안전한 인덱스 검색 프로토콜은 검색어에 대한 트랩도어를 사용하여 암호화된 문서의 인덱스를 검색하는 것이다. 그것은 비 신뢰적인 서버 관리자에게 검색어를 드러내지 않고 검색하여 그 결과 외엔 문서에 관한 어떤 정보도 알수 없게 하는 것이다. 무수히 많은 안전한 검색 프로토콜들이 제안되어져 왔으나, 이것들은 단지 개인 사용자와 서버와의 검색 과정만을 고려하였다. 그러나 실제로 계층적인 부서가 많은 기업이나 그룹과 같은 조직체들은 그룹의 공유 문서에 대한 검색 환경이 더 많이 요구되어진다. 따라서 이 논문에서는 그룹 키가 새로이 갱신되었을 때 기존문서의 재 암호화 없이도 검색 가능한 안전한 인덱스 검색 프로토콜을 제안한다. A secure index search protocol let us search the index of encrypted documents using the trapdoor for a keyword. It enables an untrusted server to learn nothing more than the search result about the documents without revealing the keyword. A lot of secure search protocols have been suggested but they only considered the search between a single-user and a server. In real organizations such as government offices or enterprises where exist many hierarchical departments, the search system for groups is arisen more often. In this paper, we construct secure index search protocols for hierarchical group settings without re-encryption of the old encrypted documents when group keys are re-keyed newly.

박현아 ( Hyun Ah Park ) 현대영어교육학회 2008 현대영어교육 Vol.9 No.3

The purpose of this study is to report on how digital english textbooks have been actually used in elementary school. The study conducted the following surveys. The digital english textbooks were evaluated according to three criteria-contents, designing instruction, designing functions. Three schools participated in the research. Teachers in those schools were interviewed individually and students answered to the given questionnaires. The major findings are as follows. The TPC (Tablet Personal Computer) was the main media to operate the digital textbooks. However, it turned out that it was difficult for users to run the various activities since it had lack of mobility. Regarding the current digital english textbooks, they had several mistakes and errors. Many teachers and students who were interviewed responded that to use TPC freely in class, major improvements should be made: it should be more convenient and easy to use. In addition, it needs to include more useful functions such as LMS (Learning Management System). The mobility of TPC is also another factor to be considered. Despite these several drawbacks, the digital english textbooks have great potential to be good material if enough contents are supplied to meet the various level or needs of students and well equipped for the jobs which can reconstruct the contents in accordance with the user`s convenience.

영어의 현재완료와 러시아어의 완료상/불완료상

This paper examines the relationship between English present perfect(PP) and Russian perfective/imperfective. Traditionally the semantic invariant of English PP was considered current relevance and Russian perfective was believed to be fitted for that meaning. However, some sub-meanings of current relevance are in fact closely relevant to Russian imperfective. Moreover, based on the recent corpus studies, English PP is often combined with a range of adverbials including past dates and times and is favoured for introduction of new or unexpected discourse information. Given the extensions in the uses of the PP and evidential/mirative functions of imperfective, there is an obvious correspondence between English PP and Russian imperfective as well.

2002년 11월 대한민국 전자정부의 공식출범을 비롯하여 최근 IT 839 전략 등에 힘입어 차세대 IT 분야의 급속한 발전은 바야흐로 유비쿼터스 컴퓨팅 시대로의 진입을 가속화 하고 있다. 최근에는 이것을 뒷받침 하는 기술 분야의 하나인 BcN(Broadband Convergence Network) 역시 그 연구에 박차를 가하고 있으며, 이것의 단말기 역할을 하는 이동성 있는 모바일 폰 기술 역시 급속도로 발전하고 있다. 하지만, 이런 기술 발전과는 달리 그 이면에는 개인정보보호의 침해라는 문제가 있다. 기술의 발전에 비례해서 개인정보 침해 역시 고도화, 전문화되어 급속도로 증가하고 있는 것이다. 본 고에서는 개인정보의 개념부터 먼저 살펴본 후, 모바일 폰의 표준화 현황 및 기반 기술과 응용 서비스 기술을 분석하여 문제점을 도출하고 그 대응 방안을 모색한다. 현재 서비스들이 하나의 소형화된 기기로 집적화되어 가고 있는 추세에서 휴대형 정보기기에서의 개인정보보호를 위한 대안이 절대 한 가지 메카니즘 만으로는 부족하며, 종합적인 보안 기술의 집합체를 이루어야 한다는 사실을 알 수 있게 된다.
