The purpose of this study is to make and validate landslide susceptibility map using artificial neural network and GIS in Kangneung area. For this, topography, soil, forest, geology and land cover data sets were constructed as a spatial database in GIS. From the database, slope, aspect, curvature, water system, topographic type, soil texture, soil material, soil drainage, soil effective thickness, wood type, wood age, wood diameter, forest density, lithology, land cover, and lineament were used as the landslide occurrence factors. The weight of the each factor was calculated, and applied to make landslide susceptibility maps using artificial neural network. Then the maps were validated using rate curve method which can predict qualitatively the landslide occurrence. The landslide susceptibility map can be used to reduce associated hazards, and to plan land use and construction as basic data.

Objectives: This study aimed to analyze the status of dental care in underserved areas of Korea. Methods: This study targeted 229 cities in Korea. The analytical index was revised and supplemented with variables related to dental care, and the "oral health level" indexes were further selected to provide a total of 20 analytical indexes. All selected indexes were converted into T scores (cited by the Korea Health Promotion Institute) and subjectively weighted. Finally, the regional oral health indices and areas were derived. PASW Statistics 25.0 (SPSS Inc. Chicago, IL, USA) was used to analyze descriptive statistics. Results: Gyeongbuk Cheongsong-gun had the highest dental underserved index. The city with the highest regional oral health underserved index was Jeonnam Shinan-gun. Daegu Jung-gu had the lowest dental underserved index and regional oral health underserved index. Regional gaps existed between dental care and the regional oral health underserved index according to the city province (p<0.001). Conclusions: To continuously evaluate oral health conditions and projects centered on vulnerable areas, it is necessary to develop indicators to derive vulnerable areas for dental care and to develop effective public dental policies.

본 연구지역은 강원도 강릉시 사천면 노동리에 위치해 있다. 이 지역에서는 2000년 4월에 산불이 발생한 지역으로 사면에 목본이 거의 없고 초본이나 조립사업에 의해 작은 나무들이 식재 되어 있다. 연구지역 일대의 지질은 쥬라기 대보 화강암인 흑운모화강암으로 이루어져있다. 화강암으로 이루어진 본 연구지역에서는 토어(tor), 핵석(core stone) 등을 일부 확인할 수 있으며 유수의 침식을 많이 받은 능선이나 계곡을 따라 기반암이 노출되어 있다. (중략)

While characteristics of topography, soil, and vegetation coverage were surveyed, also surface runoff and soil erosion for each rainfall event were measured to analyze effect of change of land cover conditions in mountain areas, Yangyang, directly after wildfire. Fifteen rainfall events were taken in total during the survey period. The result of this survey appeared that the amount of surface runoff and soil erosion are a great difference between plots with rapidly recovered vegetation and bare plots after wildfire. The burned plots where vegetation recovered rapidly generated two times or more of surface runoff and soil erosion than control plots, as burned plots with bare soil showed about ten times of surface runoff and sediment than control plots. The result of correlation analysis between main parameters of the surface runoff and soil erosion presented that rainfall factors and vegetation factors had significant effects on runoff and soil erosion. The sensitivity of runoff and soil erosion showed specially high correlation with vegetation indices. If the land surface disturbed by wildfire are recovered by natural vegetation as time passes, runoff and soil erosion may be decreased gradually. Because runoff and soil erosion in the areas with rare vegetation or bare soil are generated continuously, the discriminated mediation strategies would be established as condition of each region.

