우리나라의 국가연구개발사업 투자규모와 연구성과의 양적수준은 증가하고 있으나, 성과활용 실적은 저조한 상황이다. 따라서 국가연구개발사업의 사업화에 영향을 미치는 요인에 관한 체계적인 파악과 분석은 매우 중요하다. 다만 선행연구들은 객관적인 데이터기반의 분석이 아닌, 주로 질적 연구를 중심으로 이루어져왔고, R&D투입요소와 산출물 간의 영향요인을 분석하는데 집중되어 왔다. 이에 본 연구에서는 부품소재산업경쟁력향상사업을 사례로 하여 국가연구개발사업의 연구성과, 연구주체유형, 정부지원규모, 과제유형, 연구자의 역량, 기술분야가 사업화에 미치는 영향에 대하여 객관적인 데이터를 기반으로 체계적으로 분석하고자 하였다. 분석결과, 특허성과와 정부지원규모, 기술분야 등의 요인들이 사업화성과에 영향을 미치는 것으로 나타난 반면, 논문성과와 연구수행주체유형, 과제유형, 연구자의 과제수행능력은 통계적으로 유의한 결과를 드러내지 못하였다. 따라서 향후 부품소재산업경쟁력 향상사업을 포함하여 국가R&D사업의 과제기획, 추진과정, 과제평가 등에서 사업화성과를 높이기 위해서는 투입과 결과 간의 인과관계를 보다 분석적으로 파악하여 과학적인 연구개발프로젝트 설계를 시도해야 할 것으로 판단된다.

Reward-based crowdfunding is a funding platform that allows funds to be raised to early operators who have lack of funds, and is seen as an outstanding infrastructure that is going to lead the fourth industrial revolution in that it is a field of realization of new technologies and creative ideas by start-ups. Reward-based crowdfunding has grown in line with the trend of the fourth industrial revolution, and funding success cases are taking place in various industries that culture/art to technology/IT, including as a new means of knowledge management in a rapidly changing industrial environment. The study focused on the fact that consumer's donation purposes may also vary depending on the category of projects classified as reward-based crowdfunding. Because consumer payment decisions and motivation of consumer purchasing behavior are classified according to the purpose of purchase, the previous papers that the goal gradient effect that the main motivation of consumer donation for reward-based crowdfunding introduced vary depending on project category of utilitarian and hedonic. In this study, consumer's daily donation data is collected by Indiegogo which is a leading reward-based crowdfunding company using web-crawling and the model was defined as propensity score matching (PSM) and random effect model. The results showed that the goal gradient effect occurred in utilitarian project category, but no goal gradient effect for the hedonic project category. Furthermore, this paper developed the study of motivation of consumer donation and contributes theoretical foundation by the results consumer donation may vary depending on the project category; also, this paper has implications for an effective marketing strategy depending on the project category leaves real meaning to the projector.

The offshore installation units may be subjected to various accidental loads such as collision from supply vessels, impact from dropped objects, blast load from gas explosion and thermal load from fire. This paper deals with the design and strength evaluation method of the stiffened plate structures in response to a blast load caused by a gas explosion accident. It is a comprehensive review of various items used in actual project such as the size and type of the explosive loads, general design procedure/concept and analysis method. The structural analyses using simple analysis methods based on SDOF model and nonlinear finite element analysis are applied to the particular FPSO project. Also validation studies on the design guidance given by simple analysis method based on SDOF model have also considered several items such as backpressure effects, material behavior and duration time of the overpressure. A good correlation between the prediction made by simple analysis method based on SDOF model and nonlinear finite element analysis can be generally obtained up to the elastic limit.

Compared with other industries, the construction Industry has many parties(A/E/C) as well as many types of construction activities. Especially, as for the remodeling project, the owner group the remodeling union consists of various stakeholders union and requiring the additional activities of demolition except for the existing new building construction project. Like this, the remodeling project has its own characteristics different from a new building construction project. As for the remodeling project, the Owner's decision making for a remodeling alternative has to be preceded, and other parties are required to propose a remodeling alternative which satisfies the Owner's requirements. However, because of time constraints, many types of problems occur during the decision-making process. In consideration of this, in this research, the authors would like to suggest a decision-making support system to help the Owner's decision-making in the early stage of a remodeling project. For this paper purpose of a remodeling decision-making framework based on Building Information Modeling(BIM) was suggested to help with the Owner's decision-making for each remodeling item and the decision-making support system was evaluated through Case Study.

In this paper, we'd like to briefly introduce Korean common speech database, which project has been started to construct a large scaled speech database since 2002. The project aims at supporting the R&D environment of the speech technology for industries. It encourages domestic speech industries and activates speech technology domestic market. In the first year, the resulting common speech database consists of 25 kinds of databases considering various recording conditions such as telephone, PC, VoIP etc. The speech database will be widely used for speech recognition, speech synthesis, and speaker identification. On the other hand, although the database was originally corrected by manual, still it retains unknown errors and human errors. So, in order to minimize the errors in the database, we tried to find the errors based on the recognition errors and classify several kinds of errors. To be more effective than typical recognition technique, we will develop the automatic error detection method. In the future, we will try to construct new databases reflecting the needs of companies and universities.

최근 건설 프로젝트가 대형화 복잡화됨에 따라 단일 프로젝트의 건설 사업비 규모가 증가하는 반면 IT 산업의 발달과 더불어 건설현장에서 발생하는 다양한 자료 축적이 쉬워지고 있다. 따라서 건설공사 라이프싸이클 관점에서 축적된 실적 데이터를 활용하여 생산성을 향상시키기 위한 연구가 활발히 진행 중이다. 최근 건설사업관리를 위해서 많이 사용하고 있는 PMIS(Project Management Information System)는 시공단계에서 데이터의 축적과 활용에 많은 편리함을 준다. 그러나 대부분의 PMIS는 시공단계에 제한되어 있으며 기획, 설계 및 유지관리의 단계까지는 적용되지 않고 있는 실정이다. 본 논문에서는 기획, 설계, 시공, 유지보수 단계까지 관리를 위한 효율적인 하나의 방안으로 BIM(Building Information Modeling) 기반의 PMIS인 BPMS(BIM-based Project Management System)를 제시한다. BPMS는 대상물의 설계 및 시공정보를 포함하여 건설 생애주기 관점에서 사업관리를 지원하고자 개발되고 있다.
