劳动防护用品研制中的假人

一 假人是真人不可少或缺的替身 在劳动防护用品研制试验中,假人担负着重要的作用,许多情况下用假人模拟真人进行试验,是真人不可少或缺的替身。 1.试验具有较大的危险性或超出人体耐受极限:如阻燃服的燃烧试验;防辐射服装的辐射试验;保护头盔的碰撞试验等。 2.有些试验须先经假人试验阶段,再逐步过渡到真人试验:如阻燃服经假人的二度烧伤试验,暖体假人的隔热值试验,测得燃烧性能和舒适性能后,再由真人身着服装在     

职业适应性测试评价及应用

前言 随着科技的进步,经济的发展,工业自动化程度越来越高,人机系统越来越复杂,一方面虽然减轻了作业者的体力劳动负荷,但也增加了作业者的心理负荷,另一方面对作业者提出了新的和更高的要求。不同的职业(工种或岗位)具有不同的作业性质和特点,例如,我国“八五”科技攻关项目就将涉及重大危险装置操作的100多个工种划分     

Coping with riverbank erosion hazard and displacement in bangladesh: survival strategies and adjustments

As a deltaic plain, Bangladesh annually experiences riverbank erosion hazard due to sudden and rapid channel shifting, particularly in the major floodplain areas of the country. Consequently, valuable cultivable land is lost; also village settlements, markets and towns are destroyed, displacing tens of thousands of people. This paper examines the magnitude of river channel migration and encroachment on land, and the nature of human adjustment systems in the Brahmaputra–Jamuna floodplain, by investigating aspects of the social and cultural dynamics of resettlement of the displaced people. Some policy measures are recommended to improve the ability of the people in the floodplain to cope with these hazards.     

Design and validation of a practical index for trauma assessment

In the past 20 years a variety of indices have been suggested for measuring the severity of trauma, however none of them meets the requirement of being a simple and objective instrument that can be utilized efficiently by lay persons and providers of health services without previous experience in triaging. A new system has been proposed which meets this requirement and which has been validated with 197 injured persons at the emergency ward of the Valle University Hospital in Call, Colombia. The instrument showed a high level of concordance with the conventional triaging method and classifies victims into four categories: critical with recovery unlikely, critical but recoverable, moderately serious, and ambulatory. There is discussion on the reliability of this instrument and it is recommended that it be validated with victims from larger disasters. Regardless, it has the advantage of being specific and free of the subjectivity that characterizes other indices.     

The role of socio-economic data in food needs assessment and monitoring

This paper reviews six case studies examined as part of a project to review targetting methodologies employed by non-government organisations in Africa during the 1984-6 food crisis. Most agencies have not yet fully evaluated the role of data in informing policy decisions during their respective emergency programmes. The case studies presented reflect a wide variety of approaches to targetting emergency food aid that are based largely on the use of 'socio-economic' data. The recent emergency relief operations in Africa seem to indicate a change in relief agencies' approaches to the assessment and monitoring of needs of the affected populations. Earlier dependance on nutritional data has given way to an increasing reliance on the use of socio-economic indicators. There was a wide variation in the case studies of the type of indicators collected and utilised in needs assessment and monitoring. There were those who relied almost exclusively on nutritional data to target resources during the 1984-86 African crisis, and others whose experiences during that period lead them to attach more weight to socio-economic data. Other agencies appear to have recognised the problems of relying solely on nutritional data to target food aid during their 1984–86 emergency programmes, and thus more or less abandoned classical anthropometric surveys in their needs assessment and monitoring methodologies during this period. Thus nutritional data has a less significant role in the decision making process than previously had been the case.     

茅山地区玄武岩砾石层之新发现及其意义

笔者通过对茅山东侧断裂的追踪调查,在溧阳县什箦煤矿丫髻山之东南麓发现玄武岩砾石层.据现场考察,此砾石层位于上第三系玄武岩之上,出露高度50—100米.本文具体描述了玄武砾石层的性状特征,同时在与前人描述的"玄武砾石层"进行对比研究后认为:两者属于同时代产物,但岩性和结构不尽相同.文中还就此新发现,对茅山东侧断裂活动速率提出补充看法.     

The qiongshan earthquake of july 1605

In 1605 a destructive earthquake affected the northern region of Hainan Island and adjacent parts of the Chinese mainland. Based on a detailed analysis of contemporary chronicles, the authors present a revision of the effects of the earthquake, and show that a sequence of strong shocks throughout 1605 caused cumulative damage and relatively heavy loss of life in Qiongshan. The subsidence of large areas of coast round Puqian Bay and Dongzhai Port is shown to be due to a combination of liquefaction caused by the shock, the occurrence of a typhoon associated with flooding and exacerbated by a high surge tide, as well as a long-term process of active tectonic movement in the area; the subsidence was not caused by downthrow of the earth's crust during the shock. Topographical changes in the area, traced from historical maps, suggest that subsidence is continuing, but a survey of the long-term seismicity of Hainan Island indicates that it is not an area of exceptional seismic risk.     

Surveillance for adverse health effects following a chemical release in west virginia

On 11 August 1985, a large inadvertent release occurred from a chemical manufacturing plant in Institute, West Virginia. The emission was related to overheating of a storage tank that contained chemicals for the production of aldicarb, a cholinesterase inhibiting pesticide. As a result of this emission, 136 persons were treated in five local emergency rooms, 29 of whom were hospitalized for one or more days, mostly for observation. No fatalities resulted. Interviews with treated persons and non-treated community residents confirmed that the health effects were transient and compatible with exposure to irritating vapors rather than with exposure to methyl isocyanate (a chemical used in the process) or to aldicarb. Only 5% of the treated persons and 5% of the community residents surveyed were adequately warned of the emission by the plant siren. Because persons in the nearby community are potentially vulnerable to chemical injury, we recommend the development of an improved warning system, a formal evacuation procedure, and other measures to limit exposure of persons in this area in the event of a future release.

我国矿产资源态势与对策

我国矿产资源总量大,居世界第3位人均拥有量小,居世界第80位。我国要实现现代化建设的第二步战略目标,矿产资源供需存在着矛盾。为了解决供需矛盾,必须从地质找矿、矿山、一次资源回收、二次资源回收、节能和节材等方面挖掘潜力。改革资源耗费型经济发展旧模式,确立资源节约型经济发展新模式,废止“有水快流”的方针,确立开发与节约并重的方针,是缓解矿产资源供需矛盾的根本途径。具体对策有:(1)依靠科学技术进步开发节约(2)搞好资源进出口贸易取长补短(3)健全法制管理体系依法治矿(4)用好计划机制管好资源和矿山(5)用好市场机制搞活矿业经济。
