인터넷 이용 경험이 적은 초보자뿐만 아니라 경험자도 인터넷에서 자신에게 필요한 정보를 찾기는 쉽지 않다. 인터넷 정보자원은 급증하는 반면 인터넷 검색엔진이 원하는 정보를 찾아주는 확률은 오히려 줄어들고 있는데 이는 체계적으로 정리되어 있지 않기 때문이다. 본 연구는 인터넷의 잔문 즉 웹브라우저를 실행한 후 처음 접속하는 사이트인 포털사이트(Portal site)를 전문화하여 궁극적으로 포털을 정보이용의 최종 목적지가 될 수 있는 모형을 설계하였다. 이 모형은 도서관이 보유하고 있는 학술정보 뿐만 아니라 인터넷의 정보자원을 체계적으로 정리하고 부가서비스를 제공하여 이용자의 정보이용 편의성을 높이는데 있다.

This study emphasizes the necessity of implementing political supports for artists and suggests several details to develop related industries. For these objectives this study analyzes the trend in related researches and overhauls the aid system. It then comes up with results about how artists are aware of the supporting system by conducting a survey of 140 artists. The result of summarize as follows. First, most of the artists have severely limited access to government-funded or private aid programs. This signals the urgency of establishing an integrated portal site since the artists aren't evenly offered the information they need. Along with this, artists should note that the main purpose of this portal site is focused on providing information related to livelihoods. Secondly, the analysis shows the lack of infrastructure for supporting artists. Both governmental and private sectors should take charge of establishing art consulting agencies which can bring efforts to improve rights and interests of many artists via a number of channels. Supporting artists also presents its necessity about solving social problems besides the one suggested by previous studies. This study has its significance by implying the actual perspectives of artists while most of the related studies are rather theoretical.
