The Situation of Digitization in the Hungarian Food Processing Industry
196-209Views:505Thanks to various technologies, such as nanotechnology, the next decades will completely transform the individual production processes and sectors. With the rapid advancement of information technology, the digitalization and automation of industrial processes pose new challenges for food business operators. Hungarian food companies will be able to keep up with their competitors and be the winners for the next decades if they can successfully adopt these technologies. However, this requires a strong focus on digitization, digital strategy, and directing investment, technology change and R&D activities in this direction. Digitization is one of the decisive directions of the future, which is why I felt it essential to study the level of digitization of Hungarian food companies, IT infrastructure and Internet usage, the use, and role of enterprise management systems, decision support and business analysis tools, and business readiness, Industry 4.0 technology change. Based on the 205 evaluable responses to the questionnaire, it can be said that only a tiny proportion of Hungarian food companies have a digital strategy and only a few have digital transformation.

Statistical Evaluation of University Student’s Motivation and Personal Competency with Principal Component and Cluster Analysis
365-374Views:296The 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.

Impacts of Digital Communication Tools on Fashion Brands Success –The NUDE Project
1-13Views:514The global scale, changing fashion industry can be characterised with low predictability, high volatility, seasonality, short life cycle products and highly impulse consumer purchasings decisions, addressing ethical and sustainability matters. Fashion as generic collecting name can be defined as styles of clothing and accessories worn at any time by different groups of people. One of the main opportunity and challenge for this complex, multi actors sector introducing digital solutions, which can provide significant contribution of restructuring the supply chains, optimising the production techniques, reducing its negative environmental externalities supporting the future sustainability. Possible reason beyond this digitization trend can be changing consumer attitudes and expectations. Majority of consumers have tendency using digital channels before, during and after their purchase, so fashion brands have to take into consideration this new reality. The convenience and accessibility of online enjoyable shopping opportunities have reshaped consumer expectations including personalized recommendations, and user-friendly online social media platforms (video channels, websites, mobile apps, and secure payment systems). Instagram, TikTok, YouTube and Pinterest have transformed the way fashion brands communicate and connect with their audience creating loyal social network. Digital transformation requires more than just implementing new technologies; it necessitates a cultural shift within fashion brands. Case study of the NUDE Project analysing its challenges and main competitors as well, can serve as an illustrative example how can the digital communication tools contribute to the fashion brand future success and prosperity.

Environmental Index and Environmental City Resilience Index calculation for Four Settlements in Szabolcs-Szatmár-Bereg County and Four in Győr-Moson-Sopron County
17-29Views:245Globalization and urbanization pose a number of challenges for different settlements. Stakeholders seek to cure global problems through sustainable projects. Since the Brundtland Commission's definition of sustainable development in 1987, the approach to sustainability has permeated all dimensions of the economy, including the environmental dimension. In Hungary, IBM conducted a study (Lados - Horváthné Barsi, 2011), in which the search for green, sustainable solutions defined in the definition of a livable city plays a key role. The characteristics of sustainable cities, that they are resilient to disasters, return to equilibrium after a shock has occurred (Seeliger, Turok, 2013). Resilience can also be mentioned as one of the pillars of sustainability. In a UN-Habitat statement, resilience refers to the ability of any urban system to withstand and recover from multiple shocks and to maintain the continuity of its services (OECD, 2018). In my study, I would like to present the results of the environmental index and the Environmental Urban Resilience Index (EURI) of the four largest cities selected on the basis of the population in the easternmost and westernmost counties of the country.

Survey of population knowledge on the technical characteristics and physiological effects of light pollution in two settlements
155-161Views:251One of the newest environmental challenges in our industrialized world is light pollution. It means that we emit more light than necessary, and this is often done at wavelengths that are both disturbing and even harmful to human health. The Dark Sky Parks, where over a large area there are no artificial light sources that burden the environment. One of these parks is located in BAZ County, near Répáshuta, and is under continuous development. Our study reports on a questionnaire survey conducted in Répáshuta, which is informed about light pollution, and in Cserépváralja settlements close to it, but without direct knowledge of the problem. The population of both villages is around 400. With a direct on-site survey, we asked 21-21 questions to 30-30 person and received answers in all cases, of course, taking full account of the anonymity of the respondents. Recruitment took place in March and April 2019.

Menedzsment módszerek az Ipar 4.0 tükrében
507-514Views:811The fourth industrial revolution poses major challenges for organisations in terms of technological aspects and from a management point of view, too. Good (effective) management is vital as it can help overcome the difficulties arising from shortages of skilled labour and from cost-cutting pressures, and it can help improve efficiency of resources. Innovations require management methods that support the introduction of industry 4.0. In my review of the literature, I aim to find out how the current level of sophistication in this new field can help managers of SME to better embrace change. Based on the reviewed literature, from management point of view, organisational structure, leadership style and HR practices are key to creating an atmosphere conducive to learning and innovation. In terms of structure, researchers do not suggest one thing to apply, but emphasise that industry 4.0 is characterised by an unstable, changing environment, so it is worth developing a structure that is characterised by decentralisation, few rules, horizontal communication and collaborative teamwork, i.e. much more organic than mechanical. In terms of different leadership styles, it is the transformational leadership that is the most often mentioned, however, in case of industry 4.0, we need even more because it can have various limitations. Even before industry 4.0, literature has highlighted that the recommended leadership style can be defined as the combination of transformational and transactional leadership; research in industry 4.0 in recent years also emphasises that it is the expanded construction of a knowledge-driven leadership style that blends the two, which can best facilitate innovation and learning. Managers can develop employee skills and improve their learning abilities through a variety of HR practices. So the right structure, leadership style and HR prepare the organisation for industry 4.0 by facilitating learning, improving skills and innovation.

Application of Heutagogical Methods in Entrepreneurship Education
364-373Views:234According 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.

Challenges of the Quality- and Change Management in the Context of Upcoming Social-Industrial Changes (5.0) – Conclusion of a Survey
138-150Views:325The upcoming industrial-social revolution, which may be called the 5.0, is emphasizing the coordination of the value-creating work of technology (machine) and man. This approach wishes to move towards sustainability, which deserves a significant role in nowadays through the world empathizing the negative effects of the wolrd. During my research I was looking for the answer that how the extended industry 4.0 and its tone be in Hungary via supply chain of the automotive industry. During my research I was looking for the answer that how the extended industry 4.0 be in Hungary and its tune through supply chain of the automotive industry. I also have examined that which changes are justified regarding management systems in interest of efficiency and emphasizing the human capital by leaders interviewed. As a part of qualitative research in-depth expert interviews were interpreted with help of content analysis based on the methodology of grounded theory. The results demonstrate the need to review and change existing processes in order to ensure that the potential of human capital is not lost and that technological development, even more so, is at the service of human resources in order to achieve its efficiency and effectiveness. Among the possible tools we can find the re-structurizing changes of post tracking processes of the audits in management systems providing quality. Furthermore, the practical implementation of multifactorial statistical process control in the evaluation of processed data, which may be one of the essences of industrial (IoT) data.

The Legal Aspects and Challenges of Managing Workplace Mobbing
1-9Views:827Workplace mobbing (psychological harassment) can be a great challenge for the management of any organization. Although the phenomenon has been discovered for quite some time, there is still no unequivocal definition, and therefore preventive and managerial actions are rudimentary. It is clear that mobbing affects not only on the individual employee, but the whole organization. The reduction of commitment of people working in this environment (and not only those directly affected by it) may have a detrimental effect on the performance of the organization. I will present a legal case study to highlight some of the general and procedural shortcomings of mobbing at the workplace.
