In the present study, practical measures were to be presented for prevention of smartphone game addiction and school violence by analysis of the effects aspect of the smartphone game addition by elementary school students on school violence awareness. For this purpose, a questionnaire survey was conducted for the subject of 6th graders attending an elementary school located in K city of Jeollanam-do, and a total of 258 copies were utilized as the final analysis data. Considering the analysis results, significant differences in the smartphone game addition were observed first as a function of the elementary school students' sex and game use time. The level of smartphone game addiction was observed to become higher for male students than female students, and the higher the longer the game use time during a day. Secondly, a positive (+) correlation was observed to exist between the smartphone game addiction and the school violence awareness. Thirdly, the variable affecting the school violence awareness among individual sub-variables for the smartphone game addiction was shown to be a problem with loss of control and power of reality test. The higher the addiction level of each variable, the negative tendency for school violence awareness was shown to be increased. Based on such analysis results, policy-wise, practical suggestions as well as directions for the follow-up studies have been presented for the improvement of smartphone game addiction and school violence awareness.

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.

In this paper, the prototyping process for developing syllable-initial consonant-based game 'Korean Guards' is described. Users may effectively learn Korean words using alphabetically sequential approaches, but the easiness of access bestowed on the smart environments and game algorithms could be fully utilized for the functional advantages for educational purposes. This functional game is developed on Android OS and the prototypical outcome is shown.

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.

This paper presents the development of a racing game by controlling multiple smartphones based on ad hoc communication. The proposed racing game by the smartphone-based control interface does not require any specific game console or remote controller. Thus, any multiple users who have smartphones are able to play the game in a monitor at the same time. In addition, the developed game is applicable to actual mobile robots in cases where the positions of all robots are measured, since its game unit is a mobile robot model with a differential drive. An experimental result shows that the racing game in a PC can be realized by the proposed communication interface through four iPhones based on acceleration sensors.
