This study has focused on geomorphological landscape resources analysis at the Dong-gang River Ecological and Landscape Conservation Area through literature review and field survey. Some appropriate maps have been created for this study. This study intends to examine the distribution characteristics of geomorphological landscape resources at the Dong-gang River Ecological and Landscape Conservation Area, and suggests a solution to manage and maintain the resources. The result has shown that the resources can be divided into four categories : The Dong-gang`s riverside geomorphological landscape resources, Pyeongchang-gun Hantan-ri`s plateau and karst area, limestone caves in various sizes throughout the entire study area, and the mountainous regions close to the study area boundaries. The study concluded that these geomorphological landscape resources are partially damaged or likely to be damaged due to tourist inflow and also the quality of resident lives needs to be improved. Therefore, limiting the number of tourists entering the area or installing guides who provide information about the academic importance of such resources are necessary in terms of maintenance. There is also a need for a customized solution according to geomorphological landscape resources in order to secure benefits for the residents as well.

During the condylar shaving procedure, the articular soft tissue cover can be removed. Author compaired the histological healing process of the articular soft tissue cover between the preservative and unpreservative group group with 45 New Zealand rabbits(Average wt. : about 2.5kg). In unpreservative group, the usual high condylar shave with the removal of soft tissue cover was performed. In the preservative group, the underlying bone, replaced in its original position and sutured. The animals were sacrified 1, 2, 3, 4, 6 weeks interval after operation. The specimens were fixed in 10% neutral formalin and decalcified, paraffin embedded and stained by Hematoxylin & Eosin, and Masson's trichrome. The obtained results were as follows. 1. The condyles of the both group were covered with an articular sop tissue layer. 2. The cartilage cells in subarticular layer has regular continuous patterns in the preservative group but frequently interrupted in the unpreservative group. 3. The incision made in the posterior part of the articular surface for the elevation of the articular soft tissue frequently caused a deformity such as the interruption of the subarticular layer of cartilage. 4. By the above findings, the preservation of articular sop tissue cover may be the effective operation method on concept of bone remodelling.

The crystallinity, crystallite sizes and orientation of hemp fibers treated in caustic soda of various concentration with and without constraint were measured by wide angle X-ray diffraction method. It was found that, 1) The crystallinity monotonously decreased with the increase of caustic soda in the samples treated with constraint, whereas it decreased and again increased with the increase of alkali concentrations in the samples treated without constraint. 2) Crystallite sizes of 002 plane decreased with increase of alkali concentrations, more remarkable decrease occured in the samples treated with constraint, And there were no significant changes on the crystallite sizes of 040 plane in the samples treated with and without constraint. 3) The orientation increased in the samples treated with constraint, whereas it decreased in the samples treated without constraint. The foregoing observations indicate that it is advisible to avoid high alkali concentration and excess tension.

In this study, we detected and predicted changes in terms of land categories of Seosan-si using land category data. We also evaluated flood vulnerability due to the rise in sea level based on the past sea level recovery data and IPCC SRES scenario. As a method of predicting land category, this study applied the double exponentially smoothing method. Results of the time series analysis using land category data revealed that paddy, artificial structure, water, grass field and bare land areas increased, but forest, marsh and dry field areas decreased. The results of predicting changes in land category using double exponentially smoothing showed that forest, grass field, marsh, paddy and dry field areas will continue to decrease from 2010 to 2050, but water, artificial structure and bare land areas are expected to increase continuously. Through flood vulnerability assessment, it was analyzed that flood-affected areas in artificial structure, paddy, dry field and bare land areas increased, but those in forest, water and marsh areas decreased. In particular, the risk of flooding in agricultural land and artificial structure increased, but that in marsh and forest areas decreased. It is estimated that the increase and decrease in inundation areas is caused by changes in land use resulting from industrialization and urbanization due to the construction of industrial complexes and development of tourist resorts that takes place in coastal areas.

