              The past three decades have witnessed a remarkable growth in nursing science development. In both Korea
              and the United States, nurse scientists are poised to address important issues related to the prevention and
              management of significant health care problems. The need for greater nursing science development in the
              areas of self management, genetics, geriatrics, health promotion across the lifespan, technology, and mental
              health are briefly highlighted. Future research efforts will be enhanced by interdisciplinary collaboration
              and the creation of international nursing research centers. At the same time, we need to remain cognizant
              of the importance of mentoring future nurse scientists. [Asian Nursing Research 2007;1(1):4–10]
