In the process of industrialization of our country in 1970's, Korea's housing strategy has focused on housing supply. Rapid completion and supply of apartment house buildings have caused a problem of their early deterioration due to their poor quality. In 1987 Housing Construction Promotion Act, therefore, included new regulations on housing re-construction. In July 2001, other new regulations on remodeling apartment buildings were also included in the Act. Reconstruction and remodeling have been considered to deal with such problems. This study suggests an appraisal criteria if they can select reconstruction or remodeling method in conducting their apartment building project. At first, evaluation items should be selected by the criteria of function31ity and economical efficiency. Second, the selected item is screened by AHP and multi-criteria decision-making methods. The result of study shows that the owners of apartment units will be able to select reasonable alternatives through the suggested appraisal method

현재 국내외에서 해안가에 수심이 낮은 지역을 중심으로 대규모 매립공사를 수행하여 주택단지, 항만시설, 공업단지 및 공항부지 등으로 사용하고 있다. 매립재를 양질의 모래로 사용하는 경우 매립방법에 따라 매립토의 조밀정도는 다르나 어떠한 경우든 상당히 느슨하거나 중간정도 느슨한 상태로 존재한다. 이런한 느슨한 사질토는 지진 시 액상화 현상에 민감하고, 낮은 지지력 및 큰 즉시침하를 야기시킨다. 따라서 매립된 느슨한 사질토는 향후 시설될 구조물의 중요도에 따라 개량할 필요가 있다. 본 현장의 준설 매립된 사질토의 지반 개량에 적용된 동다짐의 시험시공중 pounder에 accelerometer를 설치하고 적외선 beam을 이용, 충격시의 pounder의 deccleration과 impact velocity를 측정하였다. 여기에서는 이들 실측치를 근거로 중량물체(pounder)의 동적 거동 및 충격시 과잉간극수압 변화를 살펴보았다.

Jeonam aims to cultivate Hanok Village as a lodging resource for tourism industry in rural areas. For the purpose, it invited eight models of the Hanok Village publicly and selected our model as the best. This study is to introduce the concepts and characteristics of the village, centering on the model developed by our research team and awarded by the local government. We develop and suggest eleven types of improved-type Hanok model that is to be distributed to each city and county. We compose the space which reflects needs of residents for modern living. And we focus on preservation of decorative beauty to make it a resource of tourism by creating beautiful view of Hanok and reduction of financial burden to activate its distribution. The Hanok developed in this study has a significant meaning as improved Hanok that can be suggested as a new model of rural area housing project.

This study aims to clarify the architectural characteristics of three houses of Choseon Exhibition. Exposition/exhibitions were thought to be a model for the world. It shows the real status of the development, and thinking with visions at that times; therefore, exhibited house models would be a good source for what to be considered for the ideal houses of that times. Through the study, we could find out as belows. 1. The houses exhibited conserved the sitting-on-floor living style, otherwise the most proposals for house improvement suggested a chair-and-table style because of its hygienic quality and integration of the life at home and at work(school, too). 2. The spacial scheme for-family prior over for-guest was emphasized, but models at the exhibition were structured with Japanese traditional spacial program, such as Jashiki(座敷), Kyakunoma(客の間) or Tsuginoma(次の間), which were all Tatami-floored. 3. Through this exhibition, it is clarified that the architectural society in colonial Korea also tried to improve the modern housings, not only direct reception of the developed proposals. These houses was planned with the acceptance of the locality, such like Ondol, a floor heating facility which the Japanese engineer improve the efficiency. 4. Also these exhibited houses became a start to recognize a house as a product, and spurred on commercialization. As the result, we could find out that these exhibited houses accepted the modern housing proposals selectively, and that even if the exhibitions shows the advance in usual these houses were planned with the very conservative notions.

Apartments, which are typical residential spaces, are reconstructed or remodeled according to aging. However, reconstruction or remodeling of apartment complexes or an individual building requires following relevant laws and policies and requires a lot of time. Therefore, there are cases where apartment residents choose remodeling that improves the living environment by renovating only the interior of their household. In order to improve the interior space of an apartment, various materials such as windows, toilets, walls, and floors are replaced, and lots of matters must be considered in this process. Several problems arise in the process of selecting a remodeling company and carrying out construction, and the problem must be resolved through owner's decision-making. This study analyzes the problems through the case of apartment interior remodeling and suggests ways to improve them.

