The purpose of this study is to investigate Residents' Neighborship in the Habitat Housing. It is also aimed to promote the community and community sense. Questionary methods and Direct interview were used for the survey of residents in the Habitat Housing. SPSS 10.0 program use for a statistical analysis. Most of the low-income bracket residential district has few public spaces. Habitat residential areas also have difficulties in taking various spaces because of the small scale and few people. According to the answer to the questions about Habitat residential problems, many people need public spaces. Consequently, multipurpose spaces must be made for the Habitat residents' neighborship and their good lives.

Jeju Island is managed intensively in terms of environmental and ecological aspect because of its extraordinary ecosystem types comprising numerous rare, protected flora and fauna. To depict rapid change of habitat status in Jeju Island, the InVEST Habitat Quality model has been operated and compared analytically with the Eco-Natural map. The Habitat Quality map of Jeju Island is turned out to have similar inclination with Eco-Natural map. We compared the average habitat quality value in each Eco-natural map class in Jeju Island and the habitat quality value of first second third grade and non-included area decreased as 0.95 0.76, 0.53 and 0.37 in eco natural map respectively. Compared to biodiversity map based on biological investigation, the result of the InVEST habitat quality model can be simply obtained by land cover map with threat and sensitivity data. Further studies are needed to make explicit coefficients for Jeju Island and Korean peninsula, then the Habitat Quality model could be applied to past and future scenarios to analyze extent of habitat degradation in time series to help decision makers.

Korean goral (Nemorhaedus caudatus raddeanus) is one of the endangered species in Korea, and the rugged terrain of the Soraksan National Park (373㎢) is a critical habitat for the species. But the goral population is threatened by habitat fragmentation caused by roads and hiking trails. The objective of this study was to develop a potential habitat suitability model for Korean goral in the park, and the model was based on the concepts of fuzzy set theory and multi-criteria evaluation. The process of the suitability modeling could be divided into three steps. First, data for the modeling was collected by using field work and a literature survey. Collected data included 204 points of GPS data obtained through a goral trace survey and through the number of daily visitors to each hiking trail during the peak season of the park. Second, fuzzy set theory was employed for building a GIS data base related to environmental factors affecting the suitability of the goral habitat. Finally, a multiple-criteria evaluation was performed as the final step towards a goral habitat suitability model. The results of the study were as follows. First, characteristics of suitable habitats were the proximity to rock cliffs, scattered pine (Pinus densiflora) patches, ridges, the elevation of 700∼800m, and the aspect of south and southeast. Second, the habitat suitability model had a high classification accuracy of 93.9％ for the analysis site, and 95.7％ for the validation site at a cut off value of 0.5. Finally, 11.7％ of habitatwith more than 0.5 of habitat suitability index was affected by roads and hiking trails in the park.

This study was conducted to obtain the basic research about Siberian roe deer (Capreolus pygargus), and to establish a conservation area into Seoraksan(Mt.) National Park, South Korea. We recorded Siberian roe deer field signs (bedding sites, feeding areas, feces and tracks etc), and habitat variables such as nearest distance to the watercourse, trails, slope, aspect, forest type and land cover etc. from Jan. 2006 to Dec. 2007 in Seoraksan(Mt.) National Park. According to the research of habitat characteristics of Siberian roe deer inhabited in Seoraksan(Mt.) National Park preferred mixed forest consisted of aged forest and middle-aged forest on the gentle slope which was close to hydrosphere in the middle elevation area of altitude of 400~600m above sea level in Seoraksan(Mt.) National Park. The results indicated that Siberian roe deer appeared to prefer south slope or north slope during the snow season and west or east slope during the non-snow season. The area of most suitable habitat for Siberian roe deer in Seoraksan(Mt.) National Park was $128.5km^2$ (32% of the total area) followed by $244.3km^2$ buffer area (62.2% of the total area), and $22.9km^2$ unsuitable habitat area (5.8% of the total area), which means environmentally unsuitable habitat for Siberian roe deer was rare in Seoraksan(Mt.) National Park. Thus, the area classified as major area in Seoraksan(Mt.) National Park appeared to be most important for the protection of Siberian roe deer.

This study aimed to develop the HSI (Habitat Suitability Index) model of Cypripedium guttatum. and to verify this model by applying to the candidate sites for replacement habitat. The development of HSI and SI (Suitability Index) model was conducted based on the existing literature, field surveys, and expert opinions for information on ecological habitat characteristics. Seven variables were selected as habitat variables including mean maximum temperature in Jul.-Aug., lighting, slope, altitude, effective soil depth, soil texture, and artificial overexploitation (i.e. protected areas). HSI model was developed for C. guttaum based on these variables. This HSI model showed high applicability to selection and evaluation of replacement habitats for C. guttaum. Our findings could provide the basic information on habitat assessment to prevent the extinction of endangered C. guttatum. However, since there is a limitation that the survey data were insufficient, further field surveys should be conducted on several habitat types to improve the accuracy of the HSI model.

This study compared the differences between the Dendranthema boreale and Dendranthema indicum in their habitat, soil adaptability, species composition and community structure in Korea. More D. boreale distributed than D. indicum to in the place where high elevation and on the surface of low degree slope. Both D. boreale and D. indicum growed well in south-east direction of the slope. The soil pH of D. boreale and D. indicum was 6.1 and 7.1, respectively. Ca, Mg, Na and organic matter content of the soil of D. boreale habitat was significantly lower than that of the D. indicum habitat. There were 102 and 88 taxa, in D. boreale and D. indicum habitat, respectively. Both species generally distributed along with herbs than along with trees. The important species found in D. boreale habitat were Artemisia princeps (57.1%) and Humulus japonicus (33.3%), and the D. indicum habitat were Miscanthus sinensis (42.9%) and Lonicera japonica (38.1%). The D. boreale group was classified into Artemisia princeps, Crepidiastrum denticulatum, Miscanthus sinensis, Humulus japonicus, Pueraria lobata, Lespedeza bicolor, Lonicera japonica and Rubus crataegifolius community. The D. indicum group was classified into Artemisia capillaris, Peucedanum japonicum, Boehmeria pannosa, Pinus thunbergii, Lonicera japonica, Quercus acutissima and Robinia pseudoacacia community. There is a large difference bewteen D. boreale and D. indicum in their habitat, soil adaptability, species composition and community structure.
