Antioxidation synergism between ZnDTC and ZnDTP in a kind of mineral base oil was investigated by RBOT. The results indicate that there is antioxidation synergism between the two additives. FTIR analysis show that the oxidation products in the tested oils containing the two additives are much less than those in the tested oils containing the single additive alone.

금융산업에서 증권사의 주식 트레이딩 시스템은 단 1분의 장애에도 손실이 매우 큰 응용 시스템이다. 특히, 트레이딩 시스템 구축 환경이 메인 프레임 환경에서 클라이언트/서버 환경으로 전환됨으로써 추가적으로 안정성이 시스템의 최우선 목표로 인식되고 있다. 이와 같은 인식 하에 일반적으로 IT환경에서 제시하고 있는 가이드라인에 의한 시스템 구축이 당연시되고 있지만, 트레이딩 시스템은 업무의 특성상 정규화된 표준 가이드라인을 따를 경우 신뢰도를 보장할 수 없음으로 비정규화된 방법으로 해당시스템을 구축하는 것이 현재 실정이다. 본 논문은 TP 모니터 계열의 미들웨어를 통한 3-Tier 클라이언트/서버 환경에서 X/Open DTP 모델에서 정규화된 표준 가이드라인인 XA 인터페이스 기반 시스템과 비정규화된 방법인 Non-XA 인터페이스 기반 시스템을 증권사 트레이딩 시스템 환경 하에 구축하여 비정규화 방법의 신뢰성을 증명한다. 그 신뢰성 증명의 방법으로는 시스템 실패를 가정한 극복(take-over) 테스트 시 주문 데이타의 에러와 이의 복구방안을 XA와 Non-XA 인터페이스 두 경우를 대상으로 수행한다.

For high quality DTP products, it is important to optimize the parameters of media, pre- and after-treatment, ink, printer, etc. This study investigated the effect of types of fabrics(media) as a DTP parameters. Especially, the effects of media properties such as yarn twist and knitted fabric structure, on printability and color difference were examined. Two types of cotton yarn twist(830 and 1630 twist/meter) and five knitted structures of media were prepared with a single circular knitting machine. The K/S values of hard-twist samples were higher than those of normal-twist samples in every media structures. It is more effective to use the knitted fabrics of a hard-twist yarn to obtain dark color in the printing above input level value 60 where the printability improvement was most pronounced in case of plain structure. Among the five media structures a plain structure was the highest and that of corduroy was the lowest in terms of K/S values. Also ${\Delta}E$ values and lightness of the hard-twist yarn samples were smaller than that of normal-twist yarn samples when ${\Delta}E$ values were tested by using a standard of a normal twist yarn sample with a plain structure, which was increased in the case of corduroy structure.

In the direct digital textile printing process, the pre-treatment process is an essential condition for products by forming a clear pattern by sticking and penetration of DTP dye without spreading on the fabric. Recently, pre-treatment agent is changing from high viscosity to low viscosity in order to reduce defects of fabric during pre-treatment process. In this study, pre-treatment agent of acrylic polymer with low viscosity(less than 50cps) was prepared according to the solid content of the polymer, pre-treated on the cotton fabric, and direct DTP printing was performed to compare the color and sharpness. As a result, it showed high color at a viscosity of 50cps or less. When the solid content of the polyacrylic acid having a high molecular weight(A1) was 2.5wt%, when the solid content of the polyacrylic acid having a low molecular weight(A2) was 1 - 1.5wt%, the color was the best. And when the solid content of A1 and A2 was 1.5wt%, the degree of spreading was small and A1 was superior to A2 at the sharpness.
