Abstract: Provided is a method and system for measuring traffic quality in distribution using test mail into which a radio frequency identity tag is inserted. The system accepts at least one test distribution piece including a tag, and collects information of test distribution by sensing a tag included with the test distribution piece at measuring points for measuring a time from acceptance to delivery of a general distribution piece. The system generates a processing rate and a delivery rate of distribution based on information of the test distribution pieces collected from the measuring points.

Abstract: The present invention relates to a multi-functional material emitting far-infrared ray in an aqueous phase which comprises extracts from the shells of shellfishes of and minerals, and to a deodorant containing the same. The material according to the present invention is prepared by treating the shells of shellfishes and minerals with an alkaline solution, treating the resulting solution with various inorganic materials, and then passing the solution thus obtained through magnetic materials. This far-infrared ray emitted material in an aqueous phase can be used in various industrial purposes since it is eco-philic, odorless, colourless and non-toxic and reveals multi-functionality. The deodorant prepared therefrom shows excellent deodorizing capability against the basic and acidic offensive smelling agents.

Abstract: Disclosed is a method for producing anti-E. coli O157 antibodies. Anti-E. coli O157:H7 antibodies are produced in egg-laying hens and isolated from the eggs. E. coli O157:H7 is cultured in a brain heart infusion broth and killed by the treatment with hot water for 5-10 min. After being collected by centrifugation, the dead bacteria is homogenized. Serving as an antigenic material, the bacterial homogenate is injected into egg-laying hens to induce antibodies against E. coli O157:H7 in the eggs. The induced antibodies are isolated from the yolk of the eggs and the eggs containing the antibodies against E. coli O157:H7 can be utilized, in their entirety, for foods. Alternatively, the yolks are separated from the eggs and freeze-dried. The resulting dried egg component can be applied to processed foodstuffs, alone or in combination with whole eggs. Since the antibodies against E. coli O157:H7 are contained in frozen eggs, it is very convenient to store the antibodies.
