Fluid structure interaction of the non-contact tonometry test
Authors: Ariza-Gracia Miguel Ángel , Wu Wei , Malve Mauro , Calvo Begoña , Rodriguez Matas José Félix
Published: April 2021

The study of corneal biomechanics has gained interest due to its applications on predicting refractive surgery outcomes and the study of a number of pathologies affecting the cornea. In this regard, non-contact tonometry (NCT) has become a popular diagnostic tool in ophthalmology and as an alternative method to characterize corneal biomechanics. Since identification of material parameters using NCT tests rely on the inverse finite element method, accurate and reliable simulations are required. In this work, we present a full fluid structure simulation of a NCT test accounting for the eff ect of the presence of the humors. The results indicate that when inertial effects are considered, not including humors may lead to overestimating corneal displacement, and therefore, to an overestimation of the actual corneal stiffness when using the inverse finite element method.
Automated classification of dry eye type analyzing interference fringe color images of tear film using machine learning techniques
Authors: Yabusaki Katsumi , Arita Reiko , Yamauchi Takanori
Published: April 2021

The unstable balance in secretions of lipids and aqueous fluid to tear film is a significant cause of dry eye disease (DED). Arita et al. demonstrated a simple but very effective method that classifies dry eye types to the aqueous deficient dry eye (ADDE) and the evaporative dry eye (EDE) by focusing on the dry eye type-unique appearances of interference fringe colors and patterns of tear films. We thought this simple classification is very helpful for diagnoses and treatments. However, diagnostic bias by unskilled observers remains an issue to be solved.

The artificial intelligence (AI)-based support for diagnosis is one of the hottest topics in the field of ophthalmology research. We expected that the AI-based model would reduce bias in DED-type diagnoses. Many studies have been reported targeting retinal diseases like age-related macular degeneration and/or diabetic retinopathy. Most of the works established AI-based predicting models using images taken by fundus cameras and/or optical coherence tomography (OCT) devices to capture disease-related structural disorders. In contrast, the interference fringes dynamically change the colors and patterns spatiotemporally. To the best of our knowledge, there is no AI-based model studied for distinguishing ADDE and EDE using interference fringe images. However, an AI-based study classifying the condition of the tear lipid layer by analyzing the textures of interference fringes compared to the device-unique grades has been reported. This suggested the possibility of using the unstructured characteristics, such as colors and/or complexities of interference fringes, as the numerical image features when building AI-based prediction models. In this study, we first examined several types of image characteristics extracted from the colors and patterns of fringes to obtain effective image features for the DED-type classification. We then evaluated whether the AI-based models would have sufficient abilities for this type of prediction by comparing their diagnoses with those made by an ophthalmologist skilled in this classification (the founder of this type classification).

Systemic pathologies such as diabetes and hypertension affect different organs and systems in the body. However, the first signs of these pathologies often emerge as alterations in visual and structural functions in the eye. As a consequence, the ophthalmologist is often the first physician to make a diagnosis of systemic diseases. In fact, the eye represents a unique organ where signs of systemic diseases may be assessed with non-invasive techniques.

Background: The purpose of this research was to investigate the diurnal effect of Ramadan fasting on the amplitude of accommodation and anterior segment parameters in visually healthy participants.Materials and Methods: The study included 68 healthy individuals, aged 26–42 years. The subjective accommodation amplitude was measured using the "minus lens" technique. Corneal refraction (K1, K2, and Kmax), central corneal thickness, corneal volume, anterior chamber volume, and anterior chamber depth parameters were evaluated using the Scheimpflug camera system. Participants were evaluated twice, at 08:00 and 16:00, while fasting during Ramadan. Data were analyzed by paired sample t-test.Results: The mean age of the participants, of which 28 were women and 40 were men, was 34.38±4.93 (range: 26–42). Comparison of measurements taken at 08:00 and 16:00 during fasting showed that at 16:00, the K1 values (08:00: 42.81±1.51 diopter and 16:00: 42.85±1.50 diopter, P = 0.016) and Kmax values (08:00: 44.29 ± 1.73 diopter and 16:00: 44.38±1.78 diopter, P = 0.020) were significantly steeper. When data collected at 08.00 and 16.00 were compared, there were no significant differences in diurnal changes: amplitude of accommodation (08:00: 7.39±1.40 diopter and 16:00: 7.37±1.40 diopter, P = 0.783), central corneal thickness (08:00: 535.60 ± 30.43 µm and 16:00: 535.25±30.66 µm, P = 0.694), corneal volume (08:00: 59.72±3.85 mm3 and 16:00: 59.60±3.98 mm3, P= 0.344), anterior chamber volume (08.00: 170.91±30.77 mm3 and 16.00: 171.22±32.61 mm3, P = 0.808) and anterior chamber depth (08:00: 2.91 ± 0.28 mm and 16:00: 2.92 ± 0.29 mm, P = 0.053).Conclusions: The results showed that dehydration due to fasting affects some anterior segment parameters, such as corneal refraction; however, it does not affect the diurnal changes of amplitude of accommodation, corneal pachymetry, or anterior chamber anatomy.

