Central bank digital currency (CBDC) is generally defined as the digital form of a country’s fiat currency. Based on the distributed ledger technology and other financial technology, CBDC could improve the efficiency of domestic and cross-border payments, increase payment safety and soundness, and promote financial inclusion. However, it is argued that the introduction of CBDC would threaten data security and invade personal privacy. Currently, this issue has received growing concern, and some recommendations are proposed by countries or international organizations, like privacy design, restrictions on public authorities and payment intermediaries, and establishing independent supervisory authority. Other suggestions include getting countries involved in international coordination and promoting the formation of unified standards. Among major economies, China is the first to launch CBDC, which is known as e-CNY. Based on an overview of the privacy protection legislation in China, this article attempts to describe the rules that should be followed when dealing with personal data generated in e-CNY circulation.

Amorphous molybdenum sulfide ( MoSx) has been regarded as a promising hydrogen evolution reaction (HER) catalyst due to its mild preparation conditions and low-cost precursor materials. In this work, we report a simple strategy combining the growth of amorphous MoSx on the surface of metal organic frameworks (ZIF-67) and annealing treatment to prepare Co-doped MoSx nanopolyhedrons (denoted as CoMoSx NPs). The CoMoSx NPs exhibit excellent HER activity in acid condition with an overpotential of 188 mV at a current density of 10 mA cm− 2 (η10), and a relatively stable overpotential after 2000 cyclic voltammetry (CV) cycles testing. The excellent HER performance of the CoMoSx NPs can be attributed to the doping of Co element adjust the electronic structure and increase the conductivity of catalyst, and the nanopolyhedrons structure which can expose more active sites for HER electrocatalytic. This study offers a low-cost and simple strategy to prepare high-activity HER catalyst, which holds great promises in developing advanced electrocatalysts for energy storage.

This research proposes the application of new technologies in tourism advertising to resonate with and respond to unconscious desires that are embodied within consumers. The ethnographic research first questions how consumers form their desires regarding tourism and illustrates that advertising does not create desire; consumer desires for travel, often embodied, exist before consumers are exposed to advertising messages. Such desires derive from past experiences, imagination and sensorial imageries learned from stimuli. Consumers react positively to multi-sensorial, empathetic messages. AI technologies, such as the convolutional neural network algorithm, can be used to apply traditional cultural symbols in art design (Lin 2021). Virtual mirror-based learning technology mirrors back to individuals their social network, identifying their most important contacts, influencers, and communication bottlenecks. The research aims to connect existing and future new technologies that provide the “posthuman mystic,” to offer consumers to experience a new level of their own being, giving room for different kinds of human relations--friendship, connection, and novelty --through one’s avatars (Bolger 2021) and to construct a “decentered, highly relational mode of reality giving agency to everyone, not only to all other humans, but to natural and technological subjects as well” (Delio 2020, p. 115). Such virtual world, with an example like the Metaverse, is “a combination of contextualization and wholemaking from the standpoint of posthumanism and mysticism” (Bolger 2021, p.768). The research then deciphers consumers’ positive reactions to websites that resonate with imagination sensorial desires, past experiences, desired activities and “LIVE” desires. Based on the findings, the research summarizes cross-disciplinary research of tourism advertising and new technologies 4.0 and conceptually illustrates how the applications of new technologies 4.0 may assist with the understanding of consumers’ multi-sensorial desires, imagination, and memories to design empathetic advertising messages. As such, advertisers may be in systematic dialogues with consumers and create multi-sensorial messages that resonate consumer desires.

This study aims to integrate the protection motivation theory (PMT) model and attitude to explore the factors influencing consumers’ usage behavior toward online food delivery platform services (OFDPSs) during the COVID-19 pandemic. The utilitarian value and hedonic value of OFDPSs, which may influence consumers’ attitude, were also included in the integrated research model. This study collected a total of 384 participants who are with experience in using OFDPSs during the COVID-19 pandemic in Taiwan for analysis

Many companies seek to position their brands as global players to benefit from favorable quality and prestige inferences. Yet, recent research calls into question whether global brand positioning strategies are invariably beneficial. In many Western markets, the political environment becomes increasingly tense, with nationalism and ethnocentrism on the rise. Against this background, we seek to answer the question: How does political ideology influence the effectiveness of global brand positioning strategies? Do global brand positioning strategies create more value in liberal or conservative environments?

