The purpose of this study is to provide guideline of muscle strengthening exercise for preparing ambulation by presenting suitable ratio of muscle power of agonist & antagonist, and that of concentric & eccentric contraction on behalf of amputee's normal ambulation training and it's strenthening as well. 7 Subjects who have femur amputee for experimental group were able to ambulate naturally without inconvenience and 20 adult subjects of comparison group for comparison were considered to be free from disturbance of ambulation. The method of study was to measure the muscle power of hip pint, was to figure out the ratio of agonist & antagonist, concentric contraction & eccentric contraction, and was to find out mean and standard deviation of each measurement. Every numerical value of comparison was tested by Mann-whitney and comparison group's comparison between left & right value was done with t-test. Results are as followings : 1) Extension force was stronger than flexor force and had no remarkable difference(p<0.05) 2) For normal adults, adduction farce was stronger than abduction force and for amputees, abduction force was stronger while adduction force was the same as the normal without showing remarkable difference(p<0.05) According the result above, I make an assumption that maintaining a proper ratio of muscle power on strengthening exercise for amputee's ambulation training & rehabilitation and finally bring out an improvement of transfer and ambulation.

본 연구는 뇌성마비아동들을 대상으로 보이타 치료법을 적용하여 개체발생학적 병적자발이동능력, 폐활량, 손기능, 균형 및 보행에 미치는 영향을 알아보고자 하였다. 본 연구의 대상자는 만 6세 ~ 10세(평균 7.4세)의 경직형 하지마비와 편마비 타입의 뇌성마비 아동들로 혼자서 최소 3m 보행이 가능한 아동들 중 개체발생학적 병적자발이동 (ontogenesis spontaneous pathologic locomotion; OSPL)에서 6 stadium 이상 수 준의 완전한 독립보행이 안 되는 9명의 아동들을 선별하였다. 운동은 회당 30분, 주 4회, 6주간 실시하였으며 검사는 치료 전ᆞ후로 각 1회씩 실시하여 다음과 같은 결과를 얻었다. 운동 후 뇌성마비아동들의 OSPL은 9명 중 5명에서 각각 1단계씩 상향되었고, 폐활량, 소아 균형 척도의 유의한 증가(p<.05), 서고 걷기 시간 검사의 유의한 감소 (p<.05)를 보였으며, 젭센-타일로 7가지 손 기능 평가 항목 중 작은 물건 옮기기와 먹기 흉내내기, 크고 가벼운 깡통 들어올리기는 비우세손과 우세손 모두 통계적으로 유의한 차이를 나타냈으며(p<.05), 크고 무거운 깡통들어올리기 항목은 우세손에서만 유의한 차이를 보였다(p<.05). 본 연구 결과를 통해 보이타의 반사적 전진이동운동이 경직형 뇌성마비 아동의 폐활량, 손기능, 균형 및 보행 향상에 효과적인 것으로 나타났다. 향후 좀 더 다양한 질환 및 연령에 보이타 치료를 적용한 연구가 필요하겠다. The purpose of this study was to evaluate the effects of an Vojta’s reflex forward movement on ontogenesis spontaneous pathologic locomotion (OSPL), vital capacity, hand function, balance and gait for children with spastic cerebral palsy. Nine children with spastic cerebral palsy, ages 6 to 10 years, participated in Vojta’s reflex forward movement program 4 times per week for 30 minute for 6 weeks, and were tested before and after the intervention. The outcome measures included OSPL, Forced expiratory volume 1sec(FEV1), Jebsen-Taylor hand function test, Pediatric balance scale and Timed up and go test. Significant differences were found in OSPL, vital capacity, hand function, balance and gait. The results of this study provide evidence that children with spastic cerebral palsy can improve their OSPL, vital capacity, hand function, balance and gait after Vojta’s reflex forward movement.

Recently, the safety in vehicle also has become a hot topic as self-driving car is developed. In passive safety systems such as airbags and seat belts, the system is being changed into an active system that actively grasps the status and behavior of the passengers including the driver to mitigate the risk. Furthermore, it is expected that it will be possible to provide customized services such as seat deformation, air conditioning operation and D.W.D (Distraction While Driving) warning suitable for the passenger by using occupant information. In this paper, we propose robust vehicle occupant detection algorithm based on RGB-Depth-Thermal camera for obtaining the passengers information. The RGB-Depth-Thermal camera sensor system was configured to be robust against various environment. Also, one of the deep learning algorithms, OpenPose, was used for occupant detection. This algorithm is advantageous not only for RGB image but also for thermal image even using existing learned model. The algorithm will be supplemented to acquire high level information such as passenger attitude detection and face recognition mentioned in the introduction and provide customized active convenience service.
