Abstract:
A sealant forming device, a sealant forming method and a method for manufacturing a liquid crystal display device using the same are disclosed. According to the present invention, a sealant coagulated in a nozzle can be minimized or prevented by performing an instantaneous suction process. A sealant forming device includes a dispenser including a syringe, and a nozzle connected to a lower end of the syringe to discharge a sealant therethrough; a dispensing tube connected to the syringe to apply a pressure to the syringe; and an instantaneous suction tube connected to the syringe to extract the sealant remaining in the nozzle after discharging the sealant.
Abstract:
Provided is an apparatus and method for transmitting a channel sounding signal from a user terminal in a multiple antenna system. In the method, a channel for each of a plurality of antennas is estimated. The receiving signal power of each of the antennas is calculated using the channel information obtained through the channel estimation. The antenna with the highest RX signal power is selected. Therefore, it is possible to enhance the signal reception performance of the user terminal.
Abstract:
An apparatus for decomposing a channel in a closed-loop Multiple Input Multiple Output (MIMO) communication system is provided. The channel decomposition apparatus includes a transmitter for preceding input symbols using a first matrix which is a product of a unitary matrix V, a diagonal matrix Φ and a blockwise Uniform Channel Decomposition (UCD) matrix PBL, before outputting the input symbols.
Abstract:
An apparatus and method for detecting a signal in a Multiple-Input Multiple-Output (MIMO) system are provided. The method includes filtering each stream of a received signal, acquiring a new search space by acquiring a set of candidates having reliability greater than a threshold with respect to each filtered stream, and detecting a signal for each stream of the new search space.
Abstract:
The present invention provides a circular dumbbell oligodeoxynucleotide (CDODN) comprising two loop structures and a stem structure, wherein the stem structure comprises a nucleotide sequence capable of binding the DNA-binding domain of a transcriptional factor. The present invention further provides a pharmaceutical composition comprising said CDODN. The pharmaceutical composition can be used for treating and/or preventing a disease or disorder related to such a transcriptional factor. The present invention also provides a method for treating and/or preventing a disease or disorder related to such a transcriptional factor, comprising administering to the subject a therapeutically effective amount of a CDODN comprising two loop structures and a stem structure, wherein the stem structure comprises a nucleotide sequence capable of binding the DNA-binding domain of the transcriptional factor.
Abstract:
An apparatus for coding a pseudo orthogonal space-time block code in a transmitter using 4 transmission antennas of first to fourth transmission antennas. Upon receiving information symbol streams x1x2x3x4 to be transmitted, a serial-to-parallel converter parallel-converts the received information symbol streams x1x2x3x4 into x1,x2,x3,x4. A pseudo orthogonal space-time block coding (PO-STBC) encoder codes the parallel-converted information symbol streams x1,x2,x3,x4 using a pseudo orthogonal space-time block coding scheme such that the information symbol streams x1,x2,x3,x4 are transmitted via corresponding transmission antennas for first to fourth time periods.

Abstract:
Provided is a process for preparing a compound of formula 1 or its salt. The process includes reacting a compound of formula 4 with acetaldehyde in a mixed solvent including water, isopropanol, and methylenechloride in a volume ratio of 1:3-6:11-14 in the presence of a first base to stereospecifically prepare a compound of formula 3 and reacting the compound of the formula 3 with an anhydrous compound of formula 2 in the presence of a second base.
Abstract:
Disclosed is a method of producing teicoplanin. The method includes purifying teicoplanin from a culture broth, obtained by culturing microorganisms capable of producing teicoplanin by a porous adsorption resin under selective elution conditions and recovering highly pure teicoplanin using activated carbon and/or ultrafiltration. In this regard, the method can further include ultrafiltration as pre-treatment before the culture broth is adsorbed into the porous adsorption resin so as to increase the purity of teicoplanin.
