Characteristics of the China's Power Elites in the 21^(st) Century : Continue or Change?
Kim, Jung Ke 대한정치학회 2005 大韓政治學會報 Vol.13 No.2
This study focused on the backgrounds of the current CCP PB members, and what characteristics changed or continued when compared to the previous one. The subject of research was the top 203 PB members since 1949, a cluster of elites that includes the current 24 PB members. The analytical categories of the backgrounds were: 1) biological backgrounds, 2) educational backgrounds, and 3) work backgrounds. In brief, the results of analysis show all of the 16^(th) PB in their age, growth time, the time of graduated college and joined the Party, or work experience are different from the third generation. However, the 16^(th) PB members have advanced their careers by working on China's economic modernization program, they were technically trained and by profession technocrats in administrative capacities, similar to their immediate predecessors. Therefore, the new leadership will not necessarily translate into distinctive policy orientation.

Penicillium sp.에 依한 α-Galactosidase 生成에 關한 硏究
金鍾國,朴啓仁,愼重燁 경희대학교 부설 식량자원개발연구소 1984 硏究論文集 Vol.5 No.-
The strong α-Galactosidase producing micro-organism was isolated from soil of soybean field and identified as Penicillium janthinellum. The optimum cultural and enzyme condition of P. janthinellum were investigated. The cell growth and enzyme production of P. janthinellum were observed to reach maximum at pH 5.0 in xylose medium and α-Galactosidase of P. janthinellum was produced constitutively. The optimum pH of crude α-Galactosidase was pH 5.0. The optimum temperature of crude α-Galactosidase was 50℃ and the enzyme was inactivated completely at 70℃ in 10 min.

This study aim at the development of the model of probability rainfall for return period by using frequency analysis. In this study, models of frequency analysis are classified to for lowing models : Two-Parameter lognormal distribution, Three-Parameter lognormal distribution, Pearson Type III distribution, Log-Pearson Type III distribution, Extremal Type I distribution. From the comparison of these models with rainfall data, it is found that Extremal Type I distribution is maximum value and Log-Pearson Type IIIf distribution is minimum value.

各種製劑에 使用되는 安定劑의 含有比率이 經時變化에 미치는 影響에 關한 硏究 (I) : 外用製劑에 含有된 防腐劑의 含量測定에 關한 硏究
金尙敏,李啓胄,曺秀悅 同德女子大學校 1969 同大論叢 Vol.1 No.1
The colourimetric determination of benzalkonium chloride or benzethonium chloride in the topical preparations were investigated. The results are as follows: 1) The wave length of maximum absorbence of benzalkonium chloride or benzethonium chloride were 617 mμ. 2) The limits of measurement of benzalkonium chloride or benzethonium chloride were 10~60r/ml. 3) Benzalkonium chloride or benzethonium chloride were precisely determined even in the presence of various components except of coloured matters, dyes and iodine, etc. .

Aeromonas hydrophila 5-3K의 분리 및 Chitin 분해 특성
김광엽,이찬용,이계호 대전대학교 이과대학 기초과학연구소 1997 自然科學 Vol.- No.-
세균에 의하여 강력한 chitin분해 효소를 생산하기 위하여 chitin분해성 세균을 자연환경으로 부터 분리하고 자 스크리닝을 하였다. 경기도 일원의 토양 및 하천에서 수집한 시료 100점 중에서 7주의 chitin분해성이 강한 세균을 분리하였고, 그 중에서 chitin분해능이 가장 우수한 5-3K균주를 선정하여 제 특성을 확인하여 통정한 결과 Aeromonas hydrophilia 5-3K 이었으며 chitin분해 효소 생산을 위한 배양 최적조건을 조사하였고, 생산된 효소에 대하여 황산암모늄 염석과 Sephadex G-100 column chromatography 행하여 부분 정제하였다. Chitin분해 효소의 생산 최적조건은 pH 7.0, 30℃이였고, 효소 생산에서 가장 효과적인 탄소원 및 inducer는 colloidal chit이었다. 유기 및 무기 질소원으로는 peptone과 (NH₄)₂HPO₄가 좋았다. Jar fermentor에서의 액침 배양시 16~20시간 사이에서 안정된 최대의 효소 생산능을 보였고 이때의 효소 활성온 4.0~4,2 units/ml이었다. 조효소는 pH 7.0, 40℃에서 최대 활성을 나타내었다. Aeromonas hydrophilia 5-3K의 Chitin분해 작용은 크기가 비슷한 chitinase와 chitobiase 두가지 효소의 공동작용에 의한 것임을 추정할 수 있었다. For the production of potent chitinolytic enzyme from bacteria, screening was carried out. Of 100 samples from soil, fresh water and sea water collected from the Kyung-gi area, 7 strains of chitinolytic bacteria were isolated. Among them, Aeromonus hydrophila 5-3K showed the highest chitinolytic activity. Culture conditions of Aeromonas hydrophila for the production of chitinolytic enzyme were inverstigated and lytic enzyme was fractionated by the use of ammonium sulfate and Sephadex G-100. Maximum production of chitinolytic enzyme was obtained at pH 7.0 and 30 C with chitin concentration between 0.2% and 1.0%. Conditions for the enzyme production were optimized including fermentor cultivation. The chitinolytic system of Aeromonas hydrophila 5-3K was composed of two enzymes, chitinase and chitobiase.

Three Korean variety of soybeans and five ordinary fermented soybean pastes collected from 5 districts were studied for oligosaccharides. Oligosaccharides in soybean (Bong Eui Variety), meju, and fermented soybean pastes were determined. The changes of oligosaccharides during the meju preparation were investigated. And then oligosaccharides hydrolyzing micro-organism was isolated and identified. The results obtained are as follows: 1) All of the three Korean variety of soybeans were detected for sucrose, raffinose, and stachyose. In case of five ordinary fermented soybean pastes, three samples collected from Seoul, Busan, and Daegu were detected for sucrose, the only one sample collected from Busan was detected for traces of raffinose and stachyose, and the rest was not detected for these oligosaccharides. 2) Bong Eui variety of soybean contained 42.3㎎/g of sucrose, 12.5㎎/g of raffinese, and 32.5㎎/g of stachyose. Meju contained 2.48㎎/g of sucrose, 0.01㎎/g of raffinose, and 0.03㎎/g of stachyose. And then fermented soybean paste contained 0.25㎎/g of sucrose. 3) As the result of steeping and cooking the soybean, the contents of sucrose, raffinose, and stachyose in soybean decreased to 66.9%, 72%, and 69.5% respectively. 4) Oligosaccharides in cooked soybean decreased a little at early stage of fermentation and almost disappeared except sucrose in 40 days. 5) Oligosaccharides hydrolyzing bacteria, strain B-12 was isolated from meju and identified as Bacillus sp.
