  • Objectives : The aim of this study was to investigate the gender differences of direct aggression and relational aggression in Korean elementary and middle school students. Methods : Parents of 946 elementary school students(age $9.54{\pm}1.72$ years, 485 boys, 461 girls) completed the Child Behavior Checklist(CBCL). Six-hundred-and-three middle school students(age $13.98{\pm}0.93$ years, 301 boys, 302 girls) completed the Youth Self-Report(YSR). Independent t-test, chi-square test, and Fisher's exact test were used. Results : Boys had significantly higher direct aggression scores than girls in elementary school students(p<0.001). There was no significance gender difference of relational aggression in elementary school students(p=0.235). In middle school students, boys had significantly higher direct aggression than girls(p=0.017), and girls had significantly higher relational aggression compared to the boys(p<0.001). Conclusions : Our results suggest the presence of gender differences in manifestation of aggression subtypes in Korean elementary and middle school students. These gender differences should be taken into account in prevention and intervention approaches of aggression in children and adolescents.

  • The purpose of this study is to measure the effect of musical activities on children's aggressiveness using percussion playing through case studies and to present the therapeutic programs. Musical activities using percussion playing were organized for three aggressive children. Twenty-one small group sessions were conducted over seven weeks with 30 minutes given each session. Fourth-grade children involved in using Aggressiveness Measuring Tool for Teachers-revised by Gwak Geum-Joo(1992) was selected for case studies. Children's impulsiveness was also tested through self-test measuring tool for impulsiveness-revision of 16 questions used by Cho Hae Yeon (2001) and Lee Joo Shik (2003). As quantitative method, comparative analysis was made between the pre and post test results using measuring tools for aggressiveness and impulsiveness of children as well as between aggressive behaviors occurring in the initial stage of the first three sessions and in the latter stage of the last three sessions. Qualitative method was used at the same time to examine the effect of percussion playing on children. After the musical activities, child A showed reduced Aggressive Measuring Tool scores from 19 to 18, with child B from 23 to 19 and child C from 21 to 18. The results show that occurrence of aggressive behaviors were lowered in the post test. Impulsiveness Measuring Tool scores in the post test were decreased as well in all three children. During the music therapy programs, it was also observed that the frequency of the target behaviors in all three children has reduced more in the latter stage than the initial stage of music therapy. The qualitative findings indicate that the children experienced releasing stress through self-expression after percussion playing. These findings indicate therapeutic effectiveness of music therapy using on percussion playing in reducing aggressiveness of children as well as the effectiveness of percussion as a therapeutic intervention for aggressive children. These results can be adapted and reapplied by teachers in primary schools to approach children with behavior problems, and can present a useful therapeutic approach to therapists practicing in clinical environments.

  • The purpose of the study was to investigate the relationship among children's perception of parenting style, their social anxiety, aggression, and school adjustment. A total of 267 children(male 117, female 150) and 10 homeroom teachers participated. Each child completed questionnaires on perception of parenting style, and social anxiety. Children's aggression and school adjustment was measured by their homeroom teachers' reports. The results of the structural equation model showed that children's perception of parenting style high in rejection and control significantly influenced aggression as well as school adjustment, but didn't influence social anxiety. Both parenting style high in rejection and control and aggression had significant effect on school adjustment. Our results showed that parenting style high in rejection and control directly influenced school adjustment, and mediated by their aggression.

  • The study is to find out the influence of mother's and father's conflict resolution styles(aggressive and compromising) on adolescents' use of swear words. This study also investigates whether aggression has a mediated effect in terms of the relationship between mother's and father's conflict resolution styles and their children's use of swear words. To this end, self-report type of questionnaire was conducted to 570 students who attend at 6 different middle schools located in Gyeongnam Province. To the exclusion of incomplete and insincere answers, 477 were selected as the raw data of the research. The summarization of the results is as follows: First, the aggressive type of conflict resolution style with mothers has positive correlation with the students' use of swear words. When the conflict resolution style with mothers gets aggressive, their children's use of swear word increases accordingly. Second, it is confirmed that aggression has a mediated effect when it comes to teenagers' use of swear words triggered by mother's aggressive conflict resolution styles and father's aggressive conflict resolution styles. Therefore, if the conflict between children and parents is not appropriately resolved, the children's aggression accumulates and thereby children's use of swear words increases.

