Based on the Fact Sheet: Journal Selection for Index Medicus/MEDLINE and the Fact Sheet: Response to Inquiries about Journal Selection for Indexing at NLM, this article was to introduce the MEDLINE database, the process of applying a journal to be indexed in the MEDLINE database and review process. Meanwhile, this paper was to share Tzu Chi Nursing journal Editor's experiences in applying the Tzu Chi Nursing Journal to be indexed in the MEDLINE database, and hopefully these experiences can provide other nursing publishers with a reference.

本文参考「MEDLINE期刊筛选条件之说明」与「申请加入国家医学图书馆资料库之说明」此两份文件，兹对MEDLINE资料库、申请加入MEDLINE资料库之过程以及审查过程做一简明介绍，同时也分享慈济护理杂志总编辑向「美国国家医学图书馆」提出申请「慈济护理杂志」加入MEDLINE资料库之经验谈，期望此经验可做为其它护理杂志社的参考。

In the design and implementation of the database applications part,this paper introduces a method of progressive expansion to design concept structure of the database, and put forward the "pseudo-code" to solve the existing problem in modification complexity and large data redundancy after using the traditional method of normalization theorem to process the database.

在该系统数据库设计与实现部分，本文介绍了运用逐步扩张的方法设计本数据库概念结构过程，并提出了"伪码"的概念以解决利用传统规范化理论处理后数据库存在的修改复杂、数据冗余度大的问题。

Now keyword search over relational database is becoming a hot research topic in both database and IR area. There are two kinds of popular keyword search systems, while neither of them can give accurate results with high speed. The on-line system can obtain the latest search results while the search speed is low; The off-line system speeds the query processing by means of preprocessing, but the disadvantage lies in expensive cost needed to preprocess again once the database is updated.

关系数据库上的关键词检索已成为数据库和信息检索领域的研究热点之一现有数据库关键词检索系统可分为在线和离线两大类，它们都难以兼顾查询效率和效果：在线系统能够获得数据库最新结果，但速度较慢；离线系统使用预处理提高查询速度，但若数据库更新就要重新执行预处理。

The first method defines sample database by artificial operation, the second method builds one sample database and one potential sample database by the sample\'s self- training method. Some potential geometric regions are obtained by using a simple fast Hough arithmetic.

同样通过简单的快速Hough算法获取一些潜在几何区域，用对二值图像的块匹配方法对潜在的矩形区域进行识别并把它分类变成几种比分板和广告块。

So can visit the database directly , no longer need involvement of WEB database ; The control of users visiting can be solved quick-wittedly, improve the security ; Meanwhile , the JDBC database can realize being mutual with users conveniently , offer abundant figure function and sound, such information functions of the multimedia as the video ,etc..

所以可以直接访问数据库，不再需要WEB数据库的介入；用户访问控制可以由数据库服务器本地的安全机制来解决，提高安全性；同时，可以方便地实现与用户交互，提供丰富的图形功能和声音，视频等多媒体信息功能。

Currently, research of parallel databases mainly focuses on relational database, and parallel environments are always based on special parallel architectures. With the rapid expanding of the markets of object-relational database, requests to parallel processing are increasing screamingly Certainly it will be significant to build a parallel objectrelational database. But it is a challenging work too.

本文分析了我国电力系统运行特点及其对短期调度与运行优化提出的要求，针对调度中心能量管理系统的重要组成部分——短期调度与运行优化，应用数学规划的理论和方法，解决复杂水火系统短期经济调度中的水火电计划与调度和电网络运行优化问题。

As the development environment, SQL SERVER 2000 is regarded as the database server , static news of the classification of the news, template, front desk of page self-defining to turn into, and authority and backup person who shrink a series of functions of database , administrator of backstage supporter ,, have finished all functions of a static news briefing system, realize the course has adopted a large amount of JAVABEANs to realize the complicated logic operation to the database and server..

摘要本系统采用JDK 1.4.1作为开发环境，SQL SERVER 2000作为数据库服务器，实现了对新闻类别无限级分类设置，静态新闻的发布修改删除，前台页面的模板自定义和生成，以及后台管理员权限和数据库的备份收缩等一系列的功能，完成了一个静态新闻发布系统的所有功能，实现过程了采用了大量的JAVABEAN来封装对数据库和服务器实现复杂逻辑操作。

The traditional query tree optimization methods,parallel database optimization methods based on left linear trees and right linear trees,bushy trees,and operation of the forest,have their own pros and cons,they have been more in-depth and maturity of the study.The query optimization method based on multiple weighted tree has studied its model of parallel query plan,its complexity model of parallel query plan and query optimization algorithms.The semantic query method transforms an inquiry into one or several semantic equivalence inquiries then has to find and implement a strategy to achieve a better query.Agent-based parallel database query optimization using Multi-Agent technology to automatically search the integrity constraint conditions which are related to the determined query,there for,the efficiency between several relations' joins has been greatly improved.The parallel optimization algorithm,based on genetic algorithm which is suitable for multi-joins of cluster environment,has deeply studied the relations storage options,multi-joins query optimization and query processing and other key technologies based on cluster parallel database.

传统的查询树优化方法，即基于左线性树、右线性树、浓密树、操作森林的并行数据库查询优化方法，各有优劣，对其的研究比较深入、成熟；基于多重加权树的查询优化方法，研究了其并行查询计划模型、并行查询计划的复杂性模型和查询优化算法；语义查询优化方法将一个查询变换成一个或数个语义等价的查询，进而寻找并执行这些等价查询中具有较好实现策略的一个；基于Agent的并行数据库查询优化采用Multi-Agent技术自动查找与给定查询有关的完整性约束条件，使得多个关系间连接操作的效率得到很大的提高；基于遗传算法的并行优化算法，深入研究了基于机群并行数据库中关系存储的选择、多连接查询优化和查询处理等关键技术。
