The purpose of this study was to know the characteristics of DDK performance between CV(e.g. 'pa') and VV(e.g., 'ai') syllables in typically developing children aged 4 to 6 years old. 12 TD children performed DDK with CV structure(/pʰə/, /tʰə/, /kʰə/, /pʰətʰə/, /tʰəkʰə?/, /pʰətʰəkʰə/) and with VV structure(/ai/, /ɔi/, /ɑɔi/). Spoken syllables were counted in one second, and all spoken DDK were measured by PC-quirer. The results showed that all spoken DDK became faster as the age of children were increased. This trend was also appeared in both CV and VV syllables repetition. In addition, there was no differences in DDK rate with CV and VV syllables. The frequency of articulatory error during DDK performance was very high in the age of 3, and there was no pattern in the frequency of articulatory error according to the developmental age.

Objective : This paper aimed to measure the relationship between the performance of Korean handwriting and visual fixation for children. Methods : Twenty-one typically developing children aged 7 to 9 years participated in the study. The children performed Korean handwriting task wearing Tobii Pro Glasses 2. The Korean handwriting task consisted of 10 words from elementary school textbooks. The handwriting skill was measured by the coefficient variation of the letter size and the fixation cound and duration. Correlation analysis was performed to investigate the relation between visual fixation and the coefficient variation of the letter size. Results : The results showed that the visual fixation per second was positively correlated with Korean handwriting vertical size coefficient variation, indicating that the more consistent the vertical size of the letter, the smaller the fixation count per second. Conclusion : The results suggested a relation between the performance of Korean handwriting and visual fixation in typically developing children. This study is the first attempt to measure eye movement during the Korean handwriting process, and suggests a future direction for research on students' development in writing Korean.

This study aimed to investigate the acoustic characteristics of emotional speech in typically developing children. Thirteen preschoolers (4-5.9 years old) and 22 school-aged children (6-9.9 years old) participated in the study. The children were asked to imitate 15 utterances based on emotional utterances representing three different emotional expressions (happy, sad, and angry). Basic measures of the frequency, intensity, and duration of emotional expressions in the children's utterances were obtained as averages. We found that both preschoolers and school-aged children differentially imitated the emotional utterances in terms of basic frequency, intensity, and duration depending on the type of emotion (happy, sad, angry). In particular, we found that school-aged children spoke more slowly than preschoolers when expressing sadness. These results suggest that preschoolers and school-aged children can express emotions by modulating vocal pitch, intensity, and duration. In addition, school-aged children tended to modulate the duration parameter of prosodic elements to express different emotions compared to preschoolers. In general, differences in duration between developing children may be influenced by the maturity of the child's speech and language development.

Sensory integration started as a theory to provide a occupational therapist with a useful frame for explaining and intervening the problems which children have. Most researches on sensory processing disorder (SPD) have been found empirical evidence to support the sensory integration theory by measuring behavioral manifestations of SPD. Recently, researchers who are interested in the diagnosis of SPD have begun to use neurophysiological methods to establish objective evidence for sensory integration. These studies reported the neurophysiological indexes reflecting the maladaptive behaviors as well as the difference between children with SPD and typically developing children in using electrodermal activity, vagal tone, EEG. Future neurophysiological studies on SPD will be expected to prove the efficacy of sensory integration intervention.

Purpose: Impaired reaching movement is commonly observed in children with cerebral palsy. The purpose of this study was to determine whether the inclination of seat surface can influence the reaching movement in children with spastic diplegic cerebral palsy (CP). Methods: The subjects were 31 children, 16 children with spastic bilateral CP and 15 typically developing (TD) children. The children performed static sitting and forward reaching under three conditions: a horizontal seat surface (Horizontal $0^{\circ}$), a seat surface inclined anterior 15 degrees (Ant $15^{\circ}$), and a seat surface inclined posterior 15 degrees (Post $15^{\circ}$). A 3-axis accelerometer ('ZSTAR3') was used for analysis of the reaching movement. A 3-axis accelerometer was attached on the manubrium of the sternum, lateral epicondyle of the humerus, and styloid process of the ulna. We measured the reaction time, movement time, and data amount during reaching the 8 cm target with an index finger on the three inclined seat surfaces. Results: Reaction time and movement time for CPs showed significant delay; comparing the TD's and CP's amount was significantly greater than the TD's during reaching task (p<0.05). In particular, CP's reaction time and movement time on a seat surface inclined Ant $15^{\circ}$ was significantly more delayed compared with the other seat surfaces (p<0.05). Conclusion: Our results suggest that seat-inclination intervention may provide an ergonomic approach for children with spastic cerebral palsy.

Objectives : The objective of this study was to compare the Korean Personality Rating Scale for Children (K-PRC) profile between children with attention-deficit hyperactivity disorder (ADHD) and typically developing children. We also aimed to investigate the association of K-PRC and ADHD symptoms. Methods : Ninety-nine youth (age $8.3{\pm}2.4$ years, 72 boys) with ADHD and 84 controls (age $9.2{\pm}2.5$ years, 43 boys) were recruited from the Department of Pediatric Psychiatry of the Asan Medical Center Children's Hospital. Diagnoses of ADHD and comorbid psychiatric disorders were confirmed with the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL). The parents of the subjects completed the ADHD rating scale, and K-PRC. Independent t-tests, analysis of covariance, partial correlation analyses, and Mc Nemar test were used for analysis. Results : Children and adolescents with ADHD showed higher K-PRC scores in verbal development, physical development, depression, delinquency, hyperactivity, family dysfunction and psychoticism. Delinquency and hyperactivity were significantly correlated with parent-rated ADHD rating scales and ADHD scores on K-SADS-PL. The hyperactive/impulsive and combined subtypes showed higher scores on hyperactivity and delinquency than the inattentive subtype, and the inattentive subtype showed higher scores on depression and social dysfunction of the K-PRC. Conclusion : Our results suggest that K-PRC could be used to comprehensively evaluate symptoms, combined psychopathologies, developmental delay and family dysfunction of children with ADHD.

