  • We have investigated the feasibility of using cyclic ambident nucleophiles in s-triazine ring transformation reaction and found that they can replace the $N_{1}-C_{2-N_{3}$ fragment of s-triazine directly in basic conditions, yielding the corresponding bicyclic products. In this paper, we described the reaction and mechanistic aspects of s-triazine to pyrimidopyrimidine transformation by 6-aminouracil derivatives. This type of ring transformation is supposed to be first attempt that deals with the successful s-triazine to bicyclic heterocycle transformation.

  • In this paper, an experiment was done where the input device used the linear multiple regression and the sRGB color space to perform a color transformation. The output device used the GOG, GOGO and sRGB for the color transformation. After the input device underwent a color transformation, a $3\;{\times}\;20\;size$ matrix was used in a linear multiple regression and the scanner's color representation of scanner was better than a digital still camera's color representation. When using the sRGB color space, the original copy and the output copy had a color difference of 11. Therefore it was more efficient to use the linear multiple regression method than using the sRGB color space. After the input device underwent a color transformation, the additivity of the LCD monitor's R, G and B signal value improved and therefore the error in the linear formula transformation decreased. From this change, the LCD monitor with the GOG model applied to the color transformation became better than LCD monitors with other models applied to the color transformation. Also, the color difference varied more than 11 from the original target in CRT and LCD monitors when a sRGB color transformation was done in restricted conditions.

  • Objectives : This study aims to summarize Tang Zong-hai's Qi transformation theory of the Six meridians through his book "Shanghanlun Qianzhubuzheng傷寒論淺注補正" where he integrated Western anatomy with the Qi transformation theory of East Asian Medicine to interpret Zhang Zhong Jing's "Shanghanlun(傷寒論)". The objective is to assist clinical application. Methods : Focusing on the contents of disease of the six meridians in the "傷寒論淺注補正", Tang's theories on the function of Zangfu(臟腑), Opening-Closing-Pivot(關闔樞), Inter-communication of Zangfu(臟腑相通), the Twelve Meridians(十二經脈) from his other publication "中西匯通醫經精義" were examined and related to in the process of explaining Qi transformation theory in detail. Results : 1. The Qi transformation function of the Taiyang meridian is related to "膀胱者, 氣化則能出" where the Small Intestine and Bladder inter-communicate. 2. The Qi transformation function of the Yangming meridian is related to the control of dryness and dampness through the Qi transformation of "陽明不從標本, 從乎中." 3. The Qi transformation function of the Shaoyang meridian is related to the Life-Fire function of the Triple Energizer-Gallbladder-Pericardium coalition through "少陽屬腎." 4. The Qi transformation function of the Taiyang meridian refers to the Heart Fire nurturing the Spleen Earth by creating 膏油 through veins. 5. The Qi transformation function of the Shaoyin meridian is related to the controlling of the Nutrient Qi(營氣) and Defense Qi(衛氣) through '心主血脈, 腎主元氣.' 6. The Qi transformation function of the Jueyin meridian is related to the ability of 和風 which results from '陰盡陽生' to harmonize and control the balance of Water Coldness(水冷) and Fire Heat(火熱). Conclusions : Tang's Qi Transformation Theory of the Six Meridians is his key theory explained from the perspective of Qi transformation of disease in the six meridians of "Shanghanlun", closely related to basic theories such as theory of Zang form(臟象學說), Opening-Closing-Pivot(關闔樞), Inter-communication of Zangfu(臟腑相通), the Twelve Meridians(十二經脈) of East Asian Medicine.

