In this study, causes and consequences of bullying were explored, focusing on victim personality and appearance factors. The research model included the relationships among bullying, important causes of bullying (aggression, cleanliness, and obesity of victims) and consequences of bullying (self-esteem and depression) and was tested through survey data from 594 (194 male and 404 female) middle school students. Data were analyzed using descriptive statistics, confirmatory factor analysis, and path analysis with SPSS and AMOS. In the results of the model tests, victims who are more aggressive, less clean, and more overweight are more likely to be bullied. In addition, adolescents bullied by others tend to have lower self-esteem and more depression. Furthermore, the model comparison was assessed by gender and a difference between the two gender models was found. In the check of critical ratio for difference, it was concluded that the cleanliness of the victim is a more important cause of bullying for male adolescents than for female adolescents. It is meaningful to confirm the effects of the victim's appearance factors on bullying in the literature focusing on personality issues of victims. Educators and counselors may refer to the findings in developing counseling guidelines and manuals to prevent bullying in school.

The purpose of this paper is to propose a detection algorithm and a tracking algorithm based on silent time using MB-OFDM UWB(Multi-Band Orthogonal Frequency Division Multiplexing Ultra Wide Band) receiver in order to satisfy DAA(Detect And Avoid) regulation of Korea to permit UWB in 3.1~4.8 GHz. In DAA regulation of Korea, if UWB device receives a signal more than -80 dBm/MHz from the victim system during UWB operation, the UWB system should avoid the collision within 2 sec. In this paper, we proposed the detection algorithm to detect the victim signal received by －80 dBm/MHz for the avoidance process that changes the operating UWB frequency to other UWB frequency and the subcarrier tracking algorithm to follow up the subcarrier positions of the victim signal for the tonenulling avoidance process that decreases the TX power of subcarriers occupied by the victim signal by -70 dBm/MHz. The performance of the detection algorithm and the tracking algorithm suggested in this paper is verified in simulation results considering various conditions.

This study aims to investigate the effects of adolescent's academic stress and their experience of school bulling victim on suicidal ideation, and the meditating effect of self-esteem among variables by utilizing the path analysis. Quantitative survey research was conducted with 1735 students attending primary, middle and high school to identify the following the key results. First, adolescent's academic stress directly influenced their suicidal ideation and its' effect was indirectly mediated by the subjects's self-esteem. Second, the relationship between the experience of school bullying victim and suicidal ideation was partly mediated by self-esteem. In other words, the severer academic stress in youth and the experience of bullying victim were, the higher suicidal ideation were; however, the adolescent's high self-esteem played a mediating role in lowering their suicidal ideation by increasing the ability of overcoming difficulties and risks.

Protection of personal information has significant meaning in current information age. Information of crime victim is one of top in value in that divulgence of the information to perpetrators may threat safety of the victim or cause psychological demage as $2^{nd}$ harm if disclosed to public. Legal system protects the information with scattered statutes including Criminal Procedure Act. Existing studies have been limited to discussion of the single statute without integrated approach. Bearing necessity of the approach in mind, as issues of protection system this research proffers too broad subject of eligible inspection of case document, inactive practice of identity management cards and omission of personal information, and inappropriate punishment on the disclosure or divulgence. After reviewing systems of foreign jurisdictions to get useful implications, this paper suggests several measures with two separate aspect of legal provisions and protection practice.

This study aims to investigate the convergence over effects of adolescent's maladaptive perfectionism and their experience of school bulling victim on suicidal ideation, and the meditating effect of parents-children communication among variables by utilizing the path analysis. Quantitative survey research was conducted with 1,395 students attending primary, middle and high school to identify the following the key results. First, adolescent's maladaptive perfectionism influenced positively their suicidal ideation but bullying victim not influenced their suicidal ideation. Second, adolescent's maladaptive perfectionism directly influenced suicidal ideation and its' effect was indirectly mediated by the subjects's parents-children communication. Third, the relationship between the experience of school bullying victim directly influenced suicidal ideation and its' effect was full mediated by the subjects's parents-children communication. In other words, Parents-children communication works to enhance their ability of dealing with difficulty which reduces suicidal ideation.

Radiation and radioactive materials serve man in many beneficial ways. Diagnostic X-ray, radiation therapy, and other nuclear medicine uses of radioactivity save thousands of lives each year. Industrial application of radiation, such as radiography, make many manufactured products more reliable and less expensive. Nuclear power plants are producing more electrical power each year and reducing our dependence on imported oil. However, radiation can and dose produce harmful effects particularly as the reault of a radiation accident in which a victim receives as the result of a radiation accident in which a victim receives a large dose. Fortunately such accidents are very rare and recently we need more electric power produced by nuclear power plants. Considering increase of use of radiation or radioactive materials, we have to establish the radiological emergency response system prepared for radiation accidents.

Purpose: To identify bullying tendencies among elementary, middle, and high school students. Method: A descriptive study was conducted with 911 participating students. Data were collected using three, self-administered questionnaires that had been modified by the investigator. The data were analyzed by the SPSS Win 10.0 program using descriptive statistics, ANOVA. Result: The level of bullying was significantly different among elementary school, middle school and high school students. Middle school students were higher than elementary and high school students. In subtypes of bullying, language type was higher than alienation and physical damage types in elementary, middle and high school students. The methods to resolve a bullying situation are for the victim to 'speak to parents' in elementary school students, but 'bear alone' in middle school and highschool students. The answer to the question 'how many of your friends have been the victim of bullying' was 3-8 friends'. The reason for being a bully victim was 'because they pretend to be a superior man'. Conclusion: Although much research has been conducted in this area, further study among elementary, middle and high school students needs to be conducted. Furthermore, a variety of programs for preventing bullying among elementary, middle and highschool students should be developed.

This study examined the effects of moral disengagement (cognitive restructuring and blaming the victim) and self-control on cyberbullying perpetration and investigated if self-control moderated the relationship between moral disengagement (cognitive restructuring and blaming the victim) and cyberbullying perpetration. Participants in the study consisted of 551 middle school students (273 boys and 278 girls) from five middle schools in Seoul and Gyeonggi-do. Cyberbullying perpetration, moral disengagement and self-control were measured using the Bullying/Victimization Questionnaire, the Mechanisms of Moral Disengagement Scale, and the Self-Control Scale for children and adolescents. Data were analyzed by means of descriptive statistics and a hierarchical regression analysis. The moderating effect of self-control was analyzed using procedures proposed by Baron and Kenny (1986). The results indicated that both levels of cognitive restructuring and blaming the victim increased cyberbullying perpetration whereas the level of self-control decreased cyberbullying perpetration. In addition, self-control moderated the effect of cognitive restructuring on cyberbullying perpetration. The influence of cognitive restructuring on cyberbullying perpetration was greater when the level of self-control was low, compared to when it was high.

Voice phishing (vishing) uses social engineering, based on people's trust in telephone services, to trick people into divulging financial data or transferring money to a scammer. In a vishing attack, a scammer often modifies the telephone number that appears on the victim's phone to mislead the victim into believing that the phone call is coming from a trusted source, since people typically judge a caller's legitimacy by the displayed phone number. We propose a system named iVisher for detecting a concealed incoming number (that is, caller ID) in Session Initiation Protocol-based Voice-over-Internet Protocol initiated phone calls. Our results demonstrate that iVisher is capable of detecting a concealed caller ID without significantly impacting upon the overall call setup time.
