최승윤,배상희,송유한,Choi Seung Yoon,Bae Sang Hee,Song Yoo Han 한국응용곤충학회 1970 한국식물보호학회지 Vol.9 No.1

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 purpose of this study is to find out the study of the effective field experience learning method through the geological survey of the Amnam Park. The field experience learning has been used in the general subjects and in that case data supply is common. But the data supply is lack in the programs of the earth science especially in Busan , it is rare to learn geological matters with topography of Busan. With the results of this study it is possible to maximize the learning effect by using the outdoor environments. The Amnam Park which is accessible to students with convenient transportations has the effective stratum outcrops for the different rocks, faults, folds, intrusion of magma, metamorphic-contact transformation rocks what show the various lithosphere change phenomenon and the lithosphere leveling. With the results of the concentrative survey of the Amnam Park, this study proposes the localization of the text of the local environment of nature, application and shows the way of the teaching and learning effects. As the results are as follows. First the Amnam Park specifies the geological history of Busan observing the stratum outcrops of that place which was consist of terrestrial deposit(accumulative layer) in the Lake or swamp environments. Second the Amnam Park shows the topographical characteristics formed by the lithosphere leveling and the movement of seawater and various topographical facts for example weathering, erosions, coast terrace, erosion by seawater caves. Third the Park has the variety of the stratum outcrops and evidences of lithosphere transformation relatively in the Small space. It has the advantage for the worthy geological learning place owing to accessible location. Using the field experience learning relating the geological unit in the Elementary School has effective learning for the students. The field experience learning with the text of localization provides the students with the love for their own place and the spirit for the preservation of nature as the accessory effects.

To evaluate the effectiveness of Arctii Fructus(AF) in the treatment of allergy, studies were done experimentally. The results were obtained as follows : 1. Cytotoxicity of AF extract on the mouse lung fibroblast cells was not shown below the level of 100 ㎍/㎖ concentration. 2. In the quantification of IL-1β gene development, the amount was decreased compared to control group, gut which was insignificant. 3. Gene development of IL-4 was suppressed over 70% in the concentration of 100㎍/㎖ and also the of production of IL-4 was decreased significantly in the concentration of 100㎍/㎖ compared to the control group. 4. Gene development of Il-5 was decreased to 60% in the concentration of 100 ㎍/㎖ compared to the control group. 5. Gene development of IL-4 and IL-10 were decreased compared to the control group, but which was not significant. 6. Gene development of TNF-α was suppressed over 60% in the concentration of 10 ㎍/㎖ compared to the control group. 7. The effect of suppression of IgE production was significantly decreased in the concentration of 100㎍/㎖. 8. The effect of suppression of Histamine release was decreased significantly in the concentration of 100 ㎍/㎖. According to the above results, AF has antiallergic effects and suppression of the immune response. Thus it is suggested that aqua extract of AF could be applied to the aqua-acupuncture for suppressing humoral immune response, and further research is recommended.

Recent advances in both the diagnosis and treatment of hepatocellular carcinoma have improved the prognosis and changed the clinical significance of the recently increasing distant metastases. Distant metastases found after successful treament of the primary lesions are of great clinical significance for the treatment of hepatocellular carcinoma. The duodenum is a rare site of hematogenous metastases or direct invasion from hepatocellular carcinoma. A 23 year old man was admitted with upper gastrointestinal bleeding. He had been diagnosed with hepatocellular carcinoma and treated by a left lobectomy and chemoembolization. The patient was admittted for 12 months after the treatment of the primary tumor. Endoscopic examination revealed a mass in the duodenal bulb that protruded into the lumen. He died due to massive hematemesis. We report on a rare case of hepatocellular carcinoma with duodenal invasion in a 23-year-old male patient.

The aim of this study was to evaluate exposure to dust and endotoxin produced while working at swine confinement buildings. The dusts and endotoxin may cause adverse health effects on humans. Fourteen swine farms located at Yong-In, I-Cheon and Yeo-Ju of onggi-do were investigated. Husbandry workers form the farms were requested to wear personal sampler to measure respirable dust levels. Area samplings for total and respirable dust were also conducted at swine confinements buildings by season (summer under window open, winter under window close.) Gravimetric analyses and Limulus Amebocyte Lysate assay for measu- rement of dust level and endotoxin, respectively. The highest geometric mean (GM) concentration of airbome dusts was 7.47mg/㎡ for area respirable dust. and 10.35mg/㎡ for personal respirable dust. For respirable dust levels, seven farmers exceeded level of ACGIH, 3mg/㎥. The highest GM of endo- toxin was 5745.40 EU/㎥ for personal respirable dust. Significantly increased level of total dust (p〈0.001) and endotoxin in area total dust was observe with winter samples compared with those of summer. Area total dust and area respirable dust (r-0.622, p〈0.0001) was very significantly correlated in winter. Swine husbandry worker may have a considerable risk of ill health whenexposed to level of dust or endotoxin demonstrated at this study.

