This article describes the design and implementation of LiftingDoneRight, a novel system for healthcare professionals to enhance their compliance with best practices and regulations regarding proper body mechanics for lifting and pulling activities. The system uses Microsoft Kinect to track the motion of consented users non-intrusively. The system relies on the use of a smartwatch to deliver an alert via vibration and text display whenever a wrong activity that violated the proper body mechanics has been detected. A core contribution of this study is a registration mechanism for a healthcare professional to explicitly give permission to the system to monitor his or her activities. Furthermore, a non-intrusive biometrics-based single sign-on mechanism is incorporated into the system to allow a user to be automatically identified for tracking as long as the user has manually registered with the system before. Finally, the system offers a number of configurations to accommodate different usability needs and privacy requirements.

The technology based learning systems have capability to comply with diverse requirements of all the stakeholders in the modern education system. In technology based modules, such as those taught in Mechanical Engineering courses, the psychomotor content takes precedence over other domains of teaching and learning. Effective integration of pedagogical content within the Mechanical Engineering modules is of utmost importance for effectiveness in teaching and learning processes in these modules. Published literature is limited in this regard, and hence, the present study focuses on developing a novel an information quality framework for Mechanical Engineering modules, through which an enhanced treatment has been provided to the pedagogical content, in order to meet the educational goals and the industrial requirements worldwide. The novel information quality framework developed in the present study can be used as a guideline for measuring the effectiveness of Mechanical Engineering modules.

The vast amount of information brought about by the use of Information Technologies can sometimes pose a challenge to decision makers about the relevance and effectiveness of certain information. This paper proposes a Mobile Decision Support System (MDSS) suitable for Higher Learning institution. To arrive to the proposed design, researchers used traditional research techniques such a questionnaire and interview to understand the way decision makers operate in their respective organizations. Using four higher learning institutions located in Dar es Salaam as case study, data were collected, digitized and analyzed. Results showed that despite having access to computers and other forms of information technologies, most decision makers rely on tradition methods such word of mouth, document review and meetings to arrive to most of their decisions. Many participants expressed their skepticism on the state of the information and communication technologies (ICT) infrastructures as some turned to their subordinates and offline sources as their convenient ways to gather information.

With the advancement of portable devices and sensors, there has been a need to build a universal framework, which can serve as a nodal point to aggregate data from different kinds of devices and sensors. We propose a unified framework that will provide a robust set of guidelines for sensors with varied degree of complexities connected to common set of System-on-Chip (SoC). These will help to monitor, control and visualize real time data coming from different type of sensors connected to these SoCs. We have defined a set of APIs, which will help the sensors to register with the server. These APIs will be the standard to which the sensors will comply while streaming data when connected to the client platforms.
