This study aims to explain the effect of mother's child rearing behavior on aggression of young children and to verify the mediating effect of self-control between two variables. For the purpose, 1,524 children who fit this study among children aged 5 through 7th year of the Korean Children's Panel were selected. The data were analyzed by using the hierarchical regression method and the Sobel test. The main findings are as follows. First, the mother's warmth of rearing behavior was shown to decrease aggression of children, while mother's control of rearing behavior had no influence their aggression. Second, It was shown that the self-control of young children had a negative effect on their aggression. Third, self-control was shown to have a partial mediating effect in the relationship between the mother's warmth of rearing behavior and aggression of children. Accordingly, various programs to reduce the aggression of young children were suggested and an alternative plan was proposed to be applied to child care sites.

In the present study, we studied the change patterns of adolescents' overt aggression during the middle school 2nd to the high school 1st grades and the effects of ecological factors on the change. For the research goals, we applied multi-level models to the Korean Youth Panel data. Results showed that adolescents' overt aggression decreased significantly during the period. Gender(males recoded as 1) and self-control had negative effects on the initial status(middle school 2nd grade) while the number of delinquency peers had a positive effect. On the other hand, gender and self-control showed positive effects on the change rate. The major strengths of the research are the study of various ecological factors and the longitudinal design. Few studies of adolescents' aggression have incorporated these methodological and substantive characteristics.

원전에 대한 사이버 공격이 날로 늘어나고 있는 현 상황에서 원전업계가 스스로 이를 방어해 낼 수 있는 방법은 무엇인가? 한 조직이 혼자서 자기의 사이버 영역에 대한 공격에 대비할 수는 없다. 그런 식으로는 언제나 사이버 공격보다 한 발 늦을 뿐이다. 이 싸움은 일종의 군비 경쟁 같은 것이기 때문에 서로 간의 협력을 통해 우리를 위협하는 사이버 공격자들보다 유리한 고지를 선점하고 있어야 하는 것이다.

현대의 인터넷 환경에서는 다양한 서비스 채널을 통해 정보의 유통이 활발히 이루어지고 있다. 이러한 환경에서는 기존의 정보보호의 한계를 이용하는. 특히 사회 공학적 공격 기법을 활용하는 DoI(Denial of Information. 정보거부) 공격과 같은 사이버공격으로 인해 중요한 보안 문제를 유발 할 수 있다. DoI 공격은 악의적인 공격자가 유용한 정보임을 가장하여 의도적으로 악성정보를 포함하여 유통함으로서, 네트워크 사용자가 원하는 정보를 찾아서 자기 것으로 만드는데 필요한 다양한 가용 자원을 소모하도록 하는 공격이다. 본고에서는 현재 만연하는 DoI 공격의 형태 및 상황을 알아보고. DoI 공격을 대응하기 위한 프레임워크는 어떤 것이 있는지 살펴본다.

The purpose of this study is to examine the relationship between rejection sensitivity and reactive aggression among college students, as well as to determine the mediating effects of self-concept clarity and hostile attribution bias on the relationship between rejection sensitivity and reactive aggression. A self-report questionnaire was conducted online for the purpose of gathering data from university students aged 18 years and older. A total of 250 participants were included in the analysis. SPSS 27.0 was used for data analysis to check the basic statistics of the variables, frequency analysis, reliability analysis, and correlation analysis. In addition, the model fit was checked using Amos 21.0, and the bootstrapping method verified the significance of the indirect effect. The results of this study are as follows. The results of this study are as follows. First, rejection sensitivity positively affects reactive aggression through self-concept clarity. Second, rejection sensitivity increases the hostile attribution bias, leading to an increase in reactive aggression. Third, rejection sensitivity positively influences reactive aggression in an indirect way by sequentially affecting self-concept clarity and hostile attribution bias. These findings have implications as they identify psychological factors that affect reactive aggression in college students. This suggests the importance of utilizing psychological interventions to address reactive aggression associated with social problems, such as crime, and provides a foundation for both treatment and prevention. Finally, implications for further research and limitations of this study are suggested.

