Published: December 2023

La reflexión docente constituye una herramienta que ayuda a evaluar y mejorar la práctica educativa, es por eso que, este trabajo tiene como objetivo analizar el discurso matemático utilizado por las personas estudiantes de los cursos de Matemática para Computación I y II durante la aplicación de las videoconferencias, identificando posibles dificultades en la comprensión y comunicación. Fue desarrollado considerando las actividades evaluativas videoconferencia I y II de estos cursos de la carrera Ingeniería Informática de la UNED, durante el III Cuatrimestre del 2021 y el I cuatrimestre del 2022, para ello se analizaron 47 videoconferencias de cada curso. El análisis de los datos se hace sobre el proceso de comunicación de las personas estudiantes presentes en cada videoconferencia y se enfoca en la comprensión del ejercicio o problema planteado, la participación durante la sesión de trabajo y la solución del ejercicio. Los resultados obtenidos en esta investigación mostraron que la discusión entre pares crea una base fuerte para un mejor entendimiento. Además, como es natural pensar, si el estudiantado comunica sus razonamientos usando lenguaje matemático formal, entonces, el mismo comprende a cabalidad los contenidos y conceptos con los cuales está trabajando, sin embargo, hay situaciones en donde la persona estudiante domina los contenidos y conceptos pero no posee las habilidades comunicativas suficientes y necesita apoyo para completar el trabajo, pues de acuerdo con Puga, Rodríguez y Toledo (2016), “el aprendizaje es progresivo y acorde a la edad cronológica del estudiante, porque en sus inicios se usa material concreto y lenguaje natural, para luego utilizar simbología adecuada con formalidad y rigurosidad que la matemática necesita a nivel universitario”(p. 217). Se concluye que, cambiar términos más complejos por expresiones más simples permite a los estudiantes comprender mejor el contenido evaluado, por lo que, se invita al docente a reflexionar sobre su labor y la población meta con la cual se está trabajando. Además, es pertinente cuestionarse si se debe dar énfasis a la comprensión del estudiante para un mejor entendimiento del contenido, o formalizar más el lenguaje matemático a costas de una menor asimilación de los temas por parte del estudiante
GERENCIA DE ALTA VIBRACIÓN COMO TEORÍA EMERGENTE DESDE LA ESENCIA COMUNICATIVA EN INSTITUCIONES UNIVERSITARIAS
Authors: Alvarez Calles Olga Claret 
Published: December 2023

El propósito de éste estudio está dirigido a reflexionar sobre la gerencia de alta vibración desde la esencia comunicativa de los informantes claves en instituciones universitarias, dentro los teóricos que sustentan la investigación se encuentran Reyes y Ruiz (2016) en referencia a la categoría gerencia, Carballo (2014) para la categoría alta vibración y Berlo (2008) a la categoría comunicación, el enfoque ontoepistemológíco se enmarca en el paradigma interpretativo, la corriente Fenomenológica y el método Fenomenológico, de diseño emergente. Los actores sociales o informantes claves, estarán constituidos por aquellas personas que cumplen cargos gerenciales. En cuanto a la realidad evidenciada en la Universidad Nacional Experimental de la Fuerza Armada Bolivariana núcleo Falcón, lugar donde se realizó la investigación, se logró obtener a través de conversaciones con el personal docente, que existen ciertas debilidades, donde se evidencia una comunicación fracturada, puesto que no se presenta una comunicación armoniosa entre las personas que integran la institución, aunado a ello, se observa que hay debilidad en la relaciones interpersonales y por ende presencia de personas tóxicas que fungen como barreras para la comunicación entre el personal.
O ensino da literatura com recurso a música em contexto de português como l2:uma análise da composição musical do cantor Cláudio Ismael
Authors: Alfredo Antoninho , Félix Eusébio 
Published: December 2023

A Literatura é uma das áreas do saber linguístico cujo ensino e aprendizagem, nos últimos anos, parece não estar a ser desenvolvido de forma satisfatória nas escolas públicas moçambicanas. Muitos são os factores que têm contribuindo para que isto aconteça, entre os quais se destaca: a falta do hábito de leitura entre os alunos como resultado da falta de motivação e/ou desinteresse pela mesma, principalmente no ensino médio. Na perspectiva de superar esse drama, vários são os mecanismos didáctico-pedagógicos que podem ser accionados pelos professores, entre os quais a música. O presente trabalho teve por objectivo mostrar a contribuição que a música, enquanto recurso pedagógico, pode dar para a aprendizagem no ensino da literatura nas escolas de Ensino Médio. Privilegiamos, neste estudo, a pesquisa bibliográfica, que consistiu na consulta de alguma literatura abordando o contributo da música no ensino e aprendizagem e, a análise da composição musical (texto) de Cláudio Ismael, cantor moçambicano, explorando, sobretudo, a questão do tema/assunto abordado no texto, o plano formal/estrutural, fónico e morfossintáctico. O estudo demonstrou o quão pode e é válido utilizar a linguagem musical como forma de estreitar os laços entre o aluno e a arte literária na sala de aulas. Foi possível observar, no final do trabalho, o quanto as diferenças da linguagem clássica, diante da modernidade do mundo actual, são diminutas com o auxílio da música.

