Abstract:
Disclosed are a competition-based multiview video encoding/decoding device and a method thereof. The competition-based multiview video encoding/decoding device can improve encoding efficiency by determining a prediction vector with the best encoding performance through an extraction of a spatial prediction vector, a time prediction vector, and a viewpoint prediction vector corresponding to a current block.
Abstract:
Disclosed are a multi-view video encoding/decoding apparatus and method. The multi-view video encoding apparatus encodes the current block which is to be encoded and which belongs to a frame of a first view point, wherein the encoding is performed in accordance with a first skip mode using the frame of the first view point or a second skip mode using the frame of a second view point, thereby improving encoding efficiency.
Abstract:
Provided is a method for preparing high-purity lithium carbonate from brine. According to the present invention, the method for preparing lithium carbonate from brine is characterized by comprising the steps of: removing magnesium ions from brine; adsorbing lithium ions by introducing an adsorbent into the brine from which the magnesium ions were removed, and then desorbing the lithium ions by introducing the adsorbent having the adsorbed lithium ions into a strong acid solution; concentrating the strong acid solution in which the lithium ions are desorbed; and enabling the lithium ions contained in the concentrated solution to chemically react with carbonate precursors to obtain lithium carbonate.
Abstract:
Disclosed are a method and apparatus for an adaptive HTTP streaming service using media content metadata. The media content consist of a series of periods. The metadata may include a start time attribute and/or a duration attribute for each period. The metadata may determine a start time of each period and a start time of each segment contained in each period. A terminal accesses the segments contained in each period, and performs decoding and rendering processes on the data of the media content contained in the segments, thereby reproducing the media content.
Abstract:
Disclosed are an apparatus and method for providing an adaptive HTTP streaming service using metadata for content. The metadata includes one or more base URL elements. The URL of a segment constituting media is generated on the basis of one or more base URL elements. The URLs of the segment may be generated by mapping any of the one or more base URL elements into a source URL property of the segment. The generated URLs indicate the same segment.
Abstract:
The present invention relates to a novel use of benzo-heterocycle derivatives, and more particularly, to a composition for preventing and treating cancer, comprising benzo-heterocycle derivatives or pharmaceutically acceptable salts thereof as active ingredients. The inventors of the present invention have found that KRS interacts with 67LR to promote the migration of cancer (or tumor) cells and thus affects the metastasis of cancer, and also have identified that the substance which inhibits the interaction between the KRS and 67LR suppresses the metastasis of cancer cells, and thus can be used for preventing and treating cancer. Accordingly, the composition of the present invention suppresses the metastasis of cancer, and therefore provides a novel means for preventing and treating cancer.
Abstract:
The present invention relates to an enzymatic fuel cell using a DNA-wrapped carbon nanotube, and more specifically to an electrode for an enzymatic fuel cell comprising a DNA-wrapped carbon nanotube which is adsorbed to the electrode and an enzyme immobilized on the DNA-wrapped carbon nanotube, an enzymatic fuel cell using the same, and manufacturing method thereof. According to the present invention, the activity of the enzyme used for an enzymatic fuel cell and safety can be improved by manufacturing an electrode for fuel cells by means of a DNA-wrapped carbon nanotube and applying the electrode for fuel cells to an enzymatic fuel cell. Therefore, the power density of the enzymatic fuel cell using a DNA-wrapped carbon nanotube can be higher than that of conventional enzymatic fuel cells not using a DNA-wrapped carbon nanotube and be stable for a long time.

Abstract:
The present invention relates to a memory card-based conditional access system (CAS) for mobile broadcasts that enables CAS services to be handled in the memory card. To this end, the present invention executes the generic bootstrapping architecture (GBA) between the CAS client and the bootstrapping service function/home subscriber system (BSF/HSS) in the memory card loaded in the CAS client so that the memory card loaded in the CAS client shares a shared key (KS) with the BSF/HSS. In addition, a long-term key message (LTKM) received from the CAS server is encrypted with a subscriber management key (SMK) induced from the KS to obtain a service encryption key (SEK) (or program encryption key (PEK)) to provide a traffic encryption key (TEK), and it is preferable that safe delivery to the descrambler of the TEK thus obtained be effected in the memory card. The present invention executes the decryption of the keys (SMK, SEK/PEK, TEK) and messages, including GBA, required to view the encrypted contents, within the memory card, thereby ensuring safe management of the keys (SMK, SEK/PEK, TEK).
Abstract:
Disclosed herein are novel microbes Thraustochytrium sp. KJS-1 and Bacillus polyfermenticus KJS-2. Also provided is an aquaculture feed additive for use in fisheries, which comprises freeze dried Thraustochytrium sp. KJS-1, freeze dried Bacillus polyfermenticus KJS- 2, and freeze dried Bacillus licheniformis.
