ACQ 처리 목재에서 약제의 침투깊이를 확인하기 위하여 지금까지는 Cu 성분만을 대상으로 침윤도를 측정해 왔다. 본 연구에서는 Cu 이외에 ACQ의 유효성분 중에 하나인 DDAC의 침투깊이를 조사할 수 있는 DDAC 발색처리 방법을 개발하고 다음과 같은 결론을 얻었다. DDAC 성분은 2',7'-dichlorofluorescein 발색 지시약과 반응하여 진한 주황색으로 발색한다. 이와 같은 발색 반응은 DDAC 용액에서 뿐만 아니라 ACQ 처리 목재에서도 진행되어 DDAC가 침투되어 있는 목재 조직에서는 동일하게 주황색으로 발색한다. 본 연구를 통하여 개발된 DDAC 발색기술에 의하여 방부제 난주입성 수종인 가문비나무에서 Cu에 비하여 DDAC의 목재 침투성이 우수한 사실을 육안으로 확인할 수 있었으며, 다른 난주입성 수종에 대해서도 Cu와 DDAC의 침투성 차이를 조사할 필요가 있다.

This study explores the kinds and types of dyes used in the Joseon Dynasty. Some literature including "Sanga Yorok", "Gyuhap Chongseo", "Imwon Gyeonjeji" were reviewed for this purpose. The findings are as follows. The colors obtained from the dyes were divided into seven color series, such as red, yellow and orange, green, blue, purple, brown, gray and black. These are practical color categories differed from abstract five cardinal colors [五方色]. The diachronic dyes used during the Joseon Dynasty were safflower and Japanese alder bark for red, indigo leaves for blue, gromwell for purple, chestnut tree bark for brown. The representative dyes used in the late Joseon Dynasty were safflower and sappan wood for red, wild pear tree bark and Pentapetes phoenicea for yellow and orange, indigo leaves for blue, sappan wood and gromwell for purple, mulberry tree for brown, and Chinese ink for gray. Common dyes used both in Joseon and China were safflower and sappan wood for red, pagoda tree blossom for yellow, a combination of pagoda tree blossom (or Amur cork tree) and indigo leaves (or sediment) for green, indigo leavers or sediment for blue, sappan wood and hollyhock for purple, and a combination of indigo leaves and Galla Rhois for gray and black.

본 연구에서는 최근 새로운 활엽수 조림수종으로써 주목받고 있는 백합나무 제재목의 재질개선을 통한 부가가치 향상을 모색하고자 하였다. 이를 위해 이전 연구에서 삼나무의 재질개선 방법으로써 적용가능성이 확인된 $200^{\circ}C$ 내외의 고온 열처리방법을 적용하였으며, 백합나무 재색제어에 적합한 적정 열처리 조건 구명 및 열처리에 따른 재질변화 평가를 수행하였다. $200^{\circ}C$의 열처리 조건에서 백합나무 심 변재 사이의 재색차이가 줄어드는 경향을 확인하였으며, 이러한 경향은 처리시간이 증가함에 따라 더 크게 나타났다. 열처리재의 평형함수율이 무처리재에 비해 50% 정도 낮아 목재의 사용과정에서 나타나는 수분에 의한 성능저하를 예방할 수 있을 것으로 기대되었으나, 백합나무의 친환경 방부처리 기술로써 열처리의 적용 가능성은 삼나무에 비해 낮게 나타났다. 열처리재의 역학성능 변화는 삼나무와 거의 유사한 경향을 보였으며, 향후 백합나무의 용도를 개발하는데 있어서 이러한 물성 변화가 고려되어야 할 것이다. 열처리에 의한 물성변화의 원인을 규명하기 위한 미세구조 관찰 결과 에서는 특별한 변화를 확인할 수 없었으며, 추후 물성변화의 원인규명을 위한 추가적인 연구가 요구되었다.

This study was performed to investigate the effect of mordants on the dyeability colorfastness to light and to laundering and biological properties of mordanted and natural-dyed cotton and silk substrates. Natural red dyes were extracted from Caesalpinia Sappan L. (Sappan wood) and Rubia Akane Nakai (Madder) by boil water Five different compounds of Al, Cr, Cu, Fe and Sn were used as mordanting agents. The result of this study are sumarized as follows ; 1. In the of the fabrics mordanted and dyed with sappan wood K/S value increases and λmax shifts to the longer wavelength as mordant concentration increases. Color of the fabrics dyed with sappan wood and madder change to redder bluer and lighter after mordanting. 2. As the number of repetition of dyeing-mordnating process increase the color of the dyed fabrics tend to be redder bluer and darker. Mordanted dyes with Al and Sn make chroma increase. The quantity of mordant absorbed in the silk fabric increase as mordant concentration increase. More Fe is absorbed in silk than Cr is. 3. After being exposed to light the fabrics dyed with sappan wood and madder change to less red Fe and Cu mordanting yeild better colorfastness to light than others does. Natural-dyed fabrics exposed to light tend to be faded and whitened in CIELAB chromaticity co-ordinates. So we might trace back the original color of ancient faded fabrics by changes in color of natural dyes. 4. After washing the colors of natural dyes change to more blue, Fe and Cu mordanting give better colorfastness to wash than others do. 5. The soil-burial cotton is more susceptible to mildew and rot than the silk is. Antimicrobial activity of the natural-dyed cotton can be enhanced by Cu and silk can be enhanced by Cu and Cr mordanting respectively.

This study was carried out to manufacture wooden vessels by small diameter wood and wasted wood of Castanea crenata Sieb. et Zucc, which has been largely planted in southern area. We made spice set, tea box set, cookie vessel set, bowl set and accessory set. With the development of edged tools, the human species has been able to fashion wood to change and enhance its environment - one only has to look at the history of all cultures to see examples of wooden artifacts and structures. Even with the development of synthetic materials and the progress of automated, mechanized production of wood and wood products, the raw material is still processed by traditional methods to meet a never-ending demand for products made from this most desirable natural material. Chestnut wood has high added value and natural color grain and is very useful for wooden vessel. Thinned low grade trees can be used to produce wooden vessel. Therefore this result can promote thinning and produce good forestation.
