The purpose of this study was to investigate the changes of coping response for each point of time of a competition according to a performance level and gender. 154 high school table tennis players(male 81, female 73, superior 43, inferior 111) who participated in 20th President Flag table tennis tournament were selected for this study and KASCS(Korean Athlete Sport Coping Scale) questionnaires were used to measure problem focused, emotional focused, detached, avoidance coping factor. The results were as followings. 1. The change of coping response according to a performance level and the point of time of a competition statistically showed each significant difference by performance level, the point of time of a competition, interaction effect of a performance level and the point of time of a competition in problem focused coping factor and detached coping factor. Superior plays were higher than inferior players in problem and detached coping factor. 2. The change of coping response according to gender and the point of time of a competition statistically showed each significant difference by gander and the point of time of a competition in problem focused coping factor and emotional focused coping factor, and in terms of avoidance coping factor there was a statistical significant difference by the point of time of a competition Male players were higher than female players in problem and emotional coping factor.

The aim of this study was to determine whether gait training using powered gait orthosis (PGO) improved gait function in paraplegics following spinal cord injury (SCI) and whether it suppressed related complications. Three complete SCI patients were used as case studies and put through four months of the gait training. The parameters of gait function—namely, velocity, step length, and cadence—were evaluated by three-dimensional motion analysis. The body fat mass (BFM) and the bone mineral density (BMD) of the femur were also measured. Velocity, cadence and step length were observed to significantly improve (p = 0.026, 0.039, 0.013, respectively)after four months of PGO gait training; furthermore, there were increments in all the subjects. BFM also significantly decreased (p = 0.004), but there was no significant change in body weight (p = 0.072), although a decrease was observed in all the subjects. Moreover, no significant change in BMD was observed (p = 0.221), although there was an increment in all the subjects. These results showed that gait training using PGO contributed to not only improving gait function in SCI patients but also suppressing increase in body fat mass and bone loss.
