Our analysis results cover the relationships among the two factors, smart-phone addiction level, present-hedonic perspective, and future time perspective. In addition, we analyze the relationship among the factors with a structural equation model. By doing these, we propose educational alternatives in terms of time and plan to improve our adolescent's abstract thinking level, which helps their problem solving skills and their academic achievement.

Due to the advent of new smart devices, the new technology addiction problems have been much severer than the Internet addiction recently. A lot of research about each technology addiction has been proposed, but the research about the changes in the addictions has been rare. In this paper, we analyze how the environmental factors such as parents and friends affect the personal factors such as time perspectives and technology usage time. In addition, we get the relative importances among the factors which influence on the Internet and mobile phone addictions. As a result, we can analyze the relationships among the factors and the differences between the two addictions with time perspective. In order to achieve our goals, we surveyed on 1,420 primary and secondary school students. We also provided the results produced by structural equation model and Budescu's Dominance analysis. Based on these analyses, we described the differences between the Internet and mobile phone addictions and proposed an alternative to prevent new technology addictions.

Methods: This study applied a 6-week weight loss program with dietary education, exercise therapy, and behavior modification therapy from 4 June 2012 to 20 July 2012. The collected data were analyzed by descriptive statistics and the Wilcoxon signed rank test using the SPSS WIN 18.0 program. Results: After the 6-week program, the average weight of the subjects was reduced from 75.96kg to 74.41kg (Z=$-3.994^p$, p<.001), while the body mass index (BMI) decreased from 29.23 to 28.60 (Z=$-3.980^p$, p<.001), and the obesity index decreased from 38.45% to 35.59% (Z=$-3.977^p$, p<.001). The percentage of body fat decreased from 32.45 to 31.92 (Z=$-3.947^p$, p<.001), and the rate of skeletal muscle growth increased from 26.06% to 26.58% (Z=$-3.822^p$, p<.001). Conclusion: A weight loss program using a SNS (social network service) application, with dietary education, exercise therapy, and behavior modification therapy can reduce obesity and impact body composition in a short-term.

The main factors of smartphone addiction discrimination were divided into 'aim for imaginary', 'daily obstacles', 'tolerance', 'withdrawal symptom'. Smartphone addicted group members show the result of r=0.668 (physical aggression), r=0.704 (verbal aggression), r=0.481 (hostility). (p< 0.001). This study focused on the aggression from smartphone overuse and the positive effect of music for adolescent's mind stability.

Objectives: The purpose of this study was to evaluate the association between Internet use and oral health behaviors in Korean adolescents. Methods: This study used the 13th Korea Youth Risk Behavior Web-based Survey (2017) to find an association between Internet use and oral health behaviors. The total number of study subjects was 54,603. A chi-square test and multiple logistic regression analyses were used to estimate the association between Internet use and oral health behaviors. Results: Internet use was significantly increased among female, higher school grade, lower school records, and lower economic status participants (p<0.001). The rate of frequency of toothbrushing more than three times daily and use of oral hygiene devices was increased among female, higher school record, and higher economic status participants significantly (p<0.001). Oral symptoms experienced were significantly increased among female, higher school grade, lower school records, and lower economic status participants (p<0.001). The rate of the toothbrushing more than three times daily and toothbrushing after lunch groups was the highest in the group with less than one hour of Internet use, but the rate of oral symptoms experienced was the highest in the group with over five hours of Internet use. The risk of toothbrushing less than twice daily was 1.61 times higher in the group with over five hours of Internet use, and the risk of not brushing after lunch was significantly higher (1.52 times) in the over five hours group. The risk of not using oral hygiene devices was the highest (1.22 times) in the less than five hours group, and the risk of oral symptoms experiences was 1.40 times higher in the more than five hours group. Conclusions: Internet use was related to oral health behaviors in adolescents. Appropriate Internet use and awareness of oral health care are needed among adolescents.

This study analyzed the latent profile for identifying the difference in the dependence on smartphone use among middle school students in the 1st grade using the Korean Children and Youth Panel Survey (KCYPS). From the result of this study, first the latent class was separated according to the type of dependence on smartphone use. Class 1 included the students (from fifth grade in elementary school) whose level of reliance on smartphone use was low. Class 2 was selected as the group whose level of reliance on smartphone was high. Secondly, in comparing class 2 to class 1, it was found that the students who have a high probability of being in class 1 were those whose fathers are high achievers, have high early self-esteem and less age attachment. Thirdly, the students in class 1 had a higher sense of neglect than those in class 2. Furthermore, the self-determination of the students in class 2 mediated the effect of neglect on the adolescents' dependence on smartphone use both directly and indirectly.
