Current military command information system uses electronic equipment a lot on which semiconductor chip is attached. It seems its' importance will increase more with latest information communication technology developing. Electronic equipment which uses electricity contains regular tolerance to high output electric signal. And EMC specification is the standardized of this electronic equipment's tolerance. On the other hand, the Institute of Atomic Energy Research has ever declared that high output electromagnetic pulse(EMP) will be broken out within the radius of 170Km when 10kt nuclear explosion occurs at an altitude of 40Km above Seoul. Then, the region suffer from the damage of most electronic equipments. Therefore, the norm to protect the influences in that case is defined by EMP protection specification. Most common electronic equipments meet the EMC norm, but there is no way to check whether they meet the EMP norm or not. That is because it is difficult to check whether they meet EMP protection norm and is on the matter of cost. Except inevitable cases, there is no review of checking whether they meet the norm or not. Considering the above, in this research, we speculate about the measures to improve military EMP protection ability by analyzing the EMC-EMP correlation and checking the EMP protection ability of general electronic equipment through the analysis.

Recently, natural disasters happened to the Korea frequently. Disaster in the present society has been changed and increased it impacts and extent of danger as the society develops. So, Korean people feel uneasy about the unpredictable disaster. Therefore the capability of administration system, and cooperation and support between related organization become more necessary. This study aims to find out better ways of disaster management system which can protect people's lives and fortune from all sort of national disasters. To research policy reform, it is necessary to analyze disaster response organization(national disaster prevention countermeasures headquarters and so on), interorganizational relationship, law system etc. Especially, in this study, role appreciation of government was analyzed to get the rational policy reform measure. Suggestion : First, it is necessary Establishing a consolidated organization for disaster managing and united response organization is necessary such as Federal Emergency Management Agency(FEMA) which controls an over all aspects of disaster management. And it is necessary to develop Integrated Administrative Control System based on comprehensive plan. When the accidents happen, it needs to be many equipments and various specialized personnel. So, to manage a large scale of disaster, it is necessary to have interorganizational network system which many specialized organization including volunteer group are integrated. Also, as soon as the natural disaster happen, many professionals and volunteers are distributed to the spots of disaster in the right man in the right place. Finally, All the citizens have to keep safety rules, and also to take a safe action in ordinary daily life.
