Most of NC machines are operated by Is06983 standard called G-code, which was developed in the early days of machine tools. This G-code limits hardware performance of the currently developed high-performance hardware & machine tools. By describing only movements of tool, almost all of information of previous production departments is lost, and the machining department cannot exchange information with other departments. For adjusting new hardware environment and direct communication of CNC machines with CAD/CAM software, ISO 14649, STEP -NC is researched. This new standard stores CAD/CAM information as well as operation commands of CNC machines. In this research, the new CNC machine operated by STEP-NC was built and tested. Unlike other STEP-NC milling machines, this system uses the STEP-NC file in form of XML as data input. It makes possible for STEP-NC machines to exchange information to other databases using XML. The mentioned system of this paper loads the XML file, analyzes it, makes tool paths of two5D features with information of STEP-NC, and machines automatically without making G-code. All of software is programmed with Visual C＋＋, and the milling machine is made with table milling machine, step motors, and motion control board for PC that can be directly controlled by C＋＋ commands. All modules of software and hardware were independent, it allows convenient for substitution and expansion of the milling machine. The example 1 in ISP14649-11 that had all information about geometry and machining and the example 2 that has only geometry and tool information were used to test automatic machining by the open-architecture milling machine.

Nowadays, XML has been favored by many companies internally and externally as a means of sharing and distributing data. there are many researches and systems for modeling and storing XML documents by an object-oriented method as for the method of saving and managing web-based multimedia document more easily. The representative tool for the object-oriented modeling of XML documents is UML (Unified Modeling Language). UML at the beginning was used as the integrated methodology for software development, but now it is used more frequently as the modeling language of various objects. Currently, UML supports various diagrams for object-oriented analysis and design like class diagram and is widely used as a tool of creating various database schema and object-oriented codes from them. This paper proposes an Efficinet Query Modelling of XML-GL using the UML class diagram and OCL for searching XML document which its application scope is widely extended due to the increased use of WWW and its flexible and open nature. In order to accomplish this, we propose the modeling rules and algorithm that map XML-GL. which has the modeling function for XML document and DTD and the graphical query function about that. In order to describe precisely about the constraint of model component, it is defined by OCL (Object Constraint Language). By using proposed technique creates a query for the XML document of holding various properties of object-oriented model by modeling the XML-GL query from XML document, XML DTD, and XML query while using the class diagram of UML. By converting, saving and managing XML document visually into the object-oriented graphic data model, user can prepare the base that can express the search and query on XML document intuitively and visually. As compared to existing XML-based query languages, it has various object-oriented characteristics and uses the UML notation that is widely used as object modeling tool. Hence, user can construct graphical and intuitive queries on XML-based web document without learning a new query language. By using the same modeling tool, UML class diagram on XML document content, query syntax and semantics, it allows consistently performing all the processes such as searching and saving XML document from/to object-oriented database.

Recently, the new software paradigm in information technology (IT) is the component-based development (CBD) technology that has brought as a result of the distributed computing environment (DCE). The CBD has reduced a program developing time and has been designed to make a distributed computing environment easier in the Internet and Intranet environments. These changes of software technology have influence on the geographic information system (GIS) and the CBD technology is highly needed as a point of view of the technique and policy of the geographic information system. In this paper, we designed and implemented an Enterprise Server for the efficient development and management of GIS components. Especially, the Enterprise Server was developed with the Enterprise JavaBeans Specification 1.1 that had been proposed as an industry standard by the Sun Microsystems. The Enterprise Server can allows users to manage the Unified Modeling Language (UML) and Design Patterns for the development of GIS components, develop a GIS component container which obeyed the Open Geodata Interoperability Specification (OpenGlS), manage spatial metadata through a spatial XML (eXtensible Markup Language) engine, and implement a TESTBED server for testing and verification of developed GIS components.

XML is being used to describe components and applications in a vendor and language neutral. Therefore it already has a role in distributed system. XML is also being used as a data interchange format between components and applications in loosely coupled large-scale application. Until now, policy is described for specific applications and devices. Its use has been very limited. In current network management system, we can only invoke predefined operations and actions using policy-based network management. The main motivation for the recent interests in policy-based networks is to support dynamic adaptability of behavior by changing policy without recoding or stopping system. For these reasons we present the use of the XML for describing the policy and PIB(Policy Information Base) in COPS-PR. It improves flexibility and interoperability among heterogeneous network systems. It also can add new functionality into network components. In this paper, we propose a dynamically extensible network management architecture using XML-based PIB.

GML is a markup language presented as exchange standard for geographic information by the OGC(Open GIS Consortium). In spatial network databases, researches for supporting GML(Geographic Markup Language) can be divided into the parsing, the storing and the retrieval of GML documents. Among them, the study on the storage of GML documents is essential for their efficient retrieval. However there is little research on the storing of GML documents whereas there have been a lot of researches on the storing of n documents. Because the storage schema designed for XML documents are not appropriate for geographic information, we, in this paper, propose three storage schema for efficiently storing GML documents including geographic information in order to solve the problem that the XML storage schema store duplicate data and need to search many tables for obtaining elements. In addition, we design and implement a low-level storage manager which can store GML documents using the proposed GML storage schema.

The cyber attacks targeting the systems of national and public organizations in the front line of cyber security have been advanced, and the number of cyber attacks has been on the constant rise. In this circumstance, it is necessary to develop the security evaluation technology to prevent cyber attacks to the systems of national and public organizations. Most of the studies of the vulnerability analysis on the information systems of national and public organizations almost focus on automation. In actual security inspection, it is hard to automate some parts. In terms of security policies for threats, many different plans have been designed and applied in the managerial, physical, and technical fields, giving particular answers no matter how they are subjective or situational. These tendencies can be standardized in OCIL(Open Checklist Interactive Language), and partial automation can be achieved. Therefore, this study tries to implement XML Converter in order for OCIL based security level evaluation with typical evaluation questions.

The importance of EDI has been so emphasized that we need exchange/maintain electronic documents effectively, and convert then to other formats. The traditional EDI, however, is facing on the limitation of growth because of it's high expense, and the closenees of sharing information. The EDls of next generation, like open EDI, object-oriented EDI, and Internet EDI, have appeared to solve these problems. Finally, XML/EDl, which is very effective to solve these kinds of problems, is now replacing the traditional EDI and the HTML in Internet and is influencing on e-Business. So, we are going to suggest a solution which uses XML/EDl as a substitute for the traditional one. First, we analyzed the problems of the traditional EDI system and organized the structure of XML/EDl system. Next, we have developed the prototype of Internet bookstore to show the effectiveness and strength of XML/EDl over the traditional EDI.

1995년 이후 NGIS(National Geographic Information System) 사업의 시작과 함께 활성화되기 시작한 GIS는 1990 년대 말 인터넷의 급속한 보급으로 인하여 비약적인 발전을 거듭하였다. 최근에는 무선 인터넷의 확산과 함께 모바일 GIS가 등장하였으며, OGC(Open GIS Consortium)에서는 효율적인 지리정보의 저장과 전달을 위해 GML(Geographic Markup Language)을 제안하였다. 본 논문에서는 GVM(General Virtual Machine)기반의 모바일 디바이스에서 GML 문서를 처리하기 위한 XML 파서와 맵매니저(MapManager)를 설계하고 구현하였다. XML 파서는 서버로부터 GML문서를 다운로드 받아서 파싱과정을 거쳐서 DOM(Document Object Model)형태의 자료구조를 생성한다. 맵매니저는 DOM 구조를 입력으로 받아서 모바일 디바이스의 화면에 지도를 표시하고, 사용자 상호작용을 처리한다.
