As success stories of using virtual reality (VR) have become more prevalent, interest in performance-related technology has rapidly increased around the world. Performances such as, Cirque du Soleil had much success in using video technology, these VR applications have enabled experiences using digital image technology. However, critics have claimed that the completeness and diversity of visual content is reduced, due to insufficient storylines, spatial composition, and partial use of the entire visual field. Therefore, the design of a performance using digital image technology should consider the characteristics of the production stage to be different from real world performances. In this study, the visual space of the stage, the method of creating space for the stage, and the movement of the performer and utilization of the performance was analyzed. Through this, It transferred the limitation of the traditional stage into the space and time of the image and opened the possibilities of the tran­-media.

portable white space device(WSD) obeying the Korean regulations of TV white space(TVWS) can cause harmful interference to a digital TV receiver residing at the same pixel around the edge of the digital TV service coverage for the case with a changed propagation environment. In order to solve this problem, we propose a method to allocate the resource of a hybrid WSD based on TVWS geo-location DB with spectrum sensing. Using the received power of digital TV signal through the spectrum sensing, a hybrid WSD can calculate the maximum permitted EIRP based on location probability. Based on the accurate allocation method proposed in this paper, it is possible to satisfy the Korean TVWS regulations and to eliminate the harmful interference to TV receivers nearby the hybrid WSD.

Recently, many people perform jobs including study and work within a common indoor space. Yet this space could have an adverse effect on operational efficiency as well as health because of many pollution factors. So maintaining a pleasant environment in the common space is important. In this thesis we study the integrated environment management system for better living conditions. This system analyzes and manages harmful environmental factors to make more pleasant environment in office, library or classroom. The proposed indoor environment management system will provide a pleasant environment by monitoring the indoor environment and driving the actuator in real time. In addition, it can be applicable to different types of indoor space to reach solutions to raise recognition of indoor environment pollution by people.

The purpose of this study is to identify the current state of coding education for children and to propose a new 'play-oriented' educational content to keep up with the problems of education in line with the revision process of the 4th Industrial Revolution. As a research method, we investigated and analyzed the case of the Korean early childhood coding education program, and then suggested the direction of the future infant coding education and suggested a new play area for children. Case analysis shows that current coding education places many restrictions on children's activities. So we propose a coding education space as a 'playing space' where children can actively play. Because the space is used, emotional education is possible because it can stimulate senses such as vision, touch and smell. In addition, this study is expected to cultivate not only spatial comprehension, but also imagination, creativity and cooperation. In future research, we will study the characteristics and technical process of children in-depth to help develop early childhood education.

This research studied the characteristics of the customer circulation in four department store food court restaurants located in Seoul. The characteristics of the customer circulation are the following: Before customers leave the dining space where they eat food, they come and go to spaces such as the water purifier space, the napkin storage, and the cup storage. On the other hand, they do not come and go from the dining space to the waste area or the area where used cups are returned. Therefore the spaces, that need to be located very near the dining space, are the water purifier space, the cup storage, and the napkin storage. The waste area does not have to be placed very near the dining area and the area where used cups are returned is not needed. A minority of customers drink water and use napkins after going to the waste area and the area where dirty dishes are kept. To prevent these customers from going against the circulation of the majority of customers, a water purifier space, a cup storage, and a napkin storage should be placed additionally connecting to the waste area and the area where dirty dishes are kept. For effective circulation plan and spatial composition of food court restaurants, these characteristics of customer circulation should be considered. It is not recommended to place the water purifier space, the napkin storage, and the cup storage, the waste area or the area where used cups are returned, and the hand cleansing facility in the same location just for the convenience of workers.

As life gets richer along with social development, the interest in composure of life and in quality of life gets higher. According to this, a concept on bathroom, which had been simply physiological sanitary space before, is being gradually changed, thereby being reborn as space of charging vitality of life and of realizing own desire. As these consumers' new desire is emerged, it is being highlighted the behavior of being made in space now called 'bathroom', the requirements for this space, and the interest in what aims to be pursued. However, current Korean people have different bathroom behavior such as using outside bathtub or filling a washbasin with water unlike the center on stand-up shower in the West, thereby having inconvenience. Accordingly, when bathroom is designed that reflects Korean people's bathroom behavior, the satisfaction with using bathroom will be able to be enhanced. This study aims to increase the use satisfaction with bathroom space, to survey Korean people's situations of using bathroom, the inconvenience in using, and the general emotion, and to elicit requirements for bathroom users and basic design guidelines available for reflecting the health in planning bathroom space, the space of solving sanitary problem, and the modern people's physical features and lifestyle.

This study aims to find out the present conditions of pilotis space, and the usage and requests of it by residents as to suggest the direction in planning pilotis spaces in apartment housing. This study selected six apartment complexes, and conducted case-studies and surveys of them. The study findings are as follows. 1) The types of pilotis spaces of the apartment housing can be categorized into an entry type, a community type, a recreational type, a bicycle storage type, a pedestrian passage type, a parking type, and a visual passage type. As a result of studying the present conditions, pilotis spaces of a recreational type were the most, and a community type and a parking type were not found. It was found that diverse types of pilotis spaces need to be planned in consideration of the characteristics of an apartment complex and its residents. 2) As for residents' time spent in using the pilotis space, they spent little time. This can be attributed to the fact that most pilotis spaces were designed only with simple flat benches, and gazebos, which seemingly failed to draw residents' attention. Therefore, the spaces need to be planned for diverse purposes after examining residents' needs, which can include indoor exercise equipments and children's play facilities. 3) Regarding the residents' requests about pilotis spaces in the apartment housing, the most widely requested was using it as a community space. Also, many requested to use it as a library, and a children's play space. Therefore, it needs to be considered to plan the pilotis space for providing diverse programs.

Rapid changes to the paradigm of smart media have created a communication environment through merging with various media such as IoT technology, which is internet of things. Among them, user' need for a start home, which is one of people living conditions, has been growing and values of the communication environment in a living space using a smart mirror have been growing. However, studies on figuring out behavior and analyzing needs of family members who actually use the living space are insufficient. This study is to draw the service system of the home smart mirror by analysis of behavior and needs of users of the living space. For a research method for analysis of behavior of family members, I wrote two kinds of user's experience maps, which are frequency of use of a quantitative space of a living space and space's important value scales by persona study and depth interview. Through this, applied spaces of the home smart mirror (living room, bathroom, powder room, dress room, porch, kitchen, room) and the types of user needs (type of providing information, entertainment type, control type, service type) have been drawn and statistical analysis methodology has been utilized for a research of user preferences in regard to correlation between living spaces and types of user needs based on a survey. As a result of analysis of ages and gender, types of user needs by space have been drawn and the service system of the home smart mirror has been drawn. It would be utilized as a basic material for various contents development and design using the smart mirror in the future.
