This study looks at the social implications of gaming disorder by considering the situation in Korea. Focusing on specificity of game genres, this study analyzed two aspects of the game playing effect-positive(cognitive needs) and negative(game addiction)-and suggested directions for game regulation policies and game addiction studies, since game playing effects are closely related to game regulatory policy. To analyze game effects and attitudes to regulations, this study performed regression analysis based on the online survey. Results show that game playing effects and attitudes toward game regulation differ based on the nature of game genres. While longer gaming increased the effect of addiction, it also increased cognitive needs. Playing roleplaying, Aeon of Strife, and strategy game genres(RAS), which are subject to game regulation, increased game addiction levels but simultaneously contributed to increased cognitive needs. While playing augmented reality genres positively affected cognitive needs, it also showed favorable attitudes to general game regulation.

Objectives : The objective of this study is to examine the experiences of Internet game experience targeting to University students in Korea. Research topics was "What is meaning of internet game to the University students?" Methods : Classical phenomenology underpinned this study. Seven qualitative studies of University students were conducted between 20 and 23 years old. Semi-structured interviews were conducted. Interviews were audio recorded and transcribed verbatim. Phenomenological thematic analysis of data was undertaken. Results : The findings pivot around three interconnected themes :[Expectations for the emotional needs], [Spend time in the cyberspace], [Relieve stress throughout the game], [Instead of satisfaction from virtual reality], [Internet gaming repeat and desires]. The basic need for getting into internet game was [satisfaction from virtual reality was identified]. While internet games was eliminated stress, [Expectations for the emotional needs] and [Spend time in the cyberspace] were the catalyst that makes them repeatedly getting into Internet the game. Based on the result, I suggest that Internet gaming should be recognized as a tool to relieve stress for college students, But it is not satisfied with the reality in virtual space. Therefore, the strategy must be to recognize reality accompanying. And Using a lot of time in cyberspace make them cause of internet game addiction. Therefore, it requires a systematic strategy for the Internet using time limits. Also the emotional needs met were motivated to repeat an Internet game. So another way to meet the emotional needs to college students should be sought.

The purpose of this paper is to make a game design to overcome traditional prevention system. Cases such as recent cockroach floodings in Seoul, which shows difficulties on understanding the appearance pattern of cockroaches and limitations of the quarantine systems are increasing frequently theses days. In particular public sewer systems which is essential for urban development, face problems due to urban sprawl. In order to solve the problem this study proposes a game design building collective intelligence through citizen participation on cockroach prevention problems.

The progress in Information & Communication Technology enables data scientists to analyze big data for identifying peoples' daily lives and tacit preferences. A variety of industries already aware the potential usefulness of analyzing big data. However limited use of big data has been performed in game industry. In this research, we adopt data mining technique to analyze data gathered from a strategic simulation game. Decision Tree, Random Forest, Multi-class SVM, and Linear Regression techniques are used to find the most important variables to users' game levels. We provide practical guides for game design and usability based on the analyzed results.

This study examines the game balance of the MOBA game genre, which was selected as a model item for the Asian Games. The "bird-eye view" was used for a more efficient representation of 3D modeling. Based on that, statistical analysis was conducted to present appropriate game camera settings and camera balance to match the competitive structure of the MOBA game. A review of the game camera settings reveals that 64° to 70° is the angle that minimizes the difference in vision between the two-player teams the most. Through a one-way ANOVA analysis, we found that the user ranking level and SVB value are closely related. Therefore, the factor of the regression equation using the SVB value must have a user ranking level. As a result of the optimized camera focus analysis of , the camera setting methods were classified into 3 types. For main action games, the recommended camera angle is 64°~66°, and the recommended camera focus is 11.2 mm~19.3 mm. For action and strategy games, the camera angle is 66°~68°, camera focus - 19.3 mm~27.3 mm. And lastly, for the main strategy game, the recommended camera angle is 68°~70°, and the camera focus is 27.3 mm~35.3 mm.

This study approaches how newly emerged game companies has implemented strategies for product diversification according to market growth cycle(beginninggrowing-mature) by empirical case study through evolutionary theory and resource based theory approach. At the beginning, online game companies had grown with different strategies(technology based, service based) by initial condition(genre, technological level, user attribute). After market growth, for product diversification, these companies carried out path-dependent alliance strategy(complementary, competitive) depending on resource base(technology capacity, service capacity based). As online game market getting mature, these companies has adapted flexibly in responding to market growth cycle by integrated strategy(naturally selected to mobilize every possible resource capability). By analyzing the alliance strategies pattern of online game companies in newly emerged game industry according to market growth cycle through combination of resource based theory and evolutionary theory, these results suggest that new industrial, theoretical, policy model is required.

Online game industry has achieved remarkable development not only in Korea, but also in the world with support from huge progress in information technology. By the way, there was calm period that top tier MMORPGs had held their ranks in oligopoly situation before Aion's appearance. At that time, NHNgames succeeded to penetrate into the market and settle down as a major player. In this context, this study will identify the factors of successful market entry strategy and draw helpful ideas by analyzing case of NHNgames which succeeded to enter the market of MMORPG through the basic strategic framework of Kalyanaram and Gurumurthy. This discussion will provide several implications for the solution of online game market penetration problem which might be never ended and for the way of industry's development.

The cooperative cost sharing scheme for Dust and Sand Storm(DSS) in North East Asia, as suggested in Song and Nagaki(2007), may not be feasible due to possible defection(s) of participating countries. If non-cooperative strategies are more plausible, Nash equilibrium can suggest possible outcomes of the cost sharing game. The result from the continuous strategy model shows that there exists an infinite number of Nash equilibrium such that the summation of investment from each country is always equal to the required budget of the ADS pilot project. It is also discussed that the discrete strategy model points to only 3 Nash equilibria in continuous strategy game outcome and the cooperative game solution may be just one of the infinite equilibria.

The optimal price strategy selection of two bounded rational cognitive mobile virtual network operators (MVNOs) in a duopoly spectrum sharing market is investigated. The bounded rational operators dynamically compete to sell the leased spectrum to secondary users in order to maximize their profits. Meanwhile, the secondary users' heterogeneous preferences to rate and price are taken into consideration. The evolutionary game theory (EGT) is employed to model the dynamic price strategy selection of the MVNOs taking into account the response of the secondary users. The behavior dynamics and the evolutionary stable strategy (ESS) of the operators are derived via replicated dynamics. Furthermore, a reward and punishment mechanism is developed to optimize the performance of the operators. Numerical results show that the proposed evolutionary algorithm is convergent to the ESS, and the incentive mechanism increases the profits of the operators. It may provide some insight about the optimal price strategy selection for MVNOs in the next generation cognitive wireless networks.
