Purpose : The purposes of this study were to determine the relationships of communication skills with smartphone addiction and self-efficacy before clinical practice training among nursing students and to provide basic data for developing and verifying the effectiveness of an intervention program for improving nursing students' communication skills. Methods : This study targeted those who obtained consent to collect data explained the purpose and procedure of the study for the first and second graders of the nursing department at one university located in B city. The data collection period was from April 24 to May 13, 2023. A total of 207 questionnaire responses were included in the analysis. The collected data were analyzed using t-tests and analysis of variance in the SPSS/Win 230 program. The results were reported as real numbers, percentages, mean values, and standard deviations. The correlations between the variables were analyzed using the Pearson correlation coefficient. Results : Smartphone addiction according to the general characteristics of the study subjects showed significant differences in 'residence type' (F=2.91, p=.035) and 'average smartphone usage time' (F=20.15, p=.000). It seemed. self-efficacy was determined by 'age' (F=2.74, p=.045), 'subjective academic level' (F=7.71, p=.001), and 'average smartphone usage time' (F=3.96, p=.009) showed a significant difference. Communication skills showed a significant difference in 'average smartphone usage time' (F=3.83, p=.011). The correlation between the variables of the study subjects showed that self-efficacy was negatively correlated with smartphone addiction (r=-.42, p<.001), and communication ability was positively correlated with self-efficacy. It was found that (r=.55, p<.001). 15) Conclusion : On the basis of the study results, the higher the nursing students' smartphone addiction, the lower their self-efficacy, and the higher their communication ability, the higher their self-efficacy. Therefore, intervention research is necessary to develop interventions for preventing smartphone addiction and increasing communication ability among nursing students.

Purpose: This study was undertaken to identify the effects of a camp-type group counseling program based on the self-determination theory, for controlling smartphone usage amongst university students. The program consisted of smartphone overdependence, basic psychological needs, and adaptation to college life. Method: This was a quasi-experimental research with a non-equivalent control group design (pre-test and post-test design). A total of 38 freshmen (17 experimental and 21 control) participated in the study. Experimental subjects attended a two nights and three days camp, where the group counseling program included meetings for basic psychological needs (eg., autonomy, competence, and relatedness). Results: This study showed significant differences in basic psychological needs (Z=-2.91, p=.003) and adaptation to college life (Z=-3.47, p<.001). Although no significant difference was obtained in the degree of smartphone overdependence (p=.194), mean score of the experimental group pre-test and post-test changed from the level of potential risk users to general users. Conclusion: The current findings indicate that by considering the basic psychological needs and adaptation to college life, our program could be an effective intervention for controlling smartphone usage amongst college students. Therefore, we propose that a camp-type counseling program could be considered for application as group therapy for programs associated with preventing smartphone overdependence.

According to the widespread use of smartphone, various and abundant mobile applications have been used and lots of new companies have developed mobile applications. To revitalize mobile application market, a lot of research and experiments have been performed in application development and delivery industries. The purpose of this research is to figure out the usage pattern of smartphone application and purchasing criteria of mobile application. We categorized smartphone application users with respect to application selection criteria and examined the characteristics of the categorized users. As a result, the factors of purchasing criteria of the users with respect to smartphone application selection criteria and application type were categorized into 3 groups: aggressive usage group, middle usage group, and passive usage group. The result of this study indicates that the relationship between purchasing criteria and usage pattern in mobile application market was actualized by measuring the purchasing factors of user. Therefore this fact suggests that it is very important to measure the accurate purchasing factors of its user for setting up the marketing strategy of mobile application market.

Secondary data was analyzed to be collected from a nationally representative sample of 2017 Korean adolescents. This study sample included 54,601 students in middle or high schools of Korea. The collected data were analyzed SPSS version 23.0 program for frequency, percentage, mean, standard deviation, t-test, ANOVA, Pearson's correlation coefficient and binary logistic regression analysis. In the results, the mean usage hour of smartphone among the adolescents was 28.42 (SD 23.30) per week. Analyses of the differences in usage hours of smartphone according to research variables were found that the groups of lower level of study (F=1361.067, p<.001) and sociality content type (F=761.549, p<.001) spent more time, as compared to the other groups. The logistic analysis showed the predictive factors for increased hour of using smartphone were smartphone usage for sociality (OR: 2.44, 95% CI: 2.26-2.64) and peer group counselor (OR: 1.49, 95% CI: 1.49). Conclusionally, the findings of this study suggests that it needs to understand cause or purpose of smartphone using of adolescent and to cope and educate on the cause.

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.

This study examines the roles of user resistance and social influences on the acceptance and continuous usage of smartphones at different stages of adoption. The respondents were classified into three groups according to their innovation adoption stage : non-user group, the potential user group and the trial user group. Theories relevant to user resistance, social influences including normative social influences and informational social influences, as well as user adoption and continuance behavior were reviewed and integrated into our research model. In order to verify the proposed structured equation model, we conducted an online survey by targeting mobile phone users and collected data to be analyzed through a partial least squares (PLS) test. This study tested whether there exists differences in the effects of user resistance and different types of social influence on user's adoption or continuance intetion among these three groups. The results showed that user resistance exists in all adopter groups and that it has significant negative influences on intention to use a smartphone. The findings also revealed that user resistance can be enhanced or resolved by two types of social influence; informational social influence resolves user resistance regardless of the adopter category, while normative social influence enhances the user resistance of potential users. Furthermore, the findings show that social influence regardless of the type positively affects user intention. Several theoretic and practical implications pertaining to the results are discussed.
