Published: November 2019

Objetivo: O objetivo deste estudo foi verificar a concordância entre a intensidade estimada pelos treinadores e a percebida por jovens atletas de atletismo.

Método: A amostra foi composta por 50 jovens atletas de atletismo da categoria mirim (13 – 15 anos), sendo 25 meninas e 25 meninos de cinco equipes de atletismo e seus respectivos treinadores. Todos os voluntários foram submetidos ao mesmo protocolo experimental de treinamento para as provas de corrida (75, 250 e 1000 m), salto em distância e arremesso do peso. Para estimar a intensidade da sessão de treinamento, foi usado o método da percepção subjetiva de esforço da sessão.

Resultados: Os resultados encontrados demonstram que em média, há alta concordância entre treinadores e atletas (CCI: 0.76; p < 0.01; n = 50). Contudo, quando analisado por prova, é possível perceber falta de concordância para os treinos de arremesso do peso (CCI: -0.01; p = 0.51; n = 50) e corrida de 1000 m (CCI: 0.24; p = 0.16; n = 50), adicionalmente, em média, para a sessão de treinamento de corrida de 1000 m os treinadores subestimam a intensidade da sessão (p < 0.05).

Conclusão: Treinadores conseguem estimar com precisão as sessões de treinamento de jovens atletas, exceto para os treinos de arremesso do peso e corrida de 1000 m, onde os treinadores tendem a subestimar a intensidade da sessão de treinamento.

Authors: Alvero Cruz Jose Ramon , Vico Guzmán José Francisco , Moya Medina Miguel Angel , Carrillo de Albornoz Gil Margarita , Garcia Romero Jerónimo
Published: November 2019

Objetivo: El objetivo del presente trabajo ha sido comprobar la concordancia entre el valor estimado de VO2máx, a partir del  test de Course Navette, (VO2CN), comparado con la medición directa del consumo de oxígeno en laboratorio (VO2LAB) en un grupo jóvenes de ambos sexos.

Métodos: Participaron en el estudio 28 sujetos, físicamente activos (19 varones y 9 mujeres) de 20.5 ± 2.1 años, peso: 67.1 ± 11.9 kg, talla: 171.0 ± 8.5 cm, IMC: 22.8 ± 2.5 kg/m2. El VO2máx para todos los participantes fue determinado por el método directo en el laboratorio con un test incremental máximo (VO2LAB) y por medio de la estimación del test de Course Navette, (VO2CN) con un intervalo máximo de una semana entre pruebas. Se realizaron estudios de correlación de Pearson y un estudio de concordancia de Bland-Altman entre los valores de VO2LAB y VO2CN.

Resultados: Se comprueba una correlación moderada significativa entre VO2LAB y VO2CN (r=0.53; IC95% (0.19 a 0.75), p=0.003).  Se obtienen unos valores medios de VO2LAB de 46.1 ± 6.7 mL/kg/min y de 47.23 ± 6.1 para VO2CN, no presentando diferencias significativas (p = 0.21). Se comprueba con el análisis de concordancia de Bland-Altman, que no existe error sistemático (diferencia: 1.4889 ml/kg/min (-0.895 a 3.8727), p=0.21) ni error proporcional entre los valores de VO2LAB y VO2CN (Ƭ= -0.089 (-0.33 a 1.89),  p=0.481). Existen diferencias en el VO2LAB entre hombres y mujeres (p=0.01)

Conclusión: Los valores VO2LAB y VO2CN presentan valores bajo-moderados de correlación entre métodos, sin  embargo la estimación del consumo máximo de oxígeno mediante el test de Course Navette es un método adecuado en sujetos jóvenes físicamente activos, sin presentar diferencias en los valores medios, ni error proporcional, aunque se observan amplios límites de concordancia.

Published: November 2019

Objective: The current literature about the body composition of elite football referees is scarce and almost non-existent. Therefore, and in order to establish the level of agreement between bioelectrical impedance analysis (BIA) and dual energy X-ray absorptiometry (DXA) in elite football referees, the aim of this study was to compare fat mass (FM) and fat-free mass (FFM) values measured with these two different methods.

