The aims of this study were to identify the significant predictors of the sexual behavior of middle school students. The subjects consisted of 603 middle school students (male 344, female 259). The data was collected through self-report questionnaires, which were constructed to include the attitudes to sexual behavior, sexual permissiveness, perceived behavioral control, sexual behavioral intention, father's child-rearing attitudes, mother's child-rearing attitudes, friends' attitudes to sex, exposure to pornography, and sexual behavior. The data was analyzed using the SPSS 19.0 program. The significant predictors of sexual behavior of middle school students that explained 51.0% of the variance in sexual behavior were the friends' attitudes to sex, alcohol drinking experience, experience of sexual abuse, sexual permissiveness, exposure to pornography, sexual behavioral intention, perceived behavioral control, father's child-rearing attitudes, and mother's child-rearing attitudes. These findings suggest that the approach to a sexual education promotion program for middle school students should consider multisystemic predictors.

Transient transfection assay has been done to evaluate whether the c-jun activation would be prerequisite to the induction of permissiveness against human cytomegalovirus using in vitro cell model in which U937 has been induced to express CD11b and CD14 to become potential monocyte/macrophage cells by TPA treatment. U937 cells were treated with $10\;{\mu}M$, $50\;{\mu}M$ or $100\;{\mu}M$ of TPA. The cell morphology change was observed and the expression of the CD11b and CD14 was confirmed by FACS. Differentiated cells were transfected with pJLuc reporter vector which contained the wild type murine c-jun promoter spanning the SP1, CTF, ATF/CREB and MEF-2 binding sites upstream of the firefly luciferase gene. After 48 hrs of transfection, the cells were infected with HCMV Towne strain and the luciferase activity was assessed at 1 hand 4 h pi. The transfection assay showed no activation of the c-jun promoter at 1 h pi, instead, it showed 2 times increase of the its activity at 4 h pi. There was no difference of the c-jun promoter activation between TPA treated and untreated U937 cells, implying that c-jun activation might not be prerequisite for allowing cells to be premissive to HCMV, although HCMV infection itself could activate c-jun promoter.

The purpose of this study is to identify the relationship between sexual attitude and risk behaviors, between risk behavior and sexual experiences in Korean girls high school students. The subjects for this study were 522 girls, who were samples from a target population of 63,375 11th grade students from 200 regular high schools and 70 vocational high schools in Seoul. The data were collected from June 22 to July 18, 2002. A structured questionnaire was used that included measurement of general characteristics, sexual attitudes, risk behaviors and sexual experiences. The data were processed with the SAS program, which uses descriptive statistics, t-test, and ANOVA in its an alyses. The results of this study are as follows : 1. The frequency of sexual experience is as follows ; 'holding hands' had the highest percentage, 57.4 7%, followed in order by 'arms around' 50.19%, 'act of embracing' 50.19%, 'kiss' 37.74%, 'french kiss' 30.84%, 'touch breasts' 8.62%, 'touch sexual organs' 3.26%, 'coitus' 2.30%, 'contraception' 0.77%, 'pregnancy' 0.19%, 'abortion' 0.19%, and 'prostitution' 0.19%. 2. The score of conservatives types was significantly different depending upon exposure to pornographic material and drinking. In comparison, the score of permissiveness types was significantly different depending upon exposure to pornographic material, drinking, and running away from home. But the score of pleasure seeking types was not significantly different than that of the risk behaviors types. 3. There was statistically significant difference in the sexual experience depending upon exposure to pornographic material, drinking, smoking, and running away from home. 4. In the relationship between sexual attitude types and sexual experience, there was a negative correlation between the conservatives types and sexual experiences such as 'holding hands', 'arms around', 'act of embracing', 'kiss', 'french kiss', 'touch breasts', 'touch sexual organs', and 'coitus'. There was a positive correlation between the permissiveness types and sexual experiences such as 'holding hands', 'arms around', 'act of embracing', 'kiss', 'french kiss', 'touch breasts', 'touch sexual organs', and 'coitus'. There was also a positive correlation between the pleasure-seeking types and sexual experiences such as 'touch sexual organ', 'contraceptions', 'pregnancy', and 'prostitution'. Based on the finding of this study, this society should develop a integrated program to prevent risk behaviors and sexual experiences in girls high school students.

The purpose of this study was to explore the currents status of exposure to internet pornography on the part of elementary students and to analyze the impact upon levels of sexual knowledge or sexual attitudes in such children. The participants in this study comprised 536 6th grade elementary school students. The data was analyzed by means of T-tests, F-tests, Pearson's correlation and regression analysis. The results were as follows. First, 32.5% of the subjects had experienced some degree of exposure to internet pornography. Second, sexual attitudes and sexual knowledge were found to be higher in accordance with the general characteristics exhibited by the girls, these same sexual attitudes and sexual knowledge amongst girls were observed to be even higher when they were exposed to internet pornography. Third, the characteristics of this exposure to internet pornography did not significantly impact on levels of sex knowledge. However, the characteristics of exposure to internet pornography did significantly impact upon sexual attitudes. In particular, gender permissiveness, attitudes regarding pornography, and attitudes towards physical contact did have a significant impact.

