Provided is a method of manufacturing a high-purity lithium phosphate by utilizing a lithium waste liquid of a wasted battery. Lithium phosphate is manufactured and refined by using a minimized amount of sodium hydroxide and by using phosphate, lithium hydroxide, and an optimized pH condition, so that it is possible to manufacture high-purity lithium phosphate from which fine impurities which cannot be removed by cleaning are effective removed. A waste water treatment process of processing waste water as to be immediately discharged is integrated, so that the method is very efficient and environment-friendly. Therefore, since the high-purity lithium phosphate can be manufactured by utilizing a lithium waste liquid discarded in a wasted battery recycling process, the method has an effect in that the method is applied to a wasted battery recycling industry to prevent environmental pollution and facilitate recycling resources.


The present invention relates to an apparatus for manufacturing fiber-reinforced concrete through shooting after inserting bubbles into normal concrete and a method for manufacturing the same, which: form fiber-mixed concrete in which the bubbles, fiber-mixed materials, and silica fume are mixed in the normal concrete or form the fiber-mixed concrete in which aggregates, water, and the bubbles are put into and mixed with a mixture, in which cement, the fiber-mixed materials, and silica fume are mixed; and then shoots the fiber-reinforced concrete in which excessive air included in the fiber-mixed concrete is reduced by spraying the fiber-mixed concrete with the high-pressure air when the fiber-mixed concrete is discharged, and of which a slump, drastically increased due to the large amount of bubbles, is reduced to a range of the slump of the normal concrete, thereby improving the production capacity of the fiber-reinforced concrete and shortening operating time.


Disclosed is a drug delivery carrier for sustained release of medicinal protein. The drug delivery carrier has an effect of efficiently loading medicinal proteins that are positively charged at a pH value of an isoelectric point or less of the medicinal proteins, based on electrostatic attraction. In addition, the drug delivery carrier releases medicinal proteins under human physiological conditions (pH 7.4, 37 C.) based on electrostatic repulsion and more specifically, has an effect of sustainedly releasing medicinal proteins for a long time between heat-sensitive polymer layers condensed due to body temperature.

Disclosed is a composition for the prevention or treatment of vascular leakage-induced diseases and diabetic retinopathy, comprising C-peptide. Found to prevent extravascular leakage by inhibiting VEGF-induced disassembly of VE-cadherin, C-peptide can be applied to the prevention or treatment of various diabetic complications accompanied by vascular leakage.


Disclosed are a negative active material for a rechargeable lithium battery including a spherically-shaped natural graphite-modified composite particle including: a spherically-shaped natural graphite particle where flake-shaped natural graphite fragments build up and assemble into a cabbage or random shape; and amorphous or semi-crystalline carbon, wherein an open gap between the flake-shaped natural graphite fragments is positioned on a surface part or inside the spherically-shaped natural graphite particle, the amorphous or semi-crystalline carbon is coated on the surface of the spherically-shaped natural graphite particle, and the amorphous or semi-crystalline carbon is present in the open gap, and thereby the open gap positioned on the surface part and inside the spherically-shaped natural graphite particle is maintained, a method of preparing the same, and a rechargeable lithium battery including the same.


Provided is an image transmission apparatus in digital TV broadcasting, including: a first converter which converts added data, which are to be inserted into an image, into a pixel block; a border extender which adds an extended border area to an image area to extend the image in video data and inserts the converted added data into the extended border area; a video encoder which encodes the video data into which the border extender inserts the added data; a video decoder which decodes the video data encoded by the video encoder; and a second converter which converts the added data which are inserted as a pixel block in the video data decoded by the video decoder into original data. Accordingly, in digital TV broadcasting such as HD TV an UDTV, the added data are inserted into a hidden area, so that it is possible to transmit various types of information including contents and copyright without a deterioration in image quality.


The present invention relates to a method for constructing a continuously reinforced concrete pavement using foam shotcrete by: positioning continuous reinforcement bars on a base layer where a concrete pavement is constructed; producing normal concrete having a compressive strength of 21-30 MPa from a batch plant and transporting same to a construction site; and shooting a normal strength concrete, which has been produced by mixing, with a mixing part, fly ash or fine slag powder or a low-grade mixed material produced by mixing the fly and the fine slag powder in a state in which fluidity has been increased by mixing in 20-40% of air bubbles with respect to volume, or shooting a high-performance concrete, which has been produced by mixing, with the mixing part, one or a mixture of two or more of silica fume, meta-kaolin, latex, polymers, and a coloring material.
