This study looked upon unity, closure, structure, and subject, in five text of <Ganghoguga> written by Na, Wi-so(1582∼1666). The result of this study is as follow; 1. We understood unity made by repetitive expression, closure made by repetitive expression in last part, logical structure of introduction and body, in the first text(the 1∼3 Sijo) of <Ganghoguga>.
2. We understood unity and closure made by symmetrical expression, and symmetrical structure of background time, background space and logic, in the second text(the 4∼6 Sijo) of <Ganghoguga>.
3. We understood unity made by repetitive expression, closure made by repetitive expression in last part, and logical structure of body and conclusion, in the third text(the 7∼9 Sijo) of <Ganghoguga>.
4. We understood unity made by symmetrical expression, closure made by symmetrical expression and repetitive expression in last part, and symmetrical structure of background time, background space, logical structure of introduction, development, turn, and conclusion, in the fourth text(the 1∼3, 7∼9 Sijo) of <Ganghoguga>.
5. We understood unity made by repetitive expression and symmetrical expression, closure made by symmetrical expression and repetitive expression in last part, symmetrical structure of background time, background space, and logical structure of introduction, body, and conclusion, in the fifth text(the 1∼9 Sijo) of <Ganghoguga>.
According to the result above, We understood a probability of desorption type in <Ganghoguga>, because unity, closure, structure, and subject are found in five text each.
