Authors:   Lecturer, Government Girls Polytechnic Moradabad, Lucknow, India., Singh* Kamal , Sahay Kuldeep ,   Professor, IET, Lucknow, India.
Published: April 2020

In this paper different non-dissipative snubber circuits in which RCD snubber circuit, CD snubber circuit, LCD snubber circuit and proposed LCD snubber circuit are implemented in SEPIC converter to obtain high static gain. The snubber circuit is used for the protection of the power semiconductor devices. The requirement of high static gain is necessary in different applications of dc-dc converters, so that efficient operation of the system can be obtained. The basic idea of the snubber circuit used in this paper is to reduce the turn-on and turn-off losses at the time of switching processes. For this purpose, inductor and capacitor combination is required so that during turn-on process, sudden change in current through semiconductor device which is used as a switch, can be reduced. Similarly, during turn-off process, sudden change in voltage across switch can be minimized. Here, different snubber circuit based SEPIC converters are analyzed with the help of MATLAB simulink and results of output voltages and currents are obtained. The results are summarized which clearly shows that the proposed SEPIC converter has high static gain in comparison of the others topologies. Hence non-dissipative snubber circuit based SEPIC converter provides high efficiency than the other modifications in SEPIC converter.

Cloud is the normally utilized file to store, transmit, get and share mixed media substance. Cloud utilizes web to play out these undertakings because of which information turns out to be increasingly inclined to assaults. Information security and protection are compromised. This can be kept away from by constraining information access to confirmed clients and by concealing the information from cloud benefits that can't be trusted. Concealing information from the cloud administrations includes scrambling the information before putting away it into the cloud. Information to be imparted to different clients can be encoded by using Cipher Text-Policy Attribute Based Encryption (CP-ABE). CP-ABE is utilized which is a cryptographic method that controls access to the scrambled information. The matching put together calculation based with respect to bi-linearity is utilized in ABE because of which the prerequisites for assets like memory and force supply builds rapidly. Most of the gadgets that we use today have restricted memory. Therefore, a productive blending free CP–ABE get to control plot utilizing elliptic bend cryptography has been utilized. Blending based calculation is supplanted with scalar item on elliptic bends that lessens the important memory and asset prerequisites for the clients. Despite the fact that matching free CP-ABE is utilized, it is simpler to recover the plaintext of a mystery message if cryptanalysis is utilized. Along these lines, this work proposes to consolidate cryptography with steganography in such a manner by installing crypto content into a picture to give expanded degree of information security and information proprietorship for problematic sight and sound applications. It makes it harder for a cryptanalyst to recover the plaintext of a mystery message from a stego-object if steganalysis were not utilized. This plan fundamentally improved the information security just as information protection.

Hybrid Precoding for Millimeter Wave RoF Systems
Authors: Alghorani Yahia , Ikki salama
Published: April 2020

Large propagation path loss and limited scattering

of millimeter wave (mm-wave) channels create new challenges for physical layer signal processing. Hence, in this paper, we propose a photonic hybrid precoding model for mm-wave radio-over-fiber systems that overcomes hardware constraints on radio frequency precoding. With the help of analog photonic beamformers, the hybrid precoding strategy combats the large losses of mm-wave and mitigates inter-user interference, which in turn reduces the number of RF chains required to perform digital beamforming. The simulation results show that the proposed model can offer significant coding gains over conventional RF hybrid precoding systems. Unlike RF hybrid precoding systems, the photonic hybrid precoding systems can provide higher data rates and lower error rates in multi-user transmission scenarios.

Authors: Babintseva N. A.
Published: April 2020

The long-term results of studies on the formation of productivity in apple trees on the medium-sized rootstock MM-106 with an intermediate insert of a low-growth rootstock EM - IX are given. The objects of research are cultivars: Golden Delicious, Jonagold, Kimmeriya, Krymskoe with a planting pattern of 3.5 x 1.25 m and 3.5 x 1.75 m. Trees are formed according to the type of free spindle. As a result of the research, a high potential application of the combined stock (with intercalary insert) in the garden, which provides early fruiting, a rapid increase in yield, high marketability and keeping quality of fruits, is revealed. Domestic intensive gardens on a combined stock can be created in the conditions of the Crimea without any support, which saves material resources for their laying. The formation of trees according to the type of free spindle in the gardens makes it possible to compact the planting of trees in a row by 20-25% and reduce the amount of labor expended on pruning trees and harvesting 1.6 times, depending on the cultivar. Realization of the productivity potential in such gardens is determined by the high level of agricultural technology with the obligatory implementation of technological methods.

