摘要:
The present invention relates to an efficient snapshot technique based on a mapping for a large logical volume shared in multiple hosts. According to the present invention, problems of time delays in a conventional snapshot technique is solved by employing a FAB and an SSB, which are bits representing whether a COW operation is carried out to a mapping entry. In other words, the present invention solves the problems of delaying a write operation of corresponding volume, which is simultaneously executed when a snapshot is created, until the snapshot creation is completed. Further, in the write operation carried out after the snapshot creation, an operation of determining whether the COW operation is carried out is achieved by reading only an original mapping block by using the FAB and the SSB, without reading out the snapshot mapping block. Therefore, an additional disk access operation is decreased when carrying out a write operation to the volume in which the snapshot exists, thereby improving the performance of operation. Furthermore, in a snapshot destruction operation, the operation of determining whether the COW operation is carried out or not can be achieved without access to the snapshot mapping block, thereby preventing the degradation of performance. In case there is at least one snapshot, the determination operation can be achieved by an access to the original mapping block. Consequently, constant performance is always provided without the number of the snapshots.

A prism sheet of an LCD includes a body part made of a transparent resin material and a plurality of polypyramid-shaped optical unit structures formed in a intaglio type on the body part. The plurality of optical unit structures have intaglio-type polypyramid shapes in an inside of their polygonal structure. A center of the intaglio portion corresponds to a vertex of the polypyramid, thereby forming a point.

Disclosed is a novel use of an immunoglobulin Fe fragment, and more particularly, a pharmaceutical composition comprising an immunoglobulin Fe fragment as a carrier. The pharmaceutical composition comprising an immunoglobulin Fe fragment as a carrier remarkably extends the serum half-life of a drug while maintaining the in vivo activity of the drug at relatively high levels. Also, when the drug is a polypeptide drug, the pharmaceutical composition has less risk of inducing immune responses compared to a fusion protein of the immunoglobulin Fe fragment and a target protein, and is thus useful for developing long-acting formulations of various polypeptide drugs.