The oral biofilm contains a wide variety of microorganisms, mostly bacteria, which are responsible for the development of various infections, such as periodontal disease. Periodontal disease is of infectious and inflammatory origin, caused by the present in the biofilm. It acts by destroying the protective and supporting tissues of the dental elements, involving local, systemic, environmental, and genetic factors. Studies show that periodontal disease is directly related to various systemic morbidities, among which we can highlight respiratory problems, where nosocomial pneumonia has stood out, as there is a relationship between it and the microorganisms present in the oral cavity, among which we can highlight Klebsiella pneumoniae. The resistance of this bacteria to antimicrobials has become increasingly frequent, so the search for alternative treatments has been increasing, among them natural products, especially essential oils, as they have numerous therapeutic activities against various microorganisms, among them we will highlight the essential oil of Gaultheria procumbens which has antimicrobial, anti-adherent, anti-inflammatory activities, among others. The aim of this research is to analyze the possible antimicrobial and anti-adherent potential of Gaultheria procumbens essential oil against Klebsiella pneumoniae strains. To carry out this research, the Minimum Inhibitory Concentration (MIC) technique was used, which was determined by the microdilution technique in plates containing 96 sterile holes the Minimum Bactericidal Concentration (MBC) will be read 48 hours after the MIC, using plates with 96 holes. The Minimum Adherence Inhibitory Concentration (MIC) was carried out in glass tubes, using a medium with 5% sucrose. This research showed that the Minimum Inhibitory Concentration (MIC) ranged from 256 μg/mL to 512 μg/mL, and the Minimum Bactericidal Concentration (MBC) ranged from 1024 μg/mL to 256 μg/mL. It showed strong and moderate antibacterial, bactericidal and bacteriostatic effects and no anti-adherent effect. The strains tested showed strong and moderate effects on the MIC, and bactericidal and bacteriostatic effects on the MBC, and no anti-adherent effect on the MIC.

Published: December 2023

Binge drinking poses a growing concern, particularly among higher education students, with a notable impact on Black African students in China. This cross-sectional study employed the Alcohol Use Disorders Identification Test (AUDIT) to survey 370 students aged 18 to 45 in a prominent Chinese educational institution. Results indicated that 18.5% refrained from alcohol, while 61% exhibited low-risk use, 18.5% displayed hazardous use, and 5% showed harmful use. Notably, 38% of low-risk students consumed more than two drinks on occasion, and 35% had more than six drinks in a single instance. Given the evident issue of alcohol misuse, it is imperative to implement educational interventions and legislative measures to control the availability of alcohol.
Prospects Of Development Of Sorghum As Ruminant Feed-In Indonesia
Authors: Korima Inge , Mansyur Mansyur , Setiyatwan Hendi 
Published: December 2023

Sorghum plants can be developed in Indonesia as feed for ruminants. This is due to agro-ecological conditions that can be tolerant of land conditions in Indonesia. Dry land can be used for the growth of sorghum because sorghum is a cereal with low water content. The harvest method can be carried out at the age of 85 days to 90 days, due to the high content of organic matter, dry matter, and crude protein. By-products of sorghum or sorghum waste in the form of leaves and stems can be used as forage for ruminants. Antinutrient substances in sorghum can be processed with silage technology to maintain nutrients, feed reserves for a long time, and increase digestibility in the rumen of ruminants to increase feed efficiency.

