Abstract: Disclosed is a display apparatus including: a display; an input comprising circuitry configured to receive a key moving command for moving between keys of an on-screen keyboard displayed on the display and a key-group selecting command for selecting a key group of the on-screen keyboard; and a processor configured to control a user interface (UI) of the on-screen keyboard, the keyboard comprising a first key group including keys=corresponding to a plurality of letters and a second key group including keys=corresponding to a plurality of functions, to be displayed on the display, to control an input marker moving between first keys of the first key group in response to the key moving command and at least one dummy marker moving between second keys of the first key group to be displayed if the first key group is selected by the key-group selecting command, to control an input of the first key to be made if a first key corresponding to the input marker is selected, to control a function marker moving between key

Abstract: The present invention relates to a light-emitting diode having enhanced liability. More particularly, a light-emitting diode has enhanced liability in a high-temperature and/or high humidity environment as well as in a room-temperature environment and can have decrease in light-emitting characteristics prevented. In addition, the present invention relates to a light-emitting diode comprising a structure which enables enhancing of light reflection and having enhanced light extraction efficiency by means of light reflection through the structure.

Abstract: Disclosed herein are an N-terminal modified PEG-TRAIL conjugates and methods of making and using thereof. The PEG-TAIL conjugates have bioactivity that is substantially similar to that of native TRAIL coupled with an extended in vivo half-life and enhanced stability. The disclosed PEG-TRAIL conjugates exhibit significantly reduced hepatotoxicity when compared to that of non-PEGylated trimeric TRAIL. The disclosed methods of making the PEG-TRAIL conjugates provide a homogeneous, highly pure, form of N-terminal modified PEG-TRAIL. Compared to native TRAIL, the PEG-TRAIL conjugates exhibits high solubility and solution stability. The PEG-TRAIL conjugates are useful in preventing and treating proliferative or autoimmune diseases.

Abstract: The present invention relates to a visible light-responsive photocatalyst with an excellent removal efficiency of environmental contaminants, and a method of preparing the same. According to the present invention, the TiO2 surface having an increased visible light absorbance due to nitrogen-doping has been modified into a hydrophilic surface using polydimethylsiloxane (PDMS), i.e., a silicon-carbon precursor, and thereby significantly improved the removal efficiency of environmental contaminants under visible light. Additionally, the photocatalyst of the present invention for removing environmental contaminants is applicable to environment-friendly fields such as removal of volatile organic compounds, air purification, wastewater treatment and sterilization, and enables to remove contaminants by being attached to the surfaces of external walls of buildings, construction materials, glass windows, sound-absorbing walls, road facilities, signboards, etc., while preventing damages by sunlight.
