Abstract: Disclosed herein are a catalyst for low-temperature carbon monoxide purification, a method for manufacturing the same, and a method for purifying carbon monoxide using the same. The catalyst comprises a metal oxide carrier; a transition metal oxide primarily supported on the carrier, and ruthenium secondarily supported on a carrier carrying the transition metal oxide. The catalyst provides an effect capable of purifying carbon monoxide contained in a hydrogen gas at a low temperature.

Abstract: Disclosed is a motion-mode- and thumb-position-based motion control system and method of a myoelectric hand, and more particularly a motion-mode- and thumb-position-based motion control system and method of a myoelectric hand that is capable of performing a hand motion indicating emotion or intention expression as well as a grasping motion for holding an object according to restrictive electromyography signals transmitted from two electromyography sensors provided at the myoelectric hand and that is capable of diversifying hand motions and grips depending on the position of a thumb that can be changed by a user, whereby a utilization range of the myoelectric hand is simply extended.

Abstract: The present invention relates to an artificial foot including a foot body part, a toe part rotatably disposed at a first end of the foot body part, a toe joint connecting the foot body part and the toe part to each other, and an adapter disposed on a top of a second end of the foot body part. According to the artificial foot, since the toes of the artificial foot rotate when a wearer walks, when the artificial toes come in contact with the ground, energy is stored due to the load by the weight and the toes kick off the ground as much as the elastic energy accumulated by the spring, so the toe members of the artificial foot do not drag on the ground. Accordingly, the wearer does not need to lift up the hip joints, so the wearer can walk similar to normal walking.
