Published: February 2020

Background Spinal anesthesia-induced maternal hypotension is the most frequent complication associated with maternal morbidity and mortality during cesarean section. The aim of this study was to compare the incidence and magnitude of hemodynamic changes in preeclamptic and non-preeclamptic parturients undergone cesarean section under spinal anesthesia. Method A prospective cohort study was conducted from February to May 2019 in University of Gondar comprehensive specialized hospital. A total of 122 ASA II and ASA III parturients were recruited consecutively and assigned to two groups (81non-preeclamptics, and 41 preeclamptics). The data analysis was done by SPSS version 22 statistical software. The data were tested for normality with Shapiro Wilk U-test and normally distributed data were compared by using the independent student’s t-test. Whereas non-normally distributed data were compared using the Mann-Whitney U- test. Fisher’s exact test was used for intergroup comparison of proportion. All P values <0.05 were considered statistically significant. Result The incidence of spinal anesthesia-induced hypotension was higher in non-preeclamptic parturients than preeclamptic parturients (55.6% vs. 34.1%, respectively) and the degree of blood pressure drop was significantly greater in the non-preeclamptic parturients compared to those with preeclampsia; As well intraoperative fluid consumption was significantly greater in the non-preeclamptics parturients compared to those with preeclamptics. Conclusion The incidence and magnitude of spinal anesthesia-induced hypotension in parturients undergone cesarean section were less in preeclamptic parturients than in non-preeclamptic parturients. Therefore, don’t deny spinal anesthesia for preeclamptic parturients due to fear of profound hypotension, unless there is a contraindication for spinal anesthesia.

Authors: Firoozeh Farzaneh , Omidi Mitra , Saffari Mahmood , Sedaghat Hossein , Zibaei Mohammad
Published: February 2020

Background: The global spread of methicillin-resistant Staphylococcus aureus (MRSA) infections necessitates the use of validated methods for the identification and typing of this bacterium. This study aimed to determine the distribution of main molecular types of MRSA strain circulating among hospitalized patients in teaching hospitals in Isfahan and Kashan. Methods: A total of 146 Staphylococcus aureus strains were isolated from patients in four teaching hospitals in Isfahan and Kashan during June 2017 to September 2018. The antibiotic resistance patterns of Staphylococcus aureus strains were performed by disc diffusion method. The MRSA strains were identified phenotypically and confirmed by PCR assay. The prevalence of microbial surface components recognizing adhesive matrix molecules (MSCRAMMs) genes among MRSA strains was evaluated by multiplex PCR. The genotypes of MRSA strains were determined by multi-locus sequence type and SCC mec typing. Results: Of 146 Staphylococcus aureus isolates 24 (16.4%) isolates identified as MRSA strains. According to antibiotic susceptibility testing the highest resistance rates were seen to erythromycin, cefoxitin and clindamycin. All of Staphylococcus aureus isolates were sensitive to vancomycin whereas 3 (2.1%) isolates were resistant to linezolid. Three different SCC mec types were obtained among MRSA strains including 16 (66.7%) SCC mec type V, 3 (12.5%) SCC mec type III and 5 (20.8%) SCC mec type II. Of 24 MRSA isolates 20 (83.3%) carried MSCRAMMs genes including eno (70.8%), fib (54.1%) , cna (25.0%), fnbB (16.6%) , ebps 5 (20.8%), and fnbA , bbp and clfA genes were not detected. MLST analysis revealed 11 sequence types among MRSA isolates as follows: ST239, ST239, ST291, ST22, ST861, ST 889, ST8, ST59, ST343, ST772, ST6 and ST1465. Also seven MLST-based clonal complexes (CCs) were identified among MRSA strains including: CC8, CC7, CC398, CC59, CC22, CC1 and CC5. Conclusions: A relatively high diversity was found in MRSA genotypes in Kashan and Isfahan hospitals, and seven clonal complexes were identified. Pandemic MRSA clones including CC8 and CC22 were the most prevalent clones and the novel ST types including ST1465, ST861, ST 889 and ST772 are reported for the first time in Iran in the present study. In addition the high prevalence of MSCRAMMs genes in MRSA isolates demonstrates the high potential of these strains for pathogenicity.
First-order transition in a model of prestige bias
Authors: Skinner Brian
Published: February 2020

One of the major benefits of belonging to a prestigious group is that it affects the way you are viewed by others. Here I use a simple mathematical model to explore the implications of this ``prestige bias'' when candidates undergo repeated rounds of evaluation. In the model, candidates who are evaluated most highly are admitted to a ``prestige class'', and their membership biases future rounds of evaluation in their favor. I use the language of Bayesian inference to describe this bias, and show that it can lead to a runaway effect in which the weight given to the prior expectation associated with a candidate's class becomes stronger with each round. Most dramatically, the strength of the prestige bias after many rounds undergoes a first-order transition as a function of the precision of the examination on which the evaluation is based.
Atenolol removal by nanofiltration: a case-specific mass transfer correlation
Authors: Giacobbo Alexandre , Soares Elisa Veridiani , Bernardes Andréa Moura , Rosa Maria João , de Pinho Maria Norberta
Published: February 2020

