Cotton and ramie fabrics were dyed with artemesia and gardenia dyeing solutions. The chroma values of the fabrics dyed with gardenia were higher than that of artemesia. The ramie fabrics dyed with gardenia showed higher chroma values than the cotton fabrics. The colors of fabrics were deeper in shade but their chroma values were improved no more by repetition of dyeing process in artemesia dyebath. The two ways of dyeing processes were carried out. In the first wan, each fabric was dyed in 5 different concentration(1∼5%) of gardenia dyebath to get the fabrics dyed in different shades. After then the gardenia dyed fabrics were dyed again in the artemesia dyebaths. In the second way, the 5 fabrics were dyed in different shades by repetition of dyeing process in artemesia dyebath. After then the artemesia dyed fabrics were dyed again with the gardenia dyebaths. When the artemesia dyeing process was added on the fabrics dyed in five shades with gardenia, the color differences between five samples were slight. But when gardenia dyeing process was added on the fabrics dyed in five shades with artemesia, the samples showed different hue of colors between yellow and green of Munsell color circle. Like almost of fabrics dyed with Plants materials, the colorfastness to light and laundering of the dyed samples were poor But the colorfastness to drycleaning was good.

The objective of the study was to investigate skin temperature responses of Hanbok when it was worn. Two healthy females(average 21 years, 155cm and 60kg were exposed to a climatic chamber(Room Temp. $21{\pm}1^{\circ}C,\;52{\pm}2%R.H.$, 0.15m/s). During the experiment, rectal temperature, skin temperature of 9 areas, clothing microclimate, subjective sensation were measured. Chima and Jogory to be made of silk nobang(SN) or Ramie were worn for summer. Polyester(P) Chima and Jogori(R) could be wort for spring and autumn. For winter, silk Chima, Jogori(S) and Durumagi(D) were commonly worn. Rectal temperature was high in order of naked(N), R, SN, P, S, D. However Mean skin temperature was reversely high in order of D, S, SN, R, P, naked. In naked, skin temperature was high in order of head, trunk upper extremity and lower extremity. But on wearing of Hanbok, it was the highest at the chest except head regardless of kinds of clothing ensembles. Skin temperature of upper arm was secondly highest on wearing the silk ensemble and the Durumagi ensemble, but skin temperature of buttock was secondly highest on wearing the silk nobang ensemble and the ramie ensemble. Skin temperature on wearing the silk ensemble was generally higher than those on other clothing ensembles. Local and mean skin temperatures on wearing the silk ensemble and the Durumagj ensemble were generally higher than on other clothing ensembles. Heat resistance of the fabric might have affected on the local skin temperature.

To develop natural dyeing materials from the unused plant materials, we had several dyeing experiments to investigate the optimum conditions of dyeing fabrics with the dyebath extracted from wisteria. Dyeing experiments were done under different dyeing conditions of dyeing temperature, pH of dyebath, dyeing time, concentration of dyebath and mordant treatment which were treated after dyeing. Experimental fabrics were silk, wool, cotton, ramie and hemp. Color difference(ΔE) and Munsell's HV/C of the dyed fabrics and color fastness of silk and cotton fabrics to dry cleaning, washing, rubbing, perspiration and light were measured. In silk and wool fabrics(non mordant, dyeing time-20min), color differences increased in case of dyeing temperature of $100^{\circ}C$, but in cotton, ramie and hemp fabrics, color differences did not increase. Without mordant treatment, color differences of all experimental fabrics were about 10-20, so in wisteria dyeing mordant treatment was necessary. Color differences were increased by the mordant treatment; the color of dyed fabrics with Al mordant is dull yellow, Cu mordant is gold and Fe mordant is olive tone. Color difference was not affected by pH of dyebath in all experimental fabrics. On the whole, the color fastness of dyed silk and cotton fabrics were good, but color fastness to washing and perspiration in Fe mordant was weak and improved in Cu mordant.

Effect of the pH condition was examined on extraction and dyeing of the yellow and red dyes of safflower. Absorption of dye solution extracted from safflower was changed by pH of solvent. In the case of yellow dyes, cotton and ramie weren't dyed regardless of pH of dye bath, but silks were significantly dyed at pH4. Raw silk showed better dyeability than refined silk. In the case of red dyes, cotton and ramie absorbed red dyes selectively, but silks absorbed yellow dyes more significantly than red dyes. Efficiency of extraction and dyeing of yellow dyes in acidic range were find out higher than that in neutral range. Red dyes was effectively extracted at pH11 and dyed at pH6.

