The purpose of this study is to reveal their satisfaction procedures from users of information service expectation-disconfirmation theory. To achieve this goal, we use the NDSLQual model to measure the quality of NDSL service. The results were as follows: First, while the expectation has a negative effect on the expectation-disconfirmation, it has a positive effect on the perceived performance. And perceived performance has a positive effect on the expectation-disconfirmation. Second, the expectation-disconfirmation has a positive effect on the overall satisfaction and loyalty. However the explanatory adequacy of the regression model is very low. Third, perceived performance has a positive effect on the overall satisfaction and loyalty. In order to increase the overall satisfaction and loyalty for NDSL, it is necessary to seek ways to improve the perceived performance and lower the expectation-disconfirmation.

The purpose of this study was to design a PCSI model that can be applicable to measurement of library user satisfactions, which can be used in evaluating organizational performance. The National Assembly Library (NAL) was selected as a case to design a PCSI-based model and to test the model by conducting a self-administered survey of 341 internal and external library users. The model was validated to have a satisfactory model fit. Fitting the model, the study confirms that the service qualities of the NAL affect user satisfactions, which in turn affects organizational performances. The PCSI score of the library was 80.4, which can be used as a useful index that can compare the library's performance with other organizations in the similar public domain. Major contributions of this study are two-fold: the PCSI-based model proposed in this study provides a theoretical basis that assesses organizational performance of libraries via user satisfaction; and libraries can utilize the model as a management tool to assess the organizational performance from the user perspective.

This Study explores the reason why the social media like Cyworld, Iloveschool in Korea in the viewpoint if the layered model by interview. As a result the success factor in the viewpoint of layered model, user used social media for fulfilling the need for linking with other users and the social media offers the customized contents to user. Finally the social media dominated the market in advance. Facebook and Kakao talk are good examples of successful media. The failure factors are to care less about what other users want, to limit the expand of platform and not to copy with the change of the media environment. Iloveschool, Cyworld and Twitter are the examples of failure social media in Korean society. This study highlights the importance of the sensitivity of the change of environment. The expert mentioned the importance of 4th industrial revolution technology like AI, Big data and expected that new technology will emerge and the service will be developed by the change of user's taste.

With the rapid advances in automated driving technology, opportunities to experience automated driving directly or indirectly are being provided to the public. On the other hand, research on the preferred automated driving patterns from the user's perspective has not been conducted in Korea. This study used a driving simulator and an experimental vehicle capable of automated driving to evaluate the user satisfaction regarding longitudinal and lateral accelerations. Automated driving patterns were implemented in a virtual environment simulation using five values of longitudinal and lateral accelerations derived from driving experiments. Among these values, three were implemented through experimental vehicle-based automated driving to evaluate satisfaction and anxiety. The participants evaluated lateral acceleration more sensitively than longitudinal acceleration and showed higher levels of anxiety. Based on these results, the necessity of user-oriented evaluation research for automated driving patterns and the suitability of simulator-based evaluation methods were presented.

This study examines the status of Korean E-government implementation and explores the ways to contribute to governance improvement by means of the e-government. As far as the level of implementation of e-government, Korea is confirmed to have achieved upper level by global standards, but it is found that continuous efforts of improvement is still required in the area of integrative management, which is considered as a final phase of e-government development. In order to evaluate how much e-government of Korea has contributed to the improvement of governance, I tried to measure the usability of e-government from the perspective of providers and that of consumers, and also, a qualitative evaluation on the provision and usage of functions related to the governance was also adopted. It is concluded that, while Korean e-government has reached a remarkable stage in the quantitative perspectives, there are still a room for improvement from the qualitative perspective, such as its role as a means of governance improvement. Also, based on the above evaluations and consequent findings, I suggest guidelines for the improvement of governance through the development of e-government.
