Uso de imagens como ferramenta facilitadora para trabalhar os conteúdos de biologia com estudantes da primeira serie do ensino médio em uma escola da rede estadual de ensino
(2017) Mendes, Suélen Pereira Marciano
The present work will address some daily aspects of Biology Teaching, with the main focus being to verify the importance of using images as a facilitating tool of the learning process. This approach was carried out through a descriptive field research with the application of an explanatory class of the content of Cytology and after the application of the questionnaire with a population sample of 30 students of the first high school of the public school, divided in two classes of the night shift. With a class the researcher explained the content cellular organelles without the use of images. With the other class, the same subject was worked, however, with the use of images projected by the data-show. After the class, the researcher applied a questionnaire, in order to verify aspects related to the students' learning about the topic studied. A comparison of the results of the two groups was made, based on the number of correct answers and with the aid of the Student's T-Test, the means of each class were made. Thus the results were achieved through their analysis and interpretation, with the hypothesis of answering the initial problem question, which is the efficiency or not of the use of images as a facilitating tool of the Biology learning process. Through the interpretation of all the data obtained in the research, it is noticed that when the Professor prepares his classes with the use of images as his pedagogical tool facilitates the development of learning of the content of Cytology, and among other contents of Sciences and Biology as Anatomy . Keywords: Learning. Picture. Biology.
Implicações do sistema de manejo de gado leiteiro na diversidade de besouros escarabeíneos e em sua função ecossistêmica de remoção de matéria orgânica
(2017) Heerdt, Lara das Neves
Dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) are organisms considered bioindicators due to the ecosystemic functions they perform. The objective of the research was to analyze the implications of the dairy cattle management system on the diversity of beetles and on the role of bovine manure removal by these organisms. In the period from December 2016 to March 2017, two livestock management systems were sampled, rotated and extensive, in the city of Armazém, Santa Catarina, Brazil, which had two replications each. For the capture of the beetles, we used standard methodology, with pitfall traps and lures of attraction (feces and fish), 10 matched traps were distributed in each sampling site by management system, totaling five sample points per area, spaced 50 m between. After 48 hours, the captured insects were removed and in the laboratory were identified, weighed and measured. For quantification of removal function by beetle beetles only the rotated system was sampled. We described the community structure and measured the rates of food resource allocation to be offered in three periods: 24, 48 and 72 hours. Regarding the diversity of dung beetles in the sampled livestock environments we registered a total of 104 specimens of beetle beetles, belonging to three species. In the rotated system, 80 individuals of beetle beetles were collected, while in the extensive system only 24 beetles fell into the traps. The number of species observed in each system studied was similar to the expected number of species based on the wealth estimator (Chao 1) and indicated sufficiency in the sampling, with a observed richness of at least 95.8%. Dichotomius nisus Oliver, 1789 was the only species shared in both types of systems sampled. The species: Dichotomius sericeus Harold, 1867 and Deltochilum multicolor Balthasar, 1939 were found only in the rotated system, suggesting that this system provides greater species richness. In terms of abundance, those who contributed the most in the systems studied were D. nisus. The physicochemical characterization of soils in the studied livestock environments showed that the D. nisus species correlated with soil organic matter content, suggesting the importance of these organisms in the nutrient cycling process. Removal of organic matter by dung beetles is influenced by precipitation, being higher in the 72 - hour period.
