Cloud computing is coming of age; it involves on-demand access to a shared pool of configurable computing resources. There is an emerging consensus that cloud computing will play a critical role in redressing the digital divide especially in rural areas of Africa. In this paper, we report on a success story to this end; the use of cloud computing in expanding the access of students' records management system to resource-constrained schools in the Free State province of South Africa. This was motivated by the fact that despite the proven tight correlation between availability of data and quality of education, many schools that are considered part of the `second economy' in South Africa continue to operate in uni-direction data flow arrangements that do not provide them with adequate data for critical decision making. We implemented and evaluated a Cloud based School Administration and Management System; hereby called `Cloud SAMS' for these resource-constrained schools in the province (they account for over 80% of all schools). Starting off with 5 schools and later ramping it up to 50, `Cloud SAMS' enables schools to securely and privately share one copy of the system maintained in the cloud; this brings on board several benefits - low cost, faster implementation and resilience to failures.
云计算正在走向成熟;它涉及按需访问可配置计算资源的共享池。人们正在形成共识,认为云计算将在消除数字鸿沟方面发挥关键作用,特别是在非洲农村地区。在本文中,我们报道了一个成功的故事;利用云计算将学生档案管理系统扩大到南非自由州省资源有限的学校。这样做的动机是,尽管数据的可用性与教育质量之间存在紧密的相关性,但许多被认为是南非“第二经济”一部分的学校继续以单向数据流安排运作,这不能为他们提供足够的关键决策数据。我们实施并评估了基于云的学校行政和管理系统;针对省内资源有限的学校(占全省学校总数的80%以上),特将其称为“云SAMS”。从5所学校开始,后来增加到50所学校,“云SAMS”使学校能够安全地私下共享在云中维护的系统副本;这带来了几个好处——低成本、更快的实施和对失败的弹性。

Information and communication technology is one of the most versatile technologies that have substantially impacted all sectors of today's world. The flexibility and capability of these technologies to be dynamically and seamlessly integrated into diverse problem domains has made them an attractive problem solving tool. However, the adoption of ICT is not without challenges. In rural South Africa in particular, the sustainability of ICT projects, especially in rural schools, remains a potential hurdle. Concerted research efforts have dealt with the subject of sustainability in dimensions that focus more on addressing economic, socio-cultural, and political concerns. But, technical sustainability, which is critical to ICT infrastructure, has been given little or no attention. Considering technical sustainability in ICT models will salvage project failure and avert resource wastage among other benefits. This paper proposes a technical support model for sustaining rural ICT projects. The model incorporates an e-portal that is linked to a service Cloud. The e-portal provides access to e-resources and experts in real-time. This can help to groom technical skills amongst ICT users and reduce the normal waiting time for technical support.
信息和通信技术是最通用的技术之一,对当今世界的所有部门都产生了重大影响。这些技术动态无缝集成到不同问题域的灵活性和能力使它们成为一种有吸引力的问题解决工具。然而,信息和通信技术的采用并非没有挑战。特别是在南非农村,信息和通信技术项目的可持续性,特别是在农村学校,仍然是一个潜在的障碍。协调一致的研究努力已经在维度上处理了可持续发展的主题,更多地关注于解决经济、社会文化和政治问题。但是,对信息通信技术基础设施至关重要的技术可持续性却很少或根本没有得到重视。考虑ICT模式的技术可持续性将挽救项目失败并避免资源浪费。本文提出了农村信息通信技术项目可持续发展的技术支持模型。该模型集成了一个链接到服务云的电子门户。电子门户提供对电子资源和专家的实时访问。这有助于培训信通技术用户的技术技能,并缩短技术支持的正常等待时间。

The role of social media may be considered as an important development in aiding crisis, thus the purpose of this study was to determine the factors influencing the use of social media during crises. An online survey of 44 respondents was conducted. The study revealed that there is a need for the use of social media in crises, however there were underlying factors contributing to the use of social media within this context. The analysis of the surveys together with the interviews revealed the perceptions of respondents as to the influencing factors which were security, privacy, and legislative frameworks. The study revealed the importance of social media in crisis communications but with limiting factors and a need for awareness within South Africa.
社交媒体的作用可以被认为是帮助危机的一个重要发展,因此本研究的目的是确定在危机期间影响社交媒体使用的因素。这项在线调查共有44名受访者参与。研究表明,在危机中有使用社交媒体的需要,然而,在这种情况下,有一些潜在的因素促成了社交媒体的使用。对调查和访谈的分析揭示了受访者对影响因素的看法,即安全、隐私和立法框架。该研究揭示了社交媒体在危机沟通中的重要性,但也有限制因素,需要在南非提高认识。

Efficient topology discovery for African NRENs 非洲nren的高效拓扑发现
Pub Date : 2016-05-11 DOI: 10.1109/ISTAFRICA.2016.7530684

