Birthing in health facilities in India has increased over the last few years, yet maternal and neonatal mortality rates remain high. Clinical mentoring with case sheets or checklists for nurses is viewed as essential for on-going knowledge transfer, particularly where basic training is inadequate. This paper summarizes a study of the effect of such a programme on staff knowledge and skills in a randomized trial of 295 nurses working in 108 Primary Health Centres (PHCs) in Karnataka, India. Stratifying by district, half of the PHCs were randomly assigned to be intervention sites and provided with regular mentoring visits where case sheet/checklists were a central job and teaching aid, and half to be control sites, where no support was provided except provision of case sheets. Nurses' knowledge and skills around normal labour, labour complications and neonate issues were tested before the intervention began and again one year later. Univariate and multivariate analyses were conducted to examine the effect of mentoring and case sheets. Overall, on none of the 3 measures, did case sheet use without mentoring add anything to the basic nursing training when controlling for other factors. Only individuals who used both case-sheets and received mentoring scored significantly higher on the normal labour and neonate indices, scoring almost twice as high as those who only used case-sheets. This group was also associated with significantly higher scores on the complications of labour index, with their scores 2.3 times higher on average than the case sheet only control group. Individuals from facilities with 21 or more deliveries in a month tended to fare worse on all 3 indices. There were no differences in outcomes according to district or years of experience. This study demonstrates that provision of case sheets or checklists alone is insufficient to improve knowledge and practices. However, on-site mentoring in combination with case sheets can have a demonstrable effect on improving nurse knowledge and skills around essential obstetric and neonatal care in remote rural areas of India. We recommend scaling up of this mentoring model in order to improve staff knowledge and skills and reduce maternal and neonatal mortality in India.

To evaluate the effect of our large-sized silicone sheet upon postoperative recovery of mastoid aeration in ears after surgery including mastoidectomy and soft-wall reconstruction (SWR). Retrospective chart review in a tertiary care center. Recovery of mastoid aeration was assessed by CT 4 to 12 months after surgery on 72 ears (69 patients), in which the silicone sheet covering from the eustachian tube (ET) to the mastoid was placed after SWR procedure with mastoidectomy were done for their chronic otitis media. Results were compared with those with a small silicone sheet. Recovery of mastoid aeration was significantly better in the large-silicone-sheet group than in the small-silicone-sheet group (chi(2) value = 11.7146, P = 0.0006). This preliminary study suggested that our large-sized silicone sheet may be effective for postoperative recovery of mastoid aeration even in ears operated with SWR procedure.

2001-07-01

Topical silicone gel sheeting has been used for more than 20 years to help reduce the size of hypertrophic scars and keloids. Its clinical efficacy and safety is well established. To determine whether topical silicone gel sheeting can be used to prevent hypertrophic scars and keloids from forming following dermatologic skin surgery. Patients undergoing skin surgery were stratified into two groups: those with no history of abnormal scarring (low-risk group) and those with a history of abnormal scarring (high-risk group). Following the procedure, patients within each group were randomized to receive either routine postoperative care or topical silicone gel sheeting (48 hours after surgery). Patients were followed for 6 months. In the low-risk group, there were no statistical differences between individuals using routine postoperative care or using topical silicone gel sheets. In the high-risk group, there was a statistical difference (39% versus 71%) between patients who did not develop abnormal scars and used topical silicone gel sheeting and patients who developed abnormal scars after routine postoperative treatment. Those individuals having a scar revision procedure also showed a statistical difference if topical silicone gel sheeting was used following surgery. Topical silicone gel sheeting, with a 20-year history of satisfaction in dermatology, now appears to be useful in the prevention of hypertrophic scars and keloids in patients undergoing scar revision.

Data Entry Skills in a Computer-based Spread Sheet Amongst Postgraduate Medical Students: A Simulation Based Descriptive Assessment.

PubMed

Khan, Amir Maroof; Shah, Dheeraj; Chatterjee, Pranab

2014-07-01

In India, research work in the form of a thesis is a mandatory requirement for the postgraduate (PG) medical students. Data entry in a computer-based spread sheet is one of the important basic skills for research, which has not yet been studied. This study was conducted to assess the data entry skills of the 2(nd) year PG medical students of a medical college of North India. A cross-sectional, descriptive study was conducted among 111 second year PG students by using four simulated filled case record forms and a computer-based spread sheet in which data entry was to be carried out. On a scale of 0-10, only 17.1% of the students scored more than seven. The specific sub-skills that were found to be lacking in more than half of the respondents were as follows: Inappropriate coding (93.7%), long variable names (51.4%), coding not being done for all the variables (76.6%), missing values entered in a non-uniform manner (84.7%) and two variables entered in the same column in the case of blood pressure reading (80.2%). PG medical students were not found to be proficient in data entry skill and this can act as a barrier to do research. This being a first of its kind study in India, more research is needed to understand this issue and then include this yet neglected aspect in teaching research methodology to the medical students.

Do procedural skills workshops during family practice residency work?

To determine if participation in a procedural skills workshop during family practice residency affects future use of these skills in postgraduate clinical practice. Survey involving self-assessment of procedural skills experience and competence. British Columbia. Former University of British Columbia family practice residents who trained in Vancouver, BC, including residents who participated in a procedural skills workshop in 2001 or 2003 and residents graduating in 2000 and 2002 who did not participate in the procedural skills workshop. Self-assessed experience and competence in the 6 office-based procedural skills that were taught during the procedural skills workshops in 2001 and 2003. Participation in a procedural skills workshop had no positive effect on future use of these skills in clinical practice. Participation in the workshop was associated with less reported experience (P = .091) in injection of lateral epicondylitis. As with previous Canadian studies, more women than men reported experience and competence in gynecologic procedures. More women than men reported experience (P = .001) and competence (P = .004) in intrauterine device insertion and experience (P = .091) in endometrial aspiration biopsy. More men than women reported competence (P = .052) in injection of trochanteric bursae. A third year of emergency training was correlated with an increase in reported experience (P = .021) in shoulder injection. Participation in a procedural skills workshop during family practice residency did not produce a significant increase in the performance of these skills on the part of participants once they were in clinical practice. The benefit of a skills workshop might be lost when there is no opportunity to practise and perfect these skills. Sex bias in the case of some procedures might represent a needs-based acquisition of skills on the part of practising physicians. Short procedural skills workshops might be better suited to graduated physicians with more clinical experience.

Although ice sheet models are used for sea level rise projections, the degree to which these models have been validated by observations is fairly limited, due in part to the limited duration of the satellite observation era and the long adjustment time scales of ice sheets. Here we describe a validation framework for the Greenland Ice Sheet applied to the Community Ice Sheet Model by forcing the model annually with flux anomalies at the major outlet glaciers (Enderlin et al., 2014, observed from Landsat/ASTER/Operation IceBridge) and surface mass balance (van Angelen et al., 2013, calculated from RACMO2) for the period 1991-2012. The ice sheet model output is compared to ice surface elevation observations from ICESat and ice sheet mass change observations from GRACE. Early results show promise for assessing the performance of different model configurations. Additionally, we explore the effect of ice sheet model resolution on validation skill.

Challenges faced by ice sheet projections: lessons from the SeaRISE effort

NASA Astrophysics Data System (ADS)

Nowicki, S.

2013-12-01

Projecting the future evolution of the Greenland and Antarctic ice sheets is a problem of enormous societal importance, as ice sheet influence our future sea levels. This crucial issue is however a non trivial task, as demonstrated by the Sea level Response to Ice Sheet Evolution (SeaRISE) effort: prescribing simple external forcings to a group of ice sheet models results in a spread in responses. Understanding the source of the diversity in the model results is therefore crucial in order to reduce the uncertainty in the projection. Just as in any future climate simulation, the analysis presented here demonstrates that the model spread in the SeaRISE effort is due to a number of factors. First is the problem of obtaining an initial configuration for the projection. The two commonly used methods, interglacial spin-up or data assimilation, have both advantages and drawbacks, and will affect the determination of fields that cannot be measured (such as basal slipperiness). Second is the uncertainty in actual observations, which includes but is not limited to surface mass balance, basal topography, ice thickness, and surface velocities. An additional issue with these observations is that they can be transient quantities which are not measured at the same time, but ice sheet models require them to be simultaneous. Third is the uncertainty in the models' physics and discretization, which is limited by our understanding (or lack of understanding) of crucial processes that often occur at subgrid scale relative to the resolution used by continental ice sheet models, and thus require parameterization. Grounding line migration and sliding laws are such an example. Fourth is the determination of the future forcing scenarios and their implementation as the external forcing. Unfortunately, as demonstrated in this analysis, all ice sheet models face these limitations to some degree, so that it is extremely difficult to identify a set of models and projections that should be trusted in preference to others. One model might be more suitable for assessing the impact of a warmer atmosphere because of its initialization procedure, but its deficiencies in capturing grounding line migration, for example, might make its projections for oceanic forcing unreliable. More work is thus required to evaluate individual ice sheet models' skills in projection, but this crucial and challenging task is left for future studies.

Learn, see, practice, prove, do, maintain: an evidence-based pedagogical framework for procedural skill training in medicine.

2015-08-01

Acquisition of competency in procedural skills is a fundamental goal of medical training. In this Perspective, the authors propose an evidence-based pedagogical framework for procedural skill training. The framework was developed based on a review of the literature using a critical synthesis approach and builds on earlier models of procedural skill training in medicine. The authors begin by describing the fundamentals of procedural skill development. Then, a six-step pedagogical framework for procedural skills training is presented: Learn, See, Practice, Prove, Do, and Maintain. In this framework, procedural skill training begins with the learner acquiring requisite cognitive knowledge through didactic education (Learn) and observation of the procedure (See). The learner then progresses to the stage of psychomotor skill acquisition and is allowed to deliberately practice the procedure on a simulator (Practice). Simulation-based mastery learning is employed to allow the trainee to prove competency prior to performing the procedure on a patient (Prove). Once competency is demonstrated on a simulator, the trainee is allowed to perform the procedure on patients with direct supervision, until he or she can be entrusted to perform the procedure independently (Do). Maintenance of the skill is ensured through continued clinical practice, supplemented by simulation-based training as needed (Maintain). Evidence in support of each component of the framework is presented. Implementation of the proposed framework presents a paradigm shift in procedural skill training. However, the authors believe that adoption of the framework will improve procedural skill training and patient safety.

Improved staff procedure skills lead to improved managment skills: an observational study in an educational setting.

PubMed

Rüter, Anders; Vikstrom, Tore

2009-01-01

Good staff procedure skills in a management group during incidents and disasters are believed to be a prerequisite for good management of the situation. However, this has not been demonstrated scientifically. Templates for evaluation results from performance indicators during simulation exercises have previously been tested. The aim of this study was to demonstrate the possibility that these indicators can be used as a tool for studying the relationship between good management skills and good staff procedure skills. Good and structured work (staff procedure skills) in a hospital management group during simulation exercises in disaster medicine is related to good and timely decisions (good management skills). Results from 29 consecutive simulation exercises in which staff procedure skills and management skills were evaluated using quantitative measurements were included. The statistical analysis method used was simple linear regression with staff procedure skills as the response variable and management skills as the predictor variable. An overall significant relationship was identified between staff procedure skills and management skills (p(2)0.05). This study suggests that there is a relationship between staff procedure skills and management skills in the educational setting used. Future studies are needed to demonstrate if this also can be observed during actual incidents.

Medical students have limited confidence in performing procedural skills. A pilot study was conducted to evaluate the effect of a multifaceted Procedural Skills Lab (PSL) on the confidence of medical students to perform procedural skills. Twelve 2nd year medical students were randomly selected to participate in a pilot PSL. The PSL students met with an instructor for 2 h once a week for 4 weeks. Students participated in a flipped classroom and spaced education program before laboratory sessions that included a cadaver laboratory. Procedural skills included a focused assessment with sonography in trauma (FAST) scan, cardiac echocardiogram, lumbar puncture, arthrocentesis, and insertion of intraosseous and intravenous catheters. Students in the PSL were asked to rank their confidence in performing procedural skills before and after completion of the laboratory sessions (Wilcoxon ranked-sum test). A web-based questionnaire was also emailed to all 2nd year medical students to establish a baseline frequency for observing, performing, and confidence performing procedural skills (Mann-Whitney U-test). Fifty-nine percent (n = 106) of 180 2nd year medical students (n = 12 PSL students [treatment group], n = 94 [control group]) completed the survey. Frequency of observation, performance, and confidence in performing procedural skills was similar between the control and treatment groups at baseline. There was an increased confidence level (p < 0.001) for performing all procedural skills for the treatment group after completion of the PSL. An innovative PSL may increase students' confidence to perform procedural skills. Future studies will examine competency after a PSL.

Graduating Internal Medicine residents must possess sufficient skills to perform a variety of medical procedures. Little is known about resident experiences of acquiring procedural skills proficiency, of practicing these techniques, or of being assessed on their proficiency. The purpose of this study was to qualitatively investigate resident 1) experiences of the acquisition of procedural skills and 2) perceptions of procedural skills assessment methods available to them. Focus groups were conducted in the weeks following an assessment of procedural skills incorporated into an objective structured clinical examination (OSCE). Using fundamental qualitative description, emergent themes were identified and analyzed. Residents perceived procedural skills assessment on the OSCE as a useful formative tool for direct observation and immediate feedback. This positive reaction was regularly expressed in conjunction with a frustration with available assessment systems. Participants reported that proficiency was acquired through resident directed learning with no formal mechanism to ensure acquisition or maintenance of skills. The acquisition and assessment of procedural skills in Internal Medicine programs should move toward a more structured system of teaching, deliberate practice and objective assessment. We propose that directed, self-guided learning might meet these needs.

Data assimilation and prognostic whole ice sheet modelling with the variationally derived, higher order, open source, and fully parallel ice sheet model VarGlaS

Brinkerhoff, D. J.; Johnson, J. V.

2013-07-01

We introduce a novel, higher order, finite element ice sheet model called VarGlaS (Variational Glacier Simulator), which is built on the finite element framework FEniCS. Contrary to standard procedure in ice sheet modelling, VarGlaS formulates ice sheet motion as the minimization of an energy functional, conferring advantages such as a consistent platform for making numerical approximations, a coherent relationship between motion and heat generation, and implicit boundary treatment. VarGlaS also solves the equations of enthalpy rather than temperature, avoiding the solution of a contact problem. Rather than include a lengthy model spin-up procedure, VarGlaS possesses an automated framework for model inversion. These capabilities are brought to bear on several benchmark problems in ice sheet modelling, as well as a 500 yr simulation of the Greenland ice sheet at high resolution. VarGlaS performs well in benchmarking experiments and, given a constant climate and a 100 yr relaxation period, predicts a mass evolution of the Greenland ice sheet that matches present-day observations of mass loss. VarGlaS predicts a thinning in the interior and thickening of the margins of the ice sheet.

Failure to transfer procedural skills learned in a laboratory to the bedside is commonly due to a lack of peer support/stimulation. A digital platform (Facebook) allows new clinical clerks to share experiences and tips that help augment their procedural skills in a peer-assisted learning/teaching method. This study aims to investigate the effectiveness of the innovation of using the digital platform to support the transfer of laboratory-trained procedural skills in the clinical units. Volunteer clinical clerks (n = 44) were enrolled into the peer-assisted learning (PAL) group, which was characterized by the peer-assisted learning of procedural skills during their final 3-month clinical clerkship block. Other clerks (n = 51) did not join the procedural skills-specific Facebook group and served as the self-directed learning regular group. The participants in both the PAL and regular groups completed pre- and post-intervention self-assessments for general self-assessed efficiency ratings (GSER) and skills specific self-assessed efficiency ratings (SSSER) for performing vein puncture, intravenous (IV) catheter and nasogastric (NG) tube insertion. Finally, all clerks received the post-intervention 3-station Objective Structured Clinical Skills Examination (OSCE) to test their proficiency for the abovementioned three procedural skills. Higher cumulative numbers of vein punctures, IV catheter insertions and NG tube insertions at the bedside were carried out by the PAL group than the regular group. A greater improvement in GSERs and SSSERs for medical procedures was found in the PAL group than in the regular group. The PAL group obtained higher procedural skills scores in the post-intervention OSCEs than the regular group. Our study suggested that the implementation of a procedural skill-specific digital platform effectively helps clerks to transfer laboratory-trained procedural skills into the clinical units. In comparison with the regular self-directed learning group, the peer-assisted learning characteristics of Facebook give additional benefits to the PAL group by enhancing their procedural skills.

Counting on fine motor skills: links between preschool finger dexterity and numerical skills.

Fischer, Ursula; Suggate, Sebastian P; Schmirl, Judith; Stoeger, Heidrun

2017-10-26

Finger counting is widely considered an important step in children's early mathematical development. Presumably, children's ability to move their fingers during early counting experiences to aid number representation depends in part on their early fine motor skills (FMS). Specifically, FMS should link to children's procedural counting skills through consistent repetition of finger-counting procedures. Accordingly, we hypothesized that (a) FMS are linked to early counting skills, and (b) greater FMS relate to conceptual counting knowledge (e.g., cardinality, abstraction, order irrelevance) via procedural counting skills (i.e., one-one correspondence and correctness of verbal counting). Preschool children (N = 177) were administered measures of procedural counting skills, conceptual counting knowledge, FMS, and general cognitive skills along with parent questionnaires on home mathematics and fine motor environment. FMS correlated with procedural counting skills and conceptual counting knowledge after controlling for cognitive skills, chronological age, home mathematics and FMS environments. Moreover, the relationship between FMS and conceptual counting knowledge was mediated by procedural counting skills. Findings suggest that FMS play a role in early counting and therewith conceptual counting knowledge. © 2017 John Wiley & Sons Ltd.

The Basic Surgical Skills course uses an assessment score interval of 0-3. An extended score interval, 1-6, was proposed by the Swedish steering committee of the course. The aim of this study was to analyze the trainee scores in the current 0-3 scored version compared to a proposed 1-6 scored version. Sixteen participants, seven females and nine males, were evaluated in the current and proposed assessment forms by instructors, observers, and learners themselves during the first and second day. In each assessment form, 17 tasks were assessed. The inter-rater reliability between the current and the proposed score sheets were evaluated with intraclass correlation (ICC) with 95% confidence intervals (CI). The distribution of scores for 'knot tying' at the last time point and 'bowel anastomosis side to side' given by the instructors in the current assessment form showed that the highest score was given in 31 and 62%, respectively. No ceiling effects were found in the proposed assessment form. The overall ICC between the current and proposed score sheets after assessment by the instructors increased from 0.38 (95% CI 0.77-0.78) on Day 1 to 0.83 (95% CI 0.51-0.94) on Day 2. A clear ceiling effect of scores was demonstrated in the current assessment form, questioning its validity. The proposed score sheet provides more accurate scores and seems to be a better feedback instrument for learning technical surgical skills in the Basic Surgical Skills course.

Educational graduates should have good competencies to compete in the 21st century. Integrated learning is a good way to develop competence of students in this century. Besides that, literacy skills are very important for students to get success in their learning and daily life. For this reason, integrated science learning and literacy skills are important in 2013 curriculum. However, integrated science learning and integration of literacy in learning can’t be implemented well. Solution of this problem is to develop adaptive contextual learning model by integrating digital age literacy. The purpose of the research is to determine the effectiveness of adaptive contextual learning model to improve competence of grade VIII students in junior high school. This research is a part of the research and development or R&D. Research design which used in limited field testing was before and after treatment. The research instruments consist of three parts namely test sheet of learning outcome for assessing knowledge competence, observation sheet for assessing attitudes, and performance sheet for assessing skills of students. Data of student’s competence were analyzed by three kinds of analysis, namely descriptive statistics, normality test and homogeneity test, and paired comparison test. From the data analysis result, it can be stated that the implementation of adaptive contextual learning model of integrated science by integrating digital age literacy is effective to improve the knowledge, attitude, and literacy skills competences of grade VIII students in junior high school at 95% confidence level.

Hand-drawn and lettered `Weekly Information Sheets' (WIS) were created on a weekly basis for an upper-level Sedimentology & Stratigraphy class. Use of these sheets resulted in improved work quality, attention to detail, communication skills, and overall engagement. The sheets were modeled on the work of Lynda Barry (https://www.drawnandquarterly.com/syllabus), and included a series of repeated elements: goofy/absurd newspaper clippings, marginally pertinent cartoon(s), a summary of the weeks activities / goals and lectures, as well as cartoon cat, mouse and penguin drawings with innane comments, quotes and general class reminders. The pedagogical aims for these weekly sheets were multifold. First, they were designed so that students could see the time and care I put in to the sheet - my hope was that this would show the time and care I expected them to put in to their work. Second, I wanted to create something students would take the time to read - despite this being a 400-level class, students are rarely diligent about reading a typewritten handout. Third, I wanted to have a vehicle for engaging them in the larger world, including ethical or moral dilemmas. Fourth, I wanted the students to reflectively consider the nature of communication in science. Finally, I wanted a mechanism to focus my thoughts on the teaching and learning for the upcoming week that went beyond simply reviewing my notes and activities. Student response to the WIS was positive; they read them, used them for organizing their class notes and exam review. Students arrived early for class on Mondays for the WIS - although I needed to give them time to read the sheet. Comparison with previous course offerings shows improvements in student communication skills (written reports, poster presentation) and overall achievement.

The Global Ice Sheet Mapping Orbiter (GISMO) mission was developed to address scientific needs to understand the polar ice subsurface structure. This NASA Instrument Incubator Program project is a collaboration between Ohio State University, the University of Kansas, Vexcel Corporation and NASA. The GISMO design utilizes an interferometric SAR (InSAR) strategy in which ice sheet reflected signals received by a dual-antenna system are used to produce an interference pattern. The resulting interferogram can be used to filter out surface clutter so as to reveal the signals scattered from the base of the ice sheet. These signals are further processed to produce 3D-images representing basal topography of the ice sheet. In the past three years, the GISMO airborne field campaigns that have been conducted provide a set of useful data for studying geophysical properties of the Greenland ice sheet. While topography information can be obtained using interferometric SAR processing techniques, ice sheet roughness statistics can also be derived by a relatively simple procedure that involves analyzing power levels and the shape of the radar impulse response waveforms. An electromagnetic scattering model describing GISMO impulse responses has previously been proposed and validated. This model suggested that rms-heights and correlation lengths of the upper surface profile can be determined from the peak power and the decay rate of the pulse return waveform, respectively. This presentation will demonstrate a procedure for estimating the roughness of ice surfaces by fitting the GISMO impulse response model to retrieved waveforms from selected GISMO flights. Furthermore, an extension of this procedure to estimate the scattering coefficient of the glacier bed will be addressed as well. Planned future applications involving the classification of glacier bed conditions based on the derived scattering coefficients will also be described.

2017-05-01

In current medical curricula, the transfer of procedural skills has received increasing attention. Skills lab learning and tutor-led teaching have become an inherent part of all medical curricula at German medical faculties. In 2011, the initial basis for the classification of clinical skills in medical school was created by the German Association for Medical Education (GMA) Committee's consensus statement on procedural skills. As a recommendation for medical curricula, the National Competency-based Catalogue of Learning Objectives (NKLM, 2015) lists procedural skills according to their curriculum integration and competency level. However, classification in regard to the perceived complexity, relevance, or teaching competency is still lacking. The present study aimed to investigate procedural skills taught at the Medical Faculty of Heidelberg in regard to their complexity, relevance, and required teaching skills. To achieve this aim (1) the specific procedural skills in terms of complexity, that is, the degree of difficulty, and (2) the perceived relevance of taught procedural skills for studying and subsequent medical profession as well as (3) the personal preparation and required teaching skills were assessed in medical teachers, tutors and students. During the winter semester 2014/2015, the evaluations of all medical teachers, student tutors, and medical students in the skills lab teaching departments of internal medicine, surgery, pediatrics, gynecology, and otorhinolaryngology at the Medical Faculty of Heidelberg were assessed via a quantitative cross-sectional questionnaire survey using 7-point Likert scales. The questionnaire comprised four item sets concerning 1) demographic details, 2) procedural skill complexity, 3) practical relevance, and 4) required preparation and teaching skills. Descriptive, quantitative analysis was used for questionnaire data. The survey included the data from 17 of 20 physicians (return rate: 85 %), 10 of 10 student tutors (return rate: 100 %) and a total of 406 of 691 students (return rate: 58.8 %). In terms of complexity and relevance, no major differences between medical teachers, tutors, and students were found. Procedural skills, assigned to the competence level of final year medical education in the NKLM, were also perceived as more complex than other skills. All skills were considered equally relevant, and student tutors were seen to have equally competent teaching skills as experienced medical teachers. This study largely underpins the NKLM's classification of procedural skills. The complexity assessment allows for conclusions to be drawn as to which skills are perceived to require particularly intensive training. Finally, our study corroborates extant findings that student tutors are apt at teaching procedural skills if they have been properly trained. Copyright © 2017. Published by Elsevier GmbH.

Syringe swap is an important problem in anesthetic care, causing harm to patients. We examined the effect of colored syringe and a colored sheet on the incidence of syringe swaps during anesthetic management. We determined the color code. The blue-syringe contains local anesthetics; yellow-syringe, sympathomimetic drugs; and white-syringe with a red label fixed opposite the scale, muscle relaxants. The colored sheet displays the photographs of the syringe with drug name, dose and volume. The colored syringe and colored sheet were supplied for use from February 2004. We compared the incidence of syringe swaps during the period from February 2004 to January 2005 with that from February 2003 to January 2004. Although five syringe swaps were recorded from February 2003 to January 2004, in 5901 procedures, we encountered no syringe swaps from February 2004 to January 2005, in 6078 procedures. The colored syringe and colored sheet significantly decreased the incidence of syringe swaps during anesthetic management (P <0.05). The use of the sheet together with colored syringes can prevent syringe swaps during anesthesia.

Procedural learning can acquire or develop skills through performance and repetition of a task unconsciously or unintentionally. Procedural skills are considered as the cornerstone in the neuropsychological rehabilitation to promote the autonomy of patients with brain damage, as those with Alzheimer's disease. This review presents data about procedural skills in Alzheimer's disease. Over the past three decades, we have found 40 articles studying various procedural skills in the Alzheimer's disease: motor, perceptual-motor, cognitive, perceptual-cognitive and those developed through serial reaction-time paradigm. We analyzed every study evaluating a procedural skill, indicating the used task and preservation or no preservation of procedural learning. Overall, most of the papers published describe conservation of learning procedures or relatively conserved in Alzheimer's disease, which could be used to promote patient autonomy.

To ensure patient safety, it is important to regularly assess the knowledge and practical skills of anesthesia trainees. This study was conducted to evaluate the competency of the residents and the impact of various corrective measures in the form of didactic lectures and clinical skill demonstrations on the conduct of various procedural skills by the residents. Ninety-five junior residents were enrolled in this study. Assessment of competency of 1 st , 2 nd , and 3 rd year residents in performing various procedure skills of anesthesia was done in two stages using procedure specific checklist (PSC) and Global Rating Scales (GRSs). Preliminary results of the first assessment (Score 1) were discussed with the residents; deficiencies were identified and corrective measures suggested by didactic lectures and clinical skill demonstrations which were followed by a subsequent assessment after 3 months (Score 2). There was a statistically significant improvement in the PSC and GRS scores after corrective measures for all the procedural interventions studied. Percentage increase in scores was maximum in 1 st year (42.98 ± 6.62) followed by 2 nd year (34.62 ± 5.49) and minimum in 3 rd year residents (18.06 ± 3.69). The percentage increase of scores was almost similar for all subset of procedural skills; low, intermediate, and high skill anesthetic procedures. For assessment of procedural skills of residents, use of PSC and GRS scores should be incorporated and the same should be used to monitor the impact of various corrective measures (didactic lectures and clinical skill demonstrations) on the conduct of various procedural skills by the resident.

Learning in the current 2013 curriculum is based on contextual issues based on questions that can encourage students to think broadly. HOTS is a real-life based assessment of everyday life, but in practice, the students are having trouble completing the HOTS issue. Learning difficulty is also influenced by personality type Based on the fact that the real difference one can see from a person is behavior. Kersey classifies the personality into 4 types, namely Idealist, Rational, Artisan, and Guardian. The researcher focuses on the type of guardian personality that is the type of personality that does not like the picture. This study aims to describe the difficulty of learning mathematics in students with a type of guardian personality in the completion of Geometry materials especially in solving HOTS. This research type is descriptive qualitative research. Instruments used in this study were the researchers themselves, personality class test sheets, learning difficulty test sheets in the form of HOTS Geometry test, and interview guides. The results showed that students with guardian personality it was found that a total of 3.37 % difficulties of number fact skill, 4.49 % difficulties of arithmetics skill, 37.08 % difficulties of information skill, 31.46% difficulties of language skill, 23.60 % difficulties of visual-spatial skill.

Recent data do not exist on medical students' performance of and attitudes toward procedural and interpretive skills deemed important by medical educators. A total of 171 medical students at seven medical schools were surveyed regarding frequency of performance, self-confidence, and perceived importance of 21 procedural and interpretive skills. Of the 122 responding students (71% response rate), a majority had never performed lumbar puncture, thoracentesis, paracentesis, or blood culture, and students reported lowest self-confidence in these skills. At least one-quarter of students had never performed phlebotomy, peripheral intravenous catheter insertion, or arterial blood sampling. Students perceived all 21 skills as important to learn and perform during medical school. Through the third year of medical school, a majority of students had never performed important procedures, and a substantial minority had not performed basic procedures. Students had low self-confidence in skills they rarely performed, but perceived all skills surveyed as important.

Development of explosive welding procedures to fabricate channeled nozzle structures

NASA Technical Reports Server (NTRS)

Pattee, H. E.; Linse, V. D.

1976-01-01

Research was conducted to demonstrate the feasibility of fabricating a large contoured structure with complex internal channeling by explosive welding procedures. Structures or nozzles of this nature for wind tunnel applications were designed. Such nozzles vary widely in their complexity. However, in their simplest form, they consist of a grooved base section to which a cover sheet is attached to form a series of internal cooling passages. The cover sheet attachment can be accomplished in various ways: fusion welding, brazing, and diffusion welding. The cover sheet has also been electroformed in place. Of these fabrication methods, brazing has proved most successful in producing nozzles with complex contoured surfaces and a multiplicity of internal channels.

