  • Patent number: 9538526
    Abstract: Disclosed are a method and device for transmitting a frame. The method for transmitting a frame includes a step of generating A-MPDU (aggregate MAC protocol data unit) and a step of transmitting A-MPDU. The A-MPDU includes a first AMPDU subframe and a second A-MPDU subframe, wherein the first A-MPDU subframe includes a data block, and the second AMPDU subframe includes an FEC (Forward Error Correction) coding block which is additionally used in the decoding of the data block. Thus, the STA is capable of preventing unnecessary power consumption of STA by selectively determining whether FEC information is received according to whether an error occurred in the decoded data.

  • Publication number: 20160215018
    Abstract: A pharmaceutical composition for preventing or treating an ocular surface disease is disclosed, wherein the pharmaceutical composition includes, as an active component, collagen type II ?1 based peptide GQDGLAGPK isolated from chondrocyte-derived extracellular matrix (CDEM). In an alkaline burn animal mode treated with peptide GQDGLAGPK, the occurrence of corneal opacification is reduced as well as the expression of angiogenic factors (e.g., CD31 and VEGF). In addition, the expression of inflammatory markers (e.g., macrophages, TNF?, ICAM-1, VCAM-1, and MMP-9) is reduced while the expression of inflammation-inducing factor (e,g,, NF-?B) is suppressed. The peptide GQDGLAGPK according to the present invention may be applied to a pharmaceutical composition for preventing or treating an ocular surface disease (e.g., a corneal disease).
