高风险系统组织因素分类与绩效评价

在收集以组织绩效评价、人的可靠性和人误分析为目的的两类组织因素分类的基础上,结合问卷调查,并依据建立的概念上的组织因素分类框架,从组织的目标和战略、组织结构、资源、规程、管理功能、培训、交流、组织文化等方面确立组织因素分类指标,基本克服了传统的组织因素分类缺陷。同时,依据组织因素的分类,考虑到组织绩效评价的复杂性和不确定性,采用模糊决策方法对某组织的绩效进行评价,识别出该组织现存的主要缺陷:组织管理方面的问题以及组织的结构设计不太合理等问题。     

Contribution to the characterisation of eco-design projects

Lots of eco-designed projects were carried out successfully, and eco-designed products are now on the market. However, it is very difficult for designers and engineers to compare their design projects to those already done and consequently to reuse the knowledge gained. In a more general perspective, a method to take advantage of previous experiences in eco-design is needed. This paper is a contribution to develop a standard for eco-design practices and proposes a framework to characterise both eco-design projects and eco-tools. Forty case studies from the literature were exploited to extract criteria and options to define the framework. The proposed usage-oriented classification of eco-tools, associated with the practical analysis frame of the design projects, was implemented and finally robust enough to characterise 40 projects.     

对我国大气污染物总量控制与排放标准的再认识

以我国现行的《大气污染防治法》为依据,通过理论分析,从总量控制与排放标准的控制目的、法律依据、制定部门、适用条件、适用对象、实施部门、法律责任等方面研究了二者的区别及联系,提出了在实际工作中的应用原则建议。     

浏阳农业结构类型及可持续发展的技术对策

根据农业自然资源特点、经济发展水平和生态环境状况,建立了区域农业结构类型的划分方法,把区域农业结构划分为8种类型。运用这一划分方法,对浏阳市农业资源、经济与生态结构类型进行了划分,结果表明,浏阳属于农业自然资源相对短缺、经济相对发达和生态环境状况相对较差的农业结构类型。在此基础上,用定位分析方法分析了浏阳市区位、资源位、经济位和生态位特点,对15种农业生态系统模式的效益状况进行了对比分析。根据农业发展现状,针对资源利用、产业发展及生态环境方面存在的问题,提出了实现农业可持续发展的技术选择:劳动密集型技术、品种资源改良与优良农业生物资源的引进、农产品加工及深加工技术、无公害、绿色和有机食品开发利用技术、旅游资源开发利用技术及废弃物资源化利用技术。     

石灰和石灰石湿法脱硫系统运行控制指标探讨

International Comparison of Occupational Safety and Health Research—A Review Based on Published Articles

A comparison of international literature in occupational safety and health (OSH) research over the years from 1980 to 1998 was conducted. The comparison is based on the different languages of the over 35,000 articles, which were collected from different databases. The distribution of languages in the analyzed data has to be considered carefully with respect to the original purpose of the data collection and the specific role of the international publication language, English. The comparison shows that in several aspects OSH research does not differ in different publication languages. In some methodological aspects, and in specific objects of research, differences between articles published in different languages can be found.     

Parallel and Serial Methods of Calculating Thermal Insulation in European Manikin Standards

Abstract

Standard No. EN 15831:2004 provides 2 methods of calculating insulation: parallel and serial. The parallel method is similar to the global one defined in Standard No. ISO 9920:2007. Standards No. EN 342:2004, EN 14058:2004 and EN 13537:2002 refer to the methods defined in Standard No. EN ISO 15831:2004 for testing cold protective clothing or equipment. However, it is necessary to consider several issues, e.g., referring to measuring human subjects, when using the serial method. With one zone, there is no serial-parallel issue as the results are the same, while more zones increase the difference in insulation value between the methods. If insulation is evenly distributed, differences between the serial and parallel method are relatively small and proportional. However, with more insulation layers overlapping in heavy cold protective ensembles, the serial method produces higher insulation values than the parallel one and human studies. Therefore, the parallel method is recommended for standard testing.
