Modulación del aporte de nutrientes al mar interior de Chiloé a través de la Boca del Guafo.
Authors:   , Mundaca Armijo Valentina
Published: November 2024

El Mar Interior de Chiloé (MIC,∼ 41-47°S) desempeña un rol esencial en los fiordos patagónicos, ya que es el encargado de conectar a las masas de agua y nutrientes provenientes del océano con aquellas que provienen de los fiordos a través de la Boca del Guafo. Este sistema estuarino es uno de los más extensos del mundo y altamente productivo. La circulación oceánica en esta región se caracteriza por su complejidad, la cual se atribuye a las características batimétricas, la morfología costera y diversos procesos oceanográficos y atmosféricos, tanto locales como de meso-escala. Su dinámica está regida por los flujos de agua dulce, la influencia del viento y la mezcla turbulenta, siendo esta última predominantemente inducida por el viento y las mareas. Durante la temporada productiva del verano austral, el MIC intercambia grandes cantidades de calor, sal, oxígeno disuelto y nutrientes con el Océano Pacífico Sur a través de la Boca del Guafo (∼43.8°S), un canal relativamente poco profundo. Estos flujos impulsan la productividad del MIC, la cual es modulada por las mareas, un forzamiento de alta frecuencia generalmente no considerado en los modelos de circulación utilizados para estimar los flujos de intercambio. En este trabajo, evaluamos los flujos de entrada, salida, masa neta y nutrientes a través de la Boca del Guafo utilizando un enfoque de modelación regional de alta resolución (2.7 km). El modelo regional se evalúa utilizando observaciones de corrientes y datos hidrológicos in situ, y se cuantifican los impactos del forzamiento de las mareas en las corrientes y transportes. Nuestras estimaciones se comparan con modelos que presentan mayor resolución y con modelos que no han sido forzados con mareas. Además, se empleó un modelo de derivadores lagrangianos para estudiar el origen de las masas de agua que ingresan al Mar Interior de Chiloé. Este modelo resalta que las masas de agua que transitan desde el océano abierto hacia el MIC a través de la Boca del Guafo principalmente tienen su origen en la región al sur de la Boca.
Factibilidad de la determinación de características del daño en rodamientos a partir de vibraciones.
Authors:   , Muñoz Flores Manuel Ignacio
Published: November 2024

Los rodamientos son componentes primordiales dentro de las máquinas, ya que soportan y permiten el movimiento de elementos rotatorios u oscilantes. Las fallas en estos son una de las razones principales por las cuales varias máquinas rotativas tienden a deteriorarse, convirtiéndolos en objeto frecuente de mantención. Muchos daños en rodamientos son provocados por desgaste o fatiga superficial, y a su vez cuando estos tipos de daños están presentes, se producen fuerzas del tipo impulsiva. Este tipo de fuerza presenta una corta duración, por lo que se pueden ver afectadas por interferencias provenientes de otras vibraciones, tales como el ruido o las vibraciones originadas por fuentes externas, generalmente de elementos de máquinas cercanos, por lo que es esencial preprocesar las señales correctamente para obtener resultados precisos. En esta investigación se tiene por objetivo seleccionar e implementar técnicas para conocer las características de un daño en un rodamiento, particularmente el tamaño de un daño en la pista interior y exterior de un rodamiento, provocada por fatiga, debido a lo común que son estos daños. La metodología de este proyecto implica una revisión exhaustiva de la literatura para identificar técnicas prometedoras que permita estimar el tamaño de estos daños. A partir de estas técnicas, en esta investigación se propone el nuevo método DEW que combina la transformada de Wavelet con el análisis de la envolvente de las señales (Wavelet Denoising – Envolvente – WPD específicamente), para estimar el tamaño del daño puntual. Para validar las técnicas empleadas, se utilizan señales simuladas, además de dos conjuntos de mediciones obtenidas de la bibliografía. Estos conjuntos de datos contienen señales correspondientes a rodamientos operando a diversas velocidades, cargas, tamaños de daño, entre otros. Con los resultados obtenidos, fue posible estimar un intervalo de confianza para el tamaño del daño en las distintas condiciones planteadas. A pesar de algunas inconsistencias observadas, el método mostró resultados más precisos con cargas altas, tamaños de fallas mayores o velocidades bajas. En el caso de señales simuladas, se lograron buenos resultados incluso en escenarios con hasta 10 [dB] de relación señal-ruido. Sin embargo, para la evaluación con el conjunto de datos experimentales, esta estimación resultó insuficiente debido a la cantidad de ruido presente, que atenuó los componentes de interés, especialmente el pico de entrada.
The Longitudinal Impact of the COVID-19 Pandemic in Italy: Literacy Acquisition in Low-SES/High-SES Monolingual Children and Low-SES Bilingual Children
Authors: Artuso Caterina , Zappella Denise , Palladino Paola
Published: November 2024

