As recent multilateral collaboration design system has been advanced, BIM based data exchange is a key factor for successful next generation building project. Even though many studies have been trying to set up a data compatibility system for collaboration, There are still a lot of problem in data exchange between design and engineering phase. Therefore, In this study, we analysis causes of problem for information exchange and suggest a IFC based Information exchange framework for improving BIM based design collaboration environment. In order to find out problems that hinder establishment of advanced open BIM information exchange, proper analysis about transition of process from current and to-be BIM based design collaboration process is important, at first. From analysis of main obstacles to information exchange, this research suggests solution plan using open API and IFC based BIM collaboration supporting system. The suggested open API solution named Integrity feedback system perform a role making up for weak point derived from IFC based data exchange. And main system suggestion about framework for IFC based information exchange reflect technological system support, requirement of function for collaboration including API/BCF plug-in.

As entering the international construction market became more difficult than the past, ODA projects can be a breakthrough for domestic engineering companies to enter the international market. However, since many companies compete for limited projects, it is necessary to reinforce the competitiveness of bidding success. The competitiveness is the result of accumulating experience, reputation, and networking through partnering. Therefore, depending on which partnering strategy has been taken over a long period, the bidding success is decided. The objective of this study is to identify the effective partnering strategy for bidding success. For this, the World Bank bid results, focusing on consulting projects in Vietnam, are collected. Using the bid results, inter-firm network representing the partnering relationship is constructed and the Social Network Analysis is conducted. After then, by conducting the Logistic Regression Analysis, effective partnering strategies are suggested. The result shows that the diversification strategy is advantageous for transportation and city development projects and the concentration strategy is advantageous for water projects. The partnering strategy for the consulting project proposed in this study will be used as a reference for the domestic engineering companies to enter the Vietnam construction market in the future.

The epidemic of COVID19 caused a big change in design collaboration, which has been conducting using face-to-face interaction. Designers actively used video conferencing and online document tools in situations where face-to-face meetings were difficult, and this gave them an opportunity to experience that non-face-to-face collaboration can be more effective in a specific design process. In this regard, this study attempted to find out which activities during the design process are more compelling in face-to-face collaboration or non-face-to-face collaboration. To do this, three user experience design projects conducted after the COVID19 epidemic were analyzed through a retrospective interview method. As a result, during four design stages, 'Discover, Define, Develop, Deliver', face-to-face collaboration is necessary for the areas that require creative problem solving through active interaction. In contrast, non-face-to-face collaboration is preferred and more effective when designers need their own space and proceed their design work. In addition, the aspects of design tools supporting non-face-to-face collaboration were also illustrated. Findings discovered through this study are expected to contribute to research on the design process later.

A workflow procedure has recently become more complicated and large scaled. In this paper, we propose an advanced workflow modeling methodology, called a fragment driven cooperative workflow modeling methodology. which enables several real workflow designers to cooperatively define a workflow model. The methodology is a Bottom-Up approach in terms of integrating a set of fragment ICNs to compose a complete workflow model. Each fragment ICN is defined by each participant in the cooperative modeling session, We also use the ICN based formal description and the ICN based graphical notation as well. Finally, we prove the feasibility of the methodology by implementing a cooperative workflow modeling system.

Intelligence of collaborative environments starts from a trial to provide optimal services to with users based on real-time information about participants and environments of the collaboration itself. Up to now, we can collect information such as temperature, light, time, each participant's gestures, faces, voices, and locations by adopting ubiquitous computing technologies. However, since social relationship is intrinsic to collaborative activities, the relationships and roles among participants should be fully considered to provide optimal services. To do so, we have to integrate collected data from various sensors and extracted data about relationships and roles among participants as unified one context. Thus, this paper designs collaborative services filtered, by using the integrated data as a context, and introduces an implemented example, context-aware based interactive display service, called as smart meeting system (SMeet system).

An information system in a construction project has been typically used for drawing, document management, and administration process. And it has limitations to support real-time communication and collaboration among project stakeholders. The objective of this research is to improve communication, information share, and task management by developing a collaboration platform among project stakeholders supporting various communication methods and contents. The platform developed in this research, named as CCP, aims to support communication and collaboration related activities beyond the scope of legacy systems at construction sites. CCP was validated through pilot test and user survey, and it was found to be very helpful for sharing and distributing information, tracking and recording, and improving a user's work capability.

In this paper, we describes a Compact Distributed Object Group Framework(CDOGF) for mobile collaboration service in ubiquitous computing. CDOGF support network connections of sensors and devices, management of mobile computing devices, and grouping of objects for mobile collaboration service according to the logical area. For this, we defined methods for detail functions and interface. And, we classified into four interactions of that sensors and a application, the CDOGF and a application, between the components of the CDOGF, the CDOGF on a mobile device and the DOGF on a server. We also defined mobile collaboration environment by analyzing existing technologies. In this environment we used the TMO scheme for interaction and the TMOSM for distributed middleware. Finally, we implemented u-hospital application that applied this environment. This application collects environment and health information by PDAs in wards. Also, It provides the information service for patient management task.

As construction projects are complicated and large in scale, a collaboration between project participants is getting more emphasized over the last few years. The collaboration tools for participants are various. but traditionally drawings and specifications have played an important role. Especially, though storage form in drawings vary in entire construction lifecycle, drawings are still important as the core factor in latest information technology streams in regard to usefulness and reusability of information. As an attempt to standardize drawings in the public construction based on CALS/EC, this study analyzes user's requirements for drawings qualitatively, and looks into drawings standards in Korea, America and Japan, and each kind of ISO standard for drawings. And this study predicts future-oriented user's requirement for drawings based on Construction CALS/EC, and presents future-oriented direction of development applicable in domestic drawing standard in construction.

The current study explored if users' self-relevance of the comparison domain with creative AI robot in music composition affected their envy toward the robot, cognitive assessment toward the music and intention toward working with robot in future. This study conducted a 2 (degree of self-relevance: high(college students majoring in music) vs. low(those not majoring in music) × 2 (working type: robot-only vs. robot-human collaboration) between-subjects factorial design experiment. The findings revealed that those majoring in music did not feel envious of the robot as much as those not majoring in music. However, compared to those not majoring in music, those majoring in music evaluated the robot's creativity lower, had more negative attitude toward the music, showed less intention to use the music and work with the robots in future. No interaction between the degree of self-relevance and the working type was found.
