Authors: Štulajterová R. , Medvecký L. , Giretová M. , Sopčák T. , Briančin J.
Published: August 2020

The tetracalcium phosphate/nanomonetite (TTCPMH) biocements with the addition of sodium alginate were prepared by mechanical homogenization of powder mixture with hardening liquid containing sodium alginate. The effect of various viscosity of different alginates on properties of TTCPMH cement mixture was investigated. The medium viscous (MED) alginate had a more negative effect on setting process and compressive strength than low viscous (LOW) alginate. An approx. 50% decrease in mechanical properties (compressive strengths, Young´s modulus, work of fracture (WOF)) was revealed after an addition of 0.25 wt % with rapid fall above 1 wt % of LOW alginate in biocement. A statistically significant difference in the WOF was found between of 0.25 and 0.5 LOW alginate biocements (p<0.035) whereas no statistical differences were revealed between WOF of 0.5 and 1 LOW alginate biocements (p˃0.357). In the microstructure of composite cements, the increased amounts of granular or finer needle-like nanohydroxyapatite particles arranged into the form of more separated spherical agglomerates were observed. A low cytotoxicity of cement extracts based on measurement of cell proliferation was revealed.

Published: August 2020

Fused Layer Modelling (FLM) is one out of several material extrusion (ME) additive manufacturing (AM) methods. FLM usually deals with processing of polymeric materials but can also be used to process metal-filled polymeric systems to produce metallic parts. Using FLM for this purpose helps to save costs since the FLM hardware is cheap compared to e.g. direct metal laser processing hardware, and FLM offers an alternative route to the production of metallic components.

To produce metallic parts by FLM, the methodology is different from direct metal processing technologies, and several processing steps are required: First, filaments consisting of a special polymer-metal composition are produced. The filament is then transformed into shaped parts by using FLM process technology. Subsequently the polymeric binder is removed (”debinding”) and finally the metallic powder body is sintered. Depending on the metal powder used, the binder composition, the FLM production parameters and also the debinding and sintering processes must be carefully adapted and optimized.

The focal points of this study are as following:

1. To confirm that metallic parts can be produced by using FLM plus debinding and sintering as an alternative route to direct metal additive manufacturing.

2. Determination of process parameters, depending on the used metal powders (steel and copper) and optimization of each process step.

3. Comparison of the production paths for the different metal powders and their debinding and sintering behavior as well as the final properties of the produced parts.

The results showed that both materials were printable after adjusting the FLM parameters, metallic parts being produced for both metal powder systems. The production method and the sintering process worked out well for both powders. However there are specific challenges in the sintering process that have to be overcome to produce high quality metal parts. This study serves as a fundamental basis for understanding when it comes to the processing of steel and copper powder into metallic parts using FLM processing technology.

Authors: Singh Palwinder , Singh Lakhvir , Singh Sehijpal
Published: August 2020

The customary edged tool for machining is uneconomical for harder and hard to machine materials and furthermore the level of surface finish accomplished is not that great. As of late, a lot of consideration in mechanical engineering has been centered on finishing tasks. Not many investigations have been accounted for till date on the advancement of substitute magnetic abrasive powder (MAP). In this paper, to improve the finishing performance, the abrasive powder were prepared by mechanical alloying of diamond powder and iron (Fe) powder, compacting these with universal testing machine (UTM) and then sintered at different temperature in a sintering machine in an inert gas (H2) atmosphere. These compacts were crushed and sieved to obtain various sizes of MAP. This abrasive powder were micro-structurally examined. The results indicate that the densification increases and porosity decreases with increasing temperature. Moreover, the prepared bonded MAP has potential performance as a new MAP for fine finishing in Magnetic Abrasive Flow Machining (MAFM) process.