The proliferation of under-sea and terrestrial fibre optic cables in Africa is leading to an evolution of the interconnection among Africa's National Research and Education Networks (NRENs). To fully monitor and track this evolution, NREN stakeholders and researchers need to continuously run active network measurements to map the inter-NREN topology. However, active topology measurement tools, such as Traceroute, introduce additional traffic in the network, which maybe undesirable for networks that have limited bandwidth. Furthermore, many network routers are configured to block/drop network probing packets, thereby making the task of topology discovery a lot more difficult. The paper aims to show that by carefully analysing Internet path overlaps, significant reductions can be made on the number of packets required to probe the topology. Furthermore, by using multiple probing protocols and vantage points, it is possible to alleviate the impact of blocked packets. The paper reports on a Traceroute study carried out on African NRENs, which shows that by jointly using different probing protocols, and taking into consideration path overlaps, it is possible to map all probe destinations, while achieving a 65% reduction in the number of probe packets sent.
非洲海底和陆地光纤电缆的扩散正在导致非洲国家研究和教育网之间相互联系的演变。为了充分监测和跟踪这种演变,NREN利益相关者和研究人员需要持续运行主动网络测量来绘制NREN内部拓扑。然而,活动拓扑测量工具(如Traceroute)会在网络中引入额外的流量,这对于带宽有限的网络来说可能是不可取的。此外,许多网络路由器被配置为阻止/丢弃网络探测数据包,从而使拓扑发现的任务变得更加困难。本文旨在表明,通过仔细分析互联网路径重叠,可以显著减少探测拓扑所需的数据包数量。此外,通过使用多个探测协议和有利位置,可以减轻阻塞数据包的影响。本文报告了对非洲NRENs进行的Traceroute研究,该研究表明,通过联合使用不同的探测协议,并考虑路径重叠,可以映射所有探测目的地,同时减少65%的探测数据包发送数量。

Access to quality, accurate and timely weather information is important. In order to improve weather information quality and quantity, increasing the number of operational Automatic Weather Stations, also referred to in this document as densification should be prioritized. In this paper, we provide research findings of a survey conducted from November 2014 to January 2015 to ascertain the status of weather stations in Uganda. Weather station density was found to be sparse and yet many of the available weather stations were non-functional. Based on the distribution of available operational weather stations, we are proposing densification strategies including climatological zones, security and land policies. To achieve sustainability of the weather stations, we commend improving human resources aspects among other things.
获得高质量、准确和及时的天气信息非常重要。为了提高天气信息的质量和数量,应优先增加在运行的自动气象站的数量,在本文件中也称为密集化。在本文中,我们提供了2014年11月至2015年1月进行的一项调查的研究结果,以确定乌干达气象站的状况。发现气象站密度稀疏,但许多可用的气象站是不正常的。根据现有业务气象站的分布情况,我们提出了包括气候带、安全和土地政策在内的密集化战略。为实现气象站的可持续发展,我们建议在其他方面改善人力资源。

User acceptance of legacy systems integration 用户对遗留系统集成的接受程度
Pub Date : 2016-05-11 DOI: 10.1109/ISTAFRICA.2016.7530602
Reuben L. Mathule, B. Kalema
Integrating and processing data that reside in different legacy systems remains an often laborious process, requiring either manual steps or complicated programming yet legacy systems when used in silos make the sharing of information, security and management controls a nightmare. Such fragmentation of data leads to challenges of system processing inefficiencies, poor synchronization of reports, delayed decision making and hinders quick response to business demands. This calls for the integration of legacy systems into a single repository system to enable a central processing of data and improve decision making. However, such integration is always resisted by user. The objective of this paper was to identify factors influencing user acceptance of Legacy system integration. Data for the study was collected by using a close-ended questionnaire from a government department in South Africa. The collected data was analysed quantitatively and results indicated that culture, trust, social influence, information quality, and system quality are core antecedents of the acceptance of Legacy systems integration. This paper examines the factors that contribute positively or negatively to the user acceptance of legacy systems integration as well as those factors that could be considered by system developers when modernizing legacy systems. Management within organizations could leverage the findings of this study when dealing with issues of technology acceptance. This paper further provides a model for a relatively influential factors that could be considered by managers, developers and researchers that need a way to integrate standard data sets that are distributed across legacy systems.
集成和处理驻留在不同遗留系统中的数据通常仍然是一个费力的过程,需要手动步骤或复杂的编程,而在筒仓中使用遗留系统时,共享信息、安全和管理控制是一场噩梦。这种数据碎片化导致系统处理效率低下,报告同步性差,决策延迟,阻碍对业务需求的快速响应。这需要将遗留系统集成到单个存储库系统中,以支持数据的中央处理并改进决策制定。然而,这种集成总是受到用户的抵制。本文的目的是确定影响用户接受遗留系统集成的因素。这项研究的数据是通过使用南非政府部门的封闭式问卷收集的。对收集到的数据进行了定量分析,结果表明文化、信任、社会影响、信息质量和系统质量是接受遗留系统集成的核心先决条件。本文考察了对用户接受遗留系统集成有积极或消极影响的因素,以及系统开发人员在对遗留系统进行现代化时可能考虑的那些因素。在处理技术接受问题时,组织内部的管理可以利用这项研究的结果。本文进一步为需要一种方法来集成分布在遗留系统中的标准数据集的管理人员、开发人员和研究人员可以考虑的一个相对有影响的因素提供了一个模型。

