Purpose: The purpose of this study was to determine the effect of simulation evacuation training improvement activity through wheelchair skill training. Methods: The study included 40 patients with early stroke who were randomly allocated to a wheelchair skill training group (Experimental group, n=20) and a general exercise group (Control group, n=20). Both groups performed the exercise 3 times a week for 3 weeks. Outcomes were assessed using Wheelchair Skills Test Skills Performance (WSTSP), Wheelchair Skills Test Skills Safety (WSTSS) and Wheelchair Propulsion Velocity (WPV). Results: After 3 weeks of training, both groups showed significantly improved WSTSP, WSTSS and WPV (p<.01 in both groups). However, the WSTSP, WSTSS and WPV in the experimental group were very significantly better than in the control group (p<.01). Conclusion: These findings indicate that wheelchair skill training may be effective at improving wheelchair skill ability and wheelchair propulsion velocity in stroke patients who cannot walk independently. Therefore, short-term wheelchair skill training could be useful for patient safety in simulated evacuation situations.

The purpose of this study was to analyze the reality of clothes-wearing among physically disabled women and propose trouser designs. As a research method, an in-depth interview method was adopted for 10 women in their 30s and 50s with lower limb disabilities who could wear trousers and use wheelchairs. The study results identified the following factors that should be considered in the design of trousers. First, a semi-casual design that could hide physical deficiencies, was not different from ready-made clothes and enabled various looks was desirable. Second, the proper material would have little transformation in the form, have remarkable durability and laundry fastness, two-directional stretch, and hide deficiencies with a sense of thickness and density. Third, an "L-frame" pattern in a sitting position, and a straight fit were desirable. Finally, pockets can impose pressure according to their form, size, position, and sewing method, highlighted the need for a sewing approach to minimize seams in the fabric. For adjustment, an elastic band would be a good choice in terms of type, length, position, and material as it could satisfy both the convenience of putting on and taking off and comfort in wearing at the same time. Decorative design details can also impose pressure according to a sense of thickness, which means that they should be avoided in parts that are close to the body or can impose pressure according to posture.

Recently, the number of unmanned stores is increasing due to COVID-19. In unmanned stores, payments are mainly made using kiosks, but some people with physical disabilities or people with disabilities who use wheelchairs are not easy to use it. Also, young children and the elderly are also having difficulty using new technologies such as kiosks as they get older. In this study, in order to compensate for these problems, we intend to design and implement a system capable of performing order by a speech recognition function as well as a visual system when a user interacts with a kiosk.

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.

In the case of medical facilities, the evacuation time is delayed due to the decrease in the number of people in the hallway and exits due to the increase in the width of evacuation by using mobile beds, wheelchairs, crutches, etc. Accordingly, it is considered to secure evacuation capacity to reduce evacuation time according to corridor width and exit width. Accordingly, we would like to compare the standards related to the evacuation capacity of medical facilities in Korea and NFPA, derive differences, and use evacuation simulations to compare evacuation times according to changes in corridor width and exit width. In Korea, it is calculated based on the floor area by use, but in the case of NFPA 101, the number of evacuation routes, stair width, corridor exit width, and two-way door width was stipulated depending on the number of people. Using evacuation simulation, efficient evacuation capacity is calculated according to the reduction of evacuation time by changing the width of the hallway, changing the width of the exit, the width of the corridor, and the width of the exit. The evacuation simulation is intended to be used to secure evacuation safety of domestic medical facilities by calculating the effective evacuation time reduction by changing the width of the hallway and exit.

This study was purposed to provide basic information on the correct application of a wheelchair's backrest angle by investigating the change in cardiopulmonary function according to backrest angle during propulsion. This study examined the effects of the wheelchair's backrest angle on the cardiopulmonary function by varying the angle to $0^{\circ}$, $10^{\circ}$ and $20^{\circ}$ with a propulsion velocity of 60 m/min. The experimental parameters were respiration rate, oxygen consumption rate and oxygen consumption rate/kg which were measured by a portable wireless oxygen consumption meter (COSMED, $K4b^2$). The results of the study were as follows: 1) There were no statistically significant differences in respiration rates due to changes in the wheelchair backrest angle (p>.05). 2) There were statistically significant differences in oxygen consumption rates due to changes in the wheelchair backrest angle (p<.05). 3) There were also statistically significant differences in the oxygen consumption rate/kg due to changes in the wheelchair backrest angle (p<.05). In conclusion, changes in the backrest angle of wheelchairs during propulsion influences oxygen consumption rates and heart rates, while respiration rates are not affected. Therefore, a training program for good seating and posture needs to be provided, and the wheelchair seating system should be equipped with the unadjustable-angle wheelchair to reduce the functional load on the cardiopulmonary system.

The purpose of this paper is to study and propose playground facilities for physically challenged children to cultivate adaptability in society and advances the opportunity of participate in physical exercise. This study carried out site investigations by visiting and inspecting various facilities: a recreational walking path for physically challenged people, a care facility for physically challenged children, a special school for physically challenged children, and "Madel Park", a private-use playground for physically challenged children. The result of the site investigation found that, overall, play facilities are difficult to use for physically challenged children. In addition, because park space is often small and narrow, children who are restricted to wheelchairs find it impossible to access such facilities. By carefully inspecting each of the facilities, the author found suitable elements to apply for outside play space. These elements include the introduction of an essential slope way to allow for safe movement, the provision of special seats which support the body to outside play equipment and the adaptation of treatment room instruments that assist balance to outdoor playground facilities. On the basis of the site investigation the interview and the indoor education program for physically challenged children the author completed an outside play program. Each item in this program was classified as belonging to either a "sense play" program or and "exercise play" program. Finally, the author designed suitable play equipment for physically challenged children corresponding to each item in the exercise programs in order to research the appropriateness of the equipment to its intended use. This research is the first step. From this point the author expects that specific applications will be developed through a practical space plan and sufficient clinical experiments involving use of the new equipment.

Senior centers in apartment complex have been provided since 1980 according to the Housing Act in Korea. Nowadays these senior centers are model leisure facility for the elderly. However there are no specific guidelines for space composition and usage in a senior center. This study examines the space composition and usage patterns of 16 senior centers in apartment complex, Jangyou New Town. The data were collected by means of an observation, measuring, and interviews. The results are ; 1) A senior center consisted of one living room and two rooms for men and women would be appropriate; A living room is for common activities and two rooms for casual resting of each gender. 2) A kitchen is mainly used for setting the table or making tea. Thus, the living-dining-kitchen type would be appropriate. 3) Many rest rooms are located outside of a senior center and unisex one. The restroom should be separated by gender and located within the senior center. Also, the width of all doors should be more than 80cm and the floor be flat. The grab bars should be installed near the fixtures in a restroom. 4) Design and location of the shoe shelf are not convenient for the elderly to use. It should be designed and arranged for the elderly to use conveniently. Also, space for canes, walkers or wheelchairs should be considered in entrance area.
