The studies on Nam-Gang through have attempted to look at the root of his social ideology which was the foundation of his business ethic and its possible impact on the current Christianity-based Corporate Social Responsibility(CSR). He was born at the juncture of declining old Chosun dynasty and the forced opening of the country by Japanese invasion. In his birthplace in North-West province of the country, there were some prominent commercial, industrial capitalistic activities prevailing. Christian faith and culture were relatively early landed at the province and were working for an era dawning as this area had been neglected by the central power of Chosun confucian dynasty. He accumulated a great amount of capital by conducting international commerce, and transporting related business. His business featured a more modernistic management, and CSR, compared to most of other hand-craft level of industries in Korea at that epoch. A well-known Korean independence movement enlightener, followed by his conversion through a sermon by Rev Han Suk Jin in Pyoung yang. Compared to many other christian pioneers who lost faith when their efforts to set the country from Japanese colonization were frustrated, his faith was rather taking root firmly as a basis for his endeavor to independence as well as prosperity movement for his people. His encounter with Dosan led him to operate his business with patriotic spirit. In other words, he returned most of capital profit earned from his business for the CSR. His business purpose can be summarized as to save the nation through economy, education and social reform. He led an organization called SinMinwhoi and encouraged people to establish national capital and improve the productivity against the Japanese capitalistic invasion. His national spirit is clearly reflected in national events such as 105 people 1st of March movements. National independence movement, business activity and his Christian faith were inseparable. To him, a faith unrelated to the deliverance of the nation was meaningless. His business spirit as a Corporate Social Responsibility Also his business spirit as a steward of God demonstrated the quality of honesty, hard working for the liberation of the nation. The humanistic effort for the improvement of the working condition, and the deliverance of the nation through education and among social activity were the two pillars of his ideology which can be a challenging lesson to the present-day people in business field as well as education and social activists. The key point of his business ideology is that the purpose of business as a steward of God is not in pursuing capitalistic interest itself but in returning it to the society. Moreover, he donated his body in his death to make a sample for the biology students.
