Muscle hernia (MH) is a focal protrusion of muscle into the overlying subcutaneous tissue through an acquired or congenital facial defect. Herniation in the thigh muscles is not common and there are limited reports evaluating this pathology using ultrasonography (US). A 28-year-old amateur football player presented with a palpable mass on the anterior aspect of his right thigh. Sonographic examination demonstrated a MH through a fascial defect, which is called mushroom appearance. Based on the clinical and sonographic findings, the diagnosis of a MH in the rectus femoris muscle was established. Today, there is no doubt anymore on the role of musculoskeletal US in the field of sports injuries. Therefore, with its various advantages (non-invasive, practical and convenient, inexpensive, etc.), US is the key imaging method in the diagnosis of MHs. 相似文献

IntroductionFollowing a pandemic, laboratory medicine is vulnerable to laboratory errors due to the stressful and high workloads. We aimed to examine how laboratory errors may arise from factors, e.g., flexible working order, staff displacement, changes in the number of tests, and samples will reflect on the total test process (TTP) during the pandemic period.Materials and methodsIn 12 months, 6 months before and during the pandemic, laboratory errors were assessed via quality indicators (QIs) related to TTP phases. QIs were grouped as pre-, intra- and postanalytical. The results of QIs were expressed in defect percentages and sigma, evaluated with 3 levels of performance quality: 25th, 50th and 75th percentile values.ResultsWhen the pre- and during pandemic periods were compared, the sigma value of the samples not received was significantly lower in pre-pandemic group than during pandemic group (4.7σ vs. 5.4σ, P = 0.003). The sigma values of samples transported inappropriately and haemolysed samples were significantly higher in pre-pandemic period than during pandemic (5.0σ vs. 4.9σ, 4.3σ vs. 4.1σ; P = 0.046 and P = 0.044, respectively). Sigma value of tests with inappropriate IQC performances was lower during pandemic compared to the pre-pandemic period (3.3σ vs. 3.2σ, P = 0.081). Sigma value of the reports delivered outside the specified time was higher during pandemic than pre-pandemic period (3.0σ vs. 3.1σ, P = 0.030).ConclusionIn all TTP phases, some quality indicators improved while others regressed during the pandemic period. It was observed that preanalytical phase was affected more by the pandemic. 相似文献

ABSTRACTDistance education (DE) is a constantly evolving and advancing field, and as such, its intellectual network and dynamics need to be investigated and explored. In this regard, this study reviewed a total of 1685 articles and 51,940 references through social network analysis for a bibliometric examination of the DE field. The findings indicate that DE is an interdisciplinary field and part of mainstream education. The progressive knowledge domain analysis revealed that the intellectual roots of DE stem from generic social learning theories, after which DE-related theories began to emerge following the foundation of open universities. The research concludes that there was a paradigm shift that resulted from developments in online networked technologies in the 2000s, at which time DE started to gradually evolve into sixth generation ubiquitous DE. 相似文献

This study examined the effectiveness of the First Step to Success (FSS) early intervention program for preventing antisocial behavior in Turkey. Participants included 24 students, their teachers and parents from four K–8 elementary schools. The experimental group included 12 targeted students (four kindergarten, four first-grade and four second-grade students) who received the intervention. Both quantitative and qualitative methods were carried out by using a pre-posttest experimental design. Results indicated that there were significant decreases in problem behaviors and significant increases in social skills and academic competence of targeted students. In addition, teachers and parents reported significant positive changes in problem behaviors and social skills of their children. Most teachers and parents were highly satisfied with the program. Limitations of the study and directions for future research are discussed. 相似文献

This study focused on the development of a two-tier multiple-choice diagnostic instrument, which was designed and then progressively modified, and implemented to assess students' understanding of solution chemistry concepts. The results of the study are derived from the responses of 756 Grade 11 students (age 16–17) from 14 different high schools who participated in the study. The final version of the instrument included a total of 13 items that addressed the six aspects of solution chemistry, and students' understandings in the test were challenged in multiple contexts with multiple modes and levels of representation. Cronbach alpha reliability coefficients for the content tier and both tiers of the test were found to be 0.697 and 0.748, respectively. Results indicated that a substantial number of students held an inadequate understanding of solution chemistry concepts. In addition, 21 alternative conceptions observed in more than 10% of the students were reported, along with discussion on possible sources of such conceptions. 相似文献

Maritime services form an integral part of what regulatory agencies requires for the safe navigation and operation of vessels. Therefore, the maritime industry’s compliance with governmental regulations and international protocols has been essential for maritime safety management. As a basis to this aspect, the preparation of maritime students as the forthcoming maritime officers in the future has been a crucial point by the maritime educators in terms of maritime safety. Although English was adopted as the official language of the maritime industries by the International Convention on Standards of Training, Certification and Watchkeeping (STCW Convention) in 1978, many difficulties remain in the teaching and assessing of Maritime English at maritime schools. Some research has examined these difficulties; however, no successful models for improving. Maritime English have been adopted Parallel to the teaching and assessing problems, there have also been many difficulties in reaching a training and testing proficiency in English communication that meets the international standards of the STCW requirements in the maritime industry. This paper concentrates upon the difficulties of teaching and assessing the outcomes of the teaching of Maritime Transportation English at the member schools of the International Association of Maritime Universities (IAMU) from all over the world. As a first step in the methodology of this study, a survey of techniques used at member schools of the IAMU is conducted to solve some difficulties in assessing the teaching of Maritime English. Then a positioning model is developed to identify and measure the positions of the IAMU member schools in comparison to one another by using a multidimensional scaling technique to analyse the multivariate data received through questionnaires. This information provides the foundation upon which the model of this research is built. Consequently, some strategies based upon the results of the analysis are developed to reduce the problems and difficulties in this context. 相似文献

Social networks have become popular communication and interaction environments recently. As digital environments, so as ecosystems, they have potential in terms of networked learning as they fulfill some roles such as mediating an environment for digital identity formation and providing social and emotional presence. Based on this phenomenon, the importance of identity formation as a sociological and psychological process was explained throughout this study. Following that, social networks as digital social ecosystems and learning environments in which self-actualization, self-presentation, and self-disclosure of the individuals were discussed and their necessity as well as their potential for social and emotional presence was explained to better understand social networks. Besides, social networks and “Facebook” as a case were examined. Within this perspective, the purpose of this study was to explore online social networks with an emphasis on learning; to put forward its educational premises; and to analyze digital identity formation, social presence, and emotional presence in social networks. 相似文献
