The Importance of Energy Management in Hungary
72-79Views:130One of the important elements of our everyday life is energy, but the amount of it is constantly decreasing, so it is advisable to include renewable energies in our energy management in addition to traditional energy sources. In the field of energy management, the use of renewable energies deserves attention because their share is increasing, although their percent is small. At present, Hungary and the European Union's energy policy contain guidelines that aim to increase the utilization of renewable energy sources. These directives contribute to achieving environmental and climate protection goals, job creation, territorial and urban development, and the reduction of dependence on energy imports. In my article, I would like to present various calculations in the field of energy management as a result of the previously described information and I would like to explore the energy management contexts that have come to the fore when examining residential energy consumption

X/Y emberkép hatása a teljesítményre változó környezetben
429-440Views:535A vezetési stílus kérdésköre kutatott terület, több elmélet és modell is született az elmúlt évtizedekben, ezek közül az egyik legismertebb a McGregortól származó X/Y elmélet, amely nagy múltra tekint vissza, mégis máig foglalkoztatja a kutatókat. Az utóbbi években számos olyan elemzés is megvalósult, amely a stílusnak a szervezeti teljesítményre gyakorolt hatását vizsgálta objektív vagy szubjektív mutatók használatával. Ebben a munkámban az X/Y elmélet alapjainak, a családi vállalkozások meghatározásának és a teljesítménymérésre tett legutóbbi kísérleteknek a rövid áttekintésén túl családi vállalkozások vezetőinek körében végzett empirikus kutatásomat mutatom be. A kutatási kérdéseimmel (K1, K2) arra kerestem a választ, hogy van-e összefüggés a vezető McGregor-i emberképe és a vállalkozás teljesítménye között. A teljesítmény mérőszámaként korábbi kutatások nyomán objektív számviteli adatot, az értékesítés nettó árbevételét vettem alapul, a 2008-as gazdasági válság idején a vállalkozók vezetői is elsődlegesen ebben – az értékesítési forgalom változásában – mérték a válság hatásait. A korábbi, X/Y emberkép hatásait vizsgáló kutatások a válság lehetséges befolyásoló hatásait nem vették figyelembe, indokolt lehet ilyen tekintetben is elemzéseket végezni, ezért az első kérdésemben (K1) az X/Y emberkép és a 2008/2012 -i teljesítmény közötti összefüggést vizsgáltam, ezzel lehetőségem nyílt a 2008-as gazdasági válság induláskori (2008) és a vezetők előzetes várakozása szerint fellendülést hozó 2012-es év teljesítményének összevetésére. A kapott eredmények a korábbi kutatási eredményekhez hasonló képet mutatnak, az Y elmélet képviselői eredményesebbek, amelyet a kereszttábla-elemzés szignifikáns eredményei is megerősítettek. Második kérdésemben (K1) a gazdasági válság időszakának átugrásával a K1-hez képest más időhorizonton (2008/2017) vizsgáltam meg az X/Y elmélet szerinti lehetséges összefüggést. Ez utóbbi (K2) esetben a K1-től eltérően statisztikailag nincs kimutatható összefüggés a változók között, viszont az arányok arról tanúskodnak, hogy az Y emberképpel rendelkezők ebben az időtávban is sikeresebbek forgalomnövelés tekintetében. Az attitűdök nagyon nehezen formálhatók, viszont az X emberképpel rendelkező vezetőknek érdemes lehet felülvizsgálni az emberekről alkotott vélekedésüket, változtatni a hozzáállásukon, mert az eredményekből kitűnik, hogy mérhetően sikeresebb az, aki Y emberképpel rendelkezik. A vállalkozások többségénél aktuálissá váló generációváltás esetében a kapott eredmények tükrében azt is érdemes megfontolniuk a stafétát átadó vezetőknek, hogy milyen emberképpel rendelkező utódra bízzák a vállalkozás további irányítását.

