In recent years, the most safety studies have been focused on identifying the relationship between safety climate and safe work behavior in accordance with the awareness that prime causes of accidents are organizational, managerial, and human factors rather than pure technical failures across the world. This study focused empirical research aimed at finding out the safety climate factors and examining the relationships of the safety climate and safe work behavior in construction site in Korea, too. A 10 numbers of safety climate factors were adapted from the Mohamed's study(2002) and tested using PLS-GRAPH 3.0 expecting same results as Mohamed' study. And then the relationship between safety climate and safe work behavior was examined. Only two safety climate factors-personal risk appreciation and worker's safety competence-were found and a strong positive relationship between safety climate and safe work behavior was identified in this study. Discussed in details about the results and implications and suggested further studies.

In the context of the Ministry of Environment's 2022 Climate Change Adaptation Plan for Public Institutions, public sewage treatment plants are one of the important targets for climate change response aimed at sustainable water management. In this study, it is applied a modified methodology to four water regeneration centers (public sewage treatment facilities) in charge of sewage treatment in Seoul to analyze the impacts and risks of climate change and discuss priorities for adaptation measures. The results of the study showed that heavy rains, heat waves, and droughts will be the key impacts of climate change, and highlighted the need for measures to mitigate these risks, especially for facility managers.

최근 우리나라는 기후변화 영향으로 극심한 가뭄으로 인한 피해가 발생하고 있다. 따라서 가뭄에 대한 완화대책을 마련하기 위해서는 가뭄 위험도의 변화를 분석할 필요가 있다. 본 연구에서는 관측 강수량 자료와 RCP 4.5 및 8.5 기후변화 시나리오에 따른 미래 강수량 자료를 활용하여 극한가뭄에 대한 수문학적 위험도를 평가하였다. 먼저, 임계수준방법으로 가뭄사상을 정의하고 풀링을 통하여 미소가뭄을 제거하여 도출한 가뭄 지속기간 및 심도를 대상으로 이변량 가뭄빈도분석을 실시하였다. 극한가뭄사상에 대한 수문학적 위험도를 산정한 결과, RCP 4.5 시나리오에서 위험도가 가장 높은 지역은 전라북도이며 과거보다 51 % 증가하였다. 또한, RCP 8.5 시나리오에서 위험도가 가장 높은 지역은 강원도이며 과거보다 47 % 증가하였다.

본 연구는 겨울철 휴면심도와 동해유발온도를 기반으로 작성된 복숭아 나무 '장호원황도' 품종의 휴면지에 대한 동해위험지수 계산식을 고해상도 전자기후도와 결합하여 현재평년(1971-2000년)의 기후조건에서 동해위험의 지역적 분포를 파악하였다. 이를 기준으로 두고 기후변화 시나리오에 근거한 미래 3개 평년(2011-2040년, 2041-2070년, 2071-2100년)의 기온자료에 동일한 방법을 적용하여 얻은 동해위험지수와 비교함으로써 기후변화에 따른 이들 위험지역의 이동을 경관규모에서 추적하였다. 현재평년(1971-2000년) 기후조건에서는 전 국토의 4%가 안전지대, 88%가 동해 위험 경계지대, 8%가 위험지대로 탐색되었다. 시나리오 기후조건에서는 가까운 미래(2011-2040년)와 먼 미래(2041-2100년)에 모두 경계지대가 줄어드는 반면 안전지대와 위험지대가 다같이 증가하였다. 이 방법은 경기도 이천, 경북 청도 등 복숭아 주산지 내의 위험지대를 경관규모에서 탐색하는 데도 이용될 수 있음이 확인되었으므로 앞으로 농업분야 기후변화 영향평가 및 취약성 분석에 기여할 것으로 기대된다.

