본 연구에서는 실내실험을 통하여, 하안침식을 고려한 망상하천에서 저수로의 이동특성을 조사하며, 2중 퓨리에 해석에 의하여 사주의 거동특성을 분석하였다. 실내실험은 평균입경이 1.4 mm이고, 표준편차가 1.35인 균일사로 10 cm 의 두께로 전체가 균등하게 채워진, 길이가 12 m, 넓이 2 m 수로에서 수행하였다. 각 시간별 하도의 지형변화에 대하여 2 중 Fourier 해석에 의한 지배적인 성분, 즉 모드(mode)의 변화를 분석하였다. 여기서 1-1 mode는 교호사주(alternate bars)이고, 1-2 mode와 2-2 mode는 2차 횡방향 모드로서 중앙 사주(central bars)를 나타낸다. 1-3 mode와 2-3 mode는 한 단면에서 횡방향으로 3개의 사주가 형성된 것(triple row bars)를 나타낸다. 초기에는 1-1 mode인 교호사주가 지배적이지만, 시간이 증가함에 따라, 교호사주인 1-1 mode는 감소하고, 한 단면에서 3개의 사주가 형성되는 2-3 mode가 지배적인 것으로 나타났다. 이러한 원인은 시간이 지나면서 사주가 발달하고, 하안침식이 되면서, 하폭이 증가하여 상대적으로 수심이 감소하면서 복렬사주가 발달하기 때문이며, Colombini 등(1987)이 이론적으로 예측한 결과와 잘 일치한다. 한 단면에서 3개의 모드가 나타나는 것은 하상에서 변화를 일으키는데 중요한 역할을 한다. 직선하도에서 사주의 수가 증가하는 것은 교호사주의 강한 비선형으로 상호작용하기 때문이다.

조선시대 끈을 일컫는 다회는 우리의 복식사, 문화사, 생활사가 녹아있는 산물로서 지역과 계층을 불문하고 다양한 분야에서 전반적으로 사용되었다. 국내외 다수의 유물이 현존하고 있으나 연구의 주요대상으로 선정되지 못하여 연구가 미흡하고 기법 전승 등에서도 접근성이 낮아 연구에 어려움이 많다. 본 연구에서는 도검의 패용(佩用)을 위해 사용된 광다회의 제작기법을 분석하여 다회의 비파괴적인 제작기법 분석 방안을 마련하고, 다회의 올바른 보존 및 계승에 기여하고자 하였다. 패용 광다회는 물건의 패용을 위한 용도로 사용되는 끈이며, 매듭을 맺기 위해 사용되기도 하여 현재는 매듭장에 의해 전승되고 있다. 제작원리는 원다회와 동일하고 다회틀 상판의 심지가 지지대 역할을 하기 때문에 제작된 다회의 중앙에 빈 공간이 존재하는 것이 특징이다. 이와 같은 다회는 3차원적으로 제작되어 제작기법이 복잡하고 현재까지 올의 개수와 배열에 따라 제작되는 다회에 관한 기초자료가 마련되어있지 않아 제작기법의 규명에 어려움이 많았다. 특히 제작기법의 추정을 위해 올을 해체하는 경우가 존재하지만 제작기법의 규명에는 어려움이 있고, 본래의 상태로 되돌릴 수 없다는 문제점도 있다. 따라서 다회의 비파괴적인 제작기법 분석방안 마련과 실제 유물에 대한 적용 가능성 평가의 필요성이 크다. 유물의 제작기법 분석은 다회 제작기법의 DB구축 결과를 바탕으로 하였고, DB구축을 위하여 다회의 도식화 및 복원샘플 제작, 형태적 특징 분석을 진행하였다. 또한 DB의 신뢰도를 높이기 위하여 유물의 X-ray CT 촬영으로 분석결과를 뒷받침할 근거를 마련하였으며, 촬영결과는 다회치기기법에 근거하여 제작기법을 해석하였다. 제작기법 분석의 대상으로 선정한 패용 광다회는 경인미술관 소장 도검(녹칠어피갑금동장별운도, 어피갑금동장곡병환도)의 패용을 위한 것으로 다회의 예술성, 기능성과 상징성을 겸비한 유산이며 광다회가 온전히 남아있어 띠돈을 비롯한 패용장식이 모두 온전한 유물이다. 유물의 제작기법 분석결과를 토대로 짜임형태를 관찰하였고 2점 모두 좌우측면에서 1회 교차된 것임을 알 수 있었다. 짜임형태 길이비 측정을 통해 20개의 올을 사용하여 제작된 것으로 확인되었다. X-ray CT 촬영결과 DB의 분석결과와 동일한 결과가 도출되어 차후 국내외에 산재되어있는 다회의 분석 및 연구를 위한 기초자료로서 활용이 가능할 것으로 사료된다. 이번 연구를 통해 미력하게나마 소중한 전통문화의 보존 및 계승, 발전에 도움이 되기를 바란다.