Comperative Economic Analysis of the Determining Leagues of European Clubfootball
22-35Views:481Nowadays sport is not just all about entertainment, or about social cohesion but also it has serious economic and business aspects. Sporteconimics is an individual concept and sector. Sport businesses are contributing more and more to national incomes. Football business are specially important parts of this complex system called sporteconomics. The aim of my research is to create an economic and also comparative analysis of the five top European football leagues, also called as the “Big5” which are responsible for 74% of the total football revenue in Europe. By the analysis of the 2019 UEFA report it can be stated that in these leagues more than 60% of the competing clubs achieved positive operating profits, but the structure of their revenues warns them to look for opportunities to increase their operating revenues. According to the data it is clear that wage cost is the most significant cost element in the industry as they cover 53-68% of their total revenue. These statements set the course for the economic development of European football. The management of these outstanding football clubs may give example to the ones falling behind including Hungarian football businesses.

Situation Report of European Club Football (2017 – 2019)
61-71Views:261The most professional and profit oriented sector of the sports industry is football. International summary analyzes of the sector show a steady increase in revenue over the last 20 years. Yet the real turning point in terms of the profitability of European club football was in 2017, when the aggregate result of the clubs playing in the top European leagues were realized as a profit. However in recent years, the sector has faced serious competitors. The esport industry draws attention to itself with the growth rate of the base of its’ followers and related revenues. Also the fitness sector outperformed the football sector in 2019. In this article I reviewed european football between 2017 and 2019, in order to explore the characteristics of the football sector, to ascertain its revenue-generating capacity, its change in its revenue structure, and to answer the questions that if this sport will maintain its dominant position in the European sports market. My research method was document analisys of annual reports published by UEFA and Deloitte, which allowed me to examine data from more than 700 clubs in 55 countries. In overall it can be stated that the european football industry is maintaining it’s position, but it should allocate resources to stabilize its follower base instead of fearing the endagerment by other sports.

Examination of Labor Market Demand in the Case of the Construction Professions
512-519Views:169Tanulmányomban megvizsgálom az építőipari termelés és azon belül is a lakásépítést befolyásoló tényezőket 1921- től napjainkig. Ezen számok tükrében az építőiparban dolgozók számának folyamatos változásait értékelem, illetve hogy a vizsgált körülményekre hogyan tud reagálni a munkaerőpiac. A cikkben célom rámutatni, hogy a különböző hatásokra a szakemberek száma nem tud rugalmasan változni. A nagyobb beruházási években, illetve a jobb kereseti lehetőség miatt kivándorolt szakemberek hiánya komoly gondot okoz. Ennek ellentétes pólusa, amikor a gazdasági válság éveiben a beruházási kedv hiányában munkaerő többlettel rendelkezik az építőipar.

Comparison of the information content of the notes on the accounts between information technology services and sports activities
689-700Views:186Annual accounting statements are an important source of information within business relations amongst companies. However, it should be noted that due to their aggregate nature, the necessary information and through that the necessary knowledge 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 contributes to the more comprehensive interpretation of the other part of the annual statement. Beyond that, the notes to the financial statement have to help the presentation of a reliable and realistic overall image. In the notes to the financial statement, depth and detail of the disclosed information are not specifically stated, therefore their professional evaluation is left to the given enterprise. My basic purpose is to illustrate a comparison of the information content of the notes on the accounts between information technology services and sports activities. By means of text mining, we analyse the extent to which the notes on the accounts are in conformity with the Accounting Act.

Sustainability Goals - Can we Reduce Malnutrition?
268-276Views:286Nowadays, some parts of the world hunger still exists. One of the milestones of the Millennium Development Goals (MDGs) is eradicating hunger. These goals include a road map for progress and documenting specific steps to combat hunger. Another type of hunger that has been very common in these days is hidden hunger. Eradicating extreme poverty and hunger is still an illusion. The number of people living in extreme poverty and malnutrition has fallen slightly in recent years. Measuring hunger is a very complex issue. The Global Hunger Index is a tool to comprehensively measure and monitor hunger at global, regional and national levels. Despite noticeable improvements, the question remains: will the world achieve its Sustainable Development Goals (SDGs), including the eradication of hunger, by 2030? Despite these efforts, even in economically developed countries, hunger or food insecurity still exist.

