본 연구는 PC-cluster를 플랫폼으로 사용하는 호남지방 고해상도 기상예측시스템을 이용하여 기존에 광주의 고층자료만 사용했을 때와 흑산도의 고층자료를 추가하였을 때의 3차원 자료동화의 차이가 지리산을 중심으로 한 호남지방의 강수예측에 미치는 영향을 알아보고자 수치실험 결과와 호남지방의 관측결과를 통하여 모델을 통한 강수예측을 검증한 것이다. 광주와 흑산도의 자료로 강수예측 결과를 비교해 본 결과, 광주는 22일 12LST 이전부터 강수가 시작되었는데 광주의 고층자료만 사용한 EXP1에서는 강수가 나타나지 않는 반면에 흑산도가 추가된 EXP2에서는 강수예측이 향상된 것으로 나타났다. 따라서 흑산도의 고층 데이터가 추가된 3차원 자료동화가 광주 예측능력을 향상시킬 것으로 판단된다.

Aerological observation at Heuksando located in south-western part of Koran Peninsula has been started at 1 June 2003. In order to clarify the improvement of meteorological prediction quality. it is necessary to compare between aerological data observed at Gawngju and Heuksando and to make clear the influence of Heuksando data assimilation. Therefore numerical simulations were carried out with High resolution meterological prediction system based on MM5(The 5th Generation Mesoscale Model). The pattern of wind and temperature field observed at Heuksando and Gwangju are different due to land surface friction End Sensible heat flux at surface and the wind field Simulated With Gwangju and Heuksando aerological data agree well with observation wind field. Although the amount of precipitation in these experiments is underestimated. the area and starting time of precipitation around Honam province in case with Heuksando data is more reliable that without the data.

다산 정약용은 공직자가 지켜야할 "목민심서"를 쓴 유명한 실학의 대학자이다. 그는 우리나라에 우두를 처음 도입한 인물의 하나로 근대과학과 관련된 글을 남겼다. 그리고 그보다 4살 위인 형 정약전도 이름난 과학자였다. 형인 정약전은 한국과학바사의 고전으로 볼 수 있는 "자산어보"를 쓴 사람으로 흑산도의 물고기에 대한 조사보고서를 담은 책이다. 이들 형제는 전남 강진과 흑산도로 유배되어 유배지에서 학문탐구에 불태운 형제 과학자이다.

Hwangheuk-san (HHS) is a Korean multi-herb formula comprising four medicinal herbs. HHS, which was recorded in “Dongeuibogam,” has been used to treat patients with inflammation syndromes and digestive tract cancer for hundreds of years. However, little is known about its anti-tumor efficacy. The present study investigated the pro-apoptotic effect and mode of action of HHS against AGS human gastric carcinoma cells. HHS inhibited the cell growth of AGS cells in a dose-dependent manner, which was associated with the induction of apoptotic cell death, as evidenced by the formation of apoptotic bodies, chromatin condensation, and an accumulation of cells in the sub-G1 phase. HHS-induced apoptotic cell death was associated with the up-regulation of pro-apoptotic Bax protein expression, down-regulation of antiapoptotic Bcl-2 protein, and the release of cytochrome c from mitochondria to the cytosol. The treatment of AGS cells with HHS significantly elevated the generation of reactive oxygen species (ROS). Additionally, apoptosis-inducing concentrations of HHS induced the activation of both caspase-9 and -8, initiator caspases of the mitochondrial-mediated intrinsic and death receptor-mediated extrinsic pathways, respectively, and caspase-3, accompanied by proteolytic degradation of poly (ADP-ribose)-polymerase. However, ROS scavenger and pan-caspases inhibitor significantly blocked HHS-induced growth inhibition and apoptosis. Taken together, these findings suggest that HHS induces apoptosis through ROS- and caspase-dependent mechanisms and that HHS may be a potential chemotherapeutic agent for the control of human gastric cancer.

Hongdo and Huksando belong to the Dadohae national park parks in Korea and are famous sightseeing spots in Shinahn-gun. One of the keystone species in this area is otter (Lutra lutra). We accomplished field works for finding its present habitat and condition analyses for the potential habitat in the area via spatial analyses with digital elevation model and satellite imagery. Isolated condition with coastal cliffs was one of the superior conditions over habitat in the main land, but the road kills of small animals were also observed. Three underground eco-corridors were suggested for the protection of otter habitat in the Shinahn-gun area. Regional development strategies of Shinahn-gun should be focused on the protection of safe and pristine habitat for otter population.

We report an Early Cretaceous zircon U-Pb age ($113.9{\pm}1.2Ma$) for the Heuksan-do granite located about 90km from Mokpo offcoast of the southwestern Korean peninsula. At this Aptian/Albian boundary, widespread igneous activities occurred not only in the Korean peninsula but also in the eastern China and Japan. We raise the possibility that the flat-slab subduction and delamination triggered such an episodic igneous activity over the large areas of East Asia.

In this study, the general compositions, amino acids, fatty acids and collagen content of three abalones, which were harvested in Wando, Heuksando and Jeju Island in Korea, were analyzed and compared. The abalone body and viscera were separated from each other and the physicochemical properties were investigated. The moisture and protein contents of the viscera were lower than that of the body; while the lipid, carbohydrate, and mineral contents were higher. The general compositions and mineral contents also presented fluctuation among the three abalone groups. The amino acid content via hydrolysis in the abalone viscera ranged from 93.16 to 127.02 mg/g, which was lower than the amino acid content of the abalone body of approximately 145 mg/g. However, the free amino acids level in the abalone viscera ranged from 16.81 to 20.10 mg/g, which was higher than that of the abalone body level of approximately 7.90 to 10.59 mg/g. The fatty acid analysis revealed that while the saturated fatty acid percentages in the abalone body were higher than in the abalone viscera, the percentages of the monoenoic and polyenoic fatty acids of the body were significantly lower. The body of the abalone harvested in Wando contained the highest level of collagen ($2.26{\pm}0.46mg/g$), followed by the abalone harvested in Jeju Island and Heuksando. The abalone viscera contained much lower collagen, which ranged from $0.37{\pm}0.15mg/g$ to $0.20{\pm}0.03mg/g$. The results of this study will provide useful information for the future research of abalone.
