Statistical Entropy of a Higher-Dimensional Black Hole

ZhaoRen,GuoYong,DingBingJun 한국물리학회 2003 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.43 No.6

By using the method of quantum statistics, we directly derive the partition function of the bosonic and the fermionic elds in a d-dimensional Schwarzschild-Ads black hole and obtain a integral expression for the black hole's entropy. Then, via the improved brick-wall method, membrane model, we obtain the statistical entropy of the black hole and nd that we can choose a proper parameter in order to let the thickness of the lm tend to zero and have it approach the surface of the horizon. Consequently, the entropy of the black hole is proportional to the area of the horizon. In our result, we also take the spinning degeneracy of various particles into consideration. The stripped term and the approximation taken in the original brick-wall method no longer exist. In the whole process, the physics is clear and the calculation is simple. We oer a new simple and direct way of calculating the entropy of higher-dimensional black holes.

关于契丹大、小字的区别

ZhaoHashengaowa 한국몽골학회 2019 몽골학 Vol.0 No.56

The Khitan people have once used two scripts named Khitan large script and Khitan small scripts. The former was created in 920, while the latter was created a bit later than that. Although the two scripts record the same language, they differ in such aspects as glyphs, fonts, and nature. The present paper first introduces the creation time and application scope of Khitan large and small script. Then it describes the characteristics of some inscriptions in Khitan large and small script. In addition, it presents the characteristics of Khitan large and small scripts. The former is with more glyphs and complex font, while the latter is with fewer glyphs and simple font. Finally, the different views of scholars on the nature of Khitan large and small script are listed, and the ideographical feature of Khitan large script and phonetic feature of Khitan small script are expounded through examples. 契丹大、小字是契丹族所使用过的文字。契丹大字创制于920年,契丹小字的创制年代略晚于大字。契丹大、小字虽然均记录了契丹语,但在字母、字形、性质等方面具有不同之处。本文首先介绍了契丹大、小字的创制时间和使用范围。其次叙述了契丹大、小字文献资料的特征,其中主要介绍了较有特色的碑刻文献。另外介绍了契丹大、小字的特征,即大字的字母多,字形繁琐,小字的原字少,字形简单。最后,列举了学者们对契丹大、小字性质问题的不同观点,并通过实例阐述了契丹大、小字表意文字和表音文字的特征。

Statistical inference of some effect sizes

ZHAOJUN,심성철,김형문 한국통계학회 2020 Journal of the Korean Statistical Society Vol.49 No.3

The reporting of effect sizes in social-scientific articles is becoming increasingly widespread and encouraged, particularly when research and experimental designs are involved. Two widely used experimental designs where the uniqueness of estimation can be guaranteed, the cell means and treatment effect models, are first introduced. Then, under those two experimental designs, it is proposed to explore the distributions of the effect sizes such as eta-squared ( 2 ), omega-squared ( 2 ) and Cohen’s f 2 . For each effect size in every experimental design, it is found that the distribution or transformation of distribution belongs to the non-central Beta family. Confidence intervals for effect size in the corresponding hypothesis are obtained by applying the results from the distributions combined with the probability limits. Based on the first two moments of distributions, which lead to the mean and standard deviation, a simulation study is given to help better understand the behaviour of 2 at different sample sizes and group numbers. This provides a reference for choosing sample and group sizes in experimental design. An application is reported for a psychological data set in order to illustrate how effect sizes perform in practice.

On Katherine Mansfield's Feminist Consciousness

Zhao Wenlan 청주대학교 국제협력연구원 2006 國際文化硏究 Vol.24 No.-

Katherine Mansfield contributed her short life to the short story creation and created many female images in her works. Although she is not a radical feminist theorist, her feminist consciousness makes her always concerned with women's fate and their pursuit. Combining her own life experience, she described women's sufferings in their life struggles, and portrayed women's loneliness, disillusionment and rebellion in the patriarchal society. Her stories make us feel Mansfield's concern with women problems and her exploration to women's emancipation, and also reveal her limitations in feminism.

Zhao,Yue 한국유통과학회 2019 KODISA ICBE (International Conference on Business Vol.2019 No.-

During the past twenty years, China has developed rapidly in economy. Meanwhile China s economic development has brought great many problems. Sustainable development is to achieve coordination in the ecological, economic and social aspects. Among them, the environment and resource issues are the most critical issues which affecting sustainable development in China. With China s rapid economic development, China s ecological environment is facing the most serious threat in water pollution, air pollution, solid waste pollution and the destruction of forests and biodiversity, resulting in a significant loss of the national economy. This research aims to examine whether the tragedy of the commons has hindered the sustainable development of China s economy or not. On the other hand, we try to analyze a solution to improve this situation. In the case of a clear definition of property rights, the air will have a market price. The market price will coordinate pollutant emissions. The tragedy of commons has hindered the sustainable development. The model of China’s Economic development should be changed.

