이 연구에서는 5명의 지구과학 교사를 대상으로 심층 면담을 통해 천체 관측 활동 경험이 가지는 의미를 현상학적으로 탐색하였다. 연구 참여자에게 Seidman의 3단계 면담법을 수정하여 개발한 질문지를 제공하고, 반구조화된 면담을 거쳐 자료를 수집하였다. 면담 자료의 분석을 거쳐 천체 관측 활동의 교육적 함의를 도출하였다. 교사들은 교원양성과정에서 수강한 관측 천문학 실습 강의를 통해 천문학과 관측에 대한 체계적인 기초 지식을 형성하였고, 교사가 된 이후에는 주로 동료 교사들의 도움을 얻어 실질적으로 천체 관측 활동을 수행하는 요령을 익혔다. 학생들을 대상으로 한 천체 관측 활동을 기획하고 실행하면서 교사들은 학생의 인지적 영역, 정의적 영역, 진로에 대한 인식에서 긍정적인 변화를 확인하였고, 따라서 천체 관측 활동의 교육적 가치를 높이 평가하였다. 천체 관측 활동은 교사 본인에게도 매우 큰 보람과 만족감을 주는 활동이고, 지구과학 교사로서의 자긍심을 고취하는 기능이 있는 것으로 확인되었다. 그러나 교사들은 학교 현장에서 관측 활동을 수행하는 과정에서 내적/외적인 장애 요인으로 인한 어려움을 경험하고 있었다. 교사들이 천체 관측 활동을 시도하거나 지속하기 위해서는 내적 장애 요인의 해결이 더 중요한 것으로 나타났으며, 이를 위해서는 적절한 시기의 연수를 통한 내용적 지원으로 자신감을 북돋아 주고, 교사 연구회와 같은 동료 집단에서 경험을 공유할 기회를 제공할 필요가 있다.

Based on our experience on exoplanet transit observation, we propose the exoplanet science cases with Small Telescope Network. One is the follow-up observation for validation of exoplanet candidates. TESS(Transiting Exoplanet Survey Satellite) is pouring out exoplanet candidates in bright stars(V<15) on all the sky. Since Small Telescope Network will consist of 0.5-1m telescopes, we will expect to produce promising outcomes from the follow-up observation of bright candidates. Next is the transit time observation. By spectroscopy of space and large telescopes during transit event, it can be possible to find the bio signatures in exoplanet atmosphere. So, in terms of cost, it is critical to determine the exact time of transit event. In addition, detecting the variation of transit time can reveal another exoplanet and exomoon in the system. In order to determine the transit time and its variation, the accumulation of transit event data is more important than the quality of photometric data. We expect that it can be a challenging project of Small Telescope Network.

The application of software engineering is not common in the development of astronomical observation system. While there were component-wise developments in the past, large-scale comprehensive system developments are more common in these days. In this study, current methodologies of development are reviewed to select a proper one for the development of astronomical observation system and the result of the application is presented. As the subject of this study, a project of operation software development for an astronomical observation system which runs on the ground is selected. And the output management technique based on Component Based Development which is one of the relatively recent methodologies has been applied. Since the nature of the system requires lots of arithmetic algorithms and it has great impact on the overall performance of the entire system, a prototype model is developed to verify major functions and performance. Consequently, it was possible to verify the compliance with the product requirements through the requirement tracing table and also it was possible to keep to the schedule. Besides, it was suggested that a few improvements could be possible based on the experience of the application of conventional output management technique. This study is the first application of the software development methodology in the domestic astronomical observation system area. The process and results of this study would contribute to the investigation for a more appropriate methodology in the area of similar system development.