  • Fashion have been expressed by a face through various a period, social change, and various culture changing. Human expresses as "Transformation" by applying these needs of changing to the fashion. A origin tribe expressed its own self by using direct body transformation and extreme decorations in the past. However, human express creative and esthetic desire based on shape, material, and transformation method in the present time characteristics of the body. Exceptional transformation breaking a existing fixed idea appeared frequently due to dissolution through transformation which is positive expression method in the fashion from 20th century. As a results, followings are obtained in this study. First, human body transforms by using a tool or intermediation in investigation of aesthetic meaning for human body. The object, Transformation, is stably transformed by disintegration, distortion, exaggeration and simplification reduction, as design's sensitivity. Second, transformation from relation of clothing composition is expressed by extension, reduction, simplification, and dissolution. In transformation from original tribe's sensitivity, past decorative desire lead to transformation of human body. To give variable change from past to present fashion, external formative will is introduced. Then, extreme expression is made by direct transformation of clothing type. It seems to be accomplished that human body's expression method is continuously changed into extension, exaggeration, reduction, and dissolution from transformation method as described before. Transformation of modem fashion is expression method by creative supervision. Extreme transformation substituted body's each part is based on immanent play and representative satisfaction. Through these transformation, it is judged that variety of creative type is achieved.

  • The baker's transformation is an ergodic transformation defined on the half open unit square. This paper considers the limiting begavior of the partial sum process of a martingale sequence constructed from the baker's transformation in the context of an invariance principle of a uniform central limit theorm.

  • Dilatometric experiment and thermodynamic calculation have been performed to determine $M_s$, $A_s$ and driving forces for ${\gamma}{\rightarrow}{\varepsilon}$ martensitic transformation of Fe-Mn alloys. The transformation temperatures($M_s$, $A_s$, $T_o) were decreased with increasing manganese content and were newly formulated as a function of manganese content. Driving force for ${\gamma}{\rightarrow}{\varepsilon}$ martensitic transformation was increased from -75J/mole to -105J/mole with increasing manganese content from 15wt.% to 25wt.%. Transformation temperature hysteresis($A_s-M_s$) was also increased from 50K to 80K with increasing mangenese content from 15wt.% to 25wt.%. The small driving force(-75J/mole~-105J/mole) and small ${\Delta}T$(50K~80K) for ${\gamma}{\rightarrow}{\varepsilon}$ martensitic transformation indicated that Fe-Mn alloys behave like thermoelastic martensitic alloys : We would like to call them semi-thermoelastic martensitic alloys.

  • Let V be a Euclidean Jordan algebra with a symmetric cone K. We show that for a Z-transformation L with the additional property L(K) ⊆ K (which we will call ’cone-preserving’), GUS ⇔ strictly copositive on K ⇔ monotone + P. Specializing the result to the Stein transformation SA(X) := X - AXAT on the space of real symmetric matrices with the property $S_A(S^n_+){\subseteq}S^n_+$, we deduce that SA GUS ⇔ I ± A positive definite.

  • The phase transformation behaviors of Ni-Ti shape memory alloys were investigated through a DSC(Differential Scanning Calorimetry). The annealing temperatures were applied from $600^{\circ}C,\;700^{\circ}C,\;800^{\circ}C,\;and\;900^{\circ}C$ for their effects on the phase transformation behaviors. Based on the results of DSC, phase transformation behaviors of shape memory alloys can be predicted by Liang's phase transformation model or Tanaka's phase transformation model.

  • Alois Riegl's aesthetic theory of visual perception provided one of important conceptual backgrounds for Vienna Art Nouveau architecture. Riegls theory of visual perception consists of geometric style and two-dimensional transformation. Riegl's theory of geometric style is based on the modern aesthetic theory of abstraction, which says that the artistic perfection can be obtained not from a direct imitation of natural objects, but from an abstract transformation of them. Riegl's theory of two-dimensional transformation, on the other hand, aims at obtaining artistic perfection by disintegrating volumetric conditions of natural things into planes and combining the planes thus obtained into another new world of art. These two theories of Alois Rigl's provided an important aesthetical background for the design strategy of 'abstract ornamentaion of two-dimension' in Vienna Art Nouveau architecture. This paper is to review the basic concept of Alois Rigl's theory of geometric style and two-dimensional transformation.
