Authors: Pérez Gaibor Nancy Concepción , Moraima Peña Patricia
Published: August 2023

La tecnología dentro del plano educativo, puede ser entendida como el conjunto de recursos, procesos y herramientas relacionadas con las Tecnología de la Información y la Comunicación (TIC), diseñadas para lograr los alcances que cada institución proyecta, sin descuidar las estrategias emanadas desde el sistema educativo en sus diversos espacios y niveles. El objetivo del trabajo es documentar publicaciones relacionadas con el uso y abuso de las TIC, en el proceso enseñanza-aprendizaje en cualquier nivel educacional. La metodología es de tipo documental, empleando a la hermenéutica como método analítico. Los resultados denotan que las consecuencias adversas producto del uso incorrecto de las TIC se destacan: distracción y dispersión de los alumnos dado las infinidades de opciones existentes que los conduce hacia áreas no productivas como, por ejemplo, los juegos en línea. Acumular excesiva información produce un desbordamiento en cuanto a la cantidad de conocimiento, dejando a un lado el uso correcto de elemento de saturación que cada estudiante de conocer para determinar en qué momento debe parar la búsqueda. Las conclusiones destacan las infinidades de informaciones poco confiables en la red, que cuando no son verificados ocasionan distorsiones en las diversas contextualizaciones que el alumno aborda. Los trabajos que presentan por lo general los estudiantes, son copias de textos encontrados en la Web, perdiéndose el sentido investigativo que enriquezca el conocimiento alimenta la falta de creatividad. Para que la información digital se convierta en conocimiento efectivo, es importante que los educadores se apropien en la reconstrucción del aprendizaje integral.

Post Fire Behavior of Structural Reinforced Concrete Member (Slab) Repairing with Various Materials
Authors: Elsheikh Asser , Alzamili Hadeal H.
Published: August 2023

One of the most significant building materials used to build a variety of infrastructure, military, and civil structures is concrete. It can effectively withstand fire mishaps for a long period of time. This study employs a finite element simulation approach in Three steps: the first involves applying mechanical loading, the second involves applying mechanical and thermal loading; and the third involves strengthening the damaged model. Two different strengthening procedures were used to evaluate the performance of the fire-damaged slab. Two types of strengthening techniques—carbon-fiber-reinforced polymer (CFRP) sheet and slurry-infiltrated fibrous concrete (SIFCON) jacketing—were used. Studying the performance of SIFCON and CFRP together and in two different thicknesses of each for repairing both normal and high-strength concretes after fire exposure is considered limited. An investigation of their behavior can provide insights into how effective the restoration of strength is. The study aims to assess how well various repair materials perform in restoring the durability and strength of reinforced concrete members after being exposed to fire. This will assist in determining the best materials for concrete repair after a fire. Results show that the enhancements by SIFCON with a thickness of 30 mm significantly improved many indices, including load displacement behavior, ductility, and absorption energy of the slab. Doi: 10.28991/CEJ-2023-09-08-013 Full Text: PDF

Published: August 2023

The study was carried out to assess the pollution, impact, and risk level to the surface water environment of pollutants in the water bodies of Soc Trang province, Vietnam. The parameters for evaluating surface water quality and risks included temperature, pH, TSS, DO, BOD, COD, NH4+-N, NO2--N, NO3--N, PO43--P, Cl-, Fet, and coliform. Surface water samples were collected at 35 locations with a frequency of six times (February, April, June, August, October, and December) in 2022. The water quality index (WQI), impact and risk level (risk quotient or RQ, RQ-F), correlation analysis, and principal component analysis (PCA) were utilized in the study. The results show that the surface water has been seriously polluted due to organic matter, nutrients, microorganisms, iron, and salinity. The values of WQI in the dry and rainy seasons fluctuated between bad and very good, indicating that surface water quality is suitable for water transport and other purposes with higher quality requirements. TSS, COD, Fet and coliform have a high impact and risk for the environment in this study area. There were no environmental impacts and risks to NO3--N. Locations with many high-risk pollutants were mainly distributed in residential and coastal areas. The significant negative correlation between the WQI and RQ indicated that the lower the WQI, the higher the environmental risk. The PCA results show that at least six polluting sources affected water quality and caused environmental risks. The results of this study contribute essential and valuable information for improving water quality in the study area through the assessment of environmental impacts and risks. Doi: 10.28991/CEJ-2023-09-08-03 Full Text: PDF

