Authors: Shemyakin Alexander V. , Fadeev Ivan V. , Uspensky Ivan A. , Yukhin Ivan A. , Chatkin Mikhail N.
Published: June 2023

Introduction. A review of studies on the protection of threaded connections from corrosion shows that they have leaks that contribute to the development of crevice corrosion, which leads to a decrease in the mechanical strength of threaded connections and complicates dismantling. Modern lubricants and chemical thread fixatives do not provide corrosion protection and disassembly of threaded connections over a long service life, so the development of a more effective lubricant composition is an urgent task.
Aim of the Article. Is to develop an effective lubricant composition to protect against corrosion and improve the disassembly of threaded connections.
Materials and Methods. The parts of the M10 threaded pair with a thread pitch of 1.5 mm made of St3 steel, connecting two products, (prototypes) were lubricated with grease Zh-SKa 2/6-2, lithol-24, grease + oligomer D-10TM 5% by weight, composition of litol-24 + oligomer D-10TM 5% by weight, tightened to the moment of tightening force 80 N‧m, immersed in a 3% hydrochloric acid solution at a temperature of 22‒24°С. After 8 hours, the samples were removed from the solution and left in the air for 16 hours, which represented one cycle. According to the lubrication options, the number of parallel experiments was 5. Exposure duration – 24; 48; 96; 240; 480; 720 hours, after the expiration of which 5 samples of each lubricant option were disassembled, the value of the moment of the release force was recorded, the corrosion damage was assessed, and the coefficient of friction was calculated.
Results An effective lubricant composition has been developed for processing parts of threaded connections, which increases their corrosion resistance and improves dismantling.
Discussion and Conclusion. When adding oligomer D-10TM 5% by weight in litol-24, there is a significant increase in the length of time before the appearance of foci of corrosion on the details of threaded connections and an improvement in their dismantling. Implementation of the obtained results allows to increase the reliability of threaded connections.

A System for Filling Store Displays: Pitting a Single Model against a Set of Demand Forecasting Models
Authors: Myna Artur , Myna Jacek
Published: June 2023

The aim of the paper was to develop the concept of retail display space allocation as a system and to assess the quality of very slow-moving products demand forecasting models (that have not yet been used by retail companies in Poland) as its key subsystem. Forecasts were made using the example of a clothing company. The quality of these models was assessed using the Weighted Mean Absolute Percentage Error. The first step was to build the individual models. Later, the authors built separate models for brick-and-mortar and online stores as well as brands, creating a set of six models. The findings show that the classification approach for very slow movers provides as precise results as the regression approach. No single model or set of models (built with a particular machine learning method) could be identified that made the best demand forecasts for brick-and-mortar stores, as statistical tests generally did not confirm the significance of the differences between the median forecasts.
The Root of Ephraim among Amalek in the Song of Deborah
Authors: Daniels Quinn
Published: June 2023

In the Song of Deborah’s list of groups that went to war, the phrase “from Ephraim, their root in/among Amalek” (Judg 5:14a) has not been adequately explained. To better understand this line and the odd relationship it seems to recall, I investigate the crucial lexeme “root” שרש (*šrš) in biblical and extrabiblical sources. The analysis reveals that a “root” metaphorically refers to a man’s current or future “patrilineage,” that is, his line of male ancestors and offspring. In the Song of Deborah, the “root” of Ephraim therefore refers to one or many of its high-ranking patrilineal lines. Abdon ben Hillel in Judg 12:13–15 supports this conception, as he is, on the one hand, crucially buried at a location defined by both Ephraim and Amalek and, on the other, is portrayed as a prolific progenitor of male sons. In applying this definition of “root” to the internal logic of the Song of Deborah, I conclude that the fighting force from Ephraim was a body of high-ranking lineage-based leadership that mustered Amalekites (and Benjaminites) to war in the Jezreel valley. Alongside Ephraim’s leader(s), Amalek too fought for the allied “people of YHWH” (Judg 5:13).
Biblical Prophecy in Its Ancient Near Eastern Context: A New Interpretation of Jeremiah 30–33
Authors: Carver Daniel E.
Published: June 2023

In a new approach, I interpret biblical prophecy in light of its ancient Near Eastern divinatory context and offer a new perspective on the (non)fulfillment of prophecy. I begin with a description of how divine communication was understood according to Mesopotamian and biblical texts, laying a foundation for comparative analysis. I then apply this approach to the prophecies of restoration in Jeremiah 30–33. I argue that the prophecies in these chapters, originally intended to be fulfilled in the postexilic era, were canceled (except 31:35–37, 33:19–26) and that a new decision or decisions were given to take their place. Nevertheless, these canceled prophecies continue to have great divinatory significance that reveals patterns of how the deity intends to bless and dwell among the people. Ultimately, a close reading of the text in the light of its ancient Near Eastern contexts provides a strong corrective to the ways that these chapters are commonly interpreted.

