Traditional wedding dresses have had a high market demand in China in recent years. Traditional wedding dresses from the Tang dynasty occupy an important position among traditional Chinese dresses, and they are also favored by young women. This study was conducted to develop the rushan and qun patterns of traditional wedding dress styles from the Tang dynasty for women in their twenties in China. For this purpose, the rushan and qun patterns of Tang and Song dynasty dresses and modern traditional dresses were collected and analyzed. Additionally, the developed patterns were validated for suitability through appearance evaluations of virtual and real fittings. The following proportions of the developed patterns were proposed: H/3.3 for rushan length, H/33 for collar width, H/1.08 for total sleeve length, H/6 for sleeve width, H/8.5 for sleeve hem width, and H/1.55 for qun length. In addition, the developed patterns received high scores in the appearance evaluations of the virtual and real fittings. Therefore, the developed rushan and qun patterns are expected to have high utility in the current traditional wedding dress industry.

The arrival of the Internet of Things and 5G technology enables users to rely on edge computing platforms to process massive data. Data sharing based on edge computing refines the efficiency of data collection and analysis, saves the communication cost of data transmission back and forth, but also causes the privacy leakage of a lot of user data. Based on attribute-based encryption and blockchain technology, we design a fine-grained access control scheme for data in edge computing, which has the characteristics of verifiability, support for outsourcing decryption and user attribute revocation. User attributes are authorized by multi-attribute authorization, and the calculation of outsourcing decryption in attribute encryption is completed by edge server, which reduces the computing cost of end users. Meanwhile, We implemented the user's attribute revocation process through the dual encryption process of attribute authority and blockchain. Compared with other schemes, our scheme can manage users' attributes more flexibly. Blockchain technology also ensures the verifiability in the process of outsourcing decryption, which reduces the space occupied by ciphertext compared with other schemes. Meanwhile, the user attribute revocation scheme realizes the dynamic management of user attribute and protects the privacy of user attribute.

This study examined how Chipogwan[緇布冠] with such a long history has been changed in China and Korea. With regard to the name, material, use and form of Chipogwan, the results of this study is summarized as follows. Chipogwan was mentioned continuously in ancient books of ceremonies and literature from the Tang dynasty [唐代], but from the Song dynasty [宋代] new name Chigwan [緇冠: a black hat] appeared besides Chipogwan. The two names were transmitted to Joseon dynasty [朝鮮] and used together until the mid Joseon dynasty, but from the 18th-19th centuries, Chipogwan was adopted according to ancient ceremonies and this name has been used continuously until today. The change of the name reflects the change of the material. Ancient Chipogwan was made of hemp [布] but when the term Chigwan appeared in the Song dynasty it was made of paper and Sa [紗: a 2-end simple gauze]. As other materials were added to hemp, po (布) was omitted from Chipogwan. As to the use of Chipogwan, it was a coronet used in purification ceremonies [齋冠] in ancient times. Then, it was used as Chogagwan [初加冠: a first hat putting on] in coming-of-age ceremonies [冠禮] from Zhou dynasty (周). During the Song and Joseon dynasty, Chipogwan was used in coming-of-age ceremonies as well as in daily life. As to the form, Chipogwan in ancient books of rites and the Song dynasty was a small coronet covering the topknot. In the Joseon dynasty, the form of Song dynasty was followed until the mid period, and then after the mid $18^{th}$ century, another form was proposed according ancient books of rites and an independent form of ceremonial coronet appeared that covered the entire head rather than covering only the topknot.

This study examined the effects of nicotinamide on proliferation, differentiation, and energy metabolism in a primary culture of bovine adipocytes. After treatment of cells with 100-500 $\mu{M}$ nicotinamide, cell growth was measured using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), and cellular lipid content was assessed by Oil Red O staining and a triglyceride (TG) assay. Several factors related to energy metabolism, namely adenosine triphosphatase (ATPase) activity, nitric oxide (NO) content, nitric oxide synthase (NOS) activity, the number of mitochondria and the relative expression of glyceraldehydes-3-phosphate dehydrogenase (GAPDH), peroxisome proliferator-activated receptor-$\gamma$ ($PPAR_{\gamma}$) and inducible NOS (iNOS), were also investigated. Results showed that nicotinamide induced both proliferation and differentiation in bovine preadipocytes. Nicotinamide decreased NO production by inhibiting NOS activity and iNOS mRNA expression, and controlled lipolytic activity by increasing ATPase activity and the number of mitochondria. The present study provides further evidence of the effects of nicotinamide on lipid and energy metabolism, and suggests that nicotinamide may play an important role in the development of bovine adipose tissue in vivo. This emphasizes the importance of investigating bovine adipose tissue to improve our understanding of dairy cow physiology.