Published: April 2020

Objectives: To determine if patients allow medical students to perform less invasive procedures compared to more invasive procedures, and how this is related to patient demographics and previous experience with medical students. Methods: A cross-sectional survey was conducted in six areas of Birmingham, UK. All members of the general public over the age of 18 were eligible, excluding non-English speaking people and those with cognitive impairments. Respondents were asked to rank their willingness for medical students to perform history taking/examinations and clinical procedures of varying degrees of invasiveness. Results: We received a total of 293 responses. For both history taking/examinations and clinical procedures, people were more willing to allow medical students to perform less invasive procedures rather than more invasive procedures. White and older people were more willing to allow all history taking/examinations procedures; additionally, women were more willing to allow history taking. White, female, and older participants were more willing to allow blood pressure measurement; whilst older people and those with previous experience were more willing to allow venepuncture. No significant associations were found for intubation. Conclusions: The public is less willing for medical students to perform more invasive procedures. This may severely limit opportunities to attain clinical competencies.
“I really wanted to be able to contribute something”: understanding student motivations to create meaningful global health experiences
Authors: Hetherington Erin , Hatfield Jennifer
Published: April 2020

Background: Global health is an area of increasing interest among health professionals, students and educators. This study aims to explore students’ motivations and experiences with an undergraduate global health research program in low and middle-income countries and to assess student learning and areas for program improvement. Methods: All students participating in the Global Health Research Program at the University of Calgary in the summer of 2009 were asked to participate in the study (n=11). In-depth interviews were conducted with students prior to departure and upon their return. Discourse analysis was used to identify interpretive repertoires and to determine how the use of repertoires improves our understanding of students’ experiences. Results: Prior to departure, students were highly motivated to "give back" to host communities.  Upon return, students felt that their experience had been more about "building relationships" with others than individual contributions to hosts. Discussion: Students' altruistic motivations dominated the discourse, and most students incorporated core concepts from a preparation course only after their international experience.  Extensive preparation, supervision and follow-up support can mitigate many of the risks of short-term global health experiences while providing a safe opportunity for significant learning.
Surgeon Involvement in Pre-Clinical Medical Education: Attitudes of Directors of Education
Authors: Turner Simon , Diederichs Brendan , De Gara Christopher
Published: April 2020

Background: Application rates to surgical residencies have shown a downward trend recently. Introducing students to surgeons early in medical school can increase interest in surgery as a career and enhance the instruction of important surgical topics. Directors of undergraduate medical education have unique insight and influence regarding the participation of surgeons in pre-clinical education. Methods: To understand the attitudes of these educators towards surgeons as teachers in pre-clinical programs, a survey was administered to the directors of undergraduate medical education at each of the English-language medical schools in Canada. Results: Educators estimate the participation of surgeons in all categories of pre-clinical education to be low, despite being valuable, and think that it should be increased. The most significant barrier to participation identified was a lack of surgeons’ time. Conclusions: Despite the value of surgeons participating in pre-clinical education, their rate of participation is low. Steps should be taken to facilitate the involvement of surgeons in this phase of education, which may lead to improved education for students and increased student interest in surgery residencies.
Teaching evolution to psychiatrists in Venezuela: comparison with medical students and other medical specialists: a pilot study
Authors: Baptista Trino , Aldana Elis , Angeles Felix , Delgado Heidy
Published: April 2020

Introduction: The teaching of evolution theory (ET) in medical programs has received scant attention in the literature. In this report, we first describe the main applications of ET in medicine. Second, we present the evaluation of an interactive seminar on ET given to groups of medical students, psychiatrists, and other medical specialists. Methods: A two-hour, four-module, interactive seminar was conducted with separate groups of 27 psychiatrists, 15 family doctors, 18 neurologists, 13 physiatrists, 12 internists, and 24 sixth-year medical students without formal training in ET. Their knowledge of ET before and after the seminar was rated on a validated analogical scale (0-12). In addition, the perceived relevance of the information for the participants’ professional activity was assessed. Results: Score averages and medians before the seminar were below 6, suggesting low to moderate knowledge. The students' scores did not differ significantly from those of the physicians except on the Hominization item, where they scored lower than the physicians (p = 0.02). The psychiatrists’ scores did not differ from those of the other groups before the seminar, but after the seminar the increase in their scores on a number of items was significantly smaller than that of the other groups. While all groups scored 10 or more when assessing the relevance of the information, the psychiatrists had the lowest score (p = 0.024). Discussion: The results show the adequacy of short programs to enhance knowledge on ET. This may assist medical educators to develop comprehensive and compulsory courses. Future studies must explore whether psychiatrists are relatively reluctant or ambivalent to accept evolution concepts and proposals.

