Background The Bullard laryngoscope is useful for the management of a variety of airway management scenarios. Without the aid of a video system, teaching laryngoscopy skills occurs with indirect feedback to the instructor. The purpose of this study was to determine if use of a video system would speed the process of learning the Bullard laryngoscope or improve the performance (speed or success) of its use. Methods Thirty-six anesthesia providers with no previous Bullard laryngoscope experience were randomly divided into two groups: initial training (first 15 intubations) with looking directly through the eyepiece (n = 20), or with the display of the scope on a video monitor (n = 16). The subjects each then performed 15 Bullard intubations by looking directly through the eyepiece. Results There was not an overall significant difference in laryngoscopy or intubation times between the groups. When only the first 15 intubations were considered, the laryngoscopy time was shorter in the video group (26 +/- 24) than in the nonvideo group (32 +/- 34; P< 0.04). In the first 15 patients, there were fewer single attempts at intubation (67.9% vs 80.3%; P< 0.002) and more failed intubations (17.2% vs 6.0%; P< 0.0001) in the nonvideo group. Conclusions In conclusion, the authors have shown that use of a video camera decreases time for laryngoscopic view and improves success rate when the Bullard laryngoscope is first being taught to experienced clinicians. However, these benefits are not evident as more experience with the Bullard laryngoscope is achieved, such that no difference in skill with the Bullard laryngoscope is discernible after 15 intubations whether a video system was used to teach this technique.

AbstractObjective:This study aimed to estimate the effectiveness of a full digital, high definition video system for laryngeal observations.Methods:A newly available, full digital, high definition video camera and high definition video monitor were used. With an endoscopic adaptor and rigid telescope, laryngoscopy and stroboscopy were performed on patients with various kinds of laryngeal lesions.Results:All laryngeal lesions were observed and recorded by the full digital, high definition video camera without incident. The image quality for laryngoscopy and stroboscopy was far superior to that of a conventional video system, including video-endoscopy. Even tiny structures or lesions could clearly be visualised on the monitor. The still image obtained from the full digital, high definition video camera was 1920 × 1080 pixels and was comparable to that obtained from a still camera.Conclusions:Full digital, high definition video cameras are now commonplace products and can easily be applied to patients with laryngeal disorders. They provide superior laryngeal images, compared with conventional video systems. Furthermore, high definition video systems are cheaper than proprietary medical video systems. We consider our system to represent an accessible technique of gaining superior laryngeal observation in otolaryngological clinics.

The common problems faced by students in English speaking are anxiety and the lack of confidence and ideas. This research was conducted to determine the relevant factors and to provide a solution by using the smartphone video camera. To obtain the data in this research, experimental research was performed inside and outside the classroom with a series of treatments and a questionnaire sheet as the instrument. The data were analyzed using a model proposed by Smeda, Dakich, and Sharda (2014) and a Likert scale questionnaire, which was adapted from Spratt, Humphreys, and Chan (2002). The result from the test showed a significant difference between the experimental and control classes as the carried t-test presented the score of -8.36, which was out of the limit (between -1.96 and 1.96). Another result was the students developed positively which was shown by: the anxiety tends to decrease as they were given time before performing thus prepared better, their self-confidence was increased and challenged by using the smartphone video camera method due to the application of innovation in the speaking class. The conclusion of this research is lecturer needs to apply new methods, one of which is using a smartphone application.

In recent years, it has been shown that spacing training sessions by several hours allows the consolidation of motor skills in the brain, a process leading to the stabilization of the skills and, sometimes, further improvement without additional practice. At the moment, it is unknown whether consolidation can lead to an improvement in performance when the learner performs complex full-body movements. To explore this question, we recruited 10 divers and had them practice a challenging diving maneuver. Divers first performed an initial training session, consisting of 12 dives during which visual feedback was provided immediately after each dive through video replay. Two retention tests without feedback were performed 30 min and 24 hr after the initial training session. All dives were recorded using a video camera and the participants’ performance was assessed by measuring the verticality of the body segments at water entry. Significant performance gains were observed in the 24-hr retention test (p < .05). These results suggest that the learning of complex full-body movements can benefit from consolidation and that splitting practice sessions can be used as a training tool to facilitate skill acquisition.

