The purpose of this study was to explore anger and its expression, psychoticism, addiction, and coping styles of victims, especially aggressive victims of dating violence, and to provide valuable information for prevention of dating violence and rehabilitation of victims. The participants were 477 female college students who had the experience of heterosexual dating relationships, whose ages ranged from 17 to 29 (M=20.59, SD=1.44). The psychological tests used in this research included the following: Straus' Conflict Tactics Scale, Spielberger's State-Trait Anger Expression Inventory, Eysenck Personalty Inventory, and multidimensional Coping Scale. Results revealed that victims only were more likely to receive violence as well as sexual harassments from their dating partners than aggressive victims of dating violence. Aggressive victims of dating violence showed higher level of trait anger and anger-out, and difficulty in control their anger than victim only and women who had not experienced dating violence. In addition, they also revealed symptoms of paychoticism and addiction. And aggressive victims of dating violence showed less active coping and more active forgetting and renunciation than victims only and women who had not experienced dating violence. Victims only of dating violence more like to criticize themselves and pursue religious coping than aggressive victims. Researcher discussed these results with previous studies.

최근 이슈가 되고 있는 직장내 괴롭힘은 가해자가 피해자에게 정신적, 신체적 건강에 악영향을 주는 대표적인 이직요인이 되고 있다. 직장내 괴롭힘을 발생시키는 폭력은 그 폭력의 강도가 다소 약한 상태의 공격적 행동을 피해자 에게 전달하지만 이를 지속적이며 비신처제적인 공격으로 인해 피해자의 입장에서는 결국 강한 폭력과 같다고 할 수 있다. 이에 본 연구는 이러한 직장내 괴롭힘을 직무소진이라 하고 직무만족과 직무이직에 어떠한 요인이 가장 크게 작용하는지를 알아보고자 한다.

The purpose of this study was to investigate characteristics of victims, especially aggressive victims of dating violence, and examine how they constructed the dating relationship and their commitments in dating relationships. The participants were 526 female college students who had the experience of heterosexual dating relationships, whose ages ranged from 18 to 37 (M=20.10, SD=2.70). The psychological tests used in this research included the following: Straus' Conflict Tactics Scale, Foo and Margolin's Justification of Violence Scale, Korean Version of Gender-Role Scale, and Lee and Han's Relationship Measures. Results revealed that aggressive victims of dating violence were more likely to receive mild violence as well as severe violence from their dating partners than victims only, while women who were victim only experienced sexual harassments more than aggressive victims from their dating partners. Aggressive victims of dating violence had experienced fathers' domestic violence more than women who had not experienced dating violence. Victims of dating violence showed less negative attitude toward dating violence than women who had not experienced dating violence. Victims of dating violence showed stronger commitments in their dating relationships than women who had not experienced dating violence. The results of this study may provide valuable information for professionals who help victims of dating violence.

요즘 인터넷을 통하여 많은 사이버 공격이 일어나고 있다. 이에 대응하기 위하여 우리는 네트워크 패킷을 저장할 수 있는 사이버 블랙박스 시스템을 개발하고 사이버 블랙박스 시스템에서 수집한 많은 네트워크 패킷을 분석할 수 있는 효율적인 공격 원인 분석 알고리즘을 제안한다. 공격원인 분석 알고리즘을 통하여 우리는 사이버 공격에 발생했을 때 공격의 유입점이 어디이고 어떤 경로를 통해서 공격이 이루어졌는지 알 수 있다. 그 뿐만 아니라 숨겨진 피해자 발견 알고리즘을 통하여 알려진 피해자뿐만 아니라 알려지지 않은 다른 피해자를 찾을 수 있다.

This study was to examine the effect of Displaced aggression and Justice sensitivity(victim sensitivity and penetrator sensitivity) on Cyberbullying tendency in 20s adult, and the moderating role of Justice sensitivity to identify psychological factors affecting a serious social problem, cyberbullying. The online survey was handed to 261 adults in their 20s for a month. First, Simple regression analysis shows that displaced aggression(F=62.55, p<.001) and victim sensitivity(F=29.61, p<.001) predict cyberbullying tendency. Second, hierarchical regression analysis by controlling the effects of sex, the perpetrator sensitivity has been shown to morderate the relationship between displaced aggression and cyberbullying tendencies(F=29.61, p<.001), and the effect of victim sensitivity has not been significant. In conclusion, that future studies need to consider the limitations of this study to ensure that the same results are shown in different age groups and also some approaches such as empathetic understanding could help to reduce cyberbullying.

