Summary: This study investigated the relationship between sleep quality and bedroom characteristics among residents in urban Bangkok. Results showed that the presence of cockroaches and Aspergillus spp. was positively associated with poor sleep quality, while perceived cold indoor air temperature also contributed to poor sleep quality. Regular cleaning to reduce indoor allergens and maintaining a comfortable indoor air temperature are recommended to improve sleep quality among apartment residents in urban Bangkok.

Summary: The special climatic environment at high-altitude leads to common sleep problems for local inhabitants. Analyzing the relationship between bedroom environment and sleep at high-altitude is crucial to improving sleep quality. This study found that the sleep quality of high-altitude residents in summer is more associated with environmental factors in the bedroom, while in winter, the dry environment and indoor heating affect their sleep quality.

Summary: The purpose of this study is to evaluate the multi-functional use of the domestic sleep environment (bedroom) and present evidence on outcomes that can be identified. A survey was conducted with 304 participants in Australia to investigate the relationship between occupants' use of the bedroom space and their sleep habits. The study found evidence that today's bedrooms are used for more than just sleeping, reflecting the respondents' multi-functional needs.

Summary: A four-week-long field intervention experiment was conducted to investigate the effects of different ventilation rates on sleep quality and cognitive performance in bedrooms. The study found that lower ventilation rates resulted in significantly less deep sleep, more light sleep, and more awakenings. Additionally, a clear difference in deep sleep duration was observed between high and low ventilation rate conditions. However, no differences in cognitive performance were observed between the different ventilation conditions. These findings highlight the importance of proper ventilation control for optimal sleep quality.

Summary: Children with asthma living in urban areas in the U.S. are at higher risk for asthma morbidity and poor sleep outcomes, which may be influenced by environmental factors related to urban poverty. This study investigated the association between environmental factors and sleep outcomes among urban children with and without asthma, and examined the role of napping in this association. The study also explored whether these associations varied by health status or race/ethnicity.

Summary: Higher SES families tend to have more media devices available at home, while lower SES families are more likely to have media devices in children's bedrooms. The presence of media devices in children's bedrooms is associated with increased screen time and shorter sleep duration per day. Mobile devices in the bedroom show a similar or even stronger influence on children's screen time and sleep duration compared to television.

Summary: The study showed that cognitive style, personality, and ideology can predict motivated reasoning and endorsement of human-caused climate change. Those who accept human-caused climate change are less likely to engage in biased reasoning and are more likely to engage in objective reasoning about climate change compared to those who deny human activity as a cause of climate change.

Summary: This article applies a motivational perspective to explore the implications of physicians' longitudinal assessment. It reviews the literature on situated expectancy-value theory, achievement goals, mindsets, anxiety, and stereotype threat in the context of testing and assessment. The review suggests that testing has several motivational benefits, but high-stakes, standardized tests pose potential challenges and costs. Attention to instructional framing, test purposes and values, and longitudinal assessment frameworks can enhance motivational benefits and reduce potential costs of assessment.

Summary: This study investigates the relationship between urban form and canopy layer urban heat island (CUHI) using a relatively large sample of microclimate sensors in Seoul, Korea. The study compares different statistical models and finds that the spatially explicit gradient boosting decision tree (GBDT) model has the highest accuracy. The study also shows that the effect of urban form on CUHI varies at different time instances during the day. These findings provide valuable insights for planners to understand the complexity of urban climate and reduce CUHI magnitude.

Summary: Windcatchers provide effective low-energy ventilation and summer passive cooling in temperate climates. However, their use in winter is limited due to significant ventilation heat loss and potential discomfort. This study evaluates the applicability of windcatchers in low-temperature conditions, highlighting the need for control strategies to reduce over-ventilation and the integration of heat recovery or thermal storage to enhance winter thermal conditions.

Summary: The home environment and sick building syndrome (SBS) symptoms in five southern Chinese cities have been studied over time. The study found a decrease in asthma prevalence and an increase in allergic rhinitis. Cockroaches, rats, mice, mosquitoes or flies were identified as consistent biological risk factors for SBS symptoms, while redecoration, buying new furniture, and traffic air pollution were identified as other risk factors.

Summary: This study experimentally investigated the emission characteristics of droplets around the mouth during dental treatments. The results showed that the peak mass fraction of droplets occurs within the size range of 20 μm to 100 μm, and droplets with a diameter less than 200 μm account for over 80% of the mass fraction. The dominant emission direction of droplets is towards the dummy's head and chest, forming an approximately cone shape.

Summary: This study compared the effects of different respiratory behaviors on the distribution of aerosols in a ward and the risk of infection for healthcare workers using numerical simulation. It was found that talking in the ward significantly increased aerosol concentrations, particularly short periods of talking. Wards designed with side-supply ventilation had lower overall infection risk. Talking alternately between healthcare workers and patients slightly extended the impact time of aerosols.

Summary: Mixed-mode ventilation is a promising solution for achieving energy-efficient and comfortable indoor environments. This study found that occupants can thermally adapt when switching between natural ventilation (NV) and air-conditioning (AC) modes within the same day, with the adaptation process stabilizing between 35 to 45 minutes after the mode switch. These findings are important for optimizing thermal comfort in mixed-mode controls, considering the dynamic nature of thermal adaptation.

Summary: Monitoring the potential formaldehyde emission of wood-based materials through test chamber investigations has significantly contributed to reducing indoor formaldehyde concentrations. However, the different methodologies used in these procedures prevent direct result comparison. Empirical models for converting formaldehyde steady-state concentrations based on temperature, humidity, air change rate, and loading were developed in the 1970s and have been modified to accommodate the development of lower-emitting materials. Formaldehyde emissions from wood-based materials are complex and require nonlinear regression tools for mathematical analysis.

Summary: This study investigated the impact of reduced short-wavelength light on the hormone melatonin metabolite 6-sulfatoxymelatonin (u-sMEL) and examined the association between previous day's light exposure and u-sMEL. It was found that reducing short-wavelength light during the day did not change the concentration of u-sMEL. Personal photopic illuminance was positively correlated with u-sMEL in the reference week. The illuminance had a significant impact on u-sMEL, as shown by the evaluation of the mean of all three urine samples. However, this correlation was not found in the experimental week.
