Abstract: A near field communication (NFC) antenna includes a first antenna electrode and a second antenna electrode, and a loop coil. The first and second antenna electrodes are formed on a first surface of a substrate. The loop coil is formed on the first surface of the substrate, is directly coupled between the first antenna electrode and the second antenna electrode, and includes a first plurality of turns. The first antenna electrode is located inside each of the plurality of turns of the loop coil, and the second antenna electrode is located outside each of the plurality of turns of the loop coil. An imaginary line passing through the first antenna electrode and the second antenna electrode is parallel to one of edges of the substrate. Each of the first plurality of turns of the loop coil does not overlap each other.

Abstract: Disclosed is an attenuation method of an influenza virus, that is, a reassortant virus and a preparation method thereof. The disclosed reassortant virus has, in a ratio of 6:2, genes encoding a recombinant non-toxic protein and a wild type non-toxic protein, and genes encoding toxic proteins, HA (hemagglutinin) and NA (neuraminidase), of an influenza virus, the recombinant non-toxic protein consisting of a substituted caspase recognition sequence without a change of a protein size within the wild type non-toxic protein of the influenza virus. The disclosed attenuated influenza virus shows a high attenuation without a reduction of productivity in a fertilized egg. Accordingly, the method can be used as an economically efficient live vaccine preparation method which has both safety and efficiency and can use a fertilized egg as a production system.

Abstract: The object of this invention is to provide a milling cutter which includes a cutting insert (120), which has a hexahedral shape and is provided with first and second cutting blade parts on opposite ends thereof, and a cutter body (110) provided with a plurality of insert seats (112) which the cutting insert (120) is seated in and fastened to in either of two directions. The cutting insert (120) is fastened to the associated insert seat (112) in a selected direction, thus all corner blades or main blades, provided on the first and second cutting blade parts of the cutting insert, can be used for machining workpieces. Therefore, the present invention extends the lifetime of the cutting insert (120).

Abstract: A rear impact shock absorbing structure for a fuel cell vehicle. The shock absorbing structure appropriately absorbs shocks in the event of a rear impact, thus preventing hydrogen storage tanks from colliding with a chassis cross member arranged between the hydrogen storage tanks, therefore preventing the hydrogen storage tanks from being broken or damaged. The shock absorbing structure includes a front tank support for supporting a hydrogen storage tank provided in front of a chassis cross member. A rear tank support supports a hydrogen storage tank provided in back of the chassis cross member. Further, a shock absorbing member connects the front and rear tank supports to each other, and is deformed when shocks are applied to the front and rear tank supports.
