본 연구의 목적은 만 5세 유아-어머니 상호작용의 질과 빈도에 따라 상호작용 유형을 구분하고, 이러한 유형의 분류를 유아의 기질, 어머니의 심리적 건강 및 양육 관련 요인이 예측할 수 있는지 확인하며, 상호작용 유형에 따라 유아의 인지 및 사회정서발달 특성에 차이가 있는지를 밝히는 것이었다. 이를 위해 한국아동패널의 5-7차 연도에 수집된 1,079가구의 자료에 대하여 잠재프로파일 분석, 다항 로지스틱 회귀분석, 그리고 일원변량분석을 실시하였다. 분석 결과 첫째, 유아 어머니의 상호작용 유형은 온정/관여형, 온정/평균형, 통제/제한형의 3개 유형으로 분류되었다. 둘째, 유아 성별과 가족 사회인구학적 변인의 영향력을 제거하였을 때 유아의 활동성 기질, 어머니의 자아존중감과 양육스트레스, 아버지의 양육참여 수준이 어머니의 상호작용 유형을 예측하는 요인으로 나타났다. 셋째, 세 가지 상호작용 유형 중 온정/관여형의 경우 다른 유형보다 이후 유아의 학업능력 및 사회적 유능감 발달 수준이 더 높고 외현화문제는 더 낮은 것으로 나타났다. 본 연구는 유아기 어머니의 상호작용 유형이 상호작용의 질과 빈도에 따라 서로 다른 유형으로 구분되며 유아의 전반적 발달과 관련이 있음을 밝히고, 어머니의 심리적 건강을 지원하는 부모교육과 아버지의 양육참여를 증진하는 정책적 지원의 필요성을 실증적으로 확인하였다는 의의가 있다. This study aims to investigate the types of mother-child interaction according to the quality and frequency of interaction, identify the effects of child temperament, maternal psychological factors, and parenting-related factors on the different types, and analyze differences in cognitive and socio-emotional development of children by the type of interaction. Latent profile analysis, multinominal logistic regression, and one-way ANOVA were conducted using data on 1,079 households from the Panel Study on Korean Children collected from 2012(5th wave) to 2014(7th wave). The main results are as follows. First, the latent profiles of mother-child interaction were classified into three types: warm/high involvement, warm/average involvement, and control/low involvement. Second, when the influence of the child's gender and socio-demographic characteristics were eliminated, the activity temperament of the child, maternal self-esteem and parenting stress, and paternal parenting participation predicted the mother-child interaction type. Third, children of mothers in the warm/high involvement type had higher academic skills and social competence and lower externalization problems than other types. Revealed differences in the overall development of preschoolers according to the type of mother-child interaction, this study empirically confirmed the need for parent education to support maternal psychological health and policy to encourage fathers to participate in parenting.
지하수 내 과불화화합물 제거를 위한 영가철 기반 환원 기술 개발

Perfluoroalkyl acids have been used as components of aqueous fire-fighting foams (AFFFs). Fire-fighting training with AFFFs at military sites has resulted in the contamination of groundwater with perfluorooctonoic acid (PFOA) and perfluorooctanesulfonate (PFOS) at concentrations higher than the US EPA Provisional Health Advisory levels. PFOA and PFOS are resistant to microbial degradation as well as most conventional abiotic techniques. Low heat-activated persulfate oxidation of PFOA has been demonstrated successfully; however, PFOS remained unaltered even at high heat applied. Given the high oxidation state of carbon in the C-S bond of PFOS, reductive technologies are feasible. Therefore, this study assessed the effectiveness of nanoscale zero valent iron (Fe°) coated with palladium (Pd°) at different conditions (mass, intial pH, and heat) and addition of aluminum (Al°) or clay as a another reductant or supporting material, respectively were evaluated. Addition of Pd catalyst enhanced PFOS removal in Pdo/Feo NPs alone system. And use of clay in Pdo/Feo NPs systems also increased PFOA and PFOS removal up to 75% and 95%, respectively. Also, addition of Al increased PFOS removal at acidic pH condition. However, most of PFOA and PFOS removal observed in all assessed systems were due to strong adsorption onto metals not their destruction which were supported by lack of F<sup>-</sup> and SO<sub>4</sub><sup>2-</sup> measurement as products of their destruction.
영아 자녀를 둔 어머니의 양육스트레스 변화가 온정적 양육행동 및 유아의 사회정서발달에 미치는 영향

