Authors: Kukeyeva Aigerim , Abdrakhmanov Talgat , Yeszhanova Gulzhan , Bakisheva Zhanar , Kemeshov Zhomart
Published: September 2023

Background:
Mastitis is a disease of productive cows, widespread throughout the world, and characterized by significant economic damage to the dairy industry. The subclinical form of this disease is aggravated by additional difficulties with its diagnosis and the lack of clear treatment protocols.
Aim:
Therefore, the study of the effectiveness of diagnostic studies and the search for new methods of treatment of latent forms of mastitis is an important direction in scientific research in countries with developed dairy cattle breeding.
Methods:
Studies conducted on the number of dairy cows of the production cooperative “Izhevsky” of the Akmola region of the Republic of Kazakhstan showed that when using rapid tests Kenotest, Somatest, Mastidine test, and Wideside test, the same results were obtained when a disease was detected in cows. The effectiveness of the tests was at the level of 60-62% when using the settling sample as a control. Medical procedures were carried out using the Aquaton-2 microwave radiation apparatus and a homeopathic preparation. When using physiotherapy with microwave radiation, a decrease in the level of microbial contamination of milk from the treated part of the udder by 1.5-5 times was observed.
Results:
Biologically active substances of plant origin in the homeopathic preparation, due to the immunostimulating effect, made it possible to increase the level of γ-globulins in the blood serum of sick animals during the application.
Conclusion:
The complex use of both methods in the treatment of animals with a subclinical form of mastitis made it possible to reduce the level of somatic cells in the milk of the affected udder lobe to a level that cannot be determined using Kenotest in 4-6 days, which is 2-4 days faster than using these methods separately.

Authors: Buitrago Deisy , eda Diana , Forero Julio , Medellin Martin
Published: September 2023

Background:
Enzootic Bovine Leukosis (EBL) is a lymphoproliferative disorder caused by Bovine Leukemia Virus (BLV), a virus of the Retroviridae family. The infection is distributed worldwide, and a high percentage of animals infected by the BLV are asymptomatic and act as carriers of the virus in many cattle populations.
Aim:
To identify the risk factors associated with EBL in municipalities of Boyacá and Cundinamarca (Colombia).
Methods:
A simple descriptive cross-sectional study with random sampling was conducted. A total of 1140 blood samples were taken from cattle (females and males) from the municipalities of Chiquinquirá, Ubaté and San Miguel de Sema, of different breeds and age groups. The samples were processed using the commercial ELISA SERELISA® BLV Ab Mono Blocking kit (sensitivity 97%, specificity 98%). The data were processed with the statistical programs WinEpi and Epi Info® version 7.2.4.0, estimating the prevalence ratio, implementing Chi-square test (p≤0.05) and logistic regression.
Results:
A true prevalence (TP) and apparent prevalence (AP) of 23.61 and 22.7% in Ubaté, 19.22 and 18.1% in Chiquinquirá and 15.61 and 14.3% in San Miguel de Sema, respectively, were established. Bovines 2-4 years old were the most prevalent in Ubaté and Chiquinquirá (37.5% and 21.21% respectively), while in San Miguel de Sema individuals >4 years had the highest percentage of antibodies (18.3%). The Holstein breed had a higher prevalence in Ubaté and San Miguel de Sema (26.02% and 19.67%), and crossbreeds were more BLV-seroprevalence in Chiquinquirá (20.20%). In Ubaté, re-use of needles was identified as risk factors, contaminated blood in needle is considered one of the main routes of transmission. On the other hand, manual milking was identified as risk factors in San Miguel de Sema.
Conclusion:
The non-implementation of an individual needle per animal in Ubaté; the Holstein breed and manual milking in San Miguel de Sema were identified as risk factors for the presence of antibodies against the disease. EBL prevention and control plans should be established that focus on the implementation of management and sanitary practices based on herd biosecurity.

