ABSTRACT
According to the techniques used by judoists in 1996 Atlanta Olympic Games and 1997 Judo Word Cup. Haraigoshi was one of most used techniques by different levels of judoist to win the game. However, although its basic skill does not change, the different movements will be developed according to the judoists body type, experiences, native intelligence, and coaching style. For this reason, the purpose of this study is to investigate the kinetics and kinematics differences when the position of support leg of thrower were at 60 degrees, 90 degrees, and 120 degrees with thrown.
Eight judoists participated in this study. Two JVC 9800 digital cameras（60Hz） and one Kistler 9287（600Hz）force platform were used to collect the kinematic and kinetic data..
The results of this study were as followed:
1. The greater the support leg angles, the shorter the movement time.
2. No difference was found on thrown maximum center of gravity（C.G）velocity and thrower maximum C.G vertical displacement and maximum attack leg C.G velocity on different support leg angles.
3. The minimum angles of knee joint and the minimum body angle had significant difference between support leg at 90 degrees and 60 degrees.
4. Maximum vertical ground reaction force（GRF）of thrower was observed near 0.1 second after thrown both feet off ground. No difference on maximum GRF was found on three angles.
5. This study showed that the angle 90 degrees was the best angle between three position.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

ABSTRACT
The objective of this study is to compare the performance by eight elite badminton male players（ages; 18.4±0.5years，height;174.1±4.6cm，weight; 67.3±4.2kg） from Taiwan senior high school who finished third in the 2000th academic year National High school Athletic Meet. Two Red Lake high-speed video cameras operating at 250Hz were used to record the subjects when they were executing the smash and jump smash stroke actions. The cameras were set up to record the movements of the upper limbs in the sagittal plane. In this study, we have analyzed the motions with Motus and SAS 8.02ver software. A t-test was used to evaluate the correlation for the execution of jump smash and smash with the selected relevant biomechanical parameters. The selected parameters were test at 0.05 significant levels. The results showed that:
1.A significant correlation（p<0.05）is indicated between the flight angles for jump smash and smash. The average shuttlecocks flight angles for jump smash at -15.7±3.5° is much greater than that for smash at an average of -7.1±3.4°.
2.The contact point of jump smash （2.82±0.08m）is higher than smash（2.44±0.05m）.
3.The following biomechanical variables also indicated a more significant change during the execution of jump smash in comparing with smash:
(a) The distance between the lowest point of center of mass (COM) to minimum height of COM just before the instance of making contact with the shuttle.
(b) The minimum height of the COM comparing with the player’s height
(c) The heights of the COM before and during making contact with the shuttle and the elevation of the COM in relation with the players’ heights
(d) The lateral distance between backward and forward movements, the time rate of change of the location of COM and the total time for motion execution
The reason is due to the prior action of squatting of the body before jump while executing the former stroke action.
4.The distance of contact point to COM, the horizontal distance and the average angle between upper limb’s joints showed no appreciable deviation during the motions of jump smash and smash. The analysis showed consistency in the stroke motion for the high school badminton players while executing either the jump smash or smash actions.
5.While executing the two stroke actions, the senior high school badminton players showed a larger extension of the upper arm and a sharper angle at the elbow joint. The players also showed accelerated wrist angle velocity at contact and a distinct flexing of the wrist is clearly visible. The combined actions resulted in an accelerated shuttle initial speed.
