  • Patent number: 9595673
    Abstract: The inventive concept shows the embodiment of t-switch which is a MIT 3-terminal device based on a Hole-driven MIT theory and a technology for removing an ESD noise signal which is one of applications of the t-switch. The t-switch includes three terminals of Inlet, Outlet and Control, and a metal-insulator transition (MIT) occurs at an Outlet layer by a current flowing through the Control terminal. In the t-switch, a high resistor is connected to the Control terminal and thereby an ESD noise signal of high voltage flows through the Inlet-Outlet without damaging the device.

  • Publication number: 20150358633
    Abstract: Provided is a video encoding method and apparatus for transmitting configuration information to accurately reproduce an image reconstructed by a decoder. Provided is a video decoding method and apparatus for receiving configuration information to accurately reproduce an image reconstructed by a decoder. The video decoding method includes: receiving a data stream including network abstraction layer (NAL) units; obtaining constraint information indicating whether there is a constraint on an arrangement type of samples of a picture from the data stream; and determining an arrangement method of reconstructed samples generated by decoding an encoded picture based on the constraint information.

  • Publication number: 20090254065
    Abstract: A method of transplanting an injectable chondrocyte is developed for autologous chondrocyte transplantation, comprising mixing matrices including fibrin, hyaluronic acid and collagen, which are the main ingredients of animal cartilage, and injecting the resulting mixture into a damaged cartilage region. One 1 ml syringe is prepared by mixing 1 ml of a chondrocyte culture with white or light-yellow lyophilized powder (fibrinogen). A second 1 ml syringe is prepared by mixing 1 ml of chondrocyte culture with white lyophilized powder (thrombin), adding 0.1 cc of that mixture to the entire contents of two vials containing chondrocyte suspension, and mixing well. The two syringes are then mounted on a syringe stand, and a mixing tip is mounted to their tips. The contents are mixed in the mixing tip while injecting the resulting mixture into a damaged cartilage region of an animal.

  • Publication number: 20070087032
    Abstract: A cartilage therapeutic composition is developed for clinical transplantation into articulatio genu (knee joints) or ankle joints. It has clinical significance for symptomatic cartilage defects of the femoral condyle (medial, lateral, or trochlear) and bone cartilage defects of the talus (anklebone) in human or animal hosts, The cartilage therapeutic composition comprises a mixture of components of chondrocytes isolated and expanded or differentiated from a host such as a human or animal, and thrombin and a fibrinogen matrix containing fibrinogen. An application of the cartilage therapeutic composition is that a mixture of thrombin, chondrocyte components and a fibrinogen matrix is injected into a cartilage defect region followed by solidification therein. It provides rapid healing and effective regeneration of cartilage without surgical operation. It has the merits of safety and simplicity by allowing the use of an arthroscope for transplantation.
