This study was conducted to promote a LD(Learning Disabilities) student`s positive classroom behaviors. A peer-teaching program that includes training basic skills and activity reinforcements was constructed. The basic skills were sliding and jumping, while the activity reinforcers include a pizza party, participation in a concert, and skateboard demonstration. The transdisciplinary-team model and the peer-teaching method were applied. The subject`s classroom behaviors were evaluated by 40 classroom mates. Effects of the skateboard program were investigated by pre-post test method. To evaluate the subject`s behavior, a behavioral checklist was developed with validity and reliability test. Results of this study indicates that the subjects` classroom behavior were significantly changed after complete of the skateboard program. However, the subject`s personality characteristics were not changed. Scores of the subject`s classroom behavior that was evaluated by male students was greater than that of female students(p$lt;0.05). The different results by the gender was considered to that the male students more likes the skateboard thant the female students. This study also emphasized that promoting useful classroom behaviors, rather than negative one such as aggressiveness, screeming, and roughing, is important to protect increasing negative images.

Children with spasticity cerebral palsy were participated in an Ideokinesiology program to decrease oe control primitive reflexes such as ATNR, Moro reflex, and Righting reflex. An experimental research with 12 subjects in experimental group and 18 subjects involved in a control group were conducted for 10 weeks. Using the QUEST and the BOTMP, subjects` mobility of upper extremity includes hands, neck, arms, and upper body were measured. Results was indicated that subjects` reflexes with hands, neck, and upper body were significantly decreased. However, reflexes with arms were not changed. The Ideokinesiology with image of body parts was an effective methodology to control impropriate mobilities for primitive reflexes of child with cerebral palsy.

For the development of liquid density measuring sensor using the natural frequency of a pipe, its principle and construction method were described. The stainless steel pipe, which has length of 3 cm, inside diameter of 2.3 cm and outside diameter of 2.5 cm, was used for the sensor. The exciting coil and the photo sensor were used to excite and to pick-up it, and the feedback circuit was designed to continue its vibrating. The natural frequency was consistent with the result of the spectrum analysis. It had a linearity of 0.0027 % and a sensitivity of 0.032 in liquid density range from 0.8 g/㎤ to 1.4 g/㎤ and its frequency variation ratio was 0.024 %/℃ in temperature range from 10℃ to 35℃.

The purpose of this study is to examine the effects of two scuba diving methods, the pivot method and the standing method, that are typical methods of scuba diving for learners of beginner levels. The subjects in this study were 69 students in a college, who were beginners of scuba diving. They had no experience of using medications or suffered from any heart diseases. The pivot method group includes 33 subjects who have trained the horizontal alignment of whole body in the water during the experimental sessions. On the while, the 36 subjects of the standing method group practiced the vertical alignment of whole body in the water. A criterion test that was used to make a qualitative analysis of movements was conducted by a course director and seven instructors. As for data analysis, a repeated measure of one-way ANOVA was used to look for differences in scuba diving motions such as sinking motion, waiting motion, swimming motion, floating motion , and neutral buoyancy. The findings of the study were as follows: First, concerning the success rate of sinking motion, floating motion, and neutral buoyancy, there were differences between the pivot method group, and the differences were statistically significant. The subjects of the standing method group scored higher then that of the pivot method group. Second, there were differences between two scores of pre-test and post-teat, that meant both of the pivot method and the standing method were effective to develop the skills of waiting motion and swimming motion. However, the differences between the scores of the pivot method and the standing method were not statistically significant.
