A moving picture in online game is one of major ways to advertise online games, which gives a lot of help in playing game. In this case, a moving picture is compressed to variable bit rate for efficient storage use and network resource efficiency. Adaptable bandwidth allocation technique builds a transmission plan of a game moving picture. And, then some frames are discarded when transmission rate by the transmission plan is larger than available transmission rate, until transmission rate satisfies available transmission rate. Thus, performance evaluation factors in adaptable bandwidth allocation technique may be dependent on discarding order of a frame which transmission rate is much influenced. In this paper, in order to show the performance, a CBA algorithm, an MCBA algorithm, an MVBA algorithm, [6] and [7] algorithm were applied to a transmission plan in the adaptable band width allocation technique using various frame discard methods and performance evaluation factors were compared in among smoothing algorithms.

UI design is growing in meaning and form itself through the development of hardware and contents. And it makes users accept its interface as a extension of the body and mind because of the substantial rapport of the user and contents with developing of device and graphic. In this study, we analyzed user interface in a view of digital storytelling by observing of its role within user and contents. Not only this, classifying and investigating story elements in the games for forming the theoretical basis of storytelling UI are enforced. For the case study of UI, we choose the game, Diablo, Half-Life, and Homeworld because the game is suitable for the application of node-type storytelling and effectively uses graphic and input unit. This analysis explains the interface has the contents data that divided or shared and it means the interface performs its part of story nodes, which are extracted from the story, and choice. And we analogized that the story elemental can be substituted and used practically for interface because the stories made through the thing that users and developers are in the space of coexistence by the interface. Storytelling UI will be a good way to make a most intriguing piece as a joyful spontaneous complex that use story node. It is worth by reason of making by user and discovering live inner story so that it can approach to the substance of the story.

This study is an interaction design study which can improve the usability of random item boxes that are used as in - game contents in Korean mobile games. Currently, Korean mobile game sales continue to rise. Sales of random item boxes are the main reason for the increase in sales. Problems with the use of random item boxes have been continuously raised, and legal regulations are currently in place. When using random item boxes, the user can not know the exact percentage information. There is a concern that this expresses gambling. In this context, we have studied interaction design to improve the usability of random item boxes, and conducted user online surveys and in - depth interviews to provide users with a better game experience. As a result, it is shown that providing percentage information intuitively when using random item boxes can enhance user experience. Through this study, it is expected that interaction design research will be actively conducted to provide a better user experience when using random item boxes.

Education tools expressed in texts and images turned into the edutainment such as a education and playing experience. Augmented reality(AR) technology in the field of edutainment was possible to have an amused-education by maximizing experiences. Recently, it is also served in a variety of mobile applications which exploit AR technology. The paper is to describe on the practical measures for the experience of education through designing and implementing edutainment contents. The implementation makes use of a engine 'Vuforia', and a platform 'Unity 3D'.

Following rapid development of software and hardware technologies and increasing enhancement in arithmetic capability, there are more and more content that can be accommodated and processed in video games, which is also increasingly complex and fine. Cutscene as a main narrative method have been developed, which have become necessary to express some key plots and important scenarios in games. Good cutscene can strengthen engagement of players with virtual world in games and make players share affection and sorrow with roles in games; while badly-designed cut-scene or overused cut-scene will impair immersion of players and affect players' gaming experience; for this reason, developers should not continue cut-scene design just from opinions of designers nor make players passive receivers, instead, they should reduce as much as possible interruption by cut-scene to players' immersion and grant players with better immersion. After all, only designs depending on demands and preferences of players by having some knowledge of impacts of cut-scene on players' immersion can be accepted by players.

This study proposes an OMS/MP preparation methodology using a simulation method instead of a survey method. We applied our methodology to the next generation detection radar, providing reasonable peace- and war-time OMS/MP values. Based on these results, we propose the process to calculate RAM objective values. The previous survey method required to supplement its method since the method used data from a similar weapon system. In addition, the previous method didn't provide enough reliability for the future weapon system. Instead of using the previous survey method, we propose to use war game simulation, which provides a better OMS/MP values. Based on these results, we propose the logical consecutive process that prepares combat and simulation scenarios, peace- and war-time OMS/MP values and RAM objective values.

Despite the increasing adoption of gamification and its huge potential in tourism, research in gamification is still limited. As preliminary findings show that the effectiveness of gamification depends on the context of its application and the players' use of the gamified app, this paper fills in these gaps: by exploring and analysing the application of gamification in a specific e-commerce tourism context; and assessing the gamification's effectiveness by measuring the players' gamification usage and the latter's behavioural and psychological outcomes. The gamified TripAdvisor website and its Facebook enabled gamification app are used as the specific context of the study. Findings from a survey conducted on TripAdvisor users provide useful practical and theoretical implications to gamification designers and researchers alike on how game mechanics can be designed for enhancing the users' motivation, flow, task involvement and engagement with the 'play' tasks, and so, increasing the gamification's effectiveness.

In CCTV environments, a lot of learning image data is required to monitor illegal dumping of garbage with a typical image-based object detection using deep learning method. In this paper, we propose a system to monitor unauthorized dumping of garbage by learning the articular points of the person using only a small number of images without immediate use of the image for deep learning. In experiment, the proposed system showed 74.97% of garbage dumping detection performance with only a relatively small amount of image data in CCTV environments.

대학의 게임개발 프로젝트에서 게임QA를 수행할 때 일정한 가이드라인이 없이 진행되는 경우가 많다. 게임QA 중 소프트웨어 테스팅 부분은 최근 확정된 ISO/IEC/IEEE 29119 표준을 기준으로 할 수 있을 것이다. 다만 29119 표준의 내용이 매우 구체적이므로 이를 대학의 학기라는 제약에 맞춰서 진행하기 위해서는 표준이 제시하는 프로세스에 대한 최적화 과정이 필요하다. 본 논문에서는 ISO/IEC/IEEE 29119 표준을 간략하게 살펴보고 이중 테스트 계획 수립 프로세스를 어떻게 최적화할 수 있는지 방안을 제시하였다.

IoT technology application has been part of modern people's everyday life. This technology makes people to depend on smart devices. 'Smartphone' is the most typical example. Despite the advantages given by this device, the bad side effects are also notable. This paper presents interactive content on the dependence of smartphone device. The research objective is to make individuals to reduce the use of smartphones by realizing their own problems of smartphone dependency. Research was progressed by analyzing aspects obtained from users participating in the self-developed interactive game contents. As a result of the analysis, approximately 68% of people were aware of the problem through this content. This indicates the potential of using convergence research in interactive contents with other fields furthermore.
