Some environmental parameters on the shell-fish farms in Deukryang and Gamagyang Bays during summer in 1981 were determined to find an eutrophication level for the conservation of the farm. Chlorophyll-a content in the seawater in the Deukryang Bay in September was $1.0{\sim}5.0{\mu}g/l$ with an average of $2.5{\mu}g/l$ In the superficial bottom muds, contents of COD were 5-10 mg/g, ignition loss $5-9\%$, phaeophytin pigment $2{\sim}5{\mu}g/g$, and sulfide 0.1-0.3 mg/g dry mud in both bays. High contents of both organic matters and sulfide were found in the innermost area of the Deukryang Bay and in the north western part of the Gamagyang Bay. All quantities including chlorphyll-a in the water are little less than or similar to those of Hansan-Geoje Bay, one of the most productive shellfish farms in the southern coastal waters in Korea . Eutrophication on both water and bottom mud was under way like other shellfish farms but pollution indices on the bottom mud calculated from the data of CODs and phaeophytin pigments shelved 6-11, which is much lower than those of Jinhae Bay and of the Hansan-Geoje Bay. This means that the bottom muds are in an early stage of eutrophication, unlike the Jinhae and Hansan-Geoje Bays though the water, similar to the other bays, shows a middle stage of eutrophication.

This study investigated the physicochemical and enzymatic properties of unmarketable bastard halibut (Paralichthys olivaceus) cultured in different regions (i.e., Jeju, Wando, and Geoje) as a potential source of surimi and surimi gel. The proximate composition of unmarketable bastard halibut cultured in different regions did not differ significantly at P<0.05. Compared to Alaska pollock muscle, all of the unmarketable bastard halibut muscle had a 4% higher crude protein content and 5% lower moisture content. The collagen content of bastard halibut muscle cultured in Jeju was 1.96 g/100 g, which was higher than in fish cultured in other regions. Regardless of the region where cultured or pH, the enzymatic activities of the crude extracts from unmarketable bastard halibut muscle ranged from 0.30.0.48 U/mg for casein and hemoglobin, 11.9.13.7 U/mg for LeuPNA, 5.6.6.7 U/mg for ArgPNA, 2.8.4.7 U/mg for SAAPFNA, and 0.1.0.2 U/mg for BAPNA. Regardless of region, no mercury or lead was found in any of the unmarketable bastard halibut muscle, except for lead in fish cultured in Geoje. The strength of surimi gels from unmarketable bastard halibut cultured in Jeju, Geoje, and Wando was 1059, 988, and 900 g${\times}$cm, respectively. The surimi gel from unmarketable bastard halibut cultured in Jeju was stronger than commercial Alaska pollock surimi, which was grade SA.

The aim of this study was to determine the characteristics of wave transformation in the shallow water of the Nakdong River estuary due to variations in air pressure, air temperature, wind speed, and wind direction. We analyzed the correlation between weather factors and wind waves in offshore regions near Geoje Island and the Nakdong River estuary in April and May 2007. The weather and wind wave data were obtained from the automatic ocean observation buoy near Geoje Island operated by the Korean Meteorological Administration (KMA). For the estuary region, the wind wave information was the result of field observations, and weather data were obtained from the Busan Meteorological Station. Field observations of water waves in April and May showed that the maximum wave height decreased by about 2.2 m. M oreover, wave height decreased significantly by about 1.3 m due to the reduction in wave energy caused by the water waves propagating from Geoje buoy to the Nakdong River estuary. We conclude that offshore or wind waves coming into the Nakdong River estuary showed considerable height variation due to the prevailing weather conditions, especially wind speed and direction. In particular, headwinds tended to decrease the wave size in inverse proportion to the wind speed.

This study was carried out to furnish basic information on the habitat through soil condition and vegetation structure of an Acer mono for. rubripes stand in Geoje, Gyeongnam Province. Soil pH of the A. mono for. rubripes stand was 5.17. The contents of organic matter, total N and available P205 were 8.7%,0.38%, 15.7ppm, respectively. A. mono for. rubripes, Meliosma oldhamii, Zelkova serrata, Styrax japonica, Sapium japonicum, Lindera erythrocarpa and Euonymus oxyphyllus appeared in all layers. The importance values of A. mono for. rubripes, Z. serrata and Quercus serrata in the upper layer were high, S. japonicum and M. myriantha were high in the middle layer and lower layer, respectively. Species diversity and evenness ranged from 0.931 of the middle layer to 1.638 of the lower layer, and from 0.706 of the upper layer to 0.959 of the lower layer, respectively. The study results provide basic information on soil condition and vegetation structure of the Acer mono for. rubripes stand native to Geoje, Korea.

In manufacturing of ships, problems to be solved are improvement of productivity and stabilization of quality due to the shortage of skilled workers. Working environment, in particular welding environment, is also to be improved. One solution among these problems is to rationalize and automate these working. This paper is focused on the welding automation technologies in shipbuilding industry. The features of shipbuilding in the aspect of automation are described, and the main welding robot systems to be developed by SRI are introduced in each working stages.

This research does by purpose that present safe navigation plan for ships during doing dredging construction with dredger crossing waterway of Gadeok Dredging operations need to build sunken tunnel that cross the bottom of the sea under waterway of Gadeok for access road construction between Busan- Geoje. Accordingly, dredger must cross and dredge waterway of Gadeok fatally. There is possibility of marine accident of collision for latent danger situation of ships to navigate waterway of Gadeok relatively. Therefore, safe navigation plan of ship is groped in reply and its countermeasure is presented. Firstly, navigating traffic in daytime was forecasted less than 20% of its maximum capacity through estimating the traffic volume and traffic congestion The proposal was presented to execute dredging operations in three-step and to establish temporary waterway after reviewing waterway design principles. The role of VTS center was emphasized in the new Busan Port, lastly.
