SOCIO-ECONOMIC INTEGRATION OF MILITARY VETERANS IN UKRAINE: PUBLIC PERCEPTIONS AND POLICY CHALLENGES

Publication Name: Problems and Perspectives in Management

Publication Date: 2025-01-01

Volume: 23

Issue: 4

Page Range: 232-246

Description:

Military veterans constitute a distinct social group whose socio-economic integration is becoming increasingly urgent due to the growing number of veterans, which today approaches one million individuals. The aim of this study is to assess the problems related to the socio-economic integration of military veterans and to explore potential solutions, taking into account public perceptions and the population’s readiness to support veterans. In 2024 a sociological survey targeted 516 veterans and 850 members of the general population in Ukraine. Data were processed using IBM SPSS Statistics (version 20). The findings indicate that, despite certain societal stereotypes, the relationship between these groups is predominantly positive. The mean population assessment of conflict in relations does not exceed 2.35 points (on a five-point scale), while veterans’ assessments do not exceed 2.75 points. Veterans’ relations with state authorities responsible for social guarantees are less favorable, with evaluations ranging from 2.46 to 3.24 points. The most prevalent form of support for veterans is the willingness to provide financial or material assistance (20.6% and 24.4% of respondents, respectively). There are promising conditions for encouraging support for veteran-led businesses: 7.8% of respondents indicated a preference for purchasing goods from such enterprises. Furthermore, 9.1% of respondents expressed support for the development of economic incentives for companies established by veterans or employing veterans. The results provide a basis for improving state programs for veteran integration, suggesting that traditional support measures may be significantly strengthened by policies aimed at increasing veterans’ active participation in economic life.

Emotion-based insights into pro-environmental video campaigns: A study on waste sorting behavior in Ukraine

Publication Name: Environmental Economics

Publication Date: 2025-01-01

Volume: 16

Issue: 2

Page Range: 50-72

Description:

This study aims to examine how different types of pro-environmental video content (featuring humans versus AI-generated characters) influence household waste sorting attitudes and behaviors among Ukrainian residents. The research was conducted in two stages using a mixed-method approach. In the first stage, 102 individuals aged 18-45 watched two videos on waste sorting and completed an online questionnaire. Cluster and variance analyses were performed using Statistica software. In the second stage, 35 participants underwent a laboratory-based emotion analysis using iMotions software, heart rate monitors, and galvanic skin response sensors at the Behavioral Lab of Sumy State University (Ukraine) from May to July 2024. The results revealed that videos featuring real people were more effective in generating interest (average rating: 3.5 vs. 3.2) and emotional engagement, particularly joy and contempt, which were the most frequently expressed emotions. Cluster analysis identified four distinct respondent groups. Cluster 1 (39.2%) - primarily young women - responded positively to human-led videos but showed limited behavioral change. Cluster 2 (19.6%) - women aged 26-35 - reacted positively to both videos and were most willing to adopt waste sorting behavior. Cluster 3 (23.5%) - primarily men - showed moderate engagement and sorted waste occasionally. Cluster 4 (17.6%) - highly educated women - exhibited the least positive responses and were least likely to change their behavior. The emotion analysis confirmed that videos featuring real people elicited stronger emotional responses across all categories, whereas AI-generated videos prompted higher levels of anger but generally weaker engagement.

Genotyping of four loci in Hungarian yellow and broiler chickens

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.

Military-Legal Foundations of Maintaining an Empire. The Development of Hungary’s Defence System in the Austro-Hungarian Empire

Publication Name: Journal on European History of Law

Publication Date: 2025-01-01

Volume: 16

Issue: 2

Page Range: 101-109

Description:

This study hypothesizes the gradual emergence of a defence and security constitution within the broader constitutional and state-building processes of the Hungarian part of the Austro-Hungarian Empire. While the 1867 Compromise established a dualist constitutional framework for political governance, it also triggered a parallel institutional and legal evolution in the field of state defence and security. The evolution of this defence and security constitution and the modernization of Hungary’s defence system - beyond their historical significance - might offer a valuable framework for addressing today’s security challenges. The research draws on primary sources, including legal texts and historical documents, as well as secondary literature and employs a historical-legal approach, analyzing the development of Hungary’s defence institutions and their constitutional framework.