Previous studies offered inconsistent empirical results for the influence of customer participation on service satisfaction. One possible explanation for this inconsistency is that existing conceptualizations of customer participation do not clearly differentiate the distinct roles of customer participation in service. To address this gap, Dong and Sivakumar (2015) have proposed an updated classification for customer participation based on “output specificity,” which refers to the degree to that the nature of the output is influenced by the person who provides the resource. The output of the customer participation can either be “specific” or “generic”. The “specific output” is defined as the expected service outcome can be idiosyncratic depending on whether the service is provided by the customer or the employee. In contrast, “generic output” refers to expected service outcome is well defined regardless of whether it is delivered by the service provider or the customer. How output specificity of customer participation influences service satisfaction still lacks of empirical examination.

Given the conundrum of moral washing in CSR communication, this research examines the effectiveness of narrative richness using storytelling in marketing. In the process, the moderating role of moral imagination is further explored. An online experiment with a 2 (Narrative Richness: High vs. Low) x 2 (Moral Imagination: High vs. Low) between-subjects factorial design was conducted with two well-known companies (Shell vs. Facebook) suffered from a reputation crisis as the target brands. The results (N = 287) showed that the effects of narrative richness on consumer responses, including positive emotion, negative emotion, and behavioral intention, were significant for Facebook whereas its effect on positive emotion was significant for Shell. Most importantly, the two-way interaction between narrative richness and moral imagination on attitude toward the brand was significant for Shell, indicating that the effect of narrative richness on attitude toward the brand was augmented by moral imagination. In other words, consumers with high moral imagination view narrative-rich messages with virtuous thoughts to figure out the conundrum of CSR communication for the company, and vice versa. Theoretical and managerial implications are discussed.

In recent years E-commerce platforms recommend some products for consumers based on their shopping history and user persona. However, sometimes, unfamiliar products or styles would be recommended to consumers unintentionally or intentionally. Curiosity drives consumers to try but this idea would be declined with the consideration of product fit uncertainty. Augmented Reality (AR) is the integration of digital information with the user‘s environment in real-time (Hilken et al. 2018), it can deal with issues related to physical apprehension that hinder consumers’ online shopping (i.e, clothes, cosmetics), especially for the unfamiliar style. This study aims to investigate whether AR technology could improve consumers' purchase likelihood. Augmented Reality (AR) can enhance customer experiences in a multichannel environment (Hilken et al. 2017). AR Integrates online experiences into the offline experience (Hilken et al. 2018), such as virtual try-on or magic mirrors. Customers often find it difficult to imagine how firms’ products and services fit them personally or fit with their environment (Hilken et al. 2018). Drawn on AR, consumers can easily evaluate the fitness between themselves and the selected products. Prior studies have explored the different underlying processes of why AR technology could improve consumer purchase intention and customer experience. For instance, according to the situated cognition theory, AR creates a feeling of spatial presence (Hilken et al. 2017). The usage of AR benefits mental imagery, improving decision comfort (Heller et al. 2019). AR can compensate for consumers’ need for touch and offer hedonic and/or utilitarian benefits (Gatter et al. 2022). Based on media richness theory, AR offers more information for customers (Hoffmann et al. 2022), which represents a fitting concept for customers to evaluate the product (Javornik 2016).

Social media began to boom in the 2000s. According to statistics, there are 92.3% of internet users are social media users who spend nearly two and a half hours daily on social media. Instagram is considered the most popular image-sharing platform, with more than 1.2 billion monthly active users. Meanwhile, consumers nowadays refer to and follow online reviews to assist their decision-making process more efficiently.

With the development of social media, most people will use social media to watch the videos of digital influencers to get spiritual comfort, and they will think that digital influencers are like friends who are connected with their own lives. However, most of the previous studies focused on the influence of digital influencers on followers’ behavioral intentions (e.g. loyalty, and purchase intention). They rarely discussed the online social well-being obtained by followers after watching digital influencers' posts. Therefore, this study integrates the attributes of followers (loneliness, low self-esteem, empathy) and the characteristics of digital influencers (social attractiveness, expertise, homophily) to explore the influence of the parasocial interaction established between digital influencers and followers on followers’ online social well-being. This study uses the Internet to collect questionnaires and takes users who have watched digital influencers' posts on social media as the research object. A total of 597 valid questionnaires are collected. The research results show that: the characteristics of digital influencers (social attractiveness, expertise, and homophily), and followers' attributes (low self-esteem and empathy) have positively affected parasocial interaction. It is noteworthy that loneliness has no significant effect on parasocial interaction.

