Design and Implementation of an Embedded Data Acquisition System for Vehicle Vertical Dynamics Analysis.

With the expansion of electronics in recent decades, it is notorious to observe that embedded systems are increasingly necessary to improve people's quality of life and to facilitate the diagnosis of systems in general, ranging from pacemakers to control systems. The increased use of electronic components for technological support, such as telemetry systems, electronic injection, and automotive diagnostic scanners, enhances the perspective of data analysis through an embedded system aimed at vehicular systems. Thus, this work aims to design and implement an embedded data acquisition system for the analysis of vehicle vertical dynamics. The methodology for this study was structured into several stages: mathematical modeling of a motorcycle's mass-spring-damper system, coding for the Arduino microcontroller, computational data analysis supported by MATLAB software version 9.6, electronic prototyping of the embedded system, implementation on the vehicle, and the analysis of motorcycle vertical dynamics parameters. In addition, a mathematical modeling of the mass-spring-damper system was performed using the state-space method. The system was implemented on the Arduino microcontroller platform, enabling real-time data transfer from a motorcycle. The experimental results have successfully validated the proposed data acquisition system.

Objetivo: analizar los efectos de las tecnologías educativas en la prevención y tratamiento de la úlcera diabética. Método: revisión sistemática realizada en siete bases de datos, un índice bibliográfico, una biblioteca electrónica y literatura gris. La muestra estuvo compuesta por 11 ensayos clínicos controlados aleatorizados. La síntesis de los resultados fue descriptiva y mediante metaanálisis. Resultados: las tecnologías educativas predominantes fueron la capacitación y la orientación verbal, se destacaron las tecnologías blandas-duras. En comparación con la atención habitual, las tecnologías educativas demostraron ser un factor protector para prevenir la incidencia de úlcera diabética (RR=0,40; IC 95%=0,18-0,90; p=0,03) y la evaluación de certeza de evidencia fue baja. Las tecnologías educativas también demostraron ser un factor protector para prevenir la incidencia de amputación en miembros inferiores (RR=0,53; IC 95%=0,31-0,90; p=0,02) y la certeza de evidencia fue muy baja. Conclusión: tecnologías educativas blandas-duras, como orientación verbal estructurada, juegos educativos, clase expositiva, capacitación teórico-práctica, video educativo, folder, rotafolio educativo y dibujos lúdicos, y tecnologías duras, como calzado terapéutico, plantillas, termómetro infrarrojo digital, kits para el cuidado de los pies, aplicación de telemedicina y teléfono móvil, resultaron efectivas para la prevención y el tratamiento de la úlcera diabética, sin embargo, es necesario que se realicen estudios más robustos.

Objective: to analyze the effects of educational technologies in the prevention and treatment of diabetic ulcers. Method: a systematic review conducted in seven databases, a bibliographic index, an electronic library and the Gray Literature. The sample consisted of 11 randomized controlled clinical trials. The synthesis of the results was descriptive and through meta-analysis. Results: the predominant educational technologies were training sessions and verbal guidelines, with soft-hard technologies standing out. When compared to usual care, the educational technologies presented a protective factor to prevent the incidence of diabetic ulcers (RR=0.40; 95% CI=0.18-0.90; p=0.03) and the certainty of the evidence assessment was low. The educational technologies also had a protective factor to prevent the incidence of lower limb amputations (RR=0.53; 95% CI=0.31-0.90; p=0.02) and certainty of the evidence was very low. Conclusion: soft-hard educational technologies such as structured verbal guidelines, educational games, lectures, theoretical-practical training sessions, educational videos, folders, serial albums and playful drawings, and hard technologies such as therapeutic footwear, insoles, infrared digital thermometer, foot care kits, Telemedicine app and mobile phone use, were effective for the prevention and treatment of diabetic ulcers, although more robust studies are required.

DeepClassRooms: a deep learning based digital twin framework for on-campus class rooms.

