The main propose of this study was 1 examine the relations of parenting behaviors perceived by children to children's aggression and Unsocial behaviors with a sample of 301 6th-graders(161 boys and 140 girls) and their teachers(N=10). The children answered questionnaires regarding parenting behaviors such as physical punishment psychological control, md responsiveness. Children's aggression and unsocial behaviors were rated by their teachers. Boys showed higher overt aggression than girls. Children were more aggressive when they perceived that their parents used more physical punishment and psychological control and they were less responsive. Children showed more prosocial behaviors when they perceived that their parents used less physical punishment' and psychological control and they were more responsive. The more aggressive the children were, the less prosocial they were.

The purpose of this study was to explore relationships between preschooler's aggression and social skills, maternal management strategies of peer relations and parenting behaviors and preschoolers' internet-game addictive inclination. Participants included seventy-seven (77) 5 to 6-year-old preschoolers (44 boys, 33 girls) and their mothers. The Aggressive Behavior Scale (Lee & Choi, 2001), the Social Skill Rating Scale (Suh, 2004), the Maternal Parenting Behaviors Scale (Rhu & Lee, 2007) and the Parental Involvement Checklist (Park, 2001) were used in this study. The Internet Game Addiction Scale (Korea Agency for Digital Opportunity and Promotion, 2006) was used to identify higher and lower addictive level of internet-game inclination. Collected data were analyzed by descriptive statistics and t-test. Major findings revealed that preschooler's social skills, maternal management strategies of peer relations and parenting behaviors showed a predictable correlation to preschooler's internet-game addictive inclination.

최근 많은 보안 공격 도구들은 커널 레벨에서 동작하도록 설계 되고 있다. 악의적인 행동이 시스템 모니터링 프로그램과 같은 권한 레벨에서 이루어지기 때문에 공격 도구들은 공격 대상으로부터 자신의 존재를 숨기고 활동할 수 있다. 이러한 커널 레벨 악성코드들에 대한 대처 방법으로 가상화 기술을 이용하는 더 높은 권한 레벨을 가진 가상머신모니터(VMM)에서의 시스템 모니터링 방법이 소개 되었다. 그러나 많은 가상화 기반 모니터링 도구들이 주로 페이지 폴트 예외를 이용하여 시스템 콜 호출을 감시하기 때문에 신뢰성이 떨어지고 확장 페이지 테이블 (EPT) 과 같은 최신 하드웨어 가상화 기술 지원을 받지 못한다. 이에 본 논문에서는 일반 보호 예외를 이용하는 새로운 시스템 콜 인터셉트 기법을 제안함으로써 기존 기법의 기술적 한계를 극복하고 신뢰도 높은 모니터링 기법을 제공하고자 한다. 또 해당 기법의 구체적 구현 방법을 서술하고 구현 결과를 실험함으로서 제안 기법을 검증한다.

Objectives : Alzheimer's disease(AD) is characterized by progressive decline of cognitive function and also by various behavioral psychological symptoms of dementia(BPSD) which causes distress to their caregivers. The purpose of this study was to investigate association between each AD patients' behavioral psychological symptoms and their caregivers' burden. Methods : Participants were 80 AD patients and their caregivers. We used Korean neuropsychiatric inventory (K-NPI) to assess the symptoms of patients and Korean version of Zarit Burden Interview(ZBI) to evaluate caregivers' burden. Results : The results showed ZBI score, which is the index for caregivers' burden, had a statistically significant positive correlation with the frequency of delusion, hallucination, agitation/aggression, depression, anxiety, disinhibition and irritability, the severity of hallucination, agitation/aggression, anxiety, disinhibition, aberrant motor, and sleep, and the global score(frequency${\times}$severity) for delusion, hallucination, agitation/aggression, depression, anxiety, disinhibition, aberrant motor, and sleep. There were significant correlations between each scale for cognitive function(i.e. MMSE-KC, CDR, GDS) and ZBI scale. Correlations between each scale for activity of daily living(i.e. Barthel -ADL, K-ADL) and ZBI scale were also significant. Conclusions : There were a significant correlation between BPSD and caregiver burden. Caregiver burden was also correlated with cognitive function and activity of daily living. Early detection and preventive treatment of these symptoms in BPSD might make improvement of caregivers' quality of life as well as AD patients'.

