한반도 남부에 분포하는 저수지로부터 규조의 계절별 변화를 파악하기 위하여 마지저수지, 죽토저수지, 월정소류지(남동부), 화영과 화동저수지, 월용저수지(남중부), 원선2제, 장동제와 만년1제(남서부)등 총 8곳으로부터 계절별로 수거한 저수지 퇴적물 시료를 분석하였다. 규조를 분석한 결과, 남동부 지역에서는 우점종으로서 Aulacoseira spp., Fragilaria crotonensis, Fragilaria tenera, Gomphonema gracile, G. parvulum, Gyrosigma attenuatum등이 산출되었다. 남중부 지역에서는 Aulacoseira spp., Cymbella tumida, Cymbella turgidula, Diploneis finnica, Fragilaria crotonensis등이 우점으로 산출되었다. 남서부 지역에서는 Aulacoseira spp., Fragilaria crotonensis, Gomphonema parvulum, Stenopterobia curvular가 역시 우점으로 산출되었다. 산출된 대부분의 우점종들이 청정수역에서 서식하는 종(Saproxenous taxa)들로서 이들 저수지의 수질 환경은 오염되지 않은 수역으로 생각된다. 계절별로 규조의 생산성을 비교한 결과, 겨울철보다 여름철에 더욱 풍부하게 나타나는 것이 일반적이나, 남동부의 저수지들에서는 2월보다 5월에 채취한 시료들에서 규조의 개체수 농도가 낮아지는 특징을 보인다.

조밀하게 채취된 한욱 근해 대륙붕 상의 표층퇴적물의 입도 자료 1.044 개를 재해 석하였다. 이들 표층퇴적물의 입도곡선은 31%가 단일 모르를, 54%가 두 개의 모드를 보이며 나머지는 세 개 이상의 모르를 가진다. 단일모드 퇴적물과 북모드 퇴적물의 각 구성모드의 입도곡선은 대체로 정규분포와 세립질화 한다. 군산 앞바다 및 남해 외대 륙붕의 단일모드 모래지역의 지리적 분포는 중금속 및 부유퇴적물 농도의 최저값지역 과 거의 합치한다. 이상의 사실들에서 퇴적물의 세립질 모드의 입도분포가 현세의 운 반 퇴적과정을 잘 반영한다는 것을 알게되었다. 동시에 모드분석수법이 퇴적물의 입도 자료를 해석하는데 유용한 방법임을 알게되었다.

A significant surface net heat loss appears around the Kuroshio and the Tsushima Warm Current regions. The area where the surface heat loss occurs should require heat to be supplied by the current to maintain the long-term annual heat balance. Oceanic heat advection in these regions plays an important role in the heat budget. The spatial distribution of the heat supply by the Tsushima Warm Current near the surface was examined by calculating the horizontal heat supply in the surface layer of the East/Japan Sea, directly from historical sea surface temperature and current data. We have also found a simple estimation of the effective vertical scale of heat supply by the current to compensate net heat loss using the heat supplied by the current in the surface 10m layer. The heat supplied by the current for the annual heat balance was large in the Korea/Tsushima Strait and along the Japanese Coast, and was small in the northwestern part of the East/Japan Sea. The amount of heat supplied by the current was large in the northwestern part and small in the southeastern part of the East/Japan Sea. These features suggest that the heat supplied by the Tsushima Warm Current is restricted to near the surface around the northeastern part and extends to a deeper layer around the southeastern part of the East/Japan Sea.

This research analyzes factors of family life adjustment in mixed-culture families through a focus group and individual interviews with nine mixed-culture couples eighteen people who live in city C. First, the reason that women of other cultures wants to marry Korean men is because they find it a good opportunity, as they expect that Korean husbands will take responsibility of their family. On the other hand, Korean men also expect that they would have some similarities to each other. Also, in southeastern Asian men have more freedom than women to choose an international marriage in Southeastern Asia. Second, mixed-culture couples in everyday life are affected by communication problems, cultural differences, natural environment, financial situation, male -dominant attitude, self-adjustment pressure, house-work role and financial support from their own country. Third, wives from other cultures ask for social support to adjust in Korea and make a healthy family. These women can be important, as they have their own role in the family even though they may be far from their mother in law's strong expectation in how well she can adopt Korean culture.

How might historians secure for the river a larger berth in the recent macro-historical turn? This question cannot find a greater niche than in the emerging critique of the existing spatial configuration of regionalism in mainland Southeastern Asia. The Brahmaputra, Irrawaddy, Salween, Mekong and Yangtze rivers spread out like a necklace around Yunnan and cut across parts of the territories that are known as South, Southeast and East Asia. Each of these rivers has a different topography and fluvial itinerary, giving rise to different political, economic and cultural trajectories. Yet these rivers together form a connected "water-world". These rivers engendered conversations between multi-agentive mobility and large-scale place-making and were at the heart of inter-Asian engagements and integration until the formal end of the European empires. Being both a subject and a sponsor of transregional crossings, the paper argues, these rivers point to the need for a new historical approach that registers the connections between parts of the Southeast Asian massif through to the expansive plain land and the vast coastal rim of the Bay of Bengal and the China Seas. A connection that could be framed through the concept of Holon.

