LGP is a key component of LCD back light unit because it determines brightness and sharpness of the display image. Usually, it has optical patterns fabricated on the bottom surface. These optical patterns convert point or line sources placed in the side of LGP to plane source at the top surface by changing the propagating direction of the incident light. In the present paper the LiGA-reflow method was applied to fabricate the LGP mold. Furthermore, the optical simulation considering the replication ratio of pattern height was applied to the pattern design. The optical simulation through systematic correction scheme was adopted to find the optimum distribution of pattern density. Finally, the stamper fabricated by this method was installed in the mold and LGP was produced by injection molding. As a result of luminance measurement for the final product, the average luminance and luminance uniformity was measured 3,180 nit and 84%, respectively. Consequently, the mold fabrication method using the LiGA-reflow and optical simulation(CAE) can save the expense and time compared with the existing fabrication methods(laser ablation and chemical etching).

The purpose of this paper is to show that a shape pro-duced by natural factors such as weather, environments, etc., can be introduced into the emotion of a design, and to make a design process by planning a Korean image and characterizing its concept. Human beings, nature, man-made objects, and society have their own functions in an environmental structure. When all their functions are kept in working order, human beings come to discover orderliness out of which they can absorb pleasure. They cannot look into their own inside but they can trace back in their memories a variety of panoramic experiences which have been embed-ded onto their identity during their lifetime interactions with an empirical world. Children first acquire a way of cognition in the space, a comprehensive premise, connecting a specific place and an object of cognition. Such subconsciousness forms sky-lines of mountains, seas, and trees under the sky, and produces axis lines and beehived domes under the influ-ence of natural, cultural, and social factors, forming a folk culture. A subconscious composition of existential space is extended. A subconscious composition of existential space is extended to the areas of environmental design, product design, and fashion design. The development of a concept of place and space as a system is a necessary condition for discovering an existential foothold.

This study is to develop tourist souvenir which designed image of butterfly, the symbol of Hampyeong Butterfly Festival, using natural dyeing product, the specialty of Namdo region. Results of market survey of tourist souvenirs for Hampyeong Butterfly festival showed that souvenirs of butterfly design sold in market which were not discriminated from that of general products and locality or characteristic of the region could not be exhibited. According to the results of market survey, design of souvenirs of Hampyeong Butterfly Festival is as follows; Butterfly pattern of hinge and Dangcho pattern are developed to graphic motive of modern sense with traditional beauty to make design which can be consumed by modern consumers in their actual life and then proper pattern is planned by combining, repeating and disassembling them. Such a pattern is applied to souvenirs like T-shirts, necktie and scarf to make tourists feel identity and unification of the festival visually. In addition, design of souvenirs was made to be coordinated with casuals. Therefore, visual factor could be extracted from Korean cultural heritages suitable to concept of local festivals and it is considered that ways of commercialization and development of traditional pattern suitable to consumers' demands can be suggested.

Streptococcus mutans, one of a major causal agents of dental caries, is component of the dental plaque and produces various organic acids such as lactic acid as the end-product of glycolysis. In this study, we isolated S. mutans from Korean children with caries and also investigated the expression of protein under acid stress. S. mutans was identified at the species level using a 16S ribosomal DNA sequencing comparison method. The primer specificity was tested on eleven S. mutans strains isolated from Korean children with caries. The data showed that eleven strains are S. mutans. At treatment of concentration of 20 mM lactic acid in the mid-log phage, K-7 exhibited the highest maximum culture OD compared with those of other groups. As a consequence, we examined the expression of protein under 20 mM lactic acid stress using S. mutans K-7. The results of 2D gel electrophoresis by image analysis showed that thirteen proteins are up-regulated under the stress. Further study is being focused on amino acid analysis by mass spectrometry in order to analyze those spots.
