金弘泰,孫廣翼,韓健淵 경북대학교 산업기술연구소 1993 産業技術硏究誌 Vol.21 No.-

This paper describes the use of the finite element analysis in the development of a two-dimensional(in plan) hydrodynamic simulation model that solves the Saint-Venant equation. A finite element model consists of pre-processing, analysis processing and post-processing. The model has been tested with tow dimensional problems, including surge flow, flow through abrupt contraction and outfall flow. The finite element model shows a stable and efficient results for various situations. The model will provide a good contribution to the numerical analysis of two dimensional Saint-Venant equation.

이봉학,홍창우,김정태,김연경 강원대학교 석재복합신소재제품연구센터 1997 석재연 논문집 Vol.2 No.-

제강슬래그는 환경오염 방지와 에너지 절감 효과를 얻을 수 있는 콘크리트로 재활용 될 수 있다. 반요인실험법을 사용하여 제강슬래그를 굵은골재에 일정한 비율로 혼입한 콘크리트의 최적배합설계 제시를 위한 예비 실험에서 제강슬래그의 굵은골재 혼입율, 물-시멘트비, 잔골재율, 슬럼프와 같은 주요 변수와 변수 사이의 2차 상관관계를 파악하였다. 예비실험을 한 결과 제강슬래그를 굵은골재로 100%까지 혼입했을 때 제강슬래그를 혼입한 콘크리트의 강도 발현에 가장 변수는 물-시멘트비로 분석되었고, 제강슬래그의 굵은골재 혼입율은 강도 발현에 가장 중요한 변수는 물-시멘트비로 분석되었고, 제강슬래그의 굵은골재 혼입율은 강도 발현에 거의 영향이 없는 것으로 분석되어 제강슬래그를 콘크리트의 굵은골재로 대체할 수 있다는 것을 알게 되었다. 변수 사이의 2차 상관관계에서는 제강슬래그의 굵은골재 혼입율과 잔골재율의 상관관계가 콘크리트의 강도 발현에 가장 큰 영향을 미치는 것으로 나타났다. 목표압축강도를 만족하는 제강슬래그를 혼입한 콘크리트의 최적배합설계는 제강슬래그의 굵은골재 혼입율, 물-시멘트비, 잔골재율에 관하여 제시하였다. An experimental study os performed to examine the feasibility of using wastes steel furnace slag consturction materials and its utility as a replacement for the natural resources to prevent the economic loss was investigated. A half factorial exprements was performed with the variables of W/C ratio, S/A, Coarse aggrigate/Slag ratio and slump as a preliminary study for optimum mix design of concrete. The results show that the W/C ratio and Slump ratio are the most important factor to the concrete strength. The substitute of waste Slag up to 100% has little infleunce, saying that it can substitute te coarse aggregate without damaging the concrete properties.

