El rol y las aplicaciones de las enzimas fúngicas que degradan los desechos agrícolas
Authors: Ravanal M. C. , Ulloa P. E. , Chávez R.
Published: July 2022

Los desechos agrícolas son una excelente fuente de materia orgánica renovable y su principal compuesto es la lignocelulosa formada por lignina, pectina, celulosa y hemicelulosas. El xilano es el principal componente de las hemicelulosas y es el segundo polisacárido renovable natural más abundante disponible en la tierra. Es un heteropolisacárido complejo formado por diferentes monosacáridos como D-xilosa, L-arabinosa, D-galactosa, D-manosa y ácidos orgánicos como ácido acético, ácido ferúlico, ácido glucurónico entrelazados con la ayuda de enlaces éster y glicosídico. La biodegradación del xilano es un proceso complejo que necesita la participación de una serie de esterasas y glicosil hidrolasa. La idoneidad de las glicosil hidrolasa para su aplicación en papel y pulpa, alimentos, biorrefinería ha llevado a un aumento en la demanda de estas enzimas a nivel mundial. La presente revisión da una idea de la bioquímica y el uso de las glicosil hidrolasas fúngicas en la industria como una herramienta ecológica emergente.

Rating Prediction based on Optimal Review Topics: A Proposed Latent Factors-Optimal Topics Hybrid Approach
Authors: Chambua James
Published: July 2022

Rating prediction is an inevitable problem which recommender systems (RS) need to address. Its goal is to accurately predict the rating a user will assign to a particular item. Predictions which utilize numerical ratings and review texts are biased and have low accuracy. Also, existing topic-based rating prediction approaches focus on finding the most preferred items through the identification of latent topics expressed in users’ review texts. Even though the latent topics seem to represent most user review texts, they do not necessarily capture each user’s preferences. The goal of this work is then to develop a more accurate model by considering product review texts analysis so as to gain additional preference knowledge. Hence, a hybrid algorithm that optimizes the latent topics is proposed.  Specifically, the proposed approach finds appropriate weights for the topics of each review text. Rating prediction is critical task for RS because slight performance enhancement of the prediction accuracy results into significant improvements in recommendations. Experimental evaluation over real-world datasets revealed performance improvements of the proposed approach compared to alternative models. The proposed model can be used by RS in various domain such as e-learning, movie and hotel rating.
The Influence of Organizational Justice on the Organizational Commitment of Personnel in South-West Nigerian Public University Libraries
Authors: Adewoyin Omobola Olufunke
Published: July 2022

For university libraries to achieve their set goals and objectives, a committed workforce is indispensable. Several factors could enhance the commitment of library personnel. However, studies have not given adequate attention to the influence of organizational justice on the organizational commitment of library personnel in Nigeria. This study, therefore, investigated the influence of organizational justice on the organizational commitment of library personnel in public universities in South-West Nigeria. A survey research design was adopted. A total remuneration was used. Findings showed that organizational justice had a significant influence on organizational commitment of library personnel. The findings also revealed that distributive justice and interactional justice significantly influenced the affective commitment of library personnel while procedural justice was not significant. Furthermore, distributive justice and interactional justice had a significant influence on the continuance commitment of library personnel while procedural justice had no significant effect on the continuance commitment of library personnel. The study concluded that organizational justice increased organizational commitment of library personnel in public universities. The study would serve as a contribution towards solving the challenges of lack of organizational commitment in academic libraries. It was recommended that library management should involve the personnel in their decision-making processes.
Sentiment Analysis of COVID data extracted via Twitter
Authors: Rugved Mone and Bhakti Palkar
Published: July 2022

Different types of social media sites exist, wherein some of them are LinkedIn, Twitter, Facebook, Instagram, WhatsApp, etc.
As the number of social media users increases, the opportunity for the user to express their feelings also increases. Twitter is a
choice of many users as it not only allows the users to express their thoughts but to interact with official accounts (PMO, Defense
Ministry) which can be seen with a verified tick on the website.
In this thesis titled ‘Sentiment Analysis of COVID data extracted via Twitter’, multiple machine learning and deep learning
techniques have been researched and implemented to perform sentiment analysis. Moreover, a novel approach using deep learning
architecture has been proposed. It is based on a combination of Bidirectional Long Short Term (BiLSTM) neural networks and
Convolution Neural Networks (CNN). Prior to implementing the algorithms, the data is acquired by using web-scraping
techniques and/or public APIs pertaining to Twitter. A comparative analysis of the efficiency and performance of the proposed
technique along with other existing approaches discovered during the literature review phase is also presented.

