In the footsteps of Artificial Intelligence : EExamining logical relationships between employee turnover and behavior patterns

Bernadett Domokos Zoltán Baracskai

Publication Name: 11th IEEE International Conference on Cognitive Infocommunications Coginfocom 2020 Proceedings

Publication Date: 2020-09-23

Volume: Unknown

Page Range: 569-572

Description:

In this study, the initial problem is the capacity of the human mind to set up a conceptual model. The novelty of this article is that we show that defined concepts created by the human mind can be passed on to an artificial intelligence-based expert system. The expert system helps the human mind to settle the logical connections between the defined terms and the conceptual model thus the created model will be better than what man could have set up without an expert system. These articles have examined the impact of employee turnover in countless aspects as one of potential index of a corporation. As a starting point for our research, we systematically reviewed the literature on employee turnover and selected six concepts that are bilaterally related to our phenomenon. Based on the terms and the correlation of it, we created a conceptual model that was examined with the help of an artificial intelligence-based system. Based on our experience in observing, consulting, and working with decision-makers, we examined the aspects of employee turnover phenomenon in the analysis. This was performed using a rule-based system, which used logical rules and found classical 'if-then' connections in the employee behavior cases. According to our examination, our outcomes can provide credible results for further research activities as well as for practitioners.

Level of presence in max where virtual reality

Borbála Berki

Publication Name: 11th IEEE International Conference on Cognitive Infocommunications Coginfocom 2020 Proceedings

Publication Date: 2020-09-23

Volume: Unknown

Issue: Unknown

Page Range: 485-490

Description:

Presence is the sense of being inside a virtual environment, that can be experienced also in desktop virtual realities not only in full-immersive VRs. MaxWhere is a desktop virtual reality that is used in education and for collaborative work. This VR can be considered as a 3D browser because in the space there are several smartboards where any web-content, document, or image can be displayed. This study compares the sense of presence in MaxWhere virtual reality to other desktop virtual realities with the Igroup Presence Questionnaire. This VR is in focus of numerous scientific research, thus this comparison of presence level could be a great starting point for them. The analysis showed that the level of presence in MaxWhere virtual reality corresponds to the average presence level in other desktop virtual realities. The analysis of the presence profile has shown that the general sense of presence and the spatial presence are relatively high in this VR. The experienced realism scale is the lowest because this VR is designed to foster working and learning inside the virtual space and not for having a high fidelity.

Genotyping of four loci in Hungarian yellow and broiler chickens

Károly Tempfli Klaudia Szalai Erika Lencsés-Varga Ágnes Bali Papp

Publication Name: Acta Veterinaria Hungarica

Publication Date: 2019-01-01

Volume: 67

Issue: 1

Page Range: 1-10

Description:

Traditional selection has led to remarkable differences in allele frequencies among various chicken breeds. Indigenous and broiler-type chicken populations were genotyped for polymorphisms in thyroid hormone responsive Spot14α, prolactin (PRL), IGF-binding protein 2 (IGFBP2), and somatostatin (SST) genes in order to determine potential utilisation type-associated allele frequencies. Significant (P < 0.05) differences were detected between Hungarian Yellow and broiler populations for Spot14α, PRL, and IGFBP2 allele frequencies, whereas the same SST allele (A) was fixed in both groups. In this study, the most significant associations (P < 0.05) were found between the IGFBP2 genotypes and the measured traits (body weight, carcass weight, breast muscle weight with or without skin, breast muscle weight as a percentage of carcass weight) in the broiler population. The results can be applied for the evaluation of polymorphism effects in the analysed populations; however, contradictory allele effects in different breeds and hybrids indicate the need for cautious marker utilisation in selection programmes.

Creative cities in Central and Eastern Europe-Examining the position of Gyor from the creative and cultural aspects of this macro-region

Szabolcs Morvay Dávid Fekete

Publication Name: Regional Statistics

Publication Date: 2019-01-01

Volume: 9

Issue: 2

Page Range: 45-66

Description:

The European Union is paying increasing more attention to the creative sector, acknowledging the economic significance of the sphere and appreciating the social benefits of creative and cultural activities. Its latest innovation is the Cultural and Creative Cities Monitor (CCCM), which shows the creative vibrancy of 168 European cities, thus enabling a comparison and ranking in terms of different creative and cultural aspects. Gyor has been included in this platform's list besides Budapest, Pecs, and Szeged. In this study the creative position of Gyor, in relation to similar mid-sized Central and Eastern European cities is examined, thus estimating the creative potential of Gyor. The analysis enables us to observe the elements and indicators of a creative city that are used to measure and show creativity. Exploring the city's strengths and weaknesses provides guidance as the CCCM annually renews its evaluation and changes the ranking. With conscious initiatives Gyor may become more creative, both internationally and locally. Based on the CCCM scores Gyor has numerous strengths: favourable geographic location, adequate amount of cultural offerings, strong economic potential, cultural vibrancy, and a high level of participation in cultural life. However, the city has weak features too, that require strengthening. The aim is for the cities to become more creative, but this requires analysis from the creative and cultural aspects. We offer an analysis that focuses on Hungarian cities, on our macro-region and on the creative and cultural elements of these cities.

