RESUMO

O Porto do Recife recebe uma grande quantidade de navios de vários tipos e de muitas partes do mundo, podendo trazer espécies exóticas incrustadas no casco ou em água de lastro. O objetivo do presente estudo foi registrar e analisar os padrões de recrutamento de espécies bentônicas sésseis, assim como investigar uma possivel introdução de espécies bentônicas exóticas e criptogênicas em uma área portuária com grande fluxo de navios. Utilizaram-se placas de metal galvanizado para estudo do recrutamento de animais sésseis e sedentários em três pontos amostrais no porto, com três réplicas cada, totalizando nove pontos, durante seis meses (outubro de 2010 a março de 2011), considerado como período seco. As placas de recrutamento foram retiradas a cada 30 dias durante seis meses. As principais espécies de acordo com a área de cobertura foram Mytella charruana (72%) e Amphibalanus improvisus (22%) e espaços vazios (7,5%). Não houve diferença significativa quando comparadas as três estações no porto do Recife, sendo encontradas diferenças quando comparadas os dados das áreas de cobertura das espécies mais abundantes no recrutamento. Foram elas: Clytia gracilis, Obelia dichotoma, M. charruana e A. improvisus.

 

ABSTRACT

The Port of Recife receives a large number of vessels of various types and from many parts of the world, and can bring exotic species encrusted hull or in ballast water. The aim of this study was to record and analyze the patterns of recruitment of sessile benthic species, as well as investigating a possible introduction of exotic and cryptogenic benthic species in a port area with great flow vessels. We used galvanized metal plates to study the recruitment of sessile and sedentary animals at three stations in the harbor, with three replicas each, totaling nine points, six months (October 2010 to March 2011), considered the dry . The plates recruitment were taken every 30 days for six months. The main species according to coverage area were Mytella charruana (72%) and Amphibalanus improvisus (22%) and voids (7.5%). There was no significant difference when comparing the three stations in the Port of Recife, differences were found when comparing the coverage areas of most abundant species in recruitment. They were: Clytia gracilis, Obelia dichotoma, M. charruana and A. improvisus.
Preparar al maestro para el cambio educativo

RESUMEN

Existe una toma de conciencia en relación con la necesidad de producir cambios en la educación; pero no está suficientemente claro por qué y para qué cambiar, qué, cómo y quién debe cambiar. Aparece siempre en el horizonte la amenaza de nuevos dogmatismos, y sobre todo de ejercicios tradicionales de cambio que son más deseos que realidades.

Repensar la formación de los maestros implica pensar en los contenidos de la formación, en los que enseñará, cómo los transmitirá, (incorporando las TIC), y el tipo de prácticas para trabajar en el aula, con la familia y la gestión en la escuela, pero también cómo debe ser el proceso formativo para que estén en capacidad de promover el cambio educativo.

El modelo de formación debe poner el énfasis en que el aprendizaje ocurre en una relación entre el profesor y los estudiantes, donde intervienen dos aspectos cruciales, uno es cognitivo: el conocimiento, dominio de la materia que enseña, y el otro es emocional: la capacidad para poder interpretar el mundo interno de los alumnos.

El Proyecto Con infinito amor pone el énfasis en propiciar la participación de los estudiantes, motivarlos de manera que sepan reflexionar y orientarse acertadamente ante su realidad.

 

ABSTRACT

There is a growing awareness of the need to bring about change in education, but it is not sufficiently clear why and what to change, what, how and who should change. The threat of new dogmatisms always appears on the horizon, and above all of traditional exercises of change that are more desires than realities.

Rethinking teacher training implies thinking about the contents of the training, what they will teach, how they will transmit them (incorporating ICT), and the type of practices to work in the classroom, with the family and school management, but also what the training process should be like so that they are able to promote educational change.

The training model should emphasize that learning occurs in a relationship between the teacher and the students, where two crucial aspects are involved, one is cognitive: knowledge, mastery of the subject taught, and the other is emotional: the ability to interpret the inner world of the students.

