Published: July 2021

Background:

The extensive blowout of COVID-19 globally increases the probability that dental health care professionals will treat this subset of the patient population. If this virus follows the same pattern of other coronavirus infections it is anticipated to indisputably persists as a less virulent infection in our population with milder symptom. Hence, dental students are urged to have thorough knowledge, and keep themselves updated with the practice guidelines regarding this disease.

Aims and Objectives:

To assess the level of knowledge, awareness, and their influence on the attitude concerning the emergent pandemic COVID-19 among postgraduates (PGs), interns, and undergraduate (UG) dental students.

Materials and Methods:

A 21 closed-ended questionnaire was framed with three sections which included knowledge, awareness, and attitude which was face and content validated and circulated in Google form among study participants via various social media forums. Statistical analysis of the data was performed using SPSS (Statistical Package for the Social Sciences) version 20.0.

Results:

A total of 316 responses were obtained in which 11 unfilled or partially filled responses were excluded and 305 responses were included for analysis. PGs had more knowledge, awareness, and attitude than interns, followed by UGs.

Conclusion:

This survey not only recorded the knowledge, awareness, and attitude among the future dental professionals but also acts an indicator of the need for amendments to combat the lacunae especially in the learning dentist population to intensify upcoming dental practice in the post pandemic era.

Published: July 2021

Oral submucous fibrosis (OSF) is an oral potentially malignant disorder characterized by fibroelastic changes in the juxta-epithelial layer leading to trismus. Areca nut and its metabolites contribute to the etiopathogenesis. We report a case of a 53-year-old male patient with burning sensation and reduced mouth opening. Clinical findings and histopathologic findings were consistent with the diagnosis of OSF – intermediate stage. The patient was conservatively managed with lycopene 4 mg twice daily for 3 months and also advised oral physiotherapy. The patient was educated on the effects of areca nut and chances of malignant transformation.

Context:

To improve the success of higher education, various innovative teaching–learning tools are being incorporated by the instructors while planning their classes. This study was carried out to evaluate the impact of anonymous pop-quizzes (APQs) on undergraduate dental students' performance.

Materials and Methods:

A cross-sectional, comparative study was carried out on 20 third-year and 24 final-year dental students. Two different technologies were used to find out the impact of each teaching–learning tool on learning on the same topic “Use of Fluorides in Dentistry” among third-year and final-year BDS students. The first tool was conventional lectures and the second tool used was APQ. One week later, the responses of both the final-year and third-year students were obtained on a ten-question quiz to evaluate the difference in understanding and retention of knowledge of the topic. The data was analyzed using SPSS version 16 software. Descriptive statistics were carried out and an unpaired t-test was applied.

Results:

Average test scores of final-year and third-year students were 41.00 ± 3.81and 34.00 ± 3.83, respectively, which showed a statistically significant difference between the two groups (P = 0.00). Final-year students' feedbacks indicated that the use of APQs improved the knowledge and understanding of the topics and clarified the doubts.

Conclusions:

The use of APQs led to reinforced learning among BDS final-year students.

A review of the anti-viral effects of ivermectin
Authors: Adegboro B. , Lawani O.A. , Oriaifo S.E. , Abayomi S.A.
Published: July 2021

Ivermectin is an avermectin which is a group of pentacyclic sixteen-membered lactone (macrocyclic lactone disaccharide) derived from the soil bacterium Streptomyces avermitilis. It is a semi-synthetic broad-spectrum anti-helminthic, anti-viral and anti-cancer agent. It has a wide safety margin with low adverse effects when it is used orally. It has, however, so far only been approved by the Food and Drug Administration (FDA) as a broad spectrum anti-parasitic agent. Because ivermectin also has broad activities as an anti-viral agent, we herein review its pharmacokinetic and pharmacodynamic activities, as well as the in vitro and in vivo studies conducted on the drug. It is hoped that this work will pave way for ivermectin being seriously considered as an addition to the drugs available for the management of patients with COVID-19.

