The pathophysiology of developmental language disorder is a highly controversial matter. In order to investigate the neural mechanisms involved in developmental language disorders, the authors studied three dimensional regional cerebral blood flow(rCBF) using Tc-99mH-MPAO in 42 children with developmental language disorders. The results are summarized as follows : 1) 61.9% (26/42) of this series revealed decreased perfusion in SPECT. 2) Regions of hypoperfusion were seen in cerebral cortex(47.6%, 20/42), thalamus(33.3%, 14/42), basal ganglia(11.9%, 5/42) and cerebellum(7.1%, 3/42). This study suggests that developmental language disorder could be due to specific functional impairment of the local brain regions which could not detected by conventional investigations such as brain CT or EEG.

This study investigated differences in toddlers' language development depending on their teachers' types of interaction during reading of picture books. A pilot study identified teachers' types of interaction as instructional, non-immediate, and passive. Fifteen teachers recruited from 10 child-care centers located in Seoul and their 90 2-year-old toddlers participated in this study. Teachers read two picture books to a small group of toddlers each week for eight weeks. Data on the toddlers' receptive and expressive language, vocabulary, reading behavior, and book handling were collected and compared by their teachers' interaction type before and after teachers' 8-week reading of picture books. Results showed that teachers using the non-immediate interaction type had the most positive effects on toddlers' language 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.

정보화시대를 맞아 어느 때보다도 활발히 전교과에 걸쳐 학생의 의사소통의 능력을 향상하기 위한 다양한 방법이 모색되고 있다. 학교현장의 수학교육자는 수학교수-학습에서 어떤 상호작용이 일어났는지, 특히 다루기 쉬운 도구로써 계산기가 주어졌을 때 어떻게 학생의 지식 발달이 언어적 상호작용에서 이루어지는지를 알아야 한다. 본 연구는 이러한 학생의 상호작용을 분석할 때 필요한 분석도구를 개발하는 것이다. 예비연구와 본 연구를 통해 언어적 상호작용의 구성요소가 세 영역, 즉, 지식구성 진술, 사회적 상호작용 진술, 그리고 교사의 교육어 진술에서 개발되었다. 본 연구에서 개발한 자료를 이용하여 특히 학생의 지식 구성 발달에 따른 상호작용의 구성요소의 특징을 파악하고 이에 필요한 언어적 상호작용의 역할과 활성화 방안을 모색하는 연구가 가능하다.

The purpose of this study is to investigate the differences between children's internal variables (gender, temperament, development) and environmental variables (teaching efficacy, teaching - child interaction, classroom environment) The data collected for this study were analyzed using descriptive statistics, reliability analysis, correlation analysis, cluster analysis, and t-test using the SPSS 22.0 program. The results are as follows. First, the peer interaction of the infant showed a difference in sex between the types. Second, children's peer interaction showed differences in interstitial temperament, language development, and cognitive development. Third, the peer interaction of young children was different between the types of environment variables such as teaching efficacy, teacher - infant interaction, and classroom environment. As a result, it is suggested that the children's social temperament will lead to healthy peer interaction, and that language development and cognitive development will lead to a positive developmental process. In this study, the meaning and meaning of children's intergenerational behaviors in children's gender and temperament, language and cognitive development, and environmental variables such as teaching efficacy, teacher - infant interaction, I checked. In addition, it is meaningful that the positive and negative peer interactions are segmented and analyzed in detail to examine the peer interaction of infants. However, the limitation of this study is that it is not possible to investigate all the fields belonging to the infant's personal variables and environmental variables.

어린이들의 언어발달 수준이나 이해 정도를 고려한 연령별.단계별 시리즈물이 정착되고 있다. 어린이 눈높이에 맞춰 독서교육을 할 수 있다는 점에서 긍적적이지만, 국내 창작물의 절대 부족이나 개인차를 무시한 연령 제시 등 부작용도 문제로 지적된다.

인지 어휘 유형(cognitive dictionary)이란 단어 연상의 반응 어휘를 인지 유형에 따라 분류, 분석하는 것을 가리킨다. 인지 어휘 유형 개념을 McNeill의 언어 발달 연구에 준하여 논의하였다. 즉 아동의 어의(語義) 발달은 자작문(自作文) 형식(形式) 표현에서 시작되어 어휘 사용에 이른다는 것이다. 한편 Moran은 범세계적으로 유아들의 인지 어휘 유형은 단어의 동작적(動作的) 특성에 주로 의거한다는 것을 발견했는데 이는 언어의 효시에 관한 Piaget 나 Bruner의 이론과 일치하는 것이다. Moran의 인지 어휘 유형의 추가 개념은 Bruner의 심상(心象)(ikonic representation)에 의한 관계, 기능적 관계 (functional representation), 논리적(logical)관계를 포함한 단어의 연합 관계에 반영시켰다.

This study wanted to see if there was a difference in the development of counselors before and after sandplay education analysis and verbal education analysis. Ten people were selected for the sandplay education analysis and the level of counselor development before and after receiving the verbal education analysis, divided into three groups that received the verbal education analysis, and the three groups that received the language education analysis. A nonparametric test, Kruskal-Wallis test, was conducted to identify differences in the results of the pre-parametric test, and a nonparametric test, Wilcoxon signed tank test was conducted to identify differences in the pre-post test results. Studies have shown that there is a statistically significant difference in the overall development of counselors and in case of case, in the whole of sandplay education analysis groups, while those that received verbal education analysis and those that did not receive education analysis do not have a statistically significant difference in the level of counselors development. This study is meaningful as it proves that sand play education analysis is effective in the development of counselors.
