Published: July 2020

Although many approaches have been proposed to manipulate propagating waves (PWs) and surface waves (SWs), usually each operation needs a separate meta-device, being unfavorable for optical integrations. Here, we propose a scheme to design a single meta-device that can efficiently generate SWs and/or PWs with pre-designed wavefronts, under the excitations of circularly polarized (CP) PWs with different helicity. As a proof of concept, we design and fabricate a microwave meta-device and experimentally demonstrate that it can convert incident CP waves of opposite helicity to SWs possessing different wavefronts and traveling to opposite directions, both exhibiting very high efficiencies. We further generalize our scheme to design a meta-device and numerically demonstrate that it can either excite a SW beam with tailored wavefront or generate a far-field PW with pre-designed wavefront, as shined by CP waves with different helicity. Our work opens the door to achieving simultaneous controls on far- and near-field electromagnetic environments based on a single ultra-compact platform.

Published: July 2020

Although the first lasers invented operated in the visible, the first on-chip devices were optimized for near-infrared (IR) performance driven by demand in telecommunications. However, as the applications of integrated photonics has broadened, the wavelength demand has as well, and we are now returning to the visible (Vis) and pushing into the ultraviolet (UV). This shift has required innovations in device design and in materials as well as leveraging nonlinear behavior to reach these wavelengths. This review discusses the key nonlinear phenomena that can be used as well as presents several emerging material systems and devices that have reached the UV–Vis wavelength range.
Ultra-thin curved visible microdisk lasers with three-dimensional whispering gallery modes
Authors: Zhou Taojie , Ng Kar Wei , Sun Xiankai , Zhang Zhaoyu
Published: July 2020

Microdisk lasers are important components in photonic integrated circuits (PICs), of which the whispering gallery modes (WGMs) are usually confined within a two-dimensional (2D) planar slab. Here, owing to the strain relaxation of quantum wells by wet-etching method, we present ultra-thin curved visible microdisk lasers with single-mode lasing emission and a high quality factor of ∼17,000, which enable a 3D spatial intensity distribution of WGMs and provide an extra degree of freedom for the confined photons compared with the conventional 2D in-plane WGMs. The curved microdisk lasers with a 3D spatial profile of WGMs may provide attractive applications in flexible and multilevel photon sources for the PICs.
Undrained Responses of Partially Saturated Sand Induced by Biogas under Dynamic Cyclic Loading
Authors: Peng Erxing , Sheng Yu , Hu Xiaoying , Zhang Dingwen
Published: July 2020

Desaturation denotes a methodology used to mitigate sand liquefaction. Signifying a new form of material, biogas is deemed more feasible for the purpose of desaturation. The present study entailed the adoption of a microbial denitrification process for generating nitrogen gas to induce specimens that are partially saturated. These specimens were utilized for the consolidated undrained triaxial tests performed isotropically. Based on a simplified process concerning the evaluation of liquefaction, the study provided the crucial degree of saturation for determining its minimum degree for averting liquefaction under varying intensities of earthquake. According to test findings, the soils’ liquification resistance grows with an increase in the saturation degree. The number of loading cycles used for initializing liquefaction increases to 34 cycles from 18 cycles under undrained asymmetricity as the extent of saturation reduces to 95.9 % from 100 % when the similarity of stress ratio is observed. Furthermore, the ratio of liquification resistance goes up in a linear pattern initially as the degree of saturation decreases. Meanwhile the ratio declines as the relationship becomes increasingly nonlinear. As a result, there is a gradual reduction in liquefaction resistance as the magnitude of earthquake rises, with a decline in the critical saturation degree. Notably, the extent of this decline is predicated on the relative density.

