This research investigates how users of Bilibili, a video sharing website based in China have responded to carbon neutrality. By conducting quantitative textual analyses on 3,311 comments on Bilibili using LDA topic extraction and content statistics, this research discovers that: (1) Bilibili users have assigned more weight to geopolitical topics (56.3%) than energy (22.0%) and environmental topics (21.7%). (2) When assessing carbon neutrality, Bilibili users considered geopolitical (53.8%) and energy factors (15.8%) more heavily than factors related to the class (9.2%), economy (8.9%), environment (8.7%), and definition (3.6%). (3) More Bilibili users had negative (64.6%) attitudes towards carbon neutrality, with only a small portion of them expressing positive (26.8%) and neutral (8.6%) attitudes. (4) Negative attitudes towards carbon neutrality were mainly driven by geopolitical concerns about the West's approach to China, other countries' free-riding on China's efforts and the West's manipulation of rules, doubts about the feasibility of energy transition and suspicion of capitalists exploiting consumers through this concept. This research highlights the geopolitical concerns behind the environmental attitudes of Chinese people, deepening our understanding to psychological constructs and crisis sensitivity of Chinese people towards environmental issues.

This study in concerned with the costume accessories appeared in Sam Kuk Sa ki. The accessories of both sexes were analized. Results of this research can be summarized as follows : It was appeared that names of accessories of men were fewer in number than those of women. Men\`s accessories such as a hat, bok-du, a belt,boots, shoes, and sock were mentioned in Sam Kuk Sa Ki. Women\`s accessories appeared such as a hat, a comb, a hair pin, a belt, shoes, and sock. A bok-du, boots, and a hared belt were used exclusively by men, while a hat, kwan(冠), a comb, a hair pin, a scarf, pyo( ) were worn exclusively by women. All men from different classes including true bone class as well as the common class wore bok-du, a hat, a hard belt, boots, sock ; however, class distinctions were made from materials used for those items. Also women\`s accessories were used as means of differentiating social status of the wearer by means of materials employed for each item. Especially, woman\`s hat and scarf were a symbol of the noble class. Only two classes of women from the true-bone class and women from the sixth du-pum class entited to wear hats. Wearing a scarf was not allowed to women from the common class. Class dirrernetiations were made by the materials used for hats and scarves. Materials for a scarf such as gold and silver leaf, pecock tail, and king fisher fly feather were restricted to women from true-bone class. Such as man\`s hat bok-du( 頭), use of women\`s comb and hair pin, scarf, leggings were items drived from Tang China. It clearly showed that costume accessories of Silla were heavily influenced by the Chinese. At the same time the costume accessories were sued to make sex difference among the people of Silla. Woman wore a soft belt made of cloth while man wore a hard belt. Woman\`s hat, a scarf, a comb, a hair pin, a belt or sash for a shirt, and leggings were woman\`s sex symbol. Thus, costume accessories of Silla appeared in Sam Kum Sa Ki functioned as means of differentiating social status of the wearer such as sex,class and rank in the society. Also, they showed that Silla kingdom had close cultural relationship with Tang China.

Objective: Inbreeding depression of reproduction is a major concern in the conservation of native chicken genetic resources. Here, based on the successful development of strongly inbred (Sinb) and weakly inbred (Winb) Langshan chickens, we aimed to evaluate inbreeding effects on reproductive traits and identify candidate genes involved in inbreeding depression of reproduction in Langshan chickens. Methods: A two-sample t-test was performed to estimate the differences in phenotypic values of reproductive traits between Sinb and Winb chicken groups. Three healthy chickens with reproductive trait values around the group mean values were selected from each of the groups. Differences in ovarian and hypothalamus transcriptomes between the two groups of chickens were analyzed by RNA sequencing (RNA-Seq). Results: The Sinb chicken group showed an obvious inbreeding depression in reproduction, especially for traits of age at the first egg and egg number at 300 days (p<0.01). Furthermore, 68 and 618 differentially expressed genes (DEGs) were obtained in the hypothalamus and ovary between the two chicken groups, respectively. In the hypothalamus, DEGs were mainly enriched in the pathways related to vitamin metabolism, signal transduction and development of the reproductive system, such as the riboflavin metabolism, Wnt signaling pathway, extracellular matrix-receptor interaction and focal adhesion pathways, including stimulated by retinoic acid 6, serpin family F member 1, secreted frizzled related protein 2, Wnt family member 6, and frizzled class receptor 4 genes. In the ovary, DEGs were significantly enriched in pathways associated with basic metabolism, including amino acid metabolism, oxidative phosphorylation, and glycosaminoglycan degradation. A series of key DEGs involved in folate biosynthesis (gamma-glutamyl hydrolase, guanosine triphosphate cyclohydrolase 1), oocyte meiosis and ovarian function (cytoplasmic polyadenylation element binding protein 1, structural maintenance of chromosomes 1B, and speedy/RINGO cell cycle regulator family member A), spermatogenesis and male fertility (prostaglandin D2 synthase 21 kDa), Mov10 RISC complex RNA helicase like 1, and deuterosome assembly protein 1) were identified, and these may play important roles in inbreeding depression in reproduction. Conclusion: The results improve our understanding of the regulatory mechanisms underlying inbreeding depression in chicken reproduction and provide a theoretical basis for the conservation of species resources.

