considering the risk of driving and the resulting injuries, it is possible to point out the relationship between human characteristics and driving behaviors; Therefore, the goal of this research was to predict high-risk behaviors in traffic violations based on demographic characteristics and impulsivity of the offending drivers.

study was a cross-sectional study and a descriptive. The statistical population consisted of all accident-causing drivers aged 20 to 65 living in Tehran, of which 353 were selected and included in the study by purposeful sampling. For this purpose, the data were analyzed by using SPS-26 software after collecting the impulsivity questionnaire of Barratt (1994) and the risky driving behavior of Manchester (Risen et al., 1990(.

According to the results variables had a significant effect on high-risk behaviors. Among the background variables, the effect of marital status, education, driving experience and age on high-risk behaviors was confirmed (p<0.05).The direction of the effect of age and education on high-risk behaviors was negative, but the effect of driving experience was positive. Also, single people had more risky behaviors than married. Finally the effect of all three components of impulsivity on high-risk behaviors was confirmed (p<0.05).

Considering the results, it is possible to prevent a part of road accidents by improving the health of drivers. Considering the importance and sensitivity of driving in the event of road accidents, it seems necessary to carry out more comprehensive evaluations among drivers before receiving a license and after that periodically.

One of the concerns about the operation of underfloor air distribution systems is the occurrence of local thermal discomfort such as draught and vertical air temperature difference. In the present study, to investigate these discomfort parameters in a room with the mentioned system, the temperature, mean velocity and turbulence intensity for vertical and horizontal supply air diffuser with 16 and 20°C inlet temperatures were evaluated. These parameters were measured at 0, 30 and 60cm distances from the center of diffuser of the underfloor air distribution system at 8 different heights from the floor. Also, by using the Fanger model, thermal sensation, percentage of thermal discomfort and the percentage of thermal discomfort caused by the draught were determined. The results indicated that the amount of thermal discomfort in a room with an underfloor air distribution system is significantly dependent on supply air direction (horizontal/vertical) and, distance from the inlet diffusers. Also, the results showed that by using proper diffusers, while subjects’ thermal comfort maintains constant, the supply air temperature can be increased from 16 to 20 °C, which is a major step towards reducing energy consumption.

This study examines the impact of phonological awareness training on reading skills in male students suspected for having dyslexia.

In this quasiexperimental research, first the students suspected for having dyslexia in the second grade of elementary school in Mashhad were chosen, and assigned randomly into two experimental and control groups (each group consisted 20 students). In this study, Phonological Awareness Test (Dastjerdi & Soleymani), and Reading Diagnosis Test(Fallahchay) were used before and after training. In addition the experiment group received phonological awareness training.

The results revealed that phonological awareness skills training could increase reading skills in comprehension and not word-recognition.

This study stress that training phonological awareness can improve reading abilities.