Pescadores e comerciantes de peixes na região da baixada cuiabanadesenvolvem diversas estratégias para dificultar a produção de provas de pesca predatória no Estado de Mato Grosso, em especial para o pescado das espécies:  Cachara (Pseudoplatystoma fasciatum)e Pintado (Pseudoplatystoma corruscans).Estas duas espécies, agrupam qualidades inéditas do ponto de vista gastronômica epor essa razão, possuem grande lucratividade. Como a lei Estadual 9096 de 16 de janeiro de 2009 proíbe a captura de pescado através de diversos tipos de petrechos, em especial os específicos do artigo 25, item “V” letra “f” que trata sobre os petrechos de malha (rede e tarrafão), os contraventores escolhem a extração das cabeças dos animais no intuito de polemizar o método da captura e ainda o tamanho do pescado. Este estabelece um modelo estatístico para estas espécies de forma a reconstituir o tamanho do pescado apreendido mesmo sem a cabeça, viabilizando a estimativa pericial.
Impacto de la musicoterapia en la calidad de vida de personas con discapacidad intelectual: una revisión de la literatura
Authors: García García Beatriz , Rubio Belmonte César
Published: July 2020

La musicoterapia es una modalidad de intervención ampliamente utilizada en el ámbito de la discapacidad intelectual. Los resultados personales de las intervenciones que suponen una mejora en la calidad de vida son considerados, a día de hoy, como un indicador de buenas prácticas en este ámbito. El objetivo del presente trabajo es relacionar los resultados de intervenciones de musicoterapia en personas con discapacidad intelectual con las dimensiones del modelo de calidad de vida de Schalock y Verdugo. Con tal fin se ha llevado a cabo una revisión bibliográfica con un resultado de doce estudios con validez metodológica. Se ha procedido a relacionar los resultados de las intervenciones con los indicadores de cada una de las dimensiones del modelo de calidad de vida propuestos por Schalock y Verdugo. Los resultados informan que la mayor parte de las intervenciones persiguen objetivos relacionados con las dimensiones: bienestar emocional, relaciones interpersonales e inclusión social.
Musicoterapia en Polimicrogiria. Una propuesta de intervención
Authors: Ortega Raquel
Published: July 2020

Este trabajo propone un protocolo de intervención musicoterapéutica para pacientes con polimicrogiria, una enfermedad rara que cursa con un incorrecto patrón de pliegues en la corteza cerebral. Tras realizar una revisión sobre esta patología, se han analizado las necesidades del colectivo abordables desde la musicoterapia estableciéndose unos objetivos terapéuticos. Según estos, se han diseñado las actividades. El protocolo diseñado, se ha testado en una paciente con polimicrogiria (13 meses de edad). Los resultados han sido favorables, ya que las sesiones han potenciado su atención mantenida, disminuido su frecuencia cardiaca, y estimulado su motricidad. También se valoraron los conocimientos previos sobre musicoterapia de los padres a través de un cuestionario, concluyéndose que esta terapia no está considerada oficialmente dentro de las terapias complementarias en polimicrogiria, pero ante los esperanzadores resultados obtenidos, se hace necesario realizar estudios con muestras mayores para poder obtener resultados representativos y establecer un protocolo sólido  y validado.
The possibilities of music therapy in the context of integrated psychotherapy / Knobloch
Authors: Kusý Peter
Published: July 2020

The purpose of this paper is to describe the possibilities of music therapy in the context of IntegratedPsychotherapy / Knobloch. The main pillar of music therapy in the psychotherapeutical process is created byInterpersonal Hypothesis of Music, which is based on an idea that the music reflects interpersonal tendencieswhich independent observer can determine with the certainty beyond a mere chance. Music is able to inducea state that similarly like dreams activates interpersonal processes in person’s Group Scheme, and in fantasyeven satisfies some interpersonal needs and activates interpersonal tendencies. This relates to all people alike.One of the most important tools of music therapy is Circumplex that represents eight categories of interpersonaltendencies (dominance and submission, affiliation and autonomy, exhibition of high and poor quality, fight andescape). There are also used various techniques of passive (receptive) and active components of music therapy –always in accordance with the principle of Interpersonal Hypothesis of Music which together withthe Circumplex and Group Scheme can function as effective secondary tool in therapeutic practice.
Los trabajos de fin de grado en español y en inglés. Retos, y un intento de mejora, de la alfabetización académica en formación inicial de profesorado
Authors: Ahern Aoife Kathleen , Hernando Alicia
Published: July 2020

