Purpose - This study examines the effects of purchasing factors of consumers based on customer satisfaction and repurchasing intention buying through Internet shopping malls. The subject of this study are Chinese residents who have lived over a year in Korea. Research design, data, and methodology - In this study, former research related with internet shopping malls' customer satisfaction and repurchase intention was revised. Based on past research, the internet shopping mall purchasing factors divided to 4 factors; factors of product, price, service, and promotion. 5 hypotheses were made. They are

Product factors of internet shopping malls have meaningful effect to customer satisfaction,

Price factors of internet shopping malls have meaningful effect to customer satisfaction,

Service factors of internet shopping malls have meaningful effect to customer satisfaction,

Promotion factors of internet shopping malls have meaningful effect to customer satisfaction,

Customer satisfaction factors of internet shopping malls have meaningful effect to customer repurchase intention. Measurements developed 4~5 items to each factor and questionnaires were made. The survey was conducted on 1,000 Chinese people. Out of 292 surveys, 9 were excluded which responded nothing or were unfilled. Finally 283 surveys were used in empirical analysis with SPSS 22.0 statistical program. Hypotheses were verified by structural equation modeling. Results - The following conclusions are shown in the empirical study. First, the service and promotion factors of internet shopping mall have effects on customer satisfaction. Second, customer (Chinese people who live in Korea) satisfaction have effects on repurchase intention. Third, the products value and price level of internet shopping mall have strong effects on repurchasing intention. Conclusions - There are suggestions that Chinese customers satisfied with Korean internet shopping malls might increase their royalty to the shopping malls as possibility of repurchase arises. This study has differentiating points with preceding researches that subjected residents in Korea. But there are limitations that this study also used purchasing factors used in preceding studies. Also this study has limitations, such as generalization in global market circumstances because this study subjected only Chinese people and not global customers. Therefore, further study executed complementary with those limitations would be an interesting study.

With the development of the Internet, e-commerce is rapidly developing, and e-commerce through the Internet has become a major distribution channel for selling products and services to consumers and buyers. However, as Internet shopping develops, consumer dissatisfaction and conflict are increasing. In this regard, this study examined how consumer dissatisfaction caused by using an Internet shopping mall, which is currently taking the core position in commerce activities, leads to consumer complaints, and how these complaints affect the necessity and intention to use the arbitration system. As a result of the study, the following implications were obtained. First, it will be necessary to remove the root cause of consumer complaints by continuously monitoring consumer complaints, rather than staying at passive consumer complaints such as defective product exchange and damage compensation for dissatisfaction with Internet shopping malls. Second, it can be said that the function of the arbitration system is required to protect the rights and interests of consumers using the Internet shopping mall and to actively improve the problems in the event of a damage situation or a problem situation. Lastly, academia's continuous research will be needed, and governments and related organizations will need to continuously provide and promote information to users of Internet shopping malls.

Deploying advanced home networking technologies and modern home-networked devices in residential environments provides a playground for new home applications and services. Because home multimedia entertainment is among the most essential home applications, this paper presents an appealing home media content sharing scenario: home-networked devices can discover neighboring devices and share local media content, as well as enormous amounts of Internet media content in a convenient and networked manner. This ideal scenario differs from traditional usages that merely offer local media content and require tedious manual operations of connection setup and file transfer among various devices. To achieve this goal, this study proposes a proxy gateway architecture for home multimedia content distribution. The proposed architecture integrates several functional mechanisms, including UPnP-based device discovery, home gateway, Internet media provision, and in-home media content delivery. This design addresses several inherent limitations of device heterogeneity and network interoperability on home and public networks, and allows diverse home-networked devices to play media content in an identical and networked manner. Prototypical implementation of the proposed proxy gateway architecture develops a proof-of-concept software, integrating a BitTorrent peer-to-peer client, a UPnP protocol stack, and a UPnP AV media server, as well as media distribution and management components on the OSGi home gateway platform. Practical demonstration shows the proposed design and scenario realization, offering users an unlimited volume of media content for home multimedia entertainment.

This study developed the traceability information for tracing fishery products from the production step to the consumption step in the distribution channel of fishery products. Based on it, we further presented the theoretical linkage between traceability information and perceived qualities of internet shopping malls, and then investigated how traceability information affected trust and perceived usefulness in the internet shopping mall to find the key success factors of internet shopping malls of fishery products. We collected 194 responses from internet consumers who had prior experience on purchasing fishery products. This survey data was used to empirically test the ten research model hypotheses by using PLS. The PLS results indicated that traceability information had significant impact on trust and perceived usefulness. Finally, trust, perceived usefulness and perceived ease of use were found to be related to online consumers' intention to purchase fishery products.

This paper surveys consumer policies for the internet transaction in the developed countries. Recently the internet transaction has been witnessing a remarkable change represented by the rapid spread of "revolution of distribution". It cannot be, however, stated that internet transaction will dominates all the market places without enhancing consumer's reliability in the internet transaction. Many countries made an efforts to the consumer protection in order to develop infra-structure of information industry. We will soon discover a new paradigm that consumer protection is not a tool for development of cyber market but the goal itself. We survey the process of consumer policies discussed in the developed countries and study the point of prevailing arguments of the consumer protection in the internet transaction. The arguments discussed in OECD meetings are debatable, especially, to the degree of government intervention in the field of consumer protection between EU and US. In contrast of US insisted on the minimum intervention of the government, EU suggest the opinion of more aggressive role of government in consumer policy in the cyber market. This paper attempts to provide several guide lines of Korean consumer policy in the cyber market.
