TERRITORIOS RESILIENTES: MANCOMUNALES Y CONCEJOS EN EL SUR DEL DUERO DURANTE LA EDAD MEDIA
Authors: Martín Viso Iñaki
Published: July 2021

Los estudios sobre el sur del Duero medieval han subrayado la importancia de los espacios comunales bajo control concejil. Se considera que su origen procede de la abundancia de baldíos en un territorio escasamente poblado y del interés ganadero de las elites de las villas. Sin embargo, la revisión de los datos existentes, tanto escritos como palinológicos, revela que se trataba de paisajes que ya estaban en uso antes del siglo XII, cuando se produjo la integración política en los reinos cristianos. La construcción del poder concejil se llevó a cabo mediante la afirmación de su función como garante de estas áreas. Se mantuvo así un modelo de usos que combinaba la propiedad concejil y el aprovechamiento por parte de los habitantes de las aldeas vecinas en el marco de unos territorios supralocales que mostraron una acusada resiliencia. Por tanto, la relevancia de los espacios comunales no provenía de una iniciativa sobre áreas baldías sino de la adecuación a una realidad preexistente, aunque a partir del siglo XII se produjeron cambios provocados por la redefinición y “politización” de tales áreas de uso mancomunal.
ENTRE EL ESTIGMA Y LA COMICIDAD POPULAR: SIGNIFICACIONES DEL VENDEDOR CALLEJERO ENTRE LOS SIGLOS XVI Y XVII
Authors: Campo Tejedor Alberto del
Published: July 2021

Fruto de un estudio histórico-cultural sobre el lugar subalterno que ocuparon los vendedores ambulantes entre los siglos XVI y XVII, este artículo analiza las ambiguas significaciones con las que fueron retratados en diferentes campos, y muy singularmente en la literatura, que los asoció a embaucadores, charlatanes, vagabundos, placeras apicaradas, emigrantes miserables y minorías étnico-religiosas. Sin embargo, y a pesar del estigma, sus formas de expresión y especialmente sus pregones cristalizaron como género folclórico-literario, conjugando algunos de los elementos de la cultura cómica popular típica del mundo de la plaza, las ferias y la fiesta.
CARLOS II Y EL PAPADO: LAS NEGOCIACIONES DE UNA LIGA DE ITALIA CONTRA LUIS XIV (1674-1684)
Authors: Mesa Coronado María del Pilar
Published: July 2021

El presente estudio se centra en uno de los factores esenciales de la política internacional de la Monarquía Hispánica en el Mediterráneo durante el reinado de Carlos II: la política expansionista de Luis XIV. La Monarquía Hispánica intentó mantener la presencia española en Italia frente a las tentativas de Luis XIV con el fin de evitar su alianza con la Santa Sede y los potentados italianos. De este modo, se analizarán las negociaciones que los embajadores españoles llevaron a cabo con el Papado para acordar una Liga de Italia contra el rey francés.
50 AÑOS DE ORGULLO. UN REPASO ESCRITO Y VISUAL POR LA HISTORIA DEL MOVIMIENTO LGTBIQ+ EN ESPAÑA
Authors: Villena Espinosa Rafael
Published: July 2021

En 1970 se aprobaba en España la Ley de Peligrosidad Social que condenaba penalmente las relaciones homosexuales. Ese mismo año, en diversas ciudades de Estados Unidos, se celebraban las primeras marchas del orgullo en recuerdo de la revuelta de Stonewall (1969), que tardarían siete años en encontrar su réplica en nuestro país (Barcelona, 1977). Así, 2017, 2019, 2020 son fechas en las que resuenan décadas de lucha en la historia del activismo LGTBIQ+. A propósito de tales conmemoraciones, se propone un balance historiográfico con las aportaciones recientes más significativas, un estado de la cuestión en el que debe incluirse también la serie de televisión Nosotrxs somos como relato visual histórico de ese nuevo movimiento social.

