In an information-oriented and internalized society of the future, the quality and price of goods made by each country will be equalized. That eliminates competition. But the design and appearance of products is an important factor in international competition. Indeed, design symbolizes a country's culture visually, and it can show the cultural identity and originality of a nation in international society. And that will play an important part that can contribute to creating added value. It is necessary to revive our people's old lyrical stories which are far away from our memory, and we badly need design development to revive traditional cultural merchandise through visual modernization. Among various Korean cultural inheritances, lotus is often seen in tiles, porcelains and folk stories. In this study, I chose lotus as the subject material of textile design development, and my intention for this study is to reflect Korean traditional cultural value as much as I can, and to develop textile design of Korean images by adding modern scenes. For that, first I researched lotus pattern materials and examples of cultural merchandise.

In this study, carbon/phenol composites were prepared from carbon fiber preform and phenol resin by RTM(resin transfer molding) process. And changes in the properties of the composite according to the pre-treatment of phenol resin was mainly studied. RTM process conditions were deduced from viscosity and thermal analysis of phenol resin which were rheometer and thermogravimetric analyzer(TGA). RTM process was performed under various injection and molding temperature. Characterization of the prepared C/P composites were evaluated by various analysis. Morphology of composites was analyzed by Micro-CT(MCT), Mechanical properties of composites were measured through the flexural properties. As results, volatile impurities of phenol resin were effectively removed at resin pre-treatment temperature of $100^{\circ}C$ and composite was sufficiently cured at molding temperature of $180^{\circ}C$.

The kapok fibers which are the functional fiber materials having natural hollows are environment friendly materials the demand and interest of which are increasing. The kapok fibers are environment friendly and natural hollow fibers which are 5-8 times lighter than cottons and have excellent performances in thermo keeping property, air permeability, bulkiness and resilience. In this study, the pretreatment according to the dyeing behaviors of kapok fibers were studied. Pretreatment(scouring, bleaching) were a variety of conditions. Scouring and bleaching, images of changed surfaces and cross-sections and dyeing behaviors of the dye-o-meter according to the concentration measured in meters and compared. Although the final exhaustion ratio of the kapok fibers scoured with a high concentration recipe was almost as same as that of the kapok fibers bleached with a high concentration recipe, the initial absorption speed of the kapok fibers scoured with the high concentration recipe was faster than that of the kapok fibers bleached with the high concentration recipe.

This paper presents a first step towards the understanding of water diffusion in RTM textile composite materials for aircraft applications and focuses on the development of experimental and numerical approaches to characterize the diffusion kinetics within the material. The method consists in making samples which are representative of the materials architecture and carrying out gravimetric tests on such samples. Analysis of results with the aid of a diffusion model reconstructing the architecture of the samples helps identifying the diffusion behaviour of the material.

The functional materials have been developed as a promising research topic toward the end uses for organic materials and applications. In this study, fluorescein based dye was synthesized by three step reaction. We have designed and synthesized the colorimetric dye through the reactions of fluorescein and methoxy group and ethylene diamine and squaric acid. The structure of the non-fluorescent spirolactam was elucidated by $^1H$-NMR, LC-Mass and FT-IR analyzes. Further studies are in progress to understand the effects of various substituent during the recognition process and to develop fluorescein based sensors for cations or anions.
