Towards the Concept of Smart Municipality: Agribusiness Model Integrationg Rural and Urban Areas for Organic Food Production: A Review
Smart cities leverage information and communication technologies to enhance urban life quality, essential in densely populated environments requiring comprehensive planning. A critical area in urban settings is food production and delivery, where effective management becomes vital. New technologies can assist, but require models that support innovative production and commercialization methods. This study proposes an integration model between family farming—producers of organic food—and urban areas—consumers of these products. The model focuses on the management of organic food production and delivery to meet urban demands, serving as a tool in the transformation of these areas into smart municipalities. Additionally, this study suggests an alternative certification method for organic food production within family farming. A systematic literature review was conducted using the Methodi Ordinatio methodology. Content analysis of the selected articles identified strategies cities can adopt to promote organic certification, emphasizing transparent governance, public food procurement policies, and participatory certification systems. The proposed model aims to reduce bureaucracy and improve family farmers’ income, aligning with several Sustainable Development Goals: SDG 2 (Zero Hunger), SDG 8 (Decent Work and Economic Growth), SDG 11 (Sustainable Cities and Communities), SDG 12 (Responsible Consumption and Production), SDG 15 (Life on Land), and SDG 17 (Partnerships for the Goals).
Innovation Reefs (I-Reef): A New Concept For Innovation Ecosystems Focused On Regional Sustainable Development
The creation of successful innovation ecosystems, like Silicon Valley, is challenging due to significant cultural, infrastructural, and resource differences between regions. In this context, the Innovation Reef (I-Reef) model emerges as a promising alternative, offering an approach for regions with limited resources to develop successful innovation ecosystems based on cooperation and mutual benefit among participants. This model has great potential to promote regional development, especially due to its focus on retaining and sharing the value generated. However, the role of I-Reef in sustainable regional development still needs to be further explored. Thus, the objective of this study is to deepen the theoretical understanding of the I-Reef model by analyzing its contribution to sustainable development. To achieve this, a comparison was made between I-Reef and established models such as business, innovation, knowledge, and entrepreneurial ecosystems. A systematic literature review conducted on Scopus found 704 articles published in the last three decades. The purpose was to identify the similarities and differences between the models of innovation business ecosystem models. The results show that there is alignment between I-Reef and the different ecosystems on several points. A central aspect of I-Reef is that it relies on a strong network of mutually beneficial relationships, much more oriented to sustainable development than the other models, which is a key factor in generating competitive advantage and development for the region. This characteristic is either not addressed or not placed at the core of the ecosystems discussed in the literature. For future research, empirical studies and validation of the I-Reef model with experts are suggested, as this theoretical study lays the foundation for more in-depth analyses.
Integrating City Master Plans with Sustainable and Smart Urban Development: A Systematic Literature Review
Urban configurations have substantial impacts on lifestyles, behaviors, and people’s daily lives. Elaborating urban plans based on smart and sustainable initiatives is a challenging task as it encompasses numerous multidisciplinary premises due to the dynamics of the urban context. This research aims to conduct a systematic review of the literature in three axes: sustainable urban development, city master plans, and smart cities. From the portfolio of papers built, it was possible to map projects designed for sustainable urban development in order to verify the integration of these projects with city master plans, specifically for smart cities. The content analysis also sought to identify global regions that use robust models, their frameworks, and technologies for this purpose as a strategy to identify which research or frameworks can be replicated in the future, helping to develop city master plans for smart cities. Although some results were found, it was observed that there is a lack of studies integrating the topics of smart cities, sustainability, and city master plans in the same discussion. Few types of research involve the three themes or their full application, being mostly described in isolation. Thus, the originality of this study is filling this gap in the literature.

