Throughout this research, 230 Trichoptera specimens were collected in the area of Konavle area, the southernmost region of Croatia. Altogether 21 species, 15 genera and 11 families were identified. DNA barcoding covered 41 specimens represented with 15 species collected in the Konavle region. The highest number of species was recorded at two localities: the spring of the River Ljuta (13) and a spring in the village Vodovađa (8). The highest number of taxa (4) was recorded within the following two families: Hydroptilidae and Hydropsychidae. From a faunistic point of view, the most interesting species in Konavle region are: Agapetus cf. kampos Oláh (the first record for Croatia), Hydroptila martini Marshall (the first record for the Mediterranean part of Croatia), Oxyethira falcata Morton (the first record for Croatia), Tinodes andrasi Oláh (type locality of the species is River Ljuta), Diplectrona cf. afra McLachlan (the first record from the Mediterranean part of Croatia) and Micropterna wageneri Malicky (the second record for Croatia). The first DNA barcoding data for the species Agapetus cf. kampos Oláh and Tinodes andrasi Oláh were entered into the BOLD database. The area of Konavle represents one of the most interesting regions for the fauna of Trichoptera and can be considered as a ”hotspot” for caddisflies in Croatia. Thus, it is necessary to install high standards for their protection.

Published: January 2022

The caddisfly fauna of North Africa and Morocco is still poorly known, with only a few historical and recent investigations, carried out sporadically. In this paper we describe a new species, Tinodes atlasensis Ibrahimi, Mabrouki & Taybi, sp. nov. from the Atlas Mountains in Morocco. The new species is closest to Tinodes baenai Gonzales & Otero, 1984, known from the Iberian Peninsula and mainly differs by the shape of segment IX, coxopodites, harpago and the process of basal plate. Tinodes atlasensis Ibrahimi, Mabrouki & Taybi, sp. nov. is the seventh known species of the genus Tinodes Curtis, 1834 from Morocco. Future caddisfly investigations in this North African country will most certainly increase the number of the known species and reveal other new ones.

While investigating the aquatic macroinvertebrate fauna of four intermittent Dinaric karst rivers in Croatia, we confirmed or recorded new distribution data and ecological features for several mayfly species rare in Croatian freshwater habitats: Nigrobaetis niger (Linnaeus, 1761), Procloeon pennulatum (Eaton, 1870) and Paraleptophlebia werneri Ulmer, 1920. To our knowledge, this is the first record of N. niger in intermittent lotic habitats. We discuss their substrate preferences in the studied habitats as well as their relationships with measured physico-chemical water parameters. The newly obtained results confirm that our knowledge about Croatian mayfly fauna and species ecological requirements in intermittent Mediterranean rivers is still incomplete and is increasing with systematic studies.

Interesting records of one bush-cricket and two grasshopper species are reported from Croatia and Slovenia. Rhacocleis annulata Fieber, 1853 (Tettigoniidae: Tettigoniinae) has been reported for the first time from Croatia (Dubrava by Šibenik), as well as for Slovenia (Borovnica SW of Ljubljana); Eyprepocnemis plorans (Charpentier, 1825) (Acrididae: Eyprepocnemidinae) is reported for the first time for Croatia, also from Dubrava; and finally, the Xya pfaendleri Harz, 1970 (Tridactylidae: Tridactylinae) record from Dubrava represents the first record of this species from Dalmatia. Rhacocleis annulata and Eyprepocnemis plorans are known to be spreading through Europe, so these records contribute to the understanding of their dispersal in Southern Europe. Croatian Orthopteran fauna now counts, with two species added, 187 species, while Slovenian Orthopteran fauna now counts, with one species added, 158 species.
On the existence and uniqueness of a positive solution to a boundary value problem for a nonlinear ordinary differential equation of even order
Authors: Abduragimov Gusen E. , Abduragimova Patimat E. , Kuramagomedova Madina M.
Published: January 2022

