    摘要: The present invention relates to a method for differentiating stem cells into vascular cells by culturing them in the form of a three-dimensional cell cluster and the use of the three-dimensional cell cluster for angiogenesis. Specifically, the present invention teaches a method for differentiating stem cells into vascular cells comprising culturing stem cells by adhering them onto a culture plate with a surface having a hydrophobic property or a culture plate onto which a growth factor is immobilized, wherein the cultured stem cells are later detached from the culture plate as their density increases to form a three-dimensional cell cluster and grown in the form of a three-dimensional cell cluster while differentiating into vascular cells. Also disclosed is the use of a three-dimensional cell cluster composed of the vascular cells differentiated from stem cells by the above method as a cell therapy agent for angiogenesis.

    摘要: The present invention relates to a highly resilient (lactide/glycolide)/ε-caprolactone copolymer with good shape recovery force, flexibility, and biodegradability and a use of such copolymer for the repair of articular cartilage defects. The highly resilient (lactide/glycolide)/ε-caprolactone copolymer of the present invention is capable of rapidly and efficiently inducing cartilage regeneration, can be easily deformed and almost completely restored to its original form after deformation. Further, the highly resilient copolymer of the present invention can be safely and conveniently transplanted to a patient by using an arthroscope without causing economic, physical, and mental burden. Thus, the highly resilient copolymer of the present invention can be effectively used as a polymer scaffold for the repair of cartilage defects.

    摘要: An apparatus and method for efficiently operating a fast feedback channel in a wireless communication system are provided. A method for operating a feedback channel in a Base Station (BS) of a wireless communication system includes identifying feedback information types of one or more feedback channels intended to be deallocated among a plurality of existing allocated feedback channels for a Mobile Station (MS), activating a bit corresponding to the identified feedback information type in a ‘deallocation bitmap’ field within a DownLink (DL) control signal, and transmitting the DL control signal to the MS. Among the feedback information types of the plurality of existing allocated feedback channels, the feedback information type having the smallest value corresponds to the highest priority bit among bits within the ‘deallocation bitmap’ field.