Method: A total of 30 male referees belonging to 1st, 2nd and 2ndB categories, and 36 assistant referees from 1st and 2nd categories in the Spanish national league participated in this study. Total and regional FM and FFM were assessed using a portable BIA analyser TANITA BC 418-MA (Tanita Corp., Tokyo, Japan) and DXA (Hologic Corp. Software version 12.4, Bedford, MA 01730). Agreement between methods was assessed by plotting the results in Bland-Altman graphs and the presence of heteroscedasticity was also examined. Differences between methods were analysed by two-paired samples t-test.

Results: For the whole group, BIA underestimated body fat percentage in 3.87 points (CI 95%=3.22-4.52; p=<0.01) and overestimated kg of total FFM in 3.56 points (CI 95%=3.08-4.05; p=<0.01), however, no heteroscedasticity was shown in any case (all p>0.05).

Conclusions: The present study suggests that according to DXA, BIA values calculated with a non-specific equation are underestimating total FM and, consequently, overestimating total FFM in male elite football referees.

Authors: Nguli Judith Ndinda , Odunga Robert Mukoswa
Published: November 2019

Purpose- Although previous papers have attempted to explore the determinants of financial inclusion, few studies have interrogated the role of innovativeness in financial addition. This study examines the moderating role of entrepreneur innovativeness on the relationship between strategic orientation and financial inclusion
Design/Methodology - We used two indicators to measure financial inclusion; digital financial inclusion scale and traditional financial inclusion scale. Three proxies were used to measure strategic orientation; learning orientation, market orientation, and technology orientation. Survey data obtained from 634 women entrepreneurs was used, and the hypothesis was tested using moderated regression analysis.  
Findings - The empirical results supported the hypothesis that innovative entrepreneur moderates the relationship between strategic orientation and financial inclusion. In particular, the results indicated that at higher levels of entrepreneur innovativeness, learning orientation has a stronger effect on financial inclusion. Similarly, the results also indicated that at high levels of entrepreneur innovativeness, technology orientation affects financial inclusion. In contrast with the other findings showing a positive moderating effect, at higher levels of entrepreneur innovativeness, the impact of market orientation on financial inclusion is low.
Practical Implications - The findings are useful to the government and practitioners for designing policies and training programs geared to increasing the level of financial inclusion among women Small and Medium Enterprises.

The aim of the study was to assess the incidence congenital malformation of congenital malformations in newborns in territories of the Bryansk region with different levels of radioactive, chemical and combined environmental pollution using official statistics for the period 2000-2017. Methods: Shapiro-Wilk test, White test, Wilcoxon T-test, Spearman rank correlation test and regression models were used to study associations between radioactive, chemical and combined pollution and the incidence of congenital malformations in the region and prognosis using the inverse relationship. Results. The incidence of polydactyly, multiple congenital malformations and the amount of de novo birth defects in newborns is significantly lower in the most ecologically favorable districts than in areas with radiation, chemical and combined pollution. For polydactyly - at the level of significance (p), 0.003-0.023 (decrease by 4.7-7.4 times), for the amount of multiple congenital malformations - 0.001-0.054 (2.5-6.8 times) and for amount of de novo birth defects - 0.0010.007 (3.5-4.6 times). Statistically significant differences were found in the incidence of multiple congenital malformations in the conditions of combined pollution in comparison with similar indicators in the territories of radioactive (2.2 times, p = 0.034) and chemical (1.9 times, p = 0.008) pollution (values 1.48; 0.67 and 0.78). A decrease in the long-term trend of frequency of multiple congenital malformations in the period 2000-2017 was revealed on the territories of combined pollution, and increase - on territories of radioactive and chemical pollution. Nevertheless, the predicted values of the frequency of multiple congenital malformations on the territories of combined pollution by 2018-2023 will significantly (p = 0.027) exceed the indicators of the territories of radioactive and chemical pollution by 39.6 and 45.7 % (values 1.18; 0.845; 0.81). Conclusions. Our results suggest synergistic effect of radiation and chemical pollution on the incidence of multiple congenital malformations.

