Published: September 2020

We review canine dietary supplements, in particular silymarin and its hepatoprotective properties. Dietary supplements should be considered complements to conventional drug treatments, helping to prevent health issues, such as nutritional deficiencies and organ dysfunctions. The market for veterinary supplements is growing rapidly. Pet owners are increasingly eager to provide their animals with the best care available. The rapidly growing market of supplements is an opportunity for both the industry and veterinarians, who can introduce new treatment protocols supported by dedicated dietary supplements. The liver is one organ that can be nutritionally supported in case of dysfunction. In dogs, hepatopathies may be primary or may be secondary to an underlying problem. Toxins, drugs, and neoplasia are reported among the causes of liver dysfunctions. There are several substances with proven liver-beneficial properties. One of these is silybin, a hepatoprotector extracted from Silybum marianum. Dietary supplementation with silybin seems a reasonable tool to support a core treatment for liver disease. Laboratory tests have additionally shown that silybin supplementation helps reduce liver damage. The literature indicates that silybin acts not only as an antioxidant, but also as an antifibrotic agent and a stimulator of cell regeneration. Due to its multidirectional action, it can effectively reduce liver damage, or help prevent it. Independent of the reason for its administration (prevention or therapy), it has been reported effective in laboratory animals, dogs, and humans. This was confirmed by an observational study performed at the University Center for Veterinary Medicine at Poznań University of Life Sciences. A total of 15 dogs with diagnosed liver conditions were supplemented with silybin for 30 days. Significant improvements were reported in the liver blood markers after the supplementation period. All things considered, silybin dietary supplementation is a noteworthy strategy in prevention and treatment of liver diseases in dogs.

Resumo

O estágio supervisionado é um momento singular no processo de formação docente, trata-se da fase em que o acadêmico (estagiário) tem a possibilidade do contato com a realidade de sua profissão, por vezes, o primeiro. A prática do estágio supervisionado tem como finalidade proporcionar aos estudantes de graduação, especialmente de licenciatura, a compreensão dos conteúdos estudados, sua aplicabilidade, bem como, a reflexão sobre a função social destes, que busca contribuir na construção da cidadania dos indivíduos. O estagiário deve promover não só a aprendizagem de conceitos basilares das ciências por parte dos alunos em sala de aula, mas também fazer com que relacionem os conteúdos com seus espaços de vivência, formando sujeitos críticos que possam atuar na transformação de sua realidade. Assim, nos dias atuais, tanto os estagiários, quanto os professores, devem estar atentos às transformações do/no espaço e junto delas irem (re)pensando sua prática, isto é, pensar em metodologias que contemplem o público que está sendo atendido e promover meios que o aproxime de seus alunos. Trata-se de compor sua identidade profissional docente, a qual se (re)constrói cotidianamente em um processo contínuo de vivências e mutualidades.

Published: September 2020

Geografia e Fotografia têm uma longa história conjunta, e ambas compartilham do interesse pela paisagem. A grande variedade de recursos atualmente disponível fez da Fotografia uma excelente ferramenta de trabalho para Geógrafos e Professores de Geografia. Apesar disso, nem sempre estes profissionais tem utilizado a Fotografia para além dos aspectos estéticos, explorando questões temáticas e conceituais. Este artigo busca apresentar o relato de algumas experiências desenvolvidas na disciplina de Fotogeografia dos cursos de Geografia da UFPel, demonstrando como a Fotografia vem sendo utilizada para o ensino de alguns temas e conceitos geográficos relevantes. Para tanto, foram realizadas diferentes propostas que incentivaram os alunos a materializar nas fotos alguns conceitos e temas abordados pela Geografia, especialmente a Geografia Urbana. Com a realização destas propostas, observou-se que o entendimento da complexidade técnica de certos procedimentos empregados na realização de algumas fotos leva a uma valorização da Fotografia como meio artístico e de comunicação, e que muitos alunos acabam por descobrir também o potencial da Fotografia como instrumento científico, enxergando no espaço cotidiano conceitos por muitas vezes abstratos.

Numerical simulation and influence factors analysis for dynamic characteristics of squeeze film damper
Authors: Zhou Hai-Lun , Chen Xi , Zhang Chen-Shuai
Published: September 2020

To accurately and efficiently calculate the dynamic characteristics of squeeze film damper (SFD), the influences of different parameters on computational fluid dynamics simulation were analyzed. The simulation was verified by theoretical formula of SFD based on the short bearing and semi-oil film hypothesis considering the oil film inertia force. Numerical simulation results have shown that mesh stiffness value can guarantee the convergence without influence on results. The mesh sizes have obvious influence on simulation results, while the influence of circumferential mesh size is comparatively weak. When there are more than 200-time steps in a cycle or more than 2 cycles are selected, it will take more computation time but with less influence on results. When the length-diameter ratio of SFD is smaller, the numerical calculation results have a better agreement with the theoretical results. The research will provide a reference for the options of simulation parameters of SFD while taking into account both analysis precision and computer time.