Objective: This study aimed to investigate the trajectory of maternal parenting stress during infancy according to the employment status of mothers when each year`s depression was controlled and examine the longitudinal effects of parenting stress on affective parenting and socioemotional developmental outcomes for preschoolers. Methods: Using latent growth modeling, the first 4 waves of panel data collected from 2,078 mothers and their babies were analyzed. This nationwide data was provided from the 2008 Panel Study on Korean Children, conducted by the Korea Institute of Child Care and Education. Results: First, maternal parenting stress showed a linear increasing pattern, and there were individual differences in intercept and slope. Second, when each year`s maternal depression was controlled, the intercept of parenting stress was lower, but the rate of increase was higher. In multiple group analyses, this increasing pattern of parenting stress was significant only in unemployed mothers. Lastly, the increase of unemployed mothers` parenting stress had direct effects on child emotionality and peer interaction and had an indirect effect on child peer interaction (mediated by affective parenting). Conclusion: The current study verified that the longitudinal effects of increasing parenting stress of unemployed mothers on affective parenting and child socioemotional development when maternal depression level was controlled. These results imply that we need to pay more attention to emotional health and resources of unemployed mothers and provide them with social support as well as employed mothers.
학부모 교육참여 우수사례 공모사업의 변화와 2019년 우수사례 내용 분석

본 연구의 목적은 2009년부터 2019년까지 시행된 학부모 교육참여 우수사례 공모사업에 나타난 변화와 2019년 학부모 교육참여 우수사례로 선정된 85편의 활동내용 분석을 통해 학부모 교육참여 활성화를 위한 시사점을 도출하는 것이었다. 2015년 이후 사업목적이 학부모 참여를 지원하는 우수사례를 발굴하는 데 보다 초점을 둠으로써 공모대상에서 학교와 지역학부모지원센터의 비중이 증가한 반면, 학부모회의 비중은 크게 감소하였다. 공모분야는 활동주체를 중심으로 점차 통합되어 왔으며, 공모분야 중에서는 교육기부/자원봉사와 학부모교육 분야의 비중이 비교적 높아 현장에서는 학부모가 학교교육의 보조자 및 교육수요자로서 참여하는 경우가 더 많은 것으로 나타났다. 2019년 선정된 우수사례들에 포함된 활동내용 중에서는 학부모교육의 비중이 가장 높았으나, 포상순위가 높은 사례들은 학부모가 교육과정에 주도적으로 참여하는 활동에 중점을 두는 특징을 보였다. 교육주체로서 학부모의 교육참여 활성화를 위하여 향후 학부모 교육참여 우수사례 공모사업에서는 주도적인 학부모회 활동 사례의 비중이 점차 확대되어야 하며, 이를 위하여 학교참여로 연계될 수 있는 학부모교육 등 학부모교육의 질 제고 및 정책적 지원이 필요함을 논의하였다. This study aims to explore the changes of the best practice contest project for parents’ participation in education organized by Ministry of Education from 2009 to 2019, and to analyze the contents of 85 best practices selected from the 2019 contest. Since 2015, as the purpose of contest has focused more on finding best practices to support parents’ participation, the proportion of schools and parent support centers has increased in the contest while the proportion of parents’ associations has decreased considerably. The field of contest has been gradually integrated around the subjects, and the relatively high proportion of volunteering activity and parents’ education showed that parents participated as educational assistants or consumers rather than educational entities. Among the activities included in the selected best practices in 2019, the proportion of parents’ education was the highest, while cases with higher rankings showed a leading participation in school curriculum by parents. It was discussed the necessity for expanding the proportion of parents’ association gradually at the contest in the future and improving the quality of parents’ education which can be linked to school participation.