This paper aims to analyze the characteristics of the contemporary Chinese fashion market and the competitiveness of Korean fashion brands in China. Fashion professionals experienced in both the Korean and Chinese fashion markets participated to investigate the Shanghai market and consumers. The results of in-depth interviews show that Shanghai is the most favorable city among Tier 1 cities for Korean fashion brands planning on entering into the Chinese market. Shanghai consumers are open to international brands and highly prefer newness in fashion. Contemporary menswear was selected as a potentially big market due to the increase of unique, young, upper-middle-class male consumers. The Korean fashion brands' strength is that they are capable of satisfying Shanghai consumers with excellent product planning and sensory design capabilities. Their disadvantage is that their brand recognition is weaker than that of global and international brands, and their ability to localize to the Chinese market is weak. The opportunity comes is from the Korean Wave, which is a positive for Korea's products and has good geographical access. The threat is that the Shanghai market is fiercely competitive; having access to many worldwide brands, and the competitiveness of Chinese brands is on the rise. To enter the Shanghai market, creative design ability, trendy product development, skill, and appropriate PR methods such as using Korean culture contents would be required to satisfy the young, powerful consumers in Shanghai.

The Republican Period of China (1912 to 1949) was when the archetypes of thought (constituting contemporary China) engaged in heated rivalry and were directly influenced by Korea through frequent exchanges. This study analyzes the characteristic of Chinese women's aesthetics towards the human body with a focus on visual materials (such as articles and illustrations concerning hairstyle, makeup, skincare, fashion, and gymnastics) featured in the Chinese women magazines of Fun$\ddot{u}$zazhi (婦女雜誌) and Linglong (玲瓏). This study analyzes these magazines and compares them with Korean counterparts. The movement of the developed and controlled human body was a common characteristic of this period; however, compared to the Chinese, the Japanese colonial period of Korea resulted in an introspective self-examination through excessively objectified eyes. Dress and adornment as the symbol of a new civilization acted as the most remarkable signifier. The overlapping of a western image with a Japanese image led to more resistance in Korea. The criterion for the value of a women's external appearance (that traditionally dualized womanly virtues) collapsed and dress was accepted as an expression of individuality instead of as a social class. The human body was traditionally recognized as a microcosm of the universe that dominated the natural principle of Yin-Yang and the Five Elements. However, the ideal human body was postulated and the aesthetic consciousness of the body changed into an imaginary view of the human body that proceeded to keep the body fit for and gave birth to the concept of supplementing the deficiency of the beauty of the human body with dress and makeup.

Due to the lack of an accretion disk in a polar (magnetic cataclysmic variable, MCV), the material transferred from the secondary is directly accreted onto the white dwarf, forming an accretion stream and a hot spot on the white-dwarf component. During the eclipses, different light components can be isolated. Therefore, the monitoring of eclipsing polars could provide valuable information on several modern astrophysical problems, e.g., CVs as planetary hosting stars, mass transfer and mass accretion in CVs, and the magnetic activity of the most rapidly rotating cool dwarfs. In the past five years, we have monitored about 10 eclipsing polars (e.g., DP Leo and HU Aqr) using several 2-m class telescopes and about 100 eclipse profiles were obtained. In this paper, we will introduce the progress of our research group at YNOs. The first direct evidence of variable mass transfer in a CV is obtained and we show that it is the dark-spot activity that causes the mass transfer in CVs. Magnetic activity cycles of the cool secondary were detected and we show that the variable mass transfer is not caused by magnetic activity cycles. These results will shed light on the structure and evolution of close binary stars (e.g., CVs and Algols).

