This study tries to suggest a program that the function of a campus can be extended to its community and to be decentralized. This sort of program should be applied to the community without any trouble and be an integration type which the campus members can use actively. To make this possible we observe the activity patterns of the campus members and try to understand the motivation of the activity choice. Finally we deduce the campus activity core. Also, based on understanding the community closed to the campus, we find out what campus can contribute as a community member, not an isolated campus. Through this, the study suggests a program that community and campus devise the growth together as a companion and finally be able to extend its main functions to the community.
