The medicinal plants in 22 unhabited islands of Jindo-gun, Chonnam provincde were investigated from March 2000 to October 2002. The medicinal plants in 22 uninhabited islands of Jindo-gun were consisted 366 taxa; 95 families, 269 genus, 309 species, 52 varieties, 3 forma, and 2 subspecies. Important medicinal plants on survey area were Lemmaphyllum microphyllum, Dendropanax morbifera, Ficus erecta, Farfugium japonicum, Machilus thunbergii, Juniperus chinensis var. procumbens, Dendrobium moniliforme, Pyrrhosia tricuspis, Cinnamomum japonicum, Pittosporum tobira, Kadsura japonica, and Daphniphyllum macropodum, This result can be used as basic information data for medicinal research and the conservation of uninhabited islands.

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.

서남해안 부근의 섬에서 재배되고 있는 재래종 검정콩 유전자원 45품종(135점)의 조단백, 지방산 조성을 분석한 결과 조단백 함량 변이는 34.70-44.20%(평균 40.75%),지방산 조성 변이는 palmitic acid에서 9.00-14.40%(평균 11.41%) stearic acid에서 2.90-5.00%(평균 3.93%), oleic acid에서 22.25-26.50%(평균 22.75%), linoleic acid에서 50.30-57.20% (평균 53.55%), linolenic acid에서 6.70-11.20%(평균 8.35%)의 변이를 보였다. 지방산에 대한 유전력은 oleic acid에서는 높았으나 stearic acid와 linolenic acid에서는 낮았으며 palmitic acid, linoleic acid는 조단백의 유전력과 같은 경향으로 중정도 이었다. 형질상호간의 상관 계수에서 조단백은 oleic acid와는 고도의 유의차로 정의 상관을, linoleic acid와는 고도의 유의 차로 부의 상관을 보였고 기타의 지방산간에는 부의 상관을 보였다.

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

Characteristics and variations of chemical compositions in Co-rich crusts occurred in the EEZ of the Republic of Marshall Islands were reviewed. Correlation coefficient analysis, hierarchical cluster analysis, and Q-mode factor analysis for 62 samples were done in this study. All data were selected and gathered from the open file report of the cooperative cruise done by United States Geological Survey with Scripps Institute of Oceanography, University of Hawaii or Korea Ocean Research Development Institute. The average of crust thickness. Co content, and Ni content of 62 samples from the 21 seamounts were 30mm, 0.58 wt% and 0.40%, respectively. The mineral phases and associated elements assigned by correlation coefficients, cluster analysis and Q-mode factor analysis are following four. 1) CFA: P, Ca, CO2, Y, Sr: 2) Mn-oxide mineral: As, Mn, Co, Na: 3) Al-silicate mineral: Pd,Si, Al, Cu, Fe: 4) PGE-bearing mineral: Rh, Pt, Ir.
