    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.

    This paper aim is to review the implementation of artificial intelligence (AI) in the Human Resources Management (HRM) recruitment processes. A systematic review was adopted in which academic papers, magazine articles as well as high rated websites with related fields were checked. The findings of this study should contribute to the general understanding of the impact of AI on the HRM recruitment process. It was impossible to track and cover all topics related to the subject. However, the research methodology used seems to be reasonable and acceptable as it covers a good number of articles which are related to the core subject area. The results and findings were almost clear that using AI is advantages in the area of recruitment as technology can serve best in this area. Moreover, time, efforts, and boring daily tasks are transformed to be computerized which makes a good space for humans to focus on more important subjects related to boosting performance and development. Acquiring automation and cognitive insights as well as cognitive engagement in the recruitment process would make it possible for systems to work similarly to the human brain in terms of data analysis and the ability to build an effective systematic engagement to process the data in an unbiased, efficient and fast way.

    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.

    Many countries are making considerable efforts to achieve solutions to environmental problems that we face today and developing renewable energy resources is one of the potential long-term solutions that constitute an absolute priority from a sustainable development perspective. The usage of renewable energy is one of the critical future challenges to reduce greenhouse gas emission and decrease energy dependency at the same time. Thus, replacing traditional energy sources with renewable ones, like Hydropower and wind power to produce electricity instead of fossil fuel. The objective of this study is to find a relationship between renewable energy consumption, macroeconomic factors, and the environment. There is a reliable and significant (at 1% significant level) association between REC with GHG and GDP and a relatively strong association with EC.

  • Mechanical Design and Finite element Analysis for Acetabular cup

    Hip replacements typically consist of a four-part piece. Our research will focus primarily on the acetabular component. Several different types of materials can be used when creating a hip replacement implant ranging from plastic to titanium. Different materials are used to accommodate for allergic reactions or circumventing potential health risks. Aside from the material, the size of the components plays a factor in terms of durability; a larger diameter head might avoid dislodgement though it could increase wear and tear on the stems through constant friction. A patient’s force applied to the hip replacement is usually measured through a number of physical assessments. Finite element analysis (FEA), a computer-based method of data observation, allows for us to accurately simulate hip forces and their impact on the hip replacements. Through this, it becomes easier to predict and calculate the performance of specific designs. Generative systems can also be used to support performance analysis and optimization through assessing a multitude of cases, many of which apply in real-world scenarios. By applying both systems, we designed and modeled an acetabular cup that when measured decreased the mass from 129 grams initially down to 52 grams, a 60% decrease in total mass. Furthermore, the design we created lessened the trauma on the piece through distributing force across the entirety of the piece rather than specific segments only. This shows an increased durability and life expectancy when compared to usual acetabular cups.

    Thanks to technological advances and environmental standards, as well as changing usage patterns, road vehicles are constantly developing. Electric and hybrid vehicles are playing an increasingly important role in today’s road transport. The most significant changes are probably in the powertrain of vehicles. The efficiency of internal combustion engines increases while their emissions continue to decline. In addition, high performance electric motors, batteries and even fuel cells play an increasingly important role in hybrid and electric vehicles. In this publication, we review the drive systems of current modern vehicles and the types and characteristics of their major components. We also review the available models and computer programs for their simulation, focusing mainly on MATLAB/Simulink applications. Based on this, we can develop our own models and simulation programs which will help us to perform different driving dynamics simulations and to compare the performance, dynamic and energetic characteristics of these powertrains and their components to each other.

    Digitalization and the explosive development of technology have led to significant changes in football. Due to the increasing amount of data available through various sensors and other data collections, we can observe the rise of data-centric, analytical and statistically oriented thinking in football, which is also of interest to fans. Digitalisation is also closely linked to sports consumption, which is why we have seen significant changes in this area in recent years. The pandemic has further amplified the speed of digital transformation in the sports industry. One of the most important contents for sports organizations and their fans is the in-depth sports statistics and analysis that enhances the consumer experience. In our study, we examined the most common performance indicator in football, passing. Our goal was to examine the position-specific pass characteristics in detail, therefore we also examined different pass properties in our research. As a model for our analysis, I chose the premier league, which has the highest UEFA coefficient. The three rounds (rounds 30-32) of the championship season 2019/2020 have been recorded and analyzed in terms of passes. there was a significant difference between the average number of passes per game between defensive and offensive players (t=7,988, p<0.05). There is also a gradual decrease in the number of passes attempted per match and the accuracy of the pass in the examination of the middle positions when examining the positions in the depth of the pitch. For both pass accuracy and average pass count, the decreasing ranking corresponds to the position of positions on the pitch (order: 1, central defender 2, defensive midfielder 3, inside midfielder 4, attacking midfielder 5, striker). In the value indicator of the position for passes, offensive positions performed more effectively than defensive positions. The extreme positions also stand out among the attacking positions, where in the case of the position value per pass number, 23.3% of the total test was completed and 14% of the amount of the established position value indicators was provided by these posts. Overall, our study points to post-specific pass characteristics and, knowing this, we can state that the comparison of players' passing performance is relevant if the players are in the same or related positions.

