The value of XML as electronic documents is increasing nowadays. The XML document has properties of semistructured data. It can be modeled as object-oriented model which can be easily adapted by object-oriented database. For storing XML documents to conventional database system, extracting schema information from the DTD of a XML document has been studied for several years. In this paper we store XML documents into object-oriented database, which preserve the semantics of the documents. We can store and query by OQL and make applications by C++ and make applications by C++ binding which is the access method of object-oriented database. Therefore, existing database applications can be used without modification.

Recently, as industries and technologies are increased, superior adhesives having more and more developed functions and properties have been demanded. In this article, to use the merits and viscoelastic properties of poly(ethylene/butylene) rubber resin and to supplement the demerits, semi-structure pressure sensitive adhesives (PSAs) are developed. Aslo, it can be said environmentally friendly PSAs because of not use the organic solvent and not emit volatile organic compounds (VOCs).

XML is becoming the de facto standard for data exchange over the Internet as a semistructured data which properties are irregular and incomplete. Therefore, to handle these data efficiently. what we use storage devices and storage techniques are Primary factors. In this paper, we developed storage techniques, which take the virtues of an object-relational database and support various query types needed for XML query languages without regard to the DTD. The techniques are capable with connecting naturally with conventional data and reducing overheads caused by the characteristics of an XML data model.

This study was attempted to suggest a new viewpoint to regulate foundation myth as Akijangsu legend narrative's antistructure. The problem is that Akijangsu legend has been regulated as reversed narrative of foundation myth in precedent research history. Following this viewpoint, it is impossible to explain context that Gangchaeyoon's Akijangsu narrative is collected in Sejong's sovereign myth. But Gangchaeyoon is changed as helper to found ideology order and his Akijangsu narrative is collected in sovereign myth's context. Therefore in this point it is necessary to sound out foundation possibility of new thesis the found myth is reversed narrative of Akijangsu legend. Choosing this standpoint, it is possible to regulate Sejong's sovereign myth as narrative dramatization of successful Akijangsu legend. At the same time it is possible to regulate Cheongkijun as Akijangsu that was situated in Sejong's sovereign myth as antagonist, competing and failing with Sejong to replace existing order by own ideological order. This study investigated that found myth is reversed narrative of Akijangsu legend.

A small library can be used as a place of cultural communication and educational experience for members of the local community that can fill the gaps of public libraries. In this study, the motives of users of small libraries were investigated. Semi-structured interviews were conducted with 45 users of small libraries, and their perceptions from their experiences were classified into four categories, 'attention', 'relevance', 'confidence', and 'satisfaction', and each factor was investigated. Small libraries showed that effective analysis, management, and design of factors related to the four motive classifications could further improve the opportunities of local community residents to find small libraries.

We present a novel method to estimate the light source direction and relight a face texture image of a single 3D model under arbitrary unknown illumination conditions. We create a virtual irradiance sphere to detect the light source direction from a given illuminated texture image using both normal vector mapping and weighted bilinear interpolation. We then induce a relighting equation with estimated ambient and diffuse coefficients. We provide the result of a series of experiments on light source estimation, relighting and face recognition to show the efficiency and accuracy of the proposed method in restoring the shading and shadows areas of a face texture image. Our approach for face relighting can be used for not only illuminant invariant face recognition applications but also reducing visual load and Improving visual performance in tasks using 3D displays.

Information Retrieval System aims towards providing fast and accurate information to users. However, current search systems are based on plain svntactic analysis which makes it difficult for the user to find the exact required information. This paper proposes the SW-IRS (Semantic Web-based Information Retrieval System) using an Ontology Server. The proposed system is purposed to maximize efficiency and accuracy of information retrieval of unstructured and semi-structured documents by using an agent-based automatic classification technology and semantic web based information retrieval methods. For interoperability and easy integration, RDF based repository system is supported, and the newly developed ranking algorithm was applied to rank search results and provide more accurate and reliable information. Finally, a new ranking algorithm is suggested to be used to evaluate performance and verify the efficiency and accuracy of the proposed retrieval system.

It has been suggested that buildings designed for strong ground motions will also have improved resistance to air blast loads. As an initial attempt to quantify this behavior, the responses of a ten story steel building, designed for the 1994 building code, with lateral resistance provided by perimeter moment frames, is considered. An analytical model of the building is developed and the magnitude and distribution of blast loads on the structure are estimated using available computer software that is based on empirical methods. To obtain the relationship between pressure, time duration, and standoff distance, these programs are used to obtain an accurate model of the air blast loading. A hemispherical surface burst for various explosive weights and standoff distances is considered for generating the air blast loading and determining the structural response. Linear and nonlinear analyses are conducted for these loadings. Air blast demands on the structure are compared to current seismic guidelines. These studies present the displacement responses, story drifts, demand/capacity ratio and inelastic demands for this structure.

The purpose of this study was to identify and understand the meaning and structure of librarians' experience of occupational socialization. Two in-depth interviews were conducted with each of the sixteen participants, practiced above 5 years in libraries and selected by theoretical sampling. Colaizzi's method of phenomenological interpretation was used to arrive at themes that represent what the experience of being a librarian meant to participants. Five thematic categories emerged from the data: 1) growing through deepening work and extending ability, 2) adapting the organization culture, 3) come to maturity along with users, 3) having double consciousness of the profession, 4) seeking self-realization as a librarian. Thus, librarians' experience means to orient toward the becoming a librarian with the professional situated the practice, and is the process librarian concretizes and realizes the ideal type of librarianship in the practice through adjustable interactive-process with environments.

According to development of Web, an amount of XML documents has been increasing. So, many researches are proceeding to verify XML data coming from clients and to store or query efficiently database. In order to verify, store and query, DTD or XML Schema of XML documents is necessary. However, Schemaless XML documents couldn't be operated since they do not have either DTD or in Schema. In this paper, we extract XML schema in order to verify XML data and store or query efficiently database from either well-formed XML or XML Schemaless documents. XML Schema extracting technique which is proposed in this paper extract Schema graph using simulation and dataguide that is a extracting technique for semistructured characteristics of XML data. Also, we propose extracting technique for XML Schema using pattern tables that are considerated with Schema graph and reusability.
