Authors: Albarghouthi Mohammed , Qi Baomin , Wang Chengbo , Abbad Muneer
Published: August 2020

Enterprise resource planning (ERP) systems are integrated information systems inter-connecting different functional areas within organisations. It has been widely implemented by large manufacturers globally to enhance operational excellence. However, ERP in the Higher Education sector is less accepted and research in this area still remains at its infancy. Although many higher education institutions (HEIs) have implemented ERP solutions or are in the course of implementing the ERP systems, the failure rate ERP projects within HE is much higher than in other sectors. Through critically examining the existing literature the aim of this research is to develop an extended technology acceptance model (TAM) taking into account the critical factors of ERP adoption for HEIs. Two categories of these factors have been identified from literature based upon a conceptual model is developed. It was clear from reviewing the literature that the main categories of factors that have been studied extensively and shown to be key to understanding ERP adoption and acceptance are: the individual-related factors such as computer self-efficacy and organisational-related factors such as top management.

It is very important for a modern specialist to be aware of information technolo-gies and effectively apply them in their professional activities. Thus, the use of electronic learning tools contributes to the motivation of students and allows them to more deeply master the learning material through video and audio files com-pared to a paper textbook. The purpose of the study is to evaluate the effective-ness of the introduction of the experimental electronic textbook in physical educa-tion classes. The proposed textbook consists of 7 modules. The goal, objectives, as well as the tasks for their implementation and test tasks to consolidate the ma-terial learned, have been developed for each module. During January-May 2019, at Aktobe Regional State University named after K. Zhubanov, there was a peda-gogical experiment to introduce an electronic textbook in physical education. The experiment involved 28 young men. The results showed that the introduction of an electronic textbook in the experimental group has a more positive effect on physical fitness compared to the control group.

Published: August 2020

Learning to code is considered as a difficult and challenging task for a significant number of novice programmers in programming education. Novice programmers have to acquire different skills such as problem solving, program design, comprehension, and debugging at the same time. On the other hand, most introductory programming courses focus more on syntax of the programming language. In this study, we developed and introduced a ‘PROBSOL’ application in three different learning systems (E-learning, M-learning and Game-based learning) to enhance the problem solving skills of novice programmers in an introductory programming (IP) course. A survey was conducted with the IP students to determine their perception about all the three applications in the IP course. Gender differences were determined by comparing both female and male students’ responses for each question in the survey. The results of comparison show that male students were more satisfied with all the three applications compared to female students. Both female and male students perceived that all the three applications are user-friendly, enabled them to accomplish tasks more quickly, and enhanced their learning productivity. Overall, both male and female students appreciated all the three applications in the teaching and learning process of the IP course. This study implies that instructors can also use all the three applications as an additional teaching tool in the teaching and learning process of programming education.

Published: August 2020

In the new era, college teachers should improve their teaching ability, espe-cially in terms of adaptability. However, most college teachers lack sufficient adaptive teaching ability, failing to create an adaptive teaching environment. To solve the problem, this paper explores deep into the extension strategies for improving the adaptive teaching ability of college teachers. First, the problems of college teachers in adaptive teaching were identified, and the key aspects of adaptive teaching ability were enumerated theoretically. On this basis, several extension strategies were put forward to improve the adap-tive teaching ability of college teachers. To evaluate the improving effect, the authors developed an evaluation model for the adaptive teaching ability of college teachers based on the extension theory. Overall, this paper fully ex-plores the improvement of adaptive teaching ability of college teachers via theoretical analysis and modelling. The research results boast good applica-tion prospects.

Authors: Chen Yihui , Yang Mingli
Published: August 2020

The teaching ability of College Teachers is regarded as one of the core competencies and a critical indicator for measuring comprehensive strength for a college. However, its evaluation process is a highly complex system decision-making, for there are various factors that influence on the assessment of for the College Teachers’ the teaching ability. The traditional methods have drawbacks of strong subjectivity, so they are difficult to correctly evaluate the teaching ability of College Teachers, resulting in decrease of measurement accuracy. Based on the analysis of the relevant factors, this paper presents an intelligent design based neural network model of discrete Hopfield for the measurement and analysis of College Teachers' teaching ability. Firstly, a Hopfield neural network model for the measure analysis of the teaching ability is established, and eleven measure analysis indexes are selected as input information of the Hopfield neural network model. Secondly, the College Teachers' teaching ability grades are chosen as the model output, then the input and output model based on the relationship among the self-learning abilities of neural network is established. Finally, the simulation experiment is obtained by using MATLAB. The simulation results show that the model has the characteristics of high efficiency, objectivity and fairness, which can meet the requirements of the measurement and analysis of College Teachers' teaching ability.

