A stochastic modeling approach as a mathematical method for workflow intelligence is widely used for analyzing and simulating workflow models in the literature. In particular, as a resource-centric modeling approach, this paper proposes a stochastic model to represent work-handover relationships between performers in a workflow-supported social network. Calculating probabilities for the work-handover relationships are determined by two types of probabilities. One is the work-transition probability between activities, and the other is the task assignment probability between activities and performers. In this paper, we describe formal definitions of stochastic workflow models and stochastic work-handover relationship models, as well. Then, we propose an algorithm for extracting a stochastic work-handover relationship model from a stochastic workflow model. As a consequence, the proposed model ought to be useful in performing resource-centric workflow simulations and model-log comparison analyses.

In this paper, we propose a novel analysis method and its algorithms to perform the betweenness centrality measurements on a valued and directed workflow-supported social network. The conventional workflow-supported social network model is to represent the existences of task transferring relationships among their performers by using a binary social network. However, it is necessary to consider not only the existences of task transferring relationships but also their quantities and directions in order to obtain much more effective and sophisticated analysis results. In conclusion, this paper newly defines a concept of valued and directed workflow-supported social network, and its betweenness centrality analysis method and algorithms. Especially, to verify the proposed method and algorithms, we try to apply the conventional method and the proposed method to an example workflow model respectively, and compare their betweenness centrality analysis results.

The purpose of this study was to investigate the current status and problems of the social service delivery system for women in Korea, and to suggest ways to improve its function. The current social service delivery system in the public sector contains a network of services connected with the Division of Women's Welfare in the Ministry of Health and Social Welfare. This study focused on evaluating the function of the public service delivery system from the perspective of the service providers. A survey of 167 civil officers in charge of women's welfare services in the city.county.district administrations, and 202 women's welfare counselors around the country was conducted in order to evaluate their current duties, effectiveness of services, and problems of the current system Six criteria including integration, continuity, accessibility, adequacy, efforts and professionalism were used for evaluating the effectiveness of the social service delivery system for women. According to the survey, the civil officers and women's counselors gave relatively favorable ratings for their job effectiveness and job satisfaction. However, their duties involving guidance and counseling of prostitute women and operation of women's welfare councils received least favorable evaluation. Moreover, in terms for job satisfaction, these service providers were less satisfied with their working conditions than their relationships with clients or colleagues. In addition, budget and personnel shortages were the most serious problems facing the delivery system Further analysis showed that professionalism and accessibility of the service delivery system had positive impact on job effectiveness while efforts, integration, accessibility and adequacy had positive impact on job satisfaction of the service providers. These findings have potential implications for designing more effective social service delivery system for women.

The information generated from large and complex construction projects transfer and evolve in long-term business cycle. Therefore, while there is any problem, such as delay, the cause of the problem might relate to the previous business process rather than where it arises. However, for complex project players and business relationships, it is unsuitable to search an information flow using traditional retrieval methods. This research addresses a relationship-based information search system to analyze the information flow in large-scale and complex construction projects. First, we identified the components of the information retrieval system customizing for a large-scale complex construction projects, and then developed the inference algorithm which define the relationship between business processes. For the validation, we applied the system on a business information system of urban regeneration projects and suggested some application using information flow retrieval system for project players and project managers. Using the system, players are easy to prepare for their work process and managers can define the causal flow of the problem.

