The purpose of this study was to examine the differences between aggressive and nonaggressive boys with the use of a social information processing approach. The subjects were 80 3rd & 6th grade boys selected from a public elementary school in Seoul. The subjects were interviewed individually. Following the presentation of each story, five questions were asked. A 2 x 2 Analysis of Variance was performed for each of the 5 dependent measures. Results showed (1) Aggressive boys were more likely to attribute a hostile intention to the behavior of peer. (2) Aggressive boys predicted their own response as more hostile and aggressive. (3) The 6th graders generated more alternative solutions than the 3rd graders. (4) Non significant results are not reported in the abstract. (5) Aggressive boys were likely to choose an ineffective solution.

This study explored the effects of emotional intelligence and sense of humor in institutionalized and at-home children on their aggressive behavior by using a path model. The participants in this study were 62 institutionalized children and 98 children reared at home, residing in an undisclosed city. The institutionalized children had a lower level of emotional intelligence and sense of humor than children at home. Also, the institutionalized children had a higher level of aggressive behavior than at-home children. Effects of emotional intelligence and sense of humor on the aggressive behavior were significantly different between institutionalized and at-home children.

This paper presents the potential of in-vehicle data recorder system for monitoring aggressive driving patterns and providing feedback to drivers on their on road behaviour. This system can detect 10 risky types of drivers' driving patterns such as aggressive lane change, sudden brakes and turns with acceleration etc. Vehicle dynamics simulation and vehicle road test have been performed in order to develop driving pattern recognition algorithms. Recorder systems are installed to 50 buses in a single company. Drivers' driving behaviour are monitored for 1 month. The drivers' risky driving data collected by the system are analyzed. Aggressive lane change in 50km/h below is a cause in overwhelming majority of risky driving pattern.

This case study was designed to test the effect of eclectic play therapy with parent's counseling and education programs for aggressive 2 years old boy. It was found that the boy had some important problems about emotion control ability, social problem-solving skill, and basic daily living practices adding to aggressive behavior. After the treatment of 10 sessions which taken once in a week, he showed much improved ability about emotion control, social problem-solving skill and basic daily living practices, and didn't show any more aggressive behavior without proper reason.

This study examined effects on children's emotional expressiveness and regulation strategies or maternal attitudes and emotional expressiveness. Participants were 180 children(88 girls) age 3-5, their mothers, and 20 teachers. Results showed boys used more aggressive and girls used more positive coping strategies. Younger children used more aggressive and non-expressive strategies. When mothers had more Permissive and Accepting attitudes, children used more positive coping strategies. When mothers had more Restrictive or Controlling attitudes, children used more aggressive strategies. When mothers expressed positive emotions, children used fewer aggressive and venting strategies. When mothers expressed negative emotions, children used more aggressive and fewer positive coping and non-expressive strategies. Negative maternal emotional expressiveness was an especially influential factor on children's emotional regulation strategies.

The purpose of this study was to assess the clinical outcomes of active periodontal therapy (APT) and supportive periodontal therapy (SPT) through loss of teeth in the Korean patients with aggressive periodontitis. The number of missing and residual teeth, probing pocket depth were examined in 33 patients diagnosed with aggressive periodontitis at the baseline and who had participated in APT and SPT for 3 years or more. A 20 and 3 teeth were lost during the APT and SPT, respectively. The mean tooth loss rate of 0.13 per patient and year. There was no significant statistical difference in clinical improvement between the smoker and non-smoker groups. Within the limitation of this study, APT combined with supportive therapy could decrease the risk of tooth loss in patients suffering from aggressive periodontitis.

