The purpose of this study is to examine the effects of early full-time nonparental care during infancy/toddlerhood on children's socioemotional behaviors during the preschool period. Subjects for this study were 105 three- to five-year-olds from middle-class families in the U. S. A. Children were assigned to one of three groups according to their early care history. Children's social interactions with peers and caregivers during indoor free-play sessions in day care centers were observed for 20 minutes. The head teachers rated the children's social and emotional behaviors on two questionnaires. Mothers completed the Attachment Q-sort for attachment assessment for the preschoolers. In addition, mothers were asked to fill out a questionnaire on their parenting practices. Children who had received full-time nonparental care during infancy and/or toddlerhood were rated by their teachers as being more intellectually competent than children who did not receive full-time nonparental care during first three years of life. They were, however, rated by teachers and were observed by the researcher as being more aggressive than children with no full-time nonparental care. These children were observed to engage in less wandering/onlooking behaviors than children who had not had any full-time nonparental care. Children's attachment security scores and dependency scores did not differ as a function of early nonparental care histories. When the effects of early care patterns, sex of child, and current attachment security to mothers on aggressive behaviors of the preschoolers were examined by a hierarchical regression model, then any "pure" effects of nonparental care and of attachment security on child aggression were minimal after controlling for family background, child care center quality, and maternal childrearing practices. Strong buffering factors for the preschool children (family characteristics, parenting styles, and high quality nonparental care) mediated a possible risk factor of early nonparental care and promoted optimal outcomes for the children.

최근 미국 휴스턴에서 실시된 대규모 시험포장에서 포설계절이 콘크리트포장의 시공초기의 균열발생 패턴에 큰 영향을 준다는 사실이 발견되었는데, 그 내용은 더운계절 시공은 선선한 계절의 시공보다 훨씬 많은 초기균열을 유발시키며, 더운계절시공의 경우 아침일찍 포설한 부분이 오후에 포설한 부분보다 훨씬 많은 초기균열을 유발시킨다는 것이다. 여기서 초기 균열이라 함은 포설후 며칠 이내에 발생하는 균열을 말하며, 대체로 균열틈이 과도하게 벌어지고 균열모양도 구불구불하여 결과적으로 콘크리트 포장 수명단축의 원인이 되는 균열들을 말한다. 본 연구의 목적은 콘크리트 포장의 시공에 있어서 어느 계절에 포설했는지 또는 하루중 몇시쯤에 포설했는지 하는등 포설시기가 콘크리트포장의 초기 균열 발생에 미치는 영향을 파악하고 그 원인을 규명하는데 있다. 본 연구에서는 이러한 포설 시기의 영향을 시멘트의 수화작용(hydration)과 외부온도 조건간의 상호 작용을 규명함으로써 설명하였다.

Objective: The purpose of this study was to examine the effects of authentic parental competence and awareness of early childhood educational community on the life satisfaction of mothers with preschoolers depending on mothers' employment status. Methods: A total of 238 mothers (98 employed, 130 unemployed) whose children were attending early childhood institutes participated in a survey measuring three variables. Results and Conclusion: The findings of the study were as follows: First, there were positive correlations between authentic parental competence, awareness of early childhood educational community, and life satisfaction, regardless of employment status. Second, comparing employed mothers with unemployed mothers, a common variable affecting life satisfaction was social competence, a sub-variable of authentic parental competence. Further, self-system competence, a sub-factor of authentic parental competence, influenced life satisfaction for employed mothers, and sharing core values, a sub-variable of awareness of the early childhood educational community, influenced life satisfaction for unemployed mothers.

저선량 방사선조사에 의한 참박의 초기생육과 유묘 생리활성에 미치는 영향을 보고자 세 품종의 참박종자에 ${\gamma}$선을 $0.5{\sim}30\;Gy$까지 조사하여 온실에서 재배하며 관찰한 결과는 다음과 같다. 저선량에 의한 참박의 초기생육 효과는 품종에 따라 다른 경향을 보였는데 종자발아율의 경우는 대체로 2 Gy와 8 Gy에서 효과가 있었고, 초기생육에서는 Patner와 Support 품종에서는 4 Gy, 16 Gy, 20 Gy 조사구에서, FR용자는 1 Gy 조사구에서 효과적으로 증가하였다. 저선량 ${\gamma}$선을 조사한 참박 유식물체의 엽록소함량은 생육과 어떠한 경향을 보이지 않았으나 초기생육과 항산화효소 활성은 저선량 조사에 의해 대체로 증가하는 경향을 보였다.

