The purpose of this research was to find out how the interactions between mothers and their children differed depending on the age of the child and the type of book. The subjects of this study were thirty 2-year-olds and thirty 4-year-olds and their mothers. The number of male and female children was the same. The maternal interactions were analyzed in term of attention gelling, explanation, request, asking questions, and feedbacks, and the children's verbal and nonverbal reactions were also analyzed. The results showed that the characteristics of the mother and child interactions were different according the age of the child and the type of picture books. The results were discussed from the perspective of maternal scaffolding and the quality of mother-child interactions. The implications of the study were suggested in terms of the importance of the picture books and maternal roles in reading pictures books to their child.

This study investigated preschoolers' happiness, behavior problems, and interpersonal problem solving strategies according to their sex and age, and the relationships among them. The subjects were 185 preschoolers (97 boys and 88 girls; 83 four-year-olds and 102 five-year-olds). Results showed that boys were higher in behavior problems (aggression) and forceful problem solving strategies than girls, while girls were higher in happiness (characteristics of self) than boys. Also, 4-year-old children were higher in forceful problem solving strategies than 5-year-olds. Children's happiness was negatively related to their internalizing and externalizing behavior problems. Behavior problems and interpersonal problem solving strategies of children were influenced by their happiness. These findings provide preliminary evidence that children's happiness may predict their behavior problems and interpersonal problem solving strategies.

Objectives: Bisphenol A (BPA) is used in the electrical, mechanical, medical, and food industries. Previous studies have suggested that BPA is an endocrine disruptor. Regulation of BPA has led to increased use of bisphenol F (BPF) and bisphenol S (BPS). However, few studies have investigated the associations of BPF and BPS with thyroid dysfunction in children. Our study investigated the associations of prenatal BPA and early childhood BPA, BPF, and BPS exposure with thyroid function in 6-year-old children. Methods: Prenatal BPA concentrations were measured during the second trimester of pregnancy in an established prospective birth cohort. We measured urinary BPA, BPF, and BPS concentrations and thyroid hormone levels (thyroid-stimulating hormone, total T3, and free T4) in 6-year-old children (n=574). We examined the associations between urinary bisphenol concentrations and percentage change of thyroid hormone concentrations using multivariate linear regression. We also compared thyroid hormone levels by dividing the cohort according to BPA, BPF, and BPS concentrations. Results: The associations between prenatal BPA and total T3 levels were statistically significant in all models, except for girls when using a crude model. The associations between urinary BPA and BPS concentrations and levels of all thyroid hormones were not statistically significant. However, we observed that lower free T4 levels (-1.94%; 95% confidence interval, -3.82 to -0.03) were associated with higher urinary BPF concentrations in girls only. Conclusions: Our findings identified significant associations between prenatal BPA exposure and total T3 levels in all children and between BPF exposure and free T4 levels in girls only.

The purpose of this study is to investigate prior thinking and posterior thinking formation of children and adolescents in sinking objects. The subjects consisted of twenty eight, 9- and 11-year old children and fourteen, 13-year old adolescents selected from one elementary school and two middle schools. The transcripts were analyzed to classify children and adolescents'prior thinking and posterior thinking frequency, reasoning response(evidence based response, idea based response) and reasoning method(valid method, invalid method). The data were analyzed by frequency, percentile, mean and standard deviation,1 test, ANOVA. Major findings were as followings: 1. Children and adolescents have already had prior thinking in sinking objects. 2. Children and adolescents applies their prior thinking to posterior thinking formation process. 3. There were significant differences in children and adolescent'posterior thinking formation process, especially choices in objects and reasoning methods depending on age. 4. There were significant differences in children and adolescents'reasoning response depending on presented evidences types.5. Through the experimentation, children and adolescents'prior thinking was different from their posterior thinking. There were significant differences in differences between the prior thinking and posterior thinking depending on age.

The purpose of this study was to verify preschool children can be classified of Attention-Deficit Hyperactivity Disorder (ADHD) children across situation. It also was to examine differences among groups according to sex and age, and to investigate the family caracterisitcs of ADHD groups. The subjects of this study consisted of 228 preschool chilren (147 boys and 136 girls aged from 3- to 7- year-old) drawn from five Child Care Centers in Chung-Ju. Data were analyzed by the frequency, percentages, Cronbach's ${\alpha}$ coefficient, ${\chi}^2$-test, F-test, Tukey post-hoc test, and Pearson correlation using SAS program. The results were as follows: 1. Preschool children could be classified by four diagnostic groups across situation; (1) 168 children (59%) of the control group (no disorder of ADHD), (2) 49 children (17%) of ADHD-Home group (ADHD only at home), (3) 43 children (15%) of ADHD-School group (ADHD only at school), and (4) 23 children (8%) of ADHD-PH group (ADHD both at home and at school). Ratings by parents and by teachers correlated very low with each other, as in previous studies. These results confirm the findings that ADHD be classified across situation. 2. There were significant differences among four groups according to sex and age. In the ADHD-PH groups, the boys is 3 times higher than the girls and the children aged 6- to 7-year-old was shown highly distributed in the pervasive ADHD.