In the article, we consider a boundary value problem for a nonlinear ordinary differential equation of even order which, obviously, has a trivial solution. Sufficient conditions for the existence and uniqueness of a positive solution to this problem are obtained. With the help of linear transformations of T. Y. Na [T. Y. Na, Computational Methods in Engineering Boundary Value Problems, Acad. Press, NY, 1979, ch. 7], the boundary value problem is reduced to the Cauchy problem, the initial conditions of which make it possible to uniquely determine the transformation parameter. It is shown that the transformations of T. Y. Na uniquely determine the solution of the original problem. In addition, based on the proof of the uniqueness of a positive solution to the boundary value problem, a sufficiently effective non–iterative numerical algorithm for constructing such a solution is obtained. A corresponding example is given.
On ring solutions of neural field equations
Authors: Atmania Rachid , Burlakov Evgenii O. , Malkov Ivan N.
Published: January 2022

The article is devoted to investigation of integro-differential equation with the Hammerstein integral operator of the following form:
∂_t u(t,x)=-τu(t,x,x_f )+∫_(R^2)▒〖ω(x-y)f(u(t,y) )dy, t≥0, x∈R^2 〗.
The equation describes the dynamics of electrical potentials u(t,x) in a planar neural medium and has the name of neural field equation.We study ring solutions that are represented by stationary radially symmetric solutions corresponding to the active state of the neural medium in between two concentric circles and the rest state elsewhere in the neural field. We suggest conditions of existence of ring solutions as well as a method of their numerical approximation. The approach used relies on the replacement of the probabilistic neuronal activation function f that has sigmoidal shape by a Heaviside-type function. The theory is accompanied by an example illustrating the procedure of investigation of ring solutions of a neural field equation containing a typically used in the neuroscience community neuronal connectivity function that allows taking into account both excitatory and inhibitory interneuronal interactions. Similar to the case of bump solutions (i. e. stationary solutions of neural field equations, which correspond to the activated area in the neural field represented by the interior of some circle) at a high values of the neuronal activation threshold there coexist a broad ring and a narrow ring solutions that merge together at the critical value of the activation threshold, above which there are no ring solutions.

Conditions of negativity for the Green’s function of a two-point boundary value
problem
L_λ u≔u^((n) )-λ∫_0^l▒〖u(s) d_s r(x,s)=f(x), x∈[0,l], B^k (u)=α,〗
where B^k (u)=(u(0),…,u^((n-k-1) ) (0),u(l),-u^'(l) ,…,(-1)^((k-1) ) u^((k-1) ) (0) ), n≥3, 0<k<n, k is odd, are considered. The function r(x,s) is assumed to be non-decreasing in the second argument. A necessary and sufficient condition for the nonnegativity of the solution of this boundary value problem on the set E of functions satisfying the conditions
u(0)=⋯=u^((n-k-2) ) (0)=0, u(l)=⋯=u^((k-2) ) (l)=0,
u^((n-k-1) ) (0)≥0, u^((k-1) ) (l)≥0, f(x)≤0 is obtained. This condition lies in the subcriticality of boundary value problems with vector functionals B^(k-1) and B^(k+1). Let k be even and λ^k be the smallest positive value of λ for which the problem L_λ u=0, B^k u=0 has a nontrivial solution. Then the pair of conditions λ<λ^(k-1) and λ<λ^(k+1) is necessary and sufficient for positivity of the solution of the problem.

