Development of a 3D risk analysis technique for fire disaster and its application on accident simulation of a public site

In this research, we constructed a three-dimensional fire risk analysis technique (3D-FRAT) for common building fires. To demonstrate its effect, the 3D-FRAT employed a self-developed 3D risk-calculating module in combination with the Fire Dynamics Simulator (FDS) software to simulate the Welcome Restaurant accident that happened on February 15, 1995 in Taichung City, Taiwan. This study only focuses on thermal radiation and provide a preliminary method to quantify a fire risk. Different firefighting equipment that comply with the related building and fire-preventive regulations have been used in the simulations to test their mitigating effectiveness on the accident. The results were shown by animation, 3D pictures, and sliced pictures to facilitate the researchers’ understanding of human hazards caused by thermal radiation or smoke in a specific fire accident. The minimal personnel escaping times for different hazardous factors were estimated; various firefighting designs that can reduce loss of human life and property were also perused. According to the simulation results, the individual risk values in Welcome Restaurant were between 3.108 × 10⁻⁹ to 2.719 × 10⁻⁵ (deaths/year). It is foreseeable that the 3D-FRAT can become a useful tool for related organizations to choose better fire-resistant buildings or fire-fighting equipment in the future.

无机抗菌剂在建筑涂料中的应用研究

研究了5种无机抗菌剂：锌型沸石抗菌剂、银型沸石抗菌剂、氧化锌晶须复合抗菌剂、纳米TiO2光催化抗菌剂和Ca10-x-yTixZny（PO4）6（OH）2复合抗菌剂在涂料中的应用.以对大肠杆菌（E.coli）的灭菌效果评价抗菌性能.结果表明：锌型抗菌涂料的抗菌效果较差,后4种类型抗菌涂料具有很好抗菌效果.但是,银型抗菌剂和氧化锌晶须复合抗菌剂在涂料中存在易引起涂料变色和难分散问题;纳米TiO2光催化型抗菌剂在涂料中易加快涂料老化;而Ca10-x-yTixZny（PO4）6（OH）2复合抗菌剂既具有良好的抗菌性能,又对涂料的基本性能没有影响,它能够应用到抗菌涂料中.

Using Dynamic Modeling to Scope Environmental Problems and Build Consensus

/ This paper assesses the changing role of dynamic modeling for understanding and managing complex ecological economic systems. It discusses new modeling tools for problem scoping and consensus building among a broad range of stakeholders and describes four case studies in which dynamic modeling has been used to collect and organize data, synthesize knowledge, and build consensus about the management of complex systems. The case studies range from industrial systems (mining, smelting, and refining of iron and steel in the United States) to ecosystems (Louisiana coastal wetlands, and Fynbos ecosystems in South Africa) to linked ecological economic systems (Maryland's Patuxent River basin in the United States). They illustrate uses of dynamic modeling to include stakeholders in all stages of consensus building, ranging from initial problem scoping to model development. The resultant models are the first stage in a three-stage modeling process that includes research and management models as the later stages.KEY WORDS: Dynamic modeling; Scoping; Consensus building; Environmental management; Ecosystem management; Policy making; Graphical programming languages
