Abstract: A method, terminal and server for providing personalized food information for food safety are disclosed herein. The server includes a communication unit, and a processing unit. The communication unit receives a request for knowledge information related to the intake of a food of a user from a terminal and to send notification data to the terminal. The request includes the food identifier of the food and the personal information of the user. The processing unit generates the notification data, including the knowledge information, using food information, indicated by the food identifier, and the personal information.

Abstract: A wireless LAN distribution system, forwarding data received from a correspondent node to a station connected to an access point, includes: a location management server (LMS) for storing and managing a mapping table as an information table storing IP addresses of stations and physical access control addresses of the access points having the stations located therein, and causing the access points to perform an IP address check for the stations located in their area; an edge router for forwarding the data to the LMS using the physical access control address of the mapping table; and an access point for checking the physical access control address of the access point and the IP address of the destination station, and forwarding the data from the correspondent node.

Abstract: The backlight for a flat display device including a light source, a light guide plate and a surface hologram is provided. The light guide plate is installed at one side of the light source, and light from the light source travels in the light guide plate while being totally reflected. The surface hologram is formed on at least one surface of the light guide plate. The surface hologram has a pattern of a predetermined grating interval and a predetermined grating depth in order to diffract light at a predetermined angle toward the light guide plate.
