    临床路径是医院重要工作的一部分。国家卫生行政部门已经于2009年正式 提出该项工作,主要是完成某一单病种的诊断、治疗、康复和护理所制定的一个 诊疗标准化模式。临床路径实施初期阶段,医院使用手工方法进行管理,无法固 定单个病种治疗过程,且经常调整治疗方案,根本无法达到卫生行政部门的要求, 与实行临床路径的初衷相违背。为了规范临床路径管理工作,构建一套临床路径 信息管理系统显得尤为迫切和重要。 本文讨论了临床路径信息系统的概念与背景,分析了临床路径的业务流程, 并简述了该系统与其它业务系统的关联。需求分析完成后,又完成了该系统的架 构、功能要求及Caché数据库的设计工作。根据需求...Clinical pathway is an important part of the hospital daily routine. The State Health Department has formally proposed this work in 2009,with focus on establishment of a standardized model on clinical diagnosis, treatment, rehabilitation and care. During the early stage of the implementation, manual methods are applied, which cause big variation of the treatment of a single disease. Moreover, ...学位:工程硕士院系专业:软件学院_工程硕士(软件工程)学号:X201323012

    Information Asymmetry、Institutional Constraints and Investment Capital Allocation Efficiency:Evidence From Different Property Rights Arrangements

    在完美的资本市场上,投资机会是投资政策的惟一驱动因素(Hayashi,1982[4]),然而,现实中的投资却受到投资机会之外的诸多因素的影响(如Fazzari等,1988[5])。在作为市场微观主体的企业层面上,投资与内部现金流之间的相关关系广泛存在,是投资资本配置缺乏效率的突出特征之一。近年来,学者们将“投资-现金流”敏感度区分为“投资过度-内部现金流富余”相关性与“投资不足-内部现金流紧缺”相关性,以便识别道德风险与逆向选择这两种形式的信息不对称对投资资本配置效率的影响(Richardson,2006[6])。本文在此基础上,进一步引入制度约束,区分国有和非国有两种不同的产权安排,分析投资...In the perfect market, investment opportunity is the only reason for the investment decision. However, there are many factors affect corporate investment actuality. As the microcosmic of the market, corporate invest level relate with the interior cash flow prevalently, which is one of characteristics of invested capital ineffective allocation. In recent years, academicians depart the sensitivity o...学位:管理学硕士院系专业:管理学院财务学系_财务学学号:1762008115140

    本文区分两种不同性质的投资-现金流相关性,从信息不对称和制度约束两个角度,对我国不同产权安排下的资本投资效率进行分析和检验。研究发现,地方国有企业更有可能出现“现金流富余-投资过度“相关性,缓解道德风险的公司治理和减少政府干预的政府治理有利于改善其投资效率;非国有企业更有可能出现“现金流不足-投资不足“相关性,为解决逆向选择而增强信息透明度和为克服制度性金融歧视而改善融资条件有助于提高其投资效率。From the perspectives of information asymmetry and institutional constraints, this paper distinguishes two different kinds of investment-cash flow correlation and analyzes and tests the investment efficiency under different property rights arrangements in China.Evidences suggest the following results: Companies controlled by local government are more inclined to have"free cash flow-overinvestment correlation".Both corporate governance which mitigates moral risk and government governance which mitigates government intervention help these companies to improve investment efficiency.Companies controlled by private persons are more likely to have"insufficient cash flow-underinvestment correlation".Both information transparency which alleviates adverse selection and financial constrains releasing which alleviates institutional financial discrimination help these companies to improve investment efficiency.国家自然科学基金(71102060、71002042); 教育部人文社科项目(09YJC630140); 教育部博士点基金(20120121120008)的资

    Exechon机床的并联模块为3自由度2UPR-SPR机构,是一种两转动一移动并联主轴头。将动平台输出轴设置为偏置形式,可提高姿态能力。采用0扭转角的倾摆—扭转角描述动平台姿态,建立机构位置反解数学模型。在此基础上,以局部传递指标(Local Transmission Index,LTI)为运动/力传递性能评价标准,分析机构优质传递姿态工作空间(Good Transmission Orientational Workspace,GTOW)和优质传递姿态能力(Good Transmission Orientational Capability,GTOC)。给出姿态能力分析实例,并绘制机构LTI,GTOW分布图和优质传递空间曲面。对比分析结果表明,偏置输出轴的GTOC优于正置情形,最佳偏置角对应的GTOC可达46°

    对于含砷较高的金矿,在研究和生产实践中多采用二段焙烧技术进行预处理,通过除砷和除硫来获得较高的金浸出率。如何通过采用更低成本的预处理方法来进一步降低尾渣的含金量,是目前研究和生产实际中亟待解决的技术难题之一。在对某二段焙砂进行化学分析、矿物组成及金赋存状态分析的基础上,进行了强酸浸出提高金氰化浸出率的试验研究,着重探讨了磨矿粒度、浓硫酸用量、浸出温度和浸出时间对金氰化浸出率的影响。试验结果表明:在二段焙砂球磨1 h,每吨二段焙砂的浓硫酸用量为2 t,酸浸反应温度为95℃以及浸出时间为2.5 h的条件下,金的氰化浸出率可达97.86%
