  • This study investigated the user's attitude to the nature trail called Gubulgil in Gunsan reservoir area and evaluated the quality of user's satisfaction of the trails and their facilities by importance-performance analysis (IPA). User's evaluation was achieved through questionnaire survey and total 283 pieces of subjects were used for the analysis. The results are as follows. Firstly, importance value of circularity of trails was very high, and it has great implication to ordinary trails which connect ecological, historical and cultural spots routinely and linearly. Secondly, through the IPA, relatively dissatisfied attributes were parking lots, direction boards, storytelling, convenient facilities and encountering of wildlife. Expansion of parking lots can cause the environmental disruption, so running a shuttle service from Gunsan downtown to the reservoir at weekends can be more reasonable. In case of ecological and historical information delivery, softwares like storytelling contents with sense of realism as well as hardwares of informative signboards are very important in nature trails. Encountering wildlife in trails is fascinating experience but it means visitors may disturb wildlife habitats. So route design should be done very carefully not to intrude their territories.

  • We consider three different secure broadcasting scenarios: i) Broadcast channels with common and confidential messages (BCC), ii) multi-receiver wiretap channels with public and confidential messages, and iii) compound wiretap channels. The BCC is a broadcast channel with two users, where in addition to the common message sent to both users, a private message, which needs to be kept hidden as much as possible from the other user, is sent to each user. In this model, each user treats the other user as an eavesdropper. The multi-receiver wiretap channel is a broadcast channel with two legitimate users and an external eavesdropper, where the transmitter sends a pair of public and confidential messages to each legitimate user. Although there is no secrecy concern about the public messages, the confidential messages need to be kept perfectly secret from the eavesdropper. The compound wiretap channel is a compound broadcast channel with a group of legitimate users and a group of eavesdroppers. In this model, the transmitter sends a common confidential message to the legitimate users, and this confidential message needs to be kept perfectly secret from all eavesdroppers. In this paper, we provide a survey of the existing information-theoretic results for these three forms of secure broadcasting problems, with a closer look at the Gaussian multiple-input multiple-output (MIMO) channel models. We also present the existing results for the more general discrete memoryless channel models, as they are often the first step in obtaining the capacity results for the corresponding Gaussian MIMO channel models.

  • This research conducted a survey targeting mobile SNS users in order to see whether mobile SNS attribute( accessibility, usefulness, newness, connectivity) through the medium of information share and relationship formation had a positive influence on user satisfaction. The results of the analysis showed that usefulness and accessibility had a significant influence on information share, while accessibility and connectivity had a significant influence on relationship formation. Information share and relationship formation both had a significant influence on user satisfaction. Based on this research, an angle of approach different from the business transactions and information services offered in existing mobile networks is necessary when corporations provide SNS through mobiles. When considering that the most important part in the use of mobile SNS is the social component, this can be actively used for the development and marketing of SNS services. Therefore, the SNS provider must focus its efforts on finding a method to stimulate user sensibilities in order to increase customer satisfaction and draw out continuous usage.

  • This study is intended to suggest an improvement scheme of activating container multiplex cultural space through an analysis of container architecture characteristics and a survey of user satisfaction, focusing on container multiplex cultural space located in Seoul city. Hence, the elements of multiplex cultural space and the characteristics of container architecture were deduced and analyzed through precedent study and literature review relating to multiplex cultural space and container architecture, and then an analysis framework was established with items to measure the user satisfaction. Based on this, a questionnaire was created, and users were surveyed through on-site visit. The results of analyzing the container multiplex cultural space users' satisfaction are as follows. First, in order to increase user satisfaction, it is necessary to highlight visual element. Second, there is necessity for distinct space configuration, such as connection, stack and extension by utilizing the fixed specifications, the characteristics of container. Third, there is necessity for extended space where people feel a sense of openness. Fourth, it should be improved so that air is well circulated by installing glass, operable window, etc. In further research, it is thought necessary to make a study of commercial space and facilities inside university besides multiplex cultural space.

  • Multimedia systems present information by various media, for example, video, sound, music, animation, movie, etc., in addition to the text which has long been used for conveying the information. Among many multimedia applications, the multimedia information retrieval systems commercialized in the forms of multimedia encyclopedia CD-ROMs, benefited from various media for their ability to present information in an efficient and complete way. But using several media, on the other hand, may cause end users' confusion and furthermore, poorly designed user interface often exacerbates the situation. In this study, the multimedia systems were studied from the standpoint of usability. The conceptual framework of the user interface of the multimedia system was newly defined. And 100 initial variables for user interface design of general multimedia systems were suggested through literature survey and expert opinions based upon the framework developed. Among various application areas, the multimedia information retrieval systems were chosen for investigation, and 36 variables particularly relevant to user interface of the multimedia information retrieval systems were selected. According to the sequential research strategy, the variables that were considered to be most important were finally selected through a screening stage. A part of selected variables were verified through a human factors experiment as the first step of sequential research. Based upon the result of the experiment, guidelines for user interface design were provided. For future study, the variables remained will be Investigated and the study will expand to another application areas.

  • The subject of this study is user experience analysis for OTT mobile app services. Application service quality was quantitatively measured by utilizing KS-eSQI evaluation model from a service quality perspective. The purpose of this analysis is to analyze how service reuse and other people's intention to recommend services are affected by service quality. In addition, further analysis of user experience will qualitatively look at what efforts are needed to improve OTT service quality and provide a user-friendly environment. According to the survey, the higher the level of KS-eSQI service quality, the higher the reuse of OTT services and recommendation of others. In particular, the dimensions of primary services and unexpected additional services had a higher impact on customer loyalty and recommendation of others than in other industries. Moreover, the following three implications were found to improve app services from a customer experience perspective. First, images and video thumbnails that highlight the strength of the content they provide should be actively utilized. Second, it is necessary to provide service companies with evidence for data-based work recommendations. Third, it should provide a viewing environment in which users can respond more intelligently to the various situations and conditions when they actually watch.

  • There has been a significant paradigm shift in the book industry from print to digital, with the increased use of electronic books (e-books) on e-book readers. The major online booksellers and publishers are devoting their energies to the growth of the e-book market, resulting in an upward spiral in e-book usage, and a resultant increase in the number of downloaded e-books in an e-book reader library. However, there are comparatively few features for e-book management and search in most e-book reader libraries, particularly in smartphone environments. In addition, the user interfaces of e-book management in e-book readers are highly diverse, which has led to major usability issues. In this paper, we analyze user preferences for e-book management and search in the libraries of the five most commonly used e-readers for the Android smartphone platform via a questionnaire survey. Then, we suggest ideal alternatives in addition to user-friendly features based on user preferences for managing e-book libraries, to allow users to more easily browse collections, thereby enhancing the usability of e-book readers.