La Virgen con Niño y ángeles músicos. Connotaciones sexuadas en el imaginario musical medieval
Authors: Lorenzo Arribas Josemi
Published: July 2021

La dicotomía “cuerpo/mente” es una antigua taxonomía tradicional utilizada por el patriarcado para jerarquizar a los seres humanos. En el campo de la música, este emparejamiento se trasladó a la división entre instrumentos de cuerdas e instrumentos de viento. La Edad Media lo resignificó a través del iconograma de la Virgen con Niño rodeada por ángeles tañendo instrumentos musicales, en su mayor parte de “música baja”. Hay razones de naturaleza bióloga, fisiológica, mítico-existencial, simbólica, musical y antropológica que justifican esta división arbitraria aplicada a las capacidades musicales de varones y mujeres. Tal vez su primera manifestación iconográfica se encuentra en una portada decorada (siglo XIII) del monasterio de Santa María de Carracedo (León).
La guerra medieval a través de su registro arqueológico: el asedio al castillo santiaguista de Montizón (1465-1467)
Authors: Gallego Valle David
Published: July 2021

En este trabajo queremos reconstruir el asedio que se dio en el castillo de Montizón (Villamanrique, Ciudad Real) entre 1465 y 1467, usando una metodología que combina los estudios arqueológicos y el análisis de las fuentes documentales. En este sentido, este texto se enmarca en una corriente de investigación aún novedosa en España como es la denominada “arqueología del combate”, vertiente de los estudios sobre la materialidad de la guerra que está mucho más consolidada dentro de los ámbitos académicos anglosajones. Los hechos que aquí se analizan se encuadran en la guerra que se produjo entre el infante Alfonso de Ávila y su tío Enrique IV a raíz de la “Farsa de Ávila” de 1465, donde el monarca es depuesto a favor de su sobrino por una facción muy importante de la nobleza de Castilla, en la que entró en juego, además, el control de la orden de Santiago entre diversos linajes nobiliarios. Entre estas luchas por el poder destacó, por su virulencia, el campo de operaciones que se dio a ambos lados de Sierra Morena y que enfrentó a los Manrique, entre otros, con los Lucas de Iranzo, siendo la pugna por la encomienda y castillo de Montizón uno de los puntos clave de estos hechos.

Más allá del Báltico: la embajada del Almirante de Aragón (1597) y las problemáticas del frente danubiano
Authors: Conde Pazos Miguel
Published: July 2021

La embajada a Polonia del Almirante de Aragón de 1597 supuso un punto de inflexión en las relaciones entre la Monarquía Hispana y la corona de Polonia-Lituania. La difícil elección de Segismundo III como rey en 1587 no fue reconocida por Felipe II, quien durante años siguió apoyando a su sobrino, el archiduque Maximiliano, en sus aspiraciones al trono polaco. Sin embargo, a partir de 1596 y por influjo de la diplomacia papal, las dos cortes iniciaron un progresivo acercamiento, que culminó con esta embajada. En este artículo describimos algunos aspectos de la misión, centrando nuestra atención en la compleja situación interna de Polonia-Lituania y en una serie de cuestiones en torno al frente danubiano que, olvidadas por la problemática báltica, no han despertado tanto la atención de los historiadores.

Authors: Bartolomé Bartolomé Juan Manuel
Published: July 2021

Tomando como fuente primordial los protocolos notariales y los inventarios de bienes, el objetivo fundamental es analizar, mediante una metodología cuantitativa y cualitativa, los patrimonios y las permanencias y los cambios en la cultura material, condiciones de vida y apariencias de las familias campesinas de las localidades periféricas castellanas, Miranda de Ebro y su jurisdicción tratando de averiguar las continuidades y la llegada de novedades en los interiores domésticos y en las apariencias externas, a finales del Antiguo régimen, y también las analogías y diferencias con los campesinos del interior castellano leonés. ¿Al ser poblaciones más próximas a Europa y en zonas de transición, la llegada de la modernidad fue más temprana que en las familias del interior? La principal conclusión es que las familias de la zona norte castellana presentarán en el periodo analizado rasgos distintivos respecto al campesinado de las zonas del interior castellano leonés.
El archivo señorial de Paracuellos, un fondo documental de los marqueses de Malagón
Authors: Sánchez González Antonio
Published: July 2021

