Background: Medical students are under high pressure to perform academically and also face the impact of the COVID-19 pandemic, putting them at risk of developing burnout. Aims: This study aims to evaluate the prevalence and degree of burnout among medical students in Indonesia during 1 month of the COVID-19 pandemic. Methods: From April to May 2021, we conducted an online survey of Indonesian medical students to assess burnout (using Maslach Burnout Inventory-Student Survey, MBI-SS). Results: A total of 1,947 students from 27 universities participated in the study. About 35.5% had burnout, 41.7% with a moderate to high level of emotional exhaustion, 45% had moderate to high level of depersonalization and 66.7% had a low level of personal accomplishment. Conclusion: A total of 35.5% of medical students in our sample experienced burnout. We suggest further research to explore and identify factors related to these findings and the need for potential interventions at global and national level to enhance the well-being of medical students.

Raising the albedo (solar reflectance) of a building's walls reduces unwanted solar heat gain in the cooling season. This saves electricity and lowers peak power demand by decreasing the need for air conditioning. It can also cool the outside air, which can mitigate the urban heat island effect and also improve air quality by slowing the reactions that produce smog. This project quantified the energy savings, peak demand reduction, urban cooling, and air quality improvements attainable from solar-reflective "cool" walls in California; collaborated with industry to assess the performance of existing cool-wall technologies, and to develop innovative cool-wall solutions; and worked with state and federal government agencies, utilities, and industry to create a cool-wall infrastructure, including application guidelines, a product rating program, incentives, and building code credits. Simulations indicate that cool walls provide annual energy savings, peak demand reduction, annual emission reduction, and summer heat island mitigation benefits comparable to those yielded by cool roofs, and are helpful across California and in most of the southern half of the United States (that is, in U.S. climate zones 1—4). Natural exposure trials conducted at three sites in California and another three sites across the United States indicate that cool-wall materials tend to stay clean and reflective. Significant advances were made in novel cool-wall technologies, such as fluorescent cool pigments that expand the color palette for cool-wall products. We prepared guidelines for the climate- and building-appropriate use of cool walls, convened a stakeholder workshop, and created a working group. Ongoing efforts seek to introduce or expand cool-wall provisions in building energy standards, green building programs, and energy efficiency incentive programs, and to develop a cool-wall product rating system.