Authors: Attias Anna , Ciavalini Simona , Morrone Carla , Saitta Daniela
Published: August 2020

This paper adapts an actuarial mathematical model, built for the Italian public pension system, based on the law proposal 3035/2009 to the Accountant Pension Fund (CNPADC). The aim is to introduce a new philosophy pension highly correlated with the concept of adequacy for an ambitious social welfare; using the logic of the 3035/2009 proposal, which guarantees a minimum threshold for the replacement rate of the direct pension, this study provides a rigorous actuarial mathematical model that explains a sort of rate of contribution at a tendential equilibrium, in a pay-as-you-go pension system. This model reveals for which parameters it is possible to intervene to maintain the standard of living in retirement.
A tradução do ritmo em Henri Meschonnic a partir da teoria de Émile Benveniste
Authors: Veshagem Marina Bento
Published: August 2020

Este trabalho apresenta o conceito de ritmo que embasa a teoria da tradução de Henri Meschonnic. O autor defende o ritmo na linguagem, diferente daquele visto como alternância regular entre tempos fortes e fracos, desvinculado da música e de uma métrica prévias. A definição que contribui para tal formulação de ritmo nasceu na redefinição etimológica do conceito feita por Émile Benveniste. Ele mostra como o ritmo tem em sua etimologia a forma, enquanto movimento no instante em que é tomado e, assim, ele pode tornar-se múltiplo. Dessa maneira, o ritmo poderá ser definido como a organização do sentido no discurso, que produz uma semântica própria, a significância. Renovada pelo programa do ritmo, a tradução, por sua vez, será entendida como uma maneira de agir sobre a linguagem.
Altered Expression of the m6A Methyltransferase METTL3 in Alzheimer’s Disease
Authors: Huang He , Camats-Perna Judith , Medeiros Rodrigo , Anggono Victor , Widagdo Jocelyn
Published: August 2020

Cognitive impairment in Alzheimer’s disease (AD) is associated with dysregulation of the RNA and protein expression profiles in the brain. Recent studies have highlighted the importance of RNA post-transcriptional regulation (epitranscriptomics) in higher order brain functions. Specifically,N6-methyladenosine (m6A), which controls RNA stability, splicing, translation and trafficking, plays an important role in learning and memory. This raises the question of whether m6A signaling is perturbed in AD. To address this, we investigated the expression profile of known m6A-regulatory genes using a public RNA-seq dataset and identified a subset of genes which were significantly dysregulated in the human AD brain. Among these, genes encoding the m6A methyltransferase,METTL3, and a member of the m6A methyltransferase complex (MACOM),RBM15B, were downregulated and upregulated in the hippocampus, respectively. These findings were validated at the protein level using an independent cohort of postmortem human brain samples. Unexpectedly, we observed an accumulation of methyltransferase-like 3 (METTL3), but not RBM15B, in the insoluble fractions, which positively correlated with the levels of insoluble Tau protein in the postmortem human AD samples. Aberrant expression and distribution of METTL3 in the hippocampus of the AD brain may therefore represent an epitranscriptomic mechanism underlying the altered gene expression patterns associated with disease pathogenesis.

Zottoli argued that the enthymeme theory was a very useful tool to understand Chinese texts. To show this, he analyzed and examined the Baguwen (八股文). The enthymematic features of it are compable to enthymemes of signs or enthymemes of wide-ranging opinions. They are considered to be makers of contexts that are accepted and approved largely by the audience according to common sense. They are also very similar to loci communes of Cicero.

