Psychometric properties of the physical environment problems and barriers scale in older adults' homes using an ergonomic approach.

Background: As older adults prefer to live in their homes, it is of paramount importance to examine the adaptation of the environment to the older adults' capabilities.

Objective: The aim of this study was to develop and evaluate psychometric properties of a scale to measure physical environment problems and barriers in older adults' homes using an ergonomic approach in Iran.

Methods: This mixed-method investigation was conducted in two stages in Yazd, Iran.

Development and psychometric assessment an instrument for investigating Women's attitude toward home safety.

Background: Approximately half of the Iranian population are women, and they play a vital role in the home. The women's attitude can play a critical role in the safety of homes. Best of our knowledge, there is not a valid and reliable instrument to measure their attitude toward home safety.

Identifying barriers and problems of physical environment in older adults' homes: An ergonomic approach.

Background: The main purpose of ergonomics is environment adaptation to humans, and the root cause of the barriers and problems of the older adults is the mismatch between the home environment and their limitations.

Objective: The present study aimed to identify and explain physical environment barriers and problems among older adults' homes in Yazd, Iran.

Myoelectric Activity of Individual Muscles Variation by Differing Seat Pan Depth.

Background: The chair influences the position of the user in relation to his or her devices. Prolonged static sitting is a frequently mentioned risk factor for low back pain. Seat design, thus, plays an important role in the study of human sitting.

Impact of Psychosocial Factors on Occurrence of Medication Errors among Tehran Public Hospitals Nurses by Evaluating the Balance between Effort and Reward.

Background: Patient safety and accurate implementation of medication orders are among the essential requirements of par nursing profession. In this regard, it is necessary to determine and prevent factors influencing medications errors.

Determining optimum seat depth using comfort and discomfort assessments.

The aim of this study was to determine optimum seat depth using subjective assessments. Comfort and discomfort evaluation, as an ergonomic subjective method, was used to find the optimum seat depth. A total of 36 university students rated the comfort and discomfort of six different seat depths (including 32.

Electromyographic Activity of Soleus and Tibialis Anterior Muscles during Ascending and Descending Stairs of Different Heights.

Background: The aim of this study was to evaluate the electromyographic (EMG) activity of the two leg muscles (Tibialis anterior [TA] and Soleus [SOL]) during ascending and descending stairs with different heights (10 cm, 15.5 cm and 18 cm).

Methods: Eighteen female university students aged between 20 and 36 yr participated in the study.

Feasibility of magnetic resonance imaging (MRI) in obtaining nucleus pulposus (NP) water content with changing postures.

Opportunities to evaluate spinal loading in vivo are limited and a large majority of studies on the mechanical functions of the spine have been in vitro cadaveric studies and/or models based on many assumptions that are difficult to validate. The purpose of this study was to investigate the feasibility of magnetic resonance imaging (MRI) in obtaining nucleus pulposus (NP) water content measurements with changing postures. MRI studies were conducted on 25 healthy males with no history of low back pain (age 20-38).

Student's Body Dimensions in Relation to Classroom Furniture.

Background: This study was carried out to investigate the fit between university student's anthropometry and classroom furniture dimensions.

Method: In this cross-sectional and descriptive-analyzing study conducted in 2012, a total of 194 students (aged 18 through 30 years), were recruited randomly from Tabriz University of Medical Science community. The body size of each student was assessed using anthropometric measurements including shoulder height, elbow height, popliteal height, buttock-popliteal length, hip breadth and distance between elbows.

Working Conditions in Carpet Weaving Workshops and Muscu-loskeletal Complaints among Workers in Tabriz - Iran.

Background: Carpet weaving operations usualy involve poor working conditions that can lead to the development of musculoskeletal disorders (MSDs). This study investigated MSDs among car¬pet weavers in relation to working conditions from workers' view in Tabriz City, Northwest Iran.

Methods: This cross-sectional and descriptive study was conducted in city of Tabriz, Iran.

Reality about migration of the nucleus pulposus within the intervertebral disc with changing postures.

Background: Previous studies reported that, in non-degenerate discs, the nucleus pulposus migrates posteriorly during flexion and anteriorly during extension within the intervertebral disc. However, in these studies the differences between anterior and posterior distances have been regarded as an indicator of nucleus pulposus migration. This study investigated the reality of migration of the nucleus pulposus within the intervertebral disc with changing postures.

E-waste management challenges in Iran: presenting some strategies for improvement of current conditions.

E-waste is one of the fastest-growing waste streams in Iran, owing to an increase in consumption of electrical and electronic equipment. Nevertheless, as is the case in some other countries, E-waste management has not received sufficient attention. For the successful implementation of any waste management plan (including an E-waste management plan), the availability of sufficient and accurate information on the quantities and composition of the waste generated and on current management conditions is a fundamental prerequisite.

Characteristics of unintentional carbon monoxide poisoning in Northwest Iran--Tabriz.

The study describes the epidemiology and characteristics of unintentional carbon monoxide (CO) poisoning in Northwest Iran between 2007 and 2009 using multiple data sources including records of the main provider of emergency medical transportation, death certificate reports of the Legal Medicine Organization and through household surveys. A total of 1005 people were diagnosed with non-fatal CO poisoning. Ninety deaths were confirmed due to CO exposure.

Unintentional carbon monoxide poisoning in Northwest Iran: a 5-year study.

This paper describes the epidemiology of unintentional carbon monoxide (CO) poisoning in Northwest Iran between 2003 and 2008. Data were obtained from the records of the main provider of emergency medical transportation and from death certificate reports of the Legal Medicine Organization. During the study period, a total of 3078 hospital admissions were recorded against which 346 deaths were due to unintentional CO related poisoning caused by gas appliances in the homes.
