다국어 초록 (Multilingual Abstract)

Taking a look at the rock-paintings, Suk Tal-Hae myth, Wooro legend, we can confirm that Shilla had taken a lot of interest in territorial expansion to the east coast since its early age, based on its marine-fishery culture. And then Siljik-Joo in Sam-chuk, Aseulla-Joo in Kang-reung, Sokyung in Asichon were established along with Yi-sa-boo`s conquest of Woosan-Kook during the reign of King JiJeung. Through such activities, Shilla succeeded in securing the command of the east sea(Dong-hae) and the east coast. Shilla`s expansion to the east coast, ranging to Wool-jin, Sam-chuk, Kang-reung, during the reign of King Ji-jeung was probably accomplished in the form of feint operation, not only through the land traffic route but also through the coastal route by marine forces which had been maintained since Suk Tal-Hae` age from rock-paintings. Afterwards, Shilla, which captured those areas, probably launched the conquest of Woolreung-do from Wool-jin. Sam-chuk. These activities made it possible for Shilla to seize t:he rulling power over the east coast, east sea(Dong-hae) and finally make such rapid progress as dispatching Koanjoo(governor), subjecting Keumkwan-Kaya in the reign of King Bupheung as well as capturing the Han-river, the Nakdong-river basin, establishing Biyeulhole-Joo, conquering Kaya, setting up a number of stone monuments, which are now called King-Jinheung-Soonsoo-Bi, in Bookhan mountain, Hwangchoryung in Heungnam province, Maoonryung in Yione under the reign of King Jin-heung. Considerable amount of attention should be paid to the fact that Shilla`s feint operation through the went coast and the east coast against KoKooryu was possible by its taking economic power in the east coast, following its expansion to the east coast and conquest of Woosan-kook. In Shilla`s such a success, Woosan-kook`s coorporation played crucial role. Therefore, Woosan-kook was not so much destroyed as enjoying great prosperities with a relative stability, which was attributed to Shilla`s securing the command of the sea.