One-year retention of general and sequence-specific skills in a probabilistic, serial reaction time task.

PubMed

Romano, Jennifer C; Howard, James H; Howard, Darlene V

2010-05-01

Procedural skills such as riding a bicycle and playing a musical instrument play a central role in daily life. Such skills are learned gradually and are retained throughout life. The present study investigated 1-year retention of procedural skill in a version of the widely used serial reaction time task (SRTT) in young and older motor-skill experts and older controls in two experiments. The young experts were college-age piano and action video-game players, and the older experts were piano players. Previous studies have reported sequence-specific skill retention in the SRTT as long as 2 weeks but not at 1 year. Results indicated that both young and older experts and older non-experts revealed sequence-specific skill retention after 1 year with some evidence that general motor skill was retained as well. These findings are consistent with theoretical accounts of procedural skill learning such as the procedural reinstatement theory as well as with previous studies of retention of other motor skills.

Comprehensive Social Skills Taxonomy: Development and Application.

PubMed

Kauffman, Nancy A; Kinnealey, Moya

2015-01-01

We developed a comprehensive social skills taxonomy based on archived children's social skill goal sheets, and we applied the taxonomy to 6,897 goals of children in 6 diagnostic categories to explore patterns related to diagnosis. We used a grounded theory approach to code and analyze social skill goals and develop the taxonomy. Multivariate analysis of variance and Tukey post hoc honestly significant difference test were used to analyze differences in social skill needs among diagnostic groups. We developed a taxonomy of 7 social skill constructs or categories, descriptions, and behavioral indicators. The 7 social skill categories were reflected across 6 diagnostic groups, and differences in social skill needs among groups were identified. This comprehensive taxonomy of social skills can be useful in developing research-based individual, group, or institutional programming to improve social skills.

Procedural skills are a significant component of clinical practice. Doctors, nurses, midwives and paramedics are trained to use a variety of procedural skills. Rural clinicians in particular are often required to maintain competence in some procedural skills that are used infrequently, and which may require regular and repeated rehearsal. This paper reports on a research project conducted in Gippsland, Victoria, to ascertain the frequency of use, and relevance to clinical practice, of a range of skills in the fields of medicine, nursing, midwifery, and paramedic practice. The project also gathered data on the attitudes of clinicians regarding how frequently and by what means they thought they needed to practice these skills with a particular focus on the use of simulation as an educational method. The research was conducted following identification of a specific set of procedural skills for each professional group. Skills were identified by an expert steering committee. We developed online questionnaires that consisted of two parts: 1) demographic and professional characteristics, and 2) experience of procedural skills and perceived training needs. We sought to invite all practicing clinicians (doctors, nurses, midwives, paramedics) working in Gippsland. Online surveys were distributed between November 2011 and April 2012 with three follow-up attempts. The Monash University Human Research Ethics Committee approved the study. Valid responses were received from 58 doctors, 94 nurses, 46 midwives, and 30 paramedics, whom we estimate to represent not more than 20% of current clinicians within these professions. This response rate reflected some of the difficulties experienced in the conduct of the research. Results were tabulated for each professional group across the range of skills. There was significant correlation between the frequency of certain skills and confidence with maintenance of these skills. This did not necessarily correlate with perceptions of respondents as to how often they need to practice each skill to maintain mastery. The more complex the skill, the more likely the respondents were to report a need for frequent rehearsal of the skill. There was variation between the professional groups as to how to retain mastery; for some skills, professional groups reported skill maintenance through clinical observation and clinical practice; for other skills, simulation was seen to be more appropriate. This project provided insight into the clinical application of procedural skills for clinicians comprising a relatively large professional population within a defined geographical region in rural Victoria, as well as attitudes to skills maintenance and competency. Although not the focus of the study, an unexpected outcome was the design of questionnaires on procedural skills. We believe that the questionnaires may have value in other rural settings. We acknowledge the limitations of the study in the text. The project provides some information on which to base planning for procedural skills education, including simulation-based training, and directions for further research.

Miltenberger, R G; Fuqua, R W

1985-01-01

Two procedures were used to teach behavioral assessment interviewing skills: a training manual and one-to-one instruction that included modeling, rehearsal, and feedback. Two graduate students and two advanced undergraduates were trained with each procedure. Interviewing skills were recorded in simulated assessment interviews conducted by each student across baseline and treatment conditions. Each training procedure was evaluated in a multiple baseline across students design. The results showed that both procedures were effective for training behavioral interviewing skills, with all students reaching a level of 90%-100% correct responding. Finally, a group of experts in behavior analysis rated each interviewing skill as relevant to the conduct of an assessment interview and a group of behavioral clinicians socially validated the outcomes of the two procedures.

To introduce a novel modified surgical procedure of excision of anterior cartilage of the pseudocyst along with plastic sheet compression for the treatment of auricular pseudocyst and ascertain the effect of the surgical modality of this disease. A retrospective study. Medical college hospital. Eighty-seven auricular pseudocyst patients were subjected to excision of the anterior cartilage of the pseudocyst followed by plastic sheet compression from July 2006 to September 2013. The effects of the operation were evaluated. Eighty patients were males and 7 were females. The median age was 52 years old. The lesions of 86 patients were unilateral and only 1 was bilateral. The clinical features presented a hemispheric painless swelling, which was seen on the ventral side of the auricle, usually the scaphoid and triangular fossa. The average major axis of the pseudocyst was 1.7 ± 0.6 cm. The patients underwent excision of anterior cartilage of the pseudocyst along with plastic sheet compression. The average follow-up period was 51.9 ± 19.1 months. No recurrence was observed with this technique, and the appearance of the auricle was cosmetically acceptable. Our novel modified surgical procedure of excision of anterior cartilage of pseudocyst along with plastic sheet compression is an effective surgical management for the auricular pseudocyst. The advantages of a simple technique, a short-term therapeutic period, and no recurrence made the surgical procedure worth recommending as the definitive treatment of auricular pseudocysts. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

Tools used to assess medical students competence in procedural skills at the end of a primary medical degree: a systematic review.

Morris, Marie C; Gallagher, Tom K; Ridgway, Paul F

2012-01-01

The objective was to systematically review the literature to identify and grade tools used for the end point assessment of procedural skills (e.g., phlebotomy, IV cannulation, suturing) competence in medical students prior to certification. The authors searched eight bibliographic databases electronically - ERIC, Medline, CINAHL, EMBASE, Psychinfo, PsychLIT, EBM Reviews and the Cochrane databases. Two reviewers independently reviewed the literature to identify procedural assessment tools used specifically for assessing medical students within the PRISMA framework, the inclusion/exclusion criteria and search period. Papers on OSATS and DOPS were excluded as they focused on post-registration assessment and clinical rather than simulated competence. Of 659 abstracted articles 56 identified procedural assessment tools. Only 11 specifically assessed medical students. The final 11 studies consisted of 1 randomised controlled trial, 4 comparative and 6 descriptive studies yielding 12 heterogeneous procedural assessment tools for analysis. Seven tools addressed four discrete pre-certification skills, basic suture (3), airway management (2), nasogastric tube insertion (1) and intravenous cannulation (1). One tool used a generic assessment of procedural skills. Two tools focused on postgraduate laparoscopic skills and one on osteopathic students and thus were not included in this review. The levels of evidence are low with regard to reliability - κ = 0.65-0.71 and minimum validity is achieved - face and content. In conclusion, there are no tools designed specifically to assess competence of procedural skills in a final certification examination. There is a need to develop standardised tools with proven reliability and validity for assessment of procedural skills competence at the end of medical training. Medicine graduates must have comparable levels of procedural skills acquisition entering the clinical workforce irrespective of the country of training.

2017-12-01

Teaching about climate and climate change is conceptually challenging. While teaching tools and lesson plans are rapidly evolving to help teachers and students improve their understanding of climate processes, there are very few tools targeting ice sheet and glacier dynamics. We have built an interactive ice sheet model that allows students to explore how Antarctic glaciers respond to different climate perturbations. Interactive models offer advantages that are hard to obtain in traditional classroom settings; users can systematically investigate hypothetical situations, explore the effects of modifying systems, and repeatedly observe how systems interrelate. As a result, this project provides a much-needed bridge between the data and models used by the scientific community and students in high school and college. We target our instructional and assessment activities to three high school and college students with the overall aim of increasing understanding of ice sheet dynamics and the different ways that ice sheets are impacted by climate change, while also improving their fundamental math skills.

2017-04-01

The entrustable professional activity (EPA) framework has been identified as a useful approach to assessment in competency-based education. To apply an EPA framework for assessment, essential skills necessary for entrustment to occur must first be identified. Using an EPA framework, our study sought to (1) define the essential skills required for entrustment for 7 bedside procedures expected of graduates of Canadian internal medicine (IM) residency programs, and (2) develop rubrics for the assessment of these procedural skills. An initial list of essential skills was defined for each procedural EPA by focus groups of experts at 4 academic centers using the nominal group technique. These lists were subsequently vetted by representatives from all Canadian IM training programs through a web-based survey. Consensus (more than 80% agreement) about inclusion of each item was sought using a modified Delphi exercise. Qualitative survey data were analyzed using a framework approach to inform final assessment rubrics for each procedure. Initial lists of essential skills for procedural EPAs ranged from 10 to 24 items. A total of 111 experts completed the national survey. After 2 iterations, consensus was reached on all items. Following qualitative analysis, final rubrics were created, which included 6 to 10 items per procedure. These EPA-based assessment rubrics represent a national consensus by Canadian IM clinician educators. They provide a practical guide for the assessment of procedural skills in a competency-based education model, and a robust foundation for future research on their implementation and evaluation.

2009-07-01

To compare the effects of the Sirius rescue sheet with gel pads versus gel pads alone on intraoperative body temperature in dogs less than 10 kg. Forty small breed dogs undergoing elective surgical procedures were randomly assigned to two groups. One group was intraoperatively laid on warmed gel pads, and the other group was additionally wrapped in a Sirius rescue sheet. Oesophageal body temperature was determined every 10 minutes and compared between groups. Temperature of gel pads was measured preoperatively and postoperatively to compare heat loss of the gel pads between groups. The body temperature of dogs wrapped with the Sirius rescue sheet increased intraoperatively. In dogs just lying on warmed gel pads, a decrease in mean body temperature was revealed and mean body temperatures differed between groups after 40 minutes. Extent of heat loss from the gel pads did not differ between the groups. The Sirius rescue sheet, used in addition to warmed gel pads, led to higher intraoperative body temperatures in small breed dogs undergoing surgical procedures to the extremities and the head. The cost-effectiveness and ease of handling make this a useful addition to clinical practice.

Novel approaches for faculty development and assessment of procedural teaching skills are needed to improve the procedural education of trainees. The Objective Structured Teaching Exercise (OSTE) entails a simulated encounter in which faculty are observed teaching a standardized student and has been used to evaluate teaching skills. Use of an OSTE to assess the teaching of central venous catheterization has not been reported. The purpose of this study was to develop a procedural OSTE for subclavian central venous catheter (CVC) insertion and to determine specific aspects of procedural teaching associated with improved skills in novices. Critical care faculty/fellows taught a standardized student to insert a CVC in a simulator. We assessed the instructor's teaching skills using rating scales to generate a procedural teaching score. After this encounter, the instructor taught novice medical students to place CVCs in simulators. Novices then independently placed catheters in simulators and were evaluated by trained observers using a checklist. Generalized estimating equations were used to examine the correlation between specific teaching behaviors and the novices' skills in CVC placement. We recruited 10 participants to serve as teachers and 30 preclinical medical students to serve as novice learners. The overall mean procedural teaching score was 85.5 (±15.4). Improved student performance was directly related to the degree to which the teacher "provided positive feedback" (β = 1.53, SE = 0.44, P = 0.001), "offered learner suggestions for improvement" (β = 1.40, SE = 0.35, P < 0.001), and "demonstrated the procedure in a step-by-step manner" (β = 2.50, SE = 0.45, P < 0.001). There was no significant correlation between total scores and student skills (β = 0.06, SE = 0.46, P = 0.18). The OSTE is a standardized method to assess procedural teaching skills. Our findings suggest that specific aspects of procedural teaching should be emphasized to ensure effective transfer of psychomotor skills to trainees.

The present study examined the moderating effects of procedural and distributive justice on the relationships between political skill and task performance and organizational citizenship behavior (OCB) among 175 supervisor-subordinate dyads of a government organization. Using Mischel's (1968) situationist perspective, high justice conditions were considered "strong situations," whereas low justice conditions were construed as "weak situations." We found that when both procedural and distributive justice were low, political skill was positively related to performance. Under conditions of both high procedural and high distributive justice, political skill was negatively related to performance. Finally, under conditions of low distributive justice, political skill was positively related to OCB, whereas under conditions of high distributive justice, political skill had little effect on OCB. These results highlight the importance of possessing political skill in weak but not strong situations.

Garrison Clinical Setting Inadequate for Maintenance of Procedural Skills for Emergency Medicine Physicians: A Cross-Sectional Study.

PubMed

Schauer, Steven G; Varney, Shawn M; Cox, Kristin L

2015-01-01

Emergency medicine physicians (EPs) are often placed in far-forward, isolated areas in theater. Maintenance of their emergency intervention skills is vital to keep the medical forces deployment ready. The US Army suggests that working at a Military Treatment Facility (MTF) is sufficient to keep emergency procedural skills at a deployment-ready level. We sought to compare the volume of emergency procedures that providers reported necessary to maintain their skills with the number available in the MTF setting. EPs were surveyed to quantify the number of procedures they reported they would need to perform yearly to stay deployment-ready. We obtained procedure data for their duty stations and compared the procedure volume with the survey responses to determine if working at an MTF is sufficient to keep providers' skills deployment ready. The reported necessary average numbers per year were as follows: tube thoracostomy (5.9), intubation (11.4), cricothyrotomy (4.2), lumbar puncture (5.2), central line (10.0), focused assessment with sonography for trauma (FAST) (21.3), reductions (10.6), splints (10.5), and sedations (11.7). None of the procedure volumes at MTFs met provider requirements with the exception of FAST examinations at the only trauma center. This suggests the garrison clinical environment is inadequate for maintaining procedure skills. Further research is needed to determine modalities that will provide adequate training volume. 2015.

Incorporation of ice sheet models into an Earth system model: Focus on methodology of coupling

2018-03-01

Elaboration of a modern Earth system model (ESM) requires incorporation of ice sheet dynamics. Coupling of an ice sheet model (ICM) to an AOGCM is complicated by essential differences in spatial and temporal scales of cryospheric, atmospheric and oceanic components. To overcome this difficulty, we apply two different approaches for the incorporation of ice sheets into an ESM. Coupling of the Antarctic ice sheet model (AISM) to the AOGCM is accomplished via using procedures of resampling, interpolation and assigning to the AISM grid points annually averaged meanings of air surface temperature and precipitation fields generated by the AOGCM. Surface melting, which takes place mainly on the margins of the Antarctic peninsula and on ice shelves fringing the continent, is currently ignored. AISM returns anomalies of surface topography back to the AOGCM. To couple the Greenland ice sheet model (GrISM) to the AOGCM, we use a simple buffer energy- and water-balance model (EWBM-G) to account for orographically-driven precipitation and other sub-grid AOGCM-generated quantities. The output of the EWBM-G consists of surface mass balance and air surface temperature to force the GrISM, and freshwater run-off to force thermohaline circulation in the oceanic block of the AOGCM. Because of a rather complex coupling procedure of GrIS compared to AIS, the paper mostly focuses on Greenland.

Simulation allows educators to develop learner-focused training and outcomes-based assessments. However, the effectiveness and validity of simulation-based training in emergency medicine (EM) requires further investigation. Teaching and testing technical skills require methods and assessment instruments that are somewhat different than those used for cognitive or team skills. Drawing from work published by other medical disciplines as well as educational, behavioral, and human factors research, the authors developed six research themes: measurement of procedural skills; development of performance standards; assessment and validation of training methods, simulator models, and assessment tools; optimization of training methods; transfer of skills learned on simulator models to patients; and prevention of skill decay over time. The article reviews relevant and established educational research methodologies and identifies gaps in our knowledge of how physicians learn procedures. The authors present questions requiring further research that, once answered, will advance understanding of simulation-based procedural training and assessment in EM.

2016-06-01

Resident programs must assess residents' achievement of core competencies for clinical and procedural skills. Video-augmented feedback may facilitate procedural skill acquisition and promote more accurate self-assessment. A randomized controlled study to investigate whether video-augmented verbal feedback leads to increased procedural skill and improved accuracy of self-assessment compared to verbal only feedback. Participants were evaluated during procedural training for ultrasound guided internal jugular central venous catheter (US IJ CVC) placement. All participants received feedback based on a validated 30-point checklist for US IJ CVC placement and validated 6-point procedural global rating scale. Scores in both groups improved by a mean of 9.6 points (95% CI: 7.8-11.4) on the 30-point checklist, with no difference between groups in mean score improvement on the global rating scale. In regards to self-assessment, participant self-rating diverged from faculty scoring, increasingly so after receiving feedback. Residents rated highly by faculty underestimated their skill, while those rated more poorly demonstrated increasing overestimation. Accuracy of self-assessment was not improved by addition of video. While feedback advanced the skill of the resident, video-augmented feedback did not enhance skill acquisition or improve accuracy of resident self-assessment compared to standard feedback.

Social media has become increasingly important over the past decades and has been integrated in various environments, including the healthcare setting. Yet, the influence of social media use on the social skills and nurse-patient interaction of nurses is an area in nursing that requires further studies. This study determined the interrelationships among social media use profile, social skills, and nurse-patient interaction of Registered Nurses in tertiary hospitals. Employing structural equation modeling, a descriptive-correlational study was conducted among 212 consecutively-selected nurses from two tertiary hospitals. Consenting respondents completed a two-part survey composed of the respondent profile sheet and the Social Skills Inventory. The respondent profile sheet assessed demographic profile and social media use profile in terms of the mode, frequency, and duration of utilization. Three trained team members observed each nurse-patient dyad and completed the Nurse-Patient Bonding Instrument. A good fit model illustrated the negative effects of frequent social media use to patient openness (β = -0.18, p < 0.05) and engagement (β = -0.11, p ≤ 0.05). Longer use of social media on a daily basis, however, positively affected both dimensions of social skills. Accessing social media platforms using non-handheld devices showed the most influential positive effects to social skills and nurse-patient interaction. Additionally, although verbal social skills positively affected most dimensions of nurse-patient interaction, non-verbal social skills negatively influenced patient engagement (β = -0.19, p = 0.019) and nurse openness (β = -0.38, p ≤ 0.05). The structural model illustrates the effects of using social media on the social skills and nurse-patient interaction of nurses and emphasizes the need for implementing institutional policies on the judicious use and application of social media in the workplace. Further, social skills development programs geared toward having a balanced social skill must be implemented. Copyright © 2018 Elsevier Ltd. All rights reserved.

1981-01-01

It is pointed out that activities in recent years directed towards reduction in the cost of silicon solar cells for terrestrial photovoltaic applications have resulted in impressive advancements in the area of silicon sheet formation from melt. The techniques used in the process of sheet formation can be divided into two general categories. All approaches in one category require subsequent ingot wavering. The various procedures of the second category produce silicon in sheet form. The performance of baseline solar cells is discussed. The baseline process included identification marking, slicing to size, and surface treatment (etch-polishing) when needed. Attention is also given to the performance of cells with process variations, and the effects of sheet quality on performance and processing.

Various film characterization procedures, including classical metallography, SEM analyses, X ray diffraction analyses, surface profilometry, and electrical measurements (resistivity, carrier concentration, mobility, spreading resistance profiles, and minority-carrier lifetime by the C-V-t method) area used to correlate Si sheet properties with CVD parameters and substrate properties. Evaluation procedures and measurements are given. Experimental solar cell structures were made both in epitaxial Si sheet (on sapphire substrates) and in polycrystalline material on alumina substrates, the former to provide an indication of what might be an upper limit on performance of the latter. Preliminary results are given, as obtained in cell structures not specially designed to allow for the unique properties of the sheet material, and fabricated in material known to be far from optimum for photovoltaic performance. Low power conversion efficiencies have been obtained in the epitaxial as well as the polycrystalline Si sheet.

1990-01-01

The rapid solidification of aluminum alloys as powder and the subsequent fabrication processes can be used to develop and tailor alloys to satisfy specific aerospace design requirements, including high strength and toughness. Laboratory procedures to produce aluminum powder-metallurgy (PM) materials are efficient but require evidence that the laboratory methods used can produce a product with superior properties. This paper describes laboratory equipment and procedures which can be used to produce tough aluminum PM sheet. The processing of a 2124 + 0.9 percent Zr aluminum alloy powder is used as an example. The fully hardened sheet product is evaluated in terms of properties and microstructure. The key features of the vacuum hot press pressing operation used to consolidate the powder are described. The 2124 + 0.9 percent Zr - T8 temper aluminum sheet produced was both strong (460-490 MPa yield strength) and tough (Kahn Tear unit-propagation- energy values over three times those typical for ingot metallurgy 2024-T81). Both the longitudinal and longitudinal-transverse directions of the sheet were tested. The microstructure was well refined with subgrains of one or two micrometers. Fine dispersoids of Al3Zr in the precipitate free regions adjacent to boundaries are believed to contribute to the improved toughness.

Recent data do not exist regarding fourth-year medical students' performance of and attitudes toward procedural and interpretive skills, and how these differ from third-year students'. Cross-sectional survey conducted in February 2006 of 122 fourth-year students from seven U.S. medical schools, compared with their responses in summer 2005. Students estimated their cumulative performance of 22 skills and reported self-confidence and perceived importance using a five-point Likert-type scale. The response rate was 79% (96/122). A majority reported never having performed cardioversion, thoracentesis, cardiopulmonary resuscitation, blood culture, purified protein derivative placement, or paracentesis. One fifth of students had never performed peripheral intravenous catheter insertion, phlebotomy, or arterial blood sampling. Students reported increased cumulative performance of 17 skills, increased self-confidence in five skills, and decreased perceived importance in three skills (two-sided P < .05). A majority of fourth-year medical students still have never performed important procedures, and a substantial minority have not performed basic procedures.

Saxon, Kathleen D; Kapadia, Alison P R; Juneja, Nadia S; Bassin, Benjamin S

2014-03-01

Teaching emergency procedural skills in a wilderness setting can be logistically challenging. To teach these skills as part of a wilderness medicine elective for medical students, we designed an outdoor simulation session with low-fidelity models. The session involved 6 stations in which procedural skills were taught using homemade low-fidelity simulators. At each station, the students encountered a "victim," who required an emergency procedure that was performed using the low-fidelity model. The models are easy and inexpensive to construct, and their design and implementation in the session is described here. Using low-fidelity simulation models in an outdoor setting is an effective teaching tool for emergency wilderness medicine procedures and can easily be reproduced in future wilderness medicine courses. © 2014 Wilderness Medical Society Published by Wilderness Medical Society All rights reserved.

Maintaining trauma-specific surgical skills is an ongoing challenge for surgical training programs. An objective assessment of surgical skills is needed. We hypothesized that a validated surgical performance assessment tool could detect differences following a training intervention. We developed surgical performance assessment metrics based on discussion with expert trauma surgeons, video review of 10 experts and 10 novice surgeons performing three vascular exposure procedures and lower extremity fasciotomy on cadavers, and validated the metrics with interrater reliability testing by five reviewers blinded to level of expertise and a consensus conference. We tested these performance metrics in 12 surgical residents (Year 3-7) before and 2 weeks after vascular exposure skills training in the Advanced Surgical Skills for Exposure in Trauma (ASSET) course. Performance was assessed in three areas as follows: knowledge (anatomic, management), procedure steps, and technical skills. Time to completion of procedures was recorded, and these metrics were combined into a single performance score, the Trauma Readiness Index (TRI). Wilcoxon matched-pairs signed-ranks test compared pretraining/posttraining effects. Mean time to complete procedures decreased by 4.3 minutes (from 13.4 minutes to 9.1 minutes). The performance component most improved by the 1-day skills training was procedure steps, completion of which increased by 21%. Technical skill scores improved by 12%. Overall knowledge improved by 3%, with 18% improvement in anatomic knowledge. TRI increased significantly from 50% to 64% with ASSET training. Interrater reliability of the surgical performance assessment metrics was validated with single intraclass correlation coefficient of 0.7 to 0.98. A trauma-relevant surgical performance assessment detected improvements in specific procedure steps and anatomic knowledge taught during a 1-day course, quantified by the TRI. ASSET training reduced time to complete vascular control by one third. Future applications include assessing specific skills in a larger surgeon cohort, assessing military surgical readiness, and quantifying skill degradation with time since training.

Medical students' ability to learn clinical procedures and competently apply these skills is an essential component of medical education. Complex skills with limited opportunity for practice have been shown to degrade without continued refresher training. To our knowledge there is no evidence that objectively evaluates temporal degradation of clinical skills in undergraduate medical education. The purpose of this study was to evaluate temporal retention of clinical skills among third year medical students. This was a cross-sectional study conducted at four separate time intervals in the cadaver laboratory at a public medical school. Forty-five novice third year medical students were evaluated for retention of skills in the following three procedures: pigtail thoracostomy, femoral line placement, and endotracheal intubation. Prior to the start of third-year medical clerkships, medical students participated in a two-hour didactic session designed to teach clinically relevant materials including the procedures. Prior to the start of their respective surgery clerkships, students were asked to perform the same three procedures and were evaluated by trained emergency medicine and surgery faculty for retention rates, using three validated checklists. Students were then reassessed at six week intervals in four separate groups based on the start date of their respective surgical clerkships. We compared the evaluation results between students tested one week after training and those tested at three later dates for statistically significant differences in score distribution using a one-tailed Wilcoxon Mann-Whitney U-test for non-parametric rank-sum analysis. Retention rates were shown to have a statistically significant decline between six and 12 weeks for all three procedural skills. In the instruction of medical students, skill degradation should be considered when teaching complex technical skills. Based on the statistically significant decline in procedural skills noted in our investigation, instructors should consider administering a refresher course between six and twelve weeks from initial training.

To assess the current state of published literature on communication skills teaching in urology to inform future directions for research and teaching. Excellent patient-physician communication skills increase understanding of medical conditions, facilitate shared decision-making regarding treatment planning, improve clinical outcomes, and decrease lawsuits. Surgical and procedure-based subspecialties, including urology, have generally been slow to incorporate formal communication skills teaching into curricula for postgraduate trainees. We performed a PubMed literature search using multiple keywords, selecting and reviewing articles published in English, and addressing 1 of 3 domains (curriculum development, teaching methods, and assessment methods) of communication skills teaching. The distribution of articles within the urology-specific literature was compared with that of procedure-based specialties as a whole. Eight articles were found in the urology literature, and 24 articles were found in other procedure-based specialties. Within the urology-specific literature, all 8 articles (100%) acknowledged the need for communication curriculum development, 1 article (12.5%) described how communication skills were taught, and 1 article (12.5%) discussed how communication skills were assessed. Fewer articles in other procedure-based specialties acknowledged the need to develop curricula (29.2%, P = .0007) but were equally likely to discuss communication skills teaching (37.5%, P = .63) and assessment (33.3%, P = .73). Orthopedic surgery is the only surgical subspecialty with ongoing, adaptable, formal training for physicians. Most current publications addressing communication skills in procedure-based specialties are specialty specific and focus on only 1 of the 3 communication domains. Opportunities exist to share information and to create more integrated models to teach communication skills in urology. Copyright © 2018 Elsevier Inc. All rights reserved.

Large sheet-type surgical materials (e.g., absorbable hemostat, adhesion barrier membranes, and flat surgical mesh) are difficult to introduce into a corporeal cavity using a 5-mm trocar; however, laparoscopic surgeries that use mainly 5-mm trocars are increasing. Furthermore, it is necessary not only to introduce but also to secure the applied surgical material and expand it from the original surgical site. To address these challenges, we developed a novel procedure for introducing such surgical materials into a corporeal cavity using a 5-mm trocar and a self-expanding origami structure, called the "chevron pleats procedure (CPP)". We used CPP in 114 cases of laparoscopic surgery for gastrointestinal diseases. The chevron folding pattern is an excellent origami structure and compactly folds a large sheet of material for use with a slim trocar. Surgical materials were folded using a chevron pleats pattern and inserted into a novel, slim, long syringe-type device, which was made from a specially ordered precision polypropylene tube, for introduction into a corporeal cavity. When the surgical material was used, the end of the device was placed above the surgical site and the inner rod was pushed. The surgical material was securely injected and expanded over the surgical site. Surgical materials were introduced smoothly and securely using a 5-mm trocar to a site of intraoperative bleeding, the incisional surface of the liver, and defects of the abdominal wall or peritoneum. Efficient hemostasis was attained, the introduction and expansion of surgical mesh was made simpler, and the covering of defects of the peritoneum with adhesion barrier membranes, which is typically difficult during laparoscopic surgery, was easily performed. CPP is a basic utility procedure for introducing several sheet-type surgical materials into a corporeal cavity with a 5-mm trocar and might help ensure efficient and safe laparoscopic surgery.

New method for obliterative treatment of an anterior wall aneurysm in the internal carotid artery: encircling silicone sheet clip procedure--technical case report.

