This study aims to develop two science education programs using Angbuilgu and ancient astronomical data, are Korean astronomical heritage, and explore its educational possibility through the pilot application. Considering the TSK compositional characteristics of Angbuilgu and ancient astronomical data, linkage with science curriculum, and linkage with NOS, Angbuilgu was developed as a hands-on activity for elementary school students and ancient astronomical data as a science inquiry activity for middle and high school students. The educational availability of the developed program was confirmed by pilot application to elementary and high school groups. Through the Angbuilgu activity, the students refined their conceptual knowledge by correcting misconceptions about the solar motion by season and then confirmed the possibility of connection with the concept of the celestial coordinate system. Students recognized the scientific value of Angbuilgu and understood the nature of interactions STS. In the ancient astronomical data activity, students experienced inductive and deductive inquiry methods and utilized various information and strategies. Through the activities, students improved their scientific understanding and attitude towards TSK.

The purpose of this study was to find the effect of the astronomical learning program using SGIM on metacognition and science process skills in the elementary scientific gifted students. For this purpose, this research developed the astronomical learning program using SGIM. This program was totally consisted 9 lessen. there was 6 part in this program. It contained select the subject and small grouping (step 1-2), planing inquiry (step 3), doing inquiry (step 4-6), making a report (step 7), announcing (step 8), evaluation (step 9). To find the effect of the astronomical learning program using sgim on metacognition and science process skills in the elementary scientific gifted students. 20 participants was selected. These students were attended at a scientific gifted class (3rd grade) of an elementary school located in Ulsan. First, metacognition test and science process skills test was used to find the effect of the astronomical learning program using SGIM. And the results were analyzed by SPSSWIN 18.0. The results of this study were as follows. First, the astronomical learning program using SGIM was a positive effects on metacognition of the elementary scientific gifted students (t=3.371, p=.001). Second, the astronomical learning program using SGIM was a positive effects on science process skills of the elementary scientific gifted students (t=3.104, p=.021). According to this research, the astronomical learning program using SGIM was verified to improve metacognition and science process skills on the elementary scientific gifted students. It will be contribute on the curriculum construction of the gifted school or gifted class.

The purpose of this study was to find out the effect of the Astronomical Learning Program Using IIM on Science Process Skills and Scientific Attitudes in the elementary scientific gifted students. For this purpose, this research developed the Astronomical Learning Program Using IIM. This program was totally consisted 7 lessen. There was 7 part in this program. It contained Select the subject (step 1), The aim settings (step 2), Collect the data (step 3), Doing inquiry (step 4), An aim evaluation (step 5), Making a report (step 6), Announcing (step 7). To find the effect of the Astronomical Learning Program Using IIM on Science Process Skills and Scientific Attitudes in the elementary scientific gifted students. 20 participants was selected. These students were attended at a scientific gifted class(3rd grade) of an elementary school located in Ulsan. First, Science Process Skills test and Scientific Attitudes test was used to find the effect of the Astronomical Learning Program Using IIM. And the results were analyzed by SPSS WIN 18.0. The results of this study were as follows. First, the Astronomical Learning Program Using IIM was a positive effects on Science Process Skills of elementary scientific gifted students (F=4.920, p=.021). Second, the Astronomical Learning Program Using IIM was a positive effects on Scientific Attitudes of the elementary scientific gifted students (F=11.244, p=.001). According to this research, the Astronomical Learning program Using IIM was verified to improve Science Process Skills and Scientific Attitudes on the elementary scientific gifted students. It will be contribute on the curriculum construction of the gifted school or gifted class.

The purpose of this study was to find the effects of RSM-based astronomical observation program about Astronomical Spatial Concept and Self-Directed Learning for the Scientific Gifted Students. For this purpose, this research developed RSM-based astronomical observation program. This program was totally consisted 10 lessen. there was 3 part in this program. It contained Preparation Stage (step 1-2), Observation Stage (step 3-8), Clean up Stage (step 9-10). To find the effects of RSM-based astronomical observation program on Astronomical Spatial Concept and Self-Directed Learning for Scientific Gifted Students. 20 participants was selected. these students were attended at a scientific gifted class(5th grade) of an elementary school located in Ulsan. First, Astronomical Spatial Concept was used to find the effect of the Astronomical Observation program based RSM. And the results were analyzed by SPSSWIN 18.0. The results of this study were as follows. First, RSM-based astronomical observation program was a positive effects on Astronomical Spatial Concept of the Scientific Gifted Students (t=3,875, p=.001). Second, RSM-based astronomical observation program was a positive effects on Self-Directed Learning of the Scientific Gifted Students (t=5.783, p=.000). According to this research, RSM-based astronomical observation program was verified to improve Astronomical Spatial Concept and Self-Directed Learning on the Scientific Gifted Students. It will be contribute on the curriculum construction of the gifted school or gifted class.

A high performance computing cluster for astronomical computations has been built at Korea Astronomy Observatory. The 64 node cluster interconnected with Gigabit Ethernet is composed of 128 Intel Xeon processors, 160 GB memory, 6 TB global storage space, and an LTO (Linear Tape-Open) tape library. The cluster was installed and has been managed with the Open Source Cluster Application Resource (OSCAR) framework. Its performance for parallel computations was measured with a three-dimensional hydrodynamic code and showed quite a good scalability as the number of computational cells increases. The cluster has already been utilized for several computational research projects, some of which resulted in a few publications, even though its full operation time is less than one year. As a major resource of the $K^*Grid$ testbed, the cluster has been used for Grid computations, too.

In this study, we collected articles published in the Publication of the Korean Astronomical Society (PKAS) from 1984 to 2021, and performed quantitative analyses of their various aspects. PKAS is the journal where authors can publish research papers in Korean as well as English. It seems to have an advantage of the better accessibility to all people than other astronomy journals in English only. From 1984 to 2000, the number of articles published in PKAS has been steadily increased. From 2000, the number of published articles showed a tendency to decrease slightly every year. After 2010, the number of articles in PKAS has shown a sharp decline until now. Interestingly, in this period it is found that the topics published articles became various, in particular, many articles concerning historical astronomy began to be published. PKAS was selected as an accredited journal in 2018. This is a very positive situation, and we think the future direction of PKAS is encouraging. Considering these circumstances, the PKAS is suggested to reflect ideas of "interdisciplinary fusion" and "diversity" in publishing articles in the journal for its promising future.
