    摘要： An apparatus and method for transmitting a signal in a communication system. An information vector is encoded using a structured low density parity check (LDPC) coding scheme supporting a first coding rate, to generate a first structured LDPC codeword vector including a first part mapped to the information vector and a second part mapped to a parity vector. The first structured LDPC codeword vector is transmitted to a signal reception apparatus. If there is an error in the first structured LDPC codeword vector, the information vector is encoded using a structured LDPC coding scheme supporting a second coding rate, to generate a second structured LDPC codeword vector including the first part, the second part, and a third part mapped to an additional parity vector of the information vector. The third part is transmitted to the signal reception apparatus.

    摘要： Disclosed is a method of producing nanoparticles by using chemical curing. The method includes depositing a metal thin film on a substrate, applying an insulator precursor on a metal thin film, and adding a curing agent and a catalyst to the insulator precursor to perform the chemical curing. The method also includes mixing metal powder and an insulator precursor, applying a mixture on a substrate, and adding a curing agent and a catalyst to the mixture to perform the chemical curing. Since the chemical curing process is used in the method, it is possible to form nanoparticles by using a simple process at low cost while a high temperature process such as thermal curing is not used.

    摘要： According to the conventional process of separating necessary cells from a cell mixture containing specific cells tagged with magnetic beads, there is a problem in that separation process is complicated when the separation efficiency is high whereas the separation efficiency is relatively low when the separation process is simplified. The present invention provides an apparatus and method for separating cells from a cell mixture simply and efficiently through the processes of creating a cell mixture layer between upper and lower plates by adjusting a gap between the upper and lower plates and of adjusting a thickness of the created layer and separating the layer while applying a magnetic field to the layer from the upper plate, wherein the lower plate is provided with a cell mixture holding portion, in which the cell mixture containing specific cells tagged with magnetic beads is accommodated in an upwardly convex shape, at a top surface thereof and the upper plate is positioned above the lower plate to face each other and to adsorb the cell mixture accommodated in the cell mixture holding portion of the lower plate into a bottom surface thereof.