Objectives: This study aimed to analyze menu patterns and food group diversity in daycare centers managed by the Center for Children's Foodservice Management in South Korea. Methods: Data from 18 Center for Children's Foodservice Management centers across various provinces (excluding Jeju Island) were analyzed. We examined 8,796 meals served in February, May, August, and December 2021, focusing on seasonal lunch and snack menus for children aged 3-5. Foods were categorized into 19 groups for lunch and 21 for snacks. The frequency of food groups and dietary patterns were assessed using the Dietary Diversity Score. Analyses were conducted using Excel 2016 and IBM SPSS Statistics version 28. Results: Most lunch menus (89%) included five menu items, with a ratio of grain, meat, and vegetables at 88%. Snack menus typically had one item (57%), with significantly more items in the afternoon compared to the morning (P < 0.001). Regarding snack patterns, 75.2% of morning snacks and 61.1% of afternoon snacks contained only one solid food and drink (P < 0.001). Fruit and milk (22.4%) was the most prevalent pattern in morning snacks, while grain and milk (31%) dominated afternoon snacks (P < 0.001). Only 48% of daycare center menus (all snacks and lunch) included all five food groups (grain, meat, vegetables, fruit, and milk). Notably, only 83% included milk and 57% included fruit. Conclusions: These findings highlight the need to improve food variety and diversity in the Center for Children's Foodservice Management-managed daycare center menus. Developing more detailed guidelines for menu structure and food composition is crucial to ensure children receive balanced and diverse nutrition.

This paper aimed to find out the differences of DDK performances of 37 normally developing children in the range of 4-6 years. DDK tasks included with the Consonant-Vowel(CV) syllables and with the Vowel-Vowel(VV) syllables. For DDK rate, all spoken AMR and SMR in one second were measured by Multi-Speech, and analyzed with Motor Speech Profile for DDK regularity. Error frequency and type in DDK performance were transcribed and auditorily judged by two professional speech pathologists. The findings in this study were follow as: First, DDK rate became faster as the age of children were increased. But there were no statistical differences between the groups for age. Second, there was no significant differences the CV and VV syllables of DDK tasks. Third, the frequency of articulatory error in DDK performance was significantly higher in the age of 4 than other two groups.

Purpose: Feeding problems are common for typically developing children and have negative effects on physical, behavioral, and cognitive development. The purpose of the current study was to examine factors related to childhood feeding problems for typically developing children via parental reports. Methods: The feeding questionnaire developed by the authors and the Childhood Eating Behavior Inventory (CEBI) were administered to 796 parents of children who recruited from 2 pediatric outpatient clinics (n=379) and community (n=417). Problem eaters (PE) were identified by parental report and frequency analysis was conducted for types of feeding problems and its severity, problem behaviors during mealtime, the feeding methods of the parents, and the need for treatment. Results: The CEBI scores were significantly different between the PE and non-problem eaters (NPE), which suggests that the parental reports were reliable. The younger children had more feeding problems than the older children. The most frequent and severe feeding problems were selective eating and longer mealtimes across all age groups. One-half of the children had more than one problem behaviors during mealtime. Most parents of PE used ineffective methods to deal with children's behaviors during meal time, such as cajoling, which was related to their increased level of stress. Many parents reported their children need professional help for the feeding problems. Conclusion: Feeding problems are prevalent among children, especially younger children. Children with feeding problems showed a number of problem behaviors during mealtime and parental coping methods appeared to be ineffective. The need for treatment was considerable, thus the characteristics of this population must be acknowledged for providing proper treatment and advice.

Objective : The purpose of this study were to examine internal reliability and internal validity for Short Sensory Profile(SSP) and to suggest the useful criteria for sensory processing abilities in Korean culture. Methods : The Short Sensory Profile(SSP) was completed by mothers of 304 children typically developing between 3 to 10 years of age in those preschool, kindergarten and elementary school located Seoul and Gyeonggi-do. The total agency for this study was 14 facilities and the period of study was from July, 2002 to June, 2003. Kim Mi Sun(2001) translated and modified the Short Sensory Profile that Macintoshi developed and the tool for the study was used. The data were analyzed with reliability test and Pearson's correlation. Results : 1. Internal reliability of the total tests and sections was estimated by calculating Cronbach's Alphas. Reliability value of the total tests was .889. 2. For internal validity the correlations range from .131 to .575 in magnitude, suggesting that the sections of the Short Sensory Profile tap relatively unique constructs and support the factor structure developed. 3. The total score of the Short Sensory Profile(SSP) range from 118 to 190, mean and SD was 163.12, 14.87. 4. Of 403 children represented by the survey, 32 children(10.5%) met criteria for sensory processing disorders based upon parental perceptions. 5. Cut scores were determined by computing the raw score cut scores for -1 SD and -2 SD. The normal group of sensory processing abilities had score which range from 190 to 149, the probable problem group had score which range from 148 to 134, and the definite problem group had score which range from 133 to 138. Conclusion : Findings from the above study suggest that Short Sensory Profile be the screening tool for sensory processing disorders within Korean culture. Further research is needed to compare with children with the various sensory processing disabilities(PDD, LD, CP ect,).
