이경옥(KyungOk Lee),박혜원(Hyewon Park),이상희(Sanghee Lee) 한국아동학회 2016 아동학회지 Vol.37 No.6

Objective: This study examined the construct validity of K-WPPSI-IV. Factor structures of the structures of the K-WPPSI-IV full scale as well as primary index scales for two age ranges (2 years, 6 months to 3 years, 11 months; 4 years to 7 years, 7 months) were examined. Methods: Data were collected from 1,700 children aged 2 years, 6 months to 7 years, 7 months during the K-WPPSI-IV standardization. Confirmatory factor analyses were conducted using the K-WPPSI-IV subtest performances with maximum likelihood estimation using Amos 18. Results: First, the three-factor model (verbal comprehension, visual spatial, and working memory) fitted best for the younger age range. However, the five-factor model (verbal comprehension, visual spatial, fluid reasoning, working memory, and processing speed) fitted best for the older age range. Residuals suggest the presence of two nested subfactors within the verbal comprehension factor (broad/expressive and focused/simple). Second, the confirmatory factor analysis on primary index subtests identified factors that account for the intercorrelations among the reduced sets of primary index subtests. Conclusion: The findings showed that the theoretical structures of WPPSI-IV subtests were confirmed within K-WPPSI-IV.

이경옥(Lee KyungOk) 한국열린유아교육학회 2003 열린유아교육연구 Vol.8 No.2

본 연구의 목적은 3, 4, 5세의 유치원생(n=201)을 대상으로 유아기 자아개념의 측정모델을 분석하여 유아기 자아개념의 구조를 검토하고 유아의 자아개념 발달을 이해하는데 있다. 연구 결과는 유아의 자아개념의 8개의 하위 영역으로 변별되는 다면적 구조(multidimensionality)를 이루고 있다는 Marsh의 주장과 일치하였다. 또한, Shavelson이 제시한 것처럼 유아의 자아개념 하위영역은 학문적 자아개념과 비학문적 자아개념으로 크게 대별되어 전체적인 자아개념을 구성하는 위계적 구조(hierarchical structure)를 갖는 것으로 나타났다. 가설적 모델의 모델적합도, 요인부하량 및 요인간 상관관계가 이러한 결과를 지지하고 있다. 본 연구 결과는 다른 나라의 유아를 대상으로 한 연구 결과와 일치하여 유아가 자아개념의 발달과 자아개념 척도의 다문화적 타당성에 의미 있는 시사점을 제시하고 있다. Using the confirmatory factor analytic approach, the measurement structure of Self Description Questionnaire I (SDQ-I) was examined with kindergarteners in Korea. The original SDQ-I was translated into Korean, and data was collected from 5 kindergartens in Korea (N=201). The results indicated that SDQ-I was reliable and the 8-factor structure of SDQ-I was well defined with Korean kindergarteners. Factor loadings and factor correlations were also appropriate. The results were consistent with the previous studies. Cross-cultural validation of SDQ-I was supported in this study. For further studies, we plan to include more data with different age groups and also examine age differences in self-concept development.

