β-1, 6-N-아세틸글루코사민 전이효소 군 : 암전이와 악성화의 주역 Actuon in Cancer Metastasis and Malignant Transformation
김철호,김세권 한국키틴키토산학회 1997 한국키틴키토산학회지 Vol.2 No.4
최근 β-1,6-N아세틸글루코사민전이효소(acetylglucosaminyltransferase)활성이 여러 동물조직과 세포에서 검출되었다. 이들 연구는 전이효소와 이로 인해 합성되는 세포표면당쇄가 발생, 분화, 및 암화에 따라 크게 변화되고 있음을 발견하였다. 그러나 이러한 변화의 분자적인 기초와 기능적인 의의를 밝히는데는 앞으로의 과제라 하겠다. 극히 최근에 β-1,6-N-아세틸글루코사민전이효소의 cDNA가 클로닝되어 발현됨으로서 이들 전이효소계의 유전자수중에서의 발현제어와 발현된 당쇄기능과의 상호관계
돼지감자(Helianthus tuberosus L .) 로부터의 알콜 생산을 위한 균주 선발
김철호,유연우,김수일 한국농화학회 1983 Applied Biological Chemistry (Appl Biol Chem) Vol.26 No.2
To investigate the possibility of ethanol production from Jerusalem artichoke tubers (Helianthus tuberosus L.), various yeast strains were evaluated for their potential in metabolizing carbohydrate from Jerusalem artichoke tubers to ethanol. Among them, Kluyveromyces fragilis CBS 1555 showed the highest inulase activity and ethanol fermentability. On the batch kinetic: analysis, K. fragilis also showed the highest in parameters for ethanol production and substrate utilization, although lower than Saccharomyces cerevisiae Y-10 in cell mass yield and ethanol production yield.
미국의 공공정책 결정 과정에 적용되는 현대 협상학의 여러 원칙

Some of the lessons, which are learned from the recent studies on Negotiation and Mediation and currently applied to the US public policy decision making process, are: i) to lower the expectation and goals of negotiation from resolution of conflict, a complete fundamental victory, to its settlement, a partial small victory; ii) to recognize the decision rule of unanimity in every negotiation, meaning, recognition of the veto power of the other party, and recognition of, and willingness to exercise my own veto power; iii) to recognize the necessity of paying attention not only to concern for my own substantive outcome but also to concern for the other party and the desired relationship between them and us.

By the section 659 of the Commercial law, the insurer does not have to pay in case an insured person commits a suicide. However, despite of this section, the life insurance policies state if the insured commits a suicide due to his insanity or after 2 years from the commence- ment of the coverage, the insurer has to pay the insurance money. In this article, it discusses the suicide clauses in life insurance policies. First, it reviews the "suicide after the time period that is specified" through some cases and concludes that it is justifiable to pay the insurance payment which falls into "causes except accident" if the person commits a suicide after the period that is specified. Secondly, if a person commits suicide due to his insanity, he is not subject to the accidental death benefit. It is because even if there is no intent to commit a suicide, he did not die from any "external causes" which is the requisite of "accident". Also, in Jan. 2010, the Financial Supervisory Service amended the life insurance polices and states that the insurer has to pay the accidental death benefit for the deaths caused by insanity. There are issues to be discussed and there needs to be lots of studies and need to be improved.
