The recovery of stainless steel fiber by removing cutting oil from grinding swarf, which is classified as specified wastes, was investigated. Swarf loaded with grinding oil was regenerated by supercritical carbon dioxide. And, the effects of temperature(313.15K-323.15K), pressure(10MPa-30MPa) on regeneration efficiency were studied. Regeneration effiency was increased as the pressure was increased. Also, at the same pressure, the experiments at higher temperature were more efficient for regeneration. The experiment results was predicted by applying a one-parameter mathematical model assuming linear desorption kinetics. The predicted value showed good agreement with experimental data.

올해들어 원유가격 및 국제금리의 하락과 수출호조에 힘입어 경상수지가 큰 폭으로 개선됨으로써 종전에 거액의 통화를 환수해 온 해외부문이 금년에는 통화철조부문으로 전환될 전망이며, 앞으로 해외부문에서의 통화증발압력이 가중될 것으로 예상됨에 따라 통화당국은 지난 7월중 무역금융 융자단가를 인하하고, 통자안정증권발행을 확대하는 등 금융면에서 통화환수노력을 경주하는 한편, 외환부문에서도 단기자본도입억제를 위하여 연지급수입기간을 단축한 바 있다. 이에 이어 지난 8월 21일에는 최근증가추세에 있는 외자대출을 억제하기 휘하여 융자대상 및 융자기간의 축소와 함께 융자비율을 인하하였으면 연지급수입대상품목을 축소하였다. 또한 외국은행 국내지점의 양도성예금증서(CD)업무 취급허용과 함께 외국은행 국내지점 스와프 한도를 축소하고 외국환은행의 수입보증금 징수대상을 기한부수입에도 확대 적용하는 등 일련의 외환부문 통화대책을 추가적으로 실시하였다.

During the global financial turmoil in 2007-2008, deviation from the covered interest parity (CIP) between the Korean won and US dollar through the foreign exchange swap has escalated in its magnitude beyond 1,000bp in November 2008, and it still persists around 100bp level. In this paper, we examine a newly developed margin based asset pricing model using Kalman filter approach and show that the escalation of the CIP deviation is found to be significantly related to the global dollar funding illiquidity and country-specific funding conditions. Furthermore, we find evidence that the poor funding conditions (or higher margins) are driven by the general money market illiquidity and may lead to higher funding illiquidity, which suggests the reinforcing effects of the liquidity spiral. We also show that the supply of dollar liquidity and improved funding conditions help alleviate the deviations from the parity, however the persistent anomaly is found to be related to the high level of volatility in the FX swap market.