Examining polychaetous annelids collected from Chinhae Bay in the southeastern part of Korea, I found three species which should be added in the list as new to the polychaetous annelid fauna of Korea. In the present study three species are reported with morphological descriptions. Consquently, it totals 133 species of polychaetous annelids from Korea including those previously reported.

스파커와 12채널 스트리머, 그리고 휴대용 기록기를 이용하여 고리원전 연안에서 탄성파탐사를 수행함으로써 4기 단층의 분포와 특성을 파악하였다. 스트리머의 채널간격은 6.25 m이며 스파커는 500 Hz까지의 음파를 발생시키므로 수평 및 수직분해능이 매우 높은 자료를 얻을 수 있었다. 조사지역에는 한반도의 동남부 해안을 따라 분포하는 mud belt를 구성하는 홀로세 퇴적물이 30-40 m의 두께로 쌓여 있다. 조사지역 전체에서 홀로세와 플라이스토세의 경계를 이루는 반사면은 매우 뚜렷하며 천부가스층의 분포도 확인되었다. 조사지역내에서 다수의 4기 단층들이 발견되는데 이들은 수직에 가까운 경사를 가지며 남북방향으로 연장되고 있다. 이들 단층들은 수백 m의 간격으로 배열되어 있으며 지역적으로 인장력에 의해 형성된 특성을 보여주기도 하지만 대체로 압축력이 우세한 영역에서 형성된 것으로 해석된다. 홀로세 전기동안 해침과 관련된 침식충진 퇴적층으로 해석되는 지층을 자르는 단층들도 지역적으로 발견되었다. Mud belt를 구성하는 퇴적층 내에 분포하는 천부가스는 균열이 생긴 단층면을 따라 올라온 것 같은 양상을 보여주기도 한다. 동해를 형성시킨 지구조 운동이 마이오세 후기 이후 약해졌지만 그 이후에 한반도의 남동연안에서 단층운동이 활발하였음은 아직도 정상보다 뜨거운 맨틀영역에 속하는 이 지역이 지체구조적으로 안정되지 못함을 지시한다.

Background: Cliffs are a major plant habitat around the coastal area, but in contrast to sand dunes and salt marshes, they have been little investigated in Korea. There are simple descriptions of cliff vegetation in studies on island vegetation, but there is no published paper, which addressed sea cliff vegetation synthetically. Furthermore, the coastal area where this study was carried out was designated as a conservation reserve. Even though, this area is exposed to intense recreational use such as trekking in these days. This study aims to clarify spatial distribution and structure of vegetation along the environmental gradient on coastal cliff and plateau in the Janggi peninsula (Homigot) located on southeastern Korea. Further, this study has also another objective to prepare a restoration plan to protect this conservation reserve from intense human disturbance. Results: Landscape elements were arranged in the order of sea cliff risen directly on the sea, seashore, coastal cliff, and plateau covered with relatively deep soil in a coastal area of the Janggi peninsula (Homigot), southeastern Korea. Vegetation was sampled at 59 plots arranged from the sea cliff through the seashore and coastal cliff to plateau. The sea cliff, seashore, and coastal cliff, which compose the coastal landscape, were dominated by the seashore spatulate aster (Aster spathulifolius Maxim.) community, dwarf sand sedge (Carex pumila Thunb.) community, and seashore spatulate aster (Aster spathulifolius Maxim.) community. On the plateau corresponding to the ridge of the coastal cliff, black pine (Pinus thunbergii Parl.) community, golden rain tree (Koelreuteria paniculata Laxmann) community, east Asian hackberry (Celtis sinensis Pers.) community, sawleaf zelkova (Zelkova serrata Makino) community, and Korean oak (Quercus dentata Thunb.) community were established in the mentioned order along distance from the sea. Stand ordination showed a vegetation sequence from the seashore through the cliff to the plateau, consistent in its overall pattern among sites. This was dominated by topography. There is evidence for the importance also of salinity, drought and of soil depth. Conclusion: The lack of scientific interest in cliffs to date is in striking contrast to the commonness of cliffs around the whole national territory and to the attraction cliffs have had for humans throughout history. Cliffs provide a unique habitat, rarely investigated from an ecological viewpoint. Cliffs may represent an invaluable type of ecosystem, consisting of some of the least disturbed habitats on earth and contributing more to the biodiversity of a region than their surface coverage would indicate. Although this coastal area where this study was carried out was designated as a conservation reserve, this area is in danger of severe disturbance due to excessive recreational use. We recommended a restoration plan to protect this area from such a disturbance.
