Disaster survivors suffer, in most cases, a great economic loss, heavy physical damages and, moreover, some dreadful mental pains. The psy- chological shock aroused by disasters especially deteriorate one's social capabilities. So, even when the disastrous state of affairs come to an end, disaster survivors tend to suffer serious conflict with their family members and mistrust in other people in their regional society. In this context, policy plans of emergency management aiming at mitigating psychological impact of di- sasters.
Among those mental impacts of a disaster, there are two sorts that are most noticeable. The com- paratively simple one among them is Acute St- ress Syndrome occurring as an instant response to the unexpected situation of disaster. But the more complex and long-term enduring trouble in Post Traumatic Stress Disorder causing still more serious psychological problems. A nation-wide public support system should be established for disaster survivors to return to their social life as a wholesome members, preventing them from fall- ing into PTSD victims.
Supporting those catastrophe sufferers should not stop at the level of economic assistance or material restoration, but need to progress to measures for recovering socio-cultural health of them. For a successful establishment of these supporting institutions, policy planners as well as pertaining researchers should develop a wide and deep understanding of the behavioral res- ponse of those sufferers as an effect of disaster experience.
Emergency management and control are such tasks as to be accomplished through a common effort of regional communities and the national government, together with that of social activists. In addition, some extraordinary social concern and policy consideration should be given to the social minorities who are apt to be frequently exposed to social and natural dangers and so who are weak in elasticity of treating disaster impact.
