女高生의 體力에 關한 比較硏究 : Seoul and Kang Reung district 서울과 江陵地方을 中心으로
柳明秀 관동대학교 1978 關大論文集 Vol.6 No.1
In order to compare the physical strength of high school girl students in Seoul district with that in Kang Reng district, 240 students were chosen out of four girls high schools, two in Seoul and the others in Kang Reung, by means of random sampling. All of them underwent both health inspections and physical strength. Following results were reached through their comparison. 1. Health Inspection 1) Stature Students in Seoul are taller than those in Kong Reung by 1.71 centimeter. 2) Weight Students in Seoul are heavier than those in Kang Reung by 1.54 kilogram. 3) Circumference of the Chest Students in Kang Reung are bigger than those in Seoul by 2.36 centimeters. 2. Physical Strength 1) 100meter Sprint Students in Kang Reung are 1.11 second faster than those in Seoul. 2) Long Jumping Students in Kang Reung jumped 4.25 centimeters farther than those in Seoul. 3) Hand Grenade Throwing. Students in Kang Reung threw 2.17 centimeters farther than those in Seoul. 4) Flexion of the Upper Part of Eody Students in Kang Reung were found better than those in Seoul by 1.45 centimeter. 5) Shuttle Run Students in Seoul were faster than those in Kang Reung by 0.21 second. 6) 800meter Run Students in Kang Reung were faster than those in Seoul by six seconds. 7) Sit-ups Students in Kang Reung were found better than those in Seoul by 1.28 times 8) Arm-hanging Students in Kang Reung showed better records than those in Seoul by 5.84 seconds.

In this paper, we propose a dynamic code allocation strategy using voice activity detection and evaluate the performance of a dynamic code allocation strategy using voice activeity detection in DS-CDMA system. Proposed method allocates code to mobile terminal according to the residual capacity computed by SIR in the base station. In hot spot traffic loading cell, we find that the performance of proposed method is better than that of a fixed code assignment strategy using voice activity detection. Also, we find that the proposed method provide much improvement in blocking probability against the dynamic code assignment strategy withoug voice activity detection.

The Vertical Jump Reaction Time(VJRT) has been studied by manyauthors. However, a study on the VJRT demanding jumping height seldom has made. The purpose of this study is analyze and compare for VJRT demanding 20cm, 40cm and 60cm jumping height on atheletes and non-atheletes student group in college. The subjects were divided four group ; 17 soccer players, 38 male students in physical education department, 34 male non-atheletes, and 30 female non-atheletes. The total subjects were 119 students. The Whole Body Reaction Time Measuring Apparatus(T.K.K.-1264-1) was used for this experiment. The results were as follows ; 1. The VJRT was increased according to the jumping height in each subject group. Therefore, considerations should be made in setting up for measuring the VJRT. 2. Soccer players group was proved to have been faster than male physical education department students group in VJRT and 20cm-VJRT. Male physical education department students group was proved to have been faster than male non-athletes group in 20cm-VJRT, 40cm-VJRT and 60cm-VJRT. Male non-atheletes group was proved to have been faster than female non-atheletes in VJRT, 20cm-VJRT, 40cm VJRT and 60cm-VJRT. 3.The correlations between VJRT and 20cm-VJRT, 40cm-VJRT, 60cm-VJRT in each group were comparatively positive middle coeficient.

The purpose of this study was to examine effects of leisure satisfactions and on the life satisfaction, among elderly. Data were collected form five hundred and fifty-one male and female elderly who resided in Seoul, by the method of stratified cluster random sampling. Statistics employed in the study were correlation analysis and multiple regression analysis. The major findings of this study were as follow; first, subfactors of leisure satisfaction such as psychological, sociological, and physiological satisfaction with leisure influenced on past life satisfaction among elderly. second, subfactors of leisure satisfaction such as psychological, educational and sociological satisfaction with leisure influenced on present life satisfaction among elderly. third, subfactors of leisure satisfaction such as psychological, educational, sociological, and relaxational satisfaction with leisure influenced on future life satisfaction among elderly. fourth, subfactors of leisure satisfaction such as psychological, educational, and sociological satisfaction with leisure influenced on total life satisfaction among elderly.
LDAPS 예측 강우를 활용한 한탄강홍수조절댐 홍수 유입량 예측

최근 우리나라는 지구 온난화에 의한 기후 변화로 지역별 기후 변동뿐만 아니라 극한 기상 발생의 규모와 빈도가 커지고 있다. 2013년 장마 전선이 주로 중부지방에 위치하여 중부지방에서 강수일수 최고값을 기록하였으며, 남부지방은 강수일수 최저값을 기록하였다. 이러한 강우의 공간적, 시간적 집중 현상으로 호우 피해가 발생하여 치수의 중요성이 부각되고 있다. 본 연구에서는 홍수기 신속한 홍수 방재를 위하여 예측 강우 자료를 활용하고자 한다. 이를 위해 수치 예보 자료의 적용 가능성을 지상 관측 강우 및 유입량을 이용하여 분석하였다. 지상 관측 강우와 정량적 비교를 위해 상관계수, 최대 강우강도 퍼센트 오차 및 총 강우량 퍼센트 오차 등을 이용하였으며, 유입량은 상관계수, Nash-Sutcliffe 효율계수, 표준화된 RMSE를 사용하였다. 모의 결과 6시간까지의 상관계수는 0.7 이상으로 높은 상관성을 나타내었으며, Nash-Sutcliffe 효율계수는 6시간까지 양수를 나타내어 예측 강우의 활용 가능성을 확인할 수 있었다. Due to climate changes accelerated by global warming, South Korea has experienced regional climate variations as well as increasing severities and frequencies of extreme weather. The precipitation in South Korea during the summer season in 2013 was concentrated mainly in the central region; the maximum number of rainy days were recorded in the central region while the southern region had the minimum number of rainy days. As a result, much attention has been paid to the importance of flood control due to damage caused by spatiotemporal intensive rainfalls. In this study, forecast rainfall data was used for rapid responses to prevent disasters during flood seasons. For this purpose, the applicability of numerical weather forecast data was analyzed using the ground observation rainfall and inflow rate. Correlation coefficient, maximum rainfall intensity percent error and total rainfall percent error were used for the quantitative comparison of ground observation rainfall data. In addition, correlation coefficient, Nash-Sutcliffe efficiency coefficient, and standardized RMSE were used for the quantitative comparison of inflow rate. As a result of the simulation, the correlation coefficient up to six hours was 0.7 or higher, indicating a high correlation. Furthermore, the Nash-Sutcliffe efficiency coefficient was positive until six hours, confirming the applicability of forecast rainfall.
