Purpose - The purpose of this paper is to propose a template-based framework for nasal prosthesis fabrication using a 3D areal scanner and a CT scanner. Design/methodology/approach - Use of a self-designed 3D areal scanner enables acquisition of accurate data describing the patient's face. Patients with nasal defects have no organization for reference, but the template-based model construction method can ensure successful building of the outer surface of the nasal prosthesis. Since the areal scanner has some difficulties acquiring data for concave areas, preoperative CT data are used to provide concave information, enabling construction of the inner surface for the nasal prosthesis. The combined inner and outer surfaces are used to generate the completed nasal prosthesis. Findings - The results showed that the nasal prosthesis fits the patient's appearance well. Clinical applications confirmed that this framework is attractive and has the potential desired nasal prosthesis in daily clinical practice. Practical implications - The results of this study improve the fabrication accuracy of nasal prostheses. The construction and development technique employs a nasal digital library, 3D areal scanning data and CT scanning data. This technique facilitates fabrication of precise nasal prostheses while helping the patients predict the effect before the prosthesis is manufactured. Originality/value - This template-based framework has strong potential for clinical applications because of its advantages over other methods in terms of accuracy, speed, safety, and cost. © Copyright - 2013 Emerald Group Publishing Limited.

To develop green products and to develop products in green are becoming a pursuit of leading companies in world. Modularity is one of key technologies to realise these goals. It is found that modularity can promote the betterment of products and their performances, can decrease the investments in new products or variants' development, can greatly reduce the activities and processes in a product life cycle and can cut down the resource consumptions in management and engineering. An integrated modularity approach is brought forward for green product development (GPD) to enhance environmental performance. Seven types of modularity are introduced and arranged in an integrated modularity process to implement the approach with a metric system. The integrated modularity incorporates all the benefits of modularity into the activities of GPD. The proposed approach is helpful for a company to achieve efficient product development with low resource consumption. © 2011 Inderscience Enterprises Ltd.

Information technology has promoted our society gradually into knowledge economy from product economy. Value creation requires more and more knowledge and information to support enterprise activities. Knowledge management (KM) as an activity has already existed, and will make the organisation and individual have stronger competition strength, and make better decisions. In order to respond to the industrial trend towards knowledge management, this paper investigates and proposes a framework for product lifecycle knowledge management that utilises product maintenance data across the lifecycle of the product. A case presented in this paper is a maintenance knowledge service system to prove the framework method. © 2014 Taylor and Francis.
