We study a manuscript that includes 28 oriental constellations in the flags of barracks in Gangjin. According to the Joseon Chronicles, the constellation flags in the manuscript are thought to have originated from Seon-Pil Kim (金善弼) who first made 28 constellation flags for the barracks in 1878 during the Joseon Dynasty. Seon-Pil Kim was a commander and he used the 28 constellation flags for communications in a military camp. The flags also contain 28 animals and letter-like symbols with constellation maps. We examine the constellation maps in flags in terms of shapes and number of stars, and compare them with those of constellations in the Korean and Chinese star charts such as CheonSangYeolChaBunYaJiDo (天象列次分野之圖), Joseon-Butienge (朝鮮步天歌), Suzhou (蘇州) Star Chart, and Tang-Butiange (唐步天歌). Finally, we found that the shape of constellations in the flags might be similar to those in the Chinese Tang-Butienge. We also found several errors such as the shape, connecting pattern, and number of constellations drawn in the flags. It seems that the constellation flags were unofficially used in military camps in the late Joseon dynasty. Meanwhile, the 28 constellations are divided into four groups and each group has its own color and direction. We suppose that the constellation flags might represent the positions of military camps and each group of flags has their own color based on their cardinal points.

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.

건륭(乾隆) 3년(1569)에 제작된 일본 교토(京都) 고려(高麗)미술관 소장의 <치성광여래강림도(熾盛光如來降臨圖)>는 조선 전기 치성광여래강림도상으로는 현재 유일한 것이다. 보존상태가 양호하여 작품 내 거의 모든 도상과 旁題銘의 판독이 가능한 상태이며 화기 부분도 크게 손상되지 않았다. 작품은 홍색을 올린 바탕에 금니화로 $84.8{\times}66.1cm$의 비교적 작은 크기의 불화이다. 이 작품은 화면 중앙 치성광여래를 중심으로 하여 존명이 적혀 있지 않은 양대보살, 십일요(十一曜)와 천황성(天皇星), 옥황상제(玉皇上帝) 및 이십팔숙(二十八宿), 황도십이궁(黃道十二宮), 삼태육성(三台六星), 북두칠성(北斗七星) 등이 배치되어 조선시대 성수신앙의 일 단면을 살펴볼 수 있는 좋은 자료가 되고 있다. 이 작품의 도상은 고려본 치성광여래강림도와 같은 계열이기는 하지만 일부 성수에서 자미성, 천황성과 같은 도교적 성수가 등장하고 여래형 북두칠성 등 의미있는 도상변화가 나타나고 있어 조선시대 성수신앙의 전개과정을 알 수 있다. 본 <치성광여래강림도>는 주요 권속으로 십일요가 중심이 되긴 하였으나 계도성이 생략되고 월패성도 중심에서 벗어나 있어 십일요 구성에 대한 개념은 약화되고 있음을 알 수 있었다. 그리고 자미성, 옥황대제, 천황제와 같은 도교의 성수신이 포함되면서 도교와 불교 성수신의 뚜렷한 구분이 없어지는 현상도 나타나고 있다. 이 불화에 나타난 이십팔수의 별자리 그림은 중국의 치성광여래도와는 달리 우리나라 천문도의 별자리 그림을 정확히 반영하고 있어 성수신앙의 독자성도 엿볼 수 있었다. 북두칠성과 칠원성군을 동시에 그려서 칠성신앙을 강조한 사실은 칠성신앙의 중요도가 점차 높아지고 있음을 반영하는 것으로 해석할 수 있다. 또한 작품의 제작 수준으로 보아 대시주 '최씨도령(崔氏徒令)'은 유복한 계층의 어린아이일 가능성이 높아, 이 작품이 자손의 연명(延命), 소재(消災) 등을 기원하면서 제작된 호신부적 성격의 불화였을 것으로 추정해볼 수 있었다.

Gaecheonjeol is the National Foundation day of Korea when people hold a harvest ceremony. Nowadays, two representative harvest ceremonies of Korea are performed at Mt. Mari (摩利山) and Mt. Taebaek (太白山) on Gaecheonjeol (October 3rd). We study 28 flags with constellations appearing in the ceremony of Mt. Taebaek. These flags are lying in the outer of the circular stone wall during the ceremony. They represent an oriental heavenly star chart. We examine the shape, the connecting-pattern, the name, and the number of constellations drawn in the flags, and find several errors, such as, a wrong position, a typo of name, an irregular size, an omission, and so forth. Traditionally, the 28 oriental constellations are usually divided into four groups and each group has its own colour for each direction: Blue (E), Black (N), White (W), and Red (S). For the constellation flags in Mt. Taebaek, the colour of the flags is painted based on geographical directions, but the constellations are arranged followed by the direction of the celestial sphere. Thus, constellations in the northern and southern parts are counterchanged. Finally, we suggest some possible criteria for constellation map of the flags in this paper. CheonSangYeolChaBunYaJiDo (天象列次分野之圖) and CheonMunRyuCho (天文類抄) can be essential references for correcting constellations drawn in the flags of Mt. Taebaek.