17th century testaments of the Królik family from Krakow

The article is dedicated to the Królik family from Krakow, who lived in the town from the late 16th century until the first years of the 18th century. The family members initially worked as tailors, later reinforcing the group of Krakow merchants in the third generation (Maciej Królik). Wojciech Królik – from the fourth generation – was a miner in Olkusz. The text omits the most distinguished member of the family, Wojciech’s oldest brother, the Krakow councillor Mikołaj Królik, whose figure has been covered in a separate work. The work shows the complicated religious relations in the family of non-Catholics, initially highly engaged in the life of the Krakow Congregation, but whose members gradually converted from Evangelism to Catholicism. As a result, Wojciech Królik and his siblings became Catholics. This work is complemented by four testaments of family members, with the first, Jakub Królik’s, being written in 1626 and the last one, Wojciech Królik’s, written in 1691.

Catholic contemplative monasteries and the consecrated life in Poland in the context of tourism
Visiting monasteries and staying there have become an attractive tourist experience shared by numerous tourists and perceived by them as truly “touching and authentic”. Not only is a monastery in itself a subject of tourists’ interest with all of its physical attributes, but also the idea and the specific way of life behind it. In the paper, a special attention was paid to the participation of Polish contemplative monasteries in the so-called “monastic tourism”, in order to establish to what extent this phenomenon is close to religious tourism as well as to different forms of cultural tourism meant in the broad sense. Answers to these questions should lie in the results of a survey conducted among the Polish contemplative monasteries preceded by an analysis of motivations and conditions transforming ‘a monastery’ into a tourist destination (external individual attributes such as history and architecture were rejected).

Tourist promotion in the activities of Local Action Groups in Poland The presence of the so-called „Lokalne Grupy Działania” (Local Action Groups, LAGs) has been clearly recognizable in the Polish rural and small-town landscapes for at least a dozen years. By under taking activities on various grounds they obviously support local development, being – at the same time – a source and an effect of local entrepreneurship. According to the principle ”think globally, act locally”, LAGs realize tasks in the field of local tourism development, in terms of tourism facilities, formation of human capital, and tourism promotion. The latter is the goal of the research in this paper. The research resulted in a determination of the broad range of promotional activities and tools used by LAGs. Simultaneously, their effectiveness and the range of influence were evaluated and common good practices in the field of tourism promotion were described. Apart from the generally positive evaluation of tourism promotion provided by LAGs and based on their knowledge on the local tourism potential, specific conditions negatively affecting the durability of results and the period of influence of the promotional message were indicated.

Street art as a source of knowledge about contemporary societies – a proposal of a research method and its verification
The article’s main aim is to present and verify the research approach that can be implemented in street art research in the field of social communication and media science. By focusing analysis on four dimensions – space (where), temporality (when), representation (who) and message (what), it is possible to obtain comprehensive knowledge about key social actors, propagated ideas, postulates and values, and to delineate the main dividing lines, points of reference, icons and symbolic characters. We treat street art as a form of socio-political commentary at the local level, urban space as a channel, and individual manifestations of street art as a medium of communication. The methodological proposal’s usefulness will be verified based on a corpus of 195 photos showing various forms of street art created during the protests in Chile, taken by the Authors in December 2019.

Provider versus navigator. News values and the journalistic professionalism
Authors: Stasiuk-Krajewska Karina
Published: July 2021

The text examines the condition of contemporary journalism in the context of professionalization and values. Presenting the analysis of different ways of defining journalism as a profession, the author notes that contemporary journalism operates within two sets of values. Those that are normally associated with the so-called “professional journalism”, which are referred to the fractographical pact (mainly constituted by such values as: truth, objectivity and independence). The second set of values is called news values. They are fundamentally different and inconsistent with the norms that are considered constitutive for journalism as a profession. In this situation, journalism as a profession and journalists as its representatives are obliged to perform simultaneously two, partly at least contradictory, functions the information provider and the navigator who guides his / her recipients through information for him / her for attractive, noteworthy.
The challenges and opportunities of online learning during Covid-19 pandemic
Authors: Quang Ho Nhut , Tri Ha Minh
Published: July 2021

As the Covid-19 pandemic continues to spread over a year after the original outbreak, it is critical to have an open mind about the innovations higher education institutions (HEIs) have implemented to keep teaching going, as they may help HEIs if appropriately implemented. The pandemic has caused many activities, including traditional educational activities, to be shut down. This has necessitated a vast wave of response migration for HEIs with Online Learning (OL) as the educational platform. This paper conducts desk research to review the challenges and opportunities of OL during Covid-19 pandemic. It was apparent that OL is diﬀerent from emergency remote teaching, and as a result, OL is more justifiable. The unique aspects of the crisis response migration strategies of HEIs, teachers, and learners were discussed. Our findings offer insights for HEIs and especially educational managers, teachers, and learners to be aware of such challenges and opportunities to deal with them.