El presente artículo indaga en el proceso de elaboración de los Trabajos de Fin de Grado, en español y en inglés como segunda lengua, por parte de alumnos de los grados de magisterio, y en el desarrollo de la alfabetización académica que ello supone. Se analizan para estos propósitos textos elaborados por seis estudiantes de los Grados de Educación Infantil y Educación Primaria (bilingüe/mención en inglés), tanto los borradores iniciales sujetos a revisiones con ayuda de las profesoras como sus versiones finales. Las dificultades identificadas no se corresponden con la expectativa de que el proceso tenga una mayor complejidad si se elabora el trabajo en una lengua extranjera en lugar de en la lengua materna, sino que parecen surgir debido a carencias en el conocimiento explícito de las convenciones de los géneros discursivos pertinentes. Como medida para facilitar los procesos de composición de los diferentes apartados de los trabajos, se proponen sendos talleres, en inglés y español, cuya metodología se basa en el modelo «Reading to Learn»/«Leer para aprender», de Rose y Martin (2012-2018), de eficacia demostrada para la mejora de la alfabetización académica a través de la pedagogía de los géneros discursivos. Concluimos ofreciendo una visión de conjunto, en relación con estos talleres, sobre las valoraciones de los estudiantes en cuanto a 1) su utilidad; 2) la efectividad de la metodología empleada durante las sesiones; y 3) el nivel de preparación y confianza para llevar a cabo su TFG alcanzado, una vez finalizadas las sesiones formativas.
El lenguaje de las tecnologías en la formación de maestros
Authors: Andreu Ato Nuria , López-García-Torres Rocío , Saneleuterio Elia
Published: July 2020

Este artículo pretende reflexionar sobre las implicaciones educativas que hoy día tiene la competencia mediática en los procesos de enseñanza-aprendizaje. La evolución de las TIC y, sobre todo, de la tecnología móvil, ha provocado una revolución comunicativa educativa y social que afecta al mundo educativo; los contextos educativos son cambiantes y evolucionan rápido, teniendo que adaptarse a los cambios socioculturales, tecnológicos, etc. Se contemplan tres resortes, a modo de estudio de revisión: los estudios sobre la competencia mediática desde el ámbito neurológico, desde la antropología conectivista y desde la perspectiva del proceso de enseñanza-aprendizaje. Se aportan tres conclusiones principales: los cambios en los modos de comunicación humana han fomentado el uso cotidiano de un lenguaje digital que no puede ser obviado en las aulas y que se concreta en la necesidad de desarrollar la competencia mediática; siendo imprescindible para lograrlo la incorporación de las TIC en las aulas, que repercute asimismo en la mejora de funciones ejecutivas básicas que potencian los aprendizajes; finalmente, la formación docente presenta una tendencia creciente hacia el compromiso para responder adecuadamente a las exigencias de la educación de un mundo tecnologizado, también contemplado en las leyes educativas actuales y cuya complementariedad puede interpretarse como garantía hacia un desarrollo adecuado de la competencia mediática en las generaciones del futuro que se formen en un uso fluido y responsable de las TIC y las TAC.

Colour Preference for Two-Colour Combinations
Authors: Stanikūnas Rytis , Puišys Laimonas , Radzevičienė Aldona , Vaitkevičius Henrikas
Published: July 2020