Authors: Azizah Laily Nur , Wardhani Puspa , Arwati Heny
Published: January 2022

Introduction: Malaria is one of global health problems. Splenomegaly is one of malaria symptoms. Antimalarial drug resistance had been reported. Alternative treatment is by using traditional medicinal plants such as kelakai (Stenochlaena palustris). Kelakai contains alkaloid and flavonoid which had been reported to have antimalarial activity. The aim of this study was to discover antimalarial activity of ethanol extract of kelakai leaves to parasitemia and splenomegaly of Plasmodium berghei ANKA in infected BALB/c mice.Methods: This study was based on a modified Peter test using BALB/c mice infected with P. berghei ANKA treated with ethanol extract of kelakai leaves, with chloroquine diphosphate as a positive control. The negative control was P. berghei ANKA infected mice without any additional treatment. Administration of ethanol extract of kelakai leaves was performed for 4 days with a serial doses of 100, 10, and 1 mg/kg body weight. The positive control was given chloroquine diphosphate 20 mg/kg body weight. Parasitemia was observed daily prior to the calculation of the percentage of parasite growth and parasite growth inhibition. At the end of the test, the mice were sacrificed and spleens were isolated to measure their sizes. Probit analysis was performed to obtain ED50 to find the effect of extract in parasite killing by 50%. Spearman test was performed to analyze the correlation of doses of extract and splenomegaly.Results: Parasitemia growth inhibition was directly proportional to the dose. Higher parasitemia inhibition was obtained at higher doses and vice versa. Result of probit analysis showed an ED50 was 77.05 mg/kg body weight. Statistical analysis resulted in insignificant correlation between doses and splenomegaly p = 1.0 (significancy < 0.05).Conclusion: Ethanol extract of kelakai leaves possessed good antimalarial activity and there was no correlation between extract doses and splenomegaly in Plasmodium berghei ANKA-infected mice.

Published: January 2022

Introduction: Lack of sleep duration is one of the risk factors that cause excess body mass index (BMI). One of the mechanisms are by regulating an increase in appetite and reducing the energy used. This study aimed to identify the relationship between sleep duration and excess BMI in young adults.Methods: This descriptive-analytic observational study with cross-sectional design was conducted on 70 respondents aged 18-25 years old. The primary outcomes measured were sleep duration and BMI. Sleep duration was grouped as <7 hours (short sleepers), and ≥7 hours. BMI was classified as 18.5-22.9 as normal, and ≥23 as excess BMI (including overweight and obesity) according to Asia-Pacific classification. Data were analyzed using SPSS 21 software.Results: The study showed that the prevalence of excess BMI was higher in respondents with sleep deprivation (<7 hours) of 67% compared to respondents with enough sleep of 33%. The average sleep duration was 42 minutes shorter on respondents with excess BMI with an average of 6.1 hours and 6.8 hours on normal-weight respondents. According to the results of the study, there was a significant relationship between sleep duration and excess BMI (p < 0.05).Conclusion: The study revealed that sleep duration was related with excess BMI in young adults.

Published: January 2022

Introduction: Cataract is an eye lens opacification which prevents clear vision. It is the leading cause of blindness and vision impairment worldwide, including Indonesia. It can also be occurred in children that leads to a major cause of childhood blindness. The prevalence of childhood cataract ranges from 3 to 6 per 10,000 children. The main treatment for cataract is surgery, although pediatric cataract surgery has several complications. One of the most severe complication is glaucoma due to increased intraocular pressure (IOP). This study aimed to determine pre- and post-operative IOP in pediatric cataract surgery.Methods: This was a cross-sectional observational analytic study. Secondary data were collected from medical records of Department of Ophthalmology, Dr. Soetomo General Hospital Surabaya from January 2017 to August 2019. Age, gender, pre- and post-operative IOP, and intraocular lens implantation data were taken. Calculation was performed using the Saphiro-Wilk for data less than 50 samples.

