The purpose of the study was to examine the relations of early childhood teachers' resilience, empowerment, and job satisfaction, and to investigate the effects of resilience and empowerment on their job satisfaction. The research subjects were 419 early childhood teachers in charge of 3-5 year olds in kindergartens or daycare centers located in South Korea. The collected data were analyzed using the SPSS 28.0 Program. We calculated the Cronbach's alphas and conducted the descriptive statistical analysis, Pearson's correlation analysis, and multiple regression analysis. The results showed the statistically positive correlations between the major variable. The positive effects of early childhood teachers' resilience and empowerment on their job satisfaction were also found. In the relative influence on job satisfaction, the empowerment was greater than resilience. Based on the study results, we suggest academic and practical importance of early childhood teachers' resilience and empowerment, which enables them dedicate on excellent teaching and caring young children via satisfaction with work settings.

Tetranectin (TN), an adipogenic serum protein, enhances adipocyte differentiation, however, its functional mechanism has yet to be elucidated. In the present study, we investigated the adipogenic function of TN by using medium containing TN-depleted fetal bovine serum (TN-del-FBS) and recombinant mouse TN (mTN). The adipocyte differentiation of 3T3-L1 cells was significantly enhanced by mTN supplementation essentially at differentiation induction, which indicated a potential role of the protein in the early differentiation phase. The adipogenic effect of mTN was more significant with insulin in the differentiation induction cocktail, implicating their close functional relationship. mTN enhanced not only the proliferation of growing cells, but also mitotic clonal expansion (MCE) that is a prerequisite for adipocyte differentiation in the early phase. Consistently, mTN increased the phosphorylation of ERK in the early phase of adipocyte differentiation. Results of this study demonstrate that the adipogenic function of mTN is mediated by enhancing MCE via ERK signaling.

This experiment was carried out to evaluate the effect of early mouse embryonic development in vitro by co-culture with bovine and porcine oviductal epithelial cells (BOEC and POEC). The 2-cell embryos were collected from the oviducts of the superovulated and mated cultured in D-PBS /15% FCS at 48 hours after hCG injection. The in vitro developmental rate of blastocyst formation in the embryos were examined under the fllowing treatments; 1) TCM 199 added 15% HCS, 2) Ham's F-10 added 15% HCS, 3) MediCult IVF medium, 4) TCM 199 added 15% HCS + BOEC, 5) TCM 199 added 15% HCS + POEC, 6) Ham's F40 added 15% HCS + BOEC, 7) Ham's F-10 added 15% HCS + POEC,8) MediCult IVF medium + BOEC, 9) MediCult IVF medium + POEC. For a comparative study of in vitro development for 96 hours after hCG injection, were cultured with oviductal epithelial cell and media only. The obtained results were 2-cell embryos developed to the blastocyst stage in TCM 199, Ham's F-10 and MediCult IVF medium at the rates of 84.4,83.2 and 81.6%. respectively. The higher developmental rates(91~97%) of blastocyst formation was appeared when the embryos were co-cultured with a monolayer of bovine or porcine oviductal epithelial cells in TCM 199 or Ham's F-10 and MediCult IVF media. No significant difference in developmental rates was shown between bovine and porcine oviductal epithelial cells but significant difference in co-culture system in comparison between media only system and co-cultures. In conclusions, oviductal epithelial cells, BOEC and POEC, when co-culture with mouse early embryos improved the rates of development, blastocyst and hatching. Therefore, it is suggested that co-culture system using oviductal epithelial cells improve early embryonic developtnent in mouse.

The state adopts the policies based on the goals pursued by the state and provides a basic policy for administrative activities related to early childhood education. Therefore, early childhood education policy should be established organically in consultant with the social consent in advance. In most countries will bear the costs of child care and early childhood education can reduce the financial burden of parents and early childhood education consumers are able to understand the will of the government to support the child care services, which they need in a variety of way. The conflict is deepening - among policy officials, front-line institutions participating in policy implementation, and parents - surrounding the infant and early childhood education. And the conflict has caused the difference between this policy and claims that cannot find hardly a solution. In this study, we argue how the policy differences between groups involved in the policy to analyze the influence, to find the policy conflict resolution strategies.

The purpose of this study was to assess mental health and quality of life (QOL) including factors influencing QOL among early North Korean defectors in South Korea. Participants were 151 early North Korean defectors residing in a settlement support center. All measures were self-administered. Unlike refugees living in communities, early defectors did not experience a high rate of mental health problems and reported a good QOL. Psychoticism was the most predictive factor affecting QOL. Findings from this study suggest the importance of mental health assessment and support over time. Psychoticism, significant in explaining QOL of early North Korean defectors, needs early diagnosis and treatment to prevent progression. Mental health issues among refugees may not be evident while they are in a structured, supportive environment. Evaluation and treatment are needed over time.