Authors: Bishop Lisa , Duggan Norah , Flynn Heather
Published: April 2020

Background: “Questions in Practice” (QUIP) rounds are used to encourage residents to quickly find, evaluate, and incorporate information into clinical practice. It is an opportunity for residents to identify a clinical question, research the answer, present the evidence, and discuss how to apply it to practice. The value of using this method to teach residents has not been evaluated. Methods: A sampling of all first and second-year family medicine residents enrolled in the Memorial University Family Medicine program were invited to participate in the survey. The survey gathered information about the residents’ current experiences with answering clinical questions, their experience during QUIP rounds, and the value of an interdisciplinary approach. Results: The response rate was 91% (42/46). Medical websites (45%) and journal article indexes (34%) were most often used. Through QUIPs, 50% of the students identified new methods to retrieve answers, 80% considered it a useful learning experience, 75% had improved confidence, and clinical knowledge improved in 97%. Conclusions: Residents are familiar with many general sources of medical information, and QUIPs helped improve confidence in their knowledge and ability to answer questions. QUIPs appear to be a useful tool for teaching information resources and how to interpret and apply evidence to clinical situations.

Published: April 2020

La utilización de papel y cartón de recuperación como materia prima para la fabricación de papel y cartón reciclado, presenta numerosas ventajas al medio ambiental y económico. Sin embargo, también tiene graves inconvenientes debido a la cantidad de contaminantes que se introducen en el sistema. Los contaminantes que se encuentran en forma de materia disuelta y coloidal no pueden ser eliminados por los procesos mecánicos convencionales y cuando se desestabilizan, por un cambio brusco de las condiciones del sistema, son responsables directos de la formación de manchas y agujeros en el producto final. El objetivo del presente trabajo es desarrollar un procedimiento para determinar la presencia de materia disuelta y coloidal en el agua del proceso papelero, de manera práctica y precisa. Las aguas caracterizadas, se desestabilizan con un polímero catiónico, favoreciendo la formación de depósito diseñado para tal fin, que permite llevar a cabo la determinación cuantitativa mediante un sistema de análisis Físico Quimico. Con el método desarrollado, una vez validado y determinada su reproductividad, se lleva a cabo un estudio con aguas reciclada obtenida a partir de las suspensiones de pasta que contienen los contaminantes propios del proceso del reciclado de papel, tales como: adhesivos, ceras, jabones de destintado, etc. Se estudia el efecto que ejercen distintas variables, como la naturaleza del contaminante, la presencia de aditivos de destintado, la naturaleza de los agente de desestabilización y las características del medio (Ph, Temperatura, Solidos Totales, DQO, DBO5, Aceites y Grasas   etc.); así mismo, se lleva a cabo un estudio de las aguas del proceso, con  materia disuelta y coloidal contenida en muestras de diferentes tipos de materia primas: papel mixto, periódico y cartón reciclado, obteniendo los resultados después del tratamiento Físico Quimico en promedio. (Ph = 8.4; Temperatura = 26.5°C; Solidos Totales = 150.26 mg/L; DQO = 750.82 mg/L; DBO5 = 300.24 mg/L; Aceites y Grasas = 48.56 mg/L etc.); en la fabricación de planchas de Fibras aglomeradas en la empresa Inpetfa sac.

