Recently, the number of cases of child abuse has been increasing and, consequently, the social interest in this issue is increasing. The purpose of this study is to examine the relationship between child abuse, rejection sensitivity and emotional regulation and to identify the mediating effects of rejection sensitivity in the relationship between child abuse and emotional regulation. For this purpose, a survey on child abuse, rejection sensitivity and emotional regulation was administered to 217 elementary school students in the fourth, fifth and sixth grades, who had been reported as victims of child abuse or managed as suspected child abuse victims in the Seoul, Gyeonggi, Gangwon, Chungcheong, and Gyeongsang regions. The data was analyzed using structural equation modelling and bootstrapping. The findings showed that child abuse was significantly negatively correlated with emotional regulation, but positively correlated with rejection sensitivity. Emotional regulation was significantly negatively correlated with rejection sensitivity. Second, the structural equation analysis also revealed that rejection sensitivity fully mediated the relationship between child abuse and emotional regulation. This means that child abuse has an indirect effect on emotional regulation through rejection sensitivity. Therefore, when counseling abused children with emotional regulation problems, it is important for the counselors to include interventions designed to lower their rejection sensitivity.

The purpose of this study was to investigate the mediating effects of rejection sensitivity in pathological narcissism and dating violence, and to verify whether there is a gender difference in each variable, further examining the gender difference in the mediating pathways. The participants of this study were 381 men and women in 20s living across the country, and online self-report surveys was conducted regarding their experiences of pathological narcissism, rejection sensitivity, and four types of dating violence. As a result of verifying gender differences, it was found that women had a higher vulnerability to narcissism, rejection sensitivity and committed more psychological violence, sexual violence, and controlling behavior than men. As a result of the mediation analysis, it was found that rejection sensitivity partial mediated the effect of pathological narcissism on psychological violence and control behavior, but it showed a complete mediation effect on sexual violence. And there was no mediating effect of rejection sensitivity between pathological narcissism and physical violence. As a result of measuring the moderating effect of gender in this mediating pathways, the moderated mediating effect of gender was verified in the effect of naricissistic grandiosity and narcissistic vulnerability on control behavior through rejection sensitivity. These results show that pathological narcissism promotes psychological and sexual violence in both men and women, and rejection sensitivity acts as a mediator in this process. In addition, the effect of pathological narcissism on the control behaviors through rejection sensitivity was significantly higher in women than in men, indicating that there are gender differences in the mediated pathways. Finally, the implications and limitations of this study and suggestions for follow-up studies were discussed.

This study aimed to examine the effects of rejection sensitivity on depression and anxiety, and the moderating effects of school violence victimization experiences on the relationships between rejection sensitivity and both anxiety and depression. Based on the results, we suggested a method of screening soldiers at high risk of depression and anxiety and interventions for their psychological adaptation. The data about anxiety, depression, rejection sensitivity, and school violence victimization experiences was collected from 126 airmen in S city, South Korea. To test the moderation effects, multiple regression analyses were conducted in which the rejection sensitivity, anxiety, school violence victimization experiences and their interaction terms were hierarchically entered. The moderation of school violence victimization experiences was found in the relationship between rejection sensitivity and school violence victimization experiences. The specific interaction patterns in each of these significant interaction effects were examined. Finally, the importance of school violence victimization experiences as a high-risk factor in army life and the clinical implication of these findings were discussed.

Most legal systems provides the aggrieved buyer with a right to put an end to the contract. Unlike Civil Law systems, the right is rather complicated and uncertain in Common Law systems because they do not sharply distinguish between a refusal which amounts merely to a defence in the nature of the exceptio non adimpleti contractus, and one which is intended to abrogate the aggrieved party's obligations completely and to seek restitution of what he has already performed. That is, they do not draw any sharp distinction between the right of rejection or revocation and the right to put an end to the contract. This explains why the right to put an end to the contract under Civil Law systems are often compared with the right of rejection or revocation under Common Law systems in most academic papers. Having said that, this article describes and analyzes in detail the relevant UCC rules to the buyer's right of rejection and revocation, particularly the rules on the requirements for the right of rejection or revocation. This is for the purpose of providing legal advice to our sellers residing either in U.S.A. or in Korea who plan to enter into U.S.A markets and take academics' interest in the buyer's right which is deemed to be unique compared to the Civil Law systems. In addition, the study attempts to compare the rules as to the right of rejection and revocation under the UCC with those of English law which are stipulated mainly in the Sale of Goods Act (1979) in a statutory form. This may help one better to understand the rules of the UCC which are mostly originated with English law and to find in what way the rules of the UCC depart from those of English law.

In this paper, a UWB antenna using a SIR(Step Impedance Resonator) that eliminate signal interference at 5 GHz WLAN as the first rejection band and adjust the second rejection band is proposed. Unlike the unit impedance resonator, the second harmonic of SIR is decided according to step impedance. Therefore, To adjust the second rejection band, SIR is applied to UWB antenna. Also, the equivalent circuit of the antenna at first rejection band is presented and the equivalent modeling values of the SIR and the coupling value is obtained. The proposed antenna is satisfied to cover full UWB band with return losses less than -10 dB and has band rejection characteristic in 5 GHz WLAN band. The radiation patterns show +y directivity characteristics in H-plane and the group delay variations are within 1.0 ns.

Rejection characteristics of perchlorate ($ClO_4^-$) were examined for commercially available reverse osmosis (RO) and nanofiltration (NF) membranes. A bench-scale dead-end stirred-cell filtration system was employed to determine the toxic ion rejection and the membrane flux. Model water solutions were used to prepare $ClO_4^-$ solutions (approximately, $1,000{\mu}g/L$) in the presence of background salts (NaCl, $Na_2SO_4$, and $CaCl_2$) at various pH values (3.5, 7, and 9.5) and solution ionic strengths (0.001, 0.01, and 0.01 M NaCl) in the presence of natural organic matter (NOM). Rejection by the membranes increased with increasing solution pH owing to increasingly negative membrane charge. In addition, the rejection of the target ion by the membranes increased with increasing solution ionic strength. The rejection of $ClO_4^-$ was consistently higher for the RO membrane than for the NF membrane and $ClO_4^-$ rejection followed the order $CaCl_2$ < NaCl < $Na_2SO_4$ at conditions of constant pH and ionic strength for both the RO and NF membranes. The possible influence of NOM on $ClO_4^-$ rejection by the membranes was also explored.

The purpose of this study is to identify the mediated effects of social support in relation to college students' emotional control ability and rejection sensibility, and to provide basic data to intervene in students with high resistance sensibility. To this end, a survey of 449 university students was conducted and the hypothesis of this study was verified using a structural equation model. The analysis results are as follows. First, the relationship between emotional control ability, rejection sensibility and social support perceived by university students through correlation analysis showed significant correlation between emotional control ability, social support and rejection sensitivity. Second, in the structural model of social support in relation to emotional control ability and rejection sensibility, it was confirmed that social support played a role between emotional control ability and rejection sensibility. Based on the results of this study, some suggestions for the application and follow - up studies were discussed.
