Standard recipes of various fish dishes for cook/chill system were developed to provide foodservice managers in kindergarten with more effective management system. Three kinds of fish dishes, Broiled Mackerel, Flounder Stew and Squid Bulgogi were selected as menu items in this study, and the standard recipes for these fish dishes were developed through the sensory evaluation, and microbiological analyses were performed to assure the quality of fish dishes. The microbial counts of the fish dishes which were chilled at 0∼3$^{\circ}C$ and stored for 10 days in refrigerator were as follows : Aerobic bacteria were not detected in Broiled Mackerel; however, those in Flounder Stew were 2.92${\pm}$0.01∼3.84 ${\pm}$0.06 Log CFU/g and those in Squid Bulgogi were 3.16${\pm}$0.01∼4.80${\pm}$0.02 Log CFU/g. Coliform bacteria were not detected in any fish dishes. All the sensory characteristics showed no significant differences between the first and third day of storage, except the feeling after swallowing of Flounder Stew. Overall acceptability scores of chilled stored foods in the first and third day were 6.87${\pm}$0.99 and 6.40${\pm}$1.40 in Broiled Mackerel, 6.87${\pm}$0.35 and 6.73${\pm}$1.10 in Flounder Stew, 6.13${\pm}$0.99 and 6.07 ${\pm}$0.80 in Squid Bulgogi, respectively.

In this study, we investigated the effect of reaction factors on enzymatic hydrolysis of Hizikia fusiforme, which is brown algae in marine biomass resource, using commercial enzymes. The composition of H. fusiforme is 38.9% of reducing sugar, 4.8% of moisture, 17.8% of ash, and 38.5% of others. In the condition of 1-5% substrate, the increase of substrate concentration enhanced the increase of reducing sugar formation; however, the hydrolysis yield did not increase after 24 h. After reaction of 75 h, conversion yield of reducing sugar were obtained to 16.45%, 17.99%, and 14.55% at 1, 2.5, and 5% substrate, respectively. As a result of effect of enzyme amount, the formation of reducing sugar did not show considerable change at 1% substrate. However, in the condition of 2.5% substrate, the great change of reducing sugar formation was observed by the increase of enzyme amount. The conversion yields of reducing sugar were obtained to 18.77% and 22.83% at 1% and 2.5% substrate with 30% enzyme, respectively. As a result of heat treatment of biomass, the high yield was obtained in 2.5% substrate and the yields were increased to 0.06-7.2% by the heat treatment. This result will provide the basic information for production process of biofuels and chemicals from marine biomass H. fusiforme.

The objectives of this study are to build up the concept of Environment-Oriented Land Suitability Assessment(EOLSA) and to develop the EOLSA mapping system by applying the EOLSA criteria to the case study area. In order to draw out the EOLSA critera, this study adopted the Delphi method including the experts' awareness survey to urban planners as well as environmental researchers in May and June 2001. As a result, the concept of EPLSA was defined as a process of land use planning to scientifically assess the physical and environmental value of land and to classify conservation aptitude into several grades for the sustainable management of environmental resources. With an outcome of applying the EOLSA criteria with five degrees to the Seoul Metropolitan Area (SMA), Grade I, indicating the highest conservation value, accounted for 57.76% of the SMA. Then, Grade II reached up to 15.06%, Grade III 3.12%, Grade IV 15.92%, and Grade V, the lowest conservation value, 7.99% respectively. And also, the case analysis showed that the share of Grade I area was the highest in Gapyong county and Yangpyong county, Pochon county, Yeonchon county, Yongin city in the order and the lowest in Kwangmyong city, Osan city, Kunpo city, Kuri city, and Buchon city.
