Work accidents result in consequences to the employment of the population and increasing public spendings. Caused by workplace and work activity characteristics, occupational accidents may also derive from ergonomics and comfort issues. Heat stress is a discomfort factor that affects workers when exposed to temperatures above the body limits, resulting in exhaustion, dizziness, loss of concentration and, eventually, injuries and accidents. Under the current climate change scenario characterized by increase of temperature projections all around the world, the heat stress issue becomes even more significant. However, in Brazil, this topic is yet little explored, especially regarding the investigation of historical data on occupational accidents considering the climatic variables. The present study aims at filling a part of this gap by presenting a new database that unifies a work accident database - with over a decade of records - with meteorological data of the place and time of the accident. We investigate the relationship between these two datasets through the application of Multiple Correspondence Analysis on the database. Our results show some association between accident variables and heat stress variables. We identify some of the more critical workers' characteristics in this context and the most exposed regions of Brazil. Our database allows the continuity and expansion of this type of research in Brazil, and the MCA results point to a positive association between the occurrence of accidents with climatic variables. It may pave a new path for research that can detail and deepen the discussion on the behavior of these variables. © 2022, The Authors. All rights reserved.

The energy transition and reactivation of mature oil fields may even being seem as bipolar topics, within the theme of energy. However, regarding to the sustainability, these topics can be analyzed in parallel to the approach to the inherent risks involved in the supply chain, associated with energy transition. This study talks about the energy transition, connecting the risks associated with its implementation (focusing on supply chain) and discusses how adversely the promotion and reactivation of inactive areas are affecting or contributing to advances in sustainability discussions. Studies out of international agencies reports of energy and sustainability were made, also from organizational reports applied to the energy transition, and scenery analysis of the reactivation of producing oil fields, considered economically marginal.

This paper aimed to develop a model to estimate the generation of electrical energy through human muscular effort, using a generator bicycle, connected to the electrical grid. The motivation resulted from the author's experience in distributed electrical energy generation, which identified a difficulty in installing photovoltaic solar generation systems on the top of buildings. As a research methodology, this study used multiple linear regression using time, weight, height, and body mass index (BMI) as independent variables. The model showed promising results, presenting a high adjusted R-squared, respecting the assumptions associated with a linear regression model. The simulations based on the model showed a considerable energy generation potential for Brazil. In conclusion, although the estimated regression model presented a high predictive capability, further studies are recommended before any financial investment. © 2022, European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ).

Micro and Small Enterprises (MSEs) are a great source of social impacts and are more vulnerable to have worse social performance on their workers than bigger firms. Thus, it is important to aid decision-making to optimize the social impacts of MSEs on their workers. Hence, the purpose of this study is to apply a quantification framework to the qualitative results of a previous social life cycle assessment study applied in MSEs and to prove whether the quantification of the social impacts on their workers can aid to decision-making in this type of organizations. The method follows a four-step procedure and uses customized score factors for quantifying the social impacts on workers and was applied in three MSEs from three service activities. The results show several social hotspots that impacts negatively on MSEs' workers (Freedom of association, Fair salary, Working hours, and Social benefits), thus, some actions, such as the encouragement of association of workers to labor unions, the increasing of salaries, the reduction of working hours and the provision of more social benefits, are suggested to enhance the social impacts on MSEs' workers. So, the quantified results of social life cycle assessment allow to recognize social hotspots, they are a guidance to realize in what issues MSEs are impacting negatively on their workers and, thus, it aids to the decision-making, and encourages MSE-owners to take actions on it, in order to be more responsible with their workers and more socially sustainable.

In the last decade, evidence-based medical practice has been supported on a large scale by computerized decision support tools, aiming to reduce diagnostic and therapeutic uncertainty, complementing the actions of the health professional. With technological developments, it is now possible to consider these systems as part of clinical intervention, both for the diagnosis and treatment of diseases. The literature has described the implementation of e-health tools, that is, technological innovations in the health area such as software, applications, serious games, among others, as a strategy to improve the process and adherence to treatment. However, there is still no standardized instrument in Brazil that can be used to guide the development, from the research phase, and the implementation of these tools as a health intervention, also impacting patient outcomes. With the objective of investigating a new therapeutic and preventive form, based on intervention with a computerized system, this work proposes the creation of guidelines for the registration and implementation of e-health tools as a clinical intervention. The proposal aims to be able to assist in the reporting standardization from the development stage to the application of the e-health tool helping in the treatment of diseases, registering all the experience lived in the research and applying it in different contexts of health.