2001-08-01

Aneurysms on the anterior surface of the internal carotid artery (ICA) have been shown to be somewhat different from ordinary berry aneurysms because they are rather small, grow rapidly in a short time, and easily lead to rupture, especially during surgery. The most difficult problem is that this type of aneurysm cannot be eliminated easily by an ordinary clipping procedure without causing apparent arterial stenosis or occlusion. A 52-year-old man experienced a subarachnoid hemorrhage because of a ruptured aneurysm located on the anterior surface of the ICA. The tiny aneurysmal body, which was covered with a layer of brain tissue, was successfully exposed. The ICA seemed to be atherosclerotic, and the aneurysmal portion was solitary and had a reddish color. A large silicone sheet encircling clip (Vascwrap; Mizuho Ikakogyo Co., Ltd., Tokyo, Japan) was selected for this patient. The proximal margin of the silicone sheet was incised with a V-shaped cut, and the middle part of the sheet, which covered the diagonal part of the ICA, was trimmed to make it shorter. The blade of the fenestrated clip was applied to obliterate the aneurysm and was attached to the normal arterial wall together with this modified Vascwrap sheet to create a small space between the normal arterial wall and the surrounding Vascwrap sheet. Then tiny pieces of Teflon fiber (E.I. duPont de Nemours and Co., Wilmington, DE) was inserted from both margins, and the whole Vascwrap sheet was sealed with fibrin glue to ensure good adhesion. This method seemed adequate in treating this difficult aneurysm without causing postoperative regrowth or occlusion of the patient's ICA.

This study aimed to investigate the improvement to pre-service teacher’s communication skills through Higher Order Thinking Laboratory (HOT Lab) on electric circuit topic. This research used the quasi-experiment method with pretest-posttest control group design. Research subjects were 60 students of Physics Education in UIN Sunan Gunung Djati Bandung. The sample was chosen by random sampling technique. Students’ communication skill data collected using a communication skills test instruments-essays form and observations sheets. The results showed that pre-service teacher communication skills using HOT Lab were higher than verification lab. Student’s communication skills in groups using HOT Lab were not influenced by gender. Communication skills could increase due to HOT Lab based on problems solving that can develop communication through hands-on activities. Therefore, the conclusion of this research shows the application of HOT Lab is more effective than the verification lab to improve communication skills of pre-service teachers in electric circuit topic and gender is not related to a person’s communication skills.

2015-04-01

The purpose of this study was to evaluate the effectiveness of a multifaceted simulation-based resident training for CT-guided fluoroscopic procedures by measuring procedural and technical skills, radiation dose, and procedure times before and after simulation training. A prospective analysis included 40 radiology residents and eight staff radiologists. Residents took an online pretest to assess baseline procedural knowledge. Second-through fourth-year residents' baseline technical skills with a procedural phantom were evaluated. First-through third-year residents then underwent formal didactic and simulation-based procedural and technical training with one of two interventional radiologists and followed the training with 1 month of supervised phantom-based practice. Thereafter, residents underwent final written and practical examinations. The practical examination included essential items from a 20-point checklist, including site and side marking, consent, time-out, and sterile technique along with a technical skills portion assessing pedal steps, radiation dose, needle redirects, and procedure time. The results indicated statistically significant improvement in procedural and technical skills after simulation training. For residents, the median number of pedal steps decreased by three (p=0.001), median dose decreased by 15.4 mGy (p<0.001), median procedure time decreased by 4.0 minutes (p<0.001), median number of needle redirects decreased by 1.0 (p=0.005), and median number of 20-point checklist items successfully completed increased by three (p<0.001). The results suggest that procedural skills can be acquired and improved by simulation-based training of residents, regardless of experience. CT simulation training decreases procedural time, decreases radiation dose, and improves resident efficiency and confidence, which may transfer to clinical practice with improved patient care and safety.

2007-10-01

We describe the use of a silicone elastomer sheet (SILASTIC) to prevent peridural fibrosis in patients who underwent a craniectomy and a subsequent cranioplasty. We performed a decompressive craniectomy and a subsequent cranioplasty with an autologous bone flap in 50 patients (mean age, 40 years) between 1996 and 2005 at our institution. Most of the craniectomies were performed as an emergency procedure for relief of brain swelling. The standard decompressive craniectomy technique that we performed included bone removal and a duroplasty in 26 of the 50 patients, however, a SILASTIC sheet was added to the standard decompressive craniectomy in the remaining patients in an attempt to prevent dural adhesions. The development of adhesion formation between the tissue layers was evaluated during the cranioplasty in terms of operative time and the amount of blood loss. During the cranioplasty, we observed that the SILASTIC sheet succeeded in creating a controlled dissection plane, which facilitated access to the epidural space, shortened the operative time by approximately 24.8% and diminished the intraoperative blood loss by 37.9% as compared with the group of patients who underwent the standard cranioplasty. These differences were statistically significant (p<0.05). The use of a SILASTIC sheet to prevent peridural scarring and to facilitate cranioplasty in patients who have previously undergone a craniectomy is a good technique, regardless of the procedural indication.

Detection of defects in formed sheet metal using medial axis transformation

NASA Astrophysics Data System (ADS)

Murmu, Naresh C.; Velgan, Roman

2003-05-01

In the metal forming processes, the sheet metals are often prone to various defects such as thinning, dents, wrinkles etc. In the present manufacturing environments with ever increasing demand of higher quality, detecting the defects of formed sheet metal using an effective and objective inspection system is the foremost norm to remain competitive in market. The defect detection using optical techniques aspire to satisfy its needs to be non-contact and fast. However, the main difficulties to achieve this goal remain essentially on the development of efficient evaluation technique and accurate interpretation of extracted data. The defect like thinning is detected by evaluating the deviations of the thickness in the formed sheet metal against its nominal value. The present evaluation procedure for determination of thickness applied on the measurements data is not without deficiency. To improve this procedure, a new evaluation approach based on medial axis transformation is proposed here. The formed sheet metals are digitized using fringe projection systems in different orientations, and afterwards registered into one coordinate frame. The medial axis transformation (MAT) is applied on the point clouds, generating the point clouds of MAT. This data is further processed and medial surface is determined. The thinning defect is detected by evaluating local wall thickness and other defects like wrinkles are determined using the shape recognition on the medial surface. The applied algorithm is simple, fast and robust.

Prioritization in medical school simulation curriculum development using survey tools and desirability function: a pilot experiment.

Ingrassia, Pier Luigi; Barozza, Ludovico Giovanni; Franc, Jeffrey Michael

2018-01-01

In Italy, there is no framework of procedural skills that all medical students should be able to perform autonomously at graduation. The study aims at identifying (1) a set of essential procedural skills and (2) which abilities could be potentially taught with simulation. Desirability score was calculated for each procedure to determine the most effective manner to proceed with simulation curriculum development. A web poll was conducted at the School of Medicine in Novara, looking at the level of expected and self-perceived competency for common medical procedures. Three groups were enrolled: (1) faculty, (2) junior doctors in their first years of practice, and (3) recently graduated medical students. Level of importance of procedural skills for independent practice expressed by teachers, level of mastery self-perceived by learners (students and junior doctors) and suitability of simulation training for the given technical skills were measured. Desirability function was used to set priorities for future learning. The overall mean expected level of competency for the procedural skills was 7.9/9. Mean level of self reported competency was 4.7/9 for junior doctors and 4.4/9 for recently graduated students. The highest priority skills according to the desirability function were urinary catheter placement, nasogastric tube insertion, and incision and drainage of superficial abscesses. This study identifies those technical competencies thought by faculty to be important and assessed the junior doctors and recent graduates level of self-perceived confidence in performing these skills. The study also identifies the perceived utility of teaching these skills by simulation. The study prioritizes those skills that have a gap between expected and observed competency and are also thought to be amenable to teaching by simulation. This allows immediate priorities for simulation curriculum development in the most effective manner. This methodology may be useful to researchers in other centers to prioritize simulation training.

Team Communication Influence on Procedure Performance: Findings From Interprofessional Simulations with Nursing and Medical Students.

PubMed

Reising, Deanna L; Carr, Douglas E; Gindling, Sally; Barnes, Roxie; Garletts, Derrick; Ozdogan, Zulfukar

Interprofessional team performance is believed to be dependent on the development of effective team communication skills. Yet, little evidence exists in undergraduate nursing programs on whether team communication skills affect team performance. A secondary analysis of a larger study on interprofessional student teams in simulations was conducted to determine if there is a relationship between team communication and team procedure performance. The results showed a positive, significant correlation between interprofessional team communication ratings and procedure accuracy in the simulation. Interprofessional team training in communication skills for nursing and medical students improves the procedure accuracy in a simulated setting.

Solid-state and fusion resistance spot welding of TD-NiCr sheet

NASA Technical Reports Server (NTRS)

Moore, T. J.

1973-01-01

By using specially processed TD-NiCr sheet in both 0.4-mm (0.015-in.) and 1.6-mm (0.062-in.) thicknesses and carefully selected welding procedures, solid state resistance spot welds were produced which, after postheating at 1200 C, were indistinguishable from the parent material. Stress-rupture shear tests of single-spot lap joints in 0.4-mm (0.015-in.) thick sheet showed that these welds were as strong as the parent material. Similar results were obtained in tensile-shear tests at room temperature and 1100 C and in fatigue tests. Conventional fusion spot welds in commercial sheet were unsatisfactory because of poor stress-rupture shear properties resulting from metallurgical damage to the parent material.

Fast imaging of live organisms with sculpted light sheets

Light-sheet microscopy is an increasingly popular technique in the life sciences due to its fast 3D imaging capability of fluorescent samples with low photo toxicity compared to confocal methods. In this work we present a new, fast, flexible and simple to implement method to optimize the illumination light-sheet to the requirement at hand. A telescope composed of two electrically tuneable lenses enables us to define thickness and position of the light-sheet independently but accurately within milliseconds, and therefore optimize image quality of the features of interest interactively. We demonstrated the practical benefit of this technique by 1) assembling large field of views from tiled single exposure each with individually optimized illumination settings; 2) sculpting the light-sheet to trace complex sample shapes within single exposures. This technique proved compatible with confocal line scanning detection, further improving image contrast and resolution. Finally, we determined the effect of light-sheet optimization in the context of scattering tissue, devising procedures for balancing image quality, field of view and acquisition speed.

In cell or tissue engineering, it is essential to develop a support for cell-to-cell adhesion, which leads to the generation of cell sheets connected by extracellular matrix. Such supports must be hydrophobic and should result in a detachable cell sheet. A thermoresponsive support that enables the cultured cell sheet to detach using only a change in temperature could be an interesting alternative in regenerative medicine. The aim of this study was to evaluate plates covered with thermoresponsive polymers as supports for the formation of fibroblast sheets and to develop a damage-free procedure for cell sheet transfer with the use of membranes as transfer tools. Human skin fibroblasts were seeded on supports coated with a thermoresponsive polymer: commercial UpCell™ dishes (NUNC™) coated with thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) and dishes coated with thermoresponsive poly(tri(ethylene glycol) monoethyl ether methacrylate) (P(TEGMA-EE)). Confluent fibroblast sheets were effectively cultured and harvested from both commercial PNIPAM-coated dishes and laboratory P(TEGMA-EE)-coated dishes. To transfer a detached cell sheet, two membranes, Immobilon-P(®) and SUPRATHEL(®), were examined. The use of SUPRATHEL for relocating the cell sheets opens a new possibility for the clinical treatment of wounds. This study established the background for implementing thermoresponsive supports for transplanting in vitro cultured fibroblasts.

A study on the effect of varying sequence of lab performance skills on lab performance of high school physics students

NASA Astrophysics Data System (ADS)

Bournia-Petrou, Ethel A.

The main goal of this investigation was to study how student rank in class, student gender and skill sequence affect high school students' performance on the lab skills involved in a laboratory-based inquiry task in physics. The focus of the investigation was the effect of skill sequence as determined by the particular task. The skills considered were: Hypothesis, Procedure, Planning, Data, Graph, Calculations and Conclusion. Three physics lab tasks based on the simple pendulum concept were administered to 282 Regents physics high school students. The reliability of the designed tasks was high. Student performance was evaluated on individual student written responses and a scoring rubric. The tasks had high discrimination power and were of moderate difficulty (65%). It was found that, student performance was weak on Conclusion (42%), Hypothesis (48%), and Procedure (51%), where the numbers in parentheses represent the mean as a percentage of the maximum possible score. Student performance was strong on Calculations (91%), Data (82%), Graph (74%) and Plan (68%). Out of all seven skills, Procedure had the strongest correlation (.73) with the overall task performance. Correlation analysis revealed some strong relationships among the seven skills which were grouped in two distinct clusters: Hypothesis, Procedure and Plan belong to one, and Data, Graph, Calculations, and Conclusion belong to the other. This distinction may indicate different mental processes at play within each skill cluster. The effect of student rank was not statistically significant according to the MANOVA results due to the large variation of rank levels among the participating schools. The effect of gender was significant on the entire test because of performance differences on Calculations and Graph, where male students performed better than female students. Skill sequence had a significant effect on the skills of Procedure, Plan, Data and Conclusion. Students are rather weak in proposing a sensible, detailed procedure for the inquiry task which involves the "novel" concept. However they perform better on Procedure and Plan, if the "novel" task is not preceded by another, which explicitly offers step-by-step procedure instructions. It was concluded that the format of detailed, structured instructions often adopted by many commercial and school-developed lab books and conventional lab practices, fails to prepare students to propose a successful, detailed procedure when faced with a slightly "novel", lab-based inquiry task. Student performance on Data collection was higher in the tasks that involved the more familiar experimental arrangement than in the tasks using the slightly "novel" equipment. Student performance on Conclusion was better in tasks where they had to collect the Data themselves than in tasks, where all relevant Data information was given to them.

Forming Limit Diagram of Titanium and Stainless Steel Alloys to Study the Formability of Hydro-Mechanical Deep Drawing Parts

NASA Astrophysics Data System (ADS)

Shirizly, A.

2005-08-01

The increase demand for stronger, lighter and economic sheet metal products, make the Hydromecanical deep drawing process lately more and more popular. The Hydromecanical process is used in almost all types of sheet metal parts from home appliances and kitchenware to automotive and aviation industries. Therefore, many common materials were tested and characterized by their ability to sustain large strains via the well known Forming Limit Diagram (FLD). The aim of this work is to examine the forming capability if the Hydromecanical process in production of hemisphere parts made of materials commonly used in the aviation and aerospace industries. Experimental procedures were carried out to assess their ductility through FLD and the Forming Limit Carve (FLC).Two type of material sheets were tested herewith for demonstrating the procedure: commercial pure titanium and stainless steel 316L. A numerical simulation of the Hydromecanical process was examined and compared to self made Hydromecanical deep drawing of hemispherical parts.

Robotic assistance became a leading trend in minimally invasive surgery, which is based on the global success of laparoscopic surgery. Manual laparoscopy requires advanced skills and capabilities, which is acquired through tedious learning procedure, while da Vinci type surgical systems offer intuitive control and advanced ergonomics. Nevertheless, in either case, the key issue is to be able to assess objectively the surgeons' skills and capabilities. Robotic devices offer radically new way to collect data during surgical procedures, opening the space for new ways of skill parameterization. This may be revolutionary in MIS training, given the new and objective surgical curriculum and examination methods. The article reviews currently developed skill assessment techniques for robotic surgery and simulators, thoroughly inspecting their validation procedure and utility. In the coming years, these methods will become the mainstream of Western surgical education.

Internists are required to perform a number of procedures that require mastery of technical and non-technical skills, however, formal assessment of these skills is often lacking. The purpose of this study was to develop, implement, and gather validity evidence for a procedural skills objective structured clinical examination (PS-OSCE) for internal medicine (IM) residents to assess their technical and non-technical skills when performing procedures. Thirty-five first to third-year IM residents participated in a 5-station PS-OSCE, which combined partial task models, standardized patients, and allied health professionals. Formal blueprinting was performed and content experts were used to develop the cases and rating instruments. Examiners underwent a frame-of-reference training session to prepare them for their rater role. Scores were compared by levels of training, experience, and to evaluation data from a non-procedural OSCE (IM-OSCE). Reliability was calculated using Generalizability analyses. Reliabilities for the technical and non-technical scores were 0.68 and 0.76, respectively. Third-year residents scored significantly higher than first-year residents on the technical (73.5 vs. 62.2%) and non-technical (83.2 vs. 75.1%) components of the PS-OSCE (p < 0.05). Residents who had performed the procedures more frequently scored higher on three of the five stations (p < 0.05). There was a moderate disattenuated correlation (r = 0.77) between the IM-OSCE and the technical component of the PS-OSCE scores. The PS-OSCE is a feasible method for assessing multiple competencies related to performing procedures and this study provides validity evidence to support its use as an in-training examination.

High stakes medical licensing programs are planning to augment and adapt current examinations to be relevant for a two-decision point model for licensure: entry into supervised practice and entry into unsupervised practice. Therefore, identifying which skills should be assessed at each decision point is critical for informing examination development, and gathering input from residency program directors is important. Using data from previously developed surveys and expert panels, a web-delivered survey was distributed to 3,443 residency program directors. For each of the 28 procedural and 18 advanced communication skills, program directors were asked which clinical skills should be assessed, by whom, when, and how. Descriptive statistics were collected, and Intraclass Correlations (ICC) were conducted to determine consistency across different specialties. Among 347 respondents, program directors reported that all advanced communication and some procedural tasks are important to assess. The following procedures were considered 'important' or 'extremely important' to assess: sterile technique (93.8%), advanced cardiovascular life support (ACLS) (91.1%), basic life support (BLS) (90.0%), interpretation of electrocardiogram (89.4%) and blood gas (88.7%). Program directors reported that most clinical skills should be assessed at the end of the first year of residency (or later) and not before graduation from medical school. A minority were considered important to assess prior to the start of residency training: demonstration of respectfulness (64%), sterile technique (67.2%), BLS (68.9%), ACLS (65.9%) and phlebotomy (63.5%). Results from this study support that assessing procedural skills such as cardiac resuscitation, sterile technique, and phlebotomy would be amenable to assessment at the end of medical school, but most procedural and advanced communications skills would be amenable to assessment at the end of the first year of residency training or later. Gathering data from residency program directors provides support for developing new assessment tools in high-stakes licensing examinations.

Examination of arthroscopic skill requires evaluation tools that are valid and reliable with clear criteria for passing. The Arthroscopic Surgery Skill Evaluation Tool was developed as a video-based assessment of technical skill with criteria for passing established by a panel of experts. The purpose of this study was to test the validity and reliability of the Arthroscopic Surgery Skill Evaluation Tool as a pass-fail examination of arthroscopic skill. Twenty-eight residents and two sports medicine faculty members were recorded performing diagnostic knee arthroscopy on a left and right cadaveric specimen in our arthroscopic skills laboratory. Procedure videos were evaluated with use of the Arthroscopic Surgery Skill Evaluation Tool by two raters blind to subject identity. Subjects were considered to pass the Arthroscopic Surgery Skill Evaluation Tool when they attained scores of ≥ 3 on all eight assessment domains. The raters agreed on a pass-fail rating for fifty-five of sixty videos rated with an interclass correlation coefficient value of 0.83. Ten of thirty participants were assigned passing scores by both raters for both diagnostic arthroscopies performed in the laboratory. Receiver operating characteristic analysis demonstrated that logging more than eighty arthroscopic cases or performing more than thirty-five arthroscopic knee cases was predictive of attaining a passing Arthroscopic Surgery Skill Evaluation Tool score on both procedures performed in the laboratory. The Arthroscopic Surgery Skill Evaluation Tool is valid and reliable as a pass-fail examination of diagnostic arthroscopy of the knee in the simulation laboratory. This study demonstrates that the Arthroscopic Surgery Skill Evaluation Tool may be a useful tool for pass-fail examination of diagnostic arthroscopy of the knee in the simulation laboratory. Further study is necessary to determine whether the Arthroscopic Surgery Skill Evaluation Tool can be used for the assessment of multiple arthroscopic procedures and whether it can be used to evaluate arthroscopic procedures performed in the operating room.

The primary skills that must be possessed in the 21st century curriculum are learning and innovation skills. One of the learning strategies that can train students to innovate and improve creative thinking skills is by applying Science, Technology, Engineering and Mathematics (STEM) in learning. Based on an interview to one of the science teachers that learning that aims to train learning and innovation skills has not been applied to learning in the classroom because there is not enough time, learning materials and assessment instruments used. This study aims to determine the results of the implementation of performance assessment of creative thinking skills on STEM-based learning in junior high school for the material of liquid pressure. This research uses descriptive method. Participants in this study were junior high school students 8th in Kudus area. The research instrument consists of observation sheet, performance assessment and documentation. The result showed that creative thinking skills performance assessment can assess student’s creativity in making products of STEM-based learning for junior high school.

2017-09-01

This study was to investigate the inquiry skills of biology pre-service teachers in one teachers college in Central Java in biotechnology lecture. The method used is a case study of 29 biology preservice teacher. Data were collected using observation sheets, questionnaires, and interview guidelines. Research findings collected through questionnaires show that most students are accustomed to asking questions and formulating biotechnology issues; Skilled in conducting experiments; Skilled in obtaining relevant information from various sources; As well as skilled at processing, analyzing and interpreting data. Based on observation: lectures are not dominated by lecturers, students are able to solve problems encountered and conduct investigations. Based on the interview towards lecturers: students are always actively involved in questioning, investigation, inquiry, problem solving and experimenting in lectures. Why do most students show good inquiry skills? Because students are accustomed to invited inquiry in biology lectures. The impact, the students become more ready to be invited to do more advanced inquiry, such as real-world application inquiry, because the skill of inquiry is essentially trained.

Proposed use of two-part interactive modeling as a means to increase functional skills in children with a variety of disabilities.

Many behavior modification and intervention programs are based on operant procedures developed for animal subjects, but few use modeling procedures in which one student observes interactions between two proficient trainers. We show how such procedures, which successfully trained Grey parrots (Psittacus erithacus) to produce and comprehend elements of human language, can be adapted for use with children with three types of disabilities: (a) autism with limited social and language skills, (b) developmental delay with physical handicaps and lack of language skills, and (c) hyperactivity with impaired cognitive and social skills. Children were evaluated before entering the program and outcomes were recorded to determine improvement levels. No child reached totally normative (physical age-appropriate) levels, but all significantly improved their social and communication skills and use of contextually appropriate behavior. A two-trainer modeling system can be a valuable intervention tool for children whose disabilities involve social and communicative skills.

Direct Observation of Procedural Skills (DOPS) is a way of evaluating procedural skills through observation in the workplace. The purpose of this study was to assess the role of DOPS in teaching and assessment of postgraduate students and to know the effect of repeated DOPS on improvement of the skills and confidence of the students. In both phases, significant difference was observed between the two groups on first DOPS comparison (1st phase: p=0.000; 2nd phase: p=0.002), with simulation group performing better. Comparison of sixth DOPS in the two groups revealed no difference in both phases, but significant difference on first and sixth DOPS comparison in each group (p=0.000). Repeated DOPS results in improved skills and confidence of students in managing real life obstetric emergencies irrespective of the teaching modality. Repeated DOPS results in improved skills and confidence of students in managing real life obstetric emergencies irrespective of the teaching modality.

Innovative production technology in aircraft construction: CIAM Forming 'made by MBB' - A highly productive example

NASA Astrophysics Data System (ADS)

A novel production technology in aircraft construction was developed for manufacturing parts of shapes and dimensions that involve only small quantities for one machine. The process, called computerized integrated and automated manufacturing (CIAM), makes it possible to make ready-to-install sheet-metal parts for all types of aircraft. All of the system's job sequences, which include milling the flat sheet-metal parts in stacks, deburring, heat treatment, and forming under the high-pressure rubber-pad press, are automated. The CIAM production center, called SIAM Forming, fulfills the prerequisites for the cost-effective production of sheet-metal parts made of aluminum alloys, titanium, or steel. The SIAM procedure results in negligible material loss through computerizing both component-contour nesting of the sheet-metal parts and contour milling.

Degradation of learned skills: Effectiveness of practice methods on visual approach and landing skill retention

1972-01-01

Flight control and procedural task skill degradation, and the effectiveness of retraining methods were evaluated for a simulated space vehicle approach and landing under instrument and visual flight conditions. Fifteen experienced pilots were trained and then tested after 4 months either without the benefits of practice or with static rehearsal, dynamic rehearsal or with dynamic warmup practice. Performance on both the flight control and procedure tasks degraded significantly after 4 months. The rehearsal methods effectively countered procedure task skill degradation, while dynamic rehearsal or a combination of static rehearsal and dynamic warmup practice was required for the flight control tasks. The quality of the retraining methods appeared to be primarily dependent on the efficiency of visual cue reinforcement.

Vietnam's nursing competency standards (VNCS) were issued in 2012 as the legal framework on which the continuous nursing training programme are designed and developed. The study aimed to assess the knowledge, skills, and attitudes as well as the confidence of nurses regarding wound care at Viet Duc University Hospital before and after a new educational intervention. A comparative descriptive study was carried out in 2014 at Viet Duc University Hospital. The study reviewed knowledge, skills, attitude and confidence among nurses working in seven clinical departments. The data collection tools included a 48-knowledge-item self-administered questionnaire, a sixteen-item skills set, and attitude-item observation sheet and a thirteen confidence level-item observation sheet, adapted for the field of wound care. Data were loaded into Epidata version 3.1 and analysed with SPSS version 16.0. The mean pre-training knowledge, skill, attitude and confidence scores were (117.78±24.94), (53.61±10.26), (54.39±8.02) and (1.18-3.59), respectively, while the corresponding post-training scores were (148.68±16.54), (62.33±8.40), (60.80±8.75) and (1.50-4.15) p<0.0001. This was the first cohort to undergo the new training programme and has shown promising initial results; however, it also demonstrates that the training content, while leading to positive changes, does in some areas need to be further developed and then disseminated across the hospital to all nurses who provide direct wound care for patients.

[Procedural Motor Skills and Interference in the Academic Life Routine of a Group of Schoolchildren With Signs and Symptoms of ADHD].

2014-03-01

There is a rising prevalence of attention deficit and hyperactivity disorder (ADHD) in educational institutions. Difficulties in academic development manifest as: slow information processing, difficulty in planning and working memory, difficulty staying focused, struggle selecting data or stimuli relevant to the implementation and completion of tasks. If adequate educational measures and specialized intervention are not established, the characteristics may affect instrumental learning. The aim of this study is to identify procedural motor skills that interfere with academic activities in a group of elementary school children, with signs and symptoms of ADHD. Descriptive study including children from 2nd to 4th grade of elementary school in which teachers detected signs and symptoms of ADHD by using questionnaires and observing school behavior. Procedural motor skills were identified and it was evidenced which skills interfered in the execution of academic activities. The population that showed inattention and hyperactivity behaviors manifested behavioral problems, low academic performance, and in turn, greater difficulty in postural skills and skill related with organization of space and objects, which interfered with the activities of daily living academic routine, as expected. The assessment of procedural motor skills allowed to determine specific difficulties in routine activities, and to agree on intervention strategies in the classroom.

2017-01-01

We propose a new ice sheet model validation framework - the Cryospheric Model Comparison Tool (CmCt) - that takes advantage of ice sheet altimetry and gravimetry observations collected over the past several decades and is applied here to modeling of the Greenland ice sheet. We use realistic simulations performed with the Community Ice Sheet Model (CISM) along with two idealized, non-dynamic models to demonstrate the framework and its use. Dynamic simulations with CISM are forced from 1991 to 2013 using combinations of reanalysis-based surface mass balance and observations of outlet glacier flux change. We propose and demonstrate qualitative and quantitative metrics for use in evaluating the different model simulations against the observations. We find that the altimetry observations used here are largely ambiguous in terms of their ability to distinguish one simulation from another. Based on basin- and whole-ice-sheet scale metrics, we find that simulations using both idealized conceptual models and dynamic, numerical models provide an equally reasonable representation of the ice sheet surface (mean elevation differences of <1 m). This is likely due to their short period of record, biases inherent to digital elevation models used for model initial conditions, and biases resulting from firn dynamics, which are not explicitly accounted for in the models or observations. On the other hand, we find that the gravimetry observations used here are able to unambiguously distinguish between simulations of varying complexity, and along with the CmCt, can provide a quantitative score for assessing a particular model and/or simulation. The new framework demonstrates that our proposed metrics can distinguish relatively better from relatively worse simulations and that dynamic ice sheet models, when appropriately initialized and forced with the right boundary conditions, demonstrate predictive skill with respect to observed dynamic changes occurring on Greenland over the past few decades. An extensible design will allow for continued use of the CmCt as future altimetry, gravimetry, and other remotely sensed data become available for use in ice sheet model validation.

2007-04-01

The aims of the study were to quantify levels of dermal and inhalation exposure to antineoplastic drugs in an industrial laundry service in the Netherlands and to test the removal efficiency of the washing procedure for removal of antineoplastic drugs. During four workdays dermal and inhalation exposure to eight frequently used antineoplastic drugs (cyclophosphamide, ifosfamide, methotrexate, 5-fluorouracil, etoposide, cytarabine, gemcitabine and chlorambucil) were measured for all job titles involved in handling unwashed laundry. To test the removal efficiency of the washing procedure, 10 x 10 cm sections were excised before and after the washing procedure. These sections were taken from 15 bed sheets that were collected in hospitals of patients who were treated with one of the selected antineoplastic drugs. During none of the four measurement days, detectable levels of any of the eight antineoplastic drugs (cyclophosphamide, ifosfamide, methotrexate, 5-fluorouracil, etoposide, cytarabine, gemcitabine, or chlorambucil) were found on workers' skin of hands or in any of the air samples. Only four out of the 15 bed sheets from patients that were treated with antineoplastic drugs appeared to be contaminated with detectable levels of antineoplastic drugs before the washing procedure (range 13.0-3,060 ng/100 cm(2)). After the pre-washing and after the complete washing procedure, no detectable levels of any of the eight antineoplastic drugs were found anymore in the selected bed sheets. The implementation of guidelines for working with antineoplastic drugs seems to be successful in reducing exposure to antineoplastic drugs of workers in this laundry facility to an acceptable, non-detectable level and to remove antineoplastic drug contamination from bed linen.

