Abstract
In recent years, many medical incidents and accidents in hospitals are being reported and to introduce a policy which prevents these accidents is an urgent issue. In this article, we propose a modeling method which utilizes the caring data of nurses monitored by ubiquitous sensors. Our model is based on an analysis of voice records, video records, place data detected by infrared ray sensors, and motion data detected by acceleration sensors. We introduce a hierarchical nursing workflow model to describe a prepared nursing manual and implement a workflow detecting system. By this system, we can interpret and understand the monitored data as actual caring motion of nurses.
