    摘要: A method and apparatus manages a buffer cache. An extended buffer is used to perform a page replacement algorithm using reference time information regarding a time at which a page is referred. Pages replaced through the page replacement algorithm, when re-referred to, may be retrieved from the extended buffer, instead of a hard disk. As a result, write/read operations with respect to the disk are made efficient and the page input/output speed is increased.

    摘要: A nystatin-resistant mutant microorganism belonging to Aspegillus genus is provided for preparing triol heptanoic acid, a precursor of 3-hydroxy-3-methylglutaryl-CoA reductase inhibitor. A mutant Aspergillus terreus CLS247-13, KCTC 0673 BP is prepared by treating Aspergillus terreus CLS216-7, KCTC 0359 BP with ultraviolet ray or chemical mutagens. The mutant provides high productivity (at least 11.5 g/L, 95/6% of the total product) of triol heptanoic acid, while reducing (less than 0.53 g/L, 4.4% of total product) productivity of triol heptanoic acid analogues. Since the nystatin-resistant mutant strain CLS347-13 has a capability of producing triol heptanioc acid with a high yield in a short period of culture time compared with known triol heptanoic acid producing strains, it can be widely used in industrial applications.