Biomass carbon materials with high rate capacity have great potential to boost supercapacitors with cost effective, fast charging– discharging performance and high safety requirements, yet currently suffers from a lack of targeted preparation methods. Here we propose a facile FeCl3 assisted hydrothermal carbonization strategy to prepare ultra-high rate biomass carbon from apple residues (ARs). In the preparation process, ARs were first hydrothermally carbonized into a porous precursor which embedded by Fe species, and then synchronously graphitized and activated to form biocarbon with a large special surface area (2159.3 m2 g− 1) and high degree of graphitization. The material exhibited a considerable specific capacitance of 297.5 F g− 1 at 0.5 A g− 1 and outstanding capacitance retention of 85.7% at 10 A g− 1 in 6 M KOH, and moreover, achieved an energy density of 16.2 Wh kg− 1 with the power density of 350.3 W kg− 1. After 8000 cycles, an initial capacitance of 95.2% was maintained. Our findings provide a new idea for boosting the rate capacity of carbon-based electrode materials.

To solve the problem of water pollution, researchers have proposed a photocatalytic degradation technology, in which the key factor is the development of efficient photocatalytic materials. Graphitic carbon nitride (g-C3N4), an n-type semiconductor, has been widely studied due to its suitable band gap (2.7 eV), low cost, easy preparation, non-toxicity, and high photostability. However, the pure-phase g-C3N4 still has defects such as low specific surface area, insufficient visible light absorption, low charge mobility, few active sites for interfacial reaction, and easy recombination of photogenerated electron–hole pairs, which leads to the lower photocatalytic activity of g-C3N4. Aiming at the problems mentioned above, this paper focus on the synthesis of g-C3N4-based composites with high photocatalytic activity via lemon juice induction method. Thiourea and lemon juice were selected as precursors, and carbon quantum dots (CQDs) as electron mediators were introduced anchoring on the surface of g-C3N4 to build g-C3N4/CQDs with compact interface. The results showed that small-sized CQDs are uniformly distributed on the surface of g-C3N4, and the g-C3N4/CQDs composite has a 2D0D structure, which reduces the recombination of photogenerated electron–hole pairs. The photocatalytic degradation efficiency of 4% g-C3N4/CQDs for RhB reaches the highest data of 90.9%, and the photocatalytic degradation rate is 0.016 min− 1, which is about 2.3 times that of g-C3N4. After four cycles of photocatalytic reaction, the photocatalytic degradation efficiency of the material remained at 81.7%. Therefore, the g-C3N4/CQDs synthesized via lemon juice induction has a more stable microstructure, and the charge separation efficiency is greatly improved, which is suitable for practical photocatalytic environmental protection.

본 논문에서는　칼 융의 분석심리학의 만다라 개념과 종교에 서의 만다라의 개념을 비교 정리하고 양자의 내재적 가치와 치 유적 메카니즘을 탐구하였다. 만다라는 원래 종교적 개념으로서, 인도 라마교, 불교 밀종의 중요한 관상 법문이었다. 시대와 종교의 발전에 따라 만다라 역시 다양한 형태의 변천을 거치며 현대에는 주로 두루마리 그 림과 같은 불화로 널리 알려져 있다. 종교적 개념에서 만다라는 어떤 형태의 만다라든지 보호, 응 집, 연결, 청결한 사상성을 가지고 있다. 이러한 동양적인 불교 회화 형식은 동양문화를 중심으로 하는 철학사상을 담고 있으 며, 특히 현재 가장 널리 전해지고 있는 티베트 만다라는 그 형식적 구성에 있어 중국 본토의 도가 사상도 많이 내포하고 있다. 스위스의 심리학자 칼 융(Carl Gustav Jung)은 만다라 양식 이 서로 다른 문화적 배경에서 인류에게 공유되는 일종의 심령 적인 상징모형으로 집단 무의식의 원형임을 스스로 체험하고 임상적으로 증명했다. 그가 '만다라(mandala)'라는 용어를 택한 것은 동양의 라마교(lamaism)와 밀종 요가(tantric yoga)에서 제사권이나 마법의 형태로 명상에 도움이 되는 도구로 사용했 기 때문이다. 만다라 개념은 분석심리학에 인용돼 자성(自性)의 상징적 표 현이 됐다. 융은 만다라 양식의 문양을 끊임없이 그리면서 내 면의 혼란스럽고 무질서한 무의식이 직관적이며 의식화되는 것 을 확인하였고, 자신의 심리적인 위기를 잘 극복하고 자기통합 과 자기치유의 효과를 거둘 수 있었다. 이를 통해 융은 만다라 그림이 현대미술치료에서 적용될 수 있는 이론적 토대를 마련 했다. 본고는 불교의 밀종 만다라를 연구 대상으로 하여 동양의 만다라 기원과 전파 발전을 살펴보고, 만다라 도식 형성을 통해 동양 문화의 내면을 분석하였다. 중국 도가사상을 융합한 티베 트의 만다라는 가장 아름다운 만다라 형식으로 알려져 있으며, 융의 분석심리학에서 자성(self)의 최고 표현으로 손꼽히고 있 다. 동양의 종교 및 심리학 치료에서 만다라의 개념을 비교·분 석하여 융의 분석심리학에서의 동양의 문화에 대한 의의와 상 징성을 살펴보았다. 마지막으로 만다라의 내면화 작용을 통해 서로 다른 두 분야에서의 치유 메카니즘을 분석했다. 본 논문 은 융의 심리학의 만다라와 종교의 만다라의 개념, 이론 및 비 교 정리를 바탕으로 동양문화의 시각에서 분석심리학에 관한 개념을 깊이 이해하고 설명함으로써, 분석심리학의 발전과 응 용에 긍정적인 의의를 가져올 것으로 기대한다.

