The problem of missing child is a social problem. It became a social problem that all parents must consider. These social and public sector issues need urgent improvement. There are many studies on the problem of preventing missing child worldwide as an area of increasing interest. However, in the past, mainly the method of monitoring the position information of the child depending on the equipment was mainly tried. In addition to this method, a method of learning local information is required. In this paper, we propose the game "Save the village," a flight shooting game based on the player's location information and local information. It is expected that it will be possible to learn local information naturally through this game. It is also expected that children will be able to cope with the situation without embarrassing or confusing even in a strange area.

The purpose of this study is to explore what causes medical college students to play games they will play and use them as academic foundation material. And lay a complex foundation for game addicts. To achieve this objective, an approach was taken as a method of exploratory case study. The participants in the study were recruited by their consent at the R meeting of the College of Medicine. Data collection was collected through a one-on-one interview with FGI. The data analysis was read repeatedly and classified into semantic units to derive the essential meaning. The study produced two essential topics and seven revealed topics. It is 'my job to play games' and 'know the importance of discrimination.'According to the analysis, the game behavior played by medical students was able to quit due to the self-efficacy experienced during the course of growth. When one's expectations were met and self-strengthened, one could see that self-control was possible through self-efficacy. It suggested that measures for sound game culture and complex strategy should be explored and measures to improve self-efficacy should be explored.

The mobile game industry has become the one of the fastest growing industries with its astonishing market size. Despite its industrial importance, a few studies empirically considered actual purchasing behavior in mobile games rather than the intention to purchase. Therefore, this paper investigates the key drivers of in-app purchase by analyzing the game-log dataset provided from a mobile game company in Korea. Specifically, the effects of goal-directed, habitual and social-interacted playing behavior are analyzed on in-app purchase. Furthermore, the recursive relationship with playing and purchasing behaviorsis also considered. The result shows that all suggested factors have positive impacts on in-app purchase in the current period. In addition, the effect of previous habitual playing has a positive impact, but the effect of social-interacted playing and in-app purchase in the previous period have negative impacts on in-app purchase of the current period. These findings can improve our understanding of the impact of game playing on in-app purchase in mobile games, and provide meaningful insights for researchers and practitioners.

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.

If game images use colors improper for certain ages, the characteristics of games disappear, and the efficiency of image expression drops. thus a study in color is very important. Nevertheless, there is a lack of research on this subject. In this study, we investigated the difference of color of game images according to users. User group is divided into all users and users over 18 years old. Among the rank of games,10 each from games for all ages and games for non-teen-rated are selected, and the game-playing images are taken as snapshots to have 100 each images each, A total of 2000 images were extracted and the mean values of RGB and HSB of each game were obtained and independent sample t test was performed. The results showed that the RGB color values between the two users were significantly significant. In the future, it is expected that it will be helpful in color selection when developing psychotherapy games and emotional games using color psychology. Furthermore, we will use color image scales to express colors as adjectives, analyze colors in a variety of ways, and investigate the difference in color of game images in each country.

The current situation and problems of sensory console games was analyzed focusing on the Nintendo 'Wii.' In order to develop the limitation of contents that lean strongly towards sports and fail to offer diversity one step further into glocal cultural contents, a solution of applying 'Bollywood,' which has a main musical format, is presented. Bollywood is a unique cultural code of India which can stimulate the purchase desires of consumers with its exotic freshness in third countries, and can be used to lead sales of a new form of game culture that is familiar yet in a new format in the 1.1 billion population Indian market. The political, social and economic codes of Bollywood are examined in this study in addition to cultural contents and codes that include Bollywood to develop contents that are not foreign to their culture.

In this paper, we consider a physics-based 2D flight simulation game where users can easily control realistic flight of a vehicle equipped with two thrusters that allow vertical takeoff and vertical landing. The flight vehicle can be manipulated by directly controlling the thrusting force at each thruster using a pair of analog input devices such as joysticks. However, it might require too much practice to make aerobatic flying solely with this kind of control. We propose a set of fly-by-wire methods that provide easy-to-use, intuitive control of a VTVL vehicle. Based on PD controllers, the proposed methods allow users to specify the velocity or position of the vehicle directly. Furthermore, they are easy to understand and simple to implement. We expect that the proposed vehicle model and control mechanism could be used in various 2D games.

The Parrondo paradox is the counter-intuitive phenomenon: when we combine two losing games we can win the game or when we combine two winning games we can lose the game. In this paper, we assume that an investor adopts the rule of the history-dependent Parrondo game for investment in the stock market. Using the KRX (Korea Exchange) data from 2012 to 2014, we found the Parrondo paradox in the stock trading: the redistribution of profits among accounts can turn the decrease of the expected cumulative profit into the increase of the expected cumulative profit. We also found that the opposite case, namely the reverse Parrondo effect, can happen in the stock trading.

In the mobile gaming market, it is desirable for a specific content to be served on various platforms. Recently, it is a very important issue in the market for mobile games. This problem incurs extra cost, because we need to redevelop existing contents to be executed on another platforms. Moreover, the release of a new platform has spent much more effort and cost developing many contents in short period of time. Therefore, we need to research about translation techniques that enable the existing contents to run on a different platform. In this paper, we propose translation techniques for mobile games. The techniques can be applied on converting mobile contents to runnable contents on a new platform. To realize it, we design and implement a source-level contents translator which is targeting Android platform using the suggested techniques. Our source-level contents translator is implemented systematically by applying compiler theory. Also, we solve partially translation problems between different programming languages. The translator has been implemented separately divided into three tasks such as kernel porting, library mapping as well as language translation. We expect these techniques to increase utilization of existing mobile games and contribute to vitalizations of mobile contents industry.
