This study was to examine the effectiveness of prefrontal Neurofeedback training by observing the pre and post brainwave measurement results of about Y kindergarten kids 50 (experimental group 25.comparative group 25) subjects who have shown corelation, in between the months of Mar. 2008 and Nov. 2008. As the brainwaves are adjusted by timeseries linear analysis, the result confirmed the differences of both corelation. The result of the study suggest Neurofeedback technique's possibility in positively affecting the subjects' corelation and mental state.

교육의 질이 향상됨과 동시에 학습 콘텐츠의 질 역시 향상되고 있고 어플리케이션, AI, AR 등 다양한 기술들과 접목된 다양한 교육 방식들이 존재하게 되었다. 이와 함께 스마트폰의 기술 발달과 보급률 증가에 따라 다양한 기술들과 접목된 교육용 어플리케이션들에 대한 접근 또한 쉬워지고 있다. 이에 본 논문에서는 유아의 학습 능력을 조사하여, 단어 학습에 있어 의미파악, 단어 인지, 바른 발음 지도 등을 길러 줄 수 있도록 AR 기술을 접목한 교육용 AR 어플리케이션을 설계하고 이를 구현하였다. 본 논문에서 개발한 어플리케이션은 유아의 인지와 학습 방법을 토대로 하여 바른 발음과 철자를 지도하고, 단어 학습에 있어 낱말이 가진 의미파악을 도와주며, 반복학 습을 통하여 단어를 인지하고 사용할 수 있도록 도와준다. 본 논문의 어플리케이션은 AR 기술을 융합하여 이미지만을 사용한 교육보다 쉽게 의미를 파악하는데 도움을 줄 수 있고 이에 따라 인지 능력도 상승시켜 줄 것이라 기대한다.

Objective: The purpose of this study is to explore the experiences of early childhood teachers in teaching young children with language development delays. Methods: Eight early childhood teachers with experience teaching children with language development delays were interviewed. The collected data were analyzed through transcription, coding, and theme generation processes, resulting in three main themes and seven sub-themes. Results: First, early childhood teachers mentioned difficulties in communication due to language development delays, the need for communication support with peers, and a lack of support from families. Second, the guidance for young children with language development delays was provided by considering the characteristics of these children and through collaboration among various stakeholders. Third, early childhood teachers requested tailored training for teaching young children with language development delays. They also called for the establishment of a cooperative system among early childhood education institutions, families, and specialized agencies. Conclusion/Implications: Based on the research findings, a discussion was conducted on the support needed for guiding young children with language development delays, and suggestions were made for further research in this area.

An experiment was carried out at the International Rice Research Institute in 1987 to understand the seed germination and seedling development of rice and Echinochloa species. The percentage germination of rice cultivars(IR64 for lowland-type and UPLRi-5 for upland-type) was extremely high(>90%) regardless of temperature while that of Echinochloa species ranged from 10 to 80% depending on the species. Among these, E. crus-galli ssp. kispidula had the lowest germination with less than 20% at the high temperatures ($30^{\circ}C$, $35^{\circ}C$) and about 45% at the low temperature ($25^{\circ}C$). Original seed weight gradually decreased with time white root and shoot weight increased for both rice and Echinochloa species. However, increase in root and shoot weight did not compensate for the loss of stored carbohydrate during the experimental period. The root of E. glabrescens grew from the seed on the opposite side of the shoot while for rice it grew from the same side of the seed as the shoot. Echinochloa glabrescens had a leaf blade-like expanded first leaf that contained chlorophyll while rice had an incomplete first leaf that had no leaf blade and no chlorophyll. Due to this E. glabrescens could grow independently 2 to 3 days earlier than rice.

The objective of this study was to plan a direction for the connection of the area of inquiry in daily life between infants and young children in Korea based on the analysis of the early learning standards for infants aged 0~2, and young children aged 3~4/5 in 17 different states in America. The problem of the study is as follows: What is the content area of cognitive development, science and mathematics of early learning standards regarding age? The data used in this study was collected from a total of 17 states in America in which 12 states classify infants and young children as aged 0~2 and 3~4/5 respectively and 5 states do not classify the age groups. The results obtained from the analysis of the given issues are as follows. First, in the case of the five states that showed the group aged 0~4/5, the contents related to the area of inquiry in daily life of the early learning standards were included in the mathematics and science and a part of these contents were also included in cognitive developments. In the case of the 12 states that classified the groups aged 0~2 and 3~4/5 respectively, the group aged 0~2 included cognitive developments and the group aged 3~4/5 includes mathematics and science. Second, the contents related to the area of inquiry in daily life of the early learning standards in the five states that showed the single group aged 0~4/5 include the contents in order of scientific idea, biology, physics, and the earth and space. In the 12 states that classify different age groups. Third, in the case of the states that separate age groups, the group aged 0~2 include the contents of number and operation, geometry and space while the group aged 3~4/5 include the contents of number and operations, geometry and space, and measurement. The implications of this study was that it is necessary to take into account the linking between development and characteristics of the subjects.

This study explored the contents of young children's verbal communications with their teachers in play situations. Participants were 2- to 6-year-old children. Results of observations showed 10 different verbal categories : making demands, asking questions, boasting, complementing the teacher, gaining recognition from the teacher, telling tales, explaining, making suggestions, asking permission, and insisting on one's own way. The five categories most frequently observed in older children were demanding, asking questions, boasting, explaining, and insisting on one's own way. Teachers were advised to prepare to respond more effectively to the variety of young children's verbal communication with their teachers.

This paper analyzed historical changes in early childhood curriculums from the 19th century to the present. The early childhood curriculum model of the past was based on a modernistic perspective characterized by science, rationality, objectivity, absolutism, and universality. It had been developed in terms of early human resource development to maximize efficiency and rationality for the future. In recent years, however, change occurred in the paradigm of education with the application of phenomenology, analytics, and postmodernism. Newer models for early childhood curriculum include the Reggio Emilia and Developmentally Appropriate Practice, which constitute the current mainstream of early childhood curriculum.

This study examined the effect of story dictation and dramatization on children's story construction and decontextualized language. For 12 weeks, the 22 five-year-old children in the experimental group participated in story dictation and dramatization activities while another 22 same-age children participated only in story dictation. The instruments were the children's Decontextualized Language Test(Foley, 1992) and children's Story Analysis(Knipping, 1987), revised to fit Korean grammar. Story dictation and dramatization facilitated high level story construction by children: it raised levels of story coherence and narrative form. Story dictation and dramatization also enhanced decontextualized language of children, raising their use of decontextualized language on a picture description task.

The purposes of the present study were to identify the stages of early concept development of the air in young Korean children and to compare the stages with those reported by Piaget. The subjects were 87 four, five, and six-year-old children from one kindergarten, two day care centers, and an elementary school, all located in Seoul. To collect the children's ideas of the air, individual interviews were conducted based on Piaget's Clinical Interview method. According to the results, the children formulated very unique concepts of the air, showing artificialism, anthropocentric finalism, animism, and dualism. Their concepts of the air showed a consistent developmental process which is very similar to the stages proposed by Piaget. This implies that young children's misconcepts and idosyncratic ideas are very natural and can not be eliminate easily by artificial instruction. This also means that children's internal ideas themselves should be the starting point of education.