Background Procedural skills training is a critical component of medical education, but is often lacking in standard clinical curricula. We describe a unique immersive procedural skills curriculum for medical students, designed and taught primarily by emergency medicine faculty at The Ohio State University College of Medicine. Objectives The primary educational objective of this program was to formally introduce medical students to clinical procedures thought to be important for success in residency. The immersion strategy (teaching numerous procedures over a 7-day period) was intended to complement the student's education on third-year core clinical clerkships. Program design The course introduced 27 skills over 7 days. Teaching and learning methods included lecture, prereading, videos, task trainers, peer teaching, and procedures practice on cadavers. In year 4 of the program, a peer-team teaching model was adopted. We analyzed program evaluation data over time. Impact Students valued the selection of procedures covered by the course and felt that it helped prepare them for residency (97%). The highest rated activities were the cadaver lab and the advanced cardiac life support (97 and 93% positive endorsement, respectively). Lectures were less well received (73% positive endorsement), but improved over time. The transition to peer-team teaching resulted in improved student ratings of course activities (p<0.001). Conclusion A dedicated procedural skills curriculum successfully supplemented the training medical students received in the clinical setting. Students appreciated hands-on activities and practice. The peer-teaching model improved course evaluations by students, which implies that this was an effective teaching method for adult learners. This course was recently expanded and restructured to place the learning closer to the clinical settings in which skills are applied.

The preschool life skills (PLS) program (Hanley, Heal, Tiger, & Ingvarsson, 2007; Luczynski & Hanley, 2013) involves teaching social skills as a means of decreasing and preventing problem behavior. However, achieving durable outcomes as children transition across educational settings depend on the generalization and long-term maintenance of those skills. The purpose of this study was to evaluate procedures for promoting generalization and long-term maintenance of functional communication and self-control skills for 6 preschool children. When the children's social skills decreased across repeated observations during a generalization assessment, we incorporated modifications to the teaching procedures. However, the effects of the modifications were variable across skills and children. Satisfactory generalization was observed only after the teacher was informed of the target skills and teaching strategies. Maintenance of most social skills was observed 3 months after teaching was discontinued. We discuss the importance of improving child and teacher behavior to promote generalization and maintenance of important social skills. © Society for the Experimental Analysis of Behavior.

Interaction of memory systems during acquisition of tool knowledge and skills in Parkinson's disease.

Roy, Shumita; Park, Norman W; Roy, Eric A; Almeida, Quincy J

2015-01-01

Previous research suggests that different aspects of tool knowledge are mediated by different memory systems. It is believed that tool attributes (e.g., function, color) are represented as declarative memory while skill learning is supported by procedural memory. It has been proposed that other aspects (e.g., skilled tool use) may rely on an interaction of both declarative and procedural memory. However, the specific form of procedural memory underlying skilled tool use and the nature of interaction between declarative and procedural memory systems remain unclear. In the current study, individuals with Parkinson's disease (PD) and healthy controls were trained over 2 sessions, 3 weeks apart, to use a set of novel complex tools. They were also tested on their ability to recall tool attributes as well as their ability to demonstrate grasp and use of the tools to command. Results showed that, compared to controls, participants with PD showed intact motor skill acquisition and tool use to command within sessions, but failed to retain performance across sessions. In contrast, people with PD showed equivalent recall of tool attributes and tool grasping relative to controls, both within and across sessions. Current findings demonstrate that the frontal-striatal network, compromised in PD, mediates long-term retention of motor skills. Intact initial skill learning raises the possibility of compensation from declarative memory for frontal-striatal dysfunction. Lastly, skilled tool use appears to rely on both memory systems which may reflect a cooperative interaction between the two systems. Current findings regarding memory representations of tool knowledge and skill learning may have important implications for delivery of rehabilitation programs for individuals with PD.

Using Gagne's theory to teach procedural skills.

PubMed

Buscombe, Charlotte

2013-10-01

Many key medical procedures are performed every day in clinical practice to yield important diagnostic information and to help determine the disease response to intensive treatments. Training clinicians to perform procedures competently and confidently thus carries considerable weight, helping to assure patient safety, the obtainment of adequate samples and minimising patient discomfort. This article considers how Robert Gagne's instructional design model may be effectively used to design lesson plans and teach procedural skills in small group settings. Gagne's model is based upon the information-processing model of mental events that occur when adults are presented with various stimuli. It highlights nine specific instructional events, which correlate with crucial conditions of learning, and are arranged to maximally enhance the learning process, improve session flow and, ultimately, ensure lesson objectives are comprehensively addressed. This article uses the nine points described by Gagne to outline a comprehensive lesson guide for teaching psychomotor skills, using a bone-marrow aspirate procedure as an example. Each of Gagne's instructional events is considered with specific activities for each, and with the variety of activities delineated to meet diverse learning styles. Gagne's instructional events can produce an effective and comprehensive lesson plan for teaching procedural skills, preparing learners with various preferred learning styles to perform psychomotor skills competently in clinical practice. This lesson plan can be of use for both teachers and students across clinical specialties, encouragingly outlining how Gagne's systematic and widely referenced theory can be creatively and practically used. © 2013 John Wiley & Sons Ltd.

Investigation on bending failure to characterize crashworthiness of 6xxx-series aluminium sheet alloys with bending-tension test procedure

Henn, Philipp; Liewald, Mathias; Sindel, Manfred

2018-05-01

As lightweight design as well as crash performance are crucial to future car body design, exact material characterisation is important to use materials at their full potential and reach maximum efficiency. Within the scope of this paper, the potential of newly established bending-tension test procedure to characterise material crashworthiness is investigated. In this test setup for the determination of material failure, a buckling-bending test is coupled with a subsequent tensile test. If prior bending load is critical, tensile strength and elongation in the subsequent tensile test are dramatically reduced. The new test procedure therefore offers an applicable definition of failure as the incapacity of energy consumption in subsequent phases of the crash represents failure of a component. In addition to that, the correlation of loading condition with actual crash scenarios (buckling and free bending) is improved compared to three- point bending test. The potential of newly established bending-tension test procedure to characterise material crashworthiness is investigated in this experimental studys on two aluminium sheet alloys. Experimental results are validated with existing ductility characterisation from edge compression test.

A two-ply polymer-based flexible tactile sensor sheet using electric capacitance.

PubMed

Guo, Shijie; Shiraoka, Takahisa; Inada, Seisho; Mukai, Toshiharu

2014-01-29

Traditional capacitive tactile sensor sheets usually have a three-layered structure, with a dielectric layer sandwiched by two electrode layers. Each electrode layer has a number of parallel ribbon-like electrodes. The electrodes on the two electrode layers are oriented orthogonally and each crossing point of the two perpendicular electrode arrays makes up a capacitive sensor cell on the sheet. It is well known that compatibility between measuring precision and resolution is difficult, since decreasing the width of the electrodes is required to obtain a high resolution, however, this may lead to reduction of the area of the sensor cells, and as a result, lead to a low Signal/Noise (S/N) ratio. To overcome this problem, a new multilayered structure and related calculation procedure are proposed. This new structure stacks two or more sensor sheets with shifts in position. Both a high precision and a high resolution can be obtained by combining the signals of the stacked sensor sheets. Trial production was made and the effect was confirmed.

This study aimed at investigating pre-service teacher’s critical thinking skills improvement through Higher Order Thinking (HOT) Lab on transformer learning. This research used mix method with the embedded experimental model. Research subjects are 60 students of Physics Education in UIN Sunan Gunung Djati Bandung. The results showed that based on the results of the analysis of practical reports and observation sheet shows students in the experimental group was better in carrying out the practicum and can solve the real problem while the control group was going on the opposite. The critical thinking skills of students applying the HOT Lab were higher than the verification lab. Critical thinking skills could increase due to HOT Lab based problems solving that can develop higher order thinking skills through laboratory activities. Therefore, it was concluded that the application of HOT Lab was more effective than verification lab on improving students’ thinking skills on transformer topic learning. Finally, HOT Lab can be implemented in other subject learning and could be used to improve another higher order thinking skills.

Analysis of fracture in sheet bending and roll forming

Deole, Aditya D.; Barnett, Matthew; Weiss, Matthias

2018-05-01

The bending limit or minimum bending radius of sheet metal is conventionally measured in a wiping (swing arm) or in a vee bend test and reported as the minimum radius of the tool over which the sheet can be bent without fracture. Frequently the material kinks while bending so that the actual inner bend radius of the sheet metal is smaller than the tool radius giving rise to inaccuracy in these methods. It has been shown in the previous studies that conventional bend test methods may under-estimate formability in bending dominated processes such as roll forming. A new test procedure is proposed here to improve understanding and measurement of fracture in bending and roll forming. In this study, conventional wiping test and vee bend test have been performed on martensitic steel to determine the minimum bend radius. In addition, the vee bend test is performed in an Erichsen sheet metal tester equipped with the GOM Aramis system to enable strain measurement on the outer surface during bending. The strain measurement before the onset of fracture is then used to determine the minimum bend radius. To compare this result with a technological process, a vee channel is roll formed and in-situ strain measurement carried out with the Vialux Autogrid system. The strain distribution at fracture in the roll forming process is compared with that predicted by the conventional bending tests and by the improved process. It is shown that for this forming operation and material, the improved procedure gives a more accurate prediction of fracture.

This randomized controlled study compared a novel transparent urinary tract simulator with the traditional opaque urinary tract simulator as an aid for efficiently teaching urological surgical procedures. Senior medical students were tested on their understanding of urological theory before and after lectures concerning urinary system disease. The students received operative training using the transparent urinary tract simulator (experimental group, n = 80) or the J3311 opaque plastic urinary tract simulator (control, n = 80), specifically in catheterization and retrograde double-J stent implantation. The operative training was followed by a skills test and student satisfaction survey. The test scores for theory were similar between the two groups, before and after training. Students in the experimental group performed significantly better than those in the control group on the procedural skills test, and also had significantly better self-directed learning skills, analytical skills, and greater motivation to learn. During the initial step of training, the novel transparent urinary tract simulator significantly improved the efficiency of teaching urological procedural skills compared with the traditional opaque device. © 2015 S.

Light sheet fluorescence microscopy has proven to be a powerful tool to image fixed and chemically cleared samples, providing in depth and high resolution reconstructions of intact mouse organs. We applied light sheet microscopy to image the mouse intestine. We found that large portions of the sample can be readily visualized, assessing the organ status and highlighting the presence of regions with impaired morphology. Yet, three-dimensional (3-D) sectioning of the intestine leads to a large dataset that produces unnecessary storage and processing overload. We developed a routine that extracts the relevant information from a large image stack and provides quantitative analysis of the intestine morphology. This result was achieved by a three step procedure consisting of: (1) virtually unfold the 3-D reconstruction of the intestine; (2) observe it layer-by-layer; and (3) identify distinct villi and statistically analyze multiple samples belonging to different intestinal regions. Even if the procedure has been developed for the murine intestine, most of the underlying concepts have a general applicability.

The transition from basic skills training in a skills lab to procedure training in the operating theater using the traditional master-apprentice model (MAM) lacks uniformity and efficiency. When the supervising surgeon performs parts of a procedure, training opportunities are lost. To minimize this intervention by the supervisor and maximize the actual operating time for the trainee, we created a new training method called INtraoperative Video-Enhanced Surgical Training (INVEST). Ten surgical residents were trained in laparoscopic cholecystectomy either by the MAM or with INVEST. Each trainee performed six cholecystectomies that were objectively evaluated on an Objective Structured Assessment of Technical Skills (OSATS) global rating scale. Absolute and relative improvements during the training curriculum were compared between the groups. A questionnaire evaluated the trainee's opinion on this new training method. Skill improvement on the OSATS global rating scale was significantly greater for the trainees in the INVEST curriculum compared to the MAM, with mean absolute improvement 32.6 versus 14.0 points and mean relative improvement 59.1 versus 34.6% (P=0.02). INVEST significantly enhances technical and procedural skill development during the early learning curve for laparoscopic cholecystectomy. Trainees were positive about the content and the idea of the curriculum.

INTRODUCTION Medical specialties' core curricula should take into account functions to be carried out, positions to be filled and populations to be served. The functions in the professional profile for specialty training of Cuban intensive care and emergency medicine specialists do not include all the activities that they actually perform in professional practice. OBJECTIVE Define the specific functions and procedural skills required of Cuban specialists in intensive care and emergency medicine. METHODS The study was conducted from April 2011 to September 2013. A three-stage methodological strategy was designed using qualitative techniques. By purposive maximum variation sampling, 82 professionals were selected. Documentary analysis and key informant criteria were used in the first stage. Two expert groups were formed in the second stage: one used various group techniques (focus group, oral and written brainstorming) and the second used a three-round Delphi method. In the final stage, a third group of experts was questioned in semistructured in-depth interviews, and a two-round Delphi method was employed to assess priorities. RESULTS Ultimately, 78 specific functions were defined: 47 (60.3%) patient care, 16 (20.5%) managerial, 6 (7.7%) teaching, and 9 (11.5%) research. Thirty-one procedural skills were identified. The specific functions and procedural skills defined relate to the profession's requirements in clinical care of the critically ill, management of patient services, teaching and research at the specialist's different occupational levels. CONCLUSIONS The specific functions and procedural skills required of intensive care and emergency medicine specialists were precisely identified by a scientific method. This product is key to improving the quality of teaching, research, administration and patient care in this specialty in Cuba. The specific functions and procedural skills identified are theoretical, practical, methodological and social contributions to inform future curricular reform and to help intensive care specialists enhance their performance in comprehensive patient care.

In the previous research, CCDSR (Condition, Construction, Development, Simulation, and Reflection) learning model has been developed to improve science process skills for pre-service physics teacher. This research is aimed to analyze the effectiveness of CCDSR learning model towards the improvement skills of creating lesson plan and worksheet of Science Process Skill (SPS) for pre-service physics teacher in academic year 2016/2017. This research used one group pre-test and post-test design on 12 pre-service physics teacher at Physics Education, University of Khairun. Data collection was conducted through test and observation. Creating lesson plan and worksheet SPS skills of pre-service physics teacher measurement were conducted through Science Process Skill Evaluation Sheet (SPSES). The data analysis technique was done by Wilcoxon t-test and n-gain. The CCDSR learning model consists of 5 phases, including (1) Condition, (2) Construction, (3) Development, (4) Simulation, and (5) Reflection. The results showed that there was a significant increase in creating lesson plan and worksheet SPS skills of pre-service physics teacher at α = 5% and n-gain average of moderate category. Thus, the CCDSR learning model is effective for improving skills of creating lesson plan and worksheet SPS for pre-service physics teacher.

Video observation of procedural skills for assessment of trabeculectomy performed by residents.

2016-06-01

The efficacy and sufficiency of a healthcare system is directly related to the knowledge and skills of graduates working in the system. In this regard, many different assessment methods have been proposed to evaluate various skills of the learners. Video Observation of Procedural Skills (VOPS) is one newly-proposed method. In this study we aimed to compare the results of the VOPS method with the more commonly used Direct Observation of Procedural Skills (DOPS). In this prospective study conducted in 2012, all 10 ophthalmology residents of post graduate year 4 were selected for participation. Three months into training in the glaucoma ward, these residents performed trabeculectomy surgery on patients, and their procedural skills were assessed in real time by an expert via the DOPS method. All surgeries were also recorded and later evaluated via the VOPS method by an expert. Bland-Altman plot also was used to compare the two methods and calculating the mean and 95% limit of agreement. Residents have been done a mean of 14.9 ± 3.5 (range 10-20) independent trabeculectomy before the assessments. DOPS grade was positively associated with number of independent trabeculectomy during glaucoma rotation (β=0.227, p = 0.004). The intra-observer reproducibility of VOPS measurements was 0.847 (95% CI: 0.634, 0.961). The mean VOPS grade was significantly lower than the mean DOPS grade (8.4 vs. 8.9, p = 0.02). However, a good correlation was observed between the grades of VOPS and DOPS (r = 0.89, p = 0.001). Bland-Altman analysis demonstrated that all data points fell within the 95% limits of agreement (-1.46, 0.46). The present study showed that VOPS might be considered a feasible, valid, and reliable assessment method for procedural skills of medical students and residents that can be used as an alternative to the DOPS method. However, VOPS might underestimate DOPS in evaluating surgical skills of residents.

Interventions that teach social communication and play skills are crucial for the development of children with autism. The time delay procedure is effective in teaching language acquisition, social use of language, discrete behaviors, and chained activities to individuals with autism and developmental delays. In this study, three boys with autism, attending a non-public school, were taught play activities that combined a play sequence with requesting peer assistance, using a graduated time delay procedure. A multiple-baseline across subjects design demonstrated the success of this procedure to teach multiple-step social play sequences. Results indicated an additional gain of an increase in pretend play by one of the participants. Two also demonstrated a generalization of the skills learned through the time delay procedure.

There is a paucity of articles in the surgical literature demonstrating transfer validity (transfer of training). The purpose of this study was to assess whether skills learned on the ArthroSim virtual-reality arthroscopic knee simulator transferred to greater skill levels in the operating room. Postgraduate year-3 orthopaedic residents were randomized into simulator-trained and control groups at seven academic institutions. The experimental group trained on the simulator, performing a knee diagnostic arthroscopy procedure to a predetermined proficiency level based on the average proficiency of five community-based orthopaedic surgeons performing the same procedure on the simulator. The residents in the control group continued their institution-specific orthopaedic education and training. Both groups then performed a diagnostic knee arthroscopy procedure on a live patient. Video recordings of the arthroscopic surgery were analyzed by five pairs of expert arthroscopic surgeons blinded to the identity of the residents. A proprietary global rating scale and a procedural checklist, which included visualization and probing scales, were used for rating. Forty-eight (89%) of the fifty-four postgraduate year-3 residents from seven academic institutions completed the study. The simulator-trained group averaged eleven hours of training on the simulator to reach proficiency. The simulator-trained group performed significantly better when rated according to our procedural checklist (p = 0.031), including probing skills (p = 0.016) but not visualization skills (p = 0.34), compared with the control group. The procedural checklist weighted probing skills double the weight of visualization skills. The global rating scale failed to reach significance (p = 0.061) because of one extreme outlier. The duration of the procedure was not significant. This lack of a significant difference seemed to be related to the fact that residents in the control group were less thorough, which shortened their time to completion of the arthroscopic procedure. We have demonstrated transfer validity (transfer of training) that residents trained to proficiency on a high-fidelity realistic virtual-reality arthroscopic knee simulator showed a greater skill level in the operating room compared with the control group. We believe that the results of our study will stimulate residency program directors to incorporate surgical simulation into the core curriculum of their residency programs.

Degradation of learned skills. Effectiveness of practice methods on simulated space flight skill retention

NASA Technical Reports Server (NTRS)

Sitterley, T. E.; Berge, W. A.

1972-01-01

Manual flight control and emergency procedure task skill degradation was evaluated after time intervals of from 1 to 6 months. The tasks were associated with a simulated launch through the orbit insertion flight phase of a space vehicle. The results showed that acceptable flight control performance was retained for 2 months, rapidly deteriorating thereafter by a factor of 1.7 to 3.1 depending on the performance measure used. Procedural task performance showed unacceptable degradation after only 1 month, and exceeded an order of magnitude after 4 months. The effectiveness of static rehearsal (checklists and briefings) and dynamic warmup (simulator practice) retraining methods were compared for the two tasks. Static rehearsal effectively countered procedural skill degradation, while some combination of dynamic warmup appeared necessary for flight control skill retention. It was apparent that these differences between methods were not solely a function of task type or retraining method, but were a function of the performance measures used for each task.

Virtual reality (VR) simulators may be useful tools for training and assessing basic and advanced surgical skills and procedures. This study aimed to investigate the construct validity of the LapSimGyn VR simulator, and to determine the learning curves of gynecologists with different levels of experience. For this study, 32 gynecologic trainees and consultants (juniors or seniors) were allocated into three groups: novices (0 advanced laparoscopic procedures), intermediate level (>20 and <60 procedures), and experts (>100 procedures). All performed 10 sets of simulations consisting of three basic skill tasks and an ectopic pregnancy program. The simulations were carried out on 3 days within a maximum period of 2 weeks. Assessment of skills was based on time, economy of movement, and error parameters measured by the simulator. The data showed that expert gynecologists performed significantly and consistently better than intermediate and novice gynecologists. The learning curves differed significantly between the groups, showing that experts start at a higher level and more rapidly reach the plateau of their learning curve than do intermediate and novice groups of surgeons. The LapSimGyn VR simulator package demonstrates construct validity on both the basic skills module and the procedural gynecologic module for ectopic pregnancy. Learning curves can be obtained, but to reach the maximum performance for the more complex tasks, 10 repetitions do not seem sufficient at the given task level and settings. LapSimGyn also seems to be flexible and widely accepted by the users.

More Learners, Finite Resources, and the Changing Landscape of Procedural Training at the Bedside.

There is growing competition for nonoperative, procedural training in teaching hospitals, due to an increased number of individuals seeking to learn procedures from a finite number of appropriate teaching cases. Procedural training is required by students, postgraduate learners, and practicing providers who must maintain their skills. These learner groups are growing in size as the number of medical schools increases and advance practice providers expand their skills to include complex procedures. These various learner needs occur against a background of advancing therapeutic techniques that improve patient care but also act to reduce the overall numbers of procedures available to learners. This article is a brief review of these and other challenges that are arising for program directors, medical school leaders, and hospital administrators who must act to ensure that all of their providers acquire and maintain competency in a wide array of procedural skills. The authors conclude their review with several recommendations to better address procedural training in this new era of learner competition. These include a call for innovative clinical rotations deliberately designed to improve procedural training, access to training opportunities at new clinical sites acquired in health system expansions, targeted faculty development for those who teach procedures, reporting of competition for bedside procedures by trainees, more frequent review of resident procedure and case logs, and the creation of an institutional oversight committee for procedural training.

Natadiwijaya, I. F.; Rahmat, A.; Redjeki, S.; Anggraeni, S.

2018-05-01

Biotechnology content is a more applicative field of science, so learners should be able to have creative thinking skills in applying concepts to problem solving. In this research, Scaffolding learning has been conducted, which is student form of concept development based on constructivism learning paradigm and students build creative thinking skill through the creation of biotechnology product ideas. The research design was R & D method. The subject of this research is a semester V biology education student at Wiralodra University. The instruments used are biotechnology creative thinking tests and program implementation observations. The data of creative thinking test was analyzed using inferential statistic, while the observation sheet used descriptive analysis. The result of this research is the result of students’ creative thinking skill as well as description of the recommended shape and characteristics of the program, with the following results. The scaffolding learning program has a significant influence on students’ creative thinking skill, and the program that trains creative thinking skill is built through two phases, namely phase 1 in concept building where students build their own knowledge, and phase 2 where students build thinking skills creatively through the creation of biotechnology product ideas.

2018-03-01

The essential work of fracture (EWF) method has been explored for indexing the ductile tearing resistance of DP 590 automotive grade dual-phase steel sheet both in longitudinal (L-T) and transverse (T-L) orientations. The simplest possible test and analysis procedures have been adopted. The EWF method is found to be eminently suitable for routine quality control and product development purposes for such materials. Areas for further research for improving the experimental strategy are highlighted. For the investigated steel sheet, the estimated tearing resistance is found to be distinctly higher for the L-T orientation compared to the T-L orientation; the reason thereof merits further investigation.

Cell sheet-based tissue engineering for fabricating 3-dimensional heart tissues.

PubMed

Shimizu, Tatsuya

2014-01-01

In addition to stem cell biology, tissue engineering is an essential research field for regenerative medicine. In contrast to cell injection, bioengineered tissue transplantation minimizes cell loss and has the potential to repair tissue defects. A popular approach is scaffold-based tissue engineering, which utilizes a biodegradable polymer scaffold for seeding cells; however, new techniques of cell sheet-based tissue engineering have been developed. Cell sheets are harvested from temperature-responsive culture dishes by simply lowering the temperature. Monolayer or stacked cell sheets are transplantable directly onto damaged tissues and cell sheet transplantation has already been clinically applied. Cardiac cell sheet stacking produces pulsatile heart tissue; however, lack of vasculature limits the viable tissue thickness to 3 layers. Multistep transplantation of triple-layer cardiac cell sheets cocultured with endothelial cells has been used to form thick vascularized cardiac tissue in vivo. Furthermore, in vitro functional blood vessel formation within 3-dimensional (3D) tissues has been realized by successfully imitating in vivo conditions. Triple-layer cardiac cell sheets containing endothelial cells were layered on vascular beds and the constructs were media-perfused using novel bioreactor systems. Interestingly, cocultured endothelial cells migrate into the vascular beds and form perfusable blood vessels. An in vitro multistep procedure has also enabled the fabrication of thick, vascularized heart tissues. Cell sheet-based tissue engineering has revealed great potential to fabricate 3D cardiac tissues and should contribute to future treatment of severe heart diseases and human tissue model production.

Designing and implementing a skills program Using a clinically integrated, multi-professional approach: Using evaluation to drive curriculum change

PubMed Central

Carr, Sandra E.; Celenza, Antonio; Lake, Fiona

2009-01-01

The essential procedural skills that newly graduated doctors require are rarely defined, do not take into account pre-vocational employer expectations, and differ between Universities. This paper describes how one Faculty used local evaluation data to drive curriculum change and implement a clinically integrated, multi-professional skills program. A curriculum restructure included a review of all undergraduate procedural skills training by academic staff and clinical departments, resulting in a curriculum skills map. Undergraduate training was then linked with postgraduate expectations using the Delphi process to identify the skills requiring structured standardised training. The skills program was designed and implemented without a dedicated simulation center. This paper shows the benefits of an alternate model in which clinical integration of training and multi-professional collaboration encouraged broad ownership of a program and, in turn, impacted the clinical experience obtained.

Simulation for learning and teaching procedural skills: the state of the science.

PubMed

Nestel, Debra; Groom, Jeffrey; Eikeland-Husebø, Sissel; O'Donnell, John M

2011-08-01

Simulation is increasingly used to support learning of procedural skills. Our panel was tasked with summarizing the "best evidence." We addressed the following question: To what extent does simulation support learning and teaching in procedural skills? We conducted a literature search from 2000 to 2010 using Medline, CINAHL, ERIC, and PSYCHINFO databases. Inclusion criteria were established and then data extracted from abstracts according to several categories. Although secondary sources of literature were sourced from key informants and participants at the "Research Consensus Summit: State of the Science," they were not included in the data extraction process but were used to inform discussion. Eighty-one of 1,575 abstracts met inclusion criteria. The uses of simulation for learning and teaching procedural skills were diverse. The most commonly reported simulator type was manikins (n = 17), followed by simulated patients (n = 14), anatomic simulators (eg, part-task) (n = 12), and others. For research design, most abstracts (n = 52) were at Level IV of the National Health and Medical Research Council classification (ie, case series, posttest, or pretest/posttest, with no control group, narrative reviews, and editorials). The most frequent Best Evidence Medical Education ranking was for conclusions probable (n = 37). Using the modified Kirkpatrick scale for impact of educational intervention, the most frequent classification was for modification of knowledge and/or skills (Level 2b) (n = 52). Abstracts assessed skills (n = 47), knowledge (n = 32), and attitude (n = 15) with the majority demonstrating improvements after simulation-based interventions. Studies focused on immediate gains and skills assessments were usually conducted in simulation. The current state of the science finds that simulation usually leads to improved knowledge and skills. Learners and instructors express high levels of satisfaction with the method. While most studies focus on short-term gains attained in the simulation setting, a small number support the transfer of simulation learning to clinical practice. Further study is needed to optimize the alignment of learner, instructor, simulator, setting, and simulation for learning and teaching procedural skills. Instructional design and educational theory, contextualization, transferability, accessibility, and scalability must all be considered in simulation-based education programs. More consistently, robust research designs are required to strengthen the evidence.

Medical school and resident training programmes offer different learning opportunities and outcomes. The aim of the study was to assess medical student and intern experience in common clinical procedures. Interns employed in a metropolitan teaching hospital from 2000 to 2004 completed a survey of experience and confidence in clinical procedures at the beginning and end of their intern year. Attendance at and the contribution to procedural confidence of a voluntary procedural skill-training programme were examined. For the 314 interns, clinical experience before and during internship varied for each procedure and between year cohorts as did training programme attendance (44-84%). Student procedural confidence was predicted by pre-intern experience either on patients or by simulation (beta = 0.17, 95% confidence interval (CI) 0.02-0.21, P = 0.03) and age >30 years on commencing internship (beta = 8.44, 95%CI 3.03-14.06, P = 0.003. Adjusted R(2) = 0.08, P = 0.002). Intern procedural confidence by year's end was predicted by attendance at the training programme (beta = 0.48, 95%CI 0.34-0.62, P < 0.001), intern experience with patient procedures (beta = 0.34, 95%CI 0.21-0.47, P < 0.001) and a clear decision to enter a postgraduate training programme (beta = 0.13, 95%CI 0.04-0.22, P = 0.007, Adjusted R(2) = 0.50, P < 0.001). Interns and students receive variable experience to carry out procedural skills on patients. This makes designing training programmes difficult as training needs vary each year. Both mandatory supervision of key skills and opportunities to supplement limited experience are needed during the intern year to ensure a uniform experience.

Retention of laparoscopic procedural skills acquired on a virtual-reality surgical trainer.

Virtual-reality (VR) simulator training has been shown to improve surgical performance in laparoscopic procedures in the operating room. We have, in a randomised controlled trial, demonstrated transferability to real operations. The validity of the LapSim virtual-reality simulator as an assessment tool has been demonstrated in several reports. However, an unanswered question regarding simulator training is the durability, or retention, of skills acquired during simulator training. The aim of the present study is to assess the retention of skills acquired using the LapSim VR simulator, 6 and 18 months after an initial training course. The investigation was designed as a 6- and 18-month follow-up on a cohort of participants who earlier participated in a skills training programme on the LapSim VR. The follow-up cohort consisted of trainees and senior consultants allocated to two groups: (1) novices (experience < 5 procedures, n = 9) and (2) experts (experience > 200 procedures during the past 3 years, n = 10). Each participant performed ten sessions. Assessment of skills was based on time, economy of movement and the error parameter "bleeding". The novice group were re-tested after 6 and 18 months, whereas the expert group were only retested once, after 6 months. None of the novices performed laparoscopic surgery in the follow-up period. The experts continued their daily work with laparoscopic surgery. Novices showed retention of skills after 6 months. After 18 months, novices' laparoscopic skills had returned to the pre-training level. This indicates that laparoscopic skills seemed to deteriorate in the period between 6 and 18 months without training. Experts showed consistent performance over time. This information can be included when planning training curricula in minimal invasive surgery.

