Objective: The purpose of this study is to investigate the moderating role of Ego-Resilience between Peer Attachment and Mobile Phone Dependency in late adolescence. Methods: The participants were 2056 third year high school adolescents (1,041 boys and 1,015 girls) from the Korea Youth Panel Study (KYPS), a national representative of Korean Children and adolescence. Hierarchical Regression was used for data analysis. Results: First, the correlation between peer attachment, ego-resilience and mobile phone dependency were all significant. Second, ego-resilience takes the role of moderator for mobile phone dependency. In detail, ego-resilience relieves the mobile phone dependency caused by 'peer relationships' or 'conflict in peer relationships. Conclusion/Implications: Ego-resilience was found to control the relationship between peer attachment and mobile phone dependency. Therefore, in order to lower the dependence of mobile phones in adolescents with low peer attachment, a program that can enhance ego-resilience is needed.

Objectives : The purpose of this study was to identify the influencing factors of cell phone addiction in adolescents and to construct a cell phone addiction model for adolescents. Methods : Data from the 5th Korean Child-Youth Panel Survey (KCYPS) was analyzed with the SPSS 20.0 and 23.0 AMOS programs. Results : According to the model of this study, depression had statistically significant direct effects while emotional characteristics and parental abuse had statistically significant indirect effects on cell phone addiction in adolescents. School life adjustment had statistically significant direct and indirect effects on cell phone addiction in adolescents. Conclusions : Based on the results of this study, it is necessary to develop prevention and intervention programs to combat cell phone addiction in Korean adolescents.

This study investigated firstly the cellular phone addiction tendency according to the classification of addiction, dependency, non-addiction and predicting factors of cellular phone use and secondly the psycho-social characteristics of cellular phone use by adolescent'. Participants were 368 students of academic and occupational high schools in Seoul. A prediction model of cellular phone addiction tendency was developed and show떠 that there were significant effects of cellular phone use-time, use-motives, counseling experience, impulsiveness, and depression on cellular phone addiction.

Nowadays, due to the popularization of mobile phone, the functions and using manners of mobile phone have been varied. According to Korea National Statistical Office, the numbers of domestic mobile phone user were 30 million at the end of March 2002. A survey was conducted to investigate the various using manners of mobile phone, especially the young ones from 15 to 28 years old. Two hundred and sixty people participated in this study. According to the result of this study, text messaging was one of the major functions of the mobile phone for the young people. Also, continuous and repetitive use of small key pad of mobile phone for text messaging could cause the repetitive strain injury on hand, especially fingers.

This paper presents web service and service on mobile phone about research on virtual URS(Ubiquitous Robotic Space). We modeled the URS. Then, we find the location of robot in the virtual URS on web and mobile phone. We control the robot view with mobile phone. This paper addresses the concept of virtual URS and introduces interaction between robot in the virtual URS and human using web and mobile phone service. Then, this paper introduces a case of service on mobile phone.

공학의 기본 원리 학습을 위해서는 원리 그림이나 도표와 같은 콘텐츠의 사용이 필요하다. 하지만 시간과 공간의 제약으로 학습이 불충분하고, 편리성과 멀티미디어 콘텐츠를 갖추지 못하면 학습의 효과도 떨어지는 문제점이 있다. 최근 Smart Phone 사용자가 증가하고, Smart Phone을 이용한 교육프로그램을 제공하여 이동 중에도 공학의 기본 원리와 같은 학습이 필요한 시점이다. 본 논문에서는 열역학의 법칙 등 열역학에 관한 학습 콘텐츠를 Smart Phone에서 구현하고자 한다. 실제 Web 서버를 통하여 무선 인터넷 통신망에서 제공되는 열역학의 교육 공학적 도표, 애니메이션, 그림, 등을 Smart Phone에서의 설계하고 구현한다. 본 연구는 교육공학과 학습 프로그램 제공을 통해 모바일 원격교육 발전에 기여할 것이다.

One of the major factors influencing the phenomenal growth of the smart phone market is the active development applications based on open environments. Despite difficulties in finding and downloading applications due to the small screens and inconvenient interfaces of smart phones, users download applications nearly every day. Such user behavior patterns indicate the significance of smart phone applications. So far, studies on applications have focused mainly on technical approaches, including recommendation systems. Meanwhile, the issue of culture, as an aspect of user characteristics regarding smart phone use, remains largely unexamined throughout the world. Hence, the present study attempts to analyze the highest ranked smart phone applications downloaded and paid for that are ranked the highest in 10 countries (Korea, Japan, China, India, the UK, USA, Indonesia, Canada, France, and Mexico) and we then derive the CDSC (Cultural Dimensions Score of Content) for these applications. The results derived are, then, mapped to the cultural dimensions model to determine the CISC (Cultural Index Score for Country). Further, culturally significant differences in smart phone environments are identified using MDS analysis.

The purpose of the present study was to test the impact of depression on mobile phone dependency among elementary school students, to test the mediating effect of self-esteem between depression and mobile phone dependency, and to draw out theoretical and practical implications in terms of preventing or reducing mobile phone dependency. Based on previous studies, a longitudinal research model between the aforementioned three variables has been identified. The present study analyzed the 4th, 5th, and 6th wave data from Korea Children and Youth Panel Study 2010 (KCYPS 2010). The major results were as follows. First, depression could have a significant negative effect on self-esteem. Second, self-esteem could have a significant negative effect on mobile phone dependency. Third, the influence of depression on mobile phone dependency was not significant. Fourth, gender could be a significant moderating variable between depression and self-esteem. Finally, a number of implications of these findings were also discussed.

This study aimed to analyse the effects of self-control and impulsiveness of college students on smart phone addition and whether self-esteem has mediating effects on them. For the purposes, this study interviewed 4-year college students in Gwangju City with the use of a questionnaire and 314 copies of the responses were used for a final analysis. The data collected was analysed with the use of SPSS 22.0 and the results are presented as follows: First, behavior impulsiveness has a positive effect on self-esteem and smart phone addiction. Second, self-esteem had a positive effect on smart phone addiction. Third, it was discovered that behavior impulsiveness had a positive effect on smart phone addiction through an analysis of mediating effects while self-esteem had an indirect effect on it. Therefore, it was suggested that more care should be paid on smart phone addiction and development of programs against it should be facilitated.
