최근 국내 폐기물 매립지는 대규모의 부지를 조성할 수 있는 해안의 점토지반 상에 시공되고 있으며 차수층의 강도증진과 차수층 바닥을 통한 침출수의 유출을 방지하기 위해 시멘트 고화 차수재를 많이 사용하고 있다. 그러나 점토 차수층에 비해 큰 강성을 가지고 있는 시멘트 차수층은 매립되는 쓰레기 하중에 따라 침하가 동반되고, 부등 침하가 발생할 경우 차수층에 균열이 발생될 수 있다. 본 연구에서는 폐기물 침출수의 유출을 방지하기 위해 Go매립지 점토를 혼합하여 만든 자가형성(Self-Sealing) 및 자가치유(Self-Healing) 차수층의 적용성을 평가하기 위해 삼축투수시험과 일축압축시험을 실시하였으며, 국내에 폭 넓게 분포하는 화강풍화토를 혼합하여 SSSH 차수층을 시공할 경우, 본 공법이 적용 가능한지를 평가하기 위해 자가형성(Self-Sealing)에 대한 시험을 실시하였다. 그 결과 점토가 혼합된 SSSH 차수재의 투수계수는 폐기물 관리법에서 요구하는 기준치보다 작은 값을 갖고 있었으며 일축압축강도 역시 증가되는 경향을 나타내었고, 화강풍화토와 벤토나이트가 혼합된 SSSH 차수재는 점토만을 사용한 경우보다 좋은 개량효과를 보였다.

Aerial videography techniques have been used to inventory conditions associated with grassland, forests, and agricultural crop production. Most recently, aerial videography has been used to verity satellite image classifications as part of the natural ecosystem survey. The objectives of this study were: (1) to use aerial video images of the study area, one part of Taean Seashore National Park, for the accuracy assessment, and (2) to determine the suitability of aerial videography as an accuracy assessment, of the land cover classification with Landsat-TM data. Video images were collected twice, summer and winter seasons, and divided into two kinds of images, wide angle and narrow angle images. Accuracy assessment methods include the calculation of the error matrix, the overall accuracy and kappa coefficient of agreement. This study indicates that aerial videography is an effective tool for accuracy assessment of the satellite image classifications of which features are relatively large and continuous. And it would be possible to overcome the limits of the present natural ecosystem survey method.

The objective of this study is to survey environmental substances for the preservation of the seashore national park. The sea water near Tae- An national park was clear but the water of the harbor was polluted with wastewater from ships and sewage. The sea water at the bathing resorts was clear but may be polluted by wastewater from near by sea water. The public environmental index containing air, water, noise, open space and land scape of Tae- An seashore national park was high The concentration of total suspended solids in the air was lower than that of standard levels. When the surroundings of the national park are developed, the effects of development will be estimated.

For concrete structures immersed in seawater, the concentration of chloride used to estimate the chloride diffusion coefficient can be defined as the seawater chloride concentration. However, for seashore concrete structures which are not coming into direct contact with seawater, establishing the interface concentration of chloride becomes delicate. In addition, concrete structures are greatly affected by salt attack primarily due to airborne sea salt like it can be seen through the corrosion of rebar. This study intends to investigate characteristics on the salinity of airborne sea salt by height. Salinity measurement devices were installed at height of 2, 10 and 19m on the seashore water tower located in the area of Samchuk in the Eastern coast. Analysis results of the decrease of salinity with respect to the height above the ground at a distance of 30m from the seashore showed that the reduction reached about 40$\%$ at a height of 10m and 60$\%$ at 20m.

Concrete structures in the seashore are greatly affected by salt attack primarily due to airborne chlorides like it can be seen through the corrosion of rebar. This study intends to investigate characteristics on the salinity of the airborne chlorides in terms of areas. Salinity measurement devices were installed at 27 areas along with seashore throughout the country. The area index for airborne chlorides were established according to the measurements. In Gochang and Taean area showed higher value of area index over 10. In addition, the Eastern coast showed higher index compared to the Western and Southern coast.

Background: Cliffs are a major plant habitat around the coastal area, but in contrast to sand dunes and salt marshes, they have been little investigated in Korea. There are simple descriptions of cliff vegetation in studies on island vegetation, but there is no published paper, which addressed sea cliff vegetation synthetically. Furthermore, the coastal area where this study was carried out was designated as a conservation reserve. Even though, this area is exposed to intense recreational use such as trekking in these days. This study aims to clarify spatial distribution and structure of vegetation along the environmental gradient on coastal cliff and plateau in the Janggi peninsula (Homigot) located on southeastern Korea. Further, this study has also another objective to prepare a restoration plan to protect this conservation reserve from intense human disturbance. Results: Landscape elements were arranged in the order of sea cliff risen directly on the sea, seashore, coastal cliff, and plateau covered with relatively deep soil in a coastal area of the Janggi peninsula (Homigot), southeastern Korea. Vegetation was sampled at 59 plots arranged from the sea cliff through the seashore and coastal cliff to plateau. The sea cliff, seashore, and coastal cliff, which compose the coastal landscape, were dominated by the seashore spatulate aster (Aster spathulifolius Maxim.) community, dwarf sand sedge (Carex pumila Thunb.) community, and seashore spatulate aster (Aster spathulifolius Maxim.) community. On the plateau corresponding to the ridge of the coastal cliff, black pine (Pinus thunbergii Parl.) community, golden rain tree (Koelreuteria paniculata Laxmann) community, east Asian hackberry (Celtis sinensis Pers.) community, sawleaf zelkova (Zelkova serrata Makino) community, and Korean oak (Quercus dentata Thunb.) community were established in the mentioned order along distance from the sea. Stand ordination showed a vegetation sequence from the seashore through the cliff to the plateau, consistent in its overall pattern among sites. This was dominated by topography. There is evidence for the importance also of salinity, drought and of soil depth. Conclusion: The lack of scientific interest in cliffs to date is in striking contrast to the commonness of cliffs around the whole national territory and to the attraction cliffs have had for humans throughout history. Cliffs provide a unique habitat, rarely investigated from an ecological viewpoint. Cliffs may represent an invaluable type of ecosystem, consisting of some of the least disturbed habitats on earth and contributing more to the biodiversity of a region than their surface coverage would indicate. Although this coastal area where this study was carried out was designated as a conservation reserve, this area is in danger of severe disturbance due to excessive recreational use. We recommended a restoration plan to protect this area from such a disturbance.

Chloride ions are considered to be the major cause of steel corrosion in concrete structures exposed to seashore environments. Thus, estimating chloride ion concentrations by ages is needed to predict service life of seashore structures. Experimentally measured chloride profiles were used in this study for estimating chloride diffusion coefficients, and a relationship between mixing properties and chloride diffusion coefficients is proposed for predicting chloride penetrations.
