Individual donors that are the social and financial base of organization finance are divided into prospect, current donors and lapsed donors. This study might be the first efforts in Korea, to reveal the characteristics and behavior of lapsed donors. We found that major reasons of giving lapse were financial inabilities and interest of other cause. However, many lapsed donors didn't give any more but moved to another nonprofit organization for donation. Moreover, their trust of ex-nonprofit organization has effected their decision to donate to other nonprofit organizations again or not. Therefore, donor services that improve donors' trust is important to maintain nonprofit sector' donor basis.

Cotyledonary somatic embryos after being cultured in a liquid MS medium for 1 week were subcultured on a solid MS medium and then the embryos germinated at a rate of 92%, but the rate was lowered by extending the culture period of the embryos on a liquid medium: 26% germination on a liquid medium culture for 4 weeks. Somatic embryos subcultured on the liquid medium showed the normal elongation of hypocotyl and radicle but in part showed secondary embryogenesis on hypocotyl and callus formation on and around the root-hypocotyl juncture. Through observation of scanning electron microscope, apical meristem in plumule showed the loose arrangement of cells, and abnormal leaf primordium formation and growth arrest of the primordium or no leaf primordium formation. Therefore, it is suggested that the germination arrest of carrot somatic embryos on liquid medium culture is due to the structural abnormality of the apical meristem in plumule.
