A Study on Motives of Chinese Female Audiences for Watching Korean Fantasy TV Dramas

Wu, Yue,Shen, Xuezheng,Lee, Jong Yoon The Korea Contents Association 2021 International Journal of Contents Vol.17 No.2

With love as the theme and mythology, ghosts and magic as elements, Korean fantasy TV dramas have set romantic and beautiful plots and attracted a large number of Chinese female audiences. Based on Melodramatic Imagination and Stuart Hall's theory of "encoding/decoding", this paper investigated Chinese female audiences' motives of watching Korean fantasy TV dramas Hotel Druena through the form of focus group interviews to interpret reasons for the popularity of Korean fantasy TV dramas and Chinese women's overall cognition of Korean TV dramas from the perspective of female audiences. Thinking that South Korea's fantasy dramas are good at women's pursuit and desire for emotional elements, women who watch this type of south Korean TV dramas are temporarily relieving pressure of real life, thus satisfying the needs of female gaze and consumption.

Dyeing Properties, UV Protection, and Deodorization of Silk Fabric Using Hot Water Extract of Ecklonia cava

Wu Yue,이은주 한국의류학회 2022 한국의류학회지 Vol.46 No.1

To explore the potential use of Ecklonia cava as a natural dye for textiles, silk fabric was dyed with Ecklonia cava extracted by hot water under varied conditions, including temperature, duration, dye concentration, mordanting, and pH adjustment. The fabric was also evaluated for fastness, sun-protective property, and deodorization. Ecklonia cava extract was estimated by FT-IR to have polyphenol as a main functional colorant in plants, while the existence of phlorotannins through the UV-spectrum method was also confirmed. The fabric was optimized for maximum dye uptake at a temperature of 80°C for a duration of 50 minutes along all dye concentrations. The dyed fabric showed a hue of Yellow Red under all dyeing conditions while additional color tones, such as grayish and dark, were generated through mordanting and pH adjustment. Both good sun-protective properties and a positive deodorization rate were also recorded, with more than 20% (owf) Ecklonia cava extract on silk fabric. These results imply that Ecklonia cava has great potential to be used as an eco-friendly natural dye and in fashion goods with skin-health functions made of silk.

An improved resonantly driven piezoelectric gas pump

Yue Wu,Yong Liu,Jian-Fang Liu,Long Wang,Xiaoyang Jiao,Zhigang Yang 대한기계학회 2013 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.27 No.3

Piezoelectric pumps have the potential to be used in a variety of applications, such as in air circulation and compression. However, piezoelectric membrane pumps do not have enough driving capacity, and the heat induced during the direct contact between the driving part and the gas medium cannot be dissipated smoothly. When the gas is blocked, the piezoelectric vibrator generates heat quickly, which may eventually lead to damage. Resonantly driven piezoelectric stack pumps have high performance but no price advantage. In this situation, a novel, resonantly driven piezoelectric gas pump with annular bimorph as the driver is presented. In the study, the working principle of the novel pump was analyzed, the vibration mechanics model was deter-mined, and the displacement amplified theory was studied. The outcome indicates that the displacement amplification factor is related with the original displacement provided by the piezoelectric bimorph. In addition, the displacement amplification effect is related to the stiffness of the spring lamination, adjustment spring, and piezoelectric vibrator, as well as to the systematic damping factor and the driving frequency. The experimental prototypes of the proposed pump were designed, and the displacement amplification effect and gas output performance were measured. At 70 V of sinusoidal AC driving voltage, the improved pump amplified the piezoelectric vibrator displacement by 4.2 times, the maximum gas output flow rate reached 1685 ml/min, and the temperature of the bimorph remained normal after 2000 hours of operation when the gas medium was blocked.

Wu Jinyan,Wu Sai-Nan,Zhang Li-Ping,Zhao Xiansheng,Li Yue,Yang Quyang,Yuan Ruoyue,Liu Jian-Lan,Mao Hong-Ju,Zhu Ningwen 한국조직공학과 재생의학회 2022 조직공학과 재생의학 Vol.19 No.5

Senescence is an inevitable natural life process that involves structural and functional degeneration of tissues and organs. Recently, the process of skin aging has attracted much attention. Determining a means to delay or even reverse skin aging has become a research hotspot in medical cosmetology and anti-aging. Dysfunction in the epidermis and fibroblasts and changes in the composition and content of the extracellular matrix are common pathophysiological manifestations of skin aging. Reactive oxygen species and matrix metalloproteinases play essential roles in this process. Stem cells are pluripotent cells that possess self-replication abilities and can differentiate into multiple functional cells under certain conditions. These cells also possess a strong ability to facilitate tissue repair and regeneration. Stem cell transplantation has the potential for application in anti-aging therapy. Increasing studies have demonstrated that stem cells perform functions through paracrine processes, particularly those involving exosomes. Exosomes are nano-vesicular substances secreted by stem cells that participate in cell-to-cell communication by transporting their contents into target cells. In this chapter, the biological characteristics of exosomes were reviewed, including their effects on extracellular matrix formation, epidermal cell function, fibroblast function and antioxidation. Exosomes derived from stem cells may provide a new means to reverse skin aging.

