The purpose of this paper was to verify the mediated effect of grit in the relationship with the effect of youth social support on aggression. To this end, data from the 2018 Children and Youth Panel (KCYPS) survey were used, and 2,590 first-year middle school students were selected and analyzed. As for the analysis method, Baron & Kenny's regression analysis and Sobel Test were performed. As a result of the main analysis, first, it was found that grit had a partial mediating effect in the effect of parental support, a sub-factor of social support of adolescents, on aggression. Second, it was found that grit had a partial mediating effect in the effect of friend support, a sub-factor of social support of adolescents, on aggression. Third, it was found that grit had a partial mediating effect in the effect of teacher support, a sub-factor of social support of adolescents, on aggression. Based on the above research results, various program development and policy alternatives that can reduce youth aggression and improve grit were suggested.

This study aimed to verify the effects of parental chid-rearing attitudes on adolescents' aggressiveness and the mediation effects of peer attachment. To this end, the 7th year data (2016) (4th grade to the first year of high school) of Korea Children & Youth Panel Survey (KCYPS) were used. The results of this study are as follows: First, the correlations between child-rearing attitudes, aggressiveness, and peer attachment variables were confirmed. Second, parental child-rearing attitudes significantly affected adolescents' aggressiveness. Third, peer attachment showed some mediation effects in terms of the effects of parental child-rearing attitudes on adolescents' aggressiveness. For the significance verification of the mediation effects, the Sobel test was carried out. The results of this study are meaningful as empirical foundation. Based on the study results, this study suggested the need of education programs for parents and peer attachment consolidation programs for adolescents in relation with social welfare mediation practice.

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.

The purpose of this study is to examine the relationship between rejection sensitivity and reactive aggression among college students, as well as to determine the mediating effects of self-concept clarity and hostile attribution bias on the relationship between rejection sensitivity and reactive aggression. A self-report questionnaire was conducted online for the purpose of gathering data from university students aged 18 years and older. A total of 250 participants were included in the analysis. SPSS 27.0 was used for data analysis to check the basic statistics of the variables, frequency analysis, reliability analysis, and correlation analysis. In addition, the model fit was checked using Amos 21.0, and the bootstrapping method verified the significance of the indirect effect. The results of this study are as follows. The results of this study are as follows. First, rejection sensitivity positively affects reactive aggression through self-concept clarity. Second, rejection sensitivity increases the hostile attribution bias, leading to an increase in reactive aggression. Third, rejection sensitivity positively influences reactive aggression in an indirect way by sequentially affecting self-concept clarity and hostile attribution bias. These findings have implications as they identify psychological factors that affect reactive aggression in college students. This suggests the importance of utilizing psychological interventions to address reactive aggression associated with social problems, such as crime, and provides a foundation for both treatment and prevention. Finally, implications for further research and limitations of this study are suggested.

This study is to investigate the difference of depression and aggression according to lifestyle habits in 135 patients with coronary artery disease. The survey was conducted from May 13 to May 15, 2019. In order to investigate the difference of depression and aggression according to lifestyle, independent sample t-test and one-way ANOVA were conducted. Post-hoc analysis was conducted when there was a difference between depression and aggression. The results of the analysis showed that the group with relatively high smoking and drinking was high in physiological depression and the group with active participation in exercise and dietary control showed low physiological depression. The group with more alcohol intake showed higher level of verbal aggression, physiological aggression, and aggressive attitude than the group without alcohol. The group that participated actively in physical activity showed lower physiological aggression and aggressive attitude than the group without active aggression. It was found that the group that participates hard in dietary control is less aggressive than the group that does not.

This study was conducted to verify the mediation model of private self-consciousness on game addiction and aggression. Data from 439 boys were included in the analysis. The results are as follows. First, correlation analyses revealed that game addiction was positively correlated with aggression and private self-consciousness. Private self-consciousness was also positively correlated with aggression. Considering two factors of private self-consciousness, game addiction showed a significant positive correlation only with self-reflectiveness factor. Although two factors of private self-consciousness showed positive correlations with game addiction, regression analyses revealed that self-reflectiveness was the significant predictor of aggression. Second, the structural equation analyses showed that private self-consciousness, especially self-reflectiveness was found to partially mediate the influence of game addiction on aggression. Finally, limitations of this study and suggestions for further study were discussed.

This study aims to identify the effects of factors on aggression in adolescents, focusing on the individual, parent, friend factors and SNS usage. In particular, this study is to provide a basis for easing aggression in adolescence by considering the emotional relationship of parents and friends. This study analyzed frequency, t-test, one-way batch distribution analysis(ANOVA), and multi-linear regression, using the data from the 7th year of the Korean Children and Youth Panel Survey. As a result, adolescents who frequently use SNS are more aggressive than adolescents who use less. Among the parental factors, the more abuse and excessive interference were found to be more aggressive, and the higher the coach, the lower the aggressiveness. Furthermore, among the friend factors, it has been shown that the higher the alienation, the more aggressive adolescents are. In order to reduce aggression among adolescents, it is necessary to prepare an integrated program considering the emotional relationship of parents and friends, who are the most influential neighbors, rather than simply restricting the use of SNS.
