Authors:   Regional hospital no. 16, researcher, Uzbekistan, Zuxra Abdurasulova
Published: September 2024

Vaccination is essential in preventing infectious diseases, particularly in pediatric populations. However, optimizing vaccine efficacy while minimizing post-vaccination complications in children remains a significant challenge due to the developmental state of their immune systems. This article reviews current strategies for enhancing vaccine effectiveness, including the use of adjuvants, improved vaccine formulations, and personalized vaccination schedules. Additionally, it explores methods to reduce post-vaccination complications, such as pre-vaccination screening, prophylactic treatments, and minimizing antigen load. These approaches aim to provide better protection for children while ensuring safety and reducing adverse effects. The findings highlight the need for continued research into vaccine optimization tailored to pediatric needs, particularly in the era of advanced vaccine technologies.
The effect of object perception on event integration and segregation
Authors: Balta Gülşen , Akyürek Elkan G.
Published: September 2024

The perceptual system must integrate information from various points in time and space to interpret continuous sensory input into meaningful units, such as visual objects or events. To explore the relationship between the perception of spatial objects and temporal events, we modified the missing element task, a typical temporal integration task, by inserting a simple spatial object. The aim was to determine whether the perceptual processing of the object would have an impact on the frequency of temporal integration and segregation. Temporal integration was most successful when the missing element was located within the object, less successful when there was no object, and least successful when the missing element appeared outside the object. The advantage of the location of the missing element within the object was observed at display durations from 30 ms to 150 ms. Interestingly, the object provided the same benefit for integration and segregation despite their opposing perceptual demands. This study demonstrates the relationship that exists between the processing of temporal events and spatial objects, and shows how such spatial information can facilitate temporal integration.
A standardized framework to test event-based experiments

Published: September 2024

The replication crisis in experimental psychology and neuroscience has received much attention recently. This has led to wide acceptance of measures to improve scientific practices, such as preregistration and registered reports. Less effort has been devoted to performing and reporting the results of systematic tests of the functioning of the experimental setup itself. Yet, inaccuracies in the performance of the experimental setup may affect the results of a study, lead to replication failures, and importantly, impede the ability to integrate results across studies. Prompted by challenges we experienced when deploying studies across six laboratories collecting electroencephalography (EEG)/magnetoencephalography (MEG), functional magnetic resonance imaging (fMRI), and intracranial EEG (iEEG), here we describe a framework for both testing and reporting the performance of the experimental setup. In addition, 100 researchers were surveyed to provide a snapshot of current common practices and community standards concerning testing in published experiments’ setups. Most researchers reported testing their experimental setups. Almost none, however, published the tests performed or their results. Tests were diverse, targeting different aspects of the setup. Through simulations, we clearly demonstrate how even slight inaccuracies can impact the final results. We end with a standardized, open-source, step-by-step protocol for testing (visual) event-related experiments, shared via protocols.io. The protocol aims to provide researchers with a benchmark for future replications and insights into the research quality to help improve the reproducibility of results, accelerate multicenter studies, increase robustness, and enable integration across studies.

Published: September 2024

Globally, the obstetrician-led and the midwife care are the two skilled science-based maternity care models available for pregnant women. Midwife-led care is maternal and children healthcare approach in which the midwife takes the lead role in planning, organizing, and providing perinatal care to pregnant women. This study examined pregnant women’s perception and experience toward midwife-led perinated care in health facilities in Abua-Odual, Rivers State, Nigeria. This study adopted the interpretive phenomenology design. The study was conducted at Five (5) health facilities in Abua-Odual. A convenience sample of 30 percent women completed the study. In-depth interview were done using a non-structured interview guide. Collected data were analyzed using the Hsieh and Shannon s 5-step systematic content analysis technique. Ethical approval for the study was obtained from the University of Port Harcourt Institutional Review Board. The six themes that emerged under perception were: affordability of midwifery services, personalized midwife-client relationship, empowerment of women to make decision, improved continuum of care, improved women-centered care, and improved satisfaction of care. The respondents reported positive experiences and showed a willingness to receive midwifery-led perinatal care. The study revealed that women were satisfied with the financial cost of midwifery services, appreciated the midwifes expertise in providing maternity care, acknowledge the personalized relationship with the midwife, and shared that they were empowered to make decision about their health and wellbeing. This study recommends more research in this subject matter to enhance the delivery of women-friendly maternity care.

