In R01HD098027 we have rolled out our Africa Brain Powered Games (BPG) tablet-based games app for use with HIV-affected children at our Kampala Uganda and Blantyre Malawi study clinic sites. BPG is a package of cognitive training games originally clinically tested (with NIH support) with HIV+ school children in Uganda. As a child plays, BPG gathers game data for neurocognitive assessment. During the lockdowns in 2020-2021 associated with COVID-19 outbreak in Uganda, we shifted BPG sessions from the clinic to the participant’s homes. Developing a cloud architecture would allow us to deliver content and receive data faster given the distributed nature of the cloud structure. If we could manage neurocognitive training app requests using the cloud-based integrated network of many servers, local mobile network bandwidth constraints in Africa could be circumvented. Real-time data requests could be scaled up to meet demand and therefore, not overwhelm a single local server. This is the overarching goal of making our computer-based assessment/rehabilitative apps with at-risk African children “cloud-ready” with the support of this supplemental grant. In Study Aim 1 we will evaluate concurrent and predictive validity of BPG and a newly developed prosocial game of reasoning and planning called Village Builder (VB) to other proven computer-based and testing battery indicators of brain/behavior integrity of neurocognitive function. Supplemental Development Activity for Study Aim 1. The software development activities most relevant to our 1st study aim is re-factoring software to scale efficiently to the cloud. Cloud-readiness consulting experts will work with R01 co-investigator and BPG and VB apps developer Professor Brian Winn to move the apps developed in his “serious games for entertainment and learning” (GEL) lab from the LAMP (Linux, Apache, MySQL, PHP) web stack to AWS or other cloud providers. We will then move our current PHP API used for internet-based data gathering to a REST API componentized application. Supplemental Development Activity for Study Aim 2 involves provisioning of standard source code structure, documentation, version management, build and test support in codebases that promotes community open-source enhancement. We will do so with such provisioning tools as Git/GitHub, that we have use for other software adaptations to the cloud. Prof. Winn’s GEL lab programmers will utilize JSON (JavaScript Object Notation). Most of the REST APIs and any native cloud services are going to utilize JSON as our R01 training/assessment apps (BPG and VB) are transitioned for cloud readiness in this supplemental software development initiative. Supplemental Development Activity for Study Aim 3 will pilot test the usability, interoperability and scalability of BPG under increasing internet real-time bandwidth at both sites (Uganda and Malawi). These include making use of enhanced hardware and clustering technology. Conclusion. This administrative supplement allows us to effectively interfacing the cloud to mobile-based internet real-time BPG and VB app management in the child’s home environment.

在R 01 HD 098027中，我们推出了基于Africa Brain Powered Games（BPG）平板电脑的游戏应用程序， 在我们的乌干达坎帕拉和马拉维布兰太尔研究诊所，BPG是一个包 认知训练游戏最初在乌干达的艾滋病毒阳性学童中进行临床测试（在NIH的支持下）。 当孩子玩游戏时，BPG收集游戏数据进行神经认知评估。在2020-2021年的封锁期间 与乌干达的COVID-19疫情相关，我们将BPG会议从诊所转移到参与者的 木屋.开发云架构将使我们能够更快地交付内容和接收数据， 云结构的分布式特性。如果我们可以使用 基于云的集成网络的许多服务器，在非洲本地移动的网络带宽的限制， 被规避。实时数据请求可以按比例增加以满足需求，因此，不会压倒一切 一个本地服务器这是使我们基于计算机的评估/康复的首要目标 在这笔补充赠款的支持下，有风险的非洲儿童的应用程序“云就绪”。在研究目标1中 我们将评估BPG和一个新开发的亲社会游戏的并发和预测有效性， 推理和规划称为村建设者（VB），以其他证明基于计算机和测试电池 神经认知功能的大脑/行为完整性的指标。补充开发活动 研究目的1.与我们的第一个研究目标最相关的软件开发活动是重构软件 高效地扩展到云端。云就绪咨询专家将与R 01合作研究员合作， BPG和VB应用程序开发者Brian Winn教授将在他的“严肃游戏”中开发的应用程序 从LAMP（Linux、Apache、MySQL、PHP）Web堆栈到AWS或 其他云供应商然后，我们将把当前用于基于互联网的数据收集的PHP API移动到 REST API组件化应用程序。研究目标2的补充开发活动包括 提供标准源代码结构、文档、版本管理、构建和测试支持 in codebases代码库that promotes促进community社区open开源enhancement增强.我们将使用这些配置工具来实现这一点 作为Git/GitHub，我们可以使用其他软件来适应云。Winn教授的凝胶实验室 程序员将使用JSON（JavaScript Object Notation）。大多数REST API和任何原生云 服务将使用JSON，因为我们的R 01培训/评估应用程序（BPG和VB）将过渡到 云就绪性在此补充软件开发计划中。补充开发活动 研究目标3将在互联网不断增长的情况下对BPG的可用性、互操作性和可扩展性进行试点测试 这两个地点（乌干达和马拉维）的实时带宽。这些措施包括利用增强的硬件， 集群技术结论这一行政补充使我们能够有效地与 基于云到移动的互联网实时BPG和VB应用程序管理在孩子的家庭环境。
