    The importance of operator training using operator training simulator has been recognized intensively. Since 1986, we have been developing and providing many PWR simulators in Japan. We also have developed some training support systems connected with the simulator and the integrated training support system to improve training effect and to reduce instructor's workload. This paper describes the concept and the effect of the integrated training support system and of the following sub-systems. We have PES (Performance Enhancement System) that evaluates training performance automatically by analyzing many plant parameters and operation data. It can reduce the deviation of training performance evaluation between instructors. PEL (Parameter and Event data Logging system), that is the subset of PES, has some data-logging functions. And we also have TPES (Team Performance Enhancement System) that is used aiming to improve trainees' ability for communication between operators. Trainee can have conversation with virtual trainees that TPES plays automatically. After that, TPES automatically display some advice to be improved. RVD (Reactor coolant system Visual Display) displays the distributed hydraulic-thermal condition of the reactor coolant system in real-time graphically. It can make trainees understand the inside plant condition in more detail. These sub-systems have been used in a training center and have contributed the improvement of operator training and have gained in popularity. (author)

    An early fault diagnostic system has been developed addressed to timely trouble shooting in process plants during any operational modes. The theory of this diagnostic system is related with the usage of learning methods for automatic generation of knowledge bases. This approach enables the conversion of ''cause→effect'' relations into ''effect→possible-causes'' ones. The diagnostic rules are derived from the operation of a plant simulator according to a specific procedure. Flexibility, accuracy and high speed are the major characteristics of the training simulator, used to generate the diagnostic knowledge base. The simulator structure is very flexible, being based on LEGO code but allowing the use of practically any kind of FORTRAN routines (recently also ACSL macros has been introduced) as plant modules: this permits, when needed, a very accurate description of the malfunctions the diagnostic system should ''known''. The high speed is useful to shorten the ''learning'' phase of the diagnostic system. The feasibility of the overall system has been assessed, using as reference plant the conventional Sampierdarena (Italy) power station, that is a combined cycle plant dedicated to produce both electrical and heat power. The hardware configuration of this prototype system was made up of a network of a Hewlett-Packard workstation and a Digital VAX-Station. The paper illustrates the basic structure of the simulator used for this diagnostic system training purpose, as well as the theoretical background on which the diagnostic system is based. Some evidence of the effectiveness of the concept through the application to Sampierdarena 40 MW cogeneration plant is reported. Finally an outline of an ongoing application to a WWER-1000 plant is given; the operating system is, in this case, UNIX. (author)

    The advancement of high technologies and the arrival of the information age have caused changes to the modern warfare. The military forces of many countries have replaced partially real training drills with training simulation systems to achieve combat readiness. However, considerable types of training simulation systems are used in military settings. In addition, differences in system set up time, functions, the environment, and the competency of system operators, as well as incomplete information have made it difficult to evaluate the performance of training simulation systems. To address the aforementioned problems, this study integrated analytic hierarchy process, soft set theory, and the fuzzy linguistic representation model to evaluate the performance of various training simulation systems. Furthermore, importance-performance analysis was adopted to examine the influence of saving costs and training safety of training simulation systems. The findings of this study are expected to facilitate applying military training simulation systems, avoiding wasting of resources (e.g., low utility and idle time), and providing data for subsequent applications and analysis. To verify the method proposed in this study, the numerical examples of the performance evaluation of training simulation systems were adopted and compared with the numerical results of an AHP and a novel AHP-based ranking technique. The results verified that not only could expert-provided questionnaire information be fully considered to lower the repetition rate of performance ranking, but a two-dimensional graph could also be used to help administrators allocate limited resources, thereby enhancing the investment benefits and training effectiveness of a training simulation system.

    Microsurgical techniques are essential in plastic surgery; however, inconsistent training practices, acquiring these skills can be difficult. To address this, we designed a standardised laboratory-based microsurgical training programme, which allows trainees to develop their dexterity, visuospatial ability, operative flow and judgement as separate components. Thirty trainees completed an initial microsurgical anastomosis on a chicken femoral artery, assessed using the structured assessment of microsurgical skills (SAMS) method. The study group (n = 18) then completed a 3-month training programme, while the control group (n = 19) did not. A final anastomosis was completed by all trainees (n = 30). The study group had a significant improvement in the microsurgical technique, assessed using the SAMS score, when the initial and final scores were compared (Mean: 24 SAMS initial versus 49 SAMS final) (p group had a significantly lower rate of improvement (Mean: 23 SAMS initial versus 25 SAMS final). There was a significant difference between the final SAMS score of the study group and that of senior surgeons (Mean: 49 study final SAMS versus 58 senior SAMS). This validated programme is a safe, cost-effective and flexible method of allowing trainees to develop microsurgical skills in a non-pressurized environment. In addition, the objectified skills allow trainers to assess the trainees' level of proficiency before operating on patients.

    The RELAP/SCDAPSIM code, designed to predict the behaviour of reactor systems during normal and accident conditions, is being developed as part of an international nuclear technology development program called SDTP (SCDAP Development and Training Program). SDTP involves more than 60 organizations in 28 countries. One of the important applications of the code is for simulator training of university faculty and students, reactor analysts, and reactor operations and technical support staff. Examples of RELAP/SCDAPSIM-based system thermal hydraulic and severe accident simulator packages include the SAFSIM simulator developed by NECSA for the SAFARI research reactor in South Africa, university-developed simulators at the University of Mexico and Shanghai Jiao Tong University in China, and commercial VISA and RELSIM packages used for analyst and reactor operations staff training. This paper will briefly describe the different packages/facilities. (authors)

    There's a growing need for fire departments to adopt a safe and fair method of training to ensure that the firefighting commander is in a position to manage a fire incident. Visual simulation training systems, with their ability to replicate and interact with virtual fire scenarios through the use of computer graphics or VR, become an effective and efficient method for fire ground education. This paper describes the system architecture and functions of a visual simulated training system of fire fighting on oil storage, which adopting Delat3D, a open source game and simulation engine, to provide realistic 3D views. It presents that using open source technology provides not only the commercial-level 3D effects but also a great reduction of cost.

    A dispatcher training simulator (DTS) is a real-time Human Machine Interface (HMI)-based control tool that is able to visualize industrial control system processes. The present study was aimed at developing a simulator tool for boilers in a thermal power station. The DTS prototype was designed using technical data of thermal power station boilers in Indonesia. It was then designed and implemented in Wonderware Intouch 10. The resulting simulator came with component drawing, animation, control display, alarm system, real-time trend, historical trend. This application used 26 tagnames and was equipped with a security system. The test showed that the principles of real-time control worked well. It is expected that this research could significantly contribute to the development of thermal power station, particularly in terms of its application as a training simulator for beginning dispatchers.

    Training is a major endeavor in all modern societies. Common training methods include training manuals, formal classes, procedural computer programs, simulations, and on-the-job training. NASA's training approach has focussed primarily on on-the-job training in a simulation environment for both crew and ground based personnel. NASA must explore new approaches to training for the 1990's and beyond. Specific autonomous training systems are described which are based on artificial intelligence technology for use by NASA astronauts, flight controllers, and ground based support personnel that show an alternative to current training systems. In addition to these specific systems, the evolution of a general architecture for autonomous intelligent training systems that integrates many of the features of traditional training programs with artificial intelligence techniques is presented. These Intelligent Computer Aided Training (ICAT) systems would provide much of the same experience that could be gained from the best on-the-job training.

    Obstetrical emergencies require the rapid formation of a team with clear communication, strong leadership, and appropriate decision-making to ensure a positive patient outcome. Obstetric teams can improve their emergency response capability and efficiency through team and simulation training. Postpartum hemorrhage is an ideal model for team and simulation training, as postpartum hemorrhage requires a multidisciplinary team with the capability to produce a protocol-driven, rapid response. This article provides an overview of team and simulation training and focuses on applications within obstetrics, particularly preparation for postpartum hemorrhage.

    Laparoscopic surgery including robotic surgery allows the surgeon to be able to conduct minimally invasive surgery. A surgeon is required to master difficult skills for this surgery to compensate for the narrow field of view, limitation of work space, and the lack of depth sensation. To counteract these drawbacks, we have been developing a training simulation system that can allow surgeons to practice and master surgical procedures. In addition, our system aims to distribute a simulation program, to provide a means of collaboration between remote hospitals, and to be able to provide a means for guidance from an expert surgeon. In this paper, we would like to show the surgery simulation for da Vinci surgery, in particular a cholecystectomy. The integral parts of this system are a soft tissue model which is created by the sphere-filled method enabling real-time deformations based on a patient's data, force feedback devices known as a PHANToM and the Internet connection. By using this system a surgeon can perform surgical maneuvers such as pushing, grasping, and detachment in real-time manipulation. Moreover, using the broadband communication, we can perform the tele-surgical simulation for training.

    Confronted as of its origins with the on-board layout constraints of the French Navy ships, TECHNICATOME integrates, as of the design, the ergonomics and the risks control related to the human factors. During more than 30 years, TECHNICATOME demonstrated a one of a kind know-how from the design to the execution of powerful, flexible and highly available nuclear compact reactors. A total control which includes up to the supervision and monitoring systems, the acoustic discreetly of the systems and its components, implemented on on-board reactors, testing reactors as well as experimental reactors. The functionalities of simulation were right from the start used by TECHNICATOME during the design phase of these installations to carry out operation engineering analyses on the thermal hydraulic and neutron aspects, to validate the principles of operation of the supervision systems like by the use of digital models in 3D CAD to validate the kinematics of operation or the interactions between systems. More recently, and starting from the end of the Nineties, a thought needs was launched to determine the interests related to the development of a training simulator associated with these installations with objectives, among others, to ensure the phase of initial training of the new operators, to widen the field of the training to the accidental situations, the management of crisis and crews behaviour supervision, the possibilities of replay which support the consolidation of the acquired knowledge(debriefing) with situation resume, and to increase the overall training capacity. An upgrade and modernisation project of these various simulation means was thus launched since 2001 with the objective to optimize the whole of the tasks supported by these means. (author)

    Little research has been published about the impact of simulation technology on the learning process of novel motor skills. Especially the role of augmented feedback (FB) on the quality of performance and the transfer of the acquired behaviour to a no-augmented FB condition require further investigation. Therefore, novice dental students were randomly assigned to one of three groups and given the task of drilling a geometrical class 1 cavity. The FB group trained under augmented visual FB conditions, provided by the virtual reality (VR) system (DentSim). The no-FB group practised under normal vision conditions, in the absence of augmented FB. A control group performed the test sessions without participating in any training programme. All preparations were evaluated by the VR grading system according to four traditional (outline shape, floor depth, floor smoothness and wall inclination), and two critical, criteria (pulp exposure and damage to adjacent teeth). Performance analyses revealed an overall trend towards significant improvement with training for the experimental groups. The FB group obtained the highest scores. It scored better for floor depth (P training groups. Consequently, drilling experience on a VR system under the condition of frequently provided FB and lack of any tutorial input was considered to be not beneficial to learning. The present data are discussed in view of the guidance hypothesis of FB, which refers to the apprentice's dependence on FB.

  2. Training by simulation

    Effective training by simulation is a matter of 1. accurate definition of the training need, 2. selecting the right hardware/software package to do the job cost effectively, 3. careful, methodical building of the training program and 4. an appropriate setting, such as a well-equipped training center. Several points seem clear: 1. ''Computer shock'' or computer phobia -- that is, fear of the simulator, can be a factor with some of the older operators. But it quickly disappears once they're into the program, and learn the versatility and the exciting dynamics of simulators. 2. Operator training is becoming more sophisticated throughout the HPI. Among other things, operators should get out into the plant to learn more about how their actions in the control room impact the plant. Operators are becoming more ''big picture'' oriented. 3. When inexperienced training instructors are used, they should attend a good ''train the trainer'' course emphasizing platform skills and instructional technology. 4. Operators need as much ''hands on'' experience with the plant's actual operating equipment as possible. The cognitive ''linkage'' between that equipment and what they see on the CRT is vitally important.

  3. Analysis of simulator training

    1983-01-01

    A method has been developed for systematic observation of operator performance in nuclear training simulators which combines training and research. It is based on generally accepted theories of operator models and decision making developed at Riso and elsewhere. It makes explicitly available the data which experienced instructors implicitly use in their assessment of operator performance. This means that the feed-back/debriefing function of the training is facilitated, it becomes possible to use normal training sessions to obtain data which can be used in further theoretical studies of e.g. operator decision making, and the generalized description of operator performance may be used to evaluate the training program as such. The method for observation is designed in cooperation with the instructors so that it does not interfere with their normal work. It is based on a detailed prior analysis of experienced transients, leading to a description of an expected performance, and some transient-in-dependent observation schemes, which are used to characterize points where the actual performance deviates from the expected performance. The analysis of the observations takes place according to the structure of a general model of analysis developed from numerous studies of operator performance, in real life and in simulators.

    Robotic systems are often very complex and difficult to operate, especially as multiple robots are integrated to accomplish difficult tasks. In addition, training the operators of these complex robotic systems is time-consuming and costly. In this paper, a virtual reality based robotic control system is presented. The virtual reality system provides a means by which operators can operate, and be trained to operate, complex robotic systems in an intuitive, cost-effective way. Operator interaction with the robotic system is at a high, task-oriented, level. Continuous state monitoring prevents illegal robot actions and provides interactive feedback to the operator and real-time training for novice users.

    Endovascular surgery benefits patients because of its superior short convalescence and lack of damage to healthy tissue. However, such advantages require the operator to be equipped with dexterous skills for catheter manipulation without resulting in collateral damage. To achieve this goal, a training system is in high demand. A training system integrating a VR simulator and a haptic device has been developed within this context. The VR simulator is capable of providing visual cues which assist the novice for safe catheterization. In addition, the haptic device cooperates with VR simulator to apply sensations at the same time. The training system was tested by non-medical subjects over a five days training session. The performance was evaluated in terms of safety criteria and task completion time. The results demonstrate that operation safety is improved by 15.94% and task completion time is cut by 18.80 s maximum. Moreover, according to subjects' reflections, they are more confident in operation. The proposed training system constructs a comprehensive training environment that combines visualization and force sensation. Copyright © 2016 John Wiley & Sons, Ltd.

  10. A review of training research and virtual reality simulators for the da Vinci surgical system.

    Liu, May; Curet, Myriam

    2015-01-01

    PHENOMENON: Virtual reality simulators are the subject of several recent studies of skills training for robot-assisted surgery. Yet no consensus exists regarding what a core skill set comprises or how to measure skill performance. Defining a core skill set and relevant metrics would help surgical educators evaluate different simulators. This review draws from published research to propose a core technical skill set for using the da Vinci surgeon console. Publications on three commercial simulators were used to evaluate the simulators' content addressing these skills and associated metrics. An analysis of published research suggests that a core technical skill set for operating the surgeon console includes bimanual wristed manipulation, camera control, master clutching to manage hand position, use of third instrument arm, activating energy sources, appropriate depth perception, and awareness of forces applied by instruments. Validity studies of three commercial virtual reality simulators for robot-assisted surgery suggest that all three have comparable content and metrics. However, none have comprehensive content and metrics for all core skills. INSIGHTS: Virtual reality simulation remains a promising tool to support skill training for robot-assisted surgery, yet existing commercial simulator content is inadequate for performing and assessing a comprehensive basic skill set. The results of this evaluation help identify opportunities and challenges that exist for future developments in virtual reality simulation for robot-assisted surgery. Specifically, the inclusion of educational experts in the development cycle alongside clinical and technological experts is recommended.

    Acquisition of a full scope replica simulator represents an important achievement for Nuclear power Plant Krsko. Operating nuclear power plant systems is definitely a set of demanding and complex tasks. The most important element in the goal of assuring capabilities for handling such tasks is efficient training of operations personnel who manipulate controls in the main control room. Use of a simulator during the training process is essential and can not be substituted by other techniques. This article gives an overview of NPP Krsko licensed personnel training historical background, current experience and plans for future training activities. Reactor operator initial training lasts approximately two and a half years. Training is divided into several phases, consisting of theoretical and practical segments, including simulator training. In the past, simulator initial training and annual simulator retraining was contracted, thus operators were trained on non-specific full scope simulators. Use of our own plant specific simulator and associated infrastructure will have a significant effect on the operations personnel training process and, in addition, will also support secondary uses, with the common goal to improve safe and reliable plant operation. A regular annual retraining program has successfully started. Use of the plant specific simulator assures consistent training and good management oversight, enhances conformity of operational practices and supports optimization of operating procedures.

    Benkert, J.

    1986-01-01

    Basic Principles Simulators have the purpose of teaching general concepts, demonstrating and displaying the fundamental physical processes of a plant. They are used to illustrate theory to students and also to provide a preliminary training to the operators, to aquaint them with the basic dynamic interactions of the various systems during the normal operation of a plant, and to show the consequences of the most important and common transients and malfunctions. Basic principles simulators may vary in size from small desk cabinets to large panels. They represent with a certain detail the nuclear and thermohydraulic part of the plant. The availability of video displays allows to present detailed information about process parameters which are not shown on the control panels. In general the overall plant behaviour is represented well. Limitations are mostly found in the areas of logic and control. (orig./HP)

  18. Numerical Simulation of Vertical Random Vibration of Train-Slab Track-Bridge Interaction System by PEM

    2014-01-01

    Full Text Available The paper describes the numerical simulation of the vertical random vibration of train-slab track-bridge interaction system by means of finite element method and pseudoexcitation method. Each vehicle is modeled as four-wheelset mass-spring-damper system with two-layer suspension systems. The rail, slab, and bridge girder are modeled by three-layer elastic Bernoulli-Euler beams connected with each other by spring and damper elements. The equations of motion for the entire system are derived according to energy principle. By regarding rail irregularity as a series of multipoint, different-phase random excitations, the random load vectors of the equations of motion are obtained by pseudoexcitation method. Taking a nine-span simply supported beam bridge traveled by a train consisting of 8 vehicles as an example, the vertical random vibration responses of the system are investigated. Firstly, the suitable number of discrete frequencies of rail irregularity is obtained by numerical experimentations. Secondly, the reliability and efficiency of pseudoexcitation method are verified through comparison with Monte Carlo method. Thirdly, the random vibration characteristics of train-slab track-bridge interaction system are analyzed by pseudoexcitation method. Finally, applying the 3σ rule for Gaussian stochastic process, the maximum responses of train-slab track-bridge interaction system with respect to various train speeds are studied.

    In this paper, a new rehabilitation training system was developed to improve equilibrium sense control by combining virtual reality technology with a fixed exercise bicycle. In order to evaluate the effectiveness of the training system, twenty normal healthy adults participated as test subjects in the investigation of the influence of different the parameters on equilibrium sensory control. Several factors including path deviation, cycling time, cycling velocity, center of pressure were evaluated and analyzed quantitatively. Also, we investigated the usefulness of virtual feedback information for weight shift on the improvement of the effect of equilibrium training. After conducting repeated tests, we found improvements not only in of the ability to controlling balance and weight shift but also in the overall cycling capabilities such as cycling speed. Therefore, the new training system utilizing an excise bike and a virtual reality system is found to be effective on the improvement of equilibrium sense, and the technology we have developed seems to have a good prospect in the rehabilitation field.

    Operation training with full-scope simulators is effective to improve trainees operation competency. To obtain more effective results of simulator training, roles of the ''classroom operation training'' closely cooperated to simulator training are important. The ''classroom operation training'' is aimed at pre- and post-studies for operation knowledge related to operation training using full-scope simulators. We have been developing computer-based operation training tools which are used in classroom training sessions. As the first step, we developed the Simulator Training Replay System. This is an aiding tool in the classroom used to enhance trainees operation performance. This system can synchronously replay plant behavior on CRT display with operators action on a video monitor in the simulator training sessions. This system is used to review plant behavior - trainees response after simulator training sessions and to understand plant behavior - operation procedure before operation training. (author)

    2016-09-14

    Synchrophasor systems are being deployed in power systems throughout the North American Power Grid and there are plans to integrate this technology and its associated tools into Independent System Operator (ISO)/utility control room operations. A pre-requisite to using synchrophasor technologies in control rooms is for operators to obtain training and understand how to use this technology in real-time situations. The Phasor Simulator for Operator Training (PSOT) project objective was to develop, deploy and demonstrate a pre-commercial training simulator for operators on the use of this technology and to promote acceptance of the technology in utility and ISO/Regional Transmission Owner (RTO) control centers.

    While the potential of Virtual Environments (VE's) for training simulators has been recognized right from the start of the emergence of the technology, to date most VE systems that claim to be training simulators have been developed in an adhoc fashion. Based on requirements of the Royal Netherlands Army and Air Force, we have recently developed VE based training simulators following basic systems engineering practice. This paper reports on our approach in general, and specifically focuses on two examples. The first is a distributed VE system for training Forward Air Controllers (FAC's). This system comprises an immersive VE for the FAC trainee, as well as a number of other components, all interconnected in a network infrastructure utilizing the DIS/HLA standard protocols for distributed simulation. The prototype VE FAC simulator is currently being used in the training program of the Netherlands Integrated Air/Ground Operations School. Feedback from the users is being collected as input for a follow-on development activity. A second development is aimed at the evaluation of VE technology for training gunnery procedures with the Stinger man-portable air-defense system. In this project, a system is being developed that enables us to evaluate a number of different configurations with respect to both human and systems performance characteristics.

    1992-01-01

    Nuclear Electric is committed to the use of simulators to assist the training of power station operational staff. During the Public Enquiry into Sizewell B PWR Power Station a commitment was given to provide simulator training before the station was commissioned. To enable the training to be efficiently carried out, a full-scope, high-fidelity simulator has been installed in a new, purpose-built training centre located at Cliff Quay, Ipswich about 45 km from the station. In this context the term full scope implies that all plant systems controlled centrally are simulated and the term highfidelity signifies that the plant modelling is based in detailed physical models and is built up from the basic physics equations rather than being based on predetermined sequences. The facilities, computing system, software and modelling are described. (author)

    A full scope training simulator comprising of 109 plant systems of a 300 MWe PWR plant contracted by Pakistan Atomic Energy Commission (PAEC) from China is near completion. The simulator has its distinction in the sense that it will be ready prior to fuel loading. The models for the full scope training simulator have been developed under APROS (Advanced PROcess Simulator) environment developed by the Technical Research Center (VTT) and Imatran Voima (IVO) of Finland. The replicated control room of the plant is contracted from Shanghai Nuclear Engineering Research and Design Institute (SNERDI), China. The development of simulation models to represent all the systems of the target plant that contribute to plant dynamics and are essential for operator training has been indigenously carried out at PAEC. This multifunctional simulator is at present under extensive testing and will be interfaced with the control planes in March 1998 so as to realize a full scope training simulator. The validation of the simulator is a joint venture between PAEC and SNERDI. For the individual components and the individual plant systems, the results have been compared against design data and PSAR results to confirm the faithfulness of the simulator against the physical plant systems. The reactor physics parameters have been validated against experimental results and benchmarks generated using design codes. Verification and validation in the integrated state has been performed against the benchmark transients conducted using the RELAP5/MOD2 for the complete spectrum of anticipated transient covering the well known five different categories.

    Following the release of 10CFR55 operator licenses which specifies the requirements for simulation fidelity and control of nuclear power plant training simulators, many utilities have focused on procuring new certifiable plant specific simulators as well as enhancing their existing plant reference simulators. Enhancing fidelity of existing simulators to the level required by the guideline, includes, among other activities, upgrading the simulator's man machine interface and installation of advanced models. These advanced models utilize state-of-the-art mathematical tools, requiring a special computer complex and computer memory compatible with the existing simulator computer system. This paper illustrates some of the shortcomings associated with the existing simple models. The necessity and effects of advanced models to improve fidelity of training simulators are demonstrated

    1990-01-01

    This paper reports that the computer system for NPP personnel training was developed for training centers in the Soviet Union. The system should be considered as the first step in training, taking into account that further steps are to be devoted to part-task and full scope simulator training. The training room consists of 8-12 IBM PC/AT personal computers combined into a network. A trainee accesses the system in a dialor manner. Software enables the instructor to determine the trainee's progress in different subjects of the program. The quality of any trainee preparedness may be evaluated by Knowledge Control operation. Simplified dynamic models are adopted for separate areas of the program. For example, the system of neutron flux monitoring has a dedicated model. Currently, training, requalification and support of professional qualifications of nuclear power plant operators is being emphasized. A significant number of emergency situations during work are occurring due to operator errors. Based on data from September-October 1989, more than half of all unplanned drops in power and stoppages of power plants were due to operator error. As a comparison, problems due to equipment malfunction accounted for no more than a third of the total. The role of personnel, especially of the operators, is significant during normal operations, since energy production costs as well as losses are influenced by the capability of the staff. These facts all point to the importance of quality training of personnel

    2017-01-01

    The comparison of the developments obtained by training for aviation with the ones obtained by training for surgery highlights the efforts that are still required to define shared and validated training curricula for surgeons. This work focuses on robotic assisted surgery and the related training systems to analyze the current approaches to surgery training based on virtual environments. Limits of current simulation technology are highlighted and the systems currently on the market are compared in terms of their mechanical design and characteristics of the virtual environments offered. In particular the analysis focuses on the level of realism, both graphical and physical, and on the set of training tasks proposed. Some multimedia material is proposed to support the analysis and to highlight the differences between the simulations and the approach to training. From this analysis it is clear that, although there are several training systems on the market, some of them with a lot of scientific literature proving their validity, there is no consensus about the tasks to include in a training curriculum or the level of realism required to virtual environments to be useful.

  13. Experience with simulator training for emergency conditions

    International Nuclear Information System (INIS)

    1987-12-01

    The training of operators by the use of simulators is common to most countries with nuclear power plants. Simulator training programmes are generally well developed, but their value can be limited by the age, type, size and capability of the simulator. Within these limits, most full scope simulators have a capability of training operators for a range of design basis accidents. It is recognized that human performance under accident conditions is difficult to predict or analyse, particularly in the area of severe accidents. These are rare events and by their very nature, unpredictable. Of importance, therefore, is to investigate the training of operators for severe accident conditions, and to examine ways in which simulators may be used in this task. The International Nuclear Safety Advisory Group (INSAG) has reviewed this field and the associated elements of human behaviour. It has recommended that activities are concentrated on this area. Initially it is encouraging the following objectives: i) To train operators for accident conditions including severe accidents and to strongly encourage the development and use of simulators for this purpose; ii) To improve the man-machine interface by the use of computer aids to the operator; iii) To develop human performance requirements for plant operating staff. As part of this work, the IAEA convened a technical committee on 15-19 September 1986 to review the experience with simulator training for emergency conditions, to review simulator modelling for severe accident training, to examine the role of human cognitive behaviour modelling, and to review guidance on accident scenarios. A substantial deviation may be a major fuel failure, a Loss of Coolant Accident (LOCA), etc. Examples of engineered safety features are: an Emergency Core Cooling System (ECCS), and Containment Systems. This report was prepared by the participants during the meeting and reviewed further in a Consultant's Meeting. It also includes papers which were

    Virtual reality (VR) simulation has the potential to standardize surgical training for robotic surgery. We sought to evaluate all commercially available VR robotic simulators. A MEDLINE(®) literature search was performed of all applicable keywords. Available VR simulators were evaluated with regard to face, content, and construct validation. Additionally, a survey was e-mailed to all members of the Endourological Society, querying the pervasiveness of VR simulators in robotic surgical training. Finally, each company was e-mailed to ask for a price quote for their respective system. There are four VR robotic surgical simulators currently available: RoSS™, dV-Trainer™, SEP Robot™, and da Vinci(®) Skills Simulator™. Each system is represented in the literature and all possess varying degrees of face, content, and construct validity. Although all systems have basic skill sets with performance analysis and metrics software, most do not contain procedural components. When evaluating the results of our survey, most respondents did not possess a VR simulator although almost all believed there to be great potential for these devices in robotic surgical training. With the exception of the SEP Robot, all VR simulators are similar in price. VR simulators have a definite role in the future of robotic surgical training. Although the simulators target technical components of training, their largest impact will be appreciated when incorporated into a comprehensive educational curriculum.

    Simulation in healthcare is becoming increasingly used. This review will spotlight some of the uses of simulation in healthcare training. Previously, evaluation of simulation training was typically from evaluations from trainees. Recent articles, however, have linked simulation training to actual patient outcomes and demonstrated skill retention up to 1 year. Objective measurements have demonstrated positive effects on healthcare education, have been successfully used in high stakes examinations, and have uncovered systems and patient safety issues. This article will review some recent studies showing how simulation can have a positive effect on patient outcomes and skill retention, uncover systems issues related to patient safety, and how simulation can be used in credentialing, and other high stakes examinations.

    A peripatetic approach to technical training is being adopted by Nuclear Electric in the use with its plants to adopt a compact, mobile simulator for certain training applications. Unlike the fixed digital power plant simulators housed at the company's Oldbury Nuclear Training Center near Bristol and the Cliff Quay Training Centre in Ipswich, these are designed to travel around the country to server users. The first of the mobile simulators will be used to train operators in the safe switching of high voltage apparatus between power stations and the UK National Grid transmission system. The simulator comprises a four-piece, four-position suite of equipment, providing power station and sub-station control room panels and a grid control module, all of which are managed by a tutor's station. It is driven by six IBM PC compatibles - four 486 and two 386 machines - operating under MS-DOS 5 and to a program written in Turbo Pascal. The simulator packs away inside a trailer, which can then be towed behind the tutor's car to its next location. One person can unload and set up the equipment in 30 minutes. Fully staffed, the simulator can be used with up to six operators or for individual tuition at each work station. (author)

    The proposed revisions to ANS 3.5-1985 (Section 5) require Utilities to establish a simulator Configuration Management System (CMS). The proposed CMS must be capable of: Establishing and maintaining a simulator design database. Identifying and documenting differences between the simulator and its reference plant. Tracking the resolution of identified differences. Recording data to support simulator certification, testing and maintenance. This paper discusses a CMS capable of meeting the proposed requirements contained in ANS 3.5. The system will utilize a personal computer and a relational database management software to construct a simulator design database. The database will contain records to all reference nuclear plant data used in designing the simulator, as well as records identifying all the software, hardware and documentation making up the simulator. Using the relational powers of the database management software, reports will be generated identifying the impact of reference plant changes on the operation of the simulator. These reports can then be evaluated in terms of training needs to determine if changes are required for the simulator. If a change is authorized, the CMS will track the change through to its resolution and then incorporate the change into the simulator design database

    The era of the International Space Station (ISS) has finally arrived, providing researchers on Earth a unique opportunity to study long-term effects of weightlessness and the space environment on structures, materials and living systems. Many of the physical, biological and material science experiments planned for ISS will require significant input and expertise from astronauts who must conduct the research, follow complicated assay procedures and collect data and samples in space. Containment is essential for Much of this work, both to protect astronauts from potentially harmful biological, chemical or material elements in the experiments as well as to protect the experiments from contamination by air-born particles In the Space Station environment. When astronauts must open the hardware containing such experiments, glovebox facilities provide the necessary barrier between astronaut and experiment. On Earth, astronauts are laced with the demanding task of preparing for the many glovebox experiments they will perform in space. Only a short time can be devoted to training for each experimental task and gl ovebox research only accounts for a small portion of overall training and mission objectives on any particular ISS mission. The quality of the research also must remain very high, requiring very detailed experience and knowledge of instrumentation, anatomy and specific scientific objectives for those who will conduct the research. This unique set of needs faced by NASA has stemmed the development of a new computer simulation tool, the Virtual Glovebox (VGB), which is designed to provide astronaut crews and support personnel with a means to quickly and accurately prepare and train for glovebox experiments in space.

    The first training simulator for nuclear power plant personnel in Germany was commissioned twenty-five years ago. The strategy of training by simulators was developed and pursued consistently and continuously in order to ensure sound training of nuclear power plant personnel. The present thirteen simulators cover a broad range of plants. A systematic training concept also helps to ensure a high level of competence and permanent qualification of plant personnel. The anniversary was marked by a festive event at which Erich K.

    For the recruitment, training and position qualification of the simulator instructors and feedback of training effect, the management approaches are formulated in 'The System for Simulator Training and Licensing Examination of Daya Bay Nuclear Power Station Operators'. The concrete requirements on the professional knowledge, work experience and foreign language ability of a simulator instructor are put forward. The process of instructor training is designed. The training items include the trainer training, pedagogy training, time management training, operation activities training during outage of unit, 'shadow' training and on-the-jot training on simulator courses. Job rotation is realized between simulator instructor and licensing personnel on site. New simulator instructor must pass the qualification identification. After a duration of 2 years, re-qualification has to be carried out. On the basis of the operator training method introduced from EDF (electricite De France), some new courses are developed and the improvement on the initial training, retaining courses, the technical support and the experience feedback by using the simulator is done also.

    Corporate aviation relies heavily on simulation to meet training and evaluation requirements. It appreciates the savings in fuel, money, noise, and time, and the added safety it provides. Also, simulation provides opportunities to experience many emergencies that cannot be safely practiced in the aircraft. There is a need to focus on the advantages of simulator training over aircraft training and to provide appropriate changes in the regulations to allow the community to make it possible for users to take full advantage of simulation.