Diabetes mellitus (DM) has become a health problem in various countries, even in Indonesia, multiple of Covid-19 sufferers have DM as comorbid. Treatment of DM can be conducted by delaying glucose intake performed by the α-glucosidase enzyme in the intestine. Treatment using synthetic drugs often causes side effects. Instead to overcome these problems, herbal medicine is a choice. Cymbopogon nardus (L.) Rendle served as a potential candidate as seen from prior  research but related to DM drugs, further exploration needs to be performed. This study aims to acquire a DM medicine by using Cymbopogon nardus (L.) Rendle . The leaves were macerated using 96% concentration of ethanol followed by multilevel fractionation with n-hexane, water and ethyl acetate as solvents. The test results showed that the n-hexane fraction was the best for antioxidant activity and α -glucosidase inhibition with IC50 values of 8,23 ppm and 311,87 ppm while the identification of the compound by using Liquid Chromatograph-Mass Spectrometry (LC-MS/MS) suspected compounds that have a role were ar-turmerone, beesioside N and notohamosin A. Based on the test, the n-hexane fraction was found as a source of antioxidants as well as α -glucosidase inhibitors.

Published: August 2023

This research aims to find learning obstacles for students studying LCM and GCF as a reference in preparing teaching materials that can overcome these obstacles. This research involved 74 grade V students at three public schools in Bandung, Indonesia. The research method used in this study was case study research—data collection techniques using triangulation by providing tests, interviews, and documentation. Data analysis techniques use data collection, reduction, presentation, and conclusions. The results show three categories of learning obstacles: ontogenic, epistemological, and didactic. The ontogenic obstacle was found because the students understood multiples, factors, and arithmetic operations on natural numbers in solving LCM and GCF problems. Epistemological obstacles were discovered because of the limited context in which students understood the concepts of LCM and GCF, so they could not use them in contexts such as word problems. Didactical obstacles were found from learning that was given by the teacher procedurally using factoring methods, namely prime factorization or factor trees. Therefore, these obstacles must be anticipated by designing learning designs that can facilitate learning trajectories, focus on concepts, and make learning more meaningful.

Authors: Rachmawati Andini Dwi , Juandi Dadang , Darhim Darhim
Published: August 2023

Researchers use open-ended as a learning method to help students improve their math skills. Each open investigation of mathematical knowledge produces mixed results for components of mathematical ability, each school level, and the content taught. There are more and more studies on open-ended questions nowadays. This study tested the effectiveness of the open-ended approach assisted by GeoGebra on students' mathematical creative thinking abilities. The use of meta-analysis techniques is to analyze the effect (effect size) of a preliminary study. The instruments used were coding protocol sheets and coding sheets/Comprehensive Meta-Analysis (CMA) programs to analyze data. The resulting findings are that there are differences in the research method with the most significant effect size in the quasi-experimental research method, the research year with the most significant effect size in the 2012-2022 research year, indexing journals with the most significant effect size on web indexing scientific journals; the type of publication that has the most critical influence on the kind of thesis publication. Furthermore, the GeoGebra-assisted open-ended approach to creative thinking ability has no significant effect when viewed from the research characteristics of the sample size and level of education.

Published: August 2023

193 members of the United Nations approved the 17 Sustainable Development Goals in September 2015. According to the 2030 Agenda, the SDGs contemplated the ending of poverty, the protection of the Earth and the promotion of prosperity for all. Sustainable Development Goal 17 (SDG 17) deals specifically with the creation of global alliances for development. The underlying assumption respecting this point is that these stakeholder partnerships encourage the interchange of knowledge, experience, technology, and other resources to administer efficiently the other sixteen SDGs. Although SDG 17 is very well established in theory, in practice there are still appreciable downfalls as to how to successfully make this theory become a reality. This short review will analyse the potential viability of SDG 17 “partnerships for the goals” with respect to SDG 7 (affordable and clean energy), and thereupon SDG 13 (associated with climate action) utilising two south-western France two wind farm initiatives.

