방향족 케톤에 있어서 카르보닐 신축진동에 미치는 치환기의 영향(ll)-3-페닐시드논
尹炳曦,洪淳瑛 漢陽大學校 基礎科學硏究所 1983 基礎科學論文集 Vol.2 No.-
페닐기에 치환기를 도입시킨 9종류의 치환 3-페닐시드논을 대상으로 하여 카르보닐 신축진동에 미치는 치환기의 영향을 적외선 분광 분석법으로 조사하였다. 다른 방향족 케톤에서와는 반대로 전자흡인치환기가 카르보닐 신축진동수를 감소시키는 결과가 나타났다. 또한 치환기와 신축진동수의 변화사이에 Hammett의 관계식이 잘 적용되었으며 치환기의 영향이 다른 방향족 케톤에서 보다 훨씬 큰 사실이 발견되었다. 이런 결과를 시드논의 특이한 분자구조와 관련시켜 고찰하였다. The correlation between infrared carbonyl stretching frequency with substituent in 3-phenylsydnone has been investigated. The Hammett rule was applied well to this correlation. However, in contrast with other aromatic ketones the carbonyl stretching frequency was decreased by electron-withdrawing substituents. This observation was rationalized by means of a structural feature of sydnone ring.
Cataloging in Publication (CIP) 및 그 도입에 관한 소고
洪淳英 이화여자대학교 한국문화연구원 1983 韓國文化硏究院 論叢 Vol.42 No.-
The idea to make the cataloging information available at the time of cataloging had been thought of by many librarians and tried out in various forms. Cataloging in publication is the latest outcome of this very idea. This not only holds essential cataloging information in the new publication, but also has come to provide other benefits to librarians, publishers, and library users. Since CIP was started by the United States in 1973, many countries are now utilizing the program and a set of practical recommendations for CIP program was prepared at the 1982 IFLA meeting. It is the purpose of this paper to review the CIP program and several points that might be raised if it were put to trial in Korea. In view of geographical and organizational consideration, the centralized operation with the National Central Library as the center would be perhaps the ideal choice for Korea; NCL is receiving every new publication under the Copyright Act and it also is experimenting KORMARC which is expected to be in utilization in the near future. In addition, professional cooperation and assistance from library associations to the center will be essential to make the program professionally sufficient. Although the recently stabilizing publishing business will encourage publishers understanding and cooperation for the program, their compulsory participation similar to that in the Copyright Act might be necessary.
