In order to evaluate the evaluation of bi-national products, this study was classified according to product category similarity. In addition, by comparing the types of stores, we tried to suggest alternatives that can be practically applied to companies producing composite origin products. For this purpose, this study is applied to the analysis of bi-national product by product categories, such as public luxury, public luxury, private luxury, and private necessity, based on the psychological bases of consumers. The types of stores are divided into department store/direct store, outlet/discount store to elaborate measurement. As a result of the verification, it was found that brand evaluation and store evaluation had interactive effects depending on product type and store type. Specifically, in the case of public luxury goods, outlets/discount stores in both brand evaluation and store evaluation showed positive evaluation than department store/direct store. In the case of private necessity, there was no significant difference in brand evaluation, but in store evaluation, department store/direct store was confirmed that they had a relatively positive evaluation than outlets/discount stores. As a result, it was verified that consumers' evaluations can be changed according to the type of sales store for each product.

This paper investigated main determinants of purchase intention for VOD contents by employing an extended technology acceptance model. The findings showed that 'user activeness' is the critical external variable influencing five perceived belief variables, namely perceived usefulness, perceived playfulness, perceived quality, perceived complexity and perceived cost. Regarding consumer satisfaction for free VOD service, it had no direct effect but indirect effect on the purchase behavior, meaning that the satisfaction causes purchase intention for VOD contents via the cognitive attitude. Also, the moderating e!ect of use experience on the relationship between the belief variables and the purchase intention was confirmed. Users with much experience showed a higher perception for usefulness and quality, whereas users with less experience placed a higher value on the hedonic factors and costs. In contrast to previous studies on IPTV that mainly focused on determinant of IPTV subscription, this paper analyzed VOD that is a killer application of IPTV in identification of key factors for the acceptance. The findings provide IPTV operators some strategies to create customer value and improve profitability.

The light-emitting diode (LED) has been used in a variety of industrial fields and for general 0lighting purposes on account of its high efficiency, low power consumption and long lifespan. The LED is driven by direct current; therefore, an AC/DC converter is typically required for its use. An electrolytic capacitor is generally used for stabilizing DC voltage during use of the AC/DC converter. However, this capacitor has a short lifespan, which makes it a limiting factor in LED lighting. Furthermore, LED lighting requires a dimmable control to enable energy savings and fulfil a growing consumer demand. In this paper, the dimmable single-stage power factor correction (PFC) continuous conduction mode (CCM) flyback converter that employs no electrolytic capacitor is presented. The LC resonant filter is alternatively applied to reduce the 120[Hz] ripple on the output. And the optimum value of the LC resonant filter parameters considering both efficient and performance is analysed. Simulation and experimental results verify the satisfactory operation of the converter.

Since organized living cooperative associations sold their environment-friendly agricultural products directly to independent consumers in the past, the general distribution channels such as wholesalers had difficulty in handling these products. However, the ratio of distribution via wholesale channel has been gradually increased as consumption of environment-friendly agricultural products has expanded. This study is to address vitalization of wholesale distribution for environment-friendly agricultural products by gathering previous statistical data and analysis. In addition, statistical analysis are conducted by utilizing surveys on forwarders, consumers for environment-friendly agricultural products. As a result, the products producers ship are distributed through dealers at producers sites, producers cooperatives, or food process companies, food companies, internet shopping malls, large-scale distribution companies, consumer groups such as living cooperative associations, direct outlets at consumers sites, or exports. Among the channels, the large-scale distribution companies and franchised special shops account for 47%, the general supermarkets 15.7%, and living cooperative associations 14.6% respectively. By utilizing the research results on producers and consumers, and the distribution weight by channels for environment-friendly agricultural products, the distribution channels for living cooperative associations, wholesale markets, and large scale distribution companies are compared and evaluated. As a result, the level of producers' and consumers' satisfaction for them is the lowest since the low selling price for producers and high distribution margins.

As a direct-view flat panel displays, there are many devices, such as plasma display panels(PDPs), vacuum fluorescent displays (VFDs), and light emitting diode(LED). Among these, a PDP is the first type of panel display to be made commercially available. A 'Plasma display' is the general term for a flat display utilizing the light emission that is produced by gas discharge. However, the brightness and Luminous efficiency are still not adequate for consumer television. So, the new sustain electrode type of ac PDP was proposed. By arranging the transparent electrode of quadrangle by zigzag, the area of electrode are reduced, and the length of electrode gap is increased. It generates a high luminous efficiency(corresponding to a 40% improvement of standard type), the same discharge voltage characteristics, and the low power consumption at same luminance.

Purpose: Post-purchase service in online platforms has created an exciting focus for consumer behavior studies. This study intends to ascertain the impact of post-purchase shipping dimensions (shipping service, tracking service, return service, and customer care) on customer satisfaction and behavior intention. The authors developed a new model considering behavioral intention as the endogenous variable integrated framework of previous studies. Research Design and Methodology: The total sample is 223 respondents, selected using purposive sampling. The data collection uses Google Forms and is analyzed using AMOS Structural Equation Modeling (SEM). Results: Our findings showed shipping, tracking, returns, and customer service positively impact customer satisfaction, and customer satisfaction mediates shipping, returns, and customer service on customer behavior intent. Furthermore, customer satisfaction does not affect the effect of tracking service on customer behavior intention. Conclusion: Our hypothesis of the relationship between the post-purchase dimension and customer satisfaction was supported. However, only two of our three mediating hypotheses are supported. The mediating effect of customer satisfaction on the post-purchase dimension on behavioral intention is insignificant, while their direct relationship was significant. It showed that, concerning tracking service, customer satisfaction is not a requirement for the customer to perform behavioral intention in an e-retail context.
