Dirty hands on troubled waters: Sanitation,access to water and child health in Ethiopia

In this paper, we investigate the impact of access to drinking water sources and sanitation facilities on the incidence of diarrheal diseases among children below 5 years of age in Ethiopia using the propensity score matching technique with a polychotomous treatment variable. We find that among the water sources traditionally considered as improved, only water piped into dwelling, yard or plot leads to a large percentage point reduction in diarrhea incidence. The other water sources, generally believed as clean, are not effective in reducing diarrhea even compared with some of the unimproved water sources. We also find that some unimproved water sources and sanitation facilities are less inferior than they are believed to be. These results suggest that the traditional way of categorizing different types of improved and unimproved water sources and sanitation facilities into a dichotomous variable, “improved” or “unimproved”, could be misleading as it masks the heterogeneous effects of the water sources and the sanitation facilities.

A comparison of the efficacy of chef knife-cleaning methods

Improperly cleaned and sanitized chef knives present a potential contamination risk and a source for foodborne illness. This study compared the efficacies of two cleaning methods (three-compartment manual dishwashing and sanitizer wiping) at removing food soils from contaminated chef knives. Knife-washing procedures were standardized after observing knife-cleaning behavior in a kitchen. Adenosine triphosphate bioluminescence was used to measure levels of organic soils. Results indicated that the three-compartment manual dishwashing was more effective at removing food soils from knife surfaces than the sanitizer wiping (P < .0001). This study also assessed the influence of other factors on the soil removal efficacies.

基于DEA的城市市容环境卫生效率研究

本文选取城市市容环境卫生专用车辆数和从业人员数作为投入变量,道路清扫面积.生活垃圾清运量、粪便清运量作为产出变量,采用数据包络分析方法分析了我国城市市容环境卫生效率.结果发现,我国城市纯技术效率比规模效率低.总体技术效率不高,绝大多数城市处于规模效率递减阶段,城市环境卫生效率与城市所处的地理位置关系不大.环境卫生管理体制已经不适应城市化高速进程.因此,应大力促进环境卫生领域的技术进步,改进管理体制,提高城市环境卫生行业的投入产出水平.     

玻璃钢材料在环卫机械制造中的应用

玻璃钢材料耐腐蚀强、韧性好、重量轻,适合应用在环境条件恶劣、耐腐蚀性强的环卫机械中,是环卫机械制造选材中的最佳应用材料.玻璃钢材料重量轻的特点还有助于减少设备自身重量,减少设备因自重而耗费的电瓶动能,延长工作时间,增加效率.用玻璃钢材料代替钢材、有色金属是环卫机械制造发展的必然趋势.

基于政策导向的医用耗材管理

《关于深化医药卫生体制改革的意见》和《全国医疗服务价格项目规范（试行）》两政策对医院来说,都是更大的挑战。基于这些政策导向,就必须加强医用耗材管理,规范医用耗材的使用。为此,应控制高端产品的适用范围;引进ERP系统,同时对高值耗材实行条码化管理,确保医用耗材的实耗实销。将政策导向贯彻到医用耗材管理中,实现账物相符,收支平衡,杜绝内耗,在保证医护质量的情况下,合理使用医用耗材,保证患者费用合理,控制医疗费用的不合理增长,确保医院成本效益合理。     

Urban agriculture and sanitation services in Accra,Ghana: the overlooked contribution

While urban agriculture has long been valued for providing food security and nutrition within cities, it contributes to many other urban services that are seldom cited as rationales for protecting or even expanding urban food production. Articulating the actual and possible contributions of urban agriculture to municipal sanitation and health services is critical for sustaining these urban farms and their functions into the future. In the context of the low coverage and performance of wastewater treatment plants in Accra, Ghana, health risk reduction measures implemented on and off farm can substitute to a large extent for this absence of conventional wastewater treatment. We estimate that Accra generates approximately 80,000,000L of wastewater per day, of which urban vegetable farms alone use up to 11,250,000L. By mitigating the health risks for farmers and consumers associated with widespread wastewater irrigation, these urban farms have the potential to significantly contribute to the city's sanitation needs. This could allow partial outsourcing of public health services from treatment plants to the farm, where wastewater is considered an asset instead of a problem. Urban agriculture could also significantly support buffer zone management along streams and rivers, resulting in a reduction of solid waste dumping and environmental pollution, but most importantly an improvement in flood control and related public health challenges. While urban agriculture is not the panacea for addressing these urban challenges, it can significantly contribute to their solution.
