1992년 10월부터 1993년 8월에 걸쳐 경기도 강화도와 인천직할시 영종도 2개 섬에서 털진드기에 관한 조사를 실시하였다. 포획한 42마리의 들쥐로부터 1,290개체의 털진드기를 채집하여 4속 8종을 동정하였다. 강화도에서는 전 계절을 통하여 Leptotrombidium pallidum이 93.0%를 차지하여 우점종으로 나타났으며, 영종도에서는 L. palpale가 38.4%를 차지하여 우점종이었고, L. pallidum은 한 마리도 채집되지 않았다.

Through ten field surveys in Kanghwa Island from August of 1997 to March of 2002, total 107 specimens of wood-rotting fungi belonging to the Aphyllophorales were collected and identified to the species. They taxonomically amounted to 10 families, 31 genera, and 48 species. Among them, one family, Steccherinaceae, and four genera, Australohydnum, Castanoporus, Dacryobolus and Haplotrichum were confirmed as new to Korea. Five unrecorded species, Australohydnum dregeanum, Castanoporus castaneus, Dacryobolus karstenii, Haplotrichum conspersum and Hyphoderma odontiiforme were registered here with descriptions.

강화 남단 갯벌은 우리나라 서해안의 가장 규모가 큰 갯벌 중의 하나이다. 조석은 전형적인 반일주조로 최대조차가 약 10m 이다. 강화 남단 갯벌은 한강 수계로부터 많은 양의 퇴적물이 유입된다. 연구지역에서 2003년 8월에 83개 정점에서 표층퇴적물을 채취하여 분석하였다. 표층퇴적물은 5개의 퇴적상으로 구성 되어 있었다. 일반적으로 모래 펄 퇴적물은 강화 남단 갯벌에서 우세하였고, 반면에 모래 퇴적물은 강화도 서부의 수로와 조하대에서 우세하였다. 이 지역의 1997년 8월 퇴적상과 비교하여 모래 펄 퇴적물은 갯벌의 동쪽으로 확장 되었다. 강화도 남단 갯벌에서 채취한 3점의 주상 시료에 대한 퇴적학적 분석 결과, 사층리 모래층, 실트-점토 호층 엽리 실트, 생물교란 실트등 세 개의 퇴적상이 인지되었다. 이들 퇴적상의 분포는 조수로 인근 지역이 전반적으로 퇴적률이 높으며, 특히 동검도 동쪽 갯벌에서 최근 급격한 퇴적 작용이 진행되고 있음을 지시하고 있다. 수리학적 관측을 위하여 2003년 6월에 염하수로의 초지대교 부근(K1)과 동검도 남부 수로(K2)에서 12시간 30분 동안 정선 관측을 실시하였다. 잔여유속 계산 결과 이 지역은 썰물이 강하게 나타났다. 각 수층의 부유물질 양에 의하여 계산된 순 부유퇴적물 이동양은 한 조석 주기 동안 염하수로에서는 외해로 309,217.9kg/m가 유출 되며, 동검도 남부 수로에서는 외해로 128,123.1kg/m가 유출 되는 것으로 나타났다. 동검도 남부 수로에 비하여 염하수로의 순 부유퇴적물 이동양이 높은 것은 갯벌의 동부에 한강에서 유입된 많은 부유물질이 퇴적된다는 것을 나타낸다.

The southern tidal flat of Kanghwa Island with an area of approximately $90km^2$ is one of the biggest flats on the west coast of Korea. Surface sediments for sedimentary analyses were sampled at 83 stations in August 1997, September 1999 and August 2000. The very poorly-sorted mud sediments were predominant in the eastern part of the tidal flat, whereas the poorly-sorted sand-mud mixed sediments were dominant in the western part. The area of muddy sediment distribution diminished, but that of sandy mud sediment extended to southeastward tidal flat for three years. In the western part of tidal flat, deposition occurred during the period of spring to summer, whereas erosion occurred in winter. Sediment accumulation rates during three years indicated that the sediments deposited continuously in the eastern part of tidal flat, whereas eroded in the western part of tidal flat. Recently, construction of artificial structures such as new airport, island-connecting bridges and dikes near the tidal flat might change tidal current and river flow pattern. In order to reduce the ecological damage and to preserve tidal-flat environment, it is necessary to Investigate long-term impacts on sedimentary environment and ecology.

In this study we classified sediment types of tidal flat using Landsat-5 images. This is for groping the method which can analyze correctly various kinds of sediment faces through satellite images. This work was performed by referencing ground truth of sediment faces which was investigated in the field. With this data we classified Landsat-5 image of 1997's to grope a most suitable classification method. As a result, in case of south Kanghwa island area, it was the optimum way to compound band 4, 5, 7 of Landsat-5 TM imagery. And, this work classified 3 kinds of sediment faces - M(mud), sM(sandy mud) and (g)M(slightly gravelly mud) - in land and mixed water area. It is anticipated that if this method is applied to a image of extremely lower sea level time, it can classify the sediment types of a broad tidal flat area. This is expected to be a beginning of estimating the effect of sediment faces to the change of the tidal flat ecosystem.

