Compreender para retextualizar: investigando a retextualização em um resumo escrito conjuntamente
Authors: De Melo Pereira Márcia Helena , Martins Pinchemel Amorim Marina
Published: June 2020

A retextualização é tida como uma grande ferramenta para o trabalho com os gêneros do discurso, visto que se trata da produção de um novo texto a partir de um ou mais texto(s)-base. No intuito de ampliar as discussões a respeito dessa temática, este artigo busca investigar como se apresenta o fator compreensão no processo de produção textual de um resumo escrito por uma dupla de estudantes universitários, a partir do ensaio de Toledo (1994). Para tanto, analisamos o texto a partir de um olhar processual, ou seja, de sua gênese. Fundamentamo-nos teoricamente em Flower e Hayes (1981), Prado (2019), Bakhtin (1997), Marcuschi (2010), Matencio (2002), Dell’Isola (2007), Machado (2010), Paviani (2010) e Koch e Travaglia (2015). A análise dos dados evidenciou que a compreensão é um fator fundamental no processo de retextualização, sendo uma de suas características basilares para que o processo não seja considerado mecânico.
A argumentação no gênero discursivo contrato: uma análise dos modalizadores deônticos
Authors: Gonçalves de Deu Katia Regina , Pereira do Nascimento Erivaldo
Published: June 2020

A presente pesquisa tem como objetivo analisar e descrever o funcionamento semântico-argumentativo dos modalizadores deônticos no gênero discursivo Contrato, cuja finalidade é estabelecer um acordo entre pessoas que transferem, uma para a outra, determinados direitos ou se sujeitam a obrigações. A fundamentação teórica adotada neste trabalho tem base nos estudos sobre a Modalização Discursiva, apresentada por Lyons (1977), Cervoni (1989), Koch (2009), Castilho e Castilho (1993), Neves (2010), Nascimento e Silva (2012), entre outros, bem como na Teoria dos Gêneros Discursivos proposta por Bakhtin (2000 [1979]). Além desse aporte, também se fundamenta na Teoria da Argumentação na Língua, proposta por Ducrot e colaboradores (1988). O corpus é composto por 10 (dez) contratos que foram coletados em instituições públicas e privadas, além da rede mundial de computadores. Essa investigação é de natureza quali-quantitativa, de cunho descritivo e interpretativista, visto que foi descrito o funcionamento semântico-argumentativo dos modalizadores deônticos e os efeitos de sentido provocados por sua utilização nos textos objetos de investigação. O referencial adotado permitiu compreender como esses modalizadores funcionam estrategicamente nesse gênero. Observou-se, ao longo das análises, que, especificamente, os modalizadores deônticos de obrigatoriedade e os deônticos volitivos, não apenas em função da quantidade de ocorrências, mas, sobretudo, em função do papel que eles exercem no próprio texto, constituem-se parte integrante do funcionamento semântico-argumentativo dos contratos e, por esse motivo, são característicos do estilo linguístico desse gênero.
Gênero textual na interface variação-gramaticalização: o caso da perífrase V (E) V2
Authors: Tavares Maria Alice
Published: June 2020

Com base em uma perspectiva de interface variação-gramaticalização, trato do uso variável dos verbos IR e PEGAR na perífrase V1 (E) V2. Faço uso de dados de fala extraídos dos corpora Discurso & Gramática referentes a Natal e ao Rio de Janeiro, e ao corpus VARSUL referente a Florianópolis. Tenho por objetivo analisar o gênero textual como fator condicionador da escolha entre IR e PEGAR para desempenhar o papel de V1 na perífrase V1 (E) V2. Os resultados mostram que IR é favorecido em relatos de procedimentos e relatos de opinião e PEGAR em narrativas de experiência pessoal e narrativas vicárias. É provável que IR e PEGAR tenham iniciado seu processo de mudança em gêneros narrativos, em que a perífrase V1 (E) V2 é mais frequente em várias línguas. Sendo assim, o fato de IR ser favorecido em gêneros textuais diferentes dos narrativos pode ser interpretado como um indício de que está mais avançando no processo de gramaticalização do que PEGAR.
Ensinando a ser mulher um estudo do discurso pedagógico do Almanaque da Família (1947)
Authors: Pereira da Silva Ariana , Pimentel Silva Aguimario
Published: June 2020