  6. Common modelling approaches for training simulators for nuclear power plants

    International Nuclear Information System (INIS)

    1990-02-01

    Training simulators for nuclear power plant operating staff have gained increasing importance over the last twenty years. One of the recommendations of the 1983 IAEA Specialists' Meeting on Nuclear Power Plant Training Simulators in Helsinki was to organize a Co-ordinated Research Programme (CRP) on some aspects of training simulators. The goal statement was: ''To establish and maintain a common approach to modelling for nuclear training simulators based on defined training requirements''. Before adapting this goal statement, the participants considered many alternatives for defining the common aspects of training simulator models, such as the programming language used, the nature of the simulator computer system, the size of the simulation computers, the scope of simulation. The participants agreed that it was the training requirements that defined the need for a simulator, the scope of models and hence the type of computer complex that was required, the criteria for fidelity and verification, and was therefore the most appropriate basis for the commonality of modelling approaches. It should be noted that the Co-ordinated Research Programme was restricted, for a variety of reasons, to consider only a few aspects of training simulators. This report reflects these limitations, and covers only the topics considered within the scope of the programme. The information in this document is intended as an aid for operating organizations to identify possible modelling approaches for training simulators for nuclear power plants. 33 refs

The paper addresses the Dynamic interaction between different domains: internal combustion engine. exhaust after treatment devices, electric components. mechanical drive train. cooling circuit system and corresponding control units. To achieve a good ratio between accuracy. predictability and computational speed of the model an innovative time domain decoupling is presented, which is based on applying domain specific integration steps to ditferent domains and subsequent consistent cross-domain coupling ol’thefluxes. In addition, a computationally efficient frunieveork for transporting active and passive gaseous species is introduced to combine computational efficiency with the need for modeling pollutant transport in the gas path. The applicability and versatility of the mechanistic system level simulations model is presented through analyses of transient phenomena caused by the high interdependency of the sub-systems, i.e. domains.

    Full Text Available Abstract Background Basic clinical skills training in the Japanese medical education system has traditionally incorporated on-the-job training with patients. Recently, the complementary use of simulation techniques as part of this training has gained popularity. It is not known, however, whether the participants view this new type of education program favorably; nor is the impact of this program known. In this study we developed a new simulation-based training program in phlebotomy for new medical residents and assessed their satisfaction with the program Methods The education program comprised two main components: simulator exercise sessions and the actual drawing of blood from other trainees. At the end of the session, we surveyed participant sentiment regarding the program. Results There were 43 participants in total. In general, they were highly satisfied with the education program, with all survey questions receiving scores of 3 or more on a scale of 1–5 (mean range: 4.3 – 4.8, with 5 indicating the highest level of satisfaction. Additionally, their participation as a 'patient' for their co-trainees was undertaken willingly and was deemed to be a valuable experience. Conclusion We developed and tested an education program using a simulator for blood collection. We demonstrated a high satisfaction level among the participants for this unique educational program and expect that it will improve medical training, patient safety, and quality of care. The development and dissemination of similar educational programs involving simulation for other basic clinical skills will be undertaken in the future.

    Surgical simulation is a promising technique for training of laparoscopic surgery. Computer based simulation provides not only a cost effective alternative to traditional training but also a way to assess the surgeons performance. In this paper, we present a haptic simulator that allows for training and assessment of basic laparoscopic skills. The skills trained are modeled around a cholecystectomy procedure and include bi-manual dissection, clips setting, catheter insertion and cutting. The system uses accurate anatomic models of the organs involved in the procedure. This combined with effective methods for soft tissue deformation and haptic feedback, giving the surgeon a precise feeling of the interaction between organs and surgical instruments, provides a realistic training environment. The system has been designed with procedural training in mind and by putting together the individual tasks it will be possible to train on performing a complete cholecystectomy procedure.

  13. Simulation of Ground-Water Flow in the Irwin Basin Aquifer System, Fort Irwin National Training Center, California

    2003-01-01

    Ground-water pumping in the Irwin Basin at Fort Irwin National Training Center, California resulted in water-level declines of about 30 feet from 1941 to 1996. Since 1992, artificial recharge from wastewater-effluent infiltration and irrigation-return flow has stabilized water levels, but there is concern that future water demands associated with expansion of the base may cause a resumption of water-level declines. To address these concerns, a ground-water flow model of the Irwin Basin was developed to help better understand the aquifer system, assess the long-term availability and quality of ground water, and evaluate ground-water conditions owing to current pumping and to plan for future water needs at the base. Historical data show that ground-water-level declines in the Irwin Basin between 1941 and 1996, caused the formation of a pumping depression near the pumped wells, and that recharge from the wastewater-treatment facility and disposal area caused the formation of a recharge mound. There have been two periods of water-level recovery in the Irwin Basin since the development of ground water in this basin; these periods coincide with a period of decreased pumpage from the basin and a period of increased recharge of water imported from the Bicycle Basin beginning in 1967 and from the Langford Basin beginning in 1992. Since 1992, artificial recharge has exceeded pumpage in the Irwin Basin and has stabilized water-level declines. A two-layer ground-water flow model was developed to help better understand the aquifer system, assess the long-term availability and quality of ground water, and evaluate ground-water conditions owing to current pumping and to plan for future water needs at the base. Boundary conditions, hydraulic conductivity, altitude of the bottom of the layers, vertical conductance, storage coefficient, recharge, and discharge were determined using existing geohydrologic data. Rates and distribution of recharge and discharge were determined from

    This paper describes an operator training simulator for BWR nuclear power plants which went into service recently. The simulator is a full scope replica type simulator which faithfully replicates the control room environment of the reference plant with six main control panels and twelve auxiliary ones. In comparison with earlier simulators, the scope of the simulation is significantly extended in both width and depth. The simulation model is also refined in order to include operator training according to sympton-based emergency procedure guidelines to mitigate the results in accident cases. In particular, the core model and the calculational model of the radiation intensity distribution, if radioactive materials were released, are improved. As for simulator control capabilities by which efficient and effective training can be achieved, various advanced designs are adopted allowing easy use of the simulators. (author)

    As one of the important factors for maintaining the high capacity ratio in Japanese nuclear power stations, the contribution of excellent operators is pointed out. BWR Operation Training Center has trained many operators using two full scope simulators for operation training modeling BWRs. But in order to meet the demands of the recent increase of training needs and the upgrading of the contents, it was decided to install the third simulator, and Hitachi Ltd. received the order to construct the main part, and delivered it. This simulator obtained the good reputation as its range of simulation is wide, and the characteristics resemble very well those of the actual plants. Besides, various new designs were adopted in the control of the simulator, and its handling became very easy. Japanese nuclear power plants are operated at constant power output, and the unexpected stop is very rare, therefore the chance of operating the plants by operators is very few. Accordingly, the training using the simulators which can simulate the behavior of the plants with computers, and can freely generate abnormal phenomena has become increasingly important. The mode and positioning of the simulators for operation training, the full scope simulator BTC-3 and so on are reported. (K.I.)

    Simulation-based team training (SBTT) in healthcare is gaining acceptance. Guidelines for appropriate use of SBTT exist, but the evidence base remains limited. Insights from other academic disciplines with sophisticated models of team working may point to opportunities to build on current frameworks applied to team training in healthcare. The purpose of this consensus statement is threefold: (1) to highlight current best practices in designing SBTT in healthcare and to identify gaps in current implementation; (2) to explore validated concepts and principles from relevant academic disciplines and industries; and (3) to identify potential high-yield areas for future research and development. We performed a selective review and critical synthesis of literature in healthcare simulation related to team learning as well as from other relevant disciplines such as psychology, business, and organizational behavior. We discuss appropriate use of SBTT and identify gaps in the literature. Healthcare educators should apply rigorous curriculum development processes and generate learning opportunities that address the interrelated conceptual levels of team working by addressing learning needs at the level of the individual, the team, the organization, and the healthcare system. The interplay between these conceptual levels and their relative importance to team-based learning should be explored and described. Instructional design factors and contextual features that impact the effect of SBTT should be studied. Further development of validated assessment tools of team performance relevant to professional practice is a high priority and is essential to provide formative, summative, and diagnostic feedback and evaluation of SBTT. Standardized reporting of curriculum design and debriefing approaches, although difficult, would help move the field forward by allowing educators to characterize effective SBTT instruction. Much work is needed to establish a robust and defensible evidence

    Since the first use of robotic surgical system in 2000, the robot-assisted technology has gained wide popularity throughout the world. Robot-assisted surgical training is a complex issue that requires significant efforts from students and teacher. During the last two decades, simulation-based training had received active development due to wide-spread occurrence and popularization of laparoscopic and robot-assisted surgical techniques. We performed a systematic review to identify the currently available simulators for robot-assisted surgery. We searched the Medline and Pubmed, English sources of literature data, using the following key words and phrases: "robotics", "robotic surgery", "computer assisted surgery", "simulation", "computer simulation", "virtual reality", "surgical training", and "surgical education". There were identified 565 publications, which meet the key words and phrases; 19 publications were selected for the final analysis. It was established that simulation-based training is the most promising teaching tool that can be used in the training of the next generation robotic surgeons. Today the use of simulators to train surgeons is validated. Price of devices is an obvious barrier for inclusion in the program for training of robotic surgeons, but the lack of this tool will result in a sharp increase in the duration of specialists training.

    Simulation education is an important part of health care education and training. There is growing evidence to support the usefulness of simulation, especially in training for infrequently occurring situations, such as medical emergencies seen by dental practitioners. There are, however, few data on the longer term effects of simulation, including usefulness, relevance, emotional effect and ability to affect changes to daily practice. Dentists and dental nurses who had undergone simulation training in medical emergencies for dental sedation practitioners undertook a semi-structured interview about their perception of the simulation experience. They explored recollection of the experience and its emotional weight, perception of usefulness and relevance, specific learning outcomes and changes to practice prompted by the simulation session. Participants reported finding the simulation sessions worthwhile, realistic, challenging and almost universally emotionally positive. In situ simulation training was particularly well received, both in terms of realism, as well as identifying system flaws in emergency drugs and equipment. Participants reported gaining both increased clinical knowledge and human factors skills, which were reflected in subsequent changes to their practice. There are few data on the longer term effects of simulation DISCUSSION: Our results support the usefulness and applicability of simulation education to training in medical emergencies for dental sedation practitioners. In particular, specific benefits reported from in situ sessions and in human factors concepts will prompt us to review the structure of our teaching to maximise the benefit to participants. © 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

    Aim: Simulation forms an increasingly vital component of clinical skills development in a wide range of professional disciplines. Simulation of clinical techniques and equipment is designed to better prepare students for placement by providing an opportunity to learn technical skills in a “safe” academic environment. In radiotherapy training over the last decade or so this has predominantly comprised treatment planning software and small ancillary equipment such as mould room apparatus. Recent virtual reality developments have dramatically changed this approach. Innovative new simulation applications and file processing and interrogation software have helped to fill in the gaps to provide a streamlined virtual workflow solution. This paper outlines the innovations that have enabled this, along with an evaluation of the impact on students and educators. Method: Virtual reality software and workflow applications have been developed to enable the following steps of radiation therapy to be simulated in an academic environment: CT scanning using a 3D virtual CT scanner simulation; batch CT duplication; treatment planning; 3D plan evaluation using a virtual linear accelerator; quantitative plan assessment, patient setup with lasers; and image guided radiotherapy software. Results: Evaluation of the impact of the virtual reality workflow system highlighted substantial time saving for academic staff as well as positive feedback from students relating to preparation for clinical placements. Students valued practice in the “safe” environment and the opportunity to understand the clinical workflow ahead of clinical department experience. Conclusion: Simulation of most of the radiation therapy workflow and tasks is feasible using a raft of virtual reality simulation applications and supporting software. Benefits of this approach include time-saving, embedding of a case-study based approach, increased student confidence, and optimal use of the clinical environment

    The prototype fast breeder reactor, Monju, has been performing deliberately the operator training which is composed of the regulated training required by the government and the self-training. The training used a full scope type simulator (MARS: Monju Advanced Reactor Simulator) plays an important role among of the above mentioned trainings and greatly contributes to the Monju operator training for Monju restarting. This report covers the activities of Monju operator training in 2002 FY, i.e. the training results and the remodeling working of the MARS in progress since 1999. (1) Eight simulator training courses were carried out 46 times and 180 trainees participated. Additionally, both the regulated training and self-training were held total 10 times by attended 34 trainees, as besides simulator training. (2) Above training data was reduced compare with the last year's data (69 times (338 trainees)) due to the indispensable training courses in Monju operator training were changed by reorganized operator's number and decreasing of training times owing to remodeling working of the simulator was conducted. (3) By means of upgrading of the MARS completed in 2002 FY, its logic arithmetic time was became speedier and its instructing function was improved remarkably, thus, the simulator training was became to be more effective. Moreover, it's planning to do both remodeling in the next year as the final working: remodeling of reactor core model with the aim of improvement simulating accuracy and corresponding to the sodium leakage measures.

    Teamwork training constitutes one of the core approaches for moving healthcare systems toward increased levels of quality and safety, and simulation provides a powerful method of delivering this training, especially for face-paced and dynamic specialty areas such as Emergency Medicine. Team performance measurement and evaluation plays an integral role in ensuring that simulation-based training for teams (SBTT) is systematic and effective. However, this component of SBTT systems is overlooked frequently. This article addresses this gap by providing a review and practical introduction to the process of developing and implementing evaluation systems in SBTT. First, an overview of team performance evaluation is provided. Second, best practices for measuring team performance in simulation are reviewed. Third, some of the prominent measurement tools in the literature are summarized and discussed relative to the best practices. Subsequently, implications of the review are discussed for the practice of training teamwork in Emergency Medicine.

    While the knowledge required of residents training in orthopedic surgery continues to increase, various factors, including reductions in work hours, have resulted in decreased clinical learning opportunities. Recent work suggests residents graduate from their training programs without sufficient exposure to key procedures. In response, simulation is increasingly being incorporated into training programs to supplement clinical learning. This paper reviews the literature to explore whether skills learned in simulation-based settings results in improved clinical performance in orthopedic surgery trainees. A scoping review of the literature was conducted to identify papers discussing simulation training in orthopedic surgery. We focused on exploring whether skills learned in simulation transferred effectively to a clinical setting. Experimental studies, systematic reviews, and narrative reviews were included. A total of 15 studies were included, with 11 review papers and four experimental studies. The review articles reported little evidence regarding the transfer of skills from simulation to the clinical setting, strong evidence that simulator models discriminate among different levels of experience, varied outcome measures among studies, and a need to define competent performance in both simulated and clinical settings. Furthermore, while three out of the four experimental studies demonstrated transfer between the simulated and clinical environments, methodological study design issues were identified. Our review identifies weak evidence as to whether skills learned in simulation transfer effectively to clinical practice for orthopedic surgery trainees. Given the increased reliance on simulation, there is an immediate need for comprehensive studies that focus on skill transfer, which will allow simulation to be incorporated effectively into orthopedic surgery training programs.

    The continuous pipeline operators training and certification of the TRANSPETRO's Pipeline National Operations Control Center (CNCO) is an essential task aiming the efficiency and safety of the oil and derivatives transport operations through the Brazilian pipeline network. For this objective, a hydraulic simulator is considered an excellent tool that allows the creation of different operational scenarios for training the pipeline hydraulic behavior as well as for testing the operator's responses to normal and abnormal real time operational conditions. The hydraulic simulator is developed based on a pipeline simulation software that supplies the hydraulic responses normally acquired from the pipeline remote units in the field. The pipeline simulation software has a communication interface system that sends and receives data to the SCADA supervisory system database. Using the SCADA graphical interface to create and to customize human machine interfaces (HMI) from which the operator/instructor has total control of the pipeline/system and instrumentation by sending commands. Therefore, it is possible to have realistic training outside of the real production systems, while acquiring experience during training hours with the operation of a real pipeline. A pilot Project was initiated at TRANSPETRO - CNCO targeting to evaluate the hydraulic simulators advantages in pipeline operators training and certification programs. The first part of the project was the development of three simulators for different pipelines. The excellent results permitted the project expansion for a total of twenty different pipelines, being implemented in training programs for pipelines presently operated by CNCO as well as for the new ones that are being migrated. The main objective of this paper is to present an overview of the implementation process and the development of a training environment through a pipe simulation environment using commercial software.

    Simulation is increasingly recognised as a valuable tool in training tomorrow's doctors. This technology has the potential to improve patient safety and address some of the challenges posed by recent changes in doctors' training, yet the uptake has been slow in the majority of institutions. In our own centre, we noted existing equipment was used infrequently. We sought to address this problem through the development of a 1-day training course in simulation (SIM) and basic interventional skills aimed at trainees from across different endovascular specialties. A 1-day course for trainees in cardiology, interventional radiology and vascular surgery was piloted. A variety of endovascular simulators were used to teach core skills common to all three specialties, under the umbrella theme of safe access, safe navigation and safe closure. Independent continuing use of SIM-based training was encouraged. Trainee and faculty member experiences of SIM training in a cross-specialty environment were explored by interview and online questionnaire. Thirty-six trainees completed the pilot training course. Feedback was almost universally positive, with all trainees agreeing that SIM was useful in achieving the course's objectives, and that they would recommend the course to a colleague. Cross-specialty training was viewed positively by trainees and trainers alike, with benefits identified in knowledge and skills sharing, as well as fostering better clinical collaboration. SIM-based training was perceived as useful in promoting patient safety, and is considered to be a desirable component of future training. We present a SIM-based model that achieves economies of scale by delivering common skill-set training for doctors from different specialties. Through our experiences piloting this course we discuss how the recognised barriers to adopting this new technology may be addressed and offer insights into how SIM may be integrated into existing training programmes. © 2014 John Wiley

    The principal purpose of this publication is to provide a broad overview of the technology that is relevant to the design of aviation training systems and of the techniques applicable to the development, use, and evaluation of those systems. The issues addressed in our 11 chapters are, for the most part, those that would be expected to surface in any informed discussion of the major characterizing elements of aviation training systems. Indeed, many of the same facets of vertical-flight training discussed were recognized and, to some extent, dealt with at the 1991 NASA/FAA Helicopter Simulator Workshop. These generic topics are essential to a sound understanding of training and training systems, and they quite properly form the basis of any attempt to systematize the development and evaluation of more effective, more efficient, more productive, and more economical approaches to aircrew training. Individual chapters address the following topics: an overview of the vertical flight industry: the source of training requirements; training and training schools: meeting current requirements; training systems design and development; transfer of training and cost-effectiveness; the military quest for flight training effectiveness; alternative training systems; training device manufacturing; simulator aero model implementation; simulation validation in the frequency domain; cockpit motion in helicopter simulation; and visual space perception in flight simulators.

    Full Text Available We developed a train operation simulation tool to inspect a train operation plan. In applying an improved Petri Net, the train was regarded as a token, and the line and station were regarded as places, respectively, in accordance with the high-speed train operation characteristics and network function. Location change and running information transfer of the high-speed train were realized by customizing a variety of transitions. The model was built based on the concept of component combination, considering the random disturbance in the process of train running. The simulation framework can be generated quickly and the system operation can be completed according to the different test requirements and the required network data. We tested the simulation tool when used for the real-world Wuhan to Guangzhou high-speed line. The results showed that the proposed model can be developed, the simulation results basically coincide with the objective reality, and it can not only test the feasibility of the high-speed train operation plan, but also be used as a support model to develop the simulation platform with more capabilities.

    The need to develop new methods of surgical training combined with advances in computing has led to the development of virtual reality surgical simulators. The PERC Mentor(TM) is designed to train the user in percutaneous renal collecting system access puncture. This study aimed to validate the use of this kind of simulator, in percutaneous renal access training. Twenty-one urologists were enrolled as trainees to learn a fluoroscopy-guided percutaneous renal accessing technique. An assigned percutaneous renal access procedure was immediately performed on the PERC Mentor(TM) after watching instruction video and an analog operation. Objective parameters were recorded by the simulator and subjective global rating scale (GRS) score were determined. Simulation training followed and consisted of 2 hours daily training sessions for 2 consecutive days. Twenty-four hours after the training session, trainees were evaluated performing the same procedure. The post-training evaluation was compared to the evaluation of the initial attempt. During the initial attempt, none of the trainees could complete the appointed procedure due to the lack of experience in fluoroscopy-guided percutaneous renal access. After the short-term training, all trainees were able to independently complete the procedure. Of the 21 trainees, 10 had primitive experience in ultrasound-guided percutaneous nephrolithotomy. Trainees were thus categorized into the group of primitive experience and inexperience. The total operating time and amount of contrast material used were significantly lower in the group of primitive experience versus the inexperience group (P = 0.03 and 0.02, respectively). The training on the virtual reality simulator, PERC Mentor(TM), can help trainees with no previous experience of fluoroscopy-guided percutaneous renal access to complete the virtual manipulation of the procedure independently. This virtual reality simulator may become an important training and evaluation tool in

    For reasons which are stated, the Hunterston-B nuclear power station automatic control system includes a manual over-ride facility. It is therefore essential for the station engineers to be trained to recognise and control all feasible modes of plant and logic malfunction. A training simulator has been built which consists of a replica of the shutdown monitoring panel in the Central Control Room and is controlled by a mini-computer. This paper highlights the computer aspects of the simulator and relevant derived experience, under the following headings: engineering background; shutdown sequence equipment; simulator equipment; features; software; testing; maintenance.

    RighTSTEP is a suite of simulation software which has been initially designed to facilitate upgrade of Ontario Hydro's full-scope simulators, but is also adaptable to a variety of other roles. it is presently being commissioned at Bruch A Training Simulator and has seen preliminary use in desktop and classroom roles. Because of the flexibility of the system, we anticipate it will see common use in the corporation for full-scope simulation roles. A key reason for developing RighTSTEP (Real Time Simulator Technology Extensible and Portable) was the need to modernize and upgrade the full-scope training simulator while protecting the investment in modelling code. This modelling code represents the end product of 18 years of evolution from the beginning of its development in 1979. Bringing this modelling code to a modern and more useful framework - the combination of simulator host, operating system, and simulator operating system - also could provide many spin-off benefits. The development (and first implementation) of the righTSTEP system was cited for saving the corporation 5.6M$ and was recognized by a corporate New Technology Award last year. The most important spin-off from this project has been the desktop version of the full-scope simulator. The desktop simulator uses essentially the same software as does its full-scope counterpart, and may be used for a variety of new purposes. Classroom and individual simulator training can now be easily accommodated since a desktop simulator is both affordable and relatively ease to use. Further, a wide group of people can be trained using the desktop simulator: by contrast the full-scope simulators were almost exclusively devoted to front-line operating staff. The desktop is finding increasing use in support of engineering applications, resulting from its easy accessibility, breadth of station systems represented, and tools for analysis and viewing. As further plant models are made available on the new simulator platform and

    Roberto Rocha e Silva

    Full Text Available Abstract Objective: Introduce the low-cost and easy to purchase simulator without biological material so that any institution may promote extensive cardiovascular surgery training both in a hospital setting and at home without large budgets. Methods: A transparent plastic box is placed in a wooden frame, which is held by the edges using elastic bands, with the bottom turned upwards, where an oval opening is made, "simulating" a thoracotomy. For basic exercises in the aorta, the model presented by our service in the 2015 Brazilian Congress of Cardiovascular Surgery: a silicone ice tray, where one can train to make aortic purse-string suture, aortotomy, aortorrhaphy and proximal and distal anastomoses. Simulators for the training of valve replacement and valvoplasty, atrial septal defect repair and aortic diseases were added. These simulators are based on sewage pipes obtained in construction material stores and the silicone trays and ethyl vinyl acetate tissue were obtained in utility stores, all of them at a very low cost. Results: The models were manufactured using inert materials easily found in regular stores and do not present contamination risk. They may be used in any environment and maybe stored without any difficulties. This training enabled young surgeons to familiarize and train different surgical techniques, including procedures for aortic diseases. In a subjective assessment, these surgeons reported that the training period led to improved surgical techniques in the surgical field. Conclusion: The model described in this protocol is effective and low-cost when compared to existing simulators, enabling a large array of cardiovascular surgery training.

    Every employee of a power plant contributes with his individual expertise to the success of the enterprise. Certainly personal skills of employees differ from each other as well as power plants are different. With respect to effective simulator training this means that no two simulator training courses can be identical. To exactly meet the requirements of our customers KWS has developed modules for simulation training courses. Each module represents either a technical subject or addresses a topic in the field of soft skills. An accurately fitting combination of several of these modules to the needs of our customers allows for most efficient simulator training courses. (orig.)

    The use of simulators as educational tools for medical procedures is spreading rapidly and many efforts have been made for their implementation in gastrointestinal endoscopy training. Endoscopy simulation training has been suggested for ascertaining patient safety while positively influencing the trainees’ learning curve. Virtual simulators are the most promising tool among all available types of simulators. These integrated modalities offer a human-like endoscopy experience by combining virtual images of the gastrointestinal tract and haptic realism with using a customized endoscope. From their first steps in the 1980s until today, research involving virtual endoscopic simulators can be divided in two categories: investigation of the impact of virtual simulator training in acquiring endoscopy skills and measuring competence. Emphasis should also be given to the financial impact of their implementation in endoscopy, including the cost of these state-of-the-art simulators and the potential economic benefits from their usage. Advances in technology will contribute to the upgrade of existing models and the development of new ones; while further research should be carried out to discover new fields of application.

    The most significant features of the man-machine interface for CANDU power stations are the extensive use of computer-driven colour graphics displays and the small number of manual controls. The man-machine interface in CANDU stations is designed to present the operator with concise, easy-to-understand information. Future developments in the use of computers in safety shutdown systems, and the use of data highway technologies in plant regulating systems will present special requirements and new opportunities in the application of human factors engineering to the control room. Good man-machine interaction depends on operator training as much as on control room design. In Canada computerized training simulators, which indicate plant response to operator action, are being introducted for operator training. Such simulators support training in normal operation of all plant systems and also in the fault management tasks following malfunctions

    The Fundamentals of Endoscopic Surgery (FES) exam is required for American Board of Surgery certification. The purpose of this study was to develop performance standards for a simulation-based mastery learning (SBML) curriculum for the FES performance exam using the Endoscopy Training System (ETS). Experienced endoscopists from multiple institutions and specialties performed each ETS task (scope manipulation (SM), tool targeting (TT), retroflexion (RF), loop management (LM), and mucosal inspection (MI)) with scores used to develop performance standards for a SBML training curriculum. Trainees completed the curriculum to determine feasibility, and effect on FES performance. Task specific training standards were determined (SM-121sec, TT-243sec, RF-159sec, LM-261sec, MI-180-480sec, 7 polyps). Trainees required 29.5 ± 3.7 training trials over 2.75 ± 0.5 training sessions to complete the SBML curriculum. Despite high baseline FES performance, scores improved (pre 73.4 ± 7, post 78.1 ± 5.2; effect size = 0.76, p > 0.1), but this was not statistically discernable. This SBML curriculum was feasible and improved FES scores in a group of high performers. This curriculum should be applied to novice endoscopists to determine effectiveness for FES exam preparation.

    The paper aims to present the results of the Cernavoda NPP Training Department modernization project. In order to achieve a knowledge society training system, in the first stage of the project a Computer Based Training (CBT) or E-Learning software platform and several CBT objects/courses have been implemented. The conceived solution is called CBTCenter which is a complete E-Learning and CBT system, offering a variety of teaching and learning tools and services to its users. CBT and/or E-Learning always mean two things: a software platform and content authoring. Ideally, a software platform should be able to import any type of flat documentation and integrate it into a structured database which keeps track of pedagogically meaningful information like the student's progress in studying materials, tests and quizzes, grades, etc. At the same time, the materials, the study and the tests have to be organized around certain objectives which play the role of guidelines during the entire educational activity. An example of such a course which has been successfully integrated into CBTCenter is Labour safety - code name BB-001. The implementation of the CBT technology at NPP Cernavoda Training Department has brought several advantages: the technology improves overall communication between all individuals which take part in the educational process; the classroom space problem has been considerably reduced; students can access training materials from their own desk using the NPP intranet; the logistics problems will decrease with the conversion of more and more conventional courses and materials into CBT objects/courses.

    The most operator support systems including the training simulator have been developed to assist the operator and they cover from normal operation to emergency operation. For the severe accident, the overall architecture for severe accident management is being developed in some developed countries according to the development of severe accident management guidelines which are the skeleton of severe accident management architecture. In Korea, the severe accident management guideline for KSNP was recently developed and it is expected to be a central axis of logical flow for severe accident management. There are a lot of uncertainties in the severe accident phenomena and scenarios and one of the major issues for developing a operator support system for a severe accident is the reduction of these uncertainties. In this paper, the severe accident management advisory system with training simulator, SAMAT, is developed as all available information for a severe accident are re-organized and provided to the management staff in order to reduce the uncertainties. The developed system includes the graphical display for plant and equipment status, the previous research results by knowledge-base technique, and the expected plant behavior using the severe accident training simulator. The plant model used in this paper is oriented to severe accident phenomena and thus can simulate the plant behavior for a severe accident. Therefore, the developed system may make a central role of the information source for decision-making for a severe accident management, and will be used as the training simulator for severe accident management

    Full Text Available Background: Extracorporeal membrane oxygenation (ECMO is a complex treatment. Despite this, there are a lack of training programs designed to develop relevant clinical and nonclinical skills required for ECMO specialists. The aim of the current study was to describe the design, implementation and evaluation of a 1-day simulation course for delivering training in ECMO. Methods: A 1-day simulation course was developed with educational and intensive care experts. First, the delegates received a lecture on the principles of simulation training and the importance of human factors. This was, followed by a practical demonstration and discussion of the ECMO circuit, console components, circuit interactions effects and potential complications. There were then five ECMO simulation scenarios with debriefing that covered technical and nontechnical issues. The course culminated in a knowledge-based assessment. Course outcomes were assessed using purpose-designed questionnaires. Results: We held 3 courses with a total of 14 delegates (9 intensive care nurses, 3 adult intensive care consultants and 2 ECMO technicians. Following the course, 8 (57% gained familiarity in troubleshooting an ECMO circuit, 6 (43% increased their familiarity with the ECMO pump and circuit, 8 (57% perceived an improvement in their communication skills and 7 (50% perceived an improvement in their leadership skills. At the end of the course, 13 (93% delegates agreed that they felt more confident in dealing with ECMO. Conclusions: Simulation-training courses may increase knowledge and confidence in dealing with ECMO emergencies. Further studies are indicated to determine whether simulation training improves clinical outcomes and translates to reduced complication rates in patients receiving ECMO.

    Complex laparoscopic tasks require collaboration of surgeons as a surgical team. Conventionally, surgical teams are formed shortly before the start of the surgery, and team skills are built during the surgery. There is a need to establish a training simulation to improve surgical team skills without jeopardizing the safety of surgery. The Legacy Inanimate System for Laparoscopic Team Training (LISETT) is a bench simulation designed to enhance surgical team skills. The reported project tested the construct validity of LISETT. The research question was whether the LISETT scores show progressive improvement correlating with the level of surgical training and laparoscopic team experience or not. With LISETT, two surgeons are required to work closely to perform two laparoscopic tasks: peg transportation and suturing. A total of 44 surgical dyad teams were recruited, composed of medical students, residents, laparoscopic fellows, and experienced surgeons. The LISETT scores were calculated according to the speed and accuracy of the movements. The LISETT scores were positively correlated with surgical experience, and the results can be generalized confidently to surgical teams (Pearson's coefficient, 0.73; p = 0.001). To analyze the influences of individual skill and team dynamics on LISETT performance, team quality was rated by team members using communication and cooperation characters after each practice. The LISETT scores are positively correlated with self-rated team quality scores (Pearson's coefficient, 0.39; p = 0.008). The findings proved LISETT to be a valid system for assessing cooperative skills of a surgical team. By increasing practice time, LISETT provides an opportunity to build surgical team skills, which include effective communication and cooperation.

    Training simulators provide a real world environment for testing advanced diagnostic and control systems as an aid to nuclear power plant operators. The simulators not only duplicate the hardware din the actual control room, allowing for analysis of man-machine interface, but also represent the dynamic behavior of the reference plant in real-time, in a realistic manner. Training simulators provide the means to representing the reference plant operations in a wide range of operation conditions including off-normal and emergency conditions. Transient events with very low probability of occurrence can then be represented and used to test the capabilities of advanced diagnostic and control systems. For these reasons, full-scope operator training simulators have been used as a test bed for a number of advanced diagnostic concepts. The University of Michigan and Consumers Power Company have been collaborating in a program devoted to the development and study of advanced concepts for automatic diagnostics and control of nuclear power plants. The program has been focused on the use of the full-scope operator training Midland Nuclear Power Plant Unit 2 (MNP-2) Simulator for development, testing, and verification of advanced diagnostics concepts. In their current efforts, the authors have developed two artificial intelligent (AI) diagnostic concepts that have been applied to the MNP-2 Simulator: the systematic generation and updating of a rule-based knowledge system for nuclear power plant diagnostics and a nonlinear parameter estimation algorithm called the simulation filter. The simulation filter algorithm is used with the MNP-2 Simulator to improve the simulation of the Three Mile Island Unit 2 (TMI-2) accident. 11 refs., 4 figs

    Full Text Available Sanjay Konakondla, Reginald Fong, Clemens M Schirmer Department of Neurosurgery and Neuroscience Institute, Geisinger Medical Center, Geisinger Health System, Danville, PA, USA Abstract: The current simulation technology used for neurosurgical training leaves much to be desired. Significant efforts are thoroughly exhausted in hopes of developing simulations that translate to give learners the “real-life” feel. Though a respectable goal, this may not be necessary as the application for simulation in neurosurgical training may be most useful in early learners. The ultimate uniformly agreeable endpoint of improved outcome and patient safety drives these investments. We explore the development, availability, educational taskforces, cost burdens and the simulation advancements in neurosurgical training. The technologies can be directed at achieving early resident milestones placed by the Accreditation Council for Graduate Medical Education. We discuss various aspects of neurosurgery disciplines with specific technologic advances of simulation software. An overview of the scholarly landscape of the recent publications in the realm of medical simulation and virtual reality pertaining to neurologic surgery is provided. We analyze concurrent concept overlap between PubMed headings and provide a graphical overview of the associations between these terms. Keywords: residency education, simulation, neurosurgery training, virtual reality, haptic feedback, task analysis, ACGME

    Sandia National Laboratories has developed a distributed, high fidelity simulation system for training and planning small team Operations. The system provides an immersive environment populated by virtual objects and humans capable of displaying complex behaviors. The work has focused on developing the behaviors required to carry out complex tasks and decision making under stress. Central to this work are techniques for creating behaviors for virtual humans and for dynamically assigning behaviors to CGF to allow scenarios without fixed outcomes. Two prototype systems have been developed that illustrate these capabilities: MediSim, a trainer for battlefield medics and VRaptor, a system for planning, rehearsing and training assault operations.