Los Pardo-Tavera, mariscales de Castilla en la Edad Moderna, compraron a la Corona dos antiguas encomiendas militares a mediados del siglo XVI que se convirtieron en señoríos estables, caso de Paracuellos de Jarama y Malagón, este último convertido en marquesado en 1599. Más tarde, los señores de Paracuellos y marqueses de Malagón entroncaron, a partir del siglo XVII, con otras casas nobiliarias peninsulares, pasando sus archivos a incorporarse sucesivamente, primero en el siglo XVIII, al de los duques de Santisteban del Puerto y, definitivamente en 1818, al de los duques de Medinaceli. El objetivo de este artículo es dar a conocer el archivo de los señores de Paracuellos, desde su formación hasta nuestros días, tratando de sus escrituras, de su organización documental y su disposición actual, para facilitar el camino a futuras investigaciones sobre estos fondos. Para ello, metodológicamente, no solo hemos trabajado en el fondo documental conservado en el Archivo Ducal de Medinaceli aquí objeto de estudio, revisando sus inventarios y analizando las marcas dorsales de cada pieza documental, sino también en la documentación de referencia que se conserva en otros archivos.
Los Sitios Reales durante el Trienio Liberal: la cesión de una parte del patrimonio real a la nación
Authors: Labrador Arroyo Félix
Published: July 2021

El triunfo del pronunciamiento del coronel Riego en Cabezas de San Juan supuso cambios en el patrimonio real. Los liberales lo consideraban un anacronismo que debía de ser abolido, siendo la nación la nueva titular de sus derechos y bienes y la que señalaría los espacios destinados o reservados al monarca y a su familia necesarios para el decoro y desempeño de sus funciones, de acuerdo con lo dispuesto en la Constitución de 1812. Además, en un contexto de necesidad de la hacienda nacional estos espacios, una vez nacionalizados generarían una importante fuente de ingresos. En este trabajo, a través de documentación primaria, fundamentalmente del Archivo General de Palacio, analizaremos el proceso de cesión por parte de la corona de una serie de bienes y espacios reales a la nación, —nada despreciables— las consideraciones que este proceso generó entre los liberales y los cambios que está cesión produjo en la gestión del patrimonio real. Sin embargo, el fin del Trienio impidió que se consolidase una línea de actuación concreta sobre el real patrimonio
El Grito del Ejército y La España Militar: dos ejemplos de prensa castrense
Authors: Cameno Mayo Diego
Published: July 2021

La prensa militar proporciona gran cantidad de información acerca de la situación del instituto armado de un país en un periodo concreto. Su interés radica en que son escritos por militares y para militares, permitiendo al lector conocer cuáles eran los temas que más preocupaban a los soldados del momento. Este trabajo pretende analizar unos periódicos concretos, ligados a la figura del capitán Eduardo Perrotte, quien los bautizó como El Grito del Ejército y La España Militar, publicados en un periodo determinado (la Regencia de Espartero, tras finalizar la Primera Guerra Carlista), buscando conocer la manera en que una parte del ejército se veía a sí misma y lo plasmaba por escrito para que todos lo leyesen, en un contexto de posguerra civil, en la que las tropas no se sentían cómodas con ciertas medidas del gobierno (muy criticado en estos periódicos) y con el tratamiento que recibían por parte de una sociedad a la que habían defendido, derramando su sangre, entre 1833 y 1840.
On the roads of Spain: Andrei Vizanti, the first Romanian student in Madrid (1865-1868)
Authors: Oncescu Iosif Iulian
Published: July 2021

En el proceso de formación de las élites rumanas modernas, especialmente después de la Unificación de los Principados Rumanos (1859), dos de los jóvenes estudiantes rumanos llegaron a la lejana España. Es el caso de Andrei Vizanti y Ştefan Vârgolici, quienes fueron seleccionados como académicos del estado rumano en el otoño de 1864 para estudiar en la Universidad Central (Madrid, España), por un período de cuatro años. De estos, sólo Andrei Vizanti permaneció en la capital española, mientras que Ştefan Vârgolici, después de una breve parada en Madrid (en 1865), partió para París. Después de tres años de estudio (1865-1868), en junio de 1868, Andrei Vizanti obtuvo el título de Licenciado en La Facultad de Filosofía y Letras de la Universidad Central, sendo el único graduado de una universidad española hasta la segunda mitad del siglo XX.
La Monarquía española en el actual ceremonial de apertura de la legislatura parlamentaria (1979-2020)
Authors: Luján Oriol
Published: July 2021

