以天津市医疗废物管理现状为研究对象，对处置方式进行深入探讨，分析目前分散处置和集中处置存在的缺陷，提出“区域集中处置”设想；并运用模糊决策模型理论，建立较完善的处置方式评价指标体系，应用模糊综合评价模型得出“区域集中处置”是最佳的医疗废物处置方式，同时提出了相应的区域集中处置策略。     

几种医疗垃圾处理技术综述

医疗废物是一类危害极大的特殊废物。自20世纪50年代起,医疗废物的处理已引起世界各国的广泛重视。目前,国内外学者对医疗废物处理技术的研究日益丰富,已经取得了一定的研究成果。在此基础上,通过综合比较焚烧处理、高压蒸汽灭菌处理、化学处理、微波处理、热解处理等几种医疗废物处理技术,综合评定了各种处理工艺的技术参数及优缺点,最后比较分析得出了高温热解法具有多方面的优点,是目前国内外首推的医疗废物处理技术。     

Importance of awareness in improving performance of emergency medical services (EMS) systems in enhancing traffic safety: A lesson from India

Objective: India has been slow in implementing a central emergency medical services (EMS) system across the country. “108 services” is one of the most popular services that is functional under the public–private partnership model. Limited available literature shows that despite access to services, many traffic crash victims are transported using private vehicles. The objective of this study is to understand the effectiveness of 108 services from a traffic safety perspective.

Method: A questionnaire survey is conducted to understand the awareness of EMS and their function. Using traffic-related fatalities as the dependent variable, a fixed effect panel data model is developed to analyze the effectiveness of the 108 services in improving the traffic safety.

Results: The results from the survey show that, in general, people are not aware of the 108 services. A majority of the population prefers taking victims to the hospital using their personal vehicles or any other vehicles available compared to calling an ambulance. Results from panel data analysis show that despite having an efficient system, these services failed to make significant improvement in the safety of road users in the states in which their services were subscribed.

Discussion: The lack of awareness of an important safety service is alarming. This could be a major reason for lower utilization of 108 services for transporting victims of traffic crashes. This article shows the importance of having efficient awareness campaigns to improve the efficiency of any similar programs that are aimed to enhance the safety of a region.     

User involvement in the ergonomic development of a medical instrument: a longitudinal case study

In this study the focus is on the continuous ergonomic-focused development of a medical instrument that is capable of performing blood group serological tests. Primarily, a medical device must be clinically effective and safe. At the same time it must also meet the needs of its users. This calls for consideration of numerous ergonomic aspects. The development process of the product line in question was supported by a longitudinal series of carefully designed focus groups. Altogether, the 23 focus groups conducted included 245 participants from 72 laboratories. The aim of the empirical research was to collect users’ experiences, ideas and needs as inputs for the following phase of the product development process. During the mentioned focus group analyses, around 100 development proposals were conceived. Besides presenting more of the mentioned development proposals, the focus group analysis was shown as a proper methodology to involve end-users in the development and implementation of new technology or devices.     

块茎类作物对农村垃圾中铅镉等重金属的吸附研究

随着城市的快速发展,工业化越来越深入人心,很多交通、化工类的重金属污染产业也迅速发展起来,这些造成了农村垃圾中重金属的种类和含量都在不断攀升.由于大气、水源的传播以及通过农作物进入人体,污染的范围不断扩大,造成的危害也越来越严重.文章利用布点采样分析的方法,调查了污染不同区域的农村垃圾重金属污染状况,对数据进行统计分析,为政府部门正确判断与决策提供科学的依据.
