Authors: NESTORENKO Tetyana , OSTENDA Aleksander , KRAVCHYK Yurii , NESTORENKO Oleksandr
Published: April 2023

Abstract
The article examines the issues of entrepreneurship support through the development of academic (university) business incubators. The experience of foreign universities in supporting entrepreneurship of students, graduates and university staff has been studied. The mechanism of creation of an academic business incubator within the limits of realization of the program on assistance to creation of a steady network of business incubators in Zaporizhzhia region is considered. Trends in the development of academic entrepreneurship based on of Berdyansk State Pedagogical University in the conditions of quarantine restrictions are determined.
The use of incubators and accelerators as institutions to promote the development of new business enterprises has grown worldwide in recent years. There is a significant increase in the number of (academic) university business incubators, which are incubators located in universities and closely integrated with the activities of universities for the development and dissemination of knowledge.
The universities and the education system must create an enabling environment for young people to develop their thinking as an employee and an employer. It is necessary to prepare students and teachers to improve entrepreneurial skills and knowledge to create jobs.

Keadilan Menyeluruh Menurut Pancasila dalam konsep “Sangserekan” di Toraja Serta Sumbangsihnya Bagi Krisis Ekologi
Authors: Rongrean Dody Grace Febryanto
Published: April 2023

Fokus studi ini bertujuan untuk menyikapi krisis ekologi yang terjadi hari ini. Penulis melihat bahwa, kerusakan alam diakibatkan oleh ulah manusia yang bertindak semena-mena atas alam. Perlakuan tersebut tak jauh dari konsep bahwa manusia adalah pusat (antroposentrisme), dan karenanya berhak memperlakukan alam semaunya. Akibatnya ialah lingkungan yang tercemar, pemanasan global, polusi, deforestasi dan krisis lingkungan lainnya. Penulis melihat fenomena tersebut dari sudut pandang kearifan lokal masyarakat Toraja, yaitu konsep Sangserekan. Dalam konsep tersebut dijumpai “roh” Pancasila tentang bagaimana berlaku adil secara “menyeluruh”, tidak hanya bagi sesama manusia, tetapi berlaku juga bagi alam. Metodologi yang digunakan dalam penelitian ini ialah kualitatif, dan pendekatan yang digunakan ialah fenomenologis. Penulis sampai pada temuan bahwa keadilan dalam Pancasila berlaku bagi seluruh ciptaan yang ada, termasuk alam. Dan konsep tersebut ditemui dalam konsep Sangserekan masyarakat Toraja. Dengan demikian alam adalah Sangserekan/ saudara, karenanya layak diperlakukan secara adil.AbstractThe focus of this aims to address the ecological crisis that is happening today. The author sees that, the damage to nature is caused by human activities that act arbitrarily upon nature. This treatment is not far from the concept that humans are the center (anthropocentrism), and therefore have the right to treat as they please. The result is a polluted environment, global warming, pollution, deforestation, and other environmental crises. The author looks at this phenomenon from the point of view of the local wisdom of the Toraja people, namely the concept of Sangserekan. In this concept one can find the “spirit” of Pancasila about how to act fairly “overall”, not only for fellow human beings, but also for nature. The methodology used in this study is phenomenological. The author comes to the finding that justice in Pancasila applies to all existing creation, including nature. And this concept is found in the concept of Sangserekan of the Toraja people. Thus, nature is Sangserekan/ brother therefore it deserves to be treated fearly.

Authors: Sari Marlynda Happy Nurmalita , Anggraini Dina Dewi , Kusumawati Yuli
Published: April 2023