Influência do estado da barra de acesso em comunidades bênticas de uma lagoa intermitente e praia arenosa adjacente
(2018) Neto, João Martins
The structural connectivity gradient between the coastal lagoons and the sea alters the movement of resources and consumers, the internal physical-chemical gradients, and directly affects the regional diversity of species. Understanding the effects of the process of opening and closing bar on benthic fauna, and the consequent reflection in the trophic currents, is fundamental for better management of coastal areas. Thus, the study aimed to evaluate the influence of the access bar state on the benthic fauna of the Ibiraquera lagoon and the adjacent beach. For this, monthly sampling of benthic fauna and environmental variables was carried out in the Ibiraquera lagoon and on the adjacent sandy beach in a one-year period, covering two opening and closing cycles of the bar. The results indicate that, in general, the opening and closing dynamics of the bar causes changes in the structure of the benthic fauna, especially in the lagoon. The density of the macrofauna, meiofauna and the nematode assembly declines significantly after the bar opening. The descriptors of richness and diversity are also affected by the opening of the bar; for macrofauna and Nematoda both tend to decay, with greater intensity in the lagoon. As for meiofauna, the richness increases on the beach and decreases in the lagoon, while diversity has an increase in both places. The analyzes also showed that, while closed, the lagoon was less similar to the beach, and with the opening of the bar, there is an increase in similarity between environments. As for the interactions between the biotic data and the environmental variables, it was observed that in the periods when the lagoon was closed, the fauna was associated with higher concentrations of chlorophyll a, while the fauna of the beach, as well as of the lagoon in the periods of was associated with higher values of salinity and average grain size. Through this study, it is possible to perceive that the processes of opening and closing of the lagoon of Ibiraquera can negatively affect both the structure of the benthic fauna of the lagoon as well as the immediately adjacent beaches. Because these organisms form the basis of trophic chains, including species of commercial importance, flows from pond opening can play a key role in structuring environments and environmental services.
Analise de possíveis resíduos de formaldeído dos ovos comercializados na região da AMUREL provenientes do processo de desinfecção utilizado nas granjas aviárias
(2018) Garcia, Nícholas Tavares Koepp
The chicken egg is a low cost food, easy to prepare and can be consumed daily by the entire population. In addition to the use of egg whites and egg yolks in feed, the eggshell is also used as a base for other products. It is composed essentially of Calcium Carbonate, serving as a protective barrier against microorganisms, but it is absorbent, requiring this way of hygiene, in order to eliminate possible microorganisms that can penetrate the egg. There are several methods of disinfection, some of which are more effective than others for combating microorganisms. The most effective method is fumigation with Formalin and / or Paraformol, but they are not approved by several health agencies because they are carcinogenic. This study aimed to analyze the presence of possible formaldehyde residues from eggs marketed in the AMUREL region, from the disinfection process used in poultry farms. Therefore, contributing to the production of information and understanding of the need to produce safe eggs for consumption. The extraction of the contaminants was carried out according to the Environmental Protection Agency of the United States (U.S. EPA), method 1667 of the year 1998, which uses the principle of solvent extraction. Analysis of the data was adequate according to the reference article Determination of Formaldehyde in Cosmetics by HPLC Method and Acetylacetone Method of WU et al. (2003). From the analysis of 8 brands of eggs marketed in the region of AMUREL, it was possible to prove that there are traces, being that the highest concentration of the toxic is in the shell and could be harmful if used in large quantities in other products, the residues in the albumen are relatively low, presenting no problem related to the intake in short periods of time.

O processo de aprendizagem na disciplina de Biologia na visão dos estudantes matriculados no CEJA – Tubarão/SC
(2018) Martins, Joyce Fernandes
The teaching of biology has an important role in the development of notions of environment, conceptions, relationships existing between living and non-living beings, promoting discussions that allow understanding the universe and enabling the ability to reflect, evaluate and develop knowledge about biological procedures . Thus, this research had as objective to verify how is the learning process of the Biology discipline, in the view of the students enrolled in the JSCA - Tubarão / SC Adult Education Center of the state education network. In order to achieve this objective, a descriptive research was used, with a qualitative approach. Regarding the procedure of data collection, this is a field survey. As for the instruments for data collection, a questionnaire containing 15 open questions was used, according to Pinto (2009). With the answers to these questions it was possible: (a) to draw a profile of the population surveyed; (b) knowing the reasons that led the students to stop studying and the time they were stopped; (c) ascertain activities that were not attractive in the classroom and discover the concept of good teacher for these students; (d) raise the main difficulties presented in the discipline of Biology; and (e) verify the role of the school from the perspective of students enrolled in the JSCA. From the analysis of the data collected, it was possible to verify that the major cause of school dropout is due to the need to work and, among the students, most did not like evidence. The vision of the students of a good teacher is one who has patience and help in difficulties, clearly explaining the contents. In relation to the discipline of Biology, by the analysis of the data, the students presented no difficulties. In this way, it was also verified that the school fulfills its role of working with the students, knowledge historically constructed by the man, distributed in his curriculum, which follows the theoretical-methodological assumptions of the Curricular Proposal of the State of Santa Catarina . Therefore, contributing to the training of the student, in a process of learning from the needs of the students.
