Fatigue and Physical Activity in People after COVID-19 in Poland

Objectives: The purpose of this research was to look at the amount of fatigue and physical activity (PA) in individuals after COVID-19 in Poland and the correlation between fatigue and PA. Methods: The online research was carried out among adult Polish residents (122 women and 82 men) who had tested positive for SARS-CoV-2 during the previous year. The level of fatigue was measured using the Modified Fatigue Impact Scale (MFIS). The PA level was assessed using the International Physical Activity Questionnaire (IPAQ). Results: A total of 46.6% of the subjects had been ill with COVID-19 for more than 6 months before the time of the survey response. The MFIS total measure is 77 of the maximum score, and the median is 17. A total of 26% of respondents reported low activity, while 41% of respondents reported high activity. A statistically significant negative relationship was found between PA level and total fatigue score. The best scores for fatigue and PA were obtained by the subjects with mild COVID-19. The time since diagnosis (as opposed to older age and female sex) was not clearly associated with most measures. Conclusions: PA may play an important role in regulating the severity of fatigue; it should be increased, especially in patients after COVID. Further studies are also needed to investigate the mechanism of differences in fatigue and PA.
Ergonomic study for comfort operating the pedals of the agricultural tractors

Aging and feminization of farming population are a major burden on current agricultural sector, and some measures are demanding to adjust this trend. The agricultural mechanization has relieved farmers of most of the hard physical labor, but still work environments are poor, and there are a lot of harmful factors affect- ing human health. Therefore, improvement of safety and comfort in agricultural machinery is needed. In case of the most commonly used domestic agricultural machinery, agricultural tractors, operation device loca- tion and operating force are regulated by international rules such as ISO 4253, but the rule is not sufficient for domestic operators, since it was not developed for operator's comfort and was drawn out based on the westerners. In this study, we developed a technique that evaluates the conformability of tractor driving operation device for all Korean farmers including senior and women farmers. We also established evaluation equip- ments and inspection method of tractor operation conformability to promote dissemination of tractors that suit for Korean farmers' physique. In the future, the result allows tractor manufacturers to propose design guidelines for proper location and operating force of tractor operating device. It also allows domestic agri- culture manufacturers to develop agricultural machinery that considered the conformability of farmers from the design stage.
Kinematics and wake of freely falling cylinders at moderate Reynolds numbers

We investigated experimentally the motion of elongated finite-length cylinders (length $L$ , diameter $d$ ) freely falling under the effect of buoyancy in a low-viscosity fluid otherwise at rest. For cylinders with densities $\unicode[STIX]{x1D70C}_{c}$ close to the density $\unicode[STIX]{x1D70C}_{f}$ of the fluid ( $\overline{\unicode[STIX]{x1D70C}}=\unicode[STIX]{x1D70C}_{c}/\unicode[STIX]{x1D70C}_{f}\simeq 1.16$ ), we explored the effect of the body volume by varying the Archimedes number $Ar$ (based on the body equivalent diameter) between 200 and 1100, as well as the effect of their length-to-diameter ratios $L/d$ ranging from 2 to 20. A shadowgraphy technique involving two cameras mounted on a travelling cart was used to track the cylinders along their fall over a distance longer than $30L$ . A dedicated image processing algorithm was further implemented to properly reconstruct the position and orientation of the cylinders in the three-dimensional space. In the range of parameters explored, we identified three main types of paths, matching regimes known to exist for three-dimensional bodies (short-length cylinders, disks and spheres). Two of these are stationary, namely, the rectilinear motion and the large-amplitude oscillatory motion (also referred to as fluttering or zigzag motion), and their characterization is the focus of the present paper. Furthermore, in the transitional region between these two regimes, we observed irregular low-amplitude oscillatory motions, that may be assimilated to the A-regimes or quasi-vertical regimes of the literature. Flow visualization using dye released from the bodies uncovered the existence of different types of vortex shedding in the wake of the cylinders, according to the style of path. The detailed analysis of the body kinematics in the fluttering regime brought to light a series of remarkable properties. In particular, when normalized with the characteristic velocity scale $u_{0}=\sqrt{(\overline{\unicode[STIX]{x1D70C}}-1)gd}$ and the characteristic length scale $l_{0}=\sqrt{dL}$ , the mean vertical velocity $\overline{u_{Z}}$ and the frequency $f$ of the oscillations become almost independent of $L/d$ and $Ar$ . The use of the length scale $l_{0}$ and of the gravitational velocity scale to build the Strouhal number $St^{\ast }=fl_{0}/u_{0}$ allowed us to generalize to short ( $0.1\leqslant L/d\leqslant 0.5$ ) and elongated cylinders ( $2\leqslant L/d\leqslant 12$ ), the result $St^{\ast }\simeq 0.1$ . An interpretation of $l_{0}$ as a characteristic length scale associated with the oscillatory recirculation thickness generated near the body ends is proposed. In addition, the rotation rate of the cylinders scales with $u_{0}/L$ , for all $L/d$ and $Ar$ investigated. Furthermore, the phase difference between the oscillations of the velocity component $u$ along the cylinder axis and of the inclination angle $\unicode[STIX]{x1D703}$ of the cylinder is approximately constant, whatever the elongation ratio $L/d$ and the Archimedes number $Ar$ .
Evaporation estimation using a floating pan