본 논문은 작업 현장에서 청각장애인의 의사소통을 보조하는 한국 수화 메시지 보드의 개발에 대하여 다룬다. 청각 장애인은 일상적인 직업 현장에서 의사소통이 자유롭지 못하여 업무에 잘 적응하지 못하고 사내의 인간관계에 많은 어려움을 겪고 있다. 문자를 이용한 정보 전달을 통해 모든 의사소통을 대체할 수 있을 것이라는 일반적인 생각과는 달리, 청각장애인의 경우 비장애인과 비교하여 사물의 개념 습득에 어려움이 있을 수 있으며 마찬가지로 사용하는 어휘수도 제한적인 경우가 많아 문자를 통한 의사소통에는 명확한 한계가 존재한다. 실제로 청각 장애 근로자가 이직하는 사유로 의사소통이나 인간관계가 높은 비중을 차지한다. 수화 메시지 보드는 크게 사내 네트워크를 이용한 공지 사항 전달을 위한 용도와 복수 개의 메시지 보드 간 문자 송수신의 용도로 사용 가능하다. 비장애인이 청각장애인에게 문자 입력으로 의사를 전달하면, 전달된 문자는 문자-수화 번역기를 통해 자동으로 수화로 번역되어 아바타의 수화 동작으로 화면에 출력된다. 전체 시스템은 수화 아바타를 포함한 그래픽 유저 인터페이스 (GUI), 수화 데이터베이스 및 한글 형태소/문장 분석기를 포함하는 문자-수화 번역기, 그리고 TCP/IP 기반의 문자 전송기의 세 부분으로 나뉜다. 본 논문에서는 수화 데이터베이스의 단어 선정을 위한 대상 작업 현장을 청각 장애 근로자가 타 직업에 비해 많은 비중을 차지하는 전자 부품 조립 업체로 한정하였다. 수화 데이터베이스는 자음 14종, 모음 17종, 숫자 15종, 일상생활 용어 1000종, 전자 부품 조립 업체에 특화된 단어 50종 및 직업 교육 관련 용어 50종으로 이루어진 총 1146종의 수화 단어를 포함하며, 수화 데이터베이스에 등록되지 않은 단어에 대해서는 지화로 표현하도록 한다. 이 중 전자 부품 조립 업체 특화 단어와 관련하여서는, 현재 동일한 분야의 작업 현장이라 하더라도 각 사업장 간 사용되는 수화가 통일되지 않아 문헌 조사 및 현장 조사를 통해 사용 빈도가 높고 형태가 공통적인 50종을 추려내었다. 본 연구는 실제 업무현장에서 청각장애인이 겪는 의사소통의 문제를 효과적으로 해결함으로써, 청각장애인이 직업 현장에 보다 쉽게 적응하도록 도움을 줄 뿐만 아니라, 일을 통해 자아 실현을 하도록 돕는 방안이 될 수 있다는 점에서 중요한 의의를 갖는다.

본 연구는 내부조직관계에서 대인신뢰를 구성원들의 상대방(부하, 동료, 상사)에 대한 능력, 상호 믿음과 지원에 기반을 두는 것으로 정의하고, 조직구성원들의 협력적 관계는 조직결과의 향상을 가져올 수 있다는 것을 가정하여, 대인간의 신뢰가 조직생산성의 향상에도 영향을 미치는지를 확인하고자 한다. 연구결과에 따르면 직무수행에 관련한 의사결정에 참여도와 성과의 피드백만족도 그리고 개방적 의사 전달에 대한 만족도가 높을수록 업무생산성이 높아진다는 것을 알 수 있었다. 특히 대인신뢰에 기반을 둔 행정조직은 또 다른 관리적 도전인 문화적 다양성의 증대와 고객기대의 충족에 대처하게 되므로, 상사와 부하간의 대인신뢰를 구축하는 것은 구성원의 직무생산성을 증대시키고 조직몰입을 강화시킬 수 있는 원동력이 된다는 것을 알 수 있었다.

In workflow process intelligence and systems, workflow process mining and analysis issues are becoming increasingly important. In order to improve the quality of workflow process intelligence, it is essential for an efficient and effective data center storing workflow enactment event logs to be provisioned in carrying out the workflow process mining and analytics. In this paper, we propose a three-dimensional process-aware datacube for organizing workflow enterprise data centers to efficiently as well as effectively store the workflow process enactment event logs in the XES format. As a validation step, we carry out an experimental process mining to show how much perfectly the process-aware datacubes are suitable for discovering workflow process patterns and its analytical knowledge, like enacted proportions and enacted work transferences, from the workflow process enactment event histories. Finally, we confirmed that it is feasible to discover the fundamental control-flow patterns of workflow processes through the implemented workflow process mining system based on the process-aware data cube.