Development of machine learning methods for spectrum processing is one of the most promising ways for gamma- spectrometry automation and accuracy improvement. Effectiveness of fully connected and convolution neural networks for quantitative γ-spectrometry analysis using scintillation detector NaI(Tl) and lead shielding is presented in the article. Semi-synthetic spectrums were used for the models training; the semi-synthetic spectrums are in channels additions of random spectrums measured at a short duration. The analysis shows advantages of artificial neural networks compare to the common analytical method of spectrum unfolding. The mean square error of activity evaluation is 2–4 times lower than the common method if measuring time is equal to 100 s. In highly standardized conditions of measuring, the advantages of convolution neural networks appear with increasing radiation source activity. Validation with sources not used in training of neural networks has shown fully connected and convolution neural networks can have advantages over the standard method when activity of γ-radiation source is relatively high.

Regulation of water use at industrial enterprises, especially at water-intensive enterprises, in a changing climate is an important economic and environmental task. One of the ways of sustainable water use at enterprises is the constant planning of water consumption and wastewater disposal in relation to the volumes and types of products produced. From a scientific point of view, at water-intensive enterprises, the most reasonable approach to optimizing water use is the development of individual technological standards for water use (water consumption and disposal). Dairy enterprises are quite water- intensive, the water use of which depends on a number of factors: assortment of raw materials for the production of products and types of products; diversification of production processes; the formation and processing of by-products, which often leads to an increase in the volume of wastewater formation in relation to the volume of water consumption; technologies for sanitizing equipment. Taking into account the specifics of production processes, a Methodology for calculating water use for enterprises for the production of dairy products, taking into account the processed raw materials and manufactured products, has been developed. The Methodology substantiates the need to change the terminology in terms of water use rationing, developed criteria for choosing two approaches to the development of individual technological standards for water use, detailed articles of water consumption and water disposal, and clarified certain parameters for their calculation. Approbation of the Methodology showed that the proposed approaches and individual parameters for calculating water use items allow the enterprise to more accurately predict the volumes of water consumption and wastewater disposal when planning production activities, which is especially important for water-intensive industries in conditions of limited available water resources.

Reading Literary Theory between the Lines of Creative Writing: The Dialectics of Theory and Practice in the Creative Writing Pedagogy
Authors:   Department of Greek Philology, Democritus University of Thrace, Greece, Kiosses Spyros
Published: July 2021

Literary theory and critical writing have been traditionally perceived as being in tension, either silently ignoring or polemically rejecting each other. In this paper we argue that literary theory and creative writing are interconnected on various levels. By acknowledging this fact, theory may be profitably deployed in the creative writing class, in order to enhance creative writers’ sense of literary mechanisms, conventions, and purposes in specific sociocultural contexts. In this way, theory informs students not only in relation to the poetics, but also to the pragmatics of the literary phenomenon. Theory askes creative writers to contemplate on how they themselves are socially, ideologically and culturally positioned as writers (and as readers) of literature, and how their activity is enmeshed in a broader process of personal and communal identity formation through language and literary representation.
Evaluating Innovations in Small and Medium Scale Enterprises in Bayelsa State
Authors:   Federal Polytechnics Ekowe, Bayelsa State, Nigeria, Franklin A Agada,
Published: July 2021