The Con infinito amor project emphasizes the participation of students, motivating them so that they can reflect and orient themselves correctly in the face of their reality.

Introduction: Haze is a recurrent problem in Southeast Asia. Exposure to haze is linked to ophthalmic,
respiratory and cardiovascular diseases, and mortality. In this study, we investigated the role of
demographic factors, knowledge and perceived risk in influencing protective behaviours during the
2013 haze in Singapore.
Methods: We evaluated 696 adults in a cross-sectional study. Participants were sampled via a
2-stage simple random sampling without replacement from a large residential district in Singapore in
2015. The questionnaire measured the participant’s knowledge, perceived risk and behaviours during
the Southeast Asian haze crisis in 2013. Reliability and validity of the questionnaire were assessed
using comparative fit index (≥0.96) and root mean square error of approximation (≤0.05). We
performed structural equation modelling to examine the relationship between the hypothesised factors
and protective behaviours.
Results: More than 95% of the individuals engaged in at least 1 form of protective behaviour.
Knowledge was strongly associated with protective behaviours via direct effect (β=0.45, 95%
CI 0.19–0.69, P<0.001) and indirect effect through perceived risk (β=0.18, 95% CI 0.07–0.31, P=0.002).
Perceived risk was associated with protective behaviours (β=0.28, 95% CI:0.11–0.44, P=0.002). A
lower household income and ethnic minority were associated with protective behaviours. A lower
education level and smokers were associated with lower knowledge of haze. A higher education and
ethnic minority were associated with a lower perceived risk. Wearing of N95 masks was associated
with other haze-related protective behaviours (β=0.24, 95% CI 0.08–0.37, P=0.001).
Conclusion: Knowledge was associated with protective behaviours, suggesting the importance of
public education. Efforts should target those of lower education level and smokers. The wearing of
N95 masks correlates with uptake of other protective behaviours.

Introduction: We report outcomes of patients with oesophageal cancer treated with neoadjuvant
chemoradiotherapy (NACRT) plus surgery or definitive chemoradiotherapy (chemoRT) at our institution.
Methods: We retrospectively reviewed patients who underwent chemoRT from 2005 to 2017. The
primary outcome was overall survival (OS). Secondary outcomes were disease-free survival (DFS)
and toxicities.
Results: We identified 96 patients with median age of 64 years and squamous cell carcinoma in
82.3%. Twenty-nine patients (30.2%) received NACRT plus surgery, 67 patients (69.8%) received
definitive chemoRT. Median follow-up was 13.5 months. The 3/5-year OS were 26.4%/13.4%,
and 59.6%/51.6% in the definitive chemoRT and NACRT plus surgery groups, respectively. The
3/5-year DFS were 19.3%/12.3%, and 55.7%/37.2% in the definitive chemoRT and NACRT plus
surgery groups, respectively. NACRT plus surgery significantly improved OS (hazard ratio [HR]
0.40, 95% confidence interval [CI] 0.22–0.72, P<0.01) and DFS (subhazard ratio [SHR] 5.21, 95
CI 1.20–22.7, P=0.03). Multivariable analysis for OS in the definitive chemoRT group indicated
stage (1–2 vs 3–4a; HR 2.17, 95% CI 1.15–4.11, P=0.02) and feeding tube (no tube versus tube; HR
1.85, 95% CI 1.00–3.43, P=0.05) as significantly associated with OS. The cumulative incidence of local
recurrence was significantly higher in the definitive chemoRT group (SHR 5.21, 95 CI 1.2022.7,
P=0.03). Nineteen patients (65.5%) had postoperative complications.
Conclusion: NACRT plus surgery improved OS and DFS. However, in view of treatment-related
complications, careful selection of patients is warranted. With the predominant histology of our cohort
being squamous cell carcinoma (SCC), our results may be more re levant for those with SCC.

