Abstract: Memorable tourism experiences have become progressively relevant to the context of rural tourism. To meet the expectations of tourists, producers and local managers must know the characteristics of memorable experiences to structure tourist products that tourists remember positively, influencing their attitudes and behaviors during and after their trip. This paper aims to investigate the process of developing techniques and knowledge to create memorable tourism experiences with family farmers. A qualitative study was carried out using the action research method, with 17 cheese marketers from 9 municipalities in the Campo das Vertentes region in Minas Gerais. The methodological strategies used were remote workshops, questionnaires to create experiences via Google Forms, field visits and notes in the researchers’ electronic diary. The remote workshops were divided into five stages and resulted in 12 experiences. We found that with the intervention of the workshops, family farmers were able to develop a plan with the researchers to offer memorable tourist experiences, considering aspects of identification, characterization, and commercialization of products. The main result of this research was the construction of knowledge with family farmers to promote autonomy to offer tourist experiences with innovation, technical quality, and hospitality. The 12 experiences created demonstrate that rural producers could associate the knowledge systematized in the workshops with their local realities and natural and cultural resources.

Resumen: Las experiencias turísticas memorables se han vuelto cada vez más relevantes en el contexto del turismo rural. Para cumplir con las expectativas de los turistas, los productores y gestores locales deben conocer las características de las experiencias memorables para estructurar productos turísticos que sedimenten positivamente en la memoria de los turistas, influyendo en sus actitudes y comportamientos durante y después del viaje. En este artículo, el objetivo fue investigar el proceso de desarrollo de técnicas y conocimientos para la creación de experiencias turísticas memorables con agricultores familiares. Se realizó un estudio cualitativo, utilizando el método de investigación-acción, con 17 productores agroalimentarios de 9 municipios de la región de Campo das Vertentes en Minas Gerais. Las estrategias metodológicas utilizadas fueron talleres a distancia, cuestionarios para crear experiencias a través de Google Forms, visitas de campo y notas en el diario electrónico de los investigadores. Los talleres remotos se dividieron en cinco etapas y dieron como resultado la creación de 12 experiencias. Se encontró que, con la intervención de los talleres, los agricultores familiares lograron desarrollar un plan con los investigadores para ofrecer experiencias turísticas memorables, considerando aspectos de identificación, caracterización y comercialización de los productos. El principal resultado de esta investigación fue la construcción de conocimiento con agricultores familiares con el fin de promover la autonomía para ofrecer experiencias turísticas con innovación, calidad técnica y hospitalidad. Las 12 experiencias creadas muestran que los productores rurales lograron asociar los saberes sistematizados en los talleres con sus realidades locales y los recursos naturales y culturales.

Resumo: Experiências turísticas memoráveis vêm se tornando progressivamente relevantes para o contexto do turismo no espaço rural. Para atender às expectativas de turistas, produtores e gestores locais devem conhecer as características das experiências memoráveis com o propósito de estruturar produtos turísticos que se sedimentem positivamente nas lembranças dos turistas, influenciando suas atitudes e comportamentos durante e após as viagens. Neste artigo, objetivou-se investigar o processo de desenvolvimento de técnicas e conhecimentos para a criação de experiências turísticas memoráveis junto a produtores da agricultura familiar. Realizou-se um estudo qualitativo, empregando o método da pesquisa-ação junto a 17 produtores agroalimentares de nove municípios da Região do Campo das Vertentes, em Minas Gerais. As estratégias metodológicas utilizadas foram oficinas remotas, questionários para criação de experiências via Google Forms, visita de campo e anotações em diário eletrônico dos pesquisadores. As oficinas remotas dividiram-se em cinco etapas e resultaram na criação de 12 experiências. Constatou-se que, com a intervenção das oficinas, os agricultores familiares foram capazes de elaborar junto aos pesquisadores um plano de oferta de experiências turísticas memoráveis, considerando aspectos de identificação, caracterização e comercialização dos produtos. O principal resultado desta pesquisa foi a construção de conhecimentos junto aos agricultores familiares de modo a promover autonomia para a oferta de experiências turísticas com inovação, qualidade técnica e hospitalidade. As 12 experiências criadas evidenciam que os produtores rurais foram capazes de associar os conhecimentos sistematizados nas oficinas com suas realidades locais e recursos naturais e culturais.

