Abstract: The present invention relates to a novel lappaconitine derivative and a pharmaceutically acceptable salt thereof, a preparation method therefor, and a medical use thereof using osteogenesis-promoting activity. The lappaconitine derivative induces the differentiation of stem cells into preosteoblasts, and increases bone density when administered to an osteoporosis animal model, and induces osteogenesis, and thus can be effectively used for preventing, alleviating, or treating bone-related diseases such as osteoporosis.

Abstract: The present invention pertains to a novel lappaconitine derivative, a method for producing same, and a pharmaceutical use thereof using osteogenesis-promoting activity. The lappaconitine derivative induces the differentiation of stem cells into osteoblasts, increases bone mineral density when administered to animal models of osteoporosis, and induces bone formation in animal models of bone fracture, and thus can be advantageously used for preventing, ameliorating, or treating bone-related diseases such as osteoporosis, as well as treating non-disease fractures caused by physical trauma.

Abstract: This invention relates to a bipolar plate for a fuel cell having a controlled structure of carbon materials and a method of manufacturing the same, the method including obtaining a masterbatch by mixing a first carbon material powder having a size ranging from 0.1 to 200 ?m with a polymer resin, forming a masterbatch powder by crushing the masterbatch, preparing a conductive composition by mixing the masterbatch powder with a second carbon material powder having a size ranging from 300 ?m to 1 mm, and manufacturing a bipolar plate by subjecting the conductive composition to compression molding. Thereby, carbon materials in a powder phase having different sizes can be uniformly dispersed via a masterbatch to thus shorten a conductive path, thereby decreasing electrical resistivity, and furthermore, dispersion in the polymer resin can be improved, thereby increasing flexural strength.

Abstract: The present invention relates to a method of manufacturing a multi-structural high-heat-dissipation part having the controlled packing density of a carbon material and to a multi-structural high-heat-dissipation part manufactured thereby, the method including preparing a mixture by mixing a binder pitch with a carbon material including a first carbon material powder and a second carbon material powder having a smaller diameter than the diameter of the first carbon material powder, forming a compact from the mixture using a hot-forming process, and producing a graphitized pitch/carbon material compact by subjecting the compact to graphitization through heat treatment and cooling. Thereby, the packing density of the carbon material can be improved through bimodal distribution using pieces of carbon material having different diameters, thus increasing thermal conductivity in in-plane and through-plane directions and strength.

Abstract: An input parameter monitoring apparatus is disclosed wherein input parameters for ion implantation can be stored in a database during an ion implantation process, thereby allowing a user to monitor the operational history from a remote location. A method of monitoring input parameters created during an ion implantation process in a semiconductor fabricating device includes collecting log data generated by a plurality of ion implantation devices, listing the collected log data in a database in chronological order and updating the database substantially contemporaneously during said process. The log data can be processed to enable textual or graphical display. A LAN connects a local computer connected via input ports to plural ion-imp devices and a remote computer, thereby enabling remote computer monitoring of the operational process and possibly interaction.
