    Green infrastructure measures improves the quality of surface and subsurface waters along with increasing the water balance on the town level. The aim of the study is to estimate the potential runoff quality improvement by applying stormwater BMP-s along traffic roads in the town. This is of high priority in the aquifer protection area where runoff water may infiltrate into the aquifer carrying pollutants from the surface. Estimations are applied: first we determine the surface of traffic roads, then estimate the quantity of different kinds of pollutants accumulated on the surface and thirdly we estimate the expected performance of the applied green infrastructure elements based on findings in the literature. We determine the impervious urban surface area associated with transport-related functions within the protected drinking water recharge area using GIS technic using orthophotos. We estimate the expected reduction of runoff pollution assuming that stormwater BMP-s are applied in the area. The overall goal is to make the significance of diffuse pollution more obvious and enhance drinking water protection through taking diffuse pollution into consideration.

    The purpose of the paper is to analyze on micro level the stream of building materials needed for raising cattle. The scope of the produced material flow chart will cover the inflow and storage of the materials. The overall objective of material flow analysis is to contribute to the data inventory development process which is needed to use these construction materials as secondary raw materials in the future. The assessment is based on a concrete new development in a Hungarian region being carried out nowadays as a development and modernization of an existing cattle raising farm. Driven by the concern of resource depletion, further research on higher level, based on larger database will be needed to verify the estimated national level results for the magnitude of growth of anthropogenic stocks.

  • How Does Public Debt Change when the Next Crisis Comes - and It Will Come!/the Expected Evolution of Greece's State Debt in the Next Crisis Period/

    It has recently been announced that Greece may withdraw from the Euro-Zone permanent rescue fund's aid program because it has successfully met the conditions imposed on it. Creditors and credit qualifiers also agreed that the Greek economy was on a good growth path. That is why there is a chance that by 2030 the current sovereign gross debt of 182.7 per cent of GDP will fall to 123.3 per cent. The author finds this statement unfoundedly optimistic. He argues that the Greek debt ratio – despite the current optimum economic fundamentals – does not seem to be sustainable. He sees greater probability that in the near future it will again be necessary to release some of the Greek debt. Debt reduction will also mean a new orderly state bankruptcy. The study seeks to highlight how vulnerable and risked the sustainability of current Greek debt financing. Using a macroeconomic model, it shows and justifies how the Greek sovereign debt changes in the case of a crisis that is only half the extent of the previous subprime crisis. If this happens, by 2023, the state debt will rise to more than double the national product, and by 2030 only to the present, otherwise critical, level. It follows that the high risk of financing Greek state debt remains unchanged.

    Based on the model of the Deloitte Football Money League we recreated the „Hungarian Football Money League”, which gathers and analyses the most economically powerful Hungarian football enterprises. The model gave us an oppurtunity to analyse and compare the industry to the international level. With the hungarian professional football-enterprises we assume, the most economically powerful teams play in the NB. I. (National Championship). Because of this reason we only analysed NB 1. club teams. From the 12 participating team we selected only those 9 who stayed in the League for three consecutive years. The implications from this study is that the hungarian club teams stays well below the international level, altought top level enterprises' joint economical impact is indeed significant in the hungarian sportsector.

    When we discuss the topic of civic organizations, especially sports profile civic organizations we need to note and comment that issue how these organizational forms are able and capable to accept subsidies. The related data of the Central Statistical Office (KSH) highlight the phenomenon that incomes of the classic civic organizations are mainly composed of state or private source donations. Although there is a really and pretty predictable subsidy system in the field of civic sphere currently, from one hand the distribution of the single subsidy forms considerably vary, on the other hand it result in the considerable amount of available financial resources. The fact whether subsidy forms and subsidy incomes have relationship with the addition alvariables of the organizational operation, such as subsidies provided, employment relationship, and expenditures may acquire special attention at the management of organizational operation together with the planned strategic interventions in the field of the civic sphere.

    The European Union has enacted strict safety regulations on the usage of chemical substances. Not long ago the Hungarian Government has also enacted the 1907/2006/EK (REACH) regulation and 1272/2008/EK (CLP) regulation. With the acceptance of the decrees our knowledge and available information about chemicals has expanded, due to the reporting obligation. As a consequence the usage of hazardous chemical compounds will be safer for the people and the environment. With the access to the shared data, we will be able to make appropriate decisions despite lacking previous measurements of our own. My goal is to present the hazardous information profiles form the packages of the REACH and CLP, and their possible applications.

    The purpose of the current study is to give comparable results to previous and further examinations concerning the quality of household generated greywater and to determine the effectiveness of a household wastewater treatment system treating only household generated greywater. Data for this study were collected from a household which avoids the production of black water at the source by using dry toilet. Water samples were collected from January 2017 until May 2017, altogether seven times. Samples were taken from 3 different places: (i) potable water from the kitchen tap, (ii) greywater sample from the first sewage tank of the household sewage treatment system and (iii) greywater sample from the fourth (last) sewage tank of the household sewage treatment system. A total of 16 physical, chemical and microbiological parameters were measured in the laboratory using the valid standard methods in each cases. The results of this investigation show that separating black water from greywater at the source by using dry toilet may produce considerably smaller environmental load. Lower emission values stems from the lower organic matter, nitrogen and phosphorus content of greywater.