본 연구는 현재 강화도 남단 조간대의 마도요류(알락꼬리마도요 Numenius madagascariensis와 마도요 Numenius arquata) 서식지로서의 질을 평가하고자 환경수용능력(Carrying capacity)을 추정하였다. 저서무척추동물(칠게 Macrophthalmus japonicus)의 생물량 추산에 있어 토양 입도(Sediment grain size)의 공간 분포를 고려하였으며, GIS의 공간 분석 기법을 이용하였다. 추정 결과 2012년 봄철은 약 153일 동안 11,767개체가 이용할 수 있는 수준이었으며, 가을철은 약 122일 동안 16,275개체가 이용할 수 있는 수준이었다. 환경수용능력 대비 평균 도래 개체군의 차지 비율은 봄철 9.4%, 가을철 5.9%의 수준이었으며, 이는 분석 방법이 달라 직접 비교는 어려우나 1993-94년 선행 연구 대비 2.8-6.3% 수준이 감소한 수치였다. 과거에 비해 환경 수용 능력이 감소한 현재의 상황에서 향후 서식지 보전을 위한 지속적인 연구와 관리가 매우 시급하다고 판단되며, 나아가 향후 조간대의 다양한 서식지 특성을 반영한 공간 분석을 통해 더욱 정교한 예측이 필요하다.

A survey was conducted on the vegetation of Seogmo island, which is small island (ca. 41 okm2) located about 1km west of Kanghwa island in the central Korea, from Aug. 1983 to May 1984. Based on the field data, actual vegetation map and potential natural vegetation map were made. The island is covered with broad-leaved trees dominated with Quercus variabilis. The dominance diversity curves obtaiend in different associations are grouped in two types, lognormal distribution forms at the undisturbed vegetation and geometric series at the disturbed or rocky sites. It seems that the curves show to us the nature of their ecocline by the hypothesis of some investigators, i.e. Random niche boundary hypothesis, niche preemption hypothesis, lognormal distribution and logarithmic series. Total numbers of vascular plant species of the island were recorded 108 families, 348 genera, 475 species, 73 variaties and 7 forma. And Pte.-Q Index, 0.93, and Fisher's Index, 589.8, were higher than those in neighboring islands.

In order to understand the wintertime intermittent characteristics of the trans-boundary air pollutant transport observed in East Asia, a numerical simulation of the long-range transport of pollutants was applied using an atmospheric transport model(STEM-II). The numerical simulation was carried out for the entire month of January 1997 and specific atmospheric aerosol (including sulfate, nitrate, and other ion compounds0 observation data were compared from four observation sites(Cheju Island, Kanghwa Island, Dazaifu, and Fukue Island). The observation data revealed that concentration peaks were intermittently observed at 3 to 4-day intervals plus the four observation sites exhibited a very similar spatial variation. The horizontal and spatial scale of the heavily polluted air masses was analyzed based on numerical results. The mechanism of the intermittent transport of air pollutants was clearly explained by a comparison of the observed data with the numerical output. It was found that the wind pattern variations associated with the synoptic scale pressure system changes play an extremely important role in the transport of pollutants in this region.

The survey was carried out to obtain some fundmental data to improve the dietary life and to establish the nutritonal education and policy on inhabitants limed in isle area near by demilitarized zone in Korea. For this, 33 families in the area of Kyodong island located at Kanghwa-Gun, Kyungki province were randomly selected. Trained surveyors visited each house to survey the food and nutritional status in summer during 3 days in August, 1987. The results are summarized as follows ; The number of foods they were taking totalled 17 categories and 134 kinds of which 104 kinds were vegetable foods. The average amount of food intake was 1465.3g per person per day, animal food occupied 9.6% only. The intake amount of fruit among vegetable foods, and fishes, shells, milk and eggs among animal foods was lower than the national average. Each proportion of carbohydrates fat and protein to the total energy intake was 70.4%, 9.7% and 19.9%. The foods they used to take a lot were rice, potatoes. cucumbers, cabbage KIMCHIE and YULMOO KIMCHIE in order of their intake amount. The energy intake was 3064 Kcal which is higher than nutritional requirements, and the energy ratio of cereals to the total energy in take is 76%. If the amount of fat intake is fixed to 20% of total energy intake, the amount of fat intake is 68g, but the actual amount of fat intake was only 33g. With an increase of total energy intake, supply of calcium and vitamin A should be increased much more.
