국립청소년우주센터는 전라남도 과학문화확산활동사업으로 하이브리드방식의 천문우주과학교실을 운영하고 있다. 사업은 '소통하는 천체관측 플랫폼'과 '내가 만든 천체사진' 프로그램 두 가지로 운영 중이다. '소통하는 천체관측 플랫폼'은 날씨가 맑은 날 시민이 있는 곳을 찾아가서 천체를 보여주며 인터뷰와 생중계를 하는 것이다. '내가 만든 천체사진 프로그램'은 하이브리드 방식으로 프로그램을 운영하며 기존에 촬영된 천체사진과 원격관측을 이용해서 날씨에 상관없이 천체사진을 제작 할 수 있게 운영된다. 밤하늘의 천체를 안시관측으로만 만족하지 않고 사진관측의 매력을 알려 천문관측의 패러다임을 변화 시킬 수 있도록 운영한다. 또한 천문관측을 값비싼 장비가 있는 곳에서만 가능 한 것이 아니고 장비공유를 통해 천문관측을 할 수 있도록 시스템을 구축했다.

This study analyzed the programs offered in the youth center located in Gyeongsangnam-do Province in accordance with the domains for creative activity. The creative activity, introduced through the 2009 revised national curriculum, puts an emphasis on the experiential activities to enhance the creativity of students. The creativity activity needs to be operated as intended in order to ensure that the students can grow into adults, who have creativity and good personality, by amassing a variety of experiences. For that, various human resources and physical resources of communities need to be utilized efficiently. Thus, this study explored the measures to achieve the original objectives of creativity activity by analyzing the programs - offered by the youth centers in Gyeongsangnam-do Province - based on the scope of creativity activity. The followings are the results of the analysis of 177 programs offered in 12 organizations that came under the three categories (training facilities operated directly by the Education Office, public training centers, culture center) of the youth centers located in Gyeongsangnam-do Province. Autonomous activity' comprised the highest proportion in the youth center programs of the three categories, followed by club activity. The programs associated with the 'career activity' - which most students have the highest expectations in relation to the creativity activity - comprised relatively low proportion. In conclusion, the programs offered by the youth centers in communities need to become more diversified in order to achieve the intended results of creative activity. In addition, the programs associated with the 'career activity', which student prefer the most, need to be operated in a more diversified manner with greater emphasis. Furthermore, the measures should be explored which may increase the involvement of youth education experts of community in the operations of creativity activity.

We will soon complete the installation of 1m telescope at Deokheung Optical Astronomy Observatory (DOAO), National Youth Space Center (NYSC). Before the test observation with NYSC 1m telescope, we present the specs of the 1M telescope and observational conditions of the DOAO site, such as the seeing data at DOAO and the atmospheric extinction coefficients obtained from the observations of standard stars and stellar clusters with 120mm and 150mm refractor in 2014. Since atmospheric extinction coefficients depend on the observational instruments as well as the atmospheric conditions of the site, the improved data with NYSC 1m telescope will be obtained right after the completion of 1M telescope installation. We are planning to invite all astronomers to use 1m telescope for their sciences via regular proposal processes in this year.

During the year 2016 the newly installed NYSC (National Youth Science Center) 1m optical telescope was officially commissioned. Calls for future observational programmes were announced. During test observations we carried out an observational project aimed at follow-up observations of transiting extrasolar planets. To predict future transits we developed the "TransitSearch" code implemented in Python utilizing transit information from the Open Exoplanet Catalogue. During three nights in April and June 2016 we observed planetary transits of HAT-P-3b and TrES-3b. Preliminary light curves of the transit events are presented alongside with best-fit models. From this experience we plan to improve the optical alignment and photometric performance by operating the 1m NYSC telescope in a strongly out-of-focus mode for transit observations.

