  • Recent trends in U.S. ocean policy were briefly reviewed through the keywords in the documents from the three consecutive administrative offices of U.S. government since 2010. Many keywords was unchanged since 2010 implying that the confirm foundation of US ocean policy is not easily shaken. Among the administration-specific main drivers, emphases on Coastal and Marine Spatial Planning in 2010, Ocean Mapping in 2019, and the 2021 goal of conserving 30% by 2030 may profoundly affect the directions of U.S. ocean environment conservation policy. Decadal trends and implications in main key words of U.S. ocean policy as are reflected from the documents produced by the above three administrative offices were also shown to affect future perspectives of global ocean environment conservation policy as well as the corresponding Korean policies.

  • 우리나라는 전체 면적의 63.0%가 산림으로 구성되어 있고, 일정면적 내 나무들의 총 부피를 의미하는 입목축적의 경우 1973년에 11.3 m3/ha에서 2015년에 146.0 m3/ha로 43년 동안 1292.0% 증가하였다. 이에 본 연구에서는 유역 면적의 70.2%가 산림에 해당하는 용담댐 상류 유역(930.2 km2)을 대상으로 SWAT(Soil and Water Assessment Tool)을 이용하여 장기간 산림 성장에 따른 수문 변화를 평가하였다. 산림 성장 변화 분석을 위해 산림청의 전국산림자원조사에서 제공하는 침엽수, 활엽수, 혼효림 식생 자료를 1980년부터 2019년까지 40년의 산림 성장 자료를 10년 단위(1980s; 1980~1989, 1990s; 1990~1999, 2000s; 2000~2009, 2010s; 2010~2019)로 구축하였으며, Terra MODIS MOD15A2 엽면적지수(LAI) 자료를 2010년부터 2019년까지 구축하였다. LAI는 연대별 식생 높이의 상관성을 고려하여 1980년부터 2019년까지 회귀하여 총 40년 자료를 구축하고 10년 단위로 활용하였다. SWAT의 검보정은 2010년부터 2019년까지 실측된 유량, 증발산량 및 토양수분을 이용하였으며 검보정 결과 유량의 평균 NSE는 0.57, R2는 0.69, RMSE는 1.66 mm/day, PBIAS는 4.95%이며, 증발산량 및 토양수분의 R2는 0.60, 0.52로 나타났다. 산림 성장에 따른 수문 변화를 관찰하기 위해 기상자료를 2010s로 고정하고 연대별 산림 정보를 입력하여 산림 성장이 물순환에 미치는 영향을 시공간적으로 평가할 예정이며, 침엽수, 활엽수, 혼효림 생장을 개별적으로 분석하여 식생별 영향을 비교 및 평가할 예정이다.

  • This study intended to identify the relationship between textile print designs for local apparel, and fashion trends. This was achieved by extracting trend key words and analyzing apparel textiles. The fashion trends and print trends from the 2010S/S season to the 2013F/W season as projected by two trend forecasters, the Samsung Fashion Institute and First View Korea, were extracted for a comparative analysis. In terms of clothing patterns, a total of 1,582 print designs purchased by local apparel brands targeting women in their 20s and 30s from print design companies including Italy's NEWAGE, MyDesign and England's Pattern, were analyzed. After classifying the designs according to the trend key words which had been extracted, the demands by season, trend dependency, and design preferences were analyzed to produce the following results. The major key words for textile print designs from the 2010S/S season to the 2013F/W season were Check & Stripe, Flower, Geometric, Natural, Ethnic, and Graphical. Patterns corresponding to those design key words were more prominent in recent designs. Considering the trends by season, the designs presented in the F/W season were found to be more likely to correspond to the trend key words than those in the S/S season. A general preference for nature-inspired designs was also found in the local print market.
