This paper describes the conversion system which translates wordprocessor file into ODIF(Open Document Interchange Format) data stream for document interchange between heterogeneous systems and applications. We design the translator according to ODA of international base standard, FOD26 of international funtional standard, and a BosukGul V file for source document file. This system is implemented using the Microsoft Windows and the ODAC(ODA Consortium) toolkit in the PC environment.

The newly adopted Korea Geodetic Datum (a.k.a. KGD2002) calls for massive reengineering work on geospatial dataset. The main focus of our study is placed on the strategy and system implementations of the required data reengineering with a keen attention to integrated approaches to interoperability, standardization, and database utilization. Our reengineering strategy includes file-to-file, file-to-DB, DB-to-file, and DB-to-DB conversion for the coordinate transformation of KGD2002. In addition to the map formats of existing standards such as DXF and Shapefile, the newly recommended standards such as GML and SVG are also accommodated in our reengineering environment. These four types of standard format may be imported into and exported from spatial database via KGD2002 transformation component. The DB-to-DB conversion, in particular, includes not only intra-database conversion but also inter-database conversion between SDE/Oracle and Oracle Spatial. All these implementations were carried out in multiple computing environments: desktop and the Web. The feasibility test of our system shows that the coordinate differences between Bessel and GRS80 ellipsoid agree with the criteria presented in the existing researches.

Freight and passenger transport operators must converts the operation records of digital operation recording device (Digital Tachograph) that is mounted on their vehicle in a certain format, and report them to governmental agencies. However, for most of the individual carrier who cannot access a computer environment easily and are not familiar with the use of computer, it has given a big inconvenience to them because the procedures for entering the data obtained from the operation are so complicate. Therefore, in this study, a mobile system for converting the operation record file to request form of a government agency is designed and developed, so that the converted file can be submitted to the government agency in a simple way through the personal mobile device. By entering the data obtained from an actual operation recording device into the system, converting the data in the proposed algorithms, and checking the contents of the converted file in data viewer, it was confirmed that the proposed functions is working properly in the system.

Due to the increasing number of malicious software (also known as malware), methods for sharing threat information are being studied by various organizations. The Malware Attribute Enumeration and Characterization (MAEC) format of malware is created by analysts, converted to Structured Threat Information Expression (STIX), and distributed by using Trusted Automated eXchange of Indicator Information (TAXII) protocol. Currently, when sharing malware analysis results, analysts have to manually input them into MAEC. Not many analysis results are shared publicly. In this paper, we propose an automated MAEC conversion technique for sharing analysis results of malicious Android applications. Upon continuous research and study of various static and dynamic analysis techniques of Android Applications, we developed a conversion tool by classifying parts that can be converted automatically through MAEC standard analysis, and parts that can be entered manually by analysts. Also using MAEC-to-STIX conversion, we have discovered that the MAEC file can be converted into STIX. Although other researches have been conducted on automatic conversion techniques of MAEC, they were limited to Windows and Linux only. In further verification of the conversion rate, we confirmed that analysts could improve the efficiency of analysis and establish a faster sharing system to cope with various Android malware using our proposed technique.

Motion capture technology is widely used for manufacturing animation since it produces high quality character motion similar to the actual motion of the human body. However, motion capture has a significant weakness due to the lack of an industry wide standard for archiving and retrieving motion capture data. In this paper, we propose a framework to integrate, store and retrieve heterogeneous motion capture data files effectively. We define a standard format for integrating different motion capture file formats. Our standard format is called MCML (Motion Capture Markup Language). It is a markup language based on XML (eXtensible Markup Language). The purpose of MCML is not only to facilitate the conversion or integration of different formats, but also to allow for greater reusability of motion capture data, through the construction of a motion database storing the MCML documents. We propose a fuzzy string searching method to retrieve certain MCML documents including strings approximately matched with keywords. The method can be used to retrieve desired series of frames included in MCML documents not entire MCML documents.

In the past high cost and complex system configuration often discouraged hospitals from building teleradiology system or PACS(Picture Archiving and Communication System). But new standard platforms enable us to construct the same system with very low cost and simple configurations. internet as a communication channel made us overcome the regional limit and communication cost, and WWW technologies simplified the complex problems on the software developments, configurations and installations. So whoever has a Web browser to access internet can review medical images at anywhere. And we adopted DICOM technology which is a standard for medical imaging, thus we could resolve the interface problems among medical imaging systems such as modalities or archives. The implementation is comprised of three part DICOM/WWW interface subsystem, image format conversion subsystem and viewing applets which are displayed on users WWW browsers. In addition, Teleradiology intrenet PACS system includes DICOM converter that non-DICOM file format converts standard file format.

This paper designs and proposes a file conversion process to IFC file, the international standard file format for BIM, in order to ensure mutual compatability and manageability among users of commercial BIM modeling and design softwares in the civil engineering area. The proposed process insert additional properties consisting of the properties of quantity calculation codes and properties of CBS/OBS/WBS standard classification scheme, to the three dimensional object shape information of the converted IFC files, using add-in converters for commercial BIM modeling softwares. In addition, a process of integrated use of IFC files for open web-based quantity, process(4D), and construction cost(5D) management is additionally designed and implemented. Based on these works, the ultimate goal of this study is to propose a novel process for integrated use of open web-based quantity, process(4D), and construction cost(5D), from the design stage of BIM modeling to the final construction stage in the civil engineering area.

A geographic information system (GIS) generally has a great deal of geographic data and has a singular storage structure individually. It is very hard to exchange geographic data between geographic information systems which store their geographic data with incompatible formats. Moreover, since it needs large amount of storage space to store geographic data and expensive cost to input them. In this paper, we designed and implemented a SDTS (Spatial Data Transfer Standard) Data Conversion System for Gothic which is an existing geographic information system. In order to convert geographic data without loss of information, we first carefully define a mapping between SDTS data and Gothic data. Especially, since SDTS data are in the format of ISO8211, the FIPS123 library is used to access them. Because the internal data format of Gothic is not open to the public, we also use the Gothic library to access Gothic data. The SDTS data conversion system developed in this paper uses an intermediate file to convert geographic data efficiently. In addition, we use UIL (User Interface Language) to implement a graphic user interface (GUI) of our system.