In the present study, we applied a two-year longitudinal design to examine the reading and spelling acquisition of primary school students during the COVID-19 pandemic crisis among three groups with different linguistic conditions and socioeconomic status (SES): low-SES and high-SES monolinguals, and low-SES bilingual children (minority language). Reading speed and spelling errors were examined at the beginning of second grade in fall 2019 (pre-pandemic phase) and tested again, with standardised tests, two years later in fall 2021 (post-pandemic phase) when children attended fourth grade. The results showed that, on average, all the children increased both their reading speed and spelling skills. With respect to the role of the COVID-19 pandemic on basic literacy, we cannot broadly conclude that it hampered literacy, given that all groups (regardless of their linguistic condition) showed development in reading and spelling. However, it is worth mentioning that, in light of the qualitative comparison to the norm, spelling accuracy is noticeably lower in low-SES bilinguals than in monolinguals, whereas reading speed is comparable to the standardised value and does not differ significantly between monolinguals and bilinguals. The results contribute to the debate on the interaction between SES and language literacy acquisition in minority languages, particularly under unique conditions such as the COVID-19 pandemic.

Authors: Wiedemann Sebastián , Pérez Natalia
Published: November 2024

Los autores del artículo, como docentes, reflexionan sobre la necesidad de proponer experiencias en el aula y pedagogías de futuro a partir de ejercicios de exploración perceptiva centrados en el dibujo y en acciones performáticas colectivas, en alianza con las plantas, a fin de cuestionar el sistema del arte y sus clichés. El propósito es acercar al lector a los procesos de creación como laboratorios de pragmatismo especulativo, donde se creen comunidades de coaprendizaje que restauren vínculos y asuman el arte en su desbordamiento e indisciplina para abrir futuros posibles. Los autores concluyen que está en juego la experimentación especulativa de revaloraciones antropodescentradas del valor.
Ser todo y nada. Gestos especulativos en el performance de LadyZunga
Authors: Tamayo-Duque Anamaría , Londoño Manco Juan Camilo
Published: November 2024

El artículo analiza el caso de la performer LadyZunga, desde la perspectiva del giro especulativo, y se enfoca en dos aspectos: cómo su práctica performática problematiza las categorías de sexo, género, identidad y humanidad de manera única -tratando de esquivar e ir más allá de las exigencias sociales de legibilidad de su época-, y cómo ella experimentó imaginativamente desde su corporalidad, su vida cotidiana y sus formas de subjetivación, creando gestos especulativos que emergieron como modos políticos y estéticos de relación con su(s) contexto(s), los cuales arrojan elementos para pensar formas de investigación artística especulativa, políticamente situada, experiencial/existencial y contextual.

Authors: Titova E. A. , Lysenko T. A. , Koblov A. G.
Published: November 2024

Objective: to study procalcitonin (PCT) for evaluating the effectiveness of diagnosing pneumonia and sepsis complicating new coronavirus infection in patients with diabetes mellitus and those without it.

Materials and Methods. A total of 65 patients with new coronavirus infection complicated by pneumonia and sepsis were examined, including 35 patients with type 2 diabetes (53.8%). Among the diabetic patients, 20 (30.8%) had complications (diabetic microangiopathies and macroangiopathies). The age of the patients ranged from 42 to 89 years. PCT levels were determined using an automatic immunochemical electro-chemiluminescent analyzer Cobas e 411 (Hitachi High-Technologies Corporation 24-14, 2020). The reference interval for PCT is 0–0.046 ng/ml.

Results. PCT levels in patients with new coronavirus infection complicated by pneumonia and sepsis combined with diabetes (1.7 ± 1.47 ng/ml) did not differ from those in patients without diabetes (3.1 ± 2.96 ng/ml). However, PCT levels in patients with new coronavirus infection complicated by pneumonia and sepsis combined with diabetes and diabetic microangiopathies were higher than those in patients without diabetic microangiopathies.

Conclusion. PCT levels did not differ between patients with new coronavirus infection complicated by pneumonia and sepsis in combination with diabetes and those without diabetes. Thus, PCT serves as a universal marker of the severity of bacterial infection, regardless of the presence of diabetes.