    The impact of macroeconomic factors offers insight into the performance of an economy. This study investigates the dynamic short- and long-term effect of trade openness, external debt, and foreign direct investment (FDI) within Ghana's economy. Utilizing Autoregressive Distributed Lag (ARDL) bound testing and Granger causality analysis, the study examines data spanning from 1991 to 2022. The results of the ARDL cointegration test reveal a long-term relationship among the variables. However, in the short term, the findings present a mixed effect of FDI and trade openness, with both positive and negative impacts. In the long run, FDI and external debt exhibit a positive influence, whereas trade openness appears to impede economic growth. Furthermore, the Granger causality test identifies a unidirectional causality relationship between the variables and economic growth. The study suggests that the government implement investment-oriented and trade policies to stimulate economic growth.

    Food security is a fundamental but often neglected aspect of economic growth and sustainable development. This paper examines the effect of food security on productivity (GDP/capita) over time, while taking the income level of various countries into account. Dynamic panel regression analyses suggest that food security is positively related to productivity, but this effect is stronger in more developed countries. The study highlights the complexity of the economic problems faced by the least developed countries, where increasing the consumption and supply of food is insufficient for significantly increasing economic performance.

    The support system of renewable energy production was changed in Hungary in 2017. The legislator created the Mandatory Purchase (KÁT) system earlier to encourage the electricity production from renewable energy sources and waste. The Renewable Energy Subsidy System (Metár) changed the Mandatory Purchase (KÁT) system from the 1st of January in 2017. It had been known before Metár came into force that the supported period in the Matár would be only 13 years while it was 25 years in the KÁT. Therefore, a real rush started for the KÁT support licenses in 2016 in order to make more beneficial contracts by the investors. At the time, the Hungarian Energy and Public Utility Regulatory Authority (MEKH) released a record amount of licenses (more than 2000 pieces) to build solar power plants under 500 kW performance. This is more than 1000 MW total power. This paper searches the answer how this solar power plants will influence the level of self-sufficiency of the Hungarian settlements in the electricity supply if those are realized. Hereinafter, we will analyze the possible impact of these solar power plants in the settlement electricity self-sufficiency.

    The study aims to define global career and to present an applicable method. Internationalisation and globalisation indisputably have affect on companies actions. The value of human capital as a resource has got notably higher than before. To retain competitiveness, multinational companies have to focus their sight on employees with globally usable knowledge. In today’s globalized world international assignments are particularly frequent. It is a must to differentiate between working abroad willingly or sent abroad by the company. Achieved and applied knowledge from international assignments are essential ingredients of global career. However, the inappropriately planned career structure can cause damage for the company and for the cost effectiveness of the HR department. It is vital to appoint the most suitable employee for the assignment, to increase the company’s success rate and to maximize the individual’s performance as soon as possible. The effectiveness of the selection has influence on performing a successful assignment in the process of the career path.

    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. Finally, to what extent can be built upon this power plant category in order to that Hungary can comply its objective value.

    Nowadays, we can observe an increasing trend in the spread of non-communicable diseases. It is important to highlight the social factors that negatively affect health. Determinants includes income, education and the research-relevant working and living conditions. From a labor market perspective, unemployment and poor working conditions are a significant responsibility for the deterioration of mental and physical health. Health is also affected by employment conditions. Extended working hours have been shown to be harmful to health. Poor health has generates poorer work performance, a higher rate of sick leave, and higher health care costs. My primary goals in my research was to explore the labor market impacts of workplace health promotion and guidelines for corporate health promotion. Within health promotion, physical activity has played a prominent role. I’ve been used secondary data collection during my research. I have been performed a traditional literature analysis based on domestic and international studies. My results are suggest that the workplace health promotion has more positive labor market effects than increasing productivity and reducing absenteeism and health care costs. It is important to mention that health promotion could bring benefits to both employers and employees. Regarding corporate guidelines, there is no new approach directive other than the older literature sources. thus, it may be worthwhile to develop a new and different corporate process for effective workplace health promotion.

