Framework for an Integrated Ehealth Platform with Smart Diagnostic Engine for Improved Healthcare Access for Rural Dwellers
Get PDFThe healthcare challenges faced by rural dwellers in developing nations, especially
those in the African continent include a lack of sufficient workforce, especially doctors,
lack of healthcare facilities and access to the required medications. This paper presents
a framework for the development of an integrated Ehealth platform which will provide
the rural dwellers with access to high-quality medical personnel located in the urban
areas. The unique advantages of this platform range from the inclusion of reputable
pharmacies and medical diagnostic labs to minimize the risk of fake drugs and wrong
diagnostic results coupled with integrated drug delivery and sample collection system
which can be implemented using taxis, motorbikes or drones. The system also
incorporates an Artificial Intelligence-based disease diagnostic engine which is
designed to learn continuously from the patient/doctor interactions and support the
doctor in the patient diagnosis. This system presents a robust solution for providing
rural dwellers with access to qualified medical service and also enable the doctors to
prescribe high-quality drugs from reputable pharmacies close to the patient for the
patient’s use. Governments and donor agencies can utilize this platform to provide and
pay for quality medical service to rural areas while at the same time, being able to track
the spread of diseases
Robust E-Health Communication Architecture for Rural Communities in Developing Countries
Get PDFThe lack of access to quality healthcare and the lack of
sufficient manpower, especially doctors, in rural areas is a major
healthcare challenge faced by dwellers in rural communities in
most developing countries. The intervention of governments,
which range from the introduction of training programs aimed at
producing health workers from schools of health technology and
nursing to the recalling and deployment of retired nurses to rural
areas, has still not been able to generate the desired improvement
in healthcare delivery, as outbreaks of epidemics are still being
reported in such areas. This work presents an E-Health
architecture which utilizes low cost sensors and communication
devices to link the doctors in the urban areas with the patients in
rural areas enabling doctors-patients interaction. The system
enables accurate and timely diagnosis of the patients and
facilitates proper treatment plans. It also incorporates an
epidemic alert which enables the tracking of diseases and the
early detection and control of epidemics
Development of an Automated, Real-Time Health Monitor and Emergency Alert System for the Elderly
Get PDFThe state of health of the elderly members of society and the fact that most of this group of persons either live alone or with family creates a need for constant monitoring as they are often times left alone for the greater part of the day when their hosts or family members have to go to work. The most common cause of death among the aged is heart related. Heath related medical emergencies range from heart attacks to strokes which happen suddenly leaving the victims with little or no ability to call for help. This system provides a means of monitoring the heart rate, temperature and blood pressure of the individual. It also has the capability of sending a pre stored message to the control center which passes it on to the nearest medical team or emergency response team indicating the location of the user, the vital signs and some medical history in the event of an emergency when the alert function is activated. These messages are sent using the GSM-SMS technology and are delivered within seconds of activation. The system can be provided by the health care providers, emergency response service providers, HMO and hospitals. The device is to be worn all times by the individuals such that they are monitored in real time. The system also has a panic button which can be activated by the user for medical challenges other than heart related cases where the individual is not able to reach a phone. The system also incorporates a GPS receiver system capable of transmitting the location of the user in the event that the emergency occurred outdoors. The system provides a real time monitoring of the health conditions of the aged and enables a faster deployment of paramedics in the event of a medical emergency
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Design of a Real-Time Epidemic Alert System for Cross Border Disease Control and Epidemic Management
Get PDFThe key challenge with Epidemics includes its ability to spread rapidly and impact several large communities with high fatality rates. These characteristics make it difficult and very expensive to manage epidemics once it has broken out. History is replete with several cases of epidemic out breaks spreading from the point of origin and being transmitted to other areas resulting in the deaths of several thousands and in some cases millions of the inhabitants. The distance of the spread in the early 19th century was limited due to the limitations in travel speed and distance but this did not reduce the death rates of these diseases. The small pox disease was recorded to have killed more than 20% of the population of Athens in Greece. The great plague of London was recorded to have started in China in 1334 but spread along the trade routes wiping out entire towns. Florence in Italy lost a third of its entire 90,000 residents in the first six months with Europe losing an estimated 25 Million people. In 1633, Massachusetts which hitherto had been free from small po
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
