During the past 10 years, serious game industry has been growing steadily. But the system which could stably and reliably provide metadata information and quality information related to serious game remained unexploited. Existing systems only support the basic management functions of metadata search centered. Therefore, we have developed an integrated system to manage the quality information of serious game as well as to improve the inconvenient details of the existing systems. And we designed quality evaluation elements and quality information supply-methods, and linked up them to the system. Furthermore, we conducted user's satisfaction assessment survey on the use of the system. The advantage of the system is that the system provide a lot of useful information for general users and developers, and support a tool to manage all information related to serious game by easy and convenient method for managers.

This study was developed as a mobile serious game app (Roly Poly 160 App) based on a prototype model and then used in a public health center for diabetes patients. The mobile serious game application upgraded the mobile version of Roly Poly 160, which is a content for diabetes self-management of the existing PC version, by requesting to charge service of G city. The study period was from February 19, 2018 to May 11, 2018, and users were allowed to access the Roly Poly 160 app at least once a day for a total of 8 to 12 weeks after the preliminary investigation. As a result, HbA1C was significantly decreased(p=0.04), and diabetic knowledge was significantly higher than that before the follow-up(p=0.01). After applying Roly Poly 160 App, Satisfaction score was 3.74 out of 5 points

During wireless network operations, adaptive power control is an effective way to enhance the network performance. In this paper, a new online power control scheme is proposed based on the evolutionary game theory. To converge a desirable network equilibrium, the proposed scheme adaptively adjusts a transmit power level in a distributed online manner. With a simulation study, we demonstrate that the proposed scheme improves network performance under widely diverse network environments.

The current study explores a possible mechanism through which game users' integrated sociopsychological factors lead to a higher level of life satisfaction, based on desire-fulfillment theory as well as hedonic and eudaimonic approaches to happiness. Using data from a survey of 789 game users in South Korea, we tested the relationships of psychological variables (self-esteem and game and life-efficacy), social variables (bonding and bridging social capital), and demographic variables (age and gender) with life satisfaction. Results show that self-esteem and game efficacy were an important antecedent to the degree of users' life satisfaction. Both bonding and bridging social capital increased life satisfaction. The importance of perspectives as well as their implications for game users and further associated research is explored.

I Previous scrolling-shooter games cannot represent various emotions of characters as a personality and situations, so it can only represent simple and momentary emotions. This paper purpose to develop and applying an artificial emotion which gives emotional responses and actions to character as a personality and situations of a character. So we proposed an artificial emotion that receives emotional stimulus, analyzes what emotion will be generated, controls various emotions by a personality and time, and exports a current emotion. To visualize and to test an artificial emotion, We made a scrolling shooter game which has two characters who have a different personality each other. And we applied an artificial emotion to that game, modified it to be able to change status as emotions. To estimate a satisfaction of a artificial emotion for a scrolling-shooter game, we made up a question to two groups-one has people who likes a scrolling shooter game, the other has people who doesn't.

본 연구는 메타버스 플랫폼에서 사용자 간의 커뮤니티 사회성을 형성해 가는 과정에서 성격의 5요인이 미치는 영향에 대하여 살펴보고 상호 간에 유의미한 특성을 살펴보고자 한다. 성격 5요인의 특성으로는 신경성, 외향성, 우호성, 성실성, 개방성의 다섯 가지 요소가 있으며 이는 메타버스 가상공간에서 사용자 간의 통합 및 경쟁, 게임과 같은 시스템을 통하여 사회 형성에 많은 영향을 미칠 것이다. 성격 5요인과 반대적 성격 5요인은 메타버스 사용에서 개인의 성격을 강화하거나 약화시킬 수 있고 사용시간, 참여율, 만족도 면에서도 다른 결과를 보여줄 것이다. 소통을 중요시하는 메타버스에서 사용자의 성격에 따른 섬세한 콘텐츠 제시는 분명 더 나은 콘텐츠로 시장에 경쟁력이 있을 것이다. 본 논문에서는 메타버스의 사용이 개인의 성격에 미치는 영향을 이해하는 데 도움이 될 것이며, 메타버스 내에서 사용자 성격 5요인 성향을 정립하고 이를 통해 차세대 플랫폼 구축 및 개발에 도움이 되고자 한다.

This study proposes smart-phone game applications success model based on mobile internet success model and investigates the effects of cultural propensities especially, uncertainty avoidance and power distance at the individual level. To achieve our research purposes, the study conducted survey in Korea and a total of 221 people participated in the survey. We classified user types by cultural difference as a moderating variable. User's cultural propensity classified two groups: high uncertainty avoidance and high power distance, low uncertainty avoidance and low power distance. This study results reveal that the impact of quality factors on user satisfaction have difference according to cultural propensities.