Este texto pretende reflexionar sobre la presencia de la Monarquía en las aperturas de las legislaturas parlamentarias de las últimas décadas en la España democrática (1979-2020), a fin de demostrar que, lejos de ser una novedad reciente, parte sustancial de la escenificación del actual rito tiene su origen en el franquismo. Además, el artículo aspira a evidenciar la incidencia que tienen los medios de comunicación en el desarrollo de una ceremonia condicionada por su exposición pública y que se ha ido transformando hasta convertirse, a día de hoy, en un acto cuya puesta en escena no solo magnifican los monárquicos —empezando por el propio rey— sino incluso los propios detractores de la institución. Ello también ayuda a propiciar una dimensión más politizada de la Corona, colocándola en el centro del debate político como la institución central del sistema constitucional español.

AIM: To investigate the association of axial length (AL) and ocular factors on AL elongation.
METHODS: A retrospective chart review of patients who underwent two or more AL examinations for more than two years. Totally 4 groups were divided according to initial AL (<24 mm, 24-26 mm, 26-28 mm, ≥28 mm). Initial fundus photograph was used to find risk factors associated AL elongation.
RESULTS: The mean age of the patients was 47.21±7.79y. AL remained almost unchanged in the groups with AL<24 mm and 24≤AL<26 mm. On the contrary, AL increased by 0.011 mm/y in the group with 26≤AL<28 mm and 0.035 mm/y in the group with AL≥28 mm (P<0.001). In high myopia, AL elongation increased in eye with longer AL (r=0.003, P=0.024), female gender (r=0.014, P=0.019), eye with larger peripapillary chorioretinal atrophic area (r=0.002, P=0.019), and smaller vascular arcade angle (r=-0.004, P=0.006). The risk of elongation 0.03 mm/y in high myopia was increased in female gender (P=0.040), and gradually increased in eye with large peripapillary chorioretinal atrophy area (P<0.01).
CONCLUSION: AL elongate significantly in the eye with longer AL, female gender, and the eye with larger atrophic area and smaller arcade angle on fundus photography.

Age-related eye diseases, including cataract, glaucoma, diabetic retinopathy (DR), and age-related macular degeneration (AMD), are the leading causes of vision loss in the world. Several studies have shown that the occurrence and development of these diseases have an important relationship with oxidative stress in the eye. The Keap1-Nrf2-ARE pathway is a classical pathway that resists oxidative stress and inflammation in the body. This pathway is also active in the development of age-related eye diseases. A variety of drugs have been shown to treat age-related eye diseases through the Keap1-Nrf2-ARE (Kelch-like ECH-Associating protein 1- nuclear factor erythroid 2 related factor 2-antioxidant response element) pathway. This review describes the role of oxidative stress in the development of age-related eye diseases, the function and regulation of the Keap1-Nrf2-ARE pathway, and the therapeutic effects of drugs associated with this pathway on age-related eye diseases.
Psicología en el siglo XXI
Authors: Cárdenas P. Fernando
Published: July 2021

El enorme avance en el desarrollo científico-tecnológico característico de las últimas décadas ha ocasionado grandes cambios en el pensamiento cotidiano y en la aproximación a los problemas teóricos. El que más ha afectado a la Psicología es la posibilidad de explicar los procesos psicológicos en términos neurobiológicos. Ya desde el nacimiento mismo de la disciplina en 1864, con los trabajos de Paul Broca, según algunos, o en 1879, con la creación del primer laboratorio de Psicología por Wilhelm Wundt, según otros, hubo una tímida tendencia a la adopción de posiciones materialistamonistas para el estudio de los fenómenos psicológicos. Pero solo hasta hace relativamente poco se comenzaron a dar pasos certeros en esta dirección, pues no existían las herramientas tecnológicas, matemáticas e informáticas necesarias para la integración teórica de los datos obtenidos en la experimentación. En este escrito se hace inicialmente una breve contextualización del origen de la Psicología, intentando definir sus problemas principales y las metodologías propuestas en un comienzo y a continuación se ofrecen algunos ejemplos de la forma en que los desarrollos tecnológicos en neurociencia se han venido integrando al campo de la Psicología; por último, se plantea que el futuro de la disciplina parece estar construyéndose a partir de la inclusión de sus problemas, preguntas y metodologías en el marco de la neurociencia.
A Novel Multi-Level Pyramid Co-Variance Operators for Estimation of Personality Traits and Job Screening Scores
Authors: Telli Hichem , Sbaa Salim , Bekhouche Salah Eddine , Dornaika Fadi , Taleb-Ahmed Abdelmalik , López Miguel Bordallo
Published: July 2021