Published: August 2020

Uma doença respiratória aguda causada por um vírus denominado de SARS-CoV-2 foi transmitido a um número expressivo da população mundial. Com a disseminação global, a Organização Mundial de Saúde decreta em março de 2020 como Pandemia, e o Brasil de imediato, começou a tomar as atitudes cabíveis como quarentena e isolamento social. Com este quadro, não restou senão, suspender as aulas no Estado do Rio Grande do Sul (RS), e para minimizar o impacto da falta de aulas, a rede privada de ensino decidiu dar continuidade ao calendário letivo de forma on-line e começou a operar com as plataformas digitais existentes para os ensinos Fundamental e Médio apesar que em algumas escolas já se utilizava a mesma. Este artigo tem como objetivo avaliar a capacidade de aprendizagem no Ensino de Química por meio de uma plataforma digital e o quanto os estudantes conseguem apreender os conteúdos via online sem a presença diária física de um tutor, flexibilizando a rotina diária de aula, tendo em vista que as aulas podem ser assistidas em horários diversos quando o aluno se veja impossibilitado de acompanhá-la no horário. A metodologia adotada foi o estudo descritivo exploratório com aplicação de um questionário como pesquisa qualitativa. Como resultado verificou-se que apesar dos estudantes terem indicado certa dificuldade para aprender Química, ainda assim obtiveram resultados positivos com a inserção do ensino remoto durante este período de pandemia, o que pode indicar que plataformas digitais são ferramentas com potencial para as escolas como complemento híbrido para futuros estudos.

Authors: Cigerci Ali E. , Genc Harun
Published: August 2020

Background and Study Aim: The target of this paper was to examine the effects of strength training with different frequency on physical, performance and strength features on untrained university male students.

Material and Methods: 24 subjects (age= 21.47+1.50) were divided into three groups; 8 for strength training group once a week (ST1), 8 for strength training group three times a week (ST3) and 8 for control group (CG). The training groups were applied a 6-week ST that lasted approximately 80-90 minutes for each training 3 days a week for ST3 and once a week for ST1. Analysis of intergroup, intragroup and the effect of training were carried out with repeated measures ANOVA. Significance was set at 0.05.

Results: There was no difference in body weight and body mass index values in training groups, while a significant increase was found in CG. In addition, there was a significant decrease in body fat percentage and a significant increase in skeleton muscle mass without any change in body weight and body mass index in ST3. No statistical difference was seen in 10-20 m sprint and agility tests in all groups. For vertical jump, balance test for right and left leg, there was a significant difference between the pre and post-test measurements of ST1 and ST3. In standing long jump measurements, significance was seen in favor of ST3. In strength parameter, while a significant difference was detected in bench press, shoulder press and push-up due to the development of training groups, a statistically significance was found in squat and biceps curl by reason of improvement in ST3.

Conclusion: As a conclusion, it can be said that 6-week strength training with different frequency applied on untrained male students has a positive effect on physical, performance and strength features.

This article was migrated. The article was marked as recommended. With the onset of the coronavirus-19 (COVID-19) pandemic, we transformed an in-person art museum-based course for medical students into an online format. This brought new challenges but offered unexpected advantages. The course included daily close-looking of artworks using the Visual Thinking Strategies method, group arts-based activities, reflective writing, and independent creating assignments. The virtual format allowed us to incorporate important features that were unavailable in our in-person elective: multi-media activities, access to nearly unlimited international works of art, and personal reflection from one's private space. As instructors, the experience enlightened us on the value of online arts-based teaching.
Molecular identification, characterization, and expression analysis of a serine protease inhibitor gene from cotton bollworm, Helicoverpa armigera (Lepidoptera: Noctuidae)
Authors: Shakeel Muhammad
Published: August 2020

Abstract Serine protease inhibitors (serpins), a superfamily of protease inhibitors, are known to be involved in several physiological processes, such as development, metamorphosis, and innate immunity. In our study, a full-length serpin cDNA, designated Haserpin1, was isolated from the cotton bollworm Helicoverpa armigera. The cDNA sequence of Haserpin1 is 1176 nt long, with an open reading frame encoding 391 amino acids; there is one exon and no intron. The predicted molecular weight of Haserpin1 is 43.53 kDa, with an isoelectric point of 4.98. InterProScan was employed for Haserpin1 functional characterization, which revealed that Haserpin1 contains highly conserved signature motifs, including a reactive center loop (RCL) with a hinge region (E341–N350), the serpin signature, (F367–F375) and a predicted P1–P1′ cleavage site (L357–S358), which are useful for identifying serpins. Transcripts of Haserpin1 were constitutively expressed in the fat body, suggesting that it is the major site for serpin synthesis. During the developmental stages, a fluctuation in the expression level of Haserpin1 was observed, with low expression detected at the 5th-instar larval stage. In contrast, relatively high expression was detected at the prepupal stage, suggesting that Haserpin1 might play a critical role at the H. armigera wandering stage. Although the detailed function of this serpin (Haserpin1) needs to be elucidated, our study provides a perspective for the functional investigation of serine protease inhibitor genes.

