A bar type portable wireless terminal includes a lower body installed at its one side surface with a camera lens unit, and at the other surface an image reproduction device is adapted to output images captured by the camera lens unit, and an upper body coupled to an upper end of the lower body so that it is rotatable in a twisting direction relative to a rotation axis extending in a longitudinal direction of the lower body, the upper body being installed at its front surface with a display device adapted to enable the output of the images captured by the camera lens unit. The portable wireless terminal can be used as a digital image device and functions as portable phone, PDA and so on.

The present invention provides a dual journaling storing method and a storage medium thereof, in which data are stored toward a central portion of a storage space of the storage medium from start and end locations when a flash memory or the like is used as a storage medium for storing/managing/processing data. One data is stored from a start location of the storage medium based an the journaling method, and another data is stored from an end location of the storage medium toward the start location.

A portable telephone with an exchangeable data input apparatus is provided. The portable telephone includes a bar-type main housing; a holding housing having first and second hinges positioned to face each other, to be protrusive, and to be symmetrical with each other and a sliding surface with a predetermined radius of curvature to be separated from the first and second hinges and attached to and detached from the main housing; and an exchangeable housing having bar-type first and second rotational sub housings with each one side connected to the first and second hinges so that the first and second rotational sub housings are hidden in the main housing when folded in and are in the form of wings protruding from both sides of the main housing when they are unfolded.

Provided are a network node and a method of performing discovery, which may stably perform discovery without delay or crash of a network at the time of initial discovery in a large-scale network. The network node operated in a distributed network includes a discovery performing unit that determines a discovery back-off time that is a transmission wait time of a discovery message based on levels of priority of the network node, and a communication unit that transmits the discovery message using the discovery back-off time.