Panorama da febre amarela como doença reemergente no Brasil nos anos de 2007 a 2016
(2018) Gomes, Gabriel Barbosa
Yellow fever is an infectious, acute, febrile and hemorrhagic disease that is caused by a virus. Studying the behavior of this disease becomes important to generate data that contribute to the prevention and control of the vectors to be more effective, giving greater attention in the areas where the outbreaks are more frequent. Thus, the study aimed to evaluate the confirmed cases of yellow fever and its distribution in the period from 2007 to 2016 in Brazil. For this purpose, the epidemiological data on the confirmed cases of yellow fever in all Brazilian regions during the study period were collected from the SINAN (National Institute of Public Health Information System), and correlating them with this socio-demographic factors: race, age, sex, schooling and evolution of the disease. A panoramic profile of yellow fever has been drawn to better understand the behavior of the same. The results indicate that in this period, from 2007 to 2016, yellow fever occurred in all Brazilian regions, with the exception of the northeast region. The southeastern region had the highest rate of disease. Of the 169 people with yellow fever, 90 died. The cure of the disease happened in 53 cases. The majority of cases occurred in male and / or white individuals between the ages of 20 and 39, who mostly attended the incomplete eighth grade of elementary school. It is concluded that public health measures are still necessary to reduce the incidence of the disease and prevent further outbreaks. The alert for intensification of prophylactic measures should be highlighted as the risk of re-urbanization of yellow fever is high.
Perfil antimicrobiano de cepas de Escherichia coli, Klebsiella pneumoniae e Pseudomonas aeruginosa isoladas do rio Tubarão/SC
(2018) Wagner, Flávia da Silva
Freshwater in rivers is fundamental for the development of cities, but at the same time it presents itself as an important carrier of microorganisms of medical importance, such as Escherichia coli, Klebsiella spp. and Pseudomonas aeruginosa. The presence of these bacteria in the environment, together with the release of organic residues from diverse origins, contributes to the maintenance and multiplication of these bacteria in the environment and consequently optimizes the acquisition and dispersion of pathogenicity and resistance. Despite being a natural mechanism, anthropogenic activity has greatly influenced these processes and bacterial resistance to antibiotics is currently considered one of the major public health problems since many of these bacteria have become resistant to drugs that were commonly susceptible. Thus, the main objective of the present study was to trace the antibiotic resistance profile of strains of Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa isolated from the urban perimeter of the Tubarao River, in the Tubarao city / SC. Five superficial water samples were analyzed, using a filter membrane technique for bacterial isolation, in addition to 5 different culture media. To complement the bacterial identification was performed the Gram staining technique and to verify the sensitivity of the bacteria against the antibiotics was done AST, according to the Kirby-Bauer disk diffusion method. Bacterial growth was observed in all culture media and at all collection sites and the characteristic growth of E. coli, K. pneumoniae and P. aeruginosa was also observed at all of these points. The AST was made for these bacteria, P3 (73.3%), followed by P1 (53.3%), and finally P4 (44.4%). P. aeruginosa (77,7%), K. pneumoniae (59.9%) and E. coli (33.3%) were found to be the most resistant species to the antibiotics tested. However, from the obtained results we can identify the presence of potentially pathogenic microorganisms that are resistant to several antibiotics, and the isolation of these in the perimeter is of paramount importance for the well-being of the population.
A visão dos estudantes do ensino médio, do período noturno, de uma escola estadual localizada no município de Armazém/SC em relação ao uso de drogas lícitas e ilícitas
(2018) Boll, Cristina
The use of drugs by young people is related to addictions, addictions, biological, psychological, social factors, including the way society deals with adolescents, so-called illicit drugs, alcohol and narcotics. The purpose of the present study was to verify the vision of high school students, from the night time, of a state school located in the city of Armazém / SC in relation to the use of licit and illicit drugs. To reach the proposed objective, a field research was carried out, of the descriptive type with quantitative and qualitative approach. As a data collection instrument, a structured questionnaire was used, as proposed by Silva (2016), presenting 14 open-ended, closed and semi-open-ended questions. By analyzing the data obtained in the research, it was possible to show that the lack of information required by students' lack of occupation, leisure, sports and subsequent lack of supervision make these factors the main contributors to the growing rapprochement of young people to the drug world . This makes their experimentation with licit drugs such as alcohol and, consequently, illicit drugs, as cited in the study, marijuana more and more precocious.
