This paper confirms the risk of using smartphone through the analysis of collected usage pattern and proposes the smartphone intervention system in risk situations. In order to check the risk of smartphone usage, we made information collecting application and collected smartphone usage pattern from 11 experiment participants for two months. By analyzing smartphone usage pattern, we confirmed that about 12% of smartphone usage is being used in driving, walking, and on the street. In addition, we analyzed the response rate of smartphone notification in risk situations and confirmed that user responds the smartphone notifications in real-time even in risk situations. Therefore, it is required to present a system that intervenes the use of smartphone in order to protect smartphone users in risk situations. In this paper, we classify risk situations of using smartphone. Also, the proposed smartphone intervention system is designed to periodically detect risk situations. In risk situations, smartphone function can be restricted according to user setting of smartphone. And smartphone can be used normally when safe situation is restored.

It is widely known that the public library in Korea has not been developed as a social agency which makes communication process possible. The public library in Korea just plays a role of the public study room for students using their own books. There is almost no public libraries in the sense of an open collection of comprehensive materials designed for use by anyone who seeks information. This study starts from this situation. It aims at identifying the present stage of the development of public libraries in Korea through investigating librarians' consciousness in their everyday lives. For this, a case study method is used for investingating, collecting and organizing the 'discourse' of librarians in Pusan and Kyongsangnamdo area. Major suggestions include : First of all, it is most important for public library reformation to eradicate the 'conservatism' in the consciousness of librarians in their everyday lives. So, it is essential to collect their life stories in various library conditions, and make them public discourse of librarians. Secondly, the professional organization should play a role to unify the librarians. For this role, it should maintain a R&D department and strengthen PR programs. Thirdly, Researchers who study Library and Information Science in Korea should be always concerned with the real-life context in the field. The most important type of research in our third world situation is the one that is based on the present stage of the development of our own libraries and the real library situation in the field.

In the year 2002, 11,202 cases of electrical fires caused 462 casualties and about 58 billion won of physical damages. The electrical accidents alone caused victimized 854 people, including 87 deaths. at present, no detailed statistics about electrical fires is available. Also, there is no statistics about electric shocks and electrical equipment accidents. the electrical accidents are on the increase, proportional to the increase of electrical use. Therefore, a statistical analysis of electrical accidents is required to understand the situation and take measures to prevent similar accidents.
