The rise of eco-friendly personal electric mobility is a worldwide trend and the first Korean-made IT convergence electric skateboard, Youth Board, is developed to lead the trend. Youth Board is remotely controllable using either Youth Wearable Controller or Youth App through Bluetooth v4.0 communication, can speed up to 25 km/hr, and operating time is approximately 1.5 hr. A LED display located in the front side of Youth Board deck shows three different states to a rider for user convenience: remaining battery SOC, current driving speed, and braking amount. Indoor EMC test results between Youth Board and Youth Wearable Controller and outdoor Youth Board driving test results are analyzed. In particular, driving test results show the maximum current output is about 15% lowered compared to the other competitor electric skateboard and it lessens the power burden of the motor ESC. These results show Youth Board's usefulness as a personal mobility in the sense of small, light, and inexpensive aspects.

OSMU is now one of the most important keywords in the media industry. However, how to educate future media workers who can design and implement OSMU is an unsolved problem to media educators. In order to overcome the limitations of two perspectives of OSMU, namely economic perspective and storytelling perspective, this study propose a new OSMU education model for college students. Beginning with creating local content using MediaWiki, this model consists of five phases of media windowing, including MediaWiki, smartphone application, Web design, multimedia e-magazine for tablet PC, and publication. A Chuncheon-based university has been experimenting with this new OSMU education program. MediaWiki has played important role for creating local content collaboratively. All That Chuncheon application is now on service via SKT Tstore and Chuncheon Web pages has been designed successfully. Multimedia e-magazine and book publication is under preparation. The experiment has been successful so far, mainly due to the strategic choice of local content as the source of following media window. Also students have been strongly motivated for participating in this OSMU program.
