The recent growth of smartphone users and high speed network has fueled the expansion of the market for mobile application. Among these applications with various purposes, smartphone games are the hottest contents on this market. Smartphone games are far different from former games due to their new input and output interface (e.g. touch sensors and gyro sensors).It is possible that the most resonable way to categorize these new smartphone games is comparisons of different objects, in this case, various smarphone games. But there exists no classification of the games neither for the use of the market nor the purpose of researches. Even though there are few classifications for games, those classifications have a major flaw that their criteria are derived from superficial features of games. In this paper, we propose a new method to categorize smartphone games through game mechanics of principal design components.

As smartphones have become widely used, topics of smartphone become a hot research subject in IT technologies. Many applications have been developed for the smartphone and the application market has become more and more increasing. However here are few studies or application developments on Korea's traditional games. In this paper we developed Korea's traditional board game Gonu. People who are young or old can play the game. We expect that many applications which related with Korean culture are developed on the smartphone environment.

Smartphone game market, smart phone appeared on the market and soon developed rapidly, generation change is happening. Generally, Smartphone games are only short-lived super cell's Clash of Clans is gaining popularity for over two years. So Clash of Clans this game with hold most characteristic elements of the defense and plunder on the subject analyzed the fun factor. In order to analyze the defense and plunder elements were prepared Clash of Clans and Kings of Thieves in cases. Two of the cases, depending on the fun theory Preparation, A sense of space, A solid core machanic, A range of challenge, A range of abilities required to solve the encounter and Skill required in using the abilities were evaluated in the fun factor analysis of defense and plunder elements.

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.

게임에서 플레이어에게 시각적으로 제공되는 환경을 View라고 하는데, View의 전환만으로도 전혀 다른 게임의 경험이 가능하다. 본 논문에서는 car racing game에서 View의 전환에 따른 게임의 경험 차이를 비교하였다. 우리는 ARcore 라이브러리를 사용하여 AR car racing game을 구현하였고 virtual joystick을 사용한 Interaction 방법을 구현하였다. Top down view와 first person view의 차이점이 플레이어의 실감에 어떠한 영향을 미치는지 연구하기 위해 두 view을 구현하여 pilot study를 수행하였다.

In this paper, we devise a Shapley-value-based covert channel in smartphones. More specifically, unlike ordinary use of Shapley value in cooperative game, we make use of a series of Shapley values, which are computed from sensor data collected from smartphones, in order to create a covert channel between encoding smartphone and decoding smartphone. To the best of our knowledge, we are the first to contrive covert channel based on Shapley values. We evaluate the encoding process of our proposed covert channel through simulation and present our evaluation results.

This study explored Korean college students' smartphone game behavior for the pastime. Smartphone games have weakness that is not appropriate for playing the game because of small screen and non-sophisticated interface for operation. To defeat the disadvantage, the games employed minimalism like conciseness or simplicity. The study explored how conciseness influences perceived ease of use, perceived enjoyment, flow, and intent to use the game through PLS path modeling. We found that every hypothesis except a path, perceived ease of use to flow, proved significant. This result means that smartphone game design should consider the interface of users' convenience and user experience practically. Finally, based on the findings, suggestions for future studies were discussed.

The purpose of this study was to investigate effects of 12-week physical activity intervention on obesity and metabolic syndrome risk factors and smartphone game time in children. A total of 27 children(fifth grade elementary school students) participated in this study. The subjects were divided to exercise group(n=16) and control group(n=11), and participants in exercise group performed running and jump rope(60min/day; 3days/week; 50~70% of THR) during 12-week. We analyzed measurement data using two-way ANOVA. As results, obesity indices except body weight and metabolic syndrome risk factor decreased significantly in exercise group compare with control group. And VO2max increased and smartphone game time decreased significantly in exercise group compare with control group. In conclusion, we suggest that 12-week exercise intervention in children has positive effects on obesity and metabolic syndrome and improve negative lifestyle such as smartphone game.
