PURPOSE
The purpose of this study was to investigate the relationship of depression and smartphone dependency with female college students' career decision-making self efficacy.
METHODS
This was a descriptive study. The survey participants were 497 female college students in M City and S City. Data were collected from November 16 to December 4, 2015 using self-report questionnaires including BDI (Beck Depression Inventory), Smartphone Dependency Scale, and CDMSES-SF (Career Decision-Making Self Efficacy Scale-Short Form). Data were analyzed through descriptive statistics, independent-samples t-test, ANOVA, and stepwise multiple regression.
RESULTS
Career decision-making self efficacy showed significant differences according to religion. Smartphone dependency was found to have a statistically significant negative correlation with career decision-making self efficacy and a positive correlation with depression. Depression was found to have a statistically significant negative correlation with career decision-making self efficacy. Stepwise multiple regression analysis revealed that the predictors of career decision-making self efficacy were depression (7.1%), religion (1.8%), and smartphone dependency (1.3%), accounting for a total of 10.6% of the variance.
CONCLUSION
This study suggests that interventions to promote female college students' career decision-making self efficacy should consider their depression, religion, and smartphone dependency.

PURPOSE
The purpose of this study was to investigate the relationship among family functioning, empathy and aggression by high school students.
METHODS
This was a descriptive study. The survey participants were 467 high school students from M city. Data were collected from November 29 to December 7, 2012 and self-report questionnaires including a Family Adaptability Cohesion Evaluation Scale, Interpersonal Reactivity Indexes, and an Aggression Questionnaire. The collected data were analyzed by descriptive statistics, independent-samples t-test, ANOVA, stepwise multiple regression.
RESULTS
The majority of the subjects were 2nd graders (42.0%) and female (57.2%). 59.7% of the subjects had religion, 84.8% were living together with parents. The mean ages of their fathers and mothers were 49.90+/-0.20 and 46.85+/-0.19 respectively. Aggression was found to have a statistically negative correlation with family functioning and empathy. Stepwise multiple regression analysis revealed that the most powerful predictor of aggression was empathic concern. Empathic concern, family cohesiveness, perspective taking, personal distress and gender accounted for 16.7% of the variances.
CONCLUSION
It is necessary to provide aggressiveness reduction programs for high school students that consider their family functioning and empathy.

AbstractAbstract PDF
PURPOSE
This study was conducted in order to investigate the effects of an aerobic exercise program on mobility, fall efficacy, balance, and stress in the elderly at senior centers.
METHODS
This research was conducted as a quasi-experimental pretest and posttest control and experimental comparison study. The subjects were 41 senior residents (Exp.=18, Cont.=23) who aged above 65 at senior centers in S City. The period of time for data collection and intervention was from August 25 to December 5, 2008.
RESULTS
Mobility (t=-3.10, p<.01) in the experimental group were significantly higher than those in the control group without an aerobic exercise program. However, fall efficacy (t=1.28, p=.207), balance (t=-.53, p=.602; t=.36, p=.723), stress (t=-1.32, p=.199) in the experimental group was not significantly higher than that in the control group.
CONCLUSION
These findings confirmed that aerobic exercise programs make a contribution to improving mobility in the elderly at senior centers.

AbstractAbstract PDF
PURPOSE
The purpose of this study was to investigate the effects of perceived stress on cognition in the community elderly.
METHODS
This was a descriptive study. Data were collected using individual-based interviews from 40 senior residents at the hall for the elderly in S City. The period of data collection was from June 19 to July 7, 2006. The tools of data collection were Mini-Mental State Examination (Folstein, Folstein, & McHugh, 1975) and Perceived Stress Scale (Cohen, Kamarck, & Mermelstein, 1983).
RESULTS
Cognition showed significant differences according to gender, education, and regular exercise. Cognition was significantly correlated to stress and age. Stress was significantly correlated to orientation, recall, and attention/calculation. In the results of stepwise multiple regression, factors affecting cognition were stress, age, and gender.
CONCLUSION
It is necessary to prepare health promotion programs that can reduce stress level in the community elderly.
