Human-computer interaction tests applied to the +LEITE app for android
Get PDFThis article describes the application of two human-computer interaction tests (IHC) in an Android application© called "+Leite", created to help small milk producers measure the efficiency of their production. One of these tests is called Heuristic Assessment which consists of identifying errors based on the 10 Nielsen heuristics (1998) and classifying them into levels (mild, medium, severe and catastrophic), according to the severity of this error. The other test is called the Cognitive Pathway that consists of the evaluator impersonating the application user and plotting a path to be followed to identify usability problems. In these tests, aspects (positive and/or negative) of the software are raised and, with the possession of these data, it is estimated to improve the application
Profile of nursing professionals and factors associated with Covid-19 illness
Get PDFObjective: to identify the profile of nursing professionals and the factors associated with covid-19 illness. Method: Quantitative research conducted with 209 nursing professionals from a large hospital, between September and November 2020, through an electronic questionnaire. Descriptive analysis of the data was performed in the Stata version 13 program. To investigate differences between proportions (p<0.05) contingency tables with chi-square were used. Results: Among the professionals who get sick from COVID-19, the majority were female (86.44%), over 40 years of age (57.63%), married or in a stable union (55.93%), with religion (91.53%), nursing technicians and assistants (69.49%), with training time equal to or greater than 11 years (76.27%), working time at the institution of up to six years (81.36%), without another employment relationship (59.32%). Participants reported changes in sleep (59.32%), appetite (67.80%), leisure time (96.61%), physical activity pattern (94.92%), mood (81.36%), presence of anxiety (81.36%). Anxiety predominated among professionals of technical and higher level (p-value = 0.01) and illness due to COVID-19 was associated with the category of nursing technicians/assistants (p-value = 0.05). Conclusion: a greater vulnerability to COVID-19 illness was identified among professionals who provide direct care to patients affected by COVID-19
Study of Scientific Production on Production of Wooden Doors
Get PDFThe forest sector has a significant role for society reaching economic, social and environmental spheres. There is a range of products from reforestation, the most important are raw wood or logs, sawn wood, cellulose, wood panels, biomass and doors. The world door export market alone reached 3.84 billion dollars, considering an interval of ten years, it achieved an average growth of +3,3% per year. With the growing demand and the demand for quality from the external environment makes door manufacturers invest in innovation and studies on the subject. The present work used a bibliometric method in four databases (Scopus, ScienceDirect, Scielo and Mendeley) and articles and publications were searched in conference proceedings until 1996, with the theme of wooden door production, in order to understand what is being disseminated in the academic environment regarding this theme. Data were compiled on the year, authors, journals, countries and database that obtained the most publications. In general, we deduce the low explanation of this content, as few articles were found, the non-appearance of an author who stands out in this theme, in addition to the lack of publications between the years 1999 to 2010 and the lack of studies from China. which in turn is more exporter of this product
Aspects of design management in the context of technological innovation centers
Get PDFThe organizational structure of the Technological Innovation Centers (NITs) integrates diverse and complex management routines that, in general, impact on the capacity of Scientific and Technological Institutions (ICTs) to effect the transfer of technology. In this sense, the NITs seek means and tools capable of assisting in the operationalization of these administrative processes. Among the various possibilities, this article brings, in particular, the conceptual approach to design management. Design management establishes recommendations for the use of design resources according to institutional goals. Based on this approach, the article aims to identify management activities within the NITs and their relationship with design management. To this end, a literature review was carried out to build the theoretical framework, a documentary research to survey the innovation policy indicators (Ministério da Ciência, Tecnologia, Inovação e Comunicação [MCTI], 2019) and application of a likert-type questionnaire in consultation with five technological innovation environments in the region Northeast of Brazil. The study is classified as applied research with a qualitative approach with an exploratory and descriptive objective. The research showed that despite the understanding of the potential of design to promote technological innovation, design management is not a practice systematically integrated into the management processes of the NIT. Subsequently, it was possible to present a set of propositions for the application of design management that support the combination of the essential and complementary activities of the NIT for the transfer of technology
Ramachandran Chart: Validating Proteins Through a Three- Dimensional Structure.
