2022년 8월 수도권 이상폭우로 인해 서울 도심지역의 지하시설, 도로, 주택 등에 침수가 발생하면서 인명 및 재산피해가 발생하였으며, 특히 동서로 가로지르는 정체전선으로 좁고 긴 비구름이 집중되면서 국지적으로 피해가 집중되었다. 서울시의 경우 도시화에 따른 불투수지역 증가 및 내수배제 불량에 따른 빗물 역류로 인한 피해가 지속적으로 발생하고 있으며, 최근에는 기후변화에 따른 방재성능목표 강우량을 초과하는 빈도의 이상폭우로 인해 하천범람과 내수배제 불량에 따른 복합적인 원인으로 침수피해 가중되고 있는 실정이다. 또한 서울시의 경우 전체 자연적, 사회적, 경제적, 환경적 요인 등의 지역적 편차가 매우 큰 도시로 지형적인 특성뿐만 아니라 취약시설(병원, 학교 등), 수방시설물(하천, 배수시설, 빗물펌프장 등) 및 방재시설(대피소, 구호소 등) 밀도 등에 따른 침수 취약성 및 위험성 등의 편차가 매우 크기 때문에 지역특성에 대한 피해사례가 다원화 되고 있는 실정이다. 본 연구에서는 30년 이상의 종관기상관측(ASOS)과 서울시 자치구별 20년 이상의 방재기상관측(AWS)자료를 기반으로 CMIP6 SSP(Shared Socioeconomic Pathways, 공통사회 경제경로)시나리오에 따른 극한기후 지수(강수강도, 호우일수, 지속기간, 1일 최대강수량, 95퍼센타일 강수일수 등)에 대한 재현성을 평가하고 공간자기상관분석 등 시공간적인 강우특성에 대한 변화를 전망하였다. 특히 여름철 강우의 경우 자치구별 편차가 크게 나타났고 이를 통해 대도시의 도심지역의 경우 세분화하여 지역의 정확한 강우특성을 파악하는 것이 필요하다는 것을 확인할 수 있었다. 본 연구의 결과는 도심지의 방재성능 초과강우 정의와 기준을 수립하고, 장기적인 수자원 및 도시계획 차원의 대책을 마련하는데 활용될 수 있을 것으로 판단된다. 기후위기에 따른 기록적인 호우(지역별 방재성능을 초과하는 강우)에 따른 재해는 구조적인 대책을 통해 모두 저감할 수 없는 한계가 있다. 하지만 인명피해를 최소화하는 것을 목표로 기후위기에 대한 적응단계로 인식하고 수리·수문학적, 사회경제학적 등 지역특성에 따른 방재성능목표 강우량에 대한 재검토와 더불어 법제도(풍수해보험, 저류조설치 의무화 등), 개인별 재해예방, 취약계층 안전망 확보, 반지하주택 침수안전대책, 재해지도 개선 등 구조적/비구조적인 대책을 통합 수립 및 보완하는 것이 필요한 시점이다.

This paper is aimed to recognize trends of various social groups about multiple transportation policies such as the crosswalk restoration by eliminating the pedestrian overpasses and the improvement or continuous extension of existing pedestrian overpasses, currently implemented in Busan, following the globally prevailing pedestrian-oriented transportation environment. Also, this paper utilizes Contingent Valuation Method (CVM) to evaluate the efficiency of individual alternatives in terms of respondent's willingness-to-pay (WTP). Consequently, survey participants preferred the crosswalk or improvement of the pedestrian overpasses rather than depending on the existing pedestrian overpasses. In addition, the WTP value for the crosswalk restoration is approximately 42,452 won per household per year, and, on the other hand, the WTP value for the improvement of existing pedestrian overpasses is approximately 36,793 won per household per year, implicating that the transportation policy makers are suggested to place more priorities on crosswalk restoration than the improvement of the existing pedestrian overpasses.

This study aims to analyse the process of digital switchover in the UK, which is regarded as one of the most successful cases in the world, and to examine efficient plans for the future digital switchover project in Korea through the UK's case. The digital switchover in the UK shows with no doubt the significance of integrated government policies, collaboration between relevant governmental organisations, and the public service broadcaster. Along with this, active and detailed Public Relations (PR) should take place, helping the citizens realise the efficiency of the phased switchover region by region and the measures to resolve the gaps between all social brackets. To sum up, the successful digital transfer is not only achieved by governmental policy and technological preparation from broadcasters, but also by voluntary citizen participation. Government officers and broadcast executives need to realise this and should focus on communicating with citizens.

Structural flood defensive alternatives have been evaluated based on economic feasibility, riskiness of safety and sustainability. Social problems associated with structural flood defensive alternatives such as dams, flood control channels, etc. are currently issued. The evaluation items of policy presented in KDI(2001) are should be modified in order to resolve the social problems. Hence, this study conducted a questionnaire survey of public servants, researchers, and engineers to obtain how to determine evaluation items for policy assessment and to compute their weights in the analytic hierarchy process. This study also compared the weights of the items in KDI(2000) with the weights from the survey in this study. The policy assessment weight was estimated higher than KDI(2000). This result suggests that social awareness increases and the analysis of policy becomes important for selecting optimal structural defensive alternatives.
