Published: September 2020

Background:Anaplasma phagocytophilum,a tick-borne bacterium that causes granulocytic anaplasmosis, is a neglected pathogen in Brazil, and is diagnosed in several species of domestic and wild animals as well as in humans.Objective:This study aimed to investigate the prevalence of anti-A. phagocytophilumantibodies in Equidae from the state of Rio de Janeiro and to identify possible risk factors for infection.Materials and Methods:A total of 612 blood samples were collected from horses from 15 municipalities within the state. Moreover, an epidemiological questionnaire was administered to evaluate aspects related to seroreaction, taking into account the spatial distribution (properties, municipalities, and mesoregions), management practices, signs of disease, and the individual state of the animals. For the diagnosis, indirect immunofluorescence was performed.Results:In the present study, 124 (20.26%), out of a total of 612, animals with anti-A. phagocytophilumIgG antibodies at titers of 1:80 were detected. Multivariate logistic regression analysis showed that the presence of the infection at the property (P <0.0001) and the origin (P = 0.0095) of the horse were the true risk factors for infection in the state of Rio de Janeiro.Conclusion:This allows to infer that the bacterium is distributed in all mesoregions of the state of Rio de Janeiro and that animals from other states can introduce the infection and make a property a focus of disease; it can also be inferred that these properties are important in the maintenance of the disease and the permanence of bacteria circulating in horses. It is also noteworthy that this was the first identification of mules as hosts ofA. phagocytophiluminfection.
Investigation of the Structural Behaviors of One-way HVFA-SCC Slabs Reinforced by GFRP Bars
Authors: Zhou Lingzhu , Dong Pengcheng , Zheng Yu , Song Gangbing , Wang Xiaolu 
Published: September 2020

Background:
The corrosion of steel bar leads to the deterioration of structural behaviors,
high cost maintenance, shortened service life. The bridge deck structures constructed by Fiber Reinforced
Polymer (FRP) bars and High-Volume Fly Ash-Self-Compacting Concrete (HVFA-SCC) can
achieve low energy consumption, sustainable construction and high durability. However, the structural
behaviors of this bridge deck are still unclear.

Objective:
The aim of this paper is to study the structural behaviors, including ultimate loads, failure
mode, cracking behavior, deflection and strain of one-way HVFA-SCC slabs reinforced with Glass-
FRP (GFRP).

Experimental:
Eleven full-scale HVFA-SCC slabs, varying in reinforcement diameter, reinforcement
ratio, shear-span ratio, the type of reinforcing materials and concrete matrix materials, were
tested by using a four-point bending load.

Methods:
The test results of tested specimens were compared with existing theoretical models, such
as crack load, ultimate bearing capacity, maximum crack width, maximum crack space and deflection
predicted model.

Results:
The GFRP reinforced HVFA-SCC slab exhibits similar structural behaviors to the GFRP
reinforced NC slab. The maximum crack width of HVFA-SCC slab is significantly increased by
using GFRP bars with a diameter of 19 mm.

Conclusion:
It is concluded that it is feasible to use HVFA-SCC instead of NC combined with
GFRP bars in bridge deck structures. The stress limit of concrete materials (0.45fc) is the main governing
factor for the service limit state (SLS) of GFRP reinforced HVFA-SCC slabs. The maximum
crack width of GFRP reinforced HVFA-SCC slabs can be predicted by using EHE-08 and GB
50608-2010 models.

Authors: Ahdiati Triana 
Published: September 2020

The development of local identity reflecting the local wisdom in the tourism development aims at maximizing the local values in developing the area. This research-based paper describes the local wisdom and the development of local identity to promote cultural tourisme in Banyumas. By using a qualitative method and a case study as its approach, the research reveals that the tourism development in the Banyumas regency has not focused on the development of its local identity yet. Cablaka as the local identity of the Banyumas society has not become the way of life. In this case, it has not absorbed into every sector of the Banyumas people’ lives, including the tourism sector. The local wisdom in the tourism development is important for a society–including the Banyumas society–to get a better regional income. It means the tourism develoment through implementating the local wisdom is able to improve the life condition of a society better than before. So, the tourism development–especially promoting the cultural tourism–in the Banyumas regency does need to develop the local identity through its local values.
HEPATOPROTECTIVE ACTIVITY OF ETHANOLIC STEM BARK EXTRACT OF KNEMA ATTENUATA (HOO K. F. AND THOMSON) WARB
Authors: H. SUPRIYA RAJA 
Published: September 2020

