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.

This study suggests a proper studying direction of research on relationship addiction problem. And it presents fundamental research data by analysing domestic research trends of relationship addiction among various crises of people have addiction problem. For analysis of trends on relationship addiction, I searched almost all master's and doctoral dissertations and academic journals which were studied on "addiction", "relationship addiction", "addiction relationship" from 2005 to 2019 in Korea. Also I have surveyed various publications in the data base of Research Information Sharing Service, academic research data base, the National Assembly Library and the National Central Library in Korea. And for the reasonable results, I have studied the research according to 4 steps such as "collecting data and analyzing precedent research", "building analysis criterion", "cording and analysis", "making conclusion and suggesting the development direction" The results of this study are like these. The total number of researches on relationship addiction is 67. The object of those studies were limited adult's or undergraduate students's relationship addiction. So it is necessary that the fields of relationship addiction research are expanding gradually. And the research shows that the relationship addiction problem is directly related with sexual prostitution. Therefore, there are enough needs to study more in diverse, different point of view. Also it is suggested that the proper analyses methodology of relationship addiction shoud be used and new analysis criterions should be developed. In this study, the necessity of further more study is proposed in various ways of methodology about the relation of social problem and relationship addiction. And from this study, it is proved that expending the objects and fields of the study on relationship addiction, the factors analysis on addiction, study models of addiction must be necessary to be studied.

Objectives : To develop measurement scales of Internet addiction, and propose a Korean Internet Addiction Index (K-IAI) and classification criteria for Internet addiction from the threshold scores developed. Methods : The identification of the concept of 'Internet addiction' was based on the literature review. To select the scales, an exploratory factor analysis was applied. A construct validation was tested by a confirmatory factor analysis (CFA) with a structured equation model (SEM). In testing the validity of the classification criteria, ANOVA and non-recursive models with SEM were applied. Results : Out of 1,080 questionnaires distributed, 1,037 were returned,; a response rate of 96%. The Cronbach-$\alpha$ of all items was over 0.75. Using an exploratory factor analysis in the condition of a 6 factor constrain as the study model proposed, 23 of the initial 28 items were identified. In testing the discriminant and convergent validity of the selected 23 scales using CFA with SEM, the Internet addiction model explained about 93% of all variances of the data collected, and all the latent variables significantly explained the designated scales. A K-IAI was proposed using the T-scores of the sum of all factor averages. In the classification of users, the basic concept was a twostandard deviation approach of the K-IAI as the criteria of MMPI. The addiction group had a score ${\geq}70$ in the K-IAI, the pre-addiction group between ${\geq}50$ and <70, and the average user group <50. The Internet use times of the classified groups were statistically different in the ANOVA and multiple comparisons. Conclusions : The K-IAI is a reliable and valid instrument for measuring Internet addiction. Moreover, the taxonomy of the groups was also verified using various methods.

Purpose: This study is a descriptive correlation study to identify how factors such as motivation to learn, school adaptation, self-control, and self-esteem influence the degree of Internet game addiction and to provide basic data for nursing interventions for male middle school students. Methods: The subjects of this study were 418 male students in lst, 2nd and 3rd grade at three middle schools located in Ulsan. Data were collected from May 1, 2011 to May 31, 2011 and analyzed through descriptive statistical methods, such as the t-test, ANOVA, Sheffe's test, Pearson correlation coefficient and multiple regression analysis, via SPSS 18.0 program. The study's structured questionnaire was composed of 25 items of 'the Motivation to Learn Scale', 41 items of 'the School Adaptation Scale', 20 items of 'the Self-Control Scale', 10 items of 'the Self-esteem Scale', and 20 items of 'the Internet Game Addiction Scale'. Results: 163 students (39.0%) belonged to the non-addiction group while 255 students (61.0%) fell into the addiction risk group. The addiction risk group showed a higher degree of addiction than ones in the non-addiction group. The addiction risk group's average scores for motivation to learn, school adaptation, self-control, and self-esteem were lower than those of the non-addiction group. The statistically significant factors (p<.05) that increase the chance of addiction were grade, family atmosphere, self-control, trading of online game items, and the amount of time playing online games. Conclusion: On the basis of the findings of this study, it is suggested that; qualitative research on the routes of addiction be conducted to find out ways to prevent and nurse addicted students; considering the fact that the average age of Internet users is getting lower and lower, a study targeting primary school students be implemented; since the influences of the variables covered in this study turned out to be relatively low, other factors, especially environmental factors, should also be investigated.

