  • The purpose of this study is to research fabrics, colors, and arrangement of color in Jogak-bo which were developed during the late Chosun dynasty. It is expected that from the analysis of the number, distribution and arrangement of colors of Jogak-bo in the late Chosun we can suggest various color arrangements thoset can be applied to modern fashion are summarized as follows. First, as for the number of colors of Jogak-bo according to material, silk fabrics Jogak-bo used a variety of colors whereas hemp fabrics Jogak-bo mostly used one color showing contrast between silk fabrics Jogak-bo and hemp fabrics ones. Second, as for the distribution of colors of silk Jogak-bo and hemp fabrics ones, warm colors were used most frequently. On the other hand, fewer achromatic colors were used to silk fabrics Jogak-bo, and they were more applied to hemp fabrics Jogak-bo. As for the use of cold colors, fewer cold colors were applied to hemp fabrics Jogak-bo compared to silk fabrics Jogak-bo. Third, as for the arrangement of colors, various colors were used in silk fabrics Jogak-bo, but a single color or not more than 1 color was applied to hemp fabrics Jogak-bo. It well demonstrates brilliance and glamour of silk Jogak-bo and stability and unity of hemp fabrics Jogak-bo. As for the arrangement of colors of Jogak-bo, most of Jogak-bo showed contrasting colors and shades, and similar colors and shades were hardly found in silk fabrics Jogak-bo whereas they were frequently found in hemp fabrics Jogak-bo.

  • ZnBo이 첨가된 (Ba,Sr)$TiO_3$ 후막을 이용한 planner capacitor의 전기적 특성을 조사하였다. 후막은 알루미나 기판에 스크린 프린팅기법에 의해서 제작되었고 $1200^{\circ}C$의 온도에서 소결하였다. 출발 물질인 BST의 저온 소결을 위해서 ZnBO를 첨가하였다. ZnBO가 1, 3, 5 wt% 첨가된 경우 소결온도가 $1200^{\circ}C$의 낮은 온도에서 소결되는 것을 확인했으며 ZnBO의 첨가랑이 증가함에 따라서 유전율은 감소하고 유전손실는 증가 하는 현상이 나타났다. 1, 3, 5 wt%의 ZnBO가 첨가된 (Ba,Sr)$TiO_3$는 각각 756, 624, 554의 유전율를 보였다. 또한 ZnBO의 양이 증가함에 따라서 누설전류가 감소되는 것을 확인하였고, ZnBO의 첨가가 grain의 성장과 density가 증가되어 누설전류의 양이 감소하게 되는 것으로 분석되었다.

  • This study aims to investigate the architectural characteristics of the Da-bo stupa by examining the correlation among architectural languages and by studying the features of its architectural components and transitional changes shown in Da-bo stupa line drawings in Dunhuang Mogao Grottes. The results are as follows. 1st, the Da-bo stupa of Dunhuang faithfully follows the sutra of lotus, and although the form changes, the fundamental essence of Bo-tap-yong-chul and two seated Buddhas provided by the Gyun-bo-tap-pum in the sutra of lotus is consistent. 2nd, the pagoda body can be periodically divided into parasol, stupa, and royal palace types. The parasol type has an incomplete tower body, which makes distinguishing each of its architectural components difficult. The stupa type appeared between the early (AD 618-712) and middle (AD 766-835) Tang dynasty. It combines the form of Indian stupa type and East Asian wood structural architecture. The royal palace type, which appeared between the peak period of the Tang (713-765) and Sung Dynasties, shows the standardized pattern of the Da-bo stupa described as two seated Buddhas and Bo-tap-yong-chul. 3rd, the use of a stylobate does not appear in the early construction of Da-bo stupa, only in the later period, in the form of high pillars. Forms include many Su-mi-jwah and three-way stairways and Dab-do, but as time passes, the forms are simplified to the form of high pillars. 4th, the purpose of early Da-bo stupa was to provide space for Da-bo-yu-rae of Gyun-bo-tap-pum; hence, it did not have sangryoon(the top part). However, after it was influenced by general pagodas, sangryoon was established. Toward the Tang Dynasty, sangryoon has come to emphasize the forms of boryoon(nine wheels) or dome. However, this form is eventually simplified to only retain bo-joo(the orb).

