The purpose of this study is to investigate the relationship between family environment and developmental delay in a sample of normal 3-5 years old children. Developmental evaluation is performed using K-DDST II and K-ASQ. Family environment is researched by survey. The survey questions include children's order, family numbers, religion, patient's age, patient's education history. Subject is selected between the age of 3-5 years old children. The test has been conducted to find an interrelationship between a developmental delayed result and family environment. Study has found that there is a strong relationship between developmental delay and children's family environment. Family environment factor includes children's gender, birth order, parent's age, education history. Therefore, developmental evaluation must have consideration on the element of children's family environment for developmental delay test because of a strong relationship between family environment and developmental delay result.

Purpose: This study examined the perceived quality of life of families of individuals with developmental disabilities who regularly participate in physical activities. It also explored differences in the quality of family life based on variables such as family relationships, family income, gender, disability type, and age. Methods: A survey was administered to 69 family members of individuals with developmental disabilities who regularly participate in physical activities. The collected data were analyzed using descriptive statistics, independent samples t-test, and one-way analysis of variance. Results: The average overall quality of life for families of individuals with developmental disabilities who participate in continuous physical activities was 3.49. After analyzing each subtype, psychological health was found to be 3.91, the burden for people with developmental disabilities was 2.75, community participation was 3.76, cohesion was 3.83, and openness was 3.49. No statistically significant differences were found in family relationships or family classes, disability type, age, or gender of the individuals with developmental disabilities across the variables. Conclusion: When planning service development and support to improve the quality of life for families of individuals with developmental disabilities, it is necessary to develop systematic programs at the family level rather than providing support based on various variables.

This study examined the characteristics of the relationship of HOME, sociodemographic variables and children's verbal ability at age four, five, six, Expecially this study investigated causal relationships amoong the variables which are supposed to affect children's verbal ability by children's age and sex. The subject of this study were 180 children and their mothers. Instruments included inventory of home stimulation(HOME), inventory of socio-demographic variables, inventory of the children's verbla ability. The results obtained from this study were as follows : 1. For the most part, HOME and socio-demographic variables had a significant positive correlation with children's verbal ability. 2. The variables that significantly predicted children's verbal ability differed according to children's age and sex. That is, play materials, breadth of experience and economic status of the home were predictive of boy's verbal ability at age four, while aspects of physical environment, breadth of experience were predictive at age five, fostering maturity and independence, parent's education were predictive at age six. And developmental stimulation and breadth of experience were predictive of girl's verbal ability at age four, while developmental stimulation, economic status of the home were predictive at age five, developmental stimulation and play materials were predictive at age six. 3. the results of the analysis of the causal model showed that the kind of variables that affected children's verbal ability directly differed according to children's age and sex. That is, indirect stimulation and direct stimulation affected boy's verbal ability directly at age four and five, while indirect stimulation and parent's education affected boy's verbal ability at age six. And indirect stimulation, direct stimulation, emotional climate of the home affected girl's verbal ability directly at age four, while direct stimulation, economic status of the home, indirect stimulation affected directly at age five, parent's education, indirect stimulation and direct stimulation affected girl's verbal ability at age six. 4. Another causal model of the HOME, socio-demographic variables affecting children's verbal ability showed that total HOME scores more significantly affected boys and girl's verbal ability directly than socio-demographic variables at all ages.

The developmental age of permanent teeth was evaluated in children and adolescents according to age and gender using the Nolla Method. A retrospective study was performed on panoramic radiographs of 1,200 subjects aged 4-15 years, including 50 children for each age/gender group. Three well-trained examiners estimated the developmental stage of upper and lower permanent teeth using the Nolla Method. The inter-examiner reliability was excellent (intra-class correlation coefficient value = 0.973). The mean developmental age was calculated. In boys, Nolla stage 6, indicated by crown completion, was seen in the central incisor, lateral incisor, canine, first premolar, second premolar, first molar, and second molar at 5.4, 6.4, 6.7, 7.5, 7.8, 4.6, and 8.1 years, respectively, in the maxilla and at 4.8, 5.1, 6.0, 6.5, 7.2, 4.5, and 8.0 years, respectively, in the mandible. In girls, Nolla stage 6 was seen at 5.3, 6.0, 6.3, 7.3, 7.7, 4.8, and 8.1 years, respectively, in the maxilla and at 4.8, 5.1, 5.9, 6.5, 7.2, 5.0, and 7.9 years, respectively, in the mandible. In this study, the developmental age of permanent teeth was evaluated in Korean children and adolescents who visited Yonsei University Dental Hospital. This study may be helpful in diagnosis and treatment planning in the clinic.

