Global warming affects forests and their ecology. Diversity in the forest is a buffer that reduces the damage due to global warming. Mixed forests are ecologically more valuable as versatile habitats and are effective in preventing landslides. In Korea, most forests were created by simple afforestation with trees of evergreen species. Typically, evergreen trees are shallow-rooted, and deciduous trees are deep-rooted. Mixed forest tree roots grip the soil effectively, which reduces the occurrence of landslides. Therefore, improving the distribution of tree types is essential to reduce damage due to global warming. For this improvement, the investigation of tree types of the forest is needed. However, determining the tree type distribution of forests that are spread over wide areas is labor-intensive and time-consuming. This study suggests effective methods for determining the distribution of tree types in a forest that is spread across a relatively wide area. Using normalized difference vegetation index and RGB images from unmanned aerial vehicles, each evergreen and deciduous tree, and grassland area can be distinguished. The distinguished image determines the distribution of tree type. This method is effective compared to directly determining the tree type distribution in the forest by the use of manpower. The data from these methods could be applied to plan a mixed forest or to prepare for future damage due to global warming.

Extreme temperatures and precipitations are expected to be more frequently occurring due to the ongoing global warming over the Korean Peninsula. However, few studies have analyzed the synoptic weather patterns associated with extreme events in a warming world. Here, the atmospheric patterns related to future extreme events are first analyzed using the HadGEM3-RA regional climate model. Simulations showed that the variability of temperature and precipitation will increase in the future (2051-2100) compared to the present (1981-2005), accompanying the more frequent occurrence of extreme events. Warm advection from East China and lower latitudes, a stagnant anticyclone, and local foehn wind are responsible for the extreme temperature (daily T>$38^{\circ}C$) episodes in Korea. The extreme precipitation cases (>$500mm\;day^{-1}$) were mainly caused by mid-latitude cyclones approaching the Korean Peninsula, along with the enhanced Changma front by supplying water vapor into the East China Sea. These future synoptic-scale features are similar to those of present extreme events. Therefore, our results suggest that, in order to accurately understand future extreme events, we should consider not only the effects of anthropogenic greenhouse gases or aerosol increases, but also small-scale topographic conditions and the internal variations of climate systems.

본 연구는 지구과학교육을 전공하는 예비교사들에게 SDGs(지속가능발전목표)와 연계된 ESD(지속가능발전교육)을 적용하기 위한 기초 연구이다. 연구의 목적은 예비교사가 내면화 하고 있는 탄소발자국에 대한 인식과 태도 및 지식, 주관적 규범 및 행동 통제를 분석하여 탄소 소양을 평가하는 것이다. 예비교사들은 탄소 발자국을 자신의 책임으로 인식하고 있지만, 비용을 지불하고 불편을 감수하는데 소극적인 이중적 태도를 갖고 있다. 또한 탄소 발자국을 줄이기 위한 행동을 지지하지만, 요구하지는 않는다. 탄소 저감 행동에 대한 상식은 충분한 반면, 지구 온난화의 원인과 결과에 대한 개념은 불안정하다. 예비교사들은 학교 현장으로 배출되어 수많은 학생들에게 지구 온난화 문제를 가르치게 될 것이다. 따라서 탄소 발자국을 줄이는 경제적 비용과 사회적 책임에 대한 소양 교육이 필수적이며, 생각과 행동 사이의 간극을 메울 수 있는 방법을 찾아야 할 것이다. 예비교사들의 탄소 소양(carbon literacy)에 대한 연구로부터 ESD로 이어지는 교육이 실현되기를 바란다.

Facing the issue of global climate change, it is important for environmental educators to prepare a person who is able to understand of, communicate about, and make informed decisions on the climate change. Climate change education is to help learners understand of human influence on climate and climate's influence on them and society. This study was conducted in a way to discuss how climate change education could be implemented in Korean context. For this purpose, several documents and research articles on climate change education and communication were analyzed: Climate literacy, guidelines for K-12 global climate change education, and guidelines for effective climate change communication and message and so on. Many of the documents emphasize age appropriateness, positive thinking, participation and empowerment in climate change education while suggesting not to burden young learners with fears. Some documents such as the climate literacy suggest key concepts and/or essential principles of climate change education. Based upon the analysis, several considerations to incorporate the concepts in climate change into educational programs were suggested for further discussions.