For the successful application of water-limiting technologies and methods of regulating the extraction process, which increase the effectiveness of anti-flooding measures, it is necessary to conduct a comprehensive study, including analysis of the geological and physical condition, development of rheological and filtering characteristics of the compositions used. This article presents the indicators selected as criteria for the effectiveness of isolation of aquifers with polymer solutions - with a change in one group of geological– physical, technical and technological factors characterizing the well and processing technology. Thus, the conducted studies have shown that the amount of sediment formed can be adjusted by choosing the appropriate concentration of polymer and alkali for each specific case of treatment of the bottomhole zone of the well, and thereby the effectiveness of limiting using sedimentary gel-forming compounds is achieved. In the article, we have processed the results of experimental studies using methods of mathematical statistics. At the same time, we have established the dependence of the amount of sediment on the concentration of alkali at a stable value of the polyacrylamide concentration.

Published: September 2024

Students need to be able to think critically in order to meet the challenges of the 21st century. Be that as it may, the decisive reasoning abilities of understudies are still somewhat low. The RADEC model is a learning model that can aid in the development of critical thinking abilities. The goal of this study is to find out how well the RADEC model helps students in high school think critically about colloidal materials. This study employs experimental, quantitative research techniques. The populace is all understudies in class XI MIPA at SMAN 5 Samarinda. The examples were understudies from class XI MIPA 2 and XI MIPA 4 at SMAN 5 Samarinda, adding up to 75 individuals. The exploration test was chosen utilizing a group irregular inspecting strategy. One-group pre-test post-test design was utilized in the research design. Information assortment involves tests as pre-tests and post-tests, educator and understudy movement perception sheets, and understudy reaction surveys. Statistical tests were conducted first, including the N-Gain test and the effect size test, for data analysis. According to the findings of the research, the RADEC model meets the effective criteria in terms of students' responses to learning based on the RADEC learning model and their increased critical thinking abilities. The findings of the research lead us to the conclusion that the RADEC model works to improve students' critical thinking abilities.
Numerical Study on the Impact of the Richardson Number on Convection in an Enclosure, with Moving Sidewalls for Three Aspect Ratios: A = 1, 2 and 0.5
Authors: Messai Tarek , Kholai Omar , Boudebous Saadoun , Moussaoui Mohammed
Published: September 2024

Using mathematical models, this research investigation seeks to explore how varying aspect ratios and the Richardson number impact the mixing effectiveness, fluid flow velocity, and heat transfer characteristics in a rectangle-shaped space where cooling occurs along the sides and warm with a steady temperature exists throughout the 80% of the bottom section's center. Discretizing the governing equations through the finite volume approach, we solved them iteratively using the Tri-diagonal Matrix Algorithm, where pressure-velocity coupling was successfully implemented via the SIMPLER procedure. Innovative approaches for convection and diffusion terms involved employing a power-law difference scheme alongside a central differential scheme. In various simulations with specified parameters (Re = 100, Pr = 0.71), we visualized results in forms like streamlines, isothermal lines, and temperature/velocity profiles, along with local and average Nusselt numbers. We observe five unique structure formations during flow behavior by analyzing how Richardson numbers impact heat transmission within a specific geometric configuration (enclosure size A = 1). A change in aspect ratio leads to improved control over fluid movement while minimizing structural distortion. A subtle rise in heat transmission emerged as the average Nusselt number and Richardson number intersection strengthened force convection's domination while experiencing significant escalation under conditions conductive to natural convection. Decreasing the aspect ratio increased heat transfer efficiency when the Richardson number rose.

