1. Objectives This Study is to find efficacy of Red Poria and White Poria used for Soyangin Prescriptions in Lee Je-Ma's writings. 2. Methods We analysed Soyangin Prescription with Poria in ${\ulcorner}$Dongyi Suse Bowon Chobonkwon(東醫壽世保元 草本卷)${\lrcorner}$ , ${\ulcorner}$Dongyi Suse Bowon Gabobon(東醫壽世保元 甲牛本)${\lrcorner}$ , ${\ulcorner}$Dongyi Suse Bowon Sinchukbon(東醫壽世保元 辛丑本)${\lrcorner}$ and ${\ulcorner}$Dongyi Sasang Sinpyun(東醫四象新編)${\lrcorner}$ based on the efficacy of Poria written in ${\ulcorner}$DongMugo YakSungGa(東武遺藁 藥性歌)${\lrcorner}$ . 3. Results and Conclusions 1) Red Poria and White Poria seems to be different in Sasang Constitutional Medicine. 2) Poria in Soyangin Prescription had used from the traditional medical point at the beginning, in ${\ulcorner}$Dongyi Suse Bowon Chobonkwon(東醫壽世保元草本卷)${\lrcorner}$ , but its usage was changing until ${\ulcorner}$Dongyi Suse Bowon Sinchukbon(東醫壽世保元辛丑本)${\lrcorner}$ as the point of Sasang Constitutional Medicine. 3. It is necessary to use Poria in Soyangin Prescription as the essence of Soyangin's life because it effects on the whole body without any distinction from body's upper part with lower part and body's exterior part with interior part.

Purpose: The purpose of this study was to evaluate the repeatability of dental white light scanner. Methods: The impression(Zerosil, Dreve, Germany) were digitized in white light scanner(Identica, Medit, Korea) to create 3-dimensional surface-models. The distribution of the discrepancies between the number of points in the corresponding CRM models and the point clouds in the others were measured by a matching-software(PowerInspect 2012, Delcam Plc, UK). The discriptive statistics were used for statistical analysis(SPSS 20.0). Results: The measurement of repeatablity showed very good reliability. The mean(SD) discrepancy value on the white light scanner digital models was 8.7(0.67) ${\mu}m$, based on SD and absolute mean values. Conclusion: These in vitro studies showed that repeatability of dental white light scanner is high reliability. These results can be confirmed in further clinical studies.

Binary systems of a white dwarf showing mass transfer activities are classified into cataclysmic variables and symbiotic stars. In the case of cataclysmic variables, the companion is usually a late type main sequence star filling its Roche lobe, where material is transferred through the inner Lagrangian point to form an accretion disk around the white dwarf. The disk becomes unstable and highly viscous when the surface density exceeds the critical density, leading to dwarf nova outbursts. In contrast, symbiotic stars are wide binary systems having a giant as the mass donor. Some fraction of giant stellar wind is accreted to the white dwarf giving rise to various symbiotic activities. In particular, half of symbiotics show Raman O VI at 6830 and 7088, which are important spectroscopic probe of mass transfer process. Monitoring observations using 1 m class telescopes will produce valuable information regarding the mass loss and mass transfer to white dwarf stars, shedding much light on the last stage of stellar evolution of low and intermediate mass stars.

PURPOSE. This study aimed to evaluate the accuracy of digitizing dental impressions of abutment teeth using a white light scanner and to compare the findings among teeth types. MATERIALS AND METHODS. To assess precision, impressions of the canine, premolar, and molar prepared to receive all-ceramic crowns were repeatedly scanned to obtain five sets of 3-D data (STL files). Point clouds were compared and error sizes were measured (n=10 per type). Next, to evaluate trueness, impressions of teeth were rotated by $10^{\circ}-20^{\circ}$ and scanned. The obtained data were compared with the first set of data for precision assessment, and the error sizes were measured (n=5 per type). The Kruskal-Wallis test was performed to evaluate precision and trueness among three teeth types, and post-hoc comparisons were performed using the Mann-Whitney U test with Bonferroni correction (${\alpha}=.05$). RESULTS. Precision discrepancies for the canine, premolar, and molar were $3.7{\mu}m$, $3.2{\mu}m$, and $7.3{\mu}m$, respectively, indicating the poorest precision for the molar (P<.001). Trueness discrepancies for teeth types were $6.2{\mu}m$, $11.2{\mu}m$, and $21.8{\mu}m$, respectively, indicating the poorest trueness for the molar (P=.007). CONCLUSION. In respect to accuracy the molar showed the largest discrepancies compared with the canine and premolar. Digitizing of dental impressions of abutment teeth using a white light scanner was assessed to be a highly accurate method and provided discrepancy values in a clinically acceptable range. Further study is needed to improve digitizing performance of white light scanning in axial wall.

