楊辰錫 淸州大學校 1980 論文集 Vol.13 No.1

In the rainy season from June to September, the amount of rainfall is normally about 61 percent of the total annual rainfall in South Korea. I noticed that the daily amount of rainfall is distributed variably. When it rains over 80㎜ in a day, I defined it as a heavy rainfall. In general these heavy rainfall caused terrible damage to human life. The aim of this study is to recognize clearly the regional distribution of the heavy rainfall and its relationship to high value, and what is its factor in the rainy season in South Korea. The results of my investigation may be summarizedas follows: 1. The frequency of heavy rainfall goes up its peak in July, and during that time the rain front occurs frequently. But since after that it decreases in the order of August, September and June. And so its monthly precipitation does. 2. Regional distribution of heavy rainfall related to the movement of the extratropical cyclone and the changma front (the rain front). The maximum frequency of heavy rainfall appears differently according to the region, that is, it appears in June in southern part, in July in northern part, in August in northern and southern part, and in September in east coast. 3. The correlation between the distribution of heavy rainfall and high value is very close except August. The regional distribution of the heavy rainfall in the rainy season is nearly coincided with that of the high value. 4. Most of heavy rainfall is due to the extratropical cyclone, changma front and Typhoon. The heavy rainfall caused by extratropical cyclone most frequently appeared in June and September, and the changma front do in July.

The Korean Peninsula is located on the east coast of Asia, where the monsoon climate appears and results in a great variation of spatial and temporal distribution of precipitation. Precipitation is a important climatic element of Korean Monsoon phenomena, and the amount of rainfall during summer has a large impact on national economy in Korea. Precipition is resulted from moisture supplies through the convergence of moisture transport. Therefore understanding of the distribution of precipitation needs the investigation of moisture distribution over East Asia. The purpose of this study is to identify the characteristics of moisture distribution over East Asia during drought and wet periods of summer in Korea. The results of this study may be summarized as follows : 1) In surface pressure field during drought period of summer in Korea, the dew-point depression of Korean Peninsula are 3℃ to 6℃. In contrast, the section of moist air which dew-point depression is under 3℃ apears during wet period over Korean Peninsula. 2) The moisture distribution of the surface pressure field in South Korea is characterized by a greet variation of monthly and regional distribution. Especially drought periods make higher regional difference than wet periods. 3) In regional distribution of moisture, inland areas of southern part in Korea have lowest value of humidity. It coincides with the minimum rainfall area in Korea. 4) In distribution of dew-point depression of 850mb surface around Korean peninsula, drought period has 2℃ to 3℃ higher than wet period, whereas the section of moist air which dew-point depression is under 3℃ appears over the Korean Peninsula during wet period. 5) The shapes of the sections of moist air which appear over Korean Peninsula during wet periods of summer are tongue type or zonal type. This moisture is supplied from southern side or southwesthern side along the perimeter of the westhern edge of the subtropical high.

This paper employs the equilibrium approach to exchange rate determination model(Stockman, 1987) and the Sims' innovation accounting technique to asses the relative contributions of the determinants of the foreign currency(U.S. Dollar, Japan Yen) value in terms of the Korean Won. Monthly data during the period January 1980 through December 1990 are used in the analysis. Unlike the monetary approach to exchange rates, the equilibrium approach may incorporate the purchasing power disparity as a determinant of the nominal exchange rate. Furthermore it argues that any government policy can not create the correlation between changes in the real and nominal exchange rate. This may imply that the change in the nominal exchange rate in duced by government policy can not affect the real exchange rate. Causality runs from the change in the real exchange rate to the nominal exchange rate. For U. S. vs Korea VAR system, the real exchange rate is affected by the relative money supply ratio and the relative production ratio at the significance level of 8% and 10 % respectively. On the other hand the nominal exchange rate is affected only by its own past. The variance decomposition result is that the innovations in the real exchange rates(deviation from the relative purchasing power parity) may account for about 55% of the forecast error variance in the nominal exchange rates. In contrast, the innovations in the nominal exchange rate may explain 8% of the forecast error variance in the real exchange rate. For japan vs Korea VAR system, the causality test is that both the real and nominal exchange rate are completely autonomous. the variance decomposition result is that the real exchange rate may account for about 67% of the forcast error variance in the nominal exchange rate. On the contrary the innovations in the nominalexchange rate may explain 7% of the forecast error varaince in the real exchange rates. To sum, the change in the nominal exchange rate is caused by the nonmonetary factors, such as the presence of the nontradables, trade restrictions, government spending. In contrast, the change in nominal exchange rate induced by the government policy can not affect the real exchange rate.

