  • The purpose of present study is to describe the taxonomy and early life history of Korean pomfrets, genus Pampus. Egg diameter varied from $0.83\~1.27mm\;and\;1.05\~1.41mm$ in P. argenteus and P. echinogaster respectively. Larvae of P. echinogaster of 16.5 mm in total length has full number of fin rays and enter the juvenile period. The egg is matured at 185.0 mm in total length in P. argenteus and at 95.5 mm in total length in P. echinogaster. P. echinogaster is ossified from jaw bone at $8.5\~10.0mm$ in to1 length and followed by ossification of vertebrae and visceral skeleton. P. argenteus and P. echinogaster are distinguished by the morphology of jaw, fin and isthmus. In P. argenteus, wavy ridges extends over the upper part of pectoral fin and gill membrane is broadly united to isthmus, while in P. echinogaster the ridges are limited to the base of pectoral fin and gill membrane reaching isthmus. These Pampus spp. are easily distinguished based on internal features, such as number of vertebrae, gill raker, pyloric caeca, epipleural bone, esophageal sat and length of intestine.

A Study on the Publication of Liudao Pushuo, One of Mengshan De-yi's Works (몽산(蒙山) 덕이(德異)의 『몽산화상육도보설(蒙山和尙六道普說)』 판본고(板本考))

  • This thesis is a study of the printed books of Liudao Pushuo(六道普說), one of Mengshan(蒙山)'s works. Mengshan De-yi(德異) lived in the Song(宋) and Yuan(元) Dynasty and was a Buddhist monk of Linji Chan(臨濟宗). Liudao Pushuo exists only in Korea, and there is no copy in China. Liudao Pushuo is a summary of the preachings of Mengshan about the Ten dharma-worlds(十法界) which include the six realms(六道) and the four kinds of holy men(四聖). There are 22 printed books in Korea. This study analyzed their physical descriptions and structures. As a result, all the printed books have 'sajudanbyoun(四周單邊)' except one book that is 'julchopjang(折帖裝)' of 'Bulgapsa(佛甲寺)'. There are also ten books with 'Heukku(黑口) and naehyang heukumi(內向黑魚尾)'. This indicates that those were typical of the printing type of the early days of the Joseon(朝鮮) Dynasty. In addition, the books with 13 characters in one line(13字本) were common. All 22 printed books were published in the $15^{th}$ and 16th century. This study confirms that Liudao Pushuo was handed down in the Goryeo(高麗) from China and actively published in the 15th and 16th century. This shows that Mengshan's Seon(禪) had a significant effect on Buddhism in Korea.

  • This study was conducted to analyze community structure and species composition of Abies koreana forest. Field survey was carried out from June, 2019 to 2020, September. 121 plots (20×20 m) were set up, 5 herb layer plots (3×3 m) were constructed for each plot, and there, Diameter at Breast Height(DBH), height, environmental factor were measured. It was analyzed that water stress did not have a significant effect on the factors affecting the growth of A. koreana in Mt. Halla-san, and in the case of Mt. Deokyu-san, the more forest stands located at the ridge, the higher the tree density. It was found that the factors affecting the distribution of Abies koreana were not consistent according to the environment of study site.
