  • The study aimed to investigate the effects of climate adaptability and physical activity adherence on clothing behavior and health perception. Total usable questionnaires were obtained from 352 university students(126 male & 226 female students). Results were gained from the statistical analysis such as factor analysis, cluster analysis, ANOVA, t-test using SPSS 19.0. The results were as follows. First, male students showed higher figures than female students in physical activity adherence, cold adaptability, and health perception but vice versa in clothing behaviors related to the seasons, weather forecasts and the situation. Second, the group which had good physical activity adherence showed adequate clothing behaviors and fine health perception, which meant proper relations between exercise, clothing behavior, and health. Finally, the group which had lower climate adaptability but adequate clothing behavior according to the season showed a fine health perception. The relation between clothing behavior and health perception was checked through this.

  • The purpose of this paper is to investigate the characteristics of human constitution adapting to environment. Human constitution adapting to climate zone is basically classified into four types: The $Af^{\ominus}$ constitution adapting to warm-humid climate, the $Aw^{\ominus}$ constitution adapting to warm-arid climate, the $Dw^{\oplus}$ constitution adapting to cold-arid climate and the $Df^{\oplus}$ constitution adapting to cold-humid climate. The ${\ominus}constitution$ can be changed into a ${\oplus}constitution$ by adapting to cold climate or by heredity combination with the ${\oplus}constitution$. The ${\oplus}constitution$ can be changed into a ${\ominus}constitution$ by adapting to warm climate or by heredity combination with the ${\ominus}constitution$. The four constitution types consequently can be classified into eight types: The $Af^{\ominus}$ constitution, the $Af^{\oplus}$ constitution, the $Aw^{\ominus}$ constitution, the $Aw^{\oplus}$ constitution, the $Dw^{\oplus}$ constitution, the $Dw^{\ominus}$ constitution, the $Df^{\oplus}$ constitution and the $Df^{\ominus}$ constitution. This study investigated the characteristics of fingers of people with these constitutions and confirmed that the fingers of the ${\ominus}constitution$ man are longer, slender and cooler than the fingers of the ${\oplus}constitution$ man.

  • Objectives: In this study, an analysis was performed on local government adaptation plans for climate change focusing on the health sector. The limitations of past study results have been summarized and new research subjects for preparing for the advanced second period (2018-2022) of the local government adaptation plan for climate change have been suggested. Methods: First, a review of the literature related to vulnerability assessment and adaptation plans was performed. Next, a comparison among the 16 metropolitan governments' vulnerability assessment results and adaptation plans was made. Lastly, a classification of the adaptation policy and budgets to compare with their real budget amounts was performed. Results: The results show that there is a categorizing discrepancy between vulnerability assessment and adaptation policy. In addition, their adaptation budget amounts turned out to be too large in comparison with the actual budget amounts. Conclusion: The first period (2013-2017) local government adaptation plans for climate change had some limitations. This is because there was a rapid driving force for establishing adaptation plans under the green growth strategy in Korea. Now, we are confronting a risk of adaptation to climate change. By expanding this approach, the government would be able to set up a detailed policy to improve the plans during the second period.

  • This study attempts to facilitate climate change adaptation in conservation area by spatial planning of climate adaptation zone for endangered species. Spatial area is South Korea and select leopard cat (Prionailurus bengalensis) as a target species of this study. In order to specify the climate adaptation zone, firstly, Maximum entropy method (Maxent) was used to identify suitable habitat, and then core habitat was selected for leopard cat. Secondly, land use resistance index was evaluated and least cost distance was analyzed for target species. In this step we choose dispersal capacity of leopard cat to reflect species ecological characteristic. Finally, climate adaptation zone is described and adaptation measures are suggested. The presented approach could be generalized for application into conservation planning and restoration process. Furthermore, spatial planning of climate adaptation zone could increase heterogeneity of habitat and improve adaptive capacity of species and habitat itself.

  • Causing by green house gas emission, global warming is being accelerated significantly. This global warming cause world climate to change quiet different than before and we call this phenomenon is Climate Change. Environmental Impact Assessment being implemented in Korea is to prevent predicted environmental impacts from deteriorating within the domestic information and situation. As the climate change is getting severe, new meteorological records can be occurred which is exceeded existing statistical data. According to KMA(Korea Meteorological Administration) data, maximum value of precipitation and temperature in many regions changed with new data within last decade. And these events accompanied with landslides and flooding, and these also affected on water quality in rivers and lakes. According to impacts by climate change, disasters and accidents from heavy rain are the most apprehensive parts. And water pollution caused by overflowed non-point sources during heavy rain fall, fugitive dust caused by long-term drought, and sea level rise and Tsunami may affect on seaside industrial complex should be worth consideration. In this review, necessity of mutual consideration with influences of climate change was considered adding on existing guideline.

  • 도시침수는 사회 기반시설에 파괴적인 영향을 끼치고, 재산 및 인명 피해의 원인이 되므로, 고해상도 고정확도 예측 정보를 활용한 선제적 대응이 중요하다. 하지만, 기후변화로 인한 강수 강도의 증가, 도시의 확장 및 고밀화 등 토지피복 변화, 홍수방어시설의 노후화 등 여러 요인들의 복합적인 영향으로 인해 도시침수의 정확한 재현 및 예측은 여전히 난제로 남아 있다. 천수 방정식(Shallow Water Equations)을 기반으로 하는 물리과정 모형은 신뢰도 높은 예측 결과를 제공할 수 있지만, Courant-Friedrichs-Lewy 조건 등의 제약으로 인해 대규모 도시 지역의 고해상도 실시간 예측에는 적합하지 않은 한계가 있다. 본 연구에서는 상대적으로 간단한 연산 규칙의 중첩을 통해 복잡계 물리 시스템을 모의하는 셀룰러 오토마타(Cellular Automata; CA) 기술에 기반한 도시침수 해석 모형인 CA-Urban을 개발하고, 미국 Oregon 주 북서쪽에 위치한 Portland시의 도심지역에 대해 침수해석의 적용성을 평가한다. 세부적으로는, 기존 셀룰러 오토마타 기반 침수해석알고리즘의 수치 진동(Oscillation) 문제에 대한 원인을 분석하고, 안정성 향상 방법인 셀 간 최대유량 제한, 가중치 적용 기법, 모형의 계산 효율성 향상을 위한 최적 적응 시간 단계 기법(Adaptive time step)의 적용 결과를 소개한다. 또한, 침투 및 증발산 등 물순환 요소 해석 모듈의 개발 성과 및 방향에 대해서 토의한다.
