基于Web的安全评价辅助系统的研究

随着我国经济的迅速发展,安全生产的问题在国民经济中的地位越来越重要,安全评价工作正在各个行业开展。目前,对系统安全状况的评价主要通过人工方式,其主要缺点有评价数据精度不高、评价速度慢、评价操作复杂等。本文设计了一个适合政府部门和企业的安全评价辅助系统。将计算机技术应用于安全评价过程中,较好的克服了人工方式的缺点,并能将评价信息及时完整的反馈给安全工作者。该系统运用MicrosoftSQLServer2000和．NET技术,构建了基于B／S／D／C结构的安全评价辅助系统平台,实现了安全评价报告的撰写等功能。其具有一定的实用性,能满足一般用户对安全评价报告的撰写、快速浏览添加以及统计管理等功能。

过氧化氢热爆炸研究进展

过氧化氢作为绿色环保的氧化剂,广泛应用于工业的各个领域,同时也因其热分解爆炸危险性导致了一系列严重的火灾爆炸事故。过氧化氢在高温或与一些不兼容化学物质作用下,将会激发其热危险性,进而引发热失控反应,最终导致爆炸事故的发生。结合近年来国内发生的过氧化氢热爆炸事故,简要概述了其热爆炸事故历程,并从理论研究和实验研究两个方面综述了过氧化氢热爆炸的研究进展。理论研究方面,主要介绍了化学反应失控模型和基于热动力学的研究方法,尤其对基于热失控模型的热风险评估进行了详细的阐述。实验研究方面,分析了高温条件下与杂质催化作用下过氧化氢的热危险性,包括无机杂质和有机杂质。最后就过氧化氢热爆炸的研究提出了进一步的研究方向。

Implementing falls prevention research into policy and practice in Australia: past, present and future

Introduction

Falls in older Australians are a significant public health issue with one in three older people falling one or more times each year.

Method

Many fall prevention randomized controlled trials have been conducted in Australia as well as across the world.

Results

The findings of these studies now constitute a substantial evidence base that can provide direction for health and lifestyle interventions for preventing falls in older people. This research evidence has contributed to health policy in Australia to some extent, but is yet to be widely implemented into practice. This opinion piece overviews previous policy initiatives and describes a new Partnership research program funded by the Australian National Health and Medical Research Council (NHMRC), which seeks to further influence health policy and address the ongoing research-practice gap.     

Using the RE-AIM framework to translate a research-based falls prevention intervention into a community-based program: lessons learned

Problem

Exercise-based research interventions demonstrate reduced risk and rates of falls for community dwelling older adults; however, little is known about effective mechanisms for the translation, implementation, and maintenance of these interventions in community settings.

Method

The RE-AIM framework was used to assess the translatability of an effective exercise-based research intervention in a community setting. Questions included: Reach — Would the target population attend? Effectiveness — What was the adherence and compliance to the program? Were there individual improvements in falls risk factors? Adoption: Would staff at the center adopt the program and offer it past the funding period? Implementation — What adaptations, including optimal frequency and duration, should be made to meet the community needs, still adhere to core elements and achieve similar outcomes? Maintenance — Would the program be sustained by our community partners?

Discussion

The process of translating a controlled research intervention targeting older adults at risk of falls into a community setting was challenging. Licensed professionals developed the infrastructure to safely and effectively deliver the program. The end product was highly appealing program to our target audience, resulted in improved outcomes and was successfully adopted and maintained by the community partner.

Summary

Partnerships between community and healthcare providers are key to successful implementation of falls prevention interventions. Lessons learned from this experience can be applied to the translation of future exercise-based falls prevention interventions.     

基于概率影响图的R&D项目风险传导评估模型

为实现R&D项目风险的有效管理,需要对风险的传导特性进行量化评估。基于传导能量理论,利用概率影响图方法,从拓扑层、函数层和数值层构建了R&D项目风险传导评估模型。分析表明:该模型对项目风险传导量化研究具有较强的适用性;数据采集简便,模型的评估精度取决于信息的完全性;通过应用过程中的模型简化,在一定程度上能够提高模型的实用性。最后考虑项目管理者的决策因素,在评估模型基础上设计了R&D项目风险传导评估框架。
