Authors: Dávila Navarro Edgar , Portugal Rigliana
Published: April 2022

El estudio tiene por objetivo identificar el acceso, uso y comprensión crítica de mensajes violentos en televisión y smartphones, que hacen niñas de 10 a 14 años y mujeres jóvenes de 20 a 29 años, durante agosto de 2018, en dos zonas de la ciudad de La Paz: Max Paredes y Periférica. El enfoque metodológico de la investigación es cuantitativo, con un diseño descriptivo y comparativo, que aplica una encuesta a través de un cuestionario administrado a 403 mujeres (272 jóvenes y 131 niñas). La investigación concluye que 6 de cada 10 niñas y 5 de cada 10 jóvenes acceden y usan la televisión entre 2 a más de 3 horas. En el caso de los smartphones, este acceso y uso sube a 6 de cada 10 niñas y a 7 de cada 10 jóvenes. Ambos grupos de estudio consideran que estos medios las distraen (5 de cada 10 niñas y jóvenes). 67,2% niñas y 59,8% jóvenes vinculan la violencia a un conjunto de acciones que provocan daño físico. A nivel de comprensión crítica, las niñas identifican a la violencia física como la más frecuente en televisión (49,6%); mientras que las jóvenes consideran la violencia sexual como la más recurrente (43,5%).
La substancia que quiere y que cree Roger Pouivet: de la Epistemología de la virtud al virtuosismo estético. Propuesta de una forma distinta de afrontar la estética y su valorización
Authors: Iriarte Rico Gabriel
Published: April 2022

La presente exposición se basa en el pensamiento de Roger Pouivet y su estudio sobre la epistemología de la virtud. Pongo énfasis en ese “se basa” pues lo que hago y a veces fuerzo para darle un sentido, es utilizar este pensamiento para interpretar nuestra realidad con lo que creemos que es arte. Creo que esta adaptación tiene el fin de aportar una visión más que no busca ser absoluta, solo aportar justicia al análisis estético.
Las comunidades virtuales del quichua ecuatoriano: revalorizando la lengua en un espacio apropiado
Authors: Garcés Velásquez Fernando
Published: April 2022

Las lenguas indígenas de América tie- nen una larga historia de subalterniza- ción que se mantiene hasta el día de hoy. Por esta razón, las Naciones Uni- das declararon el 2019 como el Año In- ternacional de las Lenguas Indígenas, como un esfuerzo de revertir el proce- so de pérdida de la diversidad lingüís- tica del planeta. El quichua ecuato- riano es una lengua con presencia en varios países de la región. En Ecuador es la lengua indígena con mayor nú- mero de hablantes; sin embargo, hay evidencias de encontrarse en dramá- tica situación de retroceso en cuanto a la trasmisión intergeneracional. En el contexto actual, los jóvenes quichua hablantes se apropian de recursos tec- nológicos para la construcción de co- munidades virtuales de defensa y di- fusión de la lengua y cultura quichua. En esta comunicación se presenta una investigación de carácter explorato- rio de dos comunidades virtuales en el Facebook: Kichwa Mashikuna y Ki- chwa Hatari NY. A partir de este acer- camiento se postula la necesidad de pensar la supervivencia lingüística de cara a la posibilidad de adaptación al contexto urbano y tecnológico. Y en este sentido, los jóvenes quichuas apuestan a “atravesar la modernidad”, antes que rodearla o negarla.
Las Condenadas. Violencia hacia mujeres en chicherías y lugares solitarios en Cochabamba a inicios del Siglo XIX
Authors: Sotéz Gómez Dyann
Published: April 2022

Pese a que los estados latinoamericanos han implementado leyes que apuntan a combatir las violencias hacia las mujeres, éstas han sido de poca efectividad. Esto aún es un problema estructural, y a la vez, histórico. En ese sentido, el presente artículo tiene por objetivo explicar las violencias hacia las mujeres y los lugares donde se ejercían en la sociedad cochabambina a inicios del siglo XIX. Para ello, se utilizó el método histórico que consiste en el análisis de documentos históricos denominados expedientes republicanos de los años 1825 – 1855, que se encuentran en el Archivo Departamental “José Macedonio Urquidi”.