Introduction: Tuberculosis is one of ten leading causes of death worldwide, including Indonesia. Indonesia is one of seven countries that causes 64% deaths due to tuberculosis. Tuberculosis is caused by Mycobacterium tuberculosis through droplet nuclei in the air. It can occur to any group age, including children and adolescent, if there is a contact history of people with tuberculosis infection. In 2016, one million children had tuberculosis and around 250,000 children died because of tuberculosis. This study aimed to know the profile of tuberculosis in children and adolescent at Dr. Soetomo General Hospital Surabaya.Methods: This was a descriptive study using retrospective approach. Sample of this study was collected from electronic medical record provided by Dr. Soetomo General Hospital Surabaya using statistic formula of single sample for estimated population proportions of children and adolescent with tuberculosis from 2013-2017, with total samples of 149 people.Results: There were 149 samples of children and adolescent patients with tuberculosis. Most of the children were mostly 0-4 years old and 57% were female. 84% of the children had been immunized with BCG and classified as moderate, and 35% were under nutritional status. This study showed that 67% of the children in household contacts of adult tuberculosis patients also had tuberculosis. The most frequent symptoms of tuberculosis in children and adolescent were fever (72%) and cough (80%).Conclusion: Tuberculosis in children and adolescent is more likely to occur in children than adolescent, especially children within group age of 0-4 years old. The number of pulmonary tuberculosis in children and adolescent are higher than extrapulmonary tuberculosis.

Published: January 2022

Shallow bathymetry inversion algorithms have long been applied in various types of remote sensing imagery with relative success. However, this approach requires that imagery with increased radiometric resolution in the visible spectrum is available. The recent developments in drones and camera sensors allow for testing current inversion techniques on new types of datasets. This study explores the bathymetric mapping capabilities of fused RGB and multispectral imagery, as an alternative to costly hyperspectral sensors. Combining drone-based RGB and multispectral imagery into a single cube dataset, provides the necessary radiometric detail for shallow bathymetry inversion applications. This technique is based on commercial and open-source software and does not require input of reference depth measurements in contrast to other approaches. The robustness of this method was tested on three different coastal sites with contrasting seafloor types. The use of suitable end-member spectra which are representative of the seafloor types of the study area and the sun zenith angle are important parameters in model tuning. The results of this study show good correlation (R2>0.7) and less than half a meter error when they are compared with sonar depth data. Consequently, integration of various drone-based imagery may be applied for producing centimetre resolution bathymetry maps at low cost for small-scale shallow areas.
Dysbiosis in Alzheimer’s Disease Might be Triggered by Certain Classes of Antibiotics with Time-lapse: New Insights in the Pathogenesis?
Authors: Ternák Gábor , Németh Márton , Rozanovic Martin , Bogár Lajos
Published: January 2022

Background and objectives: Alzheimer's disease (AD) is a progressive neurodegenerative illness, responsible for 60-70% of all dementias, affecting over 50 million people worldwide, and nearly 11 million in European countries. Several putative factors are identified in the literature as causative agents or risk factors for the development of AD. The amyloid cascade hypothesis has been the main hypothesis about the pathophysiology of AD for decades. Recent studies raised the possible role of dysbiosis in the development of AD which prevents memory loss. The amyloid-β (Aβ) deposition might be considered as an inflammatory reaction to certain molecular products arising from the altered microbiome. Based on the above observations, it has been suspected, that antibiotic consumption patterns of different antibiotic classes might be associated with the prevalence of AD in European countries. Methods: Antibiotic consumption (ECDC) for 1997-2007, 2008-2018, and as the whole 1997-2018 period, have been compared to the AD prevalence for 2018 expressed in percentage of the population and statistically analyzed by Pearson calculation. Results: A significant positive correlation has been found between the AD prevalence (2018) and the average quinolone consumption for the year 1997-2007 (p: 0.044). A similar association was not observed for the entire 22 years (1997-2018) of the average quinolone consumption, and the years 2008-18, indicating 10-20 years of time-lapse between the antibiotic exposure and the development of AD. The ratio of broad-spectrum and narrow-spectrum antibiotics (B/N) estimated in the ECDC database for the years of 2008-2018 showed a strong positive association with AD prevalence (2018) (p: 0.026) and a positive correlation tendency for the entire 22 years 1997-2018 (p: 0.063), but none for the years 1997-2007 (p: 0.241). Broad-spectrum, beta-lactamase sensitive penicillin (J01CA) consumption showed a positive (non-significant) correlation with the prevalence of AD for the years 2008-2018 (p:0.080).Discussion: Our study indicated the possible sequential role of certain classes of antibiotics in the development of dysbiosis leading to amyloid deposits of AD, which strengthen the possible role of different mediator molecules (short-chain fatty acids, lipopolysaccharides, etc.) produced by the altered microbiome in the development of AD.
Optimization, Modelling and Analysis of Air-Cooled Battery Thermal Management System for Electric Vehicles
Authors: Muddasar Muhammad
Published: January 2022

