The purpose of this study was to examine the interaction strategies used by typically developing boys and girls in their dealings with young children with ADHD in free play situations in inclusive classes. This was done in order to gain an in-depth understanding of the meaning of their interaction strategies. The subjects were 52 typically developing children (comprising 27 boys, 25 girls) and 3 young children with ADHD. The findings were as follows : First, the overall frequency of interaction strategies with the young children with ADHD was greater among the young female children (n = 372) than the young male children (n = 298). Second, when the utterance strategies of the male and female children were sub-categorized, both the male children (79.5%) and the female children (57.0%) mostly made use of avoidance strategies, one of the typical withdrawal strategies. Third, the interaction strategy of control represented 42.0 percent and as such was identified as the most prevalent interaction strategy utilized by the young male children studied. In the case of the young female children, obliging strategies were the most common interaction strategies representing 33.1 percent of the total used. In the light of the findings yielded from this study, some educational recommendations are provided.

Background and Objectives: The Gaps-In-Noise (GIN) test is a clinically effective measure of the integrity of the central auditory nervous system. The GIN procedure can be applied to a pediatric population above 7 years of age. The present study conducted the GIN test to compare the abilities of auditory temporal resolution among typically developing children, children with speech sound disorder (SSD), and children with cognitive difficulty (CD). Subjects and Methods: Children aged 8 to 11 years-(total n=30) participated in this study. There were 10 children in each of the following three groups: typically developing children, children with SSD, and children with CD. The Urimal Test of Articulation and Phonology was conducted as a clinical assessment of the children's articulation and phonology. The Korean version of the Wechsler Intelligence Scale for Children-III (K-WISC-III) was administered as a screening test for general cognitive function. According to the procedure of Musiek, the pre-recorded stimuli of the GIN test were presented at 50 dB SL. The results were scored by the approximated threshold and the overall percent correct score (%). Results: All the typically developing children had normal auditory temporal resolution based on the clinical cutoff criteria of the GIN test. The children with SSD or CD had significantly reduced gap detection performance compared to age-matched typically developing children. The children's intelligence score measured by the K-WISC-III test explained 37% of the variance in the percent-correct score. Conclusions: Children with SSD or CD exhibited poorer ability to resolve rapid temporal acoustic cues over time compared to the age-matched typically developing children. The ability to detect a brief temporal gap embedded in a stimulus may be related to the general cognitive ability or phonological processing.

Denasalization that nasals are replaced by stops is an unusual error pattern related to manner of articulation. The purpose of this study is to investigate the prevalence of denasalization and to scrutinize the nasal production according to phonological context for typically developing children and children with speech sound disorders(SSD). 220 typically developing children and 48 SSD children from 2~6 years of age were tested with a formal word test, and those who demonstrate denasalization were selected. In addition, the nasal production of SSD children with denasalization were analyzed for the correctness and the error types using the formal word test and spontaneous conversation. The results were as follows: (1) Denasalization was shown in below 10% of 2-3 years of age with typically developing children and in above 20% of 2-5 years of age with SSD. (2) The SSD children who demonstrate denasalization were categorized into 4 types according to the error context of nasals; nasal errors with all word positions, nasal errors with word-final and word-medial positions, nasal errors with word-medial position preceding vowels, and nasal errors with word-medial position preceding obstruents. These results indicate that denasalization is a clinically important error pattern, and word-medial position preceding obstruents is an essential context for denasalization in terms of Korean phonotactics.

This study aimed to identify the development pattern of final stop consonant perception using the gating task. Sixty-four subjects participated in the study: 16 children aged 4 years, 16 children aged 5 years, 17 children aged 6 years, and 15 adults. One-syllable words with consonant-vowel-consonant(CVC) structure, mokㄱ-motㄱ and papㄱ-patㄱ were used as stimuli in order to remove the redundancy of acoustic cues in stimulus words, 40ms-length (-40ms) and 60ms-length (-60ms) from the entire duration of the final consonant were deleted. Three conditions (the whole word segment, -40ms, -60ms) were used for this speech perception experiment. 48 tokens (4 stimuli ${\times}3$ conditions ${\times}4$ trials) in total were provided for participants. The results indicated that 5 and 6 year olds showed final consonant perception similar to adults in stimuli, papㄱ-patㄱ and only the 6-year-old children showed perception similar to adults in stimuli, 'mokㄱ-motㄱ. The results suggested that younger typically developing children require more acoustic information to accurately perceive final consonants than older children and adults. Final consonant perception ability may become adult-like around 6 years old. The study provides fundamental data on the development pattern of speech perception in normal developing children, which can be used to compare to those of children with communication disorders.