Published: April 2022

Long-range (LoRa) technology is vastly developing in a significant country that evolves around the Internet of Things (IoT) interest. Such IoT accomplishments include the development of smart cities, long-range monitoring systems, and M2M industries. LoRa technology is making its mark in vehicle-to-vehicle (V2V) communications, but it is yet to be fully explored. This study focused on developing and establishing communication between two LoRa powered devices and evaluating their performances upon deploying a prototype in an actual environment. The prototype is designed with bidirectional communication between two LoRa nodes that could exchange data for user references. Moreover, in the context of having V2V communication, speed and distance are involved in determining the exchange of data. The performance is evaluated in terms of data transmission consistency and reliability. The experimental results revealed that LoRa is applicable for V2V communication within a specific condition; however, there is a need for a more extensive experiment to be carried for a major rolled out of deployment.

Authors: Meesaard Napaporn , Nathapindhu Ganjana
Published: April 2022

Tire manufacturer workers who work in hot environments in the workplace may suffer a variety of heat-related symptoms. The purpose of this study was to investigate the prevalence of heat-related symptoms under heat stress. The cross-sectional study was carried out in a tire plant in Nakonpathom province, Thailand. A total of 343 workers (n = 343) were interviewed using a modified questionnaire. The body temperature and wet bulk globe temperature (WBGT) were measured. The mean, Adjust Relative Risk Ratio (Adjust RRR), and 95 % Confidence Interval (CIs) for the association between chosen factors were estimated using multinomial logistic regression. As a result, the most prevalent heat-related symptoms in workers who were exposed to heat in production plants were heavy sweating (70.71%), red rashes (54.55%), and weakness/fatigue (52.02%). The Adjust RRR heat-exposed was three times higher experienced minor symptoms (Adjust RRR = 2.87, 95%CI = 1.43-5.76) and five times higher experienced moderate symptoms (Adjust RRR = 5.00, 95% CI = 2.25-10.82). Females were found six times more likely to experience minor symptoms (Adjust RRR = 6.11, 95%CI = 2.02-18.48) and ten times more likely to experience moderate symptoms (Adjust RRR = 9.57, 95%CI = 2.94-31.19) than the control group. The mean ear temperature did not exceed 38.0°C for safety reasons. Tire workers reported a high burden of heat-related symptoms. On-site care, training programs, and health monitoring strategies are necessary, especially for workers who intake high antihistamines to reduce the risk of heat strain, not only during the summer season but also during the rainy season.

THE EFFECT OF ADDING CALCIUM ALGINATE MICROCAPSULES ON PERMANENT DEFORMATION OF AC–WC NATURAL ASPHALT BUTON STONE IN INDONESIA
Authors: Desvita Melly Dwi , Djakfar Ludfi , Wisnumurti  , Prasetia Muhammad Syarif
Published: April 2022

This paper discusses natural asphalt deposits of Buton stone (asbuton) in Indonesia, which are very abundant, but the characteristics of asbuton are not yet suitable for road applications. Therefore, asbuton as a binder needs to be used with additives to the asphalt mixture that can react independently to overcome the permanent deformation, such as calcium alginate microcapsules. This study aimed to determine the effect of adding calcium alginate microcapsules on the permanent deformation of AC-WC with asbuton. The microcapsules are made with the main ingredients of water, sunflower oil, sodium alginate (C6H7O6Na), and calcium chloride solvent (CaCl2), which are encapsulated and embedded in the asphalt mixture as a material that can restore the structural function by a self-healing method. The research method uses true experimentally. The variation of the study specimens was the addition of calcium alginate microcapsules at 1%, 1.5 %, 2%, and without calcium alginate microcapsules as control. The test to determine permanent deformation used two tests: 1. Wheel Tracking Test with AASHTO Standard: T 324 – 11, 2. CAL Test with Tex – 245 – F 2014 standard. The results showed no significant contribution with adding calcium alginate microcapsules; better than microcapsules, the mixture decreases in the number of passes. The mixture is easy to change shape rutting. However, adding calcium alginate microcapsules can reduce the value of weight loss, causing the adhesion of the asphalt mixture to increase.
ZOOM OR NOT TO ZOOM: STUDENTS’ ATTITUDES TOWARDS USING ZOOM AT PTUK
Authors: Salhab Reham
Published: April 2022

