Differences in urban and rural accident characteristics and medical service utilization for traffic fatalities in less-motorized societies

Introduction

Fatalities from traffic accidents in less-motorized societies are an important global issue. We aimed to characterize the geographic differences of fatalities in such societies to facilitate the development of targeted interventions.

Method

This study linked police reports, hospital data, and vital registration data from Taiwan with special reference to accident factors in pre-hospital deaths and medical care in hospital deaths.

Results

A higher percentage of pre-hospital deaths were observed following rural as compared to urban traffic accidents. The deaths due to rural accidents can be attributed to lower use of restraints (i.e., helmets or seat belts), lower percentage of motorcyclists, and more highway accidents. A higher percentage of victims in rural accidents were transported to distant medical centers rather than to local hospitals.

Conclusion

Specific interventions, such as intelligent emergency medical systems, campaigns for helmets and seat belt usage, enforcement of helmets and seat belt use, and speed control measures should be targeted to rural areas.

Impact on industry

Cooperation between the vehicle industry and emergency medical providers in rural traffic accident rescue teams may decrease the numbers of deaths in these regions.     

Collaborative activity with business partners for improvement of product environmental performance using LCA

Collaborative activities with business partners have potential to improve environmental performance of product and life cycle assessment (LCA) is an essential technique to implement eco-design of product and production process. However, collection of LCA data from supply chain is a major issue for LCA practitioners. We propose a Supply Chain Collaboration Model (SCCM), which is a framework for collecting producer-specific LCA data from business partners and for promoting improvement activity of product environmental performance. We demonstrate the practicability of the SCCM using three case studies. In each case study, two or three partner companies organized a product improvement project and carried out process analysis techniques such as LCA and material flow cost accounting (MFCA). As a result, improvement activities from the economical standpoint could provide an incentive for business partners to collect LCA data, and thus the SCCM is an effective framework for eco-design.     

基于DEA的江苏省环境效率研究

运用DEA方法中SBM模型对江苏省13个地级市2001～2007年间环境效率及其变化率进行分析.结果显示江苏省各地级市间环境效率差异明显,苏州、无锡、常州、盐城和宿迁5市处于前沿面上,其他市均是DEA非有效或弱有效.Mahnquist指数计算显示各地级市在研究期内变化率不大,但扬州市近年来环境效率持续降低.综合经济产出...     

中国木材产业发展的阶段识别及时空分异特征

论文基于产业生命周期理论及探索性空间数据分析方法,运用1954—2014年各省木材产量数据对中国木材产业的发展阶段以及时空格局变化规律展开了分析。研究表明：1） Gompertz模型显示木材产业处于产业生命周期的成长阶段;2）探索性空间数据分析显示木材产业具有明显的地域转移趋势和显著的区域聚集特征,尤其在2000年以后,南方集体林区逐渐形成了木材生产“热点”;3）根据重心模型显示的移动轨迹,可以将木材产业发展分为三个时期,即经济驱动时期、经济驱动与生态驱动相持时期、生态驱动时期,木材产业的时空格局演变是这两种驱动力量相对均衡的结果。根据研究结论,提出了重视森林资源培育、适时放开采伐限额、由行政监督向购买社会服务转变等促进木材产业发展的建议。

数据采集在火焰闪烁频率的测量研究及分析中的应用

当可燃物燃烧时,产生的火焰通常具有一定的闪烁频率,并且每种可燃物都具有个自固定的闪烁频率,这种频率在火灾的危险度评估和火灾的监控中具有重要的研究价值.为了测量这些可燃物的火焰的闪烁频率,我们设计了数据采集系统,用多种可燃材料进行了大量的实验,研究了算法.经过处理和分析,得出了火焰闪烁频率分布在3-25Hz之间,主要频率在7-12Hz范围内,并且火焰闪烁频率与火焰大小和距红外接收器件的距离无关.基于以上结论,可以认为将火焰的闪烁频率作为判断火灾是否发生的判据是完全可以的.     

Identification of managerial shaping factors in a petrochemical plant by resilience engineering and data envelopment analysis

Resilience engineering (RE) is a novel approach that is capable of controlling and limiting incidents and accidents. This study identifies managerial shaping factors in a petrochemical plant by RE and data envelopment analysis (DEA). To do this, a standard questionnaire containing resilient factors is completed by managers of a petrochemical plant. Then, the best DEA model is selected based on average efficiency and statistical test. In addition, sensitivity analysis are performed to identify the most important shaping factors. Reporting culture, management commitment, and preparedness are identified as the most important factors in this paper, respectively. Finally, the proposed model is validated and verified through statistical experiment. The proposed approach would help managers to have a comprehensive understanding of the plant with respect to the RE. To the best of our knowledge this is the first paper that examines resilient shaping factors in a petrochemical plant with respect to management and organization by DEA.     

A new methodology for the synthesis of an optimum flexible water networks

This paper presents a new optimization model for the synthesis of direct reuse/recycle water networks with data uncertainties. In this case, data uncertainties were originated from the varying parameters of the water sources and sinks, which fluctuate within a given range of values. The aim of the method is to design an optimum flexible water network (FWN) that ensures minimum fresh water consumption and yet fulfilling all process constraints and uncertain parameters. The resulting FWN also features the minimum number of pipelines, which will ease process operation and control. Due to the complexity of the problem, multistep solving method based on theorem of corner points has been developed. The FWN obtained using the proposed method also includes information on the maximum flow rate in the pipelines, which is essential for detailed network design stage. The resulting model is a mixed integer linear problem (MILP), which may be solved to obtain global optimum solution. Two case studies were used to elucidate the newly proposed method.