Published: June 2023

Em Para uma interpretação emergentista do problema da medição; uma hipótese de trabalho, o filósofo da física português, João Luis Cordovil realiza com elegante simplicidade e didatismo uma tarefa que está longe de ser das mais fáceis, a saber, a de introduzir o leitor ao estado da arte de um campo de pesquisa de alta expertise, e o de contribuir para a literatura especializada acrescentando algo de novo ao debate, fazendo, portanto, avançar em alguma medida as fronteiras do conhecimento. A questão apresentada e enfrentada por Cordovil, é, como o próprio autor adianta já no resumo do trabalho, o grande, ou talvez o “único problema” da Mecânica Quântica: o problema da medição.
MILITARIZAÇÃO DA EDUCAÇÃO E OPINIÃO PÚBLICA: REFLEXÕES SOCIOLÓGICAS EM ENUNCIADOS DO JORNAL O POPULAR
Authors: Santos Eduardo , Alves Miriam , Reis Lívia
Published: June 2023

Partindo da problematização de enunciados que versam sobre a chancela da população goiana à militarização de escolas públicas da rede estadual, o estudo seleciona e categoriza textos publicados entre 2015 e 2018 no periódico goiano O Popular sobre a temática “escola militar”. A partir de chaves teóricas apresentadas por Bourdieu (2008; 1987), ele descreve e analisa os posicionamentos que ali emergem acerca do processo de militarização das escolas da rede pública estadual de Goiás. Para isso, utiliza-se o conceito de enunciados, em Bakhtin (1997), como elemento que compõe o discurso da opinião pública, cujas características tangem o senso comum sobre a educação e a política de militarização. Em seguida, busca-se compreender como tais posicionamentos são engendrados e articulados enquanto alicerces de uma suposta “opinião pública”. Assim, além do “olhar sociológico” prescrito por Bourdieu, o estudo utiliza chaves teóricas formuladas por Marx e Engels. Para discorrer sobre dinâmicas próprias do ambiente escolar, ele lança mão de Carvalho (2013) e Aquino (2014). Ao longo do texto apresentam-se possibilidades de compreensão das bases socioculturais que dinamizam os posicionamentos que a “opinião pública” manifesta. Ademais, o estudo possibilitou descrever o lugar social em que se operam os discursos que defendem a militarização da educação em Goiás.

Published: June 2023

No presente estudo busca-se analisar o impacto de empresas familiares, que participaram do Índice de Sustentabilidade Empresarial, na adoção dos Objetivos de Desenvolvimento Sustentável (ODS). A amostra, composta por 43 empresas brasileiras listadas no Índice de Sustentabilidade Empresarial, totaliza 126 observações feitas no período de 2019 a 2021. Os dados foram submetidos à análise fatorial exploratória para estimar as diferentes dimensões dos ODS (social, econômica e ambiental) que, por conseguinte, foram analisados por meio da regressão de dados em painel. Os resultados evidenciaram que empresas com gestão familiar diminuem práticas ligadas à dimensão social dos ODS. No entanto, o fato de a organização ser familiar ou possuir controle familiar não influencia nas práticas ligadas aos ODS nas dimensões social, econômica e ambiental. Ademais, os achados demonstraram que empresas com gestão familiar não estão relacionadas à adoção de práticas dos ODS nas dimensões econômica e ambiental. Esses resultados contribuem para as discussões acerca do meio ambiente, sustentabilidade, investimentos que prezam pela responsabilidade socioambiental, atuação de empresas familiares e aderência aos ODS, especialmente ao evidenciar que as diferentes características das empresas familiares no Brasil que compõem o ISE, geralmente não implicam aumento das práticas ligadas aos ODS. Sendo assim, pode também auxiliar nas decisões dos investidores, credores e órgãos reguladores sobre a adoção de práticas socioambientais.

