서산 용현리 마애여래삼존상(국보 제 84호)이 새겨진 암체는 층암절벽에 수직수평 방향으로 구조선이 매우 발달한 암체이다. 2007년 보호각 해체 후 상부 암체로부터 유입되는 낙수로 인하여 본존불 좌측에 생물학적 풍화가 진행되고 우측 보살상 상부에는 백화가 관찰되고 있다. 마애불상의 풍화를 저감시키고 훼손으로부터 미연에 방지하기 위한 조치로 건 습식세척으로 부재에 손상이 가지 않도록 오염물을 제거하고, 암체 상부에 L-30을 사용하여 물길을 설치하여 상부로부터 유입되는 낙수로 마애불상 표면이 오염되지 않도록 차단하였다. 또한, 마애불상 주변의 수목을 제거하고 정면부에 자생하는 잡목을 벌목하여 마애불상의 일조량을 증가시키고 통풍을 원활하게 하였다.
The experience of natural dyeing is expected to be effective in promoting health through good exercise, in giving emotional stability based on the functional aromatic components of the dyeing material, and in improving self-esteem and increasing positive experiences through the behavior of creation. A natural dyeing material easily found around us, artemisia has long been used in food and Oriental medicine and was recently found to contain antioxidative, anticancer, deodorizing, antibacterial, anti-obesity, and anti-diabetes substances through chemical analysis. It has also been reported that group reminiscence therapy using the fragrance of artemisia is effective in relieving pain and depression and in promoting ego integrity in the elderly population. This study aimed to make a comparative analysis of dyeability, washing fastness, and deodorization between Artemisia princeps, Artemisia iwayomogi, and Artemisia annua, all of which are considered to be healthful and functional dyeing materials, among about thirty domestic plants in the genus of Artemisia and to provide basic data concerning natural dyeing in mind-peace education for the silver generation. The fabric dyed and post-mordanted at $80^{\circ}C$ for 40 minutes showed the greatest surface color variation; in this condition, artemisia princes (32.29) gave the greatest color difference, followed by artemisia iwayomogi (31.07) and artemisia annua (26.17). While all the types of artemisia were excellent in washing fastness, dry-cleaning fastness, and rubbing fastness at the fourth- or fifth-grade, light fastness was at the third grade for artemisia princes, at the second to third grade for artemisia annua, and at the second grade for artemisia iwayomogi; therefore, artemisia princes was found to give better fastness than the other two types of artemisia. In determining functionality of the fabric dyed with artemisia, deodorization test also found that the fabric dyed with artemisia princes had 20% higher deodorization.
Dyeability of Indian natural dyestuffs to fabrics was investigated. Indian dyestuffs are more inexpensive than domestic dyestuffs purchased at oriental medicine stores. We studied the dyeability of madder, marigold, and pomegranate imported from India on cotton, silk, and wool fabrics. Dyebaths of a combination ratio of 80:20, 60:40, 50:50, 40:60 and 20:80 of madder and marigold, fabrics with orange colors were dyed. To evaluate the dyeability of dyed fabrics, K/S values, Munsell color values and CIE L, a, b, ${\Delta}E$ were measured. The dyeability of fabrics dyed in dyebaths of pH 4 and pH 7 were higher than pH 10. The dyeability in pH 4 was better than pH 7. Silk fabrics dyed with madder and marigold showed good dyeability and wool fabrics showed good affinity in madder dyebath and fair affinity in marigold dyebath. Cotton fabrics showed fair affinity in a marigold dyebath of pH 4 and pH 7. Cotton fabrics dyed with a 60:40 ratio of madder and marigold showed 4.76YR of Munsell color value. Silk Fabrics dyed with a 40:60 ratio showed 4.76YR and wool fabrics dyed with 20:80 ratio showed 5.57RY. The ratios produced the closest colors to 5.0YR of orange. This result indicated that marigold had a more powerful effect on cotton fabrics while madder was stronger on wool fabrics. Fading grades of washing colorfastness of wool and silk fabrics dyed in mixed dyebaths were higher than 3.5-4.0 and higher than homogeneous dyebaths. Staining grades of washing colorfastness of all dyed fabrics were between grades 3.5-5.0. Colorfastness to dry-cleaning was high as grades 4.0-5.0 in all of dyed fabrics. Colorfastness to light of dyed fabrics showed a fair grade of 3.5-5.0; in addition, wool fabrics showed lower grades than silk and cotton fabrics.