The purpose of this study was to create a technical skills assessment toolbox for 35 basic and advanced skills/procedures that comprise the American College of Surgeons (ACS)/Association of Program Directors in Surgery (APDS) surgical skills curriculum and to provide a critical appraisal of the included tools, using contemporary framework of validity. Competency-based training has become the predominant model in surgical education and assessment of performance is an essential component. Assessment methods must produce valid results to accurately determine the level of competency. A search was performed, using PubMed and Google Scholar, to identify tools that have been developed for assessment of the targeted technical skills. A total of 23 assessment tools for the 35 ACS/APDS skills modules were identified. Some tools, such as Operative Performance Rating System (OSATS) and Objective Structured Assessment of Technical Skill (OPRS), have been tested for more than 1 procedure. Therefore, 30 modules had at least 1 assessment tool, with some common surgical procedures being addressed by several tools. Five modules had none. Only 3 studies used Messick's framework to design their validity studies. The remaining studies used an outdated framework on the basis of "types of validity." When analyzed using the contemporary framework, few of these studies demonstrated validity for content, internal structure, and relationship to other variables. This study provides an assessment toolbox for common surgical skills/procedures. Our review shows that few authors have used the contemporary unitary concept of validity for development of their assessment tools. As we progress toward competency-based training, future studies should provide evidence for various sources of validity using the contemporary framework.

The challenges of maintaining comprehensive banks of valid checklists make context-specific checklists for assessment of clinical procedural skills problematic. This paper reports the development of a tool which supports generic holistic assessment of clinical procedural skills. We carried out a literature review, focus groups and non-participant observation of assessments with interview of participants, participant evaluation of a pilot objective structured clinical examination (OSCE), a national modified Delphi study with prior definitions of consensus and an OSCE. Participants were volunteers from a large acute teaching trust, a teaching primary care trust and a national sample of National Health Service staff. Results In total, 86 students, trainees and staff took part in the focus groups, observation of assessments and pilot OSCE, 252 in the Delphi study and 46 candidates and 50 assessors in the final OSCE. We developed a prototype tool with 5 broad categories amongst which were distributed 38 component competencies. There was > 70% agreement (our prior definition of consensus) at the first round of the Delphi study for inclusion of all categories and themes and no consensus for inclusion of additional categories or themes. Generalisability was 0.76. An OSCE based on the instrument has a predicted reliability of 0.79 with 12 stations and 1 assessor per station or 10 stations and 2 assessors per station. This clinical procedural skills assessment tool enables reliable assessment and has content and face validity for the assessment of clinical procedural skills. We have designated it the Leicester Clinical Procedure Assessment Tool (LCAT).

2016-01-01

A competent review process is crucial to ensure the quality of multiple-choice (MC) questions. However, the acquisition of reviewing skills should not cause any unnecessary additional burden for a medical staff that is already facing heavy workloads. 100 MC questions, for which an expert review existed, were presented to 12 novices. In advance, six participants received a specific information sheet covering critical information for high-calibre review; the other six participants attended a 2.5-hour workshop covering the same information. The review results of both groups were analysed with a licensed version of the IBM software SPSS 19.0 (SPSS Inc., Chicago, IL). The results of the workshop group were distinctly closer to the experts' results (gold standard) than those of the information sheet group. For the quantitatively important category of medium quality MC questions, the results of the workshop group did not significantly differ from the experts' results. In the information sheet group the results were significantly poorer than the experts', regardless of the quality of the questions. Distributing specific information sheets to MC question reviewers is not sufficient for ensuring the quality of the review so that - regardless of the increased effort involved - a recommendation to conduct specific workshops must be made.

Most studies of simulator-based surgical skills training have focused on the acquisition of psychomotor skills, but surgical procedures are complex tasks requiring both psychomotor and cognitive skills. As skills training is modelled on expert performance consisting partly of unconscious automatic processes that experts are not always able to explicate, simulator developers should collaborate with educational experts and physicians in developing efficient and effective training programmes. This article presents an approach to designing simulator-based skill training comprising cognitive task analysis integrated with instructional design according to the four-component/instructional design model. This theory-driven approach is illustrated by a description of how it was used in the development of simulator-based training for the nephrostomy procedure.

2002-01-01

Children with hydrocephalus have poor math skills. We investigated the nature of their arithmetic computation errors by comparing written subtraction errors in good readers with hydrocephalus, typically developing good readers of the same age, and younger children matched for math level to the children with hydrocephalus. Children with hydrocephalus made more procedural errors (although not more fact retrieval or visual-spatial errors) than age-matched controls; they made the same number of procedural errors as younger, math-level matched children. We also investigated a broad range of math abilities, and found that children with hydrocephalus performed more poorly than age-matched controls on tests of geometry and applied math skills such as estimation and problem solving. Computation deficits in children with hydrocephalus reflect delayed development of procedural knowledge. Problems in specific math domains such as geometry and applied math, were associated with deficits in constituent cognitive skills such as visual spatial competence, memory, and general knowledge.

We propose a new ice sheet model validation framework - the Cryospheric Model Comparison Tool (CmCt) - that takes advantage of ice sheet altimetry and gravimetry observations collected over the past several decades and is applied here to modeling of the Greenland ice sheet. We use realistic simulations performed with the Community Ice Sheet Model (CISM) along with two idealized, non-dynamic models to demonstrate the framework and its use. Dynamic simulations with CISM are forced from 1991 to 2013, using combinations of reanalysis-based surface mass balance and observations of outlet glacier flux change. We propose and demonstrate qualitative and quantitative metrics for use in evaluating the different model simulations against the observations. We find that the altimetry observations used here are largely ambiguous in terms of their ability to distinguish one simulation from another. Based on basin-scale and whole-ice-sheet-scale metrics, we find that simulations using both idealized conceptual models and dynamic, numerical models provide an equally reasonable representation of the ice sheet surface (mean elevation differences of < 1 m). This is likely due to their short period of record, biases inherent to digital elevation models used for model initial conditions, and biases resulting from firn dynamics, which are not explicitly accounted for in the models or observations. On the other hand, we find that the gravimetry observations used here are able to unambiguously distinguish between simulations of varying complexity, and along with the CmCt, can provide a quantitative score for assessing a particular model and/or simulation. The new framework demonstrates that our proposed metrics can distinguish relatively better from relatively worse simulations and that dynamic ice sheet models, when appropriately initialized and forced with the right boundary conditions, demonstrate a predictive skill with respect to observed dynamic changes that have occurred on Greenland over the past few decades. An extensible design will allow for continued use of the CmCt as future altimetry, gravimetry, and other remotely sensed data become available for use in ice sheet model validation.

An ice sheet model validation framework for the Greenland ice sheet

We propose a new ice sheet model validation framework the Cryospheric Model Comparison Tool (CMCT) that takes advantage of ice sheet altimetry and gravimetry observations collected over the past several decades and is applied here to modeling of the Greenland ice sheet. We use realistic simulations performed with the Community Ice Sheet Model (CISM) along with two idealized, non-dynamic models to demonstrate the framework and its use. Dynamic simulations with CISM are forced from 1991 to 2013 using combinations of reanalysis-based surface mass balance and observations of outlet glacier flux change. We propose and demonstrate qualitative and quanti- tative metricsmore » for use in evaluating the different model simulations against the observations. We find 10 that the altimetry observations used here are largely ambiguous in terms of their ability to distinguish one simulation from another. Based on basin- and whole-ice-sheet scale metrics, the model initial condition as well as output from idealized and dynamic models all provide an equally reasonable representation of the ice sheet surface (mean elevation differences of <1 m). This is likely due to their short period of record, biases inherent to digital elevation models used for model initial conditions, and biases resulting from firn dynamics, which are not explicitly accounted for in the models or observations. On the other hand, we find that the gravimetry observations used here are able to unambiguously distinguish between simulations of varying complexity, and along with the CMCT, can provide a quantitative score for assessing a particular model and/or simulation. The new framework demonstrates that our proposed metrics can distinguish relatively better from relatively worse simulations and that dynamic ice sheet models, when appropriately initialized and forced with the right boundary conditions, demonstrate predictive skill with respect to observed dynamic changes occurring on Greenland over the past few decades.

Background Procedural memory allows acquisition, consolidation and use of motor skills and cognitive routines. Automation of procedures is achieved through repeated practice. In children, improvement in procedural skills is a consequence of natural neurobiological development and experience. Methods The aim of the present research was to make a preliminary evaluation and description of repetition-based improvement of procedures in typically developing children (TDC). Ninety TDC children aged 6–12 years were asked to perform two procedural learning tasks. In an assembly learning task, which requires predominantly motor skills, we measured the number of assembled pieces in 60 seconds. In a mirror drawing learning task, which requires more cognitive functions, we measured time spent and efficiency. Participants were tested four times for each task: three trials were consecutive and the fourth trial was performed after a 10-minute nonverbal interference task. The influence of repeated practice on performance was evaluated by means of the analysis of variance with repeated measures and the paired-sample test. Correlation coefficients and simple linear regression test were used to examine the relationship between age and performance. Results TDC achieved higher scores in both tasks through repetition. Older children fitted more pieces than younger ones in assembling learning and they were faster and more efficient at the mirror drawing learning task. Conclusions These findings indicate that three consecutive trials at a procedural task increased speed and efficiency, and that age affected basal performance in motor-cognitive procedures.

Development of virtual environments for training skills and reducing errors in laparoscopic surgery

NASA Astrophysics Data System (ADS)

Tendick, Frank; Downes, Michael S.; Cavusoglu, Murat C.; Gantert, Walter A.; Way, Lawrence W.

1998-06-01

In every surgical procedure there are key steps and skills that, if performed incorrectly, can lead to complications. In conjunction with efforts, based on task and error analysis, in the Videoscopic Training Center at UCSF to identify these key elements in laparoscopic surgical procedures, the authors are developing virtual environments and modeling methods to train the elements. Laparoscopic surgery is particularly demanding of the surgeon's spatial skills, requiring the ability to create 3D mental models and plans while viewing a 2D image. For example, operating a laparoscope with the objective lens angled from the scope axis is a skill that some surgeons have difficulty mastering, even after using the instrument in many procedures. Virtual environments are a promising medium for teaching spatial skills. A kinematically accurate model of an angled laparoscope in an environment of simple targets is being tested in courses for novice and experienced surgeons. Errors in surgery are often due to a misinterpretation of local anatomy compounded with inadequate procedural knowledge. Methods to avoid bile duct injuries in cholecystectomy are being integrated into a deformable environment consisting of the liver, gallbladder, and biliary tree. Novel deformable tissue modeling algorithms based on finite element methods will be used to improve the response of the anatomical models.

Laser based spot weld characterization

Jonietz, Florian; Myrach, Philipp; Rethmeier, Michael; Suwala, Hubert; Ziegler, Mathias

2016-02-01

Spot welding is one of the most important joining technologies, especially in the automotive industry. Hitherto, the quality of spot welded joints is tested mainly by random destructive tests. A nondestructive testing technique offers the benefit of cost reduction of the testing procedure and optimization of the fabrication process, because every joint could be examined. This would lead to a reduced number of spot welded joints, as redundancies could be avoided. In the procedure described here, the spot welded joint between two zinc-coated steel sheets (HX340LAD+Z100MB or HC340LA+ZE 50/50) is heated optically on one side. Laser radiation and flash light are used as heat sources. The melted zone, the so called "weld nugget" provides the mechanical stability of the connection, but also constitutes a thermal bridge between the sheets. Due to the better thermal contact, the spot welded joint reveals a thermal behavior different from the surrounding material, where the heat transfer between the two sheets is much lower. The difference in the transient thermal behavior is measured with time resolved thermography. Hence, the size of the thermal contact between the two sheets is determined, which is directly correlated to the size of the weld nugget, indicating the quality of the spot weld. The method performs well in transmission with laser radiation and flash light. With laser radiation, it works even in reflection geometry, thus offering the possibility of testing with just one-sided accessibility. By using heating with collimated laser radiation, not only contact-free, but also remote testing is feasible. A further convenience compared to similar thermographic approaches is the applicability on bare steel sheets without any optical coating for emissivity correction. For this purpose, a proper way of emissivity correction was established.

Procedural training and assessment of competency utilizing simulation.

PubMed

Sawyer, Taylor; Gray, Megan M

2016-11-01

This review examines the current environment of neonatal procedural learning, describes an updated model of skills training, defines the role of simulation in assessing competency, and discusses potential future directions for simulation-based competency assessment. In order to maximize impact, simulation-based procedural training programs should follow a standardized and evidence-based approach to designing and evaluating educational activities. Simulation can be used to facilitate the evaluation of competency, but must incorporate validated assessment tools to ensure quality and consistency. True competency evaluation cannot be accomplished with simulation alone: competency assessment must also include evaluations of procedural skill during actual clinical care. Future work in this area is needed to measure and track clinically meaningful patient outcomes resulting from simulation-based training, examine the use of simulation to assist physicians undergoing re-entry to practice, and to examine the use of procedural skills simulation as part of a maintenance of competency and life-long learning.

Nontechnical skill training and the use of scenarios in modern surgical education.

Brunckhorst, Oliver; Khan, Muhammad S; Dasgupta, Prokar; Ahmed, Kamran

2017-07-01

Nontechnical skills are being increasingly recognized as a core reason of surgical errors. Combined with the changing nature of surgical training, there has therefore been an increase in nontechnical skill research in the literature. This review therefore aims to: define nontechnical skillsets, assess current training methods, explore assessment modalities and suggest future research aims. The literature demonstrates an increasing understanding of the components of nontechnical skills within surgery. This has led to a greater availability of validated training methods for its training, including the use of didactic teaching, e-learning and simulation-based scenarios. In addition, there are now various extensively validated assessment tools for nontechnical skills including NOTSS, the Oxford NOTECHS and OTAS. Finally, there is now more focus on the development of tools which target individual nontechnical skill components and an attempt to understand which of these play a greater role in specific procedures such as laparoscopic or robotic surgery. Current evidence demonstrates various training methods and tools for the training of nontechnical skills. Future research is likely to focus increasingly on individual nontechnical skill components and procedure-specific skills.

Applications of Computer Simulation Methods in Plastic Forming Technologies for Magnesium Alloys

NASA Astrophysics Data System (ADS)

Zhang, S. H.; Zheng, W. T.; Shang, Y. L.; Wu, X.; Palumbo, G.; Tricarico, L.

2007-05-01

Applications of computer simulation methods in plastic forming of magnesium alloy parts are discussed. As magnesium alloys possess very poor plastic formability at room temperature, various methods have been tried to improve the formability, for example, suitable rolling process and annealing procedures should be found to produce qualified magnesium alloy sheets, which have the reduced anisotropy and improved formability. The blank can be heated to a warm temperature or a hot temperature; a suitable temperature field is designed, tools should be heated or the punch should be cooled; suitable deformation speed should be found to ensure suitable strain rate range. Damage theory considering non-isothermal forming is established. Various modeling methods have been tried to consider above situations. The following situations for modeling the forming process of magnesium alloy sheets and tubes are dealt with: (1) modeling for predicting wrinkling and anisotropy of sheet warm forming; (2) damage theory used for predicting ruptures in sheet warm forming; (3) modeling for optimizing of blank shape and dimensions for sheet warm forming; (4) modeling in non-steady-state creep in hot metal gas forming of AZ31 tubes.

Skill transfer represents an important issue in surgical education, and is not well understood. The aim of this randomized study is to assess the transferability of surgical skills between two laparoscopic abdominal procedures using the virtual reality simulator in surgical novices. From September 2016 to July 2017, 44 surgical novices were randomized into two groups and underwent a proficiency-based basic training consisting of five selected simulated laparoscopic tasks. In group 1, participants performed an appendectomy training on the virtual reality simulator until they reached a defined proficiency. They moved on to the tutorial procedural tasks of laparoscopic cholecystectomy. Participants in group 2 started with the tutorial procedural tasks of laparoscopic cholecystectomy directly. Finishing the training, participants of both groups were required to perform a complete cholecystectomy on the simulator. Time, safety and economy parameters were analysed. Significant differences in the demographic characteristics and previous computer games experience between the two groups were not noted. Both groups took similar time to complete the proficiency-based basic training. Participants in group 1 needed significantly less movements (388.6 ± 98.6 vs. 446.4 ± 81.6; P < 0.05) as well as shorter path length (810.2 ± 159.5 vs. 945.5 ± 187.8 cm; P < 0.05) to complete the cholecystectomy compared to group 2. Time and safety parameters did not differ significantly between both groups. The data demonstrate a positive transfer of motor skills between laparoscopic appendectomy and cholecystectomy on the virtual reality simulator; however, the transfer of cognitive skills is limited. Separate training curricula seem to be necessary for each procedure for trainees to practise task-specific cognitive skills effectively. Mentoring could help trainees to get a deeper understanding of the procedures, thereby increasing the chance for the transfer of acquired skills.

Combining cognitive skills teaching related to the techniques leads to better understanding in a skill training course; but still there a substantial disagreement in curriculum on such combinations. This study aims to help guide the designers in making the outline of instructional plan for a Clinical Skills Module (CSM) for the undergraduates. Objectives were to assess performance of students on a clinical skill after training by two different models of (hands-on only or with cognitive skills) instructions and explore their perception on the employment of educational strategies through Focus Group Discussions (FGD) through a Sequential mixed method study design: (1) Quantitative (Pre- and post-assessments and comparing their results (2) Qualitative (Exploration of perspectives through constructivist approach using qualitative phenomenological design) The study was conducted during the month of September, 2015 at Rabigh Medical College, King Abdul Aziz University, Jeddah. Students entering fourth year were randomized to two groups to participate in pre-post OSCE using global rating scale and their scores were compared. The examiners were kept blinded to the randomization of students undergoing two separate training methods. The test group (group A) was trained for both procedural as well as cognitive skills whereas the control group (Group-B) was trained only with hands-on practice. Later their perception about the addition of cognitive skills to improve of procedural skills was explored through focus group discussions. The recorded audio tapes of FGDs were transcribed and analysed thematically. Triangulation of themes and trends was achieved by relating the content analysis to the relevant frequency of quotes. Auditing of the data verification was done by all the authors separately.. A total of 42 students completed both pre- and post-tests. As a result, student performance in OSCE significantly increased from pre- to post-test (p<0.001) in both the groups; on the other hand no statistically significant difference was found in the pre- and posttest scores between groups A and B (p=0.108). Five themes (1) advantages, (2) disadvantages of combining theory with practice, (3) time balance in teaching a skill, (4) training on skills, (5) skillsassessment, were found prevalent on thematic analysis of the FGDs. Students' ability to grasp the procedural skills was not significantly different when they acquire the cognitive skills in addition to the practical sessions. Students were more convinced to adopt combination of the two in the learning of procedural skills.

Influence of compost covers on the efficiency of biowaste composting process.

Marešová, Karolina; Kollárová, Mária

2010-12-01

The temperature of matured compost is an indicator of feedstock quality and also a good feedback informing about the suitability of an applied technological procedure. Two independent experiments using the technology of windrow composting at open area were conducted with the final goal to evaluate the effect of compost pile covering (in comparison with uncovered piles) on the course of composting process - behaviour of temperature over time and oxygen content. Two types of sheets were used - Top Tex permeable sheet and impermeable polyethylene sheet. The experiment I (summer months) aimed at comparison of efficiency between the Top Tex sheet cover and the uncovered compost piles, while experiment II (autumn months) compared treatments using the Top Tex sheet and polyethylene sheet by contrast. Within the experiment I the composts consisted of cattle slurry and fresh grass matter at a ratio of 1:1, in case of experiment II consisted of pig/cattle manure, fresh grass matter and chipped material at a ratio of about 1:2:1. The obtained data showed no significant differences among the cover treatments according to ANOVA. The only exception was oxygen content in pile 4 (experiment II) under Top Tex sheet, where a markedly higher oxygen content than under polyethylene sheet was measured during the whole composting period. It was the only case where statistical analysis proved a significant difference; the p-value was 0.0002. Copyright © 2010. Published by Elsevier Ltd.

A Pilot Study of Simple Interventions to Improve Informed Consent in Clinical Research: Feasibility, Approach, and Results

Background Informed consent is intended to ensure that individuals understand the purpose, risks, and benefits of research studies, and then can decide, voluntarily, whether to enroll. However, research suggests that consent procedures do not always lead to adequate participant understanding and may be longer and more complex than necessary. Studies also suggest some consent interventions, including enhanced consent forms and extended discussions with patients, increase understanding, yet methodologic challenges have been raised in studying consent in actual trial settings. This study aimed to examine the feasibility of testing two consent interventions in actual studies and also to measure effectiveness of interventions in improving understanding of trials. Methods Participants enrolling in any of eight ongoing clinical trials (“collaborating studies”) were, for the purposes of this study, sequentially assigned to one of three study arms involving different informed consent procedures (one control and two intervention). Control participants received standard consent form and processes. Participants in the 1st intervention arm received a bulleted fact-sheet providing simple summaries of all study components in addition to the standard consent form. Participants in the 2nd intervention arm received the bulleted fact-sheet and standard consent materials and then also engaged with a member of the collaborating study staff in a feedback Q&A session. Following consent procedures, we administered closed and open ended questions to assess patient understanding and we assessed literacy level. Descriptive statistics, Wilcoxon-Mann-Whitney and Kruskal-Wallis tests were generated to assess correlations; regression analysis determined predictors of patient understanding. Results 144 participants enrolled. Using regression analysis participants receiving the 2nd intervention, which included a standard consent form, bulleted fact sheet and structured question and answer session with a study staff member, had open-ended question scores that were 7.6 percentage points higher (p=.02) than participants who received the control arm (standard consent only), although unadjusted comparisons did not reach statistical significance. Eleven clinical trial investigators agreed to participate and 8 trials provided sufficient data to be included, thereby demonstrating feasibility of consent research in actual settings. Conclusions Our study supports the hypothesis that patients receiving both bulleted fact sheets and a question and answer session have higher understanding compared to patients receiving standard consent form and procedures alone. Fact sheets and short structured dialog are quick to administer and easy to replicate across studies and should be tested in larger samples for effectiveness. PMID:25475879

Effects of dividing attention on memory for declarative and procedural aspects of tool use.

PubMed

Roy, Shumita; Park, Norman W

2016-07-01

Tool-related knowledge and skills are supported by a complex set of memory processes that are not well understood. Some aspects of tools are mediated by either declarative or procedural memory, while other aspects may rely on an interaction of both systems. Although motor skill learning is believed to be primarily supported by procedural memory, there is debate in the current literature regarding the role of declarative memory. Growing evidence suggests that declarative memory may be involved during early stages of motor skill learning, although findings have been mixed. In the current experiment, healthy, younger adults were trained to use a set of novel complex tools and were tested on their memory for various aspects of the tools. Declarative memory encoding was interrupted by dividing attention during training. Findings showed that dividing attention during training was detrimental for subsequent memory for tool attributes as well as accurate demonstration of tool use and tool grasping. However, dividing attention did not interfere with motor skill learning, suggesting that declarative memory is not essential for skill learning associated with tools.

In medical practice, obtaining information regarding patients' undisclosed "feelings of anxiety" or "depressive feelings" is important. The purpose of this study was to determine which interview skills are best suited for eliciting verbal indications of undisclosed feelings, for example anxiety or depressive feelings in patients. Our group videotaped 159 medical interviews at an outpatient department of the Department of Family Medicine, Mie University Hospital (Mie, Japan). Physicians' medical interview skills were evaluated using a Medical Interview Evaluation System and Emotional Information Check Sheet for assessing indications of "feelings of anxiety" or "depressive feelings". We analyzed the relationship between the interview skills and patients' consequent emotional disclosure using generalized linear model (GLIM). The usage of interview skills such as "open-ended questions" "asking the patient's ideas about the meaning of illness" "reflection" and "legitimization" were positively associated with the number of anxiety disclosure, whereas "close-ended questions" and "focused question" were negatively associated. On the other hand, only "respect" was positively associated with the number of depressive disclosures, whereas "surveying question" was negatively associated. The results revealed that there are several interview skills that are effective in eliciting verbal indication of undisclosed "feelings of anxiety" or "depressive feelings".

2016-01-01

The aim of this study was to explore the differences in procedural learning abilities between children with DCD and typically developing children by investigating the steps that lead to skill automatization (i.e., the stages of fast learning, consolidation, and slow learning). Transfer of the skill to a new situation was also assessed. We tested 34 children aged 6-12 years with and without DCD on a perceptuomotor adaptation task, a form of procedural learning that is thought to involve the cerebellum and the basal ganglia (regions whose impairment has been associated with DCD) but also other brain areas including frontal regions. The results showed similar rates of learning, consolidation, and transfer in DCD and control children. However, the DCD children's performance remained slower than that of controls throughout the procedural task and they reached a lower asymptotic performance level; the difficulties observed at the outset did not diminish with practice.

To report the preferences of Fellows of the Australasian College for Emergency Medicine for topics they would desire for their continuing professional development (CPD). A mailed survey of Fellows of the Australasian College for Emergency Medicine asked for Likert type responses on the desirability of CPD on 15 procedural skills, 13 management skills, 11 clinical emergency topics, 9 topics related to teaching, 7 related to diagnostics and 5 evidence based practice topics. CPD in procedural skills of advanced and surgical airways, ED ultrasound, ventilation, skills, plastic procedures and regional anaesthesia were nominated as desirable by 85% of emergency physicians (EP). More than 90% desired CPD in ophthalmological, otorhinolaryngeal, neonatal and paediatric emergencies. Of diagnostic skills, more than 80% considered CPD on computerized tomography, electrocardiography and plain X-ray interpretation as desirable, well as CPD about teaching in general, simulation and preparing candidates for fellowship exams. Of the 12 management skills, 11 were seen as desirable topics by more than 70%, with counter disaster planning, giving feedback and dealing with complaints the most popular. All evidence based practice related skills, including interpreting statistics and undertaking literature searches were seen as desirable topics by more than 80% of EP. This information may assist in the planning of future educational interventions for emergency physicians. EP seek CPD on management, educational and other non clinical skills, as well as topics relating directly to patient care.

We evaluated integration of an introductory ultrasound curriculum into our existing mandatory procedural skills program for preclinical medical students. Phantoms consisting of olives, pimento olives, and grapes embedded in opaque gelatin were developed. Four classes encouraged progressive refinement of phantom-scanning and object identification skills. Students improved their ability to identify hidden objects, although each object type achieved a statistically significant improvement in correct identification at different time points. The total phantom cost per student was $0.76. Our results suggest that short repeated experiences scanning simple, low-cost ultrasound phantoms confer basic ultrasound skills. © 2016 by the American Institute of Ultrasound in Medicine.

Lumbar puncture simulation in pediatric residency training: improving procedural competence and decreasing anxiety.

Pediatric residents must become proficient with performing a lumbar puncture (LP) during training. Residents have traditionally acquired LP skills by observing the procedure performed by a more senior resident or staff physician and then attempting the procedure themselves. This process can result in variable procedural skill acquisition and trainee discomfort. This study assessed changes in resident procedural skill and self-reported anxiety when residents were provided with an opportunity to participate in an interactive training session and practice LPs using a simulator. All pediatric residents at our institution were invited to participate. Residents were asked to report their post-graduate year (PGY), prior LP attempts and self-reported anxiety scores as measured by the standardized State-Trait Anxiety Inventory - State Anxiety Scale (STAI-S) prior to completing an observed pre-test using an infant-sized LP simulator. Staff physicians observed and scored each resident's procedural skill using a previously published 21-point scoring system. Residents then participated in an interactive lecture on LP technique and were given an opportunity for staff-supervised, small group simulator-based practice within 1 month of the pre-test. Repeat post-test was performed within 4 months. Of the pediatric residents who completed the pre-test (N = 20), 16/20 (80 %) completed both the training session and post-test. Their PGY training level was: PGY1 (38 %), PGY2 (25 %), PGY3 (25 %) or PGY4 (12 %). Procedural skill improved in 15/16 residents (paired t-test; p < 0.001), driven by a significant improvement in skill for residents in PGY1 (P = 0.015) and PGY2 (p = 0.003) but not PGY3 or PGY4. Overall anxiety scores were higher at baseline than at post testing (mean ± SD; 44.8 ± 12.1 vs 39.7 ± 9.4; NS) however only PGY1 residents experienced a significant reduction in anxiety (paired t-test, p = 0.04). LP simulation training combined with an interactive training session may be a useful tool for improving procedural competence and decreasing anxiety levels, particularly among those at an earlier stage of residency training.

2015-06-15

Objective assessment of surgical skills is resource intensive and requires valuable time of expert surgeons. The goal of this study was to assess the ability of a large group of laypersons using a crowd-sourcing tool to grade a surgical procedure (cricothyrotomy) performed on a simulator. The grading included an assessment of the entire procedure by completing an objective assessment of technical skills survey. Two groups of graders were recruited as follows: (1) Amazon Mechanical Turk users and (2) three expert surgeons from University of Washington Department of Otolaryngology. Graders were presented with a video of participants performing the procedure on the simulator and were asked to grade the video using the objective assessment of technical skills questions. Mechanical Turk users were paid $0.50 for each completed survey. It took 10 h to obtain all responses from 30 Mechanical Turk users for 26 training participants (26 videos/tasks), whereas it took 60 d for three expert surgeons to complete the same 26 tasks. The assessment of surgical performance by a group (n = 30) of laypersons matched the assessment by a group (n = 3) of expert surgeons with a good level of agreement determined by Cronbach alpha coefficient = 0.83. We found crowd sourcing was an efficient, accurate, and inexpensive method for skills assessment with a good level of agreement to experts' grading. Copyright © 2015 Elsevier Inc.

Specificity and transfer effects in time production skill: examining the role of attention.