Trade Facilitation as a Catalyst for Government Revenue Enhancement: Exploring the Synergies Between Trade Efficiency and Tax Collection
Authors: Gumbo Nombeko , Nkala Peter
Published: September 2024

Customs administrators worldwide are mandated to mobilize national revenue collections through the assessment and collection of applicable duties and taxes on all imports and exports. One of their primary concerns following the ratification of the Trade Facilitation Agreement is the need to optimise revenue collections while simultaneously upholding trade facilitation. This research assesses trade facilitation implications on government revenue mobilization in developing countries with a particular emphasis on Zimbabwe. The paper adopts a qualitative approach, capturing several subjective elements including the examination of the Critical Success Factors for enhanced revenue collection as well as the evaluation of trade facilitation as a solution to customs revenue leakages. Purposive sampling was employed to collect data from employees working in the Customs Division at the Zimbabwe Revenue Authority. Eighty questionnaires were distributed to participants working in Beitbridge, Chirundu, Forbes border posts and the Robert Mugabe International Airport targeting Customs Senior Managers, Customs Middle Managers, Revenue Supervisors and Revenue Officers as key respondents. Data was analysed using the Statistical Package for Social Sciences version 29. This analysis focused on four dimensions of trade facilitation, which includes port efficiency, customs environment, regulatory environment, and electronic-business. The findings indicate that trade facilitation reforms, when executed appropriately in conjunction with enhancements in electronic-business, port efficiency, customs environment and the regulatory framework, can effectively augment revenue collection. Regulatory environment improvements are key in influencing increasing revenue collection and should be prioritised in resource allocation for the achievement of best possible outcomes. We recommend ‘continuous refresher training’ on trade facilitation awareness targeting all stakeholders in ports of entry, accompanied by the implementation of robust risk management strategies as well as intensified implementation of integrity management tools.
Empowering Women via Handicrafts
Authors: Malhotra Ananya
Published: September 2024

I founded 'Enchanted Threads,' a small handicraft business that weaves and crafts crochet garments, utilities, and ornamental items. The journey has been incredibly fulfilling and enriching. The venture gave wings to my creative and entrepreneurial expressions and helped me witness a positive transformation in the lives of the women working alongside me. I never imagined that an initiative spurred by the monotony of the COVID-19 pandemic would not only provide all of us with financial independence and artistic freedom but would also become a precursor to social inclusion and economic empowerment for the lives of numerous young women who work at Enchanted Thread. This has prompted me to reflect on the influence of the handicraft industry in advancing women's empowerment, as well as the government's initiatives to promote such endeavors and the obstacles that may be encountered. This review paper aims to study the same.

Multistage sampling was used to select 377 respondents comprising of 328 grade 8 learners, 42 grade 8 class teachers and 7 Sub- County Quality Assurance and Standards Officers. Psychometric test instrument, questionnaires and interview schedules were used to collect data from sampled respondents. Reliability of the instruments was ascertained through Cronbach analysis of data obtained from a pilot study carried among 53 respondents sampled from the same study area but who were not involved in the actual study. Data was collected from 325 grade eight learners, 41 grade eight class teachers and 5 Sub-County Quality Assurance and Standards Officers (SQASO) in Tharaka Nithi County giving the study a return rate of 98.41%. Qualitative data obtained was analyzed thematically while quantitative data was analyzed descriptively and inferentially with the aid of the Statistical Packages for Social Sciences (SPSS) version 27.0 computer software. Frequencies and percentages were used to describe the existing relationship between the variables while hypothesis was tested using regression analysis at 95% level of significance. The study established that a positive social relationship between among peers and positive interactions between learners and teachers catalyze the social environment which promotes junior school learners psychological wellbeing. It concluded that the school’s social environment is negatively and significantly related to the psychological wellbeing of junior school learners.The study recommended that management of public junior school in collaboration with other education stakeholders launch and monitor turn-around initiatives aimed at fostering quality school social environment for learners’ improved psychological wellbeing. Areas of focus could include workshops on peer relations, stress management techniques, seminar on teacher-learner interaction, problem-solving techniques, and goal-setting for social and academic success could be part of the initiatives.
What is the Effectiveness of Salt and Pepper in Preventing Rainbow Table Attacks in Modern Password Hashing Algorithms?
Authors: Meganathan Niyaa
Published: September 2024

