Open Journal of Applied Sciences 2023年第12期13卷 2223-2232页

The issue related to the risk of identity impersonation, where one person can be replaced by another in online exam surveillance systems, poses challenges. This study focuses on the effectiveness of detecting attempts of identity impersonation through face substitution during online exams, with the aim of ensuring the integrity of assessments. The goal is to develop facial recognition algorithms capable of precisely detecting these impersonations, training them on a tailored database rather than biased generic data. An original database of student faces has been created. An algorithm leveraging advanced deep learning techniques such as depthwise separable convolution has been developed and evaluated on this database. We achieved very high levels of precision, reaching an accuracy rate of 98% in face detection and recognition.

Open Journal of Applied Sciences 2023年第12期13卷 2211-2222页

作者： Venance Saho Zoh Tiémoman Koné Yao konan Informatique et Sciences du Numérique Université Virtuelle de C&#244te d’Ivoire Abidjan C&#244te d’Ivoire

Mobile games are gaining in popularity among students, although the factors driving engagement remain poorly understood. This study, conducted among 378 students studying for a Bachelor’s degree in Computer and Digital Sciences at the Université Virtuelle de Côte d’Ivoire, explores the influence of game assets and colours on player engagement. Using an online questionnaire, the study identified students’ gaming preferences and their perception of colours. The results show that the key elements most favoured by students are graphics, sound design, the game system, narrative, interactivity and accessibility. What’s more, colour plays a decisive role in their preferences and commitment to educational mobile games.

In order to do a best stipulation on her consumption, it is necessary to know if a food provoke faintly, fairly or highly the glyceamia. The aim of this work was to evaluate the glycemic index of coconut water sugar from three coconuts varieties. So, with a cohort of 15 people, a capillary blood was collect after sugar ingestion and the glycaemia read directly on a glucometer. The result showed that the brown and white sugar from coconut sugar can be classified as low glycemic index food. Also, the glycemic indexes of white coconut water sugar are 2 to 3 more lower than that the brown sugar. The glycemic indexes of sugars vary according to the variety of coconut used. The sugars of the coconut palm (MYD) are more hyper-glycemic than those of the hybrid (PB121+) which is more hyperglycemic than the sugars of the coconut palm (WAT). Thus, with a controlled consumption, the coconut water sugars could be the sugars that are best for the health of the healthy and diabetic populations because it raises slightly the postprandial glucose.

Introduction: Perinatal mortality linked to fetal anemia of red cell alloimmunization in Côte d’Ivoire as in many developing countries can be explained by a lack of knowledge of Rhesus D feto-maternal alloimmunization, hence the obvious importance of carrying out a study on the problem of prevention of alloimmunization in rhesus negative births. This study takes stock of the management of this pathology in a reference hospital. Results and Discussion: Rh-negative mothers account for 6% of births, 42.7% (70/164) of women had a history of risk, about 61% of women had not had proper prophylaxis during previous pregnancies;and as many had not had follow-up of the coombs test during the current pregnancy;only 4.9% of patients had systematic prophylaxis with anti D serum at 28 weeks of pregnancy. This low rate of prevention is related to the financial difficulties of the patients, but also to a lack of knowledge of the pathology by the nursing staff. Conclusion: Good management of rhesus negative women during their pregnancy allows their incompatible child to benefit from all current treatments ensuring a healthy birth. It is therefore important for medical personnel to know how to deal with this rare disease in a small proportion of pregnant women.

This study focused on the transfer of experimental results of anaerobic digestion of liquid waste from an attiéké (steamed cassava semolina) factory to a 6 m3 pilot digester. The experimental digester and the pilot were powered as follows: Lw + U + C (liquid waste + urine + cow dung). To the results, the experimental digester mesophilic with a progressive elimination of COD. Also, the nitrogen concentrations in the experimental reactor had little removal with alkaline pH. As for the biogas product in this digester, a volume of 3.6 m3 was obtained with a positive flammability test. The transition from the laboratory scale to the semi-industrial scale retains the results of purification and fuel biogas production of the experimental digester.

The aims of the work were to study the current quality of the water in Lake DOHOU used for drinking water supply through several physical, chemical analyses and using water quality indices (WQI). In addition, the question was whether the populations are at risk after drinking water of lake following a reduction of 50% and 75% in the median and maximum values of pesticides. Thus, the results of the pesticide monitoring program were incorporated into probabilistic human health risk assessment exercises. Water samples were collected over a period of one year. Pesticides were subjected to solid phase extraction and then analyzed using gas chromatography coupled to tandem mass spectroscopy. The other parameters were measured according to conventional methods. The results showed that the most frequently detected pesticides were aldicarb (79%), simazine (79%) and monolinuron (44%). They also showed the mean values of concentrations exceeding 1.5 μg/L. Metoxuron detected at a frequency of 29% showed the maximum average concentration (13.46 μg/L). Nearly 98% of the sampling points had at least one substance with an average concentration above the quality standard (0.1 μg/L) and 80% did not meet the total concentration standards. Cumulative risk quotient estimates after 50% or 75% abatement for frequently identified pesticides were greater than unity when extreme?values for adults and children were considered. To determine the suitability of water for aquatic life, drinking water consumption and drinking water production, the water quality index (WQI), the heavy metal pollution (HPI) and the heavy metal evaluation (HEI) were calculated. The poor quality of the water was mainly related to pesticides, organic matter and microbiological parameters. Most of the nutrients and metals studied were often below the standards of drinking water and aquatic life. The Water Quality Index (WQI) has shown that water quality is degrading for these three modes of use and ranges from poor to m
