本 硏究에서 使用된 3個樹種의 供試木인 잣나무, 전나무, 주목의 3∼4年生 苗木에 대한 5개 수준(0, 0.5, 1, 2, 4ppm)의 亞黃酸가스 處理 實驗을 통하여 供試木의 可視的被害 發見 및 葉中 水溶性 硫黃含量 그리고, 體內 葉綠素의 含量, 樹皮酸度, 葉中水分含量을 測定하였던 바 다음과 같은 結果를 알 수 있었다. 1. 亞黃酸가스 處理에 대한 被害症狀의 程度를 가장 敏感하게 나타낸 數種은 供試木中 전나무, 그리고 주목의 順으로 나타났다. 被害樣相은 處理 濃度 2ppm 以下의 低濃度에서는 被害症勢가 發見되지 않았으나, 4ppm의 高濃度 處理에서는 그에 대해 나타나는 被害症勢가 24時間 經過後 잎의 선단부 부터 發見되기 始作하였다. 2. 供試樹種間의 濃度別 葉中 水溶性 硫黃 含量은 亞黃酸가스 濃度가 높아질수록 점차 增加하였고, 樹種別 平均 葉中 水溶性 硫黃 含量은 전나무가 0.076±0.026%로 이들 3개 樹種의 供試木을 통하여 가장 많이 나타났으며, 그 외에 주목은 0.0711±0.018%, 그리고 잣나무는 0.0704±0.019%의 順을 보였다. 3. 供試樹種間의 亞黃酸가스 處理의 濃度別 葉綠素 含量은 Gas의 濃度가 높아질수록 점차 減少하였는데, 樹種別 Total 葉綠素 含量은 주목이 4.704±1.33 ㎎/g으로 가장 많았으며, 전나무는 3.597㎎0.82 ㎎/g, 잣나무는 3.028±0.72 ㎎/g등을 나타내었다. 4. 供試樹種間의 濃度別 樹皮酸度는 亞黃酸가스濃度가 높아질수록 점차 減少하였는데 全體 平均酸度는 전나무가 pH 4.774±0.33으로 가장 높았으며, 주목은 pH 4.556±0.25, 잣나무는 pH 4.486±0.31의 結果를 나타내었다. 5. 供試樹種間의 濃度別 葉中水分含量은 亞黃酸가스의 濃度가 높아질수록 점차 減少하였는데 全體 平均 葉中水分含量은 주목이 62.74±2.1%로 가장 많았으며, 잣나무가 60.20±2.2%, 전나무가 57.70±2.5%의 結果를 나타내었다. This study was carried out to obtain information for the effect of sulfur dioxide on some seedlings as Taxus cuspidata, Pinus koraiensis, and Abies bolopbylla. Selected seedlings put in chamber(85×85㎝) were treated by sulfur dioxide at five levels(0, 0.5, 1, 2, 4ppm) for four hours. The results obtained from this research as follows: 1. Visible damages of sulfur dioxide were showed from margin of leaves, at high concentration(4 ppm) about 24 hours later and that orders were Pinus koraiensis, Abies bolophylla, and Taxus cuspidata. 2. It was appeared that the water soluble sulfur contents of among tree species increased with increasing concentration of sulfur dioxide and soluble sulfur contents of Abies bolophylla(0.0796±0.026%) were higher than those of Taxus cuspidata(0.0711±0.018%) and Pinus koraiensts(0.0704±0.019%). 3. Leaf chlorophyll contents of among tree species decreased with increasing concentration of sulfur dioxide. It showed that leaf chlorophyll contents were the heighest in Taxus cuspidata(4.704±1.33㎎/g) follow by Abies bolophylla(3.597±0.82㎎/g) and Pinus koraiensts(3.028±0.72㎎/g). 4. Bark acidity of among tree species decreased with increasing concentration of sulfur dioxide and bark acidity of Abies bolophylla(pH 4.774±0.33) were higher than those of Taxus cuspidata(pH 4.55±0.25) and Pinus koraiensif(pH 4.486±0.31). 5. Leaf water contents of among tree species decreased with increasing concentration of sulfur dioxide. It showed that leaf water contents was the highest in Taxus cuspidata(62.74±2.1%) follow by Pinus koraiensis(60.20±2.2%) and Abies bolophylla(57.70±2.5%).