The purpose of this study was to analyze responses as bystanders of middle school girls in a simulated cyberbullying situation. This study also aimed to examine effects of bullying, victimization, anger-out, and state-anger on responses from girls as bystanders. The participants were composed of 2nd or 3rd grade middle school girls(N=59). Responses were classified into 7 categories(using explicit language, attacking, pass, changing topic, comforting victims, others, and conformity). Of these, attackings were classified according to the target(bully, victim, both, and ambiguous object). It was again classified as 'attacking response' and 'helping response' and was scored and summed according to the strength of the response and used as a dependent variable. Collected data were analyzed by correlation analysis and multiple regression analysis. The results of this study are as follows: First, the most frequent response was 'the others'(41.69%) followed by 'using explicit language'(20.34%), 'passing'(13.56%), 'attacking bully'(8.81%), 'conformity'(8.64%), 'changing topic'(6.61%), and 'comforting victim'(0.34%). Second, responses of attacking victim were positively influenced by the previous bullying experiences and acting anger-out, and were negatively influenced by the previous victimization experience. State-anger has a positively influenced on responses of the attacking bully and the helping victim. None of the variables were significant influenced on responses of the attacking both and ambiguous object. These results will be useful data to help middle school girls as bystanders properly intervene in cyberbullying situation. Finally, the limitations of this study were discussed along with suggestions for further research.

한 호스트에게 과다한 트래픽을 보내는 서비스 거부 공격을 막기 위하여, 허용한도 이상의 트래픽을 차단할 필요가 있다. 이 때 가능한 한 트래픽의 근거지에서 가까운 곳의 라우터에서 그 차단을 실행해줄수록 이상적으로 차단할 수 있으므로, 공격자의 네트워크 상의 위치를 파악하는 일이 중요하다. 본 연구에서는 피해자의 요청 및 공격의 파악에 따라, 피해자와 공격자사이에 있는 공격경로 상의 라우터들이 서로 협조하여 공격자를 적발할 수 있는 프로토콜을 제안한다. 설계된 프로토콜은 시뮬레이션을 통하여 성능을 평가하였으며, 그 결과 설계된 프로토콜은 적은 시간 내에 공격자의 위치를 찾는 효과를 가져왔다.

In this paper, we analyze the feasibility of the IP spoofing attack exploiting null security algorithms in 5G networks based on 3GPP standard specifications. According to 3GPP standard specifications, the initial Registration Request message is not protected by encryption and integrity. The IP spoofing attack exploits the vulnerability that allows a malicious gNB (next generation Node B) to modify the contents of the initial Registration Request message of a victim UE (User Equipment) before forwarding it to AMF (Access and Mobility Management Function). If the attack succeeds, the victim UE is disconnected from the 5G network and a malicious UE gets Internet services, while the 5G operator will charge the victim UE. In this paper, we analyze the feasibility of the IP spoofing attack by analyzing whether each signaling message composing the attack conforms to the 3GPP Rel-17 standard specifications. As a result of the analysis, it is determined that the IP spoofing attack is not feasible in the 5G system implemented according to the 3GPP Rel-17 standard specifications.

This study was conducted to identify the relationship between child abuse and school violence and whether aggression and depression have any mediating effects on this relationship. This study analyzed the responses of 1,937 eighth grade students. The main results of this study were as follows. First, child abuse was positively correlated with school violence aggression and school violence victimization. Second, aggression and depression mediated the effect of child abuse on aggression and victimization, respectively. Third, aggression mediated the effect of child abuse on victimization. Fourth, although there was a reciprocal causal relationship between aggression and victimization, school violence victims who were abused by their parents were less likely to be the perpetrators of violence themselves. These findings have implications regarding the use of counseling intervention to prevent violence in schools.

최근까지 랜섬웨어 공격은 끊임없이 발생하고 있으며 공격자의 암호기술에 대한 이해가 향상되면서 다양한 암호 알고리즘을 사용하여 피해자의 중요한 데이터를 암호화하고 있다. 블록 암호만을 사용하던 초창기 랜섬웨어와 달리 최근 몇 년 전부터 스트림 암호를 사용하여 데이터를 암호화하는 랜섬웨어가 계속해서 발견되고 있다. 따라서, 본 논문에서는 스트림 암호 기반 랜섬웨어의 동작과정, 암호화 과정을 기술적으로 분석하여 어떠한 형태로 악성행위를 수행하는 지 알아보고자 한다
