(2023-09-15) Silva, Kamilo Alaboodi da; Silva, Emanuel Araújo; Hakamada, Rodrigo Eiji; http://lattes.cnpq.br/4186459700983170; http://lattes.cnpq.br/2765651276275384; http://lattes.cnpq.br/5612600854790108
The forest inventory helps forest managers taking decisions. Installing, measuring and managing a network of inventory plots is a costly and time-consuming activity. The remote sensing techniques are increasingly gaining ground in the forestry sector because they have the potential to reduce costs without incurring any loss of precision, but they are not widely used due to their high cost. In this context, the Swedish company Katam Technologies has developed a solution for acquiring and analyzing forest data: KATAM Forest, which works using the KASLAM algorithm, which has not yet been widely used and tested in national forests. The goal of this study was to compare, in terms of accuracy and operational performance, the application of KASLAM artificial intelligence through the KATAM Forest application in forest inventory activities in Khaya senegalensis (Desr.) A. Juss plantations (5 years old), located in the state of Pernambuco, with the sampling techniques of a traditional forest inventory. Diameter at breast height (DBH) data was collected within 9 plots, as well as videos with artificial intelligence, recorded within the coordinates of the sampling units. Descriptive statistics were performed on the DBH data by plot, followed by the parametric Shapiro-Wilk normality test, where, if the null hypothesis was rejected, a non-parametric Mann-Whitney U test was required to understand the difference in averages. Operational performance was assessed using the time data obtained during the inventory process within the plots in both approaches. The DBH variable in the two inventory methodologies does not have a clear distribution concentrated close to the mean. The non-parametric test resulted in the averages obtained for DBH not showing statistical differences between the methodologies at the 5% significance level. The operational performance of the Katam methodology was half of the traditional inventory. The Katam technologies are very promising in terms of reducing time and costs in forest inventory operations. Therefore, further studies are recommended so that the subject can be disseminated in a practical way.

Study Astronomy is an interdisciplinary task, which involves several areas of science. During the stages of Basic Education, contact with this discipline can arouse interest in young people for professional careers related to Science and Technology. Despite its importance, the teaching of astronomy in schools is still deficient, either due to the lack of observation of the night sky as a practical activity or by the poor training of teachers. In front of the post, the creation of astronomy clubs collaborates with teaching-learning in the classroom, providing various activities that provoke critical-reflective thinking in the participants and help with the formation of citizenship. This article aims to create an application for mobile platform as an educational product that will be used by creators / managers of astronomy clubs. A checklist application will be created, where the club manager, even if a beginner in the task, has guidance and support for the application of activities, step by step, on the operation of an Astronomy club. The application was produced using the Massachusetts Institute of Technology's MIT App Inventor platform, a programming tool that programmers can build blockable applications without computer training required. It is expected that the application called "AstroGestor" developed will be available and free for all those interested in creating astronomy clubs in Brazil, being able to act as an electronic taskbook and easily accessible, which can help individuals in the procedures of astronomy club activities.

