The nonlinear stabilities of'resistive MID modes are investigated in a tokamakconfiguration by a three dimensional MID simulation based on a rectanuularcolumn model under the fixed boundary condition. The m=='1 internal resistivekink mode is excited for the central safcty factor, q0< 1, resulting in a sawtoothoscillation of temperature. Only the m=2 mode is excited for q.<2 and a smallresistivity. On the other hand, the several modes of ( -m: n)=(2: [), (I : I) and(3 : 2) appear for q,)< 2 and a little large resistivity depending on the<7-configurationthrough the variation of toroidal current. The (3 : 2) mode plays an importantrole on the mode coupling between the (1 : 1) and (2: 1) modes. As the result,='- the (2: 1) mode finally determines the stability and stable configurations ofplasma are formed with the condition of q>,2.