Background: Restrictions on health services such as prenatal checks and the Pregnant Women Class program during the COVID-19 pandemic in several regions will have an impact on the quality of services for pregnant women. Purpose: Pregnancy online classes can potentially increase knowledge and reduce anxiety ahead of labor during the COVID-19 pandemic.
 Methods: Quasi-experimental and nonequivalent control group, pretest and posttest design approach Each group of 30 people (purposive sampling technique). Pre-test and PROCLASS provide material every week through videos uploaded to the WhatsApp group. The instrument uses a questionnaire (Google Form). Independent t-test and Mann-Whitney test to compare the PROCLASS and control groups. Dependent t-test and Wilcoxon test to compare the pre-and post-test in the PROCLASS group.
 Results: There were differences in the pre-post test on the variables of knowledge and anxiety in the PROCLASS group, respectively (p-value 0.000). There was a difference in knowledge between the PROCLASS and control groups (p-value 0.002), with an average knowledge of 88.83 in the PROCLASS group and 85.73 in the control group. There were also differences in anxiety levels between the PROCLASS and control groups (p-value 0.000), with an average anxiety level of 28.17 in the PROCLASS group and 45.70 in the control group.
 Conclusion: PROCLASS has proven effective in increasing knowledge and reducing the anxiety level of pregnant women before giving birth during the COVID-19 pandemic so that health workers can carry out the process (Puskesmas).
Selection of Organizational Structure of the Company in the Period of Digital Transformation Using the SCARF Model
Authors: Mamedova Natalia , Belyakova Elena , Urintsov Arkadiy
Published: April 2023

The article is devoted to the problem of selecting the organizational structure of the company during its implementation of digital transformation of business processes. The hypothesis of the study was that consideration of the needs of decision-makers can and should influence the choice of organisational structure changes during the transition to digital transformation of business processes. The decision makers for managing the integration of digital technologies into key aspects of a company's business activities have been shown to be CIOs. Motivational filters that characterize the needs of CIOs according to the SCARF model were presented in a hierarchical combination along with the types of company strategies that can be implemented during the digital transformation of business processes. The SCARF model, the Saaty hierarchy analysis method and the mixed-methods strategy provided the methodological basis for the study. The results demonstrate a justified choice of optimal organizational structure based on the factors of organizational behavior of IT directors and strategic priorities of the company. The presented results can be used to justify the decision to change the organizational structure of the company and to assess the social needs of decision makers.

THE IMPACT OF DATA SECURITY ON THE INTENTION OF VIETNAMESE CONSUMERS TO USE E-WALLETS
Authors: Hoang Thi Thu Huong , Vu Hoang Nam , Nguyen Thi Khanh Chi
Published: April 2023

E-wallets are used as a form of payment that brings many benefits to users. This article studies the impact of data security on consumer intentions to use e-wallets in the rapidly growing economy of Vietnam. The data consist of 236 observations from a survey of consumers in Vietnam. Covariance-based structural equation modeling (CB-SEM) was employed to test the proposed hypotheses. Research results show that security trust has the greatest impact on the intention to use e-wallets, followed by perceived privacy risk, social influence, and information sensitivity. The study also reveals the role of privacy policies and security concerns in consumer intentions to use e-wallets. Based on the research results, the study provides recommendations for consumers, e-wallet providers, and governmental agencies to increase awareness of and responsibility for information security among the consumers who use e-wallets.
HUMAN CAPITAL AS THE SOURCE OF ECONOMIC GROWTH
Authors: Tran Nhat Thien
Published: April 2023

This paper revisits the theoretical framework of endogenous economic growth by considering models where human capital accumulation is at the center of the growth process. Our work is in line with Lucas (2015), who calls for not giving “too large a role to exogenous technological change” (p. 86) while advocating that “the contribution of human capital accumulation to economic growth deserves a production function of its own” (p. 87). The main finding of our research provides the long-term behavior of economies, where our main results locate and extend these discussions to infinite-horizon models in several ways.
Correction Notice
Correction to Tran, N. T. and Thai, H. H. (2023). Human capital as the source of economic growth. Dalat University Journal of Science, 13(4S), 30–41.

Published: April 2023

The COVID-19 preventive measurements restrict farm-workers from travel to their farms, social distancing and lockdown to prevent them from getting infected. Consequently, farming and irrigation activities are dramatically reduced due to shortage of farm-workers and reduction of crops production. To find solutions, various technologies have been adopted to remotely connect farmers with their farm-fields from their homes and perform the same work as they are in the farm. An Internet of Things (IoT) approach, modern sensor technologies, and smart irrigation equipment are coupled to allow the collection of the field data for automatic irrigation of the field. This paper presents the IoT system based on Fuzzy logic controller that assists farmers to receive and monitor necessary irrigation data from the farm field through their smart phones and PCs. The Wireless Sensor Networks (WSNs) are deployed in the field to measure the water content in the soil and water used for plants by measuring the soil moisture dynamics throughout the entire duration of the crop growing season in the Maize crop farm. The Fuzzy logic controller was used for data analytics and intelligent decision making as well as Fuzzy logic toolbox in MATLAB to simulate irrigation scheduling process. The system saves 50% of water and energy consumption for irrigation, 80% reduction of farm-workers and increase in 20% of crop production.
PROCESSO ESTILOIDE ALONGADO E A SÍNDROME DE EAGLE: RELATO DE CASOS EM CRÂNIOS SECOS
Authors: Tavares Antonio C. , Koch Eduarda C. , Marafon Luana P. , Benan Vitor H. , Isaac Andréia , Segat Laura B. , Pereira Kleber F.
Published: April 2023