A smart city is a developed urban area that excels in the area of economy, governance, people and life through strong human capital, social capital and ICT infrastructure. It is a new approach to managing the complexity of city life, increase efficiency, reduce expenses and improve the quality of life of the citizens. This paper is on potential smart cities applications as applied to the domains of smart transport, smart tourism and recreation, smart health, ambient-assisted living, crime prevention and community safety, governance, monitoring and infrastructure, disaster management, environment management, refuse collection and sewer management, smart homes and smart energy. These smart cities applications support the future vision of cities, which aim at exploiting ICTs, namely internet of things technologies (IoT), for value-added service delivery. Furthermore, the paper presents a technical solution for energy control and comfort in a home for proof of concept of a smart city infrastructure application. The demonstrator described here is on how smart applications can manage energy control and comfort in a room that has a varied number of people and electrical appliances, with each being a source of heat.
智慧城市是指通过强大的人力资本、社会资本和信息通信技术基础设施,在经济、治理、人才和生活等方面表现出色的发达城市地区。它是一种管理复杂城市生活、提高效率、减少开支和改善市民生活质量的新方法。本文探讨了智慧城市在智能交通、智能旅游和娱乐、智能健康、环境辅助生活、预防犯罪和社区安全、治理、监测和基础设施、灾害管理、环境管理、垃圾收集和下水道管理、智能家居和智能能源等领域的潜在应用。这些智慧城市应用支持城市的未来愿景,旨在利用信息通信技术(即物联网技术)提供增值服务。此外,本文还提出了一种用于家庭能源控制和舒适的技术解决方案,以证明智慧城市基础设施应用的概念。这里描述的演示是关于智能应用程序如何在一个房间里管理能源控制和舒适度,房间里有不同数量的人和电器,每一个都是热源。

mHealth has revolutionized the health care service delivery at all levels of health care system in both developing and developed world. Both at patient level and service provider level, mHealth has become very useful in areas of decision support, data storage, data processing into useful information, information flow and information use just to mention a few. For service providers with multiple service deliveries, there is a challenge in managing well the various mHealth applications across the various program deliveries. Standalone applications on different phones or the same phone poses a number of challenges and complications in management and use of these individual applications for patients across the health system. One solution to such challenges is the use of integrated mHealth solutions. With mHealth integrated application, we can address the challenge of health workers having multiple phones and applications for use in various service deliveries which often target the same audience. Integration also facilitates the continuity of care of patients across different services usually provided by the same health service point. Integration also ensures optimum use of resources thereby redirecting further resources to other needed areas. For optimal results of integration process, it is important to clearly define the problem, outline the intervention in line with the entire health care system and provide for means to mitigate risks. As a rule of thumb, intensive verification, validation and testing of the integrated application is crucial to ensuring an acceptable solution that improves the health care of people. Documenting the processes and learning from the them is important in improving the next possible intervention. This paper discusses the motivation, approach and outcomes of the integration process of mHealth applications.
移动医疗已经彻底改变了发展中国家和发达国家各级卫生保健系统的卫生保健服务。无论是在患者层面还是在服务提供商层面,移动医疗在决策支持、数据存储、数据处理转化为有用信息、信息流和信息使用等领域都变得非常有用,仅举几例。对于有多种服务交付的服务提供商来说,在不同的项目交付中管理好各种移动医疗应用程序是一个挑战。不同手机或同一手机上的独立应用程序在整个卫生系统中管理和使用这些单独的应用程序时带来了许多挑战和并发症。应对这些挑战的一个解决方案是使用综合移动医疗解决方案。通过移动医疗综合应用程序,我们可以解决卫生工作者拥有多种手机和应用程序以提供各种服务的挑战,这些服务通常针对同一受众。一体化还促进了通常由同一保健服务点提供的不同服务之间对患者护理的连续性。整合还确保资源的最佳利用,从而将进一步的资源重新定向到其他需要的领域。为了使整合过程取得最佳效果,明确问题,概述符合整个卫生保健系统的干预措施,并提供减轻风险的手段是很重要的。根据经验,对集成应用程序进行深入的验证、确认和测试对于确保提供可接受的解决方案以改善人们的医疗保健至关重要。记录这些过程并从中学习,对于改进下一个可能的干预措施非常重要。本文讨论了移动健康应用集成过程的动机、方法和结果。