Objective : Essential oil inhalation and He-Ne laser treatment has become increasingly available in children with nasal diseases. But the reports on the effect and prognosis have been poor. In this study, we analyzed the treatment effect, recurrence rate and the degree of recurrent symptoms. Materials/Methods: 23 children(2-10 year-old) with nasal diseases, who received essential oil inhalation with He-Ne laser treatment at least 10 times in our hospital from January 1st 2001 to December 31th 2002 were studied. Result : Ten cases are male & thirteen cases are female. The average of age was 4.91 year-old. The most frequency symptoms are nasal discharge (82.6%), nasal obstruction (78.3%), cough (47.8%), secretion sound (39.1%), sneezing (17.4%). Average numbers of treatment period, interval and treatment times are 71.79 days, 4.06 days, 18.13 times respectively. Of the 23 children, 14 children were in 'all symptom improved' at the remedial ends, and 22 children relapsed. In the degree of recurrent symptoms, 15 children were in 'more improved then before-treatment and not equal to directly remedial ends'. No case was in 'worse than before-treatment'. The final result of treatment, 6 children keep the degree of remedial ends, on the other hand 17 children are not. Conclusions : Even though, the recurrence rate was high, this combined treatment improve nasal symptoms. The final assessment is good, when the treatment-result is good, when the treatment interval is regular and when parent's are cooperative. If the symptoms continue a whole year, the result is not so good.

The purpose of this study was to examine the bidirectional relationship between the negative emotionality of 0-to 3-year-old and maternal parenting styles, focusing on warmth and reactivity. Four waves of panel data from the Korean Children Panel Study(KCPS) were analyzed in this study by means of autoregressive cross-lagged modeling. The results of this study were as follows. First, negative emotionality and maternal parenting styles were consistently stable for 0-to 3-year-old. Second, a bidirectional relationship between negative emotionality and maternal warmth parenting styles was confirmed according to the appearance of both parent and child effects. In other words, higher levels of negative emotionality was associated with lower maternal warmth parenting styles across time and in both directions. Additionally, the relationship between negative emotionality and maternal reactivity parenting styles were partially identified as being bidirectional in nature, whilst also being related to age. These findings suggested that parent education aimed at strengthening parenting skills, and programs designed to relieve negative emotionality of 0-to 3-year-olds are clearly needed.

Korean alveolar fricatives are late-developing speech sounds. Most previous research on phonemes used individual words or pseudo words to produce sounds, but word-level phonological analysis does not always reflect a child's practical articulation ability. Also, there has been limited research on articulation development looking at speech production by grammatical morphemes despite its importance in Korean language. Therefore, this research examines the articulation development and phonological patterns of the /s/ phoneme in terms of morphological types produced in children's spontaneous conversational speech. The subjects were twenty-two typically developing 3- and 4-year-old Koreans. All children showed normal levels in three screening tests: hearing, vocabulary, and articulation. Spontaneous conversational samples were recorded at the children's homes. The results are as follows. The error rates decreased with increasing age in all morphological contexts. Also, error percentages within an age group were significantly lower in lexical morphemes than in grammatical morphemes. The stopping of fricative sounds was the main error pattern in all morphological contexts and reduced as age increased. This research shows that articulation performance can differ significantly by morphological contexts. The present study provides data that can be used to identify the difficult context for articulatory evaluation and therapy of alveolar fricative sounds.

The purpose of the present study was to investigate children's interpersonal problem solving strategies. Specifically, the number and categories of interpersonal problem solving strategies were examined by age, sex, and source of problem (friends or mother). The subjects were eighty 4,-and 6-year-old boys and girls. The instrument was based on Shure and Spivack's (1974) Preschool Interpersonal Problem Solving (PIPS) test. The test was administered to the children individually in the preschool setting. The data were analyzed by two-way ANOVA, frequency, percentage, and Kendall's Tau. The results showed that the older children had higher PIPS scores; that is, the 6-year-olds suggested more alternative problem solving strategies than 4-year-olds. Children suggested more alternate strategies and different strategies for solving problems with friends compared to solving problems with mothers.