O trabalho é um estudo sobre o discurso pedagógico do Almanaque da Família de 1947, que se configurava como um produto da imprensa feminina e orientava as leitoras a assumir o modelo do que seria, à época, uma “mulher moderna”. A partir do aporte teórico da Análise do Discurso, o objetivo é investigar como o conteúdo da publicação produziu determinados sentidos em relação à mulher da década de 1940. Destacam-se os modos de funcionamento desse discurso, observando-se a ênfase dada ao lugar central da mulher no âmbito doméstico, visto como uma espécie de missão essencialmente feminina. Utiliza-se a discussão proposta por Orlandi (1994, 2006) em relação ao discurso pedagógico, tomado como um discurso de tipo autoritário. Além disso, a análise centra-se na noção de memória discursiva, buscando compreender como a ideologia patriarcal construiu, por meio de efeitos de evidência, um modelo feminino socialmente legitimado. A partir das análises, é possível perceber que, de acordo com as condições de produção que o determinavam, o Almanaque da Família ajudou a (re)produzir uma representação feminina conservadora, ancorada no discurso religioso que sustentava o imaginário social da época.
A ARQUITETURA DA SALA DE AULA SOB A ÓTICA DOS USUÁRIOS
Authors: Bernardes Marina , Garcia Lupi Vergara Lizandra , Salles Martins Marcele
Published: June 2020

As salas de aula têm papel importante não apenas no bem-estar dos usuários, mas também, ao facilitar ou dificultar suas atividades, influenciando no aprendizado.  Diante disso, a pesquisa investigou a percepção de professores e estudantes sobre suas salas de aula, a fim de aprimorar o espaço educacional e contribuir com agentes do setor da educação e com projetistas na tomada de decisões sobre o espaço físico da escola. Os dados foram coletados por meio de questionário e poema dos desejos. A amostra foi composta por 57 participantes: 33 estudantes do ensino fundamental (4º ao 7º ano) e 24 professores vinculados às suas turmas. Os resultados apontam que com os elementos inerentes à arquitetura - como janelas (acesso visual e físico a áreas externas), amplitude da sala, revestimentos, conforto térmico, acústico e lumínico - é possível tornar a sala de aula um ambiente adequado ao bem-estar dos usuários. As percepções de estudantes e professores entrevistados são convergentes no tocante à valorização do contato com vegetação e do conforto ambiental: o contato físico com a vegetação foi o único fator com avaliação inferior ao ponto médio da escala, na percepção dos docentes; para os alunos, o anseio pelo “contato com a natureza” foi um dos aspectos mais mencionados; quanto ao conforto ambiental, os professores destacaram a necessidade de melhorar a acústica, e os alunos solicitaram melhoria na iluminação.

AS REGRAS DO JOGO
Authors: Sobreira Fabiano José Arcadio
Published: June 2020

Os concursos de arquitetura e suas regras. Esse é o tema central deste artigo, que procura sintetizar a dinâmica desses eventos, ao mesmo tempo competitivos e colaborativos, a partir da analogia entre as dinâmicas de um concurso e as dinâmicas de um jogo, definido por regras em múltiplas escalas, que resultam da confrontação entre diversos campos. Após breve contextualização sobre o tema, as “regras do jogo” são abordadas em suas três “escalas”: (1) leis; (2) regulamentos e (3) editais (bases). No que se refere às leis, é apresentado breve panorama sobre a legislação nacional relacionada aos concursos de Arquitetura a partir dos anos 1930 até os dias atuais. Quanto aos regulamentos, são apresentadas referências de eventos e textos críticos, em especial a partir dos anos 1950 (quando surgiram os primeiros instrumentos normativos), sob a ótica da recepção editorial de revistas de arquitetura editadas pelo campo profissional. Em relação aos editais (bases dos concursos), são apresentadas reflexões sobre o impacto das regras na dinâmica de alguns concursos e sua recepção no meio profissional, editorial e político. Alguns eventos são citados, com atenção especial para o concurso para o Plano Piloto de Brasília (1957), em que as “regras do jogo” foram determinantes para o processo e seus desdobramentos. O artigo se encerra com reflexões sobre o impacto das regras e sua interpretação no projeto contemporâneo resultante de concursos.

Authors: Farghaly Thoraya A. , Al-Hussain Sami A. , Muhammad Zeinab A. , Abdallah Magda A. , Zaki Magdi E. A.
Published: June 2020

Perimidines are peri-naphtho-fused derivatives of pyrimidine. They are of particular
interest as they are a rare example of an azine in which the lone pair of electrons of
pyrrole-like nitrogen participates in the π-system of the molecule. Perimidine is an interesting
class of heterocyclic compounds. Various synthetic analogs of perimidines have been
prepared and evaluated for many pharmacological activities in different models with desired
findings. They exhibit biological activities as antitumor, antiulcer, antimicrobial, and antifungal
agents. This review is an attempt to organize the synthesis and chemical reactions of
perimidine analogs reported to date systematically since 1955. It should be noted that this
review is the first one that includes the preparation and reactions of the perimidine ring.
Neoadjuvant Strategies Before Radical Prostatectomy for High Risk Prostate Cancer in the Era of New Hormonal Agents
Authors: Tafuri Alessandro , Cerruto Maria Angela , Antonelli Alessandro
Published: June 2020