This dissatisfaction has led to an increased desire for treatments that improve dental aesthetics, including tooth bleaching, which is a conservative and viable option for attaining a patient’s desired smile when tooth integrity is acceptable.1
Prevalence and risk factors of missed appointment among paediatric patients after minor oral surgical procedures in a tertiary hospital in Southern Nigeria
Authors: Ogordi PU , Edetanlen EB
Published: June 2023

Missed appointments are common in paediatric dentistry, yet not many studies have explored its prevalence and associated factors. To determine the prevalence of missed appointments and the associated factors. This prospective study design recruited all consecutive paediatric patients that presented for minor oral surgical procedures from 1st July 2020 to 30th June 2021. Data collected was the age of patients, gender, parents’ educational level, distance from the clinic, type of minor oral surgical procedures and missed appointments. Descriptive and inferential statistics were performed. Chi-square test of association was used to determine the association between study participants’ age, sex, parents’ educational level, the distance from the clinic, and the prevalence of missed dental appointments. Binary logistic regression was used to determine the predictors. Data was analysed using the Statistical Package of Social Science (SPSS) version 26 (IBM, Chicago, IL, USA). A p-value of less than 0.05 was considered significant. A total of 182 paediatric dental patients, age ranged from 0.5 to 16 years and with a mean age of 8.55+3.88 participated. Most (60.4%) of the patients were females and 46.2% of them were of school age. Most of the parents had a tertiary level of education and lived within 7 to 12 kilometers from the clinic. The prevalence of missed appointments was 54.9% and the most performed minor oral surgical procedure was primary tooth extraction. The relationship between age group, minor surgical procedures with missed appointments was statistically significant (P<0.05). Binary logistic regression analysis revealed that the type of surgical procedure was the only independent predictor of missed appointments (p<0.05) The prevalence of missed appointments in this study is remarkably high. Although the age of the patients and the type of procedure was associated with the prevalence of missed appointment, it was only the type of surgical procedure that was a significant risk factor for missed appointment.

Authors: Thomas E , Oettlé Anna C. , Becker PJ
Published: June 2023

Supernumerary teeth (SNT) are often associated with malocclusions. Data on SNT in the South African population are not well documented. To determine the prevalence, distribution of characteristics and any associated complications of SNT in a South African sample of dental patients. The study was retrospective, cross-sectional and descriptive. Method: Orthopantomographs of 12,005 dental patients were reviewed for the presence of SNT. The number, morphology, location, eruption status and orientation of SNT were assessed. Associated orthodontic problems were noted. The prevalence rate was 2.48%. No sexual dimorphism in the distribution of SNT was noted. Types of SNT tabulated were: supplementary, conical, tuberculate and odontoma. Maxilla demonstrated a higher predilection for SNT. Variation in the distribution of SNT in the anterior, premolar and molar regions in each jaw and across jaws was statistically significant. Relationship of eruption status to the morphology and orientation of SNT was of significance. Malocclusions noted were displacement and impaction of adjacent teeth. From an orthodontic perspective, presence of SNT may compromise tooth movement and space closure in patients. Additionally, as majority of SNT in this population were in the maxillary molar and mandibular premolar regions, caution is advised when planning the placement of orthodontic implants in these regions.

Published: June 2023

Rectenna optimization is important for increasing the efficiency and power output of devices that convert radio frequency (RF) energy into DC power. This can be accomplished by optimizing the design and components used in the rectenna, as well as changing the operating frequency and input power level. Optimization algorithms in rectenna design aid in determining the required geometry parameters of the antenna and rectifier, as well as to find the optimal values of passive components used in the design. This paper investigates various algorithms and optimizers based on these which are used for rectenna optimization.
A Review on Detection of Medical Plant Images

Published: June 2023

Both human and non-human life on Earth depends heavily on plants. The natural cycle is most significantly influenced by plants. Because of the sophistication of recent plant discoveries and the computerization of plants, plant identification is particularly challenging in biology and agriculture. There are a variety of reasons why automatic plant classification systems must be put into place, including instruction, resource evaluation, and environmental protection. It is thought that the leaves of medicinal plants are what distinguishes them. It is an interesting goal to identify the species of plant automatically using the photo identity of their leaves because taxonomists are undertrained and biodiversity is quickly vanishing in the current environment. Due to the need for mass production, these plants must be identified immediately. The physical and emotional health of people must be taken into consideration when developing drugs. To important processing of medical herbs is to identify and classify. Since there aren't many specialists in this field, it might be difficult to correctly identify and categorize medicinal plants. Therefore, a fully automated approach is optimal for identifying medicinal plants. The numerous means for categorizing medicinal plants that take into interpretation based on the silhouette and roughness of a plant's leaf are briefly précised in this article.

