다국어 초록 (Multilingual Abstract)

In the early days of Joseon dynasty, the central government took prohibition of residing in island area policy to its island area. This was because of the endless infesting Japanese raiders. Joseon government was unable to prepare defense plan for the Japanese raiders, rather, they deported the island residents to mainland. Instead, they used desert island to accumulate resources for the country. However, residents from Daemado moved to mainland in order to get daily necessity. Their livelihood was based on violating Joseon marine boundary. In order to stay in Joseon marine boundary, time to time they surrendered and infested as raiders. In spite the situation, Joseon dynasty handed out rice and clothes to supervise them, or sometimes sent military to banish them, but these were not the ultimate solution for the Japanese raiders in Deamado. In 1419, Joseon dynasty carried out a Daemado conquest in order to control the Japanese raiders. Later, residents of Daemado pleaded to expand the Jseon fishery and the lord of Daemado paid his tribute to Joseon government. Finally, Joseon government allowed residents of Daemado to get access to Gochodo fishery and at the same time, imposed fishery tax for their fishing activity. This is so called Jo-eo-Geum-Yak(Fishing regulation treaty). As a result, the Japanese raiders who often infested and pirated near Joseon marine boundary started to fish in the fixed area, and paid their fishery taxes for them passing the boundary. Consequentially, Jo-eo-Geum-Yak(Fishing regulation treaty) was an open treaty allowing Japanese to pass over Joseon marine boundary in outward point of view, but essentially, it was the transition of realization of marine boundary, and also is highly appraised as a diplomatic accomplishment effected regulatory measures to illegal fishing activity.
