Purpose: This study aimed to assess the levels of and relationships among health literacy, knowledge about diabetes, and self-care activities in the Korean low-income elderly with diabetes and to identify factors influencing the self-care activities of this vulnerable population. Methods: This study surveyed a total of 151 low-income elderly patients with diabetes registered at 16 Visiting Health Care Services in B City, Korea. Health literacy was measured with the Newest Vital Sign. Diabetes knowledge was measured with the Diabetes Knowledge Test. The Summary of Diabetes Self-care Activities Questionnaire was used to assess diabetes self-care activities. A stepwise multiple regression analysis was conducted to identify significant factors influencing diabetes self-care activities in these patients. Results: In the regression model, diabetes knowledge (${\beta}=.322$, p<.001), exercise (${\beta}=.337$, p<.001), and experiences of diabetes education (${\beta}=.241$, p=.001) were significantly associated with increased diabetes self-care activities in low-income elderly patients with diabetes when gender, education, health literacy, and subjective health state were controlled. Conclusion: To improve diabetes self-care activities in the low-income elderly with diabetes, it is important to develop a customized program considering their knowledge, exercise, and diabetes education experience.

Purpose: The purpose of this study was to explore predictors of successful aging in older Korean women based on a recent mid-range nursing theory, the Successful Aging Theory (SAT). Methods: This study utilized a descriptive correlational design. The convenience sample was composed of 174 older women living in the community. Successful aging was measured using the Successful Aging Inventory (SAI). Transcendence was measured using the Self-transcendence Scale (STS). Adaptation was measured using the Coping behavior scale. Stepwise multiple regression was used to identify significant predictors of successful aging. Results: Transcendence, adaptation, and religion were shown to be predictive of successful aging. This regression model explained 56% of the variance in successful aging. The factor with the highest influence was transcendence which explained 52% of the variance. Conclusion: Gerotranscendence-promoting interventions can be an important consideration in caring for older Korean women. Adaptation and spirituality should be included in a holistic aging care.

상대적으로 유역의 관측 자료가 충분하지 못하거나 검증되지 않았을 경우 미계측 유역으로 정의되며 수문모형의 매개변수 검정을 할 수 없으므로 다른 방법을 고안해야 한다. 이를 위해 기존 연구에서는 지역적 특성을 고려한 지역회기분석을 통해 미계측 유역의 유량을 산정하였는데, 대부분 유역의 특성과 연 평균 유출량 자료의 관계를 이용한 회귀식으로 실시간 유량의 변화를 고려하기 어려웠다. 본 연구에서는 개념적 강우-유출모형으로 많이 사용되고 있는 개념적 수문모형인 GR4J의 매개변수에 대해 미계측 유역의 특성을 고려한 변수들을 이용하여 회귀식을 구하고 그 적용성을 평가하였다. 이를 통해 미계측 유역의 유량 시계열 자료를 생성할 수 있었다. 또한 IPCC에서 발간한 AR5의 RCP 4.5 시나리오를 적용하여 미래 유출량을 산정하였다. 우선 지역회귀분석을 적용하기 위해 수문모형을 이용한 계측 유역의 유출량을 구하였으며 22개의 전국 댐 상류 지점을 기준으로 SCE 알고리즘을 이용하여 GR4J의 최적 매개변수를 구하고 각 유역별로 물리적, 지형적, 기상학적 특성을 고려하여 11개의 변수를 선택하였다. 각 변수간 다중공선성(Multicollinearity)를 고려하기 위해 VIF(Variation Inflation Factor) test를 적용하여 최종 7개의 변수를 선정하고 단계별 회귀방법(Stepwise regression)을 이용하여 GR4J의 매개변수별 회귀식을 생성하였다.
