Despite existing policies on training health professionnels in essential newborn care (ENC), neonatal mortality still remains high in Mali. Our work aimed to assess the level of knowledge of health staff about ENC. Material and methods: From March 20th to April 20th, 2016, we interviewed newborn care providers at the six reference health centers and the Gabriel Touré University Hospital Center in Bamako. Results: In total, we interviewed 407 newborn care providers with a sex ratio of 0.52. Interviewees had over five years work experience in 62.1%. They considered a low Apgar score as an indication for neonatal resuscitation in 89%, regardless of profile (p = 0.1583). They knew the good aspiration technique in 54%, with nurses and midwives more knowledgeable (p ) of the reference health centers (p = 0.0000). The interviewees knew the indication and rate of ventilation in 30.2% and 16.0%, respectively. About one third (34%) thought oxygen administration should be systematic during ventilation. The knowledge level on ventilation was the lowest in the group of general practitioners (p = 0.0063 for oxygen indication and p for the technique). Knowledge level for other ENC components (temperature maintenance, eyes care, breastfeeding) were higher. The knowledge of the delay of the breasting did not correlated with either the profile (p = 0.0857) or the place of practice. The knowledge of the first bath was dependent on both the professional profile (p = 0.0002) and the reference level (p = 0.0238). Conclusion: The level of knowledge of health professionnels on ENC should be improved. This will involve the integration of ENC in initial training curricula along with an appropriate continuing training policy thereafter.

ASYMPTOTIC STABILITY FOR GAUSS METHODS FOR NEUTRAL DELAY DIFFERENTIAL EQUATIONS

引用

Journal of Computational Mathematics 2002年第2期20卷 217-224页

作者： sidibe, BS Liu, MZ Harbin Inst Technol Dept Math Harbin 150001 Peoples R China

In [4] we proved that all Gauss methods areNtau(0)-compatible for neutral delay differential equations (NDDEs) of the form y'(t) = ay(t) + by(t-tau) + cy'(t-tau), t >0, (0.1) y(t) = g(t), -tau less than or equal to t less than or equal to 0, where a, b, c are real, tau > 0, g(t) is a continuous real valued function. In this paper we are going to use the theory of order stars to characterize the asymptotic stability properties of Gauss methods for NDDEs. And then proved that all Gauss methods are Ntau(0)-stable.

Journal of Harbin Institute of Technology(New Series) 2007年第2期14卷 184-188页

作者： sidibe Marie Bernard 付宜利徐贺马玉林 School of Mechanical and Electrical Engineering Center of Advanced Manufacturing Technology Harbin Institute of Technology

A new castor wheel mechanism for omni-directional mobile platform is presented. A motion of translation is transformed into a rotation to steer the wheel with the help of a helical path fits into a translation joint and three rollers whose axes are connected to the driving shaft of the wheel. When the path moves in translation it acts on the rollers for steering. The path-roller friction transmission, the wheel kinematics and the maneuverability have been analyzed.

外商在非洲农田的直接投资呈现出新的加快态势。在经历近期的粮食、能源危机,以及金融、环境危机后,耕地的需求大大增加。粮食如小麦、大米的价格在某些情况下翻了一倍,甚至两倍。经济实力强大的国家租赁本国境外的大面积耕地,以保障国内粮食、能源及物资的供给。外商直接投资新趋势集中到非洲国家,特别是马里。关于对外直接投资是给东道国带来发展机会还是在剥削穷人的争论一直持续不休。在新自由主义背景下,强大的全球机构正在促进对外直接投资,并且表示这是非洲国家赢得经济发展的契机。由于在对外直接投资新趋势这一领域研究仍有大片的空白,此文旨在帮助填补这部分的缺口,分析当地农民在office du Niger,马里执政下的外商直接投资耕地的处境。研究表明在office du Niger引导下的对外直接投资是典型的剥夺式积累。在非洲尤其在马里,土地征收规模是什么?为了回答所有的问题,本文分为以下六个章节:第一第二章分别介绍和综述了马里的背景,以及西非的土地政策,马里的土地征用,也讨论土地征收的影响。第三第四章探讨了土地征收的实证研究以及问题。第五章举例说明了"Moulin Moderne du Mali”的投资例子。第六章是关于马里耕地国外直接投资的结论和建议。此文的研究方法是采访office du Niger的执政情况和收集相关信息。受访者普遍经历了镇压、无产阶级化,帝国将他们的生活和环境进一步拖进无尽深渊。但是在马里最近的调查结果是由各种报告和国家统计局数据提供的。大多数时候,这些数据并没有实现,所以这篇论文作为科学研究有其范畴和局限性。