The Malaysian Space Agency (ANGKASA), with cooperation of the Ministry of Education of Malaysia, has organized the Astronomy Workshop for Primary and Secondary School Teachers since 2008 at the National Planetarium. The workshop was organized to provide science teachers with basic knowledge of astronomy in accordance with the school syllabus, with the hope that they can acquire sufficient knowledge in the field of astronomy to enhance their teaching activities in school. In this workshop, teachers will be introduced to night sky simulations in our space theater, a planetarium show, daytime and night time observation activities, hands on activities, and visits to the planetarium's observatory and exhibition gallery. Besides this, in the workshop they will share teaching experience with planetarium staff. Educational materials are also distributed to all the teachers as reference for their teaching. In this paper presentation, we would like to show how the National Planetarium plays an important role to help teachers in teaching astronomy in schools.

A Lunar observatory not only provides ideas and experiences for space settlements from the Moon to Mars, but also puts the telescope in an optimal position to compete with space telescopes. Earth observation on the Moon's surface has the advantage of no atmospheric scattering or light pollution and is a stable fuel-free observation platform, allowing all longitude and latitude of the Earth to be observed for a month. Observing the entire globe with a single observation instrument, which has never been attempted before, and calculating the global albedo will significantly help predict the weather and climate change. Spectropolarimetric observations can reveal the physical and chemical properties of the Earth's atmosphere, track the global distribution and migration path of aerosols and air pollutants, and can also help detect very small space debris of which the risk has increased recently. In addition, the zodiacal light, which is difficult to observe from Earth, is very easy to observe from the lunar observatory, so it will be an opportunity to reveal the origin of the solar system and take a step closer to understanding the exoplanet system. In conclusion, building and developing a lunar observatory will be a groundbreaking study to become the world's leader that we have never tried before as a first step in expanding human experience and intelligence.

Korea Astronomy and Space Science Institute (KASI) has been developing a next-generation coronagraph (NGC) in cooperation with NASA to measure the coronal electron density, temperature, and speed using four different filters around 400 nm. To demonstrate technology for the measurement through the 2017 total solar eclipse across the USA, KASI organized an expedition team to demonstrate the coronagraph measurement scheme and the instrumental technology. The observation site was in Jackson Hole, Wyoming, USA. We built an eclipse observation system, so-called Diagnostic Coronal Experiment (DICE), which is composed of two identical telescopes to improve a signal to noise ratio. The observation was conducted with 4 wavelengths and 3 linear polarization directions according to the planned schedule in a limited total eclipse time of about 140 seconds.Polarization information of corona from the data was successfully obtained but we failed to get the coronal electron temperature and speed information due to a low signal-to-noise ratio of the optical system. In this study, we report the development of DICE and observation results. TSE observation and analysis by using our own developed instrument gave an important lesson that a coronagraph should be carefully designed to archive the scientific purpose. This experience through TSE observation will be very useful for a success of NASA-KASI joint missions called the Balloon-borne Investigation of the Temperature and Speed of Electrons in the Corona (BITSE) and COronal Diagnostic EXperiment (CODEX).

The Korea Astronomy and Space Science Institute (KASI) has been developing a next-generation coronagraph (NGC) in cooperation with NASA to measure the coronal electron density, temperature, and speed simultaneously, using four different optical filters around 400 nm. KASI organized an expedition to demonstrate the coronagraph measurement scheme and the instrumental technology during the 2017 total solar eclipse (TSE) across the USA. The observation site was in Jackson Hole, Wyoming, USA. We built an eclipse observation system, the Diagnostic Coronal Experiment (DICE), composed of two identical telescopes to improve the signal-to-noise ratio. The observation was conducted at four wavelengths and three linear polarization directions in the limited total eclipse time of about 140 seconds. We successfully obtained polarization data for the corona but we were not able to obtain information on the coronal electron temperature and speed due to the low signal-to-noise ratio of the optical system and strong emission from prominences located at the western limb. In this study, we report the development of DICE and the observation results from the eclipse expedition. TSE observation and analysis with our self-developed instrument showed that a coronagraph needs to be designed carefully to achieve its scientific purpose. We gained valuable experience for future follow-up NASA-KASI joint missions: the Balloon-borne Investigation of the Temperature and Speed of Electrons in the Corona (BITSE) and the COronal Diagnostic EXperiment (CODEX).
