Reckless use of the Internet by children is a barrier to daily life and has a negative impact on children's physical, psychological and relational aspects. But more and more children depend on the Internet. Thus, the study conducted a meta-analysis to examine the effectiveness of group programs that involve Internet addiction among elementary school students. The study analyzed 18 studies of a local Internet group counseling program. First, the overall effectiveness of Internet-dependent group programs that cause Internet addiction reduction in elementary school students is shown to be g=0.90, indicating that group counseling programs are effective in reducing Internet addiction and changing related variables. Second, as a result of verifying differences between groups, there were differences in effectiveness in voluntary participation motivations. Therefore, intervention by elementary school students requires preventive training for smart phones so that voluntary participation can occur, and education for parents to develop autonomy for children to use smartphones properly. And rather than making these efforts limited to smart phones, IT retriever education needs to be organized.

This study analyzed 817 articles published in Korean professional journals over the past three years, from 2020 to 2022, using text mining techniques to identify trends in addiction research in Korea and explore development directions. The analysis results are as follows. First, as a result of the analysis of the top keywords, online addiction studies such as smartphones, games, Internet, gambling, and relationship addiction were prominent as the top keywords. Second, as a result of TF-IDF analysis, many addiction studies related to behavioral addiction such as smartphones, games, the Internet, and work addiction have been conducted over the past three years, and in particular, there are many studies on addiction problems such as smartphones, games, and the Internet that have not yet been clinically diagnosed as addiction problems. This is the same as the result of word frequency analysis, and it can be interpreted that recent studies have been remarkably conducted on more diverse addiction problems. Third, the 2-gram analysis shows that words that mainly correspond to behavioral addiction, such as smartphones, games, and the Internet, appear side by side with the keyword addiction, and among them, words paired with smartphones are mentioned a lot in research papers and are being studied. Fourth, as a result of the CONCOR analysis, there were five clusters: a study on universal addiction issues such as alcohol use disorders and the Internet, a study of recovery on drug and gambling addiction, a study on mobile devices and media addiction, a study on the latest trends related to behavioral addiction, and other addiction issues. Finally, based on the results of this study, a direction for future addiction-related research was suggested.

In this paper, voice analysis is performed to propose a quantitative indication of withdrawal symptoms of smartphone addiction, applied to 20 males in their 20s. For this, their smartphones were confiscated during a certain period, and we collected samples of voice signals from them before and after that period. The pitch variation and intensity magnitude of the voice samples were used in the experiment to investigate their anxiety resulted from withdrawal symptoms. The experimental results showed an increase in pitch variation from 90% of samples, and a decrease in intensity magnitude from 95% of them. Finally, we carried out a study to find a statistical significance from the extracted experimental results through statistical analysis.
