Authors: Sorgatto Karina Panizzi , Silva Vanessa Neumann
Published: February 2019

Plantas de salsa produzem sementes com germinação lenta e irregular, em função, dentre diversos fatores, da temperatura. O objetivo deste trabalho foi verificar o efeito da embebição de sementes de salsa com extrato de Ascophyllum nodosum na germinação e desenvolvimento de plântulas, em situação de estresse térmico por alta temperatura. Realizou-se o experimento em delineamento inteiramente casualizado, com esquema fatorial 2 x 5 (cultivares x doses), com cinco repetições. Os tratamentos consistiram de cultivares de salsa-crespa e salsa-lisa e doses do extrato de A. nodosum: 0, 1, 2, 4 e 8 ml. L água-1. Efetuaram-se curvas de embebição das sementes. O efeito dos tratamentos foi avaliado por meio das variáveis germinação, porcentagem das raízes e da parte aérea de plântulas e massa seca das raízes e da parte aérea de plântulas. Os resultados foram submetidos a análise de variância e regressão. Verificou-se que a embebição de sementes de salsa com A. nodosum propicia menor tempo necessário para a protrusão da raiz, na situação de estresse térmico (30ºC), comparativamente à embebição em água. De forma geral, nas condições desta pesquisa, nenhuma dosagem de A. nodosum proporciona melhoria na germinação e no desenvolvimento de plântulas de salsa em estresse térmico.
Review of Various Tasks Performed in the Preprocessing Phase of a Diabetic Retinopathy Diagnosis System
Authors: Ashraf Muhammad Nadeem , Hussain Muhammad , Habib Zulfiqar
Published: February 2019

Diabetic Retinopathy (DR) is a major cause of blindness in diabetic patients. The
increasing population of diabetic patients and difficulty to diagnose it at an early stage are limiting
the screening capabilities of manual diagnosis by ophthalmologists. Color fundus images are
widely used to detect DR lesions due to their comfortable, cost-effective and non-invasive acquisition
procedure. Computer Aided Diagnosis (CAD) of DR based on these images can assist ophthalmologists
and help in saving many sight years of diabetic patients. In a CAD system, preprocessing
is a crucial phase, which significantly affects its performance. Commonly used preprocessing
operations are the enhancement of poor contrast, balancing the illumination imbalance due to
the spherical shape of a retina, noise reduction, image resizing to support multi-resolution, color
normalization, extraction of a field of view (FOV), etc. Also, the presence of blood vessels and optic
discs makes the lesion detection more challenging because these two artifacts exhibit specific
attributes, which are similar to those of DR lesions. Preprocessing operations can be broadly
divided into three categories: 1) fixing the native defects, 2) segmentation of blood vessels, and 3)
localization and segmentation of optic discs. This paper presents a review of the state-of-the-art
preprocessing techniques related to three categories of operations, highlighting their significant aspects
and limitations. The survey is concluded with the most effective preprocessing methods,
which have been shown to improve the accuracy and efficiency of the CAD systems.

Nickel Foam Surface Defect Identification Based on Improved Probability Extreme Learning Machine
Authors: Cao Binfang , Li Jianqi , Nie Fangyan
Published: February 2019

Background:

In the nickel foam production process, the detection and identification of
surface defects relies heavily upon the operators’ experiences. However, the manual observation is
of high labor intensity, low efficiency, strong subjectivity and high error rate.

Objective:

Therefore, this paper proposes a new method for the nickel foam surface defect detection
and identification, based on an improved probability extreme learning machine.

Methods:

At first, a machine vision system for nickel foam is established, and gray level cooccurrence
matrix is used to calculate defect features, which are inputted into extreme learning machine
to train the defect classifier. Then a composite differential evolution algorithm is used to optimize
the input weights and hidden layer thresholds. Finally, an integrated probabilistic ELM is
proposed to avoid misjudgments when multiple probabilities values are almost identical.

Conclusion:

Experiments show that the proposed method can achieve a defect-identifying accuracy,
which meets an enterprise’s needs.

