The Purpose of this study was to prospect new costume culture of 21st Century and to understand the meaning of clothing and clothing behavior which represent on Korean Seasonal Costumes expressed in novel, Honpul. The results were as follows; There are special Costumes in a Year. They are New year, First full moon, Servants day, making seasonings, Doo Rae, Wha-cheon Nori(enjoying blossoms) Costumes during spring season, Dan-Oh Costume in summer and Ya-Kwang-Gui(keeping shoes at all night), Su-Ya(overnight), Yeam-Bal(burning dropped hairs) Costume in winter season. There were many relationship with clothing in new year, Wha-cheon Nori and Servants day Costumes, but they only had adorning meaning without special symbolic or incantational meaning. Clothing and clothing behaviors in Seasoning making day Costume, Dan-Ho costume and Ya-Kwang-Gui, Su-Ya, Yeam-Bal Costumes contained practical meaning with incantational meaning. There were Servants day costumes and Doo-Rae Costumes for lower classes, New year and Wha-cheon Nori costumes for the higher classes. But the First full moon day costume was for both classes. This study will make us to grasp the meaning of clothing culture with Korean Seasonal Costumes, and be useful to measure the changes of Korean costume cultures.

This study examined the catalytic property of Ni-catalyst used in the gas purifying process to manufacture inert gases of N2 and Ar with high-purity over 9N for semiconductor industrial applications. Two types of Ni-catalysts with a cylindrical shape (C1) and churros shape structure (C2) were compared for the assessment. Optical microscopy and FESEM were used to analyze the shape and microstructure of the Ni-catalyst. EDS, XRD, and micro-Raman characterization were performed to examine the composition and properties. BET and Pulse Titration analyses were conducted to check the surface area and catalytic property of the Ni-catalyst. From the composition analysis results, C1 contained a relatively large amount of graphite as an impurity, and C2 contained higher Ni contents than C1. From specific surface area analysis, the specific surface area of C2 was approximately 1.69 times larger than that of C1. From catalytic property analysis, outstanding performance in O₂ and CO impurity removal was observed at room temperature. Therefore, C2, having low-impurity and large specific surface area, is a suitable catalyst for the high-purity inert gas process in the semiconductor industry because of its outstanding performance in O₂ and CO impurity removal at room temperature.
