  • The objective area of this study is a private house of common people at SimPori in the riverside area of OsipCheon. This area is the upriver of OsipCheon, and it was distributed at the 田-shaped House and the Dureong House with the composition of GuDl. Owing to the frequent interchange of AnDong and BongWha in the Young Seo district, the Kyup House and the SaBang House mixed with the 田-shaped House with GuDl of the YoungDong district. So the form of Folk House at this area is Dureong House. The Folk House of the seaside of SamCheok City is a compromised type among the 田-shaped House of GuDl in the north district and with MaRu in the south district, and introduced an indeterminate MaRu formed in the GaGokCheon area.

  • We investigate the life of Lee Cheon (1376-1451) who was closely connected with astronomy during the reign of King Sejong of the Joseon dynasty. Lee Cheon is widely regarded as one of the outstanding scientists of King Sejong's period. However, his contributions to the development of the astronomy during the period have not been enlightened. Based on the historical records on the life and achievements of Lee Cheon, mainly referring to the Joseonwangjosillok (Annals of the Joseon Dynasty), we address three important points. First, Lee Cheon was a distinguished administrator who filled various government posts. Second, he was a supervising engineer in public works and metal smelting during his position in military. Third, he was a scientific technician and manufactured precision equipment such as the metal movable type sets. By virtue of these aspects, Lee Cheon was taken into confidence by King Sejong on the Ganui-dae project (i.e., manufacture various astronomical instruments and construct their platform in order to make a calendar suitable for Joseon). During the period of this project, Lee Cheon not only supervised the construction of the Ganui (simplified armillary sphere) and Ganui-dae (platform for astronomical instruments) but also participated in the production of the astronomical instruments such as Gyupyo (Gnomon) and Honcheonui (Armillary Sphere). In conclusion, we regard Lee Cheon as one of the astronomers who led a great advance in astronomy during King Sejong's era.
