  • For browsing, searching, and manipulating video documents, an indexing technique to describe video contents is required. Until now, the indexing process is mostly carried out by specialists who manually assign a few keywords to the video contents and thereby this work becomes an expensive and time consuming task. Therefore, automatic classification of video content is necessary. We propose a fully automatic and computationally efficient method for analysis and summarization of spots news video for 5 spots news video such as soccer, golf, baseball, basketball and volleyball. First of all, spots news videos are classified as anchor-person Shots, and the other shots are classified as news reports shots. Shot classification is based on image preprocessing and color features of the anchor-person shots. We then use the dominant color of the field and motion features for analysis of sports shots, Finally, sports shots are classified into five genre type. We achieved an overall average classification accuracy of 75% on sports news videos with 241 scenes. Therefore, the proposed method can be further used to search news video for individual sports news and sports highlights.

  • Purpose: The purpose of this study was to analyze students' expectance demand towards high school physical education teaching. Methords : 392 participants randomly selected from one girls' middle school and one girl's high school in each of five tracts and then selected two classes from each of the schools. They were asked to respond to a simple questionnaire about their views on the present physical education teaching. Results : Results showed that about one third of the participants would not choose physical education if the program were offered as an optional subject. Both male and female students ranked psychomotor domain as the top priority among the various learning objectives. Male students favored soccer and basketball while their counterparts liked badminton and volleyball. Over three-fourths of the participants suggested that students' opinions should be considered when teachers plan their program. Conclusion : The results of this study recommended that physical education teaching should be designed with considerations for professional values, societal changes as well as students' expectance on the design of physical education.

  • This study aims to examine the effects of taping of the ankle joint on the static and dynamic balance and gait ability of stroke patients. Twenty-six stroke patients receiving physical therapy at a hospital located in Gyeonggi-do were divided equally into a group that had taping in physical therapy and an ordinary physical therapy group. They exercised for 30 minutes each, 3 times per week for 8 weeks from June to August 2011. Romberg's eye open and eye closed tests, limits of stability(LOS), forward and back test, timed up and go test(TUG) and 10-meter gait velocity test were performed to evaluate static balance, dynamic balance, and gait ability, respectively, prior to and 8 weeks after the intervention. Differences within each group in relation to the lapse of time were compared by a paired t-test. Differences between the two groups were compared by an independent t-test. Regarding comparison of differences within each group, all tests resulted in significant changes in both groups after the intervention (p<.05). Comparison of differences between the two groups showed that taping in the physical therapy group had significantly better test results than the ordinary physical therapy group in all measured items(p<.05). The after effects of ankle taping on stroke patients are more efficient and effective than ordinary physical therapy alone in improving balance and gait ability.

  • This study aims to identify the effect of home physical therapy on patients who left the hospital after total knee arthroplasty, compared to the Daily living group, when it was applied to them, under the guidance of physical therapists. As research subjects, 20 patients that were scheduled to leave the hospital after unilateral total knee arthroplasty, were chosen, and they were randomly divided into a home physical therapy group(10 patients) and an Daily living group(10 patients) in order to conduct an experiment. During the 4-week research, home physical therapy was offered for 40 mins once for 5 days a week, and muscular strength, gait components were measured. For muscular strength, quadriceps muscle strength, hamstring muscle strength were measured, and as gait components, endurance, speed, step time, single-limb support were analysed. For this experiment, pre- and post-measurement were performed, and collected data were analyzed using SPSS ver. 18.0 statistical program. From the analysis of data, the following study results were obtained. Home physical therapy group and Daily living group both showed significant improvements in quadriceps muscle strength, hamstring muscle strength, and quadriceps muscle strength, hamstring muscle strength of home physical therapy group more significantly improved than Daily living group's. In relation to gait components, gait endurance, gait speed, step time significantly improved in both of home physical therapy group and Daily living group, whereas home physical therapy group only showed significant improvements in single-limp support. According to the comparison between two groups, gait speed, single-limp support and step time improved more significantly in the home physical therapy group than in the Daily living group. In conclusion, positive results were revealed in both home physical therapy group and Daily living group, with regard to muscular recovery of lower limbs of patients discharged from the hospital after total knee arthroplasty and walking, but considering the comparison results between two groups, it seems that applying home physical therapy is more effective than maintaining a daily life.

  • In order to compare the cardiac function of various groups of athletes, the resting electrocardiographic time intervals, amplitudes and vectors were analyzed in high school athletes of throwing(n=7), jumping(n=11), short track(n=8), long track(n=14), boxing(n=7), volleyball(n=8) and baseball(n=9), and nonathletic control students(n= 19). All athletic groups showed a significantly longer R-R interval(0.96-1.09 sec) than the controls (0.78 sec). Therefore, the heart rate was significantly slower in atheletes than in the control, but was not different among the different athletic groups. R-R interval is the sum of intervals of P-R, 0-T and T-P: P-R and Q-T intervals showed no difference among the control and athletic groups, but T-P interval in the jump, short track, long track and boxing groups was significantly higher than the control. R-B interval showed a significant correlation with T-P or Q-T intervals but no correlation with P-R or QRS complex. Comparing the amplitude of electrocardiographic waves, the athletic groups showed a lower trend in P wave than the controls. T wave in lead $V_5\;(Tv_5)$ was similar in the athletic and control groups. The long track group showed a significantly higher waves of $Rv_5$, $Sv_1$, and the sum of $Rv_5$ and $Sv_1$ than not only the controls but also the other athletic group. The angles of P, QRS, and T vector in the frontal and horizontal planes were not different among the control and all the athletic groups. Each athletic group stowed a lower trend in amplitude of P vector in the frontal plane, but in horizontal plane, throwing, jump, short track and baseball groups showed a significantly lower than the controls. The amplitude of QRS and T vector was similar in the athletic and control groups, but only the baseball group showed a significantly higher QRS vector in the frontal plane. In taken together, all the athletic groups showed a slower heart rate than the controls, mainly because of elongated T-P interval. Comparing the electrocardiographic waves and vector, the athletic groups showed lower amplitudes of P wave and P vector than the controls. Values of $Rv_5$ and $Sv_1$ strongly suggest that only the long distance runners among the various athletic groups developed a left ventricular hypertrophy.
