西歸浦 앞바다에 流入되는 陸水는 2m未滿의 얇은 版狀으로 海水위를 덮고 있고, 이 陸水때문에 만들어지는 沿岸水는 鳥島와 蚊島의 中間에서 森島를 잇는 線까지 擴張하여 이곳에서 外海水와 현저한 潮境을 만들며 이 潮境의 外海쪽에는 過流가 자주 나타난다. 이와같이 海況이 西歸浦 앞바다에 많은 回游性 魚類를 集合시키는 原因이 되는 것 같다. The freshwater being inflow in the sea off the Seogwipo diffuse above seawater with thin layer less than two meters and the coastal water off the Seogwipo formed by influence of freshwater is extented to the line connected between Sam Do and the middle point between Mun Do and Jo Do. Accordingly, the sharp discontinuous line of salinity appear in the out side edge of the coastal water and eddy current, frequently occur in offshore of Seogwipo that is out side of the discontinuous line. Many pelagic fish seem to aggregate in this area bacause of these oceanic conditions.

Currents are measured in the Straits of Cheju by detecting surface buoy tracks and mooring current meters in 1996-1997. As a result, north-eastward currents are decteted in the Straits of Cheju all the year round, which is weak in spring and strong in summer and fall. Average speeds of 20 cm/s to the east. 7 cm/s to the north and 22 cm/s to the north-east appeared in the surface. Currents are fast in the middle of the strait and slow near Cheju Island. East-west components of the currents are about 3 times faster than the north-south ones. Also. it is shown that surface buoys released within the distance of 6 miles away from Cheju do not drift out of the Straits of Cheju because of tongue-like warm waters appeared in the eastern entrance of the strait. Volume transports calculated by geostrophic calculation are shown to be 0.05-0.2 Sv in winter and 0.4-0.5 Sv in summer.

濟州道 沿岸의 水溫 鹽分 變動에 關한 硏究-Ⅰ : 一般的인 變動의 傾向 The tendency of the general fluctuation of temperature and salinity

盧洪吉,鄭公炘 제주대학교 1976 논문집 Vol.8 No.-

The tendency of the general fluctuation of coastal sea surface temperature and salinity in Jeju Island is investigated to get knowledges about the characteristics of the surrounding waters of Jeju Island. The reaults obtained are as follows; 1. The coastal surface water of Jeju Island is covered by Tsushima Warm Water mass through a whole year but the phenomenon of low temperature appear occasionally due to the extension of the Yellow Sea cold water, the occurrence of wind wave and the development of upwelling. 2. The mean minimum temperature which occurs from the late in February to the middle in March is 12.5℃ at the shore sation of Sanji and 14℃ at the shore sation of Seogwipo. The mean miximum temperature which occurs in August is 25℃ at the shore station of Sanji and 27℃ at the shore station of Mara-Do. The irregular variations of the coastal sea surface temperature appear before and after the occurrence time of mean maximum tempenature. However, the most stable season of the coastal sea surface temperature is the spring. 3. Analyzing the varied aspect of the surface water temperature at Sanji and U-Do, it suggests that anticyclonic current may occure in the channel of Jeju in summer. 4. Mara-Do and U-Do are the important shore sation that the former can use to study about the extension of the Yellow Sea cold water and that the latter can use to study about the variation of the strength of the Tsushima Warm Current. 5. The occurrence time of the maximum air and water temperature coincides well because the variation of air temperature influence directly the variation of water temperature at the same time or less than ten days. 6. The minimum salinity at the each shore station in Jeju Island is the range of 27.30-29.00 0/00and it occurs from the late in August to the early in September because of the difference with location. 7. The variation of salinity in the coast of Jeju Island coincides well with the variation of the precipitation in Jeju Island and particularly, the phenomenon which of salinity deerease rapidly in summer is principally caused by the decrease of salinity in the off shore of Jeju and inflow of great quantity of land water from Jeju Island. 8. One of the characteristics of the coastal sea condition of Jeju Island is the rapid fluctuation of temperature and salinity in summer.