Many critics on William Faulkner's As I Lay Dying have read Addie Bundren as the disrupter of patriarchal power. By raising a question about the usefulness of language, which is the symbolic power of patriarchy and having an affair with the preacher Whitfield outside her wedlock, Addie directly challenges patriarchal power. From a quite different vantage point, however, we can read Addie as the faithful protector of the norm of whiteness in the South in light of the social hierarchy. As a former school teacher, Addie is from middle class before her marriage. By her marriage to Anse, who is a lower-class white, Addie has class anxiety that her social status in the stratum of whiteness could be degraded from a middle to a lower-class white, "white trash," which means that she is not white enough to be considered as the normative whiteness. Especially, Addie's anxiety increases due to the fact that her lazy husband is reluctant to work and relies on her neighbors, causing her family to be entrapped at the bottom in the stratum of whiteness. Therefore, she decides to take revenge on her husband after giving birth to her second child Darl by asking Anse to bury her dead body in her familial burial site in Jefferson. By rendering her family to suffer the hardship during her funeral procession, not only does she succeed in taking revenge on Anse on the surface, she regains her social status as a middle-class white by being buried in Jefferson fundamentally.

The color properties of a white or nearly colorless fabric are represented by whiteness index (WI) or yellowness index (YI). These two indexes relate to a white fabric's color quality. The purpose of this study was to identify the properties of WI and YI on the CIELAB through the simulations of estimation data for a systemization of color quality control. The results indicated that the relationship between WI and YI was a negative correlation, however the coefficients of correlation function between WI and YI were depended on hue. There were two hue transition points of the rate of changes in WI and YI. These hue transition points were the reference points to divide the hue contribution to WI and YI. These points were not the point of h=0 and h=180 and asymmetric. In addition, where the colors were same distance from the white point on the CIELAB, the rate of changes in WI and YI by ${\Delta}$Ew were depending on hue. Specifically, when WI decreased, YI of reddish and yellowish tinted colors decreased more than bluish tinted colors.

일반적으로 표준 시 환경에서의 정확한 색재현을 위해 측색적으로 우수한 성능의 디스플레이 제품들이 개발되고 있다. 그러나 디스플레이를 볼 때 실제 시 환경은 조명과 디스플레이 자체의 광에 영향을 받게 되고, 보여지는 색은 실제 의도된 색과 달리 보이게 된다. 따라서 재현된 색이 표준 시 환경 하에서의 색과 같아 보이는 대응색을 예측하는 것은 매우 중요하다. 인간 시각의 색 순응 특성을 고려하여 대응색을 재현하는 여러 가지 방법들이 제안되었다. 그러나 이 모델들은 다양한 휘도 레벨과 색도 대한 순응 화이트 점 예측에 큰 오차를 보이고 있다. 본 논문에서는 다양한 조명의 색도와 휘도 하에 변하는 시각의 순응하는 화이트 점을 예측하는 모델을 제안하였다. 제안한 모델은 조명의 휘도에 따른 두 좌표의 유클리디안 거리의 비로 모델링되며, 순응 화이트 점은 주변 휘도에 대해 S자 형태의 곡선을 따라 변화되는 특성을 갖는다. 제안한 모델은 Hunt의 휘도에 대한 순응 화이트 실험 데이터로부터 최적의 계수를 구하였고, 이는 다양한 시 환경에서 대응색을 찾는 색 순응 모델에 적용될 수 있다. 제안된 눈의 순응 화이트 모델은 디스플레이 장치의 기준 백색을 결정하는 이론적인 기준으로 사용될 수 있다.