Recently, automatic personality analysis is becoming an interesting topic for computer vision. Many attempts have been proposed to solve this problem using time-based sequence information. In this paper, we present a new framework for estimating the Big-Five personality traits and job candidate screening variable from video sequences. The framework consists of two parts: (1) the use of Pyramid Multi-level (PML) to extract raw facial textures at different scales and levels; (2) the extension of the Covariance Descriptor (COV) to fuse different local texture features of the face image such as Local Binary Patterns (LBP), Local Directional Pattern (LDP), Binarized Statistical Image Features (BSIF), and Local Phase Quantization (LPQ). Therefore, the COV descriptor uses the textures of PML face parts to generate rich low-level face features that are encoded using concatenation of all PML blocks in a feature vector. Finally, the entire video sequence is represented by aggregating these frame vectors and extracting the most relevant features. The exploratory results on the ChaLearn LAP APA2016 dataset compare well with state-of-the-art methods including deep learning-based methods.
A Multi-Feature Motion Posture Recognition Model Based on Genetic Algorithm
Authors: Liu Yuanguo , Wu Ying
Published: July 2021

The effect of motion posture recognition hinges on the accurate description of motion postures with effective feature information. This study introduces Wronskian function to improve the denoising ability of visual background extractor (ViBe) algorithm, and thus acquires relatively clear motion targets. Then, a multi-feature fusion motion posture feature model was developed based on genetic algorithm (GA). Specifically, GA was called to optimize and fuse the extracted feature information, while a fitness function was constructed based on the mean variance ratio, and used to select the feature information with high inter-class discriminability. Taking support vector machine (SVM) as the classifier, a multi-class classifier was designed by one-to-one method for the classification and recognition of motion postures. Through experiments, our model was proved highly accurate in motion posture recognition.
Efficient Multi-Organ Multi-Center Cell Nuclei Segmentation Method Based on Deep Learnable Aggregation Network

Published: July 2021

Automated cell nuclei delineation in whole-slide imaging (WSI) is a fundamental step for many tasks like cancer cell recognition, cancer grading, and cancer subtype classification. Although numerous computational methods have been proposed for segmenting nuclei in WSI images based on image processing and deep learning, existing approaches face major challenges such as color variation due to the use of different stains, the various structures of cell nuclei, and the overlapping and clumped cell nuclei. To circumvent these challenges in this article, we propose an efficient and accurate cell nuclei segmentation method based on deep learning, in which a set of accurate individual cell nuclei segmentation models are developed to predict rough segmentation masks, and then a learnable aggregation network (LANet) is used to predict the final nuclei masks. Besides, we develop cell nuclei segmentation software (with a graphical user interface—GUI) that includes the proposed method and other deep-learning-based cell nuclei segmentation methods. A challenging WSI dataset collected from different centers and organs is used to demonstrate the efficiency of our method. The experimental results reveal that our method obtains a competitive performance compared to the existing approaches in terms of the aggregated Jaccard index (AJI=89.25%) and F1-score (F1=73.02%). The developed nuclei segmentation software can be downloaded from https://github.com/loaysh2010/Cell-Nuclei-Segmentation-GUI-Application.
Identification and Analysis of Limb Rehabilitation Signal Based on Wavelet Transform
Authors: Zhang Chao , Zou Ji , Ma Zhongjing
Published: July 2021

The development of science and technology has promoted the extensive application of surface electromyography (sEMG) collection technique in real-time exercise testing, assistive judgment of rehabilitation therapy, and assessment of intelligent artificial limb application. However, there is a severe lacking of studies on pattern recognition based on effective signal, and evaluation of limb rehabilitation status. To make up for the gap, this paper explores the identification and analysis of limb rehabilitation signal based on wavelet transform. Specifically, the authors detailed the basic flow of sEMG signal generation in motor unit during limb rehabilitation exercise, and proposed a limb EMG pattern recognition method. Then, support vector machine (SVM) was selected to recognize the pattern of the EMG signal extracted from the limb rehabilitation exercise of patients, and to judge the rehabilitation status. Finally, wavelet thresholding was combined with total variation denoising (TVD) to effectively remove the noise from EMG signal. The proposed method was proved effective through experiments.
Forest Fire Recognition Based on Feature Extraction from Multi-View Images