    In 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.

    The improvement of the project management forced the industrial organizations to focus on using the project management techniques in their industry, to plan and control the workflow to achieve their targets, further to increase the satisfaction of their customers. One of the most common project management tools are used is the work breakdown structure (WBS), which provide a framework for the implementation of the project scope including project planning, scheduling, monitoring, control, and estimation. Depending on the top-down approach the project activities will be broken into smaller parts that can be measured and controlled during the project implementation. The well-defined construction of the structure contributes to making the project more realistic and visual. However, the misunderstanding of the project WBS among the project team creates deflection and misinterpretation of the project scope. The main issue of this research is to improve the WBS of the installation plan and develop a standard WBS for plant installation. The research was limited to Asphalt plant installation WBS as a case study to identify the weaknesses of the current WBS at the case company which leads to extra installation time and cost. The research is offering a template WBS based on the company logic, defining the frequent risks that affect the plant installation based on the WBS and suggesting a suitable response strategy by recommending a control framework to monitor and control the WBS schedule throughout all installation phases.

    The lean approach is based on the buyer, while eliminating losses, in addition to value creation and efficiency gains, it determines the direction of developments in the process. To successfully build and maintain lean, engagement and development is indispensable, but it is not as simple as changing past behaviors and attitudes. The company also realized that changes were needed, as the increased number of employees in the company, and the increase in production and the profits associated with it, made it clear that organizational development is needed. The organization development was started by SWOT analysis, and along with Ishikawa's assay, I discovered whether LEAN was necessary for the company. With Gemba, I took a look at the problems and then categorized them to designate development points.

    Nowadays, the research of rural areas’ specific features is one of the most interesting part of sociology. Within these studies the rural areas ability for survival and to retain forms an important basis. A pillar of these, that the youth from rural areas become sufficiently motivated to stay at or to return to their homeland and be able to redound development. We were looking for answers, that how university students, who participated in our current research are thinking about the hungarian countryside, in their opinion what are it’s advantages and disadvantages and it’s possible potentials. In addition, we examined those factors, which are contributing to that respondents who are studying in large cities want to stay there, but at the same time we wanted to explore the opposite factors, those that make tudents to return to the countryside. Last, but not least we investigated a very interesting topic, the relations between the respondents and the rural elite.

    The subject of our research was the examination of the sports ambition and its motivational background. Our aim was to examine the volunteer experience of young adults in volunteering. Our goal was also to analyze the areas in which sports are chosen most voluntarily and what motivates them in sport. The basis for our questionnaire research was the concept of volunteering "4 W" (who, what, where, why). The questionnaire was designed to answer these questions in relation to sports ambition. The data of the questionnaire completed by 371 young adults (mean age = 23.93, sd = 9.93) were analyzed using SPSS statistical software, where we calculated basic statistics (mean, standard deviation, median, mode) and Chi2 test. More than 75% of the respondents have already worked as volunteers. One of the most popular areas of volunteering was sport. The most frequented volunteering area was among schoolchildren and students as well as university sports among young people, after which the area of competition and recreational sports proved to be the most popular. The main motivation of young volunteer workers was the following, : „I had a good mood”, „I loved sport”, „teamwork”, „work experience”, „learning and skill development” and „career perspective”. Organizations, marketing and communication areas in the field of sporting events and sportsclubs volunteering were the most popular in the area where the respondents had experience. A significant difference was found in the field of organizing and marketing volunteering in sports events, 61% of Hungarians worked, while respondents from other countries were only 34.2% (p <0.05). In the field of communication, higher values of respondents from other countries (45.7%), compared with Hungarians (33.7%) (p <0.05).

    Faster attacks, spin speed, increased adrenaline levels, vehement play. This is all about the 3X3 basketball. In Debrecen, the first 3X3 basketball matches were held in 2015, most of them did not even think that the sport would be popular in Hungary as well. Practically, from the start of the first minute, the games were played with great success. Following the successful settlement, the International Basketball Association immediately offered a 3-year contract to Debrecen. The purpose of our research was to examine the 3X3 basketball tournaments in Debrecen, which was analyzed using a questionnaire and an in-depth interview. 69% of the respondents participated in the 2016 and 2017 events, but only 37% attended the 3X3 basketball tournaments that were held for the first time in 2015. It can be stated that this trend is growing and the event is gaining popularity nationwide. Sponsors and sponsors covered every issue of the event so the event was free of charge over the years. 72% of fillers, however, are willing to spend money on a possible entry fee. In terms of revenue growth, the introduction of admission fees is unlikely to reduce interest. Up to 1200 seats have been filled up for the event every year. Therefore, it is not surprising that a lot of people would like to enjoy a higher auditorium with more space. The introduction of 4-point boundaries (3 points) for 3X3 matches would be a great opportunity to try the "little brother" of basketball in the 4-point so that it can be introduced in traditional basketball. Hungary became the pioneer of the sport due to the results of the Hungarian national team and the successful organization of sporting events.

