This experiment was carried out to figure out the CO2 biomass and the growth response of Chinese cabbage and radish grown under the condition of high temperature and high CO2 concentration to provide the information for the coming climatic change. Chinese cabbage and radish were cultivated in spring and autumn seasons under 4 treatments, 'ambient temp.+ambient CO2 conc.', 'ambient temp.+elevated CO2 conc.', 'elevated temp.+ ambient CO2 conc.', and 'elevated temp. +elevated CO2 conc.'. The 'elevated temp,' plot was maintained at 5 higher than 'ambient temp. (outside temperature)'and the 'elevated CO2 cone.' plot was done in 650 ppm CO2. The growth of spring-sown Chinese cabbage was worse than autumn-sown one, and was affected more by high temperature than high CO2. concentration. The CO2 biomass of Chinese cabbage was lower as 25.1-39.1 g/plant in spring-sown one than 54.8-63.4 g/plant of autumn-sown one. Daily CO22 fixation ability was not significantly different between spring- and autumn-sown Chinese cabbage as 1.9-2.9, 2.7-3.1 kg/10a/day, respectively. The CO2 biomass of radish were 87.4-104.6 /plant in spring-sown one and 51.3~76.4 g/plant in autumn-sown one. Daily CO2 fixation ability of radish were 6.2-10.1 kg/10a/day in spring-sown one and 4.6-6.9 kg/10a/day in autumn-sown one.

토양에 비료 형태로 투여한 셀레늄 농도와 처리기간이 마늘의 생육에 미치는 영향을 구명하고자 본 실험을 수행하였다. 셀레늄의 농도가 높고 처리기간이 길수록 생체중은 대조구에 비하여 감소하였다. 셀레늄의 처리농도가 높고 처리기간이 길수록 3주 후 셀레늄의 함량은 구보다는 엽초에 많이 축적되었다 그러나 처리 6주 후에는 구〉엽초〉뿌리 순으로 셀레늄의 함량이 높았다. 셀레늄 처리 후 토양에 잔류하고 있는 셀레늄의 함량은 대조구와 차이가 없었다.

The characteristics of odor and VOCs emitted from a sewage treatment plant was investigated to provide the basic informations in the design of odor and VOCs treatment processes. The sewage treatment plant which treated domestic wastewater only and consisted of a flow equalization tank, thicker, and sludge container was selected. Odor and VOCs sampled three times (June - July) at the temperatures ranging from 24℃ to 27℃ were analyzed by GC/MS and GC/FPD. Odors were hydrogen sulfide, dimethylsulfide, ammonia, and styrene. Among them, the main compounds were dimethyldisulfide (14.45~2,340.91 O.U.) and ammonia (18.51~16,520 O.U.). The order of odor dilution ratio and odor unit can be listed as follows : Sludge container ＞ Flow equalization tank ＞ Thicker. The main VOC produced from sewage treatment plant was benzenes, and the others were dichloromethane, toluene, ethylbenzene, m,p-xylene, styrene, 1,2,4,-trimethylbenzene, 1,3-dichlorobenzene, and 1,2-dichlorobenzene. The concentration of toluene of a flow equalization tank, thicker, and sludge container were produced from 70.38 ppb to 103.07 ppb, from 28.18 ppb to 40.35 ppb, and from 67.92 ppb to 180.26 ppb. The producing order of VOC can be listed as follows : Sludge container ＞ Flow equalization tank ＞ Thicker.

An analytical method for trimethylamine in ambient air was developed, using headspace gas chromatography with flame ionization detection. Trimethylamine was collected on the acid filter which was impregnated sulfuric aicd in the 47 ㎜ diameter of glass fiber filter. Trimethylamine collected on the acid filter was regenerated in the headspace vial and introduced into the GC analytical column directly. Several parameters such as sample volume, equilibrium temperature and time, and slurry method of filter were optimized to provide maximum detection response. Resolution power also compared according to liquid phase of analytical column. The detection limit of method was 0.13 ppb with 50 L sampling volume. The developed acid filter method is easy to deal with the field sampling and the method was adopted as the standard method for odor analysis in Korea.

