This paper presents an ontological analysis of the EPC (Event-driven Process Chain) business process modeling notation supported in the ARIS Toolset. This ontological analysis provides an interpretation of the modeling elements in EPC diagrams in terms of the UFO foundational ontology. This enables us to define the precise real-world semantics for business(More)
In this paper, we provide a semantic foundation for role-related concepts in Enterprise Modelling. We use a conceptual modelling framework to provide a well-founded underpinning for these concepts. We review a number of Enterprise Modelling approaches in light of the concepts described (namely, ARIS, Archimate, DoDAF, RM-ODP and BPMN). This allows us to(More)
—This paper focuses on the issue of ontological interpretation for the ARIS organization modeling language with the following contributions: (i) providing real-world semantics to the primitives of the language by using the UFO foundational ontology as a semantic domain; (ii) the identification of inappropriate elements of the language, using a systematic(More)
This paper focuses on the issue of ontological analysis for organizational structure modeling in the ARIS method with the following contributions: (i) an interpretation of the language in terms of real-world entities in the UFO foundational ontology; (ii) the identification of inappropriate elements of the language, using a systematic ontology-based(More)
OBJECTIVE To investigate prevalence of invasive candidiasis in a Neonatal Intensive Care Unit and to evaluate oral diseases and Candida spp. colonization in low birth weight preterm newborns. METHODS A descriptive epidemiological study performed in two stages. First, prevalence of candidiasis was analyzed in a database of 295 preterm patients admitted to(More)
To perform a systematic review of the literature on the control of oral biofilms and the incidence of nosocomial pneumonia, in addition to assessing and classifying studies as to the grade of recommendation and level of evidence. The review was based on PubMed, LILACS, and Scopus databases, from January 1st, 2000 until December 31st, 2012. Studies(More)
UNLABELLED Liver transplantation has become a standard treatment for end-stage liver disease and the number of recipients has grown rapidly in the last few years. Dental care during pre-transplant workup is important to reduce potential sources of infection in the drug-induced immunosuppression phase of liver transplantation. OBJECTIVES The objectives of(More)
The term noma is used to describe a spreading, invasive gangrene with edema of the face which starts as an ulcer of the mucous membrane and extends from in outwardly, rapidly perforating and destroying soft tissues and bone and almost always rapidly fatal. The disease occurs mainly in children from deprived areas with low levels of hygiene. Cases of(More)
Oral verruciform xanthoma (OVX) is an uncommon lesion that appears on the oral mucosa. The aim of this paper was to discuss the probable etiopathogenesis of OVX in the hard palate, reinforcing the importance of including this lesion in the differential diagnosis of verrucous lesions. A 43-year-old male smoker presented with a painless lesion with a(More)
