Cybersecurity Challenges in Agricultural Digitalization: A Systematic Review with Python-Based Analysis
33-47Views:431The intersection of agriculture and cybersecurity has become a prominent research focus in recent years, driven by the rapid adoption of IoT (Internet of Things) and precision farming technologies. These technological innovations have revolutionized agricultural processes, enhancing efficiency and sustainability while introducing significant security risks. This study conducts a systematic literature review (SLR) to address key cybersecurity issues in agriculture, with a particular emphasis on IoT vulnerabilities and threats. Using Python-based text analysis techniques, the research automated the analysis of abstracts and full texts, enabling rapid filtering and thematic categorization of relevant studies. From an initial pool of 1,039 publications, 40 relevant studies were identified based on rigorous screening criteria. The thematic analysis revealed that 44.9% of the publications focus on IoT device vulnerabilities, 32.7% on agricultural cybersecurity challenges, and 22.4% on the security issues of Agriculture 4.0 and precision farming. Methodological analysis indicated that machine learning, simulation models, and case studies dominate the research landscape, while surveys and experimental studies appear less frequently. The findings highlight the critical importance of developing robust cybersecurity strategies and technologies in the agricultural sector, particularly to mitigate the risks posed by IoT devices.

Monitoring of the Corporate Competitiveness Effect of Tourism Support
603-616Views:293Today the tourism is without doubt strategic of importance in the world. In Hungary's case can be related, that contributes to the performance of the economy largely, and its role is very important in the employment, too. Because of national economic weight it is suitable to analysing, but for the sake of complexity the consideration of economic performance, competitiveness exceptionally complicated task. The two sections are attached most directly, the performace is measurable through the accomodation service and hospitality. Present study does not intend to measure the performance of whole tourism section, the aim is from a corporate side, measure the corporate competitiveness from accountancy datas, the examination of part. The object of the actual examination is monitoring of the profitability effect of tourism supports through the example of 8 companies.

Issues of Regional Social Innovation
602-616Views:397Social innovation is not determined as a uniform definition, after a literature review can be defined as follows: social innovation is an innovative and new way of improving community well-being [2]. Social innovation can be defined and measured at micro-, mezo- and macro level similar to technical and economic innovation and plays a key role in the competitiveness. Because of imbalances arising from different levels of economic development, catching-up demand of peripheral settlements have appeared. In addition to the so-called technical innovations, the solution of social problems can be achieved by social tools, methods and new organizations. In catching-up process the local, community level construed innovative ideas and the activities of social innovation play a significant role. The expansion of the innovative areas results in different innovation processes and they can be considered as complementary processes. The social and technical innovation are closely interacting. If there is achange in the economic sphere, social change can occur. This study examines the role of local communities in social innovation at regional level and summarizes the clarifying questions of implementation. Social innovation as a new tool is able to answer daily challenges. The innovative solutions of municipalities, which means new collaborations, result sustainable, flexible and open leadership at regional level. This study will examine the role of governments (or their institutions) in the implementation and generating of social innovation, the tasks of regional innovators and social solutions and models of certain municipalities in Hungary and the European Union.

Determination of the Differential Equations of a Dynamical System using Dual Description
41-48Views:187The paper deals with the description of a mathematical model of a mechanical system using the so-called energy-based approach. The model is created using both generalized displacements and generalized momenta. The latter prescription method is less common in practice, due to its complexity. The two ways are presented through the same example mechanical problem, and a control task is also solved with the help of a PID block.

Future Power Plant Portfolio Analysis from the Point of View of Minimum Cost and Emission Optimization
61-77Views:259The article examines the expected composition of the power plant portfolio in Hungary by 2030. The indicators considered are the life-cycle unit costs (LCOE) and the life-cycle specific carbon dioxide emissions (LCA(CO2)) of the power plant types. The minimum of these two indicators, as objective functions, is determined by a linear programming method for the power plant portfolio. The results show that the LCOE minimum for the power plant portfolios in 2030 is worse in absolute terms and better in specific terms than in 2021. In both absolute and specific terms, the LCA(CO2) minimum is more favourable in 2021. These results are met under the thirty and twenty-five percent electricity import scenarios. With twenty percent imports, the absolute values are worse and the specific values are better for both indicators. On the other hand, the results of the calculations for 2030 fall short of the 2030 Agenda of the Institute for a Green Transition. This is due to the delay in commissioning a new nuclear power plant and the transformation of industry with increasing electricity demand. For the portfolios under review, a minimum of thirty percent of domestic generation from renewable sources is met. This contributes significantly to the European Union's ambition for the sector to be net greenhouse gas-free by 2050.

