In this research, kinematic comparative analysis was performed on strokes of abscission and spinal cord injured athletes who participated in 2008 Beijing Paralympics wheelchair table tennis games. Strokes of all situations were collected under real match-like conditions. Among those, three major forehand stroke motions and backhand stroke motions were drawn Data collected by 9 infrared cameras were expressed in angular motions using graphic program LabVIEW7.0. As a result, forehand stroke of spin handicap athlete from analyzed images, the rotations of the trunk happened with the rotations of shoulder and the flexion extensions of elbow nearly at the same time. According to these results, insufficient turning force or speed of rackets is recompensed using flexion. backhand stroke of spin handicap athlete from analyzed images, the rotations of the trunk, the flexion extensions of the elbow and the flexion extensions of the shoulder were lined up on the prolongations of ping-pong balls. Forehand stroke of abscission athletes was done by outward rotation of the arm using backswing and inner rotation. As for backhand stroke, backswing was made by inner rotation in the spin of shoulder and waist. And after the backswing, impact was formed in wide outer rotation towards the ball.

This study was conducted to examine the effects of a smart home (electronic control unit, ECU) on the performance and satisfaction of activities of daily living of wheelchair users. A total of 15 wheelchair users (10 patients with spinal cord injury and 5 patients with stroke) were investigated. Smart homes were equipped with ECU technology, which consisted of automation of furniture and products. The products and facilities were integrated and controlled by a smart device or voice. Performance and satisfaction of activities of daily living were measured by the Canadian Occupational Performance Measure (COPM) before and after residence in a smart home. All participants showed a higher COPM (performance score ${\geq}3$, satisfaction score ${\geq}4$) during residence in a smart home compared to residence in the current home. In addition, the COPM scores differed significantly before and after residence in a smart home. These results provide evidence of the applicability of smart homes based on high technology. However, additional studies of more smart home participants should be conducted to improve the quality of the results.

This paper proposes architectural and evacuation recommendations through evacuation experiments of two child care centers with disabilities. To achieve these purposes, a survey on the architectural characteristics and evacuation experiments was carried out. The results were as follows: (1) the child care center with disabilities were located within one kilometer or five minutes from a fire station and 119 safety center, but the architectural characteristics and the ratio of self-moving children in a care center were very different conditions. (2) The evacuation behavior patterns of children with a disability were as follows: hugging a child by a teacher with the arms, walking with hugging and holding the child by a teacher, moving a wheelchair with a helper, and drag-out a cerebral palsied child with a mat wrapping. (3) The speed of the evacuation was fast in the following order: drag-out with a mat wrapping a child with a disability, hugging the child with the arms, walking with hugging and holding child, and moving with a wheelchair. In the case of difficulties in the vertical evacuation, a temporal evacuation area was essential for children with disability.

This study develops a sizing system of mass-customized male suits for wheelchair users. One hundred and three male wheelchair users' 21 anthropometric dimensions were measured to identify body shapes and develop a sizing system. The measured wheelchair users' body sizes were compared with the average body sizes of Korean males from the $6^{th}$ Korean Body Size Survey to understand the body size differences between two groups. As a result of body shape classification using the KS's Drop method, wheelchair user body shapes were classified into four shapes for upper-body (A: 32%, B: 26%, BB: 24%, and Y: 18%), and two shapes for lower-body (B: 70% and A: 30%). The upper-body of wheelchair users was relatively developed than Korean males; however, the lower-body was relatively stunted. The key dimensions of a sizing system were selected as chest circumference, waist circumference, and trunk length, outside leg length based on the correlation analysis between anthropometric measures. The top sizes were determined considering chest and waist circumferences for horizontal sizes, and additionally the trunk length was divided into short, medium, and long groups for vertical sizes. The bottom sizes were selected considering the waist and hip circumferences for horizontal sizes, and additionally their outside leg length was divided into short, medium, and long groups for vertical sizes.

This study investigated the degree of inconvenience in existing ready-made clothes and clothing preferences through a survey of 197 wheelchair-bound males in order to provide preliminary data for the development of a suit that considers the physical characteristics and requirements of the disabled in wheelchairs for improved quality of living and positive interpersonal relations. Among the survey respondents, the 30s to 40s age group was the largest at 71.6%. The most common type of disability was myelopathy at 72.6%. Also 59.9% of respondents had a job and ongoing external and social activities. As for the duration of wheelchair use, 10-20 years was the longest at 40.6%. It was found from the survey that respondents felt inconvenienced with existing clothes and changing pants was most inconvenient. Most experienced having their clothes altered due to the difficulty in finding well-fitting ones; consequently, the length of pants was the most altered item because pants are based on the size of a standing man and there exists a discrepancy in length due to the atrophy of the legs of the disabled. They preferred one style in general for clothing preferences as well as common design and details as well. However, they preferred a style with a short front and long back due to a discomfort in jacket length. A short length was the most complained about pants item.

Purpose: The diverse users and the increase of power wheelchair users have made it difficult to apply the standards of Wheelchair user accessible toilet rooms for the existing law and BF-certification. To address these issues, the standards of the relevant laws have been improved (Ministry of Health and Welfare, 2018), but there are still many problems. In this study, problems with the standards for Wheelchair user accessible toilet rooms in Korea are analyzed by comparing national and international standards. In addition, improvements to standards for Wheelchair user accessible toilet rooms will be suggested. Method: It presents improvement for standards of Wheelchair user accessible toilet rooms by comparing national, international standard and standards of many countries. Korean standard, International Standard(ISO 21542), American Standard(ADA Standards), German Standard(DIN 18040-1), Austrian Standard($\ddot{O}NORM$ B 1600) and Swiss Standard(Norm SIA 500) were investigated and analyzed. Results: Korea's standards differ from the ISO and the Standards of other countries in many ways, so there is a need for realignment. Specifications for disabled toilets and clear criteria for the size, shape, and location of sanitary appliances in toilets that are practically available to wheelchair users should be provided. Considering the increasing number of disabled toilet users, the installation of various disabled toilet rooms should be considered considering the user characteristics of those who can walk and wheelchair users. Implication: Recent partial improvements to relevant laws cannot meet the requirements of various users. Therefore, comprehensive and clear standard should be presented that take into account changing society and the environment.

The purpose of this study was to identify differences in records for each section of the wheelchair marathon and to provide information necessary for training and basic data for developing training methods. The subjects of this study were analyzed for the records of a total of 5 foreign male athletes and 4 domestic top athletes who completed the 42.195km full course among the participants at the 2016 Seoul International Wheelchair Marathon. Every 5km section records and finish records were used, and the first section to the ninth section were set. As for the data processing method, descriptive statistics (Mean, SD) were used using the statistical program SPSS 25.0. The following conclusions were drawn according to the above research methods and procedures. In the case of the winning W1 athletes, the record at 30km to 35km was the fastest 8 minutes and 43 seconds in the entire section, and the difference was 1 minute and 4 seconds compared to the K1 athletes of the nation's No. 1 athletes. In order to be ranked higher in international competitions, training to adapt to a quick pace at a later stage is required. That is, it was found that the second half face should be faster based on the half distance. In addition, in each section of the first half, it is necessary to develop a race pace suitable for the average speed level for each individual section. Therefore, it is considered that the fitness training program that can maintain the early race and the training program that can cope with changes in pace after the second half should be applied.