A stereoscopic video system for use with Underwater Remotely Operated Vehicles (ROVs) has been developed by Curtin University's Centre for Marine Science and Technology. The system provides ROV operators with a fully three-dimensional (stereoscopic) view of the ROVs surroundings. This increased perception of depth offers several advantages to both the piloting of ROVs and also to the operation of an ROV manipulator arm.The stereoscopic video system consists of an underwater stereoscopic video camera which fits on the ROV and a stereoscopic display which is installed in the ship-based ROV control room. The system was developed in close cooperation with Woodside Offshore Petroleum which has used the system on their Triton ROV. Three ROVs are currently operated at Woodside's oil fields on Western Australia's North West Shelf.Field use of the system on the Triton ROV has revealed many advantages of stereoscopic video. One of the areas where advantages are particularly evident is in the operation of the manipulator arm. Operators have reported that it is perceptually easier to perform manipulator tasks. This is because the spatial relationship of objects can be immediately identified, making object placement and alignment easier. The system also provides a better understanding of the work site and a perceived improvement in image quality and therefore improved visibility.

The modern laparoscope relies on Hopkins’ glass rod lenses, a fiber-optic light source, a video camera, and external cables. This paper discusses the feasibility of developing an experimental prototype of a completely wireless laparoscope by making use of the latest in electronic and optic miniaturization. Design requirements were defined to mimic a standard 10 mm adult laparoscope. An 8 mm diameter (CMOS) camera was used, which delivered standard definition TV resolution at an image refresh rate of 30 Hz. A wide-angle lens was chosen, and a focusing mechanism was designed. Instead of a fiber-optic cable, illumination was achieved using four miniature LED lights. A 2.4 GHz wireless transmission with adequate range for use in an operating theater was chosen. A wireless receiver on a standard personal computer was used to drive a video monitor using off the shelf image processing software. A built-in rechargeable battery powered the wireless laparoscope. Flicker-free in vitro wireless video transmission was achieved. The laparoscope was made waterproof with a front cover lens and can be gas or chemically sterilized. The prototype laparoscope weights 78 g as compared with 900 g for a typical 10 mm laparoscope, camera, fiber-optic, and camera cables. Drawbacks of the prototype include reduced resolution of the video image as compared to high definition (HD) TV quality available on the most recent commercial camera systems. This experimental prototype has illustrated the feasibility of wireless endoscopy systems. The expected benefits include improved ergonomic maneuverability, reduced weight, and decreased electric power requirements.

Purpose: to develop and experimentally substantiate the effectiveness of the methodology for teaching the basic technique of free-style wrestling in combination with physical training. Material and methods. The study involved 16 young athletes, 8-9 years old, a group of initial training, the first year of training, who were engaged in the department of free-style wrestling KZ «KDYUSSH №4» in Kharkov. The boys were divided into two equal groups (experimental and control), according to the results of testing the level of development of physical abilities (p>0,05). An experimental methodology of basic technical training for young freestyle wrestlers of the initial level of training was developed, which consisted not only of means and methods of teaching certain elements of wrestling techniques, but also a large number of preparatory, special exercises, games and game tasks, different in coordination complexity. It was on the basis of versatile coordination training, which was solved mainly by the game method, that the experimental methodology of the basic technical training of young athletes was built. Research methods: analysis of scientific and methodological sources; generalization of the practical experience of practitioners; pedagogical observations; pedagogical experiment; pedagogical testing; method of expert assessments; methods of mathematical statistics. Results: the advantage of young wrestlers in the experimental group was determined by almost all the studied indicators. A regularity was noticed, with an increase in the complexity of the exercise, the difference in the quality of its fulfillment by young wrestlers from the experimental and control groups increased. In special exercises, these are running to the subdominant side (t=6,20; p˂0,001), and throwing off the legs from the passage (t=3,27; p˂0,01), in the study of the quality of performing techniques in the stalls - a coup coasting (t=3,33; p˂0,01) in the study of technical readiness in a standing position - an incline throw with a hold of the legs (t=3,68; p˂0,01) knocking down with a hold of the legs (t=3,24; p˂0,01), as well as maneuvering (t=3,37; p˂0,01). There was no significant difference in the quality of performance of technical actions between the experimental and control groups, only in four of the sixteen studied indicators (p>0,05). Conclusions. The effectiveness of the experimental methodology of basic technical training of young wrestlers, used in the group of initial training, has been proved. According to most of the studied indicators, the advantage of young wrestlers in the experimental group was determined (p˂0,05-p˂0,001). The following tendency is observed, with an increase in the coordination complexity of the studied technical actions or movements, the probability of differences between the quality of this action fulfillment by young athletes of the experimental and control groups increases, in favor of the former. Only in simpler, in terms of coordination structure, movements, the advantages of the experimental group under study, confirmed by mathematical calculations, were not revealed (p˂0,05). Keywords: freestyle wrestling, young wrestlers, initial training groups, basic technical training, coordination development.