Concentration polarization is a phenomenon inherent to membrane separation operations and as a precursor of membrane fouling is frequently related to the decrease in the performance of these operations. In the present work, a case-specific mass transfer correlation was developed to assess the concentration polarization when nanofiltration, in different operating conditions, was applied to treat a pharmaceutical wastewater containing atenolol. NF runs with two membranes, two atenolol concentrations and three feed circulating velocities were conducted, and the corresponding experimental mass transfer coefficients were determined using film theory to describe the concentration polarization phenomenon. Higher velocities led to higher mass transfer coefficients and, consequently, lower concentration polarization. These mass transfer coefficients were correlated with the circulating velocity (Re), the solute diffusivity (Sc) and the membrane permeability (LP+) (the membrane is a permeable interface with effect on the concentration profiles developed from the interface towards the bulk feed), yielding the following correlation Sh = 1.98 × 104Re0.5Sc0.33LP+0.32. The good agreement between the calculated and the experimental results makes this correlation a valuable tool for water practitioners to predict and control the concentration polarization during atenolol-rich wastewater treatment by nanofiltration, thereby increasing its productivity and selectivity.
The Emerging Role of Atrial Natriuretic Peptide in Psychiatry
Authors: Marazziti Donatella , Barberi Filippo Maria , Mucci Federico , Maglio Alessandra , Dell’Oste Valerio , Dell’Osso Liliana
Published: February 2020

Introduction:

Atrial natriuretic peptide (ANP), composed by 28 amino-acids, is well
known to modulate fluid and electrolyte homeostasis, the hypothalamic-pituitary-adrenal (HPA) axis
activity and the immune system. Since ANP is produced in both heart and in the central nervous system
(CNS), in the last years, increasing attention has been devoted to its possible role in neuropsychiatric
disorders. Indeed, scattered data would indicate its possible role in anxiety, major depression,
addictive behaviors, post-traumatic stress disorder and other stress-related disorders. Further, ANP
has been hypothesized to represent one of the factors linking depression to cardiovascular health and
the immune system.

Aims:

Given the paucity of available information, the aim of this paper was to review the current
literature on the role of ANP in the CNS and in the pathophysiology of different neuropsychiatric and
stress-related conditions.

Discussion:

Supporting data on ANP in psychiatric disorders are still limited to animal studies, or to
a few “real” findings in patients gathered some decades ago that should be replicated in larger clinical
samples.

Conclusions:

Further studies are necessary to understand the possible implications of ANP in neuropsychiatry,
because potentially it might represent a new way for innovative psychopharmacological
treatments in different conditions, all underlaid by hyperactive HPA axis.
An Efficient Procedure for the Synthesis of 21-Acetoxypregna-1,4,9(11),16- tetraene-3,20-dione
Authors: Huy Luu D. , Diep Nguyen T. , Vu Tran K. , Savinova Tatiana S. , Donova Marina V.
Published: February 2020

Background:

Halogenated corticosteroids are widely used in medicine, and the global
need of these steroidal APIs is estimated to be 40 – 70 tons, annually. Vietnam currently imports
the pharmaceutical compounds up to 90%, in particular 100% of steroidal drugs. Currently,
industrial production is based on the chemical syntheses of corticosteroids from either 16-
dehydropregnenolone acetate (obtained from diosgenin) or androstenedione (obtained from
phytosterol). The development of shorter synthetic schemes and more economically feasible
technologies is of great significance. Introduction of 1(2)-double bond at the final stages of the
corticosteroids synthesis results inpoor yield. 21-Acetoxypregna-1,4,9(11),16-tetraene-3,20-dione
(tetraene acetate) is a key intermediate in the synthesis of highly active halogenated corticosteroids
such as dexamethasone and other halogenated corticosteroids. 21-acetoxypregna-1,4,9(11),16-
tetraene-3,20-dione is a key intermediate in the synthesis of dexamethasone from the readily
available and cheap 9α-hydroxyandrost-4-ene-3,17-dione.

Objective:

The purpose of this study was the development of an efficient and shorter procedure for
the synthesis of 21-acetoxypregna-1,4,9(11),16-tetraene-3,20-dione from 9α-hydroxyandrostenedione,
which is a product of a bio-oxidative degradation of the side chain of phytosterols.

Methods:

Pregnane side chain was constructed using cyanohydrin method. For 1(2)-
dehydrogenation, selene dioxide was applied for the introduction of Δ1(2)-double bond. Other
stages of the synthesis were epimerization, Stork’s iodination procedure and dehydration.

