Abstract: A content evaluation apparatus and a content evaluation method that can distribute contents that a user potentially needs without any omissions. A history class separation unit generates a separation plane for separating in a separation plane a characteristic vector of a selected content and characteristic vectors of non-selected contents stored in a browsing history table. A user characteristic vector calculation unit generates a user characteristic vector based on an orthogonal vector perpendicular to the separation plane thus generated and stores the user characteristic vector in a user characteristic vector management table. Subsequently, when a recommendation request receiving unit receives a recommendation request, a content evaluation unit evaluates the contents based on the stored user characteristic vector.

Abstract: A recommendation information generation apparatus and a recommendation information generation method that can select a similar user appropriately even if the amount of history information is small. In an information distribution server, a user characteristic vector calculation unit calculates a user characteristic vector of each of users, and a similar user calculation unit calculates the degree of similarity between the users based on the calculated user characteristic vector of each of the users. The similar user calculation unit then selects a similar user who is similar to a first user based on the calculated degree of similarity. A relevance evaluation unit generates recommendation information for the first user based on the characteristic vector of the selected similar user.

Abstract: A data receiving terminal (20) has a broadcast wave receiving function and a communication wave sending/receiving function. A communication control unit (210) receives data from a data distribution server (10) by using the broadcast wave receiving function. When having determined that there is a defect portion, a determination unit (220) determines whether or not to repair the defect portion according to at least one of a communication status between the data receiving terminal (20) and the data distribution server (10) and a data relevant status related to the data. When the determination unit (220) determines that the defect portion should be repaired, the communication control unit (210) requests the data distribution server (10) to resend the defect portion by using the communication wave sending/receiving function and receives the defect portion sent from the data distribution server (10) according to the request for resending by using the communication wave sending/receiving function.

Abstract: A data backup system includes a mobile device, a data storing apparatus for backup-saving user data used in the mobile device, and a user management apparatus for managing user information about a user using the mobile device, where the device and apparatuses communicate with each other. When the mobile device is a replacement for an old mobile device, the user management apparatus stores and manages a device ID of the mobile device in association with an old device ID of the old mobile device and personal identification information of a user using the mobile device and who has used the old mobile device. When downloading old user data previously used in the old mobile device from the data storing apparatus, the mobile device creates and transmits a user data acquiring request message with an old device user data acquiring request flag activated to the data storing apparatus.

Abstract: The high-strength non-combustible magnesium alloy is obtained by adding at least one supplementary additive selected from among carbon (C), molybdenum (Mo), niobium (Nb), silicon (Si), tungsten (W), alumina (Al2O3), magnesium silicide (Mg2Si) and silicon carbide (SiC) to small chip-like blocks of a non-combustible magnesium alloy resulting from adding 0.5 to 5.0% by mass of calcium to a magnesium alloy to produce a crushed product, and subjecting the same to forming, sintering and plastic working. The high-strength non-combustible magnesium alloy exhibits excellent joining ability, and can therefore enhance weldability when used in a filler metal.