Almost all regions in the United States must accurately estimate evaporation to have effective water management programs. The purpose of this study is to develop a better method for measuring evaporation. Lake evaporation along with meteorological data are measured directly from a floating pan. The floating pan is specifically designed to account for one of the most sensitive parameters of evaporation, the water surface temperature. However, other factors such as air movement, solar radiation, stability, heat transfer, wave action, water level range, and site location were also taken into consideration while designing the floating pan system. The evaporation measured from the floating pan is compared to the two aerodynamic methods. Overall, the evaporation estimate using the Sill (1983) method is in close agreement to the evaporation data from the floating pan. The evaporation estimate for the months of September and October, 2006 from the two aerodynamic methods are compared to the data obtained from a land based pan. Both methods provide a lower estimate of evaporation compared to the SCDNR land based pan data. It is recommended that a water level sensor that is not influenced by temperature changes be used. The design of the floating pan allowed for the lake’s water surface temperature to be similar to that of the floating pan’s water surface temperature, which is one of the major components in evaporation prediction.
Selected miRNA and Psoriasis—Cardiovascular Disease (CVD)—Overweight/Obesity Network—A Pilot Study

Psoriasis is nowadays recognized as a multifactorial systemic disease with complex and not fully understood pathogenesis. In psoriatic patients, the increased cardiovascular disease (CVD) risk and frequent comorbidities like obesity are observed. The aim of this study was to investigate differences in miRNA (miR-22-3p, miR-133a-3p, miR-146a-5p, miR-369-3p, and Let-7b-5p) involved in CVD risk among psoriatic patients with overweight/obesity and with normal weight. The study comprised 28 male psoriatic patients and 16 male healthy controls. miRNA isolated from peripheral blood mononuclear cells was reverse-transcribed and RT-qPCR was performed. We have found decreased levels of miR-22, miR-133a, miR-146a, and miR-369 among the psoriatic patients. There was a statistically significant difference in miR-22 and miR-146a levels between psoriatic patients with overweight/obesity and with normal weight. There were positive correlations between miR-22 and miR-146a levels and psoriatic arthritis (PsA) in psoriatic patients with normal weight and between the miR-133a level and PsA in the overweight/obese patients. The decreased levels of selected miRNA are consistent with the levels observed in CVD indicating their impact on the CVD risk in psoriatic patients. miR-22 and miR-146 may be recognized as one of the contributing factors in the obesity-CVD-psoriasis network.
Let Us Know Transfusion Triggers for Prophylactic Use of Platelet Concentrate—Analysis of Compliance with Recent Transfusion Guidelines in a Large Academic Medical Center