This study, through the survey of citizens of Daegu in regard to the environment education experience and citizens perception, seeks to identify the order of importance and perception on the severity of environment. The survey has found that 36.4% citizens of Daegu have environment education experience. Those who have experience have high standard of living, live in high population density area and where pollutant generating plants are prevalent. In addition they are likely to live in apartment, are younger, and the higher the education level, more opportunities they have in getting environment education. The study has found that the environment education experience gives noticeable influence on environment perception, environment attitude, and environment activities. Also, those who have the environment education are likely to be interested in environment, know green growth policies, and are positive about local environment activities. Thus, they are willing to participate in activities to improve local environment and have emphasized the need for more environment education. As for what environment elements are most severe, they pointed to the "global warming and climate change" and "everyday garbage" and as for what are important, they chose "drinking water quality" and "global warming and climate change." Based on the study, we came to the conclusion that more environment education should be provided to elevate the interest in environment and subsequently, foster the sense of responsibility and civic mind toward the preservation of environment. In light of above, local governments must expand their supports and fully utilize the Local Agenda 21 to promote the education and increase the perception of citizens on the environment.

This research report cuts across management sciences (market strategy entry mode development) and innovative technology (Electric Vehicle (EV)) alongside measures to submerge global warming. The development of a successful entry mode for the electric Vehicle into the African continent is the main objective of the study. The study focuses on an analysis of how electric car manufacturers can enter the African market in other to achieve global sustainability and social responsibility. The methodology is based on identifying the factors that affect the choice of an entry mode into international markets by multinational companies desiring to leverage their revenue through a foreign market. It also offered a quantitative approach that can support the economic and sustainability entry mode model for EVs and a qualitative approach of Porter's five forces analysis as an entry mode coaching tool for EVs. These proxies are used in quite a wide range of multivariate statistical methods (trend analysis, ratio, and probability, comparative t-test technique, auto-regression, and ordinary least square technique). The result acknowledges joint venture and setting of the plant (physical presents) as the optimal entry mode in African EV market. It requires the EV manufacturers a tire-free emission innovation technology in order to optimize the global sustainability initiative.

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.

The purpose of this study was to investigate elementary school students' conceptions about the knowledge source and the mechanism about the greenhouse effect, and the relationship between the greenhouse effect and the global warming. Participants were 157 sixth graders (boy : n=79, girl : n=78) from six elementary schools located in the same city. The open-ended questionnaire was used to examine the students' spontaneous ideas depicted by their drawings and/or writings. The results of this study are as follows: First, although there is no the content on the greenhouse effect in the elementary school curriculum document, the children in this study indicated that the main source of their knowledge about the greenhouse effect came from 'school class' (31.8%); Second, although the children did not take a class about the greenhouse effect itself, 14.0% of children had a relatively high level of the mental model on the phenomenon; Third, more than 90% of the children did not have the correct understanding about the relation between the greenhouse effect and the global warming.

According to the energy hypothesis, the energy input per unit area primarily determines species richness in regions of roughly equal area. Some energy-related ecological research included identification of major climatic variables to determine regional species richness. In this study, the local butterfly species richness was examined to find out whether weather variables affected the local distribution or abundance of butterfly populations. Butterfly monitoring data from May 2001 to April 2002 taken at Mt. Yudal, Mokpo, in the southwestern part of Korea, and six weather variables (monthly mean values of temperature, precipitation, evaporation, wind speed, air pressure, and sunlight) were analyzed. Multiple regression analysis showed that only temperature explained 80% and 70% of the variability of log-transformed number of species and individuals, respectively, indicating that temperature played an important role in local species richness. Furthermore, global warming could affect the abundance and distribution of butterflies regionally as well as locally.