No full textA few years ago, validating proteins to see if they were good or bad was a process that took years. With the creation of the Ramachandran Graph that evaluates protein structures through the angles φ (phi) and ψ (psi), this task became less onerous. With the evolution of computing and bioinformatics, platforms have been created to generate Ramachandran graphs in an online manner, however, the platforms have a high degree of usability complexity. The system proposed by this project puts the user as the center of the development, developing a system that can generate the Ramachandran graphs from the files sent, make the outlier analysis and return to the user through e-mail communication when the activities are finished
Podcasting as an Effective Pedagogy for Teaching Chemistry During the COVID-19 Pandemic and Beyond
Get PDFThe COVID-19 pandemic has forced all educational institutions worldwide to switch their active routine to ONLINE. With students attending classes virtually, a number of problems arose including the absence of social interaction and the imposed difficulty of digesting the materials of different courses, especially for those with a scientific background. General chemistry (GC), as an introductory course, is usually registered by students from different backgrounds, including Science, Engineering, and Agriculture. At the United Arab Emirates University, the second level of GC (GCII) is more focused on problem-solving as related to various topics. With the absence of face-to-face experience because of the COVID-19 circumstances, students’ understanding of the chemical concepts and implementing that in problem-solving has become a challenge. The current work investigates the effect of using professionally-made podcasts of GCII on the extent of understanding of students registered for this course during the period of 2020-2020 over a course of four semesters. The results of surveying the usage and feedback of students engaged in this experiment are outlined. Conclusively, this pedagogy is fully supported by most of the students who regard it as a suitable alternative to face-to-face settings
Early detection of weed in sugarcane using convolutional neural network
Get PDFWeed infestation is an essential factor in sugarcane productivity loss. The use of remote sensing data in conjunction with Artificial Intelligence (AI) techniques, can lead the cultivation of sugarcane to a new level in terms of weed control. For this purpose, an algorithm based on Convolutional Neural Networks (CNN) was developed to detect, quantify, and map weeds in sugarcane areas located in the state of Alagoas, Brazil. Images of the PlanetScope satellite were subdivided, separated, trained in different scenarios, classified and georeferenced, producing a map with weed information included. Scenario one of the CNN training and test presented overall accuracy (0,983), and it was used to produce the final mapping of forest areas, sugarcane, and weed infestation. The quantitative analysis of the area (ha) infested by weed indicated a high probability of a negative impact on sugarcane productivity. It is recommended that the adequacy of CNN’s algorithm for Remotely Piloted Aircraft (RPA) images be carried out, aiming at the differentiation between weed species, as well as its application in the detection in areas with different culture crop
Influence of Schools’ Management Financial Preparedness on the Implementation of Competence Based Curriculum in Public Primary Schools in Kirinyaga West Sub-county, Kirinyaga County, Kenya
No full textThe competency-based curriculum (CBC) is presently being implemented in public primary schools in Kenya. Yet, empirical evidence indicates that schools’ management faces a lot of challenges, hence making it very difficult for the implementation of the new programme. The study sought to explore the influence of schools’ management financial preparedness on implementation of CBC in Kirinyaga west subcounty, Kirinyaga County, Kenya. The study was anchored on Curriculum Implementation Theory, Theory of Organizational Readiness for Change, and Kurt Lewin Change Management Model. The study adopted mixed method approach, which allowed concurrent triangulation of data where both quantitative and qualitative methodologies were used. Target population comprised 68 headteachers, 1,020 teachers, 15, 500 CBC pupils and 4 sub-county education officials totaling to 16,592 respondents. Yamane Formula was used to sample 399 respondents that were identified using purposive and stratified random sampling techniques. A semi-structured questionnaire was used to collect quantitative data from teachers whereas an interview guide was used to collect qualitative data from head teachers and subcounty education official. Quantitative data was organized and processed descriptively and inferentially using SPSS (version 23) and presented using frequency tables. Linear regression was carried out under inferential statistics. Qualitative data was analyzed using thematic content analysis technique and presented using narratives. All research protocols were observed throughout the study, including obtaining all relevant authorizations and observing respect for the participants. The study established that schools’ financial preparedness has significant influence on the implementation of the CBC in public primary schools in Kenya. The study recommended that there is need for the government to provide enough financial resources for implementation of the CBC. School managers should be trained on how to mobilize financial resources to complement government efforts
Microentrepreneur, worker in Brazil and the challenges for health and quality of life
No full textIn the current scenario of transformations in the most diverse work activities due to the development and application of technologies, the flexibilization of labor relations, the high level of unemployment and economic uncertainties, there is a simultaneous growth in the number of individual micro-entrepreneurs in Brazil. The individual microentrepreneur personifies the precariousness of work in which health and, as a result, quality of life are compromised. This study analyzed the evolution of the number of micro-entrepreneurs in Brazil from 2010 to 2019 and its correlation with unemployment in the country. The data survey was carried out through the Entrepreneur Portal database and the discussion was based on the literature on worker health. The survey result indicated more than nine million micro-entrepreneurs in 2019. Exposure to precarious working conditions and weakening labor relations are determining factors in the health of workers
Technical and economic feasibility study for offshore transshipment operation: Case study for the port of Vila do Conde / PA
No full textIntercontinental cargo transport is carried out mainly through the waterway modal, increasing the number of vessels and the deadweight of ships. This means that onshore ports cannot stand the cargo demands and, to make them competitive in this reality, a very high investment is needed, and their expansion can produce serious environmental impact. Thus, it is necessary to search for alternatives that facilitate the flow of vessels in the regional and world scenario. Hence, the present work conducts a technical and economic feasibility study of a direct offshore transshipment operation of solid bulk cargo of vegetable origin at the Organized Port of Vila do Conde, in Brazil, using the Net Present Value (NPV) methods, Internal Rate of Return (IRR) and Payback. In the study, three scenarios were considered, each of which had its particularity related to the operating life and the amount of cargo handled. Therefore, it was noted that offshore transshipment is more viable in two scenarios – the project\u27s useful life is up to 14 years, so that the investment of capital in an onshore installation is more viable. Furthermore, it was found that, only in the worst-case scenario, offshore transshipment overlapped the other activity in any period of its useful life