Authors: Purohit Deepika , Manchanda Deeksha , Makhija Manish , Rathi Jyoti , Verma Ravinder , Kaushik Deepak , Pandey Parijat
Published: September 2020

Background:

Compared to traditional dosage methods, the Novel Drug Delivery Systems
(NDDS) provide various advantages. In the last few years, the interest shifted to works focused on the
novel drug delivery methods for small and large molecular drug carriers utilizing particulate drug delivery
systems as well. It is evident from the last decade as observed in increased number of patents in
this field that the technology has evolved tremendously.

Objective:

Drug carriers utilized by this novel technology include liposomes, dendrimers, polymeric
nanoparticles, magnetic nanoparticles, solid lipid nanoparticles, and carbon nanomaterials. Various
forms of polymers have been used in the production of nanocarriers.

Methods:

Nanocarriers are colloidal systems varying in size from 10 to 1000 nm. This technology is
now used to identify, manage and monitor numerous diseases and physical methods to alter and enhance
the pharmacokinetic and pharmacodynamic properties of specific types of drug molecules.

Results:

Nanoparticles can be formulated by a number of techniques including ionic gelation, crosslinking,
coacervation/precipitation, nanoprecipitation, spray drying, emulsion- droplet coalescence,
nano sonication techniques, etc. Several methods are used with which these nanoparticles can be characterized.
These methods include nuclear magnetic resonance, optical microscopy, atomic force microscopy,
photon correlation spectroscopy and electron microscopy, surface charge, in-vitro drug release,
etc.

Conclusion:

In the present review, the authors have tried to summarize recent advances in the field of
pharmaceutical nanotechnology and also focused on the application and new patents in the area related
to NDDS.
Nanostructured Lipid Carriers- A Versatile Carrier for Oral Delivery of Lipophilic Drugs
Authors: Patel Priyanshi , Patel Mitali
Published: September 2020

Background:

Around 40% of newly discovered chemical entities in pharmaceutical
industries have poor water solubility and hence they suffer from low oral bioavailability owing to undesirable
physicochemical and pharmacokinetic properties. So, it is the challenge for the formulation
scientists to develop the oral formulation that can mitigate the pitfalls associated with such lipophilic
drugs.

Methods:

Lipid nanoparticles hold a promising tool to decrease the pitfalls of lipophilic drugs as lipid
components can effectively increase the absorption of drugs, which leads to improvement in oral
bioavailability. They are also considered as safe because they are made up of physiological lipids,
which are biocompatible and biodegradable in nature. Amongst the lipid nanoparticles, Nanostructured
Lipid Carriers (NLCs) are the second-generation lipid nanoparticles and were developed to conquer the
limitations of solid lipid nanoparticles. They increase the solubility, permeability, reduce metabolism,
P-glycoprotein efflux, and thereby increase the bioavailability of poorly soluble drugs.

Conclusion:

This review highlights the various aspects of NLCs, such as structural components, types,
in vivo fate, pharmacokinetic, toxicity, recent applications, and patent reviews of NLCs in drug delivery.
PHYSICO-MECHANICAL, THERMAL AND ELECTRICAL CHARACTERISTICS COMPOSITE MATERIALS BASED ON POLYURETHANE BINDER AND MINERAL FILLERS
Authors: Sulaberidze V. Sh. , Skorniakova E. A.
Published: September 2020

The article presents the results of studies of the physical, mechanical, thermal and electrical characteristics of composite materials based on polyurethane as a binder and mineral fillers from fine powders AlN, Al(OH)3, SiO2, CaSiO3 with a content of up to 70 wt.%. These composite materials are used to create modern sealants and dielectric coatings that meet special requirements for strength, elasticity, heat resistance, including those that do not support combustion (by using flame retardants). Dependences of tensile strength, coefficient of elasticity, modulus of elasticity under compression and hardness of samples, electrical resistivity and thermal conductivity on the mass content of the filler were determined. It was found that in terms of the combination of physical and mechanical characteristics, the compositions based on the applied polyurethane are more durable, elastic and resilient than compositions based on a silicone binder with the same fillers previously studied by the authors.