Published: August 2020

Abstract The genus Cyclocephala is common in Brazil (Coleoptera, Scarabaeidae, Dynastinae). The adults of some species are important pollinators, and the larvae develop in the soil, feed on organic matter, and contribute to nutrient cycle, but immatures of some species feed on plant roots, and some were registered causing damage in crops. The mating process of some phytophagous scarab beetles has a chemical recognition step, and the antenna is the main structure involved in the detection of odorants associated with insect communication. In the present study the mating behavior, life cycle, and antennal sensilla of C. putrida are described. The study was conducted at the Universidade Estadual de Mato Grosso do Sul, Cassilândia, Brazil. Adults were collected by a light trap installed from January 2016 to December 2017 and were taken to the laboratory for studies. Adults swarms are brief and were registered from January to February, and specimens were mostly collected at 20:00 to 22:00h. Chemical recognition may occur at least during one of the mating steps, during which the couple kept their antennae moving and the lamellae open, while females select males. In laboratory, the mating process lasted 7.5 minutes on average. The antennae of females have about 3399 sensilla and males about 4229 sensilla. Sensilla placodea types I, II, and III are the most abundant, and sensilla ampullacea, basiconica, and coeloconica are also present. The embryonic period lasted 16.0 days; first, second and third instars lasted 16.0, 48.3, and 165.3 days, respectively. The pupal period lasted 24.0 days. The period between egg deposition and adult emergency is about 271.5 days.

ABSTRACT Introduction The impact of the new coronavirus (SARS-COV-2) and its worldwide clinical manifestations (COVID-19) imposed specific regional recommendations for populations in need of specialized care, such as children and adolescents with kidney diseases, particularly in renal replacement therapies (RRT). We present the recommendations of the Brazilian Society of Nephrology regarding the treatment of pediatric patients with kidney diseases during the COVID-19 pandemic. Methods Articles and documents from medical societies and government agencies on specific recommendations for children on RRT in relation to COVID-19 as well as those focused on epidemiological aspects of this condition in Brazil Were evaluated and analyzed. Results We present recommendations on outpatient care, transportation to dialysis centers, peritoneal dialysis, hemodialysis, and kidney transplantation in children and adolescents during the COVID-19 pandemic in Brazil. Discussion Despite initial observations of higher mortality rates in specific age groups (the elderly) and with comorbidities (obese, diabetics, and those with cardiovascular diseases), patients with chronic kidney disease (CKD) on RRT are particularly prone to develop COVID-19. Specific measures must be taken to reduce the risk of contracting SARS-CoV-2 and developing COVID-19, especially during transport to dialysis facilities, as well as on arrival and in contact with other patients.

Published: August 2020

ABSTRACT Vascular accesses for hemodialysis are considered the patient’s lifeline and their maintenance is essential for treatment continuity. Following the example of institutions in other countries affected by the Covid-19 pandemic, the Brazilian Society of Nephrology developed these guidelines for healthcare services, elaborating on the importance of carrying out procedures for the preparation and preservation of vascular accesses. Creating definitive accesses for hemodialysis, grafts and arteriovenous fistulas are non-elective procedures, as well as the transition from the use of non-tunneled catheters to tunneled catheters, which cause less morbidity. In the case of patients with suspected or confirmed coronavirus infection, one may postpone the procedures for the quarantine period, to avoid spreading the disease.

