  • 서울대 사범대 화학교육과 백명현교수는 요즘 초분자를 이용해 새로운 작품을 만들고 있다. 백교수의 전공은 무기화학으로 초분자소재 화학연구에 심혈을 기울이고 있는데 이는 거대한 분자를 이용해서 초분자를 만드는 연구로 그녀의 연구결과로는 기억매체로 응용될 수 있는 강자성 물질의 합성에 중요한 단서를 제공한다는데에 의미가 있다. 백교수는 이 분자체를 이용해 분자 벽돌담과 분자 벌집들을 합성해냈고 그 모양의 꽃무늬 레이스 같다고 하여 이름을 꽃무늬 레이스 초분자 라고 붙였다.

  • The purpose of this paper is to analyze Hirata Oriza's three plays, "Scientific Minds," "Monkeys on the Northern Limit Line" and "Balkan Zoo" with Lyotard's postmodern scientific view. Liotar, who claims that science and narratives follow the rules of their own pragmatic use, talks about the incommensurable parallelism between the two. Hirata Oriza points out that humans rely on narratives in the postmodern world. This paper analyzes Hirata Oriza's plays in three aspects. First, in the postmodern world where the master narrative has disappeared, it identifies the point where the boundaries that define the identity of human beings under the lost and developing science technology are fading. Second, we look at the pattern in which the parallelism between scientific knowledge and narrative knowledge is constantly diluted due to the characteristics of humans who understand the world by leaning on narrative. Finally, the aspects of small narratives are idetified, raised by individuals to comfort themselves toward a world where the master narrative disappears and is justified only by maximizing performance.

  • This thesis is to study about The Issue of Treating Information, according to the circumstance of Digital Media in Contemporary Design. The Digital Design is being able to be organized by developed Science and Technology. Ultra fashionable mode of digital design is leading human life more comfortable and serviceable: and proceeded by technology aheaded by science Developed Computer will help the Space science and virtual reality. and They will lead more developed industrial culture. The design is influencing international society and economic circumstance, and it's making the changedness of product and commercial route. virtual reality and simulation made by developed science is resulting in new design revolution in our society. Especially, it is able to make more bigger result in image breaking and reassimilation. The technology of developed information treating infra is able to transmit & receive a message, which are beyond our sensual boundary and is the meaning of the human-being's progressive development of science culture. Developed information treating methodology made by technology and science of restoration will be Neo-reality for artists and are the cause of great changedness in 21st century's art & design.

  • Functionality changes by germination of giant embryonic rice and pigmented rice were evaluated with focusing on antioxidative activities of 70% ethanolic extracts. Overall, reducing power of giant embryonic rice and pigmented rice was higher than that of normal brown rice, and the germination of rices tend to enhance their reducing powers. In vitro and ex vivo experiments employing linoleic acid peroxidation and rabbit erythrocyte membrane peroxidation systems, respectively, revealed inhibitory effect on lipid peroxidation was highest in pigmented rice, followed by giant embryonic rice, and normal brown rice from high to low order. Superoxide radical-scavenging activity decreased in order of pigmented rice > giant embryonic rice > normal brown rice, and germination also enhanced their superoxide scavenging ability compared to non-germinated controls. Hydroxyl radical-scavenging ability was highest in pigmented rice, followed by giant embryonic rice, and normal brown rice. Despite marked enhancement in hydroxyl radical-scavenging ability of normal brown rice by germination, order of scavenging ability was not altered among germinated rices. Same trend as with in vitro ROS scavenging was observed for ex vivo scavenging potency on ROSs generated by TPA stimulation in HL-60 cells. Germination-associated differential increase in ROS scavenging ability of pigmented rice and giant embryonic rice, characterized by no induction of cytotoxicity, was observed.

  • This study was carried out to investigate the supplementary effects of giant embryonic rice, which has over two times of embryo size compared the normal rice, on lipid metabolism of insulin dependent diabetic rats. Streptozotocin induced diabetic rats were fed four kinds of experimental diets com starch diet as a control (C-D), a polished rice diet (R-D), a brown rice diet (BR-D) and a giant embryonic rice diet (GER-D) respectively, for 6 weeks. Diet intake body weight, organ weights and lipid levels of serum, liver and feces were measured. There was significant difference in diet intake and body weight among experimental groups. The concentrations of serum triglyceride and total serum cholesterol of BR-D and GER-D groups were lower than those of others. The total hepatic cholesterol level was the lowest in GER-D group. The contents of total lipid and total cholesterol excreted in feces of BR-D and GER-D groups were higher than those of C-D and R-D groups. These results suggested the giant embryonic rice diets can effectively reduce serum triglyceride level and total hepatic cholesterol level in insulin dependent diabetic rats, and hypolipidemic effects be due to increasing fecal lipid excretion.
