The existing most studies on the apartment sales prices have been limited to relatively small size apartment complexes and have not categorized the apartment complexes based on the number of households. Some of them uses the apartment-related indices such as regional value estimates, sales unit price, and view right values. In the case of Seoul Metropolitan Area, the size of apartment complex has been growing to the level of large complex over more than 1,000 households through new town development, redevelopment and reconstruction. People prefers to choose a large scale complex instead of small complex based on their perception that a large scale apartment complex provides more conveniences in living. The result of this analysis revealed that the variables chosen as important determinants of the hedonic price model for large scale apartment complexes were square meters of apartment unit, rent/price ratio, number of bays, distance to the nearest subway station, and heating system method. This means that the sales price of apartment unit will be higher as the square meters of apartment unit increase, as the rent/price ratio decreases, as the distance to the nearest subway station increases, and as the number of bays increase.

Accepting the necessity for maintaining the objectives of the existing circulation system, the computer-based system could be designed by the system analyst and librarians to gain a variety of improvements in the maintenance, accessibility of circulation records and more meaningful statistical records. If the terminal can be operated on-line, then this circulation data is transmitted directly to the computer, where it may update to the circulation file immediately or alternatively be kept in direct access file for updating in batch mode. on-line system in the circulation operations is "data-collection system" and "Bar-coded label system" Bar-coded label system is simple, quick, and error-free input of data. Attached to CRT terminal is a "light pen" which is hand held and will read a bar-coded label as the pen is passed over the labels (one affixed to the book itself, other carried on the borrower cards). Instantaneously the data concerning transaction is stored in the central mini-computer. It is useful, economical for us to co-operate many libraries in Korea and design borrower's ID code, book no., classification code in the Bar-coded label system by the members of the computer center and the library staff at every stage. As for book loan, the borrowers ID code, book number and classification code are scanned by the bar-code scanner or light pen and the computer decides whether to loan and store the data. The visual display unit shows the present status of a borrowers borrowing and decides whether borrower can borrow.
인접한 단어와 키워드 주제어 정보에 기반한 유사 문헌 검색 시스템 개발
김광영,곽승진,Kim, Kwang-Young,Kwak, Seung-Jin 한국도서관정보학회 2009 한국도서관정보학회지 Vol.40 No.3
유사 문헌 검색 시스템은 추출된 색인어 중에서 어떤 것을 선택하는가에 따라 검색 결과에 많은 차이점이 발생한다. 본 연구에서는 추출된 후보 색인어의 선정의 오류를 최소한으로 하는 방법을 제공한다. 본 연구에서는 유사문헌에서 추출된 후보 색인어들을 이용하여 인접한 단어들의 정보와 추출된 키워드 주제어 정보를 이용하였다. 그리고 관련 저자들 정보와 검색 결과의 재순위화 방법을 이용하여 보다 정확도가 높은 유사 문헌 검색 시스템을 개발하였다. 본 논문에서는 과학기술 학회마을 데이터베이스를 이용하여 실험하였다. 실험과 사용자 평가를 통해서 유사 문헌 검색 시스템의 성능을 입증하였다. The similar bibliographic retrieval system follows whether it selects a thing of the extracted index term and or not the difference in which the similar document retrieval system There be many in the search result is generated. In this research, the method minimally making the error of the selection of the extracted candidate index term is provided In this research, the word information in which it is adjacent by using candidate index terms extracted from the similar literature and the keyword topic information were used. And by using the related author information and the reranking method of the search result, the similar bibliographic system in which an accuracy is high was developed. In this paper, we conducted experiments for similar bibliographic retrieval system on a collection of Korean journal articles of science and technology arena. The performance of similar bibliographic retrieval system was proved through an experiment and user evaluation.
개인화 검색시스템에 관한 연구 - 과학기술학회마을을 중심으로 -
김광영,곽승진,Kim, Kwang-Young,Kwak, Seung-Jin 한국도서관정보학회 2010 한국도서관정보학회지 Vol.41 No.1
이 연구에서는 기존의 과학기술학회마을에서 제공하고 있는 일반 검색서비스에 대해서 분석하고 이를 기반으로 과학기술학회마을 논문 서비스에 적합한 개인화 검색서비스들을 개발하였다. 즉, 질의어 기반의 개인화 검색시스템, 논문의 공동 저자 기반의 내비게이션 시스템, 논문의 저자 키워드 기반 주제어 자동 추천 시스템과 유사한 사용자 자동 추천 시스템들이 있다. 이 연구에서는 설문 조사를 통해서 KISTI 과학기술학회마을 논문 서비스에 적합한 개인화 서비스를 모색하였다. In this research, we analyze about the general service provided by Society of Korean journal articles of science and technology. Personalized retrieval services which are suitable to the articles service were developed based on this. That is, there are personalized retrieval system based on user's keyword, authors navigation system, automatic topic recommendation system based on author's keyword, and similar user automatic recommendation system. In this research, personalized service methods being suitable to the articles service of Society tries to be considered through the user survey.
