The paper explores the effectiveness of persona-based design methods in HCI education. We describe the experiences of our students in learning, practicing, and using personas in a number of design contexts. From these experiences, we identify common patterns of use and misuse and characterize challenges in incorporating and using personas in the classroom. We conclude with advice on how to effe...

This SIG will facilitate a debate concerning how best to support the development of indigenous HCI in developing countries, both as part of education and training systems and within industrial practice.

In an attempt to determine whether, following intravenous injection of hypertonic solutions of sodium chloride, an increased amount of this salt could be detected in the cerebra-spinal fluid, it was noted that within a short time after the intravenous injection, cerebra-spinal fluid could not be obtained when the subarachnoid space was entered. This observation led at once to the attachment of ...

The contribution of this paper is twofold: (1) a novel fault injection attack against AES, based on a new fault model, is proposed. Compared to state-of-the-art attacks, this fault model advantage is to relax constraints on the fault location, and then reduce the a priori knowledge on the implementation. Moreover, the attack algorithm is very simple and leaves room for optimization with respect...

Based on the available evidence, the Therapeutics and Technology Assessment subcommittee concluded that 1) epidural steroid injections may result in some improvement in radicular lumbosacral pain when assessed between 2 and 6 weeks following the injection, compared to control treatments (Level C, Class I–III evidence). The average magnitude of effect is small and generalizability of the observa...

BACKGROUND SurePal™ is a reusable self-injection system that has been developed to support daily administration of Omnitrope(®) (Sandoz, Kundl, Austria). A questionnaire-based cross-sectional survey was conducted to evaluate acceptability of, and preference for, SurePal™ in pediatric patients who were prescribed treatment with Omnitrope(®) within routine clinical care. METHODS This multicente...

We study the strength of certain obfuscation techniques used to protect software from reverse engineering and tampering. We show that some common obfuscation methods can be defeated using a fault injection attack, namely an attack where during program execution an attacker injects errors into the program environment. By observing how the program fails under certain errors the attacker can deduc...

the purpose of this study is to investigate the effect of injection parameters on a heavy duty diesel engine performance and emission characteristics. in order to analyze the injection and spray characteristics of diesel fuel with employing high-pressure common-rail injection system, the injection characteristics such as injection delay, injection duration, injection rate, number of nozzle hole...
