This paper explored the use of an algorithm for the data mining and method in handling missing data which had generated enhanced association patterns observed using the data illustrated here. The evaluations showed that more association patterns are generated in the second analysis which suggests more meaningful rules than in the first situation. It showed that the model offer more precise and important association rules that is more valuable when applied for business decision making. With the discovery of accurate association rules or business patterns, strategies could be efficiently planned out and implemented to improve marketing schemes. This investigation gives rise to a number of interesting issues that could be explored further like the effect of outliers and missing data for detecting fraud and devious database entries.

This paper focused on empirically testing the ESM(Electronic-Store Success Model). The model was developed by basing upon the ‘Updated D&M(DeLone and McLean) IS Success Model(2003)’ and reflecting the characteristics of marketing and e-business, and composed of the six dimensions including system quality, information quality, service quality, trust, customer loyalty and financial performance. The research model consisting of five dimensions, excluding financial performance, was proposed and empirically verified by structural equation model with respect to data from 224 customers on 69 Electronic-Stores. The results show that system quality and information quality significantly influence service quality, and that service quality also significantly influence trust and customer loyalty, and that trust has significant influence on customer loyalty.

There are numerous researches being studied regarding Electronic Commerce (EC), that is one of the hottest issues for the 21 century in the various areas such as management, engineering and science; etc, This paper concerns the logistics functions which are essential for completing a commerce process even under the EC environment. Even though both the traditional and the electronic commerce via internet share many common problems regarding logistics, new logistical issues are generated as the EC is being popularized. We study the logistics competitiveness under the EC environment and provide ways to improve the logistical performance. We first point the emerging logistical paradigm to check the issues under EC. Next, logistics competitiveness factors are provided. Finally we propose several ways for the logistical performance and cost perspective.

In this paper, we describe the basic operating mechanism of our novel reflective display, Fast Moving Ball Actuator (FMBA) mode[1], using micro-sized metal coated polymer ball in fluid medium. Metal surface of the ball can be charged up by contact electrode and their locations can be controlled by applied field to obtain optically on and off state. In the medium with high viscosity, the response speed of the moving ball might be reached into their terminal velocity and changed in proportion to the frequency of applied voltage on the electrodes.

Although the research on electronic commerce is plentiful, there is little empirical research related to Web-Based Shopping Systems (WBSS). This is especially so in global electronic commerce circumstances. WBSS are the fastest growing segment of digital economies and are perceived as driving forces of electronic commerce in terms of global markets and digital business. Using WBSS, organizations have a new chance of their business evolving successfully as global marketers. This paper develops a unified model to assess the diffusion of WBSS. Factors that impact WBSS diffusion are identified and analyzed as the basis for empirical testing. A set of propositions is developed that allows operationalization of the model. The ultimate goal is to provide the new research insights for the academic circles and the practical guidelines for organizations wishing to undertake WBSS.

The purpose of this article is to study on the strategy for Success in the Electronic Trade Transaction. The term "electronic trade" means all or part of any such trade as implemented by means of apparatus having the information processing capability, such as a computer, and networks of information and communications. The Internet brings people together from every country in the world. It reduces the distances between people in many ways. The predominant language on the Web is English, although sites in other language barrier is overcome, the technology exists for any business to conduct electronic commerce with any other business or consumer, anywhere in the world.
