Using ICT to Support Individual Guidance in Health Promotion Programs for Increased Physical Activity.

Introduction: We report on experiences in implementing a system to support the individual guidance of training in health promotion programs aiming to increase participants' regular level of physical activity.

Methods: We used an iterative development approach considering data privacy and security aspects, followed by a phase of field testing and continuous further development.

Results: Our preliminary results comprise identified clinically relevant parameters, suitable data collection methods, experienced privacy and security challenges and a glance on our developed prototype system.

The influence of occlusal forces on force delivery properties of aligners during rotation of an upper central incisor.

Objective: To determine the forces and moments delivered to a maxillary central incisor during rotation with aligners when a simulated occlusal force generated during swallowing acts on the appliance.

Materials And Methods: Five identical appliances were manufactured from four different starting materials (Erkodur 0.8 mm and 1.

Initial forces and moments delivered by removable thermoplastic appliances during rotation of an upper central incisor.

Objective: To determine the forces and moments delivered to a maxillary central incisor during rotation by three different thermoplastic appliances with identical thickness.

Materials And Methods: Five identical appliances were manufactured from each of three materials (Ideal Clear 1.0 mm, Erkodur 1.

[Mandatory calibration of dosimeters used in radiotherapy].

In the Federal Republic of Germany, therapy level dosimeters have been subjected to mandatory verification since January 1st, 1983. This paper informs of the legal foundations and the numerous regulations, which must be observed in particular by the manufacturers and users of these dosimeters. Moreover, the paper reports on the actual state of the pattern approvals of therapy level dosimeters, the experiences gained and the results of the verifications until November 1st, 1985.