Квадрупольное излучение незаряженной капли, осциллирующей в однородном электростатическом поле
Authors: Григорьев А.И. , Ширяева С.О. , Колбнева Н.Ю.
Published: February 2019

AbstractCapillary oscillations of an uncharged spheroid droplet of nonviscous conducting uncompressible liquid in the presence of uniform electric field are analyzed in the first order of smallness with respect to the ratio of the oscillation amplitude to a linear size of the droplet and in the second order of smallness with respect to the squared ratio of the linear size to the radiation wavelength. It is shown that the electric quadrupole moment of the droplet is time-dependent due to surface oscillations, which lead to the emission of quadrupole electromagnetic waves. A mathematical model of the quadrupole electromagnetic radiation of an uncharged droplet that oscillates in the presence of electrostatic field is constructed, and the radiation intensity and frequency are estimated.

Published: February 2019

BACKGROUND

There are up to 19.4 million children who are still unvaccinated and face unnecessary deaths, especially among refugees. However, growing access to smartphones, among refugees, can be a leading factor to improve vaccination rates.

OBJECTIVE

This study aims to determine whether a smartphone app can improve the vaccination uptake among refugees and determine the app’s effectiveness in improving the documentation of vaccination records.

METHODS

We developed and planned to test an app through a cluster randomized trial that will be carried out at the Zaatari refugee camp in Jordan. The study will be open to all parents who carry Android smartphones, have at least one child, and agree to participate in the study. The parents will be recruited to the study by trained volunteers at the vaccination sites around the Zaatari camp. Inclusion criteria will be the following: having at least one child of 0 to 5 years, being a local resident of the camp, and having an Android smartphone.

RESULTS

The intervention includes an app that will allow storing Jordanian vaccination records, per child, on the parents’ smartphones in Arabic and English (in an interchangeable fashion). Every record will have a set of automated reminders before the appointment of each child. The app will summarize immunization records in form of due, taken, or overdue appointments, labeled in orange, green, and red, respectively. Baseline will include the collection of our primary and secondary outcomes that are needed for the pre and postdata measurements. This includes social demographic data, any previous vaccination history, and electronic health literacy. Participants, in both study arms, will be monitored for their follow-up visits to the clinic for vaccination doses. For the study outcome measures, we will measure any differences in the uptake of vaccinations. The secondary outcome is to analyze the effect of the children immunization app on visits for follow-up doses.

CONCLUSIONS

Owing to the limited evidence of effective interventions for childhood vaccination among refugees, research in this area is greatly needed. The project will have a significant impact on the health of refugees and the public health system. In Jordan and the Middle East, the vaccination level is low. Given the influx of refugees from the area, it is crucial to ensure a high vaccination level among the children.

Introduction of Ultrasound Simulation in Medical Education: Exploratory Study (Preprint)
Authors: Hani Selim , Chalouhi Gihad , Lakissian Zavi , Sharara-Chami Rana
Published: February 2019

BACKGROUND

Ultrasound is ubiquitous across all disciplines of medicine; it is one of the most commonly used noninvasive, painless diagnostic tools. However, not many are educated and trained well enough in its use. Ultrasound requires not only theoretical knowledge but also extensive practical experience. The simulated setting offers the safest environment for health care professionals to learn and practice using ultrasound.

OBJECTIVE

This study aimed to (1) assess health care professionals’ need for and enthusiasm toward practicing using ultrasound via simulation and (2) gauge their perception and acceptance of simulation as an integral element of ultrasound education in medical curricula.

METHODS

A day-long intervention was organized at the American University of Beirut Medical Center (AUBMC) to provide a free-of-charge interactive ultrasound simulation workshop—using CAE Vimedix high-fidelity simulator—for health care providers, including physicians, nurses, ultrasound technicians, residents, and medical students. Following the intervention, attendees completed an evaluation, which included 4 demographic questions and 16 close-ended questions based on a Likert scale agree-neutral-disagree. The results presented are based on this evaluation form.

RESULTS

A total of 41 participants attended the workshop (46% [19/41] physicians, 30% [12/41] residents, 19% [8/41] sonographers, and 5% [2/41] medical students), mostly from AUBMC (88%, 36/41), with an average experience of 2.27 (SD 3.45) years and 30 (SD 46) scans per attendee. Moreover, 15 out of 41 (36%) participants were from obstetrics and gynecology, 11 (27%) from internal medicine, 4 (10%) from pediatrics, 4 (10%) from emergency medicine, 2 (5%) from surgery and family medicine, and 5 (12%) were technicians. The majority of participants agreed that ultrasound provided a realistic setting (98%, 40/41) and that it allowed for training and identification of pathologies (88%, 36/41). Furthermore, 100% (41/41) of the participants agreed that it should be part of the curriculum either in medical school or residency, and most of the participants approved it for training (98%, 40/41) and teaching (98%, 40/41).

