Purpose: This study was to evaluate the applicability of an emergent care management simulation practicum which is for enhancing nursing students' emergent care management competency based on the Nursing Education Simulation Model. Methods: One group pre-post experimental design was conducted for evaluation of the applicability of the simulation practicum. A convenient sample of 60 senior nursing students was participated. The simulation practicum was provided for 26 hours per student at the end of the first semester of senior year. Educational practices in simulation scale, simulation design scale and learning outcomes were measured. Higher positive correlations between variables represent applicability. Descriptive analysis, paired t-test and Pearson correlation coefficient were used for data analyses. Results: Among contractual components of nursing education simulation model, educational practices in simulation and simulation design (r=.80, p<.010), learning outcomes (r=.71-.28, p<.050), simulation design and learning outcomes (r=.72-.30, p<.050) were significantly correlated. Critical thinking (t=-3.63, p<.050) and problem solving competence (t=-2.55, p<.050) were significantly increased by this simulation practicum. It represents the applicability of an emergent care management simulation practicum. Conclusion: This emergent care management simulation practicum was appropriate to enhance the nursing students' emergent care management coping competency.

Purpose: This study was conducted to test the impact of simulation-based education program for emergency airway management on self-efficacy and clinical performance ability. Methods: A quasi-experimental non-equivalent control group pre-post test design was used. A total of 60 nurses, 30 nurses assigned to the simulation-based education group and 30 nurses to a traditional lecture group. The treatment group received a lecture, small group workshop and team simulation whereas the comparison group received lectures. Results: The participants in the simulation-based education group reported significantly higher self-efficacy of emergency airway management compared to participants in the lecture only group (t=5.985, p<.001). The simulation-based education group showed significantly higher clinical performance ability of emergency airway management compared with the lecture group (t=5.532, p<.001). Conclusion: Simulation-based education was verified to be an effective teaching method to improve the self-efficacy, clinical performance skills of nurses in the learning of emergency airway management.

The complex and dynamic job nature and the ever-changing working environment of construction projects inevitably present uncertainties to construction operations. Identification, evaluation and control of uncertainties constitute main elements of risk management and critical tasks of project management in construction. This paper is focused on application of a simplified discrete-event simulation approach in management of schedule-overrun risks, each being the combination of the occurrence probability of an uncertain interruptive factor and its potential consequence in terms of time delay. A case study observed from a concreting operation in Hong Kong is converted into a simulation model and analyzed with an in-house-developed simulation package for demonstrating how the proposed approach can be implemented to manage multiple schedule-overrun risks on construction projects.

A simulation model is proposed to evaluate the effect of correlations between activity durations on the overall project duration. The proposed model incorporates NORTA, a recent developed statistical method, into the simulation process to allow arbitrarily specified marginal distributions for activity durations and any desired correlation structure. The generality is of practical value when systematic data is not available and planners have to rely on arbitrary experts' estimation, which may involve a mixed situation when some activity durations are continuously distributed whereas others are discrete outcomes. The proposed model is validated by showing that the correlation coefficients of the simulation results are close to the originally specified ones. The simulation results are compared to two conventional approaches: PERT and simulation without correlation. The comparisons illustrate that the proposed model can provide important management information, which would otherwise be distorted due to the neglect of the correlations between activity durations.

Purpose: The purpose of this study is to design an experimental simulation model for evaluating the UGV(Unmanned Ground Vehicle) effectiveness in a small unit combat scenario. Methods: We design and build a simulation model to evaluate the combat effectiveness of UGV in a small unit combat scenario. In order to build a simulation model, we used AnyLogic software tool which has functional advantages to describe agent-based simulation model. As for the combat scenario, we applied the typical engagement of mechanized unit equal or lower than battalion level. Analysis process follows the three phases. 1) Design an agent based conceptual medel in a small unit combat scenario. 2) Build a simulation medel using AnyLogic tool. 3) Analyze the simulation results and evaluate the UGV effectiveness. Results: The UGV effectiveness was measured and presented as a numeric values. Those numeric values were represented as a MOE(Measure of Effectiveness) which was the blue survival ratio. Conclusion: We developed an agent based simulation model which can provide a pattern of change how UGV effectiveness varied depending upon the number of UGV in a small unit combat scenario. We also found that the UGV effectiveness grows in the given scenario as the number of UGV increases.

Recently, requests for accurate process planning using simulation have been increasing in many engineering fields including the shipbuilding industry, and many application systems for simulation have been developed. It is difficult, however, for a user to reuse the developed systems, because simulation models in the system are defined by its own method. In addition, the simulation model should be modified whenever a simulation sequence, which is called simulation scenario, is changed. Therefore, in this study, an elementary simulation object is proposed to modularize a simulation model. And the management scheme of simulation scenario is proposed to manage the scenario outside of the simulation models. Also, a simulation template is proposed to increase the development efficiency. To verify the efficiency of the proposed methods, application examples for shipbuilding process planning are implemented.

In this paper, effects of information sharing in multi-level supply chain management have been studied through simulation. The simulation model consists of a manufacturing company as a center, three suppliers, two logistic centers, and three different retail supply lines of each logistics centers. The mathematical model and the simulation were developed when real-time information sharing occurs and does not occur in supply chain under the assumption that each company applies (s, S) inventory policies. In addition, this paper analyzed the effects of the change of variables related to total costs, which compose of total ordering cost, total transportation cost, total carrying cost and shortage cost that are caused by the change of demand of three different patterns with the way of information sharing.

The use of the Web-based Simulation Environment (WBSE) provides a strong influence on supply chain simulations. A virtual supply chain simulation is available to evaluate strategies for reducing response time to customers and for shrinking the finished goods inventory along its supply chain. This paper presents the basic concepts and definitions of Web-Based Global Supply Chain Management (WBGSCM) simulation system. It also discusses the advantages of supply chain simulation modules integration. A Time Synchronization Mechanism (TSM) called Phased Bucket Scheme (PBS) is introduced as an approach of the distributed simulation modules integration.
