G. B. LEE, A. S. GWON, The Research for Using methodof GRF (Ground Reaction Force) on Rotational Movement in Arabesque. Korean Journal of Sport Biomechanics, Vol. 15, No. 2, pp.1-10, 2005. As, in relation to all movements of a human being, the movements such as mutually walking, running, rotating, and jumping are attained endlessly through the ground amid the interaction with the ground, in terms of the harmonious movement of the upper limbs and the lower limbs, related to the basic movement in ballet, the type of a movement depends on the size and direction of the force that presses down the ground (Fz, Fx, Fy) amid the interaction with the ground. Therefore, aiming to correctly and efficiently perform a rotational movement in Arabesque, this study analyzed factors of the force manifestation through GRF (Ground Reaction Force), by dividing into preparing, stepping, standing, rotating, and finishing stages (events (1) ${\sim}$ (5)), targeting the subjects of 4 elite female students who majored in ballet. 1. At the No.5 position of the preparing stage, It is necessary that support the ground with left and right foot balance, 2. As the stepping stage is the phase ranging from the event (2), in which a plie movement of bending a knee is started, to the event (3) of stretching a knee, Rebunding motion is not good, and One have a position with ankle and knee flextion condition in order to stretch strengthly in event (3) position 3. At the event (1) position, It is necessary that exert the Fz reaction force at the event (3) position. Because large stretch force help to have a toe on position easily and show a active motion 4. In order to have a stand and rotation motion smoothly, One need a muscle strength training for ankle extension, knee extension, control horizental force

PURPOSE: This study examined whether a task-oriented training program is an effective intervention to improve the body function, activity, and participation of children with cerebral palsy (CP). METHODS: Ten children with CP (7-13 years old) performed a task-oriented training program for eight weeks (three sessions per week, 30 minutes each). The taskoriented training program consisted of eight activities. The subjects' body function was assessed using a handheld dynamometer, goniometer, Modified Ashworth Scale (MAS), Balance Performance Monitor (BPM), and the Bruininks-Oseretsky Test of Motor Proficiency (BOTMP). The subjects' activity and participation were assessed using the Gross Motor Function Measure (GMFM) and Timed Up and Go (TUG) test. RESULTS: Task-oriented training provided significant improvements in the subjects' body function. The subjects improved the bilateral isometric muscle strength of the hip flexors, extensors and abductors, knee flexors and extensors, and ankle dorsi- and plantar flexors (p<.05). Bilateral passive hip flexion, abduction, and external rotation, knee flexion, and ankle dorsi- and plantar flexion were also increased (p<.05). In addition, the MAS score of the hip adductors decreased (p<.05) and the BOTMP score increased after training (p<.05). The subjects' activity and participation also improved significantly after training, increasing the GMFM score (p<.05) and decreasing the TUG score (p<.05). On the other hand, the BPM score did not change after training. CONCLUSION: This study suggests that a task-oriented training program can be an effective intervention to improve the body function, activity, and participation for children with CP.

Adequate postural control depends on the spatial and temporal integration of vestibular, visual, and somatosensory information. Especially, the musculoskeletal function is essential to maintain the postural control. The experimental studies was performed on the muscular activities in the lower extremities during maintaining and moving exercises on an unstable platform with Magneto Rheological(MR) dampers. The unstable platform of the developed system was controlled by electric currents to the MR dampers. A subject executed the maintaining and moving exercises which are presented through the display monitor. The electromyographies of the eight muscles in lower extremities were recorded and analyzed in the time and the frequency domain: the muscles of interest were rectus femoris(RF), biceps femoris(BF), tensor fasciae latae(TFL), vastus lateralis(VL), vastus medialis(VM), gastrocnemius(Ga), tibialis anterior(TA), Soleus(So). The experimental results showed that the muscular activities differed in the four moving exercises and the nine maintaining exercises. For the anterior-posterior pattern, the TA showed highest activities; for the left-right pattern, the TFL; for the 45, $-45^{\circ}$ pattern, the TFL and TA. Also, the rate of the increase in the muscular activities were affected by the condition of the unstable platform with MR dampers for the maintaining and moving exercises. The experimental results suggest that the choice of different maintaining and moving exercises could selectively train different muscles in various intensity. Futhermore, the findings suggested that the training using this system can improve the ability of postural control.

The purpose of this study was to evaluate the effectiveness of an intervention program using dietary consult and physical exercise conducted by public health center in Chuncheon city for obese adults. This study used a pretest-posttest design. The subjects were 58 out of 90 obese adults with body mass index (BMI) greater than $25kg/m^2$ who completed all education sessions for 8 weeks. Data on dietary habits, dietary behaviors, nutritional knowledge, anthropometric parameters and biochemical indices and daily nutrient intakes assessed by a 24-hour recall were collected before and after the intervention program., in order to evaluate program effectiveness. After the intervention, there were positive changes in exercise status and dietary habits and nutrition knowledge accuracy. Especially, the answer of 'I drink a cup of milk every day' were significantly improved (p<0.001), and the answer of 'I don't overeat', which is a dietary attitude question was significantly improved (p<0.05). Dietary intakes of most of nutrients were not significantly different between pre-test and post-test. But calcium (p<0.05), potassium (p<0.05), vitamin A (p<0.01), vitamin E (p<0.05), and folic acid (p<0.05) were significantly increased in the female group after the intervention. Weight (p<0.05), BMI (p<0.01), blood pressure (p<0.001), were significantly decreased after program, but changes of skeletal muscle mass, body fat mass were not significant. Resting heart rate (p<0.01), flexibility (p<0.001), whole body reaction (p<0.05), grip strength (p<0.01) and balance (p<0.01) showed positive changes after the intervention. Blood glucose level in serum was significantly decreased (p<0.001).

Purpose: This study aimed to evaluate the effectiveness of a customized health promotion program (CHPP) on depression, cognitive functioning, and physical health of elderly women living alone in the community. Methods: A randomized comparison of pre-and post-test design was used with 62 participants assigned to either an intervention (n=32 in seven clusters) or a control group (n=30 in seven clusters) in 14 areas of a town. The final sample included 30 intervention participants who completed the CHPP for 10 weeks, and 26 control participants. The intervention group participated in the CHPP weekly; they were provided with instructions about coping with their chronic illnesses, lifestyle modification, risk management, providing emotional support to each other, and floor-seated exercise, which they were encouraged to do three times a week in their homes. Results: Significant group differences were found in depression (U=48.50, p<.001), cognitive functioning (U=2.50, p<.001), left arm flexibility (U=251.50, p=.023), right arm flexibility (U=225.00, p=.007), static balance (U=237.00, p=.012), and gait ability (U=190.50, p=.004). However, there were no significant differences in bothgrip strength and muscle mass between the two groups. Conclusion: The findings indicate that CHPP was overall effective at improving depression, cognitive functioning, and physical functioning of elderly women living alone, and could therefore be considered a positive program for community-dwelling elderly women living alone.