Examining the Competitiveness of Fish Products on the Market
151-163Views:243Fish and fishery products are one of the key ingredients in human nutrition and are therefore outstanding in terms of both production and trade. Different processed fish products are available in many countries around the world due to globalization and a fast supply chain. In our study, we examined the market for fish and fishery products using secondary data collection. The data were collected several years ago from the databases of FAO, EUROSTAT, COMTRADE and KSH The comparative advantages or disadvantages of international trade were determined with the help of the RCA index for the role of Hungary and the EU in the world in the case of different categories of fish products. The aim of our research is to compare the fish products of different processing in Hungary and in the EU compared to the international situation, paying special attention to the main exporting and importing countries. Based on the secondary research the study has a detailed the specificities of trade, the trends observed in recent years and the competitiveness of fish products in Hungary and the Member States of the European Union and effect relationships behind the RCA-index results.

Opinions of Higher Education Students about Internships and Working while Studying
286-297Views:592The importance of working while studying in higher education has a globally growing tendency, and Hungary is not an exception. The demand for the opportunities of student employment has been recognized not only by the students but also by the policy makers of higher education, leading to the introduction of solutions like the obligatory internship semesters or the dual training programs. The current study contributes to the better understanding of this field through the analysis of a database from a questionnaire survey conducted among bachelor students from seven majors of the University of Debrecen during the Fall semester in 2015 (N = 589). The main findings suggest that the students mostly consider the internships as an investment into their future career while the short term compensation and the personal interests have a lower importance for them. About 75% of the students would be willing to work not more than 20 hours a week, and most of them would look for ‘official’ studentwork. For working, they would sacrifice the time connected to the following activity-areas (relative to the other activities in the list, and in descending order): time for leisure (this is the most likely to be sacrificed), for sport, for friends, for family, and for learning (this is the less likely to be traded in for working hours). Willingness to work (measured in daily working hours) seems to be connected to the following factors: major, year of study, how important the activity areas are considered compared to working (learning, family, friends, sports, leisure), and the importance of finding a personally interesting internship.

Analysis of the Causes and Effects of Noise from Rail Transport
116-130Views:331Noise emissions from rail transport are a major concern, as they affect both the environment and people's health and quality of life. Among the many sources of noise emissions, rail vehicles and infrastructure are a major factor. With regard to rail noise emissions, it can be concluded that noise effects are influenced by a number of factors. These factors include train speed, track condition, traction technology and the noise abatement methods used. The negative effects of noise exposure include sleep disturbance, stress and mental health deterioration. It also affects the quality of life of people in urban areas and property prices. It should be emphasised that reducing noise emissions from rail transport is key to creating a healthier and more sustainable urban environment. To achieve this, it is important to use modern noise abatement technologies, improve infrastructure and implement noise abatement actions effectively. Transport authorities and railway companies should work together to achieve a more noise-free rail transport, to improve people's quality of life and to protect the environment.

3X3 Basketball Tournaments in Debrecen
231-250Views:438Faster attacks, spin speed, increased adrenaline levels, vehement play. This is all about the 3X3 basketball. In Debrecen, the first 3X3 basketball matches were held in 2015, most of them did not even think that the sport would be popular in Hungary as well. Practically, from the start of the first minute, the games were played with great success. Following the successful settlement, the International Basketball Association immediately offered a 3-year contract to Debrecen. The purpose of our research was to examine the 3X3 basketball tournaments in Debrecen, which was analyzed using a questionnaire and an in-depth interview. 69% of the respondents participated in the 2016 and 2017 events, but only 37% attended the 3X3 basketball tournaments that were held for the first time in 2015. It can be stated that this trend is growing and the event is gaining popularity nationwide. Sponsors and sponsors covered every issue of the event so the event was free of charge over the years. 72% of fillers, however, are willing to spend money on a possible entry fee. In terms of revenue growth, the introduction of admission fees is unlikely to reduce interest. Up to 1200 seats have been filled up for the event every year. Therefore, it is not surprising that a lot of people would like to enjoy a higher auditorium with more space. The introduction of 4-point boundaries (3 points) for 3X3 matches would be a great opportunity to try the "little brother" of basketball in the 4-point so that it can be introduced in traditional basketball. Hungary became the pioneer of the sport due to the results of the Hungarian national team and the successful organization of sporting events.
