Oportunidades de melhoria ergonômica das exigências físicas da atividade jangadeira em Ponta Negra Natal-RN

The fishing is an activity with rafts marked by unpredictability, poor tools, physical stress, awkward postures, risk of accidents and incidents, which contribute to insecurity in the context of activity. This study aimed to contribute to reducing of physical effort and the biomechanical impacts in jangadeiro activity of artisanal fishing using jangadas on the beach of Ponta Negra, Natal-RN. To achieve this purpose the methodology of the Work Ergonomic Analysis - WEA became a reference using techniques such as observational and interactional observation notes, photographs, videos, action conversational and listening verbalizations. The resulting activity in health jangadeiro, discussed in this research were: static postural assessment, flexibility of movement of shoulder flexion-extension, flexibility of the hamstrings and lower back, grip and musculoskeletal pain. It was found from observations, interactions and activity analysis, that in carrying out fishing rafts are frequent awkward postures associated with demand for power and many are already feeling the jangadeiros reflections of years of life dedicated to this work. These have already adopted some measures to manage the activity, such as job rotation during the expedition of capture. Therefore, there is a need to expand these measures of activity management, as well as design and capabilities of the raft, seeking positive changes in the activity and consequently the quality of life jangadeiro

Modelagem situada de metodologia da oficina de desenho de renda de bilros

The bobbin lace, a secular art in the process of extinction in the Village Ponta Negra in Natal, Brazil, was one of the main means of income generation for some families in town, but over time, there was growing disaffection of the younger generation to learn and practice this art, due to the high demand of time for production and insufficient and not guaranteed financial return . This project aims to promote the recovery of control over the product in the production of bobbin lace in the village of Ponta Negra, by design and implementation of a workshop for the transfer of drawing techniques in the Production Center of Craft in Village of Ponta Negra. This design was based on the methodology of Ergonomic Work Analysis and in the concepts of anthropotechnology and technology social. The ergonomic analysis, by advocating and enforcing the social and technical building, was essential for the modeling of this workshop, as allowed the construction of a social participative device , with the participation of the community groups and the external group of researchers, in a process of social construction technique. As a result, it was observed that the transfer of technical design of bobbin lace molds came to complement the learning of art office, providing solutions to promote the sustainable development of the group of tenants, in an attempt to reduce the risk of extinction eminent, and also contributed to reactivate a network of economic activities interconnected to the craft, such as the production of cushions, lace and easels

Abordagem da ergonomia para análise da acessibilidade a hóspedes com deficiência visual em hotéis: soluções de inclusão de pessoas cegas e com baixa visão

This study evaluates the level of accessibility for people with visual impairment (blindness and low vision) hotels in the city of Natal-RN, Brazil, and provides principles, guidelines and means of projective make hotels accessible, to promote comfort, autonomy and security of these people. We used a qualitative research methodology and quantitative trait descriptive, analytical and interpretive. Was taken as a base for field studies Ergonomic Analysis of Work, beginning with a study of the demands of accessibility of hotels and analyzing the modeling activity in these establishments through the application of interactional and observational techniques, such as film, photographic records, conversational actions and observation protocols. A protocol was developed and applied to evaluate the compliance of accessibility of hotels in the face of Brazilian technical standard NBR 9050 (2004). We used methods of Cognitive Task Analysis (CTA) associated with simulated activities to identify the processes of decision making and analyzing the observables of the activities performed by people with visual impairment (POS). Interviews were conducted with people who are blind and low vision in various cities in order to meet accessibility difficulties they faced in hotels and recommendations for improvement that they indicate. The mapping results showed that of 16 hotels 4 and 5 star studied in Natal-RN, reached only 7% of the 50 items of the protocol, while none of them reached 70% of the items. About the results obtained in simulated activities and analyzed from the ATC, we saw that the hotel where it was performed this step shows a need to adequately address the guests with visual impairments

Uma abordagem ergonômica para análise da qualidade do pescado, desde sua captura ao seu desembarque na praia, resultante da atividade dos jangadeiros de Ponta Negra - Natal/RN

The artisan fishing activity, which involves historical - cultural, environmental, social, political, economi c, among other factors, presents, nowadays, as an important source of income, creating jobs and food, contributing to the permanence of man in their own birthplace. However, the fish, considered one of the most perishable foods, requires a proper handling and conservation, from capture to its availability in the market, in order to slow the deterioration process. Thereby, this dissertation aims to study the effect of the manipulation practices on fish quality, from capture to its landing on the beach, resul ting from fisherman’s activity from Ponta Negra - Natal/RN. It also presents the purpose of analyzing the quality of the fish and propose recommendations for their proper handling and possible solutions to add value to the product, through the improvement of the quality and good handling practices. For this purpose, the methodology used was based on ergonomic analysis of their work through observational techniques and interactional with the focus group, the jangadeiros, to understand their activity and eval uated the freshness and quality of the fish by sensory analysis, and microbiological parameters and physicochemical from existing legislation Ordinance No. 185 of May 13, 1997 and RIISPOA - amended on December 1, 2007 and RDC No. 12, dated January 2, 2001. According to the results obtained in laboratory tests, it can be established, the acceptable quality of fish as the existing rules and regulations parameters , not getting significant deterioration caused by poor handling and improper storage of fish.

Análise da atividade cognitiva do operador de sala de controle da produção de controle da produção de petróleo on-shore: uma abordagem da ergonomia para a gestão das restrições do sistema sociotécnico

This master's thesis aims to analyze the activity of the operators in a control room of the processes of production on-shore petroleum, with a focus on sociotechnical restrictions that interfere in the decision-making process and the actions of operators and therefore, the strategies (individual and collective) to regulate and maintain the operator action required and the safety of the system, together. The activity in focus involves the supervision and control of the production of thousands of barrels of oil/day in a complex and dispersed production’s structures built in an extension of 80 km. This operational framework highlights the importance of this activity for the fulfilment of the targets local and corporate efficiency, good management of the environment, health and safety of operators. This is an exploratory research and in the field, which uses the methodology of Ergonomic Analysis of the Work, composed of observational techniques and interactional, having as locus control room of the processes of production on-shore oil of an oil company. The population of this research is formed by operators in the control room of an Brazilian oil company. The results showed that the supervisory activity and control of the superheated steam injection is an complex context, demands greater attention, concentration, calculations, comparisons, trend analysis and decision making. The activity is collectively constructed between the control room operator, field operator and the supplier of steam. The research showed that the processes of communication and collaboration between the control room , fields and support staff are the key elements of this activity. The study shows that the operators have the autonomy and the elements necessary for work; and that there is continuous investments to improve the technology used and that the operators report sleep disturbances as a result of chronic exposure to night work. The study contributed with proposals for transformation of this activity: with regard to the installation of a area reserved for food in control room, the update the screens of the supervisory current operating condition, the periodic visits by room operators in the field, standardization of production reports, development assistance and standardization of nomenclature of controlling stations steam systems, to improve the conditions of realization of the activity, improve the quality of products produced by operators and contribute to reduce the possibility of slips or shifts in the activity.