Published: August 2020

Advances in technology have allowed mobile devices to be used for learning purpose. The use of tablets in mobile learning has the potential to enhance learning, contributing to increased motivation and knowledge acquisition. However, without careful planning and support for learning content, students may not have the behavioural intention to use tablets in their learning. Previous studies have focused on the use of learning applications installed in the tablets. There is a lack of research on students' behavioural intentions to use tablets in learning. The partial least squares regression approach and the Unified Theory of Acceptance and Use of Technology (UTAUT) were used in this study to explore students’ behavioural intention to use the tablet in learning. This study was conducted in a private school in Malaysia. A total of 170 participants were enrolled in this study. The results showed that most of the hypotheses of the study were not supported and further revealed that the construct of performance expectancy was the only determinant of students’ behavioural intentions to use the tablet in learning.

Authors: Strzelecki Artur
Published: August 2020

This paper presents an application of developers' and users' dependent factors in the app store optimization. The application is based on two main fields: developers’ dependent factors and users’ dependent factors. Developers’ dependent factors are identified as: developer name, app name, subtitle, genre, short description, long description, content rating, system requirements, page url, last update, what’s new and price. Users’ dependent factors are identified as: download volume, average rating, rating volume and reviews. The proposed application in its final form is modelled after mining sample data from two leading app stores: Google Play and Apple App Store. Results from analyzing collected data show that developer dependent elements can be better optimized. Names and descriptions of mobile apps are not fully utilized. In Google Play there is one significant correlation between download volume and number of reviews, whereas in App Store there is no significant correlation between factors.

Published: August 2020

— In these days of online commerce, we need to know the real behavior of consumers in physical stores: the points of sale must anticipate the purchasing decisions of consumers in order to be able to offer the best buying experience as well as tailor the marketing variables to the specific needs of each consumer. This is where retail intelligence emerges, especially in the textile industry, as a potential technology that makes use of extremely large data sets (“big data”) to engage potential customers better in order to increase company sales. The objective of this study is to show how big data can be effectively leveraged for direct and clear commercial purposes in textile stores. The development of research is based on the analysis of the application of systematic observation of consumer behavior in three main streets in Spain known for textile retail stores and interpreting their differences. The results show that data collected through various point-of-sale devices have a significant influence on retail revenue. The differences between commercial areas and the relative attractiveness of the textile trade in different cities are also borne out by the results. The main conclusions point to the need to improve the profitability of textile fashion stores on the back of promotional tactics that focus on the number of estimated customers and the possibilities of selling to them. All of the aforesaid have a significant influence on how advertising planning is carried out for retail stores.

Authors: Houmer Meriem , Ouaissa Mariya , Ouaissa Mariyam , Hasnaoui Moulay Lahcen
Published: August 2020

In Intelligent Transport Systems (ITS), Vehicular Ad-hoc Networks (VANET) play an essential role in improving road safety and traffic efficiency. Nevertheless, due to its special characteristics like high mobility, large size of the network and dynamic topology make routing of data in the vehicular ad hoc network more challenging. The problem in these networks is to determine the routing protocol best suited to this environment, and then secure it to provide optimal and secure routing for the data. Recently, position-based routing protocol has been developed by researchers to be a very interesting routing technique for communication between vehicles. In this paper, we propose an secured and enhanced version of the Greedy Perimeter Stateless Routing (GPSR) protocol. This protocol consists of two modules: (i) To implement an improvement of GPSR routing protocol which minimizes transfer delays and control messages. (ii) To deal with security issues, we have proposed a solution that combines between an improved Diffie-Hellman algorithm for reliable key exchange and the hash function based Message Authentication Code (MAC) for the verification of the authentication and integrity of GPSR packet. The proposed solution was checked by the security protocol verification tool, Automated Validation of Internet Security Protocols and Applications (AVISPA), which indicated that it is a very secure level. Simulation results showed that our proposed compared to the original GPSR offers better performances.
Consumer Acceptance of App Push Notifications: Systematic Review on the Influence of Frequency
Authors: Wohllebe Atilla
Published: August 2020