Prostate cancer (PCa) is a hormone dependent disease including several different patterns from indolent and clinically meaningless to aggressive and lethal disease. Among non-metastatic PCa, high-risk disease represents a therapeutically challenge, given the unfavorable oncological outcomes after exclusive local therapy. Deprivation therapy in the neoadjuvant setting is not recommended prior to radical prostatectomy since it did not provide any survival advantage, although reducing tumor volume, surgical margins rate, local and nodal stage. However, in the few recent years, new hormonal treatments for metastatic PCa emerged, and showed a relevant increase of overall survival with respect to classical androgen
deprivation therapy (ADT). Thus, neo-adjuvant regimens of ADT based on these novel molecules are now under investigation and the results of ongoing clinical trials are expected in order to provide a definitive answer on the real role of neoadjuvant hormonal therapy in the treatment of high-risk localized prostate cancer.
In this narrative review, we underline the role of neoadjuvant therapy before radical prostatectomy in high-risk PCa patients
considering the impact of the new available hormonal agents.

Authors: Yazit Noor Anisah Abu , Juliana Norsham , Das Srijit , Teng Nur Islami Mohd Fahmi , Fahmy Nadia Mohd , Azmani Sahar , Kadiman Suhaini
Published: June 2020

Postoperative Cognitive Dysfunction (POCD) refers to the condition of neurocognitive decline
following surgery in a cognitive and sensory manner. There are several risk factors, which may
be life-threatening for this condition. Neuropsychological assessment of this condition is very important.
In the present review, we discuss the association of apolipoprotein epsilon 4 (APOE ε4) and
few miRNAs with POCD, and highlight the clinical importance for prognosis, diagnosis and treatment
of POCD. Microarray is a genome analysis that can be used to determine DNA abnormalities. This
current technique is rapid, efficient and high-throughout. Microarray techniques are widely used to diagnose
diseases, particularly in genetic disorder, chromosomal abnormalities, mutations, infectious
diseases and disease-relevant biomarkers. MicroRNAs (miRNAs) are a class of non-coding RNAs that
are widely found distributed in eukaryotes. Few miRNAs influence the nervous system development,
and nerve damage repair. Microarray approach can be utilized to understand the miRNAs involved and
their pathways in POCD development, unleashing their potential to be considered as a diagnostic
marker for POCD. This paper summarizes and identifies the studies that use microarray based approaches
for POCD analysis. Since the application of microarray in POCD is expanding, there is a
need to review the current knowledge of this approach.
A Prospective Analysis of Potential and Observed Drug-Drug Interactions, Adverse Events and its Associated Risk Factors in Hospitalized Cardiology Patients in Benin
Authors: Allabi Aurel C.E. , Tchabi Yessoufou , Hounkponou Murielle , Quenum Rebecca , Vehounkpe-Sacca Jeanne
Published: June 2020

Background & Aims:

The objective is to ascertain the pattern of potential drug-drug interactions
(pDDIs) and record any observed DDIs and adverse events (AEs) in hospitalized Beninese
cardiology patients from Sub-Saharan Africa and analyze all risk factors associated with DDIs
and AEs.

Methods:

It was a prospective study in which data including AEs were assessed from medical files
and interview of patients and their relatives. Patients who were treated with more than two drugs
and who remained in the hospital for at least 48 hours were included. A computerized database system
Pharma IAM- VIDAL version 2011 was used to identify the pattern for potential DDIs.

Results:

156 patients were included in this study. The prevalence of potential DDIs was estimated
at 93 % (145/156). Forty (5.1%) among 804 potential DDIs identified were observed clinically. The
observed DDIs were attributable to low blood pressure (27.5%), hyponatremia (22.5%), hemorrhage
(20.0%), hyperkalemia (17.5%) and nephrotoxicity (7.5%). The combination of spironolactone and
furosemide resulted in hyponatremia while the combination of enoxaparin and potassium resulted in
hyperkalemia. ACE inhibitor (or ARAII) in combination with furosemide resulted in the nephrotoxicity
cases observed. Enoxaparin, Acetyl salicylic acid, Acenocoumarol and Clopidogrel were decreasingly
involved in the pairs of drugs responsible for observed hemorrhages. 29 patients out of
156 (18.6%) had at least one AE. AEs were mainly (34.2%) of metabolic type. Severe AEs, which
represented 18.4% was mostly from nephrotoxicity and metabolic disorders. More than 14 active
substances multiplied the risk factor for AEs occurrence by 42, while more than 14 days hospitalization
increased this risk by 42.

