A anatomical Analysis of Knee joint injuries in Dancers

무용수에 나타나는 무릎관?煊? 대한 상해를 알아보고 training과정에서 일어나는 상해의 요인과 결과를 관계되는 문헌을 통하여 조사한바 무용을 실시함에 있어 무리한 technic 시도와 옳지못한 무용연습환경, 또한 상해 발생시 적절한 조치를 취하지 못함이 무릎관절 상해의 요인이라는 결론에 도달하였다.The purpose of this study was anatomical analysis of Knee joint injuries in dancers by review. The Knee joint anatomcal factors, and the causes of injuries were reviewed Findings were as follows. 1. Knee joint injuries were due to faulty technique and incorrect assistant environment when dancers do plies, jump, squant position (grand plies) pirouette, tour en l'air, Rond de jambe en l'air 2. The Knee joint injuries come up poor practice and training on quadriceps and Hamstring. 3. Chronic Knee joint injuries were due not to accept doctor's diagnosis and prescription.

A Study on the changes of physical Fithess during progressive Body weight Reduction in Wrestlers.

레슬링선수의 체중 감량시의 체력변화를 4%, 6%의 감량 후의 악력, 완력, 각력, 배근력, 사이드스텝, 윗몸일으키기, 체전굴, 500m달리기의 체력변화 측정을 한 결과 4%, 6%감량까지의 체력변화는 각 요소별로 다소의 차이는 있으나 큰 변화를 나타내고 있지 않다는 결론이 나왔다.The results were summerized as follows : 1. In case of Arm Strength and Grip strength were increased with 4% body weight reduction, but others were decreased with 6% body weight reduction. 2. In case of Leg strength were increased with 2% body weight reduction, but others were decreased with 4%, 6% body weight reduction. 3. In case of Back muscular strength were sustained normal condition with 2% body weight reduction, but others were decreased with 4%, 6% body weight reduction. 4. In case of vertical Jump an Side-steps were increased with 2% body weight reduction, but others were decreased 4%, 6% body weight reduction. 5. In case of sit-ups were increased with 2% and 4% body weight reduction but others were decreased with 6% body weight reduction. 6. In case of Forward trunk flexion were increased with body weight reduction. 7. In case of 50m dash were as good result with 2%, 4% body weight reduction but others were recorded as low result 5% body weight reduction.The results were summerized as follows : 1.

Tectonic structure of Dokdo and adjacent area in the northeastern part of the Ulleung Basin of the East Sea using geophysical data

The northeastern part of the Ulleung Basin in the East Sea is composed of volcanic islands (Ulleungdo and Dokdo), seamounts (the Anyongbok Seamount, the Simheungtaek and the Isabu Tablemounts), and a deep pathway (Korea Gap). To understand tectonic structure and geophysical characteristics of Dokdo and adjacent area, We analysed geophysical potential data of KORDI(Korea Ocean Research and Development Institute), KIGAM(Korea Institute of Geoscience and Mineral Resources), and NORI(National Oceanographic Research Institute of Korea) around the Dokdo volcanic body except Ulleung Do because of empty data of its large island. Also, we eliminate the effect of water and sediments from the free-air gravity data to process 3D Moho depth inversion. 3D tectonic structure modelling of the study area was developed using Moho depth inversion result and sediment thickness data of NGDC(National Geophysical Data Center). The free-air gravity anomalies of the study area generally reflect bathymetric effects. Although the Dokdo seamounts have a similar topographic size, the decrease of free-air anomaly toward Isabu suggest that Isabu is oldest among the seaounts and have high degree of isostatic compensation. High Bouguer anomalies in the central part of the Ulleung Basin gradually decreases toward the Oki Bank. This feature suggests that the crust/mantle boundary is shallow in the central part of the Ulleung Basin. The complex magnetic pattern of Dokdo suggests that it might have erupted several times during its formation. The magnetic anomaly amplitude of Isabu is much smaller than that of Dokdo. Such low magnetic anomalies are attributed to a secondary change caused by the metamorphism or weathering of ferromagnetic minerals of the seamount during a long period of time after its formation. Analytic signals show high anomalous zones over volcanoes. Also, there are high analytic signal values in Korea Gap indicating magmatic intrusion in thick sediments. The power spectrum analysis o1
