  In today's changing world, it is extremely important that organizations can keep up with market trends. The perspectives of continuous development are expanding and the commitment of decision-makers to development activities is growing steadily. The starting point for organizational development is always man. Organizational development always begins with deeper research and modeling. Fundamental guidelines are set out as a paradigm of development. The most important and at the same time the most difficult step is to introduce the results of the analysis. The most effective, but the most time-consuming and cost-effective solution is full organizational development. The management of the organization faces significant efforts to embark on a full organizational development process. The aim of our study is to propose different development opportunities for the company's management with the help of analysis by the organization and supported by measurable data, as well as the catalyst for the modifying efforts observed among employees.

  Nowadays the term of management is so popular. It has an essential role in the professional life, moreover in the every day life too. Creating and using the quality indicators (one of the qualiy management tools) contribute to the improvement of the operation of the healthcare system and to the development of the quality of healthcare services. The aim of the paper is to define service quality and its dimensions in healthcare and to highlight the role of quality indicators. The research calls attention to the absence of indicators measuring the different aspects of quality directly, the difficulties of measuring service quality and the need of establishment of more specific measures in healthcare. A special area of healthcare, there habilitation of musculo skeletal diseases will be discussed. As a research my approach is to define all the indicators that are already used in this area of the healthcare. This examination is extremely important because one of the most commonailments are the musculo skeletal diseases and their number is just increasing.The paper is mostly descriptiv and follows analitical methods based on the international and Hungarian professional studies, informations. To access databases I was helped by the OSAP (National Statistical Data CollectionProgramme). Besides the importance of quality indicators the research calls for the need for more specific measures. On the other hand, the value of the paper lies in collecting the problems, defaults and improving areas of a specific healthcare field.

  The reason behind is that they have their own principles, strategic goals and industrial environment that they have to manage on daily bases. The current labour and talent shortage across Europe forces local companies to supply their demand of manpower from foreign countries – encouraged by the ’four freedoms’ of the EU. In consequence of the globalisation, we have to keep in mind that running a talent management system has its challenges. For instance, employees with different cultural background might have unconventional needs. Due to the cultural, demographical and economical differencies, we must know the structure of our labour force to use the most beneficial tools to induct, motivate or retain our human resource. The aim of this research is to analyze Europe’s and China’s talent management systems to reveal similarities and differencies between them and pick the most notable ones. From the point of comparison, analysing China would be important for European countries to discover further possibilities, as nowadays China has one of the most dynamically developing economy with enormous population behind. The primary result of the research is that deficiency of talent is irrespective of the size of the population and it causes difficulty in both European and Chinese fields, therefore it proves to be a real and general challenge needing attention at organizational level. Furthermore, identifying regional patterns considering peculiarities, the framework of talent management systems can be defined and be found summarised in the article.

  The importance of working while studying in higher education has a globally growing tendency, and Hungary is not an exception. The demand for the opportunities of student employment has been recognized not only by the students but also by the policy makers of higher education, leading to the introduction of solutions like the obligatory internship semesters or the dual training programs. The current study contributes to the better understanding of this field through the analysis of a database from a questionnaire survey conducted among bachelor students from seven majors of the University of Debrecen during the Fall semester in 2015 (N = 589). The main findings suggest that the students mostly consider the internships as an investment into their future career while the short term compensation and the personal interests have a lower importance for them. About 75% of the students would be willing to work not more than 20 hours a week, and most of them would look for ‘official’ studentwork. For working, they would sacrifice the time connected to the following activity-areas (relative to the other activities in the list, and in descending order): time for leisure (this is the most likely to be sacrificed), for sport, for friends, for family, and for learning (this is the less likely to be traded in for working hours). Willingness to work (measured in daily working hours) seems to be connected to the following factors: major, year of study, how important the activity areas are considered compared to working (learning, family, friends, sports, leisure), and the importance of finding a personally interesting internship.

