This study aims to propose the future plan and research management of a beach and the relation between spatial structure of a village and layout of the beach focusing on Gimnyeong beach among the 12 general beaches in Jejudo. The results are as followings: First, Gimnyeong beach had the relation to primary industries of residents in the village in times past and was the space for everyday lives of residents. However, at present it has the relation to tertiary industries and is more important in community activities. Second, the entry part and the sandy beach of Gimnyeong beach were crucial in location and function in times past but total size of the beach has expanded for campground nowadays. Therefore, it is necessary to change the location of entry part to center part of the beach. In addition, convenient and safe facilities are need to be built more to corresponding to expanding area of the beach. Finally, in order to maintain clean sea, residents in the Gimnyeong have agreed to not make sea farms in the vicinity of Gimnyeong Beach which pollute the sea. Their roles have influenced on positive effect to community of the village, management of the beach, and maintenance of clean sea.

This study undertook to evaluate the quality characteristics of rice, to select a variety suitable for porridge. Seven varieties of rice were studied: Dabo, Daebo, Samkwang, Sindongjin, Sukwang, Jinsumi and Haiami were investigated for proximate contents and physicochemical characteristics. The moisture and crude protein contents of the rice cultivars were in the range 11.26-12.66% and 5.34-6.47%, respectively. The amylose content was the highest in the Samkwang (20.83%), and lowest in Haiami (18.32%). The water binding capacity and solubility of Samkwang and Jinsumi cultivars were greater than those of the other samples. Hardness of rice and viscosity of porridge was the least in Samkwang and Sukwang. The pH of porridge in Samkwang and Jinsumi (7.04) was higher than the other varieties (6.80-7.03). The results of this study indicate that Samkwang and Jinsumi are suitable varieties for porridge. We expect this data will be useful in the manufacturing of porridge.

Rice in Korea is a highly valuable food resource that serves both as staple food and ingredient in various processed edibles. This study was conducted to explore pre-treatment methods for rice that result in good saccharification upon production of rice beer. When rice was subjected to fine grinding, steeping, roasting, gelatinizing, or puffing prior to saccharification with malt, wort containing puffed rice had the highest soluble solid content (°Bx). Upon production of wort without the addition of any enzymes for liquefaction or saccharification, the addition of 30% rice resulted in the highest soluble solid content (°Bx). Production of beer containing 10, 20, or 30% of either roasted or puffed rice showed that wort containing 30% puffed rice had the highest soluble solid content (15.4 °Bx) with good saccharification. The resulting beer likewise exhibited higher alcohol content (5.0-5.4%) than the beer that had roasted rice added, without the turbidity and with less bitterness. Therefore, rice puffing was considered a beneficial processing method to enhance rice saccharification and to facilitate both the production of fine quality beers and rice beer containing puffed rice.

Abstract [] The prediction of changes in the tidal regime due to the sea dike closure in the Saemankum area was performed using the nonlinear finite element model, TIDE. Based upon an overall comparison of calibrated model results with available field data, the TIDE model behaves well and is good representation of the hydrodynamic of the Saemankum tidal project area. It is shown that the TIDE model does an excellent job of computing the changes of tidal characteristics resulting in sea dike closure in an estuary area.

Feeding behavior of Temora turbinata was investigated through laboratory experiments with special emphasis on its food preference and consequent clearance rate on diatom and microbial components given as common natural food assemblage of coastal area (Uchiumi, Uwa Sea, Japan). Among available prey items, T. turbinata showed the highest clearance rate for Thalassiosira spp. ($0.23{\pm}0.08L\;Temora^{-1}day^{-1}$) followed by Chaetoceros spp. ($0.11{\pm}0.03L\;Temora^{-1}day^{-1}$), but clearance rates for other diatom, Nitzschia spp. was lower (0.03 to $0.07L\;Temora^{-1}day^{-1}$). Bacterial abundances showed no response against 24-h feeding of T. turbinata. Feeding of T. turbinata on heterotrophic nanoflagellates (HNF) was apparent when clearance rates of T. turbinata on diatoms were relatively low, but T. turbinata did not consume HNF as well as ciliates with Thalassiosira spp. of which clearance rate was highest. The results suggest that HNF and ciliates are possible supplementary prey item for T. turbinata, but their contribution as food sources can be limited by the presence of other prey items such as preferable diatom species.