Result:

21-Acetoxypregna-1,4,9(11),16-tetraene-3,20-dione was prepared from 9α-
hydroxyandrostenedione in yield more than 46%.

Conclusion:

An efficient and practically feasible procedure for the synthesis of 21-acetoxypregna-
1,4,9(11),16-tetraene-3,20-dione from 9α-hydroxyandrostenedione, a key intermediate for the
synthesis of 9-haloidated corticoids, has been developed. The procedure can be applied for the
production of value-added 9-haloidated corticoids.
Physico-chemical Characterization of Hydrochloric Acid-treated Kaolin Clay: An Industry Approach as a Potential Catalyst
Authors: Kumar Awinash , Lingfa Pradip
Published: February 2020

Aim and Objective:

This study explains the FT-IR, XRD, XRF, SEM/EDX, TGA, and
DSC/DTA characterization of commercially available kaolin clay. The objective of this paper is to
explore the prominent utilization of kandites clay and useful chemical aspects for the modification
of kaolin clay minerals.

Materials and Methods:

The untreated kaolin sample has been procured in this experimental work
from AksharChem, Gujrat, India. The kaolin clay was treated with 4M hydrochloric acid. FT-IR,
XRD, XRF, SEM/EDX, TGA, and DSC/DTA characterization methods have been used.

Results:

Loss on ignition was found at 10.89%. The fingerprint region of the acid-treated sample
has broad and more bending vibrations than untreated samples. The high weight percentage of Ti
and CaCO3 were spotted in the scanning electron micrograph by both atomic % and weight %. The
FT-IR revealed the functional group of Al-O, A1-OH, and Si-O.

Conclusion:

The morphology indicates that the presences of large particles are in the form of
agglomerates. It was found that impurity like scandium vanished and manganese traced by the
same atomic % 0.01 of zinc which had no presence after acid treatment. Thermogravimetric
analysis indicates the sharp increments in heat flow in-between temperatures 0°C to 200°C and
consequently increments in between 500°C to 550°C, a suitable range for the pyrolysis. Low
amount of alumina and high amount of silica has been found out. TGA and DTA analysis satisfy
the waste plastic valorization temperature ranges.
The Effect of Skin Contact on Maternal-infant Attachment Behaviors in Emotional, Proximity-seeking, and Caretaking Dimensions in Planned and Unplanned Pregnancies in 2017, Iran: A Research
Authors: Eslaminia Tahere , Kaviani Maasumeh , Akbarzadeh Marzieh
Published: February 2020

Background:

Unplanned pregnancy is a potential danger for women’s lives in the reproduction
ages.

Objective:

The present study aimed to compare planned and unplanned pregnancies regarding the
maternal-infant attachment behaviors in emotional, proximity-seeking, and caretaking dimensions.

Methods:

The present analytical case-control study was conducted on 140 women who had given
birth to their children in the hospitals affiliated to Shiraz University of Medical Sciences in 2017.
The participants were divided into planned and unplanned pregnancy groups. Within the first hour
and 24 hours after birth, the babies were put naked in skin-to-skin contact with their mothers for 15
minutes and the study questionnaire was completed. The data were collected using the Avant checklist.
P<0.05 was considered to be statistically significant.

Results:

The mean score of attachment in the early hours was 84.22±12.59 in the planned pregnancy
group and 74.28±15.81 in the unplanned pregnancy group, and the difference was statistically
significant (p<0.001). However, no significant difference was observed between the two
groups in this regard after 24 hours (p=0.122). Additionally, the results revealed a significant difference
between the two groups concerning emotional (p<0.001) and caretaking (p=0.007) behaviors.
However, no significant difference was found between the two groups regarding the three behaviors
after 24 hours. Emotional (talking and smiling, p=0.001), proximity-seeking (circling one’s arms
around the baby, p=0.001), and caretaking (paying attention to the baby, p=0.001) behaviors were
significantly more observed in the two groups in the early hours and the first 24 hours.

Conclusions:

Mother’s skin-to-skin contact with her baby during lactation increased attachment in
unplanned pregnancies after 24 hours.
Anti-tumorigenic Efficacy of Tangeretin in Liver Cancer – An In Silico Approach
Authors: P. Sangavi , K. Langeswaran
Published: February 2020

Background:

Liver cancer is otherwise known as Hepatic cancer which originated from
the liver. Hepatocellular carcinoma (HCC) is the common primary Liver cancer and is one of the
emerging problems worldwide. Very few treatments are available to treat HCC because the molecular
mechanism and other HCC mechanisms are still unclear. Cyclooxygenase 2 (COX-2), one of the
most promising targets for Hepatocellular Carcinoma, is one of the dimeric enzymes which convert
Arachidonic acid into Prostaglandin H2 in the step of Prostaglandin biosynthesis. Several natural
bioactive compounds are involved in the treatment of various types of cancers. Tangeretin, a natural
polymethoxyflavone present in the peel of citrus fruits, acts as an anti-oxidant modulator and anticancerous.

