In order to compare the development performance of headed reinforcing bar and straight reinforcing bar in tension for steel fiber reinforced concrete (SFRC), pullout test of specimens with reinforcing bar which was anchored on simple beam perpendicularly was conducted. The experimental variables were steel fiber volume ratio ($V_{Rsf}$), concrete compressive strength, and existence of head. As the result of test, splitting failure of concrete in the development direction of reinforcing bar in most specimens was observed. For development detail of headed reinforcing deformation bar, specimens with 1% $V_{Rsf}$ showed approximately 63%~119% increase in pullout strength compare to specimens with 0% $V_{Rsf}$. Test result shows that SFRC is more effective in increasing pullout strength for headed reinforcing bars than increasing pullout strength of straight bars.

The beauty is like the bubble of beer, and behavior scholars have been regarded as worthless to study. As a result, the aesthetic in construction projects has resulted in underestimation or neglect. The fundamental cause of this result is that it is not easy to estimate the value of the aesthetic. The hedonic calculus by Bentham has a possibility to valuating the intangible or invisible goods. In this context, this study proposes a method to valuate architectural aesthetic based on the hedonic calculus by Bentham. As a precondition for suggesting the valuation method, this study defined the architectural aesthetic as the value of attraction that affects the value of the built environment. As the concept of beauty that conforms to the architectural aesthetic, it has established the concept of beauty as 'the phenomenon of combining the foreground and background of Hartmann'. In addition, the scope of the value measurement is defined as 'built environment' so as to include not only the building but also the surrounding environment. We have reinterpreted the seven dimension of the hedonic calculus proposed by Bentham and systematized the method of valuation of the architectural esthetic based on the seven dimension. The result of this study is meaningful in that it presents a new perspective and approach to architectural aesthetic. And it will be used as grounds for valuation and analytical approach to architectural aesthetic and will be used as a basis for expanding the field of study from aesthetic to value.

In this study, we have investigated the maximum smoke density and the initial stage smoke density in order to see the characteristics of smoke release of the architectural surface materials and the architectural adhesives, using smoke density chamber. As a result of the study, polyurethane foam showed the highest smoke density index, 206.55 within 10 min. In the case of the other samples, reinforced styrofoam was followed as 39.90, general styrofoam 33.73, and glass fiber 5.40, respectively. In the intial stage of a fire, it is forecasted actually to give hardship at the clear visibility. In the case of architectural adhesives, the highest ranking was those for windows and doors 509.64, stone 275.63, wood 232.25, tile 18.65, and styrofoam 6.44 were followed, respectively. This result is an early research to show characteristics of smoke release through experiment. However, it is meaningful that this study can be used as a basic for further study on architectural fire hazard prediction.

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.

The purpose of this study is to address the Issues on Architectural Plagiarism through the analysis of the discourses written in texts form. This study selected 60 texts of 20 suspected pairs of architectural plagiarism to derive key-words and key-passages to understand the Issues on Architectural Plagiarism. As a result, the Issues on Architectural Plagiarism are categorized into six different topics; Prototype, Archetype, Motif, Expression of Idea, Commodification, and Westernized-modernization. Meanwhile, the six issues were not discussed independently, but several issues were considered simultaneously in individual cases. This study is the first step to establish the objective guideline to judge Architectural Plagiarism and to be a basis in Architectural Plagiarism research.

Under the WTO system, global standardization of professionalism in architecture practice calls for transformation of curriculum in architectural education in Korea. This paper compares the curriculum standards of international accrediting authorities such as NAAB and RIBA based on UIA accord which defines fundamental knowledge and abilities of an architect. As a result this paper extracts 51 achievement oriented criteria of architectural education in Korea. It can be categorized as communication, design, cultural context(history and theory, human behavior and social aspects), technical systems(structural systems, environmental control systems, construction material and assemblies) and practice(project process, project economics and business management, laws and regulations). Based on this recommended Korean curriculum standards, current curriculum is analyzed focusing on the 5 architectural programs in Seoul. Through this analysis, it became clear that some area - social and economic aspects in architecture, sustainability in architecture, understanding and selection of construction material, assemblies and environmental control system, recycling of existing building, professional liability, professional rules of conduct, project economics and project management - need to be covered and emphasized to meet the international standards in professional education in architecture. The result in this paper will be used as a basic data in the process of finding the direction of restructuring curriculum for professional architectural education in Korea.

This study aims to verify a method for accurately estimating the sizes of the column, slab, and beam members of concrete structures using the impact echo method, which is a nondestructive testing method. The concrete specimens are designed and fabricated with six single-layer frame specimens composed of columns, slabs, and beam members based on three strengths of 24, 30, and 40 MPa. To estimate the sizes of the members according to the member types of concrete structures, the experiment was performed using the impact echo method. As a result of estimating the sizes of the concrete column members using the impact echo method, the error rate is 2.9%. As a result of estimating the depth of the concrete beam members, the error rate is 9.7%. And, as a result of estimating the thickness of the concrete slab members, the error rate is 2.4%. These results confirmed that quality control of the members of concrete structures is possible by estimating their sizes using a non-destructive testing method.

It is the juristocracy in architecture to judge the architectural plagiarism by copyright law. The architectural plagiarism should judge by architectural criticism. From the point of the criticism to discuss architectural plagiarism, the study on artistic imitation should be preceding. The current discussion on architectural plagiarism doesn't consider artistic imitation. Therefore, the result of the discussion only focused on whether the building is plagiarizing or not. From the point of architectural criticism, there should be three considerations, which are creation, imitation, and plagiarism. In the study of Aesthetics, it theorized artistic imitation as the appropriation. With the understanding of the appropriation, contemporary art is developing the discourse on plagiarism beyond the boundary of plagiarism fundamentalism. The purpose of this study is to apply the appropriation to the discussion of architectural plagiarism. The study introduces the discourse on architectural plagiarism rather than judging it with copyright law. There so the study categorized the aesthetics standard of appropriation art, then apply it to the architecture cases. The architecture cases subjects of analysis are the glasshouse by Philip Johnson, National Museum of Australia by Howard Raggatt, and the Meiquan 22nd Century in China. At the point of the appropriation theory, the glasshouse is the only architectural appropriation, and others need to apply the evaluation criteria of plagiarism.

Kengo Kuma used to be very known well as a critic before being an architect. He usually mentioned quite unique type of comments for subjects whenever his criticism, also even his works results have been able to be targets of criticism materials by his method. His works are the achievements of challenges based on his continuous dynamic criticism. Hence, to have well understanding of his architectural thinking and works result, his complexes criticism structure must be needed to understand. And also, this study is using 'KJ Method' type to analyze his architectural thinking which is complicated making by a type of non-linear. Kengo Kuma's structures of architectural thinking and critiques perspective of modern architecture have been created by 'KJ Method'. Critiques types of keywords and consequences words collected from among the local dedicated professional architecture books to get this research result. First of all, Kengo Kuma desired even modern architecture problems to be melt as a specific architecture result such as modern type of power structure. To have result, Kengo Kuma had experienced sensible activity through materials which have specific characteristic. Also place of materiality created to get relationship between environments and architecture. Secondly, he wanted to recover troubled traditional Japanese architectural perspective which blocked relationship by dichotomy as a right way. In conclusion, this research reaches Kengo Kuma's type of architecture which strongly emphasizes harmony among related components such as human being, materials, substances based on accepted natural environments and lives' principle. Also, much more specific methods have been derived by related works results analyzing which have similar characteristic as Kengo Kuma's one.