원남과 티베트는 중국 남서 국경 지역에 위치하고, 여러 민족과 종교가 혼재되어 있어 중국정부가 통치하는데 많은 어려움을 겪고 있다. 또한 국 경선의 길이가 길어 국가의 중요한 방어구역이기도 하다. 하지만 이 지역 에 대한 학계의 관심과 연구는 상대적으로 빈약하다. 이러한 상황에서 본 논문은 이 지역들의 소속민족의 발전 및 건설 그리고 이들 지역의 고토수 비(守土固边)에 대해 연구한다. 문헌연구를 통해 국가안보차원에서 소수 민족 마을에 대한 건설과 고토수비현황에 대해 기초시설, 경제발전, 민생 발전, 생태문명 등 네 가지 분야로 깊이 고찰한 다음, 이를 통해 문제점을 발견하고 해결책과 발전방안을 제시하였다.

The remarkable electrical, thermal, mechanical, and optical properties of graphene and its derivative grapheme oxide have recently gained great importance, along with the large surface area and single-atoms thickness. In this respect, several techniques of synthesis such as chemical exfoliation, mechanical exfoliation, or chemical synthesis have been discovered. However, the development of graphene with fewer defects and on a large scale poses major challenges; therefore, it is increasingly necessary to produce it in large proportions with high quality. This paper reviews the top-down synthesis approach of graphene and its well-known derivative graphene oxide. Furthermore, characterization of graphene oxide nanomaterial is a critical component of the analysis. The characterization techniques employed to determine the quality, defects intensity, number of layers, and structures for graphene oxide nanomaterial at the atomic scale. This article focuses on the different involved characterization methodology for graphene oxide with their percentage utilization for the past 11 years. Additionally, reviewing all of the characterization literature for the last 11 years would be a difficult task. Therefore, the aim is to outline the existing state of graphene oxide by different characterization techniques and provide a comparative analysis based on their percentage utilization.

The paper measures and predicts the performance of online auxiliary channel of movies released in China. Based on the signaling theory, the paper confirms that online movie consumption is generally informed by the box-office revenue of the same movie, with genres as important moderators.

In the molecular cloud G33.92+0.11A, massive stars are forming sequentially in dense cores, probably due to interaction with accreted gas. Cold dense gas, which is likely the pristine gas of the cloud, is traced by DCN line and dust continuum emission. Clear chemical differences were observed in different source locations and for different velocity components in the same line of sight. Several distinct gas components coexist in the cloud: the pristine cold gas, the accreted dense gas, and warm turbulent gas, in addition to the star-forming dense clumps. Filaments of accreted gas occur in the northern part of the A1 and A5 clumps, and the velocity gradient along these features suggests that the gas is falling toward the cloud and may have triggered the most recent star formation. The large concentration of turbulent gas in the A2 clump seems to have formed mainly through disturbances from the outside.
