The purpose of this study is to explore the methods to activate and functional changes of rural centers to improve residents' quality of life and secure sustainability in rural areas. The existing policy for activating rural centers lacks for placeness because walking-focused features of a Myeon seat have been changed due to the improvement of physical environment for easy car accessibility. They also wanted to solve abandoned houses and secure parking lots in the landscape plan. Based on analysis results, design guidelines were suggested. Long-stay tourism programs for outside visitors should be developed through the rural center activation project. They should be linked with projects for preserving the history of Byeongyeong Fortress and developing Hamel Village. Mountain trails and waterfront should be created to enhance accessibility and linkage methods with other resources should be prepared. As Byeongyeong-myeon has various tourism resources, design guidelines for each element should be made for a macroscopic direction and systematic landscape management.

Numerical analysis performed to predict the behavior of Ipseok-dae columnar joints in Mudeungsan National Park to understand their stability and movement. The numerical analysis technique, 3DEC, is based on the discrete element method that can analysis discontinuities. The analysis used data for material properties derived from laboratory tests, which found that average density was 2.68 kN/m³, average normal stiffness was 3.15 GPa/m, average shear stiffness was 1.00 GPa/m, average cohesion was 0.51 MPa, and the average friction angle was 33°. The Ipseok-dae columnar joints were modeled on the basis of the field survey data for 15 joints located between the observation platform and the hiking trail. The numerical analysis assessed the behavior of each columnar joint by interpreting the displacement of the edges of its upper and lower surfaces. The greatest maximum displacement was found in columnar joint No. 6, and the greatest minimum displacement was found in joint No. 11. Analyzing the movements of five discontinuities in joint No. 11 indicated that the maximum displacement occurred at the 2nd level. The other levels were ordered 5th, 4th, 1st, and 3rd in terms of subsequent greatest displacements. Considering the total displacement in the 15 studied joints, the Ipseok-dae columnar joints are judged to be stable. However, considering the cultural and historical value of Mudeungsan National Park, it is regarded that the currents slope stability should be maintained by monitoring the individual rock blocks of the joints.

The rare and endangered plants in Naesorak area were investigated for four months during May to August in 1997, and the results were summarized as 35 taxa which is classified as 19 families, 32 species, and 3 varieties. At the level of families, 19 families such as Pinaceae(1 species), Taxaceae(1 species), Cupressaceae(1 species and 1 variety), Liliaceae(5 species and 1 variety), Aristolochiaceae(2 species), Ranunculaceae(4 species), Berberidaceae(1 species), Saxifragaceae(2 species), Rosaceae(1 species), Oleaceae(2 species and 1 variety), Solanaceae(1 species), Scrophulariaceae(1 species), Valerianaceae(1 species), Campanulaceae(1species), and Compositae(1 species) were recorded. The most of the habitats of the species was easily found along the major mountain trails, and a kind of destructions of these plants by human interferences is due to the fact that the illegal collections for food and medicine are occurred. Those species of Taxus caespitosa, Rhododendron aureum, Vaccinium bracteatum, Allium victoralis var. platyphullum and Leontice microryncha has a few individuals in habitats and also shows the unfavorable growing state, so the intensive and continuous habitat management of the habitats were inevitably dimanded.

