  • The purpose of this study was to evaluate the kinematic characteristics of 5th hurdle clearance during the 100m hurdle final competition at the 2010 Colorful DaeGu pre-championship meeting. This study was also intended to provide the technical data for better performance for preparing the 2011 world championship. Lee and Jung need to change technical movement by reducing the distance of the take-off point from the hurdle and by decreasing the vertical velocity of the C.G.(center of gravity) at the takeoff. Powell's angle of the take-off leg showed bigger at the touchdown and smaller at the takeoff comparing to Lee's and Jung's. Furthermore, Powell's horizontal velocity of the C.G. was maintained at the takeoff and touchdown. So, Lee and Jung need to change angle of the take-off leg the same as Powell's. Both Lee and Jung need to increase the angle of landing leg at the touchdown. In addition to increasing the angle Jung needs to improve the knee and ankle velocity with the hurdling leg.

  • Purpose To investigate the impact of Nosa Ki Jung-jin on the development of Sasang Constitutional Medicine by Dongmu Lee Je-ma. Objectives and Methods To establish the correlation between Nosa and Dongmu through an analysis of 『Nosajip(蘆沙集)』 and 『Nosaseonsaengyeonwonrok(盧沙先生淵源錄)』. Conclusion 1. While it is not definitive to assert that Lee Mupyeong, referenced in the 'SongLeemupyeongBukgwiseo(送李務平北歸序)' of 『Nosajip』, is Dongmu, there exists a strong probability that he is indeed Dongmu. 2. Dongmu Lee Je-ma's name does not appear among the disciples listed in 『Nosaseonsaengyeonwonrok』, and the 'SongLeemupyeongBukgwiseo' is only found in the third edition of 『Nosajip』. 3. It is challenging to attribute Dongmu's development of Sasang Constitutional Medicine solely to his exposure to Nosa's teachings during his youth.