This study aims to investigate the attitudes of undergraduate students at PTUK (Palestine Technical University Khadoorie) towards using the Zoom platform in their learning process in exceptional circumstances of the COVID-19 pandemic regarding some demographic independent variables: gender, technical skills, GPA, and college type. Three hundred twenty-one PTUK students completed the designed five-point Likert scale online questionnaire from different colleges. The general results suggest that PTUK students’ positive attitudes towards using Zoom with viewing Zoom as reliable and easy to use platform, and reporting that Zoom platform facilitated learning by the flexibility feature like playing the recorded lecture and the ability to share ideas with their peers and their teachers. However, higher levels of preference towards traditional face-to-face formats were found due to a lack of fairness in assessments and privacy intrusion. The variability in the results observed in this study warrants further exploration before definitive conclusions on the impact of the Zoom platform on students’ attitudes can be made. The research findings are unique and novel because insufficient studies related to Zoom were done during COVID-19 in Palestine and globally to investigate the perception of college students about Zoom efficiency. Moreover, the results will benefit teachers to rejuvenate and adapt their teaching strategies to fit students’ needs in diverse ways. Further studies using qualitative and mixed approaches could be conducted for confirmation of these findings.

Improving Transfer Learning for Cross Project Defect Prediction
Authors: Omondiagbe Osayande Pascal , Licorish Sherlock , MacDonell Stephen G.
Published: April 2022

—Cross-project defect prediction (CPDP) makes use of cross-project (CP) data to overcome the lack of data necessary to
train well-performing software defect prediction (SDP) classifiers in the early stage of new software projects. Since the CP data (known
as the source) may be different from the new project’s data (known as the target), this makes it difficult for CPDP classifiers to perform
well. In particular, it is a mismatch of data distributions between source and target that creates this difficulty. Transfer learning-based
CPDP classifiers are designed to minimize these distribution differences. The first Transfer learning-based CPDP classifiers treated
these differences equally, thereby degrading prediction performance. To this end, recent research has proposed the Weighted
Balanced Distribution Adaptation (W-BDA) method to leverage the importance of both distribution differences to improve classification
performance. Although W-BDA has been shown to improve model performance in CPDP, research to date has failed to consider model
performance in light of increasing target data or variances in data sampling. We provide the first investigation of when and to what
extent the effect of increasing the target data and using various sampling techniques have when leveraging the importance of both
distribution differences. We extend the initial W-BDA method and call this extension the W-BDA+‘ method. To evaluate the effectiveness
of W-BDA+‘ for improving CPDP performance, we conduct eight experiments on 18 projects from four datasets where data sampling
was performed with different sampling methods. We evaluate our method using four complementary indicators (i.e., Balanced
Accuracy, AUC, F-measure and G-Measure). Our findings reveal an average improvement of 6%, 7.5%, 10% and 12% for these four
indicators when W-BDA+‘ is compared to five other baseline methods (including W-BDA), for all four of the sampling methods used.
Also, as the target to source ratio is increased with different sampling methods, we observe a decrease in performance for the original
W-BDA, with our W-BDA+ approach outperforming the original W-BDA in most cases. Our results highlight the importance of adjusting
for data imbalance and having an awareness of the effect of the increasing availability of target data in CPDP scenarios.

Published: April 2022

Direct restoration is one of the most common methods of rehabilitation of defects in teeth hard tissues. Composite nano-ceramic restorations are an alternative to traditional prosthetic treatment in view of the growing demand for minimally invasive technologies, since crowns or other prosthetic restorations imply a significant loss of tooth structure with macro-mechanical and more invasive preparation of the dental tissues. This article represents a clinical case of direct composite restoration in carious teeth 3.6,3.7 with aesthetic and functional rehabilitation of contact points.

Published: April 2022

Unit Root and Cointegration tests as well as autoregressive distributed lag (ARDL) are used in this study to assess how selected macroeconomic variables and foreign direct investment (FDI) impact foreign trade (FT) of Jordan for the period (2010-2020). The automatic (ARDL) (E-view) method was used to assess the long-run relationship between the variables, represented in GDP, inflation rate (INFR), interest rate (IR), and FDI as independent variables, and international trade as a dependent variable. Study findings showed a positive and significant relationship between selected macroeconomic factors and direct investment in foreign commerce. This suggests that an increase in FDI by 1% results in a (0.13%) increase in foreign commerce provided that all other conditions remain constant. Gross domestic product (GDP) and foreign trade (FT) have a statistically significant positive association. The association between inflation rate (INFR), interest rate (IR), and international trade are negative and statistically significant. According to the data modified R-square (option R2) amounted to (84.2%), means that independent variables account for (84.2%) of the variation in GDP shares derived from international trade.

