Purpose: This study was conducted to review physiological mechanisms of internet addiction and to construct a theoretical framework for cognitive behavioral therapy for internet addicts. Methods: We searched for relevant literature in the PubMed and RISS databases using the terms "internet addiction", "internet game addiction", "internet abuser", and "online game". Only English, full-text articles published from 2000 to 2015 were included in this review of physiological indicators of internet addiction. Finally, 12 articles were selected for review. Results: The theoretical framework developed based on the review proposes that excessive internet use itself may induce physiological stress responses with an increase of stress-related hormones and neurotransmitters. Prolonged abnormal responses of these physiological features produce negative structural and functional changes in the prefrontal cortex, which is mainly involved in cognitive and executive functions. These changes may result in decreased cognitive function. As a stressor, excessive internet use leads to transforming voluntary use into involuntary, habitual use and thus promotes the development of internet addiction. Conclusion: The proposed theoretical framework encompasses cognitive processes that may contribute to the effects of internet use-induced physiological stress on internet addiction. We believe that this framework has important implications for developing cognitive behavioral strategies for internet addicts.

본 연구는 청소년을 대상으로 학습 목적 이외의 인터넷 사용시간을 파악하고, 인터넷 사용시간에 따른 주관적 상태를 파악하여 이들의 상호 관련성을 파악하고자 하였다. 2016년 청소년건강행태온라인조사를 이용하여 인터넷 사용시간에 따른 주관적 상태의 교차비와 95% 신뢰구간을 이분형로지스틱회귀분석을 통해 산출하였다. 주관적 건강인지와 주관적 구강건강인지에서는 학습 목적 이외의 인터넷사용을 하지 않는 경우에 비해 인터넷 사용시간이 길수록 주관적으로 불건강하다고 느끼는 경우에서의 각각의 교차비가 유의하게 증가하였다. 주관적 체형인지에서도 인터넷사용시간이 길수록 살이 찐 편이라고 느낄 교차비가 유의하게 증가하였다. 주관적 행복은 인터넷을 300분 이상 사용하는 경우 주관적으로 불행하다고 생각할 교차비가 1.19배(CI=1.10-1.30) 높게 나타났다. 학습 목적 이외의 장시간의 인터넷 사용이 청소년 건강과 행복에 부정적인 영향을 미칠 수 있으므로 인터넷 사용에 대한 권장시간이 필요할 것으로 생각한다.

The purpose of this study was to research the actual state of mother's internet use and to explore the possibility of the internet use as a social support. The affect of mother's internet use on maternal efficacy is also examined. The Subjects were 250 mothers, who have their first child under 8 years old, in Seoul and Ilsan. Data were gathered through questionnaires. As predicted, mother's internet use was popular among young mothers. And, the main reason of internet use of mothers was to find some information on parenting and nurturing child. Moreover, mothers believed that they could get some social support from using internet in terms of informational, instrumental, and emotional service. However, it should be noted that mother's perceived level of support was significantly different, depending on mother's age, level of mother's education, household income, and the age of the first child. It was also found that mothers who received social support from internet showed higher material efficacy. Thus, we believe that internet use could be a new source of social support for the mothers of young children.

The purpose of this study was to analyze consumers' perceived risk and information search behaviors in internet shopping. For this purpose, survey was conducted on 302 consumers in their 20s and 30s who had internet shopping experience. This study found that consumers' perceived risk was significantly related to their gender, educational level, income, credit card use, period of internet un, number of internet shopping experiences, and purchased product. Consumers' search behaviors were also significantly affected by gender, age, educational level, income, period of internet use, and purchased product. In addition, a higher level of consumers' perceived risk was significantly related to the amount of information search on product attributes themselves rather than on general information search such as the number of sites or the number of brands.

The purpose of this paper is to investigate the diffusion process of mobile internet use in Korea and to explore the determinants driving MIU. A survey was conducted to collect data to empirically assess the research model. In total, 543 usable responses were collected using a questionnaire derived from previous research. Both the structural equation model and partial least squares were used to study the model concerning different user groups. Findings, The results indicate that there are significant differences in the users' perceptions of mobile internet usage during its different innovation diffusion stages. Of the determinants, perceived enjoyment is the most important predictor of mobile internet use. In addition to motivating users by making services more enjoyable, the findings suggest that practitioners should take the differences of adopter groups into account. Making the mobile internet easy to use and compatible with users' lifestyles would promote the use of technology as well.

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.
