As Europe is a weaker actor mainly due to her digital underdevelopment, the EU is settling on the regulatory side of digital sovereignty. The article is to comparatively analyze the European and Chinese AI ethical guidelines considering the strategic and normative scope of the guidelines as well as their implications on the legal frameworks of AI both in Europe and China. In this field, the most important initiative in the EU was carried on by the High-Level Expert Group on Artificial Intelligence, which, in 2019, released the “Ethics Guidelines for Trustworthy AI,” a catalogue of principles as well as operative measures to achieve Trustworthy AI. In China, instead, the most important initiative was the “Beijing AI Principles” released in 2019 by the Beijing Academy of Artificial Intelligence, and the “Principles to Develop Responsible AI for the New Generation Artificial Intelligence: Developing Responsible Artificial Intelligence” released in 2019 by the New Generation AI Governance Expert Committee.

The EU, China, and other WTO members recently released their concluded MPIA with its Annexes I and II as a temporary arrangement to deal with the appeals of panel rulings before the Appellate Body resumes its operation. The WTO dispute settlement mechanism is a complete unit with unique features and inherent logic. Although this arrangement maintains the two-tier process with arbitration to replace the appellate review, there is a fundamental difference between them, which is embodied not only in the dispute settlement process but also in the implementation of the rulings. The challenges that the WTO dispute settlement mechanism encounters are not limited to those procedural issues, but they are also connected with the substantive rules, with which the procedural issues should be jointly resolved. This is the correct way to deal with the current challenges and to reform the multilateral trade regime.

Well-crystallized vanadium pentoxide V2O5 thin films are fabricated on MgO single crystal substrates by using pulsed-laser deposition technique. The linear optical transmission spectra are measured and found to be in a wavelength range from 300 to 800 nm; the data are used to determine the linear refractive index of the V2O5 films. The value of linear refractive index decreases with increasing wavelength, and the relationship can be well explained by Wemple’s theory. The third-order nonlinear optical properties of the films are determined by a single beam z-scan method at a wavelength of 532 nm. The results show that the prepared V2O5 films exhibit a fast third-order nonlinear optical response with nonlinear absorption coefficient and nonlinear refractive index of 2.13 × 10−10 m/W and 2.07 × 10−15 cm2/kW, respectively. The real and imaginary parts of the nonlinear susceptibility are determined to be 3.03 × 10−11 esu and 1.12 × 10−11 esu, respectively. The enhancement of the nonlinear optical properties is discussed.

Bi2MoO6 (BMO) via the structure-directing role of CO(NH2)2 is successfully prepared via a facile solvothermal route. The structure, morphology, and photocatalytic performance of the nanoflake BMO are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), fluorescence spectrum analysis (PL), UV-vis spectroscopy (UVvis) and electrochemical test. SEM images show that the size of nanoflake BMO is about 50 ~ 200 nm. PL and electrochemical analysis show that the nanoflake BMO has a lower recombination rate of photogenerated carriers than particle BMO. The photocatalytic degradation of tetracycline hydrochloride (TC) by nanoflake BMO under visible light is investigated. The results show that the nanoflake BMO-3 has the highest degradation efficiency under visible light, and the degradation efficiency reached 75 % within 120 min, attributed to the unique hierarchical structure, efficient carrier separation and sufficient free radicals to generate active center synergies. The photocatalytic reaction mechanism of TC degradation on the nanoflake BMO is proposed.

복장은 한 사람의 성격을 반영하고 개인의 심미적 수준 및 내재적 수양을 직관적으로 체현한다. 한 민족에게 이는 민족의 문화와 풍속 더 나아가 한 민족의 사상과 심미를 체현한다. 이는 일종 특수한 언어이고 매 역사 시기의 경제적 발전, 생활 환경, 종교적 신앙을 체현하기도 한다. 우리나라의 각 민족의 복장 특징에는 각 민족의 문화 형태가 들어있다. 중국 복장은 5,000년의 발전 역사를 지니고 있고 그 중 만족 복장 중의 치파오는 중국 복장 발전 역사 중 독특한 매력을 지니고 있을 뿐더러 그 속에 숨겨진 의미도 있다. 치파오의 정신에는 민족의 지혜가 숨겨져 있다. 민족의 신앙은 치파오가 수수께끼가 가득한 매력을 지니게 하였다. 어떠한 사회 혹은 민족이든 시시각각 변화하고 있는데 이는 문화 자체 혹은 기타 문화와 서로 접촉하여 생긴 문화적 융합과 변화이다. 치파오는 샤먼 복장 문화의 영향을 받아 한족 문화를 경험하고 또 치파오의 시대까지 오게 되었다. 복장 제도의 제한이든 민족 문화의 영향이든 치파오의 색채와 도안은 사람들이 아름다운 생활 형태에 대한 동경을 표현하였다. 치파오는 중국 전통적인 복장 문화의 중요한 조성 부분으로서 치파오 중의 요소는 역사적 문명을 계승하였을 뿐만 아니라 자신의 민족 특색 또한 보류하였고 참고, 전통, 재창조를 통하여 더욱 잘 융합시켰다. 치파오의 발전과 변화는 민족 복장 사이의 상호 반응에 유력한 작용을 하였다. 치파오의 요소는 이미 세계 복장 문화 속에서 풍부한 시대와 문화적 특징을 체현하였고 현대 복장 디자이너들에게 수많은 영감과 창작 원천을 제공하였다. 이후 치파오는 중국에서만 입는 것이 아니라 세계 적으로도 사랑을 받게 되었으며 현대에 수많은 예복의 양식 또 한 중국 치파오의 스타일 및 꽃무늬 도안을 참고한 것이다. 이러한 전통적인 복장은 현대 디자이너의 눈에는 기타 용도가 있을 것이고 그들의 창작 중 전통적인 ‘중국식 요소’는 새로운 빛을 발하게 될 것이다 — 이는 중국 전통적인 민족 복장이 세상에 가져다 준 서프라이즈와 마찬가지이다.

