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.

In this paper, a decimal floating-point arithmetic unit(DFP) was proposed and redesigned to support high speed arithmetic operation employed parallel processing technique. The basic architecture of the proposed DFP was based on the L.K.Wang's DFP and improved it enabling high speed operation by parallel processing for two operands with same size of exponent. The proposed DFP was synthesized as a target device of xc2vp30-7ff896 using Xilinx ISE and verified by simulation using Flowrian tool of System Centroid co. Compared to L.K.Wang's DFP and reference [6]'s method, the proposed DFP improved data processing speed about 8.4% and 3% respectively in case of same input data.

This research proposed an approach for interlinking bibliographic data used in the existing multicultural institutions in order to support information services of multicultural institutions. It constructed a set of linkage properties that can link the FRBR-based BIBFRAME structure with the existing metadata standards currently adopted in multicultural institutions, including MODS, EAD, and CDWA. As a result, the descriptive elements for the Work level, Instance level, Item level, statement of responsibility, subjects were established in the BIBFRAME syntax. A total of 19 upper level elements, 18 sub-elements, and 12 linkage properties were proposed for the linking of bibliographic data, so that a bibliographic environment was established that can interconnect heterogeneous metadata adopted depending on the types of collections. Through the proposed structure, it is expected that it can be applied to provide sufficient information services more efficiently by linking the dispersed bibliographic data of multicultural institutions in an integrated way.

This study aims to explore which aspects of student agency have previously been studied and the ways agent practices have been investigated in learning communities in research on science education. Results reveal five aspects of agency related to students' actions in a learning community: epistemic agency, transformative agency, educated action in science, disciplinary agency, and material agency. We delineated how agency is captured in epistemic practices, as described in the literature on each of the aforementioned aspects. We also probed into the three approaches by which previous research has examined the practices of students as agents that construct learning communities. These approaches are (a) the investigation of students' actions as representative of the agency of an entire learning community, (b) the exploration of the effects of focused student action on the structure of activity, and (c) the investigation of interactions between students as agents. We discussed the implications of previous research on the basis of each approach to understanding the diverse features of student-centered learning communities. The present work contributes to the exploration and support of students' practices as agents in the learning communities in science classrooms.

This study proposes a penetration model in soil considering the wake separation and reattachment based on the integrated force law (IFL). Rigid body dynamics, the IFL, and semi-empirical resistance function about soil are utilized to formulate the motion of the hard projectile. The model can predict the trajectory in soil considering the spherical cavity expansion phenomenon under various oblique angles and angles of attack (AOA). The Mohr-Coulomb yield model is utilized as the resistance function of the soil. To confirm the feasibility of the proposed model, a comparative study is conducted with experimental results described in the open literature. From the comparative study, the penetration depth estimated from the proposed model had about 13.4% error compared to that of the experimental results. In general, the finite element method is widely used to predict the trajectory in soil for a projectile. However, it takes considerable time to construct the computational model for the projectile and perform the numerical simulation. The proposed model only needs to the dimension of the projectile and can predict the trajectory of the projectile in a few seconds.

To structure the KOS registry, it is necessary to select a classification system that suits the characteristics of the collected KOS. This study aimed to classify domestic KOS collected through various classification schems, and based on these results, provide insights for selecting a classification system when structuring the KOS registry. A total of 313 KOS data collected via web searches were categorized using five types of classification systems and a thesaurus, and the results were analyzed. The analysis indicated that for international linkage of the KOS registry, foreign classification systems should be applied, and for optimization with domestic knowledge resources or to cater to domestic researchers, domestic classification systems need to be applied. Additionally, depending on the field-specific characteristics of the KOS, research area KOS should apply classification systems based on academic disciplines, while public sector KOS should consider classification systems based on government functions. Lastly, it is necessary to strengthen the linkage between domestic and international KOS, which also requires the application of multiple classification systems.

The high damping rubber bearings contributed to reduce a seismic force transmitted to upper structures, the material properties of rubber changes with time and the rubber with age-related degradation can affect the seismic response of structures and equipments. Therefore the seismic response of structure considering age-related degradation of isolators should be evaluated. In this paper, the stiffness and damping for isolators were defined using the aging data proposed by other researchers. The reactor containment building and the auxiliary building were selected to conduct the nonlinear analysis and the natural frequency, maximum responses, floor response spectrum(FRS) were evaluated with time using the four earthquakes with different frequency contents. According to the analysis results, the seismic responses are increased by the age-related degradation of isolators and the detail inspections should be conducted up to 20 years because it was presented that the change of FRS was high during this period.

The objectives of this study were to discuss policy for university restructuring from the viewpoint of Habermas' theory of communicative action in Covergence Society, and to provide implications for university restructuring policy in Korea. This study was conducted as a literature review, it discussed the university restructuring policy in Korea, the meaning of Habermas' theory of communicative action, and its implications for university restructuring policy. The main concept of Habermas' theory of communicative action is mutual understanding, and the theory perceives society as systems and lifeworld. Lifeworld pursues communicative rationality. University restructuring in Korea should be promoted through communication between the government and university members rather than through the forced distribution of money by state power.

This paper deals with the application of the numerical differentiation using the differential quadrature(DQ) in the curved member-like structural analysis. Derivative values of the geometry of structure are definitely needed for analyzing the structural behavior. For verifying the numerical differentiation using DQ, free vibration problems of arch are selected. Terms of curvature composed with the derivatives of arch geometry obtained herein are agreed quite well with exact values obtained explicitly. Natural frequencies subjected to terms of curvature obtained by DQ are agreed quite well with those in the literature. The numerical differentiation using DQ can be practically utilized in the structural analysis.
