  • The Wooden Seated Amitabha Buddha Triad and Altarpiece have not been the subjects of definitive species identification and scientific analysis. In this study, visual investigation, portable X-ray fluorescence (p-XRF), species identification, and lacquer layer observations were carried out to determine the original materials and conservation status. Cracks, exfoliation and discoloration were detected during the visual investigation. The p-XRF data indicated that chrome oxide green, malachite, gold, cadmium red, cinnabar, minium, hematite, lead white, ink stick (Carbon), and copper were used for pigments and the coronet accessory. Tilia spp., Abies spp., and Pinus spp. were identified from both the Buddha Triad and Altarpiece. Finally, lacquer layer analyses of the base layer, lacquer layer, orange pigment layer, and gold leaf layer observed modern synthetic pigments likely used in previous conservation. As the Korean Cultural Heritage Charter and the International Charter for the Conservation and Restoration of Monuments and Sites clearly state that objects of cultural heritage must be conserved using their original materials, future conservation of these objects should utilize the data obtained in this study to employ traditional materials. Furthermore, a deterioration map diagnosis can be applied together with the obtained analysis data to understand the conservation status of and inform an appropriate and authentic conservation treatment for the Buddha Triad and Altarpiece.

  • Scientific analysis was conducted to identify the paint pigments used in the Buseoksa Josadang murals. optical microscopy(OM), X-ray fluorescence(XRF), XRF mapping, scanning electron microscopy-energy dispersive X-ray spectroscopy(SEM-EDS), and Raman spectroscopy were performed to examine the pigments. The results confirmed that the Josadang murals consist of two paint layers wherein the pigments were distinct for most colors. It was estimated that celadonite, white clay, red ochre, cinnabar and minium, synthetic green pigment containing tin and zinc paratacamite, or botallackite were used in the upper layer. In addition, bone white, celadonite, red ochre, azurite, cinnabar or vermilion, and gold were identified in the lower layer. In addition, as Zn and Sn were detected in the green pigments extracted from the top layer of the paint, it is believed that Josadang murals were repainted over the original paint layer at some point after the 17th century. In addition, white pigments containing calcium phosphate were found in all the colors in the bottom layer, which is the original paint layer. These results are significant because this is the first time that white pigments are found in Korean traditional paintings. Additionally, the information revealed about the pigments in this study will serve as areference for the pigments used in the Goryeo period.

  • The pigments composition and structure of the mural painting at Pongjongsa Kuknakjon is discussed. The structure of inner wall is consisited of Paint layer, Ground divided two layers of yellow and white pigments, Support. In case of outer wall, it is consisted of Paint layer, Ground divided three layers of yellow and green pigments, a layer mixed green pigments and paint layer, Support. As a result of compositon analysis of mural painting pigments at Pongjongsa Kuknakjon using Micro-area X-ray diffraction system, the red pigment on inner wall is consisted of Heamatite($Fe_2O_3$), Magnetite($Fe_3O_4$)of deep black pigment, and Chalcocite($Cu_2S$) of light black pigment. The white pigment on outer wall is consisted of Anglesite($PbSO_4$) and Atacamite($Cu_2CI(OH)_3$) of green pigment. We found out that natural pigments painted in the mural painting at Pongjongsa Kuknakjon has kept up its own color for a long time due to using the natural pigment not to artificial synthetic pigment.

  • This study conducted scientific analyses on eight objects of wooden lacquerware to understand the manufacturing techniques of wooden lacquerware in the late Joseon Dynasty. The results of lacquer layer analysis with a microscope and scanning electron microscopy-energy dispersive X-ray spectrometry revealed that most samples were composed of 1-3 lacquer layers. Moreover, a red-colored layer was found to be red ocher and cinnabar, and Fourier-transform infrared spectroscopy analysis was carried out to determine the components of the lacquer layer. The detected components were mostly lacquer and partially cashew shell nut liquid.

  • Examples for application of cultural properties using Infrared Reflectography System as method of investigation on mural paintings and letters are given. This work is carried out according to asking of examination on inner layer paintings and letters in order to conserve the mural paintings discovered in the course of repairing ancient architectures. It is difficult to find the inner layer paintings and fine decorative line, but we can be observed by using Infrared Reflectography System and thus these results can be used as original rebuilding and drawings of mural paintings. Also building-repairing year, building participant though the investigation of letters written on the roof wood can be known.

  • Growth of researches addressing cross-culture in international business is exponential. This article reviews the extant researches around the national culture and describes the various conceptualization of culture through discussion of some of popular models of national culture. This article presented some of the most important issues in international business surrounding globalization, especially convergence and divergence of cultures and cultural changes. Global rapid changes in international business environment request the reconsideration of the assumption of cultural stability and the simple view of culture, which tends to examine the static influence of a few cultural factors in isolation form other cultural factors and contextual elements. This paper identifies a valid cultural grouping and proposes the following typology of the possible methodologies in international business; Ethnological description, Use of proxies, Direct values inference, and Indirect values inference. Rather than selecting a single methodology, it appears to be more appropriate to use multi-method in the cross-cultural international business research. It has been shown that cultural change is intertwined with socioeconomic-institutional variables, and that these variables may also add to determine culture contemporarily. This paper also explained the dynamics of culture as multi-level, multi-layer constructs. According to this model, we may understand how the dynamic nature of culture conveys the top-down-bottom-up processes where one cultural level affects changes in other level of culture.

  • The Seated iron Vairocana Buddha statue of Dopiansa Temple, Cheolwon was designated National treasure No. 63, it is very important to rearch about Korean Buddha statue because it has an inscription on the back indicates that it was made in 865 A.D., the fifth year of the reign of King Gyeongmun(861-875) of Unified Silla(668-935), through the devoted faith of some 1,500 Buddhist followers of the Cheorwon-gun area. In this conservation treatment, for the Seated iron Vairocana Buddha statue of Dopiansa Temple, Cheolwon plating layer and cashew paint layer of the iron pedestal were removed and for the paint the Body of the Buddha, fake metal layer and plaster layer were removed, stabilizing treatment and coating treatment were done, and removal and restoration of earlobe which had been damaged and later was restored with plaster in the regilding in 1988, and the white hair on forehead was replaced with material of rock crystal, and conch-shaped hair damaged was restored on 35 spots.

  • The musical instruments displayed in Korean Museums consist of various materials such as wood, stone, metal, leather, and soil. As for instruments manufactured of organic materials, as time passed, they became damaged due to physical, chemical and biological effects. In order to restore these instruments, studies on the materials as well as the manufacturing techniques should be simultaneously conducted because of the characteristics of sound making instruments. In this study, 17th century Double bass were chosen as the model for the restoration study. The type of wood was identified and the finishing layer was analyzed. To investigate the finishing layer, the surface observation was conducted and the component analysis was also conducted by using both FT-IR and SEM-EDS. As a result, the species of wood were identified as the maple trees. In case of the finishing layer of it, the diluted Goma Lacca, a type of resin, with alcohol as the main solvent was covered for varnishing layer. These results were combined to determine the restoration of Double bass Maggini Giovanni Paolo varnishing layer and by this Violin was made.