이정미(Lee Jungmi),이경옥(Lee KyungOk) 한국유아교육·보육복지학회 2016 유아교육·보육복지연구 Vol.20 No.2

본 연구에서는 영아교사의 아동기 부모에 대한 애착 지각과 교사-영아 상호작용 간의 관계에서 정서 노동에 대한 교사의 인식이 지니는 매개효과를 분석하였다. 서울과 경기 지역의 어린이집에 재직 중인 영아반 교사 214명을 대상으로 수집된 자료를 SPSS 18.0과 Amos 21을 이용하여 분석하였다. 각 모델은 부와 모에 대한 영아교사의 아동기 애착지각과 교사-영아 상호작용에서 각 정서노동 하위요인의 매개효과를 분석하였다. 분석결과는 다음과 같다. 첫째, 자연적 정서노동은 교사의 아동기 모에 대한 애착 지각 과 교사-영아 상호작용 간의 관계에서 완전매개 역할을 하였으나 부에 대한 애착 지각은 유의하지 않는 것으로 나타났다. 둘째, 표면적 정서노동은 교사-영아 상호작용과 유의한 관계가 나타났으나, 교사의 아동기 부와 모에 대한 애착 지각과 교사-영아 상호작용 간의 관계에서 매개효과를 나타내지 않아, 영아교사의 아동기 부와 모에 대한 애착 지각은 교사-영아 상호작용에 직접적인 영향을 미치는 것으로 나타났다. 셋째, 내면적 정서노동을 포함한 모델의 경우, 아동기 모에 대한 애착지각은 교사-영아 상호작용에 대해 직 · 간접적인 관계가 나타나, 교사의 아동기 모에 대한 애착 지각과 교사-영아 상호작용의 사이에 서 부분매개 역할을 하는 것으로 확인되었다. This study analyzes the mediating effects of teachers’ emotional labors on childhood attachment perception to the parents and teacher-infant interaction. The participants were 214 teachers in child care center in Seoul and Gyeonggi area. Each model including analyzation of meditator effect, which is found in sub factors in emotional labor, between teacher’s childhood attachment perception and teacher-infant interaction. This research suggests three things. First one is that natural emotional labor is revealed to perform a role of fully-mediating between childhood attachment perception to mother and teacher-infant interaction. In contrast, childhood attachment perception to father was found to have no meaningful effect to teacher-infant interaction. Second, childhood attachment perception to parents of infant teachers had a direct impact on teacher-infant interaction. And superficially emotional labor had meaningful effect on teacher-infant interaction but there is no meaningful effect on childhood attachment perception to parents of teachers. Finally, infant teacher’s childhood attachment perception to mother had its own influence to teacher-infant interaction in direct and indirect ways. This result showed that deep emotional labor was found to have partially-mediating effect on childhood attachment perception to mother and teacher-infant interaction.

이상희 ( Sanghee Lee ),이경옥 ( Kyungok Lee ) 한국어린이문학교육학회 2014 어린이문학교육연구 Vol.15 No.1

본 연구의 목적은 UCR(User Created Robot) 기술을 활용하여 유아교육현장에 적절한 동극활동 을 개발하고, UCR 기술의 유아교육현장 적용가능성을 살펴보는데 있다. 이를 위하여 유아교육현장에서 UCR 기술을 활용한 동극활동을 계획하고 동화내용에 적절한 로봇의 외형을 설계하였다. 또한 로봇의 이동성과 상호작용성에 기초한 로봇콘텐츠를 개발하여 유아가 로봇과 함께 동극활동을 수행할 수 있도록 하였다. 개발된 로봇기술을 활용한 동극활동은 전문가 검토과정을 거쳐 유아교육현장에 적용한 후, 유아와 교사의 반응을 분석하였다. 본 연구를 통하여 유아교육현장에 UCR 기술을 활용한 다양한 로봇콘텐츠의 가능성을 엿볼 수 있었고, 유아들이 로봇과 같이 동극활동을 수행하면서 보다 적극적으로 동극활동에 참여하는 것을 확인할 수 있었다. UCR 기술을 활용한 동극활 동 개발 연구를 통해 사용자가 직접 로봇콘텐츠를 수정·제작함으로써 유아교육현장에서 요구되는 교수매체로서 로봇을 적절히 활용할 수 있으며 유아의 활동을 촉진하는 유용한 로봇콘텐츠 개발에 기여할 수 있을 것이다. This study developed dramatic activities using the UCR(User Created Robot) technology, and examined the applicability of UCR technology in early childhood education. In order to apply the UCR technology on dramatic activities for young children, we designed robots that are suited for a fairy tale and robotic contents based on the mobility and the interactive system of robots to help young children perform dramatic plays with robots. After going through a review process, dramatic activities using UCR technology were analyzed to examine the reactions of young children and teachers in the childhood education field. Through this study, not only could we see the possibility of various robotic contents based on UCR technology, but we could also confirm that young children participated in dramatic activities more enthusiastically when they were performing with robots. Due to the fact that users such as early childhood educators can create robotic contents by themselves, the UCR technology, as a proper instructional medium demanded in early childhood education, can contribute to lots of valuable robotic contents.

