Published: September 2020

INTRODUCCIÓN. Las matronas están en una posición privilegiada para identificar y abordar la violencia de género, pero para ello necesitan la formación adecuada. OBJETIVO. El objetivo de este trabajo es conocer la formación realizada por las matronas sobre violencia de género, la percepción de su capacitación para detectar y abordar la violencia de género y sus necesidades formativas. METODOLOGÍA. Estudio cualitativo con un enfoque fenomenológico interpretativo. Se hicieron entrevistas en profundidad a doce matronas que trabajan en atención primaria. RESULTADOS. Las matronas tienen formación y conocimientos sobre violencia de género, obtenidos mayoritariamente gracias a la formación continuada y su experiencia profesional. Sin embargo, esta formación no es suficiente para sentirse capacitadas para la detección y abordaje de la violencia de género. CONCLUSIONES. Las matronas tienen interés por mejorar su formación y capacitación en cuanto a la detección y abordaje de la VG. Sería deseable disponer de un programa de formación continuada en violencia de género para las matronas con un carácter flexible y polivalente para adaptarse mejor a sus intereses formativos.
Flexible A-scan rate MHz-OCT: efficient computational downscaling by coherent averaging
Authors: Pfeiffer Tom , Göb Madita , Draxinger Wolfgang , Karpf Sebastian , Kolb Jan Philip , Huber Robert
Published: September 2020

In order to realize adjustable A-scan rates of fast optical coherence tomography (OCT) systems, we investigate averaging of OCT image data acquired with a MHz-OCT system based on a Fourier Domain Mode Locked (FDML) laser. Increased system sensitivity and image quality can be achieved with the same system at the cost of lower imaging speed. Effectively, the A-scan rate can be reduced in software by a freely selectable factor. We demonstrate a detailed technical layout of the strategies necessary to achieve efficient coherent averaging. Since there are many new challenges specific to coherent averaging in swept source MHz-OCT, we analyze them point by point and describe the appropriate solutions. We prove that coherent averaging is possible at MHz OCT-speed without special interferometer designs or digital phase stabilization. We find, that in our system up to ∼100x coherent averaging is possible while achieving a sensitivity increase close to the ideal values. This corresponds to a speed reduction from 3.3 MHz to 33 kHz and a sensitivity gain of 20 dB. We show an imaging comparison between coherent and magnitude averaging of a human finger knuckle joint in vivo with 121 dB sensitivity for the coherent case. Further, the benefits of computational downscaling in low sensitivity MHz-OCT systems are analyzed.
Multi-resonant refractory prismoid for full-spectrum solar energy perfect absorbers
Authors: Liu Zhengqi , Zhong Haozong , Liu Guiqiang , Liu Xiaoshan , Wang Yan , Wang Junqiao
Published: September 2020

In this work, a feasible way for perfect absorption in the whole solar radiance range is numerically demonstrated via the multiple resonances in a 600-nm-thick refractory prismoid. Under the standard AM 1.5 illumination, the measured solar energy absorption efficiency reaches 99.66% in the wavelength range from 280 nm to 4000 nm, which indicates only a rather small part of solar light (0.34%) escaped. The record harvesting efficiency directly results from the near-unity absorption for the multi-layer refractory resonators, which can simultaneously benefit from the multi-resonant behaviors of the structure and the broadband resonant modes by the material intrinsic features. The absorption including the intensity and frequency range can be adjusted via the structural features. These findings can hold wide applications in solar energy related optoelectronics such as the thermal-photovoltaics, photo-thermal technology, semiconductor assisted photo-detection, ideal thermal emitters, etc.

Authors: Yang Yunhe , Zhou Dong , Liu Xiujuan , Liu Yongjun , Liu Shuangqiang , Miao Peixian , Shi Yanchao , Sun Weimin
Published: September 2020

This paper proposes a novel cholesteric liquid crystal (CLC) film–based dual-probe fiber sensor to monitor volatile organic compound (VOC) gas. The sensor consists of a 2×2 multimode fiber coupler, in which the two output fiber ends are covered by two types of CLC films (CLCF) with different pitches. It can be observed that the reflection peak wavelengths of CLCs shift to the red side as the VOC gas concentration increases. The sensitivities of the two CLCFs are 8.435 nm·L/mmol and 14.867 nm·L/mmol to acetone, 14.586 nm·L/mmol and 29.303 nm·L/mmol to ethanol, respectively. In addition, the dependence of the peak wavelength shift of CLCF on the total concentration of the acetone and ethanol mixed gas at different mixing ratios is measured. The linear relationships between the peak shift of CLCFs, the total mixed gas concentration and acetone/ethanol ratio are calculated using the least-squares method. Therefore, this proposed dual-probe fiber optic sensor can distinguish the concentrations of acetone and ethanol in a mixed gas of acetone and ethanol.

