Today’s sports field seems to target only at satisfaction of victory by triumphalism rather than mental and personal appearance. The triumph of sports bring us joy, satisfaction, and happiness. It would be evern better if mental, personal, moral, and ethical maturity are added up at the same time. However, unethical and immoral acts are increasing day by day. Drug abuse, violence, cheating, match-fixing, bad call, foul, embezzlement, and gamble are prevalent as day went by. To prevent these situations, moral and ethical education and system should be prepared. Therefore, the purpose of this study is to recognize the necessity of sports ethics and morality, and to disxuss about the countermeasures, roles, and solutions. The sports field is a mirror of our society. Our society will become sound if sports field is progressed more ethically and morally.

This study was performed to identify structural relationship between involvement and commitment of Taekwondo trainees and intention to continue and recommend it to others. The subjects were 300 elementary school students (Grade 4,5 and 6) out of Taekwondo trainees registered in Kyunggi-do Taekwondo Association in 2013. They were recruited using convenient sampling method and materials from 276 subjects were used for final analysis. Questionnaires were used for the measurement and materials were processed using PASW 21.0 and AMOS 21.0 program. Hypotheses were verified at the level of p<.05 via correlation analysis and structural equation model analysis. First, involvement of trainees had significant effects on commitment to exercise at the level of p<.001. However, joy, self-control and recognition of mistakes did not have significant relationship with involvement. Second, commitment to exercise was found to have significant relationship with intention to continue training at the level of p<.001. Third, commitment to exercise was found to have significant relationship with intention to recommend it to others at the level of p<. 001. Therefore, to enhance the efficiency of management of Taekowndo institutes (training places), it is needed to identify exact purpose of trainees, to have schedule strategy to satisfy trainees’ requirements and demands, and to introduce various marketing and management methods including differentiated program, to improve environments, and provide trainees with careful concern and management so that trainees can have favorable attitudes.

Objectives : The removal of most reliable mechanical dental plaque that is to say tooth brushing was generalized to control of dental plaque, many oral health goods have also developed due to the effect differences followed by individual habit. The electric toothbrush have studied and developed widely as major field of study that electric toothbrush having various moving phase was sold and developed at the market. Methods : Accordingly author studied about selling electric toothbrushes shape (vibration type, ultra-sonic minuteness vibration type, semi rotation type) to raise the efficiency after comparing to the moving them that total 8 groups classified by poor tooth models for example normal set of tooth, crowding tooth, bracket attached tooth, prosthetic status etc. and executed plaque removal effect on the tooth through comparing experiment. Results : The removal rate of artificial plaque on the tooth was improved in proportion to the increase of tooth brushing time(p<0.05). The ultra-sonic minuteness vibration and semi rotation type was superior to toothbrush of vibration type comparing to the removal rate of plaque on the tooth(p<0.05). Conclusions : The electric toothbrush of supersonic minuteness vibration and semi rotation type can be recommended most of tooth types regardless of oral tooth setting status for example, normal set of tooth, crowding tooth, bracket attached tooth, porcelain tooth.
