As construction project has been becoming larger, specialized and complicated, it is important to utilize a lot of information that is made by diverse participants. Especially this information is mainly produced in construction site that plays a leading role in construction project. The problem of information exchange between participants of construction site causes decline of construction productivity. So as to resolve this problem, there is a many interest in BIM(Building Information Modeling) that makes and manages a necessary data during building life cycle. But in Korea construction industry, applying BIM in construction phase is less active than in design phase. Through studying previous research, this study classify the main cause of failure related to information exchange in framework construction. And by interviewing expert, it draw a work that is possible to apply BIM. Next through analyzing framework construction site that is applied with BIM, this study proposes specific information flow model for supporting work by BIM.

소프트웨어 개발은 복잡도가 높고 가시성 확보가 어려워 전략적으로 접근해야 한다. 일반 개발 프로젝트에서 개발 전략은 특정 개발 모델과 프로젝트 관리 기법을 사용하겠다는 것이 주류를 이루고 있다. 이러한 방법은 각 개발 단계에서 업무를 진행하는 프로젝트 참여자가 프로젝트 전체를 보지 못하고 각자의 전문 분야만을 국지적으로 개발하여 초기에 의도된 대로 개발되지 않는 결과를 초래하는 경우가 다반사여서 개발 전략으로서의 역할을 적절히 수행하지 못하는 문제가 있다. 본 연구에서는 리스크 기반의 개발 전략을 제시한다. 개발 프로젝트 전체는 물론 개발의 각 단계 별로 전략이 존재할 수 있으며, 전사 차원과 프로젝트 차원의 전략이 존재한다. 분석한 리스크 레벨에 차등적으로 개발 리소스를 할당하고, 개발 기법을 사용하고, 리뷰 및 검증 활동을 진행하여 제한된 개발 리소스를 합리적이고 적절하게 사용하여 개발하고, 개발 과정을 모니터링 및 제어하는 접근법이다. 이미 개발의 일부인 테스팅 분야에서는 리스크 기반 테스팅 전략이라는 이름으로 활용하여 직간접적인 효과를 보고 있으며, 같은 개념을 개발 전체로 확장하여 개발 전략으로 체계화하여 제시한다.

The web-based crowdfunding platform provides small-cap companies the opportunity to reduce financial risks and to reliably produce new products through pre-orders. Meanwhile, crowdfunding projects are also helping companies as a channel to test new products before mass production. Despite these advantages, from the point of view of businesses and consumers, it is true that web-based crowdfunding platforms have limitations in the retail environment. For example, the limited social elements of a web-based platform are somewhat in conflict with the basic characteristics of crowdfunding projects - which inevitably demand high social influences for the success. As such, understanding the mechanisms of social factors of crowdfunding platforms from the consumers' perspective is important. Therefore, in this study, we empirically tested the effect of social factors of crowdfunding platform on consumer participation and evaluation. Based on the Social Influence Theory and Social Presence Theory, we developed a conceptual framework where the social group size and social presence of other backers were the independent variables and the purchaser's intention to participate as the dependent variable. In the results, the size of the social group size and the perceived social presence have a significant positive effect on purchaser's participation intent. In addition, the social presence had a greater influence on the purchaser's intention to participate than the size of the sponsor's social group. We believe that our findings contribute to the extant literature by empirically demonstrating the valid effect of social factors of crowdfunding platforms on consumer evaluations.

It has been passed $5\~6$ years since Construction Management introduced in Korea, but a few government projects have been presented as CM instances. We performed CM service, on behalf of the foreign Client, in the Insa-dong construction, I-Project. Even though there were many limits in cost, time and other aspects, we have attained satisfaction of the Client and successful businesses of all the construction parties as adopting the advanced management methods. Many advanced construction methods have been applied for the purpose of time reduce, cost save and quality assurance as well as to the webbased project management has been imported to overcome the limits of time and place. They have actualized to increase the productivity of the project by managing the floor to floor cycle and quality systemically pursuant to ISO 9002, and by adopting Real-name construction and completion system (or individual activity. While carrying out this project, it is possible to establish mutual reliability and understanding enable to resolve the issues occurring in the early stage due to insufficient understanding of CM, lack of communications and team work, indistinct work scope through continuos training and conferences. Additionally, we became to share business targets among the parties and promoted the project in confidence. We wish that the success of I- project to be rated as a standard model of CM in Korea.