Published: April 2020

Si alguna vez cuando se ha sido un niño, se subió a una escalera y se cayó, probablemente este episodio desanimó en su vida de infante cualquier interés por volverlo a intentar. Es posible que en su mente haya considerado que las escaleras eran muy altas o cortas, grandes o feas, e incluso, malas. En términos materialistas se puede plantear que, toda esta serie de características asociadas con la escalera están pensadas desde un plano subjetivo, una noción idealista y emocional que se enfrasca en lo que se siente como el miedo debido al trauma. A diferencia de ello, una visión más objetivista tendría que aceptar que las escaleras son seres inanimados, objetos útiles al conocimiento, pero que no participan intencionalmente de la experiencia sensible del sujeto. Este último análisis está fundamentado en una corriente filosófica denominada realismo.
Organização doméstica, tradição de conhecimento e jogos identitários:
Authors: Mura Fabio , Silva Alexandra Barbosa da
Published: April 2020

Partindo de uma reflexão sobre a noção de “povos tradicionais”, o presente trabalho intenta discutir como, a partir de contextos históricos e sociais específicos, organização doméstica e tradição de conhecimento se entrecruzam, em jogos identitários multiescalares. para tal intento, procede-se a um cotejamento entre dois exemplos etnográficos – os kaiowa de mato grosso do sul e os tabajara do litoral sul da paraíba –, ressaltando-se o fato de que o grupo doméstico se revela uma unidade fundamental, ao se constituir como base para, por um lado, a construção de comunidades étnicas e comunidades políticas locais, enquanto que, por outro, para a produção e reprodução de quadros morais e cosmológicos, contribuindo em dar sentido às experiências diversificadas de seus integrantes.
Redefinições nos processos de socialização das crianças rurais
Authors: Stropasolas Valmir Luiz
Published: April 2020

Constatamos que em estudos e projetos institucionais relativos à família brasileira, a atenção tem se voltado sobretudo às questões e problemáticas que afetam as mulheres e os jovens, verificando-se, ainda, a invisibilidade das crianças rurais. Isso configura uma lacuna no campo das ciências sociais dedicadas aos estudos rurais na abordagem da condição social da infância e das mudanças nos processos de socialização desse segmento no cenário da agricultura familiar. Este artigo tem como objetivo analisar as redefinições emergentes nos processos de socialização das crianças rurais, a partir de uma pesquisa qualitativa realizada recentemente pelo autor em comunidades rurais de Santa Catarina, no Sul do Brasil.
A trajetória da algaroba no semiárido nordestino: dilemas políticos e científicos
Authors: Cunha Luis Henrique , Gomes Ramonildes Alves
Published: April 2020

A introdução da algaroba (Prosopis juliflora (sw) D.C.) no semiárido nordestino, iniciada na década de 1940, é um exemplo paradigmático do que chamaremos aqui de estratégias de eco-agro-inovação para o desenvolvimento, em que diferentes poderes/saberes são mobilizados e se confrontam, alterando a percepção sobre constrangimentos e vulnerabilidades do ambiente natural. Inspirados na ecologia política e adotando abordagem processual, analisamos a trajetória da algaroba no semiárido ao longo dos últimos 60 anos em termos das lógicas/racionalidades e interesses que moldaram políticas de incentivo ao plantio da espécie na região e que informam as denúncias mais recentes da planta como invasora e ameaça à vegetação nativa. O debate sobre a algaroba expressa dilemas políticos e científicos, que vão além do enquadramento como problema ambiental. A espécie é um elemento importante de redes sociais e econômicas e a compreensão sobre essas redes deve informar pesquisas agronômicas e ecológicas sobre os impactos da algaroba na região.
Computer Time Minimizing for the Circuit Optimization
Authors: Zemliak Alexander
Published: April 2020

The solution of a problem of analogue circuit optimization is mathematically defined as a controllable dynamic system. In this context the minimization of the processor time of designing can be formulated as a problem of time minimization for transitional process of dynamic system. A special control vector that changes the internal structure of the equations of optimization procedure serves as a principal tool for searching the best strategies with the minimal CPU time. In this case a well-known maximum principle of Pontryagin is the best theoretical approach for finding of the optimum structure of control vector. Practical approach for realization of the maximum principle is based on the analysis of behaviour of a Hamiltonian for various strategies of optimization. It is shown that in spite of the fact that the problem of optimization is formulated as a nonlinear task, and the maximum principle in this case isn't a sufficient condition for obtaining a minimum of the functional, it is possible to obtain the decision in the form of local minima. The relative acceleration of the CPU time for the best strategy found by means of maximum principle compared with the traditional approach is equal two to three orders of magnitude.

