  • In this study, a new methodology was proposed to evaluate the flood vulnerability of river levee and to investigate the effect on the levee where the water level changes according to climate change. The stability of levee against seepage was evaluated using SEEP/W model which is two-dimensional groundwater infiltration model. In addition to the infiltration behavior, it is necessary to analyze the vulnerability of the embankment considering the environmental conditions of the river due to climate change. In this study, the levee flood vulnerability index (LFVI) was newly developed by deriving the factors necessary for the analysis of the levee vulnerability. The size of river levee was investigated by selecting the target area. The selected levees were classified into upstream part, midstream part and downstream part at the nearside of Seoul in the Han river, and the safety factor of the levee was analyzed by applying the design flood level of the levee. The safety ratio of the levee was analyzed by applying the design flood level considering the current flood level and the scenario of climate change RCP8.5. The degree of change resulting from climate change was identified for each factor that forms the levee flood vulnerability index. By using the levee flood vulnerability index value utilizing these factors comprehensively, it was finally possible to estimate the vulnerability of levee due to climate change.

  • The purpose of this study is to analyze the 'Action Competence on Climate Change(ACoCC)' shown in 12 types of middle school 「Technology & Home Economics」 textbooks written according to the 2015 revised curriculum, and to suggest ways to improve the activity tasks. According to the results of the analysis, first, the 'knowledge on climate change' was the most frequently mentioned, and 'climate change communication' was the least frequently mentioned in the textbook among ACoCC. Second, all 12 textbooks dealt with 'knowledge about climate change' most frequently, yet the frequency of mentioning other competencies differed by publisher. In relation to the core concepts, the ACoCCs were most often discussed in the 'Management,' yet never discussed in the 'Life Design' at all. In relation to the academic sub-fields of home economics, the 'clothing life' showed the highest frequency of mentioning ACoCCs, while 'family life' the lowest frequency. Based on the results of the above analysis, it was suggested that the capacity to respond to climate change should be dealt with in the overall fields of home economics education. This study has implications as a basic study related to climate change in home economics education, and it is expected that various research and educational programs in home economics education that focus on climate change mitigation are implemented in the future.

  • We constructed climagraphs for 16 regions of Korea by using the average monthly minimum air temperature, maximum air temperature and global radiation. We characterized the outside climate requirements corresponding to the climate requirements of crops in greenhouses. The climagraphs allow to decide the appropriate climate periods for greenhouse cultivation without heating and cooling equipment. These graphs may be used for analyzing climatic characteristic of a given area, selecting the suitable region and greenhouse and making a rational plan for greenhouse cropping in Korea. We found difficulty in deciding the beginning and end of greenhouse heating and cooling period due to insufficient references.

  • When a weapon system is developed, climate elements such as temperature, rainfall, and so on have an effect on development costs and a developing period. Therefore, effects of environment and climate must be examined throughly before the design of weapon systems and be applied to their developments. And so, operational and storage requirements for weapon systems are determined and are applied to related tests through analyzing not only environmental factors such as vibration, shock, and so on, but also climate factors. In this paper, the distribution and the frequency of occurrence of rainfall were analyzed and were suggested as a good guide to determine standards of tests for weapon systems when it's raining.

  • The purpose of this paper is to study the effectiveness of a green roof by simple mathematical model. The developed model simulates a green roof during the summer. The results explain and support the claims in the literature such that effectiveness of a green roof depends on the climate condition, and on the insulation condition of the roof. If insolation can not be reduced more than 60% by the shading effects of a green roof, more active measures than green roof seem necessary. The analysis tools like presented in the paper is necessary especially to consider climate effect, to design, and also to test green roof.

  • Facing the global crisis of climate change, waterfront areas are experiencing a significant increase in property damages and casualties. In light of the climate change era, this paper aims to identify resilience strategies against rising sea levels and associated natural disasters. A comparison and analysis of resilience plans and strategies have been conducted for five waterfront cities. In conclusion, three key points are suggested. Firstly, establishing partnerships locally and globally is an emerging trend to effectively and collaboratively address climate change. Secondly, resilience is a fundamental concept in designing social, built, and cyber infrastructure, requiring attention from stakeholders. Lastly, designing a well-operating system is critical to respond effectively when external shocks or stress occurs.

  • Recently, the number of design for open-spaces at waterfront, such as open-air restaurant and cafeteria, has been increasing to provide openness and natural environment of waterfront. However, when planning open-air restaurant and cafeteria, it is essential to investigate the climate characteristic of waterfront, especially wind environment, since the waterfront has a special quality of climate like low-temperature and strong wind which differs from downtown or inland. In this study, wind environments of Haeundae, Suyoungman, and Gwanganli, the famous waterfronts in Busan, were investigated for design of open-air restaurants and open cafeterias. The main results were as follows. 1) the waterfront area of Haeundae, Suyoungman, and Gwanganli is suitable for open-air restaurant and open cafeterias; and 2) the appropriate period for open space in this area is from the end of March to November.

  • A Copula approach has the advantage of providing structural dependencies for representing multivariate distributions for the hydrometeorological variable marginal distribution involved, however, copulas are inflexible for extending in high dimensions, and satisfy certain assumptions to make the dependency. In addition, since the process of estimating design rainfall under the future climate associated with durations given a return period is mainly analyzed by 24-hour annual maximum rainfalls, the dependency structure contains information only on the daily and sub-daily extreme precipitation. Methods based on bivariate copula do not provide information for other duration's dependencies, which causes the intensity to be reversed. The vine copula has been proposed to process the multivariate analysis as vines consisting of trees with nodes and edges connecting pair-copula construction. In this study, we aimed to downscale under climate change to produce sub-daily extreme precipitation data considering different durations based on vine copula.

  • The purpose of this study is to develop a teaching-learning plans for middle school Home Economics that practices clothing life in response to climate change. Four steps of analysis, design, development, and evaluation were used for the research. 'Phenomenon and cause, impact (environmental, economic and social) and response (relaxation and adaptation)' were selected as educational content elements for climate change through reviewing the literature related to climate change. Six types of middle school Technology and Home Economics textbooks under the 2015 revised curriculum were analyzed using the selected content elements for climate change as the basis for analysis according to the data type(reading data, picture data, activity data) and clothing use cycle (production, purchase, use, and disposal). Based on the content elements of climate change in the clothing life area extracted through textbook analysis, a total of 12 teaching-learning plans in response to climate change were developed by utilizing various teaching and learning methods, data and media. The teaching-learning plans were designed based on an integrated understanding of the phenomena, causes, effects, and responses of climate change for the students to realize the seriousness of climate change and to exercise positive influence on families and society.