  • 최근의 네트워크 공격의 주류는 DoS (denial-of-service)와 DDoS (distributed DoS) 공격이다. 이러한 공격들은 공격자가 침입 대상 시스템의 자원을 완전히 소모시켜서 시스템이 정상적인 서비스를 할 수 없도록 하는 것이다. 각 시스템의 관리자들은 이러한 침입이나 공격을 막기 위한 방편 중에 하나로 IDS(Intrusion detection system)를 사용하고 있다. 그러나 IDS의 높은 false-positive(정상적인 사용을 공격으로 잘못 판단하는 경우)의 발생빈도는 심각한 문제점 중의 하나는 이다. 이런 false-positive의 발생빈도를 줄이고자 본 논문에서는 한번의 판단만으로 연결(connection)을 차단시키지 않고, trust라는 개념을 도입하여 trust의 값에 따라서 사용자에게 차등 서비스를 제공하는 기법을 제안한다. 즉, trust를 이용하는 기법은 각 사용자를 한번에 공격자인지 일반 사용자인지 결정하지 않고, 한 번 더 검사하여 false-positive의 발생빈도를 감소시키는 기법이다.

  • 무선 ad-hoc 네트워크는 이동 노드만으로 구성된 자율적이고 수평적인 네트워크이다. 무선 ad-hoc 네트워크에서의 라우팅 프로토콜은 table driven 방식과 on-demand 방식으로 나뉘는데, 이 중 라우팅 메시지의 오버헤드가 비교적 적은 on-demand 방식이 주로 사용되고 있다. 이 프로토콜은 경로를 찾기 위해서 경로 요청 메시지를 브로드캐스팅 하는데, 경로 요청 메시지는 네트워크 전체로 확산되기 때문에 이를 이용한 공격이 가능하다 공격자는 연속적으로 경로 요청 메시지를 보냄으로써 패킷 충돌과 네트워크 큐오버플로우 등의 장애를 일으켜 정상적인 메시지나 데이터의 전송을 방해할 수 있다. 본 논문에서는 기존의 라우팅 프로토콜에 별도의 인증 절차 없이 경로 요청 패킷의 확산을 이용한 공격을 막는 방법을 제안하고자 한다. 각각의 노드는 경로 요청 메시지의 시작 주소와 수신 시간을 경로 요청 테이블을 이용해 관리함으로써 정상적인 경로 요청 패킷과 공격자의 경로 요청 패킷을 구분한다. 수신된 경로 요청 패킷이 공격자의 패킷이라고 판단된 경우, 공격자의 패킷을 이웃 노드에 전달하지 않음으로써 전체 네트워크에 가해지는 공격을 막을 수 있다.

  • 현대관계는 가상세계의 인간관계를 바탕으로 이루어진다. 사람과 사람과의 커뮤니케이션은 가상세계의 만남과 연결로 이루어지며, 비접촉적이고 비물질적인 관계의 발전으로 나아가고 있다. 현대인들은 나이에 상관없이 가상의 세계에서 자신을 홍보하고, 치장하며, 새로운 인간관계의 생산에 관여한다. 이들은 인간관계를 경계하며 그들을 이해하려 하지 않는 사람과의 교제보다는 그들을 이해하고, 같이 할 수 있는 사람들과의 관계를 선호한다. 즉, 그들은 직접적인 관계를 부담스러워하고, 가상적인 관계를 선호하며, 자신의 부재, 자신의 익명성을 무기화한다. 본 논문은 이런 비물질적인 관계의 공격성을 실제상황에서 보이는 영상이나 물질적인 오브제로 가시화하는 방법을 연구하고자 한다. 그 방법으로 초음파센서를 사용하여, 실제적인 거리에 따라 영상이나 오브제가 변화하는 방법으로, 웹에서의 공격성을 가시화하고자 하였다.

  • 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.

  • Although the cryptographic algorithms in IC chip such as smart card are secure against mathematical analysis attack, they are susceptible to side channel attacks in real implementation. In this paper, we analyze the security of smart card using a developed experimental tool which can perform power analysis attacks and fault insertion attacks. As a result, raw smart card implemented SEED and ARIA without any countermeasure is vulnerable against differential power analysis(DPA) attack. However, in fault attack about voltage and clock on RSA with CRT, the card is secure due to its physical countermeasures.
