The contemporary states are experiencing the new challenges for the crisis management. There have been many ways of researches and studies on 'how to win in the war' in the national security affairs community, but the studies on 'how to deal with crises and take measures' have been underdeveloped. The 21st century states have introduced the new comprehensive security concepts covering not only the military field but also non-military field. In order to meet the new trends, the crisis management should be developed beyond the conventional security crises, dealing with terrorism, weapons of mass destruction, drugs and transnational crimes, disasters. Therefore the all-embracing crisis management system with management, integration, and coordination functions should be introduced for the various kinds of crises. The thesis covered the conventional crisis management and crisis management theory in the prospective of sociology, and proposed the crisis management study reorientation.
