  • This study investigated the factors in evaluating internet shopping mall sites, and developed a self-report evaluation scale of such sites, This article identifies factors to determine criteria for evaluating the sites from the consumers' viewpoint. Eighty three items were extracted initially, which were then categorized as follows: \circled1 Type of business, \circled2 Navigation ease, \circled3 Technological level, \circled4 Design of sites, \circled5 Communication ease, \circled6 Information available, \circled7 Ease of access, and \circled8 Site security, Overall reliability coefficients were high in the individual domains ($\alpha$=.86 to $\alpha$=.95). Face validity and contents validity were demonstrated to be good, There were significant differences in the means of these categories. The results also show that the technological level is the most important in shopping mall sites evaluation. These results may be used not only as a tool to evaluate shopping mall sites but also as a guideline to improve the quality of a shopping mall site that is under development.

  • Anterior spacing is one of the interesting phenomena in clinical orthodontics and presents difficulties in determining the etiology and the retention method. Only through the careful examination can orthodontists reach the correct diagnosis and treatment plan and every orthodontist should get rid of the cause to obtain good results. The author considered about the treatment and the retention method of the anterior spacing according to etiology and presented two eases of anterior spacing. In the first ease, the etiology was simple arch length discrepancy with excessively protruded anteriors. In the second ease, the etiology was the same as the above but the patient had the tongue thrusting habit. Both the eases showed the thin fibrous tissue bands between the upper central incisors but only the second case was thought to be associated with this tissue. The permanent retention loop which is non-surgical was applied to the ease and the results were acceptable.

  • 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.

  • Despite their potential value, the mobile Internet services in the domestic market have not been widely accepted as industry experts have expected. To understand why, this study uses the TAM, Technology Acceptance Model, and explores the factors affecting the usage behavior of the end-users. Based on statistical analysis of survey data, we show that social influence and perceived ease of use affect perceived usefulness, and that self-efficacy and focus significantly influence perceived ease of use. Furthermore, perceived usefulness is shown to play a significant role in explaining actual usage of the mobile Internet services. However, contrary to the hypothesized relationships, service quality, focus, and innovativeness of users turn out to have little impact on the traditional endogenous TAM variables such as perceived usefulness, perceived ease of use, and actual usage behavior. Based on these results, we attempt to provide managerial implications for the domestic mobile Internet service providers and to suggest future research directions in this domain of research.

  • The objective of this study is to explore the effects of e-teaming users' self-efficacy and perceived service quality for e-teaming staffs such as instructors or teaching assistants on two main perceptions for e-learning systems in a view of information technology - perceived ease of use and perceived usefulness which have been considered as important antecedents for acceptance of information technology so called in Technology Acceptance Model. For this purpose, we suggest a research model and test it empirically by sampling in students of virtual universities. In result, all hypotheses except the relationship between academic self-efficacy and perceived usefulness are accepted. This result implies that self-efficacy for computers and service quality for staffs such as instructors or teaching assistants should be considered as important ones for success of e-learning systems in addition to those related with information technology.

  • Purpose - This study aims to provide a brief understanding of usability and its extended models with TAM as well as identifying additional determinants that had been suggested in previous studies on mobile services. Research design, data, and methodology - Empirical data were collected by conducting a field survey of potential mobile application service users. The call for participation was also made in mobile related application issues, which were widely discussed. Result - The ease of use and usefulness had a significantly positive influence on attitude and intention. It also was revealed that added value services can offer practical value to customers. Thus, positive attitudes toward the adoption of services by customers are present when they perceive higher usefulness and ease of use of mobile application services. Conclusion - It was indicated that customers who are more inclined to try new products or who have a higher demand for new things tend to think about those functionalities and added value mobile application services from the perspective of usefulness and ease of use and operation.

  • One of the basic goals, when considering networks for communication in industrial control applications, is the reduction of complexity of related wiring harnesses. In addition, the networking offers the advantages for industrial control applications, such as ease of cabling, ease of changes in the cabling, ease of adding controller modules, etc. CAN (Controller Area Network) is generally applied in car networking in order to reduce the complexity of the related wiring harnesses. These traditional CAN application techniques are modified to achieve the real time communication for the industrial control applications. In this paper, we propose the method of CAN Identifier assignment for Real-Time network system. This method is can be used to scheduling messages on CAN for Real-Time network system. And also, the real-time network system is developed and the proposed moth(Ids are verified experimentally.

  • This study investigates internet shopping behavior of consumers. The rapid growth of the internet shopping markets is solely dependent on the voluntary adoption of internet shopping medium by the personal users. But the studies on this topic are very limited. Based on these facts, this study, recognizing the internet shopping medium as an innovation, studies how consumers understand and use innovative internet shopping medium by applying and extending the technology acceptance model proposed by Davis et. al.(1989). The results of the survey on 947 consumer panel reveal that compatibility, system quality have positive impact on the formation of perceived ease of use. And it is also shown that the perceived ease of use, system quality, and compatibility have positive influence on perceived usefulness, but computer-efficacy has no effect on perceived usefulness. Meanwhile, it is confirmed that perceived usefulness and compatibility have positive effect on attitude toward internet shopping behavior, but perceived ease of use has no effect. In addition, perceived security and social norm, as opposed to the hypotheses, are shown to have no effect on internet shopping behavior. Lastly, applications and related limitations are discussed.

  • This paper examines user's loyalty to social network sites (SNS) from switching costs (SC) incurred by both technology and social factors. We propose a research model specifying that the perceived values of resources of the factors affect the SC and the SC determine user's loyalty. Empirical results show that technology variables of ease of use and privacy controllability, and social variables such as network size, usefulness of SNS activities, and awareness of network status have significant effect on SC. In particular, ease of use is negatively associated with SC. Since it is shown that in overall the impact of social factors is stronger than that of technology factors, we can interpret that technological superiority itself does not lead to the success of SNS. Contributions of this paper are: 1) application of SC in SNS research from the resource based perspective, which can be used for developing strategies of sustainable SNS, and 2) provision of different perspective toward the variable of ease of use, which has been considered an important factor of technology acceptance.

  • In this study, we identified the characteristics of mobile fashion shopping and verified the path model of effects of these characteristics on mobile fashion shopping purchase intention through perceived usefulness and perceived ease of use. We conducted the survey targeting smartphone users in their 20s~30s and analyzed the structural equation model using AMOS 16.0. The results were as follows: Mobile fashion shopping characteristics (enjoyment, credibility, instant connectivity, security, and personalization) had positive effects on perceived usefulness and perceived usefulness influenced attitude toward purchase and purchase intention positively. Attitude toward purchase affected purchase intention in a positive way and perceived usefulness had indirect effect on purchase intention through attitude toward purchase. In conclusion, we proposed the marketing strategies of the mobile fashion shopping businesses.
