Mobile web applications are being used and changed rapidly due to the growth of mobile device performance. But, cost of development environment and standards make the high development cost and low productivity. It is main reason that the design and implementation of the applications are more time consuming than general computing environments. In this paper, we propose MWeb(MobileWeb)-Framework based on the agile methodology and Ruby on Rails that is a kind of framework for supporting mobile web application development using mobile web standards. This work consists of the mobile web development architecture and agile process model. MWeb-Framework will support the same user experience to the different devices. We validates the framework by implementing the case studies through suggested mobile web development framework. As a result, we can develop the mobile web applications with productivity and quality. In the future, we will suggest how to make the MWeb-Framework standardization and practically apply the frameworks the various case studies to improve framework potentially problems.

Recently agile development process became increasing effectiveness, quality, attention to experts in customer satisfaction, as evidenced in this methodology when selecting projects promoting productive efficiency. With regard to contemporary needs and user requirements on the methodology selected to meet this paper is the product based Cross functional team suggested methodology Feature Team model to solve problems of this model, and organizing the Cross functional team, this team but this outcome (product) basis, were examined for the model that points to progress the development across multiple product as a functional unit, value-driven agile project through the Skills-based model and proposed a difference. And it examined the Agile Maturity metrics. PRINCE2 Agile Health-check entries future development direction of Agile techniques is a requirement of the project outset has studied the subject objective evaluation by the assumption that they can be changed at any time, not fixed this way and for the project team through research The proposed.

최근 모바일 디바이스의 성능향상으로 모바일 웹 애플리케이션 구동환경이 개선되고 있다. 이에 따라 모바일 웹 애플리케이션 개발 수요가 국내외적으로 증가하고 있다. 하지만 기존 PC환경과 달리 개발 환경 및 표준에 대한 고려가 적어 많은 개발비용이 소모되고 있다. 본 논문에서는 MWeb-프레임워크를 통해 최근 각광 받고 있는 웹 개발 프레임워크 기반의 개발방법론을 제안하며 이와 더불어 다양한 디바이스에서 동일한 사용이 가능하도록 모바일 웹 표준을 준수하는 개발방법론을 제안한다. Ruby on Rails기반의 모바일 웹 개발 아키텍처를 정의하고 이를 바탕으로 모바일 웹 표준을 준수하는 애자일 개발방법론을 적용한 프로세스 모델을 제안하고 기존 웹 개발 프레임워크와 개발방법론을 비교, 평가한다. 제안한 프레임워크를 통하여 신속한 개발을 수행할 수 있으며 모바일 웹 표준 환경을 준수하여 모바일 웹 애플리케이션의 품질과 신뢰성을 획득할 수 있다.

소규모 인원으로 구성한 게임 개발 프로젝트에서 품질 관리를 수행할 때 폭포수 개발과 같은 전통적인 개발 방법론을 적용하는데 많은 어려움이 있다. 이에 대한 대안으로 상황에 따라 적용할 수 있도록 일부 과정을 수정하여 스크럼 방식의 애자일방법론을 제시한다. 본 논문에서는 소프트웨어 개발에 적용하는 애자일 기법을 게임 개발에 맞춘 테스팅 방식을 적용하여 실제 개발 과정에서 효과적으로 사용할 수 있는 방식인지를 검증하고 제안한다.

Extreme programming is the most representative methodology among agile software development methodologies that is agile in business environment which change fast. As software industry is matured, usability of software quality characteristics is emphasized gradually, but effort to obtain usability in extreme programming is insufficient. In this paper, three things lacked in extreme programming are reinforced. First, roles of user interface expert are defined. Second, usability testing method to extreme programming are introduced. Third, development process and products are proposed. The proposed plan is validated by four methods, which analyze supporting software development life cycle, analyze satisfaction of CMM key process areas, analyze satisfaction of CMM practices, and analyze development of green tea shopping mail. Green tea shopping mall is improved 23％ in the estimated running time, 21％ in the learnability. Also, usability is improved 18％ in the heuristic evaluation and 16％ in the questionnaire method.

The Agile movement is a phenomenon that is part of the next phase of the software engineering evolution. At the same time, globally distributed software development is another trend delivering high-quality software to global users at lower costs. In this paper, Agile Framework for Distributed Software Development (AFDSD) has been suggested, and Chameleon project of Yahoo! Inc. has been implemented based on the framework. Also, the project has been evaluated by measuring Agile adoption and improvement levels, degrees of agility and agile project success, and comparing the performance and quality with the previous version. The overall performance and satisfaction with Chameleon increased by more than 30% since Agile techniques were adopted. Our objective is to highlight successful practices and suggest a framework to support adoption and evaluation of Agile techniques in a distributed environment.

Three kinds of typical practices to reflect the values of Agile Development Methodology were selected from a previous study. Those were Communicate using Web 2.0 collaboration tools, test-driven development (TDD, Test-Driven Development) method is adopted, and refactoring. In this study, we set up a hypothesis that the adoption of TDD project will make user satisfaction is higher. Select 100 sample projects from SourceForge(sourceforge.net), the most popular open source hosting site, the criteria is we can be determined whether operate in the project (developer least 7 people, bugs can occur more than 100, created the project since 2000). To determine whether the use of automated development tools xUnit of TDD through the CVS and SVN log analysis. Using data from the FLOSSmole and to evaluate the user experience of the project. User satisfaction of each project Rating, bug fix cycle, downloads and pageviews. Through this study, correlates of whether TDD adoption and user satisfaction, we will suggest a reflected the Agile practices new open source development methodology. As a result, it contributes to increase the maturity of the open source community.

폴리머 애자는 경량, 미려함, 소형, 비 분해 폭발 특성과 같은 다양한 장점 때문에 세라믹 애자를 대체하여 사용이 증가되고 있다. 그러나 폴리머 재료는 동일 목적의 세라믹 애자에 비하면 열화가 빠르고 성능이 저하되는 문제점이 있다. 최근 폴리머 애자의 사용기간이 10년 이상 경과하면서 이들에 대한 교체시기에 관한 관심이 증가하고 있으나 사용기간이 짧아 교체 시기론 예측하기 불가능한 실정이다. 이에 따라 본 논문에서는 국내에서 사용중인 폴리머애자 신품과 경년품의 복합가속열화시험을 실시하고 자연열화 시료와 비교하여 장기 열화특성을 평가하고 최적 교체방법을 제안하였다.

In recent years, hoping the interaction of individuals and rather than software development process and tools, and customers want software that works first, rather than a comprehensive document, in cooperation with the customer, rather than the developer negotiate a contract, to each other stick to the plan I think even more so than the value that corresponds to the change. In view of this, software development is given the autonomy and motivation to project team rather than process-oriented and have a passion and vision and human relations oriented management approach is required. In recent years, increasing the productivity benefits of agile development processes, improved quality, efficiency and customer satisfaction as is demonstrated in the methodology selected to promote the project, attention was given to the experts. Contemporary demands with regard to the methodology chosen to meet your needs, in this paper in the organization, and to solve the problems of product-based Cross functional team proposed methodology Feature Team model, this model is an organizational Cross functional team and the team is not the outcome (product) basis, were examined for the model that points to progress the development across multiple product as a functional unit, value-plan through the driven agile technique-based model and proposed a difference. And the domain analysis, required extraction by conventional JAD (joint application development) meeting the targets for the object-oriented modeling, in modeling and organize, review, aware in advance and the UML Structure and Behavior Diagrams and proposed to proceed with the project.
