Assessment Approach

Pilots also experience spatial disorientation (SD) when flying. One factor contributing to this issue is the lack of a validated procedure for detecting Type I (unrecognized) SD. Most of the current literature focuses on recognized SD evaluation methods, but there are few reports that concentrate on unrecognized SD evaluation methods. We go through some of the issues with SD and compare the various SD assessment approaches. We report on the benefits and drawbacks of the quantitative questionnaire assessment process and the behavior evaluation method in these books. We suggest a tool to diagnose unrecognized SD based on these analyses, which improves SD estimation in many ways. Centered on the subjective report and the core of strain, we establish a new approach to studying unrecognized SD (CoP). This latest approach compensates for the lack of unrecognized SD identification. We will help the pilots appreciate their emotions and physical adjustments as they are subjected to unrecognized SD by using the latest appraisal process. This assessment approach is hoped to provide good encouragement for unrecognized SD countermeasures and profoundly overcome the serious flight injuries induced by unrecognized SD.

The Impact

Background: The relationship between pitch volume and injury is well-represented within baseball literature. However, the impact of softball pitch volume on injury epidemiology is limited. Hypothesis: The purpose was to determine if increased pitch volumes in high school–aged softball pitchers are related to increased rates of subjectively reported pain/injury. We hypothesized that pitchers with increased volumes would have higher pain/injury rates. Study Design: Cross-sectional study. Level of Evidence: Level 4. Methods: A total of 28 female softball pitchers (aged 14-18 years) completed an online survey of questions pertaining to pitching history, pitch volume, and subjective report of pain or injury in the back, shoulder, and elbow. An independent-samples t test was used to (1) compare pitch volumes in those who reported pain in individual body regions (shoulder, elbow, back) compared with those who did not; (2) compare pitch volumes in those who reported pain in 0 or 1 of the regions of interest compared with 2 or 3 regions; and (3) compare the reported percentage of the past year that players reported playing through pain in players who averaged >85 compared with <85 pitches per game. Chi-square analysis was used to compare those who pitched either >85 or <85 pitches per game with regard to frequency of shoulder pain, elbow pain, back pain, seeking of medical attention, and actual injury diagnosis. Type I error was set at α = 0.05. Results: Weekly and yearly pitch counts were higher in those reporting pain or injury (YES) than those who did not (NO) in the shoulder (pitches per week: NO = 219 ± 35; YES = 429 ± 101; P = 0.027) (pitches per year: NO = 8876 ± 946; YES = 19,195 ± 4944; P = 0.022) and back (pitches per week: NO = 188 ± 16; YES = 426 ± 90; P = 0.014) (pitches per year: NO = 8334 ± 793; YES = 18,252 ± 4340; P = 0.027). Similar results were observed for those with pain or injury reported in 2 or 3 regions compared with 0 or 1 regions (pitches per week: NO = 220 ± 38; YES = 414 ± 95; P = 0.039) (pitches per year: NO = 8765 ± 1010; YES = 18,661 ± 4623; P = 0.028). Those reporting shoulder pain or injury also reported higher pitch counts per game (NO = 71.4 ± 5.2; YES = 83 ± 4; P = 0.049), and those reporting back pain also reported playing more games per week (NO = 2.7 ± 0.2; YES = 5.2 ± 1.1; P = 0.034). Those with pitch counts of >85/game were more than twice as likely to see a physician regarding pain/injury ( P = 0.027) and reported playing through pain a higher percentage of the year (>85, 49.3% ± 10%; <85, 25.2% ± 6%; P < 0.05). Conclusion: High pitching volumes commonly prevalent in high school–aged softball pitchers may be associated with increased pain/injury and appear related to cumulative volume. Clinical Relevance: This study provides recommendations for cumulative pitch volume guidelines in softball pitchers.

Fixture Configuration

A new FEA based design approach of optimal robust fixture configuration is proposed in this paper, which employs a surrogate model through computer experiment to significantly reduce the intensive computing effort involving numerous FEA system response evaluations. The effects of the fixture variability to the workpiece performance variability are assessed through an efficient robustness evaluation method, First Order Reliability Method (FORM), based on the surrogate computer model. Not restricted to primary datum surface, this new approach enables simultaneous determination of robust locator/clamp locations and clamping forces for a deformable workpiece and thus captures interaction between locating and clamping. The effectiveness of this approach is illustrated though an application example. The results of robustness analysis reveal new information and suggest that the optimal solution resulted from deterministic optimization may not be the best solution when the design is subjected to variability.