The purpose of this study was to examine validity of the Korean-Child Behavior Checklist: K-CBCL) as measures for emotional and behavioral problems for use with children with autism spectrum disorders. In present study, the factor of the K-CBCL was investigated, using data of 248 children with autism spectrum disorders, with 11.17 mean ages. The two factor model of Internalizing problems (Withdrawn, Somatic Complaints, Anxious/Depressed) and Externalizing problems (Delinquent Behavior, Aggressive Behavior) was investigated by the confirmatory factor analysis. The two factor model of K-CBCL was adequate for children with autism spectrum disorders. The inter-item consistency for the sub-factor of K-CBCL demonstrated on adequate reliability of the measure. Although the inter-item consistency of Withdraw, Social problems, Delinquent Behavior was not acceptable, the inter-item consistency of Internalizing, Externalizing and total problems were good. This results supported validity and reliability and suggested that K-CBCL is used to assess for emotional and behavioral problems in children with autism spectrum disorders.

Objectives：Considerable data indicate that diminished serotonergic activity is related to aggressive behavior. In order to understand the biological etiology in conduct disorder, we studied the relationships of plasma serotonin and 5-HIAA levels in conduct disorders to measures of aggression, violation of rules and oppositional defiant behavior. Methods：Subjects were selected from inpatients and outpatients department of the Division of Child and Adolescent Psychiatry of Seoul National University Hospital. 41 conduct disorders(18 childhoodonset type, 23 adolescent-onset type) and 23 normal controls were included in this study. For the assessment of aggression, rule violation and oppositional behavior, parents completed the rating scale for conduct disorder and oppositional behavior based on the DSM-IV diagnostic criteria. Plasma serotonin and 5-HIAA levels were determined by HPLC with electrochemical detection. Results：1) Plasma 5-HT and 5-HIAA levels were not significantly different among childhood-onset conduct disorder, adolescent-onset conduct disorder and normal control subjects. 2) No significant correlations were found between plasma 5-HT levels and aggression or rule violation. 3) Plasma 5-HT levels showed significant positive correlations with oppositional behavior both in childhood-onset conduct disorder and adolescent-onset conduct disorder. 4) Age-related changes were not found in plasma 5-HT and 5-HIAA levles. Conclusion：Our findings do not support the hypothesis that dysregulation of serotonergic function may be associated with aggresson. Instead, our data suggest that serotonergic function is more closely related with oppositional behavior than aggression.

This study examined the relations among toddlers' temperament, maternal parenting, and toddlers' social withdrawal and aggression. One hundred and two mothers of two-year-old children (49 boys and 53 girls) completed questionnaires and Q-sort. Data were analyzed by correlation analyses and regression analyses. First, toddlers' pleasure was negatively related to social withdrawal, while social fearfulness was positively related to social withdrawal. Also, toddlers' activity level and anger proneness were positively related to aggression. Second, the encouragement of independence in maternal parenting was negatively linked to toddlers' social withdrawal, and maternal rejection was positively linked to toddlers' aggression. Third, toddlers' pleasure and interest/persistence were positively associated with mothers' encouragement of independence, and toddlers' activity level and anger proneness were positively associated with mothers' rejection. Finally, mothers' encouragement of independence acted as a mediator between toddlers' pleasure and social withdrawal. Also, toddlers' activity level and anger proneness influenced aggression through maternal rejection. These results indicate that toddlers' temperament and maternal parenting play crucial roles in the development of toddlers' maladaptive behaviors such as social withdrawal and aggression.
