简介:一种普通情形在象地震那样的灾难期间是地点上的损坏地侦察的活动是不协调得好的。例如在意大利,对在地震以后的结构的损坏评价从意大利的紧急情况权威被管理,用被产生在填写并且转到灾难管理起作用的中心的表格的很多混乱的地点上的专家填写的打印表格(豹脚蚊)。因为这,论文探索使用活动通讯技术(聪明的电话)和网开发将在主要灾难以后帮助社区的反应系统的生存能力,提供为允许上载并且散布信息的居民和应答者的隧道,与协调损坏域侦察的结构的损坏有关。能被居民在聪明的电话上运用的一个活动应用程序被开发了,到当时,给起始的损坏区域的评估,它将很有用资源(例如专家的数字被限制)。活动应用程序在2012Emilia地震期间第一次被测试了提高紧急情况反应,显示出在把建议过程与标准过程作比较的统计术语的建议方法的效率。

简介:人民公社体制下的农村集体财产依次归属于公社、生产大队、生产队所有,立法以及实务部门也就将生产队视为了基本核算单位,农民集体财产就主要归属于生产队所有,但随着对人民公社体制的政社分离的改革,公社、生产大队、生产队就演变为各类农村集体经济组织,原管理范围内的农民集体财产就由农村集体经济组织进行管理,同时,政社分离改革的另一后果就是农村公共事务处于无人管理的境地,立法也就允许设立村民委员会而予以应对,在借鉴城市居民委员会内设居民小组的立法经验的基础上,村民委员会就内设了村民小组。当然,乡政府、村民委员会、村民小组分别主要以原公社、原生产大队、生产队为基础而进行设立,因绝大多数的农村地区并没有设立独立的农村集体经济组织,村民委员会、村民小组就担当了管理农民集体所有财产的职能,尽管村民委员会是否存续处于不确定状态,在没有独立设立管理农民集体所有财产组织的情形下,村民委员会就应当予以继续管理农民集体所有财产,村民小组享有独立的法律地位就毋庸置疑。不过,现行立法关于村民小组的规定过于简单,有必要予以完善。
简介:摘要目的研究分析奎硫平快速加量治疗精神分裂症急性期患者的临床治疗效果及其引起的不良反应。方法将2013年4月~2014年4月一年内在我院精神科诊治为精神分裂症急性期的50名患者作为临床研究对象。将该50名患者随机分为对照组和观察组,并采用两种不用剂量的奎硫平快速加量法进行治疗。对照组患者用药第一天服用奎硫平的剂量为100mg,此后每天服用奎硫平的剂量以100mg/d递增,7d内患者服药剂量达到600mg/d。观察组患者用药第一天服用奎硫平的剂量为200mg/d,此后以200mg/d的量递增,在4d内患者用药剂量达到600mg/d。此后以600mg/ml的量连续治疗1个月。观察两组患者在用药第7d和用药1个月后的治疗效果及不良反应。结果7d后,对照组和观察组的治疗总有效率为24.0%,28.0%。不良反应发生率为32.0%,52.0%。两组的不良反应相比,有较大差异,p<0.05。1个月后,对照组和观察组的治疗总有效率为64.0%,64.0%。不良反应发生率为12.0%,16.0%,无较大差异。结论两种剂量疗效相似,但是以100mg/ml奎硫平为初始治疗剂量能够减少全程不良反应的发生。