A judicialização da saúde no Brasil e na Colômbia: uma discussão à luz do novo constitucionalismo latino-americano
Authors: d’Ávila Luciana Souza , Andrade Eli Iola Gurgel , Aith Fernando Mussa Abujamra
Published: August 2020

Resumo Este artigo busca analisar a judicialização da saúde no Brasil e na Colômbia à luz do novo constitucionalismo latino-americano (NCLA), corrente conceitual adotada na região que rompe com os modelos constitucionais europeus e norte-americanos clássicos. No Brasil, a Constituição de 1988 veio em resposta a um longo período de governos militares e, na Colômbia, a Constituição de 1991 surgiu em um contexto de abusos de direitos humanos e altos níveis de violência. O NCLA se materializa a partir dessas novas Cartas Políticas e se sustenta no incremento das formas de participação e na ampliação do papel do Judiciário e dos direitos, como o da saúde. Entretanto, as constituições que trazem uma ampla carta de direitos não conseguiram enfrentar as políticas orientadas para o mercado e a privatização dos serviços de saúde, colocando em xeque a efetivação do direito à saúde e levando ao aumento das ações judiciais. Nesse cenário emerge o protagonismo do Judiciário, fortalecido pelas novas constituições, como poder estatal capaz de concretizar um direito previsto, mas marginalizado. A identificação das necessidades de saúde e reivindicações de segmentos sociais apresenta-se como princípio basilar nesse processo e sinaliza o resgate do NCLA para a efetivação do direito à saúde por meio do litígio estrutural.
The Body Speaks Before It Even Talks: Deliberation, Populism and Bodily Representation
Authors: Casullo Maria Esperanza
Published: August 2020

Deliberation is a complex interpersonal process that involves different forms of communication. While earlier versions of deliberative theory had overly rationalistic and proceduralist views of linguistic exchange, it is now understood that deliberation involves a full range of speech cultures, which include humour, storytelling, metaphors, testimonies and others, as well as the full range of emotions including fear, anger, compassion and sympathy. This article extends these developments in deliberative scholarship by placing the role of the body as central to the practice of public deliberation. The agents of real-world deliberations are not pure consciousness but embodied beings whose corporeality carries the palimpsest of marks of their class, age, ethnicity and sexual orientation, amongst others. Bodily self-presentation informs how affect, identification and political representation are established even before words are spoken. The goal of this article is to reflect on the effect of bodily identification and representation on the process of deliberation. Drawing on populism literature, particularly the socio-cultural approach, I explore four types of bodily representation: popular, technocratic, authoritarian and populist, and the affects they might provoke in other participants in deliberations, both negative and positive. Through this article, I hope to demonstrate how the vocabulary of populism research can equip deliberative democrats to identify, confront and negotiate the politics of bodily representation.

In this inaugural issue of the Journal of Deliberative Democracy, we are pleased to present reviews of five recently published books that will shape the scholarship on public deliberation in the years to come. These books engage with key theoretical and methodological debates in the field, contribute to the way we understand deliberation in relation to other political practices, and present compelling empirical accounts of how deliberative democracy comes alive in contemporary times.The reviewed titles are Mapping and Measuring Deliberation by André Bächtiger and John Parkinson (2019); Demagoguery and Democracy (2017) by Patricia Roberts-Miller Re-imagining Democracy by Jane Suiter and David Farrell (2019); Oral Democracy by Paromita Sanyal and Vijayendra Rao (2018) and Beyond Liberalism by Michael Briand (2019, Praeger).
Rethinking Representation and Diversity in Deliberative Minipublics
Authors: Steel Daniel , Bolduc Naseeb , Jenei Kristina , Burgess Michael
Published: August 2020

Deliberative minipublics often seek to recruit participants who are representative and diverse. This raises theoretical and practical challenges, because representativeness and diversity can be interpreted in multiple ways and can conflict with one another. We address this issue by proposing a purposive design approach, according to which the appropriate conceptualisations of representativeness and diversity, and thereby recruitment strategies, depend on the deliberative mini-public’s aims. We argue that deliberative minipublics frequently have mixed aims, which can justify hybrid recruitment strategies that reflect distinct senses of representativeness or diversity.

