    202

    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.

The empirical research took place in the University of Debrecen, the most populouses University of Hungary, 6 month before the official opening ceremony of the Championships.

  • Laboratory investigation of the rediffusion of contaminants originated from the aquiclude

    Many organic pollutants are released into the soil and thus into the groundwater due to anthropogenic effects (a chain of harmful human activities). Layers with low permeability (e.g. clay) play an important role in blocking the path of these contamintants. However, due to their sorption and diffusion properties, such aquiclude layers can also serve as long-term sources of contamination. Once the layer is contaminated, it is already very difficult to recultivate, and there is a potential for the pollutant to spread to higher permeability layers by slow diffusion processes. This phenomenon is defined as a so-called rediffusion process, in which contaminants are retransferred from the aquiclude to the layer with higher permeability. The purpose of this study is to demonstrate the possibility of modeling this rediffusion process in a laboratory scale and to quantify the effect of influencing parameters on pollutant transport.

    Life cycle costs are important factors in decisions on renewable energy investments. Since maintenance costs generally constitute a high portion of the life cycle costs, the maintenance strategy applied in a project can affect the bottom line significantly. The effective maintenance tools used in the production industry (e.g., diagnostics, condition monitoring, data management, integrated information systems, machine learning, and automated decision making) can be involved in planning and maintenance of renewable energy systems to gain the benefits of these approaches. In this paper the effects of maintenance strategies on life cycle costs are investigated and the benefits of up-to-date condition monitoring techniques are presented through case studies.

    Vehicle dynamics models can be classified into two groups based on the model simplification. There are simplified models based on neglections, these models do not contain all body directions: longitudinal, lateral and vertical directions. There are several reasons for the simplification: control, estimation and analysis methods can be used only with simplified models, or another reason is the computational cost. Apart from simplified models, there are detailed/truth vehicle dynamics models which aim is to provide a virtual plant of the real vehicle for virtual prototype-based development. In this paper, some simplified vehicle models are presented, after a short introduction.

    Research and studies done on floorbal is usually associated with medical studies, however the research and analisys of other fields peakd little interest.Thus, the aim of the study was to present the situation of floorball in Hungary and to examine the opinion of passive sports consumers about the sport. Within this we deal with the competition system of our country and the organizational structure of the federation. In our primary research, from a viewer perspective, we were interviewed as passive consumers in a questionnaire survey about their relationship to floorball. In the questionnaire we discussed whether they had ever met this sport and whether they had seen it or what attracted them to the match. We also tested their willingness to pay. The results were compared with the opinion of one of the domestic leaders of the sport, which in many cases agreed with the results. The questionnaire was completed by 153 people, more than 95% of whom had heard of the sport and most had the opportunity to become familiar with floorball at primary school. 65% of those surveyed have already seen a live floorball match that they have mostly played with friends / acquaintances. This young sport can become more and more popular among young people, not only as a complementary sport.

    Both international and domestic research on passive sport consumption focuses on the motivations of fans. However in Hungary, unlike the examples of North America and Western Europe, we have to look for answers to the question of why people do not go to football matches. In order to find an answer to this question, we conducted an online survey with a number of items of 347 people. For the latter a scale measuring absence from sport consumption was used and the reliability of the scales was tested by Cronbach's alpha calculation. After our principal component analysis, we developed 5 internal and 5 external factors, on which we conduct hypothesis test along demographic and sports consumption variables. Based on our results, we have established that, contrary to public opinion, the low number of spectators in Hungarian football matches is not only and primarily due to unsucces and the low quality of matches. Our respondents are mostly kept away from stadiums by football-related government measures, as well as by preferring to participate in other recreational program opportunities.

