間伐이 일본잎갈나무의 直徑成長에 미치는 影響 : Larix leptolepis Gordon

權泳徹 진주산업대학교 1984 論文集 Vol.22 No.-

本 硏究는 일본잎갈나무人工林에서 間伐이 일본잎갈나무의 直徑成長에 어떤 影響을 미쳤는 가를 調査한 것이다. 그 結果를 要約하면 다음과 같다. 1. 間伐區(B)와 無間伐(A)는 幼齡林分에서는 거의 비슷한 成長을 하였으나 11年以後부터 平均年輪幅과 年輪의 平均斷面積이 無間伐區보다 間伐區가 急進的으로 增加된 것으로 보아 11年에 間伐이 實施된 것으로 사료된다. 2. 間伐區는 無間伐區보다 平均年輪幅은 約 1.4倍로, 年輪의 平均斷面績은 約 1.5倍로, 年輪의 累加斷面積은 約 1.8倍로 成長하였으므로 間伐이 일본잎갈나무 直徑成長에 크게 影響한 것으로 생각된다. This study was carried out to determine the effect of thinning on the diameter growth of the artificial forest of Japanese larch (Larix leptolepis Gordon) The results obtained were as follows: 1. The thinning plot (B) and non thinning plot (A) were shown growth rate of both similarly is brush stage, but since after 11 years the thinned plot was shown more increment than unthinned plot about the average annual ring width and average cross­sectional area of annual ring. Therefore I conclude that may be better thinned at 11 years. 2. The thinning plot was shown growth rate of 1.4 times of average annual ring width, 1.5 times of average cross section of annual ring and 1.8 times of accumulated cross section area related to tree age than the non thinning plot. It was assumed that this tendency would be caused by the thinning.

거친 표면을 가진 흡수체와 버퍼의 측면에 의한 극자외선 산란효과

권영근,심상진,김종회,김옥경,오혜근 한양대학교 이학기술연구소 2003 이학기술연구지 Vol.6 No.-

마스크 상의 거친 표면을 정의하기 위해서 Monte-Carlo 방법이 적용되었다. 극자외선 마스크의 거친 표면 함수, 즉 power spectral density 에 의해 표현된 무작위적인 표면의 높이 변화는 상면에서의 전기장을 계산하기 위해서 재정의 되었다. Feynmann의 접근 방식과 유사한 산란에 대한 일반식을 유도하였고, 이는 결상과정에서 마스크의 단차상의 거친 측면에 의한 효과를 알아보기 위해서 적용되어졌다. 거친 표면과 완전히 편평한 표면에 대한 전기장의 위상과 진폭 변화 정도를 비교하기 위해서 다중 산람 문제 또한 여러 다른 패턴에 대하여 이 논문에서 다뤄졌다. The Monte-Carlo Method is adopted to define the roughness of the mask structure. A random surface height variation described by power spectral density for the rough surfaces of an estreme ultraviolet (EUV) mask is to be redefined to calculate the field in the image plane. A general explicit formula of the scattering, which is analogous to Feynman's approach, is derived, and it is adapted to the EUV mask structure to evaluate the effect of the surface roughness of the side wall of the mask topography on the image formation. The multiple random scattering problems are dealt with the different pattern types in order to compare field variations in phase and amplitude with the ideal flat surface.

The purpose of this study is to design the requirements for the materials of stabilizing slurry and to determine the optimum slurry mix design based on the bentonite that used in the in-ground diaphragm wall of LNG receiving terminal. After the materials and mix conditions of stabilizing slurry investigated and tested, materials and the optimum mix design according to testing items including funnel viscosity, fluid loss, cake thickness and specific gravity are proposed. As test results, the optimum mix design and required performances are selected as following range. the upper limit ratio of bentonite is 2.0% and polymer is 0.1% considering the funnel viscosity and dispersion agent is 0.05% considering the fluid loss. Also all materials are composed of GTC4 as bentonite, KSTP as polymer and Bentocryl as dispersion agent. All test results are satisfied our specifications for stabilizing slurry.

분체계 고강도 자기충전 콘크리트의 배합요인에 관한 연구

권영호 동양대학교 2008 동양대학교 논문집 Vol.13 No.1

This study describes a selecting process of the optimum mix proportion for the high strength and self-compacting concrete placed in main structures of LNG above tank. This concrete requires high strength level about 60~80MPa, low hydration heat, balance between workability and consistency without vibrating in the actual work. For this purpose, low heat Portland cement (Type Ⅳ) and fly ash(Class F) are selected and mix design factors including water-binder ratio (W/B), replacement ratio of fly ash for unit water content (165kg/㎥) are tested. As experimental results, low heat Portland cement shows lower the confined water ratio than another cement type and the optimum replacement ratio of fly ash in order to improve properties of the binder-paste shows 10% by cement weight considering test results of the confined water ratio (βp). Also, flowability of the high strength and self-compacting concrete by using fly ash about 10~20% is improved. The replacement ratio of fly ash 10% and water-binder ratio in the range of 25~27% are suitable to the design strength about 80MPa and cost. In case of the design strength about 60MPa, the replacement ratio of fly ash and water-binder ratio show 20% and 25~30% separately. Based on the results of this study, the optimum mix proportions of the high strength and self-compacting concrete will be applied to the actual construction work of LNG above tank as a new type.

