This study explores the typology of the urban detached houses in the new housing quarters that were created in the process of Seoul's urbanization in the aftermath of the Korean War. It analyzes and compares the urban tissue and space allocation set when the new urban residential areas were organized according to different methods of production. Based on the comparative analysis of housing built in the same time of 1960s, this study aims to deduce why a specific urban detached housing type was selected as an influential housing prototype and how this spread in later generations. Case study sites selected for this study include: the new Urban Hanok towns of Yongdu-dong, filled with mass Urban Hanoks built by housing developers; the single-family detached housing district of Myunmok-dong, filled with individual dwellings built by private builders; and the housing complex of detached houses in Suyu-dong, developed by government-sponsorship during the early 1960s. Each case examines the following: first, the difference in housing typology allocation according to urban tissue; second, the difference in spatial composition and arrangement within plots. As a result, it was found that differences in typology occur depending on which of the social, cultural, economic and technical factors was preferentially considered in forming urban tissue and allocating buildings in each residential area.

The purpose of this study was to explore behaviors of spatial usages such as patterns of spatial usages, perception on residential spaces, and furniture arrangement. A questionnaire survey and interview were adopted in this study, and 146 residents living in apartment with 3 bedrooms, stairway access, and 3-bay style in the City of Gwangju. The major findings of this study were that 1) dining-kitchen (DK) was conceived and used as a space not only for dining but also family gathering and guest reception. Dining table without refrigerator was frequently found in furniture arrangement of DK, and refrigerator has been relocated in utility room facing DK. The results imply the need for social interaction that has been growing. Anbang (master bedroom) has been perceived and used as couples' private area, aside from the traditional function of family interaction. A coordination of both bed and wardrobe out of different furniture arrangements was popular in anbang. Living room was used as a multi-purpose room carrying out various activities such as family gathering, guest reception, and housekeeping. Sofa and cabinet were the most common furniture arrangement in living room. The research results are a basis for development residential open housing system.

The goals of healthcare design based on the human rights to manage physically, psychologically, and emotionally healthy life. The healthcare designs, however, have been criticized not to reflect their primary users, patients' and families' needs, under the management strategy centered by the functional efficiency. The study focused on the patients' room design on the users' perspective. The design criteria for the patients' room in Japan, Germany, Australia, U.S. and Korea were examined and compared. The subjects of analysis are the floor plans of general hospital recently planned and built in Korea and Japan and the standard floor plan models proposed by prior studies in Korea and AusHFG in Australia. Results and conclusions are as follows: (1) the patients' room has developed as a place where the users manage their living during inpatient period and has become a private room. (2) The guidelines for patients' room size in Korea and Japan are not enough considering the users' diverse activities compare to those in U.S. and Australia. (3) The guidelines of Korea should be reconsidered for the users' comfortable lives. It must include the specific criteria of the enough space between beds, the storages, and other assistant tools and facilities. (4) The desirable types of patients' rooms by the numbers of users in Korea are proposed as a one-bed room type and a four-bed room type.

The study aims to find out the changing aspects of contemporary Korean libraries so called public in terms of their spatial configuration. In so doing, it analysed 14 recently built libraries by investigation of user's behavior. Interview and observation were conducted as a method of investigation. The method of analysis was based on statistics by mapping spatial data. As the result, it could be said that most users have a clear goal in Korea. In some libraries, the distinct characteristics of behavior show that users visit other functional rooms including functional rooms for the purpose. It could be said that the configuration of space in recently public libraries become more public as a place. In view of domestic affairs, in terms of users need, the reading room for personal study have features of the most private room and a static activity. so that the reading room separate from the other functional rooms in floor, but it adjoin other functional rooms in the horizontal configuration. so its location make offset a role of functional rooms can be interactive with each other, except reading room.

Cellular automata (CA) based cryptosystem has been studied for almost three decades, yet most of previously reported researches focus on the symmetric key encryption schemes. Up to now, few CA based public key encryption scheme has been proposed. To fill the gap, in this paper, we propose a new public key encryption scheme based on layered cellular automata (LCA). Specifically, in the proposed scheme, based on the T-shaped neighborhood structure, we combine four one-dimensional reversible CAs (set as the private key) to form the transition rules of a two-dimension CA, where the two-dimension CA is set as the corresponding public key. Based on the hardness assumption of the Decisional Dependent CA problem in LCA, we formally prove the proposed scheme is indistinguishably secure against the chosen-plaintext attack (IND-CPA). In addition, we also use a numeric example to demonstrate its feasibility. Finally, analysis of key space and time efficiency are also carried out along with RSA-1024, and the simulation results demonstrate that our proposed scheme is more efficient.

It is very active that existing companies of providing e-Learning contents try to differentiate themselves through a business model based on Web 2.0. For instance, Etoos, online education website (www.etoos.com) run by SK Communications has made more space where students can participate in the Web 2.0 era and overhauled its website completely, turning into an open-ended one, which strengthens learning and fun in 2007. This study is to analyze the present state of e-Learning contents with representative e-learning sites for middle and high school students, to find that the development direction for next generation e-Learning lies in developing contents focusing on learners that can get effective feedback and drawing collective intelligence grounded on the essence of Web 2.0, and to suggest 'the project to form virtual private tutor community in e-Learning contents.'

After the period of the Three Kingdoms Korean transportation architecture had been changed from the characteristics of the administration organization supporting the kings ruling system and gradually the characteristics as transportation architecture had cleared and diversified in accordance with the functions and characteristics of it. With this it was found that Korean transportation architecture like YukSa(驛舍), ChamYuk(站驛), GaekSa(客舍), JinSa(津舍), DoSa(渡舍), WonWoo(院字), JuMak(酒幕) and etc. had been developed variously and the architectural characteristics had developed with the functions and characteristics of transportation architecture. Some of them ,for example YukSa, ChamYuk, GaekSa, JinSa, DoSa, had the characteristics of the government office, so they had fundamental dignity of Korean wooden architecture on tile roof. But the WonWoo which was used by all of the people from the king to the people, had the characteristics of half-government and half-private. And the space of WonWoo was divided by the social position, the sex and the difference of temperature between summer and winter. And it was mostly located at the place away from the haunts of men, the form of it was the mud wall hut of the straw-thatched cottage like Sinhyewon of Mungyungsaejae and it was different from the station building of the characteristics of government office.