    Danube is the main river of Hungary. Danube and its floodplains and oxbow lakes are operating as ecological corridors, although their industrial, logistic and touristic role is not negligible. It is well known, that from the source to the estuary of the river Danube there are many industrial facilities. This heavy industrial pollution had effected on the water quality. The most dangerous components of the sewage water of these facilities are heavy metals, which can be found in the water as well as in the sediment. These toxic elements can cause significant health risks, because they can accumulate in the food-chain. The main aim of our research is to investigate the accumulation rate of the heavy metal content of the river sediment in the different parts of the test plants. The main sampling place of our research was a sediment dump was created by excavation from the Open Beach of Dunaújváros in 2009. During our measurements we analysed the cadmium, nickel, lead, chromium, copper and zinc concentration of the sediment and the plants. The test plants, which are growing on this sampling place, were parella (Rumex patientia), perennial rye-grass (Lolium perenne), sedge (Carex riparia), bistort (Persicaria maculosa). The extraction of the heavy metal content of the samples was made according to the MSZ Hungarian standard. The concentration of heavy metals were analysed with AAS (atom absorption spectrometer). According to our results we determined that parella could accumulate cadmium, nickel, chromium and zinc in its upper stem, on the other hand bistort could accumulate these elements mainly in its leaves. These information will be important in the case of the in-situ remediation of a polluted area in the future.

    The importance of e-commerce in Hungary is unquestionable. 66% of the population is regular internet users (I3), every fourth person uses it on a daily basis. Online sales have increased from 137 billion HUF in 2010 to 427 billion HUF in 2016, while offline sales were not able to reach this growth (I1). Undoubtedly, online sale has become a very valuable market. The age group really valuable as consumers spends about 6 hours a day online, out of which 3 hours are active usage (I2). The Internet is also the most important source of information and keeping in contact, as 41% of the population uses it method. The availability of the Internet in Hungary is literally independent of the geographic location, thanks to the Digital Renewal Action Plan in Hungary's current strategy, as one of its main chapters is "Enhanced and Secure Infrastructure for All." (Botos 2013) plan. There are many unfavorable processes in Hungary's rural areas. Of these, emigration and the abandonment of the local economy are outstanding. To stop these processes, the "National Rural Strategy" (2012-2020) was created. Its most important areas are employment growth, balanced and diverse land and forest management, production structure, restoration of local food production and food markets, local energy production, strengthening the local communities, improvement of population patterns and conservation of natural systems and the biodiversity. The integration of rural economies into the on-line marketplace and their linkage to different DBEs not only vertically but horizontally can be one of the keys to their survival and development. The situation of businesses on the on-line marketplace in the countryside is very special. On the one hand, they are more favourable in many aspects of their operation, but in some cases they have disadvantages that fundamentally threaten their survival. The purpose of this article is to get to know this environment, map its benefits and drawbacks. For this, we use the results of in-depth interviews conducted with businesses operating on an on-line market in rural settlements.

    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.

    In the world of runaway, “homo-sitting” and mobile telephones, the quality of leisure time is gaining increasing importance, most of which is the experience gained and the characteristics of existing natural factors. A variety of thematic and adventure parks are reported every year, increasing travel and visitors' growth every year, the service offering of which broadly satisfies the needs of modern man and kind. In the focus of our research, we set the link between recreational habits and motivation of adventure park visiting. Use the survey questionnaire to calibrate consumer habits (n = 408). There were significant differences in the number of factors studied, such as those who seek more physical activities in their free time and prefer to respond to the challenge and extravagance motivating motivation in each of the adventure parks, or even for leisure-time enthusiasts. Our research reveals that service providers should consider targeting their leisure time habits, for example, they can benefit from a thorough consumer mapping from the point of view of electoral motivation.

    Eliminating losses is a daily challenge for both: companies and individuals in society. Whether through the production or office work, we are wasting the most important human needs: time and energy with useless things and processes. Both are an integral part of our daily lives and are particularly important for agricultural companies. In our study, we look at the relationship between Lean and agricultural companies. We outline the risks associated with these seven Lean Losses at these companies, and how these problems can be corrected and eliminated using current methods. Our research sheds light on how technological innovations affect and influence the position of companies in the market and in financial and human resources. We examine the benefits and drawbacks of the innovations applied and the Lean processes used, and how they affect the environment around them.

    In our research we pretreated synthetically produced greywaters with filtration on various filters, then we treated the samples with oxidative agents. We characterised the quality of greywater samples with several parameters. We investigated these parameters on the untreated, pretreated, and oxidated samples as well. We evaluated the efficiency of the treatments by measuring the characteristic parameters. In addition, we investigated the changes on the filter media’ surface with a scanning electron microscope (SEM). It was shown, that the most effective treatment combination for the greywater’s preparation for reuse is the filtration on silica sand or activated charcoal and silica sand combined filter media, then oxidation with hydrogen peroxide (10 mmol/dm3).
