An example of such a new device is a mobile phone. The demand for wireless data communication is growing rapidly. However, agencies have not yet completed the standardization of the markup language. Due to the evolution of the Mobile Device, the agencies in this field have provided different data formats with each Mobile Device Platform. Traditionally, contents are hand-tailored to suit the target devices. A key problem is that the characteristics and capabilities of mobile devices are too diverse to service the most suitable mobile contents. Owing to this problem, the need for a reusable document description language increases. In this paper, we defined Template file that is common data to service mobile devices. We proposed method that could be effective wireless web service though design and the implementation of the Call Manager & the XSL Generator. In the methodology, when requesting wireless internet service, the mobile device finds out Markup language and hardware specification of the mobile device through the Call Manager component supports. The XSL Generator component creates XSL file dynamically that is the most suitable to device. Finally, contents is serviced to each device by XSLT.

Operational Concept Descriptions or Document(OCD) shall be developed to understand stakeholder's desire for to-be-delivered system. But there is little study on methodology of OCD generation and many developers do not understand importance of OCD in Korea. According to Nicole Roberts' industry(18 U.S. companies and organizations) survey, only 30% of system development projects had OCD, too. Researchers and developers have opposing views regarding the generation of an OCD. Many researchers believe that the development and use of operational concepts at the start of large projects is essential. Alternatively, developers may view the OCD as a burden to the development process rather than an enabler due to the extensive documentation requirement. In this paper a couple of OCD guidelines were investigated to clarify how to build a CONOPS effectively and what to include. Finally, OCD for rotorcraft based Personal Air Vehicle System(PAVS) was developed as a case study. In the future, a template for generating OCD appropriate to Korean environment could be proposed.

This paper presents a query processing model in a wrapper based on the XML view tree. The query processing in a wrapper requires view composition, query translation into local sources, and generation of XML documents from local query results. We present a query processing model based on the view tree, where the XML views and the XML query is represented by the view tree. Since the view tree keeps the structure of a virtual XML document, it is easy to navigate the path expression. The view tree is also used as a template for schema generation and XML document generation as a query result. Moreover this conceptual uniform abstraction for the XML view and the user query makes it easy to support a multi-level XML view and to implement our composition mechanism.

SMIL is a declarative markup language based on XML, which enables users to make effective multimedia presentations on the web by synchronizing media objects. In this paper, we design and implement a SMIL authoring tool which support Intuitive creation of web multimedia documents and diverse practical use of created information. Besides, creation, management and authoring module of SMIL document, it offers template interface depending on network bandwidth selection for general users to create multimedia presentation a convenient way. In addition, we implement SMIL document management facility for a large number of users, by connecting SMIL contents database sever.

본 논문은 인터넷상에서 사용이 가능하며 확장성이 뛰어나 XML(eXtensible Markup Language)을 다른 문서로 변환 및 브라우징(Browsing), 프리젠테이션(Presentation)이 가능한 표준 언어인 XSL(eXtensible Stylesheet Language)을 응용한 XSL 문서 편집 시스템의 설계 및 구현에 관한 것이다. 이를 위해 XSL문서의 기본 구조 단위를 패턴(Pattern)으로 구분하여 서식 집합(Template Rule)들을 사용자 서술 방식이 아닌 사용자의 선택 방식의 자동 생성으로 구성하도록 하였다. XSL 엘리먼트 (Element)의 선택방식은 구성되어진 XML문서를 읽어 들여 문서의 엘리먼트 정보를 확장할 수 있게 하였다. 또한 XML문서와 XSL문서의 HTML(HyperText Markup Language)로의 변환을 쉽게 확인할 수 있는 사용자 인터페이스(User Interface)를 구성하며 원활하게 문서를 교환 할 수 있도록 설계 구현 하였다.