(2019) Santos, Edja Sabrina Sá; Cabral, Ana Maria Duarte; http://lattes.cnpq.br/9120227816308243; http://lattes.cnpq.br/9115496783033924
The breeding of goats and sheep is a very old practice in Brazil, mainly in the Northeast, making it possible to generate income for the producer through the sale of meat, viscera, manure, skin, milk and dairy products. A major difficulty encountered by ranchers is the irregular distribution of rain during the year and the greater prevalence of animals with no defined breed pattern, causing the supply of low quality products and by-products in the market. Despite this situation, the creation of small ruminants in the semi-arid region becomes a socioeconomically viable alternative, since this practice has a strong expression for producers. The research was carried out from December 2018 to February 2019, with the possibility of interviewing the owners or managers of 65 establishments, of which 30 supermarkets, 16 establishments within the public market, 1 poultry house, 1 wholesale, 5 butchers, 3 agricultural stores, 5 bakeries, 1 salgadeira and 3 autonomous owners. Information on the marketing of products and by-products, frequency of receipt, quantity purchased by the trader and the type of slaughter used on those animals could be obtained. Among the establishments identified in the city, 85% were considered and 15% could not answer the questionnaires. Of the Establishments with potential for marketing meat, 21.73% sold goat meat, while 17.39% sheep meat. Regarding the marketing of viscera, the city's butchers represent 50% of the total marketing of viscera. In the case of the commercialization of milk and milk products in the city, it was possible to observe that in the city this type of product presents a low expression. As far as fur trading is concerned, its identification was possible in only one point of the city. Regarding the commercialization of manure, it can be seen that it has a low Expression in the agricultural and livestock stores, and it is possible to identify only the sale made by autonomous owners who seek and resell the product. With this, it is possible to infer that the trade of goats and sheep in Petrolândia - PE is marked by a low commercialization of these products and byproducts in formal places, such as supermarkets and agricultural stores, being more common to find these products and byproducts in butchers and public market.

The presence of Digital Information and Communication Technologies (DIT) in education has grown significantly over the years. This growth can be seen mainly in the frequent use of smartphones and tablets in the classroom, and in the number of applications (apps) for educational purposes available on digital platforms. For the teaching and learning of Chemistry, and specifically the subarea of organic chemistry, the contributions that help the understanding of this Science are unlimited, based on the visualization and interaction provided by the available applications. However, for a conscious and objective use of this tool, it is necessary that the teacher knows how to administer it in a structured way to achieve positive results in the students' learning process. Thus, the present work aims to develop a new model based on technical and pedagogical aspects, existing in evaluation models of Digital Educational Games (DEG) incorporating Bloom's Taxonomy, in addition to analyzing Organic Chemistry applications (Apps). available for free on the Google Play® platform. To achieve this, the methodological path consists of 4 steps: 1) Survey of organic chemistry applications available on Google Play® through the latent corpus; 2) Survey of models and evaluation instruments for educational digital games on the Google Scholar platform; 3) Development of a model for evaluating apps; 4) Analysis of chemistry applications found in the latent corpus, according to the model for evaluating the proposed applications. The results show that there is a diversity of organic chemistry applications, as well as JED assessment models, contributing to the development of the Educational Application Assessment Model (EAAM), composed of categories and requirements that make up technical and pedagogical aspects found and adapted from the DEG models analyzed. Furthermore, based on the EAAM produced, we analyzed Organic Chemistry applications, identifying characteristics that can be used in teaching chemistry, including: quiz characteristics, good technical functioning, levels of complexity in the content, among others. Finally, research indicates that EAAM has the potential to assist teachers in choosing applications available in application stores, given its focus on technical and pedagogical aspects that influence student learning, in addition to being able to be used for the construction of new applications in different areas, in addition to Chemistry teaching.

The objective of the present study was to characterize the trade of goats and sheep products in the municipality of Pesqueira - PE with the use of mobile applications. The research was conducted through interviews with owners of commercial establishments in the municipality of Pesqueira-PE, carried out between January and February 2019, with the help of the application Zooquestions, which contains questionnaires related to the marketing of products and byproducts from small ruminants. The collected data were transferred to an Excel spreadsheet, were organized by means of mathematical and comparative constructions, in order to obtain the results. It was observed that only six districts of the municipality presented commercialization of products and by-products of goats and sheep. Among the products, milk, cheese, curd, meat, skin and viscera were found, most of them were informal commercialization, without complying with current legislation, where 93,75% of the slaughter was clandestine and 100% of meat were stored in an "in natura" way. The skins were marketed by producers and traders, the skin being clean, clean and salty without the criteria for purchase. Of the milk, 100% was commercialized in an "in natura" way, also emphasizing informal commerce. The cheese and curd sold were handmade, made from products and by-products mostly in the backyards of the producers' houses. In this context, it can be seen that the trade in goats and sheep products is significant and well distributed in the municipality of Pesqueira-PE, but has not yet reached the level of potentiality it presents, mainly due to informality.

