How the Influence of Psychoactive Substances Impacts the Road Safety of Drivers †

I. Lakatos Emese Sánta Gábor Patocskai Petra Szűcs

Publication Name: Engineering Proceedings

Publication Date: 2025-01-01

Volume: 113

Issue: 1

Page Range: Unknown

Description:

In Hungary, the consumption of any alcoholic beverage before driving is illegal. A person is considered drunk if they have a blood alcohol concentration of 0.5 g per liter or more. The situation regarding drug use is also disappointing. This research analyses these effects on transport and their “outcome” by evaluating analyses based on police data, driver training data, and experimental data. The research aims to further raise awareness of the public health importance of this problem through a case–control study. Descriptive and correlational, statistical calculations were performed with a significance value of p < 0.05. Between 2019 and 2023, there were 10–13.000 drunk driving offenses and 1.000–1.300 drunk-driving accidents on the roads each year, most of which occurred in the capital and caused minor injuries. The results will be used to discover synergies to improve road safety.

Dynamic Modeling Possibilities of Embedded Rail Structures

Szabolcs Fischer Zoltán Major Attila Németh Vivien Jóvér Nándor Liegner

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2025-01-01

Volume: 22

Issue: 4

Page Range: 29-43

Description:

In Hungarian design practice, the Zimmermann-Eisenmann quasi-static design method is employed to dimension track structures with embedded rails. This method determines the mean values of deformations and stresses using an infinitely long elastically embedded beam as the static frame. After establishing these mean values, the effects of track condition and speed are considered through Eisenmann multiplication, enabling the definition of design values. Conversely, international practices include methods that calculate deformations and stresses based on dynamic models incorporating viscoelastic embedding, directly accounting for speed but not dynamic effects due to track characteristics. This paper presents a solution to the dynamic problem, extending it to studying rotating frames beyond the commonly considered uniaxial solution. Each factor's effect is separately analyzed for track structures with embedded rail tracks, leading to a recommendation for the value of the "load multiplication factor".

Issue: 3

Page Range: 278-294

Description:

In this paper we investigate the effect of family background and institution background on career choice intentions of Hungarian students based on the database of GUESSS 2011 international survey. Models, attitudes, morals from home often exert significant influence on children's walk of life. Our research focuses on the strength of familial and institutional effects on students' career choice expectations. The novelty of our study is that we analyse the factors in the whole sample and in the following parts of sample: students with and without family business background. In the first part of this study we show the former researches conducted in this topic, after it we show the career intentions of the higher education students in Hungary. The main part of our study is the analyses of the influential factors of career choice expectations of Hungarian students.

Hypergraph Formalism for Fuzzy Signature-Based Robot Environment Representation

Csaba Hajdu Ahmet Mehmet Karadeniz Danuta Rutkowska Ĺaszĺo T. Ḱoczy

Publication Name: Journal of Artificial Intelligence and Soft Computing Research

Publication Date: 2026-01-01

Volume: 16

Issue: 1

Page Range: 91-100

Description:

This paper introduces a pioneering approach to robot environment representation by integrating a novel hypergraph-based method for modeling fuzzy signatures with a quadtree-like structure for obstacle detection. By structuring fuzzy signatures through hypergraphs, we establish a robust framework that not only streamlines information representation but also simplifies the aggregation-based decision-making process. This synergy is applied to the domain of mobile robotics, where accurate and efficient environment representation is essential. Utilizing a quadtree-like structure for data organization, our technique systematically evaluates feature points against a set of fuzzy operations, determining the significance of obstacles and reconstructing the environmental model through the traversal of the quadtree-like structure. Furthermore, the hypergraph-based formalism sets the stage for a future transition to a tensor-based representation of fuzzy signatures, as envisioned in future work.

Traditional or alternative wine packaging: a study of consumer choices and perceptions

Boglárka Eisingerné Balassa Agnes Csiba-Herczeg Réka Koteczki

Publication Name: International Journal of Urban Sciences

Publication Date: 2025-01-01

Volume: 29

Issue: 1

Page Range: 314-331

Description:

