Abstract: A digital device and a UI control method thereof are provided. A user interface (UI) generator generates a UI, a controller controls the UI generator to generate a UI which includes a menu area to display a list of contents for a sub-category from one or more sub-categories and a scroll bar to display information on the respective sub-categories, and a display unit displays the generated UI.

Abstract: A method of manufacturing a micro electro-mechanical component having a three-dimensional structure includes preparing a conductive substrate, selectively insulating or removing the conductive substrate to form a functional structure for performing a desired electro-mechanical function, forming a plated structure serving as an electrical connection portion on at least one surface of the functional structure, and mounting the functional structure on a circuit substrate so that the electrical connection portion is connected to a circuit pattern of the circuit substrate.

Abstract: A method for displaying widget windows is provided, including generating a widget display screen including at least one widget window, determining if a display area of the at least one widget window satisfies a preset threshold condition, and adding a new widget display screen including a new widget window if the threshold condition is satisfied. Accordingly, services can be provided through widget windows without preventing the viewer from viewing the TV, thereby enhancing user convenience.

Abstract: A display apparatus for displaying a widget window and method thereof are provided. The display apparatus includes a generating unit which generates at least one widget window, a display unit which displays the least one widget window generated by the generating unit on a screen, and a control unit which changes a display pattern of the widget window, if a preset event occurs. Accordingly, the display patterns of widget windows are changed according to a user's preference, making it possible to increase the user's convenience.

Abstract: The present invention relates to a method for preparation of the supersaturated calcium and phosphate ions solution and a method for preparation of the thin film of calcium phosphate crystal on solid surface by using the said solution. Particularly, the lowered temperature and/or the use of suitable buffer system inhibit the nucleation of calcium phosphate in aqueous solution, and thereby highly supersaturated calcium and phosphate ions solution can be prepared. And the thin film of calcium phosphate crystal on solid surface can be prepared with rapidity and good quality of high reactivity and low crystallinity by using the said solution. Also the thin film of calcium phosphate crystal prepared according to the present invention has biocompatibility and can be applied as biomaterials.
