The purpose of this paper is to plan and implement e-storytelling for improving children's creativity, which consists of e-storytelling, thinking questions, and character sticker canvas. Especially It makes children draw paintings feel easier by character sticker. This webapp shows the flash animation e-storytelling and gives the question to answer by painting with a fertile imagination on the canvas as transforming the character sticker. A user can input the title of painting and store it when finish the drawing. This is an educational tool which makes educatees think more and express their ideas through questions. Therefore, we can check how much children's imagination is changed and diversed by the stored paintings.

A bibliographical analysis on folktale studies in Korea by Soyoung Yoo This study is aimed primarily at taking a view of the scope and depth of folktale studies in Korea and analysing their subjects study and directions. By doing so, the researcher hopes that this can be of help to users of those studies. The researcher collected all the studies in this field since 1945 and analysed them through SAS program. Thus, the researcher found the studies on Korean folktales started in late 1960's and flourished and diversified in the middle of the 1990s. The researcher divided the collected materials into two categories, i.e., the study materials which focused on folktales themselves and studies for the exploration of applications of folktales for other purposes. Former analytical study on folktales study themselves is shown to be composed of events, characters, themes and psychological as well as value analysis. there are some comparative studies with folktales of other countries. Latter studies show that the studies are mostly for language educational purpose. Furthermore, they are for illustration, animation, traditional design, costumes studies and theme parks. There are some other studies.

In this paper, we researched the excellency of 3D graphic nursery contents for humanity and creativity education which is developed by mobile AR technology. AR technology has currentlypeople's attention because of the potential of future core contents. We allpied AR technology for kid's education of language, humanity and creativity. Well known nursery tales reconstructed by ICT technology give absorbing interest to kids, lead the curiosity of leading edge technology and friendly accept it as a part of daily life.

본 논문은 고등학교 교육과정상에서 학습자들이 오류를 범하기 쉽고, 어려워 하는 극한에 대해 보다 효과적인 지도방법을 제시한다. 현실적으로 교수활동은 교실이라는 공간에서 일정한 수업시간동안에 교사와 학습자와의 관계속에서 이루어진다. 그 속에서 학습자들은 주변의 세계를 관찰함으로써, 혹은 추측과 반박을 통해 시행착오적으로 사고함으로써 혹은 모순, 어려움, 불균형을 일으키는 주위환경에 동화 ${\cdot}$ 조절을 함으로써 자신을 적응시켜 가면서 학습하게 된다. 따라서 교수학적 의도가 미비한 환경은 학습자에게 획득하기를 기대하는 학습을 할 수 없게 한다. Brousseas의 교수학적 상황론에 근거하여 교육의 현장인 교실에서의 교사와 학생간의 상호작용에 따른 교수-학습의 중요성에 초점을 둔 본 논문은 Freudenthal의 역사발생적 원리에 의한 극한의 정의와 학습자의 오류수정을 위한 교수학습 전략으로 Lakatos의 발견술을 제안하였다. 또한 극한 개념에 대해 실생활에서 학습자에게 쉽게 동화 ${\cdot}$ 조절이 일어날 수 있는 학습 방법을 제안하였다.

본 논문은 배 전자동화 시스템에서 계통의 설비 특성에 따라, 사고발생 시 FI 정보가 발생되지 말아야 할 곳에 생기는 FI 오류에 대한 개선 알고리즘과 적용방안을 제안하고 있다. 제안한 알고리즘을 검증하기 위하며 FI 오류가 발생하는 상황을 Matlab Simulink를 이용하여 모의하였고, 그 결과를 해석하여 알고리즘의 타당성을 입증하였다. 또한 다양한 사고를 고려하여 각기 다르게 나타나는 특성들을 종합할 수 있는 적용방안도 제안하였다.

Impacts of Sea Surface Temperature (SST) assimilation to the prediction of upper ocean temperature is investigated by using a regional ocean forecasting system, in which 3-dimensional optimal interpolation is applied. In the present study, Sea Surface Temperature and Sea Ice Analysis (OSTIA) dataset is adopted for the daily SST assimilation. This study mainly compares two experimental results with (Exp. DA) and without data assimilation (Exp. NoDA). When comparing both results with OSTIA SST data during Sept. 2011, Exp. NoDA shows Root Mean Square Error (RMSE) of about $1.5^{\circ}C$ at 24, 48, 72 forecast hour. On the other hand, Exp. DA yields the relatively lower RMSE of below $0.8^{\circ}C$ at all forecast hour. In particular, RMSE from Exp. DA reaches $0.57^{\circ}C$ at 24 forecast hour, indicating that the assimilation of daily SST (i.e., OSTIA) improves the performance in the early SST prediction. Furthermore, reduction ratio of RMSE in the Exp. DA reaches over 60% in the Yellow and East seas. In order to examine impacts in the shallow costal region, the SST measured by eight moored buoys around Korean peninsula is compared with both experiments. Exp. DA reveals reduction ratio of RMSE over 70% in all season except for summer, showing the contribution of OSTIA assimilation to the short-range prediction in the coastal region. In addition, the effect of SST assimilation in the upper ocean temperature is examined by the comparison with Argo data in the East Sea. The comparison shows that RMSE from Exp. DA is reduced by $1.5^{\circ}C$ up to 100 m depth in winter where vertical mixing is strong. Thus, SST assimilation is found to be efficient also in the upper ocean prediction. However, the temperature below the mixed layer in winter reveals larger difference in Exp. DA, implying that SST assimilation has still a limitation to the prediction of ocean interior.

The purpose of this study was to examine the effect of traditional fairy tales verbal expression education on 3-year-old children's social skills. The subjects of this study were 50 3-year-old children at four different private daycare centers in the Kyungnam province. 25 preschoolers were selected as an experimental group, and the others were selected as a control group. The collected data were analyzed by the statistical package SPSS by t- test, MANOVA and ANOVA. The findings of the study were as follows: First, differences between the experimental group and the control group in social skills were significant. There were differences between the experimental group and the control group in problem solving and self-confidence. There was no difference in emotional expression and sense of order. Second, the Cohen's effect size shows that traditional fairy tales verbal expression education effects children's problem solving and self-confidence.
