In Macao, scarce water resources deteriorate rapidly in emergency situations, such as accidental chemical spills upstream of the supply reservoir or salty tides. During these times, only the water from the two freshwater reservoirs in Macao can be used. In this study, we developed urban water management optimization models that integrated the raw water supply from the two reservoirs with various proposed governmental policies (wastewater reuse, rainwater collection, and water saving). We then determined how various water resource strategies would influence the urban water supply in Macao in emergency situations. Our results showed that, without imported raw water, the water supply from only the two Macao reservoirs would last for 7.95 days. However, when all the government policies were included in the model, the supply could be extended to 13.79 days. Out of the three non-conventional water resources, wastewater reuse is the most beneficial for increasing the Macao water supply, and rainwater collection also has great potential.展开更多

Most of the trauma patients were sent to prima hospitals to receive treatments. But the traditional mode of separate discipline management can easi lead to delayed treatment, missed or wrong diagnosis and high disability, which causes a high mc tality in severe trauma patients. Therefore, if the primary hospitals, especially county-level hospit~ (usually the top general hospital within the administrative region of a county), can establish a sc entific and comprehensive trauma care system, the success rate of trauma rescue in this region can ] greatly improved. On March 1st, 2013, Tiantai People's Hospital of Zhejiang Province, China set up trauma care center, which integrated the pre-hospital and in-hospital trauma treatment procedur~ and has achieved good economic and social benefits. Till March 1st, 2017, 1265 severe trauma patier (injury severity score 〉16) have been treated in this trauma center. The rescue success rate reach~ 95~ and the delayed and]or missed diagnosis rate was less than 5%. Totally 86 severe cases of peK fractures with unstable hemodynamics were treated, and the success rate was 92%. The in-hospil emergency rescue response time is less than 3 min, and the time from definite diagnosis to surge is within 35 min.展开更多
