The MIDS LVT terminal is changed to MIDS JTRS terminals with improved crypto modernization, enhanced throughput and frequency remapping functions due to encryption keys and bandwidth limitations. The Korean military is carrying out various performance improvement projects for the Link-16 network equipped with a MIDS JTRS terminal. In this paper, a tactical datalink unit for interfacing and forwarding(TUF) was designed and implemented to interlock and forward tactical information to the existing C2 host system (MCRC, KTMO, etc.) using MIDS JTRS terminal.
The TUF had improved scalability and maintainability through a server-client structure design that could remotely control and manage MIDS JTRS terminal interlocking and forwarding in consideration of the network operating environment. The TUF consisted of interlocking and forwarding, a basic C2 (command & control) host, and a monitoring tool. The TUF was verified through linkage with previously verified overseas tools. The TUF secured technical know-how for MIDS JTRS terminal integration by achieving the purpose of interlocking and forwarding through domestic technology development, away from the existing method of interlocking and forwarding through overseas tools. The existing weapon system without MIDS JTRS terminal linkage function could join the Link-16 network to enhance military operational operability and survivability.

MIDS LVT is communication equipment mounted with Link-16-based weapon systems to provide the Link-16 operating environment between weapon systems. Currently, the military operates the MIDS LVT BU1, but it will be changed to the BU2 and JTRS according to the performance improvement. The communication interface, message data format, and message composition of the MIDS LVT are different depending on the platform family (BU1/BU2/JTRS) and type (A,D,J). In this paper, we propose a framework based emulator design and implementation method that considers the MIDS LVT platform extension to improve these problems. In consideration of the quality attributes of the sw architecture, we designed a common based framework for modifiability, reusability, and extensibility. The MIDS LVT emulator comprises the MIDS LVT emulator processing, link interface processing, and monitoring tool. The MIDS LVT emulator was implemented by deriving and improving functions through the analysis of the functions of the previously developed overseas tools. Through the development of the MIDS LVT emulator, it can be used to develop and verify the developed Link-16 host system.
A Study on Processing XML Documents
XML can effectively express structured or semi-structured data as well as relational databases. XQuery is a query language for retrieving information for such an XML document. In this paper, an XQuery composer is designed and implemented, with an API provided for XQuery processors, and a proper processor is registered. This composer shows query results immediately processed by the processor. As this composer contains a parser for XQuery, it can compose XQuery effectively using a diverse dialog box designed for XQuery grammar. A dialog box is affiliated with a clause region, which is a region that algebra operates from the parsing tree. It can compose path expressions for an XML document easily as it shows an element tree from DTD graphically. Path expressions are composed automatically by marking elements in the structural hierarchy and by specifying the predicate of an element partially.