Conclusion:

This study highlights the need to optimize treatments by strictly regulating blood pressure,
serum sodium and potassium levels, coagulation parameters and looking for clinical signs of
hemorrhage. Physician should be aware of certain drug associations that may carry a risk of severe
adverse events.

Published: June 2020

Stem cell-based therapy is one of the therapeutic options with promising results in the
treatment of diabetes. Stem cells from various sources are expanded and induced to generate the cells
capable of secreting insulin. These insulin-producing cells [IPCs] could be used as an alternative to
islets in the treatment of patients with diabetes. Soluble growth factors, small molecules, geneencoding
transcription factors, and microRNAs [miRNAs] are commonly used for the induction of
stem cell differentiation. MiRNAs are small non-coding RNAs with 21-23 nucleotides that are involved
in the regulation of gene expression by targeting multiple mRNA targets. Studies have shown
the dynamic expression of miRNAs during pancreatic development and stem cell differentiation. MiR-
7 and miR-375 are the most abundant miRNAs in pancreatic islet cells and play key roles in pancreatic
development as well as islet cell functions. Some studies have tried to use these small RNAs for the
induction of pancreatic differentiation. This review focuses on the miRNAs used in the induction of
stem cells into IPCs and discusses their functions in pancreatic β-cells.
The Influence of Endothelial Nitric Oxide Synthase (eNOS) Genetic Polymorphisms on Cholesterol Blood Levels Among Type 2 Diabetic Patients on Atorvastatin Therapy
Authors: Abdullah Sarah , Jarrar Yazun , Alhawari Hussam , Abed Eyada , Zihlif Malek
Published: June 2020

Background:

Endothelial nitric oxide synthase (eNOS) plays a major role in the response of
anti-hypercholesterol statin drugs. Genetic polymorphisms in the eNOS gene affect the activity of
eNOS thereby modulating the statin response.

Objectives:

This study investigated the influence of major functional eNOS gene polymorphisms
(rs2070744, rs1799983, and rs61722009) on the lipid profile of type 2 diabetes mellitus (T2DM) Jordanian
patients treated with atorvastatin.

Methods:

The sample comprised 103 T2DM patients who attended the diabetes clinic of Jordan University
Hospital. The T2DM patients had regularly been taking 20 mg atorvastatin. The atorvastatin
response was calculated by measuring the lipid profile before and after three months of atorvastatin
treatment. The eNOS genotypes of the subjects were analyzed using polymerase chain reaction (PCR)
followed by restriction fragment length polymorphism (RFLP) assay.

Results:

No significant association was found between eNOS genetic polymorphisms and the response
to atorvastatin (ANOVA, p > 0.05). In addition, no significant difference in the frequency of eNOS
genotypes was found between T2DM patients and healthy subjects. However, patients with eNOS
rs1799983, 4a/4a, and rs61722009 G/G genotypes showed significantly lower levels of baseline total
cholesterol (TC) and low density lipoprotein (LDL) than did patients carrying the rs1799983 4b/4b or
rs61722009 T/T genotype (p < 0.05). The eNOS rs1799983 and rs61722009 polymorphisms were in
complete linkage disequilibrium (D' = 1).

Conclusion:

Although no association was found between eNOS genetic polymorphisms and atorvastatin
response, there was a significant association between the rs1799983 and rs61722009 genotypes
and baselines levels of TC and LDL in Jordanian T2DM patients. These genetic variants affect cholesterol
levels and may play a role in the susceptibility to cardiovascular diseases in T2DM patients. Further
studies are needed to validate these findings.

Authors: Benbelaïd Fethi , Khadir Abdelmounaїm , Benziane Yacine , Benaissa Asma , Bendahou Mourad
Published: June 2020

Background:

Cistus munbyi Pomel is a well-known medicinal plant
in Western Algeria for its several applications in medicine and food. This endemic
species from North Africa is poorly studied among the genus of Cistus, which
gives the opportunity to carry out original pharmacological studies to value this
medicinal plant.

Objective:

To investigate the antioxidant and the antimicrobial activities of Cistus
munbyi, an endemic medicinal plant from Algeria.

Methods:

The antioxidant properties of C. munbyi crudes extracts were evaluated
using the DPPH radical-scavenging activity tests. While their antimicrobial activity
was studied by the agar diffusion method and MICs determination against
eighteen bacterial and fungal strains, some of which were clinical.

Results:

The obtained results showed that aqueous and ethanol extracts possess a
strong scavenging activity against DPPH radicals with EC50 values estimated at
1.12 and 8.31 μg/mL, respectively. On the other hand, extracts from C. munbyi
revealed homogeneous and good antimicrobial activity, in which the inhibition
zone diameters observed were ranging from 08 to 19 mm, and the MICs values
were included from 0.312 to 5.000 mg/mL. The aqueous extract was less active
except against Proteus mirabilis and Staphylococcus aureus.

