R. J. Sung. A Study on the Swing Path and Plane of the Club in Golf Swing. Korean Journal of Sport Biomechanics, Vol. 14, No. 1, pp. 99-115, 2004. In order to know the correct swing methods in golf swing, it is important to understand the whole swing path but also the concept of swing plane. But, most amateur golfers don't know the concept of swing plane well. Therefore this study was trying to make a good material that makes the concept of swing plane easy to understand. A good swing motion data was obtained from a professional golfer using the three dimensional DLT method. This swing motion was divided into 10 phases and evaluated using the concept of swing plane. The result of the analyze show a good matches between the path of the club and swing plane. This result was summarized as a 3 dimensional graphics to provide a good material to teach the golf swing well.

R. J. SUNG. Analysis of the Angular Momentum for the Bar Clearance Motion in the Fosbury Flop. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 119-134, 2004. The purpose of this study was to analyze the angular momentum characteristics of the Fosbury Flop high jump and the role of the body segments for the production of 3 angular momentum components. The subjects were three male jumpers who were former Korean national team players. Their jumping motions were analyzed using the DLT method of three-dimensional cinematography. The conclusions were as follows. 1. All the forward angular momentum needed to clear the bar was created in the take-off phase. Take-off leg was the great contributor of the forward angular momentum. On the other hand, free leg produced large opposite angular momentum. 2. All subject had some lateral angular momentum before the take-off phase. Head and free leg had major contribution to the lateral angular momentum production. Take-off leg produced opposite angular momentum. 3. All subject had some twisting angular momentum, which make the back of the athlete turn to the bar, before the take-off phase. Free leg was the major contributor of the twisting angular momentum. Head and trunk was the second contributor of the twisting angular momentum. 4. Total angular momentum needed to clear the bar had no significant correlation to the jumping height. 5. Subject who made excessive angular momentum showed different pattern of angular momentum production and had a poor record compared to other subject.