Student Performance in Online and Traditional Sections of an Undergraduate Management Course
Authors: Daymont Thomas , Blau Gary
Published: September 2020

Few previous studies comparing online and traditional courses have focused on undergraduate management courses. Our results complement previous analyses finding that, when we control for factors such as class, major, and GPA, students in online courses do as well in objective measures of performance, but not better than students in traditional courses. We also found that in the online sections, females performed at least as well as males. We discuss these results in relation to some changes in online education and the persistent perception by some that online education is somewhat problematic because students need more discipline in online courses.
Diagnose van zenuwstelsellymfoom met aantasting van de nervus ischiadicus met behulp van computertomografie en echogeleide dunnenaaldaspiratie bij twee katten
Authors: Gory G. , Couturier J. , Cauvin E. , Fournel-Fleury C. , Couturier L. , Rault D. N.
Published: September 2020

Twee katten werden aangeboden met een recente voorgeschiedenis van problemen met stappen en springen. Neurologisch onderzoek toonde in beide gevallen een lumbosacraal ruggenmergletsel of nervus ischiadicusletsel aan, met een bijkomend cervicothoracaal-spinaal letsel in het tweede geval. De differentiaaldiagnose bestond uit neoplasie, ontsteking/infectie (neuritis, meningomyelitis, discospondylitis) en compressieve aandoeningen, zoals discus hernia. In het eerste geval werd met behulp van computertomografie (CT) een verdikte nervus ischiadicus aangetoond vanaf het foramen intervertebrale L7-S1 tot aan het distale derde deel van de femur door verhoogde contrastopname. In het tweede geval toonde CT ook een verdikte nervus femoralis en een extradurale massa aan die een milde compressie veroorzaakte van het ruggenmerg ter hoogte van T1-2 en T3-4. Met behulp van echografie kon een fijnenaaldaspiraat genomen worden van de aangetaste nervus ischiadicus. Cytologisch onderzoek suggereerde een traag evoluerend en kleincellig lymfoom in het eerste geval en bevestigde in het tweede geval de diagnose van een hooggradig lymfoom. Beide lymfomen behoren tot het subtype van het grootcellige granulaire lymfoom.

Published: September 2020

In deze studie werd het voorkomen van oorhematomen bij gespeende biggen onderzocht en werd nagegaan of het voorkomen gerelateerd was aan bepaalde risicofactoren. In totaal werden vijf opeenvolgende groepen biggen (n=10.657) binnen een bedrijf onderzocht vanaf het spenen (drie weken) tot het einde van de biggenbatterij (tien weken). De gemiddelde incidentie per groep bedroeg 2,3%, variërend van 1,3% tot 2,9%. Bij bargen was de incidentie 2,1%, bij zeugen 2,5% (P > 0,05). De incidentie bij biggen van eersteworpszeugen bedroeg 0,92%, bij biggen van meerdereworpszeugen was dit 2,45% (P < 0,001). De meeste nieuwe gevallen traden vier à vijf weken na het spenen op. Het risico op het ontstaan van een oorhematoom was ruim tweemaal groter langs de zijde waar een oormerk aanwezig was (RR = 2,28 [1,74 – 2,98]). Verder onderzoek, bij voorkeur op meerdere bedrijven, is wenselijk om de resultaten te bevestigen en/of te verklaren en om de controlemaatregelen te optimaliseren.

Enzoötische abortus veroorzaakt door Chlamydia (C.) abortus is nog steeds de meest voorkomende oorzaak van reproductiestoornissen bij schapen. Bij runderen wordt C. abortus geassocieerd met infecties van het geslachtsstelsel en mastitis. In de voorliggende studie werden Belgische schapen (n=958), geiten (n=48) en runderen (n=1849) onderzocht aan de hand van de ID ScreenTM Chlamydia abortus indirecte multispecies antistof ELISA. Bij de schapen werd de hoogste prevalentie gevonden in Limburg (4,05%). De dieren van Antwerpen, Brabant en Luik waren negatief. De prevalentie in de overige vijf regio’s was laag (0,24% tot 2,74%). Van negen geitenboerderijen was slechts één bedrijf uit Luxemburg positief. Bij de runderen werd de hoogste seroprevalentie in Waals-Brabant (4,23%) gevonden. De dieren uit Limburg en Namen waren negatief. De prevalentie in de overige zeven regio’s varieerde van 0,39% tot 4,02%.

