The visibility is the one maximum distance which can distinguish the thing about the direction. The visibility makes many influence at hman life(traffic, health, etc.). In this paper recognized an area visibility characteristic and relation of a weather element of a Deagu, Inchon, and Cheju. The spatial and temporal distribution of visibility are exmined over the Daegu, Inchon, Jeju from 1992 to 2001 using data from the Korea Meteorology Administration(KMA). seasonal and temporal visibility distribution, correlation coefficient of relative humidity, cloud cover and daily range with visibility are documented. The visibility showed the highest by the month and by the time graph in cheju. Also visibility and relative humidity showed correlation relation of negative in all area, and visibility and medium-level, lower amount of clouds showed correlation relation of negative. But Summer and autumn showed close to 1 relation of positive. Also visibility and correlation relation by three element showed the highest in inchon and correlation relation of relative humidity showed the highest.

Chungju district is licated in the mid-stream of the Namhan river, where Chungju Multipurpose Dam was constructed in Novemder, 1984, with the result that the increased surface area of the lake caused water to vaporize more than before, and so the fog appearance before and after the Dam showed the charateristic variety of fog as follows: 1. The frequency of the fog appearance per year increased in 25.6 times more than before, the steam fog after the Dam appeared more frequently, and fog remained for 7 hours and 11 minutes longer than before, while the fog-remaining time per fog appearance frequency decreased in 46 minutes. 2. The fog appeared almost at the same time before and after the Dam, but the time the fog disappeared grew one hour earlier after the Dam. 3. 69% of the whole fog appearance was the ill-visualized fog, the visual range 0. The fog appeared most frequently in the west wind before the Dam and in the west-northwest wind after the Dam. 4. There were four types in the fog appearance patterns: the radiation fog, two types of the steam fog, and the radiation-steam complexed fog.

大院君時代의 對歐美關係 硏究

Having taken the reins of government, Taiwonkoon reigned over Lee dynasty with a reformative policy, defeating the king's maternal relatives, and endeavoured to pave a innovatory way, while he abolished the long-age corrupt system. His policy is also an example of a struggle for political power as well as that of the King's maternal relatives. He wilded power on autocratic and mighty adminstration against his polititical rivals who had hold the assembled cabinet. There is a good contrast in the adminstration of these two oponents: Taiwonkoon ruled his country with confidence without any attention to his own honour or popularity, but the maternal relatives with conspiracy and trick. Therefore, it is indisputable that he raised somewhat improved consequences to his reformative policy of home affairs. On the contrary to the home affairs, Taiwonkoon on his foreign policy was so ignorant of the then iuternational affairs and the situations of the world that his autocratic and mighty administration induced to drop rather into the international troubles. What a headless and imprudent blunder his foreign policy was! In spite of his foreign policy must be opportunism in its way, Taiwonkoon has it in contemplation to check the rushing streams of the western influences, standing to the unnegotiable national isolation policy. Judging from personal circumstances, it seems in a way very natural to apply the rigid seclusionism in his foreign plank, by which Lee dynasty brought about the more disorder and misfortune for her foreign policy, necessary for an elastic adninistration. I hereof look over the historical sketches and the relative merits of his inflexible policy, dividing it into some items.

베나르-레일라이형 대류의 형태는 정상2차원, 정상3차원, 비정상3차원 대류로 구분되는데 본 실험은 대류의 발생조건과, 같은 점성의 유체에서 높이별 대류세포의 안정도, 그리고 대류의 운동형태가 각 점성에 따라 레일라이 수 및 프란틀 수에 얼마만큼 의존하는지 분석했다. 위 실험을 통해 다음과 같은 결론을 얻었다. 같은 점성에서 높이가 높아질수록 대류의 형태는 정상3차원 대류에서 비정상3차원 대류로 나타났다. 같은 점성의 유체에서 레일라이 수는 유체높이가 커짐에 따라 증가하고, 유체의 점성이 커질수록 감소하는 경향이 있다. 즉 프란틀 수가 증가할수록 레일라이 수는 감소한다. The form of convection of Benard Reyleigh type is devided into normal two dimension, normal three dimension and abnormal three dimension. This experiment analyzed the stability of convection-cell according to height in viscous fluid lilie the developemental condition of convection and how much the form of convectional movement depends on the Reyleigh number and pandtl number in proportion to each viscosity with the experimental equipment above. We had the following conclusion below from the experiment. In the same proportion of viscosity, the form of convection was changed from normal three dimentional convection to abnormal three dimensional one as the altitude gets higher. It incliues that the number of Ra increases as the heigher of fluids gets higher and that of decreases as the viscosity of fluids increases. In conclusion, the Reyleigh number decreases as the prandtl number.

工業成長과 世界貿易趨勢에 대한 比較硏究(1900-1960)

