This study is aimed to identify latent classes which are based the change patterns in assistive technology device use among worker with disabilities and to test the effects of independent variables(gender, education, disability type, disability density, activity and participation of ICF: ICF, subjective socioeconomic status: SES, job satisfaction, life satisfaction) on determining latents classes. This study applied Nagin's(1999) semi-parametric group based approach to the panel survey of employment for the disabled. Because dependant variable has dichotomous scale, logit model was used. The results identified three latent classes, which could be defined based on the patterns as follows; assistive device continued use group, assistive device mid-level use group, assistive device sharp decline use group. The effects of the independent variables on the latent classes was tested by multinomial logit analysis. The results showed that education, disability type, ICF, SES, and life satisfaction were significant determinants of the latent classes. Finally, the implications based on analysis results were suggested.

PURPOSE: This study examined the status of the efficient supply of assistive devices for students with disabilities. METHODS: A complete investigation was conducted on the request and supply of assistive devices for students with disabilities at the Korea National University of Welfare. The subjects were 112 students with disabilities who applied for assistive device rental. The status of the supply of assistive devices according to the type of disability was investigated. The overall satisfaction with learning support was measured. The questionnaire content was categorized into the following three factors to determine learning support satisfaction: support overall (role, staff, facilities) learning support (learning support, learning counseling, life consultation), assistive device supply (counseling, rental, uses, rental period, maintenance services). RESULTS: The most common type of students with disabilities was physical disabilities 62 (29.38%) and hearing impairments 62 (29.38%). Students with physical disabilities and brain lesions rented manual and electric wheelchairs the most. Learning support satisfaction was evaluated considering the factors support overall, learning and assistive device supply effects. satisfaction of learning support for students with disabilities 83.5 points. CONCLUSION: The satisfaction with assistive device supply appears to be relatively lower than support overall. Each university will gradually secure assistive devices that suit the characteristics of students with disabilities.

This research is focused on improvement of satisfaction of the assistive products, which is used by long term care elderly people. We investigated 1,200 long-term cared elderly and this survey was conducted by care-giver. The average satisfaction of the assistive products are in convenience 3.43, in function and effectiveness 3.33, in safety and secure 3.29 and in adequacy cost compared to effectiveness 2.69. Total average satisfaction of utilization is 3.19. Satisfaction with the use of assistive products in using motivation does not show a statistically significant difference, but in selection factors is a difference to be statistically significant. In conclusion, expert-consulting should be enhanced for the improvement of satisfaction and the provision of assistive products should be expanded in long-term care insuance schemes. Also, the rational index and evaluation method of the satisfaction of the assistive products should be developed through continuous studies.

This paper is case study on design, manufacture and application of customized assistive device for the ADL of person with brain lesions. The study had carried out from October 2010 to November 2010 and 2 clients from Assistive device case management demonstration project which is performed by Daegu assistive and rehabilitation center had participated. Case A, a 47-year-old man with brain lesions, stays only on the floor and could not get close to the usual toilet by himself because of the poor low extremities muscle strength and function. The moveable-toilet and customized ramp had applied to Case A. He clambers up the ramp and reach to the toilet easily. Case B, a 8-year-old boy with brain lesions, had difficulties with self-feeding because of his clumsy hand. Several existing feeding aids were applied but not appropriated. A customized feeding aid was designed and manufactured out of regard of Case A's ROM and right hand size. And his occupational therapist works together continuously to make him feed himself in the near future. Already-made assistive devices were not appropriate to Case A and B and to solve this problem, customized assistive devices were applied. The importance and needs of design and manufacture of assistive device were recognized through these case study.

This paper describes an intelligent ankle assistive robot which provides assistive power to reduce ankle torque based on an analysis of ankle motion and muscle patterns during walking on level and sloped floors. The developed robot can assist ankle muscle power by driving an electric geared motor at the exact timing through the use of an accelerometer that detects gait phase and period, and a potentiometer to measure floor slope angle. A simple muscle assistive link mechanism is proposed to convert the motor torque into the foot assistive force. In particular, this mechanism doesn't restrain the wearer's ankle joint; hence, there is no danger of injury if the motor malfunctions. During walking, the link mechanism pushes down the top of the foot to assist the ankle torque, and it can also lift the foot by inversely driving the linkage, so this robot is useful for foot drop patients. The developed robot and control algorithm are experimentally verified through walking experiments and EMG (Electromyography) measurements.

The Law method is observing the temporal bone. There are two types of methods: the double angle method, which manipulates the center ray angle of the tube twice, and the single angle method, which manipulates once. The purpose is to increase the reproducibility of the image by making vertical incidence by making an assistive device using a 3D printer. Two assistive devices with a wedge-shaped 8.5 × 10 × 2.3 cm, an inclined surface of 7.5 cm, and an inclination angle of 15° were fabricated. Assistive devices can be combined with each other in the form of grooves, and PLA (Poly Lactic Acid) is used as a material. In the first experiment, 10 examiners operated the tube 15° in the caudad direction and 15° in the anterior direction, and measured it with a protractor to conduct a reproducibility experiment. Second, two examiners acquired vertically incidence images using the existing law method and assistive devices, and measured the distance between each measurement point to evaluate the reproducibility. The tube center ray angle reproducibility experiment was not statistically significant, but the angle difference was up to 9° between examiners. The reproducibility experiment of radiographic images was not statistically significant with the conventional method, and the method using an assistive device was statistically significant. Therefore, regardless of skill level, an image capable of securing reproducibility, which is the advantage of vertical incidence, could be obtained.

The white cane, walking assistive device of visually impaired person, has disadvantages for acquiring the information by contacting obstacles directly and detecting low obstacle on the ground. Recently, new devices have been developing to solve these problems, but these were not widely used due to high price and appearance. Therefore, in this study, we developed two types of walking assistive shoes which were manufactured with infrared sensors, pressure sensors and vibrating motors. Two types of shoes were classified with single sensor (SS) and double sensor (DS) type according to the number of infrared sensor. To evaluate the effectiveness, we compared required time and number of collisions during walking with walking assistive shoes and white cane on obstacle area. As the results, required time was increased than white cane while number of collisions was decreased when walking with developed walking assistive shoes. In addition, required time and number of collisions was more reduced when using walking assistive device than white cane. Therefore, we suggests that developed walking assistive shoes can a great help to provide safe walking condition and reducing time to adapt new types of walking assistive shoes.
