This study was performed to investigate the effects of academic stress and academic burnout on smartphone addiction in junior high school students. A survey was conducted using a convenient sample drawn from 306 students at six junior high schools in Seoul. Data were analyzed using the SPSS 23.0 program. The results show that 21.6% of students were at risk of smartphone addiction. The high risk of smartphone addiction group used smartphone longer during weekdays and weekends. In addition, the high level of academic stress and academic burnout groups showed higher smartphone addiction scores compared to the lower level of academic stress and academic burnout groups. Smartphone addiction was positively correlated with academic stress and academic burnout. Furthermore, the results show that academic achievement and attending class, academic stress and disengagement, and academic burnout affected smartphone addiction. Therefore, to prevent smartphone addiction in adolescents, academic stress should be reduced in adolescents as well as develop educational programs to help students release or control their academic stress.

본 연구는 스마트폰 기반 모바일거래를 통해 이용자가 추구하는 핵심 가치가 무엇인지 파악하고, 이러한 가치가 이용행위에 미치는 효과를 검증한다. 구체적으로, 본 연구는 이용자의 지각된 가치를 시간적 가치, 기능적 가치, 경제적 가치의 세 가지 차원으로 개념화하고 모바일거래 이용에 미치는 개별적인 효과를 검증한다. 이와 더불어, 본 연구는 스마트폰 기반 모바일거래의 핵심특성으로 서비스 편재성과 이용자 통제성을 제시하고, 어떻게 이들 특성들이 이용자의 핵심 가치 창출과 관련되어 있는지를 규명하고자 한다. 스마트폰 기반 모바일거래 이용자를 대상으로 수집한 164개의 데이터를 가지고 PLS 분석을 한 결과는 다음과 같다. 첫째, 스마트폰 기반 모바일거래 이용은 시간적, 기능적, 경제적 가치들에 의해 결정되며 특히, 시간적 가치의 영향력이 가장 큰 것으로 나타났다. 둘째, 서비스 편재성은 시간적 가치에 유의적이지만 기능적 가치에는 비유의적인 것으로 나타났다. 마지막으로, 이용자 통제성은 시간적 가치 및 기능적 가치에 모두 영향을 미치는 것으로 나타났다. 종합적으로, 본 연구결과는 모바일거래의 이용이 시간적 가치에 의해 상당히 영향을 받으며, 시간적 가치는 서비스 편재성과 이용자 통제성에 의해 증가함을 제시한다.

Purpose: This study was done to identify the status of smartphone addiction among nursing students and to examine the mediating effects of Internet ethics on the relationship between smartphone addiction, physical symptoms and psychological well-being. Methods: Data were collected between May 20 and June 23, 2014. Participants were a convenience sample of 214 nursing students of one university in Seoul. Structured questionnaires were used to measure degree of smartphone addiction, physical symptoms, psychological well-being and Internet ethics. Data was analyzed using Independent t-test, One-way ANOVA, Pearson correlation coefficient, multiple hierarchical regression. Results: Of the nursing students, 14.5% had high level of risk of smartphone addiction and 16.8% had potential risk. Higher frequency of physical symptoms and lower level of Internet ethics were related to the higher level of smartphone addiction. Voluntary-control in Internet ethics had mediating effects on the relationship between smartphone addiction and physical symptoms. Conclusion: The results suggest that the level of smartphone addiction may lowered in nursing students by intensifying Internet ethics especially voluntary-control. Based on these findings, Internet ethics program for nursing students should be developed to facilitate the effective use of smartphones.

본 연구의 목적은 스마트폰 사용자들의 의사결정에 영향을 미치는 요소들을 탐구하는 것이었다. 본 연구는 친밀감, 개인연결성, 사용 및 의존성, 친숙함 및 전문성, 효능 및 효과, 자아정체성, 제어 등을 독립 변수로 설정하고 의사 결정을 종속 변수로 설정한다. 본 연구에서는 스마트폰 사용자 200명을 설문지를 통해 수집 분석하였으며, 변수간 영향을 파악하기 위해 Smartpls 3.0을 사용하였다. 스마트폰 사용자의 심리적 강도에 영향을 준 6가지 요인 중 5가지가 의사결정에 영향을 미친 것으로 분석됐다. 또한 조절변수로서의 사용 기간 등이 심리적 영향과의 관련성도 살펴보았다. 본 연구 분석 결과는 이전에 스마트폰의 심리적 영향에 대한 요인들에 연구가 미진한 가운에 스마트폰 기기의 발전 형태의 소비자 행동 기반이 될 수 있고, 향후 본 연구를 바탕으로 스마트폰 시스템 개발에 도움이 될 것으로 기대한다.