Published: August 2023

Kawasaki disease (KD) is an acute febrile illness of early childhood characterized by vasculitis of the medium-sized arteries. There is no diagnostic test for KD because the cause is unknown, so diagnosis relies on the recognition of the diagnostic clinical criteria. The most feared sequela of KD is development of coronary artery abnormalities, which occur in 20-25% of untreated children. IVIG reduces this risk in 2-5% when administrated within 10 days from the onset of fever. Here is reported the case of an infant which resulted resistant to 2 consecutive doses of IVIG. Glucocorticoids are recommended as an appropriate therapy in IVIG resistant Kawasaki disease.
DO NADA AO VAZIO: UM IMPRESCINDÍVEL DIÁLOGO SOBRE O NIILISMO ENTRE HEIDEGGER E A FILOSOFIA ORIENTAL
Authors: Santos Eder Soares , Morais Symon Pereira de
Published: August 2023

Trata-se de apontar neste artigo que em Heidegger há dois caminhos diferentes para se investigar a questão do niilismo, que não são necessariamente excludentes, mas que por se localizarem em pontos diferentes em relação à sua virada (Kehre) de pensamento, acaba sempre gerando o questionamento de se estamos frente ao mesmo projeto ou não. Procuraremos demarcar a discussão e mostrar que seja tomada como uma empreitada de longo prazo ou não, o niilismo enquanto relacionado ao nada, na visão dos filósofos da Escola de Kyoto, em especial Nishitani, não pode ser superado. Por consequência, passamos a investigação da proposta de superação do niilismo e buscamos os antecessores de sua discussão sobre a Vacuidade em Nagarjuna

Authors: Sá José Carlos , Carvalho Afonso , Fonseca Luís , Santos Gilberto , Dinis-Carvalho José
Published: August 2023

Sustainable development is a subject of intense discussion, mainly due to climate change, pollution, and increased waste, among other factors. The governments of various countries worldwide have been setting environmental targets for emissions and consumption to combat climate change and improve the state of our planet. Therefore, it is necessary to have an environmental policy with stakeholder engagement. The literature review method, bibliometric analysis, and visual mappings were applied to understand how these sustainable targets are formulated and used by companies to comply with the limits proposed by governments. The Web of Science platform allowed data collection about Lean and Green, Key Performance Indicators (KPI), and Science-Based Targets (SBT). The carried analyses identified the most relevant papers using the PRISMA method, including their authors, their temporal distribution, and a correlation map using the VOSviewer tool. Hence, mapping the current state of the art concerning the SBT topic. Furthermore, a novel conceptual model is proposed to integrate lean and green and create new KPI applied to the definition of SBT to give companies a path and tools to achieve the climate targets efficiently. Future research should focus on the implementation of the conceptual model in several companies to understand its impact to correct and improve the conceptual model proposed.

Published: August 2023

The priority of resources in the management system of influence on the system of technical operation of machines was evaluated. The proposed systemological model of information support for making managerial decisions regarding the technical operation of machines. The given analogy between the factors of technical influence and the resources required for this is substantiated. These are: “action” - “human resource”; “means” - “material resource”; “environment” - “information resource”. The priority of the information resource in ensuring the efficiency of the technical operation of the machines is determined by expert evaluation methods. The proposed systemological model consists of the structuring and systematization of information resources of dispatch reports and the procedure for performing further analytical procedures performed by information and analytical maintenance of enterprises with the help of software to obtain relevant information. Such continuous monitoring of equipment operation processes provides engineers with the necessary data for: the analysis and selection of an effective model of technical operation of the equipment; to develop alternative management decisions and make the optimal one; development of individual models and maintenance strategies with their adjustment and adaptation to real operating conditions. Also, this model provides professionals with a tool for comprehensive evaluation of the efficiency of the enterprise’s production organization, the dynamics of its development, and the consequences of management decisions in different periods. It makes it possible to make informed decisions regarding the improvement of the management system and the subsequent formation of an effective strategy for the technical operation of machines.
Stimulation of the immune system by liposomes with potassium orotate (review)
Authors: Mosyagin V. V.
Published: August 2023

The review article analyzes the existing world experience in obtaining liposomes for targeted delivery of a medicinal substance potassium orotate to tissue macrophages to stimulate the immune system. The selection of literary sources was carried out on the basis of the relevance of the information and the depth of the research. It has been established that liposomes are nanocontainers, vesicles (vacuoles) formed by a two-layer lipid membrane in the inner space of which the active medicinal substance is enclosed. Liposomes are used in medicine, veterinary medicine and cosmetology for targeted delivery of substances to target cells. They can be obtained by convection method as well as the method of voicing, the method of dissolution and removal of detergent, the method of evaporation with phase reversal, etc. The search and analysis of literature sources and patent database showed that injection method and manual shaking method are widely used methods of liposome production. Another promising means of delivering active components are niosomes – vesicles based on surface-active substance. To obtain niosomes, the method of processing solutions in an ultrasonic disintegrator is used. The well-known immunostimulating agent potassium orotate was chosen as the active substance. The target cells for liposomes are tissue macrophages as the initial link in the immunological chain. In particular, they perform an antigen-presenting function, secrete a number of cytokines, etc. Testing of a drug containing liposomes with encapsulated potassium orotate in experiments on rats and pigs showed its high regenerative ability, antibacterial activity and anti-inflammatory effect. Based on the literature data, a scheme of action of liposomes with encapsulated potassium orotate is proposed.