Indonesia is a vast country consisting of 34 provinces and 17,504 islands. Each region has a diverse geographic background. In addition, the uneven development of infrastructure which causes the transport logistics to face various challenges and problems. In the health sector, time is an essential factor in the provision of emergency health needs. Therefore, the distribution of health needs, such as medicines, blood, and medical devices, should be a major concern in improving the quality of health services. In the face of the current distribution of various problems, such as congestion, infrastructure, natural disasters, and the travel time, we propose an alternative solution in solving this problem. The solution is a drone that can perform the unhindered distribution of health needs based on location coordinates of the given location. These drones in the call healthcopter are expected to improve the quality of health services in Indonesia. Healthcopter can be accessed via mobile device applications that can receive requests from various places. This research has produced Healthcopter consisting of drones and application delivery medical needs. The Healthcopter has tested the travel time and speed based on the distance and weight of the load that can be transported by the drone. The heavier the drone load, the longer the travel time and the lower the speed. Similarly to distance, the greater the drone mileage, the longer the travel time and the lower the speed. Keywords: Drone, distribution, health

In connection with rapid urbanization and earthquakes, a huge number of structures have been demolished and generated lots of waste concrete for the last 40 years. Studies on the reclamation of the waste concrete is a pioneer subject for construction sectors in the world. Since the recycling of the waste concrete and reusing of recycled concrete aggregate in the production of new concrete is an important issue for saving of natural resources, economic, sustainable development, significant number of studies have been carried out on this subject. In the scope of this study, a literature review is conducted on the effect of recycled concrete aggregate on mechanical and durability characteristics of small-scale members. Furthermore, structural and seismic performances of full-scale reinforced concrete structural members produced with recycled concrete aggregate are discussed. The test results indicated that the structural members containing recycled aggregate exhibited similar structural performance with their counterparts containing natural aggregates. It was also observed that recycled concrete aggregate did not seem to have an adverse effect on seismic characteristics of the structural members such as ductility.
Earthquakes Effect on the Behavior of Multi-Story RC Building Using Non-Linear Dynamic Analysis
Authors: Olabi M Nadir , Kirtel Osman , Caglar Naci
Published: November 2019

One of the buildings that were designed depending on the old Syrian Code is selected and modeled using SAP2000 by taking its non-linear properties to be checked under dynamical loading. Three earthquake records are taken and applied to the model as Time History loading cases. The dynamical displacement of the top roof of the building and the hysterical diagrams of the relation between base shear and roof displacement is compared and discussed. Asymmetry of shear walls and cores is responsible of the differences in responses of building elements, and insufficient nonlinear modeling of shear walls prevents from finding the real capacity of the system, although comparing pushover curves with hysteric loops from the applied ground motion excitations shows that the building is capable, depending on its old design, to withstand various types of extreme ground motions and earthquakes.

The objective of this study was to assess Lebanese population exposure to trace elements (TEs) via white pita consumption. A survey of white pita consumption was achieved among one thousand Lebanese individuals, grouped into adults (above 15 years old, men, and women) and young people (6–9 and 10–14 years old). The most consumed pita brands, labeled B1, B2, and B3, were selected. Levels of TEs (i.e., As, Cd, Co, Cr, Hg, Ni, and Pb) in B1, B2, B3 pitas were measured. The highest contents of TEs in pitas were: Ni (1292 µg/kg) and Co (91 µg/kg) in B1; As (400 µg/kg) and Cd (< 15 µg/kg) in B2; Cr (363 µg/kg), Pb (260 µg/kg), and Hg (0.89 µg/kg) in B3. The pita brand B3 was the source of the highest TEs exposure, except for Ni for which it was B1. Daily exposures to TEs due to the fact of pita consumption were compared to safety levels. There were no safety concerns for Hg, Cd, Cr or Co (except the 95th percentile of 6–9 years old). An excess of the Ni tolerable daily intake was observed for the most exposed populations. The very low margins of exposure for As and Pb suggest a worrying risk for the Lebanese population.