β amyloid protein (Aβ) plays a critical role in the pathogenesis of Alzheimer's disease (AD) and possibly in Aβ-induced mitochondrial dysfunction and oxidative stress. Aβ can directly cause reactive oxygen species (ROS) production. Overproduction of ROS is considered to be involved in the pathogenesis of neurodegeneration of AD. Here, we investigated 9 kinds of ramie (Boehmeria nivea, (L.) Gaud., BN; hereafter denoted as BN) for their protective action against oxidative stress in a cellular system using C6 glial cells. We observed loss of cell viability and high levels of ROS generation after treatment with hydrogen peroxide (H₂O₂) and Aβ_25-35. However, treatments with BN extracts led to an increase in cell viability and decrease in ROS production induced by H2O2 and Aβ25-35. In particular, the extracts of BN-01 (seobang variety from Seocheon) and BN-09 (local variety from Yeonggwang) showed excellent anti-oxidative properties. This indicates that BN extracts could prevent neurodegeneration by reducing oxidative stress in cells.

As UV radiation to the earth increased over recent years, many adverse effects of UV radiation have been reported. There are needs to develop UV-protective apparel and accessaries to protect skin from these harmful effects. Cellulose is one of the most frequently worn fiber during summer time. However, celllulose shows very low UV-protective property especially in case of thin and low fabric content. In this study, UV-protective cellulose textiles were developed using chiotsan mordanting and green tea dyeing. The repetition effect of chitosan and green tea treatment were focused. Three different cellulose fibers, cotton, linen, and ramie, were used for this study. All chitosan mordanted and green tea dyed fabrics showed increases in UV-protective property. The color of fabrics tended to darker as the numbers of mordanting process and green tea dyeing increased. UV-protective property did not increase significantly upon the repetition of mordanting and green tea dyeing treatment except ramie fabric. UV protective property was persisted upon washfastness test in all three cellulose fiber types.

모시풀의 생장촉진을 위한 생장조절제의 적정 살포시기, 회수 및 농도를 알아보기 위한 시험결과를 요약하면 다음과 같다. 1. 모시풀의 생장점에 Gibberellin을 살포하면 줄기의 신장에 효과가 켰으며 경장 50cm 때의 1회 살포에 비하여 경장 50및 100cm때의 2회, 50, 100 및 150cm 때의 3회로 살포회수가 많을수록 그 신장도가 켰으며 생육초기보다 후기살포가 더욱 효과적이었다. 2. Gibberellin 농도는 50ppm 보다는 100～300ppm액 살포에서 줄기의 신장이 뚜렷하였으며, 이는 절간장의 신장에서 연유되었고, 절수의 증가는 거의 없었다. 3. 어느 농도에서나 1회 살포의 경우는 엽의 생장도 다소 좋아지는 경향이나, 2회, 3회로 살포회수가 많고 농도가 높을수록 오히려 엽의 생장에 저해를 받는듯 하였다. 4. 섬유수량은 Gibberellin 100ppm 3회 살포의 경우 가장 다수였으며 섬유비율에 있어서도 무처리구의 4.6%에 비하여 5.3%로서 가장 높았다. 5. Atonic은 모시풀의 줄기신장 효과가 Gibberellin에 미치지 못하였으며, 생장조절제 처리는 모시풀의 인피섬유의 발달에도 효과가 있는 것으로 생각되었다.

We can study and judge the costumes of the Three Kingdom period through an ancient tomb murals and various burial mound(clay) figures, however, it is quite difficult to search for costumes of the Goryeo period ($960{\sim}1392$), because dresses from this era were rarely found, related antiquities are limited and hard to survive. This is the reason why people say that the Goryeo Dynasty is the period of undiscovered era for its history of costumes in Korea. Fortunately, these days, there are various kinds of buddhist statues discovered with its burial accessories such as costumes and dyed fabrics of the Goryeo era. Through these, we can glimpse through the Goryeo cloths and develop our researches on this field. In addition, a man called Seo Geung(서긍, the Chinese scholar Xu Jing) wrote a book in the 12th century about peoples lives in Goryeo and in this book, there are few documents about the people's costumes which help us to understand the period's traditional dresses. In this paper, we will look for the traditional costumes which were formed and developed through people's lives in Goryeo, using remains from various burial accessories in buddhist statues as well as the documents related to the costumes written in ${\ll}$Goryeosa 고려사${\gg}$. Moreover, costumes of a period usually developed and influenced by the atmosphere of people's lives both economically and mentally, therefore, in this study, we will especially focus on the dresses of the bureaucratic officials and their wives, who led comfortable lives and latitude of mind. Through the records, like Silla, Goryeo exported Sehjeo(세저) and Sehjoongmapo(세중마포) to China. And we found out that Silla's skillful weaving techniques of hemp and ramie cloths were succeeded to Goryeo. According to above facts, Goryeo people made clothes with various kinds of fabrics such as, different sorts of silks, ramie, hemp cloths and cottons. They also have very skillful manufacturing techniques for certain textiles. Their official robes were generally influenced by Tang and Song Dynasty, but, like ordinary people, we found out that the government officials also wore baji(pants) and a jeogor(jacket), which were traditional costumes since the Unified Silla Kingdom with various coats. Especially, women's costumes such as jeoksam(unlined summer jacket) and hansam(한삼), which are sort of jeogori(jacket), baji(pants) and chima(skirts) were made of various kinds of silks and ramie cloths, that were generated from the Goguryeo Kingdom, with jikryeongpo(a long jacket and striped skirt).