Resumo O presente artigo oferece uma perspectiva sobre o turismo no Brasil, analisando os principais desdobramentos com foco no período de 2000-2019. Trata-se de um artigo de opinião com reflexões de acadêmicos do turismo brasileiro. Os tópicos relacionados ao turismo, cobertos neste artigo, incluem economia, política e planejamento, marketing, transporte, meio ambiente, gastronomia, hospitalidade, lazer, entre outros. Como principal conclusão, considera-se que o Brasil não conseguiu se posicionar como destino de renome internacional, já que desde a década de 1990 os esforços para apoiar o desenvolvimento do turismo regional obtiveram sucesso apenas moderado. As crises econômicas, a instabilidade política, a violência e a corrupção foram entraves que afetaram consideravelmente o setor de turismo. A falta de uma abordagem coordenada entre os vários níveis de governo, a escassez de dados de turismo e uma campanha de marketing supra-governamental de longo prazo, entre outros fatores, fizeram com que o país perdesse várias oportunidades importantes na década de 2010 para se estabelecer como um dos principais destinos turísticos no mercado global.

Abstract This article provides a perspective on tourism in Brazil, analyzing the main developments focusing on the period 2000-2019. This opinion paper provides a reflection made by academics with expertise in tourism in Brazil. Tourism-related topics covered in this paper include economics, politics and planning, marketing, transportation, environment, gastronomy, hospitality, leisure, among others. As the main conclusion, it is argued that Brazil has not managed to position itself as an internationally renowned destination. The efforts in the 1990s to support the development of regional tourism have had only moderate success. Economic crises, political instability, violence and corruption were obstacles that considerably affected the tourism sector. The lack of a coordinated approach between the various levels of government, the shortage of tourism data and a long-term supra-governmental marketing campaign, among other factors, meant that the country missed several opportunities in the 2010s to become established as one of the top tourist destinations in the global market.

Resumen El artículo ofrece una perspectiva del turismo en Brasil, analizando los principales desarrollos con un enfoque en el período 2000-2019. Es un artículo de opinión con reflexiones de investigadores del turismo brasileño. Los temas relacionados con el turismo que se tratan en este artículo incluyen economía, política y planificación, marketing, transporte, medio ambiente, gastronomía, hostelería, ocio, entre otros. Como conclusión principal, se considera que Brasil no ha logrado posicionarse como un destino de renombre internacional, ya que desde la década de los noventa los esfuerzos para apoyar el desarrollo del turismo regional solo han tenido un éxito moderado. Las crisis económicas, la inestabilidad política, la violencia y la corrupción fueron obstáculos que afectaron considerablemente al sector turístico. La falta de un enfoque coordinado entre los distintos niveles de gobierno, la escasez de datos turísticos y una campaña de marketing supra gubernamental a largo plazo, entre otros factores, hicieron que el país perdiera varias oportunidades importantes en la década de 2010 para establecerse como uno de los principales destinos turísticos del mercado mundial.

Abstract: En | Text: En | PDF: En

Abstract Squash is a food that meets the requirements of a healthy diet and is highly appreciated by consumers for its mild flavour and high nutritional value. In southern Brazil, many farmers grow several pumpkin landraces that are widely used in food. The consumption of its fruits and derivatives benefits human health due to the bioactive compounds, minerals, and antioxidants in the fruit pulp, making pumpkin a functional food. The objective of this study was to characterize the bioactive compounds, antioxidant activity, and minerals in the pulp of fruits of pumpkin landraces (Cucurbita maxima) from southern Brazil. Phenolic compounds, carotenoids, antioxidant activity, and minerals were evaluated in 10 accessions of pumpkin landraces from the Cucurbitaceae Genebank of Embrapa Temperate Agriculture (Pelotas, RS, Brazil). In mature fruits, the seeds and peels were discarded, and opposite longitudinal slices of pulp were manually prepared for analysis. All analyses were performed in triplicate. The data obtained showed genetic variability in total phenolic compounds, carotenoids, antioxidant activity, and minerals. Accessions C49, C307, and C216 had high levels of total phenolic compounds and carotenoids and high antioxidant activity. Of these accessions, accession C49 had the highest antioxidant capacity (504.1 μg·g-1). C216 and C178 were high in copper and iron, and the latter was highest in potassium, calcium, and phosphorus. Thus, accessions C216 and C178 have great potential for exploitation by genetic improvement programs for the development of biofortified cultivars in efforts to promote consumer health.

ABSTRACT Objective: To identify the clinical and epidemiological profile of adult intensive care units in Brazil. Methods: A systematic review was performed using a comprehensive strategy to search PubMed®, Embase, SciELO, and the Biblioteca Virtual em Saúde. The eligibility criteria for this review were observational studies that described the epidemiological and/or clinical profile of critically ill patients admitted to Brazilian intensive care units and were published between 2007 and 2020. Results: From the 4,457 identified studies, 27 were eligible for this review, constituting an analysis of 113 intensive care units and a final sample of 75,280 individuals. There was a predominance of male and elderly patients. Cardiovascular diseases were the main cause of admission to the intensive care unit. The Acute Physiology and Chronic Health Evaluation II score was the most widely used disease severity assessment system. The length of stay and mortality in the intensive care unit varied widely between institutions. Conclusion: These results can help guide the planning and organization of intensive care units, providing support for decision-making and the implementation of interventions that ensure better quality patient care. Registration PROSPERO: CRD4201911808.

