R. J. SUNG. Mathcad program as a useful tool for the teaching and studying the sport biomechanics. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 301-311, 2004. The purpose of this study was to verify the usefulness of the Mathcad program as a tool for the studying and teaching the sport biomechanics. A projectile motion was analyzed because it is the one of the most popular motion in sports activities. A 3 dimensional CG data for the high jump bar clear phase was used to calculate the initial velocity vector of the CG. Linear regression function and other functions such as cubic spline and derivative of Mathcad were used to calculate this vector. Finally, the approach angle to the bar and peak jump height was calculated. Programming in Mathcad was relatively easy compare to traditional computer language such as Fortran and C, because of the unique documentation method of Mathcad. Additionally the 2 and 3 dimensional graph function was very easy and useful to describe the mechanical data. If the use of Mathcad program is more popular in the field of sport biomechanics, it could greatly contribute to overcome the limit of research caused by the lack of proper programming ability.

성준경,윤화영 동국대학교 대학원 2001 東院論集 Vol.14 No.-

Since the Statement of Forest Principles and Agenda 21 in 1992, sustainable forest management(SFM) has become a main subject for forest management in the world. For achievement of SFM, criterion and indicator(C&I) are essential factors. The Montreal Process was formed in Geneva, Switzerland, in June 1994 to develop and implement internationally agreed criteria and indicators for the conservation and sustainable management of temperate and boreal forests. At the 6th meeting of the Montreal Process Working Group in Santiago, Chile, in 1995. And then, the 10 member countries endorsed a statement of political commitment known as the "Santiago Declaration" which included a comprehensive framework of 7 criteria and 67 indicators. Among the these C&I, the criterion 7 is an effective legal and institutional framework. The first indicators of criterion 7 is the legal framework(laws, regulations, guidelines), including the 5 assessment extent, to support sustainable forest management. A purpose of this study is the assessment of criterion 7, especially the legal framework, for SFM in the Korean Forest Law. As a results of this study, the korean forest law is relatively well organized for SFM. But the indicator 7.1.b which is the legal framework to provide opportunities for public participation in public policy and decision-making related to forests and public access to information will have to develop and improve for SFM.

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.
