The paper will discuss a study reflecting the changes in design and exploitation of an existing standard merchantman when the existing diesel propulsion plant is replaced by a gas turbine using a well-proven and inherently safe nuclear heat source. Subjects which will be discussed are: 1. why this study was done, 2. the NEREUS propulsion installation which is considered for this “replacement”, 3. the nuclear part and the non-nuclear part of the NEREUS installation, 4a. safety matters regarding the small-scale nuclear plant, 4b. safety matters regarding the nuclear propulsion plant (the maritime version), 5. fuel availability, 6. place of the nuclear propulsion plant in the ship in view of the weight, 7. required and no longer required auxiliary installations for the nuclear energy plant, 8. restrictions for ship operations, 9. manoeuvring, exploitation and manning of the ship, 10. logistic support of the installation.

The Many

The work of instructional design (ID) requires new content learning, which often requires various types of published or secondary research as well as direct elicitations from the cooperating subject matter experts (SMEs) about the topic. For instructional design projects, both design and development, a range of information is required: who the target learners are; what content knowledge is required (as knowledge, skills, and abilities); what pedagogical designs may be most effective; what technologies will be required for the build; what learning sequences, objects, assignments, and assessments are needed; what legal and technological standards need to be abided by. This work describes research strategies for instructional design, research documentation, research citations, and applying the many acquired research insights to the instructional design and development work.

Summary Objectives: The paper explores possibilities for situating IT design and development work within the context of use so as to support the co-realisation of technology and ‘design in use’. The aim is to build a new understanding between IT professionals and users which is grounded upon what happens as the latter grapple with the problems of applying IT, appropriating its functionalities and affordances into their work practices and relations. Methods: Following a discussion of participatory design and ethnomethodology, a novel method called co-realisation, which aims to provide a synthesis of the preceding methods, is suggested as an alternative. Through a discussion of findings from a case study of IT systems design and development in healthcare we show how the co-realisation approach might provide work-affording systems and how user-designer relations might be reformulated. We suggest that work-affording systems can be developed through the deployment of an engaged facilitator who works with the users to unpack the work site-specific potentialities of technology. Results: The case study shows how risk of non-adoption might be minimised through the development of partnerships, and how the presence of the facilitator in the workplace capitalises on the mundane work undertaken therein and how the facilitator might work with the users to develop artefacts that support this work as opposed to reconfiguring it. Conclusions: The case study illustrates co-realisation in action and how it might be seen to reconfigure relations between users and designers in a way that appears productive. Co-realisation can help address the widely observed problem of IT systems failures in healthcare.

This paper is a report on the design and development of a small regenerative gas turbine and on the component technology involved in this development. It is shown — on the basis of test results — that the gas turbine is a potential competitor of the Diesel engine for powering trucks, if the economy of the gas turbine can be improved. Future development work must therefore be aimed at improving the efficiency of the individual components and at applying ceramic materials in the hot parts of the engine.