    In industry, service and public sector lean approach is gaining ground. However, there is a significant difference between the organizations applying lean concept in case of their lean transformation maturity level as well as their lessons learned. There is a huge variety of methods and techniques which can be used but there are two conditions in case of every organization regardless their sector or their lean maturity level which determine the success of their lean development: lean approach leader and learning organization. Lean leadership is not based on a particular sector or method and a ready-made lean organization is not needed either. The concept of the top management has a huge effect on the characteristics of theorganization but whether the will of the management is enough for the complete transformation or not is the question. Is the target the lean organization itself or how a unit of an organization or the whole organization can react to the change of the environment? The attitudes and behaviors of lean approach leadership can be applied every day, everywhere and support the aim of creating a real lean organization.

    With the introduction of latest tools and the expansion of technological solutions, the usage of smartphones ,with instant internet connection of course, has become an essential part of the net generation, also known as generation Z. At the same time, the role of IoT devices has also become part of our daily lives, completing and sometimes making it easier. This is due to the fact that the tools become more and more cheaper as time passes and parents and young people no longer consider these a technical innovations, but as a necessity. These generations; Y, Z and Alpha appear simultaneously on today's job market, which poses a serious challenge to future HR leaders and recruiters. Because of the generational gap between them, both motivational and demanding, novel solutions are becoming increasingly appreciated in this area as well. The purpose of this study is to demonstrate the potential of gamification and to highlight the its major areas, as well as to draw the attention to "good practices" in creative recruiting through better known examples. In addition, I also tried to point out the effect on the relationship between motivation and flow-experience. The gamification method is becoming more and more popular in our country, as it plays an increasingly important role in business and education as well. In recent years, with the use of serious games, there have been several examples of HR recruitment and selection, which clearly strives to reach out to younger generations.

  • Forces Attributed to Dark Matter May Originate from Entangled Particles as Seen in the Shape Of Galaxies Formed by Grbs

    Recently, it has been suggested that entangled particles may be connected by a wormhole. If that is right, what is the distance between them we have to take into account when applying Newton's law of universal gravitation to these particles? We propose the idea that these particles may attract each other regardless of distance, resulting in a force that behaves exactly the same way as the force derived from presumed dark matter. Traces of such a force seem to be present in galaxies due to gamma ray bursts (GRBs) that produce entangled particles which hit various objects. We can observe that in barred spiral galaxies the arms always pass through the nucleus of the galaxy so we believe that the very first GRB happened at the central supermassive black hole (SMBH) and the arms are the traces of this ancient GRB. If we see an unbarred spiral galaxy, we can be certain that the arms do not pass through the core and we think the very first GRB happened close to the core. Ring galaxies may also be considered as a type of spiral galaxies, since there is a section where the ring is broken, i.e. where the arms do not meet. So the very first GRB happened far from the core. Elliptical galaxies may have resulted from an ancient GRB which hit from outside. The arms rotating in opposite directions of the NGC4622 galaxy support our hypothesis. Finally in the silk threads of the spider web of the universe, the traces of GRBs can be seen.

    The utilization of renewable energy sources spread with stormy speed on the world therefore more and more municipalities propose that they satisfy their energy demand from renewable sources. The fossil fuels represent a significant proportion in Hungarian energy balance and the majority of these is import energy. The proportion of renewable energy sources must be increased to decrease the energy dependence and the energy cost of municipalities, to increase the energy security and to consider the aspects of environment.The interest of Hungary is to increase the proportion of renewable energy sources in energy supply. In order  to this, the government created the small-scale household power plant (SSHPP) category in the Electricity law. This power plants should be not greater than 50 kW's performance. In this category, electricity can be produced from renewable and fossil sources. Since the government introduced the small, household size power plant category the installed capacity was grown quickly in the last seven years. The general capacity was 0.51 MW altogether at the end of year 2008 but it has already approached 129 MW’s at the end of year 2015. The general capacity was increased by the multiple of the previous year every year between 2008 and 2015 and there will be more a dynamic capacity expansion. Data about the capacity and the produced electricity can be displayed on municipality level, too. The purpose of the investigations is to determine: how can the built capacity of the small, household size power plant category participates in the electricity supply of the Hungarian settlements? So how many percentages of electricity demand can be gratified by this electricity power on the settlements? Based on this a ranking can be made among municipalities which shows the level of sufficiency in production of renewable energy and give a possibility for the power shift.

    Spatial visualization skills have an important role in teaching and learning of engineering studies. Many studies have shown that there are correlations between various measures of spatial skills and performance in particular Science, Technology, Engineering and Mathematics (STEM). Many engineering students have problems with imagining a spatial figure and therefore to solve the spatial geometry exercises, so development of spatial ability is very important. We have developed special tools and worksheets for development of spatial abilities
