The objective of this study is to suggest the possibility on land cover classification using hyperspectal imagery on area which includes lands and waters. After atmospheric correction as a preprocessing work was conducted on hyperspectral imagery acquired by airborne hyperspectral sensor CASI-1500, the effect of atmospheric correction to a few land cover class in before and after atmospheric correction was compared and analyzed. As the result of accuracy of land cover classification by highspectral imagery using reference data as airphoto and digital topographic map, maximum likelihood method represented overall accuracy as 67.0% and minimum distance method showed overall accuracy as 52.4%. Also product accuracy of land cover classification on road, dry field and green house, but that on river, forest, grassland showed low because the area of those was composed of complex object. Therefore, the study needs to select optimal band to classify specific object and to construct spectral library considering spectral characteristics of specific object.

The distributions of the copper plated(small) pan evaporation in both space and time are analysed with the data observed, and the lake and the potential evaportranspiration are estimated from the climatological data. These value are compared with each other and to the precipitation for deducing the seasonal amounts and variations of water budgets in the selected basins and regions. The meteorological factor which is closely associated with the small pan evaporation are hardly recognizable when they are used as the monthly values. The relationships among the small pan, the Class A pan and the lake evaporation are well correlated with each other with correlation coefficient of above 0.90, so it may be possible to derve other evaporations from knowing one evaporation. The ratio of the Class A pan and the lake evaporation to the small pan evaportion in annual are about 73% and 55%, repectively, except the mountaineous area where the values are about 10% less than those. The evapotranspiration reach about 40∼60% of the annumal precipitation, but in May and October two values are nearly same. The frequencies of the monthly evaportion in class intervals in the regions are also provided.

최근 기상변동성 증가와 극치수문사상의 발생빈도 증가로 인한 기상재해가 빈번하게 일어나고 있다. 이러한 기상현상으로 인한 재해의 예방을 위해서 사전에 위험을 인지하고 그 규모를 예측할 수 있는 여러 기법들이 기상레이더 또는 수치예보자료 등을 이용하여 개발 및 적용되고 있다. 이 과정에서 해결해야 할 여러 문제점들이 있는데, 우선 수치예보자료 또는 기상레이더자료를 종관기상관측소 및 자동기상관측지점의 지상관측 강수량과 연계하여 평가하는 과정이 필요하고, 현재시점에 형성되어 있는 강우장의 공간 이동 예측 기법이 확보되어야 할 것이다. 전북지역은 게릴라성 집중호우가 빈번한 산악형 강수와 산지유역의 급한 하천경사가 맞물려 인명 및 재산피해가 매년 발생하고 있으며, 과거 돌발홍수가 발생한 사례가 있어 이상기후 및 기후변화로 인한 홍수 위험도가 커질 것으로 전망되고 있다. 본 연구는 전라북도의 기상재해 예측모형 개발을 위한 사전 분석과정으로 전라북도지역에서 관측된 기존의 대규모 강수사상을 이용한 강수사상의 특성 분류 및 관측소간 공간상관성을 분석하는데 목적을 두고 있다. 강수사상의 특성분류를 통해 강수 발생형태에 따른 기상학적 영향인자, 강수의 발생량 및 이동특성 예측의 정도를 향상시킬 수 있으며, 분류 기법으로 SVM(support vector machine)을 이용한 자동분류를 적용한다. 또한 관측소간 공간상관성 분석을 위하여 각 관측소 강수량간의 조건부 확률을 이용한다. 예로써 부안관측소에 강수가 발 생했을 때, 부안관측소의 강수량 조건에 의한 전주관측소 강수량 확률을 다음과 같이 구성할 수 있다. �揚滑斂�수량�咀刮활�수량��. 공간상관성 분석과정에서 관측소간 강수 이동시간에 따른 강수 발생 시간의 차이 또한 고려하며, 과거 기상관측 자료의 분석을 통해 전라북도지역의 관측소간 강수발생의 공간적 상관성을 규명하고, 단기예측 모델 개발을 위한 기초자료로 활용할 수 있을 것이다. 또한, 기후변화시나리오에 의한 미래 강수량의 지역적 상세화 과정에도 본 연구를 통한 결과를 이용할 수 있을 것이라 판단된다.