Published: September 2023

Background:
Staphylococcus aureus is a typical pathogenic agent causes several morbidities and mortalities which variable largely following the severity of bacteria and activity of host immunity.
Aim:
Isolation of S. aureus from different cattle infections, molecular detection of nuc gene in positive S. aureus isolates and identification the effectiveness of phagocytic activity.
Methods:
Totally, 100 cattle with various infections (25 wounds, 25 abscesses, 25 nasal discharge, and 25 ear swaps) were selected and subjected for collection of swabs under controlled conditions. All collected samples were cultured on Mannitol salt agar (MSA) and assessed by the biochemical tests. Targeting the nuc gene, all study MSA positive isolates were examined molecularly by conventional polymerase chain reaction (PCR), and then subjected for antibiotic susceptibility test. Jugular venous blood was collected from all infected animals in addition to 20 healthy cattle that selected as a control group to estimate the phagocytic activity of S. aureus isolates.
Results:
The findings of MSA culture revealed a totally 80 positive samples to S. aureus as 23, 21, 20, and 16 positive isolates for nasal discharge, abscess, wound and ear swab, respectively; based on its morphology, cultural trait, and biochemical test. Subsequently, PCR assaying of MSA positive isolates was demonstrated an overall 59 positive samples as 14, 16, 12 and 17 positive isolates for nasal discharge, abscess, wound and ear swab, respectively. Antibiotic susceptibility testing of S. aureus positive PCR isolates reported a significant high sensitivity to chloramphenicol and vancomycin, and a high resistance to penicillin. Finally, there was a considerable decline in phagocytic activity in particular 2 weeks post infection as a result of bacterial invasion.
Conclusion:
This study shows a high prevalence of S. aureus in cattle infections, and protocol includes regular screening of cattle infection and suitable therapy based on antibacterial susceptibility test is of great importance in long-term control of pathogen. However, additional molecular studies targeting other genes of S. aureus and the role of immune markers in different infections should be aimed

Published: September 2023

Background: Infertility is a worldwide problem affecting about 10-15% of married couples and has social, economic and psychological implications1. A significant number of couples will require assisted reproduction following failure of common treatment options. Undergraduates form a rich source of potential gamete donors and it is imperative to assess their knowledge, attitude and willingness to participate in the expanding gamete donor programs in a developing country like Nigeria.

Objectives: This study aimed to assess the knowledge and attitude of participants about assisted reproduction and to further evaluate their willingness to donate gametes for assisted conception or act as surrogates.

Methodology: This was a cross-sectional descriptive study of 1150 participants consisting of 511 male students and 639 female students of the University of Ibadan. Participants were selected by simple random sampling technique. A semistructured, self-administered questionnaire was used to obtain information on sociodemographic characteristics, knowledge, attitude and willingness to participate in gamete donor programs. Participation was voluntary and data obtained was treated with utmost confidentiality. Data was analyzed using the Statistical Package for Social Sciences (IBM SPSS, New York) version 22.Descriptive statistics were generated, and the results summarized with the aid of a bar chart and frequency tables.

Results: Eight seven percent of the respondents had good knowledge of Assisted Reproductive Techniques (ART) and the most common source of awareness was the media (63.3%). More respondents were aware of sperm donation (75.5%)compared to egg donation (61.9%). Ninety percent of the participants were correctly able to identify the places where ART could be practiced in Nigeria.Most of the respondents (81.5%) supported ART services and the most common reason for not supporting was due to ethical considerations (45.1%). Only about 54.9% were willing to participate in gamete donor programs. Nine (0.8%) female respondents had previously participated in egg (oocyte) donation while none of the male respondents had ever donated sperm. About threequarters of the respondents demonstrated good knowledge about the practice of surrogacy.

