Abstract:
One or more embodiments of the present invention describe a novel use of capsanthin and/or fatty-acyl ester of capsanthin to inhibit both the differentiation of pre-adipocytes to adipocytes and the accumulation of fat in the adipocytes. One or more embodiments of the present invention are based on findings that capsanthin contained in some natural products such as red pepper, paprika, bell pepper, etc. have anti-adipogenic activity by inhibiting both the differentiation of pre-adipocyte into adipocyte and the accumulation of fat in adipocytes, Therefore, this findings provide a functional food and a pharmaceutical composition wherein capsanthins and the extract of any natural products containing the same components are included in the functional food and the pharmaceutical composition, to offer obesity prevention and/or treatment effects.

Abstract:
A semiconductor device includes a fuse transistor for fuse programming and a fuse block connected to the fuse transistor, wherein the fuse block comprises a fuse line and a heat spreading structure connected to the fuse line. The electrical fuse employs the heat spreading structure connected to the fuse line to prevent a rupture of the electrical fuse such that heat, which is generated in the fuse line during a blowing of the fuse line, is spread throughout the heat spreading structure. Thus, a sensing margin of the electrical fuse can be secured and a deterioration of devices adjacent to the electrical fuse by heat generated in the electrical fuse can be prevented.
Abstract:
Herein are disclosed a magic code for marketing and a medium using the magic code. The magic code includes a second design layer in which a character, numeral or symbol pattern is regularly and repeatedly formed in a specific color and some of the character, numeral or symbol patterns are deleted; a third design layer in which boundaries of character, numeral or symbol patterns containing the prize winning message are formed in a color similar to the color of the character, numeral or symbol patterns of the second design layer; a fourth design layer in which dots are formed in a color having a complementary color relationship with the color of the character, numeral or symbol patterns of the second design layer; a fifth design layer in which dots are formed in a color similar to the color of the character, numeral or symbol patterns of the second design layer; and the sixth design layer in which the boundary of the character, numeral or symbol pattern is regularly and repeatedly formed in a color similar to the color of the dots of the fourth design layer. The layers are sequentially stacked one on top of another based on brightness, saturation and complementary color relationships.

Abstract:
A sealing member, a photoelectric conversion device having the same, and a method of preparing the same are disclosed. In one aspect, the sealing member for the photoelectric conversion device joins a first substrate and a second substrate, which face each other, and seals an electrolyte solution in a space therebetween. An edge of the sealing member may include a rounded portion and a radius of a circle including the rounded portion is about 50% or more of the width of the sealing member. The sealing member may serve to reduce leakage of the electrolyte solution due to lowered adhesion of the sealing member or a wrinkled sealing member, and thus, improve reliability of the photoelectric conversion device.
