본 연구는 광주에서 약 25km 떨어져 있는 담양호와 광주시에 인접해 있는 광주호의 삼림유역에서 수목이 중금속을 흡수하는 양을 파악하기 위하여 소나무와 굴참나무의 엽과 뿌리, 삼림토양의 단면 중에서 L층, F층, A층에 함유된 중금속 함량과 강우, 호소수, 하천수의 중금속 함량을 ICP-AES에 의하여 분석하였다. 본 연구에서는 중금속중에서 대기와 토양오염과 밀접한 관련이 있고 동·식물의 생장 및 생육에 영향을 미치는 Mo, Zn, Pb, Ni, Cd, Mn, Cr, Cu로 제한하여 측정 분석하여 얻은 결론은 다음과 같다. 1. 생장초기의 중금속 함량은 각각 중금속이 미량으로 나타나며 원소에 따라 약간의 차이는 있으나 Mn과 Pb는 삼림토양 단면(L, F, A층)에서 높게 나타났다. 2. 생장말기의 중금속 함량은 각각 중금속이 미량으로 나타나는데 Mn과 Pb는 삼림토양 보다는 수목에서 높게 나타났는데 이는 토양에 함유된 Mn, Pb를 흡수하여 수목의 뿌리나 잎에 축적되었기 때문이다. 따라서 낙엽인 L 층에도 Mn과 Pb가 다량 함유되어 있다. 3. 뿌리를 통해서 흡수된 중금속은 잎에 집적되었다가 낙엽으로 다시 토양에 공급되는데 토양에 공급된 중금속과 토양생성과정에서 모암에서 생성된 중금속이 강우에 의하여 호수에 유입된다. 따라서 본 연구에서는 5월과 9월에 담양호와 광주호의 호소수에 중금속의 함량이 적은 것은 호소수가 하천수로 유출되어서 희석된 결과라고 사료된다. 4. 강우 역시 5월과 9월에 담양호와 광주호 삼림유역에서 중금속의 함량에 큰 차이가 없는 것은 광주시에 인접되어 있는 광주호가 도시매연이나 자동차 배기가스 등 오염물질의 영향을 받지 않은 결과라고 사료된다. 5. 생장초기는 삼림토양에 다량 축적된 중금속류가 생장말기에 이르러서는 수목의 잎과 뿌리로 다량 흡수함을 알 수 있는데 강우에 중금속류가 소량 측정되어 대기오염물질이 엽을 통한 직접 흡수보다는 뿌리를 통해 엽으로 이동된 것으로 생각된다. 6. 광주호 삼림유역은 광주시에 인접해 있으므로 도시매연이나 자동차 배기가스 등의 영향을 많이 받아 강우나 호소수, 수목의 뿌리, 잎, 토양단면에 중금속이 담양호 삼림유역보다 더 많이 측정되리라고 생각하였으나, Mn과 Pb에서 생장초기에는 담양호 삼림유역의 소나무의 잎과 뿌리에서 더 많이 측정되었고, 생장말기에는 광주호 삼림유역의 굴참나무의 잎과 뿌리에서 높게 나타났다. This study was to compare the concentrations of heavy metals absorbed in Pinus densiflora with those absorbed in Quercus variabilis, by analysing with ICP-AES the concentrations of heavy metals in leaves and fine roots of both trees, the concentrations in L layer, in F layer, and in A horizon of soil profile, and the concentrations in rainfall, in lake water and in streams in the above both forest ecosystem of the Tamyang lake and Kwangju lake watershed. The selected heavy metals were Mo, Zn, Pb, Ni, Cd, Mn, Cr, Cu, closely related with the air pollution and soil contamination, and essential for the growth of both plants and animals. the samples were collected at the early period of growth on may, 1997 and at the closing period of growth on september, 1997. 1. In early period of growth, the concentrations of Mn, Pb were very much higher than those of others in L, F layer and A horizons of soils profile. But in the closing period of growth, the amounts of Mn, Pb were included more in the trees than in the soils. This was considered as the results of accumulating in the tree tissues after absorbing the heavy metals from soils. But very little contents of other heavy metals were included in the profile and in the trees in the early period or in the closing period of growth. 2. The movement of heavy metals cycled from the soils to the plants through the absorption of the metals with other nutrients and adversely from the fallen leaves of plants to the soils. The heavy metals derived from the plant residues and the parent rocks put in the lake and stream by rainfall. The concentration of heavy metals generally were in low both lake water of Tamyang lake and Kwangju lake, because both lake water were diluted by rain water or stream water. 3. There was no great difference in the concentrations of heavy metals included in rainfall of both Tamyang lake and Kwangju lake watershed and there was no any evidence affected to the both areas by the atmospheric pollution of Kwangju city.

