The aim of this study is to design and develop the gait rehabilitation equipment that judge patient's movement of his/her center of gravity using pressure sensors, and to aid hemiplegic patients to balance themselves using an automatic stepper that changes the patient's center of gravity. It is hard to bear the weight on the affected side for hemiplegic patients. The gait rehabilitation equipment detects the footing phase of hemiplegic patient during training and moves the unaffected footing side of the stepper up and moves the affected footing side down simultaneously so that the patient's center of gravity can shift from unaffected side to affected side. The gait rehabilitation system was developed and applied for hemiplegic patients during exercise. Eight hemiplegic patients and one normal adult were studied. The developed gait rehabilitation system could judge not only the normal adult's intention but also the patient's intention to move his/her center of gravity. Even though the most of hemiplegic patients exercised in automatic mode and a few hemiplegic patients exercised in manual mode, the developed gait rehabilitation system can aid the hemiplegic patients to train more easily.

Purpose : This study examines the effect of vibration exercise grafting PNF patterns for 6 weeks on upper body stability and equilibrium for seniors having fifteen or over of MMSE-K. Method : A total of 10 senior citizens participated in this study. Each participant performed PNF patterned exercises using vibration sports equipment for 30 minutes, once static a week, for six weeks. We measured trunk stability and balance degree before and after the six-week exercise program. Motor Assessment Scale (MAS) was used to measure trunk stability, while Functional Reach Test (FRT) and Timed Up and Go (TUG) was used to measure balance degree. The collected data was processed using paired t-test to confirm the difference between pre-program conditions and post-program conditions. Results: The results of our study show that post-program trunk stability measurements increased when compared to pre-program data; however, this increase was not statistically significant. pre and post-measurements for satatic balance and dynamic balance were statistically unchanged. Conclusion: Due to limitations in the number of participants, the procedural design of this experiment, and the limited amount of time participants actually controlled, this study failed to produce statistically significant results. However, further study should be conducted using a systematically implemented exercise program to show support for exercising with flexi-bar as an effective program for the elderly.

Increasing the oxidation of fat through exercise is the recommendable method for weight control. Preceding researches have proposed increase in the usage of fat during exercise in stabilized state and under maximum exertion through aerobic training. However, such researches require additional equipment for gas analysis in order to measure the caloric value or gas exchange of subjects during exercise. Such equipments become highly restrictive for those exercise and cause substantially higher cost. According to this, we have presented the method of estimating the maximal fat oxidation point through changes in LF & HF which reflects changes in heart rate and the autonomic nervous system in order to induce exercise for a less restrictive and efficient fat oxidation than existing methods. We have conducted exercise stress test on subject with similar exercise abilities, and have detected the changes in heart rate and changes in LF & HF by measuring changes in fat oxidation and measuring ECG signals at the same time through a gas analyzer. Changes in heart rate and HRV of the subjects during exercising was detected through only the electrocardiographic signals from exercising and detected the point of maximum fat oxidation that differs from person to person. The experiment was carried out 16 healthy males, and used Modified Bruce Protocol, which is one of the methods of exercise stress test methods that use treadmill. The fat oxidation amount during exercise of all the subjects showed fat oxidation of more than 4Fkcal/min in the exercise intensity from about 5 minutes to 10 minutes. The correlation between the maximal fat oxidation point obtained through gas analysis and the point when 60% starts to be relevant in the range from -0.01 to 0.01 seconds for values of R-R interval from changes in heart rate had correlation coefficients of 0.855 in Kendall's method and in Spearman's rho, it showed significant results of it being p<0.01 with 0.950, respectively. Furthermore, in the changes in LF & HF, we have determined the point where the normalized area value starts to become the same as the maximal fat oxidation point, and the correlation here showed 0.620 in Kendall and 0.780 in Spearma of which both showed significant results as p<0.01.

운동은 건강한 삶의 영위에 필요하지만 코로나19와 같은 전염병 유행 상황에서 비대면 환경에서 진행되는 것이 권장된다. 그러나 기존의 비대면 방식의 운동 콘텐츠에서는 운동 동작의 인식은 가능하지만 이를 해석해서 피드백 정보를 제공해주는 과정이 자동화되지 않았기 때문에 피드백이 트레이너의 눈대중으로 이루어지는 한계가 있다. 따라서 본 논문에서는 이러한 문제를 해결하기 위해서 운동 내용 및 이를 구성하는 동작을 추적하기 위해 공식화된 규칙을 만드는 방법을 제안한다. 이러한 규칙을 만들기 위해서는 전체적인 운동 내용의 진행 규칙을 먼저 만들고, 운동을 구성하는 동작의 추적 규칙을 만든다. 동작의 추적 규칙은 동작을 여러 단계로 나누고 단계를 나누는 키 프레임 자세를 정의하는 것에서 출발하여 키 프레임 자세로 대표되는 상태와 상태 간의 전이 규칙을 만듦으로써 생성될 수 있다. 이렇게 생성한 규칙은 모션 캡쳐 장비를 이용한 자세 및 동작 인식기술의 사용을 전제로 하며 이러한 기술 적용의 자동화를 위한 논리적인 전개에 사용된다. 본 논문에서 제안한 규칙을 사용하면 운동 과정에서 나타나는 동작을 인식하는 것뿐만 아니라 동작의 전 과정에 대한 해석의 자동화가 가능하여 인공지능 트레이닝 시스템 등 보다 진보된 콘텐츠 제작이 가능해진다. 이에 따라 운동 과정에 대한 피드백의 질을 높일 수 있다.