심경원,김지연,서희선,이홍수,이상화,강지현 대한비만학회 2002 The Korean journal of obesity Vol.11 No.2

연구배경 : 국내 비만 여성을 대상으로 비용이 적게 들고 단순하면서도 보다 정확하게 체지방률을 추정할 수 있는 체지방률 추정식을 작성함으로써 쉽게 체지방률과 조절해야하는 지방의 양을 판단할 수 있도록 하고자 한다. 방법 : 이대목동병원 비만클리닉을 처음으로 내원한 19세 이상의 성인 여자 607명 중 체질량지수가 25 kg/㎡ 이상인 500명을 연구대상으로 하여 목, 가슴, 허리, 엉덩이, 대퇴, 하퇴, 발목, 상완, 전완, 손목의 10부위의 둘레와 생체전기저항분석법 (bioelectrical impedance analysis, BIA) 방식의 체성분 분석기를 이용하여 체지방률을 측정하였다. 체지방률 추정식을 구하기 위해 BIA에 의한 체지방률을 종속변수로 하고 , 신체 둘레 계측기 및 신장, 체중, 체질량지수, 연령을 독립변수로 하여 단계별 다중회귀분석 (multiple stepwise regression)을 시행하였다. 결과 : 신장과 체중, 연령, 체질량지수 및 신체 둘레 측정치 중 체지방률을 반영하는 지표는 체질량 지수, 전완둘레, 신장, 엉덩이 둘레, 하퇴둘레였고, 이 다섯가지 지표를 이용한 체지방률 추정식은 66.1%의 예측력과 2.86%의 측정 오차를 나타냈다 (R^2=0.661, SEE=2.86). 결론 : 비만한 성인 여성에서 신장과 체중, 연령 및 신체 둘레 계측치를 이용한 본 연구의 추정식은 체지방률(%)을 적은 오차범위로 비교적 정확하게 반영하였다. Background : This study was conducted to develop a regression equation that accurately estimates body fat percentage using relatively easy and inexpensive method in adult obese Korean women. Method : Data were collected among 500 obese Korean women visiting obesity clinic in Ewha woman's university Mokdong hospital, Seoul, Korea. Height, weight, and circumferences at ten body sites (neck, chest, waist, hip, thigh, calf, ankle, arm, forearm, wrist) were measured s well as total body bioelectrical impedance. Results : The full regression equation estimates body fat percentage included six variables : BMI, forearm circumference, height, hip circumference, thigh circumference. This equation accounted for 66.1% of the variance in body weight measured by bioelectrical impedance, and their standard error of estimate was 2.86%. Conclusion : For the obese Korean women in this study, circumference measurements provided a s relatively good estimation of body fat percentage.

마르크스主義的 從屬理論의 從屬克服論理에 관한 批判的 考察

金柄五,元弘淵,朴洪潤 江陵大學統一問題硏究所 1986 統一問題硏究 Vol.3 No.-

Students of dependency have struggled over the past decade to integrate their ideas with a theory of Marxism. Their work has opened up new questions and criticisms. Conciderable debate has ensued. An introductory review of the debate in general offers a summary of the principal criticisms of radical dependentistas. The dependent approaches assumes and anti - imperialist stance, yet they are distinguishable through non- Marxist and Marxist categories. These categories are suggested because many of the modernization theories are incorporated into a theory of dependency. Dependency is a centuries - long and ever - continuing process of historical structuring, as Frank and the entire " world systems" school have demostrated, of the economic and social structures of societies impacted by international capitalist development. In Marxist dependentistas perspectives, excessive deterministic zeal at the level of macro political economy has a far more serious consequence than explanation by conspiracy ; and this is the implication that the importance of internal social forces does not permit dependent societies to write their own histories. Five of our observations pertain to an assessment of Marxist perspectives 1. a debate on dualism 2. a debate on dependency and underdevelopment 3. a debate on the possibility of the development with dependence and capitalism 4. a debate on the shift over socialism 5. a debate on the logic of revolution.

The purpose of this study was to evaluate the accuracy of CPR skills and the satisfaction of CPR Training targeted for college students. Also, this study made comparative study of nursing students and non-nursing students. The sample consisted of 248 students(132 nursing students, 116 non-nursing students). CPR Training was designed by two components which were a lecture and demonstration by one professor and individual practice 표 instructors. As tool of measurement estimation satisfaction of CPR Training questionnaires were developed based on educated contents. The accuracy of CPR skills were checked by SkillReporter CPR training manikin. Collected data were computerized and analyzed by SPSS-WIN program. The results were as follows : 1. The skills of CPR were cardiac compression 92.79 times/min, correct cardiac compression rate 90.85%, ventilation 9.93 times/min. correct ventilation rate 79.34%. 2. The mean of the accuracy of CPR skills were 2.94(SD .87). 3. When errors were analyzed, the highest item was stomach distension(51.2%) of ventilation skills and too little(70.6%) of cardiac compression skills. 4. The mean of the satisfaction of CPR training were 2.87(SD .17), the highest item of the satisfaction of CPR Training was practice. 5. We found significant statistical differences based on the accuracy and the error, non-nursing students were high in correct cardiac compression per minute(t=3.615, p=0...) and ventilation too much(t=4.292, p=.000), nursing students were high in correct ventilation rate(t=-3.885, p=.000) and cardiac compression too shallow) t=-2.842, p=.005).