Password security remains a critical concern in the digital age, as attackers continuously evolve their techniques to crack password databases. Among the most effective defenses against these threats are salt and pepper, two cryptographic techniques used to enhance password hashing security. Salt introduces unique, random values to each password, ensuring that even identical passwords result in different hashes, while pepper adds a hidden system-wide secret to further complicate attacks. This paper explores how salt and pepper work together to defend against rainbow table attacks, significantly increasing the complexity for attackers attempting to reverse-engineer password hashes. While these techniques provide strong protection, they are not foolproof and must be paired with additional security measures such as key-stretching algorithms and multi-factor authentication (MFA) to offer comprehensive defense. The paper also examines the limitations of salt and pepper and suggests future advancements, such as post-quantum cryptography and passwordless authentication, as potential pathways to further improve password security.
Experimental Method for Measuring Cohesion of Regolith via Electrostatic Lofting
Authors: Pett Charles T. , Hartzell Christine M.
Published: September 2024

The hypothesized electrostatic lofting of individual regolith grains on the Moon and asteroids has been investigated extensively in laboratory studies. Cohesion may dominate how regolith behaves on these small, airless bodies, yet the magnitude of this force remains uncertain. We induce the electrostatic detachment of dust as a mechanism to break cohesive bonds between individual zirconia-silica microspheres in order to measure the interparticle cohesive force between them, likely dominated by capillary bridges. A high-speed camera imaged centroid positions of the lofted microspheres over time. Using the centroids from the initial detachment, we numerically calculated initial accelerations to solve for the cohesion that had been restraining the microspheres. Unexpectedly, the electrostatic lofting of clumps of particles was observed and experimental results showed that clumps were a nonnegligible portion of the lofted object population.

Patient characteristics, treatment regimens, down-staging rates, pathological response, and overall survival (OS) were evaluated.Results: Both T4a and T4b patients experienced down-staging following nCRT (36.6% and 6.2% respectively; p = 0.021). T4a patients exhibited a higher rate of pathological complete response (pCR) than T4b patients (13.3% in T4a vs. 0% in T4b; p = 0.122). After a median follow-up of 36 months, the OS and recurrence-free survival (RFS) of T4a patients were significantly higher compared to T4b patients (hazard ratio [HR] = 2.52, 95% confidence interval [CI] 1.05–6.05, p = 0.038 for OS; HR = 2.32, 95% CI 1.09–4.92, p = 0.025 for RFS).Conclusion: This study provides valuable insights into the effectiveness of nCRT in T4 rectal cancer patients. Although down-staging was observed in both T4a and T4b subgroups, achieving a pCR remains a challenge, particularly in T4b patients. Further research is needed to optimize treatment strategies and enhance pCR rates in T4 rectal cancer patients to improve oncologic outcomes.
Accompagner la dissémination de l’intelligence artificielle pour en tirer parti
Authors: Caseau Yves
Published: September 2024

L’intelligence artificielle (IA) est une technologie de transformation qui va s’inviter dans l’ensemble des activités humaines (dans la société civile, comme dans les entreprises) en s’intégrant massivement dans l’ensemble de nos logiciels. Elle n’est pas un but en soi, mais un moyen. L’enjeu stratégique et compétitif est la maîtrise de ces méthodes par les acteurs de l’écosystème français, et la vitesse d’acquisition des compétences et des savoir-faire nécessaires à cette diffusion. Les entreprises doivent développer leurs capacités de mise en œuvre en travaillant sur leurs infrastructures de données, sur leur environnement logiciel (qui doit être ouvert au monde du logiciel libre) et en favorisant le travail itératif de petites équipes pluridisciplinaires en cycle court. L’article, qui s’appuie sur un rapport de l’Académie des Technologies, se propose de développer des « pratiques d’ingénierie de l’intelligence artificielle » autour des tests, du développement de protocoles d’apprentissage, de la certification de bout en bout des processus d’utilisation des données et de l’auditabilité des procédés.
La mise en place du cognitif au sein du Crédit Mutuel
Authors: Rublé Frantz
Published: September 2024

