Cold rooms are fundamental equipment for the preservation of perishable foods, guaranteeing the maintenance of the quality of products in the stages of their processing and distribution. The correct dimensioning of this equipment represents efficiency related to the cooling and freezing performance, as well as the energy efficiency of the system. This project deals with the development of a computational code on the EES platform (Engineering Equation Solver) to determine the energy consumption of the evaporator unit (thermal load) of a cold room. The study presents parameterized results for the thickness of the thermal insulation and the inlet temperature of the products. It was verified that the discrepancy between the maximum and minimum operation regimes of the cold room, represents a reduction of approximately 20,19% of the energy consumption of the evaporator unit. Thus, it can be concluded that the parameterized study can result in a diagnosis of energy savings for cold storage projects.

Introduction: The occurrence of deaths due to drug intoxication has been considered one of the public health         problems. Objective: To describe the main determinants of drug poisoning in the city of Teresina-PI. Methodology: Ecological, descriptive, quantitative and population-based research, with a study of poisoning by drugs reported in the city of Teresina-PI, from 2010 to 2019 by the Ministry of Health/SINAN. The following data were collected: gender, ethnicity, education, age group, clinical evolution, final classification, circumstance, confirmation criteria and the municipality of residence in Piauí. 2019. Results and discussion: In the period analyzed, 2,229 occurrences were recorded, with the predominant ethnicity (41.36%), education with complete high school (12.43%), age group 20-39 (43.43%) and female (73.44%). As for the type of exposure to acute-chronic, it occurred in 1287 records (57.74%), and the criterion for confirmation was clinical (64.56%). The most frequent circumstance was attempted suicide (71.02%) and the final clinical outcome was cure with no damage (59.22%). Conclusion: It was found that in the city of Teresina-PI there was an increase in notifications, this fact can be attributed to the pattern of drug consumption. In general, Health Surveillance must prioritize professional sensitivity to obtain more educational, preventive and intersectoral actions to ensure the improvement of health surveillance policies.

The aim of this study was to verify, through a systematic review, whether the active methodology of PBL (Problem Based Learning) is applicable for teaching the discipline of Dental Radiology. This review was carried out following the guidelines of PRISMA-P, using the PICO strategy to implement the eligibility criteria, seeking to answer the following question: “The PBL (Problem Based Learning) is applicable for the discipline of Dental Radiology?”. A systematic review was carried out in the PubMed databases (including MedLine), SciELO, LILACS, Web of Science and IEEE Xplore, as well as a search in gray literature in the electronic platforms, OpenThesis and Open Access Thesis and Dissertations, in addition to the manual search for cross-references of original articles. In addition, the Bollean operators, AND and OR were used, combined with the descriptors, these selected using the Descriptors in Health Science (DeCS) and Medical Subject Headings (MeSH), to enhance the search strategy. The selection of studies was performed by two reviewers and eligibility criteria were adopted for the selected works. The PBL proved to be a teaching methodology that brings benefits for the training of dental surgeons capable of dealing with daily situations, being a viable and applicable alternative for the discipline of dental radiology. However, due to the uncertainties found in the studies those included, evidenced by the high risk of bias, further research should be carried out to reduce such knowledge gaps about the best method in the teaching-learning process.

Popcorn consumption is increasing progressively worldwide. Landrace popcorn (LP) are cultivated in family farming. The objective of this study was to characterize a LP in an organic system by family farmers. LP was analysed for the phenotypic characterization and race identification, germination and vigor, thickness/width ratio, circularity index, sphericity, diameter ratio, geometric mean diameter, volume, surface area, angle of repose (AR), hectoliter weight (HW), apparent specific gravity (ASG), thousand kernel weight (TKW), color, and classification according to identity and quality requirements. LP is of an indigenous Guarani origin and belongs to the Avatí Pichingá Ihú race. The variety yields a high germination and vigor and can be used as seeds. The dimensions and calculated indices had important variations among the grains, demonstrating a wide genetic diversity, typical of landraces. The low AR, associated with the dimensions, revealed the small size of the LP grains. Higher values for HW, ASG, and TKW indicated higher levels of vitreous endosperm, hardness, and starch content. The coordinates a * and b * respectively indicate the red and yellow colors while the low value for the parameter L * indicates the intense color of the LP. Corn was classified as type 1 according to the percentage of physical defects, however, the expansion capacity presented a value below the reference for commercialization. The potential of the studied variety is verified to be used by industries, mainly the food sector. Its cultivation can be stimulated by family farming, ultimately impacting grain production and promoting the rescue of germplasm.

