The collaboration hub has been developed since 2004 as an online collaboration space, which supports the various collaborative works amongst small and medium enterprises using information sharing, collaboration project management, and project history management. Because of the change of manufacturing environment and rapid development of information technologies, it should be evolved from the existing version called Collaboration Hub 1.0. Recently, a lot of manufacturing enterprises know the importance of business process management(BPM) and start to introduce BPM systems. Our research group has developed the new version of Collaboration Hub 1.0 called Collaboration Hub 2.0 which contains the BPM concept, the consistent product data management, and the specialized functions overcoming the various variation of manufacturing. This study scrutinizes the meaning and role of the Collaboration Hub 2.0 and introduces an application study of it to the value chain of automobile module development consisted of a leading company and subcontractors. The case study covers the definition, execution and monitoring of collaboration process, the specialized functions overcoming the manufacturing variation and the key performance index of collaboration business.

Recently, the collaboration among small and medium-sized enterprises(SMEs) has been recognized as an effective competitive tool. As several systems have been developed to boost the collaboration, it is necessary to analyze the effectiveness of the systems in terms of their contribution to enhance operational performance of SMEs through objective and quantitative validation. In particular, the analysis for SMEs rather than large-scaled enterprises has not received much attention due to lack of relevant information and difficulty of collecting data. This paper presents a framework for analyzing the effectiveness of the collaboration support system, called i-manufacturing hub, which has been implemented by Korean government. Identification of influential factors to the effectiveness of collaboration hub, and constructing necessary hypotheses are proposed. To overcome the difficulty in data collection only by means of surveys through subjective questionnaires, we exploit system log data that are generated while SMEs use the system. As an initial phase to analyze the effectiveness through hypothesis validation, we discuss several interesting observations and challenges in the direction of enhancing collaboration among SMEs for better operational performance improvement and more participation in the collaboration hub.

Artificial Intelligence (AI) technology has recently grown explosively and is being used in a variety of application fields. Accordingly, the number of AI models is rapidly increasing. AI models are adapted and developed to fit a variety of data types, tasks, and environments, and the variety and volume of models continues to grow. The need to share models and collaborate within the AI community is becoming increasingly important. Collaboration is essential for AI models to be shared and improved publicly and used in a variety of applications. Therefore, with the advancement of AI, the introduction of Model Hub has become more important, improving the sharing, reuse, and collaboration of AI models and increasing the utilization of AI technology. In this paper, we collect data on the model hub and analyze the characteristics of the model hub and the AI models provided. The results of this research can be of great help in developing various multimodal AI models in the future, utilizing AI models in various fields, and building services by fusing various AI models.

발전된 정보통신기술은 개방형협업을 위한 오픈 플랫폼 역할을 수행함으로써 개인간 상호협력을 용이하게 한다. 본 연구에서는 사회연결망이론을 바탕으로 개방형협업의 대표적 형태로 주목받고 있는 오픈소스 프로젝트의 상호협력 네트워크를 살펴보고자 한다. 특히 상호협력 네트워크 내에서의 개방형협업 기여도가 높은 참여자의 네트워크 중심구조를 분석해보고자 한다. 이를 위해 대표적인 오픈소스 프로젝트 플랫폼인 깃허브(GitHub)의 782개 리파지토리의 8,101명의 개발자를 대상으로 782개의 협업 네트워크를 도출함으로써, 협업에 있어 기여도가 높은 개발자의 연결 근접 매개 중심성 특성을 분석하였다. 분석 결과, 연결 매개 근접 중심성이 높은 개발자의 커밋수가 많아지는 것으로 나타났으며, 이중에서도 매개중심성에 의해 그 관계를 가장 잘 설명할 수 있는 것으로 나타났다. 또한 네트워크 사이즈가 클수록, 허브가 존재할수록 개발자의 매개중심성과 커밋수 간의 관련성이 더욱 커지는 것으로 나타났다. 본 연구는 향후 개방형협업의 성공적인 운영을 위한 시사점을 제시해줄 것으로 기대된다.

본 연구는 한국 대학들의 산학협력 역량의 공간적 패턴을 분석하고, 산학협력 연계성이 높은 공간 범위를 파악하기 위한 군집분석을 수행하였다. 대학 설립유형별로는 거점국립대학의 산학협력 역량이 전반적으로 우세하며, 특히 기술이전·사업화 부문과 인프라 부문에서 사립대학이나 일반 국립대학보다 우위에 있는 것으로 나타났다. 산학협력 역량의 공간적 패턴은 시·도별 차이가 비교적 명확히 나타났다. 부문별 산학협력 역량에서, 인재양성 부문과 인프라 부문에 있어서는 지역 간 격차가 크지 않으나, 기술이전·사업화 부문과 창업 부문에 있어서는 지역 간 격차가 비교적 큰 것으로 확인되었다. 산학협력 패턴의 유사성과 공간적 근접성 측면에서 연계성이 높은 공간 범위를 파악하기 위해서 군집분석을 한 결과 15개 군집으로 나누어졌으며, 산학협력 전 부문이 강하게 나타나는 군집에서 거점국립대학이 속해 있는 것으로 나타났다. 따라서 산학협력의 효과성 제고를 통해 지역혁신성장을 달성하기 위한 정책 방안으로 거점국립대학이 허브(hub) 역할을 하고 인근의 지역대학들이 스포크(spoke) 역할을 하는 허브 & 스포크(hub & spoke) 네트워크형 협업 체계의 구축을 제안한다.

For historical and political reasons, South Korea (hereafter Korea), Japan and China have not achieved much progress in regional energy cooperation for decades. However, the rising importance of Northeast Asia (NEA) in the world energy sphere, especially in the global oil market, is providing an opportunity to create an integrated oil market in the region. This study suggests the Northeast Asian Energy Corridor (NEAEC) Initiative as an effective conduit for raising the possibility of the Northeast Asian oil hub project. The NEAEC Initiative combines the model of Europe's Amsterdam-Rotterdam-Antwerp (ARA) with Singapore's AsiaClear as a form of financial collaboration. The study suggests that an electronically integrated Over-the-Counter (OTC) market clearing mechanism accompanied by other key financial instruments among Korea, Japan and China can be an effective means for promoting financial collaboration in the region.

One challenge with teaching practical programming classes is the standardization of development tools on student computers. This is particularly true when a complicated setup process is required before beginning to code, or in remote classes, such as those necessitated by the COVID-19 pandemic, where the instructor cannot provide individual troubleshooting assistance. In such cases, students who encounter problems during the setup process may give up on the class altogether before even beginning to code. Therefore, this paper recommends using GitHub Codespaces as a tool for implementing standardized student development environments from day one. Codespaces provides Docker containers that an instructor can configure in such a way as to enable students to practice installing various coding tools within a controlled space, while also providing a language-specific, fully optimized development environment. In addition, Codespaces may be used more effectively in collaboration with GitHub Classroom, which helps instructors manage both the starter code and coding environment in which students work. In this paper, we compare two semesters of university Node.JS programming classes that utilized different development environments: one localized on student computers, the other containerized in Codespaces online. Then, we discuss how GitHub Codespaces and GitHub Classroom can be used to increase the effectiveness of practical programming classes while also increasing student engagement and programming confidence in class.
