Abstract: Provided is a pyrolysis furnace having a gas flowing path controller with an improved structure. The pyrolysis furnace includes: a silicon substrate; a main body of the pyrolysis furnace; a heating unit that is formed around the main body and controls the temperature of the main body; at least one gas supplying tube through which a gas flows into the main body; and a gas flowing path controller that is installed inside the main body and controls the flow of the gas. As a result, controlling and manufacturing of small-sized nanoparticles with excellent characteristics is possible.

Abstract: A method of providing a user interface (UI) and a multimedia device on a touch screen, the method including: detecting a first form of touch or a second form of touch on a menu or on a background of the touch screen; and performing a first operation if the first form of touch is detected and a second operation if the second form of touch is detected. Accordingly, the user can select a diverse range of options from menus with greater ease and convenience.

Abstract: A graphical user interface (GUI) and a multimedia device using the same. The method for providing a graphical user interface (GUI) includes displaying first GUI items selectable by a user on a screen, removing from the screen at least one of the first GUI items displayed on the screen by zooming in or zooming out, and additionally displaying on the screen at least one second GUI item that was not displayed on the screen by zooming in or zooming out. Accordingly, a GUI to provide more convenient manipulation and better visual effect on a small screen can be provided.

Abstract: Provided is a nonvolatile memory device and a method of manufacturing the same. The nonvolatile memory device includes a semiconductor substrate on which a source, a drain, and a channel region are formed, a tunneling oxide film formed on the channel region, a floating gate formed of a fullerene material on the tunneling oxide, a blocking oxide film formed on the floating gate, and a gate electrode formed on the blocking oxide film.

Abstract: A method for providing a menu and a multimedia device using the method are provided. The method for providing a menu includes converting a menu set including at least one icon displayed on a touch screen into a manipulation set including at least one manipulation icon used to input a command relating to the use of content. Therefore, the method provides for a more easily manipulated menu, which is displayed with superior visual effect on a screen that is relatively small in size by using the menu set capable of conversion into the manipulation set.

Abstract: The nanoparticle structure includes: a substrate; and nanoparticles formed on the substrate, wherein the nanoparticles include silicide. The method of manufacturing the nanoparticle structure includes: forming an Si source layer to a predetermined thickness; forming nanoparticles using a predetermined metal and silicon; depositing the nanoparticles on the Si source layer; and growing the nanoparticles to form silicide. Nanoparticles having a desired size can be easily obtained by adjusting the thickness of the silicon source layer.
