Authors: Shi Yi , Shamsul Harumain Yong Adilah , Mohidin Hazrina Haja Bava
Published: November 2023

Gender differences in walking may manifest as disparities in walking behaviour and perception. However, there is a lack of a comprehensive study on walking behaviour between gender and their differences in the environment perception in Chinese heritage cities. Some Chinese heritage cities, like Gulangyu, China are car-free destinations where walking is an essential transportation mode. However, many previous studies suggest that women may be more inclined to fatigue due to intense walking or perceive a greater threat while walking. The inequality of gender in walking has led to the need for gender studies to receive more attention in Chinese heritage cities with car-free destinations. This study explores gender differences in walking behaviour and perception of Chinese heritage cities, intending to create a healthier and more comfortable walking environment for both males and females. Therefore, the data for this study were analyzed using SPSS software, employing ordered regression models and independent sample t-tests. The findings indicate that males are more likely to engage in walking behaviour than females, and they also rate the walking environment higher than females in Gulangyu, China. Moreover, males rated comfort higher than females. These results suggest disparities in walking behaviour and environmental perceptions between male and female walkers in Gulangyu, emphasizing increased attention to healthy walking behaviour and perceptions of females in Chinese heritage cities.

Significant issues related to landslides are exposed tremendously in Peninsular Malaysia which have an impact on human beings, animals as well as properties. Reported over twenty-eight significant landslides taking place between 1993 and 2011 which resulted in more than 100 deaths in total. Most of the landslides are the consequences of accumulation of water in underground soil which is connected to rainfall threshold. To establish an empirical Cumulative-Duration threshold through linear regression, analysis of 69 landslide incidents undertaken as well as rainfall data sourced from Public Works Department (PWD) and Department of Irrigation and Drainage (DID) were collected. A comprehensive assessment of all gathered parameters conducted to achieve the confidential purpose of this research which is to determine the threshold for cumulative rainfall event duration which can be utilized in early warning systems and planning for future safety measures. Thus, correlation between rainfall patterns and landslide events are observed. Cumulative rainfall threshold produced an equation E =  with identical range of event duration 1 < D < 2448 h which acts as a critical line of landslide occurrences. Validation of threshold was revised using recent landslide cases to acquire new threshold values to represent current rainfall induced landslides. The threshold serves as an early warning mechanism and planning to protect lives and property.

The second part of the presented article provides information on the activity of the pituitary, adrenal and sex glands in puberty and during stressful conditions. The relationship between hormones and neurotransmitters that ensure the activity of the body is described in detail, in particular, the effects of follicle-sti­mulating, luteinizing hormones, prolactin, somatotropic and adrenocorticotropic hormones, melatonin, cortisol, adrenaline and norepinephrine, estrogens, testosterone, etc. are given. The data of our own studies on the influence of physical activity of varying intensity (as a stress-modulating factor) on adolescents with different course of the puberty are presented. They confirmed a close relationship between the course of puberty and stress-dependent neuroendocrine factors, showed gender differences in the mechanisms of regulation during puberty. Particular attention in the article is focused on the main pathological conditions and diseases that can be provoked by severe or prolonged stress in adolescence. Features of the course of stress reactions in adolescents are associated with the still incomplete remodeling of regulatory structures. Along with increased vulnerability to stress factors, there is a high adaptive plasticity and vitality. Understanding the mechanisms of interaction between the neuroendocrine effects of stress and the restructuring of the body caused by puberty can contribute to the development of effective medical care measures to preserve the somatic and mental health of adolescents and maintain optimal resilience in adolescence.