Published: September 2020

De extragonadale spermareserves bevinden zich in de epididymis en de vas deferens. Deze spermatozoa zijn fertiel en kunnen gebruikt worden in een laatste poging om fertiele spermatozoa van een terminaal zieke of stervende hengst te bewaren. Epididymides worden verzameld via routinecastratie. Na gekoeld transport van de testikels en de epididymides worden de spermatozoa via retrograde flushing of via de flotatiemethode verzameld. Met een retrograde flushingtechniek wordt er een hogere opbrengst van spermacellen bekomen dan met de flotatiemethode. Epididymale spermatozoa worden ingevroren via standaardprotocollen.

Published: September 2020

In deze casuïstiek worden twee honden beschreven die in België blootgesteld werden aan Anaplasma phagocytophilum. Het eerste geval werd aangeboden omwille van acute zwakte en collaps. Bij deze hond werd immuungemedieerde hemolytische anemie gediagnosticeerd. Een serologiepanel voor vectoroverdraagbare infecties toonde een sterk gestegen antistoftiter voor A. phagocytophilum. De hond herstelde tijdens een therapie met doxycycline. Bij het tweede geval werd immuungemedieerde glomerulopathie gediagnosticeerd. Op hetzelfde moment werd bij de hond een erg uitgesproken stijging van antistoffen voor A. phagocytophilum vastgesteld. De relatie tussen granulocytaire anaplasmose en “protein-losing” nefropathie is onduidelijk bij de hond. Er wordt echter vermoed dat A. phagocytophilum geassocieerd zou zijn met nierschade, zoals beschreven bij het tweede geval.
Geen slachthuizen, wel vleeshuizen in onze oude steden: casus Gent (1251-1857)
Authors: Devriese L.
Published: September 2020

In dit artikel wordt getracht een antwoord te formuleren op de vraag waar volwassen runderen geslacht werden in onze steden voordat de openbare slachthuizen vanaf halverwege de jaren 1800 in gebruik kwamen. Daarover zijn opvallend weinig archiefgegevens voorhanden en in de literatuur wordt in alle talen over dit onderwerp gezwegen. De hypothese wordt naar voor gebracht en verdedigd dat het niet gebeurde op of bij de hier kort beschreven veemarkten of ‘vleeshuizen’ en evenmin op andere daarvoor bestemde slachtplaatsen op openbaar domein, al of niet in open lucht. Alles wijst erop dat de vleeshouwers hun aangekochte runderen slachtten en versneden op privéterrein: op hun eigen erven of in eigen gebouwtjes. Dit onderzoek is beperkt tot Gent, maar kan wellicht geëxtrapoleerd worden naar andere oude steden in Vlaanderen en misschien zelfs daarbuiten.
Christelijk geluk in een seculiere cultuur. Een verantwoording van de belangrijkste theologische keuzes in de Gewone Catechismus
Authors: Huijgen A. , Pleizier T.T.J. , Te Velde R.T.
Published: September 2020

This article presents an account of the theological choices made in the recently published Gewone Catechismus (Ordinary Catechism). Against the background of secular culture, the GC opts for an eschatological approach that defies hedonism, paradoxically by making ‘happiness’ (‘geluk’) the central theme. The architecture of the GC is trinitarian: trusting the Father in prayer, following Christ in obedience to his commandments, and expecting God’s Kingdom through the Spirit. While the GC has no official confessional status, like the Heidelberg Catechism, it still is a confessional text, as all theological discourse has confessional implications.

Published: September 2020

Against a background of students' lack of understanding of monetary and fiscal policy, the research conducted aims to develop learning media that is expected to be able to overcome these problems. Learning media developed using a mind mapping and web-based approach. This type of research used in this study is Research and Development with the 4D development model (Define, Design, Develop, & Disseminate). Product trials conducted limited to 20 students by analyzing the results of the pre-test and post-test, which were calculated using the gain score and t-test. The test results show that web-based mind mapping learning media can improve students' understanding. Because by using this learning media, the active mental processes of each student become aroused, the material provided so that it is easy to remember. However, this web-based mind mapping learning media is still being tested on a limited basis, so it needs to be trialed in the broader audience to get more productive advice.

Published: September 2020

BACKGROUND

Asthma is a major chronic disease affecting 8.6% of children in the United States.

OBJECTIVE

The purpose of this research was to assess the use of clinical simulation scenarios using augmented reality technology to evaluate learning outcomes for nurse practitioner students studying pediatric asthma management.

METHODS

A mixed-methods pilot study was conducted with 2 cohorts of graduate pediatric nurse practitioner students (N=21), with each cohort participating for 2 semesters.

RESULTS

Significant improvements in pediatric asthma test scores (P<.001) of student learning were found in both cohorts at posttest in both semesters. Student satisfaction with the augmented reality technology was found to be high. The focus group discussions revealed that the simulation was realistic and helpful for a flipped classroom approach.

