국제기후변화협약 및 정부의 저탄소 정책은 기본적으로 과학이 제시한 이산화탄소 증가에 대한 기후민감도에 근거해야 한다. 그러나 기후민감도의 추정치는 현재까지 연구 단위별로 차이가 커서, 이에 대한 과학적 배경, 한계, 전망을 고찰할 필요가 있다. 본 연구에서는 지금까지의 기후민감도에 대한 국내외 연구 결과를 객관적으로 종합하여 검토한다. 기후민감도를 결정하는 것은 대기와 지면의 각종 물리과정에 의한 기후피드백 작용이며, 이 중 특히 태양 단파복사량을 조절하는 구름, 해빙과 관련된 물리과정은 불확실성이 가장 커서, 부정확한 민감도 추정을 야기하는 것으로 보인다. 이 때문에, 최근 인공위성 자료를 이용하여 추정한 기후민감도는 기후모델들이 갖는 범위(대기 중 이산화탄소 2배 증가당 지구평균기온 2-5 K 증가)에 들거나, 그보다 훨씬 작은 값을 갖는다.

While global warming and climate change have been issues with global implications for ecology and nature as well as for the economy, politics and social sector, Korean's climate change awareness has been reported to be low. This phenomenon can be attributed to the fact that there is neither a systematic and continuous educational program for climate change nor a system to implement and support it. Although environmental education traditionally has not been a center of focus in most schools, the move towards "green growth" in national policies are slowly influencing school education as well. Throughout the year 2009, Green Suncheon 21 has offered a program called 'Suncheon Climate School' designed for elementary schools and regional centers for underprivileged children. Program instructors were sent to schools and centers that requested such climate change education. The aim of this study is to evaluate the success of the program and to provide feedback on its impacts. According to the study, students' interests in climate change have increased after the climate change education, and students found the lectures to be informative and interesting. Students said that they became more aware of the serious consequences of global warming and climate change and found that such education is beneficial and should be available to a wider population. This study suggests that first, school teachers should be aware of climate change and support such educational programs to be a part of the regular curriculum. Second, the content and the level of the program should be designed in consideration of the corresponding school curriculum to make the subject relevant and accessible to students.

기후변화 정책 분석 모델 (PAGE, Policy Analysis of Greenhouse Effect)을 이용해 여러 온실가스 배출 시나리오에 따른 기후변화의 피해 비용을 분석했다. 국내외 기후변화 영향에 관한 선행 연구 결과에 따르면 한국의 기후변화의 민감도는 경제 협력개발기구(OECD) 회원국들과 유사한 수준이 될 것으로 전망되었으나 구체적인 한국의 분야별 영향평가가 이루어져야 보다 정량적인 기후변화의 피해함수 추정이 가능할 것이다. 온실가스 배출량, 이산화황 배출량, 적응정책의 정도, 경제 성장, 인구 성장 등 많은 인자들이 기후변화로 인한 피해 정도에 영향을 미친다. 본 연구에서는 PAGE 모델을 이용해 미래의 여러 상황에 따른 기후변화의 피해 정도를 알아보기 위하여 A2, B1, Kyoto, 3가지 시나리오에 대한 분석을 하였다. 만일 전 세계가 온실가스 감축을 위한 아무 대책도 실행하지 않는다면 2100년 한국은 약 3도 정도의 온도상승이 예측되고 이로 인해 12조에서 58조정도의 피해가 일어날 것으로 분석되었다. 1990년에서 2100년까지 기후변화로 인한 누적 피해비용은 약 143조에서 921조에 이를 것으로 분석되었다.그러나 이는 소수의 피해함수에 대한 연구결과만을 반영해 산정한 결과며 분야별로 더 많은 연구가 수행되어야 보다 신뢰도 높은 피해비용을 산정할 수 있다.

This research aims at analyzing impacts of climate change on fisheries. Climate change is an additional pressure on top of the many which fish stocks already experience. This implies that the impact of climate change must be evaluated in the context of other anthropogenic pressures, which often have a much greater and more immediate effect. Conversely, it is evident that fish stocks will be more resilient to climate impacts if the stresses due to other factors, such as over-fishing and pollution, are minimized. Improved management of fisheries and of marine ecosystems can undoubtedly play an important role in adapting to the impacts of climate change. Most of the improvements which are needed do not require new science or understanding, they require patient development of acceptable, effective, responsive social institutions and instruments for achieving adaptive management. Management advices must include complete and transparent information on risks and uncertainties which arise from data quality and from structural deficiencies in the assessment models. Well-designed and reliable monitoring of fish stocks and the marine ecosystem is essential in order to detect changes and give warning in advance of alterations in the productivity of individual species and of the structure and functioning of the ecosystem and fishery economy on which they depend.