Building Buy-in: A Qualitative Study Seeking to Understand Stakeholder
Perceptions of a University Extension System Through the Lens of External Branding
Authors: Zagonel Anissa M. , Baker Lauri , Telg Ricky
Published: September 2023

A brand is an organization’s link to its audiences. When
the audience is asked to participate in building a brand culture, they are more likely
to hold a favorable attitude toward the brand and be loyal to the brand long term. The
purpose of this study was to understand the UF/IFAS Extension brand’s image from the
perspective of the brand’s stakeholders, specifically focusing on brand awareness,
audience groups, and potential future obstacles for the brand. A series of six online
focus groups were conducted during the spring/summer of 2021 using Zoom. Major themes
identified were a public knowledge gap related to Extension and agriculture, the focus
of UF/IFAS Extension was (too) broad, agriculture was not valued in the state, and a
disconnect existed between the public and Extension and agriculture. Results confirm the
complexity of branding an organization when efforts need to highlight products, such as
programming, and services, such as soil sampling, while also embodying unseen values and
culture associated with the brand. Results from this study can be used to improve the
UF/IFAS Extension brand through increased marketing, determining appropriate focus and
communicating that focus, and continuing to engage stakeholders in the co-creation of
branding.

Published: September 2023

Programming which promotes healthy aging may be lacking in
states where nutrition and health interventions are directed earlier in life. Due to
Maryland’s increasing aging population, a team of 10 University of Maryland Extension
Family and Consumer Sciences educators received permission to adapt and implement the
Iowa Department of Public Health’s, in partnership with the Iowa Department of Human
Services and Department on Aging, Fresh Conversations program to fit the needs of
Maryland’s older adults. The purpose of this manuscript is not to discuss research
findings but rather to share our challenges, successes, and recommendations for adapting
and implementing another state’s multi-session program to meet the needs of individual
states’ communities. Specifically, we discovered communicating with partnering sites,
offering food tastings, accommodating various food cultures/traditions, following the
original program design, and efficiently collecting data or programmatic form responses
needed careful consideration. Despite the challenges we encountered, we expanded our
national and state partnerships; reached 2,836 educational contacts across the state;
and developed a detailed planning, implementation, and evaluation protocol and training,
which is being used as a template for other statewide program efforts.

Authors: Johnson Haley M. , Hall Kelsey L , Scow Benjamin
Published: September 2023

This study compared four horseless and seven traditional
horse participants from Washington County 4-H in Utah for horse knowledge gained and for
the development of 10 life skills from Hendricks’s Targeting Life Skills Model:
leadership, teamwork, self-responsibility, personal safety, problem-solving,
decision-making, critical thinking, goal setting, communication, and concern for others.
This study’s mixed methods design employed interviews to learn about life skill
development and quantitative data from a 20-item horse knowledge quiz and demographic
survey. The traditional horse youth showed greater development of leadership,
self-responsibility, decision-making, goal setting, and communication than the horseless
youth. Roughly half of the participants in both groups experienced having concern for
others in their program, but both programs lacked the development of critical thinking
and problem-solving. As for horse knowledge, traditional horse participant scores were
15% to 40% better than horseless participants. The horseless participants lacked
knowledge on the parts of a western saddle and horsemanship. Recommendations for future
research include observational research in addition to participants’ self-perceived
data, perspectives of the adult leaders, and pre-post test data to track the growth of
life skills and horse knowledge in horseless and traditional horse participants.
Explicando pasados y actuando presentes en época del coronavirus
Authors: Fernández Poncela Anna María
Published: September 2023

Este texto es un acercamiento a miradas cotidianas y respuestas personales y colectivas en torno al coronavirus, esto es, opiniones y acciones, que se expresan y relatan entre creencias, emociones y comportamientos. Describir, comprender y explicar las concepciones y vivencias que entrecruzan sentimientos e interpretaciones del origen de la pandemia en el pasado reciente y de actuaciones y opiniones del presente, desde el ámbito individual, en ocasiones ampliado al entorno, familia y sociedad. Esto se hace a partir de narraciones de entrevistas de un grupo de personas en la Ciudad de México a principios de 2021. Se presentan sus ideas sobre el inicio de la pandemia centradas en la zoonosis, un laboratorio y el contagio; afirman la gravedad de la situación y las responsabilidades de nadie y de todos, y de los que no cumplen las medidas, especialmente. También reiteran la presente necesidad de mantener y respetar las medidas sanitarias e incluso hacerlas más estrictas y sancionadas, pues se las considera necesarias, y a quien no las acata, el verdadero problema. El panorama general es de aceptación a la prolongación de la situación y a la venida de más pandemias, de adaptación y una actitud positiva. Finalmente, es posible interpretar un imaginario social instituido, representaciones sociales compartidas, y una conformidad colectiva importante que crea y recrea un consenso social, un modelo hegemónico socio sanitario, político y cultural global, que proviene de la obediencia a la autoridad y que se consolida con el pensamiento de grupo, reforzándose incluso con el señalamiento del otro incumplidor como chivo expiatorio.
Capitalismo, conflicto social y acción sociopolítica: coordenadas para una propuesta marxista
Authors: Penaglia Vásquez Francesco Emmanuel
Published: September 2023

