With greater utilization of web application and growth of its market, the function of such application is being expanded With today's increasing demand for high quality software, we see a sharp rise in the interest for web application test. The current trend is that web applications are being developed based on a framework of developmental environment. Hence, as the scope of that framework expands, each module of the entire web application is being configured by the combination of heterogeneous files. The distinctive characteristics of a web application are based on the fact that the framework that is provided in partially completed form controls the structure of all objects of development. The present study defines the web business logic as a minimal unit which has meaning as a unit of application for the web application. In this paper, we define web business logic as a least meaningful execution unit of web applications, propose how to generate automatically the BizUnit test code for it, and analyze the effectiveness of testing of the web application via the BizUnit test codes.

Even the short history of the Web system, the technology related to the Web system has been developed rapidly. Yet, the quality of the Web-based application software has not been improved that much. For this reason, the efficient method to develop the Web-based application software is needed. This paper describes the items necessary to develop the Web-based application software. On the basis of ISO/IEC 12207-Software Life Cycle Processes this paper mainly suggests the analysis and design stage of the Web-based model for developing software. Also, this paper describes the methods to define the process and the entity for applying contents to Web-based application software. With the web-based model suggested in this paper the Web-RoadMap Methodology of KCC Information & Communication, a system provider in Korea, has been applied to the public-domain projects. Through the application, Web-RoadMap Methodology has been proved to be an applicable model for analyzing and designing the systems based on the web environments.

This study aims at discussing development of web archiving policies in South Korea. The study is based on the understanding of that the institutional environment and efforts for keeping Web information resources are insufficient, compared to the value and importance of them. For the study, Web archiving practices are analyzed into three aspects: scope, method, and quality. Futhermore, they are graphically schematized as a comparative analysis model. Based on the model, the study classifies national Web archiving practices into seven unique types and diagnoses their cons and pros. In this context, a combined Web archiving policy is discussed as an optimal Web archiving approach. As a case study, the France National Library's Web archiving is discussed in depth and the Korean National Library's Web archiving project, OASIS, is critically analyzed. As a result, the study proposes two alternative plans for the development of Web archiving policy in South Korea.

An ontology as the core element of Semantic Web is a formal specification of a conceptualization of shared domain knowledge. The use of well-defined ontologies can increase the quality of interoperable information systems in the area of Semantic Web. However, in practice, it is not easy to develop high-quality ontologies which have no errors. Therefore, with methodologies for ontology design, various methods or tools for ontology analysis supporting for error-detection might be very helpful for ontology developers. In this paper, we propose a novel approach for analyzing the core constructs of ontology based on the Formal Concept Analysis and develop a tool that supports error-checking ontologies. Our approach can serve not only as a guidance to modify the existing ontologies, but also as a valuable tool in developing high-quality ontologies.

The desired level for multimedia services in the mobile web environment, the next generation web environment, is expected to be of PC level quality. And great efforts have been made in the development of hadware technology, communication technology, various kinds of services and standardization to support these services, In the mobile web environment, multimedia contents adaptation services should be available through supporting various kinds of devices, network abilities and users' preferences. It means that due to the variety of both desired devices' hardware specifications, called destinations, and desired QoSes, the QoSes in the destinations are not fixed or defined. If a new user wants to stream multimedia contents in a server through a new kind of terminal device, it should be considered whether the existing transcoders are able to adapt the multimedia contents. However, the existing libraries for multimedia adaptation have heavy transcoder figures which include all adaptive functions in one library, The challenge of universal access is too complex to be solved with these all in one solutions. Therefore, in this paper we propose an application independent multimedia adaptation framework which meets the QoS of new and varied mobile devices. This framework is composed of a group of unit transcoders having only one transcoding function respectively, Instead of heavy transcoders. Also, It includes the transcoder manager supporting the dynamic connections of the unit transcoders in order to satisfy end to end QoS.

새로운 비즈니스 환경 변화에 가장 빠르게 대응할 수 있는 최적의 대안으로 각광받고 있는 SOA(Service Oriented Architecture)는 현재 비즈니스 시장의 혁신과 변화를 주도하고 있다. 하지만 웹 기반인 SOA 기반 시스템은 품질평가에 대한 명확한 표준안이 제안되어 있지 않으며, 기존 소프트웨어 품질 평가를 통한 SOA 기반 시스템의 평가는 적절하지 않다. 본 논문에서는 기존 소프트웨어 품질 특성인 ISO/IEC 25000을 연구하고, AHP(Analytic Hierarchy Process) 기법을 통하여 SOA 기반 시스템에 알맞은 품질 특성을 도출하였다. 이를 통하여 SOA 기반 소프트웨어 개발 시 우선순위를 토대로 요구사항 분석이나 설계에 반영하여 최적화된 SOA 기반 시스템 구축이 가능하다.

소프트웨어 기술은 웹과 인터넷의 대중화로 소프트웨어의 품질 개선과 다양한 요구 변화에 효율적으로 대응하기 위해 급격히 발전하고 있는 추세이다. 완성된 시스템이 다양한 스테이크 홀더들의 품질에 대한 요구를 만족시키는 시스템인지의 여부를 결정하는 소프트웨어 아키텍처의 평가는 매우 중요한 부분이다. 소프트웨어 아키텍처는 프로젝트 초기의 설계 결정사항에 대한 산출물로써 시스템과 프로젝트에 많은 영향을 미치며 특정 시스템의 품질 속성은 주로 소프트웨어 아키텍처에 의해 결정된다. 본 논문에서는 품질 속성을 기반으로 체계적으로 아키텍처를 평가할 수 있는 프로세스를 제시하고 이 프로세스를 NextGen POS 시스템에 적용시켜 보았다.

Based on the network, recruitment, education services, talent testing and human resources management etc. integrated services are expanded, and efforting to raise the market share of job information site. Job information site is an alternative finding job and recruiting environment, helping job seekers to conduct self-directed researching and applying for a job online. Directly or indirectly influential factors upon value of job information site are on the rise. Not only Korea but also China has already recognized the importance of these influential factors on job information site. However, the effective rate of implementing job information site is relatively lower among Chinese job market than Korea. This study suggests that there are differences of cultural background between Korea and China, and they were at different internet infrastructure, such differences impact on different job seekers.