PubMed

Wohldmann, Erica L; Healy, Alice F; Bourne, Lyle E

2012-05-01

Two experiments examined transfer of a prospective, time production skill under conditions involving changes in concurrent task requirements. Positive transfer of the time production skill might be expected only when the attentional demands of the concurrent task were held constant from training to test. However, some positive transfer was found even when the concurrent task at retraining was made either easier or more difficult than the concurrent task learned during training. The amount and direction of transfer depended more on the pacing of the stimuli in the secondary task than on the difficulty of the secondary task, even though difficulty affects attentional demands more. These findings are consistent with the procedural reinstatement principle of skill learning, by which transfer from one task to another depends on an overlap in procedures required by the two skills.

In vitro expansion of human corneal endothelial precursor (HCEP) cells has been reported via production of cell aggregated spheres. However, to translate this procedure in human patients warrants maintaining the position of the eyeballs facing down for 36 h, which is not feasible. In this study, we report a method using a nanocomposite (NC) gel sheet to accomplish the integration of HCEP cells to the endothelium of cadaver bovine's eyes. HCEP cells were isolated from the corneal endothelium of a cadaver human eye and then expanded using a thermoreversible gelation polymer (TGP) as reported earlier. For the study, three cadaver bovine eyes were used. The NC gel sheets were inserted into the bovine eyes', aligned and suture-fixed in position under the host endothelium. HCEP cells previously expanded in the TGP were harvested and injected using a 26-gauge syringe between the endothelium and the NC gel sheet. The eyes were left undisturbed for three hours following which the NC gel sheets were gently removed. The corneas were harvested and subjected to histopathological studies. Histopathological studies showed that all the three corneas used for NC gel sheet implantation showed the presence of engrafted HCEP cells, seen as multi-layered cells over the native endothelium of the bovine cornea. Examination of the NC gel sheets used for implantation showed that only very few corneal endothelial cells remained on the sheets amounting to what could be considered negligible. The use of the NC gel sheet makes HCEP cell transplantation feasible for human patients. Further in vitro basic studies followed by translational studies are necessary to bring this method for clinical application in appropriate indications.

A combined surface/volume scattering retracking algorithm for ice sheet satellite altimetry

NASA Technical Reports Server (NTRS)

Davis, Curt H.

1992-01-01

An algorithm that is based upon a combined surface-volume scattering model is developed. It can be used to retrack individual altimeter waveforms over ice sheets. An iterative least-squares procedure is used to fit the combined model to the return waveforms. The retracking algorithm comprises two distinct sections. The first generates initial model parameter estimates from a filtered altimeter waveform. The second uses the initial estimates, the theoretical model, and the waveform data to generate corrected parameter estimates. This retracking algorithm can be used to assess the accuracy of elevations produced from current retracking algorithms when subsurface volume scattering is present. This is extremely important so that repeated altimeter elevation measurements can be used to accurately detect changes in the mass balance of the ice sheets. By analyzing the distribution of the model parameters over large portions of the ice sheet, regional and seasonal variations in the near-surface properties of the snowpack can be quantified.

Magnetohydrodynamic dissipative flow across the slendering stretching sheet with temperature dependent variable viscosity

The boundary layer flow across a slendering stretching sheet has gotten awesome consideration due to its inexhaustible pragmatic applications in nuclear reactor technology, acoustical components, chemical and manufacturing procedures, for example, polymer extrusion, and machine design. By keeping this in view, we analyzed the two-dimensional MHD flow across a slendering stretching sheet within the sight of variable viscosity and viscous dissipation. The sheet is thought to be convectively warmed. Convective boundary conditions through heat and mass are employed. Similarity transformations used to change over the administering nonlinear partial differential equations as a group of nonlinear ordinary differential equations. Runge-Kutta based shooting technique is utilized to solve the converted equations. Numerical estimations of the physical parameters involved in the problem are calculated for the friction factor, local Nusselt and Sherwood numbers. Viscosity variation parameter and chemical reaction parameter shows the opposite impact to each other on the concentration profile. Heat and mass transfer Biot numbers are helpful to enhance the temperature and concentration respectively.

Diagnosing Expertise: Human Capital, Decision Making, and Performance among Physicians

Currie, Janet; MacLeod, W. Bentley

2017-01-01

Expert performance is often evaluated assuming that good experts have good outcomes. We examine expertise in medicine and develop a model that allows for two dimensions of physician performance: decision making and procedural skill. Better procedural skill increases the use of intensive procedures for everyone, while better decision making results in a reallocation of procedures from fewer low-risk to high-risk cases. We show that poor diagnosticians can be identified using administrative data and that improving decision making improves birth outcomes by reducing C-section rates at the bottom of the risk distribution and increasing them at the top of the distribution.

The research was designed to validate procedures to teach apartment upkeep skills to severely handicapped clients with various categorical disabilities. Methodological features of this research included performance comparisons between general and specific task analyses, effect of an impasse correction baseline procedure, social validation of training goals, natural environment assessments and contingencies, as well as long-term follow-up. Subjects were taught to perform upkeep responses on their air conditioner-heating unit, electric range, refrigerator, and electrical appliances within the context of a multiple-probe across subjects experimental design. The results showed acquisition, long-term maintenance, and generalization of the upkeep skills to a nontraining apartment. General task analyses were recommended for assessment and specific task analyses for training. The impasse correction procedure generally did not produce acquisition. PMID:3710947

Decorating graphene oxide with CuO nanoparticles in a water-isopropanol system.

2010-06-01

A facile chemical procedure capable of aligning CuO nanoparticles on graphene oxide (GO) in a water-isopropanol system has been described. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) observations indicate that the exfoliated GO sheets are decorated randomly by spindly or spherical CuO nanoparticle aggregates, forming well-ordered CuO:GO nanocomposites. A formation mechanism of these interesting nanocomposites is proposed as intercalation and adsorption of Cu2+ ions onto the GO sheets, followed by the nucleation and growth of the CuO crystallites, which in return resulted in the exfoliation of GO sheets. Moreover, the obtained nanocomposites exhibit a high catalytic activity for the thermal decomposition of ammonium perchlorate (AP), due to the concerted effect of CuO and GO.

Assessing residents' operative skills for external ventricular drain placement and shunt surgery in pediatric neurosurgery.

PubMed

Aldave, Guillermo; Hansen, Daniel; Briceño, Valentina; Luerssen, Thomas G; Jea, Andrew

2017-04-01

OBJECTIVE The authors previously demonstrated the use of a validated Objective Structured Assessment of Technical Skills (OSATS) tool for evaluating residents' operative skills in pediatric neurosurgery. However, no benchmarks have been established for specific pediatric procedures despite an increased need for meaningful assessments that can either allow for early intervention for underperforming trainees or allow for proficient residents to progress to conducting operations independently with more passive supervision. This validated methodology and tool for assessment of operative skills for common pediatric neurosurgical procedures-external ventricular drain (EVD) placement and shunt surgery- was applied to establish its procedure-based feasibility and reliability, and to document the effect of repetition on achieving surgical skill proficiency in pediatric EVD placement and shunt surgery. METHODS A procedure-based technical skills assessment for EVD placements and shunt surgeries in pediatric neurosurgery was established through the use of task analysis. The authors enrolled all residents from 3 training programs (Baylor College of Medicine, Houston Methodist Hospital, and University of Texas-Medical Branch) who rotated through pediatric neurosurgery at Texas Children's Hospital over a 26-month period. For each EVD placement or shunt procedure performed with a resident, the faculty and resident (for self-assessment) completed an evaluation form (OSATS) based on a 5-point Likert scale with 7 categories. Data forms were then grouped according to faculty versus resident (self) assessment, length of pediatric neurosurgery rotation, postgraduate year level, and date of evaluation ("beginning of rotation," within 1 month of start date; "end of rotation," within 1 month of completion date; or "middle of rotation"). Descriptive statistical analyses were performed with the commercially available SPSS statistical software package. A p value < 0.05 was considered statistically significant. RESULTS Five attending evaluators (including 2 fellows who acted as attending surgeons) completed 260 evaluations. Twenty house staff completed 269 evaluations for self-assessment. Evaluations were completed in 562 EVD and shunt procedures before the surgeons left the operating room. There were statistically significant differences (p < 0.05) between overall attending (mean 4.3) and junior resident (self; mean 3.6) assessments, and between overall attending (mean 4.8) and senior resident (self; mean 4.6) assessment scores on general performance and technical skills. The learning curves produced for the residents demonstrate a stereotypical U- or V-shaped curve for acquiring skills, with a significant improvement in overall scores at the end of the rotation compared with the beginning. The improvement for junior residents (Δ score = 0.5; p = 0.002) was larger than for senior residents (Δ score = 0.2; p = 0.018). CONCLUSIONS The OSATS is an effective assessment tool as part of a comprehensive evaluation of neurosurgery residents' performance for specific pediatric procedures. The authors observed a U-shaped learning curve, contradicting the idea that developing one's surgical technique and learning a procedure represents a monotonic, cumulative process of repetitions and improvement.

Toolbox of assessment tools of technical skills in otolaryngology-head and neck surgery: A systematic review.

PubMed

Labbé, Mathilde; Young, Meredith; Nguyen, Lily H P

2017-10-08

To support the development of programs of assessment of technical skills in the operating room (OR), we systematically reviewed the literature to identify assessment tools specific to otolaryngology-head and neck surgery (OTL-HNS) core procedures and summarized their characteristics. We systematically searched Embase, MEDLINE, PubMed, and Cochrane to identify and report on assessment tools that can be used to assess residents' technical surgical skills in the operating room for OTL-HNS core procedures. Of the 736 unique titles retrieved, 16 articles met inclusion criteria, covering 11 different procedures (in otology, rhinology, laryngology, head and neck, and general otolaryngology). The tools were composed of a task-specific checklist and/or global rating scale and were developed in the OR, on human cadavers, or in a simulation setting. Our study reports on published tools for assessing technical skills for OTL-HNS residents during core procedures conducted in the OR. These assessment tools could facilitate the provision of timely feedback to trainees including specific goals for improvement. However, the paucity of publications suggests little agreement on how to best perform work-based direct-observation assessment for core surgical procedures in OTL-HNS. The sparsity of tools specific to OTL-HNS may become a barrier to a fluid transition to competency-based medical education.

The importance of non-technical skills in improving surgical safety and performance is now well recognised. Better understanding is needed of the impact that non-technical skills of the multi-disciplinary theatre team have on intra-operative incidents in the operating room (OR) using structured theatre-based assessment. The interaction of non-technical skills that influence surgical safety of the OR team will be explored and made more transparent. Between May-August 2013, a range of procedures in general and vascular surgery in the Royal Infirmary of Edinburgh were performed. Non-technical skills behavioural markers and associated intra-operative incidents were recorded using established behavioural marking systems (NOTSS, ANTS and SPLINTS). Adherence to the surgical safety checklist was also observed. A total of 51 procedures were observed, with 90 recorded incidents - 57 of which were considered avoidable. Poor situational awareness was a common area for surgeons and anaesthetists leading to most intra-operative incidents. Poor communication and teamwork across the whole OR team had a generally large impact on intra-operative incidents. Leadership was shown to be an essential set of skills for the surgeons as demonstrated by the high correlation of poor leadership with intra-operative incidents. Team-working and management skills appeared to be especially important for anaesthetists in the recovery from an intra-operative incident. A significant number of avoidable incidents occur during operative procedures. These can all be linked to failures in non-technical skills. Better training of both individual and team in non-technical skills is needed in order to improve patient safety in the operating room.

Poor awareness among medical graduates about basic life support (BLS) is a matter of great concern. The presence of a trained rescuer is the key determinant of ultimate survival from life-threatening emergencies. To achieve this goal, early exposure to such life-saving skills is the right decision to foster these skills for medical students, which can be reenforced in succeeding years. Forty-two first-year medical students participated in this study. The entire procedure consisted of faculty training, assessment of knowledge of students by a pretest questionnaire, a lecture, a demonstration, and hands-on training using a mannequin (with special emphasis on the site, depth, rate, and sustainment of uninterrupted chest compressions). Posttest 1 was conducted to assess the knowledge gained. The retention of knowledge and skills in the second year was evaluated by posttest 2 and directly observed procedural skills, respectively. Student feedback was collected on five-point Likert scale. Analysis using a Freidman test indicated the mean rank for posttest 1 (2.81) to be significantly higher than the pretest (1.26), indicating a gain in knowledge. The mean rank for posttest 2 (1.93) was lower than for posttest 1 (2.81) but was significantly higher compared with the pretest (1.26), indicating a significant retention of knowledge during the second year. Directly observed procedural skill evaluation showed that 7% students could perform all the seven steps correctly and that 74% students could perform three or more steps correctly, signifying a good retention of skill. Two students taught BLS skills to their family members as well. The results of this study suggest that the program provides students with sound basic knowledge and adequate practical skills in BLS.

Aim To develop and evaluate the use of a specific picture book aiming to prepare children for anaesthesia and surgery. Methods An intervention comparing two different information methods before ear, nose and throat day surgery was performed. The intervention involved using a specific information sheet and a specific picture book. Parents (n=104) of children aged 2-12 years completed open-ended questions that were analysed with qualitative content analysis. They were divided into two groups: one group received routine information and one received routine information and the intervention. Findings The picture sheet and picture book were valuable aids to prepare small children for anaesthesia and surgery by explaining the procedures that would take place. The parents expressed that knowledge of the procedures made them and the child feel secure. Conclusion Peri-operative information through pictures supports children and their parents during day surgery and may be helpful in future healthcare visits.

The feasibility of applying superplastic forming/diffusion bonding (SPF/DB) technology to laminar flow control (LFC) system concepts was demonstrated. Procedures were developed to produce smooth, flat titanium panels, using thin -0.016 inch sheets, meeting LFC surface smoothness requirements. Two large panels 28 x 28 inches were fabricated as final demonstration articles. The first was flat on the top and bottom sides demonstrating the capability of the tooling and the forming and diffusion bonding procedures to produce flat, defect free surfaces. The second panel was configurated for LFC porous panel treatment by forming channels with dimpled projections on the top side. The projections were machined away leaving holes extending into the panel. A perforated titanium sheet was adhesively bonded over this surface to complete the LFC demonstration panel. The final surface was considered flat enough to meet LFC requirements for a jet transport aircraft in cruising flight.

The ultimate goal of surgical training is consolidated skills with a consistently high performance. However, surgical skills are heterogeneously retained and depend on a variety of factors, including the task, cognitive demands, and organization of practice. Virtual reality (VR) simulation is increasingly being used in surgical skills training, including temporal bone surgery, but there is a gap in knowledge on the retention of mastoidectomy skills after VR simulation training. To determine the retention of mastoidectomy skills after VR simulation training with distributed and massed practice and to investigate participants' cognitive load during retention procedures. A prospective 3-month follow-up study of a VR simulation trial was conducted from February 6 to September 19, 2014, at an academic teaching hospital among 36 medical students: 19 from a cohort trained with distributed practice and 17 from a cohort trained with massed practice. Participants performed 2 virtual mastoidectomies in a VR simulator a mean of 3.2 months (range, 2.4-5.0 months) after completing initial training with 12 repeated procedures. Practice blocks were spaced apart in time (distributed), or all procedures were performed in 1 day (massed). Performance of the virtual mastoidectomy as assessed by 2 masked senior otologists using a modified Welling scale, as well as cognitive load as estimated by reaction time to perform a secondary task. Among 36 participants, mastoidectomy final-product skills were largely retained at 3 months (mean change in score, 0.1 points; P = .89) regardless of practice schedule, but the group trained with massed practice took more time to complete the task. The performance of the massed practice group increased significantly from the first to the second retention procedure (mean change, 1.8 points; P = .001), reflecting that skills were less consolidated. For both groups, increases in reaction times in the secondary task (distributed practice group: mean pretraining relative reaction time, 1.42 [95% CI, 1.37-1.47]; mean end of training relative reaction time, 1.24 [95% CI, 1.16-1.32]; and mean retention relative reaction time, 1.36 [95% CI, 1.30-1.42]; massed practice group: mean pretraining relative reaction time, 1.34 [95% CI, 1.28-1.40]; mean end of training relative reaction time, 1.31 [95% CI, 1.21-1.42]; and mean retention relative reaction time, 1.39 [95% CI, 1.31-1.46]) indicated that cognitive load during the virtual procedures had returned to the pretraining level. Mastoidectomy skills acquired under time-distributed practice conditions were retained better than skills acquired under massed practice conditions. Complex psychomotor skills should be regularly reinforced to consolidate both motor and cognitive aspects. Virtual reality simulation training provides the opportunity for such repeated training and should be integrated into training curricula.

The Accreditation Council for Graduate Medical Education core competencies stress nontechnical skills that can be difficult to evaluate and teach to surgical residents. During emergencies, surgeons work in interprofessional teams and are required to perform certain procedures. To obtain proficiency in these skills, residents must be trained. To educate surgical residents in leadership, teamwork, effective communication, and infrequently performed emergency surgical procedures with the use of interprofessional simulations. SimMan 3GS was used to simulate high-risk clinical scenarios (15-20 minutes), followed by debriefings with real-time feedback (30 minutes). A modified Oxford Non-Technical Skills scale (score range, 1-4) was used to assess surgical resident performance during the first half of the academic year (July-December 2012) and the second half of the academic year (January-June 2013). Anonymous online surveys were used to solicit participant feedback. Simulations were conducted in the operating room, intensive care unit, emergency department, ward, and simulation center. A total of 43 surgical residents (postgraduate years [PGYs] 1 and 2) participated in interdisciplinary clinical scenarios, with other health care professionals (nursing, anesthesia, critical care, medicine, respiratory therapy, and pharmacy; mean number of nonsurgical participants/session: 4, range 0-9). Thirty seven surgical residents responded to the survey. Simulation of high-risk clinical scenarios: postoperative pulmonary embolus, pneumothorax, myocardial infarction, gastrointestinal bleeding, anaphylaxis with a difficult airway, and pulseless electrical activity arrest. Evaluation of resident skills: communication, leadership, teamwork, problem solving, situation awareness, and confidence in performing emergency procedures (eg, cricothyroidotomy). A total of 31 of 35 (89%) of the residents responding found the sessions useful. Additionally, 28 of 33 (85%) reported improved confidence doing procedures and 29 of 37 (78%) reported knowing when the procedure should be applied. Oxford Non-Technical Skills evaluation demonstrated significant improvement in PGY 2 resident performance assessed during the 2 study periods: communication score increased from 3 to 3.71 (P=.01), leadership score increased from 2.77 to 3.86 (P<.001), teamwork score increased from 3.15 to 3.86 (P=.007), and procedural ability score increased from 2.23 to 3.43 (P=.03). There were no statistically significant improved scores in PGY 2 decision making or situation awareness. No improvements in skills were seen among PGY 1 participants. The PGY 2 residents improved their skills, but the PGY 1 residents did not. Participants found interprofessional simulations to be realistic and a valuable educational tool. Interprofessional simulation provides a valuable means of educating surgical residents and evaluating their skills in real-life clinical scenarios.

Making a georeferenced mosaic of historical map series using constrained polynomial fit

NASA Astrophysics Data System (ADS)

Molnár, G.

2009-04-01

Present day GIS software packages make it possible to handle several hundreds of rasterised map sheets. For proper usage of such datasets we usually have two requirements: First these map sheets should be georeferenced, secondly these georeferenced maps should fit properly together, without overlap and short. Both requirements can be fulfilled easily, if the geodetic background for the map series is accurate, and the projection of the map series is known. In this case the individual map sheets should be georeferenced in the projected coordinate system of the map series. This means every individual map sheets are georeferenced using overprinted coordinate grid or image corner projected coordinates as ground control points (GCPs). If after this georeferencing procedure the map sheets do not fit together (for example because of using different projection for every map sheet, as it is in the case of Third Military Survey) a common projection can be chosen, and all the georeferenced maps should be transformed to this common projection using a map-to-map transformation. If the geodetic background is not so strong, ie. there are distortions inside the map sheets, a polynomial (linear quadratic or cubic) polynomial fit can be used for georeferencing the map sheets. Finding identical surface objects (as GCPs) on the historical map and on a present day cartographic map, let us to determine a transformation between raw image coordinates (x,y) and the projected coordinates (Easting, Northing, E,N). This means, for all the map sheets, several GCPs should be found, (for linear, quadratic of cubic transformations at least 3, 5 or 10 respectively) and every map sheets should be transformed to a present day coordinate system individually using these GCPs. The disadvantage of this method is that, after the transformation, the individual transformed map sheets not necessarily fit together properly any more. To overcome this problem neither the reverse order of procedure helps: if we make the mosaic first (eg. graphically) and we try the polynomial fit of this mosaic afterwards, neither using this can we reduce the error of internal inaccuracy of the map-sheets. We can overcome this problem by calculating the transformation parameters of polynomial fit with constrains (Mikhail, 1976). The constrain is that the common edge of two neighboring map-sheets should be transformed identically, ie. the right edge of the left image and the left edge of the right image should fit together after the transformation. This condition should fulfill for all the internal (not only the vertical, but also for the horizontal) edges of the mosaic. Constrains are expressed as a relationship between parameters: The parameters of the polynomial transformation should fulfill not only the least squares adjustment criteria but also the constrain: the transformed coordinates should be identical on the image edges. (With the example mentioned above, for image points of the rightmost column of the left image the transformed coordinates should be the same a for the image points of the leftmost column of the right image, and these transformed coordinates can depend on the line number image coordinate of the raster point.) The normal equation system can be calculated with Lagrange-multipliers. The resulting set of parameters for all map-sheets should be applied on the transformation of the images. This parameter set can not been directly applied in GIS software for the transformation. The simplest solution applying this parameters is ‘simulating' GCPs for every image, and applying these simulated GCPs for the georeferencing of the individual map sheets. This method is applied on a set of map-sheets of the First military Survey of the Habsburg Empire with acceptable results. Reference: Mikhail, E. M.: Observations and Least Squares.

Model-based cartilage thickness measurement in the submillimeter range

Current methods of image-based thickness measurement in thin sheet structures utilize second derivative zero crossings to locate the layer boundaries. It is generally acknowledged that the nonzero width of the point spread function (PSF) limits the accuracy of this measurement procedure. We propose a model-based method that strongly reduces PSF-induced bias by incorporating the PSF into the thickness estimation method. We estimated the bias in thickness measurements in simulated thin sheet images as obtained from second derivative zero crossings. To gain insight into the range of sheet thickness where our method is expected to yield improved results, sheet thickness wasmore » varied between 0.15 and 1.2 mm with an assumed PSF as present in the high-resolution modes of current computed tomography (CT) scanners [full width at half maximum (FWHM) 0.5-0.8 mm]. Our model-based method was evaluated in practice by measuring layer thickness from CT images of a phantom mimicking two parallel cartilage layers in an arthrography procedure. CT arthrography images of cadaver wrists were also evaluated, and thickness estimates were compared to those obtained from high-resolution anatomical sections that served as a reference. The thickness estimates from the simulated images reveal that the method based on second derivative zero crossings shows considerable bias for layers in the submillimeter range. This bias is negligible for sheet thickness larger than 1 mm, where the size of the sheet is more than twice the FWHM of the PSF but can be as large as 0.2 mm for a 0.5 mm sheet. The results of the phantom experiments show that the bias is effectively reduced by our method. The deviations from the true thickness, due to random fluctuations induced by quantum noise in the CT images, are of the order of 3% for a standard wrist imaging protocol. In the wrist the submillimeter thickness estimates from the CT arthrography images correspond within 10% to those estimated from the anatomical sections. We present a method that yields virtually unbiased thickness estimates of cartilage layers in the submillimeter range. The good agreement of thickness estimates from CT images with estimates from anatomical sections is promising for clinical application of the method in cartilage integrity staging of the wrist and the ankle.« less

Introduction Over the past decade, medical students have witnessed a decline in the opportunities to perform technical skills during their clinical years. Ultrasound-guided central venous access (USG-CVA) is a critical procedure commonly performed by emergency medicine, anesthesia, and general surgery residents, often during their first month of residency. However, the acquisition of skills required to safely perform this procedure is often deficient upon graduation from medical school. To ameliorate this lack of technical proficiency, ultrasound simulation models have been introduced into undergraduate medical education to train venous access skills. Criticisms of simulation models are the innate lack of realistic tactile qualities, as well as the lack of anatomical variances when compared to living patients. The purpose of our investigation was to design and evaluate a life-like and reproducible training model for USG-CVA using a fresh cadaver. Methods This was a cross-sectional study at an urban academic medical center. An 18-point procedural knowledge tool and an 18-point procedural skill evaluation tool were administered during a cadaver lab at the beginning and end of the surgical clerkship. During the fresh cadaver lab, procedure naïve third-year medical students were trained on how to perform ultrasound-guided central venous access of the femoral and internal jugular vessels. Preparation of the fresh cadaver model involved placement of a thin-walled latex tubing in the anatomic location of the femoral and internal jugular vein respectively. Results Fifty-six third-year medical students participated in this study during their surgical clerkship. The fresh cadaver model provided high quality and lifelike ultrasound images despite numerous cannulation attempts. Technical skill scores improved from an average score of 3 to 12 (p<0.001) and procedural knowledge scores improved from an average score of 4 to 8 (p<0.001). Conclusion The use of this novel cadaver model prevented extravasation of fluid, maintained ultrasound-imaging quality, and proved to be an effective educational model allowing third-year medical students to improve and maintain their technical skills.

In a traditional curriculum, medical students are expected to acquire clinical competence through the apprenticeship model using the Halstedian "see one, do one, and teach one, approach". The University of Zambia School of Medicine used a traditional curriculum model from 1966 until 2011 when a competence-based curriculum was implemented. To explore medical students' clerkships experiences and self-perceived competence in clinical skills. A cross-sectional survey was conducted on 5th, 6 th , and 7 th year medical students of the University of Zambia, School of Medicine two months prior to final examinations. Students were asked to rate their clerkship experiences with respect to specific skills on a scale of 1 to 4 and their level of self-perceived competence on a scale of 1 to 3. Skills evaluated were in four main domains: history taking and communication, physical examination, procedural, and professionalism, team work and medical decision making. Using Statistical Package for Social Scientist (SPSS), correlations were performed between experiences and self-perceived competence on specific skills, within domains and overall. Out of 197 clinical students 138 (70%) participated in the survey. The results showed significant increase in the proportion of students performing different skills and reporting feeling very competent with each additional clinical year. Overall correlations between experience and self-perceived competence were moderate (0.55). On individual skills, the highest correlation between experience and self-perceived competence were observed on mainly medical and surgical related procedural skills with the highest at 0.82 for nasal gastric tube insertion and 0.76 for endotracheal intubation. Despite the general improvement in skills experiences and self-perceived competence, some deficiencies were noted as significant numbers of final year students had never attempted common important procedures especially those performed in emergency situations. Deficiencies in certain skills may call for incorporation of teaching/learning methods that broaden students' exposure to such skills.

Background and Aims: Pre-operative negative valence communications adversely affect intra and post-operative pain experience. This study was conducted to evaluate the teaching of communication skills by teachers in anaesthesia department and whether the post-operative pain is effectively modified due to the skill of communication acquired by students. Methods: All students and teachers in the department participated in the study. Patients with uncomplicated pregnancy posted for elective lower segment caesarean section were involved. Students were taught to explain the anaesthesia plan pre-operatively to the patients in a positive manner. They were taught the practice of giving positive suggestions before any potentially painful stimulus. Pre-operatively all students informed the patients about the conduct of spinal anaesthesia. The teachers evaluated the students performing spinal block. The performance was rated for procedural and interpersonal skills (direct observation of procedural skills [DOPS] and Smith and Kendall Behavioural scale [SKBS] respectively). The extent of cooperation and the ease with which spinal block could be administered correctly by the student was judged by the teacher. Post-operatively students were randomly provided questionnaires to elicit answers from patients. Results: P value DOPS and SKBS (0.567, 0.867) show no significant statistical variation. P > 0.05 = not significant, indicates no significant variation in procedural and behavioural skills of students in two groups. Conclusion: Teaching of communication skills to students showed a demonstrable effect on their pre-operative dialogue with patients. Pain mechanism was effectively modulated by improving patients’ psychology to undergo anaesthesia. PMID:26195834

Performing endovascular procedures requires good control of fine-motor digital movements and hand-eye coordination. Objective assessment of such skills is difficult. Trainees acquire control of catheter/wire movements at various paces. However, little is known to what extent talent plays for novice candidates at entry to practice. To study the association between performance in a novel aptitude test of fine-motor skills and performance in simulated procedures. The test was based on manual course-tracking using a proprietary hand-operated roller-bar device coupled to a personal computer with monitor view rotation. A total of 40 test repetitions were conducted separately with each hand. Test scores were correlated with simulator performance. Group A (n = 14), clinicians with various levels of endovascular experience, performed a simulated procedure of contralateral iliac artery stenting. Group B (n = 19), medical students, performed 10 repetitions of crossing a challenging aortic bifurcation in a simulator. The test score differed markedly between the individuals in both groups, in particular with the non-dominant hand. Group A: the test score with the non-dominant hand correlated significantly with simulator performance assessed with the global rating scale SAVE (R = -0.69, P = 0.007). There was no association observed from performances with the dominant hand. Group B: there was no significant association between the test score and endovascular skills acquisition neither with the dominant nor with the non-dominant hand. Clinicians with increasing levels of endovascular technical experience had developed good fine-motor control of the non-dominant hand, in particular, that was associated with good procedural performance in the simulator. The aptitude test did not predict endovascular skills acquisition among medical students, thus, cannot be suggested for selection of novice candidates. Procedural experience and practice probably supplant the influence of innate abilities (talent) over time.

