Automatic software install/update for embedded Linux

Linux has a special feature of automount in the Linux kernel. Filesystem can be mounted and unmounted automatically. Its performance is similar to MS Windows. It works well under demands of more saving resources and automatization, like memory of system. An approach to install/update software automatically on embedded platform was proposed. This approach derives from above feature based on embedded environment with Linux OS. Configurations of files related to this feature were introduced. An example in practice was given to realize this approach from universal serial bus （USB） memory disk when USB disk is available.     

SOAP分诊法在成人急性胸痛预检分诊中的应用

目的:探讨SOAP分诊法在成人急性胸痛预检分诊中的应用效果。方法:选取2012年7~9月收治的急诊急性胸痛病例89例为对照组,凭经验进行分诊;选取2012年10~12月收治的急诊急性胸痛病例96例为实验组,按照SOAP分诊法对成人急性胸痛患者进行分诊。结果:实验组护士的分诊准确率、预见护理率、患者满意度明显高于对照组(P<0.05)。结论:SOAP分诊法提高了成人急性胸痛患者的分诊准确率,实行预见性急救护理,使分诊趋于科学化、规范化,提高患者满意度。     

Online Mind-Map as Interface of Electronic Resource Integration and Sharing

The paper aims to research on online mind map as interface of learning resource integration and sharing.We developed a web application that provides a interface to allow users to create a knowledge mind map.With the online mind mapping tool,the electronic learning resource will be discovered and shared in the form of subject-oriented package,it is more flexibly than the other E-Learning systems,and the interaction and cooperation of the users are strengthened to some extent.     

嵌入式船舶运行数据库中信息快速查询方法

针对当前嵌入式船舶运行信息数据库信息查询的开销大,查准率不好的问题,提出基于模糊聚类和相关谱特征提取的嵌入式船舶运行数据库中信息快速查询方法。首先进行嵌入式船舶运行信息资源数据的采集和存储结构分析,提取嵌入式船舶运行信息数据信息流特征,对船舶运行数据进行自相关特征分析,提取反映船舶运行状态特征的相关谱特征量,对提取的谱特征量采用模糊C均值聚类方法进行特征识别和分类处理,提高数据库查询的目标指向性,实现数据库信息快速查询。仿真结果表明,采用该方法进行嵌入式船舶运行数据库中信息查询的查准率较高,实时性较好。
