Shin, Eun-Ja ;
Journal of Information Management, volume 24, issue 4, 1993, Pages 1~23
The purpose of this study is to investigate and analyze the obsolescence of documents according to their dates, types and locations of publication. The main results are as follows : The half-life of monographs is 12.09 years while those of articles and research papers are 9.68 and 8.93 years, respectively. Moreover, documents are most often cited by researchers within two years since their publication. Lastly, but not the least, the estimated weeding points for monographs, articles, and research papers, assuming that their weeding points have been realized when their accumulated citation rates reach 90%, are 40.15, 32.15, and 29.65 years, respectively.

Moon, Sung-Been ;
Journal of Information Management, volume 24, issue 4, 1993, Pages 43~57
This paper discusses the basic concept of artificial intelligence(AI) and expert system and a particular technique(fuzzy logic) applied to expert systems. It examines expert system as search intermediaries during the past few years, particularly in terms of the following functions: 1) handling certain classes of questions on a particular database, 2) assisting in decision making for selecting databases or search terms, and 3) offering advice while keeping the end-user in the control of the searching process. The limitations and difficulties involved in developing such expert systems are also presented.

Cho, Jae-Ho ;
Journal of Information Management, volume 24, issue 4, 1993, Pages 58~77
Database of journals/books are categorized into bibliographic database and clearinghouse-type databases which tell you locations of original materials. There is such a problem in the latter type of databases that those are not likely to be commercialized, although ultimate purpose which users have is to obtain original materials. We find photocopying service through on-line or full-text databases currently available, but we can't get information which meets our needs only by those databases. This paper describes major database services and how to use them by document type(journal or book). The author also discusses what future information centers utilizing databases should be.
