This study tried to produce an uplift rate map and reveal the spatial distribution of the rate with topographical characteristics and absolute ages on marine terrace in the East Coast of the Korean Peninsula. Based on a total of 57 ages at 26 sites from previous study and 13 ages at 13 sites from this study, the coast showed the rates ranging from 0.145 m/ka to 0.410m/ka with an average of 0.258 m/ka. The highest and lowest rates were found from the Jeongdongjin area in Gangneung and the Goraebul area in Yeongdeok, respectively. However, some areas in the coast showed large differences in the rate among the sites. In addition, areas with only 1 age were also found, indicative of low reliability. This study suggests that a more reliable and precise interpretation on the rate can be made with more ages identified, especially in Goseong to northern part of Gangneung, middle and southern parts of Samcheok and Yeongdeok, southern part of Pohang to northern part of Gyeongju, and Ulsan.

In this study, the effects of polymer concentration and additive in the formation of asymmetric nanofiltration (NF) membrane were evaluated. The membrane fabrication was carried out via dry/wet phase inversion technique. A new formulation of dope solution with polymer concentration ranging between 17 wt% to 21 wt% and the present of additive was developed. The results show that the permeate flux gradually decreases as polymer concentration increased, until $2.5969L/m^2h$ and increased the rejection up to 98.7%. Addition of additive, polyethylene glycol 600 increased dyes rejection up to 99.8% and decreased the permeate flux to $3.6501L/m^2h$. This indicates that the addition of polyethylene glycol additive led towards better membrane performance. The morphological characteristics of NF membrane were analysed using a Scanning Electron Microscopy.

Analyzing the results of East Sea Regional Ocean Model using a 3-dimensional variational data assimilation scheme, we investigated spatial and temporal variability of the North Korean Cold Current (NKCC) in the East Sea. The climatological monthly mean transport of the NKCC clearly shows seasonal variation of the NKCC within the range of about 0.35 Sv ($=0^6m^3/s$), which increases from its minimum (about 0.45 Sv) through December-January to March, decreases during March and May, and then increases again to the maximum (about 0.8 Sv) in August-September. The volume transport of the NKCC shows interannual variation of the NKCC with the range of about 1.0 Sv that is larger than seasonal variation. The southward current of the NKCC appears often not only in summer but in winter as well. The width of the NKCC is about 35 km near the Korean coast and its core is located under the East Korea Warm Current. The North Korean Cold Water (NKCW), characterized by low salinity and low temperature, is located both under the Tsushima Warm Water and in the western side of the maximum southward current of the NKCC that means the NKCC advects the NKCW southward along the Korean coast. It is revealed that the intermediate low salinity water, formed off the Vladivostok in winter, flows southward to the south of $37^{\circ}N$ through $2{\sim}3$ paths; one path along the Korean coast, another one along $132^{\circ}E$, and the middle path along $130^{\circ}E$. The path of the intermediate low salinity varies with years. The reanalysis fields suggest that the NKCW is advected through the paths along the Korean coast and along $130^{\circ}E$.

