<b> Acesso do transfronteiriço aos serviços de saúde em cidades gêmeas do Paraná/ Cross-border access to health services in twin cities of Paraná
Authors: Aikes Solange , Frizon Rizzoto Maria Lucia 
Published: December 2019

Objetivo: compreender a dinâmica de acesso do transfronteiriço aos serviços de saúde. Método: pesquisa exploratória, descritiva e de campo em quatro cidades gêmeas do Paraná (Foz do Iguaçu, Guaíra, Santo Antônio do Sudoeste e Barracão). Os dados foram obtidos por meio de entrevista semiestruturada aplicada aos gestores de saúde e submetidos à análise temática de conteúdo proposta por Bardin. Resultados: quatro categorias temáticas discutidas criticamente com a literatura, observou-se no estudo que a) há um maior acolhimento nos municípios menores, sobretudo na atenção básica; b) o financiamento como principal entrave para o acesso do transfronteiriço; c) a decisão discricionária do profissional de saúde no momento do atendimento face à ausência de diretrizes institucionalizadas que perdurem. Considerações finais: verificou-se que o acesso ao serviço de saúde do transfronteiriço é instável e confuso, mas a disseminação do pensamento integrador e de solidariedade entre os povos, a partir do nível local, poderá contribuir para ampliar a noção de cidadania e de acolhimento ao transfronteiriço.
Comparison of Effectiveness of Oral Tranexamic Acid with that of the Topical Modified Kligman's Formula in the Treatment of Melasma
Authors: Bansal Aditi , Sardesai Vidyadhar R. 
Published: December 2019

Context:
Melasma is an acquired disorder of hyperpigmentation presenting over the face. Modified Kligman's formula is used most commonly as treatment modality. Considering the various side effects of individual components of topical modified Kligman's formula, the use of oral tranexamic acid might be a better and safer alternative for the treatment of melasma.

Aims:
This study aims to compare the efficacy of oral tranexamic acid with that of topical modified Kligman's formula in the treatment of melasma. To assess the degree of improvement in pigmentation objectively using Melasma Area and Severity Index at baseline and after 4 weeks of treatment with oral tranexamic acid and topical modified Kligman's formula and to compare the side effects, if any, associated with both the modalities.

Settings and Design:
This was randomized, comparative, prospective, open-labeled study.

Methods:
This study was done in a tertiary care hospital from September 2018 to June 2019. Overall, 40 patients with clinical diagnosis of melasma were included in the study.

Statistical Analysis Used:
Paired t-test and unpaired t-test.

Results:
Improvement was noted in patients belonging to both the groups. After applying paired t-test, it was found that results were statistically significant in both the treatment groups. When both the groups were compared statistically using unpaired t-test, both the groups showed statistically equivalent results.

Conclusions:
Both oral tranexamic acid and modified Kligman's formula were equally effective in the treatment of melasma. Oral tranexamic acid is a better and safer alternative than the modified Kligman's formula to initiate the treatment in melasma.

Authors: Sebastian Juny , Ramesh Madhan , Mahin Chanchal Anandhy , Jose Linda , Sirasgi Vijayalaxmi Nagappa , Raveendran Adhirai 
Published: December 2019

Introduction:
Cutaneous adverse drug reactions (CADRs) are one of the significant clinical problems not only in dermatology practice but also in any areas where drug is involved.

Aim:
The aim of this study was to determine the incidence, pattern, predictors, and direct cost associated with the management of CADRs.

Methodology:
It was a prospective, observational study which involved both spontaneous reporting and intensive monitoring. Study patients were followed throughout their hospital stay. Where a CADR was detected, all the required data were collected and analyzed. Bivariate regression analysis was used to determine the predictors of CADRs.

Results:
The incidence of CADRs was 25.01%. Drug classes most commonly implicated in CADRs were antibiotics (29.055%), nonsteroidal anti-inflammatory drugs (17.31%), antineoplastic drugs (11.17%), and antitubercular drugs (10.05%). Majority (66.48%) of the reactions were “probable” in their causality category. Serious CADRs accounted for 1.67%. There was a significant association between the occurrence of CADRs and the use of ≥2 medications, adult patients, and male gender. The total and average costs incurred in the management of CADRs were INR 61,116/- and 734/-, respectively.

Conclusion:
Among the study population, adults, male gender, and patients receiving ≥2 medications and patients who presented with ≥2 comorbidities were identified as the predictors for the development of CADRs. Hence, it is important to monitor closely the patients with the identified risk factors for the CADRs to minimize the complications associated with the CADRs.

