  • A Semantic Web based service description is to enable intelligent matchmaking of services by improving representational flexibility and expressiveness in service description for Web Services. Flexibility concerns the way of how a computer handles the discrepancies in the granularity and the structure of service description between different participants of web services. Expressiveness means richness in the semantic description of services (or ontological representation of each service as a concept). The main shortcoming of currently available industry standard framework for e-commerce such as UDDI and ebXML is that they do not allow much flexibility and expressiveness in the service description. In our research we analyze the requirements of extending service description based on the Semantic Web, especially in the context of DAML-S. We also propose a method to be applied to implement intelligent web services by implementing a virtual auction site, testAuction.com. Finally, we consider some theoretical issues regarding the framework for web services using ontology.

  • The Digital Multimedia Broadcasting(DMB) system is developed to offer high quality multimedia content to the mobile environment. The system adopts the MPEG-4 standard for the main video, audio and other media format. For providing interactive contents, it also adopts the MPEG-4 scene description that refers to the spatio-temporal specifications and behaviors of individual objects. With more interactive contents, the scene description also needs higher bitrate. However, the bandwidth for allocating meta data, such as scene description is restrictive in the mobile environment. On one hand, the DMB terminal renders each media stream according to the scene description. Thus the binary format for scene(BIFS) stream corresponding to the scene description should be decoded and parsed in advance when presenting media data. With this reasoning, the transmission delay of the BIFS stream would cause the delay in transmitting whole audio-visual scene presentations, although the audio or video streams are encoded in very low bitrate. This paper presents the effective optimization technique in adapting the BIFS stream into the expected bitrate without any waste in bandwidth and avoiding transmission delays inthe initial scene description for interactive DMB content.

  • The aim of this study is to propose the introduction of narrative description as an improvement to describing archives, thereby enhancing the user experience of archives. To achieve this, the study identifies the specific forms and positions of narrative elements in archives and analyzes the interaction between archival description and narrative elements. It also examines cases where narrative description has been applied in digital archives to analyze their purposes and identify the various types and characteristics of narrative description for the improvement of description and considering factors that should be taken into account when implementing narrative descriptions. Theoretical research explores the concept and role of narrative and analyzes how it is manifested in describing archives. Case studies investigate the types of narrative description in digital archives and explore their roles. Narrative description emphasizes that it can facilitate implementation by establishing the narrative identity of archivists as context constructors, conducting extensive and deep research on records, and planning collaborations with experts. However, due to the lack of concrete implementation plans for narrative description in the practical archives, further research is needed to develop models of narrative description and prepare various examples of narrative applications.

  • The main features of HILO-3 logic simulator are introduced. It is regarded as one of the most powerful logic simulator available now in electronic industry. The major functions and concepts are reviewed with some examples; circuit description using HDL (Hardware Description Language), waveform description using WDL (Waveform Description Language) and fault-free simulation for static RAM circuit. This program is expected to help the system designers, integrated circuit designers and test engineers.

  • We propose an algorithm for the robust transmission of video in error prone environment based on multiple description (MD) scheme and simple rate-distortion operators. The redundancy rate-distortion (RRD) criteria is used to split a one-layer compressed video stream into two correlated descriptions. The proposed algorithm can find more candidate points on the RRD curve than the conventional RRD based methods. A new distortion measure is also defined in this paper, which considers more realistic error environments. Since the proposed MD video coder is based on the standard H.263 coder, each description can be decoded independently by the standard H.263 decoder. Also, several descriptions can be decoded into a single stream by additional merge stage and the H.263 decoder. Simulation results show that the proposed MD video coder yields better performance than the conventional MD splitting algorithm at all bitrates both in single and two description cases.

  • In spite of recent increase in the use of avatar in Web and Virtual Reality, there has not been a service that allows users to control directly the avatar behaviors. In addition, the conventional behavior control languages required a lot of complicated information for controlling the avatar motions. Moreover, in order to apply written languages to a different task domain, it was necessary to modify or rewrite the languages. In this paper, we define Task-Level Behavior Description Language and Motion Representation Language for more simple control of the avatar behavior. The first thing allows describing the avatar behaviors in each task domain, and The second thing enables writing detailed data for motion control. And in this paper, we developed an interpreter which can automatically change the Behavior Description Language to the Motion Representation Language. So this system allow users control the avatar behavior simply with only use the Behavior Description Language. The system was applied to shopping mall and the Task-level Behavior Description Language was compared with conventional languages to see how it was more effective in behavior description.

  • Due to the improvement of mobile device capabilities, a demand for various contents service is increasing. But the differences from heterogeneous mobile devices force to develop contents which is dependent on a mobile. To solve this problem, adaptation course that reorganize contents by the device capability is needed. In this course, device description is described using device description language but there are some problems that is absence of device description repository and the way to get device description data. In this paper, I suggest device description acquisition module and define the interfaces to access device description repository that I designed and implemented.

  • Old maps of Dokdo are records with the physical specificities of a map while also holding historical meanings and evidencial values as ancient writings. Therefore more detail and meaningful descriptions are needed than other general records. However, in comparison to the high interest in these maps, there is a lack of systematic and integrative descriptions. Hence, this study aimed to propose the description elements of the old maps of Dokdo holding evidential values. For this purpose, first, literature reviews and the characteristics of the old maps of Dokdo were analyzed. Next, for determining description elements using institutions that possess old maps of Dokdo, case studies were conducted in 12 domestic and foreign institutions and compared the rules of ISAD(G). The final description elements were suggested by reflecting on the evaluation of five experts in old maps. Fifty description elements in a total of 8 areas - identity areas, context areas, content and structure areas, conditions of access and use areas, allied materials areas, note areas, description control areas, and other areas were proposed.
