최근 스마트폰이 대중화 되면서 스마트폰을 사용하는 사용자의 계층이 다양화되고 있다. 그러나 스마트폰을 사용하는 사용자 계층 중 청소년이 다른 계층보다 스마트폰 게임에 쉽게 중독되어 다른 일상 생활이 힘든 상황이 발생하고 있다. 본 논문에서는 스마트폰 게임을 통해 일상 생활이 불가능한 청소년을 대상으로 게임 사용을 강제적으로 조절할 수 있는 인증 프로토콜을 제안한다. 제안 프로토콜은 사용자의 게임 시간과 접속 횟수 등의 정보를 이용하여 게임 사용을 자제하도록 함으로써 사용자의 게임중독을 예방하는 것을 목표로 하고 있다. 또한, 청소년이 온라인 게임 상에 물품을 구입할 경우 청소년의 부모에게 게임 아이템구입 확인 메시지를 전달하여 게임 사용을 제한한다.

스마트폰은 휴대전화에 인터넷통신, 정보검색, 메일 송/수신, 음악 및 동영상 재생 등 컴퓨터 지원 기능이 추가된 기기로, 휴대전화의 경우 제조할 때 탑재된 기능만을 사용하는데 반해 스마트폰은 사용자의 기호에 따라 마음대로 어플리케이션을 추가로 설치하여 사용할 수 있다는 특징을 가진다. 우리나라는 2010년부터 스마트폰 사용이 대중화되기 시작하면서 스마트폰 사용인구가 급격히 증가하여 우리의 일상생활과 밀접한 관계를 가지며 영향력을 넓혀가고 있다. 하지만 스마트폰이 활성화되면서 스마트폰을 이용한 보안 위협의 발생도 증가하게 되었다. 이에 전 세계적으로 스마트폰 보안을 위한 다양한 연구 및 대응활동이 활발히 진행 중에 있다. 이와 관련하여 스마트폰 보안 표준화의 필요성을 인식하여 국제표준화를 추진하고 있는 ITU-T SG17에서의 스마트폰 보안 표준화 동향에 대한 정보를 제공하고자 한다.

This paper is about an analysis of the result of the survey which is how the use of smartphone affects the creative personality, focused on 4th and 6th grade in Elementary school, by smartphone addiction self-diagnosis and creative personality test. As a result of the analysis, 6th graders were influenced by their possession of smartphone and the degree of one's smartphone addiction on their creative personality. However, the usage period of smartphone did not turn out to affect their creative personality. In addition, none of the factors above, related to students' smartphone usage, influenced the creative personality of 4th graders. Particularly, there was a negative correlation between the level of students' smartphone addiction and the creative personality and it was found that whether the students own a smartphone or not played a crucial role in creative personality rather than the usage period of smartphone. Therefore, students should be properly educated how to use smartphone appropriately and to prevent them from smartphone addiction in order to improve creative personality which is one of the core competences in 21st century.

본 연구는 스마트폰 중독과 관련된 다양한 분석을 위한 스마트폰 사용 앱과 관리자 웹을 개발하고자 한다. 연구방법으로 이전 연구에서 중요한 변수로 작용되었던 '화면 켠 횟수', '실사용시간-인지사용시간' 변수를 분석할 있도록 적용하여 스마트폰 사용시간, 사용량, 사용 앱, 화면 잠금을 해제한 횟수 등 다양한 데이터 수집이 가능한 앱을 개발한다. 관리자 웹은 수집된 데이터를 저장, 분석할 수 있는 공간으로 사용할 것이다. 앱에서 수집된 데이터는 서버에 전송한 후, 시각화 분석 기능을 제공하는 관리 프로그램으로 개발하여 스마트폰 중독 연구에 사용한다. 향후 데이터 수집과 사용 목적에 동의한 사용자를 모집하여 데이터를 수집하고 스마트폰 사용 패턴, 데이터마이닝, 중독 등과 관련된 다양한 분석을 할 것이다. 이를 통해 보다 정확하고 효과적인 스마트폰 중독 진단이 가능해질 것과 나아가 스마트폰 중독 치료방안 연구에 기여할 것으로 기대한다.

