In this study, vulnerability of water resources to climate change was assessed in terms of flood, drought and water management. Criteria and indicators were employed for assessing the vulnerability. The criteria used to assess the vulnerability was sensitivity of the study area, the exposure to climate and the adaptability to climate change. These criteria were quantified and standardized using corresponding indicators. Vulnerability of water resources to climate change is assessed to be generally increasing over time. The appropriate watershed scales are the large drainage basin for national level vulnerability assessment and the small drainage basin for local one.

Both the selection of indicators and weights for them are critical issues in the vulnerability assessment. This study is to assess the air pollution vulnerability focused on ozone for 249 local jurisdictions using weights calculated by the entropy methodology and then examine the applicability of the methodology. We selected indicators for air pollution vulnerability assessment and standardized them. Subsequently, we calculated weights of each indicator using the entropy method and then integrated them into the vulnerability index. The exposure indicators consider meteorological and air pollution factors and the sensitivity of the local jurisdiction include variables on vulnerable areas and environments. The adaptive capacity contains socio-economic characteristics, health care capacities and air pollution managemental factors. The results show that Hwaseong-si, Gwangjin-gu, Gimpo-si, Gwangju-si, Gunpo-si are among the highest vulnerabilities based on the simple aggregation of indicators. And vulnerability-resilience (VRI) aggregation results indicates the similar spatial pattern with the simple aggregation outcomes. This article extends current climate change vulnerability assessment studies by adopting the entropy method to evaluate relative usefulness of data. In addition, the results can be used for developing customized adaptation policies for each jurisdiction reflecting vulnerable aspects.

Fire stations should be located in optimal location to act quickly in case of emergency and minimize damages as a public facility that protects life and property of local residents. Siting fire stations without regard for the accessibility and occurrence factors of an accident may provide fire service unequally. Therefore service analysis is necessary to reduce the blind spot of disaster and safety and to offer equal fire-service at this time. Especially fire stations can service more efficiently than before by reducing a more likely vulnerable area. This study suggests methods of mapping index of value that represents vulnerability of the occurrence of an accident and extracting service zone map of fire stations, as an initial research for offering efficient fire service. Geographical distribution mismatch between service zone map and vulnerability map is figured out and vulnerable area for fire service is defined by using map overlay method.

기후변화로 인한 다년 가뭄은 매년 증가하여, 충청남도에 위치한 보령댐과 보령댐으로부터 용수를 공급받는 지자체의 시민들 또한 2015년부터 2017년까지 지속된 가뭄으로 인해 총 127일 동안의 생 공용수 급수조정으로 인한 불편함을 경험하였다. 지금까지 시행된 국내의 다양한 가뭄 피해 저감 정책 설립 과정은 대부분 일방적인 하향식(top-down) 의사결정 과정을 바탕으로 진행되었고, 이는 이해당사자와 정책결정자간의 갈등을 유발했다. 이로 인한 피해를 방지하기 위해 본 연구에서는 참여형(bottom-up) 의사결정 과정 중 하나인 비전공유계획을 충청남도 기후변화 적응 물관리정책 협의회를 통해 적용하였다. 또한, 비전공유계획의 핵심 요소인 비전공유모형을 시스템 다이내믹스 모형의 특성을 포함하여 개발하고자 STELLA Architect 소프트웨어로 보령댐 및 8개 지자체를 포함한 저수지 운영모형을 구축하였고, 총 3차례의 소위원회를 거쳐 수렴한 이해당사자의 요구사항에 따라 개발한 모형을 보완하였다. 구축한 모형으로는 미래에 발생 가능한 가뭄의 위험을 포함하고 있는 기후변화 시나리오에 대한 모의를 진행하였고, 보령댐과 보령댐으로부터 용수를 공급받는 충청남도 서해수역 지자체의 가뭄으로 인한 취약성을 평균부족횟수, 평균부족기간, 평균부족량으로 표현하였다. 모의 결과, 보령댐은 8개 지자체보다 가뭄에 상대적으로 더 취약하며, 8개 지자체에서는 가뭄 대응 대책이 주로 계획되어 있는 지역과 모의에서 가뭄이 발생하는 지역의 불일치로 인한 피해가 발생할 수 있음을 확인하였다. 또한, 다른 평가지표에 비해 예측하기 어려운 평균회복기간에 대해서는 댐과 지자체에서 이를 고려하는 것이 필요하다. 비전공유모형을 통한 가뭄 취약성 분석 결과를 미래 회의에서 이해당사자와 공유하고, 용수 공급처과 수요처의 입장에서 용수 부족을 해소할 방안을 모형에 적용함으로써 미래 가뭄 대응 정책 수립 과정에는 참여형으로 의사결정을 할 수 있음을 제안하였다.