El linfoma de células T epidermotropo agresivo CD8+ o linfoma de Berti es un subtipo infrecuente de los linfomas primarios cutáneos, descripto en 1999. Aún se considera una entidad provisional en la última clasificación de linfomas cutáneos primarios de la Organización Mundial de la Salud. Predomina en los hombres adultos y se manifiesta con pápulas, placas hiperqueratósicas y tumores ulcerados, diseminados y de inicio agudo. En la histopatología, es característica la presencia de un infiltrado de linfocitos atípicos medianos CD8+, con epidermotropismo de patrón pagetoide. Tiene un comportamiento agresivo y es de mal pronóstico, con una sobrevida a los 5 años menor del 40%. Si bien esta entidad es un reto terapéutico, el tratamiento inicial se basa en poliquimioterapia y/o trasplante de células hematopoyéticas.

Equity and certainty in contract law
Authors: Brand F
Published: July 2021

The role of abstract values such as equity and fairness in our law of contract has been the subject of controversy for a number of years. In 2002 the Supreme Court of Appeal took the position that these values do not constitute self-standing grounds for interfering with contractual relationships. Despite this being consistently maintained by the SCA in a number of cases, some High Court judges deviated from this position on the basis that they were permitted to do so by some minority judgments and obiter dicta in the Constitutional Court. The uncertainty thus created has fortunately now been removed by the judgment of the Constitutional Court in Beadica v The Trustees for the Time being of the Oregon Trust.
Agency in South Africa: Mapping its defining characteristics
Authors: Glover G
Published: July 2021

This article draws on contemporary trends in Anglo-American jurisdictions to propose a modernised analytical framework for agency law in South Africa. It first investigates the juridical basis of agency law, finding that the consensus is to see agency as a complex phenomenon that synthesises both internal consent and external power/liability models. Secondly, the article proposes certain essential conceptual features of agency, briefly discusses these features, and argues, with reference to comparative authority, how adopting these might facilitate a more complete understanding of agency in South Africa.

Authors: Fitriani Oryza Sativa , Suhatri Suhatri , Rivai Harrizul
Published: July 2021

Traditional medicinal ingredients originating from the Province of East Kalimantan (Indonesia) with the composition of meniran leaves (Phyllanthus niruri L.), cat whiskers leaves (Orthosiphon aristatus), ceplukan leaves (Physalis minima L.), and lempuyang emprit rhizome (Zingiberis amaricana Bl.) are used to help lower blood pressure by the local community. This study aimed to analyze the content of chemical compounds, determine the levels of chemical compounds, and the antihypertensive effect of these traditional medicinal ingredients. This traditional medicinal herb is made into a fine powder and then brewed with boiling water. Phytochemical screening and determination of levels of phytochemical compounds were carried out on these traditional medicinal ingredients. Testing the antihypertensive effect of these traditional medicinal ingredients was carried out on white male rats. The results of the qualitative analysis showed that the chemical compounds contained in the traditional medicinal ingredients were flavonoids, phenols, tannins, and carbohydrates. Quantitative analysis of the traditional medicinal ingredients showed that the content of flavonoid compounds was 0.6375%, phenolic compounds were 3.2412%, and tannin compounds were 0.6593%. Testing the antihypertensive effect of this traditional medicinal herb on rats can reduce systolic, diastolic, and arterial blood pressure. The conclusion is that this traditional medicinal herb contains phytochemical compounds that can help lower blood pressure in rats.
Arrhythmia Termination During Radiofrequency Delivery Improves Outcomes after Catheter Ablation for Persistent and Long Standing Persistent Atrial Fibrillation

Published: July 2021

Background

Achieving long-term successful outcomes with catheter ablation (CA) of persistent atrial fibrillation (PsAF) remains a challenge. Multiple attempts to determine effective ablation strategies besides the pulmonary veins (PV) were made but, so far, there is no agreed standard approach and no clear consensus as to which is the best one. Among the most frequently used techniques was ablation of complex atrial fractionated electrograms (CFAE) but studies showed contradictory results. The optimal procedural endpoint also needs further refinement.