In this paper, I have attempted to clarify the regional distribution and variation of the extreme values of precipitation over South Korea as well as the correlation between the high values and low values of precipitation in May. The conclusion of this study may be summarized as follows: 1. The range of regional distribution in high values are 160-300㎜, and low values are 20-40㎜. It shows the high difference of regional distribution. The location of regional distribution of the largest values in extreme values is Southern Coast, the lowest of high values appears in Central part, and the low values is Northwestern part, therefore, its result shows South-high North-low patterns. 2. The Coefficients, of variation in high value are 15-45%, and low value are 15-55%, which is showed the high difference of regional distribution. In the regional distribution of coefficient of variation, the largest in extreme values appears in the North-western part, whereas the lowest of high values appears in Southwestern inland, and low values in Southern coast. It reflects well North-high South-low penomena. 3. For the regression coefficient of regression equation of high values to low value is large, high values are changed rapidly according to the variation of low values. 4. In the correlation between the extreme values, mean value and extreme values, correlation coefficients indicate very high degrees of positive correlation, and mean value shows the high and low degree of the extreme value.

楊辰錫 淸州大學校 1981 論文集 Vol.14 No.2

The season of Korea has clearly been divided into a rainy season and a dry season, and the rainy season brings us for the most part heavy rainfall or sometimes .drought which cause us a great disaster. The objectives of this study are, first aimed at surveying the amount of precipitation which is over 80mm in a day from June to September, second, aimed at surveying the regional distribution of monthly high value and finally at studying the correlation between heavy rainfall and high value. The results of the study may be summarized as follows: 1. The highest value of heavy rainfall and high value appears in July and the order of the value is August, September and July. The reason why the highest value appears in July that the month has the peak of Changma front and it has the highest frequency of the passage of cyclone in our country. 2. It has been verified that the highest value of heavy rainfall and high value in June appeared in the south-east coast and in July the highest value appeared in the north-west part of our country, and this phenomenon shows us that heavy rainfall and high value coincide so well that the place of the highest value and the location Changma front have a colse relationship. 3. The distribution of the heavy rainfall of August shows that it has the highest value both in southern and northern parts locating its lowest value in the central part of our peninsula. The reason why the south-east coast has the high frequency of heavy rainfall in September is explained by the fact that the south-east coast has a certain relationship with the passage of annual Typhoon. 4. Heavy rainfall and high value are highly correlated, and this shows that while June has the highest correlation, September has the lowest one. 5. The island Ulleung, which is located far from the peninsula, has the lowest value between heavy rainfall and high value in a rainy season

In this study, Pt supported on MCM-48 was tested as a new catalyst for hydrocarbon-SCR process. MCM-48 is a new support material of the catalyst fur SCR. Characterization and de-NOx activity test were performed for the newly synthesized MCM-48-supported catalysts. Pt(1wt%)/MCM-48 showed 90% of NO reduction between 250-500℃. Water addition effect was also studied. Water vapor of 10Vol% was injected to the reactor. Water did not exhibit a bad influence on the catalytic activity. This result proved that Pt/MCM-48 had higher water resistance than zeolite. We could expect that metal supported on MCM-48 might be a highly possible candidate fur a new catalyst of hydrocarbon SCR process.