The aim of this study is to investigate the influence of organizational culture on organizational commitment in the context of the Vietnam telecom industry. The model was tested with a sample of 324 employees working for telecom companies. The result from the partial least squares method (PLS) using SmartPLS 3.0 program revealed a good fit between collected data and measurement scales which were introduced and developed in the Western contexts. Besides, the findings showed that the six dimensions of organizational culture had positive impacts on organizational commitment decreasingly: innovativeness, teamwork, training and development, reward and recognition, organizational communication, empowerment. This discovery highlighted the importance of organizational culture in enhancing employee commitment towards the organization as well as calls the management attention to these dimensions and long-term development policies.

Published: April 2020

Objetivo. Determinar la relación existente entre el clima escolar y el rendimiento académico en los estudiantes de la Institución Educativa Parroquial San Luis Gonzaga de Huánuco. Métodos. El tipo de estudio fue observacional y trasversal, con enfoque cuantitativo. La población fueron 182 estudiantes, siendo seleccionados 126 estudiantes por un muestreo probabilístico por estratos. Los instrumentos usados fueron la escala de clima social escolar y el reporte de notas del rendimiento académico. Se realizó el análisis descriptivo e inferencial mediante el coeficiente de correlación de Pearson. Resultados. Respecto al clima escolar, se apreció que el 63 % obtiene un resultado “bueno”, el 19 % “regular”, el 14% “deficiente”, el 2 % “muy bueno”, y el 2 % “excelente”. Por su parte, respecto al logro de rendimiento escolar se observó un logro “previsto” (17-14) del 73 %, “en proceso” (13-11) del 16% y “destacado” (20- 18) del 10 %. En definitiva, el clima escolar “bueno” y el logro de rendimiento escolar “previsto” (16-14), se destacan con un mayor porcentaje. Conclusión. La correlación entre el clima escolar y el rendimiento académico fue, por tanto, positiva de nivel moderado. Por lo que se aceptó la hipótesis de investigación

La comprobación de hipótesis fuemediante la prueba de Wilcoxon, considerando un p ≤ 0,05. Resultados. En la prueba de entrada losresultados de la expresión oral fueron similares en ambos grupos, experimental y de control. Despuésde la intervención encontramos que la media del grupo experimental fue de 1,65, mientras que ladel grupo control fue de 0,35; lo que demuestra que los estudiantes del grupo experimental lograronmejores puntuaciones de expresión oral que los del grupo control. Para comprobar si estos valores sonsignificativos, se utilizó la prueba t de Student de independencia obteniendo una p ≤ 0,000; demostrandoque la intervención de talleres experimentales desarrolla las capacidades referentes a la expresión oralen los estudiantes, respecto al grupo que no recibió la intervención. Conclusión. La aplicación del tallerde oralidad influyó en el desarrollo de la expresión oral de la muestra en estudio, por lo que se aceptó lashipótesis de investigación.
Análisis de la aplicación de la teoría cognitiva de Jerome Bruner como mecanismo para fortalecer la conducta ambiental en los estudiantes del Grado Segundo de la Institución
Authors: Rincón Sierra Flor Marina
Published: April 2020

La presente investigación tuvo como objetivo el análisis de la aplicación de la Teoría Cognitiva de Jerome Bruner como mecanismo para fortalecer la conducta ambiental en los estudiantes del grado segundo de la Institución Educativa Chuniza. Para tal efecto se realizó una revisión bibliográfica sobre los aspectos relevantes de la mencionada teoría, así como de los trabajos en ámbito internacional, nacional aun regional, los cuales fueron de gran utilidad para el diseño metodológico, el planteamiento de la estrategia más el análisis de los resultados. El tipo de investigación fue cualitativo con meto Investigación -Acción, el cual partió de una etapa de diagnóstico donde se logró establecer que los estudiantes mencionados requerían fortalecer su conducta ambiental, toda vez que su desconocimiento de conceptos, impacto del hombre sobre la naturaleza la disposición final de residuos sólidos, entre otros, se hizo evidente. Con base en lo anterior, se diseñó una estrategia didáctica utilizando elementos lúdicos, musicales, teatrales incluso poéticos; aspectos que a la postre resultaron muy efectivos, pues se evidenció dinamismo en el desarrollo de cada actividad, análisis inferencial bien crítico de cada situación ambiental en particular y reflexión profunda sobre las causas y consecuencias del fenómeno ambiental actual, así como la creación de compromisos que a la postre servirán como ejemplo para el trato que se dé a tan álgida temática.