Individual Vacuum Pressure Method (IVPM) is a soft ground improvement technique, in which a vacuum pressure can be directly applied to the vertical drain board to promote consolidation and to strengthen the soft ground. This method does not require surcharge loads, different to embankment or pre-loading method. In this study, the ground improvement efficiency of Individual Vacuum Pressure Method was estimated when suction pressure increases step by step(-20, -40, -60, -80kPa) with different periods. During Individual Vacuum Pressure Method process, surface settlement and pore pressure were monitored, and cone resistance as well as water content were also measured after the completion of Individual Vacuum Pressure Method treatment. From the results, optimum duration of each step of vacuum pressure was determined, and the settlement was calculated using FEM numerical analysis.

The purpose of this study was to analyze the housing tenure choice decisions of older households, with focus on the activity constraints of the householders. For analysis, the probit model based on the data of the householders over 55 years of age from the 2015 KLIPS data was implemented. The research findings indicate that the ownership choice probability decreases when the head of the household has activity or social activity constraints. If there is an activity restriction, it is considered that the possibility of self-residence will be low due to the increase in medical expenses, the possibility of participation in economic activities will be low, the possibility of early retirement will be high, and the income will decrease. Therefore, if the head of the household has a personal or social activity constraint, such case is more likely to be categorized as falling under the poor residential group. This result suggests that the activity constraint can be utilized as a useful index for the housing welfare policy considering physical vulnerability.

The purpose of this study is to investigate the modernity characteristics of the traditional housing in Seoul 1920s to 1930s setting the criterion for analyses based on a Korean architect, Park, Kil-Ryong 'Housing improvement theory' about 'the Housing Plan of the Middle Area in Choseon'. The architect Park, Kil-Ryong expressed 'Housing Improvement Theory' positively founded on having a deep knowledge of traditional architecture. At his early working stage in 1928, he announced 'Housing Improvement Theory' about 'the Housing Plan of the Middle Area in Choseon' from the paper titled 'An Inquiry into the Housing of the Middle Area in Choseon', It is inferred that his paper quite affected the modern changes of traditional housing of those days. As the results of the study, even though the main floored room still keeps the symbolical and central position in traditional housing, the size of that is designed to be smaller than before. The room on the opposite side is generally designed widely as the scope more than 2 'KAN' and shows the features of expansion and division according to functions. By interchanging the location of the kitchen, the inner room as the main living space souths in the front of the house. The kitchen is designed as fitting size and separated from the space of working, linking, setting the table, keeping things and others. The bathroom is built in the house and then connected to the corridor. Each space is effectively planned for the best location in the house as considering lightening and ventilation.

The purpose of this study is to examine the validity of recycled aggregates (RAs) as a substitute for Sand-Mat material for soft ground improvement in the housing site development. To evaluate the possibility of RAs as a substitute for sand mat material, first of all, the criteria and regulations related with the quality of lateral drain layer were collected and checked. Secondly, both of the properties of RAs were compared with the properties of natural sand for the lateral drain layer. The material properties related to coefficient of permeability, pressure at-rest state and so on satisfied most standards. On the basis of the test results, RAs were used to the construction site as lateral drain layer. Accordingly, if the quality of RAs can be managed well, the application of these RAs as lateral drain layer to replace natural sand was highly effective. Also, based on cost analysis of two materials, RAs are proved to be very competitive.

The purpose of this thesis is a searching out the characteristics of Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism and its influences on Korean modern dwellings especially in the time of 1930's. At the early stage of the colonial time($1905{\sim}1919$), the central corridor type Japanese dwellings were implanted into Korea for the Japanese official residences. The central corridor type Japanese dwelling was an urban modern dwelling compromised between Japanese style and western style and distinguished by an outer-court type plan, Japanese entrance hall, central corridor and western style reception room. After the 1920's the central corridor type Japanese dwellings have spreaded itself and became a prototype of a modern dwelling in Korea. The characteristics of the central corridor type Japanese dwellings have influenced on the Korean high class dwellings and Korean architects' proposals for modern dwelling in the time of 1930's. By the implantation and spread of the central corridor type Japanese dwellings, Korean modern dwellings at the same time have affected and undergone transformation. The aspects of transformation were ; The outbreaking of the Japanese style entrance and central corridor, the transformation of MaDang from the inner court with a function of circulation into the outer court garden with plants and the transformation of Korean dwellings from the rural inner court type into the urban outer court type. The central corridor type Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism makes function as a precedent of a modern urban dwelling to Korean and makes Korean dwellings transform from the rural inner court type into the urban outer court type.