Platelet concentrate (PC) is a blood component that is used to prevent or manage bleeding associated with thrombocytopenia or impaired platelet function. The aim of our study was to assess the compliance of ordering physicians with the most recent PC transfusion guidelines in our academic medical center. All PC transfusions performed between January 2019 and December 2022 were analyzed. The appropriateness of PC transfusions was assessed based on the most recent PC transfusion guidelines. During 2019–2022, there were 362 (0.2%) PC recipients out of 161,762 hospitalized patients. There were 971 PCs transfused during the analyzed period. Inappropriate transfusions accounted for 53.3% of cases, and most of them were given prophylactically (80.2%). Compliance with platelet transfusion guidelines varied among departments. The overall percentage of inappropriately transfused PC ranged from 50.7% to 60.8% in successive years. Educational activities should target clinicians performing procedures associated with high rates of inappropriate PC transfusions. Implementing clinical decision support systems can help reduce unnecessary PC transfusions and associated costs. The majority of inappropriate PC transfusions in our medical center were given as prophylaxis against bleeding. Prescribers should be educated about evidence-based transfusion triggers for the prophylactic use of PC in various clinical scenarios.
Swirl Characteristics of Vortex Valve Variable-Thrust Solid Rocket Motor

In accordance with the flow characteristics of vortex valve variable-thrust solid rocket motors, a cold flow experimental system based on Particle Image Velocimetry was established. A flow velocity vector diagram of vortex chamber was generated, and the vortex structure was analyzed. The results provided an experimental foundation for numerical simulation. The flow characteristics in vortex chamber and in the throat and divergent sections of the nozzle were modeled and simulated. The flow in the vortex chamber conformed to the complex Rankine vortex, and the flow field was divided into three different zones. The vortex core was the primary influence factor for thrust modulation. The resultant velocity reached Mach number 1 before gas arrived at nozzle throat, and the axial velocity still reached Mach number 1 at nozzle throat. Hence, the axial velocity can be used to judge the occurrence of choking at the nozzle throat. The intensity of swirl flow in divergent section of the nozzle was evidently lower than that in vortex chamber and throat. As a result, a lowpressure zone emerged around the central axis, thereby causing thrust losses.
Assessing Tidal Current Power Resources

Tidal current energy is looked upon worldwide as a largely untapped, potentially significant and reliable source of energy. Countries, such as the United Kingdom and Canada, are working towards the implantation of tidal turbine farms in order to exploit this promising form of renewable energy. One of the barriers to further developing tidal energy extraction is the difficulty of accurately assessing the extractable energy or realisable tidal current output of a given site. Various numerical models for site assessments currently exist. Three of them, the Kinetic Energy Flux and two models, named GC05 and V10, which take into account the effect on the flow of the introduction of turbines are described, discussed and used throughout this work. Data regarding 239 channels worldwide have been collected. These data are used to investigate the possible existence of patterns between channel characteristics or parameters and channel potential estimates. New upper limits for the tidal current potentials of the UK and Ireland are calculated using the collected data and the most advanced model V10, and compared to previous values. Finally, resource assessments, based on realisable power, are produced using the V10 model and the Seagen turbine characteristics. For these resource assessments, limits of up to 20% with regards to the blockage ratio and the reduction in flow speed for a given channel are put in place. These results show that a substantial fraction of the upper tidal current potential limit can be realised with only a 20% blockage ratio and a 20% reduction in flow speed for most channels.
Production of methyl bromide in a temperate forest soil

Field enclosure measurements of a temperate forest soil show net uptake of ambient methyl bromide (CH3Br), an important trace gas in both tropospheric and stratospheric ozone cycling. The net flux for 1999 was estimated to be −168 ± 72 μg CH3Br m−2 (negative indicates loss from the atmosphere). Individual enclosure flux measurements ranged from −4.0 to +3.3 μg CH3Br m−2 d−1. Soil consumption of CH3Br was estimated from laboratory soil incubations. Production of CH3Br was calculated as the difference between net flux and predicted consumption. Fungi could be responsible for the production of CH3Br in this temperate forest soil.
Impact of Ethical Leadership on Job Satisfaction and Work-Related Burnout among Turkish Street-Level Bureaucrats: The Roles of Public Service Motivation, Perceived Organizational Support, and Red Tape

