EMPLOYEE ATTITUDE TO ORGANISATIONAL CHANGE IN SMALL AND MEDIUM-SIZED ENTERPRISES

P. Karácsony Judit Petra Koltai Zdenko Metzker Tihana Vasic

Publication Name: E A M Ekonomie A Management

Publication Date: 2023-01-01

Volume: 26

Issue: 1

Page Range: 94-110

Description:

The crisis caused by the coronavirus pandemic affects the daily operation of organisations, which also brings changes in the life of their workforce. Managing organisational change has been a significant challenge for organisations for several decades. The aim of the research is to assess the behaviour of affected employees toward organisational change. It is examined how different groups of employee’s experience change in general and what they think about organisational change. Furthermore, it is explored whether employees understand the motivation behind the change and how does the change impact their organisation. To answer the research questions, a comprehensive questionnaire survey of small and medium-sized enterprises in Hungary was conducted in autumn 2021. The suitability of the application of factor analysis evaluating the dependence of selected areas of the questionnaire was supported by Barlett test a Cronbach’s alfa coefficient. For individual hypotheses two-sample t-test, contingency table analysis, and Pearson’s Chi-squared test, were applied. The evaluation of the 215 questionnaires shows that the behaviour of employees toward organisational changes is different. The difference in attitudes to the benefit of organizational change for employees were identified, but not for enterprise. Furthermore, the difference in attitudes between employees who have undergone organizational change in the enterprise and those who have not undergone organizational change, were identified too. It is interesting that contingency between the extent to which managers play a role in change and the well-executed nature of change were detected. The practical usage of the research can be helpful for SME management, especially in the HR field. The management can consider that employees may be afraid of the changes if they are ahead of them, but if the change is handled well, people will think positively of it.

"Green" Tram Tracks for the Sustainability of the Urban Environment

Zoltán Major Herta Mária Czédli Cecília Szigeti

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 289-294

Description:

Greening tram tracks has ecological, urban planning and economic impacts. Greening of the tracks supports the development of sustainable stormwater management as well as improving the visual appearance of the city. The restoration of the natural water cycle is achieved through water-sensitive design: the innovative solution used achieves both the retention of water, the reduction of run-off and the increase of the surface area available for evaporation. The literature data (Grüngleis Netzwerk, 2011) show that 50-70 % of the annual precipitation projected onto the green runway is absorbed and re-evaporated. The urban climate impact of the vegetation systems to be developed is most pronounced in the summer months. The microclimate of green track environments has a positive impact on the health of the population. Our work will investigate the effects of green vegetated areas. In this study, we analysed the ecological impact and the capacity to sequester of carbon dioxide from the atmosphere by photosynthesis of grass- and crowfoot-lined tracks. The Sedum green roofs quantified carbon storage is approximately 160 gC/m2 during a two-year period (Collazo-Ortega et al., 2017). The concept of a vegetated track leads to an improvement of green space indicators in a complex system of urban environments through the correct choice of vegetation plants. Prioritising and encouraging the construction of green tracks is one of the possibilities to make the urban environment more livable. It is also necessary to encourage this at the regulatory level in cities.

Page Range: 59-64

Description:

With the appearance of 2D graphical user interfaces in the 1980s, users began to carry out most operations on 2D icon-based interfaces instead of using line-based terminals. With the emergence of smartphones in the 2010s, the notion of portable 2D graphical user interfaces was born, and by today, users accessing digital services are no longer tethered to a single location. All of these advances have led to immense changes in our conceptualization of digital information systems, the effects of which are difficult to overestimate. Recent developments in virtual and augmented reality (VR/AR), as well as in Internet of Things (IoT) and artificial intelligence (AI) are poised to lead to the next major breakthrough in this series of cognitive expansions, bringing to the forefront portable, context-aware spatial interfaces. A consequence of these developments is that users are expecting to be able to access a growing multitude and variety of digital content in ways that are increasingly contextualized and personalized, i.e., relevant to the time, location and topic from the perspective of the users' personal history. In this paper, we propose an adaptive content labeling and storage model that is suitable to these challenges. Our model, called the Graph-Indexed Tensor Store (GITS) has the benefits of being adaptive and personalized, while also allowing for content retrieval to be carried out based on associative search operations. In a preliminary analysis of the model, we address the challenges of what we refer to as syntactic, semantic and pragmatic saturation, and provide ways to quantity and further explore their effects.

Description:

The genus Micherdzinskiiobovella Hirschmann, 1989 (Mesostigmata: Uropodina: Uropodinychidae) is resurrected for species of the Uroobovella micherdzinskii-group. This genus differs from the other taxa of the Uroobovella sensu lato based on the shape of body, the first gnathosomal setae, the peritreme and the number of the ventral setae. All species from the Uroobovella micherdzinskii-group are moved to the genus Micherdzinskiiobovella, as M. japonica (Hiramatsu et Hirschmann, 1977) comb. n., M. levigata (Hirschmann et Hiramatsu, 1990) comb. n., M. makilingensis (Hirschmann et Hiramatsu, 1990) comb. n., M. mitakensis (Hiramatsu et Hirschmann, 1977) comb. n., M. pauxilla (Hiramatsu, 1981) comb. n., M. pauxillaoides (Hirschmann, 1981) comb. n., M. similimitakensis (Hirschmann, 1981) comb. n., M. topali (Hirschmann, 1981) comb. n., and M. multisetosa (Kontschán et Starý, 2011) comb. n. A new species (M. petofii sp. n.) is described, based on one female and four males collected from Singapore. The new species differs from the congeners in the length and shape of the ventral setae.

