This paper aims to clarify the spatial form and functional transition of Korean traditional shop house in Maehwa marketplace, Uljin. The general form of Korean traditional shop house of Maehwa marketplace was the timbered house of the tin roof built in the 1960s. As the scale of a building being comparatively small-scale, building area is $60m^2$ and the yard was mainly made behind the building. When the spatial form of Korean traditional shop house is considered, the composition of 4 by 2 is most. And in the front of a building, the shop is located, and when the back of a building prepares a residence, integration of a sales function and a habitation function is seen. The shop of Korean traditional shop house is converted into living space by change of the function, and the position is the middle of a front of building. This is considered as what inherited the Korean lifestyle. And the last, Although it is not different from the appearance of the shop house of other areas, since there are few grades of the change in comparison, the extension situation of Korean traditional shop house is recognized as an example important for future research.

This paper presents a three-dimensional finite element method based structural analysis model for structural analysis of reinforced concrete high-rise buildings during construction. The model considered the time-dependency of the structural configuration and material properties as well as the effect of the construction rate and shoring stiffness. Uniaxial compression tests of young concrete within 28 days of age were conducted to establish the time-dependent compressive stress-strain relationship of concrete, which was then used as input parameters to the structural analysis model. In-situ tests of a RC high-rise building were conducted, the results of which were used for model verification. Good agreement between the test results and model predictions was achieved. At the end, a parametric study was conducted using the verified model. The results indicated that the floor position and construction rate had significant effect on the shore load, whereas the influence of the shore removal timing and shore stiffness have much smaller. It was also found that the floors are more prone to cracking during construction than is ultimate bending failure.

This study aims to empirically examine the relationship between building energy consumption and building and local factors in Seoul. Building energy issue is an important topic for low carbon and eco-friendly city development. Building physical, socio-economic and environmental factors effect to increasing or decreasing energy consumption. However, there are different characteristic in each area, and this kind of variable has a hierarchical structure. The multi-level model was used to consider the hierarchical structure of the variables. In this study, a multi-level model was applied to confirm the difference between areas. Spatial area is Seoul, Korea and the temporal scope is August, summer season. As the result, in Model 1 (Null Model), ICC is 0.817. This shows that the energy consumption differs by 8.174% due to factors at the Dong level. Model 2 (Random Intercept Model) suggests that building's physical factors and Average age, Household size and Land price in Dong level have significant effects on Building energy consumption. In Model 3 (Random Coefficient Model), random effect variables have intercepts and slopes to vary across groups. This study provides a perspective for policy makers that the building energy reduction policies to be applied for buildings should be differently applied on area. Furthermore, not only physical factors but also socio-economic and environmental factors are important when making energy reduction policy.

Many architects in the second machine age experiment on the movement in architectural design. They consider a movement as a flow of information and vector as well as the real motion. They express the movement in architectural design as nomad architecture, network city, rhizome, mutual transformation among building, environment and visitors, and form generation as the actualization of the virtual. It is partly the result of the philosophy of Deleuze and Bergson that a movement is just a duration as a difference of quality. It is because Deleuze explains that the realization of the virtual as a becoming is also the kind of movement. This study analyzes the method of expression of movement in architectural design in the second machine age. As a result, the movement in architectural design in the second machine age was expressed in two ways. One method is a territorialized movement that moves in the fixed trajectory and the other is a deterritorialized movement that moves in the random indeterminate trajectory.

As the living standard of citizens are improving and the demand for the quality of life is increasing, the demand for the facilities of welfare and convenience for varied ages rises. Besides, our residential environment is faced with the need for changing into the environment of integrated function of living, which holds health, leisure, culture, education, welfare, etc. Considering the present reality requiring the augment of welfare facilities due to our aging society, community integrated facilities are needed, which can contain welfare service for home-living citizens within residential circle and can accept diverse needs of residents. Accordingly, the study began in order to suggest a better direction for community integrated facilities' plan that considers all age brackets for aging society. The study is to figure out way of thinking what community space of 3 age cluster middle-age in the 30s~40s, preparatory senior citizen in the 50s and old age brackets in the 60s~70s. As methods for attaining the aim of this study, surveys of documents and questionnaire survey were simultaneously used. The result of the study, investigating the importance of a community among the members in the residential complex, showed that all the age groups have highly perceived its importance. All the age groups responded that leisure are important to the elderly. It indicates that importance of their social relations are within the residential environment and it proves that there is lack of facilities for leisure activities of residents in apartment house.

The purpose of this study is to analyze collaborative relationship between members of a building construction organization. For the analysis of collaborative relationship, this researcher collected data by conducting a questionnaire survey with members of three large building construction organizations for apartment housing. The analyzed contents of collaborative relationship were the 'frequency of communication between organizational members' and their 'reliability'. According to the analysis of communication network, construction managers had low frequency of communication, whereas those responsible for each area, like construction deputy managers, had high frequency of communication. It indicates that middle managers are at the center of communication related to construction work in construction organizations. According to the analysis of reliability network, construction managers showed highest reliability, and employees at the top level in an organizational map also showed high reliability. Since they generally have a lot of experience, are some older of age, and assume responsibility for work, they are considered to receive reliability from other organizational members. This study proved that it was possible to numerically express reliability of organizational members, which is an abstract concept, and analyze it. Therefore, it is expected that the analysis result will highly be likely to be used in the area of construction management.

본 연구에서는 양생온도변화에 따른 자기수축의 예측을 위하여 FA 및 SF를 치환한 시멘트모르타르를 대상으로 자기수축변화를 측정하고 이를 등가재령방법으로 해석하고자 하였다. 이를 위해 수화반응의 온도민감도를 고려하는 Ea의 변화에 따라 지수함수모델을 이용하여 자기수축 해석을 실시하였는데, 경화단계의 $E_a$를 이용할 경우 응결단계의 $E_a$를 사용한 경우보다 정확한 해석이 가능한 것으로 나타났는데, 이는 경화의 전단계에 걸친 수화의 온도민감도 영향을 반영한 $E_a$값에 기인된 결과로 사료된다.
