본 시험은 유기인계 살충제인 Terracur P입제 및 Lebaycid 입제와 유기염소계 살충제인 상감마입제$(\gamma-BHC 입제)$를 수면시용 하였을때 수도요해충인 이화명충, 끝 동매미충, 애멸구 및 흰둥멸구에 대한 동시방제가능성과 방제적기를 구명하고 약제간의 방제효과를 비교코저 실시하였다. 얻어진 시험결과는 다음과 같다. 1) 약제처리후 부화직후 이화명충 접종 시험에 있어서 상감마와 Terracur P는 높은 살충율을 보였으나 Lebaycid의 살충율은 낮았다. 約 $50\%$ 살충력 잔효일수에 있어서 상감마는 8-14日이었고 Terracur P는 6일간이었다. 2) 당초 계획된 방제적기에 관한 정보는 얻을 수 없었다. 즉 주어진 일간격이 좁아 유의한 차를 얻을 수 없었다. 3) 1,2화기 이화명충에 대한 방제효과는 Terracur P=상감마>Lebaycid의 순이었다. 4) Terracur P와 Lebaycid 입제의 처리는 끝동매미충의 방제효과가 좋았으나 상감마$(\gamma-BHC 입제)$의 방제효과는 기대할 수 없었다. 끝동매미충에 대한 Terracur P와 Lebaycid입제의 잔효력은 30일 이상이었다. 5) 애멸구와 흰등별구에 대한 시험은 충의 서식밀도가 낮기 때문에 약제간 방제효과를 얻을 수 없었다. 6) 공시약제중 Terracur P와 Lebaycidd입제는 이화명충과 끌동매미충의 동시방제제로서 사용할 수 있을 것 같다. This experiment was conducted to find out the simultaneous control effect of granulated insecticides on the several major rice insect pests in Korea. The granulated insecticides used were Terracur P$5\%$ (one of the phosphoric insecticides), Lebaycid $5\%$, and Sang-gamma (gamma-BHC) $6\%$. Those insecticides were broadcasted by hand on the paddy field at the ratio of 3kg. in June and 4kg. in August per 10 a, and the date of insecticidal application was based on the maximum moth occurrence of the rice stem borer in 1969. The rice insect pests tested in this study were rice stem borer (Chilo suppressalis W.), green rice leafhopper (Nephotettix bipunctatus cincticeps U.), smiller brown planthopper (Laodelphax striatellus F.), and white back planthopper (Sogotella furcifera H.). For the study of residual effectiveness of the insecticides, the rice stem borer larvae just hatched from the eggs were installed on the sheath of rice plants collected from the paddy field after insecticidal treatment, and the mortality was made at 48 hours after installation. High mortality was observed in Terracur P and Sang-gamma treatments and low mortality in Lebaycid treatment. The duration of residual effects giving about 50% mortality was about 14 days in Sang-gamma and about 6 days in Terracur P treatments. The study on the effectiveness of the insecticides to the rice stem borer in the paddy field was made by the number of dead blades and white heads of the rice plants injured by the larvae, and the number of survival larvae in the straws after crop harvest. The order of insecticidal effectiveness to the rice stem borer was Terracur P=Sang-gamm>Lebaycid. The study on the effectiveness of the insecticides to the leafhoppers and planthoppers in the paddy field was made by the population density by sweeping (5 times) at the given day intervals after treatments. Terracur P was highly effective for the control of the green rice leafhoppers and Lebaycid was moderately effective, but Sang-gamma seemed not to be effective. The effectiveness of the insecticides tested to the planthoppers was not clear, and it seemed to related with the low insect population density. Study on the determination of proper timing of insecticidal application was not also made clear, and it seemed to be short in the range of day intervals in the insecticidal application. For the study on the control effects of the rice insect pests, rice yield per 100 hills per plot was observed. There was no statistically significant difference among the treatments in rice yields, but the order of yield (Terracur P>Sang-gamma>Lebaycid>Control) was paralleled with the tends of control effects above mentioned. In a view point of simultaneous control of the rice stem borers and green rice leafhoppers by the application of granulated insecticides, Terracur P and Lebaycid were more effective than Sang-gamma which have been used.