Conclusion:

The findings of this study indicate that C. munbyipossesses a strong
antioxidant activity and an interesting antimicrobial potential, which allows justifying
its uses by the local population in several applications. Therefore, C. munbyi
could be a good source of natural antioxidants and antimicrobial agents.

Parenting Research in Indonesia: What We Have Done So Far
Authors: Kiling-Bunga Beatriks Novianti , Margiani Kristin , Kiling Indra Yohanes
Published: June 2020

Parenting is one of the most important responsibilities that someone could bear as a parent, probably the most burdensome too. Regardless, several questions are still left unanswered by Indonesian scientists, what are the field of studies related to parenting? What are the problems emanating from the practice of parenting and their solutions? What are the strategic steps one can take as psychology scientist or practitioner to improve parenting in Indonesia? This study examined the application of scoping review to provide responses for aforementioned questions. Just like the way a cartographer map an area in order to advance civilization, a scoping review is meant to enlighten future researchers with the answers on “what has been done?”. Five databases were searched in this review, 94 articles were discovered to undergo further rigorous selection, and 16 chosen articles were charted and analyzed accordingly. Finding shows that education, health, and psychology were the field of studies associated with high quality parenting research in Indonesia. Problems in child’s development caused by bad parenting attracted most researchers’ attention. Solutions provided were unique to each study’s context and hard to generalize. Finally, it is suggested that psychologists’ involvement in national parenting program is inevitable, and should start from today.
Gold Mining and Political Struggles for Access in Banyuwangi, East Java
Authors: Indah Surya Wardhani  , Devy Dhian Cahyati
Published: June 2020

This article explores how the materiality of natural resources influences social movements. Applying a relational paradigm and new materialism approach, this article explores the materiality of gold as a vital element of actor-network linkages, organisation, framing mechanisms, and recruitment. The transformation of gold from an ore into a mechanism for commodification reflects the interactions between capital holders, scientists, political actors, and legislators. This sociomaterial formation has limited residents' access to such resources as gold, water, land, wood, and clean air, and this momentum has given rise to a social movement in opposition to gold mining activities.

This article shows that social movements are not monolithic, but rather dynamic movements that consist of various actors, issues, narratives, and strategies. This study focuses on the anti-mining movement in Tumpang Pitu, Banyuwangi, East Java, and its two decades of struggle to illustrate how the formation, networking, fragmentation, and evolution of social movements is influenced by their materiality (in this case, gold). This article finds that the commodification of gold influences movements' repertoires. This offers an alternative explanation for social movements, which have long been dominated by an actor–structure approach that views social movements as linear, monolithic, and constant collective actions that respond to marginalisation and injustice.
The Precarity of Peri-urban Resistance: A Resistance to the Forced Eviction of Pasar VI Village and the Development of Kualanamu International Airport, North Sumatera
Authors: Iswan Kaputra  , Prathiwi Widyatmi Putri
Published: June 2020

In 1997, Kualanamu was chosen as the site of a new airport in North Sumatra. The central government's unilateral decision created new agrarian conflict and complicated the agrarian issues that had plagued the region since the colonial era. The accumulated conflicts and structural issues left local residents in a precarious state as they became integrated into peri-urban society. This article highlights the complexity of the conflict, the agency–institutional–structural relations that underpin it, and peri-urban resistance within the context of urbanisation and its marginalisation of rural communities.

Published: June 2020

La mezcla de analgésico, antipirético y antihistamínico de una pastilla antigripal de marca conocida fue evaluada en su capacidad de provocar daño cromosómico y citotoxicidad en sangre periférica de ratón árabe. El daño cromosómico fue evaluado utilizando la prueba de micronúcleos in vivo. El antigripal fue administrado a ratones de la línea árabe por vía oral en una dosis de 10.6 mg/Kg de peso en el curso de ocho h por tres días en un tratamiento agudo. Los cálculos del índice de toxicidad no fueron significativos estadísticamente entre los datos del grupo control negativo y los tratamientos con el antigripal. En cambio, este antigripal mostró efectos genotóxicos significativos a las 24, 48 y 72 h después de su aplicación. Este efecto puede ser causa de los componentes químicos del antigripal como son el paracetamol y la cafeína. En conclusión, la mezcla de analgésico, antipirético y antihistamínico de una pastilla antigripal no provoca daño celular pero muestra daño clastogénico durante el tratamiento agudo del antigripal en ratones de la línea árabe. El ratón Árabe mostró sensibilidad a los efectos de los agentes genotóxicos y, por tanto, este organismo debería ser incluido para estudios de genotoxicidad.

