Authors: TUO Péga , OROU Edichi Marie Gaëlle
Published: December 2023

Abidjan, la capitale économique de la Côte d’Ivoire concentre la plupart des activités administratives, économiques et un potentiel démographique. C’est la ville qui a enregistré le 1er cas de COVID-19 à l’échelle du pays et est restée l’épicentre de la maladie. Cette étude vise à montrer l’impact des mesures de prévention sur la dynamique de propagation de la COVID-19 à Abidjan. Elle repose sur la recherche documentaire, les entretiens et une enquête par questionnaire auprès d’un échantillon de 328 chefs de ménages repartis dans les 10 communes de la ville d’Abidjan. Aussi, le test statistique de Khi-2 a été utilisé pour tester la significativité de la liaison entre la maladie et l’exposition aux facteurs de risque. Les Risques Relatif (RR) et Attribuable (RA) ont été calculés pour montrer le lien entre l’apparition des symptômes et le respect des mesures de prévention par la population. Il ressort une dynamique et une inégale répartition des cas de COVID-19 dans la ville d’Abidjan avec une forte concentration dans les communes de Cocody (37 302 cas) et de Treichville-Marcory (14 998 cas) sur la période du 11 mars 2020 au 28 février 2022. Sur l’ensemble des 328 chefs de ménages enquêtés, 70% n’avaient aucune connaissance du mode de transmission de la COVID-19. Concernant les mesures de prévention, seulement 82 soit 25% les respectaient fréquemment tandis que 234 soit 71,3% les respectaient par moment. Les chefs de ménages qui portaient fréquemment le masque avaient 4,59 plus de chance de ne pas présenter les symptômes liés à la COVID et étaient protégés à 58,34%. Tandis que 32,26 % des chefs de ménages présentant les symptômes, étaient liés au respect des mesures par moment mais également à 25,3 % de ceux qui ne les respectaient jamais. Les mauvaises attitudes et pratiques de la population face au respect des mesures de prévention de la COVID-19 demeurent inquiétantes pour une lutte efficace et durable dans la ville d’Abidjan.

Published: December 2023

The performance improvement of a three-bed (equal bed) adsorption chiller employing an advanced mass recovery process has been numerically studied in this paper. The mass recovery scheme is used to improve the cooling effect and a CFC-free-based sorption chiller driven by the low-grade waste heat or any renewable energy source can be developed for the next generation of refrigeration. Silica gel/water is taken as adsorbent/adsorbate pair for the present chiller. The three-bed adsorption chiller comprises with three adsorber/desorber heat exchanger, one evaporator and one condenser. In the present numerical solution, the heat source temperature variation is taken from 500C to 900C along with coolant inlet temperature at 300C and the chilled water inlet temperature at 140C. In the new strategy, if any one bed (3rd bed) is connect with the evaporator during pre-heating or pre-cooling time then it will give better performance than that of existing system. In this strategy, mass recovery process also occurs in all bed. A cycle simulation computer program is constructed to analyze the influence of operating conditions (hot and cooling water temperature) on COP (coefficient of performance), and CC (cooling capacity).

Granular particles have unique behaviour because it can behave like solids, liquids, and gaseous subtances. So, it is necessary to discuss the dynamics of these particles. Dynamical particles involve normal force, tangential force, and gravity force. Deposition is dropping particles at a medium, it produces a pile of particles. First step of simulation is assigned collision criteria. Next step is simulation using digital visual Fortran software and the final step is to analyze it. Based on simulation, dynamic behavior of particles is seen through on video created by assembling images of simulation result. The largest particles are fallen spread to underlying medium then followed by smaller particles. It fallen on center of pile until particles below bears a much heavier than the mass of particles. The smaller particles on center of pile pushes at the bottom and it makes cavity. As a result, the pile seems to have two peaks on static condition

Published: December 2023

Determining the best school in the education system is an essential task. One approach that can be used to determine the best school is using the generalized picture fuzzy soft set (GPFSS) concept. GPFSS is an extension of the picture fuzzy soft set (PFSS) concept in which each parameter is defined a picture fuzzy set (PFS) stating the level of importance of the parameter. This research proposes the GPFSS approach to determine the best schools. This approach is based on consideration of several factors, namely the quality of the school environment, the quality of school facilities, the quality of teachers, the quality of the learning process, and school achievement. The research results show that the GPFSS approach can accurately determine the best schools. The best schools based on the GPFSS approach have a good school environment, facilities, quality teachers, learning processes, and good school performance

The current development stage of the world economy is characterized by a series of transformations with a major impact on life on Earth. Today, we are benefiting from the advantages of the progress achieved so far, but we are also facing a number of problems caused by the limitation of natural resources, pollution, global warming etc., as well as many unknowns arising from the development of technology and research. For this reason, this whole development process will have to be carried out with more caution, less waste and with respect for all the measures adopted to protect the environment. The whole approach involves a descriptive and comparative analysis of the current process of socioeconomic development with the aim of identifying, raising awareness and managing potential threats to the coexistence of the biosphere and human civilisation. The originality of the study lies in the use of current information on the subject, obtained from various sources, such as competent bodies, the media and specialist literature. By drawing attention to the devastating effects that intensive and irresponsible development with a multitude of unknowns can have, the aim is to sound a serious alarm before it is too late. Terms such as responsibility, prudence, vigilance, sustainable development should not be missing from any management plan, both at company and macroeconomic level.