CONCLUSIONS

The study results suggest augmented reality simulation to be valuable in teaching pediatric asthma management content in graduate nursing education.
Counselor Efficiency at Providing Feedback in a Technology-Based Behavioral Weight Loss Intervention: Longitudinal Analysis (Preprint)
Authors: Fahey Margaret C , Klesges Robert C , Kocak Mehmet , Gladney Leslie A , Talcott Gerald W , Krukowski Rebecca A
Published: September 2020

BACKGROUND

Feedback for participants’ self-monitoring is a crucial and costly component of technology-based weight loss interventions. Detailed examination of interventionist time when reviewing and providing feedback for online self-monitoring data is lacking.

OBJECTIVE

The aim of this study was to longitudinally examine the time counselors spent providing feedback on participant self-monitoring data (ie, diet, physical activity, weight) in a 12-month technology-based weight loss intervention. We hypothesized that counselors would compose feedback for participants more quickly over time.

METHODS

The time the lay counselors (N=10) spent reviewing self-monitoring records and providing feedback to participants via email was longitudinally examined for all counselors across the three years of study implementation. Descriptives were observed for counselor feedback duration across counselors by 12 annual quarters (ie, 3-month periods). Differences in overall duration times by each consecutive annual quarter were analyzed using Wilcoxon-Mann-Whitney tests.

RESULTS

There was a decrease in counselor feedback duration from the first to second quarter (mean 53 to 46 minutes; P<.001), and from the second to third (mean 46 to 30 minutes; P<.001). A trend suggested a decrease from the third to fourth quarter (mean 30 to 26 minutes; P=.053), but no changes were found in subsequent quarters. Consistent with the hypothesis, counselors may be increasing their efficiency in providing feedback; across 12 months, counselors spent less time reviewing participant self-monitoring and composing feedback (decreasing from mean 53 to 26 minutes).

CONCLUSIONS

Counselors used increasingly less time to review online self-monitoring data and compose feedback after the initial 9 months of study implementation. Results inform counselor costs for future technology-based behavioral weight loss interventions. For example, regardless of increasing counselor efficiency, 25-30 minutes per feedback message is a high cost for interventions. One possibility for reducing costs would be generating computer-automated feedback.

A Comparative Study of Subjective Well-Being and Psychological Problems Related to Problematic Internet Use among University Students With and Without Disabilities (Preprint)
Authors: Raya Antonio , Herruzo Carlos , Ruiz Rosario , Lucena Valentina , Herruzo Javier , Pino María José
Published: September 2020

BACKGROUND

Problematic internet use (PIU) and the psychological variables related to subjective well-being among people with disabilities has received very little attention in scientific literature.

OBJECTIVE

The objectives of this study were to observe whether people with disabilities experience PIU like that of young people without disabilities; to relate PIU to psychological distress and problems in young disabled people, and to determine whether these problems are similar to or different from those experienced by young people without disabilities.

METHODS

PIU was evaluated using the Internet Addiction Test (IAT) and psychological distress was evaluated using the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM). The sample comprised 1,794 young people (408 university students with disabilities and 1,386 university students without disabilities).

RESULTS

The group of university students with disabilities showed less PIU than the non-disabled students, but the worst scores in variables referencing psychological discomfort were found among those students with disabilities who also had PIU.

CONCLUSIONS

PIU is related to bigger problems in disabled people for whom, with regard to problems in social relationships or the probability of self-harm, it represents a higher risk than for people without disabilities.
Intelligent Isolation medical observation management system based on Internet of things (Preprint)
Authors: Sun Wensheng , Wang Chunmwei , Ling Feng , Miao Ziping , Wu Guangsong
Published: September 2020

BACKGROUND

Since the new coronavirus infection was found in December 2019, it has caused a large-scale spread in the world. By zero o'clock on May 24, 2020, the total number of confirmed cases in the world has exceeded 5.3 million and the number of deaths has exceeded 340000. Considering the characteristics of the new coronavirus, such as strong infectivity and long incubation period, it is very important to isolate and observe the suspicious population all day and find the suspected cases with symptoms as soon as possible.

OBJECTIVE

To use remote monitoring of vital signs such as body temperature and cough, avoid traditional on-site medical observation, and effectively reduce the workload of medical staff and the risk of infection.