Authors: Gallego Cartagena Euler , Herrera Britto Leydis Yohana , Manjarrez Rodríguez Lena Judith , Vargas Zapata Carmiña Lucía
Published: June 2020

We studied the growth and production of pigment of microalgae Dunaliella salina cultivated in
photobioreactor multicamera oscillating outside laboratory conditions to evaluate the effect of different
concentrations of zeolite (ZC). Growth was evaluated by cell count and pigment content was performed
by spectrophotometric techniques. The results indicate that the concentration of 50 mgL-1 of ZC produced
a better stimulus on the growth of the microalga reaching maximum cell density (MDC) of 5.51 ±0.45 x 106
celmL-1, growth rate (μ) 0.37 ±0.03 divday-1 and duplication time (Td) of 1.87 ±0.02 days. Likewise,
produced a greater increase in the total chlorophyll and carotenoids in the logarithmic phase of values
15.554 ±0.77 and 0.50 ±0.01 mgmL-1, respectively. Chloroplastic pigments concentration per volume of
culture has a significant correlation with maximum cell density of D. salina treatments based on zeolite at
all stages of growth with rMDC, chla.tot= 0.89 y una rMDC, carot.tot=0.926 at a level of significance (p <0.01). The
results demonstrated the feasibility of using this product as a suitable substrate for the growth of the
microalga, being an innovative alternative and less costly to obtain significant metabolites.
POPULATION ASPECTS OF CROCODYLUS ACUTUS (REPTILIA: CROCODYLIDAE) IN THE ESTUARY EL SALADO, PUERTO VALLARTA JALISCO, MEXICO
Authors: Rubio-Miranda Javier Efraín
Published: June 2020

A population of C. acutus was studied in the Natural Protected Area “Estero el Salado” in Puerto Vallarta, Jalisco, México, among november of 2015 and september of 2016. The population abundance was evaluated and the age structure, mortality rate and growth rate were analized. Five samplings were performed in November, December, March, April and September, in order to carry on the species monitoring, finding an abundance of 15.74 ind/km SD ± 6.65, and the neonates population’s mortality rate, which showed constant values, increasing the neonates survivorship. As well the age structure was analized and it was consisted of 62.5% neonates, 28.5 juveniles and 9% sub-adults, without presence of adults, subsequently catches of the organisms were made in order to measure the total lenght of crocodiles, and thereby obtain the growth rate, wich was between 0.12 y 0.17 cm/day. This is the first study that analized the mortality rate of C. acutus neonates in a mangrove swamp, therefore this information could be used to perform better conservation strategies.
EFFECT OF THE SYMBIOSIS BETWEEN LOLIUM MULTIFLORUM AND THE ENDOPHYTE EPICHLOË OCCULTANS ON NUTRITIONAL QUALITY OF PASTURE IN BIOSOLIDS´ AMENDED SOIL
Authors: Torri Silvana Irene , Puelles María Mabel , De las Nieves Ovejero Alexis Magali
Published: June 2020

Biosolids have a high content of stable organic matter, which may be used for the remediation of marginal non-agricultural soils used for pasture production. In Argentina, the aerial biomass of Lolium multiflorum Lam., species is highly infected with the endophyte Epichloë occultans. Endophytes establish a symbiotic relationship with host plants, providing protection and resistance against different stress factors. Since land application of biosolids may rise plant stress, the objective of this work was to analyze the growth and concentration of copper (Cu) and zinc (Zn) in aerial biomass of L. multiflorum in symbiosis (or not) with the endophyte E. occultans on a sandy textured soil amended with biosolids. The association of L multiflorum with the endophyte produced an increase in aerial biomass only in the biosolids´ amended soil. However, the presence of the endophyte did not modify the concentration of Cu or Zn in the aerial biomass of the pasture under the experimental conditions.

The growth of organisms is accompanied by changes in proportion and size, and it is known as relative or allometric growth. C. crassum is one of the largest crab species it inhabits mangrove forests in the Eastern tropical Pacific, however, the data of this specie is deficient and limited to a few records. Therefore, the aim of this work was to estimate the growth of C. crassum in El Salado stream, Puerto Vallarta, Jalisco, Mexico. A total of 252 organisms were captured in the rainy season, which were marked and released after assessments. The Huxley equation was used to determine allometry and to estimate the condition factor (K) and the growth rate. The sex ratio was 1:1.72, favoring females. The range of the condition factor in females was between 0.02 and 0.06 g/cm3. In ovigerous females the K mínimum value was 0.03 and the maximum value was 0.08 g/cm3; for males the K minimum was 0.03 and the maximum was 0.14 g/cm3. A K=0.88 was obtained and Lmax=95.1 mm. There were no significant differences in CA between sexes, neither in PO. While differences could be observed in LQ and AQ between sexes. It was concluded that C. crassum growth is similar to another gecarcinid species in El Salado. Males reach larger sizes than females and the condition factor is similar between males and non-ovigerous females, but there are significant differences between the condition factor in females and ovigerous females.