As estratégias e os recursos didáticos no ensino de Ciências para o processo de ensino/aprendizagem de um aluno com Síndrome de Down: um estudo de caso
(2018) Uliano, Rafaela Beckhauser
This work aims to analyze the strategies and methods in the Teaching of Sciences used by teachers for the teaching / learning process of the student with Down Syndrome, in the Elementary School of the State Public School, 7th grade, in the municipality of Gravatal-SC . The methodological outline and level of deepening of this research is characterized as descriptive, with a qualitative approach. As for the data collection procedures, this is a documentary, bibliographical research and field case study and recorded interviews with semistructured questions. Considering the reflections and analysis of the data, it can be observed that among the activities most suitable for the second teacher are: clippings of figures, paintings and copies of key words. In what concerns the interaction of the regent professor of Sciences with the contents proposed for the student, he proceeded only in the practical classes. And the results achieved in this study allow a reflection on the inclusion process in schools, demonstrating the teachers' wishes about the teaching / learning process of students with disabilities. These facts are related to the lack of guidelines in their academic formations and the lack of support of the school team, which reflect in the student's process of inclusion and teaching / learning. Therefore it is possible to see the need for a redefinition of pedagogical practices and orientations of the educational system.
Perfil de suscetibilidade antimicrobiana de bactérias isoladas de água mineral
(2018) Matos, Aline Ávila
There is a perception that the consumption of natural mineral water represents a healthy style of life and that these products are relatively safe, free of impurities, which leads to increased potting and marketing of these waters. The lack of potability of water is not always perceptible to sight or smell, and a laboratory analysis is necessary to detect it. It becomes important the microbiological control of water due to its characteristic of transmission vehicle of bacteria, protozoa, viruses and fungi causing numerous diseases. These microorganisms are responsible for the occurrence of dysentery, hepatitis, cholera, among other serious diseases. For this reason, this research had as objective to analyze the presence of bacteria in mineral water samples commercialized in the city of Tubarão - SC and to evaluate the susceptibility of the isolated microorganisms to antibiotics. In the present study, fourteen mineral water samples of different brands were analyzed. The methodology used in the research for bacterial isolation was the filtering membrane technique in the media General Chromogenic Agar and Pseudomonas Agar. In order to complement the identification, Gram staining was performed, visualizing the morphology, arrangement and staining. The susceptibility profile to different antibiotics was measured by the Kirby-Bauer disk diffusion method. The results of this research revealed that, through microbiological analysis, eleven samples (78.57%) of mineral water presented microbial growth, 71.42% of which were bacteria (76.9% Gram negative and 23.1% Gram positive) and 14.28% fungi. As for the morphology, arrangement and coloration, the bacteria were mostly gram-negative bacilli (46,15%). In the TSA the highest resistance was observed for aztreonam (100%) and the most sensitive were amikacin, ampicillin, cefoxitin, gentamicin, sulfazotrim and tetracycline (0%). All Gram negative isolates were resistant to at least two antimicrobials. Thus, with the results obtained in this research, it is concluded that the mineral waters commercialized in the municipality of Tubarão demonstrate the presence of multiresistant bacteria, a fact that deserves attention due to the impact on public health.
