이동성이 중요시되는 네트워크에서 특정 프로토콜의 성능 평가를 위해서는 노드의 이동패턴을 정확하게 표현할 수 있는 Mobility Model이 필요하다. 노드의 연속적인 이동패턴을 필요로 하는 Mobile Ad-hoc 네트워크를 위해선 Markov process 기반의 Gauss-Markov Mobility Model이 적절하다. 그러나 맵의 엣지 부근에서 노드 이동의 부적절한 처리로 인해, 기존의 Gauss-Markov Model은 편중된 이동 패턴을 야기한다. 본 논문은 엣지 부근의 평균 이동각도를 랜덤하게 조정함으로써 기존의 모델이 가진 문제를 해결하고, 시뮬레이션을 통해서 이를 검증한다.

This study analyzes the influence of the four components of authentic leadership on employees' OCB and job performance to suggest the implications behind the developing of authentic leadership. A survey was conducted on employees of various business areas in Korea, and 448 responses were used in statistical analysis. The results are as follow: First, self-awareness has not shown significantly effective on organizational citizenship behavior and job performance. Second, internalized moral perspective has shown significantly effective toward organizational citizenship behavior and job performance. Third, relational transparency has shown significantly effective for organizational citizenship behavior, but not effective for job performance. Forth, balanced processing of information has not shown significantly effective on organizational citizenship behavior and job performance. This paper makes significant contribution by considering the supervisor's relational transparency and internalized moral perspective, because these authentic leadership dimensions improve employees' OCB and job performance.

The ppuri industry is growing in technical importance due to the 4th industrial revolution and is growing steadily. However, securing skilled workers is hardly realistic, and foreign workers are increasing. The purpose of this study is to find organizational commitment on for improvement of in-role performance of foreigners and Koreans working in ppuri companies and to find ways to support differentiation through comparison between groups. The subjects of this study were foreigners and Koreans in the ppuri company. Through the survey, 393 valid samples were collected. We use structural equation modeling to verify the research hypotheses, and conducted a survey on the employees of organization with information security policy. The results showed that in the case of foreigners, balanced processing affects in-role performance through organizational commitment. In the case of Koreans, relational transparency, balanced processing, and internalized moral perspectives affect in-role performance through organizational commitment. The results of the analysis suggest a strategic approach to improve the in-role performance of each group.
