This study examined the mediating effects of self-reassuring and self-attacking in the relationship between mental health and psychological well-being among college students. The study subjects were 230 (98 males and 132 females), and the collected data were analyzed using the SPSS PROCESS Macro based on regression analysis. The results of the study were as follows. First, there were significant relationship among mental health, psychological well-being, self-reassuring and self-attacking. Second, depression, obsessive compulsive disorder, interpersonal sensitivity and psychosis had a significant negative effect on psychological well-being. Third, self-reassuring and self-attacking had a partial mediating effect on the relationship between mental health and psychological well-being. The indirect effect of mental health on psychological well-being through self-reassuring was significantly higher than the indirect effect of psychological well-being through self-attacking. Based on the results of this study, we discussed the role of self-reassuring in the relationship between mental health and psychological well-being.

This study examined the mediation effects of covert narcissism on the relationship between game addiction and aggression. For this study, 578 middle school boys in Chungcheong areas were included in the analysis. The results are as follows. First, correlation analyses showed that game addiction was positively correlated with covert narcissism and aggression. In addition, covert narcissism showed positive correlation with aggression. Second, step-wise regression analyses were conducted to examine the relative size that sub-factors of game addiction and covert narcissism explained aggression. It could be known that three factors of game addiction(tolerance, disregard of everyday life, damage of control) and two factors of covert narcissism(exploitation/self-centeredness, oversensitivity/vulnerability) showed significant explanatory power for aggression. Third, the Structural Equation Model was designed in which factors of game addiction and covert narcissism with significant explanatory power for aggression were included. Covert narcissism was found to partially mediate the influence of the boys' game addiction on aggression. Finally implications of this study and directions for future research were discussed.

This study examined whether aggression mediates the effects of seven sub-types of narcissistic personality on psychopathy. It hypothesized that some of narcissistic personality could affect aggression that, in turn, contributes to psychopathy. The sample of this study consisted of 864 college students (451 males and 413 females). The participants completed an assessment battery consisting of Narcissistic Personality Inventory(NPI), Aggression Questionnaire(AQ), and Self-Reported Psychopathy Scale(SRPS). According to the results, narcissistic personality and aggression variables affected psychopathy, and aggression predicted students' psychopathy. The effects of students' narcissistic personality on psychopathy were partly mediated by aggression. The research findings partly supported the hypothesis, and were discussed on gender differences in relation among sub-types of narcissistic personality, aggression, and psychopathy. The implications and limitations of this study were suggested.

The purpose of this study was conducted to test mediating effects of self-efficacy in the relationship between aggressiveness and smartphone addiction in adolescents. A self-reprting survey was conducted on 665 adolescents. The research findings are as follows: First, there were significant correlations among aggressiveness, smartphone addiction, self-efficacy. Aggressiveness had positively correlations with smartphone addiction. Aggressiveness had a negative correlation with self-efficacy and smartphone addiction had negatively correlation with self-efficacy. Secondly, self-efficacy had a significant partial mediating effect between aggressiveness and smartphone addiction. Based on the results of this study, that the improvement of youth self-efficacy influence on the prevention and solution of smartphone addiction was discussed.

최근 인터넷의 폭발적인 확장에 따라서 웹 서버의 절대 개수가 증가하였으며 웹 바이러스에 의만 웹 서버의 공격도 빈번해졌다. 바이러스의 무제한 자기 증식이라는 특성에 따라 인터넷상의 공격 패킷의 증가로 인하여 네트워크가 마비되고, 특히 IIS가 DoS공격으로 인하여 많은 피해를 입었다. 이에 따라 웜 바이러스의 공격을 방어하기 위한 많은 방법이 제시되었는데, 본 논문에서는 윙 바이러스의 공격 패턴을 분석하여 웜 바이러스의 공격 패턴의 특성이 어떠한지를 연구하였다. 대부분의 웜 바이러스 공격이 IIS에는 유효하지만 유닉스 시스템에서는 무력한 점을 이용하여 UNIX 시스템에서 구동되는 Apache 웹 서버의 로그 정보를 사용하여 웜 바이러스의 공격 패턴을 분석하였다 분석 결과 웜 바이러스의 공격 패턴은 Hurst 상수 H에 의만 자기 유사성을 나타내는 것을 알 수 있었다.

This study examined the structural relationship among personal belief in a just world, presence of meaning in life, self-control, and aggression in college students. For this research, self-reported data from 427 college students were analyzed by gender, using structural equation modeling. Results indicated that personal belief in a just world predicted aggression regardless of gender. The mediating effect of self-control was non-significant among both women and men groups. The mediating effect of presence of meaning in life and self-control was significant among only women. It means that personal belief in a just world predicted presence of meaning in life and self-control, which consequently contributed to aggression among women. It is noteworthy that this study examined the concrete mechanism to reduce aggression by gender. Based on these findings, intervention strategies were discussed.

The purpose of this study was to search for empirical evidence between internalized shame with self-control, aggression, and addiction potential. Also examine the differences between clinical group and normal group. The data was collected from 100 AA participants and 380 Non-AA participants. For measuring each variable, internalizes shame scale(ISS), self-control rating scale(SCRS), Buss-Durkee Hostility inventory(BDH), addiction potential scale(APS) were used. The survey result was analyzed with Pearson Correlation, Partial correlation and t-test. The results shows: Frist, the internalized shame and the aggression, the addiction potential shows a positive correlation but the self-control shows negative correlation. Second, after control self-control, internalized shame positively correlate to addiction potential and aggression. Third, clinical group recorded a higher level in internalized shame, aggression and addiction potential than normal group; a lower level in self-control. Based on the finding, the implications of understandings, the interventions, the limitations of this study, and the suggestions were discussed.

데이터에 삽입되어 있는 워터마크를 제거하려는 공격기법이 점차 발전되면서 여러 가지 워터마킹 알고리즘이 등장하게 된다. 보통 워터마크를 제거하기 위해서는 워터마크 신호의 동기를 제거하는 동기-제거(De-Syncronization) 공격 방법을 이용한다. 이런 공격에 대처하기 위한 워터마킹 방법으로는 세 가지로 분류할 수 있는데, 공격에 영향을 받지 않는 영역(invariant domain)에 워터마크를 삽입하는 방법, 템플릿(template)을 이용한 방법, 자기 참조(self-reference)를 이용한 기법 등이 있다. 본 논문에서는 공간 영역에서의 자기 참조 워터마킹 방법을 소개하고, 이에 적합한 메시지를 삽입하고 검출하는 방법에 대해 제안한다. 삽입하려는 메시지와 Reed-solomon Code를 이용하여 만든 부가적인 정보를 QOS(Quasi-orthogonal sequences)방법과 DSSS를 이용하여 만든 다음 키 값을 이용하여 뒤섞으면 워터마킹 블록을 자기 참조 워터마킹 방법으로 영상에 삽입하게 된다. 그 결과 일반적 필터링 공격에는 95% 이상 검출됐고, JPEG 압축 파라미터 60에서도 97% 이상 검출되었다.

The purpose of this study is to investigate the mediating effects of aggression and self-esteem on the relationship between perceived parental attachment and self-control of soldiers. A convenience sample of 507 soldiers was employed, the following conclusions obtained. Parent attachment was positively correlated with self-control, aggression was negatively correlated with self-control and self-esteem was positively correlated with self-control. On the other hand, parental attachment had a indirect influence on self-control which was mediates through aggression and self-esteem as well as direct influence on self-control, and the mediating effect was much further aggression than self-esteem. Based on the above mentioned result, implication for counseling practice and future research are discussed.
