Abstract: A bitline precharge voltage generator comprises a leakage trimming unit and a bitline precharge voltage providing unit. The leakage trimming unit applies a leakage current to an output node to place a bitline precharge voltage at an edge of a dead zone. The bitline precharge voltage providing unit provides the bitline precharge voltage to the output node, and sets the bitline precharge voltage to a target level. The bitline precharge voltage generator generates the bitline precharge voltage having a distribution including the dead zone.

Abstract: A level detector, an internal voltage generator including the level detector, and a semiconductor memory device including the internal voltage generator are provided. The internal voltage generator includes a level detector that compares a threshold voltage that varies with temperature with an internal voltage to output a comparative voltage, and an internal voltage driver that adjusts an external supply voltage in response to the comparative voltage and that outputs an internal voltage.

Abstract: Disclosed herein is a method of extracting three-dimensional building information using shadow analysis. In the method, an image of a building captured through a manmade satellite, an airplane or some other means, and metadata to be used for extraction of building information is received, the azimuth and altitude angles of a sun in an area of capture, and the azimuth and altitude angles of a camera are calculated. The contour of the roof of the building, the location and height of which are desired to be obtained, is extracted from the image. A height value is assigned to the extracted contour of the roof of the building, and the height value is adjusted until the assigned height value satisfies a predetermined condition. The vertical line and shadow of the building, which are based on the height value, is projected onto the image.

Abstract: This invention relates to an anticancer agent comprising mycolactone, which induces apoptotic death of cancer cells and also relates to inhibitors of Rb protein expression, including an antisense Rb oligonucleotide, which sensitize cancer cells to mycolactone. This invention relates further to an anticancer agent comprising both mycolactone and the inhibitors of Rb protein expression. Mycolactone induces cell death in cancers of breast, bladder, skin, stomach, liver, colon, and oral cavity, lymphoma, and leukemia via apoptosis pathway.

Abstract: This invention relates to a mass preparation method of RmlC protein and the purified RmlC protein by the said method. RmlC is a gene product of rmlC, which is one of the biosynthesis genes of rhamnose that is an important element that consists cell wall of Mycobacterium tuberculosis. To be more specific, this invention improves the following disadvantage of recombinant RmlC protein of Mycobacterium tuberculosis previously reported that contains unnecessary 15 amino acids into the natural RmlC protein. This invention relates to a recombinant plasmid, a recombinant E. coli that is transformed by the plasmid, preparation method of Mycobacterium tuberculosis RmlC recombinant protein using the recombinant E. coli, purification method of recombinant RmlC protein, and the RmlC protein purified by the said method.

Abstract: A method for detecting Mycobacterium tuberculosis by the polymerase chain reaction (PCR) amplification of the REP13E12 repeated sequence, and more particularly, to a method for detecting Mycobacterium tuberculosis in clinical specimen by the PCR amplification of all or some of the REP1 3E1 2 repeated sequence is provided. Since the Mycobacterium tuberculosis detecting method by the PCR amplification for amplifying the REP13E12, which is the repeated sequence cloned from the microbial cells of Mycobacterium tuberculosis, which are separated from Korea, shows excellent sensitivity and specificity, it is possible to effectively detect Mycobacterium tuberculosis in specimen using the method.