Authors: Oliveira Rita Cassia de
Published: November 2024

Este artigo é um recorte de uma pesquisa de mestrado finalizada em 2019, que buscou uma melhor compreensão do projeto de ação promovida pela secretaria de educação de um município do Sul de Minas, cuja finalidade foi a de incentivar as práticas de leitura em sua rede pública de ensino. Questionou-se que ações têm sido realizadas nas redes públicas de ensino que promovam e incentivem à atividade de leitura? Neste recorte realizado, objetivou-se a discussão sobre a relevância da formação docente para o desenvolvimento de práticas escolares que promovam e incentivem experiências leitoras de forma significativa e mais efetiva na formação de leitores. Para tanto, foi feita a análise da entrevista realizada com a equipe idealizadora do projeto institucional e do seu documento descritivo. Como resultado, constatou-se que o projeto institucional enfatizou o trabalho com a literatura e o contato prazeroso com leitura, constituindo-se como inciativa de fomento à leitura que busca o resgaste da atividade leitora por meio da leitura literária, dialogando com as políticas públicas nacionais de fomento à leitura. O projeto considerou os aspectos formativos da literatura, privilegiando esse tipo de leitura. Entretanto, percebemos que a leitura literária muitas vezes é usada para diversos fins didáticos, esquecendo-se os aspectos específicos da própria leitura literária. Isso aponta para a necessidade de se (re)pensar a concepção de leitura, que ajudará no planejamento para mediação de forma significativa nas atividades de leitura e escolhas de atividades mais efetivas para a formação do leitor.

Evaluation the Effect of Tumor-Associated Macrophage-Derived Factors on Pancreatic Cancer Microenvironment Cells
Authors: Karakaş Didem , Dere Egemen , Ulukaya Engin , Ozpolat Bulent
Published: November 2024

Purpose: The unique tumor microenvironment (TME) of pancreatic cancer (PCa) is a critical factor contributing to its aggressive and incurable nature. Pancreatic stellate cells (PSCs) are among the most abundant stromal cells in the TME, closely associated with tumor progression, metastasis, and chemo-/radioresistance. Tumor-associated macrophages (TAMs) are another important cell type in the TME, playing a vital role in promoting tumor growth and metastasis. Limited research exists on the interaction between PSCs and TAMs, highlighting the need for more studies to better understand the interaction between these two cell types.
Methods: THP-1 monocytic cells were differentiated into macrophages, and differentiation efficacy was confirmed by morphological analysis and Western blot. PSCs were co-cultured with monocytes/macrophages, and changes in the migration and invasion abilities of PSCs were assessed by wound healing and transwell invasion assays, respectively. To investigate the effects of macrophage derived factors, MCP-1 and Gas6, on PSC-macrophage interaction, these proteins were applied to PSCs, or their receptors (Axl and CCR2) were suppressed using siRNA technology. The effects of Gas6/Axl and MCP-1/CCR2 signaling on PSC cell viability, colony formation, and migration were then evaluated.
Results: While MCP-1 did not induce changes in colony-forming and migration abilities of PSCs, Gas6 treatment caused an induction. This effect was reduced when the Gas6 receptor Axl was suppressed with siRNA, suggesting Gas6/Axl signaling might play critical role in macrophage-mediated changes in PSCs.
Conclusion: Further research is needed to fully understand the interaction between PSCs and TAMs in pancreatic cancer.

Authors: Uyar İbrahim Enes , Baykal Ülkü
Published: November 2024

Aim: This study was conducted to examine postgraduate theses on organizational cynicism in Turkey, where the sample group consisted of healthcare professionals.
Methods: The database of The Council of Higher Education (Yükseköğretim Kurulu (YÖK)) was analyzed using “Cynicism, Organizational Cynicism, Cynic” separately and together, and 58 postgraduate theses were reached, the sample of which consisted of healthcare professionals. The theses obtained were evaluated using the data collection form and descriptive statistics prepared by the researchers.
Results: Within the scope of the study, 86.2% of the theses examined were master's theses and only 8 doctoral theses were found on this subject. It was determined that the first thesis on this subject was published in 2013, 41.3% of the theses were written in the departments of Business/Business Administration/ General Business Administration, and the number of studies increased over the years. It was determined that quantitative research methods were used in 98.2% of the studies, 41.3% of which were conducted in Istanbul, and qualitative research designs were used in only one study.
Conclusion: When the postgraduate theses examined in the study are evaluated in general, it can be said that the organizational cynicism levels of healthcare professionals are at a moderate level. This study is important in terms of revealing the current situation regarding organizational cynicism in health services and creating data for action plans. In addition, it is thought that examining the organizational cynicism levels of health professions separately (physician, nurse, midwife, health technician, etc.) and taking initiatives specific to each profession will provide great benefits to both employees and those receiving service, and this will positively affect the provision of health services and increase the quality of patient care. In addition, the study makes an important contribution by revealing open areas for scientists who will study cynicism.