The present study aims to develop a web-based model for English teacher evaluation, which purports to encourage a teacher to get actively involved in his or her own professional development through critical reflection upon teaching. The evaluation model using portfolio is based on the assumption that the teacher should play a key role in the evaluation process in order to bring about change in teaching. Another theoretical premise of the model is that data on teaching should be gathered from multiple sources such as observation, student performance and self-appraisal. The web-based model encourages stakeholders, e.g., administrators, headteachers, parents, to take part in the evaluation process. The model reflects the findings of a questionnaire survey on teachers’ perceptions on teacher evaluation and their needs. It is suggested that a number of factors related to administration, technology and content should be considered for the effective application of the model. Some suggestions are also made concerning evaluator training, time constraints, institutional support, and further research.

The first significant modern theatre movement in Korea arose in the early 1920s. Modern Irish drama and its theatre movement has always been a major field of interest for the Korean intellectuals and dramatists who believed that it provided a model for the modern Korean theatre. The importation of Irish drama was systematically conducted by different groups from the Korean intellectuals in the 1920s and 1930s, during which period many of them published articles concerning Irish drama and the Irish theatre movement. A famous Korean writer Hyo-Seok Lee(1907-1942) published an article titled 'A Research about John Millington Synge's Drama' in 1930, a compressed version of his BA degree essay in Monthly Dae-joong-gong-ron(Public Opinion). However, despite of his fame and popularity as a writer and material for academic research, this article has been forgotten and has remained unknown. Majority of Korean scholars concentrate on Lee's novel and essays while comparatively neglecting Lee's interest towards Irish drama. The main areas of discussions are the followings. First, socio-cultural significance of Irish impact on Korean theatre will be discussed. Second, in the context of Irish influence on Korean drama, the main feature of Lee's viewpoint towards Synge will be examined in comparison with other politically oriented Korean essays.

The mushroom production reached to 1000 billion won in monetary value in Korea. We, however, do not have systematic terminology dictionary published yet. Recently new varieties of medicinal mushrooms in addition to culinary mushrooms are being introduced steadily through out the world. This makes the necessity of coordinated and consistent arrangement of terms involved in culture, cultivation and physiological aspects of mushrooms. Various components in relation to the medicinal and physiological functionality also poses ambiguity in terminology along with the terms used in breeding and genetic researches. Moreover, some of the scientific terms are being used erroneously. In order to help mushroom cultivators, students, and mushroom business personnel in understanding the terms on mushroom science and technology we intended to collect and organize all the terms related to mushroom morphology and cultivation, poison and medicinal functionality, processing and utilization, and so on. Thirteen professionals from each field participated in this project. The fields included here are : 1) Genetics and breeding of mushrooms, 2) Cultivation and physiology of mushrooms, 3) Taxonomy and ecology of mushrooms, 4) Processing and functional components, 5) Blight and insects of mushrooms

To study on antioxidant effects in the liver of 40-week-old mouse, the sample were orally pretreated 5mg/kg/day for 5 days with red ginseng saponin components(total saponin, protopanaxadiol saponin, protopanaxatriol saponin, ginsenoside-Rd, ginsenoside-Re, compound-K) for 5 days. The ability of saponin to protect the mouse liver from oxidative damage was examined by determining the activity of superoxide dismutase(SOD), glutathione peroxidase(GPx) and the contents of glutathione, the level of malondialdehyde, The only protopanaxadiol among the ginseng saponin fractions was significantly increased the hepatic SOD activity(p<0.01). The red ginseng saponin induced a slight increase of GPx activity, especially ginsenoside Rd, compound K and protopanaxatriol treatments significantly increased its activity. The content of glutathione was significantly increased by total saponin, protopanaxadiol and ginsenoside Rd(p<0.01), but the oxidized glutathione level was lowered in all the red ginseng saponin. Finally, the level of malondialdehyde was significantly decreased by ginsenoside Rd and protopanaxadiol. In conclusion, protopanaxadiol and ginsenoside Rd among the saponin fraction were especially increased in the activity of hepatic antioxidative enzyme and decreased the lipid peroxidation that was expressed in term of MDA formation. This comprehensive antioxidant effects of red ginseng saponin seems to be by a certain action of saponin other than a direct antioxidant action.

