Introduction: The COVId-19 pandemic has led to changes in health systems. The objective was to assess the effect of Covid-19 on the frequency of prenatal consultations (PNCs) for pathological pregnancies at the Abass NdAO Hospital centre. Materials and Methods: This was primarily a retrospective study conducted at the Abass NdAO Hospital maternity ward. The target was the medical records of women followed for a pathological pregnancy at maternity from July 2019 to November 2020. Second, the department’s qualified staffs were asked about their experiences with the Covid-19 pandemic. data collection was carried out between October 2021 and February 2022. Results: A total of 690 prenatal charts for pathological pregnancy were collected: 375 (54%) before the pandemic compared to 315 during Covid-19 (46%). The average age of women was 28.15 years. The age group 25 and 35 was the most represented (36.81%). Reasons for consultation were dominated by threats of premature delivery (51%), followed by severe pre-eclampsia (14%) and premature membrane rupture (11%), respectively. The frequency of prenatal consultations (PNCs) was inversely related to pandemic dynamics and significant monthly variations were observed. Qualified health personnel were midwives (71.40%) and gynecologists (28.60%). during the pandemic, more than the majority of staff (67%) worked 3 days a week, and 24% of health workers 5 days. The majority of staff (60%) reported experiencing overwork during the pandemic. Non-compliance with consultation days was noted in 38% of health providers. Protective equipment was not provided to 14% of the staff. Staff difficulties during prenatal consultations were fear of occupational exposure (12%) and patient reluctance (88%). Conclusion: The Covid-19 pandemic is having a major impact on prenatal consultations for pathological pregnancies at Abass NdAO Hospital. Effective measures must be taken to avoid the consequences of maternal mortality and the functioning of the s

SAGeLogE: A decision support System for Students’ Accommodation Management

引用

Journal of Computer and Communications 2024年第3期12卷 107-145页

作者： Rôlin Gabriel Rasoanaivo Pascale Zaraté Institut de Recherche en Informatique de Toulouse (IRIT) ADRIA Toulouse France Université Toulouse Capitole Toulouse France Faculté des sciences et technologies Université de Toamasina Toamasina Madagascar

SAGeLogE is the acronym of “Système d’Aide à la gestion de Logements étudiants” which means student accommodation management support system. It’s a multi-criteria decision support system designed to manage accommodation allocation for university students. Within SAGeLogE we developed the “Minimum of Ranks” (MIRA) aggregation method. MIRA method involves the application of multi-criteria decision-making methods (MCdM) to initially obtain different ranking. Thus, we chose the Weighted Sum Method (WSM), Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) and Combined Compromise Solution (CoCoSo) methods to be implemented in SAGeLogE. To prioritize the weights of criteria, the Anality Hierarchy Process (AHP) method was used. The interest of using the MIRA method was to obtain a compromised ranking coming from these three multi-criteria decision-making methods (WSM, TOPSIS, CoCoSo). So, we know that the accommodation to be allocated to students is always lower than the number of accommodation requests received by the organization. Thus, SAGeLogE proposed a technique that makes it easier to select students ranked by the multi-criteria decision-making and MIRA methods according to a method of calculation of quota of available accommodations within university residences. Finally, university accommodation managers had a wide choice of student ranking according to the methods implemented in SAGeLogE. The SAGeLogE experiment was carried out on the site of Toamasina University in Madagascar for an academic year with 2026 student accommodation applications received. The experimentation showed the ability of SAGeLogE to achieve the result.

Aerospace Clusters and Competitiveness Poles： A France-Quebec Comparison

Aerospace product development and manufacturing are key components of the air transport system. At national levels in developed countries, the aerospace industry is considered as a highly strategic sector. A solid national aerospace industry is therefore a symbol of strength. Countries are pragmatic： the positive impact of a well-developed transportation network on economic growth is indubitable and civil aircraft production is a key element of this network. Countries may also assert their sovereignty by being recognized players in the defence segment of aerospace. This paper will look at the cases of France and Quebec where local governments have invested significant public funding in poles of competitiveness （in the case of France） and clusters （in the case of Quebec）. While our examination of the France and Quebec aerospace scenes reveals a surprisingly large number of groupings, it does not indicate that all their members, large and small, equally benefit from participating in them. In this thick institutional environment, aerospace clusters and poles of competitiveness may compete against each other and become self-serving rather than representing and promoting their members.

This study aims at exploring arsenite (As (III)) removal from water using naturally available rocks (laterite, sandstone and shale) in C?te d’Ivoire. The study focused on the adsorbent dose, operating pH, contact time, initial arsenite concentration, and modelisation on the removal of arsenite by performing batch adsorption experiment with well water. The optimal dosage related to an initial As (III) concentration of 5 mg/L was about 50, 75 and 145 g/L for laterite, sandstone and shale respectively. Laterite has a better adsorption capacity in comparison to sandstone and shale. On the other hand, kinetic study reveals that the equilibrium times are 5 h for laterite, 3 h for sandstone and 8 h for shale. Results showed that laterite, sandstone and shale could remove the arsenic in groundwater at initial arsenic concentrations below 5 mg/L, satisfying the World Health Organization (WHO) standard for drinking water. Moreover, kinetics study showed that the overall adsorption rate of arsenite was described by the pseudo-second-order kinetic model.
