Relationship between the Lean and Agricultural Companies
370-381Views:337Eliminating losses is a daily challenge for both: companies and individuals in society. Whether through the production or office work, we are wasting the most important human needs: time and energy with useless things and processes. Both are an integral part of our daily lives and are particularly important for agricultural companies. In our study, we look at the relationship between Lean and agricultural companies. We outline the risks associated with these seven Lean Losses at these companies, and how these problems can be corrected and eliminated using current methods. Our research sheds light on how technological innovations affect and influence the position of companies in the market and in financial and human resources. We examine the benefits and drawbacks of the innovations applied and the Lean processes used, and how they affect the environment around them.

Experimental Study of Connections with Hardwood Studs
26-34Views:242Attitude change is needed in design of timber structures. Truss girder made of timber elements wi th small cross sections can be used on large spans. Constructing structures with the use of these prefabricated trusses reduces the need of in-site work, and makes the use of ti mber structures economic. Rods of truss can be connected with the use of hardwood stud. On this way all steel components can be eliminated from the truss, so it can be used in aggressive environment as well. Dowel type connection, with hard wood stud is the subject of the present research. Hardwood studs were investigated individually and also as the part of separated connections of the truss girder.

Segmenting the Impact of Organizational Structure and Leadership on Project Resilient and Project Success in the Ethiopian Construction Industry: a FIMIX-PLS & PLS-POS Approach
73-103Views:307This research looks at the vital roles of leadership and organisation design in the attainment of project resilience and success in the construction sector. Informed by contemporary theories on organisational resilience and leadership, a framework was developed and rigorously tested against data using Partial Least Squares Structural Equation Modelling (PLS-SEM) and with more advanced techniques of segmentation (FIMIX-PLS and PLS-POS) to identify and take into consideration unobserved heterogeneity. Using data collected from project professionals, resilient leadership and adaptive organisation design were shown to be critical to project resilience, but the effect of leadership and organisation design on project resilience differed from segment to segment as well as across demographics. The ex-post analysis suggested that the awareness of resilience, practical experience and higher education exacerbated the relationships between aspects of resilient leadership and project resilience, as well as between adaptive organisation design and project resilience. The analysis also showed that relationships between leadership, organisational structure, and resilience can be mediated by demographic factors, such as awareness, experience, and education. The findings highlighted the importance of fostering inclusive, participative type leadership styles and continuous forms of experiential learning to enhance resilience outcomes. The value of specific indicators such as team participation in decision making or the leader's self-confidence was also identified as being critical aspects of resilient organisational structures and effective leadership. The implications of this study were important for each group of stakeholders: organisations should encourage resilience-based leadership, experiment with multi-dimensional flexible team structures and create a culture of continued, experiential learning and communications as knowledge and industries evolve. The theoretical contributions that validated the effects of segments of latent variables and offered insight into the added value of using segmentation were positive contributions to theory. Limitations, such as sample size and sector, stimulate avenues for future work and in particular reinforce the case for longitudinal, cross-sector research to build sectors’ internal and external constructs of project resilience. Future research needs to apply multi-facilitated empirical, qualitative and advanced analytics means to enable further quantification, and complexity in project survival, success and resilience.

Requirements for Multicultural Competencies Defined by a Focus Group
44-56Views:361Globalization, the spread of multinational companies and the enormous development of information technology can lead to a new trend in employers’ requirements. However, being employed by an international company is a real possibility for any employee in any part of the world. Even if they do not have to work abroad, employees may have to function in a multinational environment in their home countries. A favourable combination of intercultural competencies is a key factor in the selection and development of employees. A possible way of measuring these competencies can be the Multicultural Personality Questionnaire (MPQ). First of all,on the employers’ part, it is important to clarify the exact requirements and competencies (dimensions) to be able to draw up an ‘ideal profile’. We prepared two versions of the MPQ (91-item; 5-dimensional) and used them to test employers’ requirements in the selection process regarding the dimensions of cultural empathy, open-mindedness, social initiative, emotional stability and flexibility. This study describes the results of a focus group interview, which took place in 2017, revealing the importance of multicultural competencies from the employers’ point of view and examining the conditions of the adaptability of the two questionnaires. We used the focus group method to find out in what conditions the questionnaires canbe used in a selection process. What possibilities and limits are therefor using the direct five-dimensional questionnaire? What aspects do we need to take into consideration in expressing and interpreting the requirements in the results of the test?

