The purpose of this study is to investigate the comprehension and production of various tense markings in Korean-speaking children with and without language delay. Thirty children with language delay(LD) and 30 typically developing(TD) children participated in the study. In each group, half were at the age of 4-years and the other half at 7-years. In both the comprehension and production task, 28 verbs containing four types of tense markings were used: past tense '-et ta', two present progressives '-ko itta', '-enta', and future tense '-elyeko hanta'. In the comprehension task, the children were presented with three printed still-scenes of video recording of a verb action, each representing future, present progressive, and past tense of the verb, respectively. Then they listened to the action verb with one of the 4 tense markings and had to pick the scene that matched the verb tense. In the production task, the children were given one of the three scenes and asked to produce the verb with appropriate tense marking. In both tasks, the LD children performed significantly worse than the TD children, and the older children performed significantly better than the younger children. Interestingly, the pattern of performances across different types of tense markings at the two language-age levels were closely similar in LD children and TD children. This similarity of groups seemed stronger in the comprehension task than the production task.

Purpose: This study examines changes in developmental profiles of children with language delay over time and the clinical significance of assessment conducted at age 2-3 years. Methods: We retrospectively reviewed the medical records of 70 children (62 male, 8 female), who had visited the hospital because of delayed language development at 2-3 years, and were reassessed at ages 5-6. Language and cognitive abilities were assessed using multiple scales at the initial and follow-up visits. Results: At the initial test, 62 of the 70 children had mental development index (MDI) below 70 of Bayley Scales of Infant Development Test II. Of the 62 children in the follow-up assessment, 30 children (48.4%) remained within the same cognitive range (full-scale intelligence quotient, FSIQ<70 of Wechsler preschool and primary scale of intelligence), 12 had borderline intellectual functioning (FSIQ, 70-85), 6 improved to average intellectual functioning (FSIQ>85), and 5 had specific language impairment, 9 had autism spectrum disorders. At the initial test, 38 of the 70 children had cognitive developmental quotients (C-DQ) below 70. Of the 38 children in the follow-up assessment, 23 children (60.5%) remained within the same cognitive range (FSIQ<70). The correlation coefficient for MDI and FSIQ was 0.530 (P<0.0001) and that for C-DQ and FSIQ was 0.727 (P<0.0001). There was a strong correlation between C-DQ and FSIQ, and a moderate correlation between MDI and FSIQ. Conclusion: Low MDI scores reflect a specific delay in cognitive abilities, communication skills, or both. The C-DQ, receptive language development quotient, and social maturity quotient also help to distinguish between children with isolated language delay and children with cooccurring cognitive impairment. Moreover, changes in the developmental profile during preschool years are not unusual in children with language delay. Follow-up reassessments prior to the start of school are required for a more accurate diagnosis and intervention.

Objectives Taking detailed patient history helps earlier diagnosis and treatment of developmental disability. In this study we analyzed the clinical questionnaire to find out the clinical characteristics of those with five-retardation, five-limpness, or five-stiffness. Methods The data was collected from 484 children under the age of six who have visited H oriental medicine clinic for developmental delay. The clinical questionnaire was filled out by their parents and the data was analyzed statistically. Results 436 children showed symptoms of five-retardation, 90 children suffered from five-stiffness, 54 children showed five-limpness and 7 children suffered from five-stiffness and five-limpness complex. Generally, boys had higher chance to show disease symptoms than the girls (2.32:1) and 40 children (8.26%) reported family history of developmental disability. Cerebral palsy ranks the most common familial disease, followed by developmental delay, mental retardation, autistic disorder and language disorder. Among the children we have studied, 285 children (63.19%) showed delayed unassisted walk while 192 children (42.57%) had language disorder. Also, 138 children (28.51%) had both walk and language disorders. The children in this study also showed delayed toilet training and half of them had little stranger anxiety when they were infants. It was also found that 120 children (24.79%) experienced epilepsy. This study reaffirmed that low birth weight, premature birth, and suffocation are major risks causing neurological damage. Conclusions They had history which including family history, problems at birth, epilepsy, face recognition, muscle tone disorder, delayed walking without assistance, language ability, and toilet training.

The purpose of this paper is to compare the two different instruction methods for Korean learners of academic purposes in learning request expression. Participants were divided into two groups, explicit and implicit group. Both groups viewed several scenes from the drama that involved native speakers interacting in different situations. The instructional treatment for the explicit group included metapragmatic information while the treatment for the implicit group did not. On the other hand, the treatment for the implicit group followed implicit techniques, which were repetition of the video presentation and a script reading activity. This study was made up of a pre-test, a post-test, and a delayed-test. The pre-test was conducted prior to the instructional treatment. The post-test was administered a day after the last instruction and the delayed-test was conducted five weeks after the treatments. Two types of tests, speaking and writing, were used in this study to examine subjects' knowledge of Korean request. The result of this research reveals that implicit treatment was more effective than explicit treatment in Korean learners' request acquisition. This results might have been due to the operationalization of the implicit condition in this study. Implicit instruction may help language learners make rules by themselves through tasks.

Relationships between immigrant mothers' Korean language ability and preschoolers' language development in multi-cultural families were studied with 91 mothers and their children. Language capacity of mothers and children was measured by receptive and expressive vocabulary test, sentence comprehension test and two kinds of reading tests. Results showed that mothers' level of comprehension was relatively low but their reading ability was higher than that of elementary school first-grade Korean students. Comprehension of children in multi-cultural families with non-immigrant counterparts showed a lower level of language ability. Mother's level of expressive vocabulary, receptive vocabulary and reading ability correlated with children's language development. These results indicate a relationship between children's delayed language development in multi-cultural families and mother's low proficiency in Korean language.

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.

It is widely assumed that Intelligence Quotient (IQ) is determined by inherent disposition and environmental factor. IQ is estimated by age-conversion score and stabilized around age 4 and IQ of adult age can be predicted after age 10. Though children with Mental Retardation (MR) are delayed in language development since early infant period, they receive only special education including speech and language therapy, but no special medication. In traditional Korean medicine, the etiology and treatment for developmental delay of language have been handed down for a long time. Some studies on herbs and prescriptions for improving language development have been undertaken recently. We have found several cases of significant elevation of IQ in the children treated with long term medications of Korean herbal medicine for improvement of language. Analyzing these cases, especially performance IQ showed significant change. Therefore we suggest that Korean herbal medicine might improve cognition development in children with MR.