Objectives

We sought to evaluate outcomes in regard to patient characteristics and procedural termination. We also aimed to assess whether continuation of antiarrythmic therapy in the blanking period (1 to 3 months after the procedure) influences long term results.

Methods

We enrolled consecutive patients with persistent and long-standing PsAF (LS-PsAF) who underwent one or more radiofrequency catheter ablations (RF CA) - pulmonary vein antral isolation (PVAI), followed by CFAE or resultant atrial tachycardia/flutter elimination, were retrospectively analyzed. Procedural objective was tachyarrhythmia (AF or resultant atrial flutters/tachycardias) termination (TT) to sinus rhythm (SR) during RF delivery. If after extensive substrate based or activation guided ablation sinus rhyhtm was not restored, conversion was performed with antiarrhythmic drugs (AAD), overdrive pacing or electrical shock. Screening for arrhythmia recurrence was performed via clinical interview and 48 hours Holter monitoring at 1,3 and 6 months and then every 6 months.

Results

The cohort included 94 patients (age 54.5±11.4, 67 (71%) males, CHADSVASc 2.3±2, 11 (12%) LS-PsAF) Acute restoration of sinus rhythm (SR) was achieved in 93.4% of the cases, 43% by ablation of CFAE or resultant atrial tachycardia/flutter(AT/AFL), 36.2% by electric cardioversion, 7.4% by chemical conversion, 3.1 % overdrive pacing, 3.7 % spontaneuous/mechanical. The long term success rate after a mean of 1.7±0.8 procedures was 59% at a mean follow-up period of 80±28 months. Freedom from AF was significantly higher when arrhythmia termination was obtained during RF delivery (p – 0.003). Short-term use of AAD in the blanking period did not lead to improved long term outcomes.

Conclusions

In patients with PsAF and LS-PsAF restoration of sinus rhyhtm during RF delivery for pulmonary vein isolation, ablation of CFAE or resultant atrial tachyarrhythmia predicts long term procedural success. Further research to determine the best strategy to achieve this outcome is necessary.

‘Another brick in the wall’. On the origins of nationalism in the ‘new’ federal states of Germany
Authors: Belinskii A. V. , Khorol’skaya M. V.
Published: July 2021

A relatively broad support enjoyed by the populist and nationalist parties and movements (AfD, National Democratic Party of Germany, PEGIDA), as well as a higher rate of hate crimes in the eastern part of the Federal Republic of Germany raise a question on the nature of nationalism in this region. The present paper examines the causes of widespread xenophobic and nationalist sentiments in the ‘new’ federal states. To this end, the authors address a wide range of social-political and psychological factors, focusing on the historical roots and causes of the recent rise of nationalism in East Germany. Particularly, the authors show that the right-wing parties took advantage of popular frustration caused by the collapse of the East German economy after the country’s reuniﬁcation and massive unemployment by putting all the blame on migrants. Nevertheless, the causes of growing xenophobia in East Germany were far from being solely economic. For example, the authors underline the role of the politics of memory in the GDR and primarily the approaches of its leaders to the issues of the Nazi past and their attempts to draw on the country’s history to shape a new national identity. However, the failure of the state to provide an unbiased view on the national history, rigid oﬃcial ideology and its alienation from the popular demands have led to the growing nationalism in the GDR. Besides, a number of other aspects is pointed out which have also fostered xenophobic sentiments in this part of the country. Unlike West Germany which started to accept labour migrants from Italy, Turkey and Yugoslavia back in 1950s, the GDR saw few foreigners and contacts between them and local population were limited. As a result, the paper not only helps to create a more detailed image of the East German nationalism but also to identify the underlying causes of the growing popularity of right-wing populist parties and movements in the FRG, most notably, the unﬁnished process of the country’s reuniﬁcation and structural imbalances between the ‘old’ and the ‘new’ federal states.
Newton's Cradle and Quantum Observation
Authors: Bollinger Terry
Published: July 2021

This paper defines quantum observation as conversion of tiny (attojoule or less) packets of energy and momentum into statistically irreversible Boltzmann heat. Under this definition, quantum waves never “collapse” but instead grow so fractally convoluted in one region of space that their entangled properties in remote regions of space become statistically irreversible and persistent over time. The implication is that far from being a rare phenomenon that depends on such hard-to-define phenomena as human awareness, quantum observation via atto-scale creation of Boltzmann heat is the most common of all quantum phenomena and the underlying basis for the very existence of “classical” matter and objects.

