This study controlled the socio-demographic variables in order to compare the relative influence of children’s literacy interest and mother-child literacy interaction on the children’s emergent literacy skills. For this study, 137 children aged 5 years old (70 boys, 67 girls) and their mothers from child-care centers located in Seoul and Gyeonggi Province had participated. The collected data were analyzed by t-test, correlation analysis, hierarchical multiple regression analysis using SPSS 23.0 program. The results of this study are as follows. First, there were a partially significant differences in children’s literacy interest, mother-child literacy interaction, and children’s emergent literacy skills depending on children’s gender, the existence/non-existence of a sibling, and the monthly average income of the family. Second, the children’s emergent literacy skills was found to have a significant positive relationship with children’s literacy interest and mother-child literacy interactions. Third, as a result of examining the relative influences of children’s literacy interests and mother-child literacy interactions on the emergence of literacy skills of children, mother-child litearcy interaction was more influential than children’s literacy interest. The results of this is study confirms that mother-child literacy interaction is a powerful factor in explaining children’s emergent literacy skills. These findings provide that a stepping stone to the development of children's emergent literacy skills by scrutinizing the detailed factors that explain children's emergent literacy skills, and are meaningful in that they reveal the factors that need to be considered in order to improve children’s emergent literacy skills. 본 연구는 유아의 출현적 문해 능력에 영향을 미치는 유아의 문해 흥미와 어머니-유아 문해 상호작용의 상대적 영향력을 비교하기 위해 사회인구학적 변인을 통제하였다. 이를 위해 서울 및 경기지역 어린이집에 재원 중인 만 5세 유아 137명(남아 70명, 여아 67명)과 유아의 어머니를 대상으로 유아의 문해 흥미, 어머니-유아 문해 상호작용, 유아의 출현적 문해 능력에 관한 자료를 수집하였고, 자료분석을 위해 SPSS 23.0 프로그램을 사용하여 독립표본 t-검증, 상관분석, 위계적 회귀분석을 실시하였다. 본 연구의 결과는 다음과 같다. 첫째, 사회인구학적 변인에 따라 유아의 문해 흥미, 어머니-유아 문해 상호작용, 유아의 출현적 문해 능력에 차이가 있는지 살펴본 결과, 유아의 문해 흥미, 어머니-유아 문해 상호작용, 유아의 출현적 문해 능력은 유아의 성별, 형제 유무, 가정의 월평균 소득에 따라 부분적으로 유의한 차이가 나타났다. 둘째, 유아의 출현적 문해 능력은 유아의 문해 흥미 및 어머니-유아 문해 상호작용과 유의한 정적 관련이 있는 것으로 나타났다. 셋째, 유아의 출현적 문해 능력에 대한 유아의 문해 흥미, 어머니-유아 문해 상호작용의 상대적 영향력을 살펴본 결과, 유아의 문해 흥미보다 어머니-유아 문해 상호작용의 영향력이 더 큰 것으로 나타났다. 본 연구 결과를 통해 어머니-유아 문해 상호작용이 유아의 출현적 문해 능력을 설명하는 강력한 요인임을 확인하였다. 이러한 본 연구의 결과는 유아의 출현적 문해 능력을 설명하는 세부 요인을 면밀히 조사함으로써 유아의 출현적 문해 능력을 발달시키기 위한 접근의 발판을 마련하였다는 점과 만 5세 유아의 출현적 문해 능력을 향상시키기 위해 중점을 두고 고려해야 할 요인을 밝혔다는 점에서 의의가 있다.

소아청소년 정신의학에서의 동물모델

이서경,반건호 大韓神經精神醫學會 2007 신경정신의학 Vol.46 No.4

In studying child and adolescent psychiatry (CAP), animal models are extremely useful to explore the pathogenesis of disorders or to experiment drugs as substitutes for the human body. Particularly in young children, the accuracy of their ex-pression can be low and there are many restrictions in experiments directly upon the patients including difficulties in medi-cation and tests. However, it is not easy to develop animal models because standards for diagnosis are phenomenological and based on behavioral descriptions. The biggest problem in research using animal models in CAP is that it is difficult to make representative models specific to each disorder. The present study reviewed articles about research with animal models in connection to disorders common in CAP such as autism , Tourette syndrome (TS), attention deficit/hyperactivity disorder (ADHD) and mental retardation (MR). Recent resear-ches through animal models are mainly focused on anatomical studies on sites related to disorders and genetic studies. Although there have been many researches for autism, they still seem to be away from establishing representative models. For TS, it is not easy to make specific animal models because of the complexity of the syndrome, but animal models have been greatly helpful to find pathogenesis and develop remedies for TS. In ADHD, Spontaneously Hypertensive Rats (SHR) model is recog-nized as a fine model. With regard to MR, a majority of studies are gene researches related to known abnormal chromosomes. Throughout this review, authors recognized that only few articles have been published using animal models for CAP in Korea. We hope that research using animal models will be more activated in Korea.

