Mechanical Testing of 3D Metal Printed Stainless Steel Specimens
7-13.Views:298Additive manufacturing (AM) is a cutting-edge production method, which has come a long way since its first introduction in the ’80s. Back in the days its usage was very limited to stereolithography, and was only able to make weak structures, so it only worked for visualization. Four decades later it is one of the leading research fields in production areas, because of its flexibility and its ability to make almost any complex geometry. However, no matter how powerful it is, it is not omnipotent, there are certain size and shape restrictions even this method must apply to.

Vállalkozói képzés a 21. században a felsőoktatásban – lehetőségek, módszerek, jó gyakorlatok
1-18Views:664Challenges of the 21st century require answers from higher education as well. In Europe, most of the entrepreneurship programmes on the higher education institutions are less than ten years old. Whilst business studies may battle for academic legitimacy, it has a clear advantage when it comes to graduate employability. The aim of this paper is to give answer to the following questions: why entrepreneurship education is important, what are the methods which are already used and what are the results of them. The answers to the questions are based on literature reviews, a case study and in-depth interviews with alumni carried out at the University of Debrecen, where since 2010 Team Academy Debrecen, a new education model from Finland is implemented. Tiimiakatemia education is an innovative Finnish model founded in 1993 by Johannes Partanen that develops team entrepreneurs. Based on the results some of the important elements of entrepreneurship teachability are: learning by doing, passion, learning in teams, coaching and mentoring.

Laboratory Testing of Rediffusion of Contaminants Using DKS-Permeameter
41-48Views:270Decades long hydrocarbon contaminations effecting heterogenous groundwater systems is a common problem both in Hungary and worldwide. Only the treatment of aquifer layers is possible with remediation technologies, so the contaminations remained in the aquitards are released back to the treated porous layer after the treatment due to the changes in concentration-gradient. This process is the so-called back-diffusion: as a result, the previously removed contaminations appear in the remediated layer again. In order to get better understanding of the rediffusion process and the influencing parameters series of measurements were carried out at the University of Miskolc Faculty of Earth Science and Engineering using a special laboratory device called DKS-permeameter. With the help of some small modifications it can be used for the modeling of backdiffusion. Artificially contaminated soil samples were built in the DKS-permeameter from which contaminanant release occured due to back-diffusion. The concentration values were determined with spectrophotometric measurements.

Microbiological and Chemical Investigation of Drinking Water Samples on the Operational Area of Pannon Víz Zrt.
151-160Views:349In our research the potable water quality was monitored between 1 January 2015 and 31 October 2017 in the operational area of Pannon-Víz Zrt. The connection between temperature, microbiological load and chemical parameters were investigated. After evaluating data, the following results have been identified. The seasonal changes of the microbiologically positive samples are determined by the contamination caused by Escherichia coli, Enterococci and Pseudomonas aeruginosa. The coliform group and the 22°C and 37°C colony-form units showed no seasonal dynamics. The analysed chemical parameters were below the limit during the examined period. Based on the correlation analysis, there is no correlation between chemical and microbiological parameters.

Industry 4.0 Concept and Key Elements
100-111Views:463Growing and constantly changing international competition, increasing market volatility and demand for increasingly customised products (personalised manufacturing), and shorter product life cycles create significant challenges for companies that traditional production systems can no longer meet. Industry 4.0 is a new manufacturing paradigm focused on creating intelligent products and processes. The focus has been placed on achieving fully effective customised production under conditions suitable for mass production. Make-to-order replaces make-to-stock. Despite the growing interest in Industry 4.0, it is still not a consensual concept. There is no clear idea about this new manufacturing paradigm, so I attempt to present the available definitions of Industry 4.0 through the presentation of the scientific literature, declare the concept's technical elements, and present them in detail to get a clearer picture of the concept.

