Iron oxides are the essential coloring oxides in traditional ceramic glazes. However, when Fe is involved in the coloration in the form of ions or colloids in glazes with low Fe content, it is difficult to identify the iron oxide phases. Generally, in many these glazes, Ca-rich minerals are observed by X-ray diffraction (XRD) or microscopic images, owing to their devitrification by the high Ca content. This study attempts to elucidate the correlation between the crystalline structure and coloration in the glazes while mainly focusing on neoformed Ca-rich minerals and Fe content. An experimental firing was carried out to produce tree ash glazes, with pine tree ash and Buyeo feldspar. In the case of oxidation glazes, the scanning electron microscopy (SEM) images and XRD patterns did not exhibit any Ca-rich crystals, and all the visible light reflectance spectra lines exhibited a similar shape. In contrast, the reduction glazes divided into blue glazes and other colored glazes according to the shapes of their reflectance spectra. It was confirmed that the influence of Ca-rich minerals on the glaze color was more pronounced than the blue color of the reduction glazes when the Ca and feldspar contents were sufficiently high and low, respectively, to form wollastonite. As the Ca content increased and the elemental composition of the reduction glazes changed, the neoformation of the Ca-rich minerals, such as wollastonite, anorthite, diopside, and akermanite was sequentially observed.

Just as culture is a collection of lifestyles, Cultural Properties is what is made over a long period of time and is left around us, whether it takes form or not. Many countries around the world have their own standards and are trying hard to preserve those with precious values. And in the case of Modern Architecture, because they are still in use In our daily lives and for the lack of recognition, they are continuously threatened during urban changes and developments. The purpose of the research is not to preserve Modern Architecture as done In the museum, but to seek a way for it to coexist with the changing environments of contemporary cities. Therefore, it is to recognize Modern Architecture as valuable assets, which expresses historicity in urban settings, and to seek the design characteristics of Modern Architecture. This is a process in order to find a new method for conservation of historicity. The result are as followings. Modern Architecture have their design characteristics and these can be applied as a design guideline. Therefore the form, material, and the colors of individual Modern Architecture can be analyzed so as to create a design guideline according to their styles. According to the analysis of Registered Cultural Properties in Seoul, they can be categorized into 6 uses and found the design characteristics of individual uses.

A meshless technique using the geometric conservation least-squares method (GC-LSM) was devised to discretize the governing equation of linear elasticity. Although the finite-element method is widely used for structural analysis, a meshless method was developed because of its advantages in a moving grid system. This work is the preliminary phase for developing a fully meshless-based fluid-structure interaction solver. In this study, Cauchy's momentum equation was discretized in strong form using GC-LSM for the structural domain, and the Newmark beta method was used for time integration. The solver was validated in 1D, 2D, and 3D benchmarking problems. Static and dynamic results were obtained. The results are more accurate than those of analytic solutions.

The purpose of this study is to critically review the repair works of Seokguram architecture and to search for its original form and space. Seokguram's architectural form has been transformed throughout three repair works. The first transformation occurred during the repair work of the Colonial Government in 1913-1915, and the second occurred during the repair work of the Colonial Government in 1920-1923. The repair work done by the Korean Government in 1961-1964 also caused a severe change in the architectural form and space of Seokguram architecture. The more the repair work was added to Seokguram, the more its original form flew away like a mirage. Through the three repair works, the spatial composition of Seokguram changed in the following directions: from ((front chamber + passageway) + main chamber) to (front chamber + (passageway + main chamber)) through the second repair work, from (front chamber + (passageway + main chamber)) to (front chamber + passageway + main chamber) through the last repair work. Although the compositional space hierarchy of Seokguram was maintained during the first repair work, the architectural form based on the dry method was changed to the form based on the wet method. The Korean government's repair work was a tragedy for the 'Seokguram conservation project' that the people who led the conservation process misunderstood the architectural nature of Seokguram.

최근 2008년 화재로 소실되었다가 복구된 숭례문(崇禮門)의 단청 문제가 제기되면서 문화재 보존에 있어서의 전통기술 적용 문제가 논쟁거리가 되었다. 본고에서는 문화재 보존에 있어서의 전통기술의 의미를 살펴보고자 하였다. 일반적으로 전통기술에 대한 이해는 기본적으로 '전통'에 대한 관념에 기초하고 있다. 전통은 '고정불변하는 존재'가 아니라 '계승 발전하는 존재'로 보아 '살아있는 존재'로 규정되며, 그에 따라 '무형문화재로서의 전통연행, 전통공예 등'은 '고정된 실체를 가지고 있지 않는 것'으로 규정하고 있으며, 그에 따라 문화재 보존의 기본원칙인 '원형 보존'에서 '원형'이라는 것이 무엇인지를 정확히 규정하기 어려운 존재로 보고 있다. 한국의 경우 이렇게 원형을 규정하기 어려운 '무형문화재로서의 전통기술'이 유형문화재의 보존현장에 적용될 때 그 개념이 명확히 하지 않음으로 인해 보존 현장에서 여러가지 문제를 야기하고 있다. '전통기술'의 적용범위와 한계에 대한 논의 없이 현장에 적용되기 때문이다. 즉 '전통재료'를 사용하여 '전통기술'로 수복을 하는 것이 허용되는 것은 어디까지이며 문화재의 보존에서 이것이 어떠한 의미를 갖는가에 대한 논의가 결여되어 있기 때문이다. 본고에서는 이러한 전통기술의 적응문제를 국제적인 보존원칙 변화 과정의 검토와 함께 고찰해 보았다. 이러한 고찰 결과 '무형문화재로서의 전통기술'의 보존도 중요하지만 '유형문화재에 남아 있는 기술', 더 나아가 '제작 당시의 기술을 담고 있는 원래의 재료 보존'이 더욱 중요한 문제라는 점이 고려되어야 한다는 점을 강조하고자 한다.
