预负荷系数对三油楔径向滑动轴承稳定性的影响

以三油楔径向滑动轴承为研究对象,采用M atlab语言进行编程,对二维R eyno lds方程离散化数值求解,探讨了预负荷系数对三油楔径向滑动轴承稳定性的影响。得出了三油楔径向滑动轴承稳定性在不同偏心率和宽径比下随轴承预负荷系数的变化而变化的一系列规律性曲线,并进行了理论分析。

439家公共场所禁烟情况监督检查结果分析

目的检查公共场所贯彻执行《上海市公共场所禁止吸烟暂行规定》现状。方法对439家公共场所禁烟专项执法检查结果进行分析。结果部分公共场所(如游艺厅(室)、歌(舞)厅、音乐茶座室)禁烟情况明显比其他法定禁烟场所差。结论在公共场所禁烟执法检查中,针对重点场所,在加强执法检查的同时,要督导开展禁烟宣传教育,同时完善控烟制度,落实禁烟设施。     

国境口岸突发公共卫生事件应急预案框架体系的构建

[目的]提高政府保障公共安全和处置突发公共卫生事件的能力,最大程度地预防和减少突发公共卫生事件及其造成的损害,保障公众的健康和生命财产安全,维护国家安全和社会稳定,促进经济社会全面协调、可持续发展。[方法]结合国境口岸应对突发公共卫生事件的实际情况,从3个方面对如何构建国境口岸突发公共卫生事件应急预案框架体系进行了研究。[结果]构建国境口岸突发公共卫生事件应急预案框架体系应包括构建框架体系的准则、框架体系内容、编制框架体系应把握的要点。[结论]构建国境口岸突发公共卫生事件应急预案框架体系对于提高检验检疫机构预防和处置口岸突发公共卫生事件的能力,全面履行卫生检疫行政职能具有十分重要的意义。     

Are Essential Medicines in Malaysia Accessible, Affordable and Available?

Objective: To assess the pharmaceutical sector to know whether people have access to essential medicines. Setting: The study was conducted in 20 public health clinics, five public district drug stores and 20 private retail pharmacies selected randomly in five different areas randomly selected (four states and a federal territory). Method: The methodology used was adopted from the World Health Organization study protocol. The degree of attainment of the strategic pharmaceutical objectives of improved access is measured by a list of tested indicators. Access is measured in terms of the availability and affordability of essential medicines, especially to the poor and in the public sector. The first survey in the public health clinics and public district drug stores gathered information about current availability of essential medicines, prevalence of stock-outs and affordability of treatment (except drug stores). The second survey assessed affordability of treatment in public health clinics and private retail pharmacies. Main Outcome Measure Availability, stock-out duration, percent of medicines dispensed, accessibility and affordability of key medicines. Results The average availability of key medicines in the public health clinics for the country was 95.4%. The average stock-out duration of key medicines was 6.5 days. However, average availability of key medicines in the public district drug stores was 89.2%; with an average stock-out duration of 32.4 days. Medicines prescribed were 100% dispensed to the patients. Average affordability for public health clinics was 1.5 weeks salary and for the private pharmacies, 3.7 weeks salary. Conclusions: The present pharmaceutical situation in the context of essential medicines list implementation reflected that the majority of the population in Malaysia had access to affordable essential medicines. If medicines need to be obtained from the private sector, they are hardly affordable. Although the average availability of essential medicines in Malaysia was high being more than 95.0%, in certain areas in Sabah availability was less than 80.0% and still a problem.     

电话网络心电模式在社区基础医疗的应用

目的:探讨电话网络心电模式在社区基础医疗的应用效果。方法:对社区医院的142例有心脏不适症状而普通心电图多次检查均正常的患者进行电话网络心电监测(TTM)1056次,通过电话和网络传送心电信息至本院心脏监测中心,专职人员分析、诊断和出具报告,指导患者用药和治疗。结果:142例患者中发现早期心肌梗死心电图改变者1例,缺血型ST-T改变者16例,阵发性室上速22例,阵发性房颤12例,间歇性预激综合症8例,房性早搏和(或)室性早搏35例,6例安装永久起搏器和14例冠状动脉支架置入(PCI)术后患者TTM监测无新的异常出现,28例未见异常。结论:TTM监测能及时将平时心电图、Holter等难以捕捉的心电信息记录下来,为临床诊断和治疗提供有效依据,为患者提供早期诊断心脏病的检查手段。     

The potential health impacts of climate change: An overview

Climate change would have a range of impacts on human health. Health impacts would be caused by the direct effect of climatic factors on human health, such as heat stress, and possible changes in the frequency and intensity of extreme weather events such as storms, floods and droughts. Impacts on health would also be mediated by the indirect effects of climate change, such as changes in availability of food and water and the distribution of vector‐borne diseases. The majority of health impacts would be adverse and would depend greatly on the vulnerability of populations.
