Objectives: Most studies have performed to identify the affective variables in using mobile phone by drivers based on interview and questionnaire. In this study call answering rate while driving was investigated in a sample of male postgraduate students of a university in Tehran by a driving simulator. Methods: Six driving scenario designed differing in risk of driving. Answer rate to mobile...

Key posture design is commonly needed in computer animation. This paper presents an automatic and interactive whole body posture designing technique by combining the PIK (prioritized inverse kinematics) with the proposed parametric human posture splicing technique. The key feature of PIK is that the user can design a posture by adding high level constraints with different priorities. However, t...

Background: The supine head-down tilt position is routinely used in intensive care when inserting a central venous catheter to increase the lumen of the jugular or subclavian vein and to prevent air embolism during this procedure or to correct severe hypotension. The head-down tilt position is credited to the German surgeon Friedrich Trendelenburg (1844–1924), and is consequently named after hi...

alzheimer's disease (ad), a common and debilitating neurodegenerative disorder, affect more than 65 million individuals throughout the world. this disability plays a crucial role in daily activities such as driving. several studies have investigated the relationship between cognitive functions and driving safety. the current study revises the literature on the relation between road safety ...

Recently, self-powered flexible sensors have shown important application value in sports training. Thus, we design a triboelectric nanogenerator based on PET/Graphite composite film (PG-TENG) to harvest human motion energy and monitor football player leg muscle health. The polytetrafluoroethylene (PTFE) PET/graphite serve as the pairs; meanwhile, also plays role of conductive electrode. Moreove...

purpose: to determine the effect of horizontal recti surgery on visual acuity and head posture and electronystagmographic indices in patients with congenital nystagmus. methods: this prospective comparative case series was conducted on 58 patients with congenital nystagmus who were referred to our clinic over three years. patients were divided into three groups: the first group (29 cases) had h...

original article   health, safety, and environment management are dedicated a vast area in which ergonomics aspects known as one of the related aspects. in the following case study, the occupational hygiene by ergonomic intervention is focused. one of the prevalent activities among industrial sectors' workers in the developing countries is manual lifting tasks and other related physical activit...

objectives: the aims of this study were to evaluate the efficacy of conservative treatment in patients with and without cervical ribs and thoracic outlet syndrome (tos). from so many kinds of conservative treatment in literature, we used a multidisciplinary approach (correction of posture, maximizing muscle endurance and power, stretch shorten muscles, massage for trigger points and maximize th...

The objective of this study is to predict the behaviors of the human body in pre-crash conditions based on the experiment with active human models. In order to simulate the actual pre-crash condition of a car that occurs when the drivers brakes or pre-crash safety system activates in an emergency situation, low speed front impact tests on human volunteers were conducted using a sled-mounted rig...
