A study on the distribution and community structure of the benthic molluscan shells of the southern coastral area in Cheju Island was carried out from August 1990 to July 1991. The benthic molluscan shells collected and identified from 8 stations were composed of 3 classes, 7 orders, 22 families and 59 species. The number of appearance species from station 1 to station 8 were 22, 35, 32, 26, 28, 24, 32 and 31 species respectively. the first dominant species of the upper intertidal zone of the 8 stations were Nodilittorina exigua, those of the middle zones were Monodonta neritoides from st.1 to St.5, but the second dominant species were not uniftom at ach station.

In order to foster the minor enterprises effectively we will have to take a proper step to control and adjust the excessive competitions of large-enterprises and minor as well as among minor enterprises, We should promote the relationship serialized between minor - and large - enterprises and establish mediation and control organizations and governmental policies to create re-subcontract among small and medium enterprises. To help the development of medium md small enterprises in Jeon-Buk area, therefore, Kunsan city should be designated as a Growth Position City. The reason is as follows. 1) Because Kunsan is located in Middle Western Seaside geographycally, and in the central place of our country as a key point of sea-transportation, we can cultivate the national land widely. 2) As an ocean gateway city of Kum River basin, Kunsan is a good place that can reform Hoh-nam inland of Kwang-iu, Jeon-ju, I-ri, and like places as well as central inland area of Dae-jeon, Chong-ju, etc.. 3) Kunsan is an advanced-base for constituting an industrial region of Weatern roast that has a spacious coastral industrial region and is connected with inland industrial park of Jeon-ju and I-ri and Jang-hang, Bi-in, etc.. From the above reason. Kunsan should be designated as a growth position city that can induce and promote the development of center of Western coast.

Image data collected by an airborne hyperspectral camera system have a great usability in coastal line mapping, detection of facilities composed of specific materials, detailed land use analysis, change monitoring and so forh in a complex coastal area because the system provides almost complete spectral and spatial information for each image pixel of tens to hundreds of spectral bands. A few approaches after classifying by a few approaches based on SAM(Spectral Angle Mapper) supervised classification were applied for extracting optimal land cover information from hyperspectral images acquired by CASI-1500 airborne hyperspectral camera on the object of a coastal area which includes both land and sea water areas. We applied three different approaches, that is to say firstly the classification approach of combined land and sea areas, secondly the reclassification approach after decompostion of land and sea areas from classification result of combined land and sea areas, and thirdly the land area-only classification approach using atmospheric correction images and compared classification results and accuracies. Land cover classification was conducted respectively by selecting not only four band images with the same wavelength range as IKONOS, QuickBird, KOMPSAT and GeoEye satelllite images but also eight band images with the same wavelength range as WorldView-2 from 48 band hyperspectral images and then compared with the classification result conducted with all of 48 band images. As a result, the reclassification approach after decompostion of land and sea areas from classification result of combined land and sea areas is more effective than classification approach of combined land and sea areas. It is showed the bigger the number of bands, the higher accuracy and reliability in the reclassification approach referred above. The results of higher spectral resolution showed asphalt or concrete roads was able to be classified more accurately.