METHODS

The Internet of things isolation medical observation system based on wristwatch was established. The system consists of six modules: equipment management, vital signs monitoring, remote control, early warning report, statistical analysis and multi organization user management. Generally speaking, it can collect, transmit, store and analyze the location, temperature, blood oxygen, blood pressure, heart rate, respiratory rate, cough and other vital sign information of the observed population in real time by using the wristwatch with built-in sensors, mobile Internet and cloud based database management, and give early warning for suspicious situations.

RESULTS

This highly customizable report design makes it easy to be embedded into the third-party management system, so that further analysis, early warning and prediction modules can be built in a larger population. Managers can log in to the platform or mobile app to monitor and manage the observed personnel. Their user-friendly interface is intuitive and easy to navigate, which will ultimately help save time and resources, and more importantly, reduce the occupational exposure risk of medical personnel.

CONCLUSIONS

The wristwatch based medical isolation observation system can be used to screen the new coronavirus infection, which is stable and reliable.
Magnetic Reconnection: Phantom Theory
Authors: Akasofu Syun-Ichi
Published: September 2020

In any scientific field, there is always a possibility, in which a particular theory dominates for many years. In this paper, the theory of magnetic reconnection in solar physics and auroral physics is reviewed as an example. It has prevailed for more than a half century in both fields as the “only one” without a concrete progress in understanding the source of energy for solar flares and auroral activities. This unusual situation is analyzed why and how it occurred. Since such a situation could occur in any scientific field, it may be useful to analyze how this situation happened. Actually, it is pointed out that a study of global warming may also be in a similar situation.

Fournier's gangrene is rare necrotizing soft tissue infection affecting the perianal, perineal, and genital areas. The mean age of the reported cases was found to be at 55 y, predominantly in men. It occurs due to insufficient blood supply to the affected areas, along with the presence of an infection. Delay in the treatment is associated with a higher mortality rate, up to 90%, as the condition might progress to septic shock and other complications. Treatment requires urgent surgical debridement of all the necrotic tissue along with high doses of broad-spectrum antibiotics. Empirical broad-spectrum antibiotic therapy is to be initiated as soon as possible until the results of the culture cause modifications in the therapy.
Factors Determining the Characteristics of Cocoa Soil in Sulawesi
Authors: Prastowo Erwin , Baon John Bako
Published: September 2020

Sulawesi exhibits unique land characteristics as a result of complex geological and geomorphological processes. The information related to what extent of theseprocesses affect regional soil characteristics is still limited. An investigation was performed on cocoa farms from three major cocoa producers, i.e. South Sulawesi, Central Sulawesi, and Southeast Sulawesi. A research was done to point out the key variables contributing to cocoa soil characteristics. Soil survey was performed based on available local information to collect top soil composite samples, i.e. 0–30 cm depth, in the circle of cocoa stand within 50–75 cm radius. A routine soil analysis was done to evaluate soil texture, organic carbon (C), total nitrogen, K, Ca, Mg, soil pH (H2O), and some micronutrients, i.e. Fe, Cu, and Zn. To simplify the complexity, the multivariate data was submitted into principal component analysis (PCA). Additional mapping of soil variable gradient through inverse distance weighting (IDW) interpolation was included in the analysis to improve our interpretations. Data show that the variability for almost all investigated variables is high with coefficient of variation (CV) of up to about 118% for Fe. While low variability with CV about 10% was observed for soil pH (H2O). The PCA demonstrates that the first five principal components (PCs) account for 56.89% of variance in the original variables. Two factors to be considered to explain the variation in the PCs was soil texture and parent material. Further analyses exhibit an association of sand, silt, and clay fractions to Southeast, Central, and South Sulawesi. Mineral compositions, such as K, Ca, Mg, Fe, and Zn, exhibit an important contribution to the parent material factor as they define the variability in the PCs. Additionally, the analysis of gradient maps may indicate the two physical environmental conditions, i.e. landform and geological setting, contribute to the specific characteristics of cocoa soil.

Published: September 2020

Cocoa is an important crop to the economies of countries such as Nigeria, Cote D’Ivoire, Ghana and Cameroon in West Africa. This study ascertained the adoption levels of farmers in cocoa rehabilitation programmes in South West, Nigeria. Data for the study were collected from 240 cocoa farmers through the use of interview schedule and focus group discussion. Multistage sampling procedure was used in selecting respondents. Data were analysed using percentage and mean statistics. Results revealed that, adoption index was high in planting young cocoa seedlings under old cocoa trees for the three groups of farmers - farmers that benefitted from government agency cocoa resuscitation programme (98.0%), farmers that benefitted from non-governmental agency cocoa resuscitation programme (94.0%) and farmers that benefitted from both governmental and non-governmental agencies cocoa resuscitation programmes (95.0%). Low adoption index (38.0%, 32.0% and 33.0%) were recorded in coppicing technique for the three groups of farmers, respectively. The most helpful agency in the adoption of cocoa resuscitation programmes was Agricultural Development Programme (M=2.80). To improve the level of adoption of cocoa resuscitation programmes, Federal Government of Nigeria through Ministry of Agriculture should provide more incentives geared towards encouraging increased participation of the organized private sector in cocoa production.
O Conceito de Mediação na Teoria Histórico-Cultural e as Práticas Pedagógicas
Authors: Aparecida Mello Maria
Published: September 2020