In order to assess risk of high temperature damages about corn during reproduction stages in the future, we carried out analysis of climate change scenarios RCP (Representative Concentration Pathway) 4.5 and RCP8.5 distributed by KMA (Korea Meteorological Administration) in 2012. We established two indexes such as average of annual risk days of high temperature damage which express frequency and strengthen index of high temperature damage. As results of producing maps for 157 cities and counties about average of annual risk days of high temperature damage during total periods of scenarios, the risk of high temperature in RCP8.5 was evaluated to increase at all over nation except inland area of Gangwon province, while RCP4.5 showed similar to present, or little higher. The maps of annual risk days of high temperature damage with 10 years interval in RCP8.5 prospected that the risk for damaging corn growth would increase rapidly from 2030's. The largest risk of high temperature damage in the future of RCP8.5 was analyzed at Changnyeong county located east-south inland area in Kyeongnam province, while the smallest of risk counties were Pyeongchang, Taebaek, Inje, and Jeongseon. The prospect at 12 counties which is large to produce corn at present and contains large plains have been showed that there will be only a little increase of risk of high temperature at Goesan, Yangpyeong, Hongcheon, Seosan, and Mooju until 2060's. But considering strengthen index of high temperature damage, most regions analyzed would be prospected to increase rapidly after 2030's. To cope with high temperature damage of corn in the future, we should develop various practical technologies including breeding adapted varieties and controlling cultivation periods.

Flooding events often result from extreme precipitations driven by various climate mechanisms, which are often disregarded in flood risk assessments. To bridge this gap, we propose a climate-mechanism-based flood frequency analysis that accommodates the direct linkage between the dominant climate processes and risk management decisions. Several statistical methods have been utilized in this approach including the Markov Chain analysis, K-nearest neighbor (KNN) resampling approach, and Z-score-based jittering method. After that, the impacts of climate change are associated with the modification of the transition matrix (TM) and the application of the quantile mapping approach. For this study, we have selected the Nam River Basin, South Korea, to consider the heterogeneous impacts of the two climate mechanisms, including the Tropical Cyclone (TC) and non-TCs. Based on our results, while both climate mechanisms have significant impacts on future flood extremes, TCs have been observed to bring more significant and immediate impacts on the flood extremes. The results in this study have proven that the proposed approach can lead to a new insights into future flooding management.

Severe wind is one of the major natural hazards in Australia. The component contributors to economic loss in Australia with regards to severe wind are tropical cyclones, thunderstorms and subtropical (synoptic) storms. Geoscience Australia's Risk and Impact Analysis Group (RIAG) is developing mathematical models to study a number of natural hazards including wind hazard. This paper discusses wind hazard under current and future climate conditions using RIAG's synoptic wind hazard model. This model can be used in non-cyclonic regions of Australia (Region A in the Australian-New Zealand Wind Loading Standard; AS/NZS 1170.2:2011) where the wind hazard is dominated by synoptic and thunderstorm gust winds.

Objectives: The mass media play a crucial role in risk communication regarding climate change. The aim of this study was to investigate the trend in journalistic reports on climate change in the daily newspapers of Korea. Methods: We selected 9 daily newspapers in Korea, which according to the ABC Association, represented 77% of newspaper circulation, out of a total of 44 Korean daily newspapers. The collected articles were from 2009 to 2011. All of the articles were sorted into the following 8 categories: greenhouse gas, climate change conventions, sea level rise, Intergovernmental Panel on Climate Change synthesis reports, expected damage and effect, use of fossil fuels, global warming, and mitigation or adaptation. A chi-squared test was done on the articles, which were counted and classified into cause, effect, and measurement of climate change according to the newspaper's majority or minority ownership structure. Results: From the 9 selected newspapers, the number of articles on climate change by month was greatest in December 2009. Generally, the articles vague about climate change (lack of precise data, negative or skeptical tone, and improper use of terminology) were much more common than the articles presenting accurate knowledge. A statistical difference was found based on ownership structure: the majority-owned newspapers addressed the cause of climate change, while the minority-owned newspapers referred more to climate change measurement. Conclusions: Our investigation revealed that generally Korean daily newspapers did not deliver accurate information about climate change. The coverage of the newspapers showed significant differences according to the ownership structure.