This study investigated the effect of food consumption monitoring and real-time communication-based weight control program using a smartphone on weight reduction and maintenance in obese women. This study consisted of two phases: an 8-week weight control program with food consumption monitoring and real-time communication using a smartphone and an 8-week follow-up. Sixteen obese female college students (>30% body fat) participated in this program, and we measured changes in body composition and dietary intake volume. Follow-up analysis focused on weight maintenance after 8 weeks of no contact. Total energy intake (P<0.01), body weight (P<0.001), percent body fat (P<0.001), body fat (P<0.05), and body mass index (P <0.001) decreased significantly after the 8-week weight control program. However, we could not observe total energy intake or body composition regain after the follow-up period. These results suggest that food consumption monitoring and real-time communication using a smartphone can be effective for weight control and maintenance.

Purpose: This study was done to verify effects of a self-directed feedback practice using smartphone videos on nursing students' basic nursing skills, confidence in performance and learning satisfaction. Methods: In this study an experimental study with a post-test only control group design was used. Twenty-nine students were assigned to the experimental group and 29 to the control group. Experimental treatment was exchanging feedback on deficiencies through smartphone recorded videos of nursing practice process taken by peers during self-directed practice. Results: Basic nursing skills scores were higher for all items in the experimental group compared to the control group, and differences were statistically significant ["Measuring vital signs" (t=-2.10, p=.039); "Wearing protective equipment when entering and exiting the quarantine room and the management of waste materials" (t=-4.74, p<.001) "Gavage tube feeding" (t=-2.70, p=.009)]. Confidence in performance was higher in the experimental group compared to the control group, but the differences were not statistically significant. However, after the complete practice, there was a statistically significant difference in overall performance confidence (t=-3.07. p=.003). Learning satisfaction was higher in the experimental group compared to the control group, but the difference was not statistically significant (t=-1.67, p=.100). Conclusion: Results of this study indicate that self-directed feedback practice using smartphone videos can improve basic nursing skills. The significance is that it can help nursing students gain confidence in their nursing skills for the future through improvement of basic nursing skills and performance of quality care, thus providing patients with safer care.

This study investigated the relationship between smartphone addiction propensities and leisure satisfaction according to leisure time constraints among university students and attempted to promote an effective and desirable leisure culture. The main findings were as follows: First, leisure time constraints showed differences in terms of the withdrawal factors, overall smartphone addiction propensities, and leisure satisfaction; self-efficacy showed significant differences in terms of withdrawal and overall smartphone addiction propensities; and control showed a significant difference in leisure satisfaction. Second, in the case of university students, it was revealed that regardless of leisure constraints, as disturbance of daily living and tolerance are higher, leisure satisfaction is lower in those with smartphone addiction propensities.

Objectives : The current study investigated the risk of smartphone addiction among children and adolescents with or without attention-deficit hyperactivity disorder (ADHD), risk of depression, anxiety, and self-esteem using the Smartphone Addiction Scale Proneness, Kovac's Children's Depression Inventory, State-Trait Anxiety Inventory, and Rosenberg Self-Esteem Scale, commonly used in clinical medicine. Methods : Ninety five students with ADHD who visited psychiatry outpatient clinics completed the questionnaire. At the same time, 592 middle and high school students living in a similar area regardless of ADHD diagnosis, completed the questionnaire as control subjects. Results : Overall, 40.0% of 95 ADHD and 12.8% of 592 control subjects were classified as the smartphone addiction proneness group, 26.3% of the ADHD subjects and 8.3% of the control group were classified as the depression group, and 32.6% of the ADHD subjects and 16.2% of the control group were classified as the anxiety group. Significant differences were observed between the two groups. Conclusion : The results of this study suggest that ADHD subjects are more prone to smartphone addiction, becoming depressed or anxious than those in the control group. From this study, we could suggest that students with ADHD are more easily affected by smartphone addiction than normal control subjects. In addition, we might understand how some psychiatric problems like depression, anxiety, and low self-esteem are related to ADHD and smartphone addiction.
