가스터빈은 브레이턴사이클을 이용한 것으로서 피스톤 왕복엔진과 함께 동력기관으로써 지금까지 사용되고 있으며 특히 경량, 고출력의 장점으로 인해 항공기 엔진의 추진기로서 많이 사용되고 있다. 1905년 프랑스에서 압축비 4.8회전수 4250rpm으로 40HP의 출력을 내는 현재와 같은 형 태의 가스 터빈을 개발한 이후 많은 발달과 함께 2차 대전 후에는 항공용 뿐만 아니라 발전용, 동력용 등 산업용 엔진에도 응용되었다. 세계적으로는 유럽이 가스 터빈에 관한 연구를 미국보 다 앞서 활발히 진행하였으며 1957년 General Electric사의 F-4팬텀에 사용된 J-79터보 제트 엔진을 개발함으로써 가스터빈 엔진분야에 미국이 주도권을 잡게 되었고 많은 전문회사가 가스 터빈 엔진설계 제작에 참여하고 있다. 이와 같이 가스 터빈에 대한 개발연구가 계속 이루어진 것은 가스 터빈이 다른 동력기관 보다 단위 중량당 많은 출력을 낼 수 있고, 각 요소들이 회전 운동을 함으로써 고속운전을 할 수 있고, 부하 변동에 빨리 적응하며, 마찰부분이 적어 윤활유 소비가 적은 장점들이 있기 때문이다. 본 글에서는 이와 같은 가스 터빈 연구개발의 국내외 현황 및 그 전망에 대해서 기술하고자 한다.

The purpose of this study was to analyze physical education purposes perceptions for the parents of student with disabilities. It verified the differences in perception according to three independent variables which were type of disability, level of grade and experience of integrated education. The subjects of this study were 355 the parents of student with disabilities who lived Seoul and Kyunggee province in Korea. A questionnaire designed to measure physical education purpose for the parents of student with disabilities. The reliability of the questionnaire was confirmed by Cronbach's a value and it was 9445. Statistical methods employed in this study were t-test and one-way ANOVA. The results of this study were as follows : first, the parents of student with mental retardation and emotional disorder group showed a higher perception level in all three key concepts and seven major concepts than the parents of student with orthopedic and multiple disabilities group. Second, the parents of student with disabilities who studied middle and high school level showed a higher perception level in the areas of 'environmental coping' than the parents of student with disabilities who studied element school level. Third, the parents of student with disabilities who had experience of integrated education showed a higher perception level in the areas of 'individual development' and 'environmental coping' than the parents of student with disabilities who didn't have experience of integrated education.

The purpose of this study was to investigate the relationship between participation in sports activities and life satisfaction for mothers of children with disabilities. Using a systematic stratified cluster random sampling method, thirteen special school were randomly selected from Seoul and Kyunggi province in Korea. The sample number in actual analysis was 480 mothers of children with disabilities. The questionnaire concerning life satisfaction was developed by Diener, Emmons, Larsen, and Griffin(1983) and consisted of five items. The reliability of the questionnaire was confirmed by Chronbach's a coefficient(a=.873). Statistical methods employed in this study were ANCOVA and multiple regression analysis. The results of this study were as follows ; first, household income, mother's occupation, and time spent on housework had significant effects on the life satisfaction Second, the nature of the child's disability had significant effects on the life satisfaction. Third, the children's education had significant effects on the life satisfaction. Fourth, the degree of life satisfaction ranked higher among mothers who were participating sports activities when compared to mothers who were not engaged in sports activities. Finally, the duration of participating in sports activities effected the life satisfaction but not effect frequency and intensity.

The purpose of this study was to develop regression equations that accurately estimates body fat percentage using relatively easy and inexpensive methods for students with spastic cerebral palsy. Data was collected among 93(male 52 and female 41) students with spastic cerebral palsy in 'J' orthopedical special school, Seoul, Korea. Height, weight, skinfold thickness at two sites(triceps and subscapular), and circumferences at nine sites(neck, chest, waist, thigh, calf, ankle, arm, forearm and wrist) were measured as well as total body bioelectrical impedance analysis(BIA). Statistical methods employed in this study were t-test, Pearson's correlation and multiple regression analysis. The results of this study were as follows ; first, percentage body fat(%BF) of students with spastic cerebral palsy was 14.22%(male) and 16.08%(female). Second, there were a strong correlation between the BIA and fat weight, triceps, subscapular for males, a strong correlation between BIA and weight, fat weight, BMI, triceps, subscapular, circumference(chest, waist, forearm, arm, ankle and thigh) for females. Third, there was a significantly different %BF between students with quadriplegic and diplegic cerebral palsy. Finally, predictive equations were resulted in a relatively good estimation of body fat percentage. These equations accounted for 67.8%(male) and 92.4%(female) of the variance in body fat measured by BIA.

In planning hospitals, one of the important procedure is to assess the total floor area and to decide the layout and proportion of spaces of various departments composing a hospital. For reference to architects in the space program of the coming general hospital buildings, this study attempts to obtain and analyze basic data of the use of space in recent hospital buildings on the basis of the status of medical institute and the medical care forecast. Eleven hospitals as a sample chosen for this study.

The purpose of this study to examine the perceiving of purpose concepts in physical education of college students in the course of special physical education(SPE) on the basis of 22 purpose concepts in Purpose-Process Curriculum Framwork(PPCF) developed by Jewett & Mullan(1977). The purpose dimension consists of 3 key concepts: individual develoment, environmental copying and social interaction which are subdivided into 7 major concepts : physiological efficiency, psychic equilibrium, spatial orientation, object manipulation, communication, group interaction and culture involvement. For a sample survey, this research chose 111 students who had pertinently made out the test sheets to the purpose, out of the 120 Y university students in the course of special physical education and 120 students in the course of physical education of S Univ., D Univ. and D Women's Univ. then analyzed the difference of the perceiving of purpose concepts in physical education caused by major, the gender and he or she had taken the lecture that are related to special physical education. The data were analyzed by t-test, two way-ANOVA test of the SPSSWIN 7.6. On the basis of the results in this study, conclusions are as follows: First, SPE students were differently cognitive of purpose concepts in physical education than the non SPE students. Especially, the SPE students are highly cognitive physiological efficiency, psychic equilibrium and group interaction while non SPE students are highly cognitive of group interaction, spatial orientation and object manipulation. Second, Male students were highly cognitive of purpose concepts in physical education than female students, in both major. Male students are more highly cognitive not only need of physical activities but ratio of participation in physical activities than female students. Third, The group who took a lecture of SPE was differently cognitive of purpose concepts in physical education than the group who not took lecture of SPE. It affects perceiving of purpose concepts in physical education to take lectures which are related to special physical education
