서울 도봉산의 식생구조를 북동사면과 남서 사면과의 차이에 따라 수목을 대상으로 분석 하였고, 아울러 식생구조와 토양의 제반 성질 (pH, 토양 함수량, 유기물, 총 질소, 치환성 양이온, 무기인산을 결부하여 설명하고자 시도하였다. 또한 조사지역과 수종과의 관계를 관찰하기 위하여 이를 Bray-Curtis(1957)의 방법인 Polar ordination으로 좌표상에 표시하였다. 조사 결과, 일조에 의한 수분증발의 차이에 따라 북동사면의 토양이 남서사면보다 다소 습하고 토양의 양분 함량이 많은 것으로 나차났다. 이런 토양 성질의 차이에 따라 남서사면에서는 졸참나무(Quercus serrata), 소나무(Pinus densiflora), 신갈나무(Q. mongolica), 돌배나무(Pyrus pyriforia), 진달래(Rhodo-dendron mucronulatum), 풀싸리(Lespedeza intermedia), 붉은병꽃나무(Weigela florida)등 다소 건조한 조건에도 견딜 수 있는 종들이 우세하였고, 북동사면에서 단풍나무(Acer Psrudo-sieboldianum), 오리나무(Alnus ja-ponica), 아카시아(Robinia psedoacacia). 국수나무(Stephanandra incisa), 산철쭉(Rho-dodendron yedoense var. Poukhanense) 등이 남서사면에 비해 우세하였다. 교목의 경우 남서사면의 출현종은 1800m^2 당 1,405개체, 북동사면은 1,196개체로서 남서 사면의 개체수가 다소 우세하였으나, 기저면적에 있어서는 남서사면은 14,818.9cm^2, 북동 사면은 40,987cm^2로서 남서사면의 식생구조가 북동사면보다 다소 왜소한 교목으로 이루어져 있다는 것을 알 수 있었다. 관목의 경우는 남서사면의 출현종의 개체수는 1,976개체, 북동사면의 출현종의 개체수는 2,089개체로서 양 사면이 비슷한 개체수로 이루어져 있었다. Bray-Curtis의 방법에 따라서 조사지들의 위치를 표시한 결과, 거의 모든 조사지에서 떡갈나무가 우세종이었고 단풍나무, 소나무가 우세한 지역은 토양 함수량, 유기물 함량이적고, 질소의 함량이 많아/ㅅ으며, 떡갈나무가 우세한 지역은 토양 함수량, 유기물 함량이 가장 많고, 치환성 칼륨의 함량이 적었다. 또 한 각 종들의 위치를 표시한 결과 돌배나무와 신갈나무가 가장 유사도가 적었으며, 북동사면에 다소 우세하게 출현하는 떡갈나무, 오리나무, 아카시아와 남서사면에서 우세하게 출현하는 졸참나무, 소나무, 신갈나무, 돌배나무를 분류하여 나타낼 수 있엇다. This study was carried out to examine the differences in tree species and chemial soil propeties between the south-west and north-east slopes of Mt. Do Bong using the method of Bray and Curtis(1957). Moisture and nutrient atatus of soil was detected to be higher on the north-east slope than on the south-west slope, on the basis of the evaporation rate by the solar radiation. On the south-west slope, most of the trees, which observed to be dwarf, are considered as a species resistant to the dry condition, while the vegeration of north-east slope is dominated by the trees larger than those of south-west slote. Oak was the most commonly found in the plots. Plots diminated maples and pines have low contents of soil water and organic matter, and high total nitrogen, whereas by plots dominated by oaks show large quantites of soil water and organic matter, and low exchangeable potassium. From the results of positioning the species, the plants were subdivided into characteristic south-west and north-east groups.

It was generally known that the aging treatment of paper is accompanied with the reductions in physical and optical properties of individual fibers and sheet. In particular, the paper prepared with mechanical pulps occurs the yellowing of sheet, during aging, due to the absorption of light or temperature, and finally has limitation in widely applicable functions of paper. The aging behaviors of paper can be discussed with three groups of factor. One is considered to external factors, like heat, light and moisture. Another is commented with environmental factors, like oxygen, nitrogen, sulfur, and other air pollutant materials. The other is explained by internal factors, like pulp types, lignin contents, and so on. In this paper, the aging behaviors of paper prepared with BCTMP were studied in order to know how to affect in physical and optical properties of paper. For modification of fibers properties, a commercial enzyme was pretreated in the slurry of BCTMP, before handsheet-making. Sheets were aged by accelerated heat treatment. The comparisons were carried out in mechanical strength properties and color reversions. Aging treatments were resulted in higher brightness reductions, in enzyme pretreated paper.

