This study has the purpose to reveal the differences of residents' using behaviors of living facilities at 3 complexes. The physical characteristics of the complexes have been investigated by a literature study and field survey. In addition, questionnaires were answered by residents on living facilities using behavior on community environment. The tools of analysis are frequency, percentage, and cross tabulation using SPSS WIN 12.0 program. Followings are the results of the study. 1) The developmental concept of 3 complexes maintained its initial identity. (1) The residence-oriented complex, having wider residential space, had better downtown access and more convenient facilities for daily life. (2) The residence-government mixed complex, constructed with an eco-friendly concept, had wider green and public service space and good downtown access but on the other hand, had less convenience facilities because of a short period from construction. (3) The residence-industry mixed complex, located in sub-urbanity and conceding more land for industries, had poor access to downtown but had more convenient facilities for workers' use. 2) The most frequently visited convenience facilities were shopping facilities, large or small, and banks, and activities were commonly done in the complex or adjacent area. This means it is recommended that the developer of the new complex locate convenience facilities in multi-core concentration types or street types rather than one-core concentration types.

In this paper, we construct an efficient fuzzy identity-based encryption scheme in the random oracle model. The fuzzy identity-based encryption is an extension of identity-based encryption schemes where a user's public key is represented as his identity. Our construction requires constant number of bilinear map operations for decryption and the size of private key is small compared with the previous fuzzy identity-based encryption of Sahai-Waters. We also presents that our fuzzy identity-based encryption can be converted to attribute-based encryption schemes.

In urban space, public space is publicly or privately owned space freely accessible by the public. Privately owned public space to the public hosts small-scale rest facilities to serve the public in buildings of certain purposes and sizes for the sake of pleasant urban environment. The Building Act and building ordinances formulate a set of criteria for management and easement of construction standards as well as the area. When creating privately owned public space, one can get incentives through the easement of floor space index and height limit. The purposes of this study were to investigate and analyze privately owned public open space, which is freely accessible by the public, and its adjacent streets and to propose plans to improve the regulations for securing privately owned public space for more rational and practical legal applications. The study then proposed some plans to help to increase the quality of privately owned public space including applying the coefficient to suggest the type of privately owned public space fit for the features of the streets and measure the appropriate utility level differently and distinguishing the mandatory items according to the facility regulations in privately owned public space from the ones qualified for additional points in case of installation. The types of privately owned public open space should be applied differently and the content of facilities intended should be different according to whether it will serve as a resting place or grant more importance on traffic by walking, depending on the features of its adjacent streets. The privately owned public space, the frontage space of building, and the adjacent sidewalks should become a whole and be regarded as one space from the integrated perspective. The results of the study claim further significance in that it investigated privately owned open space and roadside across Seoul. They will serve as useful data to solve the problems with the privately owned public space of the city, which destroys spatial continuity by focusing on the quantitative increase of privately owned open space and creating individual privately owned open spaces and builds high-rise buildings alienated from the existing spaces, and to increase the quality of future privately owned public space.

As people's interest in the increase of individual leisure time and health grows, their interest in sports is also growing day by day to improve their standards of living. In the midst of the social changes, people's awareness of the disabled's sports activities is changing as well. However, the disabled's full access to public sports centers is restricted due to the shortage of facilities, area and available programs in public sports centers including community gymnasiums. In order to solve this problem, rehabilitation sports centers have been built as part of public sports centers, but the number of rehabilitation sports centers is still small. Besides, the disabled find themselves uncomfortable when using rehabilitation sports centers because most of them are outdated and too small in size. To make matters worse, sports centers for the use of the disabled only have a negative effect on the disabled's making inroads into society by hampering them from being a part of social unification. This study made a comparative analysis on the areal state of indoor gyms and swimming pools, which are the main areal factors of rehabilitation sports centers and public sports centers. Based on this analysis, this study aims to propose a sports center use plan for both the disabled and non-disabled. As a result, the total floor area ratios of indoor gyms for the disabled were found to be higher than those of public sports centers. This is because many indoor gyms for the disabled are not well equipped with resting areas, auxiliary or supporting areas. Regarding swimming pools for the disabled, their total floor area ratios and areas were found to be lower than those of public sports centers because, in many cases, these swimming pools are used for the rehabilitation of the disabled in rehabilitation sports centers. For this reason, swimming area for individual leisure activity or hobby is insufficient.

