OBJECTIVES: To demonstrate that novice dosimetry planners efficiently create clinically acceptable IMRT plans for head and neck cancer (HNC) patients using a commercially available multicriteria optimization (MCO) system. METHODS: Twenty HNC patients were enrolled in this in-silico comparative planning …

Background: Most studies on birth settings investigate the association between planned place of birth at the start of labor and birth outcomes and intervention rates. To optimize maternity care it also is important to pay attention to the entire process of pregnancy and childbirth. This study explores …

Although permeable pavements have been used all over the world in recent years to infiltrate and treat stormwater, only limited research has been undertaken to investigate and compare the long-term performance of these sustainable urban drainage system devices. This paper presents the results of an extensive …

The airline industry is one of the most affected by operational disruptions, defined as deviations from originally planned operations. Due to airlines network configuration, delays are rapidly propagated to connecting flights, substantially increasing unexpected costs for the airlines.

Background and purpose: Treatment plan verification of intensity modulated radiotherapy (IMRT) is generally performed with the gamma index (GI) evaluation method, which is difficult to extrapolate to clinical implications. Incorporating Dose Volume Histogram (DVH) information can compensate for this. …

Objective The aim of this study was to evaluate the effect of the increased cesarean rate for term breech presentation on neonatal outcome. We also investigated whether the clinical case selection for vaginal delivery applied by Dutch obstetricians led to an optimization of neonatal outcome, or whether …

THE PDCA-CYCLE MIGHT NOT BE APPLICABLE in situations where change is unplanned or emergent. In situations of planned change the Deming cycle is used worldwide and proven to be very effective. However in an emergent change process the PDCA might not be the applicable. These emergent changes increase. …

Military systems are operated in a variable way and operating conditions are generally quite demanding. At the same time, the requirements in terms of availability and reliability are high, and strict budget limitations make that the maintenance activities must be carefully planned and executed. The …

Objective: To evaluate the implementation of a multicomponent lifestyle intervention at two different worksites. Methods: Data on eight process components were collected by means of questionnaires and interviews. Data on the effectiveness were collected using questionnaires. Results: The program was …
