Objective : Recently many kinds of food therapies have sprung up to prevent or manage disease and to promote health. Seeing Korean history, the Korean medical doctors have been applying food therapy based on the thought that the dietary sources were as important as the medicine. Therefore, in this study, we designed a mobile edutainment game prototype with the goal of providing education about healthy food knowledge for users who belongs to different constitutional types. Materials and Method : We adopted the Sasang Constitutional Medicine as the medical background knowledge for our edutainment game design. Based on the user study, we developed the process of edutainment system which is composed of 'My game', 'My constitution', and 'My food'. Among the whole process, we developed a prototype for the core module - the 'My game' part. This prototype used a jumping game for mobile devices that is composed of training, level 1 and level 2 stages. Results : From the target user evaluation, it was proved that 1) in terms of the learning effect of healthy diet, the edutainment game we developed has a significant advantage over the conventional learning media. 2) after playing the edutainment game, the good and bad food identification accuracy based on picture and text format were increased by 44% and 42% respectively, and 3) target users perceived enjoyment while using this prototype, as well as showed positive intention to use this game as edutainment tool in the future. Conclusion : We designed and developed mobile edutainment game prototype to educate healthy food knowledge based on Sasang Constitutional Medicine. Through user evaluation, we proved that our prototype enhanced healthy food knowledge and that user accepted the prototype as a beneficial edutainment tool.

Online game industry is also making much efforts in developing games that have emotional disposition which is rapidly growing by the increase of emotional demand by the user. In the online game development that induces immersion stimulating the emotion of the human has the evaluation stage it must surely pass, and in this stage, emotional evaluation system is known as the evaluation method that one can verify the function, usage and human emotion desire of the game before its launching. Nevertheless, at this situation the studying result is absent in the verification of efficiency and validity of the emotional evaluation system, this study is to work on the availability and validity of the emotional evaluation system as the evaluation tool of the game comparing with the Jakob Nielsen's evaluation system through common user group which are the subjects.

The 4-DAT is a tool for analyzing general development process such as XP and Scrum. In this paper, we suggest a new evaluation method based on 3-DAT for mobile game. Since the 4-DAT has inappropriate evaluation items and unnecessary elements for mobile game development, a revised evaluation method which was optimized using three dimension. The 3-D based evaluation method have development context variables of 5 items and 20 detailed criteria. They were defined based on the theory of P.Abrahammsson, B. Boehm and R. Turner. For the experiment, We applied to five mobile game developments which were earned out for 4 months. It analyzed the three factors of the development teams dependence, inequity and flexibility. This study found that short-term mobile game developments can be completed with low risk when dependence is low, inequity is high and flexibility is high.

To enhance the effect of learning in vocabulary learning, it is important first of all for learner to take active learning and be interested in learning, not cramming education. Due to this background, the instructor sometimes takes advantage of the game concepts in producing the courseware for vocabulary learning. But because of overwhelming overload in making the game-based courseware, it have been not made practical application to vocabulary learning. In this research, we study on the strategy for making practical application of the game concept to producing the courseware for vocabulary learning. And, based on the strategy, we design and implement the authoring tool of courseware for vocabulary learning based on crossword puzzle game. This tool enables instructor to produce the courseware based on crossword puzzle game easily and quickly and to make efficiently the courseware for vocabulary learning with level.

In this paper, we suggest a game system that can support network modules for multi-platform based video games, and built a system that can convert from a single-user game to multi-user game. In this system, we bring in an initial delay buffering scheme on clients to handle any periods of latency occurring from the load fluctuation in a network, when a real-time game is played, and shows that stable play for a game is achieved as the result of the scheme. This paper also presents a retransmission algorithm based on the history of game commands to handle drawbacks of UDP mechanism. And, we evaluate the network delay and packet loss using the simulation tool NS2, and shows the case of 0.3 second buffer delay is the most suitable for recovery.

Game theory has been regarded as a useful theoretical tool for modeling the interactions between distinct entities and thus it has been harnessed in various research field. In particular, research attention has been shown to how to apply game theory to modeling the interactions between malign and benign entities in the field of wireless networks. Although various game theoretic modeling work have been proposed in the field of wireless networks, our proposed work is disparate to the existing work in the sense that we focus on mobile malign node detection problem in static wireless sensor networks. More specifically, we propose a Bayesian game theoretic modeling for mobile malign node detection problem in static wireless sensor networks. In our modeling, we formulate a two-player static Bayesian game with imperfect information such that player 1 is aware of the type of player 2, but player 2 is not aware of the type of player 1. We use four strategies in our static Bayesian game. We obtain Bayesian Nash Equilibria with pure strategies under certain conditions.

In this paper, we suggested a method for game operation tools by Ultrasonic sensor. Various ideas are necessary for the development that a game is industrial. I use a Ultrasonic sensor in this study and use a model case, and an operation is going to hold a case shooting play. Therefore, I showed a former circuit and a formula related to this.

현재 게임을 제작할 수 있는 다양한 Tool들이 존재한다. 하지만 제한된 Tool을 이용하여 제작된 게임은 프로그래밍 언어로 제작된 게임과 비교 시 다양한 방법의 구현 및 게임의 퀄리티 향상에 어려움이 있다. 따라서 본 문에서는 프로그래밍 언어 중 JAVA Library를 이용한 게임을 제작하여 그 필요성에 대하여 서술하였다.

Internal organs are in a game paduk[go] to play on a printing, and a poker, Korean playing cards having cards we. And I am with all kinds of electronic amusements to do a computer with a partner and baseball, soccer, golf, tennis, several hundred to enjoy in a stadium. Most games except a computer game are local, and a case to receive a courtship is in a game during this because I need time, personnel (the other party)? and a game tool. But a computer game is single, and a game is possible, and a number for the merit that can easily play a game by an offer of all tools is, and for this reason a lot of games to enjoy in a computer please be, and it has been transplanted. I do I in order to announce that interface of a game studied a problem and an improvement plan to have let there be a few I (to game interface) if a game is ported with a computer in this study by this.

In the field of mobile games, social network games are steadily increasing in market scale and public interest every year. This paper proposes a method to design a social network game, which is one of the most successful genres in mobile games. The method uses Unity3D, the most commonly used engine for mobile game development. NGUI, a versatile developmental tool of Unity3D, is used to create shops and battle UIs. This paper particularly focuses on how to use the web hosting service to search and operate the necessary data from the database in the server. In addition, the proposed social network game is easy to implement real-time battle using Animator and Raycast, and is characterized by efficient battle implementation through time delay using Coroutine function.
