1420년대 강원도 관아는 일본과의 접촉이 거의 없었고，그때까 지 왜구들과의 접촉은 평화적인 교역으로 이루어지고 있었다. 이러한 일본인과의 교류방식 변화는 조선전기 강원도의 우산도와 울릉도 섬에 대한 정책으로 조선조정에게 알려졌다. 그리고 경상도 의 제포，부산포，그리고 염포 3개의 항구에서 접촉이 주로 이루어진 교역은 수군영의 보호된 지역에서 일본과의 교역통로로 집중되었다. 조선조정은 경상도 삼포에서 성공적으로 일본인 교역을 허용하는 정책을 수행함에 따라 모든 강원도 지역을 일본인들의 출현을 금지하였다. 강원도 지역에는 일본인들이 문인을 가지고 도항할 곳이 없었다. 즉 조선조정은 일본 배가 부적절한 방식으로 해안 수역에 나타나지 못하도록 제한하였다. 강원도 해안에는 섬이 적은 관계로 일본인들이 강원도로 내왕하기 어려웠다. 조선시대 우산도와 울릉도 역사는 일본인 접촉과 교류로 연관되어 있었다.

This study has found out the status of the environment ecology(topography structure. land-use, flora, plant community structure, wildbird) in 10 uninhabited islands(i.e. Kei island, Hadon island, Sangdon island, Daewa island, Hwanggang island, Naebi island, Oebi island, Prickly castor-oil tree island, Tongin island, Yuk island), Namhae-gun, Gyeongsangnam-do. Moreover, It has suggested ways of improving the environment ecology status by classifying the type of environment ecology about the degree of use and damage that based on the results of environment ecology survey. According to the results of topography structure survey, the survey site altitude was ranged within 1m~25m, otherwise, the radient was classified the rock area(.i.e. slope of less than 5˚ the dead level) and the slope area where is steep slope. Moreover, there was showed evenly a variety of aspect. Land-use were divided the field(Kei island), dry native grasslands(Hadon island), naturalized grasslands(Sangdon island), Pinus thunbergii community(Dacwa island, Hwanggang island, Naebi island, Yuk island), the rock area(Oebi island, Prickly castor-oil tree island, Tongin island). As the results of flora survey, the number of plant species were 30~115 species and the naturalized species were found 2~12 species in each site. The results of plant community structure analysis, The dominant species were Pinus thunbergii and Pinus densiflora were in upper tree layer, furthermore, it were Pinus thunbergii, Eurya japonica, Prunus sargentii, Celtis sinensis, Morus bombycis, ect. in cannopy tree layer. In shrub layer, the dominant species were Rosa multiflora, Rubus crataegifolius, Parthenocissus tricuspidata, etc. The status of wildbird bird, had been found 42 species 938 individuals, especially, there were Bubo bubo kiautschensis(natural monument No. 324) and Haematopus ostralegus osculans(natural monument No. 326). According to these synthetic results, we are able to classify the 5 types of environment ecology such as the natural coast forest that composed of Pinus thunbergii and Pinus densiflora(Daewa island, Hwanggang island, Naebi island, Oebi island, Tongin island, Yuk island), the field in vegetation area(Kei island), vegetation succession area of fallow field type(Hadon island), vegetation damage area by the forest fire and disturbance elements(Prickly castor-oil tree island), dominant naturalized species grassland by grazing cattle(Sangdon island).

In order to elucidate the polycyclic aromatic hydrocarbon concentration and its origin in arctic area, four arctic brown algae (Laminaria saccharina, L. digita, Alaria esculenta, Desmarestia aculeata), one marine invertebrate (Echinoidea) and sediments were collected from Kongsfjorden in Spitsbergen from the late July to early August, 2003. In case of macroalgae, the young blade part above growth point and the old stipes and blades beneath growth point were separated and analyzed for polycyclic aromatic hydrocarbons (PAHs) in an attempt to check the mechanism of uptake in macroalgae to accumulate PAH. There was no difference in PAH concentrations between sampling sites (Stations B and C), species, and blades beneath and above growth point. PAH concentrations in all samples collected in this study were relatively higher than those reported in other areas of arctic. Especially, station C, which is known as an unpolluted area, showed 10 times higher PAH concentration (8,765 ng/g) in sediment than station A (694 ng/g) around harbor. In addition high PAH concentration, station C had very higher proportion of methylated PAH to parent PAH in sediment than station A. Source analysis using PAH isomer pair ratios as indicators showed that Kongsfjorden area seemed to be relatively contaminated with PAH derived from direct petroleum input.