Innovation in its modern meaning is "a new idea, creative thoughts, new imaginations in form of device or method". Innovation is often also viewed as the application of better solutions that meet new requirements, unarticulated needs, or existing market needs. Such innovation takes place through the provision of more effective products, processes, services, technologies. The aim of the paper is to give the view on innovation activities in small and medium enterprises (SMEs) sector in Bayelsa state. The paper is divided into two parts. Firstly, the paper is to evaluate situation in innovation activities conducted by small and medium enterprises in Bayelsa state, identifying the main barriers to develop innovation activities, formulate some recommendations on how to overcome these barriers. The second part of the paper is to present the importance of innovativeness, which is viewed as one of the prerequisites for successful innovation activities. Main findings revolve around the facts that product innovations are predominant in SMEs in Bayelsa state and that there is a significant impact of these on growth of firms‟ turnover, profitability and employment generation. And recommended that Prospective entrepreneurs given the resource constraints and weak/unstructured National Innovation Systems (NIS) that characterize developing economies, it makes sense to assume that SMEs therein would focus on incremental innovations and that these would have some positive impact on firm performance and students of entrepreneurship education should be exposed to different innovative schemes, Bayelsa state government should support small and medium enterprises innovation through grants and aid.

Published: July 2021

La genética es un tema especialmente difícil de explicar y de aprender según los expertos por varios motivos, entre ellos el desinterés generalizado del alumnado, así como la naturaleza abstracta y compleja de los procesos moleculares implicados. Con el fin de afrontar dichas dificultades, se diseñó, se implementó y se evaluó una gincana para analizar si permitía consolidar los conocimientos de genética expuestos de manera teórica previamente. El presente trabajo es un estudio de caso de un grupo de alumnos de entre 15-16 años que respondieron un cuestionario test antes y después de realizar la gincana para determinar si esta permite que el alumnado logre los objetivos de aprendizaje para los que fue diseñada. La gincana permite que el alumnado logre la mayoría de los objetivos planteados y por tanto se puede considerar como una actividad centrada en el alumnado y efectiva como actividad de consolidación de los conceptos teóricos sobre genética. Además, tuvo muy buena aceptación y fue bien valorada por parte del alumnado.
Abstract: Genetics is an especially difficult subject to explain and learn according to experts for several reasons, including the general disinterest of students, as well as the abstract and complex nature of the molecular processes involved. To face these difficulties, a gymkhana was designed, implemented and evaluated to analyze whether it allowed to consolidate the knowledge of genetics previously exposed in a theoretical way. The present work is a case study of a group of students aged 15-16 who answered a test questionnaire before and after performing the gymkhana to determine if it allows students to achieve the learning objectives for which it was designed. The gymkhana allows students to achieve most of the objectives set and therefore can be considered as an activity focused on students and effective as an activity for the consolidation of theoretical concepts on genetics. In addition, it had a very good acceptance and was well valued by the students.
Increasing the Photovoltaic Hosting Capacity in Autonomous Grids and Microgrids via Enhanced Priority-List Schemes and Storage
Authors: Nikolaidis Pavlos , Poullikkas Andreas
Published: July 2021

European Union has seen a rapid increase in renewable energy sources during the last decade. The variability and uncertainty caused by the increased penetrations of renewable generation must be properly considered in day-ahead unit commitment to retain the stable operation of conventional power plants. In this work, we present an enhanced method to determine the hosting capacity of photovoltaic energy in an autonomous grid. Based on optimal unit commitment schedules derived from priority list-schemes, we examine the potential of increasing the hosting capacity performing annual simulations for different scenarios in the presence of electricity storage. According to the obtained results, the application of storage eliminates the reliability expenses of load shedding and spinning reserve deficits. Hence, the actual hosting capacity is appropriately retrieved based on the renewable generation curtailment during each case study. However, sustainable solutions are achieved at higher penetration levels, reaching a near of 20% with respect to photovoltaic systems. The proposed solution could be efficiently utilized to determine the photovoltaic hosting capacity of microgrids in islanded or interconnected mode.

To ensure energy security, reduce greenhouse gas emissions and increase agricultural output, the Vietnamese government has issued several policies to promote gasohol, resulting in remarkable achievements in gasohol development in recent years. However, unexpected limitations have been seen by other countries after a period of using this fuel such as air pollution, threats to food security, deterioration of natural forest area and severely depleted freshwater resources. This paper presents an overview of the current state of Vietnam's gasohol market and a brief analysis of policy, supply - demand - price information, from which some hindrances are identified and a few more optimistic directions to develop this type of fuel in the future are proposed.