Objective:

The main objective of this study is to find a suitable inhibitor for Hepatocellular Carcinoma.

Methods:

Computational approaches like molecular docking and molecular dynamics were performed
to identify the potential inhibitor for Hepatocellular Carcinoma.

Results:

In this study, COX-2 was considered as a potential target for Hepatocellular Carcinoma
which was examined with Tangeretin.

Conclusion:

Tangeretin was screened against C0X-2 which includes Molecular Docking, DFT analysis,
ADMET prediction, and Molecular Dynamics simulation. Tangeretin had good docking scores,
fulfilled the pharmacological properties through ADMET prediction, and the Protein-Ligand complex
had good stability in Molecular Dynamics simulation.

Published: February 2020

Background:

The current research work reports an investigation of the effects of employing CuO and TiO2 nanoparticles as potential additives to refinery (petroleum) diesel fuel, in order to reduce the emissions of combustion process as well as to enhance the combustion process.

Methods:

Nanodiesel samples were prepared with various concentrations (50 ppm, 100 ppm, 200 ppm, 300 ppm). The experimental work was conducted using a four stroke diesel engine with a single cylinder at various loads in order to accurately determine the influence of nanoparticles on combustion process. The experimental readings were measured at two conditions, cold start and hot start relative to the engine.

Results:

It was clearly observed that the nanodiesel fuels have significantly reduced CO, CO2, NO, unburned HC, and enhanced the engine performance. According to the experimental results the 100 ppm TiO2 and 200 ppm CuO nanodiesel have showed almost the highest performance and lowest emissions comparable to neat diesel fuel and other nanodiesel samples. Owing to 100 ppm TiO2 on hot start conditions, it was found that the CO, CO2, NO, unburnt HC, exhaust temperature, and BSFC have been reduced by 41.4%, 37 %, 38.3%, 81%, 4.9%, and 20.5% respectively at maximum load. Meanwhile, the brake power, RPM and thermal efficiency have increased by 1.5%, 1% and 2.65% respectively.

Conclusion:

Eventually the stability of nanodiesel fuels were investigated. Accordingly, the stability of 100 ppm TiO2 and for 200 ppm CuO are 7 days and 3 days.
The Multiple Sclerosis Health Resource Utilization Survey (MS-HRS): Development and Validation Study
Authors: Ness Nils-Henning , Haase Rocco , Kern Raimar , Schriefer Dirk , Ettle Benjamin , Cornelissen Christian , Akguen Katja , Ziemssen Tjalf
Published: February 2020

Background

Survey-based studies are frequently used to describe the economic impact of multiple sclerosis (MS). However, there is no validated health resource survey available, preventing comparison of study results and meaningful conclusions regarding the efficiency of long-term treatments.

Objective

The aim of this study was to develop and validate a tablet- and paper-based MS health resource utilization survey.

Methods

We developed and validated the Multiple Sclerosis Health Resource Utilization Survey (MS-HRS), consisting of 24 cost items for paper and tablet users. Data for validation came from two large German observational studies. Survey practicability was assessed according to the response rate. Reliability was described using test-retest reliability as well as Guttman lambda. Construct validity was assessed as convergent and discriminant validity via correlations with associated patient-reported outcomes and known-group analyses.

Results

In total, 2207 out of 2388 (response rate: 92.4%) patients completed the survey and were included to determine psychometric properties. The test-retest reliability had an intraclass correlation coefficient of 0.828 over a course of 3 months. Convergent validity analyses showed that total costs correlated positively with increased disability (r=0.411, P<.001). For discriminant validity, correlations of total costs with the Treatment Satisfaction Questionnaire for Medication ranged from −0.006 (convenience) to −0.216 (effectiveness). The mean annual cost was €28,203 (SD €14,808) (US $39,203; SD US $20,583) with disease-modifying therapies.

Conclusions

The MS-HRS is a multilingual, reliable, valid, electronically available, and easy-to-administer questionnaire providing a holistic cross-sectional and longitudinal assessment of resource utilization in patients with MS.
Digital Care for Chronic Musculoskeletal Pain: 10,000 Participant Longitudinal Cohort Study (Preprint)
Authors: Bailey Jeannie F , Agarwal Vibhu , Zheng Patricia , Smuck Matthew , Fredericson Michael , Kennedy David J , Krauss Jeffrey
Published: February 2020

BACKGROUND

Chronic musculoskeletal pain has a vast global prevalence and economic burden. Conservative therapies are universally recommended but require patient engagement and self-management to be effective.

OBJECTIVE

This study aimed to evaluate the efficacy of a 12-week digital care program (DCP) in a large population of patients with chronic knee and back pain.

