We have carried out a follow-up study on the students who have participated or are going to participate in either the International Astronomy Olympiad (IAO), the Asia Pacific Astronomy Olympiad (APAO) or the International Olympiad on Astronomy and Astrophysics (IOAA) from 2002 to 2011. The survey questionnaires returned from ten high school students including five who are to participate in 2011 as well as fourteen college students have been analyzed in various aspects of their backgrounds and personal characteristics. In family life, their parents tend to have high educational background along with high expectations for their children. In regard to the academic environment, most students express a general satisfaction in school life, including their relationship with teachers and classmates. In personal characteristics, they describe themselves as inquisitive, perseverant, competitive, creative, self-motivated and goal-oriented, in addition to many other traits. Most students have a strong interest in astronomy which usually begins in middle schools through exposure to astronomy books. On top of it, the astronomy olympiad has provided them with an opportunity to strengthen their self-esteem, problem-solving ability and conviction about scientific careers. Accordingly, the experience in astronomy olympiad has led a considerable number of students to continuously studying in astronomy related fields or otherwise in other science and engineering areas. In conclusion, the astronomy olympiad plays such an important role that it can make a significant contribution to astronomy as well as science in general by having positive impact on the potential career path of its participants.

The acousto-optical spectrometer is designed by using 1 GHz bandwidth acousto-optic deflector for radio signal analysis. This system is a high resolution wide band spectrometer which uses I GHz bandwidth and a total of 2,048 channel charge coupled device. When we measured the spectrums of signals deflected by acousto-optical spectrometer, we confirmed the stability of the total system by repetitive observations of the same frequency, and each part of the system worked well. We installed this system onto 60 cm radio telescope, and observed 12CO(J= 1 ∼0) emission lines around CRL 2688, IRC 10216 and NGC 5005 Galaxy center. We could observe effectively very narrow band width radio spectrum as well as wide band radio spectrum. We also confirmed high sensitivity and resolution in observation of 12CO(J-10) omission line of NGC 5005 Galaxy center which is a weak signal. 우주전파의 신호를 관측하기 위한 1 GHz대역의 음향광학 전파분광기를 설계.제작하였다. 이 전파분광기는 다중채널 방식의 신호의 세기가 미약한 우주 전파신호를 분석하기 위한 초고감도의 전파 분광기로, 관측되는 스펙트럼의 모양을 상세히 측정할 수 있는 전파분광기이다. 주파수 분해능과 광대역 주파수 성분을 포함하는 이 음향광학 전파분광기의 광원(optical source)으로는 He-Ne 레이저를 사용하였고, 1 GHz에서 2 GHz까지의 대역폭을 갖는 광대역 GaP 광펼향 소자를 사용하였으며, 광신호 검출을 위해 2,048 채널의 CCD를 사용하였다. 전파망원경을 통해 우주전파신호인 CRL 2688, IRC 10216 그리고 NGC 5005 은하 중심의 12CO(J= 1 ~0) 분자선(molecular line)을 관측한 결과, 광대역의 특성을 가지며 주파수 분해능이 양호함을 확인하였다.

A number of middle and high school students are selected at the Korea Astronomy Olympiad (KAO) in every year. In the first stage of the selection, the resume, school transcript, and recommendation letters from teachers are referred. In the second stage, after video lectures and weekend observation classes, students are tested with on-line homeworks, and interviewed through internet. For 118 students who have gone through the second stage of the 2012 KAO, we have conducted a questionnaire survey, which asks the students the motivation and preparation for the KAO. The survey has also included inquiries for the selection process and education program of the 2012 KAO; the replies will be used as feedbacks for the next year's KAO. The survey has revealed that the first stage worked well, while the second stage needs to be improved in terms of fairness and objectivity. We have found that most students received private tutorings for the KAO, so we suggest efforts should be made for students to be able to prepare the KAO without receiving private tutorings.
