The purpose of this study is to investigate the mediating effects of depression, academic helplessness, and smartphone addiction tendency in the relationship between self-esteem and grit of adolescents. Data from the 2018 (first-year) Korean Children and Youth Panel Survey were used in this study. The subjects of this study were 1,375 male and 1,166 female students in seventh grade school. The multiple mediation model analysis was conducted using the SPSS and PROCESS macro program. The results of this study are as follows. First, there was a positive correlation between self-esteem and grit, while self-esteem and grit had negative correlations with depression, academic helplessness, smartphone addiction. Second, it was found that the relationship between self-esteem and grit was mediated by depression, academic helplessness, and smartphone addiction tendency, respectively, and furthermore, it was found that all pathways mediated sequentially were also significant. These results suggest that education and intervention considering self-esteem, depression, academic helplessness, and smartphone addiction to be useful as a way to help adolescents develop interest in specific goals and continue their efforts in these days when smartphone use is common.

최근에는 혁신적인 디지털 기술을 이용한 다양한 응용 프로그램이 의료계에 소개되고 있다. 중독 과학 분야 또한 기술 혁신을 통해 중독 예방 관리 및 치료를 할 수 있는 방법을 적극적으로 모색하고 있다. 중독 회복에 있어 일상적인 환경에서의 적절한 치료개입과 장기적 관리에 대한 중요성은 널리 알려졌으나 낙인, 노출, 비용에 대한 우려로 정신의료서비스의 이용률이 저조했다. 따라서 중독 치료를 통해 전인적 성장을 돕는 자가 관리 체계가 있다면 유용할 것이다. 본 연구는 Davies(2015)의 라이프스타일 균형 모델(LBM)을 바탕으로 영국에서 개발된 웹기반 SUD 회복 프로그램인 Breaking Free Online(BFO)을 소개하고 향후 국내에서 적용 가능한 SUD의 치료적 개입 방향성을 제공하고자 한다.

This study verified theoretical model to explain adolescents' addictive use of smartphone. I used the data of 679 middle and high school students among 2013 internet addiction survey of National Information Society Agency(NIA). This study utilized structural equation modeling analysis to compare a suggestive model and alternative model. According to the final model, higher the satisfaction of family relationship, the addictive use of smartphone and emotional problems of adolescents were reduced. And, higher the addictive use of smartphone, higher the emotional problems of adolescents. Also, family relationship affects emotional problems via addictive use of smartphone. While, in the alternative model, path from amount of smartphone use to addictive use of smartphone was not significant. Results of this study suggest that family relationship variable may play an antecedent factor of addictive use of smartphone and emotional problems of adolescents and control of smartphone use is important to keeping a mental health of adolescents.

The purpose of this study is to present the mental model of young adolescents' media environment and the use and to provide several educational suggestions drawing on the revealed model. For this, the data were collected through 4 activities such as interview, picture drawings, word association experiment, and sentence completion task with ten 4-5th graders in elementary schools; they were qualitatively analyzed by 2 researchers. First, the meaning components driven by sentence completion task, word association experiment were totally 6 components: media device, connection(alienation), competence(provision), entertainment, adverse effects, ambilaterality. Second, the components of media mental model driven by pictures were 4 components: functions/competence, entertainment, conflict with paper books/sharing, harmfulness/ambilaterality. Third, the components from interview consisted of conflict between paper books and electronic media, communication-centeredness, fear(addiction) and users' qualification. Based on those results, careful examination in cyber talk, necessity of addiction prevention, active development of learning media and their balanced utilization with books, and healthful media literacy education and reinforcement of critical thinking were suggested.

This study verified the relationship between internet use, family relationship, and cyber violence victimization by comparing models. 2013 The survey of Internet addiction of National Information Society Agency was used in this study to verify relationship between variables. We compared the model which internet use impact cyber violence victimization through mediating fully family relationship and other model which internet use influence cyber violence victimization through mediating partially family relationship. Based on final model (model 1), More internet use was related to lower family bond and lower family bond was associated with more cyber violence victimization. This results imply that family relationship have an important role in relationship between internet use and cyber violence victimization rather than internet use impact directly cyber violence victimization.

Objectives: Investigating the survival of patients with cancer is vitally necessary for controlling the disease and for assessing treatment methods. This study aimed to compare various statistical models of survival and to determine the survival rate and its related factors among patients suffering from lung cancer. Methods: In this retrospective cohort, the cumulative survival rate, median survival time, and factors associated with the survival of lung cancer patients were estimated using Cox, Weibull, exponential, and Gompertz regression models. Kaplan-Meier tables and the log-rank test were also used to analyze the survival of patients in different subgroups. Results: Of 102 patients with lung cancer, 74.5% were male. During the follow-up period, 80.4% died. The incidence rate of death among patients was estimated as 3.9 (95% confidence [CI], 3.1 to 4.8) per 100 person-months. The 5-year survival rate for all patients, males, females, patients with non-small cell lung carcinoma (NSCLC), and patients with small cell lung carcinoma (SCLC) was 17%, 13%, 29%, 21%, and 0%, respectively. The median survival time for all patients, males, females, those with NSCLC, and those with SCLC was 12.7 months, 12.0 months, 16.0 months, 16.0 months, and 6.0 months, respectively. Multivariate analyses indicated that the hazard ratios (95% CIs) for male sex, age, and SCLC were 0.56 (0.33 to 0.93), 1.03 (1.01 to 1.05), and 2.91 (1.71 to 4.95), respectively. Conclusions: Our results showed that the exponential model was the most precise. This model identified age, sex, and type of cancer as factors that predicted survival in patients with lung cancer.

This study deals with exploring qualitative steps and paths that appear as YouTube users' usage time increases quantitatively. For the study, I applied theories from psychology and neuroscience, subdivided the interval between the personalization algorithm of the recommendation system, and active use and analyzed the relationship between variables in this process. According to the theory behavioral model theory (FBM), variable reward, and dopamine addiction were applied. Personalization algorithms easy clicks as triggers according to associated content presentation functions in behavioral model theory (FBM). Variable rewards increase motivational effectiveness with unpredictability of the content you search, and dopamine nation is summarized as stimulating the dopaminergic nerve to continuously and actively consume content. This study is expected to make an academic and practical contribution in that it divides the purpose of use of content in the personalization algorithm and active use section into four stages from a psychological perspective: first use, reuse, continuous use, and active use, and analyzes the path.

The purpose of this study was to examine the mediating effects of maternal family experience on the relationship between mothers' tendency to addicted to smartphones and the social competence of young children. The subjects of this study were 481 mothers who delivered infants to a kindergarten or daycare center in Jeju area After conducting the questionnaire, the results of the responses were analyzed. To analyze the collected data, structural equations were implemented using SPSS Statistic 18.0 program. The results of this study are summarized as follows. First, the correlational analysis showed that the tendency of the addiction of smartphone and the social ability of the infant showed a significant correlation with the mother's family experience. Second, in the relationship between the mother's smartphone tendency and the social competence of the infant, The research model and the competition model were set up to examine the mediating effect and the competition model was found to be more appropriate. As a result, it can be seen that mother's original family experience is partly mediated in relation to mother's tendency to add to smartphone and social competence of infant. Based on these results, the implications of this study and suggestions for subsequent research were discussed.