To investigate the effectiveness of the video prompting procedure on teaching aquatic play skills and to determine the effects of aquatic exercise training on the motor performance of children with autism. A multiple probe design across behaviours was used and replicated across subjects for the instructional part of this study. Pretest-posttest design was applied for the exercise training part of this study. Three children with autism were taught three aquatic play skills in a one-to-one training format. Aquatic play skills intervention and aquatic exercise training were performed separately throughout 12 weeks at three sessions per week, each lasting 1 h. The video prompting procedure was utilized for the instruction part of this study. Video prompting was effective in teaching aquatic play skills to children with autism. In addition, aquatic exercise training increased the total motor performance scores of all the participants after 12 weeks. According to the social validity results, the families gave positive feedback about the learned skills and movement capabilities of their children. Aquatic play skills and swimming pools are favoured for children with autism. This attractive intervention is recommended as a means to extend knowledge of leisure skills and motor development of children with autism.

Gureasko-Moore, Sammi; Dupaul, George J; White, George P

2006-03-01

Self-management procedures have been used in school settings to successfully reduce problem behaviors, as well as to reinforce appropriate behavior. A multiple-baseline across participants design was applied in this study to evaluate the effects of using a self-management procedure to enhance the classroom preparation skills of secondary school students with attention-deficit/ hyperactivity disorder (ADHD). Three male students enrolled in a public secondary school were selected for this study because teacher reports suggested that these students were insufficiently prepared for class and inconsistently completed assignments. The intervention involved training in self-management procedures focusing on the improvement of classroom preparation skills. Following the intervention, the training process was systematically faded. Results were consistent across the 3 participants in enhancing classroom preparation behaviors. Implications for practice and future research are discussed.

On contact modelling in isogeometric analysis

NASA Astrophysics Data System (ADS)

Cardoso, R. P. R.; Adetoro, O. B.

2017-11-01

IsoGeometric Analysis (IGA) has proved to be a reliable numerical tool for the simulation of structural behaviour and fluid mechanics. The main reasons for this popularity are essentially due to: (i) the possibility of using higher order polynomials for the basis functions; (ii) the high convergence rates possible to achieve; (iii) the possibility to operate directly on CAD geometry without the need to resort to a mesh of elements. The major drawback of IGA is the non-interpolatory characteristic of the basis functions, which adds a difficulty in handling essential boundary conditions and makes it particularly challenging for contact analysis. In this work, the IGA is expanded to include frictionless contact procedures for sheet metal forming analyses. Non-Uniform Rational B-Splines (NURBS) are going to be used for the modelling of rigid tools as well as for the modelling of the deformable blank sheet. The contact methods developed are based on a two-step contact search scheme, where during the first step a global search algorithm is used for the allocation of contact knots into potential contact faces and a second (local) contact search scheme where point inversion techniques are used for the calculation of the contact penetration gap. For completeness, elastoplastic procedures are also included for a proper description of the entire IGA of sheet metal forming processes.

Zinc alloys are used in a wide range of application such as electronics, automotive and building construction. Their various shapes are generally obtained by metal forming operation such as stamping. Therefore, it is important to characterize the material with adequate characterization tests. Sheet Bulging Test (SBT) is well recognized in the metal forming community. Different theoretical models of the literature for the evaluation of thickness and radius of the deformed sheet in SBT have been studied in order to get the hardening curve of different materials. These theoretical models present the advantage that the experimental procedure is very simple. But Koç et al. showed their limitation, since the combination of thickness and radius evaluations depend on the material. As Zinc alloys are strongly anisotropic with a special crystalline structure, a procedure is adopted for characterizing the hardening curve of a Zinc alloy. The anisotropy is first studied with tensile test, and SBT with elliptical dies is also investigated. Parallel to this, Digital Image Correlation (DIC) measures are carried out. The results obtained from theoretical models and DIC measures are compared. Measures done on post-mortem specimens complete the comparisons. Finally, DIC measures give better results and the resulting hardening curve of the studied zinc alloy is provided.

Surgical resident ability to accurately evaluate one's own skill level is an important part of educational growth. We aimed to determine if differences exist between self and observer technical skill evaluation of surgical residents performing a single procedure. We prospectively enrolled 14 categorical general surgery residents (six post-graduate year [PGY] 1-2, three PGY 3, and five PGY 4-5). Over a 6-month period, following each laparoscopic cholecystectomy, residents and seven faculty each completed the Objective Structured Assessment of Technical Skills (OSATS). Spearman's coefficient was calculated for three groups: senior (PGY 4-5), PGY3, and junior (PGY 1-2). Rho (ρ) values greater than 0.8 were considered well correlated. Of the 125 paired assessments (resident-faculty each evaluating the same case), 58 were completed for senior residents, 54 for PGY3 residents, and 13 for junior residents. Using the mean from all OSATS categories, trainee self-evaluations correlated well to faculty (senior ρ 0.97, PGY3 ρ 0.9, junior ρ 0.9). When specific OSATS categories were analyzed, junior residents exhibited poor correlation in categories of respect for tissue (ρ -0.5), instrument handling (ρ 0.71), operative flow (ρ 0.41), use of assistants (ρ 0.05), procedural knowledge (ρ 0.32), and overall comfort with the procedure (ρ 0.73). PGY3 residents lacked correlation in two OSATS categories, operative flow (ρ 0.7) and procedural knowledge (ρ 0.2). Senior resident self-evaluations exhibited strong correlations to observers in all areas. Surgical residents improve technical skill self-awareness with progressive training. Less-experienced trainees have a tendency to over-or-underestimate technical skill. Copyright © 2017 Elsevier Inc. All rights reserved.

This study aims to enhance chemistry students’ creative thinking skills using material from local resources on protein qualitative test experiment (LMBE). In this study, a quasi experiment method using one group pretest-postest non-equivalen control group design was carried out on the effectiveness of local material-based experiment approach. The data was collected using the test consists of five assay test and student work sheet (LKM). The effectiveness of the local material-based experiment was tested by means of percentage of normalized gain and score percentage of students’ worksheet. Comparison of creative thinking skills pretest and postest scores showed that the implementation of local material- based experiment (LMBE) enhanced students’s creative thinking skills in experiment class with the value of normalized gain (=0,77) at high category, while in control class reached to =0,44 at medium category. In addition, the LKM shown the enhancements of all aspect of creative thinking skills, including fluency, flexibility, and elaboration skills with the score of in experiment class are 0.79; 0.75; and 0.87 at high category, respectively. In contrast, the only the elaboration skill of control group was improved at high category (=0.76), while fluency and flexibility indicators enhanced at medium category (=0.48 and 0.56, respectively).

Oil canning is predominantly caused by unequal stretches and heterogeneous stress distributions in steel sheets, which affects the appearance of components and develop noise and vibration problems. This paper proposes the formulation of an Oil canning index (OCI) model that can predict the occurrence of oil canning in the sheet metal. To investigate the influence of material properties, we used electro-galvanized (EGI) and galvanized (GI) steel sheets with different thicknesses and processing conditions. Furthermore, this paper presents an appropriate experimental and numerical procedure for determining the sheet stiffness and indentation properties to evaluate the oil canning results. Experiments were carried out by varying the tensile force over different materials, thicknesses, and bead force. Comparison of the discrete results obtained from these experiments confirmed that the product shape characteristics, such as curvature, have a significant influence on the oil canning occurrence. Based on the results, we propose the new OCI model, which can effectively predict the oil canning occurrence owing to the shape curvature. Verification of the accuracy and usability of our model has been carried out by simulating the experiments that were done with the sheet metal. The authors observed a good agreement between the experimental and numerical results from the model. This research work can be considered as a very effective method for eliminating appearance defects from the automobile products.

There is no comprehensive simulation-enhanced training curriculum to address cognitive, psychomotor, and nontechnical skills for an advanced minimally invasive procedure. 1) To develop and provide evidence of validity for a comprehensive simulation-enhanced training (SET) curriculum for an advanced minimally invasive procedure; (2) to demonstrate transfer of acquired psychomotor skills from a simulation laboratory to live porcine model; and (3) to compare training outcomes of SET curriculum group and chief resident group. University. This prospective single-blinded, randomized, controlled trial allocated 20 intermediate-level surgery residents to receive either conventional training (control) or SET curriculum training (intervention). The SET curriculum consisted of cognitive, psychomotor, and nontechnical training modules. Psychomotor skills in a live anesthetized porcine model in the OR was the primary outcome. Knowledge of advanced minimally invasive and bariatric surgery and nontechnical skills in a simulated OR crisis scenario were the secondary outcomes. Residents in the SET curriculum group went on to perform a laparoscopic jejunojejunostomy in the OR. Cognitive, psychomotor, and nontechnical skills of SET curriculum group were also compared to a group of 12 chief surgery residents. SET curriculum group demonstrated superior psychomotor skills in a live porcine model (56 [47-62] versus 44 [38-53], P<.05) and superior nontechnical skills (41 [38-45] versus 31 [24-40], P<.01) compared with conventional training group. SET curriculum group and conventional training group demonstrated equivalent knowledge (14 [12-15] versus 13 [11-15], P = 0.47). SET curriculum group demonstrated equivalent psychomotor skills in the live porcine model and in the OR in a human patient (56 [47-62] versus 63 [61-68]; P = .21). SET curriculum group demonstrated inferior knowledge (13 [11-15] versus 16 [14-16]; P<.05), equivalent psychomotor skill (63 [61-68] versus 68 [62-74]; P = .50), and superior nontechnical skills (41 [38-45] versus 34 [27-35], P<.01) compared with chief resident group. Completion of the SET curriculum resulted in superior training outcomes, compared with conventional surgery training. Implementation of the SET curriculum can standardize training for an advanced minimally invasive procedure and can ensure that comprehensive proficiency milestones are met before exposure to patient care.

There was no difference in the acceptance of a general personality interpretation supposedly based on psychological, graphological, or astrological assessment procedures. Ss told that their general personality interpretation was based on one of the three assessment procedures, however, accepted the interpretation to a greater degree than did Ss told the interpretation was "generally true of people." S faith in all assessment procedures and perceived diagnostician skill increased significantly from before to after receipt of the diagnostic feedback. Ss elicited a halo response after they had received the interpretation, such that they generated a highly consistent positive (or negative) view of the assessment procedures and diagnostician skills. Implications of results from this acceptance paradigm were discussed for diagnosticians and therapists.

We previously reported that cell sheet transplantation combined with an omentopexy (OP) procedure is more effective for repairing heart damage when compared with cell sheet transplantation alone. However, a simultaneous (conventional) laparotomy as part of the OP may adversely affect the general condition of critically ill heart failure patients who would otherwise benefit from cell sheet transplantation, which is a paradox to be reconciled before this treatment can be applied in a clinical setting. We devised a novel endoscopic approach termed 'transphrenic peritoneoscopy' (TPP) for minimal access to abdominal organs from the thoracic cavity. Herein, we evaluated the feasibility and safety of TPP with an OP in a porcine myocardial infarction model. Myocardial infarction was induced in 4 mini pigs by placing an ameroid constrictor around the left anterior descending artery. One month later, a left thoracotomy was performed in 2 randomly selected mini pigs, and a laparoscopic port was placed on the left diaphragm to gain access into the abdominal cavity. Using a low-pressure pneumoperitoneum, a flexible gastrointestinal endoscope was advanced, then the omentum was partially grasped with endoscopic forceps and brought back into the thoracic cavity via the diaphragm. Skeletal myoblast cell sheets were then implanted over the impaired myocardium, followed by placing the omentum over the sheets. TPP-assisted OP was accomplished in 2 post-myocardial infarction mini pigs with severe heart failure with an intra-abdominal pressure ≤8 mmHg within 30 min (22 and 27 min, respectively). Necropsy findings revealed a viable omentum flap and pedicle in both animals, with no evidence of procedure-related complications. Angiographic and histological analyses confirmed vessel communication between the omentum and the left ventricle. Our TPP approach was shown to be feasible and safe with a low-pressure pneumoperitoneum, while the omentum flap was durable. This successful combination of techniques may provide less-invasive endoscopic intervention and regenerative therapy.

Analysis of Welding Zinc Coated Steel Sheets in Zero Gap Configuration by 3D Simulations and High Speed Imaging

NASA Astrophysics Data System (ADS)

Koch, Holger; Kägeler, Christian; Otto, Andreas; Schmidt, Michael

Welding of zinc coated sheets in zero gap configuration is of eminent interest for the automotive industry. This Laser welding process would enable the automotive industry to build auto bodies with a high durability in a plain manufacturing process. Today good welding results can only be achieved by expensive constructive procedures such as clamping devices to ensure a defined gad. The welding in zero gap configuration is a big challenge because of the vaporised zinc expelled from the interface between the two sheets. To find appropriate welding parameters for influencing the keyhole and melt pool dynamics, a three dimensional simulation and a high speed imaging system for laser keyhole welding have been developed. The obtained results help to understand the process of the melt pool perturbation caused by vaporised zinc.

2011-11-01

This study conducted at the PDM Dental College and Research Institute, Haryana, India, had the purpose of developing a teaching method based upon a five-step method for teaching clinical skills to students proposed by the American College of Surgeons. This five-step teaching method was used to place fissure sealants as an initial procedure by dental students in clinics. The sealant retention was used as an objective evaluation of the skill learnt by the students. The sealant retention was 92 percent at six- and twelve-month evaluations and 90 percent at the eighteen-month evaluation. These results indicate that simple methods can be devised for teaching clinical skills and achieve high success rates in clinical procedures requiring multiple steps.

   Advanced surgical procedures, which have become complex and difficult, increase the burden of surgeons. Quantitative analysis of surgical procedures can improve training, reduce variability, and enable optimization of surgical procedures. To this end, a surgical task analysis system was developed that uses only surgical navigation information.    Division of the surgical procedure, task progress analysis, and task efficiency analysis were done. First, the procedure was divided into five stages. Second, the operating time and progress rate were recorded to document task progress during specific stages, including the dissecting task. Third, the speed of the surgical instrument motion (mean velocity and acceleration), as well as the size and overlap ratio of the approximate ellipse of the location log data distribution, was computed to estimate the task efficiency during each stage. These analysis methods were evaluated based on experimental validation with two groups of surgeons, i.e., skilled and "other" surgeons. The performance metrics and analytical parameters included incidents during the operation, the surgical environment, and the surgeon's skills or habits.    Comparison of groups revealed that skilled surgeons tended to perform the procedure in less time and involved smaller regions; they also manipulated the surgical instruments more gently.    Surgical task analysis developed for quantitative assessment of surgical procedures and surgical performance may provide practical methods and metrics for objective evaluation of surgical expertise.

Using newly deceased patients in teaching clinical skills: its ethical and educational challenges.

The newly deceased patients have long been used in medical schools to teach clinical skills without any challenges as it helps to train skilled doctors. Nowadays, the use of moulages and simulators are common in teaching clinical skills since these tools provide the opportunity for frequent practice without any pain and injury. There are specific procedures which still require the use of cadavers. However, the increased significance of patient rights has generally challenged the practicality of using the deceased bodies for this purpose. This study was designed with the aim of determining to what extent clinical skill training is dependent on the recently deceased patients. This was a cross-sectional mixed-method triangulation design conducted in two phases. In the first phase, a researcher-made questionnaire was used to collect quantitative data of the medical students and residents. The data were used to assess the frequency of experience. In the second stage, semi-structured interviews were conducted with faculty members and fellows in order to evaluate the educational impact of this type of procedure and the influential factors. The quantitative data were analyzed using statistical software, and the qualitative codes were extracted following a content analysis. Finally, a comparative analysis was performed. Twenty five residents (26%) and seven medical students (14%) had the experience of performing procedures on the recently deceased patients for training purposes. About half of the residents and 33% of the medical students had observed their colleagues practicing procedures on cadavers. In the qualitative phase, the main categories included professional ethics, law and educational requirements. A relatively low number of medical students and residents had experienced procedures on the newly deceased patients. In this regard, ethical, religious and legal concerns might have played a part despite the desire to learn. It would be effective to direct these educational experiences toward procedures that cannot be mastered through moulages and simulators, and to lay the legal and executive ground so that performing these procedures under the supervision of professors, and with a level of documentation would have no legal challenges.

As many preschoolers are not able to cooperate with health-related invasive procedures, sedation can help with the child's comfort and allow the intervention to be done. It is scarcely known how parents affect children's behavior during dental treatment under conscious sedation. The aim of this exploratory study was to analyze the association between mother-child interactions in day-to-day family life and preschool children's behavior during dental treatment under conscious sedation. This cross-sectional study included 27 children aged 2-6 years and their mothers. The children's behavior during dental treatment under conscious sedation was verified through the analysis of videos and using an observational scale. Social skills of mothers were verified through interviews using the Parental Educative Social Skills Interview Script (RE-HSE-P); the sum of the scores allowed the establishment of the categories "clinical" and "non-clinical". We presented descriptive analyses and bivariate associations. Children's overall behavior during dental sedation was: very poor (n = 2), poor (n = 1), regular (n = 2), good (n = 9), very good (n = 9) and excellent (n = 4). Social skills varied: parental educational social skills (n = 24 clinical vs. n = 3 non-clinical); child social skills (n = 20 vs. n = 7), context variables (n = 15 vs. n = 12), negative educational practices (n = 12 vs. n = 15), child behavior problems (n = 7 vs. n = 20). There was no association between child behavior under sedation and social skills categories (P > 0.05). The majority of interviewed mothers reported issues in parental educational social skills and child social skills, which did not affect the outcomes of the children's behavior during the procedural conscious sedation.

Simulation-based medical education (SBME) offers opportunities for trainees to learn how to perform procedures and to be assessed in a safe environment. However, SBME research studies often lack robust evidence to support the validity of the interpretation of the results obtained from tools used to assess trainees' skills. The purpose of this paper is to describe how a validity framework can be applied when reporting and interpreting the results of a simulation-based assessment of skills related to performing procedures. The authors discuss various sources of validity evidence because they relate to SBME. A case study is presented.

Contemporary plastic surgery residents are increasingly challenged to learn a greater number of complex surgical techniques within a limited period. Surgical simulation and digital education resources have the potential to address some limitations of the traditional training model, and have been shown to accelerate knowledge and skills acquisition. Although animal, cadaver, and bench models are widely used for skills and procedure-specific training, digital simulation has not been fully embraced within plastic surgery. Digital educational resources may play a future role in a multistage strategy for skills and procedures training. The authors present two virtual surgical simulators addressing procedural cognition for cleft repair and craniofacial surgery. Furthermore, the authors describe how partnerships among surgical educators, industry, and philanthropy can be a successful strategy for the development and maintenance of digital simulators and educational resources relevant to plastic surgery training. It is our responsibility as surgical educators not only to create these resources, but to demonstrate their utility for enhanced trainee knowledge and technical skills development. Currently available digital resources should be evaluated in partnership with plastic surgery educational societies to guide trainees and practitioners toward effective digital content.

Changes in health care are stimulating residency training programs to develop new methods for teaching surgical skills. We developed Computer-Enhanced Visual Learning (CEVL) as an innovative Internet-based learning and assessment tool. The CEVL method uses the educational procedures of deliberate practice and performance to teach and learn surgery in a stylized manner. CEVL is a learning and assessment tool that can provide students and educators with quantitative feedback on learning a specific surgical procedure. Methods involved examine quantitative data of improvement in surgical skills. Herein, we qualitatively describe the method and show how program directors (PDs) may implement this technique in their residencies. CEVL allows an operation to be broken down into teachable components. The process relies on feedback and remediation to improve performance, with a focus on learning that is applicable to the next case being performed. CEVL has been shown to be effective for teaching pediatric orchiopexy and is being adapted to additional adult and pediatric procedures and to office examination skills. The CEVL method is available to other residency training programs.

Herein, we qualitatively describe the method and show how program directors (PDs) may implement this technique in their residencies. Results CEVL allows an operation to be broken down into teachable components. The process relies on feedback and remediation to improve performance, with a focus on learning that is applicable to the next case being performed. CEVL has been shown to be effective for teaching pediatric orchiopexy and is being adapted to additional adult and pediatric procedures and to office examination skills. The CEVL method is available to other residency training programs. PMID:21975716

Henn, Philipp; Liewald, Mathias; Sindel, Manfred

2017-10-01

This paper presents a new approach to characterise material ductility when combined, three dimensional loading conditions occurring during vehicle crash are applied. So called "axial crush test" of closed hat sections is simplified by reducing it down to a two-dimensional testing procedure. This newly developed edge-compression test (ECT) provides the opportunity to investigate a defined characteristic axial folding behaviour of a profile edge. The potential to quantify and to differentiate crashworthiness of material by use of new edge-compression test is investigated by carrying out experimental studies with two different 6xxx-aluminium sheet alloys.

Just-in-time (JIT) training refers to education occurring immediately prior to clinical encounters. An in situ JIT room in a pediatric emergency department (ED) was created for procedural education. We examined trainee self-reported JIT room use, its impact on trainee self-perception of procedural competence/confidence, and the effect its usage has on the need for intervention by supervising physicians during procedures. Cross-sectional survey study of a convenience sample of residents rotating through the ED and supervising pediatric emergency medicine physicians. Outcomes included JIT room use, trainee procedural confidence, and frequency of supervisor intervention during procedures. Thirty-one of 32 supervising physicians (97%) and 122 of 186 residents (66%) completed the survey, with 71% of trainees reporting improved confidence, and 68% reporting improved procedural skills ( P  < .05, +1.4-point average skills improvement on a 5-point Likert scale). Trainees perceived no difference among supervising physicians intervening in procedures with or without JIT room use ( P  = .30, paired difference -0.0 points). Nearly all supervisors reported improved trainee procedural confidence, and 77% reported improved trainee procedural skills after JIT room use ( P  < .05, paired difference +1.8 points); 58% of supervisors stated they intervene in procedures without trainee JIT room use, compared with 42% with JIT room use ( P  < .05, paired difference -0.4 points). Use of the JIT room led to improved trainee confidence and supervisor reports of less procedural intervention. Although it carries financial and time costs, an in situ JIT room may be important for convenient JIT training.

Venepuncture and the insertion of peripheral venous catheters are common tasks in health care, and training in these procedures is included in nursing programmes. Evidence of nursing students' knowledge and skills in these procedures is limited. The main aim of this study was to assess nursing students' knowledge and skills when performing venepuncture and inserting peripheral venous catheters. Potential associations between level of knowledge and skills, self-training, self-efficacy, and demographic characteristics were also investigated. The assessment was performed by lecturers at a university college in Sweden using the two previously tested instruments "Assess Venepuncture" and "Assess Peripheral Venous Catheter Insertion". Between 81% and 100% of steps were carried out correctly by the students. The step with the highest rating was "Uses gloves", and lowest rating was 'Informs the patients about the possibility of obtaining local anaesthesia'. Significant correlations between degree of self-training and correct performance were found in the group of students who registered their self-training. No associations between demographic characteristics and correct performances were found. Assessing that students have achieved adequate levels of knowledge and skills in these procedures at different levels of the nursing education is of importance to prevent complications and support patient safety.

2005-01-01

Background: High-risk organizations such as aviation rely on simulations for the training and assessment of technical and team performance. The aim of this study was to develop a simulated environment for surgical trainees using similar principles. Methods: A total of 27 surgical trainees carried out a simulated procedure in a Simulated Operating Theatre with a standardized OR team. Observation of OR events was carried out by an unobtrusive data collection system: clinical data recorder. Assessment of performance consisted of blinded rating of technical skills, a checklist of technical events, an assessment of communication, and a global rating of team skills by a human factors expert and trained surgical research fellows. The participants underwent a debriefing session, and the face validity of the simulated environment was evaluated. Results: While technical skills rating discriminated between surgeons according to experience (P = 0.002), there were no differences in terms of the checklist and team skills (P = 0.70). While all trainees were observed to gown/glove and handle sharps correctly, low scores were observed for some key features of communication with other team members. Low scores were obtained by the entire cohort for vigilance. Interobserver reliability was 0.90 and 0.89 for technical and team skills ratings. Conclusions: The simulated operating theatre could serve as an environment for the development of surgical competence among surgical trainees. Objective, structured, and multimodal assessment of performance during simulated procedures could serve as a basis for focused feedback during training of technical and team skills. PMID:16244534

Despite increased use of robotic catheter navigation systems for endovascular intervention procedures, current master-slave platforms have not yet taken into account dexterous manipulation skill used in traditional catheterization procedures. Information on tool forces applied by operators is often limited. A novel force/torque sensor is developed in this paper to obtain behavioural data across different experience levels and identify underlying factors that affect overall operator performance. The miniature device can be attached to any part of the proximal end of the catheter, together with a position sensor attached to the catheter tip, for relating tool forces to catheter dynamics and overall performance. The results show clear differences in manipulation skills between experience groups, thus providing insights into different patterns and range of forces applied during routine endovascular procedures. They also provide important design specifications for ergonomically optimized catheter manipulation platforms with added haptic feedback while maintaining natural skills of the operators.

Carotid stenting is a minimally invasive treatment for extracranial carotid artery stenosis. Stent design may affect technical success and complications in a certain subgroup of patients. We examined the wall adaptability of a new closed-cell carotid stent (NexStent), which has a unique rolled sheet design. Forty-one patients had 42 carotid arteries treated with angioplasty and stenting for internal carotid artery stenosis. The mean patient age was 65 {+-} 10 years. All patients underwent high-resolution computed tomographic angiography after the stent implantation. Data analysis included pre- and postprocedural stenosis, procedure complications, plaque calcification, and stent apposition. We reviewed the angiographic andmore » computed tomographic images for plaque coverage and stent expansion. All procedures were technically successful. Mean stenosis was reduced from 84 {+-} 8% before the procedure to 15.7 {+-} 7% after stenting. Two patients experienced transient ischemic attack; one patient had bradycardia and hypotension. Stent induced kinking was observed in one case. Good plaque coverage and proper overlapping of the rolled sheet was achieved in all cases. There was weak correlation between the residual stenosis and the amount of calcification. The stent provides adequate expansion and adaptation to the tapering anatomy of the bifurcation.« less

2017-09-01

This study is a preliminary research aiming at exploring pre-service physics teachers’ skills in applying the stage of problem-solving strategies. A total of 76 students of physics education study program at a college in Bengkulu Indonesia participated in the study. The skills on solving physics problems are being explored through exercises that demand the use of problem-solving strategies with several stages such as useful description, physics approach, specific application of physics, physics equation, mathematical procedures, and logical progression. Based on the results of data analysis, it is found that the pre-service physics teachers’ skills are in the moderate category for physics approach and mathematical procedural, and low category for the others. It was concluded that the pre-service physics teachers’ problem-solving skills are categorized low. It is caused by the learning of physics that has done less to practice problem-solving skills. The problems provided are only routine and poorly trained in the implementation of problem-solving strategies.The results of the research can be used as a reference for the importance of the development of physics learning based on higher order thinking skills.

2016-02-01

Video review of surgical skills is an educational modality that allows trainees to reflect on self-performance. The purpose of this study was to determine whether resident and attending assessments of a resident's laparoscopic performance differ and whether video review changes assessments. Third-year surgery residents were invited to participate. Elective laparoscopic procedures were video recorded. The Global Operative Assessment of Laparoscopic Skills evaluation was completed immediately after the procedure and again 7 to 10 days later by both resident and attending. Scores were compared using t tests. Nine residents participated and 76 video reviews were completed. Residents scored themselves significantly lower than the faculty scores both before and after video review. Resident scores did not change significantly after video review. Attending and resident self-assessment of laparoscopic skills differs and subsequent video review does not significantly affect Global Operative Assessment of Laparoscopic Skills scores. Further studies should evaluate the impact of video review combined with verbal feedback on skill acquisition and assessment. Copyright © 2016 Elsevier Inc. All rights reserved.

To assess communication skills in children with spastic diplegia. The study included 20 subjects, 10 preschool children with spastic diplegia and 10 typical matched according to gender, mental age, and socioeconomic status. Assessment procedures were the following: interviews with parents, Stanford - Binet method, Gross Motor Function Classification System, Observing the Communicative Behavior, Vocabulary Test by Peabody Picture, Denver Developmental Screening Test II, MacArthur Development Inventory on Communicative Skills. Statistical analysis was performed using the values of mean, median, minimum and maximum value, and using Student's t-test, Mann-Whitney test, and Paired t-test. Individuals with spastic diplegia, when compared to their peers of the same mental age, presented no significant difference in relation to receptive and expressive vocabulary, fine motor skills, adaptive, personal-social, and language. The most affected area was the gross motor skills in individuals with spastic cerebral palsy. The participation in intervention procedures and the pairing of participants according to mental age may have approximated the performance between groups. There was no statistically significant difference in the comparison between groups, showing appropriate communication skills, although the experimental group has not behaved homogeneously.

Use of a spread sheet to calculate the current-density distribution produced in human and rat models by low-frequency electric fields.

PubMed

Hart, F X

1990-01-01

The current-density distribution produced inside irregularly shaped, homogeneous human and rat models by low-frequency electric fields is obtained by a two-stage finite-difference procedure. In the first stage the model is assumed to be equipotential. Laplace's equation is solved by iteration in the external region to obtain the capacitive-current densities at the model's surface elements. These values then provide the boundary conditions for the second-stage relaxation solution, which yields the internal current-density distribution. Calculations were performed with the Excel spread-sheet program on a Macintosh-II microcomputer. A spread sheet is a two-dimensional array of cells. Each cell of the sheet can represent a square element of space. Equations relating the values of the cells can represent the relationships between the potentials in the corresponding spatial elements. Extension to three dimensions is readily made. Good agreement was obtained with current densities measured on human models with both, one, or no legs grounded and on rat models in four different grounding configurations. The results also compared well with predictions of more sophisticated numerical analyses. Spread sheets can provide an inexpensive and relatively simple means to perform good, approximate dosimetric calculations on irregularly shaped objects.