Objective : In view of the facts that education about diseases and realization of the need form drugs can improve compliance of the patients, we assessed the knowledge about drugs and medication compliance in psychiatric outpatients. In addition, we investigated factors that influence patients compliance to develop a model of medication compliance. Methods : One-hundred twelve male and eighty female psychiatric outpatient were asked about drug information using questionnaires. We developed a model that predicts medication compliance using chi square tests and multiple regression analysis. Results : More than a half of the patients knew at least one of the names and the effects of the drugs they had taken, but many of them didn't know the side effects of drugs. About eighty percent of the patients showed good compliance. Knowledge of side effects, belief in the benefits of drugs, and level of education could predict medication compliance reliably. Conclusions : Because education level could not be managed by physician, we could enhance compliance through education about drug side effects and benefits of medications.

間伐이 편백나무의 直徑成長에 미치는 影響

權泳徹,金是璟 진주산업대학교 1977 論文集 Vol.15 No.-

間伐이 편백나무의 直徑成長에 미치는 影響을 究明하기 위해서 南海郡 二東面 所在 25㏊의 편백나무 林分中 北向林分(A)에서 間伐區(A_1)와 無間伐區(A_2)를, 또한 西向林分(B)에서 間伐區(B_1)와 無間伐區(B_2)를 각각 0.1㏊씩의 標準地를 選定하고, 이 標準地의 林木을 生長錐를 使用해서 胸高部位의 南北 두 方向에서 Core를 採取하였다. 이 Core의 各 年輪폭을 測定하여 直徑成長의 實態를 考察한 바 이를 要約하면 다음과 같다. (1) 北向林分의 間伐區는 無間伐區에 比해서, 또한 西向林分의 間伐區는 無間伐區에 比해서 매우 넓은 年輪폭을 形成하였으며 한 年輪폭의 平均斷面積과 年輪폭의 累加面積은 2倍 以上의 成長을 하여 間伐의 效果를 뚜렷하게 나타내었다. (2) 西向林分의 間伐區 및 無間伐구는 北向林分의 間伐구 및 無間伐區에 比해서 다소 좋은 성장을 나타내고 있으며 이는 立木度, 方位, 傾斜度, 土深, 標高 등 立地條件의 差異로서 이루어진 것이 아닌가 생각된다. This study was carried out to determine the effect of thinning on the diameter growth of hinoki-cypress (Chamaecyparis obtusa Endl.) Each hinoki-cypress stand was seleced from the 25 ㏊. stand located at Leedong-Myeun Namhae-Goon. Each 0.1 ㏊. stand was designed by the thinning plot (A1) and the non thinning plot (A2) on the northern stand (A), and the thinning plot (B1) and non thinning plot (B2) on the western stand (B). This sample plot of the standing trees were taken the core of the breast hight (1.2m. above the ground) by using the increment borer on both the southern and northern directions. The results obtained were as follows : 1. On both western stand and northern stand, the annual ring width in thinned trees was wider than that in the unthinned. Each average cross section area and the annual ring area summed in thinned trees were more than twice larger than those in the unthinned. There was a significant effect of the thinning on diameter growth. 2. Growth rate of both thinned plot and the unthinned plot of the western stand was better than that of both thinned plot and unthinned plot on the northern stand respectively. It was assumed that this tendency would be caused by the differences of soil site conditions such as density of trees, bearing, degree of slope, soil depth, and altitude etc.

권기린,오영옥 제주대학교 공과대학 첨단기술연구소 2002 尖端技術硏究所論文集 Vol.13 No.1

A four cycle diesel engine performance test was performed with four kinds of oils such as rape seed oil, effective micro-organism rape seed oil, activated clay rape seed oil and light oil. The experiment was conducted at full load condition with constant injection time of the engine and the test oil temperature was maintained at 70±2℃. The torque and the horsepower with rape seed fuel is increased about 10% compare with light seed oil at full load condition of the engine. The emission of the smoke gas was decreased 29%, 38% and 52% compare with light oil in rape seed oil, effective micro-organism rape seed oil and activated clay rape seed oil respectively. Engine inspection results shows that the soot adherence amount of the cylinder head piston head is higher in following order: activated clay rape seed oil > effective micro-organism rape seed oil > rape seed oil > light oil.
