Saemangeum lake is an artificial lake created by reclamation works and an estuary embankment since 2006. The sea water flows into the lake by the operation of two sluice gates, and the freshwater enters into the lake by the upper streams. For the reflection of hydrology and hydrodynamics effects in Saemangeum area, a hydrodynamics model was developed by connecting Hydrological Simulation Program with Fortran (HSPF) and Environmental Fluid Dynamic Code (EFDC). The HSPF was applied to simulate the freshwater discharge from the upper steam watershed, and the EFDC was performed to compute water flow, water temperature, and salinity based on time series from 2008 to 2009. The calibration and validation are performed to analyze horizontal and vertical gradients. The horizontal trend of model simulation results is reflected in the trend of observed data tolerably. The vertical trend is conducted an analysis of seasonal comparisons because of the limitation of vertically observed data. Water temperature reflects on the seasonal changes. Salinity has an effect on the near river input spots. The impact area of salinity is depending on the sea water distribution by gate operation, mainly.

This study was carried out to compare the antioxidant components and antioxidant activity of brown rice according to addition rate (0, 10, 20, 30, 50, and 100%) and cooker. Brown rice was cooked using general and high pressure cookers with and without fermented alcohol. Pasting characteristics with addition rate of brown rice decreased with increasing amounts of brown rice. Total polyphenol and flavonoid contents increased with increasing amounts of brown rice. DPPH and ABTS radical scavenging activities increased with increasing amounts of brown rice. Moreover, brown rice cooked by the general cooking method with fermented alcohol showed higher antioxidant effects compared to other cooking methods. In this study, antioxidant components and antioxidant activity of cooking brown rice with addition rate and cooking method can be used as basic data on processed manufactured products.

The purpose of this study was to evaluate the effects of rice cultivars (Hangaru, Seolgaeng, Dasan-1 and Anda) on quality characteristics of rice beer. As for moisture content, Hangaru and Seolgaeng that are soft rice were higher than Dasan-1 and Anda as 14.48 and 14.62%, respectively. Dasan-1 and Anda showed higher protein content as compared to other varieties. As for amylose content, Hangaru turned out to be lower than other varieties as 17.71%, whereas reducing sugar content of Hangaru and Seolgaeng was higher than Dasan-1 and Anda. Results of hardness showed that Hangaru and Seolgaeng were measured lower than Dasan-1 and Anda. As a result of measuring alcohol content, pH and color of beer brewed by rice cultivars, no significant difference by cultivars was found, but measurement result of bitterness showed that beer brewed with Hangaru and Seolgaeng showed lower bitterness comparing to the beer brewed with Dasan-1 and Anda. The results of this study suggest that Hangaru and Seolgaeng are considered cultivars suitable for brewing quality of rice beer.

Lake Sihwa has a very unique watershed environment, surrounded by industrial, urban and rural catchment area with different land use. The first flush phenomenon was investigated in 3 catchment area. 4TG, representing the industrial area, shows rapid discharges of highly concentrated pollutants during the early stages of a storm and it is indicating a strong first flush effect. At AS, representing the urban area, the pollutant concentration reached its peak approximately 2~3 hours after the start of storm, which is a strong first flush effect did not appear. JJB and MS represent the rural areas, the PEMC analysis results suggest that highly concentrated pollutants were discharged during the middle and latter stages of a storm, instead of early pollutant runoff due to the effects of rainwater runoff.

As basic research for optimal barley cultivars selection and technical development for quality maintenance, a total of 21 commercial malt products (for making 'Sikhye', a traditional Korean sweet drink) were collected from the Korean market. And then we analyzed the component of the barley malt products as well as conducted comparative analysis on enzyme activity and quality characteristics of the commercial barley malt products. Of the 21 barley malt products, 12 were made from 100 % barley. The result of analyzing general components of barley malts turned out different level of components; moisture 4.91~11.99%, lipid 1.71~2.48%, protein 7.80~11.97%, carbohydrate 73.64~82.24%, total starch 5.50~8.22%, reducing sugar 3.64~14.44%. As a result of measuring enzyme activity of barley malts, there was a wide range of activity difference by the product; diastatic power $36.80{\sim}94.30^{\circ}$, ${\alpha}$-amylase activity 18.17~186.50 unit/g, ${\beta}$-amylase activity 6.53~25.05 unit/g. The results of this study would be used as basic data for optimal cultivars selection to produce barley malts and technical development for quality maintenance.

