In this paper, we have performed a numerical calculation of the scattered electromagnetic field around the building to evaluate electromagnetic interference caused by the building in the TV frequency band. The relations between the exposed concrete area of a building wall and the magnitude of the reflected wave have been examined in the case that the electroagnetic wave absorbers partially cover the building wall. From the obtained scattered electromagnetic field, we have calculated the DU radio and the required reflection loss of the electromagnetic wave absorbers which attached on the building wall to protect TV ghost.

In this study, the correlation between the rheolog y parameter of fresh concrete and the rheology parameter of wet sieving mortar was analyzed for analyzing to possibility predicting the rheology parameter of fresh concrete. Through the experiment, the dynamic yield stress and plastic viscosity of concrete and wet sieving mortar show a direct proportional relationship, and the two data had a correlation. Therefore, it is thought that it is possible to predict the rheology parameter of fresh concrete through the rheology parameter of wet sieving mortar. However, in order to more accurately predict the rheology parameter of fresh concrete, it is need additional relationship analysis by collecting more rheology parameter data of fresh concrete and wet sieving mortar.

건축물 화재에서의 피난대책은 Passive 대책과 Active 대책으로 대별될 수 있다. Passive 대책은 수동적이고 소극적인 개념으로 공간적 구조체인 특성에 따라 건축법규에서 규율하고 있는데 반하여, Active 대책은 능동적이고 적극적인 개념의 설비적인 측면에 따라 소방법규에서 규율하고 있다. 따라서 양 법규간 피난기준이 상호 대체적 기능보다는 소방법규에서의 보완적 기능이 보다 더 강하다. 본 연구는 피난기준이 건축법규와 소방법규로 이원화되고 관련설비에 대한 설치기준이 관계법규에 혼재됨에 따라 양 법규간의 상호기능보다는 기준적용의 혼선, 기준간 충돌 등의 문제점을 도출하고 효율적이고 합리적인 피난기준 적용을 위한 대책방안을 제시하고자 한다.

BIM is a practical and economical technology used in the construction process. Despite the fact that BIM is widely used in the design and another stage before construction, it is not largely applied during the construction stage itself. However, it is important to opt for BIM during construction stage because there may occur a number of risks such as construction delay and increased construction costs. Therefore, the present paper contains the analysis of the model use, which is mainly applied to respond to the BMI RFI that represents an information requirement of construction site workers, by analysing the BMI RFI application at the construction site. In addition, there is an analysis of the way the derived model use affects the project goal aimed at the project success.

In this study, the correlation between the properties of concrete in the fresh state and the compressive strength of hardened concrete was analyzed. It was found that the compressive strength increased as the values of T500 and plastic viscosity increased. However, there is a relationship between T500, which is a qualitative method, and compressive strength, but it seems difficult to predict through this. However, the correlation between plastic viscosity and compressive strength appears to be high, and it is believed that compressive strength can be predicted, but more data will be collected in the future for additional analysis. I think this will be necessary.

This study is an architectural design thesis aimed at designing a building at the River Thames in London, which could float along the river and be anchored in the river, in terms of the concept of the sense of place. The process of the study was as follows. First, theoretical backgrounds of the concepts of sense of place, placelessness, and non-place were examined and the sense of place of River Thames was analyzed. Second, the architectural planning elements could be applied to architectural design in terms of the relationship between the place and architecture, form of architecture, and behaviors of peoples. Third, the architectural design concepts and programs were specified based on the planning elements and a cultural complex that floats on the River Thames in London, England was proposed. The focus of this study was the process of formation of a sense of place by the cognition of architecture and people's activity, and this study claimed that the sense of place could be materialized by the metaphorically inherent property of the architecture.

Green building certification is being implemented in various countries around the world for the purpose of securing sustainability and reducing energy use and carbon emissions. Korea has been implementing G-SEED, a green building certification, for buildings since 2002, but in foreign countries, the evaluation target has been expanded from buildings to neighborhood units, cities, and infrastructure. Therefore, the purpose of this study was to establish Korean green building certification system in terms of neighborhood scale. In order to make Korean certification scheme for neighborhood communities, three major international certification systems (BREEAM Communities, LEED-ND, and CASBEE-UD) were compared. Comparison was executed about definitions and goals, certification system and range, certification categories, and regulation relationship by literature review. Based on the results, the evaluation system proposal including the scope, subjects, and items for green building certification in Korea was proposed.

The Korean architect Chung Guyon(1945~2011) is the translator of the Korean edition of Gourna: A Tale of Two Villages(1969) written by the Egyptian architect Hassan Fathy(1900~89). This fact, along with the facts that Chung changed the topic of his graduation thesis(1983) for UPA no.6 in Paris and that he became a supporter of earth architecture after he returned to Korea in 1986, confirms that Chung was strongly influenced by Fathy's architecture in Gourna project. Therefore, the present paper aims at extracting didactic characteristics of Fathy's architecture from the book and comparing them with those of Chung's architecture. The categories of the characteristics extracted from the book (or his architectural activities in the Gourna project) are: clay/earth architecture; communicative and cooperative architecture; and critical stance towards society, and these are commonly found in Chung's architecture, too, not without differences from Fathy's owing to the gap between the two architects' contexts. Reviewing these characteristics, this paper argues that Fathy and Chung tried to improve society in each context, working as both architect and social activist.

Traditional Korean architecture and traditional ships maintained a close relationship with carpenters and tools because wood, the material, was common. This close relationship may have been from the time of ancient architecture and ancient ships. In previous studies, researchers proved the relationship between these two sides through historical records of traditional architecture and traditional ships. This study attempts to prove the structural association using existing remains. As a result, three structural similarities between traditional architecture and traditional ships could be found. First, the types of wood used are similar, and the tools and terms used are similar. Second, the method of distinguishing horizontal and vertical materials and the structure of wood and the method of forming wood are similar. Lastly, the ship carpenters mobilized for the construction of the palace mainly worked on long and curved materials such as the eaves and the ridge of a roof, because this was the work done when the ship was built. Therefore, it can be assumed that the roof structure they created resembles that of the ship.

As linear scheduling method has been used since 1929, Empire State Building linear schedule, it is being applied in various fields such as construction and manufacturing. When addressing concurrent critical path occurring on linear schedule of construction, the empirical researches stress the resource management which should be applied for optimizing work flow, flexible work productivity and continuos resource allocation. However, work relationships has been usually overlooked for making the linear schedule from existing network schedule. Therefore, this research analyze the previous researches related to linear scheduling model and then propose the method that can be applied for adopting the relationships of network schedule to the linear schedule.