Unboxing videos allow consumers a vicarious experience of a product, with more emotional connection than a review. Unboxing is conceptualised as a practice distinct from opening a box, imbued with meaning for the viewer and consumer giving it potential as a marketing tool in attracting consumers’ attention.

The development of Information Communication Technologies (ICTs) has dramatically changed the way of hotel booking. The increasing number of online consumers provides abundant data for demand forcasting in revenue management. The current methods e.g. historical data analysis, normally focus on studying consumers’ behaviors and preferences in the hotel but may not be able to integrate that out of the hotel such as dining, travelling, shopping and entertaining, which will bring crucial references to the co-relationship between these consumption and the way of hotel booking. This research adopts a persona approach to infer consumers’ preference probability by using a variety of real-time data. Quantitative methods are employed. In order to predict the booking needs accurately, this research establish a Bayesian network on the online platform for life service that can be associated with various consumer behavior data. The results indicate that in the environment of uncertain demand, the algorithm is effective and applicable, which will help directors of hotel revenue management in accurate price planning and decision making.

Counterfeit luxury is big business in China (Chen et al. 2018). The U.S. Chamber of Commerce estimates China to be the source of 86% of the world’s counterfeit luxury goods worth about $397bn (USCC 2016). Counterfeit luxury encompasses not only low quality replicas (Lai and Zaichkowsky 1999), but also high quality products that are appear almost identical to original brands. However, the price of high quality counterfeits amounts in many cases to only 10% of that of the originals (Geiger-Oneto et al. 2013). This makes high quality counterfeit luxury brands a major threat to established luxury brands. Luxury brand marketers, therefore, require a better understanding of what motivates target consumers to purchase either original or counterfeit luxury brands.

The purpose of this paper is to investigate factors driving parasocial relationships and their effect on brand equity. A conceptual model including the following variables is proposed: opinion leader attributes, parasocial relationship, brand equity and the moderating effect of endorser-brand congruency. The proposed research model is analyzed using a survey of 301 Chinese consumers. Structural equation modelling is employed to examine the hypothesized relationships among all variables. The findings show that the opinion leader attributes of expertise and exploration positively affect the parasocial relationship between consumers and the endorser, and the parasocial relationship and brand equity are positively associated. Furthermore, endorser-brand congruency acts as a moderator on the relationship between opinion leader attributes and the parasocial relationship. The implications, limitations, and discussions are provided.

Orthorhombic DyMnO3 films are fabricated epitaxially on Nb-1.0 wt%-doped SrTiO3 single crystal substrates using pulsed laser deposition technique. The structure of the deposited DyMnO3 films is studied by X-ray diffraction, and the epitaxial relationship between the film and the substrate is determined. The electrical transport properties reveal the diodelike rectifying behaviors in the all-perovskite oxide junctions over a wide temperature range (100 ~ 340 K). The forward current is exponentially related to the forward bias voltage, and the extracted ideality factors show distinct transport mechanisms in high and low positive regions. The leakage current increases with increasing reverse bias voltage, and the breakdown voltage decreases with decrease temperature, a consequence of tunneling effects because the leakage current at low temperature is larger than that at high temperature. The determined built-in potentials are 0.37 V in the low bias region, and 0.11 V in the high bias region, respectively. The results show the importance of temperature and applied bias in determining the electrical transport characteristics of all-perovskite oxide heterostructures.

중국 소비자들의 소비영향력이 커지고 있음에도 불구하고 라이프스타일과 명품소비에 관한 연구는 매우 부족 한 실정이다. 본 논문은 중국의 소비 주체인 여성 소비자 중에서 특히 명품소비의 새로운 계층으로 등장한 20대 젊은 여성 소비자 321명에 대해 설문조사를 실시하였으며 그들의 라이프스타일을 분석하고 명품소비행동을 연구하였다. 연구 결과에 따르면 20대 중국 여성 소비자들의 라이프스타일(의생활, 식생활, 주생활, 소비생활, 여가생활, 가치관)을 분류한 결과 전통적 보수형, 계획적 성공추구형, 비계획적 소비추구형 3가지 라이프스타일로 분류되었다. 전통적 보수형은 소득수준이 낮고 모든 요인들에 있어서 보수적이고 소극적 태도를 보였며, 계획적 성공추구형은 여성의 사회진출 증가로 인해 사회적 성공을 추구하면서 계획적으로 생활하는 집단이며, 비계획적 소비추구형은 쇼핑을 즐기며 지출을 많이 하는 특성을 보여주었다. 구입한 명품 브랜드의 종류, 연간 명품 구매 수량, 연간 명품 구매 금액 및 명품 구매 이유는 통계적으로 유의한 차이가 있었으나 명품 품목, 명품 구매 장소와 정보원은 유의한 차이가 없었다. 최근 중고명품 시장이 크게 증가하고 있어 새 명품과 중고 명품에 대한 태도와 행동을 비 교한 결과 새 명품의 구매의도와 추천의도가 중고 명품에 비해 더 높은 것으로 나타났다. 본 논문은 중국 소비자들에 대한 체계적 연구의 틀과 방법 및 유용한 자료를 제공함으로써 중국 소비자 행동 연구와 라이프스타일 연구, 명품 소비 연구의 학문적 발전에 기여할 수 있는 것으로 기대된다. 또한 명품 브랜 드들이 20대 중국 여성들을 위한 마케팅 전략을 수립하는 데 있어 실무적인 시사점도 제공할 수 있는 것으로 기대된다.
