Active Training

The objective of this research is to evaluate the efficacy of an active colonoscopy training model (ACTM). Colonoscopy is a widely utilized procedure for diagnosing diseases of the lower gastrointestinal tract. Since colonoscopy is a difficult procedure to teach, as well as learn, simulators are often used to teach and practice the procedure. To make learning and assessing the procedural skills easy and interactive, an active training model was developed and evaluated. To measure the applied force and the time to complete the procedure, load cells and light detecting sensors were installed in the training model and were interfaced with a data acquisition system. The user interface was programmed in LabVIEW to record the force data and time taken to complete the procedure. Thirty medical students were recruited to perform a series of three colonoscopies on the ACTM. These students were instructed how to handle the equipment and perform the colonoscopy. The procedure was also performed by experienced endoscopists to establish a benchmark. The collected data were analyzed to determine the effectiveness of the device to (1) distinguish between the participants based on their level of expertise, and (2) to detect improvement in skill of the students with repetitive sessions with the device. The results of this research may be useful to show that the ACTM may be an effective tool to integrate in to the medical training program of medical studies. It can be possibly used for evaluating the skill sets, as well as practicing the procedure before a novice surgeon performs the procedure on a patient.

In the present work, an experimental analysis was performed to obtain the calibration curve of three load cells connected in series. The control of the load applied on a given component is an important factor in some engineering applications, for example, in cases where it is desired to increase the heat exchange between two surfaces. One of the ways to control the applied load is the use of load cells, which has as its principle of use a strain gauge that has its resistance varied when it undergoes a deformation, thus causing a voltage variation due to the application of load. This study used an ArduinoTM microcontroller as a data acquisition system and blocks with known mass for load application.  In this way it was possible to obtain the calibration curve of the load cells by means of linear regression between the mass of the blocks and the data obtained by the ArduinoTM microcontroller and verify their applicability according to their measurement uncertainties.

Abstract Millions of people have reduced hand function; this loss of function can be due to injury, disease, or aging. Loss of hand function is identified as reduced motion abilities in the fingers or a decrease in the ability of the fingers to generate force. Unfortunately, there are limited data available regarding each finger's ability to produce force and how those force characteristics vary with changes in finger posture. To relate motion and force abilities of the fingers, first, an approach to measure and map them together is needed. The goal of this work was to develop and demonstrate a method to quantify the force abilities of the fingers and map these forces to the kinematic space associated with each finger. Using motion capture and multiaxis load cells, finger forces were quantified at different positions over their ranges of motion. These two sets of data were then converted to the same coordinate space and mapped together. Further, the data were normalized for the index finger and mapped as a population space model. The ability to quantify motion and force data for each finger and map them together will provide an improved understanding of the effects of treatments and rehabilitation, identifying functional loss due to injury or disease, and device design.

This study aims to assess the role and importance of Soft skills-based training in the hotels of Delhi NCR (national capital region). Such skill sets are required to motivate the employees so that they can work effectively and efficiently. The study signifies that such essential skills (e.g., team management skills, problem solving and conflict resolution, technical skills, communication and presentation skills, self-discipline, computer skills) are not only important for the personnel associated with hospitality industry but at the same time such skills helps in employee retention also. Data was collected through a questionnaire on Likert scale of 5 during a period of 9 weeks between October and November 2019. The findings suggested that employee retention which is a major issue in hospitality industry can be tackled when the service employees through proper training are coupled with the above-mentioned skillsets. This in turn can contribute significantly towards increased guest satisfaction, retention of both guests and employees and hence leading to increased revenue generation.

The second half of the nineteenth century witnessed a radical change in the attitude of missionary societies to medicine as an aid to evangelism. For the first fifty or sixty years of the century the talents of the medical doctor were seldom sought and, when they were, it was most often to provide protection for missionaries in areas of particular health hazard. In 1852 it was calculated that there were only thirteen European medical missionaries, and in the period 1851-70 the Church Missionary Society (CMS) recruited seven doctors out of a total of three hundred and seven new missionaries. Suitably qualified applicants were not encouraged. In 1842 the CMS informed a surgeon of their willingness to employ him as a catechist on the clear understanding that medicine ‘was only to be an occasional occupation’. James Henderson, an Edinburgh trained doctor, could find no openings as a medical missionary in 1858. In 1861 Henry Venn, the CMS secretary, told an applicant, who was contemplating medical training, that it was inadvisable to devote time to medicine or surgery because when a candidate ‘attempts to qualify himself by medical studies, it very seldom answers any good purpose’. As late as 1875, J. K. Mackenzie, MRCS (London) and LRCP (Edinburgh), applied to the London Missionary Society (LMS) and ‘was treated altogether ... as if I had come up to ask for a special favour, or a situation, at their hands’.

