Phonological awareness is a metalinguistic awareness ability of phonology and is known to predict language skills, such as reading and vocabulary skills. The purpose of this study was to investigate the relationship between phonological awareness, phonological processing, and language skills in 4- to 6-years-old typically developing (TD) children and children with language delay (LD). A total of 32 children (TD=18, LD=15) participated in this study. They performed a phonological awareness task consisting of counting, deletion, and discrimination at syllable level. Nonword Repetition, Digit Backward, Receptive & Expressive Vocabulary Test, and Grammaticality Judgment Task were performed to analyze the correlation between phonological awareness, phonological processing, and language ability. A multiple stepwise regression analysis was performed to examine the phonological awareness subtasks that predict language ability. In the TD group, the syllable categorization task significantly predicted the receptive vocabulary and the performance of the Grammaticality Judgment Task. The LD group showed that the syllable counting task significantly predicted the receptive vocabulary, the expressive vocabulary, and the performance of the Grammaticality Judgment Task. The results showed that the phonological awareness performance was significantly different between the two groups. Further, correlation analysis and regression analysis showed different results for each group. The result of the phonological awareness performance predicted the language ability of each group significantly, suggesting the importance of the meta-linguistic awareness ability of phonology.

The objective of the study is to find out the effects of toddler's temperament and mother's parenting behavior on the development of vocabulary ability. The study was conducted with 299 infants between the ages of 18 and 24 months and their mothers in 47 day care centers in I city, Jeollabukdo. The results of the study are as follows. First, according to the correlation between infant's temperament and vocabulary based on the composition of temperament, approach-avoidance, adaptability, and mood showed a negative correlation with receptive and expressive vocabulary, and response intensity showed a positive correlation with receptive vocabulary. Second, according to the relation between mother's parenting behavior and infant's vocabulary ability based on the sub-factors of mother's parenting behavior, instructional parenting behavior and setting-limits parenting behavior showed a positive correlation with receptive and expressive vocabulary. Third, according to the effects of infant's temperament and mother's parenting behavior on the development of infant's vocabulary ability, as for the understanding of vocabulary, the explanation power of approach-avoidance is the highest, followed by instructional parenting behavior, response intensity, and mood. As for expressive vocabulary, the explanation power of instructional parenting behavior is the highest, followed by mood, response intensity and activity. In the development of infant's vocabulary ability, it was found that receptive vocabulary was affected the most by approach-avoidance, and expressive vocabulary was affected the most by instructional parenting behavior. Mothers will have to have interrelation skills suitable for temperament for the development of infant's receptive vocabulary, and have parenting behavior expressing the traits of things and events for the development of expressive vocabulary.

Nanta means "tapping" using percussion instruments such as drums, which is the rhythm of Samulnori, a tradtional Korean music. Nanta speech rhythm intervention program was developed and applied for the children with limited speech sound production and investigated its effect. Nanta program provided audible stimulation, various sound loudness and beats, and rhythms. Nanta program consists of three stages : Respiration, phonation and articulation with the rhythm. Six children with language development delay participated in this study. Children were encouraged to explore sounds and beats and freely express sounds and beats. Along with the rhythm, children also were encouraged to produce speech sounds by increasing the length of syllables in mimetic and imitating words. A total of 15 sessions were conducted twice a week for 40 minutes per session. For exploring the effectiveness, raw scores from preschool receptive-expressive scales (PRES) and receptive-expressive vocabulary test (REVT) were obtained and compared before and after therapy. The results demonstrated that significantly improved receptive (p=.027) and expressive language scores (p=.024) in PRES and receptive (p=.028) and expressive (p=.028) vocabulary scores following intervention using Wilcoxon signed-rank test.These findings suggest that the nanta rhythm program can be useful for improving language development and vocabulary in children with limited speech sound production.

This study analyzed (1) the utility of telepractice in language assessment and (2) parental satisfaction for telepractice. Young children with language disabilities conducted REVT through both face-to-face and telepractice system. The correlation and paired t-test were analyzed. The results showed (1) the strong correlations between telepractice and face-to-face assessment scores. However, the telepractice score was significantly lower than face-to-face in the receptive vocabulary test and (2) the overall average of parental satisfaction for telepractice was 3.6 out of 5 points. The parents showed the highest satisfaction in terms of time and convenience of telepractice while the equivalence between telepractice and face-to-face item was the lowest. This study suggested the possibility and considerations in applying telepractice of language assessment in Korea.

