  • This study examines teachers' implementation of strategies to modify the aggressive behavior of students with intellectual disabilities in Saudi Arabia, to determine the obstacles to their real-world execution. In addition, it presents potential approaches to overcome the obstacles to implementing strategies with this group of students. The research employed a qualitative design using semi-structured interviews as a data collection tool and applied a thematic analysis. The study population comprised 35 teachers of students with intellectual disabilities and the study sample numbered six teachers. The interviews were conducted via different methods: three by phone, two face-to face, and one using the Zoom platform. The results revealed inadequate understanding among teachers of intellectual disability and behaviour modification strategies, and this affected their capacity to develop plans that were compatible with the needs of students with intellectual disability. The findings also identified multiple obstacles that impede teachers' implementation of strategies to modify aggressive behaviour among students with intellectual disabilities; the most important being the lack of input from a psychological specialist when developing programs to modify aggressive behaviour. In general, it is apparent that programs for modifying aggressive behaviour are neither structured nor complementary, due to the scarcity of administrators with sufficient knowledge and familiarity with the characteristics and personalities of students with intellectual disabilities. This study presents several recommendations, the most important of which is that teachers of students with intellectual disability should develop themselves through training courses to enable them to deal with these students and create treatment plans that include strategies and clear steps to modify the aggressive behaviour of students with intellectual disabilities. To support teachers, it is also necessary to remove the obstacles facing education centres by providing financial support to create an environment in which they can access the required devices and equipment in their classes.

  • The purpose of this study was (1) to investigate the difference of temperament, self-regulation, and problem behavior according to children's gender and age, (2) to investigate the relationship among three variables by use of canonical correlation analysis. The subjects were 210 children ages from 3 to 5 in five day-care center in Incheon city. The SPSS WIN 12.0 Program was used to analyze the collected data. The statistical methods were Frequency, Percentage, Cronbach's ${\alpha}$, Two-way ANOVA, Correlation analysis, and Canonical Correlation analysis. The major results of this research are summarized as follows: (1) Children's temperament were significantly different by their gender and age. The boys got higher score than girls in adaptability, activity, and total temperament. Girls got higher score than boys in reactivity. The age 3 got higher score than the age 5 in activity and the ages 3, 4 got higher than the age 5 in total temperament. (2) Children's self-regulation were significantly different by their age. The children who were older got higher scores in self-regulation ability. (3) Children's problems behavior were significantly different by their gender and age. The boys got higher score than girls in anxiety behavior, aggressive behavior, hyperactive/distractive behavior, and total problem behavior. And the ages 3, 4 got higher score than the age 5 in anxiety behavior and hyperactive/distractive behavior. The age 4 got higher score the ages 3, 5 in aggressive behavior and the age 3 got higher score the ages 4, 5 in total problem behavior.

  • 공격운전은 주변차량 운전자를 위협하며 주행하기 때문에 교통사고 발생 개연성이 높다. 따라서 공격운전의 법제도 마련, 검지, 관리방안 등 대책이 필요하다. 본 연구의 목적은 공격운전의 주행행태가 교통류에 미치는 영향을 분석하였다. Multi-agent 주행 시뮬레이션과 교통류 시뮬레이션 VISSIM을 이용하여 공격운전의 거동을 구현하였다. 교통류 시뮬레이션과 상충분석을 이용하여 공격운전이 교통운영효율성 및 교통안전성 측면에서 교통류에 미치는 영향을 분석하였다. 분석 시나리오는 다양한 교통상황과 공격운전차량 비율을 고려하여 설정하였다. 상충분석 결과 일반적으로 공격운전 주행행태는 교통안전성을 감소시키는 것으로 나타났다. 교통운영효율성 분석결과 흥미로운 점은 서비스 수준 A, B, C 경우 공격운전차량 비율이 증가할수록 평균주행속도가 증가하였다. 이와 반대로 서비스 수준 D와 E인 경우 공격운전차량 비율이 증가할수록 평균주행속도가 감소하였다. 본 연구 결과는 공격운전을 줄이기 위한 교통안전정책 마련 시 기초자료로서 효과적으로 활용될 수 있을 것으로 기대된다.

  • This study investigated characteristics of children's coping behaviors in the context of perceived controllability of stress in hassles with parent(s), friend-alienation, friend-conflict, and in learning situations. The subjects were 489 sixth grade children selected from seven elementary schools in Seoul. Statistical analysis was by ANOVA, Scheffe' test, and MANOVA. Major findings were that (1) Active, passive, aggressive, and avoidant coping differed by perceived controllability of stress in all 4 stress situations. The children who perceived a higher level of controllability were more active, and less passive, aggressive, and avoidant in coping with each hassle. (2) Perceived controllability was higher in learning related than in friend-conflict situations. Active, passive, and social support seeking coping behavior was higher in learning related stress situations than in friend-conflict situations. Avoidant coping behavior was lower in learning related than in friend-conflict situations.

  • Data were collected by peer nomination and sociometric nomination when children were in 4th grade and again two years later, Concurrent results of peer nominations were that prosocial children were more accepted while overtly/relationally aggressive children were more rejected by peers. Peer acceptance of males at Time 1 affected peer acceptance at Time 2. Peer rejection of females at Time 2 wasn't affected by overt aggression at Time 1. Cross-sectional results of social status were that rejected and controversial children showed higher levels of overt aggression than any other group. Popular children were most prosocial; rejected children were least prosocial. In the prospective view, aggressive males remained more rejected than any other group. Rejected children remained least prosocial.

  • Two types of aggressive behavior were produced by selective breeding in ICR mimce. NC900 line mice exhibited high level of species-typical, isolation-induced aggression, conversely, NC100 line mice exhibited little aggression. The present study tested the hypothesis that these differences involved brain monoamine systems. Comparisons of microdissected samples from various brain regions showed that NC100 line mice had significantly lower concentrations of dopamine. DOPAC and HVA in the nucleus accumbens (NAB) and caudate nucleus (NCU) than NC900 line. Homogenate binding studies demonstrated that NC100 mice had significantly increased density of $D_1$ dopamine receptor, but not $D_2$ dopamine receptor in the caudate nucleus. These results support the hypothesis that central dopamine pathways play an important role in modulating the genetically selected differences in aggressive behavior, and of which intensity differs from TEX>$D_1$\;and\;$D_2$ dopamine receptors.

  • This paper presents a simulation tool for developing and evaluating automated driving systems' lane change algorithm in urban congested traffic. The behavior of surrounding vehicles was modeled based on driver driving data measured in urban congested traffic. Surrounding vehicles are divided into aggressive vehicles and non-aggressive vehicles. The degree of aggressiveness is determined according to the lateral position to initiate interaction with the vehicle in the next lane. In addition, the desired velocity and desired time gap of each vehicle are all randomly assigned. The simulation was conducted by reflecting the cognitive limitations and control performance of the autonomous vehicle. It was possible to confirm the change in the lane change performance according to the variation of the lane change decision algorithm.
