최근 모바일 시장의 급격한 발전으로 인하여 스마트폰 기능 또한 다양해져 사용자 또한 다양한 계층에서 사용되고 있다. 그러나 스마트폰 게임은 유료든 무료든 게임 대부분이 현금을 주고 아이템을 구매할 수 있는 부분 유료화 정책을 실시하고 있기 때문에 구매능력이 없는 청소년도 쉽게 게임 아이템을 쉽게 구매할 수 있는 문제점이 있다. 본 논문에서는 지불능력이 없는 청소년이 온라인게임 상에 물품을 구입할 경우 청소년의 부모에게 게임 아이템 구입 확인 메시지를 게임업체가 전달하여 승인 코드를 전달받아야만 게임 관련 물품을 구입할 수 있는 게임 지불 메커니즘을 제안하고자 한다.

The severity of smartphone dependence among early adolescents, known as the most vulnerable group to smartphone addiction, is increasing. In this study, the factors affecting the smartphone dependence of early adolescents were analyzed by separating into elementary school and middle school students. For this purpose, the 1st data from Korean Children and Youth Panel Survey(2018) was used. The subjects of the study were 2,607 4th grade from elementary school and 2,590 1st grade from middle school. Factors that affect to smartphone dependence of both elementary and middle school students in common were gender, self-esteem, aggression, time spent with parents, and negative parenting attitude. On the other hand, region(city size), economic level, health status, school life satisfaction, and relationship with teachers were significant in the smartphone dependence of elementary school students, but not in middle school students.

The purpose of this study was to investigate the effects of elementary school students' stress and social support on smartphone addiction and school adjustment. Our hypothesis is that stress and social support of elementary school students affects smartphone addiction and school adjustment. In addition, the study model assumes that stress and social support of elementary school students were mediated by the effects of smartphone addiction. Analysis results found that elementary school students' stress affects smartphone addiction and school life adaptation, and social support influences school life adaptation. Elementary students' smartphone addiction has little influence on school life adjustment. Stress in elementary school students has a strong influence on smartphone addiction, social support, and adaptation to school life. In other words, higher stress levels results in higher frequency of use of smartphones, which may directly affect smartphone addiction and the ability to adapt to school life. The effects of stress and social support of elementary school students on school life adaptation and smartphone addiction were ultimately indirect. Based on the research results, this study suggests policy implications for elementary school students' addiction to smartphone and ability to adapt to school life.

In this study, the personality type of youths was divided into 4 areas: Open, Blind, Hidden and Unknown, and the four different types were analysed according to the impact on smartphone addiction. The survey was conducted on 406 middle school students in Jeonbuk province to assess the relationship between smartphone addiction of youth and the personality type. The results of this study are as follows: First, the difference of smartphone addiction in youth between genders is not large, but males were largely affected by tolerance, while females by difficulty of daily living. Second, the differences of smartphone addiction between grades found that difficulty of daily living and tolerance had a statistically significant impact. Third, the result of co-relationship between the Johari window type of mind and smartphone addiction showed that blind type and unknown type had a statistically significant positive relationship but open type had a negative impact. Finally, analysis of variables about whether a type of mind affected smartphone addiction showed that there was a relationship. The most serious type of addiction to smartphones showed in hidden type and unknown type. Therefore in developing programs to treat smartphone addiction it should seek specific measures to help these groups.
