Mobile Instant Messenser (MIM) Market With the market is enlarging and attracting more and more companies. With the market expanding and number of users increasing, the competition in this area will be fierce. In order to gain competitive advantage, it is important to develop a strategy to maximize user value and to grasp the continuous usage intention of users. However, there are currently not enough researches done in this field. Therefore, this paper to study the effects of network externalities and perceived experiential value on perceived usefulness, user satisfaction, and continuous usage intention. The research results showed that the perceived experiential value and vertical compatibility significantly affected user satisfaction, but the perceived network size did not. The perceived network size and vertical compatibility did not affect the perceived usefulness. Also, the economic value, which is a sub-factor of the perceived experiential value, did not affect the perceived usefulness, but the functional value and hedonic value did significantly. The perceived network size significantly affected continuance usage intention, but the perceived network compatibility did not.

The survey was based on an interview of merchant establishments and the views of the merchants and was not based on their financial data. As a first step, the variables used in the survey were tested for interdependence using Chi-square tests; subsequently data reduction using factor analysis was performed and finally linear regression to establish a relation between dependent and independent variables. Merchant establishment believe accepting credit cards and increasing volume is costlier compared to another form of payment, but have mixed awareness about interchange fee. It also indicated that interchange fee and cardholder benefits are independent of the merchant establishments.

Using SPSS 20.0 and AMOS 20.0 package, Cronbach's ${\alpha}$, a confirmotory factor analysis and a structural equation modeling analysis were performed. The results are as follows. Hedonic, economical efficiency and interaction without information provide subjective norms significantly influenced the purchase satisfaction. And aforementioned subjective norms significantly influenced repurchase intension, too. The purchase satisfaction positively influenced the repurchase intension. Therefore, social commerce sellers of fashion products ought to offer variety price benift and promotion to raise the purchase satisfaction and repurchase intension. To offer variety price benift, they should respond sensitively to the price set by comparing prices with other sellers. And promotion to raise the purchase satisfaction and repurchase intension need to consider such variety of missions, discount coupons or event and mileage. In addition, they should develop customer service system for interaction with customer and connect to the repurchase increases the purchass satisfaction through faster customer response to the product information or sales, service.

This study is designed to predict the overall electric power load, to apply the method of time sharing and to reduce simultaneous load factor of electric power when authorized by user entering demand plans and using schedules into the user's interface for a certain period of time. This is about smart grid, which reduces electric power load through simultaneous load factor of electric power reduction system supervision agent. Also, this study has the following characteristics. First, it is the user interface which enables authorized users to enter and send/receive such data as demand plan and using schedule for a certain period of time. Second, it is the database server, which collects, classifies, analyzes, saves and manages demand forecast data for a certain period of time. Third, is the simultaneous load factor of electric power control agent, which controls usage of electric power by getting control signal, which is intended to reduce the simultaneous load factor of electric power by the use of the time sharing control system, form the user interface, which also integrate and compare the data which were gained from the interface and the demand forecast data of the certain period of time.