Contamination of soil by deicing salt is among the important environment problems due to their toxicity and negative impact to human health and the environment. One of the effective methods for cleaning the soil from deicing salts is desalination using soil amendment-phytoremediation continuum treatment. The purpose of this study was to determine how much of the pH, EC control and Ca2+, Na+, Mg2+, and K+ taken up soil amendments and Miscanthus sinensis, and to evaluate the effect of salt reduction and growth improvement as affected by soil amendment in high concentration of calcium chloride (CaCl2) deicing salts. Results indicated that the addition of soil amendments was decrease the EC and pH, also significantly reduce the leaching of Ca2+, Na+, Mg2+, K+, a chloride ions related deicing salts, compared to the control for CaCl2 10 g/L treatment. It also resulted in an enhanced plant growth and higher plant height, leaf length, leaf width, number of leaves, fresh weight and dry weight in Hydroball treatment + Miscanthus sinensis planting continuum treatment compared to the treatment that planted Miscanthus sinensis only. Therefore, we concluded that soil amendments might be attributed to an accumulation of deicing slats in the roadside soil, resulting in the improvement of Miscanthus sinensis growth.
A field study was conducted during the summer time of 2002 to determine compositions of volatile organic compounds (VOCs) emitted from vehicles and to develop source emission profiles that is applied to CMB model to estimate the source contribution of certain area. Source emission profile is widely used for the estimation of source contribution by the chemical mass balance model and have to be developed applicable for the target area of estimation. This study was aimed to develop source emission profile and estimation of source contribution of VOCs after application of the chemical mass balance (CMB) receptor model. After considering the emission inventory and other research results for the VOCs in Seoul, Korea, the sources like vehicle emission (tunnel), gas station (gasoline, diesel), solvent usage (painting operation, dry cleaning, graphic art), and gas fuels were selected for the major VOCs sources. Furthermore, ambient air samples were simultaneously collected from 09:00 to 11:00 for four days at eight different official air quality monitoring sites as receptors in Seoul during summer of 2001. Source samples were collected by canisters, and then about seventy volatile organic compounds were analyzed by gas chromatography with flame ionization detector (GC/FID). Based on both the developed source profiles and the database of the receptors, CMB model was intensively applied to estimate mass contribution of VOCs sources. Examining the source profile from the vehicle, the portion of alkanes of VOCs was highest, and then the portion of aromatics such toluene, m/p-xylene were followed. In case of gas fuel. they have their own components; the content of butane, propane, ethane was higher than any other component according to the fuel usage. The average of the source apportionment on VOCs for 8 sites showed that the major sources were vehicle emission and gas fuels. The vehicle emission source was revealed as having the highest contribution with an average of 49.6%, and followed by solvent with 21.3%, gas fuel with 16.1%, gasoline with 13.1%.
The purpose of this paper is to investigate the dyeability, antibacterial activity, and deodorization of cotton and silk fabrics dyed with extracted solution from Chrysanthemum boreale. The results are as follows: 1. The optimum conditions of dyeing temperature and time for the cotton fabrics were 90$^{\circ}C$ and 60minutes, while those of the silk fabrics were 60$^{\circ}C$ and 30 minutes respectively. 2. The K/S values of cotton fabrics were slightly higher than those of silk fabrics. The K/S values of both fabrics were slightly increased by mordanting with Cr but were decreased by mordanting with Cu and Fe 3. The colors of the cotton and silk fabrics changed from GY to Y. In both cases, the values of the fabric colors were lowered, and the values of the colors continued to be lowered with Cu and Fe. The chroma and color difference of both fabrics were high and were further increased by mordanting with Cu. 4. The fastness to dry-cleaning and rubbing of the cotton and silk fabrics was very good. The fastness to washing of both fabrics was good except when mordanted with Fe. The fastness to perspiration of both fabrics was fairly good, but the fastness to acid perspiration was poorer than that to the alkaline perspiration. The fastness to light of both fabrics was very poor. 5. The cotton and silk fabrics showed excellent antibacterial activity. Both fabrics mordanted with Cu showed perfect antibacterial activity. 6. The deodorization of the silk fabrics was very good, and that of the silk fabrics mordanted with Cu and Al was excellent, while the deodorization of the cotton fabrics was fairly good.
This study was carried out the effect of stability and color extract for it's condition in the curcuma L.. dyeing. The stability is to investigate the absorbance of the curcumin, one of the major yellow pigments and the stability regarding the effect of light, oxygen temperature and pH. The dyeing condition is compared the effect of mordanting condition and the best way to extract pigment and analysed through the color-fastness rating, color-difference value test. The main results obtained are summarized as follows ; 1.The best and proper solvent to extrect curcumin pigment was a ethanol and a distilled water. 2. The light effect indicated that the absorbances of solution in absence of ligh was more stable. 3. The oxygen(O2) effect to curcumin show-ed that the condition in the absence of O2 was more stable than that in presence of O2 4. The temperature showed that the absorbnace was best stable in4$^{\circ}C$ and less changed at $25^{\circ}C$ 5. The curcumin-etanol solution was stable in pH 2~4. 6. Generally color-fastness rating to silk, wool and cotton indicated that crocking C.F. and perspiration C.F. were more than 3rd grade and dry cleaning C.F. was more than 4th grade. But light color-fastness and washing color-fastness were very poor. 7. To make good color fastness, the mordan-ting treated group and the pre-mordant conditions were more effective than others 8. When compared with color-difference value test indicated that the silk was looks like more reddish and bluish color and than the wool and cotton were greenish and bluish. As a mordant, A(C2H4OH(COOH3) and D(K2Cr2O7)were more effective to make green-ish color in the silk and the reddish color was abtained by B(Al.K(SO4)2.12H2O) and C(FeSO4.7H2O).