What determines which colour combinations will be attractive to a person and which will not? Is colour attractiveness only a subjective human experience, or can we predict it based on physical colour parameters? One of the pioneers of the attraction of colour theories was Michel Eugène Chevreul (1786–1889). He distinguished two types of colour harmony – analog colour and contrast – and tried to describe what harmonics are based on physical colour parameters. This was later done by other scientists. Later, semantic evaluation of colours was introduced and factor analysis attempted to identify emotions caused by colours or combinations of colours. The aim of this research is to test whether there is a consistent pattern of judgments of colour combinations under controlled conditions and, if so, to what extent they are influenced by the objective physical characteristics of those combinations. Subjects. The study involved 40 students (20 men, 20 women). All subjects had normal colour vision and were not related to fine art. Research tools. The study used 8 colours: 4 opponent (green, red, yellow and blue) and 4 additional (orange, lettuce, blue and purple). The 28 colour combinations (made up of two different colours) were composed of those 8 colours and printed onto cardboard card where each colour had area of 80 mm x 80 mm. Questionnaire of 40 adjectives consisting of 20 pairs of antonyms were used for semantic colour assessment. Procedure. The investigation was conducted in a dark room. Initially, all 28 cards with colour combinations were placed randomly on a desk lit by a 40 cm high fluorescent lamp (4000K correlated colour temperature). The subject was asked to select one of the cards with the most preferable colour combination, to write its code on the questionnaire and to mark all the epithets in the questionnaire which suits this colour combination. The same procedure was applied to the all other cards. One experiment lasted 35–50 minutes. Results and conclusions. Independent component analysis distinguished 4 dimensions describing colours: pleasure, energy, purple color and strength. Logistic regression analysis was run on colour factor loadings to discriminate colour combinations into two groups: liked and disliked colour combinations. It shows that that colour combination could be predicted as being liked or disliked with 85% probability. Adding physical colour parameters to the regression increases prognostic probability to 92 %. Also a relationship between subjective factors and physical characteristics of colour combinations was found. Pleasure correlates with hue contrast and strength with saturation contrast. It can be argued that the reliability of colour combinations is determined by both subjective and physical factors.
Increasing Vaginal Chlamydia Trachomatis Testing in Adolescent and Young Adults
Authors: Brigham Kathryn S. , Peer Michael J. , Ghoshhajra Brian B. , Co John Patrick T.
Published: July 2020

OBJECTIVE:

The Centers for Disease Control and Prevention recommend testing for Chlamydia trachomatis in sexually active female patients <25 years old using nucleic-acid amplification tests (NAAT) from a vaginal swab. Our providers were typically testing using the less sensitive urine NAATs. We aimed to increase the percentage of urogenital C trachomatis NAATs performed by using vaginal swabs in adolescent female patients ages 10 through 20 years from 1.4% to 25%.

METHODS:

We implemented 3 interventions at 3 pediatric practices over 12 months including education, process standardization, and cross-training. We used statistical process control to analyze the effect of interventions on our primary outcome: the percentage of urogenital C trachomatis tests performed with a vaginal swab. Our balance measure was the total number of urogenital C trachomatis tests.

RESULTS:

There were 818 urogenital C trachomatis tests performed: 289 before and 529 after the first intervention. Of urogenital C trachomatis tests in the preintervention time period, 1.4% were performed by using vaginal swabs. We surpassed our aim of 25% 6 weeks after the first intervention. We noted sustained improvement after the second intervention, with an average of 68.3% of tests performed by using vaginal swabs for the remaining postintervention period. There was no difference in the overall number of urogenital C trachomatis tests pre- and postintervention.

CONCLUSIONS:

Using quality improvement methodology and implementing easily replicable interventions, we significantly and sustainably increased use of vaginal swabs. The interventions standardizing processes were associated with a higher impact than the educational intervention.
A Community Development Program and Reduction in High-Cost Health Care Use
Authors: Chisolm Deena J. , Jones Claire , Root Elisabeth D. , Dolce Millie , Kelleher Kelly J.
Published: July 2020

Adverse housing and neighborhood conditions influence child health. The Healthy Neighborhoods Healthy Families community development initiative was established in 2008 to address housing, education, employment, and other neighborhood-level, child health–influencing factors on the south side of Columbus, Ohio, with the goal of improving child health and well-being. In this article, we discuss the path from advocacy to outcomes analysis in this initiative and assess changes in high-cost health care use by children in the target area over the first decade of implementation. Change in health care use was measured by using a difference-in-differences approach comparing emergency department visits, inpatient stays, and inpatient length of stay in the intervention neighborhood and a propensity score–matched, pooled comparator neighborhood in the same city. The baseline and follow-up periods were August 2008 to July 2010 and August 2015 to July 2017, respectively. Findings from this analysis reveal that compared to 2 pooled comparison neighborhoods, the intervention neighborhood trended, nonsignificantly, toward greater decreases in inpatient stays and emergency department visits and smaller increases in length of stays. These results suggest that our community development activities may be influencing health care use outcomes, but in the early years of the intervention relative changes are modest and are variable based on the definition of the intervention and comparator neighborhoods. Lessons learned in expanding from advocacy to analysis include the importance of building multidisciplinary teams that can apply novel approaches to analysis, moderating expectations, and retaining focus on the broader social context.
Pluralidad del evento en el castellano peruano: construcciones frecuentativas «pasarse» + gerundio y «parar» + gerundio
Authors: Martel Paredes Víctor Arturo
Published: July 2020