The purpose of this study was to examine the structural models in which early cumulative risk factors affect children's language(indicated by expressive vocabularies) and social development(indicated by peer competence) at age 3 thorough their effects on the home learning environment. To examine the hypothesized models, the data of 1,725 families from the second and the fourth waves of the Panel Study of Korean Children was used. Correlation analysis and structural equation modeling were conducted to test the models. First, the cumulative risk factors at age 1 and 3 were highly correlated, implying the stability of the risk factors over time. The more cumulative risk factors at age 1 predicted the lower level of the home learning environment at age 3, which, in turn, was significantly related to both language and social development at age 3. However, the early cumulative risk factors did not directly influence later developmental outcomes. Moreover, the cumulative risk factors at age 3 were directly related to the child's language development, but neither social development northe home learning environment. In addition, the mediational role of the home learning environment (i.e., cumulative risk factors at age 1${\rightarrow}$home learning environment${\rightarrow}$language and social development) was statistically supported. In conclusion, the early cumulative risk factors in infancy indirectly predicted children's development at age 3 through the home learning environment. The practical implications for the early intervention and support for the families with infants who are experiencing multiple risk factors were discussed.

This study was conducted to identify relationships between toddler-teacher joint attention and toddlers' vocabularies. Toddlers' vocabularies were assessed by the MacArthur Communicative Development Inventory-Korean (MCDI-K) modified by Kim (2006); joint attention episodes were observed by classification categories for engagement condition (Bakeman & Adamson, 1984). Data were analyzed by means, t-test and Pearson's correlations. Results were that : (1) receptive vocabulary of toddlers was about 1.1 times as high as their expressive vocabulary. (2) Coordinated joint attention was observed most frequently, followed by supported joint attention; coordinated joint attention was closely related to support joint attention. (3) The relationship between toddler-teacher joint attention and toddlers' vocabularies were significant in a positive direction.

Language intervention through cooking activity programs is designed to provide an efficient teaching method and improved educational environment in the field of teaching. This program addresses the effects of this program on the language development of three three-year-old infants (M;2, F;1) in the Center in Seoul. A cooking topic suitable for the age of this group was selected. The language Intervention was conducted for 50 minutes per week for a total of 25 times, and made use of vocabulary, verbs and nouns related to cooking which were evenly distributed. In this study, the Peabody Picture Vocabulary Test-Revised (PPVT-R), receptive language age (RLA) and expressive language age (ELA), and Preschool Receptive-Expressive Language Scale (PRES) were used to analyze the collected data. After the study, the cooking activity was accomplished with normal development outcomes appearing in the ability of vocabulary, receptive language, expressive language, and integrated language. There is now a solid evidence base supporting the efficacy of cooking activity in producing positive outcomes in the language development of language delayed infants. Consequently, cooking can induce their active participation and interest and extend their language abilities through various experiences.

The purpose of this study was to investigate targets to use measurement tools to communicate developed in Korea and factors consisting of questions, to examine how measurement tools to communicate applied for AAC subjects were. In the case of measuring language and communication skills targeting people with disabilities, aphasia was out of common, in the case of applying to different types of failures, it showed rare. While factors consisting of questions on measurement tools to communicate had many factors on communication limitations and many factors on impairments in body functions that limit communication, they didn't have a lot of factors on restrictions in participation caused by communication limitations and lots of environmental factors that serve as barriers or facilitators for communication. AAC intervention was applied in the order of physical disabilities, autistic disorder, mental retardation, developmental disabilities, communication disorders, although "PPVT-R", "REVT" were widely used as measurement tools to communicate used in AAC intervention experiment, there were much more cases of relying on observation than standardized tools. Based on the results, we discussed that the need of evaluating to provide ACC application and individualized education(IEP)'s grounds and the research on evaluation criteria and measurement questions should be tried.