Change of paradigm of network attack technique was begun by fast extension of the latest Internet and new attack form is appearing. But, Most intrusion detection systems detect informed attack type because is doing based on misuse detection, and active correspondence is difficult in new attack. Therefore, to heighten detection rate for new attack pattern, visibilitys to apply human immunity mechanism are appearing. In this paper, we create self-file from normal behavior profile about network packet and embody self recognition algorithm to use self-nonself discrimination in the human immune system to detect anomaly behavior. Sense change because monitors self-file creating anomaly detector based on Negative Selection Algorithm that is self recognition algorithm's one and detects anomaly behavior. And we achieve simulation to use DARPA Network Dataset and verify effectiveness of algorithm through the anomaly detection rate.

The purpose of this study is to verify the causal relationship between depression and aggressiveness among adolescents. The 4-year longitudinal data collected from 2,670 4th grade elementary school students by the Korean Youth Panel study was used in this study. From the analysis result using the Autoregressive Cross-Lagged Model, the depression and aggressiveness in adolescents were continued from elementary school 4th grade to middle school 7th grade in significant stability. In addition, the previous aggressiveness turned out to have significant positive effect on the later period depression. Similarly, the previous depression had significant effect on the later aggressiveness, but the direction was negative. This means that the adolescents's depression increases as their aggressiveness increases, but as the depression increases, the later aggressiveness of the adolescents decreases. There were no differences between girls and boys within the relationship of these two variables. Finally, the implication derived from the results, the limitation of this study, and suggestion for following studies were presented.

This study investigated the effects of social presence as means of self-awareness and interpersonal-awareness on the cyber-aggressive behavior. The cyber-aggressive behavior (flaming and direct aggression use of character) should be differ from existence of social presence and type of social presence of internet users. To test hypothesis, an experiment was executed a field study on cyberspace, an on-line game, "fortress 2 blue forever". I made a chat-room in the game site to conduct an experiment to 107 person who entered the chat-room and blinded ignorance of this situation made by researchers. As the subjects enter the chat-room, he chats with 3 researchers who were waiting before he gets in. The social presence was operated with 3 phases by the contents of the chat (①control group; nothing, ②experimental group 1; reaction about other people ③experimental group 2; reaction about other people + self-exposure by an exchange information of their home region). The studies show that, subjects of the control group behaved more aggressively than other subjects of the experimental groups(both flaming and direct aggression use of character). Meantime, I compared experimental group 1 with experimental group 2 to investigate difference between the type of social presence. As the result, subjects of the experimental group 1 behaved more aggressively than experimental group 2 (only flaming, there's no difference in direct aggression use of character).

최근 인터넷을 대상으로 한 네트워크 공격의 공격 경향은 분산 환경에서 다수 공격자의 대규모 분산 서비스 거부 공격(DoS)의 출현 및 해외 해커들의 국내 전산망을 우회 루트로 활용한 사례의 증가 등 고도화된 불법 행위가 점차 벙죄의 강력한 수단으로 이용되는 추세에 있다. 본 논문은 기존 네트워크 노드기반의 침입탐지시스템에서 효율성과 사용자 편의성을 보완하기 위하여 자기 복제가 가능한 이동 에이전트를 적용하여 호스트 간 자율적인 이동을 통해 관리자에게 네트워크 모니터링을 제공하고 침입을 탐지하는 침입탐지시스템을 제안하였다.

In this paper, we study the security of key recovery enhanced key exchange protocol. We present a subliminal channel of self-escrowed Diffie-Hellman key exchange protocol proposed by P. Paillier and M. Yung in ICISC\`99, and also we present a method to prevent such a subliminal channel. In addition, we review and analyze the weakness of the modified key recovery enhanced key exchange Protocol proposed by C. Kim and p. Lee in PKC 2001.
