IL-18 has been found to have multiple effects upon various cells involved in tumor immunology. Here, we discuss opposite effects of IL-18 in tumor immunology. IL-18 has been shown that it has significant anti-tumor effects, which are mediated by T cells and NK cells, in a manner similar to IL-12. First, we investigated the evaluation of the effects of the systemic administration of IL-18 in combination with B7-1 (CD80) against murine B16 melanoma in vivo. (omitted)

The purpose of this study was to test the multiple mediating effects between attachment and life quality among university freshmen, regards on positive and negative affect, stress, social support and mental health as mediating factors. 200 freshmen were selected for the questionnaire study in a university in Busan. There were significant correlations among positive and negative affect, stress, social support, mental health and life quality with attachment. The maximum likelihood estimation revealed that attachment had no direct link with life quality. Attachment had indirect effects on life quality, mediated by positive affect and mental health. The results and limitations of this study were also discussed, from the perspective of attachment theory and previous studies.

This study explored mediating effects of the preschooler's emotional intelligence between maternal parenting behaviors and exclusion by peers. Subjects were 138 4- to 5-year-old preschoolers(92 boys, 46 girls) and their mothers. Exclusion by peers was measured by the Child Behavior Scale(Ladd & Profilet, 1996), maternal parenting behaviors were measured by the Parenting Questionnaire(Park, 1999), and preschooler's emotional intelligence was measured by the Emotional Intelligence Questionnaire(Lee, 1998). Data were analyzed by descriptive statistics and multiple regression analysis. Results showed that preschooler's emotional self-awareness mediated the effects of both maternal sensitive behaviors and maternal hostile/refusal behaviors on preschooler's exclusion by peers.

The purpose of this study was to examine the effects of sociotropy, as perceived by college students, and ambivalence over emotional expressiveness on their interpersonal problems. A total of 248 college students (127 males and 121 females) living in Seoul and Gyonggi responded to questionnaires, which included items related to sociotropy, ambivalence over emotional expressiveness, and interpersonal problem. First, college students' sociotropy was correlated with ambivalence over emotional expressiveness and interpersonal problems. It was suggested that people with high level of sociotropy experienced more emotional expressive conflict and interpersonal problems than people with low level of sociotropy. Second, male and female college students' ambivalence over emotional expressiveness partially mediated the relation between sociotropy and move toward other people, one of the interpersonal problem's subtypes. Male college students' ambivalence over emotional expressiveness has fully mediated the relation between sociotropy and move against other people, one of the interpersonal problem's subtypes. And female college students' ambivalence over emotional expressiveness has fully mediated the relation between sociotropy and move away from other people, one of the interpersonal problem's subtypes. According to gender difference, different interpersonal problems appeared. This study's results may provide some important suggestions for interpersonal problems in college students by increasing understanding of multiple dimensions according to their internal tendency and emotional expressiveness.

This study investigates the multi-dimensional structure of fashion store window creativity and examines its effects on consumer responses. Through an expert evaluation survey, this study proposes that fashion store window creativity involves originality, relevance, and artistry. Two experiments are conducted to test the proposed hypotheses. Consumers' emotional responses to the level of window creativity are collected using psychophysiological and self-report methods. Fashion store window creativity has positive effects on psychophysiological affective responses. When the three dimensions of creativity are specified as explanatory factors of emotional responses, relevance and artistry show positive effects on arousal and pleasure, whereas originality has a negative effect on pleasure. Its effect on attitudes is mediated by arousal and pleasure; in addition, the effect on entering intentions is mediated by arousal. Attitudes toward window display also have a positive effect on entering intentions. This study extends existing research on creativity in marketing into the context of visual merchandising in fashion store windows. Findings provide meaningful implications in that the effects of fashion store window creativity on emotions affect consumer attitudes and behavioral intention. By adopting multiple approaches in the empirical phase of this study, the findings are built on strong reliability and validity.

This study was conducted to investigate the mediated effects of self-efficacy in relation to communication competency within the medical team and turnover intention of hospital nurses. Data were collected from 208 nurses working at two university hospitals. In analyzing data using SPSS/WIN 23.0 program, descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and after analyzed with Multiple regression analysis using Baron & Kenny's 3 stage procedure, confirmed indirect effect with Sobel test. Evaluation of relationships among communication competency, turnover intention and self-efficacy of subjects revealed a negative relationship(r=-0.22, p=0.001) between communication competency and turnover intention, a positive relationship(r=0.61, p<0.001) between communication competency and self-efficacy and a negative relationship(r=-0.25, <0.001) between self-efficacy and turnover intention. Concerning the mediated effect of self-efficacy in the relationship between communication competency and turnover intention, the influence of communication competency at stage 1 on turnover intention was significant(${\beta}=-0.22$, p<0.001), but communication competency at stage 3 had no significant influence on turnover intention(${\beta}=-0.11$, p=0.194). Accordingly, the mediated effect of self-efficacy in the relationship between communication competency and turnover intention fully mediated and the mediated effect of self-efficacy was significant(z=-2.15, p=0.032). Heightening self-efficacy by improving communication competency could effectively reduce the turnover intention of nurses.

The purpose of this study was to analyze the effects of children's self-esteem on their school adjustment, focusing on the mediation of peer attachment. A total of 2,200 3rd grade children from the third Korea Child-Adolescent Panel Survey participated in this study. The instruments used in this study were the Self-esteem Scale, Peer Attachment Scale, and School Adjustment Scale. The collected data were analyzed by using a Student's t -test, Pearson's partial correlation, simple regression, and hierarchical multiple regression with SPSS ver. 16.0 software. The main results of this study are as follows: first, the boys had higher self-esteem, peer attachment, and school adjustment scores than the girls. Second, there was a significant positive correlation between children's self-esteem and peer attachment as well as a significant positive correlation between children's self-esteem and school adjustment. Further, there was a significant positive correlation between children's peer attachment and school adjustment. Finally, children's self-esteem exerted positive effects on their peer attachment, and children's peer attachment had a positive influence on their school adjustment. The effect of children's self-esteem on their school adjustment was partially mediated by their peer attachment. These findings provide preliminary evidence that the relationships between children's self-esteem and school adjustment may be mediated by their peer attachment.
