The Swedish National Audit Bureau has developed a model to present decision material in the public sector including effects on quality. In the article the model is illustrated with an example that deals with improved housing for elderly through installation of elevators in three story houses. The model consists of a social cost-benefit analysis and a financial analysis. In this case financial a...

In the metropolitan areas in Japan, in many stations, shopping areas are set up, and escalators and elevators are installed to make the stations be barrier-free. Further, many areas around the stations are being redeveloped. Railway business operators want to know how much effect these circumstances have on attractiveness of the station or number of passengers using the station. So, we performe...

Several factors can influence the ability to drive by patients with diabetes mellitus. The most important factor would be hypoglycaemia. It seems logical that hypoglycaemia unawareness would be an important risk factor for accidents. However, in everyday practice, hypoglycaemia-related accidents are rare. Moreover, it seems that only a small subset of people with diabetes is responsible for the...

Surface and underground mining, due to its technical challenges, is considered a hazardous industry. The great majority of accidents fatalities are frequently associated with ineffective or inappropriate training methods. Knowing that knowledge occupational accident causes plays significant role in safety management systems, it important systematise this kind information. primary objective syst...

The accident rate for general aviation remains high. While most general aviation accident studies have been pilot-focused, there is little research on the involvement of aircraft maintenance errors. We undertook a study to answer this question. The Microsoft Access database was queried for accidents occurring between 1989 and 2013 involving single engine piston airplanes operating under 14CFR P...

Over the course of recent decades, Brazil has become an industrialized society. From an epidemiological perspective and considering changes that have been occurring in the Brazilian population, particularly concerning demographic and epidemiological transitions, this paper discusses the need to adapt the epidemiological surveillance system in order to incorporate the surveillance of non-transmi...

BACKGROUND This study tested the effectiveness of a stair use promotion strategy in visible and hidden stairwells during intervention and post intervention follow up. METHODS A quasi-experimental study design was used with a 1 week baseline, a 3 week intervention, and post intervention at 2 and 4 weeks in 4 university buildings in San Antonio, Texas with stairwells varying in visibility. Part...

This paper presents the systems and results for the Event Detection task of the TRECVid 2008 evaluation campaign. The kind of events addressed are single-actor, without requiring detailed tracking of body parts; rather the body as a whole is considered and the interaction between people is not addressed. The events thus considered are the OpposingFlow, PersonRuns and ElevatorNoEntry. For the fi...

One of the major impediments in using computer simulation to model and optimize construction processes has been the fact that decision makers often do not have the training nor the time to check the validity of simulation models prepared by others and thus have little confidence in the results. Animation is an increasingly popular technique that can be used to verify, debug and validate simulat...
