Purpose: To describe the profile of chronic and aggressive periodontitis among Senegalese (West Africans) attending the Institute of Dentistry of Dakar. Methods: A retrospective study was conducted with an inclusion period running from 2001 to 2008. The sample included 413 chronic periodontitis and 151 aggressive periodontitis cases, among them 299 males and 265 females selected from 2,274 records. A Student's independent t-test or Pearson chi-squared test was used for data analysis. Results: The proportion of females with aggressive periodontitis was significantly higher than those with chronic periodontitis (64.9% vs. 40.4%, P<0.001). The aggressive periodontitis patients had an average age of $28.1{\pm}8.9$ years, and had lost less than 3 teeth. Less than a third of them reported using a toothbrush. Attachment loss was as high as 8 mm and severe lesions had spread to an average of 12 teeth with maximum alveolar bone loss up to 80%. The chronic periodontitis patients had an average age of $44.9{\pm}14.0$ and had lost on average less than 3 teeth. Nearly 75% used a toothbrush. Attachment loss was significantly higher and lesions were more extensive in the aggressive periodontitis. Chronic periodontitis is associated with risk factors such as smoking or diabetes mellitus in 12.8% versus 0.7% in aggressive periodontitis (P<0.001). Differences between the two groups for most clinical and radiographic parameters were statistically significant. Conclusions: The profile of aggressive periodontist is characterized by more severe lesions than chronic periodontitis, whereas tooth loss experience is similar in both forms.

Objectives: Although aggressive behavior in children and adolescents with attention-deficit/hyperactivity disorder (ADHD) has previously shown correlations with hyperactivity/impulsivity, few studies have examined its association with inattention or the effect of working memory on aggressive behavior. This study aimed to assess the relationship between inattention and aggressive behavior and the effect of working memory on the relationship between inattention and aggressive behavior in children and adolescents with ADHD. Methods: Thirty-one children and 26 adolescents with ADHD were retrospectively investigated. The subjects completed the Korean Wechsler Intelligence Scale for Children-Fourth Edition (K-WISC-IV), the Korean Child Behavior Checklist (K-CBCL), and the Korean Children's Depression Inventory (CDI). Results: Inattention was positively correlated with aggressive behavior in children and adolescents with ADHD and working memory showed an insignificant correlation. However, working memory had a significant moderating effect on aggressive behavior by interacting with inattention. The moderating effect of working memory manifested when the working memory index score on the K-WISC-IV was 73.5 points or higher, and it had a significant effect on aggressive behavior. Conclusion: This study shows that the severity of inattention and hyperactivity/impulsivity should be addressed to provide appropriate treatment to children and adolescents with ADHD who exhibit aggressive behavior.

This study investigated the relationship among children's sensation seeking, maternal childrearing behavior and children's problem behavior. The subjects were 470 5th and 6th grade elementary school students in Pusan, Korea. Zuckerman's questionnaire on sensation seeking(1994), Park, Young Yae's questionnaire on maternal childrearing behaviors(1995) and Kim Hye Ryun's questionnaire on children's maladjustment behavior(1993) were used. The results were as follows : (1) According to sex, there were significant differences in sensation seeking stores, the aggressive behavior scores and distracted behavior scores. The boys got higher scores than girls in sensation seeking scores, and also in aggressive behavior scores and distracted behavior scores. (2) There were significant positive correlations between sensation seeking scores and the aggressive behavior scores for both boys and girls. And there were significant positive correlations between sensation seeking scores and the distracted behavior scores for both boys and girls. (3) Both sensation seeking and maternal child rearing behavior predicted aggressive behavior and distracted behavior for both boys and girls. For boy's aggressive behavior, sensation seeking and maternal child rearing behavior explained 8%, 8%, respectively. For boy's distracted behavior, sensation seeking explained 5%. And for girl's aggressive behavior, sensation seeking and maternal child rearing behavior explained 27%, 9%, respectively. For girl's distracted behavior, sensation seeking and maternal child rearing behavior explained 28%, 7%, respectively. The sensation seeking variable was the important predictor influencing on children's aggressive behavior and distracted behavior. Implications of this study were discussed in terms of sensation seeking and socialization.

Purpose: This study was conducted to identify predictors related to aggressive behavior of patients with mental illness admitted to a closed psychiatric ward. Methods: This study adopted a retrospective design which analyzed the hospital medical records of 363 patients with mental illness admitted to the psychiatric closed ward of a university hospital in Seoul, Korea. The collected data were analyzed using SPSS IBM 20.0 and STATA 12.0 SE. ZIP (Zero-Inflated Poisson) and count data analysis were used for the factor influencing the occurrence and frequency of aggressive behavior. Results: The results of ZIP model showed that the factors influencing non-probability of aggressive behavior were anxiety, non-adherence, and frustration. In addition, the factors influencing frequency of aggressive behavior were bipolar disorder and personality disorder trait. Conclusion: We found that bipolar disorder, frustration, and non-adherence are more likely to increase the likelihood of aggressive behavior in patients with mental illness. In particular, patients diagnosed with bipolar disorder were 1.95 times more likely to engage in repetitive aggressive behavior compared to those without a diagnose. However, since the results were different form previous studies, further studies on the traits of anxiety and personality disorders are needed.