잣나무 조림지를 대상으로 가지치기의 정도가 임목의 생육에 미치는 영향과 가지절단방법이 절단면의 유합속도에 미치는 영향을 알기 위하여 가지치기 정도와 가지절단방법을 달리하여 시험조사된 본 연구에서는 다음과 같은 결과를 얻었다. 1. 가지치기한 후 2년까지는 수고생장이 가지치기 정도의 영향을 받는 것으로 나타났지만 그 이후부터는 그다지 영향을 받지 않았다. 2. 흉고직경생장에 있어서도 가지치기 정도의 영향을 크게 받지 않는 것으로 나타났다. 3. 가지의 절단면 형태에 따른 유합정도는 지융부 포함 절단법(91.9%)이 지융부 제외 절단법(78.0%)보다 더 높은 유합정도를 나타내었다. 4. 가지의 절단직경의 크기와 유합정도와의 상관관계는 처음 2년간은 두가지 방법에서 모두 유의성을 인정할 수 있었는데 특히 지융부 포함 절단법은 절단후 2년동안은 절단직경이 클수록 빠른 유합정도를 보였으나 어느정도의 유합이 이루어진 후에는 절단직경의 크기와 유합정도 사이에는 유의성을 찾을 수 없었다. This study was conducted to find out the effect of pruning on tree growth and the effect of pruning methods on healing of wound orientated Pinus koratensis afforested land. Through-out a different test in pruning and cutting-methods of pruning obtained result as follows. 1. Degrees of pruning have an effect on height growth for two years after pruning but since that time they not an effect on height growth. 2. Degrees of pruning have not an effect on D.B.H. growth. 3. Healing rate by pruning method were B method(straight angle cut line 91.9%)higher than A method(end of turgid cut line(78.0%). 4. Correlation coefficients between healing of wound and diameter of cutting face were allowed significant in A method(P>0.05). The larger the diameter of cutting face was the faster the healing of wound in all methods for two years. But B method was allowed no significant after two years.

The cultural interchanges have been dramatically increased between Korea and China since the diplomatic agreement on the 24th of August, 1992, Among the several discussions between the two countries, particularly building up Korea traditional garden will take concrete shape in Kwan-dong in China. These followings are the basic plans. First, the project approaches the garden as a place for the interchange and the cooperation between the counties, and where people can experience Korea traditional garden. Secondly, it is plotted to express the distinct character and originality of Korea traditional garden. Third, it applies the same materials, subject matters and the same construction method of Korea traditional garden. We can use the most similar materials if it is not possible. Fourth, the project is plotted to make the efficient use of the land form to decrease the damage of natural environment.

This study does questionnaire over recognition of landscape, major landscape and impressive site in rural community, and research visual preference through precessing pictures with a computer about major landscape. The landscape with natural fabric generally harmonizing with background is high in preference. Also, though major landscape factors are similar, preference is different according to shape, size, quality and color.

지하구조물의 건설을 위한 깊은 굴착으로 인해 근접구조물에 많은 피해가 발생하고 있다. 피해를 일으키는 주된 원인은 흙막이 벽체의 수평변위에 의한 지반침하와 지하수위 저하나 진동등에 의한 압밀, 다짐 발생에 따른 지반침하 등이다. 지금까지 대부분의 연구는 현장계측을 이용하였으므로, 벽체의 변위와 지반침하에 영향을 미치는 많은 인자들 각각의 영향을 밝히기는 대단히 어려웠다. 본 연구에서는 실내 모형실험을 통하여 최종 굴착시의 주동파괴면 안쪽에 놓여있는 구조물의 침하를 최소화할 수 있는 지반앵커(1단, 2단)의 위치 및 간격을 결정하였다. 실험결과, 앵커 1단 설치, 앵커 2단 설치의 경우가 모두 앵커 깊이 비=0.4∼0.5일 때, 근접구조물의 침하가 최소가 되었다. 또, 지반 굴착시의 지반변형을 관찰하여 위의 사실을 확인하고, 지반 파괴면의 위치 및 형상을 구하였다. The structure is often deformed and damaged by deep excavation. This deformation and damage are mainly made by ground settlement(consolidation, compaction) owing to groundwater drop or vibration etc. and lateral movement of retaining wall. Then, most studies about deformation of ground have done by using results of site measurement, so it was very difficult to find each effect of many factors separately. The purpose of this study is to decide the location and interval of ground anchor( lst, 2nd ground anchor) to be able to minimize the settlement of adjacent structure located inside the active failure surface by model test at laboratory. As results of this model test, it was known that the depth ration of anchor to minimize the settlement of near-by structure was 0.4∼0.5, and by the observation of ground deformation during excavation, the direction and magnitude of displacement and the failure line could be known.

Background and Objectives: Two hundred cases of the open heart surgery due to congenital and acquired heart disease were done using the cardiopulmonary bypass in the Department of Thoracic and Cardiovascular surgery, Chosun University Hospital from November, 1980 to June, 2001. Material and Methods: The number of congenital heart disease was 132 cases. 68 cases were acquired heart disease. 'The age of the congenital heart disease was from 22 days to 45 years. In the acquired heart disease, the age was from 14 to 72 years. Result: Congenital heart disease consisted of 113 congenital acyanotic heart disease, 19 congenital cyanotic heart disease. Corrective operation was done for congenital heart disease with 4. 5 % operative mortality. Of 68 cases acquired heart disease, 44 patients were valvular heart disease, 3 cardiac tumors, 9 ischemic heart diseases, 12 aortic dissections and etc. The operative mortality was 13%. Conclusion: The postoperative complications were appeared in 68 cases and the complications were wound infection, occipital alopecia, low cardiac output syndrome, arrhythmia, septicemia etc. The mortality after open heart surgery was 15 cases and the causes of death were low cardiac output syndrome, septicemia, respiratory failure and left ventricle rupture.
