BACKGROUND Our case describe a rare recurrence case of Unicentric Castleman's disease (UCD) with hyaline vascular type 14 years after surgery. CASE PRESENTATION A 35-year-old Chinese female was admitted to hospital with one and half months history chest distress and chest pain. Patient reports a history of thoracic operation for mediastinal mass 14 years ago, and it was diagnosed UCD with hya...

Majority of agile projects currently involve interactive user interface designs, which can only be possible by following UCD in agile software model. But the integration of UCD is not clear in the current agile models. Both Agile models and UCD have iterative nature but agile models focus on coding and development of software; whereas, UCD focuses on user interface of the software. Similarly, b...

Situation awareness is a variety of cognitive processes employed by operators in a complex and dynamic environment to understand the current state of the environment in order to know its future state. Information systems designed on the principle of situation awareness adopt the technique of user-centred design (UCD) methodology. A UCD approach involves users in system development process to ma...

A team of researchers are engaged in a UserCentered Design (UCD) approach to develop the Instructional Module Development System (IMOD), i.e., a software program that facilitates course design. This paper describes the results of the focus groups, and surveys facilitated to elicit feedback from potential users on the features and usability of the IMOD system. Keywords—instruction design; outcom...

IBM’s traditions in human factors are rooted as far back as the 1950s. This article traces and describes how the challenges to the discipline have changed over the last 40 years, based on the personal and professional experiences of the authors. During that span of time, the focus of attention has shifted from traditional knobs and dials hardware, to system and application software, and now to ...

User-centered design (UCD) is well recognized as an effective human factor engineering strategy for designing ease of use in the total customer experience with products and information technology that has been applied specifically to health care information technology systems. We conducted a literature review to analyze the current research regarding the use of UCD methods and principles to sup...

We detail the tussle between the rigour and effectiveness of user studies for the user-centred design of technologies, drawing on the authors’ experience within a UCD team. This discussion is as much a challenge between UCD researchers coming from different disciplines as it is between the UCD team and the technologists.

User-Centered Design (UCD) is proposed in literature as an ideal engineering method to guarantee the usability of interactive systems. In practice, however, most enterprises are rather sceptical about the benefits of UCD for in-house or outsourced developments, e.g. due to perceived complexity, duration and cost of the UCD approaches. In this paper, we describe the actual lessons learnt after c...
