청국장 및 기능성분이 첨가된 청국장 추출물이 가지는 항혈전 관련 활성을 검정하였다. 흰 콩(Golycine max)과 검은 쥐눈이콩(Rhynchosia nulubilis) 청국장과 여기에 각각 녹차, 쑥이 첨가되어 제조된 청국장에 대해 in vitro에서 항산화 및 아질산염 소거 활성, 혈소판응집 억제 및 fibrin 분해활성을 측정하였고, 가장 우수한 시료에 대해 in vitro에서 혈전억제능을 시험하였다. 항산화 활성에 있어서 흰콩이나 검은콩 청국장 모두 녹차의 첨가량 증가에 따라 활성이 급격이 증가하는 경향을 나타내었으며, 쑥을 첨가한 경우에는 활성 증가율이 녹차에 비해 다소 적었다. 아질산염 소거 작용은 모든 시료에서 90% 이상 매우 높았으나 기능성분 첨가에 의한 영향은 크지 않았다. 혈소판응집 억제 활성을 조사한 결과, 녹차나 쑥을 첨가함에 따라 그 활성이 상당히 증가되었다. 특히 흰콩이나 검은콩 청국장 모두 $0.3{\sim}1.0%$의 낮은 농도에서도 녹차나 쑥의 첨가량 증가에 따라 활성 이 크게 증가하였다. 청국장 추출물의 fibrin 분해활성을 plasmin unit으로 환산한 결과, 흰콩보다는 검은콩 청국장의 혈전용해 활성이 약간 좋았으나, 기능성분 첨가에 따른 활성증가는 크지 않았으며 특히 쑥을 첨가한 경우는 저농도에서 활성이 상당히 감소하다가 농도상승에 따라 활성이 약간 회복되는 현상을 나타내었다. 시험군중 in vitro 혈전억제 작용이 가장 우수한 녹차 첨가검은콩 청국장에 대해 마우스를 이용한 in vitro 혈전유발 억제능을 조사하여, 녹차를 첨가하지 않은 것에 비해 1.5배 정도 억제능이 높음을 확인하였다. 청국장은 혈전용해뿐 아니라 혈소판응집 억제 및 항산화 기능 등에 의해서 혈전을 억제하는 것으로 나타났으며, 녹차나 쑥 등 기능 성분 첨가시 소량 첨가에도 매우 향상된 혈전억제 활성을 가진 청국장 제조가 가능함을 확인하였다. 구순 봉합수술 후에 구개부 (palatal segment) 의 면적은 계속 증가하였다. 치조골 면적과 거리 항목의 증가는 후방부에서 크게 나타났다. 이러한 결과는 PNAM치료에 의한 치조골 정형효과는 주로 전방부에서 발생하며, 치조골의 성장은 구순 봉합수술 후에 후방부에서 주로 발생한다는 것을 의미한다.물실험을 통해 증명이 되었으나 인간을 대상으로 한 역학적 연구는 아직 기대만큼 명료한 결과들을 제시해주지 못하고 있다. 그러나 IARC나 EPA모두 인체발암물질로 분류하였고 다양한 건강영향에 대한 증거들이 있는 것은 분명한 만큼 다이옥신 노출을 최소화하려는 노력을 게을리 해서는 안 될 것이다.EX>-RA투여로 인해 위내에 발생한 무위산증(achlorhydria)이 위암 발생의 위험을 높일 것이라는 기존의 가설을 뒷받침하는 결론이라고 할 수 있었다. Mies van der Rohe의 제자들이나 그로부터 영향을 받은 수많은 건축가들은 이러한 저항과 비판에 직면하게 되며 새로운 사고의 시대적 요구 앞에 고뇌하게 된다. 한국에서는 1978년 Mies van der Rohe의 제자인 김종성이 미국에서 서울로 돌아와 '서울건축컨설탄트'를 설립하며 본격적으로 Miesianism의 규범적 건축론을 설파하기 시작하였다. 이른바 시카고 국제주의학파의 건축전수라고 할 수 있는데 '서울건축컨설탄트'를 통하여 배출된 김종성의 제자들은 명쾌하고도 간결한 건축해법의 경험을 토대름대로의 정체성을 갖고자 노력하였으나 결국 다원적 가치를 요구하는 시대적 흐름 속에 혼란을 겪고 있는 것 또한 사실이다. 본 연구는 Miesianism의 기원을 밝히고 그것의 실수와 오류를 밝힘과 동시에 현대의 여러 가지 건축유형들과 비교하여 봄으로써 Post-Miesianism의 실체와 그 미래에 대하여 고찰하여 보고자 한다. 미스의 유산이라고 할 수 있는 Miesianism의 요체는 첫째, Schinkel로부터 이어받은 시대정신의 사명감,

