Public Health Nursing In British Columbia from 1960 to 2005 : Transformations in Policy and Governance Structure--A Historical Review

A great portion of the history of public health nursing in British Columbia is intricately linked to major public policy developments and changes in governance structure through the years. This link is not often well understood in discussions about the role of Public Health Nurses and their shifting scope of work. Understanding this link will help us identify the ways in which Public Health Nurses have come to preserve health, control disease, and treat illnesses in the province. The focus of this Scholarly Practice Advancement Research project is to examine the historical development of public health nursing in British Columbia during the period from 1960 to 2005 through the lens of public policy and governance structure. Using historical research, including oral nursing history, the project examined what key policy documents, reports, and major developments have influenced nursing practice in public health from 1960 to 2005 in British Columbia, with a particular focus on the City of Vancouver as a case example. This project further complements a series of oral history interviews with Public Health Nurses recently completed within the UBC Consortium for Nursing History Inquiry and deposited into the UBC Archives collection, and it provides historical context to the stories of the nurses who have been interviewed. By capturing the history of policy development in public health nursing, this project shows how Public Health Nurses’ work has shifted in response to the sociopolitical environment and the restructuring of the health care system in British Columbia.Applied Science, Faculty ofNursing, School ofUnreviewedGraduat

Thickness optimization of Sn–Pb alloys for experimentally measuring mass attenuation coefficients

An attempt has been made to experimentally investigate the optimum thickness in order to measure mass attenuation coefficients for some Sn–Pb alloy systems at incident photon energies 122, 511 and 662keV. The Sn–Pb alloys were synthesized with different compositions and different thicknesses using melt-quench technique and cast iron mould. The physical parameters such as mass, thickness, density have been measured for all the prepared alloys. Further, the transmitted photon spectra of Cs-137, Co-57 and Na-22 radioactive isotopes were recorded using GAMMARAD5 (scintillator detector) of dimensions 76mm×76mm with and without inserting different alloy samples between the radioactive isotopes and detector. The experimental results so obtained were compared with the theoretical ones of WinXCom and optimum thickness for measuring mass attenuation coefficients for the selected alloys has been recommended

Bilateral fusion of permanent mandibular incisors with Talon's cusp: A rare case report

Whenever nature diverts from the “normal or usual” it gives rise to something called “abnormal or unusual,” which we call “a Disorder”. Fusion of two teeth is a common developmental disorder that is seen by a clinician. However, bilateral fusion along with Talon's cusp is very rarely seen and reported in literature. This article describes a rare case of the bilateral fusion of permanent mandibular central and lateral incisors, along with presence of Talon's cusp on the left fused teeth

Effects of a screen-based calming device on agitated behaviors of dementia: a pilot study in a residential care home

Mindful Garden (MG) is a digital platform resembling a flat-screen TV with touchless sensors that react to voice and motion. In this study, 13 residents of a long term care facility aged 74-100 exhibiting Behavioural and Psychological Symptoms of Dementia (BPSD) were randomly assigned to intervention (n=7) and control (n=6) groups.  On days 1-3, the intervention group received usual care plus exposure to MG during morning and evening care, events problematic for residents and staff; controls received usual care only. On day 4, both groups were exposed to MG with verbal cueing. A 26-item checklist was used to record frequency and types of disruptive BPSD exhibited; care duration was recorded in minutes. Trends in the data suggest that MG reduced BPSD and duration of care in the morning, but had minimal or a negative impact in evening care. Verbal cueing enhanced impact and may be necessary for successful implementation.   &nbsp

Experimental investigation of effective atomic numbers for some binary alloys

In the present work, the gamma ray backscattering technique was used to determine the effective atomic numbers for certain binary alloys. With the help of a muffle furnace, the binary alloys were synthesized using the melt quenching technique with different compositions of 82Pb, 50Sn, and 30Zn. The intensity distribution of backscattered photons from radioactive isotope 22Na (511 keV) was recorded with the help of GAMMARAD5 [76 mm × 76 mm NaI(Tl) scintillator detector] and analyzed as a function of both atomic number and thickness of the target material. The effective atomic numbers for the same binary alloys were also computed theoretically using the atomic to electronic cross-section method with the help of the mass attenuation coefficient database of WinXCom (2001). Good agreement was observed between theoretical and experimental results for the effective atomic numbers of all the selected alloys
