In this paper, Thermally stimulated current(TSC) spectrum was mearsured as a function of formation temperature, formation time, formation voltage and heating rate in a biaxially oriented polypropylene film of thickness 40[μm], which is better than polyethylene in the enduring characteristic against heat and dielectric characteristic, the variation of the TSC was observed by ozone oxidation. This measurment has been carried out in the temperature range from-40[℃] to 140[℃]. As results of the measurment, A,B,C,D peaks was made at 0[℃], 40[℃], 80[℃], 120[℃], respectively. B peak was made at the near second glass transition temperature is estimated the dipole polarization by microbrown motion, C peak is estimated to the polarization of ionic space charge. And, In according to the increase of oxidation time by ozone, B peak increased slowly and C peak increased rapidly after it increased slowly during first oxidation time of 15[Hr]. By initial rising method, activation energies of B,C peaks were calculated to about 0.57, 0.84eV, respectively. The hopping distance and mobility of C peak for pure specimen and ozone oxidated specimen 54A, 71A and 1.099×10??cm²/υ·s, 8. 55×10??cm²/υ·s, respectively.

敎育政策의 實際的 變遷에 관한 實證的 硏究 : 敎育豫算 彈性値 分析을 중심으로

This study aims to expose what is going on in educational policy change at a financial level for thirty years (1960-1990). Based upon this research questions' findings, we enabled to compare the planning with the implementation of educational development programs. To analyze these research questions, this study uses data including educational budget and policy reports made by the ministry of education during 1960-1990. The educational budget data were analyzed with regression models using loglinear transformation. This study finds scale of educational budget to total government budget is a little elastic(elastic coefficient= 1.05). However, in the near future we cannot expect the amount of educational budget to increase as much as we need to make students' educational circumstances at an optimum level. This is because of "small government policy" in the sense of financial scale, which has helped Korean firms to accumulate capital through exemption from many kinds of taxation. We think the policy priority of economic and social development goals(esp. excellence of education) should be readjusted as soon as possible. The most important policy to our ministry of education during the last thirty years seems to increase the equal opportunity of education in terms of access. It is prior to other educational policy goals such as an equal opportunity of educational process, excellence of education etc.. What is surprising is that budget of special education for handicapped to total educational budget is quite unelastic(elastic coefficient =.870). Special education has to be supported more strongly if the ministry of education considers equality of education the most important policy goal. Regarding policy of excellence education, textbook compilation, budget and audio-visual education budget to total budget of the ministry of education are unelastic. Good textbooks and teaching methods are critical for a high quality of education. The ministry of education should concern these areas financially as well as nominally in order to improve the quality of education in an efficient way. Both the budget of vocational education(1.06) and that of social education(1.32) to total budget are elastic. The former seems to be considered very important in an economic sense and the latter in the sense of equality of educational opportunity for non-school population. However, the budgetary amount of vocational education should be increased much more in the near future. If not, the present proportion of highschool students of nonvocational school to vocational school(64 : 36) will not be able to be reverted to nominally aimed proportion(3 : 7). The lack of supply of workers in the Korean labor market today will not be loosened, either. What is more important among this study's findings is a gap between nominal policy goals and actual goals. That is in most educational policy fields we did not find statistically significant differences in terms of educational budget scale between years announced officially to be important and years not announced. These findings prove dual structure between educational planning and implementation. We argue planning and financial allocation to be consistent in order to get rid of educational planning divorced from implementation contexts, or implementation unhitched from some form of planning. Without strong links between the planning and implementation of educational development programs, we cannot achieve programs of educational development efficiently.

This study was conducted to estimate growth of leaf and shoot and flowering as affected by GA3 treatment in vitro. Plant height was longer as the concentration of GA3 was higher up to 2.0mg/l. Stem diameter was thick up to the concentration of GA3 was 0.1mg/l , but become thinner as the concentration of GA3 was higher. Root weight and root length were well developed in GA3 concentration was 0.5∼2.0mg/l. Number of roots was more in GA3 concentration was 0.5 and 1.0mg/l . The first flowering occurred in 40 days after 0.5 mg/l GA3 treatment. As the concentration of GA3 was higher, flowering was delayed. Number of flowering was significantly increased in GA3 concentration was 0.1 and 0.5mg/l. However, it was gradually decreased after 60 days. Percentage of flowering per plant was highest in GA3 concentration was 0.5mg/l , but it was lower as the concentration of GA3 was increased.

The lower leaves shading in upper leaves is unknown to be reduced significantly due to the early differentiation of flower-bud by dark treatment of leaves when growing perilla for harvesting the leaves in the greenhouse during the winter. This study analyzed the effect of dark treatment of leaves on the growth and regulation of flowering, which are closely related with differentiation of flower and amount of leaves. One leaf and 3 leaves per plant were dark treated for 0, 5, 10 days. Plant hight was reduced in 3 leaves treatment, but there was no difference in 1 leaf treatment. Stem diameter was reduced in both 1 leaf and 3 leaves treatments, which was more significant in 3 leaves treatment. Leaf area was reduced when 1 leaf was treated for 10 days, but there was no difference when 1 leaf was treated for 5 days. When 3 leaves were treated, leaf area was no difference between treatments. However, leaf area which 3 leaves were treated was reduced more significantly than that 1 leaf was treated. Seed weight was remarkably decreased when 1 leaf was treated for 10 days, and it was decreased when 3 leaves were treated for more than 5 days.

노통 연관식 폐열 보일러의 최적 설계

박이동,이관종,장영근 成均館大學校 科學技術硏究所 1995 論文集 Vol.46 No.2

This study is to obtain optimized design parameters of waste heat boiler with fire and smoke tube which are widely used to provide process and building heat. The optimum parameters obtained in this study can be used as a guideline for actual. boiler design of this type. The design optimization considered here is to find the most economical dimensions of the boiler considered which results in a minimum cost in producing a unit amount of steam per given period of operation. For this purpose, the first we have to determine what are the main parameters of affecting the total cost of producing a unit amount of steam which is comprised of manufacturing cost of the boiler, operating cost of the fan, etc. For the selected design parameters, we will have to decide the conditions of each parameter which will result in the minimum total cost. For the waste heat boiler with fire and smoke tube under consideration, the major parameters of affecting the total cost are considered to the diameter of the smoke tube and the gas velocity among others. The two parameters selected here are considered for finding the optimum size of the boiler by minimizing the total cost which is a function of the manufacturing cost, purchasing cost of the fan, and the operation cost of the system. Through computer simulation, the optimum conditions of these two parameters are obtained for different boiler capacities and different periods of operation.