Imperialismo en el siglo XXI
Authors:   Kingston University, Smith John
Published: April 2021

The globalization of production and its spread to low-income countries is the most notable transformation of the neoliberal era. Its driving force is the efforts by companies in Europe, North America and Japan to cut costs and raise profits, replacing relatively well-paid domestic labor for cheaper foreign labor. The gap in global wages, in great part the result of the suppression of the free movement of labor, provides a distorted view of the global differences in the rate of exploitation (simply, the difference between the value generated by the workers and what they are paid) upon which profits, prosperity and social peace in Europe, North America and Japan are ever-more reliant. Thus, neoliberal globalization should be seen as a new imperialist stage in capitalist development, where «imperialism» is defined by its economic foundation: the exploitation of labor in the South by capitalists from the North.

Desorption of carbon dioxide from monoethanolamine solution via calcium chloride addition under ultrasound irradiation and evaluation of the characteristics of generated calcium carbonate
Authors: Kitamura Yuya , Okawa Hirokazu , Kato Takahiro , Sugawara Katsuyasu
Published: April 2021

We report the desorption of carbon dioxide [CO2(g)] from monoethanolamine (MEA) solution via the addition of calcium chloride (CaCl2) into a CO2-absorbed MEA solution (0.2 M, pH 8.2) under ultrasound treatment (28 kHz, 200 kHz) and stirring (1500 rpm). Ultrasound at 28 kHz had a higher CO2(g) desorption ratio than either ultrasound at 200 kHz or stirring after 1 min [9.2% (28 kHz), 6.2% (stirring), and 5.8% (200 kHz)]. Treatment with ultrasound at 28 kHz resulted in the highest Ca recovery ratio, 89.1%, at 1 min treatment time. The desorption of CO2(g) from the MEA solution using 28 kHz ultrasound started immediately after the initiation of CaCO3 formation. Furthermore, it was found that the average particle size of CaCO3 obtained by ultrasound treatment at 28 kHz and a treatment time of 1 min was 0.91 μm, with a narrow particle size distribution.

Published: April 2021

This letter investigates the large spread of values of capacitance measured in Si/TiO2 MIS structures for different properties of the TiO2 layer and proposes an approach to understand the behavior of the system. Experimental results show large variations of the maximum capacitance with TiO2 thickness for the as-deposited structures and further highlight the change of trend after annealing. Simulations qualitatively depict the theoretical trends explaining the C–V characteristics to the first order, by the different behaviors of the oxide layer in the structure and the distribution of the majority carriers showing depletion effects.
Software Security Requirement Engineering for Risk and Compliance Management
Authors: D. Kavitha , S. Ravikumar
Published: April 2021

The objective of the research work is to propose a software based security requirement engineering model using categorical and morphisms theory. The earlier security requirement engineering models focus different viewpoints on parallel processing and develop rewrite based knowledge centred models but does not include different functional mappings between the security objects to select the best strategy. The security models have not considered the needed security functions that are to be implemented in different environments with different levels of executions. The proposed requirement engineering model is based on the formal theory of category of objects and the morphisms between them in addition to n categories and multiple morphisms that were used to organize the security requirement functional objects of different categories. The on demand security requirement objects, morphisms and the uncertain events in any one of the subsystems are considered to manage this security requirement category as an algebraic data types. The collection of security requirement objects using classification and clustering techniques are implicitly applied by the formation of category and morphism. The risk and compliances both in the form of direct and indirect categories are mapped so as to provide a security assurance functors with minimum risk on the requirements to the next design state. An ‘n’ category and ‘n’ morphic model for software security requirement model is proposed towards for minimum security risks through efficient compliance management techniques.

