Quaestum 2020-10-05T17:18:58+00:00 Fernanda Latanze Mendes Rodrigues Open Journal Systems <p>Quaestum is a continuous flow publication linked to the PECEGE, located in Piracicaba, SP, Brazil. This journal is edited since 2015, replacing the Revista iPecege, and publishes scientific articles and bibliographic reviews (primarily by the invitation of the Editorial Committee) in the area of Applied Social Sciences, resulting from the development of research by national or foreign authors, with a rigorous double anonymous evaluation system.</p> Editorial Quaestum 2020-10-05T17:18:58+00:00 Humberto Francisco Silva Spolador 2020-07-14T00:00:00+00:00 Copyright (c) 2020 Quaestum Growth and instability of the 1992/93 - 2016/17 soybean crops in the main producing states of Brazil 2020-07-21T21:36:09+00:00 Osvaldo Chacarolli Júnior Priscila Fortes <p>The expansion of world demand for food and energy has<br />resulted in increased agricultural yields and production. Soybean<br />production, specifically, is among the economic activities that have<br />shown significant growth at national and global levels in recent decades.<br />In this context, policymakers and other agents involved in the soybean<br />production chain must pay careful attention to the instability with which<br />yield and production increases occur over time. Therefore, the objective of<br />this study was to evaluate this instability and growth in soybean planted<br />area, production, and yield in the main producing states of Brazil over<br />the 1992/93 to 2016/17 crops. We measured instability by applying the<br />Cuddy-Della Valle index and growth rates calculated using a log-linear<br />regression with post decomposition analysis. We observed that all<br />variables, in all states, presented a tendency of growth—particularly that<br />of planted area, which was the main production-defining element. We<br />additionally found low levels of instability for planted area, production,<br />and yield in most analyzed regions.</p> 2020-10-05T00:00:00+00:00 Copyright (c) 2020 Quaestum The benefits and challenges of a continuous improvement area in a manufacturing plant 2020-07-21T21:46:28+00:00 Carlos Vinicius Vasconcellos de Magalhaes Castro João Batista de Camargo Junior <p>A continuous improvement area is a department of a company<br>that seeks to support the implementation and execution of tasks focused<br>on the improvement of processes, which can add additional value<br>to production lines. As such, the goal of this paper was to identify the<br>benefits of a continuous improvement area to plant production and the<br>main challenges a rolled aluminum plant faces when implementing this<br>program at all levels of manufacturing. The methodology used to achieve<br>this goal was composed of qualitative interviews with 24 professionals<br>from the company under analysis—including mechanical technicians,<br>electrical technicians, and area leaders from the first, second, and third<br>tiers of the company—and a comparison of our data analysis with that of<br>the literature. The main results of this paper indicated that the benefits<br>of the plant’s continuous improvement area on production included the<br>reduction of waste, the training of the workforce, and the translation of<br>corporate goals into tangible goals for the plant. Meanwhile, we found<br>the main challenges faced by the continuous improvement area during<br>the application of this program to be an unwillingness of employees to<br>change the way they perform their jobs and the identification of the best<br>way to communicate with those involved in the program.</p> 2020-06-30T00:00:00+00:00 Copyright (c) 2020 Quaestum