On a cuspate sandy foreland, the cycle of beach erosion and recovery is driven by the bi-directional approaches of wave climates, which also determine its specific shape. This work describes the seasonal morphodynamics of the Maspalomas natural cuspate foreland over a period of six years. This area, located in the south of Gran Canaria Island, consists of two beaches with different shoreline orientation, Maspalomas Beach and El Inglés Beach, converging to La Bajeta Tip at the head of the foreland. Shoreline variability and three-dimensional beach changes were measured and coupled to wave energy and longshore currents. From wave analysis, 112 storm events were identified over the period in focus. These events most frequently came from the northeast and in summer, which is consistent with the strong northeasterly trade winds between April and September. However, the strongest storms from the southwest were found to be the main cause of intense shoreline retreats, of up to 100 and 200 m, at Maspalomas Beach and La Bajeta Tip, respectively. The Maspalomas Beach sector showed interannual variability, with a general trend of erosion, whereas La Bajeta Tip demonstrated faster beach recovery. In contrast, El Inglés Beach sector presented a stable shoreline, in spite of the occurrence of wave storms approaching from northeast or southwest. Consequently, results indicate that energetic waves play a significant role in shoreline dynamics and Maspalomas landform shape. Post-storm sand recovery processes do not only occur during calm periods, but also during energetic events. The findings of this study have improved the understanding of seasonal and multiannual cuspate foreland morphodynamics, setting the groundwork for a potential long-term evolution model of Maspalomas coast.

This study on hydrodynamic coefficients of a column-stabilized fish cage under wave action plays an important role in the anti-wave design of cages. The regular wave test was used to study the horizontal wave force of the jacket and column-stabilized fish cage under different wave heights, periods, and incident angles; the finite element model of the jacket and the column-stabilized fish cage was established according to the test model. On the basis of the calculation of the finite element model, combined with the wave force obtained from the experiment, the hydrodynamic coefficients of the structure was fitted by the least squares method, and then the drag force, inertial force, and total force of the structure under different conditions were calculated. The results show that the hydrodynamic coefficients of the jacket and netting under the wave condition were more obvious with the change of the KC number and wave incident angles. And as the wave height increased, the drag force, the inertial force, and the proportion of the drag force to the horizontal wave force both increased. When the wavelength was large, the same trend occured as the wave period increased. When the wave incident angles were different, the forces of the jacket and the column-stabilized fish cage were always small in lateral low-frequency waves, which is consistent with the change law of hydrodynamic coefficients of the jacket and netting.

Oil-infused ‘slippery’ polymer surfaces and engineered surface textures have been separately shown to reduce settlement or adhesion strength of marine biofouling organisms. Here, we combine these two approaches in fluorogel surfaces infused with perfluorinated oils, via a facile photo-embossing method that allows the generation of a micro-scale surface relief structure while retaining the properties of lubricant-infused materials. Testing of these surfaces against a range of marine fouling challenges in laboratory assays demonstrated that when the volume percentage of perfluorinated oil was high, adhesion strengths of attached barnacles and biofilms were low. However, diatoms adhered strongly to test surfaces, highlighting the need to explore different combinations of polymer and oil for such surfaces. Furthermore, the tested surface structures increased settlement and adhesion in the assays, demonstrating the need to optimize any surface structure for specific applications. Nevertheless, the results show the feasibility of combining multiple approaches to create future antifouling technologies.

Fall detection is a critical task in an aging society. To fulfill this task, smart technology applications have great potential. However, it is not easy to choose a suitable smart technology application for fall detection. To address this issue, a fuzzy collaborative intelligence approach is proposed in this study. In the fuzzy collaborative intelligence approach, alpha-cut operations are applied to derive the fuzzy weights of criteria for each decision maker. Then, fuzzy intersection is applied to aggregate the fuzzy weights derived by all decision makers. Subsequently, the fuzzy technique for order preference by similarity to the ideal solution is applied to assess the suitability of a smart technology application for fall detection. The fuzzy collaborative intelligence approach is a posterior-aggregation method that guarantees a consensus exists among decision makers. After applying the fuzzy collaborative intelligence approach to assess the suitabilities of four existing smart technology applications for fall detection, the most and least suitable smart technology applications were smart carpet and smart cane, respectively. In addition, the ranking result using the proposed methodology was somewhat different from those using three existing methods.