Published: July 2021

Forest fire recognition is important to the protection of forest resources. To effectively monitor forest fires, it is necessary to deploy multiple monitors from different angles. However, most of the traditional recognition models can only recognize single-source images. The neglection of multi-view images leads to a high false positive/negative rate. To improve the accuracy of forest fire recognition, this paper proposes a graph neural network (GNN) model based on the feature similarity of multi-view images. Specifically, the correlations (nodes) between multi-view images and library images were established to convert the input features of graph nodes into the correlation features between different images. Based on feature relationships, the image features in the library were updated to estimate the node similarity in the GNN model, improving the image recognition rate of our model. Furthermore, a fire area feature extraction method was designed based on image segmentation, aiming to simplify the complex preprocessing of images, and effectively extract the key features from images. By setting the threshold in the hue-saturation-value (HSV) color space, the fire area was extracted from the images, and the dynamic features were extracted from the continuous frames of the fire area. Experimental results show that our method recognized forest fires more effectively than the baselines, improving the recognition accuracy by 4%. In addition, the multi-source forest fire data experiment also confirms that our method could adapt to different forest fire scenes, and boast a strong generalization ability and anti-interference ability.
Signed Convex Combination of Fast Convergence Algorithm to Generalized Sidelobe Canceller Beamformer for Multi-Channel Speech Enhancement
Authors: S Siva Priyanka , T Kishore Kumar
Published: July 2021

In speech communication applications such as teleconferences, mobile phones, etc., the real-time noises degrade the desired speech quality and intelligibility. For these applications, in the case of multichannel speech enhancement, the adaptive beamforming algorithms play a major role compared to fixed beamforming algorithms. Among the adaptive beamformers, Generalized Sidelobe Canceller (GSC) beamforming with Least Mean Square (LMS) Algorithm has the least complexity but provides poor noise reduction whereas GSC beamforming with Combined LMS (CLMS) algorithm has better noise reduction performance but with high computational complexity. In order to achieve a tradeoff between noise reduction and computational complexity in real-time noisy conditions, a Signed Convex Combination of Fast Convergence (SCCFC) algorithm based GSC beamforming for multi-channel speech enhancement is proposed. This proposed SCCFC algorithm is implemented using a signed convex combination of two Fast Convergence Normalized Least Mean Square (FCNLMS) adaptive filters with different step-sizes. This improves the overall performance of the GSC beamformer in real-time noisy conditions as well as reduces the computation complexity when compared to the existing GSC algorithms. The performance of the proposed multi-channel speech enhancement system is evaluated using the standard speech processing performance metrics. The simulation results demonstrate the superiority of the proposed GSC-SCCFC beamformer over the traditional methods.
Study of Survivorship and Functional Outcome of Total Hip Arthroplasty in Avascular Necrosis of Femur Head
Authors: Sarkar Mehul , Wagh Nitin , Pangavane Sandeep
Published: July 2021

Osteonecrosis of the femoral head is not a specific diagnostic entity, but rather the final common pathway of a series of derangements that produce a decrease in blood flow, leading to cellular death within the femoral head. It can present with a number of clinical manifestations. The most common complaint is a deep, intermittent, throbbing pain in the groin region which has an insidious onset. In the early stages, prophylactic measures are used to prevent further progression of the disease. When the patient is diagnosed in later stages, the collapse and distortion of the femoral head can be seen, for which a reconstructive procedure is the treatment of choice. The goals of total hip arthroplasty are to relieve pain, to provide motion with stability and to correct deformity so that they are able to return to their normal daily activities. Total hip arthroplasty can be the first treatment of choice. especially in the advanced stages of hip osteonecrosis, or can be reserved as a salvaging procedure when other more conservative treatments fail. Total Hip Arthroplasty is a good modality of treatment for patients with very poor pre-surgical functional scores combined with an excellent long term survival of the cement-less implants.

