A new progressive advanced approach (Loop thermosyphon Thermoelectric Power generation System) is suggested to optimize heat recovery from vehicle exhaust gas. The present thermoelectric generators (TE) system offers the potential to increase vehicle fuel economy by converting a portion of engine waste heat to electricity. The feasibility of TE system is assessed in the context of hybrid electric vehicles. The present new TE system adopted heat pipes as a cooling heat exchanger of TE module. The present simulation study has been performed with CFD thermal modeling tool. In the present study, the proposed TE generation system for the future hybrid car could be recognized as the new waste heat recovery system. It was observed that the power output of the present TE generation system affected by various variables such as cooling media, thermal contact and supplied power etc. The present simulation results with the heat pipe TE module shows possibilities as an improved TE system for future thermoelectric hybrid vehicles.

This study analyzed an effect of Korean electronic industry on the export to EU by European financial crisis through the empirical research. And, based on it, this study analyzed coping strategies of export to EU advanced to EU. As the result of analysis, when European financial crisis kicked into high gear, export to EU in 2011 was significantly reduced in comparison with the past, and exports to Germany, Italy and Spain were significantly reduced. For the coping strategies of export enterprises for domestic slowdown, quality improvement of export enterprises was suggested. And, for the coping strategies for overseas markets shrinking, technological development of business multi-changes was suggested.
