The purpose of this study is to scientifically proof possibility of development of natural dye which has antimicrobial activity with Chelidonium majus var. asiaticum. For that silk fabrics dyed with Chelidonium majus var. asiaticum extracts were tested for anti-microbial activity. Bacterials used for test of anti-microbial activity were Staphylococcus aureus ATCC 6538, Klebsiella pneumoniae ATCC 4352 and Trichophyton mentagrophytes IFO 5466. The results of experiment were as follows ; 1. The more the number of times of dyeing increase the more value of K/S increased. 2. Reduction of bacterium against Staphylococcus aureus ATCC 6538 of silk fabrics dyed with Chelidonium majus var. asiaticum extracts was 99.9% without reference to the number of times of dyeing. 3. Reduction of bacterium against Staphylococcus aureus ATCC 6538 of silk fabrics dyed with Chelidonium majus var. asiaticum extracts was 99.9% after irradiation of 20 hour without reference to the number of times of dyeing. 4. Reduction of bacterium against Staphylococcus aureus ATCC 6538 of silk fabrics dyed with Chelidonium majus var. asiaticum extracts was over 94.8% after dry cleaning. As above silk fabrics dyed with Chelidonium majus var. asiaticum extracts were acquired a high anti-microbial activity against Staphylococcus aureus ATCC 6538.

This study was conducted to investigate the effect of fermentation on biological activity of Chelidonium majus var asiaticum and to screen effective starter culture strains. Antibacterial activity against to Staphylococcus aureus, Listeria monocytogenes and Salmonella gallinarum and antioxidant activity as free radical scavenging activity by using DPPH were tested. Total six starter culture strains, two of Lactobacillus brevis, one of Lactobacillus plantarum and three of Saccharomyces cerevisiae were used. Plant extract was prepared after fermentation by using ethanol. All strains showed normal growth in viable cell counts of fermented cultures and L. plantarum showed the highest cell growth significantly (p<0.05). In antibacterial activities of extracts, the activity was found only in the extract from the fermentation using L. plantarum. In antioxidant activity, the highest activity was shown in the fermentation using L. plantarum significantly (P<0.05). Newly produced spots in two of three elution systems on TLC-DPPH test were detected in the fermentation using L. plantarum.

The purpose of this study is to examine the influence of the pigment characteristic and changes in dying conditions on the dying properties by extracting Chelidonium majus var. asiaticum using distilled water and ethanol as solvents. Changes in dying conditions include variations in dye concentrations, dyeing temperatures and time on dye uptake, and K/S Value was compared according to these changes. Additionally, color changes were observed through mordant. Ultraviolet-visible spectrum was used to investigate the pigment characteristic, and as a result, tannin was identified in distilled-water-extract, whereas berberine and chlorophyll were identified in ethanol-extract. In FT-IR analysis, tannin in distilled-water-extract was verified as hydrolyzable tannin. For ethanol extract, chlorophyll was verified through absorption band of C-H, which is aliphatic spectrum around $2920cm^{-1}$ and $2850cm^{-1}$. From GC/MS analysis, oil components as well as terpine compounds were detected in ethanol-extract, and this, in turn, brings expectation regarding functionality. When dying in silk, dye uptake increased as concentration of the extract increased, and the optimum dyeing temperature and time were $40^{\circ}C$ and 60 minutes respectively. Dyed fabrics' colors were all basically Y-series colors, and adjustment in brightness and revelation of khaki color were also available depending on the type of the mordant. Color fastness, except for washing fastness, was good in silk dyed with distilled-water-extract. Thus, it can be concluded that by selecting the right extracting method and by doing proper dyeing and mordant according to the needs, these dyed fabrics can be used as eco-friendly, functional clothing material.

The effects of oil unsaponifiables (8 species) and methanolic plant extracts (53 species) on the thermal oxidation of oils during 14 or 16 hour heating at $180^{\circ}C$ were studied by analyzing the fatty acid composition of soybean oil or cottonseed oil. All the unsaponifiables tested did not show any antioxidative activities on the thermal oxidation of soybean oil. However, among the 53 species of methanolic plant extracts, some species (Rheum undulatum L., Chelidonium majus L. var. asiaticum and Eugennia caryopyllata T.) showed very strong antioxidative activities on the thermal oxidation of cottonseed oil. The antioxidative activities of methanolic extracts of these 3 species on thermal oxidation of cottonseed oil during an extended heating period were also studied by heating cottonseed oils for 7 hours a day for 8 days at $180^{\circ}C$. The methanolic extracts of Chelidonium majus L. v. asiaticum and Eugennia caryopyllata T. greatly reduced both polymer formation and linoleic acid decomposition after the 8 day heating at $180^{\circ}C$. However, the methanolic extracts of Rheum undulatum L. was effective for the reduction of polymer formation, but not for the reduction of linoleic acid decomposition.

This study is carried out to make the environmentally affinitive porous planting block for revegetation and to make a effective program for greening plans. The summary is shown below. 1. In order to get stronger intensity and distribute proper porosity in the block for planting, the cements mixed with fine soil were used and the finer in soil grains gives the stronger in intensity of the cements. Use of the furnace slag cements instead of the portland cements showed relatively stronger in intensity of the block. The intensity of the block became stronger when the mixed ratio of the cements to soil is 5 : 1, but the pore space ratio was lower. The percolate pH of the portland cements after one month of treatment was 13.1 but the percolate pH of the furnace slag cements was shown lower. To mold proper porous planting blocks, the proper combination of additives such as the dehydrating agent, elastic agent and adhesives into the mixture of cements and soil gives better effectives. 2. After molding the porous planting blocks, it gave a better result when the grains of the filler made of peat moss, upland soil and compound fertilizer were smaller than 2 mm in size. Shaking of the filling materials also gave the better result, but it took more time and cost much more. Therefore, it was better when the filling materials were mixed with water first then flew down for stuffing. 3. It was necessary to cover with soil after seeding or planting on the porous planting blocks. The proper thickness of the soil to help root development and keep moisture is about 3~5 cm. 4. The plants for planting on the porous planting block were required stronger in the growth condition of their roots and their environmental adaptability. The average germination percentage and rate of Platycodon grandiflorum on the porous planting block were 88.8% and 85% accordingly and their rate is very uniform. The germination rates of Dianthus superbus var. longicalycinus and Taraxacum officinale were more than 50%. These grass species, Chelidonium majus var. asiaticum, Lysimachia mauritiana and Scabiosa mansenensis were the suggested biennial grasses in the planting area where exchanging of the seedling or nursery plants was not necessary because their germination rates were 59.3, 45.6 and 40.3% accordingly. Viola kapsanensis, Chrysanthemum sp., Taraxacum sp. and Iris ensata var. spontanea are the grass species that could be used by seeding for greening. However, the germination rate of Solidago virga-aurea var. asiatica, Aster scaber and Lythrum anceps were lower than 10%. The coverage ratio of Ixeris stolonifera is more than 80% after 60 days seeding and the root length of most of species are more than 10 cm except Iris ensata var. spontanea and Platycodon grandiflorum because their root developed thicker than other species.
