煤矿安全质量标准化管理信息系统的开发与应用

针对我国安全质量标准化工作日常考核和汇总繁琐且不利于统计分析的问题,采用ASP.NET与SQL Server的技术,以国家煤矿安全质量标准化及考评办法为依据,融合煤矿企业安全质量标准化的现场管理考评实际,开发设计了包括政策查询、考评标准和方法查询学习、考核评级、结果查询、统计分析、后台管理在内的6大功能模块的煤矿安全质量标准化管理信息系统,并在某矿业集团进行了实际应用。在理论与实例应用的基础上,得出系统可以有效对安全质量标准化标准自查过程的记录,对隐患按项目进行归类管理,对检查结果进行统计分析,及时跟踪处理现场存在的安全隐患。     

Currarino triad: concurrent US and MRI diagnosis in the fetus and the mother

We report an unusual case of the complete Currarino triad diagnosed in a fetus at 21 weeks' gestation by means of prenatal ultrasonography (US). The highly suspicious findings in the fetus were accompanied by analogous US findings in the mother who suffered from mild symptoms of up to that time unrecognized Currarino triad. Consecutively, magnetic resonance imaging (MRI) confirmed the findings simultaneously in the fetus and in her mother. This is the first report describing the prenatal diagnosis of Currarino triad without the background of positive family history. To our knowledge, the prenatal MRI findings of Currarino triad have not yet been published. Copyright © 2002 John Wiley & Sons, Ltd.     

扩展性案例在《Web应用开发技术》课程教学中的应用

《Web应用开发技术》是一门实践性和综合性较强的课程,扩展性案例的选取对课程教学具有重要作用。以＂登录注册系统＂为例,通过不断扩展该案例的功能,把各章知识点逐步融入到扩展性案例当中,使学生对各章主要知识点的应用有一个清晰的整体认识,激发学生求知、求技、求异、求新的兴趣,实现理论与实践的统一。