Assembleia de besouros escarabeíneos em um gradiente ambiental de floresta atlântica no Sul de Santa Catarina
(2019) Da Silva, Bryan Goulart
The Atlantic Forest is one of the richest but most threatened biomes, especially due to habitat fragmentation and modification that affects their heterogeneity and, consequently, species richness and abundance. Scarab beetles (Coleoptera: Scarabaeinae) constitute a group considered bioindicator for having species susceptible to environmental changes. The present study evaluated how changes in habitat heterogeneity alter the composition and structure of assemblages of scarab beetles along an environmental gradient in southern Santa Catarina, Brazil. The study was conducted in six sample sites, were habitat structure was evaluated in order to define the disturbance levels of each site, creating an environmental gradient, being categorized as: preserved, intermediate and disturbed levels. For the collections, 18 baited fall traps (human feces and fish carcass) were used, arranged intercalated each sampling site. Three collections per site were performed between October 2018 and March 2019. Were collected total of 4,219 individuals distributed in eight genera and 22 species. Dichotomius sericeus (Harold, 1867) was the most abundant species at all levels of environmental disturbance. The results showed a 27.3% reduction in the richness of the scarab assemblages in the disturbed environment when compared to the preserved one. The presence of Dichotomius assifer (Eschscholtz, 1822) and Canthidium aff. trinodosum Boheman, 1858, were associated with preserved environments. The preserved and disturbed level environments were the ones that presented the biggest difference in the composition of the assembly. The intermediate level presented similarity in its composition with the other disturbance levels. With this study it was possible to describe the composition of the scarab beetle assemblage along a gradient of environmental disturbance, in the south of Santa Catarina, Brazil.
Decomposição de serrapilheira e atividade da fauna edáfica em diferentes fragmentos de Mata Atlântica
(2019) Nandi, Marcos Vieira
The litter is an important component of the cycling of nutrients, essential for the maintenance of forests, especially in environments with weathered soil as in tropical forests. The ecosystem processes are regulated by biotic and abiotic factors directly dependent on the edaphic community, composed especially by invertebrates. The objective of this study was to estimate the litter decomposition rate in two soil matrices (cambisol and clayey) in fragments of Atlantic forest; as well as describing the functional diversity of soil fauna present in the process. This study was conducted in forest fragments with different ground matrices in the cities of Lauro Müller (28º21'S; 49º27'W; height: 220 m, cambisol soil matrix) and shark (28º27'S; 49º03'W; height: 6 m, clay soil matrix) in the southern state of Santa Catarina, Brazil. For the capture of individuals, pitfall traps type without the presence of baits were used. The captured organisms were identified at the lowest possible taxonomic level and grouped into functional groups. The sampling protocol in each area consisted of 20 fixed points, being carried out in two campaigns for each soil matrix. To evaluate the litter decomposition, senescent leaves of Rheedia gardneriana Tr. & Planch. (Clusiaceae), confined in nylon bags (Litter bags). Were used bags with 8 mm mesh, allowing the access of the edaphic fauna and bags with mesh inferior to 2 mm, representing the exclusion of edaphic fauna; these bags were then packed in overhang and buried portions, distributed in 15 sample points. To collect this material, it was stipulated a period of stay in the field 30, 60 and 90 days. A total of 3,161 individuals of soil fauna was recorded in the two soil matrices studied. A pattern of dominance of functional groups in these two soil matrices, represented by sapphagus, followed by sapphagogens predators and predators was observed. The observed pattern of bed decomposition rate in soil matrix types showed a high degree of proximity. The breakdown was faster in the first 30 days of exposure; between the periods 30 and 60 days there was a breakdown in the stability and between 60 and 90 days there was a resumption of the litter decomposition cycle. These results suggest that the soil fauna along with the microbiota are the main characters in the decomposition of litter, but the physical and chemical agents are also relevant for this process. In the two matrices surrounding soil there was a decomposition of 35 and 58.4%, demonstrating the high capacity of nutrient cycling of the Atlantic. Found that the presence of the roots 60 and 90 days confirming the litter as an important agent of nutrient cycling, making it essential to the aid of the litter seed bank system and forest management and reclamation.