    There is growing concern that medical students are inadequately prepared for life as a junior doctor. A lack of confidence managing acutely unwell patients is often cited as a barrier to good clinical care. With medical schools investing heavily in simulation equipment, we set out to explore if near-peer simulation training is an effective teaching format. Medical students in their third year of study and above were invited to attend a 90-minute simulation teaching session. The sessions were designed and delivered by final-year medical students using clinical scenarios mapped to the Sheffield MBChB curriculum. Candidates were required to assess, investigate and manage an acutely unwell simulated patient. Pre- and post-simulation training Likert scale questionnaires were completed relating to self-reported confidence levels. There is growing concern that medical students are inadequately prepared for life as a junior doctor RESULTS: Questionnaires were completed by 25 students (100% response rate); 52 per cent of students had no prior simulation experience. There were statistically significant improvements in self-reported confidence levels in each of the six areas assessed (p training benefits both teacher and learner and that this simplistic model could easily be replicated at other medical schools. As the most junior members of the team, medical students are often confined to observer status. Simulation empowers students to practise independently in a safe and protected environment. Furthermore, it may help to alleviate anxiety about starting work as a junior doctor and improve future patient care. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

    The current system of surgical education is facing many challenges in terms of time efficiency, costs, and patient safety. Training using simulation is an emerging area, mostly based on the experience of other high-risk professions like aviation. The goal of simulation-based training in surgery is to develop not only technical but team skills. This learning environment is stress-free and safe, allows standardization and tailoring of training, and also objectively evaluate performances. The development of simulation training is straightforward in endourology, since these procedures are video-assisted and the low degree of freedom of the instruments is easily replicated. On the other hand, these interventions necessitate a long learning curve, training in the operative room is especially costly and risky. Many models are already in use or under development in all fields of video-assisted urologic surgery: ureteroscopy, percutaneous surgery, transurethral resection of the prostate, and laparoscopy. Although bench models are essential, simulation increasingly benefits from the achievements and development of computer technology. Still in its infancy, virtual reality simulation will certainly belong to tomorrow's teaching tools.

    Simulation for perfusion education has been used for at least the past 25 years. The earlier models were either electronic (computer games) or fluid dynamic models and provided invaluable adjuncts to perfusion training and education. In 2009, the *North Shore-LIJ Health System at Great Neck, New York, opened an innovative "Bioskill Center" dedicated to simulated virtual reality advanced hands-on surgical training as well as perfusion simulation. Professional cardiac surgical organizations now show great interest in using simulation for training and recertification. Simulation will continue to be the direction for future perfusion training and education. This manuscript introduces a cost-effective system developed from discarded perfusion products and it is not intended to detail the actual lengthy process of its construction.

    1975-01-01

    A description is given of a training simulator for the full-scope real-time dynamic operation of a nuclear power plant which utilizes apparatus that includes control consoles having manual and automatic devices corresponding to simulated plant components and indicating devices for monitoring physical values in the simulated plants. A digital computer configuration is connected to the control consoles to calculate the dynamic real-time simulated operation of the plant in accordance with the simulated plant components to provide output data including data for operating the control console indicating devices. The plant simulation is modularized into various plant components or component systems. Simulated plant components or component systems are described by a mathematical equation embodied in a computer program which accepts data from other simulated plant components or systems, calculates output values including values which are used as inputs for simulator calculators by other simulated plant components or systems, and responds in a manner similar to that of its corresponding physical entity in both transient and steady states

    The knowledge gained from echocardiography is paramount for the clinician in diagnosing, interpreting, and treating various forms of disease. While cardiologists traditionally have undergone training in this imaging modality during their fellowship, many other specialties are beginning to show interest as well, including intensive care, anesthesia, and primary care trainees, in both transesophageal and transthoracic echocardiography. Advances in technology have led to the development of simulation programs accessible to trainees to help gain proficiency in the nuances of obtaining quality images, in a low stress, pressure free environment, often with a functioning ultrasound probe and mannequin that can mimic many of the pathologies seen in living patients. Although there are various training simulation programs each with their own benefits and drawbacks, it is clear that these programs are a powerful tool in educating the trainee and likely will lead to improved patient outcomes. © 2016, Wiley Periodicals, Inc.

  16. BEYOND INTEGRATED SYSTEM VALIDATION: USE OF A CONTROL ROOM TRAINING SIMULATOR FOR PROOF-OF-CONCEPT INTERFACE DEVELOPMENT

    Energy Technology Data Exchange (ETDEWEB)

    Ronald Boring; Vivek Agarwal

    2012-07-01

    This paper provides background on a reconfigurable control room simulator for nuclear power plants. The main control rooms in current nuclear power plants feature analog technology that is growing obsolete. The need to upgrade control rooms serves the practical need of maintainability as well as the opportunity to implement newer digital technologies with added functionality. There currently exists no dedicated research simulator for use in human factors design and evaluation activities for nuclear power plants in the US. The new research simulator discussed in this paper provides a test bed in which operator performance on new control room concepts can be benchmarked against existing control rooms and in which new technologies can be validated for safety and usability prior to deployment.

    This work describes a training simulator of Research Reactors (RR). The simulator is an interactive tool for teaching and operator training of the bases of the RR operation, reactor physics and thermal hydraulics. The Brazilian IEA-R1 RR was taken as the reference (default configuration). The implementation of the simulator consists of the modeling of the process and system (neutronics, thermal hydraulics), its numerical solution, and the implementation of the man-machine interface through visual interactive screens. The point kinetics model was used for the nuclear process and the heat and mass conservation models were used for the thermal hydraulic feed back in the average core channel. The heat exchanger and cooling tower were also modeled. The main systems were: the reactivity control system, including the automatic control, and the primary and secondary coolant systems. The Visual C++ was used to codes and graphics lay-outs. The simulator is to be used in a PC with Windows XP system. The simulator allows simulation in real time of start up, power maneuver, and shut down. (authors)

    This study examines the development and implementation of a pilot human factors curriculum during a 2-year period. It is one component of a comprehensive 5-year human factors curriculum spanning core competencies of interpersonal and communication skills, systems-based practice, and professionalism and using low-and high-fidelity simulation techniques. Members of the Department of Surgery and the Center for Clinical Communication and Performance Outcomes jointly constructed a curriculum for PGY1 and PGY2 residents on topics ranging from challenging communication to time and stress management. Video demonstrations, triggers, and simulated scenarios involving acting patients were created by surgeons and medical educators. Pre- and postintervention measures were obtained for communication skills, perceived stress level, and teamwork. Communication skills were evaluated using a series of video vignettes. The validated Perceived Stress Scale and Teamwork and Patient Safety Attitudes survey were used. Residents' perceptions of the program were also measured. Twenty-seven PGY1 residents and 15 PGY2 residents participated during 2 years. Analyses of video vignette tests indicated significant improvement in empathic communication for PGY1 (t = 3.62, p = 0.001) and PGY2 (t = 5.00, p = 0.004). There were no significant changes to teamwork attitudes. Perceived levels of stress became considerably higher. PGY1 residents reported trying 1 to 3 strategies taught in the time management session, with 60% to 75% reporting improvement post-training. This unique and comprehensive human factors curriculum is shown to be effective in building communication competency for junior-level residents in the human and emotional aspects of surgical training and practice. Continued refinement and ongoing data acquisition and analyses are underway. Copyright 2010 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

    1997-01-01

    Nuclear power plant simulators provide a vital tool in the training of operational staff in the statutory procedures and operational requirements of the nuclear industry. Scottish Nuclear, and its predecessor the South of Scotland Electricity Board, recognised the value such facilities offered to safety and efficiency and commissioned the construction of the Hunterston Operator Training Simulator as early as 1980. The simulator is a full scope, total plant, and real time system, with a complete 'as plant' replication of the operator interface, together with extensive instructor and tutorial facilities. Its uses have extended beyond the operator training role into plant engineering post incident analysis, evolving to be an essential feature of the station as a whole. Operation of the simulator for the foreseeable life of the station was the main driving force behind the current simulator update project, and whilst the need to move to a new computing platform, avoiding impending obsolescence problems, was the prime reason, the retention of 17 years of software development was seen as a valuable legacy to preserve. This paper discusses the main criteria considered during the simulator upgrade programme, highlighting the main technical issues and risks involved. (author)

    In this article, we present an Interventional Cardiology Training System developed by the Medical Application Group at Mitsubishi Electric in collaboration with the Center for Innovative Minimally Invasive Therapy. The core of the ICTS is a computer simulation of interventional cardiology catheterization. This simulation integrates clinical expertise, research in learning, and technical innovations to create a realistic simulated environment. The goal of this training system is to augment the training of new cardiology fellows as well as to introduce cardiologists to new devices and procedures. To achieve this goal, both the technical components and the educational content of the ICTS bring new and unique features: a simulated fluoroscope, a physics model of a catheter, a haptic interface, a fluid flow simulation combined with a hemodynamic model and a learning system integrated in a user interface. The simulator is currently able to generate--in real-time--high quality x-ray images from a 3D anatomical model of the thorax, including a beating heart and animated lungs. The heart and lung motion is controlled by the hemodynamic model, which also computes blood pressure and EKG. The blood flow is then calculated according to the blood pressure and blood vessel characteristics. Any vascular tool, such as a catheter, guide wire or angioplasty balloon can be represented and accurately deformed by the flexible tool physics model. The haptics device controls the tool and provides appropriate feedback when contact with a vessel wall is detected. When the catheter is in place, a contrast agent can be injected into the coronary arteries; blood and contrast mixing is computed and a visual representation of the angiogram is displayed by the x-ray renderer. By bringing key advances in the area of medical simulation--with the real-time x-ray renderer for instance--and by integrating in a single system both high quality simulation and learning tools, the ICTS opens new

    Lakey, S.R.A.; Gibbs, D.C.C.; Marchant, C.P.

    1980-01-01

    The Royal Naval College has devised a number of computer aided learning programmes applicable to health physics which include radiation shield design and optimisation, environmental impact of a reactor accident, exposure levels produced by an inert radioactive gas cloud, and the prediction of radiation detector response in various radiation field conditions. Analogue computers are used on reduced or fast time scales because time dependent phenomenon are not always easily assimilated in real time. The build-up and decay of fission products, the dynamics of intake of radioactive material and reactor accident dynamics can be effectively simulated. It is essential to relate these simulations to real time and the College applies a research reactor and analytical phantom to this end. A special feature of the reactor is a chamber which can be supplied with Argon-41 from reactor exhaust gases to create a realistic gaseous contamination environment. Reactor accident situations are also taught by using role playing sequences carried out in real time in the emergency facilities associated with the research reactor. These facilities are outlined and the training technique illustrated with examples of the calculations and simulations. The training needs of the future are discussed, with emphasis on optimisation and cost-benefit analysis. (H.K.)

    In recent years there has been a greater demand placed on the capabilities and time usage of real-time nuclear plant simulators due to NRC, INPO and utilities requirements. The requirements applied to certification, new simulators, upgrades, modifications, and maintenance of the simulators vary; however, they all require the capabilities of the simulator to be tested whether it is for NRC 10CFR55.45b requirements, ATP testing of new simulators, ATP testing of upgrades with or without panels, adding software/hardware due to plant modifications, or analyzing software/hardware problems on the simulator. This paper describes the Simulator Testing System (STS) which addresses each one of these requirements placed on simulators. Special attention will be given to ATP testing of upgrades without the use of control room panels. The capabilities and applications of the four parts of STS which are the Display Control Software (DCS), Procedure Control Software (PCS), Display Generator Software (DGS) and the Procedure Generator Software (PGS) will be reviewed

    Simulation is a common adjunct to operative training and various modalities exist for ureteroscopy. This systematic review aims the following: (1) to identify available ureteroscopy simulators, (2) to explore evidence for their effectiveness using characteristic criterion, and (3) to provide recommendations for simulation-based ureteroscopy training. The preferred reporting items for systematic reviews and meta-analysis statement guidelines were used. A literature search was performed using the PubMed, EMBASE, and Cochrane Library databases. In total, 20 articles concerning ureteroscopy simulators were included. Overall, 3 high-fidelity bench models are available. The Uro-Scopic Trainer has demonstrated face, construct, and concurrent validity, whereas the Scope Trainer has undergone content, construct, and predictive validation. The adult ureteroscopy trainer has demonstrated face, content, and construct validity. The URO Mentor is the only available ureteroscopy virtual-reality system; 10 studies were identified demonstrating its face, content, construct, concurrent, and predictive validity. The Uro-Scopic Trainer, the Scope Trainer, and the URO Mentor have demonstrated high educational impact. A noncommercially available, low-fidelity model has demonstrated effectiveness comparable to its high-fidelity counterpart at 185 times lesser than the price of the Uro-Scopic Trainer. The use of porcine models has also been described in 3 studies but require further study. Valid models are available for simulation-based ureteroscopy training. However, there is a lack of many high-level studies conducted, and further investigation is required in this area. Furthermore, current research focuses on the technical skills acquisition with little research conducted on nontechnical skills acquisition within ureteroscopy. The next step for ureteroscopy training is a formalized and validated curriculum, incorporating simulation, training models, development of nontechnical skills

    2015-07-01

    Ultrasound (US) imaging offers advantages over other imaging modalities and has become the most widespread modality for many diagnostic and interventional procedures. However, traditional 2D US requires a long training period, especially to learn how to manipulate the probe. A hybrid interactive system based on mixed reality was designed, implemented and tested for hand-eye coordination training in diagnostic and interventional US. A hybrid simulator was developed integrating a physical US phantom and a software application with a 3D virtual scene. In this scene, a 3D model of the probe with its relative scan plane is coherently displayed with a 3D representation of the phantom internal structures. An evaluation study of the diagnostic module was performed by recruiting thirty-six novices and four experts. The performances of the hybrid (HG) versus physical (PG) simulator were compared. After the training session, each novice was required to visualize a particular target structure. The four experts completed a 5-point Likert scale questionnaire. Seventy-eight percentage of the HG novices successfully visualized the target structure, whereas only 45% of the PG reached this goal. The mean scores from the questionnaires were 5.00 for usefulness, 4.25 for ease of use, 4.75 for 3D perception, and 3.25 for phantom realism. The hybrid US training simulator provides ease of use and is effective as a hand-eye coordination teaching tool. Mixed reality can improve US probe manipulation training.

    The voltage transformer test is an important means to monitor its operating state. The accuracy and reliability of the test data is directly related to the test skill level of the operator. However, the risk of test instruments damage, equipment being tested damage and electric shock in operator is caused by improper operation when training the transformer test. In this paper, a simulation device of voltage transformer is set up, and a simulation model is built for the most common 500kV capacitor voltage transformer (CVT), the simulation model can realize several test items of CVT by combing with teaching guidance platform, simulation instrument, complete set of system software and auxiliary equipment in Changchun. Many successful applications show that the simulation device has good practical value and wide application prospect.

    This paper discusses the implementation of two advanced diagnostic concepts for nuclear power plant diagnostics, the systematic generation and updating of a rule-based system and the simulation filter, at the Midland Nuclear Power Plant Unit 2 Training Simulator. The authors use an entropy minimax pattern recognition algorithm for the systematic construction of the diagnostic rule base. By extracting information from a transient database constructed with the Midland Simulator, the algorithm searches for trends in plant parameters, forming patterns or rules that describe the behavior of the transients. The rules are updated in an incremental manner within the context of the entropy minimax algorithm. The simulation filter is a nonlinear parameter estimation algorithm based on the extended Kalman filter. The authors use the simulation filter to improve the results of crude simulation models by optimally estimating system states given a set of measurements and results from a nonlinear simulation program. The Midland Simulator results of the Three Mile Island accident are significantly improved with the use of the simulation filter

    Full Text Available Game-based simulators, sometimes referred to as “lightweight” simulators, have benefits such as flexible technology and economic feasibility. In this article, we extend the notion of a game-based simulator by introducing multiple screen view and physical interaction. These features are expected to enhance immersion and fidelity. By utilizing these concepts we have constructed a training simulator for breathing apparatus entry. Game hardware and software have been used to produce the application. More important, the application itself is deliberately designed to be a game. Indeed, one important design goal is to create an entertaining and motivating experience combined with learning goals in order to create a serious game. The system has been evaluated in cooperation with the Swedish Rescue Services Agency to see which architectural features contribute to perceived fidelity. The modes of visualization and interaction as well as level design contribute to the usefulness of the system.

    The construction of the only NPP in Hungary - the Paks NPP - started in 1975. The four units of VVER-440/213 were connected to the grid in 1982, 1984, 1986 and 1987. During the construction no simulator has been delivered with the power plant. Moreover, there were no state-of-art simulators in Central and Eastern Europe and in the former Soviet Union; not for the given type, not for civil use. The only simulator for the VVER-440 existing that time was made for the Loviisa NPP in Finland. This plant is not very similar to the Paks NPP; moreover, the pressure suppression system in the hermetical part of the primary circuit, the instrumentation and control systems, the main control room and the secondary circuit are completely different. Anyway, the training of Paks operators on this simulator was out of question - regardless the similarity problems. The design of the Paks NPP was made in the Soviet Union, therefore not too much design information was available in Hungary. During the creation of simulation models the authors had to rely mostly on common theory and measured performance. Besides the efforts to create a basic principle, full-scope replica and compact simulators there was a great need to use verified codes with more detailed models for better understanding the behavior and for evaluation of the safety. Thanks to these great efforts, the simulators were expanded to evaluate the performance of the trainees, for simulation of SBLOCA and LBLOCA events; the authors are checking and validating the operational procedures; soon they start the design of the functions of a new reactor protection system and they participate in international efforts to deliver training simulators to other VVER-440 power plants. The paper gives an overview of all these activities, referring to some key publications for each of them

    Virtual reality simulators provide basic skills training without supervision in a controlled environment, free of pressure of operating on patients. Skills obtained through virtual reality simulation training can be transferred on the operating room. However, relative evidence is limited with data available only for basic surgical skills and for laparoscopic cholecystectomy. No data exist on the effect of virtual reality simulation on performance on advanced surgical procedures. Evidence suggests that performance on virtual reality simulators reliably distinguishes experienced from novice surgeons Limited available data suggest that independent approach on virtual reality simulation training is not different from proctored approach. The effect of virtual reality simulators training on acquisition of basic surgical skills does not seem to be different from the effect the physical simulators. Limited data exist on the effect of virtual reality simulation training on the acquisition of visual spatial perception and stress coping skills. Undoubtedly, virtual reality simulation training provides an alternative means of improving performance in laparoscopic surgery. However, future research efforts should focus on the effect of virtual reality simulation on performance in the context of advanced surgical procedure, on standardization of training, on the possibility of synergistic effect of virtual reality simulation training combined with mental training, on personalized training.

    Virtual reality simulators are becoming increasingly popular in dental schools across the world. But to what extent do these systems reflect actual dental ability? Addressing this question of construct validity is a fundamental step that is necessary before these systems can be fully integrated into a dental school's curriculum. In this study, we examined the sensitivity of the Simodont (a haptic virtual reality dental simulator) to differences in dental training experience. Two hundred and eighty-nine participants, with 1 (n = 92), 3 (n = 79), 4 (n = 57) and 5 (n = 61) years of dental training, performed a series of tasks upon their first exposure to the simulator. We found statistically significant differences between novice (Year 1) and experienced dental trainees (operationalised as 3 or more years of training), but no differences between performance of experienced trainees with varying levels of experience. This work represents a crucial first step in understanding the value of haptic virtual reality simulators in dental education. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Simulation-based training is a promising way to train a carrier flight deck crew because of the complex and dangerous working environment. Quantitative evaluation of simulation-based training quality is vital to make simulation-based training practical for aircraft carrier marshalling. This paper develops a personal computer-based aircraft carrier marshalling simulation system and a cave automatic virtual environment (CAVE-based immersive environment. In order to compare the training effectiveness of simulation-based training and paper-based training, a learning cubic model is proposed and a contrast experiment is carried out as well. The experimental data is analyzed based on a simplified Kirkpatrick’s model. The results show that simulation-based training is better than paper-based training by 26.80% after three rounds of testing, which prove the effectiveness of simulation-based aircraft carrier marshalling training.

    The periodical inspection of nuclear power plants needs a lot of workforces with a high degree of technical skill for the maintenance of various sorts of machines. Therefore, a new type of maintenance training system is required, where trainees can get training safely, easily and effectively. In this study we developed a training simulation system for disassembling a check valve in virtual environment (VE). The features of this system are as follows: Firstly, the trainees can execute tasks even in wrong order, and can experience the resultant conditions. In order to realize this environment, we developed a new Petri-net model for representing the objects' states in VE. This Petri-net model has several original characteristics, which make it easier to manage the change of the objects' states. Furthermore, we made a support system for constructing the Petri-net model of machine-disassembling training, because the Petri-net model is apt to become of large size. The effectiveness of this support system is shown through the system development. Secondly, this system can perform appropriate tasks to be done next in VE whenever the trainee wants even after some mistakes have been made. The effectiveness of this function has also been confirmed by experiments. (author)

    2005-10-24

    An unfortunate accident occurred in Graniteville, South Carolina on 6 January, 2005 when a train carrying a variety of hazardous chemicals collided with a stationary train parked on a siding rail (spur). The Savannah River National Laboratory (SRNL) runs prognostic atmospheric simulations of the Central Savannah River Area (CSRA) on an operational basis in the event of such airborne releases. Although forecast information was provided at 2-km horizontal grid spacing during the accident response, a higher-resolution simulation was later performed to examine influences of local topography on plume migration. The Regional Atmospheric Modeling System (RAMS, version 4.3.0) was used to simulate meteorology using multiple grids with an innermost grid spacing of 125 meters. This report discusses comparisons of simulated meteorology with local observations and applications using two separate transport models. Results from the simulations are shown to generally agree with meteorological observations at the time. Use of a dense gas model to simulate localized effects indicates agreement with fatalities in the immediate area and visible damage to vegetation.

    The fundamentals of endoscopic surgery (FES) program has considerable validity evidence for its use in measuring the knowledge, skills, and abilities required for competency in endoscopy. Beginning in 2018, the American Board of Surgery will require all candidates to have taken and passed the written and performance exams in the FES program. Recent work has shown that the current ACGME/ABS required case volume may not be enough to ensure trainees pass the FES skills exam. The aim of this study was to investigate the feasibility of a simulation-based mastery-learning curriculum delivered on a novel physical simulation platform to prepare trainees to pass the FES manual skills exam. The newly developed endoscopy training system (ETS) was used as the training platform. Seventeen PGY 1 (10) and PGY 2 (7) general surgery residents completed a pre-training assessment consisting of all 5 FES tasks on the GI Mentor II. Subjects then trained to previously determined expert performance benchmarks on each of 5 ETS tasks. Once training benchmarks were reached for all tasks, a post-training assessment was performed with all 5 FES tasks. Two subjects were lost to follow-up and never returned for training or post-training assessment. One additional subject failed to complete any portion of the curriculum, but did return for post-training assessment. The group had minimal endoscopy experience (median 0, range 0-67) and minimal prior simulation experience. Three trainees (17.6%) achieved a passing score on the pre-training FES assessment. Training consisted of an average of 48 ± 26 repetitions on the ETS platform distributed over 5.1 ± 2 training sessions. Seventy-one percent achieved proficiency on all 5 ETS tasks. There was dramatic improvement demonstrated on the mean post-training FES assessment when compared to pre-training (74.0 ± 8 vs. 50.4 ± 16, p learning curriculum using the ETS is feasible for training novices and allows for the acquisition of the technical

    In the ALICE experiment hundreds of users are analyzing big datasets on a Grid system. High throughput and short turn-around times are achieved by a centralized system called the LEGO trains. This system combines analysis from different users in so-called analysis trains which are then executed within the same Grid jobs thereby reducing the number of times the data needs to be read from the storage systems. The centralized trains improve the performance, the usability for users and the bookkeeping in comparison to single user analysis. The train system builds upon the already existing ALICE tools, i.e. the analysis framework as well as the Grid submission and monitoring infrastructure. The entry point to the train system is a web interface which is used to configure the analysis and the desired datasets as well as to test and submit the train. Several measures have been implemented to reduce the time a train needs to finish and to increase the CPU efficiency.

    The paper describes the German simulator scene. The simulator training is mainly being performed in a centre. The simulators used are nothing but fullscope simulators and were specified and built in accordance to a common design requirements philosophy. The simulators also support theoretical training by means of data processing devices in the classrooms, being connected to the simulators. As the quality of simulator training depends at least as much upon the instructors qualification as upon the simulators, the centre makes every effort to qualify and train their instructors including a final license and the obligation for maintaining competence. All simulator courses are prepared individually according to a common quality standard. The outcome of the course preparation are training materials for the instructors, the trainees and as well for the assessing course observers. The used assessment system is based on an observation of the trainees. Instructors and plant representatives evaluate the trainees performance against a detailed set of predefined training goals. It is the Simulator Centre's continuous effort to optimize all elements of simulator training, the simulators, the instructors and the didactical methods. (author)

    Simulators are widely used in occupations where practice in authentic environments would involve high human or economic risks. Surgical procedures can be simulated by increasingly complex and expensive techniques. This review gives an update on computer-based virtual reality (VR) simulators in training for laparoscopic cholecystectomies. From leading databases (Medline, Cochrane, Embase), randomised or controlled trials and the latest systematic reviews were systematically searched and reviewed. Twelve randomised trials involving simulators were identified and analysed, as well as four controlled studies. Furthermore, seven studies comparing black boxes and simulators were included. The results indicated any kind of simulator training (black box, VR) to be beneficial at novice level. After VR training, novice surgeons seemed to be able to perform their first live cholecystectomies with fewer errors, and in one trial the positive effect remained during the first ten cholecystectomies. No clinical follow-up data were found. Optimal learning requires skills training to be conducted as part of a systematic training program. No data on the cost-benefit of simulators were found, the price of a VR simulator begins at EUR 60 000. Theoretical background to learning and limited research data support the use of simulators in the early phases of surgical training. The cost of buying and using simulators is justified if the risk of injuries and complications to patients can be reduced. Developing surgical skills requires repeated training. In order to achieve optimal learning a validated training program is needed.

    The University of Minnesota: Simulations, Exercises and Effective Education: Preparedness and Emergency Response Learning Center uses simulations, which allow trainees to participate in realistic scenarios, to develop and evaluate competency. In a previous study, participants in Disaster in Franklin County: A Public Health Simulation demonstrated that prior bioterrorism and emergency readiness training (BT/ER) is significantly associated with better performance in a simulated emergency. We conducted a second analysis with a larger data set, remapping simulation questions to the Public Health Preparedness and Response Core Competency Model, Version 1.0. We performed an outcome evaluation of the impact of public health preparedness training. In particular, we compared individuals with significant BT/ER training to individuals without training on the basis of performance in a simulated emergency. We grouped participants as group 1 (≥45 hours of BT/ER training) and group 2 (gaming simulation, which was measured as the proportion of questions answered correctly for each participant. The relationship of effectiveness with significant BT/ER training was estimated using either multiple linear or logistic regression. For overall effectiveness, group 1 had 2% more correct decisions, on average, than group 2 (P gaming technology. Effectiveness differed by competency, indicating that more training may be needed in certain competency areas. Next steps to enhancing the usefulness of simulations in training should go beyond questioning if the learner learned and included questions related to the organizational factors that contributed to simulation effectiveness, and attributes of the simulation that encouraged competency and capacity building.

    For the operation management of nuclear power stations with high reliability and safety, the role played by operators is very important. The effort of improving the man-machine interface in the central control rooms of nuclear power stations is energetically advanced, but the importance of the role of operators does not change. For the training of the operators of nuclear power stations, simulators have been used from the early stage. As the simulator facilities for operator training, there are the full scope simulator simulating faithfully the central control room of an actual plant and the small simulator mainly aiming at learning the plant functions. For BWR nuclear power stations, two full scope simulators are installed in the BWR Operator Training Center, and the training has been carried out since 1974. The plant function learning simulators have been installed in respective electric power companies as the education and training facilities in the companies. The role of simulators in operator training, the BTC No.1 simulator of a BWR-4 of 780 MWe and the BTC No.2 simulator of a BWR-5 of 1,100 MWe, plant function learning simulators, and the design of the BTC No.2 simulator and plant function learning simulators are reported.

    To develop a robust psychomotor skills curriculum to teach pediatric airway foreign body retrieval and to assess the effect of this curriculum on residents' confidence in and ability to perform the complete task in an infant airway mannequin. Instructional course. Objective Structured Assessment of Technical Skills (OSATS). Surgical simulation laboratory. A half-day simulation-based course was developed to train otolaryngology residents in bronchoscopic foreign body retrieval. This complex psychomotor skill was deconstructed into subtasks. The following curricular learning objectives were presented and assessed: understanding of tracheobronchial anatomy, ability to adequately visualize the larynx with laryngoscopy, proficiency in rigid bronchoscopy, and familiarity with foreign body instrumentation. Residents were objectively evaluated on their ability to perform the complete task on a simulator before and after the course using an OSATS grading system. Confidence in successfully assembling the instruments and completing the task was assessed at these time periods. Seventeen otolaryngology residents completed the study. Confidence in assembling the instruments and in performing the complete task increased on average by 81% and 43%, respectively (P < .001). Using a 15-point OSATS grading system, the average score for the precourse was 7 and for the postcourse was 11.3 (P < .001). Simulation-based subtask training shows promise as an effective and reproducible method to teach the complex psychomotor task of airway foreign body retrieval. Completion of the curriculum led to a significant improvement in residents' confidence in and ability to perform bronchoscopic foreign body retrieval in an infant airway mannequin.

    In this research, UA is defined as an inappropriate human behavior that has a potential for leading the safety of NPPs to a negative direction. The purpose of this paper is to describe a process of UA analysis through a case study under a simulated emergency and the analysis results. In this paper, we described the process for UA identification and demonstrated examples of UA accompanied by consequence by a case study on ISLOCA scenario. It is well known that the contribution of human performance related problems (or human error) to the safety of sociotechnical systems is critical. Moreover, it is reported that about 75% of all accidents and/or incidents that have occurred in the complicated process control systems are attributable to human error. Therefore lots of efforts to perform an HRA (Human Reliability Analysis) based on various approaches made to enhance their safety. HRA data is an important prerequisite for improving HRA quality. For this reason, KAERI (Korea Atomic Energy Research Institute) developed a standardized guideline is to specify how to gather HRA data from simulator training records and crated IGT (Information Gathering Template) specifying what kinds of measures should be observed during the simulations. Based on the data collection framework, we have performed data collection to analyze inappropriate human behavior (or UA; Unsafe Act) with simulator training data about various scenario needed AOP (Abnormal Operation Procedure) or EOP (Emergency Operation Procedure) operations for HEP (Human Error Probability) calculation

  14. The development of a reactor training simulator at the ATR

    1989-01-01

    Since the accident at Three Mile Island, the need for effective reactor operator training has been widely recognized as a priority item. The US Nuclear Regulatory Commission rules now call for each plant to have a plant-specific simulator available for operator training by 1990. To be effective, the training simulators must provide more detail, respond more realistically, and allow more flexibility in training scenarios than do current simulators. To work toward this need, the US Department of Energy created the Idaho National Engineering Laboratory (INEL) Engineering Simulation Center in April 1988, charged with the creation of a modern, flexible, state-of-the-art simulation facility. One of the simulator projects currently being pursued by the Engineering Simulation Center is the development of a full-scope, high-fidelity reactor control room simulator at the Advanced Test Reactor (ATR)

    In a randomized controlled trial of arthroscopic training tools, the low-cost/low-fidelity Cigar Box Arthroscopy Trainer demonstrated equivalent efficacy to the validated, and more expensive, Anatomic Knee Arthroscopy Trainer (AKAT) in the training of novice arthroscopists using a validated scoring system, the Basic Arthroscopic Knee Skill Scoring System. As simulation training and formal surgical skills training is now mandatory, residency and fellowship programs are required to incorporate training modules and equipment to maximize learning while minimizing potential for patient harm. Low-cost, low-fidelity simulation tools such as this may provide a solution to do so while minimizing costs and maximizing educational returns on investment. The value in simulation training will be in its synergistic ability to augment the traditional apprenticeship model of resident and fellow training.