The Relationship Between Sports Civic Organizations and Human Resources
146-154Views:347Every spring the Hungarian Central Statistical Office records through its ELEKTRA database system the human and economic related operation data of the past year of civic organizations. This data source is usually considered as a standard at the evaluation of the domestic civic sphere. Still, the available handout titled “Most important features of the non-profit sector”, applying mainly descriptive statistics only provides a brief picture of specifications of the sector. Parallel with it, its background database is available yearly, which provides a unique possibility for a researcher to perform secondary analysis aiming to reveal deeper relationship. The objective of our study is purely to reveal a minor part of this considerable field, the relationship between subsidies and human resources mainly due to the fact, that human resource in this sector is composed of employees and volunteers, and it is questionable whether subsidies have an impact on employment. Results revealed that there is a relationship between human resources and subsidies, where mainly private nature subsidies have a strong impact equally on voluntariness and work related employment

Numerical analysis of effects of an open-pit coal mine to groundwater
70-74Views:299In this study we investigated the hydrogeological problems of an open-pit brown coal mine in the Borsod coal basin with Processing Modflow software. The coal mine is located in the valley of the Sajó-river with high transmissivity overburden layer where the traditional dewatering solutions were not encouraging due to inrush risks and low cost-efficiency. A new way of barrier forming was found out and numerically simulated to prove the efficiency of the solution. Since there are several contaminated sites in the surroundings it was a key factor to assure that the new mine dewatering technique has only a negligible effect on the groundwater regime that undisturbs the known contaminant plumes nearby.

A bankvezetési kultúra változása a gazdasági válság hatására
261-273Views:285A 2008/11-es globális gazdasági válság eredetét az elemzők jellemzően az amerikai másodrendű jelzálogpiaci válságra vezetik vissza. A gazdasági válság bizalmi válságba ment át, mely időben elhúzódást, hatásában pedig mélyülést jelentett. Összesített hatásként a pénzügyi szektor a valaha volt legmélyebb válságát élte át, melynek következményeként a tradicionális hatalmi viszonyok is megváltoztak. Hosszú idő után a bankok szabályozásáért és felügyeletéért felelős politikai vezetők globálisan vissza tudták venni a primátusi hatalmat a pénzügyi/gazdasági vezetőktől. A primátusi szerep elvesztése, a válság kitörésében játszott szerep, a társadalmi felelősség, a bankmentő akciók következményei, a reputáció csökkenése, a bizalomhiány mind közrejátszottak abban, hogy a bankvezetők és a banktulajdonosok új vezetési és gazdálkodási kihívásokkal találják magukat szemben. A tanulmány erre a nemzetközi és hazai kihíváshalmazra keresi a kulturális válaszokat.

Application of Heutagogical Methods in Entrepreneurship Education
364-373Views:287According to Kuit and Fell (2010) the educators’ task is to develop the learners’ lifelong learning skills to be able to apply their skills and competences in and efficient and creative way in new situations in a constantly changing environment. Kamenetz (2010) argues that neither the pedagogical nor the andragogical teaching methods are suitable for performing well in their job, but more and more a self-directed and self-determined approach is needed in which the learner reflects on what and how he learned, and the educator teaches the learner how to teach himself. The concept of heutagogy provides such principles and practices which can give an answer for the above-mentioned challenges in higher education. The authors examined how the heutagogical methods can be adapted at entrepreneurial courses and how the students evaluated these courses.

Consumer Perception of Electric Cars in Hungary – Theoretical Considerations and Empirical Results
1-23Views:1032Electric 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.

Sportcivil szervezetek – számok a támogatások növekedése mögött
126-134Views:349A KSH adatgyűjtési tevékenységének köszönhetően a nonprofit szervezetekre vonatkozó átfogó adatok mind adatbázis, mind tájékoztató formájában elérhetőek. A gazdasági adatok között feltűnik az az évről-évre hasonló nagyságú, domináns támogatási részesedés. Különös tekintettel a klasszikus civil szervezetekre ez egyértelműen jelzi azt, hogy a szféra támogatáskitett és támogatásfüggő. Ezek a szervezetek ugyanis kimondottan alkalmasak támogatások fogadására. Tanulmányunkban szeretnénk másodelemzés révén rávilágítani arra, hogy a sporttal foglalkozó civil szervezetek/sportcivil szervezetek száma milyen összefüggésben van a támogatásokkal, különös tekintettel két specifikus támogatási formára, a NEA-ra és a TAO-ra vonatkozóan. Az eredmények arra utalnak, hogy van összefüggés a támogatások összegének növekedése és a sportcivil szervezetek számbeli növekedése között, és ez kifejezetten igaz az egyik legrégebbi és legújabb támogatási forma esetében is.
