关键词： Stroke   Rehabilitation   Outcome   Database   Korea  

摘要： The purpose of this report was to provide information for patients receiving inpatient rehabilitation after stroke and to identify the possible factors influencing functional outcome after inpatient rehabilitation. Stroke patients (n = 5,212) who were discharged from the Departments of Rehabilitation Medicine (RM) of university hospitals and rehabilitation hospitals from 2007 through 2011 were participants. Prevalence, age, transfer time after onset, length of stay (LOS), functional status at admission and discharge were analyzed. In all stroke subjects, cerebral infarctions (67%) were more common than hemorrhages. Cerebral infarctions in the middle cerebral artery territory were most common, while the basal ganglia and cerebral cortex were the most common areas for hemorrhagic stroke. The LOS decreased from 45 to 28 days. Transfer time after onset decreased from 44 to 30 days. Shorter transfer time after onset was correlated with better discharge functional status and shorter LOS. Initial functional status was correlated with discharge functional status. In ischemic stroke subtypes, cerebellar and brainstem strokes predicted better outcomes, while strokes with more than one territory predicted poorer outcomes with more disabilities. In hemorrhagic stroke subtypes, initial and discharge functional status was the lowest for cortical hemorrhages and highest for brainstem hemorrhages. This report shows that LOS and transfer time after onset has been decreased over time and initial functional status and shorter transfer after onset are predictors of better functional outcome at discharge.

摘要： The development of information systems is a difficult process that often ends in failing to meet the project's initial goals. Typical outcomes for information systems development projects include delivering promised products & services on time and within budget. These pressures are now compounded by the use of virtual teams that present a new set of challenges related to the cohesion, organization, and functioning of the team process. Specifically, virtual teams must contend with problems in team formation, the organizational environment in which the team operates, and the technology used for collaboration and communication. As more organizations use virtual teams, these problems present real and pressing obstacles to the successful completion of database systems development. The goal of the study was to determine whether leadership type, transformational, transactional, or management-by-exception was significantly related to leadership effectiveness in a virtual team tasked with developing a database management system. This study targeted millennial students at the Maine Business School who were assigned to virtual teams tasked with developing a database management system. Specifically, this study sought to answer three hypotheses: 1) what is the effect of leadership type, as self-reported through the Multifactor Leadership Questionnaire on the quality of completed team projects?;2) What is the impact of type of leadership on virtual team effectiveness as measured by the Virtual Teams Survey?;and, 3) Are there interactions between leadership style and virtual team effectiveness on the quality and uniqueness of the completed team project? Findings suggest leadership style and virtual team effectiveness did predict project quality, Transformational and Management-by-exception leadership styles had a negative relationship with virtual team effectiveness. Findings further suggest that Transactional leadership style influenced project quality directly, while transformat

关键词： 密文索引   数据库系统   算法   效率  

摘要： 密文索引方法最基本的思想是将数据库中的字符数据映射并调整为索引值,并将SQL语句转换为可以作用于索引属性列的形式。这种方法可以提高空管数据库系统中对加密字符数据内容的检索效率,并确保空管数据库系统的安全性。提出一种索引生成算法,并应用空管数据库系统的一个案例分析实现这种方法。最后完成两个实验,实验一设计了冲突检测算法,通过分析冲突概率,可以得出应用密文索引方法进行SQL查询时的效率提高方式;实验二验证了密文索引方法对SQL查询效率的提升效果。

摘要： 远程青光眼筛查时,通常是联网的基层医院或诊所对患者进行每眼单张45＆#176;数码眼底照相后,将眼底图片通过互联网上传到云数据库系统,阅片中心的医生通过阅片软件系统进行远程阅片,再将阅片报告反馈到联网的基层医院或诊所,患者通过登录互联网系统甚至移动终端（如智能手机或平板电脑等）也可查看阅片报告.单张数码眼底照相的质量标准见参考文献.