XML이 인터넷 상에서 정보 교환을 위한 새로운 표준으로 채택됨에 따라 XML 문서의 효율적인 작성과 관리를 위한 다양한 형태의 편집기가 계속 개발되고 있다. 본 논문은 기존의 XML 문서 편집기가 가진 제약점을 살펴보고 이를 해결하기 위한 새로운 형태의 XML 문서 편집기를 제안한다. 기존의 XML 문서 편집은 대부분 트리 구조를 기반으로 하여 이루어지고 있으며, 이것은 사용자로 하여금 XML에 대한 어느 정도의 지식을 필요로 한다. 그러나 XML 문서의 작성과 활용이 보편화되기 위해서는 이러한 문서 편집 방식에서 벗어나 누구나 쉽게 작성할 수 있는 환경이 제공되어야 한다. 본 논문에서는 이를 위해 트리 방식의 문서 편집뿐 만 아니라 문서의 양식을 반영하는 form을 기반으로 하는 편집 환경도 지원하는 새로운 XML 문서 편집기를 개발한다. Form외 생성은 template XML 문서와 XSLT을 통해 이루어지며 생성된 form은 내장된 HTML 브라우저를 통해 사용자에게 보여진다. Form에 입력된 사용자 데이터는 해당 XML 문서로 변환되어 데이터베이스에 저장된다.

Life cycle costing is one of the most effective approaches for the cost analysis of long-term life products, like as railroad vehicle. Life cycle costing includes the cost of concept design, development, manufacture, operating, maintenance and disposal. Especially, life cycle costing in the railroad industry has been focused on the maintenance cost. In this paper, we investigated the standard, guide and maintenance information of railroad vehicle. For this purpose, we suggested the unique templates of railroad vehicle maintenance information. We also performed maintenance cost analysis on the some sub-system of railroad vehicle for the case study.

A geometric kernel is the library of core mathematical functions that defines and stores 3D shapes in response to users'commands. We developed a light geometric kernel suitable to develop CAD/CAM application systems. The kernel contains geometric objects, such as points, curves and surfaces and a minimal set of functions for each type but does not contain lots of modeling and handling functions that are useful to create and maintain complex shapes from an idea sketch. The kernel was developed on MS-Windows NT using C++ with STL(Standard Template Library) but it is compatible with UNIX environments. This paper describes the structure of the kernel including several components: base, math, point sequence curve, geometry, translators. The base kernel gives portability to applications and the math kernel contains basic arithmetic and their classes, such as vector and matrix. The geometry kernel contains points, parametric curves, and parametric surfaces. A neutral fie format and programming and document styles are also presented in this paper.

This paper presents a documentation and development method to facilitate the certification of scientific computing software used in the safety analysis of nuclear facilities. To study the problems faced during quality assurance and certification activities, a case study was performed on legacy software used for thermal analysis of a fuelpin in a nuclear reactor. Although no errors were uncovered in the code, 27 issues of incompleteness and inconsistency were found with the documentation. This work proposes that software documentation follow a rational process, which includes a software requirements specification following a template that is reusable, maintainable, and understandable. To develop the design and implementation, this paper suggests literate programming as an alternative to traditional structured programming. Literate programming allows for documenting of numerical algorithms and code together in what is termed the literate programmer's manual. This manual is developed with explicit traceability to the software requirements specification. The traceability between the theory, numerical algorithms, and implementation facilitates achieving completeness and consistency, as well as simplifies the process of verification and the associated certification.

A smart phone has functions of both telephone and computer. The wide spread use of smart phones has sharply increased the demand for mobile commerce. The smart phone based mobile services are available anytime, anywhere. In commercial transactions, a digital signature scheme is used to make legally binding signature to prove both integrity of commercial document and verification of the signer. Smart phones are more risky compared with personal computers on the problems of how to protect privacy information. It's also easy to let proxy user to authenticate instead of the smart phone owner. In existing password or token based schemes, the ID is not physically bound to the owner. Thus, those schemes can not solve the problem of proxy authentication. To utilize the smart phone as the platform of mobile commerce, a study on the new type of authentication scheme is needed where the scheme should provide protocol to get legally binding signature and not to authenticate proxy user. In this paper, we create the mobile ID by using both the USIM and voice template of the smart phone owner. We also design and implement the user authentication scheme based on the mobile ID.
