Experimental Research on Early-Age Property of High-Performance Concrete Column by Embedded Sensors

This paper aims at monitoring the autogenous shrinkage (AS) of a high-performance concrete (HPC) column specimen using an embedded strain gauge just after concrete pouring. A real size specimen (40 cm x40 cra x 100 cm ) was made to simulate the structural members in construction site. The results show that the amount of HPC AS is comparable to that of drying shrinkage and even larger than it, so AS can not be omitted for HPC. By comparing the plain I-IPC and reinforce, d HPC specimens, the influences of reinforced bars on autogenous shrinkage and temperature distribution were obtained.     

ICU临床带教中影响师生沟通的因素分析及对策

目的：探讨ICU临床带教中影响师生沟通的因素,提出针对性的应对策略。方法：针对2005年7月至2007年5月ICU实习护生275名,采用护生病床负责制一对一临床带教,并以调查问卷或定期师生座谈的形式,总结分析ICU临床带教中影响师生沟通的因素,针对性实施应对策略。结果：影响师生沟通的五个方面因素分别是工作环境、教师语言、教师心理、教师道德修养和专业技能水平、学生自身因素。结论：加强临床带教工作管理;消除工作环境带来的顾虑;师生互动,共同参与带教计划的实施;提高教师个人修养,建立良好的师生关系;结合临床,实施情景沟通法;根据护生个性特征,采取个性化的沟通和教学方案等是当前ICU临床带教工作中增进教学效果行之有效的方法。
