The purpose of this study is to examine the perception of early childhood teachers on ecological art activities oriented to education for sustainable development. The research results are as follows. First, Early childhood teachers recognized the visual art of natural media, the pursuit of community values, and the participation and communication of social members as educational significance of ecological art activities. And difficulties in practicing ecological art were recognized as lack of educational environment, lack of ecological art teaching materials and specific examples, and teachers' lack of understanding of ecological art. Also, they recognized that ecological art activities foster core competencies in art experience area, such as nature-friendly communication skills, eco-friendly sensibility, and creative convergence skills. Second, regarding ecological art activities and sustainable development education, early childhood teachers considered the difficulties in practice as lack of awareness about sustainable development, lack of play meia and materials, lack of educational policies and support, and insufficient teacher training programs. Also, regarding the SDGs that can be practiced in ecological art activities, teachers were found to be highly aware of 'grow affordable and clean energy', 'improve clean water and sanitation', 'provide quality education' in the order. In the contents of education for sustainable development that can be practiced in ecological art activities, teachers are given the order of 'climate change response', 'clean energy', 'water and sanitation', 'quality education', 'health and well-being' and 'marine ecosystem'. was highly recognized. If an ecological art activity program is developed, the rate of responding that it will be used is high, so it is considered that the development of an ESD-oriented ecological art activity program is urgent.

The Earth's surface temperature still continues to rise, and extreme weather phenomena such as heat waves, drought, and precipitation have been repeated every year. It is reported that international communities attribute the main cause of the Earth's surface temperature rise to the excessive use of the fossil energy. Recently, the damage caused by climate change is getting worse, and the place where we live is suffering the most. Cities have been continuously growing not only meeting the basic functions of human habitation, work and leisure but also being places for various economic and social activities. But Cities, the victims of climate change, have grown only considering human needs and convenience rather than predicting their physical and ecological systems(Albedo effects, urban microclimate, resources and energy of the circulatory system, etc). In other words, the cities offer the cause of the problems of climate change, and even worsen the extreme weather phenomena without coping with them. Therefore, it is urgent priorities to protect the climate, to prevent the causes of the extreme weather phenomena and to enhance the adaptive capacity for the worse weather events. This study is to derive the concept for adapting to these climate changes which can make cities escape from exposure to these climate change impacts and make themselves safer places to live. And it analyzes some European cities and present developing models to implement planning methods. In this study, the concept of the climate adaptive cities will be suggested to prepare the adaptation measures for urban planners, and climate change adaptation models will be presented by analyzing some preliminary cases.

The systematic data management system in the area of river flow analysis has not yet constructed, even though the need is evident due to the complicated process of tremendous input/output data in the modeling study and the importance of visualization of spatial flow variation. The objectives of this study are to suggest the method for analysis of changing river sections affecting ecological habitat characteristics. The effects of ecological habitat characteristics are assessed with respect to changing river sections. A GIS special analysis is created representing in the past section of Nonsan-river using historical data. Topographic surfaces are subject to erosional and depositional forces that a specific set of surface characteristics unique to elevation data. GIS spatial analyst is used to generate surface grids from historical point data. Using the GIS spatial analyst can be constructed sections for anywhere of river. The change of depth between 1979 and 1988, the left bank elevations of a river are increased about 1.5m. But the right bank elevations of a river are decreased about 2.3m caused by erosion. In addition, the change of spatial between 1988 and 2002, the regions of a river from upper stream to midstream are decreased the elevation. But the downstream regions are increased the elevation. These changes are analyzed in GIS program to assess methods for affecting ecological habitat.

The 1972 United Nations Conference on the Human Environment sparked off actions aimed at protecting the ocean on all scales. Physical science was essentially in the foreground, and the ecological dimension remained in the background as well. During the following two decades, ocean uses increased and spread unexpectedly, and there was an urgent need for management patterns to deal with coastal areas, regional seas, and with the ocean as a whole. Meanwhile, mainly thanks to the Man and the Biosphere (MAB) programme, the ecological dimension of the environmental issue became more evident, while the concept of sustainable development was designed by the World Commission on Environment and Development (1987). As far as the ocean is concerned, by adopting Agenda 21, the 1992 Conference on Environment and Development (UNCED) could neither embrace a wholly ecology-oriented policy, nor adopt the concept of sustainable development in its whole extent. This circumstance encourages efforts to consider the ocean from an effective ecological perspective, and to explore how cultural and ecological systems have interacted. Hence the concept of diversity becomes an increasingly key factor.

This study aimed to suggest priority for developing emission factor (EF) and to develop the methodology of quantitative assessment of EF in the forestry sector. Based on the stock-difference method, 17 kinds of EFs (27 EFs based on forest types) were required to calculate the carbon emission in the forestry sector. Priority for developing EFs followed the standards, which is a development plan by the government agency, importance of carbon stock for greenhouse gas, and EFs by the species. Currently, the most urgent development of EFs was carbon fraction in biomass and carbon stock in dead wood. Meanwhile, the quantitative assessment of EF consisted of 7 categories (5 categories of compulsory and 2 categories of quality evaluation) and 12 verification factors. Category in compulsory verification consisted of administrative document, determination methodology of emission factors, emission characteristic, accuracy of measurement and analysis, and data representative. Category in quality evaluation consisted of data management and uncertainty estimates. Based on the importance of factors in the verification process, each factor was scored separately, however, the score needs to be coordinated by the government agency. These results would help build a reliable and accurate greenhouse gas inventory report of Korea.