A Síndrome de Eagle é caracterizada pelo alongamento excessivo do processo estiloide do crânio (acima de 25 mm). Esse processo é uma projeção óssea da base do crânio, inferiormente ao osso temporal, medial e anterior ao meato acústico externo. O objetivo do relato foi descrever a variação anatômica encontrada nos crânios de esqueletos humanos do Laboratório de Anatomia Humana da Universidade Federal do Paraná - Campus Toledo. Ao todo, foram analisados os crânios de 18 ossadas doadas pelo cemitério de Cascavel-PR. Os exemplares foram preparados por meio de osteotécnica. Dentre as peças observadas, percebeu-se alterações no tamanho do processo estiloide de seis crânios, dentre eles, o mais alongado dos exemplares mediu 40 mm, seguido pelas medidas de 33 mm, 31 mm, 31 mm, 27,5 mm (unilaterais) e um caso de processo estiloide bilateral, o esquerdo medindo 33 mm e o direito, 31 mm, sendo assim, todos indicativos de uma possível Síndrome de Eagle. Além disso, conforme dados gerais da Síndrome, sua incidência é maior na população do sexo feminino, entretanto, os exemplares analisados apresentaram quatro dos seis crânios com o processo estiloide alongado do sexo masculino. Desse modo, tendo em vista que o processo estiloide é importante para a inserção dos músculos estilo-hioideo, estiloglosso e estilo-faríngeo, o alongamento de tal projeção pode apresentar uma correlação entre os sintomas da Síndrome de Eagle e essas estruturas, que são comprimidas ou calcificadas devido ao tamanho anormal do acidente ósseo. Comumente, quando manifestada, a sintomatologia inclui dores craniofaciais e cervicais, além de otalgia, disfagia, disgeusia e dores na região auricular e mastoidea. O diagnóstico é realizado por meio da anamnese em conjunto com os exames físicos e radiológicos para a confirmação da hipótese. O tratamento pode ser cirúrgico, através da excisão do processo, ou medicamentoso, dependendo da severidade dos sintomas apresentados pelo paciente portador da síndrome.
Special Challenges of Wildlife Forensics in Hungary

Published: April 2023

The causal relationship between human interference in both climate change and decrease in biodiversity is unquestionable. This fact supports the need to act effectively against those illegal activities affecting wildlife. Hungary is also involved in wildlife crimes, but there is a noticeable deficit in the processes of uncovering these actions, gathering proof and punishing those responsible. In this study the Authors examine what role forensics may play in the fight against wildlife crime.Aim: Present the characteristics of wildlife crimes and outline the main features of wildlife forensics.Methodology: The current national and international legal background and norms and guidelines for professional conduct are surveyed. The Authors also reviewed the most important relevant Hungarian and international scientific literature.Findings: One of the most important and vital tasks of modern civilization is the preservation and protection of the environment – with an emphasis on life on Earth. As part of this process there is a place for law enforcement to detect, punish and prevent further criminal activity connected with illegal activities involving wildlife. In Hungary the major barriers to effective punishment of those responsible for wildlife crimes are primarily: the lack of forensic technicians with sufficient specialized knowledge and practice; missing specialized standard operational protocols; insufficient knowledge of biology within law enforcement; insufficient funding of non-human genetic laboratories and the lack of adequate non-human (genetic) databases.Value: For the first time in Hungary, the Authors outline the basic characteristics of wildlife forensics.

