This paper explores the ways in which collaborative working among multiple disciplines in building projects can be more effective and efficient. It focuses on the support that can be provided by the latest development in information and communication technologies. It also considers the growing interdependence between participants in the process and their changing roles as they harness the power of the new technologies in new collaborative arrangements. It is argued that collaborative working should be addressed holistically from the technological angle, the social angle, as well as the organisational angle, to ensure its successful implementation in the construction industry. A case study is given to illustrate the use of ICT in supporting value management studies. The key issues surrounding the emerging field of research - collaborative construction information management - and the potential benefits and challenges of its wide adoption are discussed at depth.

The world wide web (WWW) already accounts f3r more Internee network traffic than any other application, including il and simple file transfer. It is also a collaborative technology in a weak sense of the word - it allows people to share information. Synchronous collaboration is where an interactive activity is simultaneous and in teal-time. Computer based real time collaborative systems like shared whiteboards. collaborative editor etc. are only beginning to emerge recently. These applications invoking more than two users exchanging information, require Multicast communication. Multicast communication is a transmission mode that is now supported by a variety of local and wide area networks. Multicasting enables multiparty communication across a wide area to sparsely distributed groups by minimizing the network load. Multicasting itself is one of the key technologies in the nut generation of the Internet This paper describes the technical issues from the aspect of multicast communication and its reliability in synchronous collaborative application.

In this paper, we propose a method for diagnosing overload and working load of collaborative robots through performance analysis of machine learning algorithms. To this end, an experiment was conducted to perform pick & place operation while changing the payload weight of a cooperative robot with a payload capacity of 10 kg. In this experiment, motor torque, position, and speed data generated from the robot controller were collected, and as a result of t-test and f-test, different characteristics were found for each weight based on a payload of 10 kg. In addition, to predict overload and working load from the collected data, machine learning algorithms such as Neural Network, Decision Tree, Random Forest, and Gradient Boosting models were used for experiments. As a result of the experiment, the neural network with more than 99.6% of explanatory power showed the best performance in prediction and classification. The practical contribution of the proposed study is that it suggests a method to collect data required for analysis from the robot without attaching additional sensors to the collaborative robot and the usefulness of a machine learning algorithm for diagnosing robot overload and working load.

Collaborative product commerce(CPC) involves many people working together with heterogeneous and distributed software applications. For such an environment, Workflow Management System(WFMS) can be useful for coordination of people, software agents and processes. It provides diverse services including automatic work muting, project management continuous process improvement and application integration. However, there are some limitations to apply WFMS to CPC environment due to inflexibility and lack of design support facilities. This paper identifies the problems and addresses possible approaches to overcome the difficulties.

Since customer's demand is various and product life cycle is getting shorter, many manufacturing company is trying to reduce product development time and cost. For that reason they make an effort to design product on collaborative environment. The various activities in a product development are highly distributed. This distributed nature of the activities implies that teams will be working indifferent place and technical environments. Thus at a given time, teams might work on he same product from different perspectives. This will require efficient communication amongst the various individuals and the various softwaretools that are used by them. Therefore, there is a need for a computerized frame work that can support distributed design such that participants from different backgrounds collaborate towards one common goal. This paper presents the architecture of a collaborative design system. It then reports on the study of computerized frame work focused on collaboration for product development.

This study investigated the Oriental medicine knowledge and educational requirement of medical staff working in Oriental-Western collaborative medicine hospitals(except for Oriental and Western medicine doctors) based on the recognition that not only mutual understanding and cooperation between Oriental and Western medicine doctors but also the knowledge of Oriental medicine of medical support staff such as nurses, medical technologists, pharmacists and administrative staff are very important to promote Oriental-Western collaborative medical treatment. The study results are summarized as follows : First, it was found that the ratio of nurses who took Oriental medicine education was much higher than those of other groups. They took Oriental medicine education in the types of school curriculum (27.0%) and special lectures in workplace(20.4%). Second, many of the people who took Oriental medicine education were found to be not satisfied with the education in general - 32.7% of them answered the education content was "so so" and 48.4% of them answered "unsatisfactory." Third, the general necessity of Oriental medicine education was found to be an average of 3.60 out of 5, and the number was higher "after employment"(average=3.85) than "before employment"(average=3.04). Fourth, the study found that Oriental-Western collaborative medicine hospital staff are well aware of the necessity of the knowledge of Oriental medicine in the cases of communications between different occupational types, consultations with patients or their guardians, treatment and nursing and the establishment of the practice of specialized Oriental medicine institutes. Fifth, the levels of Oriental medicine knowledge showed a difference in average value according to the role range(p<0.000), and it was found that there is an interaction effect between occupation type and role range(p<0.015).

From the assumption that an individual's working memory capacity is limited, the cognitive load theory is concerned with providing adequate instructional design so as to avoid overloading the learner's working memory. Based on the cognitive load theory, this study aimed to provide implications for effective problem-based collaborative teaching and learning design by analyzing the level of middle school students' cognitive load which is perceived according to the problem types(short answer type, narrative type, project) in the process of collaborative problem solving in middle school function part. To do this, this study analyzed whether there is a relevant difference in the level of cognitive load for the problem type according to the math achievement level and gender in the process of cooperative problem solving. As a result, there was a relevant difference in the task burden and task difficulty perceived according to the types of problems in both first and second graders in middle schools students. and there was no significant difference in the cognitive effort. In addition, the efficacy of task performance differed between first and second graders. The significance of this study is as follows: in the process of collaborative problem solving learning, which is most frequently used in school classrooms, it examined students' cognitive load according to problem types in various aspects of grade, achievement level, and gender.
