Abstract: Provided is a method for recovering and reusing an active material from a positive electrode scrap.

Abstract: A display device includes a voltage wiring pattern in a non-display area and connected to a display area, and between a pad area and the voltage wiring pattern, a metal wiring pattern in the non-display area and connecting the pad area to the voltage wiring pattern, and a sealing member between the pad area and the voltage wiring pattern, and coupling the display panel to an encapsulation substrate. The metal wiring pattern including a lead-in portion connected to the pad area, an overlapping portion overlapping the sealing member, and a connection portion connecting the overlapping portion to the voltage wiring pattern. The overlapping portion includes a first portion corresponding to the lead-in portion, a second portion corresponding to the connection portion, and a third portion extending from the second portion in a direction away from the first portion.

Abstract: Provided is a two-liquid type hemostatic composition that may be used adjunctively during a wide range of bleeding events and surgeries, and a method for preparing the same. The two-liquid type hemostatic composition does not contain blood products, comprises a first solution containing chitosan and a second solution containing a glucose or cellulose compound, may be easily applied in a liquid form to a wound or surgical bleeding site of the human body, and may help hemostasis and recovery by immediately forming a hydrogel at the bleeding area.

Abstract: An organic light emitting display device including a display panel including a plurality of scan lines, first through (M)th data lines crossing the scan lines, and a plurality of pixels, where M is an integer greater than 1, a scan driver configured to provide scan signals to the pixels through the plurality of scan lines, a data driver configured to provide data signals to the pixels through the first through (M)th data lines, and a porch data generator configured to generate porch data based on an average value of at least a portion of frame data, and to provide the porch data to the data driver, wherein the data driver is configured to generate the data signals based on the porch data during a porch period, and to generate the data signals based on the frame data during an active period.

Abstract: The present invention relates to a method for preparing a contact lens-shaped amniotic dressing and a contact lens-shaped amniotic dressing prepared therefrom for treating ocular surface diseases, which does not require the use of sutures or an adhesion material. The inventive contact lens-shaped amniotic dressing is capable of solving the problems associated with suturing an amniotic membrane, e.g., highly delicate surgical techniques of suturing, long surgery time, stitch abscess, granuloma formation, tissue necrosis, and discomfort of patients; and the problems associated with the use of a support, e.g., the elimination of the support by eye blinking, breaking of the support, and discomfort.

Abstract: The present invention relates to a biological implantation material and method of preparing the same, which comprises the steps of: (i) treating a tissue derived from animal or human with alcohol; (ii) contacting the said tissue with an enzyme selected from the group consisting of dispase, DNAse, RNAse and pepsin in a solvent; (iii) treating the tissue obtained in step (ii) with alkaline solution; and (iv) treating the tissue obtained in step (iii) with acid solution.

Abstract: The present invention relates to a dermal substitute comprising the biodegradable polymer such as collagen and the biomaterial such as amnion, the preparation method and the use thereof. Specifically, the present invention provides with an amnion-collagen sponge complex structure prepared by attaching, inserting or incorporating an amnion obtained from placenta to/in collagen. Inventive dermal substitute can be applied to surgery and wound requiring skin graft, for example, severe burns such as second-degree burn, without rejection by immune system. Further, inventive dermal substitute with amnion instead of silicone membrane has several advantages, such as better biocompatibility, anti-inflammatory activity and promoting activity of wound healing and commercial utilization as basement membrane. Also, inventive complex structure can be used as the basic matrix of bio-artificial skin for culturing cells and the biodegradable basic matrix for preparing artificial organs.