nonlinear crystals and a highly stable 2 µm picosecond pump laser based on Ho:YLiF4. An excellent energy extraction is achieved by reusing the pump pulse after the third parametric power amplification stage, resulting in 3.4 mJ idler pulses at a center wavelength of 4.9 µm. Pulses as short as 89.4 fs are achieved, close to only five optical cycles. Taking into account the pulse energy, a record high peak power of 33 GW for high-energy mid-IR OPCPAs beyond 4 µm wavelength is demonstrated.
Mode multiplexer for guided optical and acoustic waves
Authors: Dostart Nathan , Popović Miloš A.
Published: September 2020

Integrated acousto-optic (AO) devices utilize the strong overlap of acoustic and optical fields in a waveguide to facilitate efficient photon–phonon (Brillouin) interactions. For example, acoustic waves offer a lossless modulation mechanism for light. “Brillouin active” photonic platforms are currently being developed that may see optical, acoustic, and AO waveguide circuits on the same chip, where guided light and sound come together in active interaction regions. A key missing component for such a platform is a device that can multiplex modes across these two physical domains. We propose and describe a new class of optical and acoustic components, the “acoustic–optical mode multiplexer” (AOMM), a device that takes respective optical and acoustic waveguides as input ports and couples their excited guided modes into a single, joint output waveguide. We show an example suspended silicon–silicon dioxide design that combines two optical modes and a spatially separate acoustic mode into a single, co-guided output port with low insertion loss down to 0.3 dB for both optical and acoustic modes, and reflection below

Typical methods to decode a complex orbital-angular-momentum (OAM) spectrum suffer from issues such as a narrow OAM range, unstable interferometer, and long measuring time. In this Letter, we use a single-beam interferometer to measure the complex OAM spectrum with a single-pixel detector. The complex OAM spectrum ranging from

to 10 can be measured in 11 ms with the fidelity approach of 97.0%, experimentally. Our approach allows one to characterize an unknown coherent field with any complex basis, e.g., the Laguerre–Gaussian (LG) basis is used for radial index spectrum measurement. Furthermore, single-pixel complex amplitude imaging based on the LG spectrum acquisition is presented, and the advantages in resolution and flexibility are demonstrated.

O que tinha de ser: vivências coloniais em A. Lobo Antunes e V. S. Naipaul
Authors: Santana Maria Helena
Published: September 2020

A queda dos últimos impérios coloniais no século XX, nomeadamente as colónias portuguesas em África, é frequentemente descrita como um processo normal de mudança – a razão histórica ‘como tinha de ser’. As narrativas ficcionais, por seu lado, mostram-nos o lado de dentro da História, visto através do olhar de personagens individualizadas. Os romances de V.S. Naipaul e A. Lobo Antunes oferecem-nos testemunhos impressivos de luso-africanos tentando dar sentido às suas experiências falhadas ou debatendo-se com memórias traumáticas. Este texto analisa a forma como os dois autores produzem imagens subjetivas do processo de (des)colonização, partilhando alguns pontos de vista sobre um mundo em mudança.
O poder das molduras: a temporalidade da fotografia e a retratística na obra de Eça de Queirós
Authors: Bishop-Sanchez Kathryn
Published: September 2020

O presente artigo analisa a inclusão de pinturas e de fotografias em três romances de Eça de Queirós, designadamente O primo Basílio, Os Maias e A tragédia da Rua das Flores, como instantâneos narrativos que imortalizam momentos-chave em textos literários. A partir do “enquadramento” cinemático de 24 Frames, o último filme de Abbas Kiarostami, a minha análise foca o modo como a imagem de retratos pintados ou fotografias assumem significado para além daquilo que retratam, e também o modo como as respetivas narrativas permitem uma reconstituição daquilo que antecedeu a criação da imagem enquadrada e daquilo que se lhe segue.
Pós-verdade e Distopia
Authors: Villanueva Darío
Published: September 2020

