사회적 네트워크 유형 별 내향 중심성이 직무 스트레스에 미치는 차별적 영향
신인용(In Yoing Shin),이기현(Ki Hyun Lee),오홍석(Hong Seok Oh) 한국경영학회 2013 經營學硏究 Vol.42 No.4
As interdependent tasks have been increasing and the necessity of smooth communication among employees has been emphasized in organizations, scholars and practitioners are interested in the effects of social support from social relationships on job stress. Drawing on a social network perspective, we examined that social ties among organizational members influenced the level of job stress which they experience. We especially expected that the types of social networks in which employees were embedded (task-advice networks, friendship networks, and negative affect networks) were respectively linked to the provision, reception, and absence of social support, which in turn led to differently affecting individual job stress. According to the results of this study based on the survey data from employees in two organizations, the persons who occupied in-degree centrality in friendship networks were more likely to receive social support from the other employees and then their levels of job stress reduced, whereas the employees who were located in in-degree centrality in negative affect networks were less likely to receive social support from the other members, resulting in increasing the level of job stress they experienced. In addition, we hypothesized the U-shaped relationship between in-degree centrality in task-advice networks and individual job stress. In other words, we anticipated that the central persons in task-advice networks to the certain level tended to experience lower levels of job stress by the increased sense of control and self-esteem about themselves, and beyond the optimum level they were likely to experience higher levels of job stress because they were excessively granted the role of providing social support to the others. However, this hypothesis was not supported. This study suggests that the extent of centrality by the types of social networks differently influences the levels of job stress which organizational membersexperience.

가상 변이맵 탐색과 수렴 조건 판단을 이용한 실시간 가상시점 생성 방법
신인용(In-Yong Shin),호요성(Yo-Sung Ho) 한국통신학회 2012 韓國通信學會論文誌 Vol.37 No.1A
본 논문에서는 양안식 3차원 디스플레이 장치에 사용가능한 실시간 가상시점 영상을 생성방법을 제안한다. 제안하는 방법은 변이 탐색 (disparity estimation) 과정에서 중복되거나 불필요한 계산을 제거하기 위해, 변이맵 탐색 위치를 가상시점과 동일한 위치로 설정한다. 또한, 전역 방법을 사용한 변이맵 탐색 과정은 정확도는 높지만 복잡한 계산량이 문제이기 때문에 최적화 과정에서 변이값이 수렴하는 위치를 탐색하고 정보 갱신을 멈추는 방법을 사용하였다. 이렇게 얻어진 가상시점의 변이맵은 실제 참조가 가능한 영역인지 판단하는 수렴 조건 판단 (convergence check) 절차를 거쳐 영상을 합성한다. 영상 합성을 위한 모든 과정은 실시간 처리를 위하여 단일 명령 복수 쓰레드 (Single Instruction Multiple Threads) 구조인 그래픽 처리장치(GPU)를 활용한 프로그래밍을 통해 고속화를 이루었다. 실험 결과를 통해 제안하는 방법이 합성 영상의 화질을 유지하면서도 실시간으로 가상시점 영상을 합성한 것을 확인할 수 있었다. In this paper, we propose a real-time view interpolation method using virtual viewpoint disparity estimation and convergence check. For the real-time process, we estimate a disparity map at the virtual viewpoint from stereo images using the belief propagation method. This method needs only one disparity map, compared to the conventional methods that need two disparity maps. In the view synthesis part, we warp pixels from the reference images to the virtual viewpoint image using the disparity map at the virtual viewpoint. For real-time acceleration, we utilize a high speed GPU parallel programming, called CUDA. As a result, we can interpolate virtual viewpoint images in real-time.

In this paper, we propose a fast depth-image-based rendering method to generate a virtual view image in real-time using a graphic processor unit (GPU) for a 3D broadcasting system. Before the transmission, we encode the input 2D+depth video using the H.264 coding standard. At the receiver, we decode the received bitstream and generate a stereo video using a GPU which can compute in parallel. In this paper, we apply a simple and efficient hole filling method to reduce the decoder complexity and reduce hole filling errors. Besides, we design a vertical parallel structure for a forward mapping process to take advantage of the single instruction multiple thread structure of GPU. We also utilize high speed GPU memories to boost the computation speed. As a result, we can generate virtual view images 15 times faster than the case of CPU-based processing.

x264와 GPU를 이용한 고속 양안식 3차원 방송 시스템
최정아(Jung-Ah Choi),신인용(In-Yong Shin),호요성(Yo-Sung Ho) 한국방송·미디어공학회 2010 방송공학회논문지 Vol.15 No.4
Since the stereoscopic 3-dimensional (3D) video that provides users with a realistic multimedia service requires twice as much data as 2-dimensional (2D) video, it is difficult to construct the fast system. In this paper, we propose a fast stereoscopic 3D broadcasting system based on the depth information. Before the transmission, we encode the input 2D+depth video using x264, an open source H.264/AVC fast encoder to reduce the size of the data. At the receiver, we decode the transmitted bitstream in real time using a compute unified device architecture (CUDA) video decoder API on NVIDIA graphics processing unit (GPU). Then, we apply a fast view synthesis method that generates the virtual view using GPU. The proposed system can display the output video in both 2DTV and 3DTV. From the experiment, we verified that the proposed system can service the stereoscopic 3D contents in 24 frames per second at most.
