The emerging network-enabled medical devices impose new challenges for the safety assurance of medical cyber-physical systems (MCPS). In this paper, we present a case study of building a high-level safety argument for a patient-controlled analgesia (PCA) closed-loop system, with the purpose of exploring potential methodologies for assuring the safety of MCPS. 1998 ACM Subject Classification D.2...

Refactoring to patterns allows software designers to safely move their designs towards specific design patterns by applying multiple low-level refactorings. There are many different refactoring to pattern techniques, each with a particular purpose and a varying effect on software quality attributes. Thus far, software designers do not have a clear means to choose refactoring to pattern techniqu...

The field of data quality management has long recognized the negative impact of data quality defects on decision quality. In many decision scenarios, this negative impact can be largely attributed to the mediating role played by decision-support models with defected data, the estimation of such a model becomes less reliable and, as a result, the likelihood of flawed decisions increases. Drawing...

Data and information quality is a well-established research topic and gradually appears on the decision-makers' top concern lists. Many studies have been conducted on how to investigate the generic data/information quality issues and factors by providing a high-level abstract framework or model. Based on these previous studies, the researchers of this paper tried to discuss the actual data qual...

BACKGROUND In economic evaluations of care services for older adults health-related quality of life (QoL) measures such as the EQ-5D are increasingly replaced by the ICECAP-O and ASCOT, which cover a broader scope of QoL than health alone. Little is known about the content validity and feasibility of these measures. The purpose of this study was to explore the content validity and feasibility o...

Software Quality Assurance (QA) is a key area in the development and maintenance of scientific software systems in order to ensure the reliability of the output generated by such systems. Approaches taken in implementing QA within the lifecycle include manual techniques, which require developer intervention, and automated techniques, which can be completed by analysis toolsets. Manual QA techni...
