Although people's anxiety about the environmental problem has been getting higher, they are not provided good quality of knowledge about the environment. Based on this situation, Ecoblog can be a new type of online community to educate the public in ecological knowledge. Especially, Ecoblog can be utilized as a method of "preventive education", and it will contribute to reduce great amounts of environmental budget to restore contaminated environment to previous condition. Ecoblog also utilizes the concept of blog which user can create and append their site with chosen themes. A weblog or a blog is a non-commercial webpage regularly updated through the use of a blogging software which allows the user to "publish" kinds of amalgamations of text and graphics to the page as posts. The technology offered in Ecoblog is utilizing the concept of 4D place and game metaphor in order to provide users the sense of participation, interaction and immersion among them and the growing community. Thus, it requires applying the CAAD technology by implementing semantically well-defined building data model as a core database to create a 4D virtual community. This research focuses on defining a 4d spatial framework suitable for developing an online ecological community. Through our study, the state-of-the-art of online community has been studied at the first step. Second, the scenario of using EcoBlog described with content, visualization and navigation are defined based on the critical features derived at the first step. Finally, a 4d spatial framework composed of semantic building data model, content and rule database is constructed to propose factors that are necessary to establish an ecological virtual community. In conclusion, our framework could enhance the comprehension and interaction between users and virtual buildings in the ecological community by integrating the concept of game design, 4D CAD and semantic data model. Such framework can be applied to any online community for an educational purpose.

XML has been become the new standard for publishing and exchanging data on the Web. However, most business data is still stored and maintained in relational database management systems. As such, there is an increasing need to efficiently publish relational data as XML data for Internet-based applications. The most important issue in the transformation is to reflect structural and semantic relations of RDB to XML schema exactly. Most transformation approaches have been done to resolve the issue, but those methods have several problems. In this paper, we discuss algorithm in transforming a relational database schema into corresponding XML schema in XML Schema. We aim to achieve not only explicit/implicit referential integrity relation information but also high level of nested structure while introducing no data redundancy for the transformed XML schema. To achieve these goals, we propose a transformation model which is redundancy free and then we improve the XML Schema structure by exploring more nested structure.

In the post-genomic era, researches on proteins as well as genes have been increasingly required. Particularly, work on protein-protein interaction and protein network construction have been recently establishing. Most biologists publish their research results through papers or other media. However, biologists do not use the information effectively, because the published research results are very large. As the growth of internet field, it becomes easy to access these research results. It is important to extract information with a biological meaning from various media. Therefore, In this paper, we efficiently extract the protein information from many open papers or other media and construct the database of the extracted information. We build a protein network from the established database and then design and implement various pathway analysis algorithms which find biological meaning from the protein network.

However, biologists do not use the information effectively, since the published research results are very large. As the growth of internet, it becomes easy to access very large research results. It is significantly important to extract information with a biological meaning from varisous media. Therefore, in this research, we efficiently extract protein-protein interaction information from many open papers or other media and construct the database of the extracted information. We build a protein network from the established database and then design and implement various pathway analysis algorithms which find biological meaning from the protein network.

Germany has started restitution process for most of collections from its occupied countries after World War II which was strongly led by the United Nations. However, this process did not include many of the plundered Jewish collections. In 1989, restitution for the Jewish's properties confiscated by the Nazis became important international issue with success in Jewish material claims against Germany in the U.S and Europe countries after German unification. German libraries has still possessed collections sequestered by the Nazis from 1933 to 1945. With Washington conference on holocaust-era assets in 1998, libraries began to sympathize with restoration of their Jewish confiscated collections. In present, by identifying the provenance of those collections at primary level, German librarians focus on various restitution activities for those collections in order to introspect and overcome their past. Specifically, the libraries publish the practical guidebook of studies on the provenance identification and open the database for the pillaged collections to the public. Few libraries start to restore the collections, but the numbers of the restituted collections are still insignificant.

XML makes it possible for data to be exchanged regradless of the data model in which it is represented or the platform on which it is stored, serving as a standard for data exchange format on the internet. Especially, it is natural to send XML data without DTD on the internet when XML is data-centric. Therefore it is needed to extract relational schema to store XML data efficiently, to optimize queries, and to publish data which have been stored in the relational database in the XML format. In this paper, we proposed a method to generate relational database in the XML documents without DTD and store XML data using upper/lower bound schema extraction technique for semistructured data. In extracting a lower bound schema, we especially show an efficient technique for creating relational schema by using simulation with is more advanced than the datalog method.

This study attempts to compare the National Library of Korea (NLK)'s cataloging in publication(CIP) records with their permanent records in the National Library of Korea(NLK)'s online public access catalogue(OPAC) database. This study compares the description of records in the NLK CIP versus NLK OPAC in terms of similarities and differences in the bibliographic elements for each record. The study selected the NLK's CIP records from November to December 2008, allowing to publish the registered CIP titles and also the NLK to make the records avaliable in their OPAC database. The finding indicate that libraries that use NLK's CIP records in their copy cataloging activity should not rely 100 per cent on the records. Verifications and modifications need to be carried out to ensure accuracy and quality of their catalogue records.