This study was performed to investigate the effects of dried leaf powders and ethanol extracts of Perilla frutescens(perilla leaf), Artemisia princeps var. orientalis(mugwort) and Aster scaber(chamchui) on lipid metabolism and antioxidative capacity in rats. Forty-nine male Sprague-Dawley rats weighing 105.9$\pm$1.7g were blocked into seven groups according to body weigth and raised for four weeks with diets containing 5% dried powders of perilla leaf, mugwort and chamchui, or ethanol extracts from the same amount of each dried leaf powder. Food intake was higher in the control and chamchui powder groups than the other remaining groups. Weight gain was not significantly different among all experimental groups. Food efficiency ratio was highest in the perilla leaf powder group. Plasma total lipid and cholesterol, liver total lipid and triglyceride levels were highest in the perilla leaf powder group. In contrast, dried powders of mugwort and chamchui showed hypolipidemic effects in plasma and liver. Plasma and liver TBARS levels in both dried powder and ethanol extract groups of the three plants were lower than control. There was also no significant difference between corresponding dried powder and ethanol extract groups. Catalas and GSH-Px activities in erythrocyte and liver were not different among all the experimental groups. However, SOD activities were significantly different among the esperimental groups. In erythrocyte. SOD activiteis of all dried powder and ethanol extract groups except the perilla leaf powder group were higher than control, and the chamchui power group showed the highest activity among them. In liver, all the plant groups showed higher SOD activities than control. There was no significant difference between corresponding dried powder and ethanol extract groups. In conclusion, the dried chamchui powder and liver. All the dried plant powder and ethanol extract were effective in decreasing the TBARS levels of liver and particularly plasma. Among the antiocidative enzymes, SOD activity was most responsive to the experimental diets. All the plant groups showed increases in liver SOD activities and there were more increments in dried powder groups. Since the effects of dried powder groups on lipid metabolism were better than those of extract groups, it is plausible that the high dietary fiber level in dried powders was effective. Antioxidative effects were not significantly different between corresponding dried power and extract groups, and it was thought that ethanol extracts from three plants also had similar antioxidative effects as dried powderers.

Purpose: The purpose of this study was to investigate the effects of mechanical processing (tumbler, tenderizer, injector) and Ganghwa mugwort extracts (GM) on the stability of chicken Neobiahni during storage for 10 days at $4^{\circ}C$. Six treatments of chicken Neobiahni were manufactured with the following conditions: CON (tumbler), CON-A (tumbler + 0.2% GM), T1(tenderizer) T1-A (tenderizer + 0.2% GM), T2 (injector), T2-A (injector + 0.2% GM). Methods: The pH, POV, TBA, and sensory characteristics of chicken Neobiahni during storage for 10 days at $4^{\circ}C$ were measured in triplicate. Results: The pH of chicken Neobiahni was in the range of 6.00-6.37, with the highest values in the treatments containing GM (CON-A, T1-A, T2-A). Mechanical processing had no significant effects during storage. The color values (lightness, redness, and yellowness) did not differ significantly in all chicken Neobiahni samples, whereas storage time had a significant effect (p<0.05). The mechanical processing combined with GM appeared to effectively control the POV and TBA levels of chicken samples during the entire storage period. In addition, sensory evaluation ratings (color, juiciness, flavor, tenderness, and overall acceptability) were improved by the mechanical processing and the addition of GM. Conclusion: These results suggest that the combination of mechanical processing and Ganghwa mugwort extracts is a useful technique for retarding lipid oxidation in chicken Neobiahni.