Analysis of Social Media Activities - Through the Examination of Handball Clubs Competing at Different Levels
39-53Views:611In Hungary, handball enjoys special attention and support, this is true not only for our country, but also for Europe, and the sport is gaining more and more space worldwide. One of the biggest innovations of the last two decades is certainly social media, which has reformed the basic strategies related to information transfer and traditional marketing activities. The processes of content production on these platforms have radically changed, which every sports club should pay attention to, as they can gain significant advantages in terms of economics, marketing and community building if they are able to communicate well. Three sports clubs competing at different levels were compared during a qualitative study in terms of their social media marketing strategy activities, namely PICK Szeged, Balatonfüredi KSE – BFKA Balatonfüred and DEAC handball team. The basic concept of this research model was built on how the online marketing communication activities of club teams fighting for different professional goals at different levels differ from each other, as well as what are the development opportunities and aspects that can be used as effectively as possible on social media platforms. The handball club teams agreed on several research questions, but a significant difference could also be discovered in one area, in which the professionals responsible for social media disagreed or represented a different point of view. Looking at my results, it can be concluded that behind a successful online marketing strategy there is always serious preparation and planning work, as well as the diversification of content production on different platforms, because the consumer communities of the platforms are also different from each other.

Performance Management Innovation is a Medium-Sized Enterprises of Light Industry/
1-9Views:403To achieve the strategic objectives of the management of a company, has to monitor and coordinate continuously the tasks of the employees, they have to do to reach the targets. In this action, sometimes the management of the company has to make corrections in the work and motivations of the employees. This article presents a case study carried out on a medium-sized companies working on the light industry field. It presents a new motivation system for the employees to increase up those products, for those who are at the bottom of the producing rankings of the company, moreover to develop their performance to reach the average level. Here has to be mentioned that, the employees at the bottom of the performance rankings producing under the average levelobligates totally the same amount of circulating and standing capita of the company, lead to the intervention of the management. The norm based requirements within the framework of the production system were completed to provide the more efficient working of the employees, besides strengthen their skills and their loyalties to their colleagues. As a result of the innovation of the performance management the product of the employees standing at he bottom of the rankings increased up considerably. It has manifested formerly in the decrease of the pointing error fixed to the personal monthly norm, moreover it showed the catching up of the employees standing at the bottom of the ranking to the middle. The case that the employees at the bottom get closer to the others in the middle of the ranking helped to contribute to achieve the strategic objectives of the management through reducing the average cost of the producing, since increasing the budget of the producing activities.

Effect of Heat Input on the Toughness Properties of S690QL Steel during Hardfacing
1-12Views:84In recent years, the use of high-strength steels in hardfacing process has become increasingly common. One typical industrial example is the case of hydraulic shears used in building demolition operations, where the components are exposed not only to significant abrasive wear but also to intense dynamic loading. The use of quenched and tempered high-strength steel grade S690QL has become particularly widespread in this field, primarily as the base material for the hardfacing applied to the most heavily loaded regions of demolition shears. However, quenched and tempered high-strength steels are highly sensitive to the effects of the welding thermal cycle, which typically cause detrimental changes in the microstructure and mechanical properties of the heat-affected zone. The thermal cycles occurring during hardfacing differ from those typical of fusion welding, and consequently, the structure and mechanical properties of the resulting heat-affected zone may also vary. In addition, the penetration depth of the hardface layer can differ, which may significantly alter the load-bearing cross-section of the high-strength steel and, thus, the in-service behavior of the component. In the experimental work, hardfaced samples were performed on S690QL base material using different levels of heat input, thereby producing varying penetration depths. The aim of the study was to determine the effect of penetration depth on the resistance of the hardfaced component to dynamic loading. The tests were carried out at both +20 °C and –40 °C. The results clearly demonstrated that samples with deeper penetration exhibited reduced toughness at both investigated temperatures.

Geothermal energy utilization in the Bükkalja region by reusing abandoned hydrocarbon wells
351-357Views:403Hungary is a country in an inactive volcanic area, but with a geothermal potentical recognized bot hat European and international level. The geothermal gradient of the country is ~ 45°C/km on avarage, while in other countries it is ~ 20-30 °C/km. Accordingly, the temperature can reach 55-60°C at 1 km and 100-130°C at depths of 2 km. There are many types of extraction and utilization of geothermal energy, of which a large group is energy recovery . This direction is not typical in Hungary, so it is worth developing. The developement of the sector is slow due to high initial invertment demand and the long planning phase. On the one hand, the aim of our reserach is to take steps to remedy this problem by examining the funcion change of a barren well. Int he foreground and peripheral areas of the Bükk Mountains, there are numerous unused hydrocarbon wells, which our work is examining for energy purposes with a view to their later utilization. The present study focuses on 13 abandoned wells in the Pünkösd Mountain, area of Bükkalja, Demjén.