유아의 초기 발달수준과 또래상호작용 간의 관계에서 어머니의 사회적 양육행동의 매개효과

이선남 ( Sun Nam Lee ),이경옥 ( Kyungok Lee ) 한국유아교육학회 2015 유아교육연구 Vol.35 No.4

This study examined the mediating effect of mothers’ social parenting behavior on the relationship between children``s early development and peer interaction. For this study, 1,540 participants were analyzed from the 2010 and 2011 data of the Panel Study on Korean Children, with list-wise deletions. Using IBM SPSS Statistics 21 and Amos 21, the correlation among child development(i.e., infant communication, problem behavior, and personal social skills), mother’s social parenting behavior, and peer interaction(i.e., play interaction, play disruption, and play disconnection) were analyzed. There was a significant correlation between peer social interaction and the mother’s social parenting, and this had considerable effect on early childhood development. In particular, the mother’s social parenting behavior was an important mediating factor in the relationship between early child development and peer interaction(both positive peer interactions, such as play interaction, and negative peer interactions, such as play disconnection and play disruption). While it had only a partial mediating effect on the relationship between infant early development and play interaction, the mother’s social parenting behavior had a complete mediating effect on the relationship between infant early development and negative peer interaction(both play disconnection and play disruption). By exploring the relevance and the path of infant early development and social parenting behavior that affects infant peer interaction, this study can contribute to laying the theoretical foundation for mothers’ social parenting behavior that can lead to infants’ pro-social behavior.

SCR 시스템에서 환원제 분사 균일도 개선을 위한 혼합기 설계

황우현(Woohyeon Hwang),이경옥(Kyungok Lee) 한국컴퓨터정보학회 2017 한국컴퓨터정보학회논문지 Vol.22 No.1

In this paper, we propose a method to optimize the geometry and installation position of the mixer in the selective catalytic reduction (SCR) system by computational fluid dynamic(CFD). Using the commercial CFD software of CFD-ACE+, the flow dynamics of the flue gas was numerically analyzed for improving the injection uniformity of the reduction agent. Numerical analysis of the mixed gas heat flow into the upstream side of the primary SCR catalyst layer was performed when the denitrification facility was operated. The characteristics such as the flow rate, temperature, pressure loss and ammonia concentration of the mixed gas consisting of the flue gas and the ammonia reducing gas were examined at the upstream of the catalyst layer of SCR. The temperature difference on the surface of the catalyst layer is very small compared to the flow rate of the exhaust gas, and the temperature difference caused by the reducing gas hardly occurs because the flow rate of the reducing gas is very small. When the mixed gas is introduced into the SCR reactor, there is a slight tendency toward one wall. When the gas passes through the catalyst layer having a large pressure loss, the flow angle of the exhaust gas changes because the direction of the exhaust gas changes toward a smaller flow. Based on the uniformity of the flow rate of the mixed gas calculated at the SCR, it is judged that the position of the test port reflected in the design is proper.

박혜원(Hyewon Park),이경옥(KyungOk Lee) 한국아동학회 2016 아동학회지 Vol.37 No.6

Objective: This study examined the intellectual characteristics of 1,700 Korean children aged 2 years, 6 months to 7 years, 7 months across two age ranges (2 years, 6 months to 3 years, 11 months; 4 years to 7 years, 7 months). Methods: Data from the standardization study of the K-WPPSI-IV were analyzed using Korean and American norms and in terms of socioeconomic variables such as region, maternal education level, and child gender. Results: Korean children performed differently from their American counterparts in most subtests and indexes. Verbal subtest performances for Korean children were significantly lower and performance subtest performances for Korean children were significantly higher. There were significant regional differences, with higher performances among children from Seoul than from other areas. Children whose mothers had higher education levels showed higher performances than their counterparts. This trend was more apparent in the older age range. Gender differences were found in most subtests, with girls showing higher scores than boys. Conclusion: This study revealed cross-cultural differences in intellectual characteristics measured with the newly standardized K-WPPSI-IV. In addition, significant effects of socioeconomic variables such as region, maternal education level, and gender were found.
