We report on our experience on utilization of collaborative tools for KISTI high energy physics group. Our main subject will be the new EVO (Enabling Virtual Organization) server that we hosted recently at KISTI. The EVO is a next generation collaborative tool from CalTech high energy physics group with several improvements from its predecessor VRVS (Virtual Room Videoconferencing System). EVO has the same baseline structure as in VRVS. The network of servers lies at the heart of EVO structure and one server called Panda communicates with local clients called Koala.

In this paper, we propose a model of the collaborative authoring tool and its implementation results. In the 'collaborative authoring and automatic distribution system,' users can create eBooks by using partial works (primary and edited sources) on the basis of copyright information registered by the primary author. The Collaborative Authoring Tool is a part of "the collaborative authoring and automatic distribution system" developed through research on "the development of key technologies of social work protection and content mashup tools" as an R&D project granted by the Korea Copyright Commission from 2013. In the collaborative authoring and automatic distribution system, authors of primary sources such as images, audio clips and video clips for eBooks can register them together with the copyright information; users can edit the primary sources to produce secondary sources and in turn register the secondary sources on the system; and users can create and distribute eBooks by using the sources registered in the system.

In this paper, the design result of robotic tools and the development of robot control system for chemical coupler assembly are presented. This research aims to eliminate the risk of chemicals exposed to human operators by developing the robotic tools and robot automation system for chemical tank lorry unloading that were done manually. Due to tight tolerance between couplers, even small pose error may result in very large internal force. In order to resolve the problem, the 6-axis compliance device is employed, which can provide not only enough compliance between couplers but also F/T sensing. The 6-axis compliance device having large force and moment capacity is designed. A simple linear gripper with rack-and-pinion is designed to grasp two sizes of couplers. The proposed robot automation system consists of 6-DOF collaborative robot with offset wrist, 6-axis compliance device with F/T sensing, linear gripper, and two robot visions.

Traditional business process management systems provide verification tools of process models to deploy and automate the models. However, there are not so many studies on how to maintain systematically collaborative process models such as supply chain processes when companies are willing to change and update the collaborative process models. In this paper, we analyze change patterns of collaborative processes and declare 19 change patterns. In addition, we apply the change patterns to the process interoperability patterns in order to identify the change problems in case of independent process changes of collaborative processes. As a result, we devise an independency checking algorithm of process changes in collaborative processes.

The objective of this article is to create a model of integrated management from the framework modeling of a digital collaborative network supported by knowledge engineering to make heritage site in the Brazil more effective. It is an exploratory and qualitative research with thematic analysis as technique of data analysis from the collaborative network, digital platform, world heritage, and tourism themes. The snowballing approach was chosen, and the mapping and classification of relevant studies was developed with the use of the spreadsheet tool and the Mendeley® software. The results show that the collaborative network model oriented towards strategic objectives should be supported by a digital platform that provides a technological environment that adds functionalities and digital platform services with the integration of knowledge engineering techniques and tools, enabling the discovery and sharing of knowledge in the collaborative network.

협동학습이 효과적으로 이루어지기 위해 가장 중요한 요소는 학습자의 여러 특성을 고려한 모둠 구성에 있다. 모둠 구성이란 원활하게 협동학습을 진행하기 위해 학습자들을 다양한 특성에 근거하여 모둠을 구성하는 것이다. 잘못된 도구의 선정으로 인해 모둠의 구성이 제대로 이루어지지 않을 경우 학생들의 불만이 수업으로 이어져 학습의 효과로까지 나타나는 문제가 발생할 수 있다. 본 논문에서는 학습효과 향상 및 불링 경향성 진단을 함께 고려한 모둠 구성 도구를 구현하였다. 소시오메트리 설문을 통한 학생들 간의 학급선호도와 학생의 성적을 입력받아 교사의 주관에 맞게 모둠을 구성함으로써 학습 효과도 고려할 수 있고 더불어 불링 경향성도 진단할 수 있는 모둠 구성 도구를 제안하고자 한다. 이를 통해 교사는 학습 효과를 증진 시킬 수 있는 수업 진행이 가능한 협동학습뿐만 아니라 학생들의 교우관계를 미리 파악해 학급 내에서 일어날 수 있는 불링에 미리 대처할 수 있을 것으로 기대한다.

The information technology of computers and computer tools have become so powerful that virtual enterprises are not just concepts any longer The virtual enterprises comprise distributed facilities and it is necessary to have a collaborative system among them. This paper proposes the modeling process of web-based collaborative system in the distributed manufacturing environment. It also presents the information infrastructure in order to communicate and to share the information more efficiently among the collaboration subsystem. The web-based collaborative system consists of four processes: 1) product design, 2) procurement of DB information, 3) query process, and 4) negotiation. The proposed web-based collaborative system will be implemented with network technologies.

The mobile application market has been growing extensively in recent years. Currently, Apple's App Store has more than 400,000 applications and Google's Android Market has above 150,000 applications. Such growth in volumes of mobile applications has created a need to develop a recommender system that assists the users to take the right choice, when searching for a mobile application. In this paper, we study the recommendation system building tools based on collaborative filtering. Specifically, we present a study on comparison analysis of collaborative filtering in Java and R statistical software. We implement the collaborative filtering using Java's Apache Mahout and R's recommenderlab package. We evaluate both methods and describe the advantages and disadvantages of using them in order to implement collaborative filtering.

본 연구는 가상 환경에서의 협력 학습에의 참여가 학생들의 학업 성취도와 만족도에 미치는 영향을 조사하고자 하였다. 세컨드라이프라는 가상현실 플랫폼에 고등학생이 국사 과목을 학습할 수 있는 공간을 만들고 이를 활용하였다. 총 119명의 참가자를 '협력학습 유형'이나 '개인학습 유형'에 무선 할당하였으며, 학생들의 학업 성취도와 만족도를 측정 도구로 수집하였다. 가상공간에서의 협력학습의 효과를 검토하려 독립표본 t검증 및 대응표본 t검증을 실행하였고, 연구의 결과는 개인학습 유형에 참여한 경우보다 협력학습 유형에 참여한 경우가 학업성취도와 만족도에 유의미하게 긍정적 영향을 미치는 것으로 나타났다. 마지막으로 향후 가상현실을 기반으로 한 협력학습의 활용에 대한 제언이 논의되었다.

Supply chain management is a practical vision of industrial information systems in the global competitive environments. In these environments, the linkage of business processes between enterprises which compose a supply chain should be constructed. In this study, we designed and developed supply chain management tools to provide collaborations between enterprises. The developed tools are designed to act as a coordinator for the suppliers and consumers in the supply chain.
