China and Korea have a long history of star charts, dating from the prehistoric period. Historically, Korean astronomy has been deeply influenced by China over the last two thousand years, particularly on constellation system. Therefore, Chinese and Korean traditional star charts have many similarities in terms of shape of constellation, number of star, and so forth. Korean star charts, however, have lots of unique characteristics distinguishing from Chinese ones, such as, size of star and position of constellation. Overall knowledge of the Chinese star chart is required to study the Korean star chart. In this paper, I focus on introducing selected star charts in China and Korea. Although this review is very limited, I hope that this paper is helpful in research in the field of historical astronomy.

This paper discusses the two major Korean Shakespeares, Kim Myung-Gon's King Uru and Oh Tae-Suk's Romeo and Juliet, in answer to the request made by Stanley Wells at the 2006 Craiova Shakespeare Festival: theatre practitioners should have 'something worthwhile to say' before they put something of their own in Shakespeare's place. Kim and Oh, who have won international acclaim for their adaptations, present 'something worthwhile to say' by bringing Shakespeare to the world in the light of traditional Korean astronomy. The star map named 'Cheonsang yeolcha bunya jido,' which was founded in 1395 and designated as the No. 228 National Treasure of Korea in 1985, is employed as a means by which to bring 'something worthwhile to say' to Shakespeare: it works as a symbol of the cosmic power to restore the divided kingdom and strengthen the kingly power in King Uru; its concept of Hyeonmu, the northern seven lodges of the twenty-eight constellations, is associated with the deaths of not only the lovers but also the whole members of their families in Romeo and Juliet. It is representative of the sunny, light and fiery force of yang in King Uru, whereas of the shady, dark and watery force of yin in Romeo and Juliet. Thus these two productions differ in their approaches, although they make the relevance of traditional Korean astronomy recognizable by redrawing the bounds of Shakespearean tragedy genre: King Uru reminds us of the human capacity for self-recovery, while Romeo and Juliet the human capacity for self-destruction.

There were two books on astronomy published in 1908. One is "Astronomy (天文學)" written by Jeong, Yeong-Taek (鄭永澤, 1874 ~ 1948), an educator. The other is "Introduction to Astronomy(텬문략 )" written by William Martyn Baird (裵偉良, 1862 ~ 1931), an American missionary. It was known that these two books were translated into Korean as astronomical textbooks of the Korean Empire. We investigated the life of translators, the motivation of writing textbook, and the translators' specialty in astronomy. We also compared the two books in terms of content, orthography of terminology, scale of units, and so forth. We suggest that these books were really utilized as textbooks of astronomy in the modern school in the early $20^{th}$ century in Korea. We also conclude that in astronomy education these two textbooks bridged the gap between the traditional Chinese astronomy of the middle age and modern astronomy from the West.

우리의 현실에 부합하는 과학문화를 창출하기 위해서는 과학기술의 외래성을 극복하고 전통과의 단절을 넘어설 필요가 있다. 이를 위해 전통과학의 대표적인 분야인 천문학을 통해 우리 전통과학의 특징을 이해하고 바람직한 과학문화 형성의 가능성을 모색하고자 한다. 이를 위해 먼저 고대 문명에서 처음 등장하는 천문학의 일반적인 특징을 살펴서 전통 천문학에는 과학의 한 분야로서 천문학적 지식과 함께 여러 문명마다 각기 다른 고유한 문화적 요소가 들어있다는 점에 주목한다. 천문학의 여러 세부 분야 중에서 사람들의 실생활과 밀접하게 연관되어 있으며 문화적 차이를 잘 드러내 주는 것은 시간의 과학이라고 할 수 있는 달력과 역법이다. 모든 고대 문명에서 해와 달의 운행을 기준으로 삼아 시간을 표현했지만, 시간을 구체적으로 어떤 방식으로 표현할 것인가 하는 문제는 각각의 문화마다 서로 달랐다. 그 결과 달력에서 음력과 양력 그리고 음력과 양력의 특성을 모두 가지고 있는 태음태양력 체계가 나타났다. 우리나라를 비롯한 동아시아에서는 태음태양력을 사용했는데, 동아시아에서 달력은 서양 세계와는 달리 복잡하고 정교한 천문학적 작업인 역법에서 도출된 것이다. 한편, 민간생활을 잘 보여주는 세시풍속에서도 태음태양력의 특징을 분명하게 찾을 수 있지만, 또한 세시풍속에는 이른바 미신적인 내용이 많이 들어 있기도 하다. 이런 점 때문에 우리의 달력 체계를 비과학적인 것이라고 오해하거나 나아가 전통과학 전반에 대해 과학적인 측면이 결여되어 있다고 의심하기 쉽다. 하지만 동아시아의 달력과 역법을 제대로 이해함으로써 우리 전통 속에 과학적인 측면이 분명하게 존재했다는 점을 확인할 수 있으며, 이것이 오늘날 과학기술의 외래성을 극복하고 전통과의 연결점을 찾을 수 있는 고리가 될 것이다.