Authors: Álvarez Carmen D. , Tierno Sandra Pilar
Published: July 2022

En este trabajo se ha analizado el concepto de salud y su representación en 43 libros de texto de Educación Primaria de la Comunidad Valenciana, suponiendo la actualización local de un análisis previo realizado en 2003. Además de la descripción de las variables bibliométricas, se han extraído los temas de salud abordados en cada libro y su metodología, analizando su correlación con el curso y ciclo. Los resultados muestran que sigue ofreciéndose el concepto de salud como ausencia de enfermedades. Asimismo, las metodologías de mayor complejidad aparecen en los manuales de los cursos inferiores de primaria. En consecuencia, estos resultados indican la necesidad de realizar acciones claras y directas para dotar al profesorado de recursos eficientes para complementar lo ofrecido en los libros de texto.

Authors: Hirsch-Adler Ana , Izarra Vielma Douglas A
Published: July 2022

La formación de investigadores es un proceso complejo en el que se relacionan múltiples elementos. La forma como se organiza la enseñanza es uno de los más relevantes. Se planteó como objetivo analizar las estrategias que los profesores de posgrado de una universidad mexicana desarrollan para la preparación de sus estudiantes en investigación. Se realizó una revisión de diversas publicaciones sobre esta temática y para recolectar información empírica se empleó una metodología cualitativa, con base en 34 entrevistas, que son parte de una muestra de académicos de posgrado que fueron reconocidos como excelentes por sus pares. La pregunta que se empleó es: ¿Qué estrategias utiliza para lograr en la docencia los mejores resultados para atender las necesidades de los alumnos? que pertenece a una guía de entrevista que se aplicó en 2017 y 2018. A partir del análisis y como resultado se construyeron ocho categorías que dan cuenta de los diversos procedimientos utilizados por los académicos entrevistados. Como conclusión encontramos que no existe un camino único para formar investigadores, pues las estrategias se superponen e integran unas con otras en el desarrollo del proceso de enseñanza y se ajustan a las necesidades tanto de los profesores como de los alumnos.

Recirculation aquaculture systems require proper food management, and feeding frequency is one of the most important factors to obtain optimal results in production. The tambaqui Colossoma macropomum presents satisfactory zootechnical performance in Pará State, but research related to its food management in recirculation aquaculture systems are scarce, in view of this, this work aimed to evaluate the zootechnical performance of tambaqui juveniles raised in Recirculation aquaculture systems. A total of 324 tambaqui juveniles with an average initial weight of 24.7 g were used in a recirculation system with three treatments in triplicate, with fish fed two, three and four times a day. The fish were fed with commercial ration with 32 and 36% of crude protein for 40 days and with a feeding rate of 4%. During the experiment were measured: temperature; pH; dissolved oxygen; pH; conductivity; turbidity; salinity, dissolved solids and nitrogen compounds of the system water, and these had a low variation between treatments. The fish fed with higher frequencies had higher final average weight and higher specific growth rate, with this, from the results obtained, it is concluded that the best feeding frequency for tambaqui juveniles is three times a day.
Commodification of Women and Female Struggle for Power in Thackeray’s „Vanity Fair“
Authors:   University of Priština in Kosovska Mitrovica, Faculty of Philosophy, Ninčetović Nataša V.
Published: July 2022

Indoctrination of women in Great Britain reached its peak during the Victorian age. The embodiment of this peak is the phenomenon of separate spheres. The Victorian culture categorized women as either Angels in the House or fallen women. These moulds were reflected in the Victorian novel. In contrast to common categorization of women, Thackeray makes an effort in Vanity Fair to represent real women, women who do not fit into prescribed types and definitions. This research attempts to prove that both Becky and Amelia are aware of their inferior position. Both of them do what they consider socially acceptable. Their identities are performed, but Amelia’s performance passes as natural, whereas Becky’s acting is recognized. They succeed to dominate men they get in touch with. While Amelia marries Dobbin, morally the most prominent character of the novel, Becky’s triumph is short-lived. One of the main causes of the moral crises of the Victorian era is society’s attitude toward women. Thackeray suggests that only a radical change in beliefs will lead to their better position.
Empatija kao razvojni zadatak u „Parcifalu“ Volframa fon Ešenbaha
Authors:   University of Niš, Faculty of Philosophy, Ognjanović Branka B.
Published: July 2022