An Exploration into the Public Theology of the Basel Missionary Society in Ghana
Authors: Opuni-Frimpong Kwabena
Published: April 2023

The article seeks to explore the Public Theology of the Basel Mission that gave birth to the Presbyterian Church of Ghana (PCG). The article argues that the theology of the Basel Mission emphasised the integration of the Christian faith and social action for social transformation. It held a position that the gospel message of Jesus Christ should not only address the spiritual needs of individuals but also their social, health, educational, environmental and economic needs. The church should therefore be actively involved in promoting justice, equality and human rights, particularly for the marginalised and vulnerable members of society. The study paid attention to the works of Hans Debrunner, Noel Smith and Kwamena-Poh who pursued various studies on the Basel Mission and the Presbyterian Church of Ghana for the actualization of the Public Theology of the Basel Mission on the operations of the Basel Mission. The study concludes that the Basel Mission has made a significant contribution to the development of Public Theology in Ghana as it has equally done so in the social transformation of Ghana. The study further makes recommendations for the churches in Ghana to consider the Public Theology of the Basel Mission, including Theology of Vocation, Prayer and Work (ora et labora) and the Bible and the Plough to serve as a drive in their pursuit of Public Theology and public witness.

Formation of the Transition Region for the Quiet Sun
Authors: Song Paul , Tu Jiannan , Wexler David B.
Published: April 2023

We propose a partially ionized collisional two-fluid model of the formation of the transition region between the cool dense chromosphere and hot tenuous corona for the quiet Sun. The chromosphere is treated as an isothermal gravity-bound two-fluid stratified atmosphere without appreciable vertical flow, on average. The different scale heights of the two fluids result in vertical evolution of the ionization state, and the transition region can be defined according to the ionization fraction. The transition region starts at the altitude where the ionization fraction reaches 0.5, the demarcation between the weakly and strongly ionized gas. The upper border of the region is defined as the temperature at which the particles possess enough energy for ionization, i.e., the first ionization potential. Within the transition region is a diffusion process in which the cold chromospheric particles gain energy and ionize through random collisions with hot coronal particles diffusing upward into the corona, whereas, when colliding with cold chromospheric particles, hot coronal particles lose energy, recombine, and fall into the chromosphere. The type II spicules can be generated when and where the local heating rate is so high that the conditions for a stratified chromosphere are not satisfied; upward flow is formed, penetrating the corona where the chromospheric gas in the spicule is ionized and dispersed. The enhanced radiation via those chromospheric neutral particles cools the coronal gas, and more recombination occurs, producing enhanced downward diffusion. The model reproduces key structural features of the transition region from first principles and a minimum of arbitrary parameters.
Assessing the effects of climate change on arthropod abundance in Azorean pastures: PASTURCLIM project's baseline monitoring data
Authors: Wallon Sophie , Melo Catarina , Tsafack Noelline , Elias Rui , Borges Paulo
Published: April 2023

The data we present are part of the project PASTURCLIM (Impact of climate change on pasture’s productivity and nutritional composition in the Azores). The project aims to assess the consequences of climate change (e.g. temperature increase) on the grass production and its quality for forage, as well as to assess changes in the arthropod communities associated with the Azorean intensive pastures. An in situ experiment was set up using Open Top Chambers (OTCs), in order to simulate an increasing of temperature (average of +1.2ºC) on pastures. In this contribution, we present the data relative to the arthropod sampling.

We provide an inventory of all arthropods recorded inside OTCs and in control plots in three intensively managed pastures dominated by grasses in Terceira Island (Azores): two of them dominated by ryegrass, Lolium multiflorum Lam. (Poaceae), located respectively at 186 m and 301 m above sea level; and one field dominated by common velvetgrass, Holcus lanatus L. (Poaceae), located at an altitude of 385 m.

A total of 41351 specimens were collected. Organisms collected belong to four classes, 15 orders, 60 families and 171 species/morphospecies (including 34 taxa identified only at order, family or genus level). Therefore, for only 137 taxa, we have a scientific name associated (n = 38918). A total of 75% of the species (n = 129 species) are considered introduced (including all the species with indeterminate colonisation status that are possibly also exotic species (n = 7622)), representing 71% of the total abundance (n = 29664 specimens). A total of 19% of the species (n = 33 species) are considered native non-endemic representing 28% of the total abundance (n = 11608 specimens). Only one endemic species was sampled, the wolf spider Pardosa acorensis Simon, 1883 (1% of the species), representing 0.2% of the total abundance (n = 79 specimens). Spiders (5056 specimens) and beetles (18310 specimens) were the dominant taxa representing, respectively, 20 and 78 morphospecies.