En este trabajo, describiremos el comportamiento sintáctico y semántico de dos formas verbales comunes en el castellano peruano: parar+gerundio y pasarse+gerundio. Lo interesante de estas formas, al ser casi homófonas, es su distinta estructura sintáctica: mientras una es un verbo de ascenso, otra es del tipo llamado de control. No obstante, aduciremos que el valor frecuentativo de ambas formas genera una lectura de pluralidad del complemento verbal que las acompaña: mientras parar funciona como un operador auxiliar del verbo, pasar coerciona o fuerza una lectura plural debido a su contenido léxico. Por otro lado, mostraremos que ambas formas verbales se encuentran en un proceso de gramaticalización, es decir, en una pérdida de contenido léxico y ganancia de rasgos funcionales, aunque, en mayor medida, parar, en su función auxiliar, tiene un mayor avance en dicho proceso.
Retóricas revolucionárias na linguística: recepção de teorias e novidade científica
Authors: De Oliveira Batista Ronaldo
Published: July 2020

O objetivo deste artigo é discutir a noção de revolução na história da linguística a partir da observação da retórica de linguistas circunscritos a determinadas comunidades de pesquisadores. Propõe-se uma interpretação (a partir de um quadro sociorretórico de análise em Historiografia Linguística) de dois momentos da história da linguística brasileira (considerada exemplo analítico a sustentar uma reflexão meta-historiográfica) em que linguistas advogaram por rupturas revolucionárias na ciência da linguagem. Constituem-se como material de análise: (1) a resenha de Miriam Lemle de 1967, marco da recepção brasileira à Gramática Generativa; (2) o manifesto que elaborou o programa da Gramática Construtural em 1973. Entende-se que uma análise dos posicionamentos discursivos dos cientistas permite evidenciar o humano na prática científica, muitas vezes negado, ainda que presente nas disputas intelectuais e institucionais que caracterizam o pensamento científico.
Entre la morfología y la sintaxis: una aproximación a la creación de verbos con pronombre acusativo «la»
Authors: Arellano Nicolás
Published: July 2020

Este artículo busca describir un proceso novedoso de formación de palabras del español rioplatense en que el pronombre acusativo femenino la puede unirse a bases patrimoniales y neológicas y, en particular, a cuatro tipos de bases verbales: no derivadas (colgarla), derivadas de sustantivos y adjetivos (gordearla), préstamos léxicos (flopearla) y nombres propios (berlinearla). A través de una base de datos propia constituida por ejemplos encontrados en redes sociales, nuestro objetivo es identificar si este proceso se encuentra a medio camino entre la morfología y la sintaxis, porque comparte características de ambos niveles, o bien puede delimitarse dentro de alguno de ellos. El análisis de la referencia, idiomaticidad, regularidad y productividad del pronombre la y las nuevas unidades verbales indica que, en efecto, este se encuentra en un estado intermedio, ya que pueden postularse dos tipos de creación distintos, que se corresponden con dos instancias de formación: una primera más sintáctica y una posterior con características de evolución morfológica.
¿Entrenamiento perceptivo o instrucción explícita? Percepción y producción de los patrones de voice onset time iniciales del inglés (le) por estudiantes brasileños
Authors: Alves Ubiratã Kickhofel , Luchini Pedro Luis
Published: July 2020