Application of the walkability index in Hungarian small towns

Emese Makó Viktória Hideg

Publication Name: Pollack Periodica

Publication Date: 2026-01-01

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

AbstractThe assessment of walkability is essential for sustainable mobility and livable urban environments. This study explores the applicability of a walkability index - originally developed for a metropolitan context-to small towns in Hungary and identifies necessary adaptations. Data were collected through an expert survey on the prioritization and weighting of walkability factors. Weighting was determined using two methods: pairwise comparison and 100-point distribution, followed by linear normalization. Statistical analyses revealed that sense of safety and transport accessibility is more significant in small towns, while other factors, for example the attractiveness of the environment, are less emphasized. The findings support settlement-specific weighting of walkability criteria to address local needs.

Analyzing employee behavior related questionnaires by combined fuzzy signature model

Dalia Susniene Daiva Žostautienė Ojaras Purvinis Laszlo T. Koczy

Publication Name: Fuzzy Sets and Systems

Publication Date: 2020-09-15

Volume: 395

Issue: Unknown

Page Range: 254-272

Description:

The evaluation of data obtained from responses given to questionnaires in humanities and social sciences, such as management, linguistics, etc. is a complex task with the necessity of dealing with the inherent subjectivity and vagueness in such data. In this paper, a method based on fuzzy signatures (FSigs), suitable for analyzing questionnaires with hierarchically connected (partially) vague responses is proposed, and its applicability will be demonstrated by a real life problem; the partial analysis of an ongoing research examining employee behavior in various companies. The linkage of the factors hidden in the data bases obtained from the answers to the questionnaires, containing various factors interconnected in a more or less tight way, are represented by a hierarchical FSig system, allowing further evaluation and the discovery of emerging connections and deeper patterns among the responses, thus extending the idea of the original FSig model towards a more general, fuzzy-fuzzy signature approach. The method proposed here is a combination of some statistical elements with the Fuzzy Signature model, and it also uses Kohonen-maps in order to discover deeper structural components in the data pool. As FSigs are suitable to express hierarchically structured connections among vague and imprecise features of the individual data, the statistical analysis helps reveal the degrees of redundancies and the closeness of connectedness of the individual elements within the responses, and thus enable the construction of a relevant FSig tree graph for the data on hand, while further expert domain knowledge helps with determining the proper fuzzy aggregations in the intermediate nodes of the FSigs. The case study presented is based on data obtained from North Lithuanian companies. The results of the case study focusing on the analysis of the connection between OCB and CWB, and other factors, disclose some interesting and, partly unexpected, results. They indicate a strong and unambiguous relationship between career satisfaction and OCB, which is not very surprising. However, it is found that there is no relationship with gender, age, and actual position in the company, which are generally supposed to be determining factors. These results may be further validated by expert knowledge, and thus the new combined method for evaluating structured multicomponent data and internal dependencies is adequate.

Numerical methods for solving the modified filter algebraic riccati equation for H-infinity filtering

Zsolt Horváth

Publication Name: Przeglad Elektrotechniczny

Publication Date: 2019-01-01

Volume: 95

Issue: 4

Page Range: 9-15

Description:

This paper presents numerical methods for solving the Modified Filter Algebraic Riccati Equation (MFARE) for synthesis of H-infinity fault detection filters. Two methods are presented, namely the gamma-iteration and then rewriting the MFARE in Linear Matrix Inequalities (LMIs) and casting it as a convex optimization problem. Each algorithm has to ensure the condition for a global convergence and also has to deliver an optimal solution. Not at least the computational cost has to be as small as possible.

The most important city development initiatives of Hungary

János Rechnitzer Bálint Filep Judit Berkes

Publication Name: Regional Statistics

Publication Date: 2019-01-01

Volume: 9

Issue: 2

Page Range: 20-44

Description:

Recently, Hungary's urban development issues have been gaining increasing attention, while directions and institutional frameworks of regional politics are in a constant change. In this context, the study discusses the contents and connotations that can be linked to the territorial concept of major Hungarian cities; it also examines the changes in the position of these cities in the urban system. Major cities have a key role in territorial development as they facilitate spatial processes, and hence it is crucial to identify the weight and directions these centres with complex functions represent in development concepts. The formation or even restructuring of spatial processes require time. Since the democratic transition in 1989-1990, different development directions were assigned to major cities in short cycles. Cities have failed to adapt to these ever-changing objectives. The first part of this study presents the layers of the concept of major cities and characterize such categories as regional centre, city, county seat, and city with county rights. The second part tries to locate these centres, exploring changes in their developmental emphases, and also identifies pathways in the frequently changing territorial politics of the posttransition period.