류호상,현정희,변재철,김한철 한국스포츠심리학회 2002 한국스포츠심리학회지 Vol.13 No.3

최근 10여년 동안 운동과학에 대한 다량의 문헌들에도 불구하고 여성들을 대상으로 운동지속(exercise adherence)과 운동효과에 대한 연구들은 많지 않다. 이 연구의 목적은 강화방법이 여성의 운동지속과 건강에 미치는 영향을 규명하기 위한 것이었다. 생활체육으로 에어로빅댄스를 하고자 방문한 31명의 중년여성들이 자신들이 원하는 세 개의 다론 시간대의 수업에 각각 등록을 하였다. 각 교실은 체지방 측정치로 피드백을 제공받는 집단(n=10), 출석이 양호할 시 에어로빅무용복을 보상받는 집단(n=11), 그리고 통제 집단(n=10)이 되어 실험에 참가하였다. 피험자들을 같은 강사의 지도로 하루에 45분, 주 5회(월-금), 8주 동안 에어로빅댄스를 실시하였다. 일원변량분석 결과 체지방으로 피드백을 제공받으며 운동한 집단은 다른 두 집단에 비해 높은 출석률을 보였다(p<.05). 공변량분석(ANCOVA)에서는 피드백 집단이 통제 집단보다 체지방율과 POMS의 총정서장애(Total mood disturbance)에서 유의하게 낮은 수치를 보였다(p<.05). 안면피부상태에서는 집단 간에 유의한 차이를 보이지 않았지만, 집단을 합한 운동 전·후간에는 차이가 있게 나타났다(p<.05). 이 연구는 생활체육 현장에서 피드백을 제공하여 강화를 시키면 중년여성들의 운동지속(exercise adherence)을 높일 수 있고 건강 증진에도 효과적이라는 결론에 도달하였다. 그 외 연구결과를 토대로 운동지속을 높이는 관점에서 논의가 이루어지고 장래연구를 위한 방향도 제시되었다. Despite decades of physical activity research, little is known about the patterns and effects of physical activity among women. The purpose of this research was to examine whether reinforcement strategy would positively influence participation adherence and health in women. Thirty one middle-aged females participating in an aerobic dance class were randomly assigned to three different conditions; feedback (n=10), reward (n=11), or control (n=10). The provide of feedback group was weekly informed of their body fat(%), while participant reward group was announced to win an aerobic dance tights if they miss less than 5 times over an 8 week period meeting 5 times per week. One-way ANOVA showed that the feedback group was higher than the other 2 groups in the number of attendances (p<.05). ANCOVA indicated that the feedback group exhibited statistically greater improvements in the body fat (p<.05) and the total mood disturbance (p<.05) than did the control. The facial skin condition was independently associated with reinforcement. However, repeated t-test showed that the after condition was better than the before condition. It was concluded that provide of feedback is an effective mean in increasing the exercise attendance rate and the health of middle-aged females. The findings were discussed in terms of the importance of increasing exercise adherence and mental health.

기혼남성의 생활체육 참여와 성활동의 관계

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.

운동형태가 청소년의 상태불안 감소에 미치는 영향

류호상,염민선,변재철,박승한 한국스포츠심리학회 2002 한국스포츠심리학회지 Vol.13 No.2

과거의 운동심리학(exorcise psychology) 문헌들은 일회(acute) 운동 후에 상태불안이 감소되어 기분이 좋아지는 효과를 얻을 수 있다고 밝혀왔다. 이 연구의 목적은 어떤 형태(유산소 대 무산소)의 일회 운동이 청소년의 상태불안과 그에 관련된 생리변인들에 보다 긍정적인 영향을 미치는 지를 비교하고자 하는 것이었다. 12명의 남자중학교 학생들을 6명씩 두 집단으로 나누어 한 집단에게는 유산소운동을 다른 집단에게는 무산소운동을 시킨 후, 1주일 후에는 서로 역할을 교대시키는 반복측정을 하였다. 유산소운동은 심박수를 이용하여 최대운동능력(VO_2peak)의 75%강도로 트레드밀에서 20분간 달리기를 하는 것이었고, 무산소운동은 5개의 웨이트트레이닝을 십회반복최대(10RM)의 75% 강도로 돌아가며 20분간 실시하는 것이었다. 각 운동 전·후에는 20분 동안 안정을 취한 뒤 상태불안, 체온, 그리고 혈압을 차례로 측정하였다. 각 운동조건의 평균을 비교하기 위한 통계분석을 사전점사 결과를 공변인으로 하고 사후점사 결과를 종속변인으로 하는 공변량분석(ANCOVA)을 실시하였다. 자료처리 결과, 유산소운동과 무산소운동 후 어떤 변인들에도 유의한 차이가 나타나지 않았다(p<.05). 따라서 청소년의 상태불안을 감소시키는 데는 운동형태간에 차이가 없으며 그러한 연구에 대해 지속적인 관심과 필요성이 강조되었다. The purpose of this study was to examine aerobic versus anaerobic exercise effect on state anxiety reduction and related physiological variables in middle school students. A total of twelve male subjects were assigned to 20-minute condition in each exercise with the intensity of 75% of VO_2peak and 75% of 10 Repetition Maximum. State anxiety(Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983), body temperature, and blood pressure were assessed 20-minute before and after each exercise. One-way analysis of covariance(ANCOVA) indicated that the self-reported state anxiety, the body temperature, and the blood pressure were not significantly different between the 2 types of exercise. In conclusion, it is too premature to state that aerobic exercise is better than anaerobic exercise on state anxiety reduction in adolescents.