In its competitive form, CrossFit® intends on assessing the performance of athletes in a wide variety of aspects that determine their conditioning. CrossFit Games is an official competition and intends to recognize the best conditioned athlete in the world to each class. Thus, measuring an athlete’s Physical Conditioning is, in a sense, assigning a set of performance outputs that can determine the efficiency and efficacy of the athlete, discriminating the performance of one or more athletes. Since the scores obtained by the athletes in the various workouts are directly identifiable, the conditioning can be seen through the performance in a competition, it is, therefore, a result of the interpretation and scope of the workouts in measuring the performance. This work analyzed data form "CrossFit Open" and has as an objective to propose a new theoretical arrangement to the sport discipline while being of the Item Response Theory which is capable of providing data such as, discriminatory capacity and difficulty level of the workouts, as well as, an assessment of the competition. In other words, intends to describe the probability of an athlete performing a workout and obtaining a score, given his/her physical conditioning. Analysis of the main indications that refer to a good quality of the measurement tool indicates it is a high quality competition. Lastly, this work accomplished both objectives proposed, methodological as well as practical, and recognizes the limitations derived from the reduced amount of qualitative data on the topic and the little use of applied probability models. © 2022, CC BY.

Sustainable development is crucial for the competitive advantage of industries. However, implementing this business model faces challenges that can impact its integration and compromise the adoption of actions to address environmental, social, and governance (ESG) issues that are of interest to stakeholders. To date, no in-depth study has presented the relationship between ESG issues and practical actions employed for sustainable development in companies within the Latin American context. Therefore, this article aims to evaluate the relationships between the main ESG issues and the actions applied to develop this theme in the Latin American industrial context, highlighting the main barriers, opportunities, and implications for this integration. As a methodology, a documentary analysis of 79 reports from Brazil, Peru, Mexico, Chile, Colombia, and Argentina was conducted using the content analysis method. This analysis highlighted central concerns such as climate change, water management, waste management, biodiversity, local communities, diversity, and inclusion. Additionally, a trend of ESG thematic dissemination was identified, which is in an early stage of maturity and lacks studies to quantify and diagnose the environmental impacts of Latin American industries. These findings directly impact the empirical evidence of how the Latin American industry is neglecting social issues, is still developing studies to quantify its environmental impacts, and strongly adheres to the concept and theme of ESG. The conclusions of this study highlight three main points: (i) From 2018 to 2022, 47% of material topics were related to at least one ESG pillar, with a predominance of the environmental dimension, (ii) there was a trend of increased adherence to ESG and improvements in the materiality of reports, and (iii) it is recommended to enhance indicators, accelerate the sustainable transition, and integrate ESG themes into supplier selection and workplace safety to strengthen sus

Supplier evaluation is a core activity in supplier management and it is a key issue for organizations to retain and increase their competitiveness. Some critical factors must be considered to properly evaluate suppliers: the present uncertainty in decision makers’ (DMs) judgments and the judgments of multiple DMs from several functional areas. Hence, to achieve a choice that is accepted by the majority of the group, consensus reaching process (CRP) techniques are being studied in the literature. CRP techniques consist in an interactive process that is composed of multiple negotiation rounds, which enables the DMs to modify their judgments to reach the group consensus. However, this is very time consuming, which requires valuable resources from the organization. On the other hand, the use of machine learning techniques can eliminate the necessity of conducting multiple negotiation rounds during a CRP. Since no studies were found dealing with the pointed CRP problem, this study proposes a group decision making predictive model (GDMPM) based on ANFIS and on the Possibility Distribution-based Hesitant Fuzzy Linguistic Term Sets. Results show that the proposed GDMPM is capable to predict the results of a CRP only with DM’s initial judgments, without spending limited organization resources such as time and money. In addition, this study makes it possible for other purchase items to be assessed by multiple experts, and not only the most important ones. © 2023, The Authors. All rights reserved.

Urban in Indonesia, is no longer limited as a center of community settlement. Now the city also functions as a center of government, a central hierarchy, and a center of economic growth. As a logical consequence of the role of cities as a center of growth and economy, urban contributions to national economic growth are increasing. To overcome this problem, a portable conveyor of solar-energized drying system was designed. With the portable conveyor of solar-energized drying system, the dryer will be easily moved and flexible to use. The advantage of portable conveyor of solar-energized drying system is the drying process could be done continuously with a little human power. Therefore, this portable conveyor of solar-energized drying system is designed to use renewable energy sources. To examine the portable conveyor of solar-energized drying system, the foodstuff was used for a testing of ingredients. The portable conveyor of solar-energized drying system testing show that the amount of water content in the foodstuff reduced, the drying rate accelerate. In addition, the amount of heat energy needed for the drying process also reduced. Hence process of drying foodstuff more efficienct. © 2020 Published under licence by IOP Publishing Ltd.

The problem of sewage and waste disposal from U. S. Navy ships is recognized by the highest authorities in the Navy. Many activities and individuals are deeply involved in the total problem and its numerous subcategories. The problem of costs of disposal is one of these. This paper discusses four optional methods for the disposal of shipboard domestic wastes. The annualized investment and operating costs associated with the implementation of each of the options are presented. The model considers non-nuclear, sea-going surface ships with a manning level greater than 50 men. Estimates were developed on a per ship per class basis and aggregated for the total surface fleet. This approach permits the inevstigation of different combinations of the options by merely specifying the number and type of ships to be considered in any option. Changes in military effectiveness, which is at least an equally important problem as costing, were not addressed.
