The purpose of this study is to analyze the influence of career support and teacher relations of parents in order to determine the career determination of multicultural youths, and to confirm the influence of career preparation between parental career and care support and teacher relations. To this end, data from 2017 (the 7th year) was used among the data from the Multicultural Youth Panel Survey (MAPS). According to the analysis results, first, career support, teacher relations, and career preparation of multicultural youth parents have a positive impact on career determination. Second, the importance of the relative influence of career preparation, which is an internal context factor, was also confirmed in the process of determining the career path of multicultural youths. Third, it was analyzed that the higher the career and childcare support of multicultural youth parents, the more positive the teacher relationship, the higher the career determination. Career preparation was confirmed to play a role in mediating career support and teacher relations among multicultural youth parents in determining career paths. Based on the results of this analysis, practical alternatives were proposed to enhance the career determination of multicultural youths.

A radioresistant cell line was established by fractionated ionizing radiation (IR) and assessed by a clonogenic assay, flow cytometry, and Western blot analysis, as well as zymography and a wound healing assay. Microarray was performed to profile global expression and to search for differentially expressed genes (DEGs) in response to IR. H460R cells demonstrated increased cell scattering and acidic vesicular organelles compared with parental cells. Concomitantly, H460R cells showed characteristics of increased migration and matrix metalloproteinase activity. In addition, H460R cells were resistant to IR, exhibiting reduced expression levels of ionizing responsive proteins (p-p53 and ${\gamma}$-H2AX); apoptosis-related molecules, such as cleaved poly(ADP ribose) polymerase; and endoplasmic reticulum stress-related molecules, such as glucose-regulated protein (GRP78) and C/EBP-homologous protein compared with parental cells, whereas the expression of anti-apoptotic X-linked inhibitor of apoptosis protein was increased. Among DEGs, syntrophin beta 2 (SNTB2) significantly increased in H460R cells in response to IR. Knockdown of SNTB2 by siRNA was more sensitive than the control after IR exposure in H460, H460R, and H1299 cells. Our study suggests that H460R cells have differential properties, including cell morphology, potential for metastasis, and resistance to IR, compared with parental cells. In addition, SNTB2 may play an important role in radioresistance. H460R cells could be helpful in in vitro systems for elucidating the molecular mechanisms of and discovering drugs to overcome radioresistance in lung cancer therapy.

The purpose of this study was to analyze the effects of parenting beliefs and maternal gatekeeping on father's parenting involvement. The participants were comprised of 459 Korean and Chinese couples with children whose ages ranged from 3 to 5 years old. The subjects completed questionnaires on the BCPRS (Beliefs Concerning the Parental Role Scale), the PRI (Parental Regulation Inventory), and the parenting involvement sub-scale of the productive father's parenting scale. The main results were as follows. First, in the father's parenting involvement sub-scale, Korean fathers showed a higher value compared to Chinese fathers. Second, Korean mothers had non-traditional parenting beliefs than the Chinese mothers had. Third, in regards to maternal gatekeeping, Chinese mothers more frequently controlled father's parenting than Korean mothers. Fourth, it was found that parenting beliefs and maternal gatekeeping in both countries had a significant influence in father's parenting involvement.

Mothers play a major role in children's consumer socialization but little is known about differences in mother's consumer socialization tendencies and the antecedents causing the differences. This study addresses two research questions: First, what are the underlying dimensions of mother's consumer socialization? Second, what are the antecedent variables causing differences in mother's consumer socialization tendencies; can parental style, consumption-related attitudes (attitude toward marketplace and ads., attitude toward consumerism and consumption-oriented attitude) be used as a conceptual basis for hypothesizing these differences? The findings of this research were as follows: 1. Factor analysis suggested five underlying dimensions of mother's consumer socialization of children; Mother-child communication about consumption, Mediation of media, Reaction to purchase requests, Restriction of allowances and Restriction of consumption. 2. The differences in the mother's consumer socialization tendencies among different parental groups matched the differences in child-rearing behaviour suggested by Developmental Psychology and this provided support for expected relationships between general-consumer socialization tendencies, as measured by mothers' behaviour. 3. Differences were found on all factors according to mothers consumption-related attitude. This provided support for the expectation that mothers' consumption related attitudes are important antecedent variables causing differences in consumer socialization tendencies. Some implications and directions for future research were discussed.

The role of CRE1 in a thermophilic fungus, Myceliophthora thermophila ATCC42464, was studied using RNA interference. In the cre1-silenced strain C88, the filter paper hydrolyzing activity and β-1,4-endoglucanase activity were 3.76-, and 1.31-fold higher, respectively, than those in the parental strain when the strains were cultured in inducing medium for 6 days. The activities of β-1,4-exoglucanase and cellobiase were 2.64-, and 5.59-fold higher, respectively, than those in the parental strain when the strains were cultured for 5 days. Quantitative reverse-transcription polymerase chain reaction showed that the gene expression of egl3, cbh1, and cbh2 was significantly increased in transformant C88 compared with the wild-type strain. Therefore, our findings suggest the feasibility of improving cellulase production by modifying the regulator expression, and an attractive approach to increasing the total cellulase productivity in thermophilic fungi.

