Abstract: An injector for an implant for an eye disease includes: a cannula comprising an inner space in which at least a part of the implant for an eye disease comprising a ripcord is to be accommodated, and an implant opening into which the implant for an eye disease is to be inserted; a handle part connected to the cannula and to be held by an operator, and a holder configured to be coupled to the handle part and comprising a receiving part in which the ripcord of the implant for an eye disease is to be accommodated.

Abstract: Disclosed herein is a multi-bank type semiconductor memory device which reduces current consumption of data lines. In the multi-bank type semiconductor memory device according to the present invention, the data lines between each memory bank and an input/output buffer are divided into horizontal data lines and vertical data lines. In addition, a high impedance driver is provided to drive horizontal local data of the horizontal data line to provide the horizontal local data as vertical local data of the vertical data line. Therefore, in the multi-bank type semiconductor memory device according to the present invention, even when the horizontal local data and the vertical local data are controlled at a low power voltage, degradation in overall operating speed hardly occurs. In addition, in the multi-bank type semiconductor memory device according to the present invention, current consumption in the data lines is significantly reduced.

Abstract: Disclosed is a basic culture medium for mesenchymal stem cells, and a cell therapeutic agent cultured and differentiated using same. The basic culture medium reduces the time taken from collection to mass culturing by increasing the proliferation rate of undifferentiated mesenchymal stem cells derived from an adult tissue such as human marrow and adipose tissue, and also is capable of various differentiations into treating agents for bone-forming cells, for cartilage cells, or for fat cells.

Abstract: Disclosed are a biomaterial imparted with enhanced rubber properties through natural cross-linking between collagen and hyaluronic acid, a method of preparing the same, and a method of using the same, wherein the rubber-type biomaterial is prepared from collagen and hyaluronic acid at a ratio of 2:1 to 7:1 through natural cross-linking. Specifically, a novel material that exhibits rubber properties can be prepared from collagen and hyaluronic acid at an optimal mixing ratio taking into consideration the molecular structural properties thereof under natural cross-linking conditions, rather than chemical or physical cross-linkage, thereby remarkably improving the quality and reliability of products, ultimately fulfilling various needs of consumers to thus increase marketability.

Abstract: The present invention relates to a tissue sealant in which collagen and fibrin are mixed and to a method for preparing same. To this end, the method of the present invention comprises the steps of: mixing a first material using fibrinogen and aprotinin; mixing a second material using thrombin, calcium chloride, and collagen; and preparing a third material by mixing the first material and the second material. The tissue sealant prepared by the method may supplement weaknesses, i.e. strength and degradability, of the fibrin sealant which is currently available in the commercial marketplace. Further, the tissue sealant of the present invention is cytophilic and activates blood platelets contained in blood so as to induce tissue regeneration. Thus, quality and reliability of products can be significantly improved so as to satisfy various needs of consumers who are users, thereby presenting good image.

Abstract: The present invention relates to a composition for repairing cartilage tissue, to a method for producing same, and to the use thereof. The present invention provides a composition for repairing cartilage tissue, which is obtained by mixing collagen and hyaluronic acid using a two-way syringe or a mixer, wherein the collagen has a diluted concentration of 5-60 mg/mL excepting water or a physiological phosphate buffer solution, and the hyaluronic acid has a diluted concentration of 5-20 mg/mL excepting water or a physiological phosphate buffer solution.

Abstract: The memory device may include a first determination unit for determining whether entry into a DPD mode is to be made by interpreting signals received from a first processor, and generating and outputting a corresponding first DPD entry signal; a second determination unit for determining whether entry into the DPD mode is to be made by interpreting signals received from a second processor, and generating and outputting a corresponding second DPD entry signal; and a DPD determination unit for performing control for operation in the DPD mode only when the first DPD entry signal and the second DPD entry signal are respectively received from the first determination unit and the second determination unit. In accordance with the present invention, a single piece of memory operates in the DPD mode even when a plurality of processors shares the memory, so that power consumption can be minimized.