Objectives: understand the daily lives of nursing managers regarding violence in the work environment; relate managerial strategies with disruptive behaviors in the nursing team. Method: this is a descriptive-exploratory research with a qualitative approach. Five managers from the Nursing area were interviewed by means of recorded interviews with guiding questions. Results: from the speeches, three categories emerged: "Articulate actions in the face of power relations"; "Dialog and welcome when faced with adverse situations"; "Importance of support from top management". Conclusion: the analysis of the speeches allowed us to understand the experience of nursing managers in their different work environments in relation to situations that involve risks to workers' health and the quality and safety of the care provided.

Not all business in the market get customer attentions as they deserve, especially for Small Medium Enterprise (SME). It sparks fierce competition between SME to stand out from rivals in the market. Sales promotion is known as one of the most effective method which influence sales volume, especially for SME’s market. The second strategy is having endorsement from a third-party. Previous studies have identified impact of monetary promotion through online and in-store strategy to build strong brand identity without, and so as endorsement. However, there is still inadequate understanding of branding development particularly what specific promotions and endorsement works better for SME, as previous research are mostly based on multinational or big firms which have different characteristics with SME. Therefore, this paper examine the impact of two types of promotions, which are: monetary (vs non-monetary) promotion and celebrity (vs.non-celebrity) endoresement into better customer perceptions about SMEs’ product and brand.

An initial study on maize lines is essential to obtain hybrids. In the selection of strains, several parameters are observed to reach the crossing and commercialization. Some authors state that adequate nitrogen fertilization is needed to increase the corn economic productivity, considering N is the most required macronutrient by the crop. This nutrient performs diverse metabolic functions in seeds, contributing to their formation and nutritional reserve. Therefore, this paper aimed to evaluate the production and quality of irrigated corn lineage seeds under nitrogen doses and moisture levels at harvest time. The experiment was carried in the experimental area of the Goiano Federal Institute, Ceres Campus, Goiás State (GO), Brazil, and in its SAL. The experimental design was in randomized block, split plots, twenty treatments with five nitrogen rates (50, 110, 170, 230, and 290 Kg ha-1), and harvest took place with four moisture degrees (15%, 25%, 35%, and 45%). A maize line the PGAG10051L. Field and laboratory tests were carried out. The studied strain tolerates low nitrogen availability and has high efficiency in its use. The strain responds positively to the nitrogen increase in relation to germination percentage with better results above 170 Kg of N ha-1. The strain has high capacity to accumulate biomass in caryopsis even with low moisture content. Seeds harvested with 25% moisture showed satisfactory results for germination and vigor. It is recommended to apply 170 Kg de N ha-1 nitrogen dose split in four times for topdressing the corn lineage studied in this paper.

This study aims at developing and validating a scale for measuring overconfidence and optimism in the context of business decisions, with an emphasis on instrument validity. Although overconfidence and optimism are two of the most researched biases in the field of Behavioral Finance, the limits, and intersections between them lack clarity in the available literature and research. The optimism and overconfidence bias items emerged as provisional responses to the following question: In what situations do the optimism and overconfidence biases manifest themselves in the decision making of managers? Exploratory and confirmatory factor analyses were used to create a 13-item scale to measure these biases in the behavior of decision makers. The results of the factor analyses have generated a two-factor structure. The model for measuring the biases of optimism and overconfidence in investment decisions demonstrated a good fit of the model, adequate reliability, convergent validity, and discriminant validity. Optimism obtained the highest average score, followed by overconfidence. The present study resulted in a research instrument capable of identifying the influence of overconfidence and optimism biases in managers' decision making in organizations. The questionnaire can be used in other empirical studies on behavioral finance, business decision making, and investment decisions.

