医院信息系统网络安全分析与对策

随着计算机技术的不断发展,医院信息系统开始普及,网络安全问题已经成为各个医院信息化建设中不可忽视的首要问题。本文结合我院实际情况,提出了医院信息系统网络安全应对策略。     

医院冬季空调工况热湿舒适需求分析

为研究医院建筑室内人员对热湿环境的舒适需求,对重庆市某医院冬季空调病房中病员与健康人员的热湿感觉、整体舒适感进行了现场调查和室内热湿参数测试。采用Bin法划分温湿度区间,将各区间内的平均温度与平均热感觉投票、平均相对湿度与平均湿感觉投票进行线性回归分析,得到病员的中性温度为20.4℃,认为适宜的相对湿度为57%;健康人员的热中性温度为18.8℃,而其对于湿度的要求较高。且发现病员对温湿度变化的敏感度高于健康人员。最后推荐给出了冬季医院病房的舒适性温度范围为20-23℃,相对湿度范围为40%～60%,为重庆地区医院病房的空调设计及控制提供了参考。     

WSUS补丁分发系统在医院内网中的应用

针对与互联网物理隔离的医院内网计算机操作系统无法自动更新的问题,提出应用微软的免费软件WSUS来实现医院内网计算机补丁自动更新。通过对WSUS系统在医院内网中的部署和应用的详细介绍,为有效地避免因系统漏洞引起的病毒爆发和恶意攻击提供了一种思路,在减少维护工作量的同时也提高了医院内网的安全性。     

Bacterial population changes in hospital effluent treatment plant in central India

Hospital effluent with its high content of multidrug resistant (MDR) enterobacteria and the presence of enteric pathogens could pose a grave problem for the community. It was planned at our tertiary care hospital in central India to study the population changes at various steps of effluent treatment plant (ETP) like collection, aeration, clarification, liquid sludge, dried sludge, high-pressure filter and treated wastewater. The study included viable bacterial counts, coliform counts, staphylococcal, enterococcal, Pseudomonas and multiple drug resistant (MDR) gram negative bacterial counts in the different stages of ETP. In order to study the distribution of bacteria as free floating in liquid and adherent to suspended particles, enumeration of the bacteria in the filterate and the sediment was also carried out. The effluent input showed 55% of the 8.6 x 10(6)/ml bacteria as coliforms and E. coli which was a typical of fecal flora. The prevalence of MDR coliforms was 0.26%. The substantial reduction (> 3log) was seen for the effluent coming from the clarifier. The bulk of the bacteria in the hospital effluent remains firmly adhered to solid particles; aeration and clarification removes bulk of the bacteria by physical processes like flocculation. The treated liquid effluent still contains sizeable loads of MDR bacteria and inactivation by procedure such as chlorination is required. The bacteria get concentrated in sludge and a greater concentration of chlorine is required for decontamination.

Prototyping virtual reality serious games for building earthquake preparedness: The Auckland City Hospital case study

Enhancing evacuee safety is a key factor in reducing the number of injuries and deaths that result from earthquakes. One way this can be achieved is by training occupants. Virtual Reality (VR) and Serious Games (SGs), represent novel techniques that may overcome the limitations of traditional training approaches. VR and SGs have been examined in the fire emergency context; however, their application to earthquake preparedness has not yet been extensively examined.We provide a theoretical discussion of the advantages and limitations of using VR SGs to investigate how building occupants behave during earthquake evacuations and to train building occupants to cope with such emergencies. We explore key design components for developing a VR SG framework: (a) what features constitute an earthquake event; (b) which building types can be selected and represented within the VR environment; (c) how damage to the building can be determined and represented; (d) how non-player characters (NPC) can be designed; and (e) what level of interaction there can be between NPC and the human participants. We illustrate the above by presenting the Auckland City Hospital, New Zealand as a case study, and propose a possible VR SG training tool to enhance earthquake preparedness in public buildings.     

企业医院改制后经营管理战略的思考与探讨

企业医院从企业离剥改制后,要由封闭式的单纯福利型管理向开放式的经营管理型转变,成为相对独立的医务劳动生产者和经营者,如果对于将来没有一个长期的明确的方向,对于眼前出现的困境束手无策,就难于在新的技术和经济的大变革中继续生存下去,因而制定正确的经营管理战略就至关重要。在实践中,一要探析内外环境,把握发展方向;二要结合内外实际,理清战略思路;三要深化内部改革,推动战略实施。     

一道幂指函数求极限题目的多种解法

极限理论是微积分教学中的重要内容。由于幂指函数是一种特殊的函数,对幂指函数求极限往往是比较复杂的问题。以一道幂指函数题目为例,分别使用定值法、等价无穷小代换法、洛必达法则三种方法来求解。通过一题多解,总结出幂指函数求极限的常用方法,以供教学参考。
