The number of cases of asthma in school-aged children has increased dramatically over the past 30 years. Nearly one in 13 school-aged children suffers from asthma, the leading cause of school absenteeism accounting for over 10 million missed school days each year. Asthma is a chronic obstructive lung disease caused by inflammation and increased reaction of the airways to various triggers. Sympt...

OBJECTIVE To assess parental beliefs that minor childhood injuries play a beneficial role in the development of young children. METHODS Mothers and fathers of 159 children, ages 15 to 40 months, completed the Injury Attitudes Questionnaire (IAQ), designed to assess parental beliefs that children "learn from" and "toughen up" as a result of experiencing minor injuries. RESULTS A main effect ...

It is well known that people spend 80-90% of their life time indoors. At the same time, pollution levels of indoors can be much higher than outdoor levels. Not surprisingly, the term ‘sick building syndrome’ (SBS) has been used to describe situations where occupants experience acute health and comfort effects that are related to poor air in buildings (Clements-Croome, 2000). It is an increasing...

In urban vertical housing in Jakarta, air conditioning (AC) is mainly used to create comfort units and spare residents from hazardous outdoor pollution. Residents housing, who have come the surrounding multi-ethnic area, live dense conditions. This situation inflicts conflicts of interest that affect indoor quality (IAQ). research develops a human dimension model for promoting using concept sus...

UNLABELLED In 2001-2003, a team of researchers from the United States and China performed an independent, multidisciplinary review of China's National Improved Stove Program carried out since the 1980s. As part of a 3500-household survey, a subsample of 396 rural households were monitored for particulate matter less than 4 microm (PM(4)) in kitchens and living rooms over 24 h, of which 159 were...

IAQ is a crucial factor affecting the health, comfort, and productivity of workers, particularly those working in enclosed spaces like bank offices. This study aimed to evaluate office’s operational area vault by analyzing concentrations CO2, TVOC, PM10, PM2.5, as well temperature, relative humidity, air movement. Two different ventilation systems were compared assess their impact on IAQ. The a...

Abstract Children spend a large part of their waking lives in school buildings. There is substantial evidence that poor indoor air quality (IAQ) and thermal discomfort can have detrimental impacts on the performance, wellbeing health schoolchildren staff. Maintaining good IAQ while avoiding overheating classrooms challenging due to unique occupancy patterns heat properties schools. Building sto...

Warm air supply is widely used to condition indoor environment in winter. It has been proved that stratum ventilation (SV), as a novel distribution, potentials be applied for heating. The outlet location may affect quality (IAQ) due interaction between thermal plumes from heat sources and room airflows. In this study, the effect of on IAQ SV was investigated 9 cases under heating mode. outlets ...

Air pollution is a major risk factor, and it still remains global cause of death for millions people. Indoor air quality (IAQ) plays an important role in human health as people spend most their time confined spaces. Many studies have recently addressed this issue, but no systematic analysis has been conducted, which the aim our study. We present bibliographic articles on IAQ industrial environm...