Recently, the use of type I collagen obtained from Nile Tilapia (Oreochromis niloticus) was proposed for the treatment of second and third-degree burning lesions and diabetic ulcers due to its occlusive and healing properties. The aim of this report is to describe the use of Nile tilapia skin as an occlusive barrier to protect palatal wounds after the removal of free autogenous soft tissue grafts. Two patients with a deficiency in the height of keratinized mucosa were indicated for treatment with free gingival grafts. The palatal donor area was covered with a Nile tilapia skin, stabilized by sutures. Seven days after surgery, patients returned for post-operative care. Patients’ reported outcomes were investigated by the use of a visual analogue scale and included pain, discomfort, impact on chewing and speaking. Analgesics consumption was also recorded. Standardized photographs were obtained to monitor wound healing. Patients were followed up for 30 days. Patients reported reduced pain levels, with low consumption of analgesics during the first week after surgery. No discomfort or difficulty in chewing or speaking was reported. No complications such as hemorrhage or edema were observed. These findings suggest that the Nile Tilapia skin may be an interesting alternative as an occlusive biological dressing in palatal wounds harvest of free gingival grafts.

Childhood sleep-related problems can predict later emotional and behavioral disturbances, such as anxiety. Thus, this study aimed to investigate the relationship between sleepiness and anxiety symptoms throughout the semester in schoolchildren aged 9 to 11 years old. Children enrolled in a public school, located in Vitória de Santo Antão, Pernambuco, Brazil, of both genders, without sleep disorders, physical disabilities or cognitive disorders (n = 88) were evaluated. The State-Trait Anxiety Inventory was used to analyze mood. Subjective sleep assessment was performed using the Epworth Sleepiness Scale and the Horne & Ostberg Morningness and Eveningness Questionnaire (MEQ-HO). The questionnaires were applied in the morning at the beginning (P1) and at the end (P2) of the school semester, with the exception of the MEQ-HO. The correlation between sleepiness and state of anxiety in period 1 (r=0.16; p=0.21) was insufficient, as well as in period 2 (r=0.34; p=0.01). There was a low correlation between sleepiness and anxiety traits in period 1, while the correlation was moderate in period 2 (r=0.48; p<0.001). The correlation between sleepiness and the trait and state of anxiety presented a low to moderate correlation in the positive and negative aspects of anxiety. The data reveal that the evaluated students present abnormal daytime sleepiness at the end of the school semester and such alterations can worsen the anxiety trait in the evaluated children.

This review aims to present evidence as to the relevance of pharmacotherapeutic monitoring provided to patients with type 2 diabetes mellitus treated in community pharmacies, in addition to knowing the role of community pharmacists in the control of type 2 diabetes and investigating the positive aspects of pharmacotherapeutic monitoring aimed at diabetic patients. This is a literature review carried out by searching for original articles in databases such as Scielo, PubMed and Lilacs. The inclusion criteria were: publications that met the proposal of the theme, complete articles, in portuguese and published from 2010 to 2019. The exclusion criteria were: incomplete studies, which did not meet the objective and theme of the research, in addition to books, dissertations and theses. The articles that made up the review showed that the main doubts of patients with DM were related to the times of administration of the medications. Other findings showed that there was good acceptability of the proposal for pharmacotherapeutic follow-up and that its applicability in private community pharmacies brings several benefits such as greater adherence to treatment, occurring rationally with improved clinical results and establishing a link between pharmacist and user, reaffirming the capacity pharmacist to carry out clinical activities in the private sector. This study made it clear that the practice of pharmaceutical care and good dispensing practices aimed at patients treated in drugstores can be achieved without the need for major structural changes in the establishment and without hiring additional staff.

Introduction: Exogenous intoxication (EI) is the second most commonly used method to commit suicide, preceded by hanging, and is the first in terms of suicide attempts. Objective: To analyze suicide attempts to EI prevalence and the factors associated with this practice in the population of of the municipality of Birigui/SP. Methods: This is a descriptive, retrospective and observational study of the population of the municipality of Birigui. Data obtained by extracting information contained in the database of the Department of Informatics of the Unified Health System (DATASUS ) of the Brazilian Ministry of Health. Using the TabNet Win32 3.0 program, we analyzed data for the period 2013 – 2017, focusing on six variables: race, sex, education, age group, clinical evolution, and type of exposure. Results and conclusions: 296 cases were studied, increase in suicide attempts by EI through medication over the years from 27 cases 2014, culminating in 108 cases in 2017. Most cases were with females in all years (n=35 in 2013, n =27 in 2014, n=35 in 2015, n=51 in 2016 and n=84 in 2017), The highest incidence was found in the 15–19 years population (n = 49) with low education. Acute, single exposure intoxication predominated over others with 53% of cases (n=157) and cure without sequelae was observed in 63.9% of cases (n=189). During this period, there was an increase in suicide attempts due to EI over the years predominantly young women and persons of a low level of education.

