This study examines the costume artifacts discovered in the burial site of Choi Kyung Sun(1561~1622), which was moved from Gangwon in Gangrung Province. About 30 artifacts, including costumes, were recovered from Choi Kyung Sun's grave. The collection of men's coats discovered in the grave consisted of a Dallyeong (Official's robe), Jing-nyeong(Man's coat), Jungchimak(Man's coat), Cheolrik(Man's coat), Chang-ui(Man's coat), Gwang-su-ju-ui(Man's coat), and Do-po(Man's coat). Han-sam(Undershirts), Jeo-go-ri(Jacket), and trousers were also recovered, along with several items made of textiles, such as the cloth used to shroud and wrap the body. The costume artifacts recovered from Choi Kyung Sun's grave have several characteristics that distinguish them from other early 17th-century costume artifacts. Firstly, the body had a hairband made from horsehair. Secondly, the men's trousers were of the type worn before the Japanese Invasion(1592~1597). Thirdly, the style of the coats' sleeves, when compared with artifacts from other regions, was from an earlier era. Through these costume artifacts, it can be inferred that people who lived in the Gangwon Province, which was far away from Seoul, continuously wore outfits from before the Japanese Invasion, and trends spread slowly.
Objective: For the standardization and quality control of eleutheroside E in Eleutherococcus species, HPLC analysis was performed and eleutherosdie E content was compared in 23 kinds of Eleutherococcus species collected from Korea and China. Methods: The content of eleutheroside E in stem bark of Eleutherococcus species collected from Korea and China were analyzed by HPLC. 0.5% phosphoric acid and acetonitrile was used as mobile solvent. Validation of HPLC analysis method was confirmed by analyzing specificity, linearity, precision and accuracy following ICH guideline. Results: Content of eleutheroside E was determined to be 1.0-1.6% and 0.5-0.8% in Korean and Chinese E. senticosus, respectively. Content of eleutheroside E in E. sessiliflorus was 0.7-1.1% and 0.2-0.4% respectively in Korean and Chinese origin. All calibration curves showed good linear regression. The method showed good precision and accuracy with intra-day and inter-day variations of 0.880-3.442% (RSD) and 0.606-3.328% (RSD), respectively, and average recovery was of 0.141-1.363% (RSD), for the eleutheroside E analyzed. Conclusion: These results might be used to establish a criterion of eleutheroside E in Eleutherococcus species.
지금까지 제안되어 있는 다항 로짓 회귀모형의 적합도 검정 방법들에 대하여 저자들이 제안한 방법들이 타당한지를 확인하고자 본 연구를 진행하였다. 여러 검정 통계량들 중 그룹화 전략을 이용한 통계량들 (Fagerland 등, 2008; Bull, 1994; Pigeon과 Heyse, 1999)을 선정하였고, 이러한 통계량의 기반이 되는 피어슨 χ<sup>2</sup> 통계량 또한 같이 비교하였다. 제안된 분포가 모의실험의 상황 하에 얻어지는 귀무분포와 유사한지, 그리고 부적절한 모형의 판별을 적절히 수행하는지에 대하여 확인하였으며, 실제 자료에 세 가지 방법을 적용한 결과를 비교, 평가하였다. Several goodness-of-fit test statistics have been proposed for a multinomial logit regression model; however, the properties of the proposed tests were not adequately studied. This paper evaluates three different goodness-of-fit tests using grouping strategies, proposed by Fagerland et al. (2008), Bull (1994), and Pigeon and Heyse (1999). In addition, Pearson (1900)`s method is also examined as a reference. Simulation studies were conducted to evaluate the four methods in terms of null distribution and power. A real data example is presented to illustrate the methods.