The aims of this study are to analyse how smartphone affects (1)self-control and (2)self-directed learning ability of middle-school students, and also affect (3)self-directed learning ability by mediation of self-control. For these aims, this study used Seoul Educational Longitudinal Study panel data which was conducted in 2015, and conducted multi-group comparisons using structural equation modeling analyses. In analysis of smartphone effects, the use of smartphone of students was divided into 'for entertainment' and 'for learning', and also their first time of smartphone use was considered(elementary vs. middle school). Results indicated that while 'smarphone use for entertainment' was related negatively with self-control and self-directed learning ability of students, 'smarphone use for learning' was related positively, regardless of when smartphone was first used. Also, while 'smarphone use for entertainment' was related negatively with self-directed learning ability by mediation of self-control, 'smarphone use for learning' was related positively.

This study examined effects of smart-phone addiction on the youth's sociality development empirically by questionnaire survey. To conduct this study, 339 high school students participated in the survey. The major findings of the study were as follows; Smart-phone addiction had a significant influence on sociality development in negative way. Specifically, sub-domain of smart-phone addiction(disturbance of adaptive, virtual life orientation, tolerance) affect on sociality development in negative. Interesting, Smart-phone using time affect on sociality development in positive. The implications of these results for research, practice and future directions were also discussed.

Objective : The purpose of this study was to investigate the difference between smartphone addiction and sensory processing ability depending on the time of smartphone usage by at risk of smartphone addiction. Methods : Participants of this study were 124 toddlers in a The data collection period was from September 2019 to December 2019. Measurements in this study included a questionnaire on general information about the subject, a smartphone addiction scale, and a short sensory profile. Methods for the data analysis included descriptive statistics and an independent t-test using SPSS 22.0. Results : There were significant differences between groups depending on smartphone usage time in terms of total smartphone addiction, salience, impulse-compulsive use, withdrawal, tolerance, and interpersonal conflict among toddlers. There were also significant difference in sensory processing ability between groups according to the total Short Sensory Profile score (and in all sub-domains; p=.000 ~ .042). Conclusion : This study found that there was a difference in smartphone addiction and sensory processing ability depending on the smartphone usage time of toddlers at risk of smartphone. It is meaningful because it raises the need for education on the use of smartphones by toddlers.

Smart phones play a significant part in the evolution IT industry. In domestic market, smart phones have grown rapidly. However, until today, precedent studies on smart phones, particularly about the reason why consumers use smart phones are uncommon. Thus, in this study we adopted IS continuance and habit theory to study smart phones' use behavior. The results reveal that perceived usefulness and perceived ease of use, satisfaction of smart phone usage, continuous use, and habit showed the causes and effects relationships. The results indicated that perceived usefulness and perceived ease of use had a positive effect on smart phone user satisfaction. Moreover, smart phone user satisfaction had a positive effect on the smart phone habits and explorative use. However, smart phone user satisfaction showed insignificant effect toward exploitive use. That is, satisfied users regularly use the smart phone but need to formulate habit of use, and then influence exploitive use. Habit showed a positive effect on both exploitive use and explorative use, Finally, we found that users are likely to pay more attention on new features of smart phones while they are using the devices.

A survey was conducted to investigate the association between smart phone use and smart phone addiction in 515 dental hygiene college students. Statistical analyses were conducted using the PASW 18.0 program for Windows. Statistical significance was accepted when p<0.05. The association level was confirmed high in the cases of wide network of friends, and in the provincial areas. The independent parameters that negatively affected smart phone addiction were the wide network of friends, long duration of smart phone use, study attitude, and poor adaptability to campus life.
