Prospects for Monetary Cooperation in East Asia

The purpose of this paper is to reexamine the exchange rate policy of the Republic of Korea, and its role in promoting financial and monetary cooperation in East Asia in the wake of the 2008 global financial crisis. The Republic of Korea would not actively participate in any discussion of establishing a regional monetary and exchange rate arrangement as it is expected to maintain a weakly managed floating regime. The People’s Republic of China (PRC) has been fostering the yuan as an international currency, which will lay the groundwork for forming a yuan area among the PRC; the Association of Southeast Asian Nations (ASEAN); Hong Kong, the PRC; and Taipei,China. Japan has shown less interest in assuming a greater role in East Asia’s economic integration due to deflation, a strong yen, slow growth, and political instability. Japan would not eschew free floating. These recent developments demand a new modality of monetary cooperation among the Republic of Korea, Japan, and the PRC. Otherwise, ASEAN+3 will lose its rationale for steering regional economic integration in East Asia.exchange rate policy; republic of korea; financial monetary cooperation; east asia; global financial crisis; regional economic integration

Close-to-normal structure and its applications

AbstractLet K be a bounded subset of a metric space (B, d). Let W(K) be the supremum of the cardinals of all subsets H of K such that the distance between any two distinct points in H is equal to the diameter of K. This function W on the family of all bounded subsets of B is used to prove the following result. Let K be a weakly compact convex subset of a Banach space B. Then K has a close-to-normal structure if B satisfies any of the following conditions: (a) B is strictly convex; (b) B is separable; (c) B has the property A: For any sequence {xn} in B, {xn} converges to a point x in B if it converges weakly to x and {∥xn∥} converges to ∥x∥. Applications of this result to the fixed point theory are given

Numerical simulation and experimental study of PbWO4/EPDM and Bi2WO6/EPDM for the shielding of {\gamma}rays

The MCNP5 code was employed to simulate the {\gamma}ray shielding capacity of tungstate composites. The experimental results were applied to verify the applicability of the Monte Carlo program. PbWO4 and Bi2WO6 were prepared and added into ethylene propylene diene monomer (EPDM) to obtain the composites, which were tested in the {\gamma}ray shielding. Both the theoretical simulation and experiments were carefully chosen and well designed. The results of the two methods were found to be highly consistent. In addition, the conditions during the numerical simulation were optimized and double-layer {\gamma}ray shielding systems were studied. It was found that the {\gamma}-ray shielding performance can be influenced not only by the material thickness ratio but also by the arrangement of the composites.Comment: 8 pages,7 figures,Submitted to Chin.Phy.