  • The effect of Fe and BO3 doping on structure, thermal, and electrical properties of Li1+xFexTi2-x(PO4)3-y(BO3)y (x = 0.2, 0.5)-based glass and glass ceramics was investigated. In addition, their crystallization behavior during sintering and ionic conductivity were also investigated in terms of sintering temperature. FT-IR and XPS results indicated that Fe2+ and Fe3+ ions in Li1+xFexTi2-x(PO4)3-y(BO3)y glass worked as a network modifier (FeO6 octahedra) and also as a network former (FeO4 tetrahedra). In the case of the glass with low substitution of BO3, boron formed (PB)O4 network structure, while boron preferred BO3 triangles or B3O3 boroxol rings with increasing the BO3 content owing to boic oxide anomaly, which can result in an increased non-bridging oxygen. The glass transition temperature (GTT) and crystallization temperature (CT) was lowered as the BO3 substitution was increased, while Fe2+ lowered the GTT and raised the CT. The ionic conductivity of Li1+xFexTi2-x(PO4)3-y(BO3)y glass ceramics were 8.85×10-4 and 1.38×10-4S/cm for x = 0.2 and 0.5, respectively. The oxidation state of doped Fe and boric oxide anomaly were due to the enhanced lithium ion conductivity of glass ceramics.

  • In this study, we analyzed the changes in glucosinolate content and gene expression in TO1000DH3 and Early big seedling upon methyl jasmonate (MeJA) treatment. Analysis of glucosinolate contents after MeJA treatment at $200{\mu}M$ concentration showed that the total glucosinolate content increased by 1.3-1.5 fold in TO1000DH3 and 1.3-3.8 fold in Early big compared to those before treatment. Aliphatic glucosinolates, progoitrin and gluconapin, were detected only in TO1000DH3, and the changes in the content of neoglucobrassicin were the greatest at 48 hours after MeJA treatment in TO1000DH3 and Early big. The transcriptomic analysis showed that transcripts involved in stress or defense reactions, or those related to growth were specifically expressed in TO1000DH3, while transcripts related to nucleosides or ATP biosynthesis were specifically expressed in Early big. GO analysis on transcripts with more than two-fold change in expression upon MeJA treatment, corresponding to 12,020 transcripts in TO1000DH3 and 13,510 transcripts in Early big, showed that the expression of transcripts that react to stimulus and chemical increased in TO1000DH3 and Early big, while those related to single-organism and ribosome synthesis decreased. In particular, the expression increased for all transcripts related to indole glucosinolate biosynthesis, which is associated with increase in glucobrassicin and neoglucobrassicin contents. Upon MeJA treatment, the expression of AOP3 (Bo9g006220, Bo9g006240), TGG1 (Bo14804s010) increased only in TO1000DH3, while the expression of Dof1.1 (Bo5g008360), UGT74C1 (Bo4g177540), and GSL-OH (Bo4g173560, Bo4g173550, Bo4g173530) increased specifically in Early big.

  • The rare-earth orthoborate family, RM3(BO3)4 is known to be the most promising material for the microlaser host. To grow LaSc3(BO3)4 single crystal, the phase relation of the system LaBO3-ScBO3 was investigated by DTA method. LaSc(BO3)4 was the unique intermediate compound in the binary system the peritectic reaction point of which was 1495 ±2℃. Owing to the peritectic behavior of the compound, the crystal growth of the rare-earth Sc-borate was carried out by pulling from the melt-soultion of La1+xSc3-x(BO3)4. The optimal conditions for the growth of LaSc3(BO3)4 were determined by traditional CZ method : pulling speed 0.7mm/hr, rotation speed 7-10 rpm under reduction condition. Pt and Ir crucibles could be used for about 8-10 times of growth. The effect of thermal configurations on the temperature distribution was investigated. A special two-coordinate manipulator was made for the precise movement of thermocouples from the melt to the top of the furnace for several thermal configurations. The radial gradient on the melt surface depends strongly on the construction of the afterheater. On the other hand, the axial gradient was mainly propotional to both the opening degree of baffle plate and the mutual positions of crucible and heater.

