  • Various applications of exoskeleton system are reported in the area of military, healthcare, and industries. More the user gets help from exoskeleton system, more power is consumed. To resolve this design conflict, we suggest an energy efficient exoskeleton system which compensates muscle fatigue in isotonic and isometric contraction conditions. Fatigue compensated exoskeleton significantly reduced muscle fatigue while consumed less operation power. In addition, the level of fatigue compensation can be managed by motor control using various input profile. It can make user customized exoskeleton system.

  • In this letter, we propose a dual autostereoscopic display platform employing a natural interaction method, which will be useful for sharing visual data with users. To provide 3D visualization of a model to users who collaborate with each other, a beamsplitter is used with a pair of autostereoscopic displays, providing a visual illusion of a floating 3D image. To interact with the virtual object, we track the user's hands with a depth camera. The gesture recognition technique we use operates without any initialization process, such as specific poses or gestures, and supports several commands to control virtual objects by gesture recognition. Experiment results show that our system performs well in visualizing 3D models in real-time and handling them under unconstrained conditions, such as complicated backgrounds or a user wearing short sleeves.

  • Hot and humid weather in summer generally brings about discomfort. Experiments on which relative humidity makes effects on the comfort sensation were performed to the young and the aged using sensation vote. From July to October 1996, seven college students and eleven aged people were exposed for 2 hours under six different conditions in the Pukyong National University test chamber so as to determine the effects of relative humidity on thermal and comfort sensations. Subjects were wearing same clothes, and the mean clo value was 0.5. The mean radiant temperature was equal to the air temperature and air velocity in the occupied zone around 0.lm/s. In the experiments, it was found that discomfort could be largely reduced when the humidity is controlled to low values in the settled high temperature.

  • Up to 10% of the global population suffers from color vision deficiency (CVD) [1], especially deuteranomaly and protanomaly, the conditions in which it is difficult to discriminate between red and green hues. For those who suffer from CVD, their career fields are restricted, and their childhood education is frustrating. There are many optical eye glasses on the market to compensate for this disability. However, although they are attractive due to their light weight, wearing these glasses will decrease visual brightness and cause problems at night. Therefore, this paper presents a supplementary device that comprises a head-mounted display and an image sensor. With the aid of the image processing technique of digital color space adjustment implemented in a high-speed field-programmable gate array device, the users can enjoy enhanced vision through the display without any decrease in brightness.

  • Objective: The purpose of this research was to determine the immediate effects of wearing a foot-pressure-based insole (FPBI) on ankle dorsiflexion range of motion (DFROM), postural sway, and muscle activation in healthy individuals with genu varum. Design: Cross-sectional study. Methods: This study was conducted on thirteen adults, with six male and seven females subjects. The mean age was 24.08 years. Foot pressure was measured to apply the FPBI and the weight bearing lunge test was performed with the application of a flat insole (FI) and FPBI. Examination was randomly performed in four conditions to measure both postural sway and muscle activation. All participants applied both the FI and FPBI with four conditions. The four conditions were as follows: 1) Romberg test posture with eyes closed, 2) Romberg test posture with eyes opened, 3) dominant single leg standing with eyes opened, and 4) non-dominant single leg standing with eyes opened. Results: For ankle DFROM between the FI and FPBI, a significant increase was observed in both the dominant and non-dominant leg (p<0.05). For postural sway between the FI and FPBI in the Romberg test posture with eyes closed and dominant single leg standing with eyes opened conditions, a significant decrease was observed (p<0.05). However, the postural sway between FI and FPBI in the Romberg test posture with eyes opened and non-dominant single leg standing with eyes opened, no significant decrease was observed. Also, there were no significant effects on muscle activation between the application of the FI and FPBI. Conclusions: The result showed that FPBI immediately improved ankle DFROM and postural sway. It seems that FPBI may improve genu varum in healthy individuals with genu varum.

  • The social understanding of the rehabilitation and welfare work for the handicapped children is nearly devoid in Korea. Especially the medical rehabilitation or nursing for them is left ign. ored as well as the literature preferential to this study is wanted. For the purpose of conducting the study of this thesis Sam Yook Children's Rehabilitation Center, Inc. and Crippled Children's Center, Yonsei University Medical center sampled out; covering three months from Aug. 1 to Oct. 30, 1973, the problems of children's rehabilitation, the characteristics of the children, the medical rehabilitation, nursing, education, and vocational rehabilitation were interviewed and widely grasped. This thesis aimed at developing the rehabilitation, the professional nursing and especially aimed at contributing to the improvement of welfare for the handicapped by analysing, observing the result of this study. The result is as follows: 1. Sam Yook Children's Rehabilitation Center, Inc. has, since its establishment, contributed to the advancement of the crippled children and its purpose consists in implementing services, medical rehabilitation, nursing, education and vocational training. Crippled Children's Center, Yonsei University Medical Center is, being based on Christianity, aiming at the medical treatment and education for the crippled children. 2. All of the children admitted in the children's rehabilitation centers are the crippled children. The ratio of boys io girls is three to two. Boys are more than girls. Orphan formed 55.2 per sent of them. About 60 per cent of them is receiving medical attention free of charge. But there is no orphan in Crippled Children's Center, Yonsei University Medical Center. 3. 15.7 per cent of them have received the previous medical attention before their admitting in the centers; in Sam Yook Children's Rehabilitation Center 8.6 percent, Crippled Children's Center, Yonsei University Medical Center 50 percent; there is remarkable difference between the two. 4. On the standpoint of period of being in the centers, the children who have been over three years in Sam Yook Children's Rehabilitation Center formed 48.7 per cent; in Crippled Children's Center, Yonsei University Medical Center 2.6 percent; there is also considerable difference between the two; they couldn't discharge from the centers owing to the economic conditions and being orphan. 5. Among the diagnosis of the crippled children, poliomyelitis formed highest 51.7 percent of them ; cerebral palsy formed 30 percent secondly in order. Environmental factors (67.8 percent formed about three times of congenital factors (23.7 percent). 6. The children who are capable of doing independently activity of daily living formed 87.9 percent; 73.2 percent can walk about 300 m by wearing brace and so on. The ratio of wearing brace or leg prosthesis formed 47.4 per cent: crutch 44.3 per cent. The medical rehabilitation service and education for the crippled, are comparatively well carried out. But it is desired to improve and cultivate the vocational training, vocational guidance and special nursing to the insufficiency of their implementation. In the tendency that the rehabilitation and welfare for the handicapped are today emphasized, International Handicapped Rehabilitation Association, declaring that 1970s are the decade of rehabilitation, urged to improve positively the policy of rehabilitation and welfare for the handicapped. But here in korea the handicapped, being the object of social prejudice, ignorance, disdain lives in obscurity. Therefore the government or the community should draw up countermeasure on social under-standing, financial support, and rehabilitation services for the handicapped as well as should endeavor to make them participate in social activities as the productive total- person though they are physically imperfect.