Objetivo: Conocer la epidemiología, tratamiento y seguimiento de pacientes con cáncer de próstata en el Nuevo Hospital Civil de Guadalajara “Dr. Juan I. Menchaca”.

Materiales y métodos: Se realizó un estudio observacional, descriptivo y retrospectivo en el que se incluyeron 196 casos de pacientes con cáncer de próstata atendidos entre los años 2015 y 2020 en el Nuevo Hospital Civil de Guadalajara “Dr. Juan I. Menchaca”.

Resultados: De los 196 casos estudiados la edad media de presentación fue de 72.02 años (±8.77), el 53.5% no cuenta con nivel básico de estudios, asimismo el 87.7% no tiene un empleo formal; el índice de masa corporal (IMC) promedio fue de 25.43 kg/m2  (±3.13), siendo el tabaquismo, hipertensión y diabetes mellitus los factores de riesgo más frecuentes; una media de antígeno prostático específico (APE) antes del tratamiento de 17.59 ng/ml. De los casos atendidos, el 31.07% fueron sometidos a cirugía, 55.05% se encuentran con bloqueo hormonal y 1.02% en vigilancia. Solo se presentaron 12 casos (6.12%) de defunción asociados a cáncer de próstata con un abandono en el seguimiento del 37.75% de la población estudiada.

Limitaciones del estudio: Tamaño de muestra, estudio unicéntrico.

Valor: Estudio reciente de epidemiología de cáncer de próstata en Guadalajara, Jalisco.

Conclusiones: El cáncer de próstata en la población analizada muestra un alto grado de marginación sociocultural, así como factores de riesgo asociados que limitan la indicación de tratamientos con intención curativa; estos factores influyen en el seguimiento adecuado de los pacientes.
Reajuste de Sling TOT: ¿vale la pena?
Authors: Malizia-Reynoso Enzo , Olmedo Jose Javier , Racca María Laura , Marcos Quintero Leandro , Dellavedova Tristán , Minuzzi Susana
Published: July 2021

Introducción: Desde su introducción, el sling TOT se instaló rápidamente como una opción segura y efectiva para el tratamiento de la incontinencia de orina de esfuerzo (IOE) femenina. Con el desarrollo del sling TOT reajustable, se adquirió la posibilidad de reacomodarlo si los resultados funcionales no hubieran sido óptimos (persistencia de IOE).

Objetivos: Analizar los resultados globales de nuestra serie de casos en términos de éxito funcional y complicaciones postquirúrgicas; y analizar la relación entre el reajuste de sling y el desarrollo de obstrucción miccional postquirúrgica, erosión de prótesis, dolor pelviano e insatisfacción con astas de prótesis.

Materiales y Métodos: Se realizó un análisis retrospectivo comparativo entre 2006 y 2016 de pacientes sometidas a colocación de sling TOT reajustable y se analizaron como subgrupo aquellas donde se hubiese realizado un reajuste de sling como segundo procedimiento. El análisis incluyó: presencia de reajuste de sling, erosión de malla, complicaciones relacionadas con astas de prótesis, desarrollo de obstrucción miccional postquirgica, y éxito funcional de la cirugía.

Resultados: Fueron seleccionadas 70 pacientes a quienes se les colocó un sling TOT reajustable (curación de IOE 84.3%; obstrucción postquirúrgica 22.8%), a 11 (15.7%) de las cuales se les realizó reajuste de prótesis por resultados funcionales adversos en las cuales la tasa de curación de IOE ascendió a 92.8% y la tasa de obstrucción post reajuste al 28.5%.