  • Aiming at finding symbolistic meanings and characteristics of makeup in Chinese Beijing Opera("BO"), this study formulated a theoretical framework mainly from literature in the Symbolism and symbolistically analyzed materials related to BO makeup from literature, internet web pages and illustrated news concerning performing arts. Main objects to analyze are the characteristics of four main roles in BO and the patterns, symbols, ornaments and traditions of Beijing Opera facial makeup("BOFM"). Four main roles are Sheng, Tan, Ching and Chou, categorized by gender, age, social position and personality. The result to analyze symbolistic meanings and characteristics of makeups for the roles in BO are as follows: the patterns and colors of BOFM function as explanations to help audiences understand each role's personality and dramatic situations as well as provide hints about the development and ending of an opera: that is, BO makeup is a communicative intermediary between audiences and actors in BO. It tends to follow the stereotypes, which conventionally dress and exaggerate the characters of roles, and copy the traditional Chinese perception about colors. Thus, by the metaphysical and typical expression of BOFM, Chinese people have not been pursuing the realism in opera but applying BO makeup to a mutual communication method between audiences and performing artists as to share their collective cultural heritages and spirits. Threfore, BO makeup has been an interacting language between the two entities and grown within the history of BO as a beauty art to highlight a BO by its unique systems, ornaments and beauty.

  • We have fabricated (Ba,Sr)TiO3$TiO_3$ thick films doped with various amount of ZnBO dopants (1, 3, and 5 wt%) by screen printing method on the alumina substrates, which were sintered at the temperature below $1200^{\circ}C$. With increasing the amount of ZnBO dopants, the relative dielectric permittivity of ZnBO doped (Ba,Sr)$TiO_3$ was decreased, while loss tangent was increased. 1 wt% ZnBO doped (Ba,Sr)$TiO_3$ thick film has relative dielectric permittivity of 759 at 1 MHz, while 3 and 5 wt% of ZnBO doped (Ba,Sr)$TiO_3$ thick films have 624 and 554, respectively. By introducing ZnBO dopants to the (Ba,Sr)$TiO_3$ thick films, leakage current densities were decreased. The decreased leakage current with increasing ZnBO dopants can be explained by increased density and grain size of thick film on alumina substrate. We believe this decreased leakage current density probably come from the increased grain size and increased density.

  • Objectives In the later period of Choseon dynasty, korean pediatrics became a pivot part of medicine. SoAUiBang was the most important book in that era. DongEuiBoGam was the most widely read of all oriental medicine books and published in early days of the Choseon dynasty. Therefore, this comparative study on the prescription and formation of SoAUiBang and DongEuiBoGam could be a useful way to understand SoAUiBang's characteristics. Methods This study was based on SoAUiBang and DongEuiBoGam, two literatures of oriental medicine. Results 1. Formation of SoAUiBang had a similar aspect with that of DongEuiBoGam's and enlarged the area of pediatrics by featuring general medical books. However, its formation did not follow the DongEuiBoGam's, but had its unique formation. It tried to include all diseases of pediatrics in the system of DongEuiBoGam. Plus, smallpox and measles belonged to the epidemic diseases were excluded from the area of pediatrics. 2. Comparing SoAUiBang's prescription of some important diseases with DongEuiBoGam's, it was almost a prescription based on DongEuiBoGam's prescription. However, adjustment of herbs and dosages could not be found in any oriental medicine books including DongEuiBoGam. Conclusions SoAUiBang maintained the traditional Oriental medicine based on author's scholarly creativeness. In addition, it also inherited the lineage of medicine in Korea along with the pedigree of DongEuiBoGam. Therefore, SoAUiBang should be re-evaluated as a medicine book that opened a new field of pediatric and had great academic values.