The crisis caused by Sars-CoV-2, which causes Covid-19, is an ecological crisis. The agency of effective actions for its control and overcoming requires a systemic understanding of the phenomenon and the concept of syndemic is more appropriate as it encompasses such complexity. Thus, we discuss the rupture of sociometabolism between human being/nature in the midst of alienated relations of production carried out in the market and how the movement of ecovillages contributes to reconfigure the human being/nature relationship based on ecological bases. The agricultural and construction industries, which model the spatial distribution in the countryside and in the city based on the logic of capital accumulation, exert strong pressure on ecosystems and are taken as a reference in this investigation. The experiences of four ecovillages, through ethnographic-inspired research, reveal an organizational type that, once oriented towards self-sufficiency mediated by self-managed communal work, has the potential to reconfigure the human/nature relationship, mitigating the embarrassments of the market enclave and the consequences of the syndemic via polyculture practices, bio-constructions and dissemination of their ideals for their militancy and ecological education, while touching on the fundamental points of the crisis, that is, socio-environmental degradation.

The ways of thinking about global sustainability have generated important discussions in the last decades. Transformations linked to modes of consumption and human identities and subjectivities stood out in the context of discussions involving responsible consumption. These movements have changed the ways of production, consumption and the marketing of products. Based on this, this paper presents a reflection resulting from the desire to understand the effects from the articulation between proposals for environmental awareness, the principles of sustainable development, green marketing strategies and discussions on the ways in which cultural values ​​are established through of educational movements, in Brazil and in the world. The discussion is relevant to critically think about the ways that marketing interferes with culture and the notion of sustainability. This action was developed through qualitative research, based on a literature review. Based on this, it is understood that green marketing strategies educate for consumption based on the establishment of a given culture of sustainability.

Introduction: Information on potential drug interactions (PDI) are obtained from databases available on the web or through mobile healthcare applications (mHealth), and can prevent unfavorable clinical outcomes for patients. This study compared PDI information available in Micromedex® drug interaction checker, its web version and its mHealth app. Method: A cross-sectional study realized based on a retrospective review of drug prescriptions in a reference hospital in infectology in the Midwest Region of Brazil, 2018. We selected all prescriptions containing two or more drugs. Drugs were classified according to the first level of the Anatomical Therapeutic Chemical (ATC) classification, according to the route of administration and the number of drugs prescribed. PDIs were classified according to the severity system and four-level evidence classification system. Results: This study selected 72 patients, predominantly male, median age of 38 years, average length of stay of 15.8 days, and most diagnosed with HIV/AIDS. The most frequently prescribed anatomical groups according to ATC were digestive system and metabolism (22.1%) and general anti-infectives for systemic use (21.6%). The average number of drugs per prescription was 10.8 (SD±6.7). The Micromedex® mHealth app found 381 PDIs while its web version detected 502 PDIs, with an average of 5.3 and 7.0 and frequency of 61.1% and 72.2%, respectively. According to the severity classification in mHealth and web versions, the following stood out, respectively: 221 and 321 severe; 139 and 149 moderate. The majority (>65%) of identified PDIs had their documentation classified as reasonable. Conclusion: Digital tools although they aid decision-making, are not unanimous and consistent in detecting such interactions.

The internet enables the search for several subject types, including health and drug utilization. These information are spread generally without reliability and scientific basis, that can encourage self-medication and indiscriminate medicine use. This was a cross-sectional study, carried out through application of tools that evaluated the quality of global health information and the specific content about analgesic drugs on 98 Brazilian websites. Among the most cited drugs on websites, nonsteroidal anti-inflammatory drugs (83.67 %), acetaminophen (47.96 %) and opioids (47.96 %) stood out. All websites described pharmacological treatment options for pain, however, most websites did not mention any adverse reactions or contraindications for painkillers use. Information on opioid addiction and tolerance risk was present only in 18.37 % of websites. Considering all the indicators evaluated, no website was considered to be of good quality, even those with a quality certification seal. These results showed important shortcomings on health and drugs information published on internet, which can lead to analgesics inappropriate use, adverse effects and even intoxications events. This reinforces the need to control this information and to adopt minimum quality criteria for the websites, aiming to minimize health risks, drug irrational use and to contribute for lay public’s safety.