Published: August 2023

The article presents the results of study of 73 varieties of soft spring wheat from the new samples in the world collection of the Federal Research Center "All-Russian Institute of Plant Breeding named after N. I. Vavilov" in order to include the productive, drought-resistant samples into the working collection on crop breeding in the conditions of the Kirov region. According to the results of the field assessment of 2019...2021, which includes an analysis of the elements of productivity and yield structure, 23 samples were identified as sources of breeding-valuable traits. According to the lowest depression of thevalues of productivity elements in a dry year (2021, НTC = 1.07) relative to the optimal moisture supply (2019, НTC = 1.30), domestic medium-ripened samples RIMA (Moscow region, Ryazan region), Tobolskaya (Altai Kr.), Ulyanovskaya 105 and Ekada 70 (Ulyanovsk region) are classified as drought-resistant, which allows them to be included into breeding work for resistance to summer drought. Resistance to early spring drought was evaluated in the laboratory conditions under simulated drought (sucrose solution, osmotic pressure 6 atm.) and normal humidification conditions (distilled water, 0 atm.) according to the percentage of germination of seeds and the parameters of one seedling (the number of seminal roots, the mass of dry matter). As the result, 19 potentially drought-resistant samples of soft spring wheat were identified. For inclusion into breeding work for resistance to early spring drought, medium-early varieties Zauralochka (Kurgan region, Russia) and Chayka (Belarus), medium-ripened RIMA (Moscow region, Ryazan region, Russia) and Uralosibirskaya (Omsk region, Russia) are recommended.Highly productive samples with complex drought resistance Ekada 109 (Tatarstan, Russia) and Ekaterina (Sverdlovsk region, Russia) have been identified, which provides them to be considered as universal donors for the creation of varieties of soft spring wheat adapted to the conditions of the Kirov region.

Ice cream is a frozen food product containing a minimum of 5% fat and 2.5% milk protein, which is obtained by heat-treating and subsequently freezing an emulsion of fat, milk solids and sugar, with or without other substances. This study aimed to obtain the best ratio of peanut juice and kelubi puree in making ice cream that meet the quality of SNI 01‒3713‒1995. The study was conducted using a completely randomized design (CRD) with four treatments and four replications. Data were analyzed using analysis of variance (ANOVA) and then continued with Duncan’s Multiple Range Test (DMRT) at 5% level. The result showed that the ratio of peanut juice and kelubi puree significantly affected fat, protein, total solids, overrun, viscosity, melting time, and descriptive and hedonic sensory tests. The ratio of peanut juice and kelubi puree (92.5:7.5) was chosen as the best treatment, which had 5.62% fat, 5.83% protein, 144.03 ppm antioxidant activity, 35.44% total solids, 2950.85 cP viscosity, 43.16% overrun, and 13.26 minutes melting time with a description of ivory white color, peanut’s flavor, soft, and a little peanut taste. Panelists liked the hedonic assessment of color, aroma, softness, taste, and overall assessment.

Adolescence is a period of transition or transition from childhood to adulthood. At that time, teenagers are often overwhelmed by a lot of ignorance about their development which can cause their own problems. One of the health problems that are most often experienced by adolescents today is the triple burden of malnutrition, namely undernutrition, excess nutrition (obesity), and iron deficiency anemia. Anthropometric nutritional status measurement is one way of early detection of growth retardation for children. Routinely under the coordination of the Puskesmas, measuring the weight and or height of new school children is one of the screening tools for children's health. Insufficient height is assumed to be the result of long-term malnutrition that can interfere with student learning achievement and low body resistance to disease and child mortality. One of the efforts to minimize this problem is to monitor nutritional status early, especially in the school environment. The School Health Effort (SHE) is the spearhead of the “health promotion school” effort. With the training on nutritional status assessment for the UKS managers/officers of the State Junior High School (SMPN) 13 Semarang City, it can help partners find out an early picture of the nutritional status of students. The method of implementing nutrition screening training activities consists of 4 stages, namely planning, implementation assisted by powerpoint media, and anthropometric measurement tools, evaluation (pre-test and post-test), and reflection. The training participants were students from SHE management, totaling 30 people. Based on the results of the evaluation by comparing the pre-test and post-test results, the participants after being given training understood and were able to practice anthropometric measurements of weight and height, and were able to determine nutritional status by looking at the BMI/U index table.
Marcas de sangre y tinta: sustancias constructoras de parentesco y sentidos de familia en un caso de restitución de identidad
Authors: Massa Jimena María
Published: August 2023

