More specifically, provided are glycidyl dinitropropyl formal of chemical formula IV having a nitro group (—NO2) as an energy group and having no hydrogen bonding to carbon to which the nitro group is binding, poly(glycidyl dinitropropyl formal) of chemical formula V polymerized using the glycidyl dinitropropyl formal as a monomer, and a preparation method thereof.
摘要:
A synthesis of an energetic prepolymer used as a high-energy binder for an insensitive and high performance explosive is disclosed. More specifically, provided are a novel compound 2-nitratoethyl oxirane expressed by formula III, a novel compound poly(2-nitratoethyl oxirane) expressed by formula IV, obtained by polymerization of 2-nitratoethyl oxirane used as a monomer and a preparation method thereof. The compound, used as an energetic prepolymer and a monomer for preparation thereof can substitute for existing poly(glycidyl nitrate) (PGN) which has been known to be a promising one having the best performance among existing energetic prepolymers, but which has a problem to be self-decomposed after synthesis of polyurethane elastomer, to solve this problem.
摘要:
Provided are an apparatus and method for enhancing an image using a color channel. A pre-processing unit generates an inverted image by inverting a luminance component estimated from a red (R) channel among color channels of a red, green, and blue (RGB) color space of an input image. A channel merging unit generates a merged luminance (L) channel by merging an L channel of an International Commission on Illumination (CIE) L*a*b* (CIELab) color space of the input image and the inverted image. A contrast enhancement unit enhances contrast by expanding a histogram of the merged L channel. A color restoration unit combines the merged L channel whose contrast has been enhanced and chromaticity components of the input image, and converts a resultant color image to the RGB color space, thereby generating a restored image.

An apparatus and method for supporting prototype development of an embedded system are provided. The apparatus includes: a requirements analysis unit analyzing information about requirements and use cases of the embedded system which are input by a user to create a use case analysis table; an architecture design unit analyzing at least one of software and hardware structures of the embedded system which are input by the user and constituents of each of the software and hardware structures to create a structure graph for system, and reflecting the created structure graph for system in the use case analysis table created by the requirements analysis unit to update the use case analysis table; an architecture behavior definition unit defining behavior information including an execution flow and call relationship between the constituents defined by the architecture design unit; an integrated implementation unit creating a code so that the constituents defined by the architecture design unit operate according to the behavior information defined by the architecture behavior definition unit, and implementing the system while checking whether or not a function of each constituent is executed; and a test unit testing function and performance of the implemented system. Thereby, the system development based on the design mixing the hardware and software can divide changes and corrections that can take place during the development process at a high level of a development initial step, so that the system can be constructed from the ground up.

The present invention relates to a monoclonal antibody specific for N-myc downstream regulated gene 2 (NDRG 2) protein, a cell line producing the monoclonal antibody, a method for measuring a quantity and quality of NDRG 2 protein, and a protein chip using the same. In the present invention, NDRG 2, a cancer-related factor is specifically expressed in dendritic cells differentiated from a monocyte of human peripheral blood. Accordingly, the monoclonal antibody specific for the NDRG 2 protein, the protein chip comprising the same and the method for measuring a quantity and quality of the NDRG 2 protein by using the same can be applied to elucidate characteristics of the dendritic cell and perform a research on the NDRG 2. Therefore, the present invention may help clinically to investigate and treat intractable diseases and cancers using the dendritic cell.

A lithium ion secondary battery is provided. The lithium ion secondary battery generally comprises an electrode assembly, a container for accommodating the electrode assembly; and an electrolyte. The electrode assembly comprises two electrodes having opposite polarities and a separator. The separator comprises a porous membrane comprising clusters of ceramic particles. The porous membrane is formed by bonding the particle clusters with a binder. Each particle cluster is formed either by sintering or by dissolving and re-crystallizing all or a portion of the ceramic particles. The ceramic particles comprise a ceramic material having a band gap. Each particle cluster may have the shape of a grape bunch or a lamina, and may be formed by laminating scale or flake shaped ceramic particles.