One of the ways to reduce inappropriate management of hives and monitor bee health is to send notifications/alerts about the data collected through sensors. This study presents  BeeNotified!, a solution for sending notifications through Telegram, e-mail, and SMS. The notifications warn about the level of temperature, humidity, sound, carbon dioxide, oxygen, hive weight and delay in data gathering. From this data, researchers and beekeepers can be informed and make changes in the locations of the hives, avoiding catastrophes and possible diseases. The results obtained with the processing time in the sending of messages showed that the messages sent via SMS and Telegram have a shorter processing time compared to the sending via e-mail. In regards to sending notifications according to user preferences, all notifications were sent correctly.
WebGIS development for base flow separation and recharge estimation
Authors: Bortolin Taison Anderson , Dos Santos Lucas Moraes , Da Silva Adriano Gomes , Schneider Vania Elisabete
Published: June 2020

The basic flow rate is characterized by an important hydrological component being responsible for the estimation of the water recharge. Due to the difficulty of measurement, mathematical methods are used to calculate the flow separation. However, when hydrographic analysis is based on long historical series, the use of these methods becomes impracticable, making it necessary to use computational resources. A WebGIS (Web Geographical Information System) was developed for data selection and calculation of base flow separation, based on hydrological data from fluviometric stations located in the Taquari-Antas basin, located in the state of Rio Grande do Sul. A modified version of the Unified Process was used as a software development methodology. We used the MVC software architecture standard and the programming languages PHP 7.0, HTML5, JS and CSS3 for programmatic development of the constituent layers of the system. The hydrological data comes from the HIDROWEB portal, part of the National Information System on Water Resources (SNIRH), with hydrological information collected by the National Hydrometeorological Network (RHN) coordinated by the National Water Agency (ANA). The system facilitates the use of remote and distributed hydrological data, shared over the Internet, for various hydrological analyzes.
DenseNet-DC: Optimizing DenseNet Parameters Through Feature Map Generation Control
Authors: Tavares da Silva Andre , Roberto Siebert Cristiano
Published: June 2020

Convolutional Neural Networks still suffer from the need for great computational power, oftenrestricting their use on various platforms. Therefore, we propose a new optimization method made for DenseNet, a convolutional neural network that has the characteristic of being completely connected. The objective of the method is to control the generation of the characteristic maps in relation to the moment the network is in, aiming to reduce the size of the network with the minimum of loss in accuracy. This control occurs reducing the number of feature maps through the addition of a new parameter called the Decrease Control or dc value, where the decrease occurs from half of the layers. In order to validate the behavior of the proposed model, experiments were performed using different image bases: MNIST, Fashion-MNIST, CIFAR-10, CIFAR-100, CALTECH-101, Cats vs Dogs and TinyImageNet. Some of the results achieved were: for the MNIST and Fashion-MNIST base, there was 43% parameter reduction. For the CIFAR-10 base achieved a 44% reduction in network parameters, while in base CIFAR-100 the parameter reduction are 43%. In the CALTECH-101 base the parameter optimization was 35%, while the Cats vs Dogs optimized 30% of model parameters. Finally, the TinyImageNet base was reduced 31% of the parameters.
Experiments on Model-Based Software Energy Consumption Analysis Involving Sorting Algorithms

Published: June 2020

Although energy has become an important aspect in software development, little support exists for creating energy-efficient programs. One reason for that is the lack of abstractions and tools to enable the analysis of relevant properties involving energy consumption. This paper presents the results of some experiments involving the gathering, modelling, and analysis of energy-related information, in particular, the costs of executing certain parts of a software. We combine some existing free and open-source tools to carry out the experiments, extending one of them to handle energy information. Our experiments consider a comparison of energy consumption of Java implementations of the Bubble Sort, Insertion Sort and Selection Sort algorithms using different data structures. We show how to combine an energy measurement tool and a model analysis tool to carry such a comparison. Based on this support and on our experiments, we believe this is a first step to allow developers to start creating more energy-efficient software.
Automatic identification of knowledge related to dengue cases in the state of Piauí in public databases using Filtered-Association Rules Networks