담배의 잎조직 배양에 있어서 기관형성과 동위효소 유형에 미치는 생장조절제의 영향
成淳基,金濬喆,成敏雄 慶尙大學校 1986 論文集 Vol.25 No.2
담배(N. tabacum cv. NC 2326) 잎조직 배양에서 기관형성에 가장 효과적인 생장조절제의 배지조성을 찾기위하여 NAA와 kinetin의 농도별 혼합처리 5종류 및 picloram과 BAP의 농도별 혼합처리 5종류의 배지에서 26℃ 조건으로 35일간 잎조직을 배양시켜 각 처리구에 대한 기관형성률을 조사하고, 6종류의 효소에 대한 동위효소 유형 및 단백질 함량은 기관형성이 가장 잘된 0.01㎎/l pocloram+0.6㎎/lBAP 처리구와 0.5㎎/l NAA+0.5㎎/l kinetin 처리구의 두 처리구의 배양체를 대상으로 조사한 결과는 다음과 같다. 1. NAA와 kinetin을 혼합처리한 5종류의 배지중 0.5㎎/l+0.5㎎/l kinetin 처리구에서 shoot와 뿌리가 각각 100% 및 50%로서 가장 높은 기관형성률을 나타냈다. picloram과 BAP 혼합처리구에서 callus형성률은 평균 6%로 callus 형성에는 효과적인 배지는 아니었으나 기관형성률은 높게 나타났다. 그 중 0.01㎎/l pocloram+0.5㎎/lBAP 처리구에서 shoot와 뿌리가 각각 100% 및 90%의 형성률을 나타내어 기관형성에 가장 효과적이었다. multiple shoot 형성에는 picloram과 BAP 혼합배지가 NAA와 kinetin 혼합배지보다 더욱 효과적임을 알 수 있었다. 2. 배양제의 단백질 함량은 기관형성 과정에서 배양이 진행됨에 따라 두 처리구에서 모두 감소하였으나 picloram과 BAP 혼합처리구는 NAA와 kinetin 혼합처리구보다 낮았다. peroxidase의 활성은 이와 반대로 picloram과 BAP 혼합처리구에서 약 8배 높게 나타났다. 3. peroxidase와 malate dehydrogenase 동위효소들의 활성은 shoot가 형성됨에 따라 두 처리구 모두 증가하였으나, lactate dehydrogenase 동위효소들은 두 처리구 모두 감소하였다. 이러한 경향은 두 처리구 중에서 picloram과 BAP 혼합처리구에서 더욱 뚜렷하였다. 그러나 esterase, acid phosphatase, aspartate aminotransferase 동위효소들의 활성은 shoot 형성중에 두 처리구 모두 뚜렷한 변화가 없었다. 4. 6종류의 효소에서 분리된 동위효소의 수는 두 처리구를 합쳐 peroxidase에서 12개, acid phosphatase에서 6개, aspartate aminotransferase에서 9∼13개, lactate dehydrogenase에서 3∼5개, esterase에서 10∼16개가 각각 확인되었다. Tabaco (Nicotiana tabacum cv. NC 2326) leaf tissues were cultured on Murashige and Skoog medium containing various concentrations and combinations of some growth regulators at 26℃ for 35 days. The obtained results were summarized as follow; 1. Organ formation was 100% in shoot and 50% in root on the medium containing 0.5㎎/l NAA and 0.5㎎/l kinetin. On the medium containing 0.01㎎/l picloram and 0.5㎎/l BAP, organ formation displayed 100% multiple shoot formation and 90% root formation without callus formations. Multiple shoot formations were enhanced more by picloram and BAP groups than by NAA and kinetin groups. 2. During the shoot formation, protein content in the cultures on the medium containing picloram and BAP was lower than NAA and kinetin groups, but peroxidase activity in the former medium was higher about eight times than that in the latter medium. 3. The activity of anodic peroxidase and malate dehydrogenase isozyme increased during the shoot formation, whereas that of lactate dehydrogenase isozyme decreased. However the activity of esterase, acid phosphatase, and aspartate aminotransferase did not change. 4. All the isozymes were separated with 12 bands in peroxidase, 6 in acid phosphatase, 9∼13 in malate dehydrogenase, 3∼5 in lactate dehydrogenase, 10∼16 in esterase, 6 in aspartate aminotransferase during the shoot formation.

한국에 있어서 Sustainable Forest Management에 따른 Criteria 와 Indicator의 개발에 관한 연구
성준경,윤화영 동국대학교 생명자원과학대학 연습림 2000 연습림논문집 Vol.- No.6
Since the implementing the Statement of Forest Principles and Agenda 21 in 1992, sustainable forest management(SFM) is a main subject for forest management policy in the world. In the achievement of SFM, criterion and indicators(C&I) are essential factors. Because C&I are able to monitoring, analysis for forests and these results are used to a policy decision, the data of forest investment in the future. This is the point of C&I. Therefore, the C&I are made for SFM certainly and included the dynamical factors of forest and social factors, environmental factors etc. A purpose of this study is C&I development for SFM in Korea. This study presents 6 criterion and 44 indicators. These C&I are included the forest health, multiple benefits of forests to society and the accepting society's for SFM. This study is experimental research. Therefore, these C&I are able to supplement and change.

습지는 한번 훼손되면 재생 불가능하고 그 대체물을 만들 수 없으므로 습지보전과 대책마련이 증요하다. 최근, 환경단체에서 자연습지 뿐만 아니라 산지습지에 대한 지속적인 생태적 조사와 발견이 중요하다는 인식이 높아지고 있다. 본 연구에서는 산지습원에 대한 기준점 측량방식으로 Total-Station과 GPS (Global Positioning System) 측량장비를 이용하여 정확한 위치를 규정하였고 지리정보(GIS) 기술을 활용하여 체계적으로 자료를 관리할 수 있는 표준화된 습지분포 수치지도를 제작하였다. 또한,복잡한 지도l 설계도면과 종합적 자료관리와 의사결 정 과정을 지원하기 위한 자료를 수치화 하였다.