A decadal survey of the near-surface seismic velocity response to hydrological variations in Utah, United States
Authors: Feng Kuan-Fu , Denolle Marine , Lin Fan-Chi , van Dam Tonie
Published: November 2024

Ongoing climate change leads to an increase in prolonged drought and severe weather events in the United States, particularly pronounced in semi-arid regions such as the western United States. It could have lasting social and environmental impacts. Continuous monitoring of near-surface hydrological processes and groundwater resources will provide helpful information for effective water resource management. The seismological signature of groundwater fluctuations is clear in the temporal variations in seismic velocities, dv/v. To this end, developing a proxy for groundwater level using dv/v is an opportunity but requires further understanding of the relation between dv/v and subsurface hydrology. In this study, we apply single-station cross-component correlation analysis to 28 broadband seismic stations in Utah between January 2006 and March 2023 and analyze the dv/v in the 2-4 Hz frequency band. To explain dv/v, we linearly superimpose thermoelastic stresses, soil moisture estimated from remote sensing data products, and a long-term deep water table pore pressure. We find that the relative contributions of each depend on the location, but adding a long-term water table decline, which is not systematically observed in soil moisture, better fits our data. We conclude that soil moisture alone does not explain the variations in total water storage when subsurface moisture is decoupled from the deep water table. We also conclude that dv/v can be used as a proxy for water storage.
Thin Cambered Lifting Bodies in Ground Effect Flight
Authors: Suppes Adam Bradford , Suppes Galen
Published: November 2024

Ground effect flight uses the ground to block downward dispersion of lift pressures, increasing both lift and lift-drag-ratios (L/D).  For thin-cambered wing sections, L/D increases as the ratio of the wing sections frontal projected height to ground clearance with the ground increases.  This allows thin cambered panels at higher cambers (e.g. 6%) to operate at high L/D with reasonable clearances of water and ground.  Functionally, a thin cambered mid-section of a wing-in-ground (WIG) aircraft delivers more lift per mass than a wing and can replace laterally-extending wings in WIG platforms with frames that allow the tensile strength of the panel to transfer lift forces to the rest of the aircraft.  A catamaran airship design emerges where, with minimal weight penalties, an inboard thin cambered wing is able to: a) increase lift, b) increase surface area for solar power collection, and c) provide a low-resistance path for crossover propulsor benefits in transition from hovering to aerodynamic lifting-body flight.  This paper evaluates the performance of thin-cambered inboard sections for ground-effect machines.
The developmental trajectories of generalization and discrimination in reinforcement learning reflect multiple underlying cognitive processes

A hallmark of human intelligence is the ability to appropriately generalize past experiences to new scenarios. Organizing concepts into categories allows the brain to generalize learned stimulus-reward contingencies to new stimuli within the same category. However, when category membership does not fully predict associated rewards, the brain needs to balance generalizing values within categories and discriminating value differences among individual items. How do generalization and discrimination in reward learning develop throughout lifespan as semantic knowledge is gradually acquired? Using a probabilistic reward learning task with a hierarchical value structure organized by semantic categories, we found children can generalize values of stimuli based on semantic categories at least as early as three to four years old. Furthermore, age-related performance improvement is explained by a combination of increased decision certainty, decreased initial exploration, change in memory retention, and a reduced categorical learning rate.
A systematic review of interventions to increase positive imagery
Authors: Flynn Joseph
Published: November 2024

Background: In psychotherapeutic practice, the role of mental imagery in promoting positive cognitions is often neglected in lieu of assessing and challenging negative verbal cognitions. Mental imagery has been found to play and important role in generating and maintaining symptoms in mood and anxiety problems and has been referred to as an ‘emotional amplifier.’ This study therefore reviewed psychotherapeutic interventions aimed at increasing positive imagery in individuals experiencing depressive symptoms. Methods: Searches were undertaken of PsycINFO, MEDLINE and EMBASE, as well as reference lists of primary studies and review articles identified. Selection Criteria. i) psychotherapeutic interventions aimed at increasing positive imagery, ii) studies with individuals above 16 years old, and iii) use of at least one clinically relevant measure of mood or anxiety symptoms. Only published studies were included. Study Appraisal and Synthesis. Studies were rated for risk of bias using the Cochrane Risk of Bias tool. Results: Results suggest a small effect of the intervention on depressive symptoms (Cohen’s d = 0.29) and no effect of the intervention on depression at follow-up (median time = 4 weeks; Cohen’s d = 0.20). Conclusions: This review presents encouraging results for the efficacy of imagery-based interventions in the context of major depressive disorder and further highlights key trends for future research.

