sports organizations is peculiar which is influenced by, on the one hand, the operating form of an organization, on the other hand, the nature of employment. Those well-known jobs can be also found in the sport organizations which are necessary to operate an organization and carry out the general tasks, at the same time, the amateur or professional athletes turn up as specific human resources. Aim of the study is to explore the specific characteristics of the human resource management of a particular organization, namely Debreceni Egyetem Atlétikai Club Sport Nonprofit Közhasznú Kft. (University of Debrecen Athletic Sport Non-profit Public Benefit Purpose Ltd., hereinafter: DEAC Ltd.), primarily focusing on the traditional HR functions. After reviewing the domestic and international specialized literatures, the practice of the examined sport organization will be described by means of case study, document analysis and managerial interview methods. Based on the results, it can be determined that there is no separate HR manager in case of the examined sport organization, due to its size, but the managing director carries out the tasks as an economic and HR manager in one person. From the aspect of organizational operation, the practice of HR functions is similar to the practice of other SME business organizations, at the same time, the management of athletics as human resources means its specific characteristic where the managements of labour supply, career and talent has other interpretation.