CONCLUSIONS

All attendees were satisfied with the intervention. There was a positive perception toward the use of simulation for training and teaching medical students and residents in using ultrasound, and there was a definite need and enthusiasm for its integration into curricula. Simulation offers an avenue not only for teaching but also for practicing the ultrasound technology by both medical students and health care providers.
Using Virtual Reality to Improve Antiretroviral Therapy Adherence in the Treatment of HIV: Open-Label Repeated Measure Study (Preprint)
Authors: Liran Omer , Dasher Robert , Kaeochinda Kevin
Published: February 2019

BACKGROUND

Nonadherence to HIV medications is a serious unsolved problem and is a major cause of morbidity and mortality in the HIV-positive population. Although treatment efficacy is high if compliance is greater than 90%, about 40% of people with HIV do not meet this threshold.

OBJECTIVE

This study aimed to test a novel approach to improve medication adherence by using a low-cost virtual reality (VR) experience to educate people with HIV about their illness. We hypothesized that people with HIV would be more likely to be compliant with the treatment following the 7-minute experience and, therefore, should have decreasing viral load (VL), increasing cluster of differentiation 4+ (CD4+) cell counts, and improved self-reported adherence.

METHODS

We showed the VR experience to 107 participants with HIV at a county hospital in Los Angeles, California. Participants were asked to self-report how often they take their medications on a Likert-scale. The self-reported question (SRQ) was given before and at least 2 weeks after the VR experience. We also compared VL and CD4+ cell counts before and on average 101 days after the experience. VL and CD4+ were obtained per the clinic’s standard care protocol. Two-tailed paired t tests were performed on the initial and follow-up SRQ scores, VL, and CD4+. We restricted the CD4+ analysis to participants who had a pre-CD4+ below normal (defined as 500 cells/mm3). To reduce the possibility that VL were trending down and CD4+ were trending up regardless of the VR experience, 2 serial VL and CD4+ obtained before the experience were also compared and analyzed. Immediately following the VR experience, participants were given a 4-question Likert-type postexperience questionnaire (PEQ) that assessed their opinions about the experience.

RESULTS

SRQ scores improved from pre to post experience with high significance (P<.001). VL decreased from pre to post experience by 0.38 log10 copies/mL (95% CI 0.06-0.70; P=.02). In contrast, the 2 serial VL obtained before the experience showed no statistically significant changes. There was also a statistically significant increase in CD4+ (95% CI –3.4 to –54.3 cells/mm3; P=.03). Analysis of the PEQ revealed that VR was comfortable for almost all of the participants and that most participants believed the experience to be educational and that it would improve their medication adherence.

CONCLUSIONS

The findings suggest that the low-cost VR experience caused an increased rate of antiretroviral therapy adherence that resulted in a decrease of VL and an increase of CD4+. Further studies are required to explore the duration of this effect and whether these results are generalizable to other treatment settings and populations.
Monitoring Immobilized Elderly Patients Using a Public Provider Online System for Pressure Ulcer Information and Registration (SIRUPP): Protocol for a Health Care Impact Study (Preprint)
Authors: Vera-Salmerón Eugenio , Rutherford Claudia , Dominguez-Nogueira Carmen , Tudela-Vázquez María Pilar , Costela-Ruiz Victor J , Gómez-Pozo Basilio
Published: February 2019

BACKGROUND

Pressure ulcers represent a major challenge to patient safety in the health care context, presenting high incidence (from 7% to 14% in Spain) and increased financial costs (€400-600 million/year) in medical treatment. Moreover, they are a significant predictor of mortality. The prevention of pressure ulcers in long-term care centers and patients’ own homes is proposed as a priority indicator of health care quality. Early stage risk assessment and database recording are both crucial aspects of prevention, classification, diagnosis, and treatment.