The objective of this work was to carry out a systematic review of the scientific production on the use of species distribution modeling for forest restoration. Searches for scientific articles in the Scopus and Web of Science databases for the last 15 years were performed in December 2020 using the terms: "ecological modeling" OR "biodiversity modeling" OR "predictive models" OR "modeling of niche" OR "habitat models" AND "species distribution" OR "geographic distribution" OR "potential distribution" AND "forest restoration" OR "restoration ecology". For the statistical and graphical analysis of the raw data the Bibliometrix package was used of the R software. The raw data were refined by selecting the studies that meet the following criteria: (i) studies published in scientific journals with an impact factor equal to or greater than 2.0; (ii) studies in which the title or abstract mentioned as words forest restoration or ecological restoration; (iii) studies that evaluate the use of species distribution modeling as an aid to forest restoration or restoration projects and programs the ecological. found 44 documents published in 30 scientific journals with an average of 3.91 publications per year; 18.55 citations per document; 197 authors, 3 documents with single authorship. Thus, we were able to conclude that the use of species distribution modeling for forest restoration in the world is very recent, and in Brazil it is incipient with low numbers of published articles. Still, it shows a growing trend due to its significant contribution to improving success rates restoration projects.

The way in which both the School and the University are currently structured shows a model of education that has existed for over a century. However, this same model is unable to sustain the new challenges of contemporary society. This reinforces the need for the development and application of new teaching methodologies and methods, which favor a change from the dominant mental model to systemic thinking, autonomy, innovation and the solution of real problems that motivate learners for effective learning. The Lego® Serious Play® methodology fulfills these functions, but it needs to be understood and used. Based on this context, this study aims to understand how the Lego® Serious Play® methodology can contribute to the qualification of autonomy and, as a consequence, of the results in the learning process in active learning environments in higher education, since this methodology is totally innovative and disruptive, provides great gains in engagement and productivity of the learners involved, in addition to enhancing skills in creativity, communication, cooperation and solving complex problems. The present study takes a methodological perspective based on the action research method; in relation to the technical procedures used, the bibliographical research and the case study stand out; as for the method of approach, the hypothetical-deductive method was chosen. It is concluded that the Lego® Serious Play® methodology appears as an alternative to contribute to improving the results of the learning process in active learning environments in higher education. Such methodology encourages autonomy, systemic thinking and transdisciplinarity, in which the learner needs to know the 'whole', developing a systemic, holistic and global view of the facts.

Objective: to verify the relationship between clinical manifestations and social, reproductive and pregnancy-related aspects in women and to prepare nursing diagnoses. Method: cross-sectional research with 30 pregnant women during prenatal in a northeastern city using the State - Trait Anxiety Inventory and a form for clinical manifestations of generalized anxiety disorder, with descriptive and inferential analysis. Results: There were statistical relations between number of prenatal visits and nervousness, sweating with ethnicity and with women with less than 20 weeks gestational age. Higher income was protective factor for dizziness and more than six prenatal visits is a protective factor for fear. Conclusion: Special attention to the clinical manifestations of anxiety should be given to non-white women over 26 years of age. Nursing diagnoses such as impaired sleep and altered rest pattern should be incorporated into the primary care plan.

The need to develop teaching methodologies that are, in fact, efficient for the construction of knowledge is indisputable. In this perspective, there are indications in the literature that the cooperative learning methodology is configured as a viable alternative, which contributes to greater interaction between those involved and the development of social and cognitive skills. Thus, this work aims to analyze the perception of high school students in relation to the contributions of that methodology, outlining its positive and negative points. Data collection took place through the application of previously structured questionnaires following the ethical criteria of the research, in 1st and 3rd year classes, comprising a sample of 42 students, whose participation was voluntarily. The results obtained show that the vast majority of students are in favor of the teaching methodology in question, classifying it as a determinant for their learning process, as it improves school performance and promotes the socialization of knowledge. Therefore, it is concluded that despite the problems mentioned by some students, the use of the cooperative methodology promotes greater interaction among students, with significant results in increasing school performance and in the acquisition of social skills.