Measuring the Impact of Artificial Intelligence on the Higher Education Environment An Analysis of Learning at a Federal University in Brazil
Significant advances have been made evident in Artificial Intelligence in recent decades. Such advances are related to an evolution of several algorithms in machine learning, pattern recognition, natural language processing, automation, and robotics applications. Several software has started to integrate AI algorithms into their codes, covering a multitude of applications and providing countless solutions. These softwares can store large volumes of data. With advances in AI in recent months, specifically with the improvement of ChatGPT, new challenges have been imposed on teaching environments. Using various software, with emphasis on ChatGPT, the user began to interact with the machine in a more friendly way, allowing the AI to answer a multitude of questions. However, to what extent is there effective learning of the content proposed in a teaching plan given students’ easy access to AI tools such as ChatGPT? How will ethics in an evaluative environment deal with this issue? Therefore, this study intends to analyze and discuss the impacts of AI, specifically ChatGPT, in the classes of three Engineering courses at a federal university in Brazil. The big challenge is to measure student learning over an entire academic semester, after the massive emergence of ChatGPT, notably from November 2022. To achieve the objectives, a web page was developed to apply and evaluate the proposed scenario. In addition, two case studies were carried out: analyzing and measuring learning in a Computer Programming subject; and analyze and measure learning in two theoretical disciplines. 30 activities were carried out, distributed among the subjects of Programming Language, Computer Organization and Computer Organization and Architecture, totaling 902 responses in evaluation questionnaires. The results showed that, in Engineering courses with a strong technological bias, it is necessary to combine creative forms of teaching combined with AI, together with the content required in the teaching plans. Some students tend to carry out activities using ChatGPT to check their answers. The contributions of the work are to discuss how to combine new AI tools with teaching and at the same time be effective in learning. Therefore, it appears that new teaching strategies become necessary for the assimilation of content without AI tools causing a dependence on teaching and learning. It is necessary to discuss ethical issues of AI tools in education as these tools are gradually increasing.

inteligentes e economia circular.
Location as a key factor for waste to energy plants
The growing demand for energy, associated with the inherent challenges of urban solid waste management, makes many cities seek new treatment solutions, and among these, the Waste to Energy – WtE strategies stand out. However, the location of these plants still appears as a big challenge once it involves many factors in decision-making. In this way, the objective of this study is to identify the most relevant criteria for defining the ideal location for WtE plants and to point out the tools and methods most used in this process. To this end, a bibliographic review was carried out to find the main references on the subject. The results show that the place’s definition is complex and considers criteria of different natures – economic, social, legal, and environmental -. Among these, those of an economic nature are the most recurrent and, in general, deal with issues related to the costs of installation and operation of the WtE plant, like costs related to the transport of residues, availability of residues, and easy access to road infrastructure. In turn, although with less recurrence, the social, legal, and environmental criteria also show their importance in the decision-making process. Among these, the most recurrent were: social (distance to urban centers, acceptance by the population, and strengthening of the local economy), legal (land use), environmental (the minimum distance to water bodies, the topographical characteristics of the area, and the minimum distance to protected areas). Considering the tools and analysis techniques, the Geographic Information System – GIS and Analytic Hierarchy Process – AHP methods were the most used, appearing respectively in about 40% and 30% of the analyzed studies.

Girls, Music and Computer Science
In this Innovative Practice paper we describe our experience on using an updated methodology based on the paper “Music Education Meets Computer Science and Engineering” with a focus on pre-university female students. The main differences from this work are: (1) We taught the girls how to program and how to play the music instruments in parallel, having two classes per week, one for each subject instead of weekly meetings; (2) We started the project by using some of the games and puzzles from lightbot.com and code.org and then move to the Greenfoot Initial Learning Environment; (3) We asked the students to survey some music games related to their music instrument and design three potential games that they would like to develop using the music instruments; (4) They had to present and pitch the projects they designed to the undergraduate and graduate students of our computer music technology laboratory. Given the time constrains of the project, we had to help them to select the most feasible idea; (5) We applied a questionnaire to capture the perception of the students at the end of the project. It should be noted that all students successfully developed their music-based games using the digital music instruments and the Greenfoot Initial Learning Environment. In total four games were developed: (1) A game that allows drummers to perform ear training where they list to a particular drumming sequence and must replicate the sequence; (2) A game that allows guitar players to practice the execution of musical scales; (3) A game that allows keyboard players to practice their sight reading based on the simultaneous of two or more notes at the same time; (4) A game that allows bass players to practice their sight reading. It should be noted that by participating in the project one of the students acquired the skills and confidence to join the school and church bands.
Music education meets computer science and engineering education
This paper presents a novel interdisciplinary approach to aid with the growing concern about how to showcase computer science and engineering degrees to pre-university level students. This novel approach is based on empowering students to create their own music-related game using real music instruments. In order to allow the students to program their games we have used the Greenfoot Introductory Learning Environment to teach object-oriented programming skills with the java programming language. We have also taught the students music theory and practice. All these skills were required to allow the students to successfully develop their musical games that interact with the music instruments.
Latin Music Mood Classification Using Cifras
This article describes the automatic classification of emotions through five novel feature descriptors based on the “cifras” of the songs. A “cifra” is a document that contains the harmonic structure and harmonic progression a song. In order to evaluate the proposed feature sets, we have created a novel database, namely the Latin Music Cifras Mood Database (LMCMD). This database was created manually by the authors by querying different websites for the “cifras” of songs.