An analysis of the regional community structure of the summer birds on Mt.Moodung was observed over a period of the summer, from June to September, 1989. Observation the birds of passing migrant, summer visitor, and resident was carried out at various levels in three different areas around Mt.Moodung. The areas and results are as follow. 1. As the altitude hightened in the area of northeast side of this mountain, Sanjiang-Komacjae-Gyubongam………9km(499 individuals of 28 spe-cies), deciduous forest community(dominance tree-Quercus grosseserrate) 2. In the area of southwest, Gyubongam-Jaugbuljae-Tokibong-Baramjae-Sanjang………6km(432 individuals of 28 species), deciduous forest commu-nity(Sasamor pha pur purcens var. bolialis var. bolialis-over 800m, Stewartia Koreana-below 700m) 3. Covered with southwest and westnorth, Tokibong-Chungbong-Jeungshim Temple-Jisan resort………9km(522 individuals of 28 species), deciduo-us forest and glass field because of fire(Arundinella hirta, Hiscanthus sinensis) The percentages of species diversity(for the total of all species), evenness, and dominance were calculated to show indices for related abundunce of species at the certain side of forest community.

The Working Group on the revision of Clinical Research Methodology for Acupuncture met in Seoul, Republic of Korea from 24 to 26 August 2005. The main objectives of the meeting were to review the regional publication guidelines for Clinical Research on Acupuncture, to make necessary revisions in the guidelines, to make recommendations on further collaboration and activities in the field of research on acupuncture, and to discuss scientific evidence-based approaches in the clinical research on acupuncture. Fourteen members from the eight Member States, one secretariat staff from the WHO Regional Office for the Western Pacific and ten observers from the Republic of Korea attended the meeting. The members presented their papers to review the current status of clinical research on acupuncture. The drafts of proposed revision to the previous guidelines for clinical research methodology on acupuncture were discussed extensively. The issues covered during the discussion included: the definition of the new terms; reorganization of clinical research design; revision and update of contents (e.g., control group); introduction of Institutional Review Board (IRB) on the section of ethical approval; additional outcomes including health-related quality of life (HRQOL), qualitative measures, etc. In the course of these discussions, the working group developed the revised guidelines for clinical research on acupuncture and made recommendations for promoting the dissemination of the revised guidelines.

Edible flower means a flower that is good to eat is subject to either cooking or appetizing. In general, people eat edible flower as raw so that the loss of vitamin and inorganic are minimal. Edible flower is usually utilized as salad material or aromatic, decoration for jelly or cake and solid stuff in soup. Thus, decorating food by edible flower improves flavor, fragrance and appetite. Edible flower serves various purposes both east and west. In Korea, Edible flower is mainly subject to soup, cooked potherbs, frying, tea stuff, brewing and etc, whereas in Japan, its various usage covers cooked potherbs, pickle, sliced raw fish, frying, salad, jelly and decoration. On the other hand, Edible flower is used as numerous salad and tea stuff, condiment, roasting, meat, sweets and desserts in Western Hemisphere.

In prder to clarify the changes of serum chemical values(AST, CPK and LDH activities)and LDH isoenzyme fractions in frequent occuring some diseases of dairy cows, total 48 cows(40 patients: 18 with downer cow syndrome, 17 with abomasal displacement and 5 with acute mastitis and 8 controls: clinically healthy cows) were examined. The results obtained were as follows: 1. In changes of total serum enzyme activities of patients group, increase of serum AST(P<0.001), CPK(P<0.01) and LDH activities(P<0.01)were observed in groups of downer cow syndrome and abomasal displacement, respectively by comparison with control group. Increase of AST only was found in group of acute mastitis(P<0.05). 2. In LDH isoenzyme fractions, increase of LDH₁(P<0.01), LDH₂(P<0.05), LDH₃(P<0.01), LDH₄(P<0.01) and LDH_5(P<0.01)fractiona was observed in group of downer cow syndrome and also marker increase of LDH4 and LDH5 fractions was noted in this group. The increase of LDH₁, LDH₂ amd LDH₃ (P<0.01)fractions was found in group of abomasal displacement, but group of acute mastitis showed similar result to that of control group.

Two new benzophenones, acredinones A(1) and B(2), were isolated from a marine-sponge-associated Acre-monium sp. Fungus. Their chemical structures were elucidated on the interpretation of spectroscopic data. The structure of 1 was confirmed by palladium-catalyzed hydrogenation, followed by spectroscopic data analysis. Acredinones A (1) and B (2) inhibited the outward K currents of the insulin secreting cell line INS-1 with IC50 values of 0.59 and 1.0 um, respectively.