    2017-04-01

    The challenges of training and assessing endourologic skill have driven the development of new training systems. The Center for Research in Education and Simulation Technologies (CREST) has developed a team and a methodology to facilitate this development process. Backwards design principles were applied. A panel of experts first defined desired clinical and educational outcomes. Outcomes were subsequently linked to learning objectives. Gross task deconstruction was performed, and the primary domain was classified as primarily involving decision-making, psychomotor skill, or communication. A more detailed cognitive task analysis was performed to elicit and prioritize relevant anatomy/tissues, metrics, and errors. Reference anatomy was created using a digital anatomist and clinician working off of a clinical data set. Three dimensional printing can facilitate this process. When possible, synthetic or virtual tissue behavior and textures were recreated using data derived from human tissue. Embedded sensors/markers and/or computer-based systems were used to facilitate the collection of objective metrics. A learning Verification and validation occurred throughout the engineering development process. Nine endourology-relevant training systems were created by CREST with this approach. Systems include basic laparoscopic skills (BLUS), vesicourethral anastomosis, pyeloplasty, cystoscopic procedures, stent placement, rigid and flexible ureteroscopy, GreenLight PVP (GL Sim), Percutaneous access with C-arm (CAT), Nephrolithotomy (NLM), and a vascular injury model. Mixed modalities have been used, including "smart" physical models, virtual reality, augmented reality, and video. Substantial validity evidence for training and assessment has been collected on systems. An open source manikin-based modular platform is under development by CREST with the Department of Defense that will unify these and other commercial task trainers through the common physiology engine, learning

    Cochlear implantation is the standard of care for infants born with severe hearing loss. Current guidelines approve the surgical placement of implants as early as 12 months of age. Implantation at a younger age poses a greater surgical challenge since the underdeveloped mastoid tip, along with thin calvarial bone, creates less room for surgical navigation and can result in increased surgical risk. We have been developing a temporal bone dissection simulator based on actual clinical cases for training otolaryngology fellows in this delicate procedure. The simulator system is based on pre-procedure CT (Computed Tomography) images from pediatric infant cases (<12 months old) at our hospital. The simulator includes: (1) simulation engine to provide the virtual reality of the temporal bone surgery environment, (2) a newly developed haptic interface for holding the surgical drill, (3) an Oculus Rift to provide a microscopic-like view of the temporal bone surgery, and (4) user interface to interact with the simulator through the Oculus Rift and the haptic device. To evaluate the system, we have collected 10 representative CT data sets and segmented the key structures: cochlea, round window, facial nerve, and ossicles. The simulator will present these key structures to the user and warn the user if needed by continuously calculating the distances between the tip of surgical drill and the key structures.

  18. [Emergency medical training through simulation : Always the same for everyone?

    2017-03-01

    Simulation assumes a growing importance in the field of emergency medical education. Many rescue service schools work with simulators or even have their own simulation center. Classic resuscitation training in the classroom is increasingly being replaced by realistic case scenarios. But simulators themselves do not train! Using a simulator in emergency medical training does not necessarily mean achieving sustained learning success among the participants. Depending on the skills, abilities or competences being taught, there seems to be different requirements for simulation. However, there is no scientific evidence about how strong learners should be stressed in order to achieve the best learning effect. However, it can be stated that for training purely technical skills, simulators that represent the anatomical or physiological reality as accurately as possible should be used. If soft skills, practical knowledge and decision-making are the learning objectives, a scenario with extremly realistic conditions needs to be embedded. Mid-fidelity simulators seem to be able to cover the widest range of imparting skills for emergency medical training. No matter what simulator is used, the following applies: The selected scenario must be realistic and the simulation as well as technical capabilities of the simulator must be coordinated. A well-presented scenario with a well-trained teacher using a simple resuscitation doll appears to be better than a highly complex, however unrealistic, amateur simulation scenario for successful learning.

    The first three phases of Training System Development (TSD) -- job and task analysis, curriculum design, and training material development -- are time consuming and labor intensive. The use of personal computers with a combination of commercial and custom-designed software resulted in a significant reduction in the man-hours required to complete these phases for a Health Physics Technician Training Program at a nuclear power station. This paper reports that each step in the training program project involved the use of personal computers: job survey data were compiled with a statistical package, task analysis was performed with custom software designed to interface with a commercial database management program. Job Performance Measures (tests) were generated by a custom program from data in the task analysis database, and training materials were drafted, edited, and produced using commercial word processing software

    It is important to develop a training program by simulators in main control room of nuclear power plants because there is no an operation expert and no operating experience in the pre-construction phase of nuclear power plants. It is also necessary to develop a training program and its evaluation method taking human error into account. The purpose of this study is developing evaluation model of simulators. In a training program, once training requirements are selected, evaluation of training is as important as its implementation. Training effectiveness is available value in a simulator-based environment. The main control room of SMART (System-integrated Modular Advanced ReacTor) is consist of workstation, visual display units such as LDP and FPD based on digital systems. Cognitive behaviors of a high level are required to operators in these man-machine interface system (MMIS). Therefore, it is essential to identify training requirements and to develop its evaluation model. Virtual Environments such as a simulator have utilized by a lot of industries and companies for training and accident prevention. Simulators have three primary benefits. The first is that training by simulators is less expensive than those in real environment. The second is that simulators enable safety enhancement using systematic training program. The third is that simulators provide a preliminary to prevent human error. It is significant to apply TER, TCR, TCE in evaluation of training effect. It is expected that these could be applied to revise training criteria and enable to consider efficiency in terms of cost and benefit

    Billoen, G. van

    1994-01-01

    The training cycle of nuclear power plant (NPP) operators has evolved during the last decade in parallel with the evolution of the training tools. The phases of the training cycle can be summarized as follows: (1) basic principle learning, (2) specific functional training, (3) full operating range training, and (4) detailed accident analyses. The progress in simulation technology and man/machine interface (MMI) gives the training centers new opportunities to improve their training methods and effectiveness in the transfer of knowledge. To take advantage of these new opportunities a significant investment in simulation tools may be required. It is therefore important to propose an optimized approach when dealing with the overall equipment program for these training centers. An overall look of tools proposed on the international simulation market shows that there is a need for systematic approach in this field. Classification of the different training tools needed for each training cycle is the basis for an optimized approach in terms of hardware configuration and software specifications of the equipment to install in training centers. The 'Multi-Function Simulator' is one of the approaches. (orig.) (3 tabs.)

This simulator allows for engineers to train and further understand the dynamics of their system from their local desktops. It allows the users to train and evaluate their system at a pace and skill level based on the user's competency and from a perspective based on the user's need. The simulator will not require any special resources to execute and should generally be available for use. The interface is based on a concept of presenting the model of the system in ways that best suits the user's application or training needs. The three levels of views are Component View, the System View (overall system), and the Console View (monitor). These views are portals into a single model, so changing the model from one view or from a model manager Graphical User Interface will be reflected on all other views.

    Full Text Available The study described in this paper deals with the issue of a design tool for the autopilot of an Unmanned Aerial Vehicle (UAV and the selection of the airdata and inertial system sensors. This project was processed in cooperation with VTUL a PVO o.z. [1]. The feature that distinguishes the autopilot requirements of a UAV (Figs. 1, 7, 8 from the flight systems of conventional manned aircraft is the paradox of controlling a high bandwidth dynamical system using sensors that are in harmony with the low cost low weight objectives that UAV designs are often expected to achieve. The principal function of the autopilot is flight stability, which establishes the UAV as a stable airborne platform that can operate at a precisely defined height. The main sensor for providing this height information is a barometric altimeter. The solution to the UAV autopilot design was realised with simulations using the facilities of Matlab® and in particular Simulink®[2].

    Natural Orifice Transluminal Endoscopic Surgery (NOTES) provides an emerging surgical technique which usually needs a long learning curve for surgeons. Virtual reality (VR) medical simulators with vision and haptic feedback can usually offer an efficient and cost-effective alternative without risk to the traditional training approaches. Under this motivation, we developed the first virtual reality simulator for transvaginal cholecystectomy in NOTES (VTEST™). This VR-based surgical simulator aims to simulate the hybrid NOTES of cholecystectomy. We use a 6DOF haptic device and a tracking sensor to construct the core hardware component of simulator. For software, an innovative approach based on the inner-spheres is presented to deform the organs in real time. To handle the frequent collision between soft tissue and surgical instruments, an adaptive collision detection method based on GPU is designed and implemented. To give a realistic visual performance of gallbladder fat tissue removal by cautery hook, a multi-layer hexahedral model is presented to simulate the electric dissection of fat tissue. From the experimental results, trainees can operate in real time with high degree of stability and fidelity. A preliminary study was also performed to evaluate the realism and the usefulness of this hybrid NOTES simulator. This prototyped simulation system has been verified by surgeons through a pilot study. Some items of its visual performance and the utility were rated fairly high by the participants during testing. It exhibits the potential to improve the surgical skills of trainee and effectively shorten their learning curve. Copyright © 2016 Elsevier Inc. All rights reserved.

  2. Virtual reality simulation training of mastoidectomy - studies on novice performance.

    Andersen, Steven Arild Wuyts

    2016-08-01

    Virtual reality (VR) simulation-based training is increasingly used in surgical technical skills training including in temporal bone surgery. The potential of VR simulation in enabling high-quality surgical training is great and VR simulation allows high-stakes and complex procedures such as mastoidectomy to be trained repeatedly, independent of patients and surgical tutors, outside traditional learning environments such as the OR or the temporal bone lab, and with fewer of the constraints of traditional training. This thesis aims to increase the evidence-base of VR simulation training of mastoidectomy and, by studying the final-product performances of novices, investigates the transfer of skills to the current gold-standard training modality of cadaveric dissection, the effect of different practice conditions and simulator-integrated tutoring on performance and retention of skills, and the role of directed, self-regulated learning. Technical skills in mastoidectomy were transferable from the VR simulation environment to cadaveric dissection with significant improvement in performance after directed, self-regulated training in the VR temporal bone simulator. Distributed practice led to a better learning outcome and more consolidated skills than massed practice and also resulted in a more consistent performance after three months of non-practice. Simulator-integrated tutoring accelerated the initial learning curve but also caused over-reliance on tutoring, which resulted in a drop in performance when the simulator-integrated tutor-function was discontinued. The learning curves were highly individual but often plateaued early and at an inadequate level, which related to issues concerning both the procedure and the VR simulator, over-reliance on the tutor function and poor self-assessment skills. Future simulator-integrated automated assessment could potentially resolve some of these issues and provide trainees with both feedback during the procedure and immediate

    Virtual reality simulation training may improve knowledge of anatomy and surgical skills. We evaluated a 3-dimensional, haptic, virtual reality temporal bone simulator for dissection training. The subjects were 7 otolaryngology residents (3 training sessions each) and 7 medical students (1 training session each). The virtual reality temporal bone simulation station included a computer with software that was linked to a force-feedback hand stylus, and the system recorded performance and collisions with vital anatomic structures. Subjects performed virtual reality dissections and completed questionnaires after the training sessions. Residents and students had favorable responses to most questions of the technology acceptance model (TAM) questionnaire. The average TAM scores were above neutral for residents and medical students in all domains, and the average TAM score for residents was significantly higher for the usefulness domain and lower for the playful domain than students. The average satisfaction questionnaire for residents showed that residents had greater overall satisfaction with cadaver temporal bone dissection training than training with the virtual reality simulator or plastic temporal bone. For medical students, the average comprehension score was significantly increased from before to after training for all anatomic structures. Medical students had significantly more collisions with the dura than residents. The residents had similar mean performance scores after the first and third training sessions for all dissection procedures. The virtual reality temporal bone simulator provided satisfactory training for otolaryngology residents and medical students. Copyright © 2013. Published by Elsevier Ireland Ltd.

Little evidence exists to objectify best practice. We sought to evaluate live tissue and simulation-based training practices in 12 life-saving emergency procedures. In the study, 742 subjects were randomized to live tissue or simulation-training. Assessments of self-efficacy, cognitive knowledge, and psychomotor performance were completed pre- and post-training. Affective response to training was assessed through electrodermal activity. Subject matter experts gap analysis of live tissue versus simulation completed the data set. Subjects demonstrated pre- to post-training gains in self-efficacy, cognitive knowledge, psychomotor performance, and affective response regardless of training modality (P Affective response was greatest in live tissue training (P abandonment of live tissue training is not warranted. We maintain that combined live tissue and simulation-based training add value and should be continued. Congressional mandates may accelerate simulation development and improve performance.

    Full text: The paper aims at presenting the results of Cernavoda NPP Training Department modernization project. In order to achieve a training system of knowledge society in the first stage of the project a Computer Based Training (CBT) or E-Learning platform and several CBT objects/courses were worked out. The conceived E-Learning solution is called CBT Center and it is a complete system offering a variety of teaching and learning services to its users. CBT and/or E-Learning always mean two things: a software platform and content authoring. Ideally, a software platform should be able to import any type of flat documentation and integrate it into a structured database which keeps track of pedagogically meaningful information like the student's progress in studying materials, tests and quiz, marks, etc. At the same time, the materials, the study and the tests have to be organized around certain objectives which play the role of guidelines during the entire educational activity. An example of such a course which has been successfully integrated into CBT Center is the 'Thermodynamics'. CBT technology implementation at NPP Cernavoda Training Department has brought several advantages: the technology improves overall communication between all individuals which are part of the educational process; there is no space problem any more; students can access training materials from their own desk using the NPP intranet; the logistics problem will decrease, while more and more disciplines will be transformed as CBT objects.

    Attention Deficit Disorder (ADD) is a behavioral disorder characterized by the inability to sustain attention long enough to perform activities such as schoolwork or organized play. Treatments for this disorder include medication and brainwave biofeedback training. Brainwave biofeedback training systems feed back information to the trainee showing him how well he is producing the brainwave pattern that indicates attention. The Extended Attention Span Training (EAST) system takes the concept a step further by making a video game more difficult as the player's brainwaves indicate that attention is waning. The trainee can succeed at the game only by maintaining an adequate level of attention. The EAST system is a modification of a biocybernetic system that is currently being used to assess the extent to which automated flight management systems maintain pilot engagement. This biocybernetic system is a product of a program aimed at developing methods to evaluate automated flight deck designs for compatibility with human capabilities. The EAST technology can make a contribution in the fields of medical neuropsychology and neurology, where the emphasis is on cautious, conservative treatment of youngsters with attention disorders.

    An increasing number of reports indicate the efficacy of simulation training in anesthesiology resident education. Simulation education helps learners to acquire clinical skills in a safe learning environment without putting real patients at risk. This useful tool allows anesthesiology residents to obtain medical knowledge and both technical and non-technical skills. For faculty members, simulation-based settings provide the valuable opportunity to evaluate residents' performance in scenarios including airway management and regional, cardiac, and obstetric anesthesiology. However, it is still unclear what types of simulators should be used or how to incorporate simulation education effectively into education curriculums. Whether simulation training improves patient outcomes has not been fully determined. The goal of this review is to provide an overview of the status of simulation in anesthesiology resident education, encourage more anesthesiologists to get involved in simulation education to propagate its influence, and stimulate future research directed toward improving resident education and patient outcomes.

    Traditionally, training in gastrointestinal endoscopy has been based upon an apprenticeship model, with novice endoscopists learning basic skills under the supervision of experienced preceptors in the clinical setting. Over the last two decades, however, the growing awareness of the need for patient safety has brought the issue of simulation-based training to the forefront. While the use of simulation-based training may have important educational and societal advantages, the effectiveness of virtual reality gastrointestinal endoscopy simulators has yet to be clearly demonstrated. To determine whether virtual reality simulation training can supplement and/or replace early conventional endoscopy training (apprenticeship model) in diagnostic oesophagogastroduodenoscopy, colonoscopy and/or sigmoidoscopy for health professions trainees with limited or no prior endoscopic experience. Health professions, educational and computer databases were searched until November 2011 including The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, Scopus, Web of Science, Biosis Previews, CINAHL, Allied and Complementary Medicine Database, ERIC, Education Full Text, CBCA Education, Career and Technical Education @ Scholars Portal, Education Abstracts @ Scholars Portal, Expanded Academic ASAP @ Scholars Portal, ACM Digital Library, IEEE Xplore, Abstracts in New Technologies and Engineering and Computer & Information Systems Abstracts. The grey literature until November 2011 was also searched. Randomised and quasi-randomised clinical trials comparing virtual reality endoscopy (oesophagogastroduodenoscopy, colonoscopy and sigmoidoscopy) simulation training versus any other method of endoscopy training including conventional patient-based training, in-job training, training using another form of endoscopy simulation (e.g. low-fidelity simulator), or no training (however defined by authors) were included.  Trials comparing one method of virtual reality training versus

    Modern simulation techniques have a growing role for evaluating new technologies and for developing cost-effective training programs. A mission simulator facilitates the productive exchange of ideas by demonstration of concepts through compellingly realistic computer simulation. Revolutionary advances in 3D simulation technology have made it possible for desktop computers to process strikingly realistic and complex interactions with results depicted in real-time. Computer games now allow for multiple real human players and "artificially intelligent" (AI) simulated robots to play together. Advances in computer processing power have compensated for the inherent intensive calculations required for complex simulation scenarios. The main components of the leading game-engines have been released for user modifications, enabling game enthusiasts and amateur programmers to advance the state-of-the-art in AI and computer simulation technologies. It is now possible to simulate sophisticated and realistic conflict situations in order to evaluate the impact of non-lethal devices as well as conflict resolution procedures using such devices. Simulations can reduce training costs as end users: learn what a device does and doesn't do prior to use, understand responses to the device prior to deployment, determine if the device is appropriate for their situational responses, and train with new devices and techniques before purchasing hardware. This paper will present the status of SARA's mission simulation development activities, based on the Half-Life gameengine, for the purpose of evaluating the latest non-lethal weapon devices, and for developing training tools for such devices.

    1985-01-01

    In this paper the role of instructional psychology in simulator design and use is discussed. It is suggested that research and development work has tended to focus upon the face validity of simulators rather than their instructional utility. Dimensions of simulation are reviewed as are the variety of uses to which a simulator may be put. The nature of instructional psychology is briefly described under the following headings: task analysis, the acquisition of knowledge and skill and theories of instruction. Attention is also given to the potential role of computer-based training and the topic of retention of training is introduced. (author)

    The Virtual Electrosurgical Skill Trainer is a tool for training surgeons the safe operation of electrosurgery tools in both open and minimally invasive surgery. This training includes a dedicated team-training module that focuses on operating room (OR) fire prevention and response. The module was developed to allow trainees, practicing surgeons, anesthesiologist, and nurses to interact with a virtual OR environment, which includes anesthesia apparatus, electrosurgical equipment, a virtual patient, and a fire extinguisher. Wearing a head-mounted display, participants must correctly identify the "fire triangle" elements and then successfully contain an OR fire. Within these virtual reality scenarios, trainees learn to react appropriately to the simulated emergency. A study targeted at establishing the face validity of the virtual OR fire simulator was undertaken at the 2015 Society of American Gastrointestinal and Endoscopic Surgeons conference. Forty-nine subjects with varying experience participated in this Institutional Review Board-approved study. The subjects were asked to complete the OR fire training/prevention sequence in the VEST simulator. Subjects were then asked to answer a subjective preference questionnaire consisting of sixteen questions, focused on the usefulness and fidelity of the simulator. On a 5-point scale, 12 of 13 questions were rated at a mean of 3 or greater (92%). Five questions were rated above 4 (38%), particularly those focusing on the simulator effectiveness and its usefulness in OR fire safety training. A total of 33 of the 49 participants (67%) chose the virtual OR fire trainer over the traditional training methods such as a textbook or an animal model. Training for OR fire emergencies in fully immersive VR environments, such as the VEST trainer, may be the ideal training modality. The face validity of the OR fire training module of the VEST simulator was successfully established on many aspects of the simulation.

    Laparoscopy has been widely used to perform abdominal surgeries, as it is advantageous in that the patients experience lower post-surgical trauma, shorter convalescence, and less pain as compared to traditional surgery. Laparoscopic surgeries require precision; therefore, it is imperative to train surgeons to reduce the risk of operation. Laparoscopic simulators offer a highly realistic surgical environment by using virtual reality technology, and it can improve the training efficiency of laparoscopic surgery. This paper presents a virtual Laparoscopic surgery system. The proposed system utilizes the Visible Chinese Human (VCH) to construct the virtual models and simulates real-time deformation with both improved special mass-spring model and morph target animation. Meanwhile, an external device that integrates two five-degrees-of-freedom (5-DOF) manipulators was designed and made to interact with the virtual system. In addition, the proposed system provides a modular tool based on Unity3D to define the functions and features of instruments and organs, which could help users to build surgical training scenarios quickly. The proposed virtual laparoscopic training system offers two kinds of training mode, skills training and surgery training. In the skills training mode, the surgeons are mainly trained for basic operations, such as laparoscopic camera, needle, grasp, electric coagulation, and suturing. In the surgery-training mode, the surgeons can practice cholecystectomy and removal of hepatic cysts by guided or non-guided teaching.

    2017-11-01

    Today's educational environment has made it more difficult to rely on the Halstedian model of "see one, do one, teach one" in gynecologic surgical training. There is decreased surgical volume, but an increased number of surgical modalities. Fortunately, surgical simulation has evolved to fill the educational void. Whether it is through skill generalization or skill transfer, surgical simulation has shifted learning from the operating room back to the classroom. This article explores the principles of surgical education and ways to introduce simulation as an adjunct to residency training. We review high- and low-fidelity surgical simulators, discuss the progression of surgical skills, and provide options for skills competency assessment. Time and money are major hurdles when designing a simulation curriculum, but low-fidelity models, intradepartmental cost sharing, and utilizing local experts for simulation proctoring can aid in developing a simulation program.

    Ultrasound-guided regional anesthesia (UGRA) has become the criterion standard of regional anesthesia practice. Ultrasound-guided regional anesthesia teaching programs often use simulation, and guidelines have been published to help guide URGA education. This systematic review aimed to examine the effectiveness of simulation-based education for the acquisition and maintenance of competence in UGRA. Studies identified in MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, and ERIC were included if they assessed simulation-based UGRA teaching with outcomes measured at Kirkpatrick level 2 (knowledge and skills), 3 (transfer of learning to the workplace), or 4 (patient outcomes). Two authors independently reviewed all identified references for eligibility, abstracted data, and appraised quality. After screening 176 citations and 45 full-text articles, 12 studies were included. Simulation-enhanced training improved knowledge acquisition (Kirkpatrick level 2) when compared with nonsimulation training. Seven studies measuring skill acquisition (Kirkpatrick level 2) found that simulation-enhanced UGRA training was significantly more effective than alternative teaching methods or no intervention. One study measuring transfer of learning into the clinical setting (Kirkpatrick level 3) found no difference between simulation-enhanced UGRA training and non-simulation-based training. However, this study was discontinued early because of technical challenges. Two studies examined patient outcomes (Kirkpatrick level 4), and one of these found that simulation-based UGRA training improved patient outcomes compared with didactic teaching. Ultrasound-guided regional anesthesia knowledge and skills significantly improved with simulation training. The acquired UGRA skills may be transferred to the clinical setting; however, further studies are required to confirm these changes translate to improved patient outcomes.

    The paper describes a continuation of efforts of an international Russian - Norwegian joint team to improve operational safety during the refuelling process of an RBMK-type reactor by implementing a training simulator based on an innovative Virtual Reality (VR) approach. During the preceding 1st stage of the project a display-based simulator was extended with VR models of the real Refuelling Machine (RM) and its environment in order to improve both the learning process and operation's effectiveness. The simulator's challenge is to support the performance (operational activity) of RM operational staff firstly by helping them to develop basic knowledge and skills as well as to keep skilled staff in close touch with the complex machinery of the Refuelling Machine. During the 2nd stage of the joint project the functional scope of the VR-simulator was greatly enhanced - firstly, by connecting to the RBMK-unit full-scope simulator, and, secondly, by including a training program and simulator model upgrade. The present 3rd stage of the Project is primarily oriented towards the improvement of the training process for maintenance and operational personnel by means of a development of the Training Support Methodology and Courses (TSMC) to be based on Virtual Reality and enlarged functionality of 3D and process modelling. The TMSC development is based on Russian and International Regulatory Bodies requirements and recommendations. Design, development and creation of a specialised VR-based Training System for RM Maintenance Personnel are very important for the Russian RBMK plants. The main goal is to create a powerful, autonomous VR-based simulator for training technical maintenance personnel on the Refuelling Machine. VR based training is expected to improve the effect of training compared to the current training based on traditional methods using printed documentation. The LNPP management and the Regulatory Bodies supported this goal. The VR-based Training System should

    2012-11-01

    Simulation training has emerged as an effective way to complement clinical training of medical students. Yet outcomes from simulation training must be considered suboptimal when 25-30% of students fail to recognise a cardiac murmur on which they were trained 1 hour previously. There are several possible explanations for failure to improve following simulation training, which include the impact of heightened emotions on learning and cognitive overload caused by interactivity with high-fidelity simulators. This study was conducted to assess emotion during simulation training and to explore the relationships between emotion and cognitive load, and diagnostic performance. We trained 84 Year 1 medical students on a scenario of chest pain caused by symptomatic aortic stenosis. After training, students were asked to rate their emotional state and cognitive load. We then provided training on a dyspnoea scenario before asking participants to diagnose the murmur in which they had been trained (aortic stenosis) and a novel murmur (mitral regurgitation). We used factor analysis to identify the principal components of emotion, and then studied the associations between these components of emotion and cognitive load and diagnostic performance. We identified two principal components of emotion, which we felt represented invigoration and tranquillity. Both of these were associated with cognitive load with adjusted regression coefficients of 0.63 (95% confidence interval [CI] 0.28-0.99; p = 0.001) and - 0.44 (95% CI - 0.77 to - 0.10; p = 0.009), respectively. We found a significant negative association between cognitive load and the odds of subsequently identifying the trained murmur (odds ratio 0.27, 95% CI 0.11-0.67; p = 0.004). We found that increased invigoration and reduced tranquillity during simulation training were associated with increased cognitive load, and that the likelihood of correctly identifying a trained murmur declined with increasing cognitive load.

    In Japanese nuclear power stations, owing to the improvement of fuel management, thorough maintenance and inspection, and the improvement of facilities, high capacity ratio has been attained. The thorough training of operators in nuclear power stations also contributes to it sufficiently. The BWR operator training center was established in 1971, and started the training of operators in April, 1974. As of the end of March, 1986, more than 1800 trainees completed training. At present, in the BWR operator training center, No.1 simulator of 800 MW class and No.2 simulator of 1100 MW class are operated for training. In this report, the method, by newly adopting it, good result was obtained, is described, that is, the method of introducing the feeling of being present on the spot into the place of training, and the new testing method introduced in retraining course. In the simulator training which is apt to place emphasis on a central control room, the method of stimulating trainees by playing the part of correspondence on the spot and heightening the training effect of multiple monitoring was tried, and the result was confirmed. The test of confirmation on the control board was added. (Kako, I.)

    The Japan Atomic Energy Agency, at its Japan Materials Testing Reactor (JMTR), completed an irradiation test reactor simulator in May 2012. This simulator simulates the operation, irradiation test, abnormal transient change during operation, and accident progress events, etc., and is able to perform operation training on reactor and irradiation equipment corresponding to the above simulations. This simulator is composed of a reactor control panel, process control panel, irradiation equipment control panel, instructor control panel, large display panel, and compute server. The completed simulator has been utilized in the education and training of JMTR operators for the purpose of the safe and stable operation of JMTR and the achievement of high operation rate after resuming operation. For the education and training, an education and training curriculum has been prepared for use in not only operation procedures at the time of normal operation, but also learning of fast and accurate response in case of accident events. In addition, this simulator is also being used in operation training for the purpose of contributing to the cultivation of human resources for atomic power in and out of Japan. (A.O.)

  10. The current role of simulation in urological training.

    Preece, Ryan

    2015-01-01

    Simulation is becoming an increasingly popular educational tool in numerous surgical specialities, including urology. This article reviews the current role of urological simulators; discussing their need, availability, incorporation and current limitations. A literature review of the electronic databases Medline, Embase and Google Scholar was performed. For increasingly limited urological training programs, simulation can act as a valuable adjunct to clinical training. Evidence suggests that simulation enables the trainee to bypass the early, error-prone part of the surgical learning curve. It should be incorporated into proficiency-based curricula, with junior trainees initially beginning with low fidelity simulators to grasp basic surgical skills before moving onto full-procedural simulation as they progress through their training. A wide variety of simulators of differing fidelity are currently available, teaching both technical (eg. cystoscopy) and non-technical (eg. communication) urological surgical skills. Whist numerous studies have assessed the face, content and construct validity of various urological simulators, further work needs to be undertaken to determine whether the skills learnt actually improve trainee performance in the operating room. Then, educators will be able to make informed decisions about whether these resource demanding (financially and in terms of demands on faculty) simulators are a worthwhile educational tool. Although further investigation is required, urological simulators appear to have a considerable role for developing both technical and non-technical urological skills in an increasingly restricted educational environment in modern urogynecology.

    1993-01-01

    A drawback to live-action training simulations is the need to gather a large group of participants in order to train a few individuals. One solution to this difficulty is the use of computer-controlled agents in a virtual training environment. This allows a human participant to be replaced by a virtual, or simulated, agent when only limited responses are needed. Each agent possesses a specified set of behaviors and is capable of limited autonomous action in response to its environment or the direction of a human trainee. The paper describes these agents in the context of a simulated hostage rescue training session, involving two human rescuers assisted by three virtual (computer-controlled) agents and opposed by three other virtual agents.

    The Advanced Test Reactor (ATR) Simulator at the Test Reactor Area of the Idaho National Engineering Laboratory (INEL) has recently been upgraded to reflect plant installation of a distributed control system (DCS). The ATR Simulator re-design implements traditional needs for software extensibility and plant installation prototyping, but the driving force behind its new design was an instruction requirement for multiple, concurrent-training sessions. Support is provided for up to three concurrent, independent or interacting, training sessions of reactor, balance of plant, and experiment loop operators. This capability has been achieved by modifying the existing design to consistently apply client-server, parent-child, and peer-to-peer processing technologies, and then to encapsulate concurrency software into all interfaces. When the resulting component-oriented design is linked with build and runtime flexibility in a distributed computing environment, traditional needs for extensibility and parallel software and scenario development are satisfied with minimal additional effort. Sensible configuration management practices coupled with the ability to perform piecewise system builds also greatly facilitate prototyping of plant changes prior to installation

    2017-01-01

    Background Workplaces today demand graduates who are prepared with field-specific knowledge, advanced social skills, problem-solving skills, and integration capabilities. Meeting these goals with didactic learning (DL) is becoming increasingly difficult. Enhanced training methods that would better prepare tomorrow’s graduates must be more engaging and game-like, such as feedback based e-learning or simulation-based training, while saving time. Empirical evidence regarding the effectiveness of advanced learning methods is lacking. Objective quantitative research comparing advanced training methods with DL is sparse. Objectives This quantitative study assessed the effectiveness of a computerized interactive simulator coupled with an instructor who monitored students’ progress and provided Web-based immediate feedback. Methods A low-cost, globally accessible, telemedicine simulator, developed at the Technion—Israel Institute of Technology, Haifa, Israel—was used. A previous study in the field of interventional cardiology, evaluating the efficacy of the simulator to enhanced learning via knowledge exams, presented promising results of average scores varying from 94% after training and 54% before training (n=20) with Pe-learning in the field of Ob-Gyn. Results from objective knowledge tests were analyzed using hypothesis testing and model fitting. Results A significant advantage (P=.01) was found in favor of the WOZ training approach. Content type and training audience were not significant. Conclusions This study evaluated the contribution of an integrated teaching environment using a computerized interactive simulator, with an instructor providing immediate Web-based immediate feedback to trainees. Involvement of an instructor in the simulation-based training process provided better learning outcomes that varied training content and trainee populations did not affect the overall learning gains.

    A transportable test simulator is described for a nuclear power plant. The nuclear power plant includes a control panel, a reactor having actuated rods for moving into and out of a reactor for causing the plant to operate, and a control rod network extending between the control panel and the reactor rods. The network serially transmits command words between the panel and rods, and has connecting interfaces at preselected points remote from the control panel between the control panel and rods. The test simulator comprises: a test simulator input for transport to and connection into the network at at least one interface for receiving the serial command words from the network. Each serial command includes an identifier portion and a command portion; means for processing interior of the simulator for the serial command words for identifying that portion of the power plant designated in the identifier portion and processing the word responsive to the command portion of the word after the identification; means for generating a response word responsive to the command portion; and output means for sending and transmitting the response word to the nuclear power plant at the interface whereby the control panel responds to the response word

    The aim of simulator training is to train personnel for control work observing technical and technological regulations of nuclear power plant operation. Training is implemented in two forms: basic training and recurrent training. The daily regime of the training course is divided into theoretical education, simulator training and evaluation. Simulator training is oriented to the preparation of the workplace, presentation, controlled intermittent work and independent control work. (J.C.)