The effect of long-term mandibular advancement on the hyoid bone and pharynx as it relates to the treatment of obstructive sleep apnoea
Authors: Robertson Christopher J. 
Published: December 2023

Abstract
A cephalometric analysis was carried out to determine the effects of long-term mandibular advancement on the hard and soft tissues of the upper airway and, in particular, the relationship of the hyoid bone to both the cranium and the cervical spine, following mandibular advancement. One hundred consecutively-treated patients (87 males and 13 females; mean age: 49.26 years; SD: 8.56; range: 33–74 years) diagnosed with obstructive sleep apnoea and/or habitual snoring were reviewed at 6-month intervals over 6 to 30 months of treatment with a mandibular advancement splint. Significant changes to both the oropharynx and velopharynx were observed. At 12 months, the posterior airway space had increased from 10.71 mm to 11.99 mm (mean difference: 1.28 mm). At 6 months, significant changes had occurred in the soft palate length and thickness: a mean reduction in length of 1.46 mm (p < 0.0001) and in thickness of 0.57 mm. No changes were observed in the hypopharynx: the position of the hyoid bone remained unchanged in relation to both the cranium and cervical spine in all linear and angular measurements.
The author concludes that mandibular advancement with oral appliances should be considered as a treatment for life.
Physical properties of human premolar cementum: hardness and elasticity
Authors: Chutimanutskul Wanjira , Ali Darendeliler M. , Swain Michael V. , Shen Gang , Petocz Peter 
Published: December 2023

Abstract

Aims: To determine if the cementum on the maxillary right and left first premolars has identical physical properties.

Methods: Ten normal maxillary first premolar teeth, extracted from five orthodontic patients with a mean age of 14.0 years, were used. The teeth had not been subjected to an orthodontic force. The hardness and elastic modulus of the cementum were measured on the buccal and lingual surfaces of the roots at three locations: cervical third, middle third and apical third.

Results: There were no significant side-to-side differences in cementum hardness (Mean side-to-side difference: 0.0063 GPa; SD: 0.0279; p = 0.525) or elastic modulus (Mean side-to-side difference: −0.027 GPa; SD: 0.111; p = 0.814). The hardness and elastic modulus of the cementum decreased from cervical to apical regions on both root surfaces.

Conclusions: Similar physical properties of the cementum on the maxillary right and left first premolars suggest that intra-arch comparisons can be used to investigate root resorption caused by orthodontic forces.
New growth references for assessment of stature and skeletal maturation in Australians
Authors: Lin Ni-Hung , Ranjitkar Sarbin , Macdonald Ross , Hughes Toby , Taylor Jane A. , Townsend Grant C. 
Published: December 2023

Abstract

Background
We have provided evidence of secular increases in stature and acceleration of skeletal maturation in Australian male children and young adults in recent decades, and relatively less prominent secular increases in stature in females.

Aims
Our aims were to construct new references for stature and skeletal age in Australians.

Methods
We conducted a cross-sectional study of 2,497 South Australians, comprising 1,255 males and 1,242 females aged between 9 and 18 years. Clinical records obtained from 1995 to 2005 comprised stature, chronological and skeletal ages of these individuals. Means and standard deviations for stature and skeletal age were visually smoothed for each sex to construct growth charts depicting the 97th, 90th, 75th, 50th, 25th, 10th and 3rd centiles.

Results
Comparisons of the new stature references with the NHMRC (1975) charts indicated an upward shift of stature centiles across all age groups in both sexes by around 4-5 cm. Generally, skeletally advanced individuals tended to be taller, and skeletally delayed individuals tended to be shorter compared with the total sample in younger age groups, but this was less apparent in older age groups. Males aged 9 years in our study were skeletally advanced, on average, by 0.4 years, whereas males aged 17 years were skeletally delayed, on average, by 0.3 years compared with the Greulich and Pyle (1959) standards. In contrast, skeletal and chronological ages were concordant in females.

Conclusion
Our new references for stature and skeletal age provide up-to-date information for orthodontists, paedodontists and paediatricians requiring growth data for young Australians.
Sella turcica bridges in orthodontic and orthognathic surgery patients. A retrospective cephalometric study
Authors: Abdel-Kader Hussam M. 
Published: December 2023

Abstract

Objective
To investigate the prevalence of sella turcica bridges in patients accepted for conventional orthodontic treatment and orthognathic surgery.

Methods
The pretreatment lateral cephalograms of 635 subjects scheduled for orthodontic treatment and 113 subjects scheduled for orthognathic surgery were used. The number of subjects with complete sella bridges and the type of discrepancy (Angle Class I, II, or III malocclusions, skeletal Class 2, 3 or bimaxillary protrusion) were recorded.

Results
Sella turcica bridges were found in 3.74 per cent of the total sample of 748 subjects. In the orthodontic group 3.21, 2.97 and 7.14 per cent of subjects in the Class I, II and III subgroups respectively had sella bridges. In the orthognathic surgery group 2.86 and 10.71 per cent of the subjects in the Skeletal 2 and 3 subgroups respectively had sella bridges. No subjects in the bimaxillary subgroup had sella bridges. In the orthodontic group 2.20 per cent of the female subjects and 1.10 per cent of the male subjects had sella bridges, while in the orthognathic surgery group 1.77 of the females and 4.42 per cent of the males had sella bridges.

