FEEDBACK (Psychology), PROTOTYPES, RAPID prototyping, SEMI-structured interviews, MEDICAL equipment, and SET design
Engineering designers frequently use prototypes to gather input from stakeholders. Design guidelines recommend the use of quick and simple prototypes early and often in a design process. However, the type and quality of a prototype can influence how stakeholders perceive a new design concept and can, therefore, impact their responses. Additionally, different levels of experience, expertise, and preparedness for providing input to designers may lead stakeholders from different geographical or cultural settings to provide different responses, making the format of a prototype even more influential. Although design practitioners are known to intentionally align their prototyping approaches with the specific design question to be answered, it is unclear the extent to which prototyping approaches should vary based on the stakeholder, context, and setting of a design project. To investigate how the format and quality of prototypes influence stakeholders' responses, we conducted a field study with various medical professionals in Ghana. We presented prototypes for a medical device in different formats to stakeholders and collected responses to the design through semi-structured interviews. Our findings indicate that professional expertise, prototype format, and question type influenced the types of responses that stakeholders provided. These findings suggest that designers seeking input from stakeholders on new concepts should consider context-specific prototyping strategies, especially when designing at distance and across cultures.

COMMUNITY health nursing, RAPID prototyping, PERIODIC health examinations, NATIONAL competency-based educational tests, ONLINE education, and CONTINUING education
This study was conducted to develop an online education program for visiting health nurses on National Health Examination. The study period was from November 2016 to December 2017. The program was developed in stages using rapid prototyping methodology. 1) Learners' needs were identified through literature review and focus group interviews (FGIs) with visiting health nurses and stake-holders in the field. 2) The contents of the education program including counseling strategies regarding the heath of visiting health nurses were developed. 3) Online education materials were developed and piloted amongst learners. 4) The contents of educational programs were classified into eight learning modules, and online education drafts were pilot tested. 5) Based on feedback from learners, this program was revised and a web-based continuing education program for community nurses was developed. These education programs effectively assisted nurses with counseling regarding health examinations during visiting health nursing care. Therefore, the online continuing education program may be a very effective educational approach to improving nurses competency. [ABSTRACT FROM AUTHOR]
Additive manufacturing technologies are quickly becoming more accessible and are being integrated in the workflow of the manufacturing industry. These technologies are often used for prototyping in the product design process. However the fact that there is a limited choice of printing materials means that prototypes of rubber components can rarely be printed from the desired material as used for real production. This paper investigates the possibility of producing prototypes of vulcanised rubber components by injection moulding process using 3D-printed Polyether Ether Ketone (PEEK) inserts. This would allow the production of a batch of rubber parts without needing to produce a metal mould, which is both costly and time consuming [ABSTRACT FROM AUTHOR]
