Studies have indicated that up to 13% of the deaths of children under the age of five could be prevented by breastfeeding alone. One key barrier is the availability of breast milk for vulnerable infants (those born pre-term, with low birth-weight, to HIV-positive mothers, or orphaned at birth). One strategy to increase availability of breast milk is establishing human milk banks that process donor milk. However, it has been difficult to provide safe, pasteurized donor breast milk to infants in developing countries due to cost and lack of infrastructure. Low-cost pasteurization methods require rigorous temperature monitoring and quality assurance processes for adoption at scale.\u0000 In this paper, we present an affordable system to monitor breast milk pasteurization. It leverages mobile and sensing technologies to enhance an existing, low-cost pasteurization method called flash heat pasteurization. A mobile application, running on an Android phone that is connected to a temperature probe, monitors milk temperatures during pasteurization, and provides audiovisual feedback to guide users performing the procedure. At the end of the procedure, users are able to print a pasteurization report, and labels for pasteurized milk jars from the mobile application. The pasteurization temperature curve is also uploaded to a server that enables supervisors to remotely review procedures and perform audits to ensure that procedures are being performed correctly.\u0000 We discuss the lessons learned from ongoing deployments at two locations in Durban, South Africa. To date they have processed microbial assays for 40 donor milk samples in which 31 samples showed microbial activity pre-pasteurization, while none of the post-pasteurized samples show any microbial growth. We are currently working with the Human Milk Banking Association of South Africa to scale up the use of the system to more sites.","PeriodicalId":240004,"journal":{"name":"ACM DEV '13","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128623583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Better real-time information about congestion levels can help with more effective use of infrastructure, for example allowing journey planning based on predicted congestion levels, or on selecting optimal routes based on current congestion levels at different places. In this paper we describe hardware and image processing methods for constructing a vision-based traffic congestion monitoring system tailored to the constraints of monitoring chaotic developing world traffic. By designing roadside monitoring units around camera phones, our prototype radically reduces costs compared to convential CCTV systems and hence makes it practical for deployment in this context. We show results from this system operating in Kampala.","PeriodicalId":240004,"journal":{"name":"ACM DEV '13","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124884376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our design is based on literature review and feedback from midwives who have worked in developed and developing countries. From the systematic review of existing literature we developed a list of design requirements. Later on we filtered them by consulting midwives & gynecologists. Based on the refined requirements we developed the concept of a rural diagnostic application to support antenatal care. Furthermore, we identified the technical requirements and limitations that should be taken into account to implement the system in a rural setting. We believe that our initial exploration will help to design a usable system which will play a key role in improving antenatal care in developing countries.","PeriodicalId":240004,"journal":{"name":"ACM DEV '13","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130160036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since most of the operations in a typical mobile phone require a minimum level of literacy, it has become interesting to know how these illiterate people manage to operate these phones. Understanding this usage pattern would help us design an effective user interface for these people. At the same time, it would help us understand the human learning behavior while interacting with a technical artifact. In this short communication, we present the initial findings of our ongoing project on investigating many of the questions related to this issue. Here we try to get an idea of how illiterate people use the memory of mobile phones. We present here our initial findings from our investigation upon 15 illiterate mobile phone users in Bangladesh.

However, the development of appropriate and scalable EHR systems in developing countries has been difficult to achieve because of certain limitations inherent in the technological infrastructure. In this paper, we present a comparative study of 19 EHR systems in terms of the security and usability of these systems within the context of the developing world. Our aim was to investigate whether online health services designed for developed countries can be adopted for EHR systems in developing countries. The investigation was based on a number of dimensions such as development environment, system platform, type and access control standards found in the National Institute for Standard and Technology (NIST) and Certification Commission for Health Information Technology (CCHIT). Our research indicates that all the systems evaluated require online access control decisions. Solely relying on an online access control system is limiting, particularly in developing countries where access to the server can be disrupted by a number of disastrous events.","PeriodicalId":240004,"journal":{"name":"ACM DEV '13","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129221187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we present the development and evaluation of an application specific speech recognizer for Hindi. We use the Salaam method [4] to bootstrap a high quality speech engine in English to develop a mobile speech based agricultural video search for farmers in India. With very little training data for a 79 word vocabulary we are able to achieve >90% accuracies for test and field deployments.
