Identifying And Analysing Occupational Hazards And Injuries Among Abattoir Workers In Oyo State, Southwestern Nigeria.
Get PDFAbattoir workers are exposed to a multitude of occupational hazards and injuries, posing significant risks to their health, safety, and well-being. These hazards include musculoskeletal disorders (MSDs), injuries from sharp tools, and ergonomic issues, such as awkward postures, repetitive motion, and excessive force, which are prevalent, contributing significantly to the high injury rates in the abattoir industry. The study aimed to examine the causes and consequences of occupational hazards and injuries among abattoir workers. Four hundred and eighty (480) workers comprising 392 males and 88 females from the five (5) geopolitical zones of Oyo State of Nigeria participated in the research survey. Risk Rating Matrix (RRM) was used to analyze the identified hazards. The common identified hazards were slippery or wet floor, sharp tools, flying bone fragments, uneven or damage table, poor workstation design, lifting heavy carcasses, and repetitive motion. The overall risk levels were 29.6 % and 14.1% at high and critical risk for sharp tools,12.5 % and 8.8% at high and critical risk for flying bone fragments, 2.5 and 0% at high and critical risk for uneven or damage table, 5 % and 4.1% at high and critical risk for poor workstation design, 9.1 % and 8.5% at high and critical risk for repetitive motion, while none were at high and critical risk for slippery or wet floor respectively.

Impact of the Projet for the Improvement of Quality and Equity in Basic Education (PAQEEB) on primary school scholastic results : a correlational analysis in the commune of Mbacke, Senegal.
Get PDFThis study aims to access the impact of the Project for the Improvement of Quality and Equity in Basic Education (PAQEEB) on primary school results in the commune of Mbacké in Senegal. The commune of Mbacke shows some of the lowest academy performance nationally, making in a key area for assessing PAQEEB’s effectiveness.A descriptive and correlational approach was employed. It relies on quantitative data collected through a survey questionnaire administered to eleven scholl principals. A composite scoring system (based on a two-point score) was applied to evaluate four dimensions of scholastic results : access to education, quality and internal efficiency of the educational system, as xelle as the perceptions and effectiveness of the PAQEEB.The data collected show a Variable Satisfaction Rate (VSR) of 100,0% for access to education, while the quality and internal efficiency of the educational system are deemed satisfactory with rates of 80,0% and 87,5% respectively. However, the pupil-teacher ratio remains high, averaging 66 pupils/teacher in 2023, compared to the reference value of less than or equal to 45 (the objective set by the PAQEEB). Regarding the statistical analysis, it reveals a nearly perfect positive linear correlation (r=0,9997) between the implementation of the PAQEEB and the scholastic results at the Certificate of Elementary School End Examination (CFEE). The Student’s t-test indicates a strongly significant correlation at the 5% threshold.The implementation of the PAQEEB has a positive and significant impact on scholastic results in the commune of Mbacké, thus confirmed the general research hypothesis. The program’s success is rooted in tis rigorous execution and in institutional and social commitment particulary to adress inequalities related to equity and performance based on gender

The paper concludes with policy recommendations to enhance ASEAN’s role as a normative and cooperative platform in safeguarding maritime peace in the Indo-Pacific
Enjeux des Guerres à l'Est de la République Démocratique du Congo
Get PDFDepuis des siècles l'Afrique a toujours été perçue comme un réservoir de richesses, importance qui lui a attiré des convoitises variées et a créé dans son giron un foyer des rivalités. Aujourd'hui, plus d'un demi-siècle après les indépendances, la République Démocratique du Congo connait des guerres suite à la convoitise de ses voisins de la sous-région (Rwanda, Ouganda et Burundi) bénéficiant du soutien de la mafia internationale, sous l'œil regardant de la communauté internationale.Ainsi, la présente étude dont l'objet consiste à donner des solutions pouvant aider le Congo-Kinshasa de tourner définitivement la page à ces guerres et de s'inscrire inlassablement dans la voie de développement, tente de s'appesantir sur les enjeux des guerres à l'Est de la République Démocratique du Congo qui s'inscrit dans un contexte de persistance avec une dose de terrorisme.En effet, il s'agit d’examiner les enjeux desdites guerres sur le territoire congolais afin d'en déduire des actions réfléchies pour mettre fin à cette tragédie qui n'a que trop duré et faute de la stopper, risque d'amener le pays à la balkanisation
Analysis Of Proptech Development Policies In The United Kingdom And The Potential For Application In The Vietnam Real Estate Market