En inglés, el voice onset time (vot) desempeña un rol crucial en las distinciones entre oclusivas sordas y sonoras en posición inicial de palabra. La combinación de las prácticas de entrenamiento perceptivo e instrucción explícita ofrece beneficios para la percepción y producción de esos segmentos por estudiantes de inglés. En este trabajo investigamos si la aplicación de cada una de esas técnicas brinda resultados positivos en términos de percepción y de producción de las oclusivas sordas aspiradas /p/, /t/ y /k/. Para ello, participaron 30 estudiantes brasileños de inglés, divididos en tres grupos, cada uno expuesto a diferentes tratamientos. Los participantes realizaron tareas de identificación y producción oral en tres momentos distintos (pretest, postest y postest tardío). Los resultados muestran que el entrenamiento perceptivo promueve mejoras en la percepción, pero no así en la producción. Por su parte, la instrucción explícita con prácticas de producción genera avances en la producción únicamente.
CLIL and Comprehensive Sexual Education: A Case of Innovation From Argentina
Authors: Banegas Darío Luis , Lauze Cristina
Published: July 2020

Social issues are believed to enrich English language teaching with meaningful topics. In this article we describe and reflect on an innovative practice which combined content and language integrated learning with comprehensive sexual education at a state secondary school in Argentina. By law, comprehensive sexual education must be included across the Argentinian curriculum and English language learning cannot be the exception. Therefore, we designed and implemented a collaborative-driven innovation that allowed learners to learn English and comprehensive sexual education with a focus on authentic materials, purposes, and tasks. The innovation was developed over a month and it involved learners delivering presentations on comprehensive sexual education topics. Reflections on the effect of the innovation and possible future directions are included.
Ensuring Quality in a Foreign Language Tutoring Program for Future Teachers

Published: July 2020

This article reports on an exploratory, mixed methods study aimed at identifying the methodological and epistemological criteria necessary to ensure the quality and a self-revision process of a pilot tutoring program offered to students enrolled in the BEd in philology and languages (English and French programs) at Universidad Nacional de Colombia, Bogota. Ten students of the French and English Philology programs and six tutors voluntarily participated in the research. The data were collected through document reviews, focus group discussions, and questionnaires completed by the tutors and tutees. The study revealed that a comprehensive, personalized tutoring plan was needed. Likewise, self-efficacy development, human capital, as well as technological and physical resources must be considered in order to determine the weaknesses, strengths, opportunities, and overall impact of the program.
A new set of tools for Ethnobiologist in the COVID-19 Pandemic
Authors: Ladio Ana H.
Published: July 2020

This article will develop a series of ideas for ethnobiologists to consider in their professional field from now on. One of the things we have most learned about indigenous communities is the importance of being committed to maintaining the networks of life and the protection of diversity. Considering the warnings given by indigenous groups regarding past and future imbalances of Nature, what will happen to ethnobiological work in the future, and is what we do really necessary? What lines of action, conflict, alliances and controversies lie ahead of us. The so-called new normality urges us to make changes in our discipline, and therefore we should be able to count on a new box of tools. In a metaphorical sense, I will call these tools a set of premises that should never be lacking in the future; we must be alert to the signs of change, the omens and the previous experiences of local communities.  These pandemic times have prioritized the voices of “experts”, who impose hegemonic scientific systems as if they were the only option. Indigenous peoples are neither heard nor valued, even though they are some of the worst affected by this pandemic, being subject to large-scale ethnocide at this moment. Our challenge as ethnobiologists should be to build bridges and be agents of change, so that multiculturality and interculturality can be made visible and promoted.
The study of the soil of the base of the Krasnoyarsk territory and the method of strengthening
Authors: Zaitsev Andrey , Artyushenko Igor
Published: July 2020

Railways in Russia rightfully occupy one of the key places in the national economy in connection with the geographical conditions, technological features of the economy and the possibility of maximizing the use of the country's transit potential. The problem of modernizing the transport system of Russia, its adaptation to the requirements of the functioning of the national economy and foreign economic relations is becoming increasingly relevant for the regions of the North. As part of the main stage of the expedition “Transpolar Highway”, conducted by the Russian Geographical Society (RGS) together with the Russian University of Transport (RUT) from September 19 2019 to October 15 2019, specialists from the Russian University of Transport examined the territory of the Krasnoyarsk Territory to assess the possibility of designing and building tracks messages in these regions. The lack of transport infrastructure, the unpredictability of the behavior of frozen soils during freezing-thawing, the presence of weak soils in the foundations of structures, difficult climatic conditions, all these factors determine the complexity of construction in these regions. This article describes the determination of the strength characteristics of soils using a dynamic Panda penetrometer-density meter in the field. Conclusions are made about the appropriateness of using these soils in the foundations of structures. Due to the lack of quarries for the production of crushed granite in the Norilsk region and the difficulty of transporting this material, the use of Norilsk metallurgy waste as a replacement for crushed stone was analyzed. The results presented in the article are part of the dissertation research I. Artyushenko "Reinforcement of the subgrade base with vertical columns of crushed stone in areas with permafrost soils"
Investigation of the frequency of free vibrations for pipelines with different physical and mechanical properties of the material
Authors: Dmitriev Andrey
Published: July 2020