    We can observe more and more often that people change their jobs frequently. They work for more employers during their life. The question may arise that organizations should care about the career management of their workers? Certain surveys which investigate the reasons of job changes can disprove it. One of the most common causes is that employees cannot see their career opportunities at the company. The organizations should not necessarily use complex career development systems it may also be appropriate, if they use only some techniques consciously. The study shows the career management tools used by the organizations examined in the survey. The authors demonstrate that there is a provable relation between organizational performance and career development methods. Furthermore they describethe techniques applied by the successful organizations.

    Organizational culture and Leadership both have been under research for a long time, as they play a vital role in the performance of an organization. The organizational culture is the set of rules or acts as a guidebook of an organization for achieving the objectives while leadership defines these rules and implements them as well. Organizational culture is dependent to a great extent on the norms and values of the society or the country where it is located. Important for achieving the objectives of an organization, this factor plays a vital role while setting the organizational culture. Incorporating organizational culture and then sustaining it is done by the leaders. Leadership if does not play an effective role in regards to implementation of the organizational culture, can collapse the organizational structure. Leaders are required to develop the qualities according to the organizational culture and should be responsible to come forward to transform if necessary and implement the system. The organizational culture should fulfill the needs of the organization’s goals and the norms of the society. Both leadership and organizational culture are co-dependent on each other and should be understood together.

    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.

  • Introduction to Design and Analysis of Torsional Vibration Dampers in Vehicle Industry

    The crankshaft of today’s internal combustion engines with high performance output are exposed to harmful torsional oscillations originated from the unbalanced gas and inertial forces. To avoid the fatigue damage of engine components, caused by the undesired vibrations, torsional vibration dampers can be applied. Viscodampers are one type of the torsional vibration dampers, which operational fluid is silicone oil. For cost-effective R&D activities and production, finite element and finite volume numerical discretization methods based calculation techniques must be involved into the engineering work supported by the modern computer technology. The aim of this paper is to provide an insight into the multidisciplinary design and development process of visco-dampers in vehicle industry applications. Four different examples as structural, fatigue, CFD analyses and structural optimization have been introduced in the present work. It turned out from the static structural and fatigue analyses, that the investigated damper has safety factor over the limit for both static structural and fatigue analyses, so it is suitable for the given load conditions. In the structural optimization process 34.36% mass reduction has been achieved. According to the coupled fluid dynamic and heat transfer simulations a rather stagnating air zone evolved between the engine and the damper during the operation, which can cause efficiency reduction of cooling fins mounted onto the housing. In light of the numerical results, the suitable damper position has been determined for the highest heat transfer.

    Analyzing the information available in the Hungarian database of the CSO, we can see that a significant part of the income of classical non-governmental organizations, especially non-governmental organizations with a sports profile, comes mainly from state or private support. In addition, it can be said that these organizations are essentially non-profit-oriented and play a significant role in social integration and the performance of essential social tasks. Therefore, the relevant question is to what extent and in what way their social embeddedness is realized, in what way do NGOs influence people in the course of their operation? Within this, the study of the social usefulness of sports non-governmental organizations and the sphere of support conditions in the sphere emerges as a priority area. In our study, we undertake to examine the activity of the organizations included in the survey, their social impact and to compare the results with their role in local society. Nearly 50% of the NGOs surveyed in the study have a local scope, and more than 50% typically engage in grassroots and leisure-related activities.

    Today, more and more articles have emerged in the field of sustainability and sustainable development. Sustainability plays an important role in supply chain management too. Green Supply Chain Management (GSCM) has emerged as a key approach for enterprises seeking to make their businesses environmentally sustainable. The notion of GSCM implies the insertion of environmental criteria within the decision-making context of the traditional supply chain management. Enterprises are increasingly expected to extend their sustainability efforts beyond their own operations to their suppliers and customers to their sustainability expectations. Literature of green supplier evaluation and selection methods number is large, though the number of environmental factors are relatively limited. Recently in supply chain management decision making, approaches for evaluating green supplier performance have used both qualitative and quantitative environmental data. Given this evolving research area, the purpose of this article is to analyse research conducted in international scientific journals focusing on the selection and evaluation of a green supplier. The purpose of this article will answered two questions: Which selection methods are commonly used? What environmental and other selection criteria for green supplier management are popular?
