여름철만 되면 폭염 취약계층의 피해 소식이 꾸준히 발생하고 있다. 본 연구는 폭염 취약계층을 예측하기 위한 방법으로 통신사와 공공데이터에서 유동인구데이터, 전기사용량, 온도데이터, 건물 면적, 병원 접근성 등을 활용하여 분석하였다. 디지털 트윈 기법을 활용해 분석결과 높은 온도대비 면적당 전기사용량이 적으며 동시에 유동인구가 많고 병원 접근성이 떨어질수록 폭염 취약계층일 확률이 높을 것으로 예측하였다.

지구온난화 및 기후상승으로 폭염발생 일수 및 강도가 증가됨에 따라 온열질환으로 인한 인명피해가 꾸준히 증가되고 있다. 온열질환 발생은 폭염일수가 증가할수록 증가됨에 따라 폭염 취약 계층에 대한 피해 대응이 요구되고 있다. 본 연구에서는 폭염 취약 계층을 대상으로 폭염으로 인한 피해를 감소시키고자 온열질환용 웨어러블 디바이스 기반 실시간 활력 징후 데이터 수집 및 분석을 통해, 온열질환 의심환자 이벤트 발생에 대한 신속한 대응이나 여름철 생활지수를 통해 휴식을 권장하도록 지원할 수 있는 온열질환 모니터링 시스템을 제안한다.

In most developed countries, Extreme heat alter system operates every summer and the response plan to be issued according to this system is composed of some government agencies sub-plans. The National Emergency Management Agency in Korea develops response plan but it is not composed of the definition of the heat vulnerability and the concrete agency roles. Therefore, this study analyses foreign cases in three processing: preparedness, response, recovery and reviews the status of heat response plan. As a conclusion, the study suggests two ways of Extreme heat management into Korean heat response plan such as strengthening its institutional position and complementing its context.

Global warming has also increased the number of casualties caused by heat-related diseases caused by heat waves along with an increase in global temperature. The vulnerable groups from heat wave damage are outdoor workers and the elderly in particular, and it is necessary to respond the increasing heat wave damage. We propose a real-time control platform in order to reduce casualties of the vulnerable group from heatwaves, this research collects and analyzes user's vital signs data from wearable devices that generates alarms out of the suspected victims who are expected to be affected by heat-related illness and to respond quickly.

전 세계적으로 기후변화에 대해 민감하게 대응하고 있으며, 이중 국내에서는 지난 2018년 폭염을 자연 재난으로 개정했다. 대구시는 매년 지역 현안의 해결과제로 폭염 재난을 언급하고 있다. 이전 연구를 통해 대구시를 대상으로 온열 질환 취약 계층을 고려한 폭염 대응 관제 플랫폼을 개발했다. 본 연구는 온열 질환 의심 환자 판별알고리즘 및 실시간 모바일 앱 알림 서비스를 추가 적용 등 플랫폼 고도화 작업을 진행했다.

The aim of this research was to develop a climate change vulnerability index at the district level (Si, Gun, Gu) with respect to the health care sector in Korea. The climate change vulnerability index was esimated based on the four major causes of climate-related illnesses : vector, flood, heat waves, and air pollution/allergies. The vulnerability assessment framework consists of six layers, all of which are based on the IPCC vulnerability concepts (exposure, sensitivity, and adaptive capacity) and the pathway of direct and indirect impacts of climate change modulators on health. We collected proxy variables based on the conceptual framework of climate change vulnerability. Data were standardized using the min-max normalization method. We applied the analytic hierarchy process (AHP) weight and aggregated the variables using the non-compensatory multi-criteria approach. To verify the index, sensitivity analysis was conducted by using another aggregation method (geometric transformation method, which was applied to the index of multiple deprivation in the UK) and weight, calculated by the Budget Allocation method. The results showed that it would be possible to identify the vulnerable areas by applying the developed climate change vulnerability assessment index. The climate change vulnerability index could then be used as a valuable tool in setting climate change adaptation policies in the health care sector.

The critical temperature and the rate of increase in excess death caused by heat waves in the age group of 65 years and older are derived. The value of statistical life method was used to quantify economic damages, and the willingness to pay after 71 years of age for 10 years was measured based on the dichotomous choice contingent valuation method survey. The result shows about KRW 481,110,000 is required annually to reduce the possibility of death by climate change to 1/1000.

As the damage caused by the abnormal climate due to climate change is increasing, the interest in resilience is increasing as a countermeasure to this. In this study, the resilience of Suwon city was examined and the plan to improve the resilience were derived against climate impacts such as drought, heatwave, and heavy rain. Urban resilience is divided into social resilience (e.g. vulnerable groups, access to health services, and training of human resources), economic resilience (e.g. housing stability, employment stability, income equality, and economic diversity), urban infrastructure resilience (e.g.residential vulnerability, capacity to accommodate victims, and sewage systems), and ecological resilience (e.g. protection resources, sustainability, and risk exposure). The study evaluated the urban resilience according to the selected indicators in local level. In this study, the planning elements to increase the resilience in the urban dimension were derived and suggested the applicability. To be a resilient city, the concept and value of resilience should be included in urban policy and planning. It is critical to monitor and evaluate the process made by the actions in order to continuously adjust the plans.

In order to resolve the imbalances in the supply of living SOCs according to socio-economic status, location, and population groups, the discussions on inclusive city policies are expanding. The purpose of this study is to propose an Index of Park Derivation (IPD) as an alternative indicator for the promotion of an inclusive urban park policy that can be applied in the 7 major metropolitan cities to select a region with a relatively high park needs. The main research results are as follows. First, the concept of an inclusive urban park policy is defined as "a policy to supply to manage high-quality park services with priority given to areas with low socio-economic and environmental status, such as a large amount of elderly, children, low-income families, areas vulnerable to disasters, such as heat and fine dust, and population groups." Second, we developed the index of park derivation (IPD), which is a combination of 17 variables including park service level, demographic characteristics, economic and educational level, health level, and environmental vulnerability. The variables that constitute the index of park deprivation (IPD) can be applied to SOC policies outside the parks, such as sports facilities, daycare centers, kindergartens, and public libraries. Third, applying index of park deprivation (IPD) to 1,148 Eup/Myeon/dong areas of the 7 metropolitan cities resulted in areas with relatively high park service needs. This study implies that the central and the local government suggest an alternative index to promote an inclusive urban park policy based on statistical and geographical information and data that can be easily accessed and utilized.