Abstract. Aromatic hydrocarbons make up a large fraction of anthropogenic volatile organic compounds and contribute significantly to the production of tropospheric ozone and secondary organic aerosol (SOA). Four toluene and four 1,2,4-trimethylbenzene (1,2,4-TMB) photooxidation experiments were performed in an environmental chamber under relevant
polluted conditions (NOx∼10 ppb). An extensive suite of instrumentation including two proton-transfer-reaction mass spectrometers (PTR-MS) and two chemical ionisation mass spectrometers (NH4+ CIMS and I− CIMS) allowed for quantification of reactive carbon in multiple generations of hydroxyl radical (OH)-initiated oxidation. Oxidation of both species produces ring-retaining products such as cresols, benzaldehydes, and bicyclic intermediate compounds, as well as ring-scission products such as epoxides and dicarbonyls. We show that the oxidation of bicyclic intermediate products leads to the formation of compounds with high oxygen content (an O:C ratio of up to 1.1). These compounds, previously identified as highly oxygenated molecules (HOMs), are produced by more than one pathway with differing numbers of reaction steps with OH, including both auto-oxidation and phenolic pathways. We report the elemental composition of these compounds formed under relevant urban high-NO conditions. We show that ring-retaining products for these two precursors are more diverse and abundant than predicted by current mechanisms. We present the speciated elemental composition of SOA for both precursors and confirm that highly oxygenated products make up a significant fraction of SOA. Ring-scission products are also detected in both the gas and particle phases, and their yields and speciation generally agree with the kinetic model prediction.
Infrasound and seismoacoustic signatures of the 28 September 2018 Sulawesi super-shear earthquake

Published: December 2019

Abstract. A magnitude 7.5 earthquake occurred on 28 September 2018 at 10:02:43 UTC
near the city of Palu on the Indonesian island of Sulawesi. It was a
shallow, strike-slip earthquake with a rupture extending to a length of about
150 km and reaching the surface. Moreover, this earthquake was identified as
one of very few events having a super-shear rupture speed. Clear and long-lasting infrasound signatures related to this event were
observed by four infrasound arrays of the International Monitoring System of
the Comprehensive Nuclear-Test-Ban Treaty Organization as well as by one
national infrasound station in Singapore. Although these infrasound stations
SING (Singapore), I39PW (Palau), I07AU (Australia), I40PG (Papua New Guinea)
and I30JP (Japan) are located at large distances of between 1800 and 4500 km
from the earthquake's epicentral region, the observed infrasound signals
associated with this event were intense, including both seismic and acoustic
arrivals. A detailed study of the event-related infrasound observations and the
potential infrasound generation mechanisms is presented, covering
range-dependent infrasound transmission loss and propagation modeling and
characterization of the atmospheric background conditions, as well as
identification of the regions of seismoacoustic activity by applying a back-projection method from the infrasound receivers to potential source regions.
This back projection of infrasonic arrivals allows one to estimate that the main
infrasound source region for the Sulawesi earthquake is related to the
extended rupture zone and the nearby topography. This estimation and a
comparison to other super-shear as well as large regional earthquakes
identify no clear connection between the earthquake's super-shear nature
and the strong infrasound emission.
Study on real-time correction of site amplification factor
Authors: Xie Quancai , Ma Qiang , Zhang Jingfa , Yu Haiying 
Published: December 2019

Abstract. The site amplification factor was usually considered to be
scalar values, such as amplification of peak ground acceleration or peak
ground velocity, or increments of seismic intensity in the earthquake early
warning (EEW) system or seismic-intensity repaid report system. This paper focuses
on evaluating an infinite impulse recursive filter method that could produce
frequency-dependent site amplification and compare the performance of the
scalar-value method with the infinite impulse recursive filter method. A
large number of strong motion data of IBRH10 and IBRH19 of the Kiban Kyoshin
network (KiK-net) triggered in more than 1000 earthquakes from 2004
to 2012 were selected carefully and used to obtain the relative site
amplification ratio; we model the relative site amplification factor with a
casual filter. Then we make a simulation from the borehole to the surface and also
simulate from the front-detection station to the far-field station. Compared to
different simulation cases, it can easily be found that this method could
produce different amplification factors for different earthquakes and could
reflect the frequency-dependent nature of site amplification. Through these
simulations between two stations, we can find that the frequency-dependent
correction for site amplification shows better performance than the amplification factor relative to velocity (ARV)
method and station correction method. It also shows better performance than
the average level and the highest level of the Japan Meteorological Agency (JMA)
earthquake early warning system in ground motion prediction. Some cases in which simulation
did not work very well were also found; possible reasons and
problems were analyzed and addressed. This method pays attention to the
amplitude and ignores the phase characteristics; this problem may be improved
by the seismic-interferometry method. Frequency-dependent correction for
site amplification in the time domain highly improves the accuracy of
predicting ground motion in real time.
Generation of Rossby waves off the Cape Verde Peninsula: the role of the coastline
Authors: Sirven Jérôme , Mignot Juliette , Crépon Michel 
Published: December 2019

