Abstract

The present invention relates to a block chain-based file management and search system, wherein it is possible to check data name and owner. In the file management and search system, when generated data is stored and a data name is delivered in the form of a transaction to another node together with the IP address and port number information of a node in which the data is stored, nodes receiving the same generate blocks on the basis of said transaction and connect the blocks to a blockchain so that the data name and information about an owner who generated the data is shared by everybody. Since this information is recorded on the blockchain, all of the nodes share the same information. Therefore, in order for a malicious node to arbitrarily modify content, it is necessary for the malicious node to modify the blockchain content owned by all of the nodes. Accordingly, arbitrary modification is practically impossible, and thus the blockchain is inherently highly secure.

Abstract

By forming a monolayer of metal core-shell nanoparticles, transferring the monolayer to various substrates and removing the shells surrounding the particles by way of selective etching, it is possible to form large-area uniform nanogap structures very easily. In addition, a nanogap is formed by an ultrasmall void having no limitation in diffusion between metal cores through Van der Waals interaction between the metal core particles, as the etching proceeds. It is possible to enhance a near-field significantly around the nanogap structure.

The present invention relates to a proton-transport vesicle and a method for preparing the same, the proton-transfer vesicle comprising: (a) a single phospholipid bilayer liposome; (b) a rhodopsin protein; and (c) a photosystem Ⅱ protein, wherein the rhodopsin protein and the photosystem Ⅱ protein are inserted and located in a bilayer of the liposome. Since the heterologous photosensitive proteins are inserted and located in the bilayer of the liposome, the vesicle has an absorption wavelength band of the whole region of visible light by utilizing absorption bands of different lights of the respective photosensitive proteins. Thus, the restricted efficiency caused by utilizing only a specific wavelength in existing organisms or artificial vesicles was improved, and the wavelength region can be enlarged to the all wavelength ranges of visible light. Meanwhile, the use of the fusion system of the rhodopsin protein and the photosystem Ⅱ protein improves the pumping capacity efficiency of hydrogen ions inside and outside a phospholipid membrane of an existing protein, and thus, the fusion system is expected to be applicable to the extracellular production of ATP or industrially usable in various fields, such as a photocatalyst and a solar cell.

According to the present invention, the present invention makes it possible to effectively selectively cause the death only of undifferentiated induced pluripotent stem cells by causing induced pluripotent stem cells to differentiate into specific differentiated cells and then carrying out culturing in a differentiating culture medium comprising quercetin or YM-155, and, in the induced pluripotent stem cell differentiation method according to the present invention, only undifferentiated induced pluripotent stem cells that are a cause of teratoma formation are selectively caused to die, and thus differentiated differentiating cells are completely unaffected. In other words, the invention can be expected to ensure safety as the possibility of tumour formation during clinical use as a cell therapeutic agent is eliminated since the survival and functioning of the differentiated cells is maintained unchanged.

The method for transmitting channel quality information by a terminal in a wireless communication system that supports coordinated multipoint (CoMP) technology, comprises the steps of: receiving information on a plurality of transmission nodes capable of performing CoMP transmission; transmitting first channel state information on one or more preferred transmission nodes from among the plurality of transmission nodes; receiving pattern information consisting of a plurality of combinations of CoMP sets, each of which corresponds to a relevant time interval according to the pattern information; and performing an operation for transmitting second channel state information on the combination of CoMP sets corresponding to a subframe n. When the combination of CoMP sets corresponding to the subframe n is overlapped with said one or more preferred transmission nodes, the second channel state information is transmitted. When the combination of CoMP sets corresponding to the subframe n is not overlapped with said one or more preferred transmission nodes, the second channel state information is dropped.

Abstract

The present invention relates to a scanning interference microscope. The scanning interference microscope according to the present invention comprises: a light source; a polarized beam splitter (PBS); an acousto-optic (AO) device; an AO driving unit for driving the AO device according to a modulated frequency (fRF) for dithering within a frequency variable range (Δf) and on the basis of a center modulated frequency (fRF0); a photodetector for detecting an interference signal of a signal light and a reference light; an RF demodulator using a modulated frequency in order to demodulate and output the interference signal; a lock-in amp using a dithering frequency (fdithering) in order to demodulate and output a signal supplied from the RF demodulator; a function generator for generating a dithering signal having a preset amplitude (A) and the dithering frequency (fdithering) and supplying the generated dithering signal to the AO driving unit, and supplying the dithering frequency (fdithering) to the lock-in amp; and a controller using a signal outputted by the lock-in amp in order to detect information on a sample. The scanning interference microscope according to the present invention uses the AO device, which is capable of: varying the modulated frequency in order to obtain information on a local slope of the sample, in order to be able to accurately measure the surface of the sample; and measuring the amount of change in the overall slope of the sample caused by an external change (noise), so as to be capable of taking a more stable measurement.