Insulin Gene Expression

Background: The discovery and use of CRISPR/Cas9 technology have enabled researchers throughout the globe to continuously edit genomes for the benefit of science and medicine. Diabetes type I is one field of medicine where CRISPR/Cas9 has a strong potential for cell therapy development. The long-lasting paucity of healthy cells for clinical transplantation into diabetic patients has led to the search of new methods for producing β-cells from other human cell types. Embryonic stem cells are being studied worldwide as one most promising solution of this need. Aim: The aim of the study is to to check the feasibility of modulating human insulin transcription using CRISPR/Cas9-based synthetic transcription regulation factors. Results: A new approach for creating potential therapeutic donor cells with enhanced and suppressed insulin production based on one of the latest achievements of human genome editing was developed. Both synthetic transcription activator (VP64) and transcription repressor (KRAB) proteins were shown to function adequately well as a part of the whole CRISPR/Cas9-based system. We claim that our results have a lot to offer and can bring light to many studies where numerous labs are struggling on to treat this disease.

Assessment Approach

Background: In an acute field-side setting, it is often challenging to differentiate benign sports-related concussion (SRC) from potential, more sinister, intracranial pathology. Moreover, recovery in the ensuing days and weeks is often complex as the resolution of classical signs and symptoms does not always follow a standard pattern. Aim: To highlight the value of a structured and repeated thorough clinical assessment approach toward SRC, particularly as atypical and unexpected sequences in patient recovery patterns may require further specialist referral and intervention. Findings: A football goalkeeper sustained a concussion in which symptoms failed to resolve as expected. Deterioration in his clinical condition led to an eventual diagnosis of Chiari malformation (type I), which required surgical intervention.Implications: Non-typical recovery patterns of concussion may be indicative of increased severity when considered retrospectively. However, clinicians should not discount the possibility of underlying conditions. Keywords: concussion, soccer, sports-related head injury

For the problems of few current defogging effect evaluation methods and limited evaluation methods, it proposes an image clarity effect evaluation method: the method combined with relative contrast and edge similarity. This is because: the contrast degree of fog image and non-fog image is obviously different. While improving image contrast degree, it should also try to make the edge structure of recovery image and reduced image consistent to prevent the recovery image from distorting. The experiment proves that this method can effectively evaluate the clarity effect of each algorithm, and the evaluation result and the subjective feelings of the human eyes are consistent. Compared with the existing evaluation methods, it obtains overall evaluation conclusion and also has a good practicability and reliability.

The existing evaluation methods have the problem of imperfect teaching effect evaluation model, which leads to the low reliability of the evaluation index. This paper designs a corpus based quantitative analysis method for teaching effect evaluation of Electronic Engineering English. Based on the mathematical principle of radial basis function, this paper uses corpus to analyze the distribution characteristics of Electronic Engineering English courses quantitatively, and uses association rules algorithm to build an English teaching effect evaluation model to comprehensively judge the importance of each factor. Experimental results: the average reliability of the two existing evaluation methods is 1.0751 and 0.5455 respectively, and the average reliability of the evaluation method is 0.7983, which shows that the reliability of the evaluation method is closer to the standard value of 0.8, which proves that the evaluation method of Electronic Engineering English teaching effect integrated with quantitative analysis of corpus has better practical application performance good.

ABSTRACT Contrast analysis has become prevalent in experimental accounting research since Buckless and Ravenscroft (1990) introduced it to the accounting literature over 25 years ago. Since its initial introduction, the scope of contrast testing has expanded, yet guidance as to the most appropriate methods of specifying, conducting, interpreting, and exhibiting these tests has not. We survey the use of contrast analysis in the recent literature and propose a three-part testing approach that provides a more comprehensive picture of contrast results. Our approach considers three pieces of complementary evidence: the visual evaluation of fit, traditional significance testing, and quantitative evaluation of the contrast variance residual. Our measure of the contrast variance residual, q2, is proposed for the first time in this work. After proposing our approach, we walk through six common contrast testing scenarios where current practices may fall short and our approach may guide researchers. We extend Buckless and Ravenscroft (1990) and contribute to the accounting research methods literature by documenting current contrast analysis practices that result in elevated Type I error and by proposing a potential solution to mitigate these concerns.