Authors: Serra L. , Serpa D. , Silva L.
Published: November 2023

Background and Aim of Study: Caring for individuals afflicted with dementia engenders substantial demands and responsibilities for caregivers, encompassing the extensive time allocation devoted to the care recipient on a daily basis. Furthermore, the psychological attributes inherent in informal caregivers, encompassing traits like social anxiety and social phobia, can exert an influence on the evolution of their personal dynamics over time. This phenomenon potentially yields repercussions for how caregivers offer guidance and assistance to elderly individuals grappling with dementia, particularly in relation to their fundamental daily activities and instrumental tasks. The aim of the study: to analyze the predictive effect of social anxiety and social phobia as psychological characteristics of caregivers, along with the impact of caregiving hours as caregiving-related characteristics, on caregivers’ personality. Material and Methods: This observational and cross-sectional study comprised a sample of 97 participants serving as primary family caregivers completed a sociodemographic questionnaire, the Big Five Inventory, the Anxiety Scale in Social Interaction Situations, and the Social Phobia Scale. Results: The findings revealed that social phobia demonstrated significant predictive power for Openness (β=-0.199; p=0.016) and Extraversion (β=-0.136; p=0.024), whereas the daily caregiving hours negatively affected Conscientiousness (β=-0.145; p=0.011), Agreeableness (β=-0.137; p=0.040), Openness (β=-0.210; p=0.011), and Extraversion (β=-0.175; p=0.003). Conversely, social anxiety did not prove to be a significant variable. Conclusions: The presence of social phobia or higher hours devoted to caregiving for individuals with dementia are factors that impact personality functioning and should be considered in the planning of support programs for family caregivers.

The prevalent adoption of ICT in education has compelled even EGD teachers to integrate ICT in teaching and learning of EGD. However, not every teacher understands the importance of using technology in EGD lessons, even though it offers a lot of benefits for both teachers and learners. Many scholars have attributed this resistance of teachers to many factors, such as gender, age, and attitudes as well as the fact that teachers do not perceive technology as important as they believe that traditional methods are still bearing fruit. In an attempt to understand the actual reasons behind teachers’ resistance to ICT integration in EGD lessons, this study followed a qualitative approach, and semi-structured interviews were used to gather data. Purposive sampling was used to identify 11 EGD teachers to take part in this study. Furthermore, the study employed the Technology Acceptance Model (TAM) framework, which puts emphasis on the acceptance and adoption of technology. This framework assisted in pinpointing factors contributing to ICT resistance and how teachers can accept technology for the purpose of teaching and learning. The findings show that factors such as age, lack of proper skills to use technology, lack of exposure to technology at the tertiary level, attitude, and shortage of resources in schools are contributing to teachers’ resistance to using technology. The study recommends that the department of education should train teachers and provide schools with relevant ICT resources.

Introducción: La bacteria Helicobacter Pylori (Gram- negativo) está asociada a la etiología de gastritis aguda y crónica, úlcera péptica, adenocarcinoma y cáncer gástricos; los métodos de detección que se han utilizado son invasivos, por lo tanto, es importante valorar distintas técnicas no invasivas para su detección en sustratos accesibles como es el suero y la saliva. Además, relacionar la detección de Helicobacter Pylori con la placa dental. Objetivo: Determinar la efectividad de la prueba en saliva y placa bacteriana para la detección de Helicobacter Pylori, mediante la revisión de diferentes artículos científicos. Materiales y métodos: Estudio de tipo descriptivo, transversal y retrospectivo. Constó de la búsqueda 70 artículos científicos en diferentes bases de datos como: PubMed, Scopus, Scielo, Medigraphic, Web of Science, Dialnet y Springer Link. Resultados: Se utilizaron 33 artículos científicos de donde se obtuvo que el uso de la saliva para el diagnóstico rápido de esta bacteria fue recomendado, pero no como un método único de diagnóstico. Con relación a la placa dental está relacionada con la presencia de enfermedad periodontal, por lo tanto, en individuos con un estado de salud bucal sano no es posible detectar la presencia de Helicobacter Pylori mediante pruebas en placa dental. Conclusión: La saliva es considerada un método rápido de diagnóstico y la placa dental está relacionada con la enfermedad periodontal por lo tanto no es un método indicativo de infección de Helicobacter Pylori.