Au moment où la transformation digitale fait évoluer le comportement de ses sociétaires clients, où ses conseillers ont besoin d’être assistés dans leurs activités quotidiennes pour fournir les meilleurs services à ces derniers et où les premières solutions cognitives s’appuyant sur la technologie Watson d’IBM font leur apparition, le Crédit Mutuel et IBM, son partenaire depuis 55 ans, s’associent pour développer les premières solutions cognitives en langue française. Nous nous attacherons à expliquer ici comment les travaux initiés à la mi-2015 ont abouti à trois premières solutions (un analyseur d ’e-mails et deux assistants virtuels) déployées durant le premier semestre 2017 dans 2 800 caisses du Crédit Mutuel et agences du CIC auprès de 20 000 conseillers, au cœur de la relation avec leurs clients-sociétaires. Seront notamment abordés l’entraînement initial, l’apprentissage continu, les limites (actuelles) de ces technologies, les nouveaux cas d’utilisation à venir et les sept premiers enseignements tirés de ce projet.
Les impacts de l’intelligence artificielle sur l’emploi : comment favoriser la complémentarité avec l’humain et faire émerger de nouveaux types de métiers ?
Authors: Chapuis Reynald
Published: September 2024

L’intelligence artificielle (IA) est encore fortement méconnue et incomprise, notamment lorsqu’il s’agit d’évaluer son impact réel sur l’emploi. L’IA est aujourd’hui majoritairement utilisée par les entreprises privées et publiques pour automatiser des tâches dites routinières. Elle a donc pour vocation non pas de se substituer aux hommes, mais plutôt de solliciter leur intelligence sociale et créative et de faire se développer la valeur-conseil. Dans les années à venir, l’enjeu va donc consister pour les entreprises à faire évoluer les métiers de leurs salariés pour les rendre complémentaires de l’IA en favorisant notamment davantage l’apprentissage de compétences transverses au détriment de l’acquisition de compétences techniques. Pôle Emploi a déjà recours à l’IA, par exemple pour permettre à ses conseillers de se concentrer sur des tâches à plus haute valeur humaine. Il est ainsi mis à leur disposition une interface qui leur recommande des services et formations à suggérer à un demandeur d’emploi.
Intelligence artificielle et publicité
Authors: Niccoli Romain , Le Ouay Franck
Published: September 2024

L’intelligence artificielle (IA) a joué un rôle-clé dans le développement de la publicité digitale. Les techniques de machine learning (apprentissage par la machine), nourries par des quantités colossales de données sur le comportement des internautes, ont permis de personnaliser l’expérience publicitaire de chacun et ainsi de générer de très gros gains de performances. C’est notamment le cas des publicités sur les moteurs de recherche ou des bannières graphiques que l’on voit partout sur Internet. De grandes marges d’amélioration sont encore à attendre dans le futur mais, dans le domaine de la publicité, l’IA se cantonne encore pour l’instant à un rôle d’exécution et reste loin de pouvoir produire elle-même des stratégies marketing évoluées.
Une toile de fond pour le Web : lier les données et lier leurs vocabulaires sur la toile, pour un Web plus accessible aux machines
Authors: Gandon Fabien
Published: September 2024

Le Web touche plus de 3 milliards d’utilisateurs directs. Cependant, depuis plusieurs années il n’est plus seulement utilisé par les humains mais aussi par les machines. Cet article explique comment se tissent sur la toile un Web de Données et un Web sémantique pour y décrire tout ce qui peut être identifié, et pour échanger entre machines et à l’échelle mondiale des données structurées dans tous les domaines, ainsi que les règles et vocabulaires qui donnent leur sens à ces données et en permettent l’utilisation et la réutilisation.
Blockchain : quelle confiance, pour quels usages ?
Authors: Jeanneau Clément
Published: September 2024

