Development opportunities for mobile and ICT learning in teacher education

Szilvia Petzné Tóth Bernadett Éva Pápai József Reider

Publication Name: Annales Mathematicae Et Informaticae

Publication Date: 2023-01-01

Volume: 59

Issue: Unknown

Page Range: 131-145

Description:

Learning is nowadays a continuous intellectual readiness to be able to cope with the current needs of the world of work. Students’ knowledge must be adapted accordingly and they must be capable of continuous development throughout their lives [8]. Changes in teaching-learning habits have already been observed at the beginning of the 21st century and those involved in education need to adapt to these changes with the appropriate transition to digital education what is more important today than ever be-fore. We asked our teacher-candidate students in an online questionnaire at the beginning and at the end of the “Teaching Methods in Mathematics” course. Our non-representative survey provided valuable data for course de-velopment. The aim of the survey was to find out students’ perceptions of the methods and tools they had learned in education. In the questionnaire at the beginning of the semester, we inquired our students about the types of work and methods they were familiar with, and then they gave their opinions about the different ICT tools, educational programmes and applications and how they were used. At the end of the semester, we interwieved them again whether they still held similar views on the subject or they had managed to change their views during the course.

Validation of finite element connection modeling by comparison of experimental and virtual power injection methods

Dániel Feszty Marcell Treszkai David Sipos

Publication Name: Journal of Vibroengineering

Publication Date: 2023-01-01

Volume: 25

Issue: 1

Page Range: 209-225

Description:

There are several ways to obtain the matrix of damping loss factors and coupling loss factors for Statistical Energy Analysis. The most recent approach is Virtual SEA, where the Power Injection Method is performed virtually on a finite element model. In order to validate this approach, the most common connection types are investigated in this paper through an L-junction of two coupled steel plates. Virtual SEA and experimental Power Injection Method results are compared in a bent, line welded, superglued and spotwelded variants. The respective finite element connection representation is also validated during the comparison. It was found that with the correct simulation setup, Virtual SEA provides good agreement with the experimental results. In case of the spotwelded variants, further investigations were necessary regarding the parameters of the connection. The influence of these parameters was evaluated and the greatest source of deviations in the results is found.

Evaluating Fuel Consumption Rates Based on Rising Travel Demands Generated by Autonomous Vehicles

Balazs Horvath Dilshad Mohammed

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 553-558

Description:

Autonomous Vehicles (AVs) are anticipated to revolutionize the transportation sector by enhancing mobility and efficiency. However, the rise in travel demand resulting from increased accessibility and convenience may counterbalance the potential fuel savings associated with AVs. For this reason, this study examines the relationship between travel demand and fuel consumption, considering factors such as travel time, number of trips, and travel patterns. Through a combination of theoretical analysis and empirical data, the research aims to quantify the net effect of travel demand increment under varying demand scenarios using AVs on fuel consumption. The results showed that with the convenience of AVs, people may be more willing to tolerate longer commutes. This has led to an increase in Vehicle Hours Travelled, which directly translated to higher fuel consumption. These findings provide valuable insights for policymakers and stakeholders in designing sustainable transportation strategies and optimizing the energy efficiency of AV-based mobility systems.

The impact of unpredictable resource prices and equity volatility in advanced and emerging economies: An econometric and machine learning approach

Laszlo Vasa Ashutosh Kolte Jewel Kumar Roy

Publication Name: Resources Policy

Publication Date: 2023-01-01

Volume: 80

Issue: Unknown

Page Range: Unknown

Description:

Global stock markets are incredibly unpredictable. Resource prices have a significant market impact on varying securities. With the use of cutting-edge technology like artificial intelligence, analysts and researchers are employing various machine learning techniques and econometrics methodologies to anticipate stock price trends in order to better comprehend stock market volatility. Volatility is the degree of variation in a time sequence of market rates. Stock market equity returns depend on the business output where the investor has trust in high and low equity. This research explores the interaction between industrialized and developing economies' market volatility relationships between 2000 and 2020 as well as the aforementioned impacts taking place on developing financial prudence worldwide. The aim of the study is to integrate an appropriate GARCH framework to estimate the uncertainty dependent on market conditions in the European Union, the Pacific, South America, Latin America, East Asia, West Asia and South Asia stock return indices. The Generalized Auto-Regressive Conditional Heteroscedasticity method is used for analyzing the effect of updates from the USA that influences the returns of S&P 500 globally as well as European Union, Pacific, South American, Latin American, East Asian, West Asian and South Asian indices returns. For capital markets of the world, there is a significant gap in equity return uncertainty. Such results have major effects on investors looking to diversify their portfolios. For international and domestic institutional shareholders, this paper is significant. The impact of international institutional investors' investments and effects of the growth of the equity market return may be omitted as the analysis is restricted exclusively to the European Union, the Pacific, South America, Latin America, East Asia, West Asia, and South Asia.

