Teaching Game for Understanding in Physical Education: A Theoretical Framework and Implication

ABSTRACT: The primary purpose of the present study was to investigate the effects of Teaching Games for Understanding (TGfU) approach to improve students’ learning outcome of tactical game performance in physical education. By applying the constructivism learning theory, the study wants to investigate whether the students learning outcome in tactical game performance can be improved with the TGfU approach. The participants in this study were 10 years old primary physical education students. The Game Performance Assessment Instrument (GPAI) was used to measure students' tactical understanding of game performance. The results of the validation studies showed that the instruments developed for the purposes of this project were valid indicators of tactical game performance. The ANCOVA results revealed that there was a significant difference between the students who were exposed to TGfU approach and students with traditional skill approach on the post-test (F [1, 69] = 248.83, p < .05). This result indicated that the experimental group with TGfU approach has significant main effects on student learning outcome compared to the traditional skill approach. The findings of this study showed that constructivism theory improved primary physical education students learning outcome in physical education.

Exosomal miRNA-223-3p as potential biomarkers in patients with cerebral small vessel disease cognitive impairment

Background Cerebrovascular disease is a common clinical illness. Many patients with cerebrovascular disease can be accompanied by cognitive impairment. The exosomal microRNA (miRNA)-223-3p is related to vascular endothelial injury, synaptic function, inflammatory response, and other mechanisms. In this study, we investigated the levels of plasma exosomal miRNA-223-3p in patients with cerebral small vessel disease (CSVD), in order to determine whether it could be used as a more accessible potential biomarker for the early diagnosis and treatment of CSVD. This study aimed to explore whether the development of cognitive impairment can be explained by differentially expressed miRNA-223-3p by detecting the level of miRNA-223-3p, which is abundant in peripheral blood exosomes related to cognitive impairment in CSVD. Methods The three groups of participants included 40 patients with CSVD cognitive impairment (CSVDCI), 38 patients with CSVD, and 35 normal controls (NC). The real-time polymerase chain reaction (RT-PCR) was used to detect the expression level of blood exosomal miRNA-223-3p. In addition, we also studied the relationship between exosomal miRNA-223-3p and blood Hcy and C-reactive protein (CRP). Receiver-operating characteristic (ROC) curve analysis was used to evaluate the diagnostic efficacy of plasma exosomal miRNA-223-3p. Results The expression of exosomal miRNA-223-3p in CSVD increased, and the expression of miRNA-223-3p increased significantly with the occurrence of cognitive impairment. Exosomal miRNA-223-3p was positively correlated with the expression levels of Hcy and CRP in the blood. Conclusions The expression of plasma exosomal miRNA-223-3p is associated with the development of cognitive impairment in patients with CSVD. It may be involved in the pathogenesis of CSVD and cognitive impairment, and can be used as a sensitive predictive biomarker.
Input-output linearization and zero-dynamics control of three-phase AC/DC voltage-source converters

Nonlinear differential-geometric techniques are proposed for the design of a feedback controller for three-phase voltage-source pulsewidth modulation (PWM) AC/DC boost converters under a cascade control structure. The input-output linearizability of the system modeled in d-q synchronous reference frames is examined. The results lead to a decoupled d-q current control scheme. For the internal DC-bus voltage dynamics (zero dynamics), by considering the d-axis current command as control input and using a square transform on DC-bus voltage, it is shown that this remaining system contains an input memoryless nonlinearity of conic sector type and satisfies the conditions for a Lur'e plant. This suggests a new outer-loop control strategy to control the square of the DC output voltage, rather than DC output voltage itself, utilizing a simple proportional plus integral (PI) controller cascaded to the d-axis current loop. Since most results do not consider the control of zero dynamics, the strategy for the control of zero dynamics via cascade control structure may provide valuable insight for the design of input-output linearized systems in which zero dynamics contain some desired control variables. The absolute tracking concept for Lur'e plants is introduced to prove the global tracking capability with zero steady-state error of the voltage loop. The controlled PWM AC/DC converter has the features of global stability, fast (exponential) tracking of DC-bus voltage command with zero steady-state error, asymptotic rejection of load disturbance, robustness against parameter uncertainties and decoupled dynamical responses between d and q current loops. Also, measurement of load current is not required. All these features are confirmed via laboratory experiments on a 1.5 kVA PC-based controlled prototype.
A Study on AHOF400 Which is Possible Car to SUV Compatibility Evaluation

