  • 본 논문은 C대학도서관의 학술정보시스템(LAS)에 구축되어 있는 장서와 대출기록 및 고객관련 데이터를 수집하여 이를 분석하고 그 결과를 고객관계관리(CRM)에 적용할 수 있는 방안을 제시하였다. 수집된 자료는 C대학도서관에서 소장하고 있는 대출이 가능한 단행본 총 269,387책의 서지데이타와 고객 12,281명의 데이터, 이용자 대출기록 39,269건이었다. 대출기록 분석 데이터에서 관계변수로 이용자 신분, 대출빈도, 대출책수와 대출횟수, 출판년도를 추출하여 데이터 마이닝 기법으로 분석하고, 상관계수로 검증하였다.

  • The aim of this study is to seek application plans of National Ecosystem Survey database based on comparison and examination of feasible analysis methods for distribution characteristics of alien plants. In order to set up a correlation analysis method between alien plants and environmental factors, we had reviewed the 3rd National Ecosystem Survey guide book and consequently, two kinds of analysis method were tested. One was 1/25,000 scale map boundary based analysis and the other was representative mountain area based analysis. In this study we restricted the research area to select reliable surveyed database from whole "2011 National Ecosystem Survey flora database" according to two major criteria. First, an area defined by 1/25,000 scale map boundary and representative mountain area where the number of surveyed flora records should be within top 20%. Second, land cover map should also be built up inside that area. As a result, 25 map boundaries and 25 representative mountain areas were extracted to be analyzed. To limit a boundary for every representative mountain area we had analyzed distribution of environmental factors around that area by manual inspection with SPOT-5 remote sensed satellite image then designated 3km buffer zone from each alien plant location in that area. After then, naturalized index (NI) and urbanized index (UI) was calculated and correlations analysis was carried out. With the result of correlation analysis by map boundary only agricultural land area showed significant value of r (0.4~0.6, correlated) and the rest of factors did not. In the case of representative mountain area, the result showed that agricultural land, road and forest area showed significant value of r (0.6~0.8, highly correlated) which was corresponding to existing researches. Therefore, representative mountain area based method is preferable when using the alien plants database of National Ecosystem Survey for species distribution analysis. And also, considering the way of database utilization is strongly suggested at the first stage of survey planning for promoting active use of national ecosystem survey database.