Abstract. In December 2002 and January 2003 satellite observations
of chlorophyll showed a strong coastal signal along the west African coast
between 10 and 22∘ N. In addition,
a wavelike pattern with a wavelength of about 750 km
was observed from 20 December 2002 and was detectable
for 1 month in the open sea, south-west of the Cape Verde Peninsula.
Such a pattern suggests the existence of a locally generated
Rossby wave which slowly propagated westward during this period. This hypothesis
was confirmed by analysing sea surface height provided by satellite altimeter during
this period. To decipher the mechanisms at play, a numerical study
based on a reduced-gravity shallow-water model has first been conducted. A wind burst,
broadly extending over the region where the offshore oceanic signal is observed,
is applied for 5 d. A Kelvin wave quickly develops along the northern edge
of the cape, then propagates and leaves the area in a few days.
Simultaneously, a Rossby wave whose characteristics seem similar
to the observed pattern forms and slowly propagates westward.
The existence of the peninsula limits the extent of the wave
to the north. The spatial extent of the wind burst
determines the extent of the response and correspondingly the timescale
of the phenomenon (about 100 d in the present case). When the wind burst
has a large zonal and small meridional extent, the behaviour
of a wave to the north of the peninsula differs
from that to the south.
These results are corroborated and completed by an analytical study of a linear
reduced-gravity model using a non-Cartesian coordinate system. This system is
introduced to evaluate the potential impact of the coastline shape.
The analytical computations confirm that a period of around 100 d
can be associated with the observed wave considering the value of the wavelength;
they also show that the role of the coastline remains moderate at such timescales.
By contrast, when the period becomes shorter (smaller than 20–30 d),
the behaviour of the waves is modified because of the shape of the coast.
South of the peninsula, a narrow band of sea isolated from the rest
of the ocean by two critical lines appears. Its meridional extent is about 100 km
and Rossby waves could propagate there towards the coast.
Friendship without Reciprocation? Aristotle, Nietzsche, and Blanchot
Authors: Romero-iribas Ana , Smith Graham M. 
Published: December 2019

Abstract
Must friendship involve reciprocity? Drawing on resources in the thought of Aristotle, Nietzsche, and Blanchot this article advances two claims. First, there isn't simply one form of reciprocity but various forms. The article names two such forms. “Reciprocity as exchange” casts reciprocation as active and involves exchange of benefits in a recognized cycle. In contrast, “reciprocity as correspondence” tolerates degrees of inactivity and connects friends by mutual admiration or commonality of purpose. Second, the article claims that while reciprocation is a feature of some friendships it is not necessary to all. It is possible to conceive of friendship without reciprocation. In these alternative friendships it is the separateness of the friends rather than their togetherness which is central. The article concludes that this minor strand of reciprocation suggests a form of political friendship based around a common heterogeneity, difference, and otherness.
Dual Mobility Bearing Articulations Result in Lower Rates of Dislocation After Revision Total Hip Arthroplasty
Authors: Li William T. , Kozick Zachary , Sherman Matthew , Restrepo Camilo , Smith Eric B. , Courtney P. Maxwell 
Published: December 2019

Introduction:
The purpose of our study is to directly compare the rates of instability after revision total hip arthroplasty (THA) between a modular dual mobility (DM) and a conventional polyethylene single-bearing surface.

Methods:
We retrospectively reviewed a consecutive series of patients who underwent revision THA from 2012 to 2016 at a single institution with a minimum of 2 years of follow-up. Rates of re-revision, dislocation, complications, and short-form (SF-12) scores were compared between the DM and single-bearing groups. To control for confounding variables, a multivariate logistic regression analysis was performed.

Results:
Of the 267 revision THA patients, 94 patients had a DM bearing articulation (36%), whereas 173 patients (64%) had a conventional single-bearing with a mean follow-up of 37.8 months (range 24 to 73 months). The DM group was more likely to undergo revision THA for instability compared with the single-bearing group (8.5% versus 1.2%, P ≤ 0.005) but had reduced incidence of postoperative dislocations (2.1% versus 8.7%, P = 0.067) and no difference in the rates of re-revisions (9.6% versus 11.6%, P = 0.770). When controlling for confounding variables, patients who received a DM liner had lower rates of dislocation postoperatively than those of single-bearing (odds ratio 0.12, P = 0.019).

