北京市三种典型城市绿地类型的保健功能分析

随着城市化进程的加快,越来越多的城市居民的健康受到城市污染的影响,因而城市绿地对人体的保健作用日益受到重视。通过实地监测的方法,选择北京3种典型类型的绿地、在不同空间以及不同的季相条件组合下,对形成绿地保健功能的空气负离子浓度、空气温度、湿度、二氧化碳浓度、噪音等因子进行了研究。结果表明：（1）不同绿地类型的保健功能有较大的差距,以同一时段空气中的负离子浓度为例,其最大值发生在郊野公园（1810cm^-3）,高于单位绿地（980cm^-3）,远高于作为对照的商业中心（110cm^-3）;（2）在同一绿地的不同空间位置也存在明显差异,以道路绿化防护林带为例,林带中心空气中的负离子浓度高达1900cm-^-3,高于林缘（591cm^-3）和林外（120cm^-3）;（3）同一绿地保健功能随季相变化发生明显改变,在有叶期的道路绿化防护林带中心的空气负离子浓度（1900cm^-3）是落叶期相同位置空气中负离子浓度（750cm-^-3）的两倍多。空气温湿度、噪音、CO2浓度的空间和时间上的变化类似于空气负离子。本研究获得的数据支持了城市绿地保健功能理论,可为合理设计城市绿地增强其保健功能提供依据。     

基于二元语义的职业健康安全管理体系绩效评价

为提高职业健康安全管理体系(OHSMS)绩效和职业健康安全绩效,根据OHSMS绩效评价的重要性,提出基于二元语义的OHSMS绩效评价模型。研究科学合理的评价指标体系,并运用层次分析法(AHP)和灰色关联分析法(GRA)确定主客观权重,再运用乘法集成法确定组合权重,作为评价指标的最终权重,运用二元语义的集结算子,计算OHSMS绩效评价指标的综合值,取得最终的评价结果。结果表明,基于二元语义的OHSMS绩效评价将专家经验与定量计算相结合,合理地处理许多因素的不确定性,通过确定不符合项和改进措施,持续改进OHSMS绩效。     

Acciphilia on the road: An analysis of severe collisions

Introduction

Although prior studies of road traffic accidents have found between-group differences in risk, little attention has been given to the encounter between drivers involved in severe collisions.

Method

The present study empirically evaluates two different possible causes of "social accidents," which are defined as collisions between two or more drivers where some faulty social interaction might be assumed, and which are the most prevalent cause of road injuries. The analyses use merged Israeli collision records from 1983 to 2004 with data from two national censuses, thus providing an unprecedented empirical basis to study the social foundations of car accidents. The data are used to adjudicate between two alternative hypotheses: the heterogeneity hypothesis (socially different drivers tend to collide) versus the homogeneity hypothesis (socially similar drivers tend to collide).

Results

Multivariate analyses provide preliminary support for the latter hypothesis. Given an accident, there are more collisions among drivers from the same broad educational group, and the factors that influence this correlation are independent of geography. The paper thus leads to the idea that severe collisions reflect a sociological or ecological process that is akin to acciphilia.

Impact on Industry

The preliminary findings suggest that variation between drivers may be preferable to similarity, since apparently there is a greater tendency toward collisions between similar drivers.     

Evaluating repeated patient handling injuries following the implementation of a multi-factor ergonomic intervention program among health care workers

Objective

The objective of this study was to evaluate repeated patient handling injuries following a multi-factor ergonomic intervention program among health care workers.

Methods

This was a quasi-experimental study which had an intervention group and a non-randomized control group. Data were collected from six hospitals in Saskatchewan, Canada from September 1, 2001 to December 1, 2006.

Results

A total of 1,480 individuals who had a previous injury were eligible for the study. Medium and small size hospitals in the intervention group had significantly fewer repeated injuries than in the control group. Multivariate analysis showed that the intervention group had 38.1% lower odds of having repeated injury compared to the control group, after adjusting for hospital size.

Conclusions

The work-related repeated injury after a multi-factor intervention program was reduced. The synergistic relationships between components of multi-factor intervention and applicability of injury prevention programs to different settings need to be further explored.

Impact on Industry

Implementing a multi-factor program with the right equipment and training can lower the risk of injury among health care workers.     

Falls and fall prevention programmes in developing countries: environmental scan for the adaptation of the Canadian Falls prevention curriculum for developing countries

Problem

Falls in older persons in developing countries are poorly understood, and falls prevention and health promotion programmes for this population are largely lacking.

Methods

A systematic review was carried out of relevant literature on falls and prevention programmes, and falls prevention education, and a scan undertaken of health promotion programmes for older persons in a representative country - South Africa.

Results

Studies on the risk and prevalence of falls are largely retrospective and hospital-based, with varied methodology, including study period, sampling method and sample size. Falls prevalence is based largely on self-reports in studies on general trauma in all age groups. Falls incidence varies from 10.1% to 54%. No reports could be traced on sustained falls prevention or health promotion programmes.

Conclusion

Scant research has been conducted and little preventive education offered on falls in older persons. Adaptation of the Canadian Falls Prevention Curriculum for developing countries will help to fill gaps in knowledge and practice.

Impact on industry

With rapid increase in the populations of older persons in developing countries, research on age related disorders such as falls is required to guide policy and management of falls.
