We present an estimation model for optimal channel capacity required to data traffic transmission. The optimal channel capacity should be calculated in order to satisfy the permitted transmission delay of each wireless data services. Considering the discrete-time operation of digital communication systems and batch arrival of packet-switched traffic for various wireless services, $Geo^x$/G/1 non-preemptive priority queueing model is analyzed. Based on the heuristic interpretation of the mean waiting time, the mean waiting times of various data packets which have the service priority. Using the mean waiting times of service classes, we propose the procedure of determining the optimal channel capacity to satisfy the quality of service requirement of the mean delay of wireless services. We look forward to applying our results to improvement in wireless data services and economic operation of the network facilities.

Digital items, considered as virtual assets, include avatars, accessories for the avatars, digital wallpapers, and game items, etc. The objective of this study is to examine the factors influencing the purchase of digital items. Factors, based upon Uses and Gratifications theory, including image making, self-expression, social awareness and fun-seeking, are introduced as salient variables for purchasing digital items. In addition, social identification and flow are also considered as key motivators. Statistical results indicates that social identification affects both flows and the intension to purchase digital items, and then flow next influences intension to purchase. It was also found that motives based upon Uses and Gratifications theory influences social identification, but have no impact on flow. As a conclusion, the academic and practical implications of these findings are also discussed.

For analyzing shallow-water flows over the uneven bottom, the HLLL scheme and the divergence form for bed slope source term (DFB) technique, respectively were applied to the flux gradient and the bottom gradient source terms in a finite-volume model for the shallow water equations. And also the model incorporated the volume/free-surface relationship (VFR) to consider the partially submerged cells (PSC). It was identified that a simpler version of the weighted surface-depth gradient method in the MUSCL was equivalent to the original one in the accuracy for 1D steady flows. It was verified that the flux gradient term and the bottom gradient source term were well-balanced exactly by the VFR for the 1D PSC. The VFR for the triangular PSC settled the problem which the governing equations were not well-balanced by the DFB technique for the 2D PSC. There were good agreements in simulations and experiments for 2D dam-break flows over a triangular sill and a round bump. In addition, the partial dam-break flow was successfully simulated for flooding of roughnesses in an irregular bottom as well as a sloping one. Therefore, this model is expected to be applied to the real river with uneven topography.

The purpose of this study is to measure the satisfaction factors of user experience of 'Unlimited subscription service' among subscription services and analyze them based on economic and cultural perspectives. By recruiting the '20-'30s who had experienced using service, they attended a survey which was based on the reconstructed honeycomb model of Peter Morville. As a result of the survey, in terms of economic perspective, cost of service, and the ease of subscription inflow were the main satisfaction factors. From a cultural perspective, the familiarity with service and belief and experience of sharing content with people around them were the main satisfaction factors. Therefore, it can be inferred that the satisfaction of the user experience of the subscription service should be firstly satisfied with economic satisfaction, which leads to cultural satisfaction. This study is expected to be used as research data on user experience and satisfaction factors of unlimited subscription service.

Modern society is the era of convergence, and storytelling requires the necessity of storytelling in which two types of data types, emotional stories and information, are fused. Particularly, in the case of VR contents, the user must directly participate in the content and select the information through the process of freely searching $360^{\circ}$ space, so that the user can interact with the content immediately. Therefore, there is a limit to access to the existing storytelling method, and it is considered that the implementation of 'convergent storytelling' that meets two areas of sensitivity and information is considered to be an urgent genre. In this paper, we focus on the spatial characteristics of VR contents, and then, as a way to effectively implement 'convergent storytelling' in VR contents, We propose a custom system by organizing the type into a circle structure. Based on this, it is expected that the technology will be developed into a research of a personalized system that meets two areas of emotion and information by utilizing the context recognition process for VR content and interaction in the fourth industrial revolution era.

Travel YouTubers who cross the boundary between tradition and novelty communicate by sharing their activities with others through SNS-based media. Media content should not only satisfy individuals, nor should it be too purpose-oriented. YouTube channels should be operated so that users can easily access content naturally, and more diverse methods can be pursued based on usage patterns and satisfaction theory. This study is about the type of perception of Generation Z on travel YouTube titles. As a result of conducting QUANL program analysis on 34 Q samples and 28 P samples from the Q methodological perspective, a total of three types were found. For types with unique characteristics, the first type was named "attention of keywords that draw imagination," the second type was "preferred to stories that stimulate curiosity," and the third type was "image satisfaction reflecting expectations." In addition, considering the characteristics of each type found, the scalability and strategic plan of the activities that Generation Z travel YouTubers want to unfold were presented.

The study aims to understand undergraduates' and graduate students' perceptions and satisfaction with online learning platforms and to verify the relationship between usability factors and satisfaction with online courses. The literature review facilitated the summarization of major factors to be considered in the online learning platform development process and established the research model. The follow-up survey verified the perceptions of university constituents regarding the fulfillment of the university online learning platforms' user interface principles, platforms' usability, satisfaction with platforms, and satisfaction with online courses. Causal relationships between variables were tested and modeled by analyzing survey results. We also confirmed that the same model can be applied to different types of learners and various types of online learning methods. This study is significant in verifying that the fulfillment of the platforms' user interface design principles can affect satisfaction with online courses using the platforms based on learners' evaluation results. We expect that the research model proposed in this study can contribute to the improvement and development of online learning environments in the future.