휘파(徽派) 전통건축이 현대적 장신구 디자인에 미치는 영향 연구

Zhaoyibo 동방문화대학원대학교 문화예술콘텐츠연구소 2023 문화와예술연구 Vol.21 No.-

China's ancient architecture is a masterpiece in human artistic civilization, is the crystallization of the superb wisdom and exquisite skills and craftsmanship of China's ancient working people, its majestic atmosphere, unique style, exquisite and delicate details. Among the traditional ancient buildings, the gardens and water towns in China's Jiangnan area are unique, and among the green tile white-walled buildings, the Hui school architecture is the most representative, presenting the unique humanistic and artistic charm of China's Jiangnan region. In the design of modern jewelry, more and more attention is paid to the inheritance of traditional culture, the sustenance of emotional ideals and the expression of artistic ideas. The elements of the blue tile white wall building in China's Jiangnan region are integrated into the design of modern jewelry, and the fresh and elegant simplicity of the ink style building of the Hui school building shows the low-key, calm, trendy, individuality, and distinguishes the noble, gorgeous, old-fashioned, and grand of traditional jewelry, which is the fusion of two art forms, the recollection of tradition of the times, and the innovative exploration of art design. I hope to provide some inspiration and design ideas for many people who study and explore the jewelry design industry. 중국의 고건축물(古建築物)은 인류문명중의 걸작으로 고대인의 출중한 지혜와 정밀한 기예 및 장인정신의 결정체이다. 이들 건축물의 기세는 성대하며 건축양식의 풍채 또한 독특하며 정교하고 섬세하였다. 특히 중국 강남 지역의 고건축물은 원림(園林), 수곽(水廓, 水鄕) 등과 청와(靑瓦)와 백벽(白壁)으로 이루어진 독특한 풍경을 지니고 있다. 또한 그 청와와 백벽으로 이루어진 고건축물 중에서도 강남지역의 독특한 예술매력을 보여주는 휘파(徽派) 건축이 가장 대표적이다. 오늘날 현대 장신구 디자인에서는 전통문화에 대한 전수와 계승, 그리고 정감 및 예술에 대한 사상의 구현을 더욱 중요시하고 있다. 이에 본고에서는 강남지역의 청와와 백벽 건축물의 요소를 현대 장신구의 디자인에 유입함을 연구하였다. 휘파(徽派)건축의 수묵(水墨)양식 건축은 청신하고 아담하며 고풍스러운 느낌이다. 이는 현대 장신구의 수수하고 진중하며 개성적인 모습으로 전개되어 전통적인 장신구와의 귀족적적이며 화려하고 고루함 등과 상대적으로 차별이 되었다. 이들 휘파(徽派) 건축물과 현대 디자인은 예술형식의 융합이며 전통에 대한 추억이다. 그러므로 본고는 현대 예술 디자인의 창조적인 탐색이다. 이를 바탕으로 장신구 디자인을 탐구하는 동학들에게 새로운 디자인의 창의와 폭넓은 사고에 도움이 되길 바란다.

The Influence of Content Marketing on E-commerce Platforms: Evidence from China

Zhao,Yuzhu,Kim,Daeki,Gwon,Hyejeong 한국상품학회 2020 商品學硏究 Vol.38 No.5

The e-commerce industry has advanced into the “Red Ocean” earlier than anticipated. If e-commerce platforms continue to expand with the traditional business model in which product operation is at the center, it may be challenging for platforms to enhance their competitiveness and maintain their customers. Hence, many platforms are attempting to innovate their business models. The integration of content marketing with e-commerce activities has emerged as a popular tool to attract customers by creating compelling content and offering to sell appropriate services or products online. This study combines key points of traditional e-commerce with market changes. The influence of traditional factors (logistics service quality and product diversity) and content marketing factors (content quality and social presence) on E-commerce platforms is examined. We select customer experience as the mediator between traditional and content marketing factors and customers’ repurchase intention. A total of 307 valid questionnaires were collected from Chinese users. By using AMOS 24.0, data analysis is carried out, the importance of content marketing in the online market is identified and recommendations are put forward for the development of such platforms.

兪吉濬 《西遊見聞》의 언어자본 고찰 ― 序⋅備考⋅年譜를 분석대상으로

zhaotailian,정진강 중국어문논역학회 2020 中國語文論譯叢刊 Vol.0 No.46

The style of Seo-Yu-Gyun-Moon(西遊見聞) is regarded as an indispensable text for understanding the development of language history and early modern context of the Korean enlightenment, and it is the catalyst for using Korean and Chinese characters in combination. This paper analyzes the morphological characteristics of Korean-Chinese combination in Seo-Yu-Gyun-Moon(西遊見聞) and examines the linguistic capital of Yu Gil-Jun, who he has studied in Japen an the United States. Using Bourdieu’s habitus, field of language and Cultural Capital as the main researching methods to analyze the linguistic capital in <Chronology of Yu Gil-Jun's Life>⋅<Preamble>⋅<Appendix> written by Yu Gil-Jun. As a result, according to Bourdieu’s habitus discourse formula, Chinese played the dominant role as Yu Gil-Jun’s first habitys. In the acquisition of second habitus, the effects of the first habitus showed the mode of code swiching and these are Yu Gil-Jun’s systematical Chinese habitus. Futhermore, through the vocabulary of Seo-Yu-Gyun-Moon(西遊見聞), the embodied Chinese character habitus was presented as objective data.
