Electrically operated hospital bed and operating table are useful devices to care patients and to keep postures of them in medical treatment. However they have the risk of physical injury due to various functions and mechanisms consisting of them. In this paper we propose particular requirements for the safety and test methods of electrically operated hospital beds and operating table classified into medical devices. Each items are developed based on international standards. The results of this study can be used for developing internationally harmonized standards for the approval of Korea Food and Drug Administration (KFDA).

In this paper, we proposed how to estimate the walking state in the knee disarticulation prosthesis's knee angle control. In control of the knee disarticulation prosthesis, we can estimate walking state that measurement of knee angle using absolute encoder and measurement of load on the soles using strain gage. We suggested a method of estimating the current walking states which can be divided into four cases and showed the effectiveness of the method via a series of experiments.

In this paper, we apply limited area mask operation and active contour model to accurately detect tongue area outline in tongue diagnosis system. To accurately analyze the properties of the tongue, first, the tongue area to be detected. Therefore an effective segmentation method for detecting the edge of tongue is very important. It experimented with tongue image DB consists of 20~30 students 30 people. Experiments on real tongue image show the good performance of this method. Experimental results show that the proposed method extracts object boundaries more accurately than existing methods without mask operation.

This paper proposes a data glove for a rehabilitation robot interface for the upper extremity paralysis. The designed data glove uses seven flexible sensors so as to measure the flexion angles of fingers and wrist. We verified the performance of the data glove using a 3D graphic interface developed. The experimental results show that the proposed data glove is feasible to sense hand motions and applicable to the robot interface.

This paper propose the test method for a performance of the myoelectric hand prosthesis(MHP) controlled according to the myoelectric signal generated in the human muscle. The MHP consists of a mechanical hand, a surface myoelectric sensor(SMES) for a measuring myoelectric signal, a control system and a charging battery. The two commercialized MHP is tested for the grip endurance property. The test results is not difference a noise and a grip force. The proposed test method is proved the reliability of MHP by the endurance test.

In this paper, we developed a finger robot simulating spasticity and contracture which can be used as a testing bed for evaluating performance of hand rehabilitation devices while it can be also used to train clinicians for improving reliability of clinical assessment. The robot is designed for adult finger size and for independent control of Metacarpophalangeal Joint and Proximal Interphalangeal Joint. Algorithm for mimicking spasticity and contracture is implemented. By adjusting the parameters related to contracture and spasticity, the robot can mimic various patterns of responses observed in fingers with spasticity and contracture.

Demand of moving auxiliary equipment has increased recently to an increase in the elderly population. pedestrian demand is either moving auxiliary equipment are also increasing. regional migration, such as pedestrian and the elderly and patients is a device to support the sharing received walking the weight of inconvenient people. In this paper, by mounting the electric function to the current manual walking, to prepare the electric walking to support the user's walking. the design applies a lightweight folding structure so that it can be moved to a ride at long distances, were fabricated.

In this paper, we propose a intelligent retrieval system with interactive voice support. The developed system helps to find misrecognized words by using the relationship between lexical items in a sentence recognition and present the correct vocabulary. In this study, we implement a simulation system that can be proposed to determine the usefulness of the product search assistance system which offers applications. Experimental results were confirmed to correct the wrong speech recognition vocabulary in a simple user interface to help the product search.