Electric Vehicles (EVs) are the need of the hour due to growing climate change problems linked with the transportation sector. Battery Thermal Management System (BTMS), which is accountable for certifying safety and performance of lithium-ion batteries (LiB), is the most vital part of an EV. LiB has auspicious gravimetric energy density but the heat generation due to chemical reactions inside a LiB during charging and discharging causes temperature rise which has a direct effect on LiB performance and safety. This study specifically focuses on aircooled BTMS, defines different types of air-cooled BTMS (active and Passive), discusses limitations associated with air-cooled BTMS, and investigates different optimization techniques and parameters to improve performance of air-cooled BTMS. Maintaining temperature within optimum range and uniform temperature distribution between cells of a battery pack are the major design parameters for improving the performance and efficiency of air-cooled BTMS. Various optimization techniques including cell arrangement with a battery pack, air-flow channel optimization, and air inlet/outlet position variations are discussed and each technique is thoroughly reviewed. Finally, it’s noted that passive air-cooled BTMS is not that effective for long-distance vehicles so most researchers shifted their focus toward active air-cooled BTMS. Active air-cooled BTMS requires a lot of power for effective performance. Lastly, the most recent field of air-cooled BTMS technology which is Air-Hybrid BTMS is discussed and declared a very promising solution for overcoming major limitations associated with air-cooled BTMS.

Published: January 2022

Changes in food preferences after bariatric surgery may alter its effectiveness as a treatment for obesity. We aimed to compare food reward for a comprehensive variety of food categories between patients who received a sleeve gastrectomy (SG) or a Roux-en-Y gastric bypass (RYGB) and to explore whether food reward differs according to weight loss. In this cross-sectional exploratory study, food reward was assessed using the Leeds Food Preference Questionnaire (LFPQ). We assessed liking and wanting of eleven food categories. Comparisons were done regarding type of surgery and Total Weight Loss (TWL; based on tercile distribution). Fifty-six patients (30 SG and 26 RYGB) were included (women: 70%; age: 44.0 (11.1) y). Regarding the type of surgery, scores were not significantly different between SG and RYGB, except for ‘non-dairy products – without color’ explicit liking (p = 0.04). Regarding TWL outcomes, explicit liking, explicit wanting and implicit wanting, scores were significantly higher for Good responders than Low responders for ‘No meat – High fat’ (post-hoc corrected p-value: 0.04, 0.03 and 0.04, respectively). Together, our results failed to identify major differences in liking and wanting regarding the type of surgery and tended to indicate that higher weight loss might be related to a higher reward for high protein-content food. Rather to focus only on palatable foods, future studies should also consider a broader range of food items, including protein reward.
Ducted Wind Turbine in Generating Set Air Flow
Authors: Anzanello Ivan
Published: January 2022

The growing need to use renewable sources and the current difficulty in spreading the electricity grid in a widespread manner raise the question of how to respond to the need for more electricity immediately. The idea behind this study is to power a horizontal axis wind turbine with the air flow generated for cooling a stationary internal combustion engine. The power extracted from this solution is significantly lower than that of the internal combustion engine (about 0.3%) and could be advantageous only in limited contexts. Installation costs are limited because many elements deriving from wind variability can be removed or simplified.
Optimization of a Bearing Fault Diagnosis Method Based on Convolutional Neural Network and Wavelet Packet Transform by Simulated Annealing
Authors: He Feng , Ye Qing
Published: January 2022