This study aims at predicting and mapping of the landslide susceptibility in the Geumho river watershed using GIS and Remote Sensing techniques. We constructed the spatial database of affecting factors such as slope angle, slope aspect, lithology, landuse, and vegetation index (NDVI) at a $30m{\times}30m$ resolution. The landslide susceptibility of the study area was predicted through overlay analysis and adding up estimation matrix, and the predicted map of landslide susceptibility with six categories (stable, very low, low, moderate, high, very high) was constructed. As the results, it showed that the very high susceptibility zones made up approximately 0.3% of the total study area, and these zones were mainly distributed in the forest area with the high slope angle and low vegetation index.

In this paper, the assessment items were selected for water by drought, water quality by drought, and thermal diseases by heat wave. We described the selection background for these assessment items. and then we weighted the selected vulnerability assessment items. The vulnerability assessment procedures also describe the calculation methods applied in phases and the actual cases. The vulnerability assessment database was analyzed and a climate change vulnerability assessment system for heat waves and droughts using these vulnerability assessment procedures was designed.

KMA(Korea Meteorological Administration) projected that annual mean temperatures of South Korea will rise $3.8^{\circ}C$ and the annual total precipitation will increase by 17 percent by 2100. Rainfall is concentrated during the summer in South Korea. Thus the risk of landslide by heavy rain is expected to increase. After the landslide of Mt. Umyeon occurred in July 2011, disaster of forest sector is highlighted. Therefore vulnerability assessment of landslide is urgent. However, vulnerability assessment based on local governments was not done yet. In this study, we assess vulnerability of landslide by heavy rain for local governments. We used several scenarios to consider uncertainty of climate change. Through this study, local governments can use the results to establish adaptation plans. Also, the results could be used to decrease vulnerability of landslide.

Recently, as part of the crime prevention measures that focus on spatial characteristics on the determinants of crime-causing, interest in crime prevention (CPTED) through environmental design has been increasing. This study analyzed crime vulnerabilities in Ulju-gun for the purpose of establishing a master plan for crime prevention urban design (CPTED). The 12 indicators, including demographic, socioeconomic, and physical factors, were sampled from prior studies. As a next step, statistical analysis resulted in criminal vulnerability indexes. According to the analysis, districts with a high demographic crime vulnerability indexes were concentrated on apartment complexes, while districts with high socio-economic crime vulnerability indexes have low land prices and high proportion of female population. Also, the districts with high physical crime vulnerability indexes were found to be heavily distributed commercial ones with a large number of entertainment places. However, there was a limit to generalizing the indicators of previous studies to local governments with different regional characteristics. Therefore, further studies should be carried out by establishing additional indicators considering regional characteristics in the future.

The purpose of this study is to improve the previous groundwater contamination vulnerability assessment method, apply it to the study area, and select priority areas for groundwater management based on the quantitative analysis of groundwater contamination vulnerability. For this purpose, first, the previous 'potential contamination' based on groundwater contamination vulnerability assessment method was upgraded to the methodology considering 'adaptation capacity' which reduced contamination. Second, the weight of groundwater contamination vulnerability assessment factors was calculated based on the analytical hierarchy process(AHP) and the result of survey targeting groundwater experts. Third, Gyeonggi-do was selected as the study area and the improved methodology and weight were implemented with GIS and actual groundwater contamination vulnerability assessment was carried out. Fourth, the priority area for groundwater contamination management was selected based on the quantitative groundwater contamination vulnerability assessment diagram. The improved detailed groundwater contamination vulnerability assessment factors in this study were a total of 15 factors, and 15 factors were analyzed as new and improved weight with higher 'adaptation capacity' than the assessment factor corresponding to the previous 'potential contamination' in the weight calculation result using AHP. Also, the result of groundwater contamination vulnerability assessment in Gyeonggi Province using GIS showed that Goyang and Gwangmyeong which were adjacent to Seoul had a high groundwater contamination vulnerability and Pocheon and Yangpyeong County had a relatively low groundwater contamination vulnerability. In this study, the previous groundwater contamination vulnerability assessment was improved and applied to study areas actually. The result of this study can be utilized both directly and indirectly for the groundwater management master plan at national and local government level in the future.

Average cumulative precipitation in summer have increased by 350 mm compared with 1980s. As precipitation is expected to increase, the risk of landslides by heavy rainfall also is expected to rise. Therefore, establishment of adaptation plan for landslides is urgently needed. In 2011, Korea Ministry of Environment(KME) conducted vulnerability assessment to support establishment of adaptation plan for local governments. However, the result of vulnerability assessment had three limitations. First, KME didn't use standard scenario of Korea Meteorological Administration(KMA). Second, They conducted same standardization method for all variables. Third, They derived relative vulnerability which is not quantitative. The purpose of this study is to improve the limitations of existing vulnerability assessment and identify quantitative criteria to ensure scientific reliability. To achieve this purpose, we carried out three ways of advancement. First, application of new climate scenario, which is RCP 8.5 from KMA. Second, improvement of variables of vulnerability assessment. Third, derivation of quantitative criteria of vulnerability. The findings can support establishment of adaptation plan for local governments more effectively.