A vegetation survey was conducted and analyzed on 25 survey plots of Betula ermanii communities in the subalpine zone of Mt. Gariwang, Mt. Balwang, Mt. Bangtae, and Mt. Hambaek in Gangwon-do. As a result of TWINSPAN and DCA analysis, the community was divided into a total of 3 communities: Betula ermanii-Quercus mongolica community(GroupI), Betula ermanii-Acer pseudosieboldianum community (GroupII), and Betula ermanii community(GroupIII). As a result of the vegetation structure analysis, Betula ermanii-Quercus mongolica community(GroupI) is located on the periphery of the Mt. Bangtae trail at altitude of 1,082~1,192m, and Betula ermanii-Acer pseudosieboldianum community(GroupII) is located on the ridges and slopes of Mt. Bangtae, Mt. Gariwang, and Mt. Hambaek at altitudes of 1,230~1,373m. Betula ermanii-Quercus mongolica community(GroupI) and Betula ermanii-Acer pseudosieboldianum community(GroupII) are currently dominated by Betula ermanii, but after long term, it is expected that they will transe to Quercus mongolica. The Betula ermanii community(GroupIII) is located the summit of Mt. Hambaek and the summit of Mt. Balwang at altitude of 1,428~1,464m. It is expected that the community will be maintained as Betula ermanii community, because Betula ermanii is very dominant, and so the next generation dominant species is maintained by Betula ermanii. Betula ermanii community generally appear above 1,000 m above sea level, and the higher the altitude, the more dominant the Betula ermanii are. As a result of the soil analysis, the soil characteristics shows a similar pattern to the subalpine belt of Daecheongbong Peak of Mt. Seoraksan and Banyabong Peak of Mt. Jirisan. As a result of the species diversity index analysis, the species diversity index was 1.210~1.293, the abundance index was 0.698~0.795, and the dominance index was 0.208~0.302.

This Study attempted to comprehend difference between hiker and non-hiker's sense of place value at Namhansanseong Provincial Park. Especially, it was analyzed after visitors, who were divided into local residents & tourists and first time visitors & repeat visitors. Out of 600 visitors, who were over 19 years old, participated in the survey, 587 responses were used for data analysis. Consequently, Sense of place value at Namhansanseong Provincial Park were classified into three factors: Health Culture, Ecology Environment, and Connectedness. Hikers feel higher value on promotion of health, relaxation, environment than non-hikers. Among hikers, local residents feel higher value on ecology environment and connectedness than tourists. Among non-hikers, however, they have no difference between local residents and tourists, only repeat visitors and first time visitors. On this result, possibility of resident participation management on natural environment and trail was considered, and when the program, which is for raising cultural and traditional value, would develop, increasing number of repeat visitor should be considered as a high priority.

The object of this study was to examine and analyze the environmental deterioration of three major trails and around peak area of Moaksan Provincial park in 1996. Trails are mostly made up at ridgeline and the slope of them is gentle. Mean trail width is 3.6m, and total length of branch trails is 982m in survey area. The environmental deterioration is derived from trail extension. Maximum eroded depth and cross-section area loss are 89cm and 14,050cm2 respectively, and gully erosion type appears at many sites. The environmental deterioration of trails is very heavy at the sections from Khui to Moaksan peak and from Moakchong to ascent part around the peak. The entire width, branch trail, maximum depth, cross-sectional area loss and surface roughness, as the indexes of trail conditions, are significantly greater at the more heavily used trails. Amount of erosion is influenced by eroded depth, longitudinal slope, runoff influence and entire width in descending order as well as the amount of use. Safety and protection facilities on the trail such as stone and soil stairs, rope handrail, stone channel and soil ditch work are built, but they are very deficient. Bared lands about 4,900m2 and fill slopes are caused and formed by recreation activities and constructions around peak area. It is required to carry the recess system and to conserve and rehabilitate the destroyed trail sites and bare fill slopes as soon as possible, before the environmental deterioration becomes critical because of increased used amount in consequence of construction of recreation parks.

Drug-induced Parkinsonism is the most frequently observed type among the cases of secondary Parkinsonism. Besides typical parkinsonian symptoms, such as tremor, rigidity and bradykinesia, drug-induced Parkinsonism manifests with additional simultaneous symptoms like orobuccolingual dyskinesia, mixed type of tremor (resting, action), and symmetry of expressions. We present a case of drug-induced Parkinsonism, affected by taking the antiulcer drug cimetidine. Jodeung-san extract (Choto-san, Tsumura Co. 10) was administered for 7 days and acupuncture (electronic, auricular, pharmacopuncture) was conducted 3 times. The clinical outcomes were then evaluated through the patient's global impression of change, visual analogue scale, and Hoehn and Yahr stage. After the treatment, the clinical features, such as tremor and orobuccolingual dyskinesia, disappeared. The combination of Jodeung-san and electro-acupuncture at GB34 could therefore be a remedy for the patients with drug-induced Parkinsonism.