A lot of different methods are being opted for improving the educational standards through monitoring of the classrooms. The developed world uses Smart classrooms to enhance faculty efficiency based on accumulated learning outcomes and interests. Smart classroom boards, audio-visual aids, and multimedia are directly related to the Smart classroom environment. Along with these facilities, more effort is required to monitor and analyze students' outcomes, teachers' performance, attendance records, and contents delivery in on-campus classrooms. One can achieve more improvement in quality teaching and learning outcomes by developing digital twins in on-campus classrooms. In this article, we have proposed DeepClass-Rooms, a digital twin framework for attendance and course contents monitoring for the public sector schools of Punjab, Pakistan. DeepClassRooms is cost-effective and requires RFID readers and high-edge computing devices at the Fog layer for attendance monitoring and content matching, using convolution neural network for on-campus and online classes.

Primer caso de escisión mesorrectal total transanal (TaTME) para el tratamiento del cáncer de recto medio en un centro docente universitario: descripción de la técnica / First case of transanal total mesorectal excision (TaTME) for middle rectal cancer in a teaching tertiary center: technical aspects / Primeiro caso de excisão total do mesorreto transanal (TaTME) para tratamento de câncer de reto meio em um centro universitário de ensino: aspectos tecnicos

La escisión mesorrectal transanal (TaTME: transanal total mesorectal escision) es la última de una larga lista de desarrollos técnicos y tecnológicos para el tratamiento del cáncer de recto medio y bajo. Incluso para los cirujanos colorrectales experimentados, lograr una escisión mesorrectal total (emt) de calidad en cirugía oncológica no siempre es sencillo, por la dificultad de obtener un adecuado acceso a la pelvis. Los estudios realizados han mostrado resultados comparables al abordaje laparoscópico, con tasas elevadas de escisiones mesorrectales completas y bajo porcentaje de margen circunferencial radial (CRM: circumferential radial margin) y distal positivos, con un adecuado número de ganglios resecados. Como toda técnica nueva, su implementación puede traer consecuencias no intencionales. La complejidad del abordaje, la dificultad en la identificación de nuevos repères y planos anatómicos, ha llevado a complicaciones graves como la lesión uretral o la siembra tumoral pelviana. Por ello, la comunidad quirúrgica ha retrasado la implementación masiva de la técnica y desarrollado estrategias de enseñanza y monitorización de este procedimiento para su realización en centros de alto volumen. El objetivo de esta publicación es presentar el primer caso de TaTME en un centro docente universitario y difundir en nuestra comunidad científica el fundamento de la técnica, sus indicaciones, describir los principales pasos técnicos, complicaciones, resultados oncológicos y funcionales.

Transanal total mesorectal excision (TaTME) is the last of a long list of technical and technological developments for treatment of middle and low rectal cancer. Even for skilled colorectal surgeons, achieving a good quality total mesorectal excision (TME) in oncology surgery is not always simple, due to the difficulty of obtaining optimal access to the pelvis. So far, studies have shown similar results to laparoscopic surgery, with high rates of complete mesorectal excisions and low rate of circumferential radial margin (CRM) and distal margin with an appropriate number of resected lymph nodes. Like every new technique, its implementation can bring unwanted consequences. The complexity of the approach, the difficulty in the identification of new landmarks and anatomic planes, has led to serious complications such as urethral injury or tumoral seeding. This has made slowdown the massive implementation of the technique among the surgical community, addressing the need of developing training programs and mentoring of this procedure that belongs to high volume centers. The aim of this publication is to present the first case of TaTME in a teaching tertiary center and spread, in our scientific community, the principles of the technique, its indications, main technical steps, complications and functional and oncologic results.

