The purpose of this study is to develop the computerized health instruction system to manage the Health Management Members(HMM) of the Gangbook-ku Health center in Seoul who have registered for the life-time health promotion. The HMM have been checked up and classified into 3 groups - healthy, borderline and ill group - based on their health assessment data through the computerized management system. But the computerized supporting programs for intensive management have not been sufficient enough to offer clear health instructions to the HMM and more than one user in the health center have not been able to use the system at the same time. Therefore, we have developed some new health instruction programs and upgraded the system to be used concurrently. For that purposes, we have used Delphi, Microsoft Access, ActiveX Data Objects(ADO) technology as development tools. We expect thi system to be used for health management of other public health centers, schools, and occupational settings, furthermore for evaluation of health promotion services. Additionally, this new computerized health management system supplemented with health instruction programs should be integrated to the computerized health care system at health centers in near future.
