"Singijonmangron(神氣存亡論; theory of mind-spirit activities)" is a medical discourse of Janggyeongak(張景岳) in the Ming[明] dynasty, and "Wongijonmangron(元氣存亡論; theory of original gi functioning)" is a work by Seoryeongtae(徐靈胎) in the Qing[淸] dynasty. One emphasized the importance of mind-spirit activities and the other said seriously about original gi functioning. We did a study on these two medical theories, and began with identifying the meaning of 'Gi' among the ancient chinese philosophy and medicine such as "Hwangjenaegyeong(黃帝內經)". After that, we showed the general 'Gi' and its variations in the meaning of 'Gi' according to name and function in "Hwangjenaegyeong(黃帝內經)"and other classics of prominent historic scholars of medicine, finally trying to find out the essentials of mind-spirit[神氣] by Janggyeongak(張景岳) and original gi[元氣] by Seoryeongtae(徐靈胎).
