  • This study was conducted to develop recycle revegetation methods for the restoration of the steep slopes by using fresh wood chip from construction sites. In general, the fresh wood chips can be used as soil media for the restoration works, because they can increase infiltration of rainfall and give enough porous to breathe and elongate for the root growth as well as economic value. The experiment was carried out to compare the effect of fresh wood chips from different mixing with soil, organic material and macromolecular compound which used for slope restoration works conducted by Hyunwoo green(Ltd.). The main results by monitoring for two years are summarized as follows; 1. The soil media made with low percentage of fresh wood chip covered quickly by herb plants. Especially, the soil mixture Type C (wood chip 20%) showed 80 percent ground coverage within two months after seeding. 2. The soil mixture type E (wood chip 40%) and type F (wood chip 50%) which contains more fresh wood chips than soil type C was under 30 percent ground coverage because wood plants are germinated well. If the restoration works aims at making forest, then the soil type E and F would be recommended than using soil type C. 3. Among the woody plants, Ailanthus alfissima, Pinus rigida, Pinus densiflora, and Albizzia julibrissin showed high percentage of germination rates and vigorous growth. In case of shrubs, Lespedeza cyrtobotria and Indigofera pseudo-tintoria scored high percentage of germination rates. 4. In native plants, Chrysanthemum indicum, Artemisia princeps, Lutos corniculatus and Imperata cylindrica showed high percentage of appearance. In case of introduced herbs, Coreopsis lanceolata, Coreopsis tinctoria and Oenothera oborata grew so vigorously. 5. The soil types which including fresh wood chips over 30-40 percentage showed the most diverse plant composition and the most effective germination rates and growth pattern with woody plants. 6. This works to develop recycle revegetation methods using fresh wood chips need more efforts for monitoring the exact effect of fresh wood chips as the soil media.

  • This study was designed to observe the effects of the feeding Platycodon grandiflorum, Codonopsis Ianceolata, perilla oil and safflower oil on the fatty acid composition in serum and liver of dietary hypercholesterolemic rats. Experimental groups mixed with 5% cellulose +10% lard (group 1, control group), 2% cholestyraemine +10% lard (group 2), 5% C. ianceolata+ 10% perilla oil (group 3), 5% P. grandiflorum+10% perilla oil (group 4), 5% C. ianceolata+10% safflower oil (group 5) and 5% P. grandiflorum+10% safflower oil (group 6) were administered to the male rats of the Sprague Dawley for 3 weeks. In the fatty arid compositions of serum total fatty arid, phospholipid, triglyceride and cholesteryl ester, the linoleic acid content was most in the PUFA and it was major fatty acid. Particularly, the other components except the phospholipid fraction in serum lipids were influenced by the fatty acid composition of the test lipids from the fact that linoleic acid content was remarkably more in the groups 5 and 6. In the fatty arid compositions of liver total fatty acid, phospholipid, triglyceride and cholesteryl ester, the linoleic acid content was more in the PUFA and so it was major fatty acid. Particularly, the arachidonic and eicosapentaenoic acid contents of phospholipid fraction in liver lipids were rather more. from the above research, fatty arid composition of serum and liver lipid components were influenced by the fatty acid composition of the test lipids from the fact that linoleic acid takes up the highest percentage.

  • Associative heterotrophic nitrogen fixing bacteria were identified by immunodiffusion method in the histosphere of Planta-ginaceae, Caryophllaceae, Gramineae, and two types of rice cultivars. Twenty four strains associative heterotrophic bacteria with high ARA (more than 10nmole/tube/hr) were isolated from the histosphere of grasses and rice.* Those strains were related with 8 species of Azospirillum, 11 species of Pseudomonas, 2 species of Klebsiella and 2 species of Agrobacterium. Among them Azospirillum sp. and Pseudomonas sp. were predominant in histosphere of grasses and rice cultivars. From the histosphere of Oryza sativa, and Sagina maxima, the strains of Azospirillum, Pseudomonas, Klebsiella, and Agrobacter were identified while Pseudomonas was identified from Ischaemum anthephoroides, Plantago lanceolata, Miscanthus sacchuriflorum, and only Azospirillum was identified from Zoisia sinica, respectively. Associative nitrogen fixing heterotrophic bacteria were more abundant in the histosphere of Oryza sativa and Sagina maxima than that of other grasses grown in saline and reclaimed saline paddy soil.