Bearings are widely used in various types of electrical machinery and equipment. As their core components, failures will often cause serious consequences . At present, most methods of parameter adjustment are still manual adjustment of parameters. This adjustment method is susceptible to prior knowledge and easy to fall into the local optimal solution, failing to obtain the global optimal solution and requires a lot of resources.Therefore, this paper proposes a new method of bearing fault diagnosis based on wavelet packet transform and convolutional neural network optimized by simulated annealing algorithm.The experimental results show that the method proposed in this paper has a more accurate effect in feature extraction and fault classification compared with traditional bearing fault diagnosis methods. At the same time, compared with the traditional artificial neural network parameter adjustment, this paper introduces the simulated annealing algorithm to automatically adjust the parameters of the neural network, thereby obtaining an adaptive bearing fault diagnosis method. To verify the effectiveness of the method, the Case Western Reserve University bearing database was used for testing, and the traditional intelligent bearing fault diagnosis method was compared. The results show that the method proposed in this paper has good results in bearing fault diagnosis. Provides a new way of thinking in the field of bearing fault diagnosis in parameter adjustment and fault classification algorithms
Genus-Physiognomy-Ecosystem Map with 88 Legends Produced at 10m-resolution First-time in a Country Scale through Machine Learning of Multi-temporal Satellite Images
Authors: Sharma Ram C. , Hara Keitarou
Published: January 2022

This research introduces Genus-Physiognomy-Ecosystem (GPE) mapping at a prefecture level through machine learning of multi-spectral and multi-temporal satellite images at 10m spatial resolution, and later integration of prefecture wise maps into country scale for dealing with 88 GPE types to be classified from a large size of training data involved in the research effectively. This research was made possible by harnessing entire archives of Level-2A product, Bottom of Atmosphere reflectance images collected by MultiSpectral Instruments onboard a constellation of two polar-orbiting Sentinel-2 mission satellites. The satellite images were pre-processed for cloud masking and monthly median composite images consisting of 10 multi-spectral bands and 7 spectral indexes were generated. The ground truth labels were extracted from extant vegetation survey maps by implementing systematic stratified sampling approach and noisy labels were dropped out for preparing a reliable ground truth database. Graphics Processing Unit (GPU) implementation of Gradient Boosting Decision Trees (GBDT) classifier was employed for classification of 88 GPE types from 204 satellite features. The classification accuracy computed with 25% test data varied from 65-81% in terms of F1-score across 48 prefectural regions. This research produced seamless maps of 88 GPE types first time at a country scale with an average 72% F1-score.

Entrepreneurship is a current term that seeks to address problems of economic and social nature, because it motivates students to take initiatives in creating their own businesses not only as individual well-being but social impact, providing employment opportunities to others. Many entrepreneurs have emerged from perso- nal motivations that have led them to implement entrepreneurship as a solution strategy and mee- ting their needs, it is essential to understand that entrepreneurship is not a privilege, it ́s not innate to human beings; rather it contemplates a set of skills that are learned throughout life. According to the regulations with the promulgation of Law 1014 of 2006 secondary education should be aimed at preparing young people from her school for entrepreneurship and business management by adopting labor skills to do so productive and able to seek independent income to improve their quality life and thus portend economic growth. It is important to make educational proposals that address learning needs in current contexts where training is comprehensive and does not seek only to impart knowledge but also provide tools that contribute to the formation of competitive students and this helps them to function in the workplace. That is why, a curriculum design and implementation workshops in the vocational middle of the Educational Institution Gabriel Betancourt to contribute and strengthen entrepreneurship is proposed.
The Effect of Number of Factors and Data on Monthly Weather Classification Performance Using Artificial Neural Networks

