The relation of children's stress-coping styles to Risk of Internet Gaming Addiction(RIGA) was examined in 662 4th, 5th and 6th grade subjects. Results showed that active coping styles were negatively but aggressive and passive/avoidant coping styles were positively related to RIGA. In male students, coping styles of "active" and "passive/avoidant", "aggressive" influenced RIGA factors of "maladaptive behaviors" and "negative emotional experience". In female students, coping styles of seeking social support related positively to RIGA; coping styles of "active", "passive/avoidant", and "aggressive" influenced "maladaptive behaviors", "negative emotional experience", and coping styles of "active" and "passive/avoidant", "seeking social support" influenced "low academic attitude", RIGA factors, respectively. Coping styles of "active", "passive/avoidant", "aggressive", and "seeking-social-support" influenced "psychological absorption and fixation".

Aggression and aggressive behaviors, often explained as harmful social interaction with the intention of hurting or inflicting damage upon another, have been considered as an adaptive mechanism from the evolutionary psychological point of view. However, various studies on aggression and aggressive behaviors have been done with psychopathological approach as the extreme aggressive behaviors may harm themselves and others at the same time. Recently, researchers have attempted to explain aggression in terms of neurobiological substrates rather than based on traditional psychopathological and/or behavioral concept. In this regard, there have been findings of differences in neurotransmitters and their receptors, and genetic polymorphisms. In this review article, we provide a brief overview of the literature about seven most frequently reported neurotransmitters including neurohormones (serotonin, norepinephrine, dopamine, gamma-aminobutyric acid, nitric oxide, oxytocin and vasopressin) and an associated enzyme (monoamine oxidase A), which are known to be related with aggression and aggressive behaviors.

This study examined the effects of parenting behaviors, marital conflict and sibling relations on aggression with a sample of 301 6th graders (161 boys and 140 girls) living in P city. The subjects answered questionnaires regarding parenting behaviors, including sub-scales of physical punishment and psychological control, marital conflict, and sibling relations. Aggression was rated by peers. The results indicated that boys showed higher overt aggression than girls; children were aggressive when parents frequently used physical punishment and psychological control; the more children were exposed to marital conflict, the more aggressive they were, with particularly high correlations for girls; and the less positive and the more negative the sibling relations, the higher the aggression shown by children. Among the variables, parent's behaviors were the most highly correlated with aggression in both boys and girls.

오늘날 난폭운전은 도로에서 흔히 마주칠 수 있는 운전행동일 뿐만 아니라 운전자나 보행자와 같은 도로 이용자에게 매우 중요한 위험요인으로 대두되고 있다. 그러나 국내에서는 난폭운전과 관련된 연구를 거의 찾아볼 수가 없고 난폭운전에 대한 정의조차 마련되어 있지 않은 실정이다. 따라서 본 연구에서는 선행연구들을 바탕으로 난폭운전의 정의를 내리고 이러한 난폭운전에 영향을 미치는 것으로 보고된 여러 심리사회적 변인들의 유의성을 계획된 행동이론(Theory of Planned Behavior; Ajzen, 1985)과 Triandis(1977)가 제안한 '습관' 변인을 중심으로 검증하였다. 예비조사에서 국내운전자들을 대상으로 대표적인 난폭운전을 조사한 결과, 난폭운전은 과속운전, 신호위반 운전 및 끼어들기 운전 등의 순으로 보고되었다. 본 조사에서는 대표적인 난폭운전의 세 가지 유형 각각에 대해서 인구통계적 특성을 통제하고도 TPB 변인들과 습관변인들이 유의한지를 알아보았다. 연구결과, 과속운전 의도와 신호위반운전 의도의 경우 주관적 신념, 행동통제력 지각, 습관이 유의하게 나타났으며, 끼어들기운전 의도에서는 행동통제력 지각 및 습관만이 유의하게 나타났다. 과속운전 행동과 신호위반운전 행동은 의도 이외에 습관 변인만이 유의하였으나 끼어들기운전은 의도 이외에 행동통제력 지각 및 습관 변인 둘 다 유의하게 나타났다. 마지막으로, 세 가지 난폭운전 유형 각각에 대하여 계획된 행동이론 모형과 습관 변인을 추가한 대안모형을 검증하여 보았으며 이와 관련하여 연구의 제한점 및 난폭운전 교정프로그램에 대한 함의를 논의하였다.