This paper raises the question of a new approach to the dynamic calculation of
thin-walled underground pipelines of large diameter, which is based on the application of the
Vlasov-Novozhilov half-time theory of medium-bend shells, which ignores the M1 moments that bend the cylindrical shell in the longitudinal direction, since they are much smaller than the M2 moments that bend it in the transverse direction. The resolving equation for this approach is a homogeneous
4th-order differential equation that uses two boundary conditions at each end to solve it. The resulting equation takes into account the parameter of the longitudinal force, the value of the internal pressure, the coefficient of elastic resistance of the soil, the parameter of thinness, as well as the attached mass of the soil.
Based on the data obtained from the derived formulas, the frequency characteristics of
thin-walled underground pipelines of large diameter with different physical and mechanical properties are determined depending on the length of the element, as well as ground conditions. It is established that the minimum frequencies for the shell form of vibrations in various ground conditions are realized only for steel pipes, and for polyethylene and fiberglass pipes, depending on the coefficient of elastic resistance of the soil, they can be realized both in the rod and shell form.
At the same time, using a dynamic stability criterion, derived expressions to determine the critical external pressure, taking into account the pipe length and the number of half waves in the cross section in which there is a constructive denial of the pipeline. Based on this expression, a formula for determining the critical depth of laying for thin-walled pipelines is obtained.
Optimization of project management processes in construction
Authors: Agapkina Maria , Ovchinnikov Ilya
Published: July 2020

The article considers the main reasons for the bankruptcy of construction organizations. Some advantages of the forthcoming pricing reform have been identified and pricing abroad has been considered. Attention is paid to the general concepts of project management and the importance of competent project management.
To carry out high-quality control over the implementation of objects, the Spider Project software package is considered, which is ideal for the construction industry. The program is based on a unique methodology for calculating the schedule and its optimization, based on the volume of work and the performance of the assigned resources. Also in the article you can find other advantages or functions of the program. But the main and convenient function is “programming” or importing tables of the “text file” type into the Spider Project. Working with tables will speed up the calculation of the budget of expenses and incomes at the pre-bidding stage and in the future will allow you to quickly create a resource-calendar schedule in the program. The so-called acceleration of the work of engineers can occur due to the preparation of estimates by the resource method, which will reflect the actual costs of the work or materials. By analyzing the estimate in the Grand Estimate program, you can get the necessary data for further work with the work schedule in the Spider Project.

Published: July 2020

ABSTRACT Objectives: to compare the effectiveness of the decentralized automated drug dispensing system with pockets. Methods: an effectiveness study based on a systematic review guided by the question: for patients admitted to hospital units, is the use of automated drug dispensing effective for reducing medication errors when compared to manual unit dose dispensing? The evidence was evaluated by the Grading of Recommendations Assessment, Development and Evaluation and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses instrument, used in the report. Results: the sample was composed of 15 studies and none of them directly compared both technologies; however, the meta-analysis showed that there is no difference in effectiveness between them [OR 1.03 95%CI (0,12 - 8,99)]. Conclusions: the conclusion is that the recommendation in favor of the automated dispensing system is weak.

ABSTRACT Objective: to understand the vulnerabilities of older adults with physical disabilities regarding their body, physical and social environments. Method: this was a qualitative study based on Alfred Schütz’ social phenomenology, with 15 older adults with physical disability from Cuiabá, state of Mato Grosso, Brazil. Open-ended questionnaires were administered to the participants in 2017. The units of meaning that emerged were organized into thematic categories. Results: physical decline, associated with the permanence of environmental and social barriers intensified the vulnerabilities of older adults. Gaps in health services are mitigated by informal social support networks and access to work was a form of social inclusion. Final considerations: vulnerabilities in the old age of persons with physical disabilities did not reside only in the body dimension, but also the physical and social environment, countering healthcare models based on the logic of reverting their dysfunctional body.