Research on the evaluation method for vehicle compatibility has continued among passive safety industries in recent years. The National Highway traffic Safety Administration (NHTSA), which has jurisdiction over automobile safety in the United States, is studying Average Height of Force 400 (AHOF400) as a new criteria to evaluate interaction between vehicles to improve compatibility performance. In this paper, the target value of AHOF400 was assumed to be Part581 zone, which is the front bumper height of a passenger car. A basic study was carried out using finite element modeling of an existing vehicle model and a real vehicle crash test in order to determine how to practically modify the vehicle structure of an sport utility vehicle (SUV). As a result, it was determined that the height of the Front Side Member of an SUV should be lower than that of a passenger car in some cases. This is different from the original aiming point that car-to-car interaction would be improved by restriction of AHOF400, which makes the height of front end structures the same level. As a way to solve the concern, an evaluation area of barrier load cells height which is appropriate to calculate AHOF400 was studied
The study and optimization of new micropattern gaseous detectors for high rate applications

We performed a new series of systematic studies of gain and rate characteristics of several micropattern gaseous detectors. In contrast to earlier studies, these measurements were done at various pressures, gas mixtures, at a wide range of primary ionization and also when the whole area of the detectors was irradiated with a high intensity X-ray beam. Several new effects were discovered common to all tested detectors, and which define fundamental limits of their operation. Results of these studies allow us to suggest some concrete ways of micropattern detectors improving.
Comparison of Effects of N95 Respirators and Surgical Masks to Physiological and Psychological Health among Healthcare Workers: A Randomized Controlled Trial

Since the onset of the coronavirus disease 2019 pandemic, wearing facemasks has become more important for healthcare workers. This study aimed to investigate and compare the influence of wearing N95 respirators and surgical masks for 8 h on physiological and psychological health. Sixty-eight healthcare workers were randomly assigned to the N95 respirator or surgical mask groups. Physiological parameters of participants were measured by Tensor Tip MTX at baseline and at the 2nd, 4th, 6th and 8th h of wearing the facemasks. The symptoms after wearing facemasks were also determined via the questionnaire. There were no significant changes in physiological parameters at most time checkpoints in both groups. Significant differences were observed in terms of heart rate at the 8th h, time trends (adjusted difference of least squares means were −8.53 and −2.01), and interaction of time and mask type between the two groups (p-value for interaction was 0.0146). The values of these physiological parameters were within normal ranges. The N95 respirator group had significantly higher incidences of shortness of breath, headache, dizziness, difficulty talking and fatigue that spontaneously resolved. In conclusion, healthcare workers who wore either N95 respirators or surgical masks during an 8 h shift had no obvious harmful effects on physiological and psychological health. Additionally, the N95 respirator group did not show a higher risk than the surgical mask group.
A preliminary study on environmental performances of pocket parks in high-rise and high-density urban context in Hong Kong

This article reports the results of an empirical study on summertime environmental performances of a pocket park in Hong Kong. The results suggest that (i) wind condition has a critical impact on outdoor air temperature (Ta), especially in a tropical area like Hong Kong and (ii) building geometry is significantly related to outdoor Ta in Hong Kong. The shading effect from buildings may be more important than shading and evapotranspiration effect of greenery in the unique urban context of Hong Kong. Copyright , Oxford University Press.

High Temperature Overhung Pumps: Cooling Optimization

A typical industrial application of high temperature pumps involves handling of fluids up to 400 °C. This is critical for pump bearing housing, where thermal dissipation is not effective due to geometric configuration. Therefore, without any external cooling system, bearings and lubricating oil temperatures can exceed allowable values prescribed by both API 610 Reference Standard [1] and bearing manufacturer [2]. Particularly, for a overhung pump, when pumped fluid temperature is above 200 °C, external cooling system is necessary and water is usually used for this purpose. Consequently, water availability must be taken into account when considering pump’s location, which is particularly difficult in desert areas. From these considerations was the idea to enhance the heat transfer of the pump support, in order to avoid any need of cooling water. The problem has been dealt with numerical analysis and experimental tests. First, we have considered the original support in the most critical situation, the stand-by condition, where no forced convection (fan) is effective. From the results pertaining to currently used support, we have got the hints to improve heat transfer by a full redesign. Finally an experimental validation has been set up. The measures gained allow us to validate hypothesis taken into consideration in the numerical simulation.Copyright © 2005 by ASME
Holographic Optical Lenses Recorded on a Glassy Matrix-Based Photopolymer for Solar Concentrators