Published: April 2022

The article studies the edificatory role of pine growing on the technogenic landscapes of the Kuznetsk coal basin and considers the influence of plantations of Scots pine (Pinus sylvestris L.) with different crown density on the main characteristics of embryozems on the overburden dumps of the coal mining industry. The object of the study was soil samples collected in various zones of the phytogenic fields of pine growing on the transport-free dump of the Kedrovsky coal mine. When choosing test plots, the plantations were ranked according to crown density into unclosed (crown density about 30 %), medium-closed (about 60 %) and closed (about 90 %). In each gradation of closeness, the following zones of influence (phytogenic fields) of trees were identified: undercrown, near-crown (intermediate). The selection of sampling points was carried out taking into account the presence of the identification signs: solid pine litter (undercrown zone), developed moss cover (near-crown zone) and developed meadow vegetation (outer zone). External zones are not found in unclosed and medium-closed plantations. In total, according to the degree of crown density and zoning of phytogenic fields, 7 plantation sites of Pinus sylvestris were identified. Soil samples were taken at each of them from a depth of 0–20 cm in the 3rd decade of September. The enzyme activity was studied in recently collected soil in in 3-fold replications. The fractional composition of soils and their agrochemical properties were determined in dried soil on the basis of the Center for Agrochemical Service “Kemerovo”. The analysis of the results showed that pine stands contribute to accelerated disintegration of technogenic residual rocks with the formation of fine-grained fractions, which are of great soil and environmental importance. Litter combined with grassy vegetation in open pine stands favors the accumulation of total nitrogen in embryozems. It was revealed that the content of readily available forms of phosphorus and potassium depends on lithogenic rather than phytocenotic factors. The study of the enzymatic activity of soils showed that the phosphatase activity decreases with an increase in the phosphorus content, and the protease activity increases with an increase in the nitrogen content. Agrochemical indicators of embryozems are favorable for the growth of herbaceous plants due to horizontal differentiation of space under the influence of stands of Scots pine.

At the moment, there is a wide variety of materials for air filtration, however, it is necessary to develop new, more efficient and cost-effective materials. Numerous studies have shown that in order to obtain a highly effective filter material for fine air purification from particles of 0.1–0.5 μm, ultrafine and microfine glass fibers should be introduced into the composition. Glass fibers have a whole complex of unique properties: thermal, chemical and biological resistance, high specific surface area, filtering ability, strength and resistance to aggressive media. At the same time, glass fibers, unlike fibers of plant origin, do not have the ability to fibrillate, swell and bond formation. Therefore, a strong filter material requires a binder that provides the necessary technological strength while maintaining the specified filtering characteristics. The study of composite material based on mineral fiber was carried out, polyadherical complexes of aluminum, thermomechanical pulp (TMP), polyvinyl acetate (PVA) and polyethylene (PE) were used as binders. The main indicators are the tensile strength, capillary absorption, resistance to air flow and permeability coefficient. The novelty of this work lies in the application of TMP and PE as binders in the composite material based on glass fibers. The addition of a binder based on TMP to the composition is advisable in the range of 5–30 % of the fiber mass, for PE this range is 2–10 %. The studied composite material with the addition of PE as a binder has sufficient technological strength, a low coefficient of permeability and resistance to air flow. PE can be used as a promising binder for composite filter materials based on glass fibers for air purification.

A method for homogeneous nitration of kraft lignin (KL), which consists in its treatment with acetyl nitrate in 1,4-dioxane, tetrahydrofuran, or dimethyl sulfoxide, has been proposed. The effects of reaction time and consumption of acetyl nitrate on KL nitration were studied. A new absorption band with a maximum at 430 nm due to aromatic nitro groups appears in the ionization spectra upon KL nitration. The intensity of this absorption band rises with an increase in consumption of acetyl nitrate and reaction time. At the same time, the intensities of two absorption bands of phenolic hydroxyl groups in the range of 230–300 nm decrease. At the highest acetyl nitrate consumption of 71 mmol / g KL, phenolic absorption bands are practically absent in the ionization spectrum of the products, which, apparently, can be explained by KL acetylation. To analyze the ionization spectra, they were deconvolved. The spectra of reaction products can be described by 3–5 Gaussians with an error of no more than 5 %. The proposed method makes it possible to synthesize the KL nitrated with nitrogen content of up to 2.4 %. Depending on the aprotic solvent used, the kinetic curves of nitration are different. A specific feature of KL nitration in tetrahydrofuran is the presence of an induction period, the duration of which decreases with increasing temperature and which practically disappears at temperatures above 30 °C. The introduction of small additions of nitrites into the reaction mixture makes it possible to reduce the induction period. The KL nitration in dimethyl sulfoxide occurs at a low rate that also increases significantly in the presence of sodium nitrite.

