As the collaboration of WFMS(workflow management systems) in enterprises increases, security protocols could be considered a critical factor affecting secure operation of WMFS. The security protocol of WFMS could not reflect the nature of collaboration in WFMS, resulting to collaboration of WFMS on Internet causing the operation problems of WFMS. This study suggests collaboration based security protocols based on the collaboration of WFMS on Internet. To reflect the nature of collaboration in WFMS, this study analyzes security requirements for WFMS. Based on security requirements, this study suggests a security architecture and security protocols for WFMS using security agents.

In e-commerce systems that deal with a large number of items, the function of personalized recommendation is essential. Collaborative filtering that is a successful recommendation algorithm, suffers from the sparsity, cold-start, and scalability restrictions. Additionally, this work raises a new flaw of the algorithm, inconsistent performance of recommendation. This is also not measurable by the current MAE-based evaluation that does not consider the deviation of prediction error, and furthermore is performed independently of precision and recall measurement. To evaluate the collaborative filtering comprehensively, this work proposes an extended evaluation model that includes the current criteria such as MAE, Precision, Recall, deviation, and applies it to cluster-based combined collaborative filtering.

This study examined the factors that influence creative performance in corporate collaboration projects. Specifically to facilitate team collaboration, we identified that scaffolding, which is one of the important factors in organizational learning communication, and the Boundary Objects, which are collaboration tools & vehicle, influence performance. The survey was collected for 203 employees who experienced collaborative projects, and three-step mediated regression analysis was conducted after conducting exploratory factor analysis. In other words, we examined the median effect of boundary objects on the impact of scaffolding on creative collaborative performance. Analysis showed that while the effects of the boundary objects in relation to the impact of cognitive scaffolding on creative performance were not significant, emotional scaffolding had a full-scale effect on the creative performance and also had a full-scale effect on the efficacy performance. Given these results, it is necessary to share a vision and form personal relationships among team members in order to activate them, since scaffolding is useful in organizational learning and boundary objects also have some effect as a medium for promoting collaboration in projects.

This study identified the perceptions of science and technology researchers about interdisciplinary collaboration and the difficulties experienced in the collaboration process and the types of strategies they set up to overcome them. For this study, a questionnaire was developed with five-point Likert-scale questions that confirm attitudes toward interdisciplinary collaboration and qualitative questions that describe difficulties and strategies to overcome difficulties experienced in the collaboration experience. A total of 79 domestic science and technology researchers responded to the survey, and the collected data were analyzed quantitatively and qualitatively. As a result of the study, it was confirmed that the recognition of the efficacy of collaboration had an important influence on the intention of collaboration, but the level of the recognition of the efficacy of collaboration was relatively low. In addition, there were four types of difficulties in the interdisciplinary collaboration process, and seven types of strategies were identified to overcome these. Based on these findings, it was suggested that convergence education should reflect the pluralistic nature of modern science and the features of various collaborations that occur within it.

Collaborative processes among team members including communication, coordination, and information-handling processes either during pre-construction or project execution are required in order to accomplish the objectives of construction projects. However, current construction management practice does not explicitly take the effect of organizational aspects on project performance into account. This paper introduces a method to understand collaborative processes in an explicit and systematic fashion. An agent-based simulation of collaborative working processes within construction project teams was designed from game theory perspective and implemented. The simulation produced both individual behavior and network dynamics. Individuals represented as agents made efforts to improve performance by communication and coordinating with other members, and overall team network was emerged as a result of interactions among members. Interestingly, it was found that the tendency of forming cohesive subgroups increased when sustaining relations with between-group partners incurs higher cost. The primary contribution of this paper is that it presented an explicit approach to examining collaborative working processes in construction project teams and it extended existing computational organization and network studies by integrating individual behavior models and network models.

This study aims to empirically analyze the structural effects of partnership characteristics between buyers and suppliers on the performance in supply chains. To this end, an in-depth literature review was performed in advance and four partnership characteristics involving information sharing, participativeness, interdependence, solidarity were identified, and a research model was validated by incorporating collaboration, trust, satisfaction. To analyze data collected from 124 companies, structural equation modeling was employed to test hypotheses proposed in this study and the findings are shown as follow. First, the partnership between buyers and suppliers was confirmed to have a positive effect on collaboration, trust and satisfaction. Second, both of trust and satisfaction were found to positively influence collaboration. Third, our findings also validated that collaboration and trust between buyers and suppliers had significant influences on supply chain performance, however, we found no evidence of a statistically significant relationship between satisfaction and performance. Based on these findings, discussions on the implications of this study and suggestions for further research were given finally.

This paper presents and analyzes a novel technique that makes it possible to improve the performance of low-end embedded systems through SoC(System-on-a-Chip) platform supporting dynamic cooperation between hardware and software modules. Traditional embedded systems with limited hardware resources have the poor capability of carrying out multi-tasking jobs including complex calculations. The proposed SoC platform, which provides dynamic cooperation between hardware and software modules, decomposes a single specific system into tasks for given system requirements. Additionally, we also propose a technique for efficient communication and synchronization between hardware and software tasks in cooperation with each other. Several experiments are conducted to illustrate the application and efficiency of the proposed SoC platform. They show that the proposed SoC platform outperforms the traditional embedded system, where only software tasks run, as the number of memory access is increased and the system become more complex.

Applying maintenance simulation using virtual mockup in product design phase enables maintainability test before prototyping physical products, and it is expected to reduce product development costs. The simulation results can be reused as contents of service manuals and RAM (Reliability, Availability, Maintainability) analysis data. Maintenance simulation should provide realistic representation of physical property of virtual product, assembly relation between parts and manipulation process to verify feasibility of product design. The simulation system should be extended to collaborative virtual environment to perform collaborative maintenance procedures. In this paper, the three layered system architecture and the physics based collaborative interaction technique are proposed to extend current maintenance simulation into collaborative virtual environment. The proposed system was implemented as ViMMS (Virtual Mockup Maintenance Simulation system), and compared with case study results of VADE (Virtual Assembly Design Environment). As a result, the ViMMS encompassed broader range of maintenance tasks by using physics based collaborative interaction technique.

It is important to control performance and a Sustainable Collaboration (SC) for the successful Supply Chain Management (SCM). This research developed a control model which analyzed SCM performances based on a Balanced Scorecard (ESC) and an SC using Support Vector Machine (SVM). 108 specialists of an SCM completed the questionnaires. We analyzed experimental data set using SVM. This research compared the forecasting accuracy of an SCMSC through four types of SVM kernels: (1) linear, (2) polynomial (3) Radial Basis Function (REF), and (4) sigmoid kernel (linear > RBF > Sigmoid > Polynomial). Then, this study compares the prediction performance of SVM linear kernel with Artificial Neural Network. (ANN). The research findings show that using SVM linear kernel to forecast an SCMSC is the most outstanding. Thus SVM linear kernel provides a promising alternative to an SC control level. A company which pursues an SCM can use the information of an SC in the SVM model.
