The Digital Broadcasting Satallite System consists of the Transmitter station, the Resource and Subscriber Management System, and the Receiver Test Unit. The RSMS consists or several modules such as Resource Main Module, Resource User Interface Module, Transmitter Station Interface Module, Receiver Test Unit Interface Module, Subscriber sales Outlets Module and Monitor & Control Module. In this paper we suppose the new RRMC Algorithms that is to manage efficiently the Resource and subscriber information in the Direct Broadcasting Satellite system based on client-sever features and demonstrates the implementation method of monitoring and control the system in real time. Also we explain the communication procedure between resource and subscriber managment and other equipment.

To shorten product development time and cost, integrated information managements of product, manufacturing process and resource are essential. In the area of material addressing, process engineers should make their decisions in the manner of collaborative engineering in order to reduce the manufacturing preparation time and cost in the product development and production. A digital virtual factory which is an united digital model of entire factory could be very useful for these areas. In this paper, the digital virtual factory is constructed and used for material addressing and analysis of an automotive general assembly shop. We developed the material addressing system for automotive general assembly shops using digital virtual factory models and nesting algorithms, and applied it to realistic problems of a Korean automotive company as an convenient and effective way of material addressing.

아날로그 환경에서와 마찬가지로 디지털 환경에서도 디지털 컨텐츠 하나 하나에 고유 식별기호를 부여하여야 한다. 이러한 디지털 컨텐츠를 위한 식별기호로 IETF(Internet Engineering Task Force)에서는 URI(Uniform Resource Identifier)체계 하에 인터넷 자원에 대한 접근 메카니즘을 지정하는 URL (uniform resource locator)을 사용하고 있다. 그러나 도서관의 경우 각각 다른 OPAC(Online Public Access)시스템 환경 하에서 각각 다른 URL 식별 패턴을 사용하고 있기 때문에 동일한 자원을 검색하는데 있어서 문제가 되고 있는 것이 현실이다. 이러한 문제에 착안하여 본 연구는 디지털 콘텐츠에 대한 URL 식별구문패턴의 표준화 방안을 연구하고자 한다.

Information modeling that is broadly applied in digital archiving process privides conceptual process that can be used to guide the creation of descriptions for the objects of preservation. However, it has faced with the limitations on substantially applying to the creation of preservation metadata records. This research proposes the concept of Resource Cluster in order to address these problems and efficiently describe the objects of preservation during digital archiving process. It also constructed Preservation Description Framework (PDF) based on RDF in order to substantially manifest preservation descriptions. This framework combines the structure of OAIS Reference Model and Functional Requirements for Bibliographic Records (FRBR) and can be an alternative approach to the creation of preservation metadata in more efficient and effective ways.

One of the main issues in developing a digital library is how to implement an open digital library which can be interoperable, and diverse concepts, technology and protocols have been introduced to deal with this issue. In this study, it is analysed in terms of 'metadata interoperability', and based on the analysis, 5 basic component technologies are defined as follows: application profiles, modeling, implementation, resource discovery, portal service. Therefore it explains concepts of those core features, characteristics, cases in point, standardization and technical trends.

The purpose of this study is to propose the mandatory and extensible elements of Korea Education Metadata elements for digital course resources universities in Korea. For the study, literature research, case study and interview were performed. The mandatory elements of KEM consisted of sixty nine elements, and were proposed by two phases. Also, based on interview process twelve items were newly recommended to supplement KEM elements.

This study identifies key determinants and types of participation in UCC Services. The research examines the how the major factors in perception of social presence, fun and entertainment, self-expression, arousal, human relations, positive feedback, information sharing, monetary business opportunity, and user friendliness of web structure contribute to participation in UCC Services. The data used in this study were collected by a web-based survey so that 629 internet users were available for analysis. Some of the practical implications of the results are follows. We have categorized that the type of people participating in UCC Services were readers, modifiers, remixers, and creators. Digital consumers directly connected with other consumers by producing their own digital contents. Multiple regression analysis among the creators group was not included due to small sample size. Self expression, fun and joy and the convenience of the web interface showed strong positive significant impacts on the UCC Service participation of all participation types. Information sharing, other's positive reputation and arousal showed a positive significant impact on the modifiers or remixers type groups. Monetary business opportunity and human relations were not significant in any UCC type group.

In this paper, we design and implement verification and interface application for interactive data broadcasting middleware. This application implements ACAP and OCAP verification item according to their types (format, protocol. resource, presentation). Therefore, using this application, we can verify whether digital settop-boxes used in digital terrestrial television and digital cable television conforms to the ACAP and OCAP standards. In this paper, we evaluate our proposed application using TVPLUSiTM verifier which can verify interactive TV application in real broadcasting environment. Through performance evaluation, we show that the DTB-H650F set-top-box supports OCAP and ACAP standard 80% and 95%, respectively.

In this study, users' perceptions and concerns about digital information resources were investigated, focusing on impediments to the use of digital resources, to devise measures for improvement by identifying factors that hinder the use of digital information resources. To achieve the purpose of the study, the research identifies the inconvenien ce factors and establishes the user inconvenience list based on prior research and the current status survey. Based on the derived list, a survey was conducted on users of public libraries. Through this study, it was found that the use of digital information resources can be enhanced by improving the internal library system. Specifically, it refers to improving search performance and accessibility of digital data, providing one-stop services for digital information resources through the operation of an integrated data management system, conducting customized user education, and establishing a digital information resource preservation system, e.g. web archiving. Also, improving the external environment and system, such as contracting with more libraries for digitized data use agreements, strengthening support, unifying the names and classifications of digital information resources, and simplifying the procedure for using digital information resources, is of great importance.

Recently, people are getting more interested in green energy resource and environment friendly energy resource due to the lack of energy and global warming. This study produced a solar energy resource map using LiDAR(Light Detection And Ranging) data to check if it is utilized for spatial information technology and solar energy sectors that people pay more attentions to as new recycling energy. This study assigned Ulleungdo(Island) located in Gyeongsangbuk-do as a target area. This study created the contour line with 1 meter by newly photographing LiDAR and data processing. And using this contour line, this study built DEM(Digital Elevation Model) data with 1 meter. The incidence range depending on the altitude and azimuth of sun using DEM data is used to evaluate solar energy resource. This is expected to suggest an accurate method to evaluate more reliable and more precise information of new recycling energy resource by producing solar energy resource map based on accurate and precise spatial resolution data with 1 meter level.
