본 연구는 한국 대학생 및 대학원생들을 대상으로 장애인에 대한 태도를 연구한 것이다. 총 239명의 남·여 학생들이 본 연구에 참여하였다. 장애인에 대한 일반적 태도를 측정하는 SADP(Scale of Attitudes toward Disabled Persons)를 수정하여 신체장애인과 정신장애인으로 구분한 후 학생들을 대상으로 태도를 조사하였다. 연구결과, 신체장애인이 정신장애인보다 더 호의적으로 평가받았고, SADP의 세 하위척도 상에서도 동일하게 평가받았다. 이전에 장애인을 만나본 적이 있다고 보고한 학생들은 장애인을 만나본 적이 없다고 응답한 학생들보다 더 긍정적인 태도를 보여주었다. 교육연한과 관련하여 대학원생들은 대학생들보다 더 호의적인 태도를 보여주었으나 남·여 학생들 간 태도점수는 통계적으로 유의미한 차이가 없었다. 본 연구의 제한점 및 재활프로그램에 대한 시사점 등이 논의되었다. This study was to investigate differential attitudes of Korean students toward people with disabilities. A total of 239 Korean students participated in this study. The Scale of Attitudes Toward Disabled Persons(SADP) was modified to differentiate mental disabilities from physical disabilities. The results indicated that Korean students showed more favorable attitudes toward people with physical disabilities than those with mental disabilities, and the same holds for the 3 subscales of SADP. Years of education and contact experiences with people with disabilities were found to induce more favorable attitudes toward people with disabilities disregarding the types of disabilities. No gender difference was found in this study. Limitations and implications of the study were discussed.
沸騰熱傳達에서의 發生氣泡에 관한 연구 : 氣泡週期와 直徑과의 關係에 대하여 On the Relation Between Bubble Frequency and Diameter
崔國光 단국대학교 1977 論文集 Vol.11 No.-
New data concerning the frequency and diameter which bubble leave a given bubble site is presented. Three separate regions are suggested by the experimental data, which correlate for each region better than single relationship; (a) for the hydrodynamic region in which the major forces acting on the bubble are buoyancy and drag force;f·D^(1/2)=0.09g^(1/2) (b) for the transition region in which buoyancy, drag, surface tension forces are comparable: f·D^(3/4)=0.44·g^(1/2)(㎝(1/2)) (c) for the thermodynamics region in which conditions during bubble growth predominate:f·D=constant Theoretical explarations for the variation of f with D are proposed for regions (a) and (c).

When a compression loads are given on the outer circle which have eccentricity of e by the center line, compression distribution and stress concentration on the Ring have been studied and compared with the Ring which has same center line., The results of this paper are as follow., 1. The maximum stress increased with the value of by the eccentricity. 2. When the value of eccentricity; e is increased, the stress concentration factor αis grow up.

본 연구는 서울특별시 소재 정신지제(단일장애) 특수학교 12개교 고등부에 재학하고 있는 남·여 다운증 학생 52명을 대상으로 이들의 일반 직업흥미영역을 살펴보고, 성별·학년별·사회연령별로 직업흥미영역을 비교·분석하기 위하여 실시되었다. 「KEPAD 그림직업흥미검사 Ⅰ(2003)」이 본 연구에 사용되었다. 연구결과, 다운증학생들은 7개의 직업흥미영역 중 세탁, 제조작업, 청소, 정리, 음식제공, 대인서비스, 농축화훼 영역 순으로 직업흥미도를 보였고, 남학생은 세탁 영역에서 여학생은 제조작업 영역에서 가장 선호도가 높게 나왔다. 그러나 학년 및 사회연령에 따른 직업흥미 선호도는 통계적으로 유의미한 차이가 없었다. 본 연구의 시사점과 제한점이 논의되었다. This study was performed to identify the vocational interest areas of high school students with Down Syndrome according to the variables of gender, grade and social age. A total of 52 high school students with Down Syndrome participated in this study, and the Pictorial Vocational Interest Test for the mentally retarded, developed by Korea Employment Promotion Agency for the Disabled(KEPAD, 2003), was used. The common vocational interest areas of students with Down Syndrome were as follows: Laundry Service, Manufacturing Industry, Cleaning Service, Arrangement Service, Eating Service, Personal Service, and Horticulture. There was a gender difference in this study in which the male students with Down Syndrome showed more strong vocational interests in the area of Laundry Service, and the female students with Down Syndrome showed more strong vocational interests in the area of Manufacturing Industry. There were no differences in the variables of students' grade and social age. Recommendations and limitations of the study were discussed.
배(Pear)중 Polyphenol oxidase에 관한 연구
조성희,황국섭 中央大學校 自然科學硏究所 1987 自然科學硏究所 論文集 Vol.1 No.-
Polyphenol oxidases were prepared from the various species of pears and observed their biochemical properties. The experimental results were summarized as follows: 1. The enzyme was active with o-diphenols and trihydroxy-phenols, but inactive toward m-diphenols, p-diphenols and monophenols. 2. The optimum pH was 6.5-7.0 3. The Km value of the enzymes were 25mM in Niidak, 31mM in Chojuro, and 67mM in Danbae with catechol as substrate. 4. The optimum temperature was 35℃. 5. Inhibitor studies indicated that sodium diethyldithio carbamate, L-cysteine, sodium bisulfite, L-ascorbic acid and 2-mercapto ethanol were the most potent, but NaCl and E.D.T.A. were impotent relatively. 6. ??, ??, ??, ?? and ??(1mM) activated the enzyme activity, but ?? and ??(1mM) inhibited partialy.
