Simulation Environments

Today, virtual simulation environments create alternative hands-on practice opportunities for surgical training. In order to increase the potential benefits of such environments, it is critical to understand the factors that influence them. This study was conducted to determine the effects of training, used-hand, and experience, as well as the interactions between these variables, on endoscopic surgery skills in an educational computer-based surgical simulation environment. A 2-hour computer-based endoneurosurgery simulation training module was developed for this study. Thirty-one novice- and intermediate-level resident surgeons from the departments of neurosurgery and ear, nose, and throat participated in this experimental study. The results suggest that a 2-hour training during a 2-month period through computer-based simulation environment improves the surgical skills of the residents in both-hand tasks, which is necessary for endoscopic surgical procedures but not in dominant hand tasks. Based on the results of this study, it can be concluded that computer-based simulation environments potentially improve surgical skills; however, the scenarios for such training modules need to consider especially the bimanual coordination of hands and should be regularly adapted to the individual skill levels and progresses.

The One

The advantage of simulation environments is that they present various insights into real situations, where experimental research opportunities are very limited—for example, in endoscopic surgery. These operations require simultaneous use of both hands. For this reason, surgical residents need to develop several motor skills, such as eye-hand coordination and left-right hand coordination. While performing these tasks, the hand condition (dominant, nondominant, both hands) creates different degrees of mental workload, which can be assessed through mental physiological measures—namely, pupil size. Studies show that pupil size grows in direct proportion to mental workload. However, in the literature, there are very limited studies exploring this workload through the pupil sizes of the surgical residents under different hand conditions. Therefore, in this study, we present a computer-based simulation of a surgical task using eye-tracking technology to better understand the influence of the hand condition on the performance of skill-based surgical tasks in a computer-based simulated environment. The results show that under the both-hand condition, the pupil size of the surgical residents is larger than the one under the dominant and nondominant hand conditions. This indicates that when the computer-simulated surgical task is performed with both hands, it is considered more difficult than in the dominant and nondominant hand conditions. In conclusion, this study shows that pupil size measurements are sufficiently feasible to estimate the mental workload of the participants while performing surgical tasks. The results of this study can be used as a guide by instructional system designers of skill-based training programs.

INTRODUCTION: The surgeon's formation process has changed in recent decades. The increase in medical schools, new specialties and modern technologies induce an overhaul of medical education. Medical residency in surgery has established itself as a key step in the formation of the surgeon, and represents the ideal and natural way for teaching laparoscopy. However, the introduction of laparoscopic surgery in the medical residency programs in surgical specialties is insufficient, creating the need for additional training after its termination. OBJECTIVE: To review the surgical teaching ways used in services that published their results. METHODS: Survey of relevant publications in books, internet and databases in PubMed, Lilacs and Scielo through july 2014 using the headings: laparoscopy; simulation; education, medical; learning; internship and residency. RESULTS: The training method for medical residency in surgery focused on surgical procedures in patients under supervision, has proven successful in the era of open surgery. However, conceptually turns as a process of experimentation in humans. Psychomotor learning must not be developed directly to the patient. Training in laparoscopic surgery requires the acquisition of psychomotor skills through training conducted initially with surgical simulation. Platforms based teaching problem solving as the Fundamentals of Laparoscopic Surgery, developed by the American Society of Gastrointestinal Endoscopic Surgery and the Laparoscopic Surgical Skills proposed by the European Society of Endoscopic Surgery has been widely used both for education and for the accreditation of surgeons worldwide. CONCLUSION: The establishment of a more appropriate pedagogical process for teaching laparoscopic surgery in the medical residency programs is mandatory in order to give a solid surgical education and to determine a structured and safe professional activity.