The purpose of this study was to examine the effects of mothers' parenting behavior, preschool children's language ability and emotion regulation on peer competence and aggressive behavior. The subjects were 100 preschool children (49 girls and 51 boys; mean age, 70.30 months), their mothers and teachers, recruited from five daycare centers located in Gyeonggi-do area. Each child's language ability was assessed individually with the standardized measure, the Preschool Receptive-Expressive Language Scale and their teachers reported on the children's peer competence and aggressive behavior. Their mothers also reported on parenting behavior and their child's emotion regulation by questionnaire. The collected data was analyzed by correlation analysis and hierarchical regression. The main results of this study were as follows. First, preschool children's peer competence was positively related to maternal warmth and children's language ability. Their aggressive behavior was positively related to harsh maternal parenting but negatively related to emotion regulation. Second, hierarchical regression analyses revealed that children's language ability and maternal warmth predicted peer competence. Third, children's gender, emotion regulation, and harsh maternal parenting predicted aggressive behavior. These findings could provide basic information for programs and services to promote peer competence in preschool children.

This study explored the consistency of bullying, victimization and aggressive victimization, the relationships between bullying, victimization and aggressive victimization and overt/relational aggression, and the relationships between bullying groups and overt/relational aggression with gender. The subjects were 4th grade children and 2 years later they were contacted again. Instruments were the Bully-Behavior Scale, the Peer-Victimization Scale and the Peer Nomination Instrument. Bullying, victimization and aggressive victimization were decreased while there were consistencies in overt and relational aggression from 4th to 6th grade. In the correlation analysis, male victims at Time 1 were negatively related to overt and relational aggression at both Time 1 and Time 2. Female bullies were positively related to relational aggression at both Time 1 and Time 2. In the cross-sectional relations of overt aggression with bullying groups, there was a gender difference. In the relational aggression with bullying groups, only bullying groups had a significant difference. In the longitudinal relations of overt aggression with bullying groups, only gender had a significant difference. Males appeared to be more overtly aggressive than females. In the relational aggression, bullying groups, gender, and the interaction between bullying groups and gender had significant differences. Female bullies were more likely to be relationally aggressive than other groups.

The purpose of this study was to examine the effects of the time spent on violent internet games and game overindulgence on aggressive behavior exhibited by elementary school-aged boys and to investigate the mediating effects of self-control on the relationship between children's game overindulgence and their aggressive behavior. The subjects of this study were 118 fourth to sixth grade boys from five elementary schools. The instruments used were the aggression subscale of the Korean-Youth Self Report (Oh, Ha, Lee, & Hong, 2001), a questionnaire of the time spent playing violent internet games developed by the authors, the Internet Game Addiction Scale for Children (Kim, Lee, Kim, Kim, & Kim, 2006) and the Self-Control Scale (Nam, 1999). The data were analyzed by means of a Structural Equation Model (SEM). The results were as follows. First, children's self-control mediated the relationship between game overindulgence and aggressive behavior. Second, the amount of time spent playing violent internet games had no effect on children's aggressive behavior.

Purpose: Few epidemiologic studies have investigated aggressive periodontitis in Koreans, but such studies of disease prevalence and other clinical characteristics would be invaluable in providing proper treatment. The aim of this study was to assess the prevalence of aggressive periodontitis and to measure the extent of associated periodontal breakdown. Methods: The study population consisted of 1,692 patients who visited the Department of Periodontology, Wonkwang Daejeon Dental Hospital from January to December, 2010. Clinical parameters (probing depth, gingival recession, periodontal attachment loss) were measured by a single examiner, and radiographic examination was performed at the baseline. Results: Twenty-eight (1.65%) patients showed clinical features of aggressive periodontitis, of which 27 patients exhibited the generalized form, and 1 exhibited the localized form. There was no significant difference between the percentage of male and female patients. The probing pocket depth of the maxillary first molar was deeper than that of the other teeth and gingival recession was also the most serious at the maxillary first molar. The periodontal attachment loss was the highest at the maxillary first molar. The average number of missing teeth was 1.29 per subject. Loss of the second molar was prominent. Conclusions: Within the limitations of this study, the periodontal breakdown evaluated by attachment loss was found to be most severe at the first molars of aggressive periodontitis patients. However, further large scale multicenter studies are necessary to access more precise data, including prevalence.