El clareamiento dental es una alternativa que influye en la apariencia física de las personas, sin embargo, puede verse afectado por la adherencia de pigmentos. Objetivo. Determinar la recidiva de color en piezas dentarias clareadas y sometidas a tinción con bebidas cromógenas. Materiales y Métodos. Se utilizaron 90 terceros molares humanos, mantenidos en saliva artificial a 37ºC y 100% de humedad, organizados de la siguiente manera: el grupo experimental se dividió en dos subgrupos, uno para cada peróxido utilizado, y un grupo control, formado por 30 terceros molares cada uno. Posteriormente los especímenes se sumergieron en soluciones pigmentantes (café, gaseosa negra y vino tinto), durante 10 minutos, cada 24 horas por 20 días, y el resto de tiempo dejándolas reposar en saliva artificial. En los tres grupos se realizaron los respectivos registros de color (inicial, post micro abrasión, post clareamiento y luego del proceso de pigmentación) con un colorímetro digital y la guía de colores Chromascop. Los datos obtenidos fueron analizados con la prueba de Kruskal Wallis y un Post Hoc de Tukey con 95% de significancia. Resultados. Se observa una baja dispersión en cuanto a la variación de tonos cuando se utilizó gaseosa negra y café, no así con vino, grupo en el que se observó un notorio pardeamiento. Conclusiones. El colorante más nocivo fue el vino tinto, seguido del café y soda negra, siendo esta última prácticamente inofensiva en la inestabilidad del clareamiento.

Introducción: Entre los principales motivos de consulta odontológica se encuentran las recesiones gingivales, las cuales provocan molestias estéticas y en la mayoría de los casos, producen hipersensibilidad dentinaria, obligando al paciente a cambiar su alimentación y cepillado inadecuado. Es por esto que se han implementado diversas técnicas quirúrgicas para solucionar los problemas que afectan a los pacientes, siendo la técnica de injerto gingival libre la más utilizada, demostrando excelentes resultados, así como otras técnicas como la membrana dérmica acelular. Objetivo: mostrar la utilidad de la membrana dérmica acellular e injerto gingival libre en 2 procesos para el recubrimiento de recesiones gingivales. Caso clínico: se presentan 2 casos clínicos, en los cuales se realiza cirugía plástica periodontal, utilizando diferentes técnicas quirúrgicas en las regiones anterior y posteroinferior, con un seguimiento clínico de 1 año y consecuentemente promoción en salud de los tejidos periodontales, teniendo en cuenta la importancia de realizar un buen diagnóstico y plan de tratamiento, según las necesidades del paciente. Conclusión: la utilidad de la membrana dérmica acellular e injerto gingival en el recubrimiento de recesiones gingivales es una opción para pacientes con características únicas, no solo desde el punto de vista clínico, sino también desde el punto de vista estético y de satisfacción del paciente, aun así, se considera pertinente realizar más investigaciones acerca del tema para verificar estos resultados.

Objetivo: Identificar el sistema de conductos radiculares que presentan los segundos premolares maxilares y mandibulares, utilizando la técnica de diafanización dental. Materiales y métodos: 100 segundos premolares humanos, superiores e inferiores, fueron donados por distintos centros odontológicos de la ciudad de Quito. Los mismos fueron seccionados a nivel amelocementario para disponer de la raíz. Se permeabilizó el conducto radicular con lima K # 10 y se procedió a inyectar tinta china Pelikan ® en la cámara pulpar y conductos radiculares. Para lograr la descalcificación, los dientes se sumergieron en un frasco de vidrio con ácido nítrico al 5%. El proceso de deshidratación consistió en colocar los dientes en alcohol al 80 ,90 y 100%. Finalmente, los dientes deshidratados fueron almacenados en metil salicilato. Resultados: La clasificación tipo I de Vertucci fue predominante en 50 segundos premolares superiores con un total de n=25 (50%) piezas seguida de la clasificación tipo IV n=16 (32%) tipo V n=6 (12%) tipo III n=4 (4%) y clasificación tipo VII n=1 (2%).  Los 50 segundos premolares inferiores restantes presentaron la clasificación tipo I de Vertucci en un 74% correspondiente a n=37, seguida de la clasificación tipo IV n=8 (16%) y tipo III n=5 (10%). Conclusión: La diafanización es una técnica que permite observar de forma directa y tridimensional la anatomía interior de los dientes extraídos. En este estudio la clasificación predominante fue la de tipo I de Vertucci, tanto en premolares superiores como inferiores.
