  • In this paper we propose an integrated media format for a photo album including media resources and corresponding meta-data The main purpose of the integrated media is to be more reusable meta-data and to facilitate constructing a photo album from a large number of photo images as well. The proposed media format is based on MAF(multimedia Application Format) which is recently going on progress in MPEG standards. In this paper, we propose the integrated media consisting of JPEG data and content-based meta-data based on MPEG-7 MDS. We verified the usefulness of the proposed media through experiments with implementation of encoder and photo MAF player for the MAF-based media format.

  • The most commonly used PKZIP format is a ZIP file, as well as a file format used in MS Office files and application files for Android smartphones. PKZIP format files, which are widely used in various areas, require structural analysis from the viewpoint of digital forensics and should be able to recover when files are damaged. However, previous studies have focused only on recovering data or extracting meaningful data using the Deflate compression algorithm used in ZIP files. Although most of the data resides in compressed data in the ZIP file, there is also forensically meaningful data in the rest of the ZIP file, so you need to restore it to a normal ZIP file format. Therefore, this paper presents a technique to recover a damaged ZIP file to a normal ZIP file when given.

  • Recently an extension to DMB AF (Digital Multimedia Broadcasting Application Format) standard has been proposed in such a way that the extended DMB AF can include stereoscopic video and stereoscopic images for interactive service data, i.e., MPEG-4 BIFS (Binary Format for Scene) data, in addition to the existing 2D video and 2D images for BIFS services. In this paper we developed a service that provides the streaming of 3D contents in DMB AF by using MPEG-DASH (Dynamic Adaptive Streaming over HTTP) standard and validated it by implementing the client software.

  • Purpose: This study aims to analyze the effects of Brand Coolness, Brand Love, and Self-brand Connections on Word-of-mouth positively. The retail format of Starbuck in Vietnam is successful in distribution applied when it becomes the place for customers to express themselves. Consumers are now aware about Brand Coolness of the Starbucks developed in Vietnam then turn to love the brand of store and connect themselves to the brand. In this study, the closest relationship to form the basis for consumer Word-of-mouth about a brand is the relationship between Brand Coolness and Brand Love. Results: The findings show that Brand Coolness and Brand Love are important value factors in customers' minds toward their behavior, form there, it will contribute to the brand store in distribution. Research design, data and methodology: This article used the quantitative technique utilizing PLS-SEM software to test the hypothesis with 600 samples. The data obtained shows that people have Word-of-mouth about the retail format of Starbucks in Ho Chi Minh City. Conclusion: The study has demonstrated the conclusions and proposed solutions to help beverage brands build Brand Love, thereby achieving coolness, connecting brands with themselves, leading to customer Word-of-mouth in a positive way towards retail format.

  • This paper is the study of methodology for development of interface structure modules for an integrated system or steel framework structures. For development of the modules, it is used that data translation for the Steel Detail Neutral File(SDNF) format and the methodology have contacted individual systems in integrated system. The point of methology is translated system interface data with ASCⅡ format of system output and is presented with EXPRESS-G schema model. In the future, these neutral format will use structural design, engineering, facilities management, fabrication, etc. Therefore such a series of neutral formants is valuable to development of all structure fields.

  • This study is the part of development of information management system for irrigation facilities. It describes the design and prototype presentation of WISIF(Web-based geographic Information System for Irrigation Facilities). WISIF manages the IFDB(Irrigation Facilities DataBase) and offers geographic information of irrigation facilities from IFSDB(Irrigation Facilities Spatial DataBase) through World Wide Web. GeoMedia Web Map software of Intergraph is used to offer geographic information to users. GeoMedia Web Map generates vector format, so called ActivCGM. The file generated in ActiveCGM format can be downloaded fast since its size is so small and generated as an interactive map file since its format supports hyperlink.

  • Mining of association rules is to find associations among data items that appear together in some transactions or business activities. As of today, algorithms for association rule mining, as well as for other data mining tasks, are mostly applied to relational databases. As XML being adopted as the universal format for data storage and exchange, mining associations from XML data becomes an area of attention for researchers and developers. The challenge is that the semi-structured data format in XML is not directly suitable for traditional data mining algorithms and tools. In this paper we present an encoding method to encode XML tree-nodes. This method is used to store the XML data in Value Table and Transaction Table that can be easily accessed via indexing. The hierarchical relationship in the original XML tree structure is embedded in the encoding. We applied this method to association rules mining of XML data that may have missing data.

  • Many researchers have proposed the various methods to detect illegal intrusion in order to improve internet environment. Among these researches, IDS(Intrusion Detection System) is classified the most common model to protect network security. In this paper, we propose new log format instead of Apache log format for SSL integrity verification. We translate file-DB log format into R-DB log format. Using these methods we can manage Web server's integrity, and log data is transmitted verification system to be able to perform both primary function of IDS and Web server's integrity management at the same time. The proposed system in this paper is also able to use for wire and wireless environment based on PDA.

  • This letter proposes a new near-lossless image compression method with only one line buffer cost for a digital camera with Bayer format image. For such format data, it can provide a low average compression rate (4.24bits/pixel) with high-image quality (larger than 46.37dB where the error of every pixel is less than two). The experimental results show that the near-lossless compression method has better performance than JPEG-LS (lossless) with ${\delta}$ = 2 for a Bayer format image.

  • In shipbuilding, the scheduling system is susceptible to sudden changes and thus it turns to be difficult to predict the differences between schedule and production records in advance. A computer-based simulation is commonly utilized to overcome the discrepancies occurred in estimating workloads and resulting processing times. The main drawback of this simulation-based solution is its limited applicability because, in most cases, each shipyard requires specific and customized simulation environment. By standardizing the planning data of the midterm scheduling system, as proposed in this paper, the efficiency of the current simulation model can be enhanced. To present an alternative approach, this paper begins with the analysis of the complex planning data structure of several shipyards and then proceeds to construct a standard data structure based on the neutral format. An interface application is developed for the data transaction and simulation in on-line environment. As a result, a simulation-based production management of shipyards can be achieved by the efficient prediction of planning and scheduling.