본 연구에서는 취반방법이 발아현미밥의 산화방지활성에 미치는 영향을 살펴보기 위해 발아현미 첨가비율별(0, 10, 20, 30, 50 및 100%)로 제조한 발아현미밥의 기능성분 및 라디칼 소거 활성을 살펴보았다. 호화특성은 발아현미 비율이 증가할수록 최고점도, 최저점도, 강하점도, 최종점도, 치반점도가 감소하는 경향을 보였다. 경도는 발아현미의 경우 일반 밥솥으로 취반했을 때 $20.54{\pm}0.79-20.03{\pm}0.77$로 나타났으며, 압력밥솥은 $9.76{\pm}0.26-9.27{\pm}0.43$으로 나타나 유의적으로 감소하였다. 총 폴리페놀 함량은 발아현미 첨가비율이 10, 20, 30, 50 및 100%로 증가할수록 백미를 기준으로 1.18, 1.39, 1.56, 1.90 및 2.91배 증자하였다. 또한 같은 발아현미 비율일 때 10% 발효알코올을 첨가하여 일반밥솥으로 취반하였을 때 높은 함량을 나타내었다. 이와 같은 결과는 총 플라보노이드 함량과 DPPH radical 및 ABTS radical 소거활성에서도 같은 경향을 나타내었다. 본 연구결과, 취반 시 발효알코올의 첨가와 압력밥솥으로 조리하였을 때 경도의 유의적인 감소를 확인할 수 있었으나, 페놀성분과 radical 소거활성의 증가는 발효 알코올의 첨가와 일반 밥솥으로 취반하였을 때 더 높은 값을 나타내었다. 이와 같은 결과는 취반방법에 따른 현미밥의 생리활성 연구에 기초자료가 될 것으로 생각된다.

The traditional farm houses in Yongdong area of Kangwon province have a different spatial structure from those of the other areas because of the characteristics of the climatic, geographic and sociocultural circumstances between the Taebaek mountains and the East Sea. So the purpose of this study is aimed at grasping how the spatial features of traditional farm houses in Yongdong area have been different in each regional circle. The plans of traditional farm houses of this region which are four types - ㅡ typed house without floor, ㅡ typed house with floor, ㄱ typed house without floor, ㄱ typed house with floor - show very similar but different space arrangements.

This study intended to compare rural development programs between China and Thailand, focused on research and extension activities. In China, Agricultural Science Administration(ASC) took charges in agricultural research, and under the ASC there were 39 agricultural organizations throughout the country. There were distinctive differences as to condition of agricultural areas, under-developed area at middle and developing area by sea and river. To improve agricultural production in China, diffusion of new agricultural technology would be important along with supplying equipment such as soil test kits, plant nutrition analysis sets and vehcles for extension educators. In Thailand, under the Ministry of Agriculture & Cooperatives, there were five departments, seven divisions and eight national enterprises. Among them, Department of Agriculture was in charge of agricultural research while the Department of Agricultural Extension for extension services. Each department had sub-division and provincial organization including personnel management and budget. However, the relationships and consistency between the Department of Agriculture and the Department of Agricultural Extension needed to be improved for better cooperation of research and extension.

Temporal and horizontal distributions of surface ozone concentrations covering the Busan metropolitan area were simulated by UAM -V (The Variable grid Urban Airshed Model) that was run with meteorological inputs taken from MM5 for ozone episode day (18 July 1999). UAM-V underestimated the daily maximum ozone con-centration about 14 ppb on average at all monitoring sites within Busan area comparing with observed value. but the correlation between observed and simulated values showed quite significant (R = 0.896, p< 0.01 on average). Higher concentrations of ozone occurred near the city center and industrial areas (western side of city) with high levels of anthropogenic source in the morning, and transport of ozone and its precursors by sea breeze developed in the afternoon contributed to elevated ozone levels in downwind rural areas. Particalarly in slightly downwind area of city center, the highest daily maximum ozone concentration ($\geq$120 ppb) was simulated by UAM-V at 1400 LST. Consequently, local environments including emission distributions and land -sea breeze circulation influenced ozone distributions in the Busan metropolitan area.
