Title from PDF of title page, viewed on July 9, 2014Thesis advisor: Praveen R. RaoVitaIncludes bibliographical references (pages 32-35)Thesis (M. S.)--Dept. of Computer Science and Electrical Engineering. University of Missouri--Kansas City, 2013Millions of children born worldwide do not receive proper vaccination. Driven by the concern for the lives of such children, institutions and organizations around the world have emphasized the need to strengthen vaccination surveillance and monitoring in developing countries to prevent the spread of vaccine-preventable diseases. In this regard, we present a cell phone based application called Jeev to track the vaccination coverage of children in rural communities. Jeev synergistically combines the power of smartphones and the ubiquity of cellular infrastructure, Quick Response (QR) codes, and national identification cards. In this work we present the design of Jeev and highlight its unique features along with an extended evaluation of its performance. We plan to continue our investigation by pilot testing Jeev in a rural population to study its effectiveness and identify socio-cultural issues that may arise in a large-scale deployment.Introduction -- Background and related work -- Design and architecture -- Preliminary evaluation -- Conclusion and future work -- Appendix: SQL statements

Assessing and augmenting SCADA cyber security: a survey of techniques

SCADA systems monitor and control critical infrastructures of national importance such as power generation and distribution, water supply, transportation networks, and manufacturing facilities. The pervasiveness, miniaturisations and declining costs of internet connectivity have transformed these systems from strictly isolated to highly interconnected networks. The connectivity provides immense benefits such as reliability, scalability and remote connectivity, but at the same time exposes an otherwise isolated and secure system, to global cyber security threats. This inevitable transformation to highly connected systems thus necessitates effective security safeguards to be in place as any compromise or downtime of SCADA systems can have severe economic, safety and security ramifications. One way to ensure vital asset protection is to adopt a viewpoint similar to an attacker to determine weaknesses and loopholes in defences. Such mind sets help to identify and fix potential breaches before their exploitation. This paper surveys tools and techniques to uncover SCADA system vulnerabilities. A comprehensive review of the selected approaches is provided along with their applicability

Designing a Multimedia Intervention for Illiterate and Semi-Illiterate Pregnant Women in Developing Countries: A Case of Uganda

Die hohe Müttersterblichkeit in Entwicklungsländern ist zum Teil auf indirekte Faktoren wie Analphabetismus und eingeschränkten Zugang zu Gesundheitsinformationen für Mütter zurückzuführen. Während gebildete Frauen auf Gesundheitsinformationen über Online-Plattformen und mHealth-Apps zugreifen können, müssen Analphabetinnen diese in Gesundheitseinrichtungen abrufen, was aufgrund der Transportkosten oft nicht möglich ist. Mobilfunktechnologie hat in der Gesundheitsversorgung Chancen für ressourcenarme Gemeinschaften eröffnet, die sonst nicht von den digitalen Technologien profitiert hätten. Obwohl Mobilfunktechnologie in der Müttergesundheit eingesetzt wird, können die meisten Maßnahmen nicht von Analphabeten genutzt werden, verwenden Sicherheitsmodelle die nicht auf den Kontext von Entwicklungsländern zugeschnitten sind, und wurden nicht auf ihre Auswirkungen auf die Müttergesundheit hin evaluiert. In dieser Arbeit wurden zwei (Web und Mobile) Apps entwickelt, die die Übermittlung von multimedialen Nachrichten zur Müttergesundheit, Terminerinnerungen und Anrufe/Chats erleichtern. Um die Anforderungen der Nutzer zu erfassen, wurde eine Feldstudie mit halbstrukturierten Interviews und Fokusgruppendiskussionen mit schwangeren Analphabetinnen, Gesundheitsexperten und Entwicklern durchgeführt. Es folgte die Entwicklung eines Sicherheitsmodells (T2RoL) zur Sicherung der Gesundheitsinformationen in den Apps, die dann nach einem nutzerzentrierten Designansatz entwickelt wurden. Eine zweite Feldstudie in Form von halbstrukturierten Interviews und Umfragen wurde durchgeführt, um die mobile App in einer randomisierten kontrollierten Studie mit 80 schwangeren Analphabetinnen über 9 Monate zu evaluieren. Die Auswertung zeigte, dass die App akzeptiert wurde sowie einfach zu erlernen und zu benutzen war. Das Wissen über Müttergesundheit in der Interventionsgruppe verbesserte sich, was sich positiv auf gesundheitsbezogene Entscheidungen und Gesundheitsmaßnahmen auswirkte.Maternal mortality is high in developing countries partly due to indirect factors such as illiteracy and limited access to maternal health information. While literate women can access health information from online platforms, and mHealth apps, illiterate women must get it from health facilities which is often not possible due to lack of transport fees. Mobile technology has opened opportunities in maternal health care for low resource communities that would otherwise not have benefited from digital technologies. Although used in maternal health, most interventions are not usable by the illiterate, use security models that are not tailored to the developing countries’ context, and have not been evaluated to assess their impact on maternal health care. In this thesis, two (web and mobile) apps that facilitate delivery of multimedia-based maternal health messages, appointment reminders, and calls/ chats were developed. To gather user requirements, a field study in form of semi-structured interviews and focus group discussions was conducted with illiterate pregnant women, health practitioners and developers. Development of a security model (T2RoL) to secure the health information in the apps followed. The apps were then developed following a user-centered design approach. A second field study in form of semi-structured interviews and surveys was conducted to evaluate the mobile app through a randomized controlled trial with 80 illiterate pregnant women that were followed for 9 months. Overall, results show that the app was acceptable, easy to learn and use. There was improved maternal health knowledge among the intervention group which positively influenced health related decision making and health practices