Using push notifications, companies can address their smartphone app users with advertising messages. Each of these notifications can mean added value for smartphone users in terms of content, but also disruption and interruption. It is therefore important for advertisers to understand how the frequency of message delivery influences consumer acceptance. The systematic review is based on the PRISMA method and initially identifies a total of 18,725 potentially relevant scientific papers. The 17 research articles included in the qualitative synthesis show that push notifications are suitable for encouraging users to use an app and establish new habits. App usage increases with frequency, with particularly active users tolerating higher frequencies. At the same time it is also shown that too high a frequency can be perceived as disturbing and users should therefore be given the opportunity to determine the frequency with which they receive notifications. A gap in research has been identified in particular in studies that look at real observed behaviour of app users instead of behaviour reported via questionnaires and examine the interaction of frequency, content and presentation of notifications.
Nursing Care Systematization: Applicability to Primary Care
Authors: Marcomini Emilli Karine , Paula Nanci Verginia Kuster de , Raimondi Daiane Cortez
Published: August 2020

Nursing Care Systematization (NCS) is an organized and systematized process that concerns nursing professionals who provide quality assistance, being a mandatory tool in all health centers. Despite this factor, there is a visible resistance from nursing to the operationalization of a systematized care. Thus, the present study aims to analyze the applicability of nursing care systematization and the knowledge that primary care nurses have of this process. This is a descriptive, cross-sectional study with quanti-qualitative approach, conducted with nurses working in primary care teams from a regional health zone in the state of Paraná, Brazil. Out of the 44 participant nurses, only 20.5% claimed to take all steps in the nursing process during their care practice, and 43.2% do not know about the Resolution of the Federal Nursing Council that addresses NCS application. This low NCS applicability is worrisome, since it is related to the quality, resolution and security of care provision. The applicability of the systematization within the assessed teams is quite fragmented and small; besides, their NCS knowledge is insufficient considering that this is such a relevant tool to a nurse’s professional practice. It is possible to notice numerous fragilities and difficulties in the application of NCS to primary care, with highlight to time availability, overworked nurses, and need for training.

Published: August 2020

This study aimed to learn about the conditions of access to health services that seniors living in rural areas have, as well as their satisfaction. This is a qualitative, descriptive and exploratory research conducted in a municipality located in the southern region of Rio Grande do Sul, Brazil. It included 19 elderly individuals registered in three Basic Health Units organized in the form of Family Health Strategy. Data were collected between July and August 2018 through semi-structured interviews, which were analyzed based on Minayo's operational proposal. Afterwards, two categories were defined: "Access to health services used by elderly residents of rural areas" and "Satisfaction with health services used by elderly residents of rural areas". Concerning access, many are the difficulties faced, such as long distances to be traveled until arriving at a health service, poor road conditions, limitations related to public transport days, timetables and itineraries, lack of human and material resources, and long waiting time to make appointments with specialists and schedule exams through the Brazilian Unified Health System. As for satisfaction, the main complaint of the elderly participants refers to issues involving, above all, health management and work process, such as delay in making health care appointments, although most participants reported being satisfied with the care provided by health professionals. It is worth noting that learning about the conditions of access to health services used by elderly people living in rural areas and their satisfaction contributes to the planning, implementation, development and evaluation of public health actions, programs and policies.

Published: August 2020

The aim of the study was to investigate the association between different anthropometric indicators and high blood pressure in adults with obesity.This is a cross-sectional study with a non-probabilistic sample of adults with obesity. Systolic and diastolic blood pressure were measured using automated equipment (OMRON, model 742 HEM). The anthropometric indicators used were body mass index (BMI), relative fat mass (RFM), waist circumference (WC), waist-to-stature ratio (WSR) and waist-hip ratio (WHR). The data were analyzed by crude and adjusted (sex and age) linear regression, adopting a level of significance p <0.05. Among the 63 adults with obesity evaluated (38 woman; 35.27±7.02 years; BMI: 33.46±2.89 kg m-2; RFM: 39.98±6.70; WC: 109.38±10.15 cm; WSR: 0.64±0.05; WHR: 0.93±0.01), it was observed that the increase in systolic blood pressure was directly associated with the indicators RFM (p=0.011; Cohen’s F²= 0.42), WC (p=0.003; Cohen’s F²= 0.49), WSR (p=0.010; Cohen’s F²= 0.42) e WHR (p=0.001; Cohen’s F²= 0.52), but not to BMI (p=0.100). The elevation of diastolic blood pressure was directly associated with all the anthropometric indicators analyzed: BMI (p=0.040; Cohen’s F²= 0.14), RFM (p= 0.006; Cohen’s F²= 0.21), WC (p=0.002; Cohen’s F²= 0.26),WSR (p=0.004 Cohen’s F²=0.23) and WHR (p=0.012; Cohen’s F²=0.19). It was concluded blood pressure elevation was directly associated with the anthropometric indicators investigated and, among them, the WHR and the WC presented the best predictive capacity for systolic blood pressure and diastolic blood pressure elevations, respectively

