權泳徹 진주산업대학교 1978 論文集 Vol.16 No.-

편백 1-1苗를 生産하는데 보다 더 效果的인 方法을 摸索하고져 本校의 苗圃場에서 편백 1年生苗를 植栽密度別로 床替하여 生長狀態를 試驗한 結果를 要約하면 다음과 같다. 1. 植栽密度가 낮은 C區, D區 및 E區는 植栽密度가 높은 A區와 B區보다 生育空間이 比較的 넓어서 苗高生長이 좋았다. 2. 根元苗生長도 植栽密度가 낮은 C區, D區 및 E區가 좋았다. 3. 旱魃로 因해서 5月에 床替苗가 높은 枯死率을 나타내었으나, 그 後에는 僅少한 枯死率을 나타내었으므로 枯死率은 植栽密度와 關係가 없었다. 4. 편백 2年生苗의 養苗는 合格苗의 得苗比率이 높은 C區로 床替하는 것이 1年生苗의 損失이 적고 床替하는 勞動力도 節約된다고 생각된다. This study was carried out to investigate the effective was Producing hinoki-cypress (Chamaecyparis odtusa Sieb. et Zucc.) Seedlings(1-1) and therefore was transplanted hinoki-cypress seedling(1-0) as each planting density in our forestry Seedbed and was investigated growth of seedlings. The results obtained were as follows : 1. In C.Plot, D. Plot and E. Plot of low planting density the height growth of seedling was made a good record owing to have large width than A. plot and B. plot of high planting density. 2. The root collar diameter growth of seedling was made a good record in C. plot, D. plot and E. plot of low planting density. 3. From a drought the transplanting hinoki-cypress seedling was dead extremely much on May and since then was shown few dead ratio, because there was no connection between dead ratio and planting density. 4. I conclude that hinoki-cypress seedling(1-1) is had to transplant at C. plot of good seedling as possidle of standing the test and good ratio as possible and that is substracted labour transplanting hinoki-cypress seedling(1-0) with using few seedling.

전력용 반도체 소자를 이용한 가변전압, 가변주파수 고주파 인버터의 응용은 무정전 전원장치나 유도가열등 응용범위가 매우 넓다. 본 연구에서는 L,C공진회로로 링크된 2조의 full-bridge 인버어터회로를 병렬제어하는 기법을 제안하고 있으며 MOSFET로 구성된 각 인버어터는 한개의 등가스위치 모델로 되어 직렬공진 half-bridge형 고주파 인버어터 회로를 구성하고 있다. 게이트 제어기법으로 각 소자의 구동 주기를 분할 제어하여 출력전류 페이저를 합성하는 시분할 게이트 구동방식을 사용하고 이에 따른 인버어터의 회로동작 모드를 분석하고 해석 하였다. The proposed systems can be used power supplys for high power conversion and high frequency induction heating systems. This research proposes a high frequency resonant inverter consisting of equivalent half-bridge model in combination with two L-C linked full-bridge inverter circuits using MOSFET. As a output power control strategy, the time-sharing gate control method is applied. Also, analysis of operating MODE and state equations are described.

油菜油 燃料를 利用한 디젤耭關의 性能特性에 關한 實驗的 硏究

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.

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.

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.

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.

權泳徹,金是璟 진주산업대학교 1983 論文集 Vol.21 No.-

本硏究는 소나무를 資料로 하여 林木의 높이別 年輪幅에 나타나는 生長의 패턴을 解析하고 또한 林木의 密度가 年輪生長에 어떤 影響을 미치는가를 調査한 것이다. 그 結果를 要約하면 다음과 같다. 1. 斜面方向系列의 年輪幅生長 패턴은 樹冠의 葉量과 樹幹內에 存在하는 營養句配와 密接한 關係가 있는 것으로 調査되었다. 2. 垂直方向系列은 年輪幅의 變化가 不規則하여 一定한 生長패턴이 없는 것 같으며, 이는 外部環境要因이 反映된 것으로 생각되며, 年輪幅增減現象으로 보아 林木의 密度에 따라 樹冠競爭의 差가 4年 程度있는 것으로 調査되었다. 3. 水平方向系列은 斜面方向과 垂直方向列의 性質을 함께 가지며, 根源部(X)와 胸高部(Y)의 年輪幅增減現象을 보면 林木의 密度에 따라서 樹冠競爭의 差가 垂直方向系列과 같이 4年程度있는 것으로 調査되었다. 4. 垂直方向과 水平方向系列의 年輪幅增減現象을 보면 密生林(A)은 10年生때, 疎生林(B)은 14年生때 間伐로서 林木의 密度調節이 要求되었다. These studies were carried out to know the growth patterns appearing in annual ring width at different heights and the influence of stand density on growth in annual ring of Pinus densiflora S. et. Z. The results are summarized as follows; 1. The coefficient correlations among the growth patterns appearing in annual ring width of oblique sequence, the volume of leaves in crown and the nutrition slope in stem showed to be high significant by stand. 2. The vertical sequence did not have a peculiar growth pattern owing to be irregular in the variation of annual ring width, and it should be affect on the variation of growth by environment factors, therefore I conclude that the difference of the crown conflict of different stand density was recognized to be period of 4 years by the tendency of the increase and decrease in annual ring width. 3. Horizontal sequence contained both its quality of oblique sequence and vertical sequence, and also the difference of the crown conflict of different stand density was recognized to be the period of 4 years, as it was shown the tendency of the increase and decrease in annual ring width of the part of stump and the position of breast height. 4. The proper thinning time was showed to be the period of 10 years in case of closely spaced stand and the period of 14 years in case of sparsely spaced stand by the tendency of the increase and decrease in annual ring width of vertical sequence and horizontal sequence, and then we should be control the crown density.
