Cognitive-ergonomics and instructional aspects of e-learning courses

This paper presents an analysis of cognitive-ergonomic aspects of e-learning courses, offered by an organism from Brazilian Public Administration. The Cognitive Ergonomic studies conductive and cognitive aspects concerning to the relation between human, physics elements and social elements of the work space. From that usability aspects were evaluated by these points: i) visualization; ii) text comprehension lecture; iii) memory; iv) interface; v) instructional design; and vi) attention and learning. That survey is characterized as having been applied using the following techniques: (1) bibliographic survey, (2) field survey and (3) analysis of the documents. It was chosen the semi-structured questionnaire as the main method of data collection. About the interacting with artifacts, the interface of the courses is classified as direct engagement, because it allows the user to get the feeling that acts directly on the objects. Although the courses are well-structured they have flaws that will be discussed below. Even with these problems, the courses have a good degree of usability.     

Construction and application of an indicator system to assess the ergonomic performance of large and medium-sized construction companies

This article proposes a system of indicators to evaluate the performance of companies in ergonomics for buildings. The system was developed based primarily on studies related to the performance evaluation of the construction industry and on Brazilian standards of ergonomics and work safety and had also the contribution of national and international indicators related to ergonomics, work safety, quality, sustainability, quality of work life and to organizational behavior. The indicators were named, classified and their components were assigned to compose the theoretical model SIDECE--System of Performance Indicators in Ergonomics for Building Construction (as for the Portuguese acronym), serving the major goals of ergonomics: health, safety and workers' satisfaction and production efficiency. The SIDECE is being validated along with the building construction companies in the city of Natal, Brazil, whose practical results, deriving from the application of instruments to collect field data, are under process, to be presented on the occasion of the 18th World Congress on Ergonomics. It is intended that the SIDECE be used by building construction companies as a support tool for excellence management.     

Evaluating work and training within an intercommunicating process of change: reflections drawn from a case study on a chemicals industrial company in Portugal

The new challenges in the field of Health and Safety at Work require the implementation of more comprehensive and participatory interventions, in order to have a real impact on the working conditions. Matriosca Model has sought over the years to involve workers in the construction of new working conditions, promoting transformation through training and recreating training from the transformation. This article seeks to present some of the results of the implementation of the Matriosca Model on a chemicals industrial company regarding the many changes that it promoted, how these changes have evolved through time, how the dimensions of training and transformation interact and what the participants' perception of the intervention was. The conclusions drawn allow a richer evaluation of the process, which can enhance the intercommunicating nature between training and transformation, and what impact this has on the actual work.     

When gender bumps into health and safety training: working conditions, readings and challenges drawn from a case study in an industrial chemicals company

Health, safety and environmental issues are at present a social concern and an increasingly referred topic in the so called gender studies. This paper focuses on the relations between training, gender and risk perception in an industrial chemicals company, in Portugal, characterized by a mainly male population and by the presence of high occupational and environmental hazards. After characterizing the company and the training project that started up this reflection, the paper presents the reasons for its focus on gender followed by the essential methodological explanations: 14 interviews were made with male and female workers from the company; their content was transcribed from the audio recordings and it was systematically analyzed. A gender-attentive socio demographic analysis was also undertaken. Although at the beginning the company did not consider the gender issues as a problem nor was it the central topic of the training, which focused on the prevention of occupational and environmental hazards, the results reveal that the gender factor brought to light some working conditions, which so far have not been properly discussed within the group meetings. As a consequence, there is now room for the transformation of the representations on those working conditions.     

Assessment of physical workload in boiler operations

The use of boiler wood-fired is fairly common equipment utilized in steam generation for energy production in small industries. The boiler activities are considered dangerous and heavy, mainly due to risks of explosions and the lack of mechanization of the process. This study assessed the burden of physical labor that operators of boilers are subjected during the workday. Assessment of these conditions was carried out through quantitative and qualitative measurements. A heart rate monitor, a wet-bulb globe thermometer (WBGT), a tape-measure and a digital infrared camera were the instruments used to collect the quantitative data. The Nordic Questionnaire and the Painful Areas Diagram were used to relate the health problems of the boiler operator with activity. With study, was concluded that the boiler activity may cause pains in the body of intensity different, muscle fatigue and diseases due to excessive weight and the exposure to heat. The research contributed to improve the boiler operator's workplace and working conditions.     

