Qualité de l'éducation dans le secondaire public général en Côte d'Ivoire
Authors: KOFFI Marina , N'CHO Aline , NGUESSAN Hendersonn 
Published: March 2023

Depuis la conférence de Dakar en 2000, la recherche d'une éducation de qualité est au coeur de nombreux programmes de gouvernements de pays africains. Ce besoin de qualité dans l'éducation est aujourd'hui plus que hier présent et pressant pour tous les cycles d'enseignement en Côte d'Ivoire. Dans le secondaire particuliêrement, le problême de qualité est perçu à travers les taux élevés d'abandon, les faibles taux de promotion et les faibles taux de réussite aux différents examens du BAC et du BEPC. Ce constat général, contraste cependant avec les résultats individuels de quelques établissements qui réalisent de bons résultats. Ce sont: les établissements d'excellence et certains de statut commun. Pourquoi alors, dans cette crise de dépréciation de la qualité de l'enseignement secondaire, ces établissements se distinguent-ils par la production de bons résultats?
Nous avons donc dans sept établissements situés dans deux villes que sont Abidjan et Yamoussoukro analyser l'influence des facteurs de politiques d'efficacité interne des établissements d'excellence et de statut commun sur leurs performances.
Les résultats de l'enquête montrent que les différences de performances entre établissements s'expliquent par les différences dans la manipulation de mêmes facteurs tels que : l'assiduité, le mode de gestion du temps d'apprentissage, l'encadrement des élêves, le matériel pédagogique et les équipements. Il ressort que les dispositions telles que l'internat, les cars écoles, l'intégration d'heures d'études surveillées dans les emplois du temps des élêves, les ratios élêves-classe et élêves-enseignant faibles et la disponibilité en quantité suffisante du matériel pédagogique sont les éléments de ces facteurs qui concourent à l'amélioration des performances des établissements et partant de leur efficacité interne.

Published: March 2023

<p>Following the publication of a recent journal article, I have been re-imagining and re-designing library training. The training material is part of an ongoing conversation with library staff and academics in the Faculty of Theology and Religion. Academics agree that we must teach our student's information literacy and critical thinking in light of changes in higher education.</p>
<p><br></p>
<p>Through holistic research and previous personal experience, I have discovered new pedagogical approaches to communicating library training to University of the Free State students. </p>
<p><br></p>
<p>I firmly believe in grounding library practice in theory. Library training should be rooted in education theories and blended learning models. Information literacy programs should enhance students' abilities to identify, use and evaluate information sources for self-directed learning.</p>
<p><br></p>
<p>These training materials are a springboard for transforming how librarians communicate library training/instruction, particularly to first-year students. </p>
<p><br></p>
<p>There has been an ovewhelming response to the social constructivst approach employed in the embedded information literacy program by students in the module <em>Introduction to Old Testament </em>(TOTT1513). </p>
<p><br></p>
<p>The package consists of a guide, and appendices (e.g. syllabus with blended activities, and lessons plans).</p>

Authors: Okur Sıtkıcan , Okumuş Zafer 
Published: March 2023

Objectives: The aim of this study was to evaluate and monitor the effect of low-level laser therapy (LLLT) and therapeutic ultrasound (TU) alone, or combined with intra-articular prednisolone (P) in Freund’s complete adjuvant (FCA)-induced knee arthritis model in rats.
Materials and methods: A total of 56 adult male Wistar rats were divided into seven groups: control (C), disease control (RA), P, TU, LLLT (L), P + TU (P+TU), P + LLLT (P+L) groups. The skin temperature, radiography, joint volume, serum rheumatoid factor (RF), interleukin (IL)-1β, serum tumor necrosis factor-alpha (TNF-α), and histopathological evaluation of joint were performed.
Results: Thermal imaging and radiographic examination provided results consistent with the severity of the disease. The mean joint temperature (°C) was the highest in the RA (36.2±1.6) group on Day 28. The P+TU and P+L groups significantly decreased radiological scores at the end of the study. The rat serum TNF-α, IL-1β, and RF levels in all groups were significantly higher compared to the C group (p<0.05). Compared to the RA group, serum TNF-α, IL-1β, and RF levels were significantly lower in the treatment groups (p<0.05). The P+TU and P+L group was showed minimal chondrocyte degeneration and cartilage erosion and mild cartilage fibrillation and mononuclear cell infiltration of synovial membrane compared to the P, TU, and L group.
Conclusion: The LLLT and TU effectively reduced inflammation. In addition, a more effective result was obtained from the use of LLLT and TU combined with intra-articular P. This result may be due to insufficient dose of LLLT and TU, thus further studies should be focus on at higher dose ranges on FCA arthritis model in rats.

Purpose: Since the breakout of COVID-19 pandemic, various preventive measures have been put in place by WHO to prevent the spread of this disease. However, some people are unaware or less likely to follow rules regarding hygiene, physical distancing, properly wearing of face mask and body temperature measurement. One of the best solutions to this challenge is the introduction of the internet of things (IoT) technology to assist in implementation of the preventive measures. This paper presents an IoT-enabled solution that uses Fuzzy logic controller to assess the risks of being COVID-19 infected and monitor environment conditions in the public hall to limit the spread of the coronavirus.
Methodology: The proposed model employed sensors to measure in real-time the body temperature, hand sanitization, wearing of face mask, room ventilation and IP camera controlled by Fuzzy logic controller for decision making. In addition, it uses raspberry-pi for processing and data transmission to the cloud, liquid crystal display (LCD) for displaying data and web application was developed for user interface. The resulting sensor measurements were simulated using MATLAB software and the system made automatic decisions.
Findings: A prototype was implemented effectively and the results obtained from the system were fast, accurate, efficient and cost effective when compared to other commercially available systems.
Unique Contribution to Practice: The actual practice for implementing the preventive measures require the presence of the health care personnel (HCP) which is time consuming and risky for HCP. Therefore, this system works autonomously and effectively in monitoring and controlling the implementation of the COVID-19 preventive measures in the public hall.
