    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.

    Digitalization 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.

    In terms of production value, the food industry is the third-largest in Hungary, the first in Hungary in terms of the number of employees, and the first in Europe in the processing industry, as well as a significant user of resources. The research examined the state of art of digitalization readiness, focusing on I4.0 technologies, which supports the management to operate more efficiently the enterprise and to make better decisions. So the focus was on integrated enterprise information systems, management support systems, business intelligence systems, industry 4.0 technologies, and issues related to their application. The analysis based on an online questionnaire survey the request sent to 4.600 enterprises, the response rate was 5% which was representative of the branches of production, covered the Hungarian food and beverage manufacturing sectors in 2019. The companies were asked the most critical technologies in development, going towards Industry 4.0. The research tools were LimeSurvey, Mailing List Server, Excel, Power BI (Desktop, Publishing Server to distribute the results). The used analysing methods were making calculations, pivot tables, models, dasboards. We found that a significant portion of businesses, 78 %, use mobile devices in the manufacturing process. The three most relevant digital technologies are geolocating (GPS, GNSS), cloud computing, and sensor technology. The current level of digitalization and integration cannot be said to be high, but respondents are very optimistic about expectations. Improvements are expected in all areas in the next 2-3 years in terms of digitalisation and integration. Vertical integration involves, first and foremost, cooperation with partners in the supply chain. Horizontal integration means close, real-time connectivity and collaboration within the company. Unfortunately, between 6% and 15% of SMEs (approximately 9% on average) and large enterprises, 36% have a digital strategy. According to the survey, the sector needs significant improvement and creating a digitalization strategy.

    The impact of macroeconomic factors offers insight into the performance of an economy. This study investigates the dynamic short- and long-term effect of trade openness, external debt, and foreign direct investment (FDI) within Ghana's economy. Utilizing Autoregressive Distributed Lag (ARDL) bound testing and Granger causality analysis, the study examines data spanning from 1991 to 2022. The results of the ARDL cointegration test reveal a long-term relationship among the variables. However, in the short term, the findings present a mixed effect of FDI and trade openness, with both positive and negative impacts. In the long run, FDI and external debt exhibit a positive influence, whereas trade openness appears to impede economic growth. Furthermore, the Granger causality test identifies a unidirectional causality relationship between the variables and economic growth. The study suggests that the government implement investment-oriented and trade policies to stimulate economic growth.

    Diagnostics of batteries using advanced methods have gained remarkable roles in the past few years. This study focuses on the type of measurements, tests and methods to reveal and classify them. During manufacturing and operation several faults could emerge in batteries including non-optimal operation conditions, operators without experience, and finally, random changes in batteries under physical and nonphysical conditions. Improper handling of batteries and battery cells man cause operation failures or, in the worst case, accidents. To reveal these problems several methods are applied in industry and in scientific laboratories. For a comprehensive analysis of battery management, artificial intelligence and Industry 4.0 methods can be used very effectively. Big Data analysis in its standard form is not a new achievement, but other mathematical tools could be applied to control monitoring such as Fuzzy Logic or Support Vector Machine (SVM). They are efficient tools to analyse the deviation of batteries condition because it can detect sudden changes, parameter deviations and anomalies, and the user’s behaviour and habits. This article gives a description about the most important battery testing methods and the connection between Big Data and Operation Management with Artificial Intelligent (AI) methods.

    This paper aim is to review the implementation of artificial intelligence (AI) in the Human Resources Management (HRM) recruitment processes. A systematic review was adopted in which academic papers, magazine articles as well as high rated websites with related fields were checked. The findings of this study should contribute to the general understanding of the impact of AI on the HRM recruitment process. It was impossible to track and cover all topics related to the subject. However, the research methodology used seems to be reasonable and acceptable as it covers a good number of articles which are related to the core subject area. The results and findings were almost clear that using AI is advantages in the area of recruitment as technology can serve best in this area. Moreover, time, efforts, and boring daily tasks are transformed to be computerized which makes a good space for humans to focus on more important subjects related to boosting performance and development. Acquiring automation and cognitive insights as well as cognitive engagement in the recruitment process would make it possible for systems to work similarly to the human brain in terms of data analysis and the ability to build an effective systematic engagement to process the data in an unbiased, efficient and fast way.

    The EU energy policy prioritizes the following principles: sustainability, competitiveness and security of supply and addresses the reduction of greenhouse gas emissions as a priority. The related EU policy (including the White Paper on Transport) outlines these principles, identifies goals and opportunities for action. At company level methodological guidelines and standard procedures can be used to assess the carbon footprint of the organization, to generate efficiency goals and to prepare action plans. In the Hungarian policy framework, a comprehensive National Sustainable Development Framework Strategy defines the basic principles for the analysis of the sectorspecific or regional strategies. Sustainable Energy Action and Climate Plans (SECAPs) integrate energy and climate issues and include interventions and improvements for the better use of renewable energy sources in transport at municipal level. As a summary it can be stated that exploration of the policy background would needed to influence the use of renewable energy sources for transport and definition of the development goals can help economic organizations to transform their mobility patterns and reduce related carbon footprint.