It is as a result of the development of Digital Information and Communication Technologies (DICT) that today, in the 21st century, several paths can be created in order to enable the construction of knowledge in an educational context. The means by which teaching and learning processes are applied, formerly limited to four walls in traditional and authoritarian teaching, have been acquiring more space in the digital world and this reflects the idea of having a future even more immersed in this scenario. Smartphone apps, for example, are already a reality in education and both teachers and students have been making progress in their use inside and outside the classroom, enabling mobile learning, a very relevant feature in the digital age. That said, this work aimed to develop an app in augmented reality for teaching the concepts of Chemical Kinetics in order to assist, as a digital didactic resource, in educational processes. For its development, paths were sought for a basic training in the area of programming in order to broaden the vision and know which is the best software for app development in augmented reality (AR). The software chosen for the action were Unity and Vuforia, since both allow mutually creating and associating their resources such as graphic assets, markers to be plotted using their coordinates, in addition to operations such as animation, AR association and finally creating apps. Initial tests were carried out by the software used in the work, culminating in the production of two AR experiments using graphical objects from the Unity library, serving as a starting point for building the app as a whole. The proposal for the development of the app in Augmented Reality proved to be quite interesting with regard to innovation for teaching Chemistry, such as the product acquired in this process, having the potential to work in the classroom by both teachers and students.

Science and technology are essential for the socioeconomic development of a society, and for understanding the complexity of the world through scientific education to citizens so that they recognize science as an integral part of their culture. In this context, the internet and its digital platforms work as enhancers for the accessibility of scientific and technological information. Currently, a lot of information about the medicinal use of Cannabis sativa L. is being published in the most diverse media, but this information does not always have a scientific basis. Most of society is uninformed of the implications of this plant in the treatment of various pathologies, especially in the treatment of neurodegenerative diseases. The objective of this work was to create a mobile app, the Endocannabinoid, with scientific information, adopting communication strategies in simple and accessible language. The FabApp website was used to create the application, academic research platforms, such as Google, Scielo and NCBI, to reference and Canva to create teaching materials, such as images, visual content and logo. Thus, the development of this application made it possible to scientifically inform people about the medicinal use of Cannabis sativa L., and the Laws governing the cultivation and medicinal use of the plant, and it has contributed to improving the quality of life of people suffering from diseases which can be treated with the active principle of this plant.
Desenvolvimento e utilização de aplicativos para ensino de astroquímica
(2022-06-09) Silva, José Ewerton da; Henrique, Mariana Alves; Leite, Bruno Silva; http://lattes.cnpq.br/4932752031807872; http://lattes.cnpq.br/3375067276397113; http://lattes.cnpq.br/6546177378625414
Understanding the Universe that surrounds us is a great challenge and it is through education that we can interact with this reality. Awakening the interest of students in Sciences such as Astrochemistry has been a challenge and the lack of knowledge in this area has brought consequences for our society, because it is through Astrochemistry that we have knowledge that space is full of molecules and that many molecules of planet Earth were formed in space. Astrochemistry is a multidisciplinary science that studies atoms, molecules and chemical reactions in outer space, as well as understanding the evolution and chemical composition of the universe, the chemical phenomena that take place in space. In view of these difficulties, the present work aims to develop a didactic strategy for using an application in the teaching and learning process of Astrochemistry. Currently, the use of digital technologies (DT) is becoming increasingly popular and many people have access to smartphones and the internet, making this resource even more accessible for educational purposes in the teaching-learning process. The developed application, called AstroQuímica, was created with the help of the “app factories” platform known as Fabapp. AstroQuímica is an application of chemical knowledge related to Astronomy that aims to provide content and curiosities about the Chemistry of the universe. In the application, in addition to contributing to the study of this Science, it makes it possible to check your knowledge with questions about Astrochemistry. In order to obtain a more effective result in solving problems faced by basic education teachers, a didactic sequence (SD) was developed as a proposal for using the application.