Se encontró una asociación significativa entre el reajuste y el desarrollo de dolor pelviano (36% vs 10%, p=0.02) y no existieron diferencias significativas entre los grupos en el desarrollo de obstrucción miccional postquirúrgica (p=0.23), erosión a vagina (p=0.78), erosión a vejiga (p=0.39) e insatisfacción con las astas de la prótesis (p=0.9).

Conclusión: La posibilidad de elevar el éxito funcional de una primera cirugía en pocos minutos, con anestesia local, y sin diferencias significativas en la mayoría de las complicaciones analizadas, permiten colocar este procedimiento como un complemento útil para el tratamiento de la incontinencia de orina de esfuerzo, lo que no es posible con los slings convencionales.

Published: July 2021

Objetivo: El objetivo del presente trabajo es hacer una revisión de los casos reportados por ultrasonido de microlitiasis testicular y hacer una revisión de la literatura.

Diseño: Se realizó una revisión de los ultrasonidos testiculares en los que se reportó microlitiasis testicular en el periodo comprendido del 2011 a 2018 en el Hospital “Dr. Manuel Gea González”, las variables que se analizaron fueron: edad, motivo del estudio, lado afectado y otros hallazgos.

Resultados: Fueron 21 ultrasonidos con microlitiasis testicular con rango de edad de 6 a 24 años con promedio de 16 años. En el 81% afecto a ambos testículos, y en el 29% afecto el lado izquierdo. En el motivo del estudio el dolor testicular se encontró en el 33 % (7 casos), 14 % por tumor testicular (3 casos), torsión testicular 10% (2 casos), otras causas fueron varicocele, absceso y trauma testiculares.

Limitaciones del estudio: Al tratarse de un estudio observacional retrospectivo, las conclusiones obtenidas son relativas.

Originalidad: La microlitiasis tiene una prevalencia informada entre el 2.4% y el 3.8% en niños, se asocia a neoplasias testiculares y puede causar infertilidad. Se considera como posible etiología algunas nanobacterias que inducen las calcificaciones testiculares por lo tanto el estudio de esta patología podría modificar su tratamiento y prevenir su aparición. 

Conclusiones: La microlitiasis testicular es una patología rara y poco conocida que puede estar asociada a cáncer e infertilidad y al parecer su etiología puede ser infecciosa ocasionada por nanobacterias. Es una patología abierta a la investigación.

Published: July 2021

El término cistopatía diabética describe el aumento de la capacidad de la vejiga y los volúmenes residuales postmiccionales en pacientes diabéticos, acompañado de disminución de la sensación y contracción vesical, atribuida a la neuropatía diabética. La cistopatía diabética es principalmente una enfermedad originada por una neuropatía, de origen sensorial y autonómica por las alteraciones que sufre en la fibras nerviosas; en este articulo se revisaran las múltiples teorías acerca de la fisiopatología. Los pacientes cursan con una sintomatología insidiosa y cuando es detectable se encuentra en una fase avanzada, el principal síntoma es la incontinencia urinaria. Su diagnóstico se establece mediante la presentación clínica asociada a sintomatología neurológica y se confirma con estudios de urodinamia. El control estricto y apego al tratamiento de DM2, es la piedra angular para evitar complicaciones a largo plazo, entre ellas la “Cistopatía Diabética”. Si ya esta establecida la enfermedad el tratamiento farmacológico esta indicado, con una amplia gama de fármacos a elegir; si no es candidato a terapia farmacológica o presenta sintomatología severa el manejo es quirúrgico con varias opciones quirúrgicas como la denervación vesical o la miomectomía.