Published: August 2020

Concerning the specificities of a longitudinal study, the trajectories of a subject's mean responses not always present a linear behavior, which calls for tools that take into account the non-linearity of individual trajectories and that describe them towards associating possible random effects with each individual. Generalized additive mixed models (GAMMs) have come to solve this problem, since, in this class of models, it is possible to assign specific random effects to individuals, in addition to rewriting the linear term by summing unknown smooth functions, not parametrically specified, then using the P-splines smoothing technique. Thus, this article aims to introduce this methodology applied to a dataset referring to an experiment involving 57 Swiss mice infected by Trypanosoma cruzi, which had their weights monitored for 12 weeks. The analyses showed significant differences in the weight trajectory of the individuals by treatment group; besides, the assumptions required to validate the model were met. Therefore, it is possible to conclude that this methodology is satisfactory in modeling data of longitudinal sort, because, with this approach, in addition to the possibility of including fixed and random effects, these models allow adding complex correlation structures to residuals.

Published: August 2020

The abrupt interruption of ethanol consumption increases anxiety-like behaviors in rodents and may reflect different aspects of ethanol dependence in humans. Measuring emotional behaviors resulting from ethanol withdrawal may aid in testing potential pharmacological agents for the treatment of ethanol dependence. In the present study, we used forced expositon to ethanol 20% during 10 days to mice, followed by abrupt withdrawal of the substance. The animals were evaluated 7, 24 and 35 h after ethanol withdrawal in three different behavioral paradigms, i.e., the open field (OF), light dark (LD) transition and elevated plus maze (EPM), tests usually used to measure anxiety-like behaviors. This was done with the aim of identifying the best interval as well as the most appropriate behavioral test to detect the effects of drugs that can relieve anxiety induced by ethanol withdrawal in mice. We also evaluated the effect of cannabidiol (CBD 10, 30 and 60 mg/kg) in ethanol withdrawn mice because it has been shown to alliviate drug addicton and present anti-anxiety effects. Our results show significant behavioral changes at 24 h following ethanol withdrawal. Diazepam (4 mg/kg), used as a positive control, counteracted the effects of ethanol withdrawal in OF, LD box and EPM. Cannabidiol attenuated anxiety-like behavior produced at 24 h after abstinence from ethanol exposure only in the EPM test.
Pentecostais na Política Brasileira na era da Constituinte de 1988 e alguns de seus desdobramentos
Authors: Pereira da Rosa Wanderley
Published: August 2020

O artigo descreve a relação entre os pentecostais e a política no Brasil, no período da Constituinte de 1988 e alguns desdobramentos nos anos seguintes. Há um período relativamente curto, que abarca a primeira metade do século XX até o início da década de 1960, marcado por um protestantismo progressista, preocupado com sua contextualização e com a construção cristã de uma ética política e social para o país. A inquietação intelectual e o esforço por uma participação ecumênica relevante à sociedade, que fosse capaz de suscitar uma reforma na religião brasileira, fez com que esse período se tornasse extremamente fecundo. Entretanto, nos anos que se seguiram, o protestantismo se fragmentou numa miríade de denominações, a maioria das quais preocupadas com seus próprios projetos de consolidação institucional, marcadas por uma espiritualidade individualista, moralista e interiorizada. Afastando-se daquela utopia inicial, os movimentos evangélicos, fruto dessa fragmentação, têm se preocupado cada vez mais com sua participação na política, mas, ao modo de um fisiologismo e nepotismo, bem como de um descaso para com a ética e os interesses republicanos. Este artigo foca, especialmente, na relação de líderes e denominações pentecostais e a política no Brasil no período supracitado. A história desta relação nos revela, finalmente, que as principais expressões do cristianismo — todas indelevelmente afetadas por um conservadorismo, sobretudo moral — não são nem melhores, nem piores do que a sociedade no interior da qual se constroem, mas, apenas um reflexo dela.
Pentecostalismo, catolicismo e bolsonarismo:
Authors: Valerio Samuel
Published: August 2020