METHODS

A longitudinal observational study was conducted using a remote DCP available through a mobile app. Subjects participated in a 12-week multimodal DCP incorporating education, sensor-guided exercise therapy (ET), and behavioral health support with 1-on-1 remote health coaching. The primary outcome was pain measured by the visual analog scale (VAS). Secondary measures included engagement levels, program completion, program satisfaction, condition-specific pain measures, depression, anxiety, and work productivity.

RESULTS

A total of 10,264 adults with either knee (n=3796) or low back (n=6468) pain for at least three months were included in the study. Participants experienced a 68.45% average improvement in VAS pain between baseline intake and 12 weeks. In all, 73.04% (7497/10,264) participants completed the DCP into the final month. In total, 78.60% (5893/7497) of program completers (7144/10,264, 69.60% of all participants) achieved minimally important change in pain. Furthermore, the number of ET sessions and coaching interactions were both positively associated with improvement in pain, suggesting that the amount of engagement influenced outcomes. Secondary outcomes included a 57.9% and 58.3% decrease in depression and anxiety scores, respectively, and 61.5% improvement in work productivity. Finally, 3 distinct clusters of pain response trajectories were identified, which could be predicted with a mean 76% accuracy using baseline measures.

CONCLUSIONS

These results support the efficacy and scalability of a DCP for chronic low back and knee pain in a large, diverse, real-world population. Participants demonstrated high completion and engagement rates and a significant positive relationship between engagement and pain reduction was identified, a finding that has not been previously demonstrated in a DCP. Furthermore, the large sample size allowed for the identification of distinct pain response subgroups, which may prove beneficial in predicting recovery and tailoring future interventions. This is the first longitudinal digital health study to analyze pain outcomes in a sample of this magnitude, and it supports the prospect for DCPs to serve the overwhelming number of musculoskeletal pain sufferers worldwide.
Antifascismo, revolución y Guerra Fría en México: la revista América, 1940-1960
Authors: Nállim Jorge A.
Published: February 2020

El artículo analiza la revista América en 1940-1960 como un espacio político-cultural privilegiado para el estudio de procesos históricos nacionales, regionales y transnacionales. Nacida de la confluencia de grupos vinculados al estado revolucionario mexicano, la izquierda y el exilio español en México, delimitó un programa original en defensa de la Revolución Mexicana, el antifascismo, los aliados en la Segunda Guerra Mundial y el exilio republicano español. Eventualmente, en el período de post-guerra y en un proceso de continuidades y rupturas, mantuvo su firme adhesión gobierno y partido revolucionarios, dio mayor cabida a temas culturales y artísticos y se vinculó a grupos locales e internacionales relacionados con la Guerra Fría cultural a favor de Estados Unidos. El análisis de los grupos, ideas y transformaciones de América permite, así, identificar aspectos relevantes de la trama social, política e ideológica detrás del mundo cultural mexicano de la época.The article analyzes the magazine América in 1940-1960 as a privileged political and cultural space for studying national and transnational historical processes. Born out of the convergence of groups linked to the Mexican revolutionary state, the left, and the Spanish exile in Mexico, it originally defined a program in defense of the Mexican Revolution, antifascism, the Allies in the Second World War, and the Spanish Republican exile. Eventually, and in a process combining continuities and changes in the post-war period, it kept its firm support for the revolutionary government and party while it opened its pages to cultural and artistic contributions and established relations with local and international groups tied to the United States-led cultural Cold War. Thus, the analysis of America’s groups, ideas, and transformations makes it possible to identify relevant aspects of the social, political, and ideological network behind the Mexican cultural world of the time.
Osobennosti kul'turnoy diplomatii Italii na sovremennom etape
Authors: Bokeriya Svetlana Aleksandrovna , Danilov Valerij Vitalevich
Published: February 2020

The article analyzes the cultural policy of Italy, which is one of the key soft power instruments of the country, along with public diplomacy, the Italian language, education and scientific activities, through the prism of the cultural strategy of the EU. Despite the presence of a large number of articles on soft power implementation, this issue remains insufficiently covered today, since the concept of soft power emerged at the end of the 20th century in the framework of the American international relations school (J. Nye) and the majority of academic foreign papers are still devoted to the American soft power model. It is revealed that scientific community paid not enough attention to the Italian soft power phenomenon. The author’s goal is to analyze the cultural model of Italy, used as one of soft power component. According to the results of the structural, comparative and institutional analysis, fundamental problems in the development of the Italian cultural model were identified, as well as the links between the successful adoption of cultural diplomacy and economic crisis. The governmental initiatives in Italy in realization of cultural diplomacy and the EU cultural strategy are thoroughly reviewed. The analysis of the activities of specialized government institutions responsible for the cultural promotion of the country and the Italian language abroad is carried out. The soft power rankings, reflecting the effectiveness of cultural policy, in particular, Anholt-GfK Nation Brands Index and The Soft Power 30 are being analyzed. Measures to ensure the efficient use of the soft power resources in Italy are proposed. They are mostly aimed at combining the activities of existing institutions and forming an integrated strategy for popularizing, financing and broadening soft power components both within the state and foreign policy strategy.
Turkey and Greece: Political and Economic Relations within the Conflict Circumstances (1999-2017)
Authors: Atrashkevich Alexandra Nikolaevna
Published: February 2020