Since the main aim of this study was to have a better knowledge on arthropod communities present in Azorean pastures under a simulated temperature increase, the principal novelty of this paper is the contribution with distribution and abundance data to a baseline knowledge on the future consequences of climate changes on arthropod communities in Azorean pastures.
Cultures et normes adolescentes : quelles fonctions éducative et adaptative pour le harcèlement entre pairs à l’école ?
Authors: Stahel Tina , Moody Zoe
Published: April 2023

Le harcèlement à l’école émerge d’un système des pairs, composé de plusieurs élèves en interaction qui se lient pour agresser de manière répétitive des camarades. Cette contribution approfondit l’étude de la fonction du harcèlement au regard des cultures et des normes adolescentes ; elle vise à comprendre les besoins exprimés au travers de comportements inappropriés et antisociaux. Quarante-cinq adolescents (féminin= 22 ; masculin= 23 ; autre= 0) âgés entre 10 et 17 ans (M= 14) et vivant en Suisse ont participé à des focus groups et à des entretiens individuels sur leurs expériences du harcèlement. Les résultats montrent que les violences traduisent les normes prévalant dans les groupes de jeunes, indiquant les comportements plus ou moins attendus de la part des pairs et répondant à des enjeux identitaires.
Les ambivalences du militantisme ouest-allemand pour la santé des femmes : entre appropriations et remises en cause des savoirs médicaux (1971-1975)
Authors: Fourment Émeline
Published: April 2023

Résumé Cet article étudie l'émergence du mouvement ouest-allemand pour la santé des femmes en s'intéressant tout particulièrement à la manière dont la lutte pour le droit à l'avortement a favorisé le développement d'une critique féministe des savoirs des médecins entre 1971 et 1975. Il met ainsi au jour un rapport ambivalent des féministes aux médecins et à la médecine, reflet de la diversité des savoirs et des acteurs médicaux. Les militantes étudiées ici s'approprient des savoirs médicaux des États-Unis, de France mais aussi du bloc de l'Est, pour les opposer aux savoirs des praticiens ouest-allemands. Parallèlement, elles nouent des alliances avec des médecins ouest-allemands favorables à leur cause, avec lesquels elles promeuvent conjointement la méthode abortive par aspiration. Enfin, ces féministes produisent leurs propres savoirs, situés à l'intersection entre normes militantes et médicales.
Wolqayt, la terre promise et ses limites. Mobilisations nationalistes amhara, foncier et bureaucratie dans la guerre civile éthiopienne (2016-2022)
Authors: Labzaé Mehdi
Published: April 2023

Résumé L'émergence et le renforcement du nationalisme amhara en Éthiopie sont étudiés ici à l'aune des revendications foncières depuis 2016 et de leurs effets concrets dans la guerre au Tigray, entre 2020 et 2022. À partir d'une enquête ethnographique menée dans et autour de la zone de Wolqayt, dans l'extrême nord-ouest du pays, je propose une sociologie de ce mouvement devenu central dans le jeu politique éthiopien depuis 2016, et explique sur quels groupes sociaux et dynamiques politiques il s'appuie. En documentant les pratiques administratives à Wolqayt après sa conquête par les forces amhara au détriment de la région du Tigray au cours des premiers mois de la guerre civile, je montre que la mobilisation nationaliste reproduit, avec toutefois un niveau de violence et de dépossession accru, les pratiques de l'État-parti forgées par l'ancien parti au pouvoir jusqu'en 2018, le Tigray People's Liberation Front (TPLF). Cette situation donne lieu à la mobilisation de nouvelles catégories identitaires par les habitants qui critiquent l'administration nationaliste.
La politique ouvrière après la révolution des Jeunes-Turcs : un rapport de police sur la grève à Paşabahçe (1909)
Authors: Gritti Andrea Umberto
Published: April 2023

Cet article vise à éclairer les caractères de l’action politique des premiers travailleurs qui se mirent en grève dans l’Empire ottoman après la Révolution des Jeunes-Turcs de 1908, les ouvriers de la verrerie de Paṣabahçe. Il y a là une usine isolée, où la direction pouvait contrôler à sa guise la main-d’œuvre, embauchée et licenciée avec facilité. Comment expliquer la précocité des revendications exprimées sur un lieu de travail qui semblerait si peu adapté à l’émergence d’un mouvement ouvrier ? Un rapport de police concernant cette grève, conservé dans les Archives ottomanes d’Istanbul, fournit des éléments de réponse en attirant l’attention sur les modes d’action des divers ouvriers de l’usine.
Les maladies induites par le stress
Authors: Ramdani Céline
Published: April 2023

