This study was conducted to find out characterization of spatial distribution of birds observed in river areas. Our bird survey was carried out 4 times at 31 sites from January to September in 2011. A total of 1,609 accumulated individuals belonging to 59 species, 28 families and 11 orders were observed. In the result of spatial autocorrelation analysis using the richness index of the maximum counts of each sites, we confirmed that the distribution of birds in Namdaecheon river was clustered and the tendency of spatial autocorrelation was apparent. The area of each sites within a 200m radius was classified in four biotope categories such as agricultural land, forest, residential area and water area, and the spatial autocorrelation was analysed about four types. In the result of spatial autocorrelation analysis for four biotope categories, all types were showed the positive spatial autocorrelation, but the type of water area was higher than other types. The positive correlation was found between the water area and water birds in statistical significance. However, the forest birds had non-significance values. Therefore, it is appropriate to focus on water birds except for forest birds, when researches of bird distribution in river ecosystem is conducted. The number of bird species and individuals increased as the riverside of water area was to widen. Thus, if the areas of riverside offering the feeding and roosting area increase, it will be accommodated many birds. Also, the areas of riverside should be maintained naturally because it is an important habitats of birds. Our study area is on the outskirts the city of higher rates of forest and agricultural land, it may be unreasonable to apply our results to the whole rivers. If the research about the river flowing around the city will be conducted, it is expected to be useful to the relation study area such as ecological river's restoration.

Midtown redevelopment project is intended for restoration of city's declining function and promoting the utilization of land, but several factors such as participants of different nature in the project, different expectation level from them, high land value accompanied by geographical location as a city and the demand for high density development, nature of business that requires long duration to complete and vast amount of fund contribute to complication of feasibility study. Due to these characteristics of midtown redevelopment project, consideration of various factors involved with it and reliable analysis are required but suggested complication of feasibility study is causing halt in project, preventing from launching it and delaying it. So, this study was undertaken to be a help to feasibility study of midtown redevelopment project by suggesting main elements that need to be dealt with analysing questionnaire survey result attained from related expert in this area and arranging total 45 factors essential to feasibility study for midtown redevelopment project that can be classified into 5 main category such as economic/financial factors, legal/institutional factors, market related factors, technical factors and conflict related factors through documental investigation, case study and interview with specialist concerned.

This study investigates the different characteristics (mainly of community life) in representative intentional communities, between the ecovillage and cohousing, since the different purpose of the establishment of the community might result different characteristics. The study method is data analysis: the analysis material is Community Directory, A Comprehensive Guide to Intentional Communities and Cooperative Living (Rutledge, 2005). Of 750 listed communities, 397 (211 ecovillages and 186 cohousings) communities were analyzed. The findings of the study reveal that there are clear differences of community life between ecovillages and cohousings even though two communities are regarded as similar intentional communities. The similarities between the two communities are as follows: 1) Those mostly distributed in the USA, and established before 2000. 2) Dominant size of intentional communities is less than 20 residents and 20 houses. 3) They make decisions in consensus. 4) They eat together very frequently; at least once a week or more. 5) Shared work is required. The differences between the two communities are as follows: 1) They have different aims of establishment. For instance, ecovillage focus more on eco-living, while cohousing focuses more on the cohousing idea. 2) There are more female residents in cohousings than in ecovillages. 3) There are more cohousings in urban areas with a smaller area of land, contrary to that there are more ecovillages in rural areas with larger areas of land. 4) There are less identified leaders or leadership core groups in cohousing than in ecovillages. 5) Income sharing is more common in ecovillages than in cohousings. According to there findings, it is evident that a different purpose of establishment result in different characteristics of community life even though those belong to the similar category of the intentional community. Thus, it is recommended to adapt the correct characteristics that fit the aim of the community in the establishment an intentional community Topics and discussions about establishing intentional Topics and discussions abut establishing intentional communities could contribute to gather the intentional communities could contribute to gather the interests communities could contribute to gather the interests of residents as well as those of relevant civil-workers and administrators in Korea.

The mortality rate in industrial accidents in South Korea was 11 per 100,000 workers in 2015. It's five times higher than the OECD average. Economic losses due to industrial accidents continue to grow, reaching 19 trillion won much more than natural disaster losses equivalent to 1.1 trillion won. It requires fundamental changes according to industrial safety management. In this study, We classified the risk of accidents in industrial complex of Ulju-gun using spatial analytics and data mining. We collected 119 data on accident data, factory characteristics data, company information such as sales amount, capital stock, building information, weather information, official land price, etc. Through the pre-processing and data convergence process, the analysis dataset was constructed. Then we conducted geographically weighted regression with spatial factors affecting fire incidents and calculated the risk of fire accidents with analytical model for combining Boosting and CART (Classification and Regression Tree). We drew the main factors that affect the fire accident. The drawn main factors are deterioration of buildings, capital stock, employee number, officially assessed land price and height of building. Finally the predicted accident rates were divided into four class (risk category-alert, hazard, caution, and attention) with Jenks Natural Breaks Classification. It is divided by seeking to minimize each class's average deviation from the class mean, while maximizing each class's deviation from the means of the other groups. As the analysis results were also visualized on maps, the danger zone can be intuitively checked. It is judged to be available in different policy decisions for different types, such as those used by different types of risk ratings.

