Título: A IMPORTÂNCIA DOS CONTROLADORES DE DOMÍNIO EM AMBIENTES UNIVERSITÁRIOS: UMA ANÁLISE TÉCNICA E ESTRATÉGICA Autor(es): Moraes, Guilherme Henrique Cândido Abstract: The increasing complexity of information technology infrastructure in Brazilian public universities has demanded efficient solutions for managing users, devices, and network resources. In this context, the absence of centralized control can compromise the security, standardization, and governance of institutional systems. Given this scenario, this study aims to analyze the importance of domain controllers, with an emphasis on Active Directory (AD), in university environments. The methodology adopted was based on an exploratory and descriptive qualitative research approach, grounded in a literature review and documentary analysis of technical, academic, and regulatory sources. The study examined the functionalities, applications, and benefits of adopting a domain controller, highlighting aspects such as centralized authentication, enforcement of security policies, automation of administrative tasks, and improved resource management. The analysis showed that the use of domain controllers, when properly planned and maintained, significantly contributes to operational efficiency, the integrity of institutional data, and compliance with current regulations such as the Brazilian General Data Protection Law (LGPD). It is concluded that the adoption of this technology is strategic for higher education institutions, especially those with broad and distributed environments. The need for institutional IT policies that encourage the implementation and proper use of centralized management solutions is evident, aligning infrastructure, security, and quality of services provided.

Título: DESENVOLVIMENTO PROFISSIONAL: ITINERÁRIOS FORMATIVOS E PROFISSIONAIS DE LICENCIADOS EM CIÊNCIAS BIOLÓGICAS DE UM INSTITUTO FEDERAL DO INTERIOR DO BRASIL Autor(es): Costa, Jean; Ferreira, Gustavo Abstract: We used the principles of the biographical method to understand the professional and formative itineraries of graduates in Biological Sciences from IF Goiano Campus Ceres. To do so, we initially administered a questionnaire to learn about their itineraries and to identify those working in teaching. In this process, we sought to understand the potential contributions of the training institution to teacher professional development and/or the critical issues that still need to be addressed. The main results indicate that only 42.2% of the graduates work in teaching. Justifications for not working in the classroom mainly point to 'lack of motivation' and 'frustration with teaching and the system.' Among the respondents, 75.5% completed or are pursuing postgraduate studies. Of those working as teachers, 73.7% teach Science and Biology classes, and 21.1% teach other subjects, demonstrating a disparity between the formative itinerary and the professional teaching itinerary in basic education and the teaching situation in rural areas of the country. Finally, in teacher professional development, challenges include highlighting the integration between theory and practice in initial training, early exposure to the school reality, reflective practice in basic education, and enriching teaching experience through knowledge sharing and collaborative learning.

Título: MATHEMATICAL MODELING OF LACTOBACILLUS VIRIDESCENS GROWTH IN VACCUM PACKED SLICED HAM UNDER NON ISOTHERMAL CONDITIONS Autor(es): Silva, Nathália Buss da; Longhi, Daniel Angelo; Martins, Wiaslan Figueiredo; Aragão, Gláucia Maria Falcão de; Carciofi, Bruno Augusto Mattar Abstract: Lactic acid bacteria (LAB) are responsible for the spoilage of vacuum packed meat products, as ham. Temperature is the main factor affecting the microbial dynamics and its variation during the production, distribution and storage of foods is considerable. Thus, the use of mathematical models to describe the microbial behavior under variable temperatures can be very useful in predicting the food shelf life. This study evaluated the growth of Lactobacillus viridescens in sliced ham under non isothermal conditions, and assessed the predictive ability of the Baranyi and Roberts model using parameters obtained isothermally in culture medium (MRS). To obtain the BAL growth, the fresh ham piece was sterilized, sliced, inoculated with bacteria and stored in a temperature-controlled incubator. For the establishment of the secondary models, the primary model parameters were obtained isothermally in the culture medium at 4, 8, 12, 16, 20 and 30° C, in which there was no lag phase observed; the square root model was selected to describe the dependence of the μmax parameter (maximum specific growth rate) with the temperature, and the ymax parameter (maximum population) was represented by an average because there was no significant influence of the temperature. The mathematical models were validated with L. viridescens growth data in ham under five variable temperature conditions (NI-1 (4-8-12-16°C), NI-2 (12-16-20-25°C), NI-3 (25-20-16-12-8-4°C), NI-4 (16-12-8-4°C) and NI-5 (12-8-4-8-12°C)), and its predictive ability were assessed through statistical indexes (bias factor, accuracy factor and RMSE), with good results (bias factor between 0.9450 and 1.0326; accuracy factor between 1.0382 and 1.0682, and RMSE between 0.7641 and 1.3317), especially in increasing temperature, where the prediction was safe. The validated model can be used to estimate the shelf life of a commercial ham under different temperature conditions. Editor: Instituição extra IF Goiano Tipo: Artigo de Periódico

Título: ESTIMATION OF THE TEMPERATURE DEPENDENT GROWTH PARAMETERS OF LACTOBACILLUS VIRIDESCENS IN CULTURE MEDIUM WITH TWO-STEP MODELLING AND OPTIMAL EXPERIMENTAL DESIGN APPROACHES Autor(es): Longhi, Daniel Angelo; Martins, Wiaslan Figueiredo; Silva, Nathália Buss da; Carciofi, Bruno Augusto Mattar; Aragão, Gláucia Maria Falcão de; Laurindo, João Borges Abstract: In predictive microbiology, the model parameters has been estimated using the traditional two-step modeling approach (TS), in which primary models are fitted to the microbial growth data and secondary models represent the dependence of model parameters with environmental variables. The optimal experimental design approach (OED) has been used as an alternative to TS, mainly because the improvement of model identifiability and reduction of the experimental workload and costs. The fitting of mathematical model to experimental data in TS is sequential, whereas in OED is simultaneous. Lactobacillus viridescens is a lactic acid bacteria that is of great interest to the meat products preservation. The objective of this study was to estimate the growth parameters of L. viridescens in culture medium with TS and OED. For TS, the experimental data were obtained in six temperatures; for OED, the data were obtained in four optimal non-isothermal experiments, two experiments with increasing temperatures (ITOED) and two with decreasing temperatures (DTOED). The Baranyi and Roberts, and the Square Root models were used to describe the microbial growth, in which the b and Tmin parameters (± 95% confidence intervals) were estimated from the experimental data. The parameters obtained for TS were b = 0.0290 (±0.0020) h-0.5°C-1 and Tmin = -1.33 (±1.26) °C, with R2 = 0.991; for ITOED were b = 0.0314 (±0.0019) h-0.5°C-1 and Tmin = 0.12 (±0.71) °C, with R2 = 0.995; for DTOED were b = 0.0295 (±0.0019) h-0.5°C-1 and Tmin = -1.57 (±1.05) °C, with R2 = 0.999. The parameters obtained in the OED approach presented smaller confidence intervals, higher R2 and less experimental time than the parameters obtained in the traditional TS approach. In this way, it is possible to answer positively that OED approach is feasible and could be widely applied in predictive microbiology. Editor: Instituição extra IF Goiano Tipo: Artigo de Periódico
