We explored the possibilities of science field experience in Jongmyo Shrine in this study. To understand the educational value of self-leading science activities in Jongmyo Shrine, one of the World Heritage, we developed science program and applied it to the elementary students participating in a gifted education center. We collected and analyzed various data of opinionnaire survey before and after the program, field activity sheets, field observation, and individual- and group interview. The results showed the lack of students' spatial ability and proposed educational interests in science education. Also, a lot of students felt the difficulty in applying school science knowledge into the real life context. Students found the meaning of science learning through cooperative activities in the historically meaningful place. A proper use of smart device in science field experience was recommended. We found that activities with too much smart device might impede various scientific process skills.

Although the era of very large telescopes has come, small telescopes still have advantages for fast follow-up and long-term monitoring observation. Intensive monitoring survey of nearby galaxies (IMSNG) aims to understand the nature of the supernovae (SNe) by catching the early light curve from them with the network of small telescopes from 0.4-m to 1.0-m all around the world. To achieve the scientific goals with heterogeneous facilities, three factors are important. First, automatic processes as soon as data is uploaded will increase efficiency and shorten the time. Second, searching for transients is necessary to deal with newly emerged transients for fast follow-up observation. Finally, the Integrated process for different telescopes gives a homogeneous output, which will eventually make connections with the database easy. Here, we introduce the integrated pipeline, 'gppy' based on Python, for more than 10 facilities having various configurations and its performance. Processes consist of image pre-process, photometry, image align, image combine, photometry, and transient search. In the connected database, homogeneous output is summarized and analyzed additionally to filter transient candidates with light curves. This talk will suggest the future work to improve the performance and usability on the other projects, gravitational wave electromagnetic wave counterpart in Korea Observatory (GECKO), and small telescope network of Korea (SOMANGNET).

BITSE is a project of balloon-borne experiments for a next-generation solar coronagraph developed by a collaboration with KASI and NASA. The coronagraph is built to observe the linearly polarized brightness of solar corona with a polarization camera, a filter wheel, and an aperture door. For the observation, the coronagraph is supported by the power distribution unit (PDU), a pointing system WASP (Wallops Arc-Second Pointer), telemetry & telecommand system SIP (Support Instrument Package) which are developed at NASA's Goddard Space Flight Center, Wallops Flight Facility, and Columbia Scientific Balloon Facility. The BITSE Command and Data Handling (C&DH) system used a cost-off-the-shelf electronics to process all data sent and received by the coronagraph, including the support system operation by RS232/422, USB3, Ethernet, and digital and analog signals. The flight software is developed using the core Flight System (cFS) which is a reusable software framework and set of reusable software applications which take advantage of a rich heritage of successful space mission of NASA. The flight software can process encoding and decoding data, control the subsystems, and provide observation autonomy. We developed a python-based testing framework to improve software reliability. The flight software development is one of the crucial contributions of KASI and an important milestone for the next project which is developing a solar coronagraph to be installed at International Space Station.

이 연구에서는 2007 개정 교육과정에 따른 중학교 과학 1 교과서 '식물의 영양' 단원의 탐구활동과 이와 관련되는 제7차 교육과정에 따른 중학교 과학 2 교과서 '식물의 구조와 기능' 단원의 탐구활동을 탐구 내용 영역, 탐구 과정 영역, 탐구 상황 영역의 3차원 분석틀을 이용하여 분석하였다. '식물의 영양' 단원의 평균 탐구활동의 수는 9.2개로 '식물의 구조와 기능' 단원의 경우보다 3.8개 줄었다. 그리고 두 단원에서 공통적으로 다루는 주제도 있는 반면, 교육과정 개정에 따른 내용의 변화를 반영하여 중점을 두는 탐구활동 주제가 달라진 경우도 있었다. 두 단원 모두 기초 탐구 과정에서는 '관찰', 통합 탐구 과정에서는 '자료해석'의 비율이 높았고, '실험관찰'에 해당되는 비율이 매우 높게 나타났으며, '순수과학적 상황'의 비율이 높게 나타났다. '식물의 영양' 단원에서는 기초 탐구 요소보다 통합 탐구 요소를 더 많이 다루고 있고, '해보기'에 해당하는 탐구활동 수가 증가하고 '모의활동'이 제시된 점이 특징적이며, '개인적 상황'의 비율이 늘었고 '기술적 상황'과 '자연환경적 상황'이 제시된 탐구활동도 나타났다. 중학교 과학 교과서 개발 시 탐구활동이 보다 다양해지도록 탐구활동의 내용, 탐구 과정, 유형, 상황 등의 측면을 고려해야 할 것이다.

The United States (US) National Science Foundation's (NSF's) National Ecological Observatory Network (NEON) is a continental-scale observation facility, constructed and operated by Battelle, that collects long-term ecological data to better understand and forecast how US ecosystems are changing. All data and samples are collected using standardized methods at 81 field sites across the US and are freely and openly available through the NEON data portal, application programming interface (API), and the NEON Biorepository. NSF led a decade-long design process with the research community, including numerous workshops to inform the key features of NEON, culminating in a formal final design review with an expert panel in 2009. The NEON construction phase began in 2012 and was completed in May 2019, when the observatory began the full operations phase. Full operations are defined as all 81 NEON sites completely built and fully operational, with data being collected using instrumented and observational methods. The intent of the NSF is for NEON operations to continue over a 30-year period. Each challenge encountered, problem solved, and risk realized on NEON offers up lessons learned for constructing and operating distributed ecological data collection infrastructure and data networks. NEON's construction phase included offices, labs, towers, aquatic instrumentation, terrestrial sampling plots, permits, development and testing of the instrumentation and associated cyberinfrastructure, and the development of community-supported collection plans. Although colocation of some sites with existing research sites and use of mostly "off the shelf" instrumentation was part of the design, successful completion of the construction phase required the development of new technologies and software for collecting and processing the hundreds of samples and 5.6 billion data records a day produced across NEON. Continued operation of NEON involves reexamining the decisions made in the past and using the input of the scientific community to evolve, upgrade, and improve data collection and resiliency at the field sites. Successes to date include improvements in flexibility and resilience for aquatic infrastructure designs, improved engagement with the scientific community that uses NEON data, and enhanced methods to deal with obsolescence of the instrumentation and infrastructure across the observatory.