Image fusion is an important process in the medical image diagnostics methods. Fusing images by obtaining information from different source and different types of images(modals) called multi-modal image fusion. This paper implements an effective and fast spatial domain based multi-modal image fusion using moving frame based decomposition (MFDF)method. Images from two different modalities are taken and decomposed to texture and approximation components. Weight mapping strategy is applied along with the guide filtering to fuse the approximation components using the final map. Weight mapping using the guide filtering is used for the fusing the images from different modalities. MATLAB is used for algorithm implementation. The results obtained are comparatively competitive with the recent publication[11]. Multi modal image fusion thus implemented gives promising results, when compared to moving frame decomposition framework method. The size and the blurring variable of the guiding filter is optimized to obtain a better Structural Similarity Index Measurement (SSIM).

Published: April 2021

A practising doctor in his own surgery has a professional responsibility to earn a regular income for the maintenance of his existence and his employees. Professional risks arise from his activity, which the doctor should regulate with appropriate insurances and powers of attorney. Which of these insurances do doctors have and how important do doctors feel it is to take out such insurances? Are updates made to the insurance policies and what criteria do doctors use to decide for or against insurance? In order to answer this questions, in-depth interviews, mostly face-to-face, were conducted with five doctors of different specialities, professional experience in their own surgery. It was found that doctors contracted insurances that were obligatory, the professional liability and known from their private environment, the legal expenses insurance. Likewise, some insurances were considered unnecessary (i.e. cyber risk) and insurances that sound very similar were confused (i.e. business interruption). The decision-making behaviour for and against insurance was also very different and no clear trend emerged. Due to the rather small sample, further interviews and surveys are necessary to show whether the result is consolidated. It is also advisable to delve deeper into the decision-making behaviour of doctors.

Arduino based Machine Learning and IoT Smart Irrigation System
Authors: Kanade Prakash , Prasad Jai Prakash
Published: April 2021

We all depend on farmers in today's world. But is anybody aware of who the farmers rely on? They don't suffer from various irrigation issues, such as over-irrigation, under irrigation, underwater depletion, floods, etc. We are trying to build a project to solve some of the problems that will help farmers overcome the challenges. Owing to inadequate distribution or lack of control, irrigation happens because of waste water, chemicals, which can contribute to water contamination. Under irrigation, only enough water is provided to the plant, which gives low soil salinity, leading to increased soil salinity with a consequent build-up of toxic salts in areas with high evaporation on the soil surface. This requires either leaching to remove these salts or a drainage system to remove the salts. We have developed a project using IoT (Internet of Things) and ML to solve these irrigation problems (machine learning). The hardware consists of different sensors, such as the temperature sensor, the humidity sensor, the pH sensor, the raspberry pi or Arduino module controlled pressure sensor and the bolt IOT module. Our temperature sensor will predict the area's weather condition, through which farmers will make less use of field water. At a regular interval, our pH sensor can sense the pH of the soil and predict whether or not this soil needs more water. Our main aim is to automatically build an irrigation system and to conserve water for future purposes

undergoing Laparoscopic Cholecystectomy. Participants were divided into two groups in which group P (n=50) received oral pregabalin
150mg with sips of water 1 hour prior to surgery and intravenous normal saline (0.9%) 10ml, 10 mins prior to induction over 10 minutes and
those in group D (n=50) received oral placebo tablet with sips of water 1 hour prior to surgery and intravenous dexmedetomidine at 1mcg/kg
diluted with normal saline (total volume 10ml), 10 minutes prior to induction over 10 minutes. Hemodynamic parameters like heart rate (HR),
systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), oxygen saturation (SPO2) and ETCO2 were
noted before premedication and induction (baseline), at the end of induction and at laryngoscopy and intubation (I0) and then at 1,3,5,10
minutes after intubation as well as atstart of pneumoperitoneum and then after every 10 minutesinterval till the deation of CO2 and also at the

IDIOPATHIC CONDYLAR RESORPTION-A REVIEW
Authors: Sangai Devyani , Banerjee Sujoy , Shenoy Usha
Published: April 2021

Idiopathic condylar resorption (ICR) of the temporomandibular joint (TMJ) is a condition that is often esthetically and functionally altering,
characterized by progressive resorption of the TMJ condylar heads, without a known cause. Studies suggest that patients with ICR remain
undiagnosed and unrecognized in the orthodontic clinic owing to the poorly understood etiology of the disease and lack of diagnostic tools. ICR
often causes occlusal and skeletal changes, TMJ dysfunction and pain, and maxillofacial deformities. Therefore, precise diagnosis of the disease
and proper treatment plan is essential.