Addiction can be largely divided into two categories. One is called medium addiction in which medium itself causes an addiction. Another is called cause addiction that brings addiction through combination of sensitive self and latent personal action. The medium addiction involves addiction phenomena directly caused by illegal drugs, alcohol and various other chemicals. The cause addiction is dependent on personal sensitivities as a sensitive problem of personal and includes cyber addictions such as shopping, work, game, internet, TV, and gambling. In this paper we propose two-dimensional addiction model that are equivalent to using an R-L-C series circuit of Electrical circuit and a Spring-Damper-mass of mechanical system. We also organize a Duffing equation that is added a nonlinear term in the proposed two-dimensional addiction model. We represent periodic motion and chaotic motion as time series and phase portrait according to parameter's variation. We confirm that among parameters chaotic motion had addicted state and periodic motion caused by change in control coefficient had pre-addiction state.

The objective of this study was to investigate the relationship between addiction to online games and carpal tunnel syndrome (CTS) in college students. A total of 377 (205 male and 172 female) college students completed an online game addiction scale, a Symptom Severity Scale (SSS), and a Function Status Scale (FSS) for CTS. It was found that five (1.3%) students were diagnosed with an online game addiction, 74 (19.6%) students were diagnosed with a pre-addiction to online games, and 298 (79.0%) students were diagnosed as being average users. The pre-addiction group had significantly higher scores on the SSS than did the average user group (p<.05). The average user group scored significantly lower than did the online game addiction group (p<.05). Symptoms of wrist pain and hand numbness in the daytime were common in the addiction group. There were statistically significant but poor positive relationships between the online game addiction scale and the SSS (r=.312, p<.01), and between the online game addiction scale and the FSS (r=.149, p<.01). The information about online game addiction and CTS identified in this study could contribute to the prevention of online game addiction and CTS in college students.

Consumer researchers found that compulsive buying was a part of a category of compulsive consumption that was interrelated to addictive and repetitive behaviors. The present study empirically examined the co-morbidity of compulsive buying and Internet addiction among e-commerce users in terms of consumption disorders. Although the prevalence of Internet use and on-line sales remarkably increase in recent years, almost no study examines on-line compulsive buying behavior. This study explored the link between compulsive buying and Internet addiction among e-commerce users, and investigated the characteristics of on-line shoppers with respect to two forms of compulsive consumption, which were divided into compulsive buying and Internet addiction. Additionally, factors that related to compulsive buying behaviors among e-commerce users were also examined. The present research was conducted using a convenience sample of 394 young adults between the ages of 20-30, and the Faber and O'Guinn's DSCB scale and the Widyanto's Internet addiction scale (IA) were used. Confirmatory factor analyses were utilized to evaluate the structure of the DSCB and IA, and a Probit model was used to examine determinants for the compulsive buying behaviors of e-commerce users. E-commerce users were classified into four groups; high compulsion and high addiction, low compulsion and low addiction, high compulsion and low addiction, and low compulsion and high addiction. Consumers with high compulsion and high addiction spent higher amounts of money on their on-line purchases and were frequently connected with the Internet compared to the three other consumer groups. Consumers with compulsive buying behaviors were also found to have significantly greater Internet addiction tendencies than typical buyers. Compulsive buyers were more likely to engage in Internet addiction and the number of purchasing via on-line shopping mall, and had higher materialism. Policy implications and suggestions for consumer education programs were discussed.

Purpose - This study investigates the effects of thought suppression on depression and uneasiness among college students likely to be influenced by smart phone addiction. Research design, data, and methodology - A total of 151 valid questionnaires were collected. The following analyses were conducted using SPSS 19.0 and AMOS 19.0: frequency, descriptive statistics, correlation, simple regression, and multiple regression. Results - Smart phone addiction increased uneasiness, depression, impulsiveness, and aggression. Moreover, uneasiness, depression, impulsiveness and aggression from smart phone addiction, had a negative influence on psychological wellbeing resulting in potential delinquent behavior. In addition, the addiction treatment relied heavily on drugs; therefore, such psychological treatment should be strengthened to control intermittent addiction. Conclusions - The results indicate that various kinds of research are needed to investigate personality and environmental factors that influence smart phone addiction. Additionally, studies on lessening smart phone addiction and living healthy lifestyles are needed. Moreover, psychological rehabilitation and treatment should be developed to lessen the rebound effect after thought suppression, to verify the effects of clinical application, and to prevent intermittent addiction.