이상기후기간동안 유역의 수문 변화는 강수변화와 기온변화 등 복합적인 상관관계에 의하여 나타난다. 우리나라 지역의 최근 강수변화는 연 강수량의 증가 추세를 보이나 기온 또한 상승하므로 강수효율의 연변화, 월변화 및 지역 변화특성의 분석이 필요하다. 본 연구에서는 강수변화와 기온변화의 상관관계로 나타나는 월강수량을 월 증발량으로 나눈 P-E비 즉 강수효율을 분석하였다. 이상기후기간과 평년에 대한 강수효율 분석 결과 강수량의 영향이 지배적이고 기온이 강수효율에 미치는 영향은 미미하다 하겠다. 일반적으로 연 강수효율은 엘리뇨>평년>라니냐기간 순으로 나타난다. 이러한 일반적 특성과 달리 도시화된 서울과 인천지역의 연강수효율은 기후에 따른 차이를 발견할 수 없으나 연 강수효율과 달리 월 강수효율변화는 매우 큼을 보였다. 고도 200m 이상인 점과 섬이라는 지역 특성으로 인하여 울릉도는 평년>라니냐>엘리뇨라는 타 지역과 상반된 강수효율 분포를 보였다. 남부지역으로 갈수록 엘리뇨해의 강수효율이 높은 것으로 보아 엘리뇨의 영향을 더 많이 받는 지역은 북부지역 보다는 남부지역 이라는 것을 알 수 있다. 엘니뇨해의 7, 8월의 강수효율이 높게 나타났으며 이는 엘니뇨해의 7, 8월의 강수량이 많다는 것을 의미한다. 또한 엘리뇨 기간 9, 10월 강수 효율은 평년에 비하여 낮게 나타났다. 라니냐해의 강수효율 분포를 살펴보면 6, 9월에 강수효율이 높게 나타났으며 11, 12월 강수효율이 평년에 비하여 낮게 나타났다. 서울, 강릉, 울릉, 부산, 광주, 여수, 제주지역의 강수효율이 타 지역에 비해 높게 나타났다. 서울, 부산, 광주 지역은 고도의 도시화로 인해, 강릉, 울릉도, 여수, 제주 지역은 해양과 인접한 지형적 특성 때문이라 판단된다. 강수효율 또한 강수량이 집중되는 5월부터 8월까지 증가하는 것으로 나타났다. 나머지 달은 대부분 감소하는 것으로 분석되었다.

This study was conducted to investigate the effect of highland (Daekwallyung, altitude of 800m above sea level) production of cucumber (Cucumis sativus L.) seedlings for retarding culture in lowland (Kangnung, altitude of 20m above sea level). Cucumbers (cv. Jangilbanbaek, Jeongsunyeoreum and Ginseollok) were raised during 25 days from 31st July to 25th August, and then planted under the rain-shelter at Kangnung 25th August. Mean and minimum temperature during raising seedlings at Daekwallyung, $20.9^{\circ}C$ and $16.1^{\circ}C$ were $3.7^{\circ}C$ and $5.3^{\circ}C$ lower than those of Kangnung, respectively. T/R ratio of the seedlings produced at Daekwallyung was lower than that of Kangnung, but chlorophyll contents were higher. Daekwallyung seedlings were higher female/male ratio compared with seedlings from Kangnung. Marketable yield from cucumber seedlings (cv. Jeongsunyeoreum) produced at Daekwallyung was 32% higher than that of Kangnung. These results showed that cucumber seedling raising place was Daekwallyung for the retarding culture during summer season, particularly, and the best cultivars was Baekchim (cv. Jeongsunyeoreum).

한국산 담수어류인 버들치(Moroco)속의 동버들개(M. percnums)는 한반도 이북에 서식하며 이남지역에는 분포하지 않는 것으로 보고되어 있었으나 본 형태연구 결과와 유전적 연구(Yang and Min, 1989) 결과, 강원도 강릉 경포호지역에서 동버들개가 서식 분포하는 것이 확인되어, 동버들개의 분포상 최남단 지역으로 보고하며, 한국산 버들치속 어류는 총 5종이 한반도 이남지역에 분포하는 것으로 확인되었다.

This study was aimed to examine the Landsat Enhanced Thematic Mapper Plus (ETM+) index, which matches well with the field survey data in the wildfire area of Gangneung, Gangweon Province, Korea. In the wildfire area NDVI (Normalized Difference Vegetation Index), SAVI (Soil Adjusted Vegetation Index), and Tasseled Cap Transformation Index (Brightness, Wetness, Greenness) were compared with field survey data. NDVI and SAVI were very useful in detecting the difference between the wildfire and non-wildfire area, but not so in classify the soil types in the wildfire area. The soil plane based on the Tasseled Cap Transformation showed a better result in classifying the soil types in the wildfire areas than NDVI and SAVI, and corresponded well with field survey data. Using a linear function based on greenness and wetness in the Tasseled Cap Transformation is expected to provide a more efficient and quicker method to classify wildfire areas.

The tendency of erosion and accretion of the coast has occurred by the wanton development of a shore so that establishing the plans of nature preservation and development according to shoreline change is in demand. In this study, six DGPS positioning are executed in the periodic interval of about 2 months to choose coastal area of Gangnung, Gangwon-do and the observation data which is post-processed about 50cm accuracies on the Gangnung regular service is compared with digital map in 1998 and digital chart in 2006. Comparing DGPS values with shoreline of digital map, we know that erosion has occurred locally around training dike placed in Gangmun harbor and in southern Namhangjin, many accretions has happened near the breakwater of Namhangjin region and partial accretion is occurring in the other area. Therefore DGPS which is an acquisition method suitable for GIS data input is in use to collect the horizontal data and it could be used effectively to measure the shoreline change of time series through the long-term continuous observation by the coastal development.
