  • The purpose of this study is to find sedimentation patterns variation in Seamangum coastal sea region. Water circulations are calculated diagnostically from the observed water temperature and salinity data and wind data and tidal residual current. There dimensional movements of injected particles due to currents, tubulence and sinking velocity are tracked by the Euler-lagrange method. Calculated sedimentation patters of riverine material are highly similat to the observed ones.

  • The purpose of this study is to find seasonal variation of the water circulation in the Chenbuk coastal sea region. Chenbuk coastal sea is investigated with use of a robust diagnostic numerical model. Water circulations in four seasons are calculated diagnostically from the observed water temperature and salinity data and wind data from Kunsan mereorologcal station.

  • A three-dimensional barotropic model is used to compute meteorologically-induced circulations in the East Sea for monthly, seasonal and annual basis. The computed barotropic responses have shown that in the upper part of the 40$^{\circ}$ North latitude. counterclockwise meso-scale eddies have been formed off Dong Han Man, middle part of the East Sea and sea area between the Siberian coast and Hokkaido throughout the year except summer season. These results are in good agreements with some of earlier schematic circulation diagram.

  • Intraventricular hemorrhage long after successful encephaloduroarterio synangiosis (EDAS) is very rare. The effect of revascularization surgery for preventing hemorrhagic event of moyamoya disease remains controversial. We report a 17-year-old female with intracerebral hemorrhage and intraventricular hemorrahge 10 years after successful EDAS. Even though cerebral vessels angiography showed good collateral circulations without specific weak points, a cerebral hemorrhage could occur in patient with ischemic type of moyamoya disease long after successful indirect bypass operations. Good collateralization of cerebral angiography or magnetic resonance perfusion image after indirect bypass surgery would ensure against ischemic symptoms, not a hemorrhage. And, thus a life-time follow-up strategy might be necessary even if a good collateral circulation has been established.

  • An ichthyofauna analysis of the East Sea using quantitative investigation procedures for latitudinal variations of the species richness and clustering of the species list is presented to illustrate the application of the adopted geographical scaling (less than 1:10,000,000) which provides a principal opportunity for common benthic and pelagic biogeographical zonation. The distribution of both pelagic and benthic marine fish biota at a scale of biosphere (or its major sections) was highly influenced by spatial nonuniformity of hydrological structure associated with the various water circulations and frontal zones. Following zoogeographical zonations were established for the East Sea: Osaka, East Korea, Primorye, North Primorye, Northern East Sea, Uetsu, Tsugaru, Soya and West Sakhalin.

  • Eisenmenger syndrome (ES) is characterized by pulmonary arterial hypertension and right-to-left shunting. The signs and symptoms of ES include cyanosis, shortness of breath, fatigue, hemoptysis, and sudden death. In patients with ES, it is important that the systemic and pulmonary circulations be properly distributed and maintained. General dental treatment is not known to be particularly dangerous. To control pain and anxiety, local anesthetics without epinephrine are usually recommended. However, in cases of difficulty of cooperation, general anesthesia for dental treatment makes the condition worse. In the present case, intravenous deep sedation with propofol and remifentanil was administered for behavioral management during dental treatment successfully.

  • The purpose of this study is to find a variation in traveling patterns of soil and soil diffusion due to construction of the sea dike in Saemangum coastal sea region. Water circulations are calculated diagnostically from the observed water temperature, salinity and wind data, and tidal residual current. Three-dimensional movements of injected particles due to currents, turbulence and sinking velocity are tracked by the Euler-Lagrangian method. Calculated a variation in traveling patterns of soil and soil diffusion due to construction of the sea dike deposited mostly from estuarine area of the Geum River to Gokunsan coastal sea region. This results are believed to be the combined effect of coastal circulation.

The Effect of Variations in the Tsushima Warm Currents on the Egg and Larval Transport of Anchovy in the Southern Sea of Korea (한국 남해의 대마난류 변동이 멸치 난$\cdot$자어의 연안역 수송에 미치는 영향)

  • The relationship between the transport of eggs and larvae of Anchovy (Engraulis japonica) and the oceanic condition in the southern sea of Korea was examined on August and November 1996. In summer (August), when the Tsushima Warm Current is strong near to the coast, the warm waters such as warm streamers from the Tsushima Warm Current intrude into the coastal area, and cyclonic circulations are formed. The warm water intrusions also generate wakes around Komun Island, Sori Island and Koje Island. In the coastal area where the warm water intrusions occur, the nutrients, dissolved oxygen, suspended solid and chlorophyll are concentrated in probably relation to the upwelling concerned with this warm streamer and/or the wakes. Anchovy eggs and larvae are transported to the coastal area by the cyclonic circulations. The hatching and growth of anchovy larvae are increased because of high primary production in the cyclonic circulations. However, as the amount of Copepods which are a main food for anchovy larvae decrease in the coastal area, anchovy larvae seem to move to the Isushima Warm Water area for seeking a prey. In autumn (November), the Tsushima Warm Current is far away from the coast. In this season the warm water intrusions almost disappear, and the small scaled frontal eddies are formed between the coastal water and the Tsushima Warm Water. As the surface water moves towards offshore, few anchovy eggs and larvae were sampled in the survey area. Chemical and biological substances are concentrated in the leftdown sides of the small scaled frontal eddies because of eddy formation.
