Recently, the government has provided support such as entering new markets, expanding sales channels, and supporting manpower, not just in the form of funding, to efficiently and effectively support limited national resources to improve corporate performance. In this study, we tried to find out the effect of government support for companies that have benefited from the Excellent Technology Research Center Project (ATC Project) and the World Class 300 project using propensity score matching. As a result of the analysis, the effect of government support for the ATC project became visible after the appointment period, while the effect of the World Class 300 project was insignificant. This means that when the size of the company is small, the effect of government support is more pronounced. This suggests that in order to maximize the effectiveness of government support, appropriate national policy interventions such as government innovation funding are needed when the size of the company is small. In this study, differences in the timing, performance indicators, and company size of policy support effects were found in the growth stage of a company from a mid- to long-term time series perspective, suggesting that support policies based on this need to be adjusted and redesigned.

건설 프로젝트의 효과적인 물류 및 진도관리를 위하여 다양한 연구 및 시도가 이루어지고 있다. 이중 RFID+4D 기술은 철골, PC, 커튼월과 같은 공장 주문형 자재의 공급망 및 진도관리를 위해 개발된 기술로써 공기 및 비용 절감에 대한 효과가 있는 시스템으로 보고된 바 있다. 하지만 기존의 시스템은 그 효과에 비해 모델링 비용, 실시간 정보 반영의 난이, 시스템 운영을 위한 추가 인력 배치 등의 문제로 인해 시스템 확산이 미비한 상태에 있다. 따라서 본 연구에서는 이러한 기존 RFID+4D 프로세스의 문제를 해결하기 위한 체계 및 제안된 체계를 활용한 웹 기반의 실시간 4D 시뮬레이터를 개발하였다. 본 연구에서 개발된 체계 및 시스템은 기존 RFID+4D 프로세스 운영의 비용 및 정보 활용성을 향상시킴으로써 기술 확산에 기여할 것으로 기대되며 특히 최근 이슈화되고 있는 BIM 정보와의 연계를 통해 설계 단계에서 생성된 BIM을 시공 단계에서 활용하기 위한 방법으로 활용 가능할 것으로 판단된다.

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.

This study aims at the development of a cost management system in building interior projects. Renovation and remodeling is activated and expanded much more being compared with new building construction at present. After Interior project proceeding must get out of simple estimate and assumption, then its be needed a formal work process and computerized cost management. Proceeding a building interior project management was proceed in the office and the field. Cost break down, especially, depend on the field manger and used fiend managing money because its not checked by cost manager in office manger. For this study, cost factors are defined in terms of cost break-down interior works which consist of materials and labors. A data model for cost factors was developed, and a relational database is used to realize cost data management based upon this data model. Data input and output are achieved by internet from both of wired PC and mobile phone. This system can timely display a number of needed reports for cost management that identifies cash flow and predicts budget for cost break-down works in interior projects.

Taliesin West is a meaningful historic site in architecture field, because its place had still been existing only one in the world as a ideal architectural community for working and living as well as learning by doing for Taliesin Fellowships and others based on F. L. Wright's idea of Organic Architecture. The main purpose of this study was to follow up the architectural thought and its construction shown in F. L. Wright's 'Taliesin West'. A study on the key notes are as follows; 1) The key-clue of the construction background for Taliesin West was based on the project of 'Complex Campus Building' which was early planed by F. L. Wright. 2) A basic design idea for Taliesin West was admiring from its own site characters as well as the Experimental construction methods and materials. 3) Design motive of Taliesin West was based on American Indian's movable shelter which called 'Tepee.' 4) A construction of F. L. Wright's temporary studio, Ocotilla, was a good opportunity to construct for Taliesin West which construction methods, covered and framed, were same as Ocotilla. 5) A concept idea of the master plan for Taliesin West came from combining Taliesin's Hillside Home School and Complex Campus Building project. 6) Construction of Taliesin West was a final accomplished place as F. L. Wright's utopia architecture and community.

In this paper, a composite material analysis program based on the finite element method(FEM) is used. The purpose of this study was to verify whether the composite material analysis program which developed as part of a project of development of softwares and educational contents for structural vibration and composite material analysis that can calculate how similar the macroscopic mechanical behavior of the composite materials actually. Because composite materials are generally anisotropic, analysis of composite laminate is used for the constitutive equations of orthotropic material. For convenience, the unit is ommited in all calculations. To verify the accuracy of the finite element method based program, the deflection and stress distribution of the simply supported composite material laminated plate subjected to a uniform load distribution is compared with exact solution. Size and properties of the composite material laminate used for analysis are fixed variables, and by changing the number of elements and the total thickness of the laminate is compared with the exact solution to the resulting value, respectively.

Today's construction is higher and more complex. So types and amounts of needed materials for construction project are increasing and those are occurred problems in construction site such as insufficient working space, confusion of materials handling order and working circulation. Because of those problems, research of progress management system using RFID+4D has been studied, but it is impossible to manage progress and material statement in real-time. So this study analyzed problems of current research and suggested VRML based RFID+4D Progress Management System. This Study focused on system basic concept and interface is designed for system development. This research is still progressing, so it has to do more development and research. However, it could be expected construction management efficiency and automation of management tasks.

The objective of this research project was to develop the wooden footpath block to reuse of wood waste. Some physical and mechanical properties of the wooden block such as water absorption, thickness swelling, modulus of rupture, internal bond, density profile and impact resistance were studied. Water absorption and thickness swelling of the wooden block were greatly reduced when the wooden block was pressed inside the forming device than by conventional hot pressing. Also, Modulus of rupture and internal bond of the wooden block were increased greatly when the pressing was completed inside the forming device. The density profile of the wooden block was improved up to 93.5%, minimum to average density ratio. The wooden block manufactured in this study have excellent physical and mechanical prperties in comparison with existing wood based materials. So, these wooden blocks are applicable to footpth block or other exterior members.

Adaptive neuro-fuzzy inference systems (ANFIS) can be efficient in modelling non-linear, complex and ambiguous behavior of cement-based materials undergoing combined damage factors of different forms (physical and chemical). The current work investigates the use of ANFIS to model the behavior (time of failure (TF)) of a wide range of concrete mixtures made with different types of cement (ordinary and portland limestone cement (PLC)) without or with supplementary cementitious materials (SCMs: fly ash and nanosilica) under various exposure regimes with the most widely used chloride-based de-icing salts (individual and combined). The results show that predictions of the ANFIS model were rational and accurate, with marginal errors not exceeding 3%. In addition, sensitivity analyses of physical penetrability (magnitude of intruding chloride) of concrete, amount of aluminate and interground limestone in cement and content of portlandite in the binder showed that the predictive trends of the model had good agreement with experimental results. Thus, this model may be reliably used to project the deterioration of customized concrete mixtures exposed to such aggressive conditions.