朴奉奎,金鍾熙 梨花女子大學校 韓國生活科學硏究院 1985 韓國生活科學硏究院 論叢 Vol.35 No.-

The germination of seeds of Amaranthus retroflexus and Chenopodium album were carried out in two series of experiments. In the first series, the effects of different temperature (35℃, 23±2℃, 15/6℃) were studied and in the second, the effects of the same temperature combined with three different concentrations of potassium nitrate (0M, 0.002M, 0.02M). The seeds of Amaranthus were incubated in continuous darkness, while the seeds of Chenopodium were in light. Germination was recognized when radicle appeared. During each examination all garminated seeds were counted and removed from the petri-dishes. The highest germination rate for Amaranthus (95%) occurred at temperature of 35℃ and for Chenopodium (88%) occurred at 23±2℃. Which might be set as optimum temperature regime for germination. Chenopodium had generally wider temperature regime for germination than Amaranthus. In Chenopodium germination rate increased as nitrate concentration increased at 35℃ and 23±2℃. The greatest effects of nitrate were especially noticeable in the germintion of Chenopodium seeds at 23±2℃ temperature regime. It appeared that germination with 0.02M nitrate solutions increased 2.0 times more than in the control. These results demonstrate that the action of potassium nitrate was beneficial for the germination of light-favored seeds.

충청북도 괴산군 3개 지소 야초지의 토양 요인(지형, 토성, 토양 함수량, 토양 염류, 토양 유기질) 및 식물체 무기 성분의 함량과 밀접한 관계가 있음을 확인할 수 있었다. This report is an attempt to study the relationship between soil and vegetation in native grasslands. The research was carried on from May 1976 to July 1976. The results from it are: (1) The grassland vegetation was dominated by Trifolium repens Linne in Cheong-cheon-Ri, Festuca ovina Linne in Yeontan-Ri, and Arundinella hirta Tanaka in Tabseon-Ri. (2) The standing crop was 98.15 g/m^2 in Yeontan-Ri, and 67.80 g/m^2 to 163.74 g/m^2 in Tabseon-Ri. (3) The daily productivity in Cheong-cheon-Ri showed 3.10 g/m^2, which was the highest of the three sites. (4) The daily productivity in Yeontan-Ri was 2.66 g/m^2. (5) The daily productivity in Tabseon-Ri showed 2.28 g/m^2, which was the lowest of the three sites. (6) The above results prove that soil fertility was closely related to topographical features(especially slope), the surrounding vegetation and mother rock. It is also known that, by dint of these factors, available phosphorus, total nitrogen, water content, ignition loss and cation exchange capacity of the soil influenced greatly the productivity upon. (7) Plants in fertile soil were apt to have more inorganic components than those in sterile soil. (8) The characteristics of the content of ignorganic components were as follows: The contents of SiO_2 in Poaceae and nitrogen in Fabaceae were much higher than those of other components. (9) Poaceae and Fabaceae in these sites, though they were native grasses, were considered that they had sufficient nutrient value for fodder, because they had more inorganic components than cultured in the pasture.

Graves' disease is characterized by diffuse hyperplasia of thyroid gland, hypersecretion of thyroid hormones, ophthalmopathy, and localized pretibial myxema. Although the pathogenesis of Graves' disease is still obscure, but the TSH receptor antibodies have pathophysiological role in the hyperplasia of the gland and autonomous over production of thyroid hormones through the stimulation of TSH receptor. Radioiodine (^1311I) has been used for the treatment of Graves' disease for many years and is regarded as an treatment for the cases who is not remit following a course of antithyroid drug. To evaluate the efficacy and side effects of radioiodine treatment in Graves' disease, we studied clincal outcome after fixed dose(5-20mCi) of ^131I The results were as followings; 1) The mean dose of 9. 1mCi of ^131I administration makes 12 patients euthyroid out of 41 patients with Graves' disease. The dose of radioiodine(^131I) used for the treatment was not significantly different in hypothyroid group (3/41; 7.3%) or hyperthyroid group(26/41; 63.4%) after ^131I treatment. 2) The clinical outcomes after radioiodine (131I) treatment was not depend on the age and sex and thyrotropin receptor binding inhibitory immunoglobulins(TBII) of radioiodine(^131I) administered patients, but only the short duration of antithyroid drug treatment(the period of observation of the responce to antithyroid drug) before the radioiodine administration increase the incidence of radioiodine induced hypothyroidism. 3) The cumulative incidence of hypothyoidism after radioiodine(^131I) administration was 39.4% after third treatment. In conlusion, radioiodine treatment in fixed-dose is effective; it can induce euthyroidism or hypothyroidism in 33 out of 41 patients without major complications. With this study, we could confirm the efficacy of radioiodine treatment in a minor groups of patient who its difficult to maintain remission after antithyroid drug.
