In this paper, we propose a new method of converting 2D video into 3D stereoscopic video, called stereoscopic conversion. In general, stereoscopic images are produced using the motion informations. However unreliable motion informations obtained especially from block-based motion estimation cause the wrong generation of stereoscopic images. To solve for this problem, we propose a stereoscopic conversion method based upon the utilization of key frame that has the better accuracy of estimated motion informations. As well, as generation scheme of stereoscopic images associated with the motion type of each key frame is proposed. For the performance evaluation of our proposed method, we apply it to five test images and measure the accuracy of key frame-based stereoscopic conversion. Experimental results show that our proposed method has the accuracy more than about 90 percent in terms of the detection ratio of key frames.

This study purpose is to improve athletes by investigating the relation between the leadership behavior type of athletes and athlete satisfaction and exercise flow. The sampling method was non-probabilistic sampling method. The number of questionnaires was 381 for analyzing the data. SPSS/PC+ Window 21.0 version statistical program were used for analyzing the questionnaire answers. Frequency analysis, factor analysis, correlation analysis and multiple regression analysis were used. The study results are as follows. First, there were positive correlations between leadership behavior type of athletes and athlete satisfaction and exercise flow, but not between authoritative behavior of leader behavior type and exercise flow. Second, the effect of leadership behavior type of athletes on satisfaction of athletes was positive on social interaction related with training, instruction, and social support, on task execution related with training and instruction, and on coaching related with training, instruction, and positive feedback. Third, the effect of leadership behavior type of athletes on flow of exercise was positive on cognitive commitment related with training, instructions and positive feedback, and on behavioral commitment related with training, instructions, positive feedback, and social interaction. So, athletes will be able to perform good exercise skills if they come to the game in flowing exercise satisfaction and exercise.

This study was performed to observe the responses of angiogenesis-related protein expression in skeletal muscle of aged rats by regular resistance exercise training with aerobic exercise. For the purpose of the study, naturally aged SD rats (20-24 months, N=18) were used and divided into control (CON, n=6), resistance exercise (RE, n=6), and resistance + aerobic exercise (RE + AE, n=6) groups. RE group performed 3 sets × 4 exercises each session using a ladder for laboratory animals, and RE +AE group performed 2 sets × 3 times of ladder climbing and additional treadmill running (30 min) each session. After 8 weeks of exercise training, soleus muscle and extensor digitorum longus muscle (EDL) were extracted and used for analysis. Western blot was performed to analyze the expression levels of angiogenesis-related proteins (HIF-1α, VEGF, FLK-1, Ang-1, Ang-2) in skeletal muscle. As a result of the study, the expression of HIF-1α, VEGF, FLK-1, Ang-1, and Ang-2 proteins in soleus muscle (type I muscle) was higher in RE +AE than in CON group, and HIF-1α, VEGF, Ang-1, Ang-2 protein expression of RE group was higher than that of CON group. Furthermore, Ang-2 to Ang-1 ratio of RE + AE group was higher than that of RE group, showing differences by exercise type. In EDL muscle (type II muscle), HIF-1α was increased only by RE group, whereas VEGF and FLK-1 protein expressions were increased in both training types, and no difference was observed between the types of exercise training. In addition, there was no difference in angiopoieitin protein expressions in EDL muscle by exercise training. Therefore, in aging, regular exercise training induces skeletal muscle angiogenic response regardless of exercise type, and in particular, the combination of aerobic exercise with resistance exercise may have an additional positive effect on angiogenesis in type I muscle.

This study was to examined the effect of chain types exercise of lower limbs on the motor performance differences for the life-carement. For this, twenty normal adult women participated and they were examined the differences of exercise effects about abdominal muscle activity and balance ability by applying two types of chain exercise. In order to identify the differences we let them conduct exercise for 4 weeks with each type of exercise. And we used paired t-test and Independent sample t-test for comparing the differences in the group and inter groups. There was a significant difference in the value of 0.05 to verify statistical significance. As a result of this research, it was found that closed chain exercise is more effective than open chain exercise in muscle activity and balance function. Therefore, in the clinical therapeutic environment, if you apply chain exercise for patient to improve lower limb motor performance, we would recommend the close kinematic chain exercise.
