In order to achieve better postures and decrease musculoskeletal risks adequate design of hand/box couplings for manual materials handling (MMH) are still needed. No studies evaluating upper limb movement thorough direct measurements during box handling in workplace were identified in the literature. In this study we describe the types of grip and movements adopted by ten workers when handling redesigned boxes with cutout handles between different heights on industrial pallets. The new handles were used by 90% of the workers through different types of grip. Electrogoniometric measurements showed relatively safe forearm and wrist movements, although elbow inadequate range of movement was recorded. Despite the good acceptance of the cutout by workers, the new design requires extra internal space in the boxes reducing applications for this alternative of box. 相似文献

Training and provision of assistive devices are considered major interventions to prevent and treat low back pain (LBP) among workers exposed to manual material handling (MMH). To establish the effectiveness of training and provision of assistive devices in preventing and treating LBP an update of a Cochrane literature review was performed to November 2010. Randomised controlled trials (RCTs) and cohort studies with a concurrent control group (CCTs) were included. Nine RCTs (20.101 employees) and nine CCTs (1280 employees) were included for prevention: six more than in the previous version. No study on treatment was found. None of the included RCTs and CCTs provided evidence that training and provision of assistive devices prevented LBP when compared to no intervention or another intervention. 相似文献

The aim of the study was to visualize design regulations of furniture by means of interactive technology based on earlier studies and practical examples. The usage of the visualized regulations was evaluated on two occasions: at the start when the first set of regulations was presented, and after six years of usage of all regulations. The visualized regulations were the result of a design process involving experts and potential users in collaboration with IKEA of Sweden AB. The evaluations by the different users showed a very positive response to using visualized regulations. The participative approach, combining expertise in specific regulations with visualization of guidelines, resulted in clear presentations of important regulations, and great attitudes among the users. These kinds of visualizations have proved to be applicable in a variety of product areas at IKEA, with a potential for further dissemination. It is likely that the approaches to design and visualized regulations in this case study could function in other branches. 相似文献

Everson MD Sandoval JM Berson N Crowson M Robinson H 《Journal of child sexual abuse》2012,21(1):72-90
In the absence of photographic or DNA evidence, a credible eyewitness, or perpetrator confession, forensic evaluators in cases of alleged child sexual abuse must rely on psychosocial or "soft" evidence, often requiring substantial professional judgment for case determination. This article offers a three-part rebuttal to Herman's (2009 ) argument that forensic decisions based on psychosocial evidence are fundamentally unreliable and that this conclusion represents settled science. The article also discusses the potentially adverse consequences of Herman's proposed reforms to forensic practice on child protection and prosecution efforts. 相似文献

This work proposes a design methodology using ergonomics and anthropometry concepts applied to traffic sign and street name sign projects. Initially, a literature revision on cognitive ergonomics and anthropometry is performed. Several authors and their design methodologies are analyzed and the aspects to be considered in projects of traffic and street name signs are selected and other specific aspects are proposed for the design methodology. A case study of the signs of "Street of Antiques" in Porto Alegre city is presented. To do that, interviews with the population are made to evaluate the current situation of signs. After that, a new sign proposal with virtual prototyping is done using the developed methodology. The results obtained with new interviews about the proposal show the user satisfaction and the importance of cognitive ergonomics to development of this type of urban furniture. 相似文献

A company making women's clothing, located in Belo Horizonte, Minas Gerais was studied in its ergonomic aspects with regard to the layout. With this study it was possible to establish the best positioning of machines and jobs of employees. The analysis criteria used were: frequency of use, functional grouping, sequence of use, flow and intensity of preferred connections. An ideal arrangement in the workplace provides improved manufacturing quality and employee performance and consequently higher production yields. 相似文献

This present article describes a research on the development, under the approach of participatory design, a virtual teaching-learning of Histology in which students and teachers participated actively in all stages of development of the educational environment. We postulates that the development of virtual learning environment of Histology, through the Participatory Design approach, contributes to greater acceptance and use by students and that the adoption of virtual environment for teaching and learning by teachers is a determining factor of use by students. 相似文献

This article studies the voters of DENK, the first immigrant party to gain seats in a national parliament. It builds further on the existing literature on how immigrants and people from immigrant descent vote in Western European countries. From the literature we derive seven expectations about the kind of voters that are likely to vote for an immigrant party in terms of their political cynicism, attitudes towards economic, globalisation and moral issues. We find that DENK voters are younger Muslims, who have conservative views on moral matters, cynical attitudes towards politics, right-wing views on economic matters and progressive views on issues that pertain to the globalisation dimension, such as immigration, integration and Islam and in particular discrimination. This article uses VAA data to construct a matched sample that in terms of key variables is representative for voters with and without a migration background. 相似文献
