These approaches provide the key to increasing stakeholder engagement associated with Operation and Maintenance (O&M) procedures of living and working areas, buildings, and other built environment spaces. We present a generic and fast approach to process and analyze given 3D point clouds of typical indoor office spaces to create corresponding up-to-date approximations of classified segments and object-based 3D models that can be used to analyze, record and highlight changes of spatial configurations. The approach is based on machine-learning methods used to classify the scanned 3D point cloud data using 2D images. This approach can be used to primarily track changes of objects over time for comparison, allowing for routine classification, and presentation of results used for decision making. We specifically focus on classification, segmentation, and reconstruction of multiple different object types in a 3D point-cloud scene. We present our current research and describe the implementation of these technologies as a web-based application using a services-oriented methodology.

Theoretische Erwägungen und empirische Befunde legen jedoch nahe, dass es sich bei pathologischen Krankheitsängsten eigentlich um eine Angststörung handelt. Innerhalb des vorliegenden Beitrags wird dafür argumentiert, dass Defizite in der aktuellen Behandlungspraxis und in der Wahrnehmung von Patienten mit Hypochondrie als „schwierige Patienten“ teilweise auf Unklarheit in der Nosologie sowie bezüglich der entscheidenden Mechanismen der Entstehung und Aufrechterhaltung zurückzuführen sind. Ausgehend von innovativen theoretischen Ansätzen zur Erklärung pathologischer Krankheitsängste werden Vorschläge für eine verbesserte therapeutische Praxis skizziert. Der Fokus liegt hierbei auf einem verstärken Einsatz expositionsbasierter Behandlungselemente, die sich am „Inhibitory-learning“-Ansatz orientieren und sich bei anderen Angststörungen bereits bewährt haben. N2 - Up to now pathological health anxiety has been classified primarily as a somatoform disorder or a somatic symptom disorder in ICD and DSM. Theoretical and empirical evidence, however, suggest that pathological health anxiety basically represents an anxiety disorder. In this paper, it is argued that deficits in the treatment and perception of patients with pathological health anxiety as "difficult patients" are partly attributable to a lack of clarity in terms of nosology and with respect to central mechanisms of etiology and pathogenesis. Based on novel theoretical approaches for the explanation of pathological health anxiety, suggestions for an improved therapeutic practice are outlined. This approach focuses on a more intensive use of exposure-based treatment elements that are oriented to the inhibitory learning approach, which has already proven its effectiveness for other anxiety disorders.