Although numerous research efforts have been made for the last two decades, the chronic problems of lithium-sulphur batteries (LSBs), i.e., polysulfide shuttling of active sulphur material and surface passivation of the lithium metal anode, still impede their practical application. In order to mitigate these issues, we utilized polyimide functionalized glass microfibers (PI-GF) as a functional separator. The water-soluble precursor enabled the formation of a homogenous thin coating on the surface of the glass microfiber (GF) membrane with the potential to scale and fine-tune: the PI-GF was prepared by simple dipping of commercial GF into an aqueous solution of poly(amic acid), (PAA), followed by thermal imidization. We found that a tiny amount of polyimide (PI) of 0.5 wt.% is more than enough to endow the GF separator with useful capabilities, both retarding polysulfide migration. Combined with a free-standing microporous carbon cloth-sulphur composite cathode, the PI-GF-based LSB cell exhibits a stable cycling over 120 cycles at a current density of 1 mA/cm2 and an areal sulphur loading of 2 mgS/cm2 with only a marginal capacity loss of 0.099%/cycle. This corresponds to an improvement in cycle stability by 200%, specific capacity by 16.4%, and capacity loss per cycle by 45% as compared to those of the cell without PI coating. Our study revealed that a simple but synergistic combination of porous carbon supporting material and functional separator enabled us to achieve high-performance LSBs, but could also pave the way for the development of practical LSBs using the commercially viable method without using complicated synthesis or harmful and expensive chemicals.

Cu2ZnSnS4 (CZTS) has been recognized as a promising thin-film absorber material of chalcopyrite-related solar cells. A two-stage method for fabricating CZTS films using CZTS nanoparticles was developed. Nanocrystal inks fabricated by a ball-milling method was utilized to °C deposit CZTS precursors by spin-coating approach. The CZTS precursors were annealed in the sulfur atmosphere under different annealing temperatures ranging from 550 °C to 650 °C. Influences of annealing temperature on grain growth, composition, crystallinity, and photovoltaic properties of CZTS films were characterized. With the increase of annealing temperature, grain growth was enhanced, while the sulfur atomic ratio fist increased then decreased. The crystallinity of the films was significantly improved after the annealing, and the obvious peak of the secondary phase of ZnS, were observed from the X-ray diffraction results, when the annealing temperature increased to 625 °C. However, the secondary phase was not detected from the surface Raman spectrum. Through comparing the Raman spectrum of different areas of the CZTS film, secondary phases of ZnS and SnS were observed, indicating the decomposition of CZTS films, due to the high temperature. The highest conversion efficiency of 7.5% was obtained when the annealing temperature was 600 °C.

The objective of this article is to investigate the impacts of thermo-diffusion effect on unsteady axisymmetric Casson flow over a time-dependent radially stretching sheet with a multi-slip parameter and the force of chemical reaction. We employed an established similarity transformation to this non-linear partial differential system to convert it into a system of ordinary differential equations. The numerical results are attained for this system by using KELLER-BOX implicit finite difference scheme. It has great reliability and accuracy even a very short time period for computational simulation. The impacts of influential flow parameters on fluid flow are sketched through graphs and the numerical results are thoroughly argued. The temperature, velocity and wall concentration control parameters are analyzed. (i) It is witnessed that chemical reaction is not favorable to enhance the velocity profile. (ii) Multi-slip parameters vary inversely with velocity profile. (iii) The fluid concentration in its boundary layer decreases with the increase of heavier species, the parameter of the reaction rate and the exponent of power law for fluids having Prandtl number = 10.0, 15.0, 20.0 and 25.0. Moreover, the skin-friction-coefficient factor and Nusselt-number are compared with the published work. A strong numerical solution agreement is being observed.
