18세기 영국은 시대적 변혁기였다. 영국은 대외적으로는 단속적으로 전쟁을 계속해야 했고, 내적으로는 산업 사회로 전환하고 있었다 영국의 선주들은 계속된 전쟁과 선박량의 팽창으로 인해 선원 부족 문제에 직면하였다. 영국 선주들은 이에 대해 척당 선원 수를 줄이고, 선원의 임금을 올려줌으로써 해결하고자 했다. 18세기가 경과하는 동안 영국 상선의 척당 선원 수는 지속적으로 감소하였다. 1710년 100톤급 선박 1 척당 22-23명이던 선원수는 1810년에는 5명으로 급감하였다. 이처럼 척당 선원 수가 감소한 것은 조타기, 양묘기, 권양기 등의 기계가 도입되고, 선박과 범장의 개량이 꾸준히 이루어졌기 때문이다. 게다가 18세기 내내 단속적으로 전쟁이 계속되었기 때문에 선주들로서는 적은 선원으로 선박을 운항할 수 있는 방법을 강구하지 않을 수 없었다. 또한 선주들은 임금을 올려줌으로써 선원들을 해상 생활로 유인하고자 했다. 18세기 중엽25실링에 불과했던 선원의 임금은 프랑스혁명전쟁기에 이르면 5-10파운드까지 치솟았다. 척당 선원 수가 감소하고 선원의 임금이 꾸준히 상승한 것은 전쟁이 지속된 18세기에 영국의 선주들이 급변하는 해운 환경에 적절히 대응한 결과였다고 할 수 있다.

The culmination of the culture in the Josun Dynasty was reached in the academic achievement of Sik Jo (pen name, Nammyung : 1501 - 1572). His work marked a moral boundary in academia at that time. When we consider his great fame, it was natural many scholars and his followers make him their scholastic and behavioral model. These followers formed the Nammyung School and they took active parts in politics in and out of government service until King Sunjo and Gwanghaegoon. But the execution of Inhong Jung (pen name, Rae-Am : 1536-1623), leader of the Nammyung School and mentor of Gwanghaegoon, served as a momentum for decentralizing the school at the time of The Enthronement of King Injo subsequent to dethronement of King Gwanghasgoon in 1623. Hongdo Ha (pen name, Gyumjae) then acted on behalf of the school when the school had lost its cohesion. The year 1728 witnessed the Moosin Year Disturbance led by Heeryang Jung, which was one of the loud cries raised by confucian scholars to regain the positions they had held before the Enthronement of King Injo. Moreover the Noron Party. the group of followers of Siyul Soug and also the party in power, forced the Namin Party, another party in this area, to support it, while it prohibited the Namins from taking any state examinations by law after the Moosin Year Disturbance had been subdued. The Noron Party designed to attract the Namin Party to their side by disturbing its cooperation with the Soron Party, the followers of Jung Yoon, a disciple of Siyul Song's. With the Noron Party's intricately planned policies and efforts, most pepole in the Namin Party in this area became part of the Toegye School in the end. This paved the way for combining the right side and the left side of the Nakdong River as a natural result. There were few eminent scholars or government officials in high positions from the right side of the Nakdong River. In the meantime many scholars had come to stand by either the Noron Party or the Toegye Schoo. But the majority of Confucian scholars' respect for Nammyung had not faded away and his books were still being published. King Jungjo finally granted Nammyung a Royal Oration for the Sacrificial Rite in 1796 and conferred government positions on his descendants after over a century of persecution. The royal edict triggered the revival of the scholastic trend in this area and built a promising foundation for thriving academic achievement in the 19th ecntury.