Published: July 2021

While examining the historical backdrop of clinical procedure, we can understand that medical practitioner have/had created and refined instruments for complicated surgeries. Development in clinical progressions is on a standard with that saw in the sickness causing specialists and infections. Since ancient time, clinical practices were performed using obtrusive medical procedures without sedation, which resulted in high mortality and post-surgery complications. This led to the emergence of effective, safe and user friendly medical instruments and procedures with little to moderately death rate. At present obtrusive methodologies are negligibly practiced, but provides less twisted related complexities, fast organ work return, and more limited hospitalizations. The success of these methods has prompted for higher acknowledgment of picture guided surgeries. We present an Internet Of things (IOT) and Artificial Intelligence (AI) based model that includes a computer generated experience based (VR-based) User interface and some benefits and limitations. It can be done by Raspberry pi, android application and also done by Sap cloud system.

Published: July 2021

Heart disease is the major cause of death ratio increase in this decade. Nowadays various people of different age sector undergo the high risk of heart problems and miss their precious life all of a sudden. Early detection of heart disease will save many people’s life well in advance. Heart Diseases are predictable and they can be identified in earlier stage. First basic method to identify heart disease is ElectroCardioGram (ECG) which is the basic recording method of electrical activities of a functioning heart. ECG is the cheapest and painless method to detect the basic heart problems. This paper is an attempt to detect and classify heart beat signals which will serve as the basic step to predict basic and serious issues which may affect the functioning of the heart. The raw ECG signals are extracted and preprocessed to remove unwanted noises which will produce effective results. The preprocessed ECG signals are then are utilized to identify the heart beats which comprise of signals such as P,Q,R,S,T and U. After detecting the heart beats, they are segmented to extract the ECG Features. The temporal and spectral features are extracted from the segmented ECG signals for classification purpose. The extracted feature vectors are utilized to classify the signals. Radial Basis function and Random Forest method are commonly used classification methodologies; hence these two methodologies are applied to classify the ECG Signals into five basic classes. Massachusetts Institute of Technology-Beth Israel Hospital (MIT-BIH) Arrhythmia database and Noise Stress database are used for this implementation and the classes are identified based on the given dataset parameters. Performance metrics such as accuracy, specificity and sensitivity are computed to find out the best classification methodology among the applied two methodologies. This performance analysis provides a clear comparative view of both the existing methodologies and specifies that Radial Basis function well suits for the given segmented ECG signals and the extracted features. Hence this performance evaluation paves way for best classification algorithm selection or extension of the best methodology and it can be further optimized for better classification result. The implementation process has been carried out using Matlab software environment.

Authors: Devi B Sudha , Misbha D.S
Published: July 2021

In recent years, obesity is highly prevalent and is related with increased risk of many diseases. The distribution of abdominal adipose tissue plays a major role to assess central obesity. The basic objective of this study is to develop a novel method for automatic segmentation of visceral adipose tissue(VAT) and subcutaneous adipose tissue(SAT) from abdominal Magnetic resonance imaging(MRI) slices which is implemented in two steps. First, clustering of image is done to classify MR image into adipose tissue and non-adipose tissue. Second, after clustering the image, segmentation is done to separate VAT and SAT by a convolutional deep neural network. Sixty five MR images have been used in this study where deep learning techniquet have been adopted for the segmentation of VAT and SAT. The proposed and the manual measurements produced the Dice scores of 0.97 and 0.96 for SAT and VAT respectively. The experimental results show that the deep learning method produces better segmentation results with high accuracy.

Admin has to verify the uploaded image for their expiry date.NGO manages the stock which helps to maintain a record of the available medicine. Members can also check their previous data of medicine transactions. The donation of unused medicines is not accepted worldwide, although it is legal in some countries. A constant increase in the rate of prescription writing has prompted several charity organizations to collect a growing number of unused medicines. WHO guidelines for drug donations discourage donation of unused medicines, as this may create a number of problems. Detrimental effects of drug donations for use in emergency situations have been reported, as the arrival of unsorted, useless and expired medicines requires management and sorting, which may take up the time of health workers and eventually lead to the appearance of these drugs on the black market. However, cases of regulated donations have been reported in the USA, where several states have adopted laws in order to facilitate the redistribution of unused drugs to indigent and uninsured patients.This project aims to donate medicines which are unused.
