Internet addiction (IA) has become a widespread and problematic phenomenon as smart devices pervade society. Moreover, internet gaming disorder leads to increases in social expenditures for both individuals and nations alike. Although the prevention and treatment of IA are getting more important, the diagnosis of IA remains problematic. Understanding the neurobiological mechanism of behavioral addictions is essential for the development of specific and effective treatments. Although there are many databases related to other addictions, a database for IA has not been developed yet. In addition, bioinformatics databases, especially genetic databases, require a high level of security and should be designed based on medical information standards. In this respect, our study proposes the OAuth standard protocol for database access authorization. The proposed IA Bioinformatics (IABio) database system is based on internet user authentication, which is a guideline for medical information standards, and uses OAuth 2.0 for access control technology. This study designed and developed the system requirements and configuration. The OAuth 2.0 protocol is expected to establish the security of personal medical information and be applied to genomic research on IA.

This study was conducted to propose anti-stigma strategies by verifying the social stigma on behavioral addiction under the premise that social stigma is a main obstacle to the treatment of addiction. A research model was constructed by applying the attribution affection theory and the modified attribution affection theory, which are very useful for explaining emotional and behavioral responses to the persons with mental illness. In other words, when attributing the causes of behavioral addiction to the personally controllable things such as personality, will and lifestyle, social distance can be increased by the mediate of anger. However, when attributing the causes of behavioral addiction to biological factors that can not be controlled by an individual, there can exist two pathway, one is the arising of helping behaviors by the mediate of sympathy (the attribution affection theory), and the other is the aggravation in the social distance due to rising fear (the modified attribution affection theory). In order to verify the research model, 383 adult subjects mainly in South Gyeongsang Province were randomly presented with the vignettes of gambling addiction and internet game addiction, and asked about the causes of the problems and their emotional, prejudicial, and behavioral responses to them. As a result, all pathway had statistically significant predictive effect. Therefore, in the case of attributing to personal causes, social distance increased by the mediate of anger. In the case of attributing to biological causes, both pathway had significant predictive effect, but the indirect effect of the pathway predictive of the helping behavior by the mediate of sympathy was greater. Researchers suggested that anti-stigma strategies, which emphasize that behavioral addiction is a mental health problem requiring treatment, are necessary.

Objective: In this study, we used resting-state fMRI data to map differences in functional connectivity between a comprehensive set of 8 distinct cortical and subcortical brain regions in healthy controls and Internet addicts. We also investigated the relationship between resting state connectivity strength and the level of psychopathology (ex. score of internet addiction scale and score of Barratt impulsiveness scale). Background: There is a lot of evidence of relationship between Internet addiction and impaired inhibitory control. Clinical evidence suggests that Internet addicts have a high level of impulsivity as measured by behavioral task of response inhibition and a self report questionnaire. Method: 15 Internet addicts and 15 demographically similar non-addicts participated in the current resting-state fMRI experiment. For the connectivity analysis, regions of interests (ROIs) were defined based on the previous studies of addictions. Functional connectivity assessment for each subject was obtained by correlating time-series across the ROIs, resulting in $8{\times}8$ matrixs for each subject. Within-group, functional connectivity patterns were observed by entering the z maps of the ROIs of each subject into second-level one sample t test. Two sample t test was also performed to examine between group differences. Results: Between group, the analysis revealed that the connectivity in between the orbito frontal cortex and inferior parietal cortex, between orbito frontal cortex and putamen, between the orbito frontal cortex and anterior cingulate cortex, between the insula and anterior cingulate cortex, and between amydgala and insula was significantly stronger in control group than in the Internet addicts, while the connectivity in between the orbito frontal cortex and insula showed stronger negative correlation in the Internet addicts relative to control group (p < 0.001, uncorrected). No significant relationship between functional connectivity strength and current degree of Internet addiction and degree of impulsitivy was seen. Conclusion: This study found that Internet addicts had declined connectivity strength in the orbitofrontal cortex (OFC) and other regions (e.g., ACC, IPC, and insula) during resting-state. It may reflect deficits in the OFC function to process information from different area in the corticostriatal reward network. Application: The results might help to develop theoretical modeling of Internet addiction for Internet addiction discrimination.

Objectives: Adolescence involves a number of developmental processes, as well as unique psychological characteristics and behaviors. An increased rate of internet and game addictions, school violence, and suicide may either represent aspects of adolescence or a psychopathological phenomenon. There is an urgent need to develop software programs that can prevent and resolve adolescent behavioral problems. We applied the mentalization theory to interpret and find solutions for problems faced by adolescent characters in literature. Methods: In Joan Rowling's novel "Casual Vacancy," Sukhvinder is a girl with problems representative of those encountered by modern adolescents; she is a victim of bullying and engages in self-mutilation. We targeted her problematic behaviors as representative of a prementalized state. Results: Born into an upper-class English family with Pakistani origins, Sukhvinder, unlike her siblings, fails her parents' expectations. Whenever she faces a psychological crisis, she regresses into the teleological mode (the most primitive pre-mentalization stage) and regains her sense of self by cutting herself. After her friend's suicide, however, she begins to communicate with her parents and moves toward mentalization. Conclusion: By analyzing Sukhvinder's behavior, we assessed patterns of attachment, empathy, and mentalization, and identified corrective approaches for problematic behaviors. We believe that the presented interpretation may serve as a foundation for the development of models for understanding adolescent deviant behaviors.

This study aims to evaluate the impact of forest therapy on neuro-cognitive, psychosocial, and physiological aspect of adolescent internet addiction risk group. We have classified potential and high risk user group as internet addiction risk group according to the criteria of Korean Internet Addiction Proneness Scale(K Scale). Based on the results of k-scale from the adolescents in metropolitan area from May to July 2013, 25 people were selected as Internet addiction risk group. We have randomized 13 participants joining forest therapy camp and 12 participants not joining one, and analyzed the change of the two groups with Continuous Performance, Kimberly S. Young, Connor-Davidson Resilience, Relationship Change Scale, heart rate variability and cortisol. Statistically significant changes were observedd in neuro-cognitive, psychosocial, and physiological variables, Through this study, we can consider that the therapy healing may relieve the level of internet addiction and can be an alternative to control emotional stability and impulsive behavior.

The purpose of this study is to verify the path of the motivation, the flow, and problem gambling and intervention points. To this end, we verified the mediation effect of the motivation of the users outside sales offices influences the problem gambling through a flow and the moderated mediation effect of the frequency of the use of a bicycle racing tracks in that process. A total of 411 cases were analyzed using surveys conducted for one day on a weekday and weekend (September 13th and 15th 2018) for adults using an outside sales office in Jangan. According to the analysis, the causality of gambling by gambling motivation(amusement, excitement, avoidance, society, money) showed its effect positively by mediating the flow. The adjusted effect of the frequency of the use on the intermediary effect of the motivation ${\rightarrow}$ flow ${\rightarrow}$ problem gambling behavior, which is the main concern of this study, was found to be statistically significant. More specifically, the effect of adjusting the frequency of the use was statistically significant in both paths: motivation/flow and flow/problem gambling. It was also shown that, in the model with excitement, avoidance and social motivation, the adjustment of the frequency was only significant in the causal relationship between the flow and problem gambling. Based on these findings, this study made clinical and policy suggestions for intervention for gamblers and user protection regulations.