Con el objeto de evaluar el uso del suero lácteo en la suplementación de becerros lactantes y su efecto sobre la ganancia de peso, consumo y costo de crianza, se realizó un ensayo con diseño completamente al azar. Se utilizaron 25 becerros de la cruza Suizo/Americano – Cebú/Holstein entre 8 y 12 semanas de vida; que fueron asignados, bajo un diseño completamente aleatorio en cinco tratamientos experimentales de cinco animales cada uno; T1: 4.5 L. de suero lácteo + 1.5 L. de sustituto/día + 250 gr. de concentrado; T2 : 5.0 L. de suero lácteo + 1 L. de sustituto/día + 250 gr. de concentrado; T3: 5.5 L. de suero lácteo + 0.5 L. de sustituto/día + 250 gr. de concentrado; T4 : 6 L. de suero lácteo / día + 250 gr. de concentrado; T5 : 6 L. de sustituto/día. El concentrado ofrecido tuvo un 20% de proteína cruda. La duración del ensayo fue de 90 días, observándose los siguientes resultados para T1, T2 , T3, T4, T5 respectivamente: Se presentaron diferencias significativas (P<0.05), tanto para la ganancia diaria de peso 610, 417, 436, 565 y 386 g/animal, como en la incidencia de diarreas 4%, 12%, 4%, 4%, 20%, el análisis económico arrojó que es factible utilizar el T4 tomando en cuenta que el precio del suero es de $0.30/kg, de esta manera el ingreso bruto se verá incrementado y por ende la relación costo/beneficio.

Con el propósito de evaluar el valor nutritivo del maíz henificado, como alternativa al ensilaje en explotaciones de bajos recursos se efectuó un estudio en dos localidades del estado de San Luis Potosí. En cada localidad se estableció una parcela de maíz de la variedad H-311 en condiciones de temporal. Se cosecharon plantas completas cuando el grano se encontró en estado masoso-lechoso, la mitad de ellas se ensilaron y la otra se henificaron. De cada lote de forraje se envió una muestra representativa al laboratorio para determinar proteína cruda (PC), Fibra Detergente Acido (FDA) y digestibilidad in situ de la materia seca. Los resultados de valor nutritivo del ensilaje y heno de la primer localidad muestran que el contenido de FDA y de PC fue similar en los dos tipos de forrajes, pero la digestibilidad in situ fue mayor (P=0.008) en el ensilaje. En la segunda localidad los resultados muestran que el contenido de FDA fue menor (P=0.023) en el heno, mientras que la PC fue similar (P=0.083) en los dos tipos de forraje, aunque con tendencia a ser más elevada en el ensilaje. La digestibilidad in situ fue mayor (P<0.0001) en el heno. Los resultados de este estudio sugieren que aunque podría haber diferencias en la digestibilidad, esta no es contundente, debido a que en un experimento el ensilaje mostró mejor digestibilidad, mientras que en el segundo, el heno fue mejor. Se concluye que el henificado de maíz, al ser un método económico para conservar el forraje de maíz, representa una opción accesible para ser utilizado por ganaderos de bajos recursos para contar con forraje de calidad para las épocas críticas.

Se presenta una contribución de la diversidad de epifítas vasculares del ANP Sierra de Otontepec, en tres tipos de vegetación: bosque mesófilo de montaña, bosque tropical perennifolio y acahual, en los municipios de Chontla y Citlaltepetl. Se encontró que este grupo de plantas está representado principalmente por las familias Bromeliaceae (26.4%) y Polypodiaceae (23.5 %), seguido de la familia Orchidaceae y Piperacea (14.7%). El BMM presento mayor riqueza de especies (46%), mientras que el BTP presento menor riqueza (23%) en comparación con el AC (31%). Se registraron dos especies en la NOM-059-SEMARNAT-2010, en la categoría de Amenazadas (Tillandsia imperialis y Prostecheae mariae). Este grupo de plantas se ven afectadas por la fragmentación y recolección ilegal, por lo que, se considera necesario generar conocimiento sobre las especies que se encuentran en la reserva.

