Objectives : The aim of this study was to investigate the gender differences of direct aggression and relational aggression in Korean elementary and middle school students. Methods : Parents of 946 elementary school students(age $9.54{\pm}1.72$ years, 485 boys, 461 girls) completed the Child Behavior Checklist(CBCL). Six-hundred-and-three middle school students(age $13.98{\pm}0.93$ years, 301 boys, 302 girls) completed the Youth Self-Report(YSR). Independent t-test, chi-square test, and Fisher's exact test were used. Results : Boys had significantly higher direct aggression scores than girls in elementary school students(p<0.001). There was no significance gender difference of relational aggression in elementary school students(p=0.235). In middle school students, boys had significantly higher direct aggression than girls(p=0.017), and girls had significantly higher relational aggression compared to the boys(p<0.001). Conclusions : Our results suggest the presence of gender differences in manifestation of aggression subtypes in Korean elementary and middle school students. These gender differences should be taken into account in prevention and intervention approaches of aggression in children and adolescents.

Problematic behaviors have been among adolescent population in school and home. Problematic behavior manifested in childhood and adolescence is reported to be a good predictor for adult criminal behavior although no clear factor to cause was identified. Based on literature review on this subject, our hypotheses that delinquency and aggressive behaviors are associated with brain information processing and emotionality in adolescents was developed and this study aimed to test these hypotheses. 1,479 male and female middle school students were selected and given the Trait Meta-Mood Scale, Korea Youth Self Report-Child Behavior Check List and Brain Preference Indicator Test. The main results are as follows: 1) Subjects with problematic behavior compared to average students showed a significant difference in sub-variables of emotionality ant the characteristics of brain information processing. 2) Young adolescent's emotionality and brain information processing characteristics have effects on problematic behaviors. 3) However, the effect on aggression and delinquency was different by gender.

The unexpected increase of violent crimes in Korea urges people to look for more dynamic explanations of criminal behavior other than sociological eugenics such as a struggle between social classes or assimilation to deviant social environment. In this study, criminal behavior is treated as personal matter according to the tradition of psychological theories of crime rather than sociological phenomenon. Furthermore, aggression is supposed to be one of the most basic dispositional characteristics of violent acts. Therefore, this study explored the relationship between aggression measured by BPAQ and criminality evaluated based on seriousness of criminal offenses. On the other hand, the cross-validity of BPAQ was also investigated since prevalence and expressive forms of violence is known to vary across cultures and even within a society. The variance analyses and causal modeling presented that BPAQ had satisfactory level of cross-validity and dispositional aggression measured by BPAQ might have causal effect on criminality of Korean offenders. Additionally, a theoretical internal structure of BPAQ had been confirmed to be reasonable by confirmatory factor analyses.

Aggressive behavior triggered by the tendency to become angry is generating various social problems. To combat these various social issues, it is important to recognize the role that empathy plays in preventing those with trait-anger from becoming aggressive. More specifically, the hypothesis that empathic concern and perspective taking would mitigate the association between trait-anger and aggression was examined through this study. 329 college students participated in a survey containing questions related to trait-anger, aggression, empathic concern and perspective taking. The results showed that empathic concern moderated the association between trait-anger and aggression, whereas perspective taking did not. That is, those who are emotionally empathetic do not act aggressively easily even if their trait-anger is high; while those who are cognitively empathetic struggle to reduce the likelihood of their trait-anger leading to aggressive behavior. The result of this study indicates that emotional empathy was more useful than cognitive empathy in preventing those with trait-anger leading to aggressive behaviors. The implications, limitations and future directions of this study were also considered and presented as well.

The purpose of this paper is to analyze the behavior of North Korea's cyber attack against South Korea since 2009 based on major international security theories and suggest South Korea's policy option. For this purpose, this paper applied the behavioral domain and characteristics of 'cyber power' and 'coercion dynamics' model, which are attracting attention in international security studies. The types of cyber attacks from North Korea are classified into the following categories: power-based incarceration, leadership attacks and intrusions, military operations interference, and social anxiety and confusion. In terms of types and means of cyber power, North Korean GPS disturbance, the Ministry of Defense server hacking and EMP are hard power with high retaliation and threat and cyber money cashing and ransomware are analyzed by force in the act of persuasion and incentive in the point of robbing or asking for a large amount of money with software pawns. North Korea 's cyber attack has the character of escape from realistic sanctions based on the second nuclear test. It is important for South Korea to clearly recognize that the aggressive cyberpower of North Korea is changing in its methods and capabilities, and to ensure that North Korea's actions result in far greater losses than can be achieved. To do this, it is necessary to strengthen the cyber security and competence to simultaneously attack and defend through institutional supplement and new establishment such as cyber psychological warfare, EMP attack preparation, and enhancement of security expertise against hacking.

