This study investigated perceived discomforts and those reasons of the young and middle-aged, the aged, the disabled and the pregnant in various daily activities, and elicited universal design factors based on human capacities (physical, sensory, cognitive and affective). A total of eighty people (twenty subjects for each user group) participated in one-to-one interviews about thirty six items of daily activities. A degree of discomfort of the daily activities was measured using Borg's CR10 scale. As a result, the disabled and the pregnant complained about almost all of the daily activities, and their degrees of discomforts were significantly higher than those of the youth and middle-aged and the aged. However, the youth and middle-aged and the aged only complained about some specific items. The major reasons of discomforts were related to physical and affective capabilities in general, where the detailed reasons of each user group were comparatively different. Finally, the universal design factors were elicited for each daily activity item based on the results of each user group. This study can be used to understand the discomforts and characteristics of the aged, the disabled and the pregnant in the various daily activities. The universal design factors elicited can also be applied to design related products and facilities universally.

Although the national government prepares and implements planning for securing various services and facilities based on the needs of welfare centers for leisure of the aged according to the increase of life expectancy. These efforts are still beyond the satisfaction for the needs of the aged. These efforts are only polling on in terms of the increase in quantity, and so therefore there is total lack of high level of welfare facilities for the aged with regard to the consumers' characteristics and behavior attitudes. Under these considerations, this study aims at investigating through indoor space check list, the reality of whether the present welfare centers for the aged are designed with the application of the characteristics and behavior attitudes of the aged to the indoor space. The results of this study are going to be utilized as basic materials for future designs that may consider the behavioral attitudes of the aged and be able to increase their quality of leisure and welfare when building welfare centers for the aged in the future.

Medical color graphic research will serve as the basis for globally expanding and disseminating the design quality of the company's products through the era of production of medical robots. This study was based on technologies and contents suitable for the era of medical robot bed expansion, universal medical color application, ergonomic color, etc. In addition, the medical bed robot's color research direction was presented from the perspective of universal design. Accordingly, a universal color design was proposed, taking the functions of a medical robot under development by a domestic company as an example. The characteristics of this robot bed can be divided into three types of functions: first, treatment characteristics for prevention of pressure ulcers with curative, second, automatic seat exchange with cleanliness for medical environment, and third, Convenient, which can implement patient transport. The main idea is to present a combination of functional colors appropriate for this. The resulting color analysis and universal color design techniques could be a useful methodology for illustrating the appearance and function of a modern medical robot bed.

This study identified the experiences that the disabled actually feel in the library space in the face of growing social demands for spatial functions in public libraries. This study also tried to determine the requirements for the space that disabled wanted. For the research, 15 subjects were selected for each of the five people who were blind, deaf, and handicapped with experience using the library and individual in-depth interviews were conducted for the research. The study found that the experience of the disabled in the library space differed by type of disability and generally more negative experiences were found than positive ones. Misperception about the disabled of library staff and the non-disabled were having a significant impact on the disabled's negative experience for library space. There were a wide variety of opinions on the requirements for library space and there were generally negative perceptions about the current level of library space for the Integrated library service space.

Recently, personal mobility has been spreading and using increasing, but the pedestrian environment is getting worse and accidents are also rapidly increasing. Therefore, this study conducts a status survey related to the elements of pedestrian disturbances in personal mobility and identifies the problems. The following measures are presented to improve the pedestrian environment for the mobility handicapped through expert opinion surveys. The movement of individual mobility means in the walking space is prohibited, and the speed limit shall be stipulated to enable the mobility handicapped to walk safely and conveniently. Parking spaces will have to create obstacle zones in the parking area next to the roadway or at the border of sidewalks and roads, and regulations are needed to collect illegally parked vehicles. It is necessary to switch from the existing automobile-oriented road to the road structure considering the use of low and medium-speed vehicles.

This thesis is about how to let people be aware of the importance to raise awareness of the safety by offering User-center guide line instead of staff-center guide line. That's why it is important to make clear and be aware of how to prevent and how to cope with accident because it can lead to casualties which might be a tragic. For all that the guide for the fire accident is posted on the web site of each metro administration without any standard of information or coherence. Therefore it is urgent to make and provide new User-center guideline and to make it better we need to keep the following principles. First of all, the principles of Universal design should be applied to all the User-center guide line for fire accident at the subway station based on the comprehension of public design. Secondly, every metro administration need more communication to organize one coherence in designing instead of unilateral advertisement. Lastly, campaigns and training should be expanded in everyday life, so the citizen can raise awareness of the accident by themselves.

After the death of Min-sik Kim in Asan, South Chungcheong Province in September 2019, awareness of the school zone has been increasing, and the traffic law is being revised continuously. However, despite these efforts, the number of traffic accidents among children has not decreased significantly. This indicates the need for a new direction considering the behavioral characteristics of children and the traffic environment. Therefore, this study identified the current status and problems of school zones through case analysis of school zones in Korea. In addition, we analyzed the Vision Zero policy, the concept of Home Zone, and engineering-oriented road design cases and operation methods in Sweden, an advanced country in traffic safety. In addition, the cases of the two countries were compared and organized focusing on the basic principles of disaster prevention design. The purpose of this study is to suggest the direction of design and policy to improve school zone problems in Korea. Through this, it is expected that the results of this study will be used as data for future research development for the reduction of school zone fatalities in Korea.