El marxismo tuvo un extenso desarrollo durante los siglos XIX y XX en el estudio de la acción sociopolítica y el conflicto social. Sin embargo, desde mediados del siglo XX, su uso teórico fue siendo desplazado por el estructural funcionalismo, los enfoques estratégicos y las teorías culturales. Esto, fue acompañado por el declive de tradiciones holistas y un giro hacia lo discursivo y la agencia, provocándose un paulatino abandono en el estudio de la relación entre capitalismo, conflicto social y acción sociopolítica. El presente artículo postula que el marxismo tiene vigencia teórico-analítica para el estudio del conflicto y la acción sociopolítica, sin embargo, tanto su amplitud y diversidad de tradiciones, como las dificultades para sistematizar y operacionalizar un marco analítico, han limitado su aplicación y uso. Desde allí se propone una revisión teórico-analítica de las principales coordenadas del debate marxista del siglo XX-XXI identificando nudos críticos para una agenda de investigación.

This research was developed based on the problem of waste from the coconut export industry and the current trend of water pollution. This research aims to study methylene blue adsorption by using coconut shell charcoal prepared from clay kilns. The study of adsorption isotherms in batch experiments showed that the coconut shell charcoal was fitted well with Langmuir adsorption isotherms with a capacity of 36.49 mg g–1 for particle size in the range of 53 – 74 mm. Through the determination of the surface area of methylene blue adsorption, coconut shell charcoal in the range of 53 – 74 micrometers had the highest surface area of 65.95 m2 g–1. Coconut shell charcoal was used to study the adsorption of ferrous metal solution at the initial concentration of 15 mg l–1. It was found that 0.25 g of coconut shell charcoal had the highest absorption capacity of 17.29% of the ferrous metal solution.
Numerical evaluation of an external environment effectiveness to the surface plasmon mode in Au slot waveguide for design the sensor simulation
Authors: Racknoi Pattrapong
Published: September 2023

The effective permittivity of gold thin films with an external thin dielectric layer on the top and core of the slot waveguide was evaluated as an effective compound semi-metal layer of the surface plasmonic polariton slot waveguide that will vary due to some environmental factors. By uses simple parallel and series permittivity of compound material, this value need for the computation of the effective propagating vector βsp. This takes for a sensor model designing which the external environment effectiveness was changed by the surface plasmonic mode in its slot waveguide.   So the resonance length and grating period are evaluated for the sensor model in the first. Further, the propagation of the SPP surface wave mode along the interface between the compound cladding and Si dielectric waveguide is computed, while the effective refractive index of the compound cladding of the slot waveguide is increased from 1 − 1.50. The computation results showed that the TM0 mode power transfer and propagation length seem to vary with this effective refractive index of the compound cladding on the surface plasmonic polariton waveguide. The 140 nm gap width and 3.70 mm long waveguide is also simulated by the finite different time domain method in the optiwave program, where the TM0 mode transition output is corrected, while the refractive index of the environment layer is changed. The results of the simulation showed good agreement with the computation in that the TM0 mode depends on the external refractive of index and input wavelength. This result shows that loss peak ships vary with the external refractive index thin film layer and input wavelength. Thus, they seem to be useful for sensor applications such as the solution concentration analytic.

