For a sustainable service, cloud computing services must control user access. The essential business characteristics of cloud computing are payment status and service level agreement. This work proposes a novel access control method for personal cloud service business. The proposed method sets metadata, policy analysis rules, and access denying rules. Metadata define the structure of access control policies and user requirements for cloud services. The policy analysis rules are used to compare conflicts and redundancies between access control policies. The access denying rules apply policies for inhibiting inappropriate access. The ontology is a theoretical foundation of this method. In this work, ontologies for payment status, access permission, service level, and the cloud provide semantic information needed to execute rules. A scenario of personal data backup cloud service is also provided in this work. This work potentially provides cloud service providers with a convenient method of controlling user access according to changeable business and marketing strategies.展开更多
目的以福建省某三甲综合医院眼科白内障手术患者为例,对比扩大疾病诊断相关分组(diagnosis related groups,DRG)改革前后患者白内障手术住院费用的变化,探讨基于DRG在临床科室精细化管理中的应用路径,为推进医保支付制度改革提供依据。...目的以福建省某三甲综合医院眼科白内障手术患者为例,对比扩大疾病诊断相关分组(diagnosis related groups,DRG)改革前后患者白内障手术住院费用的变化,探讨基于DRG在临床科室精细化管理中的应用路径,为推进医保支付制度改革提供依据。方法收集2021年1月—2022年1月福建省某三甲医院眼科患者出院记录,对DRG收付费实施前分组的组间比较采用Mann-Whitney U检验评价,对影响DRG收付费用的因素采用单因素分析后纳入多元线性回归模型,结果均以P<0.05为差异有统计学意义。结果对比DRG医保支付费实施前后病例,发现住院天数、按项目结算费用、两种结算方式差额、药品费、检查化验费、耗材费、手术费、医务性收入、麻醉科总费用差异有统计学意义(P<0.05)。根据标准化系数可见,耗材费、医务性收入是影响DRG支付金额主要因素。结论进一步完善DRG收付费管理工作,医院内部制定合理临床路径与成本管理体系,实现医院精细化管理。展开更多