本文主要研究了随机延迟微分方程数值方法的相容性和收敛性。作为重要数学模型的随机延迟微分方程广泛应用于经济学、生物学、医学等领域。由于很难获得随机延迟微分方程的显示解,构造适当的数值方法和研究数值解的性质成为既有重大理论意义又有实际价值的研究课题。第一章介绍了本文的主要研究工作。第二章叙述了随机积分和伊藤—泰勒展开的基本理论知识。第三章是本文的主要研究内容。首先,回顾了随机延迟微分方程解析解和数值解的基本理论。其次,研究了随机延迟微分方程θ-方法的相容性与收敛性。证明了如果方程系数满足全局Lipschitz条件、线性增长条件、转移项系数一、二阶导数的一致有界性、初始条件满足H(o|¨)lder连续性,则θ-方法是相容的;证明了如果方程系数满足全局Lipschitz条件、线性增长条件、初始条件满足H(o|¨)lder连续性、则θ-方法是收敛的,且收敛阶为12阶。最后,研究了隐式一步泰勒方法的收敛性。

Influence of Copper and Arsenic on Gold Recovery in the Yalea Deposit, Western Mali

Gold recovery process is well known. The following paper presents the problematic related to the influence of Copper and Arsenic on the recovery of gold in the Yalea deposit. Multielement tests (Au, Cu, As) carried out on 37 blocks made it possible to understand that there is a correlation between these elements. This correlation has been observed since the analysis of block models (the block model for Copper, block model for Arsenic and the block model for gold. These models have shown that the Yalea deposit areas with a high gold content correspond to areas of high copper content and arsenic. Those who made it clear that copper and Arsenic are tracing elements of Gold in the Yalea deposit. In this paper, the mineralurgical tests carried out on 28 blocks revealed that the copper and the arsenic content in the ore penalize the recovery of Gold (146 ppm for copper and 4710 ppm for Arsenic). The Yalea deposit was emplaced by several hydrothermal phases that reactivated the structures. These phases are responsible for the establishment of large quantities of copper sulphides. Copper and Arsenic are elements that have a considerable influence on the gold recovery in the Yalea deposit.

Analysis of Indigents Selection by the Community: A Construction Inequality

Health 2022年第5期14卷 599-616页

作者： sidibe Souleymane Ilboudo Bernard Drabo K. Maxime Health Science Training and Research Unit University Ouaga 1 Pr Joseph Ki-Zerbo Ouagadougou Burkina Faso National Institute of Public Health Burkina Faso Health Science Training and Research Unit Ouaga 1 University Pr Joseph Ki-Zerbo Health Science Research Institute CNSRT Ouagadougou Burkina Faso

Burkina Faso conducted a community selection of the indigent in eight health districts. The selection targeted 15% to 20% indigent per district. This study analyzed the data of this selection from the databases of the Ministry of Health. Descriptive analysis and time series modeling were performed. Indigents were predominantly female, heads of household were mostly elderly, and the average age of household members ranged from 21.9 to 29.8 years. The households were small. Indigents were mostly uneducated and employed. They all belonged to a given religious denomination, Muslims were the most numerous. The majority of the indigents were married and almost a quarter of them were widows. About 2% to 17% of indigents were selected depending on the district. Forecasts showed both an increase and a decrease in the use of health care by indigents. The study recommends considering the poverty level specific to each district when selecting, strengthening education policies targeting the indigent, improving the socio-health conditions of the indigent including specific actions considering age, sex and marital status, and the formulation of an employment policy targeting the indigent. Analyzes of the relationship between poverty and religion may allow the exploitation of religious capital for the benefit of the indigent.

研究目的本研究旨在调查马里和塞内加尔妇女对避孕药具使用的知识、态度和做法,探讨影响其使用避孕方法的主要因素,特别是妇女想要的儿童数量,从而为更适当的计划生育干预措施提供证据基础。研究方法本研究于2018年期间,通过方便抽样方法,在马里南部和塞内加尔抽取16-50岁的育龄妇女602名,采用结构化问卷进行调查。由于此两国识字率低,部分调查使用了现场结构化访谈。研究结果马里的298名受访者和塞内加尔的304名受访者完成了问卷调查或结构化访谈。这两个国家的大多数受访者（马里为77.9%,塞内加尔为85.9%）都了解计划生育方法,且都对计划生育持积极态度。受访者认为,丈夫的压力是他们想要更多孩子的主要原因（50.3%的马里样本和45.4%的塞内加尔样本）。在塞内加尔和马里的调查对象中,使用现代避孕药具主要和“是否与丈夫讨论过避孕有关”（马里样本OR=5.595%,可信区间2.9-10.7,p＜0.001;塞内加尔样本OR=27.895%,可信区间13.1-59.2,p＜0.001）。研究结论尽管马里和塞内加尔的受访者都了解计划生育并对计划生育持积极态度,但在生育率较高的这两个国家,计划生育方法的使用率仍然较低。而一些社会和文化因素导致两国之间存有差异。其中,丈夫参与计划生育似乎是影响计划生育运用的重要因素之一。