We investigated the effects of maternal parenting behaviors, children's emotional regulation, and stress coping strategies on gender-specific children's behavioral problems. The participants were 191, $4^{th}$ and $5^{th}$ graders and their mothers from four elementary schools in Seoul and Kyung-gi province. Collected data were analyzed by descriptive statistics and hierarchical regressions. The major findings were summarized as follows: (1) Active coping strategies explained boys' aggressive behaviors, (2) mother's warm-encouragement parenting behaviors and active coping strategies explained boys' delinquent behaviors, (3) mother's warm-encouragement parenting behaviors explained boys' withdrawn behaviors, and (4) mother's mediation-supervision parenting behaviors and negative emotionality explained girls' aggressive behaviors. In conclusion, maternal parenting behaviors, children's emotional regulation and stress coping strategies have gender-specific influence on children's behavioral problems.

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.

난폭운전(aggressive driving)이란 '의도적으로 다른 운전자 또는 보행자에게 위함을 유발하거나 불쾌감을 주는 운전행위' (신용균, 강수철, 류준범, 권오정, 2006)로 교통사고로 이어질 가능성을 증가시킬 뿐만 아니라, 운전자 자신은 물론 주변의 다른 운전자와 동승자 및 보행자 모두의 생명을 위협하고, 막대한 사회 경제적 손실을 입히게 된다. 선행연구들에 따르면, 이러한 난폭운전은 주로 운전자의 성격이나 태도변인, 난폭운전 의도, 시간압박감, 도로교통 상황 등 심리사회적 변인들에 영향을 받는 것으로 보고되고 있다. 그러나 일부 연구들을 제외하고는 난폭운전과 관련된 대부분의 연구들에서, 주로 현장연구 또는 조사연구 방법 등을 사용하여 상관관계만을 제시할 뿐 실제 운전행동 측정치에 의한 인과관계를 규명하지 못하고 있는 실정이다. 따라서 본 연구에서는 개인차 변인으로 운전자의 난폭운전 의도 변인을 측정하였으며, 시간압박감과의 상호작용을 살펴보기 위하여 이를 실험적으로 조작하여 연구하였다. 연구결과, 난폭운전 의도나 시간압박감 수준에 따라 집단 간 차이가 유의하였을 뿐만 아니라 이러한 차이는 난폭운전 행동 유형에 따라 차이가 있었다. 특히 끼어들기 운전 행동에 있어서는 의도와 시간 압박감 수준의 상호작용 효과가 유의하였다. 마지막으로, 본 연구의 제한점 및 추후 연구와 관련하여 함의를 논의하였다.

This study investigated effects of parent-related variables on children's coping with stress. Subjects were 409 4th, 5th, and 6th grade children(213 boys and 196 girls) selected from three elementary schools in Seoul and Incheon. Data were analyzed by frequency, mean, and hierachical multiple regression. Major findings were that among the inter-parental conflicts perceived by the children, self-blame and triangulation affects children's coping behavior resulting in children's aggressive and passive/avoidant behaviors. The more children experience parent-related stress, the more children show aggressive and passive/avoidant coping behaviors. With more open-communication in parent-child relations, children's coping shows more active and social support seeking coping behaviors during stress situations.

Ketamine has long been used as an anesthetic agent. However, ketamine use is associated with numerous side effects, including flashbacks, amnesia, delirium, and aggressive or violent behavior. Ketamine has also been abused as a cocktail with ecstasy, cocaine, and methamphetamine. Several studies have investigated therapeutic applications of ketamine, demonstrating its antidepressant and anxiolytic effects in both humans and rodents. We recently reported that neonatal maternal separation causes enhanced anxiety- and aggressive-like behaviors in adolescent. In the present study, we evaluated how acute and chronic ketamine administration affected the behavioral consequences of neonatal maternal separation in adolescent mice. Litters were separated from dams for 4 hours per day for 19 days beginning after weaning. Upon reaching adolescence (post-natal day 35-49), mice were acutely (single injection) or chronically (7 daily injections) treated with a sub-anesthetic dose (15 mg/kg) of ketamine. At least 1 h after administration of ketamine, mice were subjected to open-field, elevated-plus maze, and resident-intruder tests. We found that acute ketamine treatment reduced locomotor activity. In contrast, chronic ketamine treatment decreased anxiety, as evidenced by increased time spent on open arms in the elevated-plus maze, and remarkably reduced the number and duration of attacks. In conclusion, the present study suggests that ketamine has potential for the treatment of anxiety and aggressive or violent behaviors.