OBJECTIVE

This project proposes a 3-year study of immobilized patients residing in the Granada-Metropolitan Primary Healthcare District (DSGM) and monitored via the Pressure Ulcer Information and Registration System (SIRUPP, Spanish initials). The project aims to estimate the incidence of PUs among immobilized elderly patients, analyze the health-related quality of life of these patients by using the Pressure Ulcer Quality of Life (PU-QoL) instrument in a sample of 250 patients, determine the average time to complete wound healing, estimate the rate of pressure ulcers–associated mortality, and assess the predictive value of the Braden and Mini Nutritional Assessment risk measurement scales in a sample of 1700 patients.

METHODS

The DSGM runs SIRUPP, which is linked to patients’ electronic health records. Currently, 17,104 immobilized patients are monitored under this system. Health-related quality of life will be measured by patient self-reports using the Spanish Pressure Ulcer Quality of Life questionnaire, following cross-cultural adaptation and psychometric validation with respect to the English-language version.

RESULTS

The project commenced in June 2017 and is expected to conclude in April 2020.

CONCLUSIONS

This study addresses two main health outcomes—the time needed for wound healing and the mortality associated with pressure ulcers—both of which might be accounted for by variations in clinical practice and the health-related quality of life of patients with pressure ulcers.

Opportunities and Pitfalls in Applying Emotion Recognition Software for Persons With a Visual Impairment: Simulated Real Life Conversations (Preprint)
Authors: Buimer Hendrik , Schellens Renske , Kostelijk Tjerk , Nemri Abdellatif , Zhao Yan , Van der Geest Thea , Van Wezel Richard
Published: February 2019

BACKGROUND

A large part of the communication cues exchanged between persons is nonverbal. Persons with a visual impairment are often unable to perceive these cues, such as gestures or facial expression of emotions. In a previous study, we have determined that visually impaired persons can increase their ability to recognize facial expressions of emotions from validated pictures and videos by using an emotion recognition system that signals vibrotactile cues associated with one of the six basic emotions.

OBJECTIVE

The aim of this study was to determine whether the previously tested emotion recognition system worked equally well in realistic situations and under controlled laboratory conditions.

METHODS

The emotion recognition system consists of a camera mounted on spectacles, a tablet running facial emotion recognition software, and a waist belt with vibrotactile stimulators to provide haptic feedback representing Ekman’s six universal emotions. A total of 8 visually impaired persons (4 females and 4 males; mean age 46.75 years, age range 28-66 years) participated in two training sessions followed by one experimental session. During the experiment, participants engaged in two 15 minute conversations, in one of which they wore the emotion recognition system. To conclude the study, exit interviews were conducted to assess the experiences of the participants. Due to technical issues with the registration of the emotion recognition software, only 6 participants were included in the video analysis.

RESULTS

We found that participants were quickly able to learn, distinguish, and remember vibrotactile signals associated with the six emotions. A total of 4 participants felt that they were able to use the vibrotactile signals in the conversation. Moreover, 5 out of the 6 participants had no difficulties in keeping the camera focused on the conversation partner. The emotion recognition was very accurate in detecting happiness but performed unsatisfactorily in recognizing the other five universal emotions.

CONCLUSIONS

The system requires some essential improvements in performance and wearability before it is ready to support visually impaired persons in their daily life interactions. Nevertheless, the participants saw potential in the system as an assistive technology, assuming their user requirements can be met.
Using Wearable Physiological Monitors With Suicidal Adolescent Inpatients: Feasibility and Acceptability Study
(Preprint)
Authors: Kleiman Evan , Millner Alexander J , Joyce Victoria W , Nash Carol C , Buonopane Ralph J , Nock Matthew K
Published: February 2019

BACKGROUND

Wearable physiological monitoring devices enable the continuous measurement of human behavior and psychophysiology in the real world. Although such monitors are promising, their availability does not guarantee that participants will continuously wear and interact with them, especially during times of psychological distress.

OBJECTIVE

This study aimed to evaluate the feasibility and acceptability of using a wearable behavioral and physiological monitor, the Empatica E4, to continuously assess a group of suicidal adolescent inpatients.

METHODS

Participants (n=50 adolescent inpatients) were asked to wear an Empatica E4 on their wrist for the duration of their inpatient stay. In addition to assessing behavioral metadata (eg, hours worn per day), we also used qualitative interviews and self-report measures to assess participants’ experience of wearing the monitor.