Avaliação da atividade larvicida de sais imidazólicos sobre Aedes albopictus (Skuse, 1894) (Diptera: Culicidae)
(2019) Gonçalves, Douglas Zelinger
The Aedes albopictus (Skuse, 1894) mosquito is considered a vector of medical importance because it has vector capacity in the laboratory for 22 arboviruses, including dengue, chikungunya and yellow fever viruses. The present study aimed to evaluate the larvicidal activity of the imidazolium salts (IS) C16MImMeS and C18MImCl against A. Albopictus larvae. For this, larvae of Ae. albopictus of 3rd final instar and/or 4th initial instar were exposed to 11 different concentrations (ranging from 0.5ppm to 10ppm) of C16MImMeS and C18MImCl. The bioassay was performed in triplicate, containing 20 larvae in each replicate and using purified water as control. It was conducted at a temperature of 25°C with a relative humidity of 80% (± 10%) in a climate chamber. Larval mortality was evaluated at 24 and 48 hours of exposure of the larvae to the solutions, being considered dead larvae that did not move when touched. For the results analysis, the variance test (ANOVA) was performed, with significant values of p≤0.05. Lethal concentrations, those that caused 50% mortality (LC50) were calculated by the Probit program. The IS C16MImMeS and C18MImCl showed larvicidal activity against A. albopictus at 24 and 48h exposure. At the lowest concentration (0.5ppm) of C16MImMeS and C18MImCl, mortality was 6.6 and 23.3%, at the highest concentration (10ppm) mortality was 85 and 100%, respectively. The 50% lethal concentrations (LC50) of IS C16MImMeS and C18MImCl at 48h exposure were 2.35ppm and 3.61ppm, respectively. Imidazolium salts C16MImMeS and C18MImCl have larvicidal potential against A. albopictus, being the first study to demonstrate the use of these IS to control A. albopictus. Further studies are necessary to understand its behavior in pupae and mosquito adulthood, its mechanism of action, and possible resistance factors.
A contribuição do programa residência pedagógica para a formação inicial dos professores de ciências e biologia
(2019) Santos, Maria Ester Bueno
The Brazilian educational scenario is challenging. In this sense, the development of initial training programs offered to undergraduates for quality improvement in public basic education is important. Thus, the objective of this research was to evaluate the contribution of the Pedagogical Residency Program to the initial formation of future teachers of Science and Biology from the perspective of the participants of this program, developed by the University of Southern Santa Catarina. Respecting the legislation, the project was submitted to Unisul's Research Ethics Committee (CEP) and approved with opinion number 3.641.686. As for data collection, a field research was used in the form of a descriptive case study with a qualitative and quantitative approach. Data collection was done through questionnaires: for resident fellows, for preceptors, for the advisor teacher and for the institutional coordinator at the university. Each quiz contained three open questions and four closed questions. The questionnaires were applied to all twenty-one residents of the Biological Sciences course who are part of the Pedagogical Residency Program at Unisul, with their respective preceptors (five in total), with the advisor teacher representing the Biological Sciences Course and with the institutional coordinator of the University's Pedagogical Residency Program, adding a total of twenty-eight participants. For the analysis of the collected data, the Microsoft Exel program was used, in which all the information was placed for a quantitative analysis of the data, through graphs and tables. For the qualitative analysis, the Microsoft Word program was used, in which all the questionnaires with the answers were placed. The open questions were categorized and analyzed qualitatively and quantitatively. Through this study it can be verified that the actions foreseen in this program are being developed and are contributing to the teacher education. As weak points for the development of the program were the precariousness and lack of materials, both by a resident and preceptors, and the lack of qualified teachers in the various areas of knowledge of the field schools.
Avaliação da percepção de docentes e discentes da unisul sobre a doação voluntária de corpos para estudo e pesquisa em anatomia humana
(2019) Cruz, Peterson
This study aimed to evaluate the perception of teachers and students of the courses of the Academic Unit of Health and Social Welfare of the University of Southern Santa Catarina, at campus Tubarão, on the voluntary donation of bodies for the study and research in human anatomy. The methodological approach of this research was characterized as quantitative, as the objectives, descriptive research of transversal character. Data were collected through two instruments, a sociodemographic questionnaire and another aiming to understand the perception of Unisul’s teachers and students. The questionnaire was applied to a total of 9 teachers who teach Human Anatomy classes. The students, in a total of 282, study in courses related to the Academic Unit of Health and Social Welfare of the University of Southern Santa Catarina, campus Tubarão, on the 2019/2 semester. The results showed that, regarding gender, the distribution in teachers is 1:1, while most participating students are women. Both teachers and students demonstrated to know or have heard about the voluntary donation of bodies, but when asked if they knew the legislation 66.67% of teachers said yes and more than 90% of students said no. On the question whether they would donate their own body or relatives’, in both cases most would not donate for various reasons, from preferring to be buried - which is what occurred in most questionnaires -, to the family that, for cultural reasons, do not accept or are afraid of being recognized. The subject of death is still a taboo in local culture, causing discomfort in some people. Thus, we conclude in the present study that most teachers and students would not donate the body, but studies show that younger people are less likely to volunteer. It is noticeable that people non-related to health care feeling motivated to become useful after death or in gratitude to science are most susceptible to voluntary donation. However, there is a need for this theme to be more publicized, not only in academia but also in society in general, since the lack of human cadavers for studies is imminent and one of the efficient ways to combat this scarcity of material can be through voluntary body donation programs. Many universities, both in Brazil and in other countries, are already using this type of program with positive results.

