With China Market and strengthening of an international and political position of China, we need to promote exchange and cooperation with China for the supplement of economic vitality and for contriving the contribution of the flow of growth. The necessity of salient traits is needed such as sharing information, training a specialist, network between China Specialists, system establishment of China information DB and sharing China information. Accordingly, KIEP makes the most of limited special manpower and information, and developed China Specialist Forum Website : CSF which will make a stepping stone of systematic, synthetic exchange and cooperation with China. KIEP presented a development direction, comparing and analyzing promptly easy to get the information China Specialists want here, CSF made for mutual exchange of science, trade and the other issue, Taiwan website "a commercial business intelligence network of China and Taiwan", and Singapore "IE Singapore".

The China's economy growth by expanded by almost 10 percent in the among ten year ago. Since the Korea and China ware established to 1992, The China has been Korea's most important trading partner. The subject of this study is to review export competitiveness in export entry type in the China's market of Korea company. This article measure the effects on Korea exporter interests of Korea's trade with china. This paper investigates the determinants of export competitiveness in export entry type in the China's market of Korea company. A survey questionnaire was sent to 200 sample in Korea's export company go to on the China market, and 137 usable responses were obtained. The 137 samples are analyzed with export competitiveness. This paper has there main a parts, Multiple regression results show that the export competitiveness are positively affected by the China Information, the China Culture Different, The CEO Mind and the China Trade System. However, The China Market Competitiveness, The China Law. Regime and manager's information do not affect in the export competitiveness.

The modular multilevel converter (MMC) has become a promising topology for high-voltage direct current (HVDC) transmission systems. To control a MMC system properly, the ac-side current, circulating current and submodule (SM) capacitor voltage are taken into consideration. This paper proposes a low-computation indirect model predictive control (IMPC) strategy that takes advantages of the conventional MPC and has no weighting factors. The cost function and duty cycle are introduced to minimize the tracking error of the ac-side current and to eliminate the circulating current. An optimized merge sort (OMS) algorithm is applied to keep the SM capacitor voltages balanced. The proposed IMPC strategy effectively reduces the controller complexity and computational burden. In this paper, a discrete-time mathematical model of a MMC system is developed and the duty ratio of switching state is designed. In addition, a simulation of an eleven-level MMC system based on MATLAB/Simulink and a five-level experimental setup are built to evaluate the feasibility and performance of the proposed low-computation IMPC strategy.

China has been aware of the urgent need of developing electronic and information industry in order to improve its productivity. Since 1991, IT industry has been one of the main factors to influence China's economic growth. In the results of the efforts to develop its IT industry, China has achieved average 25% yearly growth rate of IT manufacturing industry since 1991. We will take a look at haw the main IT products' performances was, how the role of IT industry was in China economy and in China's trade and how the prospect of China IT industry will be. However, we need to know that, depending an the different areas, the environment of the China's IT industry will be quite different. In China, the east coastal area has the better environment of technology, menpower, infrastructure, and fund for the development of IT industry and the IT industry of this area is very competitive, comparing with the middle and west area.

While the bilateral trade volume between China and U.S. has been growing rapidly, the trade deficits of U.S. to China has also been expanding. This growing trade deficit of U.S. to China has several reasons: the increase of foreign direct investment to China, the transfer of trade deficit origins, the intervention of U.S. domestic politics to China-U.S. trade relations, and U.S. direct control on export to China. However, the increased U.S. trade deficit to China does not mean that U.S. is in a disadvantaged position in its economic relations with China, or its international competitiveness is deteriorating. When U.S. surplus in service trade to China is included, the picture would be very different. Also, as internationalization progresses and China's industrial structure adjusts, the trade deficit of U.S. to China would narrow.

A microstrip dual-wideband bandpass filter using a multimode resonator (MMR) is proposed in this letter. The proposed MMR loaded with a T-shaped open-ended stub and a short-ended stub exhibits triple mode characteristics, and a synthesis method is developed to illustrate the wide passband with independently controllable center frequencies and bandwidths. To verify this design methodology, a dual-wideband filter with fractional bandwidths of 19.1% and 27.9% is designed and fabricated. The measured results agree with the simulations.

Compact multi-band bandpass filters using quad-mode stub-loaded resonators are proposed in this letter. Firstly, a novel approach about the mode-splitting characteristics of the quadruple-mode resonator is investigated, which can provide dual-band behavior. Secondly, a quad-band filter is proposed and designed by cascading two quadruple-mode resonators; the upper one operates at 1.8/2.4 GHz (GSM- and WiMax-band) and the lower one at 1.57/2.1 GHz (GPS- and WCDMA-band). Finally, the proposed filters have been fabricated. Respectable agreement between simulation and measurement verifies the validity of this design methodology.

In this paper, a model is proposed to comprehensively evaluate the computational power. The five forces model of computational power solves the problem that the measurement units of different indexes are not unified in the process of computational power evaluation. It combines the bidirectional projection method with TOPSIS method. This model is more scientific and effective in evaluating the comprehensive situation of computational power. Lastly, an example shows the validity and practicability of the model.
