Abstract:
The present invention provides a method for preparing a Broussonetia kazinoki extract, comprising the following steps: solvent extracting Broussonetia kazinoki; isolating the Broussonetia kazinoki extract, extracted in the previous step; and crystallizing the Broussonetia kazinoki extract isolated in the previous step. It is possible to prepare a Broussonetia kazinoki extract having a remarkable skin whitening effect and excellent stability through the method for preparing a Broussonetia kazinoki extract.
Abstract:
The present disclosure provides a method of preparing highly pure lithium carbonate from brine. The method includes adding an adsorbent to the brine, from which the magnesium ions Mg2+ have been removed, to adsorb lithium ions Li+ to the adsorbent, followed by providing the adsorbent having the lithium ions Li+ adsorbed thereto to a strong acid solution to desorb the lithium ions Li+ from the adsorbent; enriching the strong acid solution in which the lithium ions Li+ are desorbed from the adsorbent; and obtaining lithium carbonate Li2CO3 through chemical reaction between the lithium ions Li+ in the enriched solution and a carbonate precursor.
Abstract:
A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include one or more BaseURL elements. Uniform Resource Locators (URLs) of segments forming media may be generated based on the BaseURL elements. Additionally, a URL of a segment may be generated by mapping a BaseURL element among the BaseURL elements to a sourceURL attribute of the segment. Segments indicated by generated URLs may be identical to each other.
Abstract:
The present invention relates to a theanine derivative, a preparation method thereof, and a use thereof for anti-acne treatment, having a selective inhibitory effect on Propionibacterium acnes in the skin.
Abstract:
The present invention relates to a kit for screening for skin-activating substances, and to a method for screening for skin-activating substances using same. More particularly, the present invention relates to a kit for screening for skin-activating substances and to a method for screening for skin-activating substances using same, in which candidates for inducing the expression of the klotho gene are separated from skin cells by the screening kit comprising the klotho gene, also known as the anti-aging gene, and the separated candidates are refined, thus screening for skin-activating substances such as moisturizing, anti-aging, or whitening substances.
Abstract:
The present invention relates to a method for fermenting natural products with salt and fermented extracts prepared thereby. The method comprises: adding a predetermined amount of salt to at least one of natural products, including medicinal herbs and cereals; naturally fermenting the salted material; and extracting the fermented salted material with a solvent. Accordingly, the method can prevent the growth of various bacteria, including putrefactive bacteria, E. coli and anaerobic bacteria, which are harmful to the human body, in the natural product, and it also can prevent the generation of bed smells in the natural product. The fermented extract prepared by the method has fewer side effects and is safer than fermented extracts prepared by conventional fermentation methods.
Abstract:
Disclosed are a positive photosensitive resin composition that includes (A) an alkali soluble resin including a polybenzoxazole precursor, a polyimide precursor, or a combination thereof, (B) a photosensitive diazoquinone compound, (C) a phenol compound, (D) at least one organic dye having an absorption wavelength of about 400 nm to about 700 nm, and (E) a solvent, wherein the organic dye (D) is included in an amount of about 1 to about 40 parts by weight based on about 100 parts by weight of the alkali soluble resin (A), and a photosensitive resin layer and a display device using the same.