The author distinguishes four stages of bilateral relations between Turkey and Greece in 1999-2017: 1) the “thaw” of 1999-2003; 2) the period of the growing cooperation with attempts to resolve the Cyprus issue in 2003-2009; 3) the next one encompassing 2009-2014, when efforts to build a contractual-cum-institutional basis for the expansion of relations took place: 4) and that of worsening the political relations in 2014-2017. After analyzing these phases, the author concludes that during the whole of study period, Ankara and Athens failed to improve their bilateral relations to the point of overcoming negative historical accounts and ethnic stereotypes. Despite the constant increase of the trade volume, at the political level there were a number of problems hindering the intensification of the bilateral dialogue. The main ones are the Cyprus issue and Turkey’s claims on the Greek continental shelf. The solution of these issues is obligatory for the further development of bilateral political relations as well as for the maintenance of the security in the region.

Published: February 2020

This research is motivated by one of the government programs namely Strengthening Character Education (PPK), especially in elementary schools to produce a golden generation in 2045. The characters studied include 5 main characters namely religious, nationalist, integrity, independent, and mutual cooperation. This research will be conducted at the SD Laboratorium UPI Tasikmalaya. In addition to instilling character education in daily activities, in this school, there is also a love for local wisdom. The research method used is a descriptive qualitative method. Based on the results of the study, inculcation of character education based on local wisdom in the SD Laboratorium UPI Tasikmalaya was implemented through habituation and through classroom learning. The habituation is done not only in the classroom or in the school environment, but habituation also involves students' parents at home. In the learning process, the inculcation of character education based on local wisdom is applied by the teacher through learning materials, learning media, and also the evaluation of learning used. Planting character education is not enough to only be instilled in schools but there must be cooperation with parents of students at home.

Competências infocomunicacionais: estrutura conceitual e indicadores de avaliação
Authors: Borges Jussara
Published: February 2020

O objetivo deste artigo é contribuir com o desenvolvimento teórico e aplicado da área de Alfabetização Informacional, considerando mudanças proeminentes no ambiente informacional, como a cultura de participação e a construção colaborativa de conhecimento. Trata-se de um ambiente que demanda competências em informação, mas também habilidades para interagir e relacionar-se: competências em comunicação. O artigo situa as competências infocomunicacionais teoricamente, articulando as três principais bases que sustentam este estudo: a Alfabetização Informacional (Alfin), a New Media Literacy (NML) e a Metaliteracy. A partir da sistematização desses conceitos, propõe-se uma estrutura em termos de categorias de onde emergem indicadores úteis à avaliação das competências. Os indicadores foram convertidos em questões, apresentadas a estudantes de pós-graduação de quatro países, de cujas respostas extraíram-se evidências de suas competências em termos de informação e comunicação. Os indicadores, baseados na estrutura conceitual, mostraram-se adequados para se conhecer o comportamento infocomunicacional contemporâneo, a partir do qual se manifestaram competências mais ou menos desenvolvidas. Os resultados salientaram uma forte tendência para a aprendizagem e o trabalho em colaboração, embora nem todas competências inerentes encontrem o mesmo nível de desenvolvimento, com destaque negativo para o relacionamento intercultural.
OPAC 2.0: análise das propriedades, serviços e recursos da Web 2.0
Authors: Dias Rafael Gonçalves , Dias Célia da Consolação
Published: February 2020

Nos últimos anos, Catálogos Online de Acesso Público (OPAC) vêm passando por transformações devido ao desenvolvimento tecnológico e por uma susposta exigência de usuários acostumados com serviços mais interativos proporcionados pela Web 2.0. Na tentativa de atender aos anseios dos usuários observa-se em alguns estudos a proposição do desenvolvimento do OPAC 2.0. Neste caso, obverva-se que se o OPAC 2.0 é aquele que está alinhando ao conceito Web 2.0 e faz uso seus mecanismos, considera-se oportuno investigar através de um estudo exploratório as proriedades da Web 2.0, como os princípios, serviços e recursos que dão origem ao proposto OPAC 2.0. Este estudo visa, portanto, proporcionar maior clareza quanto as propriedades da Web 2.0 em relação ao que se espera de um OPAC 2.0. Para esta tarefa recorreu-se a literatura especializada para estabelecer pontos de ligação entre Web 2.0 e Ciência da Informação (CI) e identificar métodos de avaliar, classificar ou identificar elementos da Web 2.0 em serviços de informação. O resultado da pesquisa indica que a literatura especializada ainda carece de fundamentação teórica e procedimentos técnicos para avaliar OPAC que venham a reivindicar o “selo” 2.0. Concluí-se que sem as devidas reflexões e esclarecimento, corre-se o risco de desenvolver serviços desalinhados às reais necessidades dos usuários.
Alguns conceitos da sociologia de Pierre Bourdieu relacionados com a análise de rede social
Authors: Alves Bruno Henrique , Oliveira Ely Francina Tannuri
Published: February 2020