Get PDFIn the context of technology reshaping the global real estate market, this paper focuses on analyzing PropTech development policies in the United Kingdom, one of the pioneering countries in building a real estate technology ecosystem, in order to draw relevant lessons for application in Vietnam. With over 800 PropTech companies, a total investment exceeding £1.65 billion in 2022, and a coherent policy framework, the UK has established a solid foundation based on four key pillars: (1) Open data, (2) Legal sandbox, (3) R&D funding, and (4) Triple Helix collaboration mechanisms. Through comparative analysis, the paper highlights that Vietnam possesses favorable conditions such as rapid urbanization, increasing demand for market modernization, and a strong national agenda for digital transformation. However, challenges remain in terms of the absence of a flexible legal framework and standardized real estate data. Therefore, the study proposes a localized, sector-prioritized pilot policy model as a foundational approach to develop PropTech in Vietnam in a systematic, transparent, and sustainable manner
Optimisation De L’analyse De La Valeur Par L’utilisation De La Programmation Dynamique
Get PDFDans un contexte marqué par la nécessité d’une gestion optimisée des coûts et de la valeur dans les projets de construction, l’analyse de la valeur (AV) demeure un outil stratégique. Toutefois, sa mise en œuvre se limite souvent à des approches qualitatives ou semi-quantitatives, rendant complexe l’identification des meilleures alternatives lorsqu’interviennent des contraintes budgétaires. Cette recherche propose une intégration de la programmation dynamique dans la démarche d’AV, appliquée au cas d’un bâtiment universitaire à Madagascar. L’objectif est de développer un modèle quantitatif permettant d’optimiser les choix fonctionnels en fonction des coûts et des valeurs associées. En s’appuyant sur la théorie de Bellman et le principe de décomposition en sous-problèmes, un algorithme inspiré du problème du sac à dos a été adapté. Celui-ci permet de rechercher soit une optimisation maximale, soit une optimisation minimale, selon les besoins de la décision. Les résultats obtenus mettent en évidence une structure algorithmique capable d’améliorer le processus de sélection des fonctions dans l’AV, en renforçant la rationalité et la précision des décisions. Cette approche contribue à enrichir la méthodologie traditionnelle de l’AV et ouvre des perspectives pour une gestion plus efficiente des projets de construction
Impact Des Déterminants Sociaux Dans La Propagation Des Maladies Des Mains Sales. Etudes Menées Au Marche De Libération Dans La Commune De Bumbu
Get PDFCette étude examine l’influence des conditions sociales sur la propagation des maladies des mains sales (le choléra, la fièvre typhoïde, les diarrhées aigües et tant d’autres) au marché Libération situé dans la commune de Bumbu à Kinshasa. La forte concentration humaine et l’insalubrité du site favorisent les risques sanitaires. Plusieurs éléments clés contribuent à cette situation il s’agit de : L’accès limité à l’eau potable, l’absence ou l’insuffisance d’infrastructures sanitaires, le faible niveau de sensibilisation à l’hygiène et à la prévention des maladies, ainsi que des contraintes économiques qui empêchent une bonne prise en charge de l’hygiène individuelle qui jouent un rôle majeur dans la survenue des maladies évitables. D’où, une approche multisectorielle sur le renforcement des infrastructures sanitaires locales, des programmes d’éducation sanitaire adaptés aux communautés, voire une bonne gestion de l’environnement réduirait les risques de contamination
Wind Turbine Power Forecasting Using ANN, KNN, SVM, and Linear Regression Models
Get PDFThe prediction of wind turbine active power is crucial for the efficient management of renewable energy. This study analyzes the application of several machine learning models to predict the active power of wind turbines. The ANN, KNN, SVM, and linear regression models are trained with meteorological data to assess their accuracy. The analysis of the results shows that artificial neural networks (ANN) provide the best performance (RMSE: 0.0732), while linear regression has limitations. Improving the models requires the integration of new variables and the optimization of hyper parameters to refine the prediction
Composition of Diatom Species in the Internal Organs of White Rats (Rattus norvegicus Berekenhout, 1769) as a Support for Forensic Diagnosis of Drowning Victim Cases
Get PDFForensic diagnosis of drowning victims can be done in several ways, one of which is by looking at the diatoms found on the drowning victim's body to see where the drowning victim occurred, the cause of death of the drowning victim, and determining the length of time the drowning victim took place. This study aims to determine the species and characteristics of the diatoms found in the internal organs of white rats (R. norvegicus) that were drowned in the Batang Arau River, Padang City and to determine the species of diatoms that can help forensic diagnoses at the drowning victim's crime scene. This research was carried out from October 2022 to January 2023 at the Batang Arau River, Padang City and the Animal Ecology Research Laboratory. The method used in this research is the survey method. In this study, the diatoms found in the internal organs of white rats were 19 species consisting of 147 individuals. Diatom cells are pinnate in shape, the most apex shape variations are rounded by 58% and the smallest is rostrate 10%, while the size of diatoms ranges from ±130.50 - ±1132.22 µm. Diatoms that can be used to assist in forensic diagnosis of crime scenes in the Batang Arau estuary are Eunotia bilunaris and Gomphonema pumilum.
