The preconditioned Krylov subspace methods were applied to the incompressible Navier-Stoke's equations for convergence acceleration. Three of the Krylov subspace methods combined with the five of the preconditioners were tested to solve the lid-driven cavity flow problem. The MILU preconditioned CG method showed very fast and stable convergency. The combination of GMRES/MILU-CG solver for momentum and pressure correction equations was found less dependency on the number of the grid points among them. A guide line for stopping inner iterations for each equation is offered.

This study aims to explore the meaning of marital life from the point of women marriage immigrants through the phenomenological qualitative methodology by Giorgi. Results showed that the meaning of marriage life were 'love, the attraction of various colors','husband, really good person', 'the reality', 'child: stability, pleasure and hardship','husband demanding Korean women's life', 'difficult and good in-laws', 'marriage is my power', 'community beyond marriage life'. The meaning that participants experienced was living like Korean woman with really good husband in unfamiliar and afraid society. This meaning was beyond the objectified negative typification of women marriage immigrant.
