Ubiquitous Computing System is available anytime, anywhere communications and computing systems, and information sharing and mutual cooperation between computing systems. in addition, For Ubiquitous Computing System, it is need the sensor technology to detect information of users and surrounding environment. For these reason, this paper proposed CRS(Context Recognition Switch) and DOS(Dynamic and Optimal Standard) based Context-awareness system architecture.

The digital multimedia era has come and almost everyone creates and publishes multimedia contents over the internet. When the available amount of multimedia content is exponentially increasing, searching through the sea of the multimedia content is a big problem. In this paper, we present MPEG Query Format (MPQF), which is a new standard for multimedia query language based on XML-schema. MPQF provides a standardized interface for users of heterogeneous multimedia information service providers to access their services of choice in a homogeneous way.

Since the curriculum of the department of library and information science for nurturing librarians and teacher-librarians is not standardized and the education scope and content of subjects for each exam to recruit librarians and teacher-librarians is also not standardized, the objectivity and credibility required for national exam are not guaranteed. This study is for developing a standard curriculum as one of the solutions regarding the foregoing problem. To achieve the goal of this study, first of all, the requirements for librarians and teacher-librarians and a national exam related to Teacher Certification Examination, regulation, and implementation rules were reviewed. Secondly, the justification of the suggested subjects through analyzing prior studies for developing a curriculum for library and information science was reviewed. Thirdly, the subjects resulted from the two foregoing methods were confirmed as a standard curriculum for library and information science through a focus group discussion among practicing librarians.

Digital contents is used already in near place with us. Contents of MPEG-4 standard is used to process multimedia data in field of communication, computer, broadcasting mobile etc. However, absence of copyright management and protection system and interoperability problem of right system between each corporation happened. Because MPEG establish IPMP(Intellectual Property Management and Protection) system standard in agreement with MPEG-4 system standard, proposed cooperation method to manage and protect copyright. Accordingly, in this paper, put in copyright of authorized contents management and protection extension system implementation adding MPEG-4 IPMP system like plug-in into existing MPEG-4 authorizing tool. Therefore, author edits IPMP information to protect contents or object, and process the information in system and authorize MPEG-4 digital contents that have management and protection sign according to IPMP standard. This system designed and implemented to divided into IPMP information save processor, IPMP information creation processor, media IPPM processor, XMT-A to MP4 converter IPMP extension.

ISO/TC46 is the International Organization for Standardization of practices relating to libraries, documentation and information centers, indexing and abstracting services, archives, information science and publishing. This study analyzes current trend of ISO/TC46 and the 4 subcommittees, considering recent matters in regard with identification and description of information resources: ISBN, ISSN, ISMN, ISRN, ISRC, ISAN, ISTC, etc. This research discusses also the question of how international standard numbers system are managed: endowment identifying numbers for electronic resources, component parts, and works.

High Efficiency Video Coding (HEVC) Standard, as the latest coding standard, introduces satisfying compression structures with respect to its predecessor Advanced Video Coding (H.264/AVC). The new coding standard can offer improved encoding performance compared with H.264/AVC. However, it also leads to enormous computational complexity that makes it considerably difficult to be implemented in real time application. In this paper, based on machine learning, a fast partitioning method is proposed, which can search for the best splitting structures for Intra-Prediction. In view of the video texture characteristics, we choose the entropy of Gray-Scale Difference Statistics (GDS) and the minimum of Sum of Absolute Transformed Difference (SATD) as two important features, which can make a balance between the computation complexity and classification performance. According to the selected features, adaptive decision trees can be built for the Coding Units (CU) with different size by offline training. Furthermore, by this way, the partition of CUs can be resolved as a binary classification problem. Experimental results have shown that the proposed algorithm can save over 34% encoding time on average, with a negligible Bjontegaard Delta (BD)-rate increase.

Aids to Navigation (AtoN) is an important tool for safe navigation, and the variety of information provided by AtoN is invaluable. The demand for standardized AtoN information for efficient utilization is gradually increasing, and for this purpose, the International Association of Lighthouse Authorities (IALA) has developed S-201, a standard for the management of AtoN information, and recommends its application to member countries. Notably, since Korea defines AtoNs and manages the information according to the Aids to Navigation Act, the need for definition and information management according to the S-201 standard, an international standard, is even greater. Therefore, in this study, according to the recommendation of IALA, we aimed to suggest a way to manage AtoN information by applying the S-201 standard. To this end, after comparing the classification criteria of the AtoN information of the IALA, and that of Korea's classification standards, Korea's AtoN information management plan applying the S-201 standard was presented. The results of this study provide important basic data for managing standardized digital AtoN information that is easy to use worldwide.

The Standard penetration test determines the type of soil according to soil bearing capacity, and this classifies the subsoil into many layers. Construction project managers are willing to know the depth of the present types of subsoil on site in order to make plans on earthwork stage during excavation. However the standard penetration test may not provide accurate information on subsoil type due to incorrect spacing. To solve this problem, this study propose a conceptual algorithm for determining the spacing of standard penetration test spots to essentially tests relevant locations on which to be applied the standard penetration test. This provides the acquirement of the accurate layered model volume of earthwork revised into geological columnar section. This algorithm will determine the appropriate standard penetration test spots spacing on a given size of site to optimize the accuracy of the earthwork volume, time and cost.

SOC test methodology in ultra deep submicron (UDSM) technology with reasonable test time and cost has begun to satisfy high quality and reliability of the product. A novel hierarchical test architecture using IEEE standard 1149.1, 1149.7 and 1500 compliant facilities is proposed for the purpose of supporting flexible test environment to ensure SOC test methodology. Each embedded core in a system-on- a-chip (SOC) is controlled by test access ports (TAP) and TAP controller of IEEE standard 1149.1 as well as tested using IEEE standard 1500. An SOC device including TAPed cores is hierarchically organized by IEEE standard 1149.7 in wafer and chip level. As a result, it is possible to select/deselect all cores embedded in an SOC flexibly and reduce test cost dramatically using star scan topology.