RESULTS

Results supported the feasibility and acceptability of this approach. Participants wore the monitor for an average of 18 hours a day and reported that despite sometimes finding the monitor uncomfortable, they did not mind wearing it. Many of the participants noted that the part of the study they enjoyed most was contributing to scientific understanding, especially if it could help people similar to them in the future.

CONCLUSIONS

These findings provide promising support for using wearable monitors in clinical samples in future studies, especially if participants are invested in being part of a research study.
Effects of Assistive Robot Behavior on Impressions of Patient Psychological Attributes: Vignette-Based Human-Robot Interaction Study (Preprint)
Authors: Chita-Tegmark Meia , Ackerman Janet M , Scheutz Matthias
Published: February 2019

BACKGROUND

As robots are increasingly designed for health management applications, it is critical to not only consider the effects robots will have on patients but also consider a patient’s wider social network, including the patient’s caregivers and health care providers, among others.

OBJECTIVE

In this paper we investigated how people evaluate robots that provide care and how they form impressions of the patient the robot cares for, based on how the robot represents the patient.

METHODS

We have used a vignette-based study, showing participants hypothetical scenarios describing behaviors of assistive robots (patient-centered or task-centered) and measured their influence on people’s evaluations of the robot itself (emotional intelligence [EI], trustworthiness, and acceptability) as well as people’s perceptions of the patient for whom the robot provides care.

RESULTS

We found that for scenarios describing a robot that acts in a patient-centered manner, the robot will not only be perceived as having higher EI (P=.003) but will also cause people to form more positive impressions of the patient that the robot cares for (P<.001). We replicated and expanded these results to other domains such as dieting, learning, and job training.

CONCLUSIONS

These results imply that robots could be used to enhance human-human relationships in the health care context and beyond.

Published: February 2019

Osteoporosis is a bone disease characterized by reduced bone mass and damage to the microarchitecture of bone tissue. One of osteoporosis types is primary type-1 osteoporosis or postmenopausal osteoporosis due to estrogen deficiency. Calcium is an important mineral that plays a central role in the formation of bone strength structure. Jackfruit seeds (Artocarpus heterophyllus) contain isoflavones that can replace the role of estrogen in the body. Fortification of jackfruit seeds and high calcium milk can be a potential alternative for the treatment of postmenopausal osteoporosis. The purpose of this study was to determine the effect of drinking high calcium milk fortified with jackfruit seed extract (Artocarpus heterophyllus) on alveolar bone collagen fiber density of menopause induced rats. Twenty-five Sprague dawley rats were included in this study. Twenty Sprague dawley rats were ovariectomized, while 5 rats were left untreated (normal control group). Seven days after ovariectomy was performed, 5 rats were treated with fortification of jackfruit seed extract and high calcium milk, 5 rats were treated with jackfruit seed extract, 5 rats were treated with high calcium milk, and 5 rats were left untreated (ovariectomized control group). The treatments were done for 28 days. The rats were euthanized and the alveolar bone was taken and processed for a histological specimen. Alveolar bone collagen fibers were observed under a binocular microscope with 100 magnification. Kruskal-Wallis result showed there was a significant difference in the alveolar bone collagen fiber density among these groups (p<0.05). Mann-Whitney U Test showed a significant difference (p<0.05) in the alveolar bone collagen fiber density of the rats treated with fortification of jackfruit seed extract and high calcium milk compared to the group treated with jackfruit seed extract, that with high calcium milk, or ovariectomized control group. No significant difference in alveolar bone collagen fiber density was found between the group treated with fortification of jackfruit seed extract and high calcium milk and the normal control group (p>0.05). In conclusion, consuming high calcium milk fortified with jackfruit seed extract increases the density of alveolar bone collagen fibers.