O Campo da Ciência da Informação - CI é um espaço hierarquizado, relativamente autônomo e formado por relações objetivas que se dão em um contexto social. Esta pesquisa objetiva compreender os mecanismos implícitos à geração e construção do conhecimento dos pesquisadores bolsistas de produtividade em pesquisa do CNPq - Conselho Nacional de Desenvolvimento Científico e Tecnológico - em CI e a posição social que ocupam no Campo em questão. De forma mais específica, pretende:  compreender os mecanismos sociais construídos para organizar e facilitar aestruturação das redes de colaboração científica dos pesquisadores bolsistas de produtividade em pesquisa do CNPq em CI;e fundamentar a Análise de Redes Sociais – ARS, a partir da teoria do Campo e os conceitos de Capital Social e Capital Científico, propostos pela Sociologia de Pierre Bourdieu. Para a construção das redes de colaboração científica entre os pesquisadores, utilizou-se o Software Ucinet. A teoria do Campo Científico foi utilizada também para complementar o procedimento de Análise de Redes Sociais, com foco na caracterização e evolução das redes de colaboração científica (2005-2009 e 2010-2014). Como conclusões, destaca-se que, de acordo com os fundamentos da Sociologia de Pierre Bourdieu, para ocupar uma posição de dominante, o pesquisador bolsista de produtividade em pesquisa doCNPqdeve entender a lógica do jogo, pois o Campo possui eixos estruturantes a partir dois quais se identificam os principais jogadores que ocupam esse espaço social de concorrência científica.
Restrições ao acesso informacional: a neutralidade de rede e a prática do zero-rating na governança da Internet
Authors: Garcia e Silva Hermann Bergmann , Marques Rodrigo Moreno
Published: February 2020

Com a expansão das ofertas de gratuidade no tráfego de Internet para acesso a determinadas aplicações ou conteúdos, prática denominada de zero-rating, surgem novos desafios para a governança da Internet, notadamente no que se refere à garantia do tratamento isonômico e não discriminatório do fluxo de informações na web. Nesse contexto, o presente trabalho analisa a experiência internacional de normatização do princípio da neutralidade de rede e da prática do zero-rating, a partir dos marcos regulatórios do Canadá, Chile, Holanda, Índia e União Europeia. Para tanto, foi desenvolvida uma pesquisa descritiva de natureza qualitativa, fundamentada em análises bibliográfica e documental. Os resultados apontam, por um lado, para uma tendência de se regulamentar a proibição de práticas na Internet que tenham como objetivo bloquear, priorizar, degradar ou restringir intencionalmente alguns tipos de conteúdo. Por outro lado, verifica-se a ausência de uniformidade no que se refere ao disciplinamento da prática do zero-rating. Nesses termos, a investigação realizada busca contribuir com a discussão acadêmica acerca da regulação de práticas que limitam o acesso informacional dos usuários da Internet.
Acesso Aberto em questão: novas agendas e desafios
Authors: Luiz Appel André , Albagli Sarita
Published: February 2020

Passados quase 20 anos desde a Declaração de Budapeste (2002) e frente a recorrentes controvérsias em torno dos periódicos científicos, cabe indagar em que medida a crise dos periódicos ganha novos contornos e assume novas dimensões, e como vem repercutindo nos modos de se fazer ciência. O objetivo deste trabalho é problematizar os aspectos que configuram a crise dos periódicos científicos e seus desdobramentos recentes, sistematizando os argumentos sobre as principais questões e desafios atuais nessa questão, bem como caracterizando a emergência de um novo ecossistema de comunicação científica em torno do desenvolvimento de novas plataformas e infraestruturas de publicação. A abordagem metodológica do estudo envolveu: (a) revisão da literatura a partir de uma perspectiva crítica; (b) realização de entrevistas com especialistas e advocates; e (c) levantamento e discussão sobre iniciativas emergentes e inovadoras nesse campo. Como resultados, apontamos o potencial de ampliação da variedade de objetos científicos em circulação, ampliando suas condições de interoperabilidade, de conformação de infraestruturas abertas e governanças comunitárias, até processos mais críticos como a conversão do acesso aberto em modelo de negócio e a verticalização e algoritmização da oferta de serviços à pesquisa científica.