Quand nous sommes malades, notre organisme met en place des mesures pour nous guérir. Celles-ci mettent en jeu le système immunitaire, système de défense de l’organisme contre les micro-organismes. Le stress aigu améliore l’action du système immunitaire et favorise la guérison et la cicatrisation. À l’inverse, le stress chronique affecte le système immunitaire et rend l’organisme plus vulnérable aux agressions, favorise la survenue de maladies et retarde la cicatrisation. D’après des estimations de l’Organisation mondiale de la santé (OMS), d’ici 2030, les pathologies liées au stress deviendront les troubles de santé les plus débilitants et les plus répandus. Le stress chronique augmente le risque de pathologies cardiovasculaires, neurodégénératives, mentales, auto-immunes et cancéreuses.
Psychologie positive et protection/développement des ressources au service des forces armées
Authors: Martin-Krumm Charles , Jimenez Adrien , Trousselard Marion
Published: April 2023

La psychologie positive est une approche scientifique qui vise le fonctionnement optimal des personnes et des groupes. Une application au profit des forces armées s’inscrit dans le modèle Job Demands-Resources qui pose le rôle majeur des ressources, personnelles et collectives dans la gestion du stress et la prévention de l’épuisement professionnel. Différentes ressources, telles que les forces de caractère ou le sentiment d’efficacité personnelle sont définies pour envisager comment les optimiser au profit du militaire dans la triple temporalité de l’avant, du pendant et de l’après. In fine , la psychologie positive offre un cadre prometteur pour le développement des forces morales.
Les dilemmes éthiques
Authors: Canini Frédéric , Claverie Damien
Published: April 2023

Les défis éthiques sont des situations dans lesquelles un individu doit choisir obligatoirement entre plusieurs options, aucune n’étant satisfaisante pour lui. Il en résulte un dilemme éthique. Ces situations, quoique courantes dans les vies quotidienne et professionnelle, ont été modélisées en laboratoire afin de comprendre les dynamiques comportementales et neurobiologiques. Après la réaction rapide intuitive s’installe une réaction plus lente, mêlant émotion et cognition rationnelle, le tout dans une interaction corporelle et sous la pression du stress. Une réponse non éthique à un défi peut résulter en séquelles psychiques allant de la désadaptation, au burn-out , aux sentiments de honte et de culpabilité, voire au trouble de stress post -traumatique.
Pratiquer une activité de plateforme en période de chômage : une stratégie à court terme
Authors: Snape Marine
Published: April 2023

Le travail de plateforme est fréquemment associé au statut de microentrepreneur, ce qui conduit à souligner des lacunes importantes en matière de revenus de remplacement. Dans le même temps, les enquêtes sur les plateformes d’emploi donnent à voir une diversité de profils et de formes de cumul. Si le travail de plateforme est régulièrement adossé à un emploi salarié, notre enquête sur les plateformes de jobbing donne également à voir un adossement aux revenus de remplacement ou d’assistance. Cet article se propose de revenir spécifiquement sur cette population de chômeurs exerçant une activité de plateforme sous le statut de microentrepreneur. La pratique d’une activité réduite pour des individus au chômage permet d’éclairer les « formes particulières de chômage » à l’heure du capitalisme de plateforme. Après être revenu sur l’engagement dans une activité de jobbing , pour un chômeur indemnisé ou bénéficiant du RSA, l’article envisage la difficulté d’une projection à moyen terme, due à la fin des dispositifs les plus généreux, et pose alors la question de la sécurisation de leur parcours à long terme.

Authors: Núñez-Pacheco Rosa , Barreda-Parra Aymé , Castro-Gutierrez Eveling , Turpo-Gebera Osbaldo , Aguaded Ignacio
Published: April 2023

The COVID-19 pandemic has produced profound changes in higher education, with the replacement of face-to-face instruction with distance or remote education, which involves the management of digital skills by teachers and students. The purpose of this research is to analyze the perception of professors with regard to digital skills and the use of gamified strategies in the teaching-learning process in a virtual context. A questionnaire was sent to 81 professors in different areas of knowledge at a Peruvian public university during the first academic semester of 2020. A strong correlation (r≥.700, p=.01) was found between the use of ICT and gamification as a resource for teaching-learning, and a moderate correlation between the knowledge of digital competences and the possibilities of application as part of the instructional strategies. From the results obtained, it is clear that the participants have a positive perception of digital skills and gamified strategies, regardless of academic degree or area of knowledge. This could provide support for the update of those proposals targeting professors in order to improve their digital skills.

