Volume: Unknown

Issue: Unknown

Page Range: 1305-1312

Description:

In the paper we discuss the course history, the basic goals and principles defined at the beginning, and we talk about its methodology. For the “Complex project” course the main parts of the lecturer's job are the detailed preparation of the project tender, the operative support of the students' work, and they also have to perform the mid-semester and end-of-semester evaluations. Continous progress is controlled by milestones laid out throughout the program. The effectiveness of the “Complex project” can be determined based on the previous years, and the future possibilities will also be examined. Besides elevating the level of education from the students' perspective, at the same time it also improves the lecturers' competences.

Description:

Every society has its own characteristics, shaped from time to time by the various innovative, disruptive, but in any case, dynamically changing mechanisms that affect it most. In today's society, technological innovation plays a major role in the development of individuals and their abilities. Education is the most typical and obvious arena for shaping, developing, and preparing for the challenges of the future. As in the leading sectors, in the world of education, rapid responses and immediate reactions to change significantly increase the ability to achieve and maintain success and thus marketability. As a sector responsible for developing the competences of individuals, building knowledge and training professionals, education should seek to keep pace with trends and break with traditional approaches and methods, so that, in addition to incorporating technological developments, a renewed approach to organizational development and methodology is an important means of achieving the desired success and effectiveness. In the course of our work, we provide a summary insight into the project work of student groups who require up-to-date IT skills, use advanced IT tools, plan, and implement their web development workflows supported by database management, front-end planning and design, and back-end programming with a project management approach according to the latest trends, interpreting the advantages and disadvantages of working methods for success.

A global framework for integrating public health into wellbeing: why a public wellbeing system is needed

Attila Tanyi Mária Arapovics László L. Lippai Klára Tarkó Zsófia Kollányi Mária Arapovics József Vitrai

Publication Name: Frontiers in Public Health

Page Range: Unknown

Description:

There is a growing focus on public health initiatives that prioritize wellbeing. The main question of our study is whether this, in its current form, can really represent a new response to the challenges of previous strategies, or whether there is a greater chance that it will essentially reproduce the problems associated with the paradoxical situation of public health. Based on a review, analysis and evaluation of the literature on wellbeing in public health, we outlined the foundations of a new meta-theory of wellbeing and a possibility for its social application. In our view, wellbeing is seen as a social representation of a combination of positive and negative freedom of choice concerning the quality of everyday life, used in a positioning process involving both individual and collective aspects. Health is a particular aspect of the social representation and positioning of wellbeing, which encompasses aspects of the physical, psychological, social and spiritual functioning of individuals. The wellbeing meta-theory also opens up the possibility for more effective solutions to the social challenges related to wellbeing and salutogenetic health. It underscores the importance of the need for a dedicated social subsystem where the goals and organizational culture of the organizations involved are focused on wellbeing and health promotion. In our study, we consider this to be the Public Wellbeing System (PWS). Our conclusion is that the development and operation of a new set of institutions—the Public Wellbeing System (PWS)—based on the co-production of services that meet the needs and demands of society, and dedicated to the promotion of wellbeing, may provide an opportunity to overcome the public health paradox.

Sustainable Land Production Methods: The Spatiotemporal Evolution, Determinants, and Future Implications of Grain Crop Production Agglomeration in China Under Resource Constraints

Irum Shahzadi Cheng Li Feng Wu Mingxing Zheng Zhaocai Cui Irum Shahzadi

Publication Name: Land Degradation and Development

Publication Date: 2026-04-30

Volume: 37

Issue: 7

Page Range: 2671-2684

Description:

Amid the backdrop of increasing global extreme weather events and tightening resource constraints on grain crop production. China, as the world's most populous country, faces persistent challenges to grain security. On one hand, grain crop production agglomeration (GCPA) can effectively address grain security challenges by optimizing the spatial layout of agricultural production. On the other hand, it can enhance the efficiency of resource utilization in grain production, thereby ensuring the stability and sustainability of the national grain supply. The study uses 1980 as the baseline and employs a range of analytical methods, including the spatial Gini coefficient, industrial concentration, global Moran's I, and LISA agglomeration map, to investigate the temporal–spatial variation trends and characteristics of GCPA in China from 2000 to 2020. Subsequently, a spatial Durbin model with time and space fixed effects is applied to identify the key factors influencing changes in the level of GCPA. The findings are further contextualized to explore opportunities for leveraging GCPA to promote sustainable land resource development. The results reveal that, from temporal variation trends in GCPA, the overall level of GCPA in China has exhibited a steady upward trend. From temporal variation characteristics in GCPA, the provinces contributing to GCPA have gradually concentrated in Heilongjiang, Henan, Shandong, and Anhui, demonstrating significant provincial convergence. From spatial variation trends in GCPA, while the global Moran's I of GCPA experienced brief declines in 2009 and 2018, it has generally shown a steadily increasing trend, reflecting strong spatial dependence. From spatial variation characteristics in GCPA, the spatial distribution of GCPA exhibits polarization, with provinces transitioning between high-high (H-H) and low-low (L-L) agglomeration clusters. This indicates that regions with lower grain production capacity are likely to experience further declines, regardless of their proximity to high-production regions. The analysis identifies agricultural transportation infrastructure as the most critical factor promoting GCPA. Conversely, excessive use of chemical fertilizers and labor inputs in grain crop production are found to hinder GCPA. Based on these findings, the study recommends enhancing agricultural transportation infrastructure and improving the efficiency of traditional agricultural inputs to elevate GCPA levels, thereby fostering sustainable land resource development.