Abstract The present study examines the impact of ethical leadership on job satisfaction and work-related burnout (WRB) among street-level bureaucrats through the mediating roles of public service motivation (PSM), perceived organizational support (POS), and red tape by employing social exchange, conservation of resources, social learning, self-determination, and job demands-resources theories. Data from 712 street-level bureaucrats were collected in three waves in Turkey. The findings of structural equation modeling revealed that ethical leadership not only directly but also indirectly affects job satisfaction and WRB. Moreover, ethical leadership was effective in influencing employees’ perceptions of job demands and resources in public sector organizations. The results are consistent with theoretical predictions that PSM is a motivational construct influenced by leadership and job resources, which in turn affects employee outcomes. The results also indicated that job resources (i.e., perceived organizational support) played a more significant role than job demands (i.e., red tape) in determining the effects of ethical leadership on employee outcomes.
Healthy Habits Factors and Stress Associated with Health-Related Quality of Life in a Peruvian Adult Population: A Cross-Sectional Study

Background Healthy habits contribute to the prevention of diseases and, therefore, improve the health-related quality of life of people. However, stress is one of the main risk factors associated with serious health problems in the individual. Therefore, the literature suggests a relationship between healthy habits, stress, and health-related quality of life. Objective To assess the factors of healthy habits and stress associated with health-related quality of life in a Peruvian adult population. Methods A cross-sectional study was conducted with a sample of 540 Peruvian citizens aged between 18 and 60 years. A questionnaire was applied on the Google Forms platform to be completed online, using the “Healthy Lifestyle Questionnaire” and the PSS-4 to assess healthy habits and stress, respectively. Health-related quality of life was evaluated using the EuroQol-5D. Results In the multivariate analysis, stress was the most associated factor with quality of life. Physical activity, drug consumption, tobacco consumption, rest habits, and a balanced diet were healthy habits associated with quality of life. Conclusion Physical activity, rest habits, and a balanced diet improve health-related quality of life, while drug or tobacco consumption and stress are associated with a lower health-related quality of life.
Genomic Characteristics and Functional Analysis of Brucella sp. Strain WY7 Isolated from Antarctic Krill

Antarctic krill (Euphausia superba) is a key species of the Antarctic ecosystem whose unique ecological status and great development potential have attracted extensive attention. However, the genomic characteristics and potential biological functions of the symbiotic microorganisms of Antarctic krill remain unknown. In this study, we cultured and identified a strain of Brucella sp. WY7 from Antarctic krill using whole-genome sequencing and assembly, functional annotation, and comparative genomics analysis. First, based on 16S rDNA sequence alignment and phylogenetic tree analysis, we identified strain WY7 as Brucella. The assembled genome of strain WY7 revealed that it has two chromosomes and a plasmid, with a total genome length of 4,698,850 bp and an average G + C content of 57.18%. The DNA—DNA hybridization value and average nucleotide identity value of strain WY7 and Brucella anthropi ATCC® 49188TM, a type strain isolated from human clinical specimens, were 94.8% and 99.07%, respectively, indicating that strain WY7 is closely related to Brucella anthropi. Genomic island prediction showed that the strain has 60 genomic islands, which may produce HigB and VapC toxins. AntiSMASH analysis results showed that strain WY7 might produce many secondary metabolites, such as terpenes, siderophores and ectoine. Moreover, the genome contains genes involved in the degradation of aromatic compounds, suggesting that strain WY7 can use aromatic compounds in its metabolism. Our work will help to understand the genomic characteristics and metabolic potential of bacterial strains isolated from Antarctic krill, thereby revealing their roles in Antarctic krill and marine ecosystems.
Australian Journal of Teacher Education Teacher Professional Development: Who Is the Learner? Recommended Citation Australian Journal of Teacher Education Teacher Professional Development: Who Is the Learner?

