Exponentially increasing biopathway data in recent years provide us with means to elucidate the large-scale modular organization of the cell. Given the existing information on metabolic and regulatory networks, inferring biopathway information through scientific reasoning or data mining of large scale array data or proteomics data get great attention. Naturally, there is a need for a user-friendly system allowing the user to combine large and diverse pathway data sets from different resources. We built a data warehouse - BIOWAY - for analyzing and visualizing biological pathways, by integrating and customizing resources. We have collected many different types of data in regards to pathway information, including metabolic pathway data from KEGG/LIGAND, signaling pathway data from BIND, and protein information data from SWISS-PROT. In addition to providing general data retrieval mechanism, a successful user interface should provide convenient visualization mechanism since biological pathway data is difficult to conceptualize without graphical representations. Still, the visual interface in the previous systems, at best, uses static images only for the specific categorized pathways. Thus, it is difficult to cope with more complex pathways. In the BIOWAY system, all the pathway data can be displayed in computer generated graphical networks, rather than manually drawn image data. Furthermore, it is designed in such a way that all the pathway maps can be expanded or shrinked, by introducing the concept of super node. A subtle graphic layout algorithm has been applied to best display the pathway data.

The usefulness of media representations for assessing normative standards depends in part on how accurately media reflect "on-the-ground" resource conditions. This study compared encounter standards based on still and moving pictures to assess movement effects. The study location was the Jungmoeri area of Mudeungsan Provincial Park (MPP) in Korea. A total of 50 college students participated in a laboratory experiment where they evaluated still and moving pictures constructed using Photoshop and Flash computer programs. For the maximum acceptable number (MAN), however, there was no significant difference of ratings between still and moving pictures, and the overall encounter norm curves were nearly identical. There were some "method findings" for ordering effects and percent of people moving, but for a resource manager developing standards there was no advantage to the more complex logistics of using moving pictures to assess this particular impact. The trade-offs of using more sophisticated media are discussed, and more research is needed to further explore factors such as movement of sound in evaluation of other resource conditions.

The multimedia that is characterized by multi-media, multi-features, multi-representations, huge volume, and varieties, is rapidly spreading out due to the increasing of application domains. Thus, it is urgently needed to develop a multimedia information system that can retrieve the needed information rapidly and accurately from the huge amount of multimedia data. For the content-based retrieval of moving picture, picture information is generally used. It is generally used when video is segmented. Through that, it can be a structural video browsing. The tasking that divides video to shot is called video segmentation, and detecting the cut for video segmentation is called cut detection. The goal of this paper is to divide moving picture using HMMD(Hue-Mar-Min-Diff) color model and edge histogram descriptor among the MPEG-7 visual descriptors. HMMD color model is more familiar to human's perception than the other color spaces. Finally, the proposed retrieval system is implemented as hardware.

This study examines the way poetry text is inserted in dramas and the way poets represent themselves through the drama "The climax" (2011). The drama features Lee Yuk-sa, a poet and independence activist, as a central figure and chooses a narrative structure that follows his life. The drama maximizes the lyricity and visual beauty of the drama by inserting his poems with fantastic images at the most dramatic moments of the poet's life. The image presented with the poem maximizes Lee Yuk-sa's intense hardship, while portraying the poem as a crystal of this hardship. Thus, the drama "The climax" uses Lee Yuk-sa's poetry to visualize the inner world of the central character Lee Yuk-sa. Lee Yuk-sa's poems are used in conjunction with his image to simultaneously represent the beauty of poetry and the upright spirit of the poet. This is the result of a balanced portrayal of Yi Yuk-sa, a poet and independence activist, as an intellectual who acts. The drama "The climax" is the main text that sincerely performed the representations of poems and poets through video.

This study was carried out in order to draw some implications for teaching statistical graph in mathematics education with respect to practical statistics education for promoting students' statistical literacy. We analyze 133 graphs appearing in 99 elementary textbooks of other subjects (subjects except from mathematics) by subjects and types, and identify some cases of graphs addressed by other subjects. As a results, statistical graph was most addressed in social studies, and bar graphs, line graphs, tables, and circle graphs are most used in other subjects. Moreover, there are some issues related to contents-(1) the problem of curricular sequencing between mathematics and other subjects, (2) the level of addressing ratio graph, and (3) the use of wavy lines. In terms of forms, (1) the visual variation of graphical representations, (2) representation combining multiple graphs, and (2) graphs specialized for particular subjects are drawn as other issues. We suggest some implications to be considered when teaching the statistical graph in elementary mathematics classes.