Published: December 2023

The paper aims to analyze the major necessity to find ways to achieve that development that ensures a stable balance between economic, social and environmental considerations, so that European Union must have an important place in the transition to a healthy environment in a sustainable Europe, in a sustainable world. As a starting point, we have the reality that the European Union is facing persistent environmental challenges and an unprecedented urgency in terms of biodiversity, resource use, climate change and environmental risks to health and well-being, requiring a robust understanding and effective interventions. Measures must be established to reverse current trends, urgent systemic solutions must be found. The analysis carried out demonstrates that the achievement of the objectives of sustainable development cannot be achieved without effective environmental protection policies, which also depend on the existence of a correct taxation in the environmental field. The recent global economic crisis, recording continuous and irreversible damage to the environment, with negative effects, including on human subjects, have demonstrated the capacity and the reduced limits of reaction of the economic system to the instability of the environment. Analyse performed proves, that the solutions we offer to the current must be different from those supported until now, requiring a rethinking of the attention given to them.

Authors: Ciloci Rafael , Țurcan Iuliu
Published: December 2023

The Republic of Moldova is a very vulnerable state to external factors, due to its geographical position, global or regional crises, and pandemic are challenges that are difficult to manage. Thus, the need to integrate the Republic of Moldova into the EU is obvious, a fact that would stabilize the political-economic situation, would create prospects for sustainable development. However, integration implies, in addition to rights and benefits, the assumption of certain responsibilities, such as the adoption of the acquis community, the harmonization of legislation, including the implementation of circular economy policies. At the same time, we must note that the Republic of Moldova annually generates an enormous amount of waste, which has a negative impact on the nature and quality of life. Therefore, the remodeling of the economy of the Republic of Moldova according to the principles of the circular economy would also bring direct benefits. Waste in the economy of the Republic of Moldova is largely generated by the agricultural and some industrial sectors. Thus, a set of institutional regulatory measures are needed, a fact that would allow the circular transformation to be achieved. The Republic of Moldova is only at the beginning of this transition and it is necessary to develop a strategy that would include a holistic approach and efficient use of resources.

Development of the distribution chain for moldovan fruits
Authors: Munteanu Tatiana , Stratila Alina
Published: December 2023

The distribution chain is the path through which the product or service passes from the producer to the final consumer. This chain includes a number of stages and intermediaries that facilitate the movement, storage and sale of products or services. An effective distribution chain involves planning, accurate logistics and coordination between all participating intermediaries, to guarantee that the product or service reaches the consumer in good condition, at the right time and in the desired location. A well-organized distribution chain can help reduce costs, improve efficiency and increase consumer satisfaction. The Republic of Moldova is a country with fertile soils and a favorable climate for the development of agriculture, and fruits occupy a significant part of horticultural production. Although approx. half of the territory of the Republic of Moldova is dedicated to agriculture, which accounts for only 13% of the country's gross domestic product. Recently, efforts have been made to modernize and improve agricultural production technologies in order to improve the quality and yield of horticultural production in the Republic of Moldova, but farmers still encounter difficulties, especially at the stage of organizing the marketing chain of agricultural products. Due to blockages that occur in the distribution chain, products are delayed in reaching consumers, additional costs arise and damage to production occurs, which leads to losses, low yields, reduced profits and the efficiency of agricultural activities. In this article, we have proposed to analyze the distribution channels for the fruits produced in the Republic of Moldova, to identify the main blockages encountered during the distribution chain and to identify solutions for the efficiency and effectiveness of the distribution of Moldovan fruits both on the territory of the country and abroad.
The place of glosa C1 in sustainable agricultural development
Authors: Stoian Eugeniu
Published: December 2023

Sustainable agriculture is a system of farming that is based on providing the necessary resources for current human populations while preserving the planet's capacity to sustain future generations. Over the last five decades, technologies, irrigation and mechanisation used efficiently have led to increased productivity and quality of agricultural products. But we can't just talk about the positive effects of intensive agriculture, it also has negative effects, it has led to water pollution with chemicals, soil degradation, impoverishment of flora and fauna. Following the sustainable agriculture movement that addresses the social, economic and environmental role of agriculture. To implement sustainable agricultural practice, it is crucial to take a holistic approach and recognize the interconnectedness between individual farms, local ecosystems, communities and even the entire planet. Such a perspective requires coordinated and collaborative efforts in research and education, with a focus on integrating diverse disciplines. In the transition to sustainable agriculture, responsibility does not fall on the shoulders of a single entity, but is shared between farmers, processors, government policy-makers, traders and consumers, each with a key role to play in the process.

