  • Characteristics of Cheonggukjang with addition of different dropwort (Oenanthe javanica D.C.) powders were investigated. The selected strain, with proteolytic, amylolytic, and antimicrobial activity, was identified as B. subtilis RS-9, using 16S rRNA analysis. The Cheonggukjang was prepared with cooked soybean without dropwort (Control), 0.5% raw dropwort powder (DW0.5), and 1% raw dropwort powder (DW1), 0.5% steamed dropwort powder (SDW0.5), and 1% steamed dropwort powder (SDW1) were added, respectively. The changes in pH of Cheonggukjangs with addition of dropwort powder were lower than those of control during fermentation for 72 hr at $40^{\circ}C$. The total aerobes of the various Cheonggukjangs reached 8.88 (control), 8.82 (DW0.5), 8.70 (DW1), 8.85 (SDW0.5), and 8.75 (SDW1) log CFU/mL after fermentation for 72 hr at $40^{\circ}C$, respectively. The amino nitrogen and viscous substance contents of different dropwort powders added to Cheonggukangs were lower than those of control. The total polyphenol contents and ABTS radical scavenging ability of various Cheonggukjangs were increased by addition of dropwort powder and fermentation. The polyphenol contents and ABTS radical scavenging ability of SDW1 were $590.24{\mu}g/mL$ and 82.16% and showed the highest value among tested Cheonggukangs. The sensory quality of DW0.5 was higher in taste and overall acceptability, compared with other groups.

  • The removal rate of heavy metals from the wastewater, the accumulation and translocation of heavy metals in plants after transplanting, and the responses of water celery growth with different wastewater treatments were investigated to determine the potential ability of green-remediation with hydroponic culture of water celery. The removal rate and translocation of Cd, Cu, Ni and Pb from different wastewater to plants were compared with cultivation periods after transplanting. The removal rate of heavy metals from wastewater was different with each treatment but increased with growing periods of water celery plants. The removal rate of Cd, Cu, Ni and Pb in Artificial solution, Artificial solution+EDTA, Munmark industrical wastewater, Jungsun minewater is ranged from 22 to 73%, from 28 to 100%, from 13 to 92% and from 41 to 100% at 6 days after transplanting, respectively. The translocations of Cd, Cu, Ni and Pb from roots to shoots in Artificial solution, Artificial solution+EDTA, Munmark industrical wastewater, Jungsun minewater are ranged from 14 to 28%. 8 to 30%. from 28 to 45% and from 2 to 15% at 12 days after transplanting, respectively. In plant growth responses, it appears to be inhibited the plant growth over all treatments excepts for Munmark industrial wastewater in these glowing periods. Therefore the water celery might play a useful role in phytoremediation to clean up wastewater contaminated with Cd, Cu, Ni or Pb.

  • Ixeris sonchifolia Hance(Godulbaegi), Oenanthe javanica(Dolminari), Fagopyrum esculentum Moench(Buckwheat), Hizikia fusiforme(Seaweed Fusiforme) and Zingiber officinale Roscoe(Ginger) have all been used as one of the traditional remedies as well as food source. There are few studies However, on their immunomodulating effects have been reported. We previously reported that ex vivo supplementation of each of the Ish, Oj, Fem, Hf and Zor water extracts enhanced the splenocytes proliferation compared to the control group. In this study, the combined immunomodulative effects of a plant water extract mixture containing these five food sources(Ish+Oj+Fem+Hf+Zor) was compared to the individual effect of each. The production of cytokine(IL-1${\beta}$, IL-6, and TNF-${\alpha}$), secreted by macrophages stimulated with LPS or without, were detected via ELISA assay using a cytokine kit. After 48hrs of incubation with mitogen(ConA or LPS) stimulation, the mouse splenocyte proliferation in the experimental group had significantly increased at two different concentrations compared to the control group. The results of this study may suggest that the supplementing with a plant water extract mixture could regulate immune function by increasing splenocyte proliferation as well as enhance immune function by regulating the cytokine production capacity activated macrophages in mice.

