Previous studies have shown that indoor environmental quality (IEQ) parameters may a considerable effect on office employees’ comfort, health and performance. Therefore, we initiated research program to help occupants identify IEQ they perceive as risk factors for their in an enhance comfort levels environment. Since assumed employees might different expectations related work area these differe...

For this study, empirical data on the thermal comfort parameters (i.e. room space temperature, velocity and relative humidity) was collected for the computation of the PMV and PPD thermal comfort index for the three flat types. The study shows that wind ventilation has a great effect on the interior comfort condition. This is evident from the diurnal variations of PMV values. Majority of the da...

BACKGROUND Fanger's PMV equation is the result of the combined quantitative effects of the air temperature, mean radiant temperature, relative air velocity, humidity, activity level and clothing insulation. METHODS This paper contains a comparison of suit dresses and summer clothes in terms of thermal comfort, Fanger's PMV equation. Studies were processed in the winter for an office, which lo...

We proposed that expressing gratitude would increase positive perception of a relationship partner, thereby increasing comfort in expressing relationship concerns, which is a form of relationship maintenance. Study 1 (n = 159) showed a relationship between naturally occurring expressions of gratitude and comfort in voicing relationship concerns. Study 2 (n = 178) provided longitudinal evidence ...

Human thermoregulation is achieved via autonomic and behavioral responses. Autonomic responses involve 2 synchronous 'components'. One counteracts large thermal perturbations, eliciting robust heat loss or gain (i.e., sweating or shivering). The other fends off smaller insults, relying solely on changes in sensible heat exchange (i.e., skin blood flow). This sensible component occurs within the...

background: noise is one of the annoying agents in the environment and it is harmful agent in workplaces that its occurrence with work load, there are in many workstations. the aim of this study was to determine the combined effects of exposure to noise and work load on heart rate changes. methods: this cross-sectional study performed on 14 male students into climatic chamber in 2011.the mean ±...

the present study compared simple thermal indices and the indices derived from energy budget models in the northwest of iran. for this purpose, the air temperature, solar radiation, relative humidity, cloud, cover and wind speed of 13 meteorological stations in the northwest of iran during the  the period of 1986 to 2007 were selected for comparison. the results which were extracted using biokl...

Background: Creating a socket with proper fit is an important factor to ensure the comfort and control of prosthetic devices. Several techniques are commonly used to cast transtibial stumps but their effect on stump shape deformation is not well understood. This study compares the dimensions, circumferences and volumes of the positive casts and also the socket comfort between two casting method...

Suboptimal restraint use, particularly the incorrect use of restraints, is a significant and widespread problem among child vehicle occupants, and increases the risk of injury. Previous research has identified comfort as a potential factor influencing suboptimal restraint use. Both the real comfort experienced by the child and the parent’s perception of the child’s comfort are reported to influ...
