도서관 자동화 시스템 개발로 이용자가 책을 직접 찾지 않고, 대출하고자 하는 책을 PC에 입력하면 자율주행으로 책이 있는 서가로 이동, 딥러닝 기반의 로봇팔로 책을 잡고 기존 위치로 복귀하여 자동으로 대출과 운반이 가능한 로봇의 시스템을 제안한다.

In this study, a SOHO (Small Office Home Office) bankruptcy prediction model is proposed using Modified Bagging Predictors which is modification of traditional Bagging Predictors. There have been several studies on bankruptcy prediction for large and middle size companies. However, little studies have been done for SOHOs. In commercial banks, loan approval processes for SOHOs are usually less structured than those for large and middle size companies, and largely depend on partial information such as credit scores. In this study, we use a real SOHO loan approval data set of a Korean bank. First, decision tree induction techniques and artificial neural networks are applied to the data set, and the results are not satisfactory. Bagging Predictors which has been not previously applied for bankruptcy prediction and Modified Bagging Predictors which is proposed in this paper are applied to the data set. The experimental results show that Modified Bagging Predictors provides better performance than decision tree inductions techniques, artificial neural networks, and Bagging Predictors.

본 논문에서는 전자 도서관을 위한 저작권 보호 기능을 가진 전자책 교환 시스템 개발을 소개한다. 전자책은 암호화에 기반한 리더 시스템을 통해 저작권이 안전하게 보장되도록 하는 디지털 컨텐츠 유통을위한 기술 표준이다. 전자책의 안전한 유통과 사용을 위해서 전자 도서관은 보유한 디지털 컨텐츠에 대해 적법한 사용 권한을 이용하여 대출을 해 줄 수 있어야 한다. 이를 위해 본 연구에서는 EBX(E-Book Exchange) 프로토콜에서 정의한 대출 기능을 구현한 도서관 서버를 개발하였고 전자책 리더 클라이언트를 통해 이러한 권한을 보호하면서 사용자가 전자책을 이용할 수 있게 지원하는 기능을 구현하였다.

This study was to suggest the problems and the improvement plan of Digital Library System (DLS) which has solved the library management and has supported the data building for resource sharing in school libraries since 2001. The 9 DLS committees were interviewed about the current situation of DLS use and the problems of DLS system in the 6 areas of acquisition, cataloging, circulation and discharge, inventory, library statistics, and searching interface as the research methods. Based on the interviews, the improvement plans were suggested as followed. In acquisition, it was to need the acquisition system development and online purchase for users. In cataloging, the improvement of data quality management, and indexes and vocabularies control for upgrade of searching function were needed. The advanced circulation speed in circulation, the restoration of discarded data in inventory and the exact statistic data in library statistics were need to improve the DLS. This study would contribute to the betterment of DLS and increase the use of DLS.

The phone number used for advertising messages and voices used as bait in the voice phishing crime access stage is being used to send out a large amount of illegal loan spam, so we want to quickly block it. In this paper, our system is designed to block the usage of the phone number by rapidly restricting the use of the voice spam phone number that conducts illegal loan spam and voice phishing, and at the same time sends continuous calls to the phone number to prevent smooth phone call connection. The proposed system is a representative collaboration model between an illegal spam reporting agency and an investigation agency. As a result of developing the system and applying it in practice, the number of reports of illegal loaned voice spam and text spam decreased by 1/3, respectively. We can prove the effectiveness of this system by confirming that.

[ $\circ$ ]최근 일본에서는 계속되는 부동산경기 침체로 금융기관의 부실채권이 크게 늘어남으로써 금융시스템의 안정성을 위협하고 있음 $\circ$ 우리나라에서도 1992년 이후 부동산경기가 부진한데다 건설업체의 난립에 따른 과당경쟁으로 건설업체의 부도가 늘어나고 금융기관 부실채권이 증가하였으나 그 정도는 일본보다 훨씬 약함 -일본은 지가(6대 도시)가 1995년 현재 정점 대비 $49\%$ 수준으로 하락한 반면 우리나라는 $89\%$ 수준으로 하락하는데 그침 -또한 우리나라에서는 부동산업에 대한 대출이 금지되어 있어 전체 부동산관련 대출배율도($17\%$)도 일본($29\%$)보다 작을 뿐만 아니라 금융기관의 총대출에 대한 부실채권의 비율도 $1\%$ 로서 일본($26\%$)보다 낮음 $\circ$ 따라서 우리나라에서의 부동산경기 부진이 일본에서처럼 금융시스템의 안정성을 위협하는 사태로 발전할 가능성은 크지 않은 것으로 보임
