Explanatory models of co-morbid traits related to dental anxiety (DA) as described in the literature were tested and relative strengths analyzed in two groups of Danish adults, one with psychiatric diagnoses (n = 108)...Explanatory models of co-morbid traits related to dental anxiety (DA) as described in the literature were tested and relative strengths analyzed in two groups of Danish adults, one with psychiatric diagnoses (n = 108) and the other healthy incoming patients at a large dental school teaching clinic (n = 151). Dental Anxiety Scale (DAS) and self-report measures representing three co-morbidity explanatory models, 1) presence of other fears;2) anxiety sensitivity and 3) feelings of vulnerability specific to dental treatment, were collected in subscales of a 53-item questionnaire. Other items identified gender, age, education, income, avoidance behavior and dental symptoms. Frequency, chi-square, odds ratio and logistic regression analyses were performed. Results: All individuals with high DA (DAS > 13) regardless of group, demonstrated significant differences in avoidance of treatment (>2 yr.) versus lower or no anxiety. Patients with psychiatric diagnoses were three times more likely to have high DA and nearly two times more likely to have avoided dental treatment >2 yr.;25.9% reported extreme DA, compared to 9.3% of controls. Models of high general fear levels, predisposing anxiety sensitivity and vulnerability all demonstrated significant and strong association with intensity of dental anxiety in bivariate analyses. Feelings of vulnerability were the strongest predictor of DAS high anxiety, according to logistic regression analyses. Conclusion: Co-morbidity explanatory models as represented in present trait measures appear not to be competitive, but rather explain different aspects of a vulnerability model in high dental anxiety. Higher incidence of DA and treatment avoidance in psychiatric patients requires special attention.展开更多

In recent years, some methods for generating emergency alternatives have been included in practical CBR applications, but there have been no in-depth studies of these processes. In this study,we propose a new method for dynamic case retrieval with subjective preferences and objective information, which considers the personal preferences of the decision makers and changes in the attributes of the emergency as the situation develops. First,we present a formula for calculating the case similarity and changing trends in the case considered, where similar cases are obtained. Next, we describe a method for measuring the overall assessment value with respect to similar historical cases, which is obtained by aggregating the case similarity, the utility case similarity, the first response time, and the implementation effect.The subjective preferences and objective information are also integrated in the decision-making process. Finally, we present a case study based on the emergency response to a fire in a highrise building, which illustrates the applicability and feasibility of the proposed method.展开更多

Initially invented to replace the need for physical data cables, Bluetooth offers users a quick and easy way to share data files over a wireless network. Traffic engineers and transportation engineering researchers have utilized the potential opportunities that exist with Bluetooth and have implemented this technology into traffic monitoring techniques. To gain a better understanding of Bluetooth sensors and how they work, a comprehensive literature search was conducted. Twenty-five articles were studied regarding case studies of Bluetooth sensor implementation for travel time measurement. Besides reviewing the literature and previous case studies, three new case studies in the State of Delaware, USA, were also conducted and carefully analyzed. The benefits and drawbacks associated with Bluetooth technology for travel time measurements have been identified in this paper. The overall conclusion of the authors is Bluetooth alone and by itself is not a proper technology for travel time measurements. More studies need to be conducted on the accuracy and overall application, before one can confidently utilize the Bluetooth technology for travel time measurements.展开更多
