Purple Bacteria의 광합성 과정에 관한 연구
김수자 慶熙大學校 1983 論文集 Vol.12 No.-
The mechanism of NAD^+ photoreduction was studied with chromatophore prepared from a purple bacteria, R. rubrum. The light dependent reduction of pyridine nucleotides was specific for NAD^+ in contrast to the plant system. NAD^+ photoreduction in purple bacteria was affected by the external electron donors such as succinate, TMPDH^-_2 and H_2. A series of high energy compounds could also derive the NAD^+ reduction in chromatophore. the co-presence of ADP-Pi and NAD^+ exhibits mutual inhibition in reduction and phosphorylation. The inhibition of NAD^+ reduction by ADP was completely reversed by DCCD, an energy transfer inhibitor. All the experimental evidences indicate that in purple bacteria, the NAD^+ reduction system and ATP synthetic system share a common high energy intermediate.

토끼근육 L-α-Glycerophosphate Dehydrogenase의 활성도에 미치는 N^1-Dodecylnicotinamide Chloride의 농도의 영향
김수자 慶熙大學校 1984 論文集 Vol.13 No.-
The inactivation of rabbit muscle L-α-glycerophosphate dehydrogenase by N^1-dodecylnicotinamide chloride was shown to proceed in two different mechanisms depending upon the inhibitor concentration, At low inhibitor concentration, the reversible inhibition was followed by the time dependent irreversible inactivation caused by some irreversible binding between enzyme and inhibitor. At the inhibitor concentration as high as one-tenth of its CMC, the enzyme inactivation was enhanced anomalously. This abrupt inactivation process was discussed on the basis of the enzyme con-formation changes caused by the interaction similar to that important in the micellization of long chain nonpolar compounds.

2,4,6-Trinitrobenzenesulfonic acid 반응에 의한 효소 활성도 측정
김수자,이승주 慶熙大學校 1983 論文集 Vol.12 No.-
A new simple assay method for the peptidyl-dipeptide hydrolase using 2, 4, 6-Trinitrobenzenesulfoic acid was developed and optimum conditions were determined. At the condition studied, this assay was found to be more sensitive than other spectrophotometric methods.

Glutamate-Glutamine 변환반응에서의 ATP 재생산계에 관한 연구
김수자,한지영 慶熙大學校 1993 論文集 Vol.22 No.-
The conversion of glutamate to glutamine by glutamine synthetase was studied using ATP regenerating system which is consisted of coupled pyruvate kinase-phosphoenolpyruvate system and immobilized ATP. Two new bioactive polymeric ATP analogs, poly-glycidylmethacrylate-ATP and copoly-glycidylacrylate-N-vinylpyrrolidone-ATO were synthesized and were found to be regenerated efficiently in glutamine synthetase-pyruvate kinase regenerating system. Optimum conditions for the Glu-Gln conversion using ATP regenerating system were established and extended applications of synthetic polymeric coenzyme derivatives in the continuous synthesis of useful substances in membrane bioreactor were suggested.

L-Alanine Dehydrogenase의 정제와 특성에 관한 연구
김수자,김경미 慶熙大學校 1990 論文集 Vol.19 No.-
L-Alanine dehydrogenase was purified from Streplomyces phaeochromogens KCTC 1174, by ultrasonication, ammonium sulfate fractionation and Blue-Sepharose CL-6B affinity chromatography. The enzymc catayzed amination and deamination showed basic pH optimum(pH 9.5 and 10.5, respectively). The enzyme was specific for the coenzyme NAD' and L-alanine for substrate in the deamination reaction. The enzyme was inhibited by Cu^2+ and Zn^2+ and by 2,3-diamino propanoic acid. The enzyme catalyzed amination is rapidlly inactivated by the additon of p-chloromercuribenzoate and restored by the addition of L-cyctein suggesting the involvement of the sulfhydryl group in enzymic catalytic reaction.

女高生들의 衣裳態度와 Design 選好에 나타난 性格特性의 硏究
金秀子 啓明大學校 生活科學硏究所 1984 科學論集 Vol.10 No.-
After the students' liberation from the uniform regulation, I reached the following conclusions about the personalities and appetites of female high school students for design in the dressing. 1. Girls who prefer a free style of dressing like a well-fitting size and an active style when they choose skirt and pants. 2. The impulse expressed see through or exposing materials is nothing more than curiosity which is the character of a youngster. And it is normal. 3. They put their main value on the design of the clothing especially when they select their parents' advice. 4. They generally select a single color, non figured clothes, and select diverse forms, according to season and use. In arrangement of color, they like a distribution of bright and gay colors among similar colors. This all has to do with their sense of dentity. 5. Girls who are considerate and hospitable expressed agreement with the liberation of students from uniforms. 6. Positive students have felt more difficulty psychologically in their expression through dress since being liberated from uniforms, and they feel that school regulations are stronger now than in the days of uniforms. According to the above, come to the following conclusion. Female hight school students who have a youthful character are positive in social change. In the case of their dress it can be expected that will never bring about any big social problem because of sound principles in dress. In their personality, they have strong psychological sympathy because they are young. But I think it does not have any effect on the social problems occured by youngsters.

敎職者들의 衣服 디자인 選好 및 衣生活 態度와 性格과의 相關性 硏究
金秀子 啓明大學校 生活科學硏究所 1986 科學論集 Vol.12 No.-
The functions of clothing are increased with various ways of life, and social changes, and it seems that private social position, occupation, status, interest, character and feeling are derived from clothing. The clothing should be designed to fulfill its functions, thus, the research leads to the following results to satisfy its importance taking a social part. 1. Those who like sporty fashions are social, and seem to be masculine, so their favorite fashions and character are related notably to each other. 2. Those who like slant-lined designs better in one-piece composition than perpendicular of horizontal-lined are prudent. 3. Those who like feminine fashions than sporty ones show higher stability, responsibility, and sympathy than the latter, so their favorite designs are related notably to their characters. 4. Those who seem to behmasculine like straight-line details better than curved ones. 5. Those who wear blouse show higher sympathy, while those who wear simple T-shirts seem to be masculine. 6. Those who are social and active like dark colors, so the favorite colors are related to their characters. 7. Those who like sorts of cotton which is seemed harsh and to wash seem to be masculine, so the fabrics they like are related to their characters. 8. Clothes patterns that they like are not related to their characters.
