  • 토양수분은 물 순환의 필수적인 요소로써 수문순환 및 기상 현상에 큰 영향을 미친다. 현재 우리나라에서는 토양수분 자료구축을 위해 Frequency Domain Reflectometry (FDR), Time Domain Reflectometry (TDR) 센서를 활용하여 지점 단위 토양수분 자료를 생산하고 있다. 그러나 한반도는 도서, 산간 지역이 다수 분포하고 있어, 지점관측 센서만으로 공간 대표성을 갖는 토양수분 자료를 산출하기 어렵다. 이에, 광범위한 지역을 장기간 모니터링 할 수 있는 원격탐사 기법을 활용하여, Advanced SCATterometer (ASCAT), Soil Moisture Active and Passive (SMAP) 등의 공간 단위 토양수분 자료의 적용성이 평가되고 있다. 하지만, 공간 토양수분 자료의 검증을 위해 필수적인 지점 토양수분 자료가 구축되지 않은 미계측지역이 다수 존재하며, 한반도와 같이 지형적 복잡성이 높게 나타나는 지역에서는 계측지역에서의 활용성 평가 결과가 미계측지역에서도 유사하게 나타난다고 가정하기 어렵다. 이에 본 연구에서는, 미계측지역의 공간 토양수분 자료를 산출하고자 계측지역에서 SM2RAIN 알고리즘으로 산출된 강수량 자료와 위성 산출 자료 그리고 지점관측 자료의 관계성을 분석했다. SM2RAIN 알고리즘의 입력자료는 Advanced SCATterometer (ASCAT) 토양수분 자료를 활용했다. ASCAT 토양수분 자료와 SM2RAIN 강수 자료의 검증을 위해 기상청에서 제공하는 Automated Agriculture Observing System (AAOS) 토양수분 자료, Automatic Weather System (AWS) 강수량 자료와 Global Precipitation Measurement (GPM) 강수 자료를 활용하였다. 전반적으로 ASCAT 토양수분을 통해 산출한 SM2RAIN 강수량의 추정과GPM 강수량이 유의미한 상관성이 나타나는 것을 확인할 수 있었으며, 추후 Downscaling 기법과 연계하여 지형적 복잡성이 높게 나타나는 지역의 토양수분 추정이 가능할 것으로 기대된다.

  • The study in this paper considers how elementary school students' interest in mathematics and STEAM literacy could be promoted by conjoining the learning of mathematics with the learning of drone topics. Survey instrument was developed to measure student attitudes toward mathematics and science subjects and to evaluate student beliefs on learning mathematics embedded in science topics. Data were collected from elementary school students by administering pre- and post-tests: students were intervened with examples of math problems embedded in certain science contexts. The findings indicate that elementary school students' experience of solving mathematics problems embedded in science contexts positively affects the promotion of their attitudes toward, beliefs on science subjects and science and engineering career path selection. We hope that the mathematics program using the drone will be used in the classroom for STEAM.

  • Humanities and social sciences researchers and database experts have teamed up to build a database of IPR materials prepared by the Institute of Pacific Relations (IPR). This paper presents the issues and solutions inherent in the database construction for ensuring the quality of IPR materials. For the accessibility of the database, we maintain the database on the Web so that researchers can access it via web browsers; for the convenience of the database construction, we provide an integrated interface that allows researchers to perform all tasks in it; for the completeness of IPR materials constructed, we support the responsible input and the responsible approval that identify responsibilities of each IPR material entered; and for the immediacy of the approval, we support an interactive approval process facilitating the input of researchers. We also use database design, query processing, transaction management, and search and sorting techniques to ensure the correctness of IPR materials entered. In particular, through concurrency control using existence dependency relationships between records, we ensure the correctness between the operating system files and their paths. Our future studies include content search, database download and upload, and copyright related work on IPR materials.