For optimal results of integration process, it is important to clearly define the problem, outline the intervention in line with the entire health care system and provide for means to mitigate risks. As a rule of thumb, intensive verification, validation and testing of the integrated application is crucial to ensuring an acceptable solution that improves the health care of people. Documenting the processes and learning from the them is important in improving the next possible intervention. This paper discusses the motivation, approach and outcomes of the integration process of mHealth applications.","PeriodicalId":326074,"journal":{"name":"2016 IST-Africa Week Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127645847","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}

The entertainment industry world-wide provides lucrative business opportunities, and within South Africa, this market is still underdeveloped, especially within rural communities. Within this context, the FP7 MOSAIC 2B project aimed to empower micro-entrepreneurs by providing them with a Cinema-in-a-Backpack, which is a set of equipment allowing them to screen movies in rural areas within South Africa. However, to ensure compliance, these micro-entrepreneurs had to acquire the necessary licenses, which proved to be challenging given the regulatory environment as well as the different stakeholders involved. Using a systematic literature review as well as the MOSAIC 2B project as a case study, this paper reports on an investigation on the process and procedure necessary for a micro-entrepreneur to acquire licenses in order to screen multimedia content within rural South Africa. The paper provides an overview of the regulatory landscape as well as the nature of the film industry in South Africa. The main contribution of the investigation is a process model that could be used by a microbusiness to understand the requirements and process to follow when acquiring a legal licence for the screening of multi-media content within South Africa.
全世界的娱乐业提供了利润丰厚的商业机会,而在南非,这个市场仍然不发达,特别是在农村社区。在此背景下,FP7 MOSAIC 2B项目旨在通过向微型企业家提供“电影背包”(Cinema-in-a-Backpack)来增强他们的能力,这是一套设备,使他们能够在南非农村地区放映电影。然而,为了确保遵守规定,这些微型企业家必须获得必要的许可证,鉴于监管环境以及所涉及的不同利益攸关方,这证明是具有挑战性的。本文采用系统的文献综述和MOSAIC 2B项目作为案例研究,报告了一项关于微型企业家获得许可证以在南非农村放映多媒体内容所需的过程和程序的调查。本文概述了南非的监管环境以及电影业的性质。这项调查的主要贡献在于提供了一个流程模型,供微型企业了解在南非境内获得多媒体内容筛选法律许可时需要遵循的要求和流程。

Online Identification and Authentication is an essential requirement for providing e-services. Few studies have investigated the challenges facing e-Government and IDM in developing countries and, to the best of our knowledge, none of the existing research has studied the challenges facing online identification and remote authentication in developing countries, such as the North Africa Countries (NAC), where a relatively large proportion of citizens are illiterate. Therefore, the design of a national IDM system in a NAC must explicitly consider illiteracy to allow this group of citizens to benefit from online services. Egypt is one of the NAC, which has implemented online identification and authentication services that are widely recognized as the most advanced among the NAC. This paper analyses the Egyptian digital IDM in order to identify IDM requirements for online identification and authentication services that guarantee equal access to online services and an inclusive society. The study identifies strengths and weaknesses of the Egyptian e-Government and IDM services, which we believe are common to most NAC, since the NAC are quite similar in terms of social culture, citizen's education level and skills, citizen's behaviours, digital infrastructure and legislation, but also common to many other developing countries. Our analysis of the Egyptian e-Government services indicates that the security requirements and principle of equal access are not fully met, which illustrates the difficulty of introducing e-Government in developing countries.
在线识别和认证是提供电子服务的基本要求。很少有研究调查了发展中国家电子政务和IDM面临的挑战,据我们所知,现有的研究中没有一项研究研究了发展中国家(如北非国家)面临的在线识别和远程认证挑战,这些国家的公民中有相当大比例是文盲。因此,NAC国家IDM系统的设计必须明确考虑文盲,以使这一群体的公民从在线服务中受益。埃及是NAC之一,已经实施了被广泛认为是NAC中最先进的在线身份认证服务。本文分析了埃及的数字IDM,以确定IDM对在线识别和认证服务的要求,以保证在线服务的平等获取和包容性社会。该研究确定了埃及电子政务和IDM服务的优势和劣势,我们认为这是大多数NAC的共同之处,因为NAC在社会文化、公民教育水平和技能、公民行为、数字基础设施和立法方面非常相似,但也与许多其他发展中国家相似。我们对埃及电子政务服务的分析表明,埃及的电子政务服务并没有完全满足安全要求和平等获取原则,这说明了在发展中国家引入电子政务的困难。