    Like large companies, the small, and medium-sized businesses need also all the information to ensure the efficiency and effectiveness of their business by making sound management decisions. Compared to large companies, SMEs have significant development potential, which can be created in part by the companies themselves, possibly through the introduction of new-modern management - business administration methods or economic policy measures (= targeted and efficient support system), which, by stimulating R & D & I processes, serves to increase competitiveness and contribute more and proportionally to domestic GDP and exports. The analysis presented in the study covers the controlling knowledge of the leading SMEs of the Northern Great Plain Region, the conscious or unconscious application of controlling tools, the assessment of succession, customer and supplier valuation and certain areas of managerial accounting. Overall, it can be concluded from the small sample size that the use of controlling tools is proportional to the size of the business, but nevertheless, many mid-size business executives do not require the collection and analysis of insider information that could explicitly help decision making for example  through advanced costing procedures.

  • Introduction to Design and Analysis of Torsional Vibration Dampers in Vehicle Industry

    The crankshaft of today’s internal combustion engines with high performance output are exposed to harmful torsional oscillations originated from the unbalanced gas and inertial forces. To avoid the fatigue damage of engine components, caused by the undesired vibrations, torsional vibration dampers can be applied. Viscodampers are one type of the torsional vibration dampers, which operational fluid is silicone oil. For cost-effective R&D activities and production, finite element and finite volume numerical discretization methods based calculation techniques must be involved into the engineering work supported by the modern computer technology. The aim of this paper is to provide an insight into the multidisciplinary design and development process of visco-dampers in vehicle industry applications. Four different examples as structural, fatigue, CFD analyses and structural optimization have been introduced in the present work. It turned out from the static structural and fatigue analyses, that the investigated damper has safety factor over the limit for both static structural and fatigue analyses, so it is suitable for the given load conditions. In the structural optimization process 34.36% mass reduction has been achieved. According to the coupled fluid dynamic and heat transfer simulations a rather stagnating air zone evolved between the engine and the damper during the operation, which can cause efficiency reduction of cooling fins mounted onto the housing. In light of the numerical results, the suitable damper position has been determined for the highest heat transfer.

    Additive manufacturing (AM) is a process in which the product is composed of overlapping layers of a material that is added using devices such as 3D printers. Its process has been evolving for decades and nowadays it can be used for several applications and with different materials. One modern usage is for medical and dental purposes. Since it became possible to print metal, it has been a good solution for bone implants, once it must be done with biomaterials and can now replicate the bone structure, for that unit cells should compose the implant. Both conditions are now possible to be achieved by AM, and the current study will analyze, using finite element method, the possibilities to create specimens for tests which the final product would result in a 3D printed bone implant.

    Risk and uncertainty are subjects of philosophic and theoretic discussions long time ago. Both concepts have the intention that nature and effects of future happenings have to be analyzed and forecasted. Difference is though that analysis is possible by different means. Uncertainty is frightening and hard to be analyzed. On the other hand, risk is better served by data, easier to find a methodology that makes it a more acceptable and manageable object. Theoretic part of the article states that risk and uncertainty entitle a risk spectrum. The next statement is that this spectrum has layers piled on one on the other, from which risk and uncertainty are the ones on the sides.

    The starting point for the need for social responsibility is to combat the deterioration and destruction of social and environmental values. The social and economic factors induce both society and the economy, including companies, to prioritize their social role. Corporate responsibility needs to be incorporated into the company's strategy so that it can be more planned in the long term, since CSR can thus maximize its impact, ultimately leading to maximizing profits. To be able to develop a strategy, we must first look at the broader environment to which we can apply PEST analysis, by analyzing the social, legal, polo-social and social environment. To take a closer look at the company's narrower environment, we can use the SWOT analysis to identify the company's strengths, weaknesses, opportunities and dangers. Based on these, the Hoshin Kanri method can be used to transform the company's own CSR strategy both short and long-term in order to become part of the corporate culture.

    The height determination of control and detail points is essential during the process of planning and manufacturing in the practice of civil engineering. Planning maps are drawn for the former, while the intended plan is set out on the ground during manufacturing, and after the manufacturing the completed installation is mapped. Using the same reference system in all three steps, both horizontally and vertically, is recommended even though in some cases it is unavoidable to change from one reference level to another. Regardless of the fact that both refer to the mean sea level of the Baltic Sea, this can create difficulties, since the difference between the EOMA and Bendefy networks used in Hungary shows varying values depending on the geographical location. The aim of the analysis is to determine a constant difference regarding the analysed settlements based on the common points of the networks.
