Arabian,Asian, western: a cross-cultural comparison of aircraft accidents from human factor perspectives

Introduction. Rates of aviation accident differ in different regions; and national culture has been implicated as a factor. This invites a discussion about the role of national culture in aviation accidents. This study makes a cross-cultural comparison between Oman, Taiwan and the USA. Method. A cross-cultural comparison was acquired using data from three studies, including this study, by applying the Human Factors Analysis and Classification System (HFACS) framework. The Taiwan study presented 523 mishaps with 1762 occurrences of human error obtained from the Republic of China Air Force. The study from the USA carried out for commercial aviation had 119 accidents with 245 instances of human error. This study carried out in Oman had a total of 40 aircraft accidents with 129 incidences. Results. Variations were found between Oman, Taiwan and the USA at the levels of organisational influence and unsafe supervision. Seven HFACS categories showed significant differences between the three countries (p?<?0.05). Conclusion. Although not given much consideration, national culture can have an impact on aviation safety. This study revealed that national culture plays a role in aircraft accidents related to human factors that cannot be disregarded.     

邛海水质变化趋势及保护对策研究

本文通过对邛海流域现状污染源进行调查,邛海流域COD、氨氮、总氮和总磷产生量分别为5892.1t/a、995.6t/a、2888.2t/a和1105.1t/a,污染负荷主要来自面源污染.通过2002 ～ 2011年邛海水质监测数据分析,邛海水质近10年总体保持Ⅱ～Ⅲ类,处于中营养状态,2004～ 2006年水质相对较差,2006年以后水质逐渐好转.总磷、总氮是邛海主要污染因子,海河口是邛海污染最严重的区域.为实现邛海水质和流域生态环境持续改善,从产业结构优化、流域污染源治理、生态保育和流域生态环境综合监管等方面提出对策建议.     

监控完全遮挡场景下火焰特征分析方法*

为解决监控完全遮挡场景下火灾原因认定面临的问题,探究火焰的视频特征分析方法。利用油盘火、垃圾桶火焰和短路火花3种实体火焰模拟室内火灾,布置普通彩色CCD监控摄像头使之被完全遮挡,收集火灾视频进行预处理,利用视频分析技术提取、对比、分析油盘火焰、垃圾桶火焰和短路火花的HSV颜色、火焰面积增长、质心变化、Harris角点变化、火焰频闪等特征,并总结对应特征变化规律。结果表明:在监控完全遮挡场景下,提出的火焰视频特征分析方法可以较为精确地定量表征火焰动静态特征,为火灾调查工作的顺利开展提供有力的工具。

Current Status of Manufacturing Hazardous Waste in Shanghai

Abstract

It is difficult to manage the manufacturing hazardous waste (MHW) which is generated from a huge amount of complicated sources and causes very serious pollution. Therefore more and more attention has been paid to MHW pollution. Shanghai, as an industrial and economic center and an international metropolis in China, has a vast industrial system spanning a multitude of sectors, which generates MHW not only in a huge magnitude but also in a large variety of types from complicated sources, resulting in severe pollution. In 2003, the production of MHW in Shanghai is about 3.96 × 10⁵ ton, involving 33 indices. Most of MHW in Shanghai is treated and disposed of, but a significant portion is not handled properly and effectively. This paper carries out in-field investigation on the current status of MHW production and treatment in Shanghai, and puts forward scientific proposals that Shanghai should facilitate cleaner production and minimize hazardous waste; strictly enforce hazardous waste registration system, strengthen monitoring the certified enterprises; strengthen intent disposal center construction and realize hazardous waste reclamation; accelerate establishing the technical criteria and the management policy, promote the research and development on the treatment and disposal technology, and strengthen information management, thus realizing integrated management on MHW pollution.     

Migrating an incident reporting system to a CCPS process safety metrics model

A major chemical company established a formal incident investigation and reporting system several years ago. The original system focused heavily on worker-related injuries, illnesses, and near-misses and was used primarily to track statistics reportable to the Occupational Safety and Health Administration (OSHA). This Occupational Injury and Illness (OII) approach has been recognized to be an ineffective tool for measuring, predicting, and preventing process safety incidents. The Center for Chemical Process Safety (CCPS) recently published guidelines on how to establish safety metrics for the measurement and reduction of process safety incidents. The process safety metrics approach relies upon leading and lagging metrics to improve organization process safety. This paper is a case study of the analysis of one organization’s incident database, which represents approximately five years of data from over a dozen facilities. The aim of this investigation was to extract useful process safety metrics from the incident investigation and reporting system, which would be pertinent to the types of process units and process functions at these facilities. This paper will discuss the approach taken to extract process incident information from an OII-based database and present the difficulties of performing an analysis on such a database. This paper provides guidance on how to migrate an existing OII-based reporting system to a program that includes process safety metrics in accordance with industry best practices.