This study was carried out the analysis of forest vegetation structure using the phytosociological methods by Braun-Blanquet from April to November in 2006. The results were summarized as follows. The forest vegetation was classified into 23 communities and 3 forest ecosystem types such as slope forest type, valley forest type and artificial forest type. By the actual vegetation map, Quercus mongolica forest was widely distributed in the area and Pinus densiflora forest and Quercus variabilis forest in the southern parts of the slope and valley forest mainly in valley area, respectively. The importance value in the Q. mongolica forest and artificial forest was absolutely high for the species dominated in tree layer. The typical valley species of Lindera erythrocarpa and Styrax japonica were abundantly occupied in the all layers. Species diversity indices of Alnus hirsta forest was the lowest as 0.2191, and that of valley forest was about 0.9, the highest among the all forest types.

Tree-ring dating can be used to date scientifically prehistoric timbers, historical buildings or woodcrafts. It gives a calendar year to each tree ring and produces the felling dates of logs or wood panels. In this study, we applied tree-ring dating to two medicine cabinets, known to be made in Kyônggi Province. Two cabinets were dated A.D. 1884 and 1874 to the last rings, respectively. Even with closed ages, two cabinets show different styles and structures. Tree-ring patterns indicated that the origins of woods for both cabinets would be near Sorak mountains and Kangneung area in Kangwon province.

This study was carried out to suggest plan of earth surface erosion by typifying landforms in Gwangeung Forest. Elements of landform were classifyed as hierachical system by scale. Scale for classification set a decision as four categories. We could classify landforms which level zero is 4 levels of elements, level one is 6, level two is twelve, level three is twenty seven. However, micro landforms of valley bottom which is hard to mapping made a categorization as upper valley, middle valley, artificial channel valley. Plan for soil erosion suggested yarding corridor, landform management for surroundings of slope and bridge using rock and gravel, road construction for forest management stable bedrock rather than soil layer, repose angles and piling up rocks for channel walls, and setting up buffer zone when forest thinning be carried out. The result of this research will be expected to provide information for forest management of mountainous areas by landform types.

Kangwondo area is mountainous and landslide is easily happened easily during the rainy period in summer time. Especially, when there is torrential downpour caused by the unusual weather change, there will be greater possibility to see landslide. Another reason behind landslide is the continuous forest fire in these several years. Since the surface of the earth has been changed by the fire, when rainfall comes, landslide just happens easily. Also, it is reported that landcover condition, excepted rainfall condition, is the most effect for determining landslide susceptibility area. In this study, it is determined a landslide vulnerable area and landcover information is extracted from four satellite image(Landsat TM), about the landslide vulnerable area, which is pictured for each year. And which distribution change is analyzed. also, NDVI picture is made and distribution change of vegetation vitality is analyzed to study that change of landcover have a effect on landslide. As a result, could know that forest and NDVI are decreasing in landslide vulnerable area.

At present, environmental monitoring of linear infrastructure is based mainly on field sampling. The 'integrated mapping' approach has received only limited attention from field scientists. The increased environmental regulation of corridor targets has required remote sensing research to develop a sensor or technique for targets ranging from 15 m to 100 m in swath width. In an attempt to identify the optimal remote sensing system for linear targets, an overview is provided of the application requirements and the technology currently available. The relative limitation of traditional remote sensing systems in such a linear application is briefly discussed. It is noted that airborne video could provide, in a cost-effective manner, information required for a very narrow and long strip target utilising the narrow view angle and dynamic stereo coverage. The value of this paper is warranted in proposing a new concept of video infrastructure monitoring as a future research direction in the recognition of sensor characteristics and limitations.

Carboxymethylcellulose(CMC) which is water-soluble fiber was manufactured by mercerization and etherification in the earlier study. Experimental parameters were conversion time for each step, concentration of reagent and temperature. To know the presence of functional group, CMC was analyzed by FT-IR(Fourier Transform Infrared) spectroscopy. Ethanol was recovered using evaporator and purity of ethanol analyzed by GC-MASS was 97% and 83% after mercerization and etherification respectively. For the pilot plant, if CMC is folded by 40 times it showed maximum efficiency. Maximum solubility was obtained when the ratio of NaOH and MCA is 3 : 4.5.
