  • Through analysing on construction cases of stupa built in A.D. 7,8th, I have researched about these : constructive methods of inner soil of stupa, spatial compositions, characteristics of structures, arrangements of inner soil and etc. And cases analysed are six ; Mireuksajiseoktap(stone pagoda of Mireuksa Temple site), Gameunsajisamcheumgseoktap(three storied stone pagoda of Gameunsa Temple site), Goseonsajisamcheungseoktap(three storied stone pagoda of Goseonsa Temple site), Wolseong nawolliocheungseoktap(five storied stone pagoda in Nawonri, Wolseong), Guksagokseoktap(three storied stone pagoda in Guksa valley), Giamgokseoktap(three storied stone pagoda in Giam valley). Additionally we researched about inner soil of Sacheonwangsaji tapji(basement of stone stupa site in Sacheonwang Temple site) to speculate on composition of Synthetically, the foundation could be divided as core space and outer space. ; the former as structural function and the latter as ornamental function. And the core area could be divided again as center column space and buffer space. The relationship between core spaces and its formation are as belows; First, according to the area of foundation and scale of stone pagoda, formations of core are differed. As the scale of stone pagoda goes bigger, and the area of foundation goes larger, the structure of stone pagoda comprised by center column type and layered-core which endure upper load independently. On the contrary, as the scale of stone pagoda goes smaller, and the area of foundation goes lesser, the structure of stone pagoda tend to use only center column to endure upper part. Second, spatial composition of core area is comprised as two spaces, one which endure upper load and buffer space which absorb side pressure and upper pressure. The buffer space tend to be used in case of those structures which could not endure side pressure or have lots of joint. In some cases, it was located below the cover stone of foundation and gained upper load. And in case that have not gained pressure from side stone, the buffer space are comprised by smalle stone or roof tile to get structural supplement.

  • This study is to investigate the effect of a domestic pottery stone as a batch inclusion on the synthesis of porcelain bodies and their physical properties. The basic composition of porcelain bodies studied was consisted of 50wt% kaolin, 25wt% feldspar and 25wt% quartz. The inclusion of pottery stone was performed by partial substitution for either quartz or feldspar up to 25% of the total weight of batches. Sixteen porcelain bodied different in batch composition were prepared by firing them in the temperature range from 110$0^{\circ}C$ to 135$0^{\circ}C$ and their physical properties and microstructures were carefully examined. It was found that the inclusion of pottery stone could reudce the firing temperature for vitrification up to 5$0^{\circ}C$ but appreciably decreased the mechanical strength of sintered bodies. The most faborable result could obtain with partial substitution for both quartz and feldspar at same time up to 25% of the total batch weight.

  • The purpose of this study was to investigate the association of twinkling artifacts according to the types of urinary stones in color Doppler ultrasound. For two types of urinary stones with different colors, the degree of occurrence of color Doppler twinkling artifact in water tank was analyzed, and the surface condition and composition of the stones were analyzed. The composition of Calcium and phosphorus were the most frequent components in white and brown stones excluding carbon and oxygen. Twinkling artifacts of color Doppler appear stronger in brown stone. The higher the phosphorus content of the stones, the shorter the twinkling artifact appears, so it is possible to predict the main composition of stones.

  • With biological organism brown pollutants layers are thickly formed on inner stone materials in Gyeongjuseokbinggo(Ice storage in Gyeongju). Some simples were taken from this layer and its chemical composition, mineral composition, salt and microstructures were analyzed. This study shows that the pollutants layer can be removed easily, because it attached softly in stone surface. But because of its serious weathering state the stone surface also can be removed during the removing process. The origins of brown layer are assumed to be the soil in the mound over the Seokbinggo and the coarse sandy soil in the entrance. For the preservation of the Seokbinggo Waterproof and replacement of the coarse sandy soil should take precedence over the remove works. Subsequently moistureproof works should be enforced.

