In this paper, cognitive radio and simultaneous wireless information and power transfer (SWIPT) are effectively combined to design a spectrum-efficient and energy-efficient transmission paradigm. Specifically, a novel SWIPT-based primary-secondary cooperation model is proposed to increase the transmission rate of energy/spectrum constrained users. In the proposed model, a multi-antenna secondary user conducts simultaneous energy harvesting and information forwarding by means of power splitting (PS), and tries to maximize its own transmission rate under the premise of successfully assisting the data delivery of the primary user. After the problem formulation, joint power splitting and beamforming optimization algorithms for decode-and-forward and amplify-and-forward modes are presented, in which we obtain the optimal PS factor and beamforming vectors using a golden search method and dual methods. Simulation results show that the proposed SWIPTbased primary-secondary cooperation schemes can obtain a much higher level of performance than that of non-SWIPT cooperation and non-cooperation schemes.

The interior designs and architectures are definitely important to the disabled because it could improve their independence considerably. Although the design is meaningless if for each disabled's symptom is not considering, the research on design to support detail symptom of each disabled is insufficient. This paper studies the bathroom in house for the disabled of hemiplegia after a stroke. The bathrooms is important space that cause many unnecessary activities and accidents without carefulness. Study method makes framework through principle of universal design and feature of hemiplegia after a stroke. We visit three places where the disabled live in and used qualitative analysis. After checking the present condition of the bathroom, a request and necessity of the disabled through observation and semi-structured interview. According to the result of this study, the obstruction factors were increased when the disabled try to use both hands or to reach and pick up objects, to move and to assist the severe disabled in the bathroom. Finally this study suggests design guidelines based on principle of universal design and factors for better bathroom design for the disabled.

This study suggested a way to compose a flexible environment capable of meeting the needs of various users from the aged people to challenged people, and ordinary people by applying the concept of universal design. The purpose of this study was to develop a more convenient environment by deriving the best size and color for each subject and constructing a detailed design platform for each module. For this, the concept of universal design as well as the current bathroom designs were examined and various users were analyzed prior to developing the design. A virtual environment was prepared based on the results and its usability was evaluated in two phases with various users including the aged people, challenged people, and ordinary people. As a result, it received quite a favorable evaluation from users, over 90 out of 100 in average, which can be regarded as a proof that it is differentiated from existing bathrooms. This study may lead to the change in the paradigm of bathroom in residential space, development of safer and comfortable domestic environment, and the enhancement of the quality of healthy life through the development of a design platform for each module that provides new experiences to various users. It is hoped that these modular systems are continuously studied not only for bathrooms but also for various residential spaces where people can stay.

The Korean society is recently becoming the aging society at an unprecedentedly rapid speed. Following the increase of the older population, their needs for special care is also rocketing. However, due to the increase of working women, nuclear-families, and old persons living alone, new facilities for the elderly such as nursing home are urgently needed. Thus, many nursing homes for the elderly are also rapidly providing. It is needed to examine if such nursing homes are properly designed for the dependent elderly to live. This study was carried out by the field observation using a checking sheet with measuring and taking photograph. The subjects were 12 nursing homes which gave positive responses for walking through their facilities. The items for observing and measuring were made based on the regulation on improving the facilities for the disabled, the elderly, and the pregnant. Whether each item fits the regulation or not was examined. The 9 areas in each nursing home were examined : entrance, hallway and corridor, stair, elevator, ramp, bed room, shower and locker room, bathroom, and rest room. It was founded that many accessible-related items were met. However, many supportive-related items such as ones for the visual disabled, and many supportive-related and accessible-related ones for bathroom, shower room, and restroom were unmet. In the process of this research, it was founded that the tool for evaluating the design of nursing home in terms of universal design should be developed.

With the advent of the 4th Industrial Revolution, AI utilization capabilities are being emphasized in various industries, but AI education design and curriculum research as universal education is currently lacking. This study offers a design for universal AI education to further cultivate its use in universities. For the AI basic education design, a questionnaire was conducted for experts three times, and the reliability of the derived design contents was verified by reflecting the results. As a result, the main competencies for cultivating AI literacy were data literacy, AI understanding and utilization, and the main detailed areas derived were data structure understanding and processing, visualization, word cloud, public data utilization, and machine learning concept understanding and utilization. The educational design content derived through this study is expected to increase the value of competency-centered AI universal education in the future.

The objective of this research is not only making the planning guides regarding a small-scale residential remodeling but also examining closely the social roles of the interior design for the poor and the underprivileged class by analyzing the residential remodeling cases. The scope of research includes 40 remodeling houses free of charge which are broadcasted in the TV program 'Love House'. Taking in consideration the characteristics of users like parentless or single-parent families and families with disabled persons, this study uses the spatial approach, user's convenience approach and psychological problem solving approach, in terms of the methodology. In result of the analysis of their interior design, first of all, it is essential solving the problem of limited house space by comparison with the family number. Second, the universal design concept for the family with disabled persons(72.5%), old persons or children is strengthened guaranteeing privacy in small and old interior space. Third, the interior design is focused in increasing communication among family members, because mental and physical obstacle would obstruct accessibility among them. This research shows the importance of the interior design which makes wide social roles contributing to create "welfare society".