玉璿鍾 명지대학교 1978 明大論文集 Vol.11 No.-

This article surveys the movement of the world trade over the past half century (about 60 years), with serveral major trends. According to the aim, it seems necessary that we analyse the long-term relationship between industrial glowth and international trade in manufactured goods. Since the intention was to analyse the main tionds in the world trade since the end of last century, it was necessary to consider the economic growth of all the main trading countries. In general, the experience of the industrializing primary-producing countries are separated from and contrasted with those of the industrial countries of Western Europe, North America and Japan, and-wherever possible-with those of a selection of less-developed countries which have not yet begun to industrialize to some extent, also, the development experiences of some of the present Industrial countries in the early years of this century may be a pointer to how some of the present primary-produring countries might develop in the future, though clearly much caution is needed before any conclusion can be drawn from the analogy. The method of approach has thus been to attempt to explain the trends in the world trade in manufactured goods by industrial and economic changes in the main importing countries. Such changes are not, of course, the only factors influencing trade; in certain periods, other factors-changes in the terms of trade, or in foreign demand conditions, for example-may be the major influences. The outstanding analytical problem is to eliminate, if possible, the influence of such extraneous factors, so that the net effect of industrial growth on imports can be adequately assesed. Since the imports of manufactures into both the industrial and primary-producing countries are supplied very largely by the industrial countries themselves, the analysis of import trend is, in effect, an explanation of trends in exports of manufactures from the industrial countries. Nextely, a objective has been to analyse the trends in exports from each of the main industrial countries separately. The industrialization of the primary-producing countries has resulted not only in a shift in the pattern of their import trade which has affected all the industrial countries generally; it has also resulted in a substantial degree of import-substitution which has adversely affected the export trade of some of the industrial countries much more than others. Here it is necessary to distinguish the effects of such import-substitution from the effects of competion between the industrial countries, and from the indirect effects of industrialization on imports through its effects on real incomes. Now finally, lets outline the conclusion of this article about the trends of world Trade. First, the long-term movement in world trade in manufactures has been closely related to that in world manufacturing production. There was a break in the relationship in the 1930's, but in historical perspectives this appears as a discontinuity due to special factors (i.e.trade and currency restrictions) operating to depress the level of trade in that period. Second, the depression in world trade volume in the 1930's and the expansion in the 1950' was largely in manufactured goods. Before the second World war, a relative increase in the volume of trade in manufactures, compared with primary products, was nomally associated with a reverse movement in the relative prices of these two groups. Since the second World war, however, a relative expansion in the volume of trade in manufactures has been accompanied by a net increase in the prices of manufactures in relation to an average of primary product prices. Some of the possible reasons for this change have been set out earlier; Third, in the trade expansion of 1950's, the intra-trade of the industrial countries increased faster than any other rector of world trade. This was, in part, a reversion to a more nomal relationship between the intra-trade of the industrial countries and their total output of manufactures. Within the total intra-trade, however, the several streams of trade showed very different long-term tendencies. The most dynamic sectors have been the internal exchanges within the two industrial Continents, that is, the trade between Canada and the United States on the one side, and that among the Continental countries of Western Europe on the other. Trade between the industrial continents has increased at a slower pace. Of exports to outside countries, those to semi-industrial countrieshave tended to rise at a substantially lower rate than those to non-industrial ones. Fourth, against this background of secular expansion, the imports of manufactures into three important trading countries-Britain, India and Argentina-have tended to stagnate over the greater part of the period covered in this analysis, thus helping to retard the rate of growth in world trade. It was not until the late 1950's that imports of manufactures into Britain and India began to rise substantially. For Britain this was partly due to liberalization of import restrictions; while for India it reflected in the main an increase in inflow of aid and long-term capital. Imports into Argentina varied in an erratic manner from year to year in the late 1950's. The long period of stagnation in imports into India and Argentina did, howerer, appear significant at the time since they are also important examples of industurializing primary-producing cournties. Their experiences thus appeared to support the view that industrialization in such countries necessarily tends to restrict exports, and so limits the increase in imports which can be achieved.

氣候란 여러 氣候要素를 綜合的으로 나타낸 것이다. 그리고 氣候要素는 地形, 海拔高度, 海流 등의 여러 氣候因子에 의하여 決定이 된다. 본 硏究에서는 東海岸에 平行하게 뻗은 太白山脈을 境界로 嶺西地方과 嶺東地方의 氣候要素 差異를 20 년 간 月, 年平均하여 比較하고 氣候因子를 토대로 差異 原因을 分析하였다. 그 結果 太白山脈을 境界로 푀엔 現象, 東海岸을 흐르는 暖流의 影響 등으로 氣溫, 降水量, 蒸發量 등의 氣候要素 差異를 發見할 수도 있고 그로부터 相對濕度 差異를 알 수 있었다. 또한 摩擦力의 差異로 內陸보다는 海岸의 風速이 强한 것도 알 수 있었다. 또한 두 地域의 資料를 回歸分析을 통하여 變化量을 알아본 결과 風速, 嶺東의 蒸發量을 除外하고는 모든 要素가 약간씩 增加하는 것으로 나타났다. 아울러 우리 人間들의 무분별한 行動으로 인하여 환경 汚染이 深刻하다. 또한 그로부터 생기는 氣候變化에 좀더 많은 硏究가 필요하고 그 對策이 講究되어야 할 것이다. The climate is dependent on the particularities of such several meteorological elements as geographical features, height above the sea level, and the sea currents. This study focused on analyzing the differences of the climates between the Eastern and Western areas, which are devided by the TAEBAEK Mountains, paralleled with the Eastern seashore. The meteorological elements of the two areas are compared on the basis of the monthly and yearly mean. This study found the two areas showed the differences in the temperature, the amount of precipitation, the amount of evaporation, with the results of Foehn Phenomenon and a warm current in the East Sea. It also found that the two areas differed from each other in the relative humidity, and the velocity of the wind in the Eastern seashore was higher than that in the inland area, due to the difference in frictions. The meteorological data of the two areas were comparatively analyzed in a regression, and showed that all the climate elements, only with exceptions of the velocity of wind and the amount of evaporation in the Eastern area, have been increased and heightened. A further study is highly needed about the changes of meteorological elements, which seemed to have been resulted from the environmental pollution, due to the thoughtless behaviors of people. And it is sincerely hoped that wise measures against the meteorological elements changes should be worked out very soon.