전라남도 강진에서 발견된 영기(令旗)라는 책에는 병영에서 사용된 별자리 깃발에 관한 기록이 남아있다. 영기는 군중에서 군령(軍令)을 전달하기 위해 사용한 것으로 고종 대에 이르러 깃발에 28수(宿) 별자리를 처음으로 사용한 것으로 알려져 있다. 승정원일기와 일성록에 의하면 군영에서 사용한 28수 별자리 깃발은 1874년 중앙관 진무사(鎭撫使)의 수장이었던 김선필(金善弼)이 처음 만들어 사용한 것으로 기록되어 있다. 본 발표에서는 국내에 처음 보고된 28수(宿)가 그려진 영기를 소개하고 영기의 별그림을 한국과 중국의 전통 성도와 비교한 내용을 발표하고자 한다. 영기에는 28수 별자리 외에도 28 동물과 기하학적 문양이 그려져 있는데 이에 대해서도 간단히 소개하고자 한다. 영기 별그림은 실제 성도와 비교해 많은 오류가 확인되는데 이를 교정하여 새롭게 도안한 별자리 깃발도 함께 소개하고자 한다.

Chang Hyon-Gwang(1554-1637) compared the relationship between Ipam and the 28 places with that of the Polestar and 28 constellations. And he considered the ipam to be the core of the universe. This paper aims to identify the meaning of christening to the places for him. I analyzed contents of Chang's , and which preserved the traditional view of the site and writings. As a result, christening to the natural places mean that promote the environment for housing. It is a architecture by itself.

When quadrature error exists, the shape of the M-ary phase shift keying (MPSK) signal constellation becomes skewed-elliptic. Each MPSK symbol takes on a different symbol error probability (SEP) value. The analytical results presented thus far have been derived from studies which examined the SEP problem assuming that the SEP of each MPSK symbol is equally likely; therefore, those results should not be treated as offering a complete solution. In this letter, we present a new and more complete solution to the SEP problem of MPSK by relaxing the above assumption and finding the expressions for the average as well as individual SEP in the presence of quadrature error.

The Hun-Min-Jeong-Eum(訓民正音) has been created under the political purpose that is to unite politics and cultures through a philosophical harmony of the confucianism as well as the Buddhism under the periodical circumstance that includes the change of a dynasty and a revolution in culture. The creating work has been greatly affected by the theoretical divination, that is the confucian ideas of North-Song dynasty which has been highly elaborated in those days. The shape of the characters of the Hun-Min-Jeong-Eum(訓民正音) has been influenced by the ancient letters existing at the time (especially Ga-Rim-To 加臨多), it has been throughly readjusted and recreated based on the philosophy. The consonant uses the Three-Pillars(三才)(ㅇ, ㅁ, △) in the style of the five elements and each velar-lingual-labial-dental-guttural sounds (牙舌脣齒喉音) is applicable to five elements also a 'ㅇ' is equivalent to the heaven, a 'ㅁ' to the earth. a '△' to the man. The vowel uses the five elements of ㅗ(water). ㅏ(wood), ㅜ(fire), ㅓ(metal), ㆍ(five-soil), ─(ten-soil) in the style of the Three-Pillars(三才) of ㆍ, ㅡ, ㅣ and the first created letters(初出字), and the secondary created letters(再出字) each can be attached to the eight trigrams(八卦). The consonant has 17 letters and the vowel has 11 letters, therefore the total number of the letters is 28. and those are equivalent to the 28 constellation(二十八宿) of the astronomy. Contrary to the underlying principle that has been applied during the time of the creation of the letters, when the consonant and the vowel are used, the consonant refers to the heaven (天), and the vowel refers to the earth(地). a consonant take a part in making a point on the starting place of the pronounce, a vowel take a part in the keeping the energy to the end.

Objectives : This research aimed to 1) analyze the true meanings of the chapter, 'Wigi Haeng (Wei Qi Xing), the movement of guard qi' in Youngchu (Ling Shu) from the point of view of ancient Chinese Astronomy, 2) calculate the speed of Wigi over 24 Chinese seasons, 3) analyze the true meaning of daytime and nighttime in the chapter. Methods : 1) The chapter 'Wigi Haeng' was analyzed using concepts of ancient Chinese astronomy, 2) the records of angular distances of 28 constellations in the Book of Han (Han Shu) were used to analyze the meanings, and 3) the records of lengths of daytime and nighttime in the Book of Hou Han (Hou Han Shu) were used to calculate the speed of Wigi. Results : 1) The author of the chapter 'Wigi Haeng' did not consider the irregularity in the angular distances of the 28 Chinese constellations (Su). 2) The commentary in the Huangjenaegyong Taeso (Huang Di Nei Jing Tai Su) about the constellations in the chapter is correct. 3) The speed of Wigi changes in daytime and nighttime depending on the seasons. 4) When the speed of Wigi increases in daytime, the speed in nighttime decreases, and vice versa. 5) The beginning of daytime in 'Wigi Haeng' is not the time of sunrise but the time of dawn (2.5 Gak before sunrise). The nighttime ends 2.5 Gak after sunset. Conclusions : 1) The chapter 'Wigi Haeng' demonstrates the ancient astronomical point of view on the universe and the movement of Wigi. The speed of Wigi is variable. 2) This chapter does not address the irregularity in the angular distances of the 28 Su. 3) More research is needed on the meaning of daytime and nighttime in 'Wigi Haeng'.
