Description:

Sustainable transportation systems are becoming an increasingly important issue around the world, especially with the advancement of urbanisation. Autonomous vehicles and ride-sharing services represent innovative mobility solutions that can improve not only the efficiency of transportation but also its environmental sustainability. The aim of this study is to examine Hungarian consumers’ attitudes toward ride-sharing and their acceptance of AVs, with a focus on whether there is a link between the two phenomena. The research is based on a nationally representative sample of 2000 respondents. Correlation analyses were performed based on the dimensions of technology acceptance models. Based on the results, a significant positive correlation can be demonstrated between the willingness to use ride-sharing services in the future and the openness towards AVs. Perceived usefulness and social influence showed the strongest relationship with intention of usage. The results contribute to the social acceptance of autonomous technologies and sustainable transport in Hungary.

Investigation of Energy-Efficient UAV Control: Analysis of PID and MPC Performance †

Miklós Kuczmann Áron Ballagi Barnabás Kiss

Publication Name: Engineering Proceedings

Publication Date: 2025-01-01

Volume: 113

Issue: 1

Page Range: Unknown

Description:

Unmanned Aerial Vehicles are being applied in an increasing number of fields; however, their autonomous operation is associated with significant regulatory challenges. In this study, the performance of a PID and a Model Predictive Controller is compared based on the transfer function of the BLDC motor of a quadcopter using MATLAB simulations in the presence of white noise. The simulation results are used as reference values for measurements conducted on a cost-effective, custom-developed prototype drone. The prototype has been designed for short-duration hovering, allowing for an initial evaluation, but a more thorough analysis requires prolonged hovering tests to be carried out in an industrial environment. Based on the results, a recommendation is formulated for improving the PID controller to achieve performance closer to that of the MPC. The research is aimed at enhancing the energy efficiency of UAV systems and optimizing battery capacity, enabling longer autonomous flight time and more reliable control.

Dilemmas of Child Protection in Hungary During the Austro-Hungarian Monarchy: Addressing the Issue of Morally Abandoned Children

Enikő Kovács-Szépvölgyi

Publication Name: Journal on European History of Law

Publication Date: 2025-01-01

Volume: 16

Issue: 2

Page Range: 94-100

Description:

Following the Austro-Hungarian Compromise (1867), Hungary underwent significant legal modernization, which extended to the regulation of endangered children. Within the evolving framework of state-led child protection, administrative and judicial branches constituted the core mechanismsaimed at safeguarding vulnerable minors. In the case of morally abandoned, delinquent, or at-risk children – those operating on the fringes of petty criminality – the state sought appropriate interventions, alternating between administrative and judicial approaches. The placement of materially abandoned children in state-run children’s shelters became possible under Decree No. 60.000 issued by the Ministry of the Interior in1907, which, according to archival sources, was implemented in practice. The Juvenile Court Act (Act VII of 1913) allowed for the temporaryor permanent removal of children from their original environments through specific measures: temporary decisions for non-punishable children and definitive rulings for juveniles. As a result, morally neglected children came to occupy the intersection of administrative and judicial state-led child protection systems.

Publication Name: Metszet

Publication Date: 2025-01-01

Volume: 16

Issue: 1

Page Range: 8-17

Description:

"The Cube," in Győr, Hungary, appears isolated but is deeply connected to the city's history. Built in 1976, it was integral to the biscuit factory until its 2009 closure. Now, The Cube serves as an anchor within the Győr Science Park, its transformation preserving the original structure while adding an extra layer. This repurposing highlights questions of architectural autonomy and context, as the building's social significance persists despite changing physical surroundings. The Cube's evolution embodies a dialogue between past and future, symbolizing both Győr's industrial heritage and its future as an innovation hub.

Indicators of sustainability in vocational education and training institutions

Márta Konczos Szombathelyi Hajnalka Hatos

Publication Name: International Journal of Innovative Research and Scientific Studies

Publication Date: 2025-01-01

Volume: 8

Issue: 3

Page Range: 1674-1679

Description:

The paper presents the indicators of sustainability in vocational education and training institutions (VET), which define the tasks of the institutions according to the VET 4.0 strategy and the European Union's objectives. The purpose of this paper is to present and analyze the role of VET in raising awareness of changing economic and social practices and habits that damage the environment in order to ensure the living conditions of present and future generations. The research was conducted among the institutions of a vocational training center, using management interviews, data collection, and document analysis as research methods for examining easily traceable indicators of education in terms of human, social, natural, and economic resources. The main findings show that vocational education and training institutions also play a key role in sustainability. In addition to their educational tasks, another important task is to increase their efficiency and effectiveness in the area of sustainability. The conclusion of the work is that these schools can achieve sustainable development through preventive actions. As a practical implication, the VET needs to be aware of their energy consumption, their choice of means of transport, and the avoidance and prevention of pollution. They have to implement sustainable operations and education for sustainability both inside and outside of school.