Resumo Avaliar e correlacionar o estado funcional (EF) e a força muscular (FM) em adultos jovens, adultos e idosos em Unidade de Terapia Intensiva (UTI). Coorte prospectiva com 48 pacientes avaliando EF por meio do Functional Status Score for the Intensive Care Unit (FSS-ICU) e FM pelo Medical Research Council Sum-Score (MRC-SS) e força de preensão palmar (FPP), no despertar e na alta da UTI. Dados analisados pelos testes Kruskall-Wallis, Qui-quadrado, Wilcoxon e Correlação de Sperman. Na comparação do despertar em relação à alta, o EF e o MRC-SS foram maiores na alta em todos os grupos, com menor ganho nos idosos. A FPP aumentou bilateralmente na alta, exceto no grupo de adultos, pois apresentavam valores maiores no despertar. Na comparação dos grupos, o FSS-ICU foi maior nos adultos no despertar e alta, e a FPP-D menor nos idosos. O EF apresentou forte associação com a FM em adultos jovens e adultos, pois ambos apresentam progressiva melhora durante a permanência na UTI. Os idosos apresentam menor ganho do estado funcional, além de apresentarem menor força muscular desde o despertar. Estas variáveis apresentam importante associação apenas nos adultos jovens e adultos, considerando a natureza multifatorial do processo de adoecimento e incapacidade nos idosos.

Abstract The aim of this study was to analyze and assess the association between functional status (FS) and muscle strength (MS) in young adults, adults and older adults in an intensive care unit (ICU). We conducted a prospective cohort study with 48 patients. FS was assessed using the Functional Status Score for the Intensive Care Unit (FSS-ICU) and MS was measured using the Medical Research Council Sum-Score (MRC-SS) and by testing handgrip strength (HS). The assessments were performed on awakening and ICU discharge. The data were analyzed using the Kruskall-Wallis, chi-squared, Wilcoxon and Spearman’s correlation tests. FS and MRC-SS scores were higher on ICU discharge in all groups. Gains were lowest in the older adult group. HS was greater in both hands on ICU discharge in all groups except the adults. FSS-ICU on both awakening and ICU discharge was highest in the adults; HS-R was lowest in the older adults. There was a strong association between FS and MS in the young adults and adults. FS and MS showed progressive improvement during ICU stay. Gains in FS and MS on awakening and ICU discharge were lowest among the older adults. Important associations were found between these variables in all groups except the older adults. This can be explained by the multifactorial nature of illness and incapacity in this group.

Resumo Um inventário de fanerógamas da planície costeira da região centro-norte do Rio Grande do Sul, Brasil é apresentado. Durante dois anos, todas as fitofisionomias dos municípios de Cidreira, Balneário Pinhal e Palmares do Sul foram amostradas. As espécies foram classificadas quanto ao ambiente de ocorrência, hábito preferencial, naturalidade e grau de ameaça. Foram coletadas 383 espécies de 92 famílias, sendo 365 (95%) nativas e 18 (5%) exóticas. As famílias de maior riqueza foram Asteraceae (45), Poaceae (30), Cyperaceae (24) e Fabaceae (23). As formações campestres apresentaram a maior riqueza florística (146), seguidas pelas florestais (132) e lacustres (17). Os hábitos preferenciais foram herbáceo/arbustivo (68%), árvore (20%), trepadeiras (6%), epífitas (6%) e parasitas (1%). Ao todo, foram registradas 18 espécies em alguma categoria de ameaça. Os dados encontrados representam uma alta riqueza de espécies para região sendo compatíveis às estimativas e ao encontrado por outros autores em áreas costeiras, e devem-se basicamente pelo mosaico fitofisionômico e geográfico da região e pela influência dos biomas Mata Atlântica e Pampa. Ameaças à flora local foram evidenciadas, principalmente relacionadas à degradação dos habitats naturais pelos cultivos agrícola e silvícola.

Abstract An inventory of phanerogams from the central-north coastal plain of Rio Grande do Sul, Brazil, is presented here. During two years, all the phytophysiognomies of the municipalities of Cidreira, Balneário Pinhal and Palmares do Sul were sampled. The species were classified according to the environment of occurrence, preferential habit, naturalness and degree of threat. A total of 383 species were collected from 92 families, of which 365 (95%) native and 18 (5%) were exotic. The richest families were Asteraceae (45), Poaceae (30), Cyperaceae (24) and Fabaceae (23). The field formations presented the highest floristic richness (146), followed by forest (132) and wetland (17). The preferred habits were herbaceous and shrub (68%), habit tree (20%), climbers (6%), epiphytes (6%) and parasites (1%). In all, 18 species were registered in some threat category. The data found represent a high species richness for the region, and are compatible with the estimates and those found by other authors in coastal areas, and are basically due to the phytophysiognomic and geographic mosaic of the region and the influence of the Mata Atlântica and Pampa biomes. Threats to the local flora were evidenced, mainly related to the degradation of the natural habitats by the agricultural and silvicultural crops.

