Objectives : The objective of this study was to evaluate the relationship of the parenting stress with their children's characteristics for typically developing preschool children. Methods : Parents of 38 preschool children (mean age : 4.4${\pm}$0.7 years, 22 boys) completed the Korean Parenting Stress Index, the Korean Child Behavior Checklist, the Conners Parent and Teacher Rating Scale-Abbreviated form (CPRS and CTRS), the Junior Temperament and Character Inventory, the Children's Sleep Habit Questionnaire and the Social Responsiveness Scale. All 38 children performed the Comprehensive Attention Test (CAT). Results : The children's inattentive and hyperactive problems, as measured by the CBCL, CPRS and CAT, had positive correlation with parenting stress. Both internalizing and externalizing behavioral problems were associated with parenting stress. Of the child's temperament dimensions, Novelty Seeking and Harm Avoidance were positively correlated with parenting stress, but Persistence and Cooperativeness were negatively correlated with parenting stress. Sleep anxiety and other sleep characteristics showed a correlation with parenting stress. Social Motivation and Communication were also positively related to parenting stress. Conclusion : Our results suggest that parenting stress could be related to the children's cognition, emotion, behavioral characteristics, sleep habits and social development. These results could assist in the development of interventions to improve the parental well-being in typically developing preschool children.

Objective : The objective of this study was to determine a discriminat validity of the Sensory Processing Scale-Children (SPS-C) for children with and without Sensory Processing Disorder (SPD). Method : The SPS-C was completed by parents of 151 Korean children including 68 typically developing children (control group), 83 children with SPD (known group) in the age range 3-5 years, in South Korea. ANCOVA with sex as covariable was used to identified the difference between the children with typically development and SPD. Results : Sensory processing differences in sensory domains and sensory factors were detected and the gender differences were not effective between typically developing children and children with SPD. Significant differences were found in all sensory domain score and total score except proprioceptive processing in sensory domain. In sensory factors, significant differences were found in overrsensitivity, underresponsivity, and discrimination, but sensory seeking was not significant. SPS-C was a valid assessment tool to identify or screen of SPD in Korea. Conclusion : The psychometric characteristics for the standardization study of SPS-C were presented, and the discriminant validity to screen the children with sensory processing problems was presented as a verified evaluation tool. SPS-C will be helpful in screening, analyzing and interpreting characteristics of sensory processing, and establishing an intervention plan.

Objective : The purpose of this study was to compare the effects of the sensory processing characteristics of parents of developmentally delayed children and parents of typically developed children on parenting stress. Methods : From July to August 2022, 61 parents of children with developmental delays and 64 parents of children with typical development who used occupational therapy services at pediatric clinics and child development centers were evaluated for parenting stress and sensory profiles. Results : In a multiple regression analysis on the effect of sensory processing characteristics on the total score of parenting stress, tactile processing (β = 0.353, p = 0.001), gender (β = 0.438, p = 0.000), and monthly income (β = -0.261, p = 0.014) significantly affected the parenting stress of the parents of children with developmental delay. In parents of typically developing children, tactile processing (β = 0.376, p = 0.002) and gender (β = -0.264, p = 0.024) were found to have a significant effect on parenting stress. Conclusion : Parental gender and tactile processing characteristics of developmentally delayed and typically developing children are significant influencing factors for parenting stress.

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 the study was to examine alternating motion rate and its variability in children with childhood apraxia of speech (CAS) compared to typically developing children. Six children with CAS aged 9-12 years old and 10 children who were age-matched participated in the study. This study measured tokens per second and variabilities of the rates during the production of /$p^*$ a/, /$t^*$ a/, and /$k^*$ a/. For variability measures of the rates, each participant was asked to repeat speech tasks three times and the average value of the rates and its standard deviation were obtained. The results revealed that the CAS group showed slower rate only at /$k^*$ a/ than the control group. The CAS group exhibited greater variability of AMR at all the tasks than the control group. The results suggested that variability of AMR might be a more distinctive speech feature to children with CAS than the rate of the speech task.