IntroductionThere has been increased international awareness and a need to provide accessible and essential emergency preparedness training in developing countries that has resulted in the recognition of new teaching needs and number of new initiatives to meet these needs.MethodsThese teaching methods have been applied in Haiti before and after the 2010 earthquake. They include: - Established a “Train the trainer” model - Established civilian first responder training - Basic Life Support (BLS) and First Aid - Implemented medical training using the Meti Simulator models - Conducted post-training Disaster drill - Conduction of post training assessment - Succession model of training.ResultsA total of 54 people completed a BLS course and 67 completed a First Aid course. 12 participants completed the First Aid and BLS Instructors course. 95 program participants completed an end of course survey. 41 participants had no prior BLS/First Aid training or exposure. The course participants included 2 physicians, 22 students, 8 nursing students, 7 nurses, 20 teachers, 12 health workers, 5 drivers, and 14 laborers. 92 of those surveyed stated they would recommend this course to a friend. 88 participants stated that hands on learning helped them better learn the course material.ConclusionThis training model has been well received in rural Haiti and can be applied in other developing countries. We would like to standardize training protocols that will serve as a foundation for self-sustaining higher-level emergency, pre-hospital, disaster training and management. This will improve the general quality of health care delivery. Our next pilot of this program will be in other parts of Haiti and in Khartoum, Sudan.

Abstract Background: Understanding middle ear anatomy, in addition to endoscopic surgical skill acquisition, is an arduous task. Mastering 3-dimensional conceptualization and surgical dexterity may take many years. The coronavirus pandemic has made training difficult and complicated due to social distancing and risk of aerosolized viral spread in cadaver dissection. In this study we suggest a smartphone-based endoscope ovine head cadaveric dissection which is a simple, safe, and affordable training model for residents as an initial step in otologic endoscopic surgery training.Methods: A stepwise depiction of endoscopic ovine middle ear surgery; from cadaver and equipment acquisition, setting preparation, to surgical explanation and procedural steps. Results: The smartphone-based endoscopic otological ovine dissection model provides a low-cost, easily accessible and easily deployable training model for the novice surgeon world-wide. This model permits the novice surgeon a comprehensive anatomical understanding, middle ear proprioception, as well as a "safe" practicing model for diverse middle ear procedures. Conclusions: The ovine cadaver otological smartphone-based endoscopic surgery training model is an affordable, easy, reproducible, and transportable model, which makes it an ideal model from implementation in both low-middle and high-income countries.

Bruising is an early sign of child abuse. Bruising locations on the body can be an effective delineator of abusive vs. accidental trauma. However, the ability to predict potential bruising locations associated with falsely reported events (e.g. bed falls, stair falls) in child abuse does not exist. In our study we adapted an existing pediatric anthropomorphic test device (ATD) with custom developed force sensors integrated into a conformable skin. The sensors were coupled to a data acquisition system through which recorded force data was displayed on a computerized body mapping image system. A simulated abdominal blow demonstrated the modified ATD's capability to predict potential bruising location and impact force.

Several studies have investigated paddle force on the water. However, a limited number of studies have investigated on-water footrest forces. The purpose of this study was to design, implement, and validate a device which measures forces applied to the footrest during on-water kayaking without hindering the athletes’ performance. A Nelo footrest was modified and equipped with two load cells. The footrest was calibrated by loading it with known weights perpendicular to the surface of the footrest. A portable custom-built data acquisition system was built. The data acquisition system was placed in a box behind the seat in the kayak. The system was able to measure the paddling technique related to the legs during on-water testing and distinguish between different intensities. The system developed in the current study can help to improve kayak sprint performance in new ways, as the system elucidates forces within the kayak. Moreover, the system can provide clarification of the biomechanical aspects of the leg push during sprint kayaking.