Published: February 2019

Los ’60 latinoamericanos estuvieron signados por las iniciativas desarrollistas y por su posterior crítica por parte de los movimientos revolucionarios y las teorías de la dependencia. Acompañando este contexto –y tomando posición clara frente a la contradicción liberación o dependencia– surgió el cristianismo liberacionista. Luego, las dictaduras de los ’70 y los pro-cesos de reconstrucción pos-dictatorial de los ’80 reformularon los términos de la discusión, particularmente en el Cono Sur. Ya no se hablaba de revolución, sino de democracia y de nue-vos movimientos sociales. El cristianismo liberacionista, analizado aquí en las páginas de la revista Alternativa Latinoamericana (1985-1990), tuvo también su palabra y su participación en este nuevo escenario. Sin embargo, tanto en uno como en otro momento, la peculiaridad del pensamiento cristiano tuvo un papel singular en la forma en la cual estos debates fueron plan-teados, determinando el cuestionamiento a los fines culturales de los procesos modernizado-res (y a la Modernidad occidental en general), la protesta contra la colonización de la vida por el capitalismo y la reivindicación del mestizaje.
Jorge Luis Borges, epistemólogo. Una lectura en el espejo (y los laberintos) de las ciencias sociales.
Authors: Retamozo Martìn
Published: February 2019

Este artículo propone reflejar algunos problemas actuales de la epistemología de las ciencias sociales en textos de Jorge Luis Borges. A partir de un conjunto de textos y de figuras propias del universo borgeano, se plantean analogías con problemas ontológicos (la relación de lo infinito con el orden), metodológicos (las maneras de conocer lo plural) y comunicacionales (la capacidad del lenguaje para transmitir el saber).

Programas de transferencia monetaria en la Ciudad de México. El caso de personas mayores y estudiantes
Authors: Czarnecki Lukasz
Published: February 2019

¿Cuál es el efecto de los programas de transferencias monetarias en la Ciudad de México entre jóvenes estudiantes de preparatorias públicas y personas adultas mayores? Para responder esta pregunta de investigación se llevó a cabo una evaluación que comprende estudios cualitativos, basados en encuestas y entrevistas, con 231 estudiantes que cursan el bachillerato público en la Ciudad de México y que son beneficiarias y beneficiarios del Programa PrepaSí, y con 186 personas adultas mayores derechohabientes del Programa de Pensión Alimentaria. A partir del análisis de los resultados sobre dos programas independientes, se concluyó que la evaluación de los programas para ambos grupos de edad muestra falta de coordinación y carencia de satisfacción de las necesidades reales de la gente. Además, las desigualdades persisten aún. Habría que repensar las políticas sociales desde un enfoque de derechos y no desde el punto de vista de la edad, que permita fortalecer la solidaridad intergeneracional en la sociedad, es decir, las buenas prácticas y políticas intergeneracionales que vinculen las acciones del gobierno y de la sociedad civil entre las y los jóvenes y las personas adultas mayores. Esto en el marco de la Convención Interamericana sobre la Protección de Derechos Humanos de las Personas Mayores y la Constitución de la Ciudad de México.

El primero considera la ubicación de la IEE en el comercio internacional por medio del monto de sus exportaciones, lo cual genera un comparativo con las principales industrias. Además, se muestran los cambios en la composición porcentual de los grupos de productos que conforman la IEE. En el segundo capítulo, se seleccionó a los 20 países exportadores más importantes en cada grupo de productos de la IEE de acuerdo con el monto del último año del periodo, 2014. La información se presenta en cuadros que permiten identificar los principales países exportadores y su respectiva tasa de crecimiento anual para cada grupo de productos. El tercer capítulo permite conocer el grado de concentración de mercado de las 20 naciones con mayor participación en cada grupo de productos. De esta manera se observa la dinámica que siguen las exportaciones mundiales para ambas industrias, combinadas y segregadas en grupos de productos. Además, en los cuadros se separan los primeros 5, 10 y 20 principales exportadores, lo que permite observar la evolución en el grado de concentración de mercado para cada grupo de países. En el cuarto capítulo, se presenta el monto de las exportaciones para cada uno de los subsectores que componen a las IEE. Así, es notable la evolución del monto de las exportaciones de cada subsector para cada una de las 20 naciones principales. En el quinto capítulo, se considera el monto de las exportaciones y las importaciones para obtener el saldo de la balanza comercial al desglosar cada subsector de las industrias electrónica y eléctrica para los 20 países principales. Se presentan también los coeficientes de importación y exportación para identificar las características en el comercio exterior de cada industria, subsector y grupo de productos. En el sexto y último capítulo, los datos presentados registran la especialización exportadora de cada nación en la IE por grupo de productos y para cada uno de los 20 países. En los cuadros generados, se puede observar la tasa anual de crecimiento del grupo de productos y su peso en las exportaciones nacionales y mundiales.
