This study is conducted to explore the possibility of service convergence to promote mobile learning. This study has attempted to identify how mobile learning service is provided, which services among them are considered most popular, and which services are highly demanded by users. This study has also investigated the potential opportunities for service convergence of mobile service and e-learning. This research is then extended to examine the possibility of active convergence of common services in mobile services and e-learning. Important variables have been identified from related web pages of portal sites using social network analysis (SNA) and association rules. Due to the differences in number and type of variables on different web pages, SNA was used to deal with the difficulties of identifying the degree of complex connection. Association analysis has been used to identify association rules among variables. The study has revealed that most frequent services among common services of mobile services and e-learning were Games and SNS followed by Payment, Advertising, Mail, Event, Animation, Cloud, e-Book, Augmented Reality and Jobs. This study has also found that Search, News, GPS in mobile services were turned out to be very highly demanded while Simulation, Culture, Public Education were highly demanded in e-learning. In addition, It has been found that variables involving with high service convergence based on common variables of mobile and e-learning services were Games and SNS, Games and Sports, SNS and Advertising, Games and Event, SNS and e-Book, Games and Community in mobile services while Games, Animation, Counseling, e-Book, being preceding services Simulation, Speaking, Public Education, Attendance Management were turned out be highly convergent in e-learning services. Finally, this study has attempted to predict possibility of active service convergence focusing on Games, SNS, e-Book which were highly demanded common services in mobile and e-learning services. It is expected that this study can be used to suggest a strategic direction to promote mobile learning by converging mobile services and e-learning.

In the domain of IS, game was used as a tool to enhance the results of decision making, education and more. In another stream of research, researchers focused on revealing the motive of people playing games. This study focuses on the effect of the tool; increased accessibility via mobile, to online game using patterns and behaviors. Due human reaction towards competition, technology acceptance and the online game's gambling traits, it is expected that the increased mobile accessibility (tool) will increase and intensify the game playing behavior. Also, it is expected that the in-game purchase will increase as well. In depth interview with both game service providers and players is planned to confirm that the mobile version acted as a tool to increase accessibility, rather than a additional game. Survey along with an interview is to be conducted to find relevant play and spending patterns if they are to exist.

Many of users play Mobil Social Network Games (M-SNG). M-SNGs are played through social network, and typically features multiplayer and asynchronous gameplay mechanics. It is most often implemented as mobile devices with mobile instant messenger app. Kakaotalk provids mobile game platform. The purpose of this study is to find significant factors that have effects on the commitment of M-SNGs. We also conduct multi-group comparison test to study the difference in factors of models between time t and time t1. Time t is October, 2012 and time t1 is April, 2016. This study is to empirically test the research model using data collected from M-SNGs' users. We survey two different groups of time t and time t1 people with the same model. We use structural equation model analysis with AMOS 18.0 and compare two models of different times. This study is to give academicians and practitioners insight about its effects and implications

This essay analyzes space in augmented reality games, and attempts to offer space analytic standards of mobile augmented reality games in regards to space in existing games. This article proposes categorizing criteria based on the following factors: Analysis of space in existing games, Jason Jerald's Three Virtual Space Horizon Categories, interaction between virtual world and real world, and Lavroff's Three deciding factors of reality perception in virtual reality. It is meaningful that the analysis criteria of the Augmented Reality game space is presented through this analysis.

Recently, local game companies have been increasingly producing PC-based game that were popular with users among the existing commercialized games into mobile games through remakes. In this paper, we studied how console-based game influenced mobile augmented reality game . Through this process, we extracted five characteristics of mobile augmented reality, then interpreted and classified the meaning of this. Based on released in 2016, the scope of research is limited to console and mobile games previously released. According to the analysis, showed 50 characteristics and borrowed 78% from its existing Pokemon, 22% from its new production, and contained 24% reality. We also found that the Pokemon game series , and the exotic series had much influence on production. Based on this research data, we hope that augmented reality games for mobile will be made more active using existing game contents. It is also hope that such activities will lead to the growth of the home and abroad game industry.

From the era of feature phone to the current smart phone which bloomed Social Network Games(SNGs), mobile games have held the top position as killer contents of mobile market. Mobile game has many constraints such as specification of device, network status, and external environment. Based on common perspective of game research, these factors have negative influences on flow of user. Even with these opinions, most mobile gamers have felt satisfaction. To explain this phenomenon, our research focuses on the constraints. Referring to theoretical concepts, we attempt to clarify the relationship between game features and flow through survey methodology. Our finding shows that the constraints have a positive effect on flow even though it disaccords with previous studies. Therefore, we argue that users of mobile game have sense of satisfaction not a cognitive overload as discomforts.

This paper presents a real-time fire simulation on the mobile phone using stable fluid animation techniques. Stable and fast fluid simulation methods are developed in PC and console games, but fluid simulation and interactive fluid models require too much system resources for applying on mobile environment. We studied and implemented physics-based models for fluids like fire and smoke effects using billboard and stable fluids simulation method on mobile 3D system. The mobile platform of our system is WIPI, which is the standard mobile platform in Korea, also we adopted NF3D API for our 3D programming API. We implemented real-time fire simulation and added it in mobile 3D game, "Rupee Story".

The big issue according to the advance of wireless internet is the design of on-line game under mobile computing environment. The current mobile games have constraints in implementation of on-line game due to the low performance processor. small memory size and short battery time. Therefore, nowadays one-button games which are simple and easy to manipulate, have attracted great interests. In this paper, we designed and implemented the trandition Jeki-chaki game, which is a kind of one-line game, using a mobile handset.

During the COVID-19 pandemic, games played an important role in people's lives. Numerous online users flocked to the game platform, and brand companies started using online games to promote their products. Medical institutions have also implemented policies for healthy physical activity through online games. In order to attract more global game users, research on immersion in games is also very important to prevent users from leaving the platform. Therefore, it is necessary to analyze the common immersion elements of popular games by country and study them from the perspective of changing devices. In this paper, representative popular games of Korea, China, and Japan, which are recently called the dark horse of the game industry, are classified by devices of mobile, online PCs, and VR games and analyzed using immersion analysis tools proposed by researcher. Next, the representative metaverse games of the Web 3.0 era were analyzed, and their characteristics were compared with the results of the immersion analysis between Korea, China, and Japan, and proposed as game immersion elements suitable for metabus games.
