Fog in Taechon which is located in the west coast of Korea is advection fog made by marine atmosphere which is higher than the temperature of sea water and cooled while moving toward land with wind. Huwevcr. the annual mean number of tog days is 15.1, obviously Icss than those of Susan, Kunsan and similar coastal cities. The number of fog occurrence days in April and May increases twice as many as that of the months from November to March. From August it decreases to half as many as that of the months from April to May and then maintains such an extent. So the phenomenon is different from other areas. 1 he characteristics of fog in Taechon arc due to little difference between sea surface temperature and marine air temperature and geographical characteristics of Taechon area.

We have studies fatty acid composition of water extracts of parts of omija (Schizandra chinensis Baillon) and antioxidant activities of fractionated omija parts (fruits, endocarps, seeds) were determined by DPPH methods and by in vitro hepatic microsomal lipid peroxidation system. Fatty acid composition was not different by parts of omija and major fatty acids are linoleic, oleic, and palimitic acids, among fatty acids is water extracts of parts of omija, linoleic acid was highest in content. Methanol and buthanol fractions of seeds and ethyl acetate fraction of endocarps showed stronger antioxidant activities by DPPH methods. Methanol and buthanol fractions of seeds also showed on inhibitory effect on in vitro liver microsomal lipid peroxidation.

1990년 6월부터 전남지방에서 성훼로몬을 이용한 파밤나방의 발생소장, 일일비산활동 및 기주별 가해특성을 조사한 결과 성충은 6월 중순부터 trap에 유인이 시작되어 11월 하순까지 계속되었으며 발생 peak는 비닐하우스에서 8월 중순~하순, 9월 중순~하순, 11월 상순~중순이었으며 야외포장에서도 역시 6월 중순부터 유인이 시작되어 9월 상순~하순, 10월 중순~11월 하순에 유인량이 많았으며 노지에 비해서 비닐하우스에서 peak가 20일 가량 빨랐다. 유충의 biomass에 의한 발생 가능세대수는 남부지방에서 6회로 추정되었다. 일일중 비산활동은 주로 24시 이후부터 일출전까지 활발하였으며 peak는 4시~6시 사이였다. 기주에 따른 가해특성은 외대파에 있어서는 초장 10cm이하에서 유충 밀도 및 피해주율이 가가장 높았으며, 국화는 생육에 따라 피해주율이 점차 증가하다가 생육후기에는 오히려 떨어지는 경향이었고 가해부위는 시기에 관계없이 주로 엽상이 70%이상이었고 다음은 엽하 12.3%, 정단 9.3%순이었다. 또한 안개초에 있어서 피해주는 거의 생육을 하지 못하여 개화에 이르지 못하였다.

This study was carried out to investigate the effect of the emulsion stability according to the quantity of emusifiers and the pressure of homogenizer in coffee whitener preparation. The results of this study are as follow : 1. To obtain a standard emulsifier, the ratio of mono and diglycerides (Atoms 150), sorbitan monostearate (Span 60) and polyoxylene(20) sorbitan monostearate (Tween 60) was 60 : 20 : 20 and the optimum quantity was about 0.9% for stable emulsion. 2. Characteristics as coffee whitner were markedly improved when the pressure of homogenizer was 200∼250㎏/㎠ and homogenizing times are over 4. 3. The good whitening capacity was showed when fat glouble`s average diameter was under 0.5㎛.

This study was divised to observe an inhibitory toward a lipolytic action of toxohormone-L from large root and small root Nepal pseudo ginseng (NPG : Nepal products) components by water extract and ethanol precipitate in vitro. Toxohormone-L is known to be a lipolytic factor that was partially purified from the ascites fluid of sarcoma 180-bearing mice and of patients with hepatoma. The inhibitory effect that inhibited the lipolytic action of toxohormone-L by ethanol precipitate component of large root NPG(mean 46.8%) was higher (mean 1.8 times) than that of water extract component in final reaction concentration ; 500㎍/㎖, on the other side inhibitory effect of water extract component in small root NPG (mean 43.9%) was higher(mean 1.2 times) than that of ethanol precipitate component, respectively. In a way inhibitory effect of ethanol precipitate component in large root NPG(47.6%), when final reaction concentration of sample were l, 000㎍/㎖, was about 40% lower than that of Korean red ginseng, respectively.

The purposes of this studies were to investigate the effect of dietry Se levels and alcohol administration on the lipid hyperoxidation and the lipid metabolism in the rat. Seventy two male rats of Sprague-Dawley Strain weighting about 58∼62g were divided into 12groups. The dietary Se levels were 10, 0.4 and 0㎎, and the dietary α-tocopherol levels were 150 and 0㎎ per ㎏ diet, respectively. Alcohol-administrated groups received drinking water solution containing 10% of ethanol from the 3-weeks of experimental periods. The obtained experimetal results are summarized as follows. 1. Food intake, body weight gain and food efficiency ratio were significantly lower in H-, L- and alcohol administrated groups(-A) by administrated Se and alcohol in diet. The weight of liver and spleen tended to be greater in H- and alcohol administrated groups. 2. The glutathione values in liver tend to be lower in alcohol or Vit. E administrated groups than nonadministrated groups. Also there were higher in H- and L- than C-groups, but the increasing range decreased due to administrated alcohol. The lipid peroxide values in liver were significantly higher in alcohol groups, and L- and tocopherol groups were higher values. Specially the increasing of lipid peroxide values were significantly effected by alcohol in low Se and Vit. E groups. 3. The contents of total glyceride in plasma were higher in alcohol groups, there were significantly higher values in alcohol administrated groups under low Se and Vit. E groups. The contents of total cholesterol and HDL-cholesterol in plasma were significantly higher in alcohol groups. 4. The contents of total lipid in liver were higher alcohol groups, and slightly higher values in low Se groups(L-groups) than other groups, also higher values in low Vit. E groups. Those of total glyceride in liver were significantly higher in alcohol groups, appeared highest values when alcohol was administrated in low Se and Vit. E groups. The increasing of total glyceride content was significantly effected by alcohol in low Se groups than that in C-groups.

The seeds of wild and cultivated Camellia japonica were studied for their lipid contents and fatty acid composition. The seeds of wild and cultivated Camellia japonica contained 70.2% and 73.4% lipids, respectively. Fifteen fatty acids were identified in the lipids from the Camellia japonica seeds. In addition to confirming the 5 previously reported (16 : 0, 18 : 0, 18 : 1, 18 : 2 and 18 : 3), 10 more acids were characterized. The newly identified acids were 14 : 0, 16 : 1, 17 : 0, 20 : 0, 20 : 1, 20 : 2, 22 : 0, 22 : 1, 24 : 0 and 24 : 1. Both seeds lipids contained 18 : 1 in high levels (81. 6~82. 2%). Little difference in fatty acid composition was noted between the wild and cultivated Camellia japonica seed lipids. The fatty acid composition of commercial Camellia japonica oil was similar to those of the Camellia japonica seed lipids.

A two-dimensional land and sea breeze model has been used for the investigation of the circulation over Cheju Island. The model which has different diffusion coefficients for the heat and for the momentum transfer is subdivided into two layers: the surface layer and Ekman layer. A Z^* coordinate system and non-uniform mesh have been applied for the model simulation. From the model simulation, we were able to conclude that low-level wind was much stronger over Cheju city than over Seoguipo city during sea breeze, and vice versa during land breeze. The sea breeze circulation was distinctive over Seoguipo area, and weak land breeze circulation was seen over Cheju area. Meanwhile sea breeze and land breeze circulations over Cheju and Seoguipo area, respectively, were not found in the model simulation.