Este artigo se propõe a detectar as pautas comuns entre os parlamentares evangélicos, católicos e o então candidato do Partido Social Liberal (PSL), Jair Messias Bolsonaro. Pode-se   perceber que existem agendas comuns aos parlamentares e o presidente eleito, algo que contribuiu para que pudesse chegar ao maior cargo do Poder Executivo da nação. Os candidatos evangélicos, sobretudo pentecostais, encontraram no discurso conservador e liberal de Bolsonaro elementos que os influenciaram a darem-lhe seus apoios. Tais pautas também foram assumidas por candidatos católicos que, ainda que tenham maior autonomia, encontraram em Bolsonaro uma fala que legitimava seu conservadorismo. Portanto, nosso texto procurará expor tais convergências e como foram importantes no apoio de pentecostais e católicos ao modo de fala, tipificando o fluxo eleitoral bolsonarista.

Published: August 2020

Zinc oxide-graphitic carbon nitride (ZnO/g-C3N4) composites were synthesized by precipitation method in order to improve photocatalytic activity under visible light. To enhance antimicrobial activity, silver was added into zinc oxide-graphitic carbon nitride (Ag/ZnO/g-C3N4). Ultrastructures of the composite were analyzed by X-ray diffractometry (XRD) and transmission electron microscopy (TEM). Photocatalytic activity of the composites was carried out by degradation of methylene blue solution as a function of contact time. The results revealed that ZnO/g-C3N4 was capable of dye degradation at 96.65%. Addition of Ag into ZnO/g-C3N4 resulted in increase of dye reduction rate. For antibacterial test, Ag/ZnO/g-C3N4 exhibited bactericidal activity against Pseudomonas aeruginosa and Bacillus cereus. For antifungal test, Ag/ZnO/g-C3N4 showed resistance to Aspergillusniger for 7 days. Ag/ZnO-g-C3N4 composite exhibited better photocatalytic and antimicrobial activities compare to ZnO and g-C3N4. These results indicate that precipitation method is a cheap, rapid and efficient method that can be used to synthesize Ag/ZnO-g-C3N4 composites. For further studies, applications of this Ag/ZnO-g-C3N4 composites in microbiological and agricultural fields will be carried out.

Published: August 2020

Synthesis of ceramic nanofibers is commonly carried out through electrospinning method. However, with the emergence of solution blow spinning (SBS) technology, spinning of nanofiber and its composites has resulted in a more straightforward and commercially scalable process. In this study, ceramic nanofibers (i.e., TiO2 nanofibers) were synthesized through SBS followed by calcination. Three critical parameters were investigated (i.e., precursor concentration, calcination temperature and time) to produce ready-to-use composite membranes and pure ceramic nanofibers. Characterizations of ceramic membranes and pure nanofibers include scanning electron microscope (SEM) analysis and energy dispersive x-ray (EDX) for elemental component analysis. Insights on the transformation of composite membranes into pure ceramic nanofibers and the role of calcination are also discussed.

In this study, durian seed was used to mix with poly (lactic acid), PLA for bioplates production. Durian seeds were prepared to peel off the brown skin on durian seed and then were dried. It was called brown skin durian (BSD). BSD was reduced the size below 1 mm. The mixtures between BSD and PLA were varied at 10:90, 20:80, 30:70 g/g. All mixtures were compressed into bioplates mold with varying the temperature at 90, 110, and 130 °C and the pressure at 2.0, 2.7, and 3.4 MN/m2. Bioplates sample were also investigated the properties in term of water absorption, tensile strength, and degradation. Results showed that the optimal mixture between BSD and PLA was 30:70 g/g and the suitable production condition presented the temperature and pressure at 130 °C and 3.4 MN/m2, respectively. These conditions provided low water absorption, high tensile strength and provided the proper degradation within 7 days. Hence, agricultural waste (durian seed) can be combined with PLA to produce the bio-container as bioplates which presented the potential to use in waste management.

