  • Fetal Bovine Serum (FBS) is an essential substance added to animal cell culture medium. However, its composition is unclear causing problems such as development of an immune response when cultured cells are transplanted into the human body. In this study, silk sericin, silk fibroin, and hemolymph obtained from silkworms were added to the cell culture medium in order to determine if it can replace FBS. After establishment of the cell culture, cell proliferation and expression levels of cell growth-related genes were compared with those of control cells (cells cultured in the medium with 10% FBS). Results showed that the test group treated with silk fibroin extracted from a Korean silkworm variety, Kumokjam could replace 10% FBS. In addition, expression levels of cell growth related genes such as Fibronectin and TGF-β1 increased significantly in cells cultured using silk fibroin, depending on the concentration used in cell adhesion and cell proliferation [24]. To date, no studies have been conducted to find a replacement for FBS. Thus, this study was carried out to develop a substitute for FBS by using silkworm-derived alternatives such as silkworm hemolymph, silk sericin, and silk fibroin, which are cheap and have various physiological effects, cell promoting effects, and can be mass produced.

Second, the ethnic sense is influenced by the growing background in his childhood and can be characterized as compromise among the multi-national design features. It is certified by the contrasting images, styles, expressions, materials, ornament elements, and so forth with the worldwide ethnic senses centered by the southern France and Spain. Third, the hybrid sense as the essential characteristic shows the uniqueness in his design by not only combining the modern materials, technologies, and futuristic emotion but also liberally compromising and associating the emotions based on a mixture among the follows; the historic representative styles, the foreign materials, the diversity between the Eastern and Western culture, and all elements, details, trimmings In the fashion design.

  • The purpose of this study was to develop children-friendly education materials based on food replicas for the dietary education of lower grade elementary students. Through a literature review on current dietary problems and dietary education for children, five education themes were chosen: balanced diet, seasonal food, traditional food, noodle culture, and making instant noodles. A total of 304 key food items for food replicas were selected based on the themes: six basic food groups (113 items), balanced meals (37 items), dietary habits (74 items), spring foods (13 items), summer foods (17 items), autumn foods (16 items), winter foods (11 items), Korean traditional foods (52 items), Korean native noodles (18 items), noodles from foreign countries (19 items), and making instant noodles (46 items). Next, a food replica database was developed consisting of name of the food, picture, size, ingredient, recipe, reference, and attached code. Powerpoint slides and teaching plans for all education themes were developed utilizing the food replicas in order to raise interest and understanding of serving size and intake amount. This research provides a basis for the development of food replicas as effective dietary education materials for elementary students and their use in extra-curricular activities, after school programs, community health centers, or food companies.

  • It is our common understanding that biological materials like microorganisms, tissue and cell cultures, seeds, plants and animals are inevitable resources for the development of science and technology. Culture collections which are reservior of biological materials now occupy a central position in life sciences and biotechnology. The World Data Center of Microorganisms (WDC) is a infrastructure of culture collections in the world realizing quick and smooth exchanges of information and microorganisms to support research and development in those fields. The WDC was relocated from University of Queensland in Australia to out institute RIKEN in 1986. This article introduces a function for WDC in RIKEN (RIKAGAKU-KENKYUUSHO, the Institute of Physical and Chemical Research)

  • As Backje(B.C. 18-A.D. 600) is the whole area of Chungcheong, Jeonra, Kangwon and Gyeongsang provinces, the son of the founder of Goguryeo, King Onjoe, making the castle Wu'irae capital of the nation, founded Backje. The capital was transferred to Hansung by B.C. 5 and then to Gongju by A.D. 475. Backje governed the east of China and the northeastern coast. Due to the effect of Chinese culture there are remarkably Chinese cultural elements in dress and its ornament of Baekje. Therefore on the side of cultural part, the noble culture was formed more polished than that of Goguryeo, which affected the culture of dress and ornament. And also there were class differentiation noticeably. Baekje created splendid culture and affected the culture development of Shinra and Japan. The motive of culture creation could be the top of three countries in the foreign trade because there were geographically the widest vast plain and coastline which stretches out from north to south. Although there haven't been many materials about the cultural heritage and records more than other countries, through the modern visual point its design is fresh and more elegant those of other countries. But the fact is that there are few materials related to Baekje. What is worse, there rarely remains all original form and most of them are broken and lost. According1y, we cannot understand not only an original form of Baekje culture and but also the meaning included in it. It goes without saying that there are few materials about the clothes and fabrics. As understanding the culture of Baekje itself is insufficient, a culture enterprise utilizing it - to improve both the added value and economical achievement while combining the latest culture resources with other fields - hasn't been successful. In this study, the purpose is to improve economic power through commercialization and industrialization of the sources of the culture of Baekje. By reanalyzing a form and an image of Baekje relics, it is designed with new motif and modem preference on the condition of our peculiar cultural heritage. And while using this motif with Jacquard pattern, we made it possible to be applied to real life such as interior trinkets, etc.
