This study has two research objectives related to end-user computing (EUC). One of the research objectives was to investigate the current status of EUC of Korean firms. Another research objective was to examine the relationship between individual differences of end-users and EUC success. Using survey data from 752 end-users of 23 firms, the surrent status of EUC and the relationship between individual differences of end-users and EUC success were investigated. The current status of EUC was examined from six perspectives: 1). what is the characteristics of EUC strategy of Korean firms, 2). what are the individual characteristics of end-users in Korean Firms, #0. what are the characteristics of tasks performed by end-users using computer, 4). what are the application a areas of EUC, 5). How end-users are satisfied with the support of firms, 6). what are system usage and satisfaction of end-users. It was also foud that individual differences of end-users are related to EUC success. More specifically, it wat shown that the male gender, younger age, higher level of education, higher rank and organizational tenure, higher math ability, thinking type of cognitive style, positive and optimistic attitudes toward computer, more experience with computer, more computer education and knowledge are individual differences variables associated with EUC success. The results of stepwise regression analysis suggested that the individual difference variables accounted for 14%, 25%, 39% and 30% of the variances of four EUC success variables, satisfaction for outcome, satisfaction for ability, frequency of computer use, and the number of tasks, respectively. These empirical findings suggest that EUC managers should consider individual differences of end-users in managing EUC, such as education, training, support, and human resource management, to maximize potential benefits of EUC.

This research wanted to examine what narratives and discourse were being formed in web drama contents young generations were going crazy about. To understand the characteristics of such love epics and to know what narratives were being formed based on narrative structures and comments, this research specifically used the web drama produced up to the season 4 for the first time in Korean web drama history with a large number of accumulated views. It was found that the narratives of the drama composed the romantic relationships of four couples as independent episodes, and realistically highlighted separations and reunions of those couples, and suggested concrete methods to solve agonies and conflicts they would experience in such relationships. And, in user comments, there emerged relational narratives confusing friendship and love between partners of opposite sex, narratives regarding the third person as enemy, and narratives on typical sex roles in such romantic relations. And, the culture seeking subjective love style and sharing and sympathizing with the love histories also appeared.

Currently, virtual reality contents using VR images are spotlighted since they can be easily created and utilized. But because VR images are in a state of lack of interaction, there are limitations in their applications and usability.In order to overcome this problem, we propose a new method in which 360 degree panorama image and game engine are utilized to develop a high resolution of interactive VR service in real time. In particular, since the background image, which is represented by a form of panorama image, is pre-generated through a heavy rendering computation, it can be used to provide a immersive VR service with a relatively small amount of computation in run time on a low performance device. In order to show the effectiveness of our proposed method, an interactive game of a virtual zoo environment was implemented and illustrated showing that it can improve user interaction and immersion experience in a pretty good way.

With the development of information technology, users can freely search records and archives without the involvement of archivists. However, existing records retrieval systems show only partial search results, which do not consider the users' intention. To overcome this problem, semantic web technology is being developed, and the International Council on Archives (ICA) is working to develop RIC (Records In Context), a new archival description standard, which reflects the trend. The conceptual model for archival description and its ontology of RIC are the basis for implementing semantic-based retrieval. In other words, it is necessary to consider the viewpoint of the users on how the records retrieval based on meaning should be designed and provided. Therefore, this study selected three cases of systems, which are built as semantic web technology, and conducted interviews of the users for the evaluation of the systems based on user experience. This study proposes the kind of interface that can be implemented for the ontology-based record retrieval system.

Korea is facing various social problems including single elderly household, increase in the number of disabled people and poverty rate and a difference in the proportion of males to females between urban areas and rural areas along with the advent of rapid aging society. Especially, the ratio of poor households in rural areas residing in housing which falls below the minimum housing level and most of them are in the dead zone of housing welfare. In addition, if it is impossible for them to move (relocate) to new housing, the house remodeling is the only measure for improving their housing welfare. However, we don't have enough prior relevant academic and practical experience, and house remodeling requires a series of process including prior planning construction and post-occupancy evaluation, but almost no fundamental research that provides relevant insight has been carried out. Therefore, the purpose of this study is to describe all field situations that occur in the whole customized house remodeling process for disabled female senior citizens living alone in a rural area. The remodeling process was classified into initial planning stage, field verification and adjustment stage and construction stage as the method to participate in the field directly, and any change in the remodeling plan and its causes at each stage were analyzed. As a result, some remodeling items were changed from the main viewpoint of participating parties before the beginning of construction and for reasons such as the deterioration level of housing site, limitation in building equipment and rearrangement of housing, etc., and the remodeling method and its details were developed. It was identified that constant change that occurred in the remodeling process resulted from 1) unique poor characteristics of existing housing and 2) physical condition of residents and their unique lifestyle characteristics that were two aspects required to be emphasized by customized remodeling.

Compared with traditional face-to-face instruction, online learning causes learners to experience more severe feeling of isolation and results in higher dropout rate. This is due to the lack of interaction, sense of belonging, membership, interdependency, cooperation among members and social environment that enables persistence in online learning. Therefore, it is very important for grouping e-learning community to lower the dropout rate and eliminate feeling of isolation. In this paper, the research has been done on the inclination test list to be applied for grouping the desirable learning community. And on the basis of this research, the grouping system for e-learning community(GSE) based on intelligent multi agents for an inclination test using homogeneous and heterogeneous items has been developed. GSE system has such properties that construct a personalized user profile by an agent, and then make groupings according to users' inclination. When this system was evaluated, about 88% of learners were satisfied, and they wanted the group not to be disorganized but to be maintained.

Digital tourism is the digital support of the tourist experience before, during and after the tourist activity[1]. The GPS-enabled mobile phones provide location-based mobile applications such as tour guide and storytelling services. In this paper, we propose the smart tour guide service platform based on GIS and develop the mobile application to provide the smart tour guide service. The proposed smart tour guide service platform consists of CMS, the multi-modal navigation system, the tour attraction content creation and management system, the tour commodity creation and management system, the smart search system, and the user terminal. The smart tour guide application supports digital tourism in the pre-tour, during tour, and post-tour using the proposed smart tour guide service platform in the popular tourist attractions in Jeju.

In the past, design has been recognized as a means to determine colors, shapes, and functions Recently, however, it has been accepted in a wider sense, namely designing the entire service, including product and user experience design. In this way, in addition to creativity and expressive power that designers have as their main competence, according to the expansion of this design object, designers are required to have comprehensive abilities in related fields and accompanying technical professional abilities. If designing as a technology application as a direction toward this situation, design education can be carried out by approaching technology as a method of expression or design subject. It can also be an effective alternative towards improving the understanding of technology. Meanwhile, many small microcontroller board products with advanced functions and multi-functional specialized programming integrated development environments (IDEs) are becoming widespread due to their open source, low cost, and scalable features. However, students in the design department who lack the basic knowledge of science and engineering have difficulties learning, which requires considerable time and is required for practical use. From this point of view, we have made advancements in the technical understanding of design education by conducting fundamental research to the effectiveness of microcontroller-based prototyping tools as means of expression. We also conducted basic education of microcontroller boards for a certain period of time on students who majored in design in conjunction with the basic survey and investigated the obstacle factors using a questionnaire. Through these surveys, we have confirmed the necessity of designing microcontroller boards of low difficulty, which simplify the coding process that can act as a barrier in difficulty for design students to apply smoothly in design education. In addition, we intend to carry out a basic study on the guideline of microcontroller design for design education and composition of education programs.