A excisão mesorretal transanal (TaTME: transanal total mesorectal escision) é o mais recente de uma longa linha de desenvolvimentos técnicos e tecnológicos para o tratamento do câncer retal inferior e médio. Mesmo para cirurgiões colorretais experientes, nem sempre é fácil obter uma excisão total do mesorreto (EMT) de qualidade em cirurgia de câncer, devido à dificuldade de obter acesso adequado à pelve. Os estudos realizados mostraram resultados comparáveis ​​à abordagem laparoscópica, com altas taxas de excisões completas do mesorreto e baixo percentual de margem radial circunferencial positiva (CRM: circumferential radial margin) e distal, com número adequado de linfonodos ressecados. Como qualquer nova técnica, sua implementação pode ter consequências não intencionais. A complexidade da abordagem, a dificuldade em identificar novos repères e planos anatômicos, levou a complicações graves, como lesão uretral ou semeadura de tumor pélvico. Por esse motivo, a comunidade cirúrgica atrasou a implementação massiva da técnica e desenvolveu estratégias de ensino e acompanhamento desse procedimento para sua realização em centros de alto volume. O objetivo desta publicação é apresentar o primeiro caso de TaTME em um centro de ensino universitário e divulgar em nossa comunidade científica as bases da técnica, suas indicações, descrever as principais etapas técnicas, complicações, resultados oncológicos e funcionais.

Colangiografía: duplicación vesicular verdadera / Cholangiography: true gallbladder duplication / Colangiografia: duplicação verdadeira da vesícula biliar

Se presenta una variante anatómica de la vía biliar extrahepática, como lo es la verdadera duplicación vesicular. Las malformaciones congénitas vesiculares se categorizan en anormalidades posicionales y morfológicas, la duplicación vesicular está incluida en este último. La clasificación aceptada es la de Boyden. Basado en la relación del conducto cístico con el cuerpo vesicular describió la "vesica fellea divisa" (vesícula bilobulada que drena a un solo conducto cístico y comparte origen embriológico común) y "vesica fellea duplex" (verdadera duplicación vesicular, dos vesículas separadas con conductos císticos independientes, origen embriológico doble).

La linfadenectomía D3 implica la resección de los ganglios centrales, por delante del eje mesentérico superior. Complementariamente, la escisión mesocolónica completa ha demostrado mejorar los resultados oncológicos.

Development of a Real-Time Surface Solar Radiation Measurement System Based on the Internet of Things (IoT).

The determination of the levels of solar radiation incident on the terrestrial surface (W·m-2) is essential for several areas such as architecture, agriculture, health, power generation, telecommunications, and climate forecasting models. The high cost of acquiring and maintaining radiometric equipment makes it difficult to create and expand monitoring networks. It contributes to the limited Brazilian radiometric network and affects the understanding and availability of this variable. This paper presents the development of a new surface solar radiation measurement system based on silicon photodiodes (Si) with a spectral range between 300 nm and 1400 nm incorporating Internet of Things (IoT) technology with an estimated cost of USD 200. The proposed system can provide instantaneous surface solar radiation levels, connectivity to wireless networks and an exclusive web system for monitoring data. For the sake of comparison, the results were compared with those provided by a government meteorology station (INMet). The prototype validation resulted in determination coefficients (R2) greater than 0.95 while the statistical analysis referred to the results and uncertainties for the range of ±500 kJ·m-2, less than 4.0% for the developed prototypes. The proposed system operates similarly to pyranometers based on thermopiles providing reliable readings, a low acquisition and maintenance cost, autonomous operation, and applicability in the most varied climatological and energy research types. The developed system is pending a patent at the National Institute of Industrial Property under registration BR1020200199846.

Big Data Skills Sustainable Development in Healthcare and Pharmaceuticals.