Na nossa sociedade pós-moderna, um novo conceito surgiu com força: o de pós-verdade. Segundo o Dicionário Oxford, post-truth é um adjetivo que qualifica circunstâncias que denotam que os factos objetivos têm muito menos influência na formação da opinião pública do que os apelos à emoção e às crenças pessoais. Não parece plausível que Donald Trump tenha sido leitor de filósofos como Jacques Derrida ou Michel Foucault. É, contudo, evidente a ligação entre a pós-verdade e um clima de pensamento pós-moderno por eles propiciado. À parte os embustes de Trump e dos Brexiters, não deixa de denunciar-se a intensificação de campanhas desinfomativas noutros países como a Rússia, Hungria ou Turquia. E em Espanha, olhe-se para o chamado processo em Catalunha. O género romanesco das distopias conta já com um corpus considerável. Este assunto da pós-verdade encontra a sua primeira fundamentação distópica no romance 1984 de George Orwell, publicado em 1949, embora a primeira obra da série tenha sido Nós de Evgueni Zamiatin, de 1924. Entre ambas as distopias, Aldous Huxley tinha publicado Admirável Mundo Novo, de 1932, cujo título, tomado de Shakespeare, sugere uma tirania aparentemente amável. Porém, nela funciona já a pós-verdade.

Authors: Gómez Martínez Maria Rosa
Published: September 2020

La Asamblea Local de Cruz Roja Española de Elche inició su andadura con carácter formal en el mes de septiembre de 1909; el talante altruista de la “brigada de camilleros” y su vida económica, compuesta principalmente por cuotas de socios, subvenciones del ayuntamiento y celebraciones para recaudar fondos, así como los servicios prestados para toda la población, advierten de la existencia de cobertura sanitaria en un momento de valor singular, como es la dictadura de Miguel Primo de Rivera. Los principios que rigen la Asamblea son los mismos que propone el Comité Internacional de la Cruz Roja en 1921: caridad, universalidad, independencia e imparcialidad. Objetivo: identificar qué se conoce sobre los inicios de la Cruz Roja Española en la ciudad de Elche y la relación existente con sus principios: caridad, universalidad, independencia e imparcialidad. Método: se llevó a cabo una investigación histórica basada en la revisión bibliográfica. Fuentes documentales: catálogos documentales de bibliotecas y archivos documentales, bases de datos electrónicas, catálogos de revistas especializadas en historia y otras fuentes de red. Descriptores utilizados: Cruz Roja, Cruz Roja Española, Cruz Roja Local. Resultados: en el análisis se incluyeron documentos procedentes de estudios basados en fuentes primarias y los resultados se presentan en 4 apartados: Composición y vida económica, Celebraciones para recaudar fondos: la Fiesta de la Banderita, Acuerdos municipales y Servicios prestados. Conclusión: existe una clara relación de la labor desarrollada por la Asamblea de la Cruz Roja Española de Elche y los principios en los que se orienta, desarrollando cada uno de ellos en su vida cotidiana; así se deprende de los documentos analizados de la época tanto de comunicaciones y actas del ayuntamiento como de prensa histórica.

Diarrhea is one of many health issues in developing country like Indonesia, because the sickness and the death number are still high. According to health profile of Semarang City, the people who suffer from diarrhea from 2010-2015 are decreasing. The lowest point happened at the year 2013 with the total case of 38.001, however there are an increasing number from 2014-2015. The distribution data of diarrhea is a spatial data. The differences between environment and sanitation could cause spatial heterogeneity. The spatial heterogeneity could cause the produced variant value no longer constant, but instead it is different on each region. Therefore, regression model that involves the effects of spatial heterogeneity is needed, which are Geographically Weighted Regression (GWR) that is built by Weighted Least Square (WLS) adjuster. Although, GWR parameter adjuster that used WLS is very sensitive with the existence of outliers. The existence of the outlier in the data will create a huge residual. Thus, more robust method is needed, which is Least Absolute Deviation (LAD) methods in order to estimate the parameter on model GWR. This model is called Robust GWR (RGWR). The result shows that the model events of diarrhea on each region in Semarang City are different. Furthermore, the model events of diarrhea with RGWR model generate MAPE 16,3396% which means the performance of RGWR is formed well. Keyword: Diarrhea, Robust, Geographically Weighted Regression, Least Absolute Deviation

Time series analysis is an analysis used to predict a time-observed data, one of which is the ARIMA model. ARIMA model assumes a constant residual variance (homogeneous). While financial data usually produce ARIMA model with variance error that is not constant. If the assumption of homogeneity of the residual variance is not met, then the method that can be used is ARCH or GARCH model. Another method that can be used on the data assuming the homogeneity of the variance error is not met is the Neural Network model. In this model we use Neural Network model with variance and residual as the input variables that obtained from ARCH / GARCH model. The data used are BSDE and HMSP asset portfolio returns from November 14, 2016 to January 18, 2018. In this study the selected input variables are from ARIMA (1.0.1) GARCH (1,1) model. The best Neural Network model obtained is Neural Network model with 10 hidden layers with MSE value 6.58 x10-10 with model train evaluation which is MAPE value 1.14441%.Keywords: Time series Analysis, ARCH / GARCH, Neural Network, Return.