The paper presents an overview of the existing interpretations of the key de- velopmental task of the protagonist in the medieval novel Parzival by Wolfram von Eschenbach, namely, the awakening of empathy and asking the right question to the Grail keeper. The goal of the paper is to emphasize the importance of empathy for Parzival’s development from naivete (tumpheit) and overall ignorance regarding the social conventions of the knightly society in the High Middle Ages to potential maturity and wisdom (wīsheit), which could be part of an inner, authentic process of growth, but also a consequence of mere obedience. The analysis contains firstly the definitions of the term empathy, which can be understood as a psychological term as well as one of the virtues within the knightly system of virtues (ritterliches Tugendsystem), secondly the examination of Parzival’s childhood and education and his relationship to different role models and teachers as a source of his naivete and lack of compassion, and finally the inter- pretation of the key scenes in the Grail castle Munsalvaesche and his development of empathy, personal growth and the ability to become part of the knightly society.

Published: July 2022

Epithelioid sarcoma is an uncommon kind of sarcoma that often affects young individuals and has a preference for distal upper extremity; forearm and hand. This usually begins as slow-growing, painless tumor. It can also be seen as multiple tumours. Lymphatic channels are the primary routes of dissemination for the disease’s recurrence and spread. Using polygonal cells, a biopsy is the preferred technique of diagnosis. Treatment primarily consists of wide resection.
Here, we present a case of epithelioid sarcoma involving the wrist of 52-years old female. It was initially diagnosed by imprint cytology. To make an accurate diagnosis in a case with a unique history, it is necessary to consider the clinical presentation, morphologic examination, and a broad panel of immunohistochemical staining.

Authors: Herrera-Flores Boris , Benavides-Morales Cristina
Published: July 2022

En diciembre de 2019 la vida nos cambió para siempre. La emergencia sanitaria ocasionada por el COVID 19 obligó a los gobiernos del mundo a decretar normas de aislamiento obligatorio para sus ciudadanos, las medidas modificaron las dinámicas socioculturales, económicas, laborales, y de manera particular la interacción social. Una de las principales consecuencias fue el cierre de establecimientos educativos y la adopción de una modalidad mediada por herramientas tecnológicas a la que denominaremos educación remota de emergencia. El estudio analiza la percepción de los estudiantes de la Carrera de Comunicación Social de la Universidad Central del Ecuador en el período académico extraordinario (junio - septiembre 2020). Se analizó la aplicación de la normativa institucional para el aprendizaje remoto, la transformación de las prácticas educativas: clases magistrales, tutorías y evaluaciones en un entorno completamente digital, y la interacción docente/estudiante en el nuevo escenario.  En el procesamiento global del texto se identificó una tendencia del estudiante a expresar su opinión cuando colocaba una calificación cuantitativa negativa, como una reacción natural para expresar sentimientos de queja, inconformidad y demanda de atención, cuando la valoración era positiva no comentaban.
Detección de Mycoplasma hominis y Ureaplasma urealyticum en parejas con infertilidad
Authors: Ávila Jaime Paz , Escobedo Raúl de León , Cárdenas José Eugenio Guerra , Pérez Brian González , Beltrán Elizabeth Reyna , García Josefina Altamira
Published: July 2022

INTRODUCCIÓN: La infertilidad, descrita como la incapacidad de conseguir la concepción después de mantener relaciones sexuales de forma regular, en ausencia de anticoncepción durante un año, es un problema de salud pública que afecta alrededor del 10 % de las parejas en todo el mundo. Algunos microorganismos responsables de infecciones urogenitales, tanto en hombres como en mujeres, se han asociado a infertilidad. Los micoplasmas son considerados flora normal; sin embargo, Mycoplasma hominis y Ureaplasma urealyticum, miembros de una clase única de microorganismos son patógenos oportunistas; en consecuencia, el diagnóstico y tratamiento inoportuno puede disminuir la probabilidad de una gestación exitosa. OBJETIVO: La presente revisión muestra un análisis de los métodos de detección actuales, para Mycoplasma hominis y Ureaplasma urealyticum, en el contexto de la evaluación de la infertilidade. MÉTODOS: Se ejecutó una búsqueda selectiva, en las colecciones de publicaciones biomédicas digitales Pubmed-Medline, Scopus, Web of Science, LILACS, Cochrane, SIGN y NICE, de artículos publicados en idioma español o inglés, entre enero de 2010 y agosto de 2020, limitado a estudios en seres humanos adultos, utilizando los encabezados de materia médica (MeSH, por sus siglas en inglés) o los descriptores de ciencias de la salud (DeCS) de la Organización Panamericana de la Salud: "Ureaplasma Infections|diagnosis", “Ureaplasma urealyticum”, "Mycoplasma Infections|diagnosis”, “Mycoplasma hominis”, "Infertility, Female”, “Infertility, Male” y sus equivalentes en español. RESULTADOS: Se documentó que los métodos moleculares, particularmente las reacciones de la cadena de la polimerasa (PCR) múltiples o multiplex, presentan mayor sensibilidad, especificidad, reproducibilidad y practicidad. No obstante, la especialización técnica y la infraestructura requerida para desarrollarlas no están disponibles en la mayoría de los laboratorios clínicos, principalmente en aquellos cuyo volumen de trabajo es bajo, manteniendo a los cultivos como métodos de detección de referencia, aunado a la evaluación de la sensibilidad antimicrobiana. Actualmente, con el desarrollo de diferentes técnicas de tipificación molecular, la identificación de «patotipos», o grupos de virulencia, podría convertirse en un requerimiento diagnóstico indispensable. CONCLUSIONES: Las técnicas de detección que utilizan antígenos o anticuerpos específicos presentan una alternativa para mejorar la precisión diagnóstica a un costo razonable; sin embargo no son utilizadas.

