  • This paper aims to construct and analyze the domestic collaborative research network in industrial engineering. Using co-authorship information contained in the papers published in the two journals of the Korean Institute of Industrial Engineers, the collaborate research network at the institutional level is constructed. The core institutions in the network are identified by means of the centrality indexes of social network analysis. In addition, the five types of roles of the institutions in industry-university-institute cooperation are examined through brokerage analysis: coordinator, consultant, gatekeeper, representative, and liaisons. The findings are expected to be fruitfully utilized in formulation of R&D strategy of relevant organizations and technology policy making for promoting collaborative research in industrial engineering.

  • 지식 정보화 시대의 새로운 교육 형태와 패러다임으로 시간과 장소에 구애받지 않고 학습할 수 있으며 학습자 중심 교육을 제공하는 e-러닝에 대한 관심이 고조되고 있다. 그러나 기대에 비해서는 현재까지 e-러닝에 대한 폭발적인 수요와 성장은 발생하지 않고 있는데, 현재 대부분의 e-러닝 교육 형태가 기존의 일방적인 주입식 교육 형태를 단순히 디지털화 하여 학습 콘텐츠의 반복 학습을 제공하는데 그쳐 학습자들의 적극적인 참여와 관심을 이끌어 내는데 실패하였기 때문이다. e-러닝 환경에서 학습자들의 자발적인 참여를 이끌어내고 학습의 몰입도를 높이기 위해 학습 과제를 여러 명의 학생들이 상호 의존하여 공동으로 해결함으로써 학습 목표를 달성하는 형태의 협력학습에 대한 연구가 활발히 진행되고 있다. 본 논문에서는 학습자들 간의 상호작용 을 높이면서 학습행위를 촉진시키기 위한 협력 e-러닝 환경 구축 및 협력학습촉진 에이전트 적용 방안을 제시한다.

  • Purpose - This study primarily aims to represent the current trend of research on CPFR as a promising supply chain collaboration program and proposes a new framework for analyzing any collaboration programs in terms of three key collaborative features. Research design, data, and methodology - This study employs a literature review of selected studies that conduct research on CPFR. CPFR is analyzed based on the proposed framework that characterizes collaboration programs in terms of three key collaborative features. Results - The analysis based on the proposed framework reveals that the current form of CPFR continues to have some collaborative features that are not fully utilized to create an advanced collaboration program. The literature review indicates that most past studies ignore critical issues including the dynamic nature of the multiple-stage supply chain system and negotiation process for collaborative agreement in CPFR implementation. Conclusions - Results indicate that CPFR can become a better supply chain collaboration program by incorporating coordinative cost payment and joint decision making processes. Based on observations on the existing literature of CPFR, this study indicates several important issues to be addressed by future studies.

  • Purpose: This study empirically investigates the effect of collaborative communication and information sharing on the supply chain performance of South Korean pharmaceutical companies. Specifically, it understands the importance collaborative communication and suggests a method for investigating communication in academic research on the pharmaceutical industry. Investigating this sector is crucial because the importance of the pharmaceutical industry is increasing globally against the background of the Covid-19 pandemic. Research design, data, and methodology: A questionnaire was administered to employees of South Korean pharmaceutical companies and 244 valid responses were used for the statistical analysis. Additionally, structural equation modeling was used to measure the relationships between the observed and latent variables. Results: Collaborative communication has a positive effect on information sharing. However, information sharing, unlike collaborative communication, does not exhibit a significant positive relationship with supply chain performance. These results indicate that it is important to communicate effectively in the supply chain rather than strive for the right type of information sharing. Conclusions: Consumers and retailers within the supply chain should continue to strive for candid communication. This study is meaningful, as it empirically tests the relationships between collaborative communication, information sharing, and supply chain performance in the South Korean pharmaceutical industry.

  • To deliver new products to market in a due time, companies often develop their products with numerous partners distributed around the world. Internet technologies can provide a cheap and efficient basis of collaborative product development among distributed partners. This paper provides a framework and its product database model that can support consistent product data during collaborative product development. This framework consists of four components for representing consistent product structure: the product configuration, assembly structure, multiple representations and engineering changes. A product database model realizing the framework is designed and implemented as a system that supports collaborative works in the areas of product design and technical publication. The system enables participating designers and technical publishers to complete their tasks with shared and consistent product data. It also manages the propagation of engineering changes among different representations for individual participants. The Web technologies introduced in this system enable participants to easily access and operate shared product data in a standardized and distributed computing environment.

  • 본 연구는 국내 문헌정보학 분야의 공동연구의 동향을 파악하기 위하여, 26개 대학의 교수업적평가기준 중 공동연구기여도 부분과, 2000년부터 2017년까지 국내 문헌정보학과 교수 195명의 국내외 학술지에 게재된 논문 5,383편의 서지데이터와 키워드 분석을 시행하였다. 그 결과, 첫째. 국내 대학의 교수연구업적평가기준에 따르면 저자는 공동연구에서의 역할과 관계없이 단독연구 보다 낮은 연구업적으로 그 가치를 인정받는다. 둘째. 국내외 논문 게재 추이로 현재 공동연구가 단독연구보다 많은 게재양이 나타나는 것으로 확인되었다. 셋째. 사립대학 소속 저자가 국립대학 소속 저자보다 상대적으로 공동연구 비율이 낮았다. 넷째. 교수직급별 공동연구의 비율의 경우, 부교수가 상대적으로 타 교수 직급에 비해 공동연구 비율이 낮았다. 다섯째. 키워드 분석의 결과로, 국내 공동연구와 국내 연구자가 참여하여 국제학술지에 게재된 국외 공동연구 모두 사회 현상을 반영한 주제 및 신기술을 활용한 정보학관련주제가 두각을 나타냈다.

  • 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.

  • As the educational paradigm has shifted from the traditional knowledge oriented instruction learning to the knowledge product oriented instructional learning, the development of student's creativity becomes one of the most important educational goals, because the ability that can produce the knowledge creatively is required in the digital information knowledge based society. The purpose of this study is to make a basic direction and strategy for the instructional design to develop an on and off line blended instructional design which will help a learning community to be a more collaborative and creative learning community. This research has investigated the concept and the characteristics of collaborative creativity and creative problem solving as the theoretical basis of the design. After that, on the basis of the theories connected with the collaborative creativity theory, the direction and the strategies for the development of collaborative creativity was designed. The design was applied into the real learning community and finally proved the effectiveness of the learning model for the development of the collaborative creativity by the quantitative evaluation.

  • 본 연구는 협력능력에 대한 사전훈련과 협력 스크립트의 상호작용이 협력능력과 공유정신모형 형성에 미치는 영향을 알아보았다. K대 '교육방법 및 교육공학'을 수강하는 96명에게 사전훈련과 서로 다른 협력스크립트를 제공하고, 각 집단 별로 협력학습과정에서 이루어지는 메시지와 협력학습 후 개념도를 분석하였다. 연구 결과, 첫째 사전훈련과 협력 스크립트의 상호작용에 따른 협력 능력에는 유의미한 차이가 없었으나, 협력 스크립트 유형은 협력능력에 유의미한 영향을 미치는 것으로 나타났다. 둘째, 협력에 대한 사전 훈련과 협력 스크립트의 상호작용에 따른 공유정신모형 형성에는 유의미한 차이가 없었으나, 협력 스크립트 유형은 공유정신모형에 유의미한 영향을 미치는 것으로 나타났다. 이 연구는 CSCL 환경에서 효과적인 협력학습활동을 위한 전략 제시라는 점에서 의의가 있다.
