Nurse Faculty Enrichment and Competency Development in Oral-Systemic Health
Nurses are positioned to play a significant role in oral health promotion and disease prevention across the life cycle. Oral health has not been a high priority in nursing practice, and educating nurses about oral health has been inadequate particularly regarding the interrelationship between oral health and overall health. The first step for developing a nursing workforce with core competencies in oral health promotion and disease prevention is to prepare nurse faculty with the requisite knowledge, skills, attitudes, and best practices in oral-systemic health. The purpose of this paper is to present Smiles for Life: A National Oral Health Curriculum as a knowledge framework that nurse faculty can use for faculty enrichment and competency development in oral health across the life cycle. A variety of teaching-learning strategies and resources are provided to assist nurse faculty with integrating oral-systemic health into existing nursing curricula
Electric power scheduling: A distributed problem-solving approach
Space Station Freedom's power system, along with the spacecraft's other subsystems, needs to carefully conserve its resources and yet strive to maximize overall Station productivity. Due to Freedom's distributed design, each subsystem must work cooperatively within the Station community. There is a need for a scheduling tool which will preserve this distributed structure, allow each subsystem the latitude to satisfy its own constraints, and preserve individual value systems while maintaining Station-wide integrity. The value-driven free-market economic model is such a tool
Oral Health Nursing Education and Practice Program
Millions of Americans have unmet oral healthcare needs and profound oral health disparities persist in vulnerable and underserved populations, especially poor children, older adults, and racial and ethnic minorities. Nurses can play a significant role in improving the quality of oral health including access to care with appropriate education and training. The purpose of this paper is to describe New York University College of Nursing's response to this challenge. The Oral Health Nursing Education and Practice (OHNEP) program is a national initiative aimed at preparing a nursing workforce with the competencies to prioritize oral disease prevention and health promotion, provide evidence-based oral healthcare in a variety of practice settings, and collaborate in interprofessional teams across the healthcare system. The overarching goal of this national initiative is to create an educational infrastructure for the nursing profession that advances nursing's contribution to reducing oral health disparities across the lifespan
The finite index basis property
We describe in this paper a connection between bifix codes, symbolic dynamical systems and free groups. This is in the spirit of the connection established previously for the symbolic systems corresponding to Sturmian words. We introduce a class of sets of factors of an infinite word with linear factor complexity containing Sturmian sets and regular interval exchange
sets, namely the class of tree sets. We prove as a main result that for a uniformly recurrent tree set S, a finite bifix code X on the alphabet A is S-maximal of S-degree d if and only if it is the basis of a subgroup of index d of the free group on
Celiac disease in pediatric patients according to HLA genetic risk classes: a retrospective observational study
Background: Celiac disease (CD) is an autoimmune enteropathy in which HLA-DQ haplotypes define susceptibility. Our aim was to evaluate if belonging to a certain HLA-DQ class risk could be associated to the clinical, serological and histological presentation of CD. Methods: We performed a retrospective observational monocentric study including all 300 patients diagnosed with CD, who underwent HLA typing. Clinical, serological and histological data was collected from clinical records and their association with HLA-DQ class risk was verified through statistical tests. Results: In our sample mean age at onset was 6.7 ± 4.2 years, with a prevalence of females (n = 183; 61%), typical symptoms (n = 242; 80.6%) and anti-tTG IgA ≥ 100 U/mL (n = 194; 64.7%). Family history was present only in 19% (n = 57) of patients, and it was not significantly associated with any of the clinical and demographical data analyzed or the belonging to a certain HLA-DQ class risk. We found in the male population more frequently a coexistence of CD and atopic syndrome (males: n = 47; 40.2%; females: n = 50; 27.3%; p = 0.020). Early age of onset, instead, was associated with typical symptoms (m = 6.4 ± 4; p = 0.045) and elevated liver enzymes (m = 5 ± 3.8; p < 0.001), while later age of onset was associated with presence of other autoimmune diseases (m = 8.2 ± 4; p = 0.01). We observed statistically significant influences of HLA class risk on antibodies and liver enzymes levels: G1, G4 and G2 classes showed more frequently anti-tTG IgA ≥ 100 U/mL (n = 44; 80%, n = 16; 69.6%, n = 48; 67.6% respectively; p-value = 0.037), and in patients from G2 class we found enhanced liver enzymes (n = 28; 39.4%; p-value = 0.005). HLA class risk was still significantly associated with anti-tTG ≥ 100 (p = 0.044) and with hypertransaminasemia (p = 0.010) after a multiple logistic regression adjusted for the effect of gender, age at onset and family history. Conclusions: We failed to prove an association between HLA-DQ genotypes and the clinical features in our CD pediatric patients. Although, our results suggest an effect of the DQB1–02 allele not only on the level of antibodies to tTG, but possibly also on liver involvement
Behavior and Strengthening of RC Beam-Column Joints: Experimental Program and First Results of the Research Activity in the Framework of DPC-ReLUIS Project (Research Line 2)
The 2005-2008 DPC-Reluis Project, funded by the Italian Department of Civil Protection (DPC), is made up of
ten Research Lines (RL). RL 2 specifically focuses on the seismic performance of existing RC buildings and is,
in turn, organised in nine different Tasks. In the paper, the design of the research activities being carried out
within the Task 7 by the four involved Research Units (RU UNIBAS, RU UNIUD, RU UNISA, and RU
UNINA) and some first results are reported. Main objective of Task 7 is to investigate on the experimental
behaviour of beam-column joints without or with strengthening, thus providing a contribution to a more reliable
evaluation of the seismic vulnerability of Reinforced Concrete existing buildings. To this purpose the main
activities carried out have been devoted to design and set up of wide experimental programs on beam-column
joints relevant to typical existing RC buildings having different Earthquake Resistant Design (ERD) level, to
make a literature review of the state of the art on the subject, to perform numerical simulations based on some
analytical models available in literature in order to fully understand the mechanical behaviour. Further, some
results of the tests already carried out are reported, analysed and compared in order to understand the failure
mechanism and evaluate the seismic performance of joints with and without ERD
