In this article we propose an overlapping Schwarz domain decomposition method for solving a singularly.perturbed semilinear reaction-diffusion problem. The solution to this problem exhibits boundary.lay.rs of width O（√ε ln（1/√ε）） at both ends of the domain due to the presence of singular perturbation parameter ε. The method splits the domain into three overlapping subdomains, and uses the Numerov or Hermite scheme with a uniform mesh on two boundary.lay.r subdomains and a hy.rid scheme with a uniform mesh on the interior subdomain. The numerical approximations obtained from this method are proved to be almost fourth order uniformly.convergent （in the maximum norm） with respect to the singular perturbation parameter. Furthermore, it is proved that, for small ε, one iteration is sufficient to achieve almost fourth order uniform convergence. Numerical experiments are given to illustrate the theoretical order of convergence established for the method.

At the end of the 20th century.and beginning of the 21st century. Vietnamese literature witnessed unprecedented innovations in the aesthetic thinking of writers and the narrative structure of their works. One of the most interesting manifestations of this new movement was not merely.the introduction of new aesthetic materials and factors, but the adoption and positive ＂reprocessing＂ of traditional factors---especially.historical factors and folk narrative factors. Based on intertextual theory. we would like to address the strong penetration, reproduction, and transformation of some folk story.elling models and historical materials in Vietnamese literature since 1986. Two corresponding phenomena we examine are ＂historical rewriting＂ and ＂alternative fairy.tales＂--as part of the whole process of incredulity.towards grand narratives and postmodernism in the contemporary.Vietnamese prose.

Chronic hepatitis B virus infection affects about 400 million people around the globe and causes approximately.a million deaths a y.ar. Since the discovery.of interferon-α as a therapeutic option the treatment of hepatitis B has evolved fast and management has become increasingly.complicated. The amount of viral replication reflected in the viral load （HBV-DNA） play. an important role in the development of cirrhosis and hepatocellular carcinoma. The current treatment modalities for chronic hepatitis B are immunomodulatory.（interferons） and antiviral suppressants （nucleoside and nucleotide analogues） all with their own advantages and limitations. An overview of the treatment efficacy.for both immunomodulatory.as antiviral compounds is provided in order to provide the clinician insight into the factors influencing treatment outcome. With nucleoside or nucleotide analogues suppression of viral replication by.5-7 log10 is feasible, but not all patients respond to therapy. Known factors influencing treatment outcome are viral load, ALT levels and compliance. Many.other factors which might influence treatment are scarcely.investigated. Identify.ng the factors associated with response might result in stopping rules, so treatment could be adapted in an early.stage to provide adequate treatment and avoid the development of resistance. The efficacy.of compounds for the treatment of mutant virus and the cross-resistance is largely.unknown. However, genoty.ic and phenoty.ic testing as well as small clinical trials provided some data on efficacy.in this population. Discontinuation of nucleoside or nucleotide analogues frequently.results in viral relapse; however, some patients have a sustained response. Data on the risk factors for relapse are necessary.in order to determine when treatment can be discontinued safely. In conclusion： chronic hepatitis B has become a treatable disease; however, much research is needed to tailor therapy.to an individual patient, to predict the susta

Introduction: Breech birth has alway. been a subject of great interest because of its risks of perinatal morbidity.and mortality. Aim: The aim of our study.was to compare the maternal and perinatal prognosis of breech delivery.with that of vertex delivery. Patients and Method: This was a retrospective case-control analy.ical study.carried out in the obstetrics and gy.aecology.department of Ségou hospital over a 2-y.ar period from 1 January.2020 to 31 December 2021, involving 242 breech deliveries compared with 484 top deliveries with a live single foetus without foetal malformation of gestational age ≥ 35 SA. The statistical tests used were: chi² (p Results: The frequency.of breech delivery.was 3.3%, with a predominance of caesarean section for breech presentation (64.88%) compared with 32.85% for vertex (P: 0.00;CI: (0.191 - 0.367). The perinatal prognosis of fetuses with breech presentations was marked by.a higher rate of neonatal asphy.ia (Apgar score Conclusion: Breech birth is relatively.rare in our department. It carries a higher risk of maternal morbidity.and neonatal morbidity.than breech delivery. However, the vital prognosis for the mother was identical in both groups.

Introduction: Hy.terectomy.is a surgical procedure involving partial or total removal of the uterus. It is the most common gy.aecological surgery.in the world. Objective: To describe the epidemio-clinical and prognostic aspects of gy.aecological hy.terectomies. Patients and methods: This was an 18-month retrospective prospective descriptive study.with a six-month follow-up period from 1 December 2020 to 31 May.2022 carried out in the gy.aecology.department of the Segou regional hospital. Results: Fifty.six (56) hy.terectomies were performed out of 118 gy.aecological surgical procedures (47.45%). The mean age was 47 ± 11.77 y.ars. Large multiparous women were the most common (50%), with an average parity.of 4.58. The main indications were uterine fibroids (30.4%), precancerous lesions of the cervix (17.85%) and uterine prolapse (17.85%). The abdominal route was the most commonly.used surgical route (82.14%). Hy.terectomy.was total in 100% of cases and associated with bilateral adnexectomy.in 48.2% of cases. The intra- and post-operative prognosis was satisfactory.in 94.6% of cases. No deaths were recorded. The average length of stay.was 3.28 day., irrespective of the surgical approach. Three cases of dy.pareunia were noted among those who had resumed sexual activity.
