Abstract: The present invention relates to a method for transmitting content and, more specifically, to a method for transmitting content, which can improve a response rate according to transmission of content and reduce traffic by providing content using a WAN optimization mode and a CDN mode when a cache device provides the content requested by a user terminal, and to an apparatus for the same. To achieve this, a cache device according to an embodiment of the present invention includes a communication unit, a storage unit, and a control unit. The communication unit communicates information with a cache controller connected to a user terminal and a content providing device. The storage unit stores divided chunk data for content to correspond to chunk identification information. When content transmitted to the user terminal is received through the communication unit from the content providing device, the control unit checks whether the content is stored in the storage unit every chunk unit. When it is determined that initial chunk data of the content is stored in the storage unit as a result of the inspection, the control unit controls the communication unit to transmit, to the user terminal, chunk data corresponding to chunk identification information transmitted from a cache controller. When the transmitted chunk data meets predetermined conditions, the control unit controls the communication unit to transmit sequentially remaining chunk data to the user terminal.

Abstract: The present invention relates to a marker and a kit for diagnosing and distinguishing aspirin exacerbated respiratory diseases (AERD) and aspirin tolerant asthma (ATA), containing plasma apolipopretein H. An ELISA is performed in order to identify and quantify ApoH in plasma between subjects of AERD and ATA. Eight protein spots indicate a relative strength difference between the collected plasma of the AERD (n=8) and ATA (n=8) subjects. In MALDI-TOF/TOF analysis, decreases in alpha-fibrino rps precursor, ApoH, fibrin beta, and proapolipoprotein levels, and increases in chain A human complement component C3, 90-kDa thermal shock protein, complement component C4a, and kininogen-1 isoform 2 are shown in AERD, when compared to ATA. The concentration of ApoH, according to the ELISA measurement results (P < 0.01), increased greatly in the plasma of the ATA subjects compared to the AERD and general control groups. The AERD shows changes in protein levels related to complement component pathways and thrombokinesis. Additionally, ApoH increases in ATA, compared to the AERD and general control groups, which indicates that ApoH is related to other causes of AERD and ATA.

Abstract: The present invention provides a method and an apparatus for determining a transport block size (TBS) in a wireless communications system. A TBS value is set in a manner that makes a code rate equal to or less than a threshold value for each number of physical resource block (PRB) pairs that can be assigned. A base station transmits, to user terminal, control information including modulation and coding scheme (MCS) information and resource allocation information. In addition, the base station generates a payload from a code block of the set TBS value and transmits the payload to the user terminal. The user terminal determines a TBS value based on the MCS information and resource allocation information, and receives downlink transmission by using TBS information. When a code block is segmented and transmitted, the size of a code block segment can be a size reducing performance degradation at a high code rate.