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 this study was to investigate whether young children with cleft palate differ from those of noncleft typically developing children in terms of expressive vocabulary size, phonological characteristics and lexical selectivity. A total of 12 children with cleft palate and 12 noncleft children who were matched by age and gender participated in the study. The groups were compared by size of expressive vocabulary reported on Korean version of MacArthur-Bates Communicative Development Inventories and the number of different words, consonant inventory, the percentage of words beginning with obstruents and vowels, nasal, and glottal sounds, and the percentage of words which do not include obstruents in a language sample. Also, correlation analysis were performed to examine the relationship between measures on size of expressive vocabulary and phonological characteristics. The results showed that expressive vocabulary size and consonant inventory for children with cleft palate produced significantly smaller than those for noncleft children. Children with cleft palate produced significantly more words beginning with vowel or which do not include obstruents, and fewer words beginning with obstruents than noncleft children. The two groups showed different results on significant correlations between measures on size of expressive vocabulary and phonological characteristics indicating that children with cleft palate show different lexical selectivity from their noncleft peers. The results suggest that children with cleft palate aged 18-30 months demonstrate a slower rate of lexical and phonological development compared with their noncleft peers and they develop lexical selectivity reflecting cleft palate speech. The results will have a clinical implication on speech-language intervention for young children with cleft palates.

Eater Seal, the child care experts, observes that children with disability significantly benefit from receiving appropriated care along side their peers. Typically developing children serve as role models from which children with disabilities learn age-appropriated communications and social behavior. Therefore the children with disability can actively participate in well-designed child care settings. But unfortunately in Seoul, Korea, only 2% of children with disability are taken care of in child care centers. And even the disabled children at the child care centers are mostly mentally or emotionally disabled because the building, programs and services of the centers are restrictive to the children with severe physical disabilities. This study reviewed Korean domestic physical environment of child care centers for children with disabilities. Questionnaire survey was conducted to 103 centers located in Seoul by mail. Our survey revealed that they need more areas for nursing room and special rooms and the accessibility to buildings has to be improved. Also, there are no elevators in all buildings surveyed. Accessibility to toilet is noted as significant problem, especially wet floors in toilets. In a nursing room, a space for psychological rest and special education is needed for children with mental disability. Technical specifications on how to make buildings and facilities accessible for the children with disability should be developed. The goal of this study is to provide basic information to develop domestic design guidelines to ensure that the child care centers are safe, convenient, and usable for everyone possible.

This study reviewed Korean domestic physical environment of child care centers for children with disabilities. 15 centers located in Seoul were surveyed. Our survey revealed that the accessibility to buildings is poor. There are many places with difference in height of floors. Also, there are no elevators in all buildings surveyed. Accessibility to toilet is noted as significant problem, especially wet floors in toilets. In a nursing room, a space for psychological rest and special education is needed for children with mental disability.

This study aims to compare the performance of syllable identification task according to auditory and visual stimuli presentation methods and syllable position. Twenty-two typically developing children (age 4-6) participated in the study. Three-syllable words were used to identify the first syllable and the final syllable in each word with auditory and visual stimuli. For the auditory stimuli presentation, the researcher presented the test word only with oral speech. For the visual stimuli presentation, the test words were presented as a picture, and asked each child to choose appropriate pictures for the task. The results showed that when tasks were presented visually, the performances of phonological awareness were significantly higher than in presenting with auditory stimuli. Also, the performances of the first syllable identification were significantly higher than those of the last syllable identification. When phonological awareness task are presented by auditory stimuli, it is necessary to go through all the steps of the speech production process. Therefore, the phonological awareness performance by auditory stimuli may be low due to the weakness of the other stages in the speech production process. When phonological awareness tasks are presented using visual picture stimuli, it can be performed directly at the phonological representation stage without going through the peripheral auditory processing, phonological recognition, and motor programming. This study suggests that phonological awareness skills can be different depending on the methods of stimulus presentation and syllable position of the tasks. The comparison of performances between visual and auditory stimulus tasks will help identify where children may show weakness and vulnerability in speech production process.