This study was conducted to evaluate the allelopathic effect of aqueous extract of Ganghwa domestic mugwort (Artemisia spp.) on vegetables and its related allelo-chemicals. When the receptor vegetables, such as Chinese cabbage, lettuce, and red radish, were treated with aqueous extract obtained from Sajabalssuk (A. $sp^*I$), Ssajuarissuk (A. $sp^*II$) or Ssajarissuk (A. $sp^*III$), their germination rate, leaf number, plant height, and root length were restricted with increasing concentration of aqueous extract. Allelopathic effect was the highest in radish, than lettuce and Chinese cabbage in order. The growth of topplant were more inhibited then root growth observing in restriction of plant height, root length, and chlorophyll contents. The plant height, the root length of red radish were 53.3 and 61.2% and their fresh weights were 19.8 and 26.4% compared to those of controls, respectively. A. $sp^*III$ showed the highest allelopathic effect among the donor plants. In HPLC analysis, 7 phenol compounds were identified in A. $sp^*I$ and A. $sp^*II$, and, in A. $sp^*III$, and hydroxybenzoic acid and phenylacetic acid were further identified as allelochemicals. It is considered that their plant growths were variously inhibited by the amounts and types of allelochemicals in aqueous extracts. To increase the productivity of farm land after cultivation of mugwort, these results can be useful to select the following field crops.

This study evaluated the in vitro effect of medicinal plant extracts on ruminal methanogenesis, four different groups of methanogens and ruminal fermentation characteristics. A fistulated Holstein cow was used as a donor of rumen fluid. Licorice and mugwort extracts (Glycyrrhiza uralensis and Artemisia capillaris, 0.5% and 1% of total substrate DM, respectively), previously used as folk remedies, were added to an in vitro fermentation incubated with buffered-rumen fluid. Total gas production in Glycyrrhiza uralensis extract treatment was not significantly different between treatments (p<0.05) while total gas production in the Artemisia capillaris extract treatment was lower than that of the control. Artemisia capillaris extract and Glycyrrhiza uralensis extract reduced $CH_4$ emission by 14% (p<0.05) and 8% (p<0.05), respectively. Ciliate-associated methanogens population decreased by 18% in the medicinal plant extracts treatments. Medicinal plant extracts also affected the order Methanobacteriales community. Methanobacteriales diversity decreased by 35% in the Glycyrrhiza uralensis extract treatment and 30% in the Artemisia capillaris extract treatment. The order Methanomicrobiales population decreased by 50% in the 0.5% of Glycyrrhiza uralensis extract treatment. These findings demonstrate that medicinal plant extracts have the potential to inhibit in vitro ruminal methanogenesis.

This study was conducted to identify allelopathic effect of Ganghwa domestic Artemisia spp., named Sajabalssuk and Ssajuarissuk, for various receptor plants including clover (Trifolium repens L.), alfalfa (Medicago sativa L.), lawn grass (Zoysia japonica Steud.), dandelion (Taraxacum platycarpum Dahlst.), and dahurianpatrinia (Patrinia scabiosaefolia Fisch. ex Trevir). Receptor plants were treated with the aqueous and essential oil extract of Artemisia plants. In consequence, their allelopathic effects were evaluated by measuring seed germination rates, seedling growth, and dry weights of the receptor plants. The seed germination and seedling growth of the receptor plants were inhibited by all treatments of both aqueous and essential oil extracts of the Artemisia plants, and, in addition, the inhibitory effects were increased according to the higher concentration. Among the donor plants, A. $sp.^*III$ showed most effective allelopathic effect. Comparing the alleopathic effect among the receptor plants, seed germination was most inhibited in lawn grass while inhibitory effect of seedling growth was comparatively higher in dandelion. Although inhibitory effects were comparatively lower, the allelopathic effects of Artemisia plants were identified in clover and alfalfa since the seedling growth of these plants were inhibited more than 70%. Thus, in result, Ganghwa domestic Artemisia spp. could be possibly used for weed control since natural products of the plants showed inhibitory effects on seed germination and seedling growth of various receptor plants.
