    The football Euro 2020/21 has been said to be more environmentally friendly, as it was spread all over Europe, thus no new stadiums needed to be built. On the other hand, more traveling became necessary. How does these effects behave with each other? Was the attempt to reduce emissions successful?      
    This paper seeks to compare the goals for UEFA 2020/21 for environmental friendliness and its success. A mixed research strategy was adopted in this paper where qualitative analysis was done on existing literature review and also quantitative approach where assumptions were drawn from literature review to estimate the environmental impact. This paper found that UEFA's initial estimate of 425,000 tons of carbon dioxide emissions in traveling for the Euro Cup 2020 was a bit higher than the actual amount of carbon emissions from our calculation of 143,531 tons. What stands out is that its findings agree with UEFA's estimate that Euro Cup 2020 emissions were lower than that of 2016 which emitted 517,000 tons of carbon dioxide for traveling. This gives a greater reason to conclude that UEFA met its goal of reducing carbon emissions. The overall carbon dioxide emissions in traveling and constructing stages were 1,275,988 tons in Euro Cup 2020 and 2,803,000 tons in Euro Cup 2016. This further affirms the overall carbon dioxide emission reduction by half in Euro Cup 2020 as compared to Euro 2016. From our findings, we can conclude that the Euro Cup 2020 indeed succeeded in reducing overall carbon dioxide emissions by half. Despite the success, this paper views that the carbon emissions are still high for a single event and hence there is room for reduction of carbon emissions to lower levels as possible. we can conclude that the Euro Cup 2020 indeed succeeded in reducing overall carbon dioxide emissions by half.

    Generally, the most frequently used structural materials are metals which have high strength and stiffness. However, there are many cases when other important properties come to the front, as well as high deformation capacity with elastic behavior, high viscosity namely good damping effect. Due to its above mentioned properties, rubber is widely used in vehicle and automotive industry. Vehicle components made of rubber usually exhibit large deformations. Cyclic finite deformations generate temperature in hyperelastic materials. Furthermore it is necessary to take into consideration the effects of ambient temperature. The mechanical properties of rubber depend on temperature and temperature changes can accelerate chemical alteration processes which lead to the material deterioration and fatigue processes. Research on fatigue behavior and fatigue properties of rubber has a great significance for predicting fatigue life and improving durability of rubber products. There are several studies on the fatigue behavior of rubber-based materials, but there is less research in the fatigue life prediction considering the influence of temperature and temperature changes. First purpose of this paper is summarizing the influence of temperature and temperature changes on the fatigue behavior of rubber. The second purpose of this study is to provide an overview of the state of the art on the fatigue life prediction of rubber with primary focus on the different methods available for prediction of fatigue life under the influence of temperature and temperature changes.

    There is a great concern about utilizing different waste materials all over the world. Stockpiling in landfills is not a final solution, therefore researchers try to find alternative methods to utilize these materials [1-5]. One potential area may be road construction. Fillers are one of the most important components of asphalt pavements. It has a dual role. First of all, these fine grained mineral materials (d<0.063 mm) enhance the cohesion with bitumen. Second is to fill the gaps between the particles to produce more compact mixture [6]. The aim of this research is to reveal the possibility of utilization of aluminum dross as a potential asphalt filler. This material, which is a by-product of aluminum casting process, is produced in large quantities year by year and its storage in landfills is not a proper solution. Therefore, there is an increasing demand to utilize this material. During the research material structural tests were made, which can characterize the samples (limestone powder, dross), and the cohesion between bitumen and filler can also reveal. Particle size distribution, BET specific surface area and porosity were investigated. Scanning electron micrographs were taken and oil adsorption test were also made.