Objective: To investigate the hepatoprotective activity of ethanolic stem bark extract (ESBE) of Knema attenuata against carbon tetrachloride (CCl4) induced hepatotoxicity in Wistar rats using both in vivo and in vitro models.
Methods: Animals were treated orally with ESBE (250 mg kg-1 and 500 mg kg-1) once daily for 6 d and CCl4 on the 4th d. On the 7th d, animals were sacrificed and the blood samples were collected to measure the serum levels of biochemical parameters, whereas the liver homogenates were utilized for estimating the antioxidant defense. The hepatoprotective efficacy of the extract was further ensured in vitro using human liver hepatocellular carcinoma (HepG2) cell line against CCl4 induced toxicity. The cell line viability was determined using 3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay.
Results: ESBE effectively reduced (p<0.001) the elevated serum levels of Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), and Alkaline phosphatase (ALP) when compared to the toxicant control group. ESBE 500 mg kg-1significantly raised the antioxidant defense (p<0.0001) by reducing the malondialdehyde (MDA) level and enhancing hepatic reduced glutathione (GSH) level in comparison to the CCl4 control group. The in vitro effect was investigated using CCl4 exposed HepG2 cells. Pretreatment with ESBE showed a dose-dependent increase in percentage cell viability ranged between 44 to 57% at 12.5-100 μg ml-1concentrations (p<0.001, when compared to the control cells).
Conclusion: Present study confirms the hepatoprotective activity of the stem bark extract of K. attenuata against CCl4‑induced liver damage.

Authors: DARMADA PUTU DEWINTA , SURYANA KETUT 
Published: September 2020

Objective: Anemia is responsible for poor outcomes in HIV/AIDS patients. It’s related to disease progression, morbidity, and mortality. Antiretroviral therapy (ART) agent, zidovudine (ZDV) is also known to trigger anemia in the early initiation. However, studies found improved hemoglobin (Hb) levels of HIV/AIDS patients several months after ART routinely taken. This study aims to find the impact and correlation of ART on the hemoglobin level of HIV/AIDS patients.
Methods: A retrospective cohort study was done at Merpati Clinic, Wangaya Hospital, Denpasar-Bali, Indonesia. Data were collected from medical records and laboratory results. A total sample of 64 HIV/AIDS patients with at least 6 mo on ART was included in this study.
Results: Anemia was found in 34 (53.1%) of patients before ART initiation. After taking ART for 6 mo, we observed a significant improvement in patients’ hemoglobin levels, 48 (75%) shows increased hemoglobin levels. The paired t-test revealed a correlation between ART and Hb level (p<0.001). Fourteen (43.8%) patient taking ZDV shows no improvement, even declining of Hb level. Chi-square analysis performed with p = 0.001 to ZDV and lower or no improvement of hemoglobin level. Both results considered statistically significant (p-value less than 0.05) with a confidence interval (CI) of 95%. Relative risk (RR) of no improvement or decline in Hb level is 7 folds higher in the ZDV group than the non-ZDV group.
Conclusion: This study concludes that ART affects hemoglobin levels in HIV/AIDS patients. Zidovudine regimen is more prone to lower or no increase of Hb.

The income of smallholder coffee farmers can be increased by optimizing the added value of the product through increased entrepreneurial capacity. Coffee farmers need to adopt innovations and new approaches that are more sustainable with organic farming systems. The purposes of this study are; (1) identifying differences in characteristics, support of government extension services, private extension agents, and environmental support for smallholder coffee farmers and (2) analyzing the effect of characteristics, government extension services, private extension agents, and environmental support on the entrepreneurial capacity of smallholder coffee farmers. This study was carried out at Arabica Coffee Center in Bondowoso Regency and Robusta Coffee Center in Malang Regency, East Java from August to October 2019. Data were collected through interviews with questionnaires in a total of 376 smallholder coffee farmers. Data were analyzed using descriptive (SPSS) and inferential statistics (structural equation model/SEM analysis using Smart PLS). The results of research showed that non formal education and roles of private extension agents were found to be low. Moreover, motivation, government extension support, environmental support, and entrepreneurial capacity of smallholder coffee farmers were categorized as moderate. Factors significantly influenced entrepreneurial capacity of coffee farmers included: characteristics of farmers, government extension support, roles of private extension agents, and environmental support. The role of government to strengthen private extension agents is possible through partnership between coffee farmers, government and exporter or private sectors.

