  • In this paper, we propose a multimedia recommender system using user's playback time. Proposed system collects multimedia content which is requested by user and its user‘s playback time, as web log data. The system predicts playback time.based preference level and related contents from collected transaction database by fuzzy association rule mining. Proposed method has a merit which sorts recommendation list according to preference without user’s custom preference data, and prevents a false preference. As an experimental result, we confirm that proposed system discovers useful rules and applies them to recommender system from a transaction which doesn‘t include custom preferences.

  • The purpose of this study was to investigate the effect of rotational preference on body stability based on COP and EMG analysis in an quiet standing after turn in the left and right directions. The subjects of this study were 16 subjects with a high lateral preference for the right hand and foot. The subjects of this study were 16 subjects with high unilateral preference for the right hand and foot, and three rotational direction conditions (QS: quiet standing, LT: 10 turns on the left, RT: 10 turns on the right) were performed. In order to evaluate the stability in an quiet standing after turning, the results were derived and analyzed using a COP plate and an EMG. As a result of the study, LT and RT were larger than QS for all COP variables, but there was no difference according to the direction of turning. In EMG, RT showed larger muscle activity than the QS according to the rotational direction in left and right gastrocnemius. In conclusion, although all subjects had a high right lateral preference, there was no effect of rotational preference in COP, and gastrocnemius showed the effect of rotational preference.

  • This study aims to standardize Moral Judgment Test (MJT) for measure the level of moral judgment to apply to Korean society. The questionnaire of MJT was composed of two stories: Worker's Dilemma; Doctor's Dilemma. The procedure of this study was started with translation, making final questionnaire through several times pre-test, survey, then did analyze. The degree of reliability was .669. To verify validity, this study carried 3 kinds of tests as follows: the Order of Preferences, Quasi-simplex Structure, Cognitive-Affective Parallelism. Through these tests, this study showed that Korean-translated version questionnaire of MJT is significant and good base to measure moral judgment.

  • Objective : The purpose of this study was to investigate the efficacy of electromyogram-triggered neuromuscular stimulation in the treatment to Guillain-Barre Syndrome patients of through case Study. Methods : The subject was a 66-year old woman who has Guillain-Barre Syndrome, showed wrist and hand function decrease in FMA and JTHFT investigation. She received a electromyogram-triggered neuromuscular stimulation treatment for 4weeks, 1 per day, 30 minute for each(right, left). Results : After 4 week period, wrist and hand function of FMA was observed increase and JTHFT showed improvement in some items. Conclusion : The use of electromyogram-triggered neuromuscular stimulation in the treatment of Guillain-Barre Syndrome who had peripheral neuropathy could been effective to therapy for motor recovery.
