Description:

The research subject is the deposit-refund system of beverage packaging (PET, glass and aluminium) in Hungary, which is under development. For the success of the planned system, it is important to consider the population’s opinion. Therefore, data from a primary questionnaire survey were used for the analyses. This questionnaire was conducted in 2020 and resulted in an evaluable sample of 20, 430 people. The study aims to answer the following research questions (Q). Q1. Does the reform of the beverage packaging deposit-refund system in Hungary have a raison d’être? Q2. What are the demographic characteristics (gender, type of residence, qualification) of those who would redeem beverage packaging in their households if the state paid for it? Q3. Do the demographic characteristics and/or the environmental attitudes of individuals significantly influence their perceptions of the planned new system, and how strong is the relationship between them? As for the method for answering the research questions, descriptive statistics and relationship analyses (Cramer’s V and Kendall’s tau) were applied to the closed answers. The results show that the analysis of the primary research provides well-determined directions for legislators and decision makers who develop the detailed operating rules of the new system.

Publication Name: 7th IEEE International Conference on Cognitive Infocommunications Coginfocom 2016 Proceedings

Publication Date: 2017-01-03

Volume: Unknown

Issue: Unknown

Page Range: 485-496

Description:

This second part of the paper deals with some of Jung's most important comments, interpretation and hypothesis on depth psychological and general human problems of the transition of the Age of Aquarius and Pisces. At the background in almost all cases Wolfgang Pauli's presence of partly spiritiual, partly inspiratory can be detected. Of particular interest are the following discussions in detail on the Ganymede mythologem, the Greek version of the Aquarian myth and their specific spontaneous depth psychological manifestations.

Direct-to-Device Satellite Communications in the European Union: Spectrum Allocation and Regulatory Pathways Within the ITU Framework

Péter Vári András Lapsánszky Hussein Taha

Publication Name: IEEE Access

Publication Date: 2025-01-01

Volume: 13

Issue: Unknown

Page Range: 190556-190581

Description:

Direct-to-Device (D2D) satellite communications—where standard mobile devices connect directly with satellites—offer a promising solution to extend coverage and improve network resilience. This paper examines the spectrum allocation and regulatory challenges of enabling D2D satellite services in the European Union (EU), situating the analysis within the broader evolution of International Telecommunication Union (ITU) regulatory processes. While anchored in the preparations for the World Radiocommunication Conference 2027 (WRC-27), the study emphasizes that regulatory developments are dynamic and extend beyond a single conference cycle, ensuring long-term relevance for spectrum governance. The paper provides an overview of satellite communication fundamentals and defines key D2D concepts, including Internet of Things (IoT) use cases and differences between terrestrial mobile bands and Mobile-Satellite Service (MSS) bands. The analysis highlights the current EU landscape for MSS spectrum, particularly the 2 GHz S-band, and its upcoming licensing challenges. It contrasts the EU approach with international developments—notably the United States’ new “Supplemental Coverage from Space” framework and the United Kingdom’s satellite-to-mobile integration plans—to draw lessons for spectrum-sharing models. Technical and regulatory challenges for integrating D2D are identified, and potential alternative frequency bands and spectrum-sharing techniques are explored. A policy roadmap is proposed, outlining short-, medium-, and long-term actions for EU policymakers and stakeholders to enable D2D services. The study ultimately supports the formulation of a forward-looking regulatory framework that secures Europe’s role in shaping the future of hybrid satellite-terrestrial connectivity.

Decoupling – shifts in ecological footprint intensity of nations in the last decade

Cecilia Szigeti Daniel Robert Szabo Gergely Toth

Publication Name: Ecological Indicators

Publication Date: 2017-01-01

Volume: 72

Issue: Unknown

Page Range: 111-117

Description:

The ecological price of economic growth is a heavily debated issue, where ideologies often neglect factual information. In this paper, through the relationship of the ecological footprint and GDP, we examine the tendencies of eco-efficiency in the first decade of the 21st century. We conclude that the average ecological footprint intensity of countries have improved significantly in the given period. In 2009, 50 percent less area was needed to produce a unit of GDP. Many countries could reach the so-called strong decoupling − these countries could increase GDP while decreasing the ecological footprint in absolute terms. We also repeated the analysis of a scientific article published in 2004. We managed to update data and identify ecologically positive tendencies. In ten years, the average of the world's ecological footprint intensity has significantly improved, it halved all in all. We found that 90 percent of the countries started to move to the direction of sustainable development. Among the studied 131 countries, 40 experienced strong decoupling (absolute decrease of resource use), in 77 countries weak decoupling occurred (relative decrease of resource use), and there were only 14 countries, where no decoupling could be observed (relative increase of resource use).