Published: September 2020

Resumo: A escola da contemporaneidade provocou transformações na atuação docente. A década de 80, marcada pelos movimentos sociais, e pela luta a favor da democratização do ensino, traz para o interior da escola a população que sempre esteve à margem das políticas educacionais. Torna-se imperativo uma reorganização da escola e também, dos novos docentes, ainda mais comprometidos com a transformação social, e com uma educação inclusiva. A formação inicial dos novos professores perpassa pela participação nos estágios supervisionados, entendido aqui como um momento fundamental no processo formativo. Quais são as contribuições dos trabalhos acadêmicos (2008-2018), para a produção de conhecimento na inter-relação entre estágio supervisionado e educação inclusiva? Este estudo tem como objetivo mapear e discutir as contribuições dos trabalhos acadêmico-científicos que abordem a inter-relação entre o estágio supervisionado e educação inclusiva. O método utilizado foi a pesquisa bibliográfica buscando artigos, teses e dissertações em dois repositórios acadêmicos, a saber: Associação Nacional de Pós-Graduação e Pesquisa em Educação (ANPED), e Biblioteca Digital Brasileira de Teses e Dissertações (BDTD). Mostra a sua relevância ao abordar que a formação inicial precisa contemplar no designer pedagógico das instituições superiores a partir das demandas pedagógicas, reflexão e ressignificação das práticas dos estagiários por meio de uma estrutura formativa, tendo como princípio a práxis dialógica e transformadora. Além de recomendar a realização de outras pesquisas que mostrem essa inter-relação tão necessária e urgente.

Methodological basis for designing a digital simulator of pedagogical activities
Authors: Galiakberova A. A. , Galyamova E. Kh. , Matveev S. N. 
Published: September 2020

Introduction. The article presents the foundations of the concept of a digital simulator of pedagogical activity. Its characteristics allow us to see the possibilities of modeling pedagogical activity from the point of view of implementing the principles of the activity approach. The purpose of this research is to create a concept and methodological toolkit as a plot composition for programming a simulator of pedagogical activities for teaching to solve geometric problems. The content of one of the storylines on the topic “Orthocenter of a triangle” is shownMaterials and Methods. The modern system of higher education trains teachers for professional activities in the global information society. The development of information and digital technologies involves active use of distant education tools, which means educational technologies implemented using information and telecommunication networks with the indirect interaction of students and teachers. Due to these requirements, the paper considers the possibilities of simulation in the process of professional training of future school teachers. The following research methods were used: pedagogical experiment, observation and modeling, as well as analysis of existing simulators in the higher education system of the Russian Federation [9, 10, 11, 14] and foreign educational systems as well [20].Results. There has been developed a concept and adaptation of the mathematical content of the simulator [16] to the level of specialized secondary education. To create such a simulator, a bank of pedagogical situations and options for their solution was created, the source of replenishment of which is the pedagogical practice of students at school. We see the prospect that the interaction of the simulator should be built in such a way as to meet the potential user needs and the requirements of the professional standard [19]. The concept of a simulator for teaching to solve geometric problems is based on the theoretical foundations of elementary geometry and methods (techniques) for solving problems of increased complexity in geometry (profile level, Unified State Exam, Olympiad problems), teaching methods for geometric problems, cognitive psychology.Discussion and Conclusions. The article presents a model for simulating the actions of a future mathematics teacher in the process of organizing the solution of a geometric problem from the point of view of didactics, psychology, methods and axioms of geometry. An experimental base has been prepared for a future pedagogical experiment on the introduction of a simulator into the educational process of training mathematics teachers.

Published: September 2020

Europe-wide activities to improve biosafety and biosecurity performed within the frameworks of the European Union (EU)-funded Joint Actions EMERGE and QUANDHIP led to the development of an Integrated European Checklist for Laboratory Biorisk Management (ECL).
To better understand different approaches shaping biorisk management (BRM) systems on an operational level in high containment laboratories, the ECL was used to map the implementation of BRM in 32 high containment laboratories in 18 countries in Europe. The results suggest that the BRM elements referring to standard microbiological working practices and the handling of infectious material were fulfilled particularly well. The elements safety exercises involving internal and external emergency responders, and appropriate decommissioning plans were not fulfilled particularly well. BRM in Biosafety Level (BSL) 4 laboratories handling Risk Group (RG) 4 viruses appear to vary among each other less than BSL3 laboratories handling RG 3 bacteria. It is important to agree on comparable regulations in Europe as high containment laboratories are indispensable for a safe, quick and effective response to public health threats. As high containment laboratories may also present a public health risk it is crucial to have robust BRM on organisational and operational levels.
