Analysis of working conditions focusing on biological risk: firefighters in Campo Grande, MS, Brazil

Firefighters are exposed to a wide range of risks, among them, biological risk. The objective was to analyze working conditions of firefighters in the city of Campo Grande, MS, Brazil, focusing on risk conditions of exposure to biological material. Three hundred and seven (307) firefighters were interviewed for data collection and observed for ergonomic job analysis (AET). Results: 63.5% of the firefighters suffered some kind of job related accident with blood or body fluids. Statistically significant association was found between having suffered accidents at work and incomplete use of personal protective equipment (PPE). About AET regarding the biological risks, 57.1% of all patients had blood or secretions, which corresponds in average to 16.0% of the total work time, based on a working day of 24 h. Besides biological risks, other stressing factors were identified: emergency and complexity of decision, high responsibility regarding patients and environment, and conflicts. Health promotion and accident prevention actions must be emphasized as measures to minimize these risks.     

Analysis of ergonomic furniture made of wood and sub-products from renewable forests

The furniture ergonomic evaluation was carried out through the use of questionnaires and forms in industries. For the ergonomic product analysis, it was used the methodology "Object Ergonomics - Ergonomic System Technical Reading" (design goals and management actions), and measurements of products. The values achieved were compared with the standard dimensions, and the compliance or non-compliance of the furniture to it was assessed. In relation to the dimensions of the bed, the following variables did not comply with the norms: external and internal length, external and internal width, height and width of the sidebar and distance to the floor. The dimensions of these variables were above the recommended values. The double bed was inadequate for management actions and maintenance. Since the kitchen cabinet is a product that went through physical testing and follows national standards; the finish used is powder coating. The kitchen cabinet proved to be appropriate in all design requirements and for management actions. Both furniture pieces were inadequate, considering the difficulty for maintenance when a product or part of it was damaged. It was recommended the creation of regulatory standards for the production of safe and comfortable furniture.     

Managing ergonomics in the development of rotation between workstations in the automotive industry. A balance between health and traceability of tasks

Abstract When the subject rotation between workstations (job rotation) is inside the organizations it's seemed that technically there are lots of restrictions to the development of an adequate system of rotation. We went from the need for an advanced ergonomic study and even possible restrictions of versatility and training of employees. The implementation of the ideal system of rotation passes through stages of development and research ergonomic study of the level of employee versatility, awareness and discussion with employees, implementation of the proposed system, feedback and audits for maintenance of the ideal sequence and time of rotation. For the success of the project there is a need for multidisciplinary involvement in the areas of manufacturing engineering, industrial engineering, human resources, medical services and manufacturing. Rotation between the tasks may mean that a worker should conduct two or more different activities in different parts of the day (ie. change between activity A and activity B "between 1 hours and 2 hours interval). An important consideration is to ensure that different activities do not present the same ergonomic risk for the same body part. The tracing of the execution of the activity is an important factor for production processes. Thus it is possible to conduct appropriate levels of training for employees and ensure safe and sustainable processes in terms of workers' health, productivity and quality.     

Measuring organizational effectiveness in information and communication technology companies using item response theory

The aim of this paper is to measure the effectiveness of the organizations Information and Communication Technology (ICT) from the point of view of the manager, using Item Response Theory (IRT). There is a need to verify the effectiveness of these organizations which are normally associated to complex, dynamic, and competitive environments. In academic literature, there is disagreement surrounding the concept of organizational effectiveness and its measurement. A construct was elaborated based on dimensions of effectiveness towards the construction of the items of the questionnaire which submitted to specialists for evaluation. It demonstrated itself to be viable in measuring organizational effectiveness of ICT companies under the point of view of a manager through using Two-Parameter Logistic Model (2PLM) of the IRT. This modeling permits us to evaluate the quality and property of each item placed within a single scale: items and respondents, which is not possible when using other similar tools.     

