摘要:
The present invention relates to glycolipoprotein gintonin, isolated and identified from ginseng, as a natural medicinal-plant-derived ligand acting on LPA1(lysophosphatidic acid; 1- or 2-acyl-sn-glycerol-3-phosphate), LPA2, LPA3, LPA4 and LPA5 receptors whose efficacy is exhibited physiologically/pharmaceutically via an interaction with subset receptors [LPA1(edg-2), LPA2(edg-4), LPA3(edg-7), LPA4, PLA5] in the EDG (endothelial differentiation gene) family in G protein-coupled receptors (GPCRs) present in the cell membranes of animals including humans. The gintonin of the present invention can be used to advantage in the prevention and treatment of various diseases arising from reduced calcium concentration and various physiological activities and pharmaceutical activities dependent on calcium, since the gintonin of the present invention interacts with LPA receptors so as to activate a series of signal transmission processes and temporarily induce an increase in free Ca2+ in the cytoplasm, and a temporary increase in the intracellular calcium concentration gives rise to a temporary increase in the intracellular calcium concentration in various organs including, inter alia, those of the nervous system, cardiovascular system, endocrine system, reproductive system, digestive system and immune system where the LPA receptors are expressed, with physiological activity being exhibited.
摘要:
Methods and apparatus are provided for supporting a variable-length transport packet in a audio and video communication system. Data to be transmitted through a transport packet is determined. A header of the transport packet is generated. The header includes a start sync signal. When a length of the transport packet exceeds a reference size, at least one intermediate sync signal is inserted into the transport packet according to a pre-defined interval. The transport packet is transmitted.

The present invention relates to an information storage medium having a plurality of recording layers, to a record reproduction method, and to a record reproduction apparatus. According to the present invention, the information storage medium has a plurality of recording layers, wherein each of the recording layers has an inner circumferential area and a data area. At least one of the plurality of recording layers has, in the inner circumferential area thereof, a temporary defect management area for recording information on defects detected in the data area. The size of the temporary defect management area in the upper layers is larger than that of the temporary defect management area in the lower layers.
摘要:
OPC (Optical Power Control) areas are efficiently arranged on an information storage medium with at least three layers according to the present invention so that data records of another layer are smoothly reproduced, reducing the influence of OPC operation during record reproduction. The information storage medium comprises at least three recording layers according to the present invention. Each recording layer comprises at least one OPC area. No OPC area of each recording layer overlaps with adjacent layers around a radius.
摘要:
Provided are a write-once disc, a method of using the write-once disc, and a data recording and/or reproducing apparatus. The method includes: allocating at least one spare area to a data area of the recording layers; and dividing each spare area into a sub spare area and a temporary disc management area in the direction in which user data is recorded. Here, the size of the temporary disc management area is greater than or equal to 1/N (N is a real number) of the size of one spare area.
摘要:
A write once disc includes a defect management area that is present in at least one of a lead-in area and a lead-out area; a temporary defect management area that is present in at least one of the lead-in area and the lead-out area; and a drive & disc information area that is present in at least one of the lead-in area and the lead-out area. Information regarding the locations of temporary defect information and temporary defect management information is recorded in the drive & disc information area, the temporary defect information and temporary defect management information, which includes drive & disc information, are recorded in the temporary defect management area, and temporary defect information and temporary defect management information, which are lastly recorded in the temporary defect management area, are recorded in the defect management area for disc finalization.
摘要:
Methods and apparatus are provided for supporting a variable-length transport packet in an Audio/Video (AV) communication system. Data to be transmitted is determined. It is determined whether a transport packet is the variable-length transport packet. A header having information indicating whether the transport packet is the variable-length transport packet is generated. When the transport packet is the variable-length transport packet, an optional header having length information of the transport packet is generated, and the data and the transport packet having the header and the optional header, are transmitted. When the transport packet is not the variable-length transport packet, the determined data and the transport packet having the header are transmitted.