This article describes the origins and development of the federal funds market from its inception in the 1920s to the early 1950s. We present a newly digitized daily data series on the federal funds rate from April 1928 through June 1954. We compare the behavior of the funds rate with other money market interest rates and the Federal Reserve discount rate. Our federal funds rate series will enhance the ability of researchers to study an eventful period in U.S. financial history and to better understand how monetary policy was transmitted to banking and financial markets. For the 1920s and 1930s, our series is the best available measure of the overnight risk-free interest rate, better than the call money rate which many studies have used for that purpose. For the 1940s-1950s, our series provides new information about the transition away from wartime interest-rate pegs culminating in the 1951 Treasury-Federal Reserve Accord.

Transarterial chemoembolization (TACE) is currently the recommended treatment for hepatocellular carcinoma (HCC). However, long-term chemoembolization triggers the inflammatory response and may lead to postembolization syndrome (PES). Although several types of degradable microspheres have been developed to reduce drug toxicity and PES incidence, the clinical outcomes remain unsatisfactory. Previously, we have developed a new type of spherical, calibrated, biodegradable, radiopaque microspheres (SCBRM) and demonstrated their safety and efficacy in a pig model. Thus, the goal of this feasibility study was to determine the clinical safety and efficacy of the new SCBRM in intermediate-stage HCC patients. In this study, 12 intermediate-stage HCC patients underwent TACE using SCBRM with a calibrated size of 100–250 μm. The disease control rates at 1 month and 3 months after TACE-SCBRM treatment were 100% and 75.0%, respectively. The objective response rates at 1 month and 3 months after treatment were 66.7% and 58.3%, respectively. Very few adverse events were observed with one patient developing nausea. One day after the treatment, alanine aminotransferase, alanine aminotransferase, and total bilirubin levels were slightly elevated in the patients, but all returned to baseline on day 7. The median and mean overall survival times were 33 months (interquartile range, 12.8–42.0) and 29.2 ± 14.3 months, respectively. The 1-year and 2-year survival rates were 91.7% and 58.3%, respectively. In conclusion, TACE with the new SCBRM microspheres is clinically safe and effective, and it represents a promising approach in the management of intermediate-stage HCC.

Şanlıurfa ili sınırları içerisinde son yıllarda yapılan araştırmalar, Çanak Çömleksiz Neolitik döneme tarihlenen merkezler arasındaki bağlantıların sanılandan daha yoğun olduğunu ortaya çıkartmıştır. Özellikle, M.Ö. 9. binyılın başlarında ortaya çıkan bu yoğunluk, benzer özellikteki merkezlerin sayıca artması ile kendini göstermektedir. Bu merkezler; Sefer Tepe, Kurt Tepesi, Hamzan Tepe, Taşlı Tepe, Karahan Tepe ve Harbetsuvan Tepesi’dir ve özellikle “T” şeklinde dikilitaşlar ile karakterize edilmektedir. Göbekli Tepe’nin II. tabakasında görülen “T” şeklinde dikilitaşlarla aynı boyutta dikilitaşların bulunduğu bu merkezler içerisinde, 2017 yılında Şanlıurfa Müzesi ile birlikte Harbetsuvan Tepesi’nde arkeolojik kazılara başlanmıştır. Daha çok kaçak kazı alanlarının yaratmış olduğu tahribatın boyutunu anlamak için yapılmış olan bu kurtarma kazısında, yeni mimari bulgular ve arkeolojik buluntular ortaya çıkartılmıştır. Harbetsuvan Tepesi’nde yapılan kazılarda ortaya çıkartılan dörtgen planlı yapıların ortasında ya da duvarların içerisinde bulunan dikilitaşların varlığı Göbekli Tepe’nin II. tabaka yapıları ile benzer olduğunu ortaya koymuştur. Ele geçen diğer eserlere bakıldığında; falluslu heykel parçası, kol ve parmak kabartmalı dikilitaş, Byblos uçları, yassı baltalar, obsidyen okucu, bazalt taşından havanelleri ve taş kurnalar gibi bu döneme özgü buluntular söz konusudur. Dolayısıyla Harbetsuvan Tepesi kazıları, Göbekli Tepe dışında ikinci bir kült merkezi özelliği taşıyan yeni bir merkezin de var olduğunu kesin bir şekilde ortaya koymuştur. Bu çalışmada, Harbetsuvan Tepesinin yer aldığı Tek Tek Dağları bölgesinin Neolitik dönemde günümüzde olduğu gibi bitki örtüsü yönünden zengin olmadığı, buna bağlı olarak da Neolitik dönem yapı mimarisinin buna göre şekillendiğini göstermeye çalışacağız. Ayrıca, 2018 yılında Harbetsuvan Tepesi kazısında açığa çıkan mimari yenilikler ve küçük buluntular üzerine bir değerlendirme yapılacaktır.

