Abstract The essay introduces MapTap, a research project that zooms in on the ever-changing social networks underpinning Flemish tapestry (1620 – 1720). MapTap develops the young and still slightly amorphous field of Formal Art Historical Social Network Research (FAHSNR) and is fueled by Cornelia, a custom-made database. Cornelia’s unique data model allows researchers to organize attribution and relational data from a wide array of sources in such a way that the complex multiplex and multimode networks emerging from the data can be transformed into partial unimode networks that enable proper FAHSNR. A case study revealing the key roles played by women in the tapestry landscape shows how this kind of slow digital art history can further our understanding of early modern creative communities and industries.

Matching Procedure

The wide range of skin tones in the Asian population presents a challenge when colour-matching hand and finger prostheses. It requires that the prostheses be custom-made to better match the wide variations. We have developed a finger and hand prosthesis using a multi-layered moulding technique incorporating a colour-matching procedure capable of reproducing the colour tones and life-like appearance of the skin. Between 1990–1994, we have fitted these prostheses to a total of 109 patients. In evaluating the colour-match of their prostheses, 84% of the patients fitted with hand prostheses and 78% of those fitted with finger prostheses had a good to excellent match. This paper discusses some of the challenges we face in colour-matching hand and finger prostheses in the Asian population.

AbstractThe article raised issues related to the design and execution of low-energy objects in Polish conditions. Based on the designed single-family house, adapted to the requirements of the National Fund for Environmental Protection and Water Management (“NF40” standard), the tools to assist investment decisions by investors were shown. An economic analysis and a multi-criteria analysis were performed using AHP method which had provided an answer to the question whether it is worthwhile to bear higher investment costs in order to adjust to the standards of energy-efficient buildings that fulfil a minimal energy consumption's requirements contained in Polish law. In addition, the variant of object that had optimal characteristics due to the different preferences of investors was indicated. This paper includes analysis and observations on the attempts to unify that part of the building sector, which so far is considered to be personalized, and objects in accordance with the corresponding idea are designed as “custom-made”.

This case study describes a total tibia resection and reconstruction with a custom-made endoprosthetic replacement (EPR) and a long-term, 8-year follow-up. The patient underwent a total tibia adamantinoma resection in 2009. Reconstruction was performed with a custom-made total tibia EPR, where both the knee joint and ankle joint were reconstructed. Two muscle flaps, latissimus dorsi free flap and a pedicled medial gastrocnemius flap, were used for soft tissue reconstruction. The patient returned to normal life as a kindergarten teacher, without complications for eight years. This case demonstrated the importance of successful multidisciplinary teamwork in close collaboration with industry. In our best knowledge, no over 2 years of follow-up of total tibia replacement reports have been published.

Abstract Additive Manufacturing (AM) has been identified as a key enabler for Mass Customization (MC) due to its negligible tooling cost associated with producing one-off items. This is especially valuable for the medical industry where the ability to create patient-specific products can greatly improve performance and comfort. However, the use of AM so far has only been limited to previously custom-made devices due to the prohibitive design costs associated with a knowledge-intensive and highly manual design process. The research community has often overlooked this area and as yet no study has shown a completely automated process that can reduce or even eliminate this design cost for existing mass-produced ergonomic products (e.g. respirators). This study investigates the methodology of developing a completely automated design pipeline through a case study on Continuous Positive Airway Pressure (CPAP) mask. Through a parametric design approach, a fully automated pipeline was constructed based on a large-scale statistical shape model “learnt” from 9,663 high-resolution facial scans. The pipeline accepts a single “in-the-wild” facial image as the only data input and produces a CAD model of CPAP mask in under a minute. The significant reduction in design time, ease of data acquisition and the complete removal of a manual CAD modelling process can make AM more accessible for CPAP masks manufacturers. The same workflow can potentially be employed to construct automation pipelines for other types of wearables, therefore encouraging the adoption of AM for MC of a wider selection of products.

End Use

In craniomaxillofacial surgical procedures, an emerging practice adopts the preoperative virtual planning that uses medical imaging (computed tomography), 3D thresholding (segmentation), 3D modeling (digital design), and additive manufacturing (3D printing) for the procurement of an end-use implant. The objective of this case study was to evaluate the cumulative spatial inaccuracies arising from each step of the process chain when various computed tomography protocols and thresholding values were independently changed. A custom-made quality assurance instrument (Phantom) was used to evaluate the medical imaging error. A sus domesticus (domestic pig) head was analyzed to determine the 3D thresholding error. The 3D modeling error was estimated from the computer-aided design software. Finally, the end-use implant was used to evaluate the additive manufacturing error. The results were verified using accurate measurement instruments and techniques. A worst-case cumulative error of 1.7 mm (3.0%) was estimated for one boundary condition and 2.3 mm (4.1%) for two boundary conditions considering the maximum length (56.9 mm) of the end-use implant. Uncertainty from the clinical imaging to the end-use implant was 0.8 mm (1.4%). This study helps practitioners establish and corroborate surgical practices that are within the bounds of an appropriate accuracy for clinical treatment and restoration.

Since talking to other therapists there seems to be some debate about the effectiveness and use of custom-made pressure garments in the treatment of hand injury. Those of us who make our own in a matter of minutes with the patient sat in front of us, know that they can be a fast means of reducing oedema in the digits and the hand, and in the longer term use can flatten potentially hypertrophic scars that can cause contracture. Lycra pressure garments are safer to use with unreliable patients than coban bandage, because they are made to fit the patient. For anyone in doubt I offer the following case study for you to compare with Sonia Ranelli's patient in the Spring 1998 issue of the British Journal of Hand Therapy, who was unable to wear a pressure garment when she returned to work as a veterinary nurse.

Virtual reality technologies have been demonstrated to produce encouraging results in the educational process. However, adoption of virtual reality-based instruction among educators has yet to see significant numbers. One of the reasons is the technical difficulty in authoring custom-made VR experiences for students. In this paper, we propose criteria for choosing VR authoring tools that are appropriate for usage in education and apply them to such current platforms. We also present a case study of learning collaboration project that revolved around the usage of VR authoring tools. We conclude with some recommendations regarding additional features that would enhance the exploitation of current VR authoring tools in education.
