Lately, Internet-based vessels have begun to appear at sea with the development of ICT. Thereby crews have gained easy Internet access through increased smartphone portability. However, the side effects of smartphone use while on watch, have not been studied seriously despite being a reality. In this study, simulation experiments were carried out using a Ship Handling Simulator in order to distinguish the risks of using a smartphone while on watch. Proximity Evaluation, Control Evaluation, Subjective Evaluation and Situation Awareness to the dangerous situation were used to quantify risk during simulation, and analysis results were compared with cases when using and not using a smartphone. It was found that the degree of risk increased between 1.3 to 3 times given smartphone use. Consequently, this paper represents foundation for the restriction of smartphone use and proposes smartphone usage guideline for ship navigation.

This study attempted to verify the structural model of the effects of stress, self-efficacy, and self-control on smartphone addiction in University students. The subjects of this study were 440 University students in G and P city. Results, First the most influential variables on smartphone addiction were self-control, followed by stress, and two variables explained explanation about smartphone addiction in 34%. Second, self-efficacy had a positive effect on self-control and stress had a negative effect. Both variables had an indirect effect on smartphone addiction through self-control. In groups less than 4 hours and above, there was a partial regulation effect because of differences between groups in the smartphone addiction pathway coefficients of stress and self-efficacy. Therefore, in order to reduce smartphone addiction, it is important to find ways to reduce stress and increase self-control and self-efficacy, and necessary to develop various programs and tailor educational interventions for each individual situation.

This study investigated the effects of empathy, self-control, and smartphone dependency on the interpersonal relationships of nursing students. The survey participants were 157 students in A city. The data was collected through self-report questionnaires that were obtained from May 27 2019 to May 31 2019. The data was analyzed using descriptive statistics and Independent t-tests, One-way ANOVA, Pearson correlation coefficients, and Stepwise multiple regression analysis of the SPSS 14.0 program. As a result, self-control (F=5.319, p=.006) and smartphone dependency (F=4.854, p=.009) showed significant differences according to the school records. Smartphone dependency (t=-3.381, p<.001) showed significant differences according to smartphone use. Age was found to have a statistically positive correlation with self-control (r=.194, p=.015) and it had a negative correlation with smartphone dependency (r=-.223, p=.005). Self-control was found to have a statistically positive correlation with empathy (r=.244, p<.01), interpersonal relationship (r=.540, p<.001). and negative correlation with smartphone dependency (r=-.432, p<.001). Empathy was found to have a statistically positive correlation with interpersonal relationships (r=.476, p<.001). Stepwise multiple regression analysis revealed that the predictors of interpersonal relationships were self-control (β=.477, p<.001), empathy (β=.359, p<.001), and smartphone use (β=.208, p<.01) which accounted for 45.0% of all the variance (F=12.029 p<.01). An enhancement program of nursing students' interpersonal relationships is needed that considers their self-control, empathy, and smartphone use.

Smartphone use has become a part of everyday life, not only for adolescents but also for elderly and older people. Thus, this study explored the effect of demographic variables, the amount of smartphone usage, type of smartphone use and psychosocial variables on smartphone dependence of the elder group. We analyzed the data of 5627 (50s and 60s) of the Internet overdependence survey data of the Korea Information Society Agency in 2016. As a result of hierarchical multiple regression analysis, More frequency of smartphone use of weekday and weekend, and usage time of smartphone of weekday were related to greater smartphone dependence. More smartphone use for information seeking and games were associated with greater smartphone dependence. And, as loneliness and anxiety increased, smartphone dependence increased, while smartphone dependence decreased, as social capital increased. Through this study, it is necessary to understand characteristics related to smartphone dependence of elder and older group, and to use this knowledge to solve their smartphone dependence. Future studies also need to identify the causal relationship between predictors of smartphone dependence in elderly and older people.