The Impact

The National Department of Health invited comments on proposed policy guidelines on the prevention of physical inactivity in older persons at primary level. The guidelines recommended the use of exercises which are dynamic, interesting, fun, easily implemented, safe and tailored to suit the individual needs. In order to make informed comments on the policy, the aim of this study was to evaluate the impact of the recommended exercise program among older persons in a local community over a six-week period. Promoting physical activity among the participants in the study resulted in marked improvements in systolic and diastolic blood pressures, and dominant hand grip strength. The time taken to perform some selected functional tasks also improved. The findings gave credence to the need to discourage physical inactivity among older persons, but there is need to overcome formidable methodological problems in evaluating the effects of exercise intervention among older persons in the community.

The surgical skills required to successfully maintain hemostasis, the control of operative blood, requires considerable deliberate practice. Hemostasis requires the deft orchestration of bi-dexterous tool manipulation. We present our approach to computationally emulate both irrigation and bleeding associated with neurotologic surgical technique. The overall objective is to provide a visually plausible, three dimensional, real-time simulation of bleeding and irrigation in a virtual otologic simulator system. The results present a unique simulation environment for deliberate study and practice.

There is a pressing need for an evaluation rubric that examines all aspects of educational apps designed for instructional purposes. In past decades, many rubrics have been developed for evaluating educational computer-based programs; however, rubrics designed for evaluating the instructional implications of educational apps are scarce. When an Internet search for existing rubrics was conducted, only two such rubrics were found, and the evaluation criteria used in those rubrics was not clearly linked to previously conducted research nor were their evaluative dimensions clearly defined. These shortcomings result in reviewers being unable to use those rubrics to provide teachers with a precise analysis of an educational app’s instructional potential. In response, this paper presents a comprehensive rubric with 24-evaluative dimensions tailored specifically to analyze the educational potential of instructional apps.

This chapter presents an overview of accessibility and usability for educational computer-based games and the first survey of the accessibility and usability of digital educational games. The overview includes a discussion of accessibility and usability, both in general and in the specific context of educational games, as well as a brief presentation of issues relating to game design, including of mobile games. Since there are no previous studies of the accessibility and usability of educational computer-based games, studies of the accessibility and usability of the related areas of virtual learning environments, digital games for entertainment and PDF documents, are also presented. The overview of accessibility and usability and the results of the survey are used to draw up a structured list of 62 guidelines and recommendations, organised into three categories at the first level and ten at the second level. These guidelines and recommendations are illustrated by an example of their application to a fictitious new educational game.

The availability of web- and mobile-based technologies (WMBTs) for dementia prevention and care has grown exponentially over the last decade. These include computer-based resources such as online self-diagnostic tools, mobile-based resources such as applications (“apps”) that track lifestyle metrics or provide interactive platforms for cognitive engagement, and cross-platform resources such as websites providing health information. Despite their potential benefits, key ethical challenges have been identified in WMBTs for dementia both at the individual and societal levels, including issues of privacy, quality, and accessibility. This chapter explores the ethical challenges surrounding the use of WMBTs for dementia and highlights recent evidence on the positive and negative impacts of WMBT solutions. The chapter reviews development and design recommendations that have been put forward to maximize the benefits and minimize the harms of using WMBTs for dementia. It closes by looking to the future and proposing development considerations for future WMBT development.

The Individual

KABISA is a computer-based program for training in diagnostic problems in (sub-) tropical regions. It challenges the individual student with a randomly generated case, for which he should try to find the diagnosis, asking questions, performing a physical examination, and ordering tests. The built-in tutor follows the student’s input with complex logical algorithms and mathematical computations, gives comments and support, and accepts the final diagnosis if sufficient evidence has been built up. Several problems arose with the development. In the first place, the evolution in the teaching of clinical logic is always ahead of the program, so regular updating of the computer logic is necessary. Secondly, the choice of MS Access as computer language has provoked problems of stability, especially the installation of an MSAccess runtime. Thirdly, and most importantly, scholars want proof of the added value of computer programs over classical teaching. Moreover, the concept of a pedagogical “game” is often regarded as childish. Finally, the planning and financing of an “open-ended” pedagogical project is questioned by deciders, as is the case with all operational research.