On-Cloud Motherhood Clinic: A Healthcare Management Solution for Rural Communities in Developing Countries

Background: Modern telecommunication infrastructure enables bridging of the digital divide between rural and urban healthcare services, promoting the provision of suitable medical care and support. Thus far, there has been some positive impacts to applying mobile health (m-Health) solutions, but their full potential in relation to cloud computing has is yet to be realised. It is imperative to develop an innovative approach for addressing the digital divide in a context of developing country. Method: Adopting a design science research approach (DSR), this study describes an innovative m-Health solution utilising cloud computing that enables healthcare professionals and women in rural areas to achieve comprehensive maternal healthcare support. We developed the solution framework through iterative prototyping with stakeholders’ participation, and evaluated the design using focus groups. Results: The cloud-based solution was positively evaluated as supporting healthcare professionals and service providers. It was perceived to help provide a virtual presence for evaluating and diagnosing expectant mothers’ critical healthcare data, medical history, and in providing necessary service support in a virtual clinic environment. Conclusions: The new application offers benefits to target stakeholders enabling a new practice-based paradigm applicable in other healthcare management. We demonstrated utilities to address target problems as well as the mechanism propositions for meeting the information exchange demand for better realisation of practical needs of the end users.

Modular wireless networks for infrastructure-challenged environments

While access to Internet and cellular connectivity is easily achieved in densely-populated areas, provisioning of communication services is much more challenging in remote rural areas. At the same time Internet access is of critical importance to residents of such rural communities. People's curiosity and realization of the opportunities provided by Internet and cellular access is the key ingredient to adoption. However, poor network performance can easily impede the process of adoption by discouraging people to access and use connectivity. With this in mind, we evaluate performance and adoption of various connectivity technologies in rural developing regions and identify avenues that need immediate attention to guarantee smoother technology adoption. In light of this analysis we propose novel system designs that meet these needs. In this thesis we focus on cellular and broadband Internet connectivity. Commercial cellular networks are highly centralized, which requires costly backhaul. This, coupled with high price for equipment, maintenance and licensing renders cellular network access commercially-infeasible in rural areas. At the same time rural cellular communications are highly local: 70% of the rural-residential calls have an originator-destination pair within the same antenna. In line with this observation we design a low-cost cellular network architecture dubbed Kwiizya, to provide local voice and text messaging services in a rural community. Where outbound connectivity is available, Kwiizya can provide global services. While commercial networks are becoming more available in rural areas they are often out of financial reach of rural residents. Furthermore, these networks typically provide only basic voice and SMS services and no mobile data. To address these challenges, our proposed work allows Kwiizya to operate in coexistence with commercial cellular networks in order to extend local coverage and provide more advanced services that are not delivered by the commercial networks. Internet connectivity in rural areas is typically provided through slow satellite links. The challenges in performance and adoption of such networks have been previously studied. We add a unique dataset and consequent analysis to this spectrum of work, which captures the upgrade of the gateway connectivity in the rural community of Macha, Zambia from a 256kbps satellite link to a more capable 2Mbps terrestrial link. We show that the improvement in performance and user experience is not necessarily proportional to the bandwidth increase. While this increase improved the network usability, it also opened opportunities for adoption of more demanding services that were previously out of reach. As a result the network performance was severely degraded over the long term. To address these challenges we employ white space communication both for connectivity to more capable remote gateways, as well as for end user connectivity. We develop VillageLink, a distributed method that optimizes channel allocation to maximize throughput and enables both remote gateway access as well as end user coverage. While VillageLink features lightweight channel probing, we also consider external sources of channel availability. We design a novel approach for estimation of channel occupancy called TxMiner, which is capable of extracting transmitter characteristics from raw spectrum measurements. We study the adoption and implications of network connectivity in rural communities. In line with the results of our analyses we design and build system architectures that are geared to meet critical needs in these communities. While the focus of analysis in this thesis is on rural sub-Saharan Africa, the proposed designs and system implementations are more general and can serve in infrastructure-challenged communities across the world