Published: June 2023

An important principle of an internet-based system is information security. Information security is a very important aspect of distributed systems and IoT (Internet of Things) based wireless systems. The attack which is more harmful to the distributed system and IoT-based wireless system is a DDoS (Distributed Denial of Service) attack since in this attack, an attacker can stop the work of all other connected devices or users to the network. For securing distributed applications, various intrusion detection mechanisms are used. But most existing mechanisms are only concentrated on one kind of DDoS attack. This paper focuses on the basic architecture of IoT systems and an overview of single intrusion detection systems. This paper presents a single detection method for different DDoS attacks on distributed systems with an IoT interface. In the future, the system will provide support for detecting and preventing different DDoS attacks in IoT-based systems.

SDN (software-defined networks) is a new technology that stems from numerous network security enhancements. It handles network data in a flexible manner using highly secure frameworks. The secure SDN model's purpose is to ensure data security. The proposed idea to be executed is a robust firewall protection in a mini net employing a POX controller. In order to deal with network-induced dangers, the huge network connectivity influenced environment requires additional protection. The proposed effort focuses on creating a secure SDN simulation architecture that is managed by Open Source POX Controller. Through a POX-controlled traffic management system and a Fingerprint-enabled authentication technique, the system provides multilayer security. The enhanced security is achieved by assessing network traffic as either elephant or mouse flow and selecting the appropriate security level based on data complexity. Mininet is run in a virtual cloud, where protocols and tools are tested and supported by a virtual machine (VM). The novelty is to produce a secure SDN topology was created using a python-based POX controller in the suggested technique. It also provides a low-cost solution as well as rapid development in conjunction with industrial networks.
Emerging Routing Method Using Path Arbitrator in Web Sensor Networks
Authors: Goud B.Harish , Anitha Raju
Published: June 2023

Sophisticated Routing has a big impact on wireless sensor network performance and data delivery. Because nodes join and leave the network on a whim, routing in WSN is not as simple a task as it is throughout sensor networks that are wireless. The fact that the most of WSN devices are resource constrained is another restriction on how routing is implemented in WSN. The WSN uses a variety of routing protocols. However, the primary goal of this research is to determine the best route from the source to the destination using wireless sensor networks and machine learning techniques Which is Particle Swarm Optimization. In this study, an innovative and intelligent machine dubbed the Path Arbitrator or selector, which will store all sensor data and use machine learning methods, is used to develop a new routing mechanism.

Published: June 2023

The Internet of Things (IoT) now uses the Wireless Sensor Network (WSN) as a platform to sense and communicate data. The increase in the number of embedded and interconnected devices on the Internet has resulted in a need for software solutions to manage them proficiently in an elegant and scalable manner. Also, these devices can generate massive amounts of data, resulting in a classic Big Data problem that must be stored and processed. Large volumes of information have to be produced by using IoT applications, thus raising two major issues in big data analytics. To ensure an efficient form of mining of both spatial and temporal data, a sensed sample has to be collected. So for this work, a new strategy to remove redundancy has been proposed. This classifies all forms of collected data to be either relevant or irrelevant in choosing suitable information even before they are forwarded to the base station or the cluster head. A Low-Energy Adaptive Clustering Hierarchy (LEACH) is a cluster-based routing protocol that uses cluster formation. The LEACH chooses one head from the network sensor nodes, such as the Cluster Head (CH), to rotate the role to a new distributed energy load. The CHs were chosen randomly with the possibility of all CHs being concentrated in one locality. The primary idea behind such dynamic clustering was them resulted in more overheads due to changes in the CH and advertisements. Therefore, the LEACH was not suitable for large networks. Here, Particle Swarm Optimization (PSO) and River Formation Dynamics are used to optimize the CH selection (RFD). The results proved that the proposed method to have performed better compared to other methods.
Randomized Ensemble Approach with ID3 Algorithm For the Prediction datasets with Imbalance Problem
Authors: R Sasirekha , B Kanisha
Published: June 2023

