The Musical Slide Show MAF, which currently being standardized by MPEG, conveys the concept of combining several established standard technologies in a single file format. It defines the format of packing up MP3 audio data, along with MPEG-7 Simple Metadata Profile and MPEG-21 Digital Item Declaration metadata; with JPEC images and optional text, and synchronizes them all together to create a slideshow of JPEC image data associated to MP3 audio data during the audio playback. The implementation of Musical Slide Show MAF can be a music karaoke file where users can sing along while listening to the music, view the JPEG slideshow and reading the lyrics; or a story-telling file where users can listen to the narrated story by looking at the related illustration slideshow of the story In this paper we present the tool to producing the Musical Slide Show MAF contents. Regardless the knowledge of user on the MAF file format, the authoring tool simplify the manner of packaging several multimedia contents into single file.

Objective: It aimed at proposing the Korean Journal of Child Studies' strategy to be promoted to international journal based on the style and format of scholarly journals and journal metrics. Methods: The review of the journal in not only print version, but also an online version was done from the perspective of style and format. The total citation and impact factor were manually calculated from Web of Science Core Collection. Results: More professional level manuscript editing is required for maintaining the consistency of the style and format. The verso page and back matters should be improved to international level. Journal homepage should be reconstructed by adopting digital standards for the journal, including journal article tag suite, CrossMark, FundRef, ORCID, and text and data mining. To become an international journal, transformation into English journal and deposition to PubMed Central is mandatory. Conclusion: Since the editor's and society members' performance is top-notch, it will be possible to promote the journal up to international level soon.

Unlike paper records, accessing electronic records needs to be supported by specific combination of hardware and software. The electronic records have longer life span than the storage media, hardware, software and the formats that were used for the production of such records. Because the quality of electronic record can become deteriorated as time goes on, we need to have appropriate mechanisms to secure the long-term preservation and access to the digital information at a certain point in the future. Based on this reality, this study proposes the functions and the development method of the format registry, which efficiently supports the preservation strategy such as migration and emulation, collecting and managing technical information elements. These elements consist of the foundation of the long-term preservation of the electronic records.

We present a processing system for the Atmospheric Infrared Sounder (AIRS) sounding suite onboard Aqua satellite. With its unprecedented 2378 channels in IR bands, AIRS aims at achieving the sounding accuracy of radiosonde (1 K in 1-km layer for temperature and $10\%$ in 2-km layer for humidity). The core of the processor is the International MODIS/AIRS Processing Package (IMAPP) that performs the geometric and radiometric correction for generation of Level 1 brightness temperature and Level 2 geophysical parameters retrieval. The processor can produce automatically from received raw data to Level 2 geophysical parameters. As we process the direct-broadcast data almost for the first time among the AIRS direct-broadcast community, a special attention is paid to understand and verify the Level 2 products. This processor includes sub-systems, that is, the near real time validation system which made the comparison results with in-situ measurement data, and standard digital information system which carry out the data format conversion into GRIdded Binary II (GRIB II) standard format to promote active data communication between meteorological societies. This processing system is planned to encourage the application of geophysical parameters observed by AIRS to research the aqua cycle in the Korean peninsula.

We know that JPEG image format is one of the most popular image formats in the digital area and distribution of digital photographic drawing it is interested frequently in certain types of forensic investigation. In most case, corrupted images are shown gaudiness with the boundary of the corrupted parts. In the paper, we propose a technique to carve correct JPEG images using transformation method and the approach can be used for JPEG image file carving tool development.

Digital signatures not only provide a way of guaranteeing the integrity of data but also establish the identity of the signer. However, basic digital signature format which contains only the signature of the signer does not guarantee the correctness of its creation time, and it can not remain valid over long periods. This paper proposes a system which integrates timestamp service into digital signatures. The system provides online services for the creation and verification of long term digital signatures which can give the guarantee of the correctness of their creation times and can be proved to be valid over long periods. The proposed system can be used in the various areas such as e-commerce contracts, document archival services, and invoice applications, which requires long term digital signatures. The proposed system is tested with the KRISS timestamp service system.

Digital library system is an area of multimedia data production system which can differentiate itself from the traditional libraries. While the major role of the traditional libraries is servicing the customers, digital library system is a total system which produces new-formatted knowledge from the existing and new information, and servicing the knowledge to the customers. Thus digital library system must incorporate open and standardized document formats such as SGML, and make the knowledge shareable among the other digital library systems. In order to do show the efficient implementation for the effective digital library system, a technical alternative will be introduced as performing the Digital Library Pilot project.

With the rapid development of digital technologies potential exists to expand upon the accessibility of fashion archives and increase their use as a pedagogical tool for research. At present this is compromised due the three-dimensional, tactile nature of the objects being viewed and the fact that they are not necessarily replicable in a digital format. The aim of this paper is to examine art and design students physical object research skills and discuss how they are positioned in relation to creative tools and strategies they use to produce outcomes such as they own collections and design responses. Findings and conclusions are drawn from projects concerned with the development and use of physical and virtual archives and inform the methodology used. Traditional methods and tools within higher education are discussed together with students increased use of digital resources and innovative ways to engage students. The academic challenge of supporting student engagement in archival research across digital and physical dimensions is explored. The papers findings indicate a need for further research considering the impact of digital technology on students' physical integration with archives and the need for more structured support surrounding student physical and digital research investigations.

This paper analyzes user preferences on the basic structure of digital textbook contents based on the PDF and HTML formats. This was conducted by analysing the data from an online survey on user preferences for the representative structures of the PDF- and HTML-based digital textbook contents that are currently used on the Web. Results show that in the PDF format, the structure with TOC(Table Of Contents) links on the left screen and the main content on the right was most preferred by 82% of the respondents. In terms of the viewing method, the one that presents one page of the textbook fitted to the width of the computer screen in a single-page view was regarded as the best. Similarly, in the HTML format, the structure with TOC links on the left frame and the main content on the right using 2-frames was revealed as the most preferred by 84% of the respondents. However, the structures of the PDF- and HTML-based digital textbook contents employed by most existing Web sites go against the users' preferences. Accordingly, for digital textbook development in the future, user preferences must be considered to allow students to read the contents more easily and conveniently.