    At the investigated public service providers’ personal customer service they did significant changes were made in the field of quality control since April 2017. A method which existed and was used for a long time was modified, which had one of the most important objectives from a management aspect to help the development of the administrators in order to provide high quality. During our research we mostly focused the development impact of the modified system. We wanted to obtain an answer whether the new system is better for promoting the development of the administrators than the former method and to what extent administrators require feedback related to their job as well as whether this system is properly inspected and controlled by leaders. During the research we targeted three focus points related to the development aspect: self-check, constructive feedback and the degree to which seated work is controlled. Based on the results of the investigation we draft such suggestions which can promote efficiency if necessary and possibly even make the operation of the system more efficient.

    Nanomaterials have unique application features which can mainly be associated with their size properties. These materials have much higher surface than the normal particle size variant of the same materials. Due to these properties, nanomaterials are widely used in the industry. Food industry and the agrarian sector are using these materials increasingly. The main goal of nano size components and additives are the improvement of some parameters of the food manufacturing process, the elongation of the best before date of the food and the improvement of the texture, stability and the consistence of the food. Probably, nanomaterials will play an important role in the development of the food industry, moreover, it can be anticipated that nanotechnology will also appear there and will influence the whole food chain. It should be noted that food industry is using several nano size class materials which are not referred to as nanomaterials. Some examples are the micelles of some proteins, like milk protein, and fatty acids. Considering all these, the aim of our work was to present a thorough review and summary of the current applications.

    The reason behind is that they have their own principles, strategic goals and industrial environment that they have to manage on daily bases. The current labour and talent shortage across Europe forces local companies to supply their demand of manpower from foreign countries – encouraged by the ’four freedoms’ of the EU. In consequence of the globalisation, we have to keep in mind that running a talent management system has its challenges. For instance, employees with different cultural background might have unconventional needs. Due to the cultural, demographical and economical differencies, we must know the structure of our labour force to use the most beneficial tools to induct, motivate or retain our human resource. The aim of this research is to analyze Europe’s and China’s talent management systems to reveal similarities and differencies between them and pick the most notable ones. From the point of comparison, analysing China would be important for European countries to discover further possibilities, as nowadays China has one of the most dynamically developing economy with enormous population behind. The primary result of the research is that deficiency of talent is irrespective of the size of the population and it causes difficulty in both European and Chinese fields, therefore it proves to be a real and general challenge needing attention at organizational level. Furthermore, identifying regional patterns considering peculiarities, the framework of talent management systems can be defined and be found summarised in the article.

    Our research aims to identify the critical interfaces between sales and marketing that need to be improved in order to ensure productive cooperation. The relationship between the two departments is full of conflicts and interdependencies. The improvement of communication is of strategical importance, as it is key to staying competitive in the market. The effectiveness and quality of the sales-marketing cooperation is a key factor that is negatively affected by personal and organisational factors as well as a lack of information and conflicts. In addition to the key factors of managing the sales-marketing interfaces, we have also identified the actions that can promote their improvement, including strategic and organisational roles and responsibilities. Our empirical research results show that regular information exchange, more common and interdisciplinary meetings, and a clearly communicated and implemented corporate vision have a positive effect on the coordination and integration of the sales and marketing departments. Consequently, management is reponsible for establishing a corporate vision, i.e. a comprehensive management culture that is clearly communicated across the board in order to increase the employees’ sense of belonging. Of all elements of management culture, the most important factors are coordination and the establishment of a common strategic sysyem. All in all, corporate profit, which is of key importance to the employer, is largely dependent on the successful integration of the sales and marketing departments, which can be achieved through the implementation of the above factors.

  • Analysis of Vibration During Turning Process of Different Materials

    In this article, we would like to introduce the problems caused by vibrations in case of polymer turning processes. Nowadays there is a lot of research in this topic, to avoid the unnecessary phenomena of vibrations. The two most common methods are the Spindle Speed Variation (SSV), and the Vibration Assisted Machining (VAM). In case of SSV, the CNC machine can increase and decrease the speed of spindle continuously during turning which can significantly reduce the effects of chatter. This method is beneficial for longer workpieces when there is not any support except the chuck. Vibration-assisted machining can be used to minimise the problems caused by vibrations. VAM combines precision machining with small-amplitude tool vibration to improve the fabrication process. It has been applied to some processes ranging from turning, drilling to grinding. Based on the enumerated above we made some trial measurements about the basic vibrations of the turning tool shank. The tests were done on an NCT EUROturn-12B CNC machine which can found in the workshop of our institute. The tested material was Polyamide 6 because this is the most commonly used polymer in the industry. In the future, we would like to test some other basic and composite polymer materials too. The equipment was served by a specialist from SPM Budapest Kft. With these tests, our goal was to make sure that the equipment and the measuring setup are suitable for our future research.

