Virologica Sinica 2020年第3期35卷 290-304页

作者： Ashutosh singh Rahul Soloman singh Phulen Sarma Gitika Batra Rupa Joshi hardeep Kaur Amit Raj Sharma Ajay Prakash Bikash Medhi Department of Pharmacology Postgraduate Institute of Medical Education and ResearchChandigarh 160012India

The recent outbreak of coronavirus disease(COVID-19) caused by the novel severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) has already affected a large population of the world. SARS-CoV-2 belongs to the same family of severe acute respiratory syndrome coronavirus(SARS-CoV) and Middle East respiratory syndrome coronavirus(MERSCoV). COVID-19 has a complex pathology involving severe acute respiratory infection, hyper-immune response, and coagulopathy. At present, there is no therapeutic drug or vaccine approved for the disease. There is an urgent need for an ideal animal model that can reflect clinical symptoms and underlying etiopathogenesis similar to COVID-19 patients which can be further used for evaluation of underlying mechanisms, potential vaccines, and therapeutic strategies. The current review provides a paramount insight into the available animal models of SARS-CoV-2, SARS-CoV, and MERS-CoV for the management of the diseases.

Exploring Design Level Class Cohesion Metrics

引用

Journal of Software Engineering and Applications 2010年第4期3卷 384-390页

作者： Kuljit Kaur hardeep.singh Department of Computer Science and Engineering Guru Nanak Dev University Amritsar India.

In object oriented paradigm, cohesion of a class refers to the degree to which members of the class are interrelated. Metrics have been defined to measure cohesiveness of a class both at design and source code levels. In comparison to source code level class cohesion metrics, only a few design level class cohesion metrics have been proposed. Design level class cohesion metrics are based on the assumption that if all the methods of a class have access to similar para-meter types then they all process closely related information. A class with a large number of parameter types common in its methods is more cohesive than a class with less number of parameter types common in its methods. In this paper, we review the design level class cohesion metrics with a special focus on metrics which use similarity of parameter types of methods of a class as the basis of its cohesiveness. Basically three metrics fall in this category: Cohesion among Methods of a Class (CAMC), Normalized Hamming Distance (NHD), and Scaled NHD (SNHD). Keeping in mind the anomalies in the definitions of the existing metrics, a variant of the existing metrics is introduced. It is named NHD Modified (NHDM). An automated metric collection tool is used to collect the metric data from an open source software program. The metric data is then subjected to statistical analysis.

优质的诊断是衡量高水平医疗的重要指标。然而,诊断错误(diagnostic errors)仍是全世界共同的医疗问题,损害着全球患者的健康1-2。诊断错误的定义为:未能准确且及时地做出诊断,或未能将这些疾病信息充分、有效地与患者沟通。英国最近的一项研究显示,4.3%的基层诊疗过程中会出现诊断错误3。而另一项meta分析显示,在美国每年有近25万起诊断错误事件对住院的成人患者造成了伤害4。美国国家科学、工程与医学研究院在报告《改进医疗保健中的诊断质量》中强调,大多数人一生中会至少经历一次诊断错误1。世界卫生组织也已将减少诊断错误作为提高全球患者安全的优先事项5。
