This paper aims to describe the characteristics of snowfall between Youngdong region and west seaside district at Honam region in Korea. Snowfall datas for Gojin, Kangnung and Samchok where located in Youngdong region and Kwangju, Kunsan and Magilsan adjacent to Sosan where located in west seaside district at Honam region. For this study, it was investigated secular variation of snowy days and snowfall, the monthly occurrence frequency of snowy days and snowfall, and pressure pattern governing snowfall at two regions. Especially, for the cases study of heavy snowfall day, it was investigated mixing ratio field by using the upper air data, which composed of 33 stations and nephanalysis by using GMS picture data. The results were summarized as follows ; 1) Annual mean occurrence frequency of snowy days were about 32.1days in west seaside district at Honam region and 20.0days in Youngdong region, respectively. The order of monthly occurrence frequency of snowy days and snowfall were Jan., Dec., Feb. and Mar. in west seaside district at Honam region, and Feb., Mar., Jan. Dec., in Youngdong region, respectively. The secular variation(1980-1990) of snowy days and snowfall showed increasing trend. 2) The pressure patterns governing snowfall in Honam region were classified broadly into three types ; 1. cP dominant type, 2. Through or Low dominant type 3. Cut-off High type. The pressure pattern which had the most occurrence frequency of snowy days and snowfall was cP dominant type. And the pressure patterns governing snowfall in Youngdong region were classified broadly into two types ; 1. cP dominant type, 2. NE air flow type. The pressure pattern which had the most occurrence frequency of snowy days was NE air flow type, which the most snowfall was cP dominat type. 3) On the heavy snowfall day, the moisture layer existed below 850hPa in west seaside district at Honam region and below 700hPa in Youngdong region, respectively. 4) In the mixing ratio field on the heavy snowfall day, the moisture tongue existed at both SFC and 850hPa level in case of heavy snowy day of Youngdong region and the meridional gradient of mixing ratio at SFC at South region in west seaside district at Honam region.

This study analyzes the diurnal, seasonal and annual variations of TSP in Kwangju and investigates the relation of TSP to air temperature and to RH. The data used in this study are observed from Meteorological Office and Environmental Bureau in Kwangju and the period of observation was from Jan. 1, 1991 to Dec. 31, 1993. The diurnal variation of TSP shows two vibration curves and the diurnal means are 67.9㎍/㎥. The time the diurnal maximum value is shown is 10:00 A.M. and that diurnal minimum value is shown is 06:00 A.M. The diurnal range is 55.9㎍/㎥. In this diurnal variation of TSP by season, the concentration is high in winter, spring, autumn and summer in order. The annual variation of TSP shows one vibration curve, the maximum value in April and the minimum one in August. The annual range is 43.6㎍/㎥. As a result of the regression analysis for examining the relations of TSP to air temperature and to RH, a regular polynomial regression expression is made on time series. TSP has a great significance in the diurnal variation with air temperature, but it has a little significance in the annual variation. TSP and RH have a significance in the diurnal and annual variation and show the inverse propertion with them.

This paper is a study on the distribution of the climatic elements, characteristics of change and correlation among the meteorological variable in the Chollado area. For this study the MONTHLY WEATHER REPORTS over the last ten year(1971~1980) were u^tilized. Weather station were nine in number, those of Kunsan, Puan, Chonju, Cho^ng-up, Imshil, Namwon, Kwangju, Hampyong and Mokpo. The meteorological variable include relative humidity, evaporation, precipitation, air temperature, etc. As the result of this study, each climatic element showed the same aspects of change. During the summer, relative humidity, evaporation and precipitation, and air temperature reached their highest points, and wind speed, wind direction and diurnal temperature range fell to their lowest points, and the highest point appeared two times. The values of the climatic variables differed greatly among the different observatories. Integrated interpretation is also needed because there is more or less correlation among all the meteorological elements.