Nowadays, it is significant to make accurate prediction model by handling imbalance problem. When the larger dataset has been used in the prediction model, that data should be classified into classes which gives ‘0’ and ‘1’ to indicate negative and positive results. While classifying this target value, the larger number of instances can reside in one class and the remaining lower number of instances can be stored in another class. Because of this unequal distribution of data, the machine can be biased and there is high possibility to give wrong predictions. An inaccurate Dataset leads to misprediction. Hence, the imbalanced prediction dataset has been taken. This paper gives a proper information on Randomized ensemble approach with ID3 classifier for the imbalanced prediction dataset.

Authors: GÜVEN Ersin , UÇKAN Mehmet , UZUN Ramazan
Published: June 2023

The scale removing process with acid, generally called as the pickling process, is accepted by the steel producers satisfactorily. However, most of the producers tend to develop scale removing process without acid due to the environmental regulations. In the related literature, some methods were studied for finding eco-friendly solutions. Although these studies seem to be promising, pickling process is still dominant as a descaling process before cold rolling applications. In this study, efficient surface cleaning method which is called as dry ice blasting method was used under different parameters on the carbon steel surface as it might be used instead of pickling process. Results of the experiments were studied by observing cross-sectional micro structure of samples. In addition, before destroying samples for hot mounting application, the surface topographies were measured by non-contact device. Finally, surface roughness values of the samples were showed on figures.

Published: June 2023

Environmental concerns prompt the world for a transition to renewable energy sources from fossil energy. Reducing the dependency on non-renewable sources of energy is prerequisite for the sustainable world and less environmental pollution. Biogas energy, which is one of the most important renewable energy sources, is produced by burning organic wastes and can be used in many different fields. In this study, a two-stage approach is undertaken to optimize a biogas supply chain design by incorporating of 30 districts in Izmir. In the first stage, the selection of the most suitable biogas plants is considered by the goal programming approach, which is of great importance to decide the optimal location with high energy potential. The most suitable sites for the biogas plants are obtained as Konak and Narlıdere districts. In the second stage, the location problem of the biogas vehicle charging stations (BVS) for biogas vehicles is handled considering the results of the first stage using mixed integer linear programming (MILP) approach. Computational results demonstrate that it would be more appropriate to establish BVS in 12 districts of İzmir. The model and solution approach are pioneering for supply chain problems and an efficient tool for renewable energy plans.

Gölcük Caldera is in the Isparta Angle, which is an interesting tectonic structure in Southwest Anatolia. This caldera is formed as a result of back-arc volcanism associated with the northward subduction zone of the African plate under the Eurasian Plate during the Tertiary. It attracts the attention of many researchers with its tectonic and volcanic structure. In this article, the results of in situ natural gamma radiation measurements made in the caldera are evaluated. In the study, radioactive element (Potassium (%K), Uranium (eU), and Thorium (eTh)) contents of volcanics were measured in situ with the portable gamma-ray spectrometer, which is effectively used in Geophysical Engineering. The changes in natural gamma radiation of alkaline volcanic are presented with maps. When these maps are examined, it is understood that K%, U-ppm and Th-ppm concentrations of Gölcük volcanic are higher than the world average values. The high potassium concentration draws even more attention. The high potassium content indicates that the local volcanic are ultrapotassic and contain lithospheric materials. In addition, since the radioactive element concentration will reflect the magmatic development, the volcanic stages in the region have been tried to be determined. The number of these stages was determined from the curves of the radioactive data from a purely geophysical engineering (numerical) point of view, and the study area was interpreted as consisting of three different phases. This finding is supported by the results of the articles on the aging studies of the samples taken as a result of observations. In addition to these, the ranges of radioactive elements belonging to these stages were determined.

The concept of topology is widely used in mathematical modeling of spatial objects and in GIS. One such application of fuzzy topological operators, detecting areas affected by Mikania micrantha, was studied by Shi and Liu. The precision of the results was evaluated by applying the intuitionistic fuzzy pre-interior and pre-clouser operators defined by the author to the data included in this study.