The Analysis of the Seasonal Changes of Microbial Communities in the Activated Sludge of Small and Large Wastewater Treatment Plants
321-340Views:123In our research the seasonal changes of the microbial communities in the activated sludge of one large and two small wastewater treatment plants are observed and analysed. During the research, 14 months of data were processed. After the sample analysis and data processing, the research revealed the efficiency of the ecological system, and also showed the seasonal changes of the community structures. The results of the statistical analysis show, that the seasonality is less observable in the case of the larger system. Presumably, the larger bioreactors have more stable microbial composition. In addition, we searched for more connections between the components of the ecological system, the changing in the weather, and also in the efficiency in the process for treating wastewater.

Testing Methods of Green Supply Chain, in Particular Supplier’s Selection an Evaluation Tools
240-254Views:378Today, more and more articles have emerged in the field of sustainability and sustainable development. Sustainability plays an important role in supply chain management too. Green Supply Chain Management (GSCM) has emerged as a key approach for enterprises seeking to make their businesses environmentally sustainable. The notion of GSCM implies the insertion of environmental criteria within the decision-making context of the traditional supply chain management. Enterprises are increasingly expected to extend their sustainability efforts beyond their own operations to their suppliers and customers to their sustainability expectations. Literature of green supplier evaluation and selection methods number is large, though the number of environmental factors are relatively limited. Recently in supply chain management decision making, approaches for evaluating green supplier performance have used both qualitative and quantitative environmental data. Given this evolving research area, the purpose of this article is to analyse research conducted in international scientific journals focusing on the selection and evaluation of a green supplier. The purpose of this article will answered two questions: Which selection methods are commonly used? What environmental and other selection criteria for green supplier management are popular?

Building’s Constructions and Structures. Part I. The Classification of Buildings by Supporting Structures
56-78Views:341In the paper we deal with the structures interpreted among the buildings constructions. In the present, first part we classify the buildings constructions by their functions. Two main groups can be formed. Analysing supporting construction group can be shown that the building can be well classify by supporting constructions. The classification based on vertical supporting constructions like wall and column gives fourelement classification: wall frame, column frame, mixed frame and frame without vertical supporting constructions. This classification is very simple. Take into consideration of the buildings technology of walls and columns there can be given a classification whit more elements. Different subgroups can be interpreted using connections of walls and columns with floor construction in the certain groups.

Transformation of the Decisional Leadership Role
26-40Views:86Leadership decision-making is important for the successful functioning of organizations, so it is necessary for leaders to understand the factors that impact their decisions. Decision-making is always the responsibility of the leader, but in a changing world, it becomes an even more crucial factor for success. Making good decisions requires time, experience, and thorough problem-solving skills. In my research, through the analysis of scholarly sources, I have identified several role factors that clearly influence the decision-making process and its implementation. Furthermore, I have developed a self-designed questionnaire to examine the decision-making role in modern organizations. I analyzed the data from 230 respondents using various statistical methods. Based on my findings, conflict management, risk-taking, and a thorough understanding of the problem strongly determine leadership decision-making processes. The ability of leaders to effectively manage conflicts significantly impacts their decisions. Risk-taking is also of key importance, as leaders need to recognize the risks associated with a given situation and make decisions accordingly.

Quality Indexes of Warehouse Services
1-13Views:447There was a wide range and rapid development in the field of warehouse management in the recent decades as a result of strong and spectacular improvement of establishing and operating warehouses, in addition to increasingly complex logistic processes. In my research, I analysed the complex problems of determining the performance expectedfromoperatingthewarehousetechnologicalsystem. Thisdecisioninvolvestheselection of the essential performance indicators suitable for performance measurement and the determination of the expected performance level based on these indicators through the example of an examined enterprise. During my research, I concluded that the logistic performance measurement of warehouse processes is a very difficult process, because all enterprises have to define and use indexes which adapt to the enterprise profile well and reflect the performance to be measured. This decision is of key importance, since the warehouse system and its operation principles have to be adjusted to this expected performance.

Examining the employees and sectors of the economy according to the digital competence in the EU memeber states
344-357Views:259In this study, the challenges of digital development and its sectoral effects were examined between 2015 and 2017 in the EU Member States, based on data of OECD, Eurostat, and the World Bank. The connection between the countries' digital development and sector dominance was analyzed. I found - in line with international research - that in countries that belong to the developed group, the high value-added service sector is dominant. The statistics of developing countries’ supported the assumption, that industry is the engine of the economy. The analysis of the underdeveloped countries revealed that agriculture and industry are the most important sectors compared to other countries. Measuring the demand of developed countries for ICT professionals, I examined the relationship of individuals with different digital competencies to one kind of self-education. In line with international research, my database showed that digitally unskilled people are the least likely to take advantage of online courses. As a continuation of the research, it would be worthwhile to carry out this study in other economic areas as well. Especially in areas where salaries for high-digital occupations do not differ significantly between countries in the region.