ABSTRACT Objectives: analyze the association between the level of HIV knowledge among young people from Amazonas region, their sociodemographic profile and infection risk factors. Methods: cross-sectional analytical study, which used a structured questionnaire containing questions about sociodemographic, behavioral aspects and HIV knowledge. Data were grouped by sex and underwent ordinal and binary logistic regression analysis. Results: the students had an HIV knowledge deficit, associated with a low educational level of their parents and low family income. The most frequent risk factors were lack of knowledge on the part of female students regarding proper male condom use, their infrequent use in sexual relations and failure to do HIV testing. There was an association between level of knowledge and use of dating apps by female students. Conclusions: there was no association between level of knowledge and the preponderant risk factors, but the students’ knowledge deficit rendered them more vulnerable to infection.

ABSTRACT Objectives: to identify the aspects related to professional training and autonomy of undergraduate nursing teachers of a public institution in Brasília, Federal District, in order to contribute to the course management and qualification. Methods: mixed method study conducted with 77 teachers. A semi-structured questionnaire was applied, where quantitative items were evaluated through the Student’s T and ANOVA (p<0.05%) parametric tests. The qualitative part underwent content analysis with use of the IRAMUTEQ software and descending hierarchical classification. Results: the training of professionals was focused mostly (67.5%) on their initial area of expertise, and their mean values in autonomy-related factors were low and moderate. Two categories emerged in the qualitative analysis: “Identifying teacher autonomy” and “Applying teacher autonomy”. Conclusions: understanding the meaning and degree of autonomy perceived by teachers can foster the reflection on the praxis and enhance their performance.
EDUCAÇÃO E AGENCIAMENTOS EM PERIFERIAS URBANAS: A PRODUÇÃO DE ALTERNATIVAS LABORAIS ENTRE JOVENS
Authors: PINHEIRO LEANDRO R
Published: July 2020

RESUMO: O artigo parte das condições de trabalho de jovens na atualidade para discutir tomadas de posição na produção de alternativas laborais associadas à condição juvenil contemporânea, destacadamente à fruição de práticas culturais em contextos de periferia urbana. As informações consideradas resultaram da incursão a diferentes localidades socialmente vulnerabilizadas da cidade de Porto Alegre, entre 2013 e 2016, quando realizamos entrevistas narrativas e nos detivemos à observação de práticas produzidas por moradores dos bairros visitados. As contribuições de Danilo Martuccelli são os principais referentes para as análises empreendidas sobre a ‘prova social’ do trabalho e suportes relacionados. Observamos a produção de capital cultural entre pares, o que tem suportado a conquista de ocupações em espaços sociais articulados à “forma escolar”. Assim, programas de integralização da educação, inicialmente experienciados como suportes, são convertidos em campo de ação mediante agenciamentos operados pelos jovens.

RESUMO: Este artigo estuda as competências e funções dos tutores online em educação a distância (EaD). Envolve uma revisão sistemática de literatura em língua portuguesa e a elaboração de um modelo teórico para orientar a formação de tutores. Os textos selecionados na revisão são analisados qualitativamente por um processo de codificação e categorização com o suporte do software MAXQDA. Códigos baseados na literatura são inicialmente propostos, mas outros são incluídos durante a análise. O modelo apresentado como resultado da pesquisa levou em consideração a frequência da ocorrência das categorias nos textos. Dentre as competências dos tutores online, destacam-se: gerenciais, saberes disciplinares, saberes pedagógicos, habilidade de comunicação, competências socioafetivas e habilidades tecnológicas. As funções básicas do tutor online em EaD, identificadas na pesquisa, são: gerenciais, pedagógicas e sociais. O modelo proposto procura relacionar as competências com essas funções. Deve servir, nesse sentido, para orientar a formação de tutores, contrapondo-se à tendência de precarização do trabalho docente online.