Increased economic improvement is one way to improve people's welfare in certain areas. Gross Regional Domestic Product (GRDP) is one of the macroeconomic indicators used to measure economic growth in a region. Related to the economy in Central Java Province increased from year to year. Increasing economic growth is inseparable from the contribution of factors that sufficiently contribute to the GRDP. Factors that are the cause of GRDP are Regional Original Income, Foreign Investment, and Domestic Investment. The method used to model the factors that influence Gross Regional Domestic Product is the Multivariate Adaptive Regression Spline (MARS) method and combine it with Bagging. MARS method is one method that uses nonparametric regression and high dimension data. The best model used is a model with a combination of BF = 6, MI = 1, MO = 0 with GCV of 5.667,6680. Then bagging is done on the initial data set with 10, 25, 35, 40, 55, 75, 85, 90 and 100 bootstrap replications. GCV produced in bagging MARS 2.258,6192. GCV valuesobtained from MARS bagging are smaller compared to the MARS method. This shows that bagging can reduce the value of GCV and increase accuracy, making this method can be used in this study. Keywords: GRDP, GCV, MARS, Bagging

The k-medoids method is a non-hierarchical clustering to classify n object into k clusters that have the same characteristics. This clustering algorithm uses the medoid as its cluster center. Medoid is the most centrally located object in a cluster, so it’s robust to outliers. In cluster analysis the objects are grouped by the similarity. To measure the similarity, it can be used distance measures, euclidean distance and cityblock distance. The distance that is used in cluster analysis can affect the clustering results. Then, to determine the quality of the clustering results can be used the internal criteria with silhouette width and C-index.

Import is activities to enter goods into the territory of a country, both commercial and non-commercial include goods that will be processed domestically. Import is an important requirement for industry in Central Java. The increase in high import values can cause deficit in the trade balance. Appropriate information about the projected amount of imports is needed so that the government can anticipate a high increase in imports through several policies that can be done. The forecasting method that can be used is ARIMA Box-Jenkins. The development of modeling in the field of time series forecasting shows that forecasting accuracy increases if it results from the merging of several models called ensemble ARIMA. The ensemble method used is averaging and stacking. The data used are monthly import value data in Central Java from January 2010 to December 2018. Modeling time series with Box-Jenkins ARIMA produces two significant models, namely ARIMA (2,1,0) and ARIMA (0,1,1). Both models are combined using the ARIMA ensemble averaging and stacking method. The best model chosen from the ARIMA method and ensemble ARIMA based on the least RMSE value is the ARIMA model (2,1,0) with RMSE value of 185,8892 Keywords: Import, ARIMA, ARIMA Ensemble, Stacking, Averaging

Multi Attribute Decision Making (MADM) is one of the decision-making methods to determine the best alternative from a number of alternatives based on certain criteria. There are several methods that can be used to solve MADM problems including Simple Additive Weighting (SAW) and Weighted Aggregated Sum Product Assesmen (WASPAS). Both methods are applied in the selection of prospective new students. In this study, MTsN Kisaran selected 192 students received from 422 registrans and determined certain criteria to get quality students. The criteria determined are the value of the national exam, the value of the Al-Qur'an test, and the value of the academic potential test. The method applied is SAW and WASPAS with the  weighting Rank Order Centroid (ROC). Then a sensitivity analysis is carried out to determine a viable methods selected to obtain optimal results. This research was designed with the help of the Matlab GUI as a computing tool to simplify and accelerate the selection process. Based on the results of the study, the average percentage value of sensitivity for the SAW method was -0.82% while the WASPAS method was -0.87%. With the existence of sensitivity analysis it can be known the most appropriate method for this case is the SAW method.                                                   Keywords: Students, SAW, WASPAS, ROC, Sensitivity, GUI Matlab.

