The purpose of this study was to investigate the effects of 8 weeks of core training on the abdominal muscle strength, sargent lumps, Y-balance and equilibrium freestyle skiers'. Fourteen freestyle players were randomly assigned to the exercise group(Ex)(n=7) and control groups(Con)(n=7). Ex undertook a 8-week training program that included exercises for the Bench, Sideway bench, and Nordic hamstring whereas Con performed their usual activities. Muscular fitness were significant effect observed, but there was no difference between groups. The Y-balance test was effective in the front left, and the left and right left posteromedial showed significantly differences between the groups. In the total score, the Ex decreased to 7.5cm in the left and right difference and 1.66cm in the post, but the control group increased from 3.73cm in the pre-test to 7.01cm in the post-test. In the Equilibrium test, there was significant result in condition(C) in C2, C5, and C6. In conclusion, the 8-week core training was found to have a beneficial effect on the postural control in freestyle skiers'.

This study aimed to compare the effectiveness of action-observational training and task-oriented training on upper limb function and activities of daily living in patients with post-stroke hemiparesis. This study included 12 voluntary participants with post-stroke hemiparesis. Subjects were randomly assigned to either group 1 or group 2, with 6 in each group. Each subject completed the crossover experiment that comprised of action-observational training (A) and task-oriented training (B). The intervention sequence was A-B for the group 1 and B-A for the group 2. Each training was performed for 30 min a day, 5 times a week for 2 weeks (total experimental period of 4 weeks). Assessments were made using the Wolf Motor Function Test (WMFT) and Modified Barthel Index (MBI) thrice: at baseline, after 2 weeks of intervention, and after 4 weeks of intervention. The results showed that the WMFT and MBI scores significantly improved after the completion of each training (p<.05). Therefore, a determination of the superior training method was difficult. The effect sizes of both groups were greater when performed the action-observational training. The findings suggest that both the action-observational training and task-oriented training may be helpful in improving the upper limb function and activities of daily living for patients with post-stroke hemiparesis, and support the clinical feasibility of the action-observational training.

This study was conducted to compare the effect improving balance abilities of 3 balance training programs by randomized intervention trial. Study subjects were 29 female students recruited from a university in Gwanju, who allocated randomly to 3 intervention groups, aqua group(modified Halliwick 10 point program, N=10), visual bio-feedback balance training group(N=10), and balance-pad plus trampolin group(N=9). As the results of repeated musure ANOVA, Wilcoxon signed rank test, major research findings were as follows; 1. Regarding SI or BIEMG measured at upright posture on hard platform, bio-feedback group under the condition with opening both eye and aqua group under the condition with closing both eye showed signigicant improvement in balance ability, respectively. 2. Regarding SI or BIEMG measured at upright posture on soft platform, bio-feedback group under the condition with opening both eye and aqua group under the condition with closing both eye showed signigicant improvement in balance ability, respectively. 3. Regarding all 3 sensory ratios, bio-feedback group showed significantly higher increasement in them than other 2 groups. The results suggested that visual bio-feedback training program improve the all 3 sensory functions required for balancing, and aqua training modified from Halliwick 10 point program contribute to improve vestibular function principally.

The purpose of this study was to investigate the effect of dual task training on postural stability and balance in chronic stroke patients. A total of 25 ambulatory hemiplegic stroke patients were recruited into this study and randomly assigned into two groups, the dual task training group (n=13) and control group (n=12). Both groups received general physical therapy for 30 minutes a day, 5 days a week during 6 weeks. In addition, dual task training group received dual task training programs for 50 minutes a day, 3 days a week during 6 weeks. The scores of Trunk Impairment Scale (TIS), Postural Assessment Scale for Stroke (PASS) and postural sway with eye opened and eye closed on the Force Plate were assessed before and after intervention. Postural stability and balance significantly improved after training in the dual task training group(p<0.05). The result suggests that dual task training is feasible and suitable for individual with chronic stroke.

Recently keeping pace with globalization, many international conferences and athletic games are being held in Korea. After 911 terror in New York in 2001, Korean government dispatched Zaytun Division in Iraq and this fact has also led to voice concerns that Korea should be prepared to protect from terrors of chemical, biological, radiological, nuclear, and explosive(CBRNE) emergency as soon as possible. It is important to develop the CBRNE emergency medical training for fire officers in Korea. So I propose the curriculum.

The purpose of this study was to investigate the muscular activity and muscle strength for swing track of upper limbs during rowing exercise. Subject was all twenty healthy adults and they were divided into linear exercise group and elliptical exercise group in random. Subjects performed rowing exercise 3-times for a week and performed all 8-weeks. We measured realtime-surface EMG. Also we measured joint torque of elbow, ankle and lumbar in subjects using BIODEX. The result showed that when rowing exercise, elliptical track exercise had higher muscular activity in trapezius, deltoid, erector spinae, rectus femoris, biceps femoris, gastronemius than linear track exercise on more many muscle of upper and lower limbs. Also elbow joint torque and lumbar joint torque was more higher too. but linear exercise also had higher muscular activity in multifidus, tibilalis anterior than elliptical track exercise. According to this experiment, we found out that elliptical track was more efficient than linear track.

Objective : This study was to evaluate the effects of a Neurofeedback(NFB) and Computer Assisted Cognitive Rehabilitation(CACR) training to improve on cognition and affected arm function in stroke subjects. Methods : Participants were randomly allocated to three groups: NFB(n=14), CACR(n=14) and control(n=16). All groups received occupational therapy and physical therapy for 5 session 30 minutes per week during 6 weeks. Also NFB and CACR group practiced additional NeuroComp training and RehaCom training for 30 sessions 30 minutes during 6 weeks. Results were evaluated by cognition, affected arm function. Results : There were significantly increased by CACR training that outcomes of MMSE-K(p<.05). And there weren't significantly difference by NFB and CACR training that outcomes of the affected arm function. And a difference between three groups wasn't found. Conclusion : The NFB and CACR training improves cognitive function. These results suggest that NFB and CACR training is feasible and suitable for individuals with stroke.

본 논문에서는 오픈 소스인 openpose skeleton tracking 기술을 이용하여 특정 운동 동작을 영상처리 기술과 딥러닝 기술로 인체 자세에 대해서 인지와 상황 판단하여 운동 동작에 대한 인식 결과를 도출할 수 있다. 먼저 입력받은 영상을 전달받아서 딥러닝 인식 시스템를 통해 인식 결과을 추출한 뒤 비교, 분석한 후에 사전 등록된 운동 동작 명칭으로 화면에 표시하여 이용자가 정확한 동작을 취할 수 있도록 지도하는 데 활용할 수 있다. 또한, 이 기술은 행동 인식부터 얼굴 인식, 손동작 인식 등에 다양하게 활용할 수 있다.