  • Ecological studies on the effect of an accidental fire on the composition of the post-fire vegetation in relation to the productivity system were made at the burned site on Mt. Samak located at Duckduwon-Ri, Sumyun, Chun Sung-Kun, Kangwon-Do, the same plots used in the previous study carried out in 1967. The result are summarized as follows. 1. In the productivity system, the standing crop measured was as follows; Carex Lanceolata var. Nana, Miscanthus purpurscens etc. were contained in the herbs and their individual number was larger than that of the woody plants. (Table 1). In the woody plants, Quercus Acutissima was the most abundant, showing larger number of tree than Quercus dentata. The S.D.R. value of the family Poaceae was the highest among the herbs and in the test plots, it was 4 times larger in number than in the controlled plots. (Table 3, Fig. 4, 5). 2. In the unburned sities, 5 dominant species were selected and by calculating their S.D.R., it was shown that woody plants, S.D.R. is 4.43 while it is 11.52 with herbs. (Table 4, Fig. 6). 3. When making comparisons with the standing crop on the higher around, it was found that the test plots had 522.45 gm more than the controlled and 1470. 53gm more than those on lower ground. These results were considered to indicate that high temperature caused by fire resulted in the increase of germination rate of seeds as it was seen in the previous study and it further stimulate the growth of the perennial plants. (Table 6, 7) 4. In the number of species, the standing crop was increased in the order of Genus Miscanthus and Genus Carex. and in the woody plants Genus Lespedeza was increased in the standing crop. 5. It was found that in the rest plots, total summed height was greater by about 6000cm than that in the controlled plots. 6. In conclusion, the forest fire gave a great loss to tall trees and woody plants burning them together with unmatured seeds. In the succession of the 2nd year it was considered that the growth of the perennial plants had been stimulated on the barned sites.

  • Nationally designated Cultural Properties 'Scenic site No.12 Maisan Mountain, Jinan' designated areas and some protected areas, and taking into account the dynamics of naturalized plants causing problems, we will restore the original vegetation scenery of Mt. Maisan. The results of this study are as follows. A total of 76 families, 192 genera, 286 taxa, and inland and inhabited areas, 76 and 138 genera and 163 taxa were identified in the areas of Ammaibong. The total number of naturalized plants identified in this study area is 28 taxa total, which corresponds to 7.1% naturalization rate(NR) among the vascular plants of all 395 taxa, and the urbanization index(UI) corresponds to 8.4% of the 333 taxa of Korean naturalized plants. Ecosystem disturbance plants identified in the survey area were Ambrosia artemisiifolia 1 taxa. The naturalized plants controlled and managed by separate anthropogenic vegetation management within the designation and protection area of Maisan scenic place are three species of herbaceous Rumex acetosella, A. artemisiifolia and Festuca arundinacea. It was identified as a breed. Indigofera bungeana and F. arundinacea communities around the stairway and Amorpha fruticosa, I. bungeana, A. artemisiifolia and Amaranthus patulus of the top of Am-Maibong were selected as the first priority sites for exclusion of exotic species in Maisan area and target naturalized plants species to the Ammaibong peak. In addition, R. acetosella community around the temple was suggested to be removed first to preserve endemic species. For the restoration of vegetation, we suggest that Stephanandra incisa, Spiraea blumei, Weigela subsessilis, etc. should be planted after removal of I. bungeana, and F. arundinacea, C. lanceolata, Carex callitrichos var. nana.

