BACKGROUND Dystocia is one of the important causes of maternal morbidity and mortality in low-income countries. This study was aimed to determine the diagnostic accuracy of maternal anthropometric measurements as predictors for dystocia in nulliparous women. MATERIALS AND METHODS This prospective cohort study was conducted on 447 nulliparous women who referred to Omolbanin hospital. Several m...

This thesis gives an overview of the research of a system that generates a 3D model of a human head from 2D images. The location and size of the eyes, eyebrows, nose and mouth in 2D orthogonal images are detected using skin color detection, template matching, value detection and a anthropometric model. The results of these detections are combined for more robust results. Manual initialization i...

The purpose of this study was to determine pillow designs suitable for supine and side-lying positions. [Subjects] Twenty female and twenty male subjects with a mean age of 22.7 years (SD = 1.3) participated in the study. [Methods] First, a three-dimensional motion analysis system was used to analyze the movements of the head and the shoulder joints during changes from supine positions to side-...

Purpose: The aim of this study was to compare head and neck alignment in children with visual and hearing impairments and its relation with anthropometrical parameters. Methods: The study was a descriptive, correlational analysis within which the relations between dependent and independent variables have been studied. Thirty children with poor vision, 30 children with hearing loss and fina...

background: increased requirement and decreased dietary intakes of micronutrients during pregnancy might affect maternal health and pregnancy outcomes. this study was aimed to examine the effects of two types of multiple micronutrient supplementations on pregnancy outcomes in kashan, iran. methods: in a randomized single‑blind controlled clinical trial, 104 primigravid singleton pregnant women ...

abstract in order to evaluate the effects of drought stress and defoliation on sunflower, a study was conducted under controlled conditions. treatments were a combination of three levels of drought ((100, 60 and 30 percent of field capacity (fc)) and three levels of defoliation (control, removal of either 4 or 6 leaves from lower part of the plant) laid out, in a completely randomized design wi...

BACKGROUND It is impossible to give an objective anthropologic assessment of the overall physical development of a child's body during the time of intensive growth (7-17 years) without taking into account the age and gender changes in the absolute and relative head and face measurements. Head growth has specific characteristics that makes it different from the growth of other parts of the body....

BACKGROUND Paralysis of the common peroneal nerve is one of the relatively common nerve injuries related to the lithotomy position with the use of a knee-crutch/leg-holder system. Several risk factors have been implicated in lithotomy position-related common peroneal nerve paralysis during operation. MATERIALS AND METHODS In the present study, 21 young healthy volunteers participated in the i...

To investigate the effects of vehicle impact velocity and front-end structure on the dynamic responses of child pedestrians, an extensive parametric study was carried out using two child mathematical models at 6 and 15 years old. The effect of the vehicle impact velocity was studied at 30, 40, and 50 km/h in terms of the head linear velocity, impact angle, and head angular velocity as well as v...

A case of 28-year-old man with closed fracture dislocation of the radial head following a fall from height is reported. He was treated with radial head excision. The radial head is an important stabilizer of the elbow, thus the rationale of radial head excision in management of radial head fractures should be scrutinized. There is much debate regarding the optimal treatment for these fractures.
