  In my study I have examined the sections of Hungarian contemporary architecture and fine arts. In the historical overview it has become clear that two turning points have influenced contemporary arts: the total art work (Gesamtkunstwerk) of the Ghotic and Baroque styles. I listed the sections in three categories: metamorphosis, relationship and section. The sections are the highest level of these categories. I explained my research in detail by analyzing these sections, at János Megyik's art and his Gate statue at Life Science building and library at the University of Debrecen.

  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.

  Globalization and the recent explosive development of technology have significantly changed people’s lifestyles resulting in an increase in the number of people living a sedentary lifestyle. COVID-19 pandemic has exacerbated the situation and created an unprecedented situation in the world. In the present study, we investigate changes in the physical activity and sedentary behavior of adult workers caused by the coronavirus epidemic. In our online cross-sectional research, we used snowball methodology. The target group of the survey was adult workers. 108 people filled in the questionnaire, the majority (73.1%) are women, the average age is 37.18 years and most of them have higher degrees (Diploma: 74%, PhD: 14%). The present study revealed a decrease in physical activity and an increase in sedentary time for the employees in our study. Despite respondents detected a decrease in their physical activity, an increase was reported in the proportion of online training participants. The majority of respondents partially, or totally switched to work from home during the pandemic, which may further increase their sedentary lifestyle. We did not find significant differences among the domain of work and leisure time or occupational physical activity patterns. The workplace is a great opportunity for promoting physical activity and reducing sedentary time in the adult working population, therefore it would be important for organizations, decision-makers and health professionals to work on the design of strategies to these goals.

  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.

  A residual dross of high quantity and high salt content arises from the hot (thermo-mechanical) treatment of the primary dross generated by the production of aluminium alloys from scrap. It contains a relatively low concentration of metal (5 – 10 %) but a high amount (30 - %) of chloride salts and some other components beside the oxide matrix. Due to the components dissolved in or reacted with water, this industrial residue - arising in thousands of tons also in Hungary – qualifies as hazardous and causes a real burden to the environment. According to the laboratory experiments aimed at an economical technology, the chlorides are dissolved within a few minutes when a liquid/solid ratio of 1:1 cm3/g (water volume:sample mass) is assured with an intensity of the horizontal shaking to prevent sedimentation. However, the filling ratio of the vessel also appears to have an effect. An implementation of relatively low cost would allow the recycling of the salt and the application of the final residue for alternative purposes.

  For agriculture, precision farming means the future by increasing incomes and reducing environmental loads at the same time Precision management produces a surplus in yield, revenue, result, but not immediately. The additional income potential is expected to increase by 20% to 50%. Farms mostly introduce precision farming in order to relieve workers. However, many farmers are afraid of the use of new technologies, but the use of information technology in agriculture will be unavoidable. Technology is fundamentally expensive, not even widespread, and farmers use only a few technology elements. Moreover, following the precautionary principle technology used in farming covers only a part of their agricultural land. So farms need to learn to produce more precisely than before in a knowledge-based manner.

  Az ellátási lánc teljesítményét nagymértékben befolyásolja a szereplők készleteinek összetétele, nagysága, rendelkezésre állása. A végső fogyasztókért vívott versenyben kiemelt szerepe van a kiszolgálási színvonalnak, hiszen az ellátási láncok ugyanazokért a fogyasztókért vívnak versenyt, és a fogyasztók döntése leginkább e két tényező, mint a készlet nagyága és a kiszolgálás minőségétől függ. A tanulmány a kkv-k logisztikai problémáit feltáró kutatás része, melynek célja rávilágítani a jellemző nehézségekre, és azokra a kihívásokra, amelyek legtöbbször elkerülik a logisztikai- vagy ellátási lánc vezetők figyelmét. A fejlődő kkv méretű vállalkozások versenyképessége - ami magába foglalja a költségek nagyságát is, kapcsolódva a K+F tevékenységhez vagy vállalat növekedéshez – a lekötött tőke mértékével arányosan változhat, melynek jelentős részét képezik a készletek. A kutatásban résztvevő vállalat, a Diego Kereskedelmi Kft. készletezési politikáján keresztül kerül elemzésre a készletek összetétele, illetve a velük kapcsolatos kockázatok, illetve félreértések. A tanulmány célja továbbá a helyes megoldások elősegítése, melyhez szorosan kapcsolódik (az itt tárgyalásra nem kerülő) Lean megoldások támogató szerepe.

  The industry value of the global platform economy exceeded 7 trillion US dollars by the end of the second decade of the 21st century. The income generated by the platform economy in the European Union produced an almost five-fold increase in the period between 2016-2020, as its volume increased from 3 billion euros to 14 billion euros. Nevertheless, due to the lack of global consensus and precedent, the delimitation of the platform business model and work, its legal regulation and verifiability and compliance, due to its innovative nature, are unresolved at the world and European level. The objective of the article is to define the conditions, rules and practical application of the platform economy and platform work, relying on international (English-language, mostly European) secondary information, thereby revealing the problems and difficulties, as well as discussing its advantages and disadvantages.

  In this study, we have dealt with the calculation methods of the eigenfrequencies associated with the bending vibrations of rectangular-shaped beams clamped at both ends. Said eigenfrequencies were determined analytically in the single-degree of freedom model of the beam and the case of the three-dimensional solid and three-dimensional rod models by finite element modal vibration analysis. We presented the calculation method of the characteristics of the analytical model and then calculated the eigenfrequency for a concrete example. We have described the concept of modal characteristics, and in the following, we have determined its natural frequency based on the solid-beam and rod models of the former beam. We calculated and compared the solutions belonging to the models recorded in different ways in 11 additional cases of the presented methods.