Purpose: This study aimed to enhance health management and prevention strategies for precocious puberty by comparing the knowledge, motivation, and behaviors related to reducing exposure to endocrine disrupting chemicals (EDCs) between mothers of children with precocious puberty and those of typically developing children. Methods: Participants were 66 mothers of children with precocious puberty from a hospital and 71 mothers of typically developing children from an elementary school. The research questionnaire assessed knowledge of EDCs, motivation, self-efficacy, and behaviors towards reduced exposure to EDCs, in addition to general characteristics of children with precocious puberty. Data analysis utilized descriptive statistics, chi-square tests, t-tests, ANOVA, and Pearson's correlation. Results: There were statistically significant differences in self-efficacy (p=.015) and behavior (p=.001) regarding reduced exposure to EDCs between the two groups. Behaviors toward reduced exposure to EDCs were positively associated with knowledge of EDCs, motivation, and self-efficacy among mothers of children with precocious puberty. Additionally, these behaviors correlated positively with knowledge of EDCs, motivation, self-efficacy, and the child's birth weight and waist circumference among mothers of typically developing children. Conclusion: The results of this study revealed that mothers of children with precocious puberty exhibited less proactive behavior in reducing exposure to EDCs compared to mothers of typical children. Therefore, it is important to foster interest in the impact of environmental factors, beyond characteristic factors, on behaviors aimed at reducing exposure to EDCs.

The purpose of this study was to identify the characteristics of the phonological discrimination ability and phonological working memory of 10 typically developing children aged 4, and 10 other children with Specific Language Impairments whose language age is similar. In orders to compare their phonological discrimination ability among phonological awareness, discrimination tasks were conducted at the syllable and phoneme levels. Also, in order to compare their phonological working memory, the subjects repeated nonsense syllables. The research results may be summarized as follows: First, the children with Specific Language Impairments demonstrated a lower performance than the typically developing children in phonological discrimination ability at both syllable and phoneme levels, and the difference between the groups was statistically significant. Second, the children with Specific Language Impairments exhibited a lower phonological working memory performance in all syllables compared with normal children. Although there was no significant difference in 2 and 3 syllables, a significant difference appeared as the length of the syllables became longer from 4 to 6 syllables. It is deemed necessary to conduct research into qualitative and quantitative differences through an formal assessment of the phonological awareness and phonological working memory of children with Specific Language Impairments.

The purpose of this study was to investigate the differences of feeding ability and articulatory function in the children with spastic cerebral palsy and typically developing children according to feeding subtypes. The feeding subtypes were limited by chewing, cup drinking and spoon feeding. 14 children with spastic cerebral palsy and 14 typically developing children were participated in this study. The results were following as; First, there were significant differences in overall articulatory function between two groups Second, all scores of articulators' function according to feeding subtypes in children with cerebral palsy was significantly higher than typically developing children Third, chewing mode in feeding subtypes was highly correlated with lip and tongue movement. compared to another Finally, the correlation between spoon feeding and mobility of lip and tongue was high in both groups. These results suggested that These results suggest that the effort to find out the differences feeding ability and appliances for articulatory function in CP children are meaningful in catching their speech ability indirectly. Moreover, the more organized feeding skills should be discussed in the relationship with verbal and nonverbal development.

The purpose of this study is to compare the complexity of language level between verbally-precocious and typically-developing children from 2 to 3 years-old. Participants were 15 children classified as verbally-precocious were scored at the mean 56.85(expressive language) and 88.82(receptive language), and another 15 children classified as typically developing did at the mean 33.51(expressive language) and 58.01(receptive language) on MCDI-K. Each child's spontaneous utterances in interaction with her caregiver were collected at three different times with 6 months interval. All of the utterances were transcribed and analyzed for the use of MLU and lexical diversity by using KCLA. Summarizing the overall results, verbally-precocious children had significantly higher language abilities than typically-developing children at each time, and there were significant differences between two groups in syntactic and semantic language development, showing that verbally-precocious children indicated distinctive MLU and lexical diversity. These results suggest a high degree of stability in precocious verbal status, with variations in language complexity during conversations contributing to later differences in their language ability.

The current study examines PCC (percentage of correct consonant), speech intelligibility, and oral motor function between the group of typically developing children and the group of children with Down's syndrome. To 15 children with Down's syndrome (mean CA: 9;7) and 15 typically developing children on receptive language age, the following tests were administered: K-WPPSI (2001), Picture Vocabulary Test (Kim et al., 1995), Oral and Speech Motor Control Protocol for total oral functional score (Robbins et al., 1987), DDK and Assessment of Phonology and Articulation for Children (APAC, Kim et al., 2007) for PCC and speech intelligibility. Pearson correlation coefficients were computed for the total oral functional score, PCC and DDK of each group. The statistical analysis showed that there is no significant difference in total functional score and DDK when IQ was controlled. There was a significant correlation between total oral functional score and PCC in the Down's syndrome group and a significant correlation between total oral functional score and intelligibility in the Down's syndrome group whether IQ was controlled or not. The findings suggest that both cognitive ability and overall oral motor function need to be considered for the intervention to enhance PCC or speech intelligibility of children with Down's syndrome.