    2006-01-01

    This paper presents a newly developed testing and training simulator (TTS) for automatically diagnosing and tuning the Control Element Drive Mechanism Control System (CEDMCS). TTS includes a new automatic, diagnostic, method for logic control cards and a new tuning method for phase synchronous pulse cards. In Korea Standard Nuclear Power Plants (KSNP). reactor trips occasionally occur due to a damaged logic control card in CEDMCS. However, there is no pre-diagnostic tester available to detect a damaged card in CEDMCS before it causes a reactor trip. Even after the reactor trip occurs, it is difficult to find the damaged card. To find the damaged card. ICT is usually used. ICT is an automated, computer-controlled testing system with measurement capabilities for testing active and passive components, or clusters of components, on printed circuit boards (PCB) and/or assemblies. However, ICT cannot detect a time dependent fault correctly and requires removal of the waterproof mating to perform the test. Therefore, the additional procedure of re-coating the PCB card is required after the test. TTS for CEDMCS is designed based on real plant conditions, both electrically and mechanically. Therefore, the operator can operate the Control Element Drive Mechanism (CEDM), which is mounted on the closure head of the reactor vessel (RV) using the soft control panel in ITS, which duplicates the Main Control Board (MCB) in the Main Control Room (MCR). However, during the generation of electric power in a nuclear power plant, it is difficult to operate the CEDM so a CEDM and Control Element Assembly (CEA) mock-up facility was developed to simulate a real plant CEDM. ITS was used for diagnosing and tuning control logic cards in CEDMCS in the Ulchin Nuclear Power Plant No. 4 during the plant overhaul period. It exhibited good performance in detecting the damaged cards and tuning the phase synchronous pulse cards. In addition, TTS was useful in training the CEDMCS operator by

    1978-07-01

    An attempt was made to establish here the need to incorporate ''Accident Situations'' in Training Simulators, and, to indicate that the modelling of such otherwise complex situations could admit a great deal of simplifications. In most cases, a ''semidynamic'' model to display time dependent flows or Tank levels would do while ESF actuated start/stop or open/close of equipment could be modelled merely ''Live''. Transport delays and Time Constants in most cases are of no significance as are the accuracy considerations of most variables. The systems which need complete Dynamic Simulation are the ones which are always running, such as Pressuriser, RCS, Reactor, and the Steam Generator with the added advantages of the modest accuracy requirements and the plant being shutdown.

    The purpose of this study was to develop and evaluate a virtual exercise training software system (VETSS) capable of providing real-time instruction and exercise feedback during exploration missions. A resistive exercise instructional system was developed using a Microsoft Kinect depth-camera device, which provides markerless 3-D whole-body motion capture at a small form factor and minimal setup effort. It was hypothesized that subjects using the newly developed instructional software tool would perform the deadlift exercise with more optimal kinematics and consistent technique than those without the instructional software. Following a comprehensive evaluation in the laboratory, the system was deployed for testing and refinement in the NASA Extreme Environment Mission Operations (NEEMO) analog.

    2012-01-01

    Laparoscopic simulation training has proven to be effective in developing skills but requires expensive equipment, is a challenge to integrate into a work-hour restricted surgical residency, and may use nonoptimal practice schedules. The purpose of this study was to evaluate the efficacy of laparoscopic skills training at home using inexpensive trainer boxes. Residents (n = 20, postgraduate years 1-5) enrolled in an institutional review board-approved laparoscopic skills training protocol. An instructional video was reviewed, and baseline testing was performed using the fundamentals of laparoscopic surgery (FLS) peg transfer and suturing tasks. Participants were randomized to home training with inexpensive, self-contained trainer boxes or to simulation center training using standard video trainers. Discretionary, goal-directed training of at least 1 hour per week was encouraged. A posttest and retention test were performed. Intragroup and intergroup comparisons as well as the relationship between the suture score and the total training sessions, the time in training, and attempts were studied. Intragroup comparisons showed significant improvement from baseline to the posttest and the retention test. No differences were shown between the groups. The home-trained group practiced more, and the number of sessions correlated with suture retention score (r(2) = .54, P < .039). Home training results in laparoscopic skill acquisition and retention. Training is performed in a more distributed manner and trends toward improved skill retention. Copyright © 2012 Elsevier Inc. All rights reserved.

    2008-06-01

    Training of medical personnel using simulation techniques is an acknowledged measure of process optimization and quality assurance in a clinical setting. In 2006, a simulator-based training of anaesthesiologists was introduced in the University Medical Centre of Schleswig-Holstein, Campus Kiel, Germany. The training was performed on a human patient simulator (Meti, Sarasota, USA) and the course was conducted by instructors and engineers from the Simulation Centre Mainz in an operation room equipped with common anaesthesia devices. Special lectures focused at crisis resource management and human errors were held in separate rooms. Parallel daily trainings of 6 physicians and 4 nurses were conducted during 9 days. The training was offered to the anaesthesia personnel of whole Schleswig-Holstein, Germany. A higher and more balanced overall performance of the participants was determined by the instructor teams in comparison to the training results in their own simulation centre. This improved performance was ascribed to the special circumstances of this training namely the familiar surroundings and team members.

  10. Simulation Training Versus Real Time Console Training for New Flight Controllers

    Science.gov (United States)

    Heaton, Amanda

    2010-01-01

    For new flight controllers, the two main learning tools are simulations and real time console performance training. These benefit the new flight controllers in different ways and could possibly be improved. Simulations: a) Allow for mistakes without serious consequences. b) Lets new flight controllers learn the working style of other new flight controllers. c) Lets new flight controllers eventually begin to feel like they have mastered the sim world, so therefore they must be competent in the real time world too. Real time: a) Shows new flight controllers some of the unique problems that develop and have to be accounted for when dealing with certain payloads or systems. b) Lets new flight controllers experience handovers - gathering information from the previous shift on what the room needs to be aware of and what still needs to be done. c) Gives new flight controllers confidence that they can succeed in the position they are training for when they can solve real anomalies. How Sims could be improved and more like real-time ops for the ISS Operations Controller position: a) Operations Change Requests to review. b) Fewer anomalies (but still more than real time for practice). c) Payload Planning Manager Handover sheet for the E-1 and E-3 reviews. d) Flight note in system with at least one comment to verify for the E-1 and E-3 reviews How the real time console performance training could be improved for the ISS Operations Controller position: a) Schedule the new flight controller to be on console for four days but with a different certified person each day. This will force them to be the source of knowledge about every OCR in progress, everything that has happened in those few days, and every activity on the timeline. Constellation program flight controllers will have to learn entirely from simulations, thereby losing some of the elements that they will need to have experience with for real time ops. It may help them to practice real time console performance training

  11. A Simulation-Based Approach to Training Operational Cultural Competence

    Science.gov (United States)

    Johnson, W. Lewis

    2010-01-01

    Cultural knowledge and skills are critically important for military operations, emergency response, or any job that involves interaction with a culturally diverse population. However, it is not obvious what cultural knowledge and skills need to be trained, and how to integrate that training with the other training that trainees must undergo. Cultural training needs to be broad enough to encompass both regional (culture-specific) and cross-cultural (culture-general) competencies, yet be focused enough to result in targeted improvements in on-the-job performance. This paper describes a comprehensive instructional development methodology and training technology framework that focuses cultural training on operational needs. It supports knowledge acquisition, skill acquisition, and skill transfer. It supports both training and assessment, and integrates with other aspects of operational skills training. Two training systems will be used to illustrate this approach: the Virtual Cultural Awareness Trainer (VCAT) and the Tactical Dari language and culture training system. The paper also discusses new and emerging capabilities that are integrating cultural competence training more strongly with other aspects of training and mission rehearsal.

    Simulation-based education (SBE) is an important training strategy in emergency medicine (EM) postgraduate programs. This study sought to characterize the use of simulation in FRCPC-EM residency programs across Canada. A national survey was administered to residents and knowledgeable program representatives (PRs) at all Canadian FRCPC-EM programs. Survey question themes included simulation program characteristics, the frequency of resident participation, the location and administration of SBE, institutional barriers, interprofessional involvement, content, assessment strategies, and attitudes about SBE. Resident and PR response rates were 63% (203/321) and 100% (16/16), respectively. Residents reported a median of 20 (range 0-150) hours of annual simulation training, with 52% of residents indicating that the time dedicated to simulation training met their needs. PRs reported the frequency of SBE sessions ranging from weekly to every 6 months, with 15 (94%) programs having an established simulation curriculum. Two (13%) of the programs used simulation for resident assessment, although 15 (94%) of PRs indicated that they would be comfortable with simulation-based assessment. The most common PR-identified barriers to administering simulation were a lack of protected faculty time (75%) and a lack of faculty experience with simulation (56%). Interprofessional involvement in simulation was strongly valued by both residents and PRs. SBE is frequently used by Canadian FRCPC-EM residency programs. However, there exists considerable variability in the structure, frequency, and timing of simulation-based activities. As programs transition to competency-based medical education, national organizations and collaborations should consider the variability in how SBE is administered.

  15. A Multiprocessor Operating System Simulator

    Johnston, Gary M.; Campbell, Roy H.

    1988-01-01

    This paper describes a multiprocessor operating system simulator that was developed by the authors in the Fall semester of 1987. The simulator was built in response to the need to provide students with an environment in which to build and test operating system concepts as part of the coursework of a third-year undergraduate operating systems course. Written in C++, the simulator uses the co-routine style task package that is distributed with the AT&T C++ Translator to provide a hierarchy of classes that represents a broad range of operating system software and hardware components. The class hierarchy closely follows that of the 'Choices' family of operating systems for loosely- and tightly-coupled multiprocessors. During an operating system course, these classes are refined and specialized by students in homework assignments to facilitate experimentation with different aspects of operating system design and policy decisions. The current implementation runs on the IBM RT PC under 4.3bsd UNIX.

    Many innovations have been incorporated into the Advanced BWR (ABWR) type control panels. In the BWR Operator Training Center (BTC), we started ABWR operator training using an ABWR full-scope simulator prior to the first ABWR plant's commercial operation. In consideration of the features of the ABWR type control panels, BTC has been conducting ABWR operator training focusing on the following 2 points; (1) Operator training reflecting the differences in the Human-Machine Interface (HMI). The new HMI devices which have the touch-operation function were introduced. These devices have higher operability, however, they require new operational skills. We planned the training program so that operators can fully acquire these skills. Also the compact main console and the new HMI devices made it relatively difficult for the operator crews to grasp visually what an operator was doing. We provide the training to have proper communication skills, and check trainees' operation using monitoring systems for simulator training. (2) Operator training responding to the expanded operation automation system. The scope of the automation system was expanded to reduce the operators' burden. We provide the training to improve the trainees' competence for 'operation and monitoring' suitable to both manual and automatic operational modes. (author)

    2016-03-01

    Health care organizations employ simulation-based team training (SBTT) to improve skill, communication and coordination in a broad range of critical care contexts. Quantitative approaches, such as team performance measurements, are predominantly used to measure SBTTs effectiveness. However, a practical evaluation method that examines how this approach supports cognition and teamwork is missing. We have applied Distributed Cognition for Teamwork (DiCoT), a method for analysing cognition and collaboration aspects of work settings, with the purpose of assessing the methodology's usefulness for evaluating SBTTs. In a case study, we observed and analysed four Emergo Train System® simulation exercises where medical professionals trained emergency response routines. The study suggests that DiCoT is an applicable and learnable tool for determining key distributed cognition attributes of SBTTs that are of importance for the simulation validity of training environments. Moreover, we discuss and exemplify how DiCoT supports design of SBTTs with a focus on transfer and validity characteristics. Practitioner Summary: In this study, we have evaluated a method to assess simulation-based team training environments from a cognitive ergonomics perspective. Using a case study, we analysed Distributed Cognition for Teamwork (DiCoT) by applying it to the Emergo Train System®. We conclude that DiCoT is useful for SBTT evaluation and simulator (re)design.

    2011-01-01

    We present NeuroSim, the prototype of a training simulator for open surgical interventions on the human brain. The simulator is based on virtual reality and uses real-time simulation algorithms to interact with models generated from MRT- or CT-datasets. NeuroSim provides a native interface by using a real surgical microscope and original instruments tracked by a combination of inertial measurement units and optical tracking. Conclusively an immersive environment is generated. In a first step the navigation in an open surgery setup as well as the hand-eye coordination through a microscope can be trained. Due to its modular design further training modules and extensions can be integrated. NeuroSim has been developed in cooperation with the neurosurgical clinic of the University of Heidelberg and the VRmagic GmbH in Mannheim.

  19. Simulation bounds for system availability

    International Nuclear Information System (INIS)

    Tietjen, G.L.; Waller, R.A.

    1976-01-01

    System availability is a dominant factor in the practicality of nuclear power electrical generating plants. A proposed model for obtaining either lower bounds or interval estimates on availability uses observed data on ''n'' failure-to-repair cycles of the system to estimate the parameters in the time-to-failure and time-to-repair models. These estimates are then used in simulating failure/repair cycles of the system. The availability estimate is obtained for each of 5000 samples of ''n'' failure/repair cycles to form a distribution of estimates. Specific percentile points of those simulated distributions are selected as lower simulation bounds or simulation interval bounds for the system availability. The method is illustrated with operational data from two nuclear plants for which an exponential time-to-failure and a lognormal time-to-repair are assumed

    geriatrics encompasses diverse medical, social and ethical challenges requiring a multidimensional, interdisciplinary approach. Recent reports have highlighted failings in the care of older people. It is therefore vital that trainees in geriatrics are afforded opportunities to develop skills in managing this complex population. Simulation has been adopted as a teaching tool in medicine; however, evidence for its use in geriatrics has been limited to small, single-site studies primarily involving role-play or discrete clinical skills training. a standardised, two centre, multimodal, interprofessional, geriatrics simulation training programme was developed using curriculum-mapped scenarios in which the patient perspective was central. Simulation techniques used included high-fidelity patient manikins, actors with integrated clinical skills using part-task trainers and role-play exercises. A mixed-methods evaluation was used to analyse data from participants before and after training. eighty-nine candidates attended 12 similar courses over 2 years. Thematic analysis of candidate feedback was supportive of simulation as a useful tool, with benefits for both technical and non-technical skills. Candidates commented that simulation was a valuable training modality addressing curriculum areas rarely taught formally including continence assessment, end-of-life decisions and multidisciplinary situations. Quantitative analysis of pre- and post-course questionnaires revealed a significant improvement of self-reported confidence in managing geriatric scenarios (mean improvement 11.5%; P geriatrics. Simulation training affords situational learning without compromising patient safety and is an exciting and novel method of delivering teaching for geriatrics that could be integrated into national training curricula. © The Author 2015.

    Full Text Available Endoscopy is one of the most important procedures in diagnosis and treatment of gastrointestinal tract problems. While endoscopic procedure has tremendous benefits, physicians require considerable practice and time to develop competency. Current endoscopic training process involves cognitive learning and hands-on training under the supervision of an expert gastroenterologist. Previous studies have shown that fellow involvement prolongs procedural time and incurs additional expenses to the institution. Moreover, the patient also experiences more discomfort and injury risk. Introduction of training simulator into the training process could reduce the involvement of the patients and thus reduce the risk. Porcine model is commonly used for training in endoscopy due to the similar tactile response to a human gastrointestinal tract. However, information on elastic behavior of pig or human gastrointestinal tract for the engineering purposes was limited. In this study, the modulus of elasticity and ultimate tensile stress data of the pig stomach and intestines, small and large intestines, were measured and compared with multiple rubber stomach and intestines models. Based on the experimental results and experienced gastroenterologists feedback, the proposed dipped rubber composition can provide a satisfactory tactile feedback and could be used to simulate a human gastrointestinal tract for an endoscopic simulation training model.

    This report is based an a review of the literature published on simulator training and on discussions with representatives from the German nuclear power plant operator training schools. A brief description of the organisation and content of the simulator training of control room operators in a number of countries, together with a categorisation of the various types of simulators which are used. The concepts of the systems approach to training and simulator fidelity are discussed. Some general training principles which are considered important for simulator training are summarised. From the available descriptions and analyses of control room operator tasks, the skills (in most general terms) which can be trained on simulators have been identified. Methods for training these skills which are used in the simulator training programmes in various industries and which have been developed in research work in the area of training psychology have been summarised. Using these methods as a basis, the necessary instructor facilities which should be included in the design of a full simulator for the Konvoi generation of nuclear power plants have been derived.

    SCADA (Supervisory Control and Data Acquisition) system simulator is a Human Machine Interface-based software that is able to visualize the process of a plant. This study describes the results of the process of designing a SCADA system simulator that aims to facilitate the operator in monitoring, controlling, handling the alarm, accessing historical data and historical trend in Nuclear Power Plant (NPP) type Fast Breeder Reactor (FBR). This research used simulation to simulate NPP type FBR Kalpakkam in India. This simulator was developed using Wonderware Intouch software 10 and is equipped with main menu, plant overview, area graphics, control display, set point display, alarm system, real-time trending, historical trending and security system. This simulator can properly simulate the principle of energy flow and energy conversion process on NPP type FBR. This SCADA system simulator can be used as training media for NPP type FBR prospective operators.

    This research studies reorientation methodologies in a simulated microgravity environment using an experimental framework to reduce astronaut adaptation time and provide for a safety countermeasure during extravehicular activity. There were 20 subjects (10 men, 10 women, mean age of 23.6 +/- 3.5) who were divided into 2 groups, fully trained and minimally trained, which determined the amount of motion strategy training received. Subjects performed a total of 48 rotations about their pitch, roll, and yaw axes in a suspension system that simulated microgravity. In each trial subjects either rotated 90 degrees in pitch, 90 degrees in roll, or 180 degrees in yaw. Experimental measures include subject coordination, performance time, cognitive workload assessments, and qualitative motion control strategies. Subjects in the fully trained group had better initial performance with respect to performance time and workload scores for the pitch and yaw rotations. Further, trained subjects reached a steady-state performance time in fewer trials than those with minimal training. The subjects with minimal training tended to use motions that were common in an Earth environment since no technique was provided. For roll rotations they developed motions that would have led to significant off-axis (pitch and yaw) rotations in a true microgravity environment. We have shown that certain body axes are easier to rotate about than others and that fully trained subjects had an easier time performing the body rotations than the minimally trained subjects. This study has provided the groundwork for the development of an astronaut motion-control training program.

    Graphics Computer Based Training (GCBT) roles include drilling, tutoring, simulation and problem solving. Of these, Commonwealth Edison uses mainly tutoring, simulation and problem solving. These roles are not separate in any particular program. They are integrated to provide tutoring and part-task simulation, part-task simulation and problem solving, or problem solving tutoring. Commonwealth's Graphics Computer Based Training program was a result of over a year's worth of research and planning. The keys to the program are it's flexibility and control. Flexibility is maintained through stand alone units capable of program authoring and modification for plant/site specific users. Yet, the system has the capability to support up to 31 terminals with a 40 mb hard disk drive. Control of the GCBT program is accomplished through establishment of development priorities and a central development facility (Commonwealth Edison's Production Training Center)

    Communication skills are an important component of the neurosurgery residency training program. We developed a simulation-based training module for neurosurgery residents in which medical, communication and ethical dilemmas are presented by role-playing actors. To assess the first national simulation-based communication skills training for neurosurgical residents. Eight scenarios covering different aspects of neurosurgery were developed by our team: (1) obtaining informed consent for an elective surgery, (2) discharge of a patient following elective surgery, (3) dealing with an unsatisfied patient, (4) delivering news of intraoperative complications, (5) delivering news of a brain tumor to parents of a 5 year old boy, (6) delivering news of brain death to a family member, (7) obtaining informed consent for urgent surgery from the grandfather of a 7 year old boy with an epidural hematoma, and (8) dealing with a case of child abuse. Fifteen neurosurgery residents from all major medical centers in Israel participated in the training. The session was recorded on video and was followed by videotaped debriefing by a senior neurosurgeon and communication expert and by feedback questionnaires. All trainees participated in two scenarios and observed another two. Participants largely agreed that the actors simulating patients represented real patients and family members and that the videotaped debriefing contributed to the teaching of professional skills. Simulation-based communication skill training is effective, and together with thorough debriefing is an excellent learning and practical method for imparting communication skills to neurosurgery residents. Such simulation-based training will ultimately be part of the national residency program.

    The current simulation technology used for neurosurgical training leaves much to be desired. Significant efforts are thoroughly exhausted in hopes of developing simulations that translate to give learners the “real-life” feel. Though a respectable goal, this may not be necessary as the application for simulation in neurosurgical training may be most useful in early learners. The ultimate uniformly agreeable endpoint of improved outcome and patient safety drives these investments. We explore the development, availability, educational taskforces, cost burdens and the simulation advancements in neurosurgical training. The technologies can be directed at achieving early resident milestones placed by the Accreditation Council for Graduate Medical Education. We discuss various aspects of neurosurgery disciplines with specific technologic advances of simulation software. An overview of the scholarly landscape of the recent publications in the realm of medical simulation and virtual reality pertaining to neurologic surgery is provided. We analyze concurrent concept overlap between PubMed headings and provide a graphical overview of the associations between these terms. PMID:28765716

    The International Space Station (ISS) is a co-operative programme among the main world space agencies. The European Space Agency contribution is the Automated Transfer Vehicle and the Columbus Orbital Facility, which is the European laboratory of the ISS. It provides a pressurized environment to house up to ten payload racks containing scientific instruments for the conduct of a broad band of experiments. The astronauts on-board of the ISS interact with the payloads for the preparation and execution of the experiments and before their expedition, they have to train on ground in the most realistic manner. The training is carried out at the European Astronauts Centre in the Columbus Trainer, a complex facility that reproduces the physical layout of the ISS European laboratory and a set of payload racks simulators. These simulators are being developed by Dataspazio with an innovative low-cost approach combining the high realism of the simulation with the flexibility and re-usability of the payloads simulators. The hearth of this approach is the interactive payload Virtual Front-panel Interface. The development of these high-realism training payload simulators incorporate several technological issues such as Digital Light ProcessingTM, projected capacitance touch-screen, high-fidelity graphics and simulation software.

    High-reliability organizations have stressed the importance of non-technical skills for safety and of regularly providing such training to their teams. Recently safety skills training has been applied in the practice of medicine. In this study, we developed and piloted a module using multidisciplinary crisis scenarios in a simulated operating theatre to train entire surgical teams. Twenty teams participated (n = 80); each consisted of a trainee surgeon, anesthetist, operating department practitioner (ODP), and scrub nurse. Crisis scenarios such as difficult intubation, hemorrhage, or cardiac arrest were simulated. Technical and non-technical skills (leadership, communication, team skills, decision making, and vigilance), were assessed by clinical experts and by two psychologists using relevant technical and human factors rating scales. Participants received technical and non-technical feedback, and the whole team received feedback on teamwork. Trainees assessed the training favorably. For technical skills there were no differences between surgical trainees' assessment scores and the assessment scores of the trainers. However, nurses overrated their technical skill. Regarding non-technical skills, leadership and decision making were scored lower than the other three non-technical skills (communication, team skills, and vigilance). Surgeons scored lower than nurses on communication and teamwork skills. Surgeons and anesthetists scored lower than nurses on leadership. Multidisciplinary simulation-based team training is feasible and well received by surgical teams. Non-technical skills can be assessed alongside technical skills, and differences in performance indicate where there is a need for further training. Future work should focus on developing team performance measures for training and on the development and evaluation of systematic training for technical and non-technical skills to enhance team performance and safety in surgery.

    Research of adaptive individual and team-based training has been analyzed and helped find out that both in Russia and abroad, individual and team-based training and retraining of AASTM operators usually includes: production training, training of general computer and office equipment skills, simulator training including virtual simulators which use computers to simulate real-world manufacturing situation, and, as a rule, the evaluation of AASTM operators’ knowledge determined by completeness and adequacy of their actions under the simulated conditions. Such approach to training and re-training of AASTM operators stipulates only technical training of operators and testing their knowledge based on assessing their actions in a simulated environment.

    Full Text Available Current system of medical education in Ukraine needs improvement and reforms in order to enhance the proficiency of doctors and paramedics. Training of practical/technical skills, communication, as well as teamwork skills is considerably important.The use of simulation techniques and methods in medical education is called simulation training in medicine. Medical skills are acquired through cognitive (knowledge and psychomotor (practice skills. The first medical simulation centers appeared in Ukraine in 2006 according to the order of the Ministry of Health Care of Ukraine.On June 20, 2013, a new simulation training center was opened in Ivano-Frankivsk on the base of Regional Perinatal Center. Similar medical simulation centers were opened in the second half of 2013 in Volyn and Vinnytsia regions under the Ukrainian-Swiss Mother and Child Health Programme, which started in the area of perinatology. Their goal is to improve the teamwork of all specialists involved in the process of delivery and neonatal intensive care,as well as to engage internship doctors and senior medical students in clinical skills training programmes.The use of simulation techniques and training programs offers a powerful platform to study and practice clinical reasoning behaviors and patterns.

    Above Real-Time Training (ARTT) is the training acquired on a real time simulator when it is modified to present events at a faster pace than normal. The experiments related to training of pilots performed by NASA engineers (Kolf in 1973, Hoey in 1976) and others (Guckenberger, Crane and their associates in the nineties) have shown that in comparison with the real time training (RTT), ARTT provides the following benefits: increased rate of skill acquisition, reduced simulator and aircraft training time, and more effective training for emergency procedures. Two sets of experiments have been performed; they are reported in professional conferences and the respective papers are included in this report. The retention of effects of ARTT has been studied in the first set of experiments and the use of ARTT as top-off training has been examined in the second set of experiments. In ARTT, the pace of events was 1.5 times the pace in RTT. In both sets of experiments, university students were trained to perform an aerial gunnery task. The training unit was equipped with a joystick and a throttle. The student acted as a nose gunner in a hypothetical two place attack aircraft. The flight simulation software was installed on a Universal Distributed Interactive Simulator platform supplied by ECC International of Orlando, Florida. In the first set of experiments, two training programs RTT or ART7 were used. Students were then tested in real time on more demanding scenarios: either immediately after training or two days later. The effects of ARTT did not decrease over a two day retention interval and ARTT was more time efficient than real time training. Therefore, equal test performance could be achieved with less clock-time spent in the simulator. In the second set of experiments three training programs RTT or ARTT or RARTT, were used. In RTT, students received 36 minutes of real time training. In ARTT, students received 36 minutes of above real time training. In RARTT, students

    Patient safety became paramount in medicine as well as in emergency medicine after it was recognized that preventable, adverse events significantly contributed to morbidity and mortality during hospital stay. The underlying errors cannot usually be explained by medical technical inadequacies only but are more due to difficulties in the transition of theoretical knowledge into tasks under the conditions of clinical reality. Crew Resource Management and Human Factors which determine safety and efficiency of humans in complex situations are suitable to control such sources of error. Simulation significantly improved safety in high reliability organizations, such as the aerospace industry.Thus, simulator-based team training has also been proposed for medical areas. As such training is consuming in cost, time and human resources, the question of the cost-benefit ratio obviously arises. This review outlines the effects of simulator-based team training on patient safety. Such course formats are not only capable of creating awareness and improvements in safety culture but also improve technical team performance and emphasize team performance as a clinical competence. A few studies even indicated improvement of patient-centered outcome, such as a reduced rate of adverse events but further studies are required in this respect. In summary, simulator-based team training should be accepted as a suitable strategy to improve patient safety.

    1998-06-01

    Deep nerve regional anesthesiology procedures, such as the celiac plexus block, are challenging to learn. The current training process primarily involves studying anatomy and practicing needle insertion is cadavers. Unfortunately, the training often continues on the first few patients subjected to the care of the new resident. To augment the training, we have developed a virtual reality surgical simulation designed to provide an immersive environment in which an understanding of the complex 3D relationships among the anatomic structures involved can be obtained and the mechanics of the celiac block procedure practiced under realistic conditions. Study of the relevant anatomy is provided by interactive 3D visualization of patient specific data nd the practice simulated using a head mounted display, a 6 degree of freedom tracker, and a haptic feedback device simulating the needle insertion. By training in a controlled environment, the resident may practice procedures repeatedly without the risks associated with actual patient procedures, and may become more adept and confident in the ability to perform nerve blocks. The resident may select a variety of different nerve block procedures to practice, and may place the virtual patient in any desired position and orientation. The preliminary anatomic models used in the simulation have been computed from the Visible Human Male; however, patient specific models may be generated from patient image data, allowing the physician to evaluate, plan, and practice difficult blocks and/or understand variations in anatomy before attempting the procedure on any specific patient.

    Full Text Available In the work, the learning process with the use of a simulator was studied. In this case, both the design and algorithmic content of the simulator, as well as the trainee, must pass their part of the path, only in this case the result of learning is maximized. Theoretically, it is shown that the effectiveness of simulator training is primarily a function of the cognitive-operational and professional-personal aspects of the trainee's competence. The experiment confirmed that, despite the differences above the indicated qualities, the result can be estimated as the sum of their estimates.

    A review of the evolution of the control room team is necessary to understand team training needs. As control room responsibilities have increased and members have been added to the operating crews, teamwork and strong leadership has become crucial to the efficiency of these operating crews. In order to conduct effective team training in a simulated control room, it is essential that the fundamental principles of role definition and common team values are fully developed. The diagnostics model used to develop problem-solving skills must be adaptable to the dynamic environment of the control room. Once the fundamental principles of team building and a good diagnostics model are mastered, many training techniques using a simulator are available to perfect the development of team building and diagnostic skills

    Full Text Available This paper presents an arrangement method of FEA modeling knowledge by using a design pattern methodology, and deals with an estimation method of FEA training scenario. The prototype support system and its training knowledge can be arranged and classified in several patterns, while the mechanics of a beam structure has been picked up as an example of training subject. Essential evaluation problems were prepared for checking the synthetic achievement and the effectivity of training support system onto any beginners of the code called MARC/MENTAT has been investigated. Through the simulation with the prototype training support system, an evaluation model as the synthetic achievement test for any training scenario was shown with the degree vector. Observing the reusability of training programs, the compression rate of iterated common operations was estimated for the prototype training support system.

    2017-08-01

    To develop an endovascular aneurysm repair (EVAR) simulation system using three dimensional (3D) printed aneurysms, and to evaluate the impact of patient specific training prior to EVAR on the surgical performance of vascular surgery residents in a university hospital in Brazil. This was a prospective, controlled, single centre study. During 2015, the aneurysms of patients undergoing elective EVAR at São Paulo University Medical School were 3D printed and used in training sessions with vascular surgery residents. The 3D printers Stratasys-Connex 350, Formlabs-Form1+, and Makerbot were tested. Ten residents were enrolled in the control group (five residents and 30 patients in 2014) or the training group (five residents and 25 patients in 2015). The control group performed the surgery under the supervision of a senior vascular surgeon (routine procedure, without simulator training). The training group practised the surgery in a patient specific simulator prior to the routine procedure. Objective parameters were analysed, and a subjective questionnaire addressing training utility and realism was answered. Patient specific training reduced fluoroscopy time by 30% (mean 48 min, 95% confidence interval [CI] 40-58 vs. 33 min, 95% CI 26-42 [p printers Form1+ (using flexible resin) and Makerbot (using silicone) provided the best performance based on simulator quality and cost. An EVAR simulation system using 3D printed aneurysms was feasible. The best results were obtained with the 3D printers Form1+ (using flexible resin) and Makerbot (using silicone). Patient specific training prior to EVAR at a university hospital in Brazil improved residents' surgical performance (based on fluoroscopy time, surgery time, and volume of contrast used) and increased their self confidence.

    Simulated patient care has gained acceptance as a medical education tool but is underused in surgical training. To improve resident clinical management in critical situations relevant to the surgical patient, high-fidelity full patient simulation training was instituted at Baystate Medical Center in 2005 and developed during successive years. We define surgical patient simulation as clinical management performed in a high fidelity environment using a manikin simulator. This technique is intended to be specifically modeled experiential learning related to the knowledge, skills, and behaviors that are fundamental to patient care. We report 3 academic years' use of a patient simulation curriculum. Learners were PGY 1-3 residents; 26 simulated patient care experiences were developed based on (1) designation as a critical management problem that would otherwise be difficult to practice, (2) ability to represent the specific problem in simulation, (3) relevance to the American Board of Surgery (ABS) certifying examination, and/or (4) relevance to institutional quality or morbidity and mortality reports. Although training started in 2005, data are drawn from the period of systematic and mandatory training spanning from July 2006 to June 2009. Training occurred during 1-hour sessions using a computer-driven manikin simulator (METI, Sarasota, Florida). Educational content was provided either before or during presimulation briefing sessions. Scenario areas included shock states, trauma and critical care case management, preoperative processes, and postoperative conditions and complications. All sessions were followed by facilitated debriefing. Likert scale-based multi-item assessments of core competency in medical knowledge, patient care, diagnosis, management, communication, and professionalism were used to generate a performance score for each resident for each simulation (percentage of best possible score). Performance was compared across PGYs by repeated

    Simulation-based training (SBT) has become a standard for medical education. However, the efficacy of simulation based training in airway management education remains unclear. The aim of this study was to evaluate all published evidence comparing the effectiveness of SBT for airway management versus non-simulation based training (NSBT) on learner and patient outcomes. Systematic review with meta-analyses were used. Data were derived from PubMed, EMBASE, CINAHL, Scopus, the Cochrane Controlled Trials Register and Cochrane Database of Systematic Reviews from inception to May 2016. Published comparative trials that evaluated the effect of SBT on airway management training in compared with NSBT were considered. The effect sizes with 95% confidence intervals (CI) were calculated for outcomes measures. Seventeen eligible studies were included. SBT was associated with improved behavior performance [standardized mean difference (SMD):0.30, 95% CI: 0.06 to 0.54] in comparison with NSBT. However, the benefits of SBT were not seen in time-skill (SMD:-0.13, 95% CI: -0.82 to 0.52), written examination score (SMD: 0.39, 95% CI: -0.09 to 0.86) and success rate of procedure completion on patients [relative risk (RR): 1.26, 95% CI: 0.96 to 1.66]. SBT may be not superior to NSBT on airway management training.