Atualmente, a palavra “mediação” tornou-se, de certa forma, comum nas conversas em reuniõespedagógicas e em pesquisas na área da Educação. O termo normalmente é empregado como uma dasatribuições de professoras e professores. A mediação nestes casos é interpretada como se fosse uma “ponte”entre a criança e os conteúdos escolares. Mas, será que realmente esse conceito filosófico tem o significado deelo entre dois extremos que de outra forma seria intransponível? O objetivo deste artigo é discutir esse conceitoa partir da Teoria Histórico-Cultural, bem como relacioná-lo ao desenvolvimento de aprendizagens escolares e,portanto, sua função nas práticas pedagógicas.

Neste artigo, abordamos o processo de produção de álcool antisséptico 70% líquido pela Universidade Estadual do Sudoeste da Bahia (UESB), Campus Itapetinga, como forma de contribuir para o enfrentamento da Covid-19. Trata-se de um relato de experiência quanto à produção e distribuição de sanitizantes. Tais procedimentos seguiram as etapas de estudos dos protocolos da OMS e da ANVISA para produção do álcool 70% em situação de combate à pandemia, e foram adaptados e desenvolvidos pelo Laboratório de Tecnologia de Produtos de Origem Vegetal (LTPOV). A estrutura da UESB e a expertise da equipe para a produção do álcool mostraram a capacidade desse ambiente universitário para se adaptar e cumprir com sua responsabilidade social em torno do enfrentamento de diferentes situações, nesse caso, a pandemia Covid-19.
Crise econômica, pandemia e a política de transferência de renda no Brasil
Authors: Costa Andréa Braz da , Soares Marcos A. Tavares
Published: September 2020

A discussão da renda básica, há muito presente no meio acadêmico, toma forma de um grande debate nacional e encontra espaço na formação da agenda pública como instrumento necessário no combate aos efeitos da Covid-19. O objetivo do artigo é analisar a evolução e importância das políticas de transferência de renda como instrumento de proteção social, destacando o tratamento dado a estas pelo governo brasileiro em momentos de crise, especialmente no contexto da pandemia da Covid-19 e da instituição do Auxílio Emergencial (AE). Para o desenvolvimento do artigo recorreu-se à pesquisa bibliográfica e documental (análise de lei e dados secundários do IBGE, IPEA, MC, CEF etc.) com o propósito de apresentar argumentos que fundamentam o debate acerca das políticas de proteção social. Verificou-se que a pandemia chegou ao Brasil num contexto em que o quadro social se deteriorava em função do aprofundamento da agenda liberal adotada a partir de 2015: o PIB de 2019, em valor real, é menor que o de 2014; a taxa de desemprego até fevereiro de 2020 era quase o dobro da registrada em 2014; e a pobreza se expandiu. Apesar desse quadro, nos primeiros quinze meses do governo Bolsonaro foram excluídas mais de um milhão de famílias do PBF e 25 mil beneficiários do BPC. Diante do agravamento da crise econômica provocado pela Covid-19, o Congresso Nacional aprovou o AE, que alcançou mais de 65 milhões de pessoas. Conclui-se que é necessário manter o AE e incluir boa parte dos 40 milhões de pessoas que não foram atendidas, até que seja aprovado um programa de renda mínima permanente pari passu a reformas estruturais imprescindíveis ao combate à pobreza e às desigualdades.
ESPAÇO E LETRAMENTO NOS TRÊS PRIMEIROS ANOS DO ENSINO FUNDAMENTAL: A REALIDADE OBSERVADA
Authors: Uczak Lucia Hugo , Faller Karine Oliveira
Published: September 2020