The assessment of financial risks of municipally owned public utility companies in hungary between 2009 and 2018

Publication Name: Montenegrin Journal of Economics

Publication Date: 2020-01-01

Volume: 16

Issue: 4

Page Range: 29-41

Description:

The aim of this study is to assess the financial risks, as interpreted by us, of Hungarian corporations fully owned by municipalities across a national dimension after the global economic crisis broken out in 2008. In this study, financial risk was measured by profitability, liquidity and the equity ratio. We were seeking an answer to the question as to how more stringent state controls had influenced the companies’ ability to provide public services and their financial situation behind in a more robust public financial regulatory and control environment created in Hungary after 2010, that is, how the going concern principle of accounting had been implemented. Indirectly, we were also seeking an answer to the question as to how operational risks had been affected by the “breaking” effect on net income exerted by the administrative price regulation (reduction of utility costs on the consumers’ side) imposed on the services of public utility companies in 2013 (as part of the public finance re-form introduced in 2010), that is, whether a more robust regulatory environment of public finances compelled the promotion of corporate efficiency. With the complex (and inter-related) methodology of the assessments carried out, we could establish that financial risks improved, but we propose even stricter controls due the economic shock caused by the COVID-19 pandemic. Our research results present a comprehensive situational picture of municipally owned companies providing public services in an emerging market economy, which can be compared with the data of other countries as well.

Cubature kalman filter-based speed sensorless control of induction machines

Publication Name: 2018 20th International Symposium on Electrical Apparatus and Technologies Siela 2018 Proceedings

Publication Date: 2018-08-24

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

In this paper, a new speed sensorless control algorithm is introduced for induction machine (IM) drives, which utilizes the cubature Kalman filter (CKF) as state estimator. The CKF is a relative new approach to nonlinear state estimation, which uses a spherical-radial cubature rule in order to compute numerically the multivariate moment integrals. Using an augmented state space model of the IMs, CKF provides load torque estimation and sufficient control performance under difficult operating conditions. The proposed control algorithm is validated by MATLAB simulation in this work.

Optimal parameter extraction of equivalent circuits for single- and three- phase Power transformers based on arctic puffin algorithm accomplished with experimental verification

Publication Name: Results in Engineering

Publication Date: 2025-06-01

Volume: 26

Issue: Unknown

Page Range: Unknown

Description:

The power transformer is a critical device in power systems. This paper addresses one of the major problems which hopes to enhance the accuracy of estimation of parameters, which is critical in power transformer modeling, maintenance, and operating efficiency. In that context, this work estimates the parameters of single- and three-phase power transformers by a new optimizer called Arctic Puffin Optimization Algorithm (APO). The algorithm is intended to improve estimation of transformer parameters with the goal of reducing the error incurred between the estimated and actual values of the parameters. To verify the accuracy of the APO, experimental measurements were conducted on single- and three-phase transformers. The assessment of the algorithm's effectiveness was performed against the effectiveness of other commonly used estimating methods. The results have shown that APO increases the accuracy of estimation of the parameters of both single- and three-phase transformers to considerable levels. Dependability of the APO was established by experimental verification, which disclosed an ultimate connection between the resultant quantities and actual measurements. The study also confirmed APO can be useful for transformer parameter estimation because APO converges more rapidly and more precisely compared with traditional methods of the literature.

First report of Serratia marcescens from oleander in Hungary

Publication Name: Phytopathologia Mediterranea

Publication Date: 2022-01-01

Volume: 61

Issue: 2

Page Range: 311-317

Description:

Oleander (Nerium oleander L.) is a popular woody ornamental plant, often used for decorating public areas, terraces and gardens. Many diseases may decrease in the ornamental value of these plantings. Between 2018 and 2020, plant pathogenic bacteria of oleander were examined, and many samples of infected plants were collected from different sites in Hungary. Two non-pigmented Serratia marcescens isolates were identified from oleander by classical and molecular methods. The isolates caused necrotic lesions on oleander leaves. Serratia marcescens is known as an opportunistic mammal or plant pathogen, but non-pathogenic strains are known to be useful biological control agents or plant growth-promoting bacteria. This is the first report of the plant pathogen S. marcescens from oleander, and the first identification of the bacterium in Hungary.