La blockchain permet de décentraliser la valeur, comme Internet l’a fait avec l’information. Avec la blockchain , tout internaute peut créer et échanger ses propres actifs de valeur, avec l’internaute de son choix, (quasi) instantanément, sans nécessiter la permission d’un tiers. Cette technologie ouvre différents usages, qui commencent à être mis en application dans divers domaines. Ces usages nécessitent cependant d’accorder sa confiance à une technologie qui paraît souvent complexe, et est parfois controversée. Faire confiance à la blockchain nécessite de comprendre ses principes, les nouveautés qu’elle apporte, mais aussi ses limites, au-delà des discours quelquefois sans nuance qui entourent cette innovation.
L’atout confiance Maîtriser le risque numérique pour construire la cyber-résilience
Authors: Caparros Fabien
Published: September 2024

Pour une organisation, publique ou privée, la confiance a bien des vertus. Elle permet, en particulier au dirigeant, de consacrer les ressources adéquates à la réalisation de la mission ou à la création de valeur, et de gérer sereinement les aléas. Mais face à l’évolution du risque numérique, qui au fil des ans est devenu à la fois stratégique et systémique, comment avoir confiance en son activité numérique ? Comprendre et maîtriser ses risques numériques apporte des solutions à cette problématique essentielle. Cela demande, néanmoins, un niveau de maturité élevé pour une organisation. Lorsqu’elle y parvient, celle-ci ne sera pas immunisée contre une attaque informatique, mais elle sera prête à y faire face. Devant les menaces informatiques, le management des risques numériques permet de bâtir la confiance sur trois niveaux : la confiance dans son organisation, la confiance dans ses partenaires et la confiance dans son écosystème. Il fournit ainsi un atout significatif et difficile à acquérir : l’atout confiance.
Numérique de crise dans les collectivités locales : le rôle des infrastructures de la contribution
Authors: Guillot Louise , Ollivier Yoan
Published: September 2024

Dès le premier confinement en mars 2020, les collectivités locales se sont efforcées d’innover dans leur pratique. Dans ce contexte critique, de nouveaux modes de coopération sont apparus, la relation des institutions publiques aux usagers et aux citoyens s’est recomposée. De multiples innovations ont émergé – plateformes de mise en relation entre citoyens, plateformes d’appel aux habitants isolés, etc. Construites pour faire face à la crise, ces diverses réponses éclairent la manière dont le numérique a trouvé sa place dans cette période, et esquissent la place qu’il pourrait occuper demain, dans la perspective d’une action publique plus contributive. Nous proposons ici de revenir sur trois usages et détournements d’usage du numérique observés dans la crise. Nous verrons comment ces expériences rencontrent et outillent les transformations en matière de coproduction de l’action publique.
Logistique urbaine et pandémie de Covid-19
Authors: Dablanc Laetitia
Published: September 2024

L'effet de la pandémie de Covid-19 sur la logistique urbaine est considérable. Du côté de la demande, on a vu une forte accélération des commandes en ligne (concernant tous les âges et toutes les catégories socio-professionnelles - CSP), le développement de l’offre multicanale des commerces, de nouveaux services de livraison développés par les restaurants et, d’une façon générale, un usage renforcé des technologies (applications sur smartphones ) pour gérer les logistiques sectorielles et domestiques. Du côté de l’offre, l’adaptabilité et la flexibilité se sont révélées remarquables malgré l'imprévisibilité des commandes et les nouvelles exigences des clients. Les algorithmes sont de plus en plus sophistiqués pour optimiser les activités de livraison tandis que les opérateurs accélèrent leur transition vers des logistiques urbaines plus durables (véhicules électriques de livraison et vélos-cargos). Les villes elles-mêmes ont appris des bouleversements apportés par la pandémie pour faire davantage de place aux questions du transport des marchandises et d’immobilier logistique dans leurs plans d’action.
