Abstract: The present invention relates to an access management system to prevent spread of infectious diseases using hybrid location information. A management server (11) is connected to a store server (12) and a plurality of user terminals (13) through a network. The management server (11) includes a store DB (22) and a reference DB (25) including store information. The store DB (22) stores visitor information and access time of a store, and the reference DB (25) stores pre-measured data to determine an indoor location for each store. When a pre-designated and pre-equipped identification number is recognized by the user terminals (13), the user terminals (13) transmit the recognized identification number and user information to the management server (11). An access confirmation module (36) recognizes the user and the store, lists them in visitor DB (23), and transmits a check-in message to the user terminal. A location identification module (31) transmits data for indoor location identification stored in the reference DB (25) to the user terminal, and compares the data for indoor location identification sent from the user terminal with the information in the reference DB (25) so that the store that is identified is correct. If an indoor location identification module (32) of the user terminal (13) does not identify that the user is indoors, it is regarded as checked out and the management server (11) updates the visitor DB (23) to provide information of the user entering and leaving the store for allowing it manageable.

Abstract: The present invention relates to a far-infrared antibacterial radiation-type yarn having antibacterial and deodorizing functions, and to a fabric for clothing manufactured thereby. Conventionally, a natural mineral emitter has been used to emit far-infrared rays. This has the disadvantage that, when a crystal structure is not spherical, a cylinder and a nozzle of a fiber spinning machine are worn during melt spinning, so that fibers of a certain thickness cannot be obtained, and the production yield is greatly reduced. In addition, when a used antibacterial agent uses natural extracts, silver zeolite, silver powder, etc., there is disadvantages that antibacterial power is easily destroyed by heat, melt spinning is impossible, and the same has to be used for extremely limited fibers, especially because the same is colored. The present invention comprises a mixed composition of a polyester resin, an artificial synthetic far-infrared emitter, a silver-based inorganic antibacterial agent and a silicone oil. After putting this mixed composition into a hopper dryer, the same is extruded and cut into pellets. The pellets are put into a dehumidifier and dried, and then put into a spinning machine and spun. The spun yarn is bobbed and put into the stretching machine, and then the yarn is obtained by stretching. Thus, it is possible to solve the conventional problems.

Abstract: A separation membrane and an electrochemical device including the same according to the present invention have low internal resistance between the separation membrane and an electrode. The separation membrane includes heat resistant particles in a heat resistant coating layer, and the heat resistant particles are obtained by doping fluorine (F) on the surfaces of inorganic particles. When the temperature inside a battery increases during battery driving, the heat resistant characteristics of a separation membrane are improved by a heat absorption effect by a phase change of heat resistant particles. In addition, a decomposition reaction of lithium salts used as an electrolyte component is suppressed by fluorine atoms introduced into the heat-resistant particles. Accordingly, there is an effect that ionic conductivity and resistance characteristics are improved. Moreover, a separation membrane into which the heat resistant particles are introduced has excellent resistance properties, and oxidation safety with respect to electrolytes is high. Thus, the electrochemical stability of a cell is improved.