With this application example, it has been shown that the newly defined operators give results closer to the real bounds.
Assessing Seismic Crack Performance of Diyarbakır Çüngüş Masonry Stone Bridge Considering 2023 Kahramanmaraş, Hatay, Malatya, Gaziantep Earthquakes
Authors: ÇAVUŞLU Murat
Published: June 2023

Examination of the creep behavior of historical buildings and interpretation of seismic failures in historical buildings are of great importance for the safety and future of these important structures. In this study, time-dependent settlement and three-dimensional (3D) seismic analyzes of a historical stone bridge are investigated using the 3D discrete element modeling technique. For the settlement and seismic analyses, the historical single-span Çüngüş bridge which was built in the 18th century in Diyarbakır-Turkey by Ottoman Empire is used. Since Diyarbakır is in a dangerous zone according to the Turkey seismic map, the examination of this structure is very critical for the history of Turkey. The 3D model of the bridge is created using the FLAC3D program based on the finite difference method and all the stone elements in the historical bridge are modeled separately as blocks. Special interaction elements are defined between the discretely modeled stones. For settlement creep analyses, the Burger-creep material model, which was not used for the creep behavior of historical buildings in the past, is utilized. Firstly, the 500-year long-term creep behavior of the bridge is examined by considering the fix boundary condition and full reservoir condition. According to the creep analyses, it is seen that the most deformation and failure section of the bridge is the arch section. Then, for the seismic analyses of the bridge, free-field and quiet non-reflecting boundary conditions are defined in the model. Furthermore, hysteresis damping coefficients are taken into account in seismic analyzes with the help of special fish functions. 10 various earthquakes are considered for seismic analyses. According to the earthquake analyses, the earthquake behavior of the Çüngüş historical bridge is assessed by considering the full reservoir condition and it is understood that 2023 Kahramanmaraş, Hatay, Malatya, Gaziantep earthquakes significantly changed the seismic safety behavior of Çüngüş single-span historical bridge.
José de Cañizares (1676-1750): vida y obra de un libretista entre el Barroco y la Ilustración, Oviedo, IFESXVIII / Ediciones Trea (ACESXVIII, 12), 2023.

Published: June 2023

José de Cañizares (1676-1750) fue considerado desde el siglo XIX el último representante de un teatro barroco en decadencia. En los últimos cincuenta años se han ido superando esos prejuicios, sin embargo, su trayectoria como libretista y autor de letras para cantar  ha quedado en un segundo plano respecto a su faceta de comediógrafo. Por tal motivo, este trabajo tiene como propósito mostrar evidencias sobre su importancia como libretista para la música en el ámbito hispánico de la primera mitad del siglo XVIII. Además, esta investigación aporta nuevos datos sobre su vida.

El Proyecto Educativo Strava busca fomentar la actividad física y el desarrollo de habilidades sociales en estudiantes a través de la monitorización de tareas y retos vinculados a la asignatura de Educación Física. Este estudio investiga la incidencia del proyecto en la motivación del alumnado y los aspectos que contribuyen a su participación en actividades físico-deportivas. Se utilizó un diseño mixto que combinó una fase cuantitativa, utilizando las escalas de Satisfacción de  Necesidades Psicológicas en EF (SPE-NE) y del Locus Percibido de Causalidad (PLOC), así como preguntas sobre la intención de práctica y una cualitativa, a través de entrevistas semiestructuradas. Participaron 126 estudiantes (67 chicos y 59 chicas) de 1º ESO y 1º Bachillerato. Los resultados demostraron que la motivación de los estudiantes variaba desde la motivación extrínseca a una motivación cada vez más autodeterminada, y que la relación social se convertía en la necesidad psicológica básica más influyente, especialmente en el alumnado mayor, relacionándose positivamente con la intención de ser físicamente activo. Se concluye que el Proyecto Educativo Strava es una propuesta didáctica útil para la promoción de la actividad física en jóvenes ya que ha conseguido implicarlos en la iniciativa, contribuyendo a que sean personas físicamente más activas.
Análisis de los efectos de las estrategias de apropiación de los criterios
Authors: Cano García Elena
Published: June 2023