This study investigates students' conceptions of fractions from a measurement approach while providing a technological environment designed to support students' understanding of the relationships between quantities and adjustable units. 13 third-graders participated in this study and they were involved in a series of measurement tasks through task-based interviews. The tasks were devised to investigate the relationship between units and quantity through manipulations. Screencasting videos were collected including verbal explanations and manipulations. Drawing upon the theory of semiotic mediation, students' constructed concepts during interviews were coded as mathematical words and visual mediators to identify conceptual profiles using a fine-grained analysis. Two students changed their strategies to solve the tasks were selected as a representative case of the two profiles: from guessing to recursive partitioning; from using random units to making a relation to the given unit. Dragging mathematical objects plays a critical role to mediate and formulate fraction understandings such as unitizing and partitioning. In addition, static and dynamic representations influence the development of unit concepts in measurement situations. The findings will contribute to the field's understanding of how students come to understand the concept of fraction as measure and the role of technology, which result in a theory-driven, empirically-tested set of tasks that can be used to introduce fractions as an alternative way.

The representation of shamanism or shaman in Korean cinema has changed according to eras. Since the 2000s, shamanism and shaman appear more frequently than before as the main subjects and characters in movies. The full-scale exploration of shamans usually takes places in documentary works, such as <'Mudang'>(2002), (2006) and (2011). Shamans are summoned in more various appearences in feature films. In this article, we will compare and analyze the representations of shamanism and shaman in recent Korean occult genre films. (2015), (2016), and (2017) are works that utilize new subjects and visual effect styles that were difficult to see in Korean horror films before. In these three films, the meaning of shaman and gut shows distinct differences from each others. Through the analysis of these films, we would like to explore the characteristics and possibilities of Korean occult films.

In this study, the artistic background and formative nature of representative 19th century realist artists Gustave Courbet and Honoré Daumier were analyzed and applied in a fashion context. By displaying representational desires (necessary adhesions of man and society) in their work, they became characteristic matrixes of critical realism and to perceive critical realism. The purpose of the study was to apply the characteristics of critical realism to the contemporary fashion collections of Alexander McQueen. Research was conducted to analyze the characteristics that appear in the field of fashion and to review methods of expression and internal aesthetics displayed through various aspects of fashion design. Characteristics of critical realism were analyzed by researching the formativeness and periodical background of the paintings of Courbet and Daumier. Based on these characteristics, analysis was conducted to identify critical realism in the fashion collections of Alexander McQueen. Data and scope included fashion information sites, internet photo data, and video material. Critical realist characteristics were categorized into five types as follows: 'The proper borrowing of extremely realistic subjects signifies', 'satirical reconstruction and narrative composition', 'antipathetic distortions and abject representations', 'critical reproductions based on technology', and 'the maximization of ambivalent sexuality'. It was concluded that the characteristics of critical realism (recognized by the common formation of Courbet and Daumier) also appeared in Alexander McQueen's fashion collection but were inherited in a form that transcended pictorial expression due to the overall difference in use of visual arts.

This is a qualitative review of research literature on the expertise of science teachers. The study first identified a common point of view which the relevant literature shared about teacher expertise. Research methods employed in previous studies were then categorized into four groups, and the characteristics of each group of research methods were discussed. The groups of research methods included uses of questionnaires and interviews, visual representations, classroom observations and discourse analyses, and narrative inquiry. The study finally suggested what aspects of science teachers' expertise should be considered and what sorts of research methods could be employed for future research in this area.

It is well known that visual objects belonging to the same perceptual category compete for category-specific, limited-capacity attentional resource. However, it remains to be seen how perceptually identical objects interact with each other during visual analyses. Perceptually identical objects might suppress each other as much as categorically identical objects do. Alternatively, they might cooperate to generate a perceptual representation which is long lasting and robust to noise. Such possibilities were tested in the current research with three behavioral experiments using the Stroop task. As results, relative to a single distractor, Stroop interference was diluted by two different distractors of a category while it was enhanced by two perceptually identical distractors (Experiment 1). This redundancy effect disappeared when two different distractors associated with the same response were presented (Experiment 2), and it was not affected by the between- vs. within-hemisphere distractor presentations (Experiment 3). These findings indicate that the redundancy effect of distractors may be mediated by perceptual representations based on hemisphere-independent attentional resources. Overall, the current study supports the hypothesis that Stroop interference is constrained by category-specific attentional resources and further suggests that redundant presentations of a stimulus overcome such attentional constraints by facilitating perceptual processing.