Labour Economics - From the Technological Development Perspective
1-11Views:52The impact of technological advancements on the labor market and innovation processes is a critically important research area. The aim of this study is to examine the emergence and frequency of technological innovations in scientific publications, with a particular focus on the Journal of Labour Economics from 2000 to 2020. The research employs content analysis methods, searching for eight different terms and expressions related to technological development (e.g., technology, artificial intelligence, machine learning) across 1405 articles. The study also analyzes the number of occurrences and annual publication trends of these terms. A total of 9469 instances were identified, indicating that in 64,7% of the cases, at least one technological term appeared. An analysis of annual trends reveals an increase in the usage of certain keywords (technology, artificial intelligence, and machine learning). In a smaller subset of articles, only 1%, technological terms were mentioned at least 50 times. The results suggest that although the topic of technological development plays a significant role in labor market research, the frequency of its appearance and the depth of analysis vary considerably. The increase in the appearance of technological terms is predominantly observed in the fields of artificial intelligence and machine learning. These findings are specific to a single journal, indicating the need for further research involving other labor market journals to ensure representativeness.

Consumer Perception of Electric Cars in Hungary – Theoretical Considerations and Empirical Results
1-23Views:360Electric cars are becoming increasingly popular in the automotive industry and among consumers; partly as a result of their environmentally friendly characteristics. The aim of the study is to compare the main characteristics of electric and conventional cars in the context of environmental protection. In the first half of the study, we present the life cycle of electric and conventional cars and we compare the overall environmental impact traditional an electric vehicles. We point out that although the operation of an electric car does not pollute the environment locally, the manufacture, charging and disposal of batteries required for operation raises several issues related to environmental pollution. In the second part, we examine the respondents' attitudes towards electric cars based on our own questionnaire research. On the basis of the answers, it can be said that consumers still consider electric cars expensive and are aware that electric cars address some pollution issues to a small extent.

Sustainability, sustainable supply chain management
322-328Views:807With the rapid development of the world economy, the growing scarcity of natural resources and the degradation caused by pollution, environmental protection has become a major concern for countries and regions of the world. Sustainability is a common subject in many parts of the world and the various research areas among policy makers, journalists, scientists, universities and social debate. It is generally accepted, that companies also play an important role in addressing the challenges of sustainable development. In this role, making a key challenge to balance often conflicting pressures caused by sustainable development, that is, the level of corporate economic performance against environmental deterioration and social disruption. Effective integration of sustainability principles into companies requires action beyond the borders of organizations. The issue of sustainability is becoming more and more prominent in corporate governance. One of the most important area of supply chain management is for companies to gain a competitive edge in the market. This has a significant impact on the natural environment, and there is a growing need to integrate environmental thinking in supply chain management and processes, which is why companies are increasingly focusing on sustainable development, taking on more CSR initiatives and achieving a greener supply chain. Sustainable and green supply chain management practices have been developed over the past decades, trying to integrate environmental considerations into organizations by reducing unwanted negative consequences for the environment of production and consumption processes. In this article, I have examined the issues of sustainability and sustainable supply chain management, mainly based on descriptive secondary literature.

Technical Issues and Their Effect on the Financial and Time Scheduling of the Building Under Roof and/or Floor Upbuilding
324-343Views:110Building under roof and/or floor upbuilding raises technical issues different as one raise in the case of green investments. Primarily, depending of system of building constructions of the existing building there is a possibility to build under roof, and/or floor upbuilding. In the paper we review those technical issues, what decide, that in the case of given building there is or not possibility to build under roof, and/or floor upbuilding. We examine in general, that in the case of building under roof, and/or floor upbuilding what building process should be considered, and what kind of time and financial scheduling is advisable to prescribe. We will present a case study, that the inadequate processing of technical issues may require time and financial rescheduling.
