The purpose of this study was to investigate the effects of a writing program and the type of picture book used on the early stages of writing and creative writing in young children. The different stages of writing amongst young children was divided into an early stage of writing for pre-schoolers and creative writing for spontaneous expression and problem solving. The subjects comprised 36 children aged 5 from a child daycare center in Seoul. Among the KISE-BAAT and Creative tests, the writing test and creative writing test were used. The early stage of writing and creative writing were both analyzed by means of both ANCOVA and T-test. Firstly, in the subscale of the early stage of writing(ability to mark, use vocabulary, create sentences and text construction), the early stage writing of the experiment group scored higher than that of the comparison group. Secondly, in terms of the type of picture books, the group using informational picture books had greater effects on the early stage of writing than the group using narrative picture books. Thirdly, the writing program itself had a positive effect on creative writing. In the subscale of creative writing (fluency, flexibility, novelty), the group using informational picture books made greater progress in fluency and novelty than the group using narrative picture books.

Objective: The purpose of this study was to investigate grandmothers' verbal and nonverbal behaviors during young grandchildren-grandmother picture book reading. Methods: Participants were fifty-two children aged 22-42 months and their grandmothers. The researcher visited participating children's homes or child care centers and videotaped grandchildren-grandmother book reading activities. Each grandmother read two picture books for each observation. Grandmother surveys were administered after the reading activities. Parent surveys were completed by parents and were returned to the researcher. Results: First, grandmothers began reading picture books to grandchildren when children were 6 to 11-months-old or 12 to 17-months-old. They spent 5 to 10 minutes or 10 to 15 minutes at a time reading books. Second, grandmothers' most frequent verbal behavior during young grandchildren-grandmother picture book reading was 'explaining,' followed by 'questioning,' and 'providing feedback,' in that order. Grandmothers' MLU-eojeol during grandchildren-grandmother reading was 2.56. Their most frequently used nonverbal behavior was 'pointing,' followed by 'gestures.' Lastly, there was a significant difference in grandmothers' verbal and nonverbal behaviors during grandchildren-grandmother reading, depending on the grandmothers' characteristics. Conclusion/Implications: Grandmothers use various verbal and nonverbal behaviors during grandchildren-grandmother picture book reading activities, and there are significant differences in grandmothers' verbal and nonverbal behaviors with grandchildren based on grandmothers' characteristics.

Digital technology has advanced rapidly and it is anticipated that multimodal ways of meaning-making will become increasingly important. Consequently, teaching multimodal literacies is becoming a major issue in education. This study focuses on the use of picture diaries as a means of teaching multimodal literacies. Picture diaries are one of the basic and unique multimodal texts used in lower elementary level classes in Korea. A further advantage is that it is a promising text model which can be taught in unplugged ways. In order to explore the educational implications of using such picture diaries, this study sought to analyze the ways in which twenty four $1_{st}$ graders in an elementary school constructed meaning with written language and pictures in composing picture diaries. 251 picture diaries composed during several months of their $1_{st}$ grade period were analyzed based on the constant comparative method. The results indicated that the students utilized both written language and pictures in diverse and creative ways to provide their audience with more comprehensive meaning. These results indicate that teachers need to consider their students as active multimodal meaning-makers and provide their students with more opportunities to practice multimodal meaning-making and share their experiences.

This study examined the effects of a meditation program using picture books as a method of reducing young children's aggression. Data was taken from a sample of 60 four-to five-year-old children in daycare centers. This study employed a pre/post-test controlgroup design. All children of each daycare center were assigned to an experimental group(meditation program using picture books) or control group(general music meditation program). All variables were measured by the mothers and teachers of the observed children and the collected data were analyzed by independent and paired t-test. The main results of this study are as follows. Firstly, the meditation program using picture books and general music meditation program were all effective in reducing young children's aggression (aggression against things, aggression against others, verbal aggressin and total aggression) perceived by their teachers, that is, aggression against things, aggression against others and verbal aggression. Secondly, the meditation program using picture books was more effective than general music meditation program in reducing young children's aggression perceived by teachers. Thirdly, the meditation program using picture books was effective in reducing only young children's verbal aggression perceived by their mothers.

An improvement of standard encoder has been saturated recently. However, new coding method does not have a compatibility with conventional standard. To solve this problem, new concept coding method that has a semicompatibility with standard may be discussed. On the other hand, cyclic Intra-picture coding is used for access and refreshment. However, I-picture spend large amount of bits. An enhancement of I-picture is desired with keeping its refreshment performance. Further, it's a problem that quality change at the border of GOP because of its independency. To respond these, we propose the coding which is applied an inter-frame processing at the border of GOP. Applied method is the reduction of quantization error using the motion compensated inter-picture processing. In this report, we check the improvement of the efficiency and the compatibility of proposed method. As a result of examination, we recognize that the total gain is maximally 1.2dB in PSNR. Generally, the degradation of performance in standard decoding is smaller than its gain. Also the refreshment performance is tested.

본 논문에서는 MPEG2(Moving Picture Expert Group 2)비디오 디코더에서 영상데이타를 디코딩하는 기술에 관한 것으로, 종래의 동여상 처리기에서는 허프만 코드화 처리를 하여 정지영상을 부호화한후 분할기반 부호화 방식의 동영상 처리기법을 사용하였으나 1프레임의 코드화시에도 많은 계산 알고리즘이 필요하고 이미지의 닮음정도를 객관적수치로 표현할 수 없으므로 비슷한 이미지를 중복 코드화 작업 및 전송 작업을 하는 결함이 있었다. 본 눈문에서는 이를 해결하기 위하여 이미지의 닮음정도를 수치화하고 기준값 이하의 영상은 코드화 작업을 하지않고 계산된 영상 변화값에 의해 구현된 영상으로 대체하여 저장 및 전송하도록 하여 시각적으로 전혀 거부감이 없는 동영상을 구현하였다.
