Abstract: Proposed are a device for supporting height growth by using a pulsed micro-electromagnetic field, and a method for driving the device. According to an embodiment, the device may include an antenna band part including a first antenna and a second antenna which are provided inside a covering part that is configured to surround a joint and which are configured to generate a micro-magnetic field at the joint in a contactless manner, and may include a control unit configured to generate the micro-magnetic field by forming a high frequency voltage and providing the high frequency voltage to the antenna band part, the control unit being configured to adjust the formed high frequency voltage, on the basis of a sensing value of a micro-electromagnetic field sensed at the second antenna, such that a micro-magnetic field corresponding to a diameter of the joint is provided.

Abstract: The present invention relates to an apparatus and a method for managing content, such as pictures, with category information. In the method, when there is a picture to be stored, category information to be entered to the picture is identified. An application header including the category information is created. The picture including the application header is encoded and stored. Accordingly, easy and efficient picture management is achieved.
