The electronic commerce of agricultural products provides benefits both to the farmers and the consumers because of direct transaction between producers and consumers. This study analyses the factors affecting consumer's purchase intention that are using electronic commerce. And the purpose of this study is to contribute to increasing the farmer's income while operating electronic commerce by applying the results of this analysis. Consumer's purchasing factors in electronic commerce were obtained through literature reviews. The research model is established with the factors and analyses through the structural equation model. The results are as following; the first is how the quality of agricultural products affects positively consumer's satisfaction and trust. When sufficient information about the seller and the products are provided in the shopping mall site there are positive effects on the consumer's satisfaction and trust. The factors of convenience like purchasing time, saving, delivery convenience affect positively consumer's satisfaction. However, the relationship with trust enhancement could not be confirmed. In addition, hypotheses of positive relationships between economic feasibility factors like low price, satisfaction and trust, were rejected. Finally, consumer's satisfaction affects trust, and both the consumer's satisfaction and trust affects positively the purchase intention. In summary, in the electronic commerce of agricultural products, consumers might use electronic commerce as they purchase the reliable high quality products directly from farmers rather than be affected by economic feasibility and convenience factors.

As the internet dramatically grows, internet electronic commerce is being increased. But, as products distributed with ESD(Electronic Software Distribution) are in the form of electronic file, it is difficult to prohibit illegal copy of products. Therefore, new technology is needed to distinguish legal products from illegal ones. In this paper, we present the ESD's requirements, characteristics and a new dynamic license management technology to prevent illegal copy.

Purpose - This study attempted to discover the impact of the Korea-China FTA(Free Trade Agreement) on electronic products distribution industry. Strategies will be provided to expand both countries' trade after the Korea-China FTA. Research design, data, and methodology - This study analyzed the differences before and after the Korea-China FTA, using an RCA(Revealed Comparative Advantage) index, TC(Technology Sophistication Index) index and TSI(Trade Specialization Index) that considered the FTA tariff situation. Data was collected from the International Trade Statistics Database and Korea, China Customs Service. Results - The results indicate that following the Korea-China FTA, China and Korea's bilateral trade of electronic products is expected to expand, and both countries will experience net welfare gains from the markets' expansion. Korea is competitive in several key products, although it faces competition from China. China's electronic products' competitiveness have indicated an increasing trend. Conclusions - The two countries should closely cooperate and communicate with each other. Ultimately, Korea should focus on high-tech, sophisticated techniques to gain market advantage. On the other hand, with the tariff decrease as well as the labor cost and labor force base, China will greatly be able to benefit from the manufacturing of medium- to low-end products in the future.

This paper discusses heat problem of IC, which composes the electronic instruments, to guarantee reliability of electronic instruments. And also proposes the unified equivalent model for various electronic instrument products to guarantee reliability and life of its parts. Because electronic instruments are down sizing and operated with high frequency, the internal temperature of electronic instruments is rising steadily. The internal temperature of the electronic instruments gives a big effect to electronic instrument's reliability and life. The semiconductor parts are the representative heat generation parts because of its complicated function, high frequency and high density. Consequently, guaranteeing reliability and life of electronic semiconductor is the important start point in securing the reliability and life of the electronic instrument product. Unfortunately, there are many factors, which affect heat dissipation efficiency. The heat dissipation efficiency follows the environment where the electronic instrument products are used. Therefore it is very difficult to define reliability and life of the electronic manufactures. Electronic instrument products are composed of printed circuit board (PCB), integrated circuit (IC), resistance, and capacitor and so on. And there are superposed thermal resistances, because the parts are arrayed on the printed circuit board (PCB), Therefore the total thermal resistance is variable. Consequently it cannot have same thermal model for each electronic instrument products. In the next part, we propose the unified equivalent model for various electronic instruments. And using the proposed equivalent model proofs the method for analysis reliability of electronic parts.

Nowadays a lot of high-tech electronic products such as TVs, monitors and camcorders are being developed. The more functions the electronic devices have, the more heat problems occur. Therefore, most of electronic products have air-ventilation holes to eliminate heat that is generated inside the products. The shapes of ventilation holes are usually complicated since aesthetic appearance of the products is important these days. In order to create those complicated shapes, designers should do time-consuming jobs because most of commercial CAD systems do not provide the functions that create patterns of lofted parts along freeform surfaces. In this research, an automated air-ventilation hole modeling system was proposed. The system generates patterns of lofted objects on freeform surfaces. Standard process to create air-ventilation holes manually was established, and vent-hole types and pattern types were classified into several categories. Designers can create many kinds of vent-holes by combining vent-hole types and pattern types. Users can also utilize user-defined pattern which can give users more flexibility. Developed system was applied to several design examples and the results are presented.

This study examined the effects of Korean celebrity advertising models on the advertising effectiveness for Chinese brands by comparing apparel products with electronic products. In addition, this study explored the effects of gender and monthly expenses on the evaluation of Korean celebrity advertising models. This study targeted 388 Chinese university students in China. The results show that Korean advertising models consist of five attributes (familiarity, visibility, credibility, similarity, and attractiveness) and that advertising effectiveness consists of three factors (attitude toward the advertisement, attitude toward the brand, and purchase intention). The impact of these five advertising model attributes on advertising effectiveness differ for apparel and electronic products. The results also indicate gender and expense differences in the evaluation of Korean celebrity models. We discuss the theoretical and managerial implications of the results along with potential limitations and future research directions.

In general, the distribution structure of marine products is very vulnerable to the uncertainties in the process from the production to the sale, and a lot of difficulty is thus inevitable in the supply control. Such a distribution structure is a very critical issue in securing the suability of marine products through systematic quality and hygiene control of marine products, and it is thus time to discuss the method to innovate and restructuring the distribution structure of marine products. From this point of view, this study approached the flow from production to consumption in view of SCM(supply chain management) beyond the partial discussion conducted so far for the distribution structure in the field of marine products. Further, this study suggested the establishment of electronic commerce systems with a traceability system built in RFID for marine products as an alternative of redesigning distribution infrastructure in the ubiquitous environment. From the results, we assured that such an electronic commerce system would be a new measure to improve the structure currently causing inefficiency and excessive distribution cost for the distribution structure of marine products.

Generally, heavy electronic products undergo many different types of shocks in transportation from a manufacturer to customers. Cushioning package is used to protect electronic products from severe shock environments. Since the mass distribution of heavy electronic products is usually unbalanced and complex. it is very difficult to design a cushioning package with having high performance by considering only the equivalent stiffness of that. Therefore, when designing the cushioning package for a heavy electronic product, it is necessary to optimize its shape in order to maximize the cushioning performance. In this study, it is focused on designing an optimal shape of cushioning package for a large refrigerator and an efficient design method is suggested by using a dynamic finite element analysis.