Traditional bound abrasive grinding leaves the machine marks and subsurface damages ranging from 1 to few tens microns ms in height. These are removed typically by subsequent craftmen-based loose abrasive lapping, polishing and figuring. Using the multi-variable regression technique, we established a new automated grinding process control method for the removal of loose abrasive lapping from the traditional fabrication process.

Neutrino astronomy is now possible as the technology to detect neutrinos has been advancing. Current and planned neutrino-detecting facilities can be operated as a conventional telescope because they can measure the direction toward the celestial sources as well as their physical properties like energy. Together with gravitational wave, neutrino astronomy opens a new field of astronomy, often called, multi-messenger astronomy, which also involves "traditional" electro-magnetic-wave-detection-based astronomy. Expecting that Korean Neutrino Observatory (KNO) will be one of the best neutrino observatories when it is constructed, a group of Korean astronomers and astrophysicists formed a working group and began to investigate possible astronomical neutrino sources that could be detected by KNO and other neutrino observatories. This talk presents the recent activities of the working group and introduces the list of possible neutrino sources.

On-The-Fly (OTF) observation method is developed for the efficient use of 6 M radio telescope at Seoul Radio Astronomy Observatory (SRAO). This technique, in which data and information of antenna position are recorded synchronously while driving a telescope regularly and rapidly across a field, provides more efficient use of telescope time and better calibration of the acquired data than the traditional point-to-point observation method does. For the realization of the method, we (1) added RT-Linux modules to the existing operating system, (2) replaced digital voltmeter with voltage-to-frequency converter, and (3) modified many SRAO observation programs. By observing Moon and G78.2+2.7 using this method and comparing them with previous observations, we verify the successful operation and efficiency of the OTF observation mode.

We report about the constellations discovered in Ara-Gaya Malisan tomb 13 of late 5th century. In December 2018, constellation-shaped grooves were newly found on the ceiling of the tomb 13 of the Ara-Gaya (42-532 CE.) polity in Haman(咸安). The tomb 13 is located at the top/center of the Malisan and is one of the largest burial mounds. Grooves were found in one of the slabs of the grave cover-stone (160 ∗ 80~60cm). The total number of grooves are 134 and each groove has a diameter of 1.5~4.0 cm. The grooves were made by pecking or grinding. From the preliminary study, we identified these grooves with traditional constellations such as 房, 心, 尾, 箕, 斗, which correspond to Scorpius and Sagittarius of modern constellations near the Milky Way. It shows that advanced astronomy also existed in Ara-Gaya tomb while star charts were painted in Goguryeo tombs. This carries great importance in studying the development and exchange of astronomy in the Korean Peninsula.

The origin of the Korean Screen Planisphere with both Traditional and New Star-Charts, made by Korean Astronomers in the Royal Astronomical Bureau of the Joseon Dynasty by adopting the knowledge of the European astronomy, is investigated by analyzing its inscriptions and star charts. The considerations on both the changes in notations or representations of names of asterisms and the naming taboos used in the Old-style planisphere imply that the star-chart is originated from either the Sukjong-Stele-Replica of Cheonsang-Yeolcha-Punyajido(天象列次分野之圖). The New style planisphere is just the reproduction of Huangdao-congxingtu (黃道總星圖), with the exception of the non-Chinese-traditional stars. The Huangdao-congxingtu was made in 1723 CE by Ignatius K$\ddot{o}$gler who was a Jesuit missionary and worked for the Bureau of Astronomy (欽天監) in the Qing Dyansty. I find that the star chart was imported in 1742 CE from the Qing by An Gukrin (安國麟) who was an astronomer in the Royal Astronomical Bureau of Joseon. The chart became model for the screen star-chart made in 1743 CE and now housed in Bopju temple. I found that the inscriptions are extracted from the sentences in both Xinzhi Lingtai Yixiangzhi (新製靈臺儀象志) and Qinding Yixiangkaocheng (欽定儀象考成). Korean historical records in either Daily Records of the Royal Secretariat of the Joseon Dynasty (承政院日記) or Annals of the Joseonn Dynasty (朝鮮王朝實錄) show that Xinzhi Lingtai-Yixiangzhi was imported from the Qing Dynasty in 1708 CE, and the Qinding Yixiangkaocheng was imported in 1766 CE. Thus, the Korean Screen Planisphere with both Old and New Star-charts was certainly made after 1766 CE.
