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.

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 589-594

Description:

The mismatch between land use and road layout has led to high traffic volumes in unsafe conditions in periurban areas. This is also the case in Pathumthai Province, which was selected as a study area, as one of the areas surrounding Bangkok, the megacity of Thailand. For this study, an attempt was made to focus on 4 points of road junctions of multi-lane highways and to observe their longitudinal differences with their speeds. The results showed that traffic volume has a major impact on accident risk, especially at higher traffic volumes and in mixed-traffic situations. The risk is increased by the presence of commercial vehicles mixed with smaller vehicles (e.g. motorcycles), which require sufficient distance between following vehicles. The novelty of this paper is identifying driver behaviours through the use of prototype CCTV technology and distinguishing the role that types of drivers' vehicles play in mitigating risks in different travel patterns, considering the safety aspects of highway design and land use.

Description:

Detection of textual data from scene text images is a very thought-provoking issue in computer graphics and visualization. The challenges of text detection come from the nature of images used to detect text from them. The technology proposed is comprised of three main stages: Blurring, transformation to the frequency domain, and de-blurring in the frequency domain as preprocessing procedures; a proposed hybrid model for text detection using k-means clustering and text bounding boxes is used, and (CNN) framework used to classify into textual and non-textual regions. We used the Stroke Width Technique (SWT) when increasing the value of k by analyzing the width of the strokes in the image and thus reducing the potential textual regions resulting from the MSER, which leads to reducing the time and increasing the accuracy of detection, a convolutional neural network (CNN) algorithm is used to perform a classification of all bounding boxes. For the suggested technique's evaluation, results are collected on three popular datasets, including SVT, IIIT5K, ICDAR 2013, and ICDAR 2015. The datasets for SVT, IIIT5K, ICDAR 2013, and ICDAR 2015 each have classification results of 87.41.

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.

Page Range: Unknown

Description:

There are an increasing number of initiatives that recognize arable weed species as an important component of agricultural biodiversity. Such initiatives often focus on declining species that were once abundant and are still well known, but the ethnographic relevance of such species receives little recognition. We carried out an extensive literature review on the medicinal, ornamental, and cultural applications of three selected species, Papaver rhoeas, Centaurea cyanus, and Delphinium consolida, in the relevant Hungarian literature published between 1578 and 2021. We found a great diversity of medicinal usages. While P. rhoeas stands out with its sedative influence, D. consolida was mainly employed to stop bleeding, and C. cyanus was most frequently used to cure eye inflammation. The buds of P. rhoeas were sporadically eaten and its petals were used as a food dye. All species fulfilled ornamental purposes, either as garden plants or gathered in the wild for bouquets. They were essential elements of harvest festivals and religious festivities, particularly in Corpus Christi processions. P. rhoeas was also a part of several children’s games. These wildflowers were regularly depicted in traditional Hungarian folk art. In poetry, P. rhoeas was used as a symbol of burning love or impermanence; C. cyanus was frequently associated with tenderness and faithfulness; while D. consolida regularly emerged as a nostalgic remembrance of the disappearing rural lifestyle. These plants were also used as patriotic symbols in illustrations for faithfulness, loyalty, or homesickness. Our results highlight the deep and prevalent embeddedness of the three iconic weed species studied in the folk culture of the Carpathian Basin. The ethnobotanical and cultural embeddedness of arable weed species should also be considered when efforts and instruments for the conservation of arable weed communities are designed.

The effects of foreign direct investment on the performance of small-medium enterprises: The case of Vietnam

Laszlo Vasa Norbert Bozsik Duong Minh Ngo

Publication Name: Journal of International Studies

Publication Date: 2023-01-01

Volume: 16

Page Range: 57-70

Description:

Foreign direct investment (FDI) is one of the most important elements influencing countries' international economic integration. FDI establishes direct, consistent, and long-lasting interconnections between economies as well as encouraging innovative technology and know-how transmission across territories while allowing host economies to offer their goods more extensively on global markets. FDI is also a source of investment financing that creates the climate for appropriate policies. Aside from the obvious advantages for all economic sectors, attracting FDI in small and midsize enterprises (SMEs) has a variety of additional benefits. For example, an opportunity to participate in the global supply chain for parts and components; an opportunity not yet wholly established in most developing nations but is critical for industrialization and improving income distribution through job creation for low-skilled employees. This study compared the impact of FDI on the performance of SMEs in Vietnam to that of a group of ASEAN nations with comparable economic structures including Indonesia, Malaysia, and Thailand. The empirical evidence indicates that FDI has a negative effect on the performance of SMEs in the group of four ASEAN member countries while having a positive influence on Vietnamese SMEs.

Fuzzy Signature Based Model in Material Handling Management

Ferenc Lilik Balázs Ferenczi Ĺaszĺo T. Ḱoczy

Publication Name: Studies in Computational Intelligence

Publication Date: 2023-01-01

Volume: 1040

Issue: Unknown

Page Range: 169-179

Description:

Scheduling and management of material handling in functional production system are among the biggest challenges of logistics. Among several methods, linear programming gives exact solution to these kinds of problems, however, linear programming is rigid and requires specially trained personnel to operate. Fuzzy logic based systems—besides they work similarly to human thinking—seems to be easily implementable in such problems. In this paper we present a fuzzy signature based approach constructed on expert knowledge. Its results are compared to the results of linear programming in the same situations.

Circular Concepts and Values: Will Reuse Become Fashionable?

Cecília Szigeti Katalin Bándy Máté Farkas-Kis Sándor Remsei

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 301-306

Description:

Analysts often treat the circular economy as a technical issue. They often focus on how to organise work processes better. The authors’ concept is that circularity is much more than that, and a more precise and holistic approach can help create a better and more inclusive future for all. Young people play a key role in achieving a circular future (as a socioeconomic system). In this paper, the authors will look at how young people relate to circular processes. The research, based on a survey of 1,442 university students, took place in November and December 2022. The majority of the respondents were born around 2000 and are enrolled in undergraduate studies at Széchenyi István University. The questions of a standardised questionnaire were designed to collect information on the awareness of participation in the socioeconomic cycle process, the understanding of the context and the way of participation. The results of the research show that the students who consider themselves environmentally conscious are more likely to recycle and collect waste selectively, but it is not clear whether they participate in extending the life of the objects (swapping, second market, etc.). The research also found that students do not use and are typically unaware of online applications promoting circular lifestyles. The research sheds light on what a circular future would look like and what could be built on it.

Description:

In addition to increasing productivity, digitisation and automation are an important part of the sustainability issue. Therefore, investments aimed at environmental protection and long-term sustainability appear to be on the rise among companies with strong innovation activities in the industrial environment. This article presents the results of a study that outlines young people's assessment of the automation and digitisation opportunities on offer. In addition to traditional values, the goal is to find out how they perceive the importance of Industry 4.0 solutions in shaping the way a company operates. The survey was conducted in two countries, Hungary and Poland. It sought to answer the question of how groups, which by definition are well-defined by certain demographic characteristics, determine their preferences with regard to the above-mentioned areas and how they differentiate them. Relationships between clusters - based on preference-related differences - with respect to product manufacturing, i.e., variables that are considered important to companies, were examined. It can be concluded that the environmental issues and, due to this, sustainability is not equally important (range: 3.512 to 4.308). The traditional features of the products were important for everyone (4,407 to 4,549), and the smart features were differently evaluated (2,607 to 3,386). Overall, looking at the relationship between sustainability-related values will bring us closer to further typology and a better understanding of the clusters, making them more accessible and easier to understand and thus enabling a more effective strategy to be implemented with a focus on sustainability.
