Abstract:
Disclosed is a method of preparing a metal oxide-graphene nanocomposite, including preparing a nanocomposite material, forming graphene flakes by pretreating the nanocomposite material, and hydrothermally synthesizing the pretreated nanocomposite material. A method of manufacturing an electrode using the metal oxide-graphene nanocomposite is also provided. According to this invention, the metal oxide-graphene nanocomposite is synthesized from inexpensive graphite through one-step processing using only a surfactant, in place of conventional methods using oxidants, reductants and high-temperature heat, thereby lowering the number of processing steps and processing costs. Also, in the fabrication of the electrode, low electrical resistance characteristic of graphene is applied as it is, in place of the conventional use of active material, conductive material and binder, thereby exhibiting desired processing efficiency without the addition of the conductive material. Furthermore, highly pure graphene is prepared in a short time and various metal oxide active materials suitable for use in energy storage devices, for example, unary, binary, and multicomponent metal oxides, is formed through one-step processing, and necessary oxides having desired weight ratios {cobalt oxide (CoO), tricobalt tetraoxide (Co3O4), and cobalt hydroxide [Co(OH)2]} can be easily prepared, and thus very wide application ranges (secondary batteries, gas sensors, etc.) are expected.
Abstract:
The present invention is directed to a method of calculating the results of a moving k-nearest query and safe exit locations in a road network, and more particularly to a method and apparatus that receive a request from a client terminal and provide the results of a k-nearest query, a safe zone and safe exit locations together. In the present invention, a query is processed in a server, a request for a query from a querying user and the location information of the querying user are received from an LBS, the location information of the querying user is anonymized and then the query request is transferred to the server, and query results corresponding to the anonymized location information of the querying user are received from the server and then transferred to the querying user, thereby protecting the location information of the querying user.
Abstract:
The present invention generally relates to a communication method and apparatus using a slot-based channel and, more particularly, to technology for estimating slot-based channel values in real time so as to perform Analog Network Coding (ANC) or full-duplex communication in a single slot. In order to achieve the object, a communication apparatus using a slot-based channel according to an embodiment includes a transmission unit, a channel estimation unit, and a decoding unit.
Abstract:
The present invention relates to a process for enhancing stem cell bioactivity using tauroursodeoxycholic acid (TUDCA) or a pharmaceutical acceptable salt thereof.
Abstract:
Disclosed herein is a hydrogen detecting sensor that includes a sulfide-metal catalyst, such that hydrogen gas can be detected visibly with naked eyes. Particularly, the hydrogen detecting sensor includes a substrate, a sulfide layer formed on the substrate and chemically discolored when exposed to hydrogen, and a metal catalytic layer formed on the sulfide layer.
Abstract:
A pharmaceutical or health food includes rapamycin as an active ingredient, the pharmaceutical or health food being applied for prevention, improvement, and treatment of ototoxic hearing loss caused by an aminoglycoside-based antibiotic, sudden sensorineural hearing loss, and noise induced hearing loss. The pharmaceutical or health food is also applied to a pharmaceutical composite preparation of an aminoglycoside-based antibiotic and rapamycin, the pharmaceutical composite preparation reducing a side effect of the aminoglycoside-based antibiotic.
Abstract:
The present invention relates to a pharmaceutical composition for treating or preventing diseases caused by vascular permeability, containing imatinib, which has been conventionally used as an agent for treating chronic myeloid leukemia, or a pharmaceutically acceptable salt thereof as an active ingredient, and a method for treating disease caused by vascular permeability using the composition. The pharmaceutical composition for treating or preventing diseases caused by vascular permeability of the present invention contains imatinib, which has been conventionally used as an agent for treating chronic myeloid leukemia, as an active ingredient, so as to provide a novel use of imatinib and to be able to effectively treat or prevent diseases caused by vascular permeability, and thus may be widely applied to develop a novel agent for treating diseases caused by vascular permeability.
Abstract:
Provided is a method of decoding a low-density parity-check code (LDPC). The decoding method including an initialization process, a check node update process, a variable node update process, a tentative decoding process, and a parity check process, for a plurality of check nodes and a plurality of variable nodes, further includes detecting at least one inactive variable nodes that do not require variable node update among the variable nodes, the variable node update process is performed only on active variable nodes except for the inactive variable node, and the check node update process is performed without using the inactive variable node.
