The purpose of this study is to develop high value-added uniform design in response to climate change, and produce high sensitivity uniforms that conserve the energy of its wearers. The scope of the study encompassed entire production stage from the product planning stage to developing a prototype to collecting consumer ratings to securing intellectual property. The results of the study are as follows. First, the material was developed that maximizes insulation by replicating human body heat radiation and raising the temperature by 5 degree Celsius. Second, through Time to Market system, a luxurious synthetic wool material was developed, and warm effect was achieved. Third, pattern design engineering for easy movement and design development allowed the realization of uniform design that is compatible indoors and outdoors as well as respond to highly active climate change. Fourth, Fifth, the developed design was registered and intellectual property rights were obtained.

A CJ9 bacterial strain, which showed antifungal and antibacterial activities, was isolated from meju and identified as Bacillus polyfermenticus based on Gram staining, biochemical properties, as well as its 16S rRNA sequence. B. polyfermenticus CJ9 showed the antimicrobial activity against the various pathogenic molds, yeasts, and bacteria. The antibacterial activity was stable in the pH 5.0~9.0, but the activity was lost at $37^{\circ}C$ for 24 hr. The antifungal activity was stable in the pH range of 3.0~9.0 and reduced at $121^{\circ}C$ for 15 min, but antifungal activity was not completely destroyed. The antibacterial activity was completely inactivated by proteinase K, protease, trypsin, and $\alpha$-chymotrypsin. The antifungal activity was also completely inactivated by protease and $\alpha$-chymotrypsin, and reduced its activity by proteinase which indicated that the antifungal and antibacterial compounds have proteineous nature. The apparent molecular mass of the partially purified antifungal compound, as indicated by using the direct detection method in Tricine-SDS-PAGE, was approximately 1.4 kDa. The molecular mass of the antibacterial compound could not be determined because of its heat-liable characteristic.