Molecular mechanism underlying ABC exporter gating: a computational study
Authors: Wang Zi , Liao Jielou ,   Department of Chemical Physics, University of Science and Technology of China, Hefei 230026, China
Published: December 2023

ATP-binding cassette (ABC) exporters are a class of molecular machines that transport substrates out of biological membranes by gating movements leading to transitions between outward-facing (OF) and inward-facing (IF) conformational states. Despite significant advances in structural and functional studies, the molecular mechanism underlying conformational gating in ABC exporters is not completely understood. A complete elucidation of the state transitions during the transport cycle is beyond the capability of the all-atom molecular dynamics (MD) method because of the limited time scale of MD. In the present work, a coarse-grained molecular dynamics (CG-MD) method with an improved sampling strategy is performed for the bacterial ABC exporter MsbA. The resultant potential of the mean force (PMF) along the center-of-mass (COM) distances, d1 and d2, between the two opposing subunits of the internal and external gates, respectively, are obtained, delicately showing the details of the \begin{document}$ {\rm{OF}}\to {\rm{IF}} $\end{document} transition occurring via an occluded (OC) state, in which the internal and external gates are both closed. The OC state has an important role in the unidirectionality of the transport function of ABC exporters. Our CG-MD simulations dynamically show that upon NBD dissociation, the opening of the internal gate occurs in a highly cooperative manner with the closure of the external gate. Based on our PMF calculations and CG-MD simulations in this paper, we proposed a mechanistic model that is significantly different from those recently published in the literature, shedding light on the molecular mechanism by which the ABC exporter executes conformational gating for substrate translocation.

The article presents data from serological studies of blood sera of farm animals for the presence of antibodies to the Crimean-Congo haemorrhagic fever virus (CCHF). In 2022, 590 small cattle blood sera collected in 4 regions were examined, and in 2023, 1004 small cattle sera and 1090 cattle sera from 15 regions of Kazakhstan. As a result of the studies, it was established that the seroprevalence of CCHF virus among cattle in 2023 was 5.32%. Seropositive cattle were detected in 6 (Atyrau (9.38%), Kyzylorda (57.5%), Zhambyl (40%), Turkestan (78.58%), Almaty (4.77%), West Kazakhstan (1, 93%) from 15 studied regions. Seropositive sheep were detected in 4 regions in 2022 and in 5 out of 15 studied regions in 2023. The presence of antibodies to the CCHF virus was detected in 2022 in West Kazakhstan (4.5%), Turkestan (11 .3%), Zhambyl (30.9%) and Kyzylorda (44.3%) regions, and 2023 in West Kazakhstan (6.9%), Turkestan (14.52%), Zhambyl (15%), Kyzylorda (70%) and North Kazakhstan (12.1%) regions. The results of our research show that the distribution area of CCHF has expanded significantly. Based on the data obtained, we can conclude that two endemic regions for CCHF have formed on the territory of Kazakhstan: the southern endemic region, including Kyzylorda, Turkestan, Zhambyl, and Almaty regions, as well as the western endemic region, including West Kazakhstan and Atyrau regions. Given the constant movement of wild and farm animals within the country, there is a high risk of CCHF spreading from endemic regions to free regions. To confirm these data, it is necessary to conduct constant monitoring of farm animals, ticks, and other blood-sucking carriers of this virus.
Rationalism in Philosophical Studies
Authors: Afifah Umi
Published: December 2023

This article discusses rationalism which is reviewed from various scopes starting from Rationalism Figures such as, Rece Descartes (1596-1650), Baruch De Spinoza (1632-1677), Leibniz (1646-1716), Icholas Malerbranche (1638-1775), Harun Nasution, and the philosophical views of racialism towards humas, science, education, and towards curriculum (implementation in the field). Rationalism is a philosophical teaching that holds that reason, or reason, is the most important tool for acquiring and testing knowledge. Rationalism, reason is the main source of knowledge. Theoretically, he contradicts empiricism by refusing to consider the five senses as a source of knowledge. Belief that reasons has the power and authority to reveal knowledge and truth. According to rationalism, humans’ ability to seek and respond to truth is based on their natural intellectual abilities.
Kajian Filsafat Progesivisme dalam Pendidikan

Progressivism is a modern educational philosophy that calls for changes in the administration of education in order to progress. This flow of progressivism prioritizes the implementation of child-centered education in schools and limits teachers' activities only as mentors, supervisors and mentors for students. Progressivism advocates changes for the better that prioritize students and develop various student skills to realize learning. The educational curriculum prioritizes what students do, not what educators do. The goal of progressivism in education is to make educational practices that have previously seemed authoritarian become democratic and more respectful of children's potential and abilities, as well as encouraging more inclusive learning for students.