Survey of The Influence of Self Efficacy and Self Resilience to Biology Education Students to Overcoming Learning Loss
Authors: Surtika Surtika , Firdaus L.N , Syafii Wan
Published: November 2024

Distance learning during the COVID-19 pandemic has encountered various challenges. Some of those include uneven internet connectivity, inadequate facilities, and an unsupportive learning environment. Those challenges gradually decreased students' learning motivation and result in learning loss. Their motivation could be influenced by several factors, including self-efficacy and self-resilience. This research aims to determine the extent to which self-efficacy and self-resilience influence learning loss compared to other factors. To achieve this goal, a quantitative approach and survey methods were applied in this cross- sectional research by using biology education students at Riau University as subjects. Its findings indicate a significant simultaneous influence of self-efficacy and self-resilience on students' learning loss. Facility disparities, unstable internet conditions, short learning time, and low interaction between instructors and students are among the factors causing learning loss in students during the distance learning. The conclusions that can be drawn from this research are learning loss is influenced by various factors, including self-efficacy and resilience. This study highlights that the low levels of self-efficacy and resilience observed in students are a result of the declining motivation for learning during remote education.

Prevalence of respiratory symptoms among female workers in the fish processing industry in Odisha
Authors: Ghosh Tirthankar , Patel Jigisha
Published: November 2024

Introduction: The fish processing industry has shown a major scale of growth in recent years. The aim of the present study was to assess the respiratory and pulmonary problems of the female workers of the fish processing industry.
Methods: A total of 60 female workers out of which 40 were in pre processing unit and 20 were in post processing unit of fish processing work were selected randomly for the study held in a fish processing factory in Patia, Odisha, India. The study involved the assessment of physical parameters, application of a questionnaire based on respiratory and pulmonary issues, spirometry for monitoring lung function and Peak expiratory flow rate (PEFR). The study also included an assessment of the worksite by OSHA – recommended ergonomics checklist.
 Results: The fish processing workers were found to complain about respiratory symptoms. Continuous exposure to the fish processing environment leads to a significant reduction in peak expiratory flow rates and lung volumes respectively. The study indicated that female fish processing workers have respiratory and pulmonary problems which might be due to prolonged exposure to the low ambient temperature, cold air loaded with bioaerosols and allergens, and direct contact with chlorinated cold water in their respective work environment.
Conclusion: The fish processing workers were found to complain about respiratory discomfort in the workplace. Prolonged exposure to cold fish processing environments may lead to acute and chronic respiratory disorders.

Published: November 2024

Introduction: Foot covering was one of the first things made by our primitive ancestors. Shoes have played an important role in human culture throughout history. Shoemakers and their health have attracted less attention than the shoes themselves. Musculo-skeletal problems were explored in this study to find out the prevalence and associated factors among the workers of the shoe making community in Kolkata, West Bengal.
Methods: The study was done where shoemakers of the study area were considered and basic information on socio-economic status, demographic characteristics, pattern of musculo-skeletal morbidities. Community based cross-sectional study design was adopted and data collection was done through observation, interview and clinical examination.
Results: This study found high prevalence (45.6%) of musculo-skeletal ailments among the shoe making workers and among all the ailments considered, most of them were suffering from ‘pain in limb joints’ (34.3%) followed by ‘low back pain’ (32.9%) and ‘neck pain’ (31.5%). Chi-square for linear trend analysis showed increasing odds ratio from 1 to 11.16 when the total duration of work for the shoemakers increased from less than 5 years to more than 21 years which was also statistically significant (χ2 = 21.82; p < 0.01). Similar trend was observed where odd ratio increased from 1 to 2.95 when daily working hours increased from less than 9 hours to more than 12 hours. (χ2 = 2.95; p < 0.09).

