Analysis of Thermal Degradation in the Annealing Process of Colored Parts Built by Extrusion-Based 3D Printing
124-133Views:393With the ever-increasing request of light materials, poly lactic (acid) PLA, have got much in consideration. Low-cost PLA materials have risen its use. Those possess some benefits but nevertheless insufficient mechanical strength. The printed PLA objects have a stumbling block for practical applications. Thus, annealing is an interested alternative to make 3D printed objects strong. This thermal treatment can significantly develop investigational studies and offer technical data. Hence the purpose of this paper is study and discuss how to increase the flexural strength through annealing process. Geometry distortions and color degradation will be analyzed. Differential Scanning Calorimetry, Taguchi Method (TM) and variance (ANOVA) were applied as part of the design experiments and analysis. Twenty-seven printed specimens were tested and factors as temperature, time and color were selected.

Development of engineering and innovation skills
364-369Views:157Spatial 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 solving mathematics problems, using mathematical models in practice, imagining a spatial figure and therefore to solve the spatial geometry exercises, so development of these abilities is very important. We have developed special tools and worksheets for development of engineering and innovation skills.

Maintenance Strategies and Life Cycle Costs of Renewable Energy Systems
106-116Views:141Life 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.

The Challenges of the Labour Law and Economic in the Future Labour Market
116-130Views:774The aim of the study is to examine how the effects of globalization affect the global labor market, and how high-level automation and digitalization affect the expectations of labor market actors and the world of labor law. We analyze the legal framework and the economic and social utility of acquiring competences for new challenges in the industry. We will look in more detail at the future of the low-skilled labor force in a changing labor market as a function of acquiring new competencies. We believe that changes in the labor market and novel processes will also pose new challenges for employers and employees. Changes in the labor market raise the question of what kind of benefits an outgoing worker will receive until he or she acquires new competencies. Is the social welfare system in the current sense capable of supporting lifelong learning, or is it necessary to explore alternatives such as basic income? All this needs to be done in the light of the legal and economic scrutiny of the concepts of efficiency and economy. This is because acquiring competences for the new employee also brings new added value.

Study on Mathematical Competence and Attitude of Engineering Students
43-55Views:220Efficiency of the learning process is in the focus of studies dealing with the Hungarian higher education, including engineering education. The efficiency can be evaluated if the required competences are declared and systematically controlled. In this paper the results of a graduate student survey is presented. Students taking part in the survey have got a bachelor's degree in engineering and are first semester students presently in different engineering master programs. Mathematical thinking ability and creativity, as important competences in studying mathematics were measured with the questionnaire, rather than formulas and complicated calculation methods. Students’ experience in studying and applying Mathematics were asked in the first part of the questionnaire.

Application of Team Coaching Tools for University Education – Case Study
445-456Views:496In 2010 the innovative Finnish higher education system (Tiimiakatemia – Team Academy) was launched at University of Debrecen Faculty of Economics and Business, which was also awarded by OECD and has been run at JAMK University of Applied Sciences in Jyvaskyla since 1993. In this system, we create team entrepreneurs who have to work together in teams. In this research the authors would like to look at how we can use the team coaching tools as a part of this model in our team entrepreneur education system to build high performing teams. Tuckman named five stages of team formation: forming, storming, norming, performing and adjourning. A new team cannot be expected to perform as an excellent team when it first comes together. It takes time forming a team, and they often go through recognizable stages as they change from being a collection of strangers to a united group with common goals. You have to understand it at first, than you can help your team become effective more quickly. Authors of this study work as team coaches in Team Academy Debrecen. In the last 6 years we have worked with several teams and experienced how group dynamics present at the teams and change through the learning process. We have faced with great storming period at different teams and managed to build high performing entrepreneur teams as well. Our experiences are introduced as case studies, after analysing, consequences will be concluded. As in the EFQM model we can find that to survive in the global competitive markets companies need the best teams for the best results.

The presence of stress and leisure sports in the life of today’s people
74-86Views:597Today's people are extremely busy with a lot of things, such as work, family, learning, so they try to spend their free time with activities that promote them in relaxation, reassurance, recreation. It can be said that the people of today's world are burdened, more stressed and nervous, trying to do the best they can to live properly. A lot of people have a hard time communicating, community life. There are a lot of people who are forced to work from home, as projects and weeks' deadlines don't wait. Besides, there are many things to be done, children need to be dealt with, you have to have fun, you have to pay attention to health, you have to run a household, etc., so there is little time for people to do what they really love. In my research, I assessed the leisure habits of the inhabitants of Romania and Hungary, but their attitude to active reclamation activities (N=273) was their activity in sport. The results show that passive leisure activities (watching TV, reading, listening to music, internet) are still the most popular among people, although most of us do sedentary work. People who play sports in their spare time felt more refreshed, and they had a better mood, more positive. The sports that people can play outdoors and in parks come to the fore.