Integration of Sustainability into the operation of businesses through Human Resource Management Education

Attila Pongracz Szabolcs Rákosi

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 91-96

Description:

This research focuses on a hardly studied dimension of Sustainability, on its aspects of Human Resource Management (HRM). The examination of the topic is justified by the fact that the emergence of Sustainable Human Resources Management (SHRM) as one of today's modern, innovative HR approaches has not yet been examined in Hungary. Thus, the research fills a gap. The study aims to investigate how and to what extent Sustainability is implemented in the HRM practices of businesses of different sizes in the Northwest-Hungarian Economic Development Zone. The questionnaire survey forming the basis of this study was carried out by interviewing managers and HR professionals of the companies. The results indicate that Sustainability appears in extremely diverse ways and degrees in the examined organizations. The vast majority of them still consider Sustainability to be a primarily environmental issue. During their operations, the companies highlight the economic and environmental aspects of Sustainability and, despite the labor shortage, do not place a significant emphasis on Sustainability in the areas of Staffing, Compensation Management, and Staff Development. As a result of this research, Széchenyi István University ensures, through the development of HR training, that future professionals can develop and operate the model of SHRM in practice by taking into account new aspects and applying a complex approach. The results of the study will not only provide new value for the academic sphere but can also contribute to more efficient and fair operation of businesses.

Lézerszkennerrel felmért közlekedési csomópontok láthatósági vizsgálata referenciasík segítségével

Csaba Koren Zsófia Magyari

Publication Name: Geodezia Es Kartografia

Publication Date: 2023-01-01

Volume: 75

Issue: 1

Page Range: 16-23

Description:

According to road design guidelines, unsignalized intersections should have certain free sight fields to ensure that vehicles approaching from different directions see each other. However, in many cases these sight fields include some obstacles which cause safety concerns. The identification of these obstacles and the planning of appropriate interventions would improve safety. In this article, we present an analysis method suitable for visibility investigation based on a laser scanner survey. We review the methods developed in recent years to select the visible and hidden points of the point cloud. Based on the presented results, we developed a procedure that is consistent with the concept of sight distance used in the field of road design. The survey was taken from an observation point of the drivers on the minor road and the sightlines were projected onto a reference plane along the major road, considering the required sight distance. The projected results appeared as "shadows" from the visibility obstacles on the reference plane. The visibility difficulties detected can be used to decide the appropriate actions to improve the safety of the intersection.

Kata D. Jankovits Julia Szoke

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 223-228

Description:

Scientists from various fields have long examined the factors contributing to sustainable development in Africa. The paper investigates the topic of sustainable development focusing on a very special part of Africa, the Sahel region, which is an ecoclimatic and biogeographic region of Africa facing many challenges. Consequently, the secondary research to be presented in this paper aims to review some projects and actions taken by various organizations, like the United Nations and the African Union, that stimulate sustainable development in the Sahel region. Accordingly, it focuses on a few of those projects and actions, which, on the one hand, enable sustainable agriculture, the reduction of malnutrition and food insecurity, and water usage combined with latrine construction, and which, on the other hand, enhance natural resource management and increasing resilience to climate change. The paper concludes with some remarks regarding the efficacy of these projects and actions from the viewpoint of sustainability, and finds that even though these projects and actions are of significance, there is still a long road ahead to reach sustainable development in the Sahel region.

Economic empowerment as a result of achieving SDGs with resource access: A comparative research between Gaza Strip and Hungary

Laszlo Vasa Nassar Samia Zsuzsanna Naárné Tóth

Publication Name: Journal of International Studies

Publication Date: 2023-01-01

Volume: 16

Issue: 2

Page Range: 9-33

Description:

Donors, development agencies, and international non-governmental organizations are currently shaping a large part of the development and humanitarian agenda of sustainable developmen, especially regarding the first and second Sustainable Development Goals (SDGs) related to ending poverty and hunger worldwide. Thus, an increasing number of development interventions are aimed at protecting the planet and ensuring prosperity for everyone by strengthening the resilience of vulnerable households and communities. The research implemented a quantitative methodology approach that relied on distributing a survey based on the research variables. Data were collected in both the Gaza Strip and Hungary using google forms over a sample of 700 respondents, however, only 616 respondents filled out the survey. The collected data were analyzed using the SPSS statistical tool to research the impact of no poverty and zero hunger on economic empowerment and how resource access mediates this relationship. The research results were reported 9 using descriptive and regression analysis, while mediation analysis was based on the method of Barron and Kenney. Most of the world's poor live in rural regions, and if we want to help them, we need to concentrate on developing agriculture in a modern and sustainable manner to create employment, increase farmers' incomes and consumption, and decrease food costs. Governments need to learn more about their strengths and challenges to aid communities in expanding. While primary agriculture may provide a viable income for those living in different regions, there is always the potential for diversification. Recognizing and capitalizing on other areas' variety or growth might significantly lower poverty levels. There is an urgent need to address the issue of food security, which requires a renewed commitment from governments, farmers, national policymakers, and international donors.

FAMILY-FRIENDLY WORKING ARRANGEMENTS IN THE V4 COUNTRIES

Anna Pátkai Bende

Publication Name: Journal of Community Positive Practices

Publication Date: 2023-01-01

Volume: 23

Issue: 3

Page Range: 99-111

Description:

The study examines the countries of the Visegrad Group from the point of view of how widespread family-friendly working arrangements are in their labor market. The paper highlights that the labor market of the V4 countries in the past decade was characterized by continuous rise of employment rates. As the role of women in the labor market increases, employees have to face constant challenges in reconciling their professional and family obligations. However, flexible working arrangements that could help employees combine work and private life, are still not widespread in the V4 countries. The study primarily examines the proportion of part-time employees and remote workers of the Visegrad countries in the light of Eurostat data. The paper emphasizes the role of the governments, companies, and civil society in creating ideal workplaces for employees with family.