  • Many knotted carpets from western China and Central Asia from 700 BCE to 700 CE demonstrate strong resemblances to the Assyrian-Persian stone reliefs and Hellenistic-Romanmosaics. Egypt reveals the earliest samples in plain linen fiber and carpets with colorful designs in the mural paintings. The Egyptian wall decoration in faience shows the motifs of waterlily in two variations in the design, both of which appear in the Assyrian floor thresholds designs. The same waterlily or four-petal design in the Egyptian and Assyrian stonework also appear in the Pazyryk knotted carpet in the same manner. The Assyrian thresholds show a composition with a central area and borders in a square or rectangular overall design, which again parallels the Pazyryk carpet. The ideas of composition and motifs commonly seen in the Hellenistic and Roman mosaics appear in the carpets of Central Asia and western China. The similarities between the stone mosaic works and carpets demonstrate clearly that the remote places and peoples in ancient times learned from, and exchanged with, each other the ideas and artistic styles, and integrated to create some local artistic traditions, thanks to the roles the easy-to-carry textiles played throughout the Silk Road. The carpets played their roles: as practical material for daily use, and as carrier of cultural information through their designs.

  • To comparison the surface treatment methods of stone board materials, the results of Dorry's abrasive test were 23.4 for water-jet system and 18.9 for flame-burner system. Therefore abrasive hardness, the stone board materials by the water-jet system was greater than one by flame-jet system. As a result of Shore's hardness test, the stone board materials by water-jet system was twice greater than one by flame-jet system. Authors carried out microscopic observation to survey a defection of the composition minerals for two methods, but all of the both methods have not founded a defection. Therefore, the stone board materials by water-jet system was greater durability than one by flame-jet for the surface treatment methods.

  • The aim of this study is to evaluate the diagnostic ability of dual-energy computed tomography (DECT) for Composition determination of urinary stones in phantom model. Seventeen cases with urinary stones who underwent DECT were enrolled in the study. The composition of the urinary stones was extracted from the seventeen patients were analyzed with DECT in phantom model with fresh pork. The volume scan method using Dual-energy software was used and the scanned image sets were assessed. All 17 urinary stones of the phantom model were analyzed according to the stone composition using DE stone Analysis were divided into uric acid stones (n=6, 35.29%) and non-uric acid stones (n=11, 64.71%). These urinary stones were pathologically confirmed. The mean attenuation values of uric acid stones at 135 kV, 100 kV and 80 kV was 348.87 ± 166.37 HU, 345.33 ± 151.18 HU and 337.94 ± 172.77 HU, respectively. The mean attenuation values of non-uric acid stones at 135 kV, 100 kV and 80 kV was 551.93 ± 297.09 HU, 747.04 ± 351.31 HU and 958.19 ± 424.72 HU, respectively. At 80 kV, uric acid stones and non-uric acid stones showed significant difference in the attenuation values(P<0.05). The attenuation values of DECT could differentiate the compositions of urinary stones between uric acid and non-uric acid stones at 80 kV in phantom model.

  • Structure and mucosubstance histochemistry in the epidermis of five teleostean species, i. e., spotty belly, Agrammus agrammus, devil stinger, Inimicus japonicus, stone fish, Erosa erosa, cubed snailfish, Liparis tessellatus, and Japanese bluefish, Scombrops boops were investigated. The epidermis of five species studied is composed of three layers: superficial, middle, and basal layer. The superficial layer is comprised of rather flattened cells. Mucous cells, the type commonly found in fishes are completely lacking in the epidermis of devil stinger, stone fish, and cubed snailfish. The epidermis of devil stinger and stone fish have multicellular glands which do not have mucosubstances. The skin surface of them is covered with mucous layer. The superficial cells in the epidermis of devil stinger, stone fish, and cubed snailfish are mucus-secreting cells. The composition and the amount of the mucosubstances vary in species and body regions. The mucous layer on the skin surface and superficial epidermal cells of devil stinger contain a mixture of neutral and acidic(sulfated and nonsulfated) mucosubstances. In stone fish, the mucous layer has acidic(sulfated and non-sulfated) mucin and the superficial epidermal cells contain neutral mucin. In cubed snailfish, the type of epidermal mucosubstances is identified as a mixture of neutral and acidic(non-sulfated) mucin. The mucous cells of the epidermis in spotty belly and Japanese bluefish contain neutral mucin.
