摘要:
The present invention relates to a new use of lignan-type compounds or an extract of nutmeg or aril of nutmeg comprising the same. More particularly, the present invention relates to a composition for skin whitening comprising a lignan-type compound or an extract of nutmeg or aril of nutmeg comprising the same. Because the lignan compound represented by Chemical Formulas 1 to 3 or the extract of nutmeg or aril of nutmeg has superior skin whitening activity by inhibiting melanin production and tyrosinase activity, it can be used for the preparation of a cosmetic composition, food composition or pharmaceutical composition for skin whitening.
摘要:
The present invention relates to a method of preparing an ethylene-α-olefin-diene copolymer and an ethylene-α-olefin-diene copolymer prepared thereby, by using a transition metal compound based on a cyclopenta[b]fluorenyl group as a catalyst.
摘要:
A microorganism of the genus Corynebacterium having the ability to produce inosine in which the inosine catabolic pathway is blocked and that has a leaky adenine auxotrophic phenotype and further has a leaky guanine auxotrophic phenotype and a method of producing inosine, the method including culturing the microorganism of the genus Corynebacterium are disclosed.
摘要:
Provided is a pseudolipid complex mixture comprising a pseudoceramide and a stearic acid and an external skin application composition comprising the same. The complex mixture has improved phase stability and a structure similar to that of the stratum corneum which can retain water and other beneficial materials, and accordingly the composition comprising the same can be used as an external skin application composition having improved moisturization and barrier repair capabilities.
摘要:
The present invention relates to a new transition metal compound based on cyclopenta[b]fluorenyl group, a transition metal catalyst composition containing the same and having high catalytic activity for preparing an ethylene homopolymer or a copolymer of ethylene and one α-olefin, a method of preparing an ethylene homopolymer or a copolymer of ethylene and α-olefin using the same, and the prepared ethylene homopolymer or the copolymer of ethylene and α-olefin.

Disclosed are a backlight unit and a display apparatus using the same. The backlight unit includes a light guide plate including first and second grooves, and light source modules disposed within the second grooves. The first grooves are disposed on the upper surface of the light guide plate, and the second grooves are disposed on the lower surface of the light guide plate, and the first grooves are disposed between light sources of the light source module.
摘要:
A thin film transistor includes a substrate, a gate electrode on the substrate, a gate insulating layer covering the gate electrode, a first semiconductor layer and a second semiconductor layer overlapping the gate electrode on the gate insulating layer and separated from each other, a first source electrode and a first drain electrode on the first semiconductor layer and on opposite sides of the gate electrode, and a second source electrode and a second drain electrode on the second semiconductor layer and on opposite sides of the gate electrode, wherein the first source electrode is coupled to the second source electrode through a source connection overlapping the gate electrode, and the first drain electrode is coupled to the second drain electrode, such that the on current and off current characteristics of the thin film transistor may be constantly maintained regardless of alignment error.
摘要:
An image forming apparatus and a control method thereof to improve quality of an image in consideration of a change in posture of a print media. The image forming apparatus can include a transferred unit on which a visible image is formed, a transferring unit to form a transfer region through which the visible image is transferred onto a print medium, along with the transferred unit, a bias supplying unit to supply bias to the transferring unit so that a transfer electric field is produced in the transfer region, and a controller to control the bias supplying unit to supply different first to third biases to the transferring unit while at least first to third regions of the print medium pass through the transfer region, respectively.
摘要:
Disclosed is a plasma display panel fabricated by low temperature process at not more than 300° C. More particularly, the present invention provides a plasma display panel comprising at least one of a dielectric layer in an upper plate, another dielectric layer and barrier ribs in a lower plate, and a sealing material for the upper and lower plates which is prepared of a particular compound obtainable by curing organic monomer, organic oligomer or siloxane based oligomer having polymerizable functional groups; and, in addition, a method for fabrication of the plasma display panel.
