The underground space which has been highlighted anew in view of urban scenery and environmental conservation through the control of ground development and solution of urban problems through making the utility of urban space efficient can promote the urban service, amenity, stability and others by arranging the urban function of ground area to the underground which is anticipated to be demanding the more in the future an also can be effective measures of confrontation in the solution of traffic, the complex in the heart of the city and lack of land through effective construction of the structure of urban space. But it has been understood to be extremely negative space at this time as limited to negative and fragmentary development and it has faced the necessity of constructing pleasant environment by overcoming every problem. After all, through the general research of underground space, this dissertation is reconsidering the development value of environmental design on the basis of the case study in international city development of underground space, and trying to extract design factors which should be treated in developing the underground space by establishing the evaluation model on the functional, techinical and behavioral elements factors.

It is important issue how to evaluate the economic feasibility of computing factors in the real world when we build ubiquitous spaces. In this paper, we propose a simple model that can evaluate the economic feasibility of mobile RFID-based ubiquitous computing system which enables seamless communication between offline and online via embedded computing factors in the real world. To achieve this, we explore the meaning of mobile RFID system, the difference between our research and extant researches concerning the evaluation of economic feasibility in RFID system, and propose the so-called 'Tag-based Evaluation Model' (TEM) which is an evaluation model to access the economic feasibility of mobile RFID systems. We also analyze the TEM via simulation cases based on proposed model and discuss the future of TEM.

This study aims at evaluating the characteristics and the preference on the sign design in the industrial heritages space. The research were performed by the process of literature review, case study, and survey of questionnaire. Seven industrial heritage space in Korea and China regenerated as art and cultural space after 2000 were selected and evaluated by 6 criteria including integrity, continuity, simplicity, aesthetics, legibility and historic aspects. The findings were the following. First, the six criteria factors were evaluated as the similar scores in the assessment of 7 sites without extremity. Simplicity was the highest score while historicality was the lowest one. It means that the characteristics of the sign systems of the heritage sites were focused on the simple, contemporary and effective design. Second, integrity, continuity, aesthetics, legibility were evaluated as the medium score in the sign design. While, in the evaluation on the aesthetics the score differences were comparatively high. Sanhai M50 which got the highest score showed the integrity of contrast using yellow and grey color with minimal design. However, Sanghai M50 got the lowest score in the historic aspects and was evaluated as the most favorite sign design in the preference. It means that the historic aspects have no direct relationship with the preference for the sign design. It shows that the effectiveness with integrity and the aesthetic aspects are considered more importantly than the application of the historic identity of the site in sign design.

The purposes of this study were to investigate the state of indoor thermal and air environment during winter in the one-room type multi-family houses occupied by university students and to analyze factors which influenced this environment. Field survey was conducted in 10 houses between 30th January, 2009 and 13th February, 2009 which measured indoor thermal and air elements as well kept records of interviews with residents and other related factors. Measured elements were air temperature, relative humidity, as well as concentrations of $CO_2$, CO, TVOC, and PM-10. The results can be summarized as follows. 1) The mean air temperature in each house ranged from 19.3 to $25.3^{\circ}C$, so most houses were not suitable for evaluation criteria($20-22^{\circ}C$). The average $CO_2$ concentration in each house was 965~3259ppm, so most houses exceeded evaluation criteria(1000ppm). The average TVOC concentration in each house were 0.00~1.17ppm, 5 houses exceeded evaluation criteria(0.12ppm). 2) Relative humidity, CO concentration, and PM-10 concentration were suitable for evaluation criteria. Therefore, indoor thermal and air environment during winter in one-room type multi-family housing occupied by university students was found to be generally uncomfortable. Important factor which were found to influence air temperature and the concentration of $CO_2$ were smaller space capacity than general house. Other factors which were found to influence the environment of these houses were the existence of a balcony as well as factors relating to the behavior of occupants such whether or not heating were operated, whether windows were opened, whether fans used, whether occupants smoked or used cosmetics, and whether the space was dusted.

As serving people's activities, pedestrian road systems are basic and necessary facilities in urban structure. To provide and utilize these pedestrian road systems in residential area would enhance urban environment as well as quality of life. For this reason, pedestrian road should be planned by consideration of people's activity in residential area. Evaluation of existing pedestrian road should be also oriented how people use it and what people do in it. This study amis to investigate functions of pedestrian road system throughout evaluation of user's satisfaction in order to improve better pedestrian road system in residential area. The purposes of this study are to analyze components of factors affecting on user's satisfaction, and to find the relationship among affecting factors. For this study, the on-site questionnaire method was applied to 267 individuals who were collected as the study areas where locate Toyogaoka and Kaidori, Japan. The collected data were clarified exploratory factors, and analyzed relationship between the factors and satisfaction by applying quantitative statistical techniques for the mapping investigation, Mann-Whitney u-test, and correlation. The results of this study are follows. The pedestrian road system is more preferred than surroundings of vehicle roads in residential district area where maintains pedestrian road as open space. In addition, satisfactions of the pedestrian road for each purpose were highly evaluated, because of conformability and convenience for usage. Consequently, the pedestrian road which is secure and greening as an open space is well carried out for the living circulation of residents. It would suggest that pedestrian road have to be managed and planned not a function of circulation but an open space system.
