Provided are a system and method for providing a document based on a personal network. The document providing system may include a community searching unit to search for a community associated with a first document prepared by a first user, a document registration unit to register the first document in the searched community, and to receive a second document, associated with the first document, registered by a second user included in the community, and a document providing unit to provide the second document associated with the first document. According to embodiments of the present invention, a response that the first user may desire may be provided by receiving a response, registered by the second user included in the community associated with the first user, with respect to the document prepared by the first user.

System and method for providing document based on personal network

A system and method for providing a search result based on a personal network are disclosed. The search result providing system may include a search term reception unit, a personal network extraction unit, and a search result providing unit which may receive a search term from a user. The personal network extraction unit may extract at least one of a personal network associated with the search term, and a personal network associated with the user. The search result providing unit may provide documents associated with the personal networks as a search result of the search term. A search result optimized for the user may be provided to the user by searching for information corresponding to the search term from communities joined by another user having similar interests to that of the user, or communities joined by the user, based on personal networks of the user.

A method of operating a flash memory device includes reading a first bit data by employing a first read voltage or a second read voltage higher than the first read voltage according to a program state of a first flag cell. The first flag cell is programmed when the first bit data is programmed into the MLC. A second bit data may be read by employing a third read voltage that is higher than the first read voltage or the second read voltage, or by employing the first read voltage and the third read voltage according to a program state of a second flag cell. The second flag cell is programmed when the second bit data is programmed into the MLC. Alternatively to reading the second bit data, the second bit data is fixed to a set data and the set data is output.

Method of operating a flash memory device

A system and method for playing a golf game. A user is allotted with an ability value for the golf game, and a plurality of available golf clubs are provided according to the user's ability value. A request ability value referred to when requesting to use a corresponding golf club and an application ability value applied when the golf club is used are allotted to each of the golf clubs. Only when the user's ability value satisfies the request ability value allotted to a golf club can the user use the golf club. Ability points that can adjust the user's ability value are allotted to the user according to a result of the golf game, so that the user can select from a wide range of golf clubs having various characteristics. Accordingly, the user can adjust the ability value which influences the percentage of winning the golf game using the ability points allotted according to the result of the golf game, thereby enhancing the fun of the golf game.