동해안굿은 대한민국의 동해안 일대 해안선을 따라 강원도 고성 일대에서 부터 부산지역에 이르기까지 어촌마을에서 행해지는 굿이다. 동해안굿은 거의 세습무를 중심으로 연행되는데, 이 논문은 동해안굿의 세습무 집단 중 김석출 무계의 학습 양상을 세습무와 학습무로 구분하여 살펴보고 이를 토대로 변화하고 있는 동해안굿 학습 양상이 가진 의미를 규명하는 데 의의가 있다. 세습무는 집이 곧 교육 현장이었다. 어릴 때부터 굿판에 따라다니며 소리며 춤을 연행하게 해보아 실전경험을 쌓을 수 있었다. 그러나 대를 이어 무업을 계승해오던 세습무 가계에서 더 이상 자손들이 무업을 이어받지 않게 되면서 무업의 계승과 학습 방식에 변화가 발생했다. 1980년대 이후부터 굿이 가, 무, 악이 어우러진 종합예술로 인정받아 국가 및 각 시도 무형문화재로 지정받고, 예술대학 등에서 전공교육과정으로 편성되어 무속을 전공한 새로운 학습무들이 등장하게 되었다. 이들 학습무는 대학, 동해안별신굿보존회, 굿이 진행되는 현장 등에서 동해안별신굿의 연희 능력을 체계적으로 전승받고 있다. 시대의 변화에 따라 세습무가 학습무들을 받아들여 무업을 계승해나가며 굿의 연행 집단과 굿을 수용하는 마을 사람들의 인식에도 변화가 나타났다. 과거와 달리 굿이 한국전통예술의 원형으로 가무악 총체적 학습의 산물로 인정받으며 국가무형문화재로 지정을 받게 됨으로써 무당의 사회적 지위와 개인적 자존감이 매우 높아지게 되었다. 과거 천시 당하던 무당이 아닌 대내외적으로 인정받는 전통예술인으로 자리 잡게 되면서 굿 현장이나 마을사람들과의 관계에서도 그 지위나 대우가 많이 달라졌다. 마을 구성원들도 무집단의 세대가 변화함에 따라 과거와 달리 새로운 학습적인 요소들이 첨가된 것에 대해 인정하고 수용하는 입장을 취하고 있다. 마을단위에서도 전통적인 굿의 형식이나 제의만을 주장하기보다 마을 주민 모두가 함께 어우러질 수 있는 축제 형식이나 다양한 굿의 방향성을 고민하고 있다. 변화하는 굿의 흐름과 신진 세대의 적응에서 새로운 의미를 찾아나가고 있는 것이다. 급변하는 시대의 흐름에 따라 굿판이 점점 축소되는 현실 속에서 동해안굿은 다른 지역 굿에 비해 아직까지는 활발히 연행되고 있다. 힘겹게 동해안굿을 보존해 온 세습무의 뒤를 이어 학습무들이 활발히 유입되고, 연행 집단이 굿의 전통을 보존하는 한편, 굿을 예술 콘텐츠로 활용하기 위해 애쓰고 있기 때문이다. 또한 학습무들은 세습무로부터 배워 온 무속의 학습을 체계적으로 정리하여 후대에 최대한 원형에 가깝게 전승하고자 준비하고 노력하고 있다. 앞으로도 동해안굿은 마지막 세습무의 대를 이어 학습무들이 전통을 계승하고 시대에 맞춰 발전시켜 나갈 것이다.

The phytosocialogical study on the coastal sand dune vegetation of the East Coast was carried out. 180 phytosociological relev$\acute{e}$s of 62 sites in the East Coast were used in this study. In addition, already published syntaxa and the phytosociological hierarchy in Korea and Japan were used and comparative analyses of syntaxonomy, synecology, syngeography, and syndynamics were performed in the study. In this study, the flora was investigated 30 families, 66 genera, 77 taxa and 3 vegetation types were identified : the coastal drift-line annual communities (Calystegio soldanellae-Salsoletum komarovii), the dune glasslands communities (Elymo-Caricetum kobomugi, Carex kobomugi typical community, Elymus mollis community, Calystegia soldanella community, Zoysia macrostachya community, Cynodon dactylon community, Carex pumila community), and the dune shrubs communities (Linario-Viticetum rotundifoliae, Vitex rotundifolia community, Rosa rugosa community). The aspect of transition in the coastal sand dune vegetation of the East Coast were identified as follows : (1) reduced constancy degree and cover degree of Glehnia littoralis in each community; (2) lack of Ischaemum anthephoroides in Linario-Viticetum rotundifoliae (3) simplified species composition in Vitex rotundifolia community. Unstable habitat condition by external interference seemed to has caused the reduction of 2 taxa, Glehnia littoralis and Ischaemum anthephoroides, that usually grow in the second dune. In addition, we found changes in the distribution of the dune shrub communities influenced by rising temperature of the East Coast as results of the global warming. The results on the distribution of the dune shrub communities in this study demonstrated that the limit of the Rosa rugosa community made $0^{\circ}$ 44'N to the North and the vegetative limit of the Vitex rotundifolia community made $0^{\circ}$ 28'N to the North, respectively compared with the previously phytosociological studies. This study investigated the coastal sand dune vegetation, syntaxonomy, habitat condition and human disturbunce of the East Coast, and this will provide important information as basic data for the coastal ecosystem.

