Game have become a universal leisure culture for the world. However, not only did the development of the game industry have a positive impact on society, but it also brought about various social problems, such as adversely affecting youth and encouraging criminal acts. In order to minimize these effects, countries around the world operate a game rating system to provide games suitable for age and social values from children and young people to the general public. Since games are new digital content, the limitations of the rating system are still discussed in many studies. Therefore, this study investigates the current status of global game regulation by investigating game rating systems of various countries including Korea. In addition, by comparing and analyzing the game rating system in Korea and the system of other countries, this study suggests a direction to improve our system more appropriately. The results of this study will contribute to securing the effectiveness and standardization of domestic game classification system.

As the flourish of today's supply chain, the traditional model of replenishment will cause accumulation of excessive inventory to the retailers and customers, or cause shortages and inability to meet the demands. To solve this problem, Theory of Constraints (TOC) proposed the replenishment model of demand-pull, combined with the establishment of factory-ware-house to achieve performance improvement. In the absence of empirical research, this study applied the Bean Game developed by Dr. Goldratt to design a supply chain system for different scenarios, in order to allow players and managers better understanding and supporting the TOC replenishment method through the operations of the game.

Various tools and studies improving quality of gamification systems have been suggested. Among those tools and studies, Butler suggested the gamification framework, which shows the preference of different game mechanics, applying particular motivational and behavioral tendencies in the Myers-Briggs Type Indicator(MBTI). The purpose of this paper is to validate if the preference of different game mechanics by MBTI personality types proposed by Butler would be existing. This study pointed out the problem of suggested gamification framework from butler through literature survey. Also, this study conducted statistical analyzation and survey to prove correlation between MBTI personality types and game mechanics. Through an experiment and analysis, this study proved that there is no correlation between MBTI personality types and preference of different game mechanics. The designer of gamification systems should consider that it is not effective to apply differential game mechanics by MBTI personality types. If need to design a gamification system, designer must consider game mechanics's characteristics in applied environmental condition.

We propose a heuristic algorithm for war-game model that is appropriate for warfare in which the maneuver of the attacker is relatively certain. Our model is based on a multi-weapon extention of the Lanchester's square law. However, instead of dealing with the differential equations, we use a multi-period linear approximation which not only facilitates a solution method but also reflects discrete natures of warfare. Then our game model turns out to be a continuous game known to have an ${\varepsilon}$-Nash equilibrium for all ${\varepsilon}{\geq}0$. Therefore, our model approximates an optimal warfare strategies for both players as well as an efficient reinforcement of area defense system that guarantees a peaceful equilibrium. Finally, we report the performance of a practical best-response type heuristic for finding an ${\varepsilon}$-Nash equilibrium for a real-scale problem.

Character customization means a series of processes to build a characters. Mobile character customizing system is very scarce than Online RPG system qualitatively or quantitatively. In this paper, I will propose some effective elements about A DIY character system that must be suitable for the mobile environment system. The reasons why Select System is mainly used as the customizing system in RPG are as follows; First, the screen of a mobile device is small; Second, it is due to the space-time characteristics with which mobile games are played. In the middle of playing a game, a customizing system should be adopted in order for players not to feel bored. In addition, avatar's costumes should be continually updated.

Interest in Augmented Reality (AR) game $Pok{\acute{e}}mon$ GO is getting heightened. However, based on its characteristic, various direct and indirect problems are highlighted, thus increasing concerns. Although the game is not formally released domestically, there are limits in national game classification to apply on such outdoor Augmented Reality game. This paper will examine the problematic cases regarding Pokemon GO and analyze internal and external game classification system to discuss safe gaming measures for domestic users. In result of examining cases, need for adding 'physical danger' in current game classification system for user's safety was shown. As the government's game regulation is being eased, appearance of a variety of games using Augmented Reality technology in near future is predicable. Therefore it is important to prepare improvement of game classification system as a pre-safety measure, and it is expected to bring positive effect on game usage and industrial growth through safe game usage.

Last decade, IT industry in Korea has been developed greatly. The game industry as an international leader has given good value added to its country. Game industry is one of the speedy improved one and it showed over 20% of growth rate from 2002. Most distressings in Game industry, there are no established costing system in spite that there should be in emerging market. In 2004, Game Contents Costing Model using Mission and Event was developed and also the study of Game Elements weight was done in 2005. The cost of Game Contents can be calculated by GEP and its unit price. The study of Game Contents Sizing Model was done in 2005. The costing of Game Contents by single Game Element which represents software which is one of 3 Game Elements-plan, graphic and software-and it is counted by mission and event. If the software element only can not well represent Game Contents volume, we can include plan and graphic elements for Game Contents costing. And we can say above two methods as a costing model of Game Contents. In this paper, these models were tested empirically and proved as usable.

It is very difficult, but important, to induce and maintain voluntary user engagement in content. For example, many Internet contents provide financial rewards for the user's participation and maintenance. However, there are limitations to methods such as stimulating only external motivations, such as monetary rewards, and sophisticated design and management are needed to obtain sustained and voluntary user participation in content. For this purpose, we propose a Gamified CMS that extends the existing Content Management System (CMS) by referring to the example of the Gamified Learning Management System. This will ultimately increase the participation and commitment of users in content.

In this paper we propose a method to analyze user's motion as a game command, and implement a sports serious game applied the motion analysis method as a command interpreter. Recently, various contents platforms appear in industrial market, the computer game contents plays an important role in these emerging platforms as a killer contents. The computer game has enough values as an independent major cultural product, moreover it has the potential to be applied in various other fields such as education, healthcare, training, and so on. It could motivate users to do something continuously, and it could also support an immersive environment in a certain special game contents such as VR game. The Serious game 'ChoDeungGangHo', implemented in this paper, is the sensory healthcare serious game based on 3D run game and fitness game. It is designed for user to train the various exercise element by just playing the game, and it also supports the user management system and the linkage of social media. We proposes the sensory serious game 'ChoDeungGangHo' as a model of commercial serious game.
