Recently, occurrence frequency of natural disaster decrease but scale of damage increase remarkably by the Climate change due to global warming. Especially, extreme heat become more critical wether problem in the Korean Peninsula. But, we don't have exact threshold about extreme heat. Therefore, to assess the influences by the extreme heat on personal injury, we analyzed statistics on the causes of the daily mortality. And we developed a threshold for extreme heat health watch warning system.

기후변화는 미래세대의 문제뿐만 아니라 현재를 살고 있는 우리들에게도 매우 심각한 화두가 되고 있다. 또한 OECD 환경전망 2050 보고서를 비롯한 많은 연구에서 온실가스 증가로 인한 지구 평균기온 상승을 경고하고 있다. 평균기온 상승은 강우패턴의 변화를 일으켜 극한기후상황인 가뭄, 폭염, 홍수 등의 증가로 이어지며, 많은 피해가 예상된다. 우리나라 연평균기온은 1981년~2010년 1.2℃ 상승 했으며, RCP8.5 시나리오에서는 2100년경 4.7℃ 증가하는 것으로 전망된다. 이로 인해 열대야일수, 폭염일수, 여름일수와 같은 극한지수가 증가하고 강수량 변동이 매우 클 것으로 예상되며, 가뭄관련 최대무강수 지속기간도 길어지며, 극심한 물부족이 예상된다. 따라서 가뭄 재해를 대비하고, 지하수의 활용에 대한 계획 수립에 바탕이 되는 연구가 필요하다. 본 연구에서는 기후변화에 의한 가뭄기간 동안의 지하수위 변동 특성을 예측하고자 한다. 기후변화 예측은 IPCC 대표농도경로 RCP2.6, RCP4.5, RCP6.0, RCP8.5 시나리오에 의한 기상청의 미래 기후전망 프로그램을 활용하여 경주지역의 2021년~2100년 까지의 평균기온, 강수량을 분석하였다. 연구대상 유역의 도시개발계획을 조사하고 장래 토지피복도를 추정하여 SWAT모형에 적용하여 지하수 함양에 영향을 미칠 수 있는 인자들에 대한 보정 및 모델링을 실시하여 장래 기후변화에 의한 지하수 함양량을 추정하였다.

In this study, the effect of extreme heat diet on growth performance, lymphoid organ, blood immunoglobulin and cecum microflora change in broilers exposed to continuous lighting and extreme heat stress (EHS) was studied. Broilers raised under normal environment temperature ($25^{\circ}C$ or extreme heat stress temperature ($33{\pm}2^{\circ}C$, and consumed chow diet (CD) or extreme heat stress diet (EHSD). Five hundred Ross 308 day-old commercial broilers were arranged in a completely randomized block design of 5 treatment groups with 4 repetitions (25 heads per repetition pen). The broilers were divided into: T1 (normal environment+CD), T2 (EHS+CD), T3 (EHS+EHSD in which the tallow in CD was substituted by soy oil and contained 5% molasses), T4 (EHS+EHSD in which the tallow in CD was substituted by soy oil and contained 5% molasses, and 1.5 times more methionine and lysine than CD), and T5 (EHS+EHSD in which the tallow in CD was substituted by soy oil, contained 5% molasses, 1.5 times more methionine and lysine than CD, and 300ppm of vitamin C). The EHS significantly reduced the body weight gain and feed intake. The blood immunoglobulin, bursa of Fabricius, thymus, and spleen weight were significantly reduced when broilers were exposed to EHS. Compared to the normal environment temperature group, the cecum Lactobacillus sp. was low in the EHS treatment group, while Escherichia sp., Salmonella sp. and total aerobic bacteria in the EHS treatment group were high. A statistically significant difference was acknowledged between the treatment groups.

This study uses geo-spatial crop modeling to quantify the biophysical impact of weather extremes. More specifically, the study analyzes the weather extreme which affected maize production in the USA in 2012; it also estimates the effect of a similar weather extreme in 2050, using future climate scenarios. The secondary impact of the weather extreme on food security in the developing world is also assessed using trend analysis. Many studies have reported on the significant reduction in maize production in the USA due to the extreme weather event (combined heat wave and drought) that occurred in 2012. However, most of these studies focused on yield and did not assess the potential effect of weather extremes on food prices and security. The overall goal of this study was to use geo-spatial crop modeling and trend analysis to quantify the impact of weather extremes on both yield and, followed food security in the developing world. We used historical weather data for severe extreme events that have occurred in the USA. The data were obtained from the National Climatic Data Center (NCDC) of the National Oceanic and Atmospheric Administration (NOAA). In addition we used five climate scenarios: the baseline climate which is typical of the late 20th century (2000s) and four future climate scenarios which involve a combination of two emission scenarios (A1B and B1) and two global circulation models (CSIRO-Mk3.0 and MIROC 3.2). DSSAT 4.5 was combined with GRASS GIS for geo-spatial crop modeling. Simulated maize grain yield across all affected regions in the USA indicates that average grain yield across the USA Corn Belt would decrease by 29% when the weather extremes occur using the baseline climate. If the weather extreme were to occur under the A1B emission scenario in the 2050s, average grain yields would decrease by 38% and 57%, under the CSIRO-Mk3.0 and MIROC 3.2 global climate models, respectively. The weather extremes that occurred in the USA in 2012 resulted in a sharp increase in the world maize price. In addition, it likely played a role in the reduction in world maize consumption and trade in 2012/13, compared to 2011/12. The most vulnerable countries to the weather extremes are poor countries with high maize import dependency ratios including those countries in the Caribbean, northern Africa and western Asia. Other vulnerable countries include low-income countries with low import dependency ratios but which cannot afford highly-priced maize. The study also highlighted the pathways through which a weather extreme would affect food security, were it to occur in 2050 under climate change. Some of the policies which could help vulnerable countries counter the negative effects of weather extremes consist of social protection and safety net programs. Medium- to long-term adaptation strategies include increasing world food reserves to a level where they can be used to cover the production losses brought by weather extremes.

As abnormal climates occur due to the increase in greenhouse gases at home and abroad, various problems such as human casualties, crop damage, energy depletion, and economic loss due to heat diseases, which are one of the extreme climate phenomena, are following one after another. In response, the government has established the 'Climate Crisis Response Special Committee' since 2018, when it recorded the greatest damage in history due to heat waves, and has been carrying out budget formation and reform of laws and systems every year to respond to heat waves. However, in relation to the heat wave damage reduction facility that is being expanded with a large budget, there is no prior research related to the degree of heat loss due to the use of the facility, the difference in effects between specific groups, and the economic effect that comes back compared to the invested budget. Therefore, from a midto long-term perspective, it is expected that it will be difficult to establish a clear direction for policy making. Therefore, in this study, representative facilities were selected according to the principle of heat reduction among the currently expanded heat damage reduction facilities, and a questionnaire survey was conducted for users of each reduction facility (waterfall, awning, pond, and elastic pavement). Accordingly, the change in the sense of heat according to the use of the heat damage reduction facility was checked, and the change in the sense of heat according to the group characteristics (gender, age, metabolic rate) was analyzed to examine the characteristics of the relationship between the facility and the users.