(2017-09-06) Silva, Diógenes José Carvalho da; Lins, Fernando Antonio Aires; http://lattes.cnpq.br/2475965771605110; http://lattes.cnpq.br/0986435158192139
The mobile applications platform known as Android provides a wide an open environment of application development to all kinds of software, however this freedom can bring possible software security vulnerabilities that can be used unfortunately to create threats to the operation system. There are vulnerabilities that comes from software and hardware that allows the creation of threats called: spyware, diverse kinds of malware, and with raising popularity, the ransomware. In this case is necessary to build application analysis to find out threats that are increasing in size and complexity. To accomplish this task, this research proposes a technique that combines multiple strategies to orchestrate a new technique that can detect threats and vulnerabilities inside applications developed to the Android mobile operational system. The strategy combines automatic static analysis and threat profile identification by metadata from an external source. Using techniques like web crawling to collect metadata from application stores, we generated a data set with 1000 applications, which 500 are infected and 500 aren't, using balancing technique such as super sampling, extraction and selection of features like: TF-IDF, frequency of terms, feature conversion from nominal to binary and normalization. Using the generated data set to create classification models with the most used machine learning algorithms used by other researchers, we could provide precision metrics, false positives, and false negatives at acceptable rates, comparable to other researches that presents the same performance metrics.

Environmental education corresponds to an educational process related to socio- environmental issues, which by law must be addressed in schools at all levels of education. Also considering the importance of this theme with regard to the construction of sustainable actions related to daily socio-environmental practices, which are urgently needed to be thought out and developed in schools. Based on this, this work aims to analyze the contributions of digital resources, such as apps, in the teaching-learning process focused on environmental education at school. From an intervention project that took place in the seventh year of elementary school, the positive impact of using this resource was evident, since it promoted interaction and instigated students' critical sense regarding the importance of this theme and the extent of the socio-environmental impacts caused. of an anthropic order. We therefore consider the use of technologies in environmental education as a positive resource in the teaching-learning process of students, as it stimulates and makes the class attractive, contributing to their active participation and effectively with their learning.

A tecnologia LiDAR tem avançado significativamente, permitindo a obtenção de dados tridimensionais detalhados sobre a estrutura das florestas, sendo amplamente utilizada na engenharia florestal para inventário, planejamento de manejo e modelagem de crescimento de árvores; aplicativos que incorporam LiDAR, como ForestScanner e Arboreal Tree, têm mostrado potencial em fornecer estimativas precisas de variáveis dendrométricas. O estudo foi realizado na Estação Experimental de Cana-de-açúcar do Carpina, em Pernambuco, onde dados de diâmetro e altura foram coletados manualmente e por meio dos aplicativos ForestScanner e Arboreal Tree, utilizando o sensor LiDAR do iPhone 13 Pro, e as medições foram comparadas para avaliar a precisão dos dados obtidos pelos aplicativos em relação aos métodos convencionais. Os resultados mostraram uma forte correlação entre as medições convencionais e as obtidas pelos aplicativos, com o ForestScanner apresentando um coeficiente de determinação (R²) de 0,852 e um RMSE de 2,24 cm para o diâmetro, enquanto o Arboreal Tree mostrou um R² de 0,9501 e um RMSE de 1,44 cm; para a altura, o Arboreal Tree apresentou um R² de 0,7857 e um RMSE de 1,31 m, indicando que ambos os aplicativos fornecem estimativas precisas e podem ser usados como alternativas eficientes aos métodos convencionais de medição. A utilização do sensor LiDAR no iPhone 13 Pro, combinada com os aplicativos ForestScanner e Arboreal Tree, mostrou-se eficaz na estimativa de variáveis dendrométricas, destacando a importância da tecnologia LiDAR em dispositivos móveis como uma ferramenta inovadora e prática para a coleta de dados florestais, oferecendo precisão, economia de tempo e custos na obtenção de informações sobre a estrutura florestal.