해시계는 태양의 겉보기 운동을 통해 시간과 좌표계에 대한 이해를 도와주는 도구 중 하나이다. 국립고흥청소년 우주체험센터에서는 지평면 해시계와 수직 해시계를 덕흥 천문대에 설치하였다. 지평면 해시계는 관측자 자신의 그림자로 시각을 알 수 있도록 제작하였다. 관측자가 서는 곳에 아날렘마, 매월 1일의 위치 및 각 절기를 표기하여 균시차를 보정할 수 있게 하였다. 벽면 해시계는 가로 1.8m, 세로 1.8m 크기로 황동 주물제작하여 정남향으로 설치하였다. 눈금의 간격은 15분이며 균시차 보정은 하지 않았다. 두 해시계 모두 실제 센터의 경도에 맞춰 설계했으며 표준시와 시간차이를 보이게 했다. 지평면 해시계와 수직 해시계는 센터를 찾아오는 방문객에게 과학적 호기심을 일으키는 야외 체험전시물의 역할을 할 수 있을 것으로 기대하며 향후 해시계를 활용한 실험체험 프로그램을 통하여 청소년이 시간과 좌표계의 개념을 쉽고 명확하게 이해하는데 도움을 주고자 한다.

Transit event of exoplanet is a good example of observational studies with youth, because the event is geometrically simple and its analysis is essential to astronomical observation. Therefore, we developed the package of data reduction and aperture photometry in Python for educational purpose. In 27 July, we observed the transit event of TrES-3b with the students of "NYSC Space Science Club" program, and presented the Python package, PyPhotW for data reduction and aperture photometry. PyPhotW consists of simple functions for youth to understand the processes easier. Nonetheless, the photometric results of PyPhotW show a good agreement with those of Source Extractor, ${\Delta}m{\sim}-0.01{\pm}0.03$ and $-0.04{\pm}0.08$ for TrES-3b and TrES-5b time-series observations in 27 - 28 July.

This study aimed to explore the current status of playgrounds, children's libraries and youth centers as local community centers in support of children. Its data were collected from reviewing the relevant literature, interviews, surveys and web search. It was found that children's libraries were predominantly located in Seoul and Kyungki provinces. In comparison with other advanced countries, Korea had lower ratios of volumes of books and periodicals per the library user and of a number of staff per the user. It was also found that over a half number of playgrounds was placed in apartment areas. Since 1993, the long-term youth development plan has commenced the construction of various societal infrastructure such as local youth centers, counseling institutes, sex-culture centers and youth cultural zones. Based on these findings, some policy issues were raised.

National Youth Space Center will complete installation of the NYSC 1m Telescope in this year. Before completion of the telescope, we present the software design of JTCS, and the preliminary result of tracking performance by JTCS and mount of the telescope. JTCS currently uses commercial software of the Sky X, for the real-time coordinates of various objects, such as asteroids, comets, and even satellites. In order to guarantee flexibility in CCD detectors, the MaxIm DL software was adopted and JTCS provides auto-guiding and scheduled image-taking with MaxIm DL. We are now stabilizing the telescope mount and JTCS with long-exposure tests, and gathering the preliminary data of tracking performance.

국립고흥청소년우주체험센터는 2014년부터 덕흥천문대에 설치된 SBIG사의 "Seeing Monitor"로 시상을 측정하고 있다. "Seeing Monitor"는 북극성을 대상으로 TDI(Time Delay and Integration) 방식을 적용하여 얻어진 시상을 분 단위로 저장해준다. 따라서 구름이 없는 맑은 날의 분 단위 시상 자료와 주변 환경 정보를 조합하여 시상에 영향을 미치는지 환경 요인을 정량적으로 분석하는 것이 가능하다. 그 첫 단계로 측정된 시상 자료와 기상청의 온도 습도 풍속 자료, 그리고 GFS(Global Forecast System)의 고도별 상층 풍속 자료를 비교하여 기상정보와 시상과의 관계를 분석해보았다. 습도와 바람이 시상에 가장 큰 영향을 주었으며, 지상 풍속 1~2m/s, 습도 75% 이하, 제트기류 풍속은 250km/h 이하 일 때 좋은 시상 값을 얻을 수 있었다. 이를 통해 덕흥천문대에서 기상정보를 통해 시상이 안정적인 날을 예측할 수 있다면, 앞으로 도입될 1m 망원경으로 훌륭한 관측 자료를 얻을 수 있을 것이라 기대된다.