La presencia reciente del Pterygoplichthys, comúnmente conocidos como plecos, pez diablo o limpia peceras, en las aguas epicontinentales de la zona de Chinameca, Veracruz, se ha convertido en un problema ecológico y ambiental, debido a que por su enorme plasticidad adaptativa y a la ausencia de depredadores naturales, provoca desplazamiento de especies nativas. Actualmente en el estado de Veracruz no se cuenta con trabajos de investigación que permitan sustentar medidas de control y/o erradicación del Pterygoplichthys. Con el objetivo de obtener datos básicos del Pterygoplichthys, se llevaron a cabo muestreos biológicos bimestrales, sobre la parte baja del río Chacalapa y la represa artesanal adyacente denominada “La Chinampita”. Los muestreos iniciaron en el mes de julio de 2012 y culminaron en mayo de 2013, se realizaron con artes de pesca poco selectivos. Se determinó la presencia de la especie P. pardalis, con individuos de 420 mm de longitud total (LT) y un peso de 620 g en los machos, en las hembras fue de 390 mm LT y 650 g. Los registros de captura que mayor abundancia de plecos presentaron, fueron en el mes de mayo con el 43%. A partir del mes de marzo se registró el inicio de la actividad reproductiva, con máximo desarrollo gonadal en mayo.

El objetivo fue determinar el efecto de la aplicación intramuscular de oxitocina para inducir la eyección de leche en indicadores de estrés y temperatura rectal en vacas ordeñadas mecánicamente en el trópico veracruzano. Se utilizaron vacas cruzadas (n=96) Suizo Americano-Cebú y Holstein-Cebú ordeñadas 2 veces al día. Las vacas después del parto se asignaron aleatoriamente de acuerdo al numero de partos a recibir 10 UI de oxitocina intramuscularmente (n=56) o NO ser inyectadas (n=40) al ordeñarlas. Durante el ordeño se observaron las siguientes variables: pisoteo, pateo, movimiento de la cola, dejar de comer, si se movió bruscamente y después del ordeño se tomó la temperatura rectal (TR). El análisis estadístico se realizó utilizando ANOVA y ji-cuadrada del software statistica 7. Las vacas inyectadas con oxitocina tuvieron un mayor (P=.05) porcentaje de animales que pisotearon y patearon (53%), dejaron de comer (61%), movieron la cola (71.4%) y se movieron (71.5%) comparadas con las vacas no inyectadas (10%, 0%, 3%, 3%, 6%, respectivamente). Las vacas inyectadas con oxitocina tuvieron una mayor temperatura rectal (39.13±.08 oC) y numero de pisoteos (2.62±.36) comparado con las vacas no inyectadas (38.96±.12 oC y .24±.54; respectivamente). En conclusión, las vacas inyectadas con oxitocina manifestaron elevados indicadores de estrés y temperatura rectal comparados con los de las vacas no inyectadas, sugiriendo que si existe una reacción de las vacas inyectadas intramusculares y rutinariamente con oxitocina y estas no se habitúan a la inyección.

En el presente trabajo se muestra la forma de optimizar el método de preservación por inmersión del bambú en la región de de Cuetzalan del Progreso Puebla. La investigación se llevo a cabo en el taller de bambú en la sociedad cooperativa Tosepan ojtasentekitini ubicada en el Municipio de Cuetzalan del Estado de Puebla. Tiene como propósito principal el de recomendar la cantidad ideal de solución en el tiempo adecuado de inmersión para su preservación. Se realizo un diseño experimental completamente al azar con 2 factores. Tomando 12 repeticiones para cada tratamiento, con tres especies Guadua aculeata, Bambusa oldhamii, Guadua angustifolia. El preservante utilizado consistió en una mezcla de compuestos de boro, bórax (Na2B4O710H2O) y ácido bórico (H3BO3) en proporción 1:1. Los principales resultados de la investigación realizada, se encontró que para la especie Guadua aculeata se puede disminuir la concentración utilizada actualmente al 50 % manteniendo los culmos en 4 días de inmersión ya que no existe una variación estadística significativa en relación con mayor concentración o mayor número de días en inmersión por lo tanto es posible optimizar gastos y tiempo al realizar el tratamiento preservante.
