Abstract:
The present invention relates to inorganic bone graft materials and a method for preparing the bone graft materials. Particularly, the present invention relates to a method for preparing bone graft materials comprises the following steps: collecting cancellous bones from an animal; removing lipids and organic materials from the cancellous bones using organic solvent, sodium hypochlorite and hydrogen peroxide; and sterilizing the cancellous bones wherefrom the lipids and the organic materials are removed. The bone graft materials prepared by the method of the present invention meet requirements for use in bone grafting, including biocompatibility, sterilization, osteoinductivity and osteoconductivity with free from immunogenecity and toxicity to tissue and are suitable for use in osteogenesis and have morphogenesis.
Abstract:
The present invention relates to an apparatus and a method for determining cracked eggs by driving vibrations without hitting eggs. The apparatus for determining cracked eggs comprises an integral type sensor and actuator which carries out applying a vibration to an egg in the state of contacting with the egg and detecting a vibration response signal corresponding to the vibration from the egg at the same time; a determination unit for determining whether or not the egg is cracked based on at least one of a resonance frequency and a quality factor of the vibration response signal detected from the integral type sensor and actuator; and a transport unit for moving the integral type sensor and actuator or the egg relatively to each other.