Este artigo é parte de uma pesquisa maior, de abordagem qualitativa, que abrange estudos sobre alfabetização e letramento. O objetivo deste texto é apresentar algumas considerações sobre a forma como os professores do bloco pedagógico, que compreende os três primeiros anos do Ensino Fundamental, vem utilizando o espaço de sala de aula como estratégia para o letramento. O campo empírico do estudo é uma escola pública municipal. Buscamos o embasamento legal para a explicar a organização e o objetivo do bloco de alfabetização e abordamos o letramento como processo em constante desenvolvimento na aprendizagem escolar, de modo especial, nas atividades lúdicas.  Ao relacionar as Diretrizes Curriculares Nacionais para o Ensino Fundamental de Nove Anos com as evidências levantadas a partir da coleta de dados, foi possível perceber divergências entre o que a legislação determina para esta etapa e o que está acontecendo na prática, na escola observada. O trabalho com o letramento realizado em um ambiente propício às interações, dando continuidade a Educação Infantil, marcada pelos processos de aprendizagem a partir das vivências, fica registrado apenas no Projeto Político Pedagógico, mas é pouco observado nas práticas pedagógicas. A repetição toma o lugar das brincadeiras, a diversidade de textos perde espaço para fragmentação de palavras e assim, isso acaba refletindo na pouca exploração do espaço de sala de aula, já que as intervenções pouco promovem momentos lúdicos e de interação.
A CONSTRUÇÃO DE SIGNIFICADOS SOBRE A CONDENSAÇÃO DA ÁGUA COM ALUNOS DO 1.º CICLO DO ENSINO BÁSICO
Authors: Varela Paulo , Serra Filipa
Published: September 2020

Este artigo descreve e interpreta o processo de construção de significados científicos sobre a condensação da água, promovido numa turma do 4.º ano de escolaridade, com uma média de idades de 9,4 anos. Ele resulta de uma intervenção pedagógica mais ampla, que incorporou uma abordagem de ensino das ciências baseada na experimentação e investigação. Através da análise do diário de aula, apresenta as conceções iniciais dos alunos sobre o tema em estudo, os processos científicos por eles utilizados nos contextos de condensação criados por um copo de vidro com água e gelo e pelo bafejar para um espelho e identifica momentos de aprendizagem particularmente importantes no desenvolvimento da compreensão da condensação da água, promovidos naqueles contextos. Por fim, apresenta também os resultados da avaliação das aprendizagens dos alunos e tece algumas considerações sobre as implicações para a prática dos professores e para os processos de formação.
UNA VITA PER L’EDUCAZIONE: MEMÓRIAS AUTORREFERENCIAIS DA PROFESSORA MARIA MOCELINI (1878 – 1961)
Authors: Belusso Gisele , Luchese Terciane Ângela
Published: September 2020

O objetivo do presente artigo é narrar, a partir de um caderno de memórias, a história de vida da professora Maria Mocelini, nascida na Itália em 1878, imigrante e que se dedicou à profissão docente no Rio Grande do Sul como servidora pública estadual, de 1907 a 1939. Aposentada, viveu junto à comunidade das Irmãs Scalabrinianas no Colégio Nossa Senhora de Lourdes em Farroupilha/RS, até seu falecimento. O corpus empírico foi constituído pelo caderno de memórias manuscrito produzido pela professora Maria Mocelini e por outros documentos como narrativa de história oral, jornais, relatórios e fotografias. A metodologia foi a análise documental histórica e a história oral. O aporte teórico foi auferido pela História Cultural e História da Educação.  Como resultado, é possível afirmar que a professora “inventou seu cotidiano” na escrita de seu caderno, tematizando a família, a profissão docente e as vivências junto à comunidade das Irmãs Scalabrinianas, deixando assim escritas de si que conformam uma identidade – a de docente pública, dedicada à educação e católica

Published: September 2020

Resumo: A presente pesquisa, de caráter descritivo e documental, teve como objetivo analisar a estrutura organizacional da educação física na Base Nacional Comum Curricular (BNCC) por meio de documentos e pareceres oficiais. Para tanto, foi necessário o estudo das quatro primeiras versões da BNCC–Ensino Fundamental e as considerações dos pareceristas. Os seguintes indicadores foram adotados: a) Texto de apresentação da educação física; b) Estruturação do conhecimento por meio das práticas corporais; c) Objetivos gerais/Competências específicas; d) Objetivos de Aprendizagem e/ou desenvolvimento/Habilidades por Prática Corporal; e) Dimensões do Conhecimento; e f) Progressão do Conhecimento. As análises possibilitaram identificar acolhida de algumas sugestões dos pareceristas na Base, assim como oscilações na estrutura organizacional e nas informações quanto à perspectiva da cultura corporal de movimento. Apesar das oscilações e controvérsias, as contribuições dos pareceristas e o documento como um todo são marcados pela preocupação com uma formação educacional democrática e humana.
