A framework for working with digitized cultural heritage artefacts

In this paper, we present our work in designing, implementing, and evaluating a set of 3D interactive spatial measurement tools in the context of Cultural Heritage Toolbox (CH Toolbox), a framework for computer-aided cultural heritage research. Our application utilizes a bi-manual, spaceball and mouse driven user interface to help the user manage visualized 3D models digitized from real artifacts. We have developed a virtual radius estimator, useful for analyzing incomplete pieces of radial artifacts, and a virtual tape measure, useful in measurement of geodesic distances between two points on the surface of an artifact. We tested the tools on the special case of pottery analysis

A software system to work with 3D models in cultural heritage research

The availability of intuitive, user-friendly and specialized software to work with 3D models of cultural heritage artifacts is as important as the availability of lowcost and robust data acquisition techniques for the adoption of digitized 3D models in cultural heritage research. As recent developments in 3D scanning technologies have made the digitization of artifacts affordable; the amount of digitized models available for research increases rapidly. Consequently the need for specialized software for cultural heritage research and practice on 3D models becomes more apparent. The lack of spatial measurement tools familiar to cultural heritage experts in traditional 3D modeling packages motivated us to create a simple, freely available, and extensible measurement tools system, CH Toolbox, which was designed exclusively for cultural heritage research. The proposed system visualizes digitized models of artifacts in 3D and allows the user to analyze the pieces using a spaceball and mouse driven bi-manual interface. We describe here the component of the CH Toolbox system, specificially the virtual tape measure, caliper, rim chart and an surface area estimation tool. Additionally, we present justification for CH Toolbox’s bi-manual interaction scheme according to Guiard’s Kinematic Chain model for asymmetric human skilled bimanual actions. We also discuss the design decisions that were taken for producing an extensible and free software system based on open standards and widely available open source technologies, such as the OpenGL graphics and the OpenSceneGraph scene hierarchy libraries

Risk factors for malignancy in systemic sclerosis patients

Annual Meeting of Spondyloarthritis-Research-and-Treatment-Network (SPARTAN) -- JUL 25-26, 2015 -- Denver, COWOS: 000376281000017PubMed ID: 27118199Systemic sclerosis (SSc) is an autoimmune connective tissue disease with multisystem involvement. An increased incidence of cancer in SSc patients compared with the general population has been reported in several reports. Our aims in this study were to determine the most common malignancies and to investigate the possible risk factors for the development of malignancy in patients with SSc. Three hundred forty SSc patients from 13 centers were included to the study. Data of the patients were obtained by evaluating their medical records retrospectively. A total of 340 patients with SSc were evaluated. Twenty-five of the patients had 19 different types of malignancy. Bladder cancer was the most common type of cancer with four patients and was followed by breast cancer with three patients, and cervix cancer and ovarian cancer with two patients each. Other types of cancers such as squamous cell skin cancer, adenocancer with an unknown origin, multiple myeloma, chronic myeloid leukemia, papillary thyroid cancer, larynx cancer, non-small cell lung cancer, follicular type non-Hodgkin lymphoma (NHL), endometrium cancer, colon cancer, uterus cancer, neuroendocrine tumor, glioblastoma multiforme, and soft tissue sarcoma were diagnosed in one patient each. The only cancer type that showed an association with cyclophosphamide dose was bladder carcinoma. Other malignancies did not show a correlation with age, sex, smoking, type and duration of the disease, autoantibodies, organ involvement, and dose and duration of cyclophosphamide therapy. Cancer may develop in any organ in patients with SSc. Continuous screening of the patients during a follow-up period is necessary for the early detection of the tumor development.Spondyloarthritis Res & Treatment Networ
