The study of old star catalogues provides important astrometric data. Most of the researches based on the old star catalogues were manuscript published in Europe and from Arabic/Islam. However, the old star catalogues published in East Asia did not get attention. Therefore, among the East Asian star catalogues we focus on a particular catalogue recorded in a Korean almanac. Its catalogue contains 277 stars that are positioned in a region within 10? of the ecliptic plane. The stars in the catalogue were identified using the modern Hipparcos catalogue. We identified 274 among 277 stars, which is a rate of 98.9 per cent. The catalogue records the epoch of the stars' positions as AD 1396.0. However, by using all of the identified stars we found that the initial epoch of the catalogue is AD 1363.1 ± 3.2. In conclusion, the star catalogue was compiled and edited from various older star catalogues. We assume a correlation with the Almagest by Ptolemaios. This study presents newly analysed results from the historically important astronomical data discovered in East Asia. Therefore, this star catalogue will become important data for comparison with the star catalogues published in Europe and from Arabic/Islam. [ABSTRACT FROM AUTHOR]

This study examined the differences of the nature of science (NOS) conceptions portrayed by preservice teachers in Korea (N = 42) and the United States (N = 50). We conducted a survey of preservice elementary science teachers' NOS conceptions followed by interviews in both countries to further investigate their viewpoints. The NOS domains of this investigation were Relativism versus Positivism, Inductivism versus Deductivism, Contextualism versus Decontextualism, Process versus Content, and Instrumentalism versus Realism. Findings indicated that preservice elementary science teachers' images of science were dominated by Relativism and Process in both countries. The conceptions of preservice teachers were different, however, in Inductivism versus Deductivism, Contextualism versus Decontextualism, and Instrumentalism versus Realism. Implications of these findings are discussed at the end of this article. [ABSTRACT FROM AUTHOR]