Global warming is a very topical issue, therefore the search for new renewable energy sources is considered of fundamental importance. Among these, solar energy offers great possibilities considering that the amount of sunlight hitting the Earth ‘s surface in an hour and a half is enough to meet the world’s electricity consumption for a complete year. Generally, solar concentrators are used to collect the solar radiation and to concentrate it at a single focal point. These devices consist in a set of mirrors or mechanical structures to reduce the area of a photovoltaic cell, which is typically very expensive. Volume transmission phase holographic optical elements could be opportunely designed and realized to obtain a simple, lightweight, compact and inexpensive planar solar concentrator. With the aim of bringing scientific attention to this still developing topic, in this work we critically report a complete investigation on a new photopolymeric material obtained by sol-gel reactions used as possible recording material for volume holographic solar concentrators; as a proof of concept, both terrestrial and extreme environments, such as space, are considered as potential applications.
Ground/Wall Effects on a Tilting Ducted Fan

Mini-vertical take-off and landing aircraft have a wide range of potential applications in urban areas. In flights in confined spaces, however, the aerodynamics of the lifting devices (e.g., tilted ducted fans) change which significantly affects the flight performance. Therefore, for a successful flight, a model is required to provide the control system with the environmental effects on the lifting devices in real time. This paper presents the study performed on a tilted ducted fan to characterize ground/wall effects and develop a practical model for online flight control. For this, computational fluid dynamic simulations were performed in Fluent, for a ducted fan at different distances from ground/wall and with different tilt angles. The incompressible Reynolds Averaged Navier Stokes (RANS) equations, with the standard k-ε model and the non-equilibrium wall function, were solved. To reduce the complexity of meshing, the fan was represented by Virtual Blade Model (VBM). A comprehensive study was performed to show that, by using the method of images and representing the fan as a single potential dipole, the fan performance can be predicted accurately on a practical range of operation. The developed potential flow model highly reduces the computational requirements and is practical to use for online semi-autonomous or autonomous navigation of ducted fan aerial vehicles.
Impact of Social Network Type and Structure on Modeling Normative Energy Use Behavior Interventions

AbstractOccupant behavior has a substantial impact on the total energy consumption in buildings. To reduce consumption much work has been done investigating behavioral energy-use interventions (e.g., feedback). Being able to accurately identify effective interventions for specific buildings or communities of buildings based on local conditions has significant implications for reducing energy consumption and demand in buildings. Therefore, recently researchers have begun developing predictive models of these behavioral interventions. However, limited consideration has been given to the importance that modeling assumptions (regarding social network type and structure) have in determining impact on intervention outcome. In this paper, an integrated model that combines established social-psychological principles of social influence and cultural norm diffusion with building social network profiles is developed and tested to examine the effect of social network type and structure on interventions.

Expression of Endogenous Retroviral RNA in Prostate Tumors has Prognostic Value and Shows Differences among Americans of African Versus European/Middle Eastern Ancestry