One of the challenges in in-service teacher education is how teachers can be given professional development (PD) that enables them to respond to national curriculum and policy change. In recent years primary teachers in New Zealand have been inundated with Ministry of Education-funded professional development programmes to help them implement a plethora of curriculum policy and reform initiatives. This paper explores how the design and delivery of one PD programme, the Physical Activity Initiative (PAI), positioned and supported teachers as learners. An evaluation of the programme sought data from 25 teachers and 14 advisers to schools. The focus was the impact of the PD on how and what teachers learnt about teaching physical education and how their learning impacted upon their classroom practices. The data highlight the difficulty of accommodating the teacher as a learner, within a " one size fits all " PD model. Little attention was paid to the learning differences among the teachers. It is argued that providers of PD need to understand the unique complex web of contextual factors that impacted upon each teacher, and that each teacher's learning needs and learning approaches vary and this needs to be accounted for in the design and the delivery of PD
Evaluation of Endovenous Laser Ablation in the Management of Varicose Veins

Background The treatment of varicose veins has undergone tremendous changes over the years. High ligation of the saphenofemoral junction (SFJ) and stripping of the great saphenous vein (GSV) have been considered standard treatments for GSV insufficiency for over a century and are still adopted as the preferred method in the majority of surgical centers in North Africa. However, the increase in minimally invasive treatments such as endovenous thermal ablation (EVTA), radiofrequency ablation (RFA), ultrasound-guided foam sclerotherapy, and cryo-stripping has produced excellent results. Most patients who underwent these minimally invasive treatments were satisfied with their outcomes. Methodology and results In this clinical and prospective study, 30 cases (19 male and 11 female) of primary varicose veins underwent endovenous laser ablation (EVLA), and their outcomes were reviewed, and their results were satisfying to the patients. After EVLA with or without sclerotherapy, no major complications occurred (recurrence or recanalization) at the time of the study, although minor complications were quite common and included bruising or ecchymosis, postoperative pain that required analgesics, superficial thrombophlebitis, and skin burns that were very responsive to medical treatment. Conclusion Endovenous laser ablation continues to be a valid minimally invasive method for treating varicose veins with minimal complications and a very short recovery period, which appeals to patients.
Intravascular Ultrasound vs. Fractional Flow Reserve for Percutaneous Coronary Intervention Optimization in Long Coronary Artery Lesions

Background: intravascular ultrasound (IVUS) and fractional flow reserve (FFR) have both been shown to be superior to angiography in optimizing percutaneous coronary intervention (PCI). However, there is still a lack of comparative studies between PCI optimization using physiology and intravascular imaging head-to-head. The aim of this study was to compare the effectiveness of FFR and IVUS PCI optimization strategies on the functional PCI result (assessed with FFR) immediately post-PCI and at 9–12 months after the treatment of long coronary lesions. Methods: This was a single-center study comparing post-PCI FFR between two different PCI optimization strategies (FFR and IVUS). The study included 154 patients who had hemodynamically significant long lesions, necessitating a stent length of 30 mm or more. The procedural outcomes were functional PCI result immediately post-PCI and at 9–12 months after treatment. Clinical outcomes included target vessel failure (TVF) and functional target vessel restenosis rate during follow-up. Results: Baseline clinical characteristics and FFR (0.65 [0.55–0.71]) did not differ significantly between the two groups and the left anterior descending artery was treated in 82% of cases. The FFR optimization strategy resulted in a significantly shorter stented segment (49 mm vs. 63 mm, p = 0.001) compared to the IVUS optimization strategy. Although the rates of optimal functional PCI result (FFR > 0.9) did not significantly differ between the FFR and IVUS optimization strategies, a proportion of patients in the FFR group (12%) experienced poor post-PCI functional outcome with FFR values ≤ 0.8, which was not observed in the IVUS group. At the 9–12 month follow-up, 20% of patients in the FFR group had target-vessel-related myocardial ischemia, compared to 6% in the IVUS group. The rates of TVF and functional target vessel restenosis during follow-up were also numerically higher in the FFR optimization group. Conclusions: The use of FFR PCI optimization strategy in the treatment of long coronary artery lesions is associated with a higher incidence of poor functional PCI result and larger myocardial ischemia burden at follow-up compared to the IVUS optimization strategy. However, this discrepancy did not translate into a statistically significant difference in clinical outcomes. This study highlights the importance of using IVUS to optimize long lesions functional PCI outcomes.