Discussion:
Even with a selection bias of surgeons using DM for patients at high risk of instability, patients undergoing revision THA with a DM bearing have reduced rates of dislocation at the intermediate-term follow-up. Further study is needed to identify any potential longer-term complications which may result from a modular DM bearing.
Extended algorithm to construct a quadtree from Freeman chain code in four directions
Authors: Nerat Andrej , Strnad Damjan , Zupančič Eva , Žalik Borut 
Published: December 2019

This paper introduces improvements to the algorithm that was proposed in 2001 by Chen and Chen. The algorithm constructs a quadtree directly from Freeman chain code in four directions. We have improved the algorithm in two ways: Firstly, a time efficient solution using the space filling Z-order curve is proposed for a self-intersection case that was not considered by Chen and Chen. Secondly, the algorithm is expanded to handle geometric objects containing holes. The computational efficiency of the extended algorithm was confirmed by the experiments.

Published: December 2019

The main aim of the research was to develop cognitive instruments that allow justification of decisions in national innovation policy. In the theoretical part of research fundamentals of national innovation policies of EU-members and Ukraine were compared to reveal factors that can accelerate innovation development. In the empirical part of research the analysis of innovation capability of Ukrainian enterprises was conducted based on financial, statistic and management reports and it confirmed that companies systematically conducted innovation activities, reached higher levels of innovation potential, innovative business opportunities and margin of economic security and, consequently, have more innovative capacities for innovation of all types.
The formation of cognitive analytical base allowed the application of scenario modelling at the level of public management of innovation activity. Cognitive modelling approach was justified firstly by increased volatility in economic conditions of modern realities of crisis in the national economy, and secondly high-cost and risky innovations, fast diffusion of information resources during the introduction of innovation processes, and thirdly, the presence of the mutual influence of objects of national innovation system.
Between dream and reality: The rehabilitation of war-disabled Belgian soldiers, 1914 – 1921
Authors: Verstraete Pieter 
Published: December 2019

Este artículo pretende contribuir al creciente interés por la historia de la discapacidad, la historia de la educación de personas con discapacidad y la historiografía existente sobre la Gran Guerra. Se centrará en la rehabilitación de los soldados belgas ciegos y físicamente discapacitados. El artículo toma como punto de partida la ceremonia del Soldado Desconocido, que se celebró a principios de los años veinte. Aunque a todo el mundo le resulta familiar la Columna del Congreso de Bruselas y la llama eterna que arde en la tumba del soldado desconocido, pocos son los que conocen que fue un hombre ciego quien jugó un papel importante en la ceremonia fúnebre y que fueron ocho soldados físicamente discapacitados los que llevaron al soldado desconocido a su lugar de descanso final. En esta ceremonia, se creó implícitamente una imagen exitosa de rehabilitación y reeducación que mostraba que los soldados discapacitados podían volver a jugar un papel significativo en la sociedad. Esta imagen será desmenuzada a través de un estudio en detalle de las diversas fuentes que se preservan en los archivos de Flandes y Bruselas, incluidos los Archivos del Estado, los Archivos del Palacio Real, los del Museo Real de la Fuerzas Armadas e Historia Militar, los del Instituto Nacional Belga para los Veteranos y Víctimas de Guerra y los del St. Dunstan’s Institute en Londres. A partir del material fotográfico y los expedientes personales de los soldados discapacitados belgas, se demostrará que la rehabilitación no fue en absoluto un «paseo por el parque» y que para un número de soldados sencillamente no fue posible. Más específicamente, nuestra presentación se centrará en las maneras en que el concepto de rehabilitación tomó forma en los institutos de rehabilitación belgas como el de Boschwoorde para soldados ciegos y la escuela de Port-Villez (Francia) para soldados discapacitados.
A resolução de problemas como um saber necessáro à formação de professores, uma matemática para ensinar
Authors: Morais Rosilda Dos Santos 
Published: December 2019

El presente texto problematiza «resolución de problemas» y «Resolución de problemas» como cosas de diferentes naturalezas. Con este fin, guiado por la pregunta: ¿Se ha trabajado la resolución de problemas durante muchos años en términos de conocimiento que se debe enseñar «savoir à enseigner» y no como conocimiento para enseñar «savoir pour enseigner?». La resolución de problemas gana la escena y se reclama basado en marcos teóricos y metodológicos, estado epistemológico de saber enseñar, matemáticas para enseñar. Además, se afirma que tal conocimiento para enseñar está en el corazón de la formación docente en matemáticas y su enseñanza. Para respaldar esta afirmación, destacan los documentos oficiales de Brasil, por ejemplo, la nueva Base Nacional Curricular Común (BNCC), todo lo cual subraya la importancia del trabajo de resolución de problemas. Finalmente, cuestionamos el papel desempeñado por George Polya como formador de maestros.
