정부는 선진외국을 중심으로 진행되고 있는 CALS의 개념을 국내 건설산업에 적용하여 건설산업의 선진화 및 국가경쟁력을 확보하고자 건설CALS의 핵심부분인 CITIS체계 개발에 노력을 기울이고 있다. 그러나, 아직 가상헙업공간으로서의 기능이 부족하고 현장 적용을 통한 기능개선 띤 기반확산 노력이 미흡한 실정이다. 본 연구의 목적은 건설 CITIS체계의 지속적인 적용을 위한 기반조성 띤 성능개선을 위한 시도로서 프로젝트 참가자간의 정보교류 및 협업을 지원하기 위한 가상기업 개념을 정립하고 이에 기반한 CITIS 개선모델을 제안하는데 있다. 이를 위해, 일선 도로건설현장을 대상으로 실증시험 사업을 수행하여 건설 CITIS의 효과를 검증하고 가상기업으로서의 CITIS가 갖추어아 할 시스템 성능개선 방안을 도출하였다.

With the rapid development of the Chinese water project, the safety monitoring of dams is urgently needed. Many drawbacks exist in dams, such as high monitoring costs, a limited equipment service life, long-term monitoring difficulties. MEMS sensors have the advantages of low cost, high precision, easy installation, and simplicity, so they have broad application prospects in engineering measurements. This paper designs intelligent monitoring based on the collaborative measurement of dual MEMS sensors. The system first determines the endpoint coordinates of the sensor array by the coordinate transformation relationship in the monitoring system and then obtains the dam settlement according to the endpoint coordinates. Next, this paper proposes a dual-MEMS sensor collaborative measurement algorithm that builds a mathematical model of the dual-sensor measurement. The monitoring system realizes mutual compensation between sensor measurement data by calculating the motion constraint matrix between the two sensors. Compared with the single-sensor measurement, the dual-sensor measurement algorithm is more accurate and can improve the reliability of long-term monitoring data. Finally, the experimental results show that the dam subsidence monitoring system proposed in this paper fully meets the engineering monitoring accuracy needs, and the dual-sensor collaborative measurement system is more stable than the single-sensor monitoring system.

Integrated Project Delivery (IPD) as a delivery method fully capitalizes on an integrated project team that takes advantage of the knowledge of all team members to maximize project outcomes. IPD is currently the highest form of collaboration available because all three core project stakeholders, owner, designer and contractor, are aligned to the same purpose. Compared with traditional project delivery approaches such as Design-Bid-Build (DBB), Design-Build (DB), and CM at-Risk, IPD is distinguished in that it eliminates the adversarial nature of the business by encouraging transparency, open communication, honesty and collaboration among all project stakeholders. The team appropriately shares the project risk and reward. Sharing reward is easy, while it is hard to fairly share a failure. So the compensation structure and the contingency in IPD are very different from those in traditional delivery methods and they are expected to encourage motivation, inspiration and creativity of all project stakeholders to achieve project success. This paper investigates the compensation structure in IPD and provides a method to determine the proper level of contingency allocation to reduce the risk of cost overrun. It also proposes a method in which contingency could be used as a functional monetary incentive when established to produce the desired level of collaboration in IPD. Based on the compensation structure scenario discovered, a probabilistic contingency calculation model was created by evaluating the random nature of changes and various risk drivers. The model can be used by the IPD team to forecast the probability of the cost overrun and equip the IPD team with confidence to really enjoy the benefits of collaborative team work.

본 논문은 세계 여러나라의 대학들이 다학제간 자동차 개발 프로젝트를 공동으로 수행함으로써 혁신적 공학교육 환경을 구축하기 위한 노력을 기술하였다. 이 프로젝트의 주 목적은 학생들로 하여금 신속한 설계와 제조에 대한 실질적 경험을 갖도록 하는 동시에 국제적 규모의 협업을 통하여 다른 국가의 다른 전공의 학생들과 의사전달 경험을 쌓도록 하는 것이다. 이를 위해서 먼저 산업디자인 전공학생과 공학전공 학생들간에 긴밀한 협조환경을 강조하였으며 이는 프로젝트에 있어서 설계와 제조간의 공조의 어려움 뿐만 아니라 서로 다른 전공의 특히다른 국가의 대학들의 학생들끼리 스스로 프로젝트 팀을 구성하고 분업하여 효율적으로 협업을 이루어 가야 한다는 점에서 중요한 교육적 시도임을 시사하였다. 또한 향후 각 대학에서는 지속적인 의사전달기술을 토대로 팀기반 협업환경에서의 설계교육을 강화하여 국제적 공학혁신 교육환경을 조성하기 위한 노력이 중요하다는 점을 제시하였다.

Cyberinfrastructure is a research infrastructure that provides an environment in which research communities can get access to distributed resources and collaborate at unprecedented levels of computation, storage, and network capacity. The Worldwide LHC Computing Grid (WLCG) is a global collaborative project of computing or data centers that enables access to scientific data generated by the Large Hadron Collider (LHC) experiments at CERN. This case study analyzes the WLCG as a model of cyberinfrastructure in research collaboration. WLCG provides a useful case of how cyberinfrastructure can work in providing an infrastructure for collaborative researches under data-intensive paradigm. Cyberinfrastructure plays the critical role of facilitating collaboration of diverse and widely separated communities of researchers. Data-intensive science requires new strategies for research support and significant development of cyberinfrastructure. The sustainability of WLCG depends on the resources of partner organizations and virtual organizations at international levels, essential for research collaboration.

The use of computers in architectural professions has grown with the power of easy data management, increased sophistication of standalone applications, inexpensive hardware, improved speed of processing, use of standard library and tools for communication and collaboration. Recently, there has been a growing interest in distributed CAAD (Computer-Aided Architectural Design) integration due to the needs of direct collaboration among project participants in different locations, and Internet is becoming the optimal tool for collaboration among participants in architectural design and construction projects. The aim of this research is to provide a new paradigm for a CAAD system by combining research on integrated CAAD applications with recent collaboration technologies. To accomplish this research objective, interactive three-dimensional (3D) design tools and applications running on the Web have been developed for an Internet-based distributed CAAD application system, specifically designed to meet the requirements of the architectural design process. To this end, two different scopes of implementation are evaluated: first, global architecture and the functionality of a distributed CAAD system; and, second, the association of an architectural application to the system.

Collaborative product commerce (CPC) is a newly emerging technology to support inter-enterprise collaboration through the product life-cycle. From the IT point of view, CPC is software technology to integrate product, process and resources of different enterprises using Web technologies. In this paper, we introduce a CPC framework for integrating product information across enterprises, which being developed as a part of the CPC project by ETRI. The product metadata represented by XML schema, which is compatible with ISO STEP PDM Schema standard, is presented to semantically and schematically integrate distributed product information. The web services technologies are discussed to support the interoperability of application systems related to the product development, such as CAD and PDM, where most of these applications run in a distributed environment. Finally, we implement the frame-work to integrate distributed product information.

This project aims to develop a partnership between France and Korea; the field of paper conservation with two mains objectives. The first object is to study the possibilities of implementing the use of traditional Korean paper in conservation workshops in France and Europe. The second one is to establish a long term collaborative research program to investigate the degradation mechanisms of ancient papers and particularly early waxed manuscripts founded in Korea and France which are now brittle and fallen into parts. This problem deserves an investigation using analytical tools such as SEC/MALS, GC/MS to understand the interactions between wax and cellulose during the ageing process and to recommend proper conservation treatment. A research plan could be establish for both institution in order to facilities an exchange of visiting scholars (scientist, post-doc) to implement and share knowledge and for carrying out the research.
