A Study on the Diffusion of Mobile Payment Usage in China : Focusing on the Use Diffusion Model
Wei Wei Jiang,왕다운,최혜경 사단법인 미래융합기술연구학회 2021 아시아태평양융합연구교류논문지 Vol.7 No.9
Mobile payments have become a major payment method in China in a short period of time due to its convenience. This has gradually made the lives of Chinese consumers more mobile and improved their efficiency. In this regard, this study analyzed the current status of mobile payment usage in China based on the use diffusion model targeting 440 Chinese consumers. First, exploratory and confirmatory factor analysis was conducted to find out the influence and determinants of the spread of mobile payment use. As a result, it was classified into environmental creation, technology dependence, and technology anxiety. After that, the structural model was analyzed to verify the path hypothesis. As a result, environment creation and technical anxiety influenced the characteristics of mobile payment usage. And it was found that technology dependence, technology anxiety, and diversity among the characteristics of use had a significant effect on the diffusion outcome. In particular, technology anxiety has been shown to be an important factor that not only increases the spread and satisfaction of consumers, but also increases the intention to accept new technologies that will be introduced in the future. Therefore, research on consumer's technology anxiety is needed in the future, and this is expected to contribute to devising measures to increase consumer acceptance of technology.

Because of its greater biodiversity, ASEAN has long been a source and transit hub for transnational wildlife trafficking. Although several international and domestic wildlife enforcement mechanisms have been established, the scope and effectiveness of international legal cooperation and policy coordination between China and ASEAN remain limited. Governments have been hampered in their efforts to combat wildlife trafficking by the difficulties of investigation and prosecution in overseas jurisdictions and the maintenance of illicit supply chains by organized crime groups. This paper reviews the main trends of legal and illegal wildlife trade between China and ASEAN, explores the existing legal and policy frameworks of ASEAN countries and China, and discusses the effectiveness of cooperation between China and ASEAN countries by referring to the United Nations Convention against Transnational Organized Crime (UNTOC). Finally, put forward the legal cooperation between China and ASEAN countries in combating transnational illegal wildlife trafficking.
Protocols for Privacy-Preserving DBSCAN Clustering

Cooperative computation is one of the most important fields in computer science. In recent years, the development of networking increases the desirability of cooperative computation. But privacy concerns often prevent different parties from sharing their data. Secure multiparty computation techniques can dispel parties’ doubts about revealing privacy information in this situation. On the other hand, Data mining has been a popular research area for more than a decade. However, in many applications, the data are originally collected at different sites owned by different users. This paper considers the problem of privacy preserving DBSCAN clustering over vertically partitioned data based on some results of SMC. An efficient secure intersection protocol is first proposed. The security and complexity of the protocols are also analyzed. The results show that the protocols preserve the privacy of the data and the time complexity as well as the communication complexity is acceptable.
Impurities-contributed abnormal thermoelectric effect in a parallel double quantum dot structure
Wei-Jiang Gong,Hui-Min Wang,Yu Han,Si-Jing Zhang 한국물리학회 2014 Current Applied Physics Vol.14 No.1
We discuss the influence of local impurities on the thermoelectric effect in a parallel double quantum dot (QD) structure. It is first found that in this structure, the Fano effect contributes significantly to the enhancement of thermoelectric efficiency, especially in the case of f ¼ p. Next, impurities are introduced to couple to the QDs, respectively. We readily find that regardless of which QD is coupled to a local impurity, the thermoelectric efficiency can be enhanced by the strengthening of impurityeQD coupling. This means that the destruction of the Fano interference is not the necessary condition to suppress the thermoelectric effect. Accordingly, we hope that the numerical results can help to understand the role of impurities in adjusting the thermoelectric properties of the QD structure.

Manganese(III) 5-(4-carboxyphenyl)-10,15,20-triphenyl porphyrin chloride (Mn(TCPP)Cl) was grafted through amide bond on silica zeolite Y (HY), zeolite beta (Hβ) and hexagonal mesoporous silica (HMS). XRD, ICP-AES, N2 physisorption, SEM, TEM, FTIR and thermal analysis were employed to analyse these novel heterogeneous materials. These silica supported catalysts were shown to be used for epoxidation and good shape selectivity was observed. The effect of support structure on catalytic performance was also discussed. The catalytic activity remained when the catalysts were recycled five times. The energy changes about epoxidation of alkenes by NaIO4 and H2O2 were also computationally calculated to explain the different catalytic efficiency.
A Scheme to Improve SOS Security against DDoS Attack Using Active Network Technology
( Jiang Wei ),( Choong Seon Hong ) 한국정보처리학회 2004 한국정보처리학회 학술대회논문집 Vol.11 No.2
Secure overlay services (SOS) architecture has been proposed to provide reliable communication between clients and a target under DDoS attacks. The SOS architecture employs a set of overlay nodes arranged in three hierarchical layers that controls access to the target. Although the architecture is novel and works well under simple congestion based attacks, we observe that when the attacker uses same malicious traffic raid the SOS nodes, the SOS system can not responses this kind of repeating action, and wastes the chance to collect the information of attacker. We propose a scheme to improve the secure overlay services (SOS) against the DDoS attack.

Background: Endotoxemia is related to worse clinical outcomes in acute liver failure (ALF), but its management remains unsatisfactory. In this study, we aimed to assess whether the application of bone marrow mesenchymal stem cells (BMSCs) could eliminate endotoxemia and protect rats against ALF induced by thioacetamide (TAA). Methods: BMSCs were isolated from rats and identified by the specific morphology, differentiation potential, and surface markers. The optimal dose of TAA for this study was explored and TAA-induced ALF rats were randomized to three groups: the normal control group (Saline), ALF group (TAA + Saline), and BMSCs-treated group (TAA + BMSCs). The intestinal migration and differentiation of BMSCs was tracked in vivo, and intestinal permeability, endotoxin and inflammatory cytokines, histology, and mortality were analyzed. Moreover, we added the inhibitor of the PI3K/AKT/mTOR signaling pathway into the co-culture system of BMSCs with enterocytes and then performed CK and Villin expression experiments to assess the role of PI3K/AKT/mTOR signal pathway in the intestinal differentiation of BMSCs. Results: BMSCs migrated to the intestinal injury sites and differentiated into enterocytes, intestinal permeability was decreased compared with the ALF group. The higher expression of endotoxin and inflammatory cytokines were reversed after BMSCs transplantation in rats with ALF. Mortality and intestinal lesion were significantly decreased. Blocking the PI3K/AKT/mTOR signal pathway inhibited BMSCs’ intestinal differentiation in vitro. Conclusion: BMSCs can eliminate endotoxemia and reduce mortality in rats with ALF, and the PI3K/AKT/mTOR signal pathway is involved in intestinal differentiation. BMSCs transplantation could be a potential candidate for the treatment of endotoxemia in ALF. .