Robust optimal reinsurance strategy with correlated claims and competition
Authors: Yang Peng
Published: April 2023

This paper investigates the robust optimal reinsurance strategy, which simultaneously takes into account the ambiguity aversion, the correlated claims and the joint interests of an insurer and a reinsurer. The correlated claims mean that future claims are correlated with historical claims, which are measured by an extrapolative bias. The joint interests of the insurer and the reinsurer are reflected by the competition between them. To better reflect competition, we assume that the insurer and the reinsurer are engaged in related insurance business. The insurer is allowed to purchase proportional reinsurance or acquire a new business. Under ambiguity aversion and the criterion of maximizing the expected utility of terminal wealth, we obtain explicit solutions for the robust optimal reinsurance strategy and the corresponding value function by using the stochastic dynamic programming approach. Furthermore, we obtain the optimal reinsurance strategy under four typical cases. A series of numerical experiments were carried out to illustrate how the robust optimal reinsurance strategy varies with model parameters, and the result analyses reveal some interesting phenomena and provide useful guidance for reinsurance in reality.

Trash mulches are remarkably effective in preventing soil erosion, reducing runoff-sediment transport-erosion, and increasing infiltration. The study was carried out to observe the sediment outflow from sugar cane leaf (trash) mulch treatments at selected land slopes under simulated rainfall conditions using a rainfall simulator of size 10 m × 1.2 m × 0.5 m with the locally available soil material collected from Pantnagar. In the present study, trash mulches with different quantities were selected to observe the effect of mulching on soil loss reduction. The number of mulches was taken as 6, 8 and 10 t/ha, three rainfall intensities viz. 11, 13 and 14.65 cm/h at 0, 2 and 4% land slopes were selected. The rainfall duration was fixed (10 minutes) for every mulch treatment. The total runoff volume varied with mulch rates for constant rainfall input and land slope. The average sediment concentration (SC) and sediment outflow rate (SOR) increased with the increasing land slope. However, SC and outflow decreased with the increasing mulch rate for a fixed land slope and rainfall intensity. The SOR for no mulch-treated land was higher than trash mulch-treated lands. Mathematical relationships were developed for relating SOR, SC, land slope, and rainfall intensity for a particular mulch treatment. It was observed that SOR and average SC values correlated with rainfall intensity and land slope for each mulch treatment. The developed models' correlation coefficients were more than 90%.

In this study, we investigate the spatiotemporal dynamics of the neural oscillations by analyzing the electric potential that arises from neural activity. We identify two types of dynamics based on the frequency and phase of oscillations: standing waves or as out-of-phase and modulated waves, which represent a combination of standing and moving waves. To characterize these dynamics, we use optical flow patterns such as sources, sinks, spirals and saddles. We compare analytical and numerical solutions with real EEG data acquired during a picture-naming task. Analytical approximation of standing waves helps us to establish some properties of pattern location and number. Specifically, sources and sinks are mainly located in the same location, while saddles are positioned between them. The number of saddles correlates with the sum of all the other patterns. These properties are confirmed in both the simulated and real EEG data. In particular, source and sink clusters in the EEG data overlap with each other with median percentages around 60%, and hence have high spatial correlation, while source/sink clusters overlap with saddle clusters in less than 1%, and have different locations. Our statistical analysis showed that saddles account for about 45% of all patterns, while the remaining patterns are present in similar proportions.

Authors: Zhao Guodong , Li Haitao , Hou Ting
Published: April 2023

Recently, the theory of semi-tensor product (STP) method of matrices has received much attention from variety communities covering engineering, economics and industries, etc. This paper describes a detailed survey on some recent applications of the STP method in finite systems. First, some useful mathematical tools on the STP method are provided. Second, many recent developments about robustness analysis on the given finite systems are delineated, such as robust stable analysis of switched logical networks with time-delayed, robust set stabilization of Boolean control networks, event-triggered controller design for robust set stabilization of logical networks, stability analysis in distribution of probabilistic Boolean networks, and how to solve a disturbance decoupling problem by event triggered control for logical control networks. Finally, several research problems in future works are predicted.

