The role of demographic, job-related and psychological characteristics on the prevalence of repetitive patient safety incidents among Iranian nurses.

Background: Job-related psychosocial factors have a substantial effect on the occurrence of adverse events among healthcare professionals.

Objective: An analytical and descriptive survey was conducted to evaluate the relationship between the occurrence of patient safety incidents and psychological factors.

Methods: The study sample consisted of 177 nurses who were asked about patient safety events over six months.

Improvement of natural fiber's properties and evaluation of its applicability as eco-friendly materials in noise pollution control.

Purpose: The use of green and eco-natural fibers due to availability, biodegradability, reasonable cost, and non-toxic effects are known as potential acoustic materials in research. Nevertheless, in this area, the use of chemical treatment in natural fibers as an effective strategy to improve the overall properties and acoustic performance is faced with limitations. So that the current paper aims to investigate the effect of alkali treatment on the mechanical and acoustical properties of jute fibers and evaluation of its applicability in noise pollution control.

The effect of traffic noise on cognitive performance with regard to personality traits: A laboratory experiment study.

Background: Exposure to traffic noise could play an important part in inducing psychological disorders which in turn can affect individuals' cognitive and mental performance.

Objective: The aim of this study was to determine the effect of traffic noise exposure on the cognitive performance with regard to subjects' personality traits.

Methods: Sixty students with normal hearing and vision took part in this experimental study.

Morphological, acoustical, mechanical and thermal properties of sustainable green Yucca () fibers: an exploratory investigation.

Background: The objective of this study was to evaluate the acoustical, morphological, mechanical and thermal properties of fibers extracted from the leaves of Yucca () shrub.

Methods: Several tests were performed on either untreated or alkali-treated (5% NaOH) fibers. The chemical analysis of the fibers was performed to determine their lignin, cellulose, hemicellulose, wax and moisture content.

Relationships Between Job Satisfaction and Job Demand, Job Control, Social Support, and Depression in Iranian Nurses.

Background: Nurses often experience a wide variety of stressful situations. Excessive work stress influences the physical and mental health of nurses and decreases their life quality and professional efficacy. In addition, high levels of psychological stress may cause job dissatisfaction and job strain.

Experimental and mathematical survey of sound absorption performance of date palm fibers.

The present study examines the acoustic behavior sample composites made of date palm natural fibers and polyvinyl alcohol. It also provides the comparison between the sound absorption coefficients obtained from the experimental tests and the ones predicted by the mathematical models. An impedance tube system was used to measure the normal sound absorption coefficient of the samples.

Role of Psychosocial Job Stressors on Sexual Function of Male Nurses: The Mediator Role of Work Ability.

There is limited information on the specific psychosocial risks at work that can impact sexual function. The general aim of this study was to investigate the effects of multiple dimensions of psychosocial work stressors on the male sexual function. This was a cross-sectional study conducted among 153 male nurses working in two hospitals in Iran.

Investigation of outdoor BTEX: Concentration, variations, sources, spatial distribution, and risk assessment.

The aim of this study was to measure BTEX (benzene, toluene, ethylbenzene, and xylenes) concentrations in the ambient air of Tehran, the capital of Iran, and investigate their seasonal variations, probable sources, spatial mapping, and risk assessment. The concentrations of BTEX were measured using a continuous monitoring device installed in seven stations around the city. Spatial mapping procedure was conducted using the inverse distance weighting (IDW) method.
