This study compares drug patterns and prevalence of risk behaviors in a randomized trial using two methods of administration, Audio Computer-Assisted Self-Interview (ACASI) and Interviewer-Administered Questionnaire (IAQ), among drug users seeking treatment in a drug treatment center. We randomized 735 participants: 367 to ACASI and 368 to IAQ. No significant difference in sociodemographic vari...

Volatile organic compounds (VOCs) are ubiquitous in indoor environments. Inhalation of VOCs can cause irritation, difficulty breathing, and nausea, and damage the central nervous system as well as other organs. Formaldehyde is a particularly important VOC as it is even a carcinogen. Removal of VOCs is thus critical to control indoor air quality (IAQ). Photocatalytic oxidation has demonstrated f...

Indoor air quality (IAQ) is crucial for the wellbeing of university students. Yet, IAQ in student residences highly variable and challenging to monitor. This work first monitor residence with a low-cost sensor network.

in many peoples’ minds, air pollution is associated with the contamination of urban air from automobile exhausts and industrial emissions. growing number of scientific evidence has indicated that in industrialized societies, air within buildings can be more seriously polluted than the outdoor air. in the last couple of decades, with the widespread availability of personal computers, mathematica...

Indoor air pollution has recently become a public concern in Taiwan. People recognize that indoor air quality (IAQ) may be more important than outdoor air quality because they spend over 80% of their time indoors. IAQ could affect health and comfort of building occupants. The objectives of this study are (1) to characterize the indoor concentrations of selected air pollutants at two hospitals i...

There are thousands of indoor ice rink arenas in the United States, Canada, and Europe. The combustion byproducts from the fuel powered ice resurfacing equipment impose a potential health risk to both athletes and spectators. A field survey of ten ice rink arenas in Greater Boston and Halifax, Nova Scotia indicates that the fuel type used by the resurfacer as well as the air exchange rate, the ...

Healthy building design is an emerging field of architecture and engineering. Indoor air quality (IAQ) inevitable factor that should be considered in healthy due to its demonstrated links with human health well-being. This paper proposes integrate IAQ prediction into by developing a simulation toolbox, termed i-IAQ, using MATLAB App Designer. Within the users can input information layout wall-o...

Abstract Background Indoor air quality (IAQ) is a concern in kindergartens as children spend much of their time there. Yet, there shortage biological indicators needed for assessing IAQ. Thus, this study evaluated IAQ using transplanted lichen Usnea misaminensis indicator. Methods Lichen samples, collected from Bukit Larut, Perak, Malaysia, were exposed to indoor and outdoor environments an urb...