Entre Anjou et Poitou, la Casse, à Louzy et Sainte-Verge. Un établissement pérenne de l’Antiquité au Moyen Âge
Authors: Bolle Annie , Farago Bernard
Published: April 2023

Un important domaine s’installe dans le courant du Ve siècle sur les vestiges partiellement arasés d’une villa antique. Des chemins l’entourent sur deux côtés, au carrefour desquels se situe l’entrée principale, marquée par un porche. Le bâtiment principal de l’exploitation est vaste et perdure jusqu’à la fin du XIe siècle avec quelques modifications architecturales, dont l’ajout d’une cheminée. Plusieurs bâtiments lui sont associés dont un balnéaire antique dont la fonction et le plan sont modifiés. Durant le haut Moyen Âge, la présence de forges et de bas fourneaux indiquent un travail de métallurgie du fer. À partir du VIIIe siècle, des silos sont installés auprès d’un chemin, ainsi qu’un petit cimetière. D’autres constructions apparaissent aux Xe-XIe siècles de l’autre côté du chemin, marquant l’émergence d’un hameau qui ne perdure toutefois pas. L’abandon de cet habitat se situe dès la fin du XIe siècle ou au début du XIIe siècle. Seul un chemin reste en fonction et constitue la limite communale entre Louzy et Sainte-Verge.
Rencontre des voies aux abords de la cathédrale du Mans. Un quartier aisé loti par un pouvoir élitaire
Authors: Augry Stéphane
Published: April 2023

Entre le palais comtal et la cathédrale du Mans, la rue Héraud, identifiée dans les sources anciennes entre le XIe et le XIVe siècle, était l’un des axes principaux de la ville, contournant par le sud l’éperon qui accueille le noyau urbain primitif. La rue longeait l’enceinte romaine et servait de jonction avec le réseau reliant les grands centres urbains de l’Ouest (Angers, Tours…). Une fouille a permis de restituer son tracé et de localiser le point de rencontre avec un autre axe de circulation perpendiculaire, la ruelle Saint-Julien. Le quartier organisé autour disparaît avec la mise en défense du secteur au début de la guerre de Cent Ans. La communauté urbaine s’ampute alors non pas d’un faubourg secondaire, mais bien d’une partie d’un quartier de la ville où réside une population privilégiée.
L’adoption de la chaîne de blocs dans le cinéma
Authors: Gaitán Katia Andrea Morales
Published: April 2023

La technologie chaîne de blocs et ses applications, telles que les contrats intelligents (smart contracts), l’organisation décentralisée autonome (OAD) et les jetons non fongibles (NFTs) font partie des technologies de l’avenir pour le financement du cinéma indépendant. D’un côté, ces innovations favorisent la chaîne de valeur du secteur grâce à la transparence et à la traçabilité des financements octroyés aux films. De l’autre, les cinéastes indépendants rencontrent beaucoup de difficultés à boucler leurs budgets et ces plateformes représentent de nouvelles dépenses, ainsi qu’une courbe d’apprentissage longue et coûteuse.
Effect of Quantum Dots Dispersion on the Structural, Optical, and Thermal Properties of Liquid Crystal System

Published: April 2023

Liquid crystal-quantum dot (LC-QD) composites are promising new materials for a number of applications in displays, energy harvesting, and photonics. In the present work, quantum dispersion in the mixture of LCs of cholesteric and nematic phases is reported. The combination of two LCs, namely Cholesteryl Palmitate (cholesteric 97%) and 4′-Pentyl-4-biphenylcarbonitrile (nematic, 98%), were used in equal proportion while CdS quantum dots were added in this mixture. The thermal, optical, and structural properties of this new LC-QD composite system were analyzed using differential scanning calorimetry (DSC), ultra-violet visible (UV-VIS) spectroscopy, Fabry-Perot scattering studies (FPSS), and Fourier transform infrared (FTIR) spectroscopy. Structural studies indicate that the QDs are uniformly dispersed inside the LC matrix rather than on the surface area. It was observed that quantum dot dispersion increases the strength of the LC mixture. It also changes the phase behavior of the LC mixture affecting the overall performance of LC-QD composite systems. The present findings would be very helpful for the design of the display and photonic devices with an improved optical response.