Published: September 2023

In this work, Ni-doped CuCo2O4 (Cu1–xNixCo2O4, x=0, 0.20, 0.40, 0.60 and 0.80) catalysts wer synthesized by polymerized complex and electrodeposition methods on flexible carbon fiber substrates for the oxygen evolution reaction (OER) in alkaline solution. The crystallinity and surface morphology of the catalysts were characterized by X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM).The XRD results showed that the crystallinity corresponded to CuCo2O4 phases. The OER revealed that Cu0.40Ni0.60Co2O4 had higher activity for OER with a low overpotential of 256 mV at a current density of 10 mA cm–2, which was better than CuCo2O4 (451 mV). The results suggest that the presence of Ni2+ ions in spinel CuCo2O4 exhibited superior electrocatalytic activity towards OER with lower overpotential, and higher current density than CuCo2O4.

Published: August 2023

O estado de Rondônia implantou o Ensino Médio Mediado por Tecnologia (EMMT) em 2016. O modelo foi inspirado no projeto de Educação Mediada que estava em funcionamento na época, no estado do Amazonas. Neste modelo de ensino, os alunos se dirigem a uma escola, onde recebem aulas ao vivo, via satélite, ministradas por um professor que está em estúdio. Os alunos acompanham essas aulas com outro professor em diversas escolas espalhadas por todo o estado. Com a conclusão das primeiras turmas de EMMT na educação básica, cabe investigar as condições de infraestrutura e tecnologia disponibilizada para os egressos. Para o lócus da pesquisa foi escolhido o distrito de Calama, em Porto Velho, uma comunidade ribeirinha de difícil acesso na Amazônia. A abordagem da pesquisa é qualitativa, baseada em entrevistas com questionário semiestruturados, os quais foram analisados por meio da análise do discurso de Bardin e da teoria da complexidade de Morin. Participaram oito egressos do ensino médio da escola General Osório, no distrito de Calama. Os resultados da pesquisa evidenciam que essa política pública, em lugares de difícil acesso, por meio das Tecnologias da Informação e Comunicação (TICs) na Educação enfrentou inúmeros desafios e que falta de infraestrutura causou grandes problemas no desenvolvimento das atividades dos professores e alunos.

O voluntariado corporativo tem um papel reconhecido e importante a desempenhar no alcance dos Objetivos de Desenvolvimento Sustentável (ODS) das Nações Unidas, entretanto, a literatura explorando o papel do voluntariado em relação aos ODS ainda é limitada. Com referência ao cooperativismo também há uma falta de estudos que investiguem como as práticas desempenhadas pelas cooperativas contribuem para a realização dos ODS. Por isso este artigo analisa como o voluntariado corporativo em uma cooperativa pode contribuir para a implementação dos ODS a partir das perspectivas dos voluntários. Para atingir este propósito foram realizados quatro focus group com voluntários, além da análise documental sobre as ações de voluntariado na cooperativa. A partir da análise de conteúdo das informações coletadas conclui-se que o voluntariado corporativo serve como estratégia para a cooperativa estar próxima da comunidade onde está inserida, e com isso praticar ativamente seus princípios e valores, colocando-se efetivamente como organização empresarial transformadora. A combinação dessas práticas de voluntariado com os ODS, seus objetivos e metas, fortalece as práticas que passam a ser orientadas por diretrizes globais com aplicabilidade local.