The electromyographic analyses were conducted in 10 subjects during open kinetic chain exercise (OKCE) and close kinetic chain exercise(CKCE) in vastus medialis(VM), vastus lateralis(VL), and rectus femorali(RF). And the results were: 1.Both OKCE and CKCE improved the strength of quadriceps muscle as the knee joint flexion was Increased. 2.In OKCE, the strength of VM was improved the most at the 30 degree angle. 3.In CKCE, the strength of VM was improved the most at the 30 degree angle. 4.The VM/VL ratio was the largest at the 10 and 20 degree angles in OKCE and CKCE, respectively. 5.The VM/VL ratio at 10, 20, and 30 degree angles was significantly different between OKCE and CKCE (p〈.05). Base on the results, the OKCE is recommended for the knee joint patients, especially for the patellofemoral pain syndrome patients, during the early phase of rehabilitation. In order to improve strength of the quadriceps, muscle strength training at 30 degree angle is recommended. In order to improve VM/VL ratio, 10 and 20 degree angles are recommended during OKCE and CKCE, respectively. Future researches are warranted comparing electromyographic analysis between OKCE and CKCE in the quadriceps at a certain work lead, and muscle strength performance in the quadriceps at different positions of foot.

류호상,김한철 한국스포츠심리학회 2002 한국스포츠심리학회지 Vol.13 No.2

의학계의 보고에 따르면 현대생활에서 오는 각종 스트레스와 운동부족이 성인병과 함께 성활동(Sexual activity)에도 부정적인 영향을 미친다고 한다. 본 연구의 목적은 기혼남성의 생활체육 참여가 그들의 성활동에 어떤 영향을 미치는지를 조사하기 위한 것이었다. 단순무선표집물 통해 대도시에 거주하고 있는 기혼남성 530명에게 생활체육과 성활동에 대한 질문지가 배포되어 총 495명의 응답이 데이터로 사용되었다. 성활동과 유의미한 상관이 있는 것으로 나타난 연령, 소득수준, 결혼기간, 성적(性的)문제 유무를 공변인(covariate)으로 하여 공변량분석(ANCOV)을 실시한 결과 다음이 관찰되었다. 생활체육에 참여수준(p<.001), 주당참여빈도(p<.05), 운동지속시간(p<.01)은 성활동에 유의하게 영향을 미치는 것으로 나타났다. 이들 변인에 대한 사후검정(Scheffe, p<.05)을 실시한 결과, 참여수준에서 "참여하는 편이다"와"열심히 참여한다"가 "전혀 못한다"와 "못하는 편이다" 보다 높은 성활동을 나타내었다. 주당참여빈도에서도 "주4회 참여"가 "주1회 참여"보다 높은 성활동을 보였다. 운동지속시간에서는 "90-120분"이 "30분미만"과 "2시간 이상" 보다 성활동이 높은 것으로 반응하였다. 그러나 생활체육에 참여형태, 참여동반자, 참여연수, 참여종목은 성활동과 유의한 관련이 없는 것으로 나타났다. 본 연구는 생활체육 활동에 참여하여 적당히 운동을 하면 남성의 성활동에 긍정적인 영향을 미친다는 결론에 도달하였다. Medical field have reported that stressful life and lack of exercise have negative effects on adult's diseases and sexual activity. The purpose of this study was to examine the relationship between recreational sports activity and sexual activity in married males. Five hundreds thirty married males in a big city were randomly sampled and consented to participate. Data(N=495) were collected using the 25-items, self-report Sport Activity Questionnaire and the Sexual Activity Survey, developed and piloted by authors. Results of Analysis of Covariance showed that whether or not you participate in sports activity was significantly associated with the sexual activity(p<.001). Scheffe's post hoc test showed that the sexual activity was the highest in the most active participants. The frequency of sport activities(p<.05) and the duration of sport activities(p<.01) were also related to the sexual activity. The 4 times a week participation was higher than the once a week in the sexual activity(p<.05). And the sexual activities were higher in the 90 ∼ 120 min compared to the less than 30 min and more than the 2 hour exercise(p<.05). However, the participation years, the mode of sport activity, the company existence, and the regular/organized participation in sports activity were shown to have no effect on the sexual activity. It was concluded that the moderate sports activity was positively associated with sexual activity among married males.