Page Range: 85-90

Description:

Waste management is crucial to achieving global sustainability goals, with the Deposit Refund System (DRS) emerging under the Extended Producer Responsibility (EPR) framework to enhance recycling rates by incentivising consumers to return beverage containers through refundable deposits. In Hungary, large retailers are required to participate in DRS, while small retailers may join voluntarily. This research aims to identify key factors influencing the voluntary participation of small Asian retail stores, focusing on economic, operational, regulatory, and social aspects. Using semi-structured interviews with ten stores in Budapest and Győr, a thematic analysis identified both motivators and barriers to participation. Findings indicate environmental awareness among participants, but low operational capacity, with space constraints, labour demands, and unclear regulations limiting engagement. Financial concerns, particularly equipment and handling costs, were major deterrents, while the potential for increased customer traffic was seen as a benefit. The study highlights the need for targeted financial incentives, infrastructure support, and clear policy communication to increase the inclusion of small retailers in DRS frameworks.

Description:

Quantum calculus, similar to calculus without limits, is the same as ordinary “infinitesimal calculus”. Quantum Hermite–Hadamard-type inequalities, according to quantum calculus, recently discovered improvements within quantum Hermite–Hadamard-type inequalities. New results about the derivatives and integrals identities related to both qm1-derivatives and qm2-integrals will be obtained. This research work is motivated by this fact, so using properties of “generalized higher-order strongly preinvex” and “quasi-preinvex” functions, we drive innovative Quantum Hermite–Hadamard-type inequalities. As applications, new Hermite–Hadamard-type inequalities Hermite–Hadamard qm1-integral and qm2-integral-type inequalities will be obtained. These types of identities are applied to “preinvex functions”. The newly obtained important outcomes are present. The results of these new generalizations are used to assess a variety of mathematical difficulties. These new findings have a huge impact on integrated symmetrical functions and approximations, functions with a symmetric degree. These visions are encouraging new and significant achievements in a wide range of mathematics and engineering disciplines. The generalized strongly “preinvex functions” are the “quasi-preinvex function” studied using “elementary Quantum” Calculus methods.

Description:

Numerous situations occur in engineering practice where I-section members must be designed for a combination of flexure, shear, torsion, and/or axial loadings. Particularly in metal buildings and horizontally curved I-girder bridges, these member types may have variable web depth and stepped cross-section transitions along their length. Design guidance for handling combined loadings on these member types has been limited. Modern software systems that can accurately calculate combined second-order elastic demands and elastic buckling loads for general I-section members in general framing systems are increasingly available. This paper discusses new AISC 360 Chapter F provisions under consideration in the 2027 Specification development cycle. These provisions provide an improved, streamlined calculation of the flexural resistance of general I-section members. The calculations address recent research findings regarding the influence of moment gradient and corresponding web shear. The discussion of the new AISC 360 procedures is followed by a brief presentation of recommended ways to verify a design where the member is also subjected to axial compression and/or torsion based on experiences from European and American practice. The focus of the paper is on the essential concepts.

Description:

Background: Current antivirals for orolabial Herpes simplex virus type 1 (HSV-1) often provide incomplete suppression and limited reactivation control, sustaining recurrent oral lesions and inflammation that compromise oral health. HSV-1 subverts host signaling networks to enhance its replication and trigger inflammation. Among these, the extracellular signal-regulated kinase 1/2 (ERK1/2) and phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) pathways are hijacked to facilitate viral gene expression and cell survival. Objectives: In this study, we employed U0126 [a mitogen-activated protein kinase 1/2 (MEK1/2) inhibitor] and LY294002 [a phosphatidylinositol 3-kinase (PI3K) inhibitor] as targeted pharmacological tools to intercept HSV-1’s exploitation of host keratinocyte signaling. Methods: Human HaCaT keratinocytes were infected with HSV-1 and treated with U0126 or LY294002. Western blotting was used to assess phosphorylation of ERK1/2 and activation of protein kinase B (AKT). MTT assays were performed to evaluate cell viability. Real-time PCR was utilized to quantify viral transcripts (ICP0, ICP4, gB, and gC) and inflammatory cytokines [interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α)]. Confocal microscopy was employed to visualize the intracellular distribution of phosphorylated extracellular signal-regulated kinase 1/2 (p-ERK1/2), phosphorylated activation of protein kinase B (p-AKT), and HSV-1 glycoprotein D (gD). Viral titers were determined using plaque assays. Results: The HSV-1 infection induced a time-dependent increase in phosphorylation of ERK1/2 and AKT, with p-ERK1/2 peaking at 12 h and p-AKT increasing 2.5-fold by 24 h. Cell viability declined from 100% at baseline to 45% at 24-hours post-infection (hpi). Treatment with U0126 and LY294002 reduced p-ERK1/2 and p-AKT levels to 25% and 30% of infected controls, respectively, restoring viability to 82 - 86%. Both inhibitors markedly suppressed viral gene expression (ICP0, ICP4, gB, gC down by 60 - 80%) and inflammatory cytokines (IL-6 and TNF-α reduced by > 50%). Plaque assays showed a strong decline in infectious titers — from 175 plaques per well in untreated infection to 60 and 45 plaques after U0126 and LY294002, respectively. Confocal imaging further revealed diminished nuclear accumulation of p-ERK1/2 and p-AKT, indicating disruption of post-entry signaling critical for viral replication. Conclusions: Targeting host signaling bottlenecks with U0126 and LY294002 offers a dual-pronged antiviral strategy against HSV-1 by dismantling the ERK/AKT axis critical for replication and inflammatory amplification. These findings position MEK1/2 and PI3K as promising therapeutic nodes for managing cutaneous HSV-1 infections. This host-directed dual-pathway inhibition may therefore help reduce recurrent orolabial HSV-1 lesions.