A partir de una etnografía sobre las maneras en que nietos/as restituidos/as (re)construyen sus lazos de parentesco una vez conocida su historia de origen, este artículo describe algunas etapas del singular proceso de restitución de identidad de María Carolina Guallane, una “nieta” que luego de la búsqueda de su ascendencia biológica construyó un modo de nombrar/se, creó sus propias marcas identitarias y configuró un mapa ampliado de afectos familiares. Se trata de la biografía de quien, siendo niña, fue apropiada como parte del plan sistemático de robo de bebés perpetrado por la última dictadura cívico-militar argentina (1976-1983), y que conoció su historia de origen a los 23 años. A esa edad se convirtió en la “nieta 61”; la primera que buscaba a su familia biológica por decisión propia en una época (año 1998) en que ser “hija de desaparecidos/as” todavía provocaba temores y sospechas. El trabajo pretende mostrar las distintas sustancias productoras de parentesco y la pluralidad de conexiones que estas habilitan, y también enfatizar la distinción entre origen e identidad, procurando trascender la oposición entre lo biológico y lo social a la hora de describir el amplio inventario de entendimientos de lo que implica ser pariente.
Dve britanske misije u rudniku Trepča: prilozi za razumevanje politike Velike Britanije prema Jugoslaviji 1944–1945. godine
Authors: Milikić Ratomir
Published: August 2023

The paper explores two British missions in Serbia between December 1944 and June 1945, unknown until now. The purpose of both missions was to protect British interests by surveying the state of the Trepča mining complex in Kosovo and Metohija once the war operations were over. A majority stake in the Trepča lead-zinc mines was held by the British company Trepca Mines Limited owned by a mining magnate, Sir Alfred Chester Beatty. The two missions unveiled not only the importance of Trepča for the war effort of the Allies (as the need for lead ore had increased), but also the manner in which the new communist authorities in the Democratic Federative Yugoslavia treated the foreign capital in the country. The documents used in the paper are kept by the U.K. National Archives (TNA) in London.

Climate change is increasing the risk of extreme weather events, potentially threatening crop yields and global food security. A key benefit of international free trade is risk sharing, because global aggregate production is more stable than that of individual countries which may be adversely affected by extremes. Here we test the hypothesis that diverse sourcing of crops from multiple trading partners reduces exposure to extreme weather, using a detailed trade matrix and range of extreme weather indices. We find that countries with high source diversity have moderate exposure, but that there is wide variation in the degree of exposure in countries reliant on domestic crop production. Global aggregate production and export volatility is stable or declining for most crops, suggesting that source diversification will increase resilience to both climatic and non-climatic supply shocks.
Knowledge Graphs for Seismic Data and Metadata
Authors: Davis William , Hunt Cassandra
Published: August 2023

The increasing scale and diversity of seismic data, and the growing role of big data in seismology, has raised interest in methods to make data exploration more accessible. This paper presents the use of knowledge graphs (KGs) for representing seismic data and metadata to improve data exploration and analysis, focusing on usability, flexibility, and extensibility. Using constraints derived from domain knowledge in seismology, we define a semantic model of seismic station and event information used to construct the KGs. Our approach utilizes the capability of KGs to integrate data across many sources and diverse schema formats. We use schema-diverse, real-world seismic data to construct KGs with millions of nodes, and illustrate potential applications with three big-data examples. Our findings demonstrate the potential of KGs to enhance the efficiency and efficacy of seismological workflows in research and beyond, indicating a promising interdisciplinary future for this technology.

Greater loneliness has often been associated with poorer sleep. However, the temporal dynamics and direction of this association remain unclear. Aim of the current study was to examine bi-directional associations between loneliness and sleep in the daily life of 50 stress-exposed medical students during their first medical internship, a period of heightened stress. We obtained state-level diary- and wearable-based bio-behavioral data collected over the period of seven consecutive days during the internship as well as trait-level questionnaire data completed before and during the internship. Bi-directional associations among greater loneliness and higher daytime dysfunction on trait-level as well as between a higher number of daytime positive social interactions and a shorter diary-based sleep onset latency (SOL) on state-level were identified. In addition, several uni-directional associations between loneliness indicators and sleep were found. Findings of this study point to a vicious cycle, in which sleep and loneliness continuously negatively influence each other.