Published: July 2022

Ülkemizde yüksek hızlı tren yolcu taşımacılığının trafik akış hızı maksimum 255 km/h değerine ulaşacak şekilde faaliyete geçmiştir. Söz konusu gelişmeye bağlı olarak demiryolu trafiği kaynaklı titreşim sorunlarının güzergâh boyunca öngörülememesi, mevcut araştırmaların sadece ray titreşimleri ve gürültü kirliliğinin azaltılmasına odaklanmış olması, yapılan bu çalışmayı çevresel titreşim etkilerinin sahada yerinde ölçülerek tespit edilmesine yönlendirmiştir. Yapılan bu çalışmayla, yolcu taşımacılığında kullanılan yüksek hızlı tren (YHT) geçişlerinin ölçüm sahasının değişen zemin koşullarında oluşturduğu yüzey titreşim dalgalarının yayılma biçimleri araştırılmıştır. Elde edilen deneysel ve nümerik sonuçlara bağlı olarak, YHT trenlerinin alüvyon zeminlerde oluşturduğu en büyük titreşim değerlerinin uzaklığa bağlı değişimi incelendiğinde Bornitz analitik çözümünün orantılı değişim gösterdiği ancak bu durumun deneysel ölçümler için geçerli olmadığı anlaşılmıştır. Hendekli ve hendeksiz test sahasında yapılan titreşim ölçümleri ve bu ölçümlere ait elde edilen bulguların ortaya koyduğu sonuçlar doğrultusunda hendek varlığının hızlı tren kaynaklı titreşimleri önemli oranda azalttığı söylenebilinir. Ayrıca çalışma sahasına sonradan döşenen beton parke kilit taşı özellikle demiryolu hattına yakın ölçüm noktalarındaki hızlı tren kaynaklı titreşimler üzerinde hendeğin dışında önemli oranda yalıtım etkisi göstermiştir. Çalışma kapsamında kaydedilen ölçüm sonuçlarının güvenirliliğini test etmek amacıyla mesafeye bağlı olarak regresyon analizi yapılmış ve analitik yönteme ait azalım eğrileri ile karşılaştırılmıştır. Demiryolu kaynaklı titreşimlere ait regresyon analiz sonuçlarının yüksek korelasyonlu olması kullanılan analiz yönteminin geçerliliğini göstermiştir.

This research is a type of Classroom Action Research (CAR) which aims to improve the quality of the teaching and learning process which leads to an increase in student activity and student result in Basic Electrical and Electronics subjects. The design of classroom action in this study refers to the design of Kemmis & Taggart model which consist of several cycles and each cycle there are four stages, namely (1) planning stage, (2) action stage, (3) observation stage, and (4) reflection stage. The population of this study were students of class X TOI in the Industrial Automation Engineering Expertise Program at SMK YPWKS Cilegon, the samples in this study were students of class X TOI A as many as 22 people. Data were collected through tests and observations. Technical analysis of data using descriptive quantitative. The results showed that the application of Group Investigation learning model in Basic Electrical and Electronics subjects could increase the student activity and student result of class X TOI A students. This increase in activity can be seen from student contribution during the learning process in the form of student enthusiasm in paying attention to teacher explanations, paying attention to friends' explanations while presentations, asking question, expressing opinions,  taking notes on material, writing assignments given by the teacher, and working together with groups. The highest achievement in the indicator is paying attention to the teacher’s explanation, taking notes and listening to the teacher’s explanation, each indicator has a percentage of 95,45%. Meanwhile, the lowest achievement is the indicator of doing group work and listening to questions and answers with a percentage of 72.73%. The increase in student learning activity has an effect on increasing students' psychomotor and cognitive learning outcomes. The average value of psychomotor learning outcomes in the first cycle was 67.73%, increasing to 81.82% in the second cycle. The students' cognitive aspect obtained the percentage of the first cycle of 74.06% and the second cycle increased to 69.32%. And increased in the second cycle that is equal to 82.27