Gender Trend in China’s Diplomacy and Foreign Aid: A Moral Realist Perspective

YUE;WU 계명대학교 국제학연구소 2023 국제학논총 Vol.37 No.-

China has engaged in gender issues globally, which demonstrates a gender trend in its diplomacy and foreign aid. However, little existing research has paid attention to this issue or analyzed China’s motivations. Therefore, this paper aims to examine gender trends and explore their characteristics. It also attempts to analyze China’s motivations for global engagement in gender issues and figure out the domestic challenges with the international relations theory of moral realism. It finds that China’s global engagement in gender issues is reflected in its international commitments based on international treaties, support for sustainable development goals, multilateral diplomacy, and foreign aid. However, China shows a contradictory stance on gender issues due to its small aid budget, immature institutionalization, and lack of policy planning. This paper argues that gender issues are the entry point for China to build its humane authority leadership, which is consistent with China’s diplomatic shift to major-country diplomacy of assuming more international responsibilities and engaging in global governance. Nevertheless, gender inequality, negative domestic attitudes toward feminism, and the non-intervention principle constitute internal hurdles to China’s international leadership through leading by example. Hence, it is recommended that China conduct further domestic and international reforms on gender issues to enhance its international leadership.

China’s Trilateral Development Cooperation: Contradictions and Dual Identities

( Wu Yue ),( Zhang Muhui ) 부경대학교 글로벌지역학연구소 2021 Journal of Global and Area Studies(JGA) Vol.5 No.2

Trilateral development cooperation (TrC) is an emerging modality in development assistance. China, as a donor worldwide, also engages in TrC. Existing studies have partially determined the characteristics of China’s TrC and found that China has contradictory positions on TrC. However, they do not comprehensively interpret and analyze the contradictions existing in China’s TrC and lack the support of international relations theory. With constructivism as the theoretical lens, this paper reviews the characteristics of China’s TrC, examines China’s contradicting perception and practices, and analyzes the reasons for the contradictions. It finds that China’s dual identities constitute the explanations for China’s contradictory stance on TrC. The identity of a rising power accounts for China’s positive aspect of TrC, while the identity as a developing country leads to the cautious one. In light of this, China needs to clarify which identity should be prioritized. It also needs to determine its position on neoliberalism, which is the root of the developed countries’ assistance policy, and whether to extend strategic competition with the United States to development assistance.

Optimizing opportunistic preventive maintenance strategy for multi-unit system of CNC lathe

Yue Wu,Zhaojun Yang,Jili Wang,Xiaojuan Chen,Wei Hu 대한기계학회 2022 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.36 No.1

Due to the many components in the multi-unit system (i.e., CNC machine tools), the existing preventive maintenance (PM) strategies conducting independent PM for every component are time-consuming and waste unnecessary maintenance and downtime costs. Hence, this paper introduces the idea of opportunistic maintenance into the PM and proposes an opportunistic imperfect PM approach, which is a more realistic PM policy for a multi-unit system. In this approach, the effect of PM is assumed to be imperfect to correct the failure rate of each unit. According to the corrected failure rate function, the imperfect PM strategy of a single unit is optimized by minimizing the proposed unit maintenance cost rate under the limitation of minimum reliability. Then, these independent imperfect PM strategies for units are rescheduled by the proposed opportunistic PM strategy under the condition of judging the reliability OM threshold of units. We further optimize the opportunistic PM strategy by minimizing the total maintenance cost. Finally, the advantage of our approach is verified by the case study of 18 CNC lathes.

More precise determination of V_cb & V_ub and direct CP violation in charmless B decays

Yue-liang Wu,Yu-Feng Zhou,YWhen-Yu Wang 한국물리학회 2004 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.45 No.2

More precise extractions on the two important CKM matrix elements jVcbj and jVubj are presented up to 1=m2 Q corrections, based on the complete heavy-quark eective eld theory (HQEFT) of QCD. The HQEFT as a large component QCD provides us with a complete theoretical framework for correctly and systematically evaluating the subleading and higher-order contributions in 1=mQ expansion of heavy quarks. A global analysis on charmless B decays is made, based on the isospin and SU(3) avor symmetry. An isospin relation is found to be very useful for studying SU(3) symmetry-breaking eects of strong phases and exploring new types of electroweak penguin eects. The direct CP violation in charmless B decays is predicted, and its precise measurement is helpful either for testing SU(3) symmetry breaking eects of strong phases or for probing new physics beyond standard model.

China’s Cautious Approach to the Venezuelan Crisis: Strategic Overdraft and Nonintervention Principle

YUE;WU 경희대학교(국제캠퍼스) 국제지역연구원 2021 아태연구 Vol.28 No.4

The current China–Venezuela relationship adheres to the South-South cooperation (SSC) model wherein the two countries have established an integrated cooperative approach with “loan-for-oil” deals at its core; however, in contrast with its recent softening stance on interventions, China has taken a cautious approach to the crisis in Venezuela since 2014. Nevertheless, not many studies highlight the reasons for China’s cautiousness. This paper tries to mitigate the gap by examining China’s strategic overdraft as exposed by this response and exploring the challenges in SSC model. It is herein argued that dual overdrafts of material power and credibility constitute the reason for China’s nonintervention in Venezuela. Meanwhile, as the country hoped to continue its presence in Venezuela and is concerned over the overdraft credibility risk by withdrawing, it chose adopt hedging as a form of flexible involvement. To avoid a similar situation in the future, China should neither rely on economic complementarity nor rigidly stick to nonintervention. With national economic and political interests and cooperative sustainability as a guide, China should clarify and redefine its nonintervention principle and adopt preventive measures for risk assessment and cooperation practices to innovate a more sustainable SSC model.
