[G01-P02] A Quantitative Analysis of Nationwide Municipalities' Disaster Prevention Portals
キーワード：防災、防災教育、数量化Ⅲ類
Japan is a country of frequent natural disasters, with casualties tallied every year. Disaster prevention information and education are therefore very important to mitigate the human and material damages resulting from natural disasters.
One of the familiar disaster educational materials for people is the disaster prevention portal site in the prefecture where they reside. All prefectures in Japan have their own disaster prevention portal sites, which contains various information and educational contents pertaining to natural disaster prevention.
In this study, the disaster prevention portal sites from forty six prefectures were investigated. The results suggest that there is disparity concerning variety contents and structure, which makes it difficult to analyze comparatively or statistically. The twenty eight categories were therefore defined for the information and/or the functions that each portal contains. The value 0 or 1 were then applied to indicate the absence or presence of them. Using these numerical values, correlation analyses were conducted to evaluate the strength of the relationship between the variety among categories and some values or indexes associated with a natural disaster. Additionally, Quantification Method III was also used for multi-dimensional scaling to quantify the characteristics of the portal sites.
The variety of disaster prevention information and education seems to have almost no-correlation with both the index of susceptibility for disasters and the number of victims from disasters over the past five years. The characteristics of the portals possibly are indicated by two components involved in the information it containes, these being the degree of emergency and of concreteness for evacuation actions.