The purpose of this study was to identify the impact of preschoolers' cognitive ability, parenting behavior, and attachment to their mothers and teachers on delay of gratification of preschoolers. The participants of this study were 116 mothers and their 15 teachers of 3-6 year olds from 2 day-care centers in Seoul. T-test, F-test, Correlation analysis, multiple regression analysis were used for data analysis. First, the result of this study showed that preschoolers' delay of gratification by cognitive ability was significant to only motor intelligence. Second, preschoolers' delay of gratification showed positive correlation with warm-acceptance of parenting. Third, preschoolers' delay of gratification by attachment to their mothers was statistically significant, but it was not significant to their teachers. Fourth, the effect of preschoolers' intelligence, parenting behavior, and attachment to their mothers and teachers on delay of gratification was statistically significant to mothers' warm-acceptance($\beta$=.24, p<.05) and was negatively significant to mothers' permissiveness(.$\beta$=-.35, p<.001).

The relationships of maternal childrearing behaviors and peer experiences to children's self-esteem were examined with a sample of 433 5th- and 6th-grade elementary school students (236 boys and 197 girls) and their mothers. Children answered the questionnaires on peer experience (victimization by peers and peer aggression) and self-esteem, and their mothers answered the questionnaires on maternal childrearing behaviors. Maternal warmth was significantly related to children's self-esteem both in boys and girls. The warmer their mothers, the higher the children's self-esteem. Maternal permissiveness/nonintervention was related to self-esteem only in boys; the more permissive/nonintervention the mothers, the lower the boys self-esteem. Peer experiences (victimization by peers and peer aggression) were significantly related to self-esteem both in boys and girls; the more victimization by peers and peer aggression, the lower their self-esteem. Maternal warmth was related to victimization by peers only in girls; the warmer the mothers, the less victimization by peers experienced by girls. The effect of maternal warmth on self-esteem was mediated by victimization by peers for girls, which indicates that maternal warmth doesn't have a direct influence but an indirect influence on victimization by peers of children. Victimization by peers was related to peer aggression both in boys and girls. The more victimization by peers they experienced, the more peer aggression they showed.

The main purpose of this study was to examine the relationship between mothers' parenting, children's self-esteem, and stress. The participants were composed of 320 elementary school 5th graders (161 boys and 159 girls) from the Seoul area. They completed questionnaires on mothers' parenting, children's self-esteem, and stress. The data were analyzed by means of Pearson's correlation coefficients and regressions. It was observed that maternal warmth was negatively correlated with children's stress in both boys and girls. Children's self-esteem was also negatively correlated with children's stress in both boys and girls. in addition maternal warmth was positively correlated with self-esteem in both boys and girls. It was futher found that self-esteem tended to play a partially mediating role between maternal warmth and children's stress only in boys. Self-esteem tended to play a perfectly mediating role between maternal permissiveness/nonintervention and children's stress only in girls. These results indicated that children's self-esteem plays a crucial role in improving the levels of children's stress.

The purpose of this study is to investigate the impact of mother's and father's parenting behaviors and parenting involvement on prosocial behaviors of preschool children. The data were collected from 149 preschool children and their parents(149 mothers, 149 fathers). The collected data were analyzed by SPSS12.0 program for frequency, percentage, t-test, ANOVA, Duncan's test, multiple linear regression. The findings of this study are as follows :first, preschool children behaved prosocially more when their mothers or their fathers took warmth-acceptance of parenting behaviors. They showed lower prosocial behaviors when their fathers conducted more rejection-restriction or more permissiveness-nonintervention of parenting behaviors. Second, preschool children prosocially behaved more when their mothers and their fathers were more involved in parenting. Third, the most powerful predictor of prosocial behaviors was warmth-acceptance of parenting behaviors of their mothers.

The purpose of this study was to explore the relationships of mother's childrearing behavior, children's behavior problems, locus of control and peer victimization. The subjects were 360 children of 4th and 6th grade and their mothers. The instruments were Peer Victimization Scale, CBCL, Locus of Control Scale for Children, Childrearing Behavior Scale. The major findings of this study were as follows; (1) The type of peer victimization had a significant difference between girls and boys. That is, boys were more focused on overt victimization than girls. There was no significant gender difference in relational victimization, And there was no significant grade difference in overt and relational victimization. (2) Mother's rejection-restriction childrearing behavior, children's social withdrawal behavior problems, extemal locus of control predicted children's peer victimization. 24% of the variance of children's peer victimization was explained by these variables. (3) Mother's rejection-restriction childrearing behavior was the first contribution factor and had a direct and indirect effect through children's locus of control on children's peer victimization. And children's social withdrawal behavior problems was second contribution factor and had a direct effect on children's peer victimization. Children's locus of control had a direct and indirect effect through children's social withdrawal behavior problems on children's peer victimization. Mother's warmth-acceptance and permissiveness-nonintervention childrearing behavior had indirect effect through children's locus of control on children's peer victimization.

The main purpose of this study was to investigate the effects of a mother's big five personality factors and playfulness on maternal parenting behavior. The participants consisted of 270 mothers with young children, aged 3-6 years old. The subjects completed questionnaires on IPIP(International Personality Item Pool), PAS(Playfulness Scale for Adults) and Parenting Behavior. The results were as follows. First, regarding the relationships of the mother'personality and parenting behavior, higher levels of neuroticism(N) in the mothers resulted in lower levels of warmth acceptance(W A) in parenting behavior. Higher levels of extroversion(E), openness(O), agreeableness(A), and conscientiousness(C) resulted in higher levels of W A. In terms of the relationships of the mother's playfulness and parenting behavior, higher levels of playfulness resulted in higher levels of W A. and lower levels of permissiveness nonintervention(P N) and rejection restriction(R R). Second, N, E, C, and a maternal sense of humor had an effect in W A. C was found to have an effect in P N and N was observed to have an effect in R R.