1979年 11月 初旬에 西歸浦 앞바다 海水의 營養鹽類 濃度分布를 調査한 結果는 다음과 같다. 1. 蚊島와 森島를 연결하는 곳을 境界로 沿岸쪽은 各種 營養鹽類의 含量이 높고 鹽分이 낮은 沿岸水가 5m이내의 表層에 한해서 存在하고있다. 2. 沿岸水와 外海水가 만나는 境界域 에서는 강한 鉛直 混合이 이루어지고 있다. 3. 西歸浦 앞 바다의 營養鹽類의 濃度는 他지방 海域에 비하여 별다른 差가 없다. 끝으로 本 硏究調査를 하는데 實驗을 도와 준 硏究室의 黃善建, 康京壽, 李景燦君 기타 여러분께 감사를 드립니다. The concentrations of chemical conostituents of seawater at Seogwipo area were determined in early November 1979. The coastal seawater which has high concentration of nutrients and low salinity were found in the depth between surface and 5 m layer. This water mass were distributed from the coast line to the line connected MunDo and Sam Do. Vigorous vertical mixing of water could be observed in this boundary area that the coastal seawater and open seawater were met.

Keratins are characteristically present in all keratinizing and nonkeratinizing epithelial cells and their neoplasms. They consist of at least 19 different polypeptides ranging from 40 to 69 kilodaltons, which are developmentally related to specific epithelial cell types. Keratins of high and intermediate molecular weights are readily demonstrated in squamous cell carcinomas, which are characteristically rich in tonofilaments and tonofilament-desmosome complexes. Keratins of low molecular weights are expressed in adenocarcinoma including renal cell carinoma, hepatocellular carcinoma, small cell carcinoma, and carcinoid tumor. These tumors do not reveal any tonofilaments and sacrcely show discrete filaments on electron microscopy. An immunoperoxidase technique employing antibody to keratin was used to study distribution and staining pattern of keratin filaments in benign and malignant epithelial tumors (20 squamous cell carcinomas, 20 gastric adenocarcinomas, 20 transitional cell carcinomas and 15 non-neoplastic epithelia). These immunohistochemical results were compared with ultrastructural features of neoplastic diagnosis of squamous cell carcinoma, adenocarcinoma and transitional cell carcinoma, and estimation of degree of differentiation. The results are as follows : 1. The squamous epithelium, glandular epithelium and transitional epithelium disclosed the positive reaction for keratin. 2. Squamous cell carcinoma and transitional cell carcinoma exhibited positive reaction for keratin. 3. Gastric adenocarcinoma showed uniformly negative or weakly positive reaction for keratin. 4. On electron microscopy, heavy bundles of tonofilaments and desmosomes were more frequently encountered in well differentiated squamous cell carcinoma, In poorly differentiated squamous cell carcinoma, a few tonofibrils and desmosome were noted. 5. In the adenocarcinomas, the intermediate filaments were arranged randomly as nonaggregated, short filaments spread throughout the cytoplasm, although occasionally they formed a perinuclear whorl. These filaments did not become aggregated to form tonofilaments. 6. On the immunogold labeling for keratin of low molecular weight areas in gastric adenocinoma, in tense labeling of intermediate filaments for keratin was noted. From the above result, ultrastructural and immunohistochemical study on malignant epithelial cell were useful in differential diagnosis of squamous cell carcinoma, adenocarcinoma and transitional cell carcinoma, and estimation of degree of differentiation. It was also proved that immunogold labeling technique was especially valuable for diagnosis of vague case which showed negative or weakly positive reaction in immunohistochemical stain.

Field survey for oceanographic conditions and the seasonal succession of phytoplanktan were carried out in the Hamdok port from April 1989 to February 1990. Water temperature ranged between 11.4℃ in January and 27.3℃ in August, and salinity fluctuated greatly, with a maximum of 35.6960 in August and minimum of 21.8% in April. A total of 120 species of phytoplankton belonging to 69 genera were observed in which, at least, 8 genera, Oxyphysis, Amphidinium, Cochlodinium, Torodinium, Nematodinium, Katodinium, Ebria and streptoheca are first records in the Cheju coastal waters. The predominant species are centric diatoms. Skeletonema costatum, Chaetoceros spp. through the year, while they are unarmoured phytoflagellates, Heterasigma akashiwo, Gymnodiniurn sp., Gyrodinium sp. in warmer seasons. And phytoplankton cell number fluctuated between 4.1~10^(3) cells/l in winter and 2.4~10^(4) cells/l in spring blooms, and it was under the control of centric diatoms for a year. On the other hand, it is occupied by phytoflagellates including some unarmoured dinoflagellates in summer season.