This study sought to illuminate a moderating effect of mother's perception of father's involvement on the associations between mother's parenting efficacy and child's emotional regulation. The participants in this study comprised 292 mothers whose children were aged between 4 and 5. The children were attending child care centers or kindergartens located in Seoul or Gyeonggi-do province in Korea. The questionnaires on mother's parental efficacy, father's parental involvement, and their children's emotional regulation were distributed to mothers through their child care centers or kindergartens. The results indicated a significant correlation among the variables. Although mothers' parenting efficacy had relatively higher effects upon their children's emotional regulation than their fathers' involvement, the effect of a fathers' involvement was still significant. In particular, the fathers' involvement in leisure activities moderated the effects of the mothers' parenting efficacy on children's emotional comprehension and regulation(one of the sub-factors of emotional regulation).

Even though gratitude is considered as an important virtue to possess for successful adulthood, little is known about what cultivates gratitude and its benefits associated with psychological well-being among adolescents. By examining gratitude as a daily mood, this study asked (1) whether adolescents' daily grateful mood varied as a function of daily parental emotional support and (2) whether adolescents' psychological well-being varied as a function of daily grateful mood within person across seven days. The sample consisted of 70 adolescents in 8th grade recruited from a public middle school. Participants completed daily diary checklists online each evening for seven days. On days when adolescents perceived greater parental emotional support from mother or father than they typically did during the week, they rated their grateful mood to be higher than other days. With more emotional support from father, adolescents reported more grateful mood not only on that day, but also the following day. While this result highlights the important role that parents play in adolescents' experience of grateful mood, emotionally supportive behaviors of fathers appear particularly promising for cultivating gratitude. Further, daily grateful mood on a given day accounted for the significant variance in adolescents' psychological well-being not only on the same day, but also the following day. Research and practical implications of the results are discussed.

Objective: This study aimed to examine the mediation effects of parenting style and daily activity on the relationships between cumulative parental stress and cognitive and language development of children. Methods: The participants of this study were 1,154 mothers, their five-year-old children, and teachers enrolled in the population-based study of the Panel Study of Korea Children (PSKC) conducted by the Korea Institute of Childcare and Education from 2008 to 2013. In order to analyze the data, descriptive analysis, Pearson correlation analysis, and structural equation modeling were used. Results: The results revealed that warm parenting style as well as daily activity had dual mediating effects between cumulative parental stress and child development (cognitive and language development). However, warm parenting style did not have any direct effects on child development in this model. Conclusion/Implications: Given that actual mother-child daily activity had an important role in affecting child development, support programs for parenting should include activities that include specific materials and activities which parents can do with their children in everyday life.

The purpose of this study was to explore the effects of mothers' self-efficacy, parenting behaviors, and children's achievement motivation on children's self-efficacy. Subjects were 591 fifth- and sixth-graders and their mothers in Busan. Statistics and methods used for data analysis were Cronbach's alpha, Pearson's correlation, Multiple Regression, and Path Analysis. Several major findings of this study were as follows: 1) Any difference was not found by sex in children's general and total self-efficacy. Girls' social efficacy, however, was higher than boys'. 2) Achievement motivation had a direct positive effect and was the first positive contribution factor to the self-efficacy of both sexes. 3) On boys' self-efficacy, mothers' own had an indirect positive effect through achievement motivation, and their parental role efficacy had a positive effect, direct or indirect, through their affective parenting behaviors and the boys' achievement motivation; also mothers' affective parenting behaviors had an indirect positive effect through achievement motivation, and their controlling parenting had a direct negative effect. 4) On girls' self-efficacy, mothers' own had a direct positive effect, and their parental role efficacy had an indirect positive effect through their affective and controlling parenting behaviors and the girls' achievement motivation; also mothers' affective parenting behaviors had a positive effect, direct or indirect, through achievement motivation, and the controlling parenting had a negative effect, direct or indirect.

The purpose of this study was to identify the relationship of job stress, parenting stress and parenting behaviors in nurses. This research was carried out targeting 201 nurses in total who have preschool children and work at two university hospitals and three general hospitals in D Metropolitan. For the analysis of the research SPSS 17.0 was used for the data analysis. Regression analysis was the statistical method used for data analysis. There were significant negative correlations for parenting behavior and parenting stress in the mothers. Among daily lived stress, parental role stress and job stress significantly influenced parenting behavior. Therefore, daily life stress, job stress and parental role stress had an influence on the parenting behavior. The results of this study show that parenting stress, job stress are powerful factors for understanding parenting behavior. An important implication of this study is that nurses in future should be considered with the parenting stress and job stress.