Adaptive Neuro Fuzzy Inference System (ANFIS) is a method that uses artificial neural networks to implement fuzzy inference systems. The optimum ANFIS model is influenced by the selection of inputs, number of membership and rules. In general, the selection of ANFIS input is based on Autoregressive (AR) unit as a result of ARIMA preprocessing. Thus it requires several assumptions. In this research, an alternative selection of ANFIS input based on Lagrange Multiplier Test (LM Test) is used to test hypothesis for the addition of one input. Preprocessing is conducted to obtain the value of partial autocorrelation against Zt. The input lag variable which has the highest partial autocorrelation is the first input ANFIS. The next input selection is selected based on LM test for adding one variable. To test the performance of LM Test, an empirical study of two groups of generated data and low quality rice prices is conducted as a case study. Generating data with stationary and non-stationary criteria has a good performance because it has very good forecasting ability with MAPE out sample for each characteristic are 5.6785% and 9.4547%. In the case study using LM Test, the selected input are and  with the number of membership 2. The chosen model has very good forecasting ability with MAPE outsampel 6.4018%. Keywords : ANFIS, ANFIS Input, LM-Test, Low Quality Rice Prices, Forecasting

In quality assurance of hexagonal paving block products, quality control is needed so the products that produced are in accordance with the specified standards. Quality control carried out involves two interconnected quality characteristics, that is thickness and weight of hexagonal paving blocks, so multivariate control chart is used. Improved Generalized Variance control chart is a tool used to control process variability in multivariate manner. Variability needs to be controlled because of in a production process, sometimes there are variabilities that caused by engine problems, operator errors, and deffect in raw materials that affect the process. The purpose of this study is to apply Improved Generalized Variance control chart in controlling the quality of hexagonal paving block products and calculating the capability of production process to meet the standards. Based on the assumption of multivariate normal distribution test, it can be seen that the data of quality characteristics of hexagonal paving blocks have multivariate distribution. While based on the correlation test between variables it can be concluded that the characteristics of the quality of thickness and weight correlate with each other. The result of the control using these control chart shows that the process is statistically in control. The results of process capability analysis show that the production process has been running according to the standard because the process capability index value is generated using a weighting of 0.5 for each quality characteristic that is 1.01517. Keywords: Paving Block, Quality Control, Variability, Improved Generalized Variance, Process Capability Analysis

Published: September 2020

Ehlers-Danlos syndrome (EDS) comprises a group of heritable connective tissue disorders which has as cardinal features varying degrees of skin hyperextensibility, joint hypermobility, easy bruising and skin fragility. The 2017 New York nosology distinguishes 13 types of EDS, which all, except hypermobile EDS, have a known molecular basis. Hypermobile EDS is recognized as a common and often disabling disorder, incorporating benign joint hypermobility syndrome. EDS needs to be differentiated from other connective tissue disorders, in particular Marfan syndrome, Loeys-Dietz syndrome and cutis laxa. The frequent types of EDS can be diagnosed after careful history taking and clinical examination, but for definite diagnosis molecular confirmation is needed in all types. Management for EDS patients preferably is provided by multidisciplinary teams in expertise centres. After diagnosing EDS genetic counselling is an essential part of the management of patients and their family.

Background: Increased oxidative stress causes inflammation and increases angiogenesis. It presumed to promote the proliferation of endometriosis tissue. Kebar grass (Biophytum petersianum) and other herbs such as green tea and Cucumis melo, which contain high antioxidants, are expected to decrease oxidative stress, inflammation, angiogenesis, and reduced endometriosis implants.Objective: To investigate the effects of Kebar grass, green tea, and Cucumis melo to malondialdehyde serum, tumor necrosis factor alpha, and vascular endothelial growth factor expression, and the area of the endometriotic implants.Methods: Twenty-eight mice were divided into four groups, i.e., the first group of endometriosis mice was given Kebar grass extract; the second group was assigned green tea extract, the third group was given the combination of Cucumis melo extract–gliadin, and the last containing the untreated endometriosis mice as the control. Each treatment was given for 14 days. The data of MDA serum level, the area of the endometriotic implants, TNF-α, and VEGF expression were collected and analyzed.Results: The MDA serum levels of the groups treated with Kebar grass extract, green tea extract, and Cucumis melo extract – gliadin were significantly lower (p=0.001) than the control group. TNF-α expression of the groups provided with each treatment also lower than the control groups (p=0.002). However, only the administration of the Cucumis melo extract–gliadin resulted in lower VEGF expression compare with the control (p=0.017). Finally, the area of the endometriotic implants of the mice models administered with each treatment was smaller than the control group (p=0.003).Conclusion: Kebar grass as well as green tea and Cucumis melo–gliadin inhibits endometriotic implants extension by decreasing MDA serum and TNF-α expression.