Objective: The goal of this study was to investigate the effects of early childhood teachers' current working conditions such as welfare and wages, working hours, ECEC center's environmental characteristics, and parental involvement and community engagement on the professionalism of teachers. Method: A total of 988 respondents participated in the nationwide online survey. The data were analyzed by correlation analysis and structual equation modeling. Results: First, there were no statistically significant direct effects of ECEC teachers' working conditions on teacher professionalism. Second, there were significant direct effects of teacher efficacy and well-being on teacher professionalism. Third, there were significant indirect effects of teachers' working conditions on their professionalism, via efficacy and well-being, linking the impact of working conditions and the professionalism of teachers. Conclusion/Implication: The results of this structural model imply that policy input for teacher welfare, wage increases, and the enhancement of teachers' well-being and efficacy are valid and significant for the professional development of ECEC teachers. These results provide the data-driven evidence for the importance of welfare and socio-cognitive approaches for teachers.

Background: Fenbendazole, a dewormer drug, is used widely in the clinical treatment of parasite infections in animals. Recent studies have shown that fenbendazole has substantial effects on tumor growth, immune responses, and inflammatory responses, suggesting that fenbendazole is a pluripotent drug. Nevertheless, the antiviral effects have not been reported. Fenbendazole can disrupt microtubules, which are essential for multiple viruses infections, suggesting that fenbendazole might have antiviral effects. Objectives: This study examined whether fenbendazole could inhibit bovine herpesvirus 1 (BoHV-1) productive infection in cell cultures. Methods: The effects of fenbendazole on viral production, transcription of the immediate early (IE) genes, viron-associated protein expression, and the cellular signaling PLC-γ1/Akt pathway were assessed using distinct methods. Results: Fenbendazole could inhibit BoHV-1 productive infections significantly in MDBK cells in a dose-dependent manner. A time-of-addition assay indicated that fenbendazole affected both the early and late stages in the virus replication cycles. The transcription of IE genes, including BoHV-1 infected cell protein 0 (bICP0), bICP4, and bICP22, as well as the synthesis of viron-associated proteins, were disrupted differentially by the fenbendazole treatment. The treatment did not affect the cellular signaling pathway of PLC-γ1/Akt, a known cascade playing important roles in virus infection. Conclusions: Overall, fenbendazole has antiviral effects on BoHV-1 replication.

본 연구의 목적은 유아교사의 직무스트레스와 그릿이 이직의도에 미치는 영향을 알아보는 것이다. 이를 위해 수도권에 소재한 유아교육기관에서 근무 중인 유아교사 395명을 대상으로 설문지 조사를 실시하여 이직의도, 직무스트레스, 그릿을 측정했다. 수집된 자료는 SPSS 22.0을 사용하여 분석했으며 기술통계분석, Pearson 상관분석, 위계적 회귀분석을 실시했다. 연구결과로는 첫째, 유아교사의 직무스트레스가 높을수록 이직의도가 높았으며, 그릿이 높을수록 이직의도가 낮게 나타났다. 둘째, 유아교사 직무스트레스와 그릿은 이직의도에 유의한 영향을 주었으며, 직무스트레스의 하위요인 중 행정지원, 업무관련, 경제적 안정, 시설실비는 부적 영향을 미친 반면, 그릿은 정적 영향을 주는 것으로 밝혀졌다. 유아교사의 이직은 유아와 유아교육의 질 및 자신에게 부정적 영향을 줄 수 있으므로, 본 연구결과는 직무스트레스를 감소시키고 그릿을 증진시키는 노력이 요구됨을 시사한다.

Objective: This study investigated how early childhood teachers'creativity and teaching flow was associated with their job satisfaction and examined the mediating effect of teaching flow. Methods: Participants were 222 early childhood teachers in Seoul. Descriptive statistics for all study variables were computed. To examine the hypothesized model and the alternative model structural equation modeling (SEM) was used. Results: The results revealed that early childhood teachers'creativity and teaching flow were positively associated with their job satisfaction. Early childhood teachers'creativity had an influence on their teaching flow, however, it didn't have a direct affect on their job satisfaction. Early childhood teachers' teaching flow had an affect on their job satisfaction. Additionally, early childhood teachers'teaching flow mediated the effects of teachers' creativity on their job satisfaction. Conclusion/Implications: In conclusion, early childhood teachers'teaching flow was a key predictor in the relationship between teachers' creativity and job satisfaction. This study provides guidelines for interventions aimed at increasing the job satisfaction of early childhood teachers.