This study attempted to assess the flood risk of coastal regions in the Chungnam province based on rise in sea level by their type of land-cover. We have analysed changes according to the respective IPCC SRES scenario using quantitative GIS method on multi-temporal satellite images. As a result of classification of landcover, grass fields, lakes and fish farms, marshes, and artificial structures have been steadily increasing, but forest, dry fields, and bare land steadily decreasing on the coastal regions in the Chungnam province. Based on the classified land-cover maps, we estimated the change of the land-cover. The results showed that grass fields, lakes and fish farms, marshes, and artificial structures would increase, but paddies, dry fields, and forest would decrease. From the assessment of the flood risk based on rise in sea level by their type of land-cover, grass fields, lakes and fish farms, dry fields, and artificial structures are probable to be flooded. For cities and Guns on coastal regions in the Chungnam province, the flood risk of the artificial structures is high in all the cities and Guns. In particular, it is probable to be flooded on beaches in Boryeong, marshes in Seosan, lakes, fish farms, and paddies in Taean, lakes, fish farms, and marshes in Seocheon. In addition, it is probable to be flooded on lakes and fish farms in Dangjin and Hongseong.

In this study, we analyzed the changes in the wetland area using multi-temporal aerial photographs of the mountainous wetland at Shinbul Mountain. It also promoted a vulnerability assessment for the climate change in the mountainous wetland through a significance test of the wetland area change using the climate data. The result shows no significant change in the annual mean precipitation, whereas the annual mean temperature generally increases. Therefore, it is considered that the climate data more largely influencing the changes in the wetlands of the observed area is the increase in temperature, rather than the precipitation, regarding the changes in the distribution of vegetation in the wetland. Based on the analysis of the multi-temporal aerial photograph, it was found that most of the wetlands decreased in terms of area. In particular, the areas of A and C wetlands continuously decreased. On the other hand, wetland B decreased until the 1970`s but slightly increased in the 1980`s. It started to decrease again afterwards. Wetland D generally decreased in the beginning, but started to rapidly increase since the 1990s with the wetlands restoration project. Considering changes in the areas of wetlands on the whole, all the areas except wetland D have been continuously decreased. This change in the wetlands ecosystem is attributed to the increase in temperature as well as the inflow of earth and sands during rainfalls, and erosion contributed by mountain climbers.

The study is focused on the analysis of geomorphological environment changes of alluvial bar in the lower Kum River using satellite-based multitemporal/multisensor data. Landsat datas for environment changes analysis consists of Landsat MSS(2 scenes) and Landsat TM(7 scenes) acquired from 1979 to 1994. This study is to develop the analysis techniques for the environment change detection of using ratio, classification, false color composite etc, of Landsat data especially useful to the geomorphological study of tidal flats and river channels. The results of this study can be summarized as follows: 1. The lower Kum River alluvial bar have had rapid geomorphological changes after the construction of the temporary dam to block the river flowing in 1983. The most alluvial bar located in the river has both bankway growth, especially the alluvial bar in the Lower Kum River had grown between 1983 to 1990. 2. After construction of the estuarine barrage, no remarkable geomorphological changes have been found in Kum River area but the growth and formation of new underwater bar has continued. The enormous materials was needed for the growth and formations of new underwater barrier islands and bar would be supplied from the sea bottom and the river sediment to diminish of stream velocity after construction of the estuarine barrage.

The purpose of this study is to analyze the land cover environmental changes in the Anmyeon-do. Especially, it centers on the changes in the land cover environment through methods of GIS and remote sensing. The land cover environmental change areas were detected from remote sensing data, and geographic data sets related to land cover environment change were built as a spatial database in GIS. Fuzzy logic was applied for data representation and integration of thematic maps. In the natural, social, and economic environment variables, the altitude, population density, and the national land use planning showed higher fuzzy membership values, respectively. After integrating all thematic maps using fuzzy logic operation, it is possible to predict the change quantitatively. In the study area, a region where land cover change will be likely to occur is the one on a plain near the shoreline. In particular, the hills of less than 5% slope and less than 15m altitude, adjacent to the ocean, were quite vulnerable to the aggravation of coastal environment on account of current, large-scale development. In conclusions, it is expected that the generalized scheme used in this study is regarded as one of effective methodologies for land cover environmental change detection from geographic data.
