A retaining wall system suitable for a construction project is selected on the basis of subsoil conditions. If the decision-maker selects an improper system, it has a negative effect on the cost and schedule of the construction project. There have been many studies related to the models and processes for selecting optimal retaining wall systems. However, engineers who are not familiar with formal analysis methods could not easily utilize the formal methods proposed by previous studies. In order to overcome this problem, we developed a web-based decision support system called Dr. Underground, which is both physically and technically easily accessible by engineers. Dr. Underground was developed based on a selection method developed from a precedent research project. It was developed using a server-side web language ASP.NET and MS Access as a database. Decision-makers can input data about the building's condition, construction site conditions and adjacent site conditions in this system. Based on the input data, Dr. Underground recommends an optimal retaining wall system for the inputted conditions and provides detail information on the system.

As a governmental plan for real estate revitalization, remodeling vertical extension has been permitted. Thus, the Ministry of Land, Infrastructure and Transport preannounced proclaiming the revised Housing Act and establishing the remodeling basic plan, and it is anticipated that the remodeling market will be revitalized in earnest after the enforcement of remodeling vertical extension(April 25th. 2014). As vertical extension is applicable up to 3 stories, the safety of building for remodeling is becoming important, so most remodeling construction works use various methods for structural reinforcement. In this process, the selection of structural reinforcement method has depended on structural engineer's experience and knowledge and there has been a limitation in selecting the optimum structural reinforcement method which considers remodeling project characteristics. Therefore, this study analyzed the factors to determine the kinds of structural reinforcement method in a remodeling project and suggested a process to select the best structural reinforcement method of remodeling construction.

현대 사회에서 소프트웨어가 사용되는 분야가 다양해지고 그 규모가 커짐에 따라 소프트웨어 개발 프로젝트에서 일부분을 내부조직이나 외부조직에게 외주를 주는 경우가 많아지고 있다. 그래서 소프트웨어 외주관리를 어떻게 하느냐는 프로젝트의 성공에 있어서 중요한 요소로 자리잡고 있다. 소프트웨어 외주관리는 적합한 외주업체를 선정하고 선정된 외주업체를 효과적으로 관리하는 활동이다. 최근에 체계적인 외주관리를 위한 많은 노력이 시도되고 있고, 관련 표준들이 제시되고 관련 연구가 수행되고 있다. 하지만 관련 표준들과 방법론들은 그 내용이 추상적이고 구체적이지 않다. 그래서 이런 표준과 모델들에서 제시된 내용을 실무에 적용하기는 어려움이 있다. 이에 본 논문에서는 CMM, CMMI, SPICE, ISO/IEC 12207 등의 표준에서 제시하고 있는 소프트웨어 외주관리 활동과 다른 관련 표준 및 외주관리 활동에 대한 기존 연구 내용의 분석을 통해서 실무에 직접적으로 도움을 줄 수 있는 소프트웨어 외주관리를 위한 프레임워크를 연구, 개발하였다.

소프트웨어 정밀 검사는 품질 보증 활동 중 결함 제거율이 가장 높은 것으로 알려져 있지만, 비용과 시간이 가장 많이 소요되는 활동이다. 모든 프로젝트는 한정된 비용과 일정 제약을 가지고 있으므로 정형화된 프로세스로 이루어진 소프트웨어 정밀 검사를 프로젝트에서 산출된 모든 컴포넌트에 대하여 수행하는 것은 현실적으로 어렵다. 따라서 소프트웨어 정밀 검사의 효과를 극대화 하기 위한 효율적인 접근 방법이 필요하며, 본 논문에서는 효율적인 소프트웨어 정밀 검사를 수행하기 위하여 요구사항 크기와 복잡도, 설계 복잡도, 코드 복잡도 평가에 기반한 컴포넌트 우선순위 선정 기법을 제안하고 평가한다.

오늘날, 제조업계는 급변하는 글로벌 시장환경의 변화와 치열한 경쟁에 따른 새로운 도전에 직면해 있다. 이러한 엔드유저 중심의 시장의 요구에 대응하기 위해서는 새로운 기술을 발빠르게 도입하고 제품 개발의 리드타임을 단축함으로써 생산성과 비용절감을 실현할 수 있는 새로운 생산시스템의 패러다임의 도입이 요구되고 있는 시점이다. 최근 인터넷 기술의 급속한 발전과 함께 e-Manufacturing 개념의 도입으로 개별 팩토리(factory) 중심의 프로젝트에서 벗어나 대규모 분산 프로젝트 관리로 초점을 옮겨감으로써 분산화된 글로벌 생산환경의 통합이 실현되고 있다.(중략)

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.

These days, Construction industries are getting bigger, more specialized and complicated. Accordingly, the items of management is increased, also owner's organization is reduced. For this reason, various a method of construction management is introduced in the domestic construction industry. But introduction of construction management have caused increase cost because role duplication of managers. This role duplication is caused by confusion of trial and error, irrationality of system. And every construction project have peculiar properties, also owner's organization of project have various properties. This various properties is not reflected in the construction management , and the regimental method of construction management applied. In order to solving these problems, this study suggested the commissioning model for CM service reflected the properties of project and owner. This study have to selection of the critical service, service item of construction management and definition of owner's role through analysis of the properties of project, owner's capacity and requirement.

Investment on technology to obtain green energy is prevailing all over the world. The technology development project is more likely to involve multiple sub-projects, each of which is related to develop elementary technology when the project is larger and nation-wide. However, the methodologies identifying optimal combination of elementary technologies among the candidates have been very few. Hence, the purpose of this paper is to propose a novel methodology which provides an optimal combination of green energy technologies. To do so, to-be developed technologies are clustered with multiple categories. Among the technologies, based on Delphi method, the experts select a representative technology, which is indispensible to the green energy system and has the highest connectivity with other elementary technologies. Then the methodology selects an elementary technology from each technology category based on two metrics: Relatedness with representative technology and project risk. To show the feasibility of the proposed methodology, we applied the methodology to an actual windmill development project.

Recently the discussion on broadcasting and telecommunications convergence has been actively advanced, the convergence service which pulls down the guard of broadcasting and telecommunications industries is already embodied from the market. We need to clearly define a broadcasting and telecommunications convergence in order to develop promising convergence technologies based on future demands for broadcasting and telecommunications convergence. In this study, we consider both broadcasting and telecommunications as 'services-centered industries' and suggest new R&D project selection criteria. This could be used to present a new direction in R&D project management.