This study investigates supply patterns and residential characteristics of the Urban-type Housing in Seoul. There have been 3,336 buildings and 71,790 housing units approved until the end of 2012. One-room apartments and small units less than 30 $m^2$ of residential area amount to 81% and 82% of total units, respectively. Major findings are as follows. First, single- and two-person households less than 30 years of age are mostly lived in the housing. Respondents are mainly professional and white-collar (43%) and service and sales workers (27%). Most of them are mid-income classes (67%), which is twice more than that of single- and two-person households in Seoul. They pay 672 thousand won in rent more than average rent of mid-income class. The rent to income ratios are 29.9% for single households and 24.5% for two-person households, which are higher than that of mid-income bracket. Third, their satisfaction level is relatively high in internal environment and access to public service facilities, but not in external environment and community service facilities. They are satisfied with security and daylight, walking and safety, access to public transport and parking space, but not with noise and vibration, natural environment, access to park and cultural and sports facilities, and most community service facilities. It is necessary to reexamine the articles of deregulation and prepare design standards while considering different housing and locational types.

School is where students spend a lot of time. However, it is made up spaces which have got no consideration for students. Public buildings, such as schools, were designed by experts, not by users, while the opinions of users were reflected in a small part. As a result, school has become an uncomfortable place for students. User participation design has been proposed as a way to improve it. Recently, in designing schools, user participation design called "School Space Innovation Project" has been carried out actively and many kinds of guidelines have been suggested in project. But because it is unsystematic, In fact, it is hard to apply on site. Comparing and analyzing various User Participation Processes to figure out the similarities and differences is the purpose of this research and we want to suggest the result as a data that can be used as guidelines for project related to User Participation Design.

The primary purposes of this study are to suggest a medium-sized regeneration project which includes the excluded small sites near existing regeneration site, to identify urban improvement type which fits local conditions, and to suggest proper regeneration strategies for the improvement type. Main findings of this study are follows. First, the size of the living environment improvement project in urban area should be larger than 3ha and government's incentives are required for parcel merges to make the medium-size project site. Second, independent type of urban regeneration project should consider local characteristics while center-spread type of urban regeneration project should build a center by providing neighborhood facilities and proper housings. Third, urban regeneration project should be able to utilize local assets, such as cultural heritages, natural landscapes, transportation facilities. Fourth, standards for public support should be prepared to improve local competitiveness. Last, further studies are required for urban regeneration system improvement.

Recently, it is becoming increasingly difficult to ignore carbon emission implication of building operations due to the significant rate of energy usage in buildings. In the building sector, our normal expectation implies that large building floor area induces more greenhouse gas (GHG) emission. In this research, the correlation between building total floor areas and GHG emission was explored by simple linear regression and analyzing the yielded residuals for confirming this seemingly obvious conjecture. By looking at the generated regression lines drawn based on the data sets representing public facilities in Ontario, Canada, we were able to confirm that carbon emission rate shows a proportional increase or decrease depending on the total floor area of buildings as has been implied as a conjecture. Some buildings were found to emit significantly large and small amount of GHG, and we addressed potential reasons why those buildings show the deviation from the confirmed proportional interrelation between a building's total floor area and the amount of GHG emission.

The apartments of South Korea has developed enormously from 1960's to the present. Nevertheless, People have not paid much attention to the exterior colors used in the apartments. For this reason, this study tries to understand the differences of the colors between each brands and areas based on the newly-built apartments in Jeonju and Gunsan, and this focuses on the colors used in the main buildings, public facilities, playgrounds, and the main entrances. According to the research, although six-cases all showed that YR was higher than any other color patterns, but there were differences from both the brands and the areas. Both the colors and the materials, as distinguished by the brands, were more diverse in the apartments by the small or medium businesses than in those by the big businesses. Moreover, when the identical brands were observed in Jeonju and Gunsan, the differences between the areas was more recognizable than the differences between the brands. Both the colors and the materials, as distinguished by the areas, had more varieties in Gunsan than in Jeonju. It was because Gunsan had many diversities in natural, historical or social backgrounds, as compared to Jeonju. Unlike other studies, this study researched public facilities as well as the main buildings so that it was possible to perceive the harmony of the colors in the apartment complex; however, the cases used in this study were limited numerically.

This paper conducted a survey of residents and public officials for the projects to make smart-city plans of Geumsan-gun. In introduction, several domestic and foreign cases related to smart-city projects were Investigated. To initiate the smart-city project of Geumsan-gun, the local status of Geumsan-gun was investigated regarding various aspects of natural, social, urban environment and smart-city facilities. The results of this survey are as follows: Overall, more than half of survey respondents said they had satisfaction of their housing quality. Several problems in their residence areas, such as insufficient welfare systems, shortage of parking spaces, industrial infrastructure, were reported. Meanwhile, the survey result indicated that tourism and leisure facilities, health care support systems, industries promote the economy and job market of the area. An interview with public official is also important to select the relevant meaningful projects and regional issues. Three models for each spatial unit were proposed in Geumsan-gun based on the natural, agricultural, and geographical environment. In result, the three smart-city models are categorized as urban type(large area), complex city type(medium area), and smart village type(small area)