ERGOBERÇO® (Ergonomics Crib)--evaluation of the prototype for a adaptation to safety's variables and comfort

The crib is the infantile furniture more mentioned in infantile accidents. In spite of the existence of several models, many of them are not appropriate to their users and considered insecure. The objective of this study was to structure the prototype of ERGOBER?O?, considering technical norms and evaluation in loco of the prototype through structured interview answered by the participants of the research. The prototype was evaluated as safer, resistant and comfortable than the crib used by the mothers and participant users of the study. The aspects with larger acceptance index were the movable grating and the compact base, defined for the users as facilitators of the use and attribute of safety of the prototype. Even the prototype having been very appraised and accept for the users, it will be necessary to restructure the prototype so that the same can still be adapted more the users' needs, being, besides insurance and comfortable, with compatible aesthetic pattern with the expectation of these.     

A literature review about usability evaluation methods for e-learning platforms

The usability analysis of information systems has been the target of several research studies over the past thirty years. These studies have highlighted a great diversity of points of view, including researchers from different scientific areas such as Ergonomics, Computer Science, Design and Education. Within the domain of information ergonomics, the study of tools and methods used for usability evaluation dedicated to E-learning presents evidence that there is a continuous and dynamic evolution of E-learning systems, in many different contexts -academics and corporative. These systems, also known as LMS (Learning Management Systems), can be classified according to their educational goals and their technological features. However, in these systems the usability issues are related with the relationship/interactions between user and system in the user's context. This review is a synthesis of research project about Information Ergonomics and embraces three dimensions, namely the methods, models and frameworks that have been applied to evaluate LMS. The study also includes the main usability criteria and heuristics used. The obtained results show a notorious change in the paradigms of usability, with which it will be possible to discuss about the studies carried out by different researchers that were focused on usability ergonomic principles aimed at E-learning.     

Needs assessment of youths in residential child care in Portugal / Evaluación de necesidades de jóvenes en acogimiento residencial en Portugal / Evaluación de necesidades de jóvenes en acogimiento residencial en Portugal

Residential child care in Portugal is the most common protection measure in cases of family separation, since family foster care is still very rare. However, little is known about the needs of these children and young people. The purpose of this study is to describe the profile of adolescents close to legal adulthood who are in residential care, comparing it with a Spanish sample. The sample is composed of 345 young people aged 16 to 17 on whom information has been collected regarding their history of protection, family background, schooling, mental health and offending behaviour. A Spanish sample was selected as a comparison group (N = 384). The results reveal the complexity and special seriousness of the profile of young people in residential care in Portugal compared to a Spanish sample, highlighting a high presence of mental health problems and especially suicidal behaviours. Given these results, efforts should be focused on developing specialized residential care programmes adapted to the specific needs of these young people.     

Effects of Assertive Training on Trainees and Their Spouses*

The efficacy of training as a mode of treatment has been tried in many settings with a variety of populations. This study utilizes assertive training as a mode of treatment. The effects of a four-week assertive training program were measured by several instruments including the Hippie Interpersonal Relationship Rating Scale, Wolpe-Lazarus Assertive Inventory, and Content Inventory. Results indicate assertive training as having both positive and negative effects as perceived by trainees and their spouses. The variance in rating indicates the need to include a trainee's significant other in some phase of training.     

Migration and mental health: an empirical test of depression risk factors among immigrant Mexican women

Empirical research in the field of migration and mental health is rare and its recent appearance follows decades of inconsistent reports in the research literature about the risks posed by numerous precipitating and predisposing factors. This article has 2 goals: 1) to summarize critically selected issues and methodological problems regarding mental health implications of migration-adaptation, and, 2) to test empirically hypotheses derived from the Fabrega Migration Adaptation Model to determine whether they have predictive value for depressive symptomatology in a cross-sectional sample of Mexican immigrant women in San Diego county. Findings from bivariate analyses indicate most of the model's factors were significantly related to depressive symptoms. Multivariate analyses identified 1) demographic factors (education-income), 2) perceived economic opportunity, 3) perceived distance between the 2 centers involved in the migration, and 4) loss of interpersonal ties in Mexico as the most parsimonious subset of depression indicators within the model. Implications are discussed.