Avaliação da música no desenvolvimento do sistema nervoso: implicações no aprendizado e memória
(2019) Peretti, Eduardo de Medeiros
Em diversas culturas a música é utilizada como forma de tratamento para diversas condições físicas ou mentais. Entretanto, ainda não se sabe ao certo como a música afeta o corpo humano, principalmente num sentido fisiológico. Mais desconhecidos ainda são os mecanismos neurais afetados pela música. O objetivo deste estudo foi investigar os efeitos da exposição pré-natal a distintos estímulos auditivos, em ratos Wistar com diferentes idades. Foram acasaladas 12 fêmeas com 4 machos para obtenção da prole. As fêmeas foram divididas em quatro grupos experimentais e expostas aos protocolos intermitentes de enriquecimento ambiental, sendo eles: Silêncio; Ruído Branco; Música Clássica; e Música Clássica Retrógrada. Para avaliação do desempenho cognitivo na prole, foram utilizados os testes de reconhecimento de objetos e esquiva inibitória, para avaliação das memórias declarativa e aversiva, respectivamente. Os resultados mostraram que a exposição pré-natal a música clássica promoveu melhor desempenho cognitivo em animais avaliados com 70 dias de vida quando comparados ao desempenho de animais mais jovens. Desta forma, este estudo sugere que a exposição pré-natal a música clássica pode auxiliar na formação de novas memórias e desenvolvimento cognitivo, facilitando o aprendizado em período pós-natal.
Presença de Cryptosporidium SPP. e Giardia SPP. na Lagoa de Ibiraquera, em fevereiro de 2019, Imbituba- SC
(2019) Abreu, Elena Silveira
The anthropogenic actions caused to the water resources ended up causing a decline in the quality of the water, and consequently causing damages to public health. The most important constituent of all living organisms, a fundamental element in life, is represented by water, an element which, in the present conditions of degradation caused by the actions of human beings, serves as a vehicle for the transmission of diseases. The pathogenic protozoa Cryptoporidium spp., Giardia spp., are microorganisms that can be found in this environment and are the result of fecal contamination. These microorganisms cause diseases that can present in a mild and even severe or fulminant way in immunocompromised individuals. In the Ibiraquera’s lagoon, located in the town of Imbituba / SC, there is a large increase in the number of constructions surrounding the lagoon in recent years, and possible deficiencies in its sanitary structure - domestic sewage - which may allow the arrival of contaminants in this environment. The present study had as main objective to evaluate the presence of protozoa of the genus Giardia spp. and Cryptosporidium spp. as well as environmental characteristics that favor the presence of these agents, in February of 2019 in the Ibiraquera’s lagoon, Imbituba / SC. The identification of protozoa was performed using the membrane filtration technique, associated with Ziehl Neelsen staining and microscopy. After the collection, processing and analysis of the samples, the occurrence of oocytes and cysts of the protozoa under study was confirmed, present in 59% of collection points, distributed in the sampled area, but with a higher concentration in the area closest to the urban constructions. movement of bathers. The factors associated with the distribution of protozoa in the Ibiraquera’s lagoon are related to wind, recreation activities and the resistance of infective agents in the environment. The results seek to contribute to an improvement of the studied environment, through the sensitization of the local community, since the presence of these pathogens was confirmed.
