In order to produce a convenient robot for the aged and the lower limb disabled, it is needed for the research detecting implicit walking intention and controlling robot by a user's intention. In this study, we developed sensor module system to control the walking- assist robot using FSR sensor and tilt sensor, and analyzed the signals being acquired from two sensors. The sensor module system consisted of the assist device control unit, communication unit by wire/wireless, information collection unit, information operation unit, and information processing PC which handles integrated processing of assist device control. The FSR sensors attached user's the palm and the soles of foot are sensing force/pressure signals from these areas and are used for detecting the walking intention and states. The tilt sensor acquires roll and pitch signal from area of vertebrae lumbales and reflects the pose of the upper limb. We could recognize the more detailed user's walking intention such as 'start walking', 'start of right or left foot forward', and 'stop walking' by the combination of FSR and tilt signals can recognize.

PURPOSE: This study investigated the activities of lower limb muscles according to the angle of a medio-lateral ramp while walking to promote awareness of the risks associated with a medio-lateral ramp. METHODS: This study was conducted on 20 healthy male adults. The muscle activities of the vastus medialis oblique (VMO), vastus lateralis oblique (VLO), tibialis anterior (TA) and peroneus longus (PL) were measured while the subjects were walking on a 3 m medio-lateral ramp. Five angles (flat, $2^{\circ}$, $5^{\circ}$, $10^{\circ}$, and $15^{\circ}$) were selected for the angle conditions of the experiment on a medio-lateral ramp. The activities were measured during the stance phase only in the middle cycle of a three-cycle walking experiment. The mean value obtained from the three walking tests was used for the analysis. RESULTS: Results showed that walking on a mediolateral ramp required more muscle activities than walking on a flat surface, through which balanced walking was achieved. CONCLUSION: Walking on a medio-lateral ramp requires proper muscle activation and control, without which the risks of injury to the joints of the lower limbs and falls are likely to increase. Therefore, special attention should be given to older people and the disabled under the condition of traversing a ramp.

This research is aimed to develop the functional clothing designs for disabled women in the manner of investigating design preferences among them by means of questionnaire and interview with 150 disabled women as respondents and interviewees. The findings of this research are summarized as follows: 1. Regarding satisfaction with ready-made clothes, the respondents answered 'very satisfied' (1.6%), 'usually satisfied' (14.1%), 'moderate' (20.3%) and 'unsatisfied' (53.1%), suggesting that they had been generally unsatisfied with ready-made clothes. 2. There were more disabled women preferring to ready-made clothes with one-grade bigger (loose.) size than the actual one (53.1%) instead of completely fitted size (43.8%) when they purchased such clothes. This result indicates that they prefer to ready-made clothes with bigger size than the actual one because most of such clothes are made up of non-elastic materials which may be unfavorable for wearer's activities. 3. It was found that primarily worn upper garment among them was T-shirt (59.4%). The reason may be that T-shirt is favorable for using prosthesis and orthotics such as wheelchair, walking stick and crutches thanks to its remarkably high activity as well as simple to maintain, compared with other kinds of upper garments. 4. Regarding preferences to functional clothing designs, the primarily worn lower garment among them was trousers (85.9%); the reason was easiness to move. The main reasons of avoiding to wear a skirt included 'difficult to move' (40.6%) and 'exposed disabled region' (30.3%). Accordingly, functional clothing for disabled women should be developed in consideration for their individual characteristics of disability associated with the disabled region such as wheelchair user, crutch user or brace user, In addition, the designs should be made so that they are not different from those for non-disabled people.