Published: July 2021

Background: Temporal bone imaging has always been a challenge. Though infections and trauma are the most common pathologies encountered; a wide range of neoplasms affect this region which can become a serious threat if overlooked. Computed Tomography (CT) plays a crucial role in diagnosis and characterization of these neoplasms. It is very helpful to evaluate the extent of the lesion and involvement of adjacent structures, helping to decide appropriate management. Aims and Objectives: The purpose of our study was primarily to evaluate various neoplasms in the temporal region based on CT findings in patients presenting to the radiology department in a tertiary care centre. Materials and Methods: The prospective study done over a period of 2 years in the Department of Radio-diagnosis at Dr. Vasantrao Pawar Medical College, Hospital and Research Centre, Nashik included 26 patients with neoplasms involving the temporal region. CT scan of all these patients was performed on Siemens Somatom Perspective (128 slice). The imaging findings were correlated with histopathological and surgical findings wherever available. Results: The study comprised of 26 patients in which bulk of the patient's i.e. 42% had features of vestibular schwannoma on imaging. Glomus tumour and cerebellopontine angle epidermoid cyst found in 15% and 11% of patients, respectively were the other common lesions. Neoplasms were most common in the age group of 41 to 50 years. There was female preponderance (62%) amongst patients. Headache and hearing loss were the most common complaint. Conclusion: We can ascertain from this study that neoplasms in the temporal region show characteristic findings on CT imaging. These imaging characteristics coupled with other imaging and clinical findings help us to achieve an accurate diagnosis. Imaging techniques enables a reliable non-invasive assessment of these neoplasms.

Published: July 2021

Background: Hyponatremia is the most prevalent electrolyte abnormality worldwide, presenting at even higher rates in the ICU setting. It is one of the leading causes of metabolic encephalopathy and can present with a myriad of neurological features. It is defined by a serum sodium level <135 mEq/L. The present study is designed to evaluate the neurological symptoms in a patient with hyponatremia and to correlate them with the degree of hyponatremia. Aims and Objectives: 1) To study the neurological manifestations in ICU patients found to have hyponatremia 2) To study the correlation between neurological manifestations and serum sodium level. Materials and Methods: This is Prospective Observational study of 2 years duration in which 90 patients were studied with the following criteria: Age â‰¥18 years, either sex admitted in the ICU having sodium Level of < 135 mMol/L on admission. A thorough neurological examination including Mini Mental Status Examination (MMSE) and Glasgow Coma Scale (GCS) was done at presentation. The data was then analyzed. Results: There was a male predominance (64.44%) amongst the study population. Most patients belonged to the age group of 51-60 years (73.3%) followed by > 60 years (31.1%). Disorientation (41.11%) was the most common neurological features followed by drowsiness (31.11%).Maximum number (48.7%) of patients having mild hyponatremia were asymptomatic. At presentation, most had a normal Mini Mental Status Examination (MMSE) score (28.89%) followed by moderate cognitive impairment (27.78%), GCS scores â‰¥13 was seen in 56.67% population followed by GCS 9-12 (41.11 %). 2 (2.2%) patients succumbed in the study population. Conclusion: Hyponatremia is a common electrolyte abnormality causing significant morbidity and mortality, especially in the older age group. It is one of the leading causes of metabolic encephalopathy. As it can be asymptomatic in the initial stages, and is treatable, it should evaluated in all patients with subtle as well as overt neurological signs to prevent further neurological deterioration. MMSE scoring is a useful tool for neurological assessment in hyponatremia.

Authors: Diwan Anand Gajanan
Published: July 2021

Sunflower Syndrome (Self-induced Photosensitive Epilepsy) is a rare epileptic disorder of childhood; characterized by stereotyped behavior; comprising of obsessively seeking out a light source, staring at the light source, and waving one hand in the front of their eye(s). It is a rare form of photosensitive epilepsy. The exact pathogenesis is unknown but the anatomical substrate of origin may be cingulate circuit. Sunflower syndrome is poorly characterized in medical literature and is often misdiagnosed in the neurology clinics. Identifying this specific syndrome is important for effective prevention by blue glasses and management with broad spectrum anti-epileptics medications. This is a single case report of a young boy; with electro-clinical data.

