Internet tools in the medical classroom

Summary: The Internet contains a vast amount of medically relevant information. In order to access this information, however, many networks require one to master applications written in UNIX, an operating system considered by many not to be user friendly. Although these tools may be available on the campus, it is difficult to teach their use unless there is some immediate benefit to the already busy user. From that standpoint, it is important for instructors to realize that common UNIX applications can be utilized as classroom tools to significantly enhance the learning experience by facilitating teacher/student communication. Also, whilst the student enjoys greater communication with the instructor (and with other students) he/she is also becoming adept at using information management tools.     

Cognitive processes involved in the appraisal of stress

Four experiments were organized around a central question: What is the form of relationship between estimated stress level on the one hand and situation strain, personal resources and social support, on the other? The first experiment examined the form of the relationship between estimated level of stress, situation strain and personal resources. The participants were students. They integrated situation strain and personal resources information in a non‐additive way. In particular, the effect of personal resources on the estimated level of stress varied as a function of the level of situation strain considered. When the situation strain was low, the stress level related with this circumstance largely depended on the personal resources of the individual. When the situation strain was high, the stress level related with this circumstance was much less dependent on the personal resources of the individual. The second experiment replicated these results among first‐aid workers, fire‐fighters and persons that had recently been injured. The third and fourth experiments replicated these results in various conditions differing as regards the level of social support. Copyright © 2002 John Wiley & Sons, Ltd.     

大型医院病案信息化的管理与实践

病案作为医学临床信息的重要载体，只有将其进行海量存储、快速查阅、远程传输，使之活跃起来，才能真正地满足医疗、教学、科研和管理的需要。将传统的纸质病案进行扫描后保存为光盘，并存入光盘镜像服务器中，实现了网上实时访问、检索、查询、浏览和传输功能，并可以利用病案管理软件进行相应的统计和分析。为医疗信息资源进一步开发和利用，探索了一条大型医院病案信息化管理的有效途径。     

应用地理信息系统分析中国肾综合征出血热的空间分布

目的　利用地理信息系统 (GIS)技术分析中国大陆肾综合征出血热 (HFRS)的空间区域分布 ,建立HFRS危险区域分布图。方法　收集中国 41个HFRS监测点 1 995～ 1 998年的人群发病资料建立数据库 ,以中国省级、县级、一级河流数字地图为背景 ,在ArcGIS软件的支持下 ,与建立的数据库关联并对监测点人群发病资料进行反距离权重插值分析 ;收集 1 998年 6月SPOT4卫星覆盖东南亚地区的植被影像 ,逐一提取出各监测点监测区域的归一化植被指数 (NDVI) ,与 1 995～ 1 998年HFRS监测点人群平均发病率进行相关分析 ;根据不同流行强度监测区域的NDVI值 ,对遥感影像使用不同的颜色进行密度分割。结果　HFRS监测点人群发病资料的空间分析预测模型显示 ,中国HFRS主要分布于黑龙江流域、黄河中下游地区、长江中下游地区及京杭大运河 淮河流域地区 ,与1 995～ 1 998年全国各县HFRS平均发病率分布图进行比较 ,发现两者基本一致 ;相关分析显示HFRS发病率与NDVI之间呈现正相关 (r=0 .41 7,P <0 .0 1 ) ,根据各监测点NDVI的差异建立了中国HFRS危险区域分布图。结论　根据监测点数据采用GIS技术建立的预测模型对预测全国HFRS的分布情况有重要意义