Restoration of lands disturbed by anthropogenic impact is currently the most urgent issue in the light of the gradually decreasing area of commercially valuable plantations. Reclamation of quarries includes restoration of artificial landscape by carrying out various kinds of measures. We have surveyed the quarries located in the northern districts of the Arkhangelsk region. These quarries were used for sand mining in the construction of roads of federal and regional importance. No forestry activities were carried out in one of the quarries. It was adopted as a control site and abandoned to natural regrowth. Deciduous trees and shrubs (birch, willow) in some places grow there after a decade and a half. In two other surveyed quarries mechanical soil treatment was carried out and seedlings of Scots pine (Pinus sylvestris L.) were planted. This species is used for planting on sandy soils to form valuable productive stands. Studies have shown that pine young stands of the second age class have quality class II, with the average forest inventory values of a diameter of 14.6 cm, a height of 15.6 m and a stock of 168 m3/ha. The plants are healthy, physiologically developed with the average annual increment of 56 cm over the last decade. Forestry measures effectively carried out in the development of sand quarries, firstly, provide the necessary optimal conditions for growth and development of plants, and, secondly, biologically productive areas of the land surface are formed due to forest reclamation. These territories are an excellent reserve for increasing the areas covered by forest vegetation.

Common hazel is valuable for its nutritional and medicinal properties and its ability to provide soil conservation functions. However, the morphological characteristics of this plant have not been studied sufficiently. The research purpose is to identify features of significant morphological characteristics of crowns of nut-bearing hazel plants, to assess the biological diversity of these characteristics at different heights, under the forest canopy and on the glades for further detection of forestry and ecological functions of this plant, and to select ornamental and other economically valuable forms. The nut-bearing hazel plants growing in the mountain forests of the North-Western Caucasus at the altitude of 450–600 and 1,300–1,500 m above the sea level under the forest canopy and on the glades were the objects of the research. We studied the diameters of the central and three largest trunks, the crown and the base of the bush, its height, the number of shoots up to 4 years old and older, the total number of shoots in the bush, the density and shape of the crown. We examined 200 ramets that had entered the fruiting stage. The diversity index was calculated according to the authors’ method (Sukhorukikh-Biganova). At the altitudes of 1,300–1,500 m above the sea level, under better humidification compared to the sites located at the altitude of 450–600 m, hazel has statistically reliable better development of average diameters of the central and three main trunks and crown, higher total number of shoots up to 4 years old and older. Hazel trees have superior crown and bush base diameters, greater number of shoots up to 4 years old and older, the total number of shoots in the bush on the glades in conditions of good light compared to those under the forest canopy. Here the plants are more likely to form bushes with a spreading and thick crown. The upper sites showed a significantly higher diversity index for the average diameter of the three largest trunks of the hazel bush and the highest number of shoots older than 4 years. There is a significantly superior difference in the morphological diversity index for the average diameter of the bush base, the number of shoots up to 4 years old and older, the total number of shoots, and crown density on the glades compared to the sites under the forest canopy. In terms of crown shape, the diversity index is higher under the forest canopy than on the glade. The generalized indices of diversity of quantitative, qualitative and general morphological characteristics of hazel bushes did not differ significantly at different heights, under forest canopy and on the glades.

Current climate change is affecting forests and requires a specific forest management strategy. The review aims to analyze the impact of observed and projected climate change on the tree species adaptation response with regard to their intraspecific differentiation to determine the potential for further research and develop forest management adjustments in the Russian European North. The article shows that long-term responses in forest ecosystems are related not only to thermal shifts, but also to changes in moisture regime, insolation, distribution of pathogens, etc. Changes in forest ecosystems may involve physiological and genetic mutations in all species and be extended over several generations. Species must undergo evolutionary adaptation due to genetic mutations. With steady warming and changes in air and soil moisture regimes, forest productivity may increase due to a change in the growing season length, increasing photosynthetic activity. On the other hand, productivity is likely to decrease as a result of reduced precipitation and drought. Climatic changes over the vast territory of Russia will occur gradually, and their level will be different in geographically diverse regions. The forest-forming tree species will exhibit various short-term responses associated with the geographical location of the population and the climatic conditions under which the plants evolved during the stable climatic period following their dispersal in the Holocene. At the same time, inherited growth and development parameters will respond to changing climatic conditions, which will be determined by the geographical location of the forest species and their population characteristics. The differential response of tree species needs to be considered when planning forest management measures, adapting them to possible climatic changes.