Purpose: Bone morphogenetic protein (BMP) is a potent differentiating agent for cells of the osteoblastic lineage. It has been used in the oral cavity under a variety of indications and with different carriers. However, the optimal carrier for each indication is not known. This study evaluated the bone regenerative effect of rhBMP-2 delivered with different carrier systems. Materials and Methods: 8 mm critical-sized rat calvarial defects were used in 60 male Sprague-Dawley rats. The animals were divided into 6 groups containing 10 animals each. Two groups were controls that had no treatment and absorbable collagen membrane only. 4 groups were experimentals that contained rhBMP-2 only and applied with absorbable collagen sponge($Collatape^{(R)}$), $MBCP^{(R)}$, Bio-$Oss^{(R)}$ each. The histological and histometric parameters were used to evaluate the defects after 2- or 8-week healing period. The shape and total augmented area were stable in all groups over the healing time. Results: New bone formation was significantly greater in the rhBMP-2 with carrier group than control group. rhBMP-2/ACS was the highest in bone density but gained less new bone area than rhBMP-2/$MBCP^{(R)}$ and rhBMP-2/Bio-$Oss^{(R)}$. The bone density after 8 weeks was greater than that after 2 weeks in all groups. However, rhBMP-2 alone failed to show the statistically significant difference in new bone area and bone density compared to control group. Also $MBCP^{(R)}$ and Bio-$Oss^{(R)}$ particles remained after 8 weeks healing period. Conclusion: These results suggest that rhBMP-2 with carrier system is an excellent inductive agent for bone formation and we can use it as the predictable bone tissue engieering technique. Future study will likely focus on the kinetics of BMP release and development of carriers that is ideal for it.

레이저 다이오드를 사용한 비접촉식 노면 관측 시스템

이서경,김용기 한국물리학회 2013 새물리 Vol.63 No.3

The dependence of road conditions on the weather was observed by using a non-contact method. Four types (asphalt, concrete, sidewalk brick, and white-painted brick) of road paving materials could clearly be distinguished by using a single laser diode. Wet and icy road conditions could be identified by analyzing the detected light beam, and the drying times of wet and frozen roads were measured. The single-wavelength technique is limited in identifying road conditions by external environmental factors such as fog, rain,spray, mist, \textit{etc}., so a dual-wavelength technique was developed to remove that limitation. The dual-wavelength technique could also clearly distinguish between the four types of road-paving materials. Real road weather conditions were observed for an actual asphalt road and were clearly distinguished. Therefore, this non-contact dual-wavelength laser-diode road-weather-condition monitoring system should be applicable as a real-time road-surface-monitoring apparatus. 본 연구에서는 레이저 다이오드를 사용하여 비접촉식 방법으로 노면의기상상태를 관측하였다. 단일 레이저 다이오드를 사용하여 4가지 종류의노면 포장재 (아스팔트, 콘크리트, 보도블럭, 흰색 페인트가 칠해진벽돌)를 구분하였다. 노면의 기상상태 (젖음, 결빙)에 따라 수신된 빛의특성을 분석하여 노면의 젖음과 결빙을 구분 하였고, 젖은 노면과 결빙된노면이 건조하는데 걸리는 시간을 측정하였다. 단일 파장을 사용할 경우안개, 비, 물보라, 박무 등의 외부 환경요인에 의해서 노면 관측에한계가 존재하므로 두 개의 파장을 사용하여 노면을 관측하였다. 한파장을 사용했을 경우와 마찬가지로 총 4가지 노면의 종류를 확실하게구분할 수 있었다. 그리고 자연 상태에서 실제 노면의 기상 상태 변화를측정하여 아스팔트의 기상상태를 완벽하게 구분하였다. 따라서 본 연구가실제 도로의 기상상태를 실시간으로 측정할 수 있는 기상 장비로사용가능함을 증명하였다.