Conclusions
Higher percentages of sella turcica bridges were found in subjects with Angle Class III and skeletal 3 discrepancies compared with subjects with Angle Class I, II, skeletal 2 or bimaxillary protrusion discrepancies.
Cranial base and airway morphology in adult Malays with obstructive sleep apnoea
Authors: Banabilh Saeed M. , Suzina A.H. , Dinsuhaimi Sidek , Singh G.D. 
Published: December 2023

Abstract

Background
Obstructive sleep apnoea (OSA) has been described as a public health problem comparable to smoking in its impacts upon society.

Objective
To compare the differences in cranial base and airway morphology in Malay adults with and without OSA using finite element analysis (FEM).

Method
Lateral skull radiographs of 38 adult Malays aged 18–60 years were divided into two groups of 19 (13 male, 6 female). The first group consisted of 19 patients with OSA, defined as an apnoea-hypopnea index > 5/hr of sleep, diagnosed with overnight polysomnography. The second group consisted of 19 healthy, non-OSA control subjects. For each lateral skull radiograph 27 homologous landmarks, which encompassed the naso-oropharyngeal airway, were digitised using MorphoStudio software. The mean OSA and control 2D airway configurations were computed and subjected to t-tests and FEM.

Results
The mean 2D OSA airway was statistically different from the mean control airway (p < 0.01). Inter-landmark analysis revealed that the cranial base saddle angle was more acute in the OSA group (153.9 degrees ± 3.4) compared to the control group (158.3 degrees ± 2.5; p < 0.01). In addition, using pseudo-coloured FEM a relative 58 per cent decrease in nasopharyngeal airway area was found above and behind the soft palate. As well, a 32 per cent decrease in oropharyngeal airway area was located behind the base of the tongue, with a 23 per cent decrease in hypopharyngeal area near the level of the hyoid bone. In contrast, a 96 per cent increase in area associated with downward displacement of the hyoid bone was detected.

Conclusion
Functional airway impairments associated with OSA can be quantified and localised in Malay patients, and are predominantly associated with the morphology of the posterior regions of the cranial base.
Assessment of palatal bone thickness in adults with cone beam computerised tomography
Authors: Gracco Antonio , Luca Lombardo , Cozzani Mauro , Siciliani Giuseppe 
Published: December 2023

Abstract

Aims
To determine the most suitable region of the palate for the insertion of miniscrews.

Methods
The subjects were 72 adult patients between 20 and 44 years of age. The thickness of the bony palate was determined with digital volumetric tomography. Bone thickness was measured 4, 8, 16 and 24 mm posterior to the incisive foramen and 0, 3, and 6 mm lateral to the midline of the palate.

Results
The thickest bone was found 4 mm behind and 6 mm lateral to the incisive foramen. The bone thinned progressively from anterior to posterior and from medial to lateral. A median ridge of bone was present in the 8, 16 and 24 mm sections. In these sections the thickest bone was close to the suture.

Conclusion
The hard palate offers several suitable sites for the insertion of miniscrews for orthodontic purposes. The areas behind the incisive foramen and to one side of the median palatal suture have adequate bone for miniscrews.
Molar distalisation with skeletal anchorage
Authors: Gracco Antonio , Luca Lombardo , Siciliani Giuseppe 
Published: December 2023

Abstract

Background
Distalisation of the upper molars can be used to treat a dental Class II deep bite malocclusion with a flat facial profile. It is a useful procedure when extraction treatment has been refused and providing distalisation is an appropriate solution to the patient’s problem.

Aims
To describe distalisation of the upper buccal segments using a modified distal jet appliance and miniscrew.

Methods
Two case reports are presented. The first case was treated with a distal screw appliance: a modified distal jet appliance with a palatal miniscrew and without the premolar arms. The Nance button was anchored to the palatal bone by a miniscrew inserted through a posterior locating plate. Locating holes in the plate ensured that the miniscrew was inserted into a site with optimal bone in the posterior part of the palate. The second case was treated with a similar distal screw appliance, but in this case the locating plate was embedded in the acrylic button. The miniscrew was inserted through a prepared hole in the button and plate. The locating hole(s) ensured that a screw could be inserted into an optimal site to one side of the median palatal suture.

Conclusions
The distal screw appliance can be used to distalise upper teeth with minimal or no anchorage loss.
