최길성,김승연 大田産業大學校 2000 한밭대학교 논문집 Vol.17 No.1

본 논문에서는 XML 문서의 구조적 정보를 표현하는데 적합한 객체지향데이터베이스 관리시스템 O2를기반으로 하는 XML 저장관리기를 설계하고 구현한다. 이를위해 효과적인 XML 문서의 저장과 추출, 이 미지관리 및 수정된 문서들의 버전 관리 등을 지원하는 객체지향 모델링을 제시하고, 이를 이용한 XML 저장관리기를 구현한다. 구현 한 XML 저장관리기는 외부 애플리케이션과의 인터페이스 역할을 하는 저장관리기, XML 문서를 실제로 데이터베이스에 저장하는 XML 인스턴스 저장기, 데이터베이스 내에 저장되어 있는 XML문서에 대한 추출을 담당하는 XML인스턴스 관리기, 문서의 내용 및 구조 정보에 대한 인덱스를 생성하고 관리하는 XML 인덱스 관리기 그리고 질의를 처리하는 질의 처리기로 구성된다. In this paper, we design and implement a XML repository manager(XRM) based on OODBMS that supports structured information retrieval of XML documents. We also propose an object oriented modeling to store and fetch XML documents, to manage image data, and to support versioning for the XRM. The XRM consists of a repository manager that maintains the interfaces for external application programs, a XML instance storage manager that stores XML documents in the database, a XML instance manager that fetches XML documents stored in the database, a XML index manager that creates index for the structure information and the contents of documents, and a query processor that processes various queries.

This experiment is a quantitative experiment where insoluble Vitamins E and K are extracted from the yolk of the spawning which was fed by by-products of tangerine, carrot, or Japanese apricot. Finally the purpose is to raise contents of the insoluble Vitamins E and K inside the yolk of the spawning. The saponification method through α, α - dipyridyl was used to determine the content of Vitamin E. Diethyl dithiocarbamate assay was used to examine the content of Vitamin K. The contents of Vitamin E in egg yolks of chicken fed by by-products of tangerine, carrot, or Japanese apricot increased 2 - 3 times compared to control egg, while the contents of Vitamin K almost no changed. 본 실험에서는 감귤, 매실, 당근의 껍데기로 감귤박, 매실박, 당근박을 먹여 산란계의 난황에 들어있는 Vitamin E와 K 함량을 높이고자 했다. Vitamin E 추출방법에는 검화방법인 α, α -dipyridyl에 의한 비색정량법을 사용하였으며 전처리 과정 중 석유 ether를 가하여 층을 분리하는 과정과 증류수를 가하여 층을 분리하는 과정에 있어서 신중을 가하였고 신속한 시료 전처리과정이 요구되었다. Vitamin K 추출에는 Diethyl dithiocarbamate에 의한 방법이 사용되었다. 실험결과 일반난황에서의 Vitamin E 함량보다 실험난황에서의 Vitamin E 함량이 2배 이상 높아졌음을 알 수 있었던 반면 Vitamin K의 함량은소량 증가하여 큰 변화가 없었다. 위의 결과를 통해서 난황에 이전된 Vitamin E의 종류가 무엇이며 어떠한 형태의 Vitamin E가 이전이 많이 되었는지를 확인하는 실험이 필요할 것이다. 이러한 추가적인 실험이 이루어졌을 때 상업적으로 이용한 가치가 있는 가를 고려하여야 할 것이다.

This study aims to develop a conceptual model on the strategic employment adjustment in Korean financial institutes. The model basically rooted in gaining competitiveness in financial institutes, proposes the criteria of direction, scope, speed and finally objects of employment adjustment with some theoretical background. Specifically, according to this paper, first, the decision of the direction of employment adjustment should be based on the criteria of technical rationality(business fit and internal fit). Second, the decision of the scope of employment adjustment had to be rooted in strategic uncertainty of industry driving force. Thirdly, the decision of the speed of employment adjustment mainly dominated by the degree of required innovation. Finally, as a critical issue, the decision of the objects of employment adjustment shuuld be depend on the business domain in the future and strategic posture to reach out there. Some discussions and implications are also suggested.
