  • The purpose of this study was to manufacture colored Hanji for interior materials by combining color therapy and natural dyeing. To manufacture colored Changhoji for interior materials, seven species of dyestuff were selected as a results of preliminary natural dyeing. As mordants, 0.5% $AlK(SO_4)_2{\cdot}12H_20$ and 0.5% $Cu(CH_3COO)_2{\cdot}H_2O$ solution were used respectively. To estimate natural dyeing properties of Changhoji, the value of $L^*,\;a^*,\;b^*$ and Munsell HV/C were measured by spectrophotometer. The super eight colors produced as follows; red from safflower, orang from goldthread and gardenia, yellow from turmeric, green and turquoise from indigo and pagoda tree flower, violet and magenta from sappanwood, and blue from indigo.

  • Functional healthy drinks were processed with freeze dried powders of ethanol extract from of defatted safflower (Carthamus tinctorious L.) seed cake and some useful components of the drinks were investigated. Yield of freeze dried powder was the highest as 8.42% when it extracted with 60% ethanol (60% EFDP). Each drink contained 0.02% of freeze dried powder and ranged 10.6∼13.8% of soluble solid, 2.90∼3.68 of pH, 0.10∼0.83% of titratable acidity. ‘L’ value of drink-I (DSD-I) was the highest as 94.82$\pm$2.45, ‘b’ and ‘a’ value of drink-V (DSD-V) was highest as 27.15-2.65 and 28.67$\pm$2.69, respectively. Major free sugars of drink were 6015.3∼7918.2 mg% of glucose and 1511.4∼2091.0 mg% of sucrose. The content of citric acid was the highest as 179.2∼981.3 mg%. The content of total phenol in 60% EFDP was 99.17 mg% and that of drink-II(DSD-II) and DSD-V was 307.84 mg% and 224.06 mg%, respectively. Total flavonoid was contained as 50.29 mg% in 80% ethanol extract (80% EFDP) and 125.20 mg% in DSD-V. N-[2-(5-hydroxy-1H-indol-3-yl) ethyl] ferulamide (serotonin-I) was determined as high as 18.81 ppm in 80% EFDP and ranged 2.42∼2.89 ppm in drinks. N-[2-(5-hydroxy-lH-indol-3yl)ethyl]-p-coumaramide (serotonin-II) was determined as 30.17 ppm in 80% EFDP and ranged 3.79∼4.59 ppm in drinks. Acacetin, flavonoid compound were 9.83 ppm in amyloglucosidase hydrosis + 60% ethanol extract (A + 60% EFDP) and ranged 0.98∼1.26 ppm in drinks. Electron donating ability (EDA, %) was measured and compared with 100 ppm BHA as chemical antioxidant. EDA was 93.97$\pm$2.21% in A+60% EFDP, 94.79$\pm$2.26% in DSD-I, 94.69$\pm$1.37% in DSD-II, and 93.83$\pm$1.49% in BHA. DSD-II added with hot water extract solution from Korean ginseng and safflower yellow pigment recorded the highest sensory score.

  • Methyl Bromide that was used as fumigation gas turned out to be the substance of destroying the ozone layer. For that reason, at the Montreal Protocol in 1987 the use of methyl bromide was forbidden starting 2005 in the advanced country. Also according to the 2007 Bali Protocolly methyl bromide is expected to be forbidden and therefore the purpose of this study is to find out the effects of substitution fumigation gas (Ethylene Oxide+HFC 134a, Methyl Iodide, Cyanogen and Argon) on the metal(silver, copper and iron), wood(oregon pine), pigment(yellow, red, blue, white and black), textile(hemp, ramie, jute, silk1 and silk2 / indigo, safflower and cork) and paper. After the fumigation test, ethylene oxide+HFC 134a did not have changes in the weight and color of the material itself before and after the experiment. On exterior alteration, color change occurred partly on paper and metal. Also, in most materials color change extent was 0.5 to 1.5 on the average and showed scanty difference. The materials after the fumigation test with methyl iodide did not show weight changes after the test. However, color changes more than 1.0 was shown in most of the materials especially in dyed textile material. In blue pigment, the discoloration on the surface could be seen by naked eyes. Fumigation test with cyanogen gas did not show weight changes and discoloration is more than 1.5 before and after the test. The weight changes of test materials with the argon gas was decreased about 3 to 6%. It can be observed that discoloration on paper was generated. Color changes can be seen on jute dyed with safflower and cork for two weeks with argon gas and the extent was 6.3 and 6.0.

  • The purpose of this study is to analyze on the textile used for book covers of "Gukgiboksiksoseon" and "Boepboksajeolboksaek", and slipcase of these books kept in the Oryundae Korean Martyrs Museum in Busan. These records are estimated to be written by Gyeongbin Kim(1831-1907), who was a royal concubine of 24th King Heonjong (reign 1834~1849) of the Joseon Dynasty. The cover textile of slipcase and two books are investigated to be silks by the FT-IR. The cover textile of slipcase is flower patterned satin with silver thread and the cover textile of two books are green and red with Su characters and bat patterned satin. The blackish part of pattern of slipcase is investigated by silver thread by FE-SEM-EDAX. Moreover, by the dye analysis, berberine, brazilin, and carthamin are detected from the cover textile of "Boepboksajeolboksaek". It is indicated that it was dyed with an amur cork-tree, a sappanwood, and a safflower. And rutin which is the main dyestuff of the sophora flower of the pagoda tree was detected from the yellow thread of the cover textile of slipcase.