A hybrid model for managing personal health records in South Africa

Doctors can experience difficulty in accessing medical information of new patients. One reason for this is that the management of medical records is mostly institution-centred. The lack of access to medical information may negatively affect patients in several ways. These include new medical tests that may need to be carried out at a cost to the patient and doctors prescribing drugs to which the patient is allergic. This research investigates how patients can play an active role in sharing their personal health records (PHRs) with doctors located in geographically separate areas. In order to achieve the goal of this research, existing literature concerning medical health records and standards was reviewed. A literature review of techniques that can be used to ensure privacy of health information was also undertaken. Interview studies were carried out with three medical practices in Port Elizabeth with the aim of contextualising the findings from the literature study. The Design Science Research methodology was used for this research. A Hybrid Model for Managing Personal Health Records in South Africa is proposed. This model allows patients to view their PHRs on their mobile phones and medical practitioners to manage the patients’ PHRs using a web-based application. The patients’ PHR information is stored both on a cloud server and on mobile devices hence the hybrid nature. Two prototypes were developed as a proof of concept; a mobile application for the patients and a web-based application for the medical practitioners. A field study was carried out with the NMMU health services department and 12 participants over a period of two weeks. The results of the field study were highly positive. The successful evaluation of the prototypes provides empirical evidence that the proposed model brings us closer to the realisation of ubiquitous access to PHRS in South Africa

Use of digital technologies in public health: a narrative review.

BACKGROUND AND AIM Websites, social media networks and mobile applications constitute important communication tools, while simultaneously enabling the population to increase their knowledge of health issues. This study aims to describe digital health experiences in Public Health to examine the different possible uses of digital technologies by Public Health Operators (PHOs) and Health Care Workers (HCWs) and the role these tools play in the efficiency of the health interventions undertaken. METHODS A narrative literature survey was conducted by consulting the PubMed and Scopus databases to find articles relevant to the topic of interest. The selection criteria adopted for manuscript screening involved including the survey studies dealing with the use of digital means such as new media in Public Health, published between 1 January 2012 and 31 May 2021. RESULTS Based on the keywords, 2,019 manuscripts were identified, of which 45 were included. The articles were grouped according to the digital tool (social media network, mobile application and websites) employed by PHOs and/or HCWs in health promotion initiatives. Specifically, this was broken down into: i) the use of social media in public health: 24 articles, ii) the use of mobile applications: 10 articles, iii) the use of websites: 8 articles and iv) the use of the three digital tools combined: 3 articles. CONCLUSIONS The results of this study indicate that digital technologies may play a useful role in Public Health to improve communication between health professionals and patients, provide quality care even remotely and facilitate the achievement of health outcomes for the population from a Health Literacy perspective

Mobile Health Technologies

Mobile Health Technologies, also known as mHealth technologies, have emerged, amongst healthcare providers, as the ultimate Technologies-of-Choice for the 21st century in delivering not only transformative change in healthcare delivery, but also critical health information to different communities of practice in integrated healthcare information systems. mHealth technologies nurture seamless platforms and pragmatic tools for managing pertinent health information across the continuum of different healthcare providers. mHealth technologies commonly utilize mobile medical devices, monitoring and wireless devices, and/or telemedicine in healthcare delivery and health research. Today, mHealth technologies provide opportunities to record and monitor conditions of patients with chronic diseases such as asthma, Chronic Obstructive Pulmonary Diseases (COPD) and diabetes mellitus. The intent of this book is to enlighten readers about the theories and applications of mHealth technologies in the healthcare domain
