Description:

The migration of highly skilled workers and its impact on productivity, competitiveness, and innovative development is becoming an increasingly relevant area of scientific research in the context of rapid digitalization of the economy. In this regard, the article aims to explore the relationship between the migration of highly skilled workers and digital economy development (using the example of EU countries). The study was conducted using correlation analysis and parametric data analysis methods, based on EU countries’ statistics on the migration of highly skilled workers, macroeconomic digitalization indicators, and the adoption of digital technologies at the business level. The results confirm that highly skilled migrants positively affect aggregate indicators of economic digitalization: correlation coefficients with the Global Digitalization Index and the DiGiX Digital Index are 0.735 and 0.692, respectively, and are statistically significant. At the company level, a significant influence of highly skilled migrants on the use of specific digital technologies in EU companies was confirmed. In particular, there is a strong correlation between the “Foreign Highly Skilled Personnel” indicator from the IMD World Talent Ranking 2024 and digital intensity indicators (level of application of key business-related digital technologies), as well as business activity in using big data analytics technologies: the correlation coefficients are 0.770 and 0.689, respectively, and are statistically significant. The proposed approach to analyzing the relationship between highly skilled worker migration and the digital development outcomes of companies and host countries can be used to develop and adjust knowledge and human resource productivity management strategies at both the micro- and macroeconomic levels.

Description:

Despite Kazakhstan’s unique natural and climatic features, rich recreational potential, and developed sanatorium infrastructure, the country has not yet become a competitive international tourist destination. In particular, the Akmola region, which has notable natural assets, remains underdeveloped in terms of tourism, and its potential is not effectively utilized to attract foreign tourists. This study aims to analyze the current state of tourism in the Akmola region, identify key problems, and propose possible solutions to enhance its development. To assess public perception, a 14-item questionnaire was created based on relevant literature and distributed via social networks. Survey questions were offered in the form of docs.google.com to facilitate distribution. A total of 503 respondents participated in the survey. Results show that Burabai National Park was recognized by 43.1% of respondents as having high tourism potential, followed by Kokshetau National Park (28.2%) and Buiratau (16.5%). At the same time, as for the attractiveness of tourist and recreational facilities in Akmola region, 57.1% of respondents answered that they are unique in nature, and 26.2% believe that ecotourism has great opportunities. Because the unique nature of Akmola region is a diverse landscape that includes: mountains, lakes, rivers, forests and steppes. However, 71% of respondents expressed dissatisfaction with the level of hotel development in the region, and over 50% emphasized the need to improve tourism infrastructure. The findings highlight the necessity of integrated development of the region’s tourist and recreational resources. In particular, it is necessary to repair the main roads, ensure the renewal of public transport and tourist routes. This allows us to provide accommodation in accordance with international standards, provide quality services at an affordable price and attract significant investment. Strengthening these aspects will not only improve the attractiveness of the region to global tourists but also contribute to the socio-economic well-being of the local population and foster the sustainable development of the Akmola region. Ultimately, the proposed strategies for the development of the tourism industry in Akmola region should be aimed at the effective use of local resources and increasing the competitiveness of the region, improving the socio-cultural level of the region by increasing the flow of tourists.

HF Pulse Signal Injection Based Method for Sensorless Control of PMSM with Cogging Torque Compensation

Karol Kyslan Grzegorz Tarchala Karol Wróbel Krisztián Horváth Viktor Petro

Description:

High-frequency (HF) signal injection methods are one of the key techniques for accurately estimating the rotor position of permanent magnet synchronous machines (PMSMs). The rotor position is determined by superimposing HF signals onto the fundamental control signals, producing a combined signal that serves as a reference for the PWM modulator. The rotor position is then extracted from the current response caused by the injected signal. This paper introduces a modification to the HF pulse signal injection method for sensorless control. The proposed approach improves control dynamics by reducing the signal injection period from two control periods to just one, and by adding the cogging torque compensation, thereby minimizing current and speed ripple. Experimental results obtained with a 2.5 kW PMSM and RT-LAB software obtained for the 1% of nominal speed validate the effectiveness of the proposed method.

Description:

Within the scope of the work, the possible use of fused deposition modeling (FDM) technology in executing rapid prototypes of cutting tools for aluminum sheets was systematically studied. Relevant investigations have thus far mainly concentrated on tools for the 3D printing of bent and deep-drawn pieces, yet the implementation of FDM tools in cutting has been insufficiently covered. This study aims to determine the characteristics of FDM cutting tools, such as wear and tear, dimensional stability, and cutting efficiency. Various tool designs were tested under different wall thicknesses and orientations with respect to the feed of Al99.5 sheets with thicknesses of 0.22 mm and 0.3 mm. According to the results, in the best case, three-dimensional printed PLA tools performed six cuts with no burrs and an acceptable wear level due to the IT tolerances (IT9 and IT10). Tools with thicker walls and more appropriate orientations were found to be more robust. However, some designs failed when subjected to greater loads, revealing a deficiency in some of the strength properties of the material. These observations suggest that it is possible to create 3D printed tools for modeling and small-scale production at considerably cheaper and faster rates than conventional methods. Future work will integrate advanced materials and designs to enhance tool performance, further solidifying FDM as a transformative approach in industrial tool manufacturing. With this research, the authors wanted to demonstrate that FDM technology can also be used to produce a classic sheet cut, which, of course, is still of great importance for prototyping or setting up production processes. This research demonstrated that FDM printing can play a role in this area.

