Abstract: Beneficial effects are obtained by topically applying ginsenoside F2 to the skin to improve skin conditions, improve water content on the skin surface and related benefits improving skin problems associated with acne or atopy, providing a skin whitening effect, helping control of sebaceous secretion, tightening skin pores, or improving skin complexion through enhanced blood circulation, but also to improve scalp and hair conditions, such as providing an anti-dandruff effect, promoting hair growth, or preventing generation of grey hair.

Abstract: Provided is a composition including, as an active ingredient, at least one selected from the group consisting of amines, amides and polyols. The cosmetic composition has an effect of preventing aging and may be applied in various industrial fields, including cosmetics.

Abstract: A separable portable multi-display device is provided. A portable multi-display device includes a main body panel housing having a first display, a sub-panel housing having a second display, and a coupling device for coupling the main body panel housing to the sub-panel housing such that at least one sides of the first display and the second display can contact each other. The panel housings are separable from and connectable to each other, a range of a border between the displays when the panel housings are interconnected being minimized so that the displays can be shown as if it is driven as a single screen.

Abstract: The present invention relates to a biomolecule-based electronic device in which the biomolecule with redox potential is directly immobilized on the substrate. The present invention enables to excellently exhibit the capability of a protein-based bio-memory device in which it is preferable to use the substrate on which cysteine-introduced recombinant proteins are effectively immobilized and a self-assembled layer (SAM) is fabricated. It becomes realized that a redox potential is regulated using intrinsic redox potential of the protein dependent on applied voltage. The present invention provides a novel operating method in which three potentials are applied throughout four steps. The present invention has some advantages of fabricating a protein layer in a convenient manner and inducing electron transfer by fundamental electrochemical or electronic operation.

Abstract: In a method of inspecting an identification mark, an image of the identification mark on a semiconductor wafer is obtained. The identification mark may be identified using the identification mark image. A region where the identification mark is formed may be inspected using the identification mark image after the identification mark is identified.