In this investigation we make a systematic study of the univalence of certain
families of integral operators, which are defined by means of the normalized
forms of Jackson?s second and third q-Bessel functions.
On linear operators for which TTD is normal
Authors: Yousefi Ramesh , Dana Mansour
Published: February 2020

A Drazin invertible operator T ? B(H) is called skew D-quasi-normal operator
if T* and TTD commute or equivalently TTD is normal. In this paper, firstly
we give a list of conditions on an operator T; each of which is equivalent
to T being skew D-quasi-normal. Furthermore, we obtain the matrix
representation of these operators. We also develop some basic properties of
such operators. Secondly we extend the Kaplansky theorem and the
Fuglede-Putnam commutativity theorem for normal operators to skew
D-quasi-normal matrices.

Toughness condition for a graph to be all fractional (g,f,n)-critical deleted
Authors: Gao Wei , Wang Weifan , Dimitrov Darko
Published: February 2020

In data transmission networks, the feasibility of data transmission can be
characterized by the existence of fractional factors. If some channels and
stations are not available in the transmission network at the moment, the
possibility of transmission between data is characterized by whether the
corresponding graph structure of the network is critical deleted. Toughness
used to measure the vulnerability and robustness of a network, which is an
important parameter to be considered in network designing. In this paper, we
mainly study the relationship between toughness and the all fractional
critical deleted graph, and a toughness condition for a graph to be all
fractional (g,f,n)-critical deleted is determined.

Existence and global attractivity of periodic solutions to some subclasses of
the following class of difference equations xn+1 = qnxn + f(n,xn, xn-1,..., xn-k), n ? N0, where k ? N0, (qn)n?N0 is a T-periodic sequence (T ?
N), and f : N0 x Rk+1 ? R is a T-periodic function in the first variable,
which for each n ? {0,1,..., T-1} is continuous in other variables,
are studied.
On some types of lightlike submanifolds of golden semi-Riemannian manifolds
Authors: Erdoğan Feyza
Published: February 2020

The main purpose of the present paper is to study the geometry of screen
transversal lightlike submanifolds and radical screen transversal lightlike
submanifolds and screen transversal anti-invariant lightlike submanifolds of
Golden semi-Riemannian manifolds. We investigate the geometry of
distributions and obtain necessary and sufficient conditions for the induced
connection on these manifolds to be metric connection. We also obtain
characterizations of screen transversal anti-invariant lightlike
submanifolds of Golden semi-Riemannian manifolds. Finally, we give two
examples.
Oscillatory and asymptotic behavior of solutions for second-order mixed nonlinear integro-dynamic equations with maxima on time scales
Authors: Agwa Hassan , Naby Mokhtar , Arafa Heba
Published: February 2020

This paper is concerned with the oscillatory and asymptotic behavior for
solutions of the following second-order mixed nonlinear integro-dynamic
equations with maxima on time scales (r(t)(z?(t))?)? + ?t0 a(t,s) f(s,
x(s))?s + ?n,i=1 qi(t) max s?[?i(t),?i(t)] x?(s) = 0, where z(t) = x(t) +
p1(t)x(?1(t)) + p2(t)x(?2(t)), t ? [0,+?)T. The oscillatory behavior of this
equation hasn?t been discussed before, also our results improve and extend
some results established by Grace et al. [2] and [8].
Ideal versions of the Bolzano-Weierstrass property
Authors: Yu Jiakui , Zhang Shuguo
Published: February 2020

Let I, J be ideals on ?, we say that a space X has (I,J)-BW property if every
sequence in X contains a J-converging subsequence indexed by an I-positive
set. This is a common generalization ofBWlike properties types. By modifying
some classic notions, we obtain some characterizations of (I,J)-BW property.
On the dual of Hilbert coefficients and width of the associated graded modules over Artinian modules
Authors: Cheraghi Fatemeh , Mafi Amir
Published: February 2020

Let (A,m) be a commutative quasi-local ring with non-zero identity and let M
be an Artinian co-Cohen-Macaulay R-module with NdimM = d. Let I ? m be an
ideal of R with ?(0:M I) < ?. In this paper, for 0 ? i ? d, we study the
dual of Hilbert coefficients ?i(I,M) of I relative to M. Also, we prove the
dual of Huckaba-Marley?s inequality. Moreover, we obtain some consequences
of this result.
Investigation and corrigendum to some results related to g-soft equality and gf -soft equality relations
Authors: Al-Shami Tareq
Published: February 2020

Since Molodtsov defined the concept of soft sets, many types of soft
equality relations between two soft sets were discussed. Amongthese types
are 1-soft equality and gf-soft equality relations introduced in [1] and
[2], respectively. In this paper, we first aim to show that some results
obtained in [1,2] need not be true, by giving two counterexamples. Second,
we investigate under what conditions these results are correct. Finally, we
define and study the concepts of gf-soft union and gf-soft intersection
for arbitrary family of soft sets.
