Cybersecurity Challenges in Agricultural Digitalization: A Systematic Review with Python-Based Analysis
33-47Views:284The 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.

Maintenance from the Work Safety Point of View
190-196Views:219Deterioration of the technical condition of plant equipment is a common phenomenon nowadays. According to the experience of authorities, all this contributes to the occurrence of malfunctions and accidents. Plants that operate with an inadequate conservation strategy are now nearing the end of their design life, thus posing an increased accident risk. Aging processes are often accelerated by the operator's underestimation of the effects of equipment stress and the extent of deterioration mechanisms, and the consequent inadequate design and operation of condition monitoring and maintenance procedures. The aim of our work is to examine trends in the light of modern maintenance optimization methods and, in connection with this, to make proposals for the optimization of maintenance scheduling for employers.

The role of the nonprofit economic companies in human resource management in Hungary
145-152Views:246In the changed labor market structure in the context of economic growth in Hungary, the reintegration of displaced and increasingly differentiated groups into the world of work has become an indispensable necessity, with alternative initiatives aimed at long-term profit maximization. Nonprofit economic companies replacing former public benefit companies not only determine the revenues of the whole nonprofit sector in their operations, their work goes beyond this, as most of them are engaged in socially marginalized, disadvantaged, or even disabled people, and can do other work to improve employability and employment. The aim of my study was to process the latest statistical database of the nonprofit sector issued by the KSH in order to determine the role of nonprofit economic companies in employment, by appying secondary analysis.

Process Innovation Tools and Strategies in Production Management
148-162Views:411The method of process innovation helps to recognize the opportunities in production processes that represent clear competitive advantage. Using it, up to 30% change is available in increasing productivity and in the reducing of costs, stocks, and lead times. There is no need for complicated methods in the process development. The power of logical, simple tools relies on the fact that everyone can learn, understand, apply them and give quick feedback about their operation. Significant changes have been made in today's possibilities of designing and operating production systems. The emergence of cyber physical systems, the opportunities offered by big data, and the "Internet of Things" (Internet of Things) have shown strong research potential for more efficient logistics and manufacturing systems. The potential of network co-operation, information gathered from tracing materials in production and communication between machines provide a wide-range of optimization opportunities for manufacturing processes. The toolkit presented in the research cannot only be used in direct production; almost all parts of the value creation process can be broken down into routine actions, so the causes of the problems can be analyzed and the development of the process’ parts can be easier implemented.

Economic Analysis of Thermal Insulation Systems
1-5Views:166One of today's most important problem of inadequate energy management. In Hungary, most of the buildings considered to be outdated in the building materials used and taking into account the construction technology. A significant part of the heat energy used for heating purposes before leaving the environment through the building envelope elements used in time. In our study we investigate whether an average house how much energy you can save the facade walls with insulation.

Gamification in Programming - a Short Introductory Session in Programming with Online Games
16-22Views:326Nowadays computer science is a diversified discipline with a wide range of interdisciplinary applications. Because of that, teachers at primary or high schools unavoidably face the following problem: What are the most useful fields, topics and applications of computer science and programming, and how can we teach them to be motivating enough for a student from the Z generation. In this paper we give a possible answer for the question above by presenting a short introductory session in programming for students in primary and high school. Our primary aim with the above session is to motivate students to continue their studies in engineering higher education. We also present our experiences about two experimental classes here.

Geotechnical Risks and its Influence on Investment in the Case of Vacant Locus
298-312Views:181At a building on vacant locus a significant amount of geotechnical risk can be arisen. In the case of arise of risks the technical content of the investment is amended, the time requirement as well as the cost of the investment is increasing. In the paper a review on the geotechnical risks, on their effects, as well as on the management of risks is given.

The Role of Renewable Energy Sources in Energy Production and Use
678-688Views:396The role of renewable energies in energy management is growing both in the European Union and in Hungary. The use of renewable energy sources is already quite large (transport, heating, lighting, etc.) and it is advisable to deal with these energy sources in the year 2020. The use of energy from renewable sources can reduce greenhouse gas emissions and reduce dependency on the continuously problematic oil and gas market. A review of energy data over the last 10 years shows that renewable energy sources are playing an increasingly important role in the European Union. I support this finding by the fact that the share of energy from renewable sources in gross energy consumption has almost doubled in the last few years.

Perceived Barriers to Youth Entrepreneurship in Pakistan and Hungary
382-391Views:230Entrepreneurship brings enormous benefits. It generates employment and helps in social and economic development. Ventures created through the youth entrepreneurship have enormous benefits. They generate employment, reduce poverty and unequitable distribution of wealth. These ventures do also help in social, economic and technological development. However, the youth faces several barriers to entrepreneurship. This study explores the personal & psychological, family related, institutional & regulatory, cultural & social, financial and market & knowledge barriers faced by the youth of Hungary and Pakistan. Qualitative research methodology was applied. Interviews at micro and meso levels were conducted from the young entrepreneurs and university professors of Pakistan and Hungary. Results indicate that Pakistan and Hungary have almost similar levels of Personal & Psychological barriers, however, the fear of failure is higher in Hungary than in Pakistan. Family related, cultural & social and market & knowledge barriers are higher in Pakistan for the youth entrepreneurship than Hungary. Institutional & regulatory and financial barriers are at medium levels in Pakistan. For Hungary, these are at low levels. The study has important implications for researchers, academicians, policy makers and for the young aspiring entrepreneurs.