Big Data technology is one of the most promising organizational processes within the Healthcare and Pharmaceutical industry and crucial for any company that wants to preserve the competitive advantage in the market, where most of the organizational structures are already struggling with the right skills and knowledge to fully support existing business needs for storing and processing and even analyzing information. This paper aims to examine the extent to which new Big Data technology and data-related processes are developing different professionals skills and competencies within the Healthcare and Pharmaceutical industries, and creating sustainable development in addressing critical organizational challenges in recruiting, retaining, and discover professional skills that can fully support the advances and exponential growth of Big Data technology benefits. This research paper also highlights the significant aspects of Big Data in professional technical and process oriented skills development, and the influence it has on organizational business processes including how various internal functions will need to adapt to new circumstances with renewed competency and skills development programs for departments that are strongly connected to the business and analytical needs. We conducted a focus group with twenty-five industry based professionals' ranges from analysts to executive directors to better assess the necessary knowledge to answer the proposed research questions: (1) which professional skills can big data influence in employee development and (2) how can organizations adapt their employee skills to big data. Regarding the key research limitations/implications most of the article and research was built on the foundation of the literature review and the performed focus group. The conceptual recommendations and observations presented provide solid empirical evidence but should be subjected to more comprehensive, large-scale empirical testing and validation. It's recommended for future research a more extensive sample of companies, organizations, and interviewees. Studying a broader set of similar research questions in more homogeneous organizations could provide deeper insights into the process, governance, and stakeholder dimensions of Big Data within specific contexts. Therefore this study contributes to explore in-depth and systematically to what extent Big Data technology and processes are currently influencing the healthcare and pharmaceuticals industries where to the best of the authors' knowledge, it is the first focus group dealing with the presented research questions.

Development and Validation of an Autonomous System for Measurement of Sunshine Duration.

This paper presented an autonomous electronic system for sunshine duration (SD) monitoring based on the contrast method and developed to operate on a horizontal surface. The prototype uses four photoresistors arranged at 90° in a 20 mm diameter circumference separated by a shading structure used to create a shadow pattern on the detection element. Photoresistors are inserted in individual signal conditioning circuits based on the association between Wheatstone bridges and operational amplifiers to provide an analog signal to the microcontroller unit. The determination of SD occurs through the implementation of fuzzy logic with numerical calculation methods to estimate the probability (f) of solar disk obstruction and estimate SD values. The system does not require additional adjustments after installation or use of energy sources for operation due to the use of an internal battery with charge recovery by solar panels. Experimental results of the proposed system were validated with the ones provided by a government meteorology station. Statistical analysis of the results showed a confidence index (c) greater than 90%, with a precision of 94.26%. The proposed system is a feasible low-cost solution to the available commercial systems for the measurement of sunshine duration.

VLC, OCC, IR and LiFi Reliable Optical Wireless Technologies to be Embedded in Medical Facilities and Medical Devices.

New, emerging technologies, transform every day our life and have direct consequence on our health and well-being. More and more wearable medical devices (MD) with wireless communication technologies embedded are being developed by innovative academic community and companies. Optical wireless communication (OWC) consisting of Visible Light Communication (VLC), infrared (IR), Optical Camera Communication (OCC) and Light Fidelity (LiFi) along with the conventional Radio Frequency (RF) wireless communication are suitable technologies to be used for hybrid Wireless Integrated Medical Assistance Systems (WIMAS). The WIMAS addressed in this paper consists of two Wireless Medical Body Area Networks (WMBAN) (an insulin wearable kit and an ECG test device with VLC/OCC are considered) and an Emergency Remote Medical Assistance (ERMA) with LiFi technology embedded. Using RF in medical facilities is subject of strict regulations due to interferences with other RF medical devices, negative effects on human health and lack of security. VLC and OCC are suitable to be embedded in MDs in order to be used by the patients with wearable WMBAN. Research on IR transdermal communication for implantable MDs has also been demonstrated as feasible and both VLC and OCC have promising future, as well. On the other hand, LiFi technology, recently deployed on the market, is mature enough to be integrated in the ERMA system addressed here.

Exploratory Study of Psychosocial Therapies with Text Messages to Mobile Phones in Groups of Vulnerable Immigrant Women.