Buscar as evidências científicas disponíveis sobre a Visualização com Imagem Guiada em pacientes oncológicos no alívio dos efeitos adversos do tratamento quimioterápico e consequentemente a melhora da qualidade de vida relacionada à saúde. Trata-se de uma Revisão Integrativa com base nas seis etapas proposta por Mendes, Silveira e Galvão (2008). A questão norteadora foi baseada na estratégia PICO sendo: O relaxamento com visualização guiada em pacientes oncológicos alívio dos efeitos adversos do tratamento quimioterápico e consequentemente melhora a qualidade de vida relacionada à saúde? Foram utilizadas as fontes de dados BVS, SCOPUS, WEB OF SCIENCE e CINAHL. Como critérios de inclusão: Estudos primários que abordam a temática benefícios da visualização com imagem guiada, em pacientes adultos (maiores e igual a 18 anos), publicados no período de janeiro de 2017 a dezembro de 2022 nos idiomas, português, inglês e espanhol. Foram utilizados os descritores controlados: Imagens, psicoterapia; neoplasias; terapia de relaxamento; qualidade de vida; Tratamento farmacológico. Sete estudos (100%) resultaram no benefício da Visualização com Imagem Guiada na diminuição dos sintomas causados pela quimioterapia. Sendo que, quatro estudos (57,14%) mostram que a técnica diminui os sintomas, como náusea e vômitos, dois estudos (28,57%) mostram que reduz significativamente a dor, três estudos (42,86%), descrevem a redução dos níveis de depressão e ansiedade e elevação da auto-estima, que refletem principalmente na Qualidade de Vida Relacionado à Saúde. Ademais, de acordo com os níveis de evidência, cinco estudos (71,43%) apresentam nível II, um artigo (14,28%) nível de evidência V e um artigo (14,28%) com nível de evidência III. Os benefícios concedidos pela Visualização com Imagem Guiada contribuem para a assistência de enfermagem e para o paciente oncológico permitindo a aceitação e o enfrentamento da doença e do tratamento com maior qualidade de vida.

Em oposição ao ensino tradicionalista, que fundamenta suas ações em transmissão de informações e técnicas de memorização e repetição de conteúdo, limitando o aprendizado discente a decorar fórmulas e conceitos, sem nenhuma correlação com o cotidiano de cada agente envolvido no processo de ensino-aprendizagem, o presente trabalho de pesquisa tem por finalidade abordar a temática da aprendizagem significativa como metodologia de ensino que considere situações reais, vividas por cada estudante, como laboratório didático para o ensino de Física. Através de intervenções didáticas que prezem pela dialogicidade e a valorização dos conhecimentos prévios de cada estudante, foi trabalhado o ensino de circuitos elétricos com turmas da terceira séria do ensino médio. A escolha do assunto é justificada pelos inúmeros exemplos de circuitos elétricos passíveis de serem identificados no dia a dia discente, aproximando a Física da vivência diária das pessoas, sendo fundamental para melhor escolha e aproveitamento dos dispositivos elétricos e eletrônicos. Através da observação e dos diálogos realizados, foi possível identificar lacunas conceituais sobre corrente elétrica, como um fluxo de cargas elétricas e a diferenciação das associações de resistores, segundo suas funcionalidades, a partir da corrente e da tensão, e substituí-las por informações científicas trazidas pelo estudo da Física. A partir de uma metodologia dialogada e centrada no cotidiano discente, os resultados mostraram um perfil de maior motivação e curiosidade, além de proporcionar a construção de um vocabulário científico que descreva as situações da realidade sociocultural de cada estudante. Os resultados também permitiram observar uma maior valorização da aprendizagem em Física, aliada na interpretação da natureza e nas situações rotineiras dos nossos dias.
Edificando caminhos para a educação inclusiva: ações e reflexões sobre a inclusão escolar

