BACKGROUND: Telework has been widely studied by public and private organizations; however, in ergonomics, studies that focused on this topic are still sporadic. OBJECTIVE: Thus, this article endeavours to systematize the qualified scientific research related to ergonomics and teleworking to determine the main benefits and disadvantages and to identify the main issues addressed by authors. METHODS: A thorough research was conducted in the Scopus/Embase and Web of Science databases for this review. The following descriptors were used for the cataloguing of articles: “teleworking”, “telecommuting”, “telecommuters”, “home office”, “ergonomics” and “human factors”. 36 studies were selected. RESULTS: The study highlights four relevant questions in the scientific literature: a) where is the discussion of these themes consolidated; b) what are the main descriptors related to the discussion; c) which journals and conferences establish a scientific debate on the topic; and d) what are its main advantages and disadvantages. CONCLUSIONS: Results suggest that telecommuting can be a valuable tool for balancing professional and family life, which helps to improve the well-being of workers; however, several factors can influence the overall remote working experience which leads to the need for companies to adopt unique strategies reflecting their unique situation.
Background In the hospital environment, to achieve an optimum level of operations and service, it is necessary to develop adequate inventory management system. Stocks can be managed, amongst other ways, through inputs classification, which is generally carried out based on a single criterion, such as monetary value, demand or criticality, which does not fully address the complexity of a hospital’s inventory management system. Thus, the present study proposes a multi-criteria decision support model to help classify the stock of medicines and materials, enabling a more effective inventory management system for hospitals. Methods Methodologically, the study followed 3 stages: (1) preliminary phase; (2) modelling and choice phase; and (3) finalization phase. Each stage had a set of specific steps that were followed. The first stage identified the actors of the process, objectives, criteria and alternatives, establishing 5 criteria and 48 alternatives; the second stage was the choice and execution of the multi-criteria decision method to solve the problem. It was decided to use the Flexible and Interactive Tradeoff method for the sorting problematic. Finally, in the third stage, the sensitivity analysis for the developed model and the validation of the results with decision makers were carried out. In the study, 48 medicines and materials were included to validate the proposed model; however, the model could be used for more items. Results From the total of 48 medicines and hospital medical materials selected for the study, the classification of 34 of these alternatives to a single class was obtained through modelling and the other 14 alternatives were destined to two possible classes; moreover, the sensitivity analysis performed showed robust results. The items classified in class W should receive special attention by the stock manager; therefore, they should be monitored weekly. Items classified in class B should be monitored biweekly and finally, items classified in class M, should be monitored monthly. Conclusions The classification of medicines and materials developed according to the inventory demands allowed more efficient purchasing decisions, optimizing the stock of materials and medicines at the hospital while optimizing the inventory manager’s activities, saving time. Consequently, the proposed model can support the development of other multicriteria models in different hospital scenarios.
BackgroundThe growth of the urban population exerts considerable pressure on municipalities’ public managers to focus their attention on providing emergency medical care that meets the growing demand for emergency pre-hospital medical care. Currently, there are a significant number of traffic accidents and other serious occurrences, such as heart attacks, drownings, epidemics, fires and disasters (floods, landslides, earthquakes) that demand a prompt and seamless response from pre-hospital medical care. As a result of such scenario, the present article endeavours to apply a dual-coverage mathematical model (DSM-Double Standard Model) to define the optimal location of the Emergency Medical Service (SAMU) decentralized dispatch bases in Natal / RN and conduct a simulation study to evaluate the displacement of ambulances between such bases. Patients and methodsThe methodological course that was followed by this research constitute for 12 steps, so as to the location of decentralized bases for sending emergency ambulances was established using the DSM model and the simulation model was performed using the FlexSim software© version 2018 evaluating base coverage in relation to the total number of calls by demand points for different scenarios.ResultsThe results obtained throughout the research demonstrated the feasibility of redefining the decentralized bases of SAMU / Natal ambulances as a strategy to reduce response time and guarantee compliance with performance parameters established by international organizations (the World Health Organization, for instance, establishes the time of 8 minutes for emergency medical service calls response). The simulation study showed a significant reduction in response time, by up to 60% in some cases.ConclusionThe proposition of new locations for the decentralized dispatch bases of the SAMU/Natal can provide an overall significant reduction on the ambulance response time, so as to contributes to expedite the initiation of treatment of patients, if necessary, sent to hospitals.
Abstract:The Brazilian companies have crossed geographic borders, commercially and also culturally in search of longevity for their products and services. This study aimed to evaluate the impact of the strategic factors and the product innovation on the exporting performance in a candy confectionary company. In this regard, it has been analyzed the internationalization strategies used by the company, through quantitative and qualitative methods by application of a survey and interviews which, together, enabled to compare the importance and the performance of various attributes considered decisive to the exporting performance. Among the achieved results, this work showed there is a gap between the degrees of performance versus the degrees of importance of the studied attributes. This means that, by top management perspective, the company is below market expectation. It evidences the necessity for reevaluation the strategic planning, in order to strength other important dimensions explored, aiming to achieve success in the international market. This study confirmed the existence of a strong relationship between innovation product, strategy and exporting performance.