This study is conducted to estimate potential evapotranspiration of 10 weather observing systems in Andong Dam watershed with FAO56 Penman-Monteith (FAO56 PM) methodology using the meteorological data from 2013 to 2014. Also, assuming that there is no solar radiation data, humidity data or wind speed data, the potential evapotranspiration was estimated by FAO56 PM and the results were evaluated to discuss whether the methodology is applicable when meteorological dataset is not available. Then, the potential evapotranspiration was estimated with Hargreaves method and compared with the potential evapotranspiration estimated by FAO56 PM only with the temperature dataset. As to compare the potential evapotranspiration estimated from the complete meteorological dataset and that estimated from limited dataset, statistical analysis was performed using the Root Mean Square Error (RMSE), the Mean Bias Error (MBE), the Mean Absolute Error (MAE) and the coefficient of determination ($R^2$). Also the Inverse Distance Weighted (IDW) method was performed to conduct spatial analysis. From the result, even when the meteorological data is limited, FAO56 PM showed relatively high accuracy in calculating potential evapotranspiration by estimating the meteorological data.

Jeju Island is managed intensively in terms of environmental and ecological aspect because of its extraordinary ecosystem types comprising numerous rare, protected flora and fauna. To depict rapid change of habitat status in Jeju Island, the InVEST Habitat Quality model has been operated and compared analytically with the Eco-Natural map. The Habitat Quality map of Jeju Island is turned out to have similar inclination with Eco-Natural map. We compared the average habitat quality value in each Eco-natural map class in Jeju Island and the habitat quality value of first second third grade and non-included area decreased as 0.95 0.76, 0.53 and 0.37 in eco natural map respectively. Compared to biodiversity map based on biological investigation, the result of the InVEST habitat quality model can be simply obtained by land cover map with threat and sensitivity data. Further studies are needed to make explicit coefficients for Jeju Island and Korean peninsula, then the Habitat Quality model could be applied to past and future scenarios to analyze extent of habitat degradation in time series to help decision makers.

We developed an educational program using soil seed bank for promoting ecological literacy of children. The initial program was based on the modification of scientific methods used by ecologists. A pilot application was conducted to 4th~6th grade students. In that result, the program was most effective to 4th grade students in terms of ecological knowledge and attitude. Observation of plants in outdoor was the most interesting activity and soil seed bank experiment was the most useful activity to the students. The educational period from late March to early November was too long to keep interest for participants. In the final program, we suggested 3 months and 2 weeks education period (from the 4th week of March to the first week of July) and the 4th grade students as a target. The program consisted of 7 activities, which are "Beginning the soil seed banks observation", "Comparing plant community in each soil seed bank", "My friends, sprout", "How do you come here?", "Finding the hided plants in my school garden", "Why did the soil seed banks change?", and "Inquiring about relationship between plants and their environments". These activities include the process of student's participation of sampling and setting soil seed banks around their school, and observing and identifying the seedlings. Through these activities, students can understand the concept of soil seed banks, develop their ecological knowledge, eco-centric attitude, and ecological sensibility and inquire about the relationship between vegetation from soil seed banks and their environments.

The purpose of this study is to investigate the change in ecological footprint made by the eco-friendly consumer education program, and ultimately, to help the high school students, future consumers, have eco-friendly attitude. This study will be contributed to helping them to understand the importance of the eco-friendly consumption and the seriousness of the environmental problems arising from their bad consumption habit, to get interested in the environmental problems in daily lives, and to reduce the ecological footprint through the eco-friendly habit acquired when young. This study is designed to have 60 high school students experience the eco-friendly consumer education program for 10 months and compare the levels of each ecological footprint though two different Questionnaires in five sections: housing, food, transportation, purchase, and waste. The program used in this research consists of three parts: eco-friendly attitude education for consumers, eco-friendly citizen education for consumers, and eco-friendly resource management education for consumers. The data are analyzed by SPSS Window 10.0 program. The findings are as follows: First. The eco-friendly consumer education is more likely to help the students develop critical thought and eco-friendly attitude, unlike the economy-related consumer education. Second. The level of ecological footprint is significantly decreased in the group with the eco-friendly consumer education program. compared to the group without it. Third. Experiencing the eco-friendly consumer education program helps the students have the positive attitude on ecology and lead an environmentally sustainable consumer life. The results show that eco-friendly consumer education can make a contribution to raising the good citizens who have eco-friendly attitude and behavior, lead sustainable consumer life, and try to reduce the level of ecological footprint.

This manuscript describes the relationship between climate change and forest growth, forest species, carbon stocks, and tree mortality. 1) In the aspect of forest growth, the growth of major coniferous species, including Pinus densiflora, had a negative correlation with temperature. On the other hand, major deciduous oak species, including Quercus variabilis and Quercus mongolica, had a positive correlation with temperature. 2) When considered in the aspect of the forest species distribution, various models commonly showed a decrease in the distribution of coniferous species and an increase in oak species due to climate change in the medium to long term. 3) From the carbon stock perspective, there was a difference in the estimation according to the status of forest management. Most of Korean forests will mature to become over-matured forest after year 2030 and are estimated to produce approximately 410 million ton forest biomass until 2090 with the current cutting regulations for sustainable forest management announced by the Korean Forest Service. 4) In the forest mortality, the mortality rate of the major coniferous species showed a clear tendency to increase higher temperatures while it decreased for the oak species with no verification of statistical significance. Moreover, the mortality of the subalpine coniferous species was projected to progress rapidly. considering the overall impacts described above, there should be a management strategy for coniferous species that are relatively vulnerable to climate change. Moreover, a sustainable forest plan in the aspect of ecosystem services, carbon sequestration and storage, which is linked to global issues such as Sustainable Development Goals, ecosystem services and negative emission.
