Closed Environment

This chapter reports on a case study linking several technology devices that monitor a range of vital signs in patients recently discharged to a hospital ward from the Intensive Care Unit (ICU). Apart from presenting an interesting technological challenge, this closed environment creates unique logistical and physical ergonomic challenges as well as cognitive and perceptual design problems for mobile technology. Devices include desktop computers, touch monitors, and several types of remote mobile devices including PDAs. A number of important design issues are addressed, such as deciding which visual details can be safely eliminated from a small display, or if permission should be given to turn off the alarm functions, among others. Lack of direct access to users compromised the ecological validity of several parts of the evaluation and alternative evaluation methods had to be devised.

E Learning

A multiplatform e-learning system called the “Graphical Partitioning Model (GPM)”, with the separate versions for desktop computers and mobile devices, was developed for learning knowledge of fraction equivalence. This chapter presents a case study on the use of the mobile version GPM for the learning of the targeted topic in a mobile technology supported environment. The interactions between a dyad of Primary 5 students and the GPM were analyzed in order to understand the feasibility of the design of the mobile version e-learning system. The results show that the interactions between the students and the GPM have the potential to enhance the learning effectiveness of the targeted topic. The mobile version GPM demonstrated a possibility to integrate with collaborative learning strategies such as reciprocal tutoring and peer discussion. The case study also reveals that there is a potential for the flexible use of the dual-version GPM to foster deep learning.

Abstract Over the years, failures induced by an electrostatic discharge (ESD) have become a major concern for semiconductor manufacturers and electronic equipment makers. The ESD events that cause destructive failures have been studied extensively [1, 2]. However, not all ESD events cause permanent damage. Some events lead to recoverable failures that disrupt system functionality only temporarily (e.g. reboot, lockup, and loss of data). These recoverable failures are not as well understood as the ones causing permanent damage and tend to be ignored in the ESD literature [3, 4]. This paper analyzes and characterizes how these recoverable failures affect computer systems. An experimental methodology is developed to characterize the sensitivity of motherboards to ESD by simulating the systemlevel ESD events induced by computer users. The manuscript presents a case study where this methodology was used to evaluate the robustness of desktop computers to ESD. The method helped isolate several weak nets contributing to the failures and identified a design improvement. The result was that the robustness of the systems improved by a factor of 2.

There has been an explosion in the development of electronic methods for psychological assessment. These include use of handheld devices, desktop computers, and platform-based Internet methods. This development has occurred separately in the commercial environment and in the research environment. This development of new methods presents great promise to improve the accuracy, ecological validity, and range of constructs in psychological assessment. However there are also many problems involved in the development of these electronic methods, including the need to train clinicians in their use, the need to develop safeguards for privacy, and the need to develop methods to ensure the integrity of the data collected. This chapter outlines some of the main considerations in moving forward.

Client Side

Increasing demands on user interface (UI) usability, adaptability, and dynamic behavior drives ever-growing development and maintenance complexity. Traditional UI design techniques result in complex descriptions for data presentations with significant information restatement. In addition, multiple concerns in UI development leads to descriptions that exhibit concern tangling, which results in high fragment replication. Concern-separating approaches address these issues; however, they fail to maintain the separation of concerns for execution tasks like rendering or UI delivery to clients. During the rendering process at the server side, the separation collapses into entangled concerns that are provided to clients. Such client-side entanglement may seem inconsequential since the clients are simply displaying what is sent to them; however, such entanglement compromises client performance as it results in problems such as replication, fragment granularity ill-suited for effective caching, etc. This paper considers advantages brought by concern-separation from both perspectives. It proposes extension to the aspect-oriented UI design with distributed concern delivery (DCD) for client-server applications. Such an extension lessens the serverside involvement in UI assembly and reduces the fragment replication in provided UI descriptions. The server provides clients with individual UI concerns, and they become partially responsible for the UI assembly. This change increases client-side concern reuse and extends caching opportunities, reducing the volume of transmitted information between client and server to improve UI responsiveness and performance. The underlying aspect-oriented UI design automates the server-side derivation of concerns related to data presentations adapted to runtime context, security, conditions, etc. Evaluation of the approach is considered in a case study applying DCD to an existing, production web application. Our results demonstrate decreased volumes of UI descriptions assembled by the server-side and extended client-side caching abilities, reducing required data/fragment transmission, which improves UI responsiveness. Furthermore, we evaluate the potential benefits of DCD integration implications in selected UI frameworks.

Background: Ethiopia has been landlocked since Eritrea, a former province, gained independence. Its imports and exports by sea are now sent via neighbouring coastal states, mainly Djibouti, and it needs to ensure sustainable access to multiple transit corridors.Objective: This article aims to evaluate alternative transit corridors to Ethiopia in terms of basic port infrastructure, and logistics costs. The findings provide insights to inform policy on securing reliable maritime access to the country.Method: This study adopts a case study approach by using secondary data to evaluate alternative transit corridors. Following a critical review of theoretical and empirical literature, descriptive statistics are presented using tables, graphs and charts.Results: Low-cost, high-capacity and high-frequency global maritime freight trade is easier through Djibouti than through Mombasa in Kenya or Port Sudan, owing to its better liner shipping connectivity. Thus, Ethiopia should continue to import containerised cargo through the Port of Djibouti. However, direct access to the sea is also important for national defence and security.Conclusion: Ethiopia should therefore secure access through multiple ports to safeguard national security, regardless of economic feasibility. This can be realised by directing break-bulk, dry bulk and petroleum products through ports in Sudan and Kenya. In addition, particular emphasis should be given to seaports closest to the country’s economic centre, such as Berbera in Somaliland and Asseb and Massawa in Eritrea.

Remote Patient

Radio-based signalling devices will play an important role in future generations of remote patient monitoring equipment, both at home and in hospital. Ultimately, it will be possible to sample vital signs from patients, whatever their location and without them necessarily being aware that a measurement is being taken. This paper reviews current methods for the transmission by radio of physiological parameters over ranges of 0.3, 3 and 30 m, and describes the radiofrequency hardware required and the carrier frequencies commonly used. Future developments, including full duplex systems and the use of more advanced modulation schemes, are described. The paper concludes with a case study of a human temperature telemeter built to indicate ovulation. Clinical results clearly show the advantage to be had in adopting radio biotelemetry in this instance.
