  • Objective: The purpose of this study was to investigate the effects of empathy, aggression, and self-esteem on social preference and social impact in preschoolers. Methods: The participants were 307 five year olds who were recruited from day care centers and preschools located in Seoul and Gyeonggi province. Social preference and social impact was measured with peer nominations. Empathy and aggression were measured by teacher ratings. Moreover, self-esteem was asessed using self-reports. The data was analysed using Pearson correlation and hierarchial regression. Results: Findings indicate that social preference is associated with empathy, however, social impact was associated with physical as well as relational aggression. Conclusion/Implications: The findings suggest that the practice of physical and relational aggression may be related with peer status as early as preschool.

  • This study examined the mediation effects of covert narcissism on the relationship between game addiction and aggression. For this study, 578 middle school boys in Chungcheong areas were included in the analysis. The results are as follows. First, correlation analyses showed that game addiction was positively correlated with covert narcissism and aggression. In addition, covert narcissism showed positive correlation with aggression. Second, step-wise regression analyses were conducted to examine the relative size that sub-factors of game addiction and covert narcissism explained aggression. It could be known that three factors of game addiction(tolerance, disregard of everyday life, damage of control) and two factors of covert narcissism(exploitation/self-centeredness, oversensitivity/vulnerability) showed significant explanatory power for aggression. Third, the Structural Equation Model was designed in which factors of game addiction and covert narcissism with significant explanatory power for aggression were included. Covert narcissism was found to partially mediate the influence of the boys' game addiction on aggression. Finally implications of this study and directions for future research were discussed.

  • 기존의 신용카드 등이 최근에는 암호 기능을 갖춘 스마트카드로 대체되고 있다 그러나 스마트카드의 제한적인 연산기능으로 인하여 탑재되는 암호 알고리즘을 고속화하여 탑재해야 하는데, 이렇게 고속화된 암호 알고리즘은 사이드 채널 공격(Side Channel analysis)에 취약점을 갖는다. 암호 알고리즘의 동작 중에 시간차, 전자파, 전력 등 부가적으로 얻어지는 정보를 분석하는 사이드 채널 공격은 이론적으로 안전성이 증명된 알고리즘에서도 구현상의 문제로 인하여 공격이 가능하기 때문에 그 위험성이 매우 높다. 본 고에서는 2003년 신규 정보보호제품 평가대상으로 확대된 스마트 카드의 안전성 평가방안에 대하여 설명하고 스마트카드 상에서 공격 가능한 사이드 채널 공격을 타이밍 공격, 오류삽입 공격, 단순/차분 전력분석 공격으로 나누어 기술하고 이러한 공격에 대한 대응기법을 소개한다.

  • This study was conducted to ascertain the mediating effects of aggression in high school students' relationship with smartphone overuse and cyberbullying. Data were collected from 328 high school students in K city using self-report questionnaire. The collected data were analyzed using SPSS 22.0 and AMOS 22.0. The results show that cyberbullying has a positive correlation with smatrphone overuse(r=.321, p<.001) and aggression(r=.397, p<.001). Smartphone overuse had a direct effect on aggression(${\beta}=.195$, p=.014) and aggression had a direct effect on cyberbullying(${\beta}=.260$, p=.007). In addition, the mediation effects of aggression on the relationship between smartphone overuse and cyberbullying were confirmed(${\beta}=.051$, p=.007). In order to reduce cyberbullying in high school students, it will be necessary to develop cyber ethical awareness education programs to reduce aggression as well as regulations on excessive use of smartphones.

  • In the present study, we studied the change patterns of adolescents' overt aggression during the middle school 2nd to the high school 1st grades and the effects of ecological factors on the change. For the research goals, we applied multi-level models to the Korean Youth Panel data. Results showed that adolescents' overt aggression decreased significantly during the period. Gender(males recoded as 1) and self-control had negative effects on the initial status(middle school 2nd grade) while the number of delinquency peers had a positive effect. On the other hand, gender and self-control showed positive effects on the change rate. The major strengths of the research are the study of various ecological factors and the longitudinal design. Few studies of adolescents' aggression have incorporated these methodological and substantive characteristics.