목적 : 본 연구는 임상적 활용을 위하여 LOTCA-G 번역판을 사용하여 도시지역 노인의 인지기능을 알아보고, LOTCA-G 한국판 개발을 위한 기초자료를 확보하고자 시행되었다. 연구방법 : 연구대상자는 대전광역시에 거주하는 뇌손상의 경험이 없거나 치매로 진단받지 않은 65세 이상의 노인 117명이었으며 직접 면접조사 및 LOTCA-G를 사용한 인지기능평가를 통해 자료를 수집하였다. 자료 수집 기간은 2005년 3월 11일에서 4월 2일까지로 23일간 실시되었다. 결과 : 1. 연구대상자들의 LOTCA-G를 이용한 인지기능 검사 점수는 총점 104점에 평균 92.17±10.66점이었으며, 연령이 낮은 군일수록, 교육수준이 높은 군일수록 인지기능점수가 통계적으로 유의하게 높았다.2. LOTCA-G의 각 하위영역별 평가 점수는 교육수준이 높은 군인 경우에 대부분의 영역에서 유의하게 높았고, 연령이 높은 군일수록 각 영역 별로 점수가 통계적으로 유의하게 낮아졌다.3. LOTCA-G의 각 하위영역 간 관계는 실행력과 주의력/집중력을 제외하고는 모든 영역 간에 유의한 상관관계를 보였다.4. MMSE-K와 LOTCA-G의 총점수를 비교했을 때 유의한 높은 상관관계를 가짐을 알 수 있었으며, MMSE-K의 분류별 점수에 따른 LOTCA-G의 점수는 24점 이상(96.35±5.52), 23-18점(87.72±5.52), 17점(55.40±16.56)으로 각 각 유의한 차이가 있었다. 결론 : LOTCA-G를 사용한 도시지역 노인의 인지기능수준은 연령, 교육기간에 따라 차이가 있었다. 간이신경검사인 MMSE-K와 비교하였을 때 LOTCA-G는 유의미한 상관관계를 가지고 있어 연구에서 사용된 한국어로 번안된 본 도구도 인지기능을 평가하는 데 타당함을 알 수 있었다. 그러나 외국에서 개발된 LOTCA-G를 그대로 번안 하여 사용한 것이므로 문화적, 사회적 차이로 인한 문항 간 차이점이 존재하는 것으로 사료된다. 후속 연구에서는 이러한 점을 수정 및 보완하여 한국판 LOTCA-G를 개발하는 것이 필요하겠다.

The aim of this study was to investigate the effect of ethanol extract of Fagopyrum escuentum(FE) on the melanogenesis. To determine whether ethanol extract of FE suppress melanin synthesis in cellular level, B16F10 melanoma cells were cultured in the presence of different concentrations of FE ethanol extract. In the present study, the author examined the effects of FE ethanol extract on cell proliferation, melanin contents, tyrosinase activity. Cell proliferation was slightly increased by treatment with ethanol extract of FE (25-200 μg/ml). The ethanol extract of FE effectively suppressed melanin contents at a dose of 100 μg/ml. It was observed that the color of cell pellets was totally whitened compared with the control. The ethanol extract of FE inhibited tyrosinase activity, regulate melanin biosynthesis as the key enzyme in melanogenesis. These results suggest that the ethanol extract of FE exerts its depigmenting effects through the suppression of tyrosinase activity. And it may be a potent depigmetation agent in hyperpigmentation condition.
