The purpose of this study was to investigate the relationships among smartphone addiction, communication ability, loneliness, and interpersonal relationships in university students in Korea. Between 15 and 31 May 2016, 263 subjects completed a questionnaire consisting of questions on smartphone addiction, communication ability, loneliness, and health of interpersonal relationships. Among smartphone addiction questions there were significant differences between genders (t = 2.350, p = 0.019) and educational grade (F = 3.313, p = 0.021). With regard to human relationship health, the scores for males were significantly higher than those for females (t = 2.337, p = 0.020). The smartphone addiction and human relationship health results were negatively correlated (r = ?0.157, p = 0.011). In contrast, communication ability and human relationship health results were positively correlated (r = 0.581, p < 0.001). However, loneliness and human relationship health were not significantly correlated. The final multiple regression model explaining human relationship health included smartphone addiction (t = 2.753, p = 0.006), communication ability (t = 11.714, p < 0.001), and motivation for smartphone purchase (t = 2.125, p = 0.035) as independent factors. The final model explained 36.6% of the total variance. In order to improve university students' human relationship health, solutions for smartphone addiction and low communication skills are required. This results of this study can be used as a basis on which to develop a human relationship health intervention program.
This study is a descriptive survey study to identify the behavior of the Korean college student's eating alone and to verify the relations among the frequency of eating alone, the subjective health status and the depression. The research subjects were 194 persons. For the analysis method, t-test, ANOVA, Scheffe test, Pearson's correlation coefficient were used. In the results of study, While the frequency of eating alone showed the significant negative correlation with the subjective health status (r=-.299, p<.001) and the significant positive correlation with the depression (r=.661, p<.001), the subjective health status showed the significant negative correlation with the depression (r=-.154, p=.033). It was observed that the eating alone has correlation with the subjective health status and the depression. The results of this study suggested that the basic data for the development of efficient nursing intervention toward the dietary habit and attitude should be prepared to change the cognition on the eating alone, which may cause the long-term health problem and to maintain the physical and mental health of Korean college students.