많은 개발자가 참여하는 대형 소프트웨어 시스템 개발의 효율성 증대를 위해서는 컴포넌트 간 인터페이스의 효과적인 관리가 필수적이다. MDMS는 컴포넌트간의 인터페이스 정의 및 변경 이력 관리, 인터페이스 기술서 자동 생성, 소스 코드 자동 생성 등의 기능을 제공하는 도구이다. 한화탈레스는 1998년 MDMS를 처음 개발하여 적용한 이후 다양한 국방 소프트웨어 시스템 개발에 적용하여 소프트웨어 개발 생산성 향상에 효과를 보았다. 하지만, MDMS를 다양한 프로젝트에 적용하는 과정에서 최초 개발시 고려하지 못했던 여러 문제점 및 한계를 발견하였다. 이러한 문제점 및 한계는 다양한 프로젝트의 특성 지원 미흡, 형상관리 및 유지보수 문제, 프로젝트 간 메시지 재사용 미지원, 취약한 보안 등 이다. 본 논문에서는 이를 해결하기 위하여 네가지 개선방안을 제시한다. 첫 번째, 다양한 프로젝트에 적용이 가능한 유연한 SW 구조로 개선해야 한다. 두 번째, 통일되고 일관된 형상관리와 함께 전담 개발 및 유지보수 조직이 필요하다. 세 번째, 프로젝트간 메시지의 재사용 지원을 위한 방안으로 프로젝트 별 MDMS 운용이 아닌 통합된 MDMS의 운용이 필요하며, 그를 통하여 다른 프로젝트의 인터페이스 정의를 상호 참조할 수 있는 구조를 적용해야 한다. 마지막으로, 외부 협력업체와의 협업을 위한 보안 대책을 수립하고, 관련 보안 기능을 지원하여 사외의 협력업체의 개발자가 직접 MDMS에 접속하여 개발할 수 있도록 개선해야 한다.

The construction industry is huge-there are lots of project organizations and many different people who work on them. Conflict will occur in any long - term relationship and it happens in personal, professional, family, and social relationships. Disputes between parties to construction projects are of great concern to the industry. The study of construction industry disputes, and the causes of those disputes, is essential. The purpose of this study is to identify the root causes of conflicts in construction industry. A questionnaire field survey was conducted to investigate the root causes of construction conflicts. The professionals working for owner, contractor and consultants were targeted for the collection of data. Descriptive analysis such as mean score and standard deviation as well as factor analysis was employed to find underlying factors related to conflicts in construction field. Student's t-test and ANOVA test tools were used to compare the perceptions of various categories of population and project. Factor analysis was used to group the numbers of conflict causes. This study reveals four root causes of construction conflict. They are: (i) weak project leadership (ii) weak contractor selection (iii) weak project management, and (iv) project participants' attitude.

The purpose of this study was to understand how participants' experiences of participating in self-sufficiency projects were. To do this, we analyzed phenomenological methods using in-depth interview data of 48 participants from the Central Self-Sufficiency Foundation, which is qualitative data of the "Project for Strengthening Self-Support for the Working Poor". The study revealed 214 meaningful statements and general re-statements, 24 themes, 9 themes cluster, and 5 categories. Participants' experience was found to be forced work, felt alienated from the self-sufficiency business, and could not receive a clear vision for the future. At the same time, the experience of participating is an opportunity for motivation for change in one's own life, and the essence of becoming a stepping stone to move forward for self-reliance has been derived. Based on the results of this study, we proposed a practical policy task to create a positive expectation effect.

Along the information technology progresses, the demand for the educational application increases which derives the need for cyber education. Cyber education should take the knowledge construction model rather than the knowledge delivery model. For the educational paradigm shift by cyber education, 'Project-Based Learning' and 'Cyber Learning Community' need to be adopted. In this study, project-based cyber learning community for teacher education is developed with 5 major categories: Home(community vision, general information, project list, Q&A), project learning center(preparation for the instructional activities, group-based learning activities, presentations), meeting plaza(request for group mentoring, sharing ideas, meeting specialist, survey participating, forum participating, result presentation), references(cases of project studies, materials for project studies, materials for teacher education, general materials), management(project management, project cases, idea bank, finding partners, dialog with instructors, sharing references, sharing experiences, survey, forum).

The purpose of this study is to find out how those taking early childhood preservice teachers experience their learning through learner-centered education and the meaning given by such experiences to grasp their values. Especially, to look into experiences of learning the project approach theory studied and directly experienced, which is one of the early childhood educational approach methods, data on participatory observation, personal interviews, personal reflective journals, activity reports and ect. were collected and analyzed by the current writer, who fully participated in the class. The meaning of early childhood preservice teacher'experiences in the project approach was analyzed from the two aspects of 'my' learning activities and 'teacher's teaching activities. In the aspect of 'my' learning activities, they got indulged through purposeful practices in the process of tackling problems that originated from personal interest and wanted to share the joy of learning they'd had with others. Aware of themselves as doers of behavior and thinking, they were found to be able to focus an 'my' own learning activities based on these learning experiences of theirs. In the aspect of 'teacher's teaching activities, project theories and practices done at the same time helped them internalize the project and they learned possible changes ign the project by experiencing actual cases. To sum up, the project approach has its meaning in that it not only helps teachers learn theoretical knowledge but also have reflective thinking through their experiences as doers of learning and form practical knowledge. Accordingly, it indicates th need for intensive discussion on the project approach as a way to educate pre-teachers or current ones.