Introduction. Innovative low-volume technologies for soilless cultivation of vegetable crops are changing the nature and working conditions of workers, contributing to their transition to a qualitatively new level of health safety. However, modern aspects of the formation of the health of greenhouse workers remain insufficiently studied. Material and methods. Comprehensive studies of working conditions and morbidity (general, primary, accumulated, nosological structure and its dynamics) were carried out according to periodic medical examinations (2013-2017) of greenhouse vegetable growers working under the conditions of using innovative technologies for soilless cultivation of vegetable crops. Results. Working conditions of modern greenhouse vegetable growing were shown to remain unfavourable. They not meet the hygienic standards for the content of chemicals and aerosols of predominantly fibrogenic action (APFD) in the air of the working area, the parameters of the microclimate and the severity of the labour process, forming harmful working conditions (class 3.3), representing high risk to the health of workers. The overall incidence of vegetable growers in different years of observation ranged from 845.6 to 1129.0‰ with the frequency of detection of incidence in the range of 181.8-231.9‰. The first ranking places in the nosological structure of general morbidity were occupied by diseases of the circulatory system (Essential (primary) hypertension), genitourinary (Benign mammary dysplasia) and musculoskeletal systems (Dorsalgia of the lumbosacral and cervical levels). Limitations. The boundaries of the study are determined by studying the prevalence of diseases detected during periodic medical examinations among workers in protected ground in the vegetable grower profession and by studying the production factors that cause their occurrence. Conclusion. Working conditions in greenhouse vegetable growing continue to be harmful, presenting a risk of development and progression of chronic general somatic diseases among workers, which indicates the need for further research, including the identification of statistical patterns between indicators of the levels of exposure to factors and the likelihood of negative changes in health status.

Introduction. Pathologies of the musculoskeletal system have been occupying the leading place in morbidity among schoolchildren for a long time. Our research aim was to examine peculiarities of developing postural disorders in schoolchildren from different age groups. Materials and methods. We examined seventy two primary schoolchildren (their average age was 8.19±0.32 years); 87 middle schoolchildren (12.94±0.24 years); and 54 senior schoolchildren (16.65±0.21 years). These test groups were comparable for gender and social background. The health of the musculoskeletal system was assessed on the base on data of a medical examination and results by laboratory tests (phosphor-calcium metabolism); postural disorders were examined as per surfaces with a computer optical topographer; bone mineral density was determined by ultrasound osteodensitometry; body composition was assessed with bioimpedance analysis (BIA). Results. Pathologies of the musculoskeletal system were detected in 77-83.3% schoolchildren. Each second child in primary and middle school had deforming dorsopathy and each second senior school student had scoliosis. We established a probability of developing scoliosis to be by 5.9 times higher in senior school. Children in primary school predominantly had twisting postural disorders (28.4%) and swayback (11.1%) accompanied with the lower phase angle, a lower share of active muscle mass detected with BIA and osteopenia developing in ¼ cases. 16.1-26.1% of middle schoolchildren had twisting postural disorders and kyphosis, 57.9% children in this age group had lower contents of ionized calcium in blood, 28% had osteopenia and a decrease in fat-free mass detected with BIA. Scoliosis in senior schoolchildren (51.9%) and kyphotic-lordotic back (24.1%) were accompanied with lower contents of phosphor and alkaline phosphatase, developing apparent osteopenia (18.4%) and lower mineral mass. We established the probability of postural disorders developing in three surfaces to be 3.3 times higher among teenagers in senior school. Limitations. The results of the studies can only be extrapolated to the population of 7-17 years children of both genders. Conclusion. We revealed certain peculiarities of developing postural disorders in schoolchildren. They can be used in implementing health-preserving technologies in schools as well as in developing new hygienic and organizational approaches to the conditions of the educational process in schools.
