Abstract: Air quality has plummeted to alarming levels worldwide, especially in Vietnam where recently have been recorded to have cities with the lowest air quality. About the pollution situation in Vietnam, PM (particulate matter) has always been one of the most hazardous factors along side NOx and CO. This negative trend has increased the number of patients suffering from respiratory-related diseases and the severity of their conditions through inflammation. However, most Vietnamese asthma patients don't have access to high-quality air quality monitors due to their high prices. As a result, this project focuses on providing those with asthma with a low-cost and portable dust sensor. Through monitoring the concentration of PM2.5, PM1.0, and PM10.0, our project aims to mitigate the impact of PM2.5 on Vietnamese asthma patients. The device was tested by comparison with IQAir's air monitoring device as well as We integrated a dust sensor with a timer, a storage compartment for an inhaler, and a microcontroller for serial communication between components, creating a sensor that assists in dust concentration management and the patient's asthma condition. In the final steps, we did surveys to confirm the need for our device on 300 asthma patients and we expect the developed sensor to be a great assistance for about 50% of Vietnamese asthma patients if mass produced. Ultimately, our sensor was built with a much lower cost, and a smaller size while exhibiting a positive correlation with the IQAir Pro air monitor. It shows little deviation and, thus can produce accurate real-time measurements as well as perform the additional timer task specifically for daily medication reminders of asthma patients.

Abstract: Introduction: Pediatric lower extremity burns pose a significant challenge due to their impact on physical function, aesthetics, and quality of life. This study aims to assess the incidence, severity, management approaches, and outcomes of lower limb burns in children within the context of Bangladesh. Methods: This prospective observational study was conducted in the Department of Burn and Plastic Surgery, Dhaka Medical College Hospital, Dhaka, Bangladesh, from January 2021 to October 2022. In this study, a total of 40 pediatric patients with lower extremity burns were analyzed. Result: The most affected age group was 5–8 years (35%), with a higher prevalence in females (62.5%). Scald burns were the most common cause (35%), followed by flame burns (30%). Superficial partial-thickness burns were the most frequent (37.5%). Surgical intervention was required in 47.5% of cases, predominantly for flame and ash burns. Common surgical procedures included wound excision, scar release, and skin grafting. Delayed hospital admission beyond five days occurred in nearly half of the cases. Functional outcomes varied, with full range of motion achieved in 50% of patients and full functionality restored in 25%. Surgical cases had a higher incidence of hypertrophic scarring and limited functionality. Conclusion: Pediatric lower extremity burns require a multifaceted approach, with early intervention crucial in reducing complications. Delayed admissions contribute to worse outcomes, highlighting the need for improved burn awareness and timely medical intervention.

Abstract: Background: Understanding students' learning styles is essential for improving teaching strategies and optimizing academic performance, particularly in nursing and midwifery education. Learning styles influence how students acquire, process, and apply knowledge, which is crucial in healthcare education where both theoretical knowledge and practical skills are required. This study assessed the preferred learning styles among nursing and midwifery students at SDA Nursing and Midwifery training college, Asamang and examined whether demographic factors influence these preferences. Methods: A descriptive cross-sectional survey was conducted among nursing and midwifery students. A structured questionnaire was used to collect demographic data and assess learning preferences based on Kolb’s Learning Style Model, which classifies learners as Divergers, Convergers, Accommodators, or Assimilators. Data were analyzed using descriptive statistics and chi-square tests to determine associations between demographic characteristics and learning styles. The study employed 160 students using simple random sampling technique. Results: The study found that more than one-third (32.5%) of the respondents were Divergers, indicating a preference for learning through observation, reflection, and brainstorming. Convergers (25.0%) preferred practical application of theories and problem-solving. Assimilators (22.5%) excelled in abstract conceptualization and logical reasoning, while Accommodators (20.0%) favoured hands-on learning and experiential methods. Additionally, the study found no significant association between students' age, level of study, or program (nursing/midwifery) and their learning styles (p > 0.05). This suggests that learning preferences are influenced by individual cognitive styles rather than demographic factors. Conclusion: The study highlights the diverse learning styles of nursing and midwifery students, with a significant proportion identified as Divergers and Convergers, indicating a need for both creative and practical learning opportunities. Despite variations in learning preferences, no significant associations were found between demographic characteristics and these styles.
