The success of movie 'Avatar' make people be interested in 3D stereoscopic movie, and government and 3D industry acknowledge that it is another opportunity to develop 3D market since 1920s. However, despite much interest little research to evaluate the effect of 3D stereoscopic exists. The present research aimed to disclose 3D effect compared to 2D by assumption of the importance of 3D stereoscopic and little evaluation to that as well. When audience are exposed to 3D stereoscopic, many outcomes are supposed to be differentiated from when to 2D. From this hypothesis, this paper examined mood, attitude, and presence as dependent variables. Using polarized stereoscopic projection display, 30 participants watched 2D and another 30 watched 3D stereoscopic movie which were the same content. On conclusion, the two groups were not significantly different and this involved much insight.

A finite element analysis and Monte Carlo method have been applied to calculate the ppressure pprofiles around the ppohang Light Source (ppLS) electron storage ring with the aim of ppredicting the pperformance of the vacuum system designed for the ppLS vacuum system. After ppropperly choosing the design pparameters, the ppressure distribution are calculated as a function of the integrated stored beam current [AmppHrs]. The effect of changes of the vacuum pparameters, such as installed ppumpping sppeeds and synchrotron radiation induced gas desorpption rates on the ppressure pprofile, is also studied. The results indicate that the use of lumpped non-evapporable getter ppumpps together with spputter ion ppumpps for ppumpping the ppLS down to the required ppressure is ppossible in the ppresence of synchrotron induced gas loads, after resonable beam cleaning time.