This paper is to analyse the period and variation of the temperature of the atmosphere and sea water with respect to seven observation stations selected on the southern, eastern and western coasts of Korea. The results are as follows; Sea water temperature changed more slowly then atmosphere temperature, and it is smaller in relation to the amplitude(A). It shows that the correlationship was very strong because the correlation coefficient between atmosphere and sea water temperature appeared very close to (A). The regression equation of atmosphere and sea water temperature can be expressed as Ti=a_1+a_1cos Di+b_1sin Di. The time gap that shows the minimum temperature of atmosphere and sea water was much longer than that of their maximum temperatures, and it was the longest at the northern observation stations. The minimum temperature of sea water occurred earlier than that of atmosphere in Kunsan. The amplitude of sea water temperature on the eastern coast was much smaller than that on western and southern coasts. The maximum temperature of sea water in Wolmido was higher than that of atmosphere, and the minimum temperature of atmosphere in Kunsan was higher than that of sea water. To interprete the particular phenomena above the autocorrelationship according to the oceanity and the continentality was worked out so that the only correlation coefficient between oceanity and minimum temperature of sea water showed 0.93, and that between others was below 0.3. Therefore, it must be interpreted in relation to other factors.

This paper is a study on the characteristics of RH variation in the urban area (in Seoul and Kwnagju). air temperature, RH and precipitation are meteorological elements observed from January 1, 1991 through December 31, 1991. The research contents of this study are distribution of variance, regression equation, annual variation, seasonal variation, diurnal variation and Dry Index. The results are as follows : Correlation coefficient of air temperature and RH is -0.91, and regression equation is RH=115-0.31T. Variation of RH has one annual cycle, which shows low RH period (spring and autumn) two times a year. It is shown that RH of urban area is lower on an annual average mean 2∼5.5% than that of surrounding area. Distribution of seasonal RH is in the order of winter>summer>spring>autumn. The order of seasonal RH difference between urban and surrounding area is autumn>spring>summer>winter. The paper shows that during one day RH at night is higher than that in daytime, and the order of RH difference between day and night is spring>autumn>summer (winter)>winter(summer). It is observed that during one day the highest RH occurs at sunrise time and the lowest, at 3 p.m. The distribution of Dry Index and RH are nearly similar.

A 13-year-old, castrated male, Maltese-dog was admitted to the Veterinary Medical Teaching Hospital of Chungnam National University with the history fo petechiae. On physical examination, she had petechiae and ecchymoses at her back, bilateral inguinal region, and inner part of ear pinna. CBC indicated neutrophilia and severe thrombocytopenia. A few platelets, no autoagglutination of RBC, and no spherocyte were observed. Coagulation profile demonstrated normal PT, and aPTT. No significant findings was not found on serum biochemical profile and electolytes test. FNA of a splenic mass which was found on the abdominal radiograph and sonograph demonstrated extramedullary hematopoiesis, Proteinuria was observed on urinarysis. Primary immune-mediated thrombocytopenia was diagnosed by ruling out of other underlying disease, severe thrombocytopenia, and response to immunosuppressive therapy. Prednisone and antibiotics were administered orally and parenterally, respectively. After altering prednisone to azathioprine, the number of platelets was recovered to normal range and petechiae and ecchymoses were improved.

To explain quantitatively the statistical characteristics of typhoons on the south-western coastal areas of Korea, this paper mainly deals with the phenomena at Mogpo area. The sources of applied data chiefly are those of 'Typhoon report of Korea', 'Annual climatological report of Korea' (published by Korea central meteorological office) and 'Annual tropical cyclone report'(by J.T.W.C.). The quoted data are those observed during 86 years, from 1904 to 1989. The main contents are about the analysis of frequency, monthly distribution, location, track, intensity, accompanying wind, and arrival period. According to the analysis, the total number of the typhoons influencing the southwestern coastal area is 136 times. It comes under 5.5% of all. Monthly frequency centered on the months between July and September, 128 times which is 94% of all. Especially it occurred most often in August(57 times). Most of the typhoons occurred in 10∼20˚N and 125∼150˚E areas. The location of occurrence changed variously during a year. Generally occurred in lower latitudes and approached toward the northern areas. But it turned to the southern area again after September. It moved from the west to the east in the longitude. The track of typhoon drew the slow curve in earlier seasons, beginning in the westward of the lower latitude, and the quick curve in later seasons, beginning in the eastward of the higher latitude. The point of recurvature changed from the westward of lower latitude to the eastward of higher latitude and finally to the westward of lower latitude. The intensity of all the typhoons acting at Mogpo was under C class, often accompanied with over 80mm rainfall. The direction of winds is conspicuous in S direction series, but often N direction series appeared in May, June, and November. On the average it took 7 days for the typhoon to occurrence and arrive in Mogpo area.