Sustainability concerns in the wine sector have resulted in alternative types of wine packaging to traditional glass packaging. This article examines the impact of cultural heritage and environmental awareness on consumer behaviour and purchasing decisions in relation to wine packaging. To investigate this, a wine tasting experiment was carried out on a sample of 211 people in the city of Pécs, in Hungary, to assess consumers’ perceptions, taste perceptions and purchase propensity for 7 types of wine packaging. In order to measure the effect of each type of packaging, the same wine was poured into the same types of packaging. The aim of the experiment was to identify consumers’ attitudes towards traditional packaging and their preferences for alternative options. The results were analysed using factor analysis to identify 2 factor groups for each pack, which were validated using Bartlett's Test and Chi-squared Test. The results show that packaging style and traditionality have a significant impact on consumer preferences, especially for alternatives such as bag-in-box or pouch, which are completely different from the traditional glass bottle. In the case of PET bottles, the packaging itself has a strong explanatory power, which may be explained by its similarity in form to the glass bottle. The novelty of this research lies in the fact that with the help of the we were able to measure the effect of different wine packaging, alongside the role of cultural traditions. Based on the results, it is proposed that wine industry stakeholders should raise consumer awareness of the benefits of environmentally friendly packaging alternatives and take measures to reduce the environmental impact of traditional glass bottles.

Toward sustainable development: Revealing the dynamic impacts of the belt and road initiative on energy transition

Gagan Deep Sharma Arshian Sharif Muhammad Zubair Chishti Qi Xu

Publication Name: Sustainable Development

Publication Date: 2024-12-01

Volume: 32

Issue: 6

Page Range: 7069-7095

Description:

This article investigates the influence of the belt and road initiative (BRI) on energy transition within the context of sustainable development goal (SDG) 7. The study utilizes daily data from May 3, 2017, to June 30, 2023, and deploys advanced econometric methods like heatmap-based QVAR, cross-quantilogram, and recursive time-varying methods. The findings determine that BRI can significantly foster the global energy transition process. Further, the Paris Agreement (PA) and green finance (GF) support the energy transition system by showing positive effects. In contrast, geopolitical risk (GPR) introduces disruptive elements that impede green energy production. Notably, the amalgamation of GF, PA, and BRI showcases the potential to not only facilitate SDG 7 but also contribute substantially to SDGs 8 and 13. Based on the above findings, the study suggests fostering synergies and collaboration between GF, PA, and BRI to maximize their combined impact on the energy transition, which may decrease the influence of GPR.

Blockchain Technology in the Food Industry: A Review of Potentials, Challenges and Future Research Directions

Horst Treiblmaier Suhaiza Zailani John G. Keogh Abderahman Rejeb Karim Rejeb

Publication Name: Logistics

Publication Date: 2020-12-01

Volume: 4

Issue: 4

Page Range: Unknown

Description:

Blockchain technology has emerged as a promising technology with far-reaching implications for the food industry. The combination of immutability, enhanced visibility, transparency and data integrity provides numerous benefits that improve trust in extended food supply chains (FSCs). Blockchain can enhance traceability, enable more efficient recall and aids in risk reduction of counterfeits and other forms of illicit trade. Moreover, blockchain can enhance the integrity of credence claims such as sustainably sourced, organic or faith-based claims such as kosher or halal by integrating the authoritative source of the claim (e.g., the certification body or certification owner) into the blockchain to verify the claim integrity and reassure business customers and end consumers. Despite the promises and market hype, a comprehensive overview of the potential benefits and challenges of blockchain in FSCs is still missing. To bridge this knowledge gap, we present the findings from a systematic review and bibliometric analysis of sixty-one (61) journal articles and synthesize existing research. The main benefits of blockchain technology in FCSs are improved food traceability, enhanced collaboration, operational efficiencies and streamlined food trading processes. Potential challenges include technical, organizational and regulatory issues. We discuss the theoretical and practical implications of our research and present several ideas for future research.

Towards a quadtree based approach to learn local plans in robotic motion planning

Áron Ballagi Csaba Hajdu

Publication Name: Gpmc 2020 2nd IEEE International Conference on Gridding and Polytope Based Modeling and Control Proceedings

Publication Date: 2020-11-19

Volume: Unknown

Issue: Unknown

Page Range: 25-30

Description:

In this paper, a novel approach to the local planning of mobile robots and autonomous vehicles is discussed. This paper introduces a motion planning architecture utilizing both a conventional (Hybrid A∗) and a learning-based planner, inspired by the recent results of reinforcement learning. The presented approach relies on a grid-based representation of the environment which is simultaneously used for planning and learning of such trajectories. The representation grid is derived from a quadtree representation of the environment and the definition is extended with convex polytopic description, to produce grid-based and Voronoi diagrams. The paper also discusses the possible integration of more sophisticated soft-computing-based control, like TP-model transformation as a basis for the heuristics used by motion planning components.