Published: June 2020

Dengue is an endemic disease in Brazil since the 1980s and since 1996 in Piau ́ı. The number of cases increases each year, with the incidence of more severe symptoms. This research aimed to evaluate the use of an automatic knowledge identification technique in factors related to the number of dengue occurrences. We built a dataset formed by data available in the Information System for Notifiable Diseases (SINAN) and meteorological data of the municipalities of the coastal plain of Piau ́ı. The technique used was that of Filtered Association Rules Networks, which allows visual analysis of knowledge through the use of network structures and rules filtering. As a main result, we confirmed the understanding that the most significant number of cases occurs in May, as it is the moment when the rainfall indexes are decreasing, besides that socio-cultural and race factors do not interfere in the identification of the population of higher risk. This research presents the innovation of the use of a computational technique of automatic knowledge discovery that can assist in the elaboration of prevention actions by epidemiological surveillance.
Prácticas pedagógicas apoyadas por tecnologías móviles: oportunidades para potenciar el aprendizaje de la población estudiantil
Authors: Villalobos-García Melissa , Núñéz-Sosa Olmer
Published: June 2020

Con el fin de identificar aspectos clave para potenciar el aprovechamiento de las tecnologías móviles en los procesos de aprendizaje, se plantea un estudio de alcance descriptivo en el que se comparan condiciones socioeconómicas, educativas y de aprovechamiento de estos recursos en dos poblaciones de estudiantes de secundaria: participantes con al menos dos años de experiencia en el uso de tecnologías móviles en clase y participantes que no contaban con dicha experiencia. Desde un enfoque comparativo entre las poblaciones, se identificó que las personas estudiantes que reciben apoyo pedagógico para incorporar tecnologías móviles en sus procesos de aprendizaje tienden a considerarse usuarios más competentes de dichos recursos; muestran mayor repertorio de conocimiento sobre herramientas útiles en el ámbito educativo, y evidencian mejores condiciones para usar de manera segura espacios de ocio como las redes sociales. Se concluye que una de las mayores oportunidades para potenciar el aprovechamiento de las tecnologías móviles en los procesos de aprendizaje se relaciona con el rol que tienen sus docentes en ello, por lo cual favorecer el desarrollo de apropiación tecnológica en la población docente resulta clave dentro de este tipo de propuestas educativas.

Authors: Víquez-Duarte Maikol , Orozco-Delgado Víctor
Published: June 2020

Mediante una reconstrucción histórica con consideraciones jurídicas inherentes a la realidad de los responsables de ejecutar la administración pública costarricense, se busca describir de forma práctica la realidad de la organización del personal administrativo de una entidad pública, la cual cuenta con una de las más grandes planillas a nivel centroamericano y se enfrenta al desafío de atender la que parece una interminable gestión: desarrollar infraestructura educativa en el país. Hecha la revisión documental correspondiente y el análisis de la misma, se evidencia una clara intención del Ministerio de Educación Pública de buscar alternativas distintas para la atención de la problemática relacionada con la construcción y mantenimiento de obra; sin embargo, la problemática continúa vigente, pese a que, a partir del año 2012, se acudió a instrumentos alternativos para la construcción de edificios escolares, como es la constitución de un fideicomiso para el desarrollo de infraestructura educativa, el cual es un importante esfuerzo ministerial, pero como primera experiencia y al estar en cumplimiento de su periodo de ejecución, los resultados aún no han sido los esperados, básicamente por el plazo de entrega de obras y por el incremento en los costos inicialmente proyectados.
Credit risk management in bank: Impacts of IFRS 9 and Basel 3
Authors: Porretta Pasqualina , Letizia Aldo , Santoboni Fabrizio
Published: June 2020

The expected loss approach (ECL) defined by IFRS 9 replaced the old incurred loss approach (IAS 39) in the international accounting standard setter. In Europe, the IFRS 9 are accompanied by new regulatory frameworks (BCBS), opinion, technical standards (EBA) which do not always provide the same methodological and operational implications of the accounting standard setter. Many aspects of IFRS 9 have been studied, but this paper analyzes its interdependencies and overlaps with the credit risk framework for financial intermediaries (also Basel 3). Using a case study, the purpose of this paper is to investigate the ECL, its main impacts on coverage ratio of a loan’s portfolio. The main findings are: usually, the rules laid down for Stage 1 of IFRS 9 do not reduce the excess coverage produced on a portfolio in bonis; in the presence of impaired loans IAS 39 generates a lack of funds; the lifetime ECL (Stage 2 of IFRS 9) imposes excess of provisions because it does not consider the effect of coverage produced by expected premiums; for loan portfolios with short repayment times, the excess of provisions produced by IFRS 9 compensates the lack of coverage of the capital requirement. From the academic research perspective, this paper contributes to the literature on ECL model in several ways. First, it adds knowledge to the research on the relationship between Credit Risk Management framework and accounting standard IFRS 9. Second, it also links our findings related to ECL approach with potential implications for the financial sector, policymakers and regulators.
