Recent increase of commercial network Integration to World Wide Web(WWW) shifts an ordinary commerce to electronic environment. This draws more people to examine re-assurance of their secure transaction. This study investigates current status of security methodology for Electronic Payment System and extracts important axis of security level for electronic payment. Using these axis as security evaluation criteria, the research proposes a security matrix which consists of four different level of security granularity, hence allowing evaluation of a nation-wide credit card based payment system. Feasible usage of this matrix contributes to security analysis of the electronic system as whole, hence providing better secured electronic environment.

Enterprise portal(EP) is the emerging service and technologies in recent business area. We divided the three subportal of EP - IPP(Information Processing Porta), DPP(Decisino Processing Portal) and EKP(Enterprise Knowledge Portal). IPP include the information processing area that conduct the general business field. DPP is the area that can support the employee's decision processing and making according to their roles. The function of EKP assist the tacit knowledge management and the collaboration job among knowledge workers. If we efficiently integrate and aggregate their subportal, our business information system can achieve more efficient and effective business performance. Also we can anticipate this model that serve the system environment, supporting the user friendly circumstance, enforcing e-business activity, connecting between customer and supplier, positioning more competitive advantage.

Nowadays, omnichannel is a new kind of e-commerce channel. Many retailers invest in this channel to maximize customers' benefits as well as increase competitive advantage and business performance. To operate this channel effectively, the role of IT competence is very important. With the flexibility and integration of IT competence in omnichannel, retailers can optimize service quality and bring customer benefits that are outstanding in comparison with the traditional channel. Because of this significance, this research was carried out to evaluate the effects of IT competence on the business performance of retailers in Vietnam's omnichannel environment through the mediating role of customer value creation and competitive advantage. A quantitative research method is used through a survey with 200 managers working in retail companies operating omnichannel in Vietnam. After collecting data, PLS-SEM software is used to analyze the relationship among these above factors in omnichannel. The results prove that there are positive effects of IT competence on other elements in the research model. All direct and indirect effects are valuable when bootstrapping. Based on the results, some managerial implications are given to managers of retail companies using omnichannel to improve customer values and increase competitive advantage and business performance in the Vietnam context.

Database schema integration is a significant issue in information systems. Because schema integration is a time-consuming and labor-intensive task, many studies have attempted to automate it. Researchers typically use XML as the source schema and leave much of the work to be done through DBA intervention, e.g., there are various naming conflicts related to relationship names in schema integration. In the past, the DBA had to intervene to resolve the naming-conflict name. In this paper, we introduce an algorithm that automatically generates relationship names to resolve relationship name conflicts that occur during schema integration. This algorithm is based on an Internet collocation and English sentence example dictionary. The relationship between the two entities is generated by analyzing examples extracted based on dictionary data through natural language processing. By building a semi-automated schema integration system and testing this algorithm, we found that it showed about 90% accuracy. Using this algorithm, we can resolve the problems related to naming conflicts that occur at schema integration automatically without DBA intervention.

In this paper, a conceptual framework describing the dynamics of click and mortar businesses is provided. It directs our attention to the many potential sources of synergy that are available to firms that choose to integrate e-commerce with their existing traditional forms of business. It further emphasizes the many actions that firms can take to minimize channel conflicts and help achieve the benefits of synergy. Finally, it describes four categories of synergy-related benefits from the integration of e-commerce with traditional businesses, including potential cost saving, gains due to enhanced differentiation, improved trust, and potential extensions into new markets. The utility of the framework was demonstrated using the case of an electronics retailer that has chosen to tightly integrate its large chain of retail stores with its Web-based electronic store. The framework was also used to develop a series of propositions that can guide future empirical research. The discussion points to the need to develop new types of metrics to better judge the contributions of e-commerce channels, and provides some guidance for future empirical research that can test whether, and under what conditions, integrated click and mortar business models work well. Thus, the purpose of this study is to present the combining physical and virtual presence in e-commerce.

The e-commerce market faces significant credit risks due to the complexity of the industry and information asymmetries. Therefore, credit risk has started to stymie the growth of e-commerce. However, there is no reliable system for evaluating the creditworthiness of e-commerce companies. Therefore, this paper constructs a credit risk evaluation index system that comprehensively considers the online and offline behavior of online retail enterprises, including 15 indicators that reflect online credit risk and 15 indicators that reflect offline credit risk. This paper establishes an integration method based on a fuzzy integral support vector machine, which takes the factor analysis results of the credit risk evaluation index system of online retail enterprises as the input and the credit risk evaluation results of online retail enterprises as the output. The classification results of each sub-classifier and the importance of each sub-classifier decision to the final decision have been taken into account in this method. Select the sample data of 1500 online retail loan customers from a bank to test the model. The empirical results demonstrate that the proposed method outperforms a single SVM and traditional SVMs aggregation technique via majority voting in terms of classification accuracy, which provides a basis for banks to establish a reliable evaluation system.

In the process of global transportation, many value chains which have different business process, system and technology level respectively are connected to each other. To obtain end-to-end visibility of transportation, these kind of discrepancy has to be solved appropriately. In this paper, the realization of global visibility is discussed in three point of view such as 'Data Sourcing', 'System integration' and 'System Operation'. First, the data sources of global visibility are described especially from the point of enterprise applications view, and then system integration is presented using various current e-commerce technologies for example XML, EDI and so on. Finally, flexible operation of visibility function is suggested which satisfies different goals of each value chain.