The Evaluation of the Employment of Migrants by Employees
102-114Views:298The exploration of specifications of the employee groups endangered in the labour market, and their social
and labour market integration have always been a challenging task for the professionals. As a result of the
domestically also appeared migrant wave, the actuality of the topic has even more increased. In this study -
prepared in the framework of the research program „Human resource management challenges of the reception and labour market integration of the migrants” - we aimed to reveal the attitudes of employees about the labour market integration of the migrants. We have defined an objective to explore whether they are afraid of losing their current jobs, what factors influence the employment of the migrants and what kind of positive and negative effects they take on the society and economy. Based on the results of the survey we have found that employees are not afraid of migrants taking their jobs, still they are quite uncertain whether they would employ or work with a migrant person. Regarding the effect on the society and economy an unambiguous negative attitude was experienced. -
A Domestic Investigation of Online Banking
22-32Views:550Nowadays, the spread of digitalization is constantly increasing. The current rising generation is already a “digital native”. As part of digitalisation, mention should be made of the Internet, which has been given a prominent role in our daily lives. We search for information on the Internet, we communicate, we buy. Due to these factors and the pandemic in 2020, internet administration has become a priority. Banks need to constantly adapt to meet their needs, promoting convenient, home banking. In the course of our research, we focused on this continuous adaptation and the resulting improvements. The research focused on the Internet and mobile banks of large Hungarian banks. Sampling took place over 2 periods. Among the primary research tools, we chose document analysis, and netnography. In the research, we compared the functions available on the platforms, the consumer perception of mobile banks and other variables. Based on the results obtained during the research, it can be stated that domestic banks are constantly developing their application along different trends and trying to adapt to changing needs. Serious changes had to be made in the mobile banks of most large banks, even with the permanent elimination of their former mobile banks. Changes can have a strong impact on consumers, who are often more likely to have a negative view of them. Digitalisation is also particularly important in this sector. The study contains the details of the course work prepared for the Scientific Students’ Associations Conference.

The Relationship Between Sports Civic Organizations and Human Resources
146-154Views:343Every 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

Diagnostic Model for Supporting the Development of Health-conscious Organizational Behavior
1-18Views:475In the 21st century more and more countries of the world take the attitude that human health is not just an issue for healthcare services but for all major areas of life. Such an area for employees is the workplace. Protection of employee health and safety has for a long time been a non-transferable (objective) obligation and responsibility for employers in Europe. Connections between health and the workplace have however extended far beyond the traditional aspect of safety and health at work. Developing a health-conscious organisational behaviour means a challenge for many Hungarian companies; the model described in this study assists them in both diagnosing their current situation and choosing the appropriate course, method and tools for development.

Frequency Domain Analysis of Tractor Tyre Enveloping Properties
223-229Views:215Main source of vibration excitation for off-road vehicles are ground profile undulations. Most unprepared terrains are characterized by wavelength of unevenness that is of the order of magnitude of the contact length between tire and ground, so that, due to its shape and elasticity, tire actually behaves as geometric low-pass filter transforming real road profile geometry into effective vehicle vibration excitation. Since this effective profile represents real vehicle excitation, it is of interest to study this filtering behaviour in more depth. In this work, investigation of this kind of tire response has been studied for agricultural tractor tire rolling quasistatically over singular road obstacle. Frequency analysis of road excitation and tyre response was carried out in order to obtain their spectra and frequency response function magnitude of the tyre as filter was obtained by dividing input by output spectra. Final assessment of frequency response function magnitude was obtained by averaging instances obtained for different dimensions of input obstacles.

How Should We Develop the Careers of Our Employees? Organizational Career Management Tools in Focus
1-13Views:644We 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.

Exhaust System Muffler Volume Optimization of Light Commercial passenger Car Using Transfer Matrix Method
132-138Views:329Nowadays, the automotive industry is focused on weight and size reduction. Main advantage of this weight and size reduction are improving the fuel economy. The specific fuel consumption of a vehicle can be improved through e.g. downsizing area of heat loss, if we focus on vehicle with weight reduction. Weight reduction can be done by replacing material or by changing the size (dimensions) of components. In the present work we have focused on Audi A6 muffler, troubleshooting and optimizing the muffler by changing pipe length of inlet and outlet, also by replacing the original mesh plate to porous pipe. Based on optimization, prototype has been built with the help of 3D design tool CATIA V5 and the calculations of transmission loss (TL) have been performed by MATLAB. Plane wave-based models such as the transfer matrix method (TMM) can offer fast initial prototype solutions for muffler designers. The principles of TMM for predicting the transmission loss of a muffler was used. Result of this present study of an existing muffler has been analysed and then compared with vehicle level test observation data. Noise level have been optimized for new muffler design. Other literatures were played significant rule for validate our results.

Sections of Hungarian Contemporary Architecture and Fine Arts
115-122Views:312In my study I have examined the sections of Hungarian contemporary architecture and fine arts. In the historical overview it has become clear that two turning points have influenced contemporary arts: the total art work (Gesamtkunstwerk) of the Ghotic and Baroque styles. I listed the sections in three categories: metamorphosis, relationship and section. The sections are the highest level of these categories. I explained my research in detail by analyzing these sections, at János Megyik's art and his Gate statue at Life Science building and library at the University of Debrecen.