Published: April 2021

La formación de una cultura ambiental desde los territorios en los procesos de educación formal implica el desarrollo de prácticas pedagógicas alternativas a las tradicionales enfocadas en la enseñanza de contenidos. En este artículo se exponen los resultados de una indagación documental acerca de experiencias pedagógicas y didácticas, entre los que se destacan variables como: aspectos curriculares, formación docente, problemáticas de la educación ambiental, integraciones curriculares y de comunidades, además el manejo de plásticos de un solo uso. La metodología de análisis de contenido permitió la consulta de revistas especializadas en educación ambiental y en distintas bases de datos. Los hallazgos fueron organizados por categorías, de las cuales el manejo de plásticos de un solo uso en la educación formal fue la principal. Así mismo, se destaca que las actividades realizadas en las instituciones educativas fomentan la reutilización que generan micro plásticos y la incineración libera reacciones químicas como furanos y dioxinas. No existen acciones educativas hacia la disminución en la generación de plásticos.

Authors: Álvarez Gil Yair Rafael
Published: April 2021

El presente artículo hace parte de revisión teórico conceptual de la investigación titulada: “Lineamientos de evaluación socio-formativa por competencias, basado en evidencias, que mejoran las prácticas   evaluativas   de los docentes”, para lo cual se empleó una investigación bibliográfica-documental, en la cual se realizó una de búsqueda, recuperación, análisis crítico e interpretación de datos de fuentes secundarias (Arias, 2012). Posteriormente, se estructuraron las temáticas abordadas en relación al tema central: La evaluación de las competencias matemáticas desde el enfoque socio formativos; desglosándola y describiendo cuatro (4) categorías: las concepciones sobre la evaluación de las competencias matemáticas, las prácticas evaluativas en relación a la evaluación por competencias, la fundamentación teórica del profesorado según el enfoque de evaluación por competencias y lineamiento de evaluación del enfoque socio formativos en a la educación por competencias. Concluyendo que la evaluación de competencias basada en lineamientos socioformativos basados   en   evidencias   en el área de matemáticas, se convierte en una herramienta poderosa para la valoración de los aprendizajes de los estudiantes, evidenciado en las posibles soluciones de situaciones reales en diversos contextos, es decir, evidenciar los desempeños de los educandos en relación a las competencias específicas del área. De igual forma se llega a la comprensión de la articulación entre las concepciones, la fundamentación teórica y las practicas evaluativas en   el área de las matemáticas dentro del enfoque sociformativo, a fin de lograr la coherencia entre lo evaluado y lo aprendido.

Caracterizando el pensamiento variacional desde la resolución de problemas y la teoría fundamentada
Authors: Mariño Luis Fernando , Hernández Rosa Virginia
Published: April 2021

La investigación sirve el propósito de realizar aportes en la caracterización del pensamiento variacional manifestado por un grupo de 24 estudiantes que se forman para ser profesores de matemáticas, cuando resuelven problemas que involucran ecuaciones lineales diofánticas de la forma ax+by = c . El estudio tuvo un enfoque cualitativo con un diseño desde la teoría fundamentada. La estrategia metodológica, estuvo compuesta por un trabajo paralelo entre tres intervenciones que agruparon actividades didácticas como fuentes de datos, los procesos de codificación abierta, axial, selectiva y el análisis de datos permeados siempre por el método de comparación constante, que condujo al muestreo y saturación teórica. Los hallazgos evidencian la forma de pensar variacional de los participantes cuando a partir de sustituciones y combinaciones de números enteros en la ecuación, establecen nexos y relaciones que los llevan a formalizar, generalizar y probar. Como resultado se caracterizó el pensamiento variacional como proceso en la resolución de problemas, conformado por los subprocesos transformar, formalizar, generalizar y probar variacionalmente. Los resultados implican que es posible seguir avanzando en caracterizar el pensamiento variacional desde diversos contextos.y diferentes dominios.

Authors: Alshammari Kaznah , Beach Thomas , Rezgui Yacine
Published: April 2021

Recent technological developments in the construction industry are seeking to create smart cities by using Cyber-Physical Systems (CPSs) to enhance information models such as BIM. Currently, BIM models are commonly adopted to work with IoT-based systems and embrace smart technologies that offer interoperability in the communication layer. In future, it is envisioned that digital twins will provide new possibilities for cyber-physical systems via monitoring and simulation. However, rarely in this rapidly developing field is security fully considered. This paper reviews the relevant literature regarding the use of the IoT in the built environment and analyses current practices. It also presents examples of cities that use the IoT to improve construction and the lived experience. Finally, it reviews how digital twins factor in multiple layers defined in CPSs, from physical objects to information models. Based on this review, recommendations are provided documenting how BIM specifications can be expanded to become IoT compliant, enhancing standards to support cybersecurity, and ensuring digital twin and city standards can be fully integrated in future secure smart cities.
