Purpose: The dental age estimation of children is performed using dental maturity. Postmortem missing of the anterior teeth or the distortion of image of the anterior teeth in panoramic radiographs can make it difficult to analyze the development of the anterior teeth. This pilot study was conducted to derive a new age estimation method based only on the developmental stage of mandibular posterior teeth. Methods: This study was conducted using panoramic radiographs of 650 subjects aged 3 to 15 years old. The dental developmental stages of the lower left first premolar, second premolar, first molar and second molar were evaluated according to the Demirjian's criteria. The intra-/inter-observer reliability was evaluated, and multiple linear regression analyses were performed including the developmental stage of each tooth as an independent variable. Results: The intra-/inter-observer reliability was 0.9626 and 0.8877, respectively, and showed very high reproducibility. Multiple linear regression analyses were performed for males and females, and the age calculation table was derived by obtaining the intercept and the coefficient according to the development stage of each tooth. The coefficient of determination (r²) of the age calculation method was 0.9634 for male and 0.9570 for female subjects, and the mean difference between chronological age and estimated dental age was -0.42 and -0.21, respectively. Conclusions: This pilot study evaluated the developmental stages of four lower posterior teeth in the Korean group according to Demirjian's criteria, and derived age estimation method. The accuracy was lower than when more teeth were used, but it will be useful to estimate age of children when the anterior teeth are difficult to accurately analyze.

Although atypical sensory processing is a core feature of autism spectrum disorder (ASD), there is considerable heterogeneity among ASD individuals in the modality and symptoms of atypical sensory processing. The present study examined visual processing of children with ASD, focusing on the complexity and orientation of visual information. Age- and -IQ-matched Korean children (14 ASD and 14 typically-developing (TD) children) received an orientation discrimination task involving static spatial gratings varied in complexity (simple versus complex) and orientation (horizontal versus vertical). The results revealed that ASD children had difficulty perceiving complex information regardless of orientation, whereas TD children had more difficulty with vertical gratings than horizontal gratings. Thus, group-level differences between ASD and TD children appeared greater when gratings were presented horizontally. Unlike ASD adult literature, however, ASD children did not show superior performance on simple gratings. Our findings on typical and atypical processing of ASD children have implications for both understanding the characteristics of ASD children and developing diagnostic tools for ASD.

The purpose of this study was to provide basic information need to promote early childhood's growth with balanced diet and preferable dietary attitude by observing the provision of food service management in kindergarten in Daejeon. We researched the dietary life of full- and half-day program children and their mothers. A questionnaire survey was conducted with 392 children attending kindergarten and their mothers. The questionnaire items examined general characteristics, dietary life, dietary behavior, frequency food intake etc. The results of the survey were as follows. The frequency of breakfast intake of the half-day program children and their mothers was higher than that of the full-day program children and their mothers. Most of the children had an unbalanced diet about soybean, kimchi, and vegetables, whereas their mothers had an unbalanced diet about processed food In general, the half-day program children showed higher scores than full-day children for the items of the dietary behavior of kindergarten. The dietary attitude and nutrition attitude scores of the half-day program children and their mothers were higher than those of the full-day program children and their mothers.

This study investigated family foster care characteristics according to types of foster parents-surrogate, kin, general parents and predicting factors of foster children's adjustability to new environment. Participants were 618 cases of foster parents in 17 areas of the country through stratified sampling. It was found that the surrogate foster parent, tends to be older, received less education, has lower income, and is in poor health, as opposed to kin parents or general foster parents. There were significant effects of foster parent's age, living arrangement, income, education, consideration of foster child, and the periods of foster care experience as well as child's sex, contact of biological parents on emotional, behavioral, and family relational adjustment of the foster children.

In Korea, overseas adoption has been practiced for more than 50 years. Initially, overseas adoption began with the objective to provide permanent homes for Korean war orphans, including mixed-blood children. From 1953 to 2007, about 160,000 Korean children were placed worldwide through overseas adoption and approximately 70,000 children were adopted in Korea. During that period, Korea developed into one of leading industrial countries in the world and the family norms changed dramatically. Since 1989, the Korean government has made diverse efforts to increase domestic adoptions and to support adopted families through the revisions to Korea's Child Welfare Law. However, it is not enough to reduce overseas adoptions rapidly because the Korean government's economic support for adopted families is not adequate and Korean sentiments regarding adoption have not changed. Being an international adoptee is a unique experience, involving dissimilarities of race, ethnicity, and culture. Clearly, it is very important for us to focus on placing Korean children in the best possible environment. Therefore, Korea must make diverse efforts to reduce overseas adoptions and to encourage domestic adoption. First, Korean society has to try to reduce the number of children who need out-of-home care. Second, the Korean government and people should make an effort to increase domestic adoptions, including adoptions of disabled and older children. Finally, the Korean government and adoption agencies have to provide professional pre-adoption and post-adoption services for international adoptees and adoptive parents.

This study is conducted to understand the meanings and nature of the experience of the physically abused children. This is a phenomenological study utilizing van Manen's method to present the children's inner world. The participants for this study were 10 children, in the age of 8 to 12, who were physically abused by their parents. Data were collected by using semi-structured interviews by the workers who regurally contacted children at the service agencies. Data were analyzed by using 'line by line' reflection by two graduate level students and by the researcher. Eight essential themes were drawn and used for the phenomenological understanding which reveals the meanings given by the children experiencing abuse. There were some suggestions for the abuse counsellors based on these findings.

The purpose of this study was to investigate the overall daily life patterns of young children and to compare the lives of children using a center-based care center with those of children raised at home by their mothers. The subjects, 364 mothers of young children (aged 7~48 month olds), completed questionnaires consisting of items on their children's daily activities. Data were analyzed by descriptive statistics, chi-tests, and t-tests. Our primary findings indicated that on the average children slept for 10 hour 22 minutes and they usually played with their mothers at home. The young children mostly played outdoors two or three days per week and their outings were most commonly visits to relatives on weekends. 45.5% of the total children who participated in this study made use of at least one private education service, and they began to watch TV from 12.22 month olds. Furthermore, the mothers reported that their spouses participated in child rearing less than 1 hour a day.