Evaluation of thermal overload in boiler operators

The Brazilians educational institutions need a large energy demand for the operation of laundries, restaurants and accommodation of students. Much of that energy comes from steam generated in boilers with wood fuel. The laboral activity in boiler may present problems for the operator's health due to exposure to excessive heat, and its operation has a high degree of risk. This paper describes an analysis made the conditions of thermal environment in the operation of a B category boiler, located at a Higher Education Institution, located in the Zona da Mata Mineira The equipments used to collect data were Meter WBGT of the Heat Index; Meter of Wet Bulb Index and Globe Thermometer (WBGT); Politeste Instruments, an anemometer and an Infrared Thermometer. By the application of questionnaires, the second phase consisted of collecting data on environmental factors (temperature natural environment, globe temperature, relative humidity and air velocity). The study concluded that during the period evaluated, the activity had thermal overload.     

Ergonomics in designing process: dialogue between designers, executors and users in the maintenance activity of radars in an oil refinery

This paper aims to discuss the role of ergonomics in design process using the dialogue developed by designers, implementers and users in an oil refinery. It was possible to identify the need of minimizing the postural constraints, risk of accidents, mechanical shocks and to enlarge safety perception in the access and permanency of the users at the workspace. It has been determined and validated by workers and managers to implement different deadlines depending on programming, viability and execution time for the improvements proposed. In a long-term: it was proposed the substitution of the ladders with time planning according to the maintenance program of the tanks; in a short-time: it was suggested the expansion of the existing platforms, implementation of a walkway connection provided with guardrails between the upper access of the side ladder and the repositioning of radar set and aerial aiming at the usage by workers at the workstation of the new platform. It was also elaborated eight typologies of intervention, according to the request, type of tank, material stored, and its setting place. The design process arises from ergonomics workplace analysis that presents concepts for solutions which was a mediator tool to be settled between users and implementers.     

A program to support the construction and evaluation of resilience indicators

The main objective of this work is to propose a method and a tool to support the development of indicators able to inform an organization about the state of its resilience through a cyclical process of identifying its resilience factors, proposing resilience indicators, assessing its organizational resilience followed by assessing and improving the resilience indicators. The research uses concepts from complex adaptive systems and from resilience engineering to establish an initial set of indicators able to assess elements that contribute to organizational resilience, and structures them temporarily as a hierarchy. A software application to support indicator definition and structuring, questionnaire generation, and result assessment activities was built to assist in speeding up the experiment-adjust cycle. Prototype indicators were instantiated with helicopter operating companies in mind, and were reviewed by a domain expert.     

Development and validation of the Measure of Initial Attraction (MIA) / Elaboración y validación de la Medida de Atracción Inicial (MAI)

Unilateral Initial Attraction (UIA) is a first unilateral awareness towards an unknown person and can be the starting point of an interest in voluntarily initiating an interaction or relationship. In order to create a measure tapping this feeling, Study 1 asked individuals to indicate attributes characterizing UIA (Phase 1), and to rate their centrality (Phase 2). These were used to develop the Measure of Initial Attraction (MIA) comprising one component of arousal and another of unilateral interest. While the former is shared with the love construct, the latter differentiates from measures of passion. The MIA proved to be a valid and reliable instrument with the capacity to discriminate UIA across different relationships (Study 2) and targets (Study 3), with good convergent validity (Study 3). Results are discussed within the framework of personal relationships.     

Self‐employment among people with disabilities: evidence for Europe

This paper examines the use of self‐employment among people with disabilities in Europe. Using data from the European Community Household Panel for the period 1995–2001 for 13 European countries we found that people with disabilities were more likely to be self‐employed than people without disabilities. Self‐employment provides flexibility and a better adjustment between disability status and working life. Moreover, the levels of satisfaction with job, type of job and working conditions of self‐employed disabled people are higher than those reported by disabled people who are wage and salary earners. Policy‐makers must encourage self‐employment to increase the levels of well‐being and employment of people with disabilities in Europe.