A merged altimeter data products are used to estimate sea level variation in the East Sea between 1993 and 2006. The altimeter data show a high correlation coefficient (0.85) after applying gaussian low pass filter for 180days at Ulleung island. The both of Mukho coast and Ulleung island are minimal sea level in March to May and maximal in September to November. Sea level of Mukho coast is higher than that of Ulleung island during March to May, while Mukho coast is lower during September to November because the North Korea Cold Current flows along the coast line of Mukho. Generally sea level variation at Mukho coast and Ulleung island associated with seasonal variations.

The sea hare Aplysia kurodai is an economic species located along the Korean coast. This study aimed to investigate the stomach contents of A. kurodai and its relationship with marine algal flora surrounding their habitat. A. kurodai and marine algae were sampled in seven and five areas in the East and the South seas, respectively. The marine algae found in the stomach and surrounding marine habitat were identified. In the East Sea of Korea, 134 species of seaweed were recorded. Thirty-nine species of marine algae were identified in the stomach contents of A. korudai collected from the East Sea of Korea. Seventy-five species of seaweed were collected in the South Sea of Korea. In addition, 26 species of marine algae were identified in the stomach contents of A. kurodai from the South Sea of Korea. Among the stomach contents of A. kurodai, ten sheet,12 filamentous, 27 coarsely branched, and one jointed calcareous form species were identified.

We made intensive observations on the coastal upwelling off the coast of the southern East Sea from June to August in 2001. The upwelling exhibited a weekly waxing and waning. The coastal upwelling of the year 2001 was characterized by abrupt outbreaks and the small local scale. Upwelling occurred more frequently off the coast of Ulsan and Gampo as reported by the earlier observers. The spread of freshly upwelled colder water was varied by each upwelling event. Generally cold waters were carried away northeastward off Pohang province. The upwelled cold waters were saltier than the resident surface waters. The pH and salinity-normalized alkalinity support the idea that the upwelled waters originate from the interior of the East Sea. The extraordinarily high concentration of dissolved oxygen suggests that the upwelled waters are closely connected to the southward flowing North Korea Cold Current. Although a lower primary productivity was reported for the upwelling region, underway surface fluorescence measurement revealed that the recently upwelled waters supported up to an order of magnitude higher algal biomass than the ambient waters. Because thermohaline circulation of the East Sea is so vigorous, with an estimated time scale of less than one hundred years, that the coastal upwelling should be considered not as an anomaly but as a regular component of a circulatory system. A quantitative understanding of upwelling seems to be a key to elucidate material cycling and the associated biological production in the East Sea.

본 연구에서는 동해안의 4개 정점(속초, 묵호, 후포, 진하)에서 13년간 관측된 파랑자료를 이용하여 극치확률분석을 통해 재현빈도별로 천해설계파를 산정하였고, 이 값을 한국해양연구원(2005)에 제시된 동해안 심해설계파를 이용하여 SWAN 수치모델링로 계산된 결과와 비교하였다. 그 결과 2005년 기존 심해설계파의 수치실험 결과는 관측파랑에 의한 극치분석 결과보다 상대적으로 작은 것으로 나타났으며, 특히 30년 빈도 이하에서 동해안에서의 기존 심해설계파고가 과소산정되었을 가능성이 있음을 시사한다.