Publication Date: 2023-01-01

Volume: Unknown

Issue: Unknown

Page Range: 71-76

Description:

To make machines emotionally more intelligent, it is necessary to choose the right measuring devices that are able to collect physiological biosignals, which can be used to recognize the emotional state of the user. These devices should not restrict the users in their everyday life, therefore commercial, non-invasive Internet of Things (IoT) devices must be used. Thanks to the interoperability of IoT devices, it is possible to send the obtained data to a server, where it can be used in the predict method of a trained machine learning algorithm. Based on the recognized emotion, it is possible to create different instructions for smart home elements.

The Future of Health Management—How Virtual Reality and 5G Networks Can Contribute to Sustainability in Healthcare

József Tollár Gyorgy Wersenyi

Publication Name: Springer Proceedings in Business and Economics

Publication Date: 2023-01-01

Volume: Unknown

Issue: Unknown

Page Range: 459-470

Description:

Developments in healthcare usually directly target innovations in intervention techniques and medical devices for diagnosis, analysis and treatment. On the other hand, digital development in administration, handling and accessing (sensitive) patient data or real-time availability of information also contribute to improvement of management. The CoVid situation highlighted emerging technologies that covers both, and blurs the border between, management (i.e., cost reduction) and actual treatment. The newly introduced 5G New Radio wireless technology and the expansion of virtual, augmented and mixed reality applications not only assist medical personnel during treatment, but can increase safety, availability and sustainability of services, and at the same time, can reduce costs. This paper briefly introduces benefits of these technologies focusing on state-of-the-art use cases.

Sustainability in Folk Culture: Transmission of a Traditional Blue Dyeing Technique in Győr

Zsuzsanna Lanczendorfer Balázs Varga

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 235-240

Description:

Based on blue-dyer masters’ experience, we can say that people are still interested in the technology of traditional blue dyeing. There are many people participating in trade shows. Moreover, people tend to buy and use the products produced this way. Based on the proposal of the Intellectual Cultural Heritage Professional Committee of the Hungarian National Committee of UNESCO, the tradition of blue dyeing became part of the National Register of Intellectual Cultural Heritage in 2015. Then, in 2018, to the proposal of five countries, including Hungary, the traditional trade of blue-dyeing was recognised, which thus became part of the list of intellectual cultural heritage of UNESCO. In the elaboration of the petition of nomination, a master of Győr, Ildikó Tóth and her family participated. In our study, we are giving an overview of the history of blue-dyeing, which can be dated from the end of the 17th century, of the spreading of the main techniques, and also of the state of the number of blue-dyers. Beyond the above-mentioned issues, we are dealing with the history of blue-dyeing in Győr, mentioning the more important masters, as well as the mark of the trade, which can be seen until now. In the main part of our study, we are introducing a blue-dyeing workshop in Győr, where they manufacture textiles using original devices and technology until the present day. Apart from this, we are pointing out the family story of the blue-dyer family Éhring, which embraces five generations. Moreover, we are presenting their work done in the survival of our cultural heritage, in popular education and community development, with the help of the interviews made with Ildikó Tóth and her family – who has recently received the title ‘Master of Folk Culture’. In the study, we are also publishing true stories about blue-dyer masters, about the trade and the above-mentioned family.

In vitro evaluation of certain probiotic properties of lactic acid bacteria isolates

Judit Süle Zoltán Hatvan Z. Kerényi László Varga

Publication Name: Elelmiszervizsgalati Kozlemenyek

Publication Date: 2023-01-01

Volume: 69

Issue: 1

Page Range: 4350-4363

Description:

Bacteria carrying genes responsible for antibiotic resistance cannot be used in food production. For this reason, exploring the antibiotic resistance profile of probiotic candidates and the antimicrobial substances they produce are essential for probiotic strain selection. The aim of this study was to develop and evaluate additional elements of a complex in vitro test system for rapid and efficient selection of a large number of putative probiotic isolates. In a previous work, we had tested bacterial strains (n=217) isolated from Transylvanian raw sheep milk, cultured sheep milk, and sheep cheese samples and we reduced the sample number to a total of six Gram-positive, non-hemolytic, catalase-negative, well-aggregating, good acid and bile acid tolerating strains. In this research, we investigated the antibiotic resistance and antimicrobial production capacity of the pre-selected strains (n=6). The antimicrobial activity of the isolates was determined by the agar well diffusion assay. Strains E15, E66, E173, E198, and E216 were found to inhibit the growth of both Salmonella Enteridis ATCC 13076 and the control strain (i.e., Lactobacillus acidophilus ATCC 4356). Antibiotic resistance tests were performed by the agar disk diffusion method. All six isolates belonging to the species of Levilactobacillus brevis and Lactiplantibacillus plantarum were found to be resistant to several antibiotics and, therefore, cannot be used for the manufacture of commercial probiotic products. In conclusion, our in vitro test system proved to be capable of effectively screening out unsafe isolates.