우리나라 남부 도서지역인 진도 지방에서 울금 다수확의 기 초 자료를 얻고자 차광 재배를 실시 한 결과는 다음과 같다. 진도 지역에서 울금을 4월 20일 정식할 경우 4주 지난 후에 출현되고, 출현율은 83­88%이었다. 초장은 129cm­147cm이였고, 차광의 정도가 높을수록 초장이 커지는 경향이었다. 엽장은 47.5cm­49.4cm로 차광 30­60%에서 약간 양호하였다. 또한 엽폭은 16.9­17.9cm로 차광이 높을수록 짧아지는 경향이었으나 유의성은 인정되지 않았다. 울금의 1주 근경중은 941­993g으로 비대가 잘되었고, 10a당 3,980­4,200kg을 생산 할 수 있었으며, 15%와 30%차광이 수량이 약간 증수되었으나 45%이상의 차광에서는 오히려 감소되는 경향으로 차광의 효과는 인정되지 않았다. 이러한 결과로 보아 울금을 재배할 경우 15%차광에서 생육이 가장 양호한 것으로 나타나고, 근경 수량이 약간 증수되나 경제성을 고려하여 재배하여야 할 것으로 생각된다.

The 129 soybean genotypes were collected in 43 island locations from January to May 2001. Seeds of 129 genotypes collected were analyzed for crude protein and fatty acid composition contents. The crude protein content was averaged to 41.1 % and ranged from 37.4% to 44.4%. The average palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid content were 12.0%, 4.0%, 23.2%, 55.5%, and 7.9%, and the ranges of those were 10.0% to 15.0%, 3.0% to 4.8%, 21.7% to 25.5%, 50.2% to 58.3% and 7.0% to 12.0%, respectively. Heritabiliries of palmitic acid, oleic acid, linoleic acid, and crude protein were higher, but that of stearic acid and linolenic acid were relatively lower. The genotypic correlation coefficients between crude protein and oleic acid showed highly positive correlation, but that of linoleic acid showed highly opsitive correlation, but that of linoleic acid showed highly negative correlation and also palmitic acid, stearic acid and linolenic acid showed negative correlation.

Mineral composition and chemistry of the clay minerals in the three cores from the continental shelves of South Shetland Islands (NCS09) and Anberse Island (GC98-2), and from the fjord of King George Island (A10-01) were determined by X-ray diffraction and electron microprobe analysis in search of the distributions and origin of the clay minerals in the Antarctic marine sediments. Smectite content is relatively high in NCS09 regardless of core depths (av. 8.3%), but low in GC98-2 (1.1%). In Al0-01, smectite content is higher in the upper section than in the lower section. Kaolinite was not detected from all the cores in this study Yellow to yellowish green clay granules were commonly scattered in the sediments of NCS09 cores. The clays contain 16.97% and 2.53% Fe2O3와 K2O. Average structural formula of the clay indicates ferrian beidellite . The (Fe, K)-rich smectite of NSC09 must have been derived from relatively young basaltic volcanics altered by reaction with seawater near Shetland Islands by glacial erosion or eolian process related to volcanic eruption. GC98-2 nearer to Antarctic continent is very low in smectite content. In A10-01, the lower diamicton was deposited from the glacial erosion of smectite-free ancient volcanics in the interior of King George Island, while the upper section was derived from the smectite-bearing terrestrial debris and eolian materials after retreat of glaciers in Marian Cove