  In recent years, the global use of contingent workers is rapidly increasing despite the increasing quantity of artificial intelligence applications in business. The question is "how these companies leverage the use of artificial intelligence to enhance contingent workforce's management?". The ideal goal of this paper is to develop a purely conceptual application of innovation, artificial intelligence (AI) adjacent to contingent workforce management(CWM). The researcher used qualitative information gathered from various authors and observations to reinforce the usage of AI. One of the critical tools to integrate with contingent workforce management for reduction of time spent on human resource administrative tasks is AI. There must be a transformation of thinking, accepting positive organizational change, utilization of technology and openness to new technology to foster  AI. Along with that, integrating contingent workforce management with AI reduces risks and costs, increases efficiency and quality of work. Innovation and Artificial intelligence have been used in five pillars performance of contingent workforce management to mitigate the challenges associated with it.

  The Dunning-Kruger effect (DKE) in higher education evaluation is one of the current research areas of psychology, educational science, and management science (in our case). Its importance is that the less prepared one is, the less accurately one can judge what performance is expected of him. What is more, he will err more and will overestimate himself. The present study aims better to understand the phenomenon with new, small-sample empirical results. The study is part of a research series that has been ongoing at the University of Debrecen since 2015. It not only quantitatively expands the literature but also includes the course of Knowledge Management among those examined. During the research, students were asked both before the examination (N = 63) and after the examination (N = 76) to guess how many points they would achieve on a multiple-choice test. It supports the presence of DKE, both in the case of pre-examination and post-examination self-evaluations. Using four multivariate linear regression models, we examined whether the sign value or absolute value of the errors made during the guesses show a correlation - in addition to the available control variables - with the test score. Our results showed that the more accurate the pre-examination and post-examination estimations were, the higher the students' actual score was, while the less they tended to overestimate their preparation. This supports the presence of DKE, both in the case of pre-exam and post-exam self-evaluation.

  The impact of technological advancements on the labor market and innovation processes is a critically important research area. The aim of this study is to examine the emergence and frequency of technological innovations in scientific publications, with a particular focus on the Journal of Labour Economics from 2000 to 2020. The research employs content analysis methods, searching for eight different terms and expressions related to technological development (e.g., technology, artificial intelligence, machine learning) across 1405 articles. The study also analyzes the number of occurrences and annual publication trends of these terms. A total of 9469 instances were identified, indicating that in 64,7% of the cases, at least one technological term appeared. An analysis of annual trends reveals an increase in the usage of certain keywords (technology, artificial intelligence, and machine learning). In a smaller subset of articles, only 1%, technological terms were mentioned at least 50 times. The results suggest that although the topic of technological development plays a significant role in labor market research, the frequency of its appearance and the depth of analysis vary considerably. The increase in the appearance of technological terms is predominantly observed in the fields of artificial intelligence and machine learning. These findings are specific to a single journal, indicating the need for further research involving other labor market journals to ensure representativeness.

  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.

The main objective is the evaluation of the effectiveness of the program through some of the HR functions. This study contains the process of the selection and the evaluation of getting into the program. What makes the program special, is the appearance of the technical mentor. According to the hypothesis, the mentor’s assistance reduces the uncertainty when the trainee inducted into the organization. The occasions of the beginner education, the conversations and feedbacks during the induction adds more efficiency to the success of the program. The searched data in literature features HR functions and mentoring. To learn about the program, a case study was made beforehand, and then the questionnaire was edited for the trainees at the company. In the course of the research, an interview was done with the technical mentor. The interview was based on the questionnaire. In point of the results, recommendations were defined connected to the assumed shortages of the program, also to increase the efficiency of the selection and induction. In conclusion, the maintenance of the trainee program is equally beneficial for the trainees and for the company as well.

  Nowadays, the fourth industrial revolution is taking place at an incredible speed, with innovation at its heart. Of this, R & D funding is of paramount importance, which is directly or indirectly one of the most important tools for increasing corporate competitiveness. The study examines trends in domestic R & D expenditures over the past one and a half decades. It focuses on the extent to which the financial crisis has affected the amount of funding resources and their structure. From an international comparison, Hungary and the European Union spend much less on research and development than those in the global competition. The impact of the crisis is reflected in the decline in the growth dynamics of R & D expenditures, but it has not been solved solely as a result of the crisis. Changes in the domestic structure of expenditures in recent years are encouraging and are in sync with the change in attitude that is considered desirable in R & D funding. If we examine the domestic statistical data more thoroughly, we can no longer be very satisfied. However, from trends in data from recent years, it becomes apparent that neither Hungary nor the European Union will achieve the 1.8 and 3.0 per cent of GDP R & D spending by 2020.

