  • The purpose of this study is to investigate the possibility of introducing the history of science in modern Korea into elementary education. Although there are many studies on applying a history of science to science education, they do not pay attention to the history of science in modern Korea. I survey research papers on the history of science in modern Korea and science education based on a history of science, and elementary science textbooks in Korea, Japan and the US. When we apply the history of science in modern Korea into elementary education, elementary students will recognize science has close relations to Korean culture and history and they will develop the familiarity with science. I show there are 3 ways using the history of science in modern Korea in elementary education: 1) Applying Korean scientists' research contents to science education, 2) Measures to evaluate Korean scientists correctly, 3) Materials for science education programs for gifted elementary students.

  • As a governmentally approved domestic entity for Space Situational Awareness, Korea Astronomy and Space Science Institute (KASI) is developing and operating an optical telescopes system, Optical Wide-field PatroL (OWL) Network. During the test phase of this system, it is necessary to determine the range of brightness of the observable satellites. We have defined standard magnitude for Low Earth Orbit (LEO) satellites to calibrate their luminosity in terms of standard parameters such as distance, phase angle, and angular rate. In this work, we report the optical brightness range of five LEO Satellites using OWL-Net.

  • We present for the first time the characteristics of upper atmospheric horizontal winds over the Korean Peninsula. Winds and their variability are derived using four-year measurements by the Korea Astronomy and Space Science Institute (KASI) meteor radar. A general characteristic of zonal and meridional winds is that they exhibit distinct diurnal and seasonal variations. Their changes indicate sometimes similar or sometimes different periodicities. Both winds are characterized by either semi-diurnal tides (12 hour period) and/or diurnal tides (24 hour period) from 80-100 km. In terms of annual change, the annual variation is the strongest component in both winds, but semi-annual and ter-annual variations are only detected in zonal winds.

  • The purpose of this study was to compare and analyse the subject organization and teaching units of middle school science curriculums and science textbooks, by studying the organization of subject matter and content scope and level of middle school science subject in South and North Korea. As a result of this study, the composition, scope, and level of content between middle school science textbooks in South and North Korea were similar. However, the study found that science education objectives, separated science curriculum subject organization, economical efficiency weighted format and organization of science subject matter, result-centered experiments, the enlightenment of Kim Ilsung and his son in North Korea science education were very far from the desirable direction of science education. Therefore, the view on level-based curriculum and organization of the science curriculum should be integrated, and preparation of student-centered organization of textbooks and expansion of science-technology-society content is needed before unification. And also, the united Korea science curriculum shouldn't simply compromise or neutralize between middle school science curriculum in South and North Korea. They should make a future-oriented plan for information and globalism society.

  • We carry out 100-GHz band test observations with the newly-constructed KVN 21-m radio telescopes in order to evaluate their performance. The three telescopes have similar performance parameters. The pointing accuracies are about 4" rms for the entire sky. The main beam sizes are about 30" (FWHMs), which is nearly the diffraction limit of the telescopes at the observing frequency (97 GHz). The measured aperture and main-beam efficiencies are about 52% and 46%, respectively, for all three telescopes. The estimated moon efficiency is ~84% for the KVN Tamna telescope. The first sidelobes appear 50" (~1.6${\times}$FWHM) from the main beam centers and the levels are on average -14 dB.

  • This research is aimed to examine the differences through comparative analysis of the Earth Science contents in the science textbooks between Korea and DPRK. The contents of level and scope in science textbooks between Korea and DPRK are analysed by TIMSS frameworks. The results of this research are as follows : 1. The science textbooks of DPRK is lower in quality of paper, printing to that of Korea, and the illustrations, editing design in the textbooks of DPRK are fewer, monochromic and monotonous while those in Korea. 2. The contents of Earth Science in DPRK's science textbooks rank 37.0%, but those of Korea's science textbooks rank 25.5% of the whole textbooks. The learning units related to Earth Science are generally similar to the level and scope in science textbooks between Korea and DPRK. The type of inquire activities in the textbooks of DPRK largely takes on the model experiment, and it was shown that the number of experiments directly made by children is very small compared to Korea' textbooks. 3. There are lots of differences in Earth Science learning terms and predicates used in the textbooks between Korea and DPRK.
