Abeliophyllum distichum Nakai belonging to Oleaceae is only species in Korean endemic genus, Abeliophyllum. Abeliophyllum distichum (AD) is divided into various types according to flower shape and color. AD is known to have various colors such as white, pink, and ivory. Recently, light yellow flowers have been registered as new varieties (Okhwang 1ho). To date, various ecological and morphological studies on AD have been carried out, but no studies have been made on the phytochemicals and activities according to various traits. In this study, we analyzed the phytochemicals and antioxidative activities of from four kinds of flowers (white, pink, ivory, light yellow) in full bloom. The contents of phytochemicals such as chlorogenic acid, Hirsutrin, Rutin, Acteoside and Isoacteoside were analyzed by HPLC. Antioxidant activity was evaluated by DPPH, ABTS. As a result, the content of each substance varied according to the flower color. These results will provide basic data for evaluating the usefulness of genetic resources in Korea and developing new functional materials in preparation for the Nagoya Protocol.

In roll forming process, a sheet metal is continuously progressively formed into a product with required cross-section and longitudinal shape, such as a circular tube with required diameter, wall-thickness and straightness, by passing through a series of forming rolls in arranged in tandem. In this process, each pair of forming rolls installed in a forming machine play a particular role in making up the required cross-section and longitudinal shape of the product. In recent years, that process is often applied to the bumper rail in the automotive industries. In this study, a optimal roll flower model and proper roll-pass sequence can be suggested by analyzing courcenter strain and longitudinal strain according to the roll-pass with FEM simulation. And also effects of the process parameters on the final shape formed by roll forming defects a evaluated.

This study selects camellia flowers as a material for design development and created patterns by simplifying the image of camellia flowers and combining it with a geometrical motif. It it applied them to various fields to develop design content for fashion cultural products that were Korean, modern, and competitive. For this purpose, this paper used Adobe Illustrator CS2 to turn the camellia flower into a motif and develop it into a pattern. Based on the realistic form of camellia flower, this paper set 3 basic motifs of new formative images, using graphic elements, such as omission of a form, simplification, overlapping, repetition, and reduction, and it also developed two transformed motifs by applying a different color to each motif. This paper repetitively arranged each motif in the background of a diamond shape, a square, and a circle, and it combined each motif with the patterns of marcel, stairs, and stripes, through which it expressed the combination of the geometrical patterns and the flower patterns. Through the application of repetitive and combined patterns of each motif, the enlargement and reduction of motifs, the repetition of motifs, the combined use of motifs, and the change in colors and layout, this paper used the motifs of various fashion cultural products, such as scarves, neckties, and T-shirts.