  The companies’ most important goal is the satisfaction of consumers’ needs and the profitmaking. But nowadays the companies have to deal with the activity of corporate social responsibility, too. Therefore it can be interesting to research about the next questions: can ethics be taught? Do we have to teach ethics in the schools and especially in the business schools? What are the students’ attitudes toward the social responsibility? Are students sensitive and open-minded connection with this issues? The aims of the study were to examine responsible management attitudes among business students at the University of Debrecen (Faculty of Economics and Business). We draw their CSR pyramid (based on Carroll model) and present their opinion in reference to business education’s role in social issues.

  In a globalised and accelerated economy, managers are under increasing pressure to reconcile organisational goals that are independent from human being with the reality of human relationships. The human being, as a being with intellect and senses striving towards happiness, is the focus of positive leadership styles and is their major concern in the field of management theory. In this article, three such positive styles, authentic, servant and ethical leadership principles and their operating conditions are compared using international literature. The literature time span of about two decades shows that the evolution of the ethical leadership literature has slowed down, while the authentic and servant leadership literature has continued to evolve and is still evolving today. The comparative table that appears in this study highlights both commonalities and distinctions, in that, in addition to high moral and ethical standards, the authentic style focuses primarily on the person of the leader, the ethical leader on the ethical standards of the organisation, while the servant leader focuses on the development of the well-being of the subordinate, the other person, even through self-sacrifice.  We intend to use the results of this research to investigate measures of positive styles, preparing the scientific ground for future primary empirical field studies.

  The measures to improve energy efficiency and increase of renewable energy production and consumption should be encouraged in the interest of sustainable development. Many factors can influence the use of renewable energy such as the level of economic development of an economy, nationals’ and the main  economic actors’ environmental awareness, energy import dependency, ratio of the urban population, and government subsidization intensity among the others. The main purpose of this study is to examine the relationship between the share of renewable energy in the total energy consumption and net energy import as a percentage of energy use less production, greenhouse gas emission per capita and human capital using by OECD countries data from 1990 to 2014. The results indicate that there is a negative relationship between net energy import and renewable energy consumption, and also negative relationship can be shown between the amount of greenhouse gas emission per capita and renewable energy consumption. However, we identified a positive relationship between human capital and renewable energy consumption for energy importer countries above a certain level of human capital.

  Student evaluation of faculty members is a current topic both internationally and in Hungary, partly due to the massification and partly due to the marketization of higher education. One of the evaluation methods is the internet-based voluntary rating which was started by ratemyprofessors.com in the U.S.A. and whose Hungarian counterpart is markmyprofessor.com. Research studies on the U.S. website – among many other critics – established that reliability of this evaluation method highly depends on the frequency of ratings: if an individual tutor is evaluated by more students, then the standard deviation of the ratings is smaller. The previous conclusion about the U.S. website is tested in our study based on Hungarian data. Our main result is that many of the experiences about markmyprofessor.com echo the previous findings about ratemyprofessors.com. Beside this in the Hungarian sample the higher response rate is associated with lower average ratings.

  A 2016-os tanév őszi félévében tettem először kísérletet arra, hogy információt szerezzek az első éves mérnökhallgatók elképzeléseiről: a mérnöki szakmáról, a helyes mérnöki magatartásról, és a saját alkalmasságukkal kapcsolatban. Az első felmérésem a félév első óráján készült. A feltett kérdéseim arra irányultak, hogy kiderítsem, tisztában vannak-e az érettségi után a műszaki felsőoktatásba bekerülő fiatalok azzal, hogy milyen szakmát választottak, milyen jellemvonások jellemzik a jó mérnököt, valamint hogyan látják önmagukat, megvannak-e bennük ezek a tulajdonságok. A második felmérés a féléves mérnöki etika tárgy oktatásának befejeződése után, tehát a félév végén készült. A kérdésekre adott válaszokból azt akartam megtudni, hogy mennyire segíti elő a mérnöki etika tárgy oktatása azt a nemes célt, hogy erkölcsös mérnökké váljanak a hallgatók. A következő évben egy új évfolyam esetén szintén hasznos mindezek tisztázása, ezért 2017 őszén újra elvégeztem ugyanezeket a felméréseket, és érdekes különbségekre bukkantam. Ebben a tanulmányban mutatom meg mindezt
