Three vat dyes have been applied to regular viscose rayon and their dyeing and wash fastness properties were evaluated. Particle size determination was undertaken to obtain information about the size of dye particles converted by a reducing agent, to see if dye particle size has an affect on dyeing properties of regular viscose rayon. It is observed that viscose rayon exhibits more dyeability with reducing agent concentrations between 5-7.5 g/l. Also, we found that the vat dyeing system is greatly affected by the particle size of the vat dye converted to leuco form by a reducing agent.

Modern military equipments are often required to be mounted on a truck for their survivability and operation performance. Special units installed on the truck at times experience serious shock vibration caused by obstacles of road and/or uncommon road shape. It is then essential to analyze the travel performance of truck-mounted special units for their survivability and performance. In this paper, shock responses of the equipments subjected to bump passing and wash board road are experimentally obtained and also analyzed via FEM. Modified bump configuration and road profile considering the interface with tire are suggested. Analytical results considering this modification show good agreement with test results.

In this article, arrowroot is extracted in distilled water, and its dyeing properties on wool, nylon, and silk were investigated. Also the effect of mordanting (Al, Cu, Sn, Fe and Cr compounds) on the wash fastness are measured. The wavelength of maximum absorption of the arrowroot extract appears at 250 and 300nm below pH 7, but they shifted to longer wavelength at higher pH values. It appears that the optimum condition of the dyeing of wool, nylon, and silk fabric with arrowroot extract is $60^\circ{C}$, 60 min, and pH 4.0. Mordant treatments are effective in improving wash fastness of polyamide fabrics.

1980년대초에 Wash 1400의 위험성을 분석연구한 프랑스의 안전담당기관과 EdF는 내부압력초과로 격납용기의 파손을 가져올 수 있는 사고가 발생했을 때 대기로 방출될 지도 모를 가스와 Aerosol 누출량을 상당량 줄이기로 목표를 세웠다.

Korea and Japan have a cultural homogeneity because they were affected by China. However, each country has developed its own original culture due to their own national characteristic and endemism, In traditional clothing, though Korea and Japan share the same origin, they have developed their own form, Hanbok and Kimono, which have completely different looks. The differences in the traditional clothing is the result of the differences in each country's aesthetic sense, which is reflects in the artwork of those days. Ink-and-wash painting was the typical painting form in East Asia, so Korean and Japanese ink-and-wash painting from that period can be used to observe the differences in the aesthetic sense. This study aims to search for commonly shared aesthetic sense in the design process of Hanbok and Kimono by analyzing the styles of a representative Korean painting, "Sehando(Wintry Days)" and a representative Japanese painting, "Pine Trees Screen". H. Wolfflin's methodology influenced not only painting, but also architecture and sculpture. Therefore, this theory can be applied to clothing, which can be considered a type of sculpture. Modernization of traditional clothing has to start by analyzing the aesthetic sense of artisans that have affected the design of traditional clothing. To spread Hanbok globally and differentiate it from Japanese clothing, we have to acknowledge the differences between Korean and Japanese aesthetic sense, and based on this, we have to develop the design of Hanbok.

Functional residual capacity (FRC) is an important diagnostic parameter measured using $N_{2}$ analyzer. Since $N_{2}$ analyzer is expensive as well as cumbersome for use of noisy vacuum pump, the FRC measurement becomes possible only in large well-equipped hospitals. The present study introduced a new $TN_{2}$ wash-out technique to measure FRC by $O_{2}/CO_{2}$ analysis, which is relatively cheaper and much simpler to apply. Slower $O_{2}$ response was compensated for high frequency to be coincided with $CO_{2}$ response, thereby enabled indirect, but accurate $N_{2}$ concentration measurement. FRC was estimated by continuous integration of expired $N_{2}$ volume obtained with air flow signal. Experiment with 3 L syringe, a standard calibration device recommended by the American Thoracic Society, demonstrated less than 1% error at 0, 1, and 2 L. Correlation coefficient was almost ideal, guaranteeing linear estimation of FRC. The present technique is inexpensive and simple to apply, thus should he of great convenience.

폐 RHDM(Residue Hydrodemetallation) 촉매상에 침적된 비활성화 성분인 탄소, 황 을 고온배소 처리하여 제거한 후, 과량 침적되어 있는 바나듐은 초음파 교반기에서 5~15wt% 옥살산 수용액을 이용하여 $50^{\circ}C$, 5분 조건하에 바나듐 추출량을 조절함으로써 NOx 저감을 위한SCR(Selective Catalytic Reduction) 촉매로의 적용 가능성을 확인하고자 하였다. 폐촉매와 단계별 처리된 RHDM 촉매를 대상으로 상압반응기상에서 NOx 저감 효율을 측정하였고, 촉매의 성분분석은 ICP, C & S analyzer 및 XRF를 이용하여 분석하였다. 10wt% 옥살산 수용액으로 바나듐을 침출한 촉매가 가장 안정적이었으며 높은 NOx 저감 효율을 보였다. 이를 메탈폼 형태의 지지체에 워시코팅한 촉매는 상용 SCR 촉매와 동등 수준의 NOx 저감 효율을 나타내었다. 따라서 폐 RHDM 촉매의 처리 조건 조정에 관한 후속 연구를 통하여 각 적용처에 적합한 SCR 촉매로의 이용 가능성은 충분할 것으로 사료된다.

This study was conducted to investigate the food components of cooking drips from shell oysters steamed under various retort pressures. Among the drips from shell oyster steamed under different retort pressures (1.0, 2.0, 2.5, 3.0, 3.5, 4.0 and 4.5 kg/$cm^2$) the oyster drip obtained at the 4.5 kg/$cm^2$ of retort pressure had the highest degree of brix, yield, crude protein, glycogen and trichloroacetic acid soluble-N contents, while its salinity was the lowest. In the results of food safety test, the presence of E. coli (18 MPN/100 g>) and viable cell (30 CFU/g>) in the oyster drip was in acceptable level as a food-stuff. However, the sensory evaluation such as color, flavor and taste, total amino acid and free amino acid contents of cooking drip from shell oyster steamed at 4.5 kg/$cm^2$ were inferior to those of oyster wash water. Differences in the major amino acids of total amino acid and free amino acid between oyster cooking drip and oyster wash water were also found. The results suggested that the effective use methods of oyster cooking drip should be investigated.
