Performance Improvement in Hospital Management using RFID and ZigBee Technologies for Tracking and Monitoring Patients and Assets in Saudi Arabia
No full textAbstract— This paper outlines a developed framework
for presenting and visualising data from RFID and ZigBee
technologies. The data is gathered from sensors that track
and monitor the location and statuses of patients, medical
staff and medical equipment by using visualisation
concepts to assist in creating, transforming and sharing
knowledge to improve hospital management performance
and help and to support decision making in the Saudi
Arabian healthcare sector
TRACKING AND MONITORING PATIENTS AND ASSETS IN SAUDI ARABIA’ HEALTHCARE ENVIRONMENT
No full textThe Saudi healthcare system still faces a number of challenges despite numerous initiatives that have been taken by the Ministry of Health and relevant healthcare authorities. Most of these challenges relate to the underutilisation of electronic health (e-Health) strategies, and the development of a national system for health information. This paper looks into current issues and barriers in Saudi Arabia healthcare environment. The paper descries the collections and analysis of quantifiable data to support tracking and monitoring of patients and assets in Saudi Arabia’s healthcare environment. The paper also compares current practises with a proposed system for an e-Health framework using Radio Frequency
Identification (RFID) and ZigBee technologies. A survey was conducted on respondents from Saudi Arabia to ascertain the need of tracking and monitoring in a hospital environment. The survey results indicated that implementing tracking system will help in tracking patients as they move about the facility, enabling them to be quickly located for scheduled
treatments or procedures
VALIDATION OF A MEDIA SELECTION FRAMEWORK THROUGH PRACTICAL USE
Get PDFAppropriate use of multimedia brings potential education and learning benefits to students. It is widely accepted that people learn better when the full potentials of multimedia are put to correct use, during the design of educational / learning material. In a previous paper by the authors, we presented an initial media selection framework, used for mapping multimedia to educational concepts. In this paper, we present results of experiments carried out using the framework practically for educational design. Specifically, the paper focuses on validating the framework, in essence, assessing the extent to which it improves learning. The validation experiment compared the performance of students that learned from material designed using the framework, with the performance of students that learned from existing learning materials, both sets of material contained similar educational concepts. We also performed reliability tests (assessing whether the framework produces the same media output for the same educational concept) and usability tests (assessing whether users found the framework easy to use). This paper presents and discusses the results of these tests
A FRAMEWORK FOR MAPPING MULTIMEDIA TO EDUCATIONAL CONCEPTS
Get PDFMultimedia provides exciting opportunities to education as it allows educational material to be delivered in a multitude of ways, fine-tuned to enhance the learning experience. By using multimedia in e-learning systems, educational material can be presented in ways that both simplify and enhance learning. Increasingly, educational material developers are taking advantage of multimedia technology to deliver education but use multimedia in a variety of ways that are more based on intuition and personal experience and this often leads to the development of an ineffective learning material. Although there are not many main media prototypes (animation, images, video, text, audio), when examined at sub-prototype level, we find that there are many media types that can be used to present educational information. Given the number of available media sub-prototypes, the choice and mode of delivery of multimedia presents a problem in designing educational material. What media type or combination of types do we use for a given educational concept? What media combinations will improve learning for a particular educational concept? This paper presents a method for the selection of appropriate media for educational material and demonstrates how the method could be effectively used in the design of educational material, suitable for e-learning applications
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
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
