MMORPG게임의 구현에 있어서 가장 큰 문제의 하나는 서버와 연결된 클라이언트들 사이의 동기화이다. 이를 위해서 MMORPG게임에서는 grid-based filtering을 적용하여 동기화 문제를 해결하고 있다. 그러나 MMORPG게임의 형태가 이인칭 관점 시점의 2D에서 일인칭 관점의 시점의 3D 게임으로 변함에 따라서 grid-based filtering으로 인한 동기화는 낭비적인 요소를 포함하게 되었다. 즉 일인칭 관점시점의 3D게임에서는 가까운 거리의 캐릭터 사이에도 주변 장애물의 영향으로 비 가시관계에 놓임에 따라서 동기화의 필요성이 없어지는 경우가 생기게 된다. 따라서 본 논문에서는 일인칭 관점 게임의 3D MMORPG게임에서 컴파일 시 각 셀을 중심으로 가시성 테스트를 수행하여 가시영역내의 셀들만을 동기화 대상으로 지정한 후 게임 진행 시 현재 셀 속의 캐릭터들에게 동기화 대상으로 설정된 셀 속의 클라이언트들만을 동기화 시켜줌으로서 통신량을 줄여주는 방법을 제안한다.

The social networking services (SNSs) have become popular among smartphone users, and one of the most popular services. In order to explain users' motivations toward SNS, this study considers uses and gratification theory which can explain individuals' motivations to select certain media channels. The purposes of this study is to investigate the relationships between motivations and addiction of SNS, and between addiction of SNS and decline in the subjective wellbeing. We examine moderating effects of social tie based on the social capital theory in the relationships between SNS addiction and decline in the subjective wellbeing. The motivations of SNS are subdivided into emotional motive (entertainment and fantasy) and cognitive motive (information share burden and challenge burden) based on the use and gratifications theory. The addiction of SNS is subdivided into time tolerance, withdrawal symptoms, interruption, and barrier of living. The data used in this study were collected from 286 SNS users through surveys. The data analysis in this study was performed using AMOS 17.0, and we used SEM(Structural Equation Modeling) methods in order to test the research model. The result shows that the emotional motive(entertainment and fantasy) and cognitive motive(information share burden and challenge burden) have an effect on the addiction of SNS. Especially emotional motive such as entertainment and users' fantasy toward SNS is an important factor that can cause SNS addiction. The addiction of SNS such as time tolerance, withdrawal symptoms, interruption, and barrier of living has an effect on the decline in the subjective wellbeing. Our result show that social tie partially moderates the relationship SNS addiction and decline in the subjective wellbeing. In addition, social tie between interruption of SNS and decline in the subjective wellbeing is an important moderating factor. The results focuses on the understanding toward relationship between SNS addiction based on the online and decline in the subjective wellbeing in the real world. The findings of this study also provides theoretical as well as practical implications which reflect the major features of SNS, and moderating effects of social tie based on the social capital.

조직간 정보시스템의 성공적 구축을 위한 전략적 관리는 자동화된 정보기술을 둘 이상의 조직이 공유하는 것이다. 정보기술의 사용은 경쟁적 우위를 제공할 뿐만 아니라 조 직간의 거래비용과 교섭력을 향상시킬 수 있다. 조직에 영향을 미치는 다양한 특성들, 즉 조직구조, 조직전략, 유휴자원의 정도 등과 같은 요소들에 의해 조직상호간의 관계는 각기 다른 형태로 구분되며, 전략적 기회 제공을 위해 조직간 정보시스템을 추구하는 기업들간에 는 다양한 형태의 개발동기요인들이 나타날 것이다. 본 연구에서는 조직상호간의 관계에 대 한 경쟁적 환경과 각 기업들이 가지고 있는 조직적 특성 요인들을 토대로 어떤 경쟁환경에 서 어떤 조직적 특성을 가진 기업이 왜 조직간 정보시스템을 개발하고자 하는지에 대한 살 펴보고자 하며 이에 대한 이론적 모형과 이들 특성들에 대한 가설을 제시하여 추후 실증분 석을 위한 토대를 마련하고자 한다.

To investigate the role of positive emotion in education, we have reviewed the previous studies on positive emotion, learning and motivation. In the present study, we examined the definition of positive emotion, and influences of positive emotion on cognition, creativity, social relationship, psychological resource such as life satisfaction, and interactive relationship among positive emotion, motivation and learning. To investigate the role of positive emotion on motivation and learning more scientifically, we examined the recent results of neuroscience. In other words, we have reviewed diverse research on positive emotion, learning and motivation based on brain-based learning. We also examined the research of autonomy-supportive environment as the specific example of improving positive emotion. As one of the most effective methods for emotional education, we discussed brain-based learning, the new research field. As the future prospects, we discussed the implications, possibilities and limitations of brain-based learning.

This study aims to investigate the relationship among public service motivation, hospital organizational culture type, job-esteem, and turnover intention of public hospital nurses. A cross-sectional study was conducted on 124 nurses at four public hospitals in the Gyeonggi Province (Icheon, Anseong, Suwon, Paju). Data were analyzed using descriptive statistics, t-tests, ANOVA, and Pearson correlation coefficient. Mann-Whitney U test and the Kruskal-Wallis test were used with the Bonferroni test for post hoc comparison when the data were not normally distributed. The turnover intention of the subjects was public service motivation (r=-.30, p<.001), affiliative culture (r=-.28, p=.002), innovative culture (r=-.34, p< .001) and task culture (r=-.30, p=.001) were negatively correlated. Study findings suggest that public service motivation must be increased to reduce the turnover intention of nurses in public hospitals.
