This study attempts (1) to find effective urban design elements in consideration of both heavy rainfall hazard mitigation and green city planning and (2) to evaluate their effectiveness in the field, a natural disaster-prone urban district in Busan, Korea. The analytical matrix considering previous green city planning research and ICPP’s three factors of disaster risk suggests three main urban design elements that can be used against heavy-rainfall natural disaster, which elements include green roof, permeable urban surface, and rain water utilization facility. Rain water utilization facility is, however, introduced alone to the field analysis given that its effectiveness has not been fully tested in the previous studies. The field analysis using EPA-SWMM reveals the possible role of rain water utilization facilities in reducing the amount of the peak flow reduction as well as in expanding the runoff flow time. The analysis also suggests that a better result is expected when rain water utilization facilities with small-to-medium capacity are introduced in a dispersed way. The analytical results help guiding municipal governments’ hazard mitigation efforts in consideration of green city planning and also promoting future studies to make connections between green city and hazard resilient city planning efforts.

This study is conducted to setting up planning components of women-friendly housing complex by carrying out an exploratory survey on what women need in an apartment housing complex. Because, previous studies are macro-oriented discourse about the direction of the urban planning. In order to enhance feasibility of planning components, not only qualitative research but also quantitative research of factor analysis and AHP (Analytic Hierarchy Process) are used together. As a result, 32 sub-factors and 6 major factors are selected. According to importance, the 6 major factors are safety, childcare affinity, life convenience, pedestrian amenity, self feasibility and aesthetic landscape. Through that process, the planning components of women-friendly hosing complex was set up. This Criterion is expected to be used in planning housing-complex development in near future. In addition, this study need to go along and consider the various types of co-housing and expanded samples.

This study analyzes the regional economic effects of changes in interest rates. Since the regional differences of economic structure are relatively large in Korea, the effects may be not the same over regions. A multi-regional CGE model is used for the analysis. The multi-region SAM is constructed using the 2005 regional input-output table and the regional data. In the scenario analysis of 10% increase of the call rate, it is found that production goes down in most regions, except for Gyunggi, Daegu, Gyeongnam which are unaffected and for Incheon in which production increases. The relative prices decline in major industry sectors in most regions, while the relative price of real estate increases in all regions, primary metal products’ either increases or is unaffected depending on regions and the relative prices of the major industry sectors except for the construction sector’s increase in Chonnam. The reason of the regionally different ripple effects on production and relative price of the rise in interest rates seems due to different capital-intensity among regions. It is shown that the larger the capital intensity is in a industry sector or and a region, the larger decrease of production the sector or the region has.
