In the lives of the elderly, work and the related socio-economic conditions are a significant, and often essential, part of life. The quality of life is a cumulative and multifactorial indicator. Therefore, to evaluate it, macroergonomic analysis is particularly applicable. Quality of life is thus an aggregating factor, which generally describes factors in an undoubtedly subjective manner. Currently existing methods propose to ask questions about the quality of working life in categories such as: wages, incentive systems, relations with supervisors and co-workers, market position of the company, opinions on the organization expressed by others, and organization and nature of the work. However, the evaluation of individual categories helps to a small extent to identify particularly important systemic relationships as well as expectations directed at the technical and organizational environment. Therefore, this paper presents a synthesis of methods, utilizing, among others, Macroergonomic Organizational Questionnaire Survey (MOQS), Karasek’s Job Content Questionnaire (JCQ), NIOSH Job Stress Questionnaire and NASA Task Load Index. This combination results in a research tool that not only assesses the fulfilment of each category, but also recognizes the needs of people surveyed in the specific areas.
<p>Operadores humanos responden a alarmas en condiciones normales y también en situaciones inesperadas y anormales en tiempo real. El objetivo de este estudio consiste en aumentar el conocimiento de las reacciones humanas a alarmas en el ámbito laboral. Describe como los humanos pueden contribuir a accidentes y presta atención a la seguridad del proceso que se efectúa en el tiempo de reacción a las alarmas de sistema. Este experimento fue ejecutado para investigar si hay diferencias en respuestas diferenciales a alarmas visuales comparándolas a alarmas auditivas. Los resultados indican que las alarmas visuales son percibidas de manera más eficiente que las alarmas auditivas. Incluso, se pudo ver una correlación negativa entre la cantidad de errores y el tiempo de reacción, lo que indica una diferencia individual en su disposición a errores cuando reaccionan a alarmas visuales en operaciones de supervisión.</p>
