The functions of urban park including health related benefit and climate adaptation and mitigation are expanding. However, in-depth research and discourse on the equitable distribution of expanded park function has been limited so far. Following research suggests Green Welfare concept to reflect distributive equity and multifunctionality in the process of urban park policy development and execution. This study developed park welfare indices to analyze disparities of neighborhood urban park(NUP) distribution viewed from green welfare by literature review. The findings analyzed through the Correlation Analysis and Cluster Analysis by SPSS 18.0. The results of the study are as follows. First, green welfare is defined as "to receive equitable benefits and participate in the delivery process of green services which are promoting health and securing safety from climate change risks for every citizen by life cycle regardless of socioeconomic status". Second, NUP per person in Seoul indicate meaningful differences by socioeconomic and environmental status of Seoul administrative districts. Park welfare indices correlated to NUP per person were shown population density(negative), percentage of individuals $aged{\geq}65$(positive), percentage of self-reliance of local finance(positive), flood and air pollution vulnerability by climate change(negative). Third, the cluster analysis identifies three significant clusters that indicate differences of park welfare level. Thus, it was found that NUP in Seoul from a green welfare perspective was provided disproportionately. Future urban park policy in Seoul was required equitable distribution of multifunctionality of park beyond quantitative expansion, and priority consideration should be given to park service consumer.

This study aims to effective survey on actual condition for impact and vulnerability assessment on climate change in agriculture and rural community (limited to rural water and agricultural infrastructure, Paragraph 3, Article 2 of the Rearrangement of Agricultural and Fishing Villages Act) entrusted to Korea Rural Community Corporation based on the Law (Paragraph 2, Article 47 of the Framework Act on Agriculture, Rural community and Food industry). The results are summarized as follows. The rural water was divided into three categories (abnormal climate, water use, and flood control), and 31 indicators were selected. The reservoirs were divided into four categories, and 20 indicators were selected. The pumping stations were divided into two categories, 7 indicators, and the drainage pump stations were divided into two categories, 5 indicators were chosen. A survey on actual condition of each indicator was conducted and the result of the impact assessment was calculated. The 65 rural water showed values ranged from 0.855 to 1.308. The reservoir ranged from 0.966 to 23.338 as a result of the impact assessment on the 16 indicators. The pumping station was able to calculate the results of the safety inspection and the thorough safety inspection, and the drainage pump station was able to calculate only the result of the safety inspection. It is judged that it will be necessary to secure and analyze data on indicators with no data in the future. The results of this research can be utilized as baseline data that can deal with climate change preemptively.

This study was conducted to investigate a stability trend within 6 above average and 4 blow average erosion control dams, which were selected by The Korean Association of Soil and Water Conservation and were built in 1990s in Gyeonggi and Gangwon Province. The study was aimed to measure rebound hardness of upstream face, flood way and downstream face from those dams selected by using 'Concrete Test Hammer'. The main purposes of the study are selection of compression strength prediction equation and scope of wavelength, which successfully demonstrate non-destructive test results for erosion control dams. There is an opportunity to increase disaster prevention ability when stability vulnerability of concrete erosion control dam is detected in a timely manner. Results of the compression strength investigation express that there is a consistency with visual inspection of stability that has been processed by The Korean Association of Soil and Water Conservation. We concluded that a prediction equation, which was developed by Architectural Institute of Japan (AIJ), shows highest suitability in Korean erosion control dams when stability investigation is performed. The detailed criteria for the test result are 'stable', 'detail inspection required' and 'poor' for over 300 $kgf/cm^2$, 250~300 $kgf/cm^2$ and below 250 $kgf/cm^2$ respectively. Standards for stability of Korean erosion control dam and a compression strength prediction equation (that corresponds to the standards of the stability) should be established on the basis of chronological data of erosion control dam compression strength. Systematical approach for stability inspection that carries out remodeling or repair when problem on erosion control structures are detected through visual inspection and simple stability test, is necessary for the future disaster prevention.
