This study would inquire into the fashion image and design characteristics of Peng Liyuan, the first lady of China that has a mighty influence on the recent global economy and consumption. For this purpose, first, this study investigated the fashion image of Peng Liyuan according to the role which she performs as a first lady and analyzed how the fashion image appears and changes by year and role type. Second, this study analyzed the design characteristics of Peng Liyuan's fashion image, focusing on the silhouette, fashion items, coordinated items, colors, and textile patterns. The scope of the research was limited to the dresses worn by Peng Liyuan from March 14, 2013 to September 30, 2015. The fashion image of Peng Liyuan changed from classic and elegant image to modern image till 2015, and she reduced ethnic image and emphasized romantic image. In international diplomatic visits, she tried to express the confidence and potential of China through classic, ethnic and modern image, while in formal events of China, she showed an intention to communicate with the Chinese public with soft intimacy through elegant and ethnic images. As design characteristics in her fashion image, she flexibly changed her fashion image by the composition of silhouettes and items, which could cover her mid-life body type and made use of the form and detail of Chinese traditional qipao, appropriate coordination of scarves and brooches, the combination of chromatic color and achromatic color, appropriate uses of textile patterns and the delivery of China's image according to place and purpose. The study of Peng Liyuan's fashion image has significance to understand the fashion trend as a role model of fashion for the Chinese people and can help the domestic fashion industry that aims at the Chinese market in the future by predicting Chinese women' Fashion trend.

A novel phytase of Acidobacteria was identified from a soil metagenome, cloned, overexpressed, and purified. It has low sequence similarity (<44%) to all the known phytases. At the optimum pH (2.5), the phytase shows an activity level of 1,792 μmol/min/mg at physiological temperature (37℃) and could retain 92% residual activity after 30 min, indicating the phytase is acidophilic and acidostable. However the phytase shows poor stability at high temperatures. To improve its thermal resistance, the enzyme was redesigned using Disulfide by Design 2.0, introducing four additional disulfide bridges. The half-life time of the engineered phytase at 60℃ and 80℃, respectively, is 3.0× and 2.8× longer than the wild-type, and its activity and acidostability are not significantly affected.

A phytase gene was identified in a publicly available metagenome derived from subsurface groundwater, which was deduced to encode for a protein of the histidine acid phosphatase (HAP) family. The nucleotide sequence of the phytase gene was chemically synthesized and cloned, in order to further overexpress the phytase in Escherichia coli. Purified protein of the recombinant phytase demonstrated an activity for phytic acid of 298 ± 17 µmol P/min/mg, at the pH optimum of 2.0 with the temperature of 37℃. Interestingly, the pH optimum of this phytase is much lower in comparison with most HAP phytases known to date. It suggests that the phytase could possess improved adaptability to the low pH condition caused by the gastric acid in livestock and poultry stomachs.

The purpose of this study is to analyze types of roles and fashion of the Chinese first ladies and provide basic data for fashion image-making of first ladies. As for the research methods, the concepts, role types, and fashion of the first ladies were considered by referring to the precedent studies and relevant literature. Then, the fashion images according to role types were analyzed by collecting the photos of Chinese first ladies from the period of the Republic of China until today. The results were as follows: First, when the roles of Chinese first ladies were categorized based on ceremonial, political, and policy roles, Zhuo Lin and Wang Yeping played a ceremonial role; Wang Guangmei, Liu Yongqing, and Peng Liyuan played a political role; and Soong Qingling, Soong Mayling, and Jiang Qing played a policy role while they were first ladies. While the first ladies of the Republic of China often wore classic Chinese styles like traditional qipao as well as western clothes which contained a western influence, the first ladies of the People's Republic of China wore more colorful clothes and more accessories in the later period, and also often wore clothes that combined traditional and western elements. Second, first ladies who played a ceremonial role showed mannish and classic images; those who played a political role showed elegant, classic, and diverse images according to T.P.O; and those who played a policy role showed feminine, modern, and mannish images. Fashion images of the first ladies varied according to the level of political involvement, the sociocultural background of China at that time, and their personality and preference.

It has been reported that ubiquitin-conjugating enzyme 9 (Ubc9), the unique enzyme2 in the sumoylation pathway, is up-regulated in many cancers. However, the expression and regulation of UBC9 in glioma remains unknown. In this study, we found that Ubc9 was up-regulated in glioma tissues and cell lines compared to a normal control. UBC9 knockdown by small interfering RNA (siRNA) affected cell proliferation and apoptosis in T98G cells. Further experiments revealed that microRNA (miR)-214 directly targeted the 3' untranslated region (UTR) of UBC9 and that there was an inverse relationship between the expression levels of miR-214 and UBC9 protein in glioma tissues and cells. miR-214 overexpression suppressed the endogenous UBC9 protein and affected T98G cell proliferation. These findings suggest that miR-214 reduction facilitates UBC9 expression and is involved in the regulation of glioma cell proliferation.
