运用护理程序开展生命网工程

生命网（Heart Care Network冠心病二级预防网）在美国，瑞典及欧亚地区20多个国家广泛开展，主要是通过对冠心病患者的危险因素评估，达到对于冠心病和高危患者按方案进行全面危险因素的纠正，使病人积极参与，有效的评估治疗率、达标率。目的是降低与冠心病相关的发病率／死亡率、防止冠心病事件的发生和复发，提高延和药物干预的临床益处。因此，受到国内专家的高度重视。1999年4月至今，我科运用护理程序，开展生命网工程，采用护理评估，制定宣教计划，开展健康教育，评价教育结果。为冠心病患者提供系统的健康指导及疾病监测。受到病人及家属广泛欢迎积极参与。

Algorithms for seismic topology optimization of water distribution network

As an essential lifeline engineering system,water distribution network should provide enough water to maintain people's life after earthquake in addition to working under daily operation.However,the design of water distribution network usually ignores the influence of earthquake,resulting in water stoppage in large area during many recent strong earthquakes.This study introduced a seismic design approach of water distribution network,i.e.,topology optimization design.With network topology as the optimization goal and seismic reliability as the constraint,a topology optimization model for designing water distribution network under earthquake is established.Meanwhile,two element investment importance indexes,a pipeline investment importance index and a diameter investment importance index,are introduced to evaluate the importance of pipelines in water distribution network.Then,four combinational optimization algorithms,a genetic algorithm,a simulated annealing genetic algorithm,an ant colony algorithm and a particle swarm algorithm,are introduced to solve this optimization model.Moreover,these optimization algorithms are used to optimize a network with 19 nodes and 27 pipelines.The optimization results of these algorithms are compared with each other.