On Preservation of Positivity in Some Finite Element Methods for the Heat Equation

Panagiotis Chatzipantelidis Vidar Thomée Zoltán Horváth

Publication Name: Computational Methods in Applied Mathematics

Publication Date: 2015-10-01

Volume: 15

Issue: 4

Page Range: 417-437

Description:

We consider the initial boundary value problem for the homogeneous heat equation, with homogeneous Dirichlet boundary conditions. By the maximum principle the solution is nonnegative for positive time if the initial data are nonnegative. We complement in a number of ways earlier studies of the possible extension of this fact to spatially semidiscrete and fully discrete piecewise linear finite element discretizations, based on the standard Galerkin method, the lumped mass method, and the finite volume element method. We also provide numerical examples that illustrate our findings.

A modified model of the willingness to pay for functional foods

Sándor Kovács Zoltán Szakály Károly Pető Péter Huszka Marietta Kiss

Publication Name: Appetite

Publication Date: 2019-07-01

Volume: 138

Issue: Unknown

Page Range: 94-101

Description:

The aim of this research was to develop a modified version of the Munene model summarizing the factors influencing willingness to pay for functional foods, adjusted to the Hungarian population. The questionnaire survey was conducted in 2014 in Hungary on a sample of 500 individuals, representative for gender, age, settlement type and region. Building blocks of the Munene model were examined and tested with a Latent Variable Path Analysis with the Partial Least Squares (LVPLS) model. According to the results, the strongest relationship in the modified model was identified between attitudes towards, and beliefs about, the attributes of functional foods, i.e. the more consumers believe in the health protecting effect of functional foods, the more positive their attitudes towards those foods, and the more they are willing to pay a premium for them. The highest explanatory power in the model was attributed to the attitudes towards functional foods, followed by beliefs about the attributes of functional foods, and then by consumer demographics. The modification of the original Munene model based on a Hungarian sample contributes to an examination of its usability and provides an example of how it can fit to another culture. Moreover, a comprehensive model including factors influencing WTP has not yet been developed among Hungarian consumers.

Analyzing the Potential Impacts of the Speed Compliance Behavior of Autonomous Vehicles †

Richárd Horváth Balázs Horváth Attila Borsos Viktor Nagy

Publication Name: Engineering Proceedings

Publication Date: 2024-01-01

Volume: 79

Issue: 1

Page Range: Unknown

Description:

Many researchers argue that autonomous vehicles (AV) will create a safer and more efficient transport infrastructure. However, some studies have drawn attention to potential problems in relation to how AVs and human-driven vehicles will co-exist. We investigated the effect of speed compliance behavior of AVs on an urban two-lane road section with alternating speed limits of 50 and 30 km/h. A Vissim microsimulation model was used where we gradually increased the traffic volume and the market penetration rate (MPR) of AVs. We found that under low traffic flow conditions the increase in MPR will lead to a decrease in the average speed and worsening of the average travel time. Under medium and, specifically, under saturated conditions, a high share of AVs can bring stability to the system. They can also significantly improve the speed compliance rate.

Horst Treiblmaier John G. Keogh Abderahman Rejeb

Publication Name: Future Internet

Publication Date: 2019-07-01

Volume: 11

Issue: 7

Page Range: Unknown

Description:

Modern supply chains have evolved into highly complex value networks and turned into a vital source of competitive advantage. However, it has become increasingly challenging to verify the source of raw materials and maintain visibility of products and merchandise while they are moving through the value chain network. The application of the Internet of Things (IoT) can help companies to observe, track, and monitor products, activities, and processes within their respective value chain networks. Other applications of IoT include product monitoring to optimize operations in warehousing, manufacturing, and transportation. In combination with IoT, Blockchain technology can enable a broad range of different application scenarios to enhance value chain transparency and to increase B2B trust. When combined, IoT and Blockchain technology have the potential to increase the effectiveness and efficiency of modern supply chains. The contribution of this paper is twofold. First, we illustrate how the deployment of Blockchain technology in combination with IoT infrastructure can streamline and benefit modern supply chains and enhance value chain networks. Second, we derive six research propositions outlining how Blockchain technology can impact key features of the IoT (i.e., scalability, security, immutability and auditing, information flows, traceability and interoperability, quality) and thus lay the foundation for future research projects.

Description:

Some cities in China are facing challenges due to population loss while also attempting to address energy conservation and emissions reduction. Although urban shrinkage can relieve pressure from energy consumption demands, such as water, electricity and gas, does it improve urban energy efficiency? This study attempts to answer this question. Based on Point of Interest (POI) big data and Global Human Settlement Layer (GHSL) raster data, this study identifies urban shrinkage from the coupling perspective of administrative and economic boundaries. It also examines the impact of urban shrinkage on energy efficiency. The results suggest that Chinese counties’ overall energy efficiency is experiencing a four-stage “decline-rise-decline-rise” trend, and the urban shrinkage of Chinese counties exists in three major areas: the Northeast, the Southwest, and the Centre. Compared to non-shrinking cities, urban shrinkage has a significant negative impact on improving energy efficiency. This impact exhibits significant heterogeneity. Specifically, compared with mature resource cities and cities in Western China, regenerative cities, non-resource cities and cities in Central China have less impact on energy efficiency. In addition, urban shrinkage may impede energy efficiency improvement by hindering industrial structure transformation and upgrading, energy-saving technology innovation, and financial development. Clarifying the relationship between urban shrinkage and energy efficiency is helpful for shrinking cities to change their development strategies, which is critical for sustainable development.
