Identifying reusable and autonomous components is one of the most important and difficult tasks in developing component-based systems. However, the existing component development methodologies do not provide a clear standard for component identification and depend on the intuition and experience of individual developers. As a result, people with limited(More)
Malnutrition is one of the most important factors for the development of nosocomial infection (NI). We performed a study of the correlation between abnormal nutritional factors and NI risk by investigating the patients who stayed longer than 3 days in the intensive care unit (ICU) of our university hospital. The patients were classified into three groups(More)
Component-Based Development (CBD) is an emerging discipline for promoting practical reuse of software. In CBD, by building new software with independently developed components, we can gain the benefits promised by the software reuse such as quality improvement and rapid development. Accordingly, to improve quality of components, we propose the(More)
Recently, dynamic behaviors in embedded system for ubiquitous environment and service-oriented system have needed a dynamic coupling metric to evaluate the quality of the software system more accurately. The embedded systems are designed by a component-based system and the component-based system is designed by one object-oriented. Therefore, coupling(More)
Embedded systems that mutually interact with physical space have properties such as time constraint, concurrency constraint, and the control of data/resource flow. The exceptional behaviors of the system that interact with physical space can result in critical damage and cause danger to the operation of an embedded system. Thus, in order to classify and(More)
In ubiquitous environments, the content adaptable services can be dynamically provided to adapt the frequent changes of contexts. These services have common things that the kinds of context factors are limited to ubiquitous environment, though the contexts are flexible. To reuse service architecture can be reasonable for effective adaptable service. In this(More)
