  • Purpose: This study was conducted in order to the relationship between life satisfaction, health behaviors, and successful aging and factors associated with successful aging. Methods: Participants in this study included 159 elders living in one city. Data on life satisfaction (Choi's Life Satisfaction Scale for Korean elderly, 1984), health behaviors (Choi & Kim's Health Behaviors Scale for Korean elderly, 1997), and successful aging (Kim & Shin's Successful Aging Scale for Korean elderly, 2005) were collected by trained interviewers. For analysis of collected data, the PASW 18.0 program was used, which included descriptive analysis, t-test, ANOVA, Scheffe test, Pearson correlation coefficients, and Multiple regression. Results: Results showed a positive correlation between life satisfaction, health behaviors, and successful aging. Life satisfaction, self-perceived health status, and health behavior explained 60.8% of successful aging. Conclusion: There is a need to help improve health behavior and self-perceived health status of elders. We should also understand life satisfaction over their life span and establish a program that encourages healthy behavior in the community.

  • Purpose: This study was done to investigate factors influencing successful aging in middle-aged women. Methods: A convenience sample of 103 middle-aged women was selected from the community. Data were collected using a structured questionnaire and analyzed using descriptive statistics, two-sample t-test, one-way ANOVA, Kruskal Wallis test, Pearson correlations, Spearman correlations and multiple regression analysis with the SPSS/WIN 22.0 program. Results: Results of regression analysis showed that significant factors influencing successful aging were post-traumatic growth and social support. This regression model explained 48% of the variance in successful aging. Conclusion: Findings show that the concept 'post-traumatic growth' is an important factor influencing successful aging in middle-aged women. In addition, social support from friends/co-workers had greater influence on successful aging than social support from family. Thus, we need to consider the positive impact of post-traumatic growth and increase the chances of social participation in a successful aging program for middle-aged women.

  • Purpose: This study explored the relationships of maturity fears and appearance interest(interest in appearance, interest in weight) with self-concept among girls with precocious puberty. Methods: The participants for this study were 120 elementary school students (8 to 10 years old) and their parents from two hospitals located in Chungcheong Province. Data were collected from January to February 2019 using self-reported questionnaires. The collected data were analyzed using descriptive statistics, the independent t-test, the Mann-Whitney U test, one-way analysis of variance, Pearson correlation coefficients, and multiple regression analysis in SPSS for Windows version 23.0. Results: Statistically significant negative correlations were found between self-concept and maturity fears (r=-.34, p<.001) and interest in weight (r=-.29, p=.001). Maturity fears were identified as a factor affecting the self-concept of girls with precocious puberty (β=-.34, p<.001). This variable explained 11.5% of the variance in the self-concept of girls who experienced precocious puberty. Conclusion: This study confirmed that maturity fears had a major influence on self-concept in girls with precocious puberty. The results of this study can be used as basic data for the development of a psychosocial nursing intervention program for girls who experience precocious puberty.

Methods: A pilot survey, pre-test and post-test were conducted. The data were collected from August to October, 2009. The participants were 44 patients randomly assigned to an experimental group (22 people) and a control group (22 people). The experimental group received individual instruction for aroma inhalation, which lasted for 3 minutes. They inhaled blended oils of Lavender, Majoram and Ylang Ylang (The mixed ratio was 4:3:3), three times a day, for two weeks. Data from 36 patients were used for the final analysis (20 from the experimental group, 16 from the control group). Data were analyzed using SPSS version 13.0. Results: Sleep disturbance decreased in the experimental group (t=-2.258, $p$=.030). Blood pressure, pulse, stress, and anxiety were not significantly different between the two groups ($p$ >.05). Additional analysis of the experimental group showed that physical stress and psychological stress were significantly lowered. Conclusion: Aroma inhalation is an effective paramedical intervention for patients with essential hypertension.