The boron-nitrogen-containing phenol-formaldehyde resin (BNPFR)/$SiO_2$ nanocomposites (BNPFR/$SiO_2$) were synthesized in-situ, and structure of BNPFR/$SiO_2$ nanocomposites was characterized by FTIR, XRD and TEM. The loss modulus peak temperature $T_p$ of BNPFR/$SiO_2$ nanocomposites cured with different nano-$SiO_2$ content are determined by torsional braid analysis (TBA). The thermal degradation kinetics was investigated by thermogravimetric analysis (TGA). The results show that nano-$SiO_2$ particulate with about 50 nm diameter has a more uniformly distribution in the samples. The loss modulus peak temperature $T_p$ of BNPFR/$SiO_2$ nanocomposite is $214^{\circ}C$ when nano-$SiO_2$ content is 6 wt%. The start thermal degradation temperature $T_{di}$ is higher about $30^{\circ}C$ than pure BNPFR. The residual rate (%) of nanocomposites at $800^{\circ}C$ is above 40 % when nano-$SiO_2$ content is 9 %. The thermal degradation process is multistage decomposition and following first order.

This study examines 74 pieces of textiles of Daegaya found in the Jeesan-dong Tomb and Saeng-cho Tomb, and analyzes their characteristics and weaving techniques. Dagaya is known to have produced ramie and hemp from bast fibers. The hemp textiles were all woven in plain weave, and the ramie textiles were woven either in plain weave or plain braid. The ramie textiles were slightly more dense compared to the hemp textiles, however, both had average densities between 0.92 to 0.93, showing that they are balanced plain weave textiles. It was also found that S twist threads were used in the production of the hemp and ramie textiles. The dyed textiles on iron remains were found to be the oldest textiles to use dying techniques for patterns. Silk textiles were woven in plain weave, twill weave, and leno weave. All of the silk were made with non-twisted thread. The densities were between 30 to 58.3 and the the density rates were 1.0 to 2.5 for plain weave silk, this showed that varieties of plain weaver created by different densities of warp and well. The average density of cho was $53.4{\times}22.5/cm^2$ the density rate was about 2.40, therefore warp was woven more dense compared to the weft. There were degummed and raw silk used in silk textiles, but most of them were found to be degummed thread.

This study was designed to observe the effect of ethanol extracts from fish flour on the nucleic acid metabolism in rats. Young rats, weighing 75-85g were used as the experimental animals and diet used were 8 kinds; diet supplemented with 10% fish flour, diets which were supplemented with the extracts and or remainders of fish flour after extracting by either 76% or 96% ethanol to the rice diet, respectively, and diet supplemented with 6% casein. After feeding corresponding diet for 40 days, RNA and DNA contents, and DNase activities in the liver, kidney and braid were determined. The results obtaioed from this study are summarized as follows: 1. The RNA contents of the ethanol-treatment groups are, in the liver and kidney, similar to, and in the brain, generally higher than, that of the control group. 2. The DNA contents of each organ show no difference between ethanol-treatment groups and control group, but in the liver, of ethanol extrat groups are lower than casein group. 3. the DNase activity of each organ in the ethanol-treatmeut groups, is generally lower than the control group. The above results indicate that ethanol extracts from fish flour have influence on the nucleic acid metabolism.
