  • Patent number: 9687545
    Abstract: Disclosed are a nonspecific immunostimulant composition, a preparation method thereof, and uses thereof. The composition includes 150 to 300 wt. parts of sodium silicate, 2˜8 wt. parts of sodium thiosulfate, 0.5˜2 wt. parts of sodium carbonate, 0.5˜2 wt. parts of potassium chloride, 200˜400 wt. parts of white sugar, and 300˜400 wt. parts of water, based on 100 wt. parts of potassium carbonate. The composition exhibits excellent defense against the mortality caused by AIV H5N1, thus improving the survival of infected animals. As a supplement of a formulated feed mixture for farmed aquatic organisms, the composition provides excellent immunostimulation and disease resistance so as to decrease the mass mortality of aquatic organisms and to increase productivity. Particularly, when raised with a food in mixture with the composition, livestock and farmed aquatic organisms are immunologically improved so that they can endure and are protected against epidemic diseases caused by viruses and bacteria.

  • Publication number: 20130298064
    Abstract: A virtual keyboard, an apparatus, and method using the virtual keyboard provide supplementary character input. The virtual keyboard includes basic character keys which correspond to basic characters of a basic character set corresponding to a currently set input language, respectively, and at least one character function keys. If the character function key is input, basic character keys corresponding to basic characters to which supplementary characters of at least one supplementary character sets corresponding to the input language are mapped respectively are switched to supplementary character keys of a supplementary character set which is set to correspond to the input character function key. Virtual key stamps of the corresponding basic characters are displayed on the basic character keys. Virtual key stamps of the corresponding supplementary characters are displayed on the supplementary character keys.