Y and Z generations at workplaces

Gabriella Horváth-Csikos Andrea Bencsik Juhász Tímea

Publication Name: Journal of Competitiveness

Publication Date: 2016-09-01

Volume: 8

Issue: 3

Page Range: 90-106

Description:

At present, more and more researches deals with the characteristic features of generation Y and generation Z. As it is about the present and future generations, corporate success and the competitive operation are determined by the behaviour of these generations in the long-run. Researches justifies that there are significant differences between the two generations despite the similarities. These differences appear rather emphasized in the corporate environment when several questions arise at workplaces in the process of cooperation - especially in the field of knowledge-sharing and knowledge transfer-regarding the characteristics of the two generations. Last year, the authors carried out a quantitative research by questionnaires in order to reveal what the managing of these two generations mean for the managers and also what difficulties occur when the two generations cooperate with each other and with elder generations as well. The main question of the research was how to approach the new generations from the view of HR? Although the research cannot be considered representative (410 respondents participated in the survey), it can give a picture about the examined issues. The hypothesis phrased by the authors was justified according to which of the HR activities have to adapt to the requirements of the new generations upon their appearance.

The willingness and preparedness of local governments in Ap Vojvodina/Serbia to grip and use development funds of the European Union

Imre Nagy András Ricz

Publication Name: Deturope

Publication Date: 2017-01-01

Volume: 9

Issue: 2

Page Range: 118-128

Description:

EU funds that are available in Serbia are modest both in volume and number, since Serbia received preaccession status only in 2014. Before that, it was only a potential pre-accession country on the external border of the European Union. From the five components of IPA (2007-2013) Serbia could have utilised only the first two components in the pre-accession process: building of EU institutions (EXCHANGE IIV, Regional Socio-Economic Development Programme) and enhancing cross-border cooperation As a conclusion we can say that although substantial sums were invested from the above mentioned resources into the economy of Vojvodina for its development, the main indicator - the GDP - has been increasing only slightly, while these projects have no effects on decreasing unemployment. In the overall economic situation, unemployment is primarily decreased by emigration, in which Vojvodina Hungarians take part at a rate above the average compared to their headcount, thus decreasing the economic power of the community through emigration.

Description:

Background: ABCB1 is a key ABC efflux transporter modulating the pharmacokinetics of a large percentage of drugs. ABCB1 is also a site of transporter mediated drug-drug interactions (tDDI). It is the transporter most frequently tested for tDDIs both in vitro and in the clinic. Objective: Understanding the limitations of various in vitro and in vivo models, therefore, is crucial. In this review we cover regulatory aspects of ABCB1 mediated drug transport as well as inhibition and the available models and methods. We also discuss protein structure and mechanistic aspects of transport as ABCB1 displays complex kinetics that involves multiple binding sites, potentiation of transport and probe-dependent IC50 values. Results: Permeability of drugs both passive and mediated by transporters is also a covariate that modulates apparent kinetic values. Levels of expression as well as lipid composition of the expression system used in in vitro studies have also been acknowledged as determinates of transporter activity. ABCB1-mediated clinical tDDIs are often complex as multiple transporters as well as metabolic enzymes may play a role. This complexity often masks the role of ABCB1 in tDDIs. Conclusion: It is expected that utilization of in vitro data will further increase with the refinement of simulations. It is also anticipated that transporter humanized preclinical models have a significant impact and utility.

IIoT-Supported Manufacturing-Material-Flow Tracking in a DES-Based Digital-Twin Environment

Szabolcs Fischer Gergő Monek

Publication Name: Infrastructures

Publication Date: 2023-04-01

Volume: 8

Issue: 4

Page Range: Unknown

Description:

Manufacturing processes can be cited as significant research areas when examining infrastructure systems and infrastructure, as they are inextricably linked to both. Examples include automobile manufacturing, the production of traffic signs, etc. Connecting and utilizing Industry 4.0 technologies and processing simulation solutions to address industry challenges, such as process optimization and fault detection, are gaining in popularity. Cyber-physical systems and digital twins connect the physical and cyber worlds to enable intelligent manufacturing capabilities, increased system flexibility, decreased manufacturing-cycle times, and improved quality. This paper presents a solution that improves the synchronization between the real (physical) and simulation (digital) layers, using discrete-event-driven simulations to create more efficient and accurate digital-twin environments. Using a combination of inexpensive commercial microcontrollers and an inertial-measurement-unit sensor to enhance a standard programmable logic controller process, a discrete-event-simulation-based digital layer is updated in real time to produce a live digital twin. The system can accurately identify and track products throughout the production cycle while simultaneously updating the digital twin in real time. Even independently, the algorithm running on the microcontroller can be used to gather the input parameters required for the simulation of production processes. The implemented environment can serve as a suitable testing ground for investigating the practical applicability of digital-twin solutions.