  • This study was conducted to investigate pollutant loading, were quality and plant distribution of 8 streams which are tributaries of the Youngsan River. The nitrate reductase activity (NRA) and nutrient removall capacity of the most frequently occurring aquatic plants on streamside were also determined. As a result, the pollutant loading appeared to be correlated with the area of watershed, while the water quality was related to the land use pattern of each steam. The aquatic plants were distributed differently among the streams; Hydrilla verticillata - Potamogeton crispus, Numphoides peltata - Hydrocharis dubia and Polygonum thunbergii - Phragmites japonica were dominant at the Orye Chon, Jungan Chon, Whangryong River and Jiseok Chon, while potamogeton crispus - Lemma paucicostata, Zizania latifolia - Phragmites communis were dominant at the Youngam Chon and Munpyeong Chon. Persicaria hydropiper and Echinochloa crus-galli var. oryzicola were dominant at Kwangju Chon which was polluted with domestic wastewater. >From the measurement of leaf NRA for dominant species, the highest value of NRA was shown by the Polygonum thunbergii, followed by Oenanthe javanica > Phragmites communis > Zizania latifolia > Lemma paucicostata. The highest nitrogen and phosphorus removal capacity was found in Phragmites communis.

  • This study examines the effects of the Korean horticultural foods which are, by traditional wisdom, supposed to contain anti-aging substance. All twenty three kinds of plants are chosen as a sample for the experiment in which the content of three main anti-aging nutrients, -carotene, Vitamin C, and Vitamin E are respectively measured by Nilis, Colorimetric, and AOAC method. The result shows: among the samples, top six plants that contain the most -carotene content are high quality tea(Camellia sinensis), thistle(Cirsium japonicum Var.), Angelica keiskei, mulberry leaves(Morus alba l.), field horsetail(Equisetum arvensa), and carrot(Daucus carota), in order; top four for a Vitamin C contents are low quality tea, mulberry leaves, pine leaves(Pinus densiflora), and high quality tea, in order; top four for a Vitamin E contents are persimmon leaves(Diospyros mongolicum) tea, high quality tea, low quality tea, and pine leaves, in order. Drying or boiling process increases the content of -carotene and Vitamin E in high quality tea, dropwort(Oenanthe javanica), field horsetail, and wild aster(Ligularia stenocephala Marsumum et Koldzumi), while, in case of mulberry leaves, drying process lowers them. Vitamin C content strikingly decreases in heating and drying process.

  • This study was carried out to develop the technology of artificial floating island for the wild-life habitat at the reservoir of Korea University farm near Seoul. After the execution of an artificial floating island with 6 cells(each $3{\times}3m$), each cell was planted with 5 different species and one mixed of them, to the reservoir in 1999 through 2000. The monitored results were as follows; 1. Typha orientalis, Zizania latifolia and Oenanthe japonica were died back, but Phragmites communis, Phragmites japonica and Juncus effusus var. decipiens were well growing. 2. The limits of sinking water depth of the planting foundation were different with the plant species, that is, 40cm to the Juncus effusus var. dicipiens and 50cm to Phragmites communis. Accordingly the water depth should be kept differently with each species. 3. 33 species of fauna were monitored in the first year(1999) and 43 species in the second (2000) increasingly. 4. For the more wild-lives inducing to the artificial floating island, establishing the eco-corridor from the surrounding environment was needed.

  • Presently, aquatic plants are used for the water purification in inland water. This study was carried out to investigate the water purification effect of aquatic plants, Oenanthe javanica and Typha angustata, The experiment was conducted in outdoor flowing water was conducted for ten days, Water quality was measured in terms of water temperature, COD(chemical oxygen demand), SS(suspended solids), Total N, Total P. The results of field experimentation showed that hydraulic retention time was the earliest in July and August 2003, and there were not any particular changes of monthly water temperature in inflow water and outflow water. As we look at the changes taken place in inflow water and outflow water throughout the whole experiment period, the change of water quality in summer was salient, especially SS removal ratio showed distinguished change as $25\%$, when the pebble filter and aquatic were attached to it. The removal rate of COD, total N total P were $14,7\%,\;8\%\;and\;9\%$, respectively. In relating the length of water extension to the change in water quality, the water quality tended to get lower generally in proportion to hydraulic retention time.