Simple Summary Endogenous retroviruses (ERVs) are viral sequences that have been incorporated into the human genome over millions of years via integrations in germ-line cells. In this study, we investigated whether the expression of ERVs was associated with two different aspects of prostate cancer (PCa). First, Black American men have a higher incidence and poorer outcome of PCa compared to White men. We identified differences in ERV expression among prostate tumors between men of primarily African versus primarily European or Middle Eastern ancestry, which may be associated with differences in the mechanism of cancer progression in patients of these distinct ancestries. Second, we determined whether ERV expression might be correlated with the progression of disease, regardless of ancestry. We identified the ERV expression signatures that correlated with biochemical relapse among PCa patients of all ancestries, indicating that ERVs may be useful for identifying cancer patients at greatest risk of progression. The utility of ERV expression for studying cancer progression may extend to other cancers. Abstract Endogenous retroviruses (ERVs) are abundant, repetitive elements dispersed across the human genome and are implicated in various diseases. We investigated two potential roles for ERVs in prostate cancer (PCa). First, the PCa of Black Americans (BA) is diagnosed at an earlier median age and at a more advanced stage than the PCa of White Americans (WA). We used publicly available RNA-seq data from tumor-enriched samples of 27 BA and 65 WA PCa patients in order to identify 12 differentially expressed ERVs (padj < 0.1) and used a tissue microarray of the PCa cores from an independent set of BA and WA patients to validate the differential protein expression of one of these ERVs, ERV3-1 (p = 2.829 × 10−7). Second, we used 57 PCa tumors from patients of all ancestries from one hospital as a training set to identify the ERVs associated with time to biochemical relapse. A 29-ERV prognostic panel was then tested and validated on 35 separate PCa tumors from patients obtained in two different hospitals with a dramatic increase in prognostic power relative to clinical parameters alone (p = 7.4 × 10−11). In summary, ERV RNA expression differences in the prostate tumors of patients of different ancestries may be associated with dissimilarities in the mechanism of cancer progression. In addition, the correlation of expression of certain ERVs in prostate tumors with the risk of biochemical relapse indicates a possible role for ERV expression in cancer progression.
Smart hexagonal truss systems exhibiting negative compressibility through constrained angle stretching

Negative compressibility is the ability to expand in at least one dimension rather than shrinking upon the application of an externally applied hydrostatic pressure. It is shown that, contrary to current perception, negative linear compressibility may be obtained from re-entrant hexagonal truss systems of specific geometric features which deform through non-equal changes in the lengths of the cell walls when deforming through a constrained angle stretching rather than other modes of deformation (such as flexure or hinging, modes of deformation that also lead to auxetic behaviour in honeycombs). Negative compressibility is predicted in the vertical direction for particular re-entrant geometries of this smart hexagonal truss system when the vertical ribs are much stiffer than the inclined ribs.
A MOEMS Accelerometer Based on the Magneto-Optical Rotation Effect

A new principle MOEMS accelerometer based on the magneto-optical rotation effect is developed. The design of the magnetic film integrates with the proof mass, using a magneto-optic crystal to detect the magnetic field changes induced by the external acceleration to produce the magneto-optical rotation effect. By detecting the optical rotation angle, the high precision measurement of the acceleration is realized. The structure of the accelerometer was fabricated through structural design, simulation and micro-nano processing technology. The test results show that the noise spectral density of the MOEMS accelerometer is <inline-formula> <tex-math notation="LaTeX">$10.5\mu \text{g}/\surd $ </tex-math></inline-formula>Hz at 1Hz, the bias instability is <inline-formula> <tex-math notation="LaTeX">$37.6\mu \text{g}$ </tex-math></inline-formula> and the output sensitivity is 330.2mV/g.
Gut Microbiota Composition across Normal Range Prostate-Specific Antigen Levels

Animal studies have shown the interaction between androgens and the gut microbiome directly and indirectly; however, limited evidence from human studies is available. To evaluate the association between prostate-specific antigen (PSA) levels within the normal range, reflective of androgen receptor activity, and the gut microbiota composition, a cross-sectional analysis was performed in 759 Korean men aged between 25 and 78 years with normal PSA levels of ≤4.0 ng/mL. We evaluated the biodiversity of gut microbiota as well as the taxonomic and functional signatures associated with PSA levels using 16S rRNA gene sequencing data. PSA levels within the normal range were categorized into three groups: lowest quartile (G1), interquartile range (G2, reference), and highest quartile (G3). The G3 group had higher microbial richness than the G2 group, although it was dominated by a few bacteria. An increase in Escherichia/Shigella abundance and a reduction in Megamonas abundance in the G3 group were also detected. A U-shaped relationship was observed between the three groups across most analyses, including biodiversity, taxonomic composition, and inferred pathways in the gut microbiota. This study showed different microbiota patterns across PSA levels within the normal range. Further studies are required to elucidate the role of microbiota in regulating PSA levels.
