Interior finishing materials are known as main VOCs and formaldehyde emission sources in residential buildings. The interior finishing materials are usually comprised of several layers with different emission properties, which complicates the emission patterns of the finishing materials. Thus, experiments on composite finishing materials and each of layers are needed to understand the emission characteristics of interior finishing materials. Results indicate that composite finishing materials have the various emission characteristics according to compositions of the materials and kinds of contaminants. Mostly, the emission rates of composite materials are higher than that of the single layer materials. The main reason is assumed to be rapid diffusion of contaminants from the bottom layer material into the top layer material.

The present study aimed to find a way to create forms that can simultaneously meet several architectural requirements by applying generative design methods specifically focused on cellular automata. In other words, it is tried to find various forms of architecture that all have common features. Because of the useful features of cellular automata, we decided to use it to generate various forms, but make a relation between the discrete nature of cellular automata and the continuous nature of architecture, was the major problem of our project. To achieve this goal, three consecutive stages were designed. In the first stage, independent variables including the location of the building, the height of the building, and the building area were considered as the inputs of the model. In the second stage, after locating the building, the building's main shell was designed as a hidden geometry for the cellular automata and then the cellular automata were determined based on this shell. The main result of this research is establishing a logical relationship between the discrete geometry of the cellular automata and the continuous search space such that it creates various optimized forms. Although we specify the site plan of this project at Iran-Tehran, this research can be generalized to various design sites as well as different projects, allowing the architectsto alter the cell dimensions, cell density, etc., based on their opinion and project needs.

In this paper, parallel IT(inverse transform) architecture and IQ(inverse quantization) architecture with common operation unit for the H.264/AVC decoder are proposed. By using common operation unit, the area cost and computational complexity of IQ are reduced. In order to take four execution cycles to perform IT, the proposed IT architecture has parallel architecture with one horizontal DCT unit and four vertical DCT units. Furthermore, the execution cycles of the proposed architecture is reduced to five cycles by applying two state pipeline architecture. The proposed architecture is implemented to a single chip by using Magnachip 0.18um CMOS technology. The gate count of the proposed architecture is 14.3k at clock frequency of 13MHz and the area of proposed IQ is reduced 39.6% compared with the previous one. The experimental result shows that execution cycle the proposed architecture is about 49.09% higher than that of the previous one.

The 'Research report on the Korean architecture(韓國建築調査報告)' is the first investigation and research of the Korean architecture by Japanese researcher. This paper is about Sekino Tadashi's viewpoints of Korean architecture in the 'Research report on Korean architecture'. And the findings are as follows. The investigation of the Korean architecture by Sekino Tadashi was carried out in the concern about the relation between Japanese architecture and Asian architecture, shortly after the research of the history of Japanese architecture started. And following investigation and research about Korean architecture by Sekino Tadashi was mainly focusing on the ancient architecture which he estimated highly in the 'Research report on the Korean architecture'. When he observed each architecture himself, he estimated highly the ancient Korean architecture, of course. And also he estimated highly many architecture of the Koryo and the Chosun period. However, when he estimated Korean architecture as a whole, he had been strongly influenced in the prejudice about Korea in Japan of those days. But this is not originate in his individuality. History research reflects the historical situation that the researcher was placed. The viewpoints of Korean architecture in the 'Research report on the Korean architecture' was produced by the Korean recognition in Japan of those days.

In the study of Buddhist architecture before the Goryeo Dynasty, the analysis of sectarian viewpoints is one of the effective means. In the study of Buddhist architecture before the Goryeo Dynasty, analyzing from the point of view of a Buddhism sect is one of the effective means. Until now, compared to the importance of the Beopsang school before the Goryeo period in the field of research on the history of Buddhist architecture, research on its temples was the least compared to those of other denominations. In this study, as one of the studies on Beopsang school temples, Geumsansa(金山寺), Beopjusa(法住寺), and Donghwasa(桐華寺), which were built as the Jinpyo's Beopsang school temple in the late 8th century and maintained until the Goryeo Dynasty, were targeted. And I tried a rudimentary analysis on the building composition of those temples from the viewpoint of the beliefs and teachings of Beopsang school. This study is meaningful in that it is the first attempted study in the field of architectural history on the Buddhist temple of the Beopsang school, which led non-Zen sects of Buddhism along with the Hwaeom school until the Goryeo Dynasty.

A series of experiments covering lowest three natural frequencies of rolling coupled pitching were conducted to investigate liquid sloshing with low liquid depth. The test results show that the most violent liquid sloshing in rolling and pitching is located in the vicinity of the first order natural frequency (f1). When the excitation frequency of rolling and pitching is located between 0.98f1 and 1.113f1, roof-bursting phenomenon of liquid appeared, and the maximum impact pressure is at 1.09f1. When the external excitation frequency is at 1.113f1, the number of sloshing shocks decreases sharply. Furthermore, the space distribution of the impact pressure on the left bulkhead and the top bulkhead was analyzed. It is concluded that with low liquid filling, the impact load is greater near the free surface and the top of tank, and the impact position of the side bulkhead increases with the increasing of the frequency near the resonant frequency.

The ROK military has established the MND-AF (Ministry of National Defense- Architecture Framework) and is applying it when developing architecture for Enterprise (MND), Segment (component) and Solution (weapons and force support system). The AMM (Architecture Meta model) of the MND-AF supports the establishment of interoperability by systematizing the architecture information structure defined by the Architecture artifact, describing the relationship between data and also by liking reference models and Information technology standard, common components, and MND-Meta data. which are interoperability standards. However, the MND-AMM has insufficient linkage with the standards, which places constraints on applying interoperability standards when developing Solution architecture. This study suggests a logical data model (OV-7c) from the MND-Meta-data-based Architecture meta model that will enhance the application of MND meta data managed by the MND interoperability standard when developing Solution architecture.

This paper proposes a $16{\times}16$ and $32{\times}32$ inverse transform architecture for HEVC (High Efficiency Video Coding). HEVC large transform of $16{\times}16$ and $32{\times}32$ suffers from huge computational complexity. To resolve this problem, we proposed a new large inverse transform architecture based on hardware reuse. The processing element is optimized by exploiting fully recursive and regular butterfly structure. To achieve low area, the processing element is implemented by shifters and adders without multiplier. Implementation of the proposed 2-D inverse transform architecture in 0.18 ${\mu}m$ technology shows about 300 MHz frequency and 287 Kgates area, which can process 4K ($3840{\times}2160$)@ 30 fps image.
