Abstract: The object of the present invention is to provide a ginsenoside composition which can obtain specific and excellent result in terms of efficacy, to various symptoms and diseases. The ginsenoside composition includes 3 components of Rb 1, Rg 3 (S), and Rg 2(S), which are ginsenosides, as an essential component. In solid base of the composition, the ginsenoside composition satisfies the following 3 requirements. That is, (Requirement 1): a content of the Rb 1 is 7.3 mg/g or more, (Requirement 2): a ratio of a content of the Rb 1 and a content of the Rg 3 (S), “Rb 1/Rg 3 (S)”, is in a range of 1.2 to 3.7, and (Requirement 3): a ratio of a content of the Rg 3 (S) and a content of the Rg 2 (S), “Rb 3 (S)/Rg 2 (S)”, is in a range of 1.7 to 4.4.

Abstract: The present invention relates to a method for establishing a connection between heterogeneous user-networks and a domain name system proxy server for controlling the same. The present invention has features of providing a method for supporting communication between user-computers included in Internet-compatible heterogeneous networks through a gateway based on an Internet public network and a domain name system proxy server for controlling the method. According to the present invention, supporting mutual communication between various networks based on one network can be expected.

Abstract: A multi-port memory device that prevents degradation of efficiency of a global data drive by turning off the switches, which do not discharge a global data bus. The multi-port memory device includes a global data bus, a banks, each bank including a transmitter and a receiver; ports, each port including a transmitter and a receiver; switches that operate to selectively connect the receivers of the banks and ports to the global data bus; and a switch signal generator for generating a switch signal in response to data drive pulses inputted to the transmitters of the banks and the ports.

Abstract: In a gamma correction digital-to-analog converter, one of first gamma correction reference voltage signals is selected as a first corresponding gray scale signal based on lower m+n bits of a k bit digital input signal when upper l bits of the k bit input signal correspond to an upper or lower code set, where k=l+m+n, and where k, I, m and n are integers. A pair of adjacent second gamma correction reference voltage signals is selected from second gamma correction reference voltage signals based on upper l+m bits when the upper l bits correspond to a middle code set, and one is selected from the pair of second gamma correction reference voltage signals and 2n?1 divided signals as a second corresponding gray scale signal, the divided signals being obtained by dividing an interval between the selected pair into 2n levels. The first or second gray scale signal is selected to be output.

Abstract: The present invention relates to novel hexa-arm polyethylene glycol (6-arm PEG) and its derivatives. The core of 6-arm PEG derivatives is sorbitol and the end groups can be derivatized into many different reactive functionalities that are useful in conjugating with many different targets. The present invention also provides a biodegradable polymeric hydrogel-forming composition comprising the 6-arm PEG and its derivatives, and methods of using such 6-arm PEG derivatives as surgical or biological implants or sealants.