Günümüzde teknoloji hızla ilerlemekte insanlar tarafından yapılan birçok iş, çok daha hızlı ve kusursuz bir şekilde bilgisayarlar tarafından yapılabilmektedir. Özellikle doğal dil işleme yeteneği olan ChatGPT gibi modeller aynı zamanda matematiksel işlemleri de yapabilmekte, tabloları okuyup yorumlayabilmektedirler. Bu araştırmada ChatGPT’nin şirketlerin finansal tablolarını kullanarak hisse senedi değerlemesi yapmakta ne derece başarılı olduğu araştırılmıştır. ChatGPT’ye geçmişe dönük finansal tablo verisi verilmiş ve adil piyasa değeri tahmini istenmiştir. Daha sonrasında ChatGPT tarafından tahmin edilen adil piyasa değeri ile cari piyasa değeri arasındaki fark tespit edilmiş ve bu farkın takip eden bir yılda hisse senedi getirilerini ne ölçüde tahmin edebildiği araştırılmıştır. Araştırma bulgularına göre ChatGPT tarafından iskontolu işlem gördüğü belirlenen hisselerin takip eden bir yıllık dönemdeki ortalama hisse senedi performansı %87, medyan hisse senedi performansı %38 olmuştur. ChatGPT tarafından primli işlem gördüğü belirlenen hisselerin ise takip eden bir yıllık dönemdeki ortalama hisse senedi performansı %79, medyan hisse senedi performansı %32 olmuştur. Araştırma bulguları ChatGPT’nin belli seviyede değerleme yeteneği olduğuna işaret etse de elde edilen sonuçların istatistiksel anlamlılık derecesi düşüktür.
Grey Assessment
Authors: Voskoglou Michael Gr.
Published: December 2023

The assessment of human activities is an important task, because it helps to correct mistakes and to improve the overall performance of a group. Frequently, however, the individual assessment of the members of a group is performed not with numerical scores, but with qualitative grades (linguistic expressions). This happens either because the existing data are not exact, or for reasons of elasticity (e.g. teacher for students). In such cases the mean performance of the group cannot be assessed by applying the traditional method of calculating the mean value of the individual scores of its members. In this short communication, a method developed recently by the author is presented for evaluating the mean performance of a group in such cases, using grey numbers as tools. The method is illustrated by an example concerning the assessment of the mean performance of a class of students.

The observations made through this paper aim to analyse local conditions and identify optimal solutions for introducing irrigation in an agricultural farm in a hill area, located in the north of Oltenia region, Romania, more precisely Ghioroiu, Valcea County. The relief of the area is characteristic of the hill area with numerous plateaus and valleys, valleys made over the years by the hydrographic network and from the runoff from the slopes. In such areas apparently several sources of water are available, but only part of them can be used for irrigation.Water sources available in the area have been identified, namely groundwater, surface springs and surface waters (Olteț River belonging to the Olt River hydrographic basin). These sources were analysed if they can be used for agriculture through irrigation, and the result was that the Olteț River can be used in crop irrigation.The areas of agricultural land that are exploited by the respective agricultural farm were also analysed to determine which areas can be irrigated and by what method of watering.
Post-Quantum Security Overview of the Public Key Infrastructure
Authors: Bene Fruzsina , Kiss Attila
Published: December 2023

Recently, there has been an increasing focus on the investigation of quantum-safe solutions for a variety of applications. One of the pressing issues that needs to be made quantum secure is the TLS (Transport Layer Security) protocol. Proposals for its implementation have been discussed in several articles. The TLS protocol is based on PKI (Public Key Infrastructure). In addition, there are many other PKI applications that are used every day in both private and enterprise environments, so securing their use is essential. The methods currently developed to ensure adequate security will become obsolete with the advent of quantum computers. According to the Cloud Security Alliance, by around 2030, the performance of quantum computers will increase to the point where the risk of vulnerability of traditionally encrypted data will be very high. It is therefore important to make the right preparations in time to ensure that we can transform our solutions into quantum secure solutions by the time quantum computing becomes a real threat. In this paper, we present an analysis to this end, presenting quantum-safe solutions already in use and, in comparison, proposing new, well-performing solutions for a quantum-resistant PKI.
