精神科护理安全管理中应用的品管圈活动

目的研究精神科护理安全管理中应用的品管圈活动作用。方法选取我院2010年1月-2013年12月间诊治的精神科患者800例,将其随机分为观察组和对照组各400例,对观察组患者在护理安全管理中应用品管圈活动,对对照组患者进行常规护理,对比观察两组患者的临床护理效果。结果在医患沟通率、常规操作合格率、护理人员对患者病情的掌握率及护理不良事件发生率方面,观察组明显优于对照组,差异具有统计学意义（P〈0.05）。结论在精神科护理安全管理中应用品管圈活动不仅可以提高医患沟通率、护理人员的操作合格率及对患者病情掌握率,而且还能降低不良事件的发生率,值得临床推广使用。

FEM analysis of workpiece curvature influence on groove deformation during plough process

To investigate the workpiece curvature influence on groove deformation,numerical studies with curvature varying from negative to positive were conducted on copper material.Groove deformations were analyzed,including groove geometry,effective stress distribution and plough force.The curled groove shape whose workpiece curvature was 0.133 mm-1 was validated by experiments.Moreover,a series of geometry models with various curvatures were introduced to analyze the change of groove deformation.The results show that positive curvatures influence groove deformation more intensively than negative or zero curvature.It is mainly due to the action of the tool forming face during plough process.

关于方言沟通度和方音理解的几个问题

一从方言沟通度与语感说起方言的计算研究近年来受到学术界重视,《中国语文》发表的多篇文章代表了这方面的研究成果(郑锦全1988、马希文1989、王士元和沈钟伟1992、郑锦全1994、陈海伦1996)。