Published: November 2024

Introduction: Construction processes generate diverse types of dust. This study aimed to specify the concentration of total dust (TD), respirable dust (RD), and particulate matter less than 2.5 (PM2.5) among exposed workers and to identify the chemical composition contained in dust.
Methods: A cross-sectional study; TD, RD, and PM2.5 were personally collected among the workers during the low-rise building construction processes according to NIOSH 0500, NIOSH 0600, and EPA-IP-10A, respectively. The concentrations of dust were analyzed by gravimetric method. The element and chemical composition were determined using X-ray diffraction and ICP-OES. One-way ANOVA was used to test the different concentrations of dust.
Results: The mean concentrations (GM ± GSD) were 1.43 ± 0.55 mg/m3 of TD, 1.08 ± 0.33 mg/m3 of RD, and 0.84 ± 0.25 mg/m3 of PM2.5. The dust concentrations were not significantly different between sites for TD (p = 0.086), RD (p = 0.124), PM2.5 (p = 0.065), and TD and RD concentrations met the standard regulated by OSHA. The XRD pattern presented peaks of aluminum oxide, calcite, ferric oxide, magnesium oxide, and amorphous silica. Ca was the highest concentration in all dust types, followed by a little of Fe, Al, and Mg, like those found in cement powder. Concrete drilling generated the highest dust concentration, followed by sweep cleaning tasks.
Conclusion: Construction workers are exposed to many chemicals in a dusty working environment. Assessing dust concentrations and their physicochemical properties is an imperative tool for improving safety in construction industries.

Introduction: Chronic venous insufficiency (CVI) is a condition that the function of venous system is impaired due to insufficiency of venous valves. The prolonged periods of standing or sitting is considered the most crucial risk factor of CVI. This study aims to determine the prevalence and associated factors of CVI among seafood processing workers.
Methods: A cross-sectional study was conducted through clinical examination and face-to-face interviews with 1160 seafood processing workers in Hai Phong from March to November in 2023 to assess the prevalence and associated factors to CVI.
Results: The prevalence of CVI was 51.9%; the prevalent symptom was restless legs (54.0%); nocturnal cramps (49.3%); tight feeling in calves (43.2%); pins and needles (36.4%); edema lower legs (28.6%). Of all participants 4.1% were C0, 82.9% were C1, 11.0% were C2 and 2.0% were C3. Some factors associated with CVI: female (OR = 2.51, p=0.002); advanced age; prolonged periods of standing or sitting (OR = 2.08, p=0.001); overweight and obesity (OR =1.82, p=0.037); Abdominal obesity (OR =2.11, p=0.025); diabetes (OR = 1.95, p=0.045); hypertension (OR =2.59, p=0.004); gave birth to 2 and 3 children (OR = 1.78 and 2.35, p=0.002); working time over 8 hours per day (OR =3.87, p<0.001).
Conclusion: CVI is a disease with high incidence in seafood processing workers. On average, 1 of 2 workers have varicose veins. To prevent CVI, it is crucial to recommend workers exercise between shifts or breaks, have regular health check-ups to detect signs and symptoms of CVI.
Association between Sleep Quality, Internet Addiction and its Associated Factors among Bangladeshi University Students: A Cross-sectional Study
Authors: Ahmed MD. Faisal
Published: November 2024

Background: This study explores the association between sleep quality and internet addiction among Bangladeshi university students. With increasing internet usage, particularly during the COVID-19 pandemic, concerns have arisen regarding its impact on sleep quality. This research aims to investigate this relationship and its demographic variations to provide targeted recommendations for improving student well-being.
Method: A cross-sectional study involving 587 university students (299 males, 288 females) from various regions in Bangladesh was conducted. Participants aged 18-26 years were selected through purposive and convenience sampling. Data were collected via the Personal Information Form (PIF), the Bengali version of the Pittsburgh sleep quality index (PSQI), and the Bengali version of the internet addiction test (IAT). Descriptive statistics, Pearson correlation, independent sample t-tests, and one-way ANOVA were used for data analysis with IBM-SPSS software version 29.0.
Results: The study revealed that 92.33% of the participants reported poor sleep quality, with moderate internet addiction being most common (48.22%). A significant positive correlation (r = 0.608, p < 0.01) was observed between internet addiction and poor sleep quality. Gender differences were significant for sleep quality but not for internet addiction. Socioeconomic status and residential division influenced both internet addiction and sleep quality. This research highlights a significant association between internet addiction and poor sleep quality among Bangladeshi university students.
Conclusion: The findings underscore the need for targeted interventions addressing internet use and sleep hygiene. Further, longitudinal studies are recommended to explore causal relationships and develop effective strategies for improving student health and academic performance.
