  • Library of Congress introduced BIBFRAME as a new bibliographic framework to enhance web accessibility of bibliographic records and their integration to Web of data. This study introduces BIBFRAME model and its current status, reviews BIBFRAME classes and properties, and presents a mapping between MARC21 and BIBFRAME. The study aims to help the understanding the deployment of BIBFRAME in bibliographic description. BIBFRAME categorizes bibliographic entities into Work-Instance, and employs RDF/XML and URIs to identify resources and specify semantics of the resources on the Web. It also suggests an Annotation entity to provide additional information produced by users and external organizations. BIBFRAME is significant in that it presents a new paradigm of bibliographic description and expands users' information discovery in the context of Linked Data. Continuous researches are required to support its content model agnostic application to diverse resource type, which may entail a modification of BIBFRAME model and vocabulary. It also calls for guidelines for using the complicated vocabulary in a coherent way.

  • In mobile broadcasting networks, handover is an important issue to support seamless mobility. DVB-H(Digital Video Broadcasting for Handheld) standard was developed to enhance mobile features for DVB-T(Digital Video Broadcasting -Terrestrial) standard. This paper proposes new approaches for improving handover performance in the DVB-H networks. The proposed handover schemes are targeted to two different DVB-H receivers: One is for the receivers equipped with GPS devices. The other is for ones without GPS support. The first handover approach modifies the cell description table (CDT) proposed in the literature [1]. The second proposes a novel estimation technique of predefined handover region based on a new handover map table (HMT). This new handover approach estimates a predefined handover region with the measured RSSI(Received Signal Strength Indication) signal patterns. Using proposed handover algorithm, we can reduce time and power consumption. Through the computer simulations, we evaluate the performance of handover algorithm.

  • Korean nannastacids have recorded only eight species belonging to genera Campylaspis and Cumella. In this paper, Nannastacus nyctagineus Gamȏ, 1962, is redescribed and illustrated as a new species of Korean fauna in this study for the first time. Korean female specimens of Nannastacus nyctagineus correspond well with the original description by Gamȏ, 1962 based on only female specimens. Gamȏ has described that new species, Nannastacus pruinosus could be distinguished from N. nyctagineus based on only male specimens. The Korean male specimens of N. nyctagineus undoubtedly match well with the description of N. pruinosus with the following common features: the surface of the carapace is covered with numerous granules; pereonites and pleonites have similar patterns of the teeth on dorsal surface; the proportion and armature of the dactylus of pereopod 2 is similar; the number and pattern arrangement of the setae on the surface in antenna 1, pereopod 1, and uropod are the all most same. Nannastacus pruinosus Gamȏ, 1962 is proposed as a synonym of N. nyctagineus described in this study. This represents the first record on the genus Nannastacus from Korea.

  • This paper provides a description of the process in development of textbook unit on measuring length for second grade in elementary school according to action research methodology. The teaching unit development has been done based on the new national mathematics curriculum released in 2006. Mathematical communication and positive attitude toward mathematics are highly emphasized in the new curriculum. These new foci have been analysed through literature review and interviews with two incumbent teachers to be respected in the unit in an appropriate way. Three stages of development with different ways of organizing contents and different problem contexts were reported in the paper.

  • Rotation and scale variations make it difficult to solve the problem of shape description and recognition because these variations change the location of points composing the shape. However, some geometric Invariant points and the relations among them are not changed by these variations. Therefore, if points in image space depicted with the r-y coordinates system can be transformed into a new coordinates system that are invariant to rotation and scale, the problem of shape description and recognition becomes easier. This paper presents a shape description method via transformation from the image space into the invariant feature space having two axes: representing relative distance from a centroid and contour segment curvature(CSC). The relative distance describes how far a point departs from the centroid, and the CSC represents the degree of fluctuation in a contour segment. After transformation, mesh features were used to describe the shape mapped onto the feature space. Experimental results show that the proposed method is robust to rotation and scale variations.

  • Currently be proceeded a lot of researchers for 'user information demand description' for interface of an information retrieval system or Web search engines, but user information demand description for a natural language form is a difficult situation. These reasons are as they cannot provide the semantic similarity that an information retrieval model can be completely satisfied with variety regarding an information demand expression and semantic relevance for user information description. Therefore, this study using the description logic that is a knowledge representation base of OWL and a vector model-based weight between concept, and to be able to satisfy variety regarding an information demand expression and semantic relevance proposes a decision way for perfect assistances of user information demand description. The experiment results by proposed method, semantic similarity of a polyseme and a synonym showed with excellent performance in decision.

  • This paper proposes a new direction for Comparative Literature which has been deeply Eurocentric and even colonial ever since its birth. 'Comparison' in Comparative Literature has been in fact the ideological mechanism for containing, classifying, and eventually controlling all differences in the world. Literature has naturally served as a national institution of the West at epistemological and discursive level with hidden adjective "comparative". To re-conceptualize the discipline and practice of "Comparative Literature", we need to revolutionize methodology itself based on Wai Chee Dimock's idea of "Weak Theory", Foucault's "disappearance of author", and Clifford Geertz's "thick description". "Thick description" as a methodology of comparative literature re-establishes the discipline as a field of "weak theory", defusing the centrality of linguistic identity and re-making it as a "long network" of loose and missed connections. "Thick description" poses the publicness of nation-state within "confusion of tongues", problematizes the legitimacy of modern knowledge, and puts (the western) nationalism in question. With this idea as a starting point, we can re-imagine Comparative Literature anew as a field of ceaseless discourse of longer, weaker, and thicker networks of interpretation and re-interpretation of differences.

  • A new approach to impulsive noise rejection and background normalization of digitized electrocardiogram signals is presented using mathematical morphological operators that incoporate the shape information of a signal. A brief introduction to these nonlinear signal processing operators, as well as detailed description of the new algorithm, is presented. Empirical results show that the new algorithm has good performance in impulsive noise rejection and background normalization.
