Abstract: An apparatus and a method for assisting traveling of a vehicle are provided. The apparatus includes: a sensing unit; a processor configured to generate a traveling route available to the vehicle by using information acquired through the sensing unit while the vehicle is traveling; and a memory storing information about the generated available traveling route.

Abstract: An electronic apparatus which is capable of being worn on a user's body is provided. The electronic apparatus includes first and second wearing units configured to connect to each other, the first wearing device including a first measurer configured to measure the user's body, and a first communicator configured to communicate with the second wearing device, and the second wearing device including a second measurer configured to measure a user's body, and a second communicator configured to communicate with the first wearing device, and a at least one main processor configured to process a first measurement signal generated by using the first measurer while the first and second wearing devices are connected to each other, and to process a second measurement signal measured and generated by the second measurer while the first and second wearing devices are either connected to each other or disconnected from each other.

Abstract: A virtual environment system and a method of operating the same are provided. The virtual environment system includes a virtual operating system (OS) unit to operate a virtual OS installed in a mobile storage medium in a host OS installed in a host computer, to attach a virtual resource included in the virtual OS to the host OS, and to perform arbitration so that a virtual process operated in the virtual OS uses the virtual resource. The system includes a user interface unit to provide a virtual desktop screen to allow a user to use the virtual process in the virtual environment provided by the virtual OS.

Abstract: A method of managing data of a file system using a database management system is provided. According to the method, the metadata of the file system is managed using a database management system (DBMS), but writing data to or reading data from a disk is directly performed by the file system according to the method directly performed not through other file systems or DBMSs. In this way, stable transactions are guaranteed for a user, and the user can design a disk allocation algorithm optimized with respect to a multimedia environment.

Abstract: A method and apparatus for inputting and outputting data by using a virtualization technique are provided. The method includes generating a virtual operating system (OS) for the external device, which is connected to a host, based on OS information stored in the external device, setting a partial area of a storage of the host as virtual storage for the external device, and storing the data in the virtual storage or a memory of the external device in response to a request for inputting and outputting the data from the virtual OS.