Interlocking Brick System (IBs) is one of the current technologies used in the construction of load bearing walls. The concepts behind the IBs include the elimination of the mortar layer. The interlocking brick system investigated in this study is load bearing interlocking brick beam system relied on U-shaped hollow bricks in bed row to form beam to transfer load from wall opening. Reinforced concrete grout stiffeners were added in vertical and horizontal directions to enhance the stability and integrity of the beams. Mortar and grout are used as infill material. Generally, in this research, specimens are prepared for full scale testing with different parameters in reinforcement and fillings. The size of interlocking brick is 125 mm x 250 mm x 100 mm and the diameter of reinforcement bar (rebar) used is 12 mm. The dimension of the interlocking bricks beam is 2130 mm length, 125 mm width, and 300 mm height. The arrangement of hollow interlocking brick in bed row will causes a ductile behavior which will be mitigated by the horizontal reinforcement coated by mortar or grout between two layers of hollow brick.

The objective of this research was to study the clay tile (CT) production using palm ash (PA), spent bleaching earth (SBE) and palm fiber (PF) as substitute materials. The effect of ingredients and PF length on CT qualities were investigated. The ingredient of clay : PA : SBE : PF used three proportions as following 58 : 20 : 20 : 2, 56 : 20 : 20 : 4, and 54 : 20 : 20 : 6 (% by weight, wt). Each ingredient used the fiber length of 15 mm and 25 mm. The crystalline phase of raw materials was inspected. The CT after production were examined qualities as accorded with Thai industrial standard (TIS) in terms of water absorption, bulk density, acid corrosion and transverse breaking strength (TBS). Results showed that the clay tile qualities in terms of bulk density and acid corrosion were in the acceptable level as 1.45-1.65 g/cm3 and less than 0.03%, respectively. The water absorption quality was more than 6.5% meanwhile the TBS was below 600 N. Both later criteria were not pass the TIS standard, but it should be improved for further study. Hence, this research also revealed that the all wastes (PA, SBE, PF) from palm oil industry can be used to produce the clay tile.

This paper’s aim is to develop the tribological repair method in PEEK (Poly-ether-ether-ketone) polymer mechanical parts with surface damage. The radial rolling sliding contact tests were carried out by using a machined PEEK shaft with an artificial defect as surface damage. An alumina ball and a PTFE composite pin contacted a PEEK shaft specimen under cyclic compressive stress with friction. The particle as solid lubricant from a PTFE composite pin filled up the crevice of the artificial defect. After that, the artificial defect was covered with the deformed microgrooves on the PEEK shaft surface. Due to adhesion by compressive stress and friction, the crevice of the artificial defect was closed. In a running-in process, the artificial defect could be reduced by the adhesion repair.

Undoped ZnO and Ag-doped ZnO were prepared to use as near-infrared (NIR) shielding by simple precipitation method with zinc acetate and zinc nitrate as Zn precursor and silver nitrate as Ag precursor. The Ag-doped ZnO and undoped ZnO were characterized by XRD, SEM, and UV-vis-NIR spectrophotometer. The NIR reflectance performance reveals that Ag-doping improves the NIR shielding and optical property of pure ZnO. The 10 mol% Ag loading shows the lowest reflection in the visible region of about 15% and the highest reflection in the NIR region of about 50%. It not only shows the best NIR reflection but also exhibits the best thermal insulation. It reduces the inner temperature of the in-lab setup to mimic a house by 7.5°C when compared to the uncoated glass window. It is concluded that 10 mol% Ag-doped ZnO nanoparticles can result in UV-NIR shielding coatings.

Cement is the most utilized construction material. The energy-intensive processes that are involved in its production contribute up to 10% of total global CO2 emissions, with potentially adverse environmental implications. It is however possible, that energy and cost efficiency can be achieved by reducing on the amount of clinker, and in its place utilising supplementary cementitious materials (SCMs) or pozzolans that require less process heating and emit fewer levels of CO2. Currently, most sustainable concrete uses either GGBS (slag) or PFA (fly ash) to reduce the quantity of cement used in construction and highways applications. GGBS and PFA come from industries (steel and coal waste respectively) which are in decline that should not be relied upon in the long term. This report shows that cement in concrete can also be replaced with rice husk ash (RHA) which actually enhances the mechanical properties. RHA comes from the food production industry and is vital for the growing global population. It is thus a socially responsible objective to use a pozzolan in civil engineering applications that is sourced from an environmentally friendly and sustainable industry. This study investigated the potential of RHA to be used as a SCM by evaluating mechanical properties. Experiments were carried out by supplementing cement in concrete mixes with RHA at up to 10% replacement by mass. Results were compared with a control specimen (100% cement), with a water/binder (w/b) ratio of 0.4 and C32/40 design mix using CEM I. The results show excellent early age strengths with all RHA mixes surpassing 40 MPa strength within 7 days which is contrary to general trends in SCM concrete where strength development is slow in the initial stages in comparsion to 100% cement concrete. All RHA specimens exhibited impressive flexural and tensile strengths.