  • It was confirmed that complex fermentation (CF) was more efficient than single-strain fermentations in inducing changes in the contents of phenolic compounds of Maclura tricuspidate and Pyrus Montana Nakai. A mixture of Maclura tricuspidata, Pyrus montana Nakai, Platycodon grandiflorum and Codonopsis lanceolata were fermented in CF using Aspergillus shirousamii (koji), yeast, and lactic acid bacteria (LAB) for 24 days, and the pH, °Brix, total acidity, anti-oxidant activity, polyphenol content, nitric oxide (NO), and Western blotting of inducible nitric oxide synthase (iNOS), cyclo-oxygenase-2 (COX-2), and tumor necrosis factor-𝛼 (TNF-𝛼) of the sample were determined. There was no significant change in pH and total acidity. °Brix significantly decreased from day 6 onwards. HPLC confirmed that the concentrations of chlorogenic acid, 4-hydrobenzoic acid, vanillic acid, and caffeic acid significantly increased from day 18 during the fermentation. Additionally, DPPH, ABTS radical scavenging activity, total phenol, and total flavonoid were confirmed to be increased until 18 days. NO was significantly inhibited from day 6, along with significant inhibition of iNOS, COX-2, and TNF-a. In conclusion, this study confirmed that CF of low-use (or underutilized) wild vegetables enhances phenolic compounds. It effectively suppresses NO, iNOS, COX-2, and TNF-𝛼, markers of inflammation-related pathogenesis. Altogether, our results suggest that CF of the above plants has a potential anti-inflammatory effect.

  • This research was performed to investigate the effect of aged Deodeok (Codonopsis lanceolata) water extracts on the levels of lipids in the serum of rats fed a high-fat diet for 10 weeks. Experimental groups were divided into basal diet only (BDG), high fat diet control (HFDCG), high-fat diet and 10% aged deodeok extract powder (HF10S), and high-fat diet and 20% aged deodeok extract powder (HF20S) groups. The levels of hematological variables were not significantly different among the four groups. Compared with the control group's serum total cholesterol level of $339.38{\pm}4.06mg/dL$, the levels of the HF10S and HF20S groups were significantly lowered to $225.38{\pm}5.44$ and $215.02{\pm}4.77mg/dL$, respectively. Compared with the control group's LDL-cholesterol leve of $64.91{\pm}3.67mg/dL$, the LDL-cholesterol levels of the HF10S and HF20S groups were significantly lowered to $54.16{\pm}3.46$ and $46.14{\pm}1.79mg/dL$, respectively. Also, compared to the control group's serum triglyceride level of $103.07{\pm}13.2mg/dL$, the level of the HF20S group was significantly lowered to $48.25{\pm}11.52mg/dL$. These results suggested that dietary supplementation of aged deodeok extract does not have any adverse effect on the hematological variables, while improving the lipid content and reducing hepatic damage of the high-fat fed rats.

  • This study was carried out to classify vegetation structure on the deciduous forest at Namdeogyu area in Deogyusan National Park from May 2007 to September 2008 using the gradient analyses and phytosociological method. The vegetation was classified into Quercus mongolica community(Typical subcommunity, Rhododendron sehlippenbaehii-Q. mongolica subcommunity, Carex lanceolata-Q. mongolica subcommunity), Q. Serrata community(Typical subcommunity, Q. variabilis -Q. serrata subcommunity, Carpinus laxiflora - Q. serrata subcommunity), C. laxiflora community, Fraxinus mandshurica community and Corn us controversa community. Ecological characteristics such as species composition, layer structure, vegetation ratio, and the distribution of individual trees by DBH(diameter at breast height) were significantly different among communities. The order of important value of the forest community with DBH 2cm above plants was Q. mongolica(67.8), F. mandshurica(44.8), Q. serrata(27.5), Acer pseudo-sieboldianum(17.0), C. controversa(l5.9), F. sieboldiana(l1.5), R. schlippenbachii(11.0), C. cordata(11.0), Styrax obassia(10.9), Magnolia sieboldii(10.4) and C. laxiflora(9.8). Distribution of DBH of Q. mongolica had a formality distribution, suggesting a continuous domination of these species over the other species for the time being. In contrast, F. mandshurica appeared limited to the valley of the sheet and a higher frequency of young individuals, suggesting a continuous domination of these species the development of a climax forest terrain. Q. serrata had a higher frequency of young individuals and middle individuals, suggesting a continuous domination of these species over the other species for the time being in contrast. This study examined the correlation between each community and the environment according to DCCA ordination. The Q. mongolica community predominated in the highest elevation habitats which had many C.E.C and T-N. F. mandshurica community predominated in the highest elevation habitats which had many Moisture and EX-Cation. The Q. serrata community and C. laxiflora community mainly occurred in the low elevation habitats which had few C.E.C and T-N. The C. controversa community appeared on the park in the middle habitats.
