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 is a nuclear power plant container structure, the structure comprising: a hollow structure having a plurality of cells, each having a hollow portion therein, which are partitioned by cell walls and air-ranged in a three-dimensional pattern so as to form an empty space for sealing and storing the radioactive waste therein; a cladding for surrounding the outside of the hollow structure; and a filler selectively filled into the hollow portions of the cells for suppressing nuclear reactions of the radioactive waste or blocking radioactivity radiated from the radioactive waste.

Abstract: A hollow-core structure including: an inner mold that has a hollow cylindrical shell shape; an outer mold that has a hollow cylindrical shell shape to correspond to the inner mold, and in which the inner mold is disposed to be separated; and a filling member that is filled in a separation space between the inner mold and the outer mold.

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: Disclosed are a structure for construction, which includes a hollow structure having a plurality of cells provided therein with hollows, arranged in a set three-dimension pattern, and partitioned by cell walls, and a cover enclosing the outside of the hollow structure, and a method of manufacturing the same. In this way, because the plurality of hollow cells of the hollow structure are partitioned by the cell walls and provided therein with the hollows, the overall weight can be reduced, and the rigidity and strength can be maintained at an adequate level despite the reduced weight. Also, due to the cells installed in the three-dimensional pattern, the growth of cracks or damage caused by impacts can be confined to local areas. Furthermore, since the weight is reduced, distribution and transportation costs can be reduced.