Various experimental studies on psychosocial therapy have been carried out through text messages with groups of people suffering from depression, anxiety, alcoholism, addictions, etc., but without distinguishing between men and women or highly vulnerable groups such as immigrants. We present an exploratory study of a mobile communication system which intends to improve the mental, physical and social health of a group of vulnerable immigrant women in Spain (n = 71), distinguishing between an intervention group and a non-equivalent control group. We sent automatic text messages (SMS) to the mobile phones of an intervention group formed by immigrant women who used the social services (n = 44). During a 26-day intervention period, the women received 4 daily automatic text messages on their phones, at a predetermined time. We measured mood and depression symptoms at the beginning and end of the intervention, and analysed the qualitative data to determine the acceptance level of a remote message program. The mood and depression symptoms were measured with the personal health questionnaire-9 (PHQ-9) and were significantly better in the intervention group; they evolved from an initial 9.4 (DS = 6.4, range 1-25) to a 5.0 score at the end of the message period (DS = 4.8); with a significant difference (t (44) = 2.01, p = 7.80). Most women stated that the messages had improved their mood (86.3%), which made them feel more connected to their social environment (65.9%) and that they would like to continue receiving more messages (86.6%).

The Impact of Perioperative Data Science in Hospital Knowledge Management.

Conservative practices, such as manual registry have limited scope regarding preoperative, intraoperative and postoperative decision making, knowledge discovery, analytical techniques and knowledge integration into patient care. To maximize quality and value, perioperative care is changing through new technological developments. In this context, knowledge management practices will enable future transformation and enhancements in healthcare services. By performing a data science and knowledge management research in the perioperative department at Hospital Dr. Nélio Mendonça between 2013 and 2015, this paper describes its principal results. This study showed perioperative decision-making improvement by integrating data science tools on the perioperative electronic system (PES). Before the PES implementation only 1,2% of the nurses registered the preoperative visit and after 87,6% registered it. Regarding the patient features it was possible to assess anxiety and pain levels. A future conceptual model for perioperative decision support systems grounded on data science should be considered as a knowledge management tool.

Maturity Assessment Methodology for HISMM - Hospital Information System Maturity Model.

Maturity models have been adopted in organizations from different sectors of activity, as guides and references for information system (IS) management. In the healthcare field, maturity models have also been used to deal with the enormous complexity and demands of hospital information systems (HIS). This article presents a research project that aimed to develop a new comprehensive model of maturity for a health area. HISMM (hospital information system maturity model) was developed to address the complexity of HIS and intends to offer a useful tool to meet the demands of its management. The HISMM has the peculiarity of combining a set of key maturity influence factors and their respective characteristics, enabling not only the assessment of the global maturity of an HIS but also of the individual maturities of its various dimensions. In this article, we present a methodology for the application and implementation of this model in HIS, thus contributing to its widespread practical application and acceptance.

Maturity of hospital information systems: Most important influencing factors.

Maturity models facilitate organizational management, including information systems management, with hospital organizations no exception. This article puts forth a study carried out with a group of experts in the field of hospital information systems management with a view to identifying the main influencing factors to be included in an encompassing maturity model for hospital information systems management. This study is based on the results of a literature review, which identified maturity models in the health field and relevant influencing factors. The development of this model is justified to the extent that the available maturity models for the hospital information systems management field reveal multiple limitations, including lack of detail, absence of tools to determine their maturity and lack of characterization for stages of maturity structured by different influencing factors.

Design and acceptability of a psychosocial text messaging intervention for victims of gender-based violence.

Mobile phones can produce detailed and personalized data to help diagnose, treat, prevent or rehabilitate women who are victims of gender violence. We sent automatic text messages, based on cognitive-behavioural therapy, to female victims of gender violence to assess the feasibility of the medium for mental health intervention. During the 28-day intervention period, each woman received four automatic text messages every day on a pre-established schedule. We evaluated symptoms of depression using the Personal Health Questionnaire-9. The Personal Health Questionnaire-9 decreased from an average of 14.8 at the beginning of the intervention, to 6.1 at the end of the text messaging period. All of the women reported that they liked receiving the messages, they found them useful and they felt that the messages had improved their health. Text messages are acceptable to women users who are recipients of public health and social services. Future research should focus more on the evaluation of the results and on how the specific content and aspects of text messaging improve health outcomes.

