Invasion of trophoblasts into maternal uterine tissue is essential for establishing mature feto-maternal circulation. The trophoblast invasion associated with placentation is similar to tumor invasion. In this study, we investigated the role of KAI1, an anti-metastasis factor, at the maternal-fetal interface during placentation. Mouse embryos were obtained from gestational days 5.5 (E5.5) to E13.5. Immunohistochemical analysis revealed that KAI1 was expressed on decidual cells around the track made when a fertilized ovum invaded the endometrium, at days E5.5 and E7.5, and on trophoblast giant cells, along the central maternal artery of the placenta at E9.5. KAI1 in trophoblast giant cells was increased at E11.5, and then decreased at E13.5. Furthermore, KAI1 was upregulated during the forskolin-mediated trophoblastic differentiation of BeWo cells. Collectively, these results indicate that KAI1 is differentially expressed in decidual cells and trophoblasts at the maternal-fetal interface, suggesting that KAI1 prevents trophoblast invasion during placentation.

Purpose: This study aimed to describe knowledge status of current research related to maternal adaptation of women immigrants by marriage in Korea. Methods: Eighteen quantitative current researches published from January, 2006 to August, 2014 that met the inclusion and exclusion criteria. These 18 articles finally selected for systemic review from 5,168 articles. All current researches included the mother within one year after childbirth and one variable related to maternal adaptation at least. Results: Variables related to psychological adaptation (48.1%) were mostly studied. In detail, parenting stress (17.3%) and parenting competency (15.4%) were frequently surveyed. Also, social support (7.7%), husband rearing support (5.8%) of relational adaptation, and acculturation (3.8%) of cultural adaptation were importantly studied. In addition, frequently used instruments for each study variable were analyzed and evaluated. As major results, parenting stress and parenting efficacy were significantly influenced by social support or husband rearing support and acculturation, and had an effect on parenting behaviors. Various maternal education programs were effective in improving maternal role confidence or parenting efficacy and decreasing parenting stress. Conclusion: Nursing intervention programs for improving maternal adaptation should focus on decreasing parenting stress and increasing parenting efficacy by improving social support and acculturation level of women immigrants by marriage in Korea.

Little is known about the relationship between fathers and their preadolescent children in Korea or about variations in fathering by SES and sex role orientation. The purpose of this exploratory research was to examine variation in contemporary Korean fathering (e.g., warmth of fathering, frequency of father involvement, and task share of father involvement) and its influence on children's sex role development. One hundred and twenty-nine fathers, mothers, and their 11-13-year-old children completed standardized survey questionnaires addressing their childrearing practices, parental role involvement, spousal support, and sex role orientations. Data were analyzed using MANOVAs, t-test, correlational analyses, and multiple regression analyses. Mothers reported more warmth in parenting than did fathers. Regardless of sex of child middle class fathers reported more warmth than lower class fathers and lower frequency of task share than lower class fathers. Regardless of SES, fathers with working wives reported higher levels of task share of involvement relative to their spouse. Fathers who were more frequently involved with their children tended to receive greater support from their wives for paternal involvement. There were no differences in parenting by sex of child nor was fathering associated with children's sex role orientation. Girls' femininity was related to fathers' masculinity. SES, maternal support, fathers' femininity, parents' education level, and maternal work status had predictive ability for the ecological view that fathering is a dynamic process predicted by personal characteristics as well as contextual factors.

The present study was designed to answer the following questions: 1) Is there and relationship between the adolescent's sex role identity and perceived parent behavious? 2) Is there any gender differences in perceived parent behavious? 3) Is there any interaction effect between sex role identity and gender in perceived parent behaviors? 109 male and 101 female undergraduates from the five universities in Seoul served as subjects in this investigation. Subjects were administered the Parent Behavior From (PBF) and the Bem Sex Role Inventory (BSRI) in counterbalanced order. A4 (sex-role identity)×2(gender) multivariate analysis of variance was performed for the perceived paternal and maternal behaviors separately. The simultaneous confidence intervals for pairwise comparison were followed when the MANOVA was significant. In testing all hypotheses, .05 was used as a significance level in this study. For the perceived paternal behavious, 1) The androgynous group, compared with the undifferentiated group, reported greater father warmth, active involvement, greater encouragement of cognitive independence, cognitive curiosity, cognitive competence, achievement control, and conformity. 2) The androgynous individuals showed higher father warmth, congitive independence, curiosity, and cognitive competence than the feminine individuals. 3) The androgynous individuals were found to have significantly higher father warmth than the masculine individuals. For the perceived maternal behaviors, there was a significant difference between gender groups in conformity. Daughters reported higher conformity than sons. The interaction effect between sex-role identity and gender, however, was not found to be significant.