A new tensile impact test for the toughness characterization of sheet material

NASA Astrophysics Data System (ADS)

Könemann, Markus; Lenz, David; Brinnel, Victoria; Münstermann, Sebastian

2018-05-01

In the past, the selection of suitable steels has been carried out primarily based on the mechanical properties of different steels. One of these properties is the resistance against crack propagation. For many constructions, this value plays an important role, because it can compare the impact toughness of different steel grades easily and gives information about the loading capacity of the specific materials. For thin sheets, impact toughness properties were usually not considered. One of the reasons for this is that the Charpy-impact test is not applicable for sheets with thicknesses below 2 mm. For a long time, this was not relevant because conventional steels had a sufficient impact toughness in a wide temperature range. However, since new multiphase steel grades with improved mechanical property exploitations are available, it turned out that impact toughness properties need to be considered during the component design phase, as the activation of the cleavage fracture mechanism is observed under challenging loading conditions. Therefore, this work aims to provide a new and practical testing procedure for sheet material or thin walled structures. The new testing procedure is based on tensile tests conducted in an impact pendulum similar to the Charpy impact hammer. A new standard geometry is provided, which enables a comparison between different steels or steel grades. A connection to the conventional Charpy test is presented using a damage mechanics model, which predicts material failure with consideration of to the stress state at various temperatures. Different specimen geometries are analysed to cover manifold stress states. A special advantage of the damage mechanics model is also the possibility to predict the materials behaviour in the transition area. To verify the method a conventional steel was tested in Charpy tests as well as in the new tensile impact test.

Review of the literature regarding rodent experimental flap models reveals fundamental differences in applied surgical procedures. Although some authors isolate the flap from its wound bed, others do not. This study was planned to investigate to what extent the insertion of a silicone sheet affects physiological wound healing in experimental flap surgery. An extended epigastric adipocutaneous flap (6 × 10 cm) was raised in 16 male Lewis rats. In the control group (group C), flaps were immediately inset without any intervention. In the experimental group (group M), a silicone sheet barrier was placed between the flap and the wound bed. Mean flap survival area and flap perfusion were evaluated. Microvessel density was visualized by immunohistochemistry, and semiquantitative real-time polymerase chain reaction addressed differential gene expression. All animals were investigated on postoperative day 5. Flap survival area and flap perfusion were found to be similar. Immunohistochemistry, however, demonstrated a significantly increased number of CD31-positive small vessels in group C. The insertion of the silicone sheet barrier (group M) was accompanied by a significantly enhanced expression of proinflammatory genes and a suppression of proangiogenic genes. Our results show that although the silicone membrane has no influence on the surgical outcome in terms of flap survival and perfusion, it does lead to significant molecular alterations in pathways involved in physiological wound healing. These alterations are artificially induced by the foreign body material and conceal the true driving forces of the healing process. As the latter might include relevant therapeutic targets to ameliorate surgical results, we regard wound bed isolation as a dispensable procedure in the study of rodent flap models.

The practice of rural and remote medicine in Australia entails many challenges, including a broad casemix and the remoteness of specialist support. Many rural practitioners employ advanced procedural skills in anaesthetics, surgery, obstetrics and emergency medicine, but the use of these skills has been declining over the last 20 years. This study explored the perceptions of rural general practitioners (GPs) on the current and future situation of procedural medicine. The qualitative results of data from a mixed-method design are reported. Free-response survey comments and semistructured interview transcripts were analysed by a framework analysis for major themes. General practices in rural and remote Queensland. Rural GPs in Rural and Remote Metropolitan Classification 4-7 areas of Queensland. The perceptions of rural GPs on the current and future situation of rural procedural medicine. Major concerns from the survey focused on closure of facilities and downgrading of services, cost and time to keep up skills, increasing litigation issues and changing attitudes of the public. Interviews designed to draw out solutions to help rectify the perceived circumstances highlighted two major themes: 'synergy' between the support from medical teams and community in ensuring 'sustainability' of services. This article presents a model of rural procedural practice where synergy between staff, resources and support networks represents the optimal way to deliver a non-metropolitan procedural service. The findings serve to remind educators and policy-makers that future planning for sustainability of rural procedural services must be broad-based and comprehensive.

Surgeons in high-income countries increasingly are expressing interest in global surgery and participating in humanitarian missions. Knowledge of the surgical skills required to adequately respond to humanitarian emergencies is essential to prepare such surgeons and plan for interventions. A retrospective review of all surgical procedures performed at Médecins Sans Frontières Brussels facilities from June 2008 to December 2012 was performed. Individual data points included country of project; patient age and sex; and surgical indication and surgical procedure. Between June 2008 and December 2012, a total of 93,385 procedures were performed on 83,911 patients in 21 different countries. The most common surgical indication was for fetal-maternal pathologies, accounting for 25,548 of 65,373 (39.1%) of all cases. The most common procedure was a Cesarean delivery, accounting for a total of 24,182 or 25.9% of all procedures. Herniorrhaphies (9,873/93,385, 10.6%) and minor surgeries (11,332/93,385, 12.1%), including wound debridement, abscess drainage and circumcision, were also common. A basic skill set that includes the ability to provide surgical care for a wide variety of surgical morbidities is urgently needed to cope with the surgical need of humanitarian emergencies. This review of Médecins Sans Frontières's operative procedures provides valuable insight into the types of operations with which an aspiring volunteer surgeon should be familiar.

Large Woody Debris (LWD) are an integral component of the fluvial environment. They represent an environmental resource, but without doubt they represent also a risk factor for the amplification that could give to the destructive power of a flood event. While countless intervention in river channels have reintroduced wood in rivers with restoration and banks protection aims, during several flash flood events LWD have had a great part in catastrophic consequences, pointing out the urgency of an adequate risk assessment procedure. At present wood dynamics in rivers is not systematically considered within the procedures for the elaboration of hazard maps resulting in loss of prediction accuracy and underestimation of hazard impacts. The assessment inconsistency comes from the complexity of the question: several aspects in wood processes are not yet well known and the superposition of different physical phenomena results in great difficulty to predict critical scenarios. The presented research activity has been aimed to improve management skills for the assessment of the hydrologic risk associated to the presence of large woody debris in rivers, improving knowledge about LWD dynamic processes and proposing effective tools for monitoring and mapping river catchments vulnerability. Utilizing critical review of the published works, field surveys and experimental investigations LWD damaging potential has been analysed to support the identification of the exposed sites and the redaction of hazard maps, taking into account that a comprehensive procedure has to involve: a) Identification of the critical cross sections; b) Evaluation of wood availability in the river catchment; c) Prediction of hazard scenarios through the estimation of water discharge, wood recruitment and entrainment, wood transport and destination. Particularly, a survey sheets form for direct measurements has been implemented and tested in field to provide an investigation instruments for wood and river reach monitoring. The sheets have been settled down to answer to several information requests involved in all steps of a risk assessment procedure, and to provide useful indications for a better comprehension of the dynamics of wood in rivers. Based on a critical analysis of the current state of the art an improved theoretical mechanistic model of LWD entrainment has been proposed and tested with flume experiments, considering this feature a crucial aspect in wood dynamics. The entrainment condition is traditionally physically based on the stationary equilibrium of gravity, buoyancy, friction and hydrodynamic forces acting on the body partially submerged in a flow field. In this work no any force has been neglected a priori and an original interpretation of some aspects of the problem has been adduced taking cues from different disciplines The proposed approach is able to provide a threshold parameter, showing relative small experimental scatter, and to discriminate between entrainment modes (sliding, rolling, floating). The provided correlation, for each particular configuration of the debris (shape and orientation), establish the threshold value for the proposed entrainment criterion that allows determining, for a discharge with a certain recurrence interval, the probability of motion and the relative entrainment mode.

Cognitive load theory, focusing on limits of the working memory, is relevant to medical education; however, factors associated with cognitive load during procedural skills training are not well characterized. The authors sought to determine how features of learners, patients/tasks, settings, and supervisors were associated with three types of cognitive load among learners performing a specific procedure, colonoscopy, to identify implications for procedural teaching. Data were collected through an electronically administered survey sent to 1,061 U.S. gastroenterology fellows during the 2014-2015 academic year; 477 (45.0%) participated. Participants completed the survey immediately following a colonoscopy. Using multivariable linear regression analyses, the authors identified sets of features associated with intrinsic, extraneous, and germane loads. Features associated with intrinsic load included learners (prior experience and year in training negatively associated, fatigue positively associated) and patient/tasks (procedural complexity positively associated, better patient tolerance negatively associated). Features associated with extraneous load included learners (fatigue positively associated), setting (queue order positively associated), and supervisors (supervisor engagement and confidence negatively associated). Only one feature, supervisor engagement, was (positively) associated with germane load. These data support practical recommendations for teaching procedural skills through the lens of cognitive load theory. To optimize intrinsic load, level of experience and competence of learners should be balanced with procedural complexity; part-task approaches and scaffolding may be beneficial. To reduce extraneous load, teachers should remain engaged, and factors within the procedural setting that may interfere with learning should be minimized. To optimize germane load, teachers should remain engaged.

As new technology is developed and scientific evidence demonstrates strategies to improve the quality of care, it is essential that surgeons keep current with their skills. Rural surgeons need efficient and targeted continuing medical education that matches their broader scope of practice. Developing such a program begins with an assessment of the learning needs of the rural surgeon. The aim of this study was to assess the learning needs considered most important to surgeons practicing in rural areas. A needs assessment questionnaire was administered to surgeons practicing in rural areas. An additional gap analysis questionnaire was administered to registrants of a skills course for rural surgeons. Seventy-one needs assessment questionnaires were completed. The self-reported procedures most commonly performed included laparoscopic cholecystectomy (n = 44), hernia repair (n = 42), endoscopy (n = 43), breast surgery (n = 23), appendectomy (n = 20), and colon resection (n = 18). Respondents indicated that they would most like to learn more skills related to laparoscopic colon resection (n = 16), laparoscopic antireflux procedures (n = 6), laparoscopic common bile duct exploration/ERCP (n = 5), colonoscopy/advanced techniques and esophagogastroscopy (n = 4), and breast surgery (n = 4). Ultrasound, hand surgery, and leadership and communication were additional topics rated as useful by the respondents. Skills course participants indicated varying levels of experience and confidence with breast ultrasound, ultrasound for central line insertion, hand injury, and facial soft tissue injury. Our results demonstrated that surgeons practicing in rural areas have a strong interest in acquiring additional skills in a variety of general and subspecialty surgical procedures. The information obtained in this study may be used to guide curriculum development of further postgraduate skills courses targeted to rural surgeons. Copyright © 2013 American College of Surgeons.

Psychological intervention programs for reduction of injury in ballet dancers.

PubMed

Noh, Young-Eun; Morris, Tony; Andersen, Mark B

2007-01-01

The purpose of this study was to examine the effects of two psychological interventions designed to reduce injury among dancers by enhancing coping skills. Participants were 35 ballet dancers. They were assigned to three conditions: control (n = 12), autogenic training (n = 12), and a broad-based coping skills condition, including autogenic training, imagery, and self-talk (n = 11). The 12-week interventions were designed on the basis of results from previous studies. For the 12 weeks following the intervention, participants were asked to practice their respective interventions three times a week. During the 24-week period (12 weeks training plus 12 weeks practice), training staff at the dance academies recorded injuries on a record sheet each day. Participants wrote injury records by themselves for another 24 weeks. Multivariate analysis of variance (MANOVA) and univariate tests for each dependent variable showed that the broad-based coping skills condition enhanced coping skills, in particular, peaking under pressure, coping with adversity, having confidence and achievement motivation, and concentrating. Separate analyses of covariance (ANCOVA), one using preintervention injury frequency as the covariate and one using preintervention injury duration as the covariate, revealed that participants in the broad-based coping skills condition spent less time injured than participants in the control condition.

Assessing the surgical skills of trainees in the operating theatre: a prospective observational study of the methodology.

To compare user satisfaction and acceptability, reliability and validity of three different methods of assessing the surgical skills of trainees by direct observation in the operating theatre across a range of different surgical specialties and index procedures. A 2-year prospective, observational study in the operating theatres of three teaching hospitals in Sheffield. The assessment methods were procedure-based assessment (PBA), Objective Structured Assessment of Technical Skills (OSATS) and Non-technical Skills for Surgeons (NOTSS). The specialties were obstetrics and gynaecology (O&G) and upper gastrointestinal, colorectal, cardiac, vascular and orthopaedic surgery. Two to four typical index procedures were selected from each specialty. Surgical trainees were directly observed performing typical index procedures and assessed using a combination of two of the three methods (OSATS or PBA and NOTSS for O&G, PBA and NOTSS for the other specialties) by the consultant clinical supervisor for the case and the anaesthetist and/or scrub nurse, as well as one or more independent assessors from the research team. Information on user satisfaction and acceptability of each assessment method from both assessor and trainee perspectives was obtained from structured questionnaires. The reliability of each method was measured using generalisability theory. Aspects of validity included the internal structure of each tool and correlation between tools, construct validity, predictive validity, interprocedural differences, the effect of assessor designation and the effect of assessment on performance. Of the 558 patients who were consented, a total of 437 (78%) cases were included in the study: 51 consultant clinical supervisors, 56 anaesthetists, 39 nurses, 2 surgical care practitioners and 4 independent assessors provided 1635 assessments on 85 trainees undertaking the 437 cases. A total of 749 PBAs, 695 NOTSS and 191 OSATSs were performed. Non-O&G clinical supervisors and trainees provided mixed, but predominantly positive, responses about a range of applications of PBA. Most felt that PBA was important in surgical education, and would use it again in the future and did not feel that it added time to the operating list. The overall satisfaction of O&G clinical supervisors and trainees with OSATS was not as high, and a majority of those who used both preferred PBA. A majority of anaesthetists and nurses felt that NOTSS allowed them to rate interpersonal skills (communication, teamwork and leadership) more easily than cognitive skills (situation awareness and decision-making), that it had formative value and that it was a valuable adjunct to the assessment of technical skills. PBA demonstrated high reliability (G > 0.8 for only three assessor judgements on the same index procedure). OSATS had lower reliability (G > 0.8 for five assessor judgements on the same index procedure). Both were less reliable on a mix of procedures because of strong procedure-specific factors. A direct comparison of PBA between O&G and non-O&G cases showed a striking difference in reliability. Within O&G, a good level of reliability (G > 0.8) could not be obtained using a feasible number of assessments. Conversely, the reliability within non-O&G cases was exceptionally high, with only two assessor judgements being required. The reasons for this difference probably include the more summative purpose of assessment in O&G and the much higher proportion of O&G trainees in this study with training concerns (42% vs 4%). The reliability of NOTSS was lower than that for PBA. Reliability for the same procedure (G > 0.8) required six assessor judgements. However, as procedure-specific factors exerted a lesser influence on NOTSS, reliability on a mix of procedures could be achieved using only eight assessor judgements. NOTSS also demonstrated a valid internal structure. The strongest correlations between NOTSS and PBA or OSATS were in the 'decision-making' domain. PBA and NOTSS showed better construct validity than OSATS, the year of training and the number of recent index procedures performed being significant independent predictors of performance. There was little variation in scoring between different procedures or different designations of assessor. The results suggest that PBA is a reliable and acceptable method of assessing surgical skills, with good construct validity. Specialties that use OSATS may wish to consider changing the design or switching to PBA. Whatever workplace-based assessment method is used, the purpose, timing and frequency of assessment require detailed guidance. NOTSS is a promising tool for the assessment of non-technical skills, and surgical specialties may wish to consider its inclusion in their assessment framework. Further research is required into the use of health-care professionals other than consultant surgeons to assess trainees, the relationship between performance and experience, the educational impact of assessment and the additional value of video recording.

The build-up, configuration, and dynamical sensitivity of the Eurasian ice-sheet complex to Late Weichselian climatic and oceanic forcing

The Eurasian ice-sheet complex (EISC) was the third largest ice mass during the Last Glacial Maximum (LGM), after the Antarctic and North American ice sheets. Despite its global significance, a comprehensive account of its evolution from independent nucleation centres to its maximum extent is conspicuously lacking. Here, a first-order, thermomechanical model, robustly constrained by empirical evidence, is used to investigate the dynamics of the EISC throughout its build-up to its maximum configuration. The ice flow model is coupled to a reference climate and applied at 10 km spatial resolution across a domain that includes the three main spreading centres of the Celtic, Fennoscandian and Barents Sea ice sheets. The model is forced with the NGRIP palaeo-isotope curve from 37 ka BP onwards and model skill is assessed against collated flowsets, marginal moraines, exposure ages and relative sea-level history. The evolution of the EISC to its LGM configuration was complex and asynchronous; the western, maritime margins of the Fennoscandian and Celtic ice sheets responded rapidly and advanced across their continental shelves by 29 ka BP, yet the maximum aerial extent (5.48 × 106 km2) and volume (7.18 × 106 km3) of the ice complex was attained some 6 ka later at c. 22.7 ka BP. This maximum stand was short-lived as the North Sea and Atlantic margins were already in retreat whilst eastern margins were still advancing up until c. 20 ka BP. High rates of basal erosion are modelled beneath ice streams and outlet glaciers draining the Celtic and Fennoscandian ice sheets with extensive preservation elsewhere due to frozen subglacial conditions, including much of the Barents and Kara seas. Here, and elsewhere across the Norwegian shelf and North Sea, high pressure subglacial conditions would have promoted localised gas hydrate formation.

Understanding calving dynamics of Greenland outlet glaciers by comparing calving laws in a 3D ice sheet model

Mass loss from marine terminating glaciers along coastal Greenland is a significant contributor to global sea-level rise. Calving is one of the important processes that control the dynamics, and therefore the discharge, of these glaciers. As glacier termini are exposed to warmer ocean currents, ocean-induced melt at the calving front increases, which may lead to glacier retreat and ice flow acceleration. It is therefore important to accurately parameterize calving in ice sheet models in order to improve the projections of ice sheet change. Several calving laws have been proposed, but most of them have been applied only to a specific region and have not been tested on other glaciers, while some others have only been implemented in one-dimensional flowline or vertical flowband models. Here, we test and compare several calving laws recently proposed in the literature using a 3D ice sheet model. Namely: the height-above-buoyancy criterion (Vieli et al., 2002), the crevasse-depth calving law (Benn et al., 2007), the eigencalving law (Levermann et al., 2012) and von Mises tensile stress calving law (Morlighem et al., 2016). We test these calving laws on Zachariae Isstrøm (Northeast), Upernavik (Central West) and Helheim (East) glaciers of Greenland. We compare the modeled ice front evolution to the observed retreat from Landsat data, and assess which calving law has the best predictive skills for each glacier. Overall, von Mises tensile stress calving laws is more satisfactory than others for most regions. This study shows that calving dynamics needs to be 3D in ice sheet models to account for the complex geometry and narrow fjords along the coast of Greenland. Comparing calving laws in a 3D model makes it possible to find missing mechanisms in each criterion and to improve existing calving laws in numerical ice sheet models, which could reduce uncertainties in future sea level rise projections.

We present a prototype Virtual Ice Sheet Laboratory (VISL) geared to K-12 classrooms and the general public, with the goal of improving climate literacy, especially in regards to the crucial role of the polar ice sheets in Earth's climate and sea level. VISL will allow users to perform guided experiments using the Ice Sheet System Model (ISSM), a state-of-the-art ice flow model developed at NASA's Jet Propulsion Laboratory and UC Irvine that simulates the near-term evolution of the ice sheets on Greenland and Antarctica. VISL users will access ISSM via a graphical interface that can be launched from a web browser on a computer, tablet or smart phone. Users select climate conditions and run time by moving graphic sliders then watch how a given region evolves in time under those conditions. Lesson plans will include conceptual background, instructions for table top experiments related to the concepts addressed in a given lesson, and a guide for performing model experiments and interpreting their results. Activities with different degrees of complexity will aim for consistency with NGSS Physical Science criteria for different grade bands (K-2, 3-5, 6-8, and 9-12), although they will not be labeled as such to encourage a broad user base. Activities will emphasize the development of physical intuition and critical thinking skills, understanding conceptual and computational models, as well as observation recording, concept articulation, hypothesis formulation and testing, and mathematical analysis. At our present phase of development, we seek input from the greater science education and outreach communities regarding VISL's planned content, as well as additional features and topic areas that educators and students would find useful.

A realistic model for the instruction of basic dermatologic procedural skills was developed, while simultaneously increasing medical student exposure to the field of dermatology. The primary purpose of the authors' study was to evaluate the utilization of a fresh-tissue cadaver model (FTCM) as a method for the instruction of common dermatologic procedures. The authors' secondary aim was to assess students' perceived clinical skills and overall perception of the field of dermatology after the lab. Nineteen first- and second-year medical students were pre- and post-tested on their ability to perform punch and excisional biopsies on a fresh-tissue cadaver. Students were then surveyed on their experience. Assessment of the cognitive knowledge gain and technical skills revealed a statistically significant improvement in all categories (p < .001). An analysis of the survey demonstrated that 78.9% were more interested in selecting dermatology as a career and 63.2% of participants were more likely to refer their future patients to a Mohs surgeon. An FTCM is a viable method for the instruction and training of dermatologic procedures. In addition, the authors conclude that an FTCM provides realistic instruction for common dermatologic procedures and enhances medical students' early exposure and interest in the field of dermatology.

INtraoperative Video Enhanced Surgical procedure Training (INVEST) is a new training method designed to improve the transition from basic skills training in a skills lab to procedural training in the operating theater. Traditionally, the master-apprentice model (MAM) is used for procedural training in the operating theater, but this model lacks uniformity and efficiency at the beginning of the learning curve. This study was designed to investigate the effectiveness and efficiency of INVEST compared to MAM. Ten surgical residents with no laparoscopic experience were recruited for a laparoscopic cholecystectomy training curriculum either by the MAM or with INVEST. After a uniform course in basic laparoscopic skills, each trainee performed six cholecystectomies that were digitally recorded. For 14 steps of the procedure, an observer who was blinded for the type of training determined whether the step was performed entirely by the trainee (2 points), partially by the trainee (1 point), or by the supervisor (0 points). Time measurements revealed the total procedure time and the amount of effective procedure time during which the trainee acted as the operating surgeon. Results were compared between both groups. Trainees in the INVEST group were awarded statistically significant more points (115.8 vs. 70.2; p < 0.001) and performed more steps without the interference of the supervisor (46.6 vs. 18.8; p < 0.001). Total procedure time was not lengthened by INVEST, and the part performed by trainees was significantly larger (69.9 vs. 54.1 %; p = 0.004). INVEST enhances effectiveness and training efficiency for procedural training inside the operating theater without compromising operating theater time efficiency.

A needs assessment identified a gap in teaching and assessment of laparoscopic suturing (LS) skills. The purpose of this review is to identify assessment tools that were used to assess LS skills, to evaluate validity evidence available, and to provide guidance for selecting the right assessment tool for specific assessment conditions. Bibliographic databases were searched till April 2017. Full-text articles were included if they reported on assessment tools used in the operating room/simulation to (1) assess procedures that require LS or (2) specifically assess LS skills. Forty-two tools were identified, of which 26 were used for assessing LS skills specifically and 26 for procedures that require LS. Tools had the most evidence in internal structure and relationship to other variables, and least in consequences. Through identification and evaluation of assessment tools, the results of this review could be used as a guideline when implementing assessment tools into training programs.

The influence of intraoral exposure procedures on the physical characteristics of thermoplastic vacuum-formed retainers (VFRs) is still unclear. The effects of thermoforming and intraoral use on the molecular, chemical, morphological, and mechanical properties of thermoplastic VFRs were investigated. VFRs with a 0.8-mm-thick thermoplastic PETG sheet acquired from 48 patients were investigated with two aging procedures, including vacuum forming and intraoral exposure, for 2-week and 6-month. Eight evaluating sites for thermoplastic VFRs were assessed with seven analytical techniques. LM, SEM, and AFM microscopic findings showed that the surface characteristics increased with increasing in vivo exposure time (a four-fold increase) and varied depending on the sites evaluated (an occlusal surface). Raman and EDX spectroscopic findings showed that aging procedures led to a significant change in the molecular composition of VFRs, leading to a decrease in the composition rate of carbon (C) and the presence of silicon (Si), phosphorus (P), and calcium (Ca). Compressive strength and tensile tests showed that aging procedures led to a significant increase (P<0.01) in ultimate tensile strength, elastic modulus, the stored energy at a 6-mm deflection (u6 mm), and the compressed load at a 3-mm deflection (σ3 mm). Thermoforming led to a smoother surface and no crystallization of PETG sheets. Intraoral exposure accelerated changes in surface morphology, tensile strength, and elastic modulus of VFRs. This change was site-specific and enhanced with an increase in intraoral exposure time. Therefore, thermoforming and in vivo oral exposure procedures led to the molecular, morphological, and mechanical properties of thermoplastic VFRs. Copyright © 2015 Elsevier Ltd.

The purpose of this study is to determine the effects of simulation-based medical education (SBME) on the skills required to perform coronary angiography in the cardiac catheterization laboratory. Cardiovascular fellows commonly learn invasive procedures on patients. Because this approach is not standardized, it can result in inconsistent skill acquisition through exclusion of concepts and skills. Also, the learning curve varies between trainees yielding variability in skill acquisition. Therefore, coronary angiography skills are an excellent target for SBME in an environment in which direct patient care is not jeopardized. From January 2013 to June 2013, 14 cardiovascular fellows entering the cardiac catheterization laboratory at a tertiary care teaching hospital were tested on an endovascular simulator to assess baseline skills. All fellows subsequently underwent didactic teaching and preceptor-lead training on the endovascular simulator. Topics included basic catheterization skills and a review of catheterization laboratory systems. Following training, all fellows underwent a post-training assessment on the endovascular simulator. Paired t tests were used to compare items on the skills checklist and simulator defined variables. Cardiovascular fellows scored significantly higher on a diagnostic coronary angiography skills checklist following SBME using an endovascular simulator. The mean pretest score was 66.6% (SD = 9.7%) compared to 86.0% (SD = 6.3%) following simulator training (P < 0.001). Additional findings include significant reduction in procedure time and use of cine-fluoroscopy at posttest. SBME significantly improved cardiovascular fellows' performance of simulated coronary angiography skills. Standardized simulation-based education is a valuable adjunct to traditional clinical education for cardiovascular fellows. © 2015 Wiley Periodicals, Inc.

A novel large wave flume experiment was conducted on a fixed, barred beach with a sediment pit on the sandbar, allowing for the isolation of small-scale bed response to large-scale forcing. Concurrent measurements of instantaneous sheet layer sediment concentration profiles and near-bed velocity profiles were obtained on a sandbar for the first time. Two sediment distributions were used with median grain diameters, d50, of 0.17 and 0.27 mm. Sheet flow occurred primarily under wave crests, where sheet thickness increased with increasing wave height. A proportionality constant, Λ, was used to relate maximum Shields parameter to maximum sheet thickness (normalized by d50), with bed shear stress computed using the quadratic drag law. An enhanced sheet layer thickness was apparent for the smaller sediment experiments (Λ = 18.7), when directly compared to closed-conduit oscillatory flow tunnel data (Λ = 10.6). However, Λ varied significantly (5 < Λ < 31) depending on the procedure used to estimate grain roughness, ks, and wave friction factor, fw. Three models for ks were compared (keeping the model for fw fixed): constant ks = 2.5d50, and two expressions dependent on flow intensity, derived from steady and oscillatory sheet flow experiments. Values of ks/d50 varied by two orders of magnitude and exhibited an inverse relationship with Λ, where Λ ˜ 30 for ks/d50 of O(1) while Λ ˜ 5 for ks/d50 of O(100). Two expressions for fw were also tested (with the steady flow-based model for ks), yielding a difference of 69% (Λ ˜ 13 versus Λ ˜ 22).

The interplay of tectonics and climate is recorded in the sedimentary strata within Victoria Land Basin, McMurdo Sound, Antarctica. Patterns of Cenozoic sedimentation are documented from interpretation of seismic reflection profiles calibrated by drillhole data in McMurdo Sound, and these patterns provide enhanced constraints on the evolution of the coupled Transantarctic Mountains-West Antarctic Rift System and on ice sheet advance/retreat through multiple climate cycles. The research focuses on shifts from warm based to cold based ice sheets through the variable climate and ice sheet conditions that characterized the early to middle Miocene. The study seeks to test the view that cold based ice sheets in arid, polar deserts minimally erode the landscape by calculating sediment volumes for critical climatic intervals. Revised seismic mapping through McMurdo Sound has been completed, utilizing the seismic stratigraphic framework first established by Fielding et al. (2006) and new reflectors marking unconformities identified from the AND-2A core (Levy et al., 2016). Reflector age constraints are derived by tying surfaces to the Cape Roberts Project, CIROS-1, and AND-2A drillholes. Seismic facies coupled with AND-2A core provenance information provides insight into depositional mechanisms and ice sheet behavior. Seismic facies transitions occur across the major unconformity surfaces in the AND-2A core. Sediment volume calculations for subareas within McMurdo Sound where reflectors are most continuous indicate substantial decreases in preserved sediment volume between the Oligocene and Early Miocene sequences, and between the early and mid-Miocene sequences. Sediment volumes, used in combination with an ice sheet model in a backstacking procedure, provide constraints on landscape modification and further understanding of how landscapes erode under warm and cold based ice sheet regimes.

Coping with the issue of water scarcity and growing competition for water among different sectors requires proper water management strategies and decision processes. A pre-requisite is a clear understanding of the basin hydrological processes, manageable and unmanageable water flows, the interaction with land use and opportunities to mitigate the negative effects and increase the benefits of water depletion on society. Currently, water professionals do not have a common framework that links hydrological flows to user groups of water and their benefits. The absence of a standard hydrological and water management summary is causing confusion and wrong decisions. The non-availability of water flow data is one of the underpinning reasons for not having operational water accounting systems for river basins in place. In this paper we introduce Water Accounting Plus (WA+), which is a new framework designed to provide explicit spatial information on water depletion and net withdrawal processes in complex river basins. The influence of land use on the water cycle is described explicitly by defining land use groups with common characteristics. Analogous to financial accounting, WA+ presents four sheets including (i) a resource base sheet, (ii) a consumption sheet, (iii) a productivity sheet, and (iv) a withdrawal sheet. Every sheet encompasses a set of indicators that summarize the overall water resources situation. The impact of external (e.g. climate change) and internal influences (e.g. infrastructure building) can be estimated by studying the changes in these WA+ indicators. Satellite measurements can be used for 3 out of the 4 sheets, but is not a precondition for implementing WA+ framework. Data from hydrological models and water allocation models can also be used as inputs to WA+.