    Full Text Available In the sport science fields, for a long time there are various attempts to explore more advanced technology in order to collect kinds of information concerned during athletes training and matches. In the paper, a footwork training and testing system has been developed by adopting the advanced technology of Wireless Sensor Network (WSN. The system is comprised of some wireless senor nodes and gateways, system control software and so on. By means of the system, the daily footwork training methods and modes will be simulated to automatically guide the training of the athletes, at the same time the training data concerned will be automatically recorded, including moving velocity, moving frequency and success average, moving exercise duration and so on, and it is facilitate to evaluate digitally the training and testing effects for coaches and athletes. The system will bring about an auxiliary means in sport science training and research, make coaches and researchers have more options for the technical and information forms, and provide the technology foundation for synchronizing and intermingling the training and testing smoothly.

    The integration of simulation into residency programs has been slower in obstetrics and gynaecology than in other surgical specialties. The goal of this study was to evaluate the current use of simulation in obstetrics and gynaecology residency programs in Canada. A 19-question survey was developed and distributed to all 16 active and accredited obstetrics and gynaecology residency programs in Canada. The survey was sent to program directors initially, but on occasion was redirected to other faculty members involved in resident education or to senior residents. Survey responses were collected over an 18-month period. Twelve programs responded to the survey (11 complete responses). Eleven programs (92%) reported introducing an obstetrics and gynaecology simulation curriculum into their residency education. All respondents (100%) had access to a simulation centre. Simulation was used to teach various obstetrical and gynaecological skills using different simulation modalities. Barriers to simulation integration were primarily the costs of equipment and space and the need to ensure dedicated time for residents and educators. The majority of programs indicated that it was a priority for them to enhance their simulation curriculum and transition to competency-based resident assessment. Simulation training has increased in obstetrics and gynaecology residency programs. The development of formal simulation curricula for use in obstetrics and gynaecology resident education is in early development. A standardized national simulation curriculum would help facilitate the integration of simulation into obstetrics and gynaecology resident education and aid in the shift to competency-based resident assessment. Obstetrics and gynaecology residency programs need national collaboration (between centres and specialties) to develop a standardized simulation curriculum for use in obstetrics and gynaecology residency programs in Canada.

    The International Space Station demonstrates the greatest capabilities of human ingenuity, international cooperation and technology development. The complexity of this space structure is unprecedented; and training astronaut crews to maintain all its systems, as well as perform a multitude of research experiments, requires the most advanced training tools and techniques. Computer simulation and virtual environments are currently used by astronauts to train for robotic arm manipulations and extravehicular activities; but now, with the latest computer technologies and recent successes in areas of medical simulation, the capability exists to train astronauts for more hands-on research tasks using immersive virtual environments. We have developed a new technology, the Virtual Glovebox (VGX), for simulation of experimental tasks that astronauts will perform aboard the Space Station. The VGX may also be used by crew support teams for design of experiments, testing equipment integration capability and optimizing the procedures astronauts will use. This is done through the 3D, desk-top sized, reach-in virtual environment that can simulate the microgravity environment in space. Additional features of the VGX allow for networking multiple users over the internet and operation of tele-robotic devices through an intuitive user interface. Although the system was developed for astronaut training and assisting support crews, Earth-bound applications, many emphasizing homeland security, have also been identified. Examples include training experts to handle hazardous biological and/or chemical agents in a safe simulation, operation of tele-robotic systems for assessing and diffusing threats such as bombs, and providing remote medical assistance to field personnel through a collaborative virtual environment. Thus, the emerging VGX simulation technology, while developed for space- based applications, can serve a dual use facilitating homeland security here on Earth.

    One of the best ways to enhance space systems simulation fidelity is to leverage off of (reuse) existing high-fidelity simulations. But what happens when the model you would like to reuse is in a different coding language or other barriers arise that make one want to just start over with a clean sheet of paper? Three diverse system-level simulation reuse case studies are described based on experience to date in the development of NASA's Space Station Training Facility (SSTF) at the Johnson Space Center in Houston, Texas. Case studies include (a) the Boeing/Rocketdyne-provided Electrical Power Simulation (EPSIM), (b) the NASA Automation and Robotics Division-provided TRICK robotics systems model, and (c) the Russian Space Agency- provided Russian Segment Trainer. In each case, there was an initial tendency to dismiss simulation reuse candidates based on an apparent lack of suitability. A more careful examination based on a more structured assessment of architectural and requirements-oriented representations of the reuse candidates revealed significant reuse potential. Specific steps used to conduct the detailed assessments are discussed. The steps include the following: 1) Identifying reuse candidates; 2) Requirements compatibility assessment; 3) Maturity assessment; 4) Life-cycle cost determination; and 5) Risk assessment. Observations and conclusions are presented related to the real cost of system-level simulation component reuse. Finally, lessons learned that relate to maximizing the benefits of space systems simulation reuse are shared. These concepts should be directly applicable for use in the development of space systems simulations in the future.

    Surgery of the spine is associated with the possible complication of permanent nerve injury. Neurophysiological monitoring is widely used during spine surgery to decrease the incidence and severity of neurologic injury. A profound understanding of physiological and pharmacological factors influencing evoked potentials is expected from the anesthesia provider. Because demonstration and teaching of all somatosensory evoked potential (SSEP) changes is difficult in the clinical environment, we developed human patient simulator scenarios to facilitate the anesthesia resident training in neurophysiological monitoring. A SSEP simulation for resident training was created using flash animation in a patient simulation program and is the focus of this report. Feedback from participants (anesthesia residents) was obtained by a postscenario survey. This report provides a detailed description of the scenario and computer program. The survey findings indicated that the simulation session is an effective teaching method of SSEP monitoring. Flash animation integration into a patient simulation program for SSEP monitoring appears to be an effective method for anesthesia resident education in neurophysiological monitoring.

    Full Text Available In this article, we present approaches to interactive simulations of biohybrid systems. These simulations are comprised of two major computational components: (1 agent-based developmental models that retrace organismal growth and unfolding of technical scaffoldings and (2 interfaces to explore these models interactively. Simulations of biohybrid systems allow us to fast forward and experience their evolution over time based on our design decisions involving the choice, configuration and initial states of the deployed biological and robotic actors as well as their interplay with the environment. We briefly introduce the concept of swarm grammars, an agent-based extension of L-systems for retracing growth processes and structural artifacts. Next, we review an early augmented reality prototype for designing and projecting biohybrid system simulations into real space. In addition to models that retrace plant behaviors, we specify swarm grammar agents to braid structures in a self-organizing manner. Based on this model, both robotic and plant-driven braiding processes can be experienced and explored in virtual worlds. We present an according user interface for use in virtual reality. As we present interactive models concerning rather diverse description levels, we only ensured their principal capacity for interaction but did not consider efficiency analyzes beyond prototypic operation. We conclude this article with an outlook on future works on melding reality and virtuality to drive the design and deployment of biohybrid systems.

    Computer-assisted interventions (CAI) aim to increase the effectiveness, precision and repeatability of procedures to improve surgical outcomes. The presence and motion of surgical tools is a key information input for CAI surgical phase recognition algorithms. Vision-based tool detection and recognition approaches are an attractive solution and can be designed to take advantage of the powerful deep learning paradigm that is rapidly advancing image recognition and classification. The challenge for such algorithms is the availability and quality of labelled data used for training. In this Letter, surgical simulation is used to train tool detection and segmentation based on deep convolutional neural networks and generative adversarial networks. The authors experiment with two network architectures for image segmentation in tool classes commonly encountered during cataract surgery. A commercially-available simulator is used to create a simulated cataract dataset for training models prior to performing transfer learning on real surgical data. To the best of authors' knowledge, this is the first attempt to train deep learning models for surgical instrument detection on simulated data while demonstrating promising results to generalise on real data. Results indicate that simulated data does have some potential for training advanced classification methods for CAI systems.

    1998-09-01

    Current flight simulators and trainers do not provide acceptable levels of visual display performance (performance that would allow ground based trainers to economically replace aircraft flying training) for many air-to-air and air-to- ground training scenarios. Ground training for pilots could be made significantly more realistic, allowing the ground-based curricula to be enlarged. The enhanced ground based training could then more readily augment actual aircraft flying (training) time. This paper presents the technology need and opportunity to create a new class of immersive simulator- trainer systems having some 210 million pixels characterized especially by a 20-20 visual acuity synthetic vision system having some 150 million pixels. The same new display technology base is needed for planned crew stations for uninhabited combat air vehicles (UCAV), advanced aircraft cockpits and mission crewstations, and for the space plane.

    Directory of Open Access Journals (Sweden)

    Zhibin Jiang

    2015-04-01

    Full Text Available Understanding the nature of rail transit dwell time has potential benefits for both the users and the operators. Crowded passenger trains cause longer dwell times and may prevent some passengers from boarding the first available train that arrives. Actual dwell time and the process of passenger alighting and boarding are interdependent through the sequence of train stops and propagated delays. A comprehensive and feasible dwell time simulation model was developed and optimized to address the problems associated with scheduled timetables. The paper introduces the factors that affect dwell time in urban rail transit systems, including train headway, the process and number of passengers alighting and boarding the train, and the inability of train doors to properly close the first time because of overcrowded vehicles. Finally, based on a time-driven micro-simulation system, Shanghai rail transit Line 8 is used as an example to quantify the feasibility of scheduled dwell times for different stations, directions of travel and time periods, and a proposed dwell time during peak hours in several crowded stations is presented according to the simulation results.

    To evaluate the reported outcomes for measuring the effectiveness of simulation during knee arthroscopy training and determine the consistency of reporting and validation of simulation used in knee arthroscopy training. Four databases (MEDLINE, Embase, CINAHL, and Cochrane Central Register of Controlled Trials) were screened for studies involving knee arthroscopy simulation training. Inclusion and exclusion criteria were applied to the searched studies, and a quality assessment was completed for included studies. The reviewers searched the references list in each of the eligible studies to identify other relevant studies that was not captured by our search strategy. We identified 13 eligible studies. The mean number of participants per study was 24 (range: 9 to 42 participants). The 3 most commonly reported surgical skills were the mean time to perform the task (100%), the visualization and probing tasks (77%), and the number of cartilage collisions with measurement of the surgical force (46%). The most commonly described measurement instruments included the Simulation Built-In Scoring System (54%), motion analysis system (23%), and Basic Arthroscopic Knee Skill Scoring System global rating scale (15%). The most frequently reported type of validity for the simulator was construct validity (54%) and concurrent validity (31%). Moreover, construct validity (69%) and concurrent validity (54%) were the most commonly reported type of validity for the measurement instrument. There is significant variation in reported learning outcomes and measurement instruments for evaluating the effectiveness of knee arthroscopic simulation-based education. Despite this, time to perform a task was the most commonly reported skill-evaluating outcome of simulation. The included studies in this review were of variable strength in terms of their evidence and methodologic quality. This study highlights the need for consistent outcome reporting after arthroscopic simulation training. Level IV

    2012-03-01

    The United States military is increasingly pursuing advanced live, virtual, and constructive (LVC) training systems for reduced cost, greater training flexibility, and decreased training times. Combining the advantages of realistic training environments and virtual worlds, mixed reality LVC training systems can enable live and virtual trainee interaction as if co-located. However, LVC interaction in these systems often requires constructing immersive environments, developing hardware for live-virtual interaction, tracking in occluded environments, and an architecture that supports real-time transfer of entity information across many systems. This paper discusses a system that overcomes these challenges to empower LVC interaction in a reconfigurable, mixed reality environment. This system was developed and tested in an immersive, reconfigurable, and mixed reality LVC training system for the dismounted warfighter at ISU, known as the Veldt, to overcome LVC interaction challenges and as a test bed for cuttingedge technology to meet future U.S. Army battlefield requirements. Trainees interact physically in the Veldt and virtually through commercial and developed game engines. Evaluation involving military trained personnel found this system to be effective, immersive, and useful for developing the critical decision-making skills necessary for the battlefield. Procedural terrain modeling, model-matching database techniques, and a central communication server process all live and virtual entity data from system components to create a cohesive virtual world across all distributed simulators and game engines in real-time. This system achieves rare LVC interaction within multiple physical and virtual immersive environments for training in real-time across many distributed systems.

    2014-01-01

    Full Text Available Train operation is a complex nonlinear process; it is difficult to establish accurate mathematical model. In this paper, we design ATO speed controller based on the input and output data of the train operation. The method combines multimodeling with predictive functional control according to complicated nonlinear characteristics of the train operation. Firstly, we cluster the data sample by using fuzzy-c means algorithm. Secondly, we identify parameter of cluster model by using recursive least square algorithm with forgetting factor and then establish the local set of models of the process of train operation. Then at each sample time, we can obtain the global predictive model about the system based on the weighted indicators by designing a kind of weighting algorithm with error compensation. Thus, the predictive functional controller is designed to control the speed of the train. Finally, the simulation results demonstrate the effectiveness of the proposed algorithm.

    The aim of this study was to assess the gynecology obstetric residents training on a birth simulator. This is a prospective monocentric study, which had included residents at the beginning of their formation and performed on SIMone™, 3B SCIENTIFIC(®) birth simulator. It had included four sessions (supervised by two seniors registrar): two on instrumental extraction (vacuum and forceps) and two on labor monitoring. The two sessions were performed at one month. A theoretical formation was accomplished after the first assessment. Three assessments were performed based on two score scales (extraction and labor monitoring). A free training was allowed at each extraction session. Twelve interns were included in this study.

    Millions of complex physics-based simulations are required for design of an aerospace vehicle. These simulations are usually performed by highly trained and skilled analysts, who execute, monitor, and steer each simulation. Analysts rely heavily on their broad experience that may have taken 20-30 years to accumulate. In addition, the simulation software is complex in nature, requiring significant computational resources. Simulations of system of systems become even more complex and are beyond human capacity to effectively learn their behavior. IBM has developed machines that can learn and compete successfully with a chess grandmaster and most successful jeopardy contestants. These machines are capable of learning some complex problems much faster than humans can learn. In this paper, we propose using artificial neural network to train knowledge bots to identify the idiosyncrasies of simulation software and recognize patterns that can lead to successful simulations. We examine the use of knowledge bots for applications of computational fluid dynamics (CFD), trajectory analysis, commercial finite-element analysis software, and slosh propellant dynamics. We will show that machine learning algorithms can be used to learn the idiosyncrasies of computational simulations and identify regions of instability without including any additional information about their mathematical form or applied discretization approaches.

    2013-05-01

    The microworld simulator paradigm is well established in the areas of ship-navigation and spaceflight, but has yet to be applied to rail. This paper presents a case study aiming to address this research gap, and describes the development of a train driving microworld as a tool to overcome some common research barriers. A theoretical framework for microworld design is tested and used to explore some key methodological issues and characteristics of train driving, enhancing theory development and providing a useful guideline for the designers of other collision-avoidance systems. A detailed description is given of the ATREIDES (Adaptive Train Research Enhanced Information Display & Environment Simulator) microworld, which simulates the work environment of a train driver in a high-speed passenger train. General indications of the testable driving scenarios that may be simulated are given, and an example of an ATREIDES-based study is presented to illustrate its applied research potential. The article concludes with a review of the design process, considers some strengths and limitations, and explores some future initiatives towards enhancing the systematic study of rail research in the human factors community.

    Previous acupressure studies have yielded varying results. This could be due to differences in the amount of pressure applied to the acupressure point (acupoint) by study personnel within a study as well as between studies. Standardizing the level of pressure applied at an acupoint could improve clinical care and future research. As part of an ongoing randomized clinical trial of postoperative acupressure, five trainees were asked to perform 2 minutes of acupressure and light touch sessions on a simulator. The applied weight was recorded every minute. Individual skill assessment was performed using cumulative sum analysis. Six pretraining and 20 posttraining measurements in each acupressure and light touch group were compared with an expert's simulation values. Before training (baseline), there was significant difference in applied weight (grams) between the expert [5705 (636)] and five trainees [2998 (798), P = 0.004]. Four of the five trainees crossed the lower decision limit assessing proficiency in the acupressure group, and all five trainees were successful in the light touch group. The trainees' average number of measurements needed to cross the lower decision limit (H0), that is, defining that an individual failure rate does not statistically differ from the acceptable failure rate, was 21.3 measurements for acupressure. After this feedback simulation, trainees' scores showed no significant difference (P > 0.05) when assessed against the expert. Feedback simulation for acupressure training and skill assessment, evaluated by cumulative sum analysis, may help in improving the standardization of acupressure therapy performed during clinical practice or research.

    Advanced medical education simulators are broadly used today to train both technical/procedural and team-based skills. While there is convincing evidence of the benefits of training technical skills, this is not the case for team-based skills. Research on medical expertise could drive the creation of a new regime of simulation-based team training. The new regime includes first the understanding of complex systems such as the hospital and the operating room; then the performance of work-place assessment; thirdly, the deliberate training of weaknesses and team performance skills; and lastly the understanding of the underlying mechanisms of team competence. A new regime of deliberate training proposed by the author, which would need to be evaluated and validated, could elucidate the underlying mechanisms of team competence while providing evidence of the effect of simulation-based team training.

    CTMS is a database that links information needed to maintain a five-phase approach to training-analysis, design, development, implementation, and evaluation independent of training program design. CTMS is designed using R-Base, and SQL compliant software platform. Information is logically entered and linked in CTMS. Each task is linked directly to a performance objective, which, in turn, is linked to its respective test items, In addition, tasks performance objectives, enabling objectives, and test items are linked to their associated reference documents. CTMS keeps all information up to date since it automatically sorts, files and links all data; CTMS included key word and reference document searches.

  18. Developing Collective Training for Small Unmanned Aerial Systems Employment

    2010-01-01

    The projected use of small unmanned aerial systems (SUAS) in military operations will produce training requirements which go beyond current capabilities. The paper describes the development of prototype training procedures and accompanying research simulations to address this need. We initially constructed a testbed to develop simulation-based training for an SUAS operator equipped with a simulated vertical-lift and land SUAS. However, the required training will go beyond merely training an operator how to pilot an SUAS. In addition to tactics, techniques, and procedures for employment of SUASs, collective training methods must be trained. Moreover, the leader of a unit equipped with SUAS will need to learn how to plan missions which incorporate the SUAS, and take into account air space and frequency management considerations. The demands of the task require the leader to allocate personnel to the SUAS mission, communicate and coordinate with those personnel during the mission, and make use of the information provided. To help address these training issues, we expanded our research testbed to include a command and control node (C2 node), to enable communications between a leader and the SUAS operator. In addition, we added a virtual environment in which dismounted infantry missions can be conducted. This virtual environment provides the opportunity for interactions among human-controlled avatars and non-player characters (NPCs), plus authoring tools to construct scenarios. Using these NPCs, a collective exercise involving friendly, enemy, and civilian personnel can be conducted without the need for a human role-player for every entity. We will describe the results of our first experiment, which examined the ability of players to negotiate use of the C2 node and the virtual environment at the same time, in order to see if this is a feasible combination of tools for training development.

  19. Adherence and perceptions regarding simulation training in undergraduate health Sciences

    Directory of Open Access Journals (Sweden)

    Fernando Perpétuo Elias

    Full Text Available BACKGROUND: Simulation techniques are spreading rapidly in medicine. Suc h resources are increasingly concentrated in Simulation Laboratories. The MSRP-USP is structuring such a laboratory and is interested in the prevalence of individual initiatives that could be centralized there. The MSRP-USP currently has five full-curriculum courses in the health sciences: Medicine, Speech Therapy, Physical Therapy, Nutrition, and Occupational Therapy, all consisting of core disciplines. GOAL: To determine the prevalence of simulation techniques in the regular courses at MSRP-USP. METHODS: Coordinators of disciplines in the various courses were interviewed using a specifically designed semi-structured questionnaire, and all the collected data were stored in a dedicated database. The disciplines were grouped according to whether they used (GI or did not use (GII simulation resources. RESULTS AND DISCUSSION: 256 disciplines were analyzed, of which only 18.3% used simulation techniques, varying according to course: Medicine (24.7.3%, Occupational Therapy (23.0%, Nutrition (15.9%, Physical Therapy (9.8%, and Speech Therapy (9.1%. Computer simulation programs predominated (42.5% in all five courses. The resources were provided mainly by MSRP-USP (56.3%, with additional funding coming from other sources based on individual initiatives. The same pattern was observed for maintenance. There was great interest in centralizing the resources in the new Simulation Laboratory in order to facilitate maintenance, but there was concern about training and access to the material. CONCLUSIONS: 1 The MSRP-USP simulation resources show low complexity and are mainly limited to computer programs; 2 Use of simulation varies according to course, and is most prevalent in Medicine; 3 Resources are scattered across several locations, and their acquisition and maintenance depend on individual initiatives rather than central coordination or curricular guidelines

  20. A study on optimization of hybrid drive train using Advanced Vehicle Simulator (ADVISOR)

    Science.gov (United States)

    Same, Adam; Stipe, Alex; Grossman, David; Park, Jae Wan

    This study investigates the advantages and disadvantages of three hybrid drive train configurations: series, parallel, and "through-the-ground" parallel. Power flow simulations are conducted with the MATLAB/Simulink-based software ADVISOR. These simulations are then applied in an application for the UC Davis SAE Formula Hybrid vehicle. ADVISOR performs simulation calculations for vehicle position using a combined backward/forward method. These simulations are used to study how efficiency and agility are affected by the motor, fuel converter, and hybrid configuration. Three different vehicle models are developed to optimize the drive train of a vehicle for three stages of the SAE Formula Hybrid competition: autocross, endurance, and acceleration. Input cycles are created based on rough estimates of track geometry. The output from these ADVISOR simulations is a series of plots of velocity profile and energy storage State of Charge that provide a good estimate of how the Formula Hybrid vehicle will perform on the given course. The most noticeable discrepancy between the input cycle and the actual velocity profile of the vehicle occurs during deceleration. A weighted ranking system is developed to organize the simulation results and to determine the best drive train configuration for the Formula Hybrid vehicle. Results show that the through-the-ground parallel configuration with front-mounted motors achieves an optimal balance of efficiency, simplicity, and cost. ADVISOR is proven to be a useful tool for vehicle power train design for the SAE Formula Hybrid competition. This vehicle model based on ADVISOR simulation is applicable to various studies concerning performance and efficiency of hybrid drive trains.

    This is a report of the development process and related technologies of severe accident graphic simulators, required in industrial severe accident management and training. Here, we say 'a severe accident graphic simulator' as a graphics add-in system to existing calculation codes, which can show the severe accident phenomena dynamically on computer screens and therefore which can supplement one of main defects of existing calculation codes. With graphic simulators it is fairly easy to see the total behavior of nuclear power plants, where it was very difficult to see only from partial variable numerical information. Moreover, the fast processing and control feature of a graphic simulator can give some opportunities of predicting the severe accident advancement among several possibilities, to one who is not an expert. Utilizing graphic simulators' we expect operators' and TSC members' physical phenomena understanding enhancement from the realistic dynamic behavior of plants. We also expect that severe accident training course can gain better training effects using graphic simulator's control functions and predicting capabilities, and therefore we expect that graphic simulators will be effective decision-aids tools both in sever accident training course and in real severe accident situations. With these in mind, we have developed a prototype graphic simulator having surveyed related technologies, and from this development experiences we have inspected the possibility to build a severe accident graphic simulator. The prototype graphic simulator is developed under IBM PC WinNT environments and is suited to Uljin 3and4 nuclear power plant. When supplied with adequate severe accident scenario as an input, the prototype can provide graphical simulations of plant safety systems' dynamic behaviors.

    Simulated patients (SPs) are frequently used for training nursing students in communication skills. An acknowledged benefit of using SPs is the opportunity to provide a standardized approach by which participants can demonstrate and develop communication skills. However, relatively little evidence is available on how to best facilitate and evaluate the reliability and accuracy of SPs' performances. The aim of this study is to investigate the effectiveness of an evidenced based SP training framework to ensure standardization of SPs. The training framework was employed to improve inter-rater reliability of SPs. A quasi-experimental study was employed to assess SP post-training understanding of simulation scenario parameters using inter-rater reliability agreement indices. Two phases of data collection took place. Initially a trial phase including audio-visual (AV) recordings of two undergraduate nursing students completing a simulation scenario is rated by eight SPs using the Interpersonal Communication Assessments Scale (ICAS) and Quality of Discharge Teaching Scale (QDTS). In phase 2, eight SP raters and four nursing faculty raters independently evaluated students' (N=42) communication practices using the QDTS. Intraclass correlation coefficients (ICC) were >0.80 for both stages of the study in clinical communication skills. The results support the premise that if trained appropriately, SPs have a high degree of reliability and validity to both facilitate and evaluate student performance in nurse education.

    2007-01-01

    Needle placement into a patient body under guidance of ultrasound is a frequently performed procedure in clinical practice. Safe and successful performance of such procedure requires a high level of spatial reasoning and hand-eye co-ordination skills, which must be developed through intensive practice. In this paper we present a training system designed to improve the skills of interventional radiology trainees in ultrasound-guided needle placement procedures. Key issues involved in the system include surface and volumetric registration, solid texture modelling, spatial calibration, and real-time synthesis and rendering of ultrasound images. Moreover, soft tissue deformation caused by the needle movement and needle cutting is realised using a mass-spring-model approach. These have led to a realistic ultrasound simulation system, which has been shown to be a useful tool for the training of needle insertion procedures. Preliminary results of a construct evaluation study indicate the effectiveness and usefulness of the developed training system.

    Simulator training for nuclear power plant operators in Germany is conducted in The Simulator Center in Essen. The companies operating The Center are KSG/GfS. KSG provides simulators, GfS performs the training. The German Simulator Center is equipped with five simulators in training, nine simulators are under construction and will be ready for training until the beginning of 1997. This institution serves 22 nuclear power plants units in Germany, Switzerland (NPP Goesgen-Daeniken) and the Netherlands (NPP Borssele) and trains 1,800 persons every year. As a common enterprise the company is owned by 12 utilities, which leads to the necessity to prepare common rules and guidelines for simulator specification, training of instructors, assessment of trainees, training material and preparation and methodical running of simulator courses

    This article reports on the face, content, and construct validity of a new realistic composite simulator (Simuldog) used to provide training in canine gastrointestinal flexible endoscopy. The basic endoscopic procedures performed on the simulator were esophagogastroduodenoscopy (EGD), gastric biopsy (GB), and gastric foreign body removal (FBR). Construct validity was assessed by comparing the performance of novices (final-year veterinary students and recent graduates without endoscopic experience, n=30) versus experienced subjects (doctors in veterinary medicine who had performed more than 50 clinical upper gastrointestinal endoscopic procedures as a surgeon, n=15). Tasks were scored based on completion time, and specific rating scales were developed to assess performance. Internal consistency and inter-rater agreement were assessed. Face and content validity were determined using a 5-point Likert-type scale questionnaire. The novices needed considerably more time than the experts to perform EGD, GB, and FBR, and their performance scores were significantly lower (pinternal validity of the rating scales were good. Face validity was excellent, and both groups agreed that the endoscopy scenarios were very realistic. The experts highly valued the usefulness of Simuldog for veterinary training and as a tool for assessing endoscopic skills. Simuldog is the first validated model specifically developed to be used as a training tool for endoscopy techniques in small animals.

    The paper describes a process that was developed for comparing the primary orbital dynamics behavior between space systems distributed simulations. This process is used to characterize and understand the fundamental fidelities and compatibilities of the modeling of orbital dynamics between spacecraft simulations. This is required for high-latency distributed simulations such as NASA s Integrated Mission Simulation and must be understood when reporting results from simulation executions. This paper presents 10 principal comparison tests along with their rationale and examples of the results. The Integrated Mission Simulation (IMSim) (formerly know as the Distributed Space Exploration Simulation (DSES)) is a NASA research and development project focusing on the technologies and processes that are related to the collaborative simulation of complex space systems involved in the exploration of our solar system. Currently, the NASA centers that are actively participating in the IMSim project are the Ames Research Center, the Jet Propulsion Laboratory (JPL), the Johnson Space Center (JSC), the Kennedy Space Center, the Langley Research Center and the Marshall Space Flight Center. In concept, each center participating in IMSim has its own set of simulation models and environment(s). These simulation tools are used to build the various simulation products that are used for scientific investigation, engineering analysis, system design, training, planning, operations and more. Working individually, these production simulations provide important data to various NASA projects.

    Mobile emergency simulation offers innovative continuing medical educational support to regions that may lack access to such opportunities. Furthermore, satisfaction is a critical element for active learning. Together, the authors evaluated Canadian rural healthcare providers' satisfaction from high fidelity emergency simulation training using a modified motorhome as a mobile education unit (MEU). Over a 5-month period, data was collected during 14 educational sessions in nine different southern Manitoban communities. Groups of up to five rural healthcare providers managed emergency simulation cases including polytrauma, severe sepsis, and inferior myocardial infarction with right ventricular involvement, followed by a debrief. Participants anonymously completed a feedback form that contained 11 questions on a five-point Likert scale and six short-answer questions. Data from 131 respondents were analyzed, for a response rate of 75.6%. Respondents included nurses (27.5%), medical residents (26.7%), medical first responders (16.0%), and physicians (12.2%). The median response was 5 for overall quality of learning, development of clinical reasoning skills and decision-making ability, recognition of patient deterioration, and self-reflection. The post-simulation debrief median response was also 5 for summarizing important issues, constructive criticism, and feedback to learn. Respondents also reported that the MEU provided a believable working environment (87.0%, n=114), they had limited or no previous access to high fidelity mannequins (82.7%, n=107), and they had no specific training in crisis resource management or were unfamiliar with the term (92%, n=118). A high level of satisfaction was reported in rural health providers with mobile emergency simulation. Access to and experience with high fidelity mannequins was limited, suggesting areas for potential educational growth.

    Patients with a central scotoma usually use a preferred retinal locus (PRL) consistently in daily activities. The selection process and time course of the PRL development are not well understood. We used a gaze-contingent display to simulate an isotropic central scotoma in normal subjects while they were practicing a difficult visual search task. As compared to foveal search, initial exposure to the simulated scotoma resulted in prolonged search reaction time, many more fixations and unorganized eye movements during search. By the end of a 1782-trial training with the simulated scotoma, the search performance improved to within 25% of normal foveal search. Accompanying the performance improvement, there were also fewer fixations, fewer repeated fixations in the same area of the search stimulus and a clear tendency of using one area near the border of the scotoma to identify the search target. The results were discussed in relation to natural development of PRL in central scotoma patients and potential visual training protocols to facilitate PRL development. Published by Elsevier Ltd.

    Training providers appropriately, particularly early in their caregiving careers, is an important aspect of electronic medical record (EMR) implementation. Considerable time and resources are needed to bring the newly hired providers 'up to speed' with the actual use practices of the organization. Similarly, universities lose valuable clinical training hours when students are required to spend those hours learning organization-specific EMR systems in order to participate in care during clinical rotations. Although there are multiple real-world barriers to university/health care organization training partnerships, the investment these entities share in training care providers, specifically nurses, to use and understand EMR technology encourages a question: What would be the cumulative effect of integrating a mutually agreed upon EMR system training program in to nursing classroom training on downstream hospital costs in terms of hours of direct caregiving lost, and benefits in terms of number of overall EMR trained nurses hired? In order to inform the development of a large scale study, we employed a dynamic systems modeling approach to simulate the theoretical relationships between key model variables and determine the possible effect of integrating EMR training into nursing classrooms on hospital outcomes. The analysis indicated that integrating EMR training into the nursing classroom curriculum results in more available time for nurse bedside care. Also, the simulation suggests that efficiency of clinical training can be potentially improved by centralizing EMR training within the nursing curriculum.

    To establish the effect of self-directed virtual reality (VR) simulation training on cadaveric dissection training performance in mastoidectomy and the transferability of skills acquired in VR simulation training to the cadaveric dissection training setting. Prospective study. Two cohorts of 20 novice otorhinolaryngology residents received either self-directed VR simulation training before cadaveric dissection training or vice versa. Cadaveric and VR simulation performances were assessed using final-product analysis with three blinded expert raters. The group receiving VR simulation training before cadaveric dissection had a mean final-product score of 14.9 (95 % confidence interval [CI] [12.9-16.9]) compared with 9.8 (95% CI [8.4-11.1]) in the group not receiving VR simulation training before cadaveric dissection. This 52% increase in performance was statistically significantly (P performance (P = 0.22). Two hours of self-directed VR simulation training was effective in increasing cadaveric dissection mastoidectomy performance and suggests that mastoidectomy skills are transferable from VR simulation to the traditional dissection setting. Virtual reality simulation training can therefore be employed to optimize training, and can spare the use of donated material and instructional resources for more advanced training after basic competencies have been acquired in the VR simulation environment.