Abstract The aim of this study was to investigate the effects of yerba mate (Ilex paraguariensis St. Hil.) extract (YME) on oxidative stress parameters and pathological changes in the lungs of mice chronically exposed to hand-rolled cornhusk cigarette (HRC) smoke. Twenty-four male Swiss mice were divided into four groups exposed to the following treatments: control (ambient air), HRC, YME, and HRC plus YME. The animals were exposed to four HRCs per session, with 3 sessions/day, every day for 30 days. Twenty-four hours after the last inhalation, the mice were killed, and the left lungs were removed. The results showed that HRC contains elevated levels of tin and carbon oxide, but less arsenic, cobalt, manganese, and selenium than commercial cigarettes. YME administration reversed fibrosis, alveolar enlargement, and hemorrhage induced by HRC smoke. In addition, the YME and HRC significantly reduced the production of oxidants, oxidative damage and promoted a significant increase in total thiol. In conclusion, exposure to HRC smoke compromised pulmonary histoarchitecture by promoting structural changes and increasing oxidative stress in tissues. However, concomitant treatment with YME regulated the redox state and reduced the harmful effects of HRC smoke exposure in the lungs.

Abstract The objective of this work was to evaluate the genetic variability for the synthesis of bioactive compounds and minerals in pumpkin (Cucurbita moschata) landraces. Total phenolic compounds, carotenoids, antioxidant activity and minerals were evaluated in 10 accessions of Cucurbita moschata landraces from the Genebank of Embrapa Temperate Agriculture (Pelotas - RS, Brazil). Twenty plants of each accession were cultivated in the field during the spring/summer of 2013/2014. After harvesting of mature fruits, the seeds were discarded and opposite longitudinal portions of the pulp were manually prepared for analysis of the bioactive compounds. For the determination of minerals, pumpkin samples were frozen in plastic bags, and after freeze-dried and milled. All analysis were performed in triplicate. The data obtained showed high genetic variability for the synthesis of phenolic compounds, carotenoids, antioxidant activity and minerals. The accessions C52, C81, C267 e C389 showed high levels of antioxidants and minerals, being recommended for use in pumpkin breeding programs. The accessions C52 and C389 are promising, especially because they present the highest levels of total carotenoids.

This study describes the life cycle of Agrotis malefida Guenée, 1852 (Noctuidae: Noctuinae) under laboratory conditions. The insects were reared in a controlled environment (25 ± 1ºC, 70 ± 10% RH and 14 hours photo phase) and observed daily. The larvae were fed Greene's artificial diet and adults were offered a 10% sucrose solution. The viability and duration of immature stages were assessed. The experiment initiated with 2,410 eggs. Larvae were isolated shortly after hatching. Longevity, pre-, post- and oviposition, fecundity and fertility of 13 adult couples were also evaluated. The viability of eggs, larvae, pupae and pre-pupae was 96.72, 91.25, 78.37 and 95.26%, respectively. The average duration of egg, larva, pre-pupa, pupa and adult was 7.93, 54.26, 61.61, 37.43 and 12.85 days, respectively. The immature stage of A. malefida lasted an average of 161.29 days, ranging from 102 to 227 days. The life cycle of A. malefida is much longer than that of congeners. The mean fecundity was 1,696.77 eggs and fertility 1,641.15 larvae per female. Under the conditions in which the study was conducted, the biotic potential of A. malefida was of 606,666.59 individuals/female/year. The results also indicated that this species goes through larval (pre-pupae) and pupal diapause.

Abstract: En | Text: En | PDF: En

Climate change can be associated with variations in the frequency and intensity of extreme temperatures and precipitation events on the local and regional scales. Along coastal areas, flooding associated with increased occupation has seriously impacted products and services generated by marine life, in particular the biotechnological potential that macroalgae hold. Therefore, this paper analyzes the available information on the taxonomy, ecology and physiology of macroalgae and discusses the impacts of climate change and local stress on the biotechnological potential of Brazilian macroalgae. Based on data compiled from a series of floristic and ecological works, we note the disappearance in some Brazilian regions of major groups of biotechnological interest. In some cases, the introduction of exotic species has been documented, as well as expansion of the distribution range of economically important species. We also verify an increase in the similarities between the Brazilian phycogeographic provinces, although they still remain different. It is possible that these changes have resulted from the warming of South Atlantic water, as observed for its surface in southeastern Brazilian, mainly during the winter. However, unplanned urbanization of coastal areas can also produce similar biodiversity losses, which requires efforts to generate long-term temporal data on the composition, community structure and physiology of macroalgae.