Bubble strip aqueous gas sampling v4
Authors: B Nothaft Daniel
Published: August 2020

The "bubble strip" method has been shown to be an effective means for sampling a gas phase in equilibrium with water (Kampbell et al., 1998). Here, a method optimized for sampling large quantities of equilibrated gas (~60 mL) is demonstrated. This has applications for advanced isotopic analyses, which often require large sample sizes. This version was used in Samail Ophiolite sampling in 2019. Kampbell D. H., Wilson J. T., Mcinnes D. M.

To the Issue of Communicative Teaching Foreign Languages
Authors: Murashkina O.V.
Published: August 2020

The article deals with the issue of teaching foreign languages with the usage of methods communicative. Communicative approach and communicative method are two interrelated concepts. Language competence developed in social context is the basis for successful communication in the target language. The article deals with the problem of the formation of phonological hearing in the process of teaching Spanish as a foreign language. The problem of learning the correct pronunciation is key in learning Spanish at the initial stage due to the diverse dialectal variability of the Spanish language. The main difficulty in mastering Spanish phonetics is the variety of national variants and dialects, which at the level of sounding speech represent a motley allophonic picture. In this regard, the task of forming phonological hearing in the process of teaching Spanish as a foreign language is a priority. The difference between phonetic systems and phonological structures of the native and the studied foreign languages is the main reason for linguistic interferences, therefore it is important to determine the allophonic picture when teaching the phonetics of the Spanish language.

Background: The trans-theoretical model is a model that is very sensitive to changes in the minor progress of behavior. Therefore, the trans-theoretical model is more practical than other patterns of behavior change, which have been considered all or no to measure physical activity. This study aimed to standardize and determine the validity and reliability of the tensile movement questionnaire at the University of Medical Sciences employees.
methods: In this study, after searching the texts and the study of the same questionnaires and tools and among the available and related tools, the initial questionnaire was designed. First, the validity and content of the questionnaire were measured using experts' comments. Then, the ability to understand the questionnaire based on the opinions of 10 employees was investigated. Finally, to determine the reliability with the experimental-open test method, 30 employees, Cronbach's alpha, and the correlation coefficient were obtained using SPSS software.
Results: After performing the necessary reforms with experts' opinions, finally, the questionnaire with increasing the number of questions of the field of self-efficacy from 6 to 7 questions, the reduction of the number of questions of the interests of stretching movements from 10 to 5 questions, increasing the number of questions of the barriers of stretching movements from 4 to 7 questions and increasing the number of questions of In the validation stage, each 40 of the questions had acceptable content validity (8.0 to 99.0). Also, at least 80% of the questions were diagnosed in terms of the target group acceptable. Cronbach's alpha coefficient and correlation coefficient were 86.0 and 7.0, respectively.
Conclusion: A designed questionnaire based on the trans-theoretical model constructs to assess educational intervention to enhance the tensile movements of employees has acceptable reliability and validity.