Illuminating Inequality: Public Lighting Energy Consumption and Light Pollution in Urban and Rural Contexts

A. Zseni Dalma Schmeller Dalma Bódizs

Publication Name: Chemical Engineering Transactions

Publication Date: 2025-01-01

Volume: 121

Issue: Unknown

Page Range: 67-72

Description:

This paper investigates the spatial and social dimensions of light pollution through the lens of electricity consumption and technical losses related to public lighting across Hungarian municipalities, focusing on the Western Transdanubia region. Unlike traditional approaches based on remote sensing, this paper employs local-level electricity use data as a proxy for assessing light pollution intensity. Notably, several sparsely populated rural settlements display disproportionately high per capita electricity use and losses, suggesting inefficiencies, potential over-lighting, and elevated exposure to light pollution. The inclusion of technical losses provides a more accurate picture of systemic inefficiency that may contribute to excessive artificial illumination without corresponding social benefit. These findings underscore the relevance of electricity data as an indirect but actionable source for evaluating light pollution and energy waste. The paper advocates for more data-driven, environmentally conscious, and socially equitable lighting policies that integrate energy efficiency and light pollution mitigation into local planning frameworks. Based on data from 657 municipalities, total public lighting consumption ranges from under 10 MWh in small villages to over 1,000 MWh in large cities, with a regional average of 51.3 MWh (SD: 338.3 MWh). Per capita consumption varies between 0.002 and 0.02 MWh/person, with technical losses up to 17.9 kWh/person in some rural areas. These results indicate that energy inefficiency and light pollution are often more pronounced in small settlements, highlighting the need for regionally tailored modernization strategies addressing both energy use and environmental impact.

L. Akimova Halyna Mishchuk M. I. Karpa Oleksandr Akimov L. Akimova H. Karolyi

Publication Name: Ukrainian Geographical Journal

Publication Date: 2025-01-01

Volume: 2025

Issue: 3

Page Range: 75-86

Description:

Population migration is one of the natural phenomena that occurs in society regardless of the form of social and economic system, and is considered within the framework and at the intersection of various sciences. However, military migration has its unique features and a distinct landscape of its processes, occurrences, and ongoing developments. The subject of this research is the complex of problems related to military migration in Ukraine, as well as its impact on the socio-economic development of territorial communities. The article aims to map both visible situations and latent processes in the territorial communities of Ukraine caused by military migration during the Russo-Ukrainian War. It is demonstrated that the consequences of military migration have both positive and negative aspects, thereby becoming a source of conflict and contributing to a decline in living standards within territorial communities. The need to combine the efforts of government bodies, civil society, and stakeholders in a comprehensive study of the consequences of military migration on communities is emphasized to develop effective models and strategies to overcome negative patterns. The fundamental issues surrounding military migration are reexamined to incorporate some of the significant new field data that has surfaced recently and to outline the policy implications of the results.

First report of Xanthomonas arboricola on oleander

László Palkovics Anita Végh Attila FODOR

Publication Name: Phytopathologia Mediterranea

Publication Date: 2025-01-01

Volume: 64

Issue: 1

Page Range: 101-108

Description:

Nerium oleander L is a long-lasting flowering vegetatively propagated ornamental plant of the Mediterranean region, where it is a major imported flowering pot plant. Only a few bacteria can infect it such as Pseudomonas savastanoi pv. nerii, Agrobacterium tumefaciens and Xylella fastidiosa. Between 2018 and 2022 we collected several infected plant parts in our country. In 2020 we observed atypical symptoms on the leaves and stems, which were not clearly similar to the known bacterial infection of oleander. In our work, we aimed to identify the pathogen. The isolates formed yellowcoloured bacterial colonies on King-B and on YDC agar, were Gram-negative, oxidase negative and induced hypersensitive reaction on tobacco leaves. The biochemical properties were determined by API 20E and API 50CH tests. Brown necrosis was observed on oleander leaves in a pathogenicity test. Multilocus sequence analysis was used for molecular identification of the pathogen. Three housekeeping genes (gyrB, fyuA and rpoD) were amplified. According to symptoms, colony morphology, biochemical features, pathogenicity and molecular methods, the pathogen was identified as Xanthomonas arboricola. This is the first report of the plant pathogenic Xanthomonas spp. on oleander.