  2. Use of control room simulators for training of nuclear power plant personnel

    International Nuclear Information System (INIS)

    2004-09-01

    Safety analysis and operational experience consistently indicate that human error is the greatest contributor to the risk of a severe accident in a nuclear power plant. Subsequent to the Three Mile Island accident, major changes were made internationally in reducing the potential for human error through improved procedures, information presentation, and training of operators. The use of full scope simulators in the training of operators is an essential element of these efforts to reduce human error. The operators today spend a large fraction of their time training and retraining on the simulator. As indicated in the IAEA Safety Guide on Recruitment, Qualification and Training of Personnel for Nuclear Power Plants, NS-G-2.8, 2002, representative simulator facilities should be used for training of control room operators and shift supervisors. Simulator training should incorporate normal, abnormal and accident conditions. The ability of the simulator to closely represent the actual conditions and environment that would be experienced in a real situation is critical to the value of the training received. The objective of this report is to provide nuclear power plant (NPP) managers, training centre managers and personnel involved with control room simulator training with practical information they can use to improve the performance of their personnel. While the emphasis in this publication is on simulator training of control room personnel using full scope simulators, information is also provided on how organizations have effectively used control room simulators for training of other NPP personnel, including simulators other than full-scope simulators

The difficulties for developing experimental ACS test is to obtain zero gravity and torque free conditions similar to the SCA operate in space. However, prototypes for control algorithms experimental verification are fundamental for space mission success. This paper presents the parameters estimation such as inertia matrix and position of mass centre of a Satellite Attitude Control System Simulator (SACSS, using algorithms based on least square regression and least square recursive methods. Simulations have shown that both methods have estimated the system parameters with small error. However, the least square recursive methods have performance more adequate for the SACSS objectives. The SACSS platform model will be used to do experimental verification of fundamental aspects of the satellite attitude dynamics and design of different attitude control algorithm.

    2017-01-01

    Full Text Available This work presents a software and hardware framework for a telerobotic surgery safety and motor skill training simulator. The aims are at providing trainees a comprehensive simulator for acquiring essential skills to perform telerobotic surgery. Existing commercial robotic surgery simulators lack features for safety training and optimal motion planning, which are critical factors in ensuring patient safety and efficiency in operation. In this work, we propose a hardware-in-the-loop simulator directly introducing these two features. The proposed simulator is built upon the Raven-II™ open source surgical robot, integrated with a physics engine and a safety hazard injection engine. Also, a Fast Marching Tree-based motion planning algorithm is used to help trainee learn the optimal instrument motion patterns. The main contributions of this work are (1 reproducing safety hazards events, related to da Vinci™ system, reported to the FDA MAUDE database, with a novel haptic feedback strategy to provide feedback to the operator when the underlying dynamics differ from the real robot’s states so that the operator will be aware and can mitigate the negative impact of the safety-critical events, and (2 using motion planner to generate semioptimal path in an interactive robotic surgery training environment.

    The cognitive load (CL) theoretical framework suggests that working memory is limited, which has implications for learning and skills acquisition. Complex learning situations such as surgical skills training can potentially induce a cognitive overload, inhibiting learning. This study aims to compare CL in traditional cadaveric dissection training and virtual reality (VR) simulation training of mastoidectomy. A prospective, crossover study. Participants performed cadaveric dissection before VR simulation of the procedure or vice versa. CL was estimated by secondary-task reaction time testing at baseline and during the procedure in both training modalities. The national Danish temporal bone course. A total of 40 novice otorhinolaryngology residents. Reaction time was increased by 20% in VR simulation training and 55% in cadaveric dissection training of mastoidectomy compared with baseline measurements. Traditional dissection training increased CL significantly more than VR simulation training (p < 0.001). VR simulation training imposed a lower CL than traditional cadaveric dissection training of mastoidectomy. Learning complex surgical skills can be a challenge for the novice and mastoidectomy skills training could potentially be optimized by employing VR simulation training first because of the lower CL. Traditional dissection training could then be used to supplement skills training after basic competencies have been acquired in the VR simulation.

    Companies are increasingly turning to computer software programs to improve and streamline the analysis o cogeneration systems. This paper introduces a computer program which originated with research at the University of Waterloo. The program can simulate and optimize any type of layout of cogeneration plant. An application of the program to a cogeneration feasibility study for a university campus is described. The Steam and Power Plant Optimization System (SAPPOS) is a PC software package which allows users to model any type of steam/power plant on a component-by-component basis. Individual energy/steam balances can be done quickly to model any scenario. A typical days per month cogeneration simulation can also be carried out to provide a detailed monthly cash flow and energy forecast. This paper reports that SAPPOS can be used for scoping, feasibility, and preliminary design work, along with financial studies, gas contract studies, and optimizing the operation of completed plants. In the feasibility study presented, SAPPOS is used to evaluate both diesel engine and gas turbine combined cycle options

  16. Simulation and sequential dynamical systems

    Energy Technology Data Exchange (ETDEWEB)

    Mortveit, H.S.; Reidys, C.M.

    1999-06-01

    Computer simulations have a generic structure. Motivated by this the authors present a new class of discrete dynamical systems that captures this structure in a mathematically precise way. This class of systems consists of (1) a loopfree graph {Upsilon} with vertex set {l_brace}1,2,{hor_ellipsis},n{r_brace} where each vertex has a binary state, (2) a vertex labeled set of functions (F{sub i,{Upsilon}}:F{sub 2}{sup n} {yields} F{sub 2}{sup n}){sub i} and (3) a permutation {pi} {element_of} S{sub n}. The function F{sub i,{Upsilon}} updates the state of vertex i as a function of the states of vertex i and its {Upsilon}-neighbors and leaves the states of all other vertices fixed. The permutation {pi} represents the update ordering, i.e., the order in which the functions F{sub i,{Upsilon}} are applied. By composing the functions F{sub i,{Upsilon}} in the order given by {pi} one obtains the dynamical system (equation given in paper), which the authors refer to as a sequential dynamical system, or SDS for short. The authors will present bounds for the number of functionally different systems and for the number of nonisomorphic digraphs {Gamma}[F{sub {Upsilon}},{pi}] that can be obtained by varying the update order and applications of these to specific graphs and graph classes.

    2014-09-01

    An initial research indicated that realistic haptic simulators with an adapted training concept are needed to enhance the training for spinal surgery. A cognitive task analysis (CTA) was performed to define a realistic and helpful scenario-based simulation. Based on the results a simulator for lumbar discectomy was developed. Additionally, a realistic training operating room was built for a pilot. The results were validated. The CTA showed a need for realistic scenario-based training in spine surgery. The developed simulator consists of synthetic bone structures, synthetic soft tissue and an advanced bleeding system. Due to the close interdisciplinary cooperation of surgeons between engineers and psychologists, the iterative multicentre validation showed that the simulator is visually and haptically realistic. The simulator offers integrated sensors for the evaluation of the traction being used and the compression during surgery. The participating surgeons in the pilot workshop rated the simulator and the training concept as very useful for the improvement of their surgical skills. In the context of the present work a precise definition for the simulator and training concept was developed. The additional implementation of sensors allows the objective evaluation of the surgical training by the trainer. Compared to other training simulators and concepts, the high degree of objectivity strengthens the acceptance of the feedback. The measured data of the nerve root tension and the compression of the dura can be used for intraoperative control and a detailed postoperative evaluation.

    Shepanski, J. F.; Macy, S. A.

    1987-01-01

    A methodology was developed for manually training autonomous control systems based on artificial neural systems (ANS). In applications where the rule set governing an expert's decisions is difficult to formulate, ANS can be used to extract rules by associating the information an expert receives with the actions taken. Properly constructed networks imitate rules of behavior that permits them to function autonomously when they are trained on the spanning set of possible situations. This training can be provided manually, either under the direct supervision of a system trainer, or indirectly using a background mode where the networks assimilates training data as the expert performs its day-to-day tasks. To demonstrate these methods, an ANS network was trained to drive a vehicle through simulated freeway traffic.

    2016-01-01

    Full Text Available This paper investigates the dynamic response of a train-bridge system subjected to earthquakes, and the running safety indices of the train on the bridge under earthquake are studied. Taking a long span cable-stayed bridge across the Huangpu River as an example, a full three-dimensional finite element model of the train-bridge system was established, in which the soil-bridge and rail-train interactions were considered. Parallel computing based on contact balance was utilized to deal with this large-scale numerical simulation problem. The dynamic nonlinear analysis was performed on a Hummingbird supercomputer using the finite element code LS-DYNA 971. The results show that the acceleration responses of the train subjected to an earthquake are much greater than the ones without earthquake input, and the running safety of a moving train is affected by both the earthquake intensity and the running speed of the train. The running safety of the moving train can be evaluated by the threshold curve between earthquake intensity and train speed. The proposed modeling strategies and the simulated results can give a reference prediction of the dynamic behaviour of the train-bridge subjected to an earthquake.

    Ever since the earliest days of the Magnox stations with training programs which were first run in the late 1950s, use has been made of simulation devices. In those early days of nuclear power, analog techniques were used to develop an understanding of reactor dynamics. The value of this type of limited scope device for training in basic principles has been confirmed over the years. The analog simulator - in use for over 20 years -has just been replaced by a microprocessor driven unit with extended scope to include a heat exchanger unit (thus completing the primary circuit). A wider range of faults have been incorporated together with tutor facilities and display systems which have taken advantage of today's technologies. The modelling software and the use of an interchangeable panel enable it to represent either a Magnox or an AGR system

    2015-12-01

    This paper evaluates cloud resolving model (CRM) and cloud system-resolving model (CSRM) simulations of a midlatitude cirrus case with comprehensive observations collected under the auspices of the Atmospheric Radiation Measurements (ARM) program and with spaceborne observations from the National Aeronautics and Space Administration (NASA) A-train satellites. Vertical profiles of temperature, relative humidity and wind speeds are reasonably well simulated by the CSRM and CRM but there are remaining biases in the temperature, wind speeds and relative humidity, which can be mitigated through nudging the model simulations toward the observed radiosonde profiles. Simulated vertical velocities are underestimated in all simulations except in the CRM simulations with grid spacings of 500m or finer, which suggests that turbulent vertical air motions in cirrus clouds need to be parameterized in GCMs and in CSRM simulations with horizontal grid spacings on the order of 1km. The simulated ice water content and ice number concentrations agree with the observations in the CSRM but are underestimated in the CRM simulations. The underestimation of ice number concentrations is consistent with the overestimation of radar reflectivity in the CRM simulations and suggests that the model produces too many large ice particles especially toward cloud base. Simulated cloud profiles are rather insensitive to perturbations in the initial conditions or the dimensionality of the model domain but the treatment of the forcing data has a considerable effect on the outcome of the model simulations. Despite considerable progress in observations and microphysical parameterizations, simulating the microphysical, macrophysical and radiative properties of cirrus remains challenging. Comparing model simulations with observations from multiple instruments and observational platforms is important for revealing model deficiencies and for providing rigorous benchmarks. However, there still is considerable

    High fidelity simulation allows training of foundation doctors in a safe, structured environment. We explored the perceived impact of such training on subsequent clinical practice. 82 doctors attended and 52% responded to a follow up questionnaire sent two months after their training. 88% felt better able to manage the acutely ill patient than they did before their training. All cited simulation training as a reason for this and 44% felt simulation training was the main contributor. The remainder cited clinical experience as the main contributor. 53% gave real clinical examples where they applied skills attributed to simulation training. Doctors reflected positively on simulation training sometime after the experience, demonstrated transference of learnt skills and felt more confident at work.

    2013-10-01

    Full Text Available For decades the issue of training through simulation has been discussed and studied to show its value and importance in fighter pilot training programs. Besides the fact that simulators are less expensive than a real airplane, and eliminate the operational risks that are present in a real flight they bring a significant contribution to the pilot training by their fidelity and realism that they show in such scenarios as in the reality. To measure the efficiency of training transfer from simulator to the aircraft, performance indicators were defined. The purpose of this article is to define these performance indicators and measurement of training transfer within the flight simulator involvement.

    This paper is written to introduce a multimedia tutoring system for nondestructive testing using personal computer. Nondestructive testing, one of the chief methods for inspecting welds and many other components, is very difficult for the NDT inspectors to understand its technical basis without a wide experience. And it is necessary for considerable repeated education and training for keeping their knowledge. The tutoring system that can simulate NDT works is suggested to solve the above problem based on reasonable condition. The tutoring system shows basic theories of nondestructive testing in a book-style with video images and hyper-links, and it offers practices, in which users can simulate the testing equipment. The book-style and simulation practices provide effective and individual environments for learning nondestructive testing

Afterwards, we proposed a new process using Colored Petri Nets to verify the TTDMS system functional safety, as well as to evaluate the system performance. Three main contributions are carried out in the paper: Firstly, this paper proposes a formalized TTDMS model, and the model correctness is validated using state space analysis and simulation-based verification. Secondly, corresponding checking queries are proposed for the purpose of functional safety verification. Further, the TTDMS performance is evaluated by applying parameters in the formal model. Thirdly, the reliability of a functional prototype TTDMS is estimated. It is found that the procedure can cooperate with the system development, and both formal and simulation-based verifications are performed. Using our process to evaluate and verify a system is easier to read and more reliable compared to executable code and mathematical methods. - Highlights: • A new Train to Train Distance Measurement System. • New approach verifying system functional safety and evaluating system performance by means of CPN. • System formalization using the system property concept. • Verification of system functional safety using state space analysis. • Evaluation of system performance applying simulation-based analysis.

    This paper briefly reviews challenges to psychoanalysis at this time, including those derived from both external, societal origins and internal psychoanalytic problems. It focuses attention on serious conflicts around psychoanalytic education, and refers to the training analysis system as a central problem determining fundamental constraints on present-day psychoanalytic education. These constraints are examined in some detail, and the general advantages and disadvantages of the training analysis system are outlined. The effects of all these dynamics on the administrative organization of the American Psychoanalytic Association are explored, and a proposal for a fundamental reorganization of our educational system to resolve the correspondent problems is outlined.

    Training offsite emergency response personnel basic awareness of onsite control room operations during nuclear power plant emergency conditions was the primary objective of a week-long workshop conducted on a CANDU® virtual nuclear reactor simulator available at the University of Ontario Institute of Technology, Oshawa, Canada. The workshop was designed to examine both normal and abnormal reactor operating conditions, and to observe the conditions in the control room that may have impact on the subsequent offsite emergency response. The workshop was attended by participants from a number of countries encompassing diverse job functions related to nuclear emergency response. Objectives of the workshop were to provide opportunities for participants to act in the roles of control room personnel under different reactor operating scenarios, providing a unique experience for participants to interact with the simulator in real-time, and providing increased awareness of control room operations during accident conditions. The ability to "pause" the simulator during exercises allowed the instructors to evaluate and critique the performance of participants, and to provide context with respect to potential offsite emergency actions. Feedback from the participants highlighted (i) advantages of observing and participating "hands-on" with operational exercises, (ii) their general unfamiliarity with control room operational procedures and arrangements prior to the workshop, (iii) awareness of the vast quantity of detailed control room procedures for both normal and transient conditions, and (iv) appreciation of the increased workload for the operators in the control room during a transient from normal operations. Based upon participant feedback, it was determined that the objectives of the training had been met, and that future workshops should be conducted.

    A JOYO full scope operator training simulator installed in 1983, is being used with high average unit availability factor of more than 70% per annum. The education and training for the operators using it has been greatly contributing to safety operation of the experimental fast reactor JOYO. The simulator mainly consisting of five control panels, a computer system having two computers and an instructor's console, is able to simulate the plant behaviors and the sequential processes with real time under normal or anomaly conditions. Now, according as the JOYO MK-ILL project which enhances the irradiation capability of JOYO, an upgrading program of the simulator is proceeding with the aim of advancing its efficient usage by improving the training function and the analytical accuracy of the simulator.

    Based on the discrete time method, an effective movement control model is designed for a group of highspeed trains on a rail network. The purpose of the model is to investigate the specific traffic characteristics of high-speed trains under the interruption of stochastic irregular events. In the model, the high-speed rail traffic system is supposed to be equipped with the moving-block signalling system to guarantee maximum traversing capacity of the railway. To keep the safety of trains' movements, some operational strategies are proposed to control the movements of trains in the model, including traction operation, braking operation, and entering-station operation. The numerical simulations show that the designed model can well describe the movements of high-speed trains on the rail network. The research results can provide the useful information not only for investigating the propagation features of relevant delays under the irregular disturbance but also for rerouting and rescheduling trains on the rail network.

    Care of the trauma patient requires a well-coordinated intensive effort during the golden hour to optimize survival. We hypothesized that this program would improve knowledge, satisfaction, self-confidence, and simulated team performance. A pre-, post-test design with N = 7 BSN nurses, 21 years of age, less than 2 years of intensive care unit and nursing experience. Trauma intensive care unit, single-center academic Level 1 trauma center. Improvement was shown in perception of team structure (paired t test 13.71-12.57; p = .0001) and communication (paired t test 14.85-12.14; p = .009). Improvement was shown in observed situation monitoring (paired t test 17.42-25.28; p = .000), mutual support (paired t test 12.57-18.57; p = .000), and communication (paired t test 15.42-25.00; p = .001). A decrease was shown in attitudes of mutual support (paired t test 25.85-19.71; p = .04) and communication (paired t test 26.14-23.00; p = .001). Mean satisfaction scores were 21.5 of a possible 25 points. Mean self-confidence scores were 38.83 out of a possible 40 points. Simulation-based team training improved teamwork attitudes, perceptions, and performance. Team communication demonstrated significant improvement in 2 of the 3 instruments. Most participants agreed or strongly agreed that they were satisfied with simulation and had gained self-confidence.

    This exploratory study initiated our research into the software infrastructure necessary to support the modeling and simulation techniques that are most appropriate for the Information Power Grid. Such computational power grids will use high-performance networking to connect hardware, software, instruments, databases, and people into a seamless web that supports a new generation of computation-rich problem solving environments for scientists and engineers. In this context we looked at evaluating the NetSolve software environment for network computing that leverages the potential of such systems while addressing their complexities. NetSolve's main purpose is to enable the creation of complex applications that harness the immense power of the grid, yet are simple to use and easy to deploy. NetSolve uses a modular, client-agent-server architecture to create a system that is very easy to use. Moreover, it is designed to be highly composable in that it readily permits new resources to be added by anyone willing to do so. In these respects NetSolve is to the Grid what the World Wide Web is to the Internet. But like the Web, the design that makes these wonderful features possible can also impose significant limitations on the performance and robustness of a NetSolve system. This project explored the design innovations that push the performance and robustness of the NetSolve paradigm as far as possible without sacrificing the Web-like ease of use and composability that make it so powerful.

    We hypothesized that novices will perform better in the operating room after simulator training to automaticity compared with traditional proficiency based training (current standard training paradigm). Simulator-acquired skill translates to the operating room, but the skill transfer is incomplete. Secondary task metrics reflect the ability of trainees to multitask (automaticity) and may improve performance assessment on simulators and skill transfer by indicating when learning is complete. Novices (N = 30) were enrolled in an IRB-approved, blinded, randomized, controlled trial. Participants were randomized into an intervention (n = 20) and a control (n = 10) group. The intervention group practiced on the FLS suturing task until they achieved expert levels of time and errors (proficiency), were tested on a live porcine fundoplication model, continued simulator training until they achieved expert levels on a visual spatial secondary task (automaticity) and were retested on the operating room (OR) model. The control group participated only during testing sessions. Performance scores were compared within and between groups during testing sessions. : Intervention group participants achieved proficiency after 54 ± 14 and automaticity after additional 109 ± 57 repetitions. Participants achieved better scores in the OR after automaticity training [345 (range, 0-537)] compared with after proficiency-based training [220 (range, 0-452; P training to automaticity takes more time but is superior to proficiency-based training, as it leads to improved skill acquisition and transfer. Secondary task metrics that reflect trainee automaticity should be implemented during simulator training to improve learning and skill transfer.

  17. Kinematic Skeleton Based Control of a Virtual Simulator for Military Training

    2015-06-01

    Full Text Available Virtual simulation technology has been considered as a highly efficient and cost-effective solution for a soldier training system, and evolved into diverse combinations of hardware and software. To maximize the virtual reality effect within a restricted space, a locomotion interface such as an omni-directional treadmill is introduced as a major component of a virtual simulator, therefore real time interaction between human and the virtual simulator becomes very important. Displacement and heading changes of the trainee are crucial information to control the virtual simulator when we implement highly reactive motion control for the omni-directional treadmill and interaction control of the virtual contents. This paper proposes a control parameter estimation algorithm for the virtual training simulator by using two types of motion capture sensors and presents the experimental results. Kinematic joint positions are analyzed to estimate the trainee’s location and velocity for feedback and feedforward control of the omni-directional treadmill. The accuracy of two approaches is evaluated by comparing with the reference system, which gives a ground truth value.

    2011-01-01

    In this presentation, we highlight the deployment of a real-time dynamic simulator of an integrated gasification combined cycle (IGCC) power plant with CO{sub 2} capture at the Department of Energy's (DOE) National Energy Technology Laboratory's (NETL) Advanced Virtual Energy Simulation Training and Research (AVESTARTM) Center. The Center was established as part of the DOE's accelerating initiative to advance new clean coal technology for power generation. IGCC systems are an attractive technology option, generating low-cost electricity by converting coal and/or other fuels into a clean synthesis gas mixture in a process that is efficient and environmentally superior to conventional power plants. The IGCC dynamic simulator builds on, and reaches beyond, conventional power plant simulators to merge, for the first time, a 'gasification with CO{sub 2} capture' process simulator with a 'combined-cycle' power simulator. Fueled with coal, petroleum coke, and/or biomass, the gasification island of the simulated IGCC plant consists of two oxygen-blown, downward-fired, entrained-flow, slagging gasifiers with radiant syngas coolers and two-stage sour shift reactors, followed by a dual-stage acid gas removal process for CO{sub 2} capture. The combined cycle island consists of two F-class gas turbines, steam turbine, and a heat recovery steam generator with three-pressure levels. The dynamic simulator can be used for normal base-load operation, as well as plant start-up and shut down. The real-time dynamic simulator also responds satisfactorily to process disturbances, feedstock blending and switchovers, fluctuations in ambient conditions, and power demand load shedding. In addition, the full-scope simulator handles a wide range of abnormal situations, including equipment malfunctions and failures, together with changes initiated through actions from plant field operators. By providing a comprehensive IGCC operator training system, the

    Full Text Available Background: Modern medical education promotes medical students’ clinical operating capacity rather than the mastery of theoretical knowledge. To accomplish this objective, clinical skill training using various simulations was introduced into medical education to cultivate creativity and develop the practical ability of students. However, quantitative analysis of the efficiency of clinical skill training with simulations is lacking. Methods: In the present study, we compared the mean scores of medical students (Jinan University who graduated in 2013 and 2014 on 16 stations between traditional training (control and simulative training groups. In addition, in a clinical skill competition, the objective structured clinical examination (OSCE scores of participating medical students trained using traditional and simulative training were compared. The data were statistically analyzed and qualitatively described. Results: The results revealed that simulative training could significantly enhance the graduate score of medical students compared with the control. The OSCE scores of participating medical students in the clinical skill competition, trained using simulations, were dramatically higher than those of students trained through traditional methods, and we also observed that the OSCE marks were significantly increased for the same participant after simulative training for the clinical skill competition. Conclusions: Taken together, these data indicate that clinical skill training with a variety of simulations could substantially promote the clinical performance of medical students and optimize the resources used for medical education, although a precise analysis of each specialization is needed in the future.

    To develop a non-biological 3D printed simulator for training and preoperative planning in percutaneous nephrolithotripsy (PCNL), which allows doctors to master and perform all stages of the operation under ultrasound and fluoroscopy guidance. The 3D model was constructed using multislice spiral computed tomography (MSCT) images of a patient with staghorn urolithiasis. The MSCT data were processed and used to print the model. The simulator consisted of two parts: a non-biological 3D printed soft model of a kidney with reproduced intra-renal vascular and collecting systems and a printed 3D model of a human body. Using this 3D printed simulator, PCNL was performed in the interventional radiology operating room under ultrasound and fluoroscopy guidance. The designed 3D printed model of the kidney completely reproduces the individual features of the intra-renal structures of the particular patient. During the training, all the main stages of PCNL were performed successfully: the puncture, dilation of the nephrostomy tract, endoscopic examination, intra-renal lithotripsy. Our proprietary 3D-printed simulator is a promising development in the field of endourologic training and preoperative planning in the treatment of complicated forms of urolithiasis.

    Full Text Available Background: Age-related cognitive decline is often associated with unsafe driving behavior. We hypothesized that 10 active training sessions in a driving simulator increase cognitive and on-road driving performance. In addition, driving simulator training should outperform cognitive training.Methods: Ninety-one healthy active drivers (62 – 87 years were randomly assigned to either (1 a driving simulator training group, (2 an attention training group (vigilance and selective attention, or (3 a control group. The main outcome variables were on-road driving and cognitive performance. Seventy-seven participants (85% completed the training and were included in the analyses. Training gains were analyzed using a multiple regression analysis with planned comparisons.Results: The driving simulator training group showed an improvement in on-road driving performance compared to the attention training group. In addition, both training groups increased cognitive performance compared to the control group. Conclusion: Driving simulator training offers the potential to enhance driving skills in older drivers. Compared to the attention training, the simulator training seems to be a more powerful program for increasing older drivers’ safety on the road.

    A computer program to simulate hybrid and electric advanced vehicle systems (HEAVY) is described. It is intended for use early in the design process: concept evaluation, alternative comparison, preliminary design, control and management strategy development, component sizing, and sensitivity studies. It allows the designer to quickly, conveniently, and economically predict the performance of a proposed drive train. The user defines the system to be simulated using a library of predefined component models that may be connected to represent a wide variety of propulsion systems. The development of three models are discussed as examples.

    2016-02-01

    This review presents current virtual reality based training simulators for hip, knee and other orthopaedic surgery, including elective and trauma surgical procedures. There have not been any reviews focussing on hip and knee orthopaedic simulators. A comparison of existing simulator features is provided to identify what is missing and what is required to improve upon current simulators. In total 11 hip replacements pre-operative planning tools were analysed, plus 9 hip trauma fracture training simulators. Additionally 9 knee arthroscopy simulators and 8 other orthopaedic simulators were included for comparison. The findings are that for orthopaedic surgery simulators in general, there is increasing use of patient-specific virtual models which reduce the learning curve. Modelling is also being used for patient-specific implant design and manufacture. Simulators are being increasingly validated for assessment as well as training. There are very few training simulators available for hip replacement, yet more advanced virtual reality is being used for other procedures such as hip trauma and drilling. Training simulators for hip replacement and orthopaedic surgery in general lag behind other surgical procedures for which virtual reality has become more common. Further developments are required to bring hip replacement training simulation up to date with other procedures. This suggests there is a gap in the market for a new high fidelity hip replacement and resurfacing training simulator. Copyright © 2015 IPEM. Published by Elsevier Ltd. All rights reserved.

    Laparoscopic virtual reality simulators are becoming a ubiquitous tool in resident training and assessment. These devices provide the operator with various levels of realism, including haptic (or force) feedback. However, this feature adds significantly to the cost of the devices, and limited data exist assessing the value of haptics in skill acquisition and development. Utilizing the Laparoscopy VR (Immersion Medical, Gaithersburg, MD), we hypothesized that the incorporation of force feedback in the simulated operative environment would allow superior trainee performance compared with performance of the same basic skills tasks in a non-haptic model. Ten medical students with minimal laparoscopic experience and similar baseline skill levels as proven by performance of two fundamentals of laparoscopic surgery (FLS) tasks (peg transfer and cutting drills) voluntarily participated in the study. Each performed two tasks, analogous to the FLS drills, on the Laparoscopy VR at 3 levels of difficulty, based on the established settings of the manufacturer. After achieving familiarity with the device and tasks, the students completed the drills both with and without force feedback. Data on completion time, instrument path length, right and left hand errors, and grasping tension were analyzed. The scores in the haptic-enhanced simulation environment were compared with the scores in the non-haptic model and analyzed utilizing Student's t-test. The peg transfer drill showed no difference in performance between the haptic and non-haptic simulations for all metrics at all three levels of difficulty. For the more complex cutting exercise, the time to complete the tasks was significantly shorter when force feedback was provided, at all levels of difficulty (158+/-56 versus 187+/-51 s, 176+/-49 versus 222+/-68 s, and 275+/-76 versus 422+/-220 s, at levels 1, 2, and 3, respectively, Psimulation did not demonstrate an appreciable performance improvement among our trainees.

    This report is based on a review of the literature published on simulator training and on discussions with representatives from the German nuclear power plant operator training schools. A brief description of the organisation and content of the simulator training of control room operators in a number of countries, together with a catagorisation of the various types of simulators which are used. The concepts of the systems approach to training and simulator fidelity are discussed. Some general training principles which are considered important for simulator training are summarised. From the available descriptions and analyses of control room operator tasks, the skills (in most general terms) which can be trained at simulators have been identified. Methods for training these skills which are used in the simulator training programmes in various industries and which have been developed in research work in the area of training psychology have been summarised. Using these methods as a basis, the necessary instructor facilities which should be included in the design of a full simulator for the Konvoi generation of nuclear power plants have been derived.

    To provide a software environment for simulation of robotic radiosurgery, particularly to study the effective robot workspace with respect to the treatment plan quality, and to illustrate the concepts of robotic radiosurgery. A simulation environment for a robotic radiosurgery system was developed using Java and Java3D. The kinematics and the beam characteristics were modeled and linked to a treatment planning module. Simulations of different robot workspace parameters for two example radiosurgical patient cases were performed using the novel software tool. The first case was an intracranial lesion near the left inner ear, the second case was a spinal lesion. The planning parameters for both cases were visualized with the novel simulation environment. An incremental extension of the robot workspace had limited effect for the intracranial case, where the original workspace already covered the left side of the patient. For the spinal case, a larger workspace resulted in a noticeable improvement in plan quality and a large portion of the beams being delivered from the extended workspace. The new software environment is useful to simulate and analyze parameters and configurations for robotic radiosurgery. An enlarged robot workspace may result in improved plan quality depending on the location of the target region. (orig.)

    Autorotation is a maneuver that permits a safe helicopter landing when the engine loses power. A catastrophe may occur if the pilot's control inputs are incorrect, insufficient, excessive, or poorly timed. Due to the danger involved, full-touchdown autorotations are very rarely practiced. Because in-flight autorotation training is risky, time-consuming, and expensive, the objective of the project was to develop the first helicopter flight simulator expressly designed to train students in this critical maneuver. A central feature of the project was the inclusion of an enhanced version of the Pilot-Rotorcraft Intelligent Symbology Management Simulator (PRISMS), a virtual-reality system developed by Anacapa Sciences and Thought Wave. A task analysis was performed to identify the procedural steps in the autorotation, to inventory the information needed to support student task performance, to identify typical errors, and to structure the simulator's practice environment. The system provides immediate knowledge of results, extensive practice of perceptual-motor skills, part-task training, and augmented cueing in a realistic cockpit environment. Additional work, described in this report, extended the capabilities of the simulator in three areas: 1. Incorporation of visual training aids to assist the student in learning the proper appearance of the visual scene when the maneuver is being properly performed; 2. Introduction of the requirement to land at a particular spot, as opposed to the wide, flat open field initially used, and development of appropriate metrics of success; and 3. Inclusion of wind speed and wind direction settings (and random variability settings) to add a more realistic challenge in "hitting the spot."