Objectives: The aim of this study was to establish the basic data for adolescents' mental health states in a community. Methods: 466 middle school and high school students were analyzed by visit-survey with an organized questionnaire from March to June 2008. K-YSR for measurement of mental health was used. Results: The score of total behavior (p<0.01), anxious/depressed (p<0.05), though problems (p<0.001), attention problems (p<0.001), aggressive behavior (p<0.01) and internalizing problems (p<0.05) in girls appeared significantly higher as compare to those the boys. Also, total competence (p<0.05) in high school students appeared significantly lower as compare to those middle school students. Withdrawn (p<0.01) in high school students appeared significantly higher as compare to those middle school students. The though problems (p<0.001) and aggressive behavior (p<0.05) in middle school students appeared significantly higher as compare to those high school students. The distribution of clinical group was school 93.8%, total competence 32.6%, attention problems 8.8%, total behavior problems 8.6%, anxious/depressed 7.7%, aggressive behavior 6.4% et. al. The social (p<0.05), anxious/depressed (p<0.05), attention problems (p<0.01), internalizing problems (p<0.05) and externalizing problems (p<0.05) in girls of clinical group were more frequent significantly as compared to those the boys of clinical group. Also, the social (p<0.01) in middle school students of clinical group was more frequent significantly as compared to those the high school students of clinical group. Conclusions: This study result will be significant in that it can provide basic data for the school mental health services.

The aim of this study is to explore the school adaptation and aggression of the children selected from 3 different SES communities and to investigate how parenting styles and children' school adaptation and aggression are different according to community-level socio-economic status. Subjects were 441 elementary school graders(229 boys and 212 girls, from the 4th graders to the 6th graders. Community SES was measured by the proportion of adult population holding a bachelor's degree or higher among the whole adults aged more than 30 and divided into 3 regions(rated high, middle and low in the metropolitan city). Data analysis was by F-test and multiple regression. The children from the high and middle SES community were more adaptive to school and less aggressive than those from the lower SES community. And the parents(or caregivers) from the high and middle SES community were more authoritative than those from other regions. These findings tell us that the children from the lower SES community are at risk and that some special programs to support children and their parents are needed.

Objective：Present study investigated the relationship between mothers' self-perception and perception of children's problems. Method：Subjects were 63 children, mothers, who visited child & adolescent psychiatric clinic. Their mothers completed Minnesota Mulpiphasic Personality Inventory(MMPI) & Korean Personality Inventory for Children(KPI-C). Correlation between validity scales of mothers' MMPI and validity scales of KPI-C was analysed, and then we divided subjects into two group(High & Low Group) according to the MMPI validity scales, and compared KPI-C's validity scales by student t-test. Result：There were significant positive correlation(r=.30) between K scale of MMPI and L scale of KPI-C, significant negative correlation(r=-.32) F scale of MMPI and L scale of KPI-C. The Means of T scores did show significant difference according to MMPI F, K scales in KPI-C L scale, to MMPI L scale in KPI-C F scale. Conclusion：These results indicated that defensive mothers tend to perceive her child's problems more defensively. However mothers who exaggerate their problem more severely, do not exaggerate their children's problem. Therefore, these result suggested that we should be careful not to underestimate children's problem whose mother elevated in K scale of MMPI.

Introduction：Test anxiety is a pervasive problem among high school students in Korea. While anxiety in test situations may actually facilitate the performance of some students, more often it is disruptive and leads to performance decrements. Over the past years, many child psychiatrists have become concerned with understanding the nature of test anxiety, but it is not clearly understood yet. In order to understand the nature of test anxiety, the relationship between test anxiety and depression, state anxiety, trait anxiety, temperament and family environment were examined. Methods：The Test Anxiety Inventory, Chidlren's Depression Inventory, State-Trait Anxiety Inventory, Temperamnet and Family Environment Scale Scale were administered to 576 high school students in Seoul. The relationships between test anxiety and other measures were tested using Pearson correlation coefficients and to test the causal relationship among the variables, regression analysis was performed. Results：The correlation coefficients between test anxiety and depression, state anxiety, trait anxiety, temperament and family environment scale were 0.42(p<0.01), 0.34(p<0.05), 0.38(p<0.05), 0.36(p<0.05) and -0.23(p<0.01), respectively. Regression analysis showed that only state and trait anxiety had direct causal relationship with test anxiety. Depression, temperament and family environment were indirecly related with test anxiety. Conclusions：This study indicates that the level of state and trait anxiety are directly related with test anxiety, and other variables such as temperament, family environment and depression are indirectly related with test anxiety. Thus, in order to develop the effective methods for treatment, these psychopathological characteristics should be kept in mind and the most important factors are the levels of state and trait anxiety.