Nowadays, aggressive driving is a common driving behavior and it is raised as a dangerous factor for both drivers and passengers. However, it is hard to find studies on aggressive driving in Korea, and even the definition of aggressive behavior is not clearly explained. In this study, the term "aggressive behavior" is defined based on previous studies, and the significance of several psycho-social factors which affect aggressive driving were verified with the 'habit' factor from the Theory of Planned Behavior (TPB). In the pilot study, domestic drivers reported that aggressive behaviors included speeding, traffic light signal violation, and improper passing (cutting drivers off when passing). In this study, controlling the demographic characteristics of these three aggressive behaviors, the authors explored the relationship of the behaviors with TPB factors such as the habit factor. Consequently, in the case of drivers' intentions for speeding and traffic light signal violations, subjective norm, perceived behavioral controllability, and habit were significant factors. In the case of intentions for improper passing, only perceived behavioral controllability and habit were significant. In speeding behavior and traffic light signal violations, only habit was significant besides intention; however, in improper passing, both perceived behavioral controllability and habit were significant besides intention. The authors also tested an alternative model including TPB and habit factors for three types of aggressive driving. Finally, there are several implications for a possible intervention program for aggressive driving, though there are some limitations of the study.

Aggressive fibromatosis is a rare soft tissue tumor with locally invasive and infiltrative characteristics. The mechanism of this invasive nature was not reported until now. Mutations or reduction of PTEN, tumor suppressor gene, in cancer tissues, have been found to be associated with invasiveness and metastatic properties of cancer cells. To know the pattern of expression of PTEN in aggressive fibromatosis, we analysed the expression of PTEN with immunohistochemical stain and immunoblotting. PTEN was homogeneously expressed in the normal musculoaponeurotic tissues, but absent or very faint in tissues of patients with aggressive fibromatosis as evidenced by western blot analysis and immunohistochemical examinations. Although the meaning of decreased PTEN expression in aggressive fibromatosis is not certain, it might be involved in the growth of the aggressive fibromatosis, and associated with phenotype of aggressive fibromatosis.

Objectives: This study was to develop a measurement scale that explains aggressive regulation behavior of middle school student, based on Ajzen's Theory of Planned Behavior (TPB) and verify its validity and reliability. Methods: The basic items were modified by selecting 41 items of middle school student aggressive behavior measurement scale. Through the content validity test, 63 first preliminary question items and 42 second preliminary question items were developed. The participants were 286 middle school students. The collected data were analyzed using content validity, correlation coefficient, exploratory factor analysis, confirmatory factor analysis, reliability and Cronbach α. Results: In this study, it was proved that the most important variable showing aggressive regulation behavior was aggressive regulation intention. This study was composed of 4 factors for direct measurement(attitude toward the behavior, subjective norm, perceived behavioral control, behavior intention) and 5 factors for indirect measurement(behavioral beliefs, outcome evaluation, normative beliefs, motivation to comply, control beliefs). The total variance was 65.4% and 67.6%, respectively, and the reliability was .90, .82. Finally, 42 questions were developed. Conclusion: We found the questionnaire used in this study was valid and reliable as a measure scale to explain the aggressive regulation behavior of middle school student based on TPB. Therefore, it is concluded that the aggressive regulation behavior scale could be a useful scale for the measurement of the aggressive regulation behavior of middle school student.

The primary purpose of this study was to examine the influence of mothers' emotion expressiveness and children's attributional biases on children's aggressive behavior, focusing on gender differences. The data were collected from a total of 86 children; 46 6-year-old boys and 40 6-year-old girls in kindergartens, and their mothers in Seoul. The emotion expressiveness of the mothers were measured by a self-reported Korean version of SEFQ(Self Expressivness Family Questionnaire). Attributional biases of the children were evaluated by using Dodge and Frame's Story-Based Interview Scale. Children's aggressive behavior were measured by teachers using a children's Aggressive Behavior Scale developed by Crick(1995). T-test, correlation analysis, and multiple regression were used to analyze the collected data. The results showed that the relational attributional biases of children positively influenced overt/relational aggressive behaviors. The emotion expressiveness of mothers and the aggressive behavior of children, however, were not significant. Regarding gender differences in children, the negative emotion expressiveness of mothers predicted the girl's relational aggressive behavior negatively. Implications and limitations of this study were discussed.

As violent video game is used based on active interaction and involvement of users, it is widely thought that it may have more effect on individual violence and aggressive action than existing violent videos. This study aimed to examine the effect of user experiences in the violent video game such as hostility, anger, arousal, enjoyment and identification on users' aggressive action. For this purpose, the first person FPS shooting game that consists of violent contents was employed to carry out playtest for 80 subjects with 40 male and 40 female university students. As a result, it was found that the user's arousal level, state anger, enjoyment and identification experience by the use of violent video game had an effect on aggressive action. Among factors that have aggressive action in the used of violent video game, besides emotion and arousal, the level of identification with a game character was found to be important effect factor. Hostility factor that was assumed to have effect on aggressive action was not significant, but enjoyment of game was proved to have effect on aggressive action of users.

In this study, mothers of 205 4- to 5-year-old preschoolers responded to aggression episodes of Werner et al. (2006); preschoolers' teachers responded to the Preschool Social Behavior Scale (Crick et al., 1997). Results showed, (1) boys exhibited more overt and relational aggression. (2) In overt aggression episodes, mothers used encouragement to boys and rule violation responses to girls; in relational aggression episodes, mothers used encouragement and power assertion responses to girls. (3) Mothers' power assertion about overt aggression related negatively with preschoolers' overt aggressive behaviors; mothers' discussion about relational aggression related positively with preschoolers' overt aggressive behaviors. Implications of these findings for the mothers' responses by aggression types were discussed in order in better understand preschooler's aggressive behaviors.
