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.

Recently, since the risk on natural disasters is increasing due to abnormal weather such as the global warming, a need for a system on prior review on the influence of disasters has emerged in order to establish a solution by analyzing elements of disaster in advance. However, since the inherently destroying business namely the quarrying business is excluded from the range of subject business of Prior Review System on the influence of disasters, a correction for this is required. In order to actually explore how much risk it contains, actual outflow of soil and flood in the quarrying block where quarrying is being currently carried out was examined and the required undercurrent facility capacity which is also used as a grit chamber was investigated. In addition, by comparing the soil outflow of industrial complexes and golf courses which are current subject businesses of Prior Review on the Influence of Disasters and that of rock mountains relative risk level was examined. After investigation, it was found that the risk on occurrence of disasters was increased due to increase in outflow of soil and flood because of the change of land condition during and after development thus an adequate solution to decrease is required. In addition, after comparison with other business groups it was found that a significantly higher amount of soil is outflown in case of rock mountains thus it was analyzed that a solution to decrease is required. Therefore, a correction is immediately required in order to include quarrying business in the subject business of Prior Review System on the Influence of Disasters.

In order to how well predict ISCST3(lndustrial Source Complex Short Term version 3) model dispersion of air pollutant at point source, sensitivity was analysed necessary parameters change. ISCST3 model is Gaussian plume model. Model calculation was performed with change of the wind speed, atmospheric stability and mixing height while the wind direction and ambient temperature are fixed. Fixed factors are wind direction as the south wind(l80") and temperature as 298 K(25 "C). Model's sensitivity is analyzed as wind speed, atmospheric stability and mixing height change. Data of stack are input by inner diameter of 2m, stack height of 30m, emission temperature of 40 "C, outlet velocity of 10m/s. On the whole, main factor which affects in atmospheric dispersion is wind speed and atmospheric stability at ISCST3 model. However it is effect of atmospheric stability rather than effect of distance downwind. Factor that exert big influence in determining point of maximum concentration is wind speed. Meanwhile, influence of mixing height is a little or almost not.

Water problems recently, not only influence environmental issues such as water quality and water management but also influence socioeconomic issues such as poverty, gender, and regional conflicts. Therefore there is increasing attention on water education as part of the environmental education. Yet water education in formal education is only treated with particular subjects like science and social studies with limited contents which fails to cover the social, economic problems related to water thoroughly. Also, though there is an active water education on the field of informal education. its contents are also very limited. Water education requires the implementation of a comprehensive and holistic approach that can holistically consider economic and social problems as well as environmental problems. Therefore in this research, 'water education for sustainable development' is set up as a direction of contents development which include interdisciplinary and holistic aspects. Contents development of water education for sustainable development is an reflection of the experts and teacher's opinions and contain of: main category dividing into three pillars of sustainable development such as environment, economy, and society, and subcategory covering environmental science's objective including knowledge, skill, attitude, and action as well as local, national, regional, and global issues.

The deteriorating role of Nakdong River due to the Four Major Rivers Project has caused a series of problems, including water pollution, drying streams, aggravation of the hydroecology. Geumho River and Gyeongseong-cheon had a higher concentration index and is believed to impact the water quality of the main stream. The influence index of Geumho River and Nam River between 2015 and 2016, which have a large amount of discharge, was the highest among the tributaries in terms of the load material balance. Showing the highest average concentration and average load in the index assessment, Geumho River is believed to require an intensive management for improving the water quality of the main stream. Furthermore, when the cumulative percentage of the average concentration and average load was compared based on the water quality improvement of the tributaries mixed to Nakdong River, which was set to 60%, Geumho River, Nam River, Topyeong-cheon, and Cha-cheon, which showed the highest ratio in that order, were determined to require a water quality management program as a priority.

Purpose: The purpose of this study is the time series analysis for predicting the yield of crops applicable to each farm using environmental variables measured by smart farms cultivating tomato. In addition, it is intended to confirm the influence of environmental variables using a deep learning model that can be explained to some extent. Methods: A time series analysis was performed to predict production using environmental variables measured at 75 smart farms cultivating tomato in two periods. An LSTM-based encoder-decoder model was used for cases of several farms with similar length. In particular, Dual Attention Mechanism was applied to use environmental variables as exogenous variables and to confirm their influence. Results: As a result of the analysis, Dual Attention LSTM with a window size of 12 weeks showed the best predictive power. It was verified that the environmental variables has a similar effect on prediction through wieghtss extracted from the prediction model, and it was also verified that the previous time point has a greater effect than the time point close to the prediction point. Conclusion: It is expected that it will be possible to attempt various crops as a model that can be explained by supplementing the shortcomings of general deep learning model.

The objective of this study was to explore how different types of rewards affect customers' inclinations to engage in environmental activities promoted through restaurant social media platforms. In addition, we investigated the potential moderating role of customer level of participation within the social media community. A total of 202 valid responses obtained by distributing a self-administered survey among restaurant patrons were subjected to hierarchical regression analysis to examine relationships between variables. The findings underscored the significant influence of economic and social rewards on shaping customer intent to participate in environmental initiatives promoted within restaurant social media communities. Furthermore, the study revealed that the extent of customer participation within the social media community moderated the relationship between rewards and their likelihood to partake in environmentally conscious behaviors. These results have meaningful implications for restaurant managers seeking to promote environmental initiatives effectively through social media platforms and within their establishments.

This study examined the influence of social responsibility awareness (economic and social-environmental responsibility) and trust in corporate social responsibility on sustainable diets. The subjects of the study were 468 university students. The main research results were as follows. First, the social responsibility awareness of the study subjects was 4.03±0.72 points for economic responsibility and 3.48±0.81 points for social-environmental responsibility. An awareness of economic responsibility showed differences according to gender. Trust in corporate social responsibility was 3.62±0.61 points, and there was no statistical significance based on gender. Second, the level of a sustainable diet was food safety and consideration (4.06±0.63), knowledge of the environment and diet (3.94±0.68), understanding of the food circulation system (3.45±0.77), and healthy diet (3.26±0.89). Among the factors influencing a sustainable diet, female students had higher attitudes toward food safety and consideration and understanding of the food circulation system than male students. Third, the social responsibility awareness (economic responsibility and social-environmental responsibility) and corporate social responsibility trust variables influenced university students' sustainable diet. Among these, social-environmental responsibility awareness had the highest influence.