Published: July 2021

As redes sociais são como teias de conexões pessoais que misturam o público e o privado. Será neste contexto que o presente artigo propõe a análise de como as divulgações de imagens e conteúdos nas redes sociais se mostram eivadas de afetos e desafetos, desencadeando o que o estudo denomina de alienação parental digital, quando resta evidenciada a manipulação de imagens e palavras pelo alienador para atingir a imagem do alienado. A caracterização de um novo formato de alienação parental foi proposta como um fenômeno advindo com a pós-verdade. Diante deste contexto, o trabalho avalia como é possível a aplicação dos deveres fundamentais nas relações familiares como meio de controle da alienação digital. O tema é estudado tomando por base a necessária interface entre direito, psicanálise e sociologia.

O objetivo principal deste artigo é tratar sobre a oitiva de menores nos crimes de estupro de vulnerável a partir da analogia entre a resolução 17/2002 da Corte Interamericana de Direitos Humanos (CIDH) e a Lei 13.431 de 04 de abril de 2017 (Lei do Depoimento Especial). Em razão da dispensa da oitiva da vítima menor ou a tomada de depoimento de forma imprópria, a Lei n. 13.431/17 normatiza e organiza o sistema de garantia de direitos da criança e do adolescente vítima de violência - pautado na doutrina da proteção integral, nos termos do art. 227 da Constituição Federal, da Convenção sobre os Direitos da Criança e seus protocolos adicionais, da Resolução no 20/2005 do Conselho Econômico e Social das Nações Unidas e de outros diplomas internacionais, regulamentando o depoimento especial.
De que lado caminha a justiça restaurativa? Algumas reflexões sobre sua implementação no cenário brasileiro.
Authors: Saggioro Davis Renata
Published: July 2021

Nos últimos anos, a justiça restaurativa vem sendo alçada como um modelo alternativo de resolução de conflitos em contraposição ao sistema de justiça criminal, despertando, assim, o interesse e entusiasmo de diversos teóricos e aplicadores do Direito. No entanto, propostas alternativas ao encarceramento e ao sistema penal de forma geral desafiam tratamento cauteloso na medida em que, como demonstram estudos criminológico-críticos, chave de leitura do presente estudo, experiências reformistas implicaram no alargamento das redes de controle do poder punitivo. Partindo então dessa hipótese, a proposta deste trabalho é problematizar a ascensão da justiça restaurativa como modelo de justiça capaz de enfrentar o poder punitivo e suas agências de controle – tal como se propõe – sobretudo no contexto brasileiro em que o poder judiciário exerce o protagonismo em sua implementação. Para tanto, articular-se-á o referencial teórico-metodológico da criminologia crítica para analisar alguns pressupostos elementares da proposta restaurativa trazidos por autores consagrados nesse campo de estudo, assim como as normativas desenvolvidas em torno do instituto no nosso país.

Published: July 2021

Aim: The purpose of this study was to extract the lived experiences of working couples from marital conflicts.
Methods: This study was conducted with a qualitative approach using interpretive phenomenology. In this study, researchers interviewed 12 working couples with marital conflicts using purposeful sampling. Interviews were analyzed using interpretive phenomenology.
Findings: Analyzing the data from the interviews led to the identification of the 14 main themes: financial conflict, inappropriate interactions in social media, lack of participation in house chores, ineffective communication, inability in reciprocal empathy and expression,  lack of time management,  conflict of roles and responsibilities, cognition vulnerability, adherence to gender stereotypes, inability to manage tasks at job and work environment, work-family conflict, power struggles, ultra-personal destructive factors and belief and ethical problems, 55 primary and 12 secondary themes in the lived experiences of working couples from marital conflicts.
Conclusion: A dual-career family is a place where couples are more likely to enter into marital conflicts if they do not realize fairness in various areas of family and work. The results of the present study showed that the families of career couples may be a high-risk group in terms of conflict, and this factor indicates the need for a negotiating role in the relationship between this type of couple. This highlights the need for special couple therapy for these couples. The results of the present study also showed that ineffective communication, cognitive vulnerability, work-family interaction, financial conflict and lack of participation in home affairs, were the most common causes of marital conflict; so it is recommended that preventive and educational programs for couples include the abovementioned factors.
