Supply chain for the economic development of East Asian economic development model, the study's purpose is to establish. Korea, Japan, China, Russia and Asia, including North Korea and get the status of economic development by focusing on key issues and proposed solutions, within a few years of the coming of a new East Asian economic integration of new supply chain would like to prepare for the era. Weight The weight of the center to the center of East Asia, looking for techniques to approach the supply chain scenario, the economic development strategies and measures were studied. East Asia's economic potential value of the supply chain, identify and recognize the importance and benefits should be Presents detailed country-specific development strategies and leading Asian economies will have to pay the supply chain. Republic of Korea's leading East Asian economies in order to supply the industry, industry development strategy as detailed in the running to move. North and South Korea for economic integration, the era of supply-chain economy, you need to prepare calmly.

Recently, A N2 gas generator has become a very popular issue in application to semiconductor production process. An experimental study has been carried out to investigate the production performance as a N2 purity and production of N2 gas generator. The N2 gas generator used a small size system with two adsorption towers and an air compressor as flow rate 20 m3/h. The N2 gas generator system size is width 2270 mm, length 850 mm and height 2135mm. An experimental data has been measured as the variation of a adsorption temperature, adsorption pressure and adsorption time. The results indicate that the N2 gas production increase in case of decreasing adsorption temperature, increasing adsorption pressure and decreasing adsorption time. The N2 purity is highest value of 99.93% when the governor orifice diameter is 0.5 mm.
