Rapid development of information and communication technologies leads firms to take 'smart work' into serious consideration as a new way of working in coming knowledge and information society. However, some jobs may be fit for smart work while some may be not. A $2{\times}2$ framework for smart work readiness assessment is developed in this study through the review of extant literature and a series of focus group activities. Two critical dimensions of smart work are derived and presented as a result: smartness (knowledge versus data) and mobility (mobile versus static). Knowledge intensive jobs with possible mobility seem to be the target group that can be easily converted to smart work while mobile workers with interactive data processing devices seem to be already doing smart work. As mobility is a critical presumption for work to be flexible in terms of time and place, jobs with no mobility are assessed here as not ready for smart work at least at present. This framework is experimentally applied against the published job statistics 2011 in Korea, and used to estimate the number of workers ready for smart work. As a conclusion, discussions on policy implications and further research issues are made at the end.

As the spread of COVID19 has compelled activities in various fields to transform to adapt to the non-face-to-face environment, various activities have either already been transitioned into non-face-to-face methods or been searching for alternative methods to carry out activities in a non-face-to-face manner. However, there are apparent limits in handling this transition with the pre-existing digital technology. Ironically, said limitations are more apparent in the UX design field that has thus far emphasized resolutions based on digital technology. The reason for this stems from the nature of UX design which strongly emphasizes the importance of collaboration. Especially, in the field of UX design, problems are expected to surface under areas of communication and collaboration in workshops, which are productive means of collecting the ideas of interested parties and coming up with other new ideas. Based on the aforementioned rise of necessity, this study aims to assess the characteristics of workshops in the field of UX design and suggest an effective method of transitioning UX workshops into a non-face-to-face environment. Along the line of this process, this study has created a standard process in regards to design workshops with active creation, suggestion, and acceptance of ideas, among the various types of workshops defined by the Nielsen Norman Group. This study also developed a framework consisting of non-face-to-face workshops by combining with the standard process the methodologies of workshop activation and non-face-to-face services meant for communication and designing activities, and confirmed the adaptability and the effectiveness of said transition against various types of workshops. Application of the results of this study is expected to effectively lead the transition into the non-face-to-face environment and improve the collaborative efforts of the interested parties via workshops.

현재의 워크플로우 관리 시스템에서 프로세스를 이루는 각 액티비티의 작업은 단일의 수행자에 의해서 처리되어 진다. 하지만 실제 기업의 프로세스나 과학 분야의 프로세스에서는 단일의 수행자가 아닌 여러 사람들의 협동을 통해 해결해야 하는 작업이나 실시간으로 데이터를 주고받으며 업무를 처리해야 하는 경우가 많다. 이런 작업들을 필요로 하는 곳에 워크플로우 관리 시스템을 도입하기 위해서는 실시간 협동 액티비티의 지원이 필요하다. 하지만 현재의 워크플로우의 표준 스펙에 협동 액티비티의 개념이 확실하지 않고 이에 대한 내용이 정의되어 있지 않기 때문에 실시간 협동 액티비티의 처리가 불분명한 실정이다. 본 연구에서는 표준의 스펙을 확장하여 실시간 협동 액티비티를 지원하도록 기존의 워크플로우 관리 시스템을 확장 설계한다. 워크플로우 관리 시스템을 세부적으로 나누어 워크플로우 모델관점, 워크플로우 엔진 관점, 런타임 클라이언트의 관점으로 크게 세 부분으로 나누고 각 부분에서 실시간 협동 액티비티를 지원하기 위한 요구사항들과 그것의 처리 방안에 대해 제안한다.

BPMN(Business Process Modeling Notation)은 BPMI(Business Process Management Initiative)에서 발표한 것으로서 비즈니스 프로세스 모델링을 위한 표준 표기법이다. BPMN은 표준 모델링 표기법 이므로 다른 모델링 표기법을 익히는데 사용되는 시간을 줄이며 IT 및 비즈니스 사용자들 간의 의사소통을 증진시킬 수 있다. 이에 대응하여 WfMC(The Workflow Management Coalition)는 XPDL 매핑작업을 시도하여 BPMN을 XPDL로 표현할 수 있도록 하였고, 그 결과 BPMN에 매핑시킨 XPDL2.0을 발표하였다. 본 논문에서 설계한 모델링 시스템은 표준 표기법인 BPMN을 통하여 모델링을 하고 그 결과를 국제 표준화 워크풀로우 정의 언어인 XPDL2.0으로 제공하는 워크플로우 모델링시스템을 제안하여 다른 워크플로우 시스템들과의 상호 호환성을 제공하는 것이며, 역할 기반의 모델링 방식으로 복잡한 모델링 작업을 단순화 시킬 수 있다. 즉, 워크플로우 모델링 기능에 실시간 그룹웨어 특성들을 통합하여, 한 차원 높은 수준의 모델링 환경제공을 통하여 기존의 워크플로우 시스템들이 지원하지 못 했던 워크플로우 모델링 협동 작업을 실시간으로 지원 할 수 있을 문만 아니라, 요즘과 같이 대형화와 복잡화 그리고 다양화의 특징을 갖는 조직들의 워크플로우 들에 대한 효율적인 분석 및 모델링 환경을 제공하기 위한 워크플로우 모델링 시스템을 제안한다.