This study was examined the nutritional conditions of 250 students of middle school from March 5 to 8 in 1993, who are eating their lunch-box. This results were summarized as follows; The average height of the boy students is 156.9 cm. It is 98.6% of the standard height of middle school students. That of the girl students is 153.1 cm. It is 98.7% of the standard height of middle school students. The average weight of the boys is 49.3 kg (98.6% of the standard) and that of the girls is 45.9 kg (95.6% of the standard). The average weight of the staple of their lunch-box is 480 g (boys) and 349.5 g (girls). Among the subjects, 58.8% carry two side dishes, and they eat 36 kinds of side dishes, including kimchi usually cooked by roasting. The balanced diet based on the five basic food groups is almost impossible, especially they don't eat sufficiently protein food and calcium food. All the nutrients except Vitamin A, C and Niacin, are below the Recommended Daily Dietary Allowances for Koreans. The rate of calorie of carbohydrate: fat: protein is 80.5:8. 4:11.1 (boys) and 79.3:9.9:10.8 (girls). The 80% of total amount of calorie was from carbohydrate.

The objective of this study was to evaluate quality properties, including amylopectin content, and texture analysis of brown rice and germinated brown rice cultivars in Korea for rice processing products. The amylopectin short chain content of germinated brown rice was significantly higher than that of brown rice. Texture analysis test showed that germinated brown rice Jinbo had the lowest hardness and toughness as well as and highest stickiness and adhesiveness. The correlation between degree of polymerization of amylopectin and texture analysis was also evaluated. In particular, germinated brown rice, short-chain amylopectin showed a negative correlation with hardness and toughness, whereas long-chain amylopectin showed a positive correlation with hardness, toughness, and adhesiveness. These results indicate that there is a relationship between degree of polymerization and texture analysis.

Due to tidal force, it is very difficult to estimate the hydraulic parameters of high permeable aquifer near coastal area in Jeju Island. Therefore, to eliminate the impact of tidal force from groundwater level and estimate the hydraulic properties, tidal response technique has been mainly studied. In this study we have extracted 38 tidal constituents from groundwater level and harmonic constants including frequency, amplitude, and phase of each constituent using T_TIDE subroutine which is used to estimate oceanic tidal constituents, and then we have estimated hydraulic diffusivity associated with amplitude attenuation factor(that is the ratio of groundwater level amplitude to sea level amplitude for each tidal constituent) and phase lag(that is phase difference between groundwater level and sea level for each constituent). Also using harmonic constants for each constituent, we made the sinusoidal wave and then we constructed the synthesized wave which linearly combined sinusoidal wave. Finally, we could get residuals(net groundwater level) which was excluded most of tidal influences by eliminating synthesized wave from raw groundwater level. As a result of comparing statistics for synthesized level and net groundwater level, we found that the statistics for net groundwater level was more insignificant than those of synthesized wave. Moreover, in case of coastal aquifer which the impact of tidal force is even more than those of other environmental factors such as rainfall and groundwater yield, it is possible to predict groundwater level using synthesized wave and regression analysis of residuals.

Natural resource of the island and coastal regions is one of the most important element of ecological network system in Korea. Currently, there is trend that natural and biological resources such as fishing and tidal wetland have been used to local economic activation in island and coastal regions. According to the 5-days work in a week, island and coastal regions become important amenity resource of citizen's recreation area. Korea is peninsula surrounded by maritime. Especially, South and West Sea surrounded by many islands and tidal flat wetlands are emerging marine ecosystem and seascape in the world. Natural resource is limited, so we have to sustain those resource to current tourism. In this study, I would like to suggest that importance of cultural resource as well as natural resource for 'eco-cultural tourism' in order to keep both biological diversity and cultural diversity as amenity resource for future island economic activation in Korea.