    Several IAEA guidance publications on safety culture and NPP personnel training consider the role of training and particularly the role of simulators training to enhance the safety of NPP operations. Initially, the focus has been on full-scope simulators for the training of main control room operators. Presently, a wide range of different types of simulators are used at training center. Several guidance publications concerning development and use of full-scope simulators are currently available. Experience shows that other types of simulators are also effective training tools that allow simulator training for a broader range of target groups and training objectives. Based on this need, the IAEA undertook a project to prepare a report on selection, specification, design and use of various training simulators, which provides guidance to training centers and suppliers for proper selection, specification, design, and use of various form of simulators. In addition, it provides examples of their use in several Member States. This paper presents a summary of the IAEATECDOC publication on the subject. (author)

    Full Text Available Purpose. One of the priorities of station sorting complex functioning improvement is the breaking-up process energy consumptions reduction, namely: fuel consumption for train pushing and electric energy consumption for cut braking. In this regard, an effective solution of the problem of energy consumption reduction at breaking-up subsystem requires a comprehensive handling of train pushing and cut rolling down processes. At the same time, the analysis showed that the current task of pushing process improvement and cut rolling down effectiveness increase are solved separately. To solve this problem it is necessary to develop the complex simulation model of train breaking up process at humps. Methodology. Pushing process simulation was done based on adapted under the shunting conditions traction calculations. In addition, the features of shunting locomotives work at the humps were taken into account. In order to realize the current pushing mode the special algorithm of hump locomotive controlling, which along with the safety shunting operation requirements takes into account behavioral factors associated with engineer control actions was applied. This algorithm provides train smooth acceleration and further movement with speed, which is close to the set speed. Hump locomotive fuel consumptions were determined based on the amount of mechanical work performed by locomotive traction. Findings. The simulation model of train pushing process was developed and combined with existing cut rolling down model. Cut initial velocity is determined during simulation process. The obtained initial velocity is used for further cut rolling process modeling. In addition, the modeling resulted in sufficiently accurate determination of the fuel rates consumed for train breaking-up. Originality. The simulation model of train breaking-up process at the humps, which in contrast to the existing models allows reproducing complexly all the elements of this process in detail

    To inform surgeons about the practical issues to be considered for successful integration of virtual reality simulation into a surgical training program. The learning and practice of minimally invasive surgery (MIS) makes unique demands on surgical training programs. A decade ago Satava proposed virtual reality (VR) surgical simulation as a solution for this problem. Only recently have robust scientific studies supported that vision A review of the surgical education, human-factor, and psychology literature to identify important factors which will impinge on the successful integration of VR training into a surgical training program. VR is more likely to be successful if it is systematically integrated into a well-thought-out education and training program which objectively assesses technical skills improvement proximate to the learning experience. Validated performance metrics should be relevant to the surgical task being trained but in general will require trainees to reach an objectively determined proficiency criterion, based on tightly defined metrics and perform at this level consistently. VR training is more likely to be successful if the training schedule takes place on an interval basis rather than massed into a short period of extensive practice. High-fidelity VR simulations will confer the greatest skills transfer to the in vivo surgical situation, but less expensive VR trainers will also lead to considerably improved skills generalizations. VR for improved performance of MIS is now a reality. However, VR is only a training tool that must be thoughtfully introduced into a surgical training curriculum for it to successfully improve surgical technical skills.

    To compare the effect of simulator functional fidelity (manikin vs a Dynamic Haptic Robotic Trainer [DHRT]) and personalized feedback on surgical resident self-efficacy and self-ratings of performance during ultrasound-guided internal jugular central venous catheterization (IJ CVC) training. In addition, we seek to explore how self-ratings of performance compare to objective performance scores generated by the DHRT system. Participants were randomly assigned to either manikin or DHRT IJ CVC training over a 6-month period. Self-efficacy surveys were distributed before and following training. Training consisted of a pretest, 22 practice IJ CVC needle insertion attempts, 2 full-line practice attempts, and a posttest. Participants provided self-ratings of performance for each needle insertion and were presented with feedback from either an upper level resident (manikin) or a personalized learning system (DHRT). A study was conducted from July 2016 to February 2017 through a surgical skills training program at Hershey Medical Center in Hershey, Pennsylvania. Twenty-six first-year surgical residents were recruited for the study. Individuals were informed that IJ CVC training procedures would be consistent regardless of participation in the study and that participation was optional. All recruited residents opted to participate in the study. Residents in both groups significantly improved their self-efficacy scores from pretest to posttest (p training with the DHRT system and the personalized learning feedback can improve resident self-efficacy with IJ CVC procedures and provide sufficient feedback to allow residents to accurately assess their own performance.

    Operators of Hamaoka Nuclear Power Station in the past received training at BWR Operator Training Center Corporation, which is a professional operator training institution. Since completion of a full-scope simulator that models Hamaoka unit 3 on the premises of the site in April 1993, Chubu Electric Power Company has been providing initial training and continuing training for operators by original training programs. The initial training for operators consists of on-the-job training, simulator training, and classroom training aiming to train full-fledged operators in four years. The continuing training for operators, which is classified into refresher training courses for trainees with equal operating skill and family training courses for a shift team, makes training effective to each objectives progressing and maintaining operating skill, or fostering teamwork. Besides the above, the simulator is utilized in full scale exercises for radiological emergencies and specialized training for technical staff other than operators. In addition, it is used for public acceptance of nuclear power in ''First-hand Experience Course,'' which is set for nuclear public relations personnel in the company, local people, and the press. Furthermore, it is widely used in a seminar for exchange among universities, manufacturers, and the company

    2011-01-01

    Background Simulation-based medical education has been widely used in medical skills training; however, the effectiveness and long-term outcome of simulation-based training in thoracentesis requires further investigation. The purpose of this study was to assess the learning curve of simulation-based thoracentesis training, study skills retention and transfer of knowledge to a clinical setting following simulation-based education intervention in thoracentesis procedures. Methods Fifty-two medical students were enrolled in this study. Each participant performed five supervised trials on the simulator. Participant's performance was assessed by performance score (PS), procedure time (PT), and participant's confidence (PC). Learning curves for each variable were generated. Long-term outcome of the training was measured by the retesting and clinical performance evaluation 6 months and 1 year, respectively, after initial training on the simulator. Results Significant improvements in PS, PT, and PC were noted among the first 3 to 4 test trials (p 0.05). Clinical competency in thoracentesis was improved in participants who received simulation training relative to that of first year medical residents without such experience (p simulation-based thoracentesis training can significantly improve an individual's performance. The saturation of learning from the simulator can be achieved after four practice sessions. Simulation-based training can assist in long-term retention of skills and can be partially transferred to clinical practice. PMID:21696584

    Cast application and removal are essential to orthopedics and performed by providers of variable training. Simulation training and practice of proper cast application and removal may reduce injury, optimize outcomes, and reduce health care costs. The purpose of this educational initiative was to develop, validate, and implement a novel simulation trainer and curriculum to improve safety during cast removal. In all, 30 thermocouples (Omega, Stamford, CT) were applied to a radius fracture model (Sawbones, Vashon, WA). After reduction and cast application, a saw (Stryker, Kalamazoo, MI) was used to cut the cast with temperature recording. Both "good" and "poor" techniques-as established by consensus best practices-were used. Maximal temperatures were compared to known thresholds for thermal injury; humans experience pain at temperatures exceeding 47°C and contact temperatures exceeding 60°C may lead to epidermal necrosis. Construct validity was evaluated by assessing novice (postgraduate year 1), intermediate (postgraduate year 3), and expert (pediatric orthopedic attending) performance. With the "good" technique, mean peak temperatures were 43°C + 4.3°C. The highest recorded was 51.9°C. With the "poor" technique, mean peak temperature was 75.2°C + 17.3°C. The maximum temperature recorded with the "poor" technique was 112.4°C. Construct validity testing showed that novices had the highest increases in temperatures (12.9°C). There was a decline in heat generation as experience increased with the intermediate group (9.7°C), and the lowest heat generation was seen in the expert group (5.0°C). A novel task simulator and curriculum have been developed to assess competency and enhance performance in the application and removal of casts. There was a 32.2°C temperature decrease when the proper cast saw technique was used. Furthermore, the "poor" technique consistently achieved temperatures that would cause epidermal necrosis in patients. Clinical experience was a

    2015-01-01

    Full Text Available Considering the issues of lower limb rehabilitation robots with single control strategies and poor training types, a training method for improving muscle strength was put forward in this paper. Patients’ muscle strength could be achieved by targeted exercises at the end of rehabilitation. This approach could be realized through programming wires’ force. On the one hand, each wires force was measured by tension sensor and force closed loop control was established to control the value of wires’ force which was acted on trainees. On the other hand, the direction of output force was changed by detecting the trainees’ state of motion and the way of putting load to patient was achieved. Finally, the target of enhancing patients’ muscle strength was realized. Dynamic model was built by means of mechanism and training types of robots. Force closed loop control strategy was established based on training pattern. In view of the characteristics of the redundance and economy of wire control, the process for simple wire's load changes was discussed. In order to confirm the characteristics of robot control system, the controller was simulated in Matlab/Simulink. It was verified that command signal could be traced by control system availably and the load during muscle training would be provided effectively.

    Crews who inhabit spacecraft with complex 3D architecture frequently report inflight disorientation and navigation problems. Preflight virtual reality (VR) training may reduce those risks. Although immersive VR techniques may better support spatial orientation training in a local environment, a non-immersive desktop (DT) system may be more convenient for navigation training in "building scale" spaces, especially if the two methods achieve comparable results. In this study trainees' orientation and navigation performance during simulated space station emergency egress tasks was compared while using immersive head-mounted display (HMD) and DT-VR systems. Analyses showed no differences in pointing angular-error or egress time among the groups. The HMD group was significantly faster than DT group when pointing from destination to start location and from start toward different destination. However, this may be attributed to differences in the input device used (a head-tracker for HMD group vs. a keyboard touchpad or a gamepad in the DT group). All other 3D navigation performance measures were similar using the immersive and non-immersive VR systems, suggesting that the simpler desktop VR system may be useful for astronaut 3D navigation training.

  17. Employability: Challenges for Education and Training Systems

    Science.gov (United States)

    Perez, Elena Arjona; Garrouste, Christelle; Kozovska, Kornelia

    The recent crisis has taken its toll in terms of unemployment, especially among young people. This has revived the debate on the contribution of Education and Training (E&T) systems to the employability of young graduates. At European policy level, there is a growing interest in creating incentives for reforming E&T systems so as to make them more responsive to future labour market needs and short term adverse labour market conditions. One of the main challenges is finding valid measures for evaluating the contribution of E&T systems to employability, taking into account their diversity within the European Union. This paper presents an operational framework of analysis for employability and discusses some of the most important challenges related to the multidimensional nature of the employability concept, the lack of data for cross-country comparison and the difficulty of disentangling the role of education and training systems from other factors in evaluating labour market outcomes.

    Advances in virtual endoscopy simulators have paralleled an interest in medical simulation for gastrointestinal endoscopy training. The primary objective was to determine whether the virtual endoscopy simulator training could improve the performance of novices. A systematic review. Randomized controlled trials (RCTs) that compared virtual endoscopy simulator training with bedside teaching or any other intervention for novices were collected. Novice endoscopists. The PRISMA statement was followed during the course of the research. The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and ScienceDirect were searched (up to July 2013). Data extraction and assessment were independently performed. Independent procedure completion, total procedure time and required assistance. Fifteen studies (n = 354) were eligible for inclusion: 9 studies designed for colonoscopy training, 6 for gastroscopy training. For gastroscopy training, procedure completed independently was reported in 87.7% of participants in simulator training group compared to 70.0% of participants in control group (1 study; 22 participants; RR 1.25; 95% CI 1.13-1.39; Ptraining, procedure completed independently was reported in 89.3% of participants in simulator training group compared to 88.9% of participants in control group (7 study; 163 participants; RR 1.10; 95% CI 0.88-1.37; P = 0.41; I(2) = 85%). The included studies are quite in-homogeneous with respect to training schedule and procedure. Virtual endoscopy simulator training might be effective for gastroscopy, but so far no data is available to support this for colonoscopy.

    The IGS is a natural response, in the training area, to the high technological advances in the computer disciplines for the graphic representations and advanced process models with a high level of reliability and friendliness. Tecnatom has integrated a representation of advanced models in several workstations which permits, through its high resolution colour screens, the visualization of all the information available in control room with graphical representation of NPP's system. Simultaneously with this, the IGS permits to operate any component in order to change its status, in the same way that operations upon the panels. Through the flexibility of the software for graphic representations and the advanced models. Tecnatom has generated, based in the use of IGS, several training courses which have provided a tutorial worth, to understand complex phenomena, with a man-machine interface more friendly than the full scope simulator. Therefore, the IGS appears as an important flexible tool which can adapt itself to the training of several collectives in a NPP, and it has a special importance for those which the ignorance of panels interferes with the training in a full scope simulator.

    In situ simulation (ISS) is an emerging teaching strategy aimed to improve professionals' competencies and collaborative practice to increase patient safety The impact of ISS is still to be demonstrated before expanding the use of this method in our critical care settings. The objective of this paper is to explore the literature regarding ISS training and present advantages and challenges. An integrative review was conducted, based on the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement. Online databases MEDLINE and CINAHL were searched. The main keywords used were "in situ simulation", "communication" and "interdisciplinary". We excluded studies conducted outside of the hospital or the clinic, single case studies and framework analyses. Twenty-eight articles were reviewed. Studies were mainly descriptive and exploratory. They underlined the advantages and challenges of the ISS training regarding safety, as well as the perspectives of patients, families, health care providers and administrators. CONCLUSION AND NURSING IMPLICATIONS: Although ISS is a promising educational strategy to increase patient safety, there is still a need for higher evidence level research to support its efficacy to improve competencies. With regard to patient safety improvement, ISS-based training offers opportunities to identify hazards and deficiencies of clinical systems and the provider team. Experimental studies are necessary to increase evidence about the impact of ISS training.

The study design was a randomized controlled trial. Midwives working at one obstetrics ward in an urban area were randomly assigned to simulation training program or no training. This "simulation program" included pre study e-learning and simulation. Inclusion criteria were midwives who: 1) had two or three years of clinical experience, 2) worked in an obstetrics ward, and 3) had experience with birth assistance. There was one exclusion criterion namely prior experience of simulation training for PPH. Change in performance was evaluated using a PPH scenario performance test at one month after the simulation training. Change in knowledge was evaluated by a 25-item multiple-choice questionnaire completed shortly before the training and one month after the training. The ethical review committee of St Luke's International University granted approval (No. 14-096). Eighty-one midwives were randomly assigned to either the intervention group (n=40) or the control group (n=41). Performance in the simulation training group was significantly better in comparison to the no training group; mean performance score was 23.85(SD 2.71) in the training group versus 18.00(SD 3.01) in the no training group (MD 5.85 95% CI 4.85-7.12, t=9.17, pmanagement of PPH were significantly improved after simulation training. However, assessments of long-term effects on performance, and knowledge and the clinical outcomes in managing of obstetric complications are necessary to adequately evaluate the effectiveness of simulation training.

    Simulated practice may improve resident performance in endoscopic endonasal surgery. Using the NeuroTouch haptic simulation platform, we evaluated resident performance and assessed the effect of simulation training on performance in the operating room. First- (N=3) and second- (N=3) year residents were assessed using six measures of proficiency. Using a visual analog scale, the senior author scored subjects. After the first session, subjects with lower scores were provided with simulation training. A second simulation served as a task-learning control. Residents were evaluated in the operating room over six months by the senior author-who was blinded to the trained/untrained identities-using the same parameters. A nonparametric bootstrap testing method was used for the analysis (Matlab v. 2014a). Simulation training was associated with an increase in performance scores in the operating room averaged over all measures (p=0.0045). This is the first study to evaluate the training utility of an endoscopic endonasal surgical task using a virtual reality haptic simulator. The data suggest that haptic simulation training in endoscopic neurosurgery may contribute to improvements in operative performance. Limitations include a small number of subjects and adjudication bias-although the trained/untrained identity of subjects was blinded. Further study using the proposed methods may better describe the relationship between simulated training and operative performance in endoscopic Neurosurgery. Copyright © 2016 Elsevier Ltd.

    Video games contain elaborate reinforcement and reward schedules that have the potential to maximize motivation. Neuroimaging studies suggest that video games might have an influence on the reward system. However, it is not clear whether reward-related properties represent a precondition, which biases an individual toward playing video games, or if these changes are the result of playing video games. Therefore, we conducted a longitudinal study to explore reward-related functional predictors in relation to video gaming experience as well as functional changes in the brain in response to video game training. Fifty healthy participants were randomly assigned to a video game training (TG) or control group (CG). Before and after training/control period, functional magnetic resonance imaging (fMRI) was conducted using a non-video game related reward task. At pretest, both groups showed strongest activation in ventral striatum (VS) during reward anticipation. At posttest, the TG showed very similar VS activity compared to pretest. In the CG, the VS activity was significantly attenuated. This longitudinal study revealed that video game training may preserve reward responsiveness in the VS in a retest situation over time. We suggest that video games are able to keep striatal responses to reward flexible, a mechanism which might be of critical value for applications such as therapeutic cognitive training.

    Several research programs are tackling the use of Wireless Sensor Networks (WSN) at specific fields, such as e-Health, e-Inclusion or e-Sport. This is the case of the project "Ambient Intelligence Systems Support for Athletes with Specific Profiles", which intends to assist athletes in their training. In this paper, the main developments and outcomes from this project are described. The architecture of the system comprises a WSN deployed in the training area which provides communication with athletes' mobile equipments, performs location tasks, and harvests environmental data (wind speed, temperature, etc.). Athletes are equipped with a monitoring unit which obtains data from their training (pulse, speed, etc.). Besides, a decision engine combines these real-time data together with static information about the training field, and from the athlete, to direct athletes' training to fulfill some specific goal. A prototype is presented in this work for a cross country running scenario, where the objective is to maintain the heart rate (HR) of the runner in a target range. For each track, the environmental conditions (temperature of the next track), the current athlete condition (HR), and the intrinsic difficulty of the track (slopes) influence the performance of the athlete. The decision engine, implemented by means of (m, s)-splines interpolation, estimates the future HR and selects the best track in each fork of the circuit. This method achieves a success ratio in the order of 80%. Indeed, results demonstrate that if environmental information is not take into account to derive training orders, the success ratio is reduced notably.

    A robotic virtual reality simulator (Mimic dV-Trainer) can be a useful training method for the da Vinci surgical system. Herein, we investigate several repetitive training schedules and determine which is the most effective. A total of 30 medical students were enrolled and were divided into 3 groups according to the training schedule. Group 1 performed the task 1 hour daily for 4 consecutive days, group II performed the task on once per week for 1 hour for 4 consecutive weeks, and group III performed the task for 4 consecutive hours in 1 day. The effects of training were investigated by analyzing the number of repetitions and the time required to complete the "Tube 2" simulation task when the learning curve plateau was reached. The point at which participants reached a stable score was evaluated using the cumulative sum control graph. The average time to complete the task at the learning curve plateau was 150.3 seconds in group I, 171.9 seconds in group II, and 188.5 seconds in group III. The number of task repetitions required to reach the learning curve plateau was 45 repetitions in group I, 36 repetitions in group II, and 39 repetitions in group III. Therefore, there was continuous improvement in the time required to perform the task after 40 repetitions in group I only. There was a significant correlation between improvement in each trial interval and attempt, and the correlation coefficient (0.924) in group I was higher than that in group II (0.899) and group III (0.838). Daily 1-hour practice sessions performed for 4 consecutive days resulted in the best final score, continuous score improvement, and effective training while minimizing fatigue. This repetition schedule can be used for effectively training novices in future. Copyright © 2015 Association of Program Directors in Surgery. Published by Elsevier Inc. All rights reserved.

    Since Head Mounted Displays (HMD), datagloves, tracking systems, and powerful computer graphics resources are nowadays in an affordable price range, the usage of PC-based "Virtual Training Systems" becomes very attractive. However, due to the limited field of view of HMD devices, additional modalities have to be provided to benefit from 3D environments. A 3D sound simulation can improve the capabilities of VR systems dramatically. Unfortunately, realistic 3D sound simulations are expensive and demand a tremendous amount of computational power to calculate reverberation, occlusion, and obstruction effects. To use 3D sound in a PC-based training system as a way to direct and guide trainees to observe specific events in 3D space, a cheaper alternative has to be provided, so that a broader range of applications can take advantage of this modality. To address this issue, we focus in this paper on the evaluation of a low-cost 3D sound simulation that is capable of providing traceable 3D sound events. We describe our experimental system setup using conventional stereo headsets in combination with a tracked HMD device and present our results with regard to precision, speed, and used signal types for localizing simulated sound events in a virtual training environment.

    Postpartum hemorrhage (PPH) is a major cause of maternal morbidity and mortality. In Tanzania, PPH causes 25% of maternal deaths. Skilled attendance is crucial to saving the lives of mothers and their newborns during childbirth. This study is a follow-up after multi-professional simulation training on PPH in northern Tanzania. The purpose was to enhance understanding and gain knowledge of important learning features and outcomes related to multi-professional simulation training on PPH. The study had a descriptive and exploratory design. After the second annual simulation training at two hospitals in northern Tanzania, ten focus group discussions comprising 42 nurse midwives, doctors, and medical attendants, were carried out. A semi-structured interview guide was used during the discussions, which were audio-taped for qualitative content analysis of manifest content. The most important findings from the focus group discussions were the importance of team training as learning feature, and the perception of improved ability to use a teamwork approach to PPH. Regardless of profession and job tasks, the informants expressed enhanced self-efficacy and reduced perception of stress. The informants perceived that improved competence enabled them to provide efficient PPH management for improved maternal health. They recommended simulation training to be continued and disseminated. Learning features, such as training in teams, skills training, and realistic repeated scenarios with consecutive debriefing for reflective learning, including a systems approach to human error, were crucial for enhanced teamwork. Informants' confidence levels increased, their stress levels decreased, and they were confident that they offered better maternal services after training.

    Simulation-based training may be incorporated into neurosurgery in the future. To assess the usefulness of a novel haptics-based virtual reality percutaneous trigeminal rhizotomy simulator. A real-time augmented reality simulator for percutaneous trigeminal rhizotomy was developed using the ImmersiveTouch platform. Ninety-two neurosurgery residents tested the simulator at American Association of Neurological Surgeons Top Gun 2014. Postgraduate year (PGY), number of fluoroscopy shots, the distance from the ideal entry point, and the distance from the ideal target were recorded by the system during each simulation session. Final performance score was calculated considering the number of fluoroscopy shots and distances from entry and target points (a lower score is better). The impact of PGY level on residents' performance was analyzed. Seventy-one residents provided their PGY-level and simulator performance data; 38% were senior residents and 62% were junior residents. The mean distance from the entry point (9.4 mm vs 12.6 mm, P = .01), the distance from the target (12.0 mm vs 15.2 mm, P = .16), and final score (31.1 vs 37.7, P = .02) were lower in senior than in junior residents. The mean number of fluoroscopy shots (9.8 vs 10.0, P = .88) was similar in these 2 groups. Linear regression analysis showed that increasing PGY level is significantly associated with a decreased distance from the ideal entry point (P = .001), a shorter distance from target (P = .05), a better final score (P = .007), but not number of fluoroscopy shots (P = .52). Because technical performance of percutaneous rhizotomy increases with training, we proposed that the skills in performing the procedure in our virtual reality model would also increase with PGY level, if our simulator models the actual procedure. Our results confirm this hypothesis and demonstrate construct validity.

    Training in interventional radiology (IR) relies on a traditional apprenticeship; to protect patients, expert supervision is mandatory until knowledge, attitudes and practical skills have been certified as satisfactory. However, the current quality of IR training is threatened by reduced time for trainees to learn, as well as a loss of basic diagnostic, training cases to non-invasive imaging. At the same time, IR techniques are becoming a focus of interest to a range of other clinical specialities. To address this training shortfall there is a need to develop novel training alternatives such as simulator models. Few simulator models in any medical field have been successfully validated to show improved clinical skills in treating patients. To date no endovascular simulator has met this standard. A good simulator must be based around key performance measures (metrics) derived from careful analysis of the procedure to be replicated. Metrics can be determined by trained psychologists from a direct analysis of the content of the job or task to be tested. The identification of these critical measures of performance is a complex process which must be tailored to a training curriculum to be effective. Simulators based on flawed metrics will invariably lead to unsatisfactory assessment. It follows that simulator development must involve the statutory licensing authorities. Equally it is essential that we do not assume that training on a particular simulator will correlate with the ability to perform the task in the real world. This 'transfer of training' must be rigorously proven by validation studies

    This study aims to describe implementation of simulator-based medical team training and the effect of this programme on inter-professional working in an intensive care unit (ICU). Over a period of two years, 90 percent (n = 152) of the staff of the general ICU at Karolinska University Hospital, Huddinge, Sweden, received inter-professional team training in a fully equipped patient room in their own workplace. A case study method was used to describe and explain the planning, formation, and results of the training programme. In interviews, the participants reported that the training had increased their awareness of the importance of effective communication for patient safety. The intervention had even had an indirect impact by creating a need to talk, not only about how to communicate efficaciously, but also concerning difficult care situations in general. This, in turn, had led to regular reflection meetings for nurses held three times a week. Examples of better communication in acute situations were also reported. However, the findings indicate that the observed improvements will not last, unless organisational features such as staffing rotas and scheduling of rounds and meetings can be changed to enable use of the learned behaviours in everyday work. Other threats to sustainability include shortage of staff, overtime for staff, demands for hospital beds, budget cuts, and poor staff communication due to separate meetings for nurses and physicians. The present results broaden our understanding of how to create and sustain an organizational system that supports medical team training.

  3. Guidelines for upgrade and modernization of nuclear power plant training simulators

    International Nuclear Information System (INIS)

    2006-06-01

    The IAEA publication Safety Standards Series No. NS-G-2.8 (2002) Recruitment, Qualification and Training of Personnel for Nuclear Power Plants requires that 'Initial and continuing simulator based training for the control room shift team personnel should be conducted on a simulator that represents the control room. The simulator should have software of sufficient scope to cover normal operation, anticipated operational occurrences and a range of accident conditions. Other personnel may benefit from simulator based training'. A full scope control room simulator is the primary tool used for training control room operating personnel and represents a significant financial investment for a Nuclear Power Plant. Consequently, simulators should be maintained current with reference plant design changes and upgraded and modernized in a timely fashion to provide adequate capabilities for effective and reliable training and authorization of NPP personnel. The purpose of this publication is to provide practical guidance on various technical and project management aspects of the modernization and upgrade of Nuclear Power Plant control room simulators. The information in this publication is primarily intended for technical staff that maintain the hardware and software infrastructure of control room simulators. Information on simulator upgrade project management in this report may be useful to NPP and Training Department management, for regulatory body staff who supervise the availability of control room simulators, and for organizations supplying simulators

    Simulation training improves individual clinician confidence, performance and self-efficacy in resuscitation and procedural training experiences. The reality of resuscitation experiences in the neonatal intensive care unit (NICU) is that they are team-accomplished events. However, limited data exist on team-based simulation training (TBST) in the NICU. We report the experience of TBST over a 4-year period. This is a retrospective report of 65 TBST events in a 71-bed Level IV NICU at a regional subspecialty children's hospital. Participants were more than 500 NICU staff, including neonatal/cardiac/surgical attendings, neonatal fellows, neonatal nurse practitioners, pediatric residents, registered nurses and respiratory therapists. Background work, common case scenarios, training objectives and learning opportunities were reported, along with discipline-specific, and team and system areas for improvement. Qualitative, subjective data were tracked and efforts at collecting quantitative, objective data are ongoing. Seventy-five TBST events were scheduled from November 2010 through December 2014; 10 of these were canceled. TBST events occurred both night (n=23) and day (n=42), and also on weekends (n=19), using high-fidelity (n=42) and low-fidelity (n=23) systems. Resuscitation team participants at each TBST were 12-30 providers and staff. The duration of each TBST event was 30-65 min including debriefing. Systems issues were identified and corrected, including problems activating the code pathway, issues using a pager activation system and confusion over resuscitation team roles and responsibilities. Educational needs were addressed, focused on topic areas that included arrhythmias and use of extracorporeal cardiopulmonary resuscitation. With appropriate planning and implementation, TBST is feasible and realistic in a busy NICU.

    Minimally Invasive Surgery (MIS) has been widely used to perform any surgical procedures nowadays. Currently, MIS has been applied in some cases in Indonesia. Needle insertion is one of simple MIS procedure that can be used for some purposes. Before the needle insertion technique used in the real situation, it essential to train this type of medical student skills. The research has developed an open platform of needle insertion simulator with haptic feedback that providing the medical student a realistic feel encountered during the actual procedures. There are three main steps in build the training simulator, which are configure hardware system, develop a program to create soft tissue model and the integration of hardware and software. For evaluating its performance, haptic simulator was tested by 24 volunteers on a scenario of soft tissue model. Each volunteer must insert the needle on simulator until rearch the target point with visual feedback that visualized on the monitor. From the result it can concluded that the soft tissue model can bring the sensation of touch through the perceived force feedback on haptic actuator by looking at the different force in accordance with different stiffness in each layer.

  6. Integrating Existing Simulation Components into a Cohesive Simulation System

    A tradition of leveraging the re-use of components to help manage costs has evolved in the development of complex system. This tradition continues on in the Joint Polar Satellite System (JPSS) Program with the cloning of the Suomi National Polar-orbiting Partnership (NPP) satellite for the JPSS-1 mission, including the instrument complement. One benefit of re-use on a mission is the availability of existing simulation assets from the systems that were previously built. An issue arises in the continual shift of technology over a long mission, or multi-mission, lifecycle. As the missions mature, the requirements for the observatory simulations evolve. The challenge in this environment becomes re-using the existing components in that ever-changing landscape. To meet this challenge, the system must: establish an operational architecture that minimizes impacts on the implementation of individual components, consolidate the satisfaction of new high-impact requirements into system-level infrastructure, and build in a long-term view of system adaptation that spans the full lifecycle of the simulation system. The Flight Vehicle Test Suite (FVTS) within the JPSS Program is defining and executing this approach to ensure a robust simulation capability for the JPSS multi-mission environment

    Respiratory problems are among the main causes of mortality for preterm newborns with pulmonary diseases; mechanical ventilation provides standard care, but long-term complications are still largely reported. In this framework, continuous medical education is mandatory to correctly manage assistance devices. However, commercially available neonatal respiratory simulators are rarely suitable for representing anatomical and physiological conditions; a step toward high-fidelity simulation, therefore, is essential for nurses and neonatologists to acquire the practice needed without any risk. An innovative multi-compartmental infant respirator simulator based on a five-lobe model was developed to reproduce different physio-pathological conditions in infants and to simulate many different kinds of clinical scenarios. The work consisted of three phases: (1) a theoretical study and modeling phase, (2) a prototyping phase, and (3) testing of the simulation software during training courses. The neonatal pulmonary simulator produced allows the replication and evaluation of different mechanical ventilation modalities in infants suffering from many different kinds of respiratory physio-pathological conditions. In particular, the system provides variable compliances for each lobe in an independent manner and different resistance levels for the airway branches; moreover, it allows the trainer to simulate both autonomous and mechanically assisted respiratory cycles in newborns. The developed and tested simulator is a significant contribution to the field of medical simulation in neonatology, as it makes it possible to choose the best ventilation strategy and to perform fully aware management of ventilation parameters. © IMechE 2015.

The pattern of the control system was developed using as tool the nuclear code of simulation RELAP/SCDAP, designed for the analysis of the types of nuclear reactors more common in occident, and it allows the typical maneuvers in the ways of start up, heating and operation to power, showing an appropriate behavior during the more common operational transitoriness.

    : This study was conducted to compare the effectiveness of simulation-based ultrasound training in pairs (dyad practice) with that of training alone (single-student practice) on skills transfer. METHODS: In a non-inferiority trial, 30 ultrasound novices were randomised to dyad (n = 16) or single-student (n...... through pre-, post- and transfer tests. The transfer test involved the assessment of a transvaginal ultrasound scan by one of two clinicians using the Objective Structured Assessment of Ultrasound Skills (OSAUS). RESULTS: Thirty participants completed the simulation-based training and 24...... interactions between training type and performance (p = 0.59). The dyad group demonstrated higher training efficiency in terms of simulator score per number of attempts compared with the single-student group (p = 0.03). CONCLUSION: Dyad practice improves the efficiency of simulation-based training and is non...

    Simulation-based training is a widespread strategy to improve health-care quality. However, its effect on registered nurses has previously not been established in systematic reviews. The aim of this systematic review is to evaluate effect of simulation-based training on nurses' skills and knowledge. We searched CDSR, DARE, HTA, CENTRAL, CINAHL, MEDLINE, Embase, ERIC, and SveMed+ for randomised controlled trials (RCT) evaluating effect of simulation-based training among nurses. Searches were completed in December 2016. Two reviewers independently screened abstracts and full-text, extracted data, and assessed risk of bias. We compared simulation-based training to other learning strategies, high-fidelity simulation to other simulation strategies, and different organisation of simulation training. Data were analysed through meta-analysis and narrative syntheses. GRADE was used to assess the quality of evidence. Fifteen RCTs met the inclusion criteria. For the comparison of simulation-based training to other learning strategies on nurses' skills, six studies in the meta-analysis showed a significant, but small effect in favour of simulation (SMD -1.09, CI -1.72 to -0.47). There was large heterogeneity (I 2 85%). For the other comparisons, there was large between-study variation in results. The quality of evidence for all comparisons was graded as low. The effect of simulation-based training varies substantially between studies. Our meta-analysis showed a significant effect of simulation training compared to other learning strategies, but the quality of evidence was low indicating uncertainty. Other comparisons showed inconsistency in results. Based on our findings simulation training appears to be an effective strategy to improve nurses' skills, but further good-quality RCTs with adequate sample sizes are needed.

    A new auditory orientation training system was developed for blind people using acoustic virtual reality (VR) based on a head-related transfer function (HRTF) simulation. The present training system can reproduce a virtual training environment for orientation and mobility (O&M) instruction, and the trainee can walk through the virtual training environment safely by listening to sounds such as vehicles, stores, ambient noise, etc., three-dimensionally through headphones. The system can reproduce not only sound sources but also sound reflection and insulation, so that the trainee can learn both sound location and obstacle perception skills. The virtual training environment is described in extensible markup language (XML), and the O&M instructor can edit it easily according to the training curriculum. Evaluation experiments were conducted to test the efficiency of some features of the system. Thirty subjects who had not acquired O&M skills attended the experiments. The subjects were separated into three groups: a no-training group, a virtual-training group using the present system, and a real-training group in real environments. The results suggested that virtual-training can reduce "veering" more than real-training and also can reduce stress as much as real training. The subjective technical and anxiety scores also improved.