    In this study I deal with the ethical leadership. I give an insight into the approaches of ethical leadership, give a literature review on the concept of ethical leadership, and introduce the measurement methods used in the most important empirical researches related to this topic. I also try to report on the first results of my research (I plan to describe features of Hungarian leaders based on a smaller sample). How does this relate to the challenges of Industry 4.0? I give the answer from the fact that, with the advent of these new technologies (which in themselves have ethical questions), among these new challenges, the focus of the manager's attention will continue to be partly on their employees. If they set an ethical example for their subordinates, they encourage their employees to act ethically, which gives the company a competitive edge in many ways, both in the product/service market and in the labor market too. So, with my study, I would like to draw the attention of executives and managers to the fact that new technologies and the human factor together bring new successes, and that one possible way of doing this is by consciously managing their company ethically and developing an ethical organizational culture.

    Nowadays, the energy consumption of global population is depending on fossil fuels, but the role of renewable energies has been increasing rapidly, primarily due to the depletion of fossil fuels, the appreciation of environmental problems and climate policies. Biomass is the fourth most important energy resource in the world, provided an estimated 70% of global renewable energy supply. However, the annual growth rate of biomass is lagging behind modern renewable energy sources. The type of biomass is very diverse and can be processed and utilised by different methods. Currently, in the "green chemistry" industry (the replacement of petroleum-based, synthetic chemical raw materials with bio-based compounds from plant biomass), the importance of combustion, pyrolysis, biogas, bioethanol, biodiesel and basic chemical compounds production have been increasing. The objectives of the present research is to analyse the global and domestic status of renewable energies and biomass production, furthermore the possibilities of utilization of perennial, herbaceous biomass plant, the giant reed (Arundo donax L.), with which has been conducting research for numerous years at the University of Debrecen.

    Over the past 25 years, many renowned scientists from a number of research institutes have developed a new research method, a new family of methodologies which is the MFA (Material Flow Analysis). The importance of MFA is given by the extent of excited material flows created by mankind. The basis of MFA's growing success is a radically new, interdisciplinary vision that requires collaboration between the natural and social sciences (ecology, thermodynamics, and economics), not only as an effective tool for examining material efficiency of production and environmental pressures, as well as the security of supply of the strategic material requirements of the system under investigation. In our article, we conduct an enterprise level analysis of the input and output side material flows and materials of a service company in Debrecen for 2018 using the MFA method. MFA indicators capture environmental pressures in a natural dimension, that is, in terms of mass, energy, or land, respectively, in terms of kilograms or tons, of the company's raw materials and their changes, or material inputs.

    The research is examining traditional arable crops and woody plants on the basis of their marginal contribution. Calculations of income, expenditure and revenue were made on the grounds of sectoral technologies, which were the basis of the value of marginal contribution of the given sectors. As the linear programming model is quite comprehensive, we used this method for our calculations. To compile our model, we have gathered all the necessary information from farmers of the region of the Northern Great Plain. The missing data was completed from the databases of the Hungarian Central Statistical Office (KSH), Institute for Agricultural Economics Research and Information Technologies (AKII) and the Statistical Office of the European Communities (EUROSTAT). In some cases, we also used data of the Agricultural Administration Office and the Ministry of Agricultural and Rural Development. Our goal is to compile a 12-year production structure that suits for the characteristics of the region of the Northern Great Plain by achieving the maximum marginal contribution of a feature-farm.

    Western-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.