In this study, sample sites are chosen where digitalized cadastral maps are available, and boundaries of forestry, farming lands, and residence are clearly distinguishable. Digital orthophotos, produced from aerial photographs, are overlaid with digitalized cadastral maps to grope for applications of digital orthophoto in cadastre. The conclusions and applicable fields of this study are as follows. The first. digital orthophoto is applicable to solve problems such as discordance and duplication of boundary produced in the process of digitizing cadastral maps. The second, using digital orthophoto, it is possible to extract regions where a trouble of ownership would exist and so the necessity of cadastral resurveying can be brought. The third, by overlaying digital orthophoto and cadastral map, it can be used effectively for the present situation maintenance of buildings. The fourth, because it is possible to examine current land use of each lot, digital orthophoto may contribute to decide the validity of land category on cadastral map.

The purpose of this study is to analyze the effect that consumption patterns of human affect the ecosystem using analysis of ecological footprint(EF) and assessment of ecosystem service value in Daegu Metropolitan Area. The data for analysis were constructed from statistical yearbook of each city and average of public land price on land category. According to the EF analysis on city, total EF of Goryeong was showed the highest by 3.3052gha in 2007. However, total EF of Daegu was assessed the lowest by 2.0134gha among 8 cities. In the results of ecological deficit, 7 cities except Gunwi were assessed by condition of ecological deficit and had exceeded environmental capacity until 2007. Specially, it was analyzed that Daegu may need additional area more than about 30 times to maintain the present consumption patterns. On the one side, the results of analysis of ecosystem service value in Daegu were assessed that citizens of Daegu have borrowed about 1,078.6 million wons to ecosystem per year and one person.

This study attempted to predict citizens' emotions regarding mortgage rates using machine learning algorithms. To accomplish the research purpose, I reviewed the related literature and then set up two research questions. To find the answers to the research questions, I classified emotions according to Akman's classification and then predicted citizens' emotions on mortgage rates using six machine learning algorithms. The results showed that AdaBoost was the best classifier in all evaluation categories. However, the performance level of Naive Bayes was found to be lower than those of other classifiers. Also, this study conducted a ROC analysis to identify which classifier predicts each emotion category well. The results demonstrated that AdaBoost was the best predictor of the residents' emotions on home mortgage rates in all emotion categories. However, in the sadness class, the performance levels of the six algorithms used in this study were much lower than those in the other emotion categories.

This study aims to analyze the current status of government-designated cultural heritage that are protected as sacred natural sites, focused on natural monuments and scenic sites, and provide basic research for these cultural heritage to be included in the protected area category. First, among natural cultural heritage that are designated and protected by Cultural heritage Protection Law, there are 40 scenic sites and 126 natural monuments that have been selected as sacred nature sites. Second, the study showed that sacred nature sites are sacred places that have been long associated with happiness and misfortune of the villagers, including Dangsan Forest, Seunghwanglim(Forest), and, as physical environment and combination of cultural value, rules, and attitude and belief system toward the land that protect the people. The unique folk beliefs of the region provide strong protection of the place. Third, although the natural monuments of old and large trees are not included in the protected area as they are recognized sparsely, but can be designated as world protected area as protected areas are set around sacred nature sites. Fourth, in order to be included in IUCN category, sacred natural sites of scenic sites will need to be managed by specific categories of each area according to the interior status of the designated areas and maintain the sustainability of the natural heritage by protecting both physical and spiritual elements.

Since rapid industrialization of Korean society, out-of-village roads have been greatly improved, while almost all of in-village roads have not been fundamentally improved yet. Unless village roads should be improved in relatively comparison with trunk roads, it has been widely recognized that grass rooted achievement of accessibility revolution not be realized. In this regard, this study tried to develop evaluation indicators system for improvement of village roads. The evaluation indicator system on village road conditions was proposed which is sub-categorized as structural improvement of road itself, its communication serviceability and public securing level of property rights of road site. The system has 6 indicators(2 of each subcategory);good pavement ratio and over 3m wide road length ratio, ratio of household fronting under 2m wide road and connectivity of road network, ratio of registered as 'road' in land category and ratio of publicly owned road sites. In the final conclusion, village roads in rural Korea have been generally in worse condition regardless of whether prior improvement works or not, except some of recent plan-based improvement villages.
