Prior research has examined various factors affecting cultural adaptation but the effects of the factors were assumed linear. Present study investigates the interactive effects of media use (TV & Internet) and interpersonal elements (FtF communication, phone conversation, and social network) on cultural integration. In addition the role of extrovertism was also examined. Results indicate that significant interaction effects exist between media use and FtF communication and media use and the social network. It was also found that individuals’ psychological characteristics such as extrovetism influenced cultural integration.

Weld quality monitoring and seam tracking along the butt-joint lengthwise to the tube axis are studied. The material of tube is 60kg/$\textrm{mm}^2$ grade steel sheet, and the longitudinal butt-joint is shaped by 2 roll bending machine. The tube with a thickness of 1.5mm, diameter of 105.4mm and length of 2000mm is successfully obtained by the $CO_2$ laser welding system equipped with a seam tracker and plasma sensor. Experimental results show that the developed welding system can be used for the precision seam tracking and the real-time monitoring of weld quality, and the laser welded tube can be used for car body md component after tubular hydroforming.