Healthcare Workers: Occupational Health Promotion and Patient Safety.

The purpose of the present study was to explore the relation of work-related risk factors and well-being among healthcare workers and the impact on patient safety, using the Health and Work Survey (INSAT) and Mental Health Continuum - Short Form (MHC-SF). A sample of 361 Portuguese healthcare workers participated in this study. The results indicate some significant work-related risk factors: for emotional well-being, Impossible to express myself (ß = -0.977), Not having recognition by superiors (ß = -1.028) and Have to simulate good mood and/or empathy (ß = -1.007); for social well-being, Exposed to the risk of sexual discrimination (ß = -2.088), Career progress is almost impossible (ß = -1.518), and Have to hide my emotions (ß = -2.307); finally for psychological well-being Exposed to the risk of sexual discrimination (ß = -2.153), Career progress is almost impossible (ß = -1.377), and Have to simulate good mood and/or empathy (ß = -3.201). The results showed high levels of well-being despite the exposure of several risk factors at workplace. Regarding the work-related risk factors, the study showed that most of the participants are exposed to several risk factors at workplace (ranging from environmental risk factors, biological to physical), although psychosocial risk factors (work relations with superiors and colleagues, employment relations, and emotional demands) are the ones that most impact on well-being.

How Can Geography and Mobile Phones Contribute to Psychotherapy?

Interdisciplinary relationships between Geography and Psychotherapy are an opportunity for innovation. Indeed, scientific works found on bibliographic databases and concerning this theme are scarce. Geographical sub-fields, such as the Geography of Emotions or Psychoanalytical Geography have started to emerge, theorizing about and interpreting feelings, emotions, moods, sufferings, of the chronically ill or diversified social groups and sites. But a less theoretical and more practical approach, in the sense of proposing, predicting and intervening, is lacking; as well as research into the possibilities offered by communication technologies and mobile phones. In the present work, we present the results of a review of the most relevant scientific works published internationally; we reflect on the contributions of Geography and mobile phones to psychosocial therapies and define the orientation and questions that should be posed in future research, from the point of view of geography and regarding psychotherapy. We conclude that the production of georeferenced data via mobile phones concerning the daily lives of people opens great possibilities for cognitive behavioural therapy and mental health. They allow for the development of personalized mood maps that locate the places where a person experiences greater or lesser stress on a daily basis; they allow for a cartography of emotions, a cognitive cartography of the places we access physically or through the Internet, of our feelings and psychosocial experiences. They open the door to the possibility of offering personalized psychotherapy treatments focusing on the ecological-environmental analysis of the places frequented by the person on a daily basis.

Development and Validation of a Health and Work Survey Based on the Rasch Model among Portuguese Workers.

The purpose of this study was to develop the Health and Work Survey (INSAT) and examine the validity of the discomfort rating scale. Data were collected from 706 Portuguese workers from six economic sectors with the support of the Health and Work Survey (INSAT - Inquérito Saúde e Trabalho). The INSAT is a self-administered questionnaire to assessing working conditions, health and wellbeing, and to provide information to the occupational health systems in the organisations. For the survey instrument validation, the Rasch Partial Credit Model (PCM) was used to analyse item fit statistics. From the application of PCM, Person Separation Reliability was obtained (0.8761) and the value can be considered very good (>0.8). From the statistical analysis, the Overall Model fit information, given by Outfit Mean square/Infit Mean square, is between 0.5 and 1.5, meaning "Productive for measurement" and "acceptable fit overall". The INSAT items can generate predictable response patterns. We recommend that the INSAT discomfort rating scale and some other items should be reviewed in future works. In any event, this tool proves to be useful in assessing the relationship between work and health and in evaluating key main risk factors, helping to prevent problems and improving occupational health systems.
