This study investigated children's literate behaviors in a block play area, in a block play area enriched with literacy materials, and in enriched block play with teacher intervention. The subjects were twelve 5-year-old boys who were emergent readers and writers. The results showed that literate behaviors increased in the enriched environment, compared to the non-enriched environment, and literate behaviors increased dramatically after teacher intervention in the enriched environment. The results of this study suggest that teacher intervention in block play enriched with literacy materials contributes to children's development of literacy.

Picture books, as a genre, are characterized by conveyance of ideas through linguistic texts, visual texts, and the complementary interactions between them. The writer of a picture book develops and delivers his or her ideas with textual contents written in a unique style, while the artist conveys the writer's ideas through pictures where things, objects, and figures are imbued with various emotions. Understanding a picture in a picture book requires an understanding of both the structure shown on the surface and the underlying structure that adapts and visualizes the philosophy and ideas of the writer. In light of the discussion above, this study proposes a method to help librarians improve their understanding of visual literacy for picture books, as visual literacy is required for the provision of readers' advisory services regarding picture books. This method, which is based on behavioral psychologist Rudolf Arnheim's theory of visual thinking, is expected to help librarians write picture book reviews or other secondary materials.

River-side Embankment collapse involves various causes. The embankment collapse due to internal erosion around embedded structures reaches up to more than 10% in Korea. Many studies are being attempted to prevent from the collapse of the embankment rooted from overtopping and instability as well as internal erosion. One of them is the study on the application of biopolymers. The application of biopolymers to soils are divided into enhancing strength, vegetation and erosion resistance. This study investigated the effect of biopolymer treated soil on erosion resistance. The main goal of the study is to obtain basic data for real-scale experiments to verify the effectiveness of biopolymer treated soil embankment including a review of the collapse pattern in the model embankment with various test conditions. The optimized experimental conditions were selected by examining the erosion patterns according to each induction path with three compaction degree of the model embankment. As a result of the experiment, the internal erosion rate in the embankment to which the biopolymer treated soil was applied is greatly reduced, and it could be concluded that it might be applied to the actual embankment. However, in this study, the conclusion was drawn only within the scaled-down model embankment. In order to practically apply the biopolymer treated soil to the embankment, the study considering the scale effect would be needed.