  Nowadays sensor networks and other systems, based on the IoT concept demonstrate the benefits of their usage, which includes the support of the decision-making process, therefore achieving an optimal result in the context of more and more fields. In this experiment, an additional sensor network has been developed based on a modular system derived from a previous development by means of a target-specific modification of the required modules to measure environmental data in a drying chamber used in food industry. The main objectives include the development of the device, the verification of the measurements of the factory-built device, providing an interface, which is able access the measurement data and after gathering experience from the usage, further developing the system and extending the functionality of the web application. The built-in data acquisition and control system stores the data of the measurements in the form of text files, while our additional data acquisition and control system uses a unified measurement database to store the data. According to the structure, a task-specific application has been developed in order to unify the two sources. Analysis of collected data was performed after running the ETL (extract, transform, load) algorithm converting the transaction-oriented database. The experiment shows so far the benefits of the multi-point measurements by a significant difference between the measured values, so we certainly consider further developments.

  The methodological basis of research on networks is given by graph theory. During the network analysis we work with a big data population and we are mainly analysing the relationships of the actors, which can be visualized with the graph network. The analysis of social network is becoming more and more popular in academic life as well. Most of the co-authorship networks are built around a number of prestigious people who manage their own network as a central player creating cliques.

  Over the last few years, companies have realised the significance of the image they represent and besides building the brands of their products, they started to concentrate on forming the brand of the company.We wanted to examine the world of corporate brands at two FMCG (fast moving consumer goods) companies. The aim of there search was to discover the connection between consumers and brands, product brands and corporate brands; how corporate brand influences customers during purchased ecision making. The effect of consumers’ knowledge was also observed about the companies on consumers’ habits. We have assumed that from the viewpoint of some customers, choosing among several products is often based on the perception of the brands and products alone and it has little to do with the corporate brand. Although, if one of the companies has a strong corporate brand, an idea built around it, and its message is communicated effectively, when it comes down topic king sides, the brand of the company could be essential to decision making.

  The pyrolysis is a promising process for producing syngas from wastes. However, the by-product of the technology may contain large quantities of carbon, therefore it is suitable for further syngas production. In this paper we examined the steam gasification of brown coal from Felsőnyárád and char from RDF pyrolysis derived from an experimental pilot plant operating in Zalaegerszeg. We performed our experiments in a laboratory-scale fix-bed reactor at 900 °C. The aim of this work to examine the efficiency of syngas production from pyrolysis char, as well as to explore the similarities and differences of the thermal decomposition of the feedstock materials.

  Today, the number of people who use public transport is decreasing, while the share of private transport is growing steadily. In order for people to choose public transport instead of a more convenient and more flexible individual transport, we need to know the factors that can influence them most in their decisions. In the first part of our article we review the main features of intermodality, intermodal nodes and intermodal public transport. Intermodal integration has to be realized through physical, network, fare, information and institutional level. In order to be able to formulate the integration goals correctly and to operate the entire intermodal system efficiently, we need to know the preferences that most affect the decisions of users of public transport or of nonusers. According to the literature, comfort, prices and travel time, on which people judge the status of public transport.

  In today's global economy, there is a substantial shift from manufacturing to services, which challenges both economic policymakers, business stakeholders, owners, suppliers, competitors, and ordinary people: restructuring will encourage all economic players to learn how to adapt to new trends. That is why our research focuses on innovation and the ability of companies to create value. The IT sector is currently one of the fastest-growing and most innovative sectors within the service industry. The success of IT companies is greatly determined by their ability, how to make effective use of their intangible assets at their disposal, including intellectual capital, which is defined as a non-financial asset. So the question may arise: how is it possible to quantify and in monetary terms the intellectual capital of the companies to be examined? That is why, we calculated for the most successful Hungarian IT companies the widely recognized index, the VAICTM index, for which domestic calculations are not yet available. Indeed, this indicator eliminates the lack of information stemming from reporting standards by the methodology relying on publicly available financial reporting data. The indicator itself is a top indicator whose two main sub-indicators quantify the effectiveness of intellectual capital and physical capital.

  Nowadays we are struggling with many environmental issues that require up-to-date environmental specialists. Amongst the causes of environmental problems, long-standing industrial companies are dominant, for which, on the one hand, the assessment and elimination of existing environmental damage and prevention can be the goal. Universities would be able to provide the necessary knowledge and skills with appropriate educational and research programs. In the research we carried out a comprehensive study of environmental engineering education programs of Hungarian higher education institutions. We analysed the strengths, weaknesses, opportunities and threats of the various educational programs. In addition, on the basis of the analysis we made suggestions on the possible directions of the development of the environmental engineering training.

  Our study analyses the connection between perceived and ideal organizational cultures and academic results. A modified, self-managed OCAI questionnaire was used to measure perceived and ideal organizational cultures among engineering management students of the University of Debrecen Faculty of Engineering (N = 114). Our results reveal weak positive linear correlations between academic performance and perceived or ideal level of clan culture. In case of other culture types we did not find any consistent relationship. Based on our results students who consider clan culture ideal can expect better results than those who prefer other types. Among students who visit at least 61% of the classes those who reported fitting (or better fitting) perceived and ideal cultures tend to perform better in their studies.
