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.

본 논문에서는 모바일 디바이스들 간에 협업을 제공할 수 있는 프레임워크를 제시하고, 그를 기반으로 헬스케어 응용 서비스를 구현하였다. 제안한 프레임워크는 3가지의 구성요소인 센서와 모바일 디바이스 그룹, 홈 서버의 상호작용을 위한 인터페이스를 정의하고, 고정형과 이동형 디바이스들(PDAs)을 이용한 협업 환경을 제시한다 이동형 디바이스들 간의 정보의 교환은 Push와 Pull 방식을 사용하였으며, 다수의 센서로부터 수집된 정보는 모바일 디바이스들과 홈 서버에 의해 공유 또는 교환한다. 우리의 협업 프레임워크는 이전 연구에서 개발된 분산객체그룹프레임워크(DOGF)에서 구현된 객체그룹관리, 정보저장, 접근제어에 따른 허가와 승인기능들을 응용 인터페이스를 통해 제공받게 된다. 헬스케어 서비스의 중요한 부분인 보안을 지원하기 위해 보안정보를 구분하였고, 정보의 이용 권한을 DOGF의 보안 객체를 통하여 인증할 수 있는 절차를 제시하였다. 또한, 사용자의 프로필 정보를 제공함으로써 사용자에 따른 서비스 객체에 대한 권한 검사를 하였다. 각 모바일 디바이스와 홈 서버에 구현된 컴포넌트는 TMO 스킴을 적용하였으며, 이들 분산된 컴포넌트들 간의 통신을 지원하기 위해 분산 실시간 미들웨어인 TMOSM을 사용하였다. 끝으로 협업 프레임워크 상에서 제시한 헬스케어 응용 시나리오의 수행성을 GUI를 통해 보였다.

Purpose As non-face-to-face work environments become common due to COVID-19, interest in online collaboration tools that can communicate smoothly without time and space limitations is continuously increasing. Most of the prior studies are about the introduction, use intention, and satisfaction of cloud computing-based collaboration tools, and studies on the effects of collaboration tools on work-life balance and quality of life are somewhat lacking. Therefore, in this study, the characteristics of cloud computing-based collaboration tools were derived, and the effect on job satisfaction during work and job stress outside of working hours was confirmed. Design/methodology/approach This study applied the S-O-R framework and conducted an online survey of office workers who used cloud computing-based collaboration tools for more than three months. Hypotheses were tested using structural equations. Findings As a result of the analysis, among the characteristics of collaboration tools, stability, usefulness, and interoperability had higher job satisfaction as more stimuli were applied. In addition, the higher the job satisfaction during work, the higher the job performance, work-life balance, and quality of life.

This paper proposes the distributed virtual environment framework for collaboration between heterogeneous platforms. The proposed system consists of Client, Content Server(CS), and Reflector Server(RS). The Client is composed of VR library(VRL), Interaction Manager(IM), Distributed Interaction Manager(DIM), and Network Interface(NI). The proposed Client structure can support various display environments. The XML-based IM and DIM lets the users define and add the interactions. The proposed Server structure synchronizes the distributed interaction between heterogeneous platforms and provides transparency to the users. Therefore, the proposed framework enables the users to implement virtual collaboration environment for their tasks. Moreover, it can also be used for research and development activities between a large number of the remote users. The usefulness of the framework was verified by applying it to the virtual heritage tour system.

본 논문에서는 원격지간에 수행되는 모델링을 지원하는 UML CASE를 제시하고자 한다. 공동작업 지원을 위해 필요한 기능을 설정하였으며, 기능에 기반하여 확장과 재사용성 증대를 위해 프레임워크 개념을 적용하고 이를 계층화시켰다. 또한 프레임워크를 기반으로 실제 UML CASE 도구를 구축하였다. 본 논문에서 제시하는 공동작업을 지원하는 UML CASE 도구는 여러 이해관계자의 의견을 실시간으로 반영하게 해줄 뿐만 아니라, 통합되고 일관성있는 모델링에 기여할 것으로 기대된다.

This paper explores, explains and describes a framework for analyzing collaborative governance, decent work and innovation as fundamental elements of sustainable workplaces through case study of Philippine science and technology (S & T) parks. Rules, or the legal infrastructure, are particularly significant considerations that facilitate or hinder collaboration. Industrial relations/human resource (IR/HR) practices are essential to collaboration and decent work. Employee consultation and labor-management council or committee are examples of IR/HR practices that might contribute to collaboration and decent work in firms and workplaces in S & T parks as they are team approaches to production, too. Collaboration and decent work enhance the capacity to innovate. In the long run, collaborative governance, decent work and innovation tend to converge in the concept of sustainable development. The interdependencies and interactions among collaborative governance, decent work and capacity to innovate in firms operating in S & T parks make possible new solutions to new problems (i.e., innovation) and, thus, sustainable workplaces.

The increasing dynamic and distributed nature of a business and manufacturing environment makes it hard to collaborate between design and manufacturing parties. The seamless collaboration necessitates a manufacturing quote service (MQS) that delivers manufacturing quotes timely for designer's requests. After envisioning a SOA-inherited collaboration framework, the paper details MQS' functionalities, and syntax and semantics of collaboration messages (i.e., RFQ and manufacturing quote). The MQS is implemented as a Web Service so as to be accessible by designers. For each RFQ, the MQS adaptively generates a responding manufacturing quote by using the DPM library and real-time shop status information. The paper also presents an evolution process that shows the whole process of RQF generation from given product design data. The proposed framework enabled partners to exchange engineering data rapidly and adaptively during the dynamic collaboration, and also increased the benefits of distributed and global production.
