  • Climate change assessment, together with climate change adaptation process, would be one of the worldwide important issues, and the study on climate change vulnerability indicator has been an essential problem for climate change adaptation. Vulnerability indicator can be used as a good tool to estimate the impact of climate change and to map out the distribution of its vulnerability over the given area both in Korea and other countries. This study addressed the conceptual summary on the assessment of climate change and its adaptation process. Previous studies on how to yield the vulnerability indicators of climate change are reviewed and several previous results of vulnerability indicators applied to Korean provinces are also discussed here.

  • This study was conducted to determine the phototactic response of Paratlanticus ussuriensis to different wavelength of light by the use of LEDs and to provide a basic information for developing an improved trap with the longer trapping efficiency to control environment-friendly this katydid. P. ussuriensis were attracted to the single LED light source, especially, blue and white. For the multiple LED light sources, the movement of P. ussuriensis was not significantly different among LED-light bands. Overall, P. ussuriensis had a tendency to move to light source although they were not attracted to a specific wavelength of light. These methods may be used as information for conducting a phototactic response of other insects.

  • Rice is a main crop and rice field is the most important farmland in Korea. This study was conducted to propose the methodology assessing impact and vulnerability on rice production by climate change at the regional and national level in Korea. We evaluated a vulnerability of rice paddy according to the outbreak of a main disease and pest of a rice plant. As results, Jeju-do, Gyeongsangnam-do, and Jeollanam-do were more vulnerable area than others. In contrast, the southern central region including Gyeonggi-do was less vulnerable than others. The vulnerable index was significantly higher in 2050s (0.5589) than in present (0.3500). This result showed that the vulnerable to the disease and pest enlarge in the future. The adaptive capacity highly contributed to the vulnerability assessment index. The daily maximum temperature of June and the daily average temperature from May to August also contributed the climate exposure index. The area of occurring sheath blight, rice leaf blast and striped rice borer was related to the system sensitivity index. The ability of water supply (readjustment area of arable land per paddy field area) and rice production technique (rice yield per hectare) were the highly contributed variables to the adaption capacity index.

  • This study investigated the effects of climate change project learning on elementary students' attitudes toward climate change and environmental literacy. Climate change project learning was conducted on 174 sixth-grade elementary school students in a metropolitan city (77 male, 97 female), after which their perceptions and attitudes toward climate change and environmental literacy were assessed. The climate change project learning had a positive effect on the students' perceptions and attitudes toward climate change, which was surmised because of the climate change content sharing and discussions during the project learning. The climate change project learning also had a positive effect on the students' environmental literacy, especially their environmental attitudes, values, and behavior; however, there were no statistically significant changes found for environmental sensitivity. This study highlights the educational effects and implications of environmentally focused climate change projectbased education for elementary school students.