This study determines the factors that contribute to the sense of self-identity for children from multicultural and rural families and provides a systematic understanding of individual self-identity. It also provides implications on how parents, teachers, and professionals can approach their role when instructing and rearing children of different sociocultural backgrounds. The subjects consist of the 310 children from multicultural families (Korean fathers and immigrant mothers) residing in South Korea and 280 children from rural families with similar conditions to those in multicultural families in North Jeolla Province South Korea. The sense of self-identity and maternal parenting behavior were perceived differently by children of multicultural and rural families, whose sense of self-identity was affected by school satisfaction and maternal parenting behavior.

The purpose of this study was to examine the relations of mother-adolescent relationships and adolescents' self-esteem to their achievement motivation. The mediating role of adolescent' self-esteem was also explored in the relations between mother-adolescent relationships and their achievement motitation. The subjects of this study consisted of 284 2nd-grade middle school students living in D city. The major findings were that adolescents who experienced higher maternal warmth showed higher achievement motivation, while those who experienced higher maternal rejection/restriction showed lower achievement motivation. Adolescent who experienced higher open family communication reported higher achievement motivation, and those who experienced higher problem in family communication reported lower achievement motivation. The higher self-esteem was, the higher adolescents' achievement motivation was. Adolescents' self-esteem mediated in the relations between maternal rejection/restriction and problems in family communication and their achievement motivation.

The purpose of this study is to examine the relationships between children's roles, parental attachment, teacher's concerns and school adjustment among Children's Alcoholics(COAs). Participants were 2,803 middle and high school students in Seoul. The regression analysis results showed that hero role was positively associated with school bonding and academic performance but increased the level of anxiety/depression. Meanwhile, scapegoat and lost children's roles were negatively associated with school bonding and also increased the level of anxiety/depression. Mascot role were positively associated with school bonding and academic performance but had no relation with anxiety/depression. Regarding moderating effects, maternal attachment moderated the relationship between scapegoat role and school bonding while teacher's concerns moderated the relationship between hero role and anxiety/depression, and the relationship between scapegoat role and anxiety/depression. These findings suggested that practitioners need to consider the contributions of children's roles on school adjustment and moderating effects of maternal attachment or teacher's concerns when intervention programs are developed to improve school adjustment among COAs.

Epidemiological studies suggest that maternal infection, maternal stress, and environmental risk factors during pregnancy increase the risk of brain development abnormalities associated with cognitive impairment in the offspring and increase susceptibility to schizophrenia and autism spectrum disorder. Several animal models have demonstrated that maternal immune activation (MIA) is sufficient to induce abnormal brain development and behavioral defects in the fetus. When polyinosine:polycytodylic acid (poly I:C) or lipopolysaccharide (LPS), which is commonly used in maternal immune activation animal models, was introduced into a pregnant dam, an increase in pro-inflammatory cytokines and microglial activity was observed in the offspring's brain. Microglia are brain-resident immune cells that play a mediating role in the central nervous system, and they are responsible for various functions, such as phagocytosis, synapse formation and branching, and angiogenesis. Several studies have reported that microglia are activated in MIA offspring and influence offspring behavior through interactions with various cytokines. In addition, it has been reported that they play an important role in brain circuits through interactions with neurons and astrocytes. However, there is controversy concerning whether microglia are essential to brain development or lead to behavioral defects, and the exact mechanism remains unknown. Therefore, for the potential diagnosis and treatment of brain developmental disorders, a functional study of microglia should be conducted using MIA animal models.

This study analyzes movie by individualiztion theory of JUNG. It is about the mother and the boy who killed the family and a lot of people based on the original novel of the same name. Movies based on maternal love express the maternal sublime devoted to their children, or act as a genre film that introduces maternity even against social myth or ethics. It expresses the desire of a woman to clash with maternity and raises questions about maternal ideology.The maternal ideology was a modern product had fixed sex role in industrialized societies.As a resukt, maternal love is identified with femininity unlike paternal love. Women are emphasized to be responsible for raising safe social members beyond individual responsibility. The movie develop story about crime that occurred in motherson relationship which lacks attachment formation in fostering process. This is not a recuurence of the maternal ideology of mother who miscarried child because she lacked motherhood. Mother Eva projected a conflict that is between maternal ideology and her desire on motheson relationship.Son Kevin also experiences a projection that influenced his persona through his mother. In this paper, I analyze through JUNG's individualization theory that The characters face their projected ego and realize self-fulfillment by searching of their own life goal out of external role or ideal.
