In order to clarify the impact of variation of albedo on the atmospheric boundary layer caused by the density of building in urban areas, both satellite data analysis and numerical experiments were carried out. Utilized satellite data were multi-spectral visible data detected by the Korea Multi- Purpose Satellite -2 (KOMSAT-2), and the numerical models for the estimation of surface heat budget are Albedo Calculation Model (ACM) and Oregon State University Planetary Boundary Layer model (OSUPBL). In satellite data analysis, the estimated albedo in densely populated building area is lower than other regions by 17% at the maximum due to the shadow effect of skyscraper buildings. The surface temperature reached 43.5oC in the highly dense and tall building area and 37.4oC in the coarse density area of low buildings, respectively. However, the low albedo in densely integrated building area is not directly related to the increase of surface air temperature since the mechanical turbulence induced by the roughness of buildings is more critical in its impact than the decrease of albedo. 도심지 빌딩에 의한 그림자가 대기경계층에 미치는 영향을 파악하기위하여 위성자료 분석과 수치실험을 실시하였다. 연구에 사용된 위성은 한국다목적위성(KOMSAT-2)의 가시자료이며, 수치모형은 다중반사도 계산을 위한 반사도계산모형과 지표면 열수지를 계산하기 위한 오레건주립대학교 경계층 모형의 2가지이다. 위성자료 분석에서 고층빌딩이밀집한 지역은 그렇지 못한 지역에 비하여 반사도가 최대 17% 낮게 산정되었다. 이는 건물의 그림자가 원인으로 작용한다. 그리고 반사도의 일변화는 태양고도에 따라 다르며, 정오에 가장 작은 값을 나타낸다. 건물 밀도가 높은 경우 지표면 온도가 43.5oC까지 상승하는데 비하여 건물 밀도가 낮은 지역의 경우 지표면 온도는 37.4oC까지 상승한다. 그러나높은 빌딩에 따른 기계적 난류에 의하여 반사도에 의한 온도상승이 직접적으로 대기온도상승과 연결되지는 않는다.

The purpose of this study is to find how the students of girls' high school understand physical education. Conclusions are as follows. 1. Most students understand that physical education is an education for the whole person who is well balanced in a body and mind. And they think that physical education is health education through physical activities. 2. Students recognize that physical education is good for the healthy growth of body and mind. 3. Students show the difference of attitude according to the physical condition and the favorite sport. 4. Students are not concerned about an interest of physical education. 5. Some studnts like the class of physical education because of mental health it brings. But others do not like it because of their physical weakness. 6. In a school life, physical education gives a positive attitude, cooperation, power of conbination and a diversion. And its role is to raise effieiency to other lasses. 7. Students point out that the quality of physical education (the teaching method and contents)should be improved. 8. Students say that the dificiency of equipment checks the efficient physical education. 9. Students say that the possession of equipment does not fulfill. 10. Most students like to have physical education lesson on Saturday, Wednesday and Monday. 11. Students like to have physical education in the afternoon than in the morning. 12. Students want to learn tennis and swimming. But they can't learn it because there is no equipment in the school.