Purpose: From the holistic environmental perspective, individual and environmental influences on low-income children's questionable development were identified and examined as to differences in the influences according to the child's developmental stage of infancy (age 0-35 months) or early childhood (age 36-71 months). Methods: This study was a cross-sectional comparative design using negative binominal regression analysis to identify predictors of questionable development separately for each developmental stage. The sample was comprised of 952 children (357 in infancy and 495 in early childhood) from low-income families in South Korea. Predictors included individual factors: child's age and gender; proximal environmental influences: family factors (family health conditions, primary caregiver, child-caregiver relationship, depression in primary caregiver) and institution factors (daycare enrollment, days per week in daycare); and distal environmental influences: income/resources factors (family income, personal resources and social resources); and community factors (perceived child-rearing environment). The outcome variable was questionable development. Results: Significant contributors to questionable development in the infancy group were age, family health conditions, and personal resources; in the early childhood group, significant contributors were gender, family health conditions, grandparent as a primary caregiver, child-caregiver relationships, daycare enrollment, and personal resources. Conclusion: Factors influencing children's questionable development may vary by developmental stage. It is important to consider differences in individual and environmental influences when developing targeted interventions to ensure that children attain their optimal developmental goals at each developmental stage. Understanding this may lead nursing professionals to design more effective preventive interventions for low-income children.

This study was undertaken to obtain the data for age determination following the calcification degree of the third molar in the point of forensic odontology. The orthopantomograms of 1399 male and 2517 female ranging from 7 to 22 years of age were studied. The developmental state of the third molar was divided into 12 stages following the calcification degree and the mean ages of stage was obtained and statistically analyzed. The results were as follows : 1. There was remarkable correlation between the development of the third molar and age. 2. There was no significant developmental difference between the right and left third molar. 3. The development of the third molar presents difference between the male and female in the crown formation stages, but it was retarded in female than male in the root formation stages. 4. At the age under 20 years, we can determine the age within the range of * 2 years by means of orthopantomogram.

This paper investigated children's learning process concerning age and gender, two of the most apparent social roles. The subjects of the study were 72 Korean preschool children between three to five years of age. The Study was designed to examine problems of developmental sequence and horizontal decalage in understanding of these social roles. Two five-step knowledge sequences of age growth and sex constancy were administered utilizing skill theory (Fischer, 1980). Each step in a sequence had different stories of age or sex role with increasing cognitive complexity, but the two sequences were equivalent in complexity. The children were tested under two different assessment conditions:high support condition of elicited imitation and low support condition of free play and the best story. The findings show that, the understanding of age and sex roles develops through the predicted five-step sequences. The understanding of age role seems to develop earlier than that of sex role although the developmental patterns of the two roles are similar. Variations in the children's performances under different conditions were dramatic, especially for the older children.

It is widely assumed that Intelligence Quotient (IQ) is determined by inherent disposition and environmental factor. IQ is estimated by age-conversion score and stabilized around age 4 and IQ of adult age can be predicted after age 10. Though children with Mental Retardation (MR) are delayed in language development since early infant period, they receive only special education including speech and language therapy, but no special medication. In traditional Korean medicine, the etiology and treatment for developmental delay of language have been handed down for a long time. Some studies on herbs and prescriptions for improving language development have been undertaken recently. We have found several cases of significant elevation of IQ in the children treated with long term medications of Korean herbal medicine for improvement of language. Analyzing these cases, especially performance IQ showed significant change. Therefore we suggest that Korean herbal medicine might improve cognition development in children with MR.

Different aspects of morality, namely, moral belief, moral judgement and moral behavior have been studied seperately. This study examined the development of these three aspects of morality in relation to internal attribution in one sample. A total of 371, third -and sixth- grade children from Masan city were responded to questionnaires on moral belief, moral judgement, and attibutional tendency. In addition, children's moral behavior was measured by the teachers' 5-item rating scale. As results, there were signigicant but low correlations among three components of morality. There were developmental differences in moral belief and moral judgement but there was no age difference in moral behavior. Compared to third graders, sixth graders were higher in moral judgement but lower in moral belief. Social experience as well as cognitive development on moral relativity could explain this paradoxical developmental trend in moral belief. There was a sex difference only on moral behavior : Girls were rated higher in moral behavior than boys. Internal attribution was significantly correlated with all three aspects of morality, .15 with moral belief, .45 with moral judgement, .14 with moral behavior, respectively. There was a significant developmental difference but no sex difference in attributional tendency: Sixth graders reported higher internal attribution than third graders. However, there was no developmental difference in correlations among internal attribution and three aspects of morality. Most importantly, internal attribution explained morality better than either age -or sex- variable. It was suggested that educational programs on morality need to focus on the internalization of it.