The dyeability and antibacterial activity of fabrics dyed with lavender extract were analyzed. The results obtained are as follows. The surface color of all the dyed fabrics was tinged with green or yellow of a slight red tint. In the test results of dyeing colorfastness, the colorfastness to sunlight of the dyed fabrics which is both not treated with a mordant and treated with a K2Cr2O7 mordant was excellent with 4th grade of colorfastness. The others showed below 2nd grade. The colorfastness to laundry showed, as most of dyed fabrics were 4th-5th grade, relatively excellent results. The colorfastness to perspiration showed different results respectively according to the kind of both dyed fabrics and mordants. The colorfastness to crocking of the dyed both cotton and silk fabrics showed the excellent result of 4th-5th grade. The colorfastness to dry cleaning of all the dyed fabrics was excellent with 4th-5th grade. In the test results of antibiosis, the dyed fabrics of both cotton and silk didn't show the significant decrease rate for the fungus called Klebsiella pneumoniae. For the fungus called Staphylococcus aureus, the dyed cotton fabric showed the decrease rate of $98\%$ and the dyed silk fabric showed the decrease rate of $50\%$. For the fungus called Chaetomium globosum, the dyed fabric of cotton didn't show the significant antibacterial efficacy, but the dyed fabric of silk showed the significant antibacterial efficacy for the mold fungus called Aspergillus niger.
The research examines the characteristics of the sewing methods used for women's Jeogori in modern Korea. The results are following. In the 1920s sewing of shoulder parts was started, and in the 1930s sewing by hand had reduced by dissemination of sewing-machine, and in the 1940s the Som-jeogori declined by the matter of economic and sanitary issues. In the 1950s four-fold sewing emerged, and during the 1960s the gause-lined triple-layered Jeogori was in fashion, and in the 1970s the Ggaeggi-jeogori and much elaborated Jeogori became in vogue. The characteristics of the sewing methods are changed by following factors. First, the dissemination of sewing-machine in the 1930's enabled fast and precise sewing of Jeogori which reduced the rate of clothes mending and the production period. Second, by development of washing method, the dry cleaning became common, resulting cleaner washing and better preservation. Third, introduction of western clothes gave rise to modernized Han-bok which was changed into practical and simple one. Fourth, by the introduction of synthetic textile and industry development, Jeogori with no armhole line or right Seop line was made using wide selection of textiles. Fifth, in 1945~60s, women learned' good wife and wise mother' education and the use of sewing machine in school. The clothing lifestyle affected the sewing method's change, for example, clothes sewed strongly by sewing machine not to take clothes apart, and attaching button instead of Go-reum to save clothes.
The aim of study was to elucidate dyeability and antimicrobial and antifungal activity of silk fabrics dyed with Sophora Radix extracts according to different mordants. Dyes were extracted from Sophora Radix using ethanol. Then, silk fabrics were dyed with extracts two times by post-mordanting method in which the extract was 60%(owf), the mordant was 3%(owf), L.R was 1:20, the temperature was $60~60^\circ{C}$, the time of dyeing was 60min., and the time of mordanting was 60min. The dyeability was evaluated by surface color, K/S values and durability of dye. The skin microorganisms used in this study was S. sureus, B. subtilis, S. epidermidis, P. acnes, P. aeruginosa, E coli, A. niger, C. albicans and T. mentatrophytes. The results are as follows; 1. When mordants were added, K/S value of silk dyed was not improved much and surface color was 2.2Y to 8.8Y in H(hue) value which indicated greenish yellow to raddish yellow 2. The color fastness tests to light, perspiration, dry-cleaning, rubbing, and stain fabric washing show 4~5th degree which were valuated excellent. The color fastness to fade washing was improved to 3~4th degree by addition of $K_2CrO_7$ mordants. 3. Antibacterial activity of silk dyed using no-mordant as well as mordants was excellent on S. aureus, B. subtilis, S.epidermidis and P.acnes, but showed poor antibacterial activities on P.aeruginosa and E.coli such as gram negative baterials 4. Antifungal activity of silk dyed with ethanol extracts was good on A.niger, C.candida and T.mentagrophytes. Especially, on T. mentagrophytes there was no growth of fungus during 72 gous in silk dyed mordanting with $SnCl_2\cdot{2H}_2O$.
