The human baby appears to be born with preexistent knowledge of language. This specialized neural structure in the brain awaits auditory experience with language to trigger it into functioning. The auditory-linked acquisition of language is a time-locked function related to early maturational periods in the infant's life. The longer auditory language stimulation is delayed, the less efficient the language facility will be. It is for these reasons that it is urgent to fight the hearing problems of children with all the skill, knowledge and insights of which we are capable, the so called 'rehabilitative process'. An understanding of the timetable and the origin of prenatal to early life development of auditory mechanism will help in planning the aural rehabilitation. Further interests and studies are needed to establish the systematic structure of rehabilitative audiology.

The Korean Metaphonological Assessment, adapted from the Metaphonological Abilities Battery (MAB; Hesketh, 2000b) was administered to examine the development of metaphonological skills of 60 normally developing Korean pre-school children aged from 3 to 6. The tasks were specifically designed to evaluate their skills to detect rhymes, onsets, and segments. A gradual improvement of total scores was observed in children from 3 to 5, with evidence for developmental refinements of metaphonological abilities in the ages of 5 and 6. Subjects were found to develop segmenting skills at a relatively early age and gradually progressed toward detecting onsets and then rhymes. The differences in the order of development from the previous studies with English-speaking children were discussed. This preliminary study also aimed to provide foundational information for investigating the link between expressive phonological impairments, metaphonolgocial skills, and literacy in Korean-speaking children.

In this paper, correlation analysis between speech characteristics and the dose of antipsychotic drugs was performed. To investigate the pattern of speech characteristics of ExtraPyramidal Symptoms (EPS) related to voice change, a common side effect of antipsychotic drugs, a Korean-based extrapyramidal symptom speech corpus was constructed through the sentence development. Through this, speech patterns of EPS and non-EPS groups were investigated, and in particular, a strong speech feature correlation was shown in the EPS group. In addition, it was confirmed that the type of speech sentence affects the speech feature pattern, and these results suggest the possibility of early detection of antipsychotics-induced EPS based on the speech features.

Hearing loss is the most common birth defect among infants. Yet most hearing-impaired children are not identified until 1 to 3 years of age - which is well beyond the critical period(6 month) for healthy speech and language development. However, if a hearing-impairment is identified and treated in its early stages, child's speech and language skills will be comparable to his or her normal- hearing peers. For these reasons, hearing screening at birth and routinely throughout childhood is extremely important. Auditory brain-stem response(ABR) is nowadays one of the most reliable diagnostic tools in the early detection of hard of hearing. In this study, we developed the system that detects auditory evoked potential using micro-processor. Furthermore, it is required to develop a portable system to measure in not only soundproof room but also nursery for infants.

This paper proposes interactive game elements for children : contents, design, sound, gesture recognition, and speech recognition. Interactive games for early children must use the contents which reflect the educational needs and the design elements which are all bright, friendly, and simple to use. Also the games should consider the background music which is familiar with children and the narration which make easy to play the games. In gesture recognition and speech recognition, the interactive games must use gesture and voice data which hits to the age of the game user. Also, this paper introduces the development process for the interactive skipping game and applies the child-oriented contents, gestures, and voices to the game.

This study explores reading fluency among elementary school students considering language level and family income(low SES). Forty eight students from 1st to 3rd grades participated in two paragraph reading tasks. Half of the children were from low income family and half of the children had low lexical knowledge. Reading fluency as in the number of correctly read syllables per minute, the total error frequency and error types were used to compare group differences. There were significant differences in the number of correctly read syllables per minute between two income groups and two language groups. There was a significant difference between low income group and non-low income group in total number of errors only when children's lexical knowledge were low. There were no group differences in error types of repetition and omission. Substitution and insertion error seemed to reflect the total error pattern. These results imply the importance of early screening and early involvement for children with low lexical knowledge from low income family. Monitoring and early intervention will support these children's reading development.

This study investigated relationships between engagement in joint attention and the early language development in infancy. Subjects were 12 infants and their mothers. At 20 and 25 months of age, each child's spontaneous natural speech during interaction with his/her caregiver was videotaped for about 30 minutes. The EJA(Episodes of joint attention) focus between mother and child were identified and coded by Tomasello and Todd's(1983) and Bakeman and Adamson's(1984) including person engagement, object engagement, looking engagement, passive joint attention, coordinated joint attention. Results showed that a significant difference in infant's language development between within and outside EJA at 20 and 25 months of age; that is, during periods of EJA children talked more inside than outside EJA.

Hearing loss is one of the most common birth defects among infants. Most hearing-impaired children are not diagnosed until one to three years of age, which is too late to treat for normal speech and language development. If a hearing impairment is identified and treated in its early stage, child's speech and language skills could be comparable to his or her normal-hearing peers. In this study, we applied the 'Fsp' method to distinguish between normal and impaired hearing. We have developed a battery-operated portable A - ABR(automated auditory brain stem response) system that automatically detects hearing impairment for neonates or infants in a nursery room, as well as in a sound-proof room. We partially validated the accuracy of the system in five normal-hearing adults.

Purpose: The purpose of this study was to look for physical growth and developmental retardation of the disabled children in registered educational institutions. Method: The participants in this study were 103 children. The data was collected from January to September 2006. Body weight, height and head circumference were measured and the Denver II developmental screening tool was used to measure personal-social development. Results: For 40.8% of the children body weight was less than the average for Korean children of the same age, for 49.5% height was lower than average and for 44.7% head circumference was lower. For 84.5% of the children there was a delay in personal-social development, for 87.4% a delay in fine motor-adaptive development, for 80.6% a delay in speech development and for 81.6% a delay in gross motor development. Conclusion: Based on the findings of this study, it is necessary to develop an individual developmental programs for these children based on their growth and development status.

The research mainly focused on how the nasagastric tube used to solve feeding troubles developed by 30 children with CP(Cerebral Palsy) affects the post-childhood feeding development right after their birth. It tested an articulation skill of the children and surveyed their feeding ability with their care-givers from 1st in July to 30th in August, 2015. This study conducted an investigation of the way a feeding ability affects an articulation skill. It suggested that an articulation accuracy significantly depends on whether or not the nasagastric tube is used. Also, the findings showed that the post-articulation accuracy is quite related with the problems for the liquid intake, the use of special feeding methods and tools, and biting and chewing among the evaluating problems for the childhood feeding ability. The research concluded that some areas in the early childhood feeding ability have an apparent influence on the post-articulation skill for children with CP.