Los procesos de evaluación participados por el estudiante pueden contribuir a la autorregulación a través del desarrollo del feedback entendido como acción sostenible. Este a su vez viene condicionado por el juicio evaluativo, el cual se fomenta a través de estrategias de apropiación de los criterios, de aplicación de los mismos a la propia tarea o a la de los iguales y de reflexión sobre dicha aplicación. Se realiza una revisión de literatura acerca de la apropiación de los criterios a partir del análisis de 14 artículos. Los resultados muestran los beneficios de desarrollar estrategias de apropiación de los criterios en términos de aumento de la calidad de las tareas. Destaca el uso de ejemplares y de rúbricas, así como de prácticas de evaluación entre iguales. Sin embargo, este proceso no se produce sin un andamiaje. El papel del profesorado es imprescindible tanto para proponer el diseño explícito de estrategias que lleven a la fijación y comprensión de los criterios como para mediar en el proceso que realiza el estudiantado durante la aplicación de los mismos, lo cual permite establecer ciertas implicaciones sobre los procesos de formación para fortalecer la alfabetización evaluativa tanto de estudiantado como de profesorado.
Hablar por hablar. Conversaciones alrededor del diálogo universitario en clase
Authors: Amar Víctor
Published: June 2023

El hecho de hablar en el aula puede adquirir la categoría de diálogo. Estamos ante un modelo de conversación participativa con la intención de exponer ideas, pero siempre de manera alternativa. No obstante, en la actualidad se puede introducir la posibilidad de llevarlas a cabo, también fuera del seno del aula, a través de las tecnologías y aunándoles el factor relacional. Con el objetivo de conocer y comprender la manera de pensar de un profesor universitario sobre el valor del diálogo en sus clases, hemos optado por la metodología de corte cualitativa, donde utilizamos la técnica de la entrevista semiestructurada y el instrumento será el guion. La entrevista fue validada por tres especialistas y se administró a un profesor universitario. Mientras que los resultados se estructuran en base a nueve núcleos temáticos y de significados, que se establecen a partir de comentarios literales del informante junto con un análisis de estos los mismos. Por último, las conclusiones se redactan en relación con las diferentes cuestiones de investigación.

La intervención socioeducativa en la familia a través de programas basados en la evidencia (PBE), permite crear espacios de colaboración entre las familias, los centros educativos y la comunidad. Este estudio se orienta a conocer el impacto de estos programas en los entornos escolares y comunitarios, tanto sobre las familias y su participación en la escuela y la comunidad, como sobre los profesionales y en el vínculo de estos con las familias. Aplicando una metodología cualitativa, se han llevado a cabo 6 grupos focales en los que han participado 23 profesionales del ámbito escolar y comunitario que han participado como formadores de un PBE en dos versiones, una de prevención universal y una selectiva. Los resultados muestran que la participación en el programa mejora las competencias comunicativas de las familias, refuerza su confianza y su autoconcepto. Se favorece la creación de vínculos entre las familias y de estas con las escuelas y los servicios comunitarios. En familias vulnerables el nivel de efectividad resulta limitado, aunque con mejoras en la comunicación familiar o la toma de conciencia de la responsabilidad compartida. El estudio permite identificar limitaciones en la coordinación entre los ámbitos escolar y comunitario.

Published: June 2023

This article discusses the rare clinical situation where cervical cancer mimics the symptoms of a cervical myoma. Cervical cancer is a prevalent cancer in women, often caused by HPV infection, and can cause symptoms such as abnormal vaginal bleeding and pain during sexual intercourse. However, cervical myoma can also cause similar symptoms, making it difficult to differentiate between the two conditions. Delayed diagnosis and treatment of cervical cancer can lead to a poorer outcome for patients, highlighting the importance of accurately identifying the disease. Healthcare professionals should be aware of this rare clinical situation and conduct thorough examinations to differentiate between cervical cancer and cervical myoma. Early diagnosis and appropriate treatment can improve the prognosis for patients with this disease. Women should also be aware of the potential symptoms of cervical cancer and consult a healthcare professional if they experience abnormal vaginal bleeding or pain during sexual intercourse. Vaccination against HPV can help prevent cervical cancer, making it important for women to discuss this option with their healthcare provider. This article reports a case of cervical cancer mimicking a cervical myoma, highlighting the importance of considering this rare clinical situation in differential diagnoses.
