[Building information infrastructure at research institutions that support health hazard control]

In recent years the Ministry of Health and Welfare (MHW) encountered large scale health hazards and medicare incidents that required flexible, intersectional, and dynamic responses. Both research institutions under the MHW and their researchers got involved in project teams which were organized in order to cope these hazards and incidents. However it might be more effective if some information infrastructure for hazard control is built as one component of the MHW hazard management system. In this paper the design concept and implementation for such information infrastructure were discussed. The infrastructure consists of computer networks and systems which are based on the Internet and the related technologies such as WWW.
