With the emergence of cloud computing, more and more sensitive user data are outsourced to remote storage servers. The privacy of users' access pattern to the data should be protected to prevent un-trusted storage servers from inferring users' private information or launching stealthy attacks. Meanwhile, the privacy protection schemes should be efficient as cloud users often use thin client devices to access the data. In this paper, we propose a lightweight scheme to protect the privacy of data access pattern. Comparing with existing state-of-the-art solutions, our scheme incurs less communication and computational overhead, requires significantly less storage space at the user side, while consuming similar storage space at the server. Rigorous proofs and extensive evaluations have been conducted to show that the proposed scheme can hide the data access pattern effectively in the long run after a reasonable number of accesses have been made.

The final purpose of this study is to develop the synthetic and logical analytical tool for analyzing spatial organization of housing. For this purpose, this study made the starting-point by proposing some alternatives to improve one of the quantitative analytical tools of spatial organizations, Space Syntax. These propositions were intended to consider human behavior as well as physical structure in analyzing spatial organization. The propositions were as follow; 1) Classify the private outdoor space in detail, 2) Consider that the spatial organization which visitors cognize can differ from which residents do, and 3) Use distinctive spatial depth according to the states of connection.

The purpose of this study was to provide the fundamental data for the effective housing remodeling plan. Through the questionnaire survey, the actual conditions of remodeling in apartment housing were investigated. And as the result of statistic analysis, the relationships between characteristics of remodeling and building life-cycle, and family life-stage, were found out. The major findings of this study are as follows; 1) Most of apartment residents have remodeled the family living space and private living space. In detail, they performed remodeling frequently the change of finishing materials, facilities and equipments, and the change of the location of curtain wall ＆ storage fixtures. 2) It might be predicted that the building life-cycle was influential variable to predict apartment residents' remodeling. Therefore, in planning the support service for the remodeling, the building life-cycle should be taken into consideration.

This studies is the typological study to classify the characteristics of Floor plan in wooden house that is built in the suburb of Korea through case studies. For this type classification, I took several criteria as follows: number of floors, location of entrance, approach way to inner room, location of step, arrangement way of public space and private space, those are considered as important elements for the determination of Floor plan. Ive got 10 representative types by analysing and synthesizing the relationship between these elements. I expect that these study results would be good materials for the developing new model of wooden houses that is more proper to our life.

The purpose of this study was to analyze the view of housing of Korean and Japanese female university students. The view of housing was investigated in four stages-housing consciousness, resident opinion, ideal housing and housing needs-in this study. The data was collected through the self-entry questionnaire designed for this study and the sample of 400 in total, 200 cases form Korea and 200 cases form Japan. The results are as follows : The major findings of the housing consciousness were that Japanese female university students preferred the detached in the future. The resident opinion of Korean and Japanese female university students showed that the group space was more important than the private space. In the ideal image, they wanted psychological and physical comfort from their houses. In the housing needs, Korean have considered the distance of friend and family and been satisfied with interior design, whereas Japanese have considered the expression of social level and been satisfied with outdoor design.

Modern architecture after enlightenment period of Korea has been defamed indifferently before preparing devices for preservation. Many modern architecture has been underestimated by the feeling of being cultural victimized for Japan and economic logic. Other advanced countries make laws for their historic heritage with a concept for past-present-future. Also they re-create their cultural heritage to help their local economic. As the Registration System is established at july 2001, we have to find organic, positive interior space utilization methods about modern architecture. Modern architecture is private property in real using but it has historic trace. Therefore, modern architecture can be affirmative social property because it is a base of historic, cultural circumstances for local identity. The purpose of this study is to construct preservation and utilization methods of interior space for modern architecture.

The design concept of this dental clinic Interior design is emotional color expression for the medical facility. This dental clinic is showing off the new adoption of the Korean primary traditional color pallette for the medical interior design. The graphic wall of the corridor is strongly attracting the eyes of customers while wrapping the corridor wall and partition with rather unconventional primary colored graphic shaping a tooth. Also the vivid and the dynamic atmosphere are emphasized by using the red color in the treatment area and the powder room. For the space programing, I focused on the functionality of each space and the efficiency of the traffic line. Centering around the information desk, the principal traffic line Is divided Into the staffs' private movement and the public movement.

A pilot study on indoor air concentrations of nitrogen dioxide $(NO_2)$ was undertaken in the Seoul area, Korea dudring February-April 1986. Indoor and outdoor data on nitrogen dioxide concentrations were obtained for 48 private residences. Personal exposure to $NO_2$ was also investigated. Indoor outdoor ratio of $NO_2$ concentrations was 0.87, while the correlations between the indoor and outdoor levels were less than 0.50 for $NO_2$. Homes with an unvented space heater had average living room $NO_2$ concentrations approximately double those with a vented space heater. Residences with smokers have significantly higher living room $NO_2$ levels than those without smokers.

The purpose of this study was to analyze the characteristic of planning of Living-Hanok which bases on inherited and developed traditional lifestyle in Jeon-Nam province. After that arranged the characteristic in order which was divided by 9 items such as pattern of developed Hanok, type of floor plan, structure, pattern of using inside space, number of bedroom, the exist of private bathroom in the each bedroom or not, number of bathroom, the exist of storage space in the house or not, style of entrance and the exist of Utility Room or not. Additional, there was interview with resident who have been lived in Living-Hanok since after completion due to investigate resident's concerning of the Hanok. As a result, the last goal of analyze and interview is to presentation of more developed planing factors for Living-Hanok.

The purpose of this survey was to find out the actual conditions of living and housing needs of three generation family in the sharing apartment houses in Sang-Gye area. 1. General family type was one which is living with single parent (female), middle-aged couple and their children togeter. 2. Their main mobility to move in this houses was because of the special design of sharing apartment houses. 3. Most of actual dwelling activities of old parents and middle aged couple were performed in condition of space-integration except a few activities. 4. The "Space-compromise type" was proved as the most ideal type of three generation sharing house in our country. In which, private spaces (such as bed rooms and bath rooms) are planned to be used seperately, public spaces (such as living room and dining room) together. 5. It would be better if massionette type was taken in the case of more than 30 pyung (net area).net area).