A study on workflow as an automated business processing system is done recently. This appear proposes a method to verify commitability and integrity of workflow specifications, which include various dependencies between parallel tasks, using petri nets. For this, firstly, e describe briefly workflow specification method using workflow graphs. Secondly, we propose a method to convert a workflow graph into a petri net to verify workflow specifications. Thirdly, we suggest the commitability verification method using petri nets to check whether workflow specifications can commit or not and the integrity verification method to check whether invalid components exist or not. Lastly, we implement the proposed verification method and propose a defect extraction method.

The Grid is new infrastructure to provide computing environment for grand challenge research by sharing large-scale resources. Currently the Globus becomes a de facto standard middleware to construct Grid and supports core services such as resource management, security, data transfer, information services, and so on. However, it still needs more works and researches to satisfy requirements from various grid applications. A workflow management is becoming a main service as one of the important grid services for complex grid applications. We propose a Meta Scheduling Framework (MSF) in this paper. The MSF provides a XML-based Job Control Markup Language (JCML) for describing information and procedures of grid applications, and a workflow management service for scheduling the job using the JCML and for processing the job effectively.

The major problems in workflow system which controls business process arise with the difficulty of managing a vast volume of data. In this paper, a more reasonable method to manage workflow data is proposed after analyzing the data being used in workflow system. The data used in workflow system can be classified to model data, control data, workitem data and relevant data. The prime accent is placed on the workflow model data, as the model data is normally consistent and referenced more frequently that if the data is used efficiently, it is anticipated to give a good performance to workflow system. Relying on an intensive study, this paper designs and develops a model data system. This model data system is based on memory and manages versions, consistency, dynamic modification, and etc

Recently it is proposed that the Bayesian networks used as conversational agent for topic inference is useful but the Bayesian networks require much time to model, and the Bayesian networks also have to be modified when the scripts, the database for conversation, are added or modified and this hinders the scalability of the agent. This paper presents a method to improve the scalability of the agent by constructing the Bayesian network from scripts automatically. The proposed method is to model the structure of Bayesian networks hierarchically and to utilize Noisy-OR gate to form the conditional probability distribution table (CPT). Experimental results with ten subjects confirm the usefulness of the proposed method.

CoSlide 협업 시스템은 웹데브 기반의 CoSlide 서버와 윈도우즈 응용프로그램인 CoSpace 클라이언트로 구성된다. CoSlide 서버는 Jakarta Slide 서버의 확장으로 협업시스템 구성원간의 자원 공유를 위한 다양한 종류의 작업장을 지원하며, CoSpace 클라이언트는 CoSlide 서버의 다양한 기술 지원을 사용자 중심의 인터페이스로 제공한다. 협업을 동적으로 지원하기 위해서는 워크플로우 시스템이 필요하다. 워크플로우 시스템은 협업시스템에 등록된 사용자가 워크플로우가 정의된 작업장에 자원을 등록하였을 때 정의된 워크플로우에 따라서 자원의 이동, 복사 그리고 메시지전송 등의 과정을 자동적으로 수행한다. 워크플로우 정의는 XML 파일 형식으로 워크플로우 작업장에 생성되어 존재하며 반응적 워크플로우가 발생하였을 때 XML 파일의 정의에 따라 자동적으로 이뤄진다. 협업 시스템에 워크플로우 시스템을 적용시키면 협업 시스템에 등록된 자원을 수동으로 분류하거나 협업에 필요한 다른 그룹의 특정 사용자에게 수동으로 전송해야 하는 불편함을 없앨 수 있다.

The advance in mobile devices such as smartphone, wireless networking, and Internet technologies enables many organizations to improve drastically not only the ways of carrying out every job activity but also their business processes and operations management. As the effort to work smart utilizing the technological change, they are interested in the implementation of Smart Work environment. In this paper we examine several types of smart work and their service scenarios. We also describe the structures of networking and system configurations for building up the smart work environment. These study results may be useful as reference materials for the successful implementation of smart work.
