    The goal of this study is analyzed and design a methodology to reduce stem mass, through topology and lattice optimization of a Ti-6Al-4V hip implant, meeting yield stress requirements. Four optimization cases were studied: Topology optimization (1), Lattice design 100% (2), Lattice design 50% (3), Lattice design 25% (4). Five load cases from a study were applied for each optimization cases: Combined (LC1), standing-up (LC2), standing (LC3), going up stairs (LC4), jogging (LC5). The optimized cases design reduced stem mass approximately by 30% (1), 5% (2) ,8% (3) and 2% (4), compared with the total stem hip Ti-6Al-4V implant.

    The aim of the research is to do a statistical evaluation of agricultural and rural development engineer student’s motivation and personal competency. It sums up the late generation Y’s characteristics and challenges. To be a successful, graduated employee, not only the skill is needed but the personal competency as well. Altogether, 121 filled out questionnaires were collected from the students which were the prime source of the research. They had to evaluate influential factors to their motivation level and competence. The database was analyzed with descriptive statistic methods, principal component and cluster analysis. Studying the personal competency, five different factors were divided based on Belbin’s team roles and four clusters. The four clusters were established by the five factors. Analyzing the student’s educational motivation four different components were divided: the need of performance, social entertainment, the benefits of learning in the near future and the reach of the financial freedom. Based on the four components, generating clusters was not possible due to the significance level of the K-means cluster analysis because it was higher than 0,05 in every grouping variables.

  • Application of Heutagogical Methods in Entrepreneurship Education

    According 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.

    In the frame of the project EFOP-3.6.1-16-2016-00022 „Debrecen Venture Catapult Program" it was held an occasion among secondary school students the aim of which was formation of that concept which is very important in the engineering area. In many cases in order to solve problems necessary that students have an "ideal" function concept image (the image is interrelated with the notion of the concept) and they can change between different representations of the function. In our paper we will show the experiences of the occasion in which was formed the function concept by investigation of several relationships from the everyday life and engineering area with the help of individual and cooperative learning method.

    In our study, we undertake to explore the social background of fresh graduates (has absolutorium) by field of study. In doing so, we put great emphasis on the educational attainment of the parents and the financial situation of the family, as these factors can have a significant impact on young people's learning opportunities, attitudes and career paths. In the theoretical part of our research, we consider it important to present the experiences of domestic and international authors on the socio-economic situation. Subsequently, the 2015 Graduate Career Tracking System (DPR) database provided us an excellent opportunity to study the complex data collected by the 34 higher education institutions. In our analysis, we highlighted the different socio-economic backgrounds of graduates from different disciplines. Based on our research, we have concluded that young people from richer families are in a better position on the labor market, earning higher incomes than children of parents with lower social status

    Globalizálódó világunkban, ahol a KKV-k egyre inkább részeseivé vállnak a nemzetközi piaci versenynek, a klaszterek szerepe a cégek versenyképességének támogatásában meghatározó. Az elmúlt évtizedben jelentősen megnőtt az érdeklődés az innovációs klaszterek iránt, mely mögött részben az a felismerés húzódhat, hogy a vállalatok versenyelőnyét nem csupán a saját kompetenciái, erőforrásai jelentik, hanem a földrajzilag közeli üzleti környezetében fellelhetőek is. Ahhoz, hogy a klaszterek eredményesen tudjanak működni, bizonyos egyéni és szervezeti kompetenciákat birtokolnia kell. A hatékonyan működő klaszterekre tekinthetünk úgy, mint tanuló szervezet, hiszen az egyének törekednek képességeik folyamatos fejlesztésére, a közös tanulás képességének elsajátításában motiváltak, kollektív elképzelések, közös célkitűzésekés és azok megvalósítására való törekvés jellemzik. A tökéletes tanuló szervezet rendelkezik a folyamatos innováció teremtő képességgel, melyhez nagymértékben hozzásegíti a folyamatos tanulási folyamat, amely új tudást és magatartásváltozásokat eredményezve, hozzásegíti a környezeti változásokhoz való alkalmazkodását. A tanulási folyamatok esetében fontos szem előtt tartani, hogy legalább olyan ütemben tanuljuk, fejlődjünk, amit a környezeti változások megkívánnak. A készségek, képességek, a klaszterszintű együttműködés szempontjából azért töltenek be kiemelt szerepet, mert ha a partnerek nem rendelkeznek a kooperációhoz szükséges kompetenciákkal, akkor az együttműködés lehet bármennyire előnyös, az nem lesz eredményes, hiszen csak korlátozott működésre lesz képes. Miként segítheti elő a „Tanuló szervezet-ként” való viselkedés a klasztert, hogy a szükséges kompetenciákat megfelelő szinten birtokolja? A cikk vezérfonalát a klaszterek eredményes működéséhez szükséges kompetenciák beazonosítása, valamint a klasztereken belüli tudásmenedzselés, tudásmegosztás megvalósulásának vizsgálata adja.