O artigo apresenta um relato de experiência e um recorte da realidade vivenciada a partir do desenvolvimento de um projeto educacional inclusivo, intitulado de “EDIFICANDO CAMINHOS PARA A EDUCAÇÃO INCLUSIVA: INCLUIR É PARTICIPAR!” desenvolvido por duas professoras que atuam no Atendimento Educacional Especializado-AEE, em uma escola da rede pública no município de Santarém - Pará. A problemática foi identificada a partir dos acompanhamentos do AEE realizados em sala de aula, durante os quais foram observados os comportamentos e relações interpessoais entre alunos. Percebeu- se a fragilidade nas relações educacionais e sociais na sala de aula comum, quanto aos “pré-conceitos” estabelecidos aos alunos com deficiência, ocasionando atitudes de desrespeito e exclusão. Nesse viés, o objetivo do projeto foi desenvolver estratégias metodológicas inclusivas utilizadas em parceria colaborativa com o professor da sala de aula comum e gestão escolar, para estimular o “movimento de práticas inclusivas” entre todos os envolvidos no processo. Para obtenção dos dados foram realizadas observações e registros em diário de campo sobre os questionamentos e dúvidas dos alunos, que surgiram durante aplicabilidade do projeto, que foi desenvolvido através de palestras temáticas sobre a Inclusão Escolar: Direito e respeito à Diversidade, para dialogar com a problemática apresentada. Assim o material utilizado pautou-se em documentos legais, tais como: a Política Nacional de Educação Especial Inclusiva 2008, Decreto 7611/2011, que dispõe sobre o Atendimento Educacional Especializado – AEE, Lei Brasileira de Inclusão 2015 e pesquisadores, como: Mantoan (2003), Veiga – Neto e Lopes (2011), etc.; os quais corroboram com a necessidade de fortalecer práticas inclusivas para desenvolver o valor e respeito mútuo aos alunos público-alvo da Educação Especial, inseridos na sala de aula comum. Conclui-se que a partir da reflexão sobre as temáticas abordadas nas palestras e as inquietações apresentadas pelos alunos, face aos alunos inseridos, trouxe à tona a desordem conceptual sobre as ações de “in/exclusão” praticadas no contexto escolar. Com os resultados obtidos, percebeu-se maior interesse dos profissionais envolvidos e dos alunos de turma, em buscar mais conhecimentos sobre inclusão, valorização e respeito ao colega, passando a desenvolver práticas inclusivas nas atividades escolares e em suas relações interpessoais. A realidade vivenciada demonstra importância em proporcionar estratégias pedagógicas que possibilitem realizar ações inclusivas na escola regular com apoio e comprometimento dos envolvidos (professores e gestão escolar) como possibilidade de fortalecimento da inclusão escolar de fato e direito e a “Construção da Escola Inclusiva”.

The presence of foreign objects in pepper seeds is one of the things that affect the quality of pepper seeds. Farmers in Bangka sell pepper to pepper collectors. The collectors in this area still inspect the pepper using manual methods without the help of other tools, so there are still foreign objects such as dry leaves or pepper stalks. This method is often inefficient because the precision of each person is different. In this case, we propose to determine the quality of pepper based on the percentage of foreign objects automatically in accordance with the determination of pepper quality standards regulated in the national quality standard (SNI). The authors use YOLOv3 for object detection which is one of the fastest and most accurate object detection methods, outperforming other detection algorithms. However, YOLOv3 requires a heavy computer architecture. Therefore, YOLOv3-tiny, a lighter version of YOLOv3, can be a solution for smaller architectures. This study found that YOLOv3-tiny model has a reasonably high network performance value: precision value of 0.99, recall value above 70%, and F1 score above 80%. While determining the quality of pepper according to the standard quality of pepper (SNI) the value obtained must be below 2%. Then a comparison was made between the detection system and the manual calculation of objects. It was found that in the sample of 26 pepper seeds, the system detected 8.97 seconds faster than manual calculation.

Bacterial identification is an essential task in medical disciplines and food hygiene. The characteristics of bacteria can be examined under a microscope using culture techniques. However, traditional clinical laboratory culture methods require considerable work, primarily physical and manual effort. An automated process using deep learning technology has been widely used for increasing accuracy and decreasing working costs. In this paper, our research evaluates different types of existing deep CNN models for bacterial contamination classification when low-resource data are used. They are baseline CNN, GCNN, ResNet, and VGGNet. The performance of CNN models was also compared with the traditional machine learning method, including SIFT+SVM. The performance of the DIBaS dataset and our own collected dataset have been evaluated. The results show that VGGNet achieves the highest accuracy. In addition, data augmentation was performed to inflate the dataset. After fitting the model with augmented data, the results show that the accuracy increases significantly. This improvement is consistent in all models and both datasets.