Introduction: Water pollution is a one of the public health burdens and the consumption of contaminated water has adverse health effects and even affects fetal development. The objective was to describe the household water usage pattern, community awareness of water pollution and factors associated with it among adult residents in MOH area, Uduvil. Method: A descriptive cross-sectional study was conducted on a community-based sample of 817 adult residents with multi stage cluster sampling method. The data was collected by an int erviewer adm inistered questi onnaire. Statistically significance for selected factors and awareness were analyzed with chi square and Mann-Whitney U test. Results: This study sample consisted of 85% (n=695) female, mean age of 47.8±16.2. Majority 97.5% (n=797) of the participants knew about the water pollution in their area. Only 23% (n=188) participants knew about all the characters of good water. Among the participants 48.6% (n=397) had noticed the organoleptic changes in their own well and only 1.5% (n=12) had confirmed the pollution by lab test. Among them 71.2% (n=582) were treating the water and 24.9% were boiling the water. The median knowledge score was 10.93. There is significant difference in knowledge related to water pollution among different educational levels (U=53339.5, p<0.001) and the presence of water related diseases in the family (U=54146.5, P<0.01). There was a significant association with the age groups and their water treatment practices (χ2= 7.17, P<0.01), the presence of under 5-year age child in the family had significant association with water treatment practices (χ2=13.1, P<0.001).

Published: August 2020

Context

Accreditation competencies have been updated to include interprofessional education (IPE) as a required focus for health care students. While the development and implementation of IPE learning activities have been documented in other professions, there is a dearth of information describing didactic integration of IPE within athletic training program curricula.

Objective

To ascertain how IPE is being integrated within the didactic curriculum of athletic training programs.

Design

Consensual qualitative approach.

Setting

Higher education institutions with accredited professional master's athletic training programs.

Patients or Other Participants

Seventeen program faculty (9 women, 8 men; 1 program director, 14 clinical education coordinators, 2 other program faculty) shared their perspectives on integrating IPE.

Data Collection and Analysis

Semistructured phone interviews were used. All interviews were digitally recorded and transcribed. Upon achievement of data saturation, a consensual qualitative analysis approach was employed to determine themes. Data trustworthiness was achieved through triangulation, member checking, and use of an external auditor.

Results

More than half of the programs represented in this study (11 of 17) report that IPE activities are a required component of their didactic curriculum. Themes for integration of IPE include delivery methods, educational content and objectives, assessment, and logistics. Sample IPE activities include case-based discussions, dedicated IPE courses, online modules, and simulation.

Conclusions

Integration of IPE into the curriculum requires logistical considerations such as determining which health care disciplines to include, resources available (time, space, personnel), as well as overall institutional support. Program faculty in our study described varied methods to deliver IPE learning activities that meet content goals and objectives. Prior to integrating IPE into an athletic training curriculum, program faculty should determine the method of delivery and what content will work to achieve the goals of relevant stakeholders. Consideration of these components for didactic integration should work to create cohesive and meaningful learning experiences.

No que diz respeito ao ensino da Matemática, o uso de diferentes tipos de raciocínio é relevante para que o aluno tenha um panorama completo de como a Matemática é construída. Neste artigo compartilhamos resultados de uma pesquisa cujo objetivo foi compreender se, e de que modo, diferentes tipos de raciocínio – dedutivo, indutivo, abdutivo e analógico – se fazem presentes nos capítulos de Geometria de 21 Livros Didáticos de Matemática do Ensino Médio, aprovados pelo Programa Nacional do Livro e do Material Didático (PNLD) de 2018. Assumimos uma abordagem qualitativa de cunho documental e, como referencial teórico, utilizamos as ideias de raciocínio propostas por David Reid e Christine Knipping. As conclusões indicaram que nem todos os livros apresentam os quatro tipos de raciocínio e que há uma maior abordagem dedutiva e indutiva, em detrimento dos outros tipos. Concluímos, também, que nenhuma coleção analisada propõe uma conexão entre os diferentes raciocínios, assim como não defendem a importância de seus usos.
