Opis:
A short survey is reported on the advantageous and disadvantageous properties of soft magnetic glassy tapes to build stator and rotor elements for the increase of motor efficiency. The relative high saturation magnetization and the relative permeability of these alloy groups seem to be promising in this application field. On the other hand, the sample thickness (30 μm) displays limitations in terms of a filling factor. High hardness of tapes hinders the effectivity of mechanical shaping. Laser cutting can be successful as shaping method, presuming that the extension (thickness) of heat affected zone (HAZ) can be successfully reduced below 50μm, avoiding the brittleness evolution.

Opis:
Cheerleading is a new sport, practiced in 110 nations; since 2016 enjoys provisional Olympic status. Its leaders claim that it is a “happy” sport, but research on its psychological effects is lacking. In this field-study we examined core-affect, positive-affect, and negative-affect in 65 cheerleaders before, during, after, and one-hour after a cheerleading training. Core-affect was more positive during and immediately after training, but it tapered off one hour following the training when feeling states were still more positive than at baseline. Negative-affect declined linearly from baseline to one-hour following training when it became significantly lower than its previous values. Positive-affect showed quadratic dynamics, in parallel with arousal, being higher during and immediately after training than during baseline, or one-hour after training. These results demonstrate for the first time that cheerleading is a “happy” sport, which apart from the skill-development also yields positive psychological emotions both during and after training.

Opis:
Recent studies suggest that students fail to meet the international guidelines for physical activity. Therefore, an increased number of physical activity interventions attempt to change this trend. The current paper reviews the intervention studies which were based on the Self-Determination Theory (SDT). Three databases (PsycINFO, Medline, and SPORTDiscus) were scrutinized in the current review, which yielded 437 potential articles. Employing the recommended selection based on the population, intervention, comparators, and outcome (PICO), 14 articles could be included in the narrative analysis. The results showed that interventions based on the SDT were very heterogeneously operationalized in these studies. Despite different interventions, the results suggest that SDT-based interventions have the potential to increase students' physical activity through both, autonomy and supportive environment. Teachers' professional development in implementing SDT-based physical activity interventions for students is highly recommended.

Opis:
Emotional intelligence (EQ) was linked to sport participation. We report two studies in which we tested the link between exercise volume, defined as weekly hours of exercise, and EQ. Volunteers (n = 64 and n = 84) completed the Wong and Law Emotional Intelligence Scale. In Study I, significant correlations between exercise volume and use- and regulation-of-emotions prompted us to use a posteriori grouping into high- and low exercise-volume groups. The former exhibited better use-of-emotions than the latter (p = .007, d = .87). In Study II, using a priori grouping, we replicated the finding from Study I (p = .001, d = .78), and the groups also differed in “self-emotions appraisal” (p = .05, d = .44) and total EQ (p = .017, d = .54). Since the items measuring the use-of-emotions involve motivational aspects of the EQ, we posit that this dimension is “naturally” linked to exercise volume. Our findings also suggest that self-emotions appraisal and the overall EQ are linked to greater volumes of exercise. These results should provide an incentive for longitudinal studies in this area.

Opis:
ObjectivesThe aim was to compare the prevalence of acute infection and seropositivity of SARS-CoV-2 among healthcare workers (HCWs) and medical students.Material and MethodsA high-volume, single-center analysis was conducted in the period of July 1‒August 1, 2020, at the Semmelweis University. Naso- and oropharyngeal samples were collected for polymerase chain reaction (PCR), and blood samples for anti-SARS-CoV-2 IgG. A questionnaire was also administered about the infection symptoms and the obtained results were assessed by profession and site of care delivery.ResultsFrom the total cohort (N = 7948), 4478 (56%) and 3470 (44%) were health professionals and medical students, respectively. They were mainly female (67%), and the mean age of HCWs and students was 40 and 25 years, respectively. By profession, physicians (1.5%) and other HCWs (1.8%) showed a comparable SARS-CoV-2 exposure. International students had the highest (2.1%), whereas Hungarian students had the lowest (0.6%) prevalence of seropositivity. The highest prevalence was detected among the staff of COVID-19 wards (12.1%). By PCR, medical students showed the lowest occurrence of active infection with a prevalence of 0.17%, while physicians and other HCWs had a higher prevalence (1.46% and 1.71%, respectively). By site of care delivery, positive test results were the most frequent at COVID-19 wards (3.8%).ConclusionsPhysicians and other HCWs showed comparable SARS-CoV-2 seropositivity prevalence, approximately twice as high as in the general population of Budapest. Hungarian students had lower prevalence of seropositivity than this reference. High prevalence among international students suggests that they had imported the infection. The very high prevalence of documented exposure among staff members at COVID-19 wards urges for improving the safety measures.
