Magazines in this 21st century which is most influenced by digital medium are in the middle position widely between traditional one; broadcastings & newspapers and new one; the mediums based on internet. Although most of the people said magazines were disappeared by growth of the digital technology, contrary to their expectations, magazines have more fixed position now by professionalizing itselves with more diverse themes. However, digital media such as Internet became a part of every day life that cannot be ignored, and digitalization of magazines was not an option but an indispensable stipulation. Especially, web version development of existing magazines is becomes an urgent issues. Therefore, the study of type of expression that can be used for existing publishers to keep their identity on digital medium is a necessary result. As the study which it sees regarding the notion and an intergral part of the Magazine Identity it leads, it materialize the construction phase of the Magazine Identity. With this categorization which will reach domestic, it compares and analyzes an outside instance, presently it constitute the expression type of a magazine that is published.

To provide more efficient and exact search result, internet systems will rely more and more on semantic web. Ontology is one of the important methods for implementation of semantic web. Ontology is used to implement an explicit formal vocabularies to share. However, important problems rise when dealing with ontology. Ontologies are typically subject to change because they are living. In order to handle ontology data change situation, a version handling system is needed to keep track of changes. For example, the queries subject to the previous ontology may become inconsistent and must be updated according to the newest version of ontology. Although many research was done in this area, there are still many problems to overcome. In this paper, we propose class and property transition graph for query transformation. The graph is created when ontology data is changed and applied to query transformation.

CoSlide is a collaborative system, extending the Jakarta Slide WebDAV server. The CoSlide server provides group workspaces for collaborators. CoSpace is a client which supports various collaborative authoring activities on the CoSlide server through the WebDAV protocol. CoSpace provides graphic user interfaces to support effective interaction among the collaborators, managing the shared resources for them. However, during collaboration, simultaneous modifications on the content of shared resources might cause conflicts among the content of the revisions made by the collaborators, leading to serious problems on project progress. In this paper, we describe an extension of the CoSpace client to solve the problem. The extended CoSpace client supports the remote version management facility through which the collaborators can manage the versions of the associated server resources in the distance. Also, to identify the changes of the text files such as program source codes, the extended client provides the facility for comparing two versions and displaying the differences in a visual manner. In addition, it provides the version management of a whole workspace and the removal of all the unnecessary versions of the designated resources.

The study was carried out for the purpose of identifying implications that should be considered in educating DDC through online within Library and Information Science curriculum. Followed by operating a NCS-based educational course utilizing printed matter and web version of DDC, two tests and survey were conducted to analyze learning outcomes, satisfaction, and preferences by learning tools. The result showed that differences in educational medium do not correlate to educational performance significantly. However, during the learning process, the mainly used medium affects the usefulness, preference and future utilization of the medium. Based on the research results, when designing DDC education using WebDewey in the future, compared to the printed version, relative understanding for utilizing the structure and its items of DDC classification, built numbers and education for understanding Web Dewey interface and function are required.

The demand for Web applications that un on databases has been rapidly increased in every area including business. Comparing to this growing demand, it still takes much time to write and maintain Web applications. In this paper, we introduce the Web script generator, WebGen that generates the Web forms as application interface and the Web scripts that process the queries by the forms operating with a database. WebGen generates five Web scripts(Search, Select, Edit, Information, and Action) from built-in templates that are the frames for those scripts by applying the declarative contents of a user-written configuration file. Each script except the Action script generates a corresponding form as user interface. Therefore, WebGen enhances Web application productivity by reducing the development time and effort for Web applications. Unlike the commercial Web script generators, WebGen supports easy version management because it is based on independent templates. Moreover, a WebGen-generated form includes not only the interested entity but also the entities that are related directly and indirectly with the interested entity.

WebDAV is an IETF standard protocol, which is an extended version of HTTP 1.1, supporting asynchronous collaborative authoring of various contents on the web. Recently, to precisely control access to the resources on a WebDAY server, the WebDAV Access Control Protocol was published. This protocol helps developers to implement advanced server functionalities in a convenient way by providing various control methods to the resources on the WebDAV server. Based on the WebDAV access control protocol, we developed Open Workspaces, which systematically support exchanging and sharing data for general visitors. An Open Workspace can be supplied as a Download-Only Open Workspace, an Upload-Only Open Workspace, or an Upload-Download Open Workspace. Any registered user can create these workspaces without bothering the system administrator. To support the Open Workspaces, we extended the Slide WebDAV server and the DAVExplorer WebDAV client, which are being used popularly.

Recently, trends of information technology development include offerings of service for personalization, intelligence, and convergence. The research suggested a new tour system that tourists can make their tour packages by applying Semantic Web technology. The system includes ontologies and inference rules for offering intelligent and personalized service. Our system called MYT (Make Your Tour-package) was successfully demonstrated by employing realistic scenarios. Current version of the MYT system needs manager's intervention to link and integrate automatically ontology subsystem and Web service. In further study, the MYT will be extended to the system including a component integrating automatically subsystems and a component capturing and processing context data from RFID/USN.

In the last few years, The Semantic Web has increased the interest in ontologies. Ontology is an essential component of the semantic web. Ontologies continue to change and evolve. We consider the management of versions in ontology. We study a set of changes based on domain changes, changes in conceptualization, metadata changes, and temporal dimension. In many cases, we want to be able to search in historical versions, query changes in versions, retrieve versions on the temporal dimension. In order to support an ontology query language that supports temporal operations, we consider temporal dimension includes transaction time and valid time. Ontology versioning brings about massive amount of versions to be stored and maintained. We present the storage policies that are storing all the versions, all the sequence of changed element, all the change sets, the aggregation of change sets periodically, and the aggregation of change sets using a criterion. We conduct a set of experiments to compare the performance of each storage policies. We present the experimental results for evaluating the performance of different storage policies from scheme 1 to scheme 5.
