한말 신문광고를 유심히 살펴보면 최최의 전문적인 서적상이라 할 '대동서시'가 문을 연 1896년 이후부터 한일합방 때까지의 15년간, 경향 각지에 무려 70여곳의 서점이 있었던 것으로 확인된다. 이는 경술국치를 전후한 시기에 고작 10여개의 서점이 서울에서 영업을 하고 있었다는 지금까지의 통설을 크게 수정한다는 점에서 눈길을 끈다.

This study investigates time series data on internet banking systems and business performances for 5 large-scale banks : Kookmin, Woori, Hana, City, Shinhan. These banks have the common features that they merged with other banks around 2000, hence they experienced massive IS integration between banks. This study adopted VAR and VECM for identifying Granger causality between the quality of internet banking systems and the performances of banks(operating revenue and cost). The main results are as follows. First, internet banking system impacts positively on the revenues as well as costs of banks. Second, the improvement of internet banking system is instigated by cost part more than revenue part. Hence, the results imply that banks tries to reduce operating costs via internet banking systems, however the systems rather increased the costs of banks, although the systems increased operating revenues of banks too.

본 논문은 단기신용등급의 변화가 주가에 미치는 영향을 실증적으로 고찰함으로써 신용등급의 정보기능과 우리나라 주식시장의 효율성을 함께 검증하는데 그 목적이 있다. 단기신용등급이 변화한 104 상장기업을 대상으로 한 실증분석 결과, 우리나라의 주식시장이 기업의 재무상태와 영업상태를 수시로 주가에 반영하여 신용등급변화의 발표 자체가 갖는 정보효과는 극히 작다는 것을 보임으로써 주식시장의 효율성이 지지되었다. 신용등급변화의 정보효과가 평균적으로는 영에 가까우나 발표일 이전에 관련 정보가 주식시장에 적게 반영된 기업의 경우 신용등급변화의 정보효과가 크게 나타남을 보여줌으로써 신용등급변화의 발표가 기존 정보의 오차를 수정하는 효과가 있음을 시사하였다.

Many electronic document files, including Microsoft Office Word (MS Word), have become a major issue in various legal disputes such as privacy, contract forgery, and trade secret leakage. The internal metadata of OOXML (Office Open XML) format, which is used since MS Word 2007, stores the unique Revision Identifier (RSID). The RSID is a distinct value assigned to a corresponding word, sentence, or paragraph that has been created/modified/deleted after a document is saved. Also, document history, such as addition/correction/deletion of contents or the order of creation, can be tracked using the RSID. In this paper, we propose a methodology to investigate discrimination between the original document and copy as well as possible document file leakage by utilizing the changes of the RSID according to the user's behavior.