Since the terrain of Korea is complex, micro- as well as meso-climate variability is extreme by locations in Korea. In particular, air temperature of agricultural fields is influenced by topographic features of the surroundings making accurate interpolation of regional meteorological data from point-measured data. This study was carried out to compare spatial interpolation methods to estimate air temperature in agricultural fields surrounded by rugged terrains in South Korea. Four spatial interpolation methods including Inverse Distance Weighting (IDW), Spline, Ordinary Kriging (with the temperature lapse rate) and Cokriging were tested to estimate monthly air temperature of unobserved stations. Monthly measured data sets (minimum and maximum air temperature) from 588 automatic weather system(AWS) locations in South Korea were used to generate the gridded air temperature surface. As the result, temperature lapse rate improved accuracy of all of interpolation methods, especially, spline showed the lowest RMSE of spatial interpolation methods in both maximum and minimum air temperature estimation.

The improvement of the performance of savings and loan cooperatives in Indonesia is a challenge in the digital era. The purpose of this research is to find how big the role of psychological climate is in mediating the relationship between leadership and organizational commitment. This study hopes to confirm the influence of leadership and psychological climate on organizational commitment and examines the psychological climate intervention (mediation) on the relationship between leadership and organizational commitment of the cooperatives. The population of this research is all members of the cooperative in Bali. This study uses a saturated sampling method to determine the sample. Data collection was carried out through questionnaires and data analysis using PLS. The results showed that in the digital era, leadership has a positive effect on organizational commitment, psychological climate, and in the end, will provide positive organizational commitment. Psychological Climate mediation answers the question that the impact of leadership and commitment will continue to exist and perform in an era of disruption. Culture is important in an organization; some areas such as Bali have a thick local culture. Perhaps future research should be improved on local culture and leadership transformation.

The purpose of this paper is to investigate the influence of ethical leadership in determining the organizations' individual-type ethical climate (self-interest, friendship, and personal morality ethical climate) in reducing employee turnover intention. It seeks to identify the role of individual-type climate in mediating the association between ethical leadership and employee turnover intention. Moreover, the moderation effect of emotional exhaustion among employees on the relationship between ethical leadership and turnover intention has been researched to establish the ethical degree of leadership. Using a sample of 260 questionnaires from employees working full-time in the banking sector, the results were analyzed in PLS-SEM. The results of the social exchange theory indicated that ethical leadership is vital in shaping the workplace's individual-type ethical climate and reducing employees' turnover intention. The findings demonstrate that the relationship between ethical leadership and turnover intention is mediated by an individual-type ethical climate, which means that employees in a positive ethical climate do not wish to leave immediately. Furthermore, emotional exhaustion was found to moderate the association between ethical leadership and employees' turnover intention under high emotional exhaustion, where low ethical leadership is experienced, reporting higher levels of turnover intention.

Climate crisis is one of the most urgent and serious threats to the right to life. As AR picture books are particularly effective for safety education, this study aimed to produce an AR picture book featuring animals that are endangered due to the climate crisis. In order to increase the educational effect and enhance the climate sensitivity, this study developed a children's activity workbook (with follow-up activities) and a teacher's guide (with lesson plans) as a package. To this end, market research and surveys were first conducted. Next, through the management and support of the Korea Institute of Startup & Entrepreneurship Development, this research team produced a climate crisis themed AR picture book package through expert advice, help from outsourcing companies, and field application. The package was promoted through publicity in various forms of media. The contents of the AR-using picture book package of this case study were introduced and then advantages and disadvantages were discussed.

기후 변화는 21세기에 인류가 맞이한 가장 중요한 문제 중에 하나이다. 탄소 배출은 이러한 기후 변화의 가장 핵심 원인으로 지목 된다. 토양은 관리 방법에 따라서 탄소의 저장원이 되기도 하지만 큰 배출원이 될 수도 있다. 기온의 변화는 농경지 토양에서 배출되는 온실가스의 양을 크게 변화시킬 수 있을 뿐만 아니라 작물의 생산량을 위한 농법 변화에도 영향을 미치기 때문에 기후 변화에 따른 온실가스 배출 변화는 두 가지 요인의 상호작용을 고려할 필요가 있다. 본 연구에서는 남한의 논에서의 온실가스 배출은 2011년부터 2100년까지 RCP 8.5 시나리오의 기상 변화에 따라서 모의하였다. 농법의 변화로는 다양한 논의 담수 기법이 적용되었다. 기존의 담수 기법으로는 기후변화가 진행됨에 따라서 온실가스 배출이 급격하게 상승하는 것을 확인할 수 있었고, 간단관수가 이러한 온실가스 배출을 크게 감소시킴을 확인하였다. 미래의 농법이 작물의 생산량을 최대화시키는 방향으로 변화한다고 가정하였을 때 기후 변화에 따라서 많은 농지가 관행 농법 보다 간단관수가 시행되었을 때 수확량이 상승하게 되었고, 이러한 기후변화의 적응을 고려하였을 때는 기후 변화에 따라서 온실가스 배출이 감소함을 확인하였다.