In this study, YakMyeongSi were considered to define relations of Tradional Korean Medicine(TKM) and literature. In the introduction, present related studies were searched to clarify YakMyeongSi are completely different from medical property songs(YakSeongGa). Related data about YakMyeongSi and YakSeongGa were extracted for the initial findings. In chapter 2, medical name verse was defined as 'a type of free verses with one or more medical names in each verse to be interpreted ordinarily' based on records and examples of YakMyeongSi. In China, it originated from "Book of Odes" and "Songs of Chu", and it was most popular in the Song-China. Medical names actually referred to medical names in the early forms of the Warring States Period, but the complete form of YakMyeongSi started to appear in the Tang-China. In chapter 3, 34 YakMyeongSi and 5 related data were suggested in tables as the present conditions of Korean YakMyeongSi. With actual examples, better comprehension of YakMyeongSi were intended. Also, the fact that Korean YakMyeongSi were completed in forms at the end of Goryeo and beginning of Joseon dynasty. The motivations of writing YakMyeongSi were also studied. Medical names were put into verses because they well expressed landscapes and emotions. Propagation of medical knowledge was the basis of YakMyeongSi. There are limits in defining the relations of TKM and literature with some YakMyeongSi. More studies must be carried out on YakMyeongSi in various records with details and interests. Also, study to define general relations of TKM and literature must be carried out together by examining TKM in literary forms such as medical introductions or medical property songs and literature pieces that expressed principles and materials of TKM.

In China, the phenomenon called 'Korean Wave' has boosted the interest in Korean pop culture, such as TV drama, music and films, and even in the general culture and society. As Korean singers, movie actors and talents become popular beyond acceptance of public culture, those who learn Korean, buy Korean products and visit Korea have emerged. Especially, most Chinese women have used Korean hair cosmetics and the interests in Korean hair cosmetics are increasing, since cosmetic companies entered China early due to Korean wave. Thus, the status of purchase of Korean hair cosmetics is growing day by day in China. In particular, since the environment is established to buy hair cosmetics easily in Myeong-dong which is one of the shopping tourism special districts, many Chinese tourists are crowded there. Based on such phenomenon, this study explored the differences in perceptions towards 'Korean Wave' among Chinese tourists who purchased Korean hair cosmetics in Myeong-dong, and analyzed the factors that largely determine the interest in Korean hair cosmetics and their purchase behavior. Therefore, this study is aimed at contributing to the development of hair cosmetics products and the market amid Korean Wave. As the research methods, 100 answered questionnaires were collected with target of Chinese tourists at 20s and 40s who purchased Korean hair cosmetics in Myeong-dong once 120 questionnaires were distributed. In-depth analysis was conducted and final research data were used. It was confirmed that Korean fever positively affected the Chinese tourists' purchase behavior and satisfaction of hair cosmetics, and the interests in Korean hair cosmetics at 20s were higher than at 40s. People at 20s had higher awareness, satisfaction and intention of repurchase of hair cosmetics compared rather than people at 40s. The research confirmed that Chinese tourists are very interested in Korean hair cosmetics as the pop music craze has led to the general Korean Wave, and differences in such perceptions have led to significant differences in the product purchase behavior.

The smart substation is the heart of a transmission system, which is particularly emphasized as the most significant composition of smart grids in China. In order to assess the functionality performance of substation technologies, this paper presents methods used to identify the most promising solutions for smart substation design and to evaluate the technical levels of available technologies. The multi-index optimization model is presented to address the issue of smart substation planning. A mathematical model of the planning decision problem is established with multiple objectives consisting of economic, reliability, and green key indices, and many kinds of concerns including physical and environmentally friendly operations are formulated as a set of constraints. With respect to the assessment of the technical level regarding integration of advanced technologies into a substation, a modified grey whitenization weight function is adopted to structure a novel grey clustering method. The proposed grey clustering approach is used to overcome the difficulty of insufficient quantitative assessment capacity for traditional methods. The evaluation of technical effects provides the classification definition for the development phase and the maturity level of the smart substation. The effectiveness of the proposed approaches in planning decision-making and evaluation of construction efforts is demonstrated with case studies involving the actual smart substation projects of Wenchongkou substation in China Southern Power Grid (CSG) and Mengzi substation in State Grid Corporation of China (SGCC).
