Hand-Jumbo vault which is the most frequently performed in women`s vaulting event was analyzed in this study. For the purpose of this study three Korea national gymnasts were participated to collect 3D video-graphical data. Two video cameras were used and the range pole survey method was applied to compute spatial coordinates of subject motion. From the analysis the following results were obtained: 1. The subjects showed the largest time during the postflight phase which is about 60% of total time duration. 2. The take off angle from the board was about 40 degree and there was a little difference which might be critical effect on the vaulting performance from technical viewpoint. 3. The subjects, S1 and S2 tended to have the lower vertical preflight displacement, which could not have enough momentum for the following movements. 4. The specialists in gymnastics postulated that the most important factors in Hand-Jumbo vault were the board contacting variables because they could decide the whole phase of motions especially for the elite gymnasts.

Uterine rupture is the important cause of life threatening to mother and fetus, in spite of progressed obstetrics. We must observe the patient carefully before labor, during labor and after delivery for the higher prediction of uterine rupture. We experienced a case of incomplete uterine rupture at 40 weeks of gestation weeks in a 37-year-old multigravida tried vaginal birth after cesarean delivery. So we present it with brief review of literatures.

Yang, D-Y. The Analysis of the transfer of angular momentum on upper extremity during Fee Throw Motion in Basketball. Korean Journal of Sport Biomechanics, Vol. 13, No. 1, 185-204 The purpose of this study was to obtain the data stable and accurate techniques of the free throw in basketball. The subjects of this study were seven male basketball player consisted of college students athletes. Free throw motions were taken by video camera. the three-dimensional coordinates was processed by DLT. The variables were the velocity, the angular velocity of the upper extremity segments, degree, and angular momentum. The result of analysis in summarized as follows. 1. The velocity and angular velocity of the upper extremity segment was showed an gradual increase and a smooth velocity transfer, transferring from proximal segment to distal segment at free throw motion in basketball. 2. The local term and remote term angular velocity momentum of the proximal segment showed larger than that of the distal segment in X, Y, Z axis component all. 3. The remote term angular momentum was showed larger than that of the local term angular momentum in X, Y, Z axis component all. 4. The angular motion of the upper trunk and upper arm, upper arm and forearm was showed in opposite direction and symmetrical angular momentum in local term angylar momentum of the Y and Z axis component. 5. All the segments of upper extremity segment was showed left rotation in remote term angular momentum of the Y axis component and right rotation in remote term angular momentum of the Z axis component.

오르막 슬로프에서 크로스컨트리 스키의 V1 스케이팅 주법에 대한 운동학적 분석
김갑선,양동영 한국운동역학회 1997 한국운동역학회지 Vol.7 No.1
The aims of this study are as follows; first, to find out the difference between successful skier group and the unsuccessful group by comparing and analyzing the skating technique action of cross-country skiers who use V1 skating technique in uphill slope. Second, to present effective skating motion through analyzing various kinematic variables, such as trunk angle, arm angle, knee angle, ski pole, ski angle, in uphill course. The subjects of this study are made of two successful male skiers of national level and three unsuccessful male skiers of nonnational level. The motion performed by subjects were recorded using two video cameras at the speed of 60 fields per second, and analyzed using the DLT(Direct Linear Transformation) method of three dimentional cinematography. The conclusions are as follows; 1. In order to increase the skating velocity, it is needed to lift waist near vertically when begin poling, and stoop the upper body forward when gliding, out of consideration that the successful group has the wider motion scope of trunk angle than the unsuccessful group. 2. To increase a propulsive force, hands has to be held out to the motion direction, and ski poles are needed to be planted on the snow leaning to the body center direction. 3. For a strong skating force, it is necessary that knees, which have an effect on the cycle length, are bent much at the beginning of skating phases. And then, at the end of skating phases, it is needed to straighten the knees full to the outside of snow, and then to kick. 4. As for ski angle, skiers has to provide a strong propulsive force to the gliding ski, by kicking to side, decreasing the ski angle concerning course direction.

The purpose of this study was to analyze kinematically the Golf swing motion. For the purpose of this 10 subjects were employed in this study. Among the subjects, five of them were skilled golfers with single handicapped and the rest of them were unskilled players with about 1 year of experience. They are all right handed. The subjects were asked to do golf swing with three different clubs, PW, 5-iron, and Driver. The motions were filmed using 4 Panasonic D5100 video cameras and AMTI force plate was used to collect ground reaction forces during the swing motion at 50Hz. Each subject made five swing motion and two of them were selected for analysis. The results obtained from the study were as follows; 1. Looking at the general patterns of golf swing, unskilled golfers showed shorter follow through, which could have influence the distance of the ball 2. The movements of body segments in skilled golfers tended to be more effective than those in unskilled golfers. Especially the movements of elbow joint is quite different from each other. 3. Based upon the data of center of pressure of the subjects, skilled golfers showed more reliable and balanced distribution than that of unskilled golfers. There were also significant differences among the lengths of golf clubs, i.e., short iron, middle iron and driver. 4. The subjects displayed the significant difference in the length of center of pressure and area of center of pressure between groups and clubs. The longer the clubs are the larger the values are. Also, skilled golfers had smaller measurements.