There are numerous articles that study the ground reaction forces during the golf swing, among which only a few analyze the pressure pattern distributed on the entire surface of the foot. The current study compares the pressure patterns on the foot insoles of fifty-five golfers, from three different performance levels, playing swings with driver and 5-iron clubs in the driving range. Five swings were selected for each club. During each swing, ultra-thin insole sensors (4 sensors/cm^2) measure foot pressure at the frequency of 100 Hz. To perform statistical analysis, insole sensors are clustered to form seven areas, with the normalized pressure of each area being our dependent variable. A video camera was used to label the five key instants of the swing. Statistical analysis demonstrates a significant difference between the pressure distribution pattern of the left and right feet for both driver and 5-iron. However, the pressure distribution pattern remains almost the same when switching the club type from 5-iron to driver. We have also observed that there are significant differences between the pattern of professionals and players with medium and high handicap. The obtained pattern agrees with the principle of weight transfer with a different behavior between the medial and lateral areas of the foot.

BACKGROUND Visual Patient is an avatar-based alternative to standard patient monitor displays that significantly improves the perception of vital signs. Implementation of this technology in larger organizations would require it to be teachable by brief class instruction to large groups of professionals. Therefore, our study aimed to investigate the efficacy of such a large-scale introduction to Visual Patient. OBJECTIVE In this study, we aimed to compare 2 different educational methods, one-on-one instruction and class instruction, for training anesthesia providers in avatar-based patient monitoring. METHODS We presented 42 anesthesia providers with 30 minutes of class instruction on Visual Patient (class instruction group). We further selected a historical sample of 16 participants from a previous study who each received individual instruction (individual instruction group). After the instruction, the participants were shown monitors with either conventional displays or Visual Patient displays and were asked to interpret vital signs. In the class instruction group, the participants were shown scenarios for either 3 or 10 seconds, and the numbers of correct perceptions with each technology were compared. Then, the teaching efficacy of the class instruction was compared with that of the individual instruction in the historical sample by 2-way mixed analysis of variance and mixed regression. RESULTS In the class instruction group, when participants were presented with the 3-second scenario, there was a statistically significant median increase in the number of perceived vital signs when the participants were shown the Visual Patient compared to when they were shown the conventional display (3 vital signs, <i>P</i>&lt;.001; effect size –0.55). No significant difference was found for the 10-second scenarios. There was a statistically significant interaction between the teaching intervention and display technology in the number of perceived vital signs (<i>P</i>=.04; partial η<sup>2</sup>=.076). The mixed logistic regression model for correct vital sign perception yielded an odds ratio (OR) of 1.88 (95% CI 1.41-2.52; <i>P</i>&lt;.001) for individual instruction compared to class instruction as well as an OR of 3.03 (95% CI 2.50-3.70; <i>P</i>&lt;.001) for the Visual Patient compared to conventional monitoring. CONCLUSIONS Although individual instruction on Visual Patient is slightly more effective, class instruction is a viable teaching method; thus, large-scale introduction of health care providers to this novel technology is feasible.

Introduction Mathematical ability and numeracy skills are fundamental requirements for healthcare professionals undertaking patient management in a range of healthcare settings. The objective of this study was to ascertain the mathematical and drug calculation ability of undergraduate paramedic students at an Australian university in the state of Queensland. Methods This study utilised a cross-sectional study design with a previously used paper-based questionnaire to elicit responses about a range of mathematical calculations. A total of 185 Bachelor of Paramedicine students were eligible for this study. The drug calculations were provided using common pre-hospital management scenarios plus additional basic mathematical calculations. Students had no knowledge of the study before receiving the questionnaire at the end of a lecture. Descriptive and inferential statistics were used to report on demographic information and comparisons. Results There were 139 (75.1%) students who participated. Females comprised 59% of the total students with most students less than 25 years of age. Three (2.2%) students answered all questions correctly, however 56 (40.3%) students scored 50% or less. There were 102 (73.4%) conceptual errors, 111 (79.9%) arithmetical errors, and 29 (20.9%) computational errors. There was no statistically significant difference between females and males for the total of correct answers or the types of calculation errors. Conclusion Results from this study demonstrate that paramedic students from an Australian university struggle to solve basic mathematical calculations unaided in a classroom environment. Universities need to ensure mathematical capability with mastery testing, so they are safe when administering drugs on entering the workforce.
