Social Network Service is a web-based service that allows the people to construct relationship among users with same interest and supports various activities such as managing personal relations and sharing information or contents. Based on the IS Success Model and UTAUT model, this study examines factors influencing the satisfaction of SNS use. Questionnaires are collected from 473 students who are using the SNS. The results are followings: first, the performance expectancy, effort expectancy and social influence have positive effect on the use intention. Second, the facilitation conditions and use intention have positive effect on the use. Third, the system quality, information quality and use have positive effect on the satisfaction. Fourth, the performance expectancy is the strongest predictor of the use intention, the use intention is the strongest predictor of the use and information quality is the strongest predictor of the satisfaction.

In this study, land use state analysis for northern part of Cheon-ra province where is relatively vast area is accomplished using the application system of land use map. The system is developed for promoting application of the latest land use map and is possible to GIS spatial analysis. Through this study, an analysis method of land use state and decision making support for effective land use plan is presented. It is expected for land use map to be variously applied to land planning by analysis of wide-range land use state and base data for fields such as environment effect, disaster analysis.

The purpose of the present study is to verify the structural relationship among system quality, information quality, service quality, perceived ease of use, perceived usefulness, satisfaction, intention on continuous use of mobile learning in cyber university. For this study, W cyber university in Korea was chosen to conduct web survey. The subjects were 283 students who participated in W's cyber university courses. A hypothetical model was composed of system quality, information quality, service quality, perceived ease of use and perceived usefulness as exogenous variables, satisfaction and intention on continuous use of mobile learning as endogenous variables. The result of this study through structural equation modeling analysis is as follows: First, information quality only affect satisfaction, Second, perceived ease of use, perceived usefulness and satisfaction significantly affect intention on continuous use of mobile learning. These results imply that information quality should be considered for the design and development of mobile learning contents. Also, perceived ease of use, perceived usefulness and satisfaction is important to enhance intention on continuous use of mobile learning. This study proposes strategies for successful mobile learning in cyber university.

Pseudolite (PL) is a kind of signal generator, which transmits GPS-like signal at the ground. However our own made PL is different from a GPS satellite in clock accuracy. GPS satellites are synchronized by use of high precision atomic clocks. But because our PLs use low cost temperature controlled oscillators (TCXO), so it is very difficult to synchronize them. Hence, we should install reference station and use Differential GPS (DGPS) algorithm to calculate user position. By use of this method, we already developed indoor navigation system a few years ago. We named it as 'Asynchronous Pseudolite Indoor Navigation System'. However, this system requires that sampling times of all the receivers...

Business-to-Business electronic commerce websites are a common form of inter-organizational systems that span organizational boundaries and enables organizations to exchange information in a seamless fashion. To reap the desired benefits it is important that the website be used in the intended manner. The level and extent of use of a business-to-business website depends partly on the inclination to use the website by the users in the primary organization and in the user organizations independently and the combined inclination of the organizations together. This combined inclination is referred to as the System Inclination, with dominance playing a key role. Each organization has certain characteristics of its own and may differ significantly in their inclination to use. It is important to analyze the factors that determine this inclination to use, so that organizations can adopt appropriate management mechanisms to control it. This paper proposes a framework to explain the organizational factors and their influence on the inclination to use a website, based on study of four Indian buyer-supplier dyads. Inclination to use is found to be influenced by factors like top management support, website characteristics, adequate support mechanisms, user group orientation towards electronic commerce and basic IT drive among the employees, at both the primary and user organizations.

This study deals with the concept of Microcomputer Playfulness(MCP), Even though MCP was introduced recently in the MIS research, the concept is expected and empirically supported to be significant in explaining information technology adoption and usage. Based on the Technology Acceptance Model(TAM), this study presented a revised model to explain individual PC use and explored the role of MCP in PC use. The results showed that MCP has a direct influence on PC use rather than a mediator between Self-efficacy and PC use, and that MCP is a better predictor of PC use than Computer Anxiety.

The purpose of this study is to grasp a concept for mixed-use tendency of educational facilities, its propellant circumstance in the nation and japan, to analyze a feature of a function, a flow planing of user and the complex form which appear from an instance of the mixed-use tendentious educational facilities and is to suggest a basic matter on the architectural planning for mixed-use tendency of the regional facilities and educational facilities. The results of the study can be summarized were as follow: 1) The step of mixed-use in nation is yet the early step and a extremely feeble to compared with the japan. 2) In a case of the mixed-use tendency facility, the nation is to appear for the necessity of a region but they know of a varied facility to be mixed-use tendency in japan. 3) Much to appear monolithic form in the side of complex form. 4) To appear multi-story in the side of facility-story. 5) It is much example of separating from main entrance, the flow of interior found of dividing into not to transit or transit by the function of facility. 6) To know for being tendency of common and division by the principal of user in facility instituting E V.

The technology acceptance model(TAM) has been widely studied in IS research and Internet has been expanded very rapidly in modern society. The purpose of this study is to provide an internet acceptance model and test it empirically. This study extends the TAM model and motivation theory by adding gender. This model posits that perceived ease of use, perceived usefulness and perceived playfulness correlate with Internet use, Test results are as follows: First, the survey suggested the three factors-perceived usefulness, perceived ease of use and perceived playfulness-affect the use of Internet. Second, Difference just appeared in case of perceived use of use between genders but not others-perceived usefulness and perceived playfulness. Third, the result represented that there was nothing that affected the use of Internet by itself among the three factors-perceived usefulness, ease of use and playfulness and perceived usefulness used gender as a moderated variable in the case of the use of Internet.

Purpose: This paper is to analyze motivation and behavior of alcohol use of employees, and effects of social pressure on alcohol use of employees. Methods: A cross-sectional study was performed with 341 employees in Industrial Complex. Data were collected from June 26, 2007 to July 11, 2007. Collected data were analysed through Frequency, ANOVA, One-way ANOVA test. Result: Social motivation showed the highest mean among motivation of alcohol use, man showed higher mean than woman on confirmity motivation and affirmation motivation. Dangerous alcohol use showed the highest mean among behavior of alcohol use, man showed higher mean than woman on behavior of alcohol use. Effects of peer showed higher mean than effects of family, generally the more high effects of peer is, the more higher confirmity motivation, dangerous and dependent alcohol use showed. Conclusion: Therefore, to decrease alcohol use of employees must be prepared an alternatives to change drinking culture and recognition, and developed for working man and individual workplaces.
