Abstract:The objective of this study was to map the distribution pattern of gentrification, showing the adverse effect of urban parks. The study adopted the perspective that urban parks, which have thus far been featured in urban planning without much criticism, may actually bring about unintended effects. This study employed a theory of gentrification that has received increasing interest in urban sociology to investigate the other side of the gentrification phenomenon. We identified urban parks as the cause of the gentrification from the start, and verified and visualised the phenomenon in the case of the Gyeongui Line Forest Park. We determined that the area with the higher possibility of gentrification was that within 600 m of the park. Big data accumulated over the past decade were used to prepare a proactive, systematic procedure to address gentrification, which is materialising in diverse forms. Through this study, we contribute to debates on the environmental justice of urban parks. Small changes in urban space can strongly affect our healthy lifestyles and urban sustainability. From this perspective, our study's research process and its results could provide indications of how to structure and manage new urban planning projects in the future.

: The purpose of this study is to analyze the landscape preference and landscape images of the Agricultural Aqueduct Bridges(AAB) by several different criteria. Semantic Differential Scale(SD scale) with landscape adjectives and landscape preference are used to estimate the alternatives of the AAB. The statistic methods such as descriptive analysis, t-test, factor analysis and regression, cluster analysis, are operated. The landscape preference of the alternatives is generally positive, 3.977 out of 7.000. The gate type is the most preferred, but the road-along type is the worst, by the location types. The simple repair type is the worst preferred, but total remodeling is the most, by the repair types. The characteristics of the AAB are analyzed and 4 factors of visual landscape are contracted; interest, orderliness, naturality and spatiality. Cumulative factor loading of these factors is about 65%, which is quite high. The higher and bigger AAB's are preferred, and the advanced finishing materials are also preferred, such as aluminum or wood panels. The long span is also preferred and the high repair cost would be preferred. But in this study, the cost-benefit analysis is not included, so it is recommended to research further, considering the cost variable with the visual factors.

: The purpose of this study is to review foreign scenic inventory map for the systematic management of natural scenic resources. Several foreign cases were surveyed and analyzed to apply the scenery inventory map in domestic, such as Visual Resource Management(VRM) from United States Bureau of Land Management, Scenery Management System(SMS) from USDA Forest Service and Visual Landscape Inventory(VLI) from British Columbia Ministry of Forest's, that were already established scenery inventory maps. The results are as follows. First, the characteristic of Korean landscape is quite a different from those of north american's, which is much smaller and more complex in topography and land use. So, it would be difficult to apply foreign system directly and we need more researches to our own system. The multi-stepped landscape unit system is highly recommended.Second, scenic quality could be estimated by the pre-built database, such as land forms, vegetation, hydrology and land uses.Historical and cultural attributes should be complemented. Third, existing scenic integrity could be grasped by scenic damage, landscape alteration caused by human activities and land exfoliation. Also, subjective evaluation method should be supplemented by objective criteria through further detailed studies. Finally, about landscape view conditions, landscape control points should be surveyed and established in advance, and viewing distance, viewing frequency, amount of observers and public interests should be considered.