Published: January 2022

Current weather-related research only focuses on weather prediction based on raw data and the factors used are generally 4 factors: average temperature, solar radiation, air pressure, and wind. In this research, monthly weather prediction is done using 5 factors where the additional factor used is rainfall in the previous time. In contrast to previous prediction research, the prediction process carried out in this study emphasizes the modeling of training data according to the desired prediction model.. These two things distinguish this research from previous studies. The prediction model used in this study is a classification-based prediction model that is the Artificial Neural Network (ANN) method combined with the backpropagation algorithm for calculating the weight of the ANN network. The data used are meteorological data from 2010 to 2018 in the Bogor area, where data from 2010 to 2016 are used as training data, and data from 2017 to 2018 are used as test data. The results of this study indicate that the design of the model with the use of data for 6 years with feature data of 5 factors has an accuracy rate of 83.33%.

Portfólios de ensino têm sido apontados como ferramentas formativas e reflexivas nos diversos graus de ensino. O objetivo deste ensaio é relatar uma experiência em desenvolver um portfólio interdisciplinar como dispositivo pedagógico para o exercício da narratividade de um plano de aula, para a disciplina de imunologia do curso superior de Medicina Veterinária (MV), do Instituto Federal Catarinense (IFC) Campus Concórdia. O portfólio foi desenvolvido para dois encontros virtuais como metodologia ativa para a disciplina de imunologia em tempos de pandemia. Essa experiência foi vivida por professores1,2 em dois ambientes distintos, Florianópolis e Concórdia, com as seguintes informações: a) descrição do curso superior, da disciplina, do conteúdo da aula, do perfil do discente, do perfil do docente convidado, do plano de aula (PA) e do planejamento do PA, da reflexão do aluno e professor. Durante o tempo em que foi aplicado o portfólio analisou-se a importância do uso dessa ferramenta como amostra de evidências das habilidades, atitudes e/ou conhecimentos obtidos pelos acadêmicos. A avaliação qualitativa dos alunos foi a etapa final do processo e compreendeu em atividades lúdicas por interfaces de softwares e questionários de respostas investigativas composta por questões objetivas e dissertativas com autoavaliações. O aprendizado colaborativo favoreceu o desenvolvimento de competências interpessoais como a comunicação, trabalho em equipe, persuasão, flexibilidade, empatia, espírito de colaboração e responsabilidade.  O atual desafio educacional trouxe a oportunidade de pensar em soluções didáticas inovadoras usando apenas recursos de casa ou do meio digital. O trabalho demonstrou a existência de prática relevante em gestão de portfólio, suportado pela teoria da disciplina, embora limitado pela aplicação em somente duas aulas e não ao semestre completo.

A agricultura camponesa é de suma importância para o estado do Amazonas, bem como para o município de Tefé, uma vez que é produtora de parte da base alimentar da população. Apesar de sua relevância, muitas vezes a prática da agricultura gera impactos relevantes à saúde dos trabalhadores que executam essa atividade devido à precariedade das condições de trabalho. Este trabalho teve como enfoque o ambiente e saúde dos camponeses nas comunidades do Novo Paraíso e Bom Jesus na estrada da Emade no município de Tefé-Amazonas e objetivou compreender as principais doenças e agravos relacionados ao trabalho dos camponeses. Partiu-se da pesquisa bibliográfica, discutindo os diferentes enfoques sobre a temática, posteriormente, utilizou-se dos procedimentos metodológicos como: coleta de dados secundários em instituições municipais e pesquisa de campo com aplicação de questionários. A pesquisa evidenciou que as precárias condições de trabalho afetam direta e indiretamente a saúde dos camponeses, além do fator potencializador como o desconforto térmico devido as extensas jornadas de exposição à radiação solar, temperaturas e umidade elevadas. Assim acende um alerta para a ampliação do uso de equipamentos de proteção individual, essenciais para prevenir acidentes e adoecimentos mediante a prática de trabalho no campo, além da relevância do estudo para impulsionar políticas públicas voltadas a atenção da saúde desses trabalhadores.