The purposes of this study were to examine the characteristics of elements composing the cultural identity of Chinese architectural and spatial design, and to analyze the expression characteristics and influencing factors of contemporary restaurant design. With these purposes, first, this study reviewed related literature in order to find the characteristics of tangible elements observed in intangible elements and space expression characteristics forming the cultural identity of China. Second, this study conducted a case study in order to understand the expression characteristics of the design of Chinese restaurants in Shanghai and to find factors influencing the design. In order to sample the subjects of the case study, the researcher selected 18 restaurants that were recommended repeatedly in books on Chinese restaurants and tourism and major Internet sites or highly evaluated by visitors, and then choose 15 of them that were found to be fit for the purpose of the survey. According to the result of the survey, the restaurants were largely grouped by type into 10 cases of fine dining, 3 of middle-class casual dining, 1 of fast food, and 1 of luxury tea house serving traditional tea and snacks. Of these restaurants, 46.7% (7 cases) were of CM-CM-CM type, namely, using contemporary simple elements in all of external spaces, indoor spaces, and decorations, 20% (3 cases) were of CM-CM-CT type, using contemporary and simple external and indoor spaces, and traditional furniture or articles, 20% (3 cases) were of CT-CM-CT type, using traditional external spaces such as traditional buildings, contemporary simple finishing of indoor spaces, and traditional articles such as palace lanterns and traditional doors and windows, and 13.3% (2 cases) were of CT-CT-CT type, using traditional elements in their original forms in general. Through this research and survey, cultural identity showing Chinese traditions observed in the expression characteristics of restaurant spatial designs was confirmed, and it was also found that the identity was underlain by ideologies, values, lifestyles, etc. that had long accumulated through the long history of the country and exerted a great influence.

A new classification method and recognition algorithms for printed Korean and Chinese character is studied for Korean text which contains both Korean and Chinese characters. The proposed method utilizes structural features of the vertical and horizontal vowel in Korean character. Korean characters are classified into 6 groups. Vowel and consonant are separated by means of different vowel extraction methods applied to each group. Time consuming thinning process is excluded. A modified crossing distance feature is measured to recognize extracted consonant. For Chinese character, an average of stroke crossing number is calculated on every characters, which allows the characters to be classified into several groups. A recognition process is then followed in terms of the stroke crossing number and the black dot rate of character. Classification between Korean and Chinese character was at the rate of 90.5%, and classification rate of Ming-style 2512 Korean characters was 90.0%. The recognition algorithm was applied on 1278 characters. The recognition rate was 92.2%. The densest class after classification of 4585 Chinese characters was found to contain only 124 characters, only 1/40 of total numbers. The recognition rate was 89.2%.

To recognize F5-like (such as F5 and nsF5) steganographic algorithm from multi-class stego images, a recognition algorithm based on the identifiable statistical feature (IDSF) of F5-like steganography is proposed in this paper. First, this paper analyzes the special modification ways of F5-like steganography to image data, as well as the special changes of statistical properties of image data caused by the modifications. And then, by constructing appropriate feature extraction sources, the IDSF of F5-like steganography distinguished from others is extracted. Lastly, based on the extracted IDSFs and combined with the training of SVM (Support Vector Machine) classifier, a recognition algorithm is presented to recognize F5-like stego images from images set consisting of a large number of multi-class stego images. A series of experimental results based on the detection of five types of typical JPEG steganography (namely F5, nsF5, JSteg, Steghide and Outguess) indicate that, the proposed algorithm can distinguish F5-like stego images reliably from multi-class stego images generated by the steganography mentioned above. Furthermore, even if the types of some detected stego images are unknown, the proposed algorithm can still recognize F5-like stego images correctly with high accuracy.
