Improvingmaternal and child health is a health priority for many developing countries, including Mali. The objective was to study the role of community-based diagnosis in improving maternal and child protection in a vulnerable urban community in a developing country. Methodology: This was a research-action integrating a community diagnosis conducted in March 2023. The involvement of several stakeholders, including social actors including ASACO, membership card holders, district chiefs, neighborhood delegates, local authorities, and health professionals, made it possible to provide curative, preventive and promotional care. The ASACOSEKA Health Area was used as a setting for the study. The methodology was the indicator approach, contact, document review, interview of CSCOM patients, observation of the structure, prioritization of problems, development of an action plan and restitution of the report. Results: The monograph consisted of describing the characteristics of the study setting. Indeed, the ASACOSEKASI area is located on the left bank of the Niger River, with a population of 34,497 inhabitants. The CSCOM presented to describe a medical unit, a maternity unit, a laboratory unit, an ultrasound room and a medication storage room. The main pathologies found were confirmed simple malaria (45.08%), high AKI: 20.43%, confirmed severe malaria: 19.85%, suspected diarrhoea: 3.43%, trauma related to road accidents: 3.36%, pregnancy-related disorders (1%). BCG, Penta3, VAR, and yellow fever vaccination rates were above 100%. It reflects the fact that the doses administered were higher than the target population. This was related to out-of-area vaccination and lost doses. CPN1, CPN4, tetanus vaccination (VAT2) and family planning (FP) consultations all have a proportion above 100%. Maternal care is increased by out-of-area patients, particularly from Guin展开更多

We apply the local existence theory of boundary value problem for quasilinear hyperbolic system to solve this problem. The boundary value condition is set in particular to guarantee the character number condition. By this trick, the theory in quasilinear hyperbolic system can be employed to a large range of the boundary value problem.展开更多
