청소년기는 생리적, 정서적, 사회적으로 변화를 겪는 매우 불안정한 시기이다. 이때에 게임은 청소년의 스트레스를 줄여주고, 교우관계를 돈독하게 해줄 수 있는 유용한 매체이다. 그러나 게임의 과도한 이용은 오히려 청소년들의 삶을 피폐하게 만든다. 따라서 본 연구에서는 아버지의 개방적 의사소통이 중학생 자녀의 게임 과몰입에 미치는 영향에서 게임이용특성 중 시간, 기간, 지속정도가 어떠한 매개적 역할을 하는지 확인했다. 본 연구에서는 수집된 자료로 아버지의 개방적 의사소통이 게임이용특성을 매개하여 게임 과몰입에 미치는 영향을 살펴보고자 병렬매개효과를 확인하였다. 이를 위해 SPSS WIN 22.0 프로그램과 Process Macro 3.4 매크로를 사용하여 다음과 같은 분석을 진행했다. 이에 대한 연구결과는 다음과 같다. 첫째, 아버지의 개방적 의사소통은 중학생 자녀의 게임 과몰입에 부적 영향을 미쳤다. 둘째, 아버지의 개방적 의사소통은 중학생 자녀의 평일게임시간과 게임지속시간에 부적 영향을 미쳤다. 셋째, 중학생 자녀의 평일게임시간, 게임연수, 게임지속시간은 게임 과몰입에 부적 영향을 미쳤다. 마지막으로 아버지의 개방적 의사소통과 중학생 자녀의 게임 과몰입의 관계에서 평일게임시간, 게임지속시간은 부분매개효과가 있었다. 이를 통해 중학생의 게임 과몰입을 낮추기 위해서는 개인적 노력뿐만 아니라 가정에서 아버지의 역할이 중요함을 알 수 있다.

The purpose of this study was to investigate the environmental factors that affect the computer literacy of childcare teachers. A survey was conducted to get information about teachers' ICT utilization ability and their physical and educational condition. Binary logistic regression analysis was performed using SPSS 17.0 program on the data of 293 teachers who work in childcare centers in capital area, and the following results were obtained. First, computer-related physical environment and computer training did not affect the teachers' computer literacy. Second, taking computer course had effects on the basic skills, word-processing ability, internet communication ability and computer program utilization. Third, the number of hours of using computers affected the ability to install and maintain computers. Fourth, the purchase of computer-related books and magazines and the number of computer programs they use had an effect on their computer program utilization. These results have significance in that they imply what is needed for improving childcare teachers' computer literacy in terms of institutional support.

The purpose of this study was to examine the effects of adolescents’ game usage on game addiction and the mediation effects of withdrawal symptoms and loss of control. The subjects of the study was 6,499 elementary, middle and high school students included in the panel data from the survey conducted by The National Youth Policy Institute. For data analysis, SPSS WIN 21 and AMOS 21 programs were used to test the structural equation model by examining the relationships among game usage, withdrawal symptoms, loss of control, and game addiction. The results are as followings. First, adolescents’ average daily game playing hours and average daily game playing hours on holidays caused withdrawal symptoms and loss of control, increasing the possibility of game addiction. However, the relationship between the number of years of playing games and game addiction was not mediated by withdrawal symptoms and loss of control. This implies that playing computer games from young age does not necessarily lead to game addiction unless the students show withdrawal symptoms or lose control.

The purpose of this study is to develop an objective instrument to measure ICT utilization ability of day care center teachers and verify its validity and goodness of fit. With the developed scale, the survey was conducted with 297 day care center teachers. As a result, the reliability of all questions was over .6, and the construct validity of the instrument consisting of 20 questions in 4 factors was verified in exploratory factor analysis. As a result of performing confirmatory factor analysis, it was found that GFI=.949, AGFI=.898, and RMR=.029, indicating that the goodness of fit index is sufficient to be used as a measuring model. The scales of ICT utilization ability are composed of 4 factors: Factor 1 is called editing, Factor 2 is program application, Factor 3 is installation and maintenance, and Factor 4 is named communication. With these factors, the measuring device for ICT utilization ability of day care center teachers, which is composed of a total of 20 questions, is confirmed.
